Definitions

  • the invention relates to a method and an installation for combine aligned items in batches using strip sections adhesive with flaps.
  • the items are arranged in a continuous line on a upstream conveyor bringing them to means spacing two, three or four items from the rest of the queue to form a batch, then this batch is brought, by a downstream conveyor, to an item gathering station, where means apply two sections of adhesive tape to them. Each section extends between a front end, folded against the front part of the first item of the batch, and a rear end, folded against the part back of the last item in this batch.
  • the object of the present invention is to provide a method and a installation making it possible to remedy these drawbacks.
  • this process also consists, after the batching phase, by stopping the upstream conveyor, to move each of the belt return rollers adhesive, from a return position, in which it returns this strip on a tangent path to the articles at a plating position in which this roll intersects the normal trajectory of the adhesive strip and clamp it on the front part of the first article of the next batch, in waiting in the upstream conveyor, then, after cutting the strip, at return the roller to its original return position.
  • the return rollers not only ensure the return adhesive tapes giving them a path parallel to that moving the items and pressing them against those items but also, before sectioning, the plating of these strips on the part upstream of the first article following a batch and the pinching of these bands on the article, to improve their retention during sectioning.
  • this process consists of moving the upstream conveyor simultaneously each of the return rolls of the adhesive strips between a position of return, in which this roller returns the adhesive tape on a trajectory parallel to that of the articles, and a recessed position, in which the adhesive strip describes a trajectory which, inclined with respect to that of displacement of the batch, is approaching it from the return roller to the last item in the batch being formed, then, after stopping the batch and before actuating the knives, bring each roller to its initial position for returning the adhesive tape and plating of it on the first article of the following batch.
  • the invention also relates to the installation allowing to ensure this meeting in batch.
  • the deflection rollers and the knives are arranged substantially in the transition zone between the conveyor upstream and downstream conveyor, while, on the one hand, the supply of motor means of the upstream conveyor is dependent, through the control and command assembly, of a sensor cutting this feed to the passage of the first article of a batch in training on the downstream conveyor, and that, on the other hand, each of the rollers is carried by means movable transversely and in both directions, from a return position, in which this roller returns the adhesive tape to a trajectory parallel to that of moving articles.
  • lot A of multiple cylindrical elements 2, such as two cylindrical boxes 2a, 2b, is produced by two sections 3a of adhesive strips 3, the ends of which, respectively, front 4 and rear 5, are folded down on the elements extremes composing lot A.
  • the installation ensuring this batching includes, as shown in Figure 2, an upstream conveyor B, a downstream conveyor C and, in the transition zone between these two conveyors and on either side of the displacement trajectory of the cylindrical articles 2, two sub-assemblies D, cutting adhesive tapes 3.
  • the upstream conveyor feed B is composed of a longitudinal and horizontal conveyor 6, carrying horizontal and transverse rollers 7, mounted free in rotation, and two belt conveyors B1, B2, lateral and vertical.
  • Each of these belt conveyors is composed of a motor roller 8, a deflection roller 9 and one or more endless belts 10, circulating around these rollers, forming a band in the horizontal plane.
  • the strands opposite the bands 10 are parallel and spaced by the value of the diameter of the cylindrical articles to be driven, in the direction of the arrow 11.
  • Each of the motors 8a of the motor rollers 8 is supplied by an electrical circuit 12, under the control of a control and control 13.
  • the downstream conveyor C which can be of the same type as the conveyor B, is shown here as a belt conveyor 14 whose upper strand is horizontal and is an extension of the conveyor 6 with rollers 7.
  • This belt describes an endless trajectory around a drive roller 15 and a deflection roller, not shown.
  • the motor roller 15 is driven by a motor 16 whose power is provided by a circuit 17 going to the control unit 13.
  • Each of the subsets D comprises a reel 20, motorized or not, for a reel 22 of adhesive tape 3, a roller vertical return and plating 23 and a knife 24.
  • Figures 2 and 3 show that the rollers 23 and the knives 24 are arranged downstream of the upstream conveyor B and in the area of transition between this conveyor B and the downstream conveyor C.
  • Each deflection roller 23 is supported by suitable means to move them transversely and in both directions between, a position return, shown in Figure 2, in which it allows the strip 3 to tangent the articles 2 in scrolling, and a position of plating, shown Figures 3, 5 and 6, and in which this roller partially intersects the trajectory of the containers and comes to bear on the article 2c exceeding upstream conveyors B.
  • each of the rollers 23 is mounted free to rotate about a vertical axis in a yoke 25 formed at the free end of the rod 26 of a pneumatic cylinder 27.
  • This cylinder is fixed to an element 28 of the installation frame and is powered by a pneumatic circuit through a solenoid valve 29 piloted by the control unit 13.
  • a support 30, carrying the knife 24, is also wedged at the end of the rod 32 of a pneumatic cylinder 33, fixed on element 28 of the frame.
  • This pneumatic cylinder 33 is supplied by a circuit pneumatic by means of a solenoid valve 34 which, independent of that 29, is connected by an electrical circuit to the control assembly 13.
  • the support 30 carries two brushes 35 laterally, the utility of which will be explained later.
  • this installation comprises two sensors, respectively upstream 37 and downstream 38, each connected by a suitable circuit to the housing command 13. These sensors are fixed in an adjustable manner on a support, not shown, and are intended to detect the passage of the first element 2a of a batch being formed to trigger functions that will now be described.
  • Belt conveyors B1 and B2 move items 2 by file continues in the direction of arrow 11 and therefore tend to chase the first article 2a on the downstream conveyor C.
  • This article 2a being linked by adhesion to the ends 4 of the adhesive tapes 3, folded over it when carrying out the previous batch, moving it in the direction of the arrow 11, Figure 2, carries with it the adhesive strips 3.
  • the rollers 23 these strips are affixed to the various elements making up the batch and, by example, on articles 2a and 2b.
  • This interval E is adjustable and determined by the longitudinal position of the downstream sensor 38, since the latter cuts the supply of the motor 16 for driving the downstream conveyor C, when passes before him the first article 2a of lot A, as shown in Figure 4.
  • the sensor 38 also triggers, by the solenoid valve 29, the supply of the jacks 27 in the direction of their extension to move transversely the return rollers 23 from their return position to their plating position.
  • rollers 23 come, as shown in FIG. 5, press and pinch the adhesive strips 3 on the front part of article 2c protruding from conveyors B1 and B2.
  • each knife cuts the strip 3 in its part 3b which is perfectly positioned by adhesion on articles 2b and 2c.
  • the brushes 35 carried by the support 30 of each knife, fold and flatten backwards the cut ends 4 of the strips 3, against the front face of article 2c, and, towards the front, the posterior ends 5 of the sections of strips 3a, linking the elements of lot A, against the rear part of the article rear 2b of this lot ( Figure 6).
  • all of control and command 13 controls the return of rollers 23 and knives 24 at their initial positions, respectively, returning and wait, and a new cycle begins again.
  • the method and the installation according to the invention ensure this separation only after the elements of the lot have already been brought together them by the adhesive tapes, which provide many advantages.
  • This lack of space between articles improves the rigidity of the batches obtained, guarantees the longitudinal positioning of the bands and, consequently, the repeatability size and aesthetic appearance of the lots.
  • cutting strips by means of a knife acting on a section held by these two ends the installation makes it possible to obtain sharp, clean cuts and perfectly positioned.
  • the same installation can also ensure the batching of articles rectangular 102a, 102b, 102c, ..., with some adaptations of its control assembly 13 and sub-phases of its method of based.
  • batching articles 102a, 102b are also made by stopping the only upstream conveyor B, and movement of the articles under the control of sensors 37 and 38, but the rollers 23 are moved differently.
  • the upstream sensor 37 at the same time as it controls the stopping of the upstream conveyor B, through the control and command assembly 13, also controls actuation of the solenoid valves 29, in the direction of retraction of the cylinders 27, in order to bring the return rollers 23 from their normal position of return to a withdrawal position.
  • the adhesive strips 3 which are pulled by the articles of lot A ', and possibly assisted by motorized reels 20, describe a 3d inclined trajectory which is approaching the normal trajectory, so from the sides of the articles, going from the roll 23 to the side of the last article 102 b of lot A '.
  • the strips are far apart transversely of the sides of the following article 102c and are not likely to sticking to these sides during the spacing of the articles forming the lot A '.
  • the solenoid valves 29 in addition to stopping the downstream conveyor C and the reels 20, first, the solenoid valves 29, then the solenoid valves 34, in the direction of the extension of the jacks 27 and 33.
  • the rollers 23 return to their original return position and press the adhesive strips 3 onto the sides of article 102c pending (Fig. 8), before the operation of sectioning by the knives 24 and the folding operation by the brushes 25.
