Description

Technical Field

[0001] This invention relates to the field of transportation technology, and specifically to a multi-purpose horizontal handling device for a large-size surface grinding pallet. Background Technology

[0002] Large-size glass surface grinding typically involves attaching an adsorption pad to the surface of a glass tray. The adsorption pad holds the glass substrate and moves it between grinding machines for surface grinding. If an abnormality occurs during grinding, the broken glass on the adsorption pad surface must first be cleaned, then the surface of the adsorption pad should be rinsed thoroughly with water. The adsorption pad should be manually inspected for damage. If the adsorption pad surface is intact, it can be put back into production. If the adsorption pad is damaged, it must be transported a long distance to the auxiliary room for re-attaching.

[0003] As can be seen from the above description, the surface grinding process requires transmission between roller conveyors, the processing process requires transfer between machine stations, and the preparation process requires pallet hoisting or handling. If any of these processes are abnormal, it is inevitable that the pallet will collide or deform. The pallet needs to be inspected offline, and it can be put back on the machine after confirming that there are no abnormalities.

[0004] Large-size surface grinding trays are characterized by their large size and weight, requiring protection during handling. Specialized handling equipment needs to be developed to meet the process requirements of connecting to offline cleaning trays on production lines and for long-distance offline transport from production lines to the preparation room. Summary of the Invention

[0005] The purpose of this invention is to solve the problems mentioned above in the background art, and to propose a multi-purpose horizontal handling device for large-size surface grinding trays.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A multi-purpose horizontal transport device for large-size surface grinding pallets includes an electric tractor and a pallet transporter. The electric tractor is used to tow the pallet transporter. The pallet transporter includes an equipment frame and a water tray. The water tray is disposed above the equipment frame and is rotatably connected to the equipment frame via a flipping mechanism. The flipping mechanism is used to drive the water tray to flip on the equipment frame.

[0008] The water tray is equipped with a pallet. Guide rollers for guiding during transmission and limiting during flipping are rotatably connected to both sides of the pallet on the water tray. A transmission roller for supporting and driving the pallet is installed on the water tray near the guide rollers. Both sides of the upper end face of the water tray are raised upward to form an angle, and a drain outlet is opened through the angle.

[0009] As a further aspect of the present invention: auxiliary guide wheels are installed on both sides of the end of the equipment frame away from the electric tractor.

[0010] As a further aspect of the present invention: the flipping mechanism includes a flipping motor and a rotating shaft, the rotating shaft rotates on the equipment frame through a flipping bearing seat, and the rotating shaft is connected to the output end of the flipping motor.

[0011] As a further aspect of the present invention: a tilting gearbox is also installed on the device frame, and the rotating shaft is connected to the tilting motor through the tilting gearbox.

[0012] As a further aspect of the present invention: the electric tractor is connected to the pallet transport vehicle via a traction ring.

[0013] As a further aspect of the present invention: a limiting block is fixed on one end of the water tray near the electric tractor.

[0014] As a further aspect of the present invention, an electrical control mechanism is also provided on the equipment frame, which is used to control the pallet truck.

[0015] As a further aspect of the present invention: the electrical control mechanism includes a control box and a wired operation controller, the wired operation controller being electrically connected to the control box, and the wired operation controller being used to control the flipping motor and the transmission roller.

[0016] The beneficial effects of this invention are as follows: This patent develops a multi-functional pallet transport vehicle with two functions. Function one connects to the production line debris cleaning station, discharges abnormal pallets from the conveyor belt, flips them over, and cleans debris or foreign objects offline, with manual inspection of the absorbent pads. Function two connects to the production line shredded board cleaning station or pallet discharge station, discharges pallets from the production line, and horizontally transports the pallets over a long distance to the preparation room for re-preparation.

[0017] Function 1: The transport vehicle docks with the production line's debris cleaning station. When a grinding abnormality occurs, the abnormal pallet is horizontally discharged from the debris cleaning station to the pallet transport vehicle, detaching from the pallet conveyor belt. The operator flips the pallet and performs offline cleaning and inspection of its surface. The pallet is then flipped to a 60-degree angle with the horizontal, and debris or foreign objects are manually removed from the surface of the absorbent pad. After cleaning, the absorbent pad surface is rinsed with clean water and inspected. If the absorbent pad is intact, it is reinstated for production. If the absorbent pad is abnormal and cannot be reinstated, it proceeds to Function 2.

[0018] Function Two: The transport vehicle docks with the production line's scrap cleaning station or pallet discharge station, horizontally discharging abnormal pallets into the transport vehicle for long-distance horizontal transport from the production line to the preparation room for re-processing. Alternatively, the re-processed pallets can be transported from the preparation room to the production line's scrap cleaning station or pallet discharge station for re-entry into the production line.

[0019] The bottom of the transport vehicle features multiple rows of horizontal rollers that effectively grind the pallet on the support surface during transport, preventing pallet deformation. The horizontal rollers utilize an external rotor design, allowing for forward, reverse, and braking movements, corresponding to the three actions of pallet loading, pallet unloading, and horizontal braking. Two rows of guide wheels on each side of the transport vehicle prevent lateral slippage of the pallet while fulfilling its functional requirements. Attached Figure Description
