Description

[Detailed description of the invention] This invention is a date stamp installation method in a printing machine that allows date stamps to be inserted and supplied as needed into the grooves of a number of printing plates attached around a cylinder. Regarding the device, more specifically, several printing plates having grooves into which date stamps can be inserted are attached around a cylinder, and the printing plates are pressed onto the printing paper by raising and lowering the cylinder. In a printing machine that performs printing, an arm having a date stamp at the tip that can replace the date and that can be inserted into the groove is provided on the side of the cylinder so that it can rotate and move up and down. The present invention relates to a date stamp attachment device in a printing machine characterized by the following configuration.

To specifically explain one embodiment of the device according to the present invention, in FIG. 1, A is a printing machine used for certifying resident records, seals, etc. at municipal offices, etc.; On the outer periphery of the cylinder 1, which can be moved up and down, several letterpress printing plates 2 are detachably attached with text corresponding to residence certificates, seals, family registers, etc.; A groove 4 into which the mark 3 can be inserted is provided. A carbon tape 5 is tensioned around the cylinder 1, and as the cylinder 1 descends, a predetermined printing plate 2 and carbon tape 5 are pressed onto the printing paper to be certified placed on the table 6. It is configured so that the text on the printing plate 2 can be printed on the paper by pressing.

Next, the structure of the date stamp attaching device according to the present invention will be explained in detail. In FIGS. 2 to 6, the date stamp 3 is constructed so that the date can be inserted into the recess of the plate. At the same time, the tip of the arm 7 is bent into a key shape and is attached to the tip of the arm 7 via a bolt 8 so as to be able to stand up or fall down, and the arm 7 is attached to the lifting plate 9 horizontally via a screw 10. The elevating plate 9 is attached to a bar 12 via two shaft rods 11 so as to be movable up and down.
On the other hand, the bar 12 is fixed to a plate 13 horizontally fixed to a frame plate 16 which is fixed to the shaft of the cylinder 1 and can move up and down as the cylinder 1 goes up and down. A resilient spring 14 is fixedly attached via a nut 15, and the upper end of the shaft 11 protrudes from a hole bored in the plate 13. Reference numeral 17 is a lever capable of pushing down the elevating plate 9 at one end, and is pivoted to a hanging plate 18 fixed to the plate 13, and the other end is connected to a rotary solenoid 19.
It is configured such that the lifting plate 9 can be pushed down by the operation of a solenoid 19. Reference numeral 20 denotes a micro switch that comes into contact with the upper end of the shaft 11 that protrudes from the hole in the plate 13. Therefore, when the elevating plate 9 is raised, the switch 20 is operated to enable the cylinder 1 to be raised or lowered. The switch 20 does not operate when the elevating plate 9 is lowered, so that the cylinder 1 cannot be raised or lowered. In the figure, reference numeral 21 denotes a pawl, which is constructed so as to be able to mesh with a ratchet wheel 22 attached to the shaft of the cylinder 1, thereby regulating the rotation of the cylinder 1.

To explain the operation of the device according to the present invention,
First, rotate the cylinder 1 to select any print plate 2 for a resident's card installed around it and move it to the lowest end, then activate the solenoid 19 and move the elevating plate via the lever 17. 9 and the arm 7 pivoted thereto are lowered, and then the date stamp 3 is positioned below the groove 4 of the selected printing plate 2 by rotating the arm, and then the solenoid 19 is turned on. Spring 14 by cutting
The elevating plate 9 and the arm 7 are raised by the action of , whereby the date stamp 3 can be fitted into the groove 4, and the cylinder shaft is then moved by a cam device (not shown) or the like. By lowering the cylinder 1 and the plate 13, the lifting plate 9, the arm 7, and the date stamp 3, which are suspended from the cylinder 1 and the plate 13, are lowered together. Can be printed.

Also, in order to change the date on the date stamp 3 or to attach the date stamp 3 to another printing plate 2, the date stamp 3 can be attached to the printing plate 2.
In order to remove the cylinder, the cylinder 1, plate 13, elevating plate 9, arm 7, and date stamp 3 are each raised integrally by raising the cylinder shaft, and then the solenoid is activated to remove the elevating plate 9 and the date stamp. By lowering the arm 7 and rotating the arm 7 in this state, the date stamp 3 attached to the tip of the arm 7 is taken out, and if necessary, the date stamp 3 is rotated around the bolt 8. While standing up, replace and change the date typesetting embedded in the recess, then rotate the cylinder 1 as described above to select a predetermined printing plate 2, and then press the button in the groove 4 of this printing plate 2. The date stamp 3 can then be inserted into the printer and the printer is ready for printing. As described above, the device according to the present invention has several types of certification printing plates attached around the cylinder, and grooves into which date stamps can be inserted are formed in these printing plates, and the date stamps can be moved up and down and rotated. Since it is attached to the tip of a fixed arm, it is possible to combine one date stamp with several printing plates, which simplifies the overall structure and makes it extremely easy to change the date. It has the feature of being able to
