Description

one

The invention relates to devices for sorting money according to the merit of money and is intended for use in transport enterprises, trade enterprises, and public utilities in sorting coins by diameter. The invention can also be used to sort by the diameter of any flat objects, such as washers, disks, etc.

A device for sorting coins by diameter is known, comprising a hopper for loading coins, a mechanism for feeding coins for sorting, a coin duct, and a separating mechanism. The dividing mechanism is made in the form of an inclined slat with holes for the passage of the sorting of washed coins. The coins move along the rack under the force of gravity. The number of holes in the rail corresponds to the number of sizes of sorted coins. Through the holes of the coin, under the influence of gravity, they fall into the compartments of the cassette for collecting coins 1.

In this device, the construction of the split-one mechanism does not provide high performance. With an increase in the speed of movement, the coins pass by their intended openings, which reduces the sorting accuracy.

Closest to the present invention is a device for sorting coins containing a hopper with a coin feeding mechanism and a flow former connected through a coin duct to a separating mechanism consisting of a channel with successive openings and mounted above the conveyor channel. and intermediate rollers 2.

The disadvantage of this device is that when moving along the channel the coins repeatedly collide with a device to reduce the width of the channel and change their trajectory, which leads to a decrease in the speed of their movement and does not allow to obtain high sorting performance. Another disadvantage of this device is the need to install additional devices on each stream.

0 sorted moments in order to create an oriented movement of coins for their further processing (counting, sorting by alloy, etc.). The purpose of the invention is to increase productivity and sorting accuracy. The goal is achieved by the fact that in the device for sorting coins, the channel of the separation mechanism is curved, and the holes of the channel are shaped as slots whose working surface is tangential to the working surface of the channel. The axes of the intermediate rollers are equidistant from the working surface of the channel of the separation mechanism. FIG. 1 shows the device, a general view; in fig. 2 - the same, longitudinal section; in fig. 3 - channel separation mechanism, top view; in fig. 4 shows section A-A in FIG. 2. A device for sorting coins comprises a hopper 1 for loading coins, mounted above the coin feeding mechanism 2 for sorting and a coin line 3, which connects the coin feeding mechanism 2 and a separating mechanism, the latter consisting of a channel 4 and a conveyor 5. A coin feeding mechanism 2 the sorting is made in the form of a rotating disk 6, along the perimeter of which a fixed fence 7 is mounted. A rotating flow driver 8 (with a gap allowing the coins to pass in one layer) is fixed above the rotating disk 6. The coinpipe 3 is made in the form of a tray mounted between the feed mechanism 2 and the separating mechanism. Channel 4 of the separation mechanism is curved and has a fence 9. On the working surface 10 of channel 4 there are holes 11 in a sequence from a smaller size to a larger one. The holes 11 are made in the form of slots, the width of which corresponds to the diameters of the sorted coins, and the height - their thickness. The number of holes 11 corresponds to the number of sizes of sorted coins. One of the edges of the holes 11 lies in the same plane with the working surface of the fence 9. The radius of curvature of the channel 4 is determined by the dimensions of the device, the height of the slit and must ensure the minimum resistance to the flow of coins. The working surfaces 12 of the holes 11 are made tangentially to the working surface 10 of the channel 4. The conveyor 5 is mounted above the channel 4. It contains a belt 13 tensioned on the end rollers 14 and 15 (one of them leading), and intermediate rollers 16, whose axes are spring-loaded and provided with constraints (not shown in the drawing). Conveyor 5 is mounted above channel 4 with a gap protecting belt 13 from rubbing against working surface 10 of channel 4 Intermediate rollers 16 are mounted above holes 11 of channel 4. Working surfaces 12 of holes 11 smoothly pass into guides 17. Under channel 4 of the separating mechanism devices for separating coins by alloy, for counting coins and a cassette with compartments for receiving sorted coins can be placed. The mechanism 2 feeding coins for sorting and the drive roller of the conveyor 5 are driven by an engine. The device works as follows. The coins are loaded into the hopper 1, from which they enter the central part of the rotating disk 6. Under the action of the centrifugal force, the coins are thrown to the disk periphery and distributed by means of the device 8 in series and in one layer. Then the coins are moved along the coin conduit 3 to channel 4. When the flow of coins moves through channel 4, the smaller one passes into the first hole 11 in the flow path corresponding to its size, and along the working surface 12 and guide 17 enters further processing. Larger coins of the conveyor belt 13 with the conveyor 5 are pulled along the channel 4 to the holes 11 that correspond to their sizes. At the same time, the coins whose diameter is larger than the width of the hole 11 over which they are drawn support: it lives on the working surface 10 of channel 4 (see Fig. 4) tape 13 for one side. The intermediate rollers 16 corresponding to these holes are pressed onto the coins. Such support of the coin for one edge prevents the coin from colliding with the upper edge of the hole P. When the coins pass under the intermediate rollers 16 along the latter are raised by spring-loaded axles. The centrifugal force that occurs when coins are moved along the working surface 10 of channel 4 ensures that the coins come out of the surface 10 along the tangent into the hole 11. Coins entering the hole 11 do not change their direction of movement and along the guides 17 they are further processed ( counting, sorting by alloy, etc.), and then into the compartments of the coin collection cassette. The design of the separation mechanism ensures unhindered collection of coins for further processing and in the compartment of the coin collecting cassette, which allows a greater sorting speed to be developed. In addition, a strictly directed stream of coins is provided in the device without the installation of additional devices.
