Abstract

A system for overturning plate-shaped bodies, in particular slabs and sheets, having at least one overturn arm pivotally arranged about a pivot axis and can be brought into physical contact with a flat side of a plate-shaped body to be overturned, and at least one other overturn arm pivotally arranged about another pivot axis and can be brought into physical contact with another flat side of the plate-shaped body to be overturned. The two pivot axes are parallel to each other and mutually spaced. A permanent system is provided for overturning plate-shaped bodies with different dimensions, wherein noise generation associated with the overturning process is greatly reduced using the system. The system has at least one drivable eccentric arrangement with which a position of one of the pivot axes can be adjusted before and/or during an overturning process.

First claim

The invention claimed is:

1. A system for turning over plate-shaped bodies, comprising at least one turnover device arm arranged so as to be pivotable about a pivot axis and placeable in physical contact with a flat side of a plate-shaped body to be turned over; at least one further turnover device arm arranged so as to be pivotable about a further pivot axis and placeable in physical contact with a further flat side of the plate-shaped body to be turned over, wherein the two pivot axes are arranged parallel to and spaced apart from one another; and at least one driveable eccentric arrangement by which a position of one of the pivot axes is adjustable before and/or during a turnover process, wherein the drivable eccentric arrangement has at least one turnover device shaft and at least one eccentric member arranged on the turnover device shaft, wherein one of the turnover device arms is connected to the eccentric member.

2. The system according to claim 1 , wherein the at least one turnover device shaft is positionally fixedly arranged and the at least one eccentric member is a driveable eccentric bushing rotatably arranged on the turnover device shaft, wherein the one of the turnover device arms is rotatably connected to the driveable eccentric bushing.

3. The system according to claim 1 , wherein the at least one turnover device shaft is a driveable turnover device shaft arranged positionally fixedly and so as to be rotatable about its longitudinal central axis, and the at least one eccentric member is an eccentric body arranged on the drivable turnover device shaft and connected rotationally conjointly to the drivable turnover device shaft, wherein the one of the turnover device arms is rotatably connected to the eccentric body.

4. The system according to claim 1 , further comprising at least one measurement unit for measuring a respective thickness of the plate-shaped body to be turned over, and at least one set of system electronics connectable in terms of communication to the measurement unit, wherein the set of system electronics is set up to drive the driveable eccentric arrangement as a function of the respectively measured thickness of the plate-shaped body to be turned over.

5. The system according to claim 1 , wherein at least two of the turnover device arms are arranged so as to be pivotable about one of the pivot axes, wherein each turnover device arm is assigned a dedicated actuable drive unit, the drive units being independently actuable to pivot the respective turnover device arm about the pivot axis.

6. The system according to claim 1 , wherein at least two of the turnover device arms are arranged so as to be pivotable about one of the pivot axes and are immovably connected to one another by at least one connecting element, further comprising at least one mechanical damping element is arranged on a side of the connecting element facing toward the plate-shaped body to be turned over.

7. The system according to claim 1 , comprising at least two driveable eccentric arrangements that each have one positionally fixedly arranged turnover device shaft on which in each case at least one driveable eccentric bushing is arranged by at least one radial bearing, wherein in each case at least one turnover device arm is connected to the respective driveable eccentric bushing by at least one radial bearing, and wherein the turnover device shafts are arranged in alignment with one another.

8. The system according to claim 1 , comprising at least two driveable eccentric arrangements that each have one driveable turnover device shaft which is arranged positionally fixedly and so as to be rotatable about a longitudinal central axis and on which there is arranged in each case at least one eccentric body connected rotationally conjointly to the respective turnover device shaft, wherein in each case at least one turnover device arm is connected by at least one radial bearing to the respective eccentric body, and wherein the turnover device shafts are arranged in alignment with one another.

9. A method for turning over plate-shaped bodies, comprising the steps of: turning a plate-shaped body with a turnover system having at least one turnover device arm which is arranged so as to be pivotable about a pivot axis and which can be placed in physical contact with a flat side of the plate-shaped body to be turned over, and having at least one further turnover device arm which is pivotable about a further pivot axis and which can be placed in physical contact with a further flat side of the plate-shaped body to be turned over, wherein the two pivot axes are arranged parallel to and spaced apart from one another; and, adjusting a position of at least one of the pivot axes by at least one eccentric arrangement before and/or during a turnover process, the method further including measuring a respective thickness of the plate-shaped body to be turned and adjusting the position of the pivot axis by the at least one eccentric arrangement before and/or during the turnover process as a function of the measured thickness of the plate-shaped body to be turned over.

10. The method according to claim 9 , wherein at least two turnover device arms which are arranged so as to be pivotable about one of the pivot axes are pivotable jointly or independently of one another about the pivot axis.
