Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention provides a mounting piece in which a head, a horizontal bar, and a central part thereof are connected by a filament part to form an H-shape. and the horizontal bar parts are arranged in close contact with each other, for example, the horizontal bar parts are arranged in a single plate shape (sheet shape), and the head and the central part of the horizontal bar part are connected so as to be cuttable. This is a super dense assembly of mounting parts.

The attachment piece assembly according to the present invention has no unnecessary members when attaching price tags, etc., such as connecting rods, and furthermore, the individual attachment pieces are not connected to the connecting rod via the connecting portion. Nevertheless, it relates to something that can stand on its own and that will not be disarranged when loaded into a mounting device.

[Prior art]

A member called a mounting piece or tag pin is used to attach a price tag or the like to a product or to group two or more products together.

As shown in FIG. 6, this mounting piece p consists of a head 1, a horizontal bar 2 facing the head 1 at a distance, and a filament 3 connecting these parts.
are integrally molded as a mounting piece assembly P from a thermoplastic synthetic resin such as nylon or polypropylene in a state where they are planted in a comb shape on the connecting rod 5 via the connecting portion 4.

As shown in FIG. 7, this assembly P of attachment pieces p is loaded into the guide groove 10 of the attachment device T, and the hollow needle 11 is inserted into the hole of the tag 12. A piston (not shown) is actuated by inserting it into a product such as the above, and by squeezing the lever 14 that moves in and out of the groove in front of the grip part 13 of the mounting device T, one mounting piece is removed from the assembly P. The tag 12 can be attached to a product by separating the cross bar 2, passing the horizontal bar 2 through the hollow needle 11, and projecting it from the back of the product.

By the way, in the generally used mounting part assembly P, the diameter of the horizontal bar part 2 and the thickness of the head part 1 are approximately 1 mm, taking into consideration problems in mold production and the thickness of the hollow needle 11. The distance [l] between the horizontal bar portions 2 and the connecting rods 5 is set at approximately 2 mm. In this relationship, usually 25 to 50 attachment pieces P are planted for one connecting rod 5 to form an attachment piece assembly P.

The connecting rod 5 of this attachment piece assembly P corresponds to a runner bar during molding and is also a support rod, but is set to a size that allows it to be relatively easily bent. Therefore, when using a long attachment piece assembly P with a long connecting rod 5, it is easy to bend and wobble as shown in FIG. 7, which poses a problem in handling. Not possible, many mounting pieces p
could not be planted on one connecting rod 5. In other words, it was essentially impossible to assemble a large number of attachment pieces into one assembly.

Another problem is that when the mounting piece p is driven in, the connecting rod 5 protrudes below the mounting device T, but the connecting portion 4 remains in a "comb-like" shape on the connecting rod 5, and the horizontal bar of the connecting portion 4 The base of part 2 is cut with a knife built into the mounting device T, and the tip has a sharp shape, so it often gets caught on the product and damages the product, so be careful when driving. There was a need to anticipate this.

Another problem is that the connecting rod 5 and the connecting part 4 are essentially unnecessary when attaching the tag 12 to the product, and moreover, they account for approximately 20 to 35% of the total weight of the attachment piece assembly P. %, which was a waste of resin and caused an increase in material costs, but with conventional mounting piece assemblies these parts cannot be omitted. It was.

As mentioned above, the attachment piece p is attached to the connecting rod 5, which is completely unnecessary for tagging work, through the connecting part 4.
Sparse planting at mm intervals requires relatively wide intervals between the cavities of the attachment piece p formed in the mold. Furthermore, since the connecting rod 5 functions as a runner bar when injecting resin into the cavity, it is advantageous in designing and manufacturing the mold, and it is also convenient in handling the mounting piece assembly.

However, arranging the mounting pieces p sparsely at intervals of 2 mm means that the connecting rod 5 is a member that exclusively supports the mounting pieces.In other words, the connecting rod 5 should not be too thin. This increases flexibility and makes handling difficult, making it difficult to change to a thinner one.

Furthermore, when the attachment pieces p are sparsely planted on the connecting rod 5 as described above, there is a problem in that these pieces tend to swing individually.

In addition, as mentioned above, in the case of an assembly in which mounting pieces are installed sparsely on a single connecting rod, a large number of items are stored in a box and transported, and when used, the assembly is handled by hand. After taking them out and using them, the leftovers are put back into the box. In this case, if there is a space between the heads of the mounting pieces that corresponds to the thickness of the mounting pieces, the heads and horizontal bars of other assemblies will fit between the heads and become entangled with each other. It becomes difficult to take out.

As mentioned above, the conventional mounting part collection section has the following objectives: arranging a large number of parts together, omitting unnecessary members, making the assembly stand on its own on the mounting device, streamlining the molding process, and making the mounting process more efficient. It was as if little consideration had been given to responding to various demands such as eliminating tangles of parts.

On the other hand, Japanese Patent Publication No. 52-20240 proposes a mounting piece assembly in which the center portions of the sides of the heads are connected by a disconnectable connecting member in order to align the heads.

However, in this mounting piece assembly, the mounting pieces are installed on the connecting rod 8 via the connecting part 10, and when this mounting piece is used, both the above-mentioned members 8 and 10 are originally It's unnecessary, and that much material is needed.

Furthermore, during the attachment operation of the attachment piece, the tip of the connection part 10 that is cut by a knife built into the attachment device and remains in the shape of a comb on the connection rod 8 is sharp, which can damage delicate products. There is a problem.

In addition, in a mounting piece assembly with this structure, if the mounting pitches of the mounting pieces are made to be very close together (or in close contact), the thickness of the wall forming the cavity of the mold will become extremely thin, and the pressure resistance will be almost completely reduced. You end up losing and not really producing from a relationship like this.

[Purpose of the invention]

The present invention has been achieved in order to solve the various problems of the conventional mounting piece assembly, and its objectives are: (1) to be assembled in a compact and ultra-dense state; To provide a mounting piece assembly with excellent handling properties.

(2) In conventional mounting piece assemblies, the connecting rod, which serves the function of assembling the mounting pieces and the function of a runner bar that serves as a resin injection path, is completely omitted, resulting in unnecessary parts. To provide a new mounting piece assembly.

(3) To provide an assembly of mounting parts that does not cause damage to products, etc. since the connecting rod is omitted.

(4) To provide an assembly of mounting parts that assembles into a mass by itself, is self-supporting, and has excellent handling properties such as packaging, transportation, and mounting operations in mounting equipment.

(5) To provide a mounting part assembly that is extremely dense and does not allow other mounting part assemblies to get between the heads and cause tangles.

(6) As a result of the extremely densely packed cavities, the molds have become smaller, and it is now possible to easily control the temperature of the molds, and to provide an assembly of mounting parts that can effectively inject resin. be.

[Summary of the invention]

The present invention for achieving the above object is comprised of the following requirements.

A: The head and the horizontal bar are arranged in parallel with each other at intervals, and the mounting piece is formed by connecting the central parts of both members in an H shape with a filament part. It is a block-like aggregate made of synthetic resin, with parts arranged side by side in a super dense arrangement.

B: The central part where the heads face each other and the central part where the horizontal bar parts face each other are connected, and the connecting part of the horizontal bar part can be cut by a mounting operation using a mounting device. The connection part of the head is strong enough to be manually severed during installation.

The attachment piece assembly according to the present invention completely omits the connecting rod and the connecting portion, which are unnecessary members for attaching a price tag or the like.

As a means of achieving this, the head part and the horizontal bar parts are brought as close as possible to each other, in other words, the mounting pieces are substantially stacked in a super-dense manner, and the structure is made to stand on its own by utilizing the density effect. It is something.

Super-densification means that the cavities are arranged at intervals that are permissible for manufacturing purposes, taking into account the strength of the mold, and the mold is molded using this mold, and the aggregate resembles the shape of a stapler. It is integrated like this.

Adjacent heads and horizontal bars are connected at least in their centers, but the strength of the connection must be such that they cannot be easily separated during packaging, transportation, and installation work. do.

The connection between the horizontal bars is broken only by the attachment operation using the attachment device, and the connection between the heads is torn off manually when the attachment pieces are attached. Specifically, even if the locking piece assembly is handled during packaging, transportation, and installation operations,
At that stage, they are connected to such an extent that they cannot be separated, and they are separated when mechanical force is applied to the connection between the horizontal bars by the attachment device, and the connection between the heads is connected by hand during the installation operation. It is separated by operation.

From the above point of view, the strength of the connection between the heads is equal to or preferably weaker than the strength of the connection between the horizontal bars. That is, since the horizontal bar advances through the hollow needle of the attachment device, it is possible to perform a cutting action during that time, and it also needs to have the function of holding the assembly of attachment pieces integrally in the form of a block. However, the head cannot be given such a special cutting action, and can therefore be easily cut by the movement of the hand when attaching the attachment piece.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a front view of a mounting piece assembly P according to an embodiment of the present invention, FIG. 2 is an A-A missing view in FIG. 1, and FIG. 3 is a B-B missing view in FIG. It is.

The mounting part assembly P according to the present invention includes a mounting part p
It is characterized by the fact that the head, filament, and horizontal bar are arranged in a sheet-like manner as close together as possible, forming an H-shaped block as a whole, and arranged so that they can be separated.

As shown in FIG. 2, both side surfaces of the head 1 are formed into inclined surfaces and provided with a bulging portion 1a, and connecting portions 1b at the tips of the bulging portions 1a are connected to each other. Therefore, the heads 1 are formed into a substantially diamond shape in plan view, and a "triangular or wedge-shaped" gap 6 is formed between the two heads 1. Incidentally, this gap 6 forms a wall in a cavity formed in the mold, thereby making it possible to form a wall having sufficient thickness and strength.

Furthermore, as shown in FIG. 3, the horizontal bar portion 2 also has a substantially rhombic shape in plan view, with the width being the widest at the center and decreasing toward both ends. A triangular or wedge-shaped gap 6 is formed between the two horizontal bars 2 in plan view. As can be seen from FIGS. 1 and 3, this horizontal bar part 2 is like a cylindrical body whose flesh on both sides is gradually shaved off more and more toward the tip, and the cross section of the central part is circular. However, it is gradually formed into an elliptical shape as it approaches the end face, and a connecting portion 7 is formed in the center of the circular cross section.

As is clear from FIG. 1, in the mounting piece assembly P according to the present invention, both the connecting portion 4 and the connecting rod 5 are omitted, and furthermore, the head 1 and the horizontal bar 2 are located at their respective central portions. are connected by the connecting portions 1b or 7, and the connecting portions between the heads can be cut manually during operation of the mounting device T, and the connecting portions between the connecting rods can be cut by hand during the driving operation of the mounting device T. It is characterized by the fact that it is connected with the strength of

Since the connecting portion 7 formed on the horizontal bar portion 2 can be separated when being ejected from the mounting device T, the adhesive strength may be relatively high, but the connecting portion 1b between the heads 1 can be separated during the mounting operation. Insert the mounting device T into the tag 12.
The strength is such that it can be torn off manually without pulling the thread when separating from the product to which it is attached.

In FIGS. 4 and 5, both the head 1A and the horizontal bar 2 are formed in a cylindrical shape, and as shown in FIG. As described above, they are connected so as to be cuttable by the formed connecting portion 1b or connecting portion 7.

For driving the mounting piece assembly P according to the present invention, for example, an improved version of the mounting device of the invention described in Japanese Patent Publication No. 59-29489 can be used.

Specifically, the attachment device proposed in the above-mentioned publication has the feed pawl act on the “connecting portion 4,” but in the attachment piece assembly P according to the present invention, this connecting portion and Since the connecting rod is omitted, the feed pawl is configured to act directly on the "horizontal bar portion 2."

Furthermore, the following mounting devices have been developed specifically for driving this mounting piece assembly P and its further improved version.

(1) Japanese Patent Application No. 1983-71729 (Japanese Patent Application No. 1983-217071)
"Locking piece attachment method and device" (filing date: Showa
(April 12, 1959) (2) Patent Application No. 146745 (Sho 59-146745) (Patent Application No. 33923 Sho 61)
"Latching piece attachment device" (filing date: July 17, 1982)
JP) The devices according to the above two inventions are significantly different from the conventional concept, and the structure of the constituent members is simplified, easy to assemble, and requires almost no adjustment.

Also, the structure of the former is extremely simplified,
The design is also excellent. In the latter structure, the feeding device can be exchanged in a cassette type, so that all kinds of attachment piece assemblies can be filled.

[Effects of the present invention]

The present invention is configured as described above, and can produce the following effects.

(a) The mounting pieces p are extremely compact because they are arranged in a highly dense manner with no gaps between them. Therefore, in the case of the same number of attachment pieces as the conventional product shown in FIG. 6, the length is about half. In other words, if the length is the same as the conventional product, it contains about twice as many pieces, and the number of times it has to be loaded into the mounting device is halved.
Installation work can be performed efficiently over a long period of time.

(b) The H-shaped mounting piece has a head and a horizontal bar arranged side by side, and the central part of the horizontal bar is connected to such an extent that it is cut during movement during the driving operation inside the mounting device. However, the central part of the head is connected so as to be torn apart by a manual operation accompanying the attachment operation using the attachment device, and is formed into a single block as a whole.

Therefore, it is compact and well-organized, and does not become tangled during each process of packaging, transportation, and installation. Particularly, during the mounting operation, a handful of the mounting piece assembly is taken out of the box, loaded into the mounting device, and used, and the rest are casually thrown into the box.

In this case, the heads of other attachment pieces will not enter between the heads, and therefore the assembly will not be cut or entangled.

(c) Since the attachment piece assembly according to the present invention omits the connecting portion and connecting rod of the conventional one, when in use, the connecting rod with the connecting portion protruding like a ladder remains behind the attachment device. Nothing stands out more.

In conventional assemblies, items such as clothing were caught on the connecting rod itself and the remaining portion of the connecting portion, which was cut with a knife and protruded from the connecting rod with a sharp tip, causing damage. However, in the present invention, this can be completely prevented.

(d) Compared to conventional mounting piece assemblies, connecting parts and connecting rods are omitted, so there are no unnecessary parts. Therefore, the cost of materials for forming the connecting rod and the connecting portion can be reduced, and the attachment piece assembly can be provided at low cost.

(e) The attachment piece assembly according to the present invention is configured in a super dense state so that the head of another assembly does not enter the head, and the unnecessary parts are omitted as much as possible. Because it has the ultimate structure with no heat, it is extremely compact, which means that the mold is smaller and cheaper, and it is easier to control the temperature when heating the mold, which increases the product quality. The quality of can be stabilized.
