Description

Hosiery knitting machine capable of making out pile pattern bidirectionally.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sock knitting machine, and more particularly, to a sock knitting machine capable of knitting an outfit pattern in both directions capable of quickly and easily knitting an outfit pattern in both directions using one actuator.

Generally, a sock knitting machine automatically knits a sock, and the sock automatically knitted by such a sock knitting machine is largely composed of a foot, a sole, an ankle, a forefoot and a heel.

Recently, in order to improve the quality of socks, pile socks with the functions of thermal insulation and cushion were proposed. In such a file sock, the forefoot and the heel are individually organized into pile or plain weave, respectively.

On the other hand, when the golf, mountain climbing, or athletic work is performed, the pressure is applied mainly to the big toe portion. Thus, in the case of the sports sock, the thumb toe portion of the forefill is a file It is preferable to knit into the plain plain weave having a thinner thickness than the pile, because it is preferable to knit the weft and the other parts except for the big toe area, the cushion will cause a feeling of poor fit. Therefore, in recent years, there is a demand for a functional sock that can relieve the partial pressure of the forefoot and the heel ergonomically.

Conventionally, however, since the forearm and the heel of the sock are formed as a pile or plain plain weave using an actuator that is automatically controlled according to the input program of the computer, the cushion of the heel and the heel of the sock is required There is a structural problem in that the pile can not be partially formed only at the portion where the legs and the heel are partially sewn. As a result, conventionally, the functional socks which can relieve the partial pressure of the forefoot and the heel are ergonomically knitted There was no problem.

To solve such a problem, Japanese Patent Application Laid-Open No. 2008-0034060 proposes a first actuator and a second actuator, which are automatically controlled in accordance with an input program of a computer, on both sides of a central cam, So that the second actuator can advance the sinker selected during the reverse rotation more than during the plain knitting so as to partially pile the heel and the heel of the sock, So that the pile of the sock can be partially knitted only in the area where the cushion is required when the heel and the heel are knitted, and at the same time, the area requiring airflow can be easily selected and knitted into the plain plain weave.

However, in the conventional sock knitting machine having the above-described configuration, two actuators are installed on both sides of the center cam for forming an outfit pattern on the sock, and are automatically controlled in accordance with the program of the computer, and the sinker is advanced to knit the pile Structure of the sock knitting machine due to the installation of the two actuators is complicated and the manufacturing cost is increased.

6, the main sinker 120 is disposed between the knitting needles (not shown) and contacts the fingers 172 when the actuators 170 of the actuators 170 are operated, The sinker 130 pushes forward to form an outfit pattern on the forefoot or heel of the sock.

The main sinker 120 according to the present invention has a structure in which a separate protrusion structure for contacting the fingers 172 of the actuator 170 is not provided at the rear end, unlike the conventional sinker structure.

In the sock knitting machine 100 of the present invention, the main sinker 120 and the auxiliary sinker 130 are connected to each other, So as to form an outfile pattern while selectively moving forward.

The auxiliary sinker 130 is disposed on the rear side of the main sinker 120. When the actuator 170 is driven, the auxiliary sinker 130 is brought into contact with the fingers 172 to advance, pushing the main sinker 120 located on the front side, So that out-file patterns can be formed through the main sinker 120.

At this time, a protrusion 132 to be brought into contact with the finger 172 of the actuator 170 when the outfit pattern is knitted is formed at the rear end of the auxiliary sinker 130, and the protrusion 132, which can be moved on the outer surface of the auxiliary cam 160, A guide protrusion 134 protruding upward is formed.

As shown in FIG. 3 or FIG. 4, the auxiliary sinkers 130 of this type are arranged in a group of about 4 (stages) to 6 (stages) as shown in FIG. 3 or 4, The protrusions 132 of the sinker 130 are formed at positions that do not overlap each other.

The auxiliary sinker 130 is inserted into the slot 112 of the sinker bed 110 to be movable back and forth in a state where the auxiliary sinker 130 is inserted.

6, when the finger 172 of the actuator 170 is operated upward, the protrusion 132 of the auxiliary sinker 130, which rotates along the circumferential direction of the sinker bed 110, 172 of the auxiliary sinker 130 is in contact with the rear surface of the main sinker 120 while the groove 136 of the auxiliary sinker 130 is in contact with the first guide surface 174 of the main sinker 120 while moving forward along the first guide surface 174. [ , The main sinker 120 is advanced to the front side position where the pile can be directly sewn, thereby making it possible to organize an outfit pattern through the main sinker 120.

The auxiliary sinker 130 is formed with a groove 136 such that a portion of the groove 136 in the shape of a letter 'B' is disposed on the rear side of the main sinker 120 when the auxiliary sinker 130 is advanced. The forward movement of the main sinker 120 is stably performed.

The sinker guide 140 guides the movement of the main sinker 120 in the circumferential direction at the time of knitting of the sock and guides the movement of the main sinker 120 in the back and forth direction.

The sinker guide 140 is installed on the bottom surface of the sinker cover 150 and the main sinker 120 including the auxiliary sinker 130 is moved forward The actuator 170 is provided.

The sinker cover 150 is provided to cover the upper portion of the sinker bed 110 and protects the main sinker 120 and the auxiliary sinker 130 and protects the auxiliary cam 160 including the sinker guide 140 Respectively.

At this time, a support bracket (not shown) for supporting the actuator 170 is installed on one side of the sinker cover 150.

8 and 9, an annular ring cam 180 for guiding the movement of the auxiliary sinker 130 in the circumferential direction is provided on the bottom surface of the sinker cover 150. As shown in FIG.

The ring cam 180 is configured such that when the auxiliary sinker 130 moves along the circumferential direction, the guide protrusion 134 at the upper end of the auxiliary sinker 130 is constrained to the inside of the ring cam 180, (130) is prevented from being released.

The auxiliary cam 160 is disposed on the outer side of the sinker guide 140 to guide the movement of the main sinker 120 and the auxiliary sinker 130 together with the sinker guide 140, The forward movement of the auxiliary sinker 130 is guided when the outfit pattern is formed by the backward rotation.

The auxiliary cam 160 includes a pair of first and second auxiliary cams 161 and 162 arranged symmetrically with respect to the actuator 170 on the left and right.

Here, the first sub-cams 161 have the same shape and are symmetrically arranged on the left and right sides of the actuator 170 on the outer side of the sinker guide 140.

A first guide surface 161a is formed at one side of the first auxiliary cam 161 and has a curved shape corresponding to the shape of a part of the outer surface of the sinker guide 140 and guides the movement of the main sinker 120.

The other side of the first auxiliary cam 161 is spaced apart from the second guide surface 162b of the second auxiliary cam 162 by a predetermined distance and is supported with the second guide surface 162b of the second auxiliary cam 162 A second guide surface 161b for guiding the movement of the sinker 130 is formed.

7, when the main sinker 120 rotates along the circumferential direction while being engaged with the sinker guide 140, the protruding end 124 formed at the upper end of the main sinker 120 contacts the sinker guide 140, And moves along the path between the outer surface of the guide 140 and the first guide surface 161a of the first sub cam 161. [

A pair of second auxiliary cams 162 for guiding the movement of the auxiliary sinkers 130 are provided at positions adjacent to the first auxiliary cams 161.

The second sub-cams 162 have the same shape as the first sub-cams 161 and are disposed symmetrically on the left and right with respect to the actuators 170.

When the finger 172 of the actuator 170 is in operation, the auxiliary sinker 130, which is in contact with the finger 172 and is advanced a predetermined distance, A first guide surface 162a inclined in a curved shape that allows the guide protrusion 134 of the auxiliary sinker 130 to move in contact with the outer surface of the auxiliary sinker 130 can be moved forward.

In order to separate the auxiliary sinker 130 moved forward along the first guide surface 162a from the main sinker 120 and to escape to the rear side on the other side of the second auxiliary cam 162, A second guide surface 162b for forming a passage through which the guide protrusion 134 of the auxiliary sinker 130 is guided together with the second guide surface 161b of the auxiliary cam 161 is formed.

A third guide surface 162c is formed on the other side of the second auxiliary cam 162 to provide a path of movement of the auxiliary sinker 130 that is not in contact with the finger 172 of the actuator 170 when the plain weave is formed. do.

7 or 9, the auxiliary sinker 130, which is first advanced by a predetermined distance forward when brought into contact with the fingers 172 of the actuator 170, The main sinker 120 is moved forward by the second guide surface 162a of the second auxiliary cam 162 to advance to the pile formation position and then the guide protrusion 134 is moved to the second auxiliary cam 162 to move rearward through a path between the second guide surface 161b of the first sub cam 161 and the second guide surface 162b of the second sub cam 162, And then joins the auxiliary sinker 130 moving along the third guide surface 162c of the second auxiliary cam 162 and the inner surface of the ring cam 180 to be separated from the auxiliary sinker 130 in the circumferential direction .

The guide protrusion 134 of the auxiliary sinker 130 when the pile or plain weave is formed has a path between the ring cam 180 and the second sub cam 162 and a path between the first sub cam 161 and the second sub cam 162, and then moves along the second auxiliary cam 162 while being joined together.

On the other hand, when the auxiliary sinker 130 is moved forward by the first sinker 130 in contact with the finger 172 of the actuator 170 at the time of manual punching, the guide protrusion 134 of the auxiliary sinker 130 is moved to the second sub cam 162 The auxiliary sinker 130 rides on the first guide surface 162a and reaches the second guide surface 162a while surely riding the first guide surface 162a through the boundary portion between the first guide surface 162a and the third guide surface 162c, The main sinker 120 can be advanced forward by moving forward.

The finger 172 of the actuator 170 has a short stroke length to push the auxiliary sinker 130 forward because the length of the first and second guide surfaces 174 and 176 is short, The main sinker 120 can not be pushed all the way to the front side position where the punching can be performed.

Therefore, a structure for secondarily pushing the auxiliary sinker 130 advanced by a certain distance by the contact of the fingers 172 to a position where pile formation is possible is required. This is because the first auxiliary cam 162 May be implemented through the guide surface 162a.

That is, the auxiliary sinker 130, which is brought into contact with the fingers 172 and is first advanced forward by a predetermined distance, moves forward in the course of the guide protrusion 134 moving along the first guide surface 162a of the second sub cam 162 So that the main sinker 120 can be pushed up to a position where the punching can be performed.

At this time, the auxiliary sinker 130 is not completely seated on the first guide surface 162a of the second sub cam 162 due to the stroke limit along the length of the first guide surface (or the second guide surface) of the finger 172 If the first auxiliary cam 162 is caught by the edge portion of the second auxiliary cam 162, the smooth operation of the auxiliary sinker 130 may be hindered.

10 and 11, a third guide surface 162c having a stepped shape is formed on an outer surface adjacent to the first guide surface 162a of the second auxiliary cam 162, The third guide surface 162c and the second guide surface 162c are formed such that the step width of the third guide surface 162c decreases from the position adjacent to the first guide surface 162a to the position adjacent to the second guide surface 162b, A surface connecting the outer edge of the cam 162 is formed to have an inclined surface 138 and a guide protrusion 134 of the upper part of the auxiliary sinker 130 is formed in the same direction as the inclined surface 138 of the second auxiliary cam 162 Thereby forming an inclined surface 138 of an inclined shape.

10, the portion of the guide protrusion 134 is in contact with the second auxiliary cam 162, as shown in FIG. 10, so that the auxiliary sinker 130, which is in contact with the finger 172 of the actuator 170 and is first advanced forward, The main sinker 120 is moved forward along the bending of the first guide surface 162a while being seated on the first guide surface 162a of the main sinker 120 and pushes the main sinker 120 forward, The auxiliary sinker 130 which is not in contact with the fingers 172 and allows the knitting of the knitting yarn is knitted in such a manner that the guide protrusion 134 is located on the rear side of the second auxiliary cam 162 The auxiliary sinker 162 moves along the third guide surface 162c in contact with the stepped third guide surface 162c and the inclined surface 163 to be separated from the first auxiliary cam 161 and the second auxiliary cam 162, 130).

By forming the inclined surface 163 including the third guide surface 162c in the stepped shape at the portion of the second auxiliary cam 162 adjacent to the first guide surface 162a, The sinker 130 is smoothly moved forward by riding on the first guide surface 162a of the second sub cam 162 while the auxiliary sinker 130 not tilted is guided by the stepped third guide surface 162c and the inclined surface 163 It is possible to smoothly move the second auxiliary cam 162 to the rear side of the second auxiliary cam 162 so as to prevent the operational error that the guide protrusion 134 of the auxiliary sinker 130 is caught by the edge portion of the second auxiliary cam 162 Thus, the file directing operation can be performed smoothly.

Meanwhile, in the present invention, the sinker bed 110 rotates in both forward and reverse directions and forms an outfit pattern on the sock is configured to be operable through one actuator 170.

In other words, conventionally, two actuators are provided on the outer side of the sinker guide to advance the sinker through the one side actuating actuator to form the pile on the entire sock, and forward the sinker through the other actuator In the present invention, however, one actuator 170 is used to perform such operations as described above.

To this end, a single actuator 170, which is automatically controlled by a computer program, is installed outside the ring cam 180.

The actuator 170 is provided with a plurality of fingers 172 for forwarding the main sinker 120 by pushing the auxiliary sinker 130 forward or backward when the pile is formed.

The fingers 172 selectively move the protrusions 132 of the auxiliary sinker 130 rotating in the forward and reverse directions to move the auxiliary sinker 130 forward. The main sinker 120 advances by advancing to enable file directing.

At this time, the finger 172 is in contact with the protruding portion 132 of the rear end of the auxiliary sinker 130 when the sinker bed 110 is rotated forward and backward, and the portion of the guide protrusion 134 of the auxiliary sinker 130, The first and second guide surfaces 174 and 176 are formed so as to push toward the first guide surface 162a.

In this case, the first guide surface 174 and the second guide surface 176 can advance the auxiliary sinker 130 forward by the contact of the fingers 172 during forward / reverse rotation of the sinker bed 110 So as to have mutually symmetrical inclined surfaces.

When the actuator 170 is automatically controlled by a computer program and the actuator 170 is turned off, the finger 172 is lowered so that the projecting portion 132 of the auxiliary sinker 130 is not in contact with the auxiliary sinker 130, The main sinker 120 is moved along the inner surface of the ring cam 180 without being advanced to the front side so that the main sinker 120 is moved along the sinker guide 140 in a state where the main sinker 120 is not advanced, do.

On the other hand, when the actuator 170 is turned on, the finger 172 rises and comes into contact with the protruding portion 132 of the auxiliary sinker 130 of the auxiliary sinker 130, so that the auxiliary sinker 130 moves forward The guide protrusion 134 moves along the first guide surface 162a of the second sub cam 162 to advance the auxiliary sinker 130 forward while the distance is advanced. In the process of advancing the auxiliary sinker 130, The main sinker 120 is pushed toward the front side to advance the main sinker 120 more than when the main sinker 120 is formed into a plain weave, thereby enabling pile formation.

The overall operation of the sock knitting machine 100 according to the present invention will now be described in detail with reference to FIGS. 6 to 11. FIG.

First, when the outfitter pattern is formed on the sock while the sinker bed 110 of the sock knitting machine 100 is rotated in the forward / reverse direction, when the turn display actuator 170 of the sinker bed 110 is turned off, the actuator The finger 172 of the auxiliary sinker 170 and the protruding portion 132 of the auxiliary sinker 130 are not brought into contact with each other and the main sinker 120 including the auxiliary sinker 130 is not moved forward.

When the actuator 170 is turned off during the reverse rotation of the sinker bed 110, the finger 172 and the protrusion 132 are not brought into contact with each other and the forward movement of the main sinker 120 including the auxiliary sinker 130 It is organized into plain weave as the movement is not made.

On the other hand, when the actuator 172 is turned on when the sinker bed 110 is rotated forward or backward to knit the outfit pattern on the sock while rotating the sinker bed 110 in the forward / The guide projections 134 of the auxiliary sinkers 130 ride on the first guide surfaces 162a of the second sub cams 162 and the auxiliary cams 130 The auxiliary sinker 130 is advanced secondarily so that the front main sinker 120 is pushed and advanced forward than when the plain weave is knitted.

When the sinker bed 110 is rotated in the forward and reverse directions when the outfit pattern is formed on the sock, the operation of the actuator 170 is turned on only during the period in which the pile formation is required, When the auxiliary sinker 130 is advanced through the two guide surfaces 174 and 176, the guide protrusion 134 of the auxiliary sinker 130 moves forward while moving along the first guide surface 162a of the second auxiliary cam 162 The main sinker 120 can be advanced further forward than when the main sinker 120 is formed through the auxiliary sinker 130, so that the forefoot or heel portion of the sock can be formed as a pile having a cushion.

The auxiliary sinker 130 is first moved forward while being selectively in contact with the first and second guide surfaces 174 and 176 of the finger 172 when the outfit pattern is formed on the sock, 1 guide surface 162a to move forward and push the main sinker 120 forward so that direct sewing of the pile can be realized. Therefore, the out-file pattern can be partially It can be easily and automatically formed.

In addition, since the forefoot and heel of the sock can be individually knitted into a plain weave or a pile, and in particular, by using one actuator 170, it is possible to knit a pile partially in only a portion where cushion is required when the sock is knitted The apparatus structure of the sock knitting machine 100 can be implemented simply and compactly, and the number of actuators to be used can be reduced, thereby reducing manufacturing costs.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limited to the embodiments set forth herein. Will be possible.
