Description

[Detailed description of the invention] (1) Industrial application field This invention relates to the structure of a machine that manufactures shoulder pads, which are one component of clothing.

(2) Conventional technology In order to manufacture shoulder pads, a needle punching device exclusively for the production of shoulder pads was devised, and in response to the mass production of ready-made clothing, needling was used to join and integrate cotton plates, allowing rapid mass production of shoulder pads. It corresponded to However, this device was large and heavy and was only used in factories.

(3) Problems that the invention aims to solve This invention proposes that the conventional needle punch device for manufacturing shoulder pads is suitable for use in factories;
Due to its large volume and heavy weight, it was difficult to use it in a cottage industry. Therefore, it became necessary to combine this needle punch device for shoulder pads with high production efficiency into a small, simple and light machine and use it in a cottage industry in order to flexibly manufacture shoulder pads, which have large fluctuations in demand. When demand grew, it became necessary to place small scale machines in each house and borrow the power of the cottage industry.

(4) Means to solve the problem A needle punch device for producing shoulder pads is compactly assembled into a small frame so that it can be used in home industry. A box is provided with an opening that continues to the base plate for entry and exit, an eccentric disc is provided on the box that is rotated by a motor, and the reciprocating motion is achieved by using the eccentric disc. Instead of the forward and reverse movement of the rotating shaft, the rod attached to the needle installation plate located near the opening of the box is changed to reciprocating motion by the up and down movement of a lever fixed to the rotating shaft, and the By transmitting the reverse motion, the ratchet type disc is rotated, and the main drum, which has a number of ribs close to each other around the outer circumference of the elongated body provided at the opening of the box, which receives the motion, is rotated intermittently. , the rotation of the main drum is transmitted to the feed drum and the delivery drum, and when the needle planting plate advances, the needles protrude between the brim of the main drum, and the main drum is stopped during that period.

(5) Function This device has the above-mentioned structure, so when the motor is activated, the rotation of the disk causes the needle planting plate to move forward and backward, and the eccentric disk causes forward and reverse movement of the rotating shaft. Instead of operating the ratchet type disc, when the needle planting plate moves forward, the main drum, feed drum, and delivery roller based on the action of the ratchet type disc stop, and when the needle planting plate moves back, the main drum, feeding drum, and feed roller stop. Let the drum and delivery roller rotate, and insert the shoulder pad material between the main drum and the delivery drum.
The main drum and the feed drum, which move intermittently, gradually bring the needle in front of the needle planting plate for needling, and then the needle is sent out from between the main drum and the feed roller.

(6) Example A box 4 is provided on the leg 1 with an opening 3 that continues to the base plate 2 for entering and exiting the shoulder pad material on one side and has an open bottom, and the rotation of the motor 5 provided on the leg 1 is controlled. Box 4
Transmission is transmitted to a disc 6 provided on the outside by a belt 7, the shaft 8 of the disc penetrates and crosses inside the box and projects outward on the opposite side, and an eccentric disc 9 is fixed to the protruding part of the shaft 8. One end of the rod 10 is rotatably attached to the eccentric part of the rod 9, and the other end of the rod 10 is rotatably attached to the tip of the lever 11.
The levers 13 and 13 are fixed to one end of the shaft 12 which has both ends protruding outside the box 4, and the levers 13 and 13 are respectively projected from both sides of the shaft 12 inside the box 4, and the rods 14 and 14 are attached to the tips of the levers 13 and 13. One end is rotatably attached to each, and both sides of the needle planting plate 15 are rotatably attached to the other end. Also, between the box side walls 16, 16 and the rods 14, 14, the box 4
Support rods 18, 18 are provided which horizontally and slidably pass through the protruding pillars 17, 17, respectively, and one end thereof is fixed to both sides of the needle planting plate 15 to support it. Furthermore, the root of the elongated hole arm 28 is fixed to the external protrusion of the case side wall 16 on the side opposite to the lever 11 mounting portion of the shaft 12, and one end of the rod 1 is inserted into the elongated hole of the arm 28.
The lever 22 of the ratchet gear 21 is attached to the shaft of the main drum 20 that protrudes outside the case of the main drum 20, which has a number of flanges fixed close to the outer periphery of an elongated cylindrical body, one end of which is rotatably attached and the other end of which is provided in the opening 3. Two feed drums 23, 23, which are rotatably attached to the tips and have flanges attached to the outer periphery of the elongated cylinder close to the lower side of the main drum 20 at a slight interval, are simultaneously connected by a chain inside the side wall 16 of the box. A delivery roller 24 is provided on the upper part of the main drum 20,
The outer protruding shafts of the box side wall 16 of the main drum 20, feed drum 23, and feed roller 24 are connected by a chain 25.

Since this invention has the above structure, the motor 5
When activated, the belt 7 rotates the disk 6, the shaft 8 rotates, the eccentric disk 9 also rotates, and the rod 10 is moved up and down, so that the tip of the lever 11 is raised or lowered. As a result, the shaft 12 rotates a little and then rotates back again. Lever 1 thereby fixing its root to shaft 12
3 and 13 are raised and lowered to raise and lower one side of the rods 14 and 14, so that the tips of the rods 14 and 14 move the needle planting plate 15 forward and backward.
Therefore, the needles 26 of the needle planting plate 15 pass through the front stripper plate 27 and connect to the main drum 2.
It protrudes or retreats between the tsuba of 0.
During this time, the needle planting plate 15 is supported by the support rods 18, 18. Also, by rotating the shaft 12 in forward and reverse directions,
The arm 28 swings its lower tip to the left and right and the rod 19
The lever 22 of the ratchet gear 21 moves diagonally left and right.
This causes the main drum 20 to be rotated intermittently by the ratchet gear 21. Thereby, by controlling the protruding direction of the levers 13, 13 of the feed shaft 12 and the mounting direction of the arm 28 at one end of the shaft 12, the levers 13, 13 of the shaft 12 can be controlled by the chain 25.
If the arm 28 is installed so that when the tip of the arm 28 rises and pulls the rods 14, 14 backward and the needle planting plate 15 retreats, the arm 28 pushes out the rod 19 and pushes the lever 22 of the ratchet gear 21. When the needle 26 is coming out of the shoulder patch material, the main drum 20, the feeding drum 23, and the feeding roller 24 rotate. Next, the shaft 12 is reversed, the rods 14, 14' are lowered horizontally, the needle planting plate 15 is advanced, and when the needle 26 pierces the shoulder patch material, the shaft 12 is reversed, and the tip of the arm 28 is 19 to ratchet gear 21
The lever 21 of the ratchet gear 21 is pulled in the opposite direction, and no force is applied to rotate the ratchet gear 21, so the main drum 20 stops, and the feed drum 23 and the feed roller 24 also stop. are doing. That is, the feed drum 23
The delivery roller 24 also rotates intermittently. Therefore, when the needle planting plate 15 moves forward, the main drum 20, the feeding drum 23, the feeding roller 24
has stopped rotating, and the needle planting plate 15 has stopped rotating.
When the main drum 20, the feed drum 23, and the feed roller 24 rotate. Therefore, when the shoulder pad material cotton board is inserted between the main drum 20 and the feeding drum, the material advances intermittently,
It advances between the stripper plate 27 and the main drum 20, is pierced by the needle 26 of the needle planting plate 15, is needled, becomes integrated, and gradually rises upward, and then the feed roller 24 and the main drum 20
It is sent out intermittently between the two.

(7) Effects of the invention In this invention, the necessary mechanical structure was packed into a small box, and the needle's movement, which was conventionally performed up and down, was changed to a horizontal direction, and a shaft that rotated in the forward and reverse directions using a single motor was created. Since the lever is raised and lowered to move the needle planting plate forward and backward, the needle planting plate can be moved forward and backward in a short distance, which helps to reduce the size of the box. When the loading drum and delivery roller are rotated and the needle planting plate is moving forward, the needle pierces the shoulder pad material, stops the main drum, delivery drum, and delivery roller, and needles the shoulder pad material. The shoulder pads that are made by wearing rings are made of tight cotton.

According to this invention, the structure is relatively simple, compact, lightweight, and easy to transport.
