Definitions

  • the invention relates to a device for training for a jacquard machine with between a high and a low position in a frame slidably guided boards, with a lifting device for the boards, which are supported by pawls in the frame to prevent them from moving are held, and with electromagnets to control the pawls.
  • pawls and electromagnets can be assigned construction effort increases with the number of harness cords and with it the susceptibility to disturbances. Because of the necessarily compact design of the circuit boards, pawls and electromagnets Accessibility to these structural parts complicates, which is comparatively long downtimes to remedy malfunctions.
  • the invention is therefore based on the object of a device for Specialist training for a jacquard machine of the type described above to design that in a malfunction a simple, little time-consuming Troubleshooting can be ensured.
  • the invention solves this problem in that the electromagnet arranged at least on a support detachably held in the frame are.
  • the electromagnets the pawls that drive them should be as close as possible, so that the slide from the frame the support with the electromagnet formed unit without disability pulled out of the frame by other construction parts past the latches can be.
  • the sliding guide can be made from a receiving groove for the wearer exist, it is recommended to place the electromagnet on the sliding guide Arrange the opposite side of the carrier to one hand for the carrier to achieve secure mounting in the frame and on the other hand favorable space to create the assignment of the electromagnets to the pawls.
  • the electromagnets can the carrier via a common, releasable electrical coupling to the control device be connected. To replace the by the carrier and the electromagnet formed unit therefore only needs the electrical coupling between the electromagnets and the control device to be solved.
  • the electromagnets on at least two detachably held in the frame Provide carriers to the size of the formed by the carrier To be able to limit units to a manageable size. With one The electromagnets are divided into two or more carriers Clear structure obtained despite the possible variety of electromagnets whose maintenance makes it easy.
  • the device 10 for shedding for a jacquard machine has a frame 11, which rests on a base 12 and an upper part 13 and forms a lower part 14. 2, the frame 11 is made of modular Assembled units, each two side walls 15 and include a foot portion 16 connected thereto.
  • the units of the Frame 11 form an elongated, substantially rectangular receiving groove 17, with their parallel longitudinal edges 18 a dovetail Cross section shows (Fig. 4).
  • spring 20 is provided for eyelets 25, which between a high position 26 and a low position 27 each relocated can be.
  • the warp threads, not shown, passed through the eyelets 25 thus form a compartment 28, which is due to a displacement of selected eyelets can be switched between their high and low positions.
  • the Warp threads run through a harness section of the frame 11, which is preferably comprises only a single harness base 29 which has a harness section forms in a laterally open C-shape with the advantage that the Eyelets 25 for pulling through the warp threads are easily accessible.
  • the harness cords 30 are at their ends 31 on the frame 11 and attached to the eyelets 25 with their other ends 32. Via train blocks 40 the harness cords 30 are connected with strands 35, the ends of which are 36 and 37, as can be seen in particular from FIG. 3.
  • a plurality of printed circuit boards 43 are mounted in the frame 11 and are connected via the strands 35, the pull blocks 40 and the harness cords 30 with the eyelets 25 in drive connection stand.
  • 3 is a pair of boards 43 on one Strand 35 attached so that the boards 43 each pair with the associated Eyelets 25 are connected.
  • Each board 43 is along a predetermined one Travel back and forth, as shown by the double arrow 44 in Fig. 3 is indicated.
  • the boards 43 can be brought into engagement with lifting knives 47 are, which are slidably mounted on the frame 11. This lifting knife 47 are arranged in pairs and act with the pairs of boards together, substantially along the travel path 44 of the boards 43 are moved.
  • a plurality of pawls 50 is also stored, the along a travel path 51, for example by pivoting between an open and a locked position can be shifted to the boards 43 cooperate.
  • 5 are the locking position denoted by 52 and the open position by 53.
  • Each jack 50 is in the Sense of the locking position 52 by a spring element 54, for example a coil spring.
  • Electromagnets 55 which act on, interact with pawls 50 a carrier 56 are attached.
  • the front and back of the wearer face the reference numerals 57 and 58.
  • the carrier is a dovetail shape has complementary form, he can easily in the Recording groove 17 are introduced.
  • the electromagnets 55 are accordingly open the front 57 of the carrier 56 is arranged.
  • the individual electromagnets 55 form an easily exchangeable structural unit with the associated carrier 56 59.
  • a circuit board is between the carrier 56 and the electromagnet 55 60 provided the electrical connections to the individual Provides electromagnets of the respective assembly 59.
  • This Printed circuit board 60 serves a releasable electrical coupling 61.
  • the electromagnets 55 of each assembly 59 are in at least two parallel rows 63 and 64 arranged. The arrangement is made so that within the rows 63 and 64 the electromagnets 55 have the same distance have, but the two rows 63 and 64 are offset, so that the Distance between the immediately successive electromagnets 55 of the two rows 63 and 64 only half the distance between the electromagnets corresponds to a row.
  • the units 59 with the electromagnets 55 can 2 and 3 laterally in one structural unit of the frame 11th are inserted, with a sliding guide through the receiving groove 17 for the carrier 56 results. 3 are in the inserted position the electromagnets 55 are aligned with the associated pawls 50. According to the double arrow 66, the assembly 59 can be between one inserted position 67 and an extended position 68 are, as can be seen in FIGS. 2 and 3.
  • each electromagnet acts 55 together with two of the pawls 50 arranged in pairs, wherein each pair of pawls with one arranged on a common strand 35 Pair of boards 43 cooperates to the corresponding eyelet 25 accordingly head for. Since each jack 50 of a pair of jacks each half of the associated Is assigned to an electromagnet, an electromagnet 55 is sufficient Control the movement of the associated eyelet 25.
  • the assembly 59 for the electromagnet 55 is electrically connected to one Control device 70 connected (Fig. 2), for example by a programmable computer can be formed. Via the electrical clutch 61 can the connection between the individual electromagnets 55 and of the control device 70 can be produced or solved in a simple manner. It need not be explained in more detail that the clutch 61 with the Control device 70 can be connected to a structural unit to connecting cables to avoid between the control device 70 and the clutch 61.
  • the operation of the Device 10 can be resumed after a short interruption.
  • the invention is of course not based on the illustrated embodiment limited because it is not on the construction of the drive connections between the boards 43 and the eyelets 25 or the type of locking the boards 43 arrives via pawls 50, but only that the pawls 50 are controlled by electromagnets, which at least a detachable carrier 56 are attached.
