![]() P&F conveyors also move continuously on a chain-driven system and, like monorails, are extremely durable, but they can be much costlier. ![]() Changing the system to move faster or slower–for example, if you need to shorten the cure time for a new paint-means all other processes on the line will occur faster as well, from loading to pretreatment to cool-off. Stopping part of the line for any unscheduled process or other reason stops the entire line upstream and downstream as well. Monorail conveyors typically move at a slow pace and continuously. A “caterpillar drive” or sprocket drives the chain from the drive unit, and a take-up unit ensures the chain is pulled tight as it leaves the drive unit to complete its circuit. The chain is typically guided by a rail system based on I-beams or enclosed tracks. The load-carrying and drive functions of monorail systems are combined in one element: an “endless chain.” These systems are typically the least expensive automated option, and they are known for being extremely durable. Each has its advantages and disadvantages no conveyor type is perfect for every application. These three are monorail, power and free, and friction-driven conveyors. In automated powder finishing systems, there are three primary types of conveyors all three are usually installed overhead, although each can also be installed at other elevations, depending on the process. Facilitate the implementation of an accurate part finishing recipe, or recipes if there are variations.Relay system data and sometimes process and part data to operators and managers, usually through integrated computer controls, and sometimes connection to existing enterprise resource planning (ERP) systems and functions.Move parts to and from point-of-use stations.Minimize wasted movement and damage to parts, as well as risk of injury.Move parts efficiently between and through processes.Perhaps answering these questions will lead you to consider systems that are expandable for future growth, flexible to incorporate new technologies, adaptable for changes in processes and able to convey to point of use (from fabrication to finishing to shipping).įor the most part, systems start with deciding on the fourth consideration: the most appropriate method of conveying parts. Should cart or fork truck transfer be eliminated by using the same overhead conveyor to deliver parts to the paint system from welding and/or then to shipping?.Will the current processes remain the same? Will continuous improvements allow for new part designs that no longer require masking? Powder instead of liquid? Two-coat powder?.Are there likely to be vast advancements in any aspect of what is being done currently, such as new pretreatment technology, new coating technology or new curing technology?.How many parts will need to be painted per hour, now and 10 to 15 years from now?.
