Abstract
An unloading mechanism for unloading automatically a box, includes an endless conveyor belt with a conveyor beld extension for transporting a box to be unloaded. A cage device is used to receive the box to be unloaded from the conveyor belt. Air cylinder actuators are operatively connected to the belt extension for pivoting downwardly the belt extension in order to permit rotation of the cage device. Rotary air cylinders are operatively connected to the cage device for rotating the cage device through approximately 165.degree. in a first direction in order to unload the contents of the box into a hopper.
Claims18
An unloading mechanism for unloading a box comprising:
- conveyor means including a conveyor belt extension for transporting a box to be unloaded;
- cage means for receiving the box to be unloaded from said conveyor means;
- means for pivoting downwardly said belt extension from a first horizontal position to a second position so as to permit rotation of said cage means;
- and
- means for rotating said cage means through approximately 165.degree. in a first direction in order to unload the contents of the box into a hopper only when said conveyor belt extension is in the second position.
An unloading mechanism for unloading a box comprising:
- an endless conveyor belt with a belt extension for transporting a box to be unloaded;
- a cage device operatively connected to said belt extension for receiving the box to be unloaded from the conveyor belt;
- air cylinder actuators operatively connected to said belt extension for pivoting downwardly said belt extension from a first horizontal position to a second position in order to permit rotation of said cage device;
- and
- rotary air cylinders operatively connected to said cage device for rotating said cage device through approximately 165.degree. in a first direction in order to unload the contents of the box into a hopper only when said belt extension is in the second position.
A method for unloading the contents of a box, said method comprising the steps of:
- transporting a box to be unloaded along a conveyor belt with a conveyor belt extension;
- receiving the box to be unloaded from the conveyor belt in a cage device;
- pivoting downwardly the conveyor belt extension from a first horizontal position to a second position so as to permit rotation of the cage device;
- and
- rotating the cage device through approximately 165.degree. in a first direction in order to unload the contents of the box into a hopper only when said conveyor belt extension is in the second position.
