DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape such as an industrial pressure-sensitive adhesive tape, a tape lot display method and a tape lot display forming apparatus.

[0002]

2. Description of the Related Art Tapes such as industrial adhesive tapes are shown in FIG.
As shown in FIG. 8, after the adhesive is applied to the base material and wound up as a long roll (about 3000 m) and a wide web roll 20, a paper core or the like supplied by a transfer means such as a conveyor 6 is used. A small roll (about 50 m) is wound around the core 23 to form a small roll 21, and the small roll 21 is cut into a small width to form a product 25.

[0003]

Incidentally, when a complaint occurs in a product, it may be necessary to determine the lot of the film or the like which is the base material of the tape as a measure against the complaint.

[0004] However, a lot of a film or the like serving as a base material of a tape can be discriminated at the stage of the raw material roll 20, but is wound into a small roll and cut into a small width size to obtain a product 25, and a product of a different lot. When 25 are mixed and returned as a claim, it cannot be determined which lot of film is used as a base material. Therefore, the lot of the film or the like, which is the base material of the tape, cannot be determined, and an appropriate countermeasure may not be taken.

SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide a tape and a tape lot display method capable of immediately discriminating a tape lot when a problem such as a complaint occurs.

[0006] A tape, a tape lot display method and a tape lot display method, which can automatically and continuously form a needle hole display on the outer peripheral surface of a winding core so that a tape lot can be immediately identified. It is an object to provide a forming device.

[0007]

A tape according to the present invention is characterized in that a needle hole is formed on the outer peripheral surface of a core for winding the tape body around the outer peripheral surface.

[0008] The method for displaying a lot of a tape according to the present invention comprises:
The present invention is characterized in that the lot of the tape is displayed by forming a needle hole display on the outer peripheral surface of the core. In addition, the tape lot display forming apparatus of the present invention includes a conveyor for transferring a core, a cylinder disposed above the conveyor, and a needle rotatably attached to a tip of a rod of the cylinder. And a needle hole forming device.

A paper tube or the like can be suitably used as the core. The size of the needle hole display formed on the outer peripheral surface of the core is about 0.01 mm in hole diameter and about 0.3 mm in depth. However, it is desirable because the needle hole indication cannot be seen from the top of the product. Needle hole display, for example, one line in the axial direction of the winding core,
It can be performed by providing two rows or a plurality of rows. As a result, it is possible to discriminate between the needle hole indications or the core in which the needle hole indication is not displayed. The pitch of the formed needle hole indications is desirably about 10 mm so that at least one needle hole indication is formed on the core of a product cut into a small width.

[0010] It is also desirable that the pressure of the cylinder can be adjusted. If the pressure is adjustable, the needle hole indication can be formed on the tape core at an appropriate pressure.

[0011]

According to the present invention, the tape lot is discriminated and displayed on the core by displaying the needle hole formed on the outer peripheral surface.

[0012] Further, while the core is being transferred by the transfer conveyor, the outer periphery is formed by a needle provided on a needle hole forming tool rotatably attached to a tip of a rod of a cylinder disposed above the transfer conveyor. Since the lot number is displayed on the surface, the lot number is automatically and continuously formed on the core.

[0013]

Embodiments will be described below with reference to the drawings. FIG. 1 is a sectional view of an example of the tape of the present invention. FIG. 2 is a plan view of a core used for the tape of FIG. 1, and FIG. 3 is a partial cross-sectional view of a main part S of FIG.

Reference numeral 1 denotes a tape of the present invention, in which a tape body 11 is wound around a core 12. A paper tube is used for the core 12. Reference numeral 2 denotes a needle hole indication formed on the outer peripheral surface of the core 12, and the needle hole indications 2 having a diameter D of 0.01 mm and a depth H of 0.3 mm are formed in a line at an interval of a pitch P10 mm in the axial direction.

FIG. 4 is a plan view of a core in one example of the tape lot display method of the present invention. Reference numeral 3 denotes a core for the formed tape A lot in which the needle hole indicators 2 are arranged in one row in the axial direction, and reference numeral 4 denotes a core for the formed tape B lot in which the needle hole indicators 2 are formed in two rows in the axial direction. Reference numerals 5 and 5 denote cores for the tape C lot in which the needle hole indication is not formed. The needle hole indications 2 are formed at intervals of a pitch P10 mm in the axial direction. Needle hole display 2 is 1
Since the cores 3 and 4 are formed into a product by cutting the cores 3 and 4 into small widths, at least one needle hole indication 2 is formed on the cores 3 and 4 of the product. . Therefore, the cores 3, 4, and 5 can be determined from the needle hole display 2. Therefore, the discrimination of the film or the like as the base material of the pressure-sensitive adhesive tape wound on the cores 3, 4, 55 can be easily and visually confirmed even when the product is mixed and returned as a claim.

FIG. 5 is a front view of an embodiment of a tape lot display forming apparatus according to the present invention, and FIG. 6 is a side view thereof. The tape lot display forming apparatus 10 includes a conveyor 6 for transporting the core 1, a cylinder 8 disposed above the conveyor, and a needle rotatably attached to a tip of a rod 81 of the cylinder 8. And a needle hole forming tool 7 provided with a needle 71. Reference numeral 31 denotes a mount on which the cylinder 8 is mounted, and reference numeral 32 denotes a regulating plate that regulates the lateral movement of the core 12.

The needle 71 of the needle hole forming tool 7 has a round blade shape, and is spaced at an equal pitch P (10 mm) on the outer peripheral surface.
It is attached to the needle hole forming tool 7 by well-known fixing means. The flow path of the cylinder 8 can be switched by a switching valve 82. The rod 81 of the cylinder 8 can be moved up and down in the direction of the arrow Y perpendicular to the winding core 12 by this switching.

Next, a method for forming a lot indication of a tape according to the present invention will be described. First, the rod 81 of the cylinder 8 is lowered to position the needle hole forming tool 7 at a predetermined position. Next, the conveyor 6 is driven, the core 12 is placed on the conveyor 6, and the core 12 is transferred in the direction of the arrow X. When the core 12 is moved in the direction of the arrow X, the core 12 comes into contact with the needle hole forming tool 7 and the core 71 is provided by the needle 71 provided in the needle hole forming tool 7.
A needle hole display 2 for displaying a lot is formed on the outer peripheral surface of the needle 2. Further, since the lateral movement of the core 12 is regulated by the regulating plate 32, a predetermined needle hole indication 2 is formed at a predetermined position on the outer peripheral surface of the core 12.

[0019]

According to the present invention, the lot of the tape is discriminated and displayed on the core by the indication of the needle hole formed on the outer peripheral surface. Therefore, when a problem such as a complaint occurs, the lot in which the complaint occurred is immediately discriminated. And appropriate countermeasures can be taken.

Further, since the needle hole indication formed on the outer peripheral surface is a needle hole having a very small diameter, the appearance is not impaired even with a transparent tape. Further, while the core is being transferred by the transfer conveyor, a lot is formed on the outer peripheral surface by a needle provided in a needle hole forming tool rotatably attached to a tip of a rod of a cylinder disposed above the transfer conveyor. , The lot display can be automatically and continuously formed on the winding core.
