Definitions
- the invention relates to an arrangement for the distribution of products on a conveyor belt at high speed.
- the invention more particularly relates to an arrangement for the distribution of products, in which the products are transported on a conveyor belt which runs along a long longitudinal direction, from an upstream arrival zone to a downstream exit zone.
- This type of arrangement is particularly useful in product packaging installations, for example in installations comprising a conveyor line for conveying products to a boxing machine, the stacking boxing machine. batches of products in crates or cartons.
- the conveying line generally comprises, upstream of the boxing machine, a conveyor belt which transports the products, with a determined spacing between two consecutive products, to a device for grouping the products, also called "aggregator", which comprises a series of mobile transport cells.
- the grouper has, opposite the carpet, an empty cell provided to receive a predetermined number of products that are stacked in the cell so as to constitute a lot.
- the cells are thus shifted progressively, notch by notches, which makes it possible to route the batches of products to the boxing machine.
- phaser a phasing device also called "phaser”.
- the arrangement usually comprises upstream of the phaseur a distribution device, also called “deviator”, for deflecting the products to perform in particular a duplication of the queue by forming a second parallel file of products.
- a distribution device also called “deviator”
- Numerous distribution devices are known from the state of the art, such as high-speed or spool type deflectors.
- An acute deflector comprises a deflection element called "acute ille" which is pivotally mounted at one of its ends around a vertical axis and is capable of pivoting between at least two extreme positions, respectively a first position wherein the needle deflects at least one produ it to a first file and a second position in which the acute ille deviates at least one produ it to a second file.
- acute angle of the deflector will, depending on its position, transversely deflect one or several products, to offset laterally with respect to the initial longitudinal file.
- the distribution sequence corresponds to an alternating deflection cycle of one product out of two, that is to say from one product to a first file then from the next product to a second
- a needle diverter as for a slide deflector
- the minimum setpoint value of the upstream spacing is determined according to the deviator, for example by adding firstly the length of the needle or the drawer in the longitudinal direction of travel of the products and, secondly, a path length which is a function of the running speed of the products and which corresponds to the switching time required for each of the deviators to move from one position to another.
- Such deviators are not particularly likely to selectively treat a line of products to start or divert, that is to say, they are not able to treat the products if they do not have spacing between them defined upstream constant value greater than or equal to a minimum setpoint value.
- the products have deviations from the upstream spacing value, particularly because of the use of conveyor belts or device for detecting and removing products. defective.
- Such devices for detecting and eliminating defective products for example due to the non-conformity of their weight, cause "holes" in the queue because of the absence of eliminated products. Consequently, an installation comprising such a device for detecting and eliminating defective products usually requires the use of other specific means, such as timing mats, to supply the deflector with regularly spaced products. between them.
- the needle diverters and the slide-out difters do not allow, by their design and operation, to process products at a very high rate, for example at rates of more than 900 products per minute.
- the state of the art is still known of distribution devices, generally called paddle deflectors, such as those described and shown in the product distribution arrangements of DE-A1-3116991 or EP -A1 -0.395.178.
- paddle deflectors such as those described and shown in the product distribution arrangements of DE-A1-3116991 or EP -A1 -0.395.178.
- Each of these documents also describes an example of application of such vane deflectors, more precisely the document DE-A1 -31 .1 6991 illustrates the case of a doubling of file tand is the document EP-A1 -0.395. 178 illustrates the case of a product deflection at 90 °.
- the distribution devices described in these documents are also not likely to selectively process a queue of products to start or to divert, ie they are not able to process the products themselves. they do not have between them a predetermined upstream spacing of constant value greater than or equal to a minimum nominal value.
- vane diverters requires the use of other specific upstream means to supply the diverter with products that are regularly spaced apart from each other.
- the invention aims in particular to remedy these drawbacks by proposing a simple, economical and effective solution allowing in particular to deflect products at a high rate. and that, moreover, they are not necessarily spaced regularly between themselves.
- the invention proposes an arrangement of the type described above, characterized in that the phaser comprises a first and a second belt that are arranged in parallel and that are driven independently, and in that each belt is controlled in an active operating state before the end of the active state of the other belt, so that the deviation of a product begins before the previously deviated downstream product has reached its final position in the second line.
- the phaser is controlled selectively, according to the said allocation sequence, so that the cleat occupies at least: a first engaged position in which the cleat comes laterally in contact with the product occupying the initial position so as to transversely deviate led it produ it from the first file, and
- a second engaged position in which, said deflected product occupying the final position in the second line, the cleat is immobilized so as to allow the deviated product to continue its displacement;
- each driving belt of the phaser carries at least one cleat and is arranged on the side of the upper face of the belt, each belt is wound on at least two drive pulleys so that a lower strand of the belt extends substantially parallel to the upper face of the belt, the cleat occupying the first and second positions engaged when it is located on the lower strand, and the phaser comprises means for driving the pulleys in rotation at the determined deflection speed;
- the phaser comprises a main axis parallel to the belt which is inclined downstream so as to form, with the long longitudinal direction of movement of the products on the conveyor belt, a determined angle whose value is between 0 ° and 90 °;
- the cleat is positioned on the belt so as to vertically present a lateral deflection face, which is intended to come into contact with the product to be deflected and which extends parallel to the longitudinal direction of movement of the products. it's the first line on the conveyor belt;
- the cleat is controlled from its second position engaged towards at least one retracted position of waiting, when having reached its final position in the second line, the deflected product is no longer transversely in contact with the lateral deflection face of the cleat;
- the belt comprises a passive operating state in which it is stopped, each cleat occupying the second engaged position or the retracted position of waiting, and the active operating state in which the belt is rotated around the pulleys of whereby a cleat moves generally transversely from the retracted retracted position to the second engaged position or from the second engaged position to the retracted retracted position;
- the belt is controlled in its active state by means of detection means, such as a sensor, positioned upstream of the phaser capable of providing a signal for detecting a product that is capable of being exploited according to the determined allocation sequence to divert products to the second file;
- detection means such as a sensor
- the retracted positions of the cleats of the first belt are offset relative to the retracted positions of the cleats of the second belt, so as to prevent a crossing of the cleats of the second belt;
- the second file comprising the deflected products is parallel to the first file;
- the belt in the engaged position, the belt is driven at a deflection speed determined in such a way that the longitudinal driving speed of the cleat is equal to the running speed;
- the second file comprising deviated products is orthogonal to the first file.

- FIG. 1 diagrammatically shows an arrangement 10 for the distribution of products Pn.
- the arrangement 10 comprises a conveyor belt 12 which runs in a longitudinal direction oriented from upstream to downstream, which corresponds generally to an orientation of the left to the right in Figure 1 in perspective.
- the arrangement 10 comprises a feeder device 14, such as a belt, which is intended to supply the conveyor belt 12 with Pn products and a distribution device 16, called a deflector.
- the belt 12 is driven at a substantially constant speed of travel V1 so that the belt 12 conveys the products Pn from an inlet zone 18 situated upstream to an outlet zone 20 situated downstream.
- the products Pn form a longitudinal queue, called first file F1 of products Pn, in which two successive products Pn are separated by a determined upstream spacing E1.
- the upstream spacing E1 between two consecutive products is greater than or equal to a minimum setpoint value determined.
- a spacing corresponds by definition to the longitudinal distance between the downstream end of a first product of a given line and the downstream end of a second product located immediately upstream. on the same file or another file, in particular parallel to that of the first product. Consequently, and as can be seen in FIG. 1, the spacing E1 corresponds to the distance between the downstream vertical face of a product Pn and the downstream vertical face of the upstream product Pn + 1, which follows immediately. .
- a distribution device 16 is arranged between the arrival zone 18 and the exit zone 20 in the path of the products Pn so as to deflect all or part of the products Pn in a predetermined allocation sequence.
- the invention is also not limited to the deviation of a product as a unitary element so that the distribution device is also likely to deflect a set of several products such as a lot.
- the distribution device 16 is constituted by at least one phaser 22 or 23 (see FIG. 7) which is controlled selectively so as to transversely deflect a product Pn on two from the first file F1 to form a second longitudinal file F2, parallel in the first file F1.
- the phaser 22 is arranged above the upper horizontal surface 24 on which the products Pn and between the arrival zone 18 and the outlet zone 20 pass.
- the phaser 22 comprises at least one cleat 26 which is driven at a deflection speed V2 and which is controlled, according to said distribution sequence, in order selectively to come into contact with at least one product Pn of the first line F1 to deviate laterally.

- FIGS. 1 to 6 a first embodiment of the phaser 22 forming the distribution device 16 according to the invention is represented.
- the phasor 22 comprises a belt 30 which is arranged on the side of the face upper 24 of the belt 12 and that it i is likely to cause in displacement at least one cleat 26.
- the belt 30 of the phaser 22 here comprises a first cleat 26 and a second cleat 28.
- the phaser 22 has more than two cleats on the belt 30.
- the belt 30 carries, on its outer face 32, the first cleat 26 and the second cleat 28 which are arranged at substantially opposite positions in the direction of the greater length of the belt 30.
- the first cleat 26 and the second cleat 28 are here similar and are for example formed by elements in the form of parallelepiped plates.
- the shape and materials used for the manufacture of the cleats 26, 28 are likely to vary, in particular depending on the type of product Pn to be treated.
- the cleats have a generally "V", “U” or “L” shape in a generally horizontal cross-section arranged on the belt 30 with a predetermined inclination downstream so as product in the direction of the second file F2.
- the belt 30 is wound on a first pulley 34, which is upstream, and on a second pulley 36, which is downstream, and which can be rotated respectively about a first axis of rotation A1 and a second axis of rotation A2.
- the phaser 22 has a main axis X which is parallel to the lower strand 38 of the belt 30 and that it is orthogonal to the axes A1 and A2 of the pulleys 34 and 36.
- the main axis X is inclined downstream so as to form an angle ⁇ determined with the long longitudinal disruption of scrolling products Pn on the conveyor belt 12.
- the value of the angle ⁇ is between 0 ° and 90 °, preferably equal to 30 °, 45 ° or 60 °.
- the lower strand 38 of the belt 30 extends substantially parallel to the upper face 24 of the belt 1 2 at a height which is determined according to the tabs 26, 28 and Pn products.
- the products Pn that are deflected by the phaser 22 are not stopped or slowed down during the distribution operation, which makes it possible to maintain a running speed V1 for each product Pn, deviated or not, and so to obtain ir a high rate distribution according to the desired allocation sequence between the first file F1 and the second file F2.
- the tabs 26 and 28 are positioned on the belt 30 so as to present each vertically when they are on the lower run 38 a lateral deflection face 42 which extends parallel to the long scrolling direction. Pn products on the conveyor belt 12.

- the cleats 26, 28 have a orientation of the lateral face 42 differs from the longitudinal orientation.
- the lateral deflection face 42 of the cleats 26, 28 is intended to come laterally in contact with the product Pn to deflect to exert on the latter a thrust force, d it deflection, preferably substantially in the transverse direction.
- the cleats 26, 28 of the phaser 22 are selectively controlled between at least a first engaged position and a second engaged position.
- the phaser 22 respectively comprises an active operating state in which the belt 30 drives the cleats 26, 28 and a passive operating state in which the belt 30 and the cleats 26, 28 are no longer driven.
- the belt 30 is selectively controlled in its active state or in its passive state as a function of the signals emitted by detection means 44, such as a sensor and / or an encoder, which are arranged upstream of the phaser 22 and that they are capable of detecting the arrival of a product Pn on the belt 12.
- the sensor 44 is, for example, constituted by an electric cell which is arranged at the edge of the belt 12 and that it is electrically connected to the servomotor 40, so that the detection of a product triggers, according to the sequence of d determined allocation, the start of the servomotor 40 at the appropriate time.
- the phaser 22 being controlled selectively according to the detection signal, it is therefore likely to process a queue comprising products whose upstream spacing E1 is not necessarily constant or regular.
- This feature is particularly useful to allow reliable operation of the arrangement 10 according to the invention at high speed.
- the products Pn run on the upper surface 24 of the belt 12 at the running speed V1 and are aligned longitudinally in a first line F1 of the products Pn, with an upstream spacing E1 determined between two products. Successive Pn arranged one behind the other.
- the sensor 44 detects the arrival of a first product P1 and consequently emits a corresponding detection signal, led it signal causing the start of the servomotor 40 so that the belt 30 of the phaser 22 passes from its passive state to its active state.
- the change of state of the belt 30 causes the drive of the first cleat 26 which passes from its retracted waiting position to its first engaged position, as shown in Figure 2.
- the start-up of the servomotor 40 comprises a preliminary acceleration phase ph 1, which allows the belt to move from a zero speed to the deflection speed V2.
- the retracted waiting position is chosen so that the first cleat 26 reaches an intermediate engagement position at the end of the acceleration phase ph 1, before it has reached its first engaged position.
- FIG. 1A the retracted retracted position of the first cleat 26 has been represented in solid lines, the intermediate position of engagement in fine broken lines and the first position engaged in strong broken lines.
- the first product P1 simultaneously occupies its initial position A so as to be deflected transversely by the first cleat 26 out of the first longitudinal line F1.
- the first product P1 deflected by the cleat 26 maintains a constant speed of movement and a relative position on the belt 12 which is identical with respect to the other Pn products.
- the second product P2 located upstream is detected by the sensor 44 but continues, in accordance with the distribution sequence, its displacement longitudinally along the first file F1 without being deflected.
- the distance traveled by the first deviated product P1 determines the transverse distance or spacing "e" between the first file F1 and the second file F2.
- the first product P1 reaches its final position B when the first stop 26 reaches its second engaged position reciprocally.
- the belt 30 temporarily stops being driven and goes into the passive state so as to allow the deflected product P1 to continue its displacement longitudinally along the second file F2, parallel to the first file F1.
- the final position B of each deflected product Pn may be modified for each application and are determined according to the main parameters of the phaser 22, in particular the length of the belt 30 corresponding generally to the center distance A1 -A2 and the position of the cleats 26, 28.
- the belt 30 is then again controlled in its active state and driven by the servomotor 40 to move the first cleat 26 from its second engaged position to the other retracted position, said return.
- the belt 30 is again controlled in its active state and driven by the servomotor 40 to move the first cleat 26 from its second position. engaged directly to the retracted position waiting or the first engaged position.
- the phaser 22 is then ready to deflect the next product Pn from the first line F1 according to the determined distribution sequence, here the third product P3.
- a detection signal is again transmitted to control the rotational drive of the servomotor 40.
- the belt 30 is driven by the servomotor 40 which is controlled by the sensor 44, the second cleat 28 is thus moves synchronously to reach its first engaged position when the third product P3 reaches the initial position A.
- the first and second lines F1 and F2 are out of phase with each other and have a longitudinal spacing E between two successive products respectively belonging to each of the rows F1, F2, which is here equal to the upstream spacing E1.
- FIG. 7 shows a second embodiment of the phaser, the improved phasor 23 being particularly capable of being implemented in an arrangement
- the first 50 and the second 52 belts are arranged side by side substantially symmetrically with respect to a vertical plane having the main axis X of the phaser 23.
- the axis X of the phasor 23 is inclined at an angle ⁇ relative to the long longitudinal direction of the belt 1 2 so that the phaser 23 is positioned oblique downstream with respect to the first file F 1 of products Pn.
- the first cleat 60 of the second belt 52 occupies a retracted retracted position offset by a few degrees of rotation angle of the upstream pulley 34, relative to the retracted retracted position of the first cleat 60 of the first belt 50.
- the two other tabs of the second belt 52 are offset relative to the corresponding tabs of the first belt 50.
- the phaser 23 then operates in a similar manner to a phasing device comprising two phasors similar to the phasor 22 previously described operating independently of one another as a function of the detection of the products to activate the phaser 22. one and / or the other of the servomotors 56, 58.
- phaser 23 The operating principle of the second embodiment of the phaser 23 will be described below, which is similar to that of the phaser 22, but which advantageously makes it possible to process a product stream Pn at a higher, faster rate.
- the presence of a second belt 52 makes it possible to begin to divert another product Pn before the first product P1 has been released in the final position B by one of the tabs of the first belt 50.
- the phaser 23 is shown in the passive state, the cleats 60 occupying the retracted retracted positions previously described.
- the detection signal emitted by the sensor 44 causes the passage of the first belt 50 of the phaser 23 from its passive state to its active state.
- the first servomotor 56 is turned on so that the first latch 60 of the first belt 50 moves from its retracted retracted position to its first engaged position in which it contacts and deflects the product P1 to deviate. his move until reaching his second engaged position.
- the sensor 44 Shortly before the retraction of the first cleat 60 of the first belt 50, the sensor 44 detects the arrival of a third product P3 which triggers the start of the second servomotor 58, the second belt 52 passing from the passive state in the active state.
- the first cleat 60 of the second belt 52 then occupies a first position engaged simultaneously with the arrival of the third product in its initial position A so as to transversely deflect said third product P3.
- the phaser 23 therefore forms a second line F2 which, parallel to the first line F1, consists of the products Pn deflected by the cleats of one or the other 52 of the belts according to the said disengagement sequence.
- the first product P1 having reached its final position B, the first cleat 60 of the first belt 50 then retracts and comes to occupy its retracted retracted position, as the third associated cleat is read to occupy its retracted position d Waiting, if the first servomotor 56 is stopped.
- the first belt 50 of the phaser 23 is again ready to deflect one of the products. its further components that will have been detected by the sensor 44.

- the mounting of the phaser 23 on a gantry 72 makes it easy to arrange it over any conveyor belt 12, and makes it possible to easily choose the longitudinal position and the angle ⁇ of inclination towards the downstream to settle them.
- the gantry 72 comprises, on either side of the belt 12, two vertical longitudinal plates 74, 76 which respectively support the pulleys 34, 36, 54 associated with the first belt 50 and the pulleys 34, 36, 54 associated with the second belt. belt 52.
- the phaser 23 comprises means 78 for adjusting the center distance A1 -A2 between the upstream pulley 34 and the downstream pulley 36 of each belt 50, 52.

- the first product P1 and the second product P2 forming the first intermediate batch L '1 join the cleat 226 of the phaser 222 and abut against the upstream transverse face. of this one.
- the difference in speed between the running speed V1 and the retarding speed V4 of the cleats 226, 228 therefore causes the products P1, P2 to slide on the belt.
- the first product P1 and the second product P2 are then progressively joined by the products P3 and P4 of the intermediary batch L'i following, respectively belonging to the second and first rows F2, F1 and i, downstream of the phaser 1 22. and upstream of the phaser 222, are initially separated by a spacing E 'that i is equal to the upstream spacing E2 between the products Pn + 1 of the first file F1. Indeed, the spacing E 'between the products P1 and P2 of the batch
- a final batch L1 comprising here four products P1, P2, P3 and P4 which are grouped two by two in rows and columns.
- the downstream spacing E "between two batches Li is substantially equal to twice the value of the spacing E 'between the intermediate batches L'.
- the conditioning installation 90 successively comprises first phasing means 122 and second phasing means 222 when the difference between the running speed V1 of the belt and the slowing speeds of the phasing means required to form the batches.
- the i or Li is important, for example when the scrolling speed V1 is twice the required slowdown speed.
- the conditioning installation 90 comprises only first phasing means 1 22 whose characteristics, such as the length of the belt, the position of the cleats or the retarding speed V 2, are determined in such a way that grouping together rank of the first and second products P1, P2 and the grouping of the following products P3 and P4 operate under the lower strand of the phaser 122.
- the conditioning installation 90 comprises, downstream of the exit zone 120 of the conveyor belt 1 1 2, a regrouper
- the first batch L1 is filled with one of the cavities 146 empty, then the train 144 moves from one cell to receive the next batch L2 so that the batches Li of products are for example conveyed by the aggregator 25 to a mach boxing.
- a phasor of the type of phasors 22 or 23 is capable of being implemented to ensure different functions according to the applications.
- the phasor 22 or 23 has the function, in the arrangement according to the invention of the first section T1 of the installation 90, of diverting at least part of the products from one line to form another parallel line, then speaks of a function in two rows, while it provides another function in sections T2 or T3 of the installation.
- the phaser 22 or 23 then has the function of selectively slowing down at least one determined product to align the products transversely in rows and / or longitudinally in columns so as, in the example of the packaging installation 90, to constitute batches of products to be collected by a consolidator to be cashed.
- phaser for the constitution of batches of products is only one possible example of application.
- phaser is still likely to be implemented in an installation type installation 90 to proceed to the balancing of at least one product line of which two products are separated by a determined spacing.
- balancing of a product line means the use of the phaser to slow down at least one given product so that the spacing between two successive products of this queue is in particular greater than or equal to a minimum value. deposit.
- such a minimum value of spacing set point between two products arranged one behind the other or one beside the other corresponds for example advantageously to the time necessary for at least one of the cells of the regrouper is moved one notch and a new empty cell is presented facing the carpet.
- the 25-cell cluster is only one possible and non-limiting example of a product grouping device that can be implemented in an installation, such as the packaging installation 90.
- the grouping device is constituted by a robot or robotic arm provided at its free end with gripping means such as pliers or suction cups so as to collect the products grouped or distributed according to a determined sequence, for example in batches.
- the products are taken dynamically by such a robot, it is de ire without stopping or slowing down the conveyor belt, and the sampling is realisé in the exit zone of the carpet.
- the second section T2 of the belt 1 1 2 consists of two parallel mats between them, respectively a first and a second carpet which are longitudinally aligned with each of the queues. F 1 and F 2.
- the products P of the queue F which are not deflected by the phaser 96 continue their displacement from upstream to downstream and these products Pn + 1 forming the first line F1 are conveyed by the first mat that is trained. at a running speed V1 identical to that of the belt 1 1 2 sections T1 and T3.
- the choice of an appropriate value of the speed of travel V'1 of this second belt with respect to the speed makes it possible to vary the value of the spacing E, that is to say on the spacing between a product Pn of the second file F2 and a product Pn + 1 of the first file F 1.
