Apparatus for driving thread guider of knitting machine

The present invention relates to, and more particularly to.

Sado is a part for guiding the supply path of the yarn, and is used in knitting machines for weaving fabrics such as sock knitting machines. In general, socks are classified into plain fabric socks that are knitted in a single layer, such as men's socks, and three-dimensional pile fabric socks that are vertically sanded on a single layer, such as sports socks. In this case, in order to weave one sock, a plurality of threads are generally used, and a sock knitting machine is provided with a plurality of parts, namely, apostles.

Hereinafter, with reference to the accompanying drawings will be described in detail a conventional driving device for knitting machine.

1 is a side view of a conventional knitting machine driving device for knitting machines, and FIG. 2 is a partial perspective view of a knitting machine showing a conventional knitting machine driving device mounting shape for knitting machines.

The yarn driving device for knitting machines is to adjust the feeding path of the yarn by rotating the yarn knitting machine for guiding the feeding path of the yarn. As shown in FIG. 1, one side of the yarn 10 for the knitting machine (the right side in FIG. 1). ) The pressing pin 20 for pushing down, the downward air cylinder 30 for moving the pressing pin 20 up and down, and the other side (the right side in FIG. 1) of the yarn 10 for the knitting machine upward. It comprises a lifting spring 40.

The pressing pin 20 is a first pressing pin 21 having a long stroke so as to lower one side of the knitting machine yarn 10, and short so that one side of the knitting machine yarn 10 can be lowered only until the interruption. It may be configured to include a second pressing pin 22 having a stroke. In addition, the downward air cylinder 30 includes a first downward air cylinder 31 and a second downward air cylinder 32 for moving the first pressing pin 21 and the second pressing pin 22, respectively. It is composed.

In this case, the first pressing pin 21 and the first downward air cylinder 310 are respectively installed on all knitting yarns 10, the second pressing pin 22 and the second downward air cylinder 32, respectively Is additionally installed only in the yarn 10 for knitting machines that one side only needs to go down to the stop.

The knitting machine yarn 10 and the downward air cylinder 30 is coupled to one fixture 50 so that the rotation angle of the knitting machine yarn 100 according to the operation distance of the pressing pin 20 can be precisely maintained. Is preferred. At this time, the knitting machine yarn 10 is coupled to the fixture 50 by the hinge bracket 51 so that the suspension can be rotated.

1 is a state in which one end of the knitting machine yarn 10 is pulled up as much as possible, that is, rotated in the counterclockwise direction as much as possible about the hinge bracket 51. In such a state, when the downward air cylinder 30 pushes down the pressing pin 20 downward, the knitting machine yarn 10 is pushed downward in one end in a clockwise direction about the hinge bracket 51. Is rotated.

In addition, when the pressing pin 20 is raised to the upper side in the state in which the pressing pin 20 is lowered so that one end of the knitting machine 10 is lowered downward, the knitting machine 10 is a spring 40. By the elastic force of the) as shown in FIG.

As described above, in the conventional four-screw driving device for knitting machines, the compressed air supply and shut-off operation to the downward air cylinder 30 is driven by separate compressed air supply means. Typically, the compressed air supply means is compressed as described above. Since there is a limit to the quick and accurate switching of the air supply and shut-off operation, there is a disadvantage in that the rotation of the yarn 10 for knitting machines can not be implemented quickly.

In addition, the compressed air supply means is typically located at a point spaced apart from the downward air cylinder 30 and connected by a tube having a considerable length, thus supplying and blocking compressed air to the downward air cylinder 30. When the control point is far away from the downward air cylinder 30, the compressed air supply and cut off responsiveness is reduced, it is difficult to immediately rotate the yarn 10 for knitting machines.

In addition, the knitting yarn 10 for the knitting machine, when one side is lowered by the lowering of the pressing pin 20 is lowered to the lower side than the pressing pin 20 by the inertia, and the elasticity of the spring 40 One side is raised again to be in contact with the pressing pin 20. At this time, the knitting yarn 10 is lowered further down than the pressing pin 20 and comes back up in contact with the pressing pin 20, not only the operation noise is increased due to the large blow sound, but also There is a problem that there is a fear that the knitting yarn for knitting machine 10 is damaged or broken.

In addition, the conventional knitting machine driving device for the knitting machine, the downward air cylinder 30 for rotating the knitting machine yarn 10 is mounted so as to stand vertically above the knitting machine yarn 10, the height of the entire apparatus Is high, and thus a larger mounting space is required.

The present invention has been proposed in order to solve the above problems, it is possible to quickly implement the turning and turning direction of the yarn for knitting machines, can reduce the risk of noise or damage generated when the yarn for knitting machine rotation, and miniaturization It is an object of the present invention to provide a yarn driving device for a knitting machine configured to be possible.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of a yarn driving device for a knitting machine according to the present invention.

3 is a side cross-sectional view of a yarn driving device for a knitting machine according to the present invention, Figures 4 and 5 are an exploded perspective view and a perspective view of a drive block included in the yarn driving device for a knitting machine according to the present invention, Figure 6 is a present invention Is a perspective view of a support block included in a yarn driving device for a knitting machine.

3 to 6 as a driving device for knitting machine knitting machine according to the present invention is a driving device for rotating the knitting machine yarn 200 is mounted on the base block 100, the compressed air passage 310 therein Drive block 300 is formed, the compressed air opening and closing valve 500 for blocking and releasing the compressed air flowing into the compressed air flow path 310 and the drive block 300 to be slidable in the longitudinal direction Compression pins, one end of which is coupled by the compressed air applied to the compressed air flow path 310 to protrude to the outside of the driving block 300 to push the pressing portion 210 formed at the rear end of the yarn 200 for the knitting machine. 400).

As described above, according to the present invention, the yarn driving device for a knitting machine includes a compressed air passage 310 for guiding the compressed air to the pressure pin 400, and is not made of a separate tube or a hose as in the prior art, and the inside of the driving block 300 is provided. It is formed in, even if the external impact is applied or operated for a long time there is no fear of damage and deformation of the compressed air flow path 310, there is no fear of bending or folding the compressed air flow path 310 operation of the pressure pin 400 The reliability is improved and the appearance is neat.

At this time, the compressed air on-off valve 500 is coupled to the surface (in the right side of the drive block 300 in Figure 3) the inlet of the compressed air flow path 310 of the outer surface of the drive block 300, the compressed air Compressed air supply means (not shown) to supply always maintains the state to supply the compressed air to the compressed air on-off valve (500).

In the related art, since the compressed air supply means itself determines whether to supply compressed air, the operation of the yarns 200 and 10 for the knitting machine was performed only after a predetermined time elapsed from the time point at which the compressed air was supplied. The yarn driving device for the knitting machine has the advantage that the operation speed of the knitting machine 200 for the knitting machine 200 is very fast since the compressed air on / off valve 500 for determining whether to supply the compressed air is in a very close position to the pressure pin 400. There is this.

That is, the conventional knitting machine driving device for knitting machines does not operate the knitting machine yarns 200 and 10 immediately after it is determined whether to supply compressed air, but it takes the compressed air to move from the compressed air supply means to the downward air cylinder 30. After the time has passed, the knitting machine yarns 200 and 10 are operated, and the knitting machine driving machine according to the present invention has a time taken for moving the compressed air from the compressed air open / close valve 500 to the pressure pin 400. Since the pastoral drive device is operated, since the distance from the compressed air open / close valve 500 to the guide pin 600 is very short compared to the distance from the compressed air supply means to the downward air cylinder 30, according to the present invention. The operation response speed of the yarn driving device for the knitting machine becomes very fast.

In addition, the compressed air open / close valve 500 may be applied as a solenoid valve for opening and closing the flow path by reciprocating by an electrical signal so that whether or not the compressed air is delivered to the compressed air flow path 310 is controlled by an electrical signal.

As such, when the compressed air open / close valve 500 is applied to the solenoid valve, it is possible to quickly switch whether or not to deliver the compressed air to the pressure pin 400 to further increase the operation reaction speed of the yarn 200 for knitting machines. And, there is an advantage that the control of the delivery of compressed air to the pressing pin 400 can be made more simply and stably.

Of course, the compressed air open / close valve 500 may be replaced with any type of valve as long as it can open and close the compressed air flow path 310.

At this time, the pressing pin 400 is configured to include a first pressing pin 410 and a second pressing pin 420 different in length pushing the knitting machine 200 for the knitting machine, the knitting machine 200 for It is possible to rotate at different angles. As described above, an operation in which the rotation angle of the knitting machine 200 for knitting machine 200 differs by the first pressing pin 410 and the second pressing pin 420 will be described with reference to the accompanying drawings.

In addition, if the distance from which the pressing pin 400 protrudes from the driving block 300 is too far, the pressing pin 400 may be bent as the process of hitting the yarn 200 for the knitting machine is repeated. , The protruding direction of the pressing pin 400 is difficult to maintain a constant. Therefore, in the driving block 300, a guide pin 600, which is formed with a guide hole 610 through which one end of the pressure pin 400 passes, may be coupled around the pressure pin 400. At this time, the guide pin 600 is fixedly coupled to the drive block 300 by a fixing screw 620 is fastened to both sides of the drive block 300.

In the present embodiment, the guide pin 600 is provided only on the first pressing pin 410, but the guide pin 600 may also be provided on the second pressing pin 420.

In addition, the knitting machine driving device according to the present invention, the support block 710 is fixedly coupled to the base block 100, and the support pin 720 is coupled to the support block 710 in a sliding structure in the longitudinal direction. And, it may be configured to further include a spring 730 for applying an elastic force to the support pin 720 in the direction toward the knitting machine 200.

The support pin 720 is a part of the knitting machine yarn 200 (the support portion 220 formed in the lower side of the knitting machine yarn 200 in Figure 3) when the knitting machine yarn 200 is rotated. It is contacted, and is mounted to the support block 710 in a structure that is pushed by the knitting yarn 200 for the longitudinal movement.

Therefore, the yarn 200 for the knitting machine is in close contact with the support pin 720 in the direction in which the spring 730 is compressed when pushed by the pressing pin 400, the pressing pin 400 is protruded to the end no longer If it does not protrude, it is not rotated further by inertia and the rotation is stopped as soon as the protrusion of the pressing pin 400 is finished.

In this case, the support block 710 is preferably made of a material having elasticity so as to absorb vibration generated when the support portion 220 of the knitting machine 200 for the knitting device hit the support pin 720. .

In addition, when the knitting machine 200 is configured such that the rotation angle is determined only by the protruding distance of the pressing pin 400, there is a problem that the maximum rotation angle of the knitting machine 200 can not be finely adjusted. .

In order to solve this problem, the knitting machine driving device according to the present invention, the support pin 720 when the support pin 720 is pushed by the knitting machine 200 so that the support so that one end interferes with the support pin (720) A bolt 740 coupled to the block 710 to define the distance of the support pin 720, and a position where the bolt 740 is coupled to the support block 710 by screwing the bolt 740 Nut 750 to adjust the may be further provided.

Therefore, the user can adjust the maximum rotation angle of the knitting machine 200 for knitting machine 200 by rotating the nut 750 to adjust the position of the bolt 740 in the direction closer to or away from the support pin 720. That is, when the position of the bolt 740 is closer to the support pin 720, the distance that the support pin 720 is pushed back by the knitting machine 200 for the knitting machine is shortened, so that the rotation of the knitting machine 200 for the knitting machine accordingly The angle becomes smaller. On the contrary, when the position of the bolt 740 is far from the support pin 720, the distance that the support pin 720 is pushed back by the knitting machine 200 for the knitting machine becomes long, so that the rotation of the knitting machine 200 for the knitting machine accordingly. The angle becomes larger.

7 and 8 are side cross-sectional views showing an example of the operation of the yarn drive device for a knitting machine according to the present invention.

When the first pressing pin 410 protrudes in the state shown in FIG. 3, the yarn 200 for the knitting machine rotates counterclockwise around the suspension coupled with the hinge bracket 110 as shown in FIG. 7. Done.

At this time, the support pin 720 mounted in the support block 710 is pushed back by the support portion 220 of the yarn 200 for knitting machine, the spring 730 mounted in the support block 710 is compressed and the The support pin 720 is elastically pressed toward the support part 220. Accordingly, the knitting machine 200 for the knitting machine does not generate additional rotation due to inertia when the protrusion of the first pressing pin 410 is stopped, and stops as soon as the protrusion of the first pressing pin 410 is stopped.

In addition, the second pressing pin 420 is configured to protrude more than the first pressing pin 410, when the second pressing pin 420 protrudes in the state shown in FIG. ) Is rotated more than when the first pressing pin 410 is protruded, as shown in FIG.

At this time, as shown in Figure 7, the support pin 720 mounted in the support block 710 is pushed back by the support portion 220 of the yarn 200 for knitting machines, mounted in the support block 710 The spring 730 is compressed to elastically press the support pin 720 toward the support 220. Accordingly, the knitting machine 200 for the knitting machine does not generate additional rotation due to inertia when the protrusion of the second pressing pin 420 is stopped, and stops as soon as the protrusion of the second pressing pin 420 is stopped.

In addition, when the second pressing pin 420 protrudes and the knitting machine 200 is rotated as much as possible, the support pin 720 pushed by the support part 220 is no longer interfering with the bolt 740. Since it is not pushed, the knitting machine 200 is no more rotated than the state shown in FIG.

Of course, when the user rotates the nut 750 to move the position of the bolt 740 in the direction away from the support 220, the knitting yarn 200 may be rotated more than the state shown in FIG. .

Fig. 9 is a perspective view showing a shape in which a yarn driving device for a knitting machine according to the present invention is mounted on a knitting machine.

In the yarn driving device for knitting machines according to the present invention, the driving block 300 for pressing and rotating the yarn knitting machine 200 is not located on the upper side of the knitting machine yarn 200, but behind the knitting machine yarn 200. Since the pressing pin 400 is positioned so as to protrude in the horizontal direction, the overall height of the knitting machine is lowered as shown in FIG. 9 when the knitting machine driving device according to the present invention is mounted on the knitting machine.

That is, the mounting space constraint of the knitting machine according to the present invention is reduced when mounting to the knitting machine, and the use of the knitting machine driving machine according to the present invention can lower the overall height of the knitting machine, so the installation space of the knitting machine Constraints also have the advantage of being reduced.
