GUIDE PIN OF DIAL LOOP PIN}

The present invention relates to a dial loop pin and a guide pin for a double-sided machine, and more particularly, when the pile yarn is pulled in the direction of the dial through the latching jaw formed on the upper end of the loop pin to be in close contact with the hook of the latch needle. As well as preventing the latch needle from missing the pile yarn, the inclined surface formed at the top of the guide pin allows the pile yarn to be peeled off and the latch needle is knitted with the pile yarn caught on the latching jaw, thereby increasing the quality and productivity of the loop pile. And a loop loop pin and a guide pin for a double-sided machine.

In general, loop piles are organized using a double-sided machine. The double-sided machine as described above has a loop pin 30 inserted into the needle bed groove of the dial and advanced to receive the pile yarn 40 as shown in FIGS. 1 and 3, and the loop pin 30 is pile yarn. When the 40 is supplied, it is made up of the latch needle 10 of the cylinder for knitting the loop pile while receiving the pile yarn 40 in a raised state.

Looking at the structure of the loop pin 30 used in the conventional double-sided machine as described above, the head 32 portion of the loop pin 30 is simply formed in a date without a locking structure, the operation cam (not shown) The butter 31 is connected to the loop pin 30 to move forward and backward.

This structure has a structure in which the head 32 side of the loop pin 30 supplied with the pile yarn 40 is formed in a straight line so that the pile yarn 40 cannot be dragged and entered into the dial side. Therefore, when the pile yarn 40 is loosened due to peripheral factors when the loop pile is knitted, the phenomenon that the pile yarn 40 deviates from the inside of the hook 20 of the latch needle 10 occurs. This phenomenon is not only the productivity is greatly reduced because the double-sided machine is frequently shut down and must always operate at a low speed, the quality of the product is greatly reduced by re-knitting the pile yarn 40 during the vertical movement of the latch needle (10) There was a problem such as being ..

An object of the present invention has been made in view of the above problems, the pile yarn is pulled in the direction of the dial through the locking jaw formed on the upper end of the loop pin to be in close contact with the hook of the latch needle, the latch needle is pile yarn during knitting It is to provide a dial loop pin and a guide pin for a double-sided machine so that the miss is prevented.

Another object of the present invention is to release the pile yarn hanging on the latching jaw through the inclined surface formed on the upper surface of the guide pin to latch the loop pile pile, thereby increasing the quality and productivity of the loop pile pile dial To provide loop pins and guide pins.

As a means for achieving the above object, the present invention, while inserting the loop pin and two guide pins in one couch, the upper end of the front end of the loop pin to form a locking projection protruding to the outside supplied pile yarn Dragging in the dial direction to be in close contact with the hook of the latch needle; After forming the inclined surface on the upper end of the guide pin, the technical characteristics of the technical configuration of the latch needle to form a loop pile while the pile yarn hanging on the locking jaw through the inclined surface is peeled off.

As described above, in the present invention, a locking jaw is formed at an upper end of the loop pin. Therefore, the pile yarn is attracted to the inside of the hook of the latch needle because the pile yarn is pulled in the dial direction by the catching jaw when knitting the loop pile in the duplex machine. This not only prevents the latch needles from missing pile yarns when organizing a roopu pile, but also keeps the machine running without interruption.

In addition, a guide pin having an inclined surface is separately inserted into the needle groove of the dial. Therefore, since the pile yarn caught on the locking jaw is peeled off through the inclined surface formed on the top of the guide pin, the latch needle can smoothly organize the loop pile, and the quality and productivity of the loop pile can be further increased. will be.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The double-sided machine of the present invention is also inserted into the needle groove 500 of the dial and moves forward to receive the pile yarn 400, and the loop pin 100 rises when the pile yarn 400 is supplied. It is made of a latch needle 300 of the cylinder to form a loop pile while receiving the pile yarn 400 is supplied in the state and is basically operated as in the prior art. Therefore, hereinafter, a method in which the loop pile is knitted by the loop pin 100 and the latch needle 300 in the duplex machine will be omitted.

However, the present invention is to allow the loop pile to be more effectively knitted on the double-sided machine, the loop pin 100 and the guide pin 200 in the needle groove 500 formed on the dial side as shown in Figs. The dog has a basic configuration into which it is inserted.

The upper end of the front of the loop pin 100 is formed by a hooking jaw 110 that protrudes to the outside and pulls the supplied pile yarn 400 in the dial direction, and piles the pile yarn 400 inside the hook 310 of the latch needle 300. ) To be in close contact.

After the inclined surface 210 is formed on the upper surface of the guide pin 200, the latch needle 300 knits the loop pile while the pile yarn 400 caught on the locking jaw 110 is peeled off through the inclined surface 210. It is configured to be.

Here, the butters (120) and (220) formed at the top rear of the guide pin (200) and the loop pin (100) are formed at different positions, and the butter (120) (220) has a respective operation cam ( Not shown) is connected to the guide pin 200 and the loop pin 100 is configured to operate differently.

In order to use the present invention configured as described above, after preparing the guide pin 200 having the loop pin 100 and the inclined surface 210 having the locking step 110 is formed, respectively, and then the prepared guide pin 200 and the loop pin 100 ) Is placed in one couch groove (500).

When operating the double-sided machine in the above state, the guide pin (200) and the loop pin (100) to advance at the same time in the needle groove (500) in order to receive the pile yarn 400 on the upper end of the loop pin (100) The formed locking step 110 receives the pile yarn 400 in a state in which the pile yarn 400 is locked. At this time, when the latch needle 300 supplied with the pile yarn 400 descends, the loop pin 100 and the guide pin 200 simultaneously retreat toward the dial direction. Since the 400 is pulled in the dial direction, the pile yarn 400 is in close contact with the hook of the latch needle 300. When the close contact is completed, the guide pin 200 stops and only the loop pin 100 continues to reverse in the dial direction.

If the loop pin 100 continues to retreat while the file yarn 400 is caught on the hooking jaw 110 as described above, the file yarn 400 caught on the hooking jaw 110 is in the stopped state. While going up along the inclined surface 210 of the loop pin 100 is separated from the locking jaw (110).
