[0003] To better achieve sorting, existing technologies have proposed the idea of ​​enabling the tilting assembly of the sorting cart to rotate horizontally relative to the cart frame. Correspondingly, how to drive the horizontal rotation of the tilting assembly without setting a power source on the sorting cart has become an urgent technical problem to be solved.

[0026] Example 1

[0027] The sorting drive mechanism disclosed in this utility model will now be described in conjunction with the accompanying drawings, as shown below. Figure 1 Appendix Figure 2 As shown, it includes a drive arm 100, which includes a first external working surface 110 and a second external working surface 120 that are obtuse-angled and connected to each other. The drive arm 100 is horizontally rotatably connected to the mounting base 300 about a vertical axis 200. The drive arm 100 is connected to a rotary drive device 400 that drives it to rotate about the vertical axis 200. The rotation angle of the drive arm 100 does not exceed 45°.

[0028] For details, see attached. Figure 3 As shown, the drive arm 100 includes a vertical plate 130, which includes a first part 131 and a second part 132 bent at an obtuse angle. The length of the first part 131 is greater than that of the second part 132. For example, the length of the first part 131 is about twice the length of the second part 132. The side of the first part 131 facing away from the rotary drive device 400 is the first external working surface 110, and the side of the second part 132 facing away from the rotary drive device 400 is the second external working surface 120.

[0029] The lower side of the vertical plate 130 is bent at 90° to form a bent portion 140. The bent portion 140, the first external working surface 110, and the second external working surface 120 are distributed on both sides of the vertical plate 130, and the bent portion 140 is connected to the vertical shaft 200. To avoid the bent portion 140 contacting the mounting base 300 and affecting the rotation of the drive arm 100, a through hole is formed in the bent portion 140. The vertical shaft 200 passing through the through hole is formed on the base. The vertical shaft 200 includes a round shaft matching the diameter of the through hole and a pad located below the round shaft. The bent portion 140 is supported on the pad. The vertical shaft 200 can be made of materials such as polytetrafluoroethylene and can be fixed to the mounting base 300 by feasible methods such as screwing, gluing, or snap-fitting. Meanwhile, in order to ensure that the bent portion 140 does not separate from the vertical shaft 200, the connecting plate 150 on the drive arm 100, which is connected to the telescopic shaft 410 of the rotary drive device 400, is inserted into the notch at the end of the telescopic shaft 410.

[0030] The rotary drive device 400 can employ different components as needed, such as a cylinder or an electric cylinder. Preferably, the rotary drive device 400 is an electromagnet. The telescopic shaft 410 of the electromagnet is normally extended and retracts when energized. The telescopic shaft 410 of the electromagnet is connected to the first end of the drive arm 100, which is far from the second external action surface 120. When the telescopic shaft 410 is extended, it is perpendicular or substantially perpendicular to the first external action surface 110 (substantially perpendicular means that the angle between the axis of the telescopic shaft 410 and a straight line intersecting the first external action surface 110 is, for example, within the range of 89°-90°). At this time, the second external action surface 120 and the rotary drive device 400 are biased towards the same side of the first portion 131. When the telescopic shaft 410 retracts, the telescopic shaft 410 is perpendicular or substantially perpendicular to the second external action surface 120, and the first external action surface 110 is closer to the rotary drive device 400 relative to the second external action surface 120.

[0031] As attached Figure 3 As shown, the upper side of the vertical plate 130 is bent to form the connecting plate 150. A strip hole 151 is provided at the connecting plate. The telescopic shaft 410 is connected to the drive arm 100 through a connecting pin 500 passing through the strip hole 151. The extension direction of the strip hole 151 is consistent with the extension direction of the first external working surface 110.

[0032] The rotation angle of the drive arm is preferably between 10° and 30°, depending on the specific needs.

[0033] Furthermore, as shown in the attached document. Figure 3 As shown, in order to achieve the tilting of the tilting assembly, a tilting drive 600 located upstream of the drive arm 100 is also provided on the mounting base 300. The tilting drive 600 is rotatably mounted on the mounting base 300 about a horizontal axis 700, which is perpendicular to the telescopic axis 410 of the rotary drive device 400. The tilting drive 600 is connected to the tilting drive device 800 that drives it to rotate about the horizontal axis 700.

[0034] The horizontal shaft 700 is disposed between the two support plates 310 of the mounting base 300. The tilting drive component 600 includes two shaft connecting pieces 610 connecting the horizontal shaft 700, located between the two support plates 310. The tilting drive component 600 also includes a lifting inclined plate 620 at its top and a drive connecting piece 630 at its lower side. The lifting inclined plate 620 and the drive connecting piece 630 are located on opposite sides of the tilting drive component 600, while the shaft connecting pieces 610 and the drive connecting piece 630 are located on the same side. The drive connecting piece 630 is connected to the telescopic shaft of the tilting drive device 800 via a connecting shaft 640 parallel to the horizontal shaft 700 and a transmission plate 900. The tilting drive device 800 is preferably an electromagnet, but other feasible devices are also possible. Normally, the telescopic shaft 410 of the electromagnet extends, causing the flipping drive 600 to be in an inclined state. When the electromagnet is energized, the flipping drive 600 is straightened, and the rollers on the sorting trolley are lifted upward as they pass the lifting ramp 620, thereby realizing the flipping of the flipping assembly.

[0035] Example 2

[0036] This embodiment discloses another structure for a sorting drive mechanism that can achieve the same function. In this embodiment, as shown in the attached diagram... Figure 4 Appendix Figure 5 As shown, the sorting drive mechanism also includes the drive arm 100, which includes a first external working surface 110 and a second external working surface 120 that are obtuse angled and connected to each other.

[0037] Unlike Embodiment 1, this embodiment no longer drives the drive arm 100 to rotate horizontally, but instead drives it to move horizontally. Correspondingly, the drive arm 100 is connected to a translation drive device 001 that drives it to translate along a direction perpendicular to the second external working surface 120. The translation drive device 001 is mounted on the mounting base 300. In this case, the second external working surface 120 of the drive arm 100 remains perpendicular to the telescopic shaft 410 of the translation drive device. Furthermore, the drive arm 100 can be directly mounted on the telescopic shaft 410 of the translation drive device, or it can be mounted on the mounting base 300 via the guide rail assembly 002.
