Description

[Detailed explanation of the invention] This invention places a jack above each knitting needle arranged in a row on the needle bed to act on the butt of the knitting needle to move it, and selectively acts on the jack. In a knitting machine equipped with a selection member for sorting up and down or front to back, the selection member is arranged below the row of knitting needles, and the knitting needles can freely move back and forth across the upper side of the selection member. This invention relates to a jack selection device for a knitting machine in which a selection action piece causes a desired jack selection operation when the selection member is moved to an action position, and the selection member is passed from the upper side of the selection member between the knitting needles to a high height. The protruding slender selection action piece is reinforced by an auxiliary leg that protrudes from the upper side of the selection member to an intermediate position that is higher than the height of the knitting needle and lower than the height of the jack, and the auxiliary leg prevents the movement of the knitting needle from being obstructed. The purpose of this invention is to provide the most rational and durable structure of a jack selection device for a knitting machine, which has a structure in which the jacks and knitting needles are arranged in two rows above and below on a selection member. It is something to do.

An embodiment of the present invention will be described with reference to the accompanying drawings.

A needle bed 1 is provided with a front knitting needle planting needle groove 2 and a rear jack planting needle groove 3 aligned back and forth, and a guide rail 4 is fixed on the upper surface between the needle grooves 2 and 3.

The knitting needles 6 are supported by passing through the lower hole of the supporting leg plate 5 of the needle bed 1, and the rear end 6a of the needle stem is formed into a pyramidal shape and sharpened as shown in FIG. stand out.

The jack 9 is passed through the upper hole of the support leg plate 5, and the rear part is movably passed through a comb-tooth groove formed at the upper end of the bending plate 21 (to be described later) to allow the butt 10 to protrude upward from the needle groove 3. The front end of the knitting needle 6 is made to correspond to the rear surface of the butt 7 of the knitting needle 6 so as to be able to abut against it.

8 is a braking spring in elastic contact with the lower surface of the knitting needle 6, and 11 is a floating spring hung on the lower surface of the jack 9 to keep the jack 9 in a horizontal position at all times.

Reference numeral 12 designates a plurality of (eight in this embodiment) selection members disposed horizontally on the lower rear side of the knitting needle 6 so as to correspond to the lower surface of the jack 9; A support plate 19 is provided on the front side for inserting and supporting the front end of the operating rod 27 passed through in a locking or loose manner, and a horizontal bend 20 is provided forward in a portion of the support plate that matches the support height of the knitting needle 6. A bent plate 21 is provided at the front end of the bent plate 20, and the jack 9 is passed through the comb tooth groove on the upper edge of the bent plate as described above.

The horizontal bend 20 is provided with an entry/exit hole 22 through which the sharp rear end 6a of the needle stem of the knitting needle 6 passes.

As shown in an enlarged view in FIG. 3, the entrance/exit hole 22 has a guide portion 22 having an inclined side edge wider than the width of the needle groove 2 at the front end.
a, whose rear end almost matches the width of the needle stem of the knitting needle 6, and when the knitting needle 6 moves backward after moving forward, the rear end of the needle stem is passed from the guide part 22a through the entrance/exit hole 22, and the rear end is Let it slip out,
This entry/exit hole 22 allows the sharp rear end 6a to cross over the main body 13 of the selection member 12 and pass rearward without causing any lateral deflection.

The plurality of selection members 12 are configured to cause a lateral movement corresponding to an interval within half a pitch of each of the knitting needles 6 and jacks 9 to move the working position to the non-working position. As shown in FIG. 2.4, the thin selection actuating pieces 14 that protrude between the knitting needles 6 and the jacks 9 spaced apart by a certain distance are protruded, and the respective protruding positions are adjusted to the respective selection members 12.
Make a difference every time.

The selection action piece 14 has one upper side surface adapted to be able to hold the jack 9, and is provided with a support slope 15 that locks the jack 9 so that it cannot be lowered when moved to the action position.

In the non-operating position shown in FIG. 2, the jack 9 is not supported by the support slope 15 and freely descends against the elastic force of the floating spring 11.

On one left and right side of the selection action piece 14, a needle protrudes almost horizontally in the direction in which the knitting needles 6 are arranged from a vertically intermediate position between the knitting needles 6 and the jack 9, and passes between the other adjacent knitting needles 6a. An auxiliary leg portion 16 is provided which is connected to the upper side of the main body 13.

This auxiliary leg portion 16 protrudes in the direction in which the knitting needles are arranged.
5 below.

Between the auxiliary leg portion 16 and the selection operation piece 14, both 14
．． An insertion hole 17 is provided through which the knitting needle 6 can be freely inserted.

Any one of the plurality of selection actuating pieces 14 can be moved to the actuating position of FIG. 4 using any suitable device known in the art.

In the example shown in FIG. 1, the wire metal signal detection rod 25 is moved to two positions (up and down) depending on the presence or absence of the signal hole in the pattern card 24, and only the signal detection rod 25 that has been moved to the upper position shown in the figure is placed above the needle bed 1 of the carriage 31. The cam body 26 rotates in relation to the sliding movement of the cam body 26, and the operating rod 27, which is separately connected to each selection action piece 14, swings about the support plate 19 as a fulcrum, and the selection member 12 is pulled along with the swing. The structure is such that the jack 9 is moved to the operating position shown in FIG. 4 against the elasticity of the spring 18, and during this movement, the jack 9 is sequentially pushed rearward by the carriage 31, but as shown in the figure, the jack 9 is pushed backwards. Since the jack 9 in contact with the top of the carriage 31 cannot lower its rear end against the floating spring 11, it cannot go under the lower surface of the movement restraining member 32 provided on the rear side of the carriage 31, and the lower surface of the movement restraining member 32 The jack 9, which is free to descend due to the selective operation piece 14 remaining in the non-operation position, is left below.

Due to this action, jack selection is performed that produces a positional difference between the front and rear jacks 9.

The knitting needles 6 involved in knitting are connected regardless of whether the respective upper rear jack 9 touches the support ramp 15, i.e. regardless of whether the selection member 12 moves into the active position or remains in the non-active position. It freely passes through the insertion hole 17 formed by the selection action piece 14 and the auxiliary leg part 16 to generate back and forth movement.

In the above, the selection action piece 14 and the auxiliary leg portion 16 are integrally formed with the main body 13 of the flat plate member, and a tension spring 18 is applied to the main body 13 to pull it to the non-action position.

The jack selection device of the present invention has a knitting machine configuration in which a needle bed 1 is provided with a knitting needle 6 and a jack 9 above the rear end of the knitting needle, and a selection member is provided for selecting the jack forward or backward or up or down. , a slender selection action piece 14 extending from the main body 13 of the selection member 12 disposed below the knitting needle below the jack 9 to the jack 9 is provided to selectively act on the jack 9; 14 includes an auxiliary leg 1 that protrudes horizontally between the upper surface of the knitting needle 6 and the lower surface of the jack 9, descends downward, and connects to the main body 13.
6, the strength is increased, preventing breakage and distortion, and increasing durability.

Furthermore, since an insertion hole 17 is provided between the selection action piece 14 and the auxiliary leg 16 through which the knitting needle can be freely inserted, the selection member 1
2 is provided below the knitting needles 6, the construction can be such that the individual movement of the knitting needles 6 is not supported at all.

In addition, in the illustrated embodiment, the main body 13 of the selection member 12, the selection action piece 14, and the auxiliary leg 16 are integrally formed by a flat plate member, so that a large number of them are stacked one on top of the other, and each has its own lateral movement effect. can be generated freely.
