Abstract
A dropping device, system and filling method. The dropping device includes a feeding port provided on an upper side of a dropping chute and configured to receive an object to be dropped; a first side wall extending from an edge of the feeding port in a direction deviated from a vertical direction by a first angle; and a second side wall disposed opposite to the first side wall and extending from an edge of the feeding port in a direction deviated from the vertical direction by a second angle. The second angle being greater than the first angle. A discharging port is provided on a lower side of the dropping device and configured to discharge the object.
Claims14
A dropping device comprising:
- a feeding port provided on an upper side of the dropping device and configured to receive an object;
- a first side wall extending from an edge of the feeding port in a direction deviated from a vertical direction by a first angle;
- a second side wall disposed opposite to the first side wall and extending from the edge of the feeding port in a direction deviated from the vertical direction by a second angle, the second angle being greater than the first angle;
- and
- a discharging port provided on a lower side of the dropping device and configured to discharge the object from the dropping device.
A filling method comprising:
- receiving an object to be filled into a container;
- converting a falling posture of the object from a first posture to a second posture by using a dropping device;
- wherein the dropping device comprises a movable plate, the movable plate constituting a portion of a second side wall of the dropping device close to a discharging port of the dropping device,
- wherein converting the falling posture of the object from the first posture to the second posture by using the dropping device comprises:
- moving the movable plate at a frequency greater than a frequency of dropping the object;
- moving the object converted into the second posture into a filling trough,
- wherein a bottom plate of the filling trough is movable and extends downward at a predetermined inclination angle with respect to a horizontal plane along a moving direction of the object;
- and
- in response to receiving a signal indicating that the container reaches below the filling trough, moving the bottom plate to form an opening at a bottom side of the filling trough, so as to cause the object to fall into the container.
