Description

Technical Field

[0001] This utility model relates to the field of automated production technology of octagonal tubes, specifically to a device for storing and transferring tubes. Background Technology

[0002] With the widespread adoption of Industry 4.0 in the automotive manufacturing sector, the combination of flexible octagonal tube grippers and industrial robots has gradually replaced manual labor, and is widely used in core automotive production line processes such as gluing, welding, and material handling. As a key component of flexible grippers, the market demand for octagonal tubes has increased significantly, driving the transformation of octagonal tube production from traditional manual to automated methods. During this transformation, automated production lines place higher demands on supporting equipment, especially requiring storage and conveying equipment that can adapt to the characteristics of octagonal tube profiles to ensure the continuity and efficiency of the entire production process. However, existing equipment cannot yet meet this core requirement.

[0003] Current pipe storage and conveying equipment on the market generally suffers from limited storage capacity, insufficient operational accuracy, and low automation levels, making it difficult to match the operational rhythm and precision requirements of automated octagonal tube production lines. Such equipment not only fails to achieve large-scale, orderly storage of octagonal tubes but also easily affects subsequent processing steps due to positioning deviations during conveying, leading to decreased production efficiency and unstable product quality. Therefore, developing a dedicated storage and conveying device for octagonal tube products, addressing the shortcomings of existing equipment in terms of storage capacity, accuracy, and intelligence, is crucial for promoting the implementation of automated octagonal tube production and improving the overall efficiency of the production line. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a device for storing and transferring pipe materials. This device solves the technical problems in the field of automated production technology of octagonal tubes, where existing storage and conveying equipment cannot meet the storage capacity, operating accuracy and intelligent requirements of octagonal tube profiles, and is difficult to adapt to the operation rhythm and accuracy requirements of automated production lines for octagonal tubes, resulting in low production efficiency and unstable product quality.

[0005] To achieve the above-mentioned technical objectives, the present invention provides a device for storing and transferring pipes, including... Two pipe transfer mechanisms are arranged vertically opposite each other. Each pipe transfer mechanism includes a conveying base plate, a single-row guide rail, a conveying slider, a transmission slider, and a first transmission rotary body. Six sets of single-row guide rails are provided, including two sets of long-side guide rails and four sets of short-side guide rails. The short-side guide rails are ring-shaped. The long-side guide rails and short-side guide rails are connected end-to-end, with the two sets of long-side guide rails parallel to each other and the four sets of short-side guide rails symmetrical about the central axis of the base plate, forming a closed ring-shaped guide rail. Multiple first auxiliary pulleys are provided at each of the four corners of the closed guide rail. Each first auxiliary pulley is located between two adjacent single-row guide rails at the corresponding corner. The first auxiliary pulleys are rotatably connected to a fixed base via a rotating shaft, wherein the fixed base is fixedly connected to the conveying base plate.

[0006] Compared with the prior art, the beneficial effects of this utility model include: Integrated storage and conveying improves production efficiency: Drive chains are set at the bottom and top of the device, and with multiple independent storage locations, the device can store multiple tubes. While realizing large-scale orderly storage of octagonal tubes, the conveying operation is completed through the transfer drive source control. The storage function and transportation function are organically combined. No additional equipment is needed for transfer, which greatly shortens the circulation time of octagonal tubes in the production process and improves the overall production efficiency.
