Definitions

  • the invention relates to a method and a device for bringing together lots of packages, articles or equivalent items, substantially parallelepipedic, by means of longitudinal sections of bands adhesives.
  • the products are moved in line on an upstream conveyor then are formed in a batch of n packages at a separation station, before being brought, by a downstream conveyor, to a deposition station or two adhesive tapes are applied to each of the longitudinal sides of the lot, going from the most downstream package to the most upstream package of the lot.
  • each adhesive strip unwinding from a reel is applied by an applicator roller on one of the two opposite sides of the batch and is drawn by it, as it progresses.
  • each side adhesive strip is thus applied over the entire length of the batch, it extends in the interval with the next batch.
  • conveyors are stopped and knives cut the two strips in the interval between two batches.
  • the sectioned ends of the strip sections linked to the lot are then folded against the rear transverse edge of the lot, while the ends bands still linked to the coils are folded against the ends before the first item in the next batch.
  • the bands are applied to packages or boxes that are often poorly maintained and occupy a non-rigorous position, so that the vertical position of these bands on the packets may vary and that there may be between packets of a lot, more or less important intervals causing a lack of rigidity of the batch and consuming more strip length.
  • the installation of the strips is not reliable and prevents use pre-printed adhesive tapes.
  • each batch necessarily has, on its faces upstream and downstream, the drawdowns of the severed ends of the strips adhesives. These drawdowns, which may have lengths different from one lot to lot, negatively affect the presentation of lots for sale.
  • Another method consists in cutting each section of adhesive tapes, prior to being deposited on the elements of a batch. This technique makes it possible to imitate the length of the sections to the length of a batch, therefore not to form transverse flaps, but sets uses complex mechanical means to, respectively, maintain each strip section and place it on the stationary batch.
  • this one puts in work of the means which are inserted in the trajectory of displacement of batches and which may, in the event of incorrect settings, deteriorate the elements of the lots.
  • the adhesive tapes deposited on the packets in continuous file are provided with lines of pre-cut spaced apart the width of a bundle and the separation of the first batch of the rest of the queue is made, according to the first document, by pressing of rotating electrodes applying on the plane of separation between two bundles, and according to the second document by transverse shearing, that is with the help of an inclined plane, either by rotating cams moving vertically the last pack of the first batch to favor the breaking of pre-cut lines passing through the separation plane between the first batch and the first package of the next batch.
  • the object of the present invention is to provide a method providing a reliable positioning of the strip sections, allowing to use pre-printed tapes, while eliminating all risks of deterioration of batch components.
  • This process is one of those comprising a deposition phase adhesive strips on the elements in line and a separation phase elements forming a first batch of the first element of the following batch, this phase being carried out by extension and tearing of lines of pre-cut previously made in the adhesive strips and positioned in the transition zone between two lots.
  • the invention consists, in each adhesive strip, of space the precut lines by the length value of a batch and in the separation phase of the first batch, to tear the lines of pre-cuts between the first batch and the following batch by communicating to the whole of the first batch a longitudinal translational movement of speed V2 higher than the speed V1 communicated to the elements in line ensuring the rupture of the strips by a longitudinal tensile force.
  • the invention also relates to the device for setting work of this process.
  • the means ensuring the rupture of the precut adhesive strips, by longitudinal traction and the batching, by separation of the first batch from the following batch are constituted by a batch conveyor arranged downstream of the rollers application of pre-cut adhesive strips, and suitable for driving the first batch with a speed V2 higher than that V1 of training by the upstream conveyor, elements in line.
  • the downstream conveyor is provided with motor means capable of driving it permanently at a speed V2 greater than that V1 of the upstream conveyor and its upstream end is longitudinally spaced from the rollers applying the adhesive tapes against the elements of the first batch of a distance S of value at least equal to that of the length of a batch, therefore of the interval between two lines pre-cut adhesive strips.
  • the downstream conveyor is juxtaposed with the application rolls of the adhesive strips and comprises, on the one hand, motor means) with adjustable speed which, capable of driving it cyclically either at the same speed (V1) as the upstream conveyor, or at a speed (V2) of value greater than that of (V1), and on the other hand, means detecting the feeding of the precut lines in the area of transition between two batches and triggering the temporary acceleration of the speed of this downstream conveyor.
  • the device according to the invention comprises a horizontal conveyor A, composed of rollers 2 mounted free in rotation around a horizontal axis transverse to the direction of movement of the elements on the conveyor, represented by arrow 1, an upstream conveyor B and a downstream conveyor C and, between these two conveyors and on either side of the conveyor longitudinal A, two subsets D.
  • Each sub-assembly D comprises a reel 3 motorized by an electric motor 3a for a coil 4 of adhesive tape 5, various return rollers 6, and an applicator roller 7, returning the strip corresponding adhesive 5 on a path which is parallel to that of the elements to be assembled in batches and tangent to these elements.
  • the conveyors are endless belt conveyors and are each composed of two lateral elements respectively B1, B2 and C1, C2.
  • Each of these elements includes a vertical cylinder and motor 8 and a vertical return cylinder 9, guiding and driving at least an endless belt 10.
  • the interval between the two side elements is adjustable so that the space between the strands in vis-à-vis the strips 10 is at most equal to the transverse dimension of the elements to be trained.
  • the motor rollers 8, respectively of the upstream conveyor B and the downstream conveyor C, are driven by geared motors, respectively 12 and 13, the supply of which is controlled by a set 14 also controlling the power supply to the motors 3a of the reels motorized 3.
  • the downstream conveyor C is longitudinally spaced from the applicator rollers 7 from the adhesive strips 5 by a distance S which is at least equal to the length of a lot L.
  • the Figure 1 shows that this distance is measured between the transverse planes P1, P2 passing through the diameters, respectively, of the rollers 7 and the return cylinders 9 of conveyor C.
  • each of the distribution subsets D of a adhesive strip 5 includes a punch 15 cooperating with an anvil 16.
  • This punch has a toothing allowing it to achieve in the corresponding adhesive strip 5 a precut line 17, one of which embodiment is shown in Figure 7.
  • This punch 15 is worn by means able to move it transversely and, for example, a jack tire 18 at the end of which it is wedged and the supply of which is provided by a solenoid valve 19 controlled by the control assembly 14.
  • Each assembly, cylinder 18 and anvil 16 is fixed in an adjustable manner on a plate 20, so as to allow the position of the line to be adjusted pre-cut 17, so that it takes place on the part of the strip adhesive 5 coming in the transition zone E between two successive lots ( Figure 2).
  • the plate 20 occupies a position fixed, while in the variant shown in Figure 1, it is mounted sliding on slides 22, parallel to the section of the trajectory of band 5 passing in front of the punch 15.
  • This plate is then connected to means capable of moving it on these slides, such as a pneumatic cylinder 23.
  • the supply of this jack 23 is provided by a solenoid valve 24 controlled by the control assembly 14.
  • the plate is follower, that is, in a forward phase, it moves at the same time and at the same linear speed as band 5, so as to allow carrying out the precut 17, and that, in a return phase and after realization of this precut, it moves in the opposite direction, but with a higher speed, to return to its starting point.
  • the device also includes two sensors respectively downstream 25 and upstream 29 electrically connected to the control unit 14.
  • the downstream sensor 25 detects the passage of the first element 32a of a batch L. It is adjustable in position to adapt to the variation in length of the batches. In the embodiment shown, it is fixed in an adjustable manner on a support 26, itself fixed on one of the two chassis 27 carrying the elements C1, C2 of the downstream conveyor.
  • Each chassis 27 is mounted sliding on longitudinal slides 28, parallel to the conveyor A, so as to be adjusted in position to adjust the value of the dimension S in depending on the length of a lot L. It is obvious that each of the frames 27 is blocked on the slide 28 by suitable locking means although known to those skilled in the art.
  • the upstream sensor 29 is fixed to the frame upstream of the rollers tackers 7. It is intended to detect the presence of elements 32 in the queue elements from the upstream conveyor B.
  • each sub-assembly D for distributing the adhesive tape 5 is provided of a pre-cut punch 15 at a stationary position, it will now be described, with reference to Figures 2 to 5, the conditions of batching, boxes or parallelepipedic packages 32, to be combined in lots E of three units.
  • the articles 32, placed on the longitudinal conveyor A are moved in continuous file and at speed V1 by the two elements B1 and B2 of the upstream conveyor B.
  • the upstream sensor 29 controls, by the housing 14, the power supply to the motors 3a causing the unwinding of the bands 5.
  • the element 32a reaches between the two rollers applicators 7 and receives on its two lateral sides the ends of the adhesive tapes 5, the tape pulling effort is practically zero, since compensated by the displacement of these bands.
  • the sensor 29 reacts on the housing control 14 to trigger the shutdown of the motors 3a. So the lot incomplete remains on conveyor A, in zone S waiting to be completed by a new element 32 brought by the upstream conveyor B which continues to operate.
  • the first element 32a When, as shown in FIG. 3, the first element 32a is detected by the downstream sensor 25, it acts on the control unit 14 which stops the supply of electric motors 12 ensuring the drive of the two lateral elements B1, B2 of the upstream conveyor B. This stop, timed and simultaneous with the stop of the motors 3a of the reels 3 is used to supply the jacks 18 causing the formation, by the punches 15, pre-cut lines 17 in the adhesive strips 5.
  • the motors 12 of the two elements B1, B2 of the upstream conveyor B and the reels 3 are again fed.
  • the line of elements 32 moved by the conveyor B continues to push the elements 32a, 32b, 32c of the first batch L1 by causing the deposition on their side faces of the adhesive strips 5.
  • This advancement brings the lines of precut 17 in coincidence with the transition zone E (FIG. 5) between two successive batches L1, L2 and brings the front end of batch L1 into the downstream conveyor C.
  • the first element 32a When, as shown in Figure 5, the first element 32a is engaged between the strips 10 of elements C1, C2 of the downstream conveyor C, it is driven by these bands at a speed V2 higher than the speed V1 of the upstream conveyor B.
  • the three elements of the batch L1 are thus moved faster than elements 32d, 32e of the batch along L2 exiting conveyor B.
  • This speed difference exerts on lot L1 and on the adhesive strips 5 a longitudinal tensile force favoring the rupture by tearing of the precut lines 17 and the separation of batch L1 of the first element 32d from batch L2 during training.
  • the device according to the invention allows you to combine any number of items into a batch parallelepipedic by joining them by two lateral bands, extending only along the length of the longitudinal sides of the lot and not including no flaps.
  • This device does not use any means secanting the movement trajectory of the elements of the batch and the batches, which removes any risk of deterioration of these elements or lots, if only in the device adjustment phases.
  • FIG. 6 shows that at least one of the subsets D can be equipped, in addition to the means carrying out the precut, with means for depositing on the adhesive face of one of the adhesive strips 5 a label 40.
  • These means include a magazine 42 containing labels 40 and a piston 43 actuated by a pneumatic cylinder 44 and suitable to press the strip 5 against the first label of the magazine, during the interruption of the scrolling of this strip 5.
  • each punch 15 can be operated several times or be combined with other punches to make, in each section of strips 5, not only pre-cuts 17, favoring the sectioning into sections of the strips 5, but also, as shown in FIG. 8, i.e. precut lines 17a in the intervals between elements of a batch, to facilitate gripping of each elements in the batch, i.e. precut lines 17b, arranged on one side or on both sides of a label 40, to facilitate gripping of this label.
  • the label may consist of a bonus sticker providing either points in a game or a handing over at checkout.
  • the two elements C1, C2 of the downstream conveyor C are juxtaposed to the rollers 7 for applying pre-cut adhesive strips 5, and therefore immediately following the upstream conveyor B, and on the other hand, are each provided with an electric motor 13 with adjustable speed.
  • the supply of these motors is dependent on sensors, not represented, reacting to the passage of at least one precut line 17 in the transition zone E between two lots. So as soon as the stretches of bands 5 are applied to the elements forming a batch L1, bands 10 of the downstream conveyor C which until then had been moved at a speed equal to that V1 of the upstream conveyor, are moved at a higher speed V2.
  • the difference of speed provides a longitudinal tensile force causing the rupture of pre-cut lines 17 and the separation of the batch from the other elements in file.
  • the downstream conveyor C After this separation, the downstream conveyor C returns to its speed normal V1 to accommodate the first element of the next batch, then starts a new temporary acceleration cycle.
  • the device described is intended for installing lateral strips, but it is obvious that, by means of a modification of the position around of the trajectory of the elements 32, respectively, of the conveyors and the two sub-assemblies D for unwinding, pre-cutting and plating the adhesive strips 5, these can be applied to the faces, respectively, upper and lower of a batch.
