Definitions

  • the present invention relates to a machine and a method of winding flat and flexible elements arriving continuously and partially overlapping, such as sheets or printed envelopes, for storing and transporting them while waiting for unwinding operation by another apparatus using these elements.
  • the storage reels comprise a central drum having a hub inserted in the winding machine and a cylindrical outer circumferential part on which spirals a continuous flow of flat elements aligned along the longitudinal axis of movement and partially overlapping.
  • a flexible band attached at one end to a mid-point of the drum is wound together with the flat elements, so as to mark a separation between the different winding layers and to tighten them on the drum to hold the assembly together. in position.
  • the flat elements generally come from a continuous printing machine and are reeled to be stored right out of the machine.
  • the reels are then delivered to the next workshop, which for example makes journals by assembling different sheets from multiple reels or automatically envelops documents by inserting them into envelopes from a reel.
  • the reel is unwound to extract the flat elements, simultaneously the tape is unrolled and is stored temporarily on a hub. Once the reel is empty, the tape is put back on the drum by winding it on, then the whole is returned to the starting shop to serve again.
  • the flexible band is not perfectly centered over its entire length relative to the flat elements, the coil is then deformed.
  • the coil consisting of a stack of flexible elements and the band ensuring a clamping covering only a central portion of the flat member, the non-maintained side portions are deformed. If the band moves laterally during winding, the deformation of the flat elements is irregular, which can cause problems for downstream automatic machines that can not then grasp the elements.
  • the geometry of the coil is also in this case bad with deformed side faces that are no longer flat. This problem, especially in the case where it is combined with an improperly adapted tape tension during winding, can lead to an axial shift of the drum or part of the bobbin during handling which may lead to complete collapse. of the coil.
  • the present invention is intended in particular to avoid these disadvantages and to provide the realization of a winding machine a simple effective solution, to ensure a good winding quality of the coils.

  • the machine further comprises a motorized means for adjusting the transverse position of the hub providing lateral displacement relative to the coil to keep a constant alignment of the band during winding.
  • An essential advantage of the winding machine according to the invention is that the transverse position of the strip being strictly ensured by the motorized means, the wound strip is well aligned on the same plane and in the axis of the flat elements which ensures to these elements a uniform deformation and to the coil a good symmetry.
  • the adjustment means being motorized, it can be very responsive and ensure a good position from the beginning of the winding for all types of winding defects found on drums returning empty with their band wound on it.

  • the motorized means for adjusting the transverse position of the hub relative to the coil uses to control its movement during winding a fixed sensor relative to a frame of the unwinding assembly giving information on the lateral position of the strip at a location near the unwinding point of the hub strip.
  • the motorized means for adjusting the transverse position of the hub is used to laterally align the strip on the hub during a prior operation of winding the strip on the hub from the drum.
  • the lateral alignment of the band with respect to the hub during the prior winding operation on this hub can use a fixed sensor relative to the carriage providing information on the lateral position of the web at a location near the winding point of the web on the hub.
  • the sensor giving information on the lateral position of the strip may be an optical sensor.
  • the braking device comprises a rotary electric machine controlled by a control for delivering a braking torque or a motor torque.
  • the belt drive of the conveyor feeding the flow of flat elements can be done by a tangential support of this belt on the outer periphery of the coil, and a sensor can give an indication of the movement of the belt and the direction of this movement to control the electric machine and provide either a braking torque if the winder is being wound, or a motor torque if the winder rotates in the other direction for a prior operation of winding the band on the hub .
  • the traction on the belt produced by the braking torque delivered by the electric machine is regularly decreasing during a winding operation.
  • the decrease of the traction on the web during a winding operation can be controlled by a sensor giving information on the outer diameter of the coil being wound.
  • the decay of the traction on the web between the beginning and the end of the winding is in a ratio of between two and four.
  • the flat elements wound on the coil are envelopes. They may have a width greater than the height and be arranged transversely with respect to the flow along the width.
  • the wound envelopes have a width of about 19 to 24 centimeters and a height of about 11 to 18 centimeters, and the tension the band is of the order of 300 Newton at the beginning of the winding and 100 Newton at the end.
  • the envelopes of envelopes made are used downstream by an automatic enveloping machine which unrolls these coils to extract one from the envelopes and automatically insert a mail.
  • the invention also relates to a method of winding a coil from a continuous flow of flat and flexible elements which are aligned along a longitudinal axis and overlap partially.
