Description

[Detailed description of the invention] [Industrial field of application] This invention relates to an automatic sock tensioning device that tensions socks into an embroidery frame when performing one-point embroidery on the leg side of socks using an embroidery sewing machine. .

[Conventional technology]

The one-point embroidery on the side of the leg of the sock is done with high efficiency using a multi-head embroidery machine. To load socks into the embroidery machine, as shown in Figure 6,
One side N of the leg part of the sock S to be embroidered is held under tension using an oval inner frame X and an outer frame Y. P
is a piece of batten paper.

A conventional automatic sock tensioner for loading socks into an inner frame X and an outer frame Y, as shown in FIGS.
It consists of a movable piece 34 equipped with a sock locking pin 33 that moves forward along a groove 32 on the lower surface of the arm 31,
A planar oval recess 35 for frame insertion is provided at the top end of the arm 31, and the cylindrical leg F is inserted into the arm 31 with the inner frame X fitted into the recess 35, and the inner frame Fit the outer frame Y and hold one side N,
The knitted fabric is locked with a pin 33, and as the movable piece 34 moves forward, the leg part F is moved and bundled, and the extra knitted fabric of the leg part is inserted into the gap between both frames.

[Problem that the invention attempts to solve]

However, in this conventional automatic sock tensioner, since the knitted fabric is pulled by inserting pins into it, pin holes may be made or the knitted fabric may be torn.
To simply press and slide the knitted fabric, the knitted fabric bends and folds in a zigzag pattern (see arrow A in Figure 9), becomes bulky and stores elasticity, and is pushed into both frames, and then the frame is removed by some force. There were problems such as easy falling off.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention provides a planar oval shaped recess for frame insertion at the front end of the upper surface of the arm to be inserted into the sock leg, and a flat oval recess for inserting the frame into the lower surface of the arm. There is one in which a knitted fabric winding belt of a required length is installed in a hanging manner, and a belt engaging roller that moves back and forth is attached between the lower surface of the arm and the belt.

[Effect]

According to this idea, when the sock leg is fitted into the arm containing the belt, the knitted fabric comes into close contact with the belt due to its shrinkage elasticity, and when the roll is moved back and forth, the wavy belt wraps the maki-zushi. As before, the knitted fabric is rolled up from the end (see arrow B in Figure 4), and the front end of the arm is automatically fitted into the recess between the flanges of both frames.

The knitted fabric is not damaged because the belt only comes into contact with it, and the knitted fabric is wound in a spiral shape and has a low bulk, so that the elasticity of contraction acts on the knitted fabric, so that it does not fall off from the frame.

〔Example〕

1 to 5 show an embodiment of this invention. The automatic sock tensioner of this invention is
As shown in FIGS. 1 and 2, the leg part F of the sock S
(See Figure 3) Elongated prismatic arm 1 inserted into
A planar oval recess 2 for frame insertion is provided at the front end of the upper surface, and a front end fixing point 3 for the arm 1 is provided at the lower surface of the arm 1.
A knitted fabric winding belt 5 of a required length is suspended between the rear end fixing point 4 and the rear end fixing point 4, and the belt moves back and forth via a crank mechanism 6 between the lower surface of the arm 1 and the belt 5. An engaging roller 7 is provided.

The arm 1 is slightly larger than the leg cylinder of the sock, and when inserted into the leg, the knitted fabric comes into close contact with the sock.

The inner frame X is first fitted into the recess 2, and after the socks are fitted, the outer frame Y is fitted from the outside to hold the socks. A space 8 (see FIG. 3) is formed between the flanges of both frames into which the rolled up knitted fabric is inserted.

The belt 5 has a sufficient length and is suspended along the arcuate locus of the roller 7 (see chain line c in Figure 1) that swings around the spindle 9 of the crank mechanism 6. When the sock is put on, it will sag backwards (see Figure 3), and as the roller moves forward along the arcuate trajectory of the roller 7, the knitted fabric will be rolled up from the end, like winding a sushi.

The crank mechanism 6 consists of a crank rod 12 attached to a rotary plate 11 of a deceleration motor 10, and a lever 13 that connects the end of the crank rod 12 and a roller 7 and swings about a support shaft 9. It is stopped by operating the switch 14. Leverage 13
On the other hand, the roller 7 is rotatable.

When using the automatic sock tensioner, as shown in FIG. 3, the roller 7 is moved backward and the inner frame X is fitted into the recess 2 of the arm 1, and the leg part F of the sock S is fitted into the arm. The side surface N to be embroidered is aligned with the inner frame X, and the outer frame Y is fitted and fixed from the outside.

Next, as shown in FIG. 4, when the foot switch 14 is stepped on to drive the crank mechanism and move the roller 7 forward, the roller 7 comes into contact with the belt 5 and ripples it as it rotates, thereby winding the knitted fabric from the edge. As shown in FIG. 5, when the roller 7 moves forward to the frontmost end, the rolled up knitted fabric falls into the space 8 between the flanges of both frames by the shrinkage elasticity of the knitted fabric itself, and loading is completed.

(See Figure 6) The automatic sock tensioner of this invention can be manufactured and sold as a stand-alone unit, or can be attached to an automatic sock embroidery setter as shown below.

FIG. 7 shows an embodiment in which this invention is installed in an autosetter for embroidering socks. Rotating shaft 15
Six radial arms 16 are fixed to the radial arm 16, and while the whole unit rotates intermittently (see the direction of the arrow), a piece of paper P is supplied to the tip of the arm 16 at position A, and the inner frame X is superimposed on the piece of paper at position B. At position C, the sock S is inserted through the opening and set. At position D, the outer frame Y is supplied. At position E, the embroidery consisting of the belt 5, crank mechanism 6, roller 7, etc. of the present invention is carried out. An automatic sock tensioning device is attached to the frame, and the intermittent rotation of the arm is automatically operated to wind the socks around the frame body and tension the socks.

〔effect〕

As mentioned above, the automatic sock tensioner according to this invention uses a belt with sufficient length, and uses a roller that moves the belt back and forth to wave the belt and sequentially wave it, like when winding sushi rolls. Since the knitted fabric is moved while being rolled up with a belt and pushed, there is no damage to the knitted fabric as in the conventional example, and the knitted fabric is rolled up in a winding shape. Because of its low bulk, when it is fitted into the outer periphery of the frame, combined with the shrinkage elasticity of the knitted fabric itself, there is an effect that it will not fall off from the frame.
