Apparatus for removably securing a cutting component
View Patent ↗An apparatus for removably securing a cutting component on a cutting component cylinder of a web printing press includes a first axial anvil member disposed at a periphery of the cutting component cylinder and a second axial anvil member disposed at the periphery of the cutting component cylinder opposite the first anvil member. The first and second anvil members receive the cutting component between them. A locking device is provided for positively securing the cutting component on the cutting component cylinder in a lock mode and positively releasing the cutting component in a release mode.
1. An apparatus for removably securing a cutting component on a cutting component cylinder of a web printing press, the apparatus comprising:
a first axial anvil member disposed at a periphery of the cutting component cylinder;
a second axial anvil member disposed at the periphery of the cutting component cylinder opposite the first anvil member, the first and second anvil members being configured for receiving the cutting component therebetween; and
a locking device configured for positively securing the cutting component on the cutting component cylinder in a lock mode and positively releasing the cutting component in a release mode;
the first and second anvil members being configured for clamping the cutting component therebetween in the lock mode;
the locking device including a turnable eccentric member configured for urging at least a portion of the second anvil member toward the first anvil member so as to achieve the lock mode in a first angular position of the eccentric member and for permitting at least the portion of the second anvil member to move away from the first anvil member so as to achieve the release mode in a second angular position of the eccentric member;
wherein, in a third angular position of the eccentric member between the first and the second angular positions, at least the portion of the second anvil member is closer to the first anvil member than when the eccentric member is in the first angular position.
2. The apparatus as recited in claim 1 wherein the first anvil member is fixed relative to the cutting component cylinder.
3. The apparatus as recited in claim 1 wherein the eccentric member is an elongated axial member disposed adjacent to the second anvil member.
4. The apparatus as recited in claim 1 wherein the eccentric member is an eccentric disc received in a slot defined by the second anvil member.
5. The apparatus as recited in claim 1 wherein the cutting component cylinder is an anvil cylinder and the cutting component is a cutting rubber.
6. The apparatus as recited in claim 1 wherein the second anvil member is movable relative to the first anvil member.
7. The apparatus as recited in claim 6 wherein the second anvil member is configured for pivoting about a pivot axis fixed relative to the cutting component cylinder.
8. An apparatus for removably securing a cutting component on a cutting component cylinder of a web printing press, the apparatus comprising:
a first axial anvil member disposed at a periphery of the cutting component cylinder;
a second axial anvil member disposed at the periphery of the cutting component cylinder opposite the first anvil member, the first and second anvil members being configured for receiving the cutting component therebetween; and
a locking device configured for positively securing the cutting component on the cutting component cylinder in a lock mode and positively releasing the cutting component in a release mode; the first and second anvil members being configured for clamping the cutting component therebetween in the lock mode; wherein the locking device includes a turnable eccentric member configured for urging at least a portion of the second anvil member toward the first anvil member so as to achieve the lock mode in a first angular position of the eccentric member and for permitting at least the portion of the second anvil member to move away from the first anvil member so as to achieve the release mode in a second angular position of the eccentric member, and at least one of a tab-and-slotted clip device and a cutout-and-sprung block device for positively holding the eccentric member in at least the lock mode;
wherein, in a third angular position of the eccentric member between the first and the second angular positions, at least the portion of the second anvil member is closer to the first anvil member than when the eccentric member is in the first angular position.
9. A web printing press comprising:
a first axial anvil member disposed at a periphery of a cutting component cylinder of the printing press and fixed relative to the cutting component cylinder;
a second axial anvil member disposed at the periphery of the cutting component cylinder opposite the first anvil member and configured for pivoting about a pivot fixed relative to the cutting component cylinder, the first and second anvil members defining an axial groove configured for receiving a cutting component; and
a turnable eccentric member configured for urging at least a portion of the second anvil member toward the first anvil member so as to clamp the cutting component between the first and second anvil members in a first angular position of the eccentric member, and for permitting at least the portion of the second anvil member to move away from the first anvil member so as to release the cutting component in a angular position of the eccentric member, the first angular position being an over-toggle position.
10. An apparatus for removably securing a cutting component on a cutting component cylinder of a web printing press, the apparatus comprising:
a first axial anvil member disposed at a periphery of the cutting component cylinder;
a second axial anvil member disposed at the periphery of the cutting component cylinder opposite the first anvil member, the first and second anvil members being configured for receiving the cutting component therebetween; and
a locking device configured for positively securing the cutting component on the cutting component cylinder in a lock mode and positively releasing the cutting component in a release mode;
the first and second anvil members being configured for clamping the cutting component therebetween in the lock mode, the second anvil member being movable relative to the first anvil member, and the second anvil member being configured for pivoting about a pivot axis fixed relative to the cutting component cylinder so as to move at least a portion of the second anvil member toward the first anvil member and achieve the lock mode in a first angular position of the second anvil member and so as to achieve the release mode in a second angular position of the second anvil member;
wherein, in a third angular position of the second anvil member between the first and the second angular positions, at least the portion of the second anvil member is closer to the first anvil member than when the second anvil member is in the first angular position.
