An automatic jewel counting device

Abstract

The invention discloses an automatic gem counter. A raw material tank with strip-typed discharge holes on the bottom, a partition plate arranged below the raw material tank and facing with the strip-typed discharge holes and a collecting device arranged below the partitioning plate are fixed on a rack, driving devices, a transmission device and a counting mechanism are further arranged on the rack, the counting mechanism comprises a counting plate and a sensor which are arranged between the raw material tank and the partitioning plate, the driving device is in linkage with the counting plate via the transmission device, a plurality of rows of counting holes is arranged on the counting plate and are covered by the partitioning plate and can be separated from the covering of the partitioning plate during the movement of the counting plate, and the counting holes of each row correspond to the strip-typed discharge holes when covered by the partitioning plate, each counting hole in each row corresponds to one sensor respectively when moving to the edge of the partitioning plate, and further, corresponds to the collecting devices when separating from the covering of the partitioning plate. The automatic gem counter is time saving and energy saving, high in efficiency, rapid, efficient, accurate and free of light pollution.

Description

technical field [0001] The invention relates to a counting device, in particular to an automatic jewel counting device. Background technique [0002] Counters that serve as gem counts play an increasingly important role in gem trading. According to the market survey, the gemstones currently on the market are counted manually under the glare of the light, using a small counting board to count the particles of the gemstones. If the average daily trading volume of the market is 15 million, the cost of manual counting is required. It is 60 yuan per person per day. In the case of 8 hours of normal work, each person can count up to 100,000 pieces per day. Not only the efficiency and accuracy of the counting are relatively low, but also the labor intensity is high, and the light reflected by the gemstones has a long time Human eyes can cause some damage. Contents of the invention [0003] The object of the present invention is to provide an automatic gemstone counting device th...
