A tank stacking device and a tank rotation area are configured so that each heating room can place multiple tanks in the height direction to improve production efficiency. A telescopic insulation device is configured in the heating room to facilitate the entry and exit of the AGV while ensuring the overall insulation effect of the heating room.

[0022] Example 1

[0023] In this embodiment, the system includes a heating room area 1, and a tank rotation station area 2 is provided on one side of the heating room area for rotating and adjusting the position of the tank vacuum port so that the position of the vacuum port can correspond to the position of the main machine in the heating room. The system is also provided with a tank lifting upper and lower piece station area 3 for stacking two tanks so that the two tanks can be transported at one time later.

[0028] Example 2

[0029] In this embodiment, a method for using a tank heating and vacuuming system based on an AGV transportation method is described, and the method includes the following steps: a. The first automatic guided vehicle transports the first tank into the tank rotation station area, and the tank that needs to be turned is turned by the first automatic guided vehicle; b. The first guided vehicle transports the first tank to the tank lifting and lowering station area, and the first tank is placed on the support column by the tank lifting device; c. The first automatic guided vehicle transports the second tank into the tank rotation station area, and the tank that needs to be turned is turned by the first automatic guided vehicle; d. A guided vehicle transports the second tank body to the tank body lifting and lowering workstation area, places the second tank body on the support column through the tank body lifting device, and then stacks the first tank body on the second tank body; e. The second automatic guided vehicle transports the two stacked tank bodies together to the designated heating room, and places the two workpieces on the shelves in the heating room; f. The second automatic guided vehicle exits the heating room, and the telescopic insulation device in the heating room extends to cover the ground, and heating and vacuuming work is carried out; g. After the heating and vacuuming work is completed, the second automatic guided vehicle and the first automatic guided vehicle cooperate to transport the tank body to the next process.

[0030] Preferably, in step a, the first automatic guided vehicle rotates the tank body so that the vacuum port side of the tank body can enter the heating room first, thereby achieving the purpose of corresponding cooperation between the vacuum port and the main unit of the heating room.

[0031] Furthermore, the first automatic guided vehicle is used for transporting a single tank, and the second automatic guided vehicle is used for transporting multiple tanks. The tank lifting and lowering station area is provided with a tank lifting device and a group of support columns corresponding to the tank lifting device, and the support columns are used to place the tank. The heating room area is provided with a number of symmetrically arranged heating rooms, and a main unit for heating is provided on one side of each heating room, and a shelf for placing the tank is provided in the heating room, and a retractable retractable heat preservation device is provided at the bottom of the heating room.

[0032] Example 3

[0033] In this embodiment, multiple groups of heating rooms 1 are arranged symmetrically, that is, the heating room workpiece entry and exit door is located in the middle, and the main machine parts are located on both sides. The number of heating rooms can be configured according to specific requirements, and an AGV logistics channel needs to be reserved on one side.

[0034] The tank body rotation station area 2 is used for turning the tank body. Since the vacuum port of the tank body is located on one side of the tank body, the vacuum port must be located on the main unit side of the heating room. When the direction of the tank body is opposite to the direction of the heating room to be entered, the tank body is turned at the tank body rotation station area 2.

[0035] The tank lifting upper and lower parts workstation area 3 is mainly composed of a tank lifting device 6 and a support column 7. The tank lifting device can lift the tank to a height that can ensure that two tanks can be stacked. The support column 7 is used to place the tank on the workstation.

[0036] The first automatic guided vehicle 4 is used for transporting a single tank, and its load capacity is greater than the weight of the single tank, and it has at least the functions of straight travel, lateral travel, steering, in-situ rotation, and lifting.

[0037] The second automatic guided vehicle 5 is used for transporting multiple tanks, and its load capacity is greater than the total weight of the multiple tanks, and it has at least the functions of straight travel, lateral travel, steering, and lifting.

[0038] The heating room is mainly composed of a heating room body 8, a shelf 9, a telescopic insulation device 10, and a main unit 11. The heating room body 8 has a heat insulation function, and a door is opened on one side to facilitate the second automatic guided vehicle 5 and the workpiece to enter and exit. The shelf 9 is used to place the workpiece in the heating room. Since a fixed insulation layer cannot be laid on the ground in the heating room where the second automatic guided vehicle 5 moves, a telescopic insulation device 10 is designed. When the second automatic guided vehicle 5 transports the workpiece in and out, the insulation device retracts and makes way; after the second automatic guided vehicle 5 withdraws, the insulation device extends to cover the ground to prevent heat from being lost from the ground during the heating process.

[0039] The telescopic heat-insulating device 10 is mainly composed of a heat-insulating material 12 and a rotating drive device 13 . The heat-insulating material 12 has certain flexibility and can be rolled up or unfolded to form a surface under the action of the rotating drive device 13 .

[0040] like Figure 1 As shown, there are 13 groups of heating rooms in the area, and there are AGV logistics channels between the heating rooms. When the tank is incoming, the vacuum port is on the right side of the figure. When the tank is about to enter the heating room 1-6 on the right, the process is as follows: 1) The first automatic guided vehicle 4 transports the first tank into the workstation; 2) Transport to the tank lifting upper and lower workpiece workstation area 3 and place the workpiece on the support column 7; 3) The tank lifting device 6 lifts the tank to a height that ensures that two tanks can be stacked; 4) Transport to the tank lifting upper and lower workpiece workstation area 3 and place the workpiece on the support column 7; 5) The tank lifting device 6 descends to stack the first tank onto the second tank; 6) The second automatic guided vehicle 5 moves to the tank lifting upper and lower parts workstation area 3 to lift the two stacked tanks; 7) The second automatic guided vehicle 5 transports the tank to the designated heating room and places the workpiece on the shelf 9 in the heating room; 8) The second automatic guided vehicle 5 exits the heating room, and the telescopic insulation device 10 extends to cover the ground; 9) Carry out heating and vacuuming work.

[0041] When the tank is about to enter the left side of the heating room 7-13, the process is as follows: 1) The first automatic guided vehicle 4 transports the first tank into the workstation; 2) The tank is first transported to the tank rotation station area 2 and turned by the in-situ rotation function of the first automatic guided vehicle 4; 3) Transport to the tank lifting upper and lower workpiece workstation area 3 and place the workpiece on the support column 7; 4) The tank lifting device 6 lifts the tank to a height that ensures that two tanks can be stacked; 5) The first automatic guided vehicle 4 transports the second tank into the workstation; 6) The tank is first transported to the tank rotation station area 2 and turned by the in-situ rotation function of the first automatic guided vehicle 4; 7) Transport to the tank lifting upper and lower workstation area 3 and place the workpiece on the support column 7; 8) The tank lifting device 6 descends to stack the first tank onto the second tank; 9) The second automatic guided vehicle 5 moves to the tank lifting upper and lower parts workstation area 3 to lift the two stacked tanks; 10) The second AGV 5 transports the tank to the designated heating room and places the workpiece on the shelf 9 in the heating room; 11) The second automatic guided vehicle 5 exits the heating room, and the telescopic insulation device 10 extends to cover the ground; 12) Perform heating and vacuuming work; 13) After the heating and vacuuming is completed, the above steps are carried out in reverse order and the tank is transported to the next step.

[0042] The invention has high automation degree, high site utilization rate, high safety performance, energy saving and environmental protection, and is suitable for the automated production of tank heating and vacuuming process.

[0043] The above content is a further detailed description of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to the above descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the scope of protection of the present invention.
