Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board pack packaging machine, a method for manufacturing the same, and a board pack.
More specifically, the entire process is fitted into the mold by supplying paper blanks to the mold with a board / pack for storing various electrical goods such as dry batteries and other small electrical products and other daily necessities. , A packaging method, a packaging method, and an obtained board / pack that are automatically packaged. It is characterized in that high-precision processing is possible, and that the entire packaging material can be recycled and used, and that there is no risk of producing components that have an adverse effect on the environment when burned.

[0002]

2. Description of the Related Art Conventionally, blisters have been used for wrapping various articles such as small electric products (electric small articles) such as dry batteries and other daily necessities. In general, dry batteries and the like are arranged on a board made of paperboard and made of transparent plastic.・ The method of covering with film and sealing is widely used. Here, the cover made of a transparent sheet has a great effect on inviting customers to purchase since the packaged contents are directly visible at the time of display.
Therefore, transparent plastic sheets included in the packaging of these articles have been considered an indispensable packaging material.

Although this is a conventional packaging method suitable for the needs of the market, even if the paperboard is beaten in water when recycled, the plastic sheet is not beaten, and it is not easy to separate and remove it. There is no recycling use. On the other hand, in the case of incineration, components that may have an adverse effect on the environment may be generated, and many problems have been pointed out, such as a request for resource reuse due to a dead end in waste treatment.

In addition, hot melt adhesives have been mainly used as adhesives for paperboard in the blister molding process. This is because the bonding time is short and the productivity is high. However, in order to recycle the paperboard after using the blister, it is necessary to beat it in water, but the paperboard containing the hot melt adhesive cannot be reused because it is difficult to beat.

[0005] To produce a conventional paperboard blister, blanks obtained by punching paperboard are pressed into a mold and formed. After the blanks are removed from the mold, application of adhesive, folding, and pressure bonding are mostly performed. It was done by hand. For this reason, it is difficult for the blanks to be folded back to align the left and right ends together by hand, so that it is difficult to make the blanks exactly match, and it is inevitable that some clearance remains.

Also, since the work of fixing the adhesive after the contents are stored is performed manually with the blister removed from the mold, there is some variation in the angle of the corner of the bent contents storage part. When a large number of blisters were displayed on a flat surface, it was difficult to obtain a completely aligned state.

[0007]

In view of these problems, from the viewpoints of environment and resource reuse, all recyclable materials, including adhesives, were selected as packaging materials for storing these contents. In addition, even if burned, there is no risk of producing components that have an adverse effect on the environment. In addition, all processes are automatically performed and high-precision processing is possible. In addition, labor-saving board pack packaging machines and board packs An object of the present invention is to provide a manufacturing method and a board pack according to the manufacturing method.

[0008]

Means for Solving the Problems The present inventors have studied a method of making the entire amount of packaging material used for a board pack recyclable, and provided a window in the paperboard board pack so that the contents can be seen. Focusing on the point that the same effect as that of the plastic sheet can be obtained, the conventional plastic sheet and paperboard combination method has been abolished, and the structure has been changed to a single paperboard sheet which is easy to reuse. Furthermore, it has been found that by using a vinyl acetate-based polymer emulsion containing a water-soluble polymer as an adhesive for board / pack molding, a paperboard containing a solidified adhesive can be easily beaten in water.

Furthermore, if an adhesive containing no compound containing chlorine and nitrogen atoms is used in a vinyl acetate-based polymer emulsion containing a water-soluble polymer, it can be recycled, and even when burned, environmental hormones such as dioxin, Alternatively, there is no risk of producing nitrogen oxides. In addition, by configuring the blanks to move automatically with the blanks fitted in the mold and performing all processing automatically, the precision of the dimensions and shape of molded products is higher than that of conventional products. The present inventors have obtained the knowledge that the production of packs becomes possible, and reached the present invention.

That is, a blanks feeder 2 which is capable of loading a large number of blanks made of a single sheet by punching a paperboard into an arbitrary shape for packaging the contents, and a large number of gold for processing and molding the blanks.

The present invention also includes a board pack manufacturing method, which comprises a step of bonding and solidifying by pressure bonding, and a step of removing the board pack from the mold 10 after the board pack is adhesively solidified. I have.

[0012] Here, after the blanks are supplied to the mold, until the molded board pack is taken out from the mold.
Also included is a method for manufacturing a board / pack that is intermittently conveyed in a mold and processing operations other than a part of the adhesive application step and the board / pack molding step are performed during the stop time. I have.

Further, a board pack obtained by the above-mentioned manufacturing method and having a bottom portion capable of standing upright in a plane, a board pack having at least one window at a position where contents contained in the pack can be seen from the outside, or The present invention also includes a board pack in which the contents contained in the pack are batteries or cylindrical batteries.

[0014] Alternatively, the adhesive used in forming the pack is a vinyl polymer emulsion containing no water-soluble polymer and containing a compound containing chlorine or nitrogen atoms, and can be beaten in water after solidification. Is included in the present invention.

Here, the blanks refer to a material for molding a sheet-like packaging container made of a single sheet of paperboard. In addition, a board pack is a type of packaging container that has a swelling part on the backing and can store the contents in that part,
This is a pack having a structure similar to that of a conventional blister, but hereinafter referred to as a board pack because of the addition of new features according to the present invention. Next, the present invention will be described in detail.

As described above, the board pack of the present invention has a shape in which a space for accommodating contents is provided in a part of a board made of one piece of paperboard. It has a structure in which stored items are visible from the outside. Board packs are produced by forming and processing blanks, which are used to form packaging containers and blanks, from which a paperboard has been punched by a packaging machine. The packaging machine comprises a blanks feeder 2, a conveyor 3, a blanks folding machine 4, an adhesive applicator 5, a contents inserting machine 6, a board / pack molding machine 7, and an adhesive crimping machine 8.

The blanks feeder 2 is loaded with a large number of paper blanks, each of which is made of a single sheet of cardboard. A wide range of types of paper can be used as long as the paperboard can be beaten underwater easily and can be recycled.However, coated white balls, which have a high percentage of used paper and can be recycled only from used paper, are made of blanks. Suitable for material. All blanks are made of paper only and do not include plastic sheets. This is so that all the used paper can be recycled as paperboard after using the board pack. This is because if a plastic sheet is contained, it is difficult to separate and remove it in a beating process in water, which is an obstacle to recycling the paper.

Further, in the present invention, the whole amount can be regenerated and recycled for use as an adhesive for board / pack molding by using an emulsion composed of only a component that can easily beat used paper used in water. If it cannot be reused, it will be incinerated as garbage or waste, and the purpose of resource saving cannot be achieved. It is also possible to use blanks in which holes serving as windows for making the contents packaged in a pack in advance visible from the outside are punched out.

Conveyor 3 has two chain wheels
The conveyor 3 is provided so as to circulate between the wheels 19, 19 'so that the surface of the conveyor 3 is horizontal when traveling between the wheels. A large number of molds 10 are provided on the outer surface of the conveyor 3 at regular intervals. The conveyor 3 moves intermittently, and the above-described processing is performed except for a part of an adhesive application operation and a folding operation at the time of board / pack molding. The operation is performed during the conveyor downtime.

The blanks are suckers for sucking one by one.
It is fed to the mold by an arm having 18 and transferred to the blanks folder 4. The blanks folding machine includes a press machine 11 and a folding machine 12, and the blanks 9 are pressed against the mold 10 by the press machine 11 to be pressed and depressed to form a content storage space. The blanks intermittently move while being fitted into the mold 10 and are turned by the folding machine 12 into a press machine.
The rising part of the blanks generated in step 11 is folded. At that time, the sheet is once folded deeply so as to be maintained in a predetermined shape even after the external force is removed. This is a board
This is an important operation for increasing the uniformity of the molded form of the pack, and is one of the important requirements of the present invention. If necessary, the further folded portion can be held in a predetermined shape by a holder until the upper half 24 of the blank is folded and crimped.

While the folded blanks are held in a predetermined shape, the conveyor 3 transfers the blanks to an adhesive applicator 5 where the adhesive is applied to predetermined portions. The adhesive applied here must have such a property that it can be beaten in water together with the paperboard even after drying. This is because the entire molding material of the board pack is recycled into paper and reused. For this reason, the adhesive must not contain a compound containing chlorine or nitrogen atoms, and must be a vinyl polymer emulsion containing a water-soluble polymer as a main component. Is more preferable from the influence on the environment. Furthermore, when the waste material is incinerated after the packaging material is reused several times, there is no possibility that a component having an adverse effect on the environment, such as nitrogen oxides, will be generated since the compound containing chlorine and nitrogen atoms is not contained.

Further, it is more preferable to increase the content of the water-soluble polymer contained in the emulsion in order to easily beat the board pack containing the solidified adhesive in water. At present, when a packaging container is produced by bonding paperboard, a hot melt adhesive is often used as an adhesive. This is because the solidification time after bonding is short and economical.
However, the solidified hot melt adhesive is difficult to beat and hinders the recycling of paperboard, and therefore cannot be used in the present invention for the purpose of recycling packaging materials.

The application mechanism of the adhesive applicator 5 is not particularly limited, but a system having a transfer mechanism is preferred in order to uniformly apply the aqueous dispersion emulsion. This is a method in which an emulsion-type adhesive is applied to the surface of a roller to a uniform thickness with a doctor blade, and then applied to blanks via a roller that transfers the adhesive only to the applied portion. The blanks to which the adhesive has been applied are transferred to the content insertion machine 6, where the contents are inserted into the storage space.

When the emulsion adhesive is pressed,
After the application, it is preferable to evaporate water in the dispersion medium to a certain extent to increase the adhesive strength and then to solidify by pressure bonding. That time is usually referred to as open time. In the present invention as well, the blanks are transferred to the molding machine 7 after the adhesive is applied and the contents are inserted and the conveyor is stopped without any processing. If necessary, hot air may be blown to the adhesive-coated surface during this open time to promote drying.

The upper half of the blanks to which the adhesive has been applied during this transfer (the part on the back side of the board pack) is
A board pack including a content storage portion is formed by folding over and overlapping the content storage space fitted in the mold 10. The contents storage section is the mold at the next conveyor stop time.
In the state where it is fixed at 10, when both ends of the folded blanks are pressed from the outside to match the ends, the ends on both sides exactly match and the contents storage part is further included The board pack is formed into the correct shape. This is one of the important requirements of the present invention.

The blanks are transferred to the board / pack molding machine 7, and about half of the side on which the adhesive is applied is folded back over the contents storage space fitted in the mold 10,
A board pack including the contents storage is formed. At this time, since the storage portion is fixed by the mold, if both ends are folded back and pressed from the outside to match the ends, the ends on both sides exactly match and further include the storage portion. A board pack with high dimensional and shape accuracy is formed. It was stated that this is one of the important requirements of the present invention, because it is difficult to exactly match the ends on both sides due to the procedure of manually molding the board pack,
Therefore, a slight variation appears in the shape of the pack.

The adhesive crimping machine 8 includes at least one crimping machine, and the adhesive is solidified by a heating and crimping operation to complete a board pack. A configuration in which blanks are intermittently moved while being fitted into the mold 10 from the time the blanks are supplied to the mold 10 until the board pack is obtained, and the processing operation is performed within the stop time. Therefore, their required times are set the same. For this reason, in order to dry and solidify the emulsion adhesive containing a large amount of water as a dispersion medium, one-stage pressing time may be insufficient depending on the season. To compensate for this, it is preferable to provide a two-stage or three-stage pressure bonding process.

All the processing operations are automatically performed until the molding of the board pack is completed. When the conveyor 3 is turned upside down and the conveyor 3 is turned over, the board pack that has been produced falls out of the mold 10 and falls on the carry-out conveyor, or is forcibly pushed out of the mold and falls, and is dropped by the carry-out conveyor. Will be carried out.

The structure of a conventional blister pack is packaged using a combination of paperboard and a transparent plastic film so that the stored contents can be seen from the outside. In this structure, the plastic film is not beaten when beaten in water to regenerate the paperboard.
Since it is also difficult to separate and remove only the film, the entire pack cannot be regenerated and there is no other processing method than burning it as waste. In addition, components that adversely affect the environment, such as nitrogen oxides, may be generated during incineration of plastics, causing environmental destruction.

The board pack of the present invention has a structure in which a plastic film is unnecessary by providing a window on the surface of the board so that the contents can be seen from the outside. Therefore, there is no possibility of causing environmental destruction by plastic. In addition, although a small amount of vinyl acetate emulsion is included as an adhesive used to mold the board pack, the polyvinyl acetate emulsion coexists with the water-soluble polymer, so that even after drying, Since it has high hydrophilicity and its content is very small relative to paperboard, it can be beaten in water. For this reason, the entire amount of paperboard can be recycled and used, which meets the demand for resource saving.

Furthermore, when discarded after repeated use, paperboard and adhesive do not contain compounds containing chlorine or nitrogen atoms even when incinerated, and therefore contain components that have a negative effect on the environment, such as nitrogen oxides. This is preferable from the viewpoint of environmental protection since there is no possibility of the occurrence of the harmful effect.

Further, as described in detail above, since the blanks in all the processes are processed in a state of being fitted into a mold, the precision of the dimensions and the shape is higher than that of the conventional manual product, and the protrusion of the bent corner or the like is obtained. Since there is no display at all, it is suitable for display on a hanger and for display on a flat surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings and embodiments. FIG. 1 shows a flow sheet of the board / pack packaging machine 1 of the present invention, FIG. 2 shows a front view of blanks, and FIG. 3 shows a perspective view of a board / pack containing four AA batteries as contents.

Here, as an example of the board pack packaging machine and the packaging method, a case where a board pack containing four AA batteries is produced will be described. Packaging machine 1
Is a blanks feeder 2, a conveyor 3, as shown in FIG.
It comprises a blanks folding machine 4, an adhesive applicator 5, a battery inserter 6, a board / pack molding machine 7, and an adhesive crimping machine 8. The contents stored in the board pack obtained by the packaging machine 1 are not limited to dry batteries, but can be applied to packaging of various articles such as small electric products (electric small items) and daily necessities.

A blank 9 for a dry battery is formed by punching a coated white ball made of a single sheet of paperboard into a shape as shown in FIG. 2, and a large number of blanks 9 are set up in the blank feeder 2. It is loaded in a state. The blanks 9 are made of only paperboard, and the board pack is formed by molding and pressing and solidifying with an adhesive, and no other material such as a plastic sheet is used. The windows 20 shown in FIGS. 2 and 3 are provided so that the batteries contained therein can be seen from the outside. The upper and lower skewer-shaped slits 21 and 21 'are provided by passing the board pack through a display bar. It is an opening for display. In addition, the folding line at the time of molding the board / pack is shown by a dotted line in the figure.

The conveyor 3 circulates between the two chain wheels 19, 19 'so that the surface is horizontal. A number of dies 10 are attached to the outer surface of the conveyor 3 and move together with the conveyor 3.
While the mold 10 moves on the conveyor 3 above the 19 ', the blanks 9 are supplied to the mold 10 to perform each processing operation, and the conveyor 3 is moved below the wheels 19, 19'. In this state, the mold 10 is empty. The conveyor 3 moves intermittently, and processing operations other than a part of the adhesive application operation and the folding operation at the time of board / pack molding are performed while the conveyor 3 is stopped, that is, the blanks 9 are stationary. ing.

An arm having a suction cup 18 for sucking from the blanks feeder 2 automatically controls pressurization and decompression applied to the suction cup in conjunction with the operation thereof, and
Are taken out one by one and set in the mold 10. The blanks 9 are transferred to the blank folding machine 4 while being set in the mold 10.

The blanks folding machine 4 is composed of a press machine 11 and a folding machine 12, and the blanks 9 are pressed by a press machine 11 from above onto a portion 22 serving as the front surface of the dry cell storage unit 15 and crimped to a mold. The space is depressed and the dry cell storage space 13 is formed. The blanks 9 are intermittently moved while being fitted in the mold 10, and are turned by the folding machine 12.
In the rising part of the blanks generated by the press machine,
The peripheral portion 23 that is not in close contact with the mold 10 is folded back. At that time, the sheet is once folded deeply so as to be maintained in a predetermined shape even after the external force is removed. This is an important operation for accurately forming the shape of the board pack. If necessary, the folded portion may be held in a predetermined shape by a holder until the upper half 24 of the blanks 9 is folded and pressed.

With the folded blanks 9 held in a predetermined shape as described above, the conveyor 3 transfers the blanks 9 to the adhesive applicator 5 where the adhesive is applied to predetermined portions. The adhesive applied here must have such a property that it can be beaten in water together with the paperboard even after drying. This is because the entire packaging material of the board pack is recycled into paper and used here. In this case, chlorine and nitrogen atoms are used in a vinyl acetate polymer emulsion containing a water-soluble polymer whose main component is poval and carboxymethyl cellulose. An adhesive containing no compound containing is used. The reason why the water-soluble polymer is added to the vinyl acetate-based polymer emulsion is to adjust the viscosity and to improve the beating property when the paperboard containing the solidified vinyl acetate-based polymer emulsion is recycled.

The use of such an adhesive in the formation of a board / pack makes it possible to recycle all the raw materials of the pack into paperboard and use them repeatedly, and to incinerate waste after being used several times. However, it does not generate pollutantly harmful nitrogen oxides and does not contain other components that have an adverse effect on the environment. It should be noted that hot melt adhesives, which are frequently used as adhesives in recent years, are difficult to beat in water and hinder the recycling of paperboard, so that they are not suitable as the adhesives for board packs of the present invention.

The application mechanism of the adhesive applicator 5 is not particularly limited, but a system in which a transfer mechanism is interposed is preferable in order to uniformly apply the aqueous dispersion emulsion. The emulsion-type adhesive is once wound up to a uniform thickness with a doctor blade on the adhesive take-up roller 25, and the adhesive is applied to the application part of the blanks 9 by the transfer roller 26 in which a sponge is applied to the application part of the adhesive. Attach. This operation is performed while the conveyor 3 is moving. After the adhesive is applied, the battery is transferred to the battery insertion machine 6, and four AA batteries are inserted into the battery storage space 13.

After the application of the adhesive, the blanks 9 are transferred to the molding machine 7 after a necessary drying time including the battery storage operation is taken in order to dry a part of the water contained in the emulsion to enhance the adhesive strength. During this transfer, the upper half 24 of the blank 9 to which the adhesive has been applied (the part on the back side of the board pack) 24 is folded back over the content storage space fitted in the mold, and A battery board pack 16 including 15 is formed. When the dry cell housing 15 is fixed by the mold during the next conveyor stop time, the ends 17 and 17 ′ on both sides of the folded blanks 9 are pressed from the outside to match the ends. Board pack with exactly matching ends and including storage box 15
16 is formed in the correct shape. This is also one of the important requirements of the present invention.

The adhesive crimping machine 8 comprises three crimping machines.
When the adhesive is solidified by the heat-pressing operation, the board pack 16 containing the dry batteries is completed. During the period from when the battery blanks 9 are supplied to the mold 10 to when the board pack 16 is obtained, the blanks 9 are intermittently moved while being fitted into the mold 10 and most of the processing is performed within the stop time. Since the operation is performed, the time required for each processing operation is set to be substantially the same. When a plurality of press machines are used, since a large amount of water is contained in the adhesive emulsion, a certain length of press time is required to solidify the adhesive. For this reason, it is necessary to perform a plurality of pressing operations in order to match the operation of the conveyor 3 that moves intermittently.

The board pack 16 whose production has been completed is forcibly pushed out of the mold 10 when the conveyor 3 is in a state of half a rotation around the chain wheel 19 ', and falls on the carry-out conveyor to be carried out. You. FIG. 3 shows a perspective view of the completed board pack 16. Although the packaging material does not include a transparent plastic sheet such as a conventional blister, the batteries stored inside can be observed from the windows provided in the pack. In addition, the display can be displayed on a slit or a hook at the top of the board pack through a display bar, and even when the bottom is upright on a flat surface as shown in the figure, it can be displayed on a flat table because it is stable.

[0045]

The present invention relates to a packaging machine and a packaging method for a board / pack for storing various articles such as small electric appliances and other daily necessities, or a board / pack produced by the manufacturing method thereof.
The pack does not use any transparent plastic film by providing a window on the surface that allows the interior to be seen. Since only a small amount of adhesive that can be beaten in water is contained as a component other than paperboard, it can be recycled into paperboard and used repeatedly, which is suitable for demands for resource saving. Further, since a compound containing chlorine or a nitrogen atom is not contained, there is no possibility of producing a component which adversely affects the environment such as nitrogen oxides even when incinerated, which is preferable from the viewpoint of environmental protection. Furthermore, since it is processed in a state where it is set in the mold in all processes, the accuracy of dimensions and shape is higher than conventional manual products, and there are no protrusions at the bent corners. Can be displayed side by side.
