It is rotatably provided by 5 and opens and closes the upper end of the cylindrical body 12. A primary suction hose 22 for sucking the collected material together with air and a secondary suction hose 24 connecting the tank 10 and the blower are connected to the upper lid 14. The connecting portion between the two suction hoses 22 and 24 is shown in FIG.
As shown in (A), they are juxtaposed on the planar upper lid 14 so as to stand upright on the plane. Therefore, the air introduced from the primary suction hose 22 into the tank 10 is
It is reversed within 0 and discharged to the secondary suction hose 24. As a connecting means for the suction hoses 22 and 24, a quick-changeable one-touch type pipe joint is used.
In addition, exhaust air is introduced into the upper lid 14 so that the exhaust air discharged from the air cylinder device 26 when the air cylinder device 26 operates can be introduced into the tank 10 through the compressed air switching valve. The hose 28 is connected.

Reference numeral 30 denotes a magnetic sensor, which is provided on the peripheral side wall of the cylindrical body 12 of the tank 10 so as to face the inside of the tank 10. The magnetic sensor 30 is a kind of non-contact type sensor and can detect the presence of a metal substance by the action of magnetism. As a result, it is possible to detect that the scrap or the like generated by the metal press working is stored in the tank 10 in a predetermined amount or more. The magnetic sensor 30 is mounted on the peripheral side wall portion of the cylindrical body 12 so as to face the inside of the cylindrical body 12, but the sensor portion is arranged so as not to project inside the cylindrical body 12. For this reason, the inner cylinder 20 can be preferably fitted into the cylindrical body 12, and the sensor portion of the magnetic sensor 30 is in a state of being covered by the inner cylinder 20, so that it does not contact the collected material. This eliminates the need for the operator to clean the sensor portion of the magnetic sensor 30 when performing a setup change or the like. The exhaust air introducing hose 28 is connected to the upper lid 14 at the position of the magnetic sensor 30 so that the exhaust air is blown to the inner surface of the inner cylinder 20 corresponding to the sensor portion of the magnetic sensor 30. There is.

The air cylinder device 26 includes a shaft 3 fixed to the cylinder 12 at the tip of the cylinder.
It is provided so as to be rotatable around 4.

FIG. 3 shows the entire system of the recovery apparatus according to the embodiment shown in FIGS. 1 and 2. Reference numeral 50 denotes a switching valve device, which operates compressed air (arrow A) from a compressed air source by a supply pipe 51 by operating a lever (not shown) to a port 36 on the front end side of the air cylinder device 26 or a rear end side. The communication state of the conduit can be changed so as to supply the port 38 of the above. When this compressed air is supplied to either the port 36 on the front end side or the port 38 on the rear end side, the compressed air is discharged from the port on the side where the compressed air is not introduced. The discharged air is introduced into the cylindrical body 12 by the compressed air introducing hose 28 via the switching valve device 50. At this time, the exhaust air is guided so as to be blown to the inner surface of the inner cylinder 20 corresponding to the magnetic sensor 30, and blows off the collected collected matter. Thereby, the surface of the inner cylinder 20 is preferably cleaned every time the lower lid 16 is opened and closed. Therefore, particularly when collecting the same type of scrap, the worker can continuously collect the scrap without cleaning the inside of the sensor and the cylinder 12.

Reference numeral 40 is a blower, which is a blower capable of generating a predetermined negative pressure and air volume so that the collected matter can be sucked together with air. Reference numeral 60 denotes a recovery container, which is located below the tank 10 so as to receive the scrap collected by the tank 10. In addition,
