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. 13, 14 and 15. FIG. FIG. 13 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 hygienic condition of the articles. It is a series of steps to stop.

FIG. 14 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. 15 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 an air blowing means is added in the plastic bag, and the air pressure is used to attach or print a label from the outside of the plastic bag with a stamper. 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 body, a printing device (stamper) 2 for labeling or printing on the lateral surface of the plastic bag 1, and an upper side of the plastic bag 1. A blower device 3 is provided on the opening side of the. Predetermined articles 4 are placed inside the plastic bag 1 .

Under this configuration, the air 32 is sent into the plastic bag 1 from the air outlet (nozzle portion) 31 of the air blower 3 . The pressure inside the plastic bag 1 rises due to the wind pressure of the air 32 sent from the nozzle part 31, and the entire plastic bag 1 expands. 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. As will be described later, a stamper 2 affixes or prints a label on which predetermined information such as an address and an article name is written on 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.

2, 3 and 4 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. 1 is an enlarged cross-sectional view of FIG.

In FIG. 2, 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. 3 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 to the position D by the 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 of the plastic bag 1. It may be moved from the position of ₂ to the position of _D1 , and the label may be affixed in balance with the wind pressure P.

In this way, the stamper 2 moves forward when the adhesive layer 22 of the label 21 first adheres to the side surface of the plastic bag 1, and the reaction force, which is the fixing condition, is obtained by the wind pressure (air pressure) 32. FIG. 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. It is supported in contact with the side surface of 1.

FIG. 4 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. This is due to the use of a printing machine.

In FIG. 4, if 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 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. become. A predetermined side surface of the plastic bag 1 is in contact with or close to the printer head 23 and is printed on the surface of the plastic bag 1 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 a force F that the stamper 2 approaches from the right side in the same drawing so that the stamper 2 is brought closer to the side of the plastic bag 1. _Printing may be performed by moving from the position of _D2 to the position of D1.

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, the gap between the tip of the ink jet nozzle and the plastic bag 1 may be used for printing.

FIG. 5 is an explanatory diagram of an information fixing device according to the second embodiment of the invention. In FIG. 5, the basic configuration of the information fixing device is the same as that shown in FIG. 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 .

A difference from the embodiment of FIG. 1 is that a tray (shallow container) 55 is provided under the plastic bag 1 in FIG. Even if the air pressure 32 is applied to the plastic bag 1 from the upper opening side by the air blower 3 to inflate the plastic bag 1, depending on the rigidity and flexibility of the plastic bag 1, it may sway left and right and back and forth in the drawing. A problem of instability may also occur during pasting or printing.

Therefore, in the present invention shown in FIG. 5, a tray 55 is provided on which the plastic bag 1 is placed for stability. Although the illustrated tray 55 is shown in cross section, a square tray or a tray-like tray will suffice in practice. Also, the size, the height of the periphery, etc. may be appropriately determined according to the material, strength, etc. of the plastic bag.

5, the relationship between the plastic bag 1 and the stamper 2 is the same as explained with reference to FIGS. 2, 3 and 4. FIG.

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. The basic configuration is the same as that of FIG. 1, but FIG. 6 shows a state in which the air pressure 32 sent from the blower 3 is sent to the inner surface of the plastic bag 1 and even pressure is applied. 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 swelling of the bag 1, 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.

Also, the air blocking portion 34 shown in FIG. 6 may be applied to the configuration shown in FIG.

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.

In FIG. 7, the blower device 3 is installed in an inclined state. By sending air pressure 32 of the blower 3 toward the position of the stamper 2, the area required for labeling or printing is quickly and stably inflated, thereby flattening the side wall of the plastic bag 1 during labeling or printing. It can be kept as flat as possible.

Also, the configuration in which the air blowing portion is inclined as shown in FIG. 7 may be applied to the configuration shown in FIG.

FIG. 8 is a diagram showing an example in which an information fixing device according to one embodiment of the present invention is used in a conveying line.

In FIG. 8, a stamper 2 for labeling or printing a plastic bag 1 is arranged at a predetermined position on a conveying line 6 . Further, above a predetermined portion of the transfer line 6, the air blower 3 is supported by a movable guide 35. As shown in FIG. The plastic bag 1 is connected to wires 12 by clips 11 at the four upper corners of the bag. Wires 12 connected to the four corners are fixed at their upper ends to hooks 13, and hooks 13 are movably attached to guide rails 14. As shown in FIG.

By supporting the four corners of the plastic bag 1 upward with wires, the air flow 33 from the air blower 3 can be efficiently guided into the bag 1 and the sides of the bag can be kept flatter. That is, the stability can be increased during labeling or printing.

The plastic bag 1 containing the articles 4 is moved on the transport line 6 by, for example, a roller conveyor or a belt conveyor. Therefore, the movement of the hook 13 on the guide rail 14 and the movement of the transfer line are synchronized. Further, the blower device 3 may be retracted along the guide 35 when not needed.

FIG. 9 is a diagram showing an example in which the information fixing device according to the second embodiment of the invention is used in a conveying line.

In FIG. 9 as well, as in the basic configuration shown in FIG. 8, a stamper 2 for labeling or printing a plastic bag 1 is arranged at a predetermined position on the conveying line 6 . Further, above a predetermined portion of the transfer line 6, the air blower 3 is supported by a movable guide 35. As shown in FIG. The plastic bag 1 is connected to wires 12 by clips 11 at the four upper corners of the bag. Wires 12 connected to the four corners are fixed at their upper ends to hooks 13, and hooks 13 are movably attached to guide rails 14. As shown in FIG. Further, a tray 55 is arranged under the plastic bag 1. - 特許庁That is, the plastic bag 1 is placed on the tray 55 and moved on the transfer line 6 .

Therefore, by supporting the four corners of the plastic bag 1 upward with wires, the air flow 33 from the air blower 3 can be efficiently guided into the bag 1 to keep the side surfaces of the bag flatter. By placing the lower surface of the bag 1 on the tray 55, the stability of the bag 1 itself is enhanced, and swelling due to wind pressure can be stabilized. That is, the stability can be increased during labeling or printing.

As in FIG. 8, the plastic bag 1 containing the articles 4 is moved on the transport line 6 by, for example, a roller conveyor or a belt conveyor. Therefore, the movement of the hook 13 on the guide rail 14 and the movement of the transfer line 6 are synchronized. Further, the blower device 3 may be retracted along the guide 35 when not needed.

8 or 9 described above is such that a label is pasted or printed on a plastic bag 1 before being housed in a delivery container or the like. Therefore, when storing in a container for home delivery, a step of storing in a container or the like is required as a post-process.

FIG. 10 is a diagram for explaining an example of container accommodation after processing by the information fixing apparatus of the present invention.

A conveying line 61 for containers is provided ahead of the conveying line 6 for the plastic bags 1 to which labels are attached or printed. The container 5 is conveyed to the conveying line 61, and at a predetermined position, the plastic bag 1 to which the label is pasted or printed is put and accommodated.

Here, the wires at the four corners of the plastic bag 1 are removed, including the clips, and housed in a housing location (not shown) by movement of the upper hook 13 to be used in the next stamper process.

In the process of labeling or printing on the conveying line using the information fixing device described with reference to FIGS. 5 and 6, the air blocking section described with reference to FIG. Alternatively, the blower port described with reference to FIG. 7 may be inclined. A combination thereof may also be used.

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. 11 is a diagram for explaining the relationship between a bag and a container used in the information fixing device according to the third embodiment of the invention. In the information fixing apparatus shown in FIG. 11, 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 processing of information fixation is explained in FIG.

FIG. 12 is an explanatory diagram of an information fixing device according to the third embodiment of the invention. In FIG. 12, a blower 3 is provided at an upper opening of a plastic bag 1 in a container 5 into which predetermined articles 4 are put. 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 or printing is performed under a balance between the pressing force of the stamper and the pressure of the air introduced into the bag body, that is, the reaction force generated by the reaction force generating means. However, as in the third embodiment, the window 51 may be provided in the container 5 as a place for printing or the like. If printing can be performed by abutting the forces of the two at a specific portion of the opening where the printing is performed, only a predetermined frame may be provided and the bag inserted into the frame for printing. In short, it can be considered that the technical concept of the present invention includes the ability to create a state in which the pressing force for printing and the reaction force generated by the reaction force generating means are balanced.

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, such as paper. 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.
