Definitions

  • the present invention relates to a rotary stripping roller for a textile machine for stripping adhering to a conveyor belt of the textile machine fabric blanks.
  • the problem of adhering fabric blanks or garments on a conveyor belt is known.
  • a stripping roller for a finishing machine described.
  • the stripping roller has spaced apart dressing rings with a bristle trim and is located at the exit of the finishing machine. Between the Besatzringen a deflector rake is arranged.
  • the bristle lining of the stripper roller dissolves the fabric blanks from the conveyor belt, through the deflector rake the dissolved fabric pieces are dropped down.
  • stationary scrapers for cleaning rollers in textile machines are well known and, for example, in the EP 437 823 A1 described. These scrapers serve to strip textile fibers or the like from the rollers and are firmly attached to the machine frame.
  • the stationary scrapers have a wiper lip which is constantly in contact with the roller and therefore is not subjected to dynamic loads or shock loads.
  • the invention provides that the stripping roller has an elongated roller base body with at least one releasably attached to the roller body scraper lip.
  • the roller body must be rotatable, but can have any cross-section.
  • the roll main body in cross section e.g. be square or circular.
  • the axis of rotation coincides with the longitudinal axis of the roller body.
  • the at least one wiper lip is releasably secured to the roller body, only the wiper lip of the wiper roller must be replaced when worn, the most expensive roller body can be used.
  • the roller base body has at least one undercut running in the longitudinal direction, in which a thickened foot region of the wiper lip is arranged.
  • the stripping roller is thus formed in the manner of a welt, wherein the undercut in the roller base body forms the piping rail into which the thickened foot region of the stripping lip designed as a piping is inserted.
  • the at least one undercut in the roller base body is formed by a substantially T-shaped groove.
  • the groove has a T-shaped cross section, wherein the crossbar of the Ts is formed in the roll main body and the center bar of the Ts opens to the outside.
  • This groove can be easily manufactured and allows easy insertion of the wiper lip in the roller body.
  • the foot of the wiper lip is formed complementary to the groove and therefore also T-shaped.
  • the at least one wiper lip extends radially outward with respect to the axis of rotation of the roll main body. This achieves a good wiping action of the wiper roller, the grooves can be easily manufactured and the wiper lip can be easily inserted into the groove.
  • a plurality of wiper lips are detachably fastened to the roller base body.
  • each undercut extends parallel to the axis of rotation of the roller body and each wiper lip is mounted parallel to the axis of rotation of the roller body to the roller body.
  • each wiper lip is mounted parallel to the axis of rotation of the roller body to the roller body.
  • each undercut extends helically in the roll main body and each wiper lip is helically attached to the roll main body. This helical shape achieves an improved wiping action of the wiper roller.
  • the roller main body is a metal profile.
  • This may have any cross-section and, for example, circular or polygonal, e.g. be rectangular or square.
  • the roll base body is then easy to produce, for example by an extrusion process such as extrusion.
  • the at least one wiper lip is preferably made of an elastomer, for example silicone. This allows a good and gentle stripping of the fabric blanks from the conveyor belt. Since in a fuser often sensitive fabrics are connected to a reinforcing fabric, a gentle treatment of the fabric blanks is particularly important.
  • Fig. 1 a perspective view of a rotating scraper roller 1 is shown.
  • the scraper roller 1 comprises a roller body 2 and wiper lips 3.
  • the wiper lips 3 are detachably fastened to the roller body 2.
  • the roller base body 2 has an elongated shape and is provided on both end faces with holes 4, are introduced into the pins to allow a rotatable mounting of the roller body 2.
  • the stripping roller 1 is used in textile machines, preferably fixing machines, in order to release fabric blanks adhering to a conveyor belt of the fixing machine.
  • the stripping roller 1 is therefore preferably arranged at an output of the fixing and rotatably supported by means of the holes 4 in the Walzengrundgroper 2 and arranged in the holes 4 pins.
  • the direction of rotation of the stripping roller 1 is preferably opposite to the transport direction of the conveyor belt of the fixing machine.
  • roller body 2 has a substantially square cross-section.
  • the roller base body 2 can also have any other cross-section and be, for example, polygonal, such as triangular or rectangular, or circular. It is also conceivable that the roller base body 2 is formed by a hollow profile, which can be rotatably mounted accordingly.
  • the roller base body 2 has an undercut 5 on each of its sides.
  • the undercuts 5 extend in the longitudinal direction of the roll base body 2 and are open at least on one end face 6, preferably on both end faces 6 of the roll base body 2.
  • the undercuts 5 are formed by a groove which has a T-shaped cross-section.
  • the crossbar of the Ts is arranged in the interior of the roll base body 2, the middle line of the Ts extends outwards, so that the groove is open to the outside.
  • the groove may also have a different cross-section and be C-shaped, for example.
  • the wiper lips 3 are arranged. This is also in Fig. 2 clear to see.
  • the wiper lips 3 comprise a foot region 7 and a wiper lip 8 extending outward from the foot region 7.
  • the wiper lips 8 widen in the direction of the foot region 7.
  • the arranged on the conveyor belt tip of the wiper lips 8 has a smaller width, this can easily bend and slide along the conveyor belt.
  • the foot region 7 of each wiper lip 3 is formed complementary to the undercuts 5 in the roll main body 2.
  • the wiper lip 3 is substantially T-shaped, wherein the foot region 7 the crossbar of the Ts and the wiper lip 8 forms the center bar of the Ts. Between the wiper lip 8 and the foot portion 7, grooves 11 are provided on each side of each wiper lip 3 in the longitudinal direction. In these grooves 11 engage projections 12 of the undercuts 5 (see Fig. 2 ).
  • the connection between the roller body 2 and the wiper lips 3 takes place in the manner of a welt.
  • the wiper lips 3 are simply pulled in from one of the end faces 6 of the roller base body 2 into one of the undercuts 5.
  • the wiper lips 3 can be quickly and easily replaced and replaced when worn. This takes place in that the wiper lips 3 are pulled out of the undercuts 5 in the longitudinal direction of the roller body 2.
  • the wiper lips 3 are thus held in a form-fitting and / or frictionally engaged manner in the roll main body.
  • four wiper lips 3 are provided.
  • the undercuts 5 and correspondingly also the foot regions 7 of the wiper lips 3 can have a different shape than the illustrated form.
  • the grooves or undercuts 5 in the roller base body 2 have a circular cross-section and the foot regions 7 of the wiper lips 3 are designed to be complementary thereto and also have a circular cross-section.
  • a dovetail-shaped cross section of the undercuts 5 and the foot portions 7 of the wiper lip 3 is possible.
  • the roller base body 2 at each end face 6 each have a bore 4, by means of which he can be rotatably mounted in a textile machine. Through the holes 4 so a rotation axis 9 is set.
  • the undercuts 5 in the roller body 2 and the wiper lips 3 are formed so that the wiper lips 3 extend radially outward from the axis of rotation 9.
  • a substantially square roller base body 2 close the center axes 13 of the wiper lips 3 in the resting state of the stripper roller 1 with the side surfaces of the roller body 2 therefore approximately at a right angle.
  • the wiper lips 3 enclose a different angle with the sides of the roller base body 2.
  • the grooves or undercuts 5 extend parallel to the side surfaces of the roller base body 2. It is also conceivable, the grooves in such a way that they form an angle with the side surfaces of the roller body 2.
  • wiper lips 3 such that an angle is formed between the foot regions 7 and the wiper lips 8, which angle is preferably in the range of 30 ° to 90 °.
  • each undercut 5 in the illustrated case, ie the T-shaped grooves, preferably extend parallel to the axis of rotation 9 of the roll base body 2, so that each wiper lip 3 is fastened to the roll base 2 parallel to the axis of rotation 9 of the roll base 2.
  • each undercut 5 extends helically in the roller base body 2 and accordingly each wiper lip 3 is fastened helically to the roller base body 2.
  • the wiper lips 3 are formed from an elastomer.
  • the wiper lips 3 are made of silicone.
  • the roll main body 2 is preferably formed by a metal profile. It is then a simple production possible, for example by an extrusion process, and the roller body 2 has the required stability. But there are also other roller base body conceivable, for example, can be provided that the roller body is made of a plastic.
  • Fig. 2 is a section through the exiting from a fixing machine conveyor belt 14 which is deflected by a drive roller 15 and a guide roller 16 and driven back towards the input of the fixing machine.
  • the rotary stripper roller 1 is arranged adjacent to the drive roller 15, so that the wiper lips 8 come into contact with the conveyor belt 14 and on the Strip conveyor 14 adhering fabric blanks in the direction of a storage location. As shown by the arrows 17, 18, the direction of rotation 18 of the stripping roller 1 opposite to the direction of rotation 17 of the drive roller 15 of the conveyor belt 14. This avoids that adhering to the transport 14 fabric blanks slip through the wiper lips 3 and returned to the input of the fuser ,
  • the wiper lips 8 between the tip, which abuts the conveyor belt 14, and the transition to the foot region 7, a taper 19 have.
  • the wiper lips 8 of the stripping roller 1 first strike the conveyor belt 14 with a leading edge.
  • the wiper lips then buckle at the taper 19 to the rear, so that the edge rests on the conveyor belt 14 and strips any adhering fabric blanks.
  • a cavity 20 may be formed. Thereby, the foot portion 7 can be easily compressed during insertion of the wiper lips 3 in the undercut 5 and the insertion is facilitated.
