Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cross needle control device in a jiaquard mechanism. Conventionally, the jiacard machine lowers the dropper needle corresponding to the perforation pattern of the patterned paper, and sequentially interlocks the subsequent mechanisms.Finally, while sorting the openings of the warp threads of the loom, a pattern is created according to the perforation pattern of the patterned paper. It was used as a control mechanism for weaving. However, when changing the weaving pattern, it is necessary to change the pattern paper, which is a complicated process, and when trial weaving various patterns, it takes a considerable amount of time from the punching of the pattern paper to the actual completion of weaving. It took a long time. For this reason, in recent years, a method has been proposed in which the control mechanism of the dropper needle using a pattern paper is used to transmit electrical signals from a magnetic tape using a computer, thereby speeding up the production of textile patterns.

When installing a computer-based control mechanism on a conventional jiaquard machine, the inventors of the present invention conducted extensive research into a mechanism that could be installed within the space of the existing loom and also allowed the use of conventional patterned paper. This invention was developed, and the gist of the invention is to operate a dropper needle via an electric signal via an lenoid, and to operate a cross needle by raising and lowering a poker connected to the dropper needle. In the Jia card mechanism, a selector box housing a dropper needle and a poker is provided at a position where the tip of the poker faces one end of the horizontal needle, and a pusher is located opposite the other end of the horizontal needle. This invention relates to a cross needle control device for a jia card mechanism, which is provided at a position so that the warp needles can be selectively dropped by pressing the cross needles as the pusher moves forward to correspond to the poker moving up and down.

Hereinafter, a detailed explanation will be given according to the drawings.

The figure shows a longitudinal sectional side view of the main parts of the horizontal needle control device of the present invention, in which a pusher 1 and a selector box 2 are provided with a horizontal needle 3 sandwiched therebetween. The selector box 2 includes a dropper needle 5 that moves up and down via a solenoid 4 in response to a signal from a computer (not shown).
A poker 6 connected to the dropper needle 5 is housed, each of the pokers 6 is located on an extension line of the respective horizontal needle, and when the horizontal needle 3 moves to the right, the poker 6 rises. The time is provided so that the tip of the horizontal hand 3 and the tip of the poker 6 do not coincide, but can only coincide when they are descending (not ascending). The pusher 1 operates in accordance with the pitch of the dropper needle to move up and down, and the horizontal needle 3 is moved by the plunger 7 each time the dropper needle goes up and down.
is pressed to move the horizontal needles corresponding to the rising poker 6 to the right, selectively drop the warp needles 8, and open the loom corresponding to the warp needles that are not allowed to fall. In this case, the plunger spring 9 is stronger than the horizontal needle return spring 10 provided on the horizontal needle 3, and the pressure of the pusher 1 causes the horizontal needle to move to the right while contracting the return spring 10. , the meridian needle 8 is dropped and returns to its original position at the same time as the pusher 1 moves to the left (retreats). Also, if the solenoid 4 is not energized, the dropper needle 5 will not rise, so the tip of the horizontal needle 3 and the poker 6
If the pusher 1 moves to the right and the tip of the needle 3 is located on the same line, even if the plunger 7 pushes the horizontal needle, it is stopped by the poker 6 and does not operate, and the horizontal needle 3 moves to the plunger 7 without changing its position. Only the provided spring 9 is contracted to maintain the warp needle 8 as it is, and the loom corresponding to the warp needle is opened.

As mentioned above, in incorporating a computer system into the Jacquard mechanism, the present invention is to install a selector box including a solenoid dropper needle, poker, etc. connected to the computer at one end of the Jacquard machine, and to insert a pusher at the other end with a horizontal needle in between. This relates to a new cross needle control device that is equipped with It can be easily changed by retracting it outward, removing the pusher, and installing a pattern paper cylinder, and it does not require large-scale equipment, and can be used as both a pattern paper type card and a computer-controlled card. It has great effects, such as being able to use them separately or in combination.
