Description

Technical Field

[0001] This application relates to the field of logistics equipment technology, and in particular to a flow rail and storage and transportation module. Background Technology

[0002] Modern warehousing systems and automated logistics equipment are experiencing rapid development, especially in e-commerce and manufacturing. These systems significantly improve the efficiency of goods storage and transportation through efficient space utilization and automated operating processes. Flow racks, as a key component of self-driven modular storage and transportation structures commonly used in industry, not only serve as storage tools but also effectively facilitate short-distance transportation. Combining versatility, efficiency, and economy, they have become an indispensable key piece of equipment in modern warehousing systems.

[0003] Currently, the flow rail structure in self-driven storage and transport modules typically uses equally spaced cylindrical rollers, fixed within a C-frame by embedded bearing housings at both ends. However, in practical applications, roller jamming can occur, especially when the load deviates significantly from the raceway centerline, exacerbating localized roller jamming and leading to a significant decrease in transmission efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a flow strip and a storage and transport module to address the problem of roller jamming in flow strips.

[0005] A fluency bar includes:

[0006] The mounting structure includes a mounting base and a mounting slider. The mounting base has a mounting groove extending longitudinally along the first direction and a mounting port communicating with the mounting groove. The mounting slider is movably disposed on the mounting base along the first direction, and during movement, the mounting slider can enter or exit the mounting groove through the mounting port.

[0007] Multiple support rods are spaced apart from the first direction on the mounting slider, and the axial direction of each support rod intersects the first direction.

[0008] A roller with different diameters is rotatably disposed on the support rod about the axis of the support rod, and has a first rolling part and a second rolling part coaxially disposed with the support rod, wherein the diameter of the first rolling part is larger than that of the second rolling part;

[0009] Each of the support rods is provided with a plurality of rollers of different diameters, and the first rolling portions of two adjacent rollers of different diameters in the first direction are staggered.

[0010] In one embodiment, the mounting slider has a plurality of support blocks spaced apart along a second direction intersecting the first direction, each of the support bars is disposed on all the support blocks, and each of the differential diameter rollers is located between two adjacent support blocks.

[0011] In one embodiment, each of the support blocks is provided with a plurality of support grooves along the first direction, and each of the support grooves penetrates the support block along the second direction, with the support rod passing through one of the support grooves of each of the support blocks.

[0012] In one embodiment, the mounting groove has two protruding fixing parts on its two inner walls opposite each other in the second direction, and the two fixing parts respectively cover all the openings of the support grooves on the two support blocks located at both ends of the second direction.

[0013] In one embodiment, the mounting base is provided with mounting ports at both ends in the first direction.

[0014] In one embodiment, one of the mounting base and the mounting slider has a guide groove extending longitudinally along the first direction, and the other has a guide block, wherein the guide block is located in the guide groove when the mounting groove is located within the mounting groove.

[0015] In one embodiment, the differential roller has a mounting hole extending through it along its own axis, and the support rod passes through the mounting hole.

[0016] In one embodiment, the first rolling portion has a chamfer at at least one end in its longitudinal direction.

[0017] A storage and transport module includes a flow strip as described in any of the preceding claims.

[0018] In one embodiment, the storage and transport module further includes a support, on which the flow strip is disposed and inclined relative to the horizontal direction.

[0019] In actual use, when the aforementioned flow guide is used to transport goods, the goods slide down along multiple rollers of varying diameters. The weight of the goods is then evenly distributed across these rollers. By designating each roller as a first and second rolling section, and using a configuration of half large cylinder and half small cylinder, friction is reduced and rolling performance optimized. This allows even lighter items to roll efficiently at lower tilt angles, effectively reducing the likelihood of roller jamming. Attached Figure Description

[0035] See Figure 1 , Figure 1A schematic diagram of a flow strip structure according to an embodiment of this application is shown. The flow strip provided in an embodiment of this application includes a mounting structure 10, a support rod 20, and a roller with different diameters 30. The mounting structure 10 is used to support the support rod 20 and the roller with different diameters 30. Specifically, the mounting structure 10 includes a mounting base 13 and a mounting slider 14. The mounting base 13 is provided with a mounting groove 15 extending longitudinally along a first direction X and a mounting opening 17 communicating with the mounting groove 15. The mounting slider 14 is movably disposed on the mounting base along the first direction X, and during the movement, the mounting slider 14 can enter or exit the mounting groove 15 through the mounting opening 17.

[0036] The support rods 20 include multiple rods, all of which are spaced apart on the mounting slider 14 along a second direction Y intersecting the first direction X. The axial direction of each support rod 20 intersects the first direction X. Different-diameter rollers 30 are rotatably mounted on the support rods 20 about their axes. It should be noted that, depending on actual usage requirements, the different-diameter rollers 30 can rotate separately from the support rods 20, meaning the different-diameter rollers 30 can rotate relative to the support rods 20 to achieve rotatability about their axes. Alternatively, the different-diameter rollers 30 can rotate simultaneously with the support rods 20, meaning the different-diameter rollers 30 are fixed to the support rods 20 and integrated with them, allowing the different-diameter rollers 30 to rotate together with the support rods 20, thus achieving rotatability about their axes. In actual use, the choice between using the variator roller 30 as an integral part of the support rod 20 or using them separately can be made according to actual usage requirements, and no limitation is made here.

[0037] Each support rod 20 is provided with multiple rollers 30 of different diameters, and each roller 30 of different diameters has a first rolling part 31 and a second rolling part 32 arranged coaxially with the support rod 20, such as Figure 3 As shown, both the first rolling part 31 and the second rolling part 32 are cylindrical, and the diameter of the first rolling part 31 is larger than that of the second rolling part 32. In this way, by using a combination of half large cylinders and half small cylinders, the contact area between the rollers 30 and the goods can be reduced and the weight can be reduced, thereby optimizing the starting performance of the flow rail and reducing energy loss during goods transportation.

[0038] Furthermore, the first rolling portions 31 of two adjacent rollers 30 with different diameters in the first direction X are staggered, that is, in the first direction X, the first rolling portion 31 of one roller 30 with different diameters is spaced apart from the second rolling portion 32 of the other roller 30 with different diameters.

[0039] In actual use, when the aforementioned flow strip is used to transport goods, the goods slide down along multiple rollers 30 of varying diameters. At this time, the weight of the goods is evenly distributed across each roller 30 in contact with the goods. By configuring each roller 30 with a first rolling part 31 and a second rolling part 32, and by using a design that is half large cylinder and half small cylinder, friction is reduced and rolling performance is optimized. This allows even lighter items to roll efficiently at lower tilt angles, effectively reducing the occurrence of roller jamming.

[0040] In some embodiments of this application, the mounting slider 14 has a plurality of support blocks 11 spaced apart along a second direction Y intersecting the first direction X. Each support rod 20 is disposed on all the support blocks 11, and each roller 30 of different diameter is located between two adjacent support blocks 11, that is, the support rod 20 is supported by all the support blocks 11. Since the plurality of support blocks 11 on the mounting structure 10 jointly support the support rod 20, the weight of the goods can be evenly distributed on each support block 11, avoiding the concentration of the weight of the goods on the support rod 20, which would cause the support rod 20 to bend, and reducing the occurrence of roller jamming.

[0041] In some embodiments, in order to fix the support rod 20, each support block 11 is provided with a plurality of support grooves 12 along the first direction X, and each support groove 12 passes through the support block 11 along the second direction Y. The support rod 20 passes through one of the support grooves 12 of each support block 11 so as to fix the support rod 20 through the support grooves 12 on each support block 11.

[0042] Specifically Figure 2 In this embodiment, the mounting structure 10 has four support blocks 11, each forming three support grooves 12. Each support rod 20 is provided with three rollers 30 of varying diameters, which are respectively disposed within the three support grooves 12. The support grooves 12 on the four support blocks 11 are aligned with each other, allowing the support rod 20 to pass sequentially through the support grooves 12 on each support block 11. Optionally, the distance between adjacent support grooves 12 is 6 mm. This arrangement helps ensure a smooth transition of goods and improves transportation efficiency.

[0043] To prevent the support rod 20 from detaching from the support groove 12, the mounting structure 10 includes a mounting base 13 and a mounting slider 14, with multiple support blocks 11 provided on the mounting slider 14. The mounting base 13 has a mounting groove 15 extending longitudinally along the first direction X. The mounting slider 14 is located within the mounting groove 15, and fixing parts 16 protrude from the two opposing inner walls of the mounting groove 15 in the second direction Y. The two fixing parts 16 cover all the openings of the support groove 12 on the two support blocks 11 located at both ends of the second direction Y.

[0044] In other words, the fixing part 16 covers the top of the support groove 12, thereby forming a closure of the support groove 12. Thus, after the mounting slider 14 is installed into the support groove 12, the fixing part 16 can close the openings of the support groove 12 located at both ends of the support rod 20, thereby preventing the support rod 20 from falling out of the support groove 12 and affecting the normal transportation of goods.

[0045] Furthermore, to facilitate the installation of the mounting slider 14 into the mounting groove 15, the mounting base 13 is provided with mounting ports 17 at both ends in the first direction X. The mounting ports 17 are connected to the mounting groove 15, and the mounting slider 14 can enter or exit the mounting groove 15 through the mounting ports 17. In this way, the mounting slider 14 can be easily installed and removed through the mounting ports 17.

[0046] In some specific embodiments, one of the mounting base 13 and the mounting slider 14 is provided with a guide groove 18 extending longitudinally along the first direction X, and the other has a guide block 19. When the mounting groove 15 is located in the mounting groove 15, the guide block 19 is located in the guide groove 18. The cooperation between the guide block 19 and the guide groove 18 makes the process of the mounting slider 14 entering the mounting base 13 smoother.

[0047] In one specific embodiment, a guide block 19 is provided on the mounting base 13, and a guide groove 18 is provided on the mounting slider 14. When the mounting slider 14 is inserted into the mounting base 13 through the mounting port 17, the guide block 19 enters the guide groove 18. Thus, the movement of the guide block 19 in the guide groove 18 guides the movement of the mounting slider 14 on the mounting base 13, thereby making the process of mounting the mounting slider 14 onto the mounting base 13 smoother.

[0048] Optionally, the guide block 19 includes two blocks, which are respectively disposed at both ends of the mounting base 13 in the second direction Y. The guide groove 18 also includes two blocks, which are respectively disposed at both ends of the mounting slider 14 in the second direction Y, and correspond to the two guide blocks 19 respectively.

[0049] In some embodiments of this application, see [reference] Figure 3 Each differential diameter roller 30 has a mounting hole 33 extending along its own axis. A support rod 20 passes through the mounting hole 33 to mount the differential diameter roller 30 onto the support rod 20. The mounting hole 33 and the support rod 20 are coaxially arranged so that the differential diameter roller 30 can rotate around the axis of the support rod 20.

[0050] When the support rod 20 passes through the mounting holes 33 of the multiple variable diameter rollers 30, not only can the multiple variable diameter rollers 30 be installed, but each variable diameter roller 30 can also rotate independently around the support rod 20. In this way, even if one variable diameter roller 30 fails, it will not affect the rotation of the other variable diameter rollers 30, thus ensuring the stability of the entire flow strip during operation.

[0051] In some embodiments of this application, see [reference] Figure 4 The first rolling part 31 has a chamfer 34 at at least one end along its longitudinal direction. In actual use, when transporting goods with holes at the bottom, such as knife boxes, the chamfer 34 can prevent the holes at the bottom of the goods from getting stuck on the first rolling part 31, further improving the smoothness of goods transportation.

[0052] In some embodiments of this application, the diameter of the first rolling part 31 is between 6mm and 9mm, the diameter of the second rolling part 32 is between 2mm and 5mm, preferably, the diameter of the first rolling part 31 is 7.5mm, the diameter of the second rolling part 32 is 3.5mm, the diameter of the support rod 20 is 2.3mm, and the distance between two adjacent support rods 20 is 6mm. The flow strip of this application can transport goods of smaller volume, and reduces jamming of goods during transportation by using the first rolling part 31 and the second rolling part 32 with different diameters, and reduces the phenomenon of denting of the support rod 20 by using multiple support blocks 11.

[0053] This application also provides a storage and transportation module, including the flow strip as described in any of the above embodiments. Since this storage and transportation module includes all the technical features of the flow strip, it possesses all the technical effects of the flow strip, which will not be elaborated further here.

[0054] Furthermore, the storage and transport module also includes a support frame, on which the flow rails are mounted. The flow rails are positioned so that they can be tilted horizontally at an angle of 5°-8°. Compared to the typical 12° installation angle of flow rails, this 5°-8° angle effectively reduces the overall height of the storage and transport module. Specifically, taking a 2m long storage and transport module with 20 layers of flow rails as an example, the flow rails can reduce the equipment height by up to 18.6%, improving the utilization rate of storage space. When this storage and transport module is applied to tool storage, it enables the tool tray to slide down under its own weight at an installation angle of 5°-8°, solving the problem of tray jamming.

[0055] The above-mentioned fluency bar has at least the following effects:

[0056] 1. The rotating support system is reconstructed, and the traditional integrated roller is split into independently rotating support rods 20 and rollers of different diameters 30, so as to disperse the load transmission path and reduce jamming.

[0057] 2. The segmented roller system has a radial gap of 0.3~0.8mm between two adjacent rollers of different diameters 30, which realizes single-segment failure isolation and reduces the failure rate.

[0058] 3. The 30-inch variable diameter roller structure adopts a design with half large cylinder and half small cylinder to reduce the contact area with objects and reduce the weight, thereby optimizing starting performance and energy loss.

[0059] 4. The cross-mounting structure 10 reduces the contact between the item and the side ring of the roller by narrowing the roller spacing, thereby improving rolling efficiency.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
