  2. Description of the Related Art Conventionally, packaging bags for storing stored items such as packaged products disclosed in Patent Document 1 are often manufactured from, for example, a packaging film that has been subjected to various printing and the like and has a display function. As an example of such conventional printing, printing for displaying necessary items such as product name, raw material name, content, storage method, cooking method, manufacturer and various codes of the items stored in the packaging bag Printing for a beautiful design is known (for example, see Patent Document 2).

As a packaging film having such a display function, many packaging films having a laminated structure formed by bonding a surface film printed on an inner surface and another film with an adhesive or the like are known (for example, Patent Document 3). reference).
In addition, there is a packaging film in which a plain laminated packaging film is prepared as a conventional packaging film, and the outer surface of the packaging film is printed according to an order.
JP2003-11907. JP-A-7-315424. JP-A-3-72461.

  By the way, in recent years, with the development of point-of-sale information system and diversification of consumer needs, the stored items can be stored using packaging bags that can store these stored items corresponding to many different types of stored items. There is a demand for producing a large variety of small quantities of packaged products. For this reason, a packaging film printed in advance as disclosed in Patent Document 3 is prepared in advance, a packaging bag is manufactured using the packaging film, and the packaging bag is filled and stored If the product is simply produced, there is a problem that the inventory of packaging films more than necessary increases, while the inventory of packaging films of necessary kinds of stored goods becomes insufficient. There is also a problem that inventory of packaging bags and packages may increase due to a difference in sales prospects, or conversely, inventory may be insufficient. In addition, as disclosed in the above-mentioned Patent Document 1, there is the same problem as described above even when a package is manufactured by filling and storing a stored item in a packaging bag while manufacturing the packaging bag.

  On the other hand, when a packaging bag or a packaged article is manufactured using a packaging film that has been printed according to an order received on a plain outer surface as described above, there is a problem that the printed appearance is inferior compared to the case of printing on the inner surface. is there.

  This invention is made | formed in view of such a situation, Comprising: While manufacturing the packaging bag which has a display function, the objective is to pack the packaging goods manufactured by being filled and accommodated in a packaging bag. It is an object of the present invention to provide a packaged product manufacturing method and a packaged product manufacturing apparatus that can flexibly and reliably handle stored items.

  In order to solve the above-mentioned problems, a manufacturing method of a packaged product of the invention of claim 1 includes a main body film supplying step for supplying a main body film, a surface film supplying step for supplying a surface film having a display function, and the main body. A film aligning step for combining the film and the surface film, a packaging film forming and simultaneous supplying step for forming the packaging film by bonding the main body film and the surface film together and supplying the formed packaging film; The back film sealing step for forming the packaging film in a cylindrical body and sticking and sealing the side ends, the bottom sealing step for bonding and sealing the lower end opening of the cylindrical body, and the lower end opening are sealed.

A cutting step for separating from the other part of the covering film, a trimming step for bonding and sealing the upper end opening of the cut cylindrical body, and bending the upper end of the cylindrical body to the side surface of the cylindrical body It is characterized by comprising a tape attaching step for attaching with a tape.

  Moreover, the manufacturing method of the packaged product of invention of Claim 2 provides the rectangular parallelepiped cylinder formation process which forms the rectangular parallelepiped cylinder which comprises the said cylindrical body between the said back sticking sealing process and the said bottom sealing process. It is characterized by being able to.

  Furthermore, the manufacturing apparatus for a packaged product according to the invention of claim 3 manufactures a packaging bag by using a packaging film formed by adhering a surface film having a display function to the main body film, and the contents stored in the packaging bag. In a packaged product manufacturing apparatus for manufacturing a packaged product by filling and storing the main body film, a main body film supply means for supplying the main body film, a surface film supply means for supplying the surface film, the main body film and the surface film, A film matching means for bonding the body film, a packaging film forming means for bonding the main body film and the surface film together to form a packaging film, and forming the packaging film into a cylindrical body and attaching the side edges. Back sealing means for sealing together, bottom sealing means for sticking and sealing the lower end opening of the cylindrical body, and the lower end opening are sealed. A filling means for filling the cylindrical body with the stored material, a cutting means for cutting the upper end portion of the cylindrical body filled with the stored material and separating it from the other part of the packaging film, and Trimming means for sticking and sealing the upper end opening of the cylindrical body, and tape attaching means for bending the upper end of the cylindrical body and sticking it to the side surface of the cylindrical body with tape. It is said.

  According to the packaged product manufacturing method and packaged product manufacturing apparatus according to the present invention configured as described above, a plain main body film having no display function and a surface film having a display function are separately prepared and stored items are stored. Various surface films that are printed according to the product type are prepared, and the surface film corresponding to the product type of the stored product is selected immediately before filling the stored product, and the main body film and the surface film are adhered to each other to wrap the packaging film. Therefore, the main body film can be used in common regardless of the type of stored items. Therefore, the stock of the main body film can be greatly reduced. In that case, it is necessary to prepare a surface film for each kind of stored item, and there is a certain amount of inventory of the surface film, but it is possible to effectively reduce the total inventory amount combined with the main body film.

  In addition, since the surface film only needs to have a display function, it can be made much thinner than the thickness of the main body film and can be formed at a low cost. Therefore, even if there is a certain amount of the stock of the surface film, it is not bulky, the stock space of the surface film can be reduced, and the stock amount of the surface film can be reduced.

  Furthermore, since a common main body film can be made in common, a large amount can be manufactured collectively, so that the manufacturing cost can be reduced. Further, by providing a printing layer as a display function on the inner surface, the printed appearance can be maintained as well as in the case of conventional inner surface printing.

  Furthermore, although the number of steps of thermal laminating (thermal bonding) between the main body film and the surface film is increased, the packaging film forming means for performing this thermal laminating is provided in the packaging product manufacturing apparatus. The main body film and the surface film can be heat-bonded in a process continuous with the filling and packaging process, the number of substantially independent processes is not increased, and the filling speed is not lowered as compared with the conventional process.

  In this way, while producing a packaging bag having a display function, it is possible to flexibly and reliably handle a packaged product produced by filling and storing in a packaging bag, respectively, It is possible to effectively produce a wide variety and a small amount of packaged products.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.
FIG. 1 partially shows a packaging film used in an example of an embodiment of a method for producing a packaged product according to the present invention, (a) shows a packaging film, (b) shows a main body film, (C) is a figure which shows a surface film, and FIG. 2 is a figure which shows the formation pattern of the heat seal layer which is an adhesive layer formed in a surface film.

  The packaging product manufacturing method of this example manufactures a packaging product by filling and storing the stored items in the packaging bag while manufacturing the packaging bag, as disclosed in Patent Document 1 described above. The packaging film used in this method for producing a packaged product is a flexible packaging film having a display function. As shown in FIG. 1A, the packaging film 1 is formed in a laminated structure in which a main body film 2 and a surface film 3 are bonded. In that case, in the packaged product manufacturing method and packaged product manufacturing apparatus of this example, the main body film 2 and the surface film 3 are not bonded to each other but are prepared separately.

  As shown in FIG. 1B, the main body film 2 is a multilayer (in the illustrated example, three layers, but is limited to this) by laminating various films in consideration of storage stability and heat sealing. In the following description, it will be described as a three-layer structure). As for the thickness of the main body film 2 of this laminated structure, 50 micrometers-150 micrometers are preferable. For example, the main body film 2 is laminated to the gas seal layer 2b, a piercing protective layer 2a having a piercing property, a gas sealing layer 2b laminated on the piercing protection layer 2a to prevent permeation of oxygen and water vapor, and the gas sealing layer 2b. It is formed into a laminate film having a three-layer structure comprising a sealant layer 2c for heat sealing.

  In that case, nylon, polyester, polycarbonate, etc. can be used for the stab protection layer 2a, for example. Further, for the gas seal layer 2b, a vapor-deposited film such as aluminum foil, aluminum, or silica, a vinylidene film, a vinylidene-coated polypropylene film, or the like can be used. Furthermore, polyethylene, polypropylene, or the like can be used for the sealant layer 2c. For example, as a body film 2 of a packaging bag for storing coffee (beans, powders), nylon having a thickness of 15 μm as a stab protection layer 2a, aluminum foil having a thickness of 7 μm as a gas seal layer 2b, and polyethylene having a thickness of 60 μm as a sealant layer 2c Laminate film using is suitable.

  As shown in FIG. 1 (c), the surface film 3 is printed with a base film 3a and necessary information such as designs and varieties as described above on the base film 3a. The print layer 3b and the heat seal layer 3c formed by applying the base film 3a and the print layer 3b are formed in a three-layer structure (not limited to three layers). (It can also be formed in a multilayer other than three layers. In the following description, it will be described as a three-layer structure).

The base film 3a is made of a material that is relatively rigid and hardly scratches and is suitable for a packaging and filling machine. For example, a plastic film having a thickness of 12 to 40 μm such as polyester, nylon, or polypropylene can be used.
Any conventionally known printing ink can be used for the printing layer 3b.

As shown in FIG. 2, the heat seal layer 3c is printed in a predetermined pattern on the base film 3a and the print layer 3b. Therefore, the heat seal layer 3c is not printed on the entire surface of the base film 3a and the print layer 3b, and is partially pattern-printed at necessary portions.
For this heat seal layer 3c, a heat seal material suitable for the material of the piercing protective layer 2a, which is the surface film of the main body film 2 to which it is thermally bonded, is used. For this heat seal material, for example, a heat seal material based on EVA hot melt material is used for a wide range of protective layer materials, and when the piercing protective layer 2a of the main body film 2 is nylon, When a nylon hot melt adhesive is used as a base resin and the piercing protective layer 2a is polyester, a polyester hot melt adhesive is used as a base resin, and a gravure printing paint is blended with the base resin. A heat seal material can be used.

  In addition, when it is difficult to obtain a heat seal material that adheres well to the puncture protection layer 2a of the main body film 2, by applying a primer to the surface of the piercing protection layer 2a of the main body film 2, the heat seal material can also be adhered to other heat seal materials. It can also be improved to facilitate. In addition, when it is difficult to adhere the heat sealing material coating to the surface of the printing layer 3b, the heat sealing material can be applied after improving the adhesion using an anchor agent on the printing surface. In this case, the thickness of the heat sealing material to be applied is suitably 2 μm to 20 μm.

Next, the manufacturing method of the package in this example of the present invention will be described.
FIG. 3 is a diagram showing a flow for performing the method for manufacturing a packaged product of this example.
As shown in FIG. 3, in the manufacturing method of the packaged goods of this example, first, main body film supply process S1 and surface film supply process S2 are performed. The main body film supply step S1 and the surface film supply step S2 are performed at the same time, and the plain main body film 2 shown in FIG. 1B and the surface film 3 having the printed layer 3b shown in FIG. Both are supplied to the film alignment section. Next, film alignment process S3 is performed. In this film matching step, the piercing protective layer 2a of the main body film 2 and the heat seal layer 3c of the surface film 3 are combined with each other.

  Next, packaging film formation simultaneous supply process S4 is performed. In the packaging film formation simultaneous supply step S4, when the puncture protection layer 2a of the main body film 2 and the heat seal layer 3c of the surface film 3 are combined with each other by heat and pressure, the packaging film 1 is formed. At the same time, the formed packaging film 1 is supplied to the packaging bag manufacturing unit and the stored item filling and storing unit. Adhesion between the main body film 2 and the surface film 3 in the packaging film formation simultaneous supply unit is performed by heat and pressure adhesion.

  Each subsequent process in the method for manufacturing a packaged product is the same as the method for manufacturing a packaged product disclosed in Patent Document 1 described above. That is, the back-sealing sealing step S5 is then performed on the packaging film 1 supplied to the stored item filling and storing unit in the same manner as before. In this back sticking sealing step S5, the packaging film 1 is bent into a cylindrical shape, and both end portions thereof are stuck together by heat bonding and sealed. Next, a rectangular parallelepiped cylinder forming step S6 is performed. In this rectangular parallelepiped cylinder forming step S6, the packaging film 1 formed into a cylindrical shape in the same manner as in the past is formed from the cylindrical shape into a rectangular parallelepiped cylinder. Next, a bottom sealing step S7 is performed. In the bottom sealing step S7, the bottom end of the rectangular parallelepiped cylinder formed in the same manner as in the past is bonded to form a closed bottom portion of the packaging bag.

  Next, a filling step S8 is performed. In this filling step S8, the stored items are filled into a rectangular parallelepiped cylinder whose bottom is closed in the same manner as in the prior art. Once the rectangular parallelepiped cylinder is filled with a specified amount of storage, a cutting step S9 is then performed. In this cutting step S9, the predetermined position above the storage in the rectangular parallelepiped cylinder is cut (cut) as one packaging bag in the same manner as in the past, and from the other part of the packaging film 1 formed in the rectangular parallelepiped cylinder Disconnected.

  Next, a trimming step S10 is performed. In the trimming step S10, as in the conventional case, after the inside of the packaging bag made of a rectangular parallelepiped cylinder filled and cut is evacuated, the upper end opening of the rectangular parallelepiped cylinder is pasted and top sealed. . Thereby, the stored item is filled and stored in the package and sealed. Finally, a tape applying step S11 is performed. In this tape attaching step S11, the top-sealed upper end opening is bent and attached to the side surface of the rectangular parallelepiped cylinder with tape. Thus, a packaged product in which the stored items are filled and stored in the package is manufactured.

Next, an example of the packaging product manufacturing apparatus of the present invention will be described.
FIG. 4 schematically shows a part of the packaged product manufacturing apparatus of this example, (a) a drawing showing a packaging film forming simultaneous supply means, a rectangular parallelepiped cylinder forming means, and a storage material filling means, and (b) a rectangular parallelepiped. It is the figure which looked at the shape cylinder shaping | molding means and the stored item filling means from the IVB direction in (a).
The configuration of the packaged product manufacturing apparatus in this example is basically the same as the configuration of the packaged product manufacturing apparatus disclosed in Patent Document 1 described above. Therefore, the part of this example different from the structure of the packaged product manufacturing apparatus disclosed in Patent Document 1 will be described in detail, and the structure of the other parts can be easily understood with reference to Patent Document 1, so that the detailed description thereof Is omitted.

  That is, as shown in FIGS. 4 (a) and 4 (b), the packaged product manufacturing apparatus 4 of this example includes a main body film supply roll 5, a surface film supply roll 6, a film aligning means 7, and a packaging film molding. A simultaneous supply means 8, a rectangular parallelepiped cylinder forming means 9, a bottom seal means 10, a filling means 11, and a cutting means 12 are provided.

  The main body film supply roll 5 winds up the main body film 2 shown in FIG. 1B and rotates it when necessary to supply the main body film 2 to the packaging film forming simultaneous supply means 8. The main body film supply roll 5 is prepared in a relatively small number because the main body film 2 is used in common for some kinds of stored items. The surface film supply roll 6 winds up the surface film 3 shown in FIG. 1C and rotates it when necessary to supply the surface film 3 to the packaging film forming simultaneous supply means 8. Since the surface film 3 is used in accordance with several types and storage amounts of the stored items, many surface film supply rolls 6 are prepared for each number of types and storage amounts. That is, main body film supply process S1 and surface film supply process S2 are performed. Furthermore, the film aligning means 7 is constituted by a roll, and the piercing protective layer 2a of the main body film 2 and the heat seal layer 3c of the surface film 3 are aligned with each other by the film aligning means 7. That is, the film matching step S3 is performed.

  The packaging film forming simultaneous supply means 8 includes a pair of pressure rolls 8a and 8b. Although not shown, one pressure roll 8a is provided with a heater, and the pressure roll 8a is formed as a heating roll. Has been. And in the state which the stab protection layer 2a of the main body film 2 and the heat seal layer 3c of the surface film 3 were match | combined, the main body film 2 and the surface film 3 are heat-pressed with a pair of pressurization rolls 8a and 8b. The surface film 3 is thermally bonded to the main body film 2 to produce the packaging film 1. Further, the manufactured packaging film 1 is supplied to the rectangular parallelepiped cylinder forming means 9 by a pair of pressure rolls 8a and 8b. That is, the packaging film forming simultaneous supply step S4 is performed. When a material that generates heat by high frequency is used as the heat seal material, a high frequency welder can be used instead of the pressure rolls 8a and 8b.

  The rectangular parallelepiped cylinder forming means 9 is the same as the rectangular parallelepiped cylinder forming means in the packaging product manufacturing apparatus disclosed in Patent Document 1, and includes a cylindrical cylinder-forming jig 9a and a seal bar 9b. Then, the sheet-like packaging film 1 is first bent into a cylindrical shape by the tube-making jig 9a, and both end portions thereof are bonded and sealed by heat bonding of the seal bar 9b. Furthermore, the packaging film 1 formed in a cylindrical shape is formed into a rectangular parallelepiped-shaped cylinder by the cylinder-making jig 9a. That is, the back sticking sealing step S5 and the rectangular parallelepiped cylinder forming step S6 are performed.

The bottom seal means 10 is also the same as the bottom seal means in the packaged product manufacturing apparatus disclosed in Patent Document 1, and includes a seal bar 10a. Then, the lower end opening of the rectangular parallelepiped cylinder is bonded and sealed by heat bonding of the seal bar 10a. That is, the bottom sealing step S7 is performed.
The filling means 11 is also the same as the filling means in the packaged product manufacturing apparatus disclosed in Patent Document 1, and includes a filling cylinder 11a. Then, as shown in FIG. 5, the filling cylinder 11a is inserted into a cylindrical tube-making jig 9a, and a storage object such as coffee (bean or powder) is filled into the rectangular parallelepiped cylinder from the filling cylinder 11a. . That is, the filling step S8 is performed.

  The cutting means 12 is the same as the cutting means in the packaged product manufacturing apparatus disclosed in Patent Document 1, and includes a cutter 12a. And the upper end part of the rectangular parallelepiped cylinder in which the stored items are stored is cut (cut) as a single packaging bag by the cutter 12a at the predetermined position, and separated from the other parts of the packaging film 1 formed in the rectangular parallelepiped cylinder. It is. That is, the cutting process S9 is performed.

  Further, although not shown, the packaged product manufacturing apparatus 4 of this example is the same as the vacuuming unit, trimming unit, and tape applying unit in the packaged product manufacturing apparatus disclosed in Patent Document 1, respectively. Means. And after the inside of the packaging bag which consists of a rectangular parallelepiped cylinder filled and cut is evacuated by the vacuuming means, the upper end opening of the rectangular parallelepiped cylinder is pasted together by the trimming means to be top-sealed. Thereby, the stored item is filled and stored in the package and sealed. Further, the top-sealed upper end opening is bent by the tape applying means and is attached to the side surface of the rectangular parallelepiped cylinder with the tape. Thus, a packaged product in which the stored items are filled and stored in the package is manufactured.

  According to the packaged product manufacturing method and packaged product manufacturing apparatus 4 thus configured, the plain main body film 2 without printing (display function) and the surface film 3 having a display function after being printed. Are prepared separately, and various surface films 3 printed according to the type of the stored items are prepared, and immediately before filling the stored items, the surface film 3 corresponding to the type of the stored items is selected and these are selected. Since the packaging film 1 is formed by adhering the main body film 2 and the surface film 3, the main body film 2 can be used in common regardless of the type of stored items. Therefore, the stock of the main body film 2 can be significantly reduced. In that case, it is necessary to prepare the surface film 3 for each kind of stored item, and there is a certain amount of inventory of the surface film 3, but the total amount of inventory totaled with the main body film 2 can be effectively reduced.

  Moreover, since the surface film 3 only needs to have a display function, it can be made much thinner than the thickness of the main body film 2 and can be formed at low cost. Therefore, even if there is a certain amount of stock of the surface film 3, it is not bulky, the stock space of the surface film 3 can be reduced, and the stock amount of the surface film 3 can also be reduced. As an example, when considering a conventionally manufactured coffee package, coffee packages having a storage amount of 150 g, 200 g, 250 g, 400 g, and 500 g are manufactured. In that case, packaging films having the same width are used for three types of 150 g, 200 g, and 250 g, and packaging films having the same width wider than this are used for two types of 400 g and 500 g. The packaging film is formed by bonding a printed surface film to a plain body film. The surface film is about 20 μm thick, and the plain body film is thick. Is about 85 μm. Furthermore, there are five types of coffee beans. In such a case, conventionally, the estimated stock quantity of each of the 5 types of storage amount, 5 types of beans, and 25 types of packaging films is required. On the other hand, 25 types of surface films are required as in the conventional case, but only two types of main body films are required. Therefore, even if there is a difference in the prospects of the amount, the surface film becomes only an unnecessary stock, and since the main body film is common, the stock amount can be reduced and it can be used without waste. Thereby, the total inventory amount which the main body film 2 and the surface film totaled can be reduced effectively. Moreover, even if there is a certain amount of the stock of the surface film 3, the surface film 3 is thin and is not bulky, so that the stock space of the surface film 3 can be reduced and the stock amount of the surface film 3 can be reduced.

  Furthermore, since the common main body film 2 can be manufactured in large quantities, the manufacturing cost can be reduced. Moreover, since the printing layer 3b is provided on the inner surface, the printed appearance can be maintained as well as in the case of conventional inner surface printing.

  Further, although the heat laminating (thermal bonding) process between the main body film 2 and the surface film 3 is increased, the packaging film forming simultaneous supply means 8 for performing the heat laminating is provided in the packaging product manufacturing apparatus 4. The main body film 2 and the surface film 3 can be thermally bonded in a process subsequent to the process of filling and packaging the stored items by the manufacturing apparatus 4 of the manufacturing apparatus 4 so that the number of substantially independent processes does not increase and the filling speed is increased. There is no reduction compared to.

  In this way, while producing a packaging bag having a display function, it is possible to flexibly and reliably handle a packaged product produced by filling and storing in a packaging bag, respectively, It is possible to effectively produce a wide variety and a small amount of packaged products.

  In the above example, the packaging product manufacturing apparatus 4 of the present invention is basically the same as the configuration of the packaging product manufacturing apparatus disclosed in Patent Document 1 described above, but the present invention is not necessarily limited thereto. For example, the present invention can be applied to a packaged product manufacturing apparatus disclosed in JP-A-2002-144442. In short, the present invention can be applied to any conventionally known packaging product manufacturing apparatus as long as it is a packaging product manufacturing apparatus that manufactures a packaging product by filling the packaging bag with the stored items while manufacturing the packaging bag. Can be applied.

  In the above-described example, a rectangular parallelepiped cylinder packaging bag is formed. However, the present invention is not limited to this, and is applicable to cylindrical packaging bags and other packaging bags. can do. In short, the present invention can be applied to packaging of any stored item as long as the stored item is filled and stored in a packaging bag using a packaging film having a display function that is printed.

  Furthermore, the packaging film formation simultaneous supply step S4 and the packaging film formation simultaneous supply means 8 in the above example may be the packaging film formation step S4 and the packaging film formation means 8. In that case, a dedicated supply means may be provided separately as the packaging film supply means, or the packaging film 1 may be pulled and supplied by a means (not shown) for pulling down the rectangular parallelepiped tube.

Next, examples of the present invention will be described.
