Although this scheme will not be elaborated in detail on the cantilever fixing seat 2, the cantilever fixing seat 2 drives the cantilever shaft 3 to move up and down, which is a well-known public technology and has been well known to those skilled in the art. It is an operationally achievable structure, the bottom of the cantilever fixing seat 2 is connected to the AGV body 1, and the top of the cantilever shaft 3 is provided with a recessed groove 31, and a multi-stage lifting mechanism 4 that moves laterally along the cantilever shaft 3 is arranged in the recessed groove 31;

The end of the push-pull material rod 41 away from the lifting unit is connected to the end 411, and a photoelectric sensor 412 is embedded in the top of the push-pull material rod 41 near the end 411.

[0035] Furthermore, the multi-stage lifting mechanism 4 also includes an outer shell, which is connected to the top of the fixed seat slider 45.

[0037] Combine Figure 2As shown, in the embodiment, the lifting unit comprises a servo motor 43 fixedly installed on the fixed seat slider 45 and a linkage assembly 42 connected to the output end of the servo motor 43, one end of the linkage assembly 42 being movably connected to the push-pull material rod 41.

[0038] Further, the lifting unit further comprises a guide assembly 44, the guide assembly 44 comprising a guide rail fixedly installed on the fixed seat slider 45 and a guide rail slider fixedly connected to the push-pull material rod 41, the guide rail slider being slidingly arranged on the guide rail.

[0039] Specifically, the linkage assembly 42, the servo motor 43 and the guide assembly 44 are arranged in the inner cavity of the outer shell, so as to realize the protection of the outer shell on the lifting unit and avoid the damage of the lifting unit caused by external force factors.

[0040] Further, the guide rail installed on the fixed seat slider 45 is longitudinally installed, so as to ensure that the guide rail slider plays a guiding role on the push-pull material rod 41 when sliding on the guide rail, and ensure the stability of the lifting adjustment of the push-pull material rod 41.

[0041] In the embodiment, the linkage assembly 42 comprises a first linkage fixedly connected to the output end of the servo motor 43 and a second linkage movably connected to the push-pull material rod 41, one end of the second linkage away from the push-pull material rod 41 being movably connected to the first linkage.

[0042] Specifically, under the driving of the servo motor 43, the first linkage can drive the push-pull material rod 41 to adjust up and down through the second linkage, so as to realize the three-stage lifting or lowering action of the push-pull material rod 41 along the longitudinal direction, and promote the push-pull material rod 41 to realize the limiting of the end head 411 on the material roll 5 after lifting, so as to ensure the relative safety of the material roll 5 on the cantilever shaft 3 in the AGV walking process and avoid the risk of falling.

[0043] In combination Figure 2 and Figure 3 As shown, in the embodiment, the top of the cantilever shaft 3 is fixedly installed with two cantilever shaft sliding rails 46, the two cantilever shaft sliding rails 46 being symmetrically arranged with the trap groove 31 as the axis of symmetry, and the fixed seat slider 45 being slidingly arranged on the two cantilever shaft sliding rails 46.

[0044] Specifically, the area of the top of the cantilever shaft 3 close to the trap groove 31 is a plane, and the two cantilever shaft sliding rails 46 are fixedly installed at the plane area, so as to ensure the installation stability of the cantilever shaft sliding rails 46 and the stability of the fixed seat slider 45 when sliding.

[0045] In combination Figures 3-9 As shown, in the embodiment, the end head 411 is L-shaped, and the top end face of the end head 411 is higher than the top end face of the push-pull material rod 41.

[0046] AsFigure 5 and Figure 9 As shown, specifically, A is the end face of the cantilever shaft 3, B is the upper top surface of the cantilever shaft 3, C is the outer end face of the end head 411, D is the upper end face of the end head 411, E is the inner end face of the end head 411, F is the upper end face of the push-pull material rod 41, G is the lower end face of the push-pull material rod 41, and W is the width of the material roll 5.

[0047] In this embodiment, a screw rod for driving the fixed seat slider 45 is provided in the groove 31 , and one end of the screw rod is connected to a driving device for driving the screw rod to rotate, and the driving device is provided in the inner cavity of the cantilever fixed seat 2 .

[0048] Specifically, a structural diagram is not provided in this solution, but the screw rod and the driving device for driving the screw rod to rotate are existing public technologies in this field, which are well known and applied by those skilled in the art. Therefore, this solution does not provide a detailed description.

[0049] It should be noted that the screw thread passes through the part of the fixed seat slider 45 located in the groove 31, and when the push-pull rod 41 descends into the groove 31 and the height of the upper end surface D of the end head 411 does not exceed the upper end surface B of the cantilever shaft 3, the push-pull rod 41 will not collide with the screw that drives the fixed seat slider 45 to rotate.

[0050] The working principle and use process of this utility model:

[0051] When cutting: the initial state of the end 411 is as follows Figure 3 and Figure 4 (That is, the upper end surface D of the end head 411 does not exceed the upper end surface B of the cantilever shaft 3, and is limited to this state, and the specific position of the end head 411 is not limited), and then when the cantilever shaft 3 moves to the unloading position of the roller divider to receive the material according to the operation of the AGV body 1, the photoelectric sensor 412 can be in the detection state all the time, and when the material roll 5 is located at the front end of the cantilever shaft 3, the driving device can drive the screw rod to rotate, so that the screw rod drives the fixed seat slider 45 to move outward, prompting the fixed seat slider 45 to drive the push-pull material rod 41 to move outward. When the photoelectric sensor 412 detects the material roll 5, it can record the position of the push-pull material rod 41, and then the control system in the driving device can prompt the push-pull material rod 41 to continue to move forward L length and then stop. After the push-pull material rod 41 stops moving, the servo motor 43 can drive the connecting rod assembly 42 to rotate. After the connecting rod assembly 42 rotates, it can drive the push-pull material rod 41 and the end head 411 to lift, causing the inner end face E of the end head 411 to be located on one side of the material roll 5. Through the reverse rotation of the screw rod, when the fixed seat slider 45 moves, the end head 411 can drive the material roll 5 to move on the cantilever shaft 3, causing the front end of the cantilever shaft 3 to be empty, which is convenient for receiving the material again. After the front end of the cantilever shaft 3 has material again, the multi-stage lifting mechanism 4 can work again to pull the material roll 5 inward through the end head 411, causing the cantilever shaft 3 to carry multiple material rolls 5 at a time, realizing multi-roll unloading of the roller divider.

[0052] In the process of carrying: due to the setting of the number of downfeed, the end head 411 can not be reset after reaching a certain number, so that the end head 411 can always resist one side of the outermost roll 5 on the cantilever shaft 3, thereby realizing the relative safety of multiple rolls 5 on the cantilever shaft 3 in the process of AGV walking without the risk of falling, and multiple rolls 5 can be placed on the buffer rack after carrying, and then the cantilever shaft 3 is pulled out, so that the downfeed efficiency is significantly improved, and the number of AGV equipment investment in the production line is reduced.

[0053] In combination with Figure 7 and Figure 8 It is shown that the improved scheme is used when the roll 5 is fed: the cantilever shaft 3 can take a single roll 5 from the buffer rack and move to the roll cutting machine feeding position, and then the lifting mechanism in the cantilever fixing seat 2 makes the cantilever shaft 3 and the main machine of the roll cutting machine in place, so that the rotation of the connecting rod assembly 42 driven by the servo motor 43 makes the connecting rod assembly 42 drive the push-pull rod 41 to lift upward, so that the lower end surface G of the push-pull rod 41 is higher than or flush with the upper end surface B of the cantilever shaft 3, and during the process, the end head 411 is located between the roll 5 and the cantilever fixing seat 2 (as shown in Figure 7 , so that the movement of the fixed seat slider 45 driven by the lead screw makes the end head 411 push the roll 5 to completely separate from the cantilever shaft 3, and the roll 5 feeding process is realized.

[0054] It should be noted that: this scheme only protects the physical structure, and does not protect the device software program and control parameters, and the control system receives the signal of the photoelectric sensor 412 and sends the driving control signal, and the setting of the number of downfeed, this scheme is only a supplementary description of the feasibility and authenticity of the utility model, and the utility model does not require protection for the technology that has been known and applied by those skilled in the art.
