An apparatus for handling sheets and the operating method thereof is disclosed, the apparatus including: a handling unit for gripping and transferring sheets to and from a sheet change support with a substantially horizontal attitude; and a receiving-transmitting electromagnetic beam unit which generate electromagnetic beams arranged on a plane which is intercepted by the sheets when they take up an attitude at least partially different from the horizontal one. The receiving-transmitting electromagnetic beam unit is fixedly arranged on at least a couple of linear bars arranged at the same height for generating a horizontal-mesh barrier, consisting of intersecting, stationary electromagnetic beams, generated by the receiving-transmitting unit, the barrier being defined above an area occupied by the sheet change support.

The invention relates to a transport apparatus (10) for the collision-free loading and unloading of a material machining unit (1) with a workpiece (5) comprising a guide apparatus (60), a plurality of transport devices (15, 16, 17, 18), wherein one of the transport devices (15) is arranged on a first transport device level (20), as well as another transport device (16) being arranged on another transport device level (21). A multifunctional tooling apparatus (25) for transporting and/or machining the workpiece (5) or the workpiece part is arranged on the transport device (15). Furthermore, the invention relates to a method for loading and unloading the material machining unit (1) using such a transport apparatus (10), as well as a computer program product for loading and unloading according to this method and using such a transport device (10).

A manufacturing apparatus for heat dissipation fins can stably operate a stacker apparatus when stacking and collecting heat dissipation fins. Drop guide blades are provided above a holding apparatus for the heat dissipation fins disposed downstream of a cutoff apparatus that cuts a heat dissipation fin molding formed by a press apparatus into heat dissipation fins. When a stacker apparatus receives a heat dissipation fin from the holding apparatus, the drop guide blades approach the stacker apparatus and the heat dissipation fin is stacked and collected in the stacker apparatus by dropping to the stacker apparatus while being guided by the drop guide blades. After collecting the heat dissipation fins, only lowering operations of the stacker apparatus are performed.

A bending robot takes out a workpiece stored on a stacker while contacting its end face with a storage reference flat plane of the stacker, and then supplies it to a bending machine. The bending robot includes a main body movable parallel to the storage reference flat plane, an arm portion supported by the main body and capable of positioning above the stacker, and a distance sensor provided in the arm portion for measuring a distance to the workpiece stored on the stacker in a contactless manner. According to the bending robot, bending can be done with high efficiency.
