Loom heald-frame height adjusting apparatus

Abstract

A loom heald-frame height adjusting apparatus according to the invention includes a support base (51, 61, 71), an adjusting mechanism (52, 62), and an ascending-descending member (53, 63, 63', 73). The support base (51, 61, 71) includes a setup portion (51 d, 61 d) and a guiding portion (51 a, 62a), the setup portion (51 d, 61 d) enabling the support base (51, 61, 71) to be mounted on a heald frame (10), and the guiding portion (51 a, 62a) extending upward from the setup portion (51 d, 61 d) in a state where the support base (51, 61, 71) is mounted on the heald frame (10). The adjusting mechanism (52, 62) includes an adjusting portion (52a, 62a) and a shift portion (52b, 62b). The adjusting portion (52a, 62a) is supported by the support base (51,61,71) and includes a screw portion. The shift portion (52b, 62b) is allowed to be shifted in the direction in which the guiding portion (51 a, 62a) extends and screwed on the screw portion of the adjusting portion (52a, 62a). The ascending-descending member (53, 63, 63', 73) includes a support portion and a hook portion (53a). The support portion is supported by the shift portion (52b, 62b) of the adjusting mechanism (52, 62). The hook portion (53a) is capable of hooking a downward-facing surface of the frame stave (11).

Description

Technical field [0001] The present invention relates to a heald frame height position adjustment device for a loom, which is used in a loom, especially a loom equipped with a shedding device. The shedding device includes a plurality of heald frames for driving each of the above healds up and down. The shedding drive device of the frame, the drive transmission mechanism that is provided on each heald frame and connects the shedding drive device and the heald frame, that is, the drive transmission mechanism that can change the support height of the heald frame in the vertical direction, the height of the heald frame The position adjusting device is used for adjusting the height position of the heald frame before the loom starts operating. Background technique [0002] The opening device of the loom as described above is, for example, Figure 8 The device shown. The shedding device is provided with a plurality of drive transmission mechanisms provided corresponding to each heald fra...

Problems solved by technology

However, in the case of this structure, since such an engaging hole is not formed on a generally used heald frame, when the device of Patent Document 2 according to this structure is used on a loom that has been set, , it is necessary to re-implement hole processing on the heald frame

In addition, when the remanufactured heald frame has such a structure in which the engaging holes are formed, the number of man-hours for processing increases accordingly, leading to an increase in manufacturing cost.

Furthermore, the heald frame is driven vertically at high speed during weaving of the loom, but as a result of such engaging holes formed in the side stays, the strength of the heald frame may decrease.
