Coin sorting and counting device

Abstract

The invention relates to a coin sorting and counting device which is composed of a power screening module, a coin sorting module, a counting module, and a coin storing module. In the power screening module, the diameter of a coin outlet is slightly greater than that of a one-yuan coin, screening baffles are installed on a coin shaking box, and when a DC motor is working, a cam is driven to rotate, the coin shaking box shakes, and coins are screened out. In the coin sorting module, after coins are screened from the coin shaking box, the coins fall into a coin slide under the action of gravity, slide into a T-shaped baffle via the coin slide and roll along a coin rolling track in an accelerated way, and three different wedge blocks are installed on an inclined plate to isolate one-yuan coins, five-jiao coins and one-jiao coins in sequence. The counting module is equipped with three counter probes. The coin storing module is provided with corresponding coin storing hoppers, and each coin storing hopper is used for collecting coins of a different currency value. The device can be used to screen a variety of coins, has a simple structure, and is of low cost.

Description

technical field [0001] The invention relates to the technical field of coin sorting and counting, in particular to a small coin sorting and counting device for sorting and sieving coins according to their diameters. Background technique [0002] Coins are often used as a form of small denomination currency, and are often used in daily activities such as shopping for change, taking public transportation, and using amusement facilities. Although coins are easy to use, it is not easy to sort and count a large number of coins for the staff of units such as banks and bus companies that need to handle a large amount of coins. At present, the work of sorting and sorting coins is mostly done manually, with heavy workload, boring content and low efficiency. One way to solve this problem is to use automated coin sorting and counting devices.

Problems solved by technology

[0003] Among the related patents disclosed in the prior art, the patent "A Mechanical Coin Sorter and Its Application Method" (Patent No.: ZL201510790042.4) utilizes the rotation of a columnar cam to sort coins, and through incomplete gears and racks The meshing to control the movement of the coin storage box to collect coins, the structure is simple, but the efficiency is low; the patent "coin sorting counter" (patent number: ZL201520052160.0) uses a single-chip photoelectric sensor to count the coins, through the bucket switch knob and the motor conveyor belt Control the coins into different coin receiving cylinders, the counting is accurate, but the automatic separation of coins cannot be realized, and the knob needs to be turned manually; the patented "coin sorting machine" (patent number: ZL201510378178.4) relies on the weight of the coins to classify the coins, and passes through the sorting chute Control coins fall into the corresponding coin collection tube, but does not involve the counting of coins; the patent "coin sorting output device" (patent number: ZL201220691229.0) uses a coin recognizer to identify coins, and controls the coins to fall into the designated storage through the control system. Currency warehouse, powerful function, but high cost
