Abstract

The utility model relates to an automatic machine for separating coins. The realization of separating of the utility model is under the action of vibration, and makes the use of the thickness of coins and the interrelation of diameters through the restrictive channel. The automatic counting is carried out by phototube circuit. The utility model can improve job conditions, enhancing work efficiency, automatically and efficaciously completing the separating, counting, stacking, loading in box of coins, and has the advantages of accurate separating and counting.

Description

Automatic machine for separating coins

The utility model is a kind of device that is specially adapted to the go-no-go coin.

At present, when coin mixes, to they classification, count, pack, work such as packing almost is to rely on the relevant personnel to carry out by hand entirely, and is time-consuming bothersome, make mistakes easily, loaded down with trivial details, and unhygienic.

The purpose of this utility model is to design the utensil of the automatic go-no-go coin of a kind of energy, to increase work efficiency.

Automatic coin separating machine mainly is under the effect of vibration, utilizes the mutual difference between coin thickness, diameter, realizes go-no-go by restrictive duct, and the utility model will be further described below in conjunction with accompanying drawing.

It mainly is made up of institutes such as motor (23), transmission device, toggle, coin collecting box (13), guide groove (4) thumb wheel (12), coin dropping hole (6), coin reservoir (24) and photoelectric accounters. Coin collecting box is connected with guide groove, and both are to going out the coin direction. Coin collecting box can be the open-top receptacle of square, circular or other shape, and is jagged with the guide groove junction, and it is to mix the place that coin is put into. Guide groove is the road that transmits coin, and for the benefit of coin down sliding tilts. Thumb wheel is the revolving member of radially uniform 4 blades on the face of cylinder, and blade length is slightly less than the guide groove width, and it is installed in the collection coin Less than 2 times of minimum coin thickness, the effect of thumb wheel is to control coin and only perhaps enters singly guide groove, and overlapping coin is reversed coin collecting box greater than the thickness of largest coins for the joining place of box and guide groove, thumb wheel outer rim and guide groove bottom surface distance b. Motor makes coin collecting box, guide groove vibration by transmission device, toggle, and the band thumb wheel rotates counterclockwise. Transmission device adopts belt pulley to rotate. The guide groove bottom surface has two or more, greater than corresponding coin diameter, and less than the coin dropping hole of contiguous large coins diameter dimension, the coin commonly used such as China has three kinds, then in the guide groove bottom surface by one, two, five-cent piece opens three kinds of coin dropping holes and gets final product, first hole is greater than 1 fen diameter, and less than 2 minutes hole, second hole is greater than 2 minutes, and less than 5 minutes hole, analogize. And coin dropping hole is arranged along the coin direct of travel from small to large successively; Coin reservoir is the cylindrical tube shape container, presses the kind (diameter) of coin and makes, and guarantees to hold the coin of this kind some, and it places under the corresponding coin dropping hole; Whole photoelectric accounter is made up of power supply, light source, control relay circuit sum counter, power supply provides the 6V direct current by transformer and simple voltage stabilizing power supplying circuit for light source and control relay circuit, 6V pea lamp light source and phototriode (3DU) form the photoelectricity door, and the photoelectricity door is installed between coin dropping hole and the coin reservoir. Whenever fall down a coin and just export a pulse, amplify control relay (J) through triode (3DG6,3DG101A), secondary, the contact of relay connects counter, can realize tally function. This device adopts cheap calculator (3) to repack counter into and uses, and manually presses successively calculator

、

Four buttons just can be realized tally function, press

Key resets. The coin that mixes is placed coin collecting box, and under effect of vibration, because coin collecting box and guide groove tilt to install, the coin in the coin collecting box is that Way out moves to lower; Be subjected to the control of thumb wheel, overlapping coin is reversed in the coin collecting box, only allow that coin passes through singly, in guide groove, advance, when through first kind of coin dropping hole, the coin of minimum diameter falls into the hole in edge, hole centre-of gravity shift automatically by gravity, through the effect of photoelectric tube output count signal, counting, minimum diameter hard Coin is fallen in first kind of coin reservoir and is automatically flat folded, and the coin of all the other diameters is then successfully crossed first kind of coin dropping hole, continues to advance. In like manner, arrive from childhood greatly, the coin of second diameter falls into the second coin dropping hole, in the second coin reservoir ..., carry out successively.

Pick with separating one by one for guarantee leaking the coin effect, guide groove is an angle of inclination and groove width laterally to be arranged greater than the largest coins diameter, and less than the u shape strip member of 2 times of minimum coin diameters, and there is above-mentioned coin dropping hole the guide groove bottom surface, and coin is advanced along lower cell wall in guide groove automatically one by one. Coin dropping hole all adopts right-angled trapezium, and its oblique waist limit is positioned at the coin upstream end, and two bases are parallel with the coin direct of travel, and upper base is near the low side sidewall, utilize trapezoidal oblique waist, corresponding coin has then been strengthened the aperture that falls into, other large diameter coins then are beneficial to cross. So just guarantee coin in guide groove, also can only one arranging along the lower cell wall aligning coin dropping hole of advancing with a Horizon, to which kind of position, hole just must leak corresponding coin.

Adopt this device to improve working conditions, increase work efficiency, finish automatically, effectively coin go-no-go, count, pack, fitted tube work; Go-no-go accuracy rate, counting accuracy rate all can reach 100%.

As most preferred embodiment, in the accompanying drawing: (1) shell, (2) guide groove pressing plate, (3) counter, (4) guide groove, (5) light source, (6) coin dropping hole, (7) photosensitive tube, (8) tubulature, (9) belt pulley, (10) thumb wheel, (11) belt pulley, (12) thumb wheel, (13) coin collecting box, (14) guide rail, (15) pressing plate, (16) connecting rod, (17) crank belt pulley, (19) wiring board, (20) body, (21) capacitor, (22) transformer, (23) motor, (24) coin reservoir, (25) table.It is used for one, two, the go-no-go of five-cent piece, 80～100 pieces/minute of go-no-go speed.Coin collecting box, guide groove and guide groove laterally all tilt 5 °; Equidistantly have the coin dropping hole of three (kind) different sizes on the guide groove, one, two, the five-cent piece diameter is respectively 18,21,24mm, coin dropping hole width (promptly go up bottom apart from) is followed successively by 19.5,22.5,25.5mm; Coin thickness is respectively 1.38,1.58,1.74mm, and thumb wheel adopts the rubber tree leaf formula, and blade outer rim and guide groove bottom surface are apart from being 2mm; For avoiding in the vibration thumb wheel out of control, this device adopts two thumb wheels assurance coins to glide along cell wall one by one; The coin reservoir diameter is respectively 20,23,26mm, be connected with tubulature with bayonet socket, but 100 pieces of every saves has corresponding tegillum, omit and use wrapper, and can have enough to meet the need use.
