にできないなどの欠点があつた。 Conventionally, a workpiece delivery device is installed on a stack station that stacks workpieces on pallets so that it can be raised and lowered, and the workpieces are transported to the upper part of the pallet by a carrier, are attracted to the workpiece delivery device at a certain height, and are lowered down. The workpieces are then released on the pallet, but if the workpieces are not released after detecting that they have come into contact with the pallet, the workpieces will be misaligned and will not be stacked correctly. Therefore, a device was used to detect contact with the pallet as an electric circuit, but
In recent years, wooden pallets have been adopted in order to save costs, but this has had the disadvantage of not being compatible. There is also a device that detects contact with the pallet without using an electric circuit and uses the signal to cause the suction device to adsorb or release the pallet, but if the suction device is a vacuum cup, there is a delay in operation, and if the suction device is a permanent magnet, there is a delay in the operation. Since they are released by dropping, they have the disadvantage that they cannot be stacked accurately.

実施例について図面を参照して説明する。 The purpose of the present invention is to eliminate these drawbacks, and to raise the adsorption member using a permanent magnet above the side plate in response to a signal from contact with the workpiece, and release the workpiece while it is held on the pallet by the side plate. To provide a workpiece delivery device which allows accurate stacking and prevents the stacked works from collapsing. Embodiments of the present invention will be described below with reference to the drawings.

The top surface of the piston 5 has the piston 5
An eccentric pin 11 is erected from the center of the piston 4, and is fitted into a hole in the main body 4 so as to be able to move up and down, and prevents the piston 5 and the workpiece suction member 8 connected thereto from rotating. The cavity above the eccentric pin 11 is connected to the atmosphere by a hole 12. Side plates 13, 13 are provided on both sides of the workpiece adsorption member 8, and the upper ends of the side plates 13, 13 are movable up and down on the main body 4, are prevented from coming off downward, and are fixed to a cylindrical member 14 whose upper limit is regulated.

When piston rod 2 and piston rod 2 are at the upper limit,
Compressed air is supplied from the supply/discharge port 9, exhaust is exhausted from the supply/discharge port 10, and the piston 5 and the work adsorption member 8 connected thereto are at the lower limit as shown in the figure. In this state, the workpiece 3 is attracted to the permanent magnet 7 and is lowered together with the receiving piston rod 2 to press the workpiece 3 onto a pallet (not shown).
Then, the side plates 13, 13 compress the spring 15 through the cylindrical member 14 and rise, and the workpiece adsorption member 8 overcomes the biasing force of the compressed air of the piston 5 and rises. When the sensor plate 17 fixed to the cylindrical member 14 approaches or comes into contact with the operating distance of the proximity switch 16, a signal is output from the proximity switch 16, and that signal causes the supply/discharge port 10 to open to the supply air. , the supply/discharge port 9 is switched to exhaust. Therefore, when the piston 5 rises and the workpiece adsorption member 8 rises accordingly, the lower surface of the permanent magnet 7 rises above the lower surface of the side plate 13 whose upper limit is regulated by the force of the spring 15, and the workpiece 3 is lifted away from the permanent magnet 7. The workpiece 3 is released. Subsequently, the workpiece transfer device 1 moves up together with the piston rod 2, and when the cylindrical member 14 falls under the force of the spring 15, the sensor plate 17 separates from the proximity switch 16 and the signal output of the proximity switch 16 stops.

置ずれを起すことなく正確に積み重ねられる。 The stop signal switches the supply/discharge port 9 to supply air and the supply/discharge port 10 to exhaust air. By repeating the above steps, the works 3 are stacked on the pallet. Since the works 3 are pressed onto the pallet and released, they can be accurately stacked without any displacement.

の効果と利点は大きい。 As is clear from the above description, according to the present invention, the work suction member separates from the work and releases it while the work is held down by the side plate, so that the work can be stacked accurately with high alignment accuracy without causing positional deviation. It has great practical effects and advantages, such as ensuring the safety of workers without worrying about the loads falling apart due to poor stacking.
