Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stamping device for imprinting on the surface of an article, and in particular, a stencil printing plate having a surface of an impregnated body impregnated with ink covered with a stencil sheet is inserted into a plate making device. The present invention relates to a stamping device in which a stencil sheet is heated and punched by a heating device to form a stamp face portion.

[0002]

2. Description of the Related Art Recently, a stencil printing plate in which the surface of an impregnated body impregnated with ink is covered with a stencil sheet is fed into a plate making apparatus, and a thermal head provided in the plate making apparatus heats and punches the stencil sheet. A stamp surface portion is formed, and the master plate for stencil printing on which the stamp surface portion is formed is taken out from the plate making device and attached to a stamp block having a handle, and the stamp block is used to stamp the stamped master plate on the surface of the article. Stamping devices for stamping characters or figures have emerged. In such a stamping device, the thermal printing head is pressed against the stencil sheet to heat and punch the stencil printing plate while transporting the stencil printing plate at a constant speed in the plate making device.

[0003]

However, when the master plate for stencil printing is carried in the plate making apparatus, a plurality of positions of the master plate for stencil printing are held by the carrying rollers for carrying. At the time of punching, the stencil printing plate comes into contact with another conveyance roller, and when the original plate comes into contact with another conveyance roller, the stencil printing plate is slightly misaligned and conveyed, so that the punching is performed. There is a problem in that a pitch shift occurs.

Further, since there is no stopper for opening and closing the conveying path in the plate making device, there is a problem that it is difficult to know how much the original plate should be inserted when it is inserted in the plate making device.

In view of the above points, the present invention has an object to provide a stamping device which does not cause a deviation of the punching pitch when the stencil printing plate is fed into the plate making device to punch the plate.

[0006]

Therefore, the present invention is directed to a stencil printing plate in which the surface of an impregnated body impregnated with ink is covered with a stencil sheet, and the stencil sheet is conveyed by a conveying device while the stencil sheet is conveyed by the conveying device. In a stamping device configured to heat and punch a raw paper by a heating device to form a printing surface portion, the heating device holds the heating device so as to move between a punching position in contact with the stencil raw paper and a standby position separated from the punching position. A roller holding member provided on the same member with a holding member, a conveying roller that interlocks with the operation of the holding member and that conveys the original plate inserted in the plate making apparatus, and a discharge roller that discharges the original plate after the completion of plate making. And a stopper member that operates in conjunction with this roller holding member to stop the original plate inserted into the plate making apparatus and open the transport path when the original plate is transported by the transport device. It was constructed in obtaining way.

[0007]

When the stencil printing plate is inserted into the plate making apparatus, the leading end of the stencil printing plate comes into contact with the stopper member and stops. After that, the heating device holding member swings, and the heating device such as a thermal head held thereby comes into contact with the stencil sheet of the stencil printing plate. Along with the swinging of the heating device holding member, the roller holding member holding the carrying roller is swung, and the carrying roller comes into contact with the stencil printing original plate to complete the carrying preparation and the stopper member. Escapes from the transport path. The heating operation of the heating device is started at the same time as the start of the transportation by the transportation roller, and after the heating operation is completed and the perforation of the stencil sheet is completed, the leading end portion of the stencil printing plate comes into contact with the discharge roller. The stencil printing plate is discharged by the discharge roller. In this way, at the time of punching, only the transport roller contacts the stencil printing plate, the discharge roller contacts the stencil printing plate after punching, and the transport roller and the discharge roller simultaneously contact the stencil printing plate during punching. Therefore, it is possible to prevent the deviation of the drilling pitch during drilling.

Further, a lower guide plate 91 is provided at a position facing the upper guide plate 90 so as not to interfere with the movement of the discharge roller 23.

Next, the operation of the stamp device of the present invention will be described. 2 and FIG. 5 to FIG. 8, FIG. 2 shows a state in which the stencil printing plate 50A is inserted to a predetermined position in the plate making apparatus 1, and the insertion tip thereof is the stop frame 8
It contacts the stop plate portion 25b of 0 and is stopped. At this time, the upper conveying roller 13a is moved to the stencil printing plate 50.
The platen 12 is in contact with the left and right rails 62 of A, and is in contact with the upper surface of the frame 61 between the left and right rails 62, 62. Next, when the plate making key 4 is pressed and the apparatus starts to operate, the thermal head holding plate 16 is rotated clockwise by a cam mechanism (not shown) so that the thermal head 15 causes the heat sensitive stencil plate of the stencil printing plate 50A. It contacts the base paper 74. The clockwise rotation of the thermal head holding plate 16 releases the bias of the roller holding plate 19 in the clockwise direction, so that the roller holding plate 19 is moved counterclockwise in the figure by the right and left of the tension springs 24. The lower transport roller 13b is rotated to bring it into contact with the lower surface of the rail 62 of the stencil printing plate 50A. When the roller holding plate 19 rotates in the counterclockwise direction about the pivot 21, the operating pin 22 rotates in the counterclockwise direction, and the operating pin 22 rotates the stop frame 80 in the clockwise direction about the pivot 26. And the stop plate 25b swings downward to open the conveyance path. In this state, the transport start state of the stencil printing plate 50A is completed. From the state shown in FIG. 5 when the upper conveying roller 13a is driven, the master plate 50A for stencil printing is shown on the left side of the drawing.

3b conveys the stencil printing plate 50A to the left as a pair of transport rollers, and at this time, the discharge roller 23 is not in contact with the stencil printing plate 50A. When the stencil printing plate 50A is conveyed to the left side and the punching operation is completed and proceeds about 2 mm, the thermal head holding plate 16 swings counterclockwise by a cam mechanism (not shown) as shown in FIG. Along with this, the roller holding plate 19 swings counterclockwise. By the seesaw motion of the roller holding plate 19, the discharge roller 23 comes into contact with the left and right rails 62, 62 of the stencil printing plate 50 and starts the discharge operation. In the state shown in FIG. 7, since the contact plate 25c of the stop frame 80 is in contact with the rail 62 of the stencil printing plate 50A, the stop frame 80 does not swing further counterclockwise. However, as shown in FIG. 8, when the master plate 50A for stencil printing passes above the contact plate 25c in the middle of the discharging operation, the stop frame 80 swings counterclockwise in the figure to a position where it blocks the conveying path. At this time, the contact plate 25c
Contacts the upper guide plate 90 to position the stop frame 80. After piercing, stencil printing plate 50A
The sheet is conveyed leftward in the figure by the discharging operation of the discharging roller 23, and is discharged to the lower surface of the stamp block housing section 7.
Thereafter, the stamp block 60 is attached to the stencil printing plate 50.
