[0027] In the ball packaging industry, it is necessary to pack the balls into the packaging frame according to the predetermined number. The existing technology mainly adopts the conveying belt to send the balls to the frame opening above, and controls the frame through time control or weight control. However, this method has the following technical problems: first, when the balls continuously fall into the frame, due to the action of gravity, the rebound of the balls already packed is caused, and the arch bridge phenomenon is formed, which seriously affects the stability and filling density of the frame; second, the frame position is unstable, and it is difficult to ensure that each frame position is accurately aligned with the discharge port; third, the timing of indexing stop is difficult to match with the ball counting, which causes the inaccurate number of frames and affects the consistency of packaging quality.

[0028] As shown in Figures 1-4 , according to the embodiment of the present embodiment, the ball automatic frame equipment includes a rack 1, an indexing rotary table 2, a driving dial 4, a ball mouth slot wheel 5, a second dial 8 and a short section guide groove 9.

[0029] The rack 1 is the support base of the whole device, and a circular indexing turntable 2 is fixedly installed on the upper end face of the rack 1. The indexing turntable 2 is installed on the rack 1 through a bearing and can rotate around a vertical axis. The outer periphery of the indexing turntable 2 is uniformly provided with four radial grooves, which cooperate with the driving pins of the driving dial 4 to form an outer-groove Geneva mechanism. Four frame position holes are correspondingly provided on the table surface of the indexing turntable 2, the frame position holes penetrate through the indexing turntable 2, and the hole bottoms are connected to lifting plates for carrying the packaging frames 11 to be filled.

[0030] In some embodiments, the outer-groove Geneva mechanism is a four-groove outer-groove Geneva mechanism, the driving dial 4 is fixed on a main shaft, the main shaft is driven to rotate at a constant speed by the first motor 3, a driving pin is fixedly installed on the outer periphery of the driving dial 4, and the driving pin periodically enters the radial grooves of the indexing turntable 2 during rotation to drive the indexing turntable 2 to intermittently rotate by 90 degrees.

[0031] The ball-slot wheel 5 is installed above the frame opening through a vertical shaft 6, and a plurality of semispherical ball cavities are uniformly provided on the outer periphery surface of the ball-slot wheel 5. The ball cavity is a virtual structure, is provided on the outer circular surface of the ball-slot wheel 5, is in the shape of a spherical cap, has a depth slightly greater than the radius of the ball, and has a short-lip structure formed at the outer edge of the entrance. The short lip slightly protrudes outward to form a limiting action on the ball.

[0032] In some embodiments, the ball-slot wheel 5 is a cylindrical wheel body, and the wheel body is fixed on the vertical shaft 6 through a key connection. The second dial 8 is connected to the output end of the second motor 7, the second motor 7 drives the second dial 8, the second dial 8 cooperates with the ball-slot wheel 5, and the ball-slot wheel 5 is driven to rotate at a constant speed through a transmission mechanism. The number of ball cavities is 8-12, which is determined according to the size of the ball and the number of frames to be filled.

[0033] Further, in order to ensure that the ball smoothly enters the ball cavity, a short section guide groove 9 is arranged between the ball-slot wheel 5 and the feeding hopper 10. The short section guide groove 9 is a virtual structure, is provided in the guide groove block 12, and is in the shape of a C-shaped curved channel. The guide groove block 12 is fixedly installed on the rack 1, the C-shaped curved channel in the guide groove block 12 is connected to the discharge opening of the feeding hopper 10 at the upper opening and is aligned with the ball cavity passing area of the ball-slot wheel 5 at the lower opening. The curvature radius of the C-shaped curved channel matches the diameter of the ball to ensure that the ball maintains a stable posture when sliding along the channel.

[0034] Further, in order to improve the accuracy of frame filling, the rotational speed of the ball-slot wheel 5 has a certain transmission ratio relationship with the rotational speed of the main shaft, and the rotational speed of the ball-slot wheel 5 is greater than the rotational speed of the indexing turntable 2. Assuming that the number of ball cavities is z and the number of balls filled in each frame is N, the angle through which the ball-slot wheel 5 rotates during each stop of the indexing turntable 2 is 360°×N / z, which ensures that N balls fall into the frame during each stop.

[0035] According to the embodiment of the present embodiment, the ball automatic frame filling device performs the following steps:

[0036] Step 1: The first motor 3 drives the main shaft to rotate at a constant speed. The pin of the driving dial 4 periodically enters the radial groove of the indexing turntable 2, making the indexing turntable 2 make intermittent rotation of 90 degrees. Each rotation moves an empty frame position directly below the discharge port.

[0037] Step 2: The second motor 7 drives the second dial 8, which drives the ball slot wheel 5 to rotate at a constant speed through the transmission mechanism. The ball in the feeding hopper 10 enters the C-shaped curved channel of the short section guide groove 9 under the action of gravity and slides into the ball mouth cavity being passed.

[0038] Step 3: When the ball mouth cavity is filled with the ball, the surface of the ball protrudes above the short lip, forming a physical barrier to the upstream ball, preventing multiple balls from entering at the same time.

[0039] Step 4: When the ball mouth cavity with the ball is transferred to the lower discharge area, the ball is separated from the ball mouth cavity under the action of gravity and directly enters the packaging frame 11.

[0040] Step 5: When a predetermined number of balls are loaded into the frame, the filling of one frame position is completed.

[0041] The ball automatic frame filling equipment of the embodiment overcomes the inaccuracy of time control or weight control counting mechanism and solves the technical problem of inconsistent frame filling quantity because it uses the rigid counting mechanism of the ball slot wheel 5, each ball mouth cavity can only accommodate one ball, and the number of frame filling is accurately controlled by the rotation angle of the ball slot wheel 5.

[0042] The equipment overcomes the instability of frame position positioning and solves the technical problem of inaccurate frame position alignment because it uses the outer groove Geneva mechanism to achieve the precise intermittent rotation of the indexing turntable 2, and the rotation angle is fixed at 90 degrees each time.
