Definitions

  • the invention relates to a goods withdrawal device for a weaving machine, in particular wide weaving machine, with a driven fabric take-off roller that is transverse to it Axial direction is arranged movably, each with one of the Fabric take-off roller upstream and downstream Deflection element, which are rotatably supported, the clear distance between the deflection elements is smaller than the diameter of the fabric take-off roller as well as with a Pressing device with an essentially over extending the length of the fabric take-off roller Press component.
  • Such a goods withdrawal device is from the EP-A-0 224 850 is known.
  • This device contains one pneumatic device with a pressure hose, the is arranged below the pressing part and with Compressed air can be applied to the fabric take-off roller to press against the deflection elements.
  • the invention is based on the object Goods removal device of the type mentioned at the beginning improve.
  • the advantages of the invention are essentially simple structure and in ensuring the Contact pressure can be seen in the operating position.
  • the pressing device is a Has a plurality of actuating device, so that due the multiple support of the diameter of the take-off roller and the length X of the goods table can be reduced can.
  • a weaving machine with such a device is according to the invention by the features of claim 8 characterized.
  • FIG. 1 shows a section of a weaving machine a goods take-off device 1 and a Goods winding device 2, which with a full merchandise tree 5 is loaded. From this figure is the Course of the fabric 3 from the stop edge 4 to Tree 5 can be seen.
  • the goods withdrawal device is arranged in end shields 6.
  • the end shields are in equal distances on the frame 7 of the weaving machine attached, the number of end shields from the Weaving width is dependent.
  • the dimension "X" indicates the Length of the so-called goods table.
  • the pressing device 13 contains a pressing part 16, which is essentially the length of the Fabric take-off roller extends (Fig.4) and at least one Actuator 17 to the fabric take-off roller in a Shift operational position so that Fabric take-off roller 11 with the interposition of the fabric 3 the guide rollers 12 abuts.
  • the actuating device 17 is mounted on the end shield 6 and comprises an arrangement 18, which can be moved in a recess 23 in the bearing plate 6 is arranged and on which the pressing part 16 is rotatable is arranged.
  • the arrangement 18 contains a holder 21, a support part 22 which is resiliently supported in the holder 21 is a toggle lever 24 which on the one hand is connected to the holder 21 and on the other hand articulated to the bearing plate 6 is a rack 25 which is connected to the joint 26 of the Knee lever is connected and a fixed stop e.g. a bolt 27.
  • the rack 25 is with a gear 28 engaged, the component of a drive device is.
  • the support part 22 is on one Supported spring 30 and it is a means 31 for Adjustment of the spring force provided. To change The spring force can also be exchanged or the number of springs used can be changed.
  • the winder shown in Fig.1 has two backup rollers 41 and an intermediate roller 42, the each coupled to a drive, not shown are as well as a first deflecting roller 43, which on a in the plane of the fabric descending is and a second guide roller 44, which on the Fabric web lies freely and through the fabric tension with the Back-up roller 41 and the intermediate roller 42 comes to rest and which with yielding tissue tension on a Support shell 45 rests.
  • Goods take-up device is during operation of the Loom maintain the tension in the fabric and also a change of the merchandise tree without stopping the Weaving machine.
  • the first guide roller 43 due to the tension exerted by the fabric with the interposition of the Fabric pulled against the driven intermediate roller 42.
  • the required fabric tension is determined using a suitable control of the speed of the Fabric take-off roller 11 and the intermediate roller 42 generated.
  • the second deflection roller 44 is by means of the looping fabric against the intermediate roller 42 and a backup roller 41 is pressed.
  • This arrangement thus enables the take-up side Cutting the fabric and taking away the goods tree without stopping the loom.
  • the finished fabric can also be carried away loosely if necessary and during the winding of an empty winding core no business interruption.
  • the goods take-off device comprises a driven one Fabric take-off roller 11, two deflecting elements 12, which are rotatable are supported, the clear distance between the Deflection elements is smaller than the diameter of the Fabric take-off roller and a pressing device 13 with one essentially over the length of the Tissue take-off roller extending pressing part 16.
  • Die Pressing device 13 has at least one Actuating device 17 with a toggle lever 24 and a Fixed stop 27 on to the fabric take-off roller 11 to shift from a rest position into a working position and set in the latter.
