Washing & Drying

Rinsing

• After cylindrical brushing, glass then travels to rinsing section where there are water pipes to rinse the glass thoroughly until there are no more residual or contamination on glass surfaces.
• There are access doors. The door could be unlocked and opened for maintenance.
• All parts and components are made of stainless steel or rust-proof materials.

Washing

• This system consists of pairs of cylindrical brushes and water pipes. There are one top brush and one bottom brush for each pair of cylindrical brush. Glass passes in between top and bottom brushes. Top and bottom glass surfaces are thoroughly cleaned.
• Brush filaments are carefully selected such that they leave no marks on glass while strong enough to remove all kinds of dirt, grease and dust, etc.
• There are access doors. The door could be unlocked and opened for maintenance.
• All parts and components are made of stainless steel or rust-proof materials.

General

• Glass washing and drying machine is suitable to wash and dry both top and bottom glass surface. The glass is washed and dried vertically. This vertical design washing machine is in compact design and occupies little space.
• Glass travels vertically at almost 90 degree on washing machine. It always leans against on vertical idle rollers conveyors all the way from the inlet conveyor till exit conveyor.
• There are bottom rollers where glass bottom edge lies on. Bottom rollers drive the glass from inlet conveyor to exit conveyor. All rollers are anti-acid and scratch-free. No marks are left on glass.
• It is very easy to operate and it is maintenance friendly.

Air Blower

• An air blower is located behind washing machine. It is enclosed inside a sound-proof box for acoustic purpose. The air blower generates appropriate quantity of air at proper air pressure.
• The air flows through air ducts and arrives at air knives. There are filters to ensure inlet air blown on glass is clean and free of contamination on glass.

Drying

• After glass leaves rinsing section, it immediately enters into drying section. Pairs of air knives are put vertically and are inclined at certain angle to glass travel direction.
• There are narrow openings on each of air knives. Drying air with optimum quantity and pressure is blown on front and rear glass surface. The water is thoroughly dried.

Water Recirculation

• Water is pumped from stainless steel water tank and is then spray on brushes through water pipes with sprinkle. The water is evenly distributed on brushes and is spread on glass thoroughly. Water drips down to water tank by means of water collectors.
• There are water filters to keep water clean so that pipes and nozzles are unblocked.
• Thermostat and heaters are available to keep water warm or hot at constant temperature.

Inspection

After glass leaves drying section, it exits on this inspection conveyor. This rollers conveyor is similar to inlet conveyor but with additional fluorescent lamps located at the back of glass. This is used to inspect if glass is clean enough for double glazing.

Positioning & Assembly

• It is a conveyor structure which is longer enough to park two glass panes. When glass passes inspection, it travels till the end of this section and stops automatically.
• At the end of this conveyor right before panel press, there is a spacer frame positioning system which helps operator to put spacer frames in correct position on glass surface. This system is composed of two bars, one vertical and one horizontal. There are several stoppers on each bar. Each stopper is extendable and can be locked by screw. Vertical bar situates right before panel press entrance. Horizontal bar is at conveyor bottom. Stoppers are adjusted and extended over glass leading and bottom edges until requested distance between spacer frame and glass edges are obtained. This distance is the space that will be filled up by secondary sealant. Stoppers are locked in position. Operator loads spacer frame on glass with leading edge against vertical stoppers while bottom glass edge against horizontal bar. While frame is hold in correct position, operator pre-adhere spacer frame on glass by means of butyl sealant.
• Meanwhile, subsequent glass is washed, dried, inspected and enters into this section until it arrives next to first glass. Subsequent glass is then put on first glass separated by well-assembled butyl coated spacer frame. Leading edges of two glass panes are in exact positions.
• If triple or multiple glazing is required, cycle is repeated. When multi-insulated glass is well assembled, it travels to subsequent rollers press.

Rollers Pressing

• It consists of one pair of vertical rollers. Rotary rear roll is driven by motor. Front roll is idle and freely rotates. It can be moved towards or away from steady rear roll by pneumatic. This is to adjust rollers space according to double glazing thickness. Rollers are covered with carefully selected rubber which provides sufficient hardness to seal glass and meanwhile, enough softness not to break glass.
• Well-assembled insulated glass begins to travel from assembly conveyor towards rollers press. When it arrives at rollers entrance, rotary rear roll takes the glass in between rollers. After rollers press along glass edges all the way, glass primary sealed is well done.
• Roller rotating is carefully design such that it ensures consistent rollers rotation. Pressing air pressure is adjustable. It is also design in such a way that leading and tail glass edges are hold with time delay, which in other words, allowing more time to press at edges. This design guarantees uniform pressure acting all the way along glass edges. It results in thoroughly primary sealed.

Exit

Exit section structure is similar to inlet section. After pressing and sealing, glass exits to this section and is finally inspected. Semi-finished insulated glass is ready unloaded for subsequent secondary or final seal.

General

Driven Mechanism

Bottom rollers from inlet conveyor till outlet conveyor are all steadily driven electrically by reliable motors with infinite gearbox with the aid of clutches. Each section could be individually driven when clutches release. Top quality parts and components guarantee consistent movement of all rollers.

Control

This free stand alone cabinet is used to control all motors and conveyor speed, etc. With a PLC system, all operations are accessed from this control panel. Glass movement and press rolls are controlled by infinite speed frequency converter and photosensors.

Photosensors

There are several photo-sensors to control sequent logically of glass travel and stop, and press rolls as well.

• After inspection, glass passes the first photo switch and travels all the way to the end of assembly conveyor until it hits the third photo switch. Glass is now in front of positioning stoppers prior to press rolls.
• Meanwhile, subsequent glass travels and stops at second photosensor after washed and dried.
• After first glass is lay with spacer frame, subsequent glass is moved for assembly with first glass. This releases the second photosensors, which allows third glass traveling from inlet conveyor to washing machine.
• Well assembled insulated glass (first and second glass) now leaves third photoseonsor and travels in between press rolls. When it hits the forth photo switch, it activates time delay system of PLC. It ensures glass leading and tail edges are hold by press rolls with more time.
• When glass travels and leaves the forth photo switch, the sensor is activated to instruct glass stops in exit section.
