[0009]

However, such a conventional vertical and horizontal tray feeding mechanism has the following problems. (1) In order to guide the traversing wheels and vertical and horizontal wheels of the tray along the tray traversing rail and the tray traversing rail, attach the tray traversing guide and tray traversing guide to all the tray traversing rails and tray longitudinal feeding rails Because
These tray traversing guides and tray traversing guides have a large number of parts, which increases costs. (2) The tray traversing guide of each tray traverse rail and the tray traversing guide of each tray longitudinal feed rail are interrupted near the intersection of these tray lateral feed rails and tray longitudinal feed rails. When the tray is separated from the row of trays, the transverse and longitudinal wheels of the tray become free at this interruption. Also, when the tray is guided from the tray horizontal feed rail to the tray vertical feed rail, the vertical wheels of the tray are on auxiliary rollers,
The tray is unstable and may be offset slightly off the center of travel of the traversing wheels on the tray vertical feed rail. Especially when a relatively heavy vehicle is placed on each tray, there is a slight clearance at the connection part of each coupler of the tray, so that the tray tends to shift on the auxiliary roller due to the effect of this clearance. . When the tray is fed vertically in such a state, the traversing wheels of the tray roll on the tray vertical feed rail slightly off the running surface while free, and collide with the tray traversing guide. Engage, and a loud impact noise is generated at this time. It is desired to alleviate the collision and guide the tray smoothly. (3) Due to the configuration of the tray vertical feeder, the number of parts is large and the cost is high as described above. Also, in order to assemble and install the parts of the tray vertical feeder on site,
The number of work steps is large and work is not easy.

The present invention has been made to solve such a conventional problem.
To reduce costs by reducing the number of parts of the tray traversing guide and tray traversing guide, and to guide the traversing and traversing reliably and smoothly without freeing the tray. An object of the present invention is to reduce the number of parts to reduce costs, reduce the number of work steps on site, and facilitate installation work.

Fourth, the plurality of transverse wheels and longitudinal wheels are supported on the lower surface of the tray without protruding from the lower surface of the tray to the outer periphery, and the rail gauge of the tray lateral feed rail is set shorter than the vertical direction of the tray. The rail gauge of the tray vertical feed rail is set shorter than the lateral direction of the tray.
Thus, the tray can be formed with a minimum transfer path, and space efficiency can be improved.

At the same time, it is possible to reliably guide the traverse without making the tray free. Seventh
In addition, the tray traversing drive means includes an arm having engagement members at both ends, and a turning drive means for turning the arm in a horizontal direction. Eighth, the tray traversing drive means is installed in pairs between a pair of tray traverse rails. As a result, the tray can be reliably fed sideways with a simple device configuration. Ninthly, the tray traversing drive means comprises driving and driven sprockets disposed between two predetermined points set by taking a traversing stroke of the tray on the tray traversing path, and rotating between these sprockets. An endless chain that can be wound around, a driving device that rotationally drives a driving sprocket, and an engagement pin that is fixed to the endless chain and that can rotate between the two points. Tenth, each of the two points is set on an extension of the tray traversing guide on the tray traversing path. Thus, the tray can be reliably fed longitudinally with a simple device configuration. Eleventh, the drive unit is provided with a drive motor with a speed reducer, and the rotation shaft of the sprocket is directly connected to the output shaft. As a result, the number of components of the tray traversing drive means can be reduced and cost can be reduced. Twelfth, each part of the tray traversing drive means is integrally assembled on one base frame to form a unit. Thereby, the number of work steps on site can be reduced, and the installation work can be facilitated.
