Abstract

A coin dispensing cylinder relates to the field of automatic screening, especially the sorting of coins of different denominations. Utility model patent coin box, patent number 200420037860.4, easy to choose by mistake. In order to overcome the deficiency of misselection in the coin box, the present invention designs a coin tube. The technical scheme is: the coins that come in from the coin hole enter the ramp, the ramp is spiral, the helix is at least 360 degrees, the ramp is inclined towards the direction of the outer barrel, the ramp and the horizontal plane form an angle of 45 degrees, and the coin hole is along the The outer cylinder is opened, and there are multiple coin holes for each currency value. The diameters of the coin holes are 20mm, 21-22mm, and 23-24mm in turn. The final exit is the currency value of 1 yuan. There is a coin-taking hole and 4 coin-collecting boxes, each occupying 1/4 of the outer barrel area. Beneficial effects: the inclined ramp greatly reduces the risk of wrong coins; the spiral ramp prolongs the falling length, slows down the falling speed, and reduces the risk of wrong coins due to inertia.

Description

a coin barrel

technical field

The invention relates to the field of automatic screening, in particular to the classification of coins of different currency values.

Background technique

The utility model patent coin box, patent number 200420037860.4, is used to automatically classify coins of 1 cent, 5 cents and 1 yuan. The problem is that there is only one screening hole for each currency value. Since coins of various currency values enter together, therefore The channel must be at least 1 yuan to be able to pass through, so the natural channel should be wider than the 1 yuan coin, then the 1 jiao or 5 jiao coin may pass through the leak under the inertia of a certain sliding speed because it is not completely aligned with the coin hole. Coin hole, enter the leaking coin hole of the next currency value, resulting in wrong selection.

Contents of the invention

In order to overcome the deficiency of misselection in the coin box, the present invention designs a coin tube.

The technical solution adopted by the present invention to solve the technical problem is: the coin separating cylinder is made up of an inner cylinder, an outer cylinder, a ramp, a coin slot, a leaking coin hole and a coin collection box.

The inner cylinder has a cover, and an annular cover with a coin-operating hole is arranged between the inner cylinder and the outer cylinder, and the inner cylinder cover and the annular cover with the coin-operating hole can form an integral structure.

Coins coming in from the coin hole enter the ramp. The ramp is spiral, with a helix of at least 360 degrees. The falling presents a circular motion, and under the action of centrifugal force, the coins must move against the outer barrel; due to the inclination of the ramp, the coins must also move along the outer barrel under the action of the component force of gravity.

Slip holes are opened along the outer cylinder, and there are multiple slip holes for each denomination. To enhance the effectiveness, the slip holes for each denomination are about 1mm smaller than the diameter of the next denomination, so the diameters of the slip holes are 20mm in turn. , 21-22mm, 23-24mm, the final export is the currency value of 1 yuan, there is no need to set the coin hole.

The coin collection box has a coin-taking hole, and the door of the coin-taking hole is opened to take out coins.

There are 4 coin collecting boxes, each occupying 1/4 of the outer barrel area.

Beneficial effects of the present invention: the inclined ramp can effectively sort coins, greatly reducing the risk of misplaced coins; the spiral ramp prolongs the falling length, increases the friction time, slows down the falling speed, and reduces the risk of misplaced coins due to inertia. The height difference of one circle of spiral controls the speed of coin falling.

Detailed ways

The coin-separating cylinder is made up of inner cylinder 1, outer cylinder 2, ramp 3, leaking coin hole 4 and coin collection box 5.

The inner tube 1 has a cover, and an annular cover with a coin hole is arranged between the inner tube 1 and the outer tube 2, and the inner tube cover and the ring cover with the coin hole can form an integral structure.

Coins coming in from the coin hole enter the ramp 3, the ramp is inclined towards the direction of the outer barrel, the ramp is at an angle of 45 degrees to the horizontal plane, the ramp is arranged along the cylinder, and the falling of the coin presents a circular motion. The outer barrel moves; due to the inclination of the ramp, the coins must also move along the outer barrel under the action of the component force of gravity; the coin slip hole is set along the outer barrel, to enhance the effective type, the coin slip hole of each currency value is 4 more than the next one The diameter of the currency value is about 1mm smaller. Considering the fourth set of RMB and the fifth set of famous coins, the diameter of 1 yuan is 25mm, the pentagon is 20.5mm, the fourth set is 22.5mm, and the fifth set is 19mm. Therefore, the diameter of the leaking hole is set It is: 21-22mm for the pentagon, 23-24mm for the fourth set, 23-24mm for the fifth set, 20mm for the fifth set, and the currency value of 1 yuan for the final export, and there is no need to set the coin hole. Therefore the diameter of coin hole is 20mm, 21-22mm, 23-24mm successively.

The sorted coins enter the coin collection box 5.

The coin collection box has a coin-taking hole 6, and the door of the coin-taking hole is opened to take out coins.
