Abstract
Feeding apparatus comprising an elevator, with a general structure similar to that of an escalator, having shelves of size proportioned for receiving articles; the shelves move continuously along an ascending active run of the elevator between fixed lower and upper platforms; a feed belt feeds the articles onto the lower platform and ejection means operate in synchronism with the elevator to eject the articles from the upper platform and feed them to the packaging machine, spaced apart axially at intervals by a predetermined spacing.
Claims5
Feeder apparatus for feeding articles such as sweetmeat products to a packaging machine, wherein the apparatus comprises in series:
- a continuously driven feed conveyor belt arranged to receive at least one longitudinal row of articles from a production plant;
- elevator means having shelves movable in the manner of an escalator continuously along a path which includes an ascending run and a decending run in the manner of an escalator, each shelf having a size corresponding to the size of the articles and having an upper comb-shaped support surface for the individual articles;
- a fixed lower platform adjacent and coplanar with the delivery end of the feed conveyor belt;
- an upper fixed platform, said lower and upper platforms having comb-like configurations staggered in relation to said comb-shaped support surfaces of the shelves so that the latter pass through said platforms, whereby each shelf in the ascending run of the elevator is displaced from a lower, loading, position in which it is coplanar with the lower platform to an upper, delivery, position in which it is coplanar with the upper platform;
- ejecting means;
- means operating the ejecting means in synchronism with the elevator, for removal of the articles as they are delivered to the upper platform;
- a fixed support structure;
- an upper horizontal drive shaft supported by the support structure;
- a frame articulated to the support structure for movement angularly about the axis of rotation of the drive shaft;
- adjusting means for adjusting the angular position of said frame;
- a lower horizontal shaft freely rotatably supported by the same frame, each of said upper and lower shafts supporting a pair of sprocket wheels around which pass two chains, and
- support means carried by said chains and supporting respective said shelves of the elevator means in the ascending run of the latter.
Feeder apparatus for feeding articles such as sweetmeat products to a packaging machine, wherein the apparatus comprises in series:
- a continuously driven feed conveyor belt arranged to receive at least one longitudinal row of articles from a production plant,
- elevator means having shelves movable in the manner of an escalator continuously along a path which includes an ascending run and a descending run in the manner of an escalator, each shelf having a size corresponding to the size of the articles and having an upper comb-shaped support surface for the individual articles,
- a fixed lower platform adjacent and coplanar with the delivery end of the feed conveyor belt,
- an upper fixed platform, said lower and upper platforms having comb-like configurations staggered in relation to said comb-shaped support surfaces of the shelves so that the latter pass through said platforms, whereby each shelf in the ascending run of the elevator is displaced from a lower, loading, position in which it is coplanar with the lower platform to an upper, delivery, position in which it is coplanar with the upper platform,
- ejecting means,
- means operating the ejecting means in synchronism with the elevator, for removal of the articles as they are delivered to the upper platform;
- and
- pressure means arranged above the lower platform and adapted to keep each article on the surface of said lower platform before it is lifted by one of the moving shelves of the elevator means;
- said pressure means comprise a rotor rotatable about an axis perpendicular to the longitudinal row of articles, transmission means connected to the elevator means for driving the rotor, said rotor having a plurality of active peripheral portions, identical to each other, which at their lowest point are spaced from the lower fixed platform by a distance substantially equal to the height of the articles fed over said platform and each of which acts upon a single article on the lower platform and is separated from the adjacent active peripheral portions by rotor notches which allow unimpeded ascent of the immediately preceding article on an ascending said shelf of the elevator means in use of the apparatus.
