Embodiment
As shown in Figure 1; Coin checkout equipment provided by the present invention comprises the transmission portion that is used for transmitting coin, the shoot part that is used for the coin of transport process is carried out to picture; And the light source portion that is used for providing the light of suitable angle and intensity, and be used for the electrical measurement parameter detecting portion that the coin electromagnetic parameter detects to shoot part.Coin checkout equipment provided by the present invention also comprises the control system that is used to control transmission portion, shoot part and light source portion.
Transmission portion comprises the driving belt group that is made up of three belts and goes out the coin plate.According to the direction of transfer of coin, the driving belt group comprises the front feed belt 9 that is positioned at into the coin mouth successively, is arranged in the Two surface leather belt 8 of the arc of belt 9 one sides (left side of Fig. 1), and the reverse side feed belt 10 that is arranged in the opposite side (right side of Fig. 1) of belt 9.Go out the downstream on the coin direction of transfer that the coin plate is connected reverse side feed belt 10.
Front feed belt 9 has horizontal part, curved portions and oblique portion, and the starting point of horizontal part is positioned at the below into the coin mouth, and arc part is in the downstream on the coin direction of transfer of horizontal part.Horizontal part has formed positive horizontal channel 22, accepts from the coin of going into the coin mouth, and has enough length to adapt to shoot part and light source portion requirements of one's work.When coin falls on the front feed belt 9 (going into the coin mouth also can be that other makes coin pursue a piece defeated coin device that gets into front feed belt 9); Because frictional resistance can rapid certain one side (front) mode up with coin lie low, and does not have the slip of rotation or phase frontal feed belt 9.
The curved portions of front feed belt 9 with the mode tangent with horizontal part, is connected to the downstream on the coin direction of transfer of horizontal part.The Two surface leather belt 8 of arc just in time matches with the curved portions of front feed belt 9, forms the curved channel 23 with the horizontal part smooth connection.Thus, coin is carried to curved portions from horizontal part, gets into curved channel 23.Because front feed belt 9 is opposite with the traffic direction of Two surface leather belt 8, one is that clockwise another is exactly counterclockwise, so just can make coin in curved channel 23, is being held under the arm and the rapid curved channel 23 that passes through by front feed belt 9 and Two surface leather belt 8 folders.Owing to be that curved channel 23 is arc (being semicircular in Fig. 1), coin still faces up when getting into, and just is flipped to when going to the terminal point of curved channel 23 to have faced down.At this moment, coin is flipped to and is reverse side (side opposite with aforementioned front) state up.
Form rising passway 24 between the oblique portion of front feed belt 9 and the reverse side feed belt 10.Rising passway 24 is connected the terminal point of curved channel 23, and extends to the starting point next door of the horizontal channel 22 of horizontal part.Front feed belt 9 is opposite with the traffic direction of reverse side feed belt 10, and therefore, the coin after being reversed is just keeping reverse side state up after getting into rising passway 24 from curved channel 23, is transported on the positive horizontal channel 22.
Reverse side feed belt 10 has rake and the horizontal rear portion that is complementary with front feed belt 9.Aforementioned rising passway 24 is established and is formed by the oblique portion of front feed belt 9 and the rake folder of reverse side feed belt 10.Horizontal rear portion then is formed on the opposite side (in Fig. 1, the traffic direction of coin is left, and then the starting point at horizontal rear portion is located in the right side into the coin mouth) of coin mouth, and maintenance and front feed belt 9 horizontal alignments, forms reverse side horizontal channel 25.Coin gets into reverse side horizontal channel 25 from rising passway 24 thus.
Go out the destination county that the coin plate is connected reverse side horizontal channel 25, and have a certain degree, so that after coin is slipped to out the coin plate on the horizontal rear portion of feed belt 10 from the negative, lean on self gravitation and along going out the downward landing of coin plate with reverse side horizontal channel 25 shapes.
In the present embodiment, belt 8 turns clockwise, and belt 9 is rotated counterclockwise, and belt 10 turns clockwise.Because Two surface leather belt 8 is identical with turning to of reverse side feed belt 10, can be a belt therefore, just there is not joint between such two belts, coin to be detected is not easy to be stuck.
Introduce the concrete structure of shoot part and light source portion below.
Shoot part comprises front shoot part, reverse side shoot part and goodness of fit shoot part, and corresponding, light source portion also comprises positive light source portion, reverse side light source portion and goodness of fit light source.
