[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lateral needle control device for a jacquard machine, which electromagnetically controls a lateral needle based on an electric signal according to a woven pattern.

[0002]

[Prior art]

 As a lateral needle control device of a jacquard machine, for example, Japanese Patent Publication No. 60-36493 and Japanese Patent Laid-Open No. 03-260133 disclose a movable table provided at one end of the horizontal needle and a movable table for weaving motion. A reciprocating device that moves in and out of the horizontal needle in conjunction with each other is pivotally attached to the movable table in a horizontally swingable manner corresponding to each horizontal needle. An electromagnetic actuating body that takes a first swinging posture that can substantially engage the lateral needle on the moving side and a second swinging posture that does not substantially engage the lateral needle on the other swinging side; , A magnetic pole applying device provided on the movable table and comprising permanent magnets for arranging different polar magnetic poles on each swing side of each electromagnetic actuation body, and each electromagnetic actuation body is excited by an electric signal according to the fabric pattern Together with the signal that generates a magnetic pole with the polarity corresponding to the electrical signal at the swing end Discloses those composed of a raw device, also the pole imparting device that was good reforming is disclosed in Japanese Patent real-Open No. 4-7680.

In these devices, each electromagnetic actuating body moves in a first swinging posture or by a repulsive action between a magnetic pole generated at a swing end according to a woven handle and each magnetic pole given in advance by a magnetic pole applying device. In the second swinging posture, in the former case, the horizontal needle is pushed by the electromagnetic actuating body when the movable table approaches and the vertical needle crossing it is in a state in which it cannot be linked with the knife. In the latter case, When the movable table approaches and moves, the horizontal needle is held in its original position without being pushed, and the vertical needle that intersects with it moves upward in conjunction with the knife.

By the way, in order to give an electric signal from the signal generator to each of the electromagnetic actuators, a terminal plate provided on the movable body or the like and an electromagnetic coil on each electromagnetic actuator are connected by a flexible electric wire. However, the wire is easily broken by repeated swings of the electromagnetic actuator, and in order to prevent this, if the diameter and material of the wire are changed to increase the strength, the electromagnetic actuator will not swing freely. There was a problem that it was disturbed and a malfunction occurred.

[0005]

[Problems to be solved by the device]

 An object of the present invention is to provide a lateral needle control device for a jacquard machine, which is excellent in strength and has wiring to each electromagnetic actuator that does not hinder the oscillation of the electromagnetic actuator.

[0006]

[Means for Solving the Problems]

 A lateral needle control device for a jacquard machine according to the present invention comprises a movable table provided at one end of the lateral needle and a reciprocating device for moving the movable table toward and away from the lateral needle in conjunction with weaving movement. And a first end which is pivotally attached to the movable base so as to be horizontally swingable corresponding to each lateral needle, and whose swing end can substantially engage with the lateral needle on one swing side when the movable base approaches and moves. An electromagnetic actuating body that takes a swinging posture and has a second swinging posture that is substantially unengageable with the lateral needle on the other swinging side, and a movable base or a terminal plate provided on a member integrated therewith. , The wiring that connects the terminal plate and the electromagnetic coil on each electromagnetic actuator, the magnetic pole applying device that arranges the magnetic poles of different polarities on each swing side of each electromagnetic actuator, and the terminal plate and the wiring. Each electromagnetic actuating body is excited by an electric signal corresponding to the weave pattern, and the swing end is magnetized with a polarity corresponding to the electric signal. In horizontal needle control device for jacquard machine comprising a signal generating device for generating, the wiring is characterized in that it consists of a flexible printed wiring sheet.

As the reciprocating device, for example, a known battan mechanism can be adopted. If necessary, an intermediate member that contributes to the transmission of both electromagnetic actuating members and each horizontal needle may be interposed, and the swinging side of each electromagnetic actuating member may be connected to each swinging side of each electromagnetic actuating member. A stopper member for defining the moving range may be provided, and a magnetic shield member may be provided between each electromagnetic actuating body and another electromagnetic actuating body adjacent vertically and laterally. .

It is preferable to employ a configuration provided with a device.

[0009]

[Action]

 In the above structure, the magnetic pole imparting device imparts an S pole to one swing side and an N pole to the other swing side of each electromagnetic actuator.

When an electric signal corresponding to the weave pattern is input from the signal generator to each electromagnetic actuating body via the terminal board and the flexible printed wiring sheet, each electromagnetic actuating body is excited and the swing end is also excited. Since an N-pole or S-pole magnetic pole is generated in each of the magnetic poles, each electromagnetic actuating body swings to each rocking side by attraction and repulsion between the magnetic pole generated at the rocking end and each magnetic pole given from the magnetic pole applying device. At the same time, it takes the first swinging posture or the second swinging posture.

When the movable table is moved closer to a predetermined position toward the lateral needle by the reciprocating device, the lateral needle corresponding to the electromagnetic actuating body in the first swinging posture is directly or in contact with the electromagnetic actuating body. The lateral needle corresponding to the electromagnetic actuating member that is pushed by the mechanical engagement and takes the second swinging posture is held in the original position without being engaged with the electromagnetic actuating member, and therefore each lateral needle is It will be selectively pushed according to the woven pattern. After the control of each lateral needle, the movable base is moved away from the lateral needle to the original position by the reciprocating device, and each electromagnetic actuating body waits for the next electric signal input corresponding to the fabric pattern.

In the above apparatus, in which the electromagnetic actuators and the magnetic pole imparting device on each column are provided on the movable table via the substrate, the electromagnetic actuators and the magnetic pole imparting device having each substrate on the column are mounted. It functions as a package or a cassette, and each electromagnetic actuator and magnetic pole applying device is attached to and detached from the movable table on a substrate basis.
