Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a button conveying device in a button attaching machine for attaching snap buttons, caulking buttons, etc. to clothing fabrics.

Prior Art As shown in Japanese Unexamined Patent Publication No. 56-85407, a button in a first hopper is supplied to a lower mold unit equipped with a crimping die by a button conveying device, and a button mounting tool in a second hopper is supplied. is supplied to an upper unit equipped with a crimping punch using a conveyance device, and by operating the crimping punch with the clothing fabric facing between the upper and lower units, it penetrates the clothing fabric and swages the button and button fixture. A button attaching machine is known that connects buttons to attach them to clothing fabric.

On the other hand, when attaching a button with characters, figures, etc. drawn on the surface to clothing fabric, it is necessary to always attach the button in a specified direction, and the button conveying device is attached to the lower mold unit with the button in the specified direction. We are making it possible to supply the following.

For example, as shown in Japanese Patent Application Laid-Open No. 52-28453,
At the top of the base, one side guide member having a wedge-shaped groove and the other side guide member having a vertical wall are arranged facing each other to form a button conveyance path where the circular head of the button faces, and the one side guide member is biased toward the other side guide member by a spring, and when the button is conveyed by a pusher along this button conveyance path, the sliding resistance between the circular head of the button and the wedge-shaped groove is applied to the circular head of the button. The button is rotated in one direction by being greater than the sliding resistance between the button and the wall, and
A button conveying device is known in which a projection is formed on the back surface of the circular head of the button, and this projection is brought into contact with a receiving portion of a guide member on one side so that the buttons can be oriented in the same direction.

Problems to be Solved by the Invention In this button conveying device, when the button is conveyed along the button conveying path, the button rotates, and one of the protrusions of the circular head comes into contact with the receiving part of the guide member on one side. Since the buttons are oriented in the same direction and then the buttons are transported while the protrusions slide along the receiving portions, the protrusions of the buttons and the receiving portions of the one-side guide member may be damaged. In addition, the button is conveyed while rotating until the projection of the button hits the receiving part of the one-side guide member, and its circular head is sequentially pushed into the wedge-shaped groove, and the pushing force causes the one-side guide member to act as a spring. However, since the entire guide member on one side is moved, the circular head of the button is pushed into the wedge-shaped groove with a strong force, and the button moves after a large pushing force is applied. The sliding resistance between the button and the groove may become large, making it impossible to rotate the button smoothly while transporting it.

Means and operation for solving the problem A first guide member having a wedge shape is slidable along the top surface of the base in a direction perpendicular to the button conveyance path.
Consisting of a member and a second member fixed to the base,
The first member is slidably biased and held toward the other guide member, and a locked part and a locking part are provided that engage with the circular head of the button and the pusher. When the button rotates, the locking part of the pusher and the circular head of the button engages with the locked part, making the buttons in the same direction.After that, the button is conveyed by the pusher without rotating, and When the circular head rotates and is pushed into the wedge-shaped groove, the first member slides with a small pushing force to prevent the circular head of the button from being pushed into the wedge-shaped groove with a strong force. .

Embodiment FIG. 4 is a schematic diagram of a button mounting machine, in which an upper mold unit 2 equipped with a crimping punch 1 that is moved up and down by a lifting mechanism (not shown) and a lower mold unit 4 equipped with a crimping die 3 are placed facing each other. The exit side of the first hopper 6 in which the button fitting A is housed is the first hopper 6.
The outlet side of the second hopper 9 in which the button B is housed is connected to the lower unit 4 via a second chute 10 and a button conveyor 11. In addition, the first and second hoppers 6 and 9 are configured to sequentially transport the button fixtures A and B one by one, as shown in, for example, Japanese Patent Application Laid-Open No. 56-85407.

As shown in FIG. 5, the button B has letters on the surface.

A hole 15 is formed, and the button is attached to the clothing fabric by fitting an engaging rod 16 of the button fixture A into the hole 15 through the clothing fabric C and crimping it.

As shown in FIG. 3, the button conveyance device includes a conveyance guide section 20 and a pusher section 21, and the conveyance guide section 20 is provided with a one-side guide member 24 having a wedge-shaped groove 23 on the upper surface of one side of a base 22. , the other side guide member 26 having a vertical wall 25 is provided on the upper surface of the other side to form a button conveyance path 27 extending in the longitudinal direction, in which the circular head 12 of the button B faces.
1 is a main body 29 having an upward U-shaped guide groove 28;
A pusher 30 is slidably provided on the pusher 30, a finger 31 is attached to the pusher 30 with a pin 32 so as to be slidable up and down, and a protrusion 34 is provided which is biased to swing clockwise by a spring 33 and becomes a locking part. The tip portion is held downward, and the pusher 30 is connected to a moving mechanism (not shown), such as a cylinder or a reciprocating link. Note that the vertical wall 25 of the other side guide member 26 may not be vertical but may be inclined if it guides the circular head 12 of the button B.

The base 22 has a substantially rectangular parallelepiped shape, and has a bolt hole 41 formed on one side 22a, a rising piece 42 integrally formed on the other side, and an opening 43 formed therein. Side guide member 2
The protruding piece 44 of No. 6 faces and is swingably supported by a pin 45, and a spring 47 is provided between the screw rod 46 screwed into the rising piece 42 and the other side guide member 26.
is provided, and the other side guide member 26 is biased to swing around the pin 45.

The one side guide member 24 has a first member 50 and a second member 50.
The first member 50 has a thin plate shape, and has a vertical surface 52 and an inclined surface 53 formed on one end surface, and is perpendicular to the button conveyance path 27 on the upper surface 22b of the base 22. A sliding resistance is provided in the direction.

The second member 51 has an L-shaped plate shape with a vertical piece 55 and a horizontal piece 56, and the lower thick part 5 of the vertical piece 55
A bolt 58 is screwed into the threaded hole 41 through the through hole 57 formed in 5a, and is fixed to one side 22a of the base 22, and the upper thin part 55b of the vertical piece 55 and the other side 50b of the first member 50 are connected. A gap _S1 is formed between the upper thin part 55b and the first member 5.
A spring 59 is provided between the first member 50 and the first member 50 to the right, and the bent piece 60 is attached to one side 22a of the base 22.
The lower surface 5 of the horizontal piece 56 of the second member 51
6a is in contact with the upper surface 50a of the first member 50, and the vertical surface 52 and the inclined surface 53 form a wedge-shaped groove 23.

However, the button B is closer to the main body 2 than the second chute 10.
It falls into the guide groove 28 through the notch 29a of No. 9, and is set so that the mounting rod 13 faces upward.

When the pusher 30 is moved in the direction of the arrow, its thin plate-like tip surface 30a comes into contact with the circular head 12 of the button B and is pushed toward the button conveyance path 27.

At this time, the finger 31 swings slightly clockwise about the pin 32 against the spring 33 because the protrusion 34 contacts the back surface of the button B.

When the button B is pushed into the button conveying path 27, the circular head 12 comes into contact with the wedge-shaped groove 23 and the vertical wall 25, and the sliding resistance is greater at the contact part with the wedge-shaped groove 23, so the button B The button is conveyed along the button conveyance path 27 while being rotated in one direction by the pushing force of the pusher 30.

As a result, the notch 14 formed on the back side of button B
Since the button B matches and fits with the protrusion 34 of the finger 31, the orientation of the button B becomes a predetermined direction, and after that, the button B is conveyed by the pusher 30 without rotating and is inserted into the crimping die 3 of the lower die unit 4. Since the supply is always set in a predetermined direction, the button conveyance path 27 and the circular head 12 of the button B will not be damaged.

On the other hand, since the circular head 12 is sequentially pushed into the wedge-shaped groove 23 when the button B is conveyed along the button conveyance path 27, the one side guide member 24 is not connected to the button conveyance path 27.
A force perpendicular to and in a direction of separation is applied, and the first member 50 of the one-side guide member 24 slides along the upper surface 22b of the base 22 against the spring 59.

At this time, since only the first member 50 forming the wedge-shaped groove 23 is slid, the one-side guide member 2
Since the first member 50 slides with a small pushing force compared to the case where the entire button B slides, when the circular head of the button B is pushed into the wedge-shaped groove 23 with a weak force, the first member 50 slides smoothly. The sliding resistance between the wedge-shaped groove 23 and the circular head 12 does not increase, and the button B can be smoothly conveyed while being rotated.

[Effect of idea]

When the circular head 12 of the button B is pushed and rotated by the pusher 30 while being conveyed along the button conveying path 27,
The locked part of the circular head 12 of button B and the pusher 30
The button B engages with the locking part, and the direction of the button B becomes constant.
Thereafter, the button B is pushed by the pusher 30 and transported without rotating, so that the button transport path 27 and the circular head 12 of the button B are not damaged.

When the circular head of the button B is pushed into the wedge-shaped groove 23 while rotating and conveying the button B, the first member 50 resists the force and moves away from the other guide member 26 with a small pushing force. Since the button B slides smoothly, the circular head 12 of the button B is not pushed into the wedge-shaped groove 23 with strong force, and the sliding resistance between the circular head 12 and the wedge-shaped groove 23 is not increased, and the button B It can be transported smoothly while rotating.
