专利说明:

The invention relates to an unloading station and a method for unloading a conveyed goods container loaded with at least one conveyed article according to the preamble of claims 1 and 33.
DE 20 2017 106 993 U1 discloses a Fördergutbehälter with a bag body having a front wall and a rear wall, limited by the front wall and rear wall storage space and a laterally on the bag body at least partially formed between the front and rear end discharge opening. The bag body is between a closed position in which the storage space volume minimized and the conveyed material is transported with the Fördergutbehälter, and an open position in which the storage space volume maximized and the conveyed material is manually removed through the discharge opening from the Fördergutbehälter, umstellbar. An automatic discharge is neither intended nor possible.
WO 2014/044601 A1 discloses an automatic unloading of a conveyed material from a conveyed goods container in which the conveyed goods container suspended by means of a suspension carrier on a transport carrier is tilted about a tilting axis running perpendicular to the suspended conveying device. The conveyed material is dropped onto a discharge conveyor. After the drop height should be as low as possible, the Fördergutbehälter be moved just above the discharge conveyor. This has the consequence that the to be unloaded Fördergutbehälter must be moved over a long transport path in the tilted unloading, whereby the bag body of the Fördergutbehälters is heavily stressed. This considerably shortens the service life of the conveyed containers. In addition, the unloading station requires a large installation space.
N2019 / 00100-AT-00/93
EP 2 686 258 B1 relates to a suspended conveyor system with a conveying container for the automatic discharge of a loaded material to be conveyed and with an unloading station. The conveyed goods container has a horizontal bottom on which the conveyed goods can be stored for transport purposes. The floor cooperates with a lifting device which is set up to lift the bottom of the conveyed goods container loaded with at least one conveyed article in a vertical direction when the conveyable goods container is in an unloading position in such a way that the at least one conveyed item is moved by means of a pushing device a front side of a main body of the conveyed container is centrally pushed out, and wherein the pushing means comprises a slide which engages through another end face of the base body in an interior of the base body, where the at least one conveyed is when the floor is raised. For unloading, therefore, the two opposite open end faces, the liftable in the vertical direction bottom and by one of the front sides sweeping slide the pusher are required.
Comparable conveyable containers and associated suspension conveyors are also known, for example, from DE 10 2004 018 569 A1, EP 2 130 968 A1 or EP 2 196 415 A. The Fördergutbehälter described there consist of flexible materials in the form of a loop in which the conveyed material is held. For loading, these transport bags are opened from above, in order to bring the conveyed material into the loop can. Discharging takes place in that the conveyed material is either taken out of the loop laterally or ejected or, for example, according to EP 2 130 968 A1, the loop is opened downwards.
An object of the invention is to provide an improved unloading station and an improved method for automatically unloading a conveyed goods container of a suspended conveyor system. In particular, the unloading process should be accelerated and the conveyed goods can be unloaded in a particularly gentle way.
N2019 / 00100-AT-00/93
The object of the invention is achieved in that the unloading device comprises an actuating device, by which the conveyable container with the bag body about a substantially parallel to the longitudinal extent of the suspension conveyor extending tilting axis between a ready position and an unloading position is tilted, wherein in the unloading the conveyed through the Discharge opening from the Fördergutbehälter can be issued.
However, the object of the invention is also achieved in that for unloading a conveyed material from a Fördergutbehälter
i) in one step by the opening and closing device of the bag body from the closed position is moved to the open position, and ii) in a step by the unloading the Fördergutbehälter with the bag body about a substantially parallel to the longitudinal extent of the suspension conveyor longitudinal axis extending from a supply position is tilted into an unloading position, whereby the conveyed material is discharged through the discharge opening from the Fördergutbehälter.
The dispensing direction of the conveyed material extends in a direction transverse to the transport direction of the conveyed goods dispensing level. The conveyed material can thus be transported over a very short delivery path, whereby the discharge time is significantly reduced compared to the unloading stations known from the prior art. Also, a takeover level, to which the conveyed material is to be delivered, be placed essentially at the level of the discharge opening, so that a particularly gentle transfer of the conveyed goods to the takeover level is possible. The transfer level is defined for example by a conveyor. The bag body can be adjusted before the tilting of the Fördergutbehälters from the ready position to the unloading position in the open position, or it is the Fördergutbehälter already adjusted during the opening process of the bag body from the ready position to the unloading in the open position.
According to one embodiment of the invention, the Fördergutbehälter may additionally include
N2019 / 00100-AT-00/93
a hanging support for hanging transport on the overhead conveyor and with a receptacle,
- A frame, via which the bag body hangs on the suspension girder and which is pivotally mounted in the receptacle on and relative to the suspension beam about a longitudinal axis of the receptacle, whereby the bag body between the closed position and the open position is umstellbar.
The frame can be pivoted about the longitudinal axis of the receptacle without much effort, whereby the opening process and the closing operation of the bag body can be carried out particularly easily.
In an advantageous embodiment of the invention, the frame has longitudinal struts and cross struts, wherein the front wall and the rear wall of the bag body are each attached to one of the transverse struts of the frame (articulated).
The frame can form a rectangular or a substantially square outer contour. Under a rectangular and substantially square outer contour is in this context not only a correct square or rectangular shape to understand, but also an outer contour with rounded corners or projections arranged on the longitudinal struts. If the transverse struts are longer than the longitudinal struts in order to allow the widest possible front wall and rear wall, relatively long conveyed goods can be transported. Long longitudinal struts lead to a greater difference in the relative horizontal and vertical positions of the front wall and rear wall when switching between the closed position and open position. This results in a maximum width of the conveyed goods, which are transported with the Fördergutbehältern.
If the transverse struts and longitudinal struts are of substantially the same length, the storage space is optimized for a wide range of conveyed goods. In particular, it is also advantageous that in the open position, the discharge opening between the front and rear walls is widely spanned, so that the discharge process can be carried out particularly reliable and easy.
N2019 / 00100-AT-00/93
Conversely, a loading process of Fördergutbehälters is particularly easy to perform. In principle, the loading can be carried out from above through the frame or through a side wall opposite the discharge opening, if this is designed to be at least partially open. In principle, the bag body can also be loaded via the discharge opening. Loading can be done automatically or manually.
It is favorable if the opening and closing device comprises an actuating device for automatic opening and closing of the bag body, by which the frame is pivotable relative to the hanging support about the longitudinal axis such that the bag body between the closed position and the open position is convertible.
The bag body can be changed by the already existing frame between the closed position and the open position. This results in a particularly simple construction of the Fördergutbehälters. Also, the opening and closing device can be constructed particularly simple.
It also proves to be particularly advantageous if the actuator has a driver mechanism with a transport direction in the conveyed container
- upstream inlet section,
- downstream outlet section, and
- Endladeabschnitt arranged between the inlet portion and outlet portion, wherein the inlet portion forms an engageable with the frame in an abutment inclined guide slot that the frame is pivoted during transport of the Fördergutbehälters in the unloading, whereby the bag body converted from the closed position to the open position becomes.
The driver mechanism requires no drive and is therefore simple. The inlet section comprises an inclined guide slot that can be brought into contact with the frame in such a way that the frame is adjusted between different tilted positions and the pocket body is changed over from the closed position to the open position. Switching between
N2019 / 00100-AT-00/93
Closed position and open position can be carried out very gently. The product container is treated gently. In addition, can be centered in the storage space by the continuous opening process of the bag body, the conveyed, which favors the delivery of the conveyed material from the Fördergutbehälter.
It is also advantageous if the end loading section forms a substantially horizontal guide slot that can be brought into contact with the frame in such a way that the frame is held in the pivoted deflection position during the unloading process, whereby the bag body also remains in the open position.
The Fördergutbehälter can be performed during its tilting movement. The guide slot runs parallel to the transport direction of the Fördergutbehälters, as well as a tilting axis.
It also proves to be advantageous if the outlet section forms an inclined guide slot which can be brought into contact with the frame in such a way that the frame is pivoted out of the unloading station during the removal of the conveyable container, whereby the bag body is switched from the open position into the closed position.
The outlet section comprises an inclined guide slot which can be brought into contact with the frame in such a way that the frame is adjusted between different tilted positions and the pocket body is changed over from the open position to the closed position. The switching between the open position and closed position can be performed very gently. The product container is treated gently.
It may also prove to be advantageous if the actuating device has at least one opening flap movable by means of a drive between a first flap position and a second flap position for adjusting the bag body between the closed position and the open position.
N2019 / 00100-AT-00/93
The opening flap preferably acts on the frame of the Fördergutbehälters, in particular on one of the longitudinal struts. If the opening flap comprises a first opening flap and a second opening flap, the opening flaps act synchronously and preferably on the frame of the conveyed goods container, in particular on both longitudinal struts. The opening flap can be pivoted at an angle and displace the frame by means of this pivoting movement, in particular pivot. In the closed position, the opening flap is swung out of a movement path of the frame. In the open position, the opening flap is preferably below the frame and brings it into a horizontal position.
In a further possible embodiment of the unloading station it is provided that the opening flap in the second flap position has a guide surface running in the transport direction of the conveyed goods container for guiding the rack when leaving the unloading station.
By the guide surface, a desired trajectory of the conveyed container can be achieved when leaving the unloading station. Optionally, any occurring during acceleration of the Fördergutbehälters vibrations and / or vibrations can be damped, so that a total quieter ride and thus a gentler transport of the conveyed within the Fördergutbehälters are possible.
It is also possible that the frame is fixed non-positively in the second flap position between the opening flap and a guide profile. The opening flap can be pressed against the frame, so that in turn it is pressed against the guide profile. As a result, the frictional connection can be effected. By fixing the frame can be locked or fixed in addition to effecting the open position and the entire Fördergutbehälter within the loading station.
It also proves to be advantageous if the overhead conveyor for transporting the Fördergutbehälters in the unloading and removal of the Fördergutbehälters from the unloading station by a drive device or by
N2019 / 00100-AT-00/93
Gravity movable transport carrier comprises, wherein the transport carrier and the hanging support are hinged together, whereby the suspension support is pivotable about a substantially parallel to the suspension conveyor axis extending relative to the transport carrier.
The transport carriers can be moved by means of a friction lock drive or a positive locking drive. Also, an embodiment is possible in which the transport carrier can be moved autonomously by a self-propelled. The transport carriers can be transported very dynamically to the unloading station and transported away from the unloading station, which favors a high discharge capacity.
Otherwise, however, the transport carriers can also be transported by gravity, provided that the profile rail on which the transport carriers are moved has a gradient. This version is ideal if the investment costs are to be kept low.
It can also be provided that the opening and closing device of the unloading station is associated with a locking device for locking the transport carrier during a discharging process of the conveyed goods container.
The transport carrier is temporarily locked for unloading the Fördergutbehälters, whereby an unwanted movement of the transport carrier and the Fördergutbehälters in the transport direction and / or is avoided transversely to the transport direction during the tilting movement of the Fördergutbehälters. The unloading process can be carried out particularly reliably even with large and / or heavy goods.
It is also possible for the opening and closing device of the unloading station to comprise a guide device for lateral guidance of the transport carrier during a transport movement of the transport carrier through the suspended conveyor device for transporting the conveyed goods container into the unloading station and removal of the conveyed goods container from the unloading station.
N2019 / 00100-AT-00/93
The transport carrier is guided laterally for unloading the Fördergutbehälters, whereby an unwanted tilting of the transport carrier is avoided by a running in the direction of transport axis during the tilting movement of the Fördergutbehälters. The unloading process can be carried out particularly reliably even with large and / or heavy goods.
An advantageous embodiment is also possible if the actuating device of the unloading device comprises a frame which can be tilted by means of a drive about an axis extending parallel to the transport direction of the conveying goods container between a starting position and an actuating position and the actuating device of the opening and closing device is mounted on the frame.
The opening and closing device is moved together with the tiltable between the starting position and the operating position frame, whereby an opening operation of the bag body and the tilting of Fördergutbehälters simultaneously and / or a closing operation of the bag body and the Rückkippvorgang the Fördergutbehälters can be performed simultaneously.
The unloading process can be additionally accelerated. In addition, the unloading process can be performed without stopping the transport movement. In principle, however, the transport speed of the transport carrier and the conveyable container can vary on the transport movement along the unloading station.
It also proves to be beneficial if the bag body further comprises a bottom, wherein the bottom
a first longitudinal edge,
a second longitudinal edge extending at a distance to the first longitudinal edge,
a first end edge extending between the first longitudinal edge and the second longitudinal edge,
- Formed between the first longitudinal edge and the second longitudinal edge extending second end edge, and
- Wherein the discharge opening in the open position of the bag body
N2019 / 00100-AT-00/93 limited by the front wall and rear wall and adjacent to the first end edge. In particular, the front wall is provided with the bottom.
It is thus provided that the discharge opening adjoins the first end edge, which does not preclude, however, that a side wall extends between the front wall and the rear wall above the discharge opening. It is merely necessary to ensure that the discharge opening is dimensioned so that the largest conveyed material can be moved through the discharge opening without colliding with the side wall. It is particularly advantageous that, for unloading the conveyed goods container, a material lying on the ground can be conveyed through the unloading opening and over the first end edge. In this case, the first end edge also act as a tilting edge, so that a reliable unloading of the conveyable container allowed. In addition, the Fördergutbehälter can be made particularly low.
It is also advantageous if the bag body has an adjacent to the second end edge sidewall stop against which the conveyed material can be applied.
The additional sidewall stop can hold the conveyed goods in the storage space during transport. Although conventional items are held in the transport position of a respective Fördergutbehälters with sufficient holding power between the front wall, rear wall and optionally the ground, however, it proves to be advantageous if conveyed goods that differ from the standard dimensions or standard shapes are additionally held by the sidewall stop. By means of the sidewall stop so accidental falling out of the conveyed material can be avoided during transport of the Fördergutbehälters. In addition, during loading the conveyed can be inserted in a simple manner in the Fördergutbehälter until it rests against the side wall stop. An accidental falling out of the conveyed material in a possible too dynamic loading process can be reliably prevented. Preferably, the floor is inclined towards the sidewall stop to achieve even greater loading safety and / or transport safety.
N2019 / 00100-AT-00/93
The Fördergutbehälter can also be formed without additional sidewall stop. It has been shown that conventional items to be conveyed in the closed position of the Fördergutbehälters with sufficient holding power between the front wall, rear wall and possibly the ground can be maintained. As a result, the production costs for the Fördergutbehälter can be reduced to a minimum, since an additional step in the production of sidewall stop can be omitted. Such a side wall stopper is mainly cut out of a separate material web and attached to the at least one material web for the front wall, rear wall and the bottom, in particular sewn on the front wall and the bottom or the rear wall and optionally the bottom. The waiver of the sidewall stop seems at first glance trivial, but brings in view of the enormous amount in a logistics facility a considerable reduction in investment costs. If the open side wall is used as loading opening, then the conveyed goods container can be unloaded unhindered on an open first side wall and loaded on an open second side wall.
It is particularly advantageous if the first longitudinal edge forms a first folding edge and the second longitudinal edge forms a second folding edge.
The folded edges act as hinges on which the floor is hinged, and allow a relative displacement between the front wall and the rear wall. Thus, the storage space or the receiving volume can be increased and decreased. The Fördergutbehälter can be used for different sized items and / or very space-saving buffered empty or transported back. It is possible that a width of the bottom between the folded edges is between 5 mm and 800 mm. The width of the bottom between the folded edges can be varied. So there are specially adapted Fördergutbehälter conceivable.
Preferably, the bottom can form a receiving surface opening into the discharge opening (if a sidewall stop is present according to a first embodiment) or into the loading opening (if, in a second embodiment, a side wall stop is omitted) on which the conveyed goods are stored
N2019 / 00100-AT-00/93 can be used when the bag body is switched to the open position. The receiving surface may also define a sliding surface. In particular, the receiving surface extends between the two longitudinal edges and the two end edges. The receiving surface directly adjoins the first end edge and the second end edge. The conveyed material can be slidably mounted on the sliding surface of the soil. As a result, loading and / or unloading of the conveyed goods container can be simplified and, in particular, the conveyed goods can be pushed into the conveyed goods container in a particularly simple manner and pulled out again.
According to a preferred embodiment, the front wall and rear wall of the bag body on a suspended on the frame pliable material.
By means of the frame and the limp material and the bottom of the storage space can be spanned. A pliable material may be understood to mean a fabric, a film, a braid, a knitted fabric, a woven fabric and / or the like. By means of the suspended limp material, a very easy and flexibly usable Fördergutbehälter can be provided.
In addition, it is possible that the Fördergutbehälter holds the conveyed in the transport position between the ground and the pliable material, in particular clamped. The pliable material is preferably cuddly and may optionally have elastic properties. As a result, the conveyed material can be surrounded at least in regions, for example at corners and edges, tightly by the limp material. As a result, a form and / or adhesion for holding the conveyed material within the Fördergutbehälters be effected. The positive and / or positive connection can be reinforced by a gravity of the conveyed, with a self-locking can occur.
The pliable material may be at least partially planked to stiffen the Fördergutbehälters. The planking can provide a more stable body N2019 / 00100-AT / 00/93. The planking can be adapted to different transport tasks and reinforce, for example, heavily loaded areas, especially the pliable material.
According to one embodiment of the invention, it is provided that the suspension conveyor device for transporting the Fördergutbehälters into the unloading and removal of the Fördergutbehälters from the unloading station comprises a guide device and movable by a drive device along the guide device transport carrier.
According to an advantageous embodiment, it is provided that the drive device comprises a feed drive in a conveyor section along the unloading station, which feed drive
- a support frame,
- A traction mechanism mounted on the support frame with a drivable by a drive motor traction means and
- Has at least one coupled to the traction means driver finger for driving movement of the Fördergutbehälters along the guide device.
It proves to be particularly advantageous if the conveyor section forms a transport path along which the Fördergutbehälter be transported, and if the at least one driver finger is movable by the traction mechanism between a retracted from the transport path starting position and a protruding into the transport path engagement position, wherein the at least a driver fingers in the engaged position with the transport carrier or Fördergutbehälter can be brought into a positive engagement and through which the Fördergutbehälter along the conveyor section is movable.
For example, the driving finger with the transport carrier, on which the conveyed container is suspended over the suspension support, or engage with the suspension carrier form-fitting manner.
N2019 / 00100-AT-00/93
According to one embodiment of the invention, it is provided that the actuating device of the unloading comprises a by means of a drive about an axis parallel to the transport direction of Fördergutbehälter axis between a starting position and an operating position tiltable frame and that both the actuating device of the opening and closing device and the feed drive are stored on the frame.
It is also advantageous if in a conveyor section along the unloading station and upstream of the opening and closing device a Fördergutbehälter-positioning device is arranged, through which the Fördergutbehälter can be positioned relative to the opening and closing device.
According to an advantageous embodiment, the conveyor section forms a transport path along which the Fördergutbehälter be transported, wherein the Fördergutbehälter-positioning device comprises on both sides of the transport path and symmetrical to a running in the direction of the transport path vertical plane stopper elements, which by at least one drive between a the transport path retracted release position and a protruding into the transport path engagement position are movable, wherein the Fördergutbehälter is positioned against the moving in the engaged position stopper elements. For example, the Fördergutbehälter can be positioned with the frame and / or the front wall against the stopper elements moved into the engaged position, so that the Fördergutbehälter is in an exact transfer position when it is positioned against the stopper elements moved into the engaged position. Thus, the Mitnehmerfinger the feed drive the Fördergutbehälter, in particular take the suspension carrier reliable. The stopper elements are formed, for example, by stopper fingers pivotable about vertical axes between the release position and the engagement position.
It has been found in practice that the Fördergutbehälter tend by dynamic transport movements more or less to pendulum movements. The reason for this is that a Fördergutbehälter is hinged on a transport carrier or hinged to a transport carrier. Before this
N2019 / 00100-AT-00/93
In the background, it is now provided that in a conveyor section along the unloading station and upstream of the opening and closing device a Fördergutbehälter-guide device is provided by which prevents the pendulum motion or an amplitude of the pendulum motion is at least minimized. Thus, even with highly dynamic transport movements of the material to be conveyed without pendulum motion (or with sufficiently minimized pendulum motion) are passed to the opening and closing device. Thus, the opening and / closing of the bag body can be performed reliably.
According to one embodiment of the invention, it is provided that the conveying section forms a transport path along which the conveyed goods containers are transported, wherein the conveyed goods container guiding device comprises guide walls arranged on both sides of the transport path and symmetrically to a vertical plane extending in the direction of the transport path. The guide walls are preferably placed stationary and the conveyable container is moved in the transport direction relative to the guide walls. The frame of the Fördergutbehälters is guided between the guide walls and limits a pendulum motion through the guide walls.
The guide walls can also form symmetrically to the running in the direction of the transport path vertical plane and inclined towards each other in the direction of the opening and closing device tapered inlet slopes. As a result, a centering of the conveyed goods container, in particular of the bag body, relative to the transport path can be achieved.
It is also advantageous if at least one of the guide walls is provided with a driver mechanism, wherein the driver mechanism forms an inclined guide slot that can be brought into contact with the frame in such a way that the frame is pivoted into the opening and closing device during the transport of the conveyable container, thereby the bag body is switched from the closed position in the direction of the open position. The bag body is already partially opened before the opening and closing device by the frame frame slides along the guide slot.
N2019 / 00100-AT-00/93
The bag body is thus not abruptly, but continuously opened with continuous transport movement. Also included in the bag body
Material to be conveyed is moved "controlled" onto the bottom of the opened bag body during the opening movement.
It may also be advantageous if the unloading station additionally comprises a filling device below the unloading position, through which the conveyed material dropped from the conveyed goods container is received in a first step i) and in a second step ii) the conveyed goods are delivered to a receiving container. In particular, the filling device comprises a shelf and a bottom opening which can be opened and closed by the shelf.
The shelf divides the height of fall between the Fördergutbehälter and receptacle in at least two (lower) height sections. As a result, an "orderly" delivery of the conveyed material from the conveyed goods container into the receiving container is made possible. Thus, by moving the bag body from the closed position (transport position) to the open position (unloading position), the conveyed material is already moved through the rear wall in the direction of the ground. By the tilting movement of the Fördergutbehälters the conveyed slides on the ground in the direction of the discharge and then falls at an angle of less than 60 °, in particular at an angle between 30 ° and 45 ° relative to a horizontal plane on a shelf bottom of the filling. The angle results from the tilt angle of the Fördergutbehälters when it is tilted into the unloading position. As a result, even slippery conveyed goods "sorted" can be transferred to the shelf. Thereafter, the bottom opening is released through the shelf and the conveyed falls substantially vertically down into the receptacle provided below the filling. Thus, an "orderly" transfer from the filling in the receptacle is possible.
It proves to be advantageous if the unloading station additionally comprises a conveying device for transporting a receiving container into a filling position and transporting a receiving container from the filling position, which is arranged below the filling device. Thus, an automatic transport of a receptacle to be replenished and automatic removal of a filled receptacle can be performed. The filling of a receptacle takes place in accordance with a picking order. The picking order can comprise one or more conveyed goods. If several items to be conveyed are required for a picking order, the items to be conveyed are unloaded successively at the unloading station and the receiving container is filled. If all conveyed goods have been loaded into the receptacle for this picking order, the receptacle can be removed.
According to the method measure, it is provided that step i) and step ii) are carried out chronologically successively by transporting the conveyed goods container through the hanging conveyor device to the unloading station and stopping at the unloading station and thereafter
- In the first step i) the bag body is adjusted by the opening and closing device from the closed position to the open position, and then
- In the second step ii) is tilted by the unloading the Fördergutbehälter with the adjusted in the open position bag body to the substantially parallel to the longitudinal extent of the suspension conveyor longitudinal axis from the stowed position to the unloading, whereby the conveyed material is discharged through the discharge opening from the Fördergutbehälter.
The bag body is adjusted before the tilting of the (stationary) Fördergutbehälters from the ready position to the unloading position in the open position. This ensures a particularly reliable unloading process.
Another advantage is the measure in which step i) and step ii) are performed overlapping in time by the Fördergutbehälter transported by the suspension conveyor to the unloading station and continuously moved at the unloading station, wherein during the continuous transport movement of Fördergutbehälters
N2019 / 00100-AT-00/93
- In step i) the bag body is adjusted by the opening and closing device from the closed position to the open position, and simultaneously
- In step ii) is tilted by the unloading the Fördergutbehälter with the bag body to the substantially parallel to the longitudinal extent of the suspension conveyor longitudinal axis from the stowed position to the unloading, whereby the conveyed material is discharged through the discharge opening from the Fördergutbehälter.
It can be carried out simultaneously opening operation of the bag body and the tilting of the Fördergutbehälters. The unloading process can be additionally accelerated. In addition, the unloading process can be performed without stopping the transport movement. In principle, however, the transport speed of the transport carrier and the conveyable container can vary on the transport movement along the unloading station. According to these measures, discharge capacity can be maximized.
It is also advantageous if, after the unloading of the conveyed goods container or the delivery of the conveyed goods from the bag body
- In a step iii) is tipped by the unloading the Fördergutbehälter with the bag body about a substantially parallel to the longitudinal extent of the suspension conveyor extending tilting axis from the unloading position into the ready position, and
- In a step iv) the bag body is adjusted by the opening and closing device from the open position to the closed position.
The step iii) and step iv) can be performed temporally successive or temporally overlapping (simultaneously).
If step iii) and step iv) are performed consecutively in time, after tilting back the conveyed container, it is moved out of the unloading station from a stationary position. The Rückkippvorgang and the closing of the bag body follow each other (sequentially).
N2019 / 00100-AT-00/93
If step iii) and step iv) are performed overlapping in time, a closing operation of the bag body and the tipping operation of the conveyed container are carried out simultaneously. The unloading process is carried out without stopping the transport movement. In principle, however, the transport speed of the transport carrier and the conveyable container can vary on the transport movement along the unloading station. According to these measures, discharge capacity can be maximized.
For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. on the

FIGS. 1 to 10 show a section of a suspended conveyor system comprising a suspension conveyor device 1 for transporting conveyed goods containers 2 in a transport direction 3 and an unloading station 4 for automatically unloading one of the conveyable containers 2 (transport bag or hanging bag).
Specifically, the suspension conveyor 1 is provided for transporting the Fördergutbehälter 2 in the unloading station 4 and removal of the Fördergutbehälter 2 from the unloading station 4. This comprises by a drive device 5 along the suspension conveyor 1 movable transport carrier. 6
In the illustrated embodiment, the transport carrier 6 by a frictional drive (drive device 5) moves. The transport carrier 6 shown comprises a hanger 7, a rotatably mounted on an axis (first) roller 8 and a friction surface 9, the latter can be brought into frictional engagement with an endlessly circulating friction belt 10 of the overhead conveyor 1. The (second) roller 8 shown in the figures is optional and serves to guide the transport carrier 6 on a switch point. The transport carrier 6 is guided over the (first) roller 8 on a rail 11 of the overhead conveyor device 1 and can be moved by the frictional drive in the transport direction 3. The profiled rail 11 accordingly forms a guide device for the (driven or non-driven) transport carrier 6. Such a transport carrier 6 is described for example in DE 10 2011 080 280 A1, wherein the embodiment shown by the transport carrier in DE 10 2011 080 280 A1 characterized in that the hanging body 7 comprises a pivot receiver.
According to an embodiment, not shown, the transport carrier 6 can be moved by a form-locking drive (drive device 5). For this purpose, an endlessly circulating drive belt of the suspension conveyor device 1 can be provided with driver elements protruding thereon, which engage with the transport carriers 6 or the suspension carriers 13 in a form-fitting manner.
N2019 / 00100-AT-00/93
A combination of a frictionally engaged drive and positive locking drive is also possible.
The described drive devices 5 are by no means to be understood as limiting, but merely show different possibilities as to how a drive force is transmitted to the transport carriers 6 in order to move them on the suspended conveyor device 1 in the transport direction 3 (driven).
An embodiment is also conceivable in which the transport carriers 6 have a drive device and are moved on the suspension conveyor device 1 in the transport direction 3 (driven).
Regardless, a transport movement of the transport carrier 6 without a drive device would be possible by the transport carrier 6 are moved by gravity on the overhead conveyor 1 in the transport direction 3 (not driven).
As can be seen in FIGS. 1, 2 a, 2 b, 3 a, 3 b, the conveyable container 2 in a preferred embodiment comprises a suspended support 13, wherein the suspended support 13 and the transporting carrier 6 are articulated to one another via an articulated connection in such a manner that the suspended support 13 moves around a substantially parallel to the suspension conveyor 1 (or substantially parallel to the transport direction 3) extending axis 14 relative to the transport carrier 6 is pivotable.
The transport carrier 6 can be provided with a first coupling element 15 and the suspension carrier 13 with a second coupling element 16, wherein the first coupling element 15 and second coupling element 16 are coupled and form the hinge connection. The first coupling element 15 comprises a pivot receptacle 17 and the second coupling element 16 comprises a pivot bearing axis 18. The pivot bearing axis 18 is formed on a hook.
According to another embodiment, not shown, the articulated connection between the suspension beam 13 and transport carrier 6 comprises an elastic body, in particular of elastomeric material, which on the one hand with the suspension beam 13th
N2019 / 00100-AT-00/93 and on the other hand connected to the transport carrier 6. The suspension carrier 13 and transport carrier 6 are connected via the elastic body (the elastic joint connection) preferably permanently or inseparably connected to each other.
2a, 2b, a first embodiment of a conveyable container 2 for transporting a conveyed material 28 (FIG. 1) is shown, which comprises a frame and a bag body attached to the frame 20. The frame 20 forms at a mutual distance parallel transverse struts and between the transverse struts 21 at a mutual distance parallel longitudinal struts 22. The frame 20 forms a substantially rectangular or a substantially square outer contour. Preferably, a circulating wire frame is used as the frame 20.
The conveyable container 2 may also include the hanging support 13 for hanging transport on the overhead conveyor 1, which is equipped with a receptacle 23 for supporting the rack 20. The frame 20 is pivotally mounted with one of the transverse struts 21 in the receptacle 23 on and relative to the hanger support 13 about a longitudinal axis 24 of the receptacle 23. The hanging support 13 is equipped according to the embodiment shown with the second coupling element 16, for example, a suspension (hook). The conveyable container 2 can be hung on the suspension support 13 either on the transport carrier 6 or according to an embodiment not shown on the overhead conveyor 1.
The bag body forms a front wall 25 and a rear wall 26. A storage space 27 is bounded by the front wall 25 and rear wall 26. The front wall 25 is hinged at its end to the first cross member 21 and the rear wall 26 is pivotally attached at its end to the second cross member 21. Each of the frame 20 downwardly depending ends of the front wall 25 and rear wall 26 are preferably integrally connected or integrally formed with each other, so that the front wall 25 and the rear wall 26 merge directly into each other.
N2019 / 00100-AT-00/93
The bag body has on one of the side walls an at least partially between the front and rear walls 25, 26 formed Endladeöffnung 29, through which a conveyed material 28 from the Fördergutbehälter 2 can be delivered (Fig. 6).
The bag body may have on one of the side walls, which is opposite to the end loading opening 29, at least partially between the front and rear walls 25, 26 arranged side wall stop 30 against which the conveyed material 28 can be applied and a lateral falling out of the conveyed material 28 from the Fördergutbehälter second to avoid.
As can be seen in FIGS. 1, 2 a, 2 b, 3 a, 3 b, 5, the pocket body can be switched by pivoting the frame 20 between a closed position (transport position) and an open position. In the closed position of the storage space 27 is minimized volume (for example, Fig. 1 - right Fördergutbehälter 2 before unloading) and it is conveyed 28 transported with the Fördergutbehälter 2. In the open position, the storage space 27 is maximized in volume (FIGS. 5, 6 - product container 2 during discharge) and the product to be conveyed 28 is discharged through the discharge opening 29 out of the product container 2.
After the front and rear walls 25, 26 are hinged to the frame 20, a horizontal distance is at least between the upper ends of the front and rear walls 25, 26 changed by different inclinations of the frame 20.
In the closed position, the horizontal distance is less than the corresponding horizontal distance in the open position. The horizontal distance is reduced to a minimum and results from the geometry / dimension of the conveyed material 28, which is taken up (stored) for transport in the storage space 27. The storage space 27 (transport space) between the front and rear walls 25, 26 is thereby smaller, so that the conveyed 28 is reliably held by the front and rear walls 25, 26 in the storage space 27. In addition, a comparatively space-saving transport on the suspension conveyor 1 is made possible.
N2019 / 00100-AT-00/93
In the open position, the horizontal distance is greater than the corresponding horizontal distance in the closed position. The horizontal distance is preferably increased to a maximum in order to reliably discharge the conveyed material 28 from the storage space 27.
Preferably, regardless of the geometry / dimension of the conveyed material 28, the pocket body is always changed over to the same open position, which allows a particularly simple construction of the unloading station 4.
It should be noted at this point that with the Fördergutbehälter 2 different conveyed 28 can be transported, which vary in geometry / dimension. The conveyed goods 28 are, for example, cartons, film bags (so-called "polybags" made of polyethylene or polypropylene) and the like. Such film bags are mainly used in the textile industry and used for example for the packaging of T-shirts, shirts and the like.
The front wall 25 and rear wall 26 of the bag body are preferably made of a pliable material. A limp material may be understood to mean a fabric, a film, a braid, a knitted fabric, a woven fabric and / or the like. By means of the suspended limp material, a very easy and flexibly usable Fördergutbehälter 2 can be provided.
The conveyed 28 can be held, in particular in the closed position between the front and rear walls 25, 26 by the pliable material, in particular clamped.
The pliable material is preferably cuddly and may optionally have elastic properties. As a result, the conveyed material can be surrounded at least in regions, for example at corners and edges, tightly by the limp material. As a result, a positive and / or positive connection for holding the conveyed material 28 within the pocket body can be effected. The positive and / or positive connection can be reinforced by a gravity of the conveyed material 28, wherein a self-locking can occur.
N2019 / 00100-AT-00/93
In Fig. 3a, 3b, a second embodiment of a Fördergutbehälters 2 for transporting a conveyed 28 is shown, which differs from the first embodiment by the bag body. This comprises a frame 20 and a frame body 20 attached to the bag body. The frame again forms with parallel spacing parallel transverse struts and between the transverse struts 21 at a mutual distance parallel longitudinal struts 22. The frame 20 forms a substantially rectangular or a substantially square outer contour. Preferably, a circulating wire frame is used as the frame 20.
The bag body comprises the front wall 25, the rear wall 26 and a bottom 35. The front wall 25 and rear wall 26 of the bag body have a pliable material, wherein the pliable material inside or outside in the region of the front wall 25 and / or in the region of the rear wall 26 at least partially stiffened trained, in particular planked. Thereby, the front wall 25 is divided into a first front wall section (which is farther from the first transverse strut 21 than the second front wall section) and a second front wall section (which is closer to the first transverse strut 21 than the first front wall section), the front wall 25 being stiffer in the first front wall section is as in the second front wall section. The rear wall 26 is divided into a first rear wall section (which is farther from the second transverse strut 21 than the second rear wall section) and a second rear wall section (which is closer to the second transverse strut 21 than the first rear wall section), the rear wall 26 being stiffer in the second rear wall section as in the first back wall section. The first rear wall section and the first front wall section are arranged adjacent to one another.
Specifically, the front wall 25 on a planking, which forms the bottom 35 when the bag body is switched to the open position. The first front wall portion defines the bottom 35. The planking is attached to the front wall 25, for example, sewn or glued. The planking therefore serves as a stiffening of the pliable material when the bag body in the
N2019 / 00100-AT-00/93
Closed position is changed, and as a "slide" when the bag body is switched to the open position.
Instead of a planking, the front wall 25 may also form a reinforcing area in which the front wall 25 has a greater material thickness and / or a higher density. This reinforcing area forms the bottom 35 when the bag body is switched to the open position. According to this embodiment, the front wall 25 forms the bottom 35.
In other words, according to both embodiments (first embodiment - bottom is formed by a planking and second embodiment - bottom is formed by the front wall), the front wall 25 is provided with the bottom 35.
The detailed design of an exemplary Fördergutbehälters 2 is described in the Austrian patent application AT 50059/2019 and is the subject of this disclosure.
In addition, a planking 34 can be seen in the second rear wall section, which can optionally be provided, and serves in this embodiment for stiffening the rear wall 26. The planking is attached to the rear wall 26, for example, sewn or glued. The planking therefore serves as a stiffening of the pliable material when the bag body is switched to the closed position.
Instead of a planking, the rear wall 26 may also form a reinforcing region in which the rear wall 26 has a greater material thickness and / or a higher density.
Furthermore, it is conceivable that the bottom 35 has an opening into the discharge opening 29 receiving surface 36 which favors the discharge of the conveyed material 28. The receiving surface 36 may optionally define a sliding surface. The conveyed 28 can store on the receiving surface 36.
The bottom 35 forms a first longitudinal edge 37a, a second longitudinal edge 37b spaced apart from the first longitudinal edge 37a, one between the first
N2019 / 00100-AT-00/93
Longitudinal edge 37a and the second longitudinal edge 37b extending first end edge 38a, extending between the first longitudinal edge 37a and the second longitudinal edge 37b second end edge 38b. The discharge opening 29 is limited in the open position of the bag body by the front wall 25 and rear wall 26 and adjacent to the first end edge 38 a.
The first longitudinal edge 37a forms a first fold edge and the second longitudinal edge 37b forms a second fold edge. When the bag body is switched to the open position, the front wall 25 connects with the second front wall portion to the first longitudinal edge 37a and connects the rear wall 26 with the first rear wall portion to the second longitudinal edge 37a.
As can be seen in FIGS. 3 b, the bag body can have a side wall stop 30 adjoining the second end edge 38 b, against which the conveyed material 28 can be applied.
The storage space 27 of the bag body is bounded by the front wall 25 and rear wall 26. Likewise, the front wall 25 is hinged at its end (first pivot bearing) on the first longitudinal side 22 and the rear wall 26 is pivotally mounted with its end (second pivot bearing) on the second longitudinal side 22. It can be seen that by means of the first pivot bearing, the second pivot bearing, the first folding edge and the second folding edge, a four-bar linkage is formed, whereby the bag body can be easily switched between the closed position and open position.
Each of the frame 20 downwardly depending ends of the front wall 25 and rear wall 26 are preferably integrally connected or integrally formed with each other, so that the front wall 25 and the rear wall 26 merge directly into each other.
The bag body has on one of the side walls at least partially between the front and rear walls 25, 26 formed end loading opening 29, through which a conveyed 28 from the Fördergutbehälter 2 can be issued.
N2019 / 00100-AT-00/93
The conveyable container 2 may also comprise the hanging support 13 for hanging transport on the overhead conveyor 1, which is equipped with a receptacle 23 for supporting the rack 20, as described above.
As can be seen in FIGS. 3a, 3b, the pocket body can be moved between the closed position and the open position by pivoting the frame 20. In the closed position of the storage space 27 is volume minimized and it is conveyed 28 transported with the Fördergutbehälter 2. In the open position of the storage space 27 is maximized volume and it is the conveyed material 28 discharged through the discharge opening 29 from the Fördergutbehälter 2.
After the front and rear walls 25, 26 are pivotally mounted on the frame 20, a horizontal distance is changed by different inclinations of the frame 20 at least between the upper ends of the front and rear walls 25, 26, as described above.
In FIGS. 1, 12a and 12b, the unloading station 4 is shown in different views. This comprises the suspension conveyor 1 for transporting the Fördergutbehälters 2 in the unloading station 4 and removal of the Fördergutbehälters 2 from the unloading station 4, a (first embodiment of) opening and closing device 40 for adjusting the bag body between the closed position and the open position and a discharge device 39 for Discharging the adjusted in the open position bag body.
The opening and closing device 40 comprises an actuating device for automatic opening and closing of the bag body, by means of which the frame 20 is pivotable about the longitudinal support 24 relative to the hanging support 13 so that the bag body can be moved between the closed position and the open position.
According to a first embodiment, the actuating device for automatic opening and closing of the bag body comprises a driving mechanism. The driver mechanism preferably comprises a first driver mechanism 41 and
N2019 / 00100-AT-00/93 a second driving mechanism 42, which are arranged on both sides and below the suspension conveyor 1 for transporting the Fördergutbehälters 2 in the unloading station 4 and removal of the Fördergutbehälters 2 from the unloading station 4. In particular, the first driver mechanism 41 and second driver mechanism 42 with respect to the Fördergutbehälters 2, in particular of the frame 20, arranged symmetrically to each other. In principle, however, only one of the driving mechanisms 41 can be provided.
The first driver mechanism 41 is attached to a first support frame 43 and the second driver mechanism 42 is attached to a second support frame 44. The first support frame 43 and second support frame 44 are part of the actuator.
In the illustrated embodiment, the first cam mechanism 41 includes a lower guide assembly and an upper guide assembly, and the second cam mechanism 42 includes a lower guide assembly and an upper guide assembly. The lower guide assembly and upper guide assembly are spaced above each other, so that between the lower guide assembly and upper guide assembly of the first cam mechanism 41 and between the lower guide assembly and upper guide assembly of the second cam mechanism 42 each one of the longitudinal struts 22 can be added. The distance corresponds essentially to the diameter of the longitudinal brace 22. The first driver mechanism 41 and / or second driver mechanism 42 may also include only the lower guide slot.
The lower guide assembly and, if provided, the upper guide assembly, the first cam mechanism 41 and, if provided, the second cam mechanism 42 include in the transport direction 3 of the Fördergutbehälters 2 an upstream inlet portion 45, a downstream outlet portion 46 and between the inlet portion 45 and outlet portion 46 arranged Endladeabschnitt 47. The lower guide assembly
N2019 / 00100-AT-00/93 and, if provided, the upper guide arrangement, the first driving mechanism 41 and / or second driving mechanism 42 are parallel to the transport direction 3 of the Fördergutbehälters second
The inlet section 45 forms an inclined guide slot 48 which can be brought into abutting contact with the frame 20, in particular the longitudinal struts 22, so that the frame 20 is pivoted into the unloading station 4 during transport of the transported goods container 2, whereby the bag body moves out of the closed position in the direction the open position is changed (Fig. 4).
The Endladeabschnitt 47 forms a with the frame 20, in particular the longitudinal struts 22, so brought into abutting contact and substantially horizontal guide slot 49 that the frame 20 is held during the discharge in the pivoted deflection position, whereby the bag body remains in the open position (Figure 5).
The outlet section 46 forms a tilted guide slot 50, which can be brought into abutting contact with the frame 20, in particular the longitudinal struts 22, so that the frame 20 is pivoted out of the unloading station 4 during removal of the conveyable container 2, whereby the bag body moves out of the open position in the direction the closed position is changed (Fig. 8).
In principle, the outlet section 46 could form, according to another embodiment (not shown), a guide slot 49 which can be brought into abutting contact with the frame 20, in particular the longitudinal struts 22, such that the frame 20 moves out of the unloading station during the removal of the conveyable container 2 4 and after leaving the outlet section 46 is "abruptly" pivoted. As a result, the bag body can be switched very quickly from the open position in the direction of the closed position and the discharge cycle can be accelerated.
N2019 / 00100-AT-00/93
10, 11a and 11b, the unloading station 4 with the suspension conveyor 1 for transporting the Fördergutbehälters 2 in the unloading station 4 and removal of the Fördergutbehälters 2 from the unloading station 4, the unloading device 39 for unloading the adjusted in the open position bag body and a ( second embodiment of a) opening and closing device 53 for adjusting the bag body between the closed position and the open position shown.
The opening and closing device 53 according to a second embodiment of the actuating device for automatically opening and closing the bag body, at least one by means of a drive 51 (see Fig. 11a, 11b) between a first flap position (Fig. 11a) and a second flap position (Fig 11b) movable opening flap 52 for adjusting the bag body between the closed position and the open position.
As can be seen in Fig. 11b, the Fördergutbehälter 2 is already pivoted in its open position. For this purpose, starting from a position shown in FIG. 11a, the opening flap 52 is pivoted by an angle into a further position shown in FIG. 11b.
Actuation or pivoting of the opening flap 52 between a first flap position and a second flap position is effected by means of the drive 51. In the first flap position (FIG. 11a), the bag body is in the closed position. In the second flap position (FIG. 11b), the bag body is in the open position. The drive 51 may be a stepper motor and / or any other drive. The drive 51 and the opening flap 52 are part of an opening and closing device 53 for adjusting the bag body between a closed position (FIG. 11a) and an open position (FIG. 11b).
The actuating device or opening flap 52 for opening the Fördergutbehälters 2 moves the frame 20 between a starting position and a deflection position. In the starting position, the frame 20 is depending on
N2019 / 00100-AT-00/93
Loading approximately vertical to oblique and arranged approximately horizontally in the deflection position.
The opening flap 52 has a guide web or guide surface 54. This is located in the illustration of FIG. 11a, ie in the closed position of the bag body, in front of the folded-down frame 20. In the illustration of FIG. 11b, ie in the open position of the bag body, the frame 20 is located between the guide web 54 and a guide profile 55. Depending on the drive torque of the drive 51, it is possible that thereby the frame 20 is fixed to the longitudinal struts 21 frictionally between the guide web 54 of the opening flap 52 and the guide profile 55. Thus, as shown in FIGS. 11b, in the open position of the pocket body, the guide web 54 bears against the frame 20 and holds it in a substantially horizontal position.
As can be seen in FIG. 10, the opening flap comprises a first opening flap 52 and a second opening flap 52 which are actuated synchronously and which are transported on both sides and below the suspension conveyor device 1 for transporting the conveyable goods container 2 into the unloading station 4 and removing the conveyed goods container 2 from the delivery container 2 Unloading station 4 are arranged. In particular, the first opening flap 52 and second opening flap 52 are arranged symmetrically relative to one another with respect to the conveyed goods container 2, in particular of the rack 20. As a result, a torsion-free displacement of the frame 20 can be achieved when opening the bag body 2. Heavier conveyed goods 28 can be loaded into the conveyable container 2. In principle, however, only one of the opening flap 52 can be provided.
The first opening flap 52 is attached to a first support frame 43 and the second opening flap 52 is attached to a second support frame 44. Each opening flap 52 is associated with a guide profile 55.
/ 93
N2019 / 00100 AT-00
As shown, the guide profiles 55 are arranged on both sides and below the suspension conveyor device 1 for transporting the Fördergutbehälters 2 in the unloading station 4 and removal of the Fördergutbehälters 2 from the unloading station 4.
It is also advantageous that, in the second flap position of the opening flap 52, the guide surface 54 extending in the transport direction 3 of the conveyed goods container 2 serves to guide the rack 20 when it leaves the unloading station 4. By the guide surface 54, a desired trajectory of the bag body when leaving the unloading station 4 can be achieved. Optionally, any occurring during acceleration of the Fördergutbehälters 2 vibrations and / or vibrations can be damped, so that a total quieter ride and thus a gentler transport of the conveyed material 28 within the Fördergutbehälters 2 are possible.
As can be seen in FIGS. 1 to 9, the unloading device 39 comprises an actuating device 56, through which the conveyable container 2 with the bag body about a substantially parallel to the longitudinal extent of the suspension conveyor 1 tilting axis 57 between a staging position 58 (Fig. 5, 12a) and an unloading position 59 (Fig. 6, 12b) is tiltable, wherein in the unloading position 59, the conveyed 28 can be discharged through the discharge opening 29 from the Fördergutbehälter 2. The conveyed material 28 is preferably loaded into a non-illustrated container or on a conveying device, not shown, for example, a belt conveyor. This container can also represent the shipping carton.
In a preferred first embodiment, the conveyable container 2 is tilted with the pocket body displaced into the open position about the tilting axis 57 between a ready position 58 (FIGS. 5, 12a) and an unloading position 59 (FIGS. 6, 12b). In other words, prior to unloading in a preceding first step i), the bag body is switched to the open position - the product container 2 is now in the ready position 58, and in a subsequent second step ii) the product container 2 with the bag body adjusted into the open position pivoted about the tilting axis 57 - the Fördergutbehälter 2 is now in the unloading position 59th
N2019 / 00100-AT-00/93
After unloading the Fördergutbehälter 2 with the adjusted in the open position pocket body about the tilting axis 57 of the unloading position 59 (Fig.
6, 12a) is tilted back into the ready position 58 (FIG. 7). Thereafter, the Fördergutbehälter 2 is transported by the suspension conveyor 1.
As will be described below with reference to FIGS. 12 a, 12 b, the unloading station 4 can be provided with a locking device 70 for locking the transport carrier 6 during a discharging process of the conveyed goods container 2. The locking of the transport carrier 6 takes place after the conveyable container 2 has reached the ready position 58.
According to a second embodiment of the conveyable container 2 is tilted during the Umstellbewegung the bag body between the closed position and the open position about the tilting axis 57 between the ready position 58 and the unloading position 59. In other words, for unloading is still tilted during the opening process of the bag body from the closed position in the direction of the open position of the Fördergutbehälter 2 about the tilting axis 57 of the supply position 58 in the unloading position 59. Similarly, after unloading during the closing operation of the bag body from the open position in the direction of the closed position of the Fördergutbehälter 2 can be tilted about the tilting axis 57 of the unloading position 59 in the ready position 58.
The actuating device 56 of the unloading device 39 comprises a frame 61 which can be tilted by means of a drive 60 about an axis running parallel to the transport direction 3 of the conveyable material container 2 between an initial position and an actuating position. The drive 60 is, for example, a fluid cylinder.
In the illustrated embodiment, the frame 61 is supported by guide assemblies 62 on a stationary upright support structure 63. The guide assemblies 62 each comprise guide slots 64 and rollably supported guide rollers 65, 66 (FIGS. 1, 12a). The guide slots include the (left) first guide slot 64 and the (right) second guide slot 64. The first guide slot 64 is attached to a first support frame 67 and the second guide track 64 is secured to a second support frame 68 , The frame 61 has mutually opposite frame sides, wherein the guide rollers 65, 66 are arranged on the first frame side and the guide rollers 65, 66 on the second frame side.
As shown in dashed lines only in Fig. 12b for the sake of clarity, the operating device of the opening and closing device 40; 53 mounted on the tiltable frame 61.
Concretely, the first driving mechanism 41 having the first supporting frame 43 and the second driving mechanism 42 is the second supporting frame 44 according to the first embodiment or the first opening flap 52 having the first supporting frame 43 and the second opening flap 52 having the second supporting frame 44 according to the second embodiment attached to the frame 61 via frame connections 69.
Thus, the opening and closing device 40; 53 tilted together with the frame 61 and it is the Fördergutbehälter 2 also in the unloading position 59 (between the lower guide assembly and upper guide assembly of the first cam mechanism 41 and, if present, between the lower guide assembly and upper guide assembly of the second cam mechanism 42 each one of the longitudinal struts 22 according to the first embodiment or between the first opening flap 52 and the first guide profile 55 and, if present, between the second opening flap 52 and the second guide profile 55) held substantially fixed.
In Figs. 12a, 12b, the unloading station 4 with the first embodiment of the opening and closing device 40 is shown. In Fig. 12a is the Fördergutbehälter 2 in the ready position 58 and the bag body in its open position (see also Fig. 5). In Fig. 12b is the Fördergutbehälter 2 in the unloading position 59 and the bag body in its open position (see also Fig. 6).
N2019 / 00100-AT-00/93
The unloading station 4 according to this embodiment additionally comprises a locking device 70 for locking the transport carrier 6 during a discharging process of the conveyed goods container 2.
The locking device 70 comprises for locking the transport carrier 6 by means of a drive 71 between an inoperative starting position (Fig. 12a) and an operative operating position (Fig. 12b) movable locking member 72. The locking member 72 includes, for example, a stop against which a profile web 73 of the Transport carrier 6 runs up and positioned the transport carrier 6 in the transport direction 3. The locking of the transport carrier 6 takes place when the conveyable container 2 has been stopped and has reached the ready position 58. The ready position 58 is monitored by a sensor 74, for example a proximity sensor.
The unloading station 4 may further include a parallel to the transport direction 3 extending guide device 75 for lateral guidance of the transport carrier 6 during a transport movement of the transport carrier 6 by the overhead conveyor 1 for transporting the Fördergutbehälters 2 in the unloading station 4 and removal of the Fördergutbehälters 2 from the unloading 4. In addition, the guide device 75 during the unloading process and when the Fördergutbehälter 2 between the stowage position 58 and unloading position 59 is tilted about the tilting axis 57 is effective by the transport carrier 6 against a sideways movement (transverse to the transport direction 3) fixed or a sideways movement (transverse to the transport direction 3) is limited.
As shown exclusively in FIGS. 12a, 12b, a receiving profile 76 extending parallel to the transport direction 3 is provided in the unloading station 4, on which the guide device 75 and / or the sensor system 74 and / or a pressure unit 77 are mounted. As described above, a friction lock drive (drive device 5) can be used to drive the transport carriers 6. In this case, it may prove advantageous if the pressing unit 77 presses the transport carrier 6 against the friction belt 10 with a pressing means acted upon by a spring force. In this case, the locking member 72 in the
N2019 / 00100-AT-00/93
Actuating position with an unlocking force effective against the spring force lift the transport carrier 6 from the friction belt 10, so that the Fördergutbehälter 2 remains in the ready position 58 and is not acted upon by a driving force. It should be expressly understood that such a pressing unit 77 can also be omitted.
The method for unloading a conveyed material 28 from a conveyed goods container 2 will be described with reference to FIGS. The conveyable containers 2 can be dammed up one behind the other in front of the unloading station 4 in the transport direction 3 (FIG. 1) and then separated via a separating device, not shown, before one of the conveyable containers 2 is transported to the unloading station 4.
In the unloading station 4, the bag body is moved from the closed position into the open position in a step i) by the opening and closing device 40.
The Fördergutbehälter 2 is moved by the overhead conveyor 1 in the transport direction 3 and at the unloading station 4, the frame 20 contacts the inlet section 45 so that the frame 20 is pivoted by the transport movement, that the bag body from the closed position in the direction of the open position is switched (Fig. 4).
As a result of the continuous transport movement of the conveyed goods container 2, the frame 20 reaches the end-loading section 47 and is pivoted in such a way that the bag body is completely converted into the open position and held in the open position (FIG. 5).
The Fördergutbehälter 2 is then stopped for a short time. In the stopped position, the conveyed material container 2, which has been converted into the open position, is in the ready position 58 (FIGS. 5, 12a).
In a step ii) by the unloading device 39 of the conveyed container 2 with the (according to this embodiment) in the open position adjusted pocket body to the substantially parallel to the longitudinal extent of the overhead conveyor extending longitudinal axis 57 from the ready position 58 tilted into the unloading position 59, whereby the conveyed 28 discharged through the discharge opening 29 from the Fördergutbehälter 2, in particular ejected (Fig. 6, 12 b). If the locking device 70 is provided, the transport carrier 6 can be locked during the unloading process of the conveyed goods container 2.
After the unloading process (dispensing operation), the material to be conveyed container 2 is tilted back by the unloading device 39 with the bag body adjusted into the open position about the longitudinal axis 57 from the unloading position 59 into the ready position 58 (FIGS. 7, 12a). If the locking device 70 is provided, the transport carrier 6 can also be locked during the tilting back (as a step of the unloading process) of the conveyed goods container 2.
Subsequently, the conveyable container 2 is moved by the hanging conveyor device 1 in the transport direction 3 and contacted the frame 20, the outlet portion 46 so that the frame 20 is pivoted by the transport movement, that the bag body from the open position in the direction of the closed position is switched (Fig. 8). If the locking device 70 is provided, the transport carrier 6 is released for the time being in order to allow a transport movement in the transport direction 3 again.
Due to the continued transport movement of the conveyed goods container 2, this emptied or partially emptied leaves the unloading station 4 (FIG. 9).
According to another embodiment, the step i) and step ii) are performed overlapping in time by the Fördergutbehälter 2 transported by the hanging conveyor 1 to the unloading station 4 and continuously moved along the unloading station 4, wherein during the continuous transport movement of the Fördergutbehälters 2 in step i) the bag body 2 is adjusted by the opening and closing device 40 from the closed position to the open position, and simultaneously in step ii) by the unloading device 39 of the conveying container 2 with the bag body about the longitudinal axis 57 extending substantially parallel to the longitudinal extent of the hanging conveyor device 1 from the ready position 58 is tilted into the unloading position 59, whereby the conveyed 28th
N2019 / 00100-AT-00/93 is discharged through the discharge opening 29 from the Fördergutbehälter 2. It is possible that the transport speed varies during the transport movement along the unloading station 4, but always greater than zero.
In other words, the Fördergutbehälter 2 is tilted during the Umstellbewegung the bag body between the closed position and the open position about the tilting axis 57 between the ready position 58 and the unloading position 59. In this case, for unloading is still tilted during the opening process of the bag body from the closed position in the direction of the open position of the Fördergutbehälter 2 about the tilting axis 57 of the supply position 58 in the unloading position 59. Similarly, after unloading during the closing operation of the bag body from the open position in the direction of the closed position of the Fördergutbehälter 2 can be tilted about the tilting axis 57 of the unloading position 59 in the ready position 58. According to this embodiment, the locking device 70 described above for locking the transport carrier 6 can be omitted.
FIGS. 13 to 20, 21 a, 21 b and 21 c show a section of a suspended conveyor system comprising the suspended conveyor device 1 for transporting conveyed goods containers 2 in the transport direction 3 and a modified embodiment of an unloading station 4 for automatically unloading the conveyable containers 2 (transport bag or hanging bag). shown.
The suspended conveyor device 1 shown for transporting the conveyable containers 2 into the unloading station 4 'and removing the conveyed containers 2 from the unloading station 4' comprises in different conveyor sections 80a, 80b, 80c a guide device 81 and by one of the above-described drive devices 5 or a combination of those described above Drive devices 5 along the guide device 81 (driven) movable transport carrier. 6
N2019 / 00100-AT-00/93
The overhead conveyor system may also include a suspended conveyor (not shown) for transporting conveyable containers 2 having a guide device 81 and transport carriers 6 movable along the guide device 81 (not driven).
The overhead conveyor system may also include only the guide device 81 and the transport device 6 (driven) movable along the guide device 81 by the drive device (s) 5 described above.
Such a transport carrier 6 is described for example in the Austrian patent application AT 50092/2019.
The guide device 81 is formed on the rail 11.
In the embodiment shown, the transport carrier 6 described above
- In a along the unloading station 4 'arranged conveying section 80c by a form-locking drive (drive device) and
- Moved in a conveyor section 80c upstream conveying section 80a (for transporting the Fördergutbehälter 2) and in a conveyor section 80c downstream arranged conveying section 80b (for transporting the Fördergutbehälter 2) by a frictional drive (drive device).
On the other hand, the transport carriers 6 can also be moved in the upstream-arranged conveyor section 80a (for transporting the conveyable containers 2) and in the downstream-arranged conveyor section 80b (for transporting the conveyable containers 2) through a form-locking drive (drive device). In this case, a subsequent described and arranged in the conveyor section 80c guide rail 90 can be omitted.
N2019 / 00100-AT-00/93
The conveyor section 80c forms parallel to the longitudinal extent of the overhead conveyor 1 and along the removal station 4 'from a transport path 82 along which the Fördergutbehälter 2, in particular isolated, are transported.
The drive devices described are by no means to be understood as limiting, but merely show different possibilities as to how a drive force is transmitted to the transport carriers 6 or the conveyable containers 2 in order to move them on the overhead conveyor 1 in the transport direction 3 (driven).
If the drive device 5 is formed by a friction drive, it is advantageous if the guide device 81 in the conveying section 80c has a parallel to the transport direction 3 guide rail 90 through which the transport carrier 6 is lifted in the direction perpendicular to and from the friction belt 10, such as shown in particular in FIGS. 13 and 22. This ensures that the Fördergutbehälter 2 is moved in the conveying section 80c exclusively by a positive drive and during the unloading of the transport carrier 6 with the preferably continuously operated friction belt 10 is not in frictional engagement, so that the wear on the transport carrier 6 is kept low. Moreover, it is advantageous that the transport carrier 6 is supported in the ready position 58 and unloading position 59 of the conveyable container 2 on the guide rail 90 and thus the discharge process can be carried out particularly reliable, as shown in Fig. 21a and 21b.
If, on the other hand, this guide rail 90 is not provided in the conveying section 80c, the conveying goods container 2 can in principle also be moved in the conveying section 80c by a frictional and positive-locking drive.
According to a possible embodiment, the drive device 5 in the conveying section 80c comprises a feed drive 83, as shown in more detail in FIG. The feed drive 83 comprises a support frame 84, a traction mechanism drive mounted on the support frame 84 and a driver finger arranged with a traction means 85 for driving movement of the transport carrier 6 or conveying goods container

The drive wheel 87 is coupled to a drive motor 89. Also, the feed drive 83 may include a sensor 74, for example a proximity sensor, by which the supply position 59 is monitored.
The driver finger is moved by the traction mechanism drive between a withdrawn from the transport path 82 starting position and in the transport path 82 engagement position, wherein the driver finger in the engaged position with the Fördergutbehälter 2 in a form-locking engagement and through which the Fördergutbehälter 2 along the conveyor section 81c is movable.
As can be seen in FIGS. 16 and 23, the driver finger may comprise a first driver finger 86-1 and a second driver finger 86-2, which are arranged in the direction of rotation of the traction means 85 at a distance which is determined such that the plurality of driver fingers 86 -1, 86-2 are alternately moved into the engagement position, wherein the respective driver fingers 86-1, 862 in the engaged position with the Fördergutbehälter 2 can be brought into a positive engagement and through which the Fördergutbehälter 2 along the conveying section 81c is movable. 16 shows the driver finger 86-1 in the engaged position and FIG. 23 shows the driver finger 86-1 in the starting position.
The first driver finger 86-1 is engageable with a first Fördergutbehälter 2 in a positive engagement and moves the first Fördergutbehälter 2 along the conveyor section 81c, see Fig. 16 and 17. The second driver finger is engageable with a second Fördergutbehälter 2 in a positive engagement and moves the second Fördergutbehälter 2 along the conveyor section 81c. Although the first conveyed goods container 2 and the second conveyed goods container 2 are transported consecutively through the conveying section 81c, as soon as the first conveyed goods container 2 is transported away from the conveying section 81c by the first entrainment finger 86-1, the second conveying goods container 2 has already been moved through the second entrainment finger 86c. 2 are taken.
N2019 / 00100-AT-00/93
Although two driving fingers are described according to this embodiment, the number of driving fingers may vary. It can also be provided more than two driver fingers. Also, a single driver finger is conceivable.

The stopper elements 93 are by a drive 94 between a retracted from the transport path 82 release position (FIGS. 15, 16 ) and a projecting into the transport path 82 engagement position (Fig. 13, 14) movable.
The stopper elements 93 are designed as stopper fingers or stopper plates. As can be seen in the figures, the stopper elements 93 are each coupled to a drive 94. The stopper elements 93 can be pivoted, for example, by the drive 94 about a vertical axis. But the stopper elements 93 can also be designed as perpendicular to the vertical plane 92 and by drives to each other zubewegbare and movable away from each other stopper plates, as not shown in detail.
The positioning of the Fördergutbehälters 2 against the stopper elements 93 can be performed such that the Fördergutbehälter 2 with one of these having frame 20, with which the bag body between the closed position and the open position is switchable, and / or moved with a bag body against the in the engaged position Stopper finger 93 is positioned.
N2019 / 00100-AT-00/93
If the stopper fingers are in the engaged position, then a (preferably) occasionally transported conveyed container 2 can be positioned against the stopper fingers.
The conveyable container 2 is now in a transfer position (FIG. 14), in which the feed drive 83 described above with the driver finger 86-1 grip the conveyable container 2 and through which the conveyable container 2 moves from the transfer position into a supply position 58 provided downstream thereof. Fig. 17) can be moved. Specifically, the transport carrier 6 is driven by the provided in the conveyor section 80a drive device 5 and thus the Fördergutbehälter 2 positioned against the stopper elements 93 moved into the engaged position. In the illustrated embodiment, the transport carrier 6 is driven in the conveying section 80a by the endless peripheral friction belt 10.
After the unloading process (tilting back of the conveyable goods container 2 from the unloading position 59 into the ready position 58), the conveyable goods container 2 can be moved by the feed drive 83 with the driver finger 86-1 from the supply position 58 (FIG. 17) into a transfer position (see FIG. Fig. 20) are moved, at which the Fördergutbehälter 2 enters the conveying section 80b. Specifically, the transport carrier 6 is driven by the provided in the conveyor section 80b drive device 5 and thus the Fördergutbehälter 2 removed from the unloading station 4 '. In the illustrated embodiment, the transport carrier 6 is driven in the conveyor section 80b by the endless peripheral friction belt 10.
It should be noted at this point that in FIG. 18, for reasons of a better overview, the driver fingers 86-1, 86-2 are not registered. In fact, these are in the positions, as shown in Fig. 17, but due to the tilting movement of the feed drive 83 in a tilted position.
As not shown in more detail, the unloading station 4 'can also have the above-described locking device 70 for locking the transport carrier 6 during a discharging process of the conveyed goods container 2.
N2019 / 00100-AT-00/93
The locking device 70 comprises for locking the transport carrier 6 by means of a drive 71 between an inoperative starting position and an operative operating position movable locking member 72. The locking member 72 includes, for example, a stop against which the moving by the feed drive 83 transport carrier 6 runs and through which the transport carrier 6 is positioned in the transport direction 3. The transport carrier 6 is now positioned between the driver fingers 86-1 arranged upstream of the transport carrier 6 and the arresting element 72 arranged downstream of the transport carrier 6. The conveyable container 2 is now in the ready position 58 (FIG. 17), in which the transport carrier 6 is locked. The provisioning position 58 is monitored via the sensor system 74 shown in FIG. 23, for example a proximity sensor. "Locking" in this context is to be understood such that the transport carrier 6 need not necessarily be fixed in the ready position 58, but also between the driver finger 86-1 and locking member 72 can be moved to a limited extent. Nevertheless, a sufficient positioning between the driving finger 86-1 and locking member 72 is given and it can be reliably carried out the unloading even with highly dynamic tilting movements.
The conveyed goods container positioning device 91 can also comprise guide walls 96 arranged on both sides of the transport path 82 and symmetrically with respect to a vertical plane 92 extending in the direction of the transport path 82.
The guide walls 96 form symmetrically with respect to the extending in the direction of the transport path 82 vertical plane 92 and in the direction of the opening and closing device 40; 53 inclined converging inlet slopes 97 out.

N2019 / 00100-AT-00/93
The bag body is not necessarily already completely converted to the open position.
The driver mechanism 98 preferably comprises a first driver mechanism and a second driver mechanism, which are arranged on both sides of the transport path 82 and symmetrical to a vertical plane 92 extending in the direction of the transport path 82, and which each have an inclined guide slot 99 which can be brought into abutting contact with the frame 20 form, as shown in Fig. 16 can be seen.
The unloading station 4 'may additionally comprise below the unloading position (or picking position) a filling device 100, through which in a first step i) the conveyed material 28 dropped from the product container 2 is received and in a second step ii) the product 28 is conveyed to a receptacle 101 is given, see in particular Figs. 21a, 21b, 21c. The receptacle 101 can be formed, for example, by a container which is transported by a below the filling 100 (only in Figs. 21a, 21b, 21c shown) conveying device 102 transported to a filling position and removed after filling from the filling position.
The filling device 100 comprises a storage shelf 103 and a bottom opening 104 which can be opened and closed by the storage shelf 103. The storage shelf 103 comprises, for example, counter-pivoting floor parts (as is clearly visible in FIG. 19) about axes aligned transversely to the transport direction 3.
Due to the tilting movement of the conveyable container 2, the conveyed material 28 slides on the floor 35 in the direction of the discharge opening 29 and then falls at an angle "a" of less than 60 °, in particular at an angle "a" between 30 ° and 45 ° with respect to a horizontal plane on the storage tray 103 of the filling device 100, as shown in Fig. 21b. The angle "a" results from the tilt angle of the Fördergutbehälters 2 when it is tilted into the unloading position 59.
N2019 / 00100-AT-00/93
With respect to the method for unloading a conveyed material 28 from a conveyed container 2, reference is made to the above disclosure. The various method steps can be understood from FIGS. 13 to 20, 21 a, 21 b and 21 c.
