Embodiment Construction

[0026] figure 1 Part of a printing press 1 for inkjet or offset printing is shown, comprising a stocker 2 with a chain conveyor 3 with a gripper bridge 4 for feeding substrates The sheets are transported along the transport direction T to the stacking device 5 . The collected sheets form a stack (not shown here together in the figures) on a vibrating plate 6 which is arranged on a chassis 7 which is arranged on a lift table 8 . The chassis 7 can be generally expressed as a bracket 7 .

[0027] The vibrating plate 6 and thus the sheet stack on it is moved by a vibrator or other oscillating drive in order to assist the sheet at least one front stop 9 (and preferably several front stops 9) and at least one side stop 23 (and preferably a plurality of side stops 23) (see Figure 12 ) on the vibrating plate 6 for orientation. These front stoppers 9 and side stoppers 23 are sometimes referred to as shock stoppers 9 , 23 hereinafter.

Abstract

The invention relates to a printing machine comprising a stacking device (5) with a vibrating plate (6) movable in vertical direction, adjustable from a horizontal position to an inclined position state, and is equipped with at least one first front stopper (9), and also includes at least one second front stopper (12), the second front stopper is separately and independently arranged relative to the vibrating plate, wherein, When the vibrating plate (6) is adjusted to an inclined position, the first front stopper (9) is adjusted together, and at least one of the two front stoppers (9, 12) can be moved along the in the longitudinal direction (x) or against the longitudinal direction (x) in order to compensate for horizontal misalignment between the first front stop (9) and the second front stop (12), which would otherwise be caused by the first The front stop (9) occurs as the vibration plate (6) is adjusted to the tilted position.

Description

technical field [0001] The invention relates to a printing machine comprising a stacking device having a vertically movable vibrating plate adjustable from a horizontal position to an inclined position and equipped with at least one first The front stop further comprises at least one second front stop arranged independently of the vibrating plate, wherein when the vibrating plate is adjusted to an inclined position, the first front stop are adjusted together. Background technique [0002] Such a printing press is described in document DE 10 2017 215 360 A1, wherein the problem of a horizontal misalignment between the two front stops in the case of an oblique mounting of the vibrating plate has not yet been recognized. The first front stop may be fixedly mounted on the vibrating plate (referred to herein as the stack carrier) and preferably corresponds in a manner not described in more detail to those vertically fixed front stops, or instead of The latter (those front stops...
