PHU SON Corporation completed the installation and delivery of the HISNEG automatic lying flat bottom and edge polishing industrial machine – 2023 at SOMVANG GLASS factory – a loyal customer in Laos.

The machine is controlled by PLC + liquid crystal display

20 polishing head motors

Maximum glass plate grinding size: 5000mm

Barcode gun kit integrates with intelligent control software to ensure sequential receipt of work orders in sequence with multiple orders at once to automatically adjust operational data without entering work order data

The movement of 2 conveyor pairs by 2 servo motors + 2 drivers helps to ensure absolute accuracy of synchronization and working speed, convenient for connecting other automatic line operating systems connected to the machine (size and thickness gauges, washing machines, loading machines, automatic unloading machines…) according to new generation intelligent technology.

The central support bridge is always automatically positioned in the middle when changing the width of the glass to ensure that the glass is always flat without any human intervention.

The machine is designed with a conveyor clamp on a specialized heavy-duty industrial-type fan that operates at high speed, so water will rub off on the surface of the glass panel and the machine is equipped with a wind knife that blows pressure to help preliminarily clean the surface of the glass panel as soon as the glass comes out of the machine.

Horizontal movement by 1 servo motor + 1 driver is extremely fast and accurate to shorten the waiting time when changing the width of the glass.

Double-groove spiral shaft for precise operation and long-term durability

Electrical connection system and all electronic components according to European standards – CE.

The machine already has tools available for future investment needs to connect into a smart high-tech line including an automatic table for measuring dimensions and thickness (machine 1 and machine 2 receive data and align at high speed, fully automatic).

***** The differences of the completely new generation machine – NEW DESIGN, NEW CONSTRUCTION, NEW TECHNOLOGY, NEW SOFTWARE, NEW FEATURES – SMARTER, FASTER, EFFICIENT:

* The main body frame structure is designed with thicker steel and is heat treated and the width is up to 1.8m, the fixed body and the movable body are designed on a unified standard block placed directly on the chassis body to help the machine operate completely smooth, stable, and not deformed.

* The base structure of the fixed side base body and the movable side base body is stronger and more stable

* Precisely designed guide bar and torsion shaft, more durable and stronger

* The gearbox on both sides of the machine is designed seamlessly from the engine to the transmission to the transmission belt to be stronger, smoother and more accurate (the old design uses a sand shaft to connect the transmission between the gearbox and the conveyor belt, which is fragile, and the weak movement causes the ratio of the two conveyors to be out of sync)

* Lower conveyor support body is made of #304 hardened stainless steel to make it stronger and more durable (old material is hard plastic)

* The machine has a structure of 6 bottom grinding heads divided 3 + 3, in which 2 rough + fine diamond grinding heads and 1 fine grinding wheel in the group of 3 pre-grinding heads. With the design of 3 front ends (No. 1 ~ No. 3) rough grinding + fine and smooth bottom of the glass, the same design of 2 heads (No. 4 ~ No. 5) finely and smooth grinding on both sides of the glass, so if only coarse grinding is possible, the speed can be greatly increased when the glass runs through the position of grinding head No. 5.

* Lower edge grinding head: Using the most advanced design for the lower 45 degree edge grinding system of the glass plate by a 2-step operating structure with a motor on the top (connected to the grinding head rack via a speaker wire), it is very convenient for alignment, maintenance and smooth operation, better polishing line quality (the old design is a direct grinding head motor and is located at the bottom).

* The machine is designed with a drainage groove so that water does not overflow on the area of the grinding head slides (the old design did not have a drainage groove, so water may overflow into the slides of the grinding head racks)

* The upper pair of conveyor cleaning brushes is designed to be open for easy viewing, adjustment and replacement (the old form is the brush placed in the box)

* The groove of the grinding heads uses a straight slide system to help the ball head motor slide smoothly and operate more stably (the old type uses fish gill structure).

* The use of a more advanced water supply system structure reduces the risk of glass powder deposition and the stronger water pressure keeps the grinding heads free from the risk of water shortage to increase the perfection of the operation of each grinding wheel

* The structure of the glass inlet locator is designed in the form of fan-shaped steel sheets

* Drivers, inverters and transformers are installed separately into an independent electrical cabinet to prevent interference with other electronic components.

* All the slides of each grinding head rack are designed with a full lubricating oil supply system to help all grinding heads operate smoothly.

* The machine is equipped with a system to increase the tension of the upper conveyor belt by phiton and is automatically controlled, changing the conveyor belt only needs 1 operation on the screen without having to remove the bolts like traditional

* The machine is equipped with an ultrasonic sensor at the inlet to increase controllability during operation

* The machine is equipped with dual oil pump system with control valve for movable body. The slideway and torsion shaft are equipped with an additional pump and independent lubricating oil feeding system, which ensures that every part of the machine is always fully lubricated.

* Lubricating oil supply system, air pipeline, connection of wires, pipes connecting sensors are designed to be installed independently, making it easy to maintain and not affected by wet working environment.

* With energy-saving technology, by setting the time so that when the glass has not reached the grinding head, the motor will automatically stop and when the glass is reached, the motor will be restarted to operate smoothly.

* With smart technology, it is possible to turn on / off all polishing heads at the same time when rough grinding or can turn on / off each polishing head when there are different gloss level requirements of each order

* The pressure air duct that blows water pressure onto the surface of the glass plate is made of stainless steel which is more beautiful and durable than the traditional steel material
