Safety device for machines for mechanical parts first perform the work operation on the moving machine part to the second

摘要

To provide a safety device in order to achieve optimal protection of the operator In the machine tool issues. [SOLUTION] safety device is provided with an optical safety barrier multiple evaluation unit (130,134,138,148,156) and (36). So as to move in different spaced prior to (32) the edge (14, 18, 20) machines the first part, the optical safety barrier, mechanical components of the first in (28) tool movement At the same time I want to move. The optical safety barrier, which extends to the (124) protection field with a two-dimensional cross-section. The evaluation unit generates a stop signal for stopping the machine part of the first in dependence on the optical safety barrier. Toward the end of the tool movement, the optical safety barrier is held in a substantially stationary state in the region (16,22,24) mechanical parts of the second. Before the mechanical parts of the first intercept the optical safety barrier, the evaluation unit stops sequentially from one minute to the next the optical safety barrier. [Selection Figure Figure 4
