Description

The present invention relates to a packaging roll body in which a packaging band is wound around a core, and a method for manufacturing the same.

A packaging roll body for food packaging is used to preserve and dry food and to prevent the adhesion of foreign matter.As shown in FIG. 6, this packaging roll body 1 is equipped with a cylindrical core 2. A transparent band-shaped wrap film 10 is wound around the core 2 to a predetermined length, and after being wound, the wrap film 10 is inserted into a special packaging box and subjected to various inspections. The product is shipped (see Patent Documents 1 and 2).

The wrap film 10 is formed into a thin film using polyvinylidene chloride, etc., which has excellent stain resistance and moisture resistance, and is rewound from the original film onto the core 2 using a rewinder (winding machine). A slippery paper 11 is attached to the free end of the roll end of the wrap film 10 to make it easy to grasp the free end. The task of starting the initial withdrawal in step 10 becomes easier.

By the way, in recent years, from the perspective of emphasizing safety and quality improvement, the packaging roll body 1 has been designed to have traceability that clarifies ``when, where, and by whom the packaging roll body was manufactured.'' is required. In response to this request, methods have been developed and proposed in which the device number of the rewinder is stamped on the surface of the pick-up paper 11 and the date and time of packaging is stamped on the surface of the packaging box.

JP 2019-163063 Publication Japanese Patent Application Publication No. 2002-284259

The conventional packaging roll body 1 is constructed as described above, and methods have been proposed in which the device number of the rewinder is engraved on the surface of the pick-up paper 11 or the packaging date and time is engraved on the surface of the packaging box. Even if traceability can be ensured to some extent, it may not be possible to ensure the necessary and sufficient traceability.

To explain this point in detail, for example, when manufacturing the packaging roll body 1, a plurality of rewinders are used to rewind the wrap film 10, and a cartoner (boxing machine) that inserts the packaging roll body 1 into packaging boxes and packs them is used. When one unit is used, multiple packaging rolls 1 rewinded by multiple rewinders are combined and mixed together before packaging, so if a quality problem occurs with the packaging roll 1, the original Otherwise, it will be difficult to identify the rewinder that rewinded the wrap film 10. In addition, since the pick-up paper 11 is removed and discarded after the initial pull-out operation of the wrap film 10 is started, even if the rewinder device number is engraved, the rewinder paper 11 that rewinds the original film or the wrap film 10 It becomes extremely difficult to identify.

Further, even if the packaging roll body 1 is determined to be defective due to a defective appearance of the packaging box in which it was packed, if it is determined to be a good product in the re-inspection process, it is reinserted into a new packaging box and packed. However, at this time, there will be a lag in manufacturing time between the new packaging box and the new packaging box. In this case, even if the packaging date and time are stamped on the surface of a new packaging box, it is not the manufacturing date and time of the packaging roll 1, so if a quality problem occurs with the packaging roll 1, the packaging roll 1 can be traced back. It is not easy to identify the

It is an explanatory view showing typically a 2nd embodiment of a packaging roll body concerning the present invention. FIG. 3 is a perspective explanatory view schematically showing a third embodiment of a packaging roll body according to the present invention. It is an explanatory view showing typically a 3rd embodiment of a packaging roll body concerning the present invention. It is a perspective explanatory view showing a conventional packaging roll body.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.A packaging roll body 1 in this embodiment has a wrap film 10 for food packaging on a core 2, as shown in FIGS. 1 and 2. Both ends of the core 2 are made to protrude from the wrap film 10 so as to be visible, and predetermined product history information 20 is printed on the circumferential surface of at least one of the two protruding ends of the core 2. By doing so, in the event that a quality problem occurs, it is possible to trace the product back to the manufacturing stage (traceability) and quickly investigate the cause.

The winding core 2 is made into a long, cylindrical, inexpensive paper tube 3 that is excellent in dust resistance, surface smoothness, etc. by spirally wrapping recycled paper, for example, and a large number of books are stored in a hopper of a rewinder (not shown). and sequentially retrieved. Predetermined product history information 20 is printed on the outer peripheral surface of at least one end 5 of both ends 4 of this paper tube 3.

The wrap film 10 is formed into a long transparent band shape using a predetermined resin, and is rewound from a thick original film to the outer circumferential surface of the paper tube 3 other than both ends 4 using a rewinder. The wrap film 10 is made of polyvinylidene chloride, polyvinyl chloride, polyethylene, etc., which have excellent stain resistance and moisture resistance, and is formed into a flexible thin film with a thickness of 5 μm or more and 12 μm or less, and is rolled flat around the outer peripheral surface of the paper tube 3. It can be wrapped in multiple layers using this method.

The size of the wrap film 10 is set to approximately 45 cm x 50 m, 45 cm x 55 m, 45 cm x 100 m, 30 cm x 30 m, 30 cm x 100 m, 30 cm x 110 m, or 22 cm x 100 m so as not to stretch excessively. In addition, near the center of the free end of the wrap film 10 on the outermost periphery, a strip-shaped pick-up paper 11 is attached after rewinding to make it easier to grasp the free end. By pinching and pulling 11, it becomes very easy to start pulling out the wrap film 10 from the packaging box for the first time.

In such a packaging roll body 1, after a predetermined length of wrap film 10 is re-wound from a thick roll onto a paper tube 3 by a rewinder, and a pick-up paper 11 is attached, it is transported from the rewinder to a downstream (not shown). The product is transported by a conveyor to a cartoner, which inserts the product into a long and narrow hollow packaging box from the open end and packs it into the product.The product is then subjected to visual inspection using a visual sensor to form the final product.

The packaging roll body 1 is inserted into the packaging box so that the wrap film 10 on the inner surface of the roll faces downward when the wrap film 10 is pulled out from the packaging box. Further, the appearance inspection can also be used to confirm the printed portion of the paper tube 3 and to inspect the direction in which the wrap film 10 is pulled out.

The predetermined product history information 20 includes, for example, original fabric information expressed by various characters, symbols, colors, combinations of these, etc., lot, rewinder device number, manufacturing date and time of the packaging roll body 1, etc. is printed in a small and visible manner in the circumferential direction of the outer peripheral surface of one end portion 5. To print this predetermined product history information 20, an industrial inkjet printer 21 is used, which prints in a non-contact manner by directly jetting particulate ink (see the arrow in FIG. 1) 22 from a print head onto the outer peripheral surface of the paper tube 3. , a thermal inkjet printer, a laser marker, etc. are selectively used, and these are appropriately installed near the discharge section of the rewinder or in the space between the discharge section of the rewinder and the cartoner.

Among these printing devices, the inkjet printer 21 for lowercase letters, which can directly print at high speed even on the curved and narrow outer peripheral surface of the easily deformable paper tube 3, is optimal. Examples of the inkjet printer 21 include, but are not limited to, KGKJET CCS3000L [manufactured by Kishu Giken Kogyo Co., Ltd.: product name], Lynx 8900 [manufactured by Almark Co., Ltd.: product name], and the like.

When the inkjet printer 21 is employed, the ink 22 of the inkjet printer 21 is preferably a visible edible ink made from only food additives permitted by the Food Sanitation Act. Specific examples of this edible ink include, but are not limited to, CN7 Black [manufactured by Kishu Giken Kogyo Co., Ltd.: product name].

In the above configuration, when manufacturing the packaging roll body 1, a predetermined length of the wrap film 10 is re-wound around the paper tube 3 of the rewinder, and the inkjet printer 21 is operated to remove the paper tube 3 exposed from the wrap film 10. The packaging roll body 1 can be manufactured by printing predetermined product history information 20 from above on the outer circumferential surface of the one end portion 5 with high precision and attaching the pick-up paper 11. At this time, the amount of ink in the inkjet printer 21 is set to the minimum from the viewpoint of preventing deformation of the paper tube 3 due to application of the ink 22. The manufactured packaging roll body 1 is conveyed from a rewinder to a downstream cartoner, where it is inserted into a special packaging box and packed, and then subjected to an external inspection and the like, and non-defective products are shipped.

According to the above configuration, the predetermined product history information 20 is printed on the outer circumferential surface of one end 5 of the paper tube 3 that is used until the wrap film 10 is used up, so that the packaging roll 1 can be printed with "when, where, and by whom it was manufactured." It is possible to ensure necessary and sufficient traceability. To explain this effect in detail, for example, when manufacturing the packaging roll body 1, a plurality of rewinders are used to rewind the wrap film 10, and one cartoner is used to insert the packaging roll body 1 into a packaging box and package it. In this case, even if a plurality of packaging roll bodies 1 rewinded by a plurality of rewinders merge and mix together before packaging, if the predetermined product history information 20 of the paper tube 3 is utilized, the original rolls and the rewinder can be This can effectively prevent interference with identification.

Furthermore, even if the pick-up paper 11 is removed and discarded after the initial pulling-out operation of the wrap film 10 is started, the original fabric and the rewinder can be easily identified from the predetermined product history information 20 of the paper tube 3, and the packaging roll body 11 can be easily identified. quality issues can be addressed. In addition, when the packaging roll 1 determined to be good in the re-inspection process is reinserted into a new packaging box and packed, the packaging roll 1 can be retrospectively identified and any quality problems with the packaging roll 1 can be resolved. It becomes possible to deal with it. Furthermore, since the predetermined product history information 20 is printed on the outer peripheral surface of the one end 5 of the paper tube 3 by the inkjet printer 21, it becomes possible to print the information in a short time and at low cost.

Next, FIG. 3 shows a second embodiment of the present invention. In this case, a predetermined area is formed in the circumferential direction of the outer peripheral surface of both exposed ends 4 of the paper tube 3 on which the wrap film 10 is re-wound. Product history information 20 is printed respectively.

The predetermined product history information 20 may have the same content at both ends 4 of the paper tube 3, or may have different content. The other parts are the same as those in the above embodiment, so the explanation will be omitted.
In this embodiment, the same effects as in the above embodiment can be expected, and since the predetermined product history information 20 is printed on both ends 4 of the paper tube 3, the amount of the predetermined product history information 20 can be increased. It is clear that there is hope. Furthermore, even if the predetermined product history information 20 on one end 5 of the paper tube 3 is incorrectly printed, if the predetermined product history information 20 on the other end of the paper tube 3 is used, the packaging roll body 1 can be Necessary and sufficient traceability can be ensured.

Next, FIGS. 4 and 5 show a third embodiment of the present invention. In this case, in the circumferential direction of the outer peripheral surface of at least one end 5 of both exposed ends 4 of the paper tube 3, The predetermined product history information 20 is hidden and printed using invisible ink by an inkjet printer 21 to make the predetermined product history information 20 invisible.

The invisible ink is a stealth ink that complies with the Food Sanitation Act and standards for foods, additives, etc. (Ministry of Health and Welfare Notification No. 370 of 1950), and preferably emits blue light when irradiated with a black light or the like. Specific examples of this invisible ink include, but are not limited to, CN-324 fluorescent [manufactured by Kishu Giken Kogyo Co., Ltd.: product name].
Although the predetermined product history information 20 is originally invisible, it is illustrated by dotted lines in FIGS. 4 and 5 for convenience of explanation. The other parts are the same as those in the above embodiment, so the explanation will be omitted.

This embodiment can also be expected to have the same effects as the above-mentioned embodiments, and since the predetermined printed product history information 20 cannot be grasped with the naked eye or a camera, the predetermined product history information 20 can be used by consumers other than those involved. It is clear that this can be effectively prevented from being grasped and recognized by others. Furthermore, even if the characters forming the predetermined product history information 20 are unclear and unsightly, the predetermined product history information 20 will not be visible to the eye or camera, so it is possible to prevent deterioration of the aesthetics of the packaging. The design of the roll body 1 and the paper tube 3 can be maintained.

In the above embodiment, the wrap film 10 for food packaging is wrapped around the core 2, but the present invention is not limited to this. You may also re-wrap the aluminum foil from the original film. Further, in the above embodiment, the predetermined product history information 20 is printed on the circumferential surface of at least one end of the core 2 by the inkjet printer 21, but the present invention is not limited thereto.

For example, if necessary, it may be possible to print with a CO ₂ laser, a fiber laser, or a UV laser so that it can be traced up to the manufacturing stage of the packaging roll body 1. If possible, the packaging roll body 1 is manufactured by printing predetermined product history information 20 on the inner peripheral surface of at least one end of the core 2 using an inkjet printer 21, a CO ₂ laser, a fiber laser, or a UV laser. It may also be possible to trace the information down to the stage. Furthermore, before inserting the manufactured packaging roll body 1 into a packaging box and packaging it, the appearance of the packaging roll body 1 is imaged by a visual sensor, the printing position including predetermined product history information 20 is inspected, and the wrap film 10 is inspected. The directions may be aligned.

The packaging roll body and the manufacturing method thereof according to the present invention are used in the field of manufacturing belts made of resin films, resin sheets, and aluminum foils.
