The block accumulation type conveying is similar to the speed chain accumulation, when the workpiece needs to be assembled or needs to be stopped, the workpiece is blocked by the block under the action of electric driving of the gears as long as the switch of the corresponding station is pressed, and the work is finished; the stop block moves downwards, and the workpiece is released, so that the accumulation effect can be realized. The stop blocks are stacked, the shape of a common workpiece is regular, the part which realizes sliding friction with the roller needs to be smooth, and the stop blocks are generally used for conveying parts with light weight. Stage-directed stacking transport refers to staged transport where a workpiece is moved onto a first conveyor roller line and the trailing end of the workpiece encounters a sensor to stop transport, and when the next workpiece arrives, the conveyor is again activated to move until the trailing end of the workpiece is completely on the conveyor roller, which continues until the first workpiece reaches the end of the conveyor, and then a sensor indicates that a full row of workpieces is on the first conveyor and the row of workpieces is moved completely to the furthest empty conveyor. The workpieces can be removed from the release end of the accumulation line, so that one workpiece or a whole row of workpieces can be removed at a time, and when the conveyor at the release end is completely empty, a row of workpieces on the previous conveyor can be fed in. Therefore, the accumulation effect is achieved, but the accumulation mode has the defects of higher cost and short service life of the motor of the over-frequency starting motor.
The accumulation roller is an important component of an accumulation roller type conveying line, the accumulation function of the existing accumulation roller is realized by adopting an axial asbestos-based friction plate and spring pressing structure, the accumulation roller with the structure is complex in structure and high in cost, and the asbestos-based friction plate is not environment-friendly in use.
