Definitions

  • the invention relates to a method for inserting a cable into a stuffer box crimping device according to the preamble of claim 1 and a stuffer box crimping device according to the preamble of claim 2.
  • the crimping of synthetic fiber cables in mechanical stuffer boxes is carried out consistently at speeds of up to about 300 m / min.
  • Several bundles of threads are pulled from cans, combined into a cable and fed together to the stuffer box with a total strength of up to 4,000,000 dtex.
  • the system is started up in such a way that the cable start is placed in the roller gap at a standstill and that the speed is then increased.
  • one of the two pressure rollers is mounted on a rocker together with a pivotably mounted intermediate piece, which closes the stuffer box in the operating position, so that it moves out of the operating position can be swung out.
  • the document contains no indication that it is intended or possible to insert a continuous cable into the open stuffer box when the motors are switched on. Obviously, it is also not possible to insert a cable into the open stuffer box because the side access is blocked by machine parts.
  • the invention has for its object to provide a stuffer box crimping device of the type specified in the preamble of the independent claims for use in continuous spin drawing texturing processes, in which it is possible to insert the cable at full speed without any problems.
  • a preferred embodiment of the invention is specified in claim 3.
  • the drive arrangement according to claim 4 is particularly advantageous for the displacement of a printing roller while the machine is running.
  • the front of the machine is kept free of components that could be a hindrance when inserting the cable.
  • the feature of claim 6 largely eliminates the risk of accidents and damage to the sensitive printing roller surfaces.
  • a particularly compact design of the housing with an integrated stuffer box is specified in claim 7.
  • the stuffer box 1 is preceded by two narrow pressure rollers 2 and 2 ', the axes of which lie in a horizontal plane.
  • the pressure roller 2 is overhung on a shaft 3 in a frame which consists of a base plate 4, a gable-shaped vertical front plate 5 and a congruent back plate 5 '. It can be driven by a motor 7 via a toothed belt 6 which rotates behind the back plate 5 ' sits on top of the case.
  • the pressure roller 2 ' is overhung on a shaft 3' which is seated in a bearing bush 8. This is connected to two arms 9, 9 'and an axis 10 to form a rigid unit which is pivotable.
  • the front plate 5 and the back plate 5' are provided with a wide cutout 12.
  • the pressure roller 2 ' can be driven synchronously with the pressure roller 2 via a toothed belt 6', which also rotates behind the back plate 5 '.
  • the motors 7, 7 ' are arranged substantially symmetrically to the vertical plane 13 passing through the nip.
  • a piston-cylinder unit 14 is fastened on the one hand via a base 15 to the base plate 4 and on the other hand on an extension of the arm 9.
  • the stuffer box 1 is delimited on its four long sides by the front side plate 16, the congruent rear side plate 16 'and the two intermediate pieces 17, 17'.
  • the two side plates 16, 16 ' cover the roller gap between the printing rollers 2, 2'.
  • the edges of the plates 16, 16 'facing the pressure roller 2' run vertically.
  • Each plate is provided with a foot 18 on the opposite side.
  • the intermediate pieces 17, 17 ' have in the usual way near the nip sharp edges 20, 20', which are arranged in the manner of doctor blades with very little play to the outer surface of the pressure rollers 2, 2 '.
  • the intermediate piece 17 is adapted to the shape of the foot 18, 18 'and the side piece 17' is symmetrical for this purpose.
  • the intermediate piece 17 forms a firmly connected unit with the plates 16, 16 '. It also serves as a spacer and ensures that narrow air gaps are maintained between the side surfaces of the pressure rollers 2, 2 'on the one hand and the surfaces of the plates 16, 16' facing them.
  • Each plate 16, 16 ' has a vertical, closed at the top and down to the edges 20, 20' reaching bore 21.
  • a horizontal bore 22 opens into this, which is provided with a threaded connection for a hose.
  • the bore 21 is connected by obliquely directed channels with openings 23 and vertical grooves 24.
  • the openings 23 face the side surfaces of the printing rollers 2, 2 '.
  • the grooves 24, 24 ' bridge the narrow gaps existing between the pressure rollers 2, 2' and the intermediate pieces 17 and 17 '.
  • the unit formed from the plates 16, 16 'and the intermediate piece 17 is fastened by means of a pivot pin to a holding plate 26 provided with a base 25 and is adjustable with screws 27, 28.
  • the holding plate 26 is screwed to the front plate 5 of the housing.
  • the intermediate piece 17 ' is - without this being particularly shown in the drawing - in the same way adjustably fastened to a pivot arm 29 which can be pivoted about the axis of the pressure roller 2' by means of a bushing 30.
  • a piston-cylinder unit 31 engages, which is fastened to the arm 9 with a holder 32 which projects through the cutout 12.
  • the stuffer box 1 In the operating state, the stuffer box 1 is tightly enclosed on all four long sides by the side plates 16, 16 'and the intermediate pieces 17, 17'.
  • the lateral surfaces of the two rotating pressure rollers 2, 2 ' form a narrow gap through which the cable to be crimped is pressed into the stuffer box 1.
  • Air is blown through the bores 22, which partly passes through the openings 23 into the narrow spaces between the side plates 16, 16 'and the pressure rollers 2, 2', partly through the grooves 24, 24 'into the gap between the lateral surfaces of the pressure rollers 2, 2 'and the intermediate pieces 17, 17'.
  • the air is used to cool and prevent fibers from entering the narrow gaps.
  • the printing roller 2 ' is pivoted out of its operating position by an angle alpha.
  • the pivoting takes place about the axis of the bearings 11, 11 'by actuating the piston-cylinder unit 14 (FIG. 1 and FIG. 2).
  • the intermediate piece 17' is also shifted out of the operating position, so that the stuffer box 1 is open on the corresponding long side.
  • the pressure roller 2 ' is then brought back into the operating position, the cable is cut below the stuffer box, the intermediate piece with the piston-cylinder unit 31, which is depressurized in the ready position, pressed again, and the crimping begins.
  • the pressure rollers 2, 2 ' are mounted and driven in the same way as in the exemplary embodiment described first.
  • Each housing half 40, 40 ' has a bottom 41, 41' and a lid 42, 42 'screwed to it.
  • the bottom 42 is flanged to the front plate 5, the bottom 42 'to the bearing bush 8.
  • side plates 43, 43 'made of wear-resistant material are interchangeably inserted in the base 41 or the cover 42'.
  • Intermediate pieces 44, 44 'in the form of rings, which are cut along a chord, sit in concentric bores of the bottoms 41, 41'.
  • the cut surfaces 45, 45 'on both sides form the lateral boundaries of the compression chamber 1 below the plane of the roller axes.
  • the corresponding surfaces 46, 46' delimit an inlet channel 47 above this level.
  • the inlet channel 47 is somewhat wider than the compression chamber 1, and the stuffer box 1 is narrowed downward in a slightly wedge shape.
  • the wedge angle can be changed by slightly turning the inserts 44, 44 'in the corresponding concentric bottom recess, which forms the guide.
  • Screws 48, 48 ' which are accessible through slots in the edge of the bottom 41, 41', serve for locking.
  • the intermediate pieces 44, 44 ' are turned eccentrically on the inside.
  • On the open side there is only a very slight play between the cutting edge 49, 49 'of the insert 44 or 44' and the outer surface of the associated pressure roller 2, 2 ', which can be adjusted precisely by actuating screws 50, 50'.
  • On the other hand there is a relatively wide channel 51, 51 'on the side facing away from the nip. Additional widenings 52, 52 'are located under the axes of the pressure rollers 2, 2'. Bores 53, 53 'which can be acted upon by compressed air open into the channels 51, 51'. The compressed air can only escape in the area of the stuffer box 1 and here ensures effective cooling and prevents the penetration of fibers into the critical gaps.
  • the bottoms 41, 41' are provided with closable openings 54, 54 '. Through these openings, fiber penetration, for example, can be blown into the open.
  • the housing which is completely closed in the operating position, opens a passage 33 in the ready position according to FIGS. 5a and 6a, through which the continuous cable can be inserted into the open inlet channel, the extended roller gap and the stuffer box open on the long side.
