Definitions

  • the conical tubes for spinning frames, or for similar machines, which have their ends of different diameters must be correctly positioned and oriented on the automatic loading devices.
  • orientation it is herein meant that the tubes must all be conveyed and positioned with their axis, and their direction of conicalness, oriented according to a same direction.
  • 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.
  • a device of this kind as defined in the preamble of claim 1, is disclosed in DE-A-2 003 594.
  • the tube supporting and transferring means of this known device consist of a stationary supporting plate and of a transporting member provided with an oblong rectangular opening for freely housing a tube length, said transporting member being able to be reciprocated by means of an actuator above and along said supporting plate.
  • guiding means having lateral contact sensors.
  • the largest-diameter end of the tube comes in contact with one of said lateral contact sensors so that the tube is axially shifted in the direction of its smallest-diameter end, which comes to lay under the opposite contact sensor.
  • the tube In this shifted position and at the movement in which the tube becomes free from the lower supporting plate, the tube passes in free fall through the opening in the transporting member and its smallest-diameter end hits against one of two opposite stop members disposed at the entrance of a channel into which the tubes are to be discharged in vertical position, while its largest-diameter end rotates downwardly in such a manner that this largest-diameter end enters at first in said channel.
  • said type of solution shows the drawback that changes in the tube length and/or in the tube diameters imply the replacement of the device by another matching the different dimensions.
  • the solution is therefore rigid in its usage.
  • 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 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 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 plate 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.

  1. Vorrichtung zum korrekten Orientieren und vertikalen Positionieren von länglichen Hülsen (12), die Enden unterschiedlichen Durchmessers aufweisen, insbesondere von konischen Hülsen für Textilmaschinen, mit sattelartigen Trag- und Überführmitteln (10) zum Abstützen einer einzelnen Hülse zumindest an Abschnitten nahe ihrer entgegengesetzten Enden und zum Herausziehen dieser Hülse aus einer Schale oder aus einem ähnlichen Gehäuse, um die Hülse zu Kontaktfühlern (16, 18) überzuführen, welche die unterschiedlichen Durchmesserenden der Hülse abfühlen und es der Hülse gestatten, nur an ihrem Ende mit dem größten Durchmesser freizukommen und abstützungsfrei zu sein sowie um die Abstützung an ihrem entgegengesetzten Ende mit dem kleinsten Durchmesser zu drehen, um im freien Fall unter Schwerkraftwirkung eine vertikale Position zu erreichen, in welcher das Ende mit dem größten Durchmesser nach unten gerichtet ist, dadurch gekennzeichnet, daß die sattelartigen Trag- und Überführmittel aus zwei Winkelprofilplatten (10) bestehen, die an den Enden von Stangen (26) von zwei Stellantrieben (2) befestigt sind, welche mit gegenseitigem Abstand parallel zueinander angeordnet sind, um ihre Stangen (26) und die Winkelprofilplatten (10) in einer Richtung im wesentlichen senkrecht zur Position der Hülsen (12) in den Schalen bzw. Gehäusen anzutreiben und zu bewegen, so daß die überzuführende Hülse durch die Winkelprofilplatten (10) nur an Abschnitten nahe ihrem Ende mit dem größten bzw. kleinsten Durchmesser abgestützt ist, daß die Kontaktfühler (16, 18) relativ zu den Winkelprofilplatten (10) frontal angeordnet sind, um durch den Kontaktdruck aktiviert zu werden, der von der Plattenstirnseite aufgebracht wird, daß in einer Frontalposition relativ zu den Kontaktfühlern (16, 18) eine stationäre Hülsenanschlagplatte (14) angeordnet ist, gegen welche eine durch die Winkelprofilplatten (10) übergeführte Hülse (12) unter der Wirkung der beiden Stellantriebe (2) gedrückt wird, wobei die Hülsenanschlagplatte (14) relativ zu den Kontaktfühlern (16, 18) so positioniert ist, daß im Zeitpunkt der Berührung zwischen einer Hülse (12) und der Platte (14) oder nahe diesem Zeitpunkt nur jener Kontaktfühler aktiviert werden kann, der relativ zur Stirnseite der Winkelprofilplatte, welche die Rohrlänge nahe dem Ende mit dem kleinsten Durchmesserende abstützt frontal angeordnet ist, wogegen der andere Kontaktfühler an einer Aktivierung gehindert wird, so daß der aktivierte Kontaktfühler nur den Stellantrieb (2) entsprechend jener Winkelprofilplatte (10) freigibt, welche die Rohrlänge nahe dem Ende mit dem größten Durchmessers abstützt, um die Winkelprofilplatte (10) unter dem Rohrende mit dem größten Durchmesser wegzuziehen.
