Description

[Detailed Description of the Invention] Industrial Application °: The present invention mainly relates to a mount for packaging solid articles such as industrial parts in a series in a predetermined manner, and separating them into individual bags as needed. This article relates to a series of mounts with a hood and a method of manufacturing the same.

Background of the Invention: Equipment that is widely accepted and used in households and businesses, such as electronic equipment such as televisions, personal computers, audio equipment, and other machinery, has a tendency to deteriorate over a long period of time. Nine.

When shipped from the factory, they are adjusted so that they can be used without special care, are inspected, packaged and shipped, and are still functioning properly even after they are in the hands of users. In most cases where a failure occurs due to this reason, it is inspected and repaired by an expert engineer, and in order to repair these devices, the manufacturer of the equipment has to assemble various parts and manufacture separate parts. We are trying to supply it to experts.

Among these so-called repair parts, large parts are naturally packaged and supplied individually in packaging boxes, but small parts are handled in relatively large quantities, so
It is necessary to be able to handle this rationally. However, since Jin's extremely small parts have slightly different dimensions and are easy to replace, such parts should be packaged individually and labeled with the part number to prevent handling errors. management methods have been adopted.

Therefore, to enable effective product management of these small parts, we package them together.

Furthermore, considering the intended use, it is desirable to package each item individually. From this point of view, it is conceivable to use blister-type packaging or multiple bundles of synthetic resin film, and to pack individual items in T-shaped sachets (or multiple items of the same item if necessary). Moreover, if it is necessary to indicate the specific nature of the part, a label must be attached to each part, which increases packaging costs. As mentioned above, these parts are not purchased and used directly by the end user, so it is possible to use minimal and effective packaging in terms of handling (including product creation). It needs to be cheap.

For this reason, it is necessary to rationalize the packaging method for repair parts.

In addition to the above-mentioned purpose, for general products, it is necessary to provide decoration to the packaging of the product during the distribution stage, and to provide rigidity to the packaging and display of explanations of the contents, etc. Nine products have been put into practical use by forming a blister and attaching a film container to the product.

However, this type of packaging is used for relatively large items, and for small items, the manufacturing costs are high, so it is rare, and since it is often packed in 11 pieces, it seems convenient to handle. This is inconvenient because you have to align and cut them. Therefore, a rational packaging type is desired.

Purpose of the invention: The present invention was made in view of the above situation; The object of the present invention is to provide a continuous packaging body made by waving a resin film, removing the shape of a bag portion, and adhering the same, and a manufacturing method for easily obtaining such a continuous packaging body.

Structure of the Invention: To achieve the above object, the present invention has perforated holes at a predetermined pitch in a part of the edge, and prints or prints the required information on one side, and then prints the required information. On the other side, a paperboard of the required width made by laminating a thermoplastic resin layer is perforated by cutting out the edge of the feed hole 9 and cutting out the connecting part, and then the resin layer forming side of the paperboard is Thermoplastic resin film on top,
The permissible volume for receiving the packaged product is made into a bulging shape and welded along the perforation position of the connecting part and the perforation at the bottom position,
It is configured so that the products can be wrapped one bag at a time in succession.
It's in the future.

In addition, in the present invention, printing or a decorative layer is also formed on the resin layer forming side of the paperboard strip that can be continuously fed, and a film with decorative printing is used in addition to a transparent film as the resin film for forming the bag. However, it can also be used to add decorative qualities to the whole. In this case, it is effective to provide a partially transparent area so that the contents can be viewed in a transparent manner.

In the present invention, as a means of manufacturing such a continuous packaging bag, one side is printed in advance, the other side is coated with thermoplastic resin, and the edges are provided with perforations T at a predetermined pitch.
- At the same time as perforations for green cutting in the feed direction and perforations for connecting cutting 9 at a required pitch perpendicular to this, a paperboard of an appropriate thickness and continuous width is used as a mount, and the resin coating is applied. The resin film is supplied intermittently at a required pitch with the side facing upward, and a resin film having a width narrower than the width of the continuous mount is superimposed and supplied on the upper surface where the continuous mount moves while keeping the continuous mount in a tensioned state for a certain period, On the advancing side, press and temporarily attach the film exactly at the perforation for continuous cutting of the paperboard, and then, while the mount moves one pitch, the required amount of film is over-supplied with the feeding piece of the over-supplying means, so that it rises in a wave shape. , when the feeding piece advances to the farthest point, the film is suppressed and tacked onto the backing paper in the process.
In the next step, the temporary attachment is heated and pressed again to attach the final attachment, and then one side is bottom-sealed, and the continuous paperboard is cut out and a bag made of film is sequentially attached to each section. It forms a bulge.

In the present invention, during the process of feeding out the continuous mount, a printer prints necessary information in a display column provided in advance on the print surface so that the packaged items can be identified.

When such a printer-based printing means is employed, the continuous packaging bag sent out after the bag making process can be directly transferred to the article loading process iC, and the desired articles can be loaded with the bag opening facing upward.

When manufacturing continuous packaging bags, each operating part should be linked, and the amount of paperboard fed should be the same as the length of one bag (in the feeding direction).
One bag at a time is transferred according to W'c.

Examples: Hereinafter, the present invention will be described in detail with reference to the drawings with reference to examples.

FIGS. 1 to 3 show a continuous packaging bag (n) of the present invention, which includes a mount I mainly composed of a continuous paperboard sheet η of an appropriate thickness, a thermoplastic resin film I41 It consists of a bag (3) part formed by measuring and forming a bulge and heat-sealing both sides and the bottom part (both completed as a packaging bag - based on the case).
+61 (?) It is connected so that it can be cut by K.

Then, we used a mount ttl ti, a paperboard circle called so-called white 9 board, with a relatively light basis weight (thin thickness), and formed it into a strip of the required width, and then white-laminated the outer surface @ □□□ corresponding to the product to be packaged, a column for entering the product name, the name of the handling company, etc. A known thermal adhesive layer is coated with a plastic resin.

This mount 11 has feed holes (6) at a predetermined pitch on both edges.
There are 9 perforated edge cutting lines +61 in parallel to the inner position of the perforated portion of the feed hole flil.
+61 is engraved, and the cutting line of both R parts of the makuko is +61 +
61, perforations are made as connecting perforation lines (7) for cutting off each bag at required intervals corresponding to the packaged products according to the printing on the outer surface (2), and the edge perforation line 161
It is a chopping throw by staying at the position where the ft31 crosses.

The synthetic resin film bag (3) that is pasted onto the mount (2) is attached to the connecting perforation line (as shown in the figure) and one edge perforation line (6) (on the opposite side). Heat-seal it with the inside position of the mount 12) and form a bulge on the mount 12). The volume of the bag (3) made of this resin film can be set depending on the amount of expansion of the film.

According to the packaging bag Ill VC constructed in this way, the bag (3) portion is formed on one side of the mount, and the bag (3) portion for accommodating the article can be set by forming a bulge on the film. Because of this, unlike conventional blister-shaped containers that are vacuum-formed, it has the economical effect of being able to be manufactured to any size as needed. Then, when unpackaged, attach a feed hole: 6) and set it to state 2, supply the manufactured product on a reel, use this feed hole +51 f: to put it into a packaging machine, and manually or automatically operate each packaging bag. g1
3) By pushing the packaged product into the box and heat-sealing it at the opening 131', it is convenient to carry out the packaging operation continuously. Then, as for the delivery method after packaging, cut out the edge 181 (81) with the feed hole (5) along the cutting line tel +81 of the 2nd class part and adjust the number of packages appropriately, for example, 6
Cut pieces or 10 pieces into one unit, and distribute the pieces by putting them into a multi-color device 1311C as appropriate.

By using this packaging type, for example, when packaging items such as electronic parts and parts for electrical equipment that are used by specialized engineers for repairing equipment, the packaging can be printed on the outside screen of the mount (2). By writing the "product number", "parts code", etc. in the space, it is possible to create packaging that can be sorted and used without making any mistakes. can be handled without damaging parts. If the packaged product (A) is cut into one bag, it will look like the one shown in Figure 4.

Furthermore, when packaging small quantities of 10 items one by one, it is possible to divide the items into the appropriate number of packages at the gJ line (7) and manually package them, making it easier to use the packaging machine. All you need to do is have something that can do heat sealing all at once.

In this case as well, the series of mounts allows the plurality of packaging bags (11) to maintain stable postures and facilitate packaging.

Naturally, since a simple packaging format can be used, it can be useful for reducing packaging costs.

In addition to the above, the mount can be colored on the inside surface (using a double-sided white board), laminated with a foil layer, coated with resin on the surface, and coated with resin to form the bag. If the film is colored and printed leaving a transparent part locally and a T-type film is used, it can be easily packaged in a highly decorative state, and in this way it can also be used for general distribution products.

As shown in Figs. 5 to 7, the method for obtaining a packaging bag as described above is as shown in Figs.
sl Is) 17] of the required width are fed by being fed out from a reel that is unwound. Feeding pin gear 111! ill! The pins are engaged with the feed holes (5) on both edges (t) and moved intermittently to maintain tension at all times. The width of the mount placed above the mount (the machine base: 10) that is fed out in this state is approximately equal to or slightly narrower than the width of the mount cutout line + 6) + 6j on both sides of the mount. The synthetic resin film (4) wound on a reel is fed out, guided from near the upper side of the feeding side pin gear (river position) to guide row 2 (+) so that it is superimposed on the mount I21, and set. For the mount 12), the film (4) is fed forward so as to overflow the top surface and scoop up the film (4), and when it retreats, it rises slightly and moves away from the film (4) surface (as shown by arrow A). The film (4) is forwarded by an overloading means having a one-sided movement.
At the front of the feeding piece (υ) at the most forward position, there is a narrow heating plate on the bottom surface of the sealing piece ab, which is perpendicular to the direction of film travel and interlocks with the continuous feeding of the mount t. A primary sealing mechanism α4 is disposed to move up and down by moving the film (4), and before the film (4) is fed, the sealing piece (II is lowered and the mount 12) of the primary sealing mechanism 01 is cut out, which is provided with an IC. line (7)
Then, the film 14) is temporarily welded to the upper surface of the mount 12).

While the seal piece (after II rises, the mount!!) is fed the length of its length, the film (4) is over-supplied by the over-feeding means, and the film (4) is placed on the mount I. Bulge (a
) and move. At this time, the oversupply amount of film (4),
That is, if the amount of one stroke of the feed piece @υ is lengthened, the amount of bulge of the film forming the bag will increase9, and conversely, if the amount of one stroke of the feed piece @υ is shortened, the amount of bulge of the film will become smaller. In this way, as the feeding piece @gen of the film wrapping means moves forward together with the mount I2) in one stroke, the next cutting and collecting line (7) position is near the primary sealing position (a) K, so the feeding With the film (4) pressed against the upper surface of the mount I2 by the film (4), lower the seal piece (lf9) of the primary sealing mechanism (4) and bulge (a). Temporarily weld the ° film to the top surface. In this state, as shown in Figure 6, the film +41 is welded to the back and front of each bag in a narrow width on the mount (2) in a direction that intersects the direction of travel. Therefore, if this continues, the film ζ4) will be attached to the mount in a wavy manner.

While repeating such operations sequentially and progressing intermittently,
The nine parts temporarily welded in the previous step are again provided with a sealing piece H in the same manner, and the film is completely welded onto the mount by the secondary sealing mechanism. Then this secondary seal mechanism 0
・At a position 7-slightly away from the placement part, one side edge of the film in the bulging state +C is sealed along one side of the edge cut line (6) of the mount (2) parallel to the moving direction by the bottom seal mechanism. - The seal piece 5 (same as the above seal piece) presses and welds the mount +2+ when it is in the stop group. At this time, one end of the bulging film is squeezed and heat-sealed in the T state, and although wrinkles occur, the film is melt-sealed and forms the bottom of the bag, so there is no structural problem.

While progressing in this way, the film, which was shaped into a wave shape and welded together with the mount, was folded twice on both sides of the completed bag and welded to A1, and then attached to the bottom. The nine pieces sent out from the top of the machine are wound up at a separate location and sent to the next process. In addition, in some cases, the products sent out after the bag-making process are successively moved to a separate position or an adjacent position, and the items to be packaged are put inside through the gates of the six bags, and the openings are melt-sealed. In this way, it is also possible to perform a series of operations from bag making to packaging.

As described above, according to the method of the present invention, the mount is moved in accordance with the set conditions by meshing with the feed hole provided at the edge of the mount and the driving and guiding pin gear, and the bag portion attached to the mount is overloaded. By moving the film by a length longer than the amount of movement of the mount using the offering means, and by fixing the front and back of the movement to the mount with seal pieces, the amount of expansion of the film can be arbitrarily determined and the amount of the film bulging can be arbitrarily determined. The capacity of the (bag) can be set, and a continuous bag can be obtained in which the bulging bag portion is adhered to the mount without the need for a mold. If the length of the bag used as a bag is short) or the backing paper is relatively thick, and it is difficult for the paper to twist during movement, it is also possible to feed the paper by providing a K-feeding hole only on one edge. lie In this case, the width of the film may be set to 9 dimensions in consideration of sealing.

Effects of the invention: According to the present invention, it is possible to form a packaged object storage section on one side of the mount without the need for a mold through an extremely simple manufacturing process, and the mount and the film attached to one side of the mount can be easily formed. By optionally using it, it is possible to obtain a so-called simple packaging type continuous package or a product package with a mount, reducing packaging costs and making it suitable for managing parts, etc., or a package convenient for distribution. It is now possible to provide it.
