Abstract:
1. A device for detecting weight of capsules, comprising a hopper having a top opening and a bottom opening, a vertical upper passageway having a top opening and a lower end, the top opening of the upper passageway cooperating with the bottom opening of the hopper for receiving capsules, a discharge gate at the lower end of the upper passageway having two sides, a main shaft driven by a motor, a transport wheel disposed on the main shaft and positioned at one side of the discharge gate having at least one storage chamber at its perimeter, a pushing structure positioned at the other side of the discharge gate and being capable of extending into the discharge gate and pushing the capsules into the storage chamber, a first cam disposed on the main shaft for driving the pushing structure, a discharging structure for pushing the capsules out of the storage chamber, a second cam disposed on the main shaft for driving the discharging structure, a weighting platform below the transport wheel for accepting and weighing the capsules out of the storage chamber, and a lower passageway, wherein the pushing structure has a first idler wheel, the first cam is an irregular plate having concave parts and convex parts, and the concave parts of the first cam coordinate with the first idler wheel for pushing the capsules into the storage chamber; and the discharging structure has a second idler wheel, the second cam is an irregular plate having concave parts and convex parts, and the concave parts of the second cam coordinate with the second idler wheel for discharging the capsules from the storage chamber.
