Description

[Detailed description of the invention] This invention has a simple structure that does not interfere with checking the hook feeding operation in an automatic hook punching machine, ejecting poorly installed hooks, etc., which causes radial wrinkles in the base fabric around the hooks. To provide a wrinkle prevention tool for a base fabric for attaching a hook, which can suppress wrinkles.

That is, a pair of driving tools facing each other in the vertical direction, and a pusher, etc., for feeding a male (or female) fitting member and a caulking member, which are the component parts of the male (or female) hook, are used. By lowering the upper driving tool with the base fabric for hook attachment inserted between the upper and lower driving tools, the needle-like protrusion protruding from the center of the crimping member penetrates the base fabric. and inserted into the center hole of the fitting member,
In an automatic hook-setting machine in which the tip of the needle-like protrusion is deformed to expand its diameter by impact and is caulked to the edge of the central hole, it is possible to attach the hook to the base material for attaching the hook, for example when attaching the hook to a raincoat. In some cases, when the needle-like protrusion of the crimping member is inserted into the center hole of the mating member, some of the fibers of the base fabric are brought into the center hole by the needle-like protrusion, and as a result, the fibers around the hook are Radial wrinkles may appear on the skin.

In view of these conventional drawbacks, the present invention is capable of preventing the above-mentioned radial wrinkles by being attached to the front of the driving tool below the automatic hook driving machine, and also allows for confirmation of the hook feeding operation by the pusher. We have developed a wrinkle prevention tool that does not interfere with the removal of improperly installed hooks.

Hereinafter, the present invention will be explained based on the illustrated embodiments.

The drawing illustrates a wrinkle prevention device A for a hook attachment base fabric according to the present invention, and the wrinkle prevention device A includes a horizontal ring portion 1 on which a hook attachment base fabric B is placed, and a downward portion from a part of the circumference of the ring portion 1. The vertical plate portion 2 extends to form a substantially inverted L-shaped side surface, and a rectangular through hole 3 larger than the hook is formed at the upper end of the vertical plate portion 2, and a mounting hole 3 is formed in the center. A stepped hole 4 is formed for inserting a screw. Further, the upper surface of the ring portion 1 and the inner and outer peripheral surfaces are appropriately rounded.

As shown in FIG. 1, the wrinkle prevention tool A described above is
It is used by being attached to the front surface of a lower driving tool 5 in an automatic hook driving machine with a screw 6.

Then, as shown in FIGS. 6A and 6B, with the base fabric B placed on the ring part 1, by performing the hook punching, the base fabric B is moved inside the ring part 1 by the fitting member 7. The fitting member 7 is recessed in a substantially inverted conical shape and is evenly stretched over the entire circumference of the fitting member 7. In this state, the needle-like protrusion of the caulking member 8 penetrates the base fabric B and is inserted into the center hole of the fitting member 7, and is struck by the hammer 9a of the upper driving tool 9 to caulk the edge of the center hole. be stopped.

Therefore, even if the base fabric B is a fabric such as a raincoat, radial wrinkles do not occur around the hooks.

Also, since a through hole 3 is formed at the upper end of the vertical plate portion 2 of the anti-wrinkle tool A, the crimping member 8 is fed onto the die 5a of the lower driving tool 5 by the pusher 10. This can be visually confirmed through the through hole 3. In addition, if the needle-like protrusion of the caulking member 8 does not penetrate the base fabric B for some reason, or if you perform a trial punch without inserting the base fabric B prior to the stitching operation, the die The crimping member 8 on 5a can be pushed out of the machine from the through hole 3 by the next crimping member fed by the pusher 10, and the vertical plate portion 2 of the wrinkle preventer A pushes the crimping member 8 out of the machine. does not interfere with the feeding operation.

In the figure, 9b is a chuck that holds the fitting member 7 in a constant position, and the chuck 9b and the hammer 9
The upper driving tool 9 is constituted by a.
11 is a chute, 12 is a pusher that feeds the fitting member 7 that has flowed down to the lower end of the chute 11 into the chuck 9b, and 5b is a chuck that holds the caulking member 8 in a constant posture, and the chuck 5b and the die 5a It constitutes the lower driving tool 5.

Although the drawing shows a male hook made of synthetic resin consisting of a male fitting member 7 and a caulking member 8, a female hook consisting of a female fitting member and its caulking member is shown. However, the structure and function of the anti-wrinkle tool A are no different from those shown in FIG. Furthermore, the wrinkle prevention tool A of the present invention relates to an automatic hook driving machine that performs so-called reverse driving, in which a fitting member is fed into the lower driving tool 5 and a caulking member is sent into the upper driving tool 9 to perform the hook driving. Of course, it can also be applied in the same way.

The anti-wrinkle device according to the present invention has the above-mentioned configuration, so that when used by being attached to the front of the lower driving tool in an automatic hook driving machine, the base fabric will move inside the ring part as the upper driving tool descends. Since it is recessed into a substantially inverted conical shape and stretched uniformly over the entire circumference of the ring portion, it is possible to prevent radial wrinkles from forming around the hook. Moreover,
The vertical plate that supports the ring part has a through hole larger than the hook formed at its upper end, so you can visually check the hook feeding operation by the pusher from this through hole, and you can also check the test hooks and This has the effect that the vertical plate part does not get in the way when discharging a poorly installed hook forward with a pusher.
