Abstract
Description
Technical Field
[0001] The utility model relates to the field of billiard ball arranging devices, in particular to a sphere detection device and a billiard ball arranger. Background Art
[0002] At present, during the billiard practice, aiming and serving from different positions and accurately hitting the designated balls on the billiard table into the corresponding pockets are challenges for each billiard player. During this period, it is necessary to repeatedly practice hitting the balls at the same position and the same angle. In traditional billiard training, players need to manually place the balls back to the same position after each hitting action for the next practice. The manual repeated ball placing action takes a long time, and the manual placing method is likely to cause the deviation of the ball placement position from the position where the ball was located during the previous practice. The inaccurate ball placement position makes the players have to practice the hitting action from a new angle and a new hitting point, resulting in poor training effects. Summary of the Utility Model
[0003] Embodiments of the utility model provide a sphere detection device and a billiard ball arranger to solve the problems existing in the related technologies. The technical solutions are as follows:

[0025] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.
[0026] Embodiment 1
[0027] The embodiment of the present utility model provides a sphere detection device, which includes a body, a positioning device 6, a detection device 7 and a controller.
[0028] One end of the body is provided with a ball outlet. There is a cavity in the body, and the cavity is communicated with the ball outlet. A plurality of spheres are accommodated in the cavity, and the spheres can roll out from the ball outlet.
[0029] In this embodiment, in order to accurately control the direction of the sphere rolling out from the ball outlet, a ball track is provided in the cavity of the body. The ball track is communicated with the ball outlet. The sphere is located in the ball track and rolls along the ball track and rolls out from the ball outlet.
[0030] In some embodiments, the ball track can be inclined relative to the horizontal plane, and the inclined ball track helps the sphere to freely roll to the ball outlet.
[0031] A switching device may be provided inside the lane. The switching device may be connected to a controller, and the controller controls the switching device to switch between the open / closed states. When a ball needs to be ejected, the controller controls the switching device to be in the open state, and at this time, the ball inside the lane can freely roll out of the ball outlet. When no ball ejection is required, the controller controls the switching device to close, and at this time, the ball inside the lane will not roll out from the ball outlet. The switching device may be an electromagnetic lock, which has a lock body and a locking blade. When the electromagnetic lock is in the open state, the locking blade retracts into the lock body, and at this time, the ball outlet is not blocked, and the ball can roll out from the ball outlet. When the electromagnetic lock is in the closed state, the locking blade is exposed outside the lock body, thereby blocking the ball and restricting its rolling. The specific structure of the switching device is not limited, as long as it can block the ball.
[0032] As Figure 1 shown, in this embodiment, the machine body includes a main body 1 and a sub-body 3. The lane is provided inside the main body 1. The main body 1 and the sub-body 3 are connected by a horizontally arranged telescopic mechanism 5. The telescopic mechanism 5 includes a telescopic rod and a movable arm, and the movable arm drives the telescopic rod to move horizontally back and forth. The movable arm is driven by a driving motor, and the driving motor is connected to the controller. The controller can control the movement speed and direction of the driving motor, thereby controlling the telescopic state of the telescopic rod. Under the action of the telescopic mechanism 5, the sub-body 3 can be driven to move closer to the main body 1 or to move away from the main body 1.
[0033] In this embodiment, the ball outlet is provided with a first ball outlet 2 and a second ball outlet 4. The first ball outlet 2 is provided on the main body 1, and the second ball outlet 4 is provided on the sub-body 3. The first ball outlet 2 and the second ball outlet 4 are on the same straight line, so that the ball rolling out from the first ball outlet 2 can continue to roll to the second ball outlet 4 under the action of inertia.
[0034] In this embodiment, a positioning device 6 is provided at the second ball outlet 4. The positioning device 6 has an extended state and a retracted state. The positioning device 6 is connected to the controller, and the controller is used to control the switching between the extended / retracted states of the positioning device 6. When the positioning device 6 is in the retracted state, both the length and width of the second ball outlet 4 are greater than the diameter of the ball, so that the ball can pass through the second ball outlet 4 during the movement of the sub-body 3, avoiding the sub-body 3 colliding with the ball and causing the position of the ball to change. When the positioning device 6 is in the extended state, the positioning device 6 is partially exposed at the second ball outlet 4, and partially blocks the second ball outlet 4 so that the length or width of the second ball outlet 4 is less than the diameter of the ball. At this time, when the ball rolls out from the first ball outlet 2 and moves to the second ball outlet 4, it is blocked by the positioning device 6 in the extended state, and the ball stops moving. The position where the ball stays at this time is called the designated point.
[0035] The ball placement operation is as follows: When it is necessary to place the ball at a specified point, control the sub-body 3 to move a specified distance away from the main body 1 starting from the initial position. The size of the specified distance is determined according to the position of the specified point. At the same time, keep the positioning device 6 on the sub-body 3 in the extended state. When the sphere rolls out from the first ball outlet 2 of the main body 1 and then rolls to the second ball outlet 4 under the action of inertia, the positioning device 6 at the second ball outlet 4 blocks the sphere from continuing to roll, and at this time the sphere accurately stops at the specified point.
[0036] To facilitate hitting the ball, the controller controls the positioning device 6 to switch to the retracted state and controls the sub-body 3 to move towards the main body 1 to the initial position. During this period, since the positioning device 6 is in the retracted state, the sphere can smoothly pass through the second ball outlet 4, and the sphere still stays at the specified point. When the sub-body 3 retracts to the initial position, it is equivalent to completing a complete ball placement operation. At this time, enough space can be provided for hitting the ball, and the user can then perform hitting practice on the sphere staying at the specified point.
[0037] During this period, as long as the position of the body and the moving distance of the sub-body 3 remain unchanged, when the ball exits the next time, the sphere can still roll out from the first ball outlet 2 and be blocked by the positioning device 6 at the second ball outlet 4, so as to stay at the same specified point, achieving the effect of accurate ball exit.
[0038] The structure of the positioning device 6 can be the same as that of the switching device. In this embodiment, the positioning device 6 is also set as an electromagnetic lock. The electromagnetic lock includes a lock body and a lock blade. When the electromagnetic lock is in the extended state, the lock blade is exposed outside the lock body. When the electromagnetic lock is in the retracted state, the lock blade retracts into the lock body. The positioning device 6 can also be other structures with a telescopic state, which is not limited here, as long as the positioning device 6 can play the role of blocking the movement of the sphere so that the sphere stays at the specified point.
[0039] To improve the accuracy of sphere judgment, a detection device 7 is provided on the body. The detection device 7 is connected to the controller. The controller can control the on / off state of the detection device 7 and can also control the extended / retracted state of the positioning device 6 according to the collected signals. The detection position of the detection device 7 is directly opposite the ball outlet, and it is used to emit electromagnetic waves to a specified area around the ball outlet and to receive the reflected electromagnetic waves to generate a detection signal. The specified area is a range that extends a certain radius outward with the specified point as the origin to improve the detection accuracy.
[0040] The detection device 7 mainly determines whether there is a sphere in the specified area by emitting electromagnetic waves to the specified area and receiving the reflected electromagnetic waves. The detection device 7 can be one of a laser sensor, an infrared sensor, and a radar sensor.
[0041] In this embodiment, a detection device 7 is provided on the sub-body 3. The detection device 7 is a laser sensor. The detection device 7 has a transmitting end and a receiving end. The transmitting end emits laser light, and the laser light irradiates within a specified area. Assuming that there is a sphere within the specified area, the laser light is reflected by the surface of the sphere and then received by the receiving end. According to the situation of the reflected laser light, it can be determined whether there is a sphere within the specified area. The specific type of the detection device 7 is not limited, as long as it can detect whether there is a sphere within the specified area.
[0042] Due to infrared or laser diffuse reflection, when detecting an object, since the color of the object and / or the intensity of the reflection on the object surface, as well as the reflection result of sunlight or ambient light, are all different. Therefore, in this embodiment, a series of tests can be carried out, testing the voltage received by the receiving end after the laser beam is reflected by different spheres under normal environmental conditions, and the voltage range received by the receiving end when there is no sphere; as Figure 2 shown, the controller is connected to the receiving end of the detection device 7 through its voltage detection port, and the controller can store the voltage obtained from the test. During actual use, when the detection device 7 detects within the specified area, it can determine whether there is a sphere within the specified area according to the voltage received by its receiving end, and even determine the color of the sphere within the specified area. When the ball placement operation is performed, when it is recognized through the detection device 7 that the voltage it receives reaches the voltage range corresponding to the situation when there is no sphere, it means that the sphere staying at the specified point no longer exists, and the next ball placement operation can be immediately executed to place a new sphere at the specified point for the user to practice hitting the ball.
[0043] Embodiment Two
[0044] This embodiment provides a billiard ball placer, which includes a sphere detection device as in Embodiment One. The spheres for detection and placement can be billiard balls. Place the billiard ball placer on the billiard table, place the billiard balls at the specified points on the billiard table, and detect the spheres at the specified points through the detection device 7. It can be determined by the detection device 7 whether the user has hit the billiard balls at the specified points. Assuming that there are no billiard balls at the specified points, new spheres can be placed at the specified points on the billiard table again, improving the ball placement efficiency and accuracy.
