Rotary turntables play an important role in the automation and profitability of the filling process. At higher rates of production, many automated machines only work at peak efficiency when bottles are moved along via a conveyor belt while also being lined up side-to-side with no gaps. For example, a piston filler with multiple heads would miss the bottles that had to be filled and were not positioned precisely. This same careful positioning is also needed for any machine that is designed to handle more than one bottle at a time.
Without a loading rotary turntable, an individual worker would need to constantly load up a long-enough backlog onto the conveyor belt to maintain a steady feed of bottles through whatever machine is being used – such as a filler, capper or labeler. In addition, the bottles would have to be spaced neatly by hand, which would further slow down production. With a loading rotary turntable in place, however, one person can add a large number of containers to the turntable at once and allow the machine to move them evenly onto the conveyor belt. That person can then work on other things in-between reloading the turntable.
Accumulating rotary turntables safely gather up the bottles once they have passed through the machine. Without them, production would have to be stopped frequently before the containers reached the end of the conveyor belt, especially if they are made of fragile materials. The rotating table can also collect many bottles streaming in without the risk of them bunching up and tipping over, as may happen if the conveyor belt ended at a non-rotating tabletop. As the accumulating rotary turntable starts to fill up, the bottles can be removed and packaged while more containers continue to be processed.
Both types of turntables feature stainless steel guide rails and variable speed motors, and they can process up to 150 containers per minute.
Loading the Containers
When the bottles are placed on the loading rotary turntable, the steady rotation of the surface brings them into contact with either the guide rail along the outer edge, or the flexible bottle guide that extends from the center of the disk to nearly the outer edge, forming a narrowing angle. When a batch of containers is too large to fit through the gap between the guide and the rail, the extra bottles either travel around the inner portion of the disc until they are guided by the strip again, or the bottles slightly widen the gap as they pass through it. With repeated rotations, the bottles are soon lined up neatly along the outer edge of the turntable, ready to be moved onto the conveyor belt in single file.
Accumulating Containers at the End of the Line
The process is echoed at the end of the production line as the containers make their way to the accumulating rotary turntable. When the bottles leave the conveyor belt, they pass onto the turntable in a smooth line that goes around the outer edge, held in by the rails. As more bottles come onto the turntable, the movement and the guides work together to move the bottles closer to the center until most of the surface area is filled and the bottles can be removed for packaging or for another stage of the filling process.
These turntables can be an end point of the filling process, or they can hold containers that are being conveyed between two different stages of packaging.
Turntables are used in the production of cosmetics, food and beverages, cleaning and specialty chemicals, pharmaceuticals, personal care and more.
