Abstract

The present invention relates to an arrangement for guiding a fiber web (W) to be handled from a surface of a roller or belt cycle during normal operation in a paper-/tissue paper-/cardboard- or after-treatment machine so as to prevent the fiber web from winding around the roller or the belt cycle. The arrangement has a scraper-type blade (5) extending in a transverse direction of the roller (6) or metal belt cycle and detachably arranged in a surface of the roller or belt cycle during normal operation of the fiber web (W). The blade has pressure pipes (2, 3) for guiding the fiber web (W) using rapid-motion against the surface of the roller (6) or belt cycle.

Description

Device in paper machine/toilet paper machine/board machine or the post-processor
Technical field
The present invention relates to a kind of be used for when width of cloth material input or width of cloth material disconnect will the pending fiber web of paper machine/toilet paper machine/board machine or post-processor from the surface of the roller that is arranged in machine or the surface guiding that is arranged in the band circulation of machine open to prevent that fiber web from centering on the device that roller or band circulation are reeled.
Background technology
When input of width of cloth material or the disconnection of width of cloth material, width of cloth material input tape or width of cloth material can be followed the surface of roller or for example follow the surface of band in belt calender.This causes so-called coiling, and wherein, width of cloth material is around roller or around tape wrapping.Can produce dangerous situation at this.
Summary of the invention
The objective of the invention is to, a kind of technical scheme of fairly simple and dependable performance is provided, can prevent this coiling thus.In order to realize this purpose, apparatus according to the invention be characterized in that, this device has at least one doctor-like cutter along the horizontal expansion of roller or band circulation, this cutter when fiber web normally moves and the surface isolation of roller or band ground be provided with and have a plurality of parts, with by rapid movement channeling conduct, prevent the coiling of fiber web with respect to the surface of roller or band.
Description of drawings
Below present invention will be described in detail with reference to the accompanying, wherein,
Fig. 1 shows schematic side elevation according to the embodiment of device of the present invention in conjunction with roller.
The specific embodiment
Fig. 1 shows, and advances forward from roller 6 at the fiber web W normal in service of fiber web.Replacing roller also can be the band circulation, for example metal tape circulation.Device according to the present invention is arranged on the supporting member 4 of the cutter on the support 1 that is connected with supporting structure, is combined with cutter keeper 7 on this supporting member.Actual cutter 5 is fixed on this cutter keeper, thereby can rotate around this cutter keeper.The cutter keeper rotates about supporting member 4 by means of the pressure hose 2 of load-side and the variation of replying the pressure differential between the pressure hose 3 of position side (Rueckstellungsseite).Be in operation, the pressure in two flexible pipes connect and cutter 5 by the surface isolation of prevailing pressure in flexible pipe and roller 6.The setting outwardly of the contiguous as far as possible roller of cutter 5.Situation about disconnecting for example for width of cloth material, two ends at pressure hose 3 are provided with fast decompression valve (Schnellabbauventil) in the answer position side, this fast decompression valve is used for reducing according to the width of cloth material cut-off signal pressure of flexible pipe 3, and the pressure in this load flexible pipe 2 makes cutter 5 by rotating with respect to the rapid movement on the surface of roller 6 and preventing that thus the width of cloth material W from reeling around roller.Cutter can be regulated by the normal operation period prevailing pressure in load flexible pipe 2 at width of cloth material with respect to the load pressure on roller surface, and is adjusted during cutter and surface isolation.Therefore the load pressure of cutter can be less than the load pressure in the conventional scraper, and it does not have fast decompression to act on functionally by corresponding pressure hose principle and the geometry and the rigidity aspect of support is not had the high requirement like that of traditional scraper.The conventional scraper that moves with the cutter of opening can not be used to prevent reel owing to its inertia when width of cloth material disconnects at all.
Cutter 5 can be only basic identical with the width of width of cloth material input tape the locational minimum setting of width of cloth material input route, and this is enough to prevent that width of cloth material input tape is around roller or around being with circulation to reel.Preferably, two or more cutters can be prolonged roller or band axially/the width each interval turns up the soil and is provided with in succession.Also a cutter can be arranged to extending on the axial length of whole roller shell or on the width of band fully basically.In according to the solution of the present invention, cutter needn't be arranged to vibrate, because cutter only is arranged on the surface of roller or band when input of width of cloth material or the disconnection of width of cloth material regularly.

Claims (5)

  1. One kind be used for when width of cloth material input or width of cloth material disconnect will the pending fiber web (W) of paper machine/toilet paper machine/board machine or post-processor from be in machine roller (6) thus surface or the surface that is in the band circulation in the machine be directed away the device that prevents that described fiber web from reeling around roller or band circulation, it is characterized in that, this device has at least one cutter (5) along the doctor-like of the horizontal expansion of described roller or the circulation of described band, this cutter is provided with on described fiber web (W) and the surface isolation of described roller (6) or described band ground when normally moving and has parts (2,3), in order to by rapid movement channeling conduct, to prevent the coiling of described fiber web (W) with respect to the surface of described roller (6) or described band.
  2. 2. device as claimed in claim 1 is characterized in that, described cutter (5) extends on the width of the width of cloth material input tape of described fiber web at least.
  3. 3. device as claimed in claim 2 is characterized in that, described cutter (5) extends on the length of described band or whole described roller (6) vertically basically.
  4. 4. device as claimed in claim 2 is characterized in that, with axial spacing a plurality of cutters (5) is set one after the other along axially going up of described roller (6) or described band.
  5. 5. each described device in the claim as described above, it is characterized in that, the parts that cause described rapid movement of the pressure hose of load-side (2) are corresponding with the parts that cause described rapid movement of the pressure hose (3) of replying position side, these parts act on the pressure hose when the normal operation of fiber web, and described pressure hose (3) is configured with the quick pressure releasing valve at the two ends of described flexible pipe.
