2. Description of the Related Art Conventionally, as a conveying device having a delivery rail, as shown in FIG. 11 of JP-A-61-295994, the delivery rail is arranged below a rail-shaped support member, An upper trolley having a drive device is fixed to upper portions on both sides in the longitudinal direction of the feed rail, the driving wheels of each upper trolley are mounted on the lower flanges of the support members, and the upper trolley extends in the longitudinal direction of the feed rail. At a slightly distant position, a flip-up prevention roller facing the lower surface of the support member is attached to the delivery rail, and a lower trolley supporting the luggage lifting device is provided on the delivery rail so that the lower trolley can travel freely. There is known a transport device having a.

[0003]

In the case of the conventional transfer device having the above-mentioned delivery rail, when the rail-shaped support member is a traveling rail having a curve, each upper trolley is fixed to the delivery rail and is flipped up. Since the prevention roller is fixed to the delivery rail at a position distant from the upper trolley in the longitudinal direction of the delivery rail, there is a drawback that the curved portion of the traveling rail cannot be smoothly traveled.

[0004]

In order to advantageously solve the above-mentioned problems, in a transporting apparatus having a feed rail of the present invention, the lower surface of the lower flange 2 of the traveling rail 1 is provided on both upper surfaces in the longitudinal direction, respectively. A plurality of traveling wheels 4 and 5 mounted on the upper trolley body 3 are mounted at a small interval in the longitudinal direction of the traveling rail, and a jumping prevention that opposes the lower surface of the lower flange 2 in the middle lower part of each traveling wheel 4 and 5 is placed. Rollers 6 are rotatably attached to the upper trolley body 3, and fixed to the lower part of the upper support metal fitting 8 fitted on the horizontal shaft 7 of each upper trolley body 3 and to the upper parts on both sides of the feed rail 9 in the longitudinal direction.

With the washer 29 interposed, the jump-up prevention roller 6 is arranged near the lower surface of the strip-shaped support plate 16 at the lower center of the lower flange 2 and the strip-shaped support plate 16 in the width direction.

Lower supporting metal fittings 10 are fixed by bolts 30 to an intermediate upper portion in the longitudinal direction of the feeding rail 9 and an upper portion of one end portion of the feeding rail 9, and the lower supporting metal fittings 10 and the upper portions thereof are arranged. The lower portion of each upper support metal fitting 8 is rotatably connected by a vertical axis 11 disposed in the lower center of the bounce prevention roller 6, and the upper support metal fitting 8 is connected by a bolt 31. The upper member 32 and the lower member 33 that are formed are configured.

Of the upper trolleys 17 on both sides of the feed rail 9 in the longitudinal direction, a traveling drive device 34 composed of an electric motor with a speed reducer is fixed to the upper trolley body 3 of one upper trolley 17, and the one upper trolley. The front and rear traveling wheels 4 and 5 in 17 are driven by a traveling drive device 34.

On the lower flange 35 of the delivery rail 9, a drive unit 3 for traveling comprising an electric motor with a speed reducer.
The traveling wheels of the lower trolley 13 equipped with 6 are mounted,
A luggage lifting device 12 composed of an electric chain block is suspended on the lower trolley 13, and stoppers 37 for preventing the lower trolley 13 from coming off the delivery rail 9 are provided at both ends of the delivery rail 9. It is fixed.

[0012]

According to the present invention, the upper trolley body 3 is provided on the upper surfaces of both sides of the lower flange 2 of the traveling rail 1 in the longitudinal direction at small intervals in the longitudinal direction of the traveling rail.
A plurality of traveling wheels 4 and 5 mounted on the upper trolley body 3 are rotatably mounted on the upper trolley body 3 so as to prevent the jumping-up roller 6 facing the lower surface of the lower flange 2 in the lower middle portion of the traveling wheels 4 and 5. The lower portion of the upper support metal fitting 8 fitted on the horizontal shaft 7 of each upper trolley body 3 and the lower support metal fittings 10 fixed to the upper portions on both sides of the feed rail 9 in the longitudinal direction are connected to the roller 6 for preventing the jumping up.
