Definitions
- the present invention relates to a method of forming batches of objects, substantially parallelepipedic, circulating continuously on a conveyor belt for feeding, for example, a shrinkwrapper; it also relates to the device for implementing said method.
- the invention relates to the formation of batches of substantially parallelepipedic objects, such as bricks of milk or fruit juice, for packaging by a shrinkwrapper of the type described in FR 2847242, by example.
- this shrinkwrapper must be done with extreme precision, without fail because, after this packaging, the packets are palletized and directed to their place of sale. The slightest incident can have repercussions on a good part of the lots or even the pallet. Or the products of the kind of fruit juice bricks or others are relatively difficult to handle and this especially as sometimes they may include a straw which is directly adhered to a side face of the product.
- the document DE 3825069 describes a conveyor device which makes it possible to separate trays which are in Indian file, with key-touch.
- This separation device comprises a passageway formed by two flaps which are articulated to achieve a temporary deflection of the tray that passes and to direct it to a stop disposed on the side of the conveying path, which stop immobilizes the tray in question for a time sufficient to make a space between the immobilized tray and the previous tray.
- Such a device can operate at relatively high rates to separate trays but it is not suitable for forming, at a high rate, lots consisting of bricks.
- KP 1717170 discloses a palletizing facility which includes a batch preparation device with packets arriving in single file.
- the leader is supported by a stop and, as soon as the number of packets forming the batch is reached, the queue is stopped by a clamp system. During this stop of the queue, the batch is moved transversely to a palletizing table.
- the sequential nature of this type of device can not accommodate the very fast rates that are encountered in batch preparation facilities consisting of products of the brick type.
- the present invention proposes to solve the batch packaging problems of these substantially parallelepipedic objects such as milk bricks, fruit juice or other; it proposes a method and a device for its implementation which allow to operate at a high rate with a maximum of safety and efficiency
- the present invention relates to a method of forming batches of substantially parallelepiped circulating objects aligned and contiguous against each other, in single file, which objects, a length i, are transported by a conveyor belt advancing at a longitudinal velocity Va, which method consists in: immobilizing said file along its length, in a corridor, by means of stop means which act in a sequential manner, to create a space between two consecutive objects and to isolate, downstream of said space, a group of objects which forms the batch with its number of objects as programmed,
- the method of immobilizing the queue consists;
- a safety stop in the form of an abutment for retaining the downstream object which is at the front of the queue.
- the space created between two consecutive objects, when the queue is stopped has a length which is of the order of half the length I of said objects.
- the difference in speed between the conveying belt of the objects and the support cleats of the different sets of objects is of the order of 10 to 15%, with a lower speed for said cleats of objects. to create an interval between batches before presenting them to the shrinkwrapper, for example.
- the cleats support and accompany the batch of objects over a distance which is of the order of 1.5 times the length L of said batch of objects.
- the invention also relates to a device for implementing the method of forming batches from objects which circulate in single file, contiguous to each other, conveyed by the endless belt of a conveyor, which device comprises:
- the immobilization means of the queue consist of:
- the axes of the flaps are offset longitudinally: the axis of the reactive flap is located downstream of the axis of the deviating flap, at a distance which is between the length £ and half of this length of objects said distance being measured on the longitudinal axis of scrolling objects.
- This constructive arrangement makes it possible to deform the corridor by reducing the width of its entry and this deformation is achieved with a relatively modest effort thanks to the leverage effect given to said deflection flap by the position of its hinge axis.
- the deformation of the corridor forms a kind of bottleneck and allows the line to be blocked not at its end, as is generally the case, but upstream of its leadhead; as a result, the contact pressure between the objects is released and the head object can even be almost free.
- the reactive flap retracts, under the effect of the deflector flap, via the objects arranged between the two, which retracting flap, by retracting, releases a safety stop in stop form capable of temporarily holding the upstream object which constitutes the head of the queue.
- the cleats are regularly distributed and carried by a motorized endless chain whose active strand is, on the one hand, parallel to the direction of advancement of the objects and, on the other hand, disposed downstream of the shutter.
- deviator which cleats are spaced a pitch P which is substantially greater than the length L of the batch of objects, of the order of a few millimeters, between 1 and 5 mm depending on the nature of the objects.
- the cleat is associated, on the endless chain, with an actuating member of the deflector flap, which operating member cooperates with a cam-shaped arrangement disposed on said deviation flap so as to as the cleat approaches the latter, the assembly constituted by the roller and the cam makes it possible to coordinate the stop of the line and the passage of the cleat for the insertion of said cleat in the space created between two objects by the immobilization of said queue.
- the reactive flap is counteracted by means of the spring type, which reactive flap performs the automatic replacement of the flap diverter, through said spring, through the objects that flow between the two, when the roller leaves the cam of said deviating flap.
- the length of the deviating flap is, for example, of the order of the length of three to five objects.
- the deflector and reactive flaps and the downstream abutment are arranged on the same structure whose position is longitudinally adjustable relative to the general frame to adapt to changes in the formats of the objects and / or batches to be formed.
- which structure is wedged longitudinally with respect to the position of the upstream guide wheel of the endless chain which carries the rollers and the cleats, said position of this upstream wheel being itself longitudinally adjustable to allow the reception of different models chains whose said cleats and rollers are distributed in a step adapted to the length L of said batches to be prepared.
- FIG. 1 is a perspective view of the device according to the invention for the formation of batches of objects circulating continuously against each other on a conveyor belt;
- FIGS. 2 and 3 are two partial enlarged views of the support assembly of the passage of objects at the exit from which the batches of objects are formed;
- FIGS. 4 and 5 are two views from above respectively illustrating the device according to the invention in an inactive position and in a stop position of the flow of objects for the purpose of forming a batch of objects;
- FIG. 6 is a bottom perspective view of the endless chain assembly of the device according to the invention.
- FIG. 7 shows, in the form of a block diagram, the essential elements of the batch preparation device, - Figures 8 to 12 show different stages of batch preparation according to the method of the invention.
- Figure 1 shows a perspective view of the device 1 according to the invention for the formation of batches of moving objects 2 aligned continuously against each other, in single file, on a conveyor belt 3.
- the objects 2 are fed, by means of known type per se, upstream on the conveyor belt 3 continuously and contiguously following each other in single file.
- the objects 2 to be put in batches, of the food brick type, have a parallelepipedal shape; these objects 2 have a length Z, as shown in FIG. 8, and the batch formed from these objects 2 has a length L, as shown in FIG. 11.
- the device 1 comprises - a support assembly 4 in which is formed a passage 5 for the passage of objects 2 and - an endless chain assembly 6, the functionality of which will be explained later.
- the support assembly 4 consists of a first wall 7 and a second wall 8, parallel to each other, arranged on either side of the conveyor belt 3 and interconnected by a plurality of sleepers 9, provided substantially transverse to the direction of travel of the conveyor belt 3 and corresponding to the direction of the arrow F as illustrated in FIG.
- a lateral plate in the form of a pivoting flap 10 (or lateral leaf), whose pivoting is controlled by the endless chain assembly 6, while on the inner face of the wall 8 , vis-à-vis the flap 10, is also fixed a flap-shaped side plate 11 preferably also provided pivoting.
- deformation of said passageway 5 is effected by displacement, preferably by pivoting of the pivoting lateral flap 10 fixed on the first wall 7, which causes the objects to move on the conveyor belt 3 which then bear on the flap 1 1 fixed side on the second wall 8, thus causing the locking of objects housed between the two flaps 10, 11 side.
- the flap 10 constitutes the deflector flap, that is to say the flap which spreads the objects 2 transversely, and the flap 11 constitutes the reactive flap in the sense that it is maneuvered by said flap by means of said objects 2 and that, as detailed below, it is he, the reactive flap 11, which puts said flap 10 deviator in the inactive position.
- Each flap 10, 11 lateral is fixed on the inner surface of the wall 7, 8 respectively by means of fixing means which consist of axes 12, 13, respectively. These axes 12, 13 are positioned upstream of the flaps 10, 11, respectively, which flaps pivot transversely relative to the direction F of scrolling objects 2 on the conveyor belt 3.
- the entry of the corridor 5 undergoes a narrowing, that is to say a decrease in its width by bringing the two lateral flaps 10, 11 closer together when they are pivoted.
- This narrowing is obtained by an offset of the axes 12, 13, pivoting of the two flaps 10, 11 side, relative to each other in the direction F of scrolling objects 2 on the conveyor belt 3, c ' that is to say that the two pivot axes do not belong to the same plane that is transverse to the direction F of scrolling.
- the axis 12 of the deflecting flap 10 is located upstream of the axis 13 of the reactive flap 11, at a distance which is, for example, between the length j6 and half of this length of the objects 2, said distance being measured on the longitudinal axis of scrolling of said objects.
- a cam 14 for controlling the pivoting of said flap 10 which is fixed on its outer surface 10a (see FIG. 2), that is to say on its surface opposite the surface capable of coming into contact with the objects 2 traveling on the conveyor belt 3.
- the inactive position of the deflector flap is established by a stop 15 which is fixed on the wall 7 as shown in FIGS. 2 to 5.
- the flap 10 is then substantially parallel to the direction F of scrolling objects 2, said objects 2 during their passage in the corridor 5, tending to push out the flaps 10, 11 side, and therefore to come press said flap 10 against the stop 15.
- the stop 15 is made of a plastic or rubbery material, on which is seated the flap 10 deflector.
- the reactive flap 11 attached to the second wall 8 of the support assembly 4 is in turn bearing against spring means 16 capable of exerting a thrust force in a continuous manner on said flap 11, that is to say say able to exert a thrust force substantially transverse to the direction of travel F objects 2 and tending to press said flap 11 against the objects 2 traveling on the conveyor belt 3.
- the cam 14 tends to cause the deviator flap to pivot in the counterclockwise direction (counterclockwise direction), whereas the spring means 16 tend to pivoting the reactive flap 11 in the clockwise direction (clockwise), the cam 14 and the spring means 16 being respectively provided downstream of the pivot axes of the two flaps 10, 11 respectively fixed on the walls 7 , 8 of the set 4 support.
- upstream element an element located or directed upstream of the conveyor belt 3
- downstream element an element located or directed downstream of the conveyor belt 3.
- the conveyor belt 3 runs from an "upstream” element to a "downstream” element.
- the device 1 may have a member 17 for retaining the objects 2 flow, acting as a stop, against which may abut the object 2a is in the lead, as this is shown in Figure 5.
- the body 17 for retaining the flow of objects 2 which is blocked between the flaps 10, 11, is fixed on the same wall 8 as the flap 11 undergoing the thrust force of the means 16 springs.
- the flaps 10, 1 1 block the flow of objects 2 in the corridor 5 without the object 2a blocked further downstream abuts against the flow retaining member 17; the flaps 10, 11, block the queue at the entrance to the corridor 5 through the restriction of the width of this entry.
- the object 2a the further downstream is not sufficiently tight between the two flaps 10, 1 1 and continues to advance by the running movement of the conveyor belt 3 to the retaining member 17.
- the flap 11 has at its downstream end at least one tooth 18, 19 , as represented in FIG. 2, able to pass through openings 20, 21 formed in the retaining member 17 and to move the most downstream object 2a which would have come into abutment against the flow retaining member 17.
- the retaining member 17 is in the form of a U-shaped box consisting, on the one hand, of two walls 23, 24, namely an upstream transverse wall 23 and a downstream transverse wall 24, preferentially fixed by their free end on the second wall 8 of the assembly 4 support, and, secondly, a bottom wall 25 provided substantially parallel to the direction F scrolling.
- the openings 20, 21 provided in the box 22 are advantageously formed in the upstream transverse wall 23, against which an object 2 can be abutted, as well as in the wall 25 so that the teeth 18, 19 are substantially in the same direction. planar said wall 25.
- FIG. 1 One possible form of an embodiment of the spring means 16 is illustrated in FIG. 1
- the means 16 springs consist of a rod 26 passing through the wall 8 and a box 27, also fixed on the outer face of said wall 8 (that is to say the non-directed face to the flow of objects 2 scrolling on the conveyor belt 3), the box 27 being in the general shape of U, with two walls 28, 29 forming the vertical branches of the U and whose ends are directly fixed on the outer surface of the wall 8 and a bottom wall 30 also traversed by the rod 26.
- the rod 26 has a first end 31 of support adapted to come into contact and push against the outer surface of the flap 1 1 fixed on the wall 8.
- a spring 32 is provided wound around the rod 26; this spring 32 is supported, on one side, on a ring 33 which is disposed at the end 31 of the rod 26 and, on the other side, on a washer 34 which is fixed on the inner surface 30a of the bottom wall 30 of the box 27.
- This rod 26 passes through the wall 30 in the middle of the bearing washer 34 and a ring 35 acting as a stop is fixed on the end of the rod 26; this ring 35 abuts on the outer surface 30b of the bottom wall 30, when the flap 11 is substantially parallel to the direction of travel F of the conveyor belt 3 and it departs when said flap 11 is rotated to 2.
- the rod 26 is constantly subjected to a tension tending to increase the eeartment between the bottom wall and the end of the rod 26 resting against the flap 11.
- the spring 32 contracts when said flap 11 is moved due to the pivoting of the deviator flap through the objects 2 which are placed between the two.
- the return movement of the flap 10 is caused by the relaxation of the spring 32 which pushes the flap 11 and, through the objects 2, said flap 10.
- This assembly 6 comprises an endless chain 37 on which is fixed at least one roller 38 capable of cooperating on the cam path formed by the cam 14 fixed on the flap 10, and a cleat 39, which cleat, by example in the form of a wafer, is adapted to be inserted in the gap between two objects 2 flowing on the conveyor belt 3 at the outlet of the passage 5 formed by the two flaps 10, 11.
- the tab 39 is adapted to serve as support for the object 2a further downstream of the flow of objects 2 which has been blocked by the flaps 10, with 1 1 their pivoted position ( see Figure 5).
- the endless chain 37 is engaged on two wheels 40, 41 toothed; at least one of the two wheels 40, 41 is able to be moved in a direction substantially parallel to the direction of travel F objects 2 on the conveyor belt 3.
- This chain 37 without end is placed laterally with respect to the conveyor belt 3 so as to allow the insertion of the cleats 39, fixed on the chain 37, downstream the object 2a furthest downstream of the flow of objects 2 which is blocked by the flaps 10, 11, during the return of these objects 2, 2a on the conveyor belt 3.
- the flaps 10, 11 Due to the transverse shift of the pivot axes, the flaps 10, 11 are no longer parallel to each other during this pivoting movement and they tend to approach and exert a pressure force on both sides of the objects 2 which has the effect to retain and block these objects 2 between the flaps 10, 11, and this despite the movement of movement of the conveyor belt 3.
- the flap 10, approaching the flap 11, is also close to the axis 13 of the latter which has the effect of causing a narrowing at the entrance to the corridor 5 formed by the two flaps 10 and 1 1.
- This closure at the entrance of the corridor 5 allows to modify the pressure that is normally exerted between the different objects 2 in single file; the blocking of the line at the entrance of the corridor 5 releases the pressure between the objects that are in said corridor. Therefore, the object 2a which is in the lead in the corridor 5, is not pressed against the stop 17 by the other objects so that, when the flaps 10 and 11 return to the inactive position, under the effect of means 16 springs, the object 2a is replaced without any difficulty on the longitudinal conveying path.
- the pivoted flap 10 returns to its initial position, that is to say in a position substantially parallel to the running direction of the strip 3 conveying.
- the means 16 springs facilitate the return in place of said flaps 10, 11, said spring means 16 exerting a thrust force directed substantially towards the other of the two flaps 10 , 11 and to the objects 2 conveyed.
- the cleat 39 is advanced in a longitudinal direction, coinciding with the direction of movement F of the objects 2.
- the speed Vt of advancement of the cleat 39 is, for this purpose, slightly less than the speed Va of travel of the conveyor belt 3.
- the cycle starts again, sequentially; again the deviator flap pivots, which makes it possible to form another batch of objects 2 which is in turn retained by the cleat 39, which batch comprises a number of objects 2 which corresponds to the number of objects released on the conveyor belt 3 between two successive steps of blocking the line by the flaps 10, 11.
- the step of displacement preferably by pivoting of the deflector flap derives from the contacting of the roller 38 on the cam 14 fixed on the deviating flap, and, more precisely, the contacting step of the roller 38 as well as the step of inserting a catch 39 on the travel path F of the objects 2, at the exit of the passage 5, are carried out using a step of advancing the chain 37 without end on which are fixed said roller 38 and said cleat 39.
- the endless chain assembly 37 is installed on a frame 50 which is itself integral with the general chassis 51 of the conveyor, which frame 51 is in fact constituted by the sides of said conveyor.
- the toothed wheel 41 is rotated by means of a drive shaft 42 connected to drive means, of a type known per se and not shown in FIG. 6, while the other 40 toothed wheel is provided movable to accommodate several models of chains 37, each chain being adapted to the size of the objects 2 and the length of the batches to be formed.
- the position of the wheel 41 is fixed because it is in relation with the bundling means of the shrinkwrapper which is immediately downstream, as explained previously.
- the wheel 40 is mounted on a shaft 43 which is vertical and able to move in a longitudinal groove 44 formed in the frame 50; its position is lockable by clamping by means of the handle 52.
- the tension of the chain 37 is regulated by means of a cylinder 45 of the gas type, before the shaft 43 is immobilized by the handle 52.
- rails 46, 47 for guiding are provided fixed on the walls 7, 8 able to guide the objects 2 on the strip. 3 conveying both at the entrance and exit of the corridor 5.
- the assembly 4 which carries the flaps 10 and 11, with respect to the assembly 6 endless chain.
- a positioning member 48 fixed on the support assembly 4, making it possible to adjust the distance between the l 4 support assembly and the 6 endless chain assembly.
- the positioning member 48 is an elongated rod whose end, at right angle, serves as a reference point and cooperates with the roller 38 to position the assembly 4 support relative to the assembly 6 endless chain.
- Figure 7 illustrates, in the form of a simple block diagram, the essential elements of the device according to the invention.
- the support assembly 4 which is positioned longitudinally on the belt 3 of said conveyor and the endless chain assembly 6 which is positioned laterally with respect to said belt 3, substantially downstream of said together 4.
- the assembly 4 is displaceable longitudinally relative to the frame 51, guided by means of grooves or slides 53, to adapt the position of the cam 14 of the flap 10 deviator with respect to the position of the rollers 38, which position of the rollers 38 and cleats 39 depends on the type of objects 2 to batch and it also depends on the size of the batch of objects.
- the assembly 4 serves to support the two flaps 10 and 11 which delimit the passage 5 in which the block of objects 2 is blocked.
- the flap 10 is articulated at its upstream portion by means of an axis 12 and the reactive flap 11 is articulated about an axis 13 which is also located at its upstream part, that is to say at the entrance to the passage 5.
- the two axes 12 and 13 are offset longitudinally as indicated above, a distance d which is, for example, between t and 1 / 2J- where I is the length of the objects 2.
- this distance d is close to 1 / 2J
- the downstream end 55 of the flap 10 is slightly offset, in the longitudinal direction, relative to the abutment 17; it is located upstream of this stop 17 to allow anticipation of the movement of said flap 10 during the lateral shift of the head of the line of objects 2 and to avoid jostling the last object of the batch in preparation.
- the distance which separates the downstream end of the flap 10 and the stop 17 is between Vi and 1/4.
- the triggering of the movement of the flap 10 results from the contact between the roller 38 and the cam 14 of said flap; the lifting of said cam 14 is effective when the distance L 'between the stopper 39 and the end 55 of the flap 10 substantially corresponds to the length L of the batch of objects to be formed.
- FIG. 8 shows the line of objects 2 advancing with the band 3 of con traveling at a speed Va, held by the stopper 39 (1) which has just inserted between the object 2a (1) at the head of the line and the last object 2 of the prepared batch.
- the cleat 39 (1) is located at a distance L 'from the downstream end 55 of the flap 10, which distance corresponds to the length L of the object batch to be prepared.
- the roller 38 (2) comes into contact with the cam 14 of the diverter flap and pivots the latter very rapidly.
- This pivoting of the shutter has the effect of deflecting the objects 2 which are in the corridor 5 delimited by said shutter 10 and the shutter 11, on the side of the latter, and of putting the object 2a (2) of the
- the pivoting of the flap 10 has also had the effect of restricting the width of the inlet of the passage 5 and blocking the line upstream of said inlet.
- the blocking and stopping of the line is almost instantaneous at the entrance to the corridor 5 and there is a kind of relaxation of the products that are in said corridor 5 due to the distance between the end 55 of the shutter 10 and the stop 17. This distance has allowed the objects that are in the corridor 5 and which are clamped between the shutters 10 and 11, to decelerate and stop.
- the blocking of the line at the entrance of the passage 5 makes it possible to release the contact pressure between the objects 2 which are in the said passage 5 and, in particular, to prevent the head object 2a (2) from resting with high pressure on the stop 17. Too much pressure between the object 2a (2) and the abutment could introduce an excessive friction between the two with a possible degradation of said object and require a significant effort to return the deflected objects to the object.
- the shutters 10 and 11 are returned to the inactive position by the means 16 springs, as detailed below.
- the pivoting of the flap 10 also allows the passage of the cleat 38 (2) in front of said flap 10 and, as can be seen in the following FIG. 10, it allows it to be put in place behind the previously prepared batch, while waiting to fit between the flap object 2a (2) and the last object 2c (1) of the previous batch.
- the conveyor belt 3 continues to advance at a speed Va and it takes the batch of three objects that are upstream of the stop 17, Figure 10.
- This new batch is supported by the stop 38 (1) whose longitudinal running speed Vt is substantially lower than Va, of the order of 10 to 15%, for example.
- the stopper 39 (1) continues to advance by controlling the movement of the prepared batch and the space E between the objects 2c (1) and 2a (2) becomes sufficient, Figure 11, to allow the insertion without risk of the next stopper 39 (2) in said space.
- This space E has a value of the order of 1 A to MAt.
- the roller 38 (2) leaves the cam 14 and the flap 10 returns to the inactive position in abutment on the abutment 15 'as shown in FIG. 7.
- the return of the flap 10 is carried out automatically under the effect of the pressure exerted through objects 2 which are in the corridor and which are realigned by the flap 11, itself requested by the means 16 springs, Figure 12.
- the newly prepared batch is framed by the cleats 39 (1) and 39 (2) and it is maintained at the speed Vt of travel of said stops which makes it possible to increase the gap between two successive batches by increasing the difference in speed between the conveyor belt 3 and the chain 37 which carries said cleats.
- the cleats accompany the batch prepared over a distance which is of the order of 1.5 times the length L of said batch, for example.
