The weighing sensor 21 transmits the weight data to the display device (not shown) and the control device (not shown) by wireless transmission or wired transmission.

[0032] There is further a control device, which can control the start-up and operation of the drive motor and the electromagnet 35, and the control device is connected to the weighing sensor 21 and the display device signals in the form of electrical signals.

[0033] The electromagnetic flip device 3 is arranged on the weighing device 2, and includes a flip mounting plate 31, an electromagnetic device 32, a hinge 33, a connecting plate 34 and a limit device; the flip mounting plate 31 is fixed on the weighing end 22 at the top of the front end of the weighing sensor 21; the electromagnetic device 32 is arranged on the electromagnet 35 and the armature 36 on the rear end of the flip mounting plate 31, and the limit device is arranged on the front end of the flip mounting plate 31;

[0034] The tray device 4 is arranged above the weighing device 2, and includes a tray mounting plate 41. A tray 42 is fixed on the top of the tray mounting plate 41. The bottom of the tray mounting plate 41 is hinged to the flip mounting plate 31 through a hinge 33. The armature 36 is fixed to the bottom of one end of the connecting plate 34. The end of the connecting plate 34 away from the armature 36 is connected to the bottom of the tray mounting plate 41, so that the armature 36 can be located above the electromagnet 35.

[0035] Furthermore, the tray mounting plate 41 is an inverted L-shaped structure, wherein the top horizontal section is fixed to the bottom of the tray 42 , and the bottom vertical section is hinged to the flip mounting plate 31 via a hinge 33 .

[0036] Furthermore, the limiting device includes a limiting mounting plate 43 and a limiter 44, and one end of the limiting mounting plate 43 is fixed to the front end of the flip mounting plate 31;

[0037] Furthermore, a bending section 45 is provided on the other end of the limiting installation plate 43 to extend downward, and a limiting fixing hole 46 for fixing the limiter 44 is provided on the bending section 45 .

[0038] Furthermore, a first sensor gasket 25 is disposed between the weighing mounting bracket 24 and the bottom fixed end 23 of the weighing sensor 21 .

[0039] Furthermore, a second sensor gasket 26 is provided between the flip mounting plate 31 and the weighing end 22 at the top of the front end of the weighing sensor 21 .

[0040] The principle of this embodiment is: when the tray 42 is horizontal, the control device (not shown) controls the electromagnet 35 and the armature 36 to be in a magnetic attraction state. At this time, the logistics operation trolley is in a state to be sorted and weighed. When the control device controls the motor (not shown) to drive the logistics operation trolley to slide to the set receiving goods position (not shown), the tray 42 is just located in the automatic falling area of ​​​​the unsorted and unweighed goods.

[0041] When the goods fall into the pallet from a height, the weighing device 2 in the operating bracket 1 starts to calculate the weight of the goods before and after falling into the pallet. The weight information of the goods is displayed on the display device through data transmission and is also sent to the control device. The control device then performs a sorting procedure, and controls the electromagnet 35 and the armature 36 through the control device to eliminate the magnetic attraction between the electromagnet 35 and the armature 36, so that the pallet 42 can be flipped forward along the hinge 33 due to the gravity of the goods themselves, thereby flipping the goods in the pallet 42 to the corresponding position.

[0042] A reset area is provided at one end of the slide rail for resetting the tray 42. A reset guide rod 51 gradually extending upward along the moving direction and a guide rod bracket 52 supporting the reset guide rod 51 are provided on the inner side of the slide rail portion of the area; the lowest position height of the reset guide rod 51 is lower than the height of the tray 42 after flipping, and the highest position height is not higher than the height of the tray 42 before flipping.

[0043] When the logistics operation trolley needs to flip and reset the tray 42 after completing the sorting work, the control device controls the motor to pull the trolley to slide to the reset position area. At this time, the control device controls the electromagnet 35 to be energized to generate a magnetic attraction, and the flipped tray 42 is in a low position. After the bottom of the tray 42 contacts the upper surface of the reset guide rod 51 at the lowest position and continues to slide along the reset guide rod 51 while flipping upward to reset, at this time, due to the upward reset and flipping of one end of the tray 42, the armature 36 fixed at the bottom of one end of the connecting plate 34 is getting closer and closer to the top of the electromagnet 35. Finally, due to the magnetic attraction of the electromagnet 35, the armature 36 drives the tray to be firmly sucked by the electromagnet 35, and the tray 42 is completely flipped and reset.

[0044] At this time, the logistics operation trolley returns to the state of waiting for sorting and weighing, and can continue the weighing and sorting work through the control device.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the technical solution of the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
