Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a load conveyance facility comprising a rail device with an open bottom and a self-propelled cart guided by the rail device.

Normally, in the above-mentioned cargo transport equipment, the rail device is installed near the ceiling, so at the station where the cargo is loaded and unloaded onto the self-propelled trolley, the self-propelled trolley is moved up to the loading/unloading level. The rail device must be brought down to position it.

This requires the use of a curved rail device that is not easy to manufacture, and also increases the cost of the equipment in terms of accessories such as power supply L/- rails.

In order to solve this problem, it may be possible to provide a transfer device for each station, but this is not an advantageous solution since there are many stations.

The present invention proposes a load conveying equipment that can solve the above problems, and an embodiment thereof will be described below based on the drawings.

Reference numeral 1 denotes a rail device having a C-shaped cross section, which is installed with its open portion as the lower part, and forms a downward travel guide surface 2, a pair of left and right upward travel guide surfaces 3, and a lateral movement restriction guide surface 4.

Two power supply rails 5 and 1 are provided on the downward travel guide surface 2.
A signal rail 6 is installed along the length of the rail, and racks (not shown) are installed in the vertical or inclined path.

Reference numeral 7 denotes a self-propelled trolley that can travel on a fixed path 8 guided by the L-knoll device 1, and includes a drive unit main body 9 and a downward traveling guide surface 2 attached to one end side of the main body 9 via an axle 10. An idling wheel 11 that can be moved on the top, an idling wheel 13 that is attached to the other end of the main body 9 via an axle 12 and that can be transferred on the upward travel guide surface 3, and an idling wheel 13 that is attached to both axles 10, 12. In addition, a lateral movement regulating wheel 14 that can be moved on the lateral movement regulating guide surface 4, a motor 15 attached to the lower part of the other end of the main body, and a drive shaft 17 that is interlocked with this motor 15 via a speed reduction device 16. A friction drive wheel 18 attached to the drive shaft 17 and movable on the downward travel guide surface 2, a pinion 19 attached to the drive shaft 17 and able to engage with the rack, and a friction drive wheel 18 that slides on the power supply rail 5. Contactable current collector 2
0, and a current collector 21 that can be slidably contacted with the signal rail 6.

Furthermore, a box-shaped case 22 is attached to the lower part of the main body 9, and this case 22 has two sets of pantograph mechanisms 23A and 2.
Hanger 24 is suspended via 3B.

That is, two sets of pantograph mechanisms 23A and 23B are arranged as an example, and the upper ends of the links are attached to a common roller 26 guided by a pair of front and rear guides 25 attached to the case 22, and the lower ends of the links are attached to the hanger 24. It is attached to rollers 28A and 28B, respectively, which are guided by a pair of front and rear guides 27A and 27B attached to the upper end of the roller.

and the first intersection [roller 3 attached to the 0 connecting pin 29]
0 is engaged with a guide 31 hanging down from the bottom surface of the case 22.

Inside the case 22, both pantograph mechanisms 23A,
A drive device 32 is provided which simultaneously operates 23B.

That is, the drive device 32 includes a motor 33 attached to the case 22 and a small diameter gear 3 attached to the output shaft of this motor 33.
4, a large-diameter gear 35 that constantly meshes with this small-diameter gear 34, and a rotating link 36 fixed to the shaft of this large-diameter gear 35,
Lifting link 3 whose one end is connected to the free end of the rotating link 36 via a pin 37 and whose lower end is connected to the connecting pin 29
It consists of 8.

The hanger 24 is formed into a box shape with an open top and other sides.

The case 22 is provided with a conveyed object holding plate 39 that can be raised and lowered above the hanger 24 and is elastically biased downward.

That is, a plurality of tips 40 erected from the upper surface of the conveyed object holding plate 39 are made to protrude into the case 22 through the through holes 41, a stopper 42 is attached to the upper end thereof, and the case 2
A coil spring 43 is provided between the carrier 2 and the conveyed object holding plate 39.

44 indicates a conveyed object. The self-propelled trolley 7 is driven by a motor 15.
This is possible on a constant path 8 by transmitting the rotational force to the friction drive wheel 18 via the reduction gear device 16 and the drive shaft 17, and causing the friction drive wheel 18 to roll under pressure on the downward traveling guide surface 2.

Furthermore, the traveling is carried out with the idle wheels 1 against the downward traveling guide surface 2.
1 transfer and idle wheels 13 relative to the upward travel guide surface 3
and the transfer of the lateral movement regulating wheels 14 to the lateral movement regulating guide cylinder 4, the movement is carried out on a fixed path 8 such as horizontal, inclined, and vertical without wobbling or rattling. The conveyed object 44 can be stably conveyed.

In such cargo transport equipment, the cargo 44 is loaded and unloaded in the following manner.

That is, by starting the motor 33, both pantograph mechanisms 2
3A.

23B is expanded, thereby lowering the hanger 24 as shown in phantom lines.

As a result, the transported articles 44 can be loaded and unloaded as shown by arrow A in FIG.

By contracting the pantograph mechanisms 23A and 23B and raising the hanger 24 as shown by the solid line, the loaded articles 44 can be simultaneously raised and their upper surfaces can be brought into contact with the article holding plate 39.

At that time, the holding plate 39 moves upward against the coil spring 43,
Therefore, during transportation, the conveyed object 44 is held between the holding plate 39 and the case 22 by the elastic force of the coil spring 43, and can be prevented from falling.

As described above, according to the present invention, it is possible to load and unload objects onto the hanger while keeping the level of the rail device constant, and thus the whole can be provided at low cost.

Furthermore, since the conveyed object is elastically held between the hanger and the conveyed object holding plate, it is possible to prevent it from falling during conveyance.

Moreover, by adopting two sets of pantograph mechanisms,
Shaking of the hanger can be completely prevented.
