Abstract

PURPOSE:To make an exact posture change at a prescribed position by forming a divided rail part of a part of a carrier rail, and making it possible to oscillate the dividing rail part in horizontal direction by an oscillating device to carry a supporting traveling object to be carried on a rail. CONSTITUTION:A rail 1 is installed on a ceiling beam 2 through a supporting device 3. The rail 1 is divided at a prescribed position to make a divided rail 1A, which is installed on a C-shaped connecting member 27 and is set at its shaft 26 so that it may oscillate freely through a bracket 25. By oscillating a movable base 35 of the lower end of a longitudinal member 41b hanging from the outer end of a horizontal member 31a installed in series outwards from the top end of the connecting member 27 by extension and retraction of a cylinder 36, the hanger device 16 of a mobile object 5 is oscillated together with the divided rail 1A. At the time of oscillating, the divided rail 1A is supported at an oscillating position by extension of a cylinder 44 used in a supporting device 41. It is thus possible for a hanger device 5 traveling on the rail 1 to oscillate at a prescribed place, being kept at that position.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a transport device using a moving body, which is employed to support and transport doors and the like, for example, in an automobile assembly line.

Prior Art This type of device is known, for example, from Japanese Utility Model Application No. 5310069.
The structure found in Publication No. 3 is provided.

In this conventional type, a conveyance hanger is attached to a connecting bracket from the trolley device side of an overhead conveyor (rail) via a longitudinal pin so as to be swingable from side to side, and rollers are attached to the sides of the conveyance hanger. Then, a cam rail for supporting and guiding the roller is disposed at a predetermined location in the transport path while supporting the door by the transport hanger, and by guiding the roller with the cam rail, the transport hanger is moved around the longitudinal pin. The door is swung to change its position.

Problems to be Solved by the Invention According to the above-mentioned conventional type, during normal transportation when the transportation hanger is hanging down, the transportation hanger easily swings from side to side due to vibrations, etc., which causes the door to shift in position with respect to the transportation hanger. As a result, post-work cannot be carried out smoothly and accurately, and in the worst case, the door may fall off.

An object of the present invention is to provide a transport device using a moving body that can perform normal transport stably without shaking and can change the posture of the transported object at a predetermined location.

Effects According to the configuration of the present invention, the movable body that supports the conveyed object via the support device is supported and guided by the rails and moves stably. After the moving object is transferred to the dividing rail section and stopped, the swinging device is operated to swing the dividing rail section in the left and right direction, thereby integrally moving the moving object supported by the dividing rail section. This allows the conveyed object to be swung, thereby changing the posture of the conveyed object. After performing the intended work on the object whose posture has been changed in this way, the moving body is moved from the divided rail section to the rail by returning the divided rail section to its original position by reverse operation of the swinging device. It is possible to transfer the vehicle and return to the intended movement.
