Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a holding device for holding a button or a mounting member to a lower mold of a mounting device.

[Prior Art] Various devices for attaching buttons to clothes or fabrics have been proposed in the past. Among these, some use a feeding device that mechanically feeds the button or its attachment member to one or both of the upper mold and the lower mold, and holds the button or the attachment member at the correct position within the mold. That is, as shown in FIG. 1, a movable plunger 2 is supported on a frame 1 of the mounting device so as to be able to move up and down, and an upper mold 3 is provided at the lower end of the movable plunger 2. A lower mold 5 is provided in the lower mold 5 (in some cases, the lower mold is movable, and in some cases, the upper and lower molds are movable). a guide groove 6 horizontally aligned with these molds;
Guide members 8 and 9 having 7 are fixedly supported on the frame 1, and guide grooves of a button chute and a mounting member chute 11 are opened in these grooves, respectively. A well-known automatic button feeding rotary hopper or the like is connected to these chutes. A pair of brackets 12 (the other not shown) are fixed to the frame 1 at a horizontal distance, and guide rods 13 and 14 are supported between them. Guide rod 1
A sliding block 15 is movably supported at 3 and 14. This block is designed to be driven by a power source (not shown). Block 1
A pair of parallel pusher rods 16, 17 protrude from 5 and are adapted to slide in guide grooves 6, 7. In operation, when the plunger 2 is retracted, the block 15 is driven to the right and pushes the pusher rods 16, 17 to the right, thereby causing the buttons A and B falling from the chute 10, 11 and entering the guide grooves 6, 7. The mounting members B are pushed into the upper mold 3 and the lower mold 5, respectively. Before or at the same time as the plunger 2 is lowered, the pusher rods 16, 17 are retracted and the button A and the attachment member B are crimped together through the garment fabric.

FIGS. 2 to 4 show typical examples of conventional lower molds (for example, Japanese Patent Application Laid-open No. 81604/1983). In the lower mold, a columnar base 34 extends upward from a base 30 that is fixedly or cushioningly supported by the frame 1, and its upper end surface 33 is flat or recessed and serves as a receiving surface for a button or a flange of a mounting member. Further, the cylindrical inner surfaces of holders 36 and 37 fit into the cylindrical outer surface of the columnar base 34, and are guided in the vertical direction by pins 35 that fit into their slots 39 and 40. Further, the tapered upper end 43 of the ring 44 supports the tapered lower ends 41 of the holders 36 and 37. The ring is pushed upward by a spring 45 held by the collar 31, so that the holders 36, 37 can be elastically displaced in the mutual direction and in the upward and downward directions. The upper part of the cylindrical inner surface of the holder is formed slightly larger than the diameter of the button or the like to form a recess 38 for receiving the button or attachment member. In addition, the holder is the saucer 33
It has an inverted T-shaped slot 47 for guiding a button, etc. The button or attachment member consists of a large flange and prongs or legs and is generally in the shape of an inverted T.

[Conventional problems]

The button or mounting member is the pusher 17 shown in FIG.
is inserted into the top receiving surface 33 of the columnar base 34 through the inverted T-shaped slot 47. At this time, even if there is a slight difference in the size of the buttons etc., the holders 36, 37
There is no problem because it opens elastically to the left and right, but since the position of the inner wall on the back side of the slot 47 is fixed, if the stroke of the pusher 17 is not strictly fixed, the buttons etc. may not be in the correct position on the receiving surface. Don't stand still.
In this state, when the fabric is placed on the top surface of the holder and the upper mold holding the other party's buttons is lowered, the holder is pushed down and the buttons on the lower mold are exposed, but the upper and lower buttons are not correctly aligned. If they are not aligned, misalignment of the caulking position, deformation of the button, etc. often occur. This problem occurs not only with this type of lower mold, but also with similar ones.

Further, if the dimensions of the button or mounting member to be attached change, the lower mold (and the upper mold) must be replaced with another lower mold that matches the size. In the prior art, it was necessary to make adjustments each time according to the dimensions of the lower die, which was troublesome and inefficient.

[Purpose of invention]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a lower mold button or attachment member holding device that can be correctly attached to fabric such as clothing without strictly adjusting the supply of the button or attachment member. Another object of the present invention is to provide a retaining device that allows for correct installation without requiring precise adjustment of the position of the pusher.

[Summary of the idea]

The above object of the present invention is achieved by the lower die button or attachment member (hereinafter abbreviated as "button etc.") holding device of the present invention. That is, the button, etc. holding device of the present invention consists of a columnar base whose upper end serves as a receiving surface for a button, etc., and a single or two blocks that are attached to the periphery of the columnar base in a sliding manner and can move up and down. It consists of a holder, such as a button, whose part is provided with a guide slot, such as a button, and means for elastically biasing the holder upwards, characterized by an annular shape surrounding the receiving surface of the upper part of the holder. The inner wall is larger in diameter than the button, etc. due to the receiving surface, and tapers toward the upper end to a diameter slightly larger than the diameter of the button, etc.

Due to this feature, the button or the like pushed in by the pusher can be received in a relatively large space formed around the receiving surface, so that the pusher does not need to be adjusted every time the lower mold is replaced. The lowering of the upper die elastically presses the holder downward, whereby the button etc. are guided by the tapered surface of the holder and are naturally guided to the correct alignment position.

[Specific explanation of the idea]

Hereinafter, the present invention will be explained in detail by way of examples with reference to the drawings. In this example, the holder consists of one block, but the cylindrical inner surfaces of the holders 36 and 37 of the conventional structure shown in FIGS. 2 to 4 may be modified according to the principles of the present invention. Of course. However, the number of parts is reduced and the structure is simple.
The following examples are better.

Embodiment Figures 5 and 6 show a lower mold equipped with a holding device of the present invention. Details of the holding device are shown in FIG. 7 and subsequent figures. In these figures, parts common to those shown in Figs. 2 to 4 are indicated by the same symbols. However, in this example, the holder 50 is of a one-block type, and the ring 44 is not used.

The upper end of the base 30 is a collar 31 that supports a spring 45, and a cylindrical columnar base 34 extends above the collar 31, and the top serves as a receiving surface 33 for a button or the like. A holder 5 is attached around the upper end of the columnar stand 34.
0 is supported by a spring 45 so as to be able to slide up and down, and is further guided by vertical slots 39, 40 formed in the holder and a horizontal pin 35 fixed to the columnar base 34, and its vertical stroke is restricted. There is. The holder has an annular portion projecting above the receiving surface 33 to form a recess 38 for receiving and positioning a button or the like. Furthermore, an inverted T-shaped button-guiding slot 47 having a bottom surface parallel to or slightly higher than the receiving surface 33 is formed in the holder 50. The tip of the pusher is inserted into this slot 47.

7 to 10 are enlarged views of portions of the holding device of the present invention. The holder 50 is formed with a cylindrical inner wall having a diameter that slidably fits into the columnar base 34, and the diameter of the upper end opening 53 also matches this, and is slightly larger than the maximum diameter of the button, etc. . The bottom surface 51 of the inverted T-shaped slot 47 is preferably located at a position slightly higher than the receiving surface 33, thereby preventing buttons, etc. pushed in by the pusher from adhering to the tip of the pusher and being pulled back. Of the inner wall of the holder in the recess 38, the portion where the slot 47 abuts (or the portions on both sides thereof) is enlarged, and a tapered surface 52 is formed that gradually narrows from the bottom to the top.
is formed. This enlarged portion 54 is attached to the receiving surface 33 of the columnar base 34 so that there is play in the received button etc.
It is located almost in line with the plane of

[Effect]

The holding device configured as described above operates as follows. First, as mentioned in relation to Figure 1,
A button or the like is pushed into the recess 38 through the slot 47. As a result, buttons etc. can be placed on the receiving surface 3 at the top of the columnar base 34.
3 is sent above. At this time, since the diameter of the enlarged part 54 of the recess is larger than the diameter of the button, etc., there is play in the button, etc. Therefore, the adjustment of the tip of the pusher does not have to be precise, and the button, etc. It suffices if the stroke is sufficient to send it above 33.

Next, when the upper mold (see Figure 1) is lowered,
Its lower end engages with the upper end of the holder 50 through the fabric, lowering the holder against the spring 34. As a result, the buttons, etc. are pushed by the tapered surface 52 and are properly aligned on the receiving surface 33, and are correctly engaged with the fabric and the upper button, etc. through the opening 53,
Can be caulked.

As described above, it can be seen that according to the present invention, correct positioning can be achieved while allowing play in the buttons, etc. Therefore, there is no need to readjust the tip of the pusher every time the lower die is replaced.
