Description

Electronic Double Action Jacquard Shedding Device

technical field

The present invention relates to a high-speed electronic double-action jacquard shedding device, in particular to an electronic double-action jacquard shedding device with a moving device capable of moving a vertical hook when an electric signal is applied and A hook is arranged on the hook at a predetermined distance.

Background technique

Generally, the jacquard shedding device of a mechanical jacquard loom consists of the following: a fountain for hooking a paper with punched holes formed according to the required fabric structure; The moving link lifts the lifting knife; a horizontal needle driven to be inserted into the hole in the pattern plate hooked on the flower tube; promote. In operation, when the pattern plate rotates intermittently with the rotation of the fountain tube, the front end of the horizontal needle passes through the punched hole on the pattern plate and is inserted into the groove or hole formed on the outer peripheral surface of the fountain tube, so the vertical hook follows The lifting of the lifting knife is promoted, so that the warp yarn hooked on the carabiner forms a shed, and the shuttle is used to provide the weft yarn through the shed, so the fabric of the desired pattern can be woven. Unlike a body driving loom, the Jacquard shedding device utilizes the actuation of each carabiner, thereby allowing weaving of a patterned fabric with very small complete weaves. However, a problem with mechanical Jacquard shedding devices is that the weaving speed is very low.

In order to solve the problems of the above-mentioned mechanical jacquard shedding device, the applicant's Korean Patent Publication No. 95-13494 as an instant invention discloses a known conventional electronic reciprocating jacquard shedding device .

The known conventional electronic double action Jacquard machine utilizes an electromagnetic unit to control the movement of the carabiners. The electromagnetic unit is adapted to control the movement of the hook through the combination of an electromagnet and a permanent magnet, the magnetic force of which varies according to the electrical signal received from the opening control device. The electromagnet is made by inserting a bobbin on which a coil is wound into a core, and then it is fixed on a frame. The hook on which the permanent magnet is formed rotates according to the magnetization of the electromagnet. Therefore, the end of the hook is inserted into the hook hole of the carabiner, thereby controlling the movement of the carabiner.

However, a problem with this known conventional electronic double-action Jacquard device is that it may malfunction when operating at high speeds. Therefore, there is a need to improve the reliability of its operation.

Summary of the invention

It is therefore an object of the present invention to provide an electronic reciprocating jacquard machine shedding device capable of improving its operational reliability.

In order to achieve this and other objects of the present invention, the present invention provides an electronic double-action jacquard shedding device on a textile loom, which controls the movement of the carabiner by separating a plurality of warp yarns to form a shed. The double-action jacquard machine opening device includes: a carabiner manipulator, which has a hook suitable for being installed on the carabiner so as to control the relative position with the carabiner, and the caravan manipulator is assembled to pass through A fixed pin on the frame and a permanent magnet formed on both sides of the pin on the hook manipulator rotate at a predetermined angle; The electromagnet core is fixed at both ends by pins on the frame so that it is arranged in a position opposite to the permanent magnet on the carabiner manipulator.

If the electromagnet is magnetized by applying an electrical signal, it repels and attracts the permanent magnet of the carabiner so that the carabiner can be turned toward one side. When the carabiner manipulator turns, the hook formed on the carabiner manipulator is combined with or separated from the carabiner, thereby controlling the movement of the carabiner relative to the carabiner manipulator, so that the warp yarn changes position by using the rise/fall of the carabiner , thus forming a shed.

In this case, a spring is installed between one end of the carabiner manipulator and the frame, thereby applying elastic force to the carabiner manipulator in a predetermined direction, and electromagnets are respectively formed at opposite ends of the electromagnet core. An integral support member is fixed to the frame by the combination of pins and pin holes formed in the support member.

Both ends of the electromagnet core and the permanent magnet formed on the hook manipulator are arranged so as not to contact each other. This way the magnet is inserted deeper than the surface of the carabiner manipulator or the support part is more protruding than the solenoid core.

Preferred version of the present invention

Now, the structure of the shedding device of the electronic double-action jacquard machine according to the present invention will be described hereinafter with reference to the accompanying drawings.

In the textile loom, the electronic double-action jacquard machine shedding device of the present invention separates a plurality of warp yarns to form a shed, and the device includes a carabiner manipulator 101 and an electromagnet.

The carabiner manipulator 101 has a hook 103 that is assembled with the carabiner 120 to control the relative position of the carabiner 120. The carabiner manipulator 101 is assembled with a frame using a fixing pin 102, so that it can be fixed at a predetermined angle. turn around. Based on the fixing pin 102, the carabiner manipulator 101 forms permanent magnets 104, 105 on both sides thereof. The permanent magnet is formed such that a corresponding portion of the carabiner manipulator body can be magnetized or a permanent magnet block can be inserted into the carabiner manipulator body. When determining the magnetic force direction of the permanent magnet, if one side magnet forms an 'N' pole on its surface, the other side magnet also forms an 'N' pole on its surface. That is, these permanent magnets form the same magnetic poles as each other on their surfaces. This is because if the electromagnet is magnetized, one end of the electromagnet core forms an 'N' pole and the other an 'S' pole, causing the carabiner to pull on one end and repel on the other.

The electromagnet is formed by winding a coil 110 around a "匚" shaped electromagnet core 109. Both ends of the electromagnet core are designed to be opposite to the permanent magnets of the hook manipulator 101 and assembled with the frame 130 through pins 108 . Support members 107 and 111 integral with the electromagnet core are formed at both ends of the electromagnet core and include a pin hole thereon so that they are fixed by the pins 108 and 112 on the frame 130 . The arrangement that the electromagnet core is in direct contact with the permanent magnet is feasible, but the supporting parts 107 and 111 are made to protrude a little more than the electromagnet core so that the permanent magnet formed on the carabiner manipulator does not directly contact the electromagnet core. This arrangement is ideal. If both ends of the electromagnet core are in direct contact with the permanent magnets formed on the carabiner, it is difficult to separate the electromagnet core from the permanent magnets due to the strong pulling force between the magnets. Further, if the electromagnet core is attached directly to the pole, the pole will exert a strong pulling force. However, if there is a gap between the pole and the magnetized material, the magnet will only exhibit weak magnetic force. Therefore, it is desirable that the permanent magnet is inserted deeper than the surface of the hook manipulator or that the ends of the support members 107 and 111 are formed to protrude more than the end of the electromagnet core so that the electromagnet core is not directly connected to the permanent magnet. touch.

If an electrical signal is applied to the coil 110 of the electromagnet, the electromagnet is magnetized, thereby repelling the permanent magnet on one side of the carabiner manipulator and attracting the permanent magnet on the other side thereof. Therefore, this vertical hook manipulator 101 turns to one side direction, and when vertical hook manipulator 101 turns around, the hook 103 formed on the vertical hook manipulator 101 and vertical hook 120 combine/separate, thereby control vertical hook 120 relative to Relative movement of carabiner manipulator 101 .

A spring 106 is installed between an end of the carabiner manipulator 101 and the frame, so that the caravan manipulator 101 turns in a predetermined direction under the action of elastic force and is in its initial position (shown by the dashed circle 'A' in Fig. 1 Show). In this case, if an electric signal is applied to the coil 110 of the electromagnet, the electromagnet is magnetized. The magnetization direction of the electromagnet is determined such that the electromagnet attracts the permanent magnet disposed on the side on which the spring 106 is mounted and repels the permanent magnet on the side opposite to the side on which the spring is mounted. Therefore, the carabiner manipulator 101 removes the force of the spring 106 and turns in the opposite direction (as shown by the dashed circle 'B' in Figure 1 ) to a normal position, so that the hook of the carabiner manipulator is in contact with the groove 121 of the carabiner 120. or 122 to control the relative movement of the carabiner 120 . Then, if the electrical signal disappears, the electromagnet demagnetizes and the hook manipulator 101 returns to its initial position (position 'A') under the urging force of the spring 106.

Therefore, if an electrical signal is sent from the jacquard machine control unit, the upward and downward movement of the carabiner 120 is controlled by the driving of the lifting knife 140, thereby forming a shed.

The carabiner 120-2 is lifted by the lifting knife 140, and if an electrical signal is applied to the electromagnet, the carabiner manipulator becomes state 'B' under the magnetic force of the electromagnet. Like this, the hook 103 of the carabiner manipulator cooperates with the groove 122 of the carabiner, and even if the lifting knife descends, the caravan 120-2 does not descend and remains in the above-mentioned state. If no electrical signal is applied to the electromagnet, the manipulator changes to state 'A' due to the magnetic force of the electromagnet. The hook 103 of the carabiner manipulator no longer cooperates with the groove 121 of the carabiner like this, and if the lifting knife descends, the carabiner 120-1 also descends. At this time, the two lifting knives are adjusted to move up and down in directions opposite to each other, so that the shedding operation of the jacquard machine is performed in a reciprocating manner and at a high speed. If the loom is run at a faster speed, the gib moves rapidly and makes the repetitive motion of the carabiner very rapid. In this case, the power applied to the hook is generated by the synergy of the magnetic force of the electromagnet, the magnetic force of the permanent magnet and the elastic force of the spring, which allows the hook manipulator to move at a very high speed and in a more reliable manner, This enables errors to be significantly reduced.

It can be clearly seen from the above that the opening device of the electronic double-action jacquard machine can control the movement of the hook manipulator through the synergistic effect of the electromagnet magnetic force, permanent magnet magnetic force and spring force, so that the carabiner manipulator can be used at high speed and more Reliable way to move, which makes the reliability of operation has been significantly improved.
