Abstract
In a stencil printing device, a plurality of printing drums are mounted on a turret-like printing drum supporting member, and the indexing rotary movement of the printing drum supporting member and the rotary actuation of each of the printing drums thereon are effected by a common motor without regard to the number of the printing drums so that the overall structure can be simplified, and the control of the indexing rotary movement of the planetary plate disk and the rotary actuation of each of the printing drums can be accomplished in a centralized manner. The present invention is particularly useful in a stencil printing for full color printing.
Claims13
An assembly for supporting a plurality of printing drums for rotative actuation thereof in a multi printing drum stencil printing device, comprising:
- a fixed frame;
- a printing drum supporting member rotatably supported by said fixed frame around a central axial line of said printing drum supporting member;
- a plurality of cylindrical printing drums each adapted to have a stencil master plate sheet mounted around an outer circumferential surface thereof and mounted on said printing drum supporting member so as to be rotatable around an axial line parallel to said central axial line of said printing drum supporting member;
- a rotary actuator mounted on said printing drum supporting member, said rotary actuator having an output shaft;
- power transmitting means adapted to selectively and individually engage each of said printing drums with said output shaft of said rotary actuator;
- and
- printing drum supporting member driving means for effecting an indexing rotary motion of said printing drum supporting member.

- a printing drum supporting member rotatably supported by said fixed frame around a central axial line of said printing drum supporting member;
- a plurality of cylindrical printing drums each adapted to have a stencil master plate sheet mounted around an outer circumferential surface thereof and mounted on said printing drum supporting member so as to be rotatable around an axial line parallel to said central axial line of said printing drum supporting member;
- one, and only one first rotary actuator mounted on said fixed frame, said one first rotary actuator having an output shaft;
- power transmitting means adapted to selectively and individually engage all of said printing drums with said output shaft of said one first rotary actuator;
- and
- printing drum supporting member driving means including a second rotary actuator mounted on said fixed frame, and second power transmitting means for transmitting an output torque of said second rotary actuator to said printing drum supporting member, for effecting an indexing rotary motion of said printing drum supporting member.
