Definitions

  • the present invention relates to a Goods take-off roller arrangement, in particular for Flat knitting machines, according to the preamble of claim 1.
  • the object of the present invention is therefore a Goods take-off roller arrangement, in particular for Flat knitting machines, of the type mentioned at the beginning create that improved, less expensive articulated to manufacture and easier to assemble Torque transmission connection between neighboring Roll elements of the relevant goods take-off roller creates.
  • the measures according to the invention are considerable Simplification in the manufacture of the articulated Torque transmission means of two neighboring Roller elements achieved because both the ring gear of the Gear arrangement as well as that of the roller elements in is easier to manufacture. Furthermore, the Assembly of the individual in a row Roller elements simplified in that each time only the sprockets of roller element and gear assembly in must be inserted into each other in the axial direction.
  • a firm connection that withstands operation the two gears of a gear arrangement can according to the Features according to claim 5 are realized. It is it, as realized on the basis of the features of claim 4, expedient, the two gears simultaneously with one To connect part of the radial roller bearing in a rotationally fixed manner.
  • this one has Flat knitting machine shown detached Goods take-off roller arrangement 10 a goods take-off roller 11 and a parallel counter roller 12, the circumferential practical abut each other and only one between them in Figure 3 schematically illustrated web 13 in the form of a Knitted fabric pulled through from top to bottom or from the Flat knitting machine is pulled off.
  • the Goods take-off roller 11 and the counter roller 12 against each other motor-driven according to arrows A and B.
  • a such goods take-off roller arrangement 10 is in particular suitable for so-called comb machines.
  • the pivotable on the tube 18 in the direction of the double arrow C. held support beam 17 is in accordance with Figures 1 and 5 Essentially plate-shaped and extends over substantially the entire gap area 19 of the in Distance opposite ends 21 and 22nd adjacent roller elements 16, being from the tube 18 protrudes opposite end of the gap region 19.
  • Figure 2 has the support bracket 17 in the area of Interior of the hollow cylindrical roller elements 16 a circular recess through an axial widened ring collar 26 is limited.
  • the outer ring 27 is one Radial roller bearing 28 is added, the inner ring 29th between the two gears 23 and 24 of the gear assembly 15 is held in a rotationally locking manner.
  • the support beam 17 is with its bearing shell 31 held on tube 18, to both Sides of the bearing shell 31 with ring recesses 32 and 33 is provided, introduced into the locking washers 34 are so that the support beam 17 on the tube 18 in axial Direction is fixed.
  • These ring punctures 32 and 33 are in certain distances arranged in pairs on the tube 18, so that the position of the support beams 17 is predetermined.
  • the identically designed gears 23 and 24 each A gear arrangement 15 are according to FIGS. 6 and 7 provided with an external ring gear 36, the teeth 37 transversely are curved to the circumference and crowned in the longitudinal cross section.
  • the outer ring gear 36 of each gear 23, 24 meshes with one Internal ring gear 38 of the hollow roller element in question 16.
  • the inner toothed ring 38 provided with straight teeth of the roller element 16 is in one end in alignment with the relevant end 21, 22 of the roller element 16.
  • the width the inner ring gear 38 is slightly larger than that of Outer ring gear 36 of the gear 23 or 24.
  • the gear 23, 24 has according to Figure 6 on one side a coaxial hub 41, which has a positive-locking profile on the end face 42, the projecting profile elements 43 the same Geometry like the recessed profile elements 44 exhibit.
  • This geometry makes it possible to have two gears 23, 24 positively by means of the profile 42 and thus to connect in a rotationally interlocking manner, like this also emerges from Figure 2.
  • Two adjacent gears 23 and 24 are made using a connection from screw 46 and nut 47 axially through the hub 41 held together.
  • the nut connection 46, 47 is tightened such that the two gears 23 and 24 axially against each other and thereby the inner ring 29 of the radial roller bearing 28 between them frictionally jam. Because the hubs of the gears 23, 24 on the circumference the inner ring of the roller bearing 28 may be limited the elastic deformation of the plastic material by the Force of the screw connection only in the area of the claw connection impact and thus ensures that these are free of play is.
  • the assembly of the roller elements 16 and the Gear assemblies 15 existing goods take-off roller 11 goes as follows: First, the pre-assembly takes place the gear assembly 15 each made of two gears 23 and 24 on the support bracket 17 provided with the radial roller bearing 28. There is a first support beam 17 via the tube 18th pushed and by means of the locking washers 34 on the provided the outermost position of the ring recesses 32 and 33 fixed with lock washers 34. After that, a Roller element 16 with its one end 22 on the gear 23 of the first support bracket 27, so that the External toothing 36 engages in the internal toothing 38 is coming. Then the next preassembled support beam 17th pushed onto the pipe 18 until the previous roller element 16 facing gear 24 this engages.
  • the rigid tube 18 is accurate over the imaginary longitudinal axis of the goods take-off roller 11 arranged and the two rollers 11 and 12 are in one horizontal plane.
  • a stationary needle bed support or machine stand 51 At the counter-roller 12 facing away Circumferential area of the goods take-off roller 11 is below the horizontal center plane of the two rollers 11 and 12 a stationary needle bed support or machine stand 51 a clamping device 52 for each roller element 16 attached, which serves the goods take-off roller 11 each in the roller element connection area against the to press rigid counter-roller 12 resiliently.
  • the Clamping device 52 is stationary with its housing 56 a middle rail 57 held on the machine stand or the like is kept stationary.
  • Screw spindle 53 whose by a knob 58 in the axial Movable inner end via a compression spring 54 presses on an axially movable pressure piece 59.
  • the power the compression spring 54 is on the pressure piece 59 on a Cams 61 of the support beam 17 brought in this way two adjacent roller elements 16 of the take-off roller 11 against the counter roller 12 presses.
  • the screw spindle 53 is in their inner area with a cruciform here Display element 62 fixedly connected, with its here cross-shaped wings each in one Housing slot 63 is guided.
  • On circulating Scaling rings 64 can be the path of the screw movement and thus the pressure applied to the Support bracket 17 can be read.
  • Knitwear specific contact pressure can be with a further production at a later point in time can be set using the scaling.
  • the support beam 17 also has a nose 66 above the cam 61 which a region of the angle rail 57 faces and the Swivel path of the support bracket 17 limited when the Contact pressure is applied to the cam 61 and the counter roller 12 is pivoted away.
  • the support bracket 17th On the nose facing away from the nose 66 and thus the counter roller 12 facing side of the cam 61 has the support bracket 17th a protrusion 67 which, as a deflecting surface, prevents a knitted piece wraps around the take-off roller 11 when it by electrostatic charging on the take-off roller 11 should stick. Furthermore, the support bracket 17 has one Cover web 68, which is opposite to the thickness of the support beam 17th is relatively wide and on the narrow peripheral edge 69 of the Support beam 17 rests in an area and held firmly is, as can be seen from Figure 3, approximately from the vertical longitudinal center plane in the direction of the counter roller 12 towards the gap 19 between two adjacent roller elements 16 runs. So that the gap 19 between adjacent Roller elements 16 covered so that no loose Knitting threads can be wound up.
