The project was implemented for DrakaBag and consisted of four separate parts.
AUTOMATED LINE FOR PRODUCING ONE-CHAMBER PP BAGS
It is a fully automated line for producing bags from a semi-finished foil reeled on a coil. The foil is unwound from the coil and goes through the printers carrying out the description of the bags. Subsequently, it enters the cutting part where edges are cutaway and a cut-out for suspending is made. Another operation is the cutting of the foil into individual bags where, at the same time, small hoses are inserted into the bags for filling purposes. In the next step, two bags are sealed up at the same time on the pressing machine with an electronically controlled servo-axis. The last operation is cutting the bags in two with a knife.
Once all operations are carried out, the finished bags are transferred, by means of a chain conveyor with twelve positions, to the conveyor taking the finished bags from the protected area behind the fencing where they are manually handled by the operators.
DOUBLE WELDING MACHINE FOR MULTI-CHAMBER BAGS
It is a separate machine with an automated process of welding multi-chamber bags with a manual operation. The basis of the machine is the welding jaws welding the bags prepared by the operator. The operator puts the bags on a sliding cart that is manually taken to the welding area. Subsequently, the pressing machine is activated and welds up the bags. The carts can be put into the machine from both sides.
HOSE RE-WELDING MACHINE
This machine serves for re-welding hoses on the already produced bags. It is a manual machine controlled by means of PLC.
MACHINE FOR REMOVING HOSES FROM AN EXTRUDER
This automated machine serves for the removal of the produced hoses from an extruder and their cooling. A part of the machine is a cooling tub with water where the hoses are cooled after production and, subsequently, reeled to a coil with a finished hose. The reeling speed is controlled by means of PLC for the motion to be fluent and to avoid damage to the hose.
