Printing press with means for connecting and disconnecting motors for oscillating roller

A printing press, comprising:

• a first rotary member;
• a first motor for rotating said first rotary member;
• a second rotary member rotatable by said first motor, the second rotary member movably supported in an axial direction;
• a second motor for moving said second rotary member in the axial direction and for rotating said second rotary member;
• means for connecting or disconnecting, thereby permitting and stopping transmission of rotation from said first motor to said second rotary member;
• and
• a clutch for stopping transmission of rotation from said second motor to said second rotary member when said first motor is connected to said second rotary member by said means for connecting or disconnecting, so that said first motor can rotate said second rotary member, and for connecting said second motor to said second rotary member, so that said second motor can rotate said second rotary member when transmission of rotation from said first motor to said second rotary member is stopped by said means for connecting or disconnecting, while rotational force of said second motor oscillates said secondary rotary member of said second rotary member in said axial direction;
• and
• an oscillation mechanism for converting rotation transmitted from said second motor to reciprocating motion of said second rotary member;
• an oscillation-width adjustment mechanism for adjusting an oscillation width of said second rotary member;
• and
• oscillation-width adjustment means for operating said oscillation-width adjustment mechanism;
• wherein
• said oscillation mechanism includes,
• a swing member which swings upon operation of said motor,
• a moving member movably supported on said swing member, and
• an engagement member rotatably supported on said moving member and being in engagement with said second rotary member, and wherein
• said oscillation-width adjustment mechanism is configured such that, upon operation of said oscillation-width adjustment means, said oscillation-width mechanism moves said moving member to thereby adjust a distance between a swing center of said swing member and a rotation center of said engagement member.

• a slide lever slidably supported by said swing lever such that the distal end side of said slide lever can move toward and away from a swing center of said swing lever,
• a first link plate whose one end side is rotatably supported by the distal end side of said slide lever,
• a swingably-supported swing plate, the other end side of said first link plate being rotatably connected to the base end side of said swing plate, and
• a cam follower provided at the distal end side of said swing plate and inserted into a groove wheel of said second rotary member, and wherein
• said oscillation-width adjustment mechanism includes,
• a worm gear connected to said oscillation-width adjustment means,
• a worm wheel in meshing engagement with said worm gear,
• a transmission shaft coaxially connected to said worm wheel,
• a second link plate whose one end side is connected to said transmission shaft, and
• said slide lever whose base end side is rotatably connected to the other end side of said second link plate.
