Problems solved by technology

[0006] But the disadvantage is: these all use a pair of left and right height adjustment mechanisms corresponding to the components of the number of heald frames, so the manufacturing cost of the shedding device increases
Therefore, the structure in which the height adjustment mechanism is fixed to the heald frame is not suitable for increasing the speed of the vertical movement of the heald frame.

Embodiment Construction

[0032] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0033] according to Figure 9 ~ Figure 11 An example of a loom to which the heald frame height adjusting device 1 is applied will be described. Figure 9 The structure which raises and lowers the heald frame 90 is shown. Figure 10 The structure of the left side of the leading heald frame 90 is shown. Figure 11 A structure in which the shedding device 80 supports the heald frame 90 from below is shown.

[0034] An example of a loom suitable for the heald frame height adjusting device 1 is as follows: Guide rails 91 are provided on the left and right sides of the heald frame 90, and the guide rails 91 guide the vertically moving heald frame 90 in the front, rear, left and right directions, and pass through the opening below the heald frame 90. The device 80 moves the heald frame 90 up and down. Hereinafter, it will be further describ...

Abstract

The present invention provides a heald-frame height adjusting apparatus to make it possible to overcome the problems by providing a heald-frame height adjusting apparatus that easily adjusts the height of a heald frame and that reduces manufacturing costs of a shedding device, and that does not allow the shedding device to easily malfunction and that is suitable for high-speed vertical movement of the heald frame. A heald-frame height adjusting apparatus used in a shedding device including a drive transmission mechanism which is provided in accordance with each heald frame, which connects a reciprocating driving device and a heald frame with each other, and which is capable of changing a supporting height of the corresponding heald frame. The heald-frame height adjusting apparatus includes engaging means and raising-lowering means, the engaging means being engageable with and disengageable from the heald frame and being engaged with the heald frame when the height of the heald frame is adjusted before starting an operation of a loom, the raising-lowering means being placed at a securing portion of the loom and moving the engaging means vertically with respect to the securing portion.

Description

technical field [0001] The invention relates to a device for adjusting the height of a heald frame of a loom. Background technique [0002] In the loom, if the height of the heald frame is not properly set and the loom is operated, accidents such as poor shedding and fabric tearing during beating are likely to occur. Therefore, the work of adjusting the height of the heald frame is carried out so that weft is beaten at the appropriate position of the steel buckle. [0003] For example in Figure 9 In the shedding device of the loom shown, a drive transmission mechanism is set on each heald frame, and the motion of the reciprocating drive device is converted into the up and down motion of the heald frame through the drive transmission mechanism. Moreover, the left and right parts of the heald frame are supported from the bottom by telescopic rods in the drive transmission mechanism. The telescopic pole can change the overall height, but it does not have a height adjustment ...
