The present invention relates to a control device, and more particularly to a control device for controlling the operation of the stripper of the circular knitting machine when automatically changing the pattern Yaani.

The circular knitting machine as shown in FIG. 1 is equipped with a stripper and controlled by a stripper control device to change the pigmented yarn to make the color panel fabric.

Such stripper controls are complex in structure. 2, each stripper is controlled by a respective control device, which has four reciprocating rods, each controlled by computer control via a respective solenoid, so that each stripping Each stripping feeder changes the field by triggering each pressure plate as it moves further. Since the stripper is controlled by each control device, several controls must be used for the circular knitting machine. Therefore, the stripper control device of the conventional circular knitting machine is complicated in structure and expensive to install.

The object of the present invention is to eliminate the above drawbacks. To this end, the present invention uses a single controller to control all strippers of the circular knitting machine. The controller is supported on a rotary table and the strippers are spaced around the rotary table on a fixed bed plate. The controller has a plurality of rocking plates each controlled by a computer controlled solenoid to drive the stripping fingers of the fixed stripper when moving each stripping feeder to change the patterning yarn. Since each solenoid does not operate when no yaw change action is required, the stripping finger is not triggered by each rocking plate during the rotary motion of the rotary table. The above configuration allows the stripper to be controlled by a single controller. Therefore, the manufacturing cost of the stripper control device is greatly reduced, and the installation procedure thereof is also simplified.

Hereinafter, the present invention will be described in detail with reference to the drawings.

In FIG. 3, the stripper control device of the circular knitting machine according to the present invention has a controller 2 fastened to the rotary table 4 of the circular knitting machine, and is wound around the rotary table 4 to the controller 2. It consists of a plurality of strippers 3 each controlled by a. The number of strippers 3 may vary depending on the model of the knitting machine. The knitting machine preferably has 48 strippers controlled by a single controller 2.

In FIG. 4, the stripper 3 has a series of vertical slots 321 facing the rotary table 4, and shaft holes 322 through the vertical slots 321, so that the bolts 324 It consists of a base plate 32 fastened in two side walls 311 of the head 31. Vertical slots 321 each receive an F-shaped striping finger 33. The F-shaped stripping picker 33 includes a shaft hole 331 which is slidably attached to the shaft hole 322 on the base plate 32 in the vertical slot 321 by the pin 323, and an upper flange 332. And stub rods 333 protruding toward the rotary table at different heights, respectively. The position of the stub rod 333 on each F-shaped stripping finger 33 is very different. Once assembled, the top flange 332 of the F-shaped stripping finger 33 of the base plate 32 is installed at the same height, while the stub rod 33 has its respective pressure plate 34 and stripping feeder 35. Is supported above.

5 and 6, the controller 2 is fastened to the inner surface of the casing 21 and covered with a plurality of solenoids 22 covered with the front cover 24, the rear cover 25 and the upper cover 26, It consists of a plurality of rocking plates 23 each controlled to rock by the solenoid 22. Front cover 24 has wire holes 241 through which a conductor is inserted to electrically connect solenoid 22 to an external computer system (not shown). Each solenoid 22 is inserted into the position groove 231 on the swinging plate 23 and has a reciprocating rod 22 controlled to alternately move the rear fourth swinging plate 23. Each rocking plate 23 is inserted into each channel 211 on two opposing side walls of the casing 21 at its rear side, so that the two end rods 232 fixed in position by the positioning plate 212. On its two opposite ends, each having a side flap 233 with a cut edge extending from the back cover 25 through each slot 251. The side blades 233 of each rocking plate 23 may be provided in contact with the stub rods 333 on the respective F-shaped stripping fingers 33 of the stripper 3, and the stripper stopped in FIG. Since the gap between the two stub rods 333 of the two adjacent F-shaped stripping fingers 33 of (3) may be moved horizontally, rotating the rotary table 4 further changes the field of view. In order to move the stripping feeder 35 through each pressure plate 34, the F-shaped stripping fingers 33 of each stripper 3 are respectively driven by the swing plate 23.

In Fig. 7, while the circular knitting machine is in operation, the solenoid 22 of the controller 2 is controlled by the computer system through a pre-built control program. When the solenoid 22 is on, each reciprocating rod 222 moves the side vanes 233 of each rocking plate 23 from the stub rod 333 of each F-shaped stripping finger 33. So that each stripping feeder 35 does not work. Conversely, for the yaw to be changed, each solenoid of the controller 2 is pushed so that the side blades 233 of each oscillating plate 23 push the stub rods 333 of the respective F-shaped stripping fingers 33. As it is off, each pressure plate 34 reciprocates each stripping feeder 35 each time it changes the field of view. Since the tail 352 of the stripping feeder 35 moves outwards, the selected eye 6 is guided to be knitted by each needle 5 reciprocating up and down or cut by the cutter 353. do. Therefore, by means of the rotary motion of the rotary table 4 to support the controller 2, the stripper 3 is driven by the controller 2 to continue the yaw changing operation.
