Working Principle

1). Product will be infeed to metal detector from output conveyor on packaging machine;
2). If product do not contain metal, it will be passed to check weigher for checking weight;
3). If product contain metal, metal detector will send a signal to check weigher, check weigher PLC will ask reject arm to reject this bag into left hand bin;
4). When product come to check weigher, if actual weight over or less preset weight, check weigher PLC will ask rejct arm to reject this bag into right hand bin (reject bin is optional);
5). If product weight qualify, it will be passed into next equipment;
6). If unqualify product did not reject out and still go to next equipment, machine will alarm and stop working (Option);

Optional reject bin function:
When rejected products full up to 2/3 height, it will detect by photo sensor, and then machine will alarm to remind operator to take out the rejected products before it full of the reject bin

  1). SIEMENS PLC & 7" touch screen, more stability and easier to operate;

2). Apply HBM load cell ensure high accuracy and stability (original from Germany);

3). Advanced DSP technology to refrain product effect;

4). Digital signal processing and transmission;

5). Solid SUS304 structure ensure stable performance and precise weighing;

6). Reject arm, air blast or pneumatic pusher for selecting;

7). Belt disassembling without tools, which is easier to clean;

8). Arm device show clients clearly for the production situation (optional);

Options:

1). Reject Bin
Function: collect rejected products when unqualify bags were rejected out

2). Push rejector and air blow rejector
Function: for heavy and light proudcts rejection

3). 360°rotary HIM
Function: Operator can check the production data in 360°.
