[0021] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0022] like Figure 1 and Figure 2 As shown, a truss destacking system is used to simultaneously complete weighing operations during material transfer. It includes a weighing conveyor line 1, and a loading section 2 is correspondingly provided at one end of the weighing conveyor line 1 for supplying materials to the weighing conveyor line 1.

[0023] like Figure 3 and Figure 4 As shown, the weighing conveyor line 1 includes a weighing part 11 and a conveyor line 12, wherein the conveyor line 12 is used to convey the weighed material to the subsequent workstation. The weighing part 11 is arranged at one end of the conveyor line 12 and is used to weigh the weight of the material. The weighing part 11 has a lifting component 4 and a weighing device. When the lifting component 4 is in operation, it can perform a lifting movement perpendicular to the running direction of the conveyor line 12, so that the bottom end of the material is out of contact with the conveyor line 12, and resets after the weighing work is completed, so that the material can be conveyed by the conveyor line 12. The weighing device is arranged at the end of the lifting component 4 away from the conveyor line 12.

[0024] Specifically, the loading section 2 includes a material loading mechanism 21 and a tray loading mechanism 22. The tray loading mechanism 22 is used to supply trays 5 to the weighing conveyor line 1. When the material is on the weighing conveyor line 1, it is loaded onto the tray 5. A handling robot 3 is provided between the material loading mechanism 21 and the weighing conveyor line 1. The handling robot 3 is used to transport the material from the material loading mechanism 21 to the tray 5 on the weighing conveyor line 1.

[0025] The handling robot 3 includes a clamping portion 31 for clamping materials. Driven by a moving mechanism, the clamping portion 31 is raised and lowered and moved back and forth between the material loading mechanism 21 and the workstation where the weighing unit 11 is located. Specifically, the moving mechanism includes a transverse beam 32 arranged parallel to the conveyor line 12. A transverse track is fixed to the transverse beam 32, and a longitudinal beam 33 is slidably mounted on the transverse track. A longitudinal track is fixed to the longitudinal beam 33 in the vertical direction, and the robot slides vertically on the longitudinal track.

[0026] The lifting assembly 4 includes a fixed lifting base 41, on which a cam mechanism 42 is mounted. A lifting plate 43 for carrying the pallet 5 is connected to the end of the cam mechanism 42, which is remote from the lifting base 41. Driven by a lifting actuator, the cam mechanism 42 drives the lifting plate 43 to move upward and downward. The lifting plate 43 is also provided with a guide 44 connected to the lifting base 41 to guide the lifting plate 43 during its upward and downward movement.

[0027] The cam mechanism 42 comprises a horizontally arranged rotating shaft 421 rotatably connected to the lifting base 41. A pair of rotating shafts 421 are provided on either side of the guide 44. Two cams 422 are fixed to the center of each rotating shaft 421, and the lifting plate 43 is provided with corresponding contact wheels 423 that abut against the cams 422. Driven by the cam 422 driver, the rotating shaft 421 rotates about its axis, causing the cams 422 fixed thereto to raise or lower the contact wheels 423, in communication with the lifting plate 43. The guide 44 comprises a guide sleeve fixed to the lifting base 41 and a guide shaft extending through the guide sleeve.

[0028] In addition, to facilitate the unloading of materials, a roller machine 6 is further provided under the tray 5. The roller machine 6 comprises a roller frame 61 provided at the edge, and a pair of rollers 62 connected to the roller frames 61. The rollers 62 have axes perpendicular to the running direction of the conveyor line 12 and abut against the tray 5, facilitating the unloading of the tray 5 from one side of the conveyor line 12.

[0029] While working:

[0030] The operator supplies the pallet 5 to the weighing conveyor line 1 through the pallet loading mechanism 22 .

[0031] Then the transport robot 3 takes the material out of the material loading mechanism 21 and places it on the tray 5 .

[0032] At this time, the lifting assembly 4 is activated to lift the pallet 5 together with the material so that the pallet 5 is not in contact with the conveyor line 12, and the weighing device is used to weigh the total mass of the pallet 5, the roller 6 and the material, and then the mass of the material is obtained by subtracting the known mass of the pallet 5 and the roller 6.

[0033] Subsequently, the lifting assembly 4 drives the pallet 5 to descend, so that the pallet 5 abuts against the conveyor line 12 and is conveyed to the subsequent workstation by the conveyor line 12 .

[0034] 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 are not intended to limit the scope of protection of the present invention.
