Abstract

A machine tool facility includes the following: machine tools; a first pallet stocker in which a plurality of pallets are arranged in parallel with a predetermined space therebetween; a second pallet stocker in which a plurality of pallets are arranged in parallel with a predetermined space therebetween, and which is disposed in parallel with the first pallet stocker; a conveyance car that conveys a pallet in a direction parallel to the row of the pallets of the first pallet stocker; a first transfer device for transferring the pallet between the first pallet stocker and the conveyance car; and a second transfer device for transferring, by horizontal movement, the pallet between the first pallet stocker and the second pallet stocker.

First claim

1 . A machine tool facility adapted to convey and transfer pallets between a machine tool and a pallet stocker, characterized by:
a first pallet stocker adapted to store an array of a plurality of pallets disposed at an interval; a second pallet stocker, arranged parallel to the first pallet stocker, and adapted to store an array of a plurality of pallets disposed at an interval; a carriage for conveying a pallet in the direction parallel to the array of the pallets; a first transferring device for transferring a pallet between the first pallet stocker and the carriage; a second transferring device for transferring a pallet horizontally between the first pallet stocker and the second pallet stocker.

2 . The machine tool facility of claim 1 , wherein the carriage is provided for moving between the machine tool and the first pallet stocker along a rail linearly extending the machine tool and the first pallet stocker.

3 . The machine tool facility of claim 2 , wherein the carriage has a based adapted to move along the rail, and first and second pallet supports provided on a top face of the base, and
wherein the first and second pallet supports are adapted to support a pallet parallel to the pallets held by the pallet stocker.

4 . The machine tool facility of claim 1 , wherein the first transferring device is provided on the carriage.

5 . The machine tool facility of claim 1 , wherein a rack is attached to a back side of the pallet, and
wherein the first transferring device comprises a moving bracket mounted to the carriage for moving reciprocally in a horizontal direction perpendicular to the extending direction of the rail, and a pinion, mounted to the moving bracket for moving vertically, the pinion having teeth engageable with the teeth of the rack of the pallet.

6 . The machine tool facility of claim 1 , wherein a rack is attached to a back side of the pallet, and
wherein the second transferring device comprises a base provided for moving reciprocally along a rail extending parallel to the rail for the carriage, a moving bracket mounted to the base for moving reciprocally in a horizontal direction perpendicular to the extending direction of the rail, and first and second pinions, mounted to the moving bracket for moving vertically, the pinions having teeth engageable with the teeth of the rack of the pallet.
