Abstract
The invention relates to a system for dosed conveying and selecting of pellets for a moulding apparatus for lead frames, with which it is possible to prevent crumbled pellets or fragments and/or dust thereof being able to reach the molding apparatus arranged in a so-called clean room. For this purpose the system has structure for successively conveying pellets one by one, structure for selecting to length and feeding pellets to a transporting path, structure for reducing the transporting speed of conveyed pellets, structure for separating the pellets one by one and tranferring the pellets to a transport carrier, and means for transferring pellets from the transport carrier to a conveying device to a mold of a molding apparatus.
Claims15
A system for dosed conveying and selecting of pellets for a molding apparatus for lead frames comprising:
- infeed and selection means for successively conveying pellets one by one, selecting said pellets by length, and for feeding pellets to a transporting path;
- braking means for reducing the transporting speed of conveyed pellets along said transporting path, said braking means including a pellet outlet;
- pellet separating means positioned along said transporting path to receiving pellets from said outlet of said braking means and for separating the pellets one by one and transferring the pellets to a transport carrier;
- and
- transferring means for transferring pellets from the transport carrier to a mold of a molding apparatus.
A system for dosed conveying and selecting of pellets for a molding apparatus for lead frames comprising:
- infeed and selection means for successively conveying pellets one by one, selecting said pellets by length and removing those pellets of insufficient length, and for feeding remaining pellets to a transporting path;
- braking means for reducing the transporting speed of conveyed pellets along said transporting path, said braking means including a pellet outlet;
- pellet separating means positioned along said transporting path to receiving pellets from said outlet of said braking means and for separating the pellets one by one and transferring the pellets to a transport carrier;
- and
- transferring means for transferring pellets from the transport carrier to a mold of a molding apparatus.
