Abstract
An apparatus for assembling and depositing book signatures by means of signature-receiving compartments which are movable independently of one another and independnetly of a common rotary hub on which the compartments are carried to provide improved signature receiving, stacking, aligning and discharge, among other benefits.
Claims19
In an apparatus for assembling and depositing signatures including input compartments formed by generally radially projecting vane means on an impeller wheel that is rotatably driven synchronically with a signature assembly cycle and ejecting means for ejecting the signatures from said input compartments and onto a removal means, the combination comprising:
- pivotal mounting means mounting said vane means for pivotal movement thereon about respective axes which extend generally parallel to the rotary axis of said impeller wheel;
- control means for controlling pivotal movement of said vane means about said respective axes during regular rotary movement of said wheel about said rotary axis such that the said vane means of each said compartment to be loaded with such signatures is initially moved independently of others of said vane means in a phase of quick insertion movement, with respect to the rotary movement of said wheel, to an initial signature input position to receive such signatures followed by a phase of relatively slower movement in an assembly angle region during assembly of such signatures therein and a subsequent phase of relatively quicker movement to a final signature input position.
An apparatus for assembling and depositing signatures comprising:
- a wheel means rotatably mounted on an axis of rotation;
- a plurality of signature receiving compartment means carried by said wheel means;
- each said compartment means being pivotally movable with respect to said wheel means and independently of all others of said compartment means;
- and control means for controlling the independent pivotal movement of each of said compartment means with respect to said wheel means and said others of said compartment means in a manner that the movement of said compartment means due to the influence of said control means and the rotation of said wheel means for assembly of such signatures within said compartment means includes an initial phase of movement faster than the relative rotary movement of said wheel means to an initial signature insertion position followed in sequence by a second phase of movement within a given angle of rotation from said initial position at a rate slower than said initial phase of movement and a third phase of movement to a final signature input position at a rate faster than said second phase of movement.
