Technical Field

[0001] The invention relates to an automatic loading and unloading transport trolley with an anti-overturning function, belonging to the field of automated logistics transportation. Background Art

[0002] The stamping production line in the automobile stamping workshop is usually located at a certain distance from the material warehouse, and the stacked materials need to be transferred from the material warehouse area to the destacking trolley at the head of the stamping line for stamping production. Since the weight of the stacked materials is generally around 10 tons, the rated load of the laser navigation AGV forklift on the market is generally within 2 tons, which is not competent for the automatic transfer of the stacked materials. At present, the loading method of the stamping production line at home and abroad is still manually driven by forklifts. Specifically, the manually driven forklift takes the materials in the material warehouse area, then transports the stacked materials to the head of the stamping line, and then places the stacked materials on the destacking trolley. This method is inefficient and slow, which seriously affects the improvement of the automation level of automobile stamping workshops. Summary of the invention

[0018] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-Figure 7 As shown, the present invention provides an automatic loading and unloading material handling trolley with an anti-overturning function, including a telescopic fork 1, an AGV trolley 2 and a clamping device 3. The telescopic fork 1 includes a base 101, a driving device 102 and a material fork 103. The base 101 is installed on the upper part of the AGV trolley 2 by bolts, and the driving device 102 and the material fork 103 are installed on the base 101. The driving device 102 drives the material fork 103 to telescope unidirectionally or bidirectionally to take and place stacked materials; the clamping device 3 is installed at the bottom of the AGV trolley 2, and is used to lock the AGV trolley 2 when the material fork 103 takes and delivers materials to prevent the trolley from overturning.

[0020] The driving device 102 includes a motor, a reducer and a brake, and the material fork 103 can be automatically extended and retracted under the action of the driving device.

[0021] The AGV trolley 2 has electromagnetic navigation or laser navigation functions and can automatically run along a designated route. The carrying capacity of the AGV trolley 2 is greater than 5T.

[0022] The clamping device 3 includes a clamping body 301 and a clamping head 302. The clamping body 301 is installed at the bottom of the AGV trolley 2 by bolts. The clamping head 302 can be extended, rotated and clamped. In the unclamped state, the clamping head 302 retracts into the clamping body 301. When the AGV trolley 2 runs to the loading and unloading position, a T-shaped hole is provided on the ground just below the clamping head 302. The control system issues a clamping command, and the clamping head 302 first extends to the clamping position and reaches the inside of the T-shaped hole on the ground. Then, the clamping head 302 rotates a certain angle and retracts to clamp. When the material fork 103 is picking up and placing materials, the clamping device 3 needs to be in a clamping state to prevent the AGV trolley 2 from overturning due to excessive overturning torque.

[0023] The telescopic fork 1 is provided with one or more sets.

[0024] The clamping device 3 is provided with at least two sets and is installed at the bottom of the AGV vehicle.

[0025] Working process: When the material fork 103 completes the material picking in the material storage area, the AGV trolley 2 automatically transports the stacked materials from the material storage area to the vicinity of the first destacking trolley of the stamping line. The material fork 103 transfers the stacked materials from the AGV trolley 2 to the destacking trolley again, and then the AGV trolley 2 automatically runs to the stacking area again to carry out the next cycle.

[0026] When the AGV trolley 2 runs to the loading and unloading position, a T-shaped hole is provided on the ground just below the clamping head 302. The control system issues a clamping command, and the clamping head 302 first extends to the clamping position and reaches the inside of the T-shaped hole on the ground. Then, the clamping head 302 rotates a certain angle (>30°) and then retracts for clamping to prevent the overturning torque from being too large and causing the AGV trolley 2 to overturn. When the clamping head 302 is not clamped, it is in a retracted state and does not affect the operation of the AGV trolley 2.

[0027] The AGV trolley of the present invention has a laser or electromagnetic navigation function with high navigation accuracy, and can realize automatic transportation without human intervention; a telescopic fork is used for loading and unloading, and has an automatic loading and unloading function; a clamping device can prevent the AGV trolley from overturning due to excessive overturning torque during loading and unloading.

[0028] The present invention has a simple structure and a high degree of automation. It can realize automatic loading and unloading and automatic transportation of materials from the material storage area of ​​the automobile stamping workshop to the small workshop where the materials are first depalletized on the stamping production line, realize unmanned production, improve production efficiency, reduce production costs, and has the characteristics of high safety and high efficiency.

[0029] The above embodiments of the present invention are merely illustrative and not exclusive, and all modifications within the scope of the present invention or equivalent to the scope of the present invention are encompassed by the present invention.
