Description

The present invention relates to an information fixing device, and more particularly, to a packaging bag made of transparent plastic or the like for housing an article for home delivery, to attach a label indicating predetermined information necessary for managing the home delivery destination or the housed article. , or an information fixing device including one capable of displaying a label for the purpose of printing such information.

In recent years, home delivery systems have been developed in various industries. In the initial process of packing home delivery items, there are cases where the target items are directly stored and wrapped in cardboard boxes, etc., items are stored and wrapped in plastic bags, and then the plastic bags are stored and wrapped in cardboard boxes, etc. There are various forms. In particular, in order to hygienically protect deliverables and to preserve the freshness of perishables such as milk, tofu, meat, and vegetables, it is often used to store and wrap plastic bags inside Styrofoam boxes. It is

On the other hand, in order to reliably deliver the requested items to the client, the requested items are placed in a predetermined amount in a predetermined plastic bag, packed, and further processed as necessary for post-process work and management. It is necessary to make it possible to read the various information provided on each plastic bag. Generally, methods such as attaching a label or printing directly on a plastic bag are adopted.

Here, since the plastic bag is in the form of a thin sheet, when attaching the label, it is necessary to place a reaction force against the label pressing force, that is, a flat plate or the like, on the back surface of the side to which the label is attached. At that time, it is conceivable that the upper periphery of the plastic bag is folded back above a box-shaped container that serves as a delivery box, and a label is attached to the folded surface. However, since the surface of the label faces the inner side of the plastic bag after pasting, it is seen through the surface of the plastic sheet that is the opposite surface. At that time, it cannot be said that it is always easy to read due to a plastic bag with low transparency or overlapping of the paired surfaces.

In response to such a situation, as shown in Patent Document 1, a label printed with reversed characters on one side of a transparent film substrate is attached to the back side of a transparent plastic bag, so that the adhesive is adhered to the side ( A construction method has also been devised so that it can be read correctly when viewed from the front side of the bag).

In order to affix or print a label on the surface of a transparent plastic bag that is housed in a container, which is used as a shipping container, in an easy-to-see state and by an automatic machine, it is necessary to secure a reaction force against the pressing of the label or printing. . Therefore, it is difficult to provide a flat plate or the like on the inner surface of the plastic bag. Methods such as printing have also been devised.

JP 2005-241818 A

Generally, when articles for home delivery are collectively stored in a plastic bag, a label is affixed or printed on the front or back of the plastic bag so that the contents and destination can be recognized. However, it is difficult to automate labeling or printing on the surface of a thin, three-dimensionally inflated plastic bag, and labeling is generally performed manually. On the other hand, in the case of automation for work efficiency, it is possible to label or print the upper open portion of the plastic bag in the area folded outwards at the upper end of the container.

However, if the upper opening of the plastic bag is labeled or printed on the area that is folded outwards at the top edge of the container, the label will be printed on the back of the plastic bag if the opening of the plastic bag is closed after the item is loaded. If the label is attached to a low-transparency plastic bag or the surface of the plastic bag is wrinkled, it will be difficult to read the characters. Also, when printed on the back side of a plastic bag, the characters are reversed left to right, making it even more difficult to read.

On the other hand, when reverse character printing is performed using the transparent sheet disclosed in Patent Document 1, a special sheet and special character printing are required.

In this way, it is difficult to affix an easy-to-read label to the surface of a plastic bag that is to be stored in a container, which serves as a shipping container, using an automatic machine. However, it was difficult to see because it was attached to the inner surface of the bag.

It is a figure which shows the state of the plastic bag in a container for demonstrating background art. BRIEF DESCRIPTION OF THE DRAWINGS As a background art, it is a figure explaining an example of the conventional method of labeling a plastic bag.

First, the background of the present invention will be described with reference to FIGS. 10, 11 and 12. FIG. FIG. 10 is a diagram showing the steps of enclosing an article in a bag, attaching a label, and sealing the bag, for explaining the background art. For example, it shows a part of the process of processing products for home delivery on a transport path (transport line) 6 of a transport device that transports goods, such as a distribution center. It shows the process of sealing. The figure shows that a predetermined article 4 is put into a plastic bag 1 made of polyolefin or the like that is placed in a container 5 used as a mailing box, and information related to the article 4 that is required in the post-process and home delivery is shown. A label 21 describing information such as the destination address and name is affixed or printed on the surface of the plastic bag 1, and the opening of the plastic bag 1 is sealed in order to maintain the sanitary condition of the articles. It is a series of steps to stop.

FIG. 11 is a diagram showing the state of the plastic bags in the container, and shows the state in which the predetermined articles 4 have been put into the plastic bags 1 in the container 5 in the above process. In the figure, the plastic bag 1 is drawn so that it can be seen from the outside of the container 5 for the sake of convenience.

FIG. 12 shows an example of a conventional method of attaching a label 21 to a plastic bag 1. As shown in FIG. The figure shows a state in which the upper periphery of the plastic bag 1 is folded over the container 5 and the label 21 is attached to the folded surface. As shown here, in the conventional method, when the plastic bag 1 is sealed in a subsequent process, the label 21 is attached to the label 21 so that it becomes difficult to see the contents 4 inside, or the label 21 is folded when the plastic bag 1 is sealed. Moreover, since the label 21 is read from a surface different from the affixed surface of the label 21, it is difficult to read the necessary information.

The present invention is a completely different conception of the background art, in which a plastic bag is put in a frame, and a label is attached or printed directly to the plastic bag from the space between the frames of the frame by a stamper. .

In order to attach a label or print on the side surface of the plastic bag, air is blown into the plastic bag and the expansion of the plastic bag is utilized. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an explanatory diagram of an information fixing device according to one embodiment of the present invention. In FIG. 1, the basic configuration of the information fixing device includes a plastic bag 1 as an example of a bag, a frame 50 for containing the plastic bag 1, and a printing device ( A stamper 2 and an air blower 3 are provided on the upper opening side of the plastic bag 1. - 特許庁Predetermined articles 4 are placed inside the plastic bag 1 . Details of the frame body 50 will be clarified in FIG.

Under the configuration shown in FIG. 1, air 32 is sent into the plastic bag 1 from an air outlet (nozzle portion) 31 of the air blower 3 . The air pressure (air pressure) generated by the air 32 sent from the nozzle portion 31 increases the pressure inside the plastic bag 1, causing the entire plastic bag 1 to expand. The frame body 50 regulates the swelling of the plastic bag 1 as a whole and also functions to support the plastic bag 1.例文帳に追加Here, the plastic bag 1 is inflated, and the wall surface of the plastic bag 1 is substantially flat and balanced by a constant air pressure. Therefore, as will be described later, the stamper 2 affixes or prints a label containing predetermined information such as the destination and product name to the target portion 10 on the side surface of the plastic bag 1 .

In this example and the embodiments described below, articles 4 addressed to the delivery destination are put into a plastic bag 1 to be delivered in an upstream process, and the plastic bag 1 is labeled or printed. Alternatively, an empty plastic bag 1 may be labeled with or printed with information such as an address, and articles 4 matching the information may be thrown in in a post-process.

FIG. 2 is a diagram illustrating the relationship between the frame and the bag in the information fixing device according to the embodiment of the invention.

In FIG. 2, two examples of a frame 50a and a frame 50b are shown on the left side of the frame. Each frame of the frame body 50a regulates the accommodation range of the plastic bag 1, and also functions as an auxiliary support for the plastic bag 1 to stand on its own. Finally, by covering the upper part with a lid material, it becomes a simple container body.

Moreover, each frame of the frame 50b bridges between the upper parts. Each frame regulates the accommodation range of the plastic bag 1, works as an auxiliary support to make the plastic bag 1 stand on its own, and can also support the upper opening of the plastic bag 1 at the upper bridging portion. Even the frame body 50b can be used as a simple container body by finally covering the top with a lid material.

The frame 50a and the frame 50b both have the bottom plate 501, but may be a simple frame without the bottom plate 501. FIG. In this case, instead of the bottom plate, the conveying surface of the conveying path is used as the support for the lower surface. When it is finally made into a container body, refilling or the like is sufficient.

The right side of FIG. 2 shows an example of the configuration of an information fixing device using either the frame 50a or the frame 50b as indicated by arrows a or b. A frame 50b is used as an example of the frame 50 in the right diagram of FIG.

2, a plastic bag 1 as an example of a bag, a frame 50 for containing the plastic bag 1, and a printer (stamper) 2 for labeling or printing on the lateral surface of the plastic bag 1. 2, the air blower 3 is provided on the upper opening side of the plastic bag 1, which is the same as the configuration shown in FIG. In FIG. 2, the upper portion of the plastic bag 1 is folded back at the bridging portion of the upper portion of each frame of the frame body 50 . The folded portions are the same even when the frame body 50a is used, and it is sufficient to fold the upper four corners of the plastic bag 1 onto the upper portions of the respective frames and hook them.

In FIG. 2 as well, the air 32 is sent into the plastic bag 1 from the air outlet (nozzle portion) 31 of the air blower 3 . The air pressure (air pressure) generated by the air 32 sent from the nozzle portion 31 increases the pressure inside the plastic bag 1, causing the entire plastic bag 1 to expand. The frame body 50 regulates the swelling of the plastic bag 1 as a whole and also functions to support the plastic bag 1.例文帳に追加Here, the plastic bag 1 is inflated, and the wall surface of the plastic bag 1 is substantially flat and balanced by a constant air pressure. Therefore, as will be described later, the stamper 2 affixes or prints a label containing predetermined information such as the destination and product name to the target portion 10 on the side surface of the plastic bag 1 .

Whether or not the upper part of the plastic bag 1 shown in FIGS. 1 and 2 is folded may be determined depending on whether or not the plastic bag 1 can stand on its own due to its rigidity or the like.

3, 4 and 5 are diagrams for explaining the relationship between the plastic bag and the stamper in the information fixing device according to one embodiment of the present invention. FIG. 4 is an enlarged cross-sectional view of a stamper portion; 3 to 5 show the relationship between the side surface of the plastic bag 1 between the frames of the frame 50 and the portion 10 to be labeled or printed, and the frame 50 is omitted.

In FIG. 3, the stamper 2 is a labeling machine, and a label 21 having an adhesive layer 22 is prepared on the plastic bag 1 side. The plastic bag 1 is in a state where air pressure from the air blower 3 (not shown) is not yet applied, and there is a considerable distance between the side surface of the plastic bag 1 and the stamper 2 . Therefore, neither the wind pressure indicated by the arrow P from the inside of the plastic bag 1 in FIG.

FIG. 4 shows an example of using a labeling machine as the stamper 2, similar to FIG. It shows the state of At this time, since the plastic bag 1 has certain rigidity and flexibility, the plastic bag ₁ expands further from the position D1. This inflating action is stabilized at the preferred position of D2 where the tension of the material of the plastic bag ₁ and the force P due to the wind pressure 32 are balanced. A predetermined side surface of the plastic bag 1 is brought into contact with the adhesive layer 22, and the label is affixed by the balance between the pressure P and the force F approaching the stamper 2 from the right direction. Further, when the plastic bag ₁ reaches the position D1, the adhesive layer of the stamper 2 is moved by a force F that the stamper 2 approaches from the right direction in the figure so that the stamper 2 is brought closer to the side surface 10 of the plastic bag 1. It may be moved from the position of _D2 to the position of _D1 , and the label may be affixed in balance with the wind pressure P.

Thus, when the stamper 2 moves forward, the pressure-sensitive adhesive layer 22 of the label 21 adheres to the side surface 10 of the plastic bag 1 for the first time. In other words, the reaction force P (rightward in the figure) obtained by the wind pressure 32 and the pressing force F (leftward in the figure) for fixing by the stamper 2 are balanced, so that the adhesive layer 22 of the label 21 is attached to the plastic bag. 1 is supported in contact with the side surface 10 thereof.

FIG. 5 is a diagram for explaining the positional relationship between the bag body and the stamper in the information fixing device according to the embodiment of the present invention, similar to that shown in FIG. 4, but the difference from FIG. This is due to the use of a printing machine.

In FIG. 5, when the stamper 2 is a printer, a printer head 23 is provided. The stamper 2 is closer to the surface of the printer head 23 while the air pressure 32 is applied to the inside of the plastic bag 1 . By further inflating the plastic bag ₁ from the position D1, this expansion operation is stabilized at the preferred position D2 where the tension of the material of the plastic bag ₁ and the force P due to the wind pressure 32 are balanced. will do. A predetermined side surface 10 of the plastic bag 1 contacts or approaches the printer head 23 and the surface 10 of the plastic bag 1 is printed at a predetermined location by the pressure P and the printing force F of the stamper 2 .

Further, when the plastic bag ₁ reaches the position D1, the printer head 23 of the stamper 2 is moved by the force F that the stamper 2 approaches from the right direction in FIG. may be moved from the position of _D2 to the position of _D1 for printing.

Here, there are various printing methods such as an ink jet method, a dot impact method, and a type printing method, and any of them can be used. However, in most cases, the surface of the plastic bag 1 and the printer head 23 are printed with a predetermined pressure, but this is not the case in the case of the ink jet method. For example, when a predetermined gap is required, printing may be performed with a gap between the tip of the ink jet nozzle and the plastic bag 1 .

The relationship between the plastic bag 1 and the stamper 2 in FIGS. 3, 4 and 5 depends on the standing state due to the rigidity of the plastic bag 1, the strength of wind pressure (air pressure), and the pressing force including the printing function of the stamper. Labeling or printing takes place when the balance is achieved. On the other hand, the frame 50 has a self-supporting function due to the rigidity of the plastic bag 1, etc., and also functions as a support between the frames that are the pillars of the frame 50 as the plastic bag 1 swells. will also help to keep the .

FIG. 6 is a diagram showing an example in which an air blocking portion is provided in the air blowing portion of the information fixing device according to one embodiment of the present invention. 1 or 2 including the frame 50, but in FIG. It is the figure which showed the hanging state. As shown in the figure, air is sent from a wide area of the opening of the plastic bag 1, or means to reduce the escape of air is provided by providing an air blocking portion 34 or the like as illustrated in the figure. By maintaining a uniform internal pressure with the use of the squeegee, the bulge of the plastic bag 1 is kept in a more stable state. By stably maintaining the bulge of the plastic bag 1, the target part 10 of the plastic bag 1 becomes flatter and the label 21 can be stuck and printed in a stable state. A similar effect can be obtained by enlarging the bottom portion of the blower 3 (not shown) instead of providing the air blocking portion 34 here.

FIG. 7 is a diagram showing an example in which the blowing portion of the information fixing device according to one embodiment of the present invention is tilted to change the blowing direction.

The basic configuration including the frame 50 is the same as in FIG. 1 or 2, but in FIG. 7, the blower 3 is installed in an inclined state. By sending air pressure 32 of the blower 3 toward the position of the stamper 2, the target portion 10, which is the required area for labeling or printing, is quickly and stably inflated. The side walls of the bag 1 can be kept as flat as possible.

1 or 2 described above, the plastic bag 1 is put in the frame 50, and a label is attached or printed on the side surface of the plastic bag 1, and is used for conventional home delivery. When storing in a container or the like, a step of repacking into a home delivery container or the like is provided after labeling or printing. Therefore, the frame 50 may be used, and after the labeling or printing process, the frame 50 may be used and its upper surface, side surfaces, etc. may be appropriately covered with a plate material instead of the container.

In the above-described embodiment, labeling or printing is performed directly on the side surface of a plastic bag that is inflated by wind pressure. can be

FIG. 8 is a diagram illustrating the relationship between a bag and a container used in an information fixing device according to another embodiment of the invention. In the information fixing apparatus shown in FIG. 8, the container 5 in which the plastic bag 1 is placed has windows 51 having openings larger than the size of the label 21 in part of the four side walls. The process of fixing information is explained in FIG.

FIG. 9 is an explanatory diagram of an information fixing device according to another embodiment of the invention. In FIG. 9, a blower device 3 is provided at the upper opening of a plastic bag 1 in a container 5 containing predetermined articles 4 . Air 32 is sent from a nozzle portion 31 of the blower 3 . The pressure inside the plastic bag 1 is increased by the air pressure generated by the air 32 sent from the nozzle portion 31, and the entire plastic bag 1 is inflated. At this time, the maximum dimension of the plastic bag 1 in the fully inflated state is sufficiently larger than the inner dimension of the container 5, and a label is attached near the window 51 opened on the side of the container 5. A stamper 2 for attachment or printing is installed.

Due to the wind pressure inside the plastic bag 1, the plastic bag 1 is displaced from the window 51 opened in the side surface of the container 5 so as to protrude outward. Labeling or printing by the stamper 2 is performed through this window. With such a configuration, it is possible to omit the process of refilling the bag body into the container.

Note that various modifications (enlargement, reduction, substitution, selection, removal, etc.) may be made based on the technical idea of the present invention without being limited to the embodiments of the present invention described above. For example, in the above basic configuration, labeling is performed under a balance between the pressing force of the stamper and the pressure of the air introduced into the bag in the frame, that is, the reaction force generated by the reaction force generating means. Alternatively, although printing is performed, as in other embodiments, a window 51 may be provided in the container 5 as a place for printing, etc. If it is possible to create a state in which the reaction force is balanced, it may be considered to be included in the technical idea of the present invention.

In the above description, the plastic bag 1 made of plastic is taken as an example of the bag body. , and various materials can be used. Any material having a certain degree of rigidity may be used, for example, paper may be used as the material. This increases the degree of freedom in selecting the bag body, and increases the degree of freedom in selecting the bag body based on the contents, cost, or the like.

In the above description, the typeface to be labeled or printed is described as an example in which characters are viewed from the front, but instead of this, for example, mirrored characters or reversed characters (horizontally reversed and/or vertically reversed) can also be used. . By doing so, for example, when the printed or labeled portion is folded back and conveyed, the character information can be recognized through the bag body, which enhances convenience. In this embodiment, when attaching a label, it is preferable to use a highly permeable material for the label itself.

The embodiments described above are provided as examples for understanding the present invention, and the present invention is not limited to these embodiments but is defined by the claims. In addition, as long as they do not deviate from the technical idea of the present invention, configurations equivalent to those described in the claims are also included in the scope of protection of the present invention.
