[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely explain the technical solutions in the embodiments of the present invention. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other in the absence of conflict, and the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0028] See also Figure 1-6 This embodiment describes an intelligent logistics device for a tubular product production line, which includes an AGV trolley 1 and a connecting device. The connecting device includes a trackless follower trolley 10 and a fixed support frame 11. The trackless follower trolley 10 and the fixed support frame 11 are arranged at intervals on the same axis. The AGV trolley 1 is arranged in the interval between the trackless follower trolley 10 and the fixed support frame 11. The AGV trolley 1 includes a body 2 and a load device, and the load device is connected to the body 2.

[0029] When the blank 12 is transported to the end along the axial conveyor chain, it passes through the fixed support frame 11 and the trackless follower trolley 10 in turn, so that the blank 12 moves above the fixed support frame 11 and the trackless follower trolley 10. At this time, the trackless trolley 10 moves away from the fixed support frame 10 as the blank 10 moves until the blank 12 is completely moved to the top of the fixed support frame 11 and the trackless follower trolley 10. Then the AGV trolley 1 moves between the trackless trolley 10 and the fixed support frame 11 and is directly below the blank 12. At this time, the loading device on the AGV trolley rises to support the blank 12. After the blank 12 is stable, the AGV trolley 1 moves laterally to remove the blank 12 on the AGV trolley 1.

[0030] The loading device includes a metal bracket 3, a lifting mechanism 4, a guide mechanism 5 and a weighing sensor 6. The loading device is used to achieve self-locking of the blank 12 under the action of gravity, and to confirm whether it is unloaded and whether the load clamping state is stable. At the same time, the weighing data is fed back to the system for recording. The lifting mechanism 4 is arranged inside the vehicle body 2. When the blank 12 reaches above the AGV trolley 1, the lifting mechanism 4 rises upward and supports the blank 12. The top of the lifting mechanism 4 is connected to the metal bracket 3. The metal bracket 3 is arranged above the vehicle body 2. The guide mechanism 5 is symmetrically arranged on both sides of the lifting mechanism 4. The guide mechanism 5 is used to ensure the stability of the lifting mechanism 4. The top of the guide mechanism 5 is connected to the metal bracket 3. The weighing sensor 6 is arranged inside the metal bracket 3.

[0031] After the demolding equipment stops, the AGV trolley 1 moves to the middle of the trackless follower trolley 10 and the fixed support frame 11 and is at the bottom of the middle of the blank 12. The jacking mechanism 4 on the AGV trolley 1 rises to realize automatic clamping and positioning of the blank 12. At the same time, the blank 12 triggers the weighing sensor 6 inside the metal bracket 3, and transmits the weight data of the blank 12 back to the system to count the weight of the blank 12. At the same time, the AGV trolley 1 moves the blank 12 to the next workstation.

[0032] Two loading devices are symmetrically arranged in the horizontal direction inside the vehicle body 2. By arranging the two loading devices, the stability of the slender tubular blank 12 during the transportation process is ensured.

[0033] A floating clamp 8 is provided on the top of the metal bracket 3 , and an elastic protective layer 9 is provided on the surface of the floating clamp 8 . The elastic protective layer 9 prevents the weighing sensor 6 from directly contacting the blank 12 , thereby reducing the service life of the weighing sensor 6 .

[0034] The floating clamp 8 includes two arc support plates, a spring and a pin. The outer side of the arc support plate is connected to the metal bracket 3 through a spring. The two arc support plates are connected through a pin. An elastic protective layer 9 is provided on the upper surface of the arc support plate.

[0035] A first lifting mechanism 16 is provided on the top of the fixed support frame 11 , and a second lifting mechanism 17 and a third lifting mechanism 18 are symmetrically provided on the top of the trackless follower trolley 10 . The first lifting mechanism 16 , the second lifting mechanism 17 and the third lifting mechanism 18 are used to receive the blank 12 .

[0036] The second lifting mechanism 17 is arranged on a side close to the fixed support frame 11 , driven support rollers 13 are arranged on the top of the first lifting mechanism 16 and the second lifting mechanism 17 , and a support saddle 14 is arranged on the top of the third lifting mechanism 18 .

[0037] The rotation direction of the driven support roller 13 is consistent with the axial direction of the blank 12 , and the driven support roller 13 can rotate as the blank 12 moves axially.

[0038] A sensor 15 is provided between the second lifting mechanism 17 and the third lifting mechanism 18 , and the sensor 15 is connected to the trackless follower trolley 10 .

[0039] After the blank 12 is separated from the demoulding equipment, the blank 12 moves toward the trackless follower trolley 10 through the driven support roller 13 on the first lifting mechanism 16 provided on the fixed support frame 11. After passing the driven support wheel 13 on the second lifting mechanism 17 provided on the trackless trolley 10, the sensor 15 is triggered, and the third lifting mechanism 18 drives the support saddle 14 to rise. The support saddle 14 contacts the outer surface of the blank 12, and the trackless follower trolley 10 moves with the movement of the blank 12, so that the middle of the blank 12 is suspended.

[0040] Four wheels are provided at the bottom of the trackless follower trolley 10, and brake devices are provided on the four wheels. When the blank 12 passes over the second lifting mechanism 17, the driven support roller 13 rotates as the blank 12 moves. When the blank 12 passes the sensor 15, the third lifting mechanism 18 rises, and the support saddle 14 on the third lifting mechanism 18 contacts the outer surface of the blank 12. At this time, the brakes of the four wheels of the trackless follower trolley 10 are released, and the trackless follower trolley 10 moves backward with the blank 12 under the push of the blank 12, completing the preparation work before the AGV trolley 1 accepts work.

[0041] After the blank 12 is transported axially to the end of the demolding equipment, it first passes through the driven support roller 13 on the first lifting mechanism 16 on the fixed support frame 11. The driven support roller 13 rotates with the axial movement of the blank 12, and then passes through the driven support roller 13 arranged above the second lifting mechanism 17 installed on the top of the trackless follower trolley 10, so that the blank 12 continues to move axially. When the blank 12 passes above the sensor 15 on the trackless follower trolley 10, the sensor 15 is triggered to act, and the third lifting mechanism 18 drives the support saddle 14 to rise upward, and the support saddle 14 contacts the outer surface of the blank 12. At this time, the brakes on the four wheels of the trackless follower trolley 10 are released. Under the push of the blank 12, the trackless follower trolley 10 continues to move axially following the blank 12, completing the preparation work before the AGV trolley 1 accepts work.

[0042] The AGV trolley 1 equipped with the load tooling moves to the gap between the fixed support frame 11 and the trackless follower trolley 10, and is placed under the blank 12. The lifting mechanism 4 on the AGV trolley 1 is raised, and the stability of the lifting mechanism 4 is ensured by the guide mechanism 5. At this time, the floating clamp 8 on the metal bracket 3 is self-locked under the action of the gravity of the blank 12. At the same time, the weighing sensor 6 is used to confirm whether it is empty and whether the load clamping state is stable, and the weighing data of the blank 12 is fed back to the system for recording. At the same time, the AGV trolley 1 moves out laterally to transfer the blank 12 to the next workstation.
