Automation System

PS Series - Bulk Proportioning Scale  (Catalogue available)

Last update 10/10/2008

Our PS series scales provides you with an semi-automatic or fully automatic system solution for packaging your products by weight. By utilizing different means of feeders, the machine can operate in a dual speed filling configuration, providing a fast and accurate filling. Depending on your application, 'gain in weight' or 'lose in weight' method of filling can be used. Our great and economical controller sets are suitable for a full range of weight filling applications, from filling a 20 g bottle to loading a 80 tons truck.

 

Rice Packaging Machines Apart from the general applications, we also specialize in packaging machines for the rice industrial.  The semi-automatic model require manual feeding of preformed PVC bags and then it will automatically perform the weighing, filling, vacuuming and sealing actions. The same model can fill and vacuum seal typical 2 kg, 5 kg, 8 kg and 10 kg packages but any required capacity can be set on the control panel easily. The control system will automatically adjust filling parameters for any inaccurate filling due to free fall or flow problem of the material with the *AFFC function. The semi-automatic model provides a very good value for the mass market. * AFFC: Automatic Free Fall Compensation

Good material handling is essential

To maintain the accuracy of the system, it is vital to supply an even, consistence and steady flow of material to the feeders. Our engineer can design specific equipment for handling your particular needs. Single or double screw feeders, vibratory feeders, multi-level of pre-feeding mechanism, conveyor belt feeders, gate valves, rotary valves... and many many more can be chosen from for different material characteristics.

Loss-in-Weight metering application

 

Simple, flexible operation is the key With our complete operation precedures, operation setup is just like a breeze. All the operator required to do is to enter the packaging weight and then off he go. No more nasty setup when changing products. After the one off initial setup, all filling error correction will be made by the machine automatically, totally transparent to the end user.
