Description

TECHNICAL FIELD The present disclosure relates to a tubular outer bag, and more particularly to a tubular outer bag that wraps a plurality of products while fixing the relative positional relationship between the products to form a unit. In addition, the present disclosure is a product-filled outer bag in which a product is wrapped in a cylindrical outer bag, and a product-filled outer bag rolled, rolled, or zigzag with a flat cross section of the product-filled outer bag. Concerning serpentine products. Further, the present disclosure relates to a manufacturing method thereof and a method of supplying a bag body, which is a product, from an outer bag containing the product.

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. 25 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 addition, it takes time and labor to fasten the bundled bag with a rubber band when putting it into the outer bag, to open and close the fitting when putting it into the outer bag, to pack it into a box, and to apply a waterproof film. .

In addition, in the bag supply process, the outer bag with the waterproof film was taken out, the fittings were removed, and the rubber bands were removed to return the bags with fittings to individual states. was necessary. 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.

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. 25 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.

(Third step)
It is preferable to place the bag inside the U-shaped or V-shaped base material with one of the left and right side ends of the bag directed downward. Since the bags can be neatly aligned using gravity, the bags are more orderly aligned within the outer bag containing the product. That is, the cylindrical outer bag 11 with fittings is unfolded, and is positioned inside the U-shaped or V-shaped base material 15 along the longitudinal direction Y of the base material 5 by the alignment device 68. The bags are stacked continuously or intermittently in a row so that (p1, p2, p3, p4, . . . , pn) partially overlap. FIG. 17 shows a form in which the bags (p1, p2, p3, p4, . . . , pn) are continuously stacked in a line. Here, the bags (p1, p2, p3, p4, . . . , pn) are conveyed one by one on a conveyer 65 located downstream of the bag making machine (not shown). . The bags on the conveyer 65, for example, the bags p4, p5, p6 and p7 are put inside the base material 15 in order.

Furthermore, the longitudinal direction Y of the base material 25 is the same as the longitudinal direction X of the cylinder with the base material 25 as a reference.

(First step)
An outer bag wound product 55 of the cylindrical outer bag 21 with fittings for outer wrapping wound around the bobbin 56 is prepared. A cylindrical outer bag 21 with fittings for outer packaging has two fittings, and the fittings 4a and 4b are engaged with each other so that the fittings 4a and 4b are positioned at both side ends, respectively. The cylinder is flattened and wound on the bobbin 56 . The cylindrical outer bag 21 with fittings for outer packaging is drawn out in the longitudinal direction X of the cylinder and delivered to the claw opening 66.例文帳に追加When the fittings 4a and 4b are separate from the base material 25, the first step includes a step 1A of preparing a tubular film or a half-cut film to which the fittings 4a and 4b are not adhered, and a step 1A of preparing a tubular film. or Step 1B of attaching a fitting tape to the half-cut film.

(Second step)
With regard to the tubular outer bag 21 with fittings for outer packaging that has passed through the claw opening 66, the fittings 4a and 4b are disengaged, so that one side 25b of the base material 25 divided into two is horizontally spread, The other piece of material 25a is spread horizontally over one of the substrates 25b. One of the substrates 25b is fed to pinch rolls 62a. The other substrate 25a is also fed to pinch rolls (not shown).

(Third step)
One of the substrates 25b is formed into a flat sheet shape, and the fittings 24a and 24b located on both widthwise end sides of the one substrate 25b are bag bodies (p1, p2, p3, p4, . . . ). It is preferable to place the bag on one of the substrates 25b so that it is located on the left side and right side of pn) respectively. That is, one of the substrates 25b is unfolded and along the longitudinal direction Y, by the alignment device 68, the pouches (p1, p2, p3, p4, . . . , pn) are partially overlapped. Alternatively, the bags are intermittently stacked in a row. FIG. 18 shows a form in which the bags (p1, p2, p3, p4, . . . , pn) are continuously stacked in a line. Here, the bags (p1, p2, p3, p4, . . . , pn) are conveyed one by one on a conveyer 65 located downstream of the bag making machine (not shown). . The bags on the conveyer 65, for example, the bags p4, p5, p6, and p7 are sequentially placed on one of the substrates 25b.

(Fourth step)
While moving in the longitudinal direction Y in a state in which a plurality of bags 23 are placed on one of the substrates 25b, the one of the substrates 25b that has been moved in the longitudinal direction Y at the same time is covered, and a fitting tool is attached by a claw hook 67. Preferably, 24a, 24b are articulated. The outer bag 300 containing the product is obtained by engaging the fittings 24a and 24b. The product-filled outer bag 300 with the fittings 24a and 24b engaged is degassed inside the product-filled outer bag 300 when passing through the pinch rolls 62b and 62c, and the volume becomes smaller. The cylindrical outer bag 21 with fittings for outer packaging is divided into upper and lower parts as one base material 25b and the other base material 25a. In operation, the bag 23 can be placed inside the tubular outer bag 21 .

(Fifth step)
