Claims
- 1. A device for conveying molded pieces used for forming bottle-shaped containers, each of said pieces having a body, a flange formed on one end of said body and a body bottom formed on the end opposite said flange, said device comprising:
- piece supply means for slidably feeding said pieces to a near vertically inclined endless conveyor, said conveyor comprising;
- a chain-engaged drive sprocket;
- drive means for driving said sprocket at a constant speed in a predetermined direction;
- a guide sprocket, either said guide sprocket or said drive sprocket being a top sprocket located at the top of said endless conveyor;
- an endless drive chain connecting said drive sprocket and said guide sprocket;
- supporting-pushing attachments attached at equal, predetermined intervals along said drive chain, said attachments being capable of supporting the body bottoms of the pieces;
- upper and lower pairs of guide rails, said lower pair of guide rails being closer to said drive chain than said upper pair, said guide rails being parallel to and outside said chain, located so that the portion of said drive chain nearest said guide rails moves upwardly, said guide rails surrounding the flange of said piece when said piece is pushed upwardly by said attachments, said lower pair of guide rails being in contact with or immediately adjacent to said piece supply means so that the flange of a piece located at the end of said piece supply means nearest said endless conveyor contacts the lower pair of guide rails;
- piece exhaust means for slidably feeding said pieces from said endless conveyor at the top of said conveyor by engaging said flanges, said attachments extending outwardly from said chain a distance less than the vertical distance encompassed by said pieces when positioned along the top sprocket and supported by said piece exhaust means;
- a piece delivery portion for conveying out the piece conveyed to the top of said endless conveyor into said exhaust means, said piece delivery portion having a piece transfer chute plate secured to the tops of said guide rails, said guide rails being slightly bent along the peripheral surface of the top sprocket toward the piece delivery portion to provide an uppermost piece conveying position, said chute plate extending to said exhaust means directly above the top sprocket, said chute plate having a piece passing hole formed therein of a size to allow the flange of the pieces to pass therethrough.
- 2. The device according to claim 1, wherein said piece supply means comprises two bars slightly inclined toward said endless conveyor, said bars being spaced to slidably engage the pieces in a vertically flange upward position by holding the flanges of the pieces, each one of said bars contacting one of said lower pair of guide rails.
