Definitions

  • the present invention relates to a drive device for rotating a tape reel to be stamped.
  • the invention relates to a tape dispenser module stamped, equipped with at least one such drive device.
  • the invention relates to a stamping machine for the manufacture of packaging comprising at least one such drive device.
  • the invention also relates to a stamping machine for the manufacture of packaging with a unwinder module equipped with at least one such drive device.
  • a stamping machine presses patterns onto a sheet element.
  • the patterns for example texts and / or decorations most often metallized, are obtained by a form stamping or cliché.
  • the patterns come from portions of a film from one or more strips to be stamped.
  • the sheet elements are removed from an upstream stack, gripped by a conveyor, and successively fed into a platen-bearing stamping press.
  • the picture is mounted on the fixed upper bed of the press.
  • a stamping counterpart corresponding to the cliché is mounted on the movable lower bed base of the press.
  • hot stamping known as hot foil stamping
  • the plate is heated.
  • the metallized stamping tapes are conducted between the scroll plane of the sheet elements and the upper beam.
  • the movable lower bed will press the tape to be stamped against each sheet element between the plate and its counterpart to deposit the film portions thereon.
  • the lower bed base descends and the stamped sheet member is then released by the clip bar onto a stack in a reception, to make room for the next sheet member that follows.
  • the tape to be stamped is moved so that a new film surface is matched with the photograph.
  • the transport of the strips requires intermittent unwinding and advance means generally consisting of rollers against which the strips are gripped by pressure rollers.
  • the motorized drive of these rollers allows the intermittent advance of these bands.
  • the majority of the patterns deposited on the packaging can be made from strips to stamp low width, generally not exceeding 30cm. But it is sometimes necessary to resort to stamping strips of greater width, typically of the order of 50cm to 70cm. A set of narrower strips arranged side by side and whose cumulative total width reaches this order of magnitude can also be used.
  • the tape reels to be stamped are stored in an unwinder module.
  • the tapes are driven to be unwound.
  • the module is used to support the coils and feed the machine with the tape or strips.
  • the module is similar to a cabinet located at the back outside of these machines.
  • the module has a bearing structure in which are arranged one or more reel carriers each of which supports at least one reel. There are two systems for unwinding the tape to be stamped.
  • the document EP-1'588'968 describes one of the two systems, with a drive device of the coils mounted free to rotate on their respective carriers.
  • the device comprises a belt which manages the function of advance and braking of the unwinding of the reel and thus of the belt feed to be stamped from the machine. By rubbing the belt against both a drive shaft and the spool, rotation synchronization is guaranteed.
  • the belt of the device is stretched by a spring.
  • a second disadvantage observed is the difficulty of setting active position of several devices on a wide coil. Once a first device is placed on a coil of greater width, it is blocked by the drive shaft, because the coil and the drive shaft are coupled by the tensioned belt. When the operator must put in position a second device on the same coil, the belt of the second device attempts to rotate the coil already blocked by the first device. The operator must press very strongly and with great difficulty to put the second device on the reel. Forcing, the setting is difficult and the band is very heavily crumpled on the surface of the coil.
  • Another disadvantage is a gap in the operating zone. As a coil unfolds, it has less inertia but rotates faster. Without neglecting the hub inertia, the requested power is greater than for the full spool, in the case of a larger width spool. Due to the principle of the spring, the tension of the belt decreases and leads to a sliding of the latter on its surface at the end of the coil. In this case, a decrease in pace is mandatory to compensate for this phenomenon.
  • a main object of the present invention is to develop a drive device for unwinding a web roll in a unwinder module in a stamping machine.
  • a second objective is to make it easier and to reduce the time of placing a training device in the active position.
  • a third objective is to solve the technical problems mentioned for the document of the state of the art.
  • a fourth objective is to provide an unwinder module integrating one or more drive devices for one or more coils.
  • a fifth objective is to integrate a device into a stamping machine. Another objective is that of making a stamping machine with an unwinder module.
  • the device is characterized in that the return means are means, able to be disengaged and to be actuated to move the belt from the inactive configuration to the active configuration and vice versa.
  • the return means are no longer passive.
  • the device provides two functions. On the one hand, it couples the drive means and the coil through the tensioned belt. On the other hand, the tension of the belt is controlled throughout the course of the coil.
  • the biasing means maintain the belt in constant tension by following the course of the coil, thus eliminating the gap in the operating zone.
  • the tension of the belt is adaptable according to the power required, the quality of the hub, and the quality of winding of the band.
  • the coupling between the coil and the drive shaft is removed by the operator.
  • the belt is relaxed or weakly tensioned.
  • the disengageable and operable means ensure a tension of the belt after the active setting of the device. With the disengageable and operable means, the belt is tensioned at the last moment of the setting in active position. A belt that is loosened or weakly tensioned during the active position setting does not unnecessarily rotate the spool or block the spool. Positioning becomes much more ergonomic.
  • the strip is defined, by way of non-exhaustive example, as a metallized strip, for example aluminized, gold colored, or other.
  • an unwinder module for a stamping machine is characterized in that it is equipped with at least one stamping tape reel drive having one or more of the technical features described herein. below and claimed.

  • a front end of the arm 63 is held in the structure 42 of the device 41 while allowing pivoting .
  • the arm 63 is pivotable between a low inclination in the raised inactive position and a high inclination in the lowered active position.
  • a rear end of the arm 63 has a rounded concave shape similar to a hook. This form is complementary to the round profile of the ramp 61, which allows the arm 63 to remain attached to the ramp 61, regardless of the tilted position of the device 41. Thanks to such a connection, the arm 63 is mounted to slide on the bar 43, to be positioned and secured by the operator precisely, following the position of the device 41 on the bar 43.
  • the securing means 62 advantageously comprise a gripping member 64.
  • the gripping member 64 is provided at the rear end of the arm 63.
  • the gripping member 64 is here a gripping handle turned by the operator. The handle 64 moves a screw so as to secure the device 41 and maintain it on the ramp 61.
  • the securing means 62 advantageously comprise an actuator 66 connected to the return means, that is to say in this case to the jack 58.
  • the actuator 66 is in the form of a pusher and is mechanically connected to the handle 64.
  • the actuator 66 acts on two valves 67 which are in pneumatic connection with the jack 58 by means of a pneumatically actuated valve (not visible in the figures).
  • the operator first places the metallized strip coil 13 with the coil support 34 on the crosspiece 38, according to the layout of the sheet 8. Then, the operator moves the device 41 on the bar 43 and positions it so that the belt 46 is centered with respect to the width of the coil 22. If the width of the metallized strip 13 is large, and therefore if the width of the coil 22 is large, the operator shifts the first device 41 and adds a second device 41 next to the first.
  • the operator lowers the device 41, by rocking the structure 42 relative to the bar 43 and by pivoting the arm 63 relative to the structure 42, so that the belt 46 comes into engagement with the axis of drive 47 and with the coil 22.
  • the biased biasing means pneumatic jack 58 the operator does not have to force to pass the belt 46 from its inactive configuration to its active configuration.
  • the return means 58 being disengaged, the slider 56 and the movable roller 54 move easily.
  • the operator rotates the handle 64 in one direction, it simultaneously secures the device 41 to the ramp 61, and it actuates the cylinder 58 by causing it to engage.
  • the belt 46 is tensioned against the reel 22 to be unrolled.
  • Each stage 33 of the module 27 preferably comprises a compressed air distribution channel in the form of a tube 68.
  • the tube 68 is positioned substantially towards the middle of the module 27 and above the device 41.
  • the tube 68 is parallel to the drive shaft 47, the cross member 38, the bar 43 and the ramp 61.
  • the tube 68 is connected to the pneumatic cylinder 58 of the device 41, via the pneumatic valve.
  • the tube 68 supplies one or more devices 41 of the stage 33.
  • the devices 41 can be easily and quickly positioned, then connected, or disconnected, then stored aside, without creating any inconvenience.
  • the return means 58 may be replaced by an electrically actuated linear motor.
  • the device or devices 41 can be integrated in the supply and recovery station of tape 6.
