Abstract

PURPOSE:To facilitate regulation of the discharge timing of an upper folded quire by a method wherein a distance between the outlet end of an upper stage conveyance belt and the outlet end of a lower stage conveyance belt is regulated. CONSTITUTION:An upper bent quire 40a folded at right angles by an upper stage folding blade 1a is creased by means of upper stage folding rollers 2a and 3a and is fed between upper stage conveyance belts 4a and 5a. Similarly, a lower folded quire 40b is fed between lower stage conveyance belts 4b and 5b. Thereafter, the upper and lower folded quires 40a and 40b nipped between the upper and lower stage conveyance belts for conveyance are alternately dropped between the vanes of an impeller 64. A distance between two belt outlet ends is regulated to an angle alpha=70 deg.+ or -15 deg. by rocking a bracket 28 around the rotary central axis of the impeller 64. As a result, the lower folded quire 40b is prevented from disturbance of the drop of the upper folded quire 40a between the vanes.

(Function) The paper discharge device of the rotary printing press of the present invention is configured as shown in the illustration below, and the upper conveyance heald is driven by a drive system different from the drive system of the folding rollers, and the lower conveyance belts 1 to 1 are folded. When driven by a drive system separate from the rollers, the upper folding blade folds the upper folded document at right angles, and the upper folding roller makes a crease between the upper conveyor belts and the upper fold replay 1. The lower folded document is folded at right angles by the lower folding roller and sent to the lower transport heald.
They are held and conveyed by the p-feeding heald, and the lower signature is held and conveyed by the lower conveyance belt, and dropped alternately between the blades of one impeller. In addition, when changing the length of the conveyance path of the upper conveyor belt, if the movable arcuate bracket is supported in a row by the same arcuate bracket, the conveyor belt is wrapped around a plurality of guide rollers with angles of 30' or less. activating a conveyance path length adjustment device for the upper conveyance belt having
- While changing the length of the conveyance path of the upper conveyance belt, the tension adjustment device is operated to adjust the tension that changes as the length of the conveyance path of the upper conveyance belt changes. In addition, when changing the distance between the protruding end of the upper conveyor belt 1- and the outlet end of the lower conveyor belt, the bracket supporting the exit side guide roller of the upper conveyor belt is swung around the central axis of rotation of the impeller. Then, adjust the distance between the exit 1] end of the upper transport belt and the exit end of the lower transport belt.
