Description

Technical Field

[0001] This application relates to a four-way conveying device for ring conveying, belonging to the field of automated warehousing and logistics technology. Background Technology

[0002] With rising land and labor costs, the concept of high-density warehousing is attracting increasing attention from logistics and e-commerce companies. Automated storage and retrieval systems (AS / RS), due to their high space utilization and strong inbound / outbound capabilities, have become an indispensable warehousing technology for enterprise logistics and production management, with their application in industries such as automotive, chemical, electronics, and tobacco growing year by year. In the coming years, one of the technological development trends of automated storage and retrieval systems will be high speed, high efficiency, and high density.

[0003] Circular conveyor systems are a common type of conveyor at the front end of automated storage and retrieval systems (AS / RS). Currently, four-way shuttles are commonly used for material transport. These shuttles utilize a grid-like track, and the shuttles travel sequentially along the track. In the loading and unloading area, because materials need to be loaded and unloaded in a fixed direction, the four-way shuttles require reversing tracks to change direction and adjust the loading / unloading orientation. Furthermore, existing four-way shuttles require material transfer mechanisms to load and unload materials onto the shuttles, resulting in low material transport efficiency and high operating costs. Therefore, a new conveying system is needed to address the problems of low material transport efficiency and high operating costs associated with using four-way shuttles for circular material transport, where materials need to be moved in a fixed direction.

[0026] Please see Figure 1-4 This embodiment provides a four-way conveying device for looping, including a four-way shuttle 7 and a conveying assembly 8. The conveying assembly includes a platform 9, a drive unit, and a conveying unit. The platform 9 is rotatably mounted on the frame 1 of the four-way shuttle, and one end of it is connected to the power end of the drive unit. The conveying unit is mounted on the platform for moving goods out of or into the platform. The conveying unit in this embodiment includes two conveying chains 10 and a conveying motor 11. Drive wheels are rotatably mounted at the four corners of the platform 9. The two conveying chains are relatively parallel and rotatably sleeved on the outside of the two drive wheels on the same side of the platform. A connecting shaft 12 connects the drive wheels on opposite sides of the platform, and a connecting wheel 13 is mounted on the connecting shaft. The conveying motor is fixedly mounted on the platform, and its power end has an output wheel 14. A connecting chain (not shown) is sleeved between the connecting wheel and the output wheel. Furthermore, the drive wheel, connecting wheel, and output wheel in this embodiment are all sprocket structures.

[0027] The four-way shuttle of this application includes a frame 1 and a lifting mechanism 2 and a traveling mechanism 3 disposed within the frame. Traveling wheels are installed around the frame. The traveling wheels are divided into main channel traveling wheels 5 and secondary channel traveling wheels 6 according to their installation direction on the frame. The main channel traveling wheels travel along a track in a first direction, and the secondary channel traveling wheels travel along a track in a second direction, with the first and second directions perpendicular to each other. The traveling mechanism of this embodiment includes a transmission assembly and a drive assembly. The main channel traveling wheels 5 are symmetrically arranged on both sides of the frame in the main channel running direction (i.e., the first direction), and the secondary channel traveling wheels 6 are symmetrically arranged on both sides of the frame in the secondary channel running direction (i.e., the second direction). The main channel traveling wheels and the secondary channel traveling wheels are connected to the drive assembly via the transmission assembly 50.

[0028] Furthermore, the transmission assembly 50 of this embodiment includes two spatially intersecting first transmission shafts 51 and second transmission shafts 61. The first transmission shafts 51 and second transmission shafts 61 are connected by a drive assembly to drive the traveling wheels around the frame. In this embodiment, the main channel traveling wheel 5 is driven to the first transmission shaft 51, and the secondary channel traveling wheel 6 is driven to the second transmission shaft 61. The second transmission shaft 61 is slidably mounted on the frame through a lifting mechanism to switch the traveling direction of the traveling wheels.

[0029] The main channel traveling wheel 5 in this embodiment includes two pairs of active main channel wheels 500 and two pairs of driven main channel wheels 501. The active main channel wheels 500 and driven main channel wheels 501 are arranged opposite to each other on both sides of the frame. The two pairs of active main channel wheels 500 are connected to the first drive shaft 51 through the first sprocket pair 52. In this embodiment, the lifting mechanism 2 consists of two sets of chain lifting units installed in the frame. Each set of chain lifting units controls the lifting of the auxiliary channel traveling wheel on one side. Each set of chain lifting units includes two lifting reduction motors 200, a lifting transmission shaft 201, a rigid chain transmission pair 203 (chain not shown), and two chain lifters 202. The two chain lifters 202 installed on the same side of the frame are connected to the lifting transmission shaft through a coupling. The lifting transmission shaft 201 is driven by the rigid chain transmission pair 203 and the lifting reduction motor 200. The top output shaft of the chain lifter 202 drives the lifting plate 204. One end of the lifting plate extends horizontally outward from the frame to form an extension end. A sliding block 205 is fixedly installed at the bottom of the extension end. The sliding block is slidably installed on the frame in the radial direction, and the auxiliary channel traveling wheel is rotatably installed on the sliding block 205. In this embodiment, the auxiliary channel traveling wheel 6 includes two pairs of active auxiliary channel wheels 600 and two pairs of driven auxiliary channel wheels 601. On the sliding blocks of the two chain lifts on the same side of the frame, a pair of active auxiliary channel wheels and a pair of driven auxiliary channel wheels are rotatably mounted respectively. A second drive shaft 61 is installed between the sliding blocks where the two pairs of active auxiliary channel wheels are located. The two pairs of active auxiliary channel wheels are connected to the second drive shaft through the second sprocket pair 53.

[0030] In addition, the drive assembly of this embodiment includes a walking motor 300 and a dual-output shaft reducer 301. The two sets of output shafts of the dual-output shaft reducer 301 are respectively connected to the first drive shaft 51 and the second drive shaft 61 through the third sprocket pair 54 and the fourth sprocket pair 55.

[0031] The driving component in this embodiment includes a bearing and a power component. The bearing is a slewing bearing 15, with its outer ring fixedly mounted to the frame and its inner ring fixedly connected to the platform. The inner ring of the slewing bearing is provided with an internal gear ring. The power component in this embodiment is fixedly mounted to the frame and includes a rotary motor 16 and a reducer 17. The power output end of the rotary motor is connected to the power input end of the reducer, and a drive gear 18 is mounted on the power output end of the reducer, meshing with the internal gear ring gear.

[0032] Furthermore, guide wheels 19 are rotatably mounted on the four corners of the shelf in this embodiment. At the same time, material limiting plates 20 are fixedly mounted on both sides of the shelf, and the two ends of the material limiting plates are bent outward to form guide portions.

[0033] Working Principle: In this embodiment, when the four-way shuttle of the ring-through conveyor moves from the secondary aisle to the main aisle along the gridded track, the lifting mechanism starts operating, and the sliding plate on the side of the secondary aisle's traveling wheels moves up. The ring-through four-way conveyor is now facing the main aisle, and the main aisle's traveling wheels contact the main aisle track, allowing the ring-through four-way conveyor to travel on the main aisle. Functions at this time include: running on the main aisle, carrying goods on the main aisle, and entering the loading and unloading area for material loading and unloading.

[0034] When the four-way conveyor enters the loading / unloading area from the main channel, assuming material needs to be loaded, the rotary motor starts to drive the platform to rotate, adjusting its conveying direction to align with the material loading direction. The four-way conveyor then continues along the track to the loading station. The conveyor chain on the platform connects with the conveyor belt in the loading area, and the material is driven to the platform by the chain. During this transfer, material limiting rods on both sides of the platform limit and guide the material to complete loading. The four-way conveyor then moves along the track towards the material unloading station.

[0035] During the transfer process, when the four-way conveyor moves from the main channel to the secondary channel and needs to enter the secondary channel, the four-way shuttle at the bottom stops. At this time, the lifting mechanism starts, and the driving force of the lifting reduction motor is transmitted to the lifting drive shaft through the rigid chain transmission pair, which in turn drives the chain lift to move the sliding plate down the frame. As the sliding plate moves down, it causes the secondary channel traveling wheels to contact the secondary channel track. The sliding plate continues to move down until the secondary channel traveling wheels are fully in contact with the track, while the main channel traveling wheels leave the track. At this time, the secondary channel traveling wheels run, and the four-way conveyor moves the material to the secondary channel track according to the scheduling requirements, until it is transferred to the material loading and unloading station.

[0036] When the four-way conveyor reaches the material unloading station, it adjusts its unloading direction based on the material unloading direction of the loading platform. If the unloading direction of the loading platform matches the conveyor belt direction of the unloading station, no adjustment is needed. Otherwise, the rotary motor is activated to drive the loading platform to rotate and adjust its unloading direction. The four-way conveyor then continues along the track to the unloading station. The conveyor chain on the loading platform connects with the conveyor belt at the unloading station, and the material is moved via the conveyor chain to the conveyor belt at the unloading station to complete the unloading. This process repeats automatically, allowing the four-way conveyor to load and transport materials.

For those skilled in the art, after learning the contents recorded in this application, several equivalent changes and substitutions can be made without departing from the principle of this application.
