Abstract

The utility model belongs to a mechanical type coin collector which receives metal coins. The utility model is provided with a double-pawl mechanism for controlling the thickness of a coin and a non-return pawl mechanism for controlling the reversal of a movable wheel. The coin collector can accurately detect the dimensions of the diameter and the thickness of the coin, causing a true coin to enter a coin storage box through the coin collector smoothly. If a coin is fake, the double-pawl mechanism blocks the coin to pass, and a handle is rotated to quit an unqualified coin. The non-return pawl mechanism can prevent the reversal of the movable wheel. When the coin falls down, the non-return pawl is caused to cross the movable wheel to guarantee movable wheel one-way intermittent rotation. The coin collector is suitable for a vending machine, a time service machine and a game machine using the metal coins.

Description

Coin-freed arrangement

Technical field

The utility model belongs to a kind of mechanical hook-up, promptly receives the coin-freed arrangement in petty commodities automatic vending machine (Vending Machine), game machine and other the metered machine of metal coin.

Background technology

Mainly there is following defective in coin-freed arrangement in particularly external at present petty commodities automatic vending machine (Vending Machine), game machine and other the metered machine that generally uses: 1.Excessive for the non-standard metal coin size Control error that non-coin-freed arrangement receives, true and false coin recognition efficiency is low: 2.Monodactyle is bigger to coin surface convex-concave pattern and chimb resistance, operation inconvenience.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming in the existing structure design, thereby a kind of more accurate control coin thickness is provided, and reduces counterfeit money and throws in the loss that brings, the coin-freed arrangement of the coin dimensions control of more convenient user's operation.

The technical scheme that its technical matters that solves the utility model adopts is: two pawl mechanism is hinged on the pressing plate, and two pawl spacings are suitable with tested coin diameter, and front and back pawl line is cut in heart track garden, coin garden, and two pawls back side recoil press spring makes it be attached to the driving wheel surface all the time.According to the fixed lever error amplification principle that changes two pawls, when by the straight warp counterfeit money different with genuine note with thickness, two pawls just are stuck on the driving wheel, and the prevention counterfeit money falls.

Use link stopper and detent mechanism make genuine note enter coin reservoir smoothly and realize the purpose of repeatable operation.For preventing that detent (Fig. 3) is stuck in the opening part that driving wheel contacts with coin after coin falls, after coin falls, detent block (Fig. 4) is run into the detent rear portion, and its pawl front portion is lifted, and the rotating operation handle is rotated further driving wheel and gets back to initial coin slot position.Link stopper and detent mechanism are made up of detent, retracing spring and block, and the detent front portion is along the driving wheel a plurality of gradually deep trouth directions of annular and be stuck in groove depth portion, and block and driving wheel coaxial rotation are installed on initial coin slot direction.

The beneficial effects of the utility model are: can more accurately differentiate the true and false circular metal coin of control, reduce coin contact pressing plate and its control pawl time, improve identification efficiency.

Description of drawings

The utility model is described in further detail below in conjunction with Figure of description embodiment.

Accompanying drawing is a part-structure synoptic diagram of the present utility model.

Fig. 3 is detent side figure.

Fig. 4 is the detent block.

Among the figure 1.Two pawls: 2.Two pawl recoil press springs: 3.Detent: 4.Detent back-moving spring: 5.The block that forces coin directly to fall: 6.The compressing tablet that connects the panel pressing plate: 7.Panel: 8.Detent block: 9.Driving wheel: 10.Pressing plate: 11.Two pawl stage clip bayonet sockets.

Embodiment

In Fig. 1 embodiment, driving wheel (9) is positioned between pressing plate (10) and the panel (7), and a concave station that adapts with coin and a plurality of annulars on same circle deep trouth is gradually counterclockwise arranged on the driving wheel.Coin put into behind the concave station its surface should with the driving wheel isoplanar.After coin was put into concave station from opening part, driving wheel rotated with handle (not drawing in the back side) counterclockwise together with coin.When coin was standard size, two pawls slipped over along driving wheel and coin surface and do not rotate.Genuine note is rotated further handle drive driving wheel and rotates back into opening part after the detection of two pawl (1) mechanisms falls, and finishes a circulation.Two pawl recoil press springs (2) remain with two pawl front compression spring bayonet sockets (11) and contact.

Fig. 2 is two pawl side figure, and wherein two pawls (1) divide fore paw and rear solid end, and belonging to changes member surely, is hinged on the pressing plate with pivot pin.The front and back pawl should be positioned on driving wheel and the coin plane when working.When metal coin thickness overgauge, fore paw blocks it, and when coin thickness during less than standard, fore paw is stuck in the antemarginal driving wheel clockwise direction of coin gradually in the deep trouth.

Among Fig. 3, detent (3) is aimed at gradually deep trouth of driving wheel annular all the time, makes it do unidirectional intermittence and rotates.Back-moving spring (4) guarantees that detent is pressed in the driving wheel annular gradually on the deep trouth, and makes the back-moving spring compression when the detent block is pressed in the detent rear portion.Pivot pin makes detent and pressing plate hinged.

Fig. 4 is detent block (8), connects firmly rotation with driving wheel key axle, when it goes to the detent rear portion it is depressed, and makes the last time pawl stride across the concave station opening of putting coin on the driving wheel.

Claims

1. mechanical type coin-freed arrangement that receives metal coin, its feature comprise two pawl mechanisms of detecting the control coin thickness, detent mechanism and the pressing plate lower left corner opening that coin is directly fallen of an anti-driving wheel counter-rotating.

2. coin-freed arrangement as claimed in claim 1, it is characterized in that: the fore paw of two pawl mechanisms and rear solid end spacing are suitable with coin diameter, and its centre of gyration is hinged on the pressing plate, and the preceding back side of pawl is the position stage clip once.

3. coin-freed arrangement as claimed in claim 1, it is characterized in that: detent mechanism is made up of detent, retracing spring and block, the detent front portion is along the driving wheel a plurality of gradually deep trouth directions of annular and be stuck in groove depth portion, and block and driving wheel coaxial rotation are installed on initial coin slot direction.

4. coin-freed arrangement as claimed in claim 1, it is characterized in that: there is an opening that coin is fallen in the pressing plate lower left corner.
