Method and devices for workpiece separation and for dividing up a remaining grid of a workpiece separation

A shredding device for shredding a scrap skeleton produced as a machining product of separating machining of a plate-like workpiece and having a scrap skeleton main plane,

• wherein
• the shredding device is configured to create an incomplete joint having a course along a separating line running in a longitudinal direction of the incomplete joint on the scrap skeleton, wherein the shredding device comprises a scrap skeleton separating device and a device for producing a residual connection, wherein the scrap skeleton is machined for separation along the separating line by the scrap skeleton separating device, and wherein the residual connection, which is arranged along the separating line. is established between a first scrap skeleton part, arranged on a first side of the incomplete joint and forming a free end of the scrap skeleton, and a second scrap skeleton part, arranged on the second side of the incomplete joint as a remaining scrap skeleton, and
• the shredding device further comprises a deflection device, the deflection device is configured to, after the incomplete joint is created, deflect the first scrap skeleton part and the second scrap skeleton part relative to one another perpendicularly to the scrap skeleton main plane in such a way that the residual connection between the first scrap skeleton part and the second scrap skeleton part breaks, thereby separating the first scrap skeleton part and the second scrap skeleton part from one another.

The machining device as claimed in claim 17, further comprising:

• a workpiece advancing device, wherein the workpiece to be machined for separation is capable of being arranged in a machining position by the workpiece advancing device by a positioning movement in a workpiece advancing direction, and
• a workpiece support configured to support the workpiece, which is arranged in the machining position and has a workpiece main plane oriented perpendicularly to a direction of gravity,
• wherein as the workpiece is arranged in the machining position, the incomplete joint having the course along the separating line which runs in a transverse direction to the workpiece advancing direction is created on the scrap skeleton, which is supported in the direction of gravity by the workpiece support provided as a scrap skeleton support, by separating machining of the scrap skeleton by the scrap skeleton separating device of the shredding device, and
• wherein the deflection device of the shredding device comprises the workpiece advancing device provided as a scrap skeleton advancing device, wherein the scrap skeleton, after the incomplete joint is created, is capable of being moved in the workpiece advancing direction provided as a movement direction of the scrap skeleton with the first scrap skeleton part, which leads in the workpiece advancing direction, beyond the workpiece support into a region in which the first scrap skeleton part is released in the direction of gravity for deflection under the action of gravity, and wherein the released first scrap skeleton part is deflected in the direction of gravity in relation to the second scrap skeleton part, which remains on the workpiece support, under the action of gravity in such a way that the residual connection between the first scrap skeleton part and the second scrap skeleton part breaks, thereby the first scrap skeleton part is separated from the second scrap skeleton part.
