AI Technical Summary
The existing billiards automatic swing ball ball device cannot accurately stay at a fixed point due to squeezing and impact during the rolling process of the ball, which affects the swing accuracy.
A spherical pointing device is designed, including a fairway and a retractable pointing device. The fairway tilt design allows the sphere to roll in the inclined direction. The fixed-pointing equipment restricts the sphere when it is extended to ensure that it stays at a specific point and allows the sphere to pass in the contracted state, thereby achieving accurate rolling and placement of the sphere.
The spheres in the fairway are separated by retractable fixed-pointing equipment, so that the spheres can be rolled out freely along the fixed fairway route, ensuring that each sphere can roll to the same fixed point, improving the accuracy and efficiency of ball swing operation.

Description
Technical Field
[0001] The utility model relates to the technical field of billiards, in particular to a sphere positioning device and an automatic billiard ball racking device. Background Art
[0002] In order to improve the efficiency of racking billiard balls, an automatic billiard ball racking device has been introduced at present, which can automatically collect and arrange billiard balls into a triangular shape on a billiard table. During this process, each sphere needs to roll through a ball track to a fixed position on the racking device, and then the racking device can automatically perform a series of subsequent racking operations. However, since the balls in the ball track are all squeezed together, the balls at the back in the ball track squeeze the balls at the front, or the balls at the back hit the balls at the front during the rolling process, which will cause the line of the balls at the front to change when they roll out of the ball track, resulting in the spheres being unable to accurately stop at the fixed positions. Summary of the Utility Model
[0003] Embodiments of the utility model provide a sphere positioning device and an automatic billiard ball racking device to solve the problems existing in the related art. The technical solutions are as follows:

[0006] A positioning device, located at a position in the ball track close to the outlet, and the distance from the positioning device to the outlet is greater than the diameter of the sphere.
[0007] The positioning device has at least two states, including an extended state and a contracted state; in the cross-section of the ball track, when the positioning device is in the extended state, the vertical distance between the lowest point of the positioning device and the bottom wall of the ball track is less than the diameter of the sphere, so that the sphere is limited at the positioning device; when the positioning device is in the contracted state, the vertical distance between the lowest point of the positioning device and the bottom wall of the ball track is greater than the diameter of the sphere, so that the sphere passes through the positioning device and freely rolls out from the outlet.
[0008] In an embodiment, the ball track is composed of at least two guide rods combined, and the distance between the two guide rods is less than the diameter of the sphere, so that the sphere rolls along the guide rods.

[0012] In one embodiment, the preset distance is greater than the diameter of the ball and less than twice the diameter of the ball.

[0018] In a second aspect, an embodiment of the present invention provides a billiard automatic ball placer, including the ball fixed-point device as described above.
[0019] The advantages or beneficial effects in the above technical solutions at least include:

[0027] 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.
[0028] Embodiment 1
[0029] This embodiment provides a sphere fixed-point device, which includes a lane 1 and a fixed-point device.
[0030] As Figure 1 shown, the lane 1 is provided with a hollow structure, the sphere is located in the hollow lane 1, and the lane 1 is inclined relative to the horizontal plane. Its inclination angle can be set according to the actual situation, and it can be between 1 degree and 5 degrees. In this embodiment, the inclination angle of the lane 1 is 1 degree. Due to the inclination, the sphere in the lane 1 can freely roll along the inclined direction. The end with a relatively higher height on the lane 1 can be docked with the sphere collection track on the billiard table. After the billiard ball drops into the pocket, it rolls through the sphere collection track to the lane 1 of this embodiment, and there is a ball outlet 2 at the end with a relatively lower height on the lane 1. The sphere located in the lane 1 freely rolls along the inclined direction to the ball outlet 2.
[0031] It should be noted that the position close to the ball outlet 2 is the front of the lane 1, and the position far from the ball outlet 2 is the rear of the lane 1. In this embodiment, the whole lane 1 inclines downward in the front direction, so that the height of the front position of the lane 1 is relatively lower, and the height of the rear position of the lane 1 is relatively higher.
[0032] A fixed-point device is provided inside the lane 1. The number of fixed-point devices can be set according to actual needs, and the fixed-point devices can be set at any position inside the lane 1 according to actual needs. In this embodiment, there is a fixed-point device located inside the lane 1 near the ball outlet 2, and the distance from this fixed-point device to the ball outlet 2 is greater than the diameter of the ball, so that there is a space in front of the fixed-point device for accommodating one ball, and the ball behind is blocked by the fixed-point device at this position and cannot roll freely.
[0033] In some embodiments, a switch gate can also be provided at the ball outlet 2 of the lane 1. The switch gate is closed when the ball is not required to drop. At this time, the ball is located in the space at the ball outlet 2 inside the lane 1. At this time, the ball at the ball outlet 2 can also be separated from the ball behind it by the fixed-point device. After the ball at the ball outlet 2 rolls out through the opened switch gate, the switch gate is closed. When the fixed-point device is controlled to switch to the contracted state, the ball behind passes through the fixed-point device and stays at the ball outlet 2, and the switch valve is opened again when the ball is required to drop.
[0034] In some embodiments, if it is necessary to ensure that the ball rolls to a fixed point at a certain speed, the position of the fixed-point device inside the lane 1 can be controlled and adjusted. Assuming that after a fixed-point device separates one ball from the ball behind, the ball can continue to roll freely along the lane 1 until it rolls out through the ball outlet 2 at a certain speed. At this time, the rolled-out ball has a certain acceleration and can fall to a specified fixed point at a certain distance from the ball outlet 2.
[0035] The rolling route of the ball inside the lane 1 is fixed. In this embodiment, the lane 1 is assembled into a cuboid shape by transparent plates. At this time, the flat transparent plate serves as the bottom wall of the ball, and the width of the bottom wall of the lane 1 is greater than the diameter of the ball, so that the ball can roll on the bottom wall.
[0036] In some embodiments, in order to further fix the rolling route of the ball inside the lane 1, a groove is provided on the bottom wall of the lane 1. The groove extends along the length direction of the lane 1 to the ball outlet 2. The bottom end of the ball sinks into the groove and rolls freely along the groove; and the width and depth of the groove are related to the diameter of the ball. Assuming the diameter of the ball is 57mm, the width of the groove can be 8.6MM and the depth is 1.5MM.
[0037] In some embodiments, the lane 1 itself can be composed of at least two guide rods combined. The distance between the two guide rods is less than the diameter of the ball, so that the ball can roll along the guide rods. At this time, the ball completely rolls along the direction of the guide rods, and the groove does not need to be set to fix the rolling route of the ball.
[0038] In some embodiments, the ball track 1 can also be the existing ball collection track on a billiard table. The existing ball collection track on the billiard table is modified, and the positioning device is installed on the ball collection track on the billiard table, so that the collected balls can accurately roll into the automatic billiard ball setter.
[0039] In this embodiment, the positioning device has at least two states, including an extended state and a contracted state; the state switching of the positioning device can be controlled manually or electrically. In the cross-section of the ball track 1, when the positioning device is in the extended state, the vertical distance between the lowest point of the positioning device and the horizontal plane where the lowest point of the ball track 1 is located in this perspective is less than the diameter of the ball, so that the ball can be restricted by the positioning device to roll and stay at the positioning device; in the cross-section of the ball track 1, when the positioning device is in the contracted state, the vertical distance between the lowest point of the positioning device and the horizontal plane where the lowest point of the ball track 1 is located is greater than the diameter of the ball, so that the ball can smoothly pass through the positioning device and freely roll out from the ball outlet 2.
[0040] In this embodiment, the number of positioning devices is set to two, as Figure 1 shown. The positioning device close to the ball outlet 2 is the first positioning device 3, and the positioning device far from the ball outlet 2 is the second positioning device 4. There is a preset distance between the first positioning device 3 and the second positioning device 4. The preset distance is greater than the diameter of the ball and less than twice the diameter of the ball. The distance from the second positioning device 4 to the ball outlet 2 is greater than the diameter of the ball; while the first positioning device 3 is installed at the ball outlet 2. In this embodiment, the first positioning device 3 and the second positioning device 4 are installed side by side directly above the ball track 1. Since the diameter of a ball is 57 mm and 5 mm is added as the interval, the distance between the first positioning device 3 and the second positioning device 4 can be 62 mm.
[0041] The second positioning device 4 blocks the balls behind. After the first positioning device 3 is opened, the balls located between the first positioning device 3 and the second positioning device 4 can freely roll out of the ball track 1. After the balls in front have rolled out of the ball track 1, the first positioning device 3 is closed and the second positioning device 4 is opened, allowing one ball behind to roll into the space between the first positioning device 3 and the second positioning device 4. Immediately afterwards, the second positioning device 4 is closed to block the balls behind from rolling and hitting the balls in front. At this time, it is possible to wait for the opportunity to release the balls at the ball outlet 2.
[0042] In this embodiment, as Figure 2 shown, the positioning device is an electromagnetic lock 5. The electromagnetic lock 5 has a retractable locking blade 6. The locking blade 6 is extended or retracted into the electromagnetic lock 5 by an electric control method. The internal structure of the electromagnetic lock 5 has been disclosed in the prior art and will not be described in detail here.
[0043] The fixed-point device can also be a device with a telescopic function such as a telescopic rod. The specific type of the fixed-point device is not limited here, as long as the fixed-point device can switch between the extended state and the retracted state. When the locking knife 6 is in the extended state, the locking knife 6 extends, and the vertical distance from the lowest point of the locking knife 6 ( Figure 2 point A shown) to the bottom wall of the ball track 1 ( Figure 2 plane O shown) is less than the diameter of the sphere, so as to prevent the sphere from continuing to roll forward obliquely; when the locking knife 6 is in the retracted state, the locking knife 6 retracts into the electromagnetic lock 5, and the vertical distance from the lowest point of the electromagnetic lock 5 (such as Figure 3 point B shown) to the bottom wall of the ball track 1 (such as Figure 3 plane O shown) is greater than the diameter of the sphere. At this time, the sphere can smoothly pass through the electromagnetic lock 5 to reach the front position of the ball track 1 or freely roll out from the ball outlet 2 of the ball track 1.
[0044] To improve the degree of automation, the sphere fixed-point device further includes a controller, which is connected to all vertex devices and is used to control the switching timing of the fixed-point device between the extended state and the retracted state, so as to achieve the effect that the sphere rolls to a fixed position, preventing the balls behind from squeezing and hitting the balls in front, resulting in a change in the rolling route of the balls in front during free fall, so that the balls in front can accurately land at the fixed position during free fall rolling.
[0045] In one embodiment, the sphere fixed-point device further includes a position sensor, which is located in the ball track 1 and is connected to the controller. The position sensor is used to detect the position of the sphere and generate an in-place signal when the sphere is at a preset position. The in-place signal is used to control the switching of the fixed-point device between the extended state and the retracted state. The position sensor can be a laser diffuse reflection device, and a laser diffuse reflection device is provided behind the fixed-point device to detect whether there is a ball at the corresponding position in the ball track 1. The detection information of the position sensor is uploaded to the controller, and the controller comprehensively controls the expansion and contraction states of each fixed-point device.
[0046] Embodiment 2
[0047] This embodiment provides an automatic billiard ball setter, which includes the sphere fixed-point device described in Embodiment 1 and an existing ball setter. The sphere fixed-point device can accurately roll the sphere to the fixed position on the ball setter, and the ball setter can smoothly perform the ball setting operation. The structure of the ball setter itself has been disclosed in the prior art and will not be described in detail here.
