Definitions

  • the invention relates to a device for coreless winding of a web of material fed continuously and spaced apart from one another with transverse perforations along a transverse perforation to supply rolls with two winding stations arranged in a machine frame, which are rotatably mounted and provided with a rotary drive, freely projecting into them relatively extendable winding position extendable and retractable in their unexpanded winding pins, wherein during the winding in one winding point the web is passed between the winding pins of the other winding point and the winding pins after Switching the web to the new winding point from its retracted position to the web between them to be extended position.
  • This known device is structurally relatively complex because the cantilevered winding pins not only have to be extended and retracted essentially over the entire width of the web to be wound up, but because they have to be spread so far relative to each other when extending that the web runs smoothly between the Winding pins can be passed through to the other winding point.
  • the object of the invention is therefore to provide a device of the type specified at the outset with which the supply rolls can be wound with smaller axial displacement paths and radial spreading movements of the winding pins.
  • each winding point on each side of the web has two winding pins which are essentially aligned with one another and which perform their spreading movements relative to one another in planes parallel to one another and which have at least a distance in the transverse direction of these planes which is necessary for the trouble-free passage of the material web is.
  • winding stations or winding heads with winding pins are provided on both sides of the web, these need only execute short axial extension and retraction movements in order to securely grasp and release the web, because the winding axes guaranteeing good winding are already defined by the bilateral detection of only the edge regions of the web . Since the winding pins already have a sufficiently large transverse spacing relative to one another to ensure a trouble-free passage of the material web, they only have to make relatively small spreading movements after extending into their winding position, because there is sufficient loosening of the winding pins before pulling them out in the completely wound roll if these are returned to their unspread position.
  • the winding pins only need to perform a spreading movement which, after returning to their unspread position, is sufficient to loosen the winding pins in the finished roll winding and therefore only needs to be very small, while in the known device the winding pins travel over a larger radial distance, than would be required for loosening per se, must be spread in order to create such large distances between the winding pins that the web can run between them without interference.
  • winding heads with winding pins which, in their non-spread position relative to one another, are so far apart that the web can run between them.
  • the winding pins must have such a large, freely projecting length that they extend beyond the winding web that they can be bent into their spread position by means of an expansion cone.
  • US-PS 35 80 522 are in an intermittently working winding device with only one winding point, in which the web for separation from the wound web section on two Places must be clamped in order to separate them between the clamping points, extendable and retractable pairs of winding pins acting on both sides of the web, which are spread out in their extended position by a spreading wedge and spring back into their unexpanded position by pulling back the spreading wedge.
  • the pliers-like winding pins must be spaced so far apart that the web can be passed between them without interference, so that no corresponding measures are provided.
  • a winding device with a frame-fixed winding point consist of two opposite pairs of winding pins provided with a rotary drive, which can be pushed towards each other to capture a material web to be wound in sections without a core, so that the two winding pins in each case move the web therebetween einfas - sen, and are retractable to release a roll over the side edges of the web also.
  • the known device is used for intermittent winding of web sections which are separated from an endless web, in which the winding pins, which are displaceable towards and away from one another in a common plane, perform a pincer-like opening movement for gripping the web and a corresponding closing movement when they are retracted , so that the frictional engagement of the winding pins with the winding is reduced and the winding formed can be easily stripped from it.
  • the wrap still connected to the web then falls into a collecting trough.
  • pairs of clamping jaws which clamp the web are provided on both sides of the winding point and a separating knife between them.
  • the web clamped between the jaws is tightened by a tensioning device, so that the appropriately aligned and spread winding pins for grasping the web are stacked again can be advanced.
  • the known winding device does not allow winding and separation of a continuously fed web.
  • the web must not only be stopped to separate the respectively formed roll with a predetermined section length, it must also be clamped on both sides of the winding point by special clamping devices and cut through a special cutting device, which not only limits the winding performance, but also requires additional design effort.
  • the winding stations have support plates with bushings rotatably mounted in them and provided with the rotary drives, that the winding pins consist of angle levers which are pivotably mounted on a common transverse axis of a support piece which is rotatable at the front end of a scissors is aligned with the central axis of the bushing aligned piston rod of a pressure-medium piston cylinder unit that is fixed to the frame, that the longer, the winding pins forming scissor-like legs of the bushing are guided in a longitudinally displaceable manner and acted upon by springs in the direction of their unexpanded position and that the shorter legs of the angle levers, which are angled approximately at right angles, open Support opposite sides of the outward-facing end faces of the bushings towards the end of the feed movement in such a way that their longer legs that pass through the bushings are spread apart.
