Description

Technical Field

[0001] This utility model belongs to the field of roller transfer technology, specifically, it relates to a double-layer roller transfer machine. Background Technology

[0002] Roller transfer machines are automated logistics conveying equipment that integrates conveying, lifting, and transfer functions. They primarily use a roller conveyor system to carry goods, employing a lifting mechanism (hydraulic, electric, or pneumatic) to vertically elevate the goods, and then transferring them laterally to the target workstation or conveyor line via belts, chains, or other transfer devices. Their key features include high-precision docking capabilities, adaptability to various carriers such as boxes and pallets, and widespread application in logistics sorting, production line docking, and warehousing transfer scenarios to improve the automation and efficiency of material handling. With the increasing demand for mechatronics integration and industry upgrading, the frequency of use of roller transfer machines is rising, and their transport capacity is also increasing.

[0003] Patent CN213474386U discloses a roller transfer machine. Roller conveyors are movably installed on both the left and right sides inside a fixed base frame. Telescopic cylinders, air cylinders, and transfer frames are set on both sides. The main motor installed on the fixed base frame facilitates the start of the main motor to drive the drive gear. The drive gear then transmits the motion to the driven gear meshing with it. The driven gear, under force, drives the rotating shaft and drive wheel to rotate. The rotating drive wheel drives the conveyor belt to rotate, and the conveyor belt transports the material on the top of the transfer frame away. This achieves the systematized loading and transfer effect, avoiding the complex structure of existing roller transfer machines that cannot achieve efficient loading and transfer.

[0004] In the above-mentioned patented technical solution, the efficient loading and transfer effect of the roller transfer machine is improved by improving the drive and transmission structure related to the roller transfer machine. However, it still uses the traditional single-layer roller transfer machine. The single-layer roller transfer machine has a limited conveying capacity and low conveying efficiency. Single-layer conveying cannot meet the needs of normal operation, resulting in relatively low overall transportation efficiency and certain limitations. Utility Model Content

[0005] To address the limitations of existing roller transfer machines, which are mostly single-layer conveying structures with limited conveying capacity, resulting in low conveying efficiency and inability to meet normal operating requirements, this invention provides a double-layer roller transfer machine.

[0006] The objective of this utility model can be achieved through the following technical solutions: A double-layer roller transfer machine includes a base frame, with a conveyor frame mounted on the upper part of the base frame; multiple evenly distributed fixed frames are arranged along the length of the conveyor frame, and each fixed frame is equipped with two longitudinally arranged rollers; a conveyor motor is mounted on the lower part of one fixed frame of the conveyor frame, and two sprockets are mounted on the conveying end of the conveyor motor; two sprockets are mounted on the end of each roller near the conveyor motor; a second chain meshing with the sprockets of the rollers and the sprockets of the conveyor motor is mounted together.

[0007] Furthermore, a lifting motor is installed near the center of the base frame; both ends of the base frame are rotatably connected to longitudinally arranged drive shafts; a sprocket is fixedly installed at the end of the drive shaft near the output end of the lifting motor; two sprockets are fixedly installed on the output shaft of the lifting motor; a meshing first chain is provided on the sprockets of the drive shaft and the sprockets of the output shaft of the lifting motor; swing arms are fixedly connected to both ends of the drive shaft; connecting blocks corresponding to the four corners of the lower surface of the conveyor frame are provided, and the lower part of the connecting blocks is connected to the swing arms.

[0008] Furthermore, a proximity switch assembly is provided at one end of the base frame.

[0009] Furthermore, lifting holes are provided at both ends of the conveyor frame.

[0010] Furthermore, diffuse reflective photoelectric components are provided on the upper part of the fixed frame at the end of the conveyor frame away from the proximity switch assembly.

[0011] Furthermore, the conveyor frame is provided with two end face blocking components near the diffuse reflective photoelectric component.

[0012] Furthermore, the conveyor frame is provided with multiple side movable components on the side away from the second chain.

[0013] The beneficial effects of this utility model are: 1. This utility model achieves conveying by setting a sprocket at one end of each roller and connecting it to the conveyor motor via a chain. The double-layer roller configuration improves the shortcomings of roller transfer machines, increases the conveying capacity, and facilitates the conveying of goods by operators. It solves the technical problem that existing roller transfer machines are mostly single-layer conveying structures with limited conveying capacity, resulting in low conveying efficiency and failure to meet normal working needs, thus having certain limitations. The structure is simple, easy to operate, and increases practicality.

[0014] 2. This utility model installs a lifting motor and a drive shaft on the base frame. The rotation of the lifting motor drives the drive shaft to rotate, and the drive shaft drives the swing arm to achieve lifting and lowering. When the lifting motor rotates, it can drive the swing arm to raise the conveyor frame. When the lifting motor rotates once, the conveyor frame can be lowered. The swing arm connects the double-layer rollers with the target workstation or conveyor line with high precision, realizing the purpose of transferring goods laterally to the target workstation or conveyor line. It is convenient and fast, improves the efficiency of conveying, and achieves precise conveying.

[0015] 3. This utility model enables precise position detection, flexible guidance and positioning, reliable blocking and smooth transfer of goods during the conveying process by setting diffuse reflective photoelectric components, proximity switch components, side movable components and end face blocking components on or around the conveyor frame. These components are linked through a PLC or control system to ensure the continuity and stability of goods in the automated logistics process, effectively prevent deviation, jamming or falling, and improve sorting and docking accuracy and overall efficiency.

[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] Please see Figure 1 - Figure 4As shown, a double-layer roller transfer machine includes a base frame 1, on which a lifting motor 10 is mounted near the center; both ends of the base frame 1 are rotatably connected to longitudinally arranged drive shafts 15; a sprocket is fixedly mounted on one end of the drive shaft 15 near the output end of the lifting motor 10; two sprockets are fixedly mounted on the output shaft of the lifting motor 10; a first chain 11 meshes with both the sprockets of the drive shaft 15 and the sprockets of the output shaft of the lifting motor 10, and the lifting motor 10 drives the drive shaft 15 through the cooperation of the sprockets and the first chain 11; and swing arms 14 are fixedly connected to both ends of the drive shaft 15.

[0019] The base frame 1 is equipped with proximity switch assemblies 3 at both ends. Each proximity switch assembly 3 consists of a bracket and a photoelectric sensor, and three of them are provided. They are used for non-contact detection of the precise position of the moving platform, stage, or actuator. When the metal trigger plate on the moving part of the equipment enters the sensing area, the switch generates an electrical signal through electromagnetic induction (inductive) or capacitance change (capacitive) principle, which is fed back to the PLC or control system in real time to realize travel limit, origin positioning, reciprocating motion control, or anti-collision protection, ensuring the synchronization and safety of the transfer action.

[0020] A conveyor frame 8 is provided on the upper part of the base frame 1. The conveyor frame 8 has a side-mounted U-shaped structure. Connecting blocks 16, corresponding to the swing arms 14, are provided at the four corners of the lower surface of the conveyor frame 8, and the lower parts of the connecting blocks 16 are connected to the swing arms 14. Lifting holes 2 are provided at both ends of the conveyor frame 8, which facilitate the binding of the base frame 1 and the conveyor frame 8 during lifting. Multiple evenly distributed fixing frames 13 (eight in this embodiment) are provided along the length of the conveyor frame 8, and each fixing frame 13 has two... The longitudinally arranged rollers 4 and the fixed frame 13 at the end of the conveyor frame 8 away from the proximity switch assembly 3 are both equipped with diffuse reflective photoelectric components 7. The diffuse reflective components consist of a bracket and a diffuse reflective photoelectric sensor, which are used for non-contact detection of the passage, presence or precise position of objects. When the goods pass through the detection area, their surface reflects the light emitted by the sensor to the receiver, triggering a switch signal and feeding it back to the PLC control system, realizing dynamic counting, package arrival detection and start / stop control of the conveying process in logistics sorting, ensuring the continuity and accuracy of the automated transfer process.

[0021] A conveyor motor 9 is provided at the lower part of the fixed frame 13 near the proximity switch assembly 3 of the conveyor frame 8, and two sprockets are provided on the conveying end of the conveyor motor 9; two sprockets are provided on the roller 4 near the end of the conveyor motor 9; a second chain 12 is provided on the sprockets of the roller 4 and the sprockets of the conveyor motor 9, and the conveyor motor 9 drives the roller 4 through the cooperation of the second chain 12 and the sprockets.

[0022] Two end-face blocking components 6 are provided near the end of the conveyor frame 8 close to the diffuse reflective photoelectric component 7. The end-face blocking component 6 consists of an aluminum profile support frame fixed to the ground by expansion bolts and two baffles. It is used to accurately position and block the goods after the diffuse reflective photoelectric component 7 detects that the goods have arrived, preventing them from continuing to move forward due to inertia or sudden equipment stop, thus preventing them from sliding off the conveyor frame 8 or falling off. Multiple side movable components 5 (three in this embodiment) are provided on the side of the conveyor frame 8 away from the second chain 12. The side movable components 5 consist of cylinders and rollers, used to flexibly guide, laterally position or correct the goods during the conveying process. When the goods are running on the roller conveyor, these components can apply controllable lateral pressure through pneumatic, electric or spring loading to prevent the goods from shifting, colliding or jamming due to inertia, vibration or changes in conveying speed. At the same time, it ensures that the goods maintain a precise queue position during transfer, sorting or turning, improving the stability and efficiency of the automated process.

[0023] To facilitate understanding of the above-mentioned technical solution of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below: This utility model achieves conveying by setting a sprocket at one end of each roller 4 and connecting it to the conveying motor 9 via a chain. The double-layer roller 4 configuration improves the shortcomings of roller 4 transfer machines, increases the conveying capacity, and facilitates the conveying of goods by operators. It solves the technical problem that existing roller 4 transfer machines are mostly single-layer conveying structures with limited conveying capacity, resulting in low conveying efficiency and inability to meet the needs of normal operation. The structure is simple, easy to operate, and increases practicality.

[0024] Furthermore, this utility model installs a lifting motor 10 and a drive shaft 15 on the base frame 1. The rotation of the lifting motor 10 drives the drive shaft 15 to rotate, and the drive shaft 15 drives the swing arm 14 to achieve lifting and lowering. When the lifting motor 10 rotates, it can drive the swing arm 14 to raise the conveyor frame 8. When the lifting motor 10 rotates for one cycle, the conveyor frame 8 can be lowered. The swing arm 14 connects the double-layer roller 4 with the target workstation or conveyor line with high precision, realizing the purpose of transferring goods laterally to the target workstation or conveyor line. This is convenient, fast, improves the efficiency of conveying, and achieves precise conveying.

[0025] Furthermore, by arranging diffuse reflective photoelectric components 7, proximity switch components 3, side movable components 5, and end face blocking components 6 on or around the conveyor frame 8, this utility model enables precise position detection, flexible guidance and positioning, reliable blocking, and smooth transfer of goods during the conveying process. These components are linked through a PLC or control system to jointly ensure the continuity and stability of goods in the automated logistics process, effectively preventing deviation, jamming, or falling, while improving sorting and docking accuracy and overall efficiency.
