PROBLEM TO BE SOLVED: To solve the problems that when a product is powder, since a worker recognizes the presence or absence of a hole by hitting the upper sides of the products placed on and orderly conveyed by a belt conveyor and observing with eyes whether or not there is scatter of the powder, the worker may happen to overlook the scatter of the powder, and that it is difficult to recognize the presence or absence of the hole on the downward surface in contact with the belt conveyor. SOLUTION: A device includes conveyance lines 3, 11 on which the powder-filled products (w) are orderly conveyed, a suction passage 31 having a suction opening 33 facing to the conveyed products, a fan motor 35 sucking air through the suction opening 33 into the suction passage 31, an infrared sensor 43 detecting the powder (p) passing the suction passage 31 together with the sucked air, and a warning buzzer 61 and a warning lamp 63 both operated on the detection of the powder (p). Therefore, the presence or absence of the hole of the bag is continuously and mechanically detected with this device. COPYRIGHT: (C)2010,JPO&INPIT
