Problems solved by technology

[0015] Furthermore, regarding the relationship between the selection head 8 and the selection pin guide surface 19 described above, because the contact between the two is a line contact, the selection head 8 will be generated as shown by the lower arrow on the right in Fig. 13 (f). It is difficult to obtain a stable abutting posture, which may cause malfunctions
[0016] Furthermore, in the case where the selection head 8 acts on the selection head 8 for some reason to bias the selection head 8 toward the non-contact posture side, as shown in FIG. Problems with occasional swinging forces (indicated by left-facing arrows) acting on body 9

Embodiment Construction

[0059] Hereinafter, an example in which an electronic jacquard device J provided with a plurality of electronic jacquard cassettes C according to the present invention is used for positioning control of the ejector bar TB of the Liba lace machine R will be described.

[0060] In the description, first, the structure of the Liba lace machine R and the outline of its operation will be described based on FIGS. 1 to 3 .

[0061] Liba Lace Machine

[0062] FIG. 1 is a diagram showing a schematic configuration of the Repa lace machine R, and FIG. 1 is a view of the Repa lace machine R viewed obliquely from the front.

[0063] The Liba lace machine R guides the bobbin thread w wound on a plurality of shafts Bm from the lower position of the machine table to the knitting part through the sley S, and forms a Liba lace by winding the bobbin thread w and the bobbin thread b RL, the formed Liba lace RL is alternately hooked and held by the back core bar BPB and the front core bar (not sh...

Abstract

An electronic driven jacquard apparatus includes a cassette having a select head pivotally selectable between a contacting posture contacting a select pin and a non-contacting posture not contacting the select pin in association with a bending movement of an operational member comprised of a piezoelectric body and a retaining pin providing a pivot for the select head, a jacquard machine body for fixedly supporting the cassette and a reciprocating mechanism for reciprocating the jacquard machine body along a longitudinal direction of the select pin. An end of the select pin facing the select head has a cubically convex shape whereas an end of the select head facing the select pin has a corresponding concave portion for receiving therein the cubically convex end of the select pin.

Description

technical field [0001] The present invention relates to an electronic jacquard device, and to a cassette for an electronic jacquard used in the device. Background technique [0002] The jacquard machine is a device equipped to control the position of multiple threads hanging on the machine table, and is a device for positioning each thread or multiple threads as a group of processing selection pins. Here, the selection pin equipped on the machine bed is biased in the direction of approaching or departing from the jacquard machine in its longitudinal direction. [0003] On the other hand, the jacquard main body is provided with a reciprocating mechanism for reciprocating the jacquard main body in the length direction of the selector pin, and the jacquard main body The relative positional relationship with the selection pin in the above-mentioned length direction changes. In the positional relationship where the main body of the jacquard machine and the selection pin are in ...
