Description

[Detailed description of the invention] The present invention relates to a temple for a loom.

In a loom, the weft threads woven between the warp threads by the looming process inevitably become wavy and tend to shrink the weave.
A temple is used as a device that guarantees the quality of a woven fabric by applying tension from both sides of the woven fabric to maintain a constant woven fabric.

Such a temple generally has a plurality of temple rings pivoted to a support shaft so that they can freely rotate diagonally through pushers serving as bearings. Tension is applied by pulling the woven fabric outward in the middle direction by the rotating temple ring, but in order to prevent so-called temple marks from forming, the angle of inclination of the multiple temple rings gradually increases toward the outside to increase the applied tension. is set so that it becomes larger toward the outside. However, in such temples, the angles of inclination of each temple ring with respect to the support axis are different, so the shape of each bush and temple ring must be changed depending on the angle of inclination, and there is no compatibility. However, parts management and assembly were extremely troublesome.

The present invention has focused on such conventional problems, and has been made with the object of combining a bush and a tensile ring of the same shape, and also making it possible to apply a smaller tension toward the inner side of the weave edge.

The present invention will be explained below with reference to an illustrated embodiment. In FIGS. 1 and 2, 1 is a warp, 2 is a woven fabric, 3 is a woven fabric, and temples 4 are provided on both sides of the woven fabric 3 near the woven fabric 2.

That is, a temple mount 8 is fixed to the temple bar 5 by a mounting piece 6 and a bolt 7, and a Tesopul roller 9, which will be described later, is attached to this temple mount 8. On the other hand, an arm 12 is fixed to the standing leg 10 of the temple mount 8 with bolts 11, and a temple cover 14 fixed to this arm 12 with bolts 13 covers the temple roller 9 from above. Here, the green on both sides of the woven fabric 3 is guided by the lower edge 15 on the front side of the temple cover 14, and passes between the temple cover 14 and the temple roller 9 while engaging with the roller 9. Lateral tension is applied by the loaf 9, and the temple cover 14
After being guided by the lower edge 16 on the front side of the fabric, it is guided to the upper surface of the temple bar 5 and transferred. temple roller 9
To explain the structure with reference to FIGS. 3 to 5, 20 is a support shaft, a thread 21 is formed at the inner end, and a sleeve 22 is iron-fitted at the middle part and fixed with a knock pin 23. be.

Several smoothers 24 are woven together in series with this sleeve 22, and a smoother 25 whose outer end surface forms an inclined surface with respect to the straight line of the support shaft 20 is also provided. and,
A number of temple ring assemblies 26, which will be described later, are iron-coupled in series with this base 25, and further a base 27 whose inner end surface forms an inclined surface with respect to the marling line of the support sea bream 20 is joined, This spacer 27 is fixed to the outer end of the support shaft 20 with a push screw 28. Each temple ring assembly 2
6 is a push 30 with an elliptical flange 31 inside
A temple ring 3 is rotatably attached to the boss portion 30a of the pusher 30 via a bearing metal 32.
3, and a large number of needle-like protrusions 34 are provided on the outer peripheral surface of the temple ring 33.

A through hole 35 is formed in the bush 301 obliquely to its center line (that is, the center of rotation of the temple ring 33), and the support shaft 201 is inserted through this through hole 35. Further, the center axis of the post portion 30a of the bush 30 and the inner surface 31a of the flange 31 are perpendicular to each other, and the flange 3
The outer end surface 31b of the first outer end surface 31b is formed to be inclined at a predetermined angle with respect to the rut line of the through hole 35 and the central axis of the boss portion 30a. Note that the end surface 30b of the boss portion 30a is formed perpendicular to the central axis of the boss portion. The method of forming the bush 30 will be explained with reference to FIG. 6. The jig 50' has a mounting surface 51 that is orthogonal to an axis B that obliquely intersects with the axis A at an inclination angle a, and a vehicle line B. A mounting hole 52 is formed in the same direction as the mounting hole 52, and a jig 60 is rotatably mounted in the mounting hole 52.

The paint 601 forms a mounting surface 61 perpendicular to an axis C obliquely intersecting the axis B at an inclination angle a, and a mounting hole 62 extending in the same direction as the axis C. Then, the jig 60 is rotated against the jig 5, and the rotational position where the mounting surface 61 of the jig 60 is perpendicular to the axis A is set as oo, and indexing is possible in units of 3 minutes from 00 to 180, for example. A scale 53 corresponding to the mark 63 attached to the jig 60' is marked on the mounting surface 51 of the jig 50 so that the jig 60' is attached to the scale 53. Numeral 65 is a bolt hole for fixing the bath fixture 60, and 66 is a bolt hole for fixing a preformed bush of the jig 601, which will be described later.

When forming, first, a line parallel to the axis of the round bar is carved on the surface of the round bar. Next, the rotary shaft and the bream line of the round birch are cut with a lathe at an angle of 01, and a bush is preformed in which the boss portion 30a, the end surface 30b, the inner surface 31a of the flange, and the outer end surface 31b of the flange are made parallel. At this time, the carved line is located on a plane containing the axis of the round bar and the rotation axis of the lathe. Next, the inner surface 31a of the flange is attached to the mounting hole 62 of the pick-up tool 60, as shown in FIG. First, the ridge tool 60 is aligned with the jig 5 to the position oo, and then both are fixed, and the long axis of the preformed push oval flange 31 is in a plane including the rut lines A and B. bushing 30 so that it is located on the same plane as
After aligning the mark 36 made on the circumferential surface of the flange 31 with the mark 64 made on the mounting surface 61 of the pick-up tool 60, the tush 30 and the jig 60 are fixed. The through hole 35 of the push 30 is machined. Note that the mark 36 here is a line carved in advance on the round bar as described above. Next, the jig 60 is rotated relative to the jig 50, the position of the mark 63 is shifted from oo by a predetermined angle (for example, 2o), and then fixed. In this state, the outer end surface 31b of the flange 31 of the bush 30 is aligned with the axis A. Machined so that it is perpendicular to the As a result, the outer end surface 31b of the flange 31 is not parallel to the inner surface 31a, and the outer end surface 31b is inclined at a predetermined angle with respect to the axis of the through hole 35 and the central axis of the boss portion 30a. Bush 30 created in this way and ten bull ring 3
A plurality of assemblies 26, each of which is a combination of 3 and a bearing metal 32 as required, are placed between the basers 25 and 27 so that the inclined outer end surface 31b of the bush 30 is parallel to the opposing adjacent bush end surface 30b. When aligned, the plane containing the center of rotation of the temple ring 33 and the axis of the through hole 35 in each assembly 26, and therefore the mark 36, will be sequentially shifted in the direction of rotation of the temple ring 33.

Such a temple roller 9, as shown in FIG.
The inner woven part of the support shaft 20 is fixed to the temple mount 8 with the nut 29. At this time, the mark 36 attached to the flange 31 of the innermost push 30 is positioned slightly forward of the part S where engagement with the woven fabric begins. and position the outermost mark 36 near the top of the roller ahead of it.

Next, the effect will be explained.

The wire rod 3 of the temple ring 33 is passed over the temple roller 9.
When the woven fabric 3 advances by engaging with the temple ring 4, the temple ring 33 is rotated accordingly.

At this time, the temple ring 33 rotates diagonally, and the woven fabric 3
However, as is clear from FIG. 3, the pulling distance 1 of the inner temple ring 33 from the engagement start point S with the woven fabric is small, and the outer temple ring 3
3, the towing distance 1 becomes larger. Therefore, it is possible to increase the pulling distance 1 toward the outside in the medial direction and increase the applied tension as the outer side of the weave becomes larger. In the above-described embodiment, the end surface 30b of the bush is tilted to a plane perpendicular to the axis of the through hole 35, and this surface 30b is parallel to the inner surface 31a of the flange of the bush adjacent to this end surface. The same effect can be obtained by assembling as shown. Since the present invention is as described above, even if bushes and temple rings of the same shape are combined, the outward pulling distance can be made different between the inner one and the outer one, thereby creating a so-called temple mark. Not only can neutralization be performed properly without causing any damage, but also parts management and assembly are extremely easy.
