[Technical field to which the invention belongs]

 The present invention relates to an original roll in which a synthetic resin film such as a vinyl chloride resin film is wound in a roll shape. More specifically, it is a standard for a film that is wound even when stacked inside or outside a warehouse. Relates to an original roll of synthetic resin film which can be discriminated at a glance.

[0002]

[Prior art]

 BACKGROUND ART Synthetic resin films such as vinyl chloride resin films are generally stored, transported, etc. as an original roll wound around a winding core for a predetermined length. Further, as shown in FIG. 4, the standard of the wound synthetic resin film (trade name, product type, thickness, width, winding length, etc.) is as follows: It was displayed by affixing a label 31 that describes the items necessary to show the standard.

[0003]

[Problems to be solved by the device]

 By the way, the above-mentioned raw fabric rolls are generally stored inside or outside a warehouse in a state of being stacked in several stages (that is, a state of being stacked) on a pallet or the like, as shown in FIG. Therefore, the labels attached to the surface of the original rolls stacked on the lower side or the inner side (that is, the original rolls with the surface not exposed) cannot be read. . In addition, even if the roll is stacked with the roll surface exposed, the label attached to the roll surface may not always be readable. That is, the label 31 can be easily read in the state of the original roll 11 (A) in FIG. 4, but the label 31 is below the original roll as shown in 11 (B). Labels cannot be read if they are stacked on the surface.

On the other hand, with respect to the label attached to the core, it is relatively easy to read if the attached label faces upward, but if the attached label faces downward, it is extremely difficult to read. It's hard to read. In addition, stacked original rolls do not necessarily have the same width, and a label attached to the core of a narrow original roll is extremely irrelevant regardless of the label orientation. It's hard to read. Further, not all of the original rolls have a shape in which the ends of the winding core project as shown in FIGS. 4 and 5, and for example, the end face of the wound film (that is, the end face of the original roll). In some cases, the end face of the winding core is flush. In such cases, the label may be attached to the inner surface of the core, but the label attached to the inner surface of the core may be attached to the outer surface of the protruding portion of the core with the protruding end. It's even harder to read than the label you're wearing.

As described above, even if the label having the standard is attached to the surface of the original roll or the core, only a few items can be read at a glance when the items are stacked. Yes, most of them are difficult to read. Therefore, in the stacked state, the standard of the film wound on the original roll cannot be discriminated, and the standard must be discriminated by moving the stacked original rolls. There were cases that I didn't get.

[0006]

[Means for Solving the Problems]

 The original roll of the present invention made in order to solve the above-mentioned problems, the items necessary for distinguishing the standard of the wound film are adhered to the end face of the original roll by sticking a film such as stamp ink. It is characterized in that it is displayed by directly printing with ink that does not cause it.

The original roll of the present invention is a film such as a vinyl chloride resin film for agricultural use, building materials, and other general miscellaneous goods, which can be directly printed on the end surface when the original roll is formed. It is limited to those that have been wound up. The width of the film to be wound is not particularly limited, and the length of the film is not particularly limited as long as it is equal to or longer than the length at which a printable end face is formed when the material roll is used. A film having a thickness of 0.5 mm or less, particularly preferably 0.2 mm or less is suitable for the original roll of the present invention. This is because when the film to be wound is extremely thick, the ink used for printing impairs the appearance of the edges of the product film. However, even if it is thick like a film (sheet) for a desk mat, if the edge of the film is cut off when it is made into a product through secondary processing, there is no problem even if the film is thick. Absent.

The film to be used as the raw roll is produced by a production method usually employed for producing a film, such as a calendering method, an extrusion method and an inflation method. However, since the original roll of the present invention prints directly on the end face, it is necessary to perform trimming and the like so that the end face is smooth.

The ink for printing on the end face of the original roll can be printed on the end face of the original roll and is not easily erased. It is necessary to select one that does not hinder the unwinding of the film. When printing with an ink that penetrates into the gap of the wound film and sticks the films together when printed directly on the end face of the original roll, unwind it from the original roll and use it. In the case of unwinding from the raw roll for secondary processing or secondary processing, not only the workability is significantly impaired, but in the worst case, the product film may be damaged.

The printing on the end face of the original roll may be at least on one end face of the original roll, but it is more preferable to print on both end faces. In addition, it may be possible to print on a part other than the end face of the original roll, specifically on the core or the surface of the original roll, but in particular, when the original roll surface is printed, it is printed. Since the area is not suitable as a product film, it should be avoided unless there is a special circumstance that printing must be done on the surface of the original roll. Even in the case of the original roll of the present invention, it is desirable to attach a label indicating the standard at a predetermined position, as in the case of the conventional original roll, as described later.

In the present invention, the printing on the end face of the original roll does not necessarily reach all the standards of the film wound up. For example, if it is decided that only the original rolls of the same type and the same thickness will be wound for the same length, only the width of the original roll will be printed on the end face. However, the standard of the film wound on the original roll can be determined. That is, the printing on the end face of the original roll of the present invention displays the minimum items necessary to determine the standard of the film wound on the original roll in a stacked state. If there is, it is enough. However, in this case, if they are not stacked, the standard cannot be discriminated.As described above, the label with the detailed standard is attached as in the case of the conventional material roll. There is a need. That is, by sticking a label showing detailed standards, even after each individual roll has been sold to its respective customer, it is wound up on that roll. There is nothing that makes film standards indistinguishable.

Note that the content printed on the end face of the original roll does not necessarily have to be represented by letters or numbers. For example, a standard corresponding to each color of ink used for printing may be determined, and a dot having a size that allows the color to be easily identified may be printed on the end face of the original roll. Of course, it is also possible to determine the standard corresponding to each number of points, and it is also possible to express by a combination of colors and letters.

The color and size of printing on the end face of the original roll are not particularly limited as long as it is a size that can be accommodated on the end face of the original roll and can be easily identified as described above. . The color that can be easily identified depends on the color of the film wound on the original roll and cannot be determined in a general way.However, in the case of a transparent film that is commonly used, white or silver type preferable.

The greatest feature of the original roll of the present invention is that the end face of the original roll is directly printed with an ink that does not bond the films to each other without using a label. Of course, if you fill in the necessary information on the label and then stick it on the end face of the original roll, it will be easy to determine the standard even when stacked, but you can put the label on the end face of the original roll. The film cannot be unwound as it is attached, and it takes time to peel off the attached label at the time of use or secondary processing. Moreover, if the stuck label cannot be completely peeled off and the adhesive of the label remains on the end face of the original roll (so-called “reduction of adhesive residue” occurs), the films are bonded together. Similar to the case of printing with such ink, the workability when unwinding from the original roll for use or unwinding from the original roll for secondary processing is significantly impaired. On the other hand, the original roll of the present invention directly prints using the ink that does not bond the film to each other, so there is no need to peel off the stuck label and there is no printing on the conventional end face. As in the case of the original roll, the work of unwinding the film from the original roll can be performed smoothly.

[Embodiment of the invention]

 Hereinafter, specific examples of the original roll of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an example of an original roll of the present invention. In the figure, reference numeral 1 indicates an original roll of the present invention, reference numeral 2 indicates a winding core, and reference numeral 3 indicates a surface of the original roll or a winding core. The affixed label, reference numeral 4, indicates the display showing the width of the film wound on the original fabric roll, which is printed on the end face of the original fabric roll.

A raw roll 1 shown in FIG. 1 is obtained by winding an agricultural polyvinyl chloride film having a thickness of 0.1 mm and a width of 400 cm around a paper winding core 2 for 300 m.

An indication 4 of “400” (cm) indicating the width of the agricultural polyvinyl chloride film wound on the original fabric roll 1 is provided on the end surface of the original fabric roll 1. This display 4 is stamped and printed with a rubber stamp using a silver stamp ink (“Stampia U silver color; trade name, manufactured by Sunbee Co., Ltd.). Although not shown, it is applied to both end faces of the original roll 1.

In the example shown in FIG. 1, only the width of the film wound around the original roll 1 is printed and displayed, but the display content is not limited to the width of the film, and is not required. In addition, the minimum items necessary to determine the standard of the film wound on the original roll 1 in the stacked state may be displayed.

Further, in the example shown in FIG. 1, since the label 3 showing the detailed standard is adhered to the surface of the original fabric roll 1 and the winding core 2, each individual original fabric roll 1 is sold individually. Even after it has been sold first, the standard of the film wound on the original roll 1 is not lost.

Further, since the original roll 1 shown in FIG. 1 has the indications 4 on both end faces, as shown in FIG. 2 and FIG. 3 (however, the indication 4 is omitted in FIG. 2). Even if they are stacked, the standard of the film wound on the original roll 1 can be discriminated at a glance from any end face direction, and the label 3 attached to the surface of the original roll can be determined. Even if they are stacked in this way, there is no problem in determining the film standard. 2 is a lateral view of the original rolls 1 shown in FIG. 1 stacked, and FIG. 3 is a view taken in the direction A of FIG.

The present invention has been described above by taking the raw roll of the polyvinyl chloride film for agriculture as an example. However, the present invention is not limited to the raw roll of vinyl chloride resin film used for purposes other than agriculture. In this case, any roll can be applied as long as it is a roll that is wound with a film that can be directly printed on the end face. However, when the wound film is used as a product as it is, if you print directly on the end face of the original roll that is wound with too thick film, the appearance of the product film will be damaged by the ink used for printing. Therefore, it is not preferable.

[0022]

[Effect of the invention]

 As described above, since the original roll of the present invention has the necessary information for distinguishing the standard of the wound film on the end surface, the original roll is stacked on the surface of the original roll or the core. Even if the attached label is difficult to read or unreadable, the standard of the wound film can be determined at a glance. Also, since the end face of the original roll is printed directly with an ink that does not bond the films to each other, the workability when unwinding the film is not impaired.
