DESCRIPTION:
BRIEF SUMMARY
The invention relates to a apparatus for cutting stacked, sheet-like material, having a table surface which has a working zone, above which a cutting blade and a press beam are located, an entry zone behind it for receiving the material to be cut and an exit zone in front of it for receiving the cut material, and a feed device for the material to be cut, in which arrangement the exit zone is movable relative to the working zone while forming a gap, and a transverse channel leading to a further-processing station is provided on the exit zone, which transverse channel is formed by a first straightedge which can interact with the exit zone and can be brought into a working position and by a second straightedge which is located behind the first straight-edge and can be brought into its working position after the gap is opened, and an ejector movable along the transverse channel is also provided.
DE No. 3,613,316 C1 discloses an apparatus of this type which is used as a second cutting apparatus of a cutting system in which a first cutting apparatus is designed for producing block strips by parallel longitudinal cuts, while the block strips are cut in the transverse direction by the second cutting apparatus so that individual blocks result. Efficient production is obtained through the use of two cutting apparatuses which are each designed for one function, namely, on the one hand, longitudinal cutting for producing the block strips and, on the other hand, transverse cutting of these block strips. In the known system, it is a disadvantage that two cutting apparatuses are required for cutting the block strips, which involves high system production costs.
The object of the present invention is to further develop an apparatus of the said type in such a way that, with this apparatus, that is, with a single cutting apparatus, both functions of longitudinal and transverse cutting of the block strips can be performed with minimum, manual effort and the cut blocks can be fed to the further-processing station in a simple manner In addition, the apparatus should also enable conventional cutting operations, that is, main, marginal and intermediate cuts, to be carried out
The object is achieved according to the invention in that the exit zone is subdivided into a first zonal area adjacent to the working zone and a second zonal area arranged in front of the first zonal area, and the first straightedge is arranged below the exit zone in the area of the parting surface of the two zonal areas, in which arrangement the second zonal area can be lifted from the position forming a plane with the first zonal area, and the first straightedge can be lifted and moved into the working position with the first zonal area of the exit zone. Here, working position need not necessarily be understood as a defined position of the first straight-edge; on the contrary, a plurality of positions of the straightedge with regard to the first zonal area of the exit zone are conceivable.
Through the design according to the invention of the exit zone having a first and second zonal area as well as a straightedge arranged below the exit zone, the desired different functions can be performed by the apparatus. Thus the apparatus, when the second zonal area is lowered, which in this position forms a plane with the first zonal area and a working zone as well as the entry zone, works in accordance with the apparatus described in European Patent No. 0,056,874. The first and second zonal area hereby form a unit movable in the feed direction of the material to be cut and in the opposite direction, with the means of creating a gap between this unit and the working zone for disposing of the shavings collecting during a marginal or intermediate cut. When the second straightedge is transferred into its working position after the gap is opened, this straightedge pushes the cut set, projecting beyond the first zonal area on account of the automatically set-back position of the cutting strip and the cutting blade, completely onto the exit zone so that it cannot be caugh
