Claims
- 1. An ink feeder driver for a rotary press having a printing cylinder (5) rotatable in either of two directions and an ink cylinder required to be rotated only in a predetermined direction, means for driving said pringing cylinder in either of two rotational directions, means for drivingly connecting said printing cylinder with said ink cylinder and for rotating said ink cylinder in a predetermined single rotational direction irrespective of the direction of rotation of said printing cylinder comprising:
- a first gear (1) connected to said ink cylinder and rotating about an axis (11) in a direction matched to the direction of rotation of said ink cylinder;
- a second gear (2) rotating about an axis (21) fixedly disposed with respect to said first gear and connected to said printing cylinder (5) to rotate in the same direction thereof;
- a first idle gear (3) fixedly positioned and at all times meshed with said second gear (2);
- a second at least one idle gear (4,4') meshed at all times with said first gear (1) and engagable with one of said second gear (2) and said first idle gear (3);
- a displacing means (10) rotatable about an axis (11 or 21) and carrying said second at least one idle gear (4,4') rotationally thereon; and
- means (19) for rotating said displacing means (10) about its axis (11 or 21) so as to selectively move said second at least one idle gear (4,4') between a first position wherein it is in mesh with said second gear (2) and a second position wherein it is in mesh with said first idle gear (3).
- 2. An ink feeder driver as recited in claim 1, wherein said second at least one idle gear comprises a single idle gear (4) that meshes with said second gear (2) in said first position and meshes with first idle gear (3) in said second position.
- 3. An ink feeder driver as recited in claim 1, wherein said second at least one idle gear comprises one gear (4') that meshes with said second gear (2) in said first position, and another gear (4) that meshes with said first idle gear (3) in said second position.
- 4. An ink feeder driver as recited in claim 1 further including displacement detection means for detecting the position of said displacement means in said first and second positions and for inhibiting rotation of said printing cylinder when said displacement means is not positioned to drive said ink cylinder to rotate in said predetermined direction.
- 5. An ink feeder driver as recited in claim 1 further including signal generator means connected to a driving means for said printing cylinder to provide a signal determined by the direction of rotation of said driving means, and means responsive to said signal for switching said displacing means between said first position and said second position to drive said ink cylinder to rotate in said predetermined direction.
- 6. An ink feeder driver as recited in claim 3 further including displacement detection means for detecting the position of said displacement means in said first and second positions and for inhibiting rotation of said printing cylinder when said displacement means is not positioned to drive said ink cylinder to rotate in said predetermined direction.
- 7. An ink feeder driver as recited in claim 3 further including signal generator means connected to a driving means for said printing cylinder to provide a signal determined by the direction of rotation of said driving means, and means responsive to said signal for switching said displacing means between said first position and said second position to drive said ink cylinder to rotate in said predetermined direction.
