Abstract
A plate removal apparatus in a rotary printing press, which removes outside a printing unit a plate unfixed from a plate fixing unit of a plate cylinder in the printing unit includes a first guide member and a regulating member. The first guide member falls inside the printing unit in removing the plate from the plate cylinder to guide the plate removed from the plate cylinder outside the printing unit. The regulating member is interlocked with falling operation of the first guide member to prevent the plate guided by the first guide member from entering into the printing unit.
Claims9
A plate removal apparatus in a rotary printing press having a printing unit, said printing unit comprising:
- a first guide member adapted to move toward a plate cylinder in the printing unit for guiding a plate removed from said plate cylinder away from said printing unit;
- and
- a regulating member operatively coupled to move with said first guide member for preventing a plate guided by said first guide member from entering said printing unit.
A plate removal apparatus in a rotary printing press having a printing unit, comprising:
- a first guide member adapted to pivot towards a plate cylinder in a printing unit for guiding a plate removed from said plate cylinder away from said printing unit, said first guide member comprising a guide plate pivotally supported at a lower end and held substantially vertically at a first time,
- a regulating member operatively coupled to pivot with said first guide member for preventing a plate guided by said first guide member from entering said printing unit, said regulating member comprising a regulating plate pivotally supported at an upper end thereof and held substantially horizontally in said printing unit at said first time;
- and
- a link mechanism for operatively coupling said first guide member and said regulating member, wherein said regulating member is interlocked with the rotation of said first guide member through said link mechanism;
- said printing unit including an opening, said opening open in a horizontal direction;
- and
- wherein said guide plate is inclined at a predetermined angle at a second time, said regulating plate pivots through substantially 90° to a vertical state at said second time, thereby closing the opening through said link mechanism.
A plate removal apparatus in a rotary printing press having a printing unit comprising:
- a first guide member adapted to move toward a plate cylinder in the printing unit for guiding a plate removed from said plate cylinder away from said printing unit;
- a regulating member operatively coupled to move with said first guide member for preventing a plate guided by said first guide member from entering said printing unit;
- a plate catch member for holding a trailing edge of a plate removed from said plate cylinder through said first guide member;
- and
- a second guide member for guiding to said plate catch member said trailing edge of said plate guided by said first guide member, said second guide member further comprising:
- a guide portion extending horizontally from an end portion to a central portion in a plate removal path surface of said printing unit at a predetermined interval;
- and
- a leg for supporting said guide portion in a cantilevered manner;
- wherein said plate held by said plate catch member and said second guide member is removed from an open end side of said guide portion.
