Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of retail devices, in particular to a coin sorting and change device. BACKGROUND

[0002] In China, there are three different denominations of coins, namely one angle, five angles and one yuan, and the sizes of the coins of the three denominations are different. The coins need to be classified according to the denominations. The coin sorting and change device is a device that classifies and stores coins of different denominations, and selects appropriate coin combinations from the sorted coins according to a preset change amount to accurately output the required coins for change.

[0003] At present, the existing coin sorting and change device usually classifies coins by sliding the coins on an inclined chute. The chute is provided with a plurality of sorting holes of different sizes. Different denominations of coins are dropped into the corresponding money box after sliding to the corresponding sorting hole, thereby completing the classification of the coins. However, the surface of the chute usually has small protrusions or depressions. The coins are easily rubbed with these uneven parts during sliding. When the friction is large, the coins may stop on the chute and form a coin sticking phenomenon, which hinders the normal passing of subsequent coins. At the same time, the coins slide on the inclined chute by their own gravity. When there are too many coins or the sliding speed of the coins is too fast, the coins are easily squeezed and stacked at the sorting hole, causing a coin jam phenomenon, thereby interrupting the coin sorting process.

[0004] Therefore, the traditional coin sorting and change device is prone to the phenomena of coin sticking and coin jamming, which seriously hinders the smooth progress of the coin sorting process, reduces the efficiency of coin sorting, and has obvious disadvantages. CONTENT OF THE INVENTION

[0038] With reference to Figure 1 , Figure 2 and Figure 3 , a plurality of money boxes 5 are fixedly installed inside the box body 1, and in this embodiment, the number of money boxes 5 is three, and the three money boxes 5 are respectively used for storing one-angle, five-angle and one yuan coins. The box body 1 is provided with a coin inlet 102 corresponding to each of the plurality of money boxes 5, and the caliber of the coin inlet 102 gradually increases along the conveying direction of the coin chute 3. The plurality of coin inlets 102 are in communication with the coin chute 3, and the inner walls of the coin chute 3 and the plurality of money boxes 5 are coated with a polytetrafluoroethylene coating. The polytetrafluoroethylene has a very low friction coefficient, which makes the sliding of the coins in the coin chute 3 and the money boxes 5 more smooth, and reduces the probability of problems such as coin jamming or slow movement of the coins caused by friction resistance.
