Conveyor controls have advanced beyond start and stop buttons, with options like reverse, up and down, and alternate path gates. Controls can be activated by human touch, barcodes, and infrared readers. Automatic controls sort packages and adjust conveyor speed. Hand controls adjust tension and alignment, and periodic checks ensure quality. Compressed air is used to remove rejected items, and controls can close the conveyor to allow vehicles to pass.
Conveyor controls go far beyond the simple start and stop buttons used on early models. Reverse, up and down, and alternate path gates are operated by manipulating conveyor controls. While many of the controls are activated by human touch and eye control, some are activated through the use of barcodes and infrared readers. When a package enters a particular section of a conveyor, automatic conveyor controls move the package onto an alternate track to send it to the correct final destination.
Conveyor is a type of roadway that runs through many factories, shops and warehouses around the world. Using the conveyor allows you to produce or send many objects to different places by placing them on the same base tape. Electronic eyes allow a carrier to identify different packages, and through the use of automated carrier controls, the carrier is able to arrange packages into similar groupings. This is also a convenient way to load trucks. These same automatic conveyor controls can slow down or speed up the conveyor to match production.
Some conveyor controls are manipulated by hand. The tension of a belt conveyor and the alignment of a roller conveyor can be adjusted through the use of controls mounted on a central control panel. Gluing, folding and taping are all handled by moving a command to a transport station. Periodic product checks allow workers to make critical changes to controls to ensure quality is not compromised. In some bakery applications, conveyor belt controls trigger and modulate the temperature from cold to hot on some conveyor systems.
Electricity is used for many transportation applications, however, air controls many of the functions along the transportation system. Many rejected items are blown out of the conveyor system by a jet of compressed air. When the computer’s electronic eye detects a problem, the controls call for a blast of air to blow the defective part off the line and transfer it to another conveyor or collection bin. Occasionally, when the conveyor passes a door or other passage, a control will close the conveyor, raise a section of the conveyor to allow a vehicle to pass, then lower and restart the conveyor. The conveyor controls are wired directly into the electronic eyes that activate that application, and the electronic timers dictate how long the conveyor is open once the control is activated.
