Description

  The present invention relates to a method for producing a bonded package body such as a deep-drawn package body in which two films are bonded together and sealed in a reduced pressure state, such as an eel in a vacuum pack.

  There is a method for manufacturing unagi-boiled eel with a pack in which the eel is opened, white-baked, steamed and baked several times, dried until the surface becomes hard, and this is retort packed or vacuum packed. It has been proposed (see, for example, Patent Document 1). It is described that it can be stored for a long time if it is sterilized by heating after being packed.

  Some pack-packaged foods use a package in which transparent films are bonded together so that the products inside can be seen well, but they are printed on a predetermined area of the film on the front and back of the product. Some of them have a print display area in which the packaged product inside cannot be seen through.

  For example, the name, size (internal capacity), etc. of the product are printed on the surface, and finally the expiration date is printed. In addition, on the back surface, for example, a product name, cooking method, raw material, manufacturer, size (internal capacity) storage method, and the like are described, and a product barcode (unified product code) is printed.

  When a packaging body is formed by laminating films each having a print display area printed on the front and back, it is necessary to check whether the combination of the front and back printed films is correct or not. .

  However, depending on the product, only the notation according to the size of the packaged product is different, and there are other products with the same print display area. When the design is the same in this way, it is easy to check whether the combination of the front and back films is correct.

  For example, in the method of manufacturing a bonded package using eel grilled or white eel as a packaged product, the size of “(extra-large), (large), (medium)”, etc. depending on the size of the eel held inside For example, if the production line operator selects “Unagi (Large)” and starts work, the packaging operator will pre-order the product according to the production instructions in the packaging operation process. Prepare a packaging film with a name and other information printed on it.

  The wrapping film is composed of two separate films, front and back, and food (eel) is placed between them, and the four sides of the wrapping film, both vertical and horizontal, are sealed, and "Unagiya (Large)" The finished product is filled with the ingredients. In this case, the front and back packaging films are printed with a trade name and the size of the contents. Therefore, the packaging operator selects the packaging film based on the description of the production instruction and attaches it to the apparatus.

  Specifically, the roll of the front film is mounted in the pre-process of the production line, and the roll of the back film is mounted in the post-process. The surface film continuously drawn from the roll is formed into a concave mold by a mold. The processed “eel” is placed in the recess, and the vertical and horizontal four surfaces are sealed together with the back film drawn from the roll mounted in the subsequent process.

  A finished product comprising a vacuum-sealed packaging bag in which an end of the unnecessary film that is cut at a predetermined interval is cut and removed at the same time, and processed “eel” is sealed between the front film and the back film. it can. Under normal conditions, the product name and size printed on the front and back of the packaging bag are consistent with the food ingredients.

JP-A-53-99354

  However, as described above, even the same “eel” items have different sizes such as “(extra-large), (large), (medium)”, and it is necessary to prepare front and back packaging films corresponding to the size. In this case, the description items other than the characters specifying the size of the packaging film are almost the same, and only the difference in size is described. In particular, the character display of the size of the back film is small. For this reason, inadvertently, the display of the size of the front and back packaging films may be different.

The occurrence of such mistakes is thought to be caused mainly by the carelessness of workers,
(a) The items to be produced are the same product items, and the display contents of the packaging film are almost the same except for the size letters.
(b) To be prepared to change the size of the production target from oversized to oversized due to production, the packaging film must be installed without sufficient confirmation.
It is thought that it helps the occurrence of the mistake.

  In order to prevent this, a product production confirmation table was prepared, and the size description of the front and back films was confirmed before and after the start of production and at predetermined intervals during production. However, there is a possibility that the consciousness of confirmation may be weakened simply by writing a completed character of the size in the product manufacturing confirmation table in advance and putting a check to the effect of confirmation. That is, there is a problem that the consciousness of “confirmation” is lost due to the busyness, oversight and mistakes are neglected simply by checking, and further misunderstandings occur due to overlapping assumptions.

  In the present invention, in order to prevent such mistakes due to lack of awareness or misidentification at the time of confirmation, bonding can be performed by a machine to check whether the combination of the front and back printed films is correct or not. It aims at obtaining the manufacturing method of a package.

  INDUSTRIAL APPLICABILITY The present invention has an effect that it is possible to obtain a method for manufacturing a bonded package body that can be surely checked by a machine whether or not a combination of front and back printed films is correct.

It is explanatory drawing which shows the process of one Example of the manufacturing method of the bonded package body of this invention. It is explanatory drawing which shows the planar structure of the 1st film roll used in FIG. 1, and a 2nd film roll, and a figure is the 1st film roll by which the 1st film area | region used as the surface of goods at the time of goods manufacture was continuously arranged. , B is the 2nd film roll by which the 2nd film field used as the back of goods at the time of manufacture of goods was arranged continuously.

  In the present invention, the second film roll in which the second film region which is the back surface of the product is continuously arranged at the time of product manufacture is the first film region which is continuously arranged in the first film region which is the surface of the product at the time of product manufacture. Before the step of covering one film roll, a reading step of reading a first barcode printed in one film area and a second barcode printed outside the other film area, A step of stopping the step of the second film roll covering the first film roll when it is confirmed that the first barcode and the second barcode are not in a corresponding group. Thereby, it can be surely checked whether or not the combination of the front and back films printed in advance is correct.

  The bonded package of the present invention is not limited as long as it holds the packaged product between the first film region that becomes the surface of the product when the product is manufactured and the second film region that becomes the back surface of the product when the product is manufactured. In particular, on the first film area and the second film area, there is provided a print display area which is printed in each predetermined area so that the packaged product inside cannot be seen through. Therefore, there is a combination that matches the print display area of the front and back films. For example, the case where the product display is divided according to the size such as “(extra large), (large), (medium)” according to the size of the eel held inside as shown in the conventional example is applicable.

  In the production of the bonded package of the present invention, the product to be packaged is placed at a predetermined position of the first film roll in which the first film region is continuously arranged, and the second film region is continuously arranged. The second film roll is bonded to the second film region and the first film region to cover the first film roll, and the first film and the second film are deaerated and heat-sealed. What is necessary is just to provide the process of cut | disconnecting the goods which the 1st and 2nd film area | region bonded together from this heat-sealed continuous body.

  In such a first film roll and a second film roll, a first barcode is printed on either the first film roll or the second film roll, and the first film roll and the second film roll A second barcode corresponding to one of the other is printed in advance.

  As a preferred embodiment, the first barcode is printed on a print display area in one of the first film roll and the second film roll, and the second barcode is printed on the first film roll. The second barcode is cut out and does not exist in the product after the step of being printed and separated outside the other film region of the second film roll.

  A reading step of reading each of these two barcodes, that is, a first barcode printed in one film area and a second barcode printed outside the other film area, with a barcode reader; A step of stopping the step of the second film roll covering the first film roll when it is confirmed that the read first barcode and the second barcode are not in a corresponding group. Is performed before the step of covering the first film roll. Thereby, it can be surely checked by the machine whether or not the combination of the front and back films printed in advance is correct.

  As a preferred mode, the first bar code is a unified product code, and the second bar code is an in-store code. The in-store code is used only for confirmation in the production process, and it is possible to produce a normal bonded package without damaging the appearance of the printed decoration part on the surface of the final package after the separation process. .

  With the above configuration, the second barcode is printed outside the film area in order to print the in-store code on the part that is separated from the product at the end of manufacture using the unified product code used when the product is distributed. With a simple change of adding two bar code readers to the production line using the film, the machine can reliably check whether the front and back film combination is correct.

  Furthermore, in the bonded packaging body in which the first film roll is thicker than the material of the second film roll, and the deep packaging process is performed, the bonded packaging body is packaged in the first film region. The first film roll in which the part holding the product is a deep-drawn package that has been deep-drawn from other parts, and the first film region is continuously arranged before the step of placing the packaged product. By providing a process of deep drawing the film position that holds the packaged product, it is only a simple change that adds two barcode readers to the production line without changing the layout of the conventional production line. The machine can reliably check whether the combination of the front and back films is correct.

  FIG. 1 is explanatory drawing which shows the process of one Example of the manufacturing method of the bonded package body of this invention. FIG. 2 is an explanatory view showing a planar configuration of the first film roll and the second film roll used in FIG. 1, and FIG. 2A is a diagram in which the first film region that becomes the surface of the product at the time of product manufacture is continuously arranged. 1 film roll, b figure is the 2nd film roll by which the 2nd film area | region used as the back surface of goods at the time of goods manufacture was distribute | arranged continuously.

  As shown in FIG. 1, one end of a first film roll 1 in which a first film region serving as a product surface at the time of product manufacture is continuously arranged is unrolled and conveyed to a production line. As shown in FIG. 2a, the first film roll 1 is provided with two rows of first film regions 21 that become the surface of the product when the product is manufactured, and each predetermined region is provided on the first film region 21. And a printed display area in which the packaged product inside is not seen through.

  Outside the first film region 21, the first barcode 22 is printed at regular intervals. The first bar code 22 is an in-store code, and manages the first film roll 1 with a code that can be used only in the factory where it is manufactured or only in the factory of the related company.

  As shown in FIG. 1, the first film roll 1 conveyed intermittently passes through a first bar code reader 11 for confirming the first bar code 22 and reaches the deep drawing devices 12a and 12b. The deep drawing devices 12a and 12b form a deep drawing region 2 capable of holding a packaged product at a predetermined position in the first film region 21 when sandwiched from above and below, and are conveyed intermittently.

  Next, after putting the packaged goods 3 into the deep drawing region 2, the second film roll 4 is unwound and conveyed. As shown in FIG. 2 b, the second film roll 4 is provided with two rows of second film regions 23 that become the back surface of the product at the time of product manufacture, and each of the second film rolls 4 is predetermined on the second film region 23. It has a print display area that is printed in the area so that the packaged product inside cannot be seen through.

  A second barcode 24 is printed at the same position inside the second film region 23. The second barcode 24 is a unified product code (JAN code) and is used in the distribution process when this product is distributed.

  As shown in FIG. 1, the second film roll 4 conveyed intermittently passes through the second bar code reader 13 that confirms the second bar code 24 and reaches the reduced pressure laminating device 14. In this decompression laminating apparatus 14, the first film and the second film roll 1 are transferred while the first film roll 1 and the second film roll 4 are conveyed with the positions of the first film area 21 and the second film area 23 aligned. Adhesion and heat seal while degassing.

  The pasted packaging body is punched in the first and second film regions 21 and 23 by the separating devices 15a and 15b on the downstream side, and the product 10 is separated. At this time, since the first bar code 22 of the first film roll 1 is outside the punching area, it is not attached to the product 10 and is taken up together with the take-up roll 16.

  In such a process, information read by the first barcode reader 11 and information read by the second barcode reader 13 are converted into the first barcode 22 and the second barcode 24 by the control device 17. It is confirmed whether the sets match each other, and if it is determined that they do not match, the entire process is stopped including the step of the second film roll covering the first film roll.

  Thereby, it can be surely checked by the machine whether or not the combination of the front and back films printed in advance is correct.

  The machine can reliably check whether the pre-printed front and back film combination is correct.
