Definitions

  • the invention relates to a selection device for textile machines, such as jacquard, rustling or card beating machines, for the pattern-based actuation of reading or other control elements, for. B. for pressing control needles or read-in slides or circuit boards or the like.,
  • a number of bending by impressing an electric or magnetic field such as rod or strip-shaped bending transducers arranged in a frame or frame parallel to each other and each with a locking element which can be moved back and forth between two positions, the individual locking element striking or not striking against the reading element assigned to it depending on the deflection of the bending oscillators when the device and the reading elements move relative.
  • Textile machines which have selection devices that work with such bending vibrators, are already known (e.g. DE-PS 22 30 487, DE-PS 21 30 502 and DE-AS 25 09 217).
  • the flexural vibrators are firmly clamped at one end in a frame, while their free end swings back and forth and thereby moves a locking slide or the like, which is supported on the frame, between two positions.
  • the respective position of the control slide is scanned by push-off needles which act on circuit boards or the like.
  • the flexible oscillators which are tensioned on one side, can only transmit very small forces with their movable free end, since their brittle material tends to break even at low stresses.
  • the object of the invention is therefore to provide a simple design of the selection device which is more stable, more compact and takes up less space.
  • the solution to this problem is that the flexural vibrators are supported with their two ends at two opposite points and the locking element supported on the housing is fastened in the region of the antinode located between the two bearing points. This gives a stable and compact arrangement.
  • the locking element supported on the housing absorbs the forces exerted by the push-off needles or other reading elements.
  • a particularly space-saving design is achieved in that the individual flexural vibrators are arranged in a parallel position with their one end next to the end of the reading elements which are respectively assigned to them and are also rod-shaped or strip-shaped.
  • a support stop for the locking element which is arranged between two bending oscillators, is at the same time designed as a limit stop for the movement stroke of the bending oscillators.
  • the flexible oscillators are loosely supported with their ends in the bearing points. This can happen, for example, in that the ends of the oscillators are mounted in conical slots or in that the ends are held in elastically flexible bearing elements. This avoids unnecessary bending stresses.
  • guide bores 10a are provided in the horizontal direction (FIGS. 1 and 3) through which the Ends 33 of the push-off elements 9 are guided.
  • the plastic housing is designed as a base plate 16 (FIGS. 2 and 4) on which ridges are formed at the rear and front or on both sides, which serve to guide the push-off elements 9 and to support strip-shaped bending oscillators 2. These increases can for example consist of one piece with the base plate 1 b.
  • Conical slots 3a (see FIGS. 1 and 2), in which the left side of the bending oscillator 2 is mounted, are provided in the elevations 3 at the rear and front of the base plate 1b.
  • conical slots 3a are also provided on the right-hand side, which serve for the right-hand mounting of the bending vibrator.
  • the bending vibrator 2 is mounted on the left and right in these two slots.
  • the elevations 8 are formed at the back and front, which serve as a stop or as an anvil for the locking element 5, which is connected to the flexural oscillator via the elastic adhesive connection 6.
  • the axial force of the push-off element is absorbed on the stop surface 8a.
  • At the left end of the bending vibrator there is an adjusting ring 4 which prevents the bending vibrator from moving horizontally to the right. For better function and high operational reliability or to eliminate thermal expansion, the bending oscillator is cut in between the adjusting ring 4 and the blocking element 5 with the play Z.
  • each bending vibrator locking elements 5 are attached via an elastic adhesive connection 6, which are made of plastic, for. B. made of polyamide, and these have an insert 7 from hardened tetem steel. On them hit the push-off elements 9 during operation, for. B. in the locked position 2b (bottom, Fig. 1 and Fig. 3).
  • the installation of the flexural vibrators 2 on both sides into the plastic housing 1 is very simple, they are pushed completely into the slots 3a of the elevations 3 and 10 with the locking piece 5 and the limiting adjusting ring 4 at the rear and front of the housing 1.
  • the cover plates la serve as a lateral limitation at the rear and front.
  • the locking pieces 5 are laterally delimited or guided on the surfaces 11 and 11a, so that no twisting of the locking piece 5 or the bending vibrator 2 can occur.
  • the bending vibrators 2 receive voltage via electrical supply lines 12 in accordance with a textile pattern program for the card-beating machine or a textile pattern program for the Raschel machine, so that they move in one direction (position 2a, up) or in the other direction (position 2b, down), for example. be deflected.
  • the de-energized middle position is designated by 2.
  • the blocking elements 5 likewise go into the blocking position 2b or inactive position 2a, or they remain in the central position.
  • the push-off elements and bending vibrators move relative to one another in the direction of their longitudinal axis.
  • the push-off elements 9 in position 9a d. that is, a left-hand scanning movement of the push-off elements 9 is blocked.
  • Other impression elements 9 are brought into position 9b by the scanning movement running to the left.
  • the length of the locking element 5 is at least as long as the stroke of the push-off element must be.
  • the stroke of each locking element 5 or each bending vibrator 2 is limited by the stops 8b below and 8c above.
  • the latter is held in a rubber or plastic bearing 4a instead of in slots in the ends on the left and right approximately in the vibration nodes.
  • Foam rubber 4a which is held in the recess 3b and can be used as the storage medium, for example, and since this is very elastic, it is not important for the storage to be positioned exactly.
  • drop plates 13 are arranged in a frame, which, depending on the position of the recess 14 in the push-off element 9, are moved downward by means of corresponding intermediate links, such as drop pins, push pins and Transfer rams that affect stamps.
  • the push-off elements 9 are designed as a reading element, in the example shown here as a narrow, elongated slide that can be moved in the horizontal direction.
  • the read-in elements are arranged in the form of 84 groups of 16 elements, one above the other in one plane.
  • the push-off elements 9 are driven by a pressure rake 15 which can be moved back and forth according to arrow X. Springs 17 are inserted on the left ends 16 of the push-off elements in FIG. 5, which are guided in the push-off rake 15.
  • These falling boards 13 have laterally outwardly projecting pins 19 with which they can rest on the read-in slides 9.
  • the pins 19 of the first 8 fall boards are directed to one side and those of the 8 other fall boards to the other side.
  • the slide 18 with the drop plates 13 hanging thereon via the pins 20 is moved upward.
  • the pressure rake 15 is moved to the right by the machine drive, not shown, and the reading elements can be moved horizontally to the right into the selection position or not via the spring 17, depending on the position of the locking element 5 actuated by the control element 2 mounted in the housing 21.
  • the blocking element 5 has moved downwards in accordance with the information from the selection electronics, the scanning movement of the reading element 9 is blocked and there is no horizontal movement, only the spring 17 is compressed. If the blocking element 5 is in the upper position, the read-in element can carry out the horizontal movement via the spring 17.
  • the falling plates 13 are supported with their pins 19, depending on the position of the reading element 9 assigned to them, either on its upper edge or, if the reading element assigned to them has not been locked, they fall into the recess provided for this purpose 14 of its reading element 9, which is in the below located pushing needle mechanism 22 of the card punching machine lower the corresponding pushing needles and the corresponding punch 23 is actuated via the pressure rake 24.
  • boards 25 are arranged in a frame 29 which can be coupled to the lifting knives 26. From the boards 25, the displacer pins 27 are moved upwards into the pattern-like selection position via control cables 28.
  • the boards 25 are pressed off by horizontal pressing elements 9, i. H. moved back and forth according to arrow X 'so that their hook 34 z. B. stand outside or within the range of the lifting knife 26 (uncoupling and coupling).
  • the push-off elements 9, which are designed as narrow, elongated read-in slides, are driven by a pressure rake 30 which is moved back and forth according to arrow X.
  • springs 32 are inserted, via which the horizontal movement of the read-in slides 9 takes place.
  • the selection device 21 is located at the left end 33 of the reading slide.
  • flexural vibrators 2 of the type described are combined in rows and blocks in a frame 21 and are shaded in place of the known pre-needle mechanism of a jacquard machine. From any information provider, not shown, such.
  • the piezoelectric flexural vibrators receive 2 control pulses. These impulses cause the blocking elements 5 and the bending vibrators 2 to come into a defined position directed upwards or downwards (FIGS. 1 and 3), that is to say come to rest between the ridges 8 on one of the two abutment surfaces 8b or 8c and remain there under the effect of the electrical force accordingly.
  • These control needles 9 are guided in the guide plate 35.
  • the control needles 9 decouple the sinkers 37 from the lifting knives 36 of the jacquard machine. When these lifting knives 36 subsequently ramp up, these sinkers 37, which they have uncoupled, and the warp threads, not shown, which they actuate, remain in the lower position in the weaving machine.
  • the blocking elements 5 of the flexural vibrators 2 act in an equivalent manner on the pressure elements 9, which are known to be designed as control needles in dobby machines, which in turn bring the lifting pins 39 into or outside the area of the auxiliary knives 40.
  • lifting pins 39 brought out of the area of the auxiliary knives 40 by the control needles or push-off elements 9 which are actuated by the blocking elements 5 and which are guided in the guide 38 remain in the low position.
  • the boards 41 remain in Lowering assigned to the main knives 42 or 43 of the dobby, which spend the heald frames in the raised position in their action via them, balance lever 44 and shaft lever 45.
  • the heald frames assigned to these sinkers will therefore remain in the lower position, which also forms the shed compartment prescribed according to the pattern.
