Automatic chain-on-edge system

Description

This machine is designed for spray coating of cylindrical workpieces.

The system is integrated in and mounted on sectional steel frames. The chain cover in the operating and coating zone is made of stainless steel. Transport chain drive is via a variable gear unit with an explosion-protected variable-speed gear motor. The cycle speed is adjustable from 2 to 20 cycles per minute, equivalent to a maximum machine output of 1,200 parts per hour.

The transport chain is supported in a guide rail, and a 1 inch roller chain prevents undesired polygon effects. Chain tension is effected automatically by a pneumatic cylinder. Three spindles at the coating point are variable controlled in a range from approx. 40 to 400 rpm via a control gear with explosion-protected threephase motor. The rotary motion is transferred via air-cushioned pressure rollers. A lifting device to hold the spray guns can be installed at the coating point. The linear lifting stroke also permits vertical spraying motions with one or more guns.

The lifting speed can be separately adjusted for forward and reverse motion. An electronic path recording unit permits customised programming of traversing paths within the range of the stroke.

Dry exhaust-extraction is performed using a moveable filter trolley in which labyrinth baffle filters with downstream fibre glass fine filters are installed. Additional fibre glass fine filters can be fitted in front of the main filter system. The filters are monitored by differential pressure needle pressure gauges with changing point display. There is an encapsulated ventilation zone behind the coating zone. Supply air feed is via an explosion-protected fan.

Two adjustable spraying times and spraying pressures can be set at the spraying point, and up to three spray guns can be connected in each case via rapid-fix couplings.

The spraying time is set via pushbuttons with digital time display. The spray guns connected to the lifting device are controlled in dependence on the lifting motion and the set lifting range. The system can be tailored to suit specific customer needs at any time; there is also a retrofit option for a chain extensions or a mounted drier.
