Description

  The present invention relates to a paper tube around which an ornament such as a film, carbon fiber, synthetic yarn, paper, or the like is wound. More specifically, the present invention relates to a paper tube with an IC tag that can identify unique information of the ornament.

  Conventionally, traceability (manufacturing history) information has been provided on paper tubes for wrapping decorations such as film, carbon fiber, synthetic yarn, paper, etc., in order to investigate the cause of any problems that occur in the decorations. It may be necessary. Further, in order to perform distribution management and quality control of merchandise, a bar code label is attached, which is read by a bar code reader and managed by a computer. However, the barcode label has problems that it cannot be read due to dirt or peeling, and that the amount of information is small and data cannot be rewritten.

  In order to solve such problems, in recent years, there is a large amount of recorded information, and data tags can be freely rewritten and appended, and IC tags that can read information at high speed have come to be used. A paper tube with an IC tag has also been proposed for a paper tube around which a fitting is wound.

As such a paper tube with an IC tag, there is known one in which an IC tag is mounted on a cushioning sponge body inserted into the inner tube portion of the paper tube so as not to hinder the winding of the fitting. . (For example, patent document 1) Moreover, what stuck the IC tag directly on the inner cylinder wall surface of a paper tube is known. (For example, Patent Document 2)
JP 2001-203523 A JP 2004-75366 A

  However, it takes time to embed the IC tag of Patent Document 1 in the sponge-like body, and it is troublesome to insert the sponge-like body in which the IC tag is embedded into the inner tube portion of the paper tube. In addition, since the IC tag is attached to the inner cylinder wall surface of Patent Document 2 because it must be attached to the curved surface portion, the IC tag may be peeled off due to an adhesion failure without being reliably attached. Furthermore, there is a possibility that information may malfunction due to static electricity generated by damage due to chucking or friction with the spindle.

  The present invention has been developed with the object of solving the above-described problems. An IC tag can be easily attached to a paper tube, and the attached IC tag is protected by a paper layer without being damaged. With an IC tag that is durable and secures the original radio wave transmission / reception range of the IC tag, reliably reads the information specific to the fitting, and can be wound without causing any obstacle to the fitting. The purpose is to provide a paper tube.

  As means for solving the above-mentioned problems and achieving the object, the present invention is characterized in that a slit is engraved in the end thick part of the paper tube main body, and a non-contact IC tag is inserted into the slit. Developed and adopted a paper tube with an IC tag.

  Further, in the present invention, in the paper tube with an IC tag configured as described above, the slit is formed in an arc shape along the outer peripheral surface of the paper tube main body, and the IC tag includes the upper and lower sheets. A flexible paper tube with an IC chip and an IC chip and an antenna inside, and a display portion indicating the insertion position of the IC tag is provided on the thick portion. Developed and adopted a paper tube with an IC tag.

  Since the present invention inserts an IC tag into a slit carved in the thick part of the end of the paper tube, it can be inserted very easily. The inserted IC tag is a paper layer. Since the IC tag is sandwiched by the elasticity of the paper layer, it can be prevented from coming off. Further, since the IC tag is inserted into the arc-shaped slit and becomes an arc shape, the radio wave transmission / reception range with the reading device is widened, so that information can be read / written reliably. Furthermore, since the IC tag has flexibility, it can be smoothly inserted along the arc-shaped slit.

  Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 to 5, wherein 1 is a cylindrical paper tube main body formed by winding a belt-like base paper into a spiral in several layers, An arc-shaped slit 3 along the outer peripheral surface is formed in a substantially intermediate portion of the end thick portion 2. The position of the slit 3 is a thick portion on the back surface in the drawing, but may be a thick portion on the front surface or thick portions on the left and right side surfaces. The slit 3 is engraved with a predetermined width, depth and length by an arcuate thin blade (not shown).

  4 is a non-contact IC tag to be inserted into the slit 3, and comprises an IC chip 5 and an antenna 6 as shown in FIGS. Is formed from a material having excellent flexibility and hermetically sealed.

  The IC chip 5 has a memory and stores unique information, for example, manufacturing date, manufacturing lot, product name, and other information. The antenna 6 can generate current by resonating with radio waves transmitted from a reading device (not shown), and can activate the IC chip 5. The activated IC chip 5 stores information stored in the memory. Is transmitted from the antenna 6 to the reading device by radio waves, and the reading device can obtain necessary information.

  Since the non-contact IC tag 4 is completely contained in the arc-shaped slit 3 engraved in the end thick portion 2 of the paper tube main body 1, the mounting position is difficult to understand. The thick portion 2 is provided with a display portion 9 such as a mark symbol or coloring indicating the color. If printing ink is used as the display portion 9 for the mark symbol or coloring, the paper layer of the portion is humidified and swells, and the gap between the slit 3 and the IC tag 4 becomes narrower and is more firmly sandwiched. Is. In addition, in place of printing ink, the upper surface of the IC tag 4 may be engraved from the direction orthogonal to the IC tag 4.

  If the use state of the embodiment of the present invention configured as described above is described together with the operational effects, the IC tag 4 is inserted into the arc-shaped slit 3 carved in the end thick portion 2 of the paper tube main body 1. As a result, a paper tube with an IC tag is obtained.

  At that time, the IC tag 4 is inserted into an arc-shaped slit 3 engraved in the thick end portion 2 of the paper tube main body 1, and the slit 3 is engraved by an arc-shaped blade and is made of paper. The entanglement of the fibers in the layer is disturbed to increase the frictional resistance, and the IC tag 4 does not come out of the slit 3 due to the elasticity retention of the paper layer.

  Further, since the IC tag 4 is attached to the end thick portion 2 of the paper tube main body 1, there is no fear of being damaged like an IC tag attached to a conventional paper tube inner cylinder, and the IC is inserted. Since the tag 4 is formed in an arc shape, a radio wave transmission / reception range can be ensured. Further, since the IC tag has flexibility, it can be inserted into the arc-shaped slit 3 very easily. In addition, there will be no trouble at the time of winding the wound product and during transportation after winding.

(Example 1)
Specific examples of the present invention are shown below. The strip-shaped base paper was wound into a spiral in several layers to obtain a cylindrical paper tube body 1 having an outer diameter of 92φ, an inner diameter of 76φ, and a length of 100 mm. An arcuate blade having a thickness of 0.6 mm and a width of 70 mm is positioned approximately in the middle of the back wall portion 2 of the paper tube main body 1 so that the slit width is 0.15 mm, the slit length is 70 mm, and the slit depth is 10 mm. A circular slit 3 was formed. An IC tag 4 having a thickness of 0.05 mm, a length of 65 mm, and a height of 10 mm was inserted into the arc-shaped slit 3 and a circle-shaped display portion 9 was attached with a red printing ink to obtain a paper tube with a tag.

  When the paper tube body 1 with a tag is attached to a liquid crystal film having a thickness of 0.03 mm and a width of 100 mm with a thickness of 500 m, the information written in the memory part of the IC chip in advance is tested with a reading device. The radio wave transmission / reception between the IC tag and the reading device was good and could be read instantaneously.

Comparative example

(Comparative Example 1)
In the same paper tube main body as in Example 1 and the IC tag, the fixing position of the IC tag was fixed not to the end thick portion 2 of the paper tube main body 1 but to the upper end of the outer surface of the front portion with an adhesive. A liquid crystal film similar to that of the first embodiment was applied to the paper tube main body, and a test was conducted to determine whether the information previously written in the memory portion of the IC chip could be read by the reading device. Radio wave transmission between the device and the reader was good and could be read instantaneously, but because the IC tag is on the outer surface, it may be damaged during winding or transport, and there is a problem with durability I understood that.
(Comparative Example 2)

  With the same paper tube main body and IC tag as in Example 1 above, the IC tag was fixed to the upper end of the inner surface of the front portion of the paper tube main body 1 with an adhesive instead of the end thick portion 2 of the paper tube main body 1. A liquid crystal film similar to that of the first embodiment was applied to the paper tube main body, and a test was conducted to determine whether the information previously written in the memory portion of the IC chip could be read by the reading device. The radio wave transmission and reception between the camera and the reader was good, and reading was possible instantly. Since the IC tag is hidden on the inner surface, it will not be damaged as in Comparative Example 1. However, it is troublesome to attach the IC tag and takes time, and static electricity is generated due to friction with the spindle. It was found that the tag might malfunction.

  From the above, the present invention is superior in damage and durability compared to Comparative Example 1, and more easily compared to Comparative Example 2, and more reliable transmission and reception of radio waves between the reading device and the IC tag than in Comparative Example 2. It was found to be excellent in performance.

  The main embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and various designs can be made within the scope that can achieve the object of the invention and do not depart from the gist of the invention. It goes without saying that changes are possible.

  INDUSTRIAL APPLICABILITY The present invention can be used as a paper tube around which various products such as film, carbon fiber, synthetic yarn, paper and thin sheet are wound.
