Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a lateral needle control device for a jacquard machine.

[Conventional technology]

As a horizontal needle control device, it is well known that a horizontal needle is selectively moved depending on the presence or absence of perforation in a pattern paper, and a vertical needle that intersects with a stationary horizontal needle is hooked on a knife and raised. However, this device has a problem that a large amount of pattern paper is required when weaving a high-quality pattern fabric.

On the other hand, for example, Japanese Examined Patent Publication No. S60-36493 discloses a horizontal needle control device which electromagnetically controls the horizontal needle based on a woven pattern signal instead of the pattern paper. Although this solves the above problem to some extent, the stopper is electromagnetically oscillated in response to a textile pattern signal with respect to a pivot perpendicular to the lateral needle, thereby relating to the position of engagement with the lateral needle. Since it is configured to be selectively placed in a position that does not match, there are problems that the stopper is easily deformed or damaged during use due to the rocking structure of the stopper, and it cannot sufficiently cope with high-speed rotation of the loom. It was

[Problems to be solved by the invention]

The object of the present invention is to control the horizontal needle electromagnetically based on the woven pattern signal instead of the pattern paper, and also to have excellent strength and reliability, and to sufficiently support the high speed rotation of the loom. It is to provide a control device.

[Technical means for solving problems]

The above object can be achieved by the present invention. That is, the lateral needle control device of the jacquard machine according to the present invention is (a)
A pusher provided adjacent to the end of the horizontal needle so as to be capable of reciprocating in the axial direction of the horizontal needle, (b) Corresponding to each horizontal needle, rotatably mounted on the pusher parallel to the horizontal needle. Rotating shafts, (c) stoppers that are provided to project from each rotating shaft and that are selectively arranged at the blocking position facing the end of the horizontal needle or the open position not facing, depending on the rotation angle of the rotating shaft, ( d) An electromagnetic coil provided on each rotary shaft body and selectively excited in accordance with the texture signal, (e) an adsorbent body protruding from each rotary shaft body, and selectively magnetized by the electromagnetic coil, f) A pusher is provided so as to sandwich each adsorbent with opposite magnetic poles that face each other, and the adsorbent is selectively attracted to one of the magnetic poles according to a textile pattern signal, and the rotary shaft is rotated in one direction to stop. The permanent magnet for selectively arranging the switch in the shut-off position or the open position, (g) a reciprocating motion device for driving the pusher, and (h) an electromagnetic coil signal for the weave pattern signal. Made from the signal generating device to be applied to, it is characterized in that so as to selectively push controlled by horizontal needles and pusher facing the arranged stopper blocking position in response to the woven signal.

[Action]

In the above configuration, when a predetermined pattern signal is input to each electromagnetic coil from the signal generator, each electromagnetic coil is selectively excited and each adsorbent is selectively magnetized. The magnetic pole is attracted to one of the magnetic poles in accordance with the weave pattern signal and the rotary shaft is rotated around the axis in one direction together with the stopper to selectively dispose the stopper at the blocking position or the open position.

Subsequently, when the pusher is moved or swung to a predetermined position toward each lateral needle by the reciprocating device, all the rotating shafts move integrally with the electromagnetic coil and the permanent magnet. In that case, the horizontal needle corresponding to the rotary shaft body whose stopper is in the blocking position is engaged with the rotary shaft body through the stopper, and the horizontal needle corresponding to the rotary shaft body whose stopper is in the open position is the rotary shaft body. Since it is left without being engaged with, each lateral needle is selectively pushed according to the woven pattern signal. The movement of the vertical needle due to the above-mentioned push control of the horizontal needle and other various movements of the jacquard machine are as conventionally known, and the battan mechanism in the conventional jacquard machine is adopted as the reciprocating device in the present invention. May be.

Finally, when the moved pusher is returned to its original position by the reciprocating device, all the rotating shafts are integrally restored with the electromagnetic coil and the permanent magnet, and each electromagnetic coil receives the next texture signal. Wait for input. Needless to say, the lateral needle that has been pushed first also returns to its original position due to the repulsive force of the spring mechanism, etc., in response to the return movement of the pusher body.

[Embodiment 1] FIG. 1 is a plan view of an essential part of an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line II in FIG.

In the figure, a pusher (1) is provided adjacent to an end of a horizontal needle (2) (only three of which are shown) so as to reciprocate in the axial direction of the horizontal needle (2). (3) (Only two are shown) can be rotated by the pusher (1) via the bearings (4) at both ends, corresponding to each horizontal needle (2) and parallel to the horizontal needle (2). It is suspended. The pusher (1) is driven by a reciprocating device (5).

A stopper (6) is provided so as to project in the radial direction in the vicinity of one end of each rotary shaft body (3), and each stopper (6) corresponds to the horizontal needle (2) depending on the rotation angle of the rotary shaft body (3). It is selectively placed at a blocking position (P) facing the end or an open position (Q) not facing the end.

Further, the electromagnetic coil (7) is wound around each rotary shaft body (3), each electromagnetic coil (7) is selectively excited according to the fabric pattern signal, and the fabric pattern signal is generated by the signal generator (8). ) Is applied to each electromagnetic coil (7).

Further, the adsorbents (9) are provided so as to protrude in the radial direction near the other end of each rotary shaft body (3), and each adsorbent (9) is selectively magnetized by the electromagnetic coil (7).

A permanent magnet (10) is provided on the pusher body (1) so as to sandwich each adsorbent body (9) with the N pole and the S pole facing each other, and each permanent magnet (10) has a woven pattern of the adsorbent body (9). S depending on the signal
The rotary shaft body (3) is rotated in one direction together with the stopper (6) while being selectively attracted to the pole or the N pole. Each stopper (6) is arranged in the blocking position (P) when the adsorbent (9) is attracted to the S pole, and is placed in the open position (Q) when the adsorbent (9) is attracted to the N pole. Will be placed.

In the above configuration, when a predetermined pattern signal is input from the signal generator (8) to each electromagnetic coil (7), each electromagnetic coil (7) is selectively excited and each adsorbent (9) is also excited.
Are selectively magnetized, so that each permanent magnet (10) attracts the adsorbent (9) to the S pole or the N pole according to the textile pattern signal and rotates the rotary shaft body (3) in one direction to stop the stopper. (6) is selectively placed at the shutoff position (P) or the open position (Q).

Then, when the pusher (1) is moved or swung to a predetermined position toward each lateral needle (2) by the reciprocating device (5),
All the rotating shafts (3) move integrally with the electromagnetic coil (7), the permanent magnet (10) and the like. In that case, the horizontal needle (2) corresponding to the rotary shaft body (3) in which the stopper (6) is in the shut-off position (P) is connected to the rotary shaft body (3) via the stopper (6).
Since the lateral needle (2) which is engaged with the rotary shaft body (3) whose stopper (6) is in the open position (Q) and which corresponds to the rotary shaft body (3) is left unengaged with the rotary shaft body (3), Each horizontal needle (2) is selectively pushed according to the pattern signal.
