Description

Technical Field

[0001] This utility model relates to the technical field of corrugated paper production equipment, and in particular to a device for transporting and replacing raw paper rolls. Background Technology

[0002] In the corrugated paper manufacturing industry, base paper refers to the basic paper type used in producing corrugated board and is the core raw material for corrugated board processing. It is also commonly referred to as corrugated base paper or linerboard base paper. In actual production, base paper rolls need to be placed at the base paper loading station on the corrugated board production line, and after the base paper is used up, a new roll needs to be replaced at the base paper loading station. Previously, production operations relied on vehicles and various auxiliary equipment working together, resulting in a cumbersome process.

[0003] To address the aforementioned issues, Chinese patent document CN202020803328.8 discloses an automatic paper roll conveying device, which achieves automated paper roll conveying through a gantry crane and a multi-axis driven robotic arm. However, in the disclosed automatic paper roll conveying device, the movement of the crossbeam along the X-axis direction relies on two X-axis drive devices. This not only requires extremely high coordination capabilities from the two X-axis drive devices, but also necessitates additional drive devices compared to a single X-axis drive device, leading to increased equipment investment and maintenance costs. Furthermore, the disclosed automatic paper roll conveying device can only achieve the basic transportation function of the paper roll; it cannot achieve automatic paper loading and unloading operations at the paper rack loading station. Utility Model Content

[0004] The purpose of this utility model is to provide a paper roll transport and replacement device, which aims to solve the problems of high equipment investment and maintenance costs and the inability to realize automatic paper roll loading and unloading operations in existing automatic paper roll conveying devices.

[0005] To solve the above-mentioned technical problems, this utility model provides a paper roll transport and replacement device, including two opposing crossbeams, a longitudinal beam disposed between the two crossbeams, and two paper insertion assemblies movably disposed on the longitudinal beam; the two ends of the longitudinal beam are fixedly connected to a first movable frame; the two first movable frames are respectively movably connected to the two crossbeams, and one of the first movable frames is provided with an X-axis drive mechanism; the X-axis drive mechanism includes a first cylinder and a first telescopic rod; the first cylinder is fixed on the first movable frame; the first telescopic rod is movably connected to the first cylinder, and one end of the first telescopic rod is fixed to the crossbeam; a transmission rod is provided beside the longitudinal beam; the transmission rod is rotatably connected to the two first movable frames, and gears are fixedly connected to both ends of the transmission rod; racks are provided on both crossbeams along the length direction of the crossbeam; the gears mesh with the racks.

[0006] Optionally, the first movable frame is connected to rollers; both crossbeams are provided with first guide rails along the length of the crossbeams, and the rollers are rotatably mounted on the first guide rails.

[0007] Optionally, a first proximity switch is provided on the crossbeam at both ends of the first guide rail.

[0008] Optionally, the longitudinal beam is provided with two Y-axis drive mechanisms; the Y-axis drive mechanism includes a second cylinder and a second telescopic rod; the second cylinder is fixed on the longitudinal beam; the second telescopic rod is movably connected to the second cylinder, and one end of the second telescopic rod is fixed to the top of the paper insertion assembly.

[0009] Optionally, a second proximity switch is provided on the side of the first movable shelf facing the paper insertion assembly.

[0010] Optionally, the paper insertion assembly includes a second movable frame movably connected to the longitudinal beam, a vertically arranged hanger movably connected to the second movable frame, a paper insertion mechanism fixed to the lower end of the hanger, and a Z-axis drive mechanism disposed on the second movable frame; the Z-axis drive mechanism includes a third cylinder and a third telescopic rod; the third cylinder is vertically fixed to the second movable frame; the third telescopic rod is movably connected to the third cylinder, and the lower end of the third telescopic rod is fixed to the hanger.

[0013] Optionally, a guide portion is provided on the longitudinal beam along the length direction of the longitudinal beam; the second movable frame is provided with a U-shaped groove that cooperates with the guide portion.

[0014] Beneficial effects:

[0015] This invention provides a paper roll transport and replacement device. It utilizes a first movable frame fixed to both ends of a longitudinal beam and movably connected to a crossbeam. An X-axis drive mechanism, consisting of a first cylinder and a first telescopic rod, is mounted on one of the first movable frames. The telescopic movement of the first telescopic rod, whose outer end is fixed to the crossbeam, moves the first cylinder relative to the first telescopic rod, thereby driving the first movable frame and the longitudinal beam connected to it to move along the length of the crossbeam (i.e., the X-axis direction), thus transporting the paper roll. Furthermore, by installing a transmission rod beside the longitudinal beam, connecting the two first movable frames, and employing a gear and rack meshing structure, the first movable frames at both ends of the longitudinal beam can move synchronously along the crossbeam, ensuring the smoothness and consistency of the longitudinal beam's X-axis movement and preventing longitudinal beam misalignment caused by unilateral drive. Compared to existing automatic paper roll conveying devices, this invention ensures reliable operation without requiring two X-axis drive mechanisms, reducing the demands on the coordination capabilities of the drive devices and lowering both investment and maintenance costs.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0040] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0041] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0042] Please see Figures 1 to 12 This utility model provides a paper roll 14 transport and replacement device, including two crossbeams 1 arranged opposite each other, a longitudinal beam 2 arranged between the two crossbeams 1, and two paper insertion components 3 movably arranged on the longitudinal beam 2.

[0043] Specifically, the two crossbeams 1 are components of the gantry frame; and the two ends of the longitudinal beam 2 are fixedly connected to the first movable frame 4. The two first movable frames 4 are respectively movably connected to the two crossbeams 1, and one of the first movable frames 4 is equipped with an X-axis drive mechanism 5. The X-axis drive mechanism 5 includes a first cylinder 51 and a first telescopic rod 52, wherein the first cylinder 51 is fixed to the first movable frame 4; the first telescopic rod 52 is movably connected to the first cylinder 51, and one end of the first telescopic rod 52 is fixed to the crossbeam 1.

[0044] Since one end of the first telescopic rod 52 is fixed to the crossbeam 1, when the X-axis drive mechanism 5 is working, the telescopic movement of the first telescopic rod 52 allows the first cylinder 51 fixed to the first movable frame 4 to move relative to the first telescopic rod 52. This, in turn, drives the first movable frame 4 and the longitudinal beam 2 connected to the first movable frame 4 to move along the length direction of the crossbeam 1 (i.e., the X-axis direction), thereby realizing the transportation of the raw paper roll 14. For example, it transports a new raw paper roll 14 to the raw paper loading station 15 to replace the roll that is about to run out of raw paper. Compared with the existing automatic conveying device for raw paper roll 14, this utility model does not require two X-axis drive mechanisms 5, which not only reduces the requirements for the coordination capability of the drive device, but also reduces the investment and maintenance costs of the equipment.

[0045] For example, the first cylinder 51 can be a hydraulic cylinder. Compared to a servo motor, a hydraulic cylinder has a larger output torque, stronger load-bearing capacity, and a simpler structure with lower maintenance costs.

[0046] like Figure 1 , Figure 3 , Figure 4 , Figure 10 as well as Figure 11 As shown, in an optional embodiment, a transmission rod 6 is provided beside the longitudinal beam 2. The axial direction of the transmission rod 6 is parallel to the length direction of the longitudinal beam 2, and the transmission rod 6 is rotatably connected to the two first movable frames 4. Gears 7 are fixedly connected to both ends of the transmission rod 6; racks 8 are provided on both crossbeams 1 along the length direction of the crossbeam 1; the racks 8 can be set at the bottom of the crossbeam 1. The gears 7 mesh with the racks 8.

[0047] The transmission rod 6 connects the two first movable frames 4, and the meshing structure of the gear 7 and rack 8 allows the first movable frames 4 at both ends of the longitudinal beam 2 to move synchronously along the crossbeam 1, thereby ensuring the smoothness and consistency of the longitudinal beam 2's movement in the X-axis direction and avoiding the situation where the longitudinal beam 2 deviates due to unilateral drive.

[0048] like Figure 3 and Figure 4 As shown, in an optional embodiment, the first movable frame 4 is connected to at least two rollers 9; both of the two crossbeams 1 are provided with first guide rails 10 along the length direction of the crossbeams 1, and the rollers 9 are rolled on the first guide rails 10, which can provide stable support for the first movable frame 4 and the longitudinal beam 2, distribute the load pressure, and at the same time, the rolling friction can reduce the resistance of the longitudinal beam 2 moving in the X-axis direction, so that the longitudinal beam 2 carrying the paper insertion assembly 3 moves more smoothly, thereby ensuring that the transportation and replacement of the raw paper roll 14 are carried out efficiently.

[0049] like Figure 5As shown, in an optional embodiment, a first proximity switch 11 is provided at both ends of the first guide rail 10 on the crossbeam 1. The first proximity switch 11 is used to detect the first movable frame 4, and the first proximity switch 11 is electrically connected to a controller. The X-axis drive mechanism 5 is electrically connected to the controller. If the first movable frame 4 is detected by the first proximity switch 11 during movement, the first proximity switch 11 will transmit a detection signal to the controller. At this time, the controller will control the X-axis drive mechanism 5 to stop working, thereby preventing the roller 9 from derailing through the detection of the first movable frame 4 by the first proximity switch 11, ensuring the safety of equipment operation.

[0050] like Figures 5 to 9 As shown, in an optional embodiment, the longitudinal beam 2 is provided with two Y-axis drive mechanisms 12; each Y-axis drive mechanism 12 includes a second cylinder 121 and a second telescopic rod 122; the second cylinder 121 is fixed on the longitudinal beam 2; the second telescopic rod 122 is movably connected to the second cylinder 121, and one end of the second telescopic rod 122 is fixed to the top of the paper insertion assembly 3. Since the second cylinder 121 is fixed on the longitudinal beam 2, the paper insertion assembly 3 can be driven to reciprocate along the length direction (i.e., the Y-axis direction) of the longitudinal beam 2 by means of the telescopic movement of the second telescopic rod 122, so that the two paper insertion assemblies 3 can be unfolded and retracted under the drive of the two Y-axis drive mechanisms 12, thereby clamping and releasing paper rolls 14 of different lengths, realizing the handling and replacement operation of the paper rolls 14.

[0051] For example, the second cylinder 121 may be a hydraulic cylinder.

[0052] like Figure 3 As shown, in an optional embodiment, each of the two first movable frames 4 is provided with a second proximity switch 13 on the side facing the paper insertion assembly 3. The second proximity switch 13 is used to detect the paper insertion assembly 3, and the second proximity switch 13 is electrically connected to the controller. The Y-axis drive mechanism 12 is also electrically connected to the controller. If the paper insertion assembly 3 is detected by the second proximity switch 13 during movement, the second proximity switch 13 will transmit a detection signal to the controller. At this time, the controller will control the Y-axis drive mechanism 12 to stop working, thereby preventing the paper insertion assembly 3 from colliding with the first movable frame 4.

[0053] like Figures 5 to 7As shown, in an optional embodiment, the paper insertion assembly 3 includes a second movable frame 301 movably connected to the longitudinal beam 2, a vertically arranged hanger 302 movably connected to the second movable frame 301, a paper insertion mechanism 303 fixed to the lower end of the hanger 302, and a Z-axis drive mechanism 304 disposed on the second movable frame 301. The Z-axis drive mechanism 304 includes a third cylinder 3041 and a third telescopic rod 3042; the third cylinder 3041 is vertically fixed to the second movable frame 301; the third telescopic rod 3042 is movably connected to the third cylinder 3041, and the lower end of the third telescopic rod 3042 is fixed to the hanger 302.

[0054] Since the upper part of the third cylinder 3041 is fixed to the second movable frame 301, the extension and retraction of the third telescopic rod 3042 can drive the hanger 302 and the paper insertion mechanism 303 to rise and fall vertically, allowing the paper insertion mechanism 303 to flexibly adjust its height to adapt to the paper roll 14 under different usage conditions. For example, when the paper is about to run out, the old paper roll 14 will be lower than the new paper roll 14 to be replaced (e.g., ...). Figure 10 As shown in the figure, when the height of the paper insertion mechanism 303 can be flexibly adjusted, it can ensure that the paper roll 14 under different usage conditions can be picked up and placed.

[0055] For example, the third cylinder 3041 may be a hydraulic cylinder.

[0056] like Figure 6 As shown, in an optional embodiment, the paper insertion mechanism 303 includes a mounting frame 3032, a conical insert 3033 rotatably mounted on the mounting frame 3032, and a magnetic powder brake 3031 mounted on the mounting frame 3032; the conical insert 3033 is kinetically connected to the magnetic powder brake 3031. The magnetic powder brake 3031 can adjust the output damping force according to the operation requirements, providing appropriate resistance control for the rotation of the conical insert 3033. When the raw paper is automatically wound, the magnetic powder brake 3031 applies moderate damping, allowing the conical insert 3033 to rotate smoothly with the traction of the raw paper, preventing the raw paper from becoming loose or shifting due to excessive rotation; while in the raw paper rewinding operation, the damping magnitude can be flexibly adjusted to keep the rewinding tension of the raw paper roll 14 uniform, preventing the raw paper from being torn due to excessive tension or causing irregular rewinding due to insufficient tension.

[0057] like Figure 6As shown, in an optional embodiment, the hanger 302 is provided with guide grooves 3021 on both sides in the vertical direction; the second movable frame 301 is provided with a second guide rail 305 that cooperates with the guide grooves 3021. In this embodiment, the guiding structure of the guide grooves 3021 and the second guide rail 305 can limit the movement trajectory of the hanger 302 in the vertical direction. When the Z-axis drive mechanism 304 drives the hanger 302 to rise and fall, it can prevent the hanger 302 from deviating and shaking, thereby ensuring that the paper insertion mechanism 303 is aligned with the center hole of the paper roll 14.

[0058] like Figure 6 As shown, in an optional embodiment, a guide portion 201 is provided on the longitudinal beam 2 along its length; the second movable frame 301 is provided with a U-shaped groove 3011 that cooperates with the guide portion 201. In this embodiment, the cooperation between the guide portion 201 and the U-shaped groove 3011 can limit the movement trajectory of the second movable frame 301 (paper insertion assembly 3) along the length of the longitudinal beam 2, avoiding deviation and jamming when the paper insertion assembly 3 moves, and further ensuring that both paper insertion mechanisms 303 can be aligned with the center hole of the paper roll 14.

[0059] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
