Description

Technical Field

[0001] The present application relates to the technical field of coin-operated machines, and in particular to a coin detection device and a coin-operated machine. Background Art

[0002] The existing coin-operated machine uses a detection structure of multiple optical sensors arranged linearly to detect coins. For example, CN102110330A discloses a token (coin) identification device, in which a token channel is provided, and multiple optical sensors arranged linearly are provided in the token channel. When the token enters the token channel and rolls in the token channel, the corresponding optical sensors among the multiple optical sensors respectively identify the first start hole, the second start hole, the first sensing hole and the second sensing hole of the token, so as to judge the authenticity of the token according to the identification result. Although the device has a strong targeted and exclusive identification ability when identifying the token with the first start hole, the second start hole, the first sensing hole and the second sensing hole, the defect of the device is that due to the small receiving range of the linearly arranged optical sensors, it is easy for the optical sensor to fail to align with the first start hole, the second start hole, the first sensing hole or the second sensing hole of the token, resulting in the device failing to identify any of the first start hole, the second start hole, the first sensing hole or the second sensing hole of the token, thereby affecting the result of the device determining the authenticity of the token, and it is easy to judge the real token as a fake token.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0034] See also Figure 1-Figure 7 , a coin detection device, comprising a detection channel 11, arranged inside a coin machine 1 body; a detection component 210, arranged on the detection channel 11 and used to detect a coin 3 with a hole, comprising a signal transmitter 211 and a signal receiver 212 arranged opposite to each other;

[0035] The signal transmitter 211 is composed of a plurality of light sources 2110 projecting toward the signal receiver 212 . The light sources 2110 are arranged in a matrix to project a matrix light beam in the direction of the signal receiver 212 .

[0036] It is understandable that the number of matrix light sources 2110 in this embodiment is multiple, for example, the matrix can be composed of 8*8 LED lights or infrared lasers. Since multiple light sources 2110 form a matrix, the light signal emitted by the signal transmitter 211 through these light sources 2110 covers an area, and the size of the area is determined by the size of the matrix composed of the light sources 2110.

[0037] See also Figure 1 In this embodiment, the signal transmitter 211 is a laser transmitter, and the signal receiver 212 is a light sensor. The laser transmitter and the light sensor, which are composed of a matrix of multiple light sources 2110, are respectively located on both sides of the detection channel 11, and the coin 3 passes between the laser transmitter and the light sensor when moving in the detection channel 11. When the coin 3 passes through the laser transmitter and the light sensor, the laser transmitter irradiates a wide range of light signals onto the coin 3, and part of the light signals are blocked by the coin 3 and cannot be transmitted to the light sensor, while the light signals that are not blocked by the coin 3 and can reach the light sensor constitute a light and shadow image, and the pattern characteristics of the coin 3 can be determined based on the light and shadow image.

[0038] The coin detection device further includes a controller 2 disposed in the body of the slot machine 1 , and the controller 2 is electrically connected to the detection component 210 .

[0039] The controller 2 includes a data storage module (data storage or chip) 22 and a detection module 21 arranged on a control circuit board. The detection module 21 includes at least one detection component 210. The detection component 210 is electrically connected to the control circuit board through a wire.

[0040] The detection component 210 is arranged on the inner wall of the detection channel 11, and is used to detect the coin 3 when the coin 3 enters the detection channel 11 through the coin slot 101, so as to obtain the pattern characteristics of the coin 3, and compare the obtained pattern characteristics of the coin 3 with the preset pattern characteristic data (graphic characteristics, picture characteristics or image characteristics represented by electrical signals) stored in the data storage module 22, so as to determine whether the coin 3 is the target coin; it should be noted that, in the preferred scheme, the coin 3 is constructed with a hole, and the coin 3 with a hole is widely used because of its convenient production and processing, so the detection component 210 is often used to detect the coin 3 with a hole.

[0041] Furthermore, the coin detection device has a first coin output port 102 connected to the coin falling channel in the body of the coin machine 1, and a second coin output port 103 connected to the output channel in the body of the coin machine 1, and a screening device 111 has a first position state and a second position state; when the screening device 111 is in the first position state, the detection channel 11, the coin falling channel, and the first coin output port 102 are connected; when the screening device 111 is in the second position state, the detection channel 11 is not connected to the coin falling channel; it should be noted that the function of the output channel is to output the coin 3 determined as a non-target coin after detection from the coin machine to complete the coin return, and the function of the coin falling channel is to drop the coin 3 determined as a target coin after detection into the coin machine 1 for retention.

[0042] The coin detection device further comprises a screening device 111 disposed in the body of the slot machine 1 , and the screening device 111 is electrically connected to the controller 2 ; the screening device 111 is movably disposed in the body of the slot machine 1 .

[0043] The control circuit board of the controller 2 is electrically connected to the driver of the screening device 111. When the detection component 210 completes the detection of the coin 3, if the coin 3 is a non-target coin, the screening device 111 is in an inactive state (second position state), and the non-target coin is output from the second coin outlet 103 through the output channel, and the coin machine 1 completes the coin return; if the coin 3 is a target coin, the screening device 111 is in an active state (first position state), and the target coin is output from the first coin outlet 102 through the coin drop channel and falls into the coin machine 1 for retention.

[0044] The screening device 111 includes a baffle and a driver movably arranged in the body of the slot machine 1. The output shaft of the driver is in transmission connection with the baffle, and the driver drives the baffle to move so that the screening device 111 switches between the first and second positions. The driver is a motor with an electric push rod or a cylinder with a telescopic piston rod.

[0045] Optionally, in some embodiments, the screening device 111 can be a switch. When the screening device 111 is in an open state according to the instruction of the controller 2, the target coins are output through the first coin output port 102; when the screening device 111 is in a closed state according to the instruction of the controller 2, the non-target coins are output through the second coin output port 103.

[0046] Optionally, in some embodiments, the detection component 210 further includes a camera for capturing images, for capturing pattern features of the coin 3 projected onto the inner wall of the detection channel, instead of the signal receiver 212 .

[0047] The coin detection device has a fixed area 112 for positioning the coin 3 on its detection channel 11, the detection component 210 is located in the fixed area 112, and a fixing mechanism 1120 with a first state and a second state is provided in the fixed area 112;

[0048] When the fixing mechanism 1120 is in the first state, the fixing mechanism 1120 acts on the coin 3 and positions the coin 3 on the fixing area 112 . When the fixing mechanism 1120 is in the second state, the fixing mechanism 1120 does not act on the coin 3 .

[0049] Optionally, in some embodiments, the fixing mechanism 1120 includes a telescopic baffle, and the detection channel 11 is provided with an opening corresponding to the baffle, so that when the baffle is in the first state, it is exposed from the opening to block the coin 3 from escaping from the detection channel 11.

[0050] Optionally, in some embodiments, the fixing mechanism 1120 includes an electromagnetic adsorption component, which has magnetism to adsorb the coin 3 entering the detection channel 11 when in the first state.

[0051] A plurality of fixed areas may be provided in the detection channel 11. For example, in a specific embodiment, after the coin 3 enters the detection channel 11 through the coin slot 101, it will move obliquely downward along the detection channel 11. During the movement of the coin 3 in the detection channel 11, when the coin 3 reaches the first fixed area 112, if the fixing mechanism 1120 of the first fixed area 112 is in the first state, the coin 3 will be positioned in the first fixed area 112; if the fixing mechanism 1120 of the first fixed area 112 is in the second state, the coin 3 will pass through the first fixed area 112 to reach the second fixed area 112. By analogy, during the process of the coin 3 sequentially moving from the first fixed area 112 to the last fixed area 112, the moving speed of the coin 3 decreases. Therefore, during the movement of the coin 3 in the detection channel 11, when the coin 3 passes through the detection component 210, there is time to detect the coin 3, which facilitates the detection component 210 to detect the coin 3 to obtain the pattern characteristics of the coin 3.

[0052] The coin detection device has a coin slot 101 connected to a detection channel 11 on the coin machine 1. Optionally, in some embodiments, the coin slot 101 allows only one coin 3 to pass through at a time, and the inner diameter of the detection channel 11 is larger than the outer diameter of the coin 3, which can be understood as a clearance fit between the coin 3 and the detection channel 11.

[0053] See also Figure 4 and Figure 5On the basis of the above embodiments, an improved coin detection device is provided in the present embodiment, in which a coin slot 101 and a second coin outlet 103 are located on the same side of a coin machine 1; a detection channel 11 is inclined and forms a preset inclination angle with the horizontal line, an end of the detection channel 11 in the vertical direction above is the coin slot 101, and an end of the detection channel 11 in the vertical direction below is provided with a screening device 111; the second coin outlet 103 is connected to the screening device 111 through an output channel.

[0054] Optionally, the coin 3 falls into a non-target coin storage bin along the direction of the second coin outlet 103, and the non-target coin storage bin is arranged below one side of the outlet of the detection channel 11 (it can be understood that the non-target coin storage bin and the outlet of the detection channel 11 are not on the same axis), so as to prevent non-target coins from accumulating in the output channel and prevent non-target coins accumulated in the output channel from accidentally falling into the first coin outlet 102 when the screening device is turned on;

[0055] Optionally, the first coin outlet 102 is located directly below the exit of the detection channel 11 , and the target coin falls into the first coin outlet 102 through the coin drop channel in a vertical state under the action of gravity.

[0056] Optionally, the detection channel 11 is arranged at an angle in the body of the coin machine 1, and the height of one end of the detection channel 11 close to the coin slot 101 is greater than the height of the other end of the detection channel 11 away from the coin slot 101. When the screening device 111 is in the first position, the target coin slides along the detection channel 11 to the first coin outlet 102.

[0057] See also Figure 6 Based on the above embodiment, this embodiment provides an improved slot machine 1, which includes the coin detection device in the above embodiment.

[0058] See also Figure 7 An embodiment of the present application provides a coin 3, which is used in a coin detection device of any of the above embodiments. The coin 3 includes one or more perforations 301, and the perforations 301 are distributed on the surface of the coin 3 according to preset rules and form a preset pattern.

[0059] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
