Apparatus for changing yarn using electronic-converting valve and fluid pressure in knitting machine}

The air stripper of a jacqard circular knitting machine. More specifically, the switching of the feed port for supplying various threads to the needles assembled in the circular knitting machine depends on the signal input to the computer. (Simply referred to as "fluid") relates to a striper for operating the yarn guide by the movement of the piston rod to send to move

In general, the configuration of supplying the thread to the knitting needle of the circular knitting machine forms a plurality of needle grooves extending in the axial direction parallel to the cylinder outer periphery, and each needle groove accommodates the knitting needle which slides freely in the vertical direction. The cam holder is assembled with a cam that controls or operates the needle, so that the sinker that operates with the needle is controlled in contact with the sinker dial assembled in the horizontal direction, and there are a plurality of yarn guides inside the cylinder to guide the thread to the needle. Assemble the assembled striper.

In the conventional jacquard circular knitting machine, as shown in Figs. 1 and 2, the striper is provided with a pair of solenoids 5 with respect to the sudden death finger to determine the selection of the operating yarn guide 61, and a raised cam at one end of the shaft end of the solenoid shaft.

Known thread telephone device is the front cover (30) diaphragm (31) yarn guide (33) ?? holder plate (34) movable cutter (35) stop cutter (36) in the order of the yarn guide (33 '), replaceable After repeated assembly by the number of yarns, the thick plate and the top cover are assembled, and there are two guide bars inside the diaphragm to guide the movement in the front and rear movement of the yarn guide 33. It is.

The yarn guides 33 and 33 'have a yarn guide hole 330 formed at one end thereof, and a curved front guide hole 331 contacting the front guide bar 37 is formed at the center thereof, and a rear guide bar is formed at the rear thereof. A rear guide hole 333 is formed in contact with 38, and the other end is formed with the pelts 335 and 335 'integrally.

The front guide hole 331 is a planetary type to prevent the yarn guide 33 from hitting the needle in the process of supplying the thread to the needle and the yarn holder in the yarn holder while the yarn guide 33 moves forward and backward. It is designed to retreat the battery by drawing a curve of.

The rear guide hole 333 is to minimize the vertical movement of the back of the butt (335,335 ') in the forward and backward movement of the yarn guide (33, 33').

In addition, when the assembling pins of the rear pin-shaped elastic pin 350 protrudes to the movable cart 35 after the yarn holder plate 34, the yarn guide plate 34 passes through the front yarn holder plate 34 and is a butt 335. ) And the cutter backward action surface 334 protrudes to the area of the yarn guide in the forward movement of the yarn guide in contact with the one side of the butt 335 of the yarn guide (35) is moving forward and the backward of the yarn guide 33 Is in contact with the cutter reverse action surface 334 of the yarn guide (33).

It was made to be stuck at (330).

The movable cutter 35 forms a blade groove 55 at one end and two protruding elastic pins 350 at the tile part to move back and forth when the yarn guide 33 moves back and forth. The through grooves 352 and 353 are placed in contact with the front and rear guide bars 37 and 38 to guide the direction during the forward and backward motion.

The stop cutter 36 faced the blade effective groove 351 of the movable cutter 35 to form a blade to help the cutting of the thread.

The electromagnetic switching valve hydraulic pneumatic cylinder chamber switching device according to the present invention having the configuration as described above is a high-pressure and low-pressure fluid pressurized by the high pressure suction port 101 by the electronic switching device the piston head inside the hydraulic cylinder When the high pressure fluid enters the front part and the low pressure fluid enters the back part, all the pistons are reversed by the pressure of the high pressure fluid.

In this state, in order to move the yarn guide 33 to supply the needle to the needle by the electric signal determined by the control box, it flows upward to the predetermined electromagnetic switching valve flow path blocking membrane 23 of the upper flow port 21. When the high pressure fluid is introduced into the front hydraulic pneumatic cylinder of the piston head 114 to block the orifice 21, the piston rod 13 is advanced and when the seal is not supplied, the electromagnetic valve flow path blocking membrane 23 of the injection port 20 is prevented. The inlet 20 is blocked and the upper flow port 21 is opened so that the fluid introduced into the rear pneumatic cylinder of the piston head 114 is discharged through the outlet 121 to be discharged outwards. There is no pressurized fluid in the cylinder hole, which causes the piston rod to move forward by the low pressure fluid behind the piston head.

The low pressure fluid should have sufficient pressure to move the yarn guide. This action does not require the forward and backward movement of the piston rod at one time, but may require an intermediate stop, in which case more flow paths and switching valves can be connected.

In the thread switching device, the thread is initially bitten between the yarn holder and the moving cutter, and the door is held between the yarn holder and the moving cutter until the yarn guide advances and the knitting needle pulls the yarn of the yarn guide hole. At this point you can have intermediate stops, which may require more flow paths and switching valves. After this point, the moving cutter begins to move forward in contact with the butt and forward elastic pins of the yarn guide, thus ending the forward motion. After the knitting, when the knitting yarn is replaced, another yarn guide shifts as described above, and after the knitting needle pulls the yarn, the yarn guide starts to reverse and guides the yarn into the Carter part of the moving carter. Then, the moving cart meets the resilient elastic pin and the yarn guide backward contact surface and starts to move backwards.Then, it moves further and meets with the yan holder, and holds the thread between the moving cart and the yarn holder. Complete.

By repeating this operation, the yarn may be supplied or the supply may be stopped to change the color or the sense of knitting on the knit fabric to form various patterns.

By using a fluid, a plurality of yarn guides are knitted by repeating forward and backward, so that the yarn can be exchanged at any position, which can change a lot on the knitting, and can knit various patterns as well. Compared with this, the structure is simple, there are few failures, and the repair is easy, so the operation efficiency is increased, and thus high productivity can be obtained.
