The QToploader consists of a trolley that moves horizontally with an attached scraper construction that moves vertically up and down following the top of the product layer in the storage area.
The storage area is filled by an overhead conveying system or by a reversing trailer emptying directly into the storage area. During the filling of the storage bay by a trailer the QToploader stays in parking position for safety reasons. During filling by an overhead conveyor, the QToploader can continue dosing.
After filling, the QToploader trolley moves to the back of the storage area and starts scraping the product to the front of the storage area near the discharge conveying system. It starts to stack the product at the front end of the storage bay. It continues stacking until there is no more product to stack.
After stacking, the QToploader switches to dosing mode. It brings the product onto the discharge conveying system, which is placed at 90 degrees to the storage area. If the product needs to be dosed during stacking, this dosing has priority.
After discharging, the scraper arm is pulled up and the trolley moves backwards to the beginning of the remaining stockpile of material. There the scraper goes down again and the full cyclus starts again. When there is no demand for product, the QToploader stays idle in standby, ready for dosing.
