One function of accumulation conveying is to ensure that goods are allowed to stop and accumulated on the conveyor line without stopping the conveyor drive and without any obvious increase to motor load, to avoid the adverse influence of frequent start-stop on the driving unit. The accumulation can be realized by controlling the operating resistance moment to go beyond or below the work torque by virtue of friction swift.

However, friction coefficient can be easily affected; including the weight of cargos, temperature and humidity, and the uncertain friction may result in the failure of accumulation. Furthermore, the wrong installation or the existence of friction on guardrails will also result in the failure of accumulation in certain areas.

Therefore, Damon 3214/3224 polymer sprocket accumulating roller is recommended for the accumulation conveying of medium & light-load material boxes. Meanwhile, the “intersect layout” solution of arranging conveying rollers (mandatory) across the accumulating rollers can reduce the uncertainty of friction to the largest extent and make the design to be more flexible.

Case I: In the beverage industry, goods are box-packed and film-sealed drinking water, with less weight, usually being 4-7kg (no more than 10kg to the maximum). Considering that box-packed water is conveyed collectively instead of individually, and the bottom surface of film-sealed drinking water is uneven, both of which will dramatically increase the movement resistance during the conveying and result in the failure of accumulation. Therefore, the solution of arranging conveying rollers (mandatory) across the accumulating rollers is put forward to better solve troubles encountered by customers.

Case II: It works well at the very beginning, but two months later, there was a failure of “failing to drive”. The failure can be attributed to the high humidity during the plum rain season, which makes the conveyed boxes to be soften, thus increasing the resistance beyond the expectation. At this moment, even though the “intersect layout” solution is applied, it is also necessary to order new conveyor rollers (mandatory), which may lead to the late delivery of goods to customers regardless of the waste of the replaced accumulation rollers booked at the very beginning. However, Damon 3214/3224 polymer sprocket accumulation roller can achieve the easy switch of “accumulating” and “conveying” by configuring a small part (drive ring), to avoid waste.

In addition, the polymer sprocket roller made by Damon Industry is also featured with the following characteristics:

1. Unique material formula of sprocket gifts such rollers with the capacity of “replacing steel with plastic” and makes it easy to transport goods with the weight no more than 150kg when serving as the conveyor roller, thus meeting requirements of most medium-load container-type conveying.

2. Rust-free property makes it possible to replace stainless steel sprockets and to be applied to slaughtering, fresh distribution, processing of agricultural and sideline products and other work environment and industries featured with water and moisture, thus being more economical.

3. It can be delivered to customers as fast as required due to injection moulding and batch production by virtue of precise moulds.

Damon Industry has been dedicated to improving product quality and property and creating value to customers. We, all Damon workers, have been constantly working for the goal of dedicated design, high-quality manufacturing, forever excellence and consistent quality.
