Definitions

  • ABSTRACT An apparatus for moving thread guide devices of textile machines wherein two traction elements are provided which move to-and-fro in a translatory fashion in opposition to one another between two terminal positions, these traction elements being coupled with one another by a connection element and via the latter acting upon the thread guide devices.
  • a stationary retaining or holding element is associated with each traction element and each such retaining element selectively retains the associated traction element in one terminal position in accordance with a control program.
  • Such type equipment for moving the thread guide devices such as the shed forming devices of looms, for instance harnesses or heddle wires, filling guide elements of multi-shuttle looms or stitch deposit devices of knitting machines, are known in a great many different variations. With this equipment the threads or yarns guided by the thread guide devices are selectively moved to-and-fro between two positions in accordance with a control program which is dependent upon the desired weaving of the fabric or the deposit of the stitches of the knitted fabric.
  • the inventive apparatus is manifested by the features that there are provided two translatory to-and-fro moving traction elements which move in opposition to one another, that is to say opposite in phase, between two terminal positions.
  • a connection element interconnects these two traction elements with one another and the latter act upon the thread guide devices through the agency of the connection element.
  • Each traction element has associated therewith a stationary retaining or holding element which selectively retains the associated traction element in one terminal position as the function of a control program.
  • FIGURE schematically depicts an apparatus for moving a thread guide device which, for instance, has been illustrated by way of example as a heddle wire.
  • a thread guide device which, for instance, has been illustrated by way of example as a heddle wire.
  • a number thereof could be employed which would be then arranged in a harness frame as is well known in the loom art.
  • thread as employed herein, is used in a broader sense as not only encompassing threads as such, but also yarn and other filamentary material as same is generally processed at a textile machine.
  • the heddle wire 1 possesses an eye or eyelet 2 for the throughpassage of a thread 3.
  • Heddle wire 1 is secured at one end to a spring 4 and at its other end is connected with the pivot shaft 6 of a roller 7.
  • a connection element 8 for instance, a cable or a chain which is connected at its ends with rod-shaped traction hooks 9 and 10 respectively.
  • Each traction hook 9 and 10 possesses at its free end a hook member 9a and 100.
  • At each hook member 9a and 10a there is furthermore secured a stop or impact element 11 and 12 respectively.
  • Each such stop or impact element 11 and 12 cooperates with a guide device 13 and 14 respectively which can oscillate back-and-forth between two positions A and B.
  • the guide devices 13 and 14 are driven by a respective schematically illustrated drive mechanism 15 and 16 so as to move in opposed relationship, i.e. phase opposition with respect to one another.
  • drive mechanism l5 and 16 can be, for instance, a drive crank.
  • Each of the guide devices 13 and 14 is provided with an opening 13a and 14a respectively through which there can slidably move the associated traction hook 9 and 10 respectively.
  • Each of the guide devices 13 and 14 work at both sides of the associated traction hook 9 and 10 upon the associated impact or stop element 11 and 12, so that the forces exerted by each guide device upon the associated stop element act symmetrically with respect to the associated traction hook and thus there does not occur any force moment which acts transversely with respect to the direction of movement of each traction hook.
  • a respective retaining hook member 17 and 18 which serves as a holding or retaining element is associated with each traction hook 9 and 10 respectively.
  • Each retaining hook member 17 and 18 is rotatably mounted about a stationary shaft or axle l9 and 20 respectively and is connected with a spring 21 and 22 respectively which retains the associated retaining hook member 17 and 18 in a work or effective position in which the retaining books can engage behind the hook members 9a and 10a of the traction hooks 9 and 10 respectively, with the result that the traction hooks are fixedly retained in the corresponding position.
  • the retaining hooks 17 and 18 are designed as armatures of electromagnets 23 and 24 respectively. If these electromagnets 23 and 24 are energized by delivering current from a suitable and therefore not particularly illustrated supply source to their input terminals 23a, 23b and 24a, 24b respectively, then the retaining hooks l7 and 18 respectively, are attracted or activated and moved out of their effectual position into a release position where they no longer cooperate with the hook members 9a and 10a of the traction hooks 9 and 10 respectively.
  • the traction hooks 9 and 10 are likewise moved in phase opposition between two terminal positions, and specifically for such length of time as the retaining hooks are held in their release or ineffectual position.
  • the retaining hook 17 will be located, under the action of the spring 21, in its effectual or work position in which the retaining hook 17 holds or retains the traction hook 9 positionally fixed. If during the next working cycle the other traction hook 10 is moved in the described manner towards the retaining hook 18, then, the roller 7 together with its pivot shaft or axle 6 will be guided in the guide 5, against the force of the spring 4, so as to move into the position 7' depicted in phantom lines in the drawing, with the result that the heddle wire 1 and the thread 3 or the like is likewise moved in the same direction.
  • the electromagnets for instance the electromagnet 23
  • the roller 6 remains for such length of time in its position 7' as both traction hooks 9 and 10 are retained in their lower terminal position.
  • control program as a function of the momentary position of the thread 3 which is determined by the desired weaving or connection of the fabric or the deposition of the stitches of the knitted fabric.
  • control program can be provided in known manner, for instance, in the form of a punched card or a magnetic storage upon a magnetic type, as is well known in the art.
  • the program control has only been conveniently schematically indicated by reference character 30.
  • the electromagnets 23 and 24 must be designed in such a way that during energization thereof the retaining hooks l7 and 18 which serve as the armatures of the magnets are retracted. It is also possible to provide devices, which are controlled by the control program such that the corresponding retaining hooks is moved mechanically into its release position in which it bears at the magnet and then need only be fixedly held in this position thereby.
  • retaining hooks not as themselves armatures of electromagnets, rather to connect such via a rod with a separate magnet armature serving as the actuation element of a magnet.
  • the thread guide device is illustrated as directly engaging at the roller 7. However, it is possible to interpose further rollers between the roller 7 and the thread guide device 1 in order to accommodate the magnitude of the displacement of the eyelet 2 and therefore the thread 3 for a given displacement path of the shaft 6 of the roller 7.
  • An apparatus for moving a single thread guide device of textile machines comprising two traction elements, means for moving said two traction elements to-and-fro in translatory fashion in opposition to one another between two terminal positions, connection means inter-connecting said two traction elements with one another and acting upon the single thread guide device, a stationary retaining element operatively associated with each traction element for selectively retaining the associated traction element in one terminal position as a function of a control program to selectively vary the position of the single thread guide device.
  • each traction element is displaceably guided through the associated guide mechanism and possesses a stop element which cooperates with the associated guide mechanism.
  • retaining hook member is coupled with a return mechanism which, as a function of the control program, serves to bring the associated retaining hook member, against the action of the spring means, so as to bear at the associated electromagnet.
