Definitions

  • the present invention relates to the field of continuously unroll strip material, in particular reels of PVC or labels or other relatively inflexible materials, for feed continuously, printing, shaping or other machines, and relates to an end-to-end connection device for such a continuous unrolling machine.
  • the end-to-end connection between strips of finishing material and new, especially in relatively inflexible material is generally carried out by using two glued adhesive tapes simultaneously on either side of the joint between the strips on the ends butted. This connection must be able to withstand the traction exerted on the tape during unwinding, as well as during subsequent operations shaping or other.
  • the object of the present invention is to overcome these drawbacks by providing an end-to-end connection device for a unroll continuously allowing an end-to-end connection between two strips, finishing and new, guaranteeing a perfect junction between said strips and avoiding any risk of incident during connection.
  • the end-to-end connection device for a continuous unrolling machine comprising at least one means of unwinding of two reels, a tape accumulator and a device for connection and cutting, is characterized in that it is essentially consisting of a cutting station and end-to-end connection of the strips comprising two opposite pivoting assemblies for preparation, cutting and for connecting the finishing and new bands, each provided with a means for guiding and temporarily holding said strips.
  • Figure 1 of the accompanying drawings shows a machine continuous unwinding allowing continuous unwinding with connection end to end between two finishing strips 1 and new 2 and comprising at less means 3 for unwinding two reels, a tape accumulator 4 and a connection and cutting device.
  • the device for connecting and cutting is essentially constituted by a station 5 for cutting and end-to-end connection of strips 1 and 2 comprising two sets pivoting opposites 6 for preparing, cutting and connecting the strips graduating 1 and new 2 each provided with a means 7 for guiding and provisional maintenance of said bands.
  • the unrolling machine according to the invention is essentially intended for unwinding relatively coils of material rigid such as PVC, or forming a label support, in order to obtain a perfectly reliable end-to-end connection, i.e. guaranteeing resistance to separation by tearing of the strip at the level of the joining via adhesive strips.
  • the two sets pivoting opposites 6 for preparing, cutting and connecting the strips graduating 1 and new 2 each provided with a means 7 for guiding and provisional retention of said bands are complementary and consist each in a pivoting frame mounted on a support shaft of the frame 8 of the machine and comprising, at their end opposite to said support shaft, the means 7 for temporarily guiding and holding the bands, a box 9, capable of sliding parallel to said means 7 for guiding and holding provisional and in the direction of travel of the bands 1 and 2, being guided in said pivoting frame 6 and carrying, on the one hand, a 10 or 10 'part of a device cutting and, on the other hand, a means 11 for receiving and applying a band-Aid.
  • Each pivoting frame constituting one of the opposite assemblies swivels 6 for preparing, cutting and connecting the strips graduating 1 and new 2 is advantageously connected to a means of pivoting actuated by a jack (not shown) and is provided, on the one hand, an actuator 12 for moving the box 9 parallel to the means 7 for guidance and provisional maintenance, in the form of a jack or the like and, on the other hand, means 13 for sliding guide of the box 9, such as rails or bars ( Figure 3).
  • each pivoting frame 6 is provided with a device 14 pinching the start of a new strip 2, this device 14 is advantageously having the form of a movable cross member mounted on one of the faces of said pivoting frame adjacent to that forming the means 7 guidance and provisional maintenance.
  • This movable cross member is guided in displacement relative to the corresponding face by means of guides (not shown) mounted laterally and perpendicular to this said face and is actuated by pinching movement against the face by via a jack not shown, the return to the spacing position of said face being provided by return springs (not shown) mounted on said guides.
  • the new band 2 can be perfectly maintained on the pivoting frame 6 for subsequent cutting and end to end connection with the finishing strip 1.
  • the cutting device consists of two parts 10 and 10 ' consisting respectively of a knife 10 and a counter knife 10 ' mounted, one in one of the boxes 9 and the other in the other box 9 of perfectly symmetrical ( Figure 2). Knife 10 and counter knife 10 'are each actuated in a direction of approximation mutual, by means of a jack, not shown, mounted on the box corresponding and are charged, in addition, each by a reminder member 15 in the rest position, for example in the form of a loaded extraction rod by a return spring.
  • the means 11 for receiving and applying an adhesive strip is advantageously in the form of a guide strip in sliding in the box 9, transversely to the direction of travel of the bands 1 and 2 and provided with an external face provided with suction channels 16 connected to a chamber 19, which is itself in communication with a suction line 20 tightly guided in one of the ends of the strip, on the side opposite to that of the extraction of the casing 9 and connected to a central suction means not shown.
  • This last way can be in the form of a vacuum pump connected to line 20 by through a hose.
  • the suction line 20 is provided with a stop ring preventing any total extraction of said pipe 20 from chamber 19.
  • the strip 20 can therefore be extracted from one side of the box 9 with a view to placing an adhesive strip 21 on its external face, while avoiding untimely disassembly of said strip.
  • this embodiment allows immediate maintenance of the adhesive strip 21 due to the depression created on the external face of the strip, this in the position of the strip outside the box 9.
  • the means 11 formed by the strips are movable towards the bands 1 and 2, in operating position of the pivoting frames 6, each via a cylinder 22 and are returned to the rest position (shown in Figure 2) by via a member 23 for resting in the rest position, for example in the form of an extraction rod loaded by a return spring.
  • Each means 7 for guiding and temporarily holding the bands 1 and 2 consists of a rigid plate comprising at least one opening 7 'for passage of parts 10, 10' of the cutting device or means 11 and of section slightly greater than that of these said devices and average.
  • the parts 10, 10 ′ of the cutting device and the means 11 for receiving and applying an adhesive strip 21 can, when they are moved in front of the openings 7 'of the means 7, cooperate respectively for cutting strips 1 and 2 and for the end-to-end connection of these bands.
  • the plates forming the means 7 are advantageously provided on either side with openings 7 'and over the entire width of guiding the connected strips 1 and 2 of suction grooves (not shown) with two suction chambers, not shown, each chamber being itself individually connected to a central suction means.
  • suction grooves allow effective plating of bands 1 and 2 against the means 7 and maintaining cut parts said bands after cutting. It will then suffice, after removing the depression in the chamber concerned, namely that relating to the end of the new strip and that relating to the part of the ending strip from the spool, remove the ends of the finishing strip 1 and new 2 concerned of the means 7 to have more than two ends of butted strips to be connected.
  • a consecutive displacement of the boxes 9 bringing the means 11 with the adhesive strips 21 in front of the openings 7 ′ will then allow the initiation of the actual connection operation which is performed by actuating the corresponding cylinders 22. It follows that the adhesive strips 21 are tightened, on either side of the joint, on the ends of the bands 1 and 2. At the end of the actuation of the jacks 22, the means 11 are automatically returned to their starting position and the new strip 2 can be driven to a machine downstream.
  • the unused strip parts i.e. the end of the new strip 2 tightened in the clamping device 14, as well as the end of finishing tape 1 of the finishing reel can be removed respectively manually by pulling on this end of the strip after suppression of the corresponding depression in means 7 and after opening of the clamping device 14 and by actuation of the coil ending in the direction of a winding of the latter.
  • Suction means for holding the adhesive tapes 21 as well as strips 1 and 2 against the internal faces of the means 7 are of known types and do not require a more detailed description.
  • the suction grooves can be arranged in groups symmetrical with respect to the longitudinal axis of bands 1 and 2 and be connected to negative pressure chambers controlled in pairs. So known, each negative pressure chamber can be connected to a central suction means via control valves manual. Such an arrangement is also known to those skilled in the art nor does it require a more detailed description.
  • the two opposite pivoting assemblies 6 for preparation, cutting and connecting the finishing strips 1 and new 2, fitted each of a means 7 for guiding and temporarily holding said strips, are preferably arranged in a closed frame 8 and provided with a part front closed by sliding or hinged doors, not shown in detail, the upper part of the machine, above the sets 6 being fitted with hinged covers 23.
  • Front doors provide access, particularly to reels to unwind and to the tape accumulator 4, while the covers folding 23 allow, after opening, pivoting of the assemblies 6 in a prepared position for a new strip 2, like shown in Figure 1 of the accompanying drawings.
  • the preferred embodiment shown in Figure 1 provides a constitution in which the unrolling machine is presented like a relatively low machine in which the coils are arranged in the same horizontal level and the cut and the connection take place in a vertical position of the bands.
  • the cutting of the strips is carried out in a horizontal position and the coils are arranged vertically one above the other with interposition of the cutting device and connection.
  • connection obtained is particularly reliable.
