The present invention ensures the opening state formed by the upper and lower inclined yarns during weaving, thereby reducing the friction between the drum and the repier and making accurate operation. A drive device of a potter is designed to weave a good quality fabric without paying for it.

In detail, a drive box operated by a driving force is installed on one end of the rail located at the top of the loom to set the timing of the drive by the sensor cam connected to the control unit (computer), and operate according to the pattern of the fabric structure. Heukwang group connected by a jack lever to the rope makes weaving the fabric texture correctly without reducing the opening movement up and down while reducing the partial wear and life of parts during the weaving movement. It relates to a drive device of a potter.

Conventional dobbyizers use the falling force of the vertical light group to move vertically or vertically, or they must be installed in an extremely limited space by converting minute movements only mechanically. There was a lot of problems that naturally rotate at a low speed, there was a problem that the quality of the fabric resulting from such a malfunction also drops significantly.

In addition, there is no drawer that can match the speed of the loom, the installation of a low-speed dobby loom on a high-speed loom was very inefficient, and there was a drawback in productivity.

In other words, when the opening is opened and closed and narrowed, the upper slope and the lower slope do not stop at the original position but are slightly narrowed and then reopened. There was no choice but to prevent friction at the drum or the lepier.

The present invention was devised to solve the above-mentioned shortcomings, and the number of parts becomes smaller as the quantity of each part becomes smaller, and the fine movements are electronicized to energize the solenoid from the computer, so that the fabric is formed. To prevent and detect

The above objects and other features and advantages will become more apparent from the embodiments according to the accompanying drawings. Based on the following examples, the subject matter is in no way limited.

1 is a front end of the rail (1) installed on the loom rail support (56). A perspective view of the opening device of the weaving machine with the rear frame (2) (2-1) drive box installed, and the rope 36 having both ends of the upper section of the heald beam group 38 passing through the guide rollers 37 (37-1). Before configuring the drive box. It is connected to the jack lever 34 of the rear frame (2) (2-1), and the frame (2) (2-1) has a camshaft transmission chain gear (41) and chain (42), chain tension gear (43) and Sensor cams 46, 46-1, sensors 45, 45-1, sensor brackets 44, 44-1, and the dial lever jaw 35 provided at the tip of the camshaft 10, 10-1. )

As shown in FIG. 2 to the rear of the rear frame 2-1, the chain 4-1 is hooked to the chain gear 4 of the loom's drive shaft 3 so that the chain gear of the dobby transmission shaft 6 It has a bevel gear box (7) and a dial lever jaw (35-1) to drive the electric bevel gear (8) and the camshaft bevel gear (9) by driving the (5) and dobby transmission shafts (6). Allows the military to transmit power for vertical movement up and down.

In FIG. 3 (a), there are catch levers 11, 11-1 and cams 18, 18-1 for operating the dial lever 30, and a stop catch for stopping the dial lever 30. 50) and four divisions of the spring (51) (52), the solenoid (13-2) group and the jack lever link (32) jack lever (34), that is, the dial lever (30) installed on the top of the dial lever (30). The catch levers 11, 11-1, and jack levers 34 and links 33 form a legion comparable to that of one perfect slope required for fabric organization.

Referring to FIG. 3 (b), the solenoid 13 and the solenoid spring 14, the link 15, the link lever 23, and the return spring which can be selectively moved according to the fabric structure in the catch lever 11 movement. 24, the slider 16 is paired to allow the link 15 to reciprocate from side to side as the solenoid 13 is energized and stopped, and the slewing lever 17 moves the cam as the cam 18 rotates. In (18), the bearing 19, the bearing pin 21, the sling lever 17 and the sling lever return spring 25 are paired so that the sliding lever 17 is centered on the slide lever pin 22. Paired to move left and right, catch 26, catch pin 27, catch spring 28, catch jaw 29 and the dial lever jaw 30 and the catch 26 is hook catch 11 In accordance with the rotation of the cam 18 around the catch lever shaft pin 12 of) the tip of the dial lever 30 forms a pair that can move in the opposite direction of the catch lever 11 movement, catch Server 11 (11-1) group was to take the engaging shoulder formed at the bottom becomes equally divided into two groups dial lever 30.

The operation state of FIG. 1 to FIG. 3 (a) and FIG. 3 (b) is explained in detail as follows.

As shown in FIG. 2, when the loom transmission shaft 3 rotates and the chain gears 4 and 5 are connected with the chain 4-1 to rotate, the dobby transmission shaft 6 rotates. The driven bevel gear 9 in contact with the electric bevel gear 8 is rotated, and the camshaft 10 and the cam 18 are rotated. Subsequently, the camshaft 10-1 is rotated by being transmitted to the camshaft transmission gear 41, the camshaft transmission chain 42, and the chain tension gear 43 coupled to the camshaft 10 shown in FIG. When the sensor cams 46 and 46-1 coupled to the tip of the cam shafts 10 and 10-1 rotate, the sensors 45 and 45-1 inform the controller (not shown) of the rotation angle according to the fabric structure. When the solenoid 13 pin is pulled in the direction of the arrow shown in FIG. 3 (b), the solenoid spring 14 is also pulled in the pin direction while the solenoid shown in FIG. 15 moves in the direction of the arrow, and then the upper end of the slider 16 centered on the slider pin 20 is operated in the opposite direction to the link 15 to engage the recess formed in one end of the sliding lever 17. On the other hand, when the cam 18 rotates around the camshaft 10 and the long diameter of the cam 18 transmits a rotational force to the bearing 19 outer diameter, the force at this time is transmitted to the bearing pin 21, When the rotational force of the cam 18 is transmitted to the catch lever 11 through the sliding lever pin 22 and the slider pin 20 by being bitten by the sliding lever 17 and the slider 16, the upper portion of the catch lever 11 is provided. The catch 26 coupled to the lock lever is caught by the locking jaw of the dial lever 30 and moves in the direction of the arrow. The upper end of the dial lever 30 moves the jack lever 34 shown in FIG. To the imaginary line to achieve an upward incline. When the cam 18 is rotated to a shorter diameter, the heald frame return spring 40 shown in FIG. 1 is the catch lever of FIG. 3 (a). As the return springs 54 and 54-1 are pulled back to their original positions, they form a lower slope.

On the other hand, if the control unit (not shown) is not controlled to energize the solenoid 13 shown in FIG. 3 (b), the link lever 23 and the link 15 are driven by the repulsive force of the solenoid return spring 24. In addition to moving in the direction opposite to the arrow, the upper curved portion of the slider 16 is in the imaginary line position such that the sliding lever 17 and the slider 16 are not engaged. Therefore, even if the rotational force of the cam 18 is transmitted to the outer diameter of the bearing 19, only the sliding lever 17 rotates around the sliding lever pin 22, so that the sliding lever 17 is the sliding lever of FIG. 3 (a). Since only the sliding lever 17 is moved as in 17-1, the catch lever 11 is in its place so that the dial lever 30 is not moved and the first lever heald return spring 40 is the dial lever jaw 35 Pulled up).

In addition, the catch levers 11 and 11-1 are divided into two groups, and the cams 18 and 18-1 are rotated by the chain 42 opposite to the long diameter and the short diameter. There are times when there is a downward slope and the downward slope stays as a downward slope, so when the upward slope should stay, it takes a long time to descend and return to its original position (fall). By configuring the two groups, the descending slope is received again in the middle to raise the speed to shorten the exercise time of the slope. Thus, the springs 28 are positioned so that the catches 26 and 26-1 can be caught by the jaws when the long and short diameters of the cams 18 and 18-1 move the catch levers 11 and 11-1. I stopped it on my chin.

The stop catch 50, the springs 51, 52 and the solenoid 13-2 of FIG. 3 (a) have the hassle of rising again during the descent when the above-mentioned inclined motion is to remain in the upper inclination according to the fabric structure. If the solenoid 13-2 is pulled toward the arrow when the dial lever 30 is positioned on the imaginary line, the stop catch 50 is caught on the chin of the dial lever 30 to prevent movement. Therefore, the slope that continues to rise is exactly lowered only when it is lowered according to the memorized organization of the controller, and the slope that rises stays in place to form a certain opening, and the speed is increased by not performing unnecessary movement (movement during the downward movement). .

In addition, since the correct tissue structure determines the fabric, malfunction of the feeder determines the quality of the fabric. The jack lever male portion 49 and the malfunction detection sensor 48 of FIG. 1 are connected to the jack lever male portion 49 during operation. In the interval of the malfunction sensor 48, the control unit, which is stored as a fabric tissue, detects a malfunction and immediately stops the movement. The malfunction detection sensor group detects the operation of the jacklever link moisture group as the fabric of the computer.

Therefore, in the prior art, the doser is mechanically driven in a narrow space only in a high speed, and difficult to achieve high speed (movement selective amplification only on one side). In addition to widening the natural space, making the parts larger and stronger, the solenoid movement is directed from the computer according to the fabric structure, so that the speed and precision of the weaving can increase the weaving performance and quality.
