The Glass hoisting

The installation of glass is a meticulous overall organization and construction. Before construction, check the personnel of each station, whether the various machines and tools are normal, and whether the measures are correct. Tools and parts for high-altitude operations should be placed in a tool kit to prevent objects from falling and hurting people. The glass can be hoisted after the inspection is completed.

(1) Check the quality of the glass, pay attention to whether the glass is cracked or chipped, and whether the position of the copper plate of the hanging clamp is correct. Wipe the surface of the glass with a dry cloth, and mark the position of the glass with a marker.

(2) Install an electric suction cup machine. The electric suction cup machine should be positioned, symmetrical, and slightly above the glass, so that the glass after lifting can avoid left and right deflection and rotation.

(3) Install manual suction cups and side protective rubber sleeves at appropriate positions on the glass. The manual suction cup on the glass allows workers working on different platforms to assist the glass in place when the glass is in place.

The advantages of vacuum glass suction cup spreader:

Small and lightweight, easy to handle workpieces, equipped with an oil-free vacuum pump, no external power supply; 

Time-saving, labor-saving, and cost-saving, convenient and quick to operate; 

With ergonomic design, sound and light alarm system, energy storage device, high performance, long service life And other characteristics; cooperate with the driving to form a complete lifting and handling solution. 

Application of vacuum spreader:

Glass processing, glass loading, and unloading, glass curtain wall installation, etc.;

suitable for workpieces with relatively flat and dense surfaces and relatively regular shapes. 

Working principle of vacuum spreader:

The vacuum suction cup is connected to the vacuum equipment (such as vacuum pump, etc.) through the air duct, and then contacts with other workpieces (such as glass, steel plate, etc.), and then starts the vacuum equipment to suck, so that negative air pressure is generated in the suction cup. 

Workpiece: 

When the workpiece is transported to the destination, the vacuum chuck is changed from negative air pressure to zero air pressure or slightly positive air pressure through the hand slide valve, and the vacuum chuck is separated to complete the task of transporting the workpiece. 

Vacuum spreader performance description:

1. The acousto-optic alarm system is the display of the spreader pressure gauge, and it works when the standard vacuum is 60%; the acousto-optic alarm is equipped with an automatic locking angle function when the load is 90 degrees vertical or horizontal.

2. Button control suction and discharge, energy storage and pressure preservation vacuum system, higher safety, continuous 360 rotation; manual rotation function, adjustable suction cup position;

3. The one-way valve is used in conjunction with the accumulator, which can accidentally cut off the power of the spreader during use, and can keep the workpiece in the adsorption state for 5-30 minutes without falling;

4. The extension rod can be assembled and unloaded to better adapt to the size and shape of various loads 

The selection of vacuum spreader:

1. The quality of the workpiece to be transported: determines the size and quantity of the suction cup.

2. The shape and surface condition of the workpiece to be transported: select the type of suction cup.

3. Working environment (temperature) of the workpiece to be transported: select the material of the suction cupAccording to different glass specifications, the assembly method of the equipment is different. 

The assembly methods are H type, I type, X type.

H type is suitable for ultra-long glass specifications such as 1400*7000*3-25mm

I Type is suitable for medium glass specifications such as: 1400*5000*3-19mm 3000*3000*3-19

X type is suitable for thick and small glass specifications such as 1600*4000*3-19mm

Operating instructions for vacuum spreaders:

1. Start-up of the vacuum lifter of the glass suction crane

Turn on the power switch on the control box, the vacuum pump is started, and the air in the accumulator is first evacuated to ensure sufficient vacuum. When the pressure is lower than 50%, the sound and light alarm lamp will alarm until the required vacuum pressure is reached. When the pressure reaches the set pressure, the vacuum pump will automatically stop running to save power. At this time, the vacuum hoist is in a ready state.

2. Positioning of glass suction crane

Control the movement of the lifting equipment so that the suction cup of the suction hoist is close to the surface of the glass. At this time, the suction cup of the suction hoist is fully fitted and sealed with the glass surface.

3. Glass adsorption

Push the manual hand slide valve on the operating handle. At this time, the suction cup is connected to the vacuum system, and the suction hoist automatically absorbs the glass. The vacuum pressure gauge will display the vacuum degree (pressure) at this time. When the pressure gauge shows 55% vacuum degree (-0.55kg/f), it means it can be transported. This process takes about 2-3 seconds.

4. Glass flip:

Pull out the locking shaft pin and push the suction cup holder forcefully to drive the workpiece to flip up. When it is about 90 degrees, the shaft pin automatically locks the suction cup holder. At this time, the 90-degree vertical flip of the workpiece is realized.

5. Glass lifting/discharging handling:

Control the electric hoist to transport the plate to the unloading position;

6. Glass release:

Pull back the manual slide valve on the operating handle to make each suction cup communicate with the atmosphere, then the vacuum pressure between the suction cup and the glass surface will disappear, and the glass will separate from the suction cup.

7. Repeat operation:

Operate the lifting equipment to move to the next board to be transported, and repeat step
