The layout optimization of the friction roller conveyor line is crucial to improving the efficiency and safety of cargo transportation, which requires full consideration of the characteristics of the cargo.
First, the layout should be different for cargo of different shapes and sizes. If the cargo is a regular rectangular block with a large size, the roller spacing can be appropriately widened to ensure that the cargo is placed stably and does not cause unnecessary bumps or jams due to the over-dense rollers. For example, when conveying large household appliances, a wider roller spacing can better bear the weight of the cargo and keep it moving forward steadily. For small, irregularly shaped cargo, such as parts, the roller spacing needs to be reduced, and even a special segmented roller layout can be used to add auxiliary support rollers at key locations to prevent the cargo from falling or deviating from the conveying track due to excessive gaps during transportation.
Secondly, the weight of the cargo is also a key factor. For heavier cargo, friction rollers with strong load-bearing capacity should be selected, and the number of rollers should be increased in the layout to disperse the weight of the cargo and reduce the load of a single roller. At the same time, at the starting end and turning points of the conveyor line, the arrangement density and fixing method of the rollers should be strengthened to ensure that the goods can transition smoothly when starting and turning, and avoid deformation of the rollers or damage to the conveyor line structure due to excessive weight. For example, in the conveyor line for conveying heavy machinery parts, the roller layout at the starting end will be tighter and a more solid installation structure will be used.
In addition, consider the surface material and friction characteristics of the goods. If the surface of the goods is smooth and the friction is small, the roughness of the roller surface should be appropriately increased, and some auxiliary friction increasing devices such as rubber pads or anti-slip strips can be set in the layout to ensure that the goods can be stably transported on the rollers. On the contrary, if the surface of the goods is rough and easily damaged, the rollers need to be made of smoother and softer materials, and the slope and turning radius of the conveyor line should be reasonably planned to reduce friction and collision between the goods and the rollers. When conveying fragile goods such as glass products, special low-friction, high-elasticity roller materials are used, and the conveyor line is carefully designed to avoid sharp turns and slope changes.
Finally, according to the conveying flow and frequency of the goods, optimize the branching and merging layout of the conveyor line. If the cargo flow is large and the types are many, multiple parallel conveying branches can be set up to classify and convey the cargo according to the destination or subsequent processing link to improve the overall conveying efficiency. At the branch and merging nodes, precise guide devices and sensor control are used to ensure that the cargo enters the corresponding conveying path accurately and avoids confusion and blockage, thus achieving an efficient, safe and cargo-adapted friction roller conveyor line layout.
