[0002] In the paper production process, after the paper rolls come off the rewinder, they need to undergo multiple processes such as weighing, coding, slitting, packaging, labeling, and palletizing. Therefore, a conveying device is required to transport the paper rolls to different workstations. However, due to limitations in production line layout and process standardization, the paper rolls usually need to be turned during the conveying process. However, existing paper roll turning devices occupy a large area and are costly. Utility Model Content

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0025] It should also be noted that the division of multiple embodiments in this utility model is only for the convenience of description and should not constitute a special limitation. Features in various embodiments can be combined and referenced in each other without contradiction. In the drawings, X indicates the first direction, Y indicates the second direction, and Z indicates the vertical direction.

[0026] In existing technologies, to enable paper rolls to enter different conveyor lines and complete different processes, a paper roll turning device is generally used to turn the paper roll so that it can enter different conveyor lines. The paper roll is transported from one conveyor line to the paper roll turning device, which then rotates the paper roll to a designated position. Finally, the paper roll turning device drives the paper roll to move to another conveyor line. Because the existing paper roll turning device not only needs to rotate the paper roll but also requires an additional mechanism to drive the paper roll to the conveyor line, the existing paper roll turning device has a large footprint and high cost.

[0027] Based on this, see Figure 1 and Figure 2 This utility model provides a paper roll conveying device 1, including a first paper roll conveying device 20, a mounting frame 11, and a rotary lifting mechanism 12. The top of the first paper roll conveying device 20 is provided with a first conveying surface 22, and the paper roll can be placed on the first conveying surface 22 so that the first paper roll conveying device 20 conveys the paper roll.

[0028] The top of the mounting frame 11 is recessed to form a clearance space 111. Below the clearance space 111, there is an installation space 112 that penetrates the mounting frame 11. The first paper roll conveying device 20 is partially disposed in the installation space 112.

[0029] The rotary lifting mechanism 12 includes a support component 121, which is located in the clearance space 111 and can be raised, lowered, and rotated within the clearance space 111. Thus, when the support component 121 supports the paper roll, it can drive the paper roll to be raised, lowered, and rotated. Therefore, allowing the support component 121 to be raised, lowered, and rotated within the clearance space 111 avoids interference between the support component 121 and the first paper roll conveying device 20, which helps improve the independence between the rotary lifting mechanism 12 and the paper roll conveying device, thereby contributing to a reduction in the size of the paper roll reversing device 10 and minimizing interference.

[0030] The carrier assembly 121 has a raised state and a lowered state. In the raised state, the carrier assembly 121 is higher than the first conveying surface 22. When the carrier assembly 121 is raised to its highest point in the clearance space 111, it is higher than the first paper roll conveying devices 20 located on both sides of the clearance space 111. This allows the carrier assembly 121 to avoid interference from obstacles such as paper roll conveying devices when it drives the paper roll to rotate and change direction. In the lowered state, the carrier assembly 121 is lower than or level with the first conveying surface 22. This prevents the carrier assembly 121 from blocking the conveying of the paper roll, allowing the paper roll to be smoothly conveyed by the first paper roll conveying device 20 to the top of the carrier assembly 121, where it can then be lifted.

[0031] It is understandable that paper rolls are generally cylindrical and are usually transported along the axial direction of the paper roll. In other words, when the paper roll is transported, the transport direction is the same as the axial direction of the paper roll.

[0032] A specific embodiment of this utility model is described below. A first paper roll conveying device 20 is arranged, for example, along a first direction, thereby conveying the paper roll along the first direction. On one side of the paper roll reversing device 10 along a second direction, a second paper roll conveying device 30 is also connected, for example, along the second direction. The second paper roll conveying device 30 can convey the paper roll along the second direction. The second paper roll conveying device 30 has a second conveying surface, which is coplanar with the first conveying surface 22. The first direction and the second direction are, for example, perpendicular. The paper roll is conveyed by the first paper roll conveying device 20 along the first direction. The carrier component 121 switches to a lowering state, descending below the first conveying surface 22. The first paper roll conveying device 20 conveys the paper roll above the carrier component 121. The carrier component 121 rises, lifting the paper roll and then rotating it to change direction. When it rotates to a designated position, for example, when the paper roll axis is in the same direction as the second direction, the carrier component 121 descends to be flush with the second conveying surface. Part of the paper roll is placed on the second conveying surface, while the carrier component 121 continues to carry the paper. The second paper roll conveying device 30 then moves the paper roll out of the carrier component and onto the second conveying surface. The second paper roll conveying device 30 further conveys the paper roll along the second direction. Specifically, for example, when the first paper roll conveying device 20 conveys the paper roll above the carrier component 121, the center of gravity of the paper roll corresponds to the carrier component 121. In this way, the carrier component 121 can carry the paper roll more stably, and the paper roll is more stable during rising, falling, and rotating.

[0033] The paper roll reversing device 10 provided by this utility model, by setting an installation space 112 and partially placing the first paper roll conveying device 20 in the installation space 112, allows the paper roll reversing device 10 to be directly installed on the first paper roll conveying device 20, effectively saving the floor space occupied by the paper roll reversing device 10, thereby reducing the floor space occupied by the paper roll conveying equipment 1 and effectively reducing costs; furthermore, by setting an obstacle space 111, the first paper roll conveying device 20 is placed below the obstacle space 111, thereby avoiding interference between the supporting component 121 and the first paper roll conveying device 20, and preventing the lifting and rotating of the supporting component 121. The operation of the first paper roll conveying device 20 is disrupted, while the independence of the rotary lifting mechanism 12 is improved, making it easier to set up. This helps to reduce the volume of the paper roll reversing device 10, thereby further reducing its size and cost. Meanwhile, the paper roll reversing device 10 itself only rotates and lifts the paper roll. The transport of the paper roll along the first direction, second direction, etc., is carried out by the first paper roll conveying device 20, the second paper roll conveying device 30, etc. Therefore, the paper roll reversing device 10 does not need to have a structure for conveying the paper roll, effectively reducing its size and further reducing costs.

[0034] In some specific embodiments, the first paper roll conveying device 20 includes, for example, two opposing parts respectively disposed on the mounting frame 11, which can reduce the occupation of the installation space 112 and facilitate the installation of the rotating lifting mechanism 12.

[0035] In some embodiments, see Figure 2The rotary lifting mechanism 12 includes a support frame 122, a rotating component 123, and a lifting component 124. The rotating component 123 is connected to the bearing component 121, which is located on top of the support frame 122. The lifting component 124 is fixed to the bottom of the mounting frame 11 and drives the support frame 122 to rise and fall, thereby raising and lowering the bearing component 121 on top of the support frame 122. The lifting component 124 is located in the mounting space 112. The rotating component 123 is mounted on the mounting frame 11 and drives the bearing component 121 to rotate. The first paper roll conveying device 20 is recessed at the corresponding location of the clearance space 111, and the bearing component 121 is located in the recess. In other words, the first paper roll conveying device 20 passes through the mounting space 112, thus eliminating the need for two separate parts, simplifying the structure, and making it more compact to further reduce its size. In this way, the lifting and rotation of the supporting component 121 can be realized, which in turn can drive the lifting and rotation of the paper roll. Furthermore, the lifting component 124 is fixed to the bottom of the mounting frame 11, which can reduce the installation space 112 occupied, thereby facilitating the setting of the first paper roll conveying device 20 and helping to reduce the probability of mutual interference during operation. At the same time, the lifting component 124 is located in the installation space 112, which can prevent the side of the mounting frame 11 away from the clearance space 111 from protruding, thereby facilitating the installation of the mounting frame 11.

[0036] Specifically, see Figure 2 and Figure 3 The lifting assembly 124 includes, for example, a lifting drive 1241 and a lifting connector 1242. The lifting drive 1241 is fixed to the bottom of the mounting frame 11, and the lifting connector 1242 connects the lifting drive 1241 to the support frame 122. Thus, the lifting drive 1241 drives the support frame 122 to rise and fall through the lifting connector 1242. The lifting drive 1241 is, for example, a cylinder. Cylinders have a simple structure, are easy to install and maintain, have low cost, and offer good stability and high safety, making them suitable for industrial environments. The lifting connector 1242 is, for example, a connecting rod. The middle of the connecting rod is connected to the lifting drive 1241, and the two ends of the connecting rod are respectively connected to the two sides of the support frame 122 perpendicular to the first direction. This structure is simple and reduces the installation space 112 occupied in the vertical direction, thereby leaving more space for the first paper roll conveying device 20 and further reducing interference between components.

[0037] For some specific embodiments, see Figure 2 and Figure 3The rotating assembly 123 includes a first gear 1231, a second gear 1232, a rotating connector 1233, and a rotating drive 1234. The first gear 1231 is rotatably mounted on the top of the support frame 122 and connected to the bearing assembly 121. The second gear 1232 is mounted on the support frame 122, and the first gear 1231 meshes with the second gear 1232. The rotating connector 1233 drives the rotating drive 1234 and the second gear 1232. The number of teeth of the second gear 1232 is less than the number of teeth of the first gear 1231. The rotating drive 1234 drives the rotating connector 1233 to rotate, thereby driving the second gear 1232 to rotate. In turn, the second gear 1232 drives the first gear 1231 to rotate through meshing with the first gear 1231, thereby causing the bearing assembly 121 to rotate. In this way, the transmission is achieved through gear meshing, which makes the operation smooth and helps the paper roll remain stable during rotation, reducing the chance of the paper roll coming off the support component 121. Furthermore, the number of teeth of the second gear 1232 is less than the number of teeth of the first gear 1231, which can achieve speed reduction transmission and increase torque, making it easier to drive the paper roll to rotate.

[0038] Specifically, see Figure 3 and Figure 5 The rotating assembly 123 also includes a slewing bearing 1235, through which the first gear 1231 is rotatably mounted on the top of the support frame 122. The slewing bearing 1235 has a strong load-bearing capacity, can withstand a large overturning moment, is easy to install, and has good stability.

[0039] Specifically, see Figure 3 and Figure 5 The rotary connector 1233 includes two couplings and a rotary connecting rod 1238. Two couplings 1239 are respectively located at both ends of the rotary connecting rod 1238. One coupling 1239 is connected to the second gear 1232, and the other coupling 1239 is connected to the first gear 1231. The rotary drive 1234 drives one coupling 1239 to rotate, thereby causing the rotary connecting rod 1238 to rotate, which in turn drives the other coupling 1239 to rotate, thereby causing the second gear 1232 to rotate. Thus, using couplings 1239 for transmission is safe, reliable, and has high strength. The structure is simple, easy to assemble and disassemble, and provides some buffering to protect the rotary drive 1234. Specifically, the coupling 1239 is, for example, a universal joint coupling, that is, the coupling 1239 is also provided with a universal joint. The coupling 1239 is connected to the rotating connecting rod 1238 through the universal joint, so that the rotating connecting rod 1238 can be set at an angle, thereby facilitating the installation of the coupling 1239, the rotating drive component 1234 and the rotating connecting rod 1238 on the side of the mounting bracket 11.

[0040] Specifically, the rotary drive components 1234 are, for example, electric motors, which operate smoothly, are easy to maintain, and produce minimal pollution during operation. These motors can be, for example, asynchronous motors, which are low-cost and easy to maintain; or they can be servo motors, which offer high precision and are easy to control.

[0041] Further, see Figure 3 and Figure 5 The slewing bearing 1235 includes an inner ring 1236 and an outer ring 1237, which are rotatably connected. The outer ring 1237 is, for example, fixed to the top of the support frame 122. A first gear 1231 is disposed on the inner ring 1236, meaning that the first gear 1231 and a second gear 1232 mesh on the inner side of the slewing bearing 1235. Thus, the second gear 1232 can be disposed on the inner side of the inner ring 1236, resulting in a compact structure.

[0042] In some embodiments, the inner ring 1236 is fixed to the top of the support frame 122, for example, and the first gear 1231 is disposed on the outer ring 1237, that is, the first gear 1231 and the second gear 1232 mesh on the outside of the outer ring 1237. This facilitates increasing the number of gears in the first gear 1231, which helps to increase the gear ratio, improve the output torque of the first gear 1231, and make it easier to drive the paper roll to rotate; it also facilitates increasing the size of the bearing assembly 121, thereby helping to increase the anti-overturning lever arm and reduce the probability of the paper roll overturning; at the same time, the second gear 1232 can be disposed on the outside of the outer ring 1237, which avoids occupying the installation space 112, and makes it easier to install the second gear 1232, reducing the probability of the second gear 1232 interfering with other components.

[0043] For some specific embodiments, see Figure 2 The second gear 1232, the rotary connector 1233, and the rotary drive 1234 are all, for example, arranged on one side of the mounting frame 11 perpendicular to the first direction. This reduces the space occupied by the mounting space 112, facilitates the installation of the first paper roll conveying mechanism, avoids interference with the lifting assembly 124's raising and lowering of the support frame 122, helps reduce the size of the paper roll reversing device 10, and also reduces the structural complexity of the paper roll reversing device 10, making disassembly and maintenance easier.

[0044] In some embodiments, see Figure 3 and Figure 5The supporting component 121 includes a tray 1211. An arc-shaped supporting surface 1212 is formed on the side of the tray 1211 away from the clearance space 111 to increase the contact area with the paper roll, reduce the contact pressure between the paper roll and the tray 1211, and protect the paper roll and the tray 1211. At the same time, it can limit the paper roll and constrain the paper roll to roll around the circumference. Furthermore, the arc-shaped supporting surface 1212 helps to automatically center the paper roll, making the paper roll more stable and facilitating alignment with the first paper roll conveying device 20, thereby facilitating the paper roll conveying.

[0045] In some embodiments, see Figures 2 to 5 The paper roll reversing device 10 includes two guide components 125, which are respectively located on both sides of the mounting frame 11 perpendicular to the first direction to avoid occupying the installation space 112, thereby facilitating the installation of the first paper roll conveying device 20. The guide components 125 are connected to the support frame 122, so that the two guide components 125 can guide from both sides of the mounting frame 11, which can improve the stability of the support frame 122 when it is lifted or lowered by the lifting component, thereby improving the stability of the paper roll during ascent and descent.

[0046] Specifically, see Figures 2 to 5 The guide assembly 125 includes two sets of guide limiting members 1252 and two guide connecting members 1251. The two sets of guide limiting members 1252 are spaced apart along the first direction, and the two guide connecting members 1251 are respectively connected to the support frame 122 and respectively limited by the guide limiting members 1252. Thus, on both sides of the mounting frame 11 perpendicular to the first direction, there is a pair of cooperating guide limiting members 1252 and two guide connecting members 1251, which can further improve the stability of the paper roll when rising and falling.

[0047] Further, see Figures 2 to 5The guide limiting member 1252 includes a claw 1253 and a roller 1254. Each claw 1253 is provided with two rollers 1254. For example, there are two claws 1253. The two claws 1253 are arranged at intervals in the vertical direction. The claws 1253 of the two sets of guide limiting members 1252 are arranged correspondingly to each other. The claws 1253 and the mounting frame 11 surround to form a limiting space 1255. One roller 1254 is located in the limiting space 1255 of one claw 1253 on the side away from the corresponding other claw 1253. The other roller 1254 is located in the limiting space 1255 on the side away from the mounting frame 11. The guide connector 1251 is at least partially located in the limiting space 1255. When the support frame 122 rises or falls, the two rollers 1254 within each claw 1253 respectively limit and abut against the guide connector 1251 in the first and second directions, thereby restricting the movement of the guide connector 1251 in the first and second directions and thus guiding the support frame 122. In this way, the claws 1253 and rollers 1254 can limit movement in the first and second directions, further increasing guiding stability.

[0048] In some embodiments, the paper roll conveying device 1 further includes a second paper roll conveying device 30, which is arranged along a second direction and connected to the paper roll reversing device 10; a first paper roll conveying device 20 is arranged along a first direction, which is perpendicular to the second direction. The first paper roll conveying device 20 can convey the paper roll to the paper roll reversing device 10, whereby the reversing device 10 lifts and reverses the paper roll to the second direction, and the second paper roll conveying device 30 moves the entire paper roll to the second paper roll conveying device 30 for conveying. Alternatively, the paper roll can be conveyed from the second paper roll conveying device 30 to the paper roll reversing device 10, whereby the reversing device 10 reverses the direction, and then the first paper roll conveying device 20 conveys the paper roll along the first direction. The first direction is perpendicular to the second direction to facilitate the arrangement of the first paper roll conveying device 20 and the second paper roll conveying device 30 as much as possible and avoid mutual interference.

[0049] Specifically, see Figure 1 The paper roll conveying device 1 also includes a third paper roll conveying device 40 connected to the paper roll reversing device 10. The third paper roll conveying device 40 is arranged along the second direction, and the second paper roll conveying device 30 and the third paper roll conveying device 40 are located on opposite sides of the first paper roll conveying device 20 along the first direction. In this way, the paper roll can be conveyed in more directions.

[0050] In some embodiments, see Figure 1 and Figure 2The first paper roll conveying device 20 includes a first plate chain conveyor 21, which includes a first plate chain 211. The second paper roll conveying device 30 includes a second plate chain conveyor 31, which includes a second plate chain 311. The carrying component 121 includes a pallet 1211, which is annular. The diameter of the outer circumference of the pallet 1211 is larger than the width of the first plate chain 211 and the second plate chain 311. The plate chain conveyor has high load-bearing capacity, is not easily deformed, and provides stable conveying. Furthermore, a concave surface can be formed on the plate chain to conform to the paper roll, preventing the paper roll from rolling. The diameter of the outer circumference of the pallet 1211 is larger than the width of the first plate chain conveyor 21 and the second plate chain conveyor 31, which helps to increase the distance between the end of the second plate chain conveyor 31 connected to the paper roll reversing device 10 and the first plate chain conveyor 21, thereby avoiding interference and preventing mutual influence during paper roll reversing conveying.

[0051] In some embodiments, see Figure 4 The first plate chain conveyor 21 includes a first guide rail 212, which is located on opposite sides of the mounting frame 11. A first plate chain 211 is disposed within the first guide rail 212. A clearance guide rail 113 is provided in the mounting space 112, and is located below the clearance space 111. The clearance guide rail 113 is connected to the first guide rails 212 on opposite sides of the mounting frame 11, and at least a portion of the first plate chain 211 is disposed within the clearance guide rail 113. It is understood that the first guide rails 212 located on both sides of the paper roll reversing device 10 along the first direction are connected to the clearance guide rails 113.
