This is especially true for some novice drivers, whose deviations in the placement of paper rolls on the transport vehicles may be greater. As a result, even if the transport vehicles can be accurately parked in the designated position, there is still a deviation in the relative position between the paper rolls and the transport vehicles. The position of the paper rolls still needs to be manually adjusted afterward so that the paper feeder can accurately pick up the paper rolls. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] In existing technology, when a forklift places paper rolls onto the paper roll transport vehicle 4, the forklift driver cannot always place the paper rolls neatly on the vehicle. This is especially true for novice drivers, whose inaccurate placement of the paper rolls on the vehicle can lead to significant misalignment. Even if the vehicle stops accurately at the designated position, the paper roll may still be misaligned, requiring manual adjustment to ensure it can be accurately picked up by the paper feeding mechanism. Therefore, we propose the following solution to address these issues: like Figure 1 and Figure 2 As shown, the present invention provides an automatic paper roll transport device, including a conveying track 1 arranged along the paper roll conveying direction, and a paper roll transport vehicle 4 that slides along the length direction of the conveying track 1 on the conveying track 1. The upper surface of the paper roll transport vehicle 4 is provided with a placement groove 10, and a support seat 11 for placing paper rolls is slidably installed in the placement groove 10. The paper roll transport vehicle 4 is provided with a power mechanism for driving the support seat 11 to move relative to the paper roll transport vehicle 4. Driven by the power mechanism, the support seat 11 slides back and forth relative to the paper roll transport vehicle 4 along the length of the conveying track 1. A first pressure sensor 18 is installed on the wall of the placement slot 10, and the first pressure sensor 18 is located in the forward direction of the support 11. The first pressure sensor 18 monitors the position of the paper roll on the support 11 and shuts down the power mechanism. The output terminal of the first pressure sensor 18 is electrically connected to the input terminal of the controller. When the paper roll is placed on the support 11, the hollow central axis of the paper roll is higher than the paper roll transport vehicle 4 so that the paper roll can be picked up by the subsequent paper feeding machine. The first pressure sensor 18 is directly opposite the lower side of the paper roll.

[0020] When in use, the paper roll transport vehicle 4 is located to the left of the conveyor track 1 (within the left side). Figure 1 (For example), that is, in the designated area of ​​the paper loading station, the forklift driver places the paper roll on the support seat 11, and the right end of the paper roll can extend arbitrarily to the right side of the support seat 11 (this placement method greatly reduces the difficulty of accurately placing the paper roll, thus making it easier for the forklift driver to operate). Then, the paper roll transport vehicle 4 slides along the conveyor track 1 to transport the paper roll transport vehicle 4 to the paper loading area. During this process, the power mechanism is activated, and the power mechanism drives the support seat 11 to move to the right relative to the paper roll transport vehicle 4 within the placement slot 10 (towards...). Figure 2 (For example), when the right side of the paper roll comes into contact with the first pressure sensor 18, the first pressure sensor 18 triggers a signal, the controller receives the signal emitted by the first pressure sensor 18 and shuts off the power mechanism; In this way, each paper roll can be automatically positioned closer to the right side of the paper roll transport vehicle 4 when it is being transported by the paper roll transport vehicle 4. This ensures that the paper roll is in the designated position when the paper roll transport vehicle 4 is transported to the designated position, which reduces the difficulty of operation for the forklift driver and improves the accuracy of transporting the paper roll to the designated position.

[0021] In one embodiment, a lead screw 5 is installed on the conveying track 1, and a plurality of nut seats 7 are threaded on the lead screw 5, and the plurality of nut seats 7 are fixedly connected to the paper roll transport vehicle 4. A drive mechanism 2 is installed on the conveying track 1 to drive the lead screw 5 to rotate. The drive mechanism 2 drives the paper roll transport car 4 to slide back and forth along the length of the lead screw 5, and the paper roll is transported by the paper roll transport car 4.

[0022] When in use, the paper roll transport car 4 is located to the left of the lead screw 5 (within the left side). Figure 1 (For example), that is, the designated area of ​​the paper feeding station, the forklift places the protective paper roll on the paper roll transport vehicle 4, the drive mechanism 2 is turned on, the drive mechanism 2 drives the screw 5 to rotate, and the screw 5 drives the paper roll transport vehicle 4 to the paper feeding machine area on the right side of the screw 5 through the nut seat 7. This device is driven by a servo motor, eliminating the need for manual operation of the paper roll transport vehicle. This saves time and effort, and the smooth travel speed reduces the bumps experienced during paper roll transport, preventing the paper roll from rolling off the paper roll transport vehicle 4. Meanwhile, the paper roll transport vehicle 4 travels along the conveyor track 1, which has a fixed length. Therefore, it is easy to adjust the position of the paper roll transport vehicle 4 when it is transported to the corresponding paper feeder.

[0023] The existing paper roll transport vehicle 4 requires human observation to ensure it reaches the designated position before being pushed forward, so that the robotic arm of the paper feeding machine can accurately pick up the cover paper roll. This process has a large margin of error and often requires at least two workers to work together, resulting in excessive waste of human resources. To address these issues, we propose the following solution: Reference Figure 1 As shown, a photoelectric sensor 6 and a controller are installed on the conveying track 1. The output end of the photoelectric sensor 6 is electrically connected to the input end of the controller, that is, the photoelectric sensor 6 transmits the monitoring signal to the controller in real time, and the controller processes the signal and then reacts. The photoelectric sensor 6 is used to monitor whether the paper roll transport vehicle 4 has accurately arrived at the preset position, and the controller is used to control the opening or closing of the drive mechanism 2.

[0024] In use, the photoelectric sensor 6 is installed in the designated area of ​​the paper feeder. When the paper roll transport vehicle 4 moves to the designated position (i.e. above the photoelectric sensor 6), the photoelectric sensor 6 triggers a signal and transmits the signal to the controller. The controller immediately shuts down the drive mechanism 2, so that the paper roll transport vehicle 4 can be accurately parked in the designated position without the need for manual observation, making it convenient to use.

[0025] After each transport, the power mechanism needs to be activated to reset the support 11 so that the paper roll can be placed and transported again. However, the support 11 is located inside the placement slot 10, making it difficult to observe its position. Therefore, we propose the following solution to address the above problem: Reference Figure 2 As shown, a second pressure sensor 19 is installed on the wall of the placement slot 10, which is directly opposite to the side wall of the support 11. The second pressure sensor 19 is located in the return direction of the support 11. The position of the support 11 and the power mechanism are monitored by the second pressure sensor 19. The output terminal of the second pressure sensor 19 is electrically connected to the input terminal of the controller; The length of the support 11 is smaller than the length of the paper roll.

[0026] When the paper roll transport vehicle 4 returns to the designated area for loading paper, the power mechanism is activated in reverse, driving the support seat 11 to move to the left relative to the paper roll transport vehicle 4 (as shown in the image). Figure 2 (For illustration) When the left side of the support 11 comes into contact with the second pressure sensor 19, the controller shuts off the power mechanism; Before each paper roll is placed on the support 11, the support 11 is located on the left side of the placement slot 10. Since the length of the support 11 is smaller than the length of the paper roll, as long as the paper roll is placed on the support 11, the right side of the paper roll will extend out of the support 11, which can further reduce the difficulty for the forklift driver to place the paper roll.

[0027] Reference Figure 2 and Figure 4As shown, in one embodiment, the power mechanism includes a first toothed plate 8 fixedly installed on the conveying track 1, and the first toothed plate 8 is arranged along the length direction of the conveying track 1. A gear 9 is rotatably installed on the paper roll transport vehicle 4, and the gear 9 meshes with the first toothed plate 8. A second toothed plate 17 is installed on the lower side of the support 11 via a telescopic mechanism. Under the action of the telescopic mechanism, the second toothed plate 17 engages or disengages with the gear 9.

[0028] When in use, the power mechanism is activated (by driving the second toothed plate 17 to mesh with the gear through the telescopic mechanism). When the paper roll transport vehicle 4 moves, the first gear 8 drives the gear 9 to rotate, and the gear 9 drives the support plate 11 to move relative to the paper roll transport vehicle 4 through the second gear 17.

[0029] Reference Figure 2 and Figure 3 As shown, in one embodiment, the lower end face of the support 11 is provided with a mounting groove 12. Under the action of the telescopic mechanism, the second toothed plate 17 is retracted into the mounting groove 12 or extends out of the mounting groove 12. The telescopic mechanism includes a hydraulic rod 13 installed in the mounting groove 12, and the telescopic end of the hydraulic rod 13 is fixedly connected to the second toothed plate 17 through a floating joint.

[0030] Preferably, the upper surface of the support 11 is a concave arc-shaped surface to prevent the paper roll from rolling arbitrarily on the upper surface of the support 11, and multiple adjustable resistance elements are provided on the arc-shaped surface.

[0031] Preferably, refer to Figure 3 As shown, the adjustable resistance component includes a strip-shaped first airbag 16, and a groove 15 for accommodating the first airbag 16 is provided on the arc-shaped surface, and the groove 15 is arranged along the length direction of the conveying track 1. A second airbag 14 is provided between the wall of the mounting groove 12 and the second toothed plate 17, and each first airbag 16 and the second airbag 14 are connected by a connecting pipe. Under the action of the hydraulic rod 13, the second airbag 14 and the first airbag 16 expand or contract. Hydraulic oil is filled in the second airbag 14, each of the first airbags 16, and the connecting pipe. By filling the first airbag 16, the second airbag 14, and the connecting pipe with hydraulic oil, the transmission efficiency between the first airbag 14 and the second airbag 16 and the deformation of the first airbag 16 are improved.

[0032] During use, the power mechanism drives the support 11 to move toward the first pressure sensor 18. When the paper roll comes into contact with the first pressure sensor 18, the support 11 continues to move a distance toward the first pressure sensor 18 (a delay module is set at the output of the first pressure sensor 18, that is, the first pressure sensor 18 is triggered by pressure for a certain period of time before sending a signal to the controller). The support 11 slides relative to the paper roll, so that the paper roll is placed in the middle of the support 11, thereby avoiding the paper roll from extending too far out of the support 11 and reducing the stability of the paper roll. At this time, the first airbag 16 is stored in the sink 15. The first airbag 16 does not contact the paper roll, and the paper roll and the support 11 can slide quickly relative to each other. When the support 11 stops moving, that is, when the paper roll is located in the middle of the support 11, the hydraulic rod drives the second toothed plate 17 to be stored in the mounting groove 12. The second toothed plate 17 compresses the second airbag 14, and the multiple first airbags 16 expand and extend out of the sink 15 to contact the peripheral wall of the paper roll. At this time, the first airbags 16 increase the friction between the paper roll and the support 11, which improves the stability of the paper roll and avoids damage to the surface of the paper roll.

[0033] Preferably, a channel is provided between the bottom wall of the placement groove 10 and the lower end face of the paper roll transport vehicle 4, and the gear 9 is rotatably installed in the channel via a rotating shaft, with the teeth on the peripheral wall of the gear 9 extending to the bottom of the paper roll transport vehicle 4 and into the placement groove 10.

[0034] Preferably, a guide rod 20 is installed on the lower end face of the support 11, a guide groove is provided on the bottom wall of the placement groove 10, and the guide rod 20 is slidably connected to the guide groove. A ball bearing is rotatably installed on the lower end face of the guide rod 20 to reduce the friction between the guide rod 20 and the guide groove. The guide rod 20 and the guide groove play a guiding role for the support 11.
