Definitions

  • the invention relates to a device, a web-processing machine and a method for unwinding web-like material.
  • sheet-like material can be understood in this context, inter alia flat webs or tubular webs.
  • Web-like material may also be tubular material.
  • register For machines that already process printed, web-shaped material, such as in paper tube machines, it is also important that the web ends of the old and the new roll are connected in register. Under register exactly understands the expert in this context, to connect a specific point of a new material web with a matching point of an old material web. For example, register marks can be applied to the material web for this purpose.
  • the register accuracy usually does not matter if the unwinding device is in front of a printing machine.
  • Such a Wendewickler which is used in functional relationship with a printing machine as a settlement, is also in the DE 19 66 795 A1 shown.
  • the register accuracy exceptionally plays a role.
  • the turret winder used in functional connection with printing machines have the disadvantage that they are mechanically very complex and therefore expensive. This circumstance stems from the fact that the winding positions of the turret winder are movable with a rotary or pivoting movement in the device. The suspension and movement of the often heavy winding on pivot levers or turning discs leads to the specified mechanical effort.
  • the DE 41 07 254 A1 shows a device for connecting the ends of webs of material, which are supplied by winding a packaging machine.
  • the reels are stored one behind the other in different storage locations.
  • the material web ends are connected register-accurate register - at the already partially developed tracks - in a dedicated connection device.
  • the connection of the web ends takes place only when part of the web is already unwound from the new roll.
  • the reels and the associated web ends rest, ie they have the speed zero.
  • the machine is supplied from a web store with web-shaped material.
  • the US 3,189,293 A. shows an unwinding, with which a so-called flying roll change - that is, a roll change while the web is running - can be made and forms the closest prior art
  • a device according to the invention is less complicated, since at least one winding point is stationary, so that the respective winding point may not have to be moved with the winding anchored there.
  • stationary in this context usually only the radial direction of the winding of the winding position.
  • the radial direction is to be understood in cylindrical coordinates.
  • the winding position can be movable.
  • the unwinding can be set to different winding formats (especially width of the sheet material).
  • the first winding point can be charged with a first winding.
  • This first winding can be moved from the winding transport lever in the second winding position.
  • a second, new winding can be introduced into the first winding position.
  • the transport from the first to the second unwinding point can also be initiated as follows.
  • the residual length on the first (old) reel can be monitored by a sensor and sent to a controller via a suitable data line. If there is only a certain residual length left on the old reel, the control unit can initiate the transport of the (old) reel from the first reeling point to the second reeling point.
  • the winding transport lever is associated with a latching and moving mechanism which moves the lever or holds it in an angular position.
  • This latching and moving mechanism preferably comprises a piston cylinder.
  • the winding transport lever includes the second winding position when the winding transport lever carries a winding and is pivoted away from the first winding position.
  • the latching mechanism can provide the opportunity to set the winding transport lever acted upon by the winding in different angular positions. In this way, therefore, the position of the second winding point to the first winding position can be varied with little effort. Thanks to this option, different sized reels can be optimally held in the winding stations.
  • the first winding position is fixed, while the second is movable by the pivoting movement of the winding transport lever.
  • the winding position of the winding position actually taken during winding is variable. So can the angular position of the lever be adjusted differently, so that among other things different winding diameters can be taken into account.
  • a device according to the invention can be made very compact. This circumstance is generally of great use, since space in machine shops is scarce and expensive. The advantage comes into play particularly when, in special application situations - as in connection with devices for forming multilayer paper hoses - a large number of unwinding devices are used in front of a processing machine.
  • the web joining device has at least two rollers as contact pressure means with which the first web can be brought to the circumference of the second web winding and can be connected there to the second web.
  • the at least two rollers of the pressing means are coupled together via a coupling element.
  • a coupling element for example, offers a coupling rod.
  • the coupling element it is also advantageous to rotatably support the coupling element at a joint, wherein the joint allows rotation of the coupling element along an axis which is substantially parallel to the axis of the second coil.
  • the at least two rollers of the pressing means can optimally cling to the new winding for connecting the tail ends.
  • a positioning device is provided, with which the contact pressure against the second winding can be adjusted and with which the contact pressure at variable winding diameter in the same angular position ( ⁇ ) of the coil against the peripheral surface of the coil can be adjusted.
  • the adjusting device comprises a frame, on which the pressing means is articulated and which (frame) in turn is articulated on the winding transport lever.
  • the positioning device for the first web comprises a frame to which an actuator, such as a reciprocating piston, is articulated.
  • This actuator provides the force for the employment of the pressing means to the second winding.
  • the adjusting device comprises a first actuator, with which the frame can be adjusted in the direction of the second winding.
  • the actuator can consist of a reciprocating cylinder. It should be noted that the winding transport lever - with the old, first winding - only so far pivots that the stroke of the actuator - preferably piston cylinder - sufficient to provide the adjusting device for connecting the tail to the new winding.
  • the frame can be hinged to the winding transport lever and the adjusting device such that the reciprocating piston at the various angular positions of the lever - which depend on the diameter of the winding - can always take approximately the same distance from the peripheral surface of the winding.
  • the surface of the second roll is always in the working range of the unit pressing-actuator.
  • a storage device for the sheet-like material which in the
  • the storage device advantageously consists of at least three rollers, of which at least one roller can change its relative position to the other two rollers. Often this roller is called “pendulum roller”.
  • the sheet material is guided meandering around these rollers.
  • the relative distance that the at least one pendulum roller has from the fixed rollers determines the track length stored in the web storage device. This distance of the pendulum roller from the fixed rollers can also be referred to as the "stroke of the pendulum roller".
  • the storage device comprises a drive, with which the "stroke of the pendulum rollers" is controllable, so that the length of the path stored in the storage device is controllable.
  • the storage device can also comprise a piston cylinder which can exert a force on the material web in the direction of the store, for example in order to fill an emptied store.
