The coil stacking machine is normally operated as the last procedure in a coil processing line, which can stack the wrapped coils on wooden pallet automatically. It is available to stack the products with different sizes. The hydraulic-mechanical combined with a transmission system makes the operation quick and smooth.
The coil is proceeding among others rollway and a centering system take action in order to center the axle of the coils and ensure a perfect pile of coils on pallet.
As the coil reach the right discharge position, the lifter take up it (by vacuum system or mechanical one) and goes to place it on pallet placed into the discharging rollway station till the set pile is reached. As the pile is finished a weighing unit can optioned to detect the final weight of the packaging.
Lifting & Stacking system is designed to operate with vacuum pick up or mechanical one independently or in combination, In fact as the vacuum system is in operation the mechanical system will protect the coils against the fall down of coils so increase the safety of the system.
If we use vacuum system, the coils can be stacked one over the other, if we use the mechanical one, a spacer (about 30×30 mm) in between the coils is needed.
Lifting up system : By vacuum pincher only in case of nude coil
Lifting weight: Vacuum system up to 500 Kg. , mechanical system up to 2500 kg.
Stack height : 1200mm including pallet and spacers
Mecahnical lifting unit description
The coil positioning automatic for and moving to lifting position.
The mechanical lifter starts to working while sensor detected the coil in right position.
Four arms of mechanical lifter closer to coil and clamped the coil
Lifting the coil and move to the pallet for stacking.
Releasing the coil while it in pole.
Vacuum unit description
The unit is equipped with independent suction rings
An oil free rotary vane vacuum pump is applied. The max vacuum degree can be above 85%, and doesn’t need lubricant, coolant etc.
The unit is equipped with alarm buzzers units and warning light, in case of power failure or vacuum leak, the alarm units will warn the operator to dispose with the problems timely; As the pressure reach the safety value, the green indication light goes on and the operator can continue with movement and lifting operations.
A vacuum accumulator is also applied, in case of sudden power off, it can still provide the right suction to the copper coil for more than 5 minutes, which will not cause any equipment damage and other accidents.
The theoretical max load weight of the vacuum lifter can reach 1800kgs, so it has more than three times of safety factor with respect to coil weight 500kgs.
The unit is CE certified and conforms to the requirement of EU regulation.
