IPC: B65B1/06
Filed: 1987-05-15
Abstract: PURPOSE:To prevent the erroneous detection of a bag and the lowering of operational efficiency by providing light sensing means secured to the two side surfaces facing each other of a discharge outlet portion and a discharge initiating means to discharge grains upon reduction of the amount of light received by the light sensing means when the discharge outlet portion is inserted in a bag. CONSTITUTION:A discharge outlet portion 33 is inserted by a fork 34 from an opening portion of an expanded unhulled rice bag 2 into the interior thereof. The fork 34 is provided with fork sensors S3 and S4 at its front and rear ends. The front and rear fork sensors S3 and S4 receive external light by the light sensing means. Upon insertion of the fork sensors S3 and S4 into the unhulled rice bag 2, the external light is intercepted by the unhulled rice bag 2, resulting in a reduction in the amount of received light. It can be judged, therefore, that the discharge outlet portion 33 has been inserted into the interior of the unhulled rice bag 2 when the amount of light received by both the front and rear fork sensors S3 and S4 are reduced. Upon reduction of the amounts of light received by the fork sensors S3 and S4, the forward rotation of a chain motor M1 continues until an actuator 52 reaches a terminal position P2. The actuator 52 engages with an opening and closing portion 54 of a shutter to release the shutter 32 for discharging the grains.
