That is, in the free flow conveyor 4, the front row 4a moves in the direction toward the guide slit 3 of the front stitch sewing machine 2, and the rear part moves in the opposite direction.

As shown in FIG. 3, this unit 5 has a setting member into which the toe portion 14 of the sock 13 is inserted. The setting member is a toe portion 1 of the sock 13.
Although it can be implemented as having a proper shape on the condition that it can be inserted into the inside, it is implemented as a plate-shaped setting plate 6 in this embodiment. The setting plate 6 has a shape (rectangular shape in this embodiment) to be inserted into the tip side of the sock, and has a pair of left and right tensioning portions 7 for matching the corner portions 16 of the tip sewing course 15 of the toe portion 14. To have. The tension portion 7 slightly projects to the left and right sides of the setting plate 6. This taut portion 7 is a corner portion 16 when it has a tapered shape.
However, it is not appropriate to use a sharp tip because it is caught on the knitted fabric of the sock more than necessary.

The setting plate 6 is provided so as to be vertically rotatable with respect to a vertical rod 11a provided so as to be movable up and down with respect to a column 20 standing on the substrate 5a of the unit 5. . In this embodiment, an arm 11b extends forward from the vertical rod 11a, and the tip of the arm 11b has a hanging part 11c that hangs downward. The lower end of the hanging part 11c and the lower end of the setting plate 6 are , Hinge 6
It is connected rotatably up and down by a. The vertical rod 11a is provided with a raising cam 11, and the vertical rod 11a and the setting plate 6 are raised by the raising cam 11.

More specifically, as shown in FIG. 4, the cam floor 11x is provided near the front row 4a of the free flow conveyor.
Is provided so as to be movable up and down by the air cylinder 11y. When the unit 5 approaches the cam floor 11x by the free flow conveyor 4 and the ascending cam 11 comes above the cam floor 11x, the piston rod of the air cylinder 11y extends, the cam floor 11x ascends, and the ascending cam 11 is pushed up. It is a thing. As will be described in more detail later, this rise is made to pull out the setting plate 6 from the toe portion 14.

Next, the substrate 5a of the unit 5 is provided with a pair of chucks 8. The chuck 8 is provided at a position where the pair of tension portions 7 of the setting plate 6 are located when the setting plate 6 is tilted toward the front as shown by the arrow in FIG.
The corner portions 16 of the toe portion 14 are sandwiched from the front and back sides. This chuck 8 is opened by a chuck opening cam 12, and conversely closed by a chuck closing cam 9, and a chuck gap cam 10 widens the gap between the left and right chucks 8, 8. The structure for operating the check 8 will be described in detail below.

First, referring to FIG. 5, the left and right chucks 8,
The configuration related to opening and closing the interval of 8 will be described. Unit 5
A vertical rail 21 is fixed to the substrate 5a, and a movable base portion 22 is arranged on the vertical rail so as to be movable back and forth. At the center of the movable base portion 22, the chuck spacing cam 10 is erected upward. The movable base 22 is constantly urged forward (downward in FIG. 5) by a spring 23. A pair of arms 24 is provided on the left and right of the movable base 22.
Is rotatably attached. A chuck support 25 is rotatably provided at the tip of each arm 24.
The chuck supporting portion 25 is guided laterally (left and right) by a horizontal rail 26 fixed to the substrate 5a of the unit 5. Although not shown in FIG. 5, the chuck 8 is provided above the chuck support portion 25. Therefore, the movable base 22 is normally moved in the forward direction by the spring 23, and the distance between the left and right chuck support portions 25, 25 (and thus the distance between the chucks 8, 8) is expanded.

As shown in FIG. 4, a chuck spacing cam actuating piece 10x is provided in the vicinity of the front row 4a of the free flow conveyor so as to be movable back and forth by an air cylinder 10y. When the unit 5 approaches the chuck spacing cam working piece 10x by the free flow conveyor 4 and the chuck spacing cam 10 comes in front of the chuck spacing cam working piece 10x, the piston rod of the air cylinder 10y contracts, and the chuck moves. Interval cam actuation piece 10x
Moves backward and pulls the chuck gap cam 10 backward. As a result, the movable base 22 in FIG. 5 retracts, and the left and right arms 24,
By pulling 24, the distance between the left and right chuck supporting portions 25, 25 (and by extension, the distance between the left and right chucks 8, 8) is narrowed.

Next, with reference to FIG. 6, a configuration relating to opening and closing of each chuck 8 itself will be described. FIG. 6 illustrates the upper state of FIG. 5, in which the chuck 8 is mounted on each chuck support portion 25. The chuck 8 has a pair of front claws 8a and rear claws 8b and holds socks between the front claws 8a and the rear claws 8b. Front claw 8a and rear claw 8b
It suffices that at least one of them is movable, but in this embodiment, the front pawl 8a is movable, the rear pawl 8b is fixed, and the base of the rear pawl 8b is fixed to the chuck support portion 25. The front pawl 8a is rotatably attached to the front pawl holding portion 31 fixed to the chuck support portion 25. A connecting portion 8c is provided on the base of the front claw 8a so as to project therefrom.
In addition, the arm 32 is rotatably provided. The base end of the arm 32 is rotatably attached to the movable base 33.

The movable base 33 is guided forward and backward by a rail 34 provided below the movable base 33 so as to project above the chuck gap cam 10. The movable base 33 is constantly urged in the rearward direction (upward in FIG. 6) by the spring 35. Therefore, the movable base 33 is always urged in the rearward direction by the spring 35. Therefore, the front claw 8a of each chuck is always urged to rotate rearward (in the direction of closing the gap with the rear claw 8b).

The movable base 33 has a chuck opening cam 12
However, it is erected upward. Further, as shown in FIG. 3, a chuck closing cam 9 is rotatably provided on the column 20. This chuck closing cam 9
The locking portion 91 and the pressing portion 92 are formed into a substantially L-shape, and are pivotally supported by the support column 20 at the substantially L-shaped bent portion. The locking portion 91 engages with the upper end of the chuck opening cam 12 to allow the spring 35 to open the chuck opening cam 12.
To prevent each chuck 8 from being opened.

The pressing portion 92 is a portion that is pressed by a chuck closing operation piece 9x, which will be described later.
Is pressed, the locking portion 91 rotates upward,
The engagement with the chuck opening cam 12 is released, and the movable base 33 provided with the chuck opening cam 12 is retracted by the spring 35. As a result, each chuck 8
Is closed.

That is, as shown in FIG. 4, a chuck closing operation piece 9x is provided near the front row 4a of the free flow conveyor.
Is provided so as to be movable back and forth by an air cylinder 9y. When the unit 5 approaches the chuck closing operation piece 9x by the free flow conveyor 4 and the chuck closing cam 9 comes in front of the chuck closing operation piece 9x,
The piston rod of the air cylinder 9y extends, the chuck closing operation piece 9x moves forward, and the pressing portion 92 of the chuck closing cam 9 is pushed, whereby the locking portion 91 rotates upward, and the chuck opening cam. The engagement with 12 is released.
As a result, the movable base 33 of FIG. 6 is retracted by the spring 35, the left and right arms 32, 32 are pulled, and the front claw 8a of each chuck is rotated rearward to close the gap with the rear claw 8b. Close the chuck.

As described above, the gap between the left and right chuck support portions 25, 25 is widened to the left and right, and the chucks 8, 8 mounted on the chuck support portions 25, 25 are also moved left and right. Since it is biased in the closing direction by 35, the chuck 8 moves left and right while being biased in the closing direction.

Next, a method of inserting socks by this device will be described. The plurality of units 5 are spaced,
It moves on the free flow conveyor 4 and moves to the initial position (x in FIG. 1).
At a position indicated by (1), it is stopped by an appropriate stopper (not shown). In the state where the chuck opening cam 12 is stopped at this initial position, the chuck opening cam 12 is engaged with the locking portion 91 of the chuck closing cam, and the chuck opening cam 1 by the spring 35 is opened.
2 is prevented from retreating and each chuck 8 is kept open. The ascending cam 11 is in the free state, and the vertical rod 11a and the setting plate 6 are in the lower position. However,
The setting plate 6 is in a state of being rotated upward by the hinge 6a. The chuck gap cam 10 is in a free state, and the gap between the chucks 8 and 8 is equal to the spring 2
It is in a state of being spread by the biasing force of 3. However, at the stage of stopping at the initial position, the chuck spacing cam operating piece 10x
Is located in front of the chuck gap cam 10. Then, substantially simultaneously with the stop, the chuck spacing cam operating piece 10x
Pulls the chuck spacing cam 10 rearward. As a result, the left and right gaps between the chucks 8 and 8 are narrowed.

When the unit 5 is stopped at the initial position and the gap between the chucks 8 and 8 is narrowed, the operator puts the toes of the socks 13 on the setting plate 6 on the unit 5 as shown in FIG. Part 14 from above (toe part 1
(From the tip end side of 4), align the corner portion 16 of the toe portion 14 of the sock 13 with the setting point 7 of the setting plate 6. At this time, it is desirable to set the distance between the left and right setting points 7, 7 wider than the distance between the pair of corner portions 16, 16 of the toe portion 14 of the sock 13. That is, by setting it wide, the knitted fabric of the sock 13 is set in a slightly widened state, and the pair of corner portions 16 and 16 can be more accurately supported by the setting points 7 and 7. .

Next, the operator uses the hinge 6a to connect the setting plate 6 which is vertically rotatable.
And bring the setting plate down (Fig. 8). The sock 13 is in a state of hanging under the setting plate 6 with the toe portion 14 facing upward. In this state, the distance between the chucks 8 is narrowed, but the claws of each chuck 8 are open. That is,
The distance between the rear claws 8b, 8b of the left and right chucks 8, 8 is smaller than the lateral width of the setting plate 6, but the distance between the front claws 8a, 8a in the opened state is smaller than the lateral width of the setting plate 6. Also keeps a large interval,
The setting plate 6 includes left and right front claws 8a, 8a,
It is located between the left and right rear claws 8b and 8b. In the above state, the unit 5 starts moving on the free flow conveyor 4 and advances toward the guide slit 3.

When the unit 5 advances toward the guide slit 3, the chuck closing operation piece 9x pushes the pressing portion 92 of the chuck closing cam 9 to close the chuck 8 in the above-described manner. And eggplant More specifically, as shown by the chain double-dashed line in FIG. 8, the chuck 8 grasps the waste thread portion 17 of the corner portion 16 of the toe portion of the sock 13. During this time, the chuck gap cam 10 is pulled rearward by the chuck gap cam operating piece 10x,
Since the chuck interval cam moves forward along the cam operation piece 10x, the interval between the chucks 8 and 8 on the left and right is kept narrow.

When the unit 5 further advances toward the guide slit 3, the chuck spacing cam actuating piece 10x.
Moves forward to set the chuck gap cam 10 in a free state.
As a result, the urging force of the spring 23 causes the left and right gaps between the chucks 8, 8 to be wider than the lateral width of the setting plate 6, and brings the toe portion 14 of the supported sock 13 into a tensioned state (FIG. 9). More specifically, the pair of corners 1
The knitted fabric of the first stitch course 15 that connects between 6 and 16 is further widened.

When the unit 5 further advances toward the guide slit 3, the cam floor 11x rises to push up the ascending cam 11, and as shown by the arrow in FIG. Toe part 14
Get out of where you are

When the unit 5 further advances toward the guide slit 3, it rises from the cam floor 11x.
1, the vertical rod 11a and the setting plate 6 are lowered. An air cylinder 6x for rotating the setting plate is arranged diagonally opposite to the cam floor 11x across the free flow conveyor 4, and the piston rod of the air cylinder 6x extends to hang downward. The setting plate 6 that is being pushed up, from the hinge 6a to the setting plate 6
Rotate upwards.

Then, with the toe portion 14 of the sock 13 in a tensioned state, the unit 5 moves the toe sewing machine 2
The guide stitch 3 that connects the pair of corner portions 16 is inserted into the guide slit 3 from the side of one corner portion 16 while keeping a substantially straight line shape (see FIG. 10). ). As described above, the sock keeps the left and right tensions with a uniform force and the guide slits 15 in a state where the front stitching course 15 connecting the pair of corners 16 is aligned by the chucks 8 and 8. Since it is inserted while moving in parallel with 3, the good and accurate insertion state is always realized. still,
The sock 13 may be pulled downward at an appropriate position below the first stitch course 15. As a result, the knitted fabric of the front stitching course 15 can be in a tensioned state in the vertical direction as well, which enables better insertion. This pulling operation may be performed manually, or as shown by an arrow in FIG. 10, a piston rod of the air cylinder may be pressed downward at an appropriate position below the front stitching course 15 or a chuck may be performed. You may pick it up with and pull it downward.

When the sock 13 enters the guide slit 3, the chuck opening cam 12 on the unit 5 acts to open the chuck 8 and release the sock 13. More specifically, although not shown, a chuck opening operation piece that is operated by an air cylinder is provided near the free flow conveyor, and the chuck opening cam 12 is pushed forward. As a result, the chuck opening cam 12 is engaged with the locking portion 91 of the chuck closing cam, and the chuck opening cam 12 is prevented from retreating by the spring 35.
Open.

Thereafter, the unit 5 moves to the rear row 4b of the free flow conveyor 4 with the chuck 8 kept open, and moves toward the initial position x. On the other hand, socks are sewn by a toe sewing machine. Here, to summarize the work done by the worker, when the unit 5 stops at the initial position x, the toe portion 14 of the sock 13 is inserted into the setting plate 6, and at the same time, the corner portion 1 of the sock 13 is
6 is setting point of setting plate 6
Then, the setting plate 6 which is rotatably connected up and down is tilted to the front. Then, when a foot switch (not shown) is stepped on, the unit 5 with the socks 13 inserted
Begins to move. When the next unit 5 stops at the initial position x again, the same operation is repeated. In this way, the operator only has to perform the above-mentioned work, and the accurate insertion work can be automatically performed by only a simple work such as inserting the toe portion 14 of the sock 13 into the setting plate 6.

In addition to the above embodiments, the present invention can be carried out by appropriately changing it. For example, depending on the size of the socks, the pair of holding members (that is, the chucks 8 in the above embodiments) are separated from each other. It is also desirable to be able to adjust the interval. Further, the width of the setting member (that is, the setting plate 6 in the above embodiment) may be variable. In this case, the entire width of the setting plate 6 may be variable, but the setting points 7, 7
Is composed of a pair of bar members and the like, and the pair of bar members is provided so as to be slidable in the lateral direction with respect to the main body of the setting plate 6 so that the interval between the left and right setting points 7, 7 can be adjusted. May be. In order to make the lateral width variable, it is possible to adopt a structure in which two setting plates 6 are combined and the two members are slidably combined in the left-right direction. Further, in this way, by setting the entire lateral width of the setting plate 6 or the interval between the setting points 7 and 7 to be variable, the socks are inserted between the holding members 8 and 8 with the interval widened. After supporting the support members 8,
It may be removed from the gap.

In this embodiment, the unit is not provided with a driving means such as an air cylinder for operation, and the driving means is provided near the free flow conveyor 4, but it may be mounted in each unit. However, the number of driving means can be minimized by performing the method as in this embodiment. Further, the gist of the present invention lies in the movement of the chuck or the like, and the means for driving and transmitting the power thereof can be changed to various ones such as an electric motor, an electromagnet, a chain, a link and the like. In addition, the moving means of the unit can be changed to various moving means such as a free flow conveyor, other types of conveyors, screw feeding, etc., and the unit can be reciprocated without being circulated. You may make it exercise. Further, the chuck or the like may be moved by an appropriate moving means without using the unit.

Although the setting plate can be turned up and down, it may be left facing downward from the beginning. However, the workability is better when the sock is mounted so that it can be rotated up and down and the setting plate faces upward. Alternatively, the operator may directly support the chuck without using the setting plate. In this case, it is better to close the left and right chucks separately than to close them at the same time.

The chuck can hold other socks while keeping the sock tensioned, for example, another holding member, for example, a needle-like locking device that is projected to pierce the knitted fabric of the sock to hold it. Can be changed appropriately.
