The jacquard device is used for positioning a large number of needles provided in a river lace machine, a loom or the like, and determining a product pattern or the like. Therefore, in this apparatus, it is necessary that the selection hook selection operation can be performed continuously and accurately.
In particular, the select hook is pulled to a predetermined position against the urging force of the needle in the engaged state in which the needle is engaged. Required.

  However, in the conventional electronic jacquard, the selection hook is supported by a holding pin provided upright on the cassette body, and the holding pin is made of the same material as the cassette body. Since it was made of a certain resin, there was a problem that the holding pin was erected, a crack or the like was generated at the root portion, and the original function as a support pin could not be exhibited.

  As for the tip shape of the select hook, the tip surface of the conventional select hook is a surface that goes straight in the longitudinal direction of the needle, so that the swing of the select hook is performed with the tip of the needle hitting the tip of the select hook. It was supposed to act to hinder movement.

  The object of the present invention has been made in view of the above-mentioned problems, and the object of the present invention is to enable stable needle selection operation over a long period of time in an electronic jacquard device, and the tip of the needle is a select hook. An electronic jacquard device and an electronic jacquard cassette that can ensure a stable operation of the select hook even in a state where it hits the tip are provided.

The characteristic configuration of the electronic jacquard device provided with a reciprocating mechanism for reciprocating the jacquard body in the longitudinal direction of the needle is as follows:
The holding pin and the cassette main body are configured as separate bodies, and the holding pin is supported from the holding plate.

In this electronic jacquard device, the holding pin that holds the select hook is conventionally supported by a holding plate that holds and fixes the cassette body and is fixedly held by the jacquard body that is reciprocated in a predetermined direction. As a result, the rocking fulcrum of the select hook is formed while being directly supported from the holding plate.
Moreover, since the holding pins are separated from the cassette body, the holding pins themselves can be made strong and robust.
Therefore, in the electronic jacquard apparatus, a stable needle selection operation can be secured for a long period of time.

  Further, in the above configuration, the holding plate is positioned on one side in the thickness direction of the cassette body, a cover plate is provided on the other side in the thickness direction of the cassette body, and the holding pins are connected to both the holding plate and the cover plate. It is preferable to adopt a configuration supported from the above.

In the non-engagement posture, it is preferable to provide a cassette-side stopper portion that contacts the hook-side stopper portion and stops further swinging of the select hook.
In this configuration, the swing of the select hook is stopped by the contact of both stopper portions, and the non-engagement posture of the select hook can be determined in relation to the cassette body.
Accordingly, not only the engagement with the needle but also the non-engagement posture of the select hook can be ensured, and a stable operation of the select hook, that is, a needle selection operation can be performed.

Furthermore, the needle is provided with an engagement hole into which the hook portion provided at the tip of the select hook enters and engages,
It is preferable that a disengagement guide portion for guiding the select hook from the engaged posture to the non-engaged posture is provided on the proximal end side of the engaging hole by contacting with the select hook.

In the jacquard device, with the select hook engaged with the needle, the jacquard body reciprocates in the longitudinal direction of the needle, and the needle biased in a specific direction is resisted against this biasing force. Pulling action.
At this time, the hook portion provided at the distal end of the select hook engages with the surface on the jacquard main body side, which is the distal end side, in the engagement hole provided in the needle.

Now, when the select hook further moves to the proximal end side of the needle, a state occurs in which the distal end of the select hook comes into contact with the separation guide portion provided on the proximal end side of the needle. When the select hook and the needle come into contact with each other, the separation guide unit according to the present application guides the select hook from the engaged posture to the non-engaged posture.
As a result, the engagement and disengagement of the select hook can be performed reliably and easily, and a stable operation can be ensured.
