[0053] The present application provides a rotating dial for use in a vending machine, an automatic delivery shelf or a delivery device 10 of a display cabinet, the delivery device 10 comprising a tray 11, a closed curved channel 12 arranged on the tray 11, a plurality of delivery assemblies 13 arranged along the closed curved channel 12 and abutting each other, and a driving assembly 14 arranged below the closed curved channel 12; a plurality of closed curved channels 12 of different specifications are arranged on the tray 11 to adapt to the delivery of goods of different sizes. The multi-layer tray 11 is arranged in the cabinet of the vending machine. The bottom center of the delivery assembly 13 is provided with a center column; the center column moves along the center line of the closed curved channel, the driving assembly 14 comprises a rotating dial 20 arranged below the closed curved channel 12 and a driving member for driving the rotating dial 20 to rotate; the rotating dial 20 drives the center column to move by rotating, so that the delivery assembly 13 moves circularly along the closed curved channel 12; the rotating dial 20 comprises a three-section clamping groove 22 arranged symmetrically along the center thereof, and at least one center column is clamped in the clamping groove 22; when the rotating dial 20 rotates, the center columns of adjacent delivery assemblies 13 enter the next clamping groove 22 of the rotating dial 20. The driving mechanism drives the delivery assembly 13 to continuously and smoothly deliver. The delivery assembly 13 comprises a guide bearing wheel 131 and a rotating drum arranged on the guide bearing wheel 131, and the rotating drum is provided with an opening on one side. The outer circumferential surfaces of adjacent guide bearing wheels 131 are arranged abutting each other, and goods are placed in the rotating drum. Preferably, the pulley of the guide bearing wheel 131 is 4, arranged symmetrically along the center of the rotating drum, and the outer diameter distance of the two pulleys is adapted to the width of the closed curved channel 12. The driving mechanism drives the rotating dial 20 by using a motor.

[0058] In one embodiment, L≥2R, which ensures that the adjacent center column can smoothly enter the card slot 22, the center column of the delivery assembly 13 enters the card slot 22 of the rotating paddle 20, and the rotating paddle 20 pushes the center column. Preferably, when L=2R, A=2R / 1.732-R=0.155R. At this time, the adjacent center column is just entering the card slot 22, and the other center column is just leaving the card slot. The delivery assembly 13 on the rotating channel can smoothly move in sequence under the driving of the motor, ensuring the continuity of delivery, and the smaller the gap between the channels, the better, which facilitates the placement of more delivery assemblies 13. Moreover, during the rotation of the motor, the rotating paddle 20 can continuously push the delivery assembly 13, ensuring that the contact between the rotating paddle 20 and the delivery assembly 13 is continuous. When the motor rotates, the delivery assembly 13 moves in the slide according to the trajectory, and when the motor stops, neither the rotating paddle 20 nor the delivery assembly 13 can move.

The bottom of the delivery assembly is provided with four guide bearing wheels, and the maximum distance between the left and right guide bearing wheel grooves is C. The width of the slide is C, and the center of the delivery assembly has a center column. The sliding track of the center column is the middle track, and the paddle pushes the center column to move. The center of the rotating paddle (the center) coincides with the center of the closed curved channel (the center of the semicircular slide). This ensures the continuity of the movement of the delivery assembly, reduces the movement error and the impact noise caused thereby, etc.

[0066] The outer length of the slide is Hout; the inner length of the slide is Hin; and the length of the center line of the slide is Hmid;

[0067] The width of the moving track of the delivery assembly 13 in the slide is Wgoods;

[0068] The outer width of the slide is Wout;

[0071]

[0072]

[0073] H3=R+A-H5

[0074]

[0075]

[0076] Hout = Hmid + C

[0077] Hin = Hmid - C

[0078] Win = 2(A + R) - C
