a is formed, and the outer peripheral surface of the roller 45 is brought into pressure contact with these recesses 43a.

That is, when the inclination angle of the traveling vehicle 10 is changed in accordance with the movement from a horizontal track to a vertical track, which will be described later,
The handling means 35 rotates with respect to the case 41 of the horizontal maintaining mechanism 40 according to the inclination angle, whereby the load is maintained in a horizontal state, and the traveling carriage 10 travels on a horizontal or vertical track. At this time, the roller 45 is fitted into the recess 43a of the plate member 43, so that unnecessary shaking of the handling means 35 during traveling is prevented.

As shown in FIGS. 9 and 10, the rail 1 has a vertical track portion (vertical track portion) connected to a horizontal track portion (a horizontal track portion extending in the horizontal direction or a direction close to the horizontal track portion) via an R track portion. Or a vertical track portion extending in a direction close to this, and the R track portion and the vertical track portion are formed in the same sectional shape as the horizontal track portion, and the rail portion extends from the R track portion to the vertical track portion. The pinion 15 connected to the drive roller 13 is provided in the groove portion 4b of 3b.
A rack 37 capable of meshing with is attached.

Next, the operation of the monorail machine carrier will be described.

According to the monorail transporting apparatus constructed as described above, the luggage N is loaded on the handling means 35, and the traveling carriage 10 travels along the rail 1 in this state to transport the luggage N. Be seen. At this time, in the traveling carriage 10, the driving roller 13 rolls on the rail portion 3b of the rail 1 by driving the motor 12, and the rotational driving force of the driving roller 13, that is, the driving roller 13 for the rail portion 3b. The traveling carriage 10 travels along the rail 1 due to the frictional force.

Further, according to the above-mentioned monorail machine carrier, the traveling carriage 10 is caused to travel on the vertical track so that the load N
It is also possible to transport. That is, the traveling carriage 10
Runs along the rail 1 and approaches the R track portion from the horizontal track portion of the rail 1, the pinion 15 equipped on the traveling carriage 10 is rotated while meshing with the rack 37 provided on the rail 1, Due to the meshing action of the pinion 15 and the rack 37, the traveling carriage 10 can travel from the horizontal track portion to the vertical track portion of the rail 1 as shown in FIG.

When the traveling carriage 10 travels from the horizontal track portion to the vertical track portion as described above, the handling means 35 is rotated in accordance with the inclination angle of the traveling carriage 10 so that the luggage N is loaded. Maintained horizontal,
As a result, the cargo N is properly transported.

Further, according to the monorail transfer device of the above-described embodiment, as described above, the diameter of the drive roller 13 and the pitch circle diameter of the pinion 15 are configured to be the same, and the pinion 15 and the drive roller 13 are formed. Since they are integrally rotated at the same speed, smooth traveling of the traveling carriage 10 is achieved not only when the traveling carriage 10 travels from the horizontal track portion to the R track portion but also in the vertical track portion. That is, in the above-mentioned monorail type conveying device, a structure in which the diameter of the drive roller and the pitch circle diameter of the pinion are different is conceivable, but in this case, a slip occurs between the drive roller and the rail portion, and therefore, Although it causes noise and vibration, this is not the case in the above embodiment. Moreover, if slip frequently occurs between the drive roller and the rail portion, the wear of the drive roller is promoted, the life of the drive roller is shortened, and abrasion dust or the like is generated. In this case, since there is no slip between the drive roller and the rail portion, there is no possibility of causing such an inconvenience.

In the traveling carriage 10, when the driving roller 13 rotates as described above, the auxiliary roller 14 also rotates in conjunction with this, but between the auxiliary roller 14 and the rail portion 3a of the rail 1. Since the minute gap is secured as described above, the rotational driving force of the auxiliary roller 14 does not act on the rail portion 3a. Even if the auxiliary roller 14 and the rail portion 3a come into contact with each other, and the rotational driving force of the auxiliary roller 14 acts on the rail portion 3a, the auxiliary roller 14 moves with respect to the rail portion 3a. Since it is rotating in the direction of moving the vehicle and is rotating at the same speed as the drive roller 13 as described above, there is no influence such as hindering the traveling of the traveling carriage 10.

In the above description, the case where the luggage N is conveyed while the traveling carriage 10 travels on the rail 1 in a suspended state as shown in FIG. 1 has been described. As shown in FIG. 11, it is also possible to transport the luggage N while the traveling carriage 10 is traveling on the rail 1 in the back state.

In this case, although not shown in detail,
As compared with the case of the above-mentioned suspended state, the traveling carriage 10 is mounted on the rail 1 in a state of being turned upside down. Then, under such a rear surface state of the traveling carriage 10, the support roller 17 and the auxiliary roller 14 are grounded to the lower rail portion 3b by the own weight of the traveling carriage 10 between the rail portions 3a and 3b of the rail 1. , The drive roller 13 and the upper rail portion 3
A minute gap is secured between the a and the installation surface. Further, as shown in the figure, the handling means 35 is arranged above the traveling carriage 10.

At the time of transportation, the handling means 3
The luggage N is loaded on the vehicle 5, and in this state, the traveling carriage 10 travels along the rail 1 to carry the luggage N. At this time, in the traveling carriage 10, the motor 12
The driving roller 13 is rotated by the driving of the driving roller, and the rotational driving force is transmitted to the auxiliary roller 14 via the pinions 15 and 16. And the auxiliary roller 14 is the rail 1
Rolling on the rail portion 3b, and the rotational driving force of the auxiliary roller 14 acts on the rail portion 3b.
0 runs along the rail 1.

Further, according to the above-mentioned monorail type transporting device, even when the traveling carriage 10 is vertically driven from the rear surface state, as in the case of vertically traveling from the suspended state,
Luggage N while traveling the traveling carriage 10 along a vertical track
Can be transported.

In this case, as shown in FIGS. 12 and 13, the pinion 16 connected to the auxiliary roller 14 is fitted in the groove 4b of the rail portion 3b from the R track portion of the rail 1 to the vertical track portion. A rack 38 that can be engaged with is attached. Then, when the traveling carriage 10 approaches the R track portion from the horizontal track portion of the rail 1 during traveling, the pinion 16 is rotated while meshing with the rack 38 of the rail 1,
As a result, the traveling carriage 10 can travel from the horizontal track portion to the vertical track portion of the rail 1 as shown in FIG.

Even when the traveling carriage 10 is traveling in the back state in this way, the horizontal state of the luggage N loaded on the handling means 35 is maintained by the horizontal maintaining mechanism 40. Further, as described above, the diameter of the auxiliary roller 14 and the pitch circle diameter of the pinion 16 are the same, and the pinion 16 and the auxiliary roller 14 are integrally rotated at the same speed. There is no slip, and the traveling carriage 10 is the same as when traveling in a suspended state.
The smooth running of is achieved.

Although the drive roller 13 is also rotated while the traveling vehicle 10 is traveling, when the traveling vehicle 10 is traveling on the back side, as described above, a minute gap is formed between the driving roller 13 and the rail portion 3a. Since it is secured, the drive roller 13
The rotational driving force of does not act on the rail portion 3a. Further, even if the drive roller 13 and the rail portion 3a come into contact with each other, the drive roller 13 moves with respect to the rail portion 3a.
It is rotated in the direction of 0, and the auxiliary roller 14
Since it is rotated at the same speed as above, there is no effect such as hindering the traveling of the traveling vehicle 10 as in the case where the traveling vehicle 10 is traveling in a suspended state.

As described above, according to the above monorail type transfer device, the traveling carriage 10 is provided with the pinions 15 and 16, and the racks 37 and 38 are provided at the required portions (vertical track portion and R track portion) of the rail 1. As a result, vertical running is possible in addition to horizontal running. further,
In the present embodiment, the same traveling carriage 10 can be used to carry the traveling carriage 10 in a suspended state with respect to the rail 1 and the conveying manner in which the traveling carriage 10 is caused to travel in the rear state. Therefore, the traveling carriage 10 can be used in common even when it is necessary to change the transport mode. Moreover, the pinions 15 and 16 and the rack 37,
With 38, the traveling carriage 10 can be caused to travel vertically regardless of whether it is in the suspended state or in the rear state, and the functionality of the monorail type transport device is enhanced.

In particular, in the structure of the above monorail type conveying device, the rail portions 3a and 3b are provided with the groove portions 4a and 4b, respectively, and in the horizontal track portion, the pinions 15 and 16 are released into the groove portions 4a and 4b, and the vertical track portion is provided. Then, the groove portions 4a, 4
Since the racks 37 and 38 are attached to b so that the pinions 15 and 16 mesh with each other, the pinions 15 and 16 can be made to function only at a necessary portion of the transfer track with a simple configuration. Therefore, by appropriately attaching / detaching the racks 37, 38 to / from the rail 1, it is possible to easily cope with a change in the transport route.

By the way, according to the above-mentioned monorail type transporting device, for example, a loop-shaped transport track is formed over the ceiling part and the above-ground part, and the luggage is carried while traveling the traveling carriage 10 along the transport track. It is possible to configure a transport system that transports. FIG. 14 shows an example of such a transport system, and this transport system will be described below.

In this embodiment, since the transportation track has a loop shape, the rail portion of the rail 1 is the rail portion 3a on the outer peripheral side and the rail portion on the inner peripheral side is the rail portion as shown in FIG. Part 3b
And

In this transfer system 50, the traveling carriage 10 travels in a suspended state on the horizontal track A, and while traveling around the transfer track clockwise, from the station 51A to the station 51B or from the station 51B to the station. It is designed to carry luggage to 51A.

Further, in such a structure, if the above-mentioned pinion is provided integrally with the drive wheel and the pitch circle diameter of the pinion and the diameter of the drive wheel are formed to have the same size,
In the section where the pinion meshes with the rack, the occurrence of slip on the installation surface of the drive wheel is suppressed.

Furthermore, if a groove for rack mounting is formed on the installation surface of the drive wheel in the monorail track in correspondence with the pinion along the traveling direction, for example,
In the horizontal track part, the pinion is allowed to escape into the groove part, and in the vertical track part, the rack can be attached to the groove part so that the pinion can be engaged. With a simple structure, the pinion can function only at the necessary parts of the transport path. .
