Machine Introduction

Glass measuring table

Drive system

The equipment is used to transfer and position the glass to be processed, make an accurate measurement of length, width and thickness of the glass, and transmit the data to double-edge grinder and other processing equipment for further glass processing.

The construction of glass measuring table includes 4 parts as below:

1. Positiong table

The transmission of glass moving to front or to side is driven by frequency converter and variable frequency motor. The transmission speed can be adjusted. Precise positioning by high-quality sensors. Length, width and thickness of the glass could be measured after proper positioning.

 

2. Measuring device

The dimension of glass length and width is measured by highly precisive gear drive sensor driven by servo motor. The dimension of glass thickness is measured by cylinder driven nylon block pressuring on the glass surface and encoder driven by gear. The cylinder pressure is adjusted separately.

 

3. Electrical control system

ECS consists of programmable controller (PLC), touch screen (HMI), servo driver, servo motor, frequency converter, frequency conversion motor, sensor, etc. PLC controls the machine to operate automatically according to the processing technology. HMI completes the human-computer interaction task.

 

4. Software sytem

The software system compares the data from glass measuring table with the order data, and automatically matches to the closest glass data. Meanwhile, the glass data is transmitted to the double edge grinder and other processing equipment for mode or batch production.  

 

Operating princple:

Manually or automatically put single sheet of glass onto glass measuring table. Glass measuring table convey, position and accurately measure dimensions of the glass length, width and thickness. Measured glass data is transmitted to the management system for comparison to match the order data and transmitted to the double edge grinder and other processing equipment for futher glass processing. Next single sheet of glass is put onto glass measuring table and start next operation cycle.

 

2.  Glass straight line double edge polishing machine.

Model No.: SM2242GT SM2225GTS

This machine is designed for polishing two opposite edges of glass at same time.

 

a) Control

This machine adopt Japanese Mitsubishi PLC control and 10” operator interface.  The Screen shows every detailed parameters of glass.  Each machine can be control by its own computer or controlled by main computer.  

The user’s right can be graded as operator/repair/administrator, preventing error happening, protect machine from misoperation.

 

b) High precision transmission.

The two conveyor timing belts are driven by two servo motors, with feature of high precision, high speed, high synchronization.

 

c) Mobile grinding section movement.

The mobile grinding section moves along linear twin ball bearing guide.  The transmission is implemented through ball screws, which is driven by servo motor, the Max moving speed of grinding section can reach 15 meter per minute.  This system also include a brake and gripping system, which can guarantee stable moving of the grinding section, low impact force.  This structure can guarantee the stability of gripping force for big size glass, even after machine running a long period of time.

 

d) Every double edger has one autoamtic middle support rail, which move along with the moving grinidng section, which support glass from middle position to prevent glass from bending.  For very big size double edger, we also supply one more portable support rail, which can be placed manually in need.

 

e) Upper track up&down system use sliding plate structure without stuck problem that traditional sliding sleeve system

 

f) Positioning system.

Glass loading position system includes four parts: fixed rollers, moving air gripping system, aligning blocks(one left and one right), top air pressing rollers(one left and one right).  Glass is precisely aligned and pressed tightly by the positioning system.  This system guarantees the grinding precision and polishing effect.

 

g) Easy adjustment

The raise/drop of upper tracking system and upper arris motors are driven by motors.  It can be set automatically according to different glass thickness.

 

h) Air Polishing system.

The polishing wheel is operated by air, which is controlled by PLC and electromagnetic valve, which can move forward/back according to glass position.  This system can automatically compensate the wear of wheels, giving consistent pressure to glass and getting same polishing result.

The polishing motor moving system use High precision dural linear slide rail system.

 

i) Basement and frame:

Are made of thick fabricated steel, which is treated by annealing furnace in our factory.  With good stability and anti-torsional strength, anti-bending strength.

 

j) Motor

Use high precision, low vibration ABB variable frequency motor.  The motors speed can be increased to 4300RPM through frequency inverter, the machine working speed can be increased to 20 meter/minute.

The motor control system has protection function of overload/lack phase/short circuit, electronic parts use international brand, standard types, can be found easily in the market, which reduce customer’s maintenance cost, increase production efficiency.

 

k) Top/Bottom Transmitting conveyor adopt timing belts.

 

l) Lubrication:

The twin ball bearing linear screw and guide rails are lubricated by automatic oil pump.

The machine also equipped a manual lubrication pump, which lubricate the sliding surface.

 

m) Working speed adjustment: Through frequency inverter.

 

n) Water tank, water tray, top/bottom timing belt cover, linear guide rail/ball screw covers are made in stainless steel.

 

o) Amperometer meter: 

check the wheel assportion.

Replacement-flexible waterproof connection module design intelligible indicator for up and lower arris motor ampermeter.

 

3.  L- shape Transfer table. Roller table and timing belt.

This machine composed of roller transmitting system and timing belt transmitting system.  The roller transmitting system is driven by chain, speed is controled by inverter accoring to the setting speed.  

Timing belt transmitting system can be raise up and lower down.  When glass come out from first double edger, the timing belt system will be raised up.  Glass will be moved to right positon and then lowered down on roller transmitting system.

Timing belt conveyor system use aluminum profile body.
