AI Technical Summary
然而，上述现有主流方案需要集成至少三个核心运动部件：升降驱动机构、平移驱动机构以及精密的同步控制系统，其中，升降机构需要足够的垂直行程空间以抬升货物，平移机构需要足够的横向行程空间以实现货物在两条分拣线之间的跨越，这两部分空间需求叠加，导致转运区域在垂直和水平方向上都需占用大量额外空间，极大的增加了整个输送系统的占地面积，为此，我们提出一种双分拣线用仓储滚筒输送装置
本装置摒弃了传统方案中升降平台与平移机构的组合结构，通过可旋转支架模块的90°旋转直接切换两条分拣线的输送衔接面，无需为货物抬升预留垂直空间，也无需为水平横移设置长行程轨道，整个转运动作在旋转支架的固定回转半径内即可完成，极大压缩了交汇处所需的立体空间，降低了输送系统的整体占地面积；

Description
Technical Field
[0001] This utility model relates to the field of warehousing and sorting technology, specifically to a warehousing roller conveyor device for a dual sorting line. Background Technology
[0002] In the field of warehouse logistics automation, roller conveyor lines have become the core equipment for goods sorting and transportation due to their significant advantages such as simple structure, reliable operation, and convenient maintenance. In specific application scenarios, especially when goods need to be sorted efficiently and accurately to two independent paths (i.e., "dual sorting lines"), the transfer of goods at the intersection of the two sorting lines becomes a critical link.
[0003] Currently, mainstream transfer solutions at the intersection of two sorting lines generally employ a lifting platform at the intersection to elevate goods away from the original conveyor line. Then, using a translation trolley, chain traction mechanism, or similar device, the lifted goods are horizontally moved to directly above the target sorting line. Finally, the lifting platform descends, placing the goods onto the target sorting line to complete the transfer. However, the aforementioned mainstream solutions require the integration of at least three core moving components: a lifting drive mechanism, a translation drive mechanism, and a sophisticated synchronous control system. The lifting mechanism requires sufficient vertical travel space to lift the goods, and the translation mechanism requires sufficient lateral travel space to allow the goods to cross between the two sorting lines. The overlap of these two space requirements results in the transfer area occupying a large amount of additional space in both the vertical and horizontal directions, significantly increasing the footprint of the entire conveying system. To address this, we propose a storage roller conveyor device for dual sorting lines. Utility Model Content
[0004] The purpose of this invention is to provide a storage roller conveyor for a dual sorting line to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a storage roller conveyor device for a dual sorting line, comprising a frame and roller conveyor lines mounted on the frame; the roller conveyor lines include a first sorting line and a second sorting line perpendicular to each other; a rotatable support module is provided at the intersection of the two sorting lines; the rotatable support module includes: a rotating support, the bottom of which is mounted on the ground via a support base, the support base having a rotating shaft that can rotate around an axis, the rotating support being fixedly connected to the outside of the rotating shaft, the axis of the rotating shaft being parallel to the horizontal plane; an L-shaped frame, fixedly mounted on the outside of the rotating support; a first set of conveying rollers, mounted on the horizontal plane of the L-shaped frame, with the conveying direction parallel to the first sorting line; a second set of conveying rollers, mounted on the vertical plane of the L-shaped frame, with the conveying direction parallel to the second sorting line and perpendicular to the first set of conveying rollers; and a drive switching mechanism, which drives the rotating support to rotate 90° around the rotating shaft in the vertical plane, so that the bearing surface of the first set of conveying rollers is flush with the conveying surface of the first sorting line, or so that the bearing surface of the second set of conveying rollers is flush with the conveying surface of the second sorting line.
[0006] Preferably, the rotating bracket and the L-shaped frame are connected by L-shaped baffles; there are two L-shaped baffles, both located inside the L-shaped frame, and the distance between the two L-shaped baffles matches the outer contour of the rotating bracket; the L-shaped baffles are fastened to the rotating bracket by fixing bolts.
[0007] Preferably, the rotating shaft is located at the center of the rotating bracket.
[0008] Preferably, the drive switching mechanism includes a drive motor and a gearbox; the output end of the gearbox is connected to a rotating shaft, and the input end is connected to the output end of the drive motor; both the drive motor and the gearbox are fixed to the ground by a base.
[0009] Preferably, the support base has a U-shaped structure.
[0010] Preferably, L-shaped baffles are symmetrically distributed on both sides of the rotating support.
[0011] Preferably, the rotating shaft inside the support base is fixed coaxially with the rotating bracket.
[0012] Preferably, the drive motor and the gearbox base are set separately.
[0013] Compared with traditional technologies, the beneficial effects of this utility model are: This device abandons the combination structure of lifting platform and translation mechanism in traditional solutions. It directly switches the conveying interface of two sorting lines by rotating the 90° bracket module. There is no need to reserve vertical space for lifting goods or set up long-stroke tracks for horizontal movement. The entire transfer action can be completed within the fixed turning radius of the rotating bracket, which greatly reduces the three-dimensional space required at the intersection and reduces the overall footprint of the conveying system. Traditional solutions rely on multiple independent systems such as lifting, translation, and synchronous control to work together. However, this device only needs to drive a single motion unit of the rotating support to realize the sorting line switching function, eliminating the complex lifting mechanism, translation trolley, and multi-axis linkage control system. The overall structure is more compact and reliable, reducing equipment manufacturing costs and subsequent maintenance difficulties.
[0014] The first and second sets of conveyor rollers are fixed to the outside of the rotating bracket by fixing bolts, which facilitates the disassembly, maintenance and replacement of the first and second sets of conveyor rollers. Attached Figure Description

Detailed Implementation
[0017] 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.
[0018] Example 1: Please see Figures 1-4The diagram illustrates a storage roller conveyor device for a dual sorting line, comprising a frame 1 and roller conveyor lines mounted on the frame 1; the roller conveyor lines include a first sorting line 2 and a second sorting line 3 that are perpendicular to each other; a rotatable support module 4 is provided at the intersection of the two sorting lines; the rotatable support module 4 includes: a rotating support 5, the bottom of which is mounted on the ground via a support base 6, the support base 6 having a rotating shaft 7 that can rotate around an axis, the rotating support 5 being fixedly connected to the outside of the rotating shaft 7, the axis of the rotating shaft 7 being parallel to the horizontal plane; and an L-shaped frame 8, fixedly mounted on the rotating support. The rotating support 5 has the following components: a first set of conveyor rollers 9, located on the horizontal plane of the L-shaped frame 8, with a conveying direction parallel to the first sorting line 2; and a second set of conveyor rollers 10, located on the vertical plane of the L-shaped frame 8, with a conveying direction parallel to the second sorting line 3 and perpendicular to the first set of conveyor rollers 9. A drive switching mechanism 11 drives the rotating support 5 to rotate 90° around the rotating shaft 7 in the vertical plane, so that the bearing surface of the first set of conveyor rollers 9 is flush with the conveying surface of the first sorting line 2, or so that the bearing surface of the second set of conveyor rollers 10 is flush with the conveying surface of the second sorting line 3. The drive switching mechanism 11 drives the support to rotate precisely 90° around the rotating shaft 7 in the vertical plane, allowing one of the bearing surfaces of the two sets of rollers to be flush with the corresponding sorting line conveying surface, achieving seamless directional transfer of goods between the two sorting lines.
[0019] The following describes some embodiments of this application in detail with reference to the accompanying drawings: Please see Figures 1-4 The conveying interface between the two sorting lines can be directly switched by rotating the rotatable bracket module 4 by 90°. There is no need to reserve vertical space for lifting goods or set up long-stroke tracks for horizontal movement. The entire transfer action can be completed within the fixed turning radius of the rotating bracket 5, which greatly reduces the three-dimensional space required at the intersection and reduces the overall footprint of the conveying system.
[0020] The rotating bracket 5 and the L-shaped frame 8 are connected by an L-shaped baffle 12. There are two L-shaped baffles 12, both located inside the L-shaped frame 8. The distance between the two L-shaped baffles 12 matches the outer contour of the rotating bracket 5. The L-shaped baffles 12 are fastened to the rotating bracket 5 by fixing bolts 13 to ensure that the L-shaped frame 8 does not deform or shift when bearing the conveying load during rotation, while simplifying the modular assembly and disassembly process. Meanwhile, the rotating shaft 7 is located at the center of the rotating support 5, allowing the support to rotate around its geometric central axis. The central axis layout ensures that the rotation radii of the first and second sets of conveyor rollers 10 are the same, guaranteeing that the linear velocities of the two sets of rollers are consistent when the support rotates. This ensures that the conveyor rollers can be aligned with the corresponding sorting line after rotation, thereby ensuring the smoothness of the goods transportation process. Furthermore, the rotating shaft 7 inside the support base 6 is coaxially fixed with the rotating bracket 5 to ensure that the driving torque is transmitted to the bracket without loss, avoid bearing wear or rotation jamming caused by axis deviation, and extend the service life of the equipment.
[0021] In addition, L-shaped baffles 12 are symmetrically distributed on both sides of the rotating bracket 5, forming a double-sided clamping and fixing mechanism. The symmetrical layout ensures that the preload of the fixing bolts 13 is evenly transmitted to the main body of the bracket, eliminating the risk of stress concentration on one side, ensuring that there is no gap between the contact surface of the L-shaped frame 8 and the bracket, and avoiding structural loosening caused by rotational vibration.
[0022] It is worth noting that the support base 6 has a U-shaped structure. The U-shaped design provides three-dimensional constraints, effectively resisting the radial load and overturning moment of the rotating bracket 5, while facilitating the maintenance of the rotating shaft 7. Its wide bottom shape disperses ground pressure and can prevent axial deviation caused by foundation settlement.
[0023] In this technical solution, the drive switching mechanism 11 includes a drive motor 14 and a reduction gearbox 15; the output end of the reduction gearbox 15 is connected to the rotating shaft 7, and the input end is connected to the output end of the drive motor 14; both the drive motor 14 and the reduction gearbox 15 are fixed to the ground by the base 16, and the reduction gearbox 15 converts the high-speed output of the motor into high-torque low-speed rotation to ensure that the bracket can start and stop smoothly and accurately position the angle.
[0024] The working principle of this device is as follows: When the device is in its initial position, the horizontal plane of the L-shaped frame 8 of the rotating support 5 is flush with the conveying surface of the first sorting line 2, and the first set of conveying rollers 9 is in the working position. Goods are conveyed from the front section of the first sorting line 2 to the area of the rotating support 5, and then supported by the first set of conveying rollers 9 and output to the rear section of the first sorting line 2. The support base 6 provides stable support through the internal rotating shaft 7, while the drive motor 14 and the gearbox 15 are in standby mode. If goods need to be transferred to the second sorting line 3 in the vertical direction, the control system triggers the drive motor 14 to output power, which is converted into high-torque rotary motion through the reduction gearbox 15; the output end of the reduction gearbox 15 drives the rotating shaft 7 to rotate; the rotating shaft 7 drives the rotating bracket 5 and the outer L-shaped frame 8 to rotate 90° around the axis in the vertical plane. The L-shaped baffle 12 can ensure that the frame and the bracket rotate rigidly and synchronously, avoiding structural deformation; When the rotating support 5 reaches the target position, the bearing surface of the second set of conveying rollers 10 is precisely aligned with the conveying surface of the second sorting line 3; the second set of conveying rollers 10 starts and conveys the goods to the second sorting line 3 in a vertical direction; after the transfer is completed, the drive switching mechanism 11 rotates the support 5 in the opposite direction to reset it by 90°, waiting for the next operation.
[0025] When maintenance or replacement of the first set of conveyor rollers 9 and the second set of conveyor rollers 10 is required, simply unscrew the fixing bolts 13 to remove the conveyor rollers and L-shaped frame 8 from the rotating bracket 5, without disassembling the rotating bracket 5 and the support base 6.
[0026] Example 2: This embodiment is an optimization of the structure in Embodiment 1. Specifically, as follows: Figure 2 As shown, the drive motor 14 and the base 16 of the gearbox 15 are separated to block the transmission of motor vibration to the gearbox 15 and prevent damage to the gear meshing accuracy; at the same time, space is reserved for motor heat dissipation to avoid heat accumulation affecting the lubrication performance of the gearbox 15.
