Definitions
- This invention relates to the field of packaging products in batches, and has as its object a particular packaging device, a machine for processing products comprising such a device, as well as a method for feeding the packaging device.
- the processed products are of the jar, bottle, etc., type and undergo a first phase during which they are finished individually, i.e., essentially filled, capped, and labeled.
- the equipment generally operates on the basis of a rotating carousel, on the periphery of which the labeled products are picked up.
- CA2330454 discloses, for example, a star solution on the periphery of which the products are individually carried.
- a second packaging step is introduced for the purpose of obtaining, at the output, batches of several products, grouped together in a rectangular matrix, with or without staggering, and kept together by a covering of the plastic film type, with or without a bottom part made of a cardboard tray, for example.
- the products therefore appear in a group within which they are held, such as a bundle, for example.
- These batches generally appear in the form of a rectangular base, several products extending along each of the two edges.
- a heating oven is traditionally used to ensure that the film, wrapped around these products that are organized in a matrix, ensures, by shrinking, the holding-together of the various products.
- EP1379457 thus discloses, for example, a wrapping solution, by film, of a batch of products.
- Such secondary packaging equipment is, for example, a bundler, which therefore processes products that, at the input, are distributed transversely to the direction of advance.
- the following steps are generally performed before the wrapping by film, or covering: organization of the flow into separate channels, defining the number of products of a batch that are in the transverse direction; periodic longitudinal separation of the products to define the number of products of a batch in the longitudinal direction, as proposed in, for example, EP2936787; spacing, by means of a feed cycler, of the batches thus created to be synchronized with the wrapping or covering module; and then transfer to the covering conveyor by means of the cycler and a dead plate.
- FR2847242 proposes, for example, to set up, on the one hand, a conveyor for a single-line flow of products, and, on the other hand, inclined relative to the preceding one, a conveyor for a multi-line flow. Under the action of a pusher moving longitudinally on the second conveyor, the inclination between the two conveyors directly transforms, by geometric projection, the single-line flow into transverse rows; then all it takes is to bring them close to one another to obtain a compact multi-line flow.
- U.S. Pat. No. 3,193,078 for its part proposes a movable conveyor portion, one end of which is stationary and receives the products furnished by the single-line flow, and the opposite end of which moves, by pivoting of said portion, to come facing one downstream circulation channel, among many.
- FR2907437 for its part proposes a solution alternatively using a movable intermediate element, receiving the products, after an angled portion, and distributing them in several circulation channels.
- FR2604693 proposes, for example, a solution that optimizes the transition from a single-line flow to a multi-line flow.
- One of the major drawbacks of such a solution is that the crucial subsequent transition from such an overlapping staggered organization to an organization where the products are simply side by side quite often produces jamming and is therefore not reliable particularly at high speed or for products that are not very stiff.
- DE4213557 proposes, for example, a guide that flares out above a conveying means that gradually slows, which naturally ends in this configuration of the staggered products, then to be separated into channels.
- EP1537037 thus proposes a frame that is movable to agitate the loose flow and then to force the transition into separate predefined channels.
- U.S. Pat. No. 5,235,996 for its part finally proposes a solution of longitudinally alternating movable walls, in the extension of the walls that define the channels.
- the invention thus aims to propose a solution in which the feeding of a batch packaging machine is reliable, and also makes possible, as far as practicable, an overall configuration that is versatile and not very bulky.
- the invention proposes using a transfer of products during which each product is referenced and whose position can thus be known and controlled individually. After preparation of the products, the latter are picked up and moved in a controlled way to the input zone of the bundling packaging station, then are deposited there, distributed transversely. Thus avoided is a conveying by conveyor belt on which the products rest and on which their position and stability are in practice not strictly known.
- the invention thus has as its object a packaging device, for batch packaging of products, of the bottle, jar, canister, or the like type, within which, for their packaging, the products move along a conveying direction, said batches having, transversely to said conveying direction, at least two products, said device comprising a feed means, to receive products traveling in a single line in the area of an upstream pick-up zone and to bring them to the area of a deposit zone for their subsequent packaging.
- the feed means comprises, on the one hand, in the pick-up zone, an individual transfer means of the products arriving in a single line, and, on the other hand, at least one collector that is movable and position-controlled, for receiving then moving in a position-controlled way at least one product from the transfer means to the deposit zone, the device further comprising a conveyor in the deposit zone on which the at least one collector deposits the at least one product that it previously picked up in the pick-up zone.
- the invention also has as its object a processing machine using this device, namely a machine for processing products, of the bottle, jar, canister, or other container type, comprising a group for individual preparation of products, delivering finished and individually-referenced products one after the other in a single line.
- This machine is characterized in that it further comprises, mounted downstream from said preparation group and receiving the products that the preparation group dispenses, a packaging device as defined above.
- the invention also has as its object a method used by this device, namely a method for feeding a device for packaging products as described above, within which they move in a conveying direction during their batch packaging.
- This method is characterized in that the products are transferred in an individually-referenced way from an upstream pick-up zone where the products arrive in an individually-referenced way one following the other to a deposit zone in the area of a conveyor where they then travel in several columns for their packaging.
- FIG. 1 diagrams a feeding with a shuttle traveling on a closed-circuit rail between a labeling module and a bundling module;
- FIG. 2 shows a feeding with an alternate circuit to the one in FIG. 1 ;
- FIG. 3 illustrates an embodiment where each collector can pick up simultaneously several products and deposit them at the input of an accumulation of channels
- FIG. 4 shows a piece of equipment to be mounted downstream from a preparation group, comprising a screw for spacing and a transfer wheel;
- FIG. 5 shows a principle with a reverse sense of travel to that of FIG. 4 ;
- FIG. 6 shows the loading of a multi-product collector from a transfer wheel
- FIG. 7 diagrams the traditional architecture of a piece of bundling packaging equipment
- FIG. 8 shows a possibility of travel for the rail on which the collectors travel, with several segments.
- the invention therefore first of all has as its object a packaging device 1 , for batch 2 packaging of products 3 , of the bottle, jar, canister, or the like type, within which, for their packaging, the products 3 move along a conveying direction 4 , said batches 2 having, transversely to said conveying direction 4 , at least two products 3 , said device 1 comprising a feed means 5 , to receive products 3 traveling in a single line in the area of an upstream pick-up zone 6 and to bring them to the area of a deposit zone 7 for their subsequent packaging.
- the products 3 are therefore prepared upstream from the packaging device 1 , particularly in a preparation group of products 3 . These products 3 therefore arrive in the packaging device 1 to be packaged there for shipping.
- the packaging device 1 therefore generally does not modify the structure itself of the products 1 , which is done upstream.
- the product 1 is produced by making the container itself, filling it, capping it, labeling it.
- the sequence of the steps can vary: making the container, labeling, filling, then capping, or making the container, filling, capping, then labeling, etc.
- the packaging device 1 is therefore differentiated from the upstream modules in that it does not intrinsically transform the products 3 individually. Generally, the packaging device 1 therefore receives finished products 3 , ready to be packaged in batches 2 , in the form of a bundle, case, etc. Generally, it receives these products 3 from the last module ensuring the production of the finished product 3 , otherwise called preparation group.
- This preparation group can therefore be the final module itself, namely a labeling module 18 or a filling-capping module.
- the preparation group can also include a series of modules still upstream, such as filling, blow molding, capping, indeed the entire series of modules necessary to produce products 3 from preforms, etc.
- the module just before the packaging device 1 is a labeling module 18 or a filling-capping module.
- the packaging device 1 therefore receives the products 3 from the output of a preparation group, which dispenses finished products 3 individually, and which must be put into groups for shipping.
- the packaging device 1 can preferably be a packaging by bundling, where a film 16 surrounds a batch 2 of products 3 .
- the packaging device 1 then comprises a feed means 5 to recover the products 3 that have just been finished and to process them by bundling during which a film 16 is wrapped around several products 3 to form from them a self-supported group.
- the packaging device 1 must therefore ensure both the movement of the products 3 from the preparation group to the subsequent packaging processing modules and the organization of the products 3 into batches 2 .
- the batches 2 downstream from the feed means 5 , have in particular at least one row of several products 3 that are transverse to said conveying direction 4 , and even several columns of products 3 extending in the conveying direction 4 .
- the batches 2 can be organized in staggered rows, with one product 3 overlapping between two other products 3 beside it, or in a non-staggered matrix.
- the packaging device 1 can be adapted to process several rows of parallel batches 2 in the conveying direction 4 .
- the feed means 5 therefore recovers the finished products 3 in a pick-up zone 6 , in the area of the preparation group, and brings them into a deposit zone 7 , from which they will be packaged in bundles.
- the products 3 are held and positioned individually within the preparation group upstream from the packaging device 1 .
- the feed means 5 comprises, on the one hand, in the pick-up zone 6 , a means 8 for transfer individually of the products 3 arriving in a single line, and, on the other hand, at least one collector 9 that is movable and position-controlled, for receiving and then moving in a position-controlled way at least one product 3 from the transfer means 8 to the deposit zone 7 , the device 1 further comprising a conveyor 10 in the deposit zone 7 on which the at least one collector 9 deposits the at least one product 3 that it previously picked up in the pick-up zone 6 .
- the transfer means 8 which receives the products 3 individually from the preparation group, can take the form of a rotating star between the fingers of which the products 3 can come.
- the at least one collector 9 interacts with this transfer means 8 to pick up the products 3 that it has.
- the products 3 therefore pass from the transfer means 8 to the collector 9 while being continuously referenced, unlike configurations in which, for example, a conveyor belt brings a line of products 3 into a collector 9 , and where the products 3 are therefore not brought to the collector 9 in a position-controlled and referenced way individually.
- the feed means 5 therefore manages the products 3 by systematically controlling the position thereof, so that it is possible, at any time, to know the exact position of each product 3 in the feed means 5 . This tracking of the position is ensured successively at least by the transfer means 8 as well as by the collectors 9 .
- a mechanical interaction is therefore provided between the collector 9 and each product 3 that it carries, so that the position of the collector 9 , which is known, directly gives the information of the position of the products 3 .
- the speed of the products 3 is ensured by the transfer means 8 , which prepares the spacing between the successive products 3 . It is found in the pick-up zone 6 , where the products 3 travel one after the other with a controlled spacing and in a position-controlled way.
- the collector 9 ensures, for its part, at least the movement from the pick-up zone 6 , directly in the area of the transfer means, in which the position of each product 3 is known, to a conveyor 10 in the deposit zone 7 .
- the referencing of the products 3 is therefore never lost in the feed means 5 , in particular since the products 3 of the transfer means 8 are directly picked up by position-controlled collectors 9 .
- a carrying means or star is generally provided at the output of the preparation group, in which the products 3 are held and referenced individually. As will still be presented in detail below, this carrying means of the preparation group and the transfer means 8 of the packaging device can be the same means.
- each product 3 is followed in position from said transfer means 8 , which, as has already been mentioned, can be the carrying means located at the output of the preparation group, or at least synchronized with it.
- the specific processing of each product 3 is thus known and controlled all along the process, without loss of control at the time of the packaging step.
- the packaging device 1 has a downstream accumulation zone 11 , within which the products 3 can be accumulated in several adjacent columns that extend along the conveying direction 4 after having been deposited by the feed means 5 , so as to ensure that each row that is transverse to the conveying direction 4 is complete and has all of the products 3 necessary to form a batch 2 .
- This downstream accumulation zone 11 can be achieved in particular by means of a series of two belts, the first of which travels faster and on which the products 3 are deposited, longitudinal separations delimiting a plurality of channels in which the products 3 are then placed in adjacent columns, for a subsequent separation creating batches 2 of at least one row of several transverse products 3 .
- the collectors 9 therefore bring the products 3 into the extension of the channels delimited by the successive separation walls.
- the accumulation then makes it possible to ensure that the successive products 3 , in the conveying direction 4 , are properly against one another and in sufficient number to form a complete batch 2 , in particular in the case where each batch 2 must have several transverse rows against one another.
- the packaging device 1 comprises, on the one hand, a main conveyor 12 , which moves the products 3 for their packaging within said device downstream from the feed means 5 , and, on the other hand, a deposit conveyor 13 forming the conveyor 10 on which the at least one collector 9 deposits the at least one product 3 that it picked up, the advancing of the deposit conveyor 13 being synchronized with the successive depositing of products 3 on it that is ensured by the at least one collector 9 .
- the main conveyor 12 ensures the movement of the products 3 during their processing by packaging of the bundling type, and can have separate segments, in particular for a circulation within a selection module 22 , a cycler module 14 , a covering means 15 , and even a heat-shrinking tunnel for film 16 .
- a deposit conveyor 13 dedicated to receiving the products 3 deposited by the collectors 9 , and, on the other hand, a main conveyor 12 , downstream from the deposit conveyor 13 that feeds it.
- the operation of the deposit conveyor 13 can thus be synchronized with the depositing of products 3 by the collectors 9 , so that they successively form the transverse rows of the batches 2 , while the main conveyor 12 , in particular if it is the conveyor ensuring the transfer of the products within the shrink tunnel, continues to operate, for example, continuously.
- the deposit conveyor 13 therefore advances by a distance corresponding to one product 3 in the longitudinal direction of the conveying direction 4 to bring forth a free receiving surface for the following row.
- the advance of the deposit conveyor 13 dedicated to the depositing, can thus be calculated so that the rows of the same batch 2 come into contact with one another, but so that the rows of different batches 2 are separated.
- the packaging device 1 preferably takes the form of a piece of bundling packaging equipment, where the successive batches 2 are wrapped with a film 16 .
- a packaging device 1 comprises at least, before the shrink oven, a covering means 15 to wrap the successive batches 2 with film 16 .
- the correct spacing of the batches 2 in the conveying direction 4 can be ensured by the sequence of a selection module 22 and a cycler module 14 , which aim essentially to bring to the input of the covering module 15 compact and complete and correctly-spaced batches 2 .
- the feed means 5 can then deposit the products 3 upstream from these two modules, which will be responsible for delimiting the batches 2 longitudinally.
- the formation of the batches 2 can then be ensured at the time of the depositing of the products 3 by the feed means 5 .
- the packaging device 1 comprises a module designed to separate, longitudinally from one another in the conveying direction 4 , the products 3 organized in adjacent columns extending in said direction, so as to form successive batches 2 , of the cycler module 14 or the selection module 22 type, the feed means 5 depositing the products 3 at the input of said module, optionally in the area of a deposit conveyor 13 .
- the feed means 5 can also deposit the products 3 in batches 2 directly, particularly by depositing them in the same location in the deposit zone 7 , the disengagement of the products 3 previously deposited being ensured by the movement of the deposit conveyor 13 , and even by depositing them at different locations to make up a batch 2 whose products 3 will be moved only once said batch 2 will have been completed. If the batches 2 are organized directly during the depositing by the feed means 5 , it is conceivable that the collectors 9 release the products 3 directly in the area of the covering module 15 , where they will be wrapped with film 16 once the batch 2 is complete.
- the packaging device 1 comprises a covering means 15 , where the products 3 that are organized in successive batches 2 are wrapped with film 16 for a subsequent restraint intended for the formation of self-supported bundles held by said film 16 , the feed means 5 depositing the products 3 at the input of said covering means 15 , optionally directly on the film 16 already partially extended over the belt that then forms the main conveyor 12 .
- This main conveyor 12 can be driven with a continuous movement, the timing of the depositing of the successive products 3 then being coordinated to form the batches 2 directly on it.
- the packaging device 1 can also have other characteristics that are presented in detail below.
- the at least one collector 9 is set in motion between the pick-up zone 6 and the deposit zone 7 as a result of a linear motor principle.
- the collector 9 is therefore carried on a shuttle whose movement is caused by a linear motor principle.
- Such a shuttle therefore rests on a base with which a magnetic interaction is produced that moves the shuttle in one direction or the other along the base or rail 21 .
- the speed of the collector 9 is therefore variable and its position is known specifically, which contributes to controlling the position of the products 3 : the position of each collector 9 is known, and, since the collector 9 controls the position of the at least one product 3 that it carries, and even that it holds firmly, the position of each product 3 is therefore known at least relative to the frame of the conveyor 10 .
- the packaging device 1 is therefore equipped with a control unit that guides the movement of the collectors 9 through the linear motor on which they are mounted. As is also mentioned elsewhere, this guiding unit preferably also controls the movement of the conveyor 10 on which the products 3 are deposited, and this in a coordinated way with the movement of the collectors 9 .
- the packaging device 1 further comprises a guide rail 21 with a closed loop portion, the at least one collector 9 taking the form of a shuttle traveling on said rail 21 , between the pick-up zone 6 and the deposit zone 7 .
- the rail 21 therefore ensures the linear motor function and extends preferably essentially horizontally, i.e., parallel to the plane of the conveyor 10 .
- the shuttles carrying the collectors 9 therefore travel along this rail 21 , which makes it possible for them to arrive both in the pick-up zone 6 and in the deposit zone 7 .
- the closed portion of this rail 21 makes it possible to perform both the coming and the going.
- the collectors 9 can be moved in relation to one another and can be moved separately. The position of each collector 9 is controlled individually.
- the circuit of the rail 21 comprises an active portion that serves to connect, in one direction and in the other, the pick-up zone 6 and the deposit zone 7 , as well as at least one switch making it possible to connect said active portion to other portions of the circuit, as FIG. 8 shows.
- the active portion therefore makes it possible for the collector 9 to travel to fulfill its conveying function between the pick-up zone 6 and the deposit zone 7 .
- the other portions can be used, for example, to switch off products 3 by bringing the collectors 9 , which are identified as carrying them, onto a particular segment. These other portions can also be used to swap collectors 9 , and therefore to remove used collectors 9 for maintenance, and even to switch off collectors 9 that become unsuitable due to a change of format, or else to temporarily leave collectors 9 waiting for a new format of products 3 , etc.
- the rail 21 can thus be provided itself with a zone for accumulating empty or full collectors 9 , to ensure an accumulation between the preparation group and the conveyor 10 .
- the circuit of the guide rail 21 further comprises at least one portion dedicated to receiving waiting collectors 9 , particularly collectors 9 coming from the pick-up zone 6 but not yet being authorized to go into the deposit zone 7 , or collectors 9 coming from the deposit zone 7 but not yet being authorized to go into the pick-up zone 6 , or else collectors 9 designed for another product 3 format.
- the circuit of the guide rail 21 further comprises, connected to the active portion, an ejection portion on which the collectors 9 are brought to circulate that are conveying at least one non-compliant product 3 collected in the pick-up zone 6 , to prevent said product 3 from being brought into the deposit zone 7 .
- an ejection portion on which the collectors 9 are brought to circulate that are conveying at least one non-compliant product 3 collected in the pick-up zone 6 , to prevent said product 3 from being brought into the deposit zone 7 .
- the at least one collector 9 has a capacity that corresponds to a single product 3 , so that a collector 9 can take away only a single product 3 at a time from the pick-up zone 6 to the deposit zone 7 , the feed means 5 comprising particularly a plurality of collectors 9 , preferably at least one group of collectors 9 formed by as many collectors 9 as the number of products 3 that form one row of a batch 2 that is transverse to the conveying direction 4 , and even as the number of products 3 that form several aligned rows, intended to contribute to several batches 2 that are aligned transversely.
- collectors 9 that process the products 3 individually are that the possible ejection off the useful portion of the rail 21 can be done precisely, while avoiding taking off products 3 that are compliant, but mounted on a collector 9 that must be taken off because it comprises at least one non-compliant product 3 .
- Another advantage is that in case of a shortfall on the transfer means 8 , the preceding collector 9 can be moved, and the following collector 9 remains in waiting mode. It will thus be understood that generally, the control of the products 3 individually ensures an improved, more efficient, treatment process, since each product 3 undergoes only the operations that relate to it. In other words, the processing of each product 3 is suited specifically to it.
- the at least one collector 9 has a capacity of several products 3 , so as to be able to pick up in the pick-up zone 6 and bring to the deposit zone 7 a plurality of products 3 each time, preferably as many products 3 as the number of products 3 that form a row of the batch 2 that is transverse to the conveying direction 4 , and even several aligned rows intended for several batches 2 beside one another.
- the multiple products 3 that the collector 9 can take therefore arrive one after the other in the collector 9 , and, as FIG. 6 shows, the collector 9 is moved gradually to put an open receiving receptacle opposite each new product 3 to be recovered from the transfer means 8 .
- the advantage of a multiple collector is in particular to be able easily to deposit all of the products 3 simultaneously in the deposit zone 7 .
- the feed means 5 comprises a plurality of collectors 9 that are movable in relation to one another, particularly to come near or move away on the guide rail 21 . It is thus possible, for example, to group the collectors 9 beside one another to handle their depositing simultaneously.
- collectors 9 generally deposit the products 3 at the same location in the longitudinal direction, it is preferable that all of the products 3 that form the same transverse row be effectively deposited at the same time, which simplifies the adjustment of the longitudinal movement of the conveyor 10 .
- these collectors 9 can, to deposit the products 3 , be grouped against one another and then deposit the products 3 simultaneously.
- the feed means 5 comprises, to furnish the products 3 individually to the at least one collector 9 , in the area of the pick-up zone 6 , a means 8 for transfer of products 3 individually, of the star type, the speed of the product 3 in said transfer means 8 and the speed of the collector 9 being parallel, during the transition from one to the other, which is in particular illustrated in FIG. 6 , and optionally also in the same direction and range.
- the product 3 therefore does not undergo any variation in either movement or speed during its introduction into the collector 9 .
- the products 3 therefore go from a means of movement in which they are referenced individually, namely the transfer means 8 , to another means of movement in which they are once again referenced individually, namely a collector 9 . This transition from one to the other is done without impact or pressure for the product 3 , which is therefore not destabilized and does not risk falling or being broken.
- the device is thus differentiated from the equipment where the products 3 arrive in a collector with a speed that is perpendicular to the subsequent movement of the collector 9 , and where the products 3 then undergo impacts that can lead to falls.
- FIG. 6 shows, at the time the product 3 goes from the transfer means 8 to the collector 9 , it is driven by a movement of the same speed as the speed that the collector 9 has for heading toward the deposit zone 7 .
- the collector 9 in particular when it is proportioned for several products 3 , can therefore have a continuous movement without a risk of jamming.
- the invention also has as its object a machine 17 for processing products 3 , of the bottle, jar, canister, or other container type, comprising a group for preparation of individual products 3 , delivering finished and individually-referenced products 3 one behind the other in a single line.
- the preparation group for products 3 consists in at least the final step of production of the products 3 themselves, and even at least one other upstream step of it.
- the group for preparation of products 3 thus comprises in particular, for example, a plastic bottle blow-molding module, a filling module in which the products 3 are filled, a capping module where the products 3 are capped, and/or a labeling module 18 within which a label is affixed on each successive product 3 individually, particularly by gluing or printing.
- the preparation group can thus consist essentially in a final labeling module 18 , or else any finalizing module of product 3 or any combination of such modules.
- this machine further comprises, mounted downstream from said preparation group and receiving the products 3 that the preparation group dispenses, a packaging device 1 as described above.
- the products 3 are therefore individually position-referenced and are fundamentally finished and ready for packaging into batches 2 by the packaging device 1 whose feed means 5 preserves the individual referencing of the products 3 .
- the preparation group and the packaging device 1 are arranged so that, seen from above, the feed means 5 , between the preparation group and the following elements of the packaging device 1 , extend approximately perpendicular to the conveying direction 4 of the conveyor 10 in the deposit zone 7 , or of the main conveyor 12 . More particularly, the preparation group is therefore as housed between, on the one hand, the feed means 5 and, in perpendicular, the equipment following the packaging device 1 . This ends then in a configuration where the collectors 9 are easy to access in case of a need for maintenance, and where an extremely compact configuration can be obtained to contain both the packaging device 1 and the upstream preparation group.
- the collectors 9 between, on the one hand, the preparation group, and, on the other hand, the following modules of the packaging device 1 , such as the selection module 22 or cycler module 14 or the covering means 15 , are therefore driven by a movement that is essentially perpendicular to the conveying direction 4 of the main conveyor 12 .
- the overall arrangement therefore forms a compact machine, and the various functional groups therefore remain accessible.
- the packaging device 1 thus forms, seen from above, an L configuration, in the hollow of which is found the preparation group.
- the processing machine comprises an ejection means to remove, before the pick-up by the feed means 5 , the non-compliant products 3 at the output of the preparation group.
- This ejection is therefore positioned preferably in the area of the carrying means at the output of the preparation group, since the products 3 are referenced there and known by position individually.
- the products 3 detected upstream as non-compliant are thus ejected and it is avoided that non-compliant products 3 are picked up by the collectors 9 , which ensures that the products 3 provided by the feed means 5 are all compliant.
- the transfer means 8 of the packaging device 1 forms the output of the preparation group and thus itself ensures the transfer of products 3 between, on the one hand, the preparation group, and, on the other hand, the packaging device 1 , more particularly directly in the area of the collectors 9 of the feed means 5 .
- the transfer means 8 thus forms both the output of the preparation group and the input of the feed means 5 of the packaging device 1 .
- the processing machine 17 thus ensures itself and, in an integrated way, on the one hand, the function of the preparation group, namely the labeling or final filling-capping, and also even upstream preparation functions, and, on the other hand, the function of packaging of the products 3 that are dispensed.
- the processing machine 7 is therefore provided with one and the same means processing the products 3 in an individually-referenced way at the interface between the packaging device 1 and the preparation group.
- the finished products 3 at the output of the preparation group therefore travel on a transfer means 8 in the area where the collectors 9 of the feed means 5 come to pick them up directly.
- the continuity of the referencing is thus ensured.
- the feed means 5 of the packaging device 1 takes the products 3 directly at the referenced output of the products 3 of the preparation group.
- the processing machine 17 has, on the one hand, a wheel 19 , for referenced transfer, positioned at the output of the preparation group and delivering the products 3 individually, and, on the other hand, a screw 20 between said wheel 19 and the transfer means 8 of the feed means 5 , said screw 20 and the transfer means 8 being synchronized.
- the referenced transfer wheel 19 can take the shape of a star at the output of the labeling module 18 that forms the preparation group.
- the screw 20 is therefore synchronized with the movement of the transfer means 8 downstream, which brings the products to the collectors 9 of the feed means 5 . It makes it possible either to move the products 3 in a referenced way from the output of the upstream preparation group to the transfer means 8 , or to recreate a referencing.
- the screw 20 is also synchronized with the transfer wheel 19 of the output of the preparation group, so as to guarantee a position-controlled movement of the products 3 from the output of the labeling module 18 or preparation group, to the pick-up by the at least one collector 9 .
- the position control of each product is therefore optimal, and the process is efficient, suited to each product 3 .
- the processing machine 17 has an upstream accumulation zone 23 for the products 3 downstream from the wheel 19 and upstream from the screw 20 , where the products 3 are freely accumulated in a single line to form a continuous flow even if the flow of entering products 3 is interrupted, for example considering an ejection, upstream, of non-compliant products 3 .
- the invention also has as its object a method using the invention as described above, namely a method for feeding a device 1 for packaging products as described above, within which they move in a conveying direction 4 during their packaging in batches 2 , particularly by bundling.
- the products 3 are transferred in an individually-referenced way from a pick-up zone 6 upstream where the products 3 arrive in an individually-referenced way one following the other to a deposit zone 7 in the area of a conveyor 10 where they then travel in several columns for their packaging.
- the products 3 are therefore deposited in successive longitudinal columns directly by the feed means 5 .
- Their correct positioning for bundled packaging by lots 2 is therefore controlled and guaranteed, unlike feeding solutions based on conveyors of the moving-belt type.
- the collectors 9 therefore release at the same time all of the products 3 that form a transverse row in the batch 2 , which makes it possible to simplify the synchronization of the movement of the conveyor 10 or dedicated deposit conveyor 13 .
- the depositing by the collectors 9 can thus form the successive transverse rows of a single batch 2 or of several batches 2 at the same time, in the cases where the packaging device 1 processes several columns of batches 2 that are beside one another.
- the products 3 in the collectors 9 therefore reproduce the shape of the transverse row.
- collectors 9 can be brought near to one another to reproduce, together, the configuration of the row of the batch 2 .
- the movement of advance of the conveyor 10 on which the products 3 are deposited and the frequency of depositing the products 3 on it are coordinated, so that the conveyor 10 advances by the equivalent of one transverse row as soon as such a row has been deposited, to make room for the next row in the batch 2 or else as soon as the collectors 9 , intended to transfer together an entire row of a future batch 2 , have deposited the products 3 that it contained.
- the method can also have other technical characteristics that are presented in detail below.
- the method comprises an ejection step, after the pick-up of the product 3 , during which a collector 9 comprising at least one non-compliant product 3 is discharged from the circuit connecting it to the deposit zone 7 .
- the ejection of non-compliant products 3 is therefore done in the area of the collectors 9 , as a result of the design of the circuit on which they travel and as a result of their individual guiding. Since the position of each product 3 is known, it is possible to avoid supplying defective products 3 into the batches 2 .
- the collectors 9 are grouped to form together a group of products 3 that are aligned and that are to be simultaneously deposited, particularly a row of a batch 2 , which makes it possible in particular to use one deposit step for the group of products 3 , and this in a simultaneous way.
- the packaging device 1 takes the form of a bundling device, in which, for the bundling operation itself, the products 3 travel on a main conveyor 12 in the form of batches 2 , in a conveying direction 4 .
- a batch 2 has several products 3 aligned in a row that is transverse to the conveying direction 4 , and generally also several products 3 aligned in the conveying direction 4 .
- a batch 2 therefore has a matrix configuration, with or without staggering, the products 3 then being aligned compactly both in the conveying direction 4 and transversely.
- FIG. 7 shows, the batches 2 thus move in the packaging device 1 while being spaced from one another in the conveying direction 4 .
- a batch 2 of products 3 generally is wrapped with a plastic film 16 , then travels into a heated tunnel where the film 16 shrinks and then holds the products 3 against one another.
- the products 3 are generally bottles, jars, etc., filled and labeled in a preparation group, before this secondary packaging step that, for its part, aims to group them and bind them in self-supported bundles. Upstream from this packaging device 1 , therefore, there is equipment that produces the product 3 itself, generally ending with a labeling step.
- a labeling module 18 generates at its output individual products 3 , one after the other, generally by means of a rotating carousel, the packaging device 1 producing, for its part, successive batches 2 each comprising several products 3 . At the output of the labeling module 18 , the products 3 therefore travel one following the other in the direction of advance.
- a labeling module 18 using rotating elements, of the carousel type, on the periphery of which the products 3 are located, is, for example, described in US2010276028.
- the labeling module 18 comprises at least, at its output, one means for carrying the individual products 3 , such as a rotating star between the fingers of which the products 3 are found.
- the products 3 are therefore moved in a controlled manner individually by this carrying means, unlike, for example, a loose carrying solution where the position of each product 3 is not known precisely, or even a conveying by column on a belt, then not controlled because it does not prevent the sliding of the products 3 and even their falling, being unresponsive to their absence, etc.
- the packaging device 1 is thus equipped with a feed means 5 , which ensures its supplying of products 3 from the output of the labeling module 18 .
- the organization of the products 3 must go from an organization of a single column at the output of the labeling module 18 or preparation group to an organization of several columns for packaging in the packaging device 1 in the form of batches 2 based on rows of several products 3 each.
- Several batches 2 can further be found aligned transversely to the conveying direction 4 . Going from the single-line configuration to the multi-line configuration is achieved by means of the feed means 5 , as it is described here.
- the feed means 5 thus comprise at least one movable collector 9 , this collector 9 being able to pick up and move at least one product 3 from the pick-up zone 6 , where the products 3 still travel in a single line, to the deposit zone 7 where the products 3 are organized in several columns on a conveyor 10 that takes them to be packaged.
- FIG. 1 shows, for example, a feeding device 5 that comprises only one collector 9 , this collector 9 being able in turn to receive a single product 3 and to place it in the corresponding column.
- the collector 9 of the feed means 5 is movable in a controlled and known way, which makes it possible to know at each moment with precision the position of the at least one product 3 that it moves.
- the collector 9 thus comprises, for example, for each product 3 that it must move, a receptacle to simply at least hold the product 3 by the body, or else a gripper to grab strictly speaking each product 3 , at its neck or elsewhere.
- the position of the collector 9 when it lets go of the products 3 in the deposit zone 7 , is therefore known and controlled, at least in the direction that is transverse to the conveying direction 4 .
- This thus makes it possible to guarantee the transverse position of the at least one product 3 brought by the at least one collector 9 and therefore to deposit said at least one product 3 immediately at the proper location in the transverse direction.
- the makeup of the batches necessitates products 3 distributed transversely to the conveying direction 4 , which such a collector 9 can achieve by a known and controlled position, designed to ensure a referencing of the at least one product 3 that it moves.
- the collectors 9 are actually preferably equipped with mechanical means to pick up each product 3 separately, and are mounted on a movable shuttle in a controlled way.
- the product 3 is therefore referenced between the pick-up zone 6 , which can be directly the output of the preparation group, and the deposit zone 7 , from which the secondary packaging operation itself is performed. It is thus possible to control exactly the location where the product 3 will be deposited on the conveyor 10 , i.e., in particular in the area of whatever longitudinal column.
- the control and of the referencing of the product 3 during the travel and during the depositing in the deposit zone 7 it is possible to deposit a product 3 intended to form the first product 3 of a transverse row of a batch 2 , then, with another collector 9 , to deposit the product 3 intended to form the second product 3 of such a row, then that for the third product 3 of the row, etc.
- a collector 9 can actually collect several products 3 successively while receiving them beside one another in a direction that is then transverse to the conveying direction 4 , so that the simultaneous depositing of all of the products 3 immediately leads to the making of a transverse row of several products 3 , to create, by grouping several of them, at least one batch 2 , and even several batches 2 aligned transversely to the conveying direction 4 .
- the referencing of the individual products 3 by means of the movable collector 9 in a controlled way thus immediately ensures the controlled depositing in successive longitudinal columns.
- the products 3 are released by the collectors 9 in the area of a deposit zone 7 in which a conveyor 10 is found. They are deposited on the conveyor 10 that then introduces them into the core of the sequence of the packaging steps: traveling in separate channels; separation of the groups of transverse rows that define a batch 2 ; synchronization with the covering or wrapping; or covering directly. The products 3 are thus deposited at the latest during the covering itself, or wrapping by the film 16 , directly at the input of one of these steps.
- the release of the products 3 can therefore, depending on the configurations, be done at different locations before the wrapping of the batch 2 with the film 16 in the covering means 15 : either at the input of a conveying in channels; or at the input of a referencing cycler; or directly at the input of the covering table 15 .
- a longitudinal accumulation can be provided downstream from the depositing by the collector 9 , and even directly in the area of the deposit zone 7 . Traveling channels are then preferably accommodated preferably by means of longitudinal walls to prevent the overlapping of the products 3 in the form of a staggered organization that would cause the advantage of the transverse position-controlled depositing to be lost. The products 3 are then accumulated in these channels of longitudinal columns, which guarantees the presence of a sufficient number of products 3 in the conveying direction 4 to make up batches 2 formed by several transverse rows.
- Such a downstream accumulation zone 11 downstream from the transfer, by the fleet of collectors 9 that comprises the feed means 5 , makes it possible in particular to avoid gaps in the continuous matrix arrangement of the products 3 as is required for the packaging of bundled batches 2 . It also makes it possible to use configurations where the number of products 3 that each collector 9 conveys does not correspond to the number of products 3 of a transverse row of a batch 2 . Actually, in cases of this kind, the products 3 of the same row are not necessarily released at the same time, and it is then useful to provide such a downstream accumulation zone 11 to complete each transverse row.
- each collector 9 is able to receive several products 3 and to move them simultaneously toward the deposit zone 7 .
- the products 3 are therefore received successively in such a collector 9 from the output of the labeling module 18 , preferably directly in the area of the carrying means at its star-type output.
- the collector 9 thus has single reception zones that are aligned in a direction that corresponds subsequently to the direction that is transverse to the conveying direction 4 , or the direction of a row.
- the products 3 of the collector 9 are then all deposited simultaneously on the conveyor 10 in the deposit zone 7 .
- This assembly of products 3 thus directly forms a row of the batch 2 that is transverse to the conveying direction 4 , and the break-up step and then organization of a flow of products 3 that is initially single-line are avoided.
- the conveyor 10 advances by a distance that corresponds to such a row, so that the next row comes against the preceding one, which immediately, and by the sole collection-then-transfer operation, results in the formation of a compact batch 2 .
- the spacing between the batches 2 can be managed by lengthening the period of time that separates two successive deposits of products 3 intended to form a row and/or by speeding up the movement of the conveyor 10 .
- the ejection of non-compliant products 3 can be organized in the area of the output of the labeling module 18 , before the pick-up of the products 3 by the collectors 9 , in the area of the star carrying means.
- a control means is incorporated within the labeling module 18 and makes it possible to identify the products 3 that are not acceptable. Since the travel of each product 3 within the labeling module 18 is followed, it is possible to eject the non-compliant products 3 precisely, in particular in the area of the individual carrying means placed at the output of the labeling module 18 that forms the preparation group.
- a specific conveyor can be provided in the area of the star wheel at the output of the labeling module 18 so that the non-compliant products 3 are deposited there, so that only the compliant products 3 can continue their travel to the collectors 9 .
- the flow of products 3 downstream from this star can therefore have interruptions or missing products 3 , which correspond to products 3 that have been eliminated upstream, and the operation of the collectors 9 is adjusted.
- the ejection, downstream from the labeling module 18 , of the non-compliant products 3 can also be ensured by the collectors 9 themselves, once the products 3 are picked up.
- the collectors 9 are collectors 9 provided for a single product 3 at a time, the collector 9 identified as moving a non-compliant product 3 can thus quite simply not be brought into the deposit zone 7 .
- a complementary device can remove from the collector the defective product 3 , etc.
- a single-line free accumulation zone can be provided, for example, for the products 3 upstream from the feed means 5 , which guarantees that the latter picks up, one after the other, continuously, products 3 that are all compliant.
- a multi-line accumulation zone can also be provided downstream from the multi-line release of the products 3 by the feed means 5 .
- the plurality of transverse rows that are successive and in contact that the batches 2 comprise is thus defined subsequently in this accumulation, for example by a selection module 22 or else a cycler module 14 , see FIG. 7 .
- This downstream accumulation makes it possible for the products 3 that are deposited in a column after a missing product 3 to catch up with those already deposited previously.
- the feed means 5 preferably recovers the products 3 in the area of a referenced transfer means 8 or carrying means, generally in the form of a wheel 19 or star with peripheral receptacles in which each time a product 3 can be located at the output of the labeling module 18 .
- the labeling can, moreover, be performed while the products 3 are in this transfer means 8 .
- the collectors 9 for their part, travel on a guide or rail 21 that encounters the peripheral path of the transfer means 8 to be able to perform a carrying change in the area of the products 3 that then go from a carrying by the transfer means 8 or wheel to a carrying by the collectors 9 , as illustrated in FIG. 6 .
- the collector 9 is preferably driven by a movement similar to that of the product 3 in the wheel 19 , thus guaranteeing a fluid passage from one to the other.
- the receptacle in which the product 3 is located in the area of the wheel or star and the receptacle of the collector 9 in which it must continue its path are therefore at least momentarily driven by a movement of the same speed, direction, orientation, and rapidity. It will be noted that a way of handling the possible absence of product 3 in the wheel after the elimination of a defective product can then consist in not advancing the collector 9 if the receptacle opposite is empty of product 3 , which guarantees that the collectors 9 arriving in the deposit zone 7 are systematically filled with compliant products 3 .
- FIGS. 5 and 6 show, in the case where the collector 9 is scaled for several products 3 , once positioned for reception, it extends linearly along a tangent to the output star of the labeling module 18 , so that its movement successively brings the single reception zones to the periphery of the star.
- the guide rail 21 can, for example, have a curvature such as a half-turn, opposite the curvature of the transfer means 8 , and in the area in which the transition of the products 3 from the transfer means 8 to the collectors 9 is managed.
- the transfer into the collector 9 can also be done while it travels on a straight portion.
- the collectors 9 are therefore used in a cyclic way: after having recovered the at least one product 3 , the collector 9 is then going to deposit it, then, by a return portion, come back to begin this cycle again.
- the rail 21 therefore has a useful closed-loop portion on which the collectors 9 travel to move the products 3 between the two zones.
- the integration between, on the one hand, the labeling module 18 and, on the other hand, downstream, the packaging device 1 , and, more particularly, its feed means 5 can be arranged in different ways.
- the feed means 5 picks up the products 3 directly from the star or wheel 19 at the output of the labeling module 18 or preparation group, which results in a piece of equipment incorporating both the function of the at least final making of the product 3 , of the labeling type, and the function of packaging by bundling of batches 2 .
- the feed means 5 of the packaging device 1 can also load the products 3 from a star that is different from that of the output of the labeling module 18 , which makes it possible in particular to reuse an existing labeling module 18 , without structural modification, and therefore to propose so-called “retro-fit” solutions.
- the feeding of this star 8 with products 3 is preferably done by means of a screw 20 whose pitch normally corresponds to the spacing of the receiving receptacles on the star.
- the pitch can, of course, be scalable between the beginning and the end of the screw 20 .
- Such a screw 20 makes it possible generally to reference products 3 that previously traveled possibly freely.
- Such a free conveying can come from the preparation group directly or after division of the single-line flow that it dispenses in several parallel flows.
- the screw 20 can here be used while being totally synchronized both with the downstream star or transfer means 8 and with the upstream carrying means, at the output of the labeling module 18 .
- this screw 20 therefore performs a referencing, spacing, and movement function, during which the position of each product 3 is known and controlled from the output of the labeling module 18 to a transfer means 8 that is then offset.
- An upstream accumulation zone 23 can also be provided, in which the products 3 coming out of the labeling module 18 one after the other are conveyed freely, for example with a downstream conveyor belt that travels faster than the speed of the screw 20 .
- the screw 20 is then arranged downstream from this upstream accumulation zone 23 and again references the products 3 for their pick-up in the transfer means 8 that requires that the products 3 be spaced from one another in a controlled way. Downstream from the star of the labeling module 18 , the products 3 , until then referenced individually, therefore go into an upstream accumulation zone 23 in which they are grouped together in contact with one another.
- the feed means 5 is provided preferably with a screw 20 , which defines a space between the products 3 and with a wheel that then ensures the transfer of the products 3 .
- the configurations where the screw 20 is not synchronized make possible a mounting downstream from a labeling module 18 or existing preparation group, without structural modification.
- the use of a screw 20 that is synchronized on the output of the labeling module 18 necessitates a slight structural adaptation of the existing labeling module 18 .
- the configurations where the products 3 are directly picked up by the collectors 9 at the output of the labeling module 18 form complete, totally integrated machines that ensure both the bundling function and at least one labeling function. In the cases where the wheel of the preparation group and the wheel of the feed means 5 are not the same, the latter makes it possible to correctly reference and control each product 3 before they are picked up individually, by the collectors 9 .
- the feed means 5 therefore preferably ensures, on the one hand, the movement of the products 3 from the pick-up zone 6 at the output of the labeling module 18 to the deposit zone 7 , which can be situated at different locations upstream from a covering means 15 by film 16 , and, on the other hand, the creation, from a continuous single-line flow of products 3 one behind the other, of segments intended to form the rows of the batches 2 that are transverse to the conveying direction 4 , thus forming a multi-line flow.
- the coordination with the advance of the conveyor 10 that successively moves these rows of products 3 in the conveying direction 4 makes it possible to obtain batches 2 , each comprising several such rows pressed against one another.
- a traditional bundling packaging device 1 has the series of various modules until the one in which the matrix batch 2 of products 3 is wrapped with a film 16 , see FIG. 7 .
- the feed device 5 can therefore furnish the products 3 at different locations upstream from this wrapping function:
- the products 3 can be deposited by the feed means 5 on a dedicated deposit conveyor 13 , then feeding one of these inputs.
- the feed means 5 preferably comprises a battery of collectors 9 , which travel on a guide rail 21 that comprises said means. It is thus possible to drive these collectors 9 with movement as a result of a magnetic linear motor principle, which has the advantage of being able both to manage and control the position and speed of each collector 9 separately.
- the collectors 9 are therefore mounted on shuttles that are moved as a result of the linear motor principle.
- the collectors 9 are thus movable in relation to one another. Consequently, before the depositing, it is possible to bring them close to one another until they form a compact alignment, extending transversely to the conveying direction 4 in the deposit zone 7 then to reproduce the row of the batch 2 that is transverse to the conveying direction 4 . They can then simultaneously deposit the products 3 that they contain, and then form a row. This is in particular useful with collectors 9 that convey only one product 3 at a time and that are not grouped together when they collect the products 3 .
- each collector 9 Since the exact position of each collector 9 is known and controlled, it is also possible to provide that they release the at least conveyed product 3 , each in turn, in the corresponding longitudinal column, then to advance the deposit conveyor 13 for the next row only once a complete row has been deposited.
- the rail 21 is preferably in a closed loop, between two turnarounds that are located approximately, for the one, in the area of the output of the labeling module 18 and, for the other, in the area of the modules that are used for the batch 2 packaging.
- the circuit that the rail 21 forms therefore has a main portion that is used for the circulation of the collectors between the pick-up zone 6 and the deposit zone 7 for moving the products 3 between these zones.
- This circuit can also have branches or switches to other segments that are used, for example, to switch off collectors 9 that are defective or that convey at least one non-compliant product 3 .
- These other segments can also be used for an accumulation of products 3 , an accumulation of loaded or empty collectors 9 , optionally collectors 9 that are compatible with another format, etc.
- the complete circuit of the rail 21 can therefore be formed by, for example, a main closed loop, then of portions optionally superposed with one another, that the products 3 can leave and then rejoin, etc., as FIG. 8 shows.
- the successive loops are preferably counter-rotating.
- the feed means 5 is therefore substituted for the traditional solutions of conveying by belt on which the products 3 rest and where the transition from a single-line flow at the labeling output to a multi-line flow for packaging creates jamming or crushing problems.
- collectors 9 with a capacity that is less than a transverse row of the batch 2 are grouped together, continuously or temporarily during the cycle, to convey together as many products 3 as at least one row must contain of them, and to deposit them simultaneously.
- collectors 9 that work with a single product 3 each time guarantees the versatility of the feed means 5 , since a new batch 2 format, in terms of the number of products 3 in a transverse row or in a longitudinal column, requires no structural modification, only a different adjustment of the operation of the collectors 9 .
- an additional advantage of using collectors 9 having a single capacity is their removal from the circuit as soon as the particular product 3 that they convey is not compliant.
- a collector 9 In the cases where the capacity of the collectors 9 corresponds to the number of products 3 in a transverse row, a collector 9 normally conveys each time the number of products 3 for a row. It is then possible to release simultaneously all of the products 3 that it carries, then creating a row in a single operation. The longitudinal movement of the conveyor on which the products 3 are deposited then makes it possible to accumulate rows against one another in the conveying direction 4 .
- the feed means 5 ensures the individual distribution of the products 3 in the direction that is transverse to the conveying direction 4 .
- each product 3 is picked up directly from the labeling module 18 , the orientation of the product 3 is controlled, which has a certain advantage from the moment that the products 3 have a special shape and/or that their orientation in the batch 2 is important, such as, for example, products 3 with a rectangular base, etc., or else circular products 3 , but that are to be positioned in a pre-defined way.
- the orientation of the product 3 is controlled, which has a certain advantage from the moment that the products 3 have a special shape and/or that their orientation in the batch 2 is important, such as, for example, products 3 with a rectangular base, etc., or else circular products 3 , but that are to be positioned in a pre-defined way.
- As each product 3 is picked up and preferably restrained in the collector 9 , its orientation is controlled. It is also possible to use a collector 9 with a degree of freedom around a shaft, driven or not, to modify the orientation of the products 3 in a controlled way between the pick-up by the collectors 9 and their deposit.
- An accumulation means can also be provided between the pick-up zone 6 and the deposit zone 7 , for example with an accumulation table on which the collectors 9 deposit then pick up again the products 3 , or another means making it possible to ensure a buffer between the labeling module 18 and the packaging device 1 .

Abstract
Description
- This invention relates to the field of packaging products in batches, and has as its object a particular packaging device, a machine for processing products comprising such a device, as well as a method for feeding the packaging device.
- In this field, the processed products are of the jar, bottle, etc., type and undergo a first phase during which they are finished individually, i.e., essentially filled, capped, and labeled. At the output of such a phase, the equipment generally operates on the basis of a rotating carousel, on the periphery of which the labeled products are picked up. CA2330454 discloses, for example, a star solution on the periphery of which the products are individually carried.
- After this first preparation step of a product that is then ready to use, a second packaging step is introduced for the purpose of obtaining, at the output, batches of several products, grouped together in a rectangular matrix, with or without staggering, and kept together by a covering of the plastic film type, with or without a bottom part made of a cardboard tray, for example. At the output of this second packaging step, the products therefore appear in a group within which they are held, such as a bundle, for example. These batches generally appear in the form of a rectangular base, several products extending along each of the two edges. A heating oven is traditionally used to ensure that the film, wrapped around these products that are organized in a matrix, ensures, by shrinking, the holding-together of the various products. EP1379457 thus discloses, for example, a wrapping solution, by film, of a batch of products. Such secondary packaging equipment is, for example, a bundler, which therefore processes products that, at the input, are distributed transversely to the direction of advance.
- For this second packaging step, it is therefore necessary to transform a flow from a single-line configuration upstream, at the output of the preparation group, to a multi-line configuration, i.e., with several longitudinal columns, each intended to form a longitudinal portion of a batch.
- In bundling packaging equipment, the following steps are generally performed before the wrapping by film, or covering: organization of the flow into separate channels, defining the number of products of a batch that are in the transverse direction; periodic longitudinal separation of the products to define the number of products of a batch in the longitudinal direction, as proposed in, for example, EP2936787; spacing, by means of a feed cycler, of the batches thus created to be synchronized with the wrapping or covering module; and then transfer to the covering conveyor by means of the cycler and a dead plate.
- For transforming the flow into several channels, FR2847242 proposes, for example, to set up, on the one hand, a conveyor for a single-line flow of products, and, on the other hand, inclined relative to the preceding one, a conveyor for a multi-line flow. Under the action of a pusher moving longitudinally on the second conveyor, the inclination between the two conveyors directly transforms, by geometric projection, the single-line flow into transverse rows; then all it takes is to bring them close to one another to obtain a compact multi-line flow.
- U.S. Pat. No. 3,193,078 for its part proposes a movable conveyor portion, one end of which is stationary and receives the products furnished by the single-line flow, and the opposite end of which moves, by pivoting of said portion, to come facing one downstream circulation channel, among many.
- FR2907437 for its part proposes a solution alternatively using a movable intermediate element, receiving the products, after an angled portion, and distributing them in several circulation channels.
- A traditional way of transforming a single-line flow into a multi-line flow is based optionally also on an intermediate step of loose conveying, where the products are organized then generally by staggering. FR2604693 proposes, for example, a solution that optimizes the transition from a single-line flow to a multi-line flow. One of the major drawbacks of such a solution is that the crucial subsequent transition from such an overlapping staggered organization to an organization where the products are simply side by side quite often produces jamming and is therefore not reliable particularly at high speed or for products that are not very stiff.
- DE4213557 proposes, for example, a guide that flares out above a conveying means that gradually slows, which naturally ends in this configuration of the staggered products, then to be separated into channels. EP1537037 thus proposes a frame that is movable to agitate the loose flow and then to force the transition into separate predefined channels. U.S. Pat. No. 5,235,996 for its part finally proposes a solution of longitudinally alternating movable walls, in the extension of the walls that define the channels. These principles, however, do not make it possible systematically to avoid jamming.
- Therefore, there is today in the state of the art a need to improve the feeding of a machine for packaging products in matrix batches, of the bundling type, so as, in particular, to avoid the failures caused by falling, jamming, or the like, that happen during the transition from a single-line distribution of the products to a transverse distribution of the products.
- The invention thus aims to propose a solution in which the feeding of a batch packaging machine is reliable, and also makes possible, as far as practicable, an overall configuration that is versatile and not very bulky.
- To do this, the invention proposes using a transfer of products during which each product is referenced and whose position can thus be known and controlled individually. After preparation of the products, the latter are picked up and moved in a controlled way to the input zone of the bundling packaging station, then are deposited there, distributed transversely. Thus avoided is a conveying by conveyor belt on which the products rest and on which their position and stability are in practice not strictly known.
- The invention thus has as its object a packaging device, for batch packaging of products, of the bottle, jar, canister, or the like type, within which, for their packaging, the products move along a conveying direction, said batches having, transversely to said conveying direction, at least two products, said device comprising a feed means, to receive products traveling in a single line in the area of an upstream pick-up zone and to bring them to the area of a deposit zone for their subsequent packaging.
- This device is characterized in that the feed means comprises, on the one hand, in the pick-up zone, an individual transfer means of the products arriving in a single line, and, on the other hand, at least one collector that is movable and position-controlled, for receiving then moving in a position-controlled way at least one product from the transfer means to the deposit zone, the device further comprising a conveyor in the deposit zone on which the at least one collector deposits the at least one product that it previously picked up in the pick-up zone.
- The invention also has as its object a processing machine using this device, namely a machine for processing products, of the bottle, jar, canister, or other container type, comprising a group for individual preparation of products, delivering finished and individually-referenced products one after the other in a single line.
- This machine is characterized in that it further comprises, mounted downstream from said preparation group and receiving the products that the preparation group dispenses, a packaging device as defined above.
- The invention also has as its object a method used by this device, namely a method for feeding a device for packaging products as described above, within which they move in a conveying direction during their batch packaging.
- This method is characterized in that the products are transferred in an individually-referenced way from an upstream pick-up zone where the products arrive in an individually-referenced way one following the other to a deposit zone in the area of a conveyor where they then travel in several columns for their packaging.
- The invention will be better understood as a result of the description below, which is based on possible embodiments, explained in a way that is illustrative and in no way limiting, with reference to the accompanying figures, in which:
-
FIG. 1 diagrams a feeding with a shuttle traveling on a closed-circuit rail between a labeling module and a bundling module; -
FIG. 2 shows a feeding with an alternate circuit to the one inFIG. 1 ; -
FIG. 3 illustrates an embodiment where each collector can pick up simultaneously several products and deposit them at the input of an accumulation of channels; -
FIG. 4 shows a piece of equipment to be mounted downstream from a preparation group, comprising a screw for spacing and a transfer wheel; -
FIG. 5 shows a principle with a reverse sense of travel to that ofFIG. 4 ; -
FIG. 6 shows the loading of a multi-product collector from a transfer wheel; -
FIG. 7 diagrams the traditional architecture of a piece of bundling packaging equipment; -
FIG. 8 shows a possibility of travel for the rail on which the collectors travel, with several segments. - The invention therefore first of all has as its object a
packaging device 1, forbatch 2 packaging ofproducts 3, of the bottle, jar, canister, or the like type, within which, for their packaging, theproducts 3 move along a conveyingdirection 4, saidbatches 2 having, transversely to said conveyingdirection 4, at least twoproducts 3, saiddevice 1 comprising afeed means 5, to receiveproducts 3 traveling in a single line in the area of an upstream pick-up zone 6 and to bring them to the area of adeposit zone 7 for their subsequent packaging. - The
products 3 are therefore prepared upstream from thepackaging device 1, particularly in a preparation group ofproducts 3. Theseproducts 3 therefore arrive in thepackaging device 1 to be packaged there for shipping. Thepackaging device 1 therefore generally does not modify the structure itself of theproducts 1, which is done upstream. Thus, upstream from thepackaging device 1, theproduct 1 is produced by making the container itself, filling it, capping it, labeling it. The sequence of the steps can vary: making the container, labeling, filling, then capping, or making the container, filling, capping, then labeling, etc. - The
packaging device 1 is therefore differentiated from the upstream modules in that it does not intrinsically transform theproducts 3 individually. Generally, thepackaging device 1 therefore receives finishedproducts 3, ready to be packaged inbatches 2, in the form of a bundle, case, etc. Generally, it receives theseproducts 3 from the last module ensuring the production of the finishedproduct 3, otherwise called preparation group. - This preparation group can therefore be the final module itself, namely a
labeling module 18 or a filling-capping module. The preparation group can also include a series of modules still upstream, such as filling, blow molding, capping, indeed the entire series of modules necessary to produceproducts 3 from preforms, etc. In a preferred way, the module just before thepackaging device 1 is alabeling module 18 or a filling-capping module. - As a result of a feed means 5, the
packaging device 1 therefore receives theproducts 3 from the output of a preparation group, which dispenses finishedproducts 3 individually, and which must be put into groups for shipping. - The
packaging device 1 can preferably be a packaging by bundling, where afilm 16 surrounds abatch 2 ofproducts 3. Thepackaging device 1 then comprises a feed means 5 to recover theproducts 3 that have just been finished and to process them by bundling during which afilm 16 is wrapped aroundseveral products 3 to form from them a self-supported group. Thepackaging device 1 must therefore ensure both the movement of theproducts 3 from the preparation group to the subsequent packaging processing modules and the organization of theproducts 3 intobatches 2. - The
batches 2, downstream from the feed means 5, have in particular at least one row ofseveral products 3 that are transverse to said conveyingdirection 4, and even several columns ofproducts 3 extending in theconveying direction 4. Thebatches 2 can be organized in staggered rows, with oneproduct 3 overlapping between twoother products 3 beside it, or in a non-staggered matrix. Of course, thepackaging device 1 can be adapted to process several rows ofparallel batches 2 in theconveying direction 4. - The feed means 5 therefore recovers the finished
products 3 in a pick-up zone 6, in the area of the preparation group, and brings them into adeposit zone 7, from which they will be packaged in bundles. Theproducts 3 are held and positioned individually within the preparation group upstream from thepackaging device 1. - According to the invention, the feed means 5 comprises, on the one hand, in the pick-up
zone 6, ameans 8 for transfer individually of theproducts 3 arriving in a single line, and, on the other hand, at least onecollector 9 that is movable and position-controlled, for receiving and then moving in a position-controlled way at least oneproduct 3 from the transfer means 8 to thedeposit zone 7, thedevice 1 further comprising aconveyor 10 in thedeposit zone 7 on which the at least onecollector 9 deposits the at least oneproduct 3 that it previously picked up in the pick-upzone 6. - The transfer means 8, which receives the
products 3 individually from the preparation group, can take the form of a rotating star between the fingers of which theproducts 3 can come. The at least onecollector 9 interacts with this transfer means 8 to pick up theproducts 3 that it has. Theproducts 3 therefore pass from the transfer means 8 to thecollector 9 while being continuously referenced, unlike configurations in which, for example, a conveyor belt brings a line ofproducts 3 into acollector 9, and where theproducts 3 are therefore not brought to thecollector 9 in a position-controlled and referenced way individually. - The feed means 5 therefore manages the
products 3 by systematically controlling the position thereof, so that it is possible, at any time, to know the exact position of eachproduct 3 in the feed means 5. This tracking of the position is ensured successively at least by the transfer means 8 as well as by thecollectors 9. - A mechanical interaction is therefore provided between the
collector 9 and eachproduct 3 that it carries, so that the position of thecollector 9, which is known, directly gives the information of the position of theproducts 3. - As will be further described later, the speed of the
products 3 is ensured by the transfer means 8, which prepares the spacing between thesuccessive products 3. It is found in the pick-upzone 6, where theproducts 3 travel one after the other with a controlled spacing and in a position-controlled way. Thecollector 9 ensures, for its part, at least the movement from the pick-upzone 6, directly in the area of the transfer means, in which the position of eachproduct 3 is known, to aconveyor 10 in thedeposit zone 7. The referencing of theproducts 3 is therefore never lost in the feed means 5, in particular since theproducts 3 of the transfer means 8 are directly picked up by position-controlledcollectors 9. - A carrying means or star is generally provided at the output of the preparation group, in which the
products 3 are held and referenced individually. As will still be presented in detail below, this carrying means of the preparation group and the transfer means 8 of the packaging device can be the same means. - The
collectors 9 and the upstream transfer means 8 are therefore coordinated, and eachproduct 3 is followed in position from said transfer means 8, which, as has already been mentioned, can be the carrying means located at the output of the preparation group, or at least synchronized with it. The specific processing of eachproduct 3 is thus known and controlled all along the process, without loss of control at the time of the packaging step. - The fact of position-referencing the
product 3 from the pick-up to the deposit makes it possible to do without conveyors with conveyor belts in which the products can fall or be positioned in a problematic way for a column layout in the conveyingdirection 4. The knowledge and control of the position of thecollectors 9 also make it possible to deposit theproducts 3 in a position-controlled way, and therefore, for example, to deposit them immediately at a location that corresponds to the subsequent position of theproduct 3 in abatch 2. - According to a possible additional characteristic, the
packaging device 1 has adownstream accumulation zone 11, within which theproducts 3 can be accumulated in several adjacent columns that extend along the conveyingdirection 4 after having been deposited by the feed means 5, so as to ensure that each row that is transverse to the conveyingdirection 4 is complete and has all of theproducts 3 necessary to form abatch 2. - This
downstream accumulation zone 11 can be achieved in particular by means of a series of two belts, the first of which travels faster and on which theproducts 3 are deposited, longitudinal separations delimiting a plurality of channels in which theproducts 3 are then placed in adjacent columns, for a subsequentseparation creating batches 2 of at least one row of severaltransverse products 3. Thecollectors 9 therefore bring theproducts 3 into the extension of the channels delimited by the successive separation walls. The accumulation then makes it possible to ensure that thesuccessive products 3, in the conveyingdirection 4, are properly against one another and in sufficient number to form acomplete batch 2, in particular in the case where eachbatch 2 must have several transverse rows against one another. - According to another possible additional characteristic, the
packaging device 1 comprises, on the one hand, amain conveyor 12, which moves theproducts 3 for their packaging within said device downstream from the feed means 5, and, on the other hand, adeposit conveyor 13 forming theconveyor 10 on which the at least onecollector 9 deposits the at least oneproduct 3 that it picked up, the advancing of thedeposit conveyor 13 being synchronized with the successive depositing ofproducts 3 on it that is ensured by the at least onecollector 9. - The
main conveyor 12 ensures the movement of theproducts 3 during their processing by packaging of the bundling type, and can have separate segments, in particular for a circulation within aselection module 22, acycler module 14, a covering means 15, and even a heat-shrinking tunnel forfilm 16. - It is therefore proposed here to have, on the one hand, a
deposit conveyor 13, dedicated to receiving theproducts 3 deposited by thecollectors 9, and, on the other hand, amain conveyor 12, downstream from thedeposit conveyor 13 that feeds it. The operation of thedeposit conveyor 13 can thus be synchronized with the depositing ofproducts 3 by thecollectors 9, so that they successively form the transverse rows of thebatches 2, while themain conveyor 12, in particular if it is the conveyor ensuring the transfer of the products within the shrink tunnel, continues to operate, for example, continuously. Thedeposit conveyor 13 therefore advances by a distance corresponding to oneproduct 3 in the longitudinal direction of the conveyingdirection 4 to bring forth a free receiving surface for the following row. The advance of thedeposit conveyor 13, dedicated to the depositing, can thus be calculated so that the rows of thesame batch 2 come into contact with one another, but so that the rows ofdifferent batches 2 are separated. - It will be understood that it is advantageous to deposit the
products 3 as close as possible to the covering, to benefit most from the position-referencing that is ensured by the feed means 5 and to avoid the portions of conveyors on which theproducts 3 cannot be referenced. - The
packaging device 1 preferably takes the form of a piece of bundling packaging equipment, where thesuccessive batches 2 are wrapped with afilm 16. Such apackaging device 1 comprises at least, before the shrink oven, a covering means 15 to wrap thesuccessive batches 2 withfilm 16. The correct spacing of thebatches 2 in the conveyingdirection 4 can be ensured by the sequence of aselection module 22 and acycler module 14, which aim essentially to bring to the input of the coveringmodule 15 compact and complete and correctly-spacedbatches 2. - The feed means 5 can then deposit the
products 3 upstream from these two modules, which will be responsible for delimiting thebatches 2 longitudinally. The formation of thebatches 2 can then be ensured at the time of the depositing of theproducts 3 by the feed means 5. In these cases, thepackaging device 1 comprises a module designed to separate, longitudinally from one another in the conveyingdirection 4, theproducts 3 organized in adjacent columns extending in said direction, so as to formsuccessive batches 2, of thecycler module 14 or theselection module 22 type, the feed means 5 depositing theproducts 3 at the input of said module, optionally in the area of adeposit conveyor 13. - The feed means 5 can also deposit the
products 3 inbatches 2 directly, particularly by depositing them in the same location in thedeposit zone 7, the disengagement of theproducts 3 previously deposited being ensured by the movement of thedeposit conveyor 13, and even by depositing them at different locations to make up abatch 2 whoseproducts 3 will be moved only once saidbatch 2 will have been completed. If thebatches 2 are organized directly during the depositing by the feed means 5, it is conceivable that thecollectors 9 release theproducts 3 directly in the area of the coveringmodule 15, where they will be wrapped withfilm 16 once thebatch 2 is complete. In these embodiments of thepackaging device 1, it comprises a covering means 15, where theproducts 3 that are organized insuccessive batches 2 are wrapped withfilm 16 for a subsequent restraint intended for the formation of self-supported bundles held by saidfilm 16, the feed means 5 depositing theproducts 3 at the input of said covering means 15, optionally directly on thefilm 16 already partially extended over the belt that then forms themain conveyor 12. Thismain conveyor 12 can be driven with a continuous movement, the timing of the depositing of thesuccessive products 3 then being coordinated to form thebatches 2 directly on it. - The
packaging device 1 can also have other characteristics that are presented in detail below. - According to a possible additional characteristic, the at least one
collector 9 is set in motion between the pick-upzone 6 and thedeposit zone 7 as a result of a linear motor principle. Thecollector 9 is therefore carried on a shuttle whose movement is caused by a linear motor principle. Such a shuttle therefore rests on a base with which a magnetic interaction is produced that moves the shuttle in one direction or the other along the base orrail 21. The speed of thecollector 9 is therefore variable and its position is known specifically, which contributes to controlling the position of the products 3: the position of eachcollector 9 is known, and, since thecollector 9 controls the position of the at least oneproduct 3 that it carries, and even that it holds firmly, the position of eachproduct 3 is therefore known at least relative to the frame of theconveyor 10. - The
packaging device 1 is therefore equipped with a control unit that guides the movement of thecollectors 9 through the linear motor on which they are mounted. As is also mentioned elsewhere, this guiding unit preferably also controls the movement of theconveyor 10 on which theproducts 3 are deposited, and this in a coordinated way with the movement of thecollectors 9. - According to another possible characteristic, the
packaging device 1 further comprises aguide rail 21 with a closed loop portion, the at least onecollector 9 taking the form of a shuttle traveling on saidrail 21, between the pick-upzone 6 and thedeposit zone 7. Therail 21 therefore ensures the linear motor function and extends preferably essentially horizontally, i.e., parallel to the plane of theconveyor 10. The shuttles carrying thecollectors 9 therefore travel along thisrail 21, which makes it possible for them to arrive both in the pick-upzone 6 and in thedeposit zone 7. The closed portion of thisrail 21 makes it possible to perform both the coming and the going. - As a result of using a linear motor principle, the
collectors 9 can be moved in relation to one another and can be moved separately. The position of eachcollector 9 is controlled individually. - In advantageous embodiments, the circuit of the
rail 21 comprises an active portion that serves to connect, in one direction and in the other, the pick-upzone 6 and thedeposit zone 7, as well as at least one switch making it possible to connect said active portion to other portions of the circuit, asFIG. 8 shows. - The active portion therefore makes it possible for the
collector 9 to travel to fulfill its conveying function between the pick-upzone 6 and thedeposit zone 7. The other portions can be used, for example, to switch offproducts 3 by bringing thecollectors 9, which are identified as carrying them, onto a particular segment. These other portions can also be used to swapcollectors 9, and therefore to remove usedcollectors 9 for maintenance, and even to switch offcollectors 9 that become unsuitable due to a change of format, or else to temporarily leavecollectors 9 waiting for a new format ofproducts 3, etc. Therail 21 can thus be provided itself with a zone for accumulating empty orfull collectors 9, to ensure an accumulation between the preparation group and theconveyor 10. - Thus, in certain embodiments, the circuit of the
guide rail 21 further comprises at least one portion dedicated to receiving waitingcollectors 9, particularlycollectors 9 coming from the pick-upzone 6 but not yet being authorized to go into thedeposit zone 7, orcollectors 9 coming from thedeposit zone 7 but not yet being authorized to go into the pick-upzone 6, orelse collectors 9 designed for anotherproduct 3 format. - According to another possible additional characteristic, the circuit of the
guide rail 21 further comprises, connected to the active portion, an ejection portion on which thecollectors 9 are brought to circulate that are conveying at least onenon-compliant product 3 collected in the pick-upzone 6, to prevent saidproduct 3 from being brought into thedeposit zone 7. Such a portion thus makes it possible to manage the presence ofnon-compliant products 3 downstream from the transfer means 8 and that are therefore picked up in thecollectors 9. - According to another possible additional characteristic, the at least one
collector 9 has a capacity that corresponds to asingle product 3, so that acollector 9 can take away only asingle product 3 at a time from the pick-upzone 6 to thedeposit zone 7, the feed means 5 comprising particularly a plurality ofcollectors 9, preferably at least one group ofcollectors 9 formed by asmany collectors 9 as the number ofproducts 3 that form one row of abatch 2 that is transverse to the conveyingdirection 4, and even as the number ofproducts 3 that form several aligned rows, intended to contribute toseveral batches 2 that are aligned transversely. - One of the advantages of the
collectors 9 that process theproducts 3 individually is that the possible ejection off the useful portion of therail 21 can be done precisely, while avoiding taking offproducts 3 that are compliant, but mounted on acollector 9 that must be taken off because it comprises at least onenon-compliant product 3. Another advantage is that in case of a shortfall on the transfer means 8, the precedingcollector 9 can be moved, and thefollowing collector 9 remains in waiting mode. It will thus be understood that generally, the control of theproducts 3 individually ensures an improved, more efficient, treatment process, since eachproduct 3 undergoes only the operations that relate to it. In other words, the processing of eachproduct 3 is suited specifically to it. - According to another possible characteristic, the at least one
collector 9 has a capacity ofseveral products 3, so as to be able to pick up in the pick-upzone 6 and bring to the deposit zone 7 a plurality ofproducts 3 each time, preferably asmany products 3 as the number ofproducts 3 that form a row of thebatch 2 that is transverse to the conveyingdirection 4, and even several aligned rows intended forseveral batches 2 beside one another. Themultiple products 3 that thecollector 9 can take therefore arrive one after the other in thecollector 9, and, asFIG. 6 shows, thecollector 9 is moved gradually to put an open receiving receptacle opposite eachnew product 3 to be recovered from the transfer means 8. The advantage of a multiple collector is in particular to be able easily to deposit all of theproducts 3 simultaneously in thedeposit zone 7. - According to another possible additional characteristic, the feed means 5 comprises a plurality of
collectors 9 that are movable in relation to one another, particularly to come near or move away on theguide rail 21. It is thus possible, for example, to group thecollectors 9 beside one another to handle their depositing simultaneously. - Since the
collectors 9 generally deposit theproducts 3 at the same location in the longitudinal direction, it is preferable that all of theproducts 3 that form the same transverse row be effectively deposited at the same time, which simplifies the adjustment of the longitudinal movement of theconveyor 10. In the cases where the entirety of theproducts 3 of a transverse row is contained inseveral collectors 9, thesecollectors 9 can, to deposit theproducts 3, be grouped against one another and then deposit theproducts 3 simultaneously. - Of course, this is applicable to the cases where the depositing is done for
products 3 that are then distributed in more than onebatch 2. - According to another possible additional characteristic, the feed means 5 comprises, to furnish the
products 3 individually to the at least onecollector 9, in the area of the pick-upzone 6, ameans 8 for transfer ofproducts 3 individually, of the star type, the speed of theproduct 3 in said transfer means 8 and the speed of thecollector 9 being parallel, during the transition from one to the other, which is in particular illustrated inFIG. 6 , and optionally also in the same direction and range. Theproduct 3 therefore does not undergo any variation in either movement or speed during its introduction into thecollector 9. Theproducts 3 therefore go from a means of movement in which they are referenced individually, namely the transfer means 8, to another means of movement in which they are once again referenced individually, namely acollector 9. This transition from one to the other is done without impact or pressure for theproduct 3, which is therefore not destabilized and does not risk falling or being broken. - The device is thus differentiated from the equipment where the
products 3 arrive in a collector with a speed that is perpendicular to the subsequent movement of thecollector 9, and where theproducts 3 then undergo impacts that can lead to falls. - As
FIG. 6 shows, at the time theproduct 3 goes from the transfer means 8 to thecollector 9, it is driven by a movement of the same speed as the speed that thecollector 9 has for heading toward thedeposit zone 7. Thecollector 9, in particular when it is proportioned forseveral products 3, can therefore have a continuous movement without a risk of jamming. - The invention also has as its object a
machine 17 forprocessing products 3, of the bottle, jar, canister, or other container type, comprising a group for preparation ofindividual products 3, delivering finished and individually-referencedproducts 3 one behind the other in a single line. - As has already been described above, the preparation group for
products 3 consists in at least the final step of production of theproducts 3 themselves, and even at least one other upstream step of it. The group for preparation ofproducts 3 thus comprises in particular, for example, a plastic bottle blow-molding module, a filling module in which theproducts 3 are filled, a capping module where theproducts 3 are capped, and/or alabeling module 18 within which a label is affixed on eachsuccessive product 3 individually, particularly by gluing or printing. The preparation group can thus consist essentially in afinal labeling module 18, or else any finalizing module ofproduct 3 or any combination of such modules. - According to the invention, this machine further comprises, mounted downstream from said preparation group and receiving the
products 3 that the preparation group dispenses, apackaging device 1 as described above. At the output of the preparation group, theproducts 3 are therefore individually position-referenced and are fundamentally finished and ready for packaging intobatches 2 by thepackaging device 1 whose feed means 5 preserves the individual referencing of theproducts 3. - In advantageous configurations, such as the ones diagrammed in
FIGS. 1 to 5 , the preparation group and thepackaging device 1 are arranged so that, seen from above, the feed means 5, between the preparation group and the following elements of thepackaging device 1, extend approximately perpendicular to the conveyingdirection 4 of theconveyor 10 in thedeposit zone 7, or of themain conveyor 12. More particularly, the preparation group is therefore as housed between, on the one hand, the feed means 5 and, in perpendicular, the equipment following thepackaging device 1. This ends then in a configuration where thecollectors 9 are easy to access in case of a need for maintenance, and where an extremely compact configuration can be obtained to contain both thepackaging device 1 and the upstream preparation group. - The
collectors 9, between, on the one hand, the preparation group, and, on the other hand, the following modules of thepackaging device 1, such as theselection module 22 orcycler module 14 or the covering means 15, are therefore driven by a movement that is essentially perpendicular to the conveyingdirection 4 of themain conveyor 12. The overall arrangement therefore forms a compact machine, and the various functional groups therefore remain accessible. Thepackaging device 1 thus forms, seen from above, an L configuration, in the hollow of which is found the preparation group. - According to a possible additional characteristic, the processing machine comprises an ejection means to remove, before the pick-up by the feed means 5, the
non-compliant products 3 at the output of the preparation group. This ejection is therefore positioned preferably in the area of the carrying means at the output of the preparation group, since theproducts 3 are referenced there and known by position individually. Theproducts 3 detected upstream as non-compliant are thus ejected and it is avoided thatnon-compliant products 3 are picked up by thecollectors 9, which ensures that theproducts 3 provided by the feed means 5 are all compliant. - In particular embodiments, the transfer means 8 of the
packaging device 1 forms the output of the preparation group and thus itself ensures the transfer ofproducts 3 between, on the one hand, the preparation group, and, on the other hand, thepackaging device 1, more particularly directly in the area of thecollectors 9 of the feed means 5. The transfer means 8 thus forms both the output of the preparation group and the input of the feed means 5 of thepackaging device 1. The processingmachine 17 thus ensures itself and, in an integrated way, on the one hand, the function of the preparation group, namely the labeling or final filling-capping, and also even upstream preparation functions, and, on the other hand, the function of packaging of theproducts 3 that are dispensed. Theprocessing machine 7 is therefore provided with one and the same means processing theproducts 3 in an individually-referenced way at the interface between thepackaging device 1 and the preparation group. Thefinished products 3 at the output of the preparation group therefore travel on a transfer means 8 in the area where thecollectors 9 of the feed means 5 come to pick them up directly. The continuity of the referencing is thus ensured. In other words, the feed means 5 of thepackaging device 1 takes theproducts 3 directly at the referenced output of theproducts 3 of the preparation group. - According to a possible additional characteristic, the processing
machine 17 has, on the one hand, awheel 19, for referenced transfer, positioned at the output of the preparation group and delivering theproducts 3 individually, and, on the other hand, ascrew 20 between saidwheel 19 and the transfer means 8 of the feed means 5, saidscrew 20 and the transfer means 8 being synchronized. The referencedtransfer wheel 19 can take the shape of a star at the output of thelabeling module 18 that forms the preparation group. Thescrew 20 is therefore synchronized with the movement of the transfer means 8 downstream, which brings the products to thecollectors 9 of the feed means 5. It makes it possible either to move theproducts 3 in a referenced way from the output of the upstream preparation group to the transfer means 8, or to recreate a referencing. - In certain embodiments, the
screw 20 is also synchronized with thetransfer wheel 19 of the output of the preparation group, so as to guarantee a position-controlled movement of theproducts 3 from the output of thelabeling module 18 or preparation group, to the pick-up by the at least onecollector 9. The position control of each product is therefore optimal, and the process is efficient, suited to eachproduct 3. - It is also conceivable that the processing
machine 17 has anupstream accumulation zone 23 for theproducts 3 downstream from thewheel 19 and upstream from thescrew 20, where theproducts 3 are freely accumulated in a single line to form a continuous flow even if the flow of enteringproducts 3 is interrupted, for example considering an ejection, upstream, ofnon-compliant products 3. - The invention also has as its object a method using the invention as described above, namely a method for feeding a
device 1 for packaging products as described above, within which they move in a conveyingdirection 4 during their packaging inbatches 2, particularly by bundling. - According to the invention, the
products 3 are transferred in an individually-referenced way from a pick-upzone 6 upstream where theproducts 3 arrive in an individually-referenced way one following the other to adeposit zone 7 in the area of aconveyor 10 where they then travel in several columns for their packaging. Theproducts 3 are therefore deposited in successive longitudinal columns directly by the feed means 5. Their correct positioning for bundled packaging bylots 2 is therefore controlled and guaranteed, unlike feeding solutions based on conveyors of the moving-belt type. - According to a possible additional characteristic,
several products 3 are simultaneously deposited on theconveyor 10 by eachcollector 9 in thedeposit zone 7, in particular all of theproducts 3 forming a complete row transverse to the conveyingdirection 4 and thus participating in the making of at least onebatch 2. Thecollectors 9 therefore release at the same time all of theproducts 3 that form a transverse row in thebatch 2, which makes it possible to simplify the synchronization of the movement of theconveyor 10 ordedicated deposit conveyor 13. The depositing by thecollectors 9 can thus form the successive transverse rows of asingle batch 2 or ofseveral batches 2 at the same time, in the cases where thepackaging device 1 processes several columns ofbatches 2 that are beside one another. At the time of the depositing, theproducts 3 in thecollectors 9 therefore reproduce the shape of the transverse row. - In the cases where a
collector 9 does not alone convey the entirety of theproducts 3,several collectors 9 can be brought near to one another to reproduce, together, the configuration of the row of thebatch 2. - According to another possible additional characteristic, the movement of advance of the
conveyor 10 on which theproducts 3 are deposited and the frequency of depositing theproducts 3 on it are coordinated, so that theconveyor 10 advances by the equivalent of one transverse row as soon as such a row has been deposited, to make room for the next row in thebatch 2 or else as soon as thecollectors 9, intended to transfer together an entire row of afuture batch 2, have deposited theproducts 3 that it contained. - The method can also have other technical characteristics that are presented in detail below.
- According to a possible additional characteristic, the method comprises an ejection step, after the pick-up of the
product 3, during which acollector 9 comprising at least onenon-compliant product 3 is discharged from the circuit connecting it to thedeposit zone 7. The ejection ofnon-compliant products 3 is therefore done in the area of thecollectors 9, as a result of the design of the circuit on which they travel and as a result of their individual guiding. Since the position of eachproduct 3 is known, it is possible to avoid supplyingdefective products 3 into thebatches 2. - According to another possible additional characteristic, after the pick-up of
products 3, thecollectors 9 are grouped to form together a group ofproducts 3 that are aligned and that are to be simultaneously deposited, particularly a row of abatch 2, which makes it possible in particular to use one deposit step for the group ofproducts 3, and this in a simultaneous way. - In the embodiment illustrated in the accompanying figures, the
packaging device 1 takes the form of a bundling device, in which, for the bundling operation itself, theproducts 3 travel on amain conveyor 12 in the form ofbatches 2, in a conveyingdirection 4. Abatch 2 hasseveral products 3 aligned in a row that is transverse to the conveyingdirection 4, and generally alsoseveral products 3 aligned in the conveyingdirection 4. Abatch 2 therefore has a matrix configuration, with or without staggering, theproducts 3 then being aligned compactly both in the conveyingdirection 4 and transversely. AsFIG. 7 shows, thebatches 2 thus move in thepackaging device 1 while being spaced from one another in the conveyingdirection 4. In such apackaging device 1, for the bundling operation, abatch 2 ofproducts 3 generally is wrapped with aplastic film 16, then travels into a heated tunnel where thefilm 16 shrinks and then holds theproducts 3 against one another. - The
products 3 are generally bottles, jars, etc., filled and labeled in a preparation group, before this secondary packaging step that, for its part, aims to group them and bind them in self-supported bundles. Upstream from thispackaging device 1, therefore, there is equipment that produces theproduct 3 itself, generally ending with a labeling step. Such alabeling module 18 generates at its outputindividual products 3, one after the other, generally by means of a rotating carousel, thepackaging device 1 producing, for its part,successive batches 2 each comprisingseveral products 3. At the output of thelabeling module 18, theproducts 3 therefore travel one following the other in the direction of advance. Alabeling module 18 using rotating elements, of the carousel type, on the periphery of which theproducts 3 are located, is, for example, described in US2010276028. - Generally, the
labeling module 18 comprises at least, at its output, one means for carrying theindividual products 3, such as a rotating star between the fingers of which theproducts 3 are found. At the output of thelabeling module 18, theproducts 3 are therefore moved in a controlled manner individually by this carrying means, unlike, for example, a loose carrying solution where the position of eachproduct 3 is not known precisely, or even a conveying by column on a belt, then not controlled because it does not prevent the sliding of theproducts 3 and even their falling, being unresponsive to their absence, etc. - The
packaging device 1 is thus equipped with a feed means 5, which ensures its supplying ofproducts 3 from the output of thelabeling module 18. AsFIG. 1 shows, the organization of theproducts 3 must go from an organization of a single column at the output of thelabeling module 18 or preparation group to an organization of several columns for packaging in thepackaging device 1 in the form ofbatches 2 based on rows ofseveral products 3 each.Several batches 2 can further be found aligned transversely to the conveyingdirection 4. Going from the single-line configuration to the multi-line configuration is achieved by means of the feed means 5, as it is described here. - The feed means 5 thus comprise at least one
movable collector 9, thiscollector 9 being able to pick up and move at least oneproduct 3 from the pick-upzone 6, where theproducts 3 still travel in a single line, to thedeposit zone 7 where theproducts 3 are organized in several columns on aconveyor 10 that takes them to be packaged.FIG. 1 shows, for example, afeeding device 5 that comprises only onecollector 9, thiscollector 9 being able in turn to receive asingle product 3 and to place it in the corresponding column. - The
collector 9 of the feed means 5 is movable in a controlled and known way, which makes it possible to know at each moment with precision the position of the at least oneproduct 3 that it moves. Thecollector 9 thus comprises, for example, for eachproduct 3 that it must move, a receptacle to simply at least hold theproduct 3 by the body, or else a gripper to grab strictly speaking eachproduct 3, at its neck or elsewhere. - The position of the
collector 9, when it lets go of theproducts 3 in thedeposit zone 7, is therefore known and controlled, at least in the direction that is transverse to the conveyingdirection 4. This thus makes it possible to guarantee the transverse position of the at least oneproduct 3 brought by the at least onecollector 9 and therefore to deposit said at least oneproduct 3 immediately at the proper location in the transverse direction. Actually, the makeup of the batches necessitatesproducts 3 distributed transversely to the conveyingdirection 4, which such acollector 9 can achieve by a known and controlled position, designed to ensure a referencing of the at least oneproduct 3 that it moves. Thecollectors 9 are actually preferably equipped with mechanical means to pick up eachproduct 3 separately, and are mounted on a movable shuttle in a controlled way. - The
product 3 is therefore referenced between the pick-upzone 6, which can be directly the output of the preparation group, and thedeposit zone 7, from which the secondary packaging operation itself is performed. It is thus possible to control exactly the location where theproduct 3 will be deposited on theconveyor 10, i.e., in particular in the area of whatever longitudinal column. Thus, as a result of the control and of the referencing of theproduct 3 during the travel and during the depositing in thedeposit zone 7, it is possible to deposit aproduct 3 intended to form thefirst product 3 of a transverse row of abatch 2, then, with anothercollector 9, to deposit theproduct 3 intended to form thesecond product 3 of such a row, then that for thethird product 3 of the row, etc. It is, of course, possible to simultaneously release all of theproducts 3 forming a transverse row of abatch 2. Acollector 9 can actually collectseveral products 3 successively while receiving them beside one another in a direction that is then transverse to the conveyingdirection 4, so that the simultaneous depositing of all of theproducts 3 immediately leads to the making of a transverse row ofseveral products 3, to create, by grouping several of them, at least onebatch 2, and evenseveral batches 2 aligned transversely to the conveyingdirection 4. The referencing of theindividual products 3 by means of themovable collector 9 in a controlled way thus immediately ensures the controlled depositing in successive longitudinal columns. - The
products 3 are released by thecollectors 9 in the area of adeposit zone 7 in which aconveyor 10 is found. They are deposited on theconveyor 10 that then introduces them into the core of the sequence of the packaging steps: traveling in separate channels; separation of the groups of transverse rows that define abatch 2; synchronization with the covering or wrapping; or covering directly. Theproducts 3 are thus deposited at the latest during the covering itself, or wrapping by thefilm 16, directly at the input of one of these steps. As will be further described below, the release of theproducts 3 can therefore, depending on the configurations, be done at different locations before the wrapping of thebatch 2 with thefilm 16 in the covering means 15: either at the input of a conveying in channels; or at the input of a referencing cycler; or directly at the input of the covering table 15. - A longitudinal accumulation can be provided downstream from the depositing by the
collector 9, and even directly in the area of thedeposit zone 7. Traveling channels are then preferably accommodated preferably by means of longitudinal walls to prevent the overlapping of theproducts 3 in the form of a staggered organization that would cause the advantage of the transverse position-controlled depositing to be lost. Theproducts 3 are then accumulated in these channels of longitudinal columns, which guarantees the presence of a sufficient number ofproducts 3 in the conveyingdirection 4 to make upbatches 2 formed by several transverse rows. - Such a
downstream accumulation zone 11, downstream from the transfer, by the fleet ofcollectors 9 that comprises the feed means 5, makes it possible in particular to avoid gaps in the continuous matrix arrangement of theproducts 3 as is required for the packaging of bundledbatches 2. It also makes it possible to use configurations where the number ofproducts 3 that eachcollector 9 conveys does not correspond to the number ofproducts 3 of a transverse row of abatch 2. Actually, in cases of this kind, theproducts 3 of the same row are not necessarily released at the same time, and it is then useful to provide such adownstream accumulation zone 11 to complete each transverse row. - In advantageous embodiments, each
collector 9 is able to receiveseveral products 3 and to move them simultaneously toward thedeposit zone 7. Theproducts 3 are therefore received successively in such acollector 9 from the output of thelabeling module 18, preferably directly in the area of the carrying means at its star-type output. Thecollector 9 thus has single reception zones that are aligned in a direction that corresponds subsequently to the direction that is transverse to the conveyingdirection 4, or the direction of a row. Theproducts 3 of thecollector 9 are then all deposited simultaneously on theconveyor 10 in thedeposit zone 7. This assembly ofproducts 3 thus directly forms a row of thebatch 2 that is transverse to the conveyingdirection 4, and the break-up step and then organization of a flow ofproducts 3 that is initially single-line are avoided. Of course, it is possible to perform such an operation forseveral batches 2 simultaneously. - It is then enough, by a movement of the
conveyor 10 on which the row has just been deposited, to release it to be able to receive theproducts 3 from thenext collector 9. Preferably, after depositing theproducts 3 that are intended to form a row of thebatch 2, theconveyor 10 advances by a distance that corresponds to such a row, so that the next row comes against the preceding one, which immediately, and by the sole collection-then-transfer operation, results in the formation of acompact batch 2. The spacing between thebatches 2 can be managed by lengthening the period of time that separates two successive deposits ofproducts 3 intended to form a row and/or by speeding up the movement of theconveyor 10. - Of course, it is important to prevent the defective or
non-compliant products 3 at the output of thelabeling module 18 from ending up inbatches 2 that are then wrapped withfilm 16 and packaged in thepackaging device 2, which would then render theentire batch 2 non-compliant. - The ejection of
non-compliant products 3 can be organized in the area of the output of thelabeling module 18, before the pick-up of theproducts 3 by thecollectors 9, in the area of the star carrying means. Thus, a control means is incorporated within thelabeling module 18 and makes it possible to identify theproducts 3 that are not acceptable. Since the travel of eachproduct 3 within thelabeling module 18 is followed, it is possible to eject thenon-compliant products 3 precisely, in particular in the area of the individual carrying means placed at the output of thelabeling module 18 that forms the preparation group. For example, a specific conveyor can be provided in the area of the star wheel at the output of thelabeling module 18 so that thenon-compliant products 3 are deposited there, so that only thecompliant products 3 can continue their travel to thecollectors 9. The flow ofproducts 3 downstream from this star can therefore have interruptions ormissing products 3, which correspond toproducts 3 that have been eliminated upstream, and the operation of thecollectors 9 is adjusted. - The ejection, downstream from the
labeling module 18, of thenon-compliant products 3 can also be ensured by thecollectors 9 themselves, once theproducts 3 are picked up. In particular, when thecollectors 9 arecollectors 9 provided for asingle product 3 at a time, thecollector 9 identified as moving anon-compliant product 3 can thus quite simply not be brought into thedeposit zone 7. Alternately, a complementary device can remove from the collector thedefective product 3, etc. - It is then understood that the ejection of
non-compliant products 3, upstream from the pick-up of theproducts 3 by thecollectors 9, or at least upstream from the depositing by thecollectors 9, produces gaps inproducts 3 that it is suitable to manage to avoid ending up withincomplete batches 2. - A single-line free accumulation zone can be provided, for example, for the
products 3 upstream from the feed means 5, which guarantees that the latter picks up, one after the other, continuously,products 3 that are all compliant. A multi-line accumulation zone can also be provided downstream from the multi-line release of theproducts 3 by the feed means 5. The plurality of transverse rows that are successive and in contact that thebatches 2 comprise is thus defined subsequently in this accumulation, for example by aselection module 22 or else acycler module 14, seeFIG. 7 . This downstream accumulation makes it possible for theproducts 3 that are deposited in a column after amissing product 3 to catch up with those already deposited previously. - As
FIGS. 1 to 6 show, the feed means 5 preferably recovers theproducts 3 in the area of a referenced transfer means 8 or carrying means, generally in the form of awheel 19 or star with peripheral receptacles in which each time aproduct 3 can be located at the output of thelabeling module 18. The labeling can, moreover, be performed while theproducts 3 are in this transfer means 8. Thecollectors 9, for their part, travel on a guide orrail 21 that encounters the peripheral path of the transfer means 8 to be able to perform a carrying change in the area of theproducts 3 that then go from a carrying by the transfer means 8 or wheel to a carrying by thecollectors 9, as illustrated inFIG. 6 . - During this transition from one to the other, the
collector 9 is preferably driven by a movement similar to that of theproduct 3 in thewheel 19, thus guaranteeing a fluid passage from one to the other. The receptacle in which theproduct 3 is located in the area of the wheel or star and the receptacle of thecollector 9 in which it must continue its path are therefore at least momentarily driven by a movement of the same speed, direction, orientation, and rapidity. It will be noted that a way of handling the possible absence ofproduct 3 in the wheel after the elimination of a defective product can then consist in not advancing thecollector 9 if the receptacle opposite is empty ofproduct 3, which guarantees that thecollectors 9 arriving in thedeposit zone 7 are systematically filled withcompliant products 3. - As
FIGS. 5 and 6 show, in the case where thecollector 9 is scaled forseveral products 3, once positioned for reception, it extends linearly along a tangent to the output star of thelabeling module 18, so that its movement successively brings the single reception zones to the periphery of the star. In the case where thecollectors 9 are scaled for asingle product 3 at a time, asFIG. 5 shows, for example, theguide rail 21 can, for example, have a curvature such as a half-turn, opposite the curvature of the transfer means 8, and in the area in which the transition of theproducts 3 from the transfer means 8 to thecollectors 9 is managed. The transfer into thecollector 9 can also be done while it travels on a straight portion. - It will also be noted that the
collectors 9 are therefore used in a cyclic way: after having recovered the at least oneproduct 3, thecollector 9 is then going to deposit it, then, by a return portion, come back to begin this cycle again. Therail 21 therefore has a useful closed-loop portion on which thecollectors 9 travel to move theproducts 3 between the two zones. - The integration between, on the one hand, the
labeling module 18 and, on the other hand, downstream, thepackaging device 1, and, more particularly, its feed means 5, can be arranged in different ways. For example, inFIG. 1, 2, 3 or 5 , the feed means 5 picks up theproducts 3 directly from the star orwheel 19 at the output of thelabeling module 18 or preparation group, which results in a piece of equipment incorporating both the function of the at least final making of theproduct 3, of the labeling type, and the function of packaging by bundling ofbatches 2. - As
FIG. 4 shows, the feed means 5 of thepackaging device 1 can also load theproducts 3 from a star that is different from that of the output of thelabeling module 18, which makes it possible in particular to reuse an existinglabeling module 18, without structural modification, and therefore to propose so-called “retro-fit” solutions. The feeding of thisstar 8 withproducts 3 is preferably done by means of ascrew 20 whose pitch normally corresponds to the spacing of the receiving receptacles on the star. The pitch can, of course, be scalable between the beginning and the end of thescrew 20. Such ascrew 20 makes it possible generally toreference products 3 that previously traveled possibly freely. Such a free conveying can come from the preparation group directly or after division of the single-line flow that it dispenses in several parallel flows. - The
screw 20 can here be used while being totally synchronized both with the downstream star or transfer means 8 and with the upstream carrying means, at the output of thelabeling module 18. In this case, thisscrew 20 therefore performs a referencing, spacing, and movement function, during which the position of eachproduct 3 is known and controlled from the output of thelabeling module 18 to a transfer means 8 that is then offset. - An
upstream accumulation zone 23 can also be provided, in which theproducts 3 coming out of thelabeling module 18 one after the other are conveyed freely, for example with a downstream conveyor belt that travels faster than the speed of thescrew 20. Thescrew 20 is then arranged downstream from thisupstream accumulation zone 23 and again references theproducts 3 for their pick-up in the transfer means 8 that requires that theproducts 3 be spaced from one another in a controlled way. Downstream from the star of thelabeling module 18, theproducts 3, until then referenced individually, therefore go into anupstream accumulation zone 23 in which they are grouped together in contact with one another. To again reference theproducts 3 after such a loss of control, the feed means 5 is provided preferably with ascrew 20, which defines a space between theproducts 3 and with a wheel that then ensures the transfer of theproducts 3. - The configurations where the
screw 20 is not synchronized make possible a mounting downstream from alabeling module 18 or existing preparation group, without structural modification. The use of ascrew 20 that is synchronized on the output of thelabeling module 18 necessitates a slight structural adaptation of the existinglabeling module 18. The configurations where theproducts 3 are directly picked up by thecollectors 9 at the output of thelabeling module 18 form complete, totally integrated machines that ensure both the bundling function and at least one labeling function. In the cases where the wheel of the preparation group and the wheel of the feed means 5 are not the same, the latter makes it possible to correctly reference and control eachproduct 3 before they are picked up individually, by thecollectors 9. - Generally, the feed means 5 therefore preferably ensures, on the one hand, the movement of the
products 3 from the pick-upzone 6 at the output of thelabeling module 18 to thedeposit zone 7, which can be situated at different locations upstream from a covering means 15 byfilm 16, and, on the other hand, the creation, from a continuous single-line flow ofproducts 3 one behind the other, of segments intended to form the rows of thebatches 2 that are transverse to the conveyingdirection 4, thus forming a multi-line flow. The coordination with the advance of theconveyor 10 that successively moves these rows ofproducts 3 in the conveyingdirection 4 makes it possible to obtainbatches 2, each comprising several such rows pressed against one another. - A traditional
bundling packaging device 1 has the series of various modules until the one in which thematrix batch 2 ofproducts 3 is wrapped with afilm 16, seeFIG. 7 . Thefeed device 5 can therefore furnish theproducts 3 at different locations upstream from this wrapping function: -
- at the input of a
selection module 22 whereproducts 3, previously in a column ofproducts 3 in contact with one another, are successively held by fingers that are slower than their carrying conveyor belt, to create longitudinal spaces; - at the input of a
cycler module 14, ensuring, by means of transverse bars that move faster than the carrying conveyor belt, that the longitudinal spaces are compatible with the downstream wrapping withfilm 16; - at the input of a covering means 15, optionally directly on the
film 16 during wrapping.
- at the input of a
- Of course, in each of the configurations, the
products 3 can be deposited by the feed means 5 on adedicated deposit conveyor 13, then feeding one of these inputs. - As
FIGS. 3 and 4 show, the feed means 5 preferably comprises a battery ofcollectors 9, which travel on aguide rail 21 that comprises said means. It is thus possible to drive thesecollectors 9 with movement as a result of a magnetic linear motor principle, which has the advantage of being able both to manage and control the position and speed of eachcollector 9 separately. Thecollectors 9 are therefore mounted on shuttles that are moved as a result of the linear motor principle. - The
collectors 9 are thus movable in relation to one another. Consequently, before the depositing, it is possible to bring them close to one another until they form a compact alignment, extending transversely to the conveyingdirection 4 in thedeposit zone 7 then to reproduce the row of thebatch 2 that is transverse to the conveyingdirection 4. They can then simultaneously deposit theproducts 3 that they contain, and then form a row. This is in particular useful withcollectors 9 that convey only oneproduct 3 at a time and that are not grouped together when they collect theproducts 3. - Since the exact position of each
collector 9 is known and controlled, it is also possible to provide that they release the at least conveyedproduct 3, each in turn, in the corresponding longitudinal column, then to advance thedeposit conveyor 13 for the next row only once a complete row has been deposited. - As
FIGS. 1 to 5 show, therail 21 is preferably in a closed loop, between two turnarounds that are located approximately, for the one, in the area of the output of thelabeling module 18 and, for the other, in the area of the modules that are used for thebatch 2 packaging. - The circuit that the
rail 21 forms therefore has a main portion that is used for the circulation of the collectors between the pick-upzone 6 and thedeposit zone 7 for moving theproducts 3 between these zones. This circuit can also have branches or switches to other segments that are used, for example, to switch offcollectors 9 that are defective or that convey at least onenon-compliant product 3. These other segments can also be used for an accumulation ofproducts 3, an accumulation of loaded orempty collectors 9,optionally collectors 9 that are compatible with another format, etc. The complete circuit of therail 21 can therefore be formed by, for example, a main closed loop, then of portions optionally superposed with one another, that theproducts 3 can leave and then rejoin, etc., asFIG. 8 shows. Of course, the successive loops are preferably counter-rotating. - The feed means 5 is therefore substituted for the traditional solutions of conveying by belt on which the
products 3 rest and where the transition from a single-line flow at the labeling output to a multi-line flow for packaging creates jamming or crushing problems. - It is therefore understood that in the cases where the
collectors 9 do not move the number ofproducts 3 that corresponds to a transverse row of thebatch 2, in particular the cases where thecollectors 9 each carry only oneproduct 3, it is possible to modify each time the transverse position at which thecollectors 9 release theproducts 3, so as to obtain, after several successive deposits, a configuration ofproducts 3 distributed in several longitudinal columns, adjacent transversely to the conveyingdirection 4 and forming the transverse rows. Adownstream accumulation zone 11 can then be used to ensure that the transverse rows are in proper contact with one another. - It is also possible to conceive that
collectors 9 with a capacity that is less than a transverse row of thebatch 2 are grouped together, continuously or temporarily during the cycle, to convey together asmany products 3 as at least one row must contain of them, and to deposit them simultaneously. Usingcollectors 9 that work with asingle product 3 each time meanwhile guarantees the versatility of the feed means 5, since anew batch 2 format, in terms of the number ofproducts 3 in a transverse row or in a longitudinal column, requires no structural modification, only a different adjustment of the operation of thecollectors 9. Further, an additional advantage of usingcollectors 9 having a single capacity is their removal from the circuit as soon as theparticular product 3 that they convey is not compliant. Thus, it is avoided thatproducts 3 that are in fact compliant are switched off. In the case of a removal ofnon-compliant products 3 upstream at the pick-up by thecollector 9, the use of acollector 9 having a capacity of asingle product 3 makes it possible easily to make thecollector 9 wait until the arrival of the nextcompliant product 3. - In the cases where the capacity of the
collectors 9 corresponds to the number ofproducts 3 in a transverse row, acollector 9 normally conveys each time the number ofproducts 3 for a row. It is then possible to release simultaneously all of theproducts 3 that it carries, then creating a row in a single operation. The longitudinal movement of the conveyor on which theproducts 3 are deposited then makes it possible to accumulate rows against one another in the conveyingdirection 4. - Therefore, it is as a result of the position-control of the
collectors 9 that the feed means 5 ensures the individual distribution of theproducts 3 in the direction that is transverse to the conveyingdirection 4. - Further, generally, as each
product 3 is picked up directly from thelabeling module 18, the orientation of theproduct 3 is controlled, which has a certain advantage from the moment that theproducts 3 have a special shape and/or that their orientation in thebatch 2 is important, such as, for example,products 3 with a rectangular base, etc., or elsecircular products 3, but that are to be positioned in a pre-defined way. As eachproduct 3 is picked up and preferably restrained in thecollector 9, its orientation is controlled. It is also possible to use acollector 9 with a degree of freedom around a shaft, driven or not, to modify the orientation of theproducts 3 in a controlled way between the pick-up by thecollectors 9 and their deposit. - An accumulation means can also be provided between the pick-up
zone 6 and thedeposit zone 7, for example with an accumulation table on which thecollectors 9 deposit then pick up again theproducts 3, or another means making it possible to ensure a buffer between thelabeling module 18 and thepackaging device 1. - As a result of the invention, it is thus possible to propose a solution for feeding the device for
packaging products 3 inbatches 2 by bundling, which is reliable, versatile, and which limits in a remarkable way the pieces of equipment to be provided upstream from a covering means 15 to organize the products into a multi-line flow. - Although the above description is based on particular embodiments, it is in no way limiting of the scope of the invention, and modifications can be made, particularly by substitution of technical equivalents or by a different combination of all or part of the characteristics developed above.
