Technical Field

[0001] This utility model relates to the technical field of logistics and warehousing, and more specifically to a friction extraction mechanism and a roller conveyor. Background Technology

[0002] With the rapid development of the logistics industry, higher demands are being placed on the storage capacity and retrieval efficiency of logistics warehousing. Traditional warehouses are struggling to meet these requirements, leading to the widespread adoption of automated storage and retrieval systems (AS / RS) with larger storage capacity and higher retrieval efficiency. AS / RS generally refers to warehouses that use racks with several, dozens, or even hundreds of layers high to store goods, employing corresponding material handling equipment for storage and retrieval. AS / RS can fully utilize space for storing goods and can automatically and efficiently complete goods storage and retrieval, thus effectively connecting external production processes and forming an automated logistics system centered around the warehouse. Therefore, improving the retrieval performance of AS / RS is crucial for enhancing the overall efficiency of the logistics system.

[0003] Existing automated storage and retrieval systems (AS / RS) typically use stacker cranes in conjunction with racks to retrieve and place goods. However, to effectively retrieve and place goods, each rack location requires a drive mechanism. Large-capacity AS / RS require a large number of drive mechanisms, resulting in high costs and complex maintenance. Furthermore, existing drive mechanisms are generally unsuitable for heavy-duty applications.

[0004] In summary, there is a need in this field for a drive solution that can complete the picking and placing of goods through a single drive structure and can achieve heavy-duty drive, so as to reduce costs while meeting the needs of logistics and warehousing. Utility Model Content

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.

[0023] like Figure 1 and Figure 2As shown, this application discloses a friction extraction mechanism that is combined with a roller conveyor. The telescopic friction extraction mechanism includes a telescopic drive motor 1, a transmission belt 2, and a friction wheel assembly 3. The telescopic drive motor 1 drives the friction wheel assembly 3 to extend or retract through the transmission belt 2. When the friction wheel assembly 3 is in the extended state, the friction wheel assembly 3 contacts the drive roller of the roller conveyor and the shelf roller simultaneously. The drive roller is driven by the friction wheel assembly 3 to make the shelf roller rotate in the same direction, thereby realizing the storage or retrieval function.

[0024] Specifically, the telescopic drive motor 1 is installed in conjunction with the drive motor mounting plate 10, and is also installed in conjunction with the roller conveyor via the drive motor mounting plate 10. Preferably, the top of the drive motor mounting plate 10 is connected to the roller conveyor, and the telescopic drive motor 1 is installed on the side of the drive motor mounting plate 10. During maintenance and replacement, the drive motor mounting plate 10 and the telescopic drive motor 1 can be removed together from the top of the roller conveyor, making the operating angle more comfortable and maintenance and replacement more convenient and quick.

[0025] The output end of the telescopic drive motor 1 is equipped with a double-row drive sprocket 11, and the transmission belt 2 is a double-row chain. One end of the transmission belt 2 is wrapped around the double-row drive sprocket 11, and the other end is wrapped around the double-row driven sprocket 21. The double-row driven sprocket 21 is connected to the friction wheel assembly 3 for transmission. By setting the transmission structure of double-row sprockets and double-row chains, more stable transmission performance and higher load capacity can be provided.

[0026] The friction wheel assembly 3 includes a friction mounting plate 30, an extraction telescopic arm 31, and a set of friction wheels 32. One end of the extraction telescopic arm 31 is rotatably connected to the friction mounting plate 30, and the other end of the extraction telescopic arm 31 is fitted with the friction wheels 32. The friction mounting plate 30 is installed in conjunction with the roller conveyor. A double-row driven sprocket 21 is connected to the extraction telescopic arm 31 for transmission. The telescopic drive motor 1 drives the extraction telescopic arm 31 to extend or retract via a transmission belt 2, driving the friction wheels 32 to simultaneously contact or de-contact with the drive rollers and shelf rollers of the roller conveyor. Preferably, the outer ring of the friction wheels 32 is made of organic material to increase friction while reducing rigid friction, thereby extending the service life of the rollers and friction wheels 32. Furthermore, the friction torque design of the friction wheels 32 with the drive rollers and shelf rollers of the roller conveyor meets the requirements for synchronous normal operation of 6.8t of goods, and the linear speed of the friction wheels is not less than 18m / min, meeting the requirements for high-efficiency transportation with heavy loads.

[0027] like Figure 3As shown, this application discloses a roller conveyor comprising a support 4, a plurality of conveying rollers 51 and anti-slip tracks 50, a friction drive assembly, and two sets of the aforementioned friction extraction mechanisms. The conveying rollers 51 and anti-slip tracks 50 are installed on the support 4 at intervals and parallel to each other. All conveying rollers 51 are driven synchronously by the same drive device. Friction drive assemblies are respectively installed at both ends of the support 4, and the friction drive assemblies are respectively installed at the bottom of both ends of the support 4. When picking up or placing goods, the friction wheel assembly 3 of the friction extraction mechanism extends and simultaneously contacts the friction drive assembly and the shelf rollers. The friction drive assembly drives the shelf rollers and conveying rollers 51 to rotate synchronously through the friction wheel assembly 3, thereby realizing the picking up and placing of goods. The anti-slip tracks 50 are full-width anti-slip tracks, easy to disassemble and replace, and the use of anti-slip tracks 50 facilitates the reduction of maintenance and repair of the roller conveyor. A failure in one set of the two sets of friction extraction mechanisms does not affect the normal operation of the other set, and a failure in a single friction extraction mechanism within a set does not affect the normal operation of the other friction extraction mechanism, providing redundancy in the event of a sudden failure and resulting in higher overall efficiency.

[0028] Adjacent conveyor rollers 51 are connected in pairs via chains 53 for transmission. One pair of conveyor rollers 51 is connected to a drive motor via a drive chain 52. A single drive motor drives all conveyor rollers 51 to rotate in the same direction and synchronously. Preferably, both chains 53 and drive chains 52 are double-row chains, and both ends of the conveyor rollers 51 are connected to chains 53 or drive chains 52 via double-row sprockets to ensure transmission performance and operational stability. Preferably, the bearings of the conveyor rollers 51 have a sealed structure, providing dustproof and permanent lubrication characteristics, allowing for long-term use without replacement.

[0029] The preferred support 4 has guide ramps on the inner side of both ends of the roller conveyor to facilitate the input and output of goods and improve the fault tolerance rate of picking up and placing goods.

[0030] The friction drive assembly includes a friction drive motor 61 fixedly connected to the bracket 4 and a drive roller 62 rotatably connected to the bracket 4. The drive roller 62 is installed at both ends of the bracket located on the roller conveyor. The friction wheel assembly 3 is connected to the drive roller 62.
