Carefully designed scrap removal systems increase machine efficiency
To get the most from high productivity equipment, manufacturers must move parts and Scrap efficiently and reliably. This makes conveyance equipment an essential consideration. In fact, the right combination of conveyance and feeder equipment can mean the difference between breakdowns and productivity.
In broadest terms, to convey is “to take or carry from one place to another; to transport.” In most metalworking applications, material must be conveyed repeatedly throughout the plant. With the trend toward highercapacity machine tools, the efficient handling of parts and scrap has become increasingly important. Jams or slowdowns in conveyor systems can easily offset machine tool productivity, but a reliable conveyor system that employs the right balance of equipment can promote smooth, uninterrupted production flow.
One of the most important factors in selecting such a system is total cost: initial investment, operating expense, and maintenance requirements. Another important but often overlooked factor is the cost-to-performance ratio per dollar of investment. By balancing all these variables, a manufacturer can design a parts and scrap handling system to improve productivity at a cost that is quickly recovered. While many conveyor systems can and do incorporate standard, off-theshelf components, the nature of the material being conveyed, available floor space, type and performance of production machines, and temperature or other unusual operating conditions determine the ultimate design.
Oscillating and Vibratory Conveyors. Commonly used under the press to carry products or scrap to a less rigid conveyance module, oscillating or vibratory conveyors consist of a metal tray that is supported by directional spring members mounted to a rigid base. Horizontal motion is transmitted to the tray by either a mechanical or electromagnetic drive.
Different tray types are designed to handle a variety of either finished parts or scrap in sizes that range from small stampings or chips to large skeletons. Tray size generally is determined by the size and volume of parts or scrap and the distance the material needs to be conveyed. Diamond-plate trays can be used for handling oily or gummy parts. Tray sizes up to 10 feet wide and 100 ft. long are possible with multiple drive units. Maintenance costs generally are low with these conveyors.
