Description

Technical Field

[0001] The utility model relates to the technical field of accumulation roller conveyors, in particular to a side friction accumulation roller conveyor. Background Art

[0002] The accumulation roller conveyor is an important conveying equipment. It conveys items by the rotation of the roller. It also has an accumulation function, which allows items to stay and accumulate at a specific location. Its characteristics include high conveying efficiency, smooth operation, and strong carrying capacity. The conveying speed and accumulation quantity can be flexibly adjusted according to different production needs. For example, on an automobile production line, parts can be accurately transported to each workstation. When a workstation needs to pause, the parts can be accumulated on the conveyor and wait. In logistics warehousing, goods can also be effectively classified and temporarily stored. Accumulation roller conveyors are widely used in various industries, greatly improving the level of automation in production and logistics.

It is small, and the daily maintenance workload is small. When conveying aluminum alloy cylinder parts, the precision machining surface of the aluminum alloy cylinder body will not be damaged, so it can well adapt to the workpiece conveying needs of the machining line of the aluminum alloy cylinder body, and solve the problem that most of the existing accumulation roller conveying systems adopt the form of built-in bearings. The accumulation roller conveying system using the built-in bearing form cannot meet the flexible needs of aluminum alloy cylinder conveying throughout the process, and is restricted by the structural form and machining accuracy of the built-in bearings. Its radial runout is large, the accumulation torque is not adjustable, and the precision machining surface of the aluminum alloy cylinder body is often damaged when conveying aluminum alloy cylinder parts, affecting product quality.

[0004] In the process of using the accumulation roller conveyor, there are existing accumulation roller conveyors such as the above-mentioned ones, whose side covers are mostly inserted into the installation position from the side. During the maintenance of the equipment, the staff must pull out the side cover from the side. Due to the long length of the side cover, the staff needs to pull the side cover and walk a long distance when performing the disassembly operation, which increases the disassembly burden of the staff and affects the maintenance efficiency.
