PIAB upgrades vacuum gripping and handling technology to a new level

The PIAB vacuum generator with an optimized negative pressure function can provide excellent solutions for the handling and handling of corrugated board and cartons in carton machinery such as cartoners and cartoners. Compared with similar products at home and abroad, PIAB's pneumatic vacuum system takes advantage of four features to bring vacuum grabbing and handling technology to a brand new realm, showing clear advantages in the industry.

1. Eliminate the risk of surface damage/scratches

Whether the suction cup will damage the cardboard surface depends on the degree of vacuum, so for each cycle or sample, the operator needs to fine-tune the lifting force and gripping force to achieve a moderate force so as not to damage the cardboard surface - this is usually It is difficult to operate. In most cases, enough suction is achieved by increasing the size of the suction cup instead of increasing the vacuum. If the degree of vacuum in the suction cup increases and the air leaks far below the expected/average value, the cardboard surface is more likely to be damaged. Compared to other methods, the use of PIAB vacuum generators and suction cups makes the gripping force more gentle. If used properly, it will ensure that the cardboard surface will not be damaged, and it will provide enough gripping force for most cardboard handling applications. Lifting power.

2. Up to 30% to 50% lower energy consumption

The increase or decrease in sucker lifting force is achieved by changing the sucker area rather than by changing the degree of vacuum. Therefore, lowering the vacuum slightly does not impair the lifting force, and lower vacuum and larger diameter suction cups can be used as much as possible. In materials that are prone to leaks, reducing the vacuum can significantly reduce the energy consumption of the air compressor. If the degree of vacuum is too high, it is very difficult to eliminate air leakage from the vacuum pump, which is a common feature of all vacuum pumps including the air compressor. If the degree of vacuum applied to the corrugated board/carton is reduced from 65-kPa [19.2 ‐ inHg] to 55 ‐kPa [16.2 inHg] and the suction cup diameter is 50 mm, 25–30% of compressed air energy can be saved. For a vacuum system that runs for 2,000 hours a year, this means that energy costs in excess of €100 ($125 USD) can be saved each year (accurate amounts are based on local electricity tariff standards).

3. Make it possible to automatically adjust the vacuum pressure

The piSAVE optimizer is a new type of automatic vacuum regulator specially designed for pneumatic vacuum pumps/vacuum generators. The operator can manually adjust the vacuum pump/vacuum generator and set a constant vacuum without having to set a constant air pressure. The regulator can increase or decrease the air pressure of the vacuum pump at any time through the sensing port's induction pump and the vacuum level of the vacuum system to maintain a constant vacuum. In order to ensure that the suction cup has the maximum lifting force and pick-up speed when adsorbing on the surface of the object, the vacuum pump uses full pressure at the beginning of the operation until the set vacuum is reached.
In a traditional heater/heat sink application, the operator needs to adjust the flow (or heat capacity) through the knob, which is time consuming and cumbersome. In the new system, just set the room temperature once, and the radiator can automatically adjust the flow rate (= heat capacity) to maintain the set room temperature. The same principle applies to vacuum systems that handle corrugated cardboard. The piSAVE optimizer automatically adjusts the vacuum level. Once set, the target vacuum level can be achieved to optimize the application performance.

4. The obvious economic advantage

The piSAVE optimizer is not only economical in terms of the environment, but also has the advantage of economical price, and the difference between the conventional compressed air regulator is very low – for newly installed applications, it will be a few months later. investment recovery. In the application of suction cups to capture corrugated board, the cost of upgrading the old system to install a negative pressure regulator can generally be recovered within one year.
