2. Description of the Related Art Conventionally, crafts such as cards such as prepaid cards have been manufactured from a roll-shaped roll made of plastic resin or paper. In this case, create a roll of material such as plastic resin or paper, set it in the paper feed unit, unwind the material from the roll, print on the material, dry it, and then print it. It has been considered to produce crafts such as individual cards by subjecting the Jeji fabric to processing steps such as cutting and punching.

When printing is performed on a roll-shaped roll made of plastic resin or paper, it is usually necessary to print a plurality of times. In this case, a register mark is attached to one side of the original in advance, the register mark is detected by a detecting device, and printing is performed a plurality of times.

The printed material is wound up in the winding section, but the winding body in the normal winding state in the paper feeding section becomes the winding body in the reverse winding state in the winding section. When printing is further performed on the original fabric, the reverse-winding roll wound in the winding section is once rewound into the forward-winding roll, and then the original roll is unwound from the forward-winding roll. The register mark is detected and the further printing is performed.

In such a case, the register mark is detected and the next printing is performed on the material fed from the reverse winding-shaped roll without rewinding the reverse winding-type winding into the forward winding-type winding. If it can be applied, the printing process can be shortened and speeded up, which is convenient.

The present invention has been made in consideration of the above points, and is made of a plastic resin or paper that can perform printing with high accuracy on a material roll fed from either a normal winding or reverse winding state. An object of the present invention is to provide a roll-shaped original fabric printing device for manufacturing.

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 are views showing an embodiment of a roll-shaped original printing apparatus according to the present invention.

First, an outline of the entire printing apparatus will be described with reference to FIGS. 2 and 3. As shown in FIGS. 2 and 3, the printer 10 holds a roll of a roll-shaped roll 30 (see FIG. 1) made of plastic resin or paper, and feeds the roll from the roll. The unit 11 is provided. Paper feeder 1
The original fabric 30 fed from 1 has its registration mark 31.
After the detection unit 14 detects (see FIG. 1), the printer 12
The printing is carried out in and then dried by the dryer 13. After that, the original fabric 30 passes through the buffer 15 and the winding unit 2
Rolled up at 2.

The roll-shaped roll 30 made of plastic resin or paper is made of polyethylene terephthalate (P
ET), which is a raw material for crafts such as business cards and prepaid cards, and the register mark 31 is printed in advance. Further, crafts such as cards are printed at a predetermined position 32 of the original fabric 30.

Next, the detector 14 will be described in detail with reference to FIG. As shown in FIG.
A register mark 31 is provided in a direction orthogonal to the conveying direction (direction of arrow L), and a pair of detection devices 33 and 34 for detecting the register mark 31 are provided above both sides of the original fabric 30. The detection unit 14 has a pair of detection devices 33 and 34. The pair of detection devices 33 and 34 detect the registration mark 31 of the original sheet 30 fed from the winding body in either the normal winding or the reverse winding state, and detect the original sheet 30 in the transport direction (arrow L direction). Position the position in the conveyance direction. Next, one of the edges 30a of the original 30 is set to the edge 3
The position of the original 30 in the device width direction (arrow M direction) is detected by the detection sensor 1 provided below 0a. This positioning may be performed sequentially from either of the above directions. Further, the two directions may be simultaneously positioned. The register mark 31 is formed by making a hole in the original fabric 30 in the register mark forming unit 300 provided immediately before the detecting unit 14 (see FIGS. 2 and 3).

For example, in FIG. 1, the positioning in the conveying direction is performed by setting the original mark 30 at a predetermined position by detecting the register mark 31 by one of the detection devices 33 with respect to the original roll 30 fed from the roll in the normal winding state. It is designed to be positioned. Since the position of the register mark 31 is shifted to the left and right with respect to the original fabric 30 fed out from the reversely wound roll, the register mark 31 is detected by the other detection device 34 to position the original fabric 30 at a predetermined position. It is supposed to do.

Next, in the positioning in the width direction of the apparatus, one of the detection sensors 1 detects the original edge 30a of the original 30 fed from the roll in the normal winding state, and the original 30 is obtained.
Is positioned at a predetermined position. The position of the original fabric edge 30a is shifted to the left and right with respect to the original fabric 30 fed from the reversely wound roll, so the other detection sensor 2 detects the original fabric edge 30a to detect the original fabric 3
0 is positioned at a predetermined position. At this time, the positioning of the original fabric 30 is performed in order to perform printing.
The position of the original 30 is corrected so that the register mark 31 and the printed pattern of the original 30 are in predetermined positions, or the register mark 31 of the original 30 and the printed pattern of the original 30 are in predetermined positions. Then, the position of the print pattern is corrected, and the print pattern plate is corrected.

The term "normally wound / reversely wound state" means that, for example, when the winding body of the sheet feeding section 11 is in the normal winding state, the winding body wound by the winding section 22 is in the reverse winding state. Say that.

Next, the operation of this embodiment having such a configuration will be described. First, a roll of the roll-shaped original material 30 made of plastic resin or paper is set in the paper feeding unit 11. Next, the original 30 is unwound from the roll of the paper feeding unit 11, a hole is formed in the original as a register mark by the register mark forming unit 300, and the register mark and the original edge are detected by the detecting unit 14, and the original is detected. The counter 30 is positioned at a predetermined position. In this case, when the winding body of the paper feeding unit 11 is in the normal winding state,
The register mark 31 and the original edge 30a are detected by the one detection device 33 and the detection sensor 1 of the detection unit 14.

Next, the original fabric 30 is printed by the printing machine 12. Next, the original fabric 30 is dried in the dryer 13, passed through the buffer 15, and continuously wound in the winding unit 22.

When further printing is to be performed on the wound original sheet 30 wound in the reverse winding state on the winding section 22, the reverse winding original sheet 30 is set in the paper feeding section 11, Further printing is performed on the original fabric through the same steps as in. in this case,
In the detection unit 14, the register mark 31 and the original edge are detected by the other detection device 34 and the detection sensor 2.

As described above, according to this embodiment, the register mark 31 and the original edge can be accurately detected by the detecting section 14 in both the forward winding and reverse winding states. After the register mark 31 and the original edge are detected, the original sheet 30 is not rewound into the normal winding state.
Can be printed multiple times. Therefore, the printing process can be shortened and speeded up.

As the pair of detecting devices 33 and 34, a plurality of line sensors arranged in a direction (direction of arrow M) orthogonal to the transport direction L of the original fabric 30 may be used.

[0021]

As described above, according to the present invention,
It is possible to print with a printing machine and dry with a dryer after detecting the register mark on the original sheet fed from either the normal winding state or the reverse winding state. As described above, since it is possible to perform printing without rewinding the reversely wound roll into the forwardly wound roll, it is possible to shorten and speed up a plurality of printing steps.
