Definitions

  • the invention relates to an apron drafting system, in particular a double apron drafting system according to the preamble of claim 1 and a spinning machine, in particular a ring spinning machine or a flyer, with such drafting systems.
  • Such drafting devices are normally assigned special sliver stop devices which, for example, interrupt the sliver transport in the event of a winding risk or in the event of a winding forming, in particular in the area of the delivery rollers or, for example, if the thread breaks.
  • the load arm having the pressure rollers is then pivoted upward, so that the rollers underneath are freely accessible and can be cleaned.
  • the fuse must then be drawn back into the drafting system again and again, which is relatively cumbersome and time-consuming.
  • a drafting system for a spinning machine in which the strapped loop cage lower roller for frictional engagement rests on the associated drive cylinder and, when the loading arm is closed, is pressed against the drive roller by the overlying, strapped loop cage pressure roller.
  • the cage lower roller or the pair of cage lower rollers is mounted on a guide link which can be pivoted about a guide rod parallel to the drive cylinders.
  • the aim of the invention is to provide a drafting system of the type mentioned in the introduction, in which a respective sliver stop can be brought about quickly and easily to eliminate coils, thread breaks or the like, and in which the sliver is also drawn into the drafting unit after such a sliver stop and is thus ready to start remains.
  • the pressure force is seen in front of and behind the strap-wrapped cage pressure roller arranged pressure rollers in particular is provided directly by a force-displacement generating device acting on the loading arm, it is particularly advantageous if the pressing force of the pair of straps is carried out independently by means of a spring, the reaction force of which, however, is also provided by the force-displacement generating device is recorded.
  • the cage pressure roller and the associated cage lower roller can be mounted together on a pivoting lever which extends in the longitudinal direction of the loading arm and which is resiliently biased towards the relevant drive cylinder and whose pivoting movement towards the drive cylinder is limited.
  • the cage pressure roller and the associated cage bottom roller can be held resiliently against one another.
  • the cage pressure roller and the associated cage bottom roller are expediently mounted on a common carrier fastened to the loading arm.
  • the embodiment according to claim 6 has the advantage that, in particular in the case of a spinning machine with a large number of drafting systems lying next to one another, each individual load arm and the pressure rollers arranged thereon can be brought into engagement with the drive cylinders with defined pressure, or the pressure rollers can be lifted off the drive cylinders are. Since all force-displacement generating devices are acted upon in parallel from the central power source, the force exerted by the load arms on the individual drafting systems can be set centrally to a predetermined value. Furthermore, all of the load arms can be relieved of the closing force simultaneously and jointly by the central control of the power source, if this is expedient, for example, in the event of operational interruptions. Nevertheless, an individual relief of individual load arms and thus an individual triggering of a match stop can be carried out in a simple manner.
  • the embodiment according to claim 7 has the advantage that despite the limitation of the transmitted clamping forces, the intervention in the drafting system is hampered as little as possible from the operator side.
  • a further, particularly advantageous practical embodiment is characterized by claim 8, wherein the stop can in principle also be provided on the loading arm and the hook on the mechanical tension member or the rod.
  • the stop can be disengaged from the hook by turning the rod head, so that the loading arm is then pivoted further upward can be.
  • the particularly advantageous development according to claim 10 ensures a constant force transmission ratio between the first and third pressure roller when the loading arm is pulled up by means of the force-displacement generating device via the mechanical tension member.
  • the power transmission ratio is of the order of 1: 1 and is preferably changed in a ring spinning machine in such a way that the power transmission at the outlet pressure roller is somewhat higher than at the inlet pressure roller, while with a flyer the conditions are just the opposite.
  • the rocker arm and the pivot lever can be attached to a common carrier, which is preferably detachably attached to a pressure roller support arm of the loading arm.
  • a common carrier which is preferably detachably attached to a pressure roller support arm of the loading arm.
  • the force-displacement generating device only has to act in the clamping direction, while when it is relieved, the opening spring ensures the opening of the loading arm at least to the extent that the pair of straps is no longer driven by the associated drive roller and accordingly there is a sliver stop.
  • the force-displacement generating device can be double-acting and accomplish both the closing or clamping process and the opening process of the loading arm to bring about the match stop.
  • a pneumatic reversing valve would have to be provided to act on the piston-cylinder arrangement.
  • the embodiment acting on one side in the clamping direction according to claim 15 is possible.
  • the stroke of the force-displacement generating device is preferably limited to the extent evident from claim 16, while the further movement of the loading arm and the base frame is to take place by hand after the tension member has been unhooked.
  • Claim 17 defines a particularly advantageous circuit for the pressure or force application of the individual drafting systems from a central force or pressure source.
  • the respective degree of automation of the spinning machine in question can be increased in an advantageous manner in that, according to claim 18, means are provided for detecting an occurring winding risk or the beginning of winding formation, a thread break etc. and the swiveling-up movement of the loading arm can be triggered automatically as a function thereof.
  • the pivoting movement of the loading arm can preferably take place via the force control device.
  • Manual control of the force-path generating device via the force control device can take place, for example, via an actuating button arranged on the base frame of the spinning machine.
  • This training is particularly advantageous for a flyer.
  • the fact that the operating button the load arm does not contain any cables in the form of electrical cables and pneumatic tubes. It can thus be removed and re-installed without removing or removing such lines.
  • the hook is advantageously provided with a run-on slope for the power transmission stop, which is preferably designed as a locking bracket.
  • the invention further relates to a spinning machine, in particular a ring spinning machine or flyer, having a multiplicity of apron or double apron drafting devices of the type mentioned, in which continuous drive cylinders, each associated with a plurality of drafting devices, are provided.
  • a further pair of drive cylinders and pressure rollers can be provided in the direction of the roving, the drive cylinder being arranged in the base frame of the flyer and the further discharge pressure roller on a spring-loaded, further pivot lever mounted on the load arm or pressure roller support arm or carrier.
