[0028] The present application is applied to a multi-layer infusion bag sorting machine, which has multiple layers of sorting units, and each layer of sorting units performs different sorting operations on different infusion bags. One side of the sorting unit has a lifting mechanism, and the present application uses the lifting mechanism to travel back and forth between the infusion bag delivery outlet and the sorting units of different layers, and correctly transports the infusion bags loaded thereon to the sorting units of the corresponding number of layers for unloading.

[0029] The present invention is further described in detail below in conjunction with specific embodiments:

[0030] like Figure 1 As shown, a mobile vehicle for infusion sorting includes a traveling assembly 1 and a loading and unloading assembly 6. The traveling assembly 1 is used to drive the vehicle to run, and the loading and unloading assembly 6 is used to carry the infusion bag and perform loading and unloading operations at the loading and unloading station.

[0031] like Figure 2As shown, the walking assembly 1 includes a chassis 2, on which a wireless communication module, a stepper motor 3 drive module and a magnetic Hall sensor 4 are arranged. Among them, the wireless communication module is used to receive the signal of the host computer and transmit the signal to the single-chip microcomputer, and the single-chip microcomputer controls the operation of the stepper motor 3 drive module. Among them, the stepper motor 3 drive module includes a pair of stepper motors 3, and the pair of stepper motors 3 are respectively arranged on the front axle and the rear axle, and are respectively connected to a pair of front wheels and rear wheels, so as to generate a stronger driving force. The magnetic Hall sensor 4 will detect the parking position to ensure the parking accuracy when parking, so as to ensure that the infusion bag reaches the designated loading and unloading station. And a 60W lithium battery pack 5 is provided to provide the vehicle with the energy required for operation.

[0032] The loading and unloading assembly 6 includes a loading plate 7 for carrying the infusion bag. The loading plate 7 is slidably connected to a loading and unloading drive mechanism 8 fixed on the chassis 2, and is tilted or lifted under the action of the loading and unloading drive mechanism 8.

[0033] In this embodiment, the loading and unloading drive mechanism 8 is provided as a pair, and the execution ends of the pair of loading and unloading drive mechanisms 8 are respectively provided on both sides below the loading plate 7. Figure 3 As shown in FIG. 1 , when one of the loading and unloading drive mechanisms 8 is activated, the loading plate 7 performs a flipping motion with the execution end of the other loading and unloading drive mechanism 8 that is not activated as the axis. Figure 4 As shown, when a pair of loading and unloading drive mechanisms 8 act synchronously, the carrier plate 7 can be lifted up. The heights of the discharge ports of different infusion bags are not necessarily uniform, and the lifting and lowering movement of the carrier plate 7 under the action of the pair of loading and unloading drive mechanisms 8 can adapt to discharge ports of different heights, thereby preventing the infusion bag from falling onto the carrier plate 7 and being damaged due to the discharge port being too high.

[0034] A slide groove 9 is fixed at the bottom end of the loading plate 7. The slide groove 9 is provided in a pair and is respectively located in the rotation plane of the execution end of a pair of loading and unloading drive mechanisms 8 and slides with the execution end. Figure 5 As shown, the loading and unloading drive mechanism 8 includes a driver 81. In this embodiment, the driver 81 is a steering gear. The output shaft of the steering gear is radially fixed with a flip arm 82. The end of the flip arm 82 away from the steering gear is vertically fixed with a round shaft 83. The round shaft 83 penetrates the chute 9 and slides in the chute 9. When performing the unloading action, the driver 81 drives the flip arm 82 to rotate around the output shaft, so that the round shaft 83 slides from one end of the chute 9 to the other end in the corresponding chute 9. Figure 6 As shown, at this time, the carrier plate 7 reaches the maximum tilt angle, and the line connecting the circular shaft 83 and the output shaft is perpendicular to the carrier plate 7, so that the carrier plate 7 is in a self-locking state at this time. Even if the servo stops outputting power, the carrier plate 7 will not fall back due to the weight of the infusion bag.

[0035] like Figure 4As shown, folding arms 10 are provided at both ends of the loading board 7 along the length direction, and fixed blocks 101 are hinged at both ends of the folding arms 10, and the folding arms 10 are hinged to the bottom surface of the chassis 2 and the loading board 7 through the fixed blocks 101, so that the folding arms 10 can be extended within the flipping plane of the loading board 7, providing guidance when the loading board 7 is loaded and unloaded and lifted and lowered, thereby preventing the loading board 7 from moving along the length direction.

[0036] like Figure 7 As shown, guardrails 71 are fixed at both ends of the upper surface of the carrier plate 7 along the length direction to block the infusion bag. A plurality of anti-sticking frames 72 are fixed in parallel in the middle, and the top of the anti-sticking frame 72 is configured to be arc-shaped and provided with a frosted coating to imitate the infusion bag being transported. When the infusion bag is placed on the carrier plate 7, a part of the lower surface of the infusion bag is carried on the anti-sticking frame 72, and the other part is suspended between two adjacent anti-sticking frames 72. Such a configuration prevents the infusion bag from being closely attached to the flat upper surface of the carrier plate 7, thereby preventing adhesion from occurring and causing the infusion bag to be unable to slide down by gravity during unloading.

[0037] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the scope of protection of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the present invention.
