Definitions

  • the invention relates to a run-on device for jobs of double-twisting and cabling machines according to the preamble of claim 1.
  • Textile machines designed as double-wire twisting and cabling machines usually have a multiplicity of workstations, each of which comprises a twisting spindle or cabling spindle area and a casserole area.
  • the jobs are arranged side by side in the machine longitudinal direction.
  • the processing of the yarn takes place in the twisting spindle or cabling spindle area.
  • the threads are given the necessary rotation there.
  • the twisted yarn is wound in the casserole area to a cross-wound bobbin.
  • U1 is a double-twisting machine known, are arranged in the usual way in each case identically constructed jobs on opposite machine outer sides in order to achieve a high space utilization of the textile machine.
  • the finished packages are transferred by means of a transfer device from the creel to a running in the middle of the machine conveyor belt.
  • the creel carrying the cheese is connected to a support arm.
  • the pivot axis of the support arm is arranged in the region below the conveyor belt.
  • a low overall height of the machine should be achieved in order to arrange the supply device for supply bobbins above the twisting machine in relatively low and still easily accessible height. Due to the arrangement of support arm and creel in the area between the winding cylinder and the vertical longitudinal center plane of the machine is to be achieved free access to thread-leading parts.
  • the DE 42 17 360 C2 describes a twisting machine in which a plurality of twisting spindle field are arranged on a spindle bank in the usual way.
  • the twisting spindles designed as cabling spindles have a spool pot which encloses a first yarn spool.
  • a second yarn package is arranged outside the bobbin. The formed twist is fed via a deflection roller of the winding device.
  • the casserole area of these textile machines consists of a leading roller assigned to the workstation for stress relief of the thread, an iridescent thread laying to form the cross-wound bobbin, a winding roller for driving the sleeve or bobbin and a creel supporting the sleeve or cross-wound bobbin.
  • Both advance role and winding roller of the known overrunning devices are each driven by means of continuous waves.
  • the waves pass through the entire textile machine on both sides of the machine in the machine longitudinal direction.
  • the drive of each shaft is made by a drive device at the head of the machine.
  • the continuous waves are, as for example for the shaft of the advance rollers in the DE 100 459 09 A1 shown is often equipped with covers.
  • the covers are intended to prevent accidents and reduce the pollution of the shaft bearings.
  • the upper, the operator facing space of the double wire or cabling machine is filled by continuous waves or covers. This hinders free access to the casserole.
  • the spindle bank which carries the twisting or Kablierspindel, lowered down. This allows ergonomic operation. A change in the spindle bank position is also made, for example, if more space is required because two bobbins are used to save the technical process.
  • the overfeed roller is mounted in each case on a support element and can be pivoted together with the support element about a pivot axis optionally into an operating position and into an operating position, the operating clearance for the spindle can be increased so much by the pivoting of the support element that a uniform size of the textile machine for different large templates can be used.
  • the resulting by the pivoting of the support element space allows unimpeded operation in the operating position, even if the spindle bank is not lowered as in known machine designs.
  • the operating height of the textile machine does not need to exceed a value of 1300 mm to provide a sufficient operating clearance. This fulfills the usual requirements with regard to ergonomics.
  • a continuous separate shaft for the Voreilrolle including associated shaft bearings and drive is eliminated.
  • the cover extending in the case of conventional overrun devices along the continuous drive shaft of the overrunning rollers, which serves to protect the shaft bearings and is necessary for accident prevention on the continuous, continuously rotating drive shaft is unnecessary. Due to the omission of the continuous shaft for the advance rolls, an additional free space laterally of the advance rolls, which allows better accessibility of the creel frame and thus an ergonomically improved operability, is created in the area of the run-up device.
  • An overrun device whose friction roller is fixed on the drive shaft and whose advance rollers is driven by means of a transmission element of the drive shaft and wherein the drive shaft forms the pivot axis of the support element, provides a particularly simple and cost-effective Execution is, which also allows a compact, space-saving design.
  • a trained as a round belt transmission element is associated with low cost and allows safe operation. Due to its surface condition in connection with a pre-selected Auflegespannnung the drive can act by means of round belts as a slip clutch. This increases the accident safety of the leading role.
  • the support element comprises a direction of the package winding attachment, by which the package is lifted in the operating position of the drive roller.
  • the attachment of the support element bears against the surface of the overrun roller and takes it along in the further course of the pivoting movement.
  • the take-up roller lifts off the friction roller.
  • the runner automatically goes dead, and the rotation of the runner is stopped.
  • the pivoting of the support element by means of a lifting cylinder is easy and quick to carry out.
  • the pivotal movement of the support element is particularly fast, safe and trouble-free possible.
  • existing in the textile machine compressed air supply can be used.
  • a thread monitor which is arranged in the yarn path in front of the advance roller and a signal for pivoting the Carrying element generated when no more thread is detected, can be triggered automatically at the respective work site, the pivoting operation in the operating position.
  • the maintenance work can be started immediately without hindrance.
  • the casserole device according to the invention not only allows a standardization of the types of double-twisting and cabling machines with different templates in the spindle area. Even activities such as threading, cleaning and removal of windings in the area of the advance roll are considerably simplified. Likewise, improved accessibility of the Fadenumlenkrolle and a simplified replacement and replacement or change of the Voreilcons is possible.
  • the operation of the workplace is safer and improved accident prevention on the double-twisting and cabling machines.
