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, as shown in Japanese Patent Publication No. 57-12641, has been used to feed successively fed button surface members 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 Application 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 invention shown in the figure, 10 is a main body;
1.12 is a guide member fixed to this main body; 13 is a passage formed by this guide member and extending in a predetermined direction;
14 is a rack attached along the lower inner surface of the guide member 12, and 15 and 16 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 denotes a surface member of the button, which has a retaining 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. This surface member 90 is supplied from a supply device (not shown) through the passage member 17 so as to cross the upper portion of the guide member 11 in a line. In fact, the surface member 90 has a directional pattern 93 formed thereon so that it can be attached to a material 95 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 passage 1
The main body member is configured to be moved forward and backward along the line 3 by means not shown, and is constructed by combining an upper member 20a, a lower member 2, and Ob. 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 a gear rotatably supported by the main body member 20 that meshes with the large-diameter tooth portion 24 of this gear 21; 26 is designed to mesh with this gear 25 and rotate at twice the rotation speed of the gear 21; The gear is fixed to a shaft 27 that 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 and has an uneven support surface 30. ing. Therefore, when the main body member 20 is moved along the passage 13, the support member 28 will rotate.

Reference numeral 31 denotes a lever-shaped movable member whose one end is 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 37 rotatably attached to its lower end. 38 is a wide part where the part near the front end of the movable member 31 is widened on both sides;
Reference numeral 9 denotes a pressing portion formed by recessing the lower surface of the center of the wide portion slightly upward into a conical cross section; 40 denotes a stopper holding portion consisting of a hole drilled slightly rearward from the pressing portion; 41;
．． Reference numeral 42 designates stopper holding portions that are formed by holes formed on both sides of the wide portion 38 from the center of the suppressing portion 38 in a direction perpendicular to the stopper holding portion 40, respectively. 43 is the stopper holding part 4
It is a pin-shaped stopper that can be selectively held at any angle of 0.41° or 42°, and is removably attached to the movable member 31 with a screw 46, and receives the elasticity of a bar-shaped presser spring 45. . This presser spring 45 is the stopper 4
Three pieces are prepared separately depending on which of the stopper holding parts 40, 41, and 42 will hold the pieces.

As shown by the solid line in FIG. 1, the front surface member 9 of the button at the tip has passed through the passage member 17 with the main body member 20 retracted.
0 is supported on the support member 28 and stopped, and in this case, the peripheral edge of the surface member 90 is almost the same as the main body member 28.
0 is in contact with the front end of the upper member 20a. 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
contacts 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 pair of side mounting devices, which are rotatably connected to the shaft member 51 and the main body 10 by a means not shown, and whose upper ends approach each other by means of a spring not shown. A claw 52 is provided, and a groove-shaped holding portion 55 is formed opposite to the winter melon. When the main body member 20 moves further forward from the above-mentioned state, the trochanter 3
7 reaches above the plate cam 16, the tip of the movable member 31 rotates toward the rear, the pressing portion 39 separates from the protruding portion 92, the stopper 43 separates from the retaining portion 91, and the surface member 90 is not pressed against the front end of the upper part 20a of the main body member 20, but is held between the holding parts 55 of the winter melon 52. After the main body member 20 retreats from this state, the attachment operation is performed.

When attaching the surface member 90 of a button as shown in FIGS. 8 to 10 to a workpiece 95, the surface member 90 will be as shown in FIG. a), (b), (C)
It is often installed in the direction shown. here 9
Reference numeral 6 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. Since it can be sent out toward the target, 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 may be attached to a member that can be rotatably fixed around the center of the suppressing portion 39 within a predetermined angle range, and the surface member 9o may be attached to the attached member 95 with the surface member 9o in a desired direction. Good too.
