Problems solved by technology

At this time, if the trailing edge of the paper hangs due to the instability or swing of the paper, the hanging trailing edge comes into slidable contact with the surface of the uppermost sheet of paper stacked on the paper loading device, thereby damaging the The surface of the paper, resulting in waste of paper
In the above-mentioned third apparatus, when the printing proof sheet is taken out, it comes into slidable contact with the upper surface of the paper immediately below it, thereby damaging the upper surface of the paper, thereby causing waste of paper

Abstract

A sheet delivery apparatus includes sprockets and delivery grippers, a sheet delivery device, a switching cam, and conveyor belt, driving roller, and driven roller. The sprockets and delivery grippers hold and convey a sheet. The sheet delivery device delivers the sheet conveyed by the sprockets and delivery grippers. The switching cam is arranged upstream of the sheet delivery device in a sheet convey direction to release the sheet held by the sprockets and delivery grippers. The conveyor belt, driving roller, and driven roller are arranged below the switching cam to convey the sheet released by the switching cam in the sheet convey direction.

Description

technical field [0001] The invention relates to a delivery apparatus capable of printing from sheets printed by a printing unit in a sheet-fed web offset press and stacked on a stacker of a delivery without stopping the printing press , take out every predetermined number of sheets as printing proofs or inappropriate sheets generated at the start of printing or due to printing overprint errors. Background technique [0002] As shown in Japanese Patent Laid-Open Document No. 58-047749, a conventional paper delivery apparatus includes: a paper loading device on which printed paper is stacked; provided downstream of the paper loading device; a switching cam provided above the paper loading device; and a fixed cam provided above the discharged paper receiver. In this structure, the switching cam withdraws from the running path of the delivery claw by switching. When the running delivery dog ​​abuts the fixed cam, it releases the paper. Paper is delivered not to the paper load...
