Timing screws are adjustable screws otherwise referred to as screws, helices or worms. Timing screws are used in virtually every application in the packaging line operations. The timing screw is straight and has threads such that while running its thread pitch is frequent but not as uniform as in fastening screws. Additionally, the timing screws function by rotating which complements its various designs such as the straight root design, Inverse taper design, shingle in-feed design, and the non-round choke design. Timing screws are used to meter containers during production onto the star wheel that has a capper or onto other machines which will end up in the final packaged product. Timing screws have special functions in which they articulate effectively and accurately. Some of these functions include;
Turning timing screws
Timing screws with the packaging line or conveyor system assist in turning the containers in the production process to specific angles such as 900, 1800 and 3600. This way the containers can take up the proper orientation as intended in the production line. Essentially, to turn a container, the system requires two timing screws.
Dividing timing screws
The timing screws are used to create a consistent arrangement on the packaging line. This is achieved by dividing containers that are conveyed in a single lane into two or three lanes. The dividing of the containers is attained through the use of a matching pair of timing screws that adjust the containers to operate within a gapping of as little as 24 inches.
Dwell timing screws
Timing screws within the packaging line ensure that the line is continuously supplied by containers. This ensures that containers are fed into the production or packaging line which assists in intermittent packaging operations that involve filling, capping as well as cottoning for movement and storage. The dwell timing screw uses a screw thread that is automated to allow the container to stop from its forward thrust or motion such that it can take the revolutions needed for the above procedures to take place.
Combining timing screws
Within the production line, the process is combined in different phases. This way it is possible for the containers to proceed to various machines and eventually end up as the final packaged output.
Transfer timing screws
Essentially, the timing screws control the movement of the containers as they move within the production line or from one machine to the other. Therefore, the timing screws facilitate the transfer that occurs in precise transfer patterns. Moreover, it achieves similar pocket configurations that enable the packaging line to handle a wide variety of containers.
