Definitions

  • the present invention relates to a device for sequentially starting and stopping separate groups of operating means in adjustable time intervals as for example, in the starting and stopping the operation of textile machines, particularly open end spinning machines, in which mass piecing is performed by reversing the run of the withdrawing and winding means by an electrical control mechanism provided with switch elements each of which is operatively associated with a respective group of spinning units and each of which is adjustable to determine the time of operation of its respective group of operating elements for such spinning units.
  • a device for controlling this process of socalled mass piecing; this device consists of a combination of time and switching relays which cooperate with electromagnetic brains and clutches.
  • the disadvantage of those elements used for the said process consists in their dependence on the accuracy of their adjustment;
  • a so-called stop relay in said device responds thereto, said relay due to voltage loss, interrupting its connection with the power supply network and thus starting the course of operations for stopping the machine in the proper time sequence.
  • the operating elements for performing this sequence of operations are supplied by the necessary power from an auxiliary source of power, which in the described apparatus is formed by capacitors.
  • said auxiliary power source is constituted by a rotating electric machine, e.g., an AC-generator or a DC generator, using the run-out of the working machine as such and being connected to an electric circuit in which there are further connected two control devices for the direct control of the separate mechanisms of the spinning units.
  • the main disadvantage of the above-mentioned device in which the control of the mass piecing is performed by adjustable switches controlled by a rotating finger or dog driven from the main motor of the machine, is that a certain percentage of accuracy is achieved which, however, cannot overcome the difficulties in mass piecing due to the limited extent of the adjustability of the device, which is determined by the arrangement of the switches and the dimension of the disc on which said switches are arranged.
  • This limited accuracy of the device results in inaccuracies in inducing impulses for the separate control mechanisms, such inaccuracies disturbing the continuity of the mass piecing process.
  • the device according to the present invention has among its objects substantially to mitigate the mentioned disadvantages of the devices hitherto known by making possible a simple and accurate adjustment of the time intervals necessary for starting and stopping the separate groups of operating means of the open end spinning machine in a time sequence which is necessary for stopping and restarting of the spinning process in this machine.
  • each of the switch elements has at least one control element the motion of which is derived from one of the common elements of the machine via a clutch.
  • One advantage of the device according to the present invention is that it is possible to eliminate both electrical and mechanical assemblies which previously caused failures upon mass piecing; another advantage, of the device according to the present invention is that it makes possible an accurate and easy adjustment, i.e., a programming of all operations, particularly their sequence in accurate time intervals, whereby an accurate and fast yarn piecing is achieved with the elimination of time losses, the use of said device results in the higher quality of the final product, i.e., the yarn and the simultaneous increase of the productivity of the spinning machine.
  • FIG. 1 is a perspective view of the arrangement of the common parts of an open end spinning machine together with the device according to the present invention:
  • FIG. 2 is a detailed section of the device according to the present invention in side view.
  • FIG. 3 is a detailed view in front elevation of the device according to the present invention.
  • FIG. 1 there is shown an open end spinning machine which is provided with a plurality of spinning units 1 (one shown) arranged in a row on one or. both sides of the machine.
  • the machine is equipped with common driven elements 2, 3, 4, e.g. in form of cylinders or shafts, of which element 2 performs the feeding of fiber 5 into the spinning units 1, element 3 performs the withdrawal of yarn 6 fromthe spinning units 1 and element 4 performs the winding of said yarn 6 onto bobbin 6.
  • the said driven elements 2, 3, 4 are ar ranged along the whole length of the machine and end at side wall 12 of the machine in means of transmitting rotary motion to them from the main driving source of the machine, i.e., from an electric motor 9 mounted in the lower part of the machine.
  • the main driving source of the machine i.e., from an electric motor 9 mounted in the lower part of the machine.
  • the control device 11 FIGS. 2 and 3 has a circular body 13, in the center of which there is mounted an electromagnetic clutch having two parts 141, 142, formed by clutch wheels, which are provided with confronting selectively meshing gearteeth 151, 152, respectively.
