<p>PURPOSE:To enable to stop a pallet with a least shock by a means wherein a first transfer, effected by a belt-conveyor, and a second transfer, effected by a moving magnetic field of a magnetic circuit, is combined so as to generate a thrust in a direction in reverse to the direction of a thrust for a pallet being casued by the moving magnetic field. CONSTITUTION:A pallet 4 is transferred by belt-conveyors 1a, 1b while is stopped by a stopping means 12, and predetermined works and processes for goods on the pallet 4 are carried out during those operations. When an electric source switch SW is closed, respective coils 6b1, 6b2, 6b1', 6b2' in a primary side are fed and a 2' and main coils 6b1, 6b1' is caused by a capacitor C1, a thrust in a direction shown by an arrow sign is generated on a stroke b2 and the pallet 4 is transferred. Thereafter, when the pallet 4 is detected by an photoelectric device 16, a contact of a relay-switch RL2 is switched, the pallet 4 is braked due to an opposite-phase moving magnetic field generated in the primary side of the stroke b2 and is stopped at a notched portion 8 of the moving magnetic field.</p> |
