Definitions

  • the invention relates to a winding device for winding a web-shaped material according to the preamble of claim 1.
  • Web-shaped material for example plastic film
  • a web production device for example in an extrusion device
  • is often not processed directly that is to say "inline”, but initially wound into a winding device. Only these rolls are fed to a further processing machine.
  • finishing machines include printing machines, hose making machines and many other machines.
  • Other materials, such as paper, are wound in a winding device and fed in the form of coils of a further processing machine.
  • these windings are formed by winding the web-like material onto a winding core. Before the web-shaped material reaches this winding core or the winding on which already web-shaped material is wound, it is guided over a web guide roll.
  • This web guide roller can be arranged at a small distance from the winding core or to the winding (so-called "gap winder") or press the web-like material directly to the winding core or the winding. In the latter case, the winding device is referred to as a contact winder.
  • said web guide roll is typically the last roll over which the web-shaped material passes before it or while it reaches the winding core or the roll.
  • the winding is often associated with a pressing element, which can be adjusted to the winding
  • This pressure element is designed as a pressure roller in the rule.
  • the mechanism which is used to adjust the pressing elements to the winding comprises slides in which the pressure roller or the pressure element is mounted at both ends, the slides being displaceably arranged on mutually parallel rails.
  • These Schlenen are attached to walls, which also carry the winding cores.
  • the carriages supporting the pressure rollers are moved or removed by means of suitable adjusting means, such as a piston-cylinder unit, in the direction of the winding core.
  • the beats US 4 431 140 in that the pressure element is mounted at both ends in a lever arm pair forming lever arms, which are rotatably mounted, so that the pressure roller is pivotable about the bearing points of the lever arms. From this document is also known that at least one further winding core and at least one further rotatably mounted in lever arms pressure roller are provided.
  • the object of the present invention is to propose a winding device, in which the mechanics, which serves the queuing of the pressing element to the winding, requires less space.
  • the pivoting range of the lever arms is dimensioned so that a pressure roller can alternatively come into contact with two winding cores.
  • the pressure roller which does not have its own rotary drive, can be set in rotation by a rotating winding core.
  • the pressure roller can be accelerated before it touches the winding.
  • An acceleration of the pressure roller through the winding, on which already web-shaped material has been wound, can lead to damage to the web-like material.
  • the pressure element may be a pressure roller, which is rotatably mounted in this Hebelarmcru.
  • the lever arms are rotatably mounted in the walls in which the winding core is mounted. Since the bearing points of the pressure element in the lever arms and the bearing points of the lever arms in the walls do not coincide, the pressure element is ultimately pivotable about the bearing points of the lever arms. In this way, no rails are needed for the movement of the pressing element, but only lever arms which are rotatably mounted in one point. For this reason, the winding device according to the invention can be constructed much more compact than a winding device according to the known prior art.
  • turret winder Of crucial importance is the question of space requirements in so-called turret winder.
  • the winding core and the mechanism for adjusting the pressing element are attached to disks or plates which are rotatably mounted in the machine frame. At least one second winding core and at least one further mechanism for adjusting pressure elements are respectively mounted or fastened to these disks or plates.
  • a turret winder serves after a Winding was finished, the rapid Anwickeln formed by a cut new web start on the second core.
  • the winding device according to the invention therefore comprises the mentioned features of a turret winder.
  • the space requirement of the mechanism for adjusting the pressing element directly affects the size of the discs or the plates and also the drive power, which is necessary for their rotation in the machine frame.
  • the invention also relates to a method for continuously winding a web-shaped material to wind according to claim 9. Further method steps, which belong to the method according to the invention are described below in the context of the present description.
  • Fig. 1 shows a winding device according to the prior art.
  • the web-shaped material 2 which is supplied in the direction A of the winding device, guided over the contact roller 3.
  • the contact roller 3 is attached to the winding 4, which is wound on a winding core 5, employed, so that the run of the contact roller 3 web-like material is placed on the winding.
  • a pressure roller is employed on the winding 4, which presses the uppermost layer of the sheet-like material 2 with pressure to the winding 4 to prevent air pockets. Due to the strength of the pressure, the so-called winding hardness can be determined.
  • the winding core 5 is rotatably mounted at both ends in disks, of which only the rear disk 7 is shown.
  • the discs are in turn rotatably mounted in the machine position not shown.
  • the contact roller 3 is also mounted on the machine frame via elements that allow movement of the contact roller 3 relative to the winding core 5.
  • the pressure roller 6 is mounted on slides not shown in guides 8, wherein the guides are attached to the discs. With the help of piston-cylinder units or other suitable drives the pressure roller 6 can be moved relative to the guides and thus relative to the winding core 5.

  • the guides 10 also carry in this slidable carriage a second pressure roller 11 which is associated with the winding core 9.
