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 is 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, there are many steps from perforating the pattern paper to actually completing the weaving.
It took quite a long time. For this reason, in recent years a method has been proposed in which a control mechanism based on patterned paper is used to transmit electrical signals from a magnetic tape using a computer, thereby speeding up the production of textile patterns.

This invention was developed as a result of careful consideration of a mechanism that could be installed within the space of the existing loom when installing a computer-based control mechanism on a conventional jiaquard machine. , these problems were solved and a more compact control mechanism was created. That is, the gist of the invention is to operate a dropper needle via a solenoid using an electric signal, and to operate a horizontal needle by raising and lowering a poker slidably engaged with the dropper needle. In the Jia card mechanism, a selector box housing a dropper needle and a poker is provided at a position where one end of the poker in the lowered position faces one end of the horizontal needle, and a grid having a poker receiving plate is attached to the lower front part. A pusher is provided at a position where the other end of the poker in the lowered position faces the grid, and the pusher is made to repeatedly perform forward movement, upward movement, and downward movement in the above order, and the forward movement presses the horizontal needle, causing the upward movement. Sometimes, all the pokers are temporarily lifted by the poker receiving plate of the grid, and at that time, a selection signal is sent to the solenoid corresponding to the dropper needle that supports the poker, thereby suctioning and holding the specified poker in that position, and removing the other pokers. This invention relates to a transverse needle control device in a jacquard mechanism, which is capable of selectively dropping warp needles by dropping them.

The present invention will be described in detail below with reference to the drawings. FIG. 1 is a partially longitudinal side view showing an embodiment of the present invention, in which the horizontal needle 6 presses one end of the poker 2 by the return spring 14. and a meridian needle (not shown) is involved. A selector box 10 has a dropper needle 1 which is raised and lowered via a solenoid 9 in response to a signal from a computer (not shown). A poker 2 which is horizontally slidably engaged with the dropper needle 1 is housed, and each poker 2 is connected to a respective horizontal needle 6. When the pusher 3 moves forward (moves to the right) and the poker 2 is rising, the tip of the pusher grid 4, 4', 4'' provided at the front of the pusher 3 and the poker 2 It is provided in such a way that it does not match with the tip of the tip, and can only match when it is descending (not rising).
When the pusher 3 moves backward (moves to the left), it first moves upward, but at this time, one end of the poker 2 is moved by the pusher grid lower plate 5, 5', 5'' using the poker support plate 15 as a fulcrum. At this time, the armature 16 at the top tip of the dropper needle is held against the solenoid holder 11.
It comes into contact with the suction surface of the solenoid 9 attached to the solenoid 9. Therefore, when a selection signal is issued from the computer, those with a signal are attracted and held by the solenoid 9 at that position. The pusher 3 continues to retreat (move left), and as a result, the poker 2 separates from the pusher grid lower plate 5, 5', 5'', and if there is no signal, the poker 2 falls, and the poker support plate 12 It stops at the lower end of the hole and faces the pusher grids 4, 4', 4''. The pusher 3 moves backward (moves to the left) while moving downward, and ends the retreat (moves to the left) at the starting height. Once again, Pushya 3 moves forward (to the right) and falls down to confront the enemy (no signal).
Press Poker 2. As a result, the horizontal needle 6 moves forward (moves to the right) while contracting the return spring 14.
By dropping the warp needles (not shown) entangled with the horizontal needles 6, the loom can finally be opened and a predetermined woven pattern can be obtained.

As explained above, according to the device of the present invention, the stroke torque of the solenoid is not required by mechanically lifting the dropper needle, and the solenoid can be made smaller because it only needs to be held with a small suction force. Since the power consumption is low and the device is very compact, there is no need for extensive modification of the conventional Jia card machine, making it economical.
