Abstract

There is described a dumping device for use in a system for tumbling products, such as concrete blocks, bricks, paving stones or the like loaded in successive layers on a pallet. The dumping device comprise a pallet receiving structure pivotally mounted on a fixed frame, the structure including a tilting and a movable floor that receives the pallet with the layers of products thereon. The structure is first tilted to a predetermined angle corresponding to a product unloading position; thereafter, the floor is pushed intermittently so that the layers are unloaded in succession layer by layer onto a product conveying station and, thereafter, to a tumbler. Sensors are provided to indicate the presence or absence of the products at the conveying station and to give a signal to intermittently actuate the floor.

Dependent claims

In a system for tumbling products, such as concrete blocks, bricks, paving stones or the like, loaded in successive layers on a pallet, a dumping device for unloading said products onto a conveying station including an inclined slide surface for sliding said products onto a conveyor;

said dumping device comprising:
a fixed frame;
a product receiving structure pivotably mounted on said fixed frame;
said structure including a tilting frame and a movable floor adapted to receive said pallet with said layers of products thereon and to be movably displaced on said tilting frame;
actuatable means mounted on said fixed frame and engaging said structure to tilt said structure relative to said fixed frame from a product loaded pallet receiving position to a product unloading position;
pusher means mounted on said structure for displacing said floor when said structure has reached a predetermined tilt position whereby a first layer of said products is caused to slide onto said slide surface and said conveyor;
and
means actuating said pusher means to intermittently move said floor each time a layer of products has been unloaded and conveyed so that said layers may be unloaded in succession layer by layer.
