Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a suspended conveyor device used for conveying doors, for example, in an automobile production line.

Conventionally, in this type of hanging conveyance device, a hanger device is attached to a trolley device guided by a conveyor rail, and the object to be conveyed (such as a door) is held and conveyed by the hanger device. According to such a conventional configuration, one hanger device can handle one
In this case, both the storage length and the number of hanger devices are required to correspond to the number of objects to be transported (the number of doors), and it is also extremely difficult in terms of space. In order to solve this space problem, conventional hanger devices were equipped with a telescoping or rotating mechanism to store the transported items (doors) in the width direction, but this caused problems.

It is an object of the present invention to be able to hold two objects to be transported with one hanger device, and to improve workability by shifting the positions of both objects in the transport direction during work, and to be able to store The object of the present invention is to provide a suspended conveyance device that can shorten the storage length by stacking both objects to be conveyed.

In order to achieve the above object, in the present invention, a first hanger is attached to a trolley device guided by a conveyor rail, a guide rail along the conveyance direction is attached to a side surface of the first hanger, and A second hanger is provided that is movable in the transport direction.

According to this configuration, by holding the objects to be transported with the first and second hangers, respectively, it is possible to hold two objects to be transported with one hanger device, and the number of objects to be transported can be The number of hanger devices can be halved. Furthermore, during work, by moving the second hanger in the transport direction guided by the guide rail on the first hanger side, it is possible to shift the positions of both objects to be transported in the transport direction. It is possible to improve workability for Furthermore, in the storage section, by locating the second hanger on the side of the first hanger, both objects to be transported can be overlapped, and the storage length can be shortened.

An embodiment of the present invention will be described below based on the drawings. 1 is a trolley device supported and guided by a conveyor rail 2, which includes a rear trolley 3 and a load trolley 4.
and a connecting rod 5 that connects both trolleys 3 and 4. A first hanger 6 is attached to one side of the connecting rod 5, and a balance weight 7 is attached to the other side. The first hanger 6 includes a sliding clamp device 8, a lower support 9, an end support 10,
It has a stopper 11 and the like. Guide rollers 12 and 13 are installed near the balance weight 7 and near the outside of the upper end of the first hanger 6, respectively, and steady rest guide rails 14 and 15 that come into contact with these guide rollers 12 and 13 from above are connected to the work line. will be placed along the Note that the storage section does not have guide rails 14, 15, so a balance weight 7 is required. A guide rail 16 along the conveying direction is attached to the outer side of the upper end of the first hanger 6 via a front-rear member 27 . A movable frame 18 supported and guided via a plurality of wheels 17 is provided on the guide rail 16, and a second hanger 19 is provided on this movable frame 18. The second hanger 19 includes a sliding clamp device 20, a lower support 21, an end support 22, a stopper 23, and the like. A guide roller 24 and a slide attachment 25 are provided on the outside of the upper end of the second hanger 19, and a steady rest guide rail 26 that contacts the guide roller 24 from above is provided along the work line. A withdrawal stopper 28 is provided at the drawer side end of the longitudinal member 27, and an automatic locking device 29 which can be elastically engaged with and detached from the movable frame 18 is provided at the drawer side end. 3
0 and 31 indicate the door (object to be transported).

In the work line, as shown by the solid line in FIG. 2, the movable frame 18 is guided by the guide rail 16 and brought into contact with the egress/retreat stopper 28. As a result, both hangers 6 and 19, that is, both doors 3
0 and 31 are shifted in the transport direction, and various operations are performed on the doors 30 and 31 while transporting them in this state. For transportation, the moving force of the conventional drive device (drive chain) is transferred to the trolley device 1.
This is possible by giving to the side. In the storage section, the movable frame 18 is retracted to the side of the front-rear direction member 27, as shown by the imaginary line in FIG. 2, and both hangers 6 and 19, that is, both doors 30 and 31 are arranged in parallel. This allows the overall length of the hanger device to be shortened.

Note that the storage length can be further shortened by sliding the second hanger 19 diagonally rather than completely parallel. Furthermore, by providing an allowable lap margin between the doors 30 and 31 between the hangers 6 and 19, the storage length can be shortened for both parallel slides and diagonal slides. Note that a sliding mechanism from the guide rail 16, movable frame 18, etc. may also be provided on the lower end surfaces of both hangers 6, 19. Furthermore, it is also possible to install existing hanger swing structures and hanger rotation devices.
