Description of the Invention () Technical Field of the Invention The present invention relates to the improvement of the cylinder reciprocating drive mechanism of all printing equipment such as ordinary printing equipment or convex printing. Conventional technology In conventional printing equipment, such as a hawker printing device, when a printing cylinder such as an offset cylinder is driven to and fro, for example, the printing cylinder is pseudo-rolled on the printing target surface during forward movement, but the printing cylinder is repeatedly moved It moves away from the printing target surface. In this double-acting state, the print cylinder 傺 stops rotating or rotates in the opposite direction to the rotating direction of the forward-moving state. Therefore, at least at the time of the change of the forward movement and the double movement, the print cylinder and the vending cylinder have to be stopped temporarily. The problem to be solved by the invention is as described above. When the printing cylinder and the sales cylinder temporarily stop rotating at the time of the transition between the forward movement and the repeated movement, the transfer condition of the junction between the printing cylinder and the sales cylinder in this state is similar to other The parts are different, so the problem of line printing disorder occurs on the printing surface. Furthermore, it is difficult to increase the printing speed due to the reciprocating driving of the printing cylinder. Therefore, an object of the present invention is to provide a printing mechanism which can constantly rotate continuously in the same direction when reciprocatingly driving a printing cylinder, thereby preventing printing confusion and improving printing speed. The technical solution to solve the problem The application of the printing device in the scope of patent application No. 1 that transfers the image printed on the printing cylinder to the flat-shaped printing object surface, including ... at a specified width * * 4 ~ This paper size applies China National Standard (CNS) A4 Specification (210 X 297 mm) 1 ----------------- I-- · --Order '--------- Line-(Please read the precautions on the back before filling this page) Printed by the Employees' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 561104 A7 B7 V.

Invention Explanation () The cross arm 33 A held down from the dotted line position to the solid line position. Therefore, the rack 3A fixed below the cross arm 33A is turned from the meshed state with the pinion 11 shown by the broken line to the state shown by the solid line, and the meshed state is released. At this time, the cross arm 33B supported freely by the rotation shaft 32B is lowered from the dotted line position to the solid line position. Therefore, the rack 3B fixed on the cross arm 33B will rotate from the broken line state to the solid line state and mesh with the pinion 11. The state at this time is shown in FIGS. 3 and 4. Next, when the longitudinal arm 31 of the link mechanism 3 is raised to the dotted line position, the horizontal arm 33 A supported freely by the rotation shaft 32 A is raised from the solid line position to the dotted line position. Therefore, the rack 3A fixed under the cross arm 33A is in a state of meshing with the pinion 11. At this time, the cross arm 33B supported freely by the rotation shaft 32B is raised from the solid line position to the dotted line position. Therefore, the rack 3B fixed on the cross arm 33B is rotated from the solid line state to the broken line state, and the engagement with the pinion 11 is released. The state at this time is shown in FIGS. 5 and 6. In this way, by turning the longitudinal arm 31 of the link mechanism 3 up and down, the pinion 11 can be selectively engaged with any one of the upper and lower pairs of racks 3A, 3B. Therefore, FIG. In Figures 3 and 5, when the pinion 11 meshes with the lower rack 3A and rotates to the right, the offset cylinder 1 rotates clockwise, and when it engages with the upper rack 3B and resets to the left, _print cylinder 1 also Turn clockwise. In this manner, the rotation direction of the offset cylinder 1 is the same clockwise direction when reciprocatingly moved regardless of the engagement with any rack. -6- This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) " 7- I ----------- 111 ^-i 11 .----- Line-(Please read the precautions on the back before filling this page) Printed by the Employees' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 561104 A7 _B7 _ V. Description of the invention () As a result, both offset printing cylinder 1 and hawking cylinder 2 can be constantly rotated continuously. It will not stop. Therefore, in the conventional printing device, the disordered printing of the strips in the stopped state no longer occurs. Secondly, as shown in FIG. 7, a longitudinal arm 31C formed with strip teeth may be provided instead of the longitudinal arm 31 of the link mechanism 3, or a pinion 33C, which is coaxially connected to the rotating shafts 32A, 32B, 33D replaces the cross arms 33A, 33B. In the structure of FIG. 7, by driving the trailing arm 31C up and down, the upper and lower racks 3A and 3B can be alternately engaged with the pinion gear 11. In addition, it is preferable that the mechanism for driving the vertical arm 31C to move up and down can be coordinated with the repetitive action mechanism 20 so that the actions can cooperate with each other. The reciprocating lever 4 constituting the reciprocating mechanism 20 is reciprocally driven in the direction of an arrow by a mechanism (not shown) or the like that can convert a rotary motion of a power source such as a motor into a reciprocating motion. In addition, the rotation driving mechanism in which the rotation direction of the offset cylinder in the forward movement state is the same as the rotation direction of the offset cylinder in the double movement state is not limited to the example shown in the figure. Action. Alternative to replace the rotating action of the upper and lower racks. Such alternative conversion mechanisms can adopt various designs and are not limited to the above-mentioned structure. Cylinders, hydraulic cylinders, and solenoid coils can be used. EFFECT OF THE INVENTION According to the printing device of the present invention, the rotation direction of the printing cylinder in the forward motion state and the rotation direction of the printing cylinder in the double motion state are made the same by the rotation driving mechanism, so the contact surface between the printing cylinder and the printing cylinder does not occur. The continuous situation can prevent the lack of disordered printing lines on the printing surface, which can be improved. -7-This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) Γ -----^- ------------- It · — —1111 — ^ I -l · (Please read the notes on the back before filling this page) 561104 A7 B7 V.
