Embodiment Construction

[0025] figure 1 A printing press 1 is shown in detail. The printing press 1 is a sheet-fed offset rotary printing press. The detail shows the delivery 2 of the printing press 1 . The paper delivery device 2 includes a circular conveyor 3, which is a chain conveyor. The endless conveyor 3 comprises, on the drive side and on the operating side, an endless chain for carrying the gripper bridges 4 and an endless chain for carrying the gripper bridges 6 for gripping the printed sheets 5 The leading edge of the gripper tooth bridge 6 is used to grip the trailing edge of the printed sheet 5 . Shown are the advancing branch 7 of the endless chain carrying the gripper bridges at the leading edge of the sheet on one machine side and the return branch 8 of the endless chain carrying the gripper bridges at the trailing edge of the sheet on the same machine side. The forward branches of all four endless chains run in the horizontal direction towards the delivery pile 9 on which the pri...

Abstract

A sheet delivery has an endless conveyor for conveying printed sheets and a secondary gripper with a gripper bar for holding printed sheets received at their trailing edges from the endless conveyor, to be deposited on a delivery stack. A transmission generates an annular circulatory movement of the gripper bar. A first balance weight and a second balance weight are provided for compensating for interference torques and are braced for rotation in relation to one another by a spring.

Description

technical field [0001] The invention relates to a delivery comprising a circular conveyor for conveying printed sheets and a re-grab gripper with a function for conveying printed sheets from the circular conveyor on the trailing edge of the printed sheets. The gripper bridge that takes over and collects the printed sheet on the delivery pile and the transmission device for generating the circular rotary motion of the gripper bridge. Background technique [0002] The delivery usually includes an endless conveyor in the form of a chain conveyor. In some deliveries with chain conveyors, the chain carries not only the gripper bridges that grip the leading edge of the sheet to be conveyed, but also the grippers that grip the trailing edge of the sheet bridge. In these delivery devices, which grip not only the leading edge of the respective printed sheet but also the trailing edge of the printed sheet, so-called recapture grippers must be present in order to ensure precise colle...
