Problems solved by technology

[0005] But the disadvantage is: in the case of the above-mentioned past warp let-off device, if the connection position of the pull rod 104 and the connecting rod 106 is changed to adjust the amount of slack, even if the warp yarn tension is the same, the tension detected by the tension detector will also occur. Phenomenon of detection value change
[0014] Moreover, in order to adjust the amount of slack, if the connecting position of the tie rod 104 and the connecting rod 106 is changed, the phenomenon that the rod length of the tie rod 104 (the distance between the first axis and the connecting position of the connecting rod 106) changes also acts on the first The change in the force of the shaft increases, and as a result, the detection value of the tension detector further changes

Embodiment Construction

[0046] according to Figure 1 to Figure 5 An example of the let-off device 1 of the loom using the positive easing mechanism 5 will be described. In the following description, the "front-rear direction" refers to the moving direction of the warp yarn according to feeding of the warp yarn. In addition, the take-up device side in the warp direction of the loom is referred to as "front side", and the let-off device 1 side is referred to as "rear side". figure 1 It is an explanatory diagram of the active easing mechanism 5 in the let-off device 1 of the above-mentioned loom. The black dots in the figure are the fulcrums directly or indirectly fixed on the rack. The white dots in the diagram are pivots that are not fixed to the rack. figure 2 It is a plan view of the warp let-off device 1 of the loom, and shows the right side part seen from the rear side. image 3 It is a plan view of the let-off device 1 of the loom, and shows the left side part seen from the rear side.

Abstract

The invention discloses a let-off device of a loom using a positive easing mechanism, which does not change a detection value detected by the tension detector before or after adjustment when the easing amount of the loom is adjusted. The let-off device of the loom uses a positive easing mechanism, which includes a tension lever supporting the easing roller and swingably supported by a first shaft, a second lever supporting the first shaft and swingably provided at a second shaft fixedly arranged at a frame (F) of the loom, and a drive mechanism coupled to the tension lever and driving the tension lever to swing. The drive mechanism includes a drive portion fixed to the frame (F), and a connecting rod coupled to the drive portion. The connecting rod is coupled to the tension lever via a third lever and a link, the third lever swingably provided at a third shaft fixedly arranged at the frame (F), the link coupled to the third lever.

Description

technical field [0001] The present invention relates to a warp let-off device of a loom using a positive easing mechanism that actively performs easing work on an easing roller that guides warp yarns pulled out from a let-off beam, and when the easing roller passes Tension detectors are installed on tie rods, etc., and the warp easing roller is used for the warp easing action and warp tension detection. Background technique [0002] Figure 6 A conventional example of a let-off device of a loom using an active easing mechanism is shown. Its structure is that in addition, in the following description, regarding the connection order of the driving device of each component in the let-off device of the loom, the connecting part on the side closer to the driving device is set as the driving side end part, and the far part is set as the driving side end part. The connecting portion on one side is used as the driven-side end portion. The warp yarn 101 drawn from the let-off beam ...
