Description

The present disclosure relates to a cylindrical outer bag, and particularly to a cylindrical outer bag that wraps a plurality of products while keeping the relative positional relationship of the products fixed to form a bundle. The present disclosure also provides a product-containing outer bag in which a product is wrapped in a cylindrical outer bag, and a rolled-up product of the product-containing outer bag obtained by rolling, casing, or winding the product-containing outer bag with a flat cross section; Concerning folded items. Furthermore, the present disclosure relates to a manufacturing method thereof and a method for supplying a bag for taking out a bag as a product from an outer bag containing a product.

Generally, the form of packaging products intended for sale directly is called primary packaging. Secondary packaging is a form of packaging a product in the form of primary packaging into a box or bag according to a predetermined quantity. Goods are delivered to consumers in the form of primary packaging or secondary packaging. Furthermore, tertiary packaging refers to a form in which secondary packaging products are placed in packaging boxes or the like for purposes such as bulk handling, warehousing, and transportation according to a predetermined quantity. Furthermore, a product that has been packaged in primary packaging may be packaged in tertiary packaging instead of in secondary packaging.

For example, after wrapping the cylindrical side of a small cylindrical roll (corresponding to the "product") around a packaging film, the sides of the packaging film are heat-sealed, and then the cylindrical roll is placed on the top and bottom sides of the cylinder. There is a technique for primary packaging small rolls by closing and heat-sealing packaging films (see, for example, FIGS. 24 to 29 of Patent Document 1).

Note that for bag manufacturers, the products they sell are bags that serve as packaging materials (for example, see Patent Document 2). If the bag is a product for which it is intended, the bag should be referred to as a "product" to distinguish it from products that are not packaging materials (normal products, hereinafter also referred to as non-packaging material products). There is. Moreover, the packaging that encloses the bag is sometimes called an outer bag.

Before a bag with a fitting device containing a non-packaging material product is displayed at a retail store, it first goes through the following steps: (1) bag making process: the bag manufacturer manufactures the bag body and then stores it in an outer bag; ) Transportation process 1: Deliver the bag to the manufacturer of the non-packaging material product, (3) Bag supply process: Remove the bag from the outer bag, (4) Filling process: Fill the bag with the non-packaging material product, (5) Transportation process 2: The usual route is to transport non-packaged material products filled into bags to retail stores and then to general consumers.

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

Furthermore, the conventional bag feeding process was performed according to the following procedure. In other words, in order for a manufacturer of non-packaging material products to fill a bag with a fitting, the waterproof film is removed, the outer bag is removed from the box, the fitting is removed from the outer bag, and the product is bundled. The bags with fittings are taken out, the binding means such as rubber bands are removed, and the bags with fittings are returned to their individual state. All of these processes also required manual labor.

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

However, in the bag-making process, the speed and accuracy of the bag filling process depended on the ability of each person performing the process, so the speed of the packaging bag production line was adjusted to match the processing capacity of each person. , I also need a break. As a result, productivity decreased, productivity tended to become unstable, and production efficiency was poor. Furthermore, the number of bags stored on the tray is limited due to the location of the storage and the instability of stacking, and a large space is required. Furthermore, it was time-consuming and labor-intensive to fasten the tied bag with a rubber band when putting it into the outer bag, open and close the fitting when putting it into the outer bag, pack it into a box, and apply a waterproof film. .

In addition, in the bag supply process, the outer bag packed in a box with a waterproof film was taken out, the fitting was removed, the rubber bands, etc. were removed, and the bag with the fitting was returned to its individual state, but all of this was done manually. It was necessary. In particular, bags with fittings were bent and bent by rubber bands, etc., and had to be returned to a flat shape, but all of this work was done manually. Furthermore, the bags with fittings that were in contact with the rubber bands or the like were sometimes wrinkled, and sometimes had holes. In this way, work errors and product losses were likely to occur frequently. Furthermore, every time you finish setting a bag with a fitting in the filling machine, you have to go back to the process of opening the fitting for the next outer bag and repeat the process manually, which takes time and effort. was. As a result, labor costs increased, costs increased, and work errors were inevitable. In addition, due to the labor shortage, it was difficult to secure human resources, which further increased costs.

Furthermore, the outer bag needs to be made into a bag itself, which requires the same effort and cost as bag products. In addition, various types of outer bags must be stored together with waterproof films and must be managed in a warehouse, which is very costly and time-consuming.

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

In addition, because the binding, outer bagging, boxing, opening of the box, and outer bagging were performed manually, there was a risk that human-caused stains would adhere.

Therefore, the present disclosure aims to (1) speed up the packaging bag manufacturing line by saving human labor, stabilize the production speed, and eliminate manufacturing losses due to human errors. (2) Manpower-saving, resource-saving, and resource-saving measures that reduce costs and suppress deterioration in the quality of the bag body; and (2) prevent cost increases due to the production and storage of outer bags, as well as save time and effort in managing them.

A joint 39 is formed by applying a peelable seal, adhesion, or heat welding to the base material 38b, and the base material 35 is formed into a cylindrical shape to obtain a product-containing outer bag 400. Here, it is preferable that the edges of both ends of the base material 35 in the width direction are placed on the stacked surfaces of the bags 33, 33' and are releasably sealed, bonded, or heat welded. The bags 33, 33' can be easily wrapped in the outer bag in a gassho-attached manner, and can be easily sealed, bonded, or heat-welded with a peelable seal. Therefore, it is easy to manufacture using a device with a simple structure. In the product-containing outer bag 400, the plurality of bag bodies 33, 33' are wrapped in a cylindrical outer bag 31 for outer packaging. The heat-sealed product-containing outer bag 400 is preferably sent to a touch roll 64, a pinch roll 62c, and a dance roll 61b. At this time, the joint portion 39 is placed in a horizontal state and sent. The inside of the product-containing outer bag 400 is deaerated, and its bulk is reduced. Although FIG. 19 shows a form in which the inner walls 38a and 38b of the base material 35 are separably sealed, bonded, or thermally welded to each other, it is also possible to form a form in which the inner wall 38a and the outer wall 38d are separably sealed, bonded, or thermally welded to each other, or , the inner wall 38b and the outer wall 38c may be separably sealed, bonded, or heat-welded.

In the method for manufacturing an outer bag containing a product according to the present embodiment, in the third step or step C, the bag is continuously or intermittently placed on the base material along the longitudinal direction of the base material so that a part of the bag body overlaps the base material. The bags are stacked in a row, and each time a predetermined number of bags are stacked, a non-placement part is provided at a predetermined interval where no bags are placed, and after the fourth step or step D, the outer bag containing the product is placed. On the other hand, the method may further include a partition forming step of providing a second partition at a location corresponding to the non-arranged portion. There are cases where it is desired to manage a plurality of bags that are products, which are stacked in a line continuously or intermittently so that some of them overlap, in units of a predetermined number, for example, 100 bags. In such a case, it becomes easy to arrange a predetermined number of bags between the second partition and the second partition next to it. The second partition is preferably formed by thermally welding the inner wall surfaces of the opposing base materials to each other while pressing a heat sealer against a location corresponding to the non-arranged portion. Alternatively, the partition may be formed by bonding the inner wall surfaces of opposing base materials to each other. It is more preferable that the non-arranged portions are arranged on both sides of the partition.

It is good also as having a process. A process for forming a heat-welded seal will be described with reference to FIG. 22. The thermal cutting/sealing device 98 has, for example, three regions having different temperatures in the order of a low temperature section 98a, a high temperature section 98b, and a low temperature section 98a along the length direction X of the cylindrical shape. The high-temperature section 98b thermally fuses and cuts the base material (the melt-cut location is indicated by reference numeral 19), and the low-temperature section 98a thermally welds and seals the inner wall surfaces of the opposing base materials (the thermally welded sealing section (Indicated by reference numeral 45). A heat-welded sealing portion will be placed next to the fusing location. More preferably, the non-placement portion 40 is placed next to the heat-welded sealing portion. Furthermore, this manufacturing method further includes the step of printing a mark at a location corresponding to the non-placement section, and when the location of the mark is detected in the step of forming the heat-welded sealing section, the base material is melt-cut. It is preferable to start the step of forming a heat-welded seal at the same time. When the mark is detected, the process of fusing and forming the heat weld seal is started, so the heat weld seal is formed 10 to 15 mm away from the mark. In this embodiment, "sealing" means not only completely sealing both lengthwise ends of the cylindrical outer bag, but also sealing them to the extent that the bag body is prevented from popping out from the outer bag. Including being present. Instead of providing the thermally welded sealing portion 45, a peelable sealing portion may be provided. In the process of forming a peelable seal part, a peelable seal is applied to the part corresponding to the non-placement part, and then a peelable seal part is formed at the end by cutting, and the outer bag containing the product is sealed. obtain.

With reference to FIG. 20, a method for supplying a bag according to this embodiment will be described. The bag supply method according to the present embodiment is carried out by pulling out the outer bag of the product-containing outer bag 100 according to the present embodiment or the rolled product 50 of the product-containing outer bag according to the present embodiment, while The method includes a 6th A step in which a portion other than the occlusal portion is opened, and a 7th A step in which the opened bags 3 and 3' in the outer bag are sequentially fed to a filling machine. As the product-containing outer bag, product-containing outer bags 200, 300, 400, and 500 may be used. Further, as the rolled product-containing outer bag, the rolled products 54, 57, and 70 of the product-containing outer bag may be used. When using the product-containing outer bag 400 or the rolled product 70 of the product-containing outer bag, the joint portion or a portion of the outer bag other than the joint portion is opened while pulling out the outer bag. Furthermore, a folded outer bag containing the product may also be used. When opening a part of the outer bag other than the occlusal part, a joint, or a part of the outer bag other than the joint, it is preferable to use a cutter to open the part. Further, if a fragile portion is provided in a portion of the outer bag other than the interlocking portion, a joint portion, or a portion of the outer bag other than the joint portion, the seal may be opened from the fragile portion. When a weakly adhesive, weakly adhesive, removable seal section is provided instead of the thermally welded seal section, the seal section can be easily opened. When unpacking is performed manually, work efficiency improves.

The outer bag may be opened using an opening assisting means 96. The second partition 41 may be peeled off when opening the package.

(6th A process)
As shown in FIG. 20, the steps for manufacturing the outer bag 100 or the rolled product 50 of the outer bag containing the product are performed in a manner opposite to the process for manufacturing the outer bag. That is, the rolled product 50 of the outer bag containing the product is sent to the dance roll 80, the pinch roll 81, and the touch roll 82, and then the fitting tool 4 lying on its side is raised up by the guide roll 83. Subsequently, the female member 4b and the male member 4a are each guided by the claw guide roll 84, and the interlocking portion of the fitting tool 4 or the outer bag other than the interlocking portion is removed and opened. In addition, when using the product-containing outer bag 400 or the rolled product 70 of the product-containing outer bag, the joint part or a part of the outer bag other than the joint part is opened while pulling out the outer bag. In step 6A, the state in which the bags 3, 3' are packed can be reproduced as is. The outer bag 1 is sent to a pinch roll 87 and a touch roll 93, and further wound up on a bobbin 91 to form a rolled product 90 of the outer bag 1. The used outer bag 1 wound around the roll product 90 of the outer bag 1 is discarded.

(7th A process)
The bags 3 and 3' inside the opened outer bag 1 are sequentially fed to a filling machine. Here, the leading bags p4 and p4' of the bags 3 and 3' placed on the base material 5 are detected by the bag detection tool 86, taken out by the suction tool 85, and placed on one end side of the positioning device 92. These become bags p3 and p3'. The bags p3, 3' placed on one end of the positioning device 92 are moved to the other end of the positioning device 92 by the suction tool 88, and become a bag p2. A bag detector 89 detects whether a bag exists at the position of the bags p2, p2'. The bags p2 and p2' are then supplied to a filling machine (not shown) as bags p1 and p1'.

In the 6A process and the 7A process, the product-containing outer bag 100 or the rolled product 50 of the product-containing outer bag can substantially reproduce the bag making machine, and the bag bodies 3, 3' are transferred to the filling machine. can be supplied at high speed. In other words, it can be said that the filling machine can substantially reproduce the inline design of the bag making machine. It can also be seen that the work of tying the bags is unnecessary, and the inspection process associated with it is also unnecessary.

This embodiment has a plurality of forms, and can be modified by appropriately replacing a part of each embodiment within a range that still achieves the effects of the present invention.

In this embodiment, a configuration has been described in which a cylindrical outer bag with a fitting tool is used to wrap a plurality of bags to form an outer bag containing a product. It is not limited to cards, but can also be applied to, for example, card-shaped products, and products that do not have a card shape are arranged in at least two rows at equal intervals and fitted to maintain that state. It is also possible to wrap it in a cylindrical outer bag with fittings or a cylindrical outer bag.
