Automatic batching packing machine LCS-100kg is equipped with a two-way arc gate and adopts the gravity feeding mode. It is particularly designed to pack granular materials with good mobility. Control actions of machine such as quick/ slow feeding, batching, bag clamping and bag discharging automatically. However, packing bags must be loaded manually. Set the quick/ slow feeding amount, control parameters, accumulated number of bags and other parameters on the instrument. Two scales work in turn to supply the weighed material into a bag clamping device. The machine features the compact structure, the easy operation and the high reliability.
The control core utilizes the internationally cutting-edge control technologies and algorithm. To improve the operating rate and the operating accuracy, we use the well-recognized high-performance CPU. We also select high-speed and high-precision A/D components for accurate and quick sampling.
LCS-100KG series is a programmed electromechanical machine with following benefits:
1,Combine an automatic weighing unit, a packing unit, a conveyor and a sewing unit. The structure is compact and reasonable. The appearance is fashionable and attractive. Generate a low noise level and save the energy. It is also easy for operation. So, it is able to increase the production efficiency, reduce the labor intensity and improves the working environment.
2,Relying on the high-speed weight data sampling, the automatic compensation, the auto-zeroing, the net-weight metering and other technologies, the machine realizes the accurate metering, the stable and reliable running, the long service life and the outstanding cost performance.
3,Use the digital filtering and the analog filtering technologies to eliminate the effect of mechanical vibration, material impact and other factors on the operating speed and accuracy.
4,The multi-function display, fault monitoring and self-test technologies and several data communication ports (to connect the computer or printer) facilitate the local control and the centralized control.
5,The full-enclosure design reduces the dust corrosion and disturbance, provides better working environment and extends the service life of machines.
6,The weighing hopper is equipped with 3 load cells in a balanced circuit and an enclosure.
The electrical system is structured simply. Use the weighing display and PLC for control. Do not use any relay or other electronic components except for switch indicator and electromagnetic counter. Such structure lowers the failure rate considerably, promotes the reliability of control circuit and facilitates the repair. The electromagnetic counter is used to prevent the data loss in case of power interruption.
It has been proven that the machine boasts the quick speed, the high accuracy, the good corrosion resistance, the strong immunity from interference and other features. As for comprehensive performance index, the machine is comparable to foreign competitors.

3.1 Principle drawing
3.2 Brief description of working principle
In the automatic running mode, the control system opens the feeder. When the preset value of quick feeding is reached, stop the quick feeding and activate (or maintain) the medium feeding. When the preset value of medium feeding is reached, stop the medium feeding and activate (or maintain) the slow feeding. When the preset lead is reached, stop the slow feeding. The instrument will judge if the package weight is stable. By then, a weighing cycle completes.
A scale with hopper or multiple hoppers (named to the number of equipped weighing hoppers that receive materials from a feeder, weigh materials and discharge materials into a bag via discharge gate). When the level sensor on the storage bin detects a level (upper level or lower level), a feeder starts working (materials fall under the effect of gravity and a single frequency variable screw/double screws/ belt operates). Stop feeding if the weight presetting is reached. After receiving the bag clamping signal, a control instrument sends a signal to open the discharge gate of weighing hopper. Materials flow from the weighing hopper to the bag. The discharge gate is closed automatically. When the control instrument receives the discharge gate closing signal (feeder restarts), the bag clamping unit releases the bag and the conveyor delivers the bag to the sewing machine and following stations. Such cycle is continuous and automatic.
