Problems solved by technology

[0004] Disadvantages of such adjustment devices are, on the one hand, their complex and complex construction
On the other hand, regulation accuracy leaves room for improvement
resulting in poor repeat accuracy
That is, for repeated tasks, the gap size should be chosen exactly as it was last performed, and such precise adjustments present difficulties

Embodiment Construction

[0027] figure 1 A processing machine 10 is shown which has a first drum 11 , a second drum 12 and a third drum 13 which are mounted in a frame 9 . In the illustrated embodiment, the converting machine 10 is a flexographic printing machine, wherein the first cylinder 11 is embodied as a printing plate cylinder, the second cylinder 12 is embodied as an anilox roller and the third cylinder 13 is embodied as a counterpress. printing cylinder. The second roller 12 and the third roller 13 are mounted stationary in the frame 9 . In contrast, the first roller 11 is mounted movably on a rocker arm 19 in the machine frame 9 . A pneumatic cylinder 14 is installed on the rocker arm 19, and the pneumatic cylinder 14 constitutes a tensioning mechanism, and is used to press the first roller 11 together and press it to the above two fixed rollers 12 with a force F, that is, a pre-tightening force. , 13 on. Axially and on both sides with respect to the first drum 11 , on the axis of rotati...

Abstract

The invention relates to a processing unit (10), for the rotational processing of a web-shaped or sheet-shaped substrate (1000), including a machine frame, at least a first processing cylinder (11) movably mounted in the machine frame (9), a second processing cylinder (12) stationarily mounted in the machine frame (9), and a pair of support members (20, 30) associated with each respective processing cylinder (11, 12, 13). A respective support member (20) of the second processing cylinder (12) has a solid joint (21), a manipulator (24) and an annular segment (23) attached to the solid joint andcontacting one support member (30) of the first processing cylinder (11). A solid joint (21) is linearly displaceable (v) by the manipulator (24) and an annular segment (23) is linearly displaceabletherewith. A gap dimension between the processing cylinders (11, 12, 13) of the processing unit (10) can therefore be adjusted in a simple, accurate manner with precise repeatability.

Description

technical field [0001] The invention relates to a processing machine for rotary processing having the features stated in the preamble of claim 1 and to a label printing machine according to claim 9 having such a processing machine. Background technique [0002] In a label printing machine such as that described in EP 2 103 429 B1, a printing mechanism and a die-cutting mechanism are used. The printing machine comprises at least three cylinders, namely: an ink application roller, an impression cylinder and a counter impression cylinder. The rotary process here facilitates the application of the ink to the substrate. A die-cutting machine comprises at least two cylinders, namely: a die-cutting cylinder and a counter-die-cutting cylinder. The rotary processing facilitates the introduction of die-cutting lines and / or corrugation lines. In order to adapt to the substrate to be treated and to adjust the cutting depth, the gap, ie the distance between the cylinders, must then be...
