Embodiment Construction

[0025] figure 1 The schematic design of a sheet die-cutting and embossing machine 100 for die-cutting, stripping, separating useful parts and depositing sheets made of paper, cardboard, plastics and the like is shown in FIG. The die-cutting and embossing machine 100 comprises a feeder 1, a die-cutting station 2, a stripping station 3 and a receiver 4 with a placement and useful part separation station 20, which consist of a common machine housing 5 carries and surrounds and is driven by the main driver 17. The processing stations 2 , 3 , 4 are accessible from one side, the so-called operator side; the drive train of the sheet-cutting and embossing machine 100 is located on the opposite side, the so-called drive side. A corresponding machine control device 15 controls the processes within the die-cutter 100 .

[0026] The sheets 6 are separated from a stack by means of a feeder 1 via so-called suction heads 18 , fed to the sheet conveyor system 7 at the sheet transfer point U...

Abstract

The invention relates to a method for transferring sheets from a sheet feeder to a sheet conveying system, the sheets and the gripper carriage entering the sheet transfer point without collision. The invention also relates to a sheet die-cutting and / or embossing machine with a sheet feeder, at least one processing station and a sheet transport system with intermittently rotating gripper carriages In order to transport the sheet through the sheet die-cutting and / or embossing machine in the sheet running plane, a corresponding gripper carriage has a plurality of grippers for gripping the sheet, the sheet Transferred from the feeder to the sheet transport system at the sheet transfer point. According to the invention, the respective gripper has a gripper seat and a gripper bar, the respective gripper seat or the respective gripper bar can be pivoted or slid below the sheet running plane to open said gripper so that The jaws can be opened further and run the plane through the sheets earlier.

Description

technical field [0001] The invention relates to a method for transferring sheets as claimed in claim 1 and to a sheet cutting and / or embossing machine as described in the preamble of claims 3 or 6 . Background technique [0002] Cutting with a cutting die of a closed geometry, which can be round, oval or polygonal and any kind of irregular shape, is called "die cutting". Processes performed in post-press processing such as die-cutting with punches, corner cutting and index die-cutting also belong to this field. Die-cutting is carried out against a die-cutting block or against an impression, partly also a shearing process. Packaging materials made of paper, cardboard, cardboard or corrugated are mainly die-cut in sheet format. It is also possible to additionally apply stripe lines or arches in the useful part during the die-cutting process. This complex process makes it absolutely necessary that the sheets are die-cut individually. Since the final product involves packagi...
