Definitions

  • the present invention relates to a strip unwinding device for a sheet-shaped element stamping machine.
  • the invention also relates to a stamping machine configured to deposit on each sheet of the gold or metallized film from at least one strip to be stamped.
  • Each strip to be stamped is packaged in the form of a reel which is rotatably mounted on itself, and which is unwound by means of a feed shaft pulling directly on the strip.
  • this advance shaft is destined to rotate at variable speed since the tape advance takes place sequentially within the platen press.
  • the coil has a mass and therefore a relatively large inertia, it proves to be particularly difficult for it to follow such a succession of accelerations, decelerations and time delays.
  • a tape unwinding system which is capable both of accumulating tape in a pre-unrolled form downstream of the reel, and of delivering the correct length of pre-unrolled tape at each load on the advance shaft.
  • the presence of such a tape reserve in the interposed position then advantageously makes it possible to unwind the reel at a substantially constant speed, while allowing the advance shaft to operate at variable speed.
  • a tape unwinding system which takes place between the reel and the advance shaft, and which implements two series of references whose spacing is likely to vary according to the tape advance.
  • the two series of returns are arranged so as to define a tape circulation path, the shape of which describes a succession of loops which circumvent each return respectively by passing alternately from one series of returns to the other.
  • One of the series of transmissions is mounted so as to move relative to the other, between a position close in which the series of returns are arranged close to each other so as to define a strip circulation path of minimum length, and a remote position in which said series of returns are arranged at a distance from one of the other so as to define a strip circulation path of maximum length.
  • This tape unwinding system can however generate jolts due to the inertia of the reel, in particular during the transient phases of start-up, acceleration stop and deceleration. These jolts can stretch the strip to be stamped and damage it.
  • a reel braking device is also generally necessary to guarantee an optimum web tension and not to unwind the reel more than necessary when the advance shaft slows down and stops.
  • Another disadvantage of this system is that it can prove difficult to implement, in particular following a production malfunction.
  • Another problem also is that the outsourced system requires a space on the ground and a strip deployment between the reel and the press which are not negligible. This long length of unwound strip can affect the accuracy of placement and increase the length of strip consumed.
  • the document WO2010/063353 describes a web unwinding system comprising a central roll and a satellite roll.
  • the axis of the satellite roller is mounted on a rotation system whose axis coincides with the axis of the central roller and allows the satellite roller to move around the central roller.
  • the movement of the satellite roller makes it possible to vary the advance of the strip at the exit of the system.
  • the satellite roller being large enough to allow a sufficiently large variation in the advance of the strip.
  • One of the aims of the present invention is to propose a device for unwinding a strip to be stamped which makes it possible to at least partially solve at least one of the aforementioned drawbacks.
  • the strip to be stamped can thus be pre-unrolled at constant speed from the stamping reel, pulled by the satellite roller.
  • the tape can be fed out of the tape unwinding device at the variable forward speed.
  • the length of accumulated strip to be stamped varies with the angular displacement of the satellite roller around the central drum which itself varies, due to the planetary drive, as a function of the difference in the speeds of rotation of the central drum and of the outer ring. It is thus possible to accumulate strip to be stamped and then to deliver the strip to be stamped accumulated each time the feed shaft is actuated.
  • the tape unwinding device is more compact than a “linear” system of the prior art because it can be integrated directly into the machine. It is also more robust and easier to implement. The distance between the reel and the press can be small, which makes it possible to increase the strip laying precision and therefore to reduce the strip consumed.
  • the pitch radius of the central pinion corresponds to the outer radius of the central drum.
  • the diameter of the satellite roller has a dimension smaller than the radial gap located between the pitch diameter of the outer crown and the outer diameter of the central drum.
  • the satellite roller is rotatable.
  • the planetary drive device further comprises a toothed wheel mounted on the planet carrier, integral in movement with the planet roller and meshing with the outer crown.
  • the pitch radius of the toothed wheel corresponds for example to the outer radius of the satellite roller.
  • the satellite roller is fixed to a planet carrier of the planetary drive device, the satellite roller being porous and having an internal cavity configured to be placed in communication with pressurized air so as to form an air cushion under the strip to be stamped.
  • the planetary drive device comprises a guide integral in movement with the satellite roller around the central drum, the guide being capable of being interposed between two strands of the pre-unrolled strip to guide an outer strand of said strip.
  • the guide comprises between one and ten, such as five, additional satellite roller(s), the additional satellite roller(s) and the roller satellite inscribed in a circle.
  • the additional satellite roller(s) may be rotatable.
  • the guide further comprises for example as many toothed wheels as additional satellite rollers, the toothed wheels being mounted on the planet carrier and integral in rotation with a respective additional satellite roller and meshing with the outer ring.
  • the guide comprises a metal element fixed to the planet carrier, the metal element having between one and ten, such as five fold(s) or undulation(s), the fold(s) or undulation( s) and the satellite roll fitting into a circle.
  • the diameter of said circle corresponds to the pitch diameter of the outer crown.
  • the outer crown is configured to be driven in rotation at a constant speed substantially equal to an average value of the variable advance speed.
  • the axis of the central drum is capable of being driven in rotation at a variable advance speed by a motor of the strip unwinding device to form an advance shaft. This reduces the number of parts.
  • the subject of the invention is also a machine for stamping elements in the form of sheets configured to deposit on each sheet gold or metallized film from at least one strip to be stamped, characterized in that it further comprises at least one device tape unwinding as previously described.
  • upstream and downstream are defined with reference to the longitudinal direction of movement of the sheets D ( Figure 1 ).
  • the sheets move from upstream to downstream, generally following the main longitudinal axis of the machine, in a rhythmic movement with periodic stops.
  • sheet-shaped elements and “sheets” will be considered equivalent, and will concern elements made of corrugated cardboard as well as flat cardboard, paper or any other material commonly used in the packaging industry.
  • sheet or “element in sheets” or “element in the form of sheets” refer very generally to any printing medium in the form of sheets such as, for example , sheets of cardboard, paper, plastic, etc.
  • FIG. 1 represents an embodiment of a stamping machine 1 capable of depositing on each sheet of the gold or metallized film from at least one strip to be stamped 2, in particular for the manufacture of packaging.
  • This machine 1 is conventionally composed of several workstations 100, 200, 300, 400, 500 which are juxtaposed but interdependent one by one to form a unitary assembly able to process a succession of sheet-like elements.
  • a transport device 600 is also provided to individually move each sheet from the exit of the feed table 200 to the receiving station 500, including through the stamping station 300.
  • the sheets are successively removed from the top of a stack by a suction gripper which transports them to the directly adjacent feed table 200 .
  • the sheets are put into a sheet by the suction gripper, that is to say placed one after the other so as to partially overlap.
  • the entire web is then moved along a platen towards the stamping station 300, by means of a belt transport mechanism.
  • the head sheet can be systematically positioned with precision by means of frontal and lateral cleats or by a register system.
  • the workstation located just after the margin table 200 is therefore the stamping station 300.
  • the latter has the function of depositing on each sheet, by hot stamping, the metallized film which comes from a strip to be stamped 2. It uses for this a platen press 310 inside which the stamping operation takes place conventionally, between a heated upper platen 320 which is fixed, and a lower platen 330 which is mounted to move along a vertical back-and-forth motion.
  • the strip supply station 400 is responsible for ensuring both the supply of the machine 1 with stamping strip 2 as well as the evacuation of this same strip 2 once it has been used after having passed through the station. stamping 300.
  • the process of processing the sheets in the stamping machine 1 ends in the receiving station 500, the main function of which is to repackage the previously processed sheets into a stack.
  • the transport device 600 is for example arranged so as to automatically release each sheet when the latter finds itself in line with this new stack. The sheet then falls squarely on top of the pile.
  • the transport device 600 implements a series of gripper bars which are movably mounted via two chain trains 620 arranged laterally on each side of the stamping machine 1.
  • Each chain train 620 traverses a loop which allows the gripper bars to follow a trajectory successively passing through the stamping station 300, the tape supply station 400 and the receiving station 500.
  • the set of gripper bars will start from a stopped position, accelerate, reach a maximum speed, decelerate, then stop, thus describing a cycle corresponding to the movement of a sheet from a work station to the station.
  • Chain trains 620 move and stop periodically so that during each move all of the gripper bars engaged with a sheet are moved from one station to the adjacent downstream work station. Each station performs its work in synchronism with this cycle which is commonly called the machine cycle. Workstations start a new job each time a machine cycle begins.
  • the strip supply station 400 comprises at least one strip unwinding device 10 capable of accumulating the strip to be stamped 2 in a pre-unrolled form downstream of at least one stamping reel 3 and of delivering the pre-rolled tape at each load on a feed shaft of machine 1.

  • the tape unwinding device 10 comprises a central drum 11, a satellite roller 14 and a planetary drive device 15.
  • the central drum 11 is configured to be driven in rotation at a variable forward speed, integral in rotation with an axis 16 of the tape unwinding device 10.
  • the forward speed controlled by the machine 1 increases then decreases (we speak of "advance") and cancels out.
  • This step of advance causes the band to be stamped 2 to coincide with a sheet for depositing the metallized film by stamping according to a predefined program in the machine 1.
  • the advances can be identical or different between each stop or different between at least two successive and periodic stops.
  • the satellite roller 14 has an axis 21 arranged parallel to the axis 16 of the central drum 11.
  • the satellite roller 14 is capable of rotating around the central drum 11.
  • the pre-unrolled strip is likely to wrap around the central drum 11 (over less than one turn) under the effect of the displacement of the satellite roller 14. More specifically, the pre-rolled strip is wrapped around of the central drum 11 after having bypassed the satellite roller 14 forming a return of the pre-unrolled strip ( Figures 10 and 11 ).
  • the planetary drive device 15 comprises a central pinion 12, an outer crown 13, a planet carrier 17 and at least one planet pinion 20 ( Figure 4 And 5 ).
  • the central pinion 12 is integral in rotation with the central drum 11 and it is coaxial with the central drum 11 ( Figure 6 ). They are for example fixed to the axis 16 ( Figure 4 ). A bearing supports for example the opposite end of the axis 16.
  • the pitch radius of the central pinion 12 corresponds for example to the outer radius of the central drum 11 ( Figure 6 ).
  • the outer crown 13 is toothed ( Picture 7 ). It is coaxial with the central pinion 12 and is configured to be driven in rotation at constant speed.
  • the term "constant" means a substantially constant speed, that is to say for example varying over less than +/- 10% of an average speed.
  • the constant speed is for example substantially equal to an average value of the variable forward speed.
  • the direction of rotation of the outer crown 13 is opposite to the direction of rotation of the central drum 11.
  • the direction of rotation of the outer crown 13 is chosen so that the rotation of the outer crown 13 unwinds the stamping reel 3.
  • the outer ring 13 is for example carried by a support 19 rotatably mounted on the axis 16 by means of a bearing ( Figure 4 ). In the axial direction, the central pinion 12 is interposed between the central drum 11 and the support 19 of the outer crown 13.
  • the satellite roller 14 has, for example, a diameter of a dimension smaller than the radial gap located between the pitch diameter of the outer ring 13 and the outer diameter of the central drum 11, which allows an inner strand of the strip to be stamped 2 s 'rolling on the central drum 11 to interpose without getting stuck between the satellite roller 14 and the central drum 11.
  • the planet carrier 17 is integral in movement with the planet roller 14 around the central drum 11 and coaxial with the central drum 11.

  • the at least one satellite pinion 20 is mounted on the planet carrier 17. It meshes on the one hand, the outer crown 13 and on the other hand, the central pinion 12 to be driven in rotation in one direction or the other around the central drum 11 as a function of the difference in the speeds of rotation of the central drum 11 and of the outer ring 13.
  • the movement of the at least one satellite pinion 20 causes the movement of the satellite roller 14 around the central drum 11 which varies the length of the pre-rolled strip.
  • the planetary drive device 15 comprises for example four planet pinions 20 mounted on the planet carrier 17, for example inscribed in a cross shape ( Figure 5 , 8 and 9 ).
  • the planet gears 20 transmit the drives of the outer crown 13 and of the central pinion 12 to the planet carrier 17 integral in movement with the planet roller 14.

There Picture 10 thus illustrates a first extreme position of the satellite roller 14 for which the reserve of pre-unrolled strip is maximum.

It is thus possible to accumulate strip 2 to be stamped and then to deliver the strip 2 to be stamped accumulated at each request of the advance shaft.
  • coils 3 can also be unwound with the tape unwinding device 10 if these are delivered to the stamping station 300 with the same feed speed.

  • the folds or undulations 30 are for example regularly spaced, for example on an arc of a circle between 90° and 180°.
  • the outer strand of the pre-rolled strip can thus slide over the folds or undulations 30 almost without friction.
  • the strip 2 to be stamped coming from the stamping reel 3 can thus be guided by the folds or undulations 30 so that the outer strand approximately follows the pitch diameter of the outer crown 13.
