Abstract

PROBLEM TO BE SOLVED: To realize the quick and sure change of printing contents against the change of the specification in a commodity and restrict the change of a packaging material as few as possible by a method wherein the printing onto the packaging material and the packaging of the commodity are executed continuously. SOLUTION: On the film 2, the feeding of which is started from a roll 1, first of all, predetermined printing contents are printed at a printing part 3. The printing part 3 carries out a printing on the film 2 with a laser printer by means of electronic information and the change of printing contents can be done in one unit of a commodity by means of a data inputting part 4. The film 2, the printing on which has been finished, is fed in succession as is printed to a packaging mechanism at an upper stage. The packaging mechanism consists of a bag making part 10, a cutting-off part 11 and an end sealer 12 so as to pack the commodity 9 in the film 2 and then delivered to a discharging conveyor 13. A printing process and a packaging process are executed continuously. No change of the roll 1 is done at the change of the commodity. By changing printing contents in succession, a multikind and small quantity production can be dealt with.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous printing and packaging apparatus for printing predetermined characters, marks, pictures or the like on a packaging material before or during packaging of goods.

[0002]

2. Description of the Related Art A conventional packaging apparatus merely wraps a product using a packaging material on which printed contents such as predetermined characters, marks or pictures have been printed. For example, in a printing apparatus, the print content is printed on a long film at regular intervals to form a roll, and the roll is separately attached to a packaging apparatus to package the product. If the product to be wrapped or the specifications (seasonal or taste type, delivery destination, quantity display, etc.) change, the printed content will naturally change, and if you remove the roll currently in use and replace it with another roll Attach it to the packaging device and resume packaging. For this reason, it is necessary to store a plurality of rolls having different print contents in the packaging device. In the case of packaging a product with packaging material that has already been printed after bag making, as in the case of the roll, packaging materials having different printing contents for each product specification are stored and replacement work is required. I was

[0003]

Replacing a packaging material such as a roll in a packaging apparatus is a labor- and time-consuming operation, and is not preferable in view of efficiency. In addition, since packaging materials such as rolls usually have a minimum lot unit, multiple units of packaging material must be purchased for each type. This makes it difficult to secure a storage place and significantly increases the cost of purchasing packaging materials. What's more, the printed content does not fit in time,
If not used thereafter, all packaging materials having the print contents decided to be abolished will be wasted, and there is a problem that a large loss cannot be avoided.

[0004] Therefore, (1) the print content can be quickly and reliably changed in response to a change in the specifications of a product, especially the same product, and even in such a case, (2) replacement of packaging materials such as rolls is unnecessary or required minimum. (3) We examined the packaging equipment for commodities so as to reduce the storage cost and the purchase cost of packaging materials and avoid waste.

[0005]

SUMMARY OF THE INVENTION As a result of the examination, what has been developed consists of a packaging material feeding mechanism, a packaging material printing mechanism, and a product packaging mechanism using the packaging material, and printing and printing on the packaging material. This is a continuous printing and packaging apparatus that continuously performs the packaging of the product with the packaging material obtained. Printing on packaging materials
Perform immediately before or during packaging of the product. There is no limitation on the types of the packaging materials and the products. For example, plain or monochromatic packaged packaging materials are sequentially fed, printed for each packaging material, and packaged. Also, in the case of the above-mentioned film example, the entire print content is printed on plain film, but the print content is not affected by small changes in products (seasonal display, taste type display, etc.) A different print content for each product may be additionally printed on the film subjected to the above.

[0006] The printing method is letterpress printing using a plate, offset printing (lithographic printing) or gravure printing (intaglio printing),
What can print on a packaging material without using a plate, such as an ink jet printer or a laser printer, can be used. Monochrome printing, multicolor printing, or full color printing is performed on the packaging material. In the case of printing using a plate, the print content can be changed simply by replacing the plate. In the case of printing using an inkjet printer or a laser printer, the print content can be easily changed by changing the electronic information that determines the print content. The electronic information is created by an information processing device provided separately, and is input directly to the continuous printing and packaging apparatus of the present invention or via a storage medium to be changed, or is directly input to the information input device provided in the continuous printing and packaging apparatus. It is created and changed by the built-in information processing device from the data obtained. Further, the print content may be changed by a method of selecting necessary print information from a plurality or various types of print information stored in the continuous printing and packaging apparatus.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram showing a pillow packaging device to which the continuous printing packaging device of the present invention is applied. In this example, the printing mechanism is arranged in the lower part, and the packaging mechanism is arranged in the upper part.

[0008] The film 2 started to be fed from the roll 1 arranged at the lower right in FIG. The printing unit 3 in this example prints on the film 2 with a laser printer using electronic information.
The print information created separately by the information processing apparatus is attached to the print unit 3 by the data input unit 4 so that the print content can be changed for each product.

Although it depends on the packaging material, since the film 2 made of a synthetic resin is used in this example, the printed portion (surface) of the film 2 is coated in the coating section 6 for the purpose of further protecting the printed contents. The printed content is covered with a protective film obtained by applying a surface protective material 7 and solidifying the surface protective material 7 in a drying oven 8. The formation of the protective film adds printability, water resistance, ventilation blocking property, and the like to the film 2. Since printing is performed immediately before packaging, the film 2 may be plain. Since the print contents can be sequentially changed by the change in the printing unit 3, there is no need to replace the rolls 1 and only one kind of plain rolls 1 is required, so that the storage cost is greatly reduced.

[0010] After the printing of the print contents is completed, the film 2 is continuously fed as it is to the upper packaging mechanism. The packaging mechanism receives the product 9 conveyed from the upper left in FIG. 1 on the back side of the film 2 in the bag making section 10 and rounds both sides, and joins the both sides by a center seal roller to open both ends. The product 9 is placed in the film 2. In this state, the film 2 is still continuous back and forth. Then, in the cutting section 11, the film 2
Is cut, and the edges cut by the end sealer 12 are joined. After the product 9 has been packaged, the product 9 is sent out by the discharge conveyor 13, and a series of operations is completed.

As can be seen from the above, the film is continuously fed from the roller to the end of packaging the product, and the printing process and the packaging process are performed continuously. Since there is no need to change the rolls when changing products, it is possible to change the printing contents one after another, so that it is suitable for high-mix low-volume production and can flexibly cope with changes in sales strategies for products. In addition, since there is no need to store a large amount of previously printed film, there is a great advantage that purchase costs and storage costs can be significantly reduced.

In this embodiment, the printing mechanism is divided into a lower part and the packaging mechanism is divided into an upper part in accordance with the arrangement of each part. In the pillow packaging apparatus, a printing mechanism may be provided on the back surface of the bag making section, and printing may be performed on a film immediately before or during packaging. In this case, the printing mechanism and the packaging mechanism are arranged in a single row in a positional relationship of the front and back with the film interposed therebetween. The configuration shown in FIG. 1 is suitable for the case where the installation space can be taken up in the vertical direction, and the configuration in which the printing and packaging mechanism is arranged on the front and back as shown above is suitable for the case where the installation space can be taken up in the horizontal direction. In addition, it is also possible to arrange a printing mechanism on both sides of the film to perform double-sided printing.

[0013]

According to the present invention, it is not necessary to replace the packaging material in accordance with the product change, and the necessary type of packaging material may be only plain or pre-printed packaging material. This has made it possible to significantly reduce the costs and eliminate unnecessary rolls even if the product sales strategy changes. For example, in the past, it took about one hour to replace a roll. However, according to the continuous printing and packaging apparatus of the present invention, only the plate or electronic information needs to be changed in accordance with the content of the print, and especially, the change of the electronic information is instantaneous. Therefore, the print content can be changed without stopping the line. Thereby, productivity can be greatly improved.
