Technical Field
The invention relates to a warehousing technology, in particular to a warehousing goods transportation robot and a loading method thereof.
Background
An Automated Guided Vehicle (AGV) is also commonly referred to as an AGV. The present invention relates to a transport vehicle equipped with an electromagnetic or optical automatic navigation device, capable of traveling along a predetermined navigation route, and having safety protection and various transfer functions. The industrial application does not need a driver's transport vehicle, and a rechargeable storage battery is used as a power source of the industrial application. The path and behavior of the device can be controlled by a computer.
In the traditional construction scheme of matching the three-dimensional library used by the AGVs, a material box robot scheme is mostly adopted for construction, and as the prior art has proposed, a material box carrying AGV, a carrying method and an SMT production line automatic docking system (patent publication No. CN 107813882A) comprise: the feeding and discharging device comprises a vehicle body, a feeding and discharging device arranged on a material box of the vehicle body and a control center, wherein the control center is used for controlling the feeding and discharging device to perform corresponding actions, the feeding and discharging device is arranged behind the vehicle body, the feeding and discharging device comprises a material box conveying mechanism used for receiving and conveying the material box, and the receiving and conveying direction of the material box conveying mechanism is parallel to the running direction of the vehicle body.
However, the bin robot is mainly characterized in that the car body moving part and the lifting part of the bin robot are integrated into a whole. Therefore, the adaptive height of the shelf is limited to the lifting range of the robot, so that the design height of the warehouse shelf is limited, and the robot is not economical even if the lifting range of the robot is intentionally increased, and more potential safety hazards are brought in transportation due to an excessively high lifting mechanism.
On the other hand, there is also an AGV with a function of climbing a rack, such as an automatic guided vehicle and a storage system (patent publication No. CN 110035961A) proposed in the prior art, wherein the automatic guided vehicle can climb along the rack, the rack includes a rack body and a first engaging member, a passage for the automatic guided vehicle to travel is provided between two adjacent racks, and the first engaging member is located on a side of the rack body close to the passage. The automatic guide transport vehicle comprises a frame, a climbing device and a telescopic driving device. The climbing device comprises a telescopic connecting piece, a second meshing piece and a climbing driving mechanism, the second meshing piece and the climbing driving mechanism are connected with the telescopic connecting piece, the telescopic connecting piece can move for a preset distance relative to the rack, so that the second meshing piece is meshed with the first meshing piece, the climbing driving mechanism can drive the second meshing piece to rotate, the automatic guided transport vehicle climbs along the first meshing piece, and the automatic guided transport vehicle comprises two climbing devices. The telescopic driving device can drive the telescopic connecting pieces of the two climbing devices to move for a preset distance in opposite directions respectively.
However, such a rack climbing robot is mainly characterized by having both horizontal movement characteristics and rack climbing capability of the AGV, and is designed to be an integral structure, and although the problem of rack height limitation is solved, the body self weight of the robot integrated with the characteristics of the conventional AGV is relatively heavy, so that a mechanism for providing water translation capability during load climbing becomes burdensome, consumes a part of load carrying capacity, and therefore, needs to provide higher climbing force during load carrying, and is not economical.
In addition, the prior art stereo garage and the robot solution thereof have a common disadvantage that the capacity can not be allocated freely because the capacity can not be supported off the task in the middle after the freight command is executed and the goods are received.
