Definitions

  • the invention relates to a device for unwinding rolls sheets or ribbons and in particular rolls of paper used in the printing and arts industry graphics.
  • the invention relates more particularly to a device of the so-called unwinder type comprising an accumulator magazine allowing to connect the ends of two successive rollers without requiring an extended shutdown and without it being necessary to iron one end of a strip in a pulley path that is long and difficult to access.
  • the invention also makes it possible to make a cut and a simultaneous bonding, end to end, of the ends of two strips unrolled from two successive rolls.
  • the document EP-A-0 301 989 describes a device for positioning and connecting of rolls of sheets of paper and the like comprising a moving carriage vertically and which includes a motor to allow rapid acceleration of the roller.
  • the invention aims to improve existing devices by ensuring that there is no need to introduce manually a mandrel inside the rollers and she allows to execute all operations by means of organs mechanical.
  • the spindle which supports the roll, is itself supported at its two ends, which ensures great stability during the course.
  • the device for placing and for connecting rolls of paper sheets and the like comprises at least a first carriage mounted to be movable along guide means, said first carriage comprising on a side of an upright provided with slides for guiding a second carriage movable axially along the upright and guided by the latter, said second carriage being provided with a spindle engaged in a roller raised by movement of the protruding spindle of said roller to be engaged by displacement of the first carriage in a rotating coupling member mounted at a fixed position so that said pin is supported at both ends when the sheet or strip unwound from a roll has passed in a pulley path.
  • Fig. 1 is a schematic elevation of the setting device in place and connecting sheet rollers according to the invention.
  • Fig. 2 is a 90 ° turned elevation of the fig. 1, one of the elements of the device being illustrated in a particular position.
  • the device illustrated in the drawing comprises a frame 1 inside which is arranged an accumulator store 2 for a strip 3 constituted for example by a sheet of paper wrapped around pulleys 4, 5 forming part of a path pulleys and arranged like mittens held under constant tension by a jack 6 or a counterweight system or the like.
  • the pulleys 5 are movable along a guide 7 so that the strip or sheet passing over the pulleys constitutes a reservation.
  • the frame 1 is connected to a secondary frame 8 by a gantry 9 or another means ensuring good rigidity of the frames, one compared to each other.
  • the space between frame 1 and secondary frame 8 includes guide means 10, for example rails preferably embedded in the ground for a carriage 11 comprising advantageously two side members 12 joined by a cross member 13 to constitute a U-shaped chassis carried by wheels 14.
  • the above chassis supports, by its cross 13, an amount 15 comprising slides 16 for guiding a second carriage 17 movable along the slides 16 by means of a operating member 18 for example a pneumatic gun actuating a mechanical cylinder 19 or the like.
  • the carriage supports a pin 20 (fig. 2) on which is engaged a roller 21 for example a roll of paper.
  • the spindle 20 is provided with a locking means 22, for example a mandrel or other pneumatic or mechanical element, for locking the spindle and the paper roll together.
  • a flywheel 18 a is used for expanding the mandrel and therefore for blocking the roller on the spindle.
  • the device comprises two identical carriages 11 and 11 has two rollers 21, 21a.
  • Fig. 1 shows that an engine assembly 27 a , identical to the engine assembly 27, is disposed beyond the secondary frame 8 on rails or other guide means 10 a , also embedded in the ground.
  • the sheet 3 unwound from the roll 21 passes through a path of pulleys comprising a capstan 28 and guide pulleys retainer 29 and return 30 leading to the store pulleys accumulator 2.
  • the strip 3 has unwound from the roller 21 a passes over a capstan 28 a and retaining pulleys 31 holding this strip against the strip 3 over part of its path.
  • Bonding and cutting members 33 known in themselves are arranged on the part of the unrolled bands attached to each other to allow their junction at the end of unwinding successive rolls.
  • the device works as follows:
  • a first roller for example roller 21, is brought in rolling it on the ground or moving it by another medium next to one of the carts, for example the carriage 11, while the latter is separated from the frames 1 and 8.
  • the carriage 11 is then advanced after adjusting the height of the spindle 20 by means of the operating member 18 to bring it coinciding with the roll core. Taxiing on the ground roller 21 is facilitated by the embedding of the rails.
  • the actuator 18 is again actuated to move pin 20 in the direction for which it raises the roller 21 which is then blocked by the locking means 22.
  • the carriage 11 is then moved again to bring it between frames 1 and 8 making sure that its nut 24 enters the coupling member 25.
  • the centering cone 23 ensures, moreover. precise maintenance of the free end of pin 20 which is thus suspended, on the one hand, from carriage 17 and, on the other hand, to the coupling member 25, comprising an appropriate bearing but not shown. Both the ends of the spindle are thus supported in rotation.
  • the sheet or external strip of the roller 21 is then brought to pass over the capstan 28 and the pulleys 29, 30 then the pulleys 4, 5 of the accumulator magazine 2 in order to be carried as shown in 3 1 to a device for use.
  • the second carriage 11 a is loaded in a similar manner by means of the roller 21 a and it is moved so that its pin 20 is connected to the corresponding coupling member 25 of the motor assembly 27 a .
  • the strip 3 has from the roller 21a is placed on the capstan 28a and the guide pulleys 31 corresponding to the pulleys 29 followed by the strip 3.
  • the setting operation of the roller 21a and thus of the strip 3 has can be performed while using the strip 3 unwound from the roll 21.
  • the strip 3 is slowed down by the drive motor of the hub 25 and the spindle 21, until complete stop.
  • the unwinding device 30 is then blocked, by means an electromagnetic brake not shown, for example so as to maintain the complete stop.
  • the strip 3 1 continues to be called by the machine, which is then supplied by the reserve of the accumulator magazine 2.
  • the two strips of the tint roller 21 and of the new roller 21 a are then cut simultaneously by the cutting member 33, then glued using two adhesive strips, prepared on the jaws of the gluing member 32.
  • the device 30 is then released, then the new roller accelerated until the storage tank 2 is filled.
  • a new roller 21 can be put in place as explained in the above.
  • the accumulator magazine 2 allows uninterrupted use of the strip it contains by moving the pulleys 5 when the end of the strip coming from one or the other is immobilized. rollers 21 or 21 a .
  • the coupling member 25 can be carried by a free bearing when the unwinding rolls is provided by capstans or other means analogues.
  • the device may include a single carriage 11 for a single roller 21. In this case, a brake is provided to temporarily immobilize the end of strip, for example at the capstan 28.
