Start light-duty bunching device 2000, light-duty bunching device 2000 moves to pile up a pile station in advance and carries out the prestack:

the light gripping device 2400 is run to the beginning of the end of the belt transfer device 4100.

The left embracing mechanism 2430 and the right embracing mechanism 2440 of the light-duty gripping device 2400 embrace the supporting plate containing the magnetic blank at the starting point, the light-duty gripping device 2400 supports the supporting plate containing the magnetic blank to ascend, transversely moves to the position right above the transfer table to descend, stops descending after a pressure sensor receives a signal, and releases the left and right embracing mechanisms. The light-weight gripper 2400 is raised again, moved laterally right above the starting point and lowered to the starting point, (at this point, another pallet to be stacked containing magnetic blanks has also been transferred to the starting point), and the light-weight gripper 2400 repeats the above actions. Until stacked to the desired height on the transfer table. The light stacker 2000 is moved longitudinally a distance to give way to the heavy stacker.

In the pre-stacking process, manual intervention is allowed, automatic operation is suspended, and even manual control is changed, so that the height of the supporting cushion block is manually adjusted to ensure the stability of stacking.

The heavy stacker 3000 is started, and the heavy gripping device of the heavy stacker 3000 moves to the position of the transfer table, so that the position and the height are adjusted. The movable transverse plate 3450 is inserted into the lower ends of the left arm and the right arm of the heavy-duty grabbing device, the heavy-duty grabbing device is lifted, and all the supporting plate groups filled with the magnetic blanks at the pre-stacking station are lifted at one time. The heavy-duty gripping device continues to move transversely and longitudinally to a proper position of the small furnace car 5000, slowly descends until the supporting plate group filled with the magnetic blanks is stacked on the small furnace car 5000, stops moving, manually and laterally extracts the movable transverse plate 3450, and rises and transversely moves to a station to be worked for pausing to wait for the next operation.

The trolley 5000 can also be displaced longitudinally intermittently (longitudinal guides are provided on the ground, not shown in the drawings, which are already existing structures used in the production, but only manual stacking), in order to cooperate with the stacking of heavy-duty stacking devices.

After the heavy stacker removes all the groups of pallets loaded with magnetic blanks at the pre-stacking station at one time, the light stacker 2000 may continue the pre-stacking at the pre-stacking station.

The above work is repeated until all the stacks on the small furnace car are finished.

The magnetic material blank stacking equipment has the characteristics that:

the light stacking device is adopted to stack the supporting plates filled with the magnetic blanks into the supporting plate group with a certain height at the pre-stacking station, so that the moving path of the light gripping device is reduced, and the work efficiency is improved conveniently.

The operator is in fixed point position cooperation prestack, adjusts the height of lip block etc. and sparingly personnel's physical power.

The heavy stacking device is adopted to move the supporting plate group filled with the magnetic blanks in place at one time, so that the working efficiency is improved.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
