Abstract
PURPOSE: To provide proper deviation in the action required for the opening or closing of the double-leafed hinged door designed to overlap each other to improve the checking function through the control of one directional control valve simply by using a throttle valve with a check valve.
CONSTITUTION: When opening lids respectively pivotted on the both sides of the upper opening of the packing box 1, with a directional control valve 8 switched to the left position, oil pathes 9 and 10 are connected to the discharge port of a hydraulic pump P. Thereupon, the check valve 11b is opened while a check valve 12b is closed, and a throttle valve 12 causes a lid opening/closing cylinder to stretch earier than a lid opening/closing cylinder 7. Thus, the lid 3 is opened earier than the lid 4. On the other hand, when the directional control valve 8 is switched to the right position while the door is opened, the check valve 11b on the return oil side is closed while the check valve 12b is opened. A throttle valve 11 causes the cylinder 7 to reduce earier than the cylinder 6. Thus the lid 4 is closed earier than the lid 3.
