Definitions

  • the rod-shaped body need not necessarily have by itself a conical shape, nor has it to be necessarily hollow, but it only must be provided with ends having different diameter, or thickness.
  • Devices are known from the prior art, which draw the tubes one by one from the storage container, and deliver them to the vertically positioning device.
  • This latter orients the same tube in the correct direction, conveys it, by gravity, to a feed channel, or the like, for centering it relatively to the support pin - or a similar element - provided on the conveyor belt.
  • the device is known, which is disclosed and claimed in Italian Patent No. 20,763 A/68, files by the present Applicant, which is characterized in that its orienting and vertically positioning elements are stationary, rather than movable.
  • the sensors responding to the orientation of the tube are longitudinal slits provided on plates pre-arranged in a chute configuration, along which the tube slides by gravity. Said slits are calibrated with a width smaller than the largest diameter of the tube, and with a width larger than the smallest diameter of the tube.
  • the main purpose of the present invention is therefore to ensure an ordered running of the whole step of loading of the tubes on the pins of the conveyor means, such that defects and disadvantages typical of the present arrangements as proposed by the prior art, together with those as hereinabove listed, may be overcome.
  • a further purpose of the present invention is to provide a device having a simple structural shape, and which is so shaped that the process of tube vertically positioning and orientation can be carried out quickly and with no troubles.
  • the present invention for the ring spinning frames, it is anyway understood that what is said for said ring spinning frames applies also to any textile machines wherein for the automatic loading a tube vertically positioning and orienting device is required, in that on the device those differences which characterize the various types of said textile machines, do not have any influence.
  • the device of the present invention does not alter in any way the operating system and the pieces of equipment concerning the spinning spindles, so that the traditional ring spinning machine is not described, but reference is only made to those parts thereof which concern, and clarify the usage of the present invention, and, precisely, only the conveyor means serving to bear the pins which serve to support the empty tubes; the drawing device, suitable for drawing one tube at a time from the storage container wherein it is stored parallelly to other tubes; and the conveyor means which supply the individual tube to the operative area wherein the orientation takes place, will be referred to.
  • said means which all are already known from the prior art, are not shown in the figures, because they are not essential for understanding the orienting and vertically positioning device of the presnet invention
  • the present invention relates to a device furthermore characterized in that the re-positioning of the angle support plates, by means of the return stroke of the stems, takes place by starting at different time points, due to a delay in the enabling of the actuator corresponding to the angle support housing the smallest diameter of the rod-shaped conical tube.
  • the present invention relates to a device wherein the contact sensors are reduced to one single contact sensor, or similar element, only, enabled each time that opposite to it the smallest-diemeter end of the rod-shaped conical tube is present.
  • the present invention relates to a device wherein the stationary tube-stop plate can be adjusted, in its frontal position, relatively to the contact sensors.
  • the loading unit When the pin-bearing conveyor belt running along the operating front of the spinning frame, of a proper structural type, and known from the prior art, requests empty tubes 12, the loading unit is enabled, which draws said tubes 12 from a container, of a type known from the prior art, in order to transfer them, one by one, into trays, or similar housings, belonging to a lifting and conveyor means, known from the prior art, and therefore not herein disclosed.
  • Said lifting means delivers, by a stepwise indexing, the individual tube 12, in a perfectly frontal position, to the angle-profile plates 10 fastened onto the ends of the stems 26.
  • the drive sources 2 are simultaneously enabled, e.g., by means of actuator means 28, said drive sources 2 driving the stems 26 integral with the corresponding angle-profile plates 10, to move.
  • the angle-profile plates 10 move frontally towards the rod-shaped conical tube 12, draw it from its housing, and translate it, supporting it, towards the stationary stop plate 14.
  • the angle-profile plates 10 advance in perfect synchronism and operate, during said motion step, as if they were one single, rigid, mobile transfer saddle.
  • the arrows 24 indicate the trajectory and direction of advancement during said movement for tube 12 translation (see Figure 2).
  • the rod-shaped conical tube 12 is pushed against the stationary stop plate 14.
  • the sensor 16 is enabled (see Figure 2), by the contact pressure applied by the front thickness of the angle-­profile plate 10, which supports the tube 12 portion close to the smallest-diameter end.
  • the enabling of the sensor 16 causes the inhibition of the advancement of the stems 26 by the drive sources, or actuators 2. It derives therefrom that the pushing of the tube against the front surface of the stationary stop plat 14, by the angle-profile plates 10, ends, preventing any possible jammings of the tube 12 between the above-aid elements from occurring, and leaving the tube 12 free to perform the following step of rotation, necessary for it to be posed in the vertical position.
  • both the angle support plates 10 result to have reached their initial configuration, waiting for the subsequent operative cycle, enabled by the request for another rod-­shaped conical tube 12, to be repeated.
