Definitions

  • the present invention relates to a method for stopping and positioning an equipment piece born on board of a mobile service carriage performing a continuous reciprocating patrolling motion along a side of an operating machine and furthermore to a device for practicing this method.
  • the so carried out positioning and locking unavoidably generates vibrations, of uncontrollable intensity, on the structure of the mobile carriage, with said vibrations being also transferred to the whole equipment piece on board of the same carriage.
  • Said equipment piece submitted to more or less intense vibrations will be damaged, at least in its precision members, such as, e.g., detector and position sensors, as well as operating arms and lever systems. These latter will come to operate in their movements along incorrect coordinates, in that their supports may result to be more or less deformed owing to the repeating impacts generated by the sudden stops of the mobile carriage.
  • an actuator actuates the extension of the prongs of the said fork, engaging them to surround one of a series of protruding elements rigidly fastened to the framework of the machine.
  • the fork must be associated to the presence of a tooth, or latch, capable of ensuring the carriage stopping lock during the whole time period of intervention of the equipment piece borne by said mobile carriage.
  • the structure of the fork locking means is therefore not simple.
  • the purpose of the present invention is of overcoming the above mentioned drawbacks, by providing a stopping and positioning method, by means of which the mobile carriage can be stopped at precise working positions, without considerable vibrations being generated and transmitted on the supported equipment piece borne by said mobile carriage.
  • the method of the invention is characterized by the features indicated in the characterizing part of claim 1. In order to practice this method, a device in conformity with claim 2 is used.
  • This device has a simple structure, and makes it also possible a reliable precision to be achieved over time, in that it is neither damaged nor worn during the operations; and, thanks to its structural simpleness, it is also very reliable in operation, and not sensible to dirtying effects.
  • This device is associated with means known from the prior art for the automatic monitoring and detection of the positions wherein the equipment piece supported by the saddle must perform its action, with said service carriage running along rail guides provided along the working front(s) of an operating machine, such as, e.g., a ring spinning frame.
  • the figure of the drawing table shows a top plan view of a device according to the present invention, with the sensors which are required in order to enable the mobile carriage speed reducing system; it should be observed that these sensors are not represented in their details, in that they are inside the knowledge of those skilled in the art.
  • a service carriage in order to automatically re-join the broken threads during the spinning spindles operation.
  • Said carriage is caused to run along the spinning front(s), along running ways comprising one or several rail(s) of any shapes, cooperating with suitable rolling means such as wheels, or rollers, or equivalent means.
  • suitable rolling means such as wheels, or rollers, or equivalent means.
  • the service carriage for the re-joining of the threads is continuously frontally reciprocated along the spindle bed, performing a reciprocating patrolling motion.
  • the traveling carriage detects, by using detecting means known from the prior art, whether the thread is present or not on each spinning spindle.
  • the detecting means in cooperation with the proximity sensors 1 of inductive type, as well as through the operating program, enables the actuation of an electrovalve which makes the pneumatic actuator 7 start to operate via the stem 5 and push the block 2 to its position 2a, coming into frontal interference with the protruding element 3 which comes before the space into which the same block 2 has to pushed (see the attached figure).
  • the device according to the present invention carries out an adjustable braking effect, by varying, with known means, the intensity of the frontal thrust applied by the block 2 to the protruding element 3 by means of the actuator 7.
  • the block 2 When, at the end of the front sliding, the contact begins between the inclined section 4 of block 2 and the circumferential surface of the element 3, the block 2 frontally moves to reach its position 2b.
  • a microswitch (not shown), entrusted with the task of detecting this frontal movement, disables and stops the carriage drive motor.
  • the front thrust generated by the actuator 7, the inclined section 4 of the block 2 and the circumferential surface of the element 3 make it possible, owing to the shape of their contact surfaces, the positioning block 2 to be automatically and gradually wedged into the space it must enter in order to ensure the precise alignment of the traveling equipment piece with the spinning spindle, around which the working units advance and operate.
  • the present invention proposes a method and a device suitable for positioning and stopping a mobile carriage traveling along the operating front of operating machines, without causing considerable impacts and vibrations which, should be present, would damage the equipment pieces, or equipment piece parts, carried on board by said carriage.
