Referring to fig. 1 and 2, embodiments of the present application provide a basketball stacker 10 for detecting the roundness of a basketball. The basketball stacker 10 includes a support 100, a first support plate 210, a second support plate 220, a ball delivery device 300, two roundness measurement plates 400 arranged in parallel, and a basketball stack box 500. The first support plate 210 and the second support plate 220 are perpendicularly and fixedly arranged to each other in a vertical direction. The first support plate 210 and the second support plate 220 have a cross structure. The crisscross structure is arranged on a vertical plane. The first support plate 210 and the second support plate 220 divide the space into four parts. Each portion constitutes a sphere receiving space 201. The central angle of each accommodating space is 90 degrees. The first support plate 210 and the second support plate 220 rotate about the fixed point. The ball delivery device 300 is used for delivering a basketball into one of the ball receiving spaces 201. When the roundness of the basketball needs to be tested, the basketball may be placed in the ball delivery device 300, and the ball delivery device 300 delivers the basketball into one of the ball receiving spaces 201, and then controls the cross structure to rotate.

Referring to fig. 2 to 3, two roundness measurement plates 400 are disposed in parallel and are respectively disposed on two sides of the first support plate 210 and the second support plate 220. Both surfaces of the two roundness measurement plates 400 opposite to each other are provided with a plurality of pressure sensors 410. The plurality of pressure sensors 410 may be uniformly arranged in the roundness measurement plate 400.

A standard pressure sensor 420 is further provided on the surface of each roundness measurement plate 400. The basketball stacking box 500 is disposed on one side of the rotation direction of the first support plate 210 and the second support plate 220. The basketball stacking box 500 is used to stack basketball balls that have undergone roundness testing. For each of the roundness measurement plates 400, the plurality of pressure sensors 410 are disposed around the standard pressure sensor 420.

When the included angle between the first support plate 210 and the second support plate 220 and the horizontal plane is 45 °, the position of the standard pressure sensor 420 coincides with the projection of the center of a basketball with standard roundness on the first support plate 210 and the second support plate 220. The standard roundness basketball is located in the highest height ball receiving space 201.

That is, when the ball receiving space 201 sandwiching a standard basketball is highest, the projection of the center of the standard basketball on the first and

second support plates

210 and 220 falls on the standard pressure sensor 420. The diameter of the standard pressure sensor 420 can be one-thirtieth to one-twentieth of the diameter of the basketball, so that the measurement accuracy can be prevented from being influenced by the overlarge measurement range of the area of the standard pressure sensor 420. Meanwhile, the situation that the standard pressure sensor 420 has too small area so that the test requirement is too harsh can be avoided.

It can be understood that when two roundness measurement plates 400 parallel to each other are close to each other to sandwich a basketball, if the roundness of the basketball is within a predetermined range, the position of the basketball where the two roundness measurement plates 400 first contact must pass through both ends of the horizontal diameter of the center of the basketball, and therefore if the roundness of the basketball is within the predetermined range, it is inevitable that the projection of the center of the basketball on the roundness measurement plate 400 first contacts the roundness measurement plate 400.

The two roundness measuring plates 400 are used to respectively approach and press both sides of the basketball located in the ball receiving space 201 at the uppermost position when the angles between the first supporting plate 210 and the second supporting plate 220 and the horizontal plane are 45 °.

If the standard pressure sensor 420 of each roundness measurement board 400 first receives a pressure signal, that is, the orthographic projection of the center of the basketball on the roundness measurement board 400 falls on the standard pressure sensor 420. The basketball deformation degree can be within the acceptable range at the moment. Judging that the roundness of the basketball is qualified;

at this time, the first support plate 210 and the second support plate 220 may be driven to rotate counterclockwise, so that the basketball falls into the basketball stacking box 500. At this time, a new basketball to be tested can be placed in the ball delivery device 300, and the basketball is delivered to the nearest ball receiving space 201 to continue the circular detection. Therefore, the efficiency of the whole detection process is greatly improved.

In one embodiment, if the pressure sensor 410 of each roundness measurement plate 400 receives a pressure signal first than the standard pressure sensor 420, which indicates that the maximum diameter of the basketball does not pass through the center of the circle due to deformation, the roundness of the basketball is determined to be not qualified. The basketball with the out-of-roundness can be taken out manually or by other existing mechanical structures.

It can be understood that the above process can be performed manually, or the device can be controlled by using a control module such as a PLC.

In one embodiment, a slide rail 510 is disposed at the opening of the basketball stacking box 500. The slide rail 510 is vertically disposed. The sliding rail 510 is slidably provided with a ball pressing plate 520. The bottom of the sliding rail 510 is provided with a rotating plate 530. The rotating plate 530 rotates to a horizontal position when the ball pressing plate 520 is pressed down. The rotation of the pivotal plate 530 in the vertical direction allows the basketball to fall into the basketball goal stack 500. The rotating plate 530 may be controlled by a motor. The rotating plate 530 may serve as a cover for the basketball goal stacking box 500. When the rotating plate 530 is horizontally disposed, the ball pressing plate 520 and the rotating plate 530 are arranged in parallel. When the basketball test is passed, the skateboard 540 may be slid onto the pivotal board 530. The rotating plate 530 is in a horizontal position at this time. The basketball is then deflated, while the footplate 520 is depressed to facilitate deflation of the ball. The rotation of the rotating plate 530 may be controlled to allow the basketball to fall into the basketball goal stack 500 after the basketball has deflated.

In one embodiment, the ball pressing plate 520 is provided with a blow-off pin 522 at a side thereof adjacent to the basketball stacking box 500.

When the roundness of the basketball is judged to be qualified, the position of the basketball is controlled, the air release needle 522 is inserted into the air hole of the basketball by pressing the basketball pressing plate 520 downwards, meanwhile, the air release of the basketball is realized by continuously pressing the basketball pressing plate 520 downwards, and after the air release of the basketball is finished, the rotating plate 530 is controlled to rotate so that the basketball falls into the basketball stacking box 500. That is, after the basketball passing the test falls on the rotating plate 530, the eye of the basketball may be controlled to be aligned with the deflation needle 522. The process can be controlled manually or automatically by image processing techniques. The ball pressing plate 520 is then controlled to press down, so that the basketball rim deflates.

In one embodiment, the ball delivery apparatus 300 includes a basketball stand 310 and a horizontal pusher 320. The horizontal pushing plate 320 is disposed on the surface of the basketball stand 310, and the horizontal pushing plate 320 can move left and right. When the basketball is placed on the basketball stand 310, the horizontal push plate 320 pushes the basketball to the ball receiving space 201 closest thereto. And the basketball can be maintained at the position closest to the ball receiving space 201 to prevent the basketball from falling off from the ball receiving space 201, and the height of the horizontal push plate 320 is higher than the height of the first support plate 210 and the second support plate 220 at any position. Therefore, the horizontal push plate 320 can always restrain the basketball in the ball receiving space 201 before the basketball reaches the highest point of the cross structure, and the basketball is prevented from falling out of the ball receiving space 201.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
