DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 and 2, reference numeral 1 denotes a suspended monorail train as a moving body for transportation, and a ceiling-side suitable height. A pair of front and rear trolleys 5 and 6 provided with wheels 3 and 4 fitted to the guide rail 2 installed on the guide rail; a propulsion linear motor 7 having a bottom portion of the guide rail 2 as a secondary conductor; An elevating body 9 having a hanger 8 attached to a lower side, and an elevating drive means 10 for elevating the elevating body 9
The lifting drive means 10 comprises a plurality of belts 11 for suspending the lifting / lowering body 9 and a drive pulley 12 for winding and feeding the belts 11.

The propulsion linear motor 7 and the driving pulley 1
2, a current collecting unit 1 attached to the trolley 5 from a power supply line (not shown) laid on the side surface of the guide rail 2.
Power is supplied via the power supply 3. On both left and right sides of the elevating body 9, brackets 15, which are supported by an elevating guide roller 14 that is fitted to a fixed steadying guide rail when the elevating body 9 is lowered at a predetermined unloading place, are protruded.

[0007] The seat support hanger 8 has a backrest portion 16 that hangs substantially vertically from one of the left and right sides of the elevating body 9.
And a support portion 17 that is provided slightly obliquely upward from the lower end of the backrest portion 16 to the other left and right sides of the elevating body 9.
A pair of left and right positioning arms 18a, 18b projecting substantially horizontally from the middle height position of the left and right sides of the backrest 16 to the same side as the support portion 17, and a sheet detecting means 19;
It is composed of

More specifically, the hanger 8 for supporting the sheet comprises two substantially U-shaped bent rod-like members (steel pipes, etc.) 20a and 20b each having an intermediate height at the vertical portion and a height near the lower end. Are connected and integrated with each other by horizontal connecting members (steel pipes and the like) 21a and 21b, the vertical portion thereof is the backrest portion 16, the lower two fork-like portions are the supporting portions 17, and the upper two The fork-shaped part of
The mounting portion 22 is provided on the bottom surface of the elevating body 9. Further, a pair of left and right rod members 21a and 21b in the backrest portion 16 are connected to the positioning arms 18a and
18b is deformed so that the portion to which it is attached is the maximum width, and the lower portion therefrom is moved toward the center.
The width of the portion 6 is reduced to a predetermined size.

The sheet detecting means 19 is mounted at a central position near the lower end of the backrest 16 via a bracket 23 fixed to the horizontal connecting member 21a of the backrest 16. A movable piece 25 pivotally supported by a horizontal support shaft 24 in the width direction of the backrest 16, a spring 26 for projecting the movable piece 25 to the side where the support 17 is provided, and a spring 26. An actuator 28 operated by a cam 27 projecting upward from the base of the movable piece 25 indicates that the movable piece 25 has swung downward against the urging force.
and a detector (limit switch) 28 for detecting through a. The free end of the movable piece 25 is curved in a downward arc shape.

In the vicinity of the base of the support portion 17, a non-slip plate member 29 abutting against the seat seat bottom surface is fitted and fixed so as to connect the pair of right and left bar members 20a and 20b to each other.

When the vehicle front sheet 30 is conveyed by the conveying device constructed as described above, the front seat 30 is brought into contact with the seat back portion 30b against the hanger back portion 16 as shown by a virtual line in the figure. Then, the seat 30a is transferred onto the hanger 8 so that the seat 30a is placed on the hanger support 17. At this time, the hanger support portion 17 is fitted between a pair of left and right slide rails 30c and 30d provided on the bottom surface of the seat portion 30a. Of course, the seat back 30b
Is fitted between the pair of left and right positioning arms 18a, 18b of the hanger backrest 16. In addition, the upper edge of the anti-slip plate member 29 abuts against the bottom surface near the rear end of the seat portion 30a to prevent the front seat 30 from sliding on the hanger support portion 17 in the falling direction.

When the front seat 30 is transferred onto the hanger 8 for supporting the sheet as described above, the movable piece 25 of the sheet detecting means 19 on the hanger 8 side is pushed by the rear surface near the lower end of the seat back portion 30b. Spring 2
6, the swing movement is detected by the detector 28 via the cam 27 and the actuator 28a. 8 can be automatically checked.

[0013]

As described above, according to the vehicle seat conveying apparatus of the present invention, an automobile front seat comprising a seat and a backrest and having a pair of right and left slide rails on the bottom of the seat is provided. The seat is placed on the hanger by placing the backrest in contact with the hanger backrest and placing the portion of the seat between the slide rails on the hanger support, thereby transferring the sheet onto the hanger. It can be stably supported without using a dedicated pallet or the like, and can be transferred by the transfer movable body (the train 1 in the embodiment). Moreover, since the sheet placed on the hanger can be reliably detected by the movable piece attached to the hanger and the detector, the completion of sheet transfer onto the hanger is automatically detected by the detector. Can be detected automatically, and the work can be automated.

In particular, when a pair of left and right positioning arms into which the seat backrest is fitted protrude from the backrest of the hanger, it is possible to more reliably prevent the seat from dropping laterally from above the hanger. Can be done.
