In general, primary packaging refers to the form in which products intended for sale are directly packaged. Secondary packaging refers to the form in which the products in the form of primary packaging are further packaged in boxes or bags according to the determined quantity. Goods are delivered to consumers in the form of primary or secondary packaging. In addition, tertiary packaging refers to the form in which products in the form of secondary packaging are placed in packaging boxes or the like for purposes such as bulk handling, warehousing, and transportation according to the determined quantity. In addition, a product that is in the form of primary packaging may be in the form of tertiary packaging instead of being in the form of secondary packaging.

For example, after winding the cylindrical side surface of a small cylindrical roll (corresponding to a "product") around a packaging film, the side surface of the packaging film is heat-sealed, and furthermore, it is positioned on the upper surface side and the lower surface side of the cylinder. There is a technique for primary packaging of small rolls by closing and heat-sealing packaging films (for example, see FIGS. 24 to 29 of Patent Document 1).

For bag makers, the product to be sold is the bag as the packaging material (see, for example, Patent Document 2). If the product is the intended product, the bag should be called a "product" to distinguish it from products that are not packaging materials (ordinary products, hereinafter also referred to as non-packaging material products). There is Moreover, the package which wraps a bag body may be called an outer bag.

Before a bag with fittings containing a non-packaging material product is displayed at a retail store, first, (1) bag-making process: the bag-making manufacturer manufactures the bag body and further accommodates it in the outer bag, (2) ) Transportation process 1: Deliver the bag body to the manufacturer of the non-packaging material product, (3) Bag supply process: Remove the bag body from the outer bag, (4) Filling process: Fill the bag body with the non-packaging material product, (5) Transportation process 2: The usual route is to transport the non-packaging material product filled in the bag to a retail store and then to general consumers.

The conventional bag-making process was performed in the following procedure. That is, bags with fittings, which are products produced by a bag-making machine, are once stocked in a container such as a tray, and are manually bundled into a fixed number of bags. The product bags with fittings, which are bundled by a certain number of sheets, are fixed by a binding means such as a rubber band, and then put into an outer bag with fittings, after which the fittings of the outer bag are attached. Closed. Furthermore, a plurality of outer bags with fittings are packed into a box. The box is shipped after being covered with a waterproof film to prevent dust and dirt from adhering and to prevent water from entering. All of these steps required manual labor.

In addition, the conventional bag feeding process was performed in the following procedure. That is, in order for a manufacturer of a non-packaging material product to fill a bag with a fitting with a non-packaging material product, the waterproof film is peeled off, the outer bag is removed from the box, the fitting of the outer bag is removed, and the bag is bundled. The bag with the fittings is taken out, the bundling means such as a rubber band is removed, and the bags with the fittings are returned to individual states. All of these steps also required manual labor.

On the other hand, it is also possible to further include a partition forming step of providing a second partition at a location corresponding to the non-arranged portion. There is a case where it is desired to manage a plurality of bags that are continuously or intermittently stacked in a row so that the bags, which are products, partially overlap each other, in units of a predetermined number of sheets, for example, 100 sheets. In such a case, it becomes easy to arrange a predetermined number of bags between the second partition and the adjacent second partition. The second partition is preferably formed by heat-sealing the inner wall surfaces of the substrates facing each other while pressing a heat sealer against a portion corresponding to the non-arranged portion. Alternatively, the partition may be formed by bonding the inner wall surfaces of the substrates facing each other. Further, it is more preferable to arrange the non-arrangement portions on both sides of the partition.

A separation perforation may be further provided at the location where the second partition is provided. A predetermined number of bags, which are products, are accommodated in the cylindrical outer bag, and by cutting off the perforations, subdivision management is facilitated. It is preferable to form the separation perforation after providing the second partition. It is possible to prevent the separation perforation from disappearing when the second partition is formed by heat welding.

In general, primary packaging refers to the form in which products intended for sale are directly packaged. Secondary packaging refers to the form in which the products in the form of primary packaging are further packaged in boxes or bags according to the determined quantity. Goods are delivered to consumers in the form of primary or secondary packaging. In addition, tertiary packaging refers to the form in which products in the form of secondary packaging are placed in packaging boxes or the like for purposes such as bulk handling, warehousing, and transportation according to the determined quantity. In addition, a product that is in the form of primary packaging may be in the form of tertiary packaging instead of being in the form of secondary packaging.

For example, after winding the cylindrical side surface of a small cylindrical roll (corresponding to a "product") around a packaging film, the side surface of the packaging film is heat-sealed, and furthermore, it is positioned on the upper surface side and the lower surface side of the cylinder. There is a technique for primary packaging of small rolls by closing and heat-sealing packaging films (for example, see FIGS. 24 to 29 of Patent Document 1).

For bag makers, the product to be sold is the bag as the packaging material (see, for example, Patent Document 2). If the product is the intended product, the bag should be called a "product" to distinguish it from products that are not packaging materials (ordinary products, hereinafter also referred to as non-packaging material products). There is Moreover, the package which wraps a bag body may be called an outer bag.

Before a bag with fittings containing a non-packaging material product is displayed at a retail store, first, (1) bag-making process: the bag-making manufacturer manufactures the bag body and further accommodates it in the outer bag, (2) ) Transportation process 1: Deliver the bag body to the manufacturer of the non-packaging material product, (3) Bag supply process: Remove the bag body from the outer bag, (4) Filling process: Fill the bag body with the non-packaging material product, (5) Transportation process 2: The usual route is to transport the non-packaging material product filled in the bag to a retail store and then to general consumers.

The conventional bag-making process was performed in the following procedure. That is, bags with fittings, which are products produced by a bag-making machine, are once stocked in a container such as a tray, and are manually bundled into a fixed number of bags. The product bags with fittings, which are bundled by a certain number of sheets, are fixed by a binding means such as a rubber band, and then put into an outer bag with fittings, after which the fittings of the outer bag are attached. Closed. Furthermore, a plurality of outer bags with fittings are packed into a box. The box is shipped after being covered with a waterproof film to prevent dust and dirt from adhering and to prevent water from entering. All of these steps required manual labor.

In addition, the conventional bag feeding process was performed in the following procedure. That is, in order for a manufacturer of a non-packaging material product to fill a bag with a fitting with a non-packaging material product, the waterproof film is peeled off, the outer bag is removed from the box, the fitting of the outer bag is removed, and the bag is bundled. The bag with the fittings is taken out, the bundling means such as a rubber band is removed, and the bags with the fittings are returned to individual states. All of these steps also required manual labor.

Furthermore, the conventional filling process was performed in the following procedure. That is, individual bags with fittings are supplied to the bag body supply section of the filling machine. This process also required manual labor. The bags with fittings that are taken out one by one from the bag supply section of the filling machine are opened and filled with non-packaging material products. This process is performed by a filling machine.

In particular, the rubber band or the like causes the bag with fittings to bend and become peculiar, and it has been necessary to return it to a flat shape. Furthermore, the bag with the fitting that was in contact with the rubber band or the like was wrinkled, and sometimes had holes. In this way, work mistakes and product losses were likely to occur frequently. Furthermore, every time the bag with fittings is set in the filling machine, it is necessary to return to the fitting opening process for the next outer bag and repeat the work manually, which is time-consuming and laborious. was As a result, personnel expenses increased, resulting in high costs, and work errors were unavoidable. In addition, it was difficult to secure human resources due to the shortage of manpower, and the cost increased further.

Furthermore, the outer bag itself needs to be manufactured, which requires the same labor and cost as the bag product. In addition, various types of outer bags must be stored together with the waterproof film, and management is forced in a warehouse, which is extremely costly and time-consuming.

In addition, since the waterproof film, shipping box, and outer bag are discarded after the filling process, a large amount of resources are wasted.

In addition, since the binding, packing, boxing, opening of the box, and opening of the outer bag were performed manually, there was a risk of stains caused by human beings.

Therefore, the present disclosure (1) realizes speed-up of the packaging bag production line by reducing the labor of human work, stabilizes the production speed, and reduces manufacturing loss due to human work mistakes and (2) prevention of cost increase due to bag making and storage of the outer bag and saving of labor for management thereof.

Furthermore, for those who make bags, the task of bundling the bags is not required, and the accompanying inspection process is also unnecessary.

Furthermore, since the air in the outer bag is degassed by winding the outer bag containing the product, the contact state between the inner wall of the outer bag and the bag body and the contact state between the bag bodies are deviated during transportation. Therefore, when the bag is unsealed and the bag is taken out, the state in which the bag is stuffed can be reproduced as it is.

By providing at least two rows of bags by providing a partition, it is possible to prevent the bags from being mixed in another row. In addition, when supplying the bags, it is possible to realize a supply speed that is more than a multiple of the number of rows, compared to a single-row type product-filled outer bag.

A process for forming a heat-sealed seal will now be described with reference to FIG. The thermal fusion/sealing device 98 has, for example, three regions having different temperatures in the order of a low temperature portion 98a, a high temperature portion 98b, and a low temperature portion 98a along the length direction X of the tubular shape. The high-temperature portion 98b performs thermal fusion cutting of the base material (the fusion cutting portion is indicated by reference numeral 19), and the low-temperature portion 98a heat-welds the inner wall surfaces of the facing base materials to seal (heat-welded sealing portion is formed). 45). A heat-sealed sealing portion is arranged next to the fused portion. More preferably, the non-arranged portion 40 is arranged next to the heat-sealed portion. Further, this manufacturing method further includes a step of printing a mark on a portion corresponding to the non-arrangement portion, and in the step of forming the heat-sealed portion, when the mark portion is detected, the base material is melted and cut. It is preferred to start the process of forming the heat-sealed seal with. When the mark is detected, the step of forming the melted/heat-sealed sealing portion is started, so that the heat-sealed portion is formed with a deviation of 10 to 15 mm from the mark. In the present embodiment, "sealing" means not only completely sealing both ends in the longitudinal direction of the cylindrical outer bag, but also closing the outer bag to such an extent that it prevents the bag from jumping out of the outer bag. including being A peelable sealing portion may be provided instead of providing the heat-sealed sealing portion 45 . In the step of forming the peelable seal portion, a peelable seal is applied to the portion corresponding to the non-arranged portion, and then cut to form a peelable seal portion at the end to form the outer bag containing the product. obtain.

(Method of supplying bag)
A method of supplying bags according to the present embodiment will be described with reference to FIG. The supply method of the bag body according to the present embodiment is such that the product-filled outer bag 100 according to the present embodiment or the wound product 50 of the product-filled outer bag according to the present embodiment is pulled out while the interlocking portion or the outer bag is pulled out.
