3.3Description of the system characteristics

3.3.1 Design standard

The equipment strictly is accordance with the EU CE standardEN13155:2003, To carry on the design on based of US ASME(Mechanical engineering association)B30-20-2006standard and Germany UVV18standard,Main design index is higher than the above standard.

(1)Safety factor:Main design is greater than 2.0,Vacuum system pressure value for calculation is 60%,The actual peak pressure can reach 85% degrees,Set aside about 40% degrees.

(2)Board of  overhang

To calculated according to the board overhang. (Minimum thickness)

Minimum thickness of plate: 3mm

Max. overhangL=1016mm

See below schematic diagram.

 

Remarks: If the board handling amount of overhang beyond the maximum allowable value,Can cause irreversible permanent deformation of board.

 

3.3.2 Suction forcecalculation :

Dia.230mm.

 

Note: The holding force mentioned above is calculate on 60% vacuum pressure, maximum vacuum degreeof the system will be up to 85% above in a normal working condition.

3.4Main Spare parts list and functional description.

The device includes the following main components:

1,Vacuum pump:

To choose Germanybrand of Becker,Oilless, air cooling, rotary vanes vacuum pump, bleed air rate 8m³/h,  and the max. Vacuum degree up to 85%;to save energy,  small and light,  maintenance-free, etc

Oil free air cooling type rotary vane vacuum pump, connected to 220V,, Three-phase power can produce vacuum, As a core part of vacuum system,  The highest vacuum degree 85%;

2,Vacuum pad:

To suction the work piece surface, Rubber in contact with the workpiece, ensure that won't cause damage to the workpiece surface.

3,Vacuum filter:

To eliminate the dust and particles in the air flow, ensure the lifetime of the vacuum pump;

4,Vacuum gauge:

To show the vacuum level to the operator, Provide security;

5,Vacuum pressure switch:

Pump-film type,When insufficient vacuum pressure, To give electrical signal to alarm system.

6, Manual slide valve:

To switch off the access of vacuum pump and suction pads between the air flow, Safety locks ,prevent accidental operation.

7,Vacuum non-return valve:

When the system power failure occurs, automatically shut off the vacuum pump and air channel, Lock the vacuum energyofvacuum tank.Provide enough pressure holding time, ensure the workpiece will not falling insuddenly.

8, Manual Ball Valve:

To manually open or close vacuum pump and suction pads pathway, convenient maintenance.

9, Alarm indicator lamp:

When the suction force of a single set of suction pads is insufficient, The corresponding indicator light alarm.

3.5 The advantages of the design

Standard design:

1) Vacuum tank.----When the power failure in suddenly, the pad always can holding the sheet not falling down less than 30 minutes and more.

2) Adjustable pad/beam-----Every two pads are installed on the two sides of the cross beams, each cross beam is moveable on the main beam, and each suction pad is also moveable on the cross beam, which can ensure a same equipment can handling the different sizes metal sheet.

3) More pad design to keep balance and safety handling-----Multipoint suction point can ensure the metal sheet high level not run-off the straight when handling the metal sheet.

4)Buzzer and warning light units and vacuum pressure switch-----in case of a power failure or vacuum leakage or fails to reach the set pressure, warning unit can control the red warning lights on, At the same time a buzzer sounded, Prompt operator treatment in time.

5) Ball valve control pad in individually------ Each suction pads are equipped with manual ball valve control opening and close which can ensure a same equipment can handle various specifications plate.

6)Spring cushion---- Suction pad rod up and down each be equipped with a spring cushion, When the plate is uneven,  The spring effect buffer action,  can make the suctionpad strength evenly , so as to ensure suction and lifting the safe and reliable.

7)Safety factor---There are 2.0  times safety factor in horizontal

 

Special advantages

8)     Vacuum pump intermittent start-up (Energy saving, extend the life of the pump)----When vacuum reaches to the specified pressure, vacuum pump automatically stops to achieve energy saving; when vacuum pressure is insufficient, it automatically restarts to achieve vacuum compensation.

9)     Rotatable design of sucker head-----Especially for curved plate, better suction and handling

10)  Pad special design---- The replacement best price is cheap, portable suction cup sealing ring to save freight expenses

11) Surface treatment---- Selection of high quality steel material, welding part of the grinding, The main structure of the use of heat paint,can adjustable beam surface after polishing, electroplating treatment, Avoid damp environment and rust

3.6Operational control instructions of vacuum lifter

3.6.1Withboard joint:

Control of the driving crane, Make the vacuum lifter move to above of the sheet metal, make the vacuum lifter move to the upper of the sheet material.

3.6.2Boardsuction:

Push forward the hand slide-valve, Suction pad began to automatic suction plate. when the vacuum degree reaches requirements, meet the suction conditions, the green light is lit up, The warning stop buzzer, Lifting ready.
