The development of a full-automatic unbaler was very complicated work because the sizes and grades of bales have so wide a variety. The biggest diffuculty in the development is the damage of baled pulp during shipment, especially with tightened wires overlaid by the broken bailing paper.
The newest full-automatic unbaler consists of an unloader and wire cutter with turner and a wire gripper-puller with wire cutter, and the unbaler equipped with a turning station and a vacuum pump. The accuracy of the positioning of the wire cutting and gripping device is ± 0.5mm using a servomotor and a pair of magnetic sensors. The construction of the suction pads is so special that any air leakage through the clearance between the embossed baling paper and the suction pad or an opening of broken baling paper does not affect the unbaling action.

The work of removing the pulp bale is a big problem nowadays, because of not only its labor cost for simple work, but also worker's security.
We, herewith, would like to introduce “Full-Automatic Pulp Bale Unbaler System”, newly developed and patented in cooperation with our client Tokushu Paper Manufacturing Co. The system does not require even one operator, namely only need a helper who can approach it in case of emergency.
Three to four piled bales of pulp, after being loaded on the feed conveyor are separated to each one with the unloader. The centering apparatus adjusts bale's position against the conveyor, and then a bale comes to just above the turner.
“Automatic Wire Cutter with searcher” equipped with magnetic sensor finds out the wire bandles on the pulp bale during its scanning action on bale's surface and cuts them off automatically, and then the wires are chopped to about 200 mm length during being pulled out and conveyed to junk box with a small conveyor.
“Wire Pulling Out Apparatus” located on the opposite side of the turner, fineds out the same wire with the above one. The servomotors controle the movement with accuracy.
Both top and bottom bales are taken off with “Unbaler”. It has special six to eight suction pads, which satisfactorily work even on the embossed bailing paper and sometimes even on partially damaged bales during its transportation.
Whole system is controlled with central computerized control panel. Time cycle is about 80 seconds per one pulp bale, resulting in potentially having the capacity of 1, 080 pulp bales of regular size and weighing max. 280 kg per one. Speed of the system can be increased by applying double unit partially. As to the pictures of the machines, please refer to them illustrated on MR. M. Hanaya's report.
