Abstract
A pallet carrying apparatus includes: a first pallet rail; a second pallet rail provided parallel to the first pallet rail; a first pallet feeding mechanism including a first endless belt on which convex portions and concave portions each extending in a belt width direction are formed; a second pallet feeding mechanism including a second endless belt on which convex portions and concave portions each extending in a belt width direction are formed; and a pallet moving mechanism configured to move a pallet. The first and second endless belt are provided in the vertical direction. Concavo-convex portions included in the pallet engage with the convex portions and the concave portions of the first and second endless belts.
Claims5
A pallet carrying apparatus configured to carry one or more pallets on which a workpiece can be placed, comprising:
- a first pallet rail on which the pallet is movably mounted;
- a second pallet rail on which the pallet is movably mounted, the second pallet rail being provided parallel to the first pallet rail at a predetermined interval in an up-down direction;
- a first pallet feeding mechanism including a first endless belt, the first endless belt being configured to circulate along the first pallet rail, convex portions and concave portions being formed on the first endless belt continuously and alternately in a belt longitudinal direction so that each of the convex portions and the concave portions extends in a belt width direction;
- a second pallet feeding mechanism including a second endless belt, the second endless belt being configured to circulate along the second pallet rail, convex portions and concave portions being formed continuously and alternately in the belt longitudinal direction so that each of the convex portions and the concave portions extends in the belt width direction;
- and
- a pallet moving mechanism configured to move the pallet from one of the first pallet rail and the second pallet rail to the other of the first pallet rail and the second pallet rail,
- wherein the first endless belt and the second endless belt are provided at a predetermined interval in the up-down direction, and disposed so that each of the belt width direction thereof corresponds with the up-down direction,
- wherein the pallet includes a linear motion block capable of moving on the first and second pallet rails, and a seat provided on the linear motion block, and
- wherein concavo-convex portions are provided on a side surface of the seat, the concavo-convex portions being configured to engage with the convex portions and the concave portions of the first endless belt in a case where the pallet is lowered to the first pallet rail by the pallet moving mechanism, and to engage with the convex portions and the concave portions of the second endless belt in a case where the pallet is raised to the second pallet rail by the pallet moving mechanism.
