Abstract
A case cutter apparatus for cutting a container has a conveyor for moving the container in a single direction, a measuring device measuring a length, a width, and a height of the container, a controller for controlling the apparatus and for receiving information from the measuring device, and a first cutting assembly and a second cutting assembly positioned along the conveyor. The first cutting assembly includes an indexing assembly holding the container in a predetermined position during cutting, a carriage moveable in a cutting direction transverse to the direction of the conveyor, and two cutting blades attached to the carriage. The second cutting assembly includes two belts each having a cleat thereon for pushing the container through the second cutting assembly in the direction of the conveyor, and two cutting blades.
Claims20
An apparatus for cutting a container having a top, a bottom, and two pairs of vertical opposed sides, the apparatus comprising:
- a conveyor having a horizontal surface, configured for moving the container in a single direction of movement;
- a first cutting assembly positioned along the conveyor, configured for cutting the first pair of vertical opposed sides of the container, wherein the first cutting assembly comprises a first powered rotary cutting blade and a second powered rotary cutting blade that are moveable in a first cutting direction generally transverse to the direction of the conveyor and are each powered for rotation on a generally vertical axis to be configured for cutting the first pair of vertical opposed sides of the container, wherein at least one of the first and second cutting blades is moveable along a horizontal axis generally parallel to the conveyor direction to adjust the assembly to a length of the container;
- and
- a second cutting assembly positioned along the conveyor, wherein the second cutting assembly comprises a third powered rotary cutting blade and a fourth powered rotary cutting blade that are each powered for rotation on a generally vertical axis of rotation to be configured for cutting the second pair of vertical opposed sides of the container,
- wherein the conveyor is configured to move the container through the first cutting assembly to cut the first pair of vertical opposed sides and the second cutting assembly to cut the second pair of vertical opposed sides in the single direction of movement.

An apparatus for cutting a container having a top, a bottom, and four vertical sides, the apparatus comprising:
- a conveyor having a horizontal surface, configured for moving the container in a conveyor direction;
- a first cutting assembly positioned along the conveyor, comprising a first cutting blade that is powered for rotation on a generally vertical axis and is moveable horizontally and generally transverse to the conveyor direction for cutting a vertical front side of the container and a second cutting blade that is powered for rotation on a generally vertical axis and is moveable with the first cutting blade horizontally and generally transverse to the conveyor direction for cutting a vertical rear side of the container, the vertical rear side of the container being generally parallel to the vertical front side, wherein the first cutting blade is fixed against movement along a horizontal axis generally parallel to the conveyor direction and the second cutting blade is moveable along the horizontal axis generally parallel to the conveyor direction to adjust the assembly to a length of the container;
- and
- a second cutting assembly positioned along the conveyor, comprising a third cutting blade for cutting a vertical left side of the container generally parallel to the conveyor direction and a fourth cutting blade for cutting a vertical right side of the container generally parallel to the conveyor direction, the vertical left side of the container being generally parallel to the vertical right side, wherein at least one of the third cutting blade and the fourth cutting blade is movable generally transverse to the conveyor direction to adjust the assembly to a width of the container, and
- wherein the conveyor is configured to move the container in a single direction of movement through the first cutting assembly to cut the vertical front and rear sides and through the second cutting assembly to cut the vertical left and right sides.

An apparatus for cutting a container having a top, a bottom, and four vertical sides, the apparatus comprising:
- a conveyor having a horizontal surface and being configured for moving the container in a direction;
- a first cutting assembly positioned along the conveyor, comprising a first powered rotary cutting blade that is powered for rotation on a generally vertical axis and is moveable in two opposed directions along a first horizontal cutting axis for cutting a first vertical side of the container and a second powered rotary cutting blade that is powered for rotation on a generally vertical axis and is moveable in the two opposed directions along the first horizontal cutting axis for cutting a second vertical side of the container, the second side of the container being generally parallel to the first side, wherein the first and second cutting blades are powered for rotation while moving in both opposed cutting directions to adapt the first and second cutting blades to cut the container in either opposed cutting direction along the first horizontal cutting axis, wherein the first cutting blade is fixed against movement along a horizontal axis generally parallel to the direction of the conveyor and the second cutting blade is moveable along the horizontal axis generally parallel to the direction of the conveyor to adjust the assembly to a length of the container;
- and
- a second cutting assembly positioned along the conveyor, comprising a third cutting blade for cutting a third vertical side of the container in a second horizontal cutting direction generally transverse to the first horizontal cutting axis and a fourth cutting blade for cutting a fourth vertical side of the container in the second horizontal cutting direction, the fourth side of the container being generally parallel to the third side,
- wherein the first horizontal cutting axis is generally transverse to the direction of the conveyor and the second horizontal cutting direction is generally coaxial to the direction of the conveyor, and
- wherein the conveyor is configured to move the container in a single direction of movement through the first cutting assembly to cut the first and second vertical sides and through the second cutting assembly to cut the third and fourth vertical sides.
