Conveyer assembly for a produce packaging system
View Patent ↗A conveyer assembly used as part of an automated packaging system is disclosed. The conveyer assembly allows the container filling process and produce leveling process to be combined as a single process station in an automated packaging system. The conveyer assembly includes a pair of elastic belts trained about two pulleys, four vibration isolation rollers, and a vibrator mechanism. The vibration isolation rollers are mounted to the frame structure and positioned at incrementally higher positions, which creates a slight incline to the conveyer belts over the first half of the conveyer run. The highest isolation roller, which is located at the center of the conveyer assembly, isolates the first half of the conveyer run from the vibrations generated by the vibrator mechanism. Consequently, the first half of the conveyer run where the produce is deposited into the containers is stable and free from vibration, which reduces the loss of produce due to spillage. The vibration mechanism only affects the second half of the conveyer run where the produce is leveled within the containers.
1. A conveyer assembly used in a fill station of an automated produce packaging system for packaging produce into containers, the conveyer assembly comprising:
a frame,
a first conveyer pulley and a second conveyer pulley each supported by the frame and horizontally spaced from each other,
a conveyer belt trained about the first pulley and the second pulley to form a top conveyer run upon which the containers travel in close side-by-side succession,
drive means for propelling said conveyer belt about the first conveyer pulley and the second conveyer pulley,
a roller supported by the frame between the first conveyer pulley and the second conveyer pulley, the roller contacts the conveyer belts so that the top conveyer run has an incline between the first pulley and the roller,
the roller constituting means for isolating vibrations imparted to the conveyer belt over the top conveyer run between the first conveyer pulley and the roller, and
vibration means mounted to the frame between the roller and the second conveyer pulley for imparting vibration to the conveyer belt to level produce deposited into a container from the hopper.
2. The conveyer assembly of claim 1 wherein vibration means includes a rotatable oblong paddle mounted to the frame so as to intermittently contact the conveyer belt, and a motor operatively connected to the paddle to rotate the paddle.
3. An automated produce packaging system for packaging small round produce into containers, the system comprising:
a frame, a hopper supported by the frame for metering produce into the containers, and a conveyer assembly supported by the frame for transporting the containers in succession past the hopper,
the conveyer assembly includes a first conveyer pulley and a second conveyer pulley each supported by the frame and horizontally spaced from each other, a conveyer belt trained about the first pulley and the second pulley to form a top conveyer run upon which the containers travel in close side-by-side succession, a roller supported by the frame between the first conveyer pulley and the second conveyer pulley, the roller contacts the conveyer belts so that the top conveyer run has an incline between the first pulley and the roller, the roller constituting means for isolating vibrations imparted to the conveyer belt over the top conveyer run between the first conveyer pulley and the roller, and vibration means mounted to the frame between the roller and the second conveyer pulley for imparting vibration to the conveyer belt to level produce deposited into a container from the hopper.
4. The conveyer assembly of claim 1 wherein vibration means includes a rotatable oblong paddle mounted to the frame so as to intermittently contact the conveyer belt, and a motor operatively connected to the paddle to rotate the paddle.
