Abstract:The tissue packing machine is mainly used for the bagging of various specifications of soft tissue, instead of traditional manual packaging, it has the characteristics of fast speed and neat and beautiful packaging. This paper focuses on the introduction the system of INVT GD18 and DA180 in Tissue packing machine.

Keywords: GD18, DA180,Tissue packing machine

This tissue packing machine is a semi automatic equipment.Use INVT GD18 to control two conveyor belt moving the tissue. Tissue enter the packaging area in batches through the limit switch. The tissue are arranged according to the packaging requirements by servo, and sent to the left and right areas for bagging and sealing, and the tissue is manually removed at last step. The movement of packaging part is controlled by air cylinder. The operation of solenoid valve is controlled by PLC.

4.Debugging steps

(1)Check whether all I/O points of PLC, electron magnetic valve action and direction of valve are correct. Whether the corresponding signal and instructions of HMI is correct.
(2)Debug the motion track, speed, return to zero action and fault action of each single servo respectively. Total of five axes, slitting paper, horizontal devide layer, vertical devide layer, left and right push material.
(3)Semi automatic logic continuous adjustment, automatically return to zero point after pushing paper, and automatically devide the paper through sensor.
(4)Debugging alarm and pre-warning and other fault response, various high and low speed debugging.
