Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to a clamping tool attachment machine, and more specifically to a clamping tool for clamping flexible objects such as cloth products, leather products, and paper. This relates to the mounting machine.

[Prior art]

2. Description of the Related Art When folding and holding shirts, underwear, socks, gloves, etc., or when holding multiple pieces or a pair of clothes, a holding tool called a clip is generally used.

This clamping tool may be integrally molded of synthetic resin or made of aluminum, and various shapes are manufactured depending on the material and thickness of the object to be clamped.

In the case of clamps made of synthetic resin, the tip of each clamp is opened manually and then clamped to the object to be clamped. For this reason, the shape of the tip of the clamp is designed to be easy to open by hand and to make it easy to clamp to the object, for example by making one end short and the other long.

However, since all the clamping work is done manually, the work efficiency is very low, and in addition to requiring a large number of workers to clamp a large amount of objects at once, there is also the safety problem of rough fingertips. and,
Because it is assumed to be done manually, one side of the clamping tool is long, making it longer or larger than necessary, and when clamping, it is necessary to check the installation direction, which is an inefficient and uneconomical problem. It was hot.

In addition, in the case of aluminum, the work is done by holding down both ends of the open clamping tool with your fingers, bending it, and then pinching each object one by one. There was a problem that the surface became rough and dirty.

By the way, the original shape of the clamping tool not only secures the object to be clamped, but also
It is determined by considering size, safety, economic efficiency, etc. Basically, it is small and has a beautiful appearance, and has an extremely simple shape without any unnecessary protrusions. Ideally, it should be

There has been a desire for a mounting machine that can efficiently and safely clamp such a simple and ideal shape.

On the other hand, there is a known mounting machine in which a metal clamp is loaded into the mounting machine and manually pushed out and clamped, but this mounting machine has ears shaped on both sides. A metal clamp having a protrusion is clamped along the guide by engaging the ears with flared guides provided on both sides inside the mounting machine and manually pushing it out linearly. The opening of the tool is opened to hold documents, etc. (Refer to Japanese Utility Model Publication No. 57-59346) Therefore, it is necessary to provide this clamping tool with ears for engaging with the guide, which is unfavorable in terms of appearance for clamping and displaying products such as clothing. There are problems with soft products such as scratches or the need to use more material than necessary, and the above-mentioned known attachment machines cannot be used for textile products such as clothing, leather products, etc.

[Purpose of invention]

The present invention was devised to solve the problems of the conventional method of attaching a clamp, and it not only makes the attachment of the clamp more efficient, but also has a simplified shape, easy molding of synthetic resin, and a beautiful appearance. Another object of the present invention is to provide a clamping tool attaching machine that can use clamping tools with high safety.

[Structure of the idea]

To achieve the above object, the clamp attachment machine according to the present invention has a clamping opening at the tip for gripping the object to be clamped, and a main body having a lever for driving a piston at the rear, and a roughly U-shaped clamp made of synthetic resin. The clamping tool mounting machine is provided with a tool loading section, and pushes the clamping tool in an expanded state to the clamping port by advancing a piston by operating the lever, the conveying path from the loading section to the clamping port being On one side of this conveyance path, there is a split rail portion extending in the longitudinal direction, and two expanding rails that extend forward from the end of the split rail portion and form the wall surface of the clamping port. an opening rail consisting of an opening rail, an escape section for allowing the clamping tool to escape from the opening rail near the end of the opening rail section, and a surface opposite the opening rail of the conveyance path; The present invention is characterized in that a pressing member is provided for elastically pressing the holding tool toward the opening rail.

In other words, an opening rail consisting of a split rail section and two expanding rail sections is formed on one side of the clamping tool conveyance path formed in the clamping tool mounting machine, and the clamping tool is opened on the opposing side wall surface of this opening rail. A pressing member for elastically pressing the rail side is provided, and an escape portion for allowing the clamping tool to escape is formed near the end of the open rail.

Therefore, the clamping tool pushed out from the loading section has its rear part (opposite to the opening) pushed by the piston, and its side parts elastically pressed by the pressing member, so that the clamping tool is pushed against the axial direction of the main body. Move forward diagonally. Therefore, the opening part moves forward by holding the opening rail part in its mouth, and further opens its mouth wider than the above-mentioned clamping opening by the expanding rail part, and eventually opens with its posture parallel to the axis direction of the main body by the escape part. It escapes from the rail and at the same time clamps the object held in the clamping opening at the tip of the main body.

The opening rail may be in the form of a thin plate that can be engaged with the opening of the clamping tool in front of the clamping opening.
The opening of the engaged clamp tool is widened toward the clamping opening at the distal end, and the clamping opening at the distal end is expanded into a bifurcated shape along the edge of the clamping opening. Ru.

Further, the width of the opening rail constituted by the split rail portion and the expanding rail portion may be such that the tip portion of the clamping tool can be engaged with it.

In addition, the escape part formed near the end of the opening rail includes a flat part formed from the tip of the main body to the tip of the opening rail at the same height as the protruding height of the opening rail from the side wall of the main body, and a flat part formed from this flat part to the gripping opening. It consists of an extending slope. This escape part guides the tip of the clamping tool, which is pushed forward by the piston, to a flat surface by the above-mentioned slope, and at the same time allows the clamping tool, which is oblique to the axial direction of the main body, to escape in parallel. .

The pressing member elastically biases the clamping tool against the opening rail side while the clamping tool is being pushed out from the rear so as not to separate from the opening rail, and the pressing member is a plate spring made of synthetic resin. Good, but
A coiled spring or the like may also be used.

is attached via a hinge 15.

On the other hand, the left frame body 20 includes a side wall 21, a clamping opening 4' which is symmetrical to the clamping opening 4 of the right frame body 2, a split rail part 23 for guiding the clamping tool 6, and an enlarged part extending from the split rail part 23. It consists of an open rail portion 25, a pressing spring 26 for pressing the clamping tool 6 toward the right frame 2, and a receiving surface 28 provided on the same surface as the receiving member 7.

A series of movements of the clamp holder 6 when the clamp holder 6 is loaded into the clamp holder attachment machine 1 configured as described above and clamps an object 30 will be described with reference to the drawings.

First, as shown in FIGS. 3 and 5, the clamping tool 6 inserted from inside the clamping tool holding case 5 is loaded sideways into the supply part 16 formed on the receiving member 7 and the receiving surface 28, and is inserted into the piston 12 from the rear. As a result, it is pushed forward (in the direction of arrow F).

As shown in FIGS. 1a, 4, and 6, the side portion 6d of the clamp 6 pushed forward is pressed by the pressing spring 26, and the clamp 6 is pushed in the direction of the side wall 3. At the same time, the tip portion 6a moves forward while slipping downward from the supply port 17 along the inclined portion 8a of the attitude control portion 8.

And the end portion 7a of the receiving member 7 shown in FIGS.
The clamping tool 6 has fallen off and is tilted to one side.
A rotational moment is exerted by the pressing force P of the pressing spring 26, and the sheet is released from the posture control section 8, and is sent into the conveying path 14 with its direction changed in the vertical direction as shown in FIG. 2a.

The clamping tool 6, which has changed its orientation in the vertical direction, is further pushed forward by the piston 12, and is then pushed forward by the pressing member 9 provided in front of the posture control section 8, as shown in FIGS. 3, 4, and 7. is pushed in the direction of the side wall 21. Then, as shown in FIGS. 2b and 3, the tip portions 6a and 6b
The opening 6c formed in the opening 6c sandwiches the split rail portion 23 diagonally from the rear.

In other words, the rear end 6e of the clamping tool 6 is in contact with the edge of the split rail 23, and the tip parts 6a and 6b are engaged with the split rail 23 or the expansion rail 25. It is designed to be pushed out diagonally to the target.

A Y-shaped expansion rail section 25 is extended at the end of the split rail section 23, and as shown in FIGS. 2b and 8, the opening 6c of the clamping tool 6
moves forward with the opening rail part 23 in its mouth, and opens larger than the clamping opening 6 by the expanding rail part 25.

Furthermore, when the clamping tool 6 is pushed out to the escape portion 25' at the end of the expanding rail section 25 shown in FIGS. 3 and 4, it is released from the pressing member 9 and expands parallel to the axial direction of the main body. At the same time as it escapes from the open rail portion 25, the object 30 held in the gripping openings 4, 4' is gripped.

Such a series of movements of the clamping tool 6 are controlled by the piston 1 by operating a manual lever (not shown) of the clamping tool mounting machine 1.
This is done almost instantaneously with an extremely small force by pushing the clamp holding case 5 forward.
The clamping tools 6 supplied one after another can be continuously pushed out.

In this embodiment, the clamping tools 6 are stacked above the clamping tool attaching machine 1, loaded horizontally in the supply section 16, and turned vertically when pushed out to the conveyance path 14. It is also possible to load the tool 6 from the side of the clamp attachment device 1 and press it against the split rail portion 23 with a pressing member or the like without changing the direction.

[Effect of idea]

As described above, the clamping tool attaching machine according to the present invention has a clamping port at the tip for holding the object to be clamped, and a main body having a lever for driving a piston at the rear, and a roughly U-shaped clamping tool made of synthetic resin. The clamping tool mounting machine is provided with a loading section, and pushes the clamping tool into the clamping port in an expanded state by advancing a piston by operating the lever, and a conveyance path from the loading section to the clamping port is formed. On one side of this conveyance path, there is a split rail section extending in the longitudinal direction, and two expanding rail sections that extend forward from the end of the split rail section and form the wall surface of the clamping port. Further, an escape portion for allowing the clamping tool that is engaged with the opening rail to escape is formed near the end of the opening rail portion, and further, an escape portion is formed on the opposite surface of the opening rail of the conveyance path. The present invention is characterized in that a pressing member is provided that elastically presses the clamping tool toward the opening rail.

Textile products such as shirts and underwear are delicate products, and the clamping tools used for them must not damage these delicate products. Therefore, the clamping tool used in this invention has a flat U-shape when viewed from the side, and is made of a narrow synthetic resin molded product, with guide parts such as ears for opening the mouth at the tip. It does not have a certain protrusion. There is a metal plate clip for documents that is similar to this clamping tool, but in the case of this clip, large ears are formed on both sides of the upper and lower openings, and these ears are used to carry the document through the attachment device. The opening is engaged with guide members made of Y-shaped metal plates provided on both sides of the path. However, since the clamping tool of the present invention does not have any protruding parts such as ears, such an opening mechanism cannot be used.

The clamping tool mounting machine according to the present invention advances the clamping tool in an oblique state with respect to the axis of the mounting machine by pressing the clamping tool against one wall surface of the conveyance path when pushing out the clamping tool, and the tip part is pressed against the wall surface of the conveying path. The clamping tool is engaged with an opening rail formed in the opening rail, and as the opening rail moves forward, the opening rail opens the upper and lower surfaces of the clamping opening that holds the textile product, etc., and the posture of the clamping tool is changed at the same time as the clamping tool escapes from this opening rail. The machine is aligned with the axis of the attachment machine to ensure accurate attachment to textile products, etc.

Therefore, since the clamping tool used in the present invention does not require an opening guide member consisting of a protrusion such as an ear at the tip, it is possible to reliably attach the clamping tool without damaging the textile product. can. In addition, the clamping tool is made of synthetic resin and has a narrow width with no protrusions at the mouth, so it does not require a large area for mold making, and there is no need to drill holes in complex-shaped cavities, so mass production is possible. suitable for Furthermore, since they are stable even in a stacked state, a large amount of them can be loaded into a mounting machine, which simplifies the mounting operation.
