Conveying apparatus
This invention provides a conveying apparatus which conveys a workpiece. The conveying apparatus includes a pallet which supports the workpiece, a conveyor which supports one side of the pallet in a direction perpendicular to a conveyance direction from below the pallet, and includes a conveyance roller for conveying the pallet and a driving source for driving the conveyance roller, and a heaving suppression guide member which extends along the conveyor, abuts against the other side of the pallet in the direction perpendicular to the conveyance direction, and suppresses heaving of the pallet.
1. A conveying apparatus which conveys a workpiece, said apparatus comprising:
a pallet which supports the workpiece;
a conveyor which comprises a plurality of driven rollers arranged in a line; and
a guide member which extends along the line of the driven rollers on a first side of the line of the driven rollers,
wherein said pallet includes:
a main portion which has a plate shape and is placed on the driven rollers; and
a support portion which supports the workpiece,
wherein said main portion includes:
a first end at the first side; and
a second end at a second side, opposed to the first side, of the line of the driven rollers,
wherein said support portion is provided at the second end,
wherein the guide member faces upper, lower and end surfaces of the first end, and
wherein said pallet is supported by said driven rollers and said guide member such that the workpiece on the support portion is supported in a cantilevered arrangement.
2. The apparatus according to claim 1 , wherein said guide member includes a groove into which the first end of said pallet is horizontally inserted, and
wherein an inner wall of said groove faces the upper, lower and end surfaces of the first end.
3. The apparatus according to claim 1 , wherein:
said pallet includes a guided roller on the first end; and
said guide member includes at least one guide which abuts against said guided roller.
4. The apparatus according to claim 1 , further comprising a horizontal guiderail which extends along the line of the rollers between said conveyor and said guide member,
wherein said pallet includes, on a lower surface of said pallet, a pair of horizontal guided rollers which pinch said horizontal guiderail from two side surfaces of said horizontal guiderail.
5. The apparatus according to claim 1 , wherein said guide member includes an upper roller and lower roller which abut against an upper surface and lower surface of the pallet on the first end of said main portion.
6. The apparatus according to claim 1 , wherein said pallet includes a rotation mechanism,
wherein said support portion is connected to said main portion through the rotation mechanism, and
wherein said rotation mechanism supports said support member with the ability to rotate with respect to said main body member.
7. The apparatus according to claim 6 , wherein said rotation mechanism supports said support member with the ability to rotate about an axis parallel to the line of driven rollers.
8. A conveying apparatus which conveys a workpiece, said apparatus comprising:
a pallet which supports the workpiece;
a conveyor which comprises a plurality of driven rollers arranged in a line; and
a guide member which extends along the line of the driven rollers on a first side of the line of the driven rollers,
wherein said pallet includes:
a main portion which has a plate shape and is placed on the driven rollers; and
a support portion which supports the workpiece,
wherein said main portion includes:
a first end at the first side; and
a second end at a second side, opposed to the first side, of the line of the driven rollers,
wherein said support portion is provided at the second end,
wherein the guide member faces upper, lower and end surfaces of the first end,
wherein said pallet includes a rotation mechanism,
wherein said support portion is connected to said main portion through the rotation mechanism, and
wherein said rotation mechanism supports said support member with the ability to rotate with respect to said main body member about an axis parallel to the line of driven rollers.
