Abstract
A load of plastic material, including two sheets cut successively from a strip, is loaded into the mold of a molding press by way of a loading device including a conveyor having a number of spaced, parallel belts; a number of lifting elements arranged in rows between the belts; and a number of retractable bars insertable between the lifting elements for picking up the load. By way of an operating arm, the bars are moved up to the mold and then withdrawn in relation to a stop cross member so as to drop the load inside the mold.
Claims8
A device for loading plastic sheet material into a mold of a molding press, said device comprising a conveyor for feeding a load of plastic material into a position adjacent to said mold;
- wherein said conveyor comprises a number of spaced, parallel, horizontally-mobile transportation elements having gaps therebetween;
- a number of vertically-mobile lifting elements being provided in the gaps between said transportation elements, for removing said load off of said transportation elements;
- and means being provided for transferring said load off of said lifting elements and into said mold;
- and
- wherein said transportation elements comprise parallel, simultaneously-moving looped belts;
- each gap between said belts housing a row of said lifting elements.
An apparatus for loading plastic sheet material into a mold of a molding press, the apparatus comprising:
- a conveyor for moving a load of plastic material into a position adjacent said mold of said molding press, said conveyor including a plurality of substantially parallel simultaneously moving looped belts;
- a plurality of vertically moveable lifting elements disposed in gaps defined between said plurality of looped belts, said lifting elements for moving the load from said looped belts so that the load can be transferred into said mold;
- and
- wherein a plurality of said lifting elements is disposed in each of said gaps defined between said looped belts whereby said lifting elements in said gaps are moveable relative to said belts so as to remove said load from said belts.
