Claims
- 1. A quantitatively supplying apparatus, which comprises:
- a weighing bucket having a discharge mechanism at a bottom portion thereof;
- a load cell for detecting the weight of said weighing bucket;
- a transferring conveyor for continuously supplying goods to said weighing bucket in a dispersed and scattered condition;
- a falling zone formed between the transferring conveyor and said weighing bucket;
- means positioned in said falling zone for guiding goods from said transferring conveyor to said weighing bucket;
- at least one shutter arranged between said weighing bucket and said transferring conveyor; and
- means for moving said at least one shutter into and out of the falling zone in response to the weight of goods which have fallen into said weighing bucket detected by said load cell and for partially stopping falling of the goods in said dispersed and scatted condition through said falling zone when the weight of the goods in said weighing bucket reaches a first predetermined weight and more completely stopping falling of the goods in said dispersed and scattered condition though the falling zone upon reaching a second predetermined weight so as to increase weighing accuracy of said weighing bucket wherein said at least one shutter is positioned in said falling zone and receives said goods dropped from said transferring conveyor when said load cell detects a predetermined weight of goods said in weighing bucket.
- 2. A quantitatively supplying apparatus as set forth in claim 1, wherein said at least one shutter comprises a first and second shutter movable towards and away from one another in response to the weight of goods in said weighing bucket detected by said load cell.
- 3. An apparatus as set forth in claim 1, which comprises means for regulating the vertical position of the at least one shutter so as to change the vertical distance between at the least one shutter and the bottom of said weighing bucket.
- 4. A quantitatively supplying apparatus, which comprises:
- a weighing bucket having a discharge mechanism at a bottom portion thereof;
- a load cell for detecting the weight of said weighing bucket;
- a transferring conveyor for continuously supplying goods to said weighing bucket in a dispersed and scattered condition;
- a falling zone formed between the transferring conveyor and said weighing bucket;
- means position in said falling zone for guiding the goods from said transferring conveyor to said weighing bucket;
- at least one shutter arranged between said weighing bucket and said transferring conveyor;
- means for moving said at least one shutter into and out of said falling zone in response to the weight of goods in said weighing bucket detected by said load cell and for partially stopping falling of the goods in said dispersed and scattered condition through the falling zone when the weight of goods in said weighing bucket reaches a first predetermined weight and for more completely stopping falling of the goods in said dispersed and scattered condition through the falling zone upon reaching a second predetermined weight so as to increase weighing accuracy of said weighing bucket wherein said at least one shutter is positioned in said falling zone and receives said goods dropped from said transferring conveyor when said load cell detects a predetermined weight of goods in said weighing bucket; and
- means for slowing the traveling speed of said transferring conveyor after said load cell detects a predetermined weight smaller than said given weight.
- 5. An apparatus as set forth in claim 4, which comprises means for regulating the vertical position of the at least one shutter so as to change the vertical distance between the at least one shutter and the bottom of said weighing bucket.
- 6. A quantitatively supplying apparatus which comprises a weighing bucket having a discharge mechanism at the bottom and first and second sidewalls forming a lattice, a load cell for detecting the weight of said weighing bucket, a transferring conveyor for supplying goods to said weighing bucket, and first and second shutters positioned independent of said weighing bucket so as to extend through said first and second sidewalls of said weighing bucket and so as to be movable towards and away from one another and which partially close a goods drop passage leading from said transferring conveyor to said weighing bucket when said load cell detects a predetermined weight of goods in said weighing bucket.
- 7. An apparatus, as set forth in claim 6, which comprises means for slowing the traveling speed of said transferring conveyor after said given weight is detected.
- 8. An apparatus, as set forth in claim 6, which comprises means for completely closing said shutters when said load cell detects a weight to be finally weighed.
- 9. An apparatus, as set forth in claim 6, which further comprises means for regulating the distance from the shutters to the bottom of said weighing bucket can be regulated.
