    BACKGROUND OF THE INVENTION
    The invention relates to a belt conveyor which is provided with a so-called shooting belt for delivering products supplied over the conveyor belt to a further conveyor.
    A firing belt forms a delivery path of the conveyor belt and comprises an end roller at the downstream end of the conveyor belt around which the conveyor belt revolves. This end roll and another bypass roll located upstream thereof are located on a carriage or carriage which is moved back and forth, with the products being brought in the delivery path above the further conveyor and then by a rapid withdrawal of the carriage. as a result of inertia coming loose from the belt in the dispensing path and falling down to the further conveyor, to stack the products on it or to receive it in containers.
    Such arrangements with shooting tape require some space for the conveyor belt in the retracted state of the shooting belt, as well as for the drives. See illustration NL patent 1022737, figure 2. This has consequences for the fall height of the products dispensed. Flexible products, such as meat products, such as meat products and hamburgers, can therefore have the opportunity to tilt during the falling movement, so that they will not always end up at the desired location on the further conveyor belt.
    Conveyor arrangements with shooting belts are furthermore known from, inter alia, DE-GM-8224214 and US 2017/0073104.
    SUMMARY OF THE INVENTION
    An object of the invention is to improve on this.
    It is an object of the invention to provide a conveyor with a firing belt with which the control of the delivery process of the products is promoted.
    From one aspect the invention provides a transport device with
    -a main frame,
    -an endless conveyor belt supported by the main frame,
    -a number of bypass rollers defining the orbit of the conveyor belt, -in which the bypass rollers comprise a first bypass roll that forms an upstream, first end roll and a second bypass roll that forms a downstream, second end roll,
    -a first drive for driving the conveyor belt around the circulating rollers, for transporting products in a first direction, the opposite direction being a second direction, wherein the conveying device has a dispensing path which ends at the second end roll,
    -which the transport device further comprises:
    -an auxiliary frame supported in the main frame on which the second end roll and a third bypass roll is mounted,
    -a second drive for moving the auxiliary frame back and forth in the first and second directions in the manner of a shooting belt relative to the main frame,
    - the conveyor belt forming an open loop in the auxiliary frame, the shape of which is at least partly determined by the second end roll and the third bypass roll, and by above the line that the undersides (of the treads) of the second end roll and the third bypass roll are together connects fourth and fifth circulating rollers, which are arranged in the main frame and which are stationary relative to the auxiliary frame, for circulating the incoming part and the outgoing part of said open loop, respectively.
    Because the open loop located on the back and forth displaced auxiliary frame, which can be retracted by the second drive at relatively high speed in the second direction for fulfilling the function of shooting band, connects upwardly with the connecting trajectories of the circumferential conveyor belt, the space under the auxiliary frame and thus under the delivery path can be at least substantially entirely available for a further conveyor device and any product holders located thereon. These can be situated vertically close to the displacement path of the second end roll, whereby the height of fall of the products in the transition from the dispensing path to the further transport device can remain limited. The open loop can be flat and, in the auxiliary frame in particular, only rotate around the second end roll and the third bypass roll.
    In particular, the fourth and fifth bypass rollers may be located above the line connecting the axes of the second end roll and the third bypass roll, in particular above the line connecting the tops (of the treads) of the second end roll and the third bypass roller are interconnected, more particularly above the profile of the trajectory of the second end roller and third bypass roller when viewed in a vertical plane of projection transversely to the direction of movement of the auxiliary frame. The fourth and fifth bypass rollers can be located above the displacement path of the auxiliary frame.
    In an embodiment in which the clearance of the space below the trajectory path of the auxiliary frame, in particular the second end roller and / or the third circulation roller, is promoted, the first drive comprises a circulation roller which is designed as a drive roller for the conveyor belt, wherein the axis of the drive roller, in particular the entire circumference of the drive roller, is located at a level higher than the profile of the trajectory path of the second end roller and third bypass roller (when viewed in a vertical plane of projection transverse to the direction of movement of the auxiliary frame ), in particular above an infinite horizontal line connecting the tops of the second end roll and the third bypass roll, are located in particular straight above said profile. In one embodiment, all bypass rollers, with the exception of the bypass rollers mounted on the auxiliary frame, with their center line, in particular with their entire circumference, are situated at a level that is higher than the profile of the trajectory of the second end roll and third bypass roll ( when viewed in a vertical plane of projection transverse to the direction of displacement of the auxiliary frame), in particular above an infinite horizontal line connecting the tops of the second end roll and the third bypass roll, in particular straight above said profile .
    All bypass rollers can be located entirely above the line connecting the undersides of the second end roll and the third bypass roll.
    All bypass rollers, with the exception of the bypass rollers mounted on the auxiliary frame, may be located above the profile of the displacement path of the auxiliary frame.
    The belt path extending between the second end roll and the third bypass roll can form the lowest point of the entire belt run
    In one embodiment, the conveyor belt runs from the first end roll in the first direction via the fourth bypass roll to the second end roll, from the second end roll in the second direction, along the bottom, to the third bypass roll and from there in the first direction to the fifth bypass roll and there in an upward direction for the fifth orbit roll to continue in the second direction and eventually arrive at the first final roll.
    In a vertically compact version, the fourth and fifth circulation rollers are on the same level.
    In a further embodiment, the conveying device is provided with a sixth bypass roller, supported in the first direction before the fourth bypass roller (the sixth bypass roller is therefore downstream of the fourth bypass roller), which forms a third end roller which the conveyor belt circulates before passing through an intermediate path in the second direction to reach the fourth bypass roll, the third end roll being located at a level above the displacement path of the second end roll, in particular straight above that displacement path.
    The sixth bypass roll (third end roll) forms the end of a conveyor belt feed path. From there, products can be delivered to the conveyor where it forms the delivery route. The supply route then strengthens between the first final roll and the third final roll. Hereby, with one conveyor belt, a supply path with fixed belt length, on which products can be supplied, and a delivery path formed by a shooting belt, is provided.
    In a version that is compact in the vertical sense, in which the products are disturbed as little as possible, the third end roll is located just above the belt in the delivery route. The third end roll can be held such that the belt running around the third end roll does not touch the belt between the fourth bypass roll and the second end roll. The third end roll can be located with the bottom, in particular with the center line, at a level below the top of the fourth bypass roll, in particular below the center line of the fourth bypass roll. The third end roll may have a diameter smaller than that of the fourth bypass roll and with the top located at a level below the top of the fourth bypass roll,
    For facilitating maintenance work, the third end roll can be arranged on a holder pivotable between a position in which the third end roll is in working position, and a maintenance position pivoted upstream side, the holder being pivotable for this purpose about a horizontal axis transverse to the transport direction and is located on the upstream side of the center line of the third end roll. This provides in a simple manner access to the fourth and / or fifth circulating rollers, which in an embodiment with ends are rotatably supported in lower ends of upwardly extending grooves in the main frame and / or to the auxiliary frame. In the pivoted maintenance position, the center line of the third end roller can be located behind, i.e. upstream of the pivot center line, and then rest against a stop. .
    In this case it is advantageous if said center of gravity is situated at a distance from the second end roll of the transport device that is larger than that for the circumference of the fourth and / or fifth bypass roll.
    In one embodiment the transport device is provided with a control for driving the first and the second drives such that the belt speed corresponds to the speed of the displacement of the auxiliary frame in downstream (first) direction. The transition of products from the supply process to the delivery process is thereby eased.
    From a further aspect the invention provides a transport device with
    -a main frame,
    -a supply device supported by the main frame with a supply path with a supply belt conveyor for transporting products from an input where a first end roll for the belt conveyor is located,
    a dispensing device supported by the main frame with a dispensing path with a dispensing belt conveyor for dispensing the products at a dispensing end, where a second end roll for the dispensing belt conveyor is located, the dispensing apparatus comprising an auxiliary frame which is in a displacement path is movable to and fro with respect to the main frame in the manner of a shooting belt for delivering the products in a downward movement downwardly, such as to a further conveyor device located on a lower conveyor path, the conveyor belt conveyor and the conveyor belt conveyor being designed are endless, endless conveyor belt running around the same number of bypass rollers, the supply path and the delivery path, the transport apparatus further comprising
    -a first drive for all-round driving of the endless conveyor belt and
    a second drive for moving the auxiliary frame to and fro, the supply path terminating at the location of a bypass roll, which forms a third end roll, which third end roll is located above the dispensing path.
    Hereby, with one conveyor belt, a supply path of fixed belt length, on which products can be supplied, and a delivery path formed by a shooting belt, is provided, wherein the space below the shooting belt is at least largely available for other devices.
    In one embodiment, the conveyor belt forms an open loop, in particular a flat, open loop in the auxiliary frame, the shape of which is at least partly determined by the second end roll and a third bypass roll, and by above the line which the undersides of the second end roll and connects the third bypass roller, in particular above the above-mentioned profile of the trajectory path of the second end roller and third bypass roller, mounted in the main frame, fourth and fifth bypass rollers, which are stationary relative to the auxiliary frame, for circulating the incoming and respectively part and the outgoing part of the loop, wherein the fourth and fifth bypass rollers are located at a horizontal distance from the second end roll that is greater than that of the third end roll to the second end roll.
    In one embodiment, the first drive comprises a bypass roller which is designed as a drive roller for the conveyor belt, the axis of the drive roller, in particular the entire circumference of the drive roller, being located at a level higher than the aforementioned profile of the trajectory path of the second end roll and third bypass roll, in particular above an infinite horizontal line connecting the tops of the second end roll and the third bypass roll, are located in particular straight above the trajectory path of the auxiliary frame, seen in side view.
    In one embodiment, all bypass rollers, with the exception of the bypass rollers mounted on the auxiliary frame, with their center line, in particular with their entire circumference, are located at a level higher than the above-mentioned profile of the trajectory of the second end roll and third bypass roll , in particular above an infinite horizontal line connecting the tops of the second end roll and the third bypass roll, are located in particular straight above the trajectory path of the auxiliary frame, seen in side view.
    From a further aspect the invention provides a transport device with
    -a main frame,
    -an endless conveyor belt supported by the main frame,
    -a number of bypass rollers over which the conveyor belt revolves, including a first, upstream end roll,
    -a first drive for driving the conveyor belt around the circulating rollers in conveying direction, the conveying device having a dispensing end with a circulating roller forming a second downstream end roll of the conveying device,
    -an auxiliary frame supported in the main frame on which the second end roll and a third bypass roll are located,
    -a second drive for moving the auxiliary frame back and forth in directions parallel to the transport direction in the manner of a shooting belt relative to the main frame, wherein the first drive comprises a bypass roll designed as a drive roll for the conveyor, the center line of the drive roller, in particular the entire circumference of the drive roller, is located at a level higher than the profile of the trajectory of the end roller and bypass roller included in the auxiliary frame (when viewed in a vertical plane of projection transversely to the direction of movement of the auxiliary frame , in particular above an infinite horizontal line connecting the tops of the second end roll and third bypass roller included in the auxiliary frame, in particular straight above the trajectory path of the auxiliary frame, seen in side view. This promotes the possibility of keeping the space free below the displacement path of the auxiliary frame.
    In one embodiment thereof, the conveyor belt comprises in the circulation a supply path, a delivery path and a return path extending between the delivery path and the delivery path, wherein the delivery path ends at the location of said second end roll, the supply path being located upstream of the delivery path and ends at the location of a bypass roll that forms the downstream (third) end roll of the feed path and is located above the delivery path.
    The circumferential conveyor belt can be seen as comprising two open loops that connect to each other: an (up) open loop on the reciprocating auxiliary frame and a (down) open loop in the relatively stationary main frame.
    The stationary open loop can extend in the first direction over the places of transition between the two open loops, and can be arranged there such that that overlying part can be moved away (such as, for example, the aforementioned holder with third end roll) to make the places of transition accessible and easily remove the fourth and fifth circulation rollers located there. As a result, the freedom in giving a shape to the belt loop is greatly increased, thereby facilitating the removal of the endless conveyor belt. This can then be removed in a direction transverse to the vertical surface of circulation, for cleaning or replacement.
    To facilitate removal of the fourth and fifth bypass rollers, these can be supported with pins or shafts without added fasteners, such as nuts, bolts, on bottoms of vertical grooves open at the top in / on the main frame.
    From a further aspect the invention provides an assembly of a transport device according to any one of the preceding claims and a feed device of product holders, wherein the feed device forms a transport surface for the product holders and is arranged for making the product holders available below the delivery route of the transport device. products supplied over the conveying device over the dispensing path, within the vertical space bounded by the two end positions of the downstream end roll of the conveying device in the reciprocating movement. Hereby, optimum use can be made of the free space below the shooting range, whereby the fall height can be minimal.
    The feeding device can extend along the conveyor belt and feed the product holders parallel to the reciprocating movement of the auxiliary frame, in particular in the first direction, wherein the space requirement can be limited in a horizontal sense.
    Thus, a method for operating said assembly can be provided wherein the downstream end roll of the conveyor is located at a vertical distance from the conveying surface of the feed device which is between approximately 0.5 to approximately 2 times the height of the product holders.

These individual aspects can be the subject of split-off patent applications that are aimed at this. This applies in particular to the measures and aspects that are described per se in the subclaims.

    Figures 3A and 3B illustrate the removal of the conveyor belt in an example of a device according to the invention.
    DETAILED DESCRIPTION OF THE DRAWINGS
    Figure 1A shows diagrammatically an example of a conveyor device 1 according to the invention, with a main frame 2 supported on a floor, in which a conveyor belt 4 which is continuously driven by a first drive, motor 3 with drive roller 3a, is supported. The conveyor belt 4 rotates in directions A1 (top), A2 (bottom), bypass rollers 5,6,7,8,9, drive roller 3a, bypass rollers 11,12 and 13. The bypass rollers 5-9 and 12 are return rollers where the the course of the tire by at least almost 180 degrees. All bypass rollers, except drive roller 3a, are free-running.
    The bypass roll 12 forms a first end roll, which is mounted on a belt tension unit 20, at the feed end. The bypass roll 7 forms a second end roll at the dispensing end. The relatively thin circulating rollers 7 and 8 (third circulating roller) are mounted on an auxiliary frame or carriage 19 (Fig. 1C), which can be moved back and forth in the main frame by a second drive arranged in the main frame, motor 15 (Fig. 1B). first and second directions B1, B2. The carriage 19 is guided on each side by two sliding pieces 22 on sliding rods 23. The carriage 19 is connected on both sides via connections 18 to toothed belts 17 located on either side, which rotate about transverse axes 16a, 16b, the transverse axis 16a being driven by the reversible motor 15. The motor 15 is controllable for imposing a high speed on the carriage 19 in the second direction B2, as is known from shooting tires.
    The motors 3 and 15 are driven by a programmable control unit 30 with processor, in which also data concerning the positions of products and holders are processed.
    The (sixth) bypass roller 5 is also thin and is arranged on the end of a holder 14, which is pivotally arranged in the main frame in directions C1, C2, pivotable about a horizontal axis 21, between an operating position and a maintenance position shown in striped, wherein the tire is relaxed, slack and the stationary (fourth and fifth) bypass rollers 6 and 9 are accessible from above for the fitter. The bypass rollers 6 and 9 are freely rotatably supported with shafts on bottoms of (not shown) vertical grooves open at the top end (see Figure 3B, grooves 31, 32 and bottoms 31a, 32a), so that they can be easily removed. In the maintenance position the holder 14 can rest against a stop.
    The following can be distinguished in the course of the band 4:
    a feed path 4a extending between the first end roll 12 and the bypass roll 5, which then forms a third end roll;
    -a short intermediate trajectory between the end roll 5 and the (fourth) bypass roll 6; a delivery path 4b between the bypass roll 6 and the second end roll 7;
    a first return path 4c between the second end roll 7 and the (fifth) bypass roll 9, via (third) bypass roll 8; and
    a second return path 4d between the bypass roll 9 and the first end roll 12, the belt running around / along the drive roll 3a to be driven thereby. The supply route, the short intermediate route and the second return route are stationary in relation to the main frame (apart from the moving belt). The delivery path and the first return path move with the carriage 19.
    Thus, the band between the bypass rollers 6 and 9, with trajectories 4b and 4c, forms an open loop (due to the non-coincidence of the bypass rollers 6 and 9). The belt 4 forms a run-in part with the circulating roller 6 and an outgoing part of the loop with the circulating roller 9. Because the incoming and outgoing sections of this open loop are located on the top of the open loop, the first return path, between the rollers 7 and 8, can form a lowest point of the circulation of the belt 4. The supply path 4a, the intermediate path and the second return path 4d also form an open loop, the opening of which is situated on the underside thereof.
    The bypass rollers 6 and 9 lie horizontally next to each other, at the shortest possible distance. The circulation roller 9, viewed downstream, lies slightly in front of the circulation roller 8 in the furthest position of the carriage 19 (Fig. 1A). The bypass roll 6 can be located close to the third end roll 5, but in order to keep the distance between the end roll 5 and the belt section 4b as small as possible, the bypass roll 6 is slightly back (in the upstream direction) so that the holder 14 with end roll 5 is inclined can extend downwardly over the bypass roller 6, in the downstream direction.
    In the side views of figures 1A and 2A it can be seen that all the circulation rollers, with the exception of the circulation rollers 7 and 8 mounted on the auxiliary frame, but including the drive roller 3a, are at a level higher than that of the displacement path of the rollers 7 and 8 and of the carriage 19. In the example, these circulating rollers lie above the vertical profile of the displacement path of the second end roller 7 and third circulating roller 8 (when viewed in a vertical plane of projection transversely to the directions B1, 2), in the particularly above an infinite horizontal line connecting the tops (of the circumference in engagement with the belt) of the rollers 7 and 8. They also lie above the trajectory path of the auxiliary frame, viewed in side view of figures 1A and 2A, when combined. As a result, the length of the conveying device 1 is kept limited, because not much more than the distance between the circulating roller 7 in the expanded position (Fig. 1A) and the circulating roller 8 in the retracted position (Fig. 2A) of the carriage 19. Further much vertical space H (Fig. 1A) is available under the belt loop, because the return path 4c determines the lowest level of the belt loop.
    As a result, it is possible to place a feed conveyor 101, which forms an assembly 100 with the conveyor device 1, under the belt 4, for feeding containers 103 with feed belt 102 in a direction D, parallel to the first direction B1. The supply belt 102 can in this case be brought vertically to very close to the underside of the belt 4c, so that the height of fall of the products in the transition from the belt in the dispensing path 4b to the bottom of the holders 103 can be as small as possible. This is conducive to realizing the desired position of the products in the holders 103. The holders 103 can come from a forming device located upstream of the supply belt 102, such as a vacuum forming machine.
    In operation, products P, such as sliced meats or hamburgers, are supplied in the direction E and are transported over the supply path 4a, in the first direction B1, to the third end roll 5, at speed V1. The products P run from this and end up on the belt 4 on the delivery route 4b. The carriage 19 is thereby operated to move from the retracted position of Figure 2A, B to the expanded position of Figure 1A, B. Because the carriage 19 is thereby moved in the direction B1 by the second motor 15 at the same speed V1, the products P can, as it were, lie on the belt 4.
    In the meantime, box-shaped containers 103 are supplied on the feed conveyor 102 to a position below the dispensing path 4b in the extreme expanded position of Figure 1A and held therein. When the slide 19 has then reached the extreme position of figure 1A, the second motor 15 is operated to retract the slide 19 at high speed V2, direction B2. As is known per se from target belts, the products P then remain behind, and due to the absence of a support they will fall into the stand-by holders 102. Because the fall height can be small, the products hardly have an opportunity to change their shape and / or orientation. under the influence of gravity and friction with the retracting belt 4. The filled containers 103 are transported further in the direction G
    During the rapid retracting movement of the carriage 19, care is taken that no products come over the third end roll 5.
    The belt 4 can be continuously driven by the motor 3 and drive roller 3a at speed V1.
    When it is desired to clean or replace the belt 4, it is possible to proceed as indicated in figures 3A and 3B. This diagrammatically shows that the main frame carries a long case 60, it being understood that this case, in the given side view, is actually in front of the belt circulation. However, for reasons of illustration, the band 4 is drawn as a continuous line. Viewed in the first direction F1, the cabinet 60 is then on the left-hand side of the device 1. A superstructure 61 on the main frame is then on the right-hand side. The motors 3 and 15 are also located on that side. The box 60 is releasably coupled to a part of the main frame 2 at the downstream end by means of a locking pin 51. This locking pin can be released by slide 50.
    The auxiliary frame 19 can be stopped in the expanded position, just like the belt circulation by motor 3. Then the support 14 is swung upwards in the direction C1, as described earlier, and then the situation of figure 3A is obtained. The fourth bypass roller 6 can be grasped and lifted out of the groove 31 in the direction M with the end pins. After temporarily bending a belt portion to the side, this can also be done for the fifth circulation roller 9, direction N. Upstream, the circulation roller 10 (direction K) is removed, after which the belt 4 can hang downwards, in the path between the first end roller 12 and high-standing end roll 5 and in the subsequent path between the end roll 5 and the second end roll 7. The slide 50 can then be retracted and thus the locking pin, direction L.
    Subsequently, the belt 4 can be brought into a wide form 4 '(shown in striped form in Fig. 3B), see inter alia direction Q, which makes it possible to remove the belt in the transverse direction R from the device 1, along the downstream end and along the upstream end.
    The invention (s) is / are in no way limited to the embodiments shown and described in the drawings and description. The above description is included to illustrate the operation of preferred embodiments of the invention, and not to limit the scope of the invention. Starting from the above explanation, many variations will be apparent to those skilled in the art that fall within the spirit and scope of the present invention. Variations are possible of the parts shown in the drawings and described in the description. They can be used separately in other embodiments of the invention (s). Parts of different examples can be combined with each other.
