In the case of this embodiment, the carbon black C1 and the carbon red C2, which are necessary for printing, are transferred to the second film 200. The print heads 410 and 420 are separated from the platen rollers 112 and 122 except when thermal transfer is performed, and the print heads 410 and 420 are separated from the platen rollers 112 and 122.

0 and 120 do not move. The motor control unit 310, the print control unit black 411, and the print control unit red 421 are connected to the printing press control device 300 that controls the printing press.

The moving roller 221 is movable in a direction in which the corrugated cardboard A comes in and out of contact with the corrugated cardboard A.
Cardboard A when printing with 10, 420
It moves in a direction away from and stores a portion having a print pattern. Furthermore, the moving roller 221
Moves to the corrugated board A side when printing the print pattern on the corrugated board A, and discharges the second film 200 to the second take-up reel 213 side.

A thermal transfer roller (thermal transfer means) 500 is provided between the fifth guide roller 216 and the second guide roller 212. This thermal transfer roller 50
0 is driven so as to move along the longitudinal direction of the second film 200, and the second film 20
It is also driven so as to move in the direction of moving in and out of 0,
Each carbon C on the second film 200 is heated by pressing the second film 200 against the corrugated cardboard A and moving along the longitudinal direction of the second film 200.
The print pattern formed by C1 and C2 is thermally transferred to the corrugated board A.

Further, the thermal transfer roller 500 has a peripheral surface portion formed of a soft layer having a hardness of about 30 so that the second film 200 can be brought into close contact with an uneven printing surface such as the back surface of the corrugated cardboard A. You can do it. That is, it is possible to reliably print on a curved surface or a surface having irregularities.

Next, the operation of the printing machine configured as described above will be described.

When printing is started, a command signal of a predetermined print pattern is sent from the printing press controller 300 to each print controller 41.
1, 421 is output. The command signal of the printing pattern at this time is not a mirror-image inverted signal, but a corrugated cardboard A
It is the same as the print pattern for. Then, first, the print head black 410 moves to the platen roller black 112 side and presses the second film 200 against the first film black 110, and the heat generating resistor in the portion corresponding to the black of the print pattern generates heat. Then, the heat generated by the heating resistor is transferred to the first film black 110 through the second film 200, and the carbon black C1 is thermally transferred from the first film black 110 to the second film 200. When the portion of the print pattern corresponding to black is formed in this manner, the print head black 410 separates from the second film 200.

Then, the second film 200 moves,
The part of the print pattern on which black has already been formed moves to the position of the platen roller red 122. Then, the print head red 420 is moved to the platen roller red 122 side this time, and the second film 200 is moved to the first film red 120.
Then, the heating resistor in the portion corresponding to the red color of the print pattern generates heat. Then, the heat generated by the heating resistor passes through the second film 200 and the first film red 12
0, carbon red C2 is the first film red 12
Thermal transfer is performed from 0 to the second film 200.

The printing pattern of these carbons C1 and C2 is the same as that of the carbons C1 and C2 of the second film 200.
When viewed from the side on which C2 is attached, the printed pattern is a mirror image. Then, when the portions corresponding to black and red of the print pattern are formed, the print head red 420 separates from the second film 200.

In this way, the print pattern of the carbon black C1 and the carbon red C2 becomes the second film 200.
As it is formed on the upper side, the moving roller 221 moves in the direction away from the corrugated board A, and the portion having the print pattern of the second film 200 is accumulated. Also, each first
The film 110, 120 of each of the print heads 410, 4
It does not move except during thermal transfer at 20.

The print pattern is formed as described above, and while the print pattern is stored, the second film 2
00 is pulled out to the corrugated board A side by the second take-up reel 213, and the printing pattern reaches the printing position of the corrugated board A. Then, the winding by the second winding reel 213 is stopped, and the stopper member 700 moves to the fifth guide roller 216 side to move the second film 200 to the fifth side.
The guide roller 216. This allows the second
The film 200 is fixed at the portion of the fifth guide roller 216, and the second film 200 is in a state of being stretched uniformly between the fifth guide roller 216 and the second guide roller 212. Then, the heated thermal transfer roller 500 moves to the second film 200 side. Then, the thermal transfer roller 500 moves from the fifth guide roller 216 side to the second guide roller 212 side while pressing the second film 200 against the corrugated cardboard A. At this time, the printing pattern on the second film 200 is thermally transferred to the printing object such as the corrugated cardboard A by the heat generated from the thermal transfer roller 500. After the thermal transfer is completed, the thermal transfer roller 500 separates from the second film 200, and the second film 200 also separates from the corrugated board A.

When the printing on the corrugated board A is completed in this way, the printed corrugated board A is carried away by the belt conveyor B, and then a new corrugated board A is carried to the printing position. Then, printing on the cardboard A is repeated in the same manner as described above. Also, cardboard A
The printing pattern described above is formed during printing on the card, and during transportation and positioning of the corrugated board A, and the second film 200 having the printing pattern is moved by the moving roller 221.
Is stored by. That is, the formation and storage of the print pattern are always performed separately from the printing on the cardboard A. However, when the print pattern is stored faster than the print pattern is consumed by printing on the corrugated cardboard A, the print head black 410 and the print head red 420 are stored when the print pattern is stored in a predetermined amount. The formation of the print pattern by is stopped.

According to the printing machine configured as described above,
The print heads 410, 420 heat the first films 110, 120 from the second film 200 side to thermally transfer the carbons C1, C2 to the second film 200. Even when heated as in the case of printing on the corrugated board A at 420, it is possible to form a print pattern on the second film 200 which is mirror-inverted when viewed from the side where the carbons C1 and C2 are attached. By thermally transferring the printed pattern onto the corrugated cardboard A, it is possible to print a regular pattern on the corrugated cardboard A. Therefore, it is not necessary to invert and heat the print heads 410 and 420 in a mirror-image manner, so that the control of the print heads 410 and 420 becomes extremely simple. Moreover, since only the portion to be printed needs to be heated, the thermal transfer area by each print head 410, 420 is reduced, and the print pattern formation time can be shortened.
It is possible to reduce the consumption of heating energy required for forming a print pattern.

Further, the first film black 110 and the first film
By using the film red 120 of the above, a print pattern having black and red can be formed on the second film, and printing having black and red colors can be printed at once on the corrugated cardboard A. Therefore, multicolor printing by thermal transfer can be performed. Can be performed in an extremely short time and easily. Moreover, since the black / red color printing pattern is formed on the second film 200, two printing machines having black / red carbon are provided and the black / red color is printed twice on the corrugated cardboard A. Compared with the case of printing separately, it is possible to almost completely prevent color shift, and it is possible to perform extremely beautiful multicolor printing. Further, since it is not necessary to provide two printing machines having black and red carbon, it is possible to reduce the equipment cost.

Further, since the print pattern can be constantly formed and stored on the second film 200, the amount of print pattern formed in a unit time can be increased. Therefore, by increasing the moving speed of the thermal transfer roller 500 or the conveying speed of the corrugated board A, it is possible to increase the amount of consumption of the print pattern in a unit time. That is, the printing interval can be shortened.

Further, since the platen roller black 112 and the platen roller red 122 are provided at positions close to each other, the print patterns can be formed close to each other. Therefore, many print patterns can be stored. In addition, except at the time of thermal transfer, each first film 110,
Since 120 does not move, the carbon-containing film can be saved, which is economical.

24, that is, the platen roller black 112 and the platen roller red 122 are driven by the drive shaft black 610 and the drive shaft red 620 of the stepping motor, respectively, and the winding of the first winding motor is performed. Axis black 115
And the take-up shaft red 125 of the first take-up motor is driven by the torque motor, respectively, and the fourth guide roller 219 is simply idle. However, the components in these different points are
Since it is the same as the other example of the first embodiment (see FIG. 5) and the other example of the second embodiment (FIG. 6), description thereof will be omitted.

In each of the above-mentioned embodiments and other examples, the first film is constructed so as to be provided with two systems of black and red.
It goes without saying that the system may be provided alone, or a plurality of systems with other colors may be provided. However, it is necessary to provide a plurality of print heads corresponding to each first film.

Further, a plate-shaped corrugated cardboard A is to be printed.
However, it goes without saying that it may be a corrugated cardboard formed in a box shape, or may be formed of wood, iron, or another material. Moreover, the printed surface is not limited to a flat portion, but may be a curved printed surface such as the surface of a cylindrical can.

Further, the moving roller 221 is configured to be movable in the direction of separating from and contacting the corrugated cardboard A, but the moving roller 221 can be moved in any direction as long as it can temporarily store the second films 200 and 201. It may be configured to move.

Furthermore, in the first embodiment, the second embodiment and these other examples, the thermal transfer roller 500 is replaced by the fifth embodiment.
From the guide roller 216 side of the second guide roller 212
The thermal transfer roller 500 is configured to move from the fifth guide roller 216 side to the second side.
After moving to the guide roller 212 side, the moving direction is preferably changed alternately for each printing, such as moving from the second guide roller 212 side to the fifth guide roller 216 side.

[0068]

According to the present invention, while the portion of the print pattern of the second film is moved to the print symmetrical side, and while the print pattern is thermally transferred to the print target,
Since the print pattern can be formed on the second film, the amount of print pattern formed per unit time can be increased. Therefore, it is possible to increase the printing amount per unit time by increasing the thermal transfer speed by the thermal transfer means or increasing the transport speed of the printing object. That is, the printing interval can be shortened.
