Abstract

PURPOSE:To provide a conveying device for conveying a front seat for an automobile, which comprises a seat part and a back rest part and provided at the bottom of the seat part with a pair of right and left slide rails and is formed in an unstable shape as an unit body, in a state to support it directly by a hanger without using a pallet for an exclusive use in parallel. CONSTITUTION:A seat conveying device for an automobile is formed such that a hanger 8 for supporting a seat is suspended from a moving body (an electric car 1) for conveyance moving along a guide rail 2. The hanger 8 comprises an approximately vertical back rest part 16 and a support part 17 connected sideways from the lower end of the back rest part. The width of the support part is set to a value enough to support a seat part in a state to engage the bottom of a seat part 30a with a portion between a pair of right and left slide rails 30c and 30d attached to the bottom of the seat part. The back rest part 16 is provided with a moving piece 25 for detection moving in its state in contact with a seat back rest part 30b and a detector 28 to detect movement of this moving piece.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1 and FIG. 2, reference numeral 1 is a suspension type monorail electric train as a moving body for transportation, which has an appropriate height on the ceiling side. 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 roof, a linear motor 7 for propulsion having a bottom portion of the guide rail 2 as a secondary conductor, and a seat supporting member. An elevating body 9 with a hanger 8 attached to the lower side, and elevating drive means 10 for elevating the elevating body 9
The elevation drive means 10 is composed of a plurality of belts 11 for suspending the elevation body 9 and a drive pulley 12 for winding and unwinding the belts 11.

The propulsion linear motor 7 and drive pulley 1
2 to the 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 3. On both left and right sides of the elevating body 9, brackets 15 are provided which are pivotally supported by elevating guide rollers 14 which fit into fixed steady guide rails when descending at a predetermined unloading place.

The seat supporting hanger 8 has a backrest portion 16 that extends substantially vertically from one of the left and right sides of the lifting body 9.
And a support portion 17 which is continuously provided from the lower end of the backrest portion 16 to the other right and left side sides of the elevating body 9 in an obliquely upward direction,
A pair of left and right positioning arms 18a and 18b, which are provided substantially horizontally from the middle height position on both right and left sides of the backrest portion 16 to the same side as the support portion 17, and a sheet detecting means 19.
It consists of and.

More specifically, the seat supporting hanger 8 includes two bar-shaped members (steel pipes, etc.) 20a, 20b bent in a substantially U-shape and having a vertical portion at an intermediate height and a height near a lower end. Are connected and integrated by horizontal connecting members (steel pipes, etc.) 21a, 21b, and the vertical portion thereof is used as the backrest portion 16 and the lower two fork-shaped portions are used as the support portion 17, and the upper two portions are connected. The fork part of
The mounting portion 22 is attached to the bottom surface of the lifting body 9. Further, the pair of left and right rod-shaped members 21a and 21b in the backrest portion 16 includes the positioning arms 18a and 21a.
The portion to which 18b is attached is set to the maximum width, and the lower portions are deformed so as to be closer to each other in the center.
The width of the portion that becomes 6 is narrowed to a predetermined size.

The sheet detecting means 19 is mounted at a central position near the lower end of the backrest portion 16 via a bracket 23 fixed to a horizontal connecting member 21a of the backrest portion 16, and the lower end portion of the bracket 23 is attached. In addition, a movable piece 25 pivotally supported in the vertical direction by a horizontal support shaft 24 in the width direction of the backrest portion 16, a spring 26 for projecting the movable piece 25 to the side where the support portion 17 is present, and a spring 26 of the spring 26. When the movable piece 25 swings downward against the biasing force, an actuator 28 operated by a cam 27 protruding upward from the base of the movable piece 25.
It is composed of a detector (limit switch) 28 for detecting via a. The movable piece 25 has a free end curved in a downward arc shape.

In the vicinity of the base portion of the support portion 17, a slip prevention plate member 29 that abuts the bottom surface of the seat is fitted and fixed so as to connect the pair of left and right rod-shaped members 20a and 20b to each other.

When the automobile front seat 30 is conveyed by the conveying device constructed as described above, the seat back portion 30b is brought into contact with the hanger backrest portion 16 as shown by the phantom line in the figure. Then, the seat seat 30a is transferred onto the hanger 8 for supporting the seat so that the seat 30a is placed on the hanger support 17. At this time, the hanger support portion 17 is fitted between the pair of left and right slide rails 30c and 30d attached to the bottom surface of the seat seat portion 30a. Of course, the seat back portion 30b
Fit between the pair of left and right positioning arms 18a and 18b of the hanger backrest portion 16. Further, the upper edge of the anti-slip plate member 29 abuts on 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 seat supporting hanger 8 as described above, the movable piece 25 of the seat detecting means 19 on the hanger 8 side is pushed to the rear surface near the lower end of the seat back portion 30b. Spring 2
6 swings downward against 6 and this swinging motion is detected by the detector 28 via the cam 27 and the actuator 28a. Therefore, the front seat 30 receives the detection signal from the detector 28 and the front seat 30 is supported by the hanger. It can be automatically checked that it has been placed on the 8.

[0013]

As described above, according to the vehicle seat conveying apparatus of the present invention, there is provided a vehicle front seat comprising a seat portion and a backrest portion and having a pair of left and right slide rails on the bottom surface of the seat portion. By bringing the backrest part into contact with the hanger backrest part and placing the part between the slide rails of the seat part on the hanger support part, by transferring the sheet onto the hanger, the seat is placed on the hanger. , And can be stably supported without being used in combination with a dedicated pallet or the like, and can be transported by the transporting movable body (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 detector automatically detects the completion of sheet transfer on the hanger. It can also be detected automatically and the work can be automated.

Particularly, when a pair of left and right positioning arms to which the seat backrest fits is provided to project on the backrest of the hanger, it is possible to more reliably prevent the seat from falling off laterally from the hanger. Can be done.
