ELECTRONIC DOUBLE LIFT JACQUARD SHEDDING DEVICE
DESCRIPTION Technical Field The present invention relates 10 a high-speed electronic double lift jacquard shedding device and more particular!;., to an electronic double lift jacquard shedding device having a moving means capable of moving a hook on which a hooker is formed by a predetermined distance, if an electric signal is applied.
Background of Invention
Generally, a jacquard shedding device of a mechanical jacquard loom is composed of a cylinder for hooking paper on which a punched hole is formed according to a necessary woven structure, a knife adapted to be lifted by a rod operating according to the driving of the cylinder, a needle driven ;o be inserted into the hole of the paper hooked on the cylinder and a hook adapted to be lifted according to the driving of the needle and the knife. In operation, when the paper is ir.termittently rotated by the rotation of the cylinder, the front end of the needle is inserted into a groove or hole formed on the outer peripheral surface of the cylinder through the hc!e punched in the paper and thereby, the hook is lifted as the knife is lifted, such that a warp hooked on the hook is shed and a weft is supplied through the opened shedding by means of a shuttle, thereby weaving a desired pattern fabric. The jacquard shedding device utilizes the driving of each hook, unlike a body driving loom, thereby weaving the fabric having a pattern where complete weaves are small. However, the mechanical jacquard shedding device arises a problem that a
weaving speed is substantially low. To overcome the above-discussed problem in the mechanical jacquard shedding device, a conventionally known electronic double lift jacquard shedding device is disclosed in Korean Patent Publication No 95- 13494 issued to the same applicant as the instant in\ ention The conventionally known electronic double lift jacquard device utilizes an electromagnet unit for controlling the movement of the hook The electromagnet unit is adapted to control the movement of a hooker by the combination of an electromagnet whose magnetism is varied depending upon an electric signal received from a shedding control deuce and a permanent magnet The electromagnet is made by inserting a bobbin on which a coil is wound into a core and then, it is secured on a frame The hooker on which the permanent magnet is formed is rotated in accordance with the magnetization of the electromagnet As a consequence, the end of the hooker is inserted into a hooking hole of the hook, thereby controlling the movement of the hook
The conventionally known electronic double lift jacquard device arises, however, a problem that it may generate malfunctions, while operating at a high speed Therefore, there is a need for the improvement of the reliability of the operation
Disclosure of Invention
It is, therefore, an object of the present invention to provide an electronic double lift jacquard shedding device capable of improving the reliability of the operation thereof
To attain this and other objects of the present invention, there is provided an electronic double lift jacquard shedding device controlling the movement of a hook by dividing a plurality of warps to form the shedding, in a fabric weaving loom, which comprises a hook operator having a hooker adapted to be assembled to the hook to control the relative position to the hook, assembled to be rotated by a predetermined angle by means of a fixed pin on a frame and forming permanent magnets on the both sides

Best Mode for Carrying Out the Invention
Now, an explanation of the construction of an electronic double lift jacquard shedding device according to the present invention will be hereinafter discussed with reference to the accompanying drawings. An electronic double lift jacquard shedding device according to the present invention divides a plurality of warps to form the shedding, in a fabric weaving loom, which comprises a hook operator 101 and an electromagnet.
The hook operator 101 has a hooker 103 that is assembled with a hook 120 to control the relative position to the hook 120, and it is assembled with a frame by means of a fixed pin 102, thereby rotating by a predetermined angle On the basis of the fixed pin 102, the hook operator 101 forms permanent magnets 104, 105 on the both sides thereof The permanent magnet is formed such that the part of the hook operator body may be magnetized or the permanent magnet piece may be inserted into the hook operator body In determining the magnet direction of the permanent magnets, if the one side magnet forms an 'N' pole on the surface thereof, the other side magnet also forms the 'N' pole on the surface thereof That is, the permanent magnets form the same magnetic poles as each other on the surfaces thereof This is because the one end of the electromagnetic core forms the "N" pole, the other end thereof forms an 'S' pole, if the electromagnet is magnetized, such that the hook operator generates a pulling force on the one end thereof and a repulsive force on the other end thereof
The electromagnet is formed by wounding a coil 1 10 on a "tr "-shaped
electromagnetic core 109 The both ends of the electromagnetic core are designed to be opposite to the permanent magnets of the hook operator 101 and assembled by means of a pin 108 with the frame 130 Support parts 107 and 1 1 1 as integral with the electromagnetic core are formed on the both ends of the electromagnetic core and include a pin hole thereon, thereby being fixed by means of pins 108 and 1 12 on the frame 130 The arrangement where the electromagnetic core is in direct contact with the permanent magnets is possible, but the arrangement where the support parts 107 and 1 11 are formed more protruded than the electromagnetic core, such that the permanent magnets formed on the hook operator are not in direct contact with the electromagnetic core, is desirable If the both ends of the electromagnetic core are in direct contact with the permanent magnets formed on the hook operator, it is very difficult to separate the electromagnetic core from the permanent magnets due to a strong pulling force of the magnets In more detail, if the electromagnetic core is directly attached on the magnetic pole, the magnet exerts a strong pulling force However, if a gap between the magnetic pole and the magnetizing material occurs, the magnet exhibits a substantially weak force Therefore, it is desirable that the permanent magnet is inserted deeper than the surface of the hook operator or the end portions of the supporting parts 107 and 111 are formed more protruded than those of the electromagnetic core, such that the electromagnetic core is not in direct contact with the permanent magnets.
If an electric signal is applied to the coil 1 10 of the electromagnet, the electromagnet is magnetized, such that is pushes the one side permanent magnet of the hook operator and pulls the other side permanent magnet thereof. Thereby, the hook operator 101 is rotated in one side direction and as the hook operator 101 rotates, the hooker 103 formed on the hook operator 101 is assembled/disassembled to/from the hook 120, thereby controlling the relative movement of the hook 120 to the hook operator 101 A spring 106 is installed between the one end of the hook operator 101 and the frame, such that the hook operator 101 rotates in a predetermined direction and is in its original position (as indicated by the dotted circle *A in Fig. 1 ) by the application of the spring force. In this case, if the electric signal is applied to the coil 110 of the electromagnet, the electromagnet becomes magnetized. The magnetization direction of the electromagnet is determined such that the electromagnet pulls the permanent magnet disposed on the side where the spring 106 is installed and pushes the permanent magnet on the opposite side to the side where the spring is installed. Hence, the hook operator 101 withdraws the force of the spring 106 and rotates in the opposite direction (as indicated by the dotted circle 'B' in Fig. 1) to a normal position, such that the hooker of the hook operator is assembled to the groove 121 or 122 of the hook 120, thereby controlling the relative movement of the hook 120. Then, if the electric signal disappears, the electromagnet loses its magnetization and the hook operator 101 returns its original position ('the position 'A') by the pushing force of the spring 106
Therefore, if the electric signal is sent from the jacquard control unit, the up and down movement of the hook 120 by the driving of the knife 140 is controlled, thereby forming the shedding.
The hook 120-2 is ascended by the knife 140, and if the electric signal is applied to the electromagnet, the hook operator becomes in the state 'B' by the force of the electromagnet. Thus, the hooker 103 of the hook operator is assembled to the groove 122 of the hook, and even if the knife is descended, the hook 120-2 is not descended and is kept at the above state. If no electric signal is applied to the electromagnet, the operator becomes in the state 'A by the force of the electromagnet Thus, the hooker 103 of the hook operator is not assembled to the groove 121 of the hcok, and if the knife is descended, the hook 120- 1 is also descended At this time, two knives are adapted to move up and down in the opposite direction to each other, such that the jacquard shedding operation is carried out in a double lift manner and at a high speed If the loom operates at a more rapid speed, the knives move rapidly and hence, the repetitive movement of the hook is speedy In this case, the moving force applied to the hook is created by the cooperation of the electromagnet force, the permanent magnet force and the spring force, such that the hook operator can move at a rapid speed and in a more reliable manner, which ensures the remarkable reduction of the generation of errors
As clearly apparent from the foregoing, an electronic double lift jacquard shedding device is capable of controlling the movement of a hook operator by the cooperation of an electromagnet force, a permanent magnet force and a spring force, whereby the hook operator can move at a rapid speed and in a more reliable manner, which ensures the remarkable improvement of the reliability of the operation.
