Module for the individual transport of fruit and vegetables
The present invention relates to a module for the individual transport of vegetables and fruit, and a transport installation comprising at least one of these modules.
A prior art transport installation for fruit and vegetables comprises an endless chain on which pairs of truncated cones are attached at regular intervals. The endless chain moves in a general direction of movement between a drop zone and a distribution zone.
The truncated cones of a pair are arranged on the one hand so that the small bases of each of them are opposite each other and, on the other hand, coaxial to each other.
In addition, the axis of the truncated cones is perpendicular to the general direction of movement.
This creates an individual space for a piece of fruit or vegetable between two consecutive truncated pairs.
In the market zone, the vegetables and fruit are separated and placed in an individual room. The distribution zone has different collection zones and each piece of fruit is ejected into one of the collection zones on the basis of one or more characteristics.
Such a transport installation does not give complete satisfaction because it is sometimes necessary to change the distance between two consecutive truncated cone pairs on the basis of the transported vegetables or fruit. Due to the complex nature of the transport installation, this change is difficult to implement.
Moreover, the ejection of fruit and vegetables, which usually takes place laterally with respect to the general direction of movement, is difficult due to the fact that it is necessary to bridge the rising sloping surface created by the two consecutive truncated cones.
A subject of this invention is to propose a module for the individual transport of fruit and vegetables which does not have the disadvantages of the previous technique and which is, in particular, easy to use and allows great flexibility regarding the type of fruit or vegetables that are trans- can be ported.
To this end, a module for the individual transport of fruit and vegetables is proposed which is attached to a chain moving in a general direction. The module includes; - a base to be fastened to said chain, - at least one tiltable support structure mounted for pivotal rotation on the base about an axis of rotation that is largely horizontal, and parallel to the general direction of movement, said tiltable support structure between a transport position of the vegetable or fruit and an ejection position of the vegetable or fruit moves, for the, or each tiltable, support structure - two rotating parts that are mounted for mobile rotation about their rotational axes that are parallel to the general direction of movement and between them have room for the fruit, and - wherein at least one of the two rotating parts is mounted on the tiltable support structure, wherein the module has the feature that the base comprises a first part that is coupled to the chain and a second part that rotates freely mounted on said first part and that said tilt The pivotable support structure is freely rotatably mounted on the said first part and the said pivotable support structure is freely pivotably mounted on the said second part. The advantage is that the pivotable support structure has sled forming means for each rotating part of the revolution in which the associated pivoting means part is placed.
The advantage is that the said slide forming means are suitable such that the said rotating parts are displaced in a V-shape.
The advantage is that the slide forming means are boring holes that are made in the tiltable support structure and are aligned such that their longest axes form a V.
The advantage is that each rotating part takes the form of a truncated cone pair.
The advantage is that the truncated cones of said pair are arranged coaxially with respect to each other and that the small bases of each truncated cone of said pair are arranged opposite each other.
The advantage is that each truncated cone pair consists of a central, one-piece part and two outer parts, the central part taking the form of two cones whose small bases are opposite each other, and each outer part taking the form of a wheel with a truncated cone profile.
The advantage is that each outer part and the central part have coupling means intended for connecting the rotating outer parts and connecting them to the central part.
The advantage is that said tiltable support structure comprises a secondary element, a low edge at the free end of the tiltable support structure, and a high edge that is substantially perpendicular to the axis of rotation.
The advantage is that the two edges have a V-configuration.
The invention also proposes a transport installation comprising the following: - an endless chain that circulates between an outlet zone and a number of collection zones, - at least one transport module according to one of the previous variants which is mounted on said chain at the end, instruments for registering the characteristics of the vegetable / fruit that is placed on the, or on each transport module, - at least one drive device intended to rotate the two rotating parts of the, or of each transport module, around their axis of rotation, - an analysis instrument intended to analyze the characteristics that the recording instruments have recorded, - tilting instruments that are controlled by the analysis instrument and are intended to make the tiltable support structure move from the transport position of the vegetable / fruit to the ejection position of the vegetable / fruit in the catch zone corresponding to the analysis results.
The advantage is that the drive device has at least one cylindrical roller that revolves around the axis that runs parallel to the general direction of displacement.
The advantage is that the end of the roller where the rotating parts arrive will become wider as it proceeds in the direction of the movement of the transport modules.
The above-mentioned features of the invention, and others, will become more apparent upon reading the following description of an exemplary embodiment wherein said description is made on the basis of the accompanying drawings, including:
FIG. 1 represents a transport installation of vegetables and fruit according to the invention,
FIG. 2 a transport module for the transport installation of fig. 1 when the vegetable or fruit has been analyzed,
FIG. 3 represents the transport module if the vegetable or fruit has been ejected,
FIG. 4 is a front view of the transport module according to the invention,
FIG. 5 is a side view of the transport module according to the invention, and
FIG. 6 is an exploded view of the transport module according to the invention.
In the following description, the terms relating to a position refer to a transport module arranged for transporting a piece of vegetable or fruit, i.e. as it is shown in Fig. 1, i.e. in a transport position of the vegetable or the fruit.
The description is more particularly based on the transport of a piece of fruit, but it also applies to a vegetable.
FIG. 1 shows a transport installation 100 for transporting pieces of fruit F between a delivery zone and a distribution zone. The delivery zone is the zone where the pieces of fruit F are placed one after the other and individually on the conveyor 100 by a fruit supply system, for example of the conveyor belt type. The distribution zone has a number of collection zones and each piece of fruit is ejected to one of the collection zones according to one or more characteristics. An analysis zone is provided between the outlet and the collection zone where the characteristics of each piece of fruit F are analyzed (color, weight, diameter, errors, ...).
The conveying installation 100 comprises: - an endless chain 102 that circulates between the delivery zone and different collection zones, and - at least one conveying module 106 mounted on said endless chain 102 and serves to collect a piece of fruit F individually.
The chain 102 is furthermore driven by a drive device (not shown).
Between the outlet zone and the distribution zone, the endless chain 102 forms a loop and moves in a general direction of movement 104.
The transport module 106 comprises: - a base 108 for securing said transport module 106 to the endless end chain, - a tiltable support structure 110 mounted for rotation on the base 108, about a substantially horizontal axis of rotation 113, and parallel to the general axis of rotation direction of movement 104 because said tiltable support structure 110 moves between a transport position of the fruit F and an ejection position of the fruit F, and - two rotating parts 116a, 118a, and 116b (not shown in FIG. 1), 118b mobile pivotally mounted about their axis of rotation parallel to the general direction of the displacement 104 and having a space 120 therebetween for receiving the fruit F, at least one of the two rotating parts 116a, 118a, or 116b, 118b is thereby the tiltable support structure 110 mounted.
In the embodiment of the invention shown in the figures, the two rotating parts 116a, 118a, and 116b, 118b are mounted on the tiltable support structure 110, but it is possible to provide that only one of them is mounted on the tiltable support structure 110 is mounted.
The piece of fruit F is then discharged on the side where the tiltable support structure 110 tilts.
Such a transport module 106 is particularly suitable for long pieces of fruit F such as pears.
The tiltable support structure 110 comprises a hull 114 which is mounted for rotation on the base 108.
Each rotating part 116a, 118a, 116b, 118b here takes the form of a pair of truncated cones.
For each pair, the truncated cones 116a, 118a, 116b, and 118b are arranged coaxially with respect to each other, and the small bases of each truncated cone 116a, 118a, 116b, and 118b, are opposed to each other.
The two pairs of truncated cones 116a and 118a, and 116b and 118b are placed side by side, which means that their rotational axes have a horizontal distance that is not zero.
In the embodiment of the invention shown in FIG. 1, the base 108 has mounting means 124 which are provided for mounting the conveyor module 106 on the endless chain 102.
As can be better seen in Fig. 4, the fastening means 124 here take the form of two bars 412, only one of which is visible, and which originate from the element of the base 108, a clamping plate 128 which connects to said bars 412 and for each bar 412 a clamping nut 414 that is screwed onto the free end of the bar 412
The chain 102 is thus pressed between the base element 108 and the clamping plate 128.
In another embodiment of the invention, not shown, the fastening means 124 may look like elastic parts of the pinch type that form a spring.
The axis of rotation 113 extends above the chain 102 and beyond. The tiltable support structure 110 extends over a horizontal plane parallel to the general direction of the displacement 104 and on the same side of the chain 102 as the axis of rotation 113 which facilitates the ejection of the fruit F far from the endless chain 1G2, such as explained below.
Each transport module 106 forms a unit that can be easily changed if it is defective or if the size of the fruit F requires a more or less large distance between the two rotation axes of the truncated cone pairs 116a and 118a, and 116b and 118b '.
FIG. 2 shows the transport module 106 in the analysis phase. To this end, the transport installation 100 comprises recording instruments which are intended to record the characteristics of the fruit F and at least one drive device 202. The recording instruments can be, for example, a camera, a scale, ...
The drive device 202 is here a cylindrical roller that is rotated (arrow 206) about its central axis 204 parallel to the general direction of the displacement 104. To this end, a drive means, for example of the type of an electric motor, causes roller 202 to rotate,
The drive device 202 is intended to cause the two pairs of truncated cones 116a, 118a and 116b, 118b of each module 106 to rotate about their axis of rotation.
The two pairs of truncated cones 116a, 116b, 118a and 118b rest on the circumference of the roller 202 and the rotation of said roller 202 causes the rotation of the truncated cones 116a, 116b, 118a and 118b and consequently the rotation of the fruit F among the recording instruments. The characteristics of the largest surface of the piece of fruit F can thus be recorded by the recording instruments and analyzed by a suitable analysis instrument of the conveyor 100, such as an analysis unit of the color of the piece of fruit F.
To facilitate the rise of the truncated cones 116a, 116b, 118a, and 118b on the roller 202, the end of roller 202 where the truncated cones 116a, 116b arrive becomes wider as the progression of the transport module 106 progresses further. the general direction of movement 104 follows.
The truncated cones 116a, 116b, 118a and 118b will thus effectively rest on roll 202 and thus be made to rotate.
The drive device 202 can be a plurality of rollers that follow one another along chain 102 and are turned in opposite directions to loosen the pieces of fruit F that are stuck.
FIG. 3 shows the transport module 106 in the ejection position of the fruit F, that is, when the tiltable support structure 110 is in ejection position.
On the basis of the characteristics, for example the color, the piece of fruit F is ejected to a suitable receiving zone.
The transport installation 100 for this purpose comprises tilting instruments which are controlled by the analysis instrument and which are intended to make the tiltable support structure 110 move from the transport position of the fruit / vegetable to the ejection position of the fruit / vegetable in the receiving zone which corresponds to the analysis result,
In the embodiment of the invention shown in the figure, the module 106 includes a blocking device 112 mounted on the base 108 and is intended to alternately assume a locking position in which it locks the tiltable support structure 110 in the transport position and a unlocking position in which he frees the tiltable support structure 110 that tilts into ejector position.
The tilting instruments can then, for example, take the form of a number of fingers controlled by the analysis unit, each finger being provided to operate the blocking device 112 to cause them to move from the locking position to the unlocking position and thus the tiltable support structure 110 if it passes through the appropriate collection zone that matches the analysis results.
In other embodiments of the invention that are not shown, the tilting instruments may take the form of an ejection system that pushes the tiltable support structure 110 out of its equilibrium position, or an alternating position system in combination with a carriage that lifts the tiltable support structure 110.
The tiltable support structure 110 then rotates about the axis of rotation 113 and the piece of fruit F is then ejected under its own weight through the free end of the tiltable support structure 110, whereby the piece of fruit F is removed from the chain 102. The piece of fruit F then falls into the suitable collection zone corresponding to its characteristics.
FIG. 4 shows the transport module 106 in front view, i.e. a view perpendicular to the general direction of the displacement 104.
The main element 114 comprises a secondary element 402 which here takes the form of an arc, a low edge 406 and a high edge 404.
The two edges 404 and 406 are in communication with the secondary element 402 and are V-shaped in the plane perpendicular to the general direction of the displacement 104 to help make the space 120.
The high edge 404 is positioned substantially vertically of the rotation axis 113 and the low edge 406 is placed at the free end of the tiltable support structure 110.
FIG. 5 more particularly shows the blocking device 112 which cooperates with the secondary element 402 via a stop 510 comprising it.
The blocking device 112 comprises an element 502 mounted for mobile rotation about a blocking axis 504 on the base 108, a blocking nose 506 which cooperates with the stop 510, and a handle 508 which must cooperate with the tilting instruments.
The blocking device 112 also includes an elastic reset member which returns the element 502 to the locking position when it is brought into the unlocking position.
When the blocking nose 506 acts on stop 510, the tilting support structure 110 is held in transport position, and when the blocking nose 506 no longer acts on the stop 510, the tilting support structure 110 moves to the ejection position.
FIG. 6 shows an exploded view of a special embodiment of the invention.
The base 108 comprises a first part 604 and a second part 602.
The first part 604 is intended to be connected to the chain 102 and it carries the blocking device 112, the fastening means 124, and the second part 602.
The second part 602 is mounted for free rotation on the first part 604, around a weighing gas, and the tilting support structure 110 is mounted for free rotation on the second part 602. The rotational movements are limited to a limited angle sector,
The connection of the second part 602 to the first part 604 takes place by the attachment of the contact plates 606 of the second part 602 in the boring holes 608 (Fig. 4) of the first part 604. The axis of the contact plate determines the weighing gas running parallel to the general direction of the displacement 104.
The second part 602 carries the tiltable support structure 110 and more particularly the secondary element 402. To this end, the secondary part 402 has two contact plates 610 and the second part 602 has two boring holes 612 provided around said two contact plates 610 via mounting to receive the rotary joint around the axis of rotation 113,
When weighed by placing the secondary element 402 on a scale, the second part 602 plays the role of a rod that prevents the weight measurement from being disturbed by reactions between the base 108 and the tiltable support structure 110.
The low edge 406 here forms one block with the second element 402.
The high edge 404 is mounted on a shaft of the truncated cone pair 116b and 118b by means of a clip 614.
As described below, the pair of truncated cones 116b and 118b, and hence the high edge 404, are mounted movably in translation relative to the secondary element 402.
To limit the linear displacement of the high edge 404, the high edge 404 and the secondary element 402 include means for limiting the linear displacement of the high edge 404 relative to the secondary element 402.
The means for limiting the linear displacement take the form of an arm 616 for the high edge 404 with a boundary block 620 on its free end, and for the secondary part 402 the shape of a slotted hole 618.
Each boundary block 620 fits into a slotted hole 618 of the secondary element 402, and the linear displacement of the high edge 404 is limited by the displacement of the boundary blocks 620 in the slotted holes 618.
In the embodiment of the invention proposed here, each truncated cone pair 116a and 118a, 116b and 118b is formed by a central member 622 and two outer members 624.
The central part 622 forms a one-piece unit which is in the form of two cones whose small bases face each other.
Each outer part 624 has the shape of a wheel with a truncated cone profile, the small base of which is opposite the large base of one of the cones of the central part 622,
The diameter of the small base of the truncated cone of the outer member 624 remains larger or equal to the diameter of the large base of the cone of the central member 622 opposite.
For the connection of the central part 622 and the outer parts 624, they are each provided with connecting means 626, 628, 630, 632 which are intended for rotating connection of the outer parts 624 and to connect them to the central part 622.
The connecting means of each outer member 624 is in the form of a shaft 626 with a flattening 628 and a tongue 630 extending the shaft 626 '. The connecting means of the central part 622 are in the form of a boring hole 632 in D.
module for the individual transport of fruit and vegetables The dimensions of the boring hole in D 632 are such that they cooperate with the flattened parts 628 and thus ensure that the central part 622 rotates simultaneously with the outer parts 624.
The secondary element 402 has two vertical walls opposite each other.
For each truncated cone pair 116a and 118a, 116b and 118b, each wall has a slotted hole 633, 634. For the same truncated cone pair 116a and 118a, 116b and 118b, the slotted holes 633, 634 of the two walls face each other. The assembly is done in the following way: - the central part 622 is placed between the two walls of the secondary element 402 opposite the two slotted holes 633 or 634 corresponding to it, - the shaft 626 of one of the outer parts 624 is successively slotted 633 or 634, then slid into the D-shaped boring hole 632, and the shaft 626 of the other outer part 624 is successively slid into the other slotted hole 634 or 633 and then into the D-shaped boring hole 632.
The shafts 626 are depressed until the tongues 630 face each other on the inside of the D-shaped boring hole 632. The tongues 630 have dimensions such that, when facing each other, they are in contact via one of their faces, and thus a cause radial spread and pressure against the wall of the boring hole 632 of the bayonet pins on the opposite walls.
The slotted holes 633 and 634 of the same wall are oriented such that their longest axes form a V in a plane perpendicular to the general direction of the displacement 104. When the truncated cone pairs 116a and 118a, and 116b and 118b are placed on roll 202 , they aim to ensure good contact with the piece of fruit F so that it can turn properly.
The slotted holes 633 and 634 thus form means that form a slide representing the main element 114 and in which the corresponding truncated cone pair 116a, 118a, 116b, 118b is placed.
The means forming a carriage 633 and 634 are positioned such that a V-shaped displacement of the pairs is ensured.
This invention is of course not limited to the described and illustrated examples and embodiments, but it is suitable for numerous variants which are accessible to those skilled in the art.
For example, the rotating parts are more specifically described in the form of two truncated cones, but they can take on a different shape, such as parts with a hyperbolic profile.
For example, the invention has been described more specifically in the case of a chain forming a vertical loop, but it applies in the same way as the chain forms a horizontal loop.
Thus, the invention has also been described more specifically in the case that only a tiltable support structure is mounted on the base, but it is possible to mount a number on the same base, either on the same side of the chain or on either side of the chain to increase the volume.
In this case, the base 108 carries at least one tiltable support structure 110 and the module 106 comprises two rotating parts 116a, 118a, and 116b, 118b for each of the tiltable support structures 110, one of the two of which is mounted on the corresponding tiltable support structure 110 .
For example, in order to improve the supply of fruit F through the rotating parts, they are equipped with grooves which protrude and come into contact with the fruit F.
