Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a button mounting direction setting device for setting the direction of a button in one of a plurality of predetermined directions when the surface member of the button has directionality in a button mounting machine. be.

Conventionally, this type of device is shown in Japanese Patent Publication No. 57-12641, in which button surface members that have been continuously fed are sent out one by one along a predetermined path. A device is known in which a part of the mounting device for mounting on a device or the like can be rotated by a predetermined angle to obtain a desired orientation. A similar device is also disclosed in Japanese Patent Laid-Open No. 58-8107. However, both methods have the disadvantage that the surface member of the button is rotated in the attachment device, making the device complicated.

The present invention solves this problem by selecting one of a plurality of directions and setting the surface members to face that direction when sending out the button surface members one by one and supplying them to the mounting device. The present invention provides a button mounting direction setting device.

An embodiment of the present invention will be described below with reference to the drawings.

In one embodiment of the present invention shown in the figure, 10 is a main body, 11 and 12 are guide members fixed to the main body, 13 is a passage formed by the guide member and extends in a predetermined direction, and 14 is a passage of the guide member 12. Racks 15 and 16 attached along the inner surface of the lower portion are plate cams attached to the rear and front portions of the main body 10 at the lower center of the passage 13, respectively. Reference numeral 90 designates a surface member of the button, which has an engaging portion 91 formed by cutting out a portion of its inwardly bent peripheral edge, and a cylindrical protruding portion 92 extending upwardly in the center thereof. The surface members 90 are supplied from a not-shown supply device through the passage member 17 in a line across the upper portion of the guide member 11. Further, the surface member 90 has a directional pattern 93 formed thereon so that it can be attached to a material 95 to be attached, such as cloth, in conjunction with a back member (not shown).

Reference numeral 18 denotes a button attachment direction setting device which also serves as a transfer device, and is constructed as described below. That is, 20 is a main body member which is moved forward and backward along the passage 13 by means not shown, and is constructed by combining an upper member 20a and a lower member 20b. A gear 21 is attached to a vertical shaft 22 that is rotatably supported by the main body member 20, and has a small-diameter tooth portion 23 on the lower side that engages with the rack 14 and a large-diameter tooth portion 24 on the upper side. 25 is this gear 2
A gear 26 is rotatably supported by the main body member 20 that meshes with the large diameter tooth portion 24 of the gear 25, and is designed to mesh with the gear 25 and rotate at twice the rotation speed of the gear 21. , is fixed to a shaft 27 which is rotatably supported by the main body member 20, and the upper part of this shaft is integrated with a support member 28 whose upper surface is slightly concave to form a support surface 30 with projections and depressions. Therefore, along the passage 13, the main body member 20
When the support member 28 is moved, the support member 28 rotates. A lever-shaped movable member 31 has one end rotatably connected to the main body member 20 by a pin 32, and is always pulled by a helical spring 33 so that its tip points downward. Reference numeral 35 denotes a shaft member whose upper end is connected to the movable member 31 by a pin 36 and which extends downward, passing through the main body member 20 and having a trochanter 3 at its lower end.
7 is rotatably mounted. 38 is the movable member 3
A wide part where the part near the front end of 1 is widened on both sides,
39 is a pressing portion formed by recessing the lower surface of the center of the wide portion slightly upward and having a conical cross section;
0 is a stopper holding part made of a hole drilled slightly behind this pressing part, and 41 and 42 are holes made on both sides of the wide part 38 from the center of the pressing part 38 in a direction perpendicular to the stopper holding part 40. This is a stopper holding part. 43 is a stopper holding part 40,4
A pin-shaped stopper that can be selectively held in any of the positions 1 and 42, and a rod-shaped presser spring 4 that is removably attached to the movable member 31 with a screw 46.
It is designed to receive the elasticity of 5. This presser spring 45 holds the stopper 43 in the stopper holding portions 40 and 4.
Only three pieces are prepared separately depending on whether they are to be held in either number 1 or number 42.

As shown by the solid line in FIG. 1, the front end button surface member 60 that has passed through the passage member 17 with the main body member 20 retracted is supported on the support member 28 and stopped. Surface member 9
The peripheral edge of 0 is approximately the upper member 20a of the main body member 20.
It is designed to touch the front end of the Further, in this state, the tip of the movable member 31 is rotated upward by the plate cam 15 so that the pressing portion 39 and the stopper 43 do not come into contact with the surface member 90. When the main body member 20 is moved forward from this state, the surface member 90 moves forward while rotating together with the support member 28. Further, the leading end of the passage member 17 is blocked by the main body member 20 to prevent the surface member 90 from moving forward. When the main body member 20 moves forward and the movable member 31 reaches the position shown by the chain line in FIG. 39 presses the protrusion 92 of the surface member 90, and the stopper 43 touches the peripheral edge of the surface member 90 and presses it lightly, so that the surface member 90 continues to rotate together with the support member 28 even in this state. When the main body member 20 moves further forward, the lower end of the stopper 43 comes to be above the engaging part 91 and engage with it. When the stopper 43 engages with the engaging portion 91, even if the support member 28 rotates, the surface member 90 moves forward without rotating.

Reference numeral 50 denotes a lower part which is disposed in front of the main body 10 and is attached to a material to be attached 95 such as cloth by combining the front surface member 90 of the button and the back member of the button supplied from the upper part in cooperation with an upper attachment device (not shown). A shaft member 5 that is raised and lowered by a means not shown in the drawings using a side mounting device.
A pair of claws 52 are rotatably connected to the main body 1 and the main body 10 by a pin 53, and the upper ends thereof are brought close to each other by a spring (not shown). A holding portion 55 is formed. When the main body member 20 moves further forward from the above-mentioned state, the trochanter 37 reaches above the plate cam 16, and the tip of the movable member 31 rotates upward, thereby pressing the pressing portion 39.
is separated from the protruding portion 92 and the stopper 43 is separated from the engaging portion 91, and the surface member 90 is held between the holding portions 55 of each claw 52 while being pressed against the front end of the upper member 20a of the main member 20. It turns out. After the main body member 20 retreats from this state, the attachment operation is performed.

Button surface member 9 as shown in FIGS. 8-10
0 to the workpiece 95, the surface member 90 may be attached to the 11th or
It will be installed in the directions indicated by a, b, and c in the figure. Here, reference numeral 96 indicates the edge portion of the material to be attached 95 facing the button attaching machine.

As described above, in this invention, the stopper 43 can be held in the movable member 31 by changing the arrangement of the stopper 43 at a plurality of locations, so that when the button surface member 90 is delivered to the mounting position, the stopper 43 can be moved in a desired direction. Since it can be sent to any direction, it has the effect of being significantly simpler in structure than conventional devices of this type.

Note that various modifications can be made to this invention. For example, the stopper 43 can be attached to a member that can be fixed rotatably around the center of the pressing part 39 within a predetermined angle range, and the surface member 90 can be attached to the attached member 95 with the surface member 90 in a desired direction. Good too.
