Connecting control function
The vertical computer is the main controller for the whole processing line control include stop and start for the whole line, the actions of edger 1 and edger 2, transfer table, detecting table. The computer of edger 1 is to control the common functions itself include change the grinding wheels, lift the linear rail, zero point, etc. The computer of edger 2 is to control the common functions itself include change the grinding wheels, lift the linear rail, zero point, etc.
System provides 3 user levels for password changing, user adding, user deleting.
If there is problems in machine running, the alarm light will be on at the bottom of operation page, user can check the alarm information for details with real time status of PLC input and output, yield, etc.
Processing margin detecting
standard processing margin range is 2mm, if the processing margin of current glass exceed 2mm, the edger will automatically slow down the grinding speed to avoid chipping. The total processing margin shall be 1~6mm, if exceed this range, the edger will more and more slower even stop running.
Washing machine connecting
Washing machine shall be connected with edger 2. If the washing machine stop running, edger 2 will stop conveying the glass to avoid impact. Washing machine & edger 2 shall be connected by cable to make this synchronization function.
Benefits and Advantages
Equipment base bed
The base bed is made of formed square tubes with a thickness of 12mm and a size of 200*300, which can ensure stability and durability. After annealing according to the process requirements, the base bed is processed once with a large gantry milling machine, and anti-rust treatment is carried out in strict accordance with the process.
Main drive mechanism and width adjustment mechanism
The main drive uses two sets of servo motors to achieve synchronous operation, and the reducer uses a hard-tooth surface gear reducer, which has high transmission efficiency, fast speed and large load capacity.
The machine width adjustment is driven by a servo motor system using Taiwan's TBI high-precision ball screw. The screw adopts a diameter of 50mm. This is the largest diameter ball screw in the glass machinery industry. It plays a decisive role in the stability of high-speed opening and closing. Its advantages , fast running speed, high precision, and the maximum speed of dimensional change can reach 15m/min. It can cooperate with intelligent equipment such as inspection tables and loading and unloading tables to achieve fully automatic processing.
Manufacturing accuracy of grinding head motor
LIJIANG Glass manufactures some key parts of mechanical grinding heads and cooperates with domestic CNC machine tool companies to design a grinding head spindle assembly that is more suitable for LIJIANG Glass based on CNC spindle standards. The spindle has enlarged angular contact ball matching bearings. The motor is a Siemens energy-saving motor with a belt speed change and a rotation speed of 4500r/min.
Upper and lower chamfering grinding head device
The lower chamfer design installs the Siemens motor at the top instead of the bottom, which can avoid the problem of water intrusion and damage to the motor.
The upper chamfering adopts a special grinding head motor, and uses variable frequency speed regulation to increase the motor speed to 4000r/min. It is easy to maintain. At the same time, it also uses a positioning system for automatic position adjustment.
Processing performance of overall grinding
The coarse grinding head assembly of Siemens motor has a rotation speed of 4500r/min, which results in faster grinding speed and better processing quality.
The spindle part adopts a waterproof design with core technology. During high-speed operation, internal pressure will be generated inside the spindle and the water vapor will be discharged by itself, ensuring the stability of grinding and avoiding the problem of water intrusion into the spindle.
When choosing a direct-connected grinding head model, the grinding head is equipped with frequency conversion speed regulation, and the motor speed is also 4500 rpm. This can realize that when no glass enters, the equipment enters a dormant state, and when glass enters, the machine resumes processing status. Realize energy saving function.
Coarse grinding automatic feeding system
The working principle of the intelligent grinding head device is through a manual-automatic integrated reducer connected to a precision ball screw. The main computer system or PLC issues position instructions. The high-precision motor is connected to the ball screw to rotate and drive the grinding head motor and grinding head. The spindle assembly automatically moves to the position required by the instruction. When the grinding wheel detection assembly meets the detection conditions, it is controlled by the main computer system or PLC to start the detection. The detection block is retracted to the detection position by the cylinder, and then the intelligent grinding head feeding system drives the grinding wheel movement to touch and push the detection block. The grinding wheel size can be detected through feedback from the proximity switch or electronic ruler.
Automatic polishing system
The polishing cylinder adopts Taiwan Airtac φ50 adjustable cylinder with locking structure. The locking accuracy is high and the gap is small.
