Crossclipping and bundling system and method for veneer packets
An apparatus for clipping ends of a book of sheets includes a first detector for detecting a first end of the book of sheets, a clipper positioning system and a first clipper including a knife. The clipper positioning system is adapted to automatically position the first clipper to a proposed first clipping position based on the detected first end of the book of sheets. A method of processing a plurality of sheets includes assembling the plurality of sheets into a book of sheets, detecting a first end of the book of sheets to propose a first position for clipping the book of sheets, positioning a first clipper based on the detected first end of the book of sheets, advancing the book of sheets to an infeed conveyor, detecting, the presence of the book of sheets in the infeed conveyor, advancing the book of sheets to the first clipper, clipping the first end of the book of sheets, and advancing the book of sheets from the first clipper.
1. An apparatus for clipping ends of a book of sheets of wood veneer, the apparatus comprising
a first detector for detecting a position of a first end of the book of sheets of wood veneer,
a second detector for detecting a position of a second end of the book of sheets of wood veneer,
a clipper positioning system,
a first clipper including a first knife,
a second clipper including a second knife,
a first bundler operable to automatically bundle the book of sheets of wood veneer adjacent the first end of the book of sheets of wood veneer, and
a second bundler operable to automatically bundle the book of sheets of wood veneer adjacent the second end of the book of sheets of wood veneer,
wherein the clipper positioning system is adapted to automatically position the first clipper at a proposed first clipping position relative to the book of sheets of wood veneer based on the position of the first end of the book of sheets of wood veneer and to automatically position the second clipper to a proposed second clipping position relative to the book of sheets of wood veneer based on the position of the second end of the book of sheets of wood veneer,
wherein the first clipper further comprises the first bundler to permit the first clipper to bundle and clip the book of sheets of wood veneer, the first bundler being a reel-type bundling mechanism, and
wherein the second clipper further comprises the second bundler to permit the second clipper to bundle and clip the book of sheets of wood veneer, the second bundler being a reel-type bundling mechanism.
2. The apparatus of claim 1 wherein the first clipper is adapted to be manually movable from the proposed first clipping position.
3. The apparatus of claim 1 wherein the clipper positioning system comprises a stageless positioning system.
4. The apparatus of claim 1 wherein the clipper positioning system includes a servo-controlled motor.
5. The apparatus of claim 1 further comprising a first infeed conveyor including a first sensor for detecting a book of sheets of wood veneer positioned in the first infeed conveyor.
6. The apparatus of claim 5 wherein the first infeed conveyor is adapted to transfer the book of sheets of wood veneer to the clipper positioning system after the first sensor detects the book of sheets of wood veneer.
7. The apparatus of claim 6 wherein the first clipper includes a second sensor for detecting that the book of sheets of wood veneer is properly positioned for cutting in the apparatus.
8. The apparatus of claim 1 further comprising an outfeed conveyor.
9. The apparatus of claim 8 further comprising an automatic length measuring system, the outfeed conveyor being adapted to transfer a bundled book of sheets of wood veneer to the automatic length measuring system.
10. The apparatus of claim 7 further comprising a second infeed conveyor including a third sensor for detecting a book of sheets of wood veneer positioned in the second infeed conveyor.
11. The apparatus of claim 10 wherein the first and second infeed conveyors are adapted to transfer the book of sheets of wood veneer to the clipper positioning system after the first and third sensors detect the book of sheets of wood veneer.
12. The apparatus of claim 10 further comprising a third infeed conveyor.
13. The apparatus of claim 12 wherein the first, second, and third infeed conveyors are adapted to transfer the book of sheets of wood veneer to the clipper positioning system after the first and third sensors detect the book of sheets of wood veneer.
14. The apparatus of claim 1 wherein an infeed conveyor is operable to convey a book of sheets of wood veneer to an outfeed conveyor after the book of sheets of wood veneer has been bundled.
15. The apparatus of claim 1 wherein the proposed first clipping position is one of a plurality of clipping positions, and at each of the plurality of clipping positions, the first clipper is movable between (i) a disengaged position in which the knife is spaced apart from the book of sheets of wood veneer, and (ii) an engaged position in which the knife is engaged with the book of sheets of wood veneer.
