Abstract

PURPOSE:To provide the subject device capable of reducing the thickness of a selector and of decreasing the repulsion of the selector caused by an inertia on the operation of the selector by superposing a thin plate-like spacer on the side surface of the selector in a laminate state and inserting the selector and the spacer into a needle groove. CONSTITUTION:When an actuator is operated to insert a selector 6 into a needle groove 2, a fine plate-like spacer 20 is superposed on the side surface of the selector 6 in a laminate state and inserted into the needle groove 2 together with the selector 6, thereby permitting to reduce the thickness of the selector 6 only in the thickness of the spacer 20 even when the width of the needle groove 2 into which the selector 6 is inserted is the same as that of the needle groove 2 into which the needle is inserted, and allowing to decrease the inertia force produced on the operation of the selector 6.

Description

[Detailed description of the invention]

[Industrial field of application χ The present invention relates to flat knitting a characterized by a support means for a selector used in a stockinette knitting machine.K Prior art] For selection of knitting needles when knitting a knitted fabric As shown in Fig. 4, an actuator 51, a selector 52, a select jack 53, a jack 54, a selector push-up cam 55, etc. are used, and the knitting needles are operated through these by the start of the actuator 51. , knitting, 111 machine, pattern, etc. The selection of knitting needles is carried out in the usual manner.The actuator 51 operates to select the selector 52 corresponding to the desired needle, and the selector 52 is activated by the selector push-up cam. 55, the select jack 53 is moved to a predetermined position, and at this position, the select jack pressure cam 56 pushes it down into the needle groove. 1. By pushing down the select jack 53, the jack 54 is pushed down, The shackbutt 57 changes its height and accordingly the predetermined cam 58
The needle 59 integrated with the jack 54 is selected. Since the selection of the selector 52 by the actuator 51 described above is performed during high-speed knitting, the contact between the protrusion 60 of the actuator 51 and the butt 61 of the selector 52 takes place in a very short period of time. It turns out. During this time, the predetermined selector 52 is set to the needle 21I.
62, the selector 52 receives an extremely strong impact between the actuator protrusion 60 and the selector butt 61, and the selector 52 that is pushed into the needle groove is subject to inertial force, and sometimes is pushed back again due to recoil. There have also been cases where the needle has come out of the needle groove 62 and the needle has been selected incorrectly. In order to prevent this, it has been considered to make the selector 52 wide-handed in order to reduce the inertial force of the selector 52. However, when such a selector is used, it is necessary to reduce the width of the needle groove in the part where the selector is fitted. Two types of needle beds had to be used: one with a In addition, since it is a problem if the selector 52 accidentally moves in the groove when inserted into the needle groove 62, in order to add sliding resistance to the needle groove, the selector 52 is slightly bent in a dogleg shape at the middle part, and both ends are bent slightly. Although the intermediate portion is made to resiliently abut against the wall of the needle FIO, the sliding resistance changes depending on the degree of bending, but it is difficult to keep the resistance value constant. K Problems to be Solved by the Invention] In view of the above points, the present invention reduces the repulsive force due to the inertia of the selector during needle selection operation by reducing the thickness of the selector, thereby reducing the sliding of the selector against the needle groove. The selector is bent uniformly to provide resistance.
To obtain a needle bed for a flat knitting machine that can obtain uniform sliding resistance of a selector with respect to a needle groove, and also allows insertion of a needle and a selector even in a needle bed with one type of needle groove width. Connect with purpose. [y! Means for solving the problem Inserted. Furthermore, the separator and/or spacer is made to have elasticity in the width direction of the needle groove by bending its intermediate portion, thereby producing sliding resistance with respect to the needle groove. K action] The selector and the separator are stacked together and inserted into the needle groove, and the selector and/or spacer are
Since the intermediate portion is bent, when inserted into the needle groove together with the selector, both ends and the intermediate bent portion exert a pressing force in the groove width direction. Since the spacer has a thin plate shape, it is easy to make the degree of bending uniform. Therefore, uniform sliding resistance can be generated for each selector in each needle groove. Also, even if the width of the needle groove where the spacer is inserted is the same as the needle groove where the needle is inserted, the thickness of the selector will be reduced by the spacer.
This reduces the lit of the selector and reduces the inertial force generated when the selector is operated.

[Example 1] An example of the needle bed of the present invention will be described below with reference to the drawings. Needle 3. is inserted into needle 21i2 of needle bed 1. Jack 4. Select jack 5. Insert selector 6. Above needle 3. Jack 4. Select jack 5. Since the relationship of the selector 6 is the same as in the conventional example, detailed explanation thereof will be omitted. The selector 6 has a hook 7 provided at its tip in the width direction of the needle bed 1 (direction perpendicular to the plane of the paper in FIG. 1).
The tail part 9 is made swingable, and bats 10, 11 and 12 are provided on the upper edge, and a hanging piece 13 is provided on the lower side. Above, part 9 includes the selector return cam 14 and the bat 11.
The rocker 16 of the actuator 15 and the butt 12 abut on a selector lowering cam (not shown), respectively. A thin plate-like spacer 20 is placed on the side of the selector 6.
Both the selector 6 and the spacer 20 are inserted into the needle groove 2 in a laminated body and with the spacer VIi freely between the two. The selector 6 and/or the spacer 20 can be made into a needle by bending the middle part into a dogleg shape. It has elasticity in the width direction of I42. As described above, the spacer 20 has a thin plate shape and has hooks 21 and 22 at the head and tail portions, respectively, and has an elastic support arm 24 extending from the base portion 23 extending in the longitudinal direction of the needle groove 2. In the embodiment shown in FIG. 2, the elastic support arm 24 extends in a mouth shape from the vicinity of the hook 21 provided on the head toward the hook 22 provided on the tail, and is biased so as to rebound toward the back of the needle groove. ing. The tip of the elastic support arm 24 contacts the upper edge of the selector jack 5 at a position closer to the tail than the wire 25, which is the fulcrum of the swing of the select jack 5, and moves the butt 26 of the select jack 5 out of the needle groove 2. It has the effect of pushing it out. In the above device, it is assumed that the hand movement action is now performed and the oscillator 16 of the actuator 15 is activated and comes into contact with the butt 11 of the selector 6. As a result, the selector 6
is pushed into the needle groove, but the spacer 20, which is laminated along the selector 6, is bent in a dogleg shape in the width direction of the groove, causing sliding resistance due to elasticity. Moreover, there is no attempt to move toward the outside of the groove due to repulsion from the depths of the groove due to inertia. Effects of the Invention: The needle bed of the present invention has a thin plate-like spacer attached to the side surface of the selector in a stacked IC state and inserted into the needle groove, so the width of the groove of the target submarine into which the selector is inserted and the needle Even if the needle groove width of the inserted part is the same width, comb the selector's 11 taste by the thickness of the spacer.
can be reduced, and the repulsion due to inertia when the selector is set to 0 can be reduced accordingly. In addition, in the case where the intermediate part of the selector and/or separator is made elastic in the width direction of the rod structure by making the middle part of the selector and/or separator (Kawanishi), it is possible to create sliding resistance against the 4+ groove, the above-mentioned inertia-induced movement is caused by the spacer. It is also suppressed by 17 friction between the selector and the selector.In history, the VI between the selector and the needle groove wall, which was obtained by bending the selector, was
By bending the spacer, the Je resistance can be changed into frictional resistance by bending the spacer.Since the spacer is thinner than by bending the selector, it is possible to obtain a more accurate bending angle, which in turn increases the ffi obtained. !
The friction coefficient can also be made uniform.
