Embodiment Construction

[0029] figure 1 Shown is a part of a relatively large apparatus, which is used in the process of processing eg wafers. The term "wafer" here means a substantially plate-shaped element. In this context, plate shape means that the extension in the first and second dimensions is much greater than in the third dimension.

[0030] The device 1 separates the plate-type elements from the stack 2 . Such as figure 1 Shown on the right and left side of the stack 2, the stack 2 comprises a plurality of individual plate-type elements oriented parallel to each other. The plate-type elements are oriented in such a way that the stacking axis extending in the conveying direction indicated by the arrow is arranged perpendicular to the individual plate-type elements. The stack 2 is arranged in a horizontal position in the liquid pool. In this context, the term "horizontal" refers to the position adopted during operation. As indicated by the water lines, the stack 2 is arranged integrally ...

Abstract

The invention relates to a device for separating disc-shaped elements from a stack (2). The device has a first belt conveyor device (6) and a second belt conveyor device (7). The first belt conveyor device (6) is provided for receiving in each case one disc-shaped element from a stack (2). The second belt conveyor device (7) is provided for further transport and for the depositing of the disc-shaped elements on a transport device (8) which leads further. The first and the second belt conveyor devices (6, 7) are connected to a device (VP) which generates a vacuum. A first belt of the first belt conveyor device (6) has first openings and a second belt of the second belt conveyor device (7) has second openings. Here, the opening cross sections of the second openings are smaller than the opening cross sections of the first openings.

Description

technical field [0001] The invention relates to a device for separating plate-type elements from a stack. Background technique [0002] The use of belt conveyor devices for separating stacked plate-type elements is known, for example, from DE 10 2006 011 870 A1. The stack is moved towards the belt in the direction of its stacking axis. The belt itself is guided along the vacuum pressure device and provides openings through which the surrounding medium is sucked into the vacuum pressure device. With the surface of the elements of the stack to be separated in contact with the belt, a vacuum pressure is created which holds the elements to be separated on the belt. The direction of belt movement and the orientation of the stacking axis are set perpendicular to each other. As a result, the elements to be separated are withdrawn from the stack transversely with respect to the stack axis and supplied to the further conveying mechanism. [0003] In order to remove the next plate...
