Definitions

  • the invention relates to a device for feeding weft threads to a Weft insertion organ in weaving machines.
  • the weft threads are drawn off from supply bobbins.
  • the weft thread to be entered into the shed is selected by a special facility and presented to the weft insertion member in such a way that the thread can be grasped by the entry member and then entered into the shed.
  • the thread feed device is equipped with a number of thread feeders for the individual weft threads drawn off from the supply bobbins, which have loops at their free ends for receiving the assigned thread.
  • the thread feeders are moved from a rest position into a working position which corresponds to the respective thread feeder and from there back into the rest position.
  • Various designs are known for such devices.
  • a guide device for the thread feeder is known from DE-PS 36 18 445. Thereafter, this guide device consists of a spatially adjustable structure, on which a carrier part and a guide part arranged at a distance below it are arranged for the thread feeders. The carrier part and the guide part have straight guides which make the entirety of the thread feeders appear fan-shaped.
  • the carrier part is, seen in the direction of the weft insertion, in its longitudinal extent obliquely to the path of the weft insertion member and in the direction of the heald frames pointing to the adjustable structure.
  • the straight guides in the carrier part are interlocked with one another in such a way that the thread feeders are displaceably guided in a spatially twisted fan area and that the individual eyelets of the thread feeders in the working position are in a compact arrangement on a line next to the path of the weft insertion element and essentially parallel to it .
  • the straight guides mentioned are formed in a strip of the carrier part and a row of second straight guides is provided in the guide part, the two rows being arranged at an angle to one another such that the straight guides of both rows can be displaced Thread feeders form the spatially twisted fan surface.
  • the known thread feeder device ensures to a particular degree that the positions of the thread feeding for the first to the last weft thread are so close together that it is possible to work with a relatively small looper stroke with precisely punctiform thread feeding for the weft thread transfer.
  • a weft thread selection and feed device for weaving machines operated with an electric motor for the selective movement of thread feeders between a ready position and a transfer position for the weft thread.
  • This device is characterized in that in a housing on a non-slip belt that wraps around a drive wheel and a deflection wheel with a certain diameter difference and a certain distance, the extended straight belt strand lines of action intersect at one point in the weft transfer position and that at each of the The two thread feeders attached move in the belt strand line of action and the thread feeders are attached so offset around the belt strand that one thread feeder is in the standby position, while the other thread feeder is in the transfer position and these positions are forcibly exchanged by turning the drive wheel.
  • This weft selection and feeding device gives the person skilled in the art the possibility to work with only a single thread feeder per device.
  • the prior art according to Article 54 (3) and (4) EPC also includes EP-A-0 598 264, relating to a device for selecting and delivering weft threads for a weaving machine.
  • the device also consists of individual units (modules).
  • the weft feeder In each unit, the weft feeder is guided in its longitudinal direction and can be moved between a rest position and a delivery position by means of an eccentric drive and its own drive motor.
  • the weft feeder is connected directly to the eccentric drive and guided such that the transverse movements of the feeder emanating from the eccentric drive are compensated for.
  • the above-mentioned electromotively operated weft selection and feeding devices do not disclose any technical means by which they can be spatially adjusted relative to the path of the weft insertion element and can be installed in these means without any significant effort.
  • the object of the invention is in a compared to the web of Weft insertion organ spatially adjustable device of a weaving machine To take precautions to exchange individual weft selection and enable feed devices with minimal assembly time.
  • each weft selection device at the outlet of the thread feeder has a connecting piece, for example a connecting piece which can be inserted into a carrier part known per se and equipped with straight guides and can be locked therein, and secondly has a quick-opening guide part for the thread feeder, means that everyone can change quickly Selection and feeding device given.
  • the carrying and guiding device and the thread selection and feeding device are shown in FIG. 1 as a unit.
  • the carrier part 1 and the guide part 2 are connected to one another by a connecting piece 3.
  • Both the carrier part 1 and the guide part 2 can, as is known from DE-PS 36 18 445, preferably have a curved shape.
  • the carrier part 1 has in a known manner external straight guides 4, which can be designed, for example, as through holes.
  • external straight guides 4 instead of the thread feeder 5, the outlet of the housing 7 of the weft thread selection and feeding device 8, which is designed as a socket 6, is received in the straight guides 4 and locked at position 9, for example by means of a clamping screw (not shown).
  • Each thread feeder 5 is guided inside the socket 6 for the first time.
  • a further guide takes place in the straight guide 10 of the guide part 2.
  • the two outer weft selection and feed devices 8 are connected to the carrier part 1.
  • the weft threads 11, 12 assigned to the devices 8 are to be entered here, for example, as a double weft.
  • the eyelets 13 at the ends of the thread feeder 5 define the length and position of an imaginary line 14 on which the eyelets of all the thread feeder 5 of the device 8 must lie in their working position.
  • the connecting piece 3 is clamped in a slotted block 15 by means of a screw 16. After loosening the screw 16, the entire device - support part 1, guide part 2 and weft selection and feed device 8 - can be moved both axially in the direction of the longitudinal axis of the connector 3 according to double arrow 3a of the connector 3 and / or about the longitudinal axis of the connector 3 according to the double arrow 3b of the connector 3 are rotated. In this way, the angular position of line 14 with respect to the path of the weft insertion member 17 can be adjusted and the overall height of the device relative to the path of the weft insertion member 17 can be changed.
  • the block 15 is within a bracket 18 in an elongated hole 19 according to Double arrow 15a slidably arranged. As a result, the device is also in its Parallel position to the path of the weft insertion member 17 adjustable.
  • the bracket 18 in turn is attached to a machine-fixed frame, not shown.
  • the weft thread selection and feed devices 8 necessary for the weaving process are held on the housing 7 in the carrier part 1 by means of connecting pieces 6.
  • a clamp connection eg producible by means of a screw, ensures that the devices 8 are locked in position 9.
  • the guide part 2 arranged below the carrier part 1 and carried by the connecting piece 3 is designed in such a way that the straight guides 10 therein are designed to be changeable for the thread feeders 5.
  • the guide part 2 consists of a base part 2a and an upper part 2b which can be loosely connected to the base part 2a.
  • the base part 2a is provided with half straight guides 10a and the upper part 2b with half straight guides 10b which are mirror images of the half straight guides 10a.
  • a guide element 20 present in the base part 2a outside the straight guides 10a protrudes through a longitudinal guide 21 arranged in the upper part 2b.
  • the upper part 2b is on the base part 2a slidable in the direction of the double arrow 22.
  • the straight guides 10 for the thread feeder 5 can be lifted and restored in a few simple steps.
  • the weft selection connected in FIG. 1 to the carrying and guiding device and feed devices 8 have for feeding the thread feeder 5 an electric motor 23, which is preferably an actuator, which also with the on the housing 7 arranged control device 24 in a signal-transmitting connection stands.
