DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tubular or rod-shaped work provided with a bar code for displaying product information and the like, and a method of manufacturing the same.

[0002]

2. Description of the Related Art When a tube or bar having a considerable length is cut into a predetermined length to produce a product, the following method has been used to provide a bar code on each product.

First, there is a method in which a label or the like on which a bar code is written is affixed to each product after cutting.

There is also a method in which a plurality of barcodes are provided at predetermined intervals on a pipe / rod before cutting into products, and the products are cut at predetermined positions so that the barcodes are inserted into each product.

[0005]

In the method of attaching a bar code label to each product after cutting, it is necessary to attach a label to a predetermined position of each product accurately. This is because, when the bar code is automatically read in a state where the product is set in the machine, if the sticking position is shifted, the reading becomes impossible. However, there is a problem in that a lot of cost is required to attach labels one by one to accurate positions.

According to a method of providing a plurality of barcodes at predetermined intervals on a tubular material or the like as a raw material and separating the barcodes at predetermined positions, there is a problem that high printing position accuracy and cutting accuracy are required. In addition, raw materials 1
We would like to get as many books as possible, but the yield will drop due to the accumulation of errors.

Further, Japanese Utility Model Laid-Open No. Hei 3-3068 describes a method of providing a ring-shaped bar code on a tube / rod. However, when a step of separating a product from a raw material is used, this method has the same problems as the above two methods, and furthermore, when a bar code is pasted in a ring shape or printed, a If the seam is discontinuous, an error will occur when this part is scanned.

According to the present invention, when a plurality of products are cut out of a tube or rod as a raw material, a work provided with a bar code having no restriction on a cutting position, a detection position after the cutting, and the like. It is intended to provide a manufacturing method.

[0009]

According to a first aspect of the present invention, there is provided a workpiece having a tubular shape in which a bar code composed of a plurality of lines parallel to each other is spirally provided continuously from one end to the other end on its own peripheral surface. It is a bar-shaped work.

According to a second aspect of the present invention, there is provided a workpiece comprising a bar-like body formed of a plurality of parallel lines formed with a bar code.
It is a tubular or rod-shaped work which is provided spirally from one end to the other end without interruption.

The work described in claim 3 is a tubular or rod-shaped work in which a bar code composed of a plurality of lines parallel to each other is spirally provided continuously from one end to the other end on its own inner peripheral surface. .

According to a fourth aspect of the present invention, there is provided a workpiece comprising a bar-shaped body formed of a plurality of lines parallel to each other.
It is a tubular or rod-shaped work provided spirally from one end to the other end without any break on its inner peripheral surface.

According to a fifth aspect of the present invention, in a method of manufacturing a work, a bar code composed of a plurality of lines parallel to each other is spirally provided continuously from one end to the other end on the peripheral surface of a tubular or rod-shaped work. Thereafter, the work is cut at a predetermined interval.

[0014]

The same bar code appears on the product obtained by cutting at any position in the longitudinal direction.

The spiral bar code with respect to the center axis of the work can be detected by relatively moving the work and the sensor in the circumferential direction of the work, or by moving the sensor relative to the center axis of the work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a belt-like material 1a wound in a cylindrical shape.
On its surface, a bar code 2 composed of a plurality of lines parallel to each other along the longitudinal direction of the band is continuously printed.

FIG. 2 shows an example in which the strip 1a is spirally wound around an outer peripheral surface of a tubular body 4 which is a paper work, with respect to a central axis of the tubular body 4a.

The tubular body 4 can be used as a container, a core for winding a cord-like material, or a core for winding a sheet-like material such as paper or cloth. In order to manufacture a roll in which such a string or a sheet is wound, a long tubular body having a spiral barcode 2 as described above is prepared, and after winding the string or sheet, What is necessary is just to cut | disconnect to predetermined length, or to wind the said string etc. around the cut tubular body. Since the spiral bar code 2 is provided endlessly from one end to the other end of the tubular body 4, the same bar code 2 is provided on the core of each roll which is a product no matter where it is cut.
Appears. That is, high accuracy is not required for the position to be cut.

Each of the figures shown in the figures is an example in which the present invention is applied to a stencil sheet. When such a roll-shaped stencil sheet having a bar code 2 is provided in an automatic stencil printing apparatus, for example, as shown in FIG. As described above, a part of the tubular body 4 serving as the core may be exposed from the end face of the roll, and the outer peripheral surface thereof may be read by the sensor 5 to obtain the product information of the stencil paper as the product. A high precision is not required for the installation position of the sensor 5, and if the roll makes one rotation with respect to the fixed sensor 5, it is possible to reliably read the seamless one-cycle bar code 2.

FIG. 4 shows an example in which the same band 1b as in FIG. 1 is used as wrapping paper such as roll paper. When the belt-like material 1b is spirally wound around the outer peripheral surface of the roll paper, the barcode 2 having the same configuration as the tubular body 4 shown in FIG. 2 is obtained. In addition, the name 3 of the manufacturer or the like can be printed on the surface of the strip 1a. If the barcode 2 is optically readable, the printing of the company name 3 or the like may be performed with ink of a color that cannot be read by the optical sensor.

FIGS. 5 and 6 show a tubular body 4a which is the core of the roll-shaped stencil paper. The tubular body 4a has the strip 1a spirally attached to the inner peripheral surface thereof, and the bar code 2 is provided inside the tubular body 4.

When a roll of stencil paper having such a tubular body 4a as a core is provided in an automatic stencil printing apparatus, as shown in FIGS. 5 and 6, the roll (tubular body 4a) is attached to a holder 6a.
And is rotatably supported by a beam frame (not shown). The sensor 7 inserted through the center hole 6a of the holder 6 detects the bar code 2 on the inner peripheral surface of the tubular body 4a. Also in this case, similarly to the case of FIG. 3, the bar code 2 appears at any position on the inner peripheral surface, so that the position of the sensor 7 does not need to be high precision. 7
Can reliably read the bar code 2.

FIG. 7 shows a case where a spiral bar code 2 is provided endlessly on the outer peripheral surface of a cylindrical body 8 as a work.

As can be seen from the embodiments described above,
According to the present invention, it is possible to adopt a configuration in which a helical bar code is continuously provided on the inner and outer peripheral surfaces of a cylindrical body or the outer peripheral surface of a columnar body.

With such a configuration, the same bar code appears on the product obtained by cutting the workpiece at any position in the longitudinal direction. Further, since the barcode of the obtained product is provided on the entire peripheral surface of the product, a high positional accuracy is not required for the installation position of the sensor for reading.

Further, if a length in which a bar code of one cycle or more appears in the center axis direction can be ensured, the relative movement direction of the sensor may be the axial direction as shown in FIG. Good.

As shown in FIG. 9, a plurality of continuous bar codes 2 (2a) are provided on the peripheral surface of the work.
# 2b) or a plurality of sets (2a = 2b).

In each of the embodiments described above, a bar code composed of optically recognizable lines has been described. Further, in the above-described embodiment, the tubular body or the cylindrical body has a circular cross section orthogonal to the central axis, but as shown in FIG. As long as they do not deviate, even if the cross-sectional shape is polygonal or deformed, the same operation and effect as those of the above-described embodiment are obtained.

[0029]

According to the workpiece provided with the barcode of the present invention and the method for manufacturing the same, when a plurality of products are produced by cutting the raw material such as pipes, rods, and strips, the cutting position and the position after cutting are obtained. A large degree of freedom can be obtained for the detection position and the like.
