Palette conveyance mechanism and assembling line using it
First Claim
1. A pallet conveying mechanism in a vehicle assembly line comprising a first conveying line and a second conveying line for placing parts on a plurality of pallets in a conveying direction and for conveying the parts, the plurality of pallets have a symmetrical form with respect to a front and a rear side of each of the pallets, a first axis comprises a pallet moving direction, the pallet conveying mechanism carries a vacant pallet along a direction perpendicular to the first axis from one of a plurality of drop lifters which transfers from one of the plurality of pallets parts provided at an end point of the first conveying line, and loading the parts on one of the plurality of pallets to one of the plurality of drop lifters for transferring the parts provided at an opposing starting point of the second conveying line to one of the plurality of pallets and loading the parts on the plurality of pallets, said pallet conveying mechanism comprising;
- a plurality of rollers arranged so as to move said vacant pallet perpendicularly to the first axis,a driving means for rotating said rollers, anda guide means provided on a peripheral portion of the rollers for preventing said vacant pallet from veering while said vacant pallet is being conveyed.

11. A pallet conveying mechanism in a vehicle assembly line comprising:
-
a first conveying line; a second conveying line; a plurality of drop lifters; a plurality of pallets having symmetrical front and rear sides, wherein the plurality of pallets are conveyed along the first and second conveying lines; a plurality of rollers; a driving means for rotating said rollers; and a guide means provided on a peripheral portion of the rollers, wherein a first axis comprises a pallet conveying direction, wherein a vacant pallet is conveyed in a transverse direction which is a direction perpendicular to the first axis, wherein one of the plurality of drop lifters transfers parts from one of the plurality of pallets provided at an end point of the first conveying line to a starting point of the second conveying line, wherein the plurality of rollers are arranged to move said vacant pallet perpendicularly to the first axis, and wherein the guide means prevents said vacant pallet from veering while said vacant pallet is being conveyed in the transverse direction.
