Embodiment Construction

[0022] 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

The invention relates to a sheet delivery includes an endless conveyor (3) for conveying printed sheets (5), and also comprises a secondary gripper (10) with a gripper bar (11) by way of which the printed sheets (5) are received from the conveyor (3) at their trailing edges and deposited on a delivery stack (9), and a coupler transmission (14) for generating an annular circulatory movement (12) of the gripper bar (11). The coupler transmission (14) has criss-crossing oscillating cranks (20,21).

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 places the printed sheet on the delivery pile and the link drive for generating the circular rotary motion of the gripper bridge. Background technique [0002] Delivery devices of the type mentioned at the outset are described in DE 10343428A1 (corresponding to: US 7261291) and DE 10345703A1. These deliveries each comprise an endless conveyor in the form of a chain conveyor, on the endless chain of which there are gripper bridges for gripping the leading edge of the printed sheet and gripper bridges for simultaneously gripping the trailing edge of the printed sheet. Gripper bridge. The grippers are then picked up for a lengthwise swivel movement in the form of a ring, so that their ...
