Description

[Detailed Description of the Invention] The present invention relates to a transportation facility comprising a rail device and a self-propelled cart guided by the rail device.

1 to 4 show conventional examples. That is, in FIGS. 1 and 2, 1 is a first rail device forming a first traveling route 2, and 3 is a second rail device forming a second traveling route 4. These rail devices 1 and 3 are Routes 2 and 4 are arranged in parallel in opposite directions. Reference numeral 5 indicates a self-propelled trolley capable of traveling in forward and reverse directions on both travel routes 2 and 4. Reference numeral 6 denotes a trolley transfer device that moves the trolley 5 between both running routes 2 and 4 that are arranged in parallel, and that moves a pair of integrated movable rails 7 and 8 and these movable rails 7 and 8 back and forth in the lateral direction. It is composed of a driving section 9. 10 is one movable rail 7 corresponding to the first traveling route 2
The reading device installed in the figure is shown.

According to the conventional conveyance equipment described above, as shown in FIG.
It is read by the reading device 10 at the movable rail 7 section, and if there is no need to transfer, the vehicle travels on the first travel route 2 A as it is. Moreover, the truck 5 on the second traveling route 4 continues traveling B. If transfer is necessary based on the reading by the reading device 10 on the movable rail 7 section described above, the drive section 9 is activated to move both movable rails 7 and 8 laterally, as shown in FIG. It is connected to the second rail device 3. This makes transfer travel C possible. According to this format, the second
Transfer travel D from the travel route 4 to the first travel route 2 becomes impossible. In order to solve this problem, conventionally, as shown in FIG. 4, another trolley transfer device 6A is provided which has a reading device 10A corresponding to the second traveling route 4. This enables the transfer run D to 2.
However, this type requires two cart transfer devices 6, 6A, which increases the equipment cost.

Therefore, the present invention proposes a conveyance facility that can inexpensively transfer carts between the two travel routes, and one embodiment thereof will be described below with reference to FIGS. 5 to 9.

Figures 5 and 6 show the conventional example (Figures 1 and 2).
Items with the same reference numerals as in the figure) indicate the same or almost the same components. That is, 1 is a first rail device, 2 is a first traveling route, 3 is a second rail device, 4 is a second traveling route, 5 is a self-propelled trolley, 6 is a trolley transfer device,
7 and 8 are movable rails, and 9 is a drive section. In the present invention, only one trolley transfer device 6 is provided, and the movable rail 7 is provided with a first reading device 11 corresponding to the first traveling route 2. And a second reading device 12 corresponding to the second travel route 4
However, at the top of the trolley transfer device 6, a second
It is arranged in the rail device 3.

According to the conventional conveyance equipment described above, as shown in FIG.
The first reading device 11 is located at the movable rail 7 section.
If there is no need to transfer, the vehicle continues to travel along the first travel route 2 A. Also the second
The self-propelled trolley 5 traveling on the traveling route 4 is read by the second reading device 12 at the top of the trolley transfer device 6, and if transfer is not necessary, the self-propelled trolley 5 travels on the second traveling route B as it is. If transfer is necessary based on the reading by the first reading device 11 on the movable rail 7 section described above, the drive section 9 operates as shown in FIG.
8 moves laterally to connect the movable rail 7 supporting the self-propelled cart 5 to the second rail device 3. This makes transfer travel C possible. Further, if transfer is necessary based on the reading by the second reading device 12, the drive unit 9 is activated by the reading signal, and the empty movable rail 7 is connected to the second rail device 3 as shown in FIG. let As a result, the self-propelled cart 5 enters the movable rail 7, and by returning the movable rail 7 to its original position, it becomes possible to transfer and travel D as shown in FIG.

According to the present invention as described above, the transfer of carriages between the two travel routes can be reliably performed by using a single carriage transfer device, and structurally, since only one reading device is added, it can be provided at a lower cost than the conventional structure in which a separate carriage transfer device is added.
