Claims
- 1. An apparatus for conveying a board from an input position to a holding position comprising:
- conveying means for transporting said board in a conveying direction toward said holding position, said conveying means comprising conveyor rollers for conveying said board in the conveying direction, said conveyor roller shaving a rotation axis extending horizontally and transversely to the conveying direction, and guide members provided above said conveyed board, said guide members extending horizontally and transversely across said conveyed board to the conveying direction, and aligned with opposed respective ones of said conveyor rollers;
- means for forming a predetermined gap between said guide members and said conveyor rollers for preventing warping of the board conveyed on said conveyor rollers and held between said conveyor rollers and said guide members in said predetermined gap, said predetermined gap being correlated with a thickness of said board; and
- a crosswise base sliding means disposed in a path of said board along said conveying means between said input position and said holding position for sliding said board transversely to the conveying direction to thereby aligning a predetermined position of said board with another predetermined position of said apparatus as said board is being transported by said conveying means,
- said base sliding means comprising a threaded rod extending generally perpendicular to the conveying direction of said board and lying in a plane generally parallel to a plane of said board, first and second pulley support members threadedly engaged with said threaded rod to move together in the same direction perpendicular to said conveying direction when said rod is rotated, a pulley rotatably mounted on each of said pulley support members, an endless belt entrained between said pulleys, a support rod mounted generally parallel to said threaded rod, a pair of slide member supports slidably mounted on said support rod and connected on opposite sides to said endless belt so that said slide member supports move toward or away from one another as said endless belt is moved, and a pair of slide members mounted on respective ones of said slide members supports and disposed in a said path of said board.
- 2. An apparatus as recited in claim 1, wherein said guide members comprise rotary roll members.
- 3. An apparatus as recited in claim 2, wherein said gap forming means comprises radially projecting annular portions projecting from said rotary roll members at opposite ends thereof, said radially projecting annular portions contacting said conveyor roller axially aligned therewith to thereby define said predetermined gap.
- 4. An apparatus as recited in claim 3, wherein said annular portions are removable from said rotary roll members.
- 5. An apparatus as defined in claim 1, wherein said guide members are non-rotary.
- 6. An apparatus as defined in claim 1, wherein said sliding device comprises at least two members movable toward each other in synchronism for approaching opposing sides of said board.
- 7. An apparatus as defined in claim 6, wherein said sliding device comprises two pairs of said movable members, said pairs being separated by a conveyor roller and a guide member and being aligned with said conveyance direction.
- 8. An apparatus as defined in claim 7, further comprising means for laminating a laminating sheet onto said board disposed down stream from said conveyor rollers and said sliding device along said conveying direction.
- 9. An apparatus as recited in claim 1, further comprising holding members for holding said guide members and varying the amount of said predetermined gap between said guide members and said guide rollers.
- 10. An apparatus as recited in claim 1, further comprising supporting members for supporting said conveyor rollers and said holding members, and means for mounting said holding members for movement with respect to said supporting members, towards and away from said conveyor rollers.
- 11. An apparatus as recited in claim 10, wherein said holding members rotatably mount said guide members for rotation about their axes.
- 12. An apparatus as recited in claim 11 wherein said guide members each comprise a group of axially linked spherical shapes forming a sine curve.
- 13. An apparatus as recited in claim 12 wherein said conveyor rollers each comprise a plurality of radially projecting annular portions provided at spaced intervals along the axis of each said conveyor roller.
- 14. An apparatus as recited in claim 1, wherein the predetermined position of said board is a centerline of said board and the other predetermined position of said apparatus.
- 15. An apparatus as recited in claim 1, further comprising:
- means connected to one of said slide members for moving both said side members through said endless belt;
- board position detecting means for detecting a presence of a board and instructing said moving means to start moving said slide members; and
- board width detecting means for detecting that the predetermined position of said board coincides with the other predetermined position of said apparatus and stopping said moving means.
- 16. An apparatus as recited in claim 15, wherein said board position detecting means is disposed to detect a front end of said board.
- 17. An apparatus as recited in claim 1, further comprising a board holding member and a board supporting member for fixing said board in position at said holding position, said board holding member being mounted above said board at said holding position and being movable perpendicular to a plane of said board, and said board supporting member being moveable in a direction parallel to said plane of said board and supporting said board from below.
- 18. An apparatus as recited in claim 17, further comprising an air cylinder connected to one of said slide member supports for moving both said slide member supports through movement of said endless belt.
