Following and explanation elevator 7 actions illustrate the essential of exercise of above-mentioned friction roll driven pallet conveying device simultaneously.

At first, make goods A standby, elevator 7 is dropped to the ground floor that to put in storage bed 6 is being set, by treating that lathe 3 makes goods A mounting to the supporting plate 10 of the elevator 7 that is positioned at the storehouse bed 6 of coming in and going out, is contained in goods frame 2 with goods A warehouse-in successively in treating lathe 3.

Make goods A under the situation of goods frame 2 outbounds, elevator 7 is risen and parallel motion on the position of the goods frame 2 of regulation.Certainly, also can side by side go up length and parallel motion and make its oblique course.

Elevator 7 one arrives than regulation goods frame 2 also high positions, and hook 48 is highlighted from hook case 47, then slowly descends.Like this, be stopped at the retainer 49 of regulation goods frame 2, make the walking track of walking track 13 and goods frame 2 of elevator 7 be positioned at same horizontal surface from the hook 48 that highlights of hook case 47.

Then, 37 work of the drive source of second driver train 35 on pallet conveying device 14a, the 14b, the push strut 39,39 that is retreated by the propulsive effort of this drive source 37 is forwards outstanding with the rear.Outstanding with the rear forwards by push strut 39,39, mobile station 17,17 be along guide rail 16,16 ' move to the front side and the rear side of elevator 7, simultaneously, near plate 46 along guide rail 16 ' move, near first, second near switch 43a, 43b.

Like this, can understand from Fig. 9 that first, second becomes ON state (Mode A) near switch 43a, 43b, second driver train 35 quits work, double-type friction roll 21,21 ' remain in the end position that advances with outstanding state.At this moment, be in the outer end of the guide plate 11 of taking advantage of the supporting plate 10a length direction both ends that are loaded with goods of carrying goods A, friction roll 21, the 21 ' clamping of energizing to the inside at ordinary times by the elastic force of compression spring 24,24.
