Description

Technical Field

[0001] This utility model belongs to the technical field of polarizer production equipment, and more specifically, it relates to a roller transfer device and system, and a polarizer production system. Background Technology

[0002] The manufacturing process of polarizers involves multiple steps (such as coating, wet stretching, drying, and bonding). Among these, the wet stretching process is the core step in polarizer production. For example... Figure 1 As shown, in the polarizer manufacturing process, production equipment 40' mainly achieves the wet stretching process through roller 50'. The original film is stretched to the target width at a fixed width. Due to the requirements of the stretching process, the front roller 50' in production equipment 40' is generally designed to be wider. However, during the production process, due to the gradual accumulation of iodine solution crystals and PVA residues in the wet process, long-term operation leading to micro-deformation of the roller 50' and bearing wear, and scratches caused by surface coating wear, roller 50' needs to be disassembled and replaced periodically for maintenance. However, due to the wide design of the front roller 50' and the limited factory space, roller 50' cannot be directly pulled out laterally from the operating side.

[0003] Traditional maintenance methods rely on the overhead crane 10' and the curved exit rail 20'. The removed roller 50' needs to be moved outwards along the curved rail 20'. However, due to the heavy weight of the roller 50' and the fixed stroke of the curved rail 20', when the roller 50' moves, its front pulley enters the curved rail 20' first and turns along its trajectory. This process easily causes a lateral shift in the roller 50's center of gravity, requiring eight people to push and pull it to move. After turning along the curved rail 20', the roller 50' still needs to continue moving along the straight rail. However, the curved rail 20' and the straight rail are generally joined by welds, and the roller 50' is prone to jamming at the weld. Both the shift in the center of gravity and the jamming make it difficult to push the roller 50', resulting in a high risk factor. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a roller transfer device and system, and a polarizer production system, which aims to reduce the dangers in the roller transfer process.

[0005] On one hand, a roller conveying device is provided, including a device body, a rotating structure and a carrier. The device body has a plurality of casters at its bottom. The rotating structure is installed in the vertical extension direction of the device body. The carrier is installed in the vertical extension direction of the rotating structure and has a limiting groove on its top for limiting the rollers.

[0006] In some possible implementations, the roller transfer device further includes a buffer layer disposed within the limiting groove.

[0007] In some possible implementations, the carrier can rotate 360° about the axis of the rotating structure.

[0008] In some possible implementations, the limiting groove is disposed along a first direction, and the limiting groove extends to the sidewall of the carrier at both ends in the first direction.

[0009] In some possible implementations, the bottom surface of the limiting groove is an arc-shaped surface.

[0010] In some possible implementations, the main body of the equipment includes a frame and a lifting mechanism, the lifting mechanism being located between the rotating structure and the frame, and the casters being located at the bottom of the frame.

[0011] In some possible implementations, the frame has protective components, which are provided in two sets, with the two sets of protective components located on both sides of the lifting mechanism.

[0012] Secondly, a roller transfer system is provided, including a hoisting device and a roller transfer device. The hoisting device is used to lift the roller to be maintained and transfer it to the roller transfer device, and is also used to transfer the maintained roller transported by the roller transfer device to the production equipment.

[0013] In some possible implementations, the hoisting equipment is multiple; and / or, the roller transfer equipment is multiple.

[0014] Thirdly, a polarizer production system is provided, including production equipment and a roller transfer system, wherein the production equipment has rollers;

[0015] The length of the limiting groove is less than the length of the roller, and the width of the limiting groove is greater than the maximum diameter of the roller.

[0016] The technical solution provided in the first aspect above has the following beneficial effects: Compared with the prior art, the roller transfer equipment provided by this utility model embodiment can eliminate the need for curved rails, reduce space occupation, and lower purchase costs; moreover, during the roller angle adjustment process, it is not necessary to move the roller, and under the limitation of the limiting groove, the roller will not move relative to the carrier during the entire adjustment process, so that the center of gravity of the roller is always on the roller transfer equipment and does not change. The above-mentioned operation of rotating the carrier can be achieved with the help of a power device or a small amount of manual labor, and it is easy to operate, which can reduce the labor intensity and danger of roller transfer operation and improve the work efficiency of roller transfer and maintenance.

[0017] The beneficial effects of the second and third aspects are the same as those of the first aspect, and will not be repeated here. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] Please refer to the following: Figures 2 to 4 The roller transfer device 10 provided in this embodiment of the present invention will now be described. The roller transfer device 10 includes a main body 11, a rotating structure 12, and a support member 13. The bottom of the main body 11 has a plurality of casters 113. The rotating structure 12 is installed in the vertical extension direction of the main body 11. The support member 13 is installed in the vertical extension direction of the rotating structure 12, and a limiting groove 14 is formed at the top for limiting the rollers 31.

[0031] The main body 11 of the equipment has a height direction Z. The vertical extension direction is the height direction Z. A rotating structure 12 is provided on the main body 11, and the axial direction of the rotating structure 12 is arranged along the height direction Z. A support member 13 is rotatably provided on the main body 11 via the rotating structure 12. The support member 13 is provided with a limiting groove 14. The limiting groove 14 is used to accommodate at least a portion of the roller 31 to limit the relative position of the roller 31 and the support member 13.

[0032] The main body 11 is the main component of the roller conveying device 10, and can be composed of one or more parts, modules, etc. For example, in some embodiments, the main body 11 can be composed of a frame, casters, etc.; in other embodiments, the main body 11 can be composed of a frame, a lifting mechanism 112, casters, etc. The main body 11 in this embodiment can be configured in various ways, depending on the specific needs of use.

[0033] The rotating structure 12 can be composed of one or more components. The rotating structure 12 can be fixedly installed on the equipment body 11 or rotated on the equipment body 11, depending on the usage requirements.

[0034] It is understandable that when the rotating structure 12 is fixedly installed on the equipment body 11, the bearing member 13 is rotatably mounted on the equipment body 11 through the rotating structure 12, meaning that the bearing member 13 is rotatably connected to the rotating structure 12 and can rotate around the axis of the rotating structure 12 at a certain angle (such as 90°, 180°, 360°, etc.). When the rotating structure 12 is rotatably mounted on the equipment body 11, the bearing member 13 is rotatably mounted on the equipment body 11 through the rotating structure 12, meaning that the rotating structure 12 is rotatably connected to the equipment body 11, and the rotating structure 12 can rotate around its own axis at a certain angle (such as 90°, 180°, 360°, etc.), while the bearing member 13 is fixedly connected to the rotating structure 12 and can rotate relative to the equipment body 11 at a certain angle under the drive of the rotating structure 12.

[0035] The aforementioned support member 13 is a component used to support the roller 31, and can be composed of one or more parts, depending on the specific needs of use.

[0036] The limiting groove 14 is generally provided on the surface of the bearing member 13 that contacts the roller 31. The dimension of the limiting groove 14 in the length direction is smaller than the dimension of the roller 31, so that the roller transfer device 10 can be placed in the space between the polarizer production equipment 30 and the wall. In addition, the dimension of the limiting groove 14 in the depth direction is also smaller than the diameter of the roller 31, which facilitates the insertion and removal of the roller 31. The dimension of the limiting groove 14 in the width direction is generally larger than the diameter of the roller 31, so that the roller 31 can be placed in the limiting groove 14.

[0037] Figure 5 A schematic diagram of the polarizer production system in use provided in this embodiment of the utility model; Figure 6 This is a structural diagram illustrating the usage state of the roller transfer system provided in this embodiment of the present invention when hoisting and transferring rollers to the roller transfer equipment. The working principle of the roller transfer equipment 10 provided in this embodiment of the present invention is as follows: Figure 5 and Figure 6 As shown:

[0038] When roller 31 needs maintenance, first use the hoisting equipment 20 (including overhead crane) to lift the roller 31 to be maintained, then use the hoisting equipment 20 to place a part of the roller 31 into the limiting groove 14, then rotate the bearing member 13 to drive the roller 31 to adjust the angle, then use the universal wheel 113 to rotate to the direction of the roller transfer equipment 10 to adjust the angle of the roller 31, and then transfer the roller 31 to the maintenance station.

[0039] Therefore, the roller transfer device 10 provided in this embodiment of the present invention eliminates the need for curved rails, and during the adjustment of the roller 31 angle, there is no need to move the roller 31. Furthermore, under the constraint of the limiting groove 14, the roller 31 will not move relative to the bearing member 13 throughout the entire adjustment process, ensuring that the center of gravity of the roller 31 remains on the roller transfer device 10 and does not change. The aforementioned operation of rotating the bearing member 13 can be achieved with the aid of a power device or with minimal manual labor, and is easy to operate. Using the roller transfer device 10 provided in this embodiment of the present invention can reduce the labor intensity and danger of roller 31 transfer operations, and improve the efficiency of roller 31 transfer and maintenance.

[0040] Furthermore, in related technologies, due to the large number of rollers, curved rails are required at each corresponding position, resulting in a large number of curved rails in the workshop, occupying a lot of space, and increasing the equipment purchase cost. The roller transfer device 10 provided in this embodiment of the invention eliminates the need for curved rails, thereby reducing space occupation and lowering purchase costs.

[0041] In some embodiments, the roller conveying device 10 further includes a buffer layer 15. The buffer layer 15 is disposed within the limiting groove 14.

[0042] The buffer layer 15 is a flexible material layer covering the surface of the limiting groove 14, used to absorb impact, reduce vibration, or isolate physical / chemical effects. The buffer layer 15 can be made of foam, rubber pads, etc., depending on the application requirements.

[0043] The buffer layer 15 can absorb the impact of the roller 31 on the carrier 13, reduce the risk of hard collision between the roller 31 and the carrier 13, and protect the roller 31 and the carrier 13.

[0044] In some embodiments, the carrier 13 is capable of rotating 360° about the axis of the rotating structure 12.

[0045] This makes it easier for the bearing component 13 to drive the roller 31 to adjust to the required placement angle.

[0046] like Figure 4 As shown, in some embodiments, the limiting groove 14 is disposed along the first direction X, and both ends of the limiting groove 14 extend to the sidewall of the support member 13 in the first direction X. That is, the limiting groove 14 is a through groove with open ends.

[0047] The first direction X can be the length direction of the carrier 13, or the width direction of the carrier 13, or other directions that form a certain angle with the length direction of the carrier 13. The specific direction can be determined according to the usage requirements.

[0048] The limiting groove 14 is an open through groove at both ends, which allows the two ends of the roller 31 to extend out of the limiting groove 14 when the roller 31 is placed, making it easier to place the roller 31. It also allows the bearing member 13 to be placed stably without having to be too large.

[0049] In some embodiments, the bottom surface of the limiting groove 14 is an arc-shaped surface.

[0050] The curvature of the arc surface can be determined based on the diameter of the roller 31.

[0051] In this embodiment, the cross-section of the limiting groove 14 can be U-shaped, C-shaped, or other shapes that meet the usage requirements.

[0052] This allows the bottom surface of the limiting groove 14 to match the wheel surface of the roller 31, which helps to increase the contact area between the limiting groove 14 and the roller 31, as well as the friction between them, making it easier to place the roller 31 stably.

[0053] like Figure 2 and Figure 3As shown, in some embodiments, the main body 11 of the equipment includes a frame 111 and a lifting mechanism 112. The lifting mechanism 112 is located between the rotating structure 12 and the frame 111, and the casters 113 are located at the bottom of the frame 111.

[0054] The lifting mechanism 112 can be a hydraulic lifting mechanism, an electric cylinder lifting mechanism, or other lifting mechanisms, depending on the application requirements.

[0055] The lifting mechanism 112 facilitates the adjustment of the height of the support component 13, while the casters 113 facilitate the movement of the roller transfer device 10 according to usage needs. Therefore, the lifting mechanism 112 and the casters 113 improve the ease of use of the roller transfer device 10.

[0056] In some embodiments, the frame 111 has protective members 114. Two sets of protective members 114 are provided, and the two sets of protective members 114 are respectively disposed on both sides of the lifting mechanism 112.

[0057] The protective component 114 can be composed of one or more parts, such as a plate, multiple rods spliced ​​together, or other shapes or structures, depending on the specific needs of use.

[0058] The protective component 114 reduces the risk of users coming into contact with the lifting mechanism 112 and the rotating structure 12 and the load-bearing component 13 on the lifting mechanism 112, thereby improving the safety of the roller transfer equipment 10.

[0059] Another embodiment of this utility model provides a roller transfer system. For example... Figure 5 and Figure 6 As shown, the roller transfer system includes a hoisting device 20 and a roller transfer device 10 provided in any of the above embodiments. The hoisting device 20 is used to lift and transfer the roller 31 to be maintained to the roller transfer device 10, and is also used to transfer the maintained roller transported by the roller transfer device 10 to the production equipment 30.

[0060] In some embodiments, the hoisting equipment 20 has multiple components.

[0061] This allows different lifting equipment 20 to correspond to different rollers 31, enabling the lifting of multiple rollers 31 simultaneously, which helps improve the transfer efficiency of rollers 31.

[0062] In some embodiments, the roller transfer device 10 has multiple rollers.

[0063] Multiple roller transfer devices 10 can be used in conjunction with the same hoisting device 20 to improve the transfer efficiency of rollers 31.

[0064] Another embodiment of this utility model provides a polarizer production system. For example... Figure 5 As shown, the polarizer production system includes production equipment 30 and a roller transfer system. Production equipment 30 has rollers 31. The roller transfer system is used to transfer rollers 31. The length of the limiting groove 14 is less than the length of the roller 31, and the width of the limiting groove 14 is greater than the maximum diameter of the roller 31.

[0065] This facilitates the placement of roller 31, allows the roller transfer system to be used in environments with limited factory space, and makes the maintenance of roller 31 easier, thereby ensuring the yield rate of polarizers and making the production efficiency of polarizers higher.

[0066] Please refer to the following: Figures 3 to 5 As a specific embodiment of the roller transfer system provided by this utility model, the roller transfer system includes a hoisting device 20 and a roller transfer device 10 provided in any of the above embodiments. The hoisting device 20 includes one straight overhead crane and two hand-operated hoists.

[0067] The roller conveying device 10 includes a main body 11, a rotating structure 12, a support member 13, and a buffer layer 15. The main body 11 has a height direction Z. The main body 11 includes a frame 111, a lifting mechanism 112, and casters 113. The lifting mechanism 112 is mounted on the frame 111. The casters 113 are located at the bottom of the frame 111. The rotating structure 12 is axially arranged along the height direction Z and is located at the top of the lifting mechanism 112. The support member 13 is rotatably mounted on the main body 11 via the rotating structure 12. The support member 13 is capable of rotating 360° around the axial direction of the rotating structure 12. The support member 13 is provided with a limiting groove 14. The limiting groove 14 is used to accommodate at least a portion of the roller 31 to limit the relative position of the roller 31 and the support member 13. The buffer layer 15 is located within the limiting groove 14. The limiting groove 14 is arranged along a first direction, and both ends of the limiting groove 14 extend to the sidewalls of the support member 13 in the first direction. The limiting groove 14 is a through groove open at both ends. The cross-section of the limiting groove 14 is U-shaped or C-shaped. The frame 111 has protective components 114. There are two sets of protective components 114, which are respectively located on both sides of the lifting mechanism 112.

[0068] The aforementioned casters 113 include six omnidirectional casters to ensure that the roller conveyor 10 can move 360°. The protective component 114 facilitates the operation of the entire roller conveyor 10 and also protects the operator's safety.

[0069] The lifting mechanism 112 includes a support arm and a hydraulic cylinder. A hydraulic pump and a motor are installed on one side of the frame 111. The motor drives the hydraulic pump, which controls the hydraulic cylinder. The extension and retraction of the hydraulic cylinder controls the support arm to open and rise to any height within the range.

[0070] An upper frame is mounted on the support arm, and a rotating structure 12 is mounted on the upper frame. The rotating structure 12 includes a rotary bearing. The rotary bearing is located on the upper frame, and a turntable is mounted on the rotary bearing. The turntable is the aforementioned load-bearing component 13. A foam pad (i.e., the aforementioned buffer layer 15) is mounted on the turntable. This ensures that the turntable and the foam pad rotate with the lower frame 111 via the rotary bearing.

[0071] When disassembling roller 31, two hand-operated hoists pull both ends of roller 31 and move it outwards until the front end of roller 31 moves out. Then, a roller transfer device 10 supports roller 31, allowing roller 31 to fall radially into the limiting groove 14 of the support member 13. Roller transfer device 10 then moves laterally via its casters 113, and the support member 13 drives roller 31 to rotate slowly. Once the rear end of roller 31 moves out, detaches from its position in the equipment space, and is placed on another roller transfer device 10, the disassembly of roller 31 is complete.

[0072] The roller conveyor 10 forms a multi-directional combination with the universal wheels below and the rotary bearing above, which can ensure the 360° movement of the roller conveyor 10 and cooperate with the 360° movement of the upper load (such as roller 31), without the two interfering with each other.

[0073] The roller transfer device 10 can be used in confined spaces, enabling the disassembly, assembly, and transfer of rollers 31 even in situations with limited space. During this process, the center of gravity of the roller 31 remains on the roller transfer device 10. It can also be raised and offset to ensure the safety of the equipment and personnel involved in roller 31 installation; similarly, it improves replacement efficiency and reduces the number of personnel required for replacement. Using the roller transfer device 10, the number of installation personnel can be reduced from 8 to 4.

[0074] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
