Soft containers of "Big Bag" type


Big Bag unloader and set batching SRD-500 LOGIC

In the cement market the cement of Chinese, Turkish and European countries production is widely sold today. The cement comes generally in soft containers of type "Big Bag". To operate with soft containers "Stroymechanika" company designs and manufactures the equipment allowing to unload and fill the bulk material bags.

Enlarging the nomenclature of the manufactured production "Stroymechanika" company offers absolutely new plant from the series of equipment to operate with soft container. It is a bag unloader with intelligent system of specified batching SRD-500 LOGIC.

Work with bag unloader SRD-500 LOGIC:
Soft containers ready to be unloaded are mounted on the top the feed hoper of the unloader with help of a loader before pricking on knife intended to open containers and mounted in the inner surface of the hopper.

During the unloading of the soft containers with valve the knife to open the containers is removed from the inner surface, and the valve operation is made throughout inspection door. In the bottom of the feed hopper the removable screen serving to separate lumps of material.

After the container is installed the weighting system is started. One need to set up the portion mass on the display of the weighting panel of the station ET-02M and press the button "START". The disk shutter is opened and at the same time the drive of screw conveyor is powered, that helps the material enter the mixer or tank prepared beforehand. As the last portion is weighted. The screw is emptied, then press the button "PAUSE" and intelligent weighting system will store quantity of the unloaded material.

The empty container is removed from the feed hopper and the new one is installed, then repress the button "PAUSE" and the system restart the material weighting. The program Whale Pro Logic 3 developed just to program logically the devices of "VS-" company control the mechanisms of the intelligent weighting system. The COM port RS 232/485 transmit the program on the device, that disposes of the necessity to change firmware download of the device if this or that changes in operation algorithm are made. With help of Whale Pro Logic 3 the very flexible and quick adjustment of the control algorithm, adding new fictional features into the control system is made.

The mass of the unloaded portion is set up on the display of the weighting terminal ET-02M, installed on the door of the device electric box. The weighting station receives a signal directly from measuring sensor and one not need the connection of the intermediate traducers of signal levels. The weighting device has an indicator, control keyboard, USB port to connect with a computer, interface RS-485 to connect with modules and computer, and different Kermit types.
