Definitions

  • the invention relates to a film feed unit according to the preamble of claim 1.
  • Such a unit is known from FR-A-2 520 707.
  • the two supply rolls are arranged in mirror image to a double-acting clamping device and each of the supply rolls is assigned an electrical contact on the stretch of the film strip.
  • the respective circuit of these contacts biased against the foil strip is interrupted by the insulating effect of the foil strip and is only closed when the end of the foil strip has been reached. The then closed contact temporarily stops the film strip so that the beginning of the next supply roll can be automatically connected to the end of the expired film strip.
  • This known device enables an automatic tape change after the tape of the one supply roll has completely run off.
  • connection device for a web made of plastic for the manufacture of containers, which can be started essentially by hand control, is known.
  • an adhesive tape is positioned on the new tape start between a pressure rail and a movable knife part.
  • a cylinder receives compressed air, which lowers a clamping stamp and a pressure rail onto the end of the belt.
  • a knife cuts the ribbon. After the connection process, the knife must be removed by hand below the interconnected webs and reinserted above.
  • a device for feeding a paper web or the like is known from GB-A-1 447 860.
  • This known device has a rotatable carrier which is mounted in its center and carries a supply roll at each of its two ends.
  • the paper webs drawn off from the supply rolls are brought together in a connecting unit, which is followed by a compensating device.
  • the compensation device serves as a memory so that the feed to a downstream processing machine, for example a printing press, does not have to be interrupted during the change of the paper web drawn off the rolls.
  • the roll change does not take place automatically, so that an operator has to be present to press a button when changing the roll.
  • the present invention is based on the object of designing a feed unit of the type specified in the preamble of claim 1 in such a way that the removed film strip changes from one supply roll to the other even when the film strip has at least one defect.
  • the roll change prepared by the operator is initiated automatically by responding to the scanning device if this device detects an irregularity in operation, which is either the end of the film strip or a fault location.
  • the film feed unit according to the invention is intended for a tube manufacturing machine which processes, for example, laminate films, it has proven to be expedient to detect defects using the thickness measuring device.
  • the thickness measuring device responds not only to actual irregularities in the thickness of the films, but also to unevenness, such as kinks. Such irregularities would lead to faults or rejects in the downstream tube manufacturing machine, which rolls up the film strip into tube tubes and welds it along the seam.
  • the film feed unit according to the invention thus also takes over a quality control of the supplied film strip.
  • the result is an uninterrupted, largely trouble-free operation of the downstream tube manufacturing machine as well as a perfect quality of the tube tubes manufactured with it. This is particularly important because the processed laminate film has a metallic layer in addition to plastic layers, kinks being particularly annoying for further processing on the one hand and also for optical reasons.
  • the feed unit which automatically carries out the roll change, not only works independently of the operator, but also faster than the operator is able to do by hand, so that a continuous compensating device is used Operation of the supplied packaging machine, especially the tube manufacturing machine, is guaranteed.
  • a locking device having a retractable conical mandrel ensures that the counter-roller that is in each case used is positioned exactly.
  • the respective counter-roller is guided at its free end in a fixed guide by means of a bearing arranged on its shaft end. In addition to the exact positioning, this also results in a particular rigidity in the mounting of the counter roller.
  • a corresponding tension of the film in the scanning device is achieved by a braking action constantly exerted on the supply rolls in order to ensure their safe function. It is important that the counter roll is at least partially wrapped in the film strip so that the spring-loaded measuring roll is not hindered by the strip tension.
  • the scanning device can be used to control a stopping device with a rubber-tipped stopping roller in order to stop so precisely when a fault location is found that the part to be separated from the film strip is kept as short as possible.
  • film strip 16 is drawn off from a first film strip supply roll 12 placed on a first winding mandrel 10 by means of a band feed device 14 and fed in the direction of arrow 18 to a tube production machine (not shown).
  • the film strip 16 is preferably a laminate film strip, which in cross section consists of an inner plastic film, an aluminum film and an outer, already printed plastic film.
  • the tube manufacturing machine the film strip is cut off in a first step, wound into a tube and welded.
  • the tube head is attached to the tube and then a cap is screwed on.
  • the film strip 16 comes into contact with the following devices: scanning device 20, cutting table 22, stop device 24, optical scanning device 26, compensation device 28, trimming device 30 and tape feed device 14.
  • the scanning device 20 which has a pair of rollers 32, 34, serves to scan the thickness of the film strip 16 as a criterion for the intended roll change.
  • the pair of rollers consists of a stationary, but spring-loaded measuring roller 34 and a counter roller 32.
  • the measuring roller 34 is connected to an electrical or electronic contact device 36 which responds when there is a deviation from the normal thickness of the film strip 16. In the extreme case, the deviation can be the end of the film strip 16.
  • the film strip has kinks or other unevenness before its end, which leads to a response. Of course, defects that are not related to the end of the strip are also detected, the scanning of which makes a roll change necessary. The scanning ensures that only film tape is fed to the tube manufacturing machine, the thickness of which lies within predetermined tolerances.
  • the film strip runs after a deflecting roller 38 over the cutting table 22, to which a cutting device 40 with a knife 42 movable transversely to the strip direction is assigned.
  • a clamping device 46 Arranged above the cutting table 22 is a clamping device 46 which can be actuated by an actuating element 44 and which serves to clamp the film strip 16 during the cutting process and during the subsequent connecting process.
  • the stop device 24 has a rubber-tired, controllable stop roller 48 and a counter roller 50.
  • the stop roller 48 is braked after the scanning device 20 has detected a change in the thickness or the end of the film strip 16. However, the braking does not take place immediately according to the claim of the scanning device 20, but is delayed in order to advance the still good and therefore usable belt section 16 ′, which is located between the scanning device 20 and the cutting table 23 during the response.
  • the optical scanning device 26, which is assigned to a positioning device 52, is used to determine the corresponding length of the usable section 16 ′.
  • the Positioning device 52 is connected to the stop device 24 in order to actuate it at a point in time at which the end of a tube section is located at the knife 42.
  • the compensating device 28 has a compensating carriage 58 which is guided on a rail 54 and has a deflection roller 56.
  • a compensating device 28 forms a loop 64 of the film strip 16 between two guide rollers 60 and 62.
  • the tensile force of the compensating carriage 58 is dimensioned in such a way that the braking effect of a brake which constantly engages the winding mandrel 10 is overcome, which brake serves to maintain a tensile stress on the film strip.
  • the trimming device 30 is used to cut off at least one of the edges of the film strip 16 in order to obtain a clean, burr-free longitudinal edge.
  • the tape feed device 14 normally continues to run with the stop roller 48 braked, during which time the loop 64 is at least partially drawn in until the new tape start is connected to the running tape end.
  • the first winding mandrel 10 is fastened to an arm 66 of a swivel bar which can be rotated about a fixed axis of rotation 68.
  • a second winding mandrel 72 is fastened to the second arm 70 of the swivel bar, on which a second film supply roll 74 is placed.
  • a second winding mandrel beam 67 consisting of the two arms 66 and 70
  • another rotating body can also be provided, on which more than two winding mandrels are arranged.
  • the axes of all winding mandrels 10, 72 extend parallel to the axis of rotation 68 and are all arranged at the same distance from the axis of rotation.
  • the counter roller 32 of the scanning device 20 is assigned to the first winding mandrel 10 at the end of the arm 66.
  • the second winding mandrel 72 is assigned an identical counter-roller 32 'at the end of the arm 70.
  • the swivel beam 67 can be rotated or swiveled clockwise about its axis of rotation 68, so that after a swivel movement the two mandrels 10 and 72 and the two counter-rollers 32 and 32 'are interchanged.
  • the film strip 78 which is pulled up to a stop 76, is held in place by the start of the strip by a second clamping device.
  • This clamping device 80 has the film strip 78 on both sides engaging clamping fingers 82, which are fastened to a gear wheel and interact with a clamping body 84 arranged above the film strip 78.
  • a connecting device 88 which can be lowered onto the film band by means of an actuating element 86 and which can be, for example, an electrical resistance heater designed as a pulse band.

  • This guide consists of a groove in which the bearing 98 is guided without play in the radial direction to the axis of rotation 68.
  • This guide ensures that the measuring roller 34, which is spring-loaded in the direction of the counter-roller 32, responds to a change in the thickness of the film strip passed between the two rollers 34 by actuating the contact device 36 connected to the shaft of the measuring roller 34.
  • Such a contact device can have a sensitivity of 1/1000 mm, for example.
