Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a marking light for use in a button attachment device.

[Description of prior art]

Conventionally, when attaching a button member to clothing fabric using a button attaching device comprising upper and lower dies each holding a button member, an optical system is used to accurately attach the button member to a predetermined position on the clothing fabric. An expression pointer is used. The optical pointer typically consists of a cylindrical member having a light source and a light path therein, and light from the light source is led out from a small hole at the tip of the cylindrical member, and the light is directed to the mounting position. Displays the button mounting position of the positioned mounting fabric.

For example, Utility Application No. 58-200487
No. 113322) discloses a mounting position display device in which an optical pointer is integrally provided with a pusher that pushes one of the button members in the horizontal direction. In the device, the tip of the pointer is positioned above the center of the button mounting position when the pusher is fully advanced. A similar structure is from Tokugansho.
It is also described in No. 51-12403 (see JP-A No. 52-13943). However, in a mounting position display device having such a configuration, it is generally necessary to extend the tip of the optical pointer beyond the center of the button mounting position, and on the other hand, since the return stroke of the pusher is constant, the pointer must be made quite elongated. Since the return speed of the pusher is also constant, the mounting height position between the upper and lower dies must be adjusted to avoid collision between the upper die, which descends as the plunger descends, and the tip of the pointer. must also be examined.

Therefore, in a conventional button attachment device using such an optical pointer, when the button members are tightened together during the button attachment operation, the optical pointer collides with the upper die that descends with the plunger of the device. Various methods have been devised to avoid this. However, since such a device is based on the premise that the optical pointer will not collide with the plunger as mentioned above, it is necessary that the optical pointer be able to move away from the plunger at a speed faster than the return speed of the pusher. A special mechanism is provided either integrally with the pusher or separately in association with the pusher, thereby complicating the overall structure of the mounting position display device.

[Purpose of invention]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a mounting position indicating device with a simple structure.

Another object of the present invention is to provide a mounting position indicating device comprising an optical pointer configured to always collide with the plunger during return operation.

[Summary of the idea]

According to the present invention, a slender optical pointer member for displaying a button mounting position in a button mounting device, and a holder member that is slidable in the horizontal direction by a pusher of the button mounting device are provided. a holder member having one end of the optical pointer member swingably attached; and an urging force interposed between the elongated optical pointer member and the holder member to urge the optical pointer member upward. A direct marking light is provided. When the direct marking light of the present invention is activated, the pusher of the button mounting device is forced horizontally in the direction of the plunger, i.e. forward, at the same speed as the pusher, and is also pushed horizontally by the pusher at the same speed as the pusher. is returned to the rear rest position at a speed of . At that time, the tip of the marking light collides with the descending plunger, but an escape mechanism provided at the rear end of the marking light prevents the tip of the marking light from being destroyed by the plunger. Return to rest position.

[Explanation of Examples]

The present invention will be described in detail below with reference to the drawings. Please refer to Figure 2. The direct marking light 10 of the present invention is installed adjacent to the plunger 14 of the button attachment device 12, a portion of which is shown. The direct marking light 10 generally includes a cylindrical member 16 having a light source and a light path therein, and a button mounting device 12 that supports the cylindrical member and allows the direct marking light 10 to slide freely. It consists of a holder member 18 that serves as a support for attachment. Light from the light source is emitted from a small hole 20 at the tip of the cylindrical member, and the light indicates the button attachment position on the attachment fabric along a button attachment position line 22. The rear end of the tubular member 16, ie the end remote from the plunger 14, is rotatably connected to the holder member 18 by support means 24, preferably a rod member.
Further, between the coupling portion and the holder member,
A biasing means 26, preferably a spring member, is provided for biasing the tubular member 16 upwardly.
The biasing means 26 has one end coupled to a portion of the cylindrical member 16 via the support means 24;
The other end is engaged with one end of the holder member. The holder member 18 is preferably provided integrally with a pusher 28 of the attachment device 12 or is attached to the device 12 in such a way that the same movement as that of the pusher is achieved and is directed by arrow A relative to the plunger 14 of the device 12.
As shown in the figure, it can freely slide in the front and rear directions.

Please refer to FIGS. 2 and 3. In operation, the pusher 28 first pushes one member of the combination button member (not shown) toward the plunger 14 through the passage 30, and at the same time, the holder member 18, that is, the direct marking light 10 is moved by the pusher 28. Then, it is pushed toward the plunger 14. Next, the position of the small hole 20 at the tip of the cylindrical member 16 is aligned with the button attachment positioning line 22, and positioning light is led out from the small hole 20. When the attachment position is confirmed, the pusher 28 starts to retreat in the direction of arrow D (see FIG. 3), and at the same time, the direct marking light 10 is also retreated. Meanwhile, the plunger 14 of the device 12 is lowered along the attachment position line 22 in the direction shown by arrow B in FIG. come into contact with However, at that time, the cylindrical member 16 rotates downward as shown by arrow C around the support means 24 at the rear end and escapes. is not transmitted. The direct marking light 10 continues to be retreated in the direction of arrow D with the plunger 14 still in contact with the tip of the cylindrical member 16, and eventually the cylindrical member separates from the plunger 14. At that moment, it is resiliently returned to the upper position by the force applying means 26 disposed at the rear end. The plunger 14 continues to descend even after the cylindrical member 18 is separated, and the attachment of the button member is completed.

Although the invention has been described with reference to specific examples, it should be remembered that many modifications may be made thereto.
