  • a piece of tape is applied to a load of bottles or bricks, in width or length, as required.
  • the ends of the section are glued on both sides of the pack, while the intermediate portion serves as a gripping handle. So that the hinge is not sticky, the tape section has in this area either a cardboard label reported or a non-sticky plastic insert directly integrated with the adhesive tape, then called "handle prepared".
  • one or more sections of adhesive tape are applied to a set of unit products to secure them together and form a batch.
  • the length and width of the adhesive tape may vary depending on the type of product to be equipped.
  • it is imperative that the length at which the section is cut is perfectly determined and reproducible, to guarantee the correct positioning of the inscriptions or the plastic insert on the different sections successively prepared.
  • the invention aims to improve devices and methods for preparing sections of adhesive tape.
  • the device according to the invention it is possible to freeze the gripping zone but to position the release zone at the desired location on the forward strand, depending on the length of the desired tape section.
  • This setting does not involve complicated constructive modification.
  • the adhesive tape cutting system allows the maintenance of this tape once cut on the upstream side, it is not necessary to provide a second clamp that would hold the ribbon upstream, and which would be removed from the first clamp a certain distance. On the contrary, even with a single clamp, it is possible to bring this clamp to the gripping area for subsequent traction of another section of tape, while the prepared section is transferred to a position of use.
  • the device comprises a fixed cam arranged facing the forward strand to cause the closure of the clamp in the gripping zone and maintain the clamp in the closed position over the entire length of said fixed cam, and a movable cam extending in extension of the fixed cam opposite the forward strand, at least up to the zone release, said movable cam being movable between an advanced position, in which it holds the clamp in the closed position, and a retracted position, in which it allows the passage of the clamp in the open position.

  • Each chain 2 forms a plane loop comprising a forward strand 3 and a return strand 4 substantially rectilinear and parallel, and two half-circle portions respectively winding around a drive wheel 5 and a free idling wheel 6 of respective axes 7, 8 substantially parallel.
  • the driving wheel 5 is driven by a motor 9, in the direction indicated by the arrow in FIG. 1.
  • the terms "upstream” and "downstream” are defined with respect to the direction of movement of the chain 2.
  • the motor 9 is for example an electric motor of any type (DC, asynchronous, brushless, etc.). Management of the acceleration and deceleration curves, stop accuracy and nominal speeds is performed via frequency converters or axis cards depending on the selected motor technology.

  • This system comprises on the one hand a fixed cam (not represented) arranged next to the forward strand 3 from a so-called gripping zone 31, and secondly a movable cam 32 extending in extension of the fixed cam facing the forward strand 3, at least up to a zone known as the release zone 33
  • the movable cam 32 driven by a pneumatic actuator, can be moved between an advanced position (by default), in which it is located substantially in the same plane as the fixed cam, and a retracted position.
  • the cams are intended to cooperate with the rollers 29 of the gripper 17 during the displacement thereof on the forward strand 3.
  • the device 1 comprises a cutting system 34 for cutting the towed adhesive tape 14 to form a separate section of the coil 13.
  • the cutting system 34 is located near the forward strand 3, on the traction path of the adhesive tape 14, immediately downstream and as close as possible to the gripping zone 31.
  • the cutting system 34 comprises on the one hand a cutting block 35 disposed on the smooth side 26 of the towed adhesive tape 14, and having a transverse knife 36.
  • On either side of the knife 36 are disposed support elements, respectively upstream 37 and downstream 38, to ensure the adhesive tape 14 at the time of cutting, as will be seen later.
  • the downstream support element 38 may be equipped with a flexible material element (for example foam or polyurethane).
  • a pneumatic actuator 39 controls the cutting block 35 to bring it closer to or away from the adhesive tape 14, the cutting block 35 being by default in the retracted position, that is to say away from the adhesive tape 14.
  • the cutting system 34 further comprises a counter-cutting block 40 disposed on the adhesive side 23 of the towed adhesive tape 14, and comprising an upstream front finger 41 and a downstream finger 42, spaced from each other and located opposite the support elements 37, 38 of the cutting block 35.
  • the counter-cutting block 40 serves to hold the adhesive tape 14 in tension at the time of cutting, on either side of the knife 36 , using the sticky power of the adhesive tape 14.
  • the upstream finger 41 is substantially parallelepipedic, while the downstream finger 42 comprises at least one roller 43 rotatably mounted about the main axis of said downstream finger 42, arranged transversely. It can be a knurled brass roller or freewheels.
  • a pneumatic actuator 44 drives the countercut block 40 to bring it closer to or away from the adhesive tape 14, the counter-cutting system 40 being by default in the retracted position, that is to say away from the adhesive tape 14 , position in it releases the space required for the passage of the clamp 17, between the cutting block 35 and the counter-cutting block 40.
  • the detection modes do not work at the same time, one of them being chosen beforehand at the level of the control system.
  • the section of cut tape 14 is held at its end pulled by the clamp 17 located in the release zone 33, and at its other end by the downstream finger 42.
  • the adhesive tape 14 unwinding the coil 13, it is maintained at its upstream end by the upstream finger 41.
  • the upstream finger 41 being parallelepipedic, it allows a bonding of the adhesive tape 14 on a larger surface than a cylindrical finger, and therefore a better hold.
  • the adhesive tape 14 is always held on the reel side pending the arrival of a new clip 17.
  • the device 1 can be placed in any position in space, the gravity not risking moving the adhesive tape.
  • the opening of the clamp 17 is then controlled by moving the movable cam 32 to its retracted position.
  • the adhesive tape 14 remains held at its towed end, by gluing on the first branch 21.
  • the section of adhesive tape 14 thus prepared is then transferred to a use station (not shown) in a direction substantially orthogonal to the plane of the towed adhesive tape. During this movement, the adhesive tape 14 is easily detached from the clamp 17 and the downstream finger 42 by causing the rotation of the roller or rollers 24, 43 towards each other. It should be noted that, on the side of the towed end, the adhesive tape 14 is very well held on the first branch 21 of the clamp 17, because it has been well applied to the roller or rollers 24 by crushing the element The gripper 17 must therefore be open to allow the adhesive tape 14 to detach.
  • the adhesive tape 14 is only slightly stuck on the downstream finger 42 (generally on a generatrix), and it is therefore not necessary to move the counter-cut block 35 to its retracted position to allow the release of the adhesive tape 14.
  • the transfer can for example be performed by a jack system 46, disposed on the smooth side 26 of the adhesive tape 14 (see Figures 5 and 13).
  • the traction of the adhesive tape 14 is independent of the movement of the product or products to be equipped with said ribbon, which makes it possible to perform a better controlled bonding, while the products are stopped.
  • the chains 2 are then moved again, the clamps 17 thus moving simultaneously to bring the clamp 17 which was waiting on the return strand 4 to the gripping zone 31, while the clamp 17 which has just pulled the adhesive tape 14 being discharged on the return strand 4.
  • the stop of the clamp 17 in the gripping zone 31 is controlled by a detection cell.
  • the clamp 17 closes in this movement, in contact with the fixed cam, just before the cutting system 34.
  • the longitudinal distance between the counter-cutting block 40 and the input of the fixed cam is fixed.
  • the adhesive tape 14 coming from the coil 13 is now engaged in the clip 17.
  • the device 1 is then in the initial situation described above, and the traction / cutting cycle / movement of the clamps can be repeated.
  • the average time of a cycle can be of the order of 0.65 seconds.
  • the return of the gripper coming from towing the adhesive tape is operated in masked time, while the other gripper in turn tows the adhesive tape.
  • the forward strand 3 materializes the trajectory of the adhesive tape and the possible lengths of traction. This length can be easily parameterized by freezing the positioning of the gripping zone 31 and by providing a plurality of successive moving cams 32 in extension of the fixed cam. According to the active moving cam, the release zone 33 is thus positioned.
  • the motorized drum 47 materializes a physical cut between the bobbin winding lever 49 (animated oscillations) and the device 1. It ensures the traction of the adhesive tape from the spool 13 and assists in feeding the adhesive tape to the gripper 17 when it was put into action.
  • the motorized drum 47 cash therefore the largest tensile force related to the unwinding of the adhesive tape from the coil 13 (about twice the force measured between the drum and the clamp).
  • the primary traction is provided by the drum, the unwinding is performed at the unwinder (by rotation of the spool 13). Between the device 1 and the drum, the primary traction is provided by the gripper 17, unwinding and secondary traction being provided by the motorized drum 47.
  • the traction of the adhesive tape 14 by the movement of the clamp 17 on the chains 2 causes the muffle 48 to oscillate at the output of the motorized drum 47 and disengages the detection cell.
  • the non-detection of the muffle 48 then triggers the rotation of the motorized drum 47.
  • the pulling of the adhesive tape by the drum then oscillates the unwinding lever 49 and disengages the detection cell.
  • the non-detection of the unwinding lever 49 then triggers the release of the electromagnetic brake of the unwinder, thus allowing the spool 13 to rotate and the adhesive tape 14 to unfold.
  • the traction of the adhesive tape is thus managed by cascading the various actuators. Stopping the unwinding of the coil 13 is obtained not the inverse reaction of each actuator, triggered from the stop of the clamp 17 at the end of the stroke on the forward strand 3, that is to say in the zone of release 33.
