The driving roller 13 and the auxiliary roller 14
Each have a drive shaft 13a and a drive shaft 14a protruding toward the side of the rail 1 (right side in FIG. 3). These drive shafts 13a and 14a are mounted on the traveling carriage 10.
The frame 11 is rotatably supported by bearings.

Pinions 15 and 16 are inserted through the drive shafts 13a and 14a, respectively, and are integrally connected to the drive roller 13 and the auxiliary roller 14. These pinions 15 and 16 have a pitch circle diameter of the drive roller 1 respectively.
3 and the auxiliary roller 14 are formed to have the same size as each other, and they are meshed with each other while being coupled to the rollers 13 and 14. As a result, when the drive roller 13 is rotated, the auxiliary roller 14 is interlocked and rotates at the same peripheral speed as the drive roller 13 and in the opposite direction to the drive roller 13. Also, each of the above pinion 1
5 and 16 are arranged integrally with the drive rollers 13 and 14 between the rail portions 3a and 3b of the rail 1. As shown in FIG. 5, the lower outer periphery of the pinion 15 is the rail portion 3b.
The outer periphery of the upper portion of the pinion 16 protrudes into the groove portion 4a of the rail portion 3a.

On the other hand, the motor 12 is arranged below the drive roller 13 and the like and directly below the rail 1. The motor 12 is a frame 1 of the traveling carriage 10.
1 and its output shaft is connected to the shaft body 20 via a gear or the like (not shown).

The shaft body 20 is supported by a frame 11 of the traveling carriage 10 via bearings so as to be rotatable about a vertical axis, and has a hypoid gear 21 at the upper end thereof. Meshes with the hypoid gear 22 fixed to the drive shaft 13a.

A clamp 29 having a wedge-shaped tip is attached to the actuating shaft of the electromagnetic solenoid 28. When the electromagnetic solenoid 28 is in an excited state, the clamp 29 is integrated with the actuating shaft in the locking member 26. On the other hand, when the electromagnetic solenoid 28 is in the non-excited state, the clamp 2
9 is retracted into the frame of the electromagnetic solenoid 28.

In the brake mechanism 24 having such a structure, when the electromagnetic solenoid 28 is not excited, the clamp 29 is retracted from between the pieces 27b of the arms 27, so that the arms 30 are biased by the springs 30. Each of the claw portions 27a of the drive shaft 1 meshes with the gear 25, whereby the drive shaft 1
The rotation of 3a is blocked. On the other hand, when the electromagnetic solenoid 28 is energized, as shown in FIG. 8, the clamp 29 projects and the tip of the clamp 29 projects between the pieces 27b of the arms 27 of the locking member 26. The claw portion 27a is held at a position separated from the gear 25, and the rotation of the drive shaft 13a is allowed. That is, the brake mechanism 24 is activated when the electromagnetic solenoid 28 is not excited, and the brake mechanism 24 is deactivated when the electromagnetic solenoid 28 is excited.

Further, the traveling vehicle 10 is provided with a control box 31 accommodating various control devices for controlling the traveling vehicle 10 in an integrated manner. As shown in FIG. 3, the control box 31 has a frame 11 of the traveling carriage 10 at a position directly below the rail 1 and is substantially symmetrical to the motor 12 by sandwiching a vertical axis passing through the rail 1. Installed on. That is, since the motor 12 and the control box 31 are both relatively heavy members in the traveling carriage 10, by arranging the rails 1 in such a manner that they are symmetrically arranged,
The weight balance of the entire traveling vehicle 10 can be suitably secured.

Further, a mark sensor 34 is attached to the tip of the traveling carriage 10 so that the rail 1 can be operated during traveling.
A mark as running information on the lower surface of the control box 31 is detected by the mark sensor 34 and output to the control device in the control box 31.

The handling means 35 is connected to the lower portion of the traveling carriage 10 via a horizontal maintaining mechanism 40. Although the specific structure of the handling means 35 is not limited by the present invention, in the present embodiment, a box-shaped handling having an opening portion for loading and unloading of cargo on the side (left side in FIG. 2) is provided. Means 35 are applied, which are connected to the lower end of the horizontal holding mechanism 40.

As shown in FIGS. 6 and 7, the horizontal maintaining mechanism 40 has a case 41 joined to the lower end of the frame 11 of the traveling carriage 10 and extending downward. Below the case 41, a plate member 43 having a substantially cylindrical shape is provided.
A support shaft 42 having a shaft is rotatably supported via a bearing or the like. The end of the support shaft 42 is attached to the case 41.
Is projected to the side (left in FIG. 7), and the handling means 35 is connected to this projecting portion so as to be rotatable with respect to the case 41.

Inside the case 41, an arm member 44 having a roller 45 is swingably disposed above the plate member 43, and an absorber 46 is further provided above the arm member 44. It is arranged. The absorber 46 constantly presses the arm member 44 downward, and by doing so, the roller 45 is brought into pressure contact with the outer peripheral surface of the plate member 43. Further, as shown in FIG. 6, on the outer peripheral surface of the plate member 43, arcuate recesses 43a are formed at predetermined intervals (90 ° intervals in the illustrated example) in the circumferential direction, and the roller 45 is formed. The outer peripheral surface of is pressed against 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.

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 when the motor 12 is driven, and the rotational force of the driving roller 13 acts on the rail portion 3a of the rail 1 to travel. The dolly 10 travels along the rail 1.

Further, according to the monorail machine transfer device, it is possible to transfer the luggage N while the traveling carriage 10 is traveling on the vertical track. In this case, as shown in FIGS. 9 and 10, a rack capable of meshing with the pinion 15 connected to the drive roller 13 in the groove portion 4b of the rail portion 3b from the R orbit portion of the rail 1 to the vertical orbit portion. 37 is attached.

That is, when the traveling carriage 10 travels along the rail 1 and approaches the R track portion from the horizontal track portion of the rail 1, the pinion 15 is rotated while meshing with the rack 37 of the rail 1, and the pinion 15 By the meshing action of the rack 37 and the rack 37, the traveling carriage 10 travels 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 in this way, the handling means 35 is rotated in accordance with the inclination angle of the traveling carriage 10 to horizontally move the load N. The state is maintained, whereby the parcel N is properly transported.

Further, in the monorail transfer device of the above embodiment, the diameter of the drive roller 13 and the pitch circle diameter of the pinion 15 are the same as described above,
Moreover, since the pinion 15 rotates at the same peripheral speed as the drive roller 13, when the traveling carriage 10 travels from the horizontal track portion to the R track portion, the drive roller 13 and the rail 1 are not only moved in the vertical track portion. Therefore, the traveling carriage 10 travels smoothly, noise generated during traveling is reduced, and wear of the drive roller 13 is prevented.

By the way, in the traveling carriage 10,
When the drive roller 13 is rotated as described above, the auxiliary roller 14 is rotated in synchronization with the rotation of the drive roller 13.
Since a minute gap is secured between the rail 4 and the rail portion 3a of the rail 1 as described above, the auxiliary roller 1
The rotational force of 4 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 force of the auxiliary roller 14 acts on the rail portion 3a, the auxiliary roller 14 moves the traveling carriage 10 against the rail portion 3a. Since it is rotating in the advancing direction and is rotating at the same peripheral speed as the drive roller 13 as described above, there is no influence such as hindering the traveling of the traveling carriage 10.

The example in which the luggage N is transported while the traveling carriage 10 is traveling in a suspended state with respect to the rail 1 as shown in FIG. 1 has been described above. As shown, 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. Under such a rear surface state of the traveling carriage 10, the supporting roller 17 and the auxiliary roller 14 are installed on the lower rail portion 3b by their own weight between the rail portions 3a and 3b of the rail 1, and the driving roller 13 is also provided. A small gap is secured between the upper surface and the installation surface of the upper rail portion 3a, and the handling means 35
Are 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
The rolling carriage rolls on the rail portion 3b, and the rotational force of the auxiliary roller 14 acts on the rail portion 3b, whereby the traveling carriage 10 travels along the rail 1.

Further, even when the traveling carriage 10 is vertically driven from the rear surface state, it is possible to carry the load N while traveling the traveling carriage 10 along the vertical track, as in the case where the traveling carriage 10 is vertically traveled. Is.

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 travels from the horizontal track portion to the vertical track portion of the rail 1 as shown in FIG.

Even when the traveling carriage 10 travels in the back state in this way, the cargo N loaded on the handling means 35 is maintained in the horizontal state 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 rotated at the same peripheral speed, so that the distance between the drive roller 13 and the rail 1 is increased. There is almost no occurrence of slip and the traveling vehicle 10 travels smoothly.

While the traveling carriage 10 is traveling, the drive roller 13 also rotates, but as described above, the drive roller 1
Since a minute gap is secured between the rail 3 and the rail portion 3a, the rotational force of the drive roller 13 does not act on the rail portion 3a. Note that the driving roller 13 and the rail portion 3a
Even when comes into contact with, the driving roller 13 is rotated in the direction in which the traveling carriage 10 is advanced with respect to the rail portion 3a, and is further rotated at the same peripheral speed as the auxiliary roller 14, so that the traveling carriage 10 is suspended. As in the case where the vehicle is traveled in, there is no effect such as hindering the traveling of the traveling vehicle 10.

As described above, according to the monorail type transporting apparatus of the above-described embodiment, the transporting mode in which the traveling vehicle 10 is suspended from the rail 1 and the transportation mode in which the traveling vehicle 10 is traveling in the rear state are the same traveling vehicle. 10 can be used. Therefore, even if it is necessary to change the transportation mode by changing the transportation object, the functionality of the monorail transportation device can be enhanced by using the traveling carriage 10 in common.

In particular, in the traveling carriage 10, the motor 12 and the control box 31 are below the rail 1 (when the traveling carriage 10 is in a suspended state).
Since the mounting portion on the rail 1 has a compact structure, the motor 12 and the control box 31 may interfere with traveling when traveling on a turning track (curve). Without
Therefore, the traveling carriage 10 can be caused to travel along a turning track having a smaller turning diameter. Moreover, as the above monorail track, the rail portion 3 is provided at the upper and lower ends of the rail-constituting wall 2.
The rail 1 having an I-shaped cross section including a and 3b is applied, and the driving roller 13 and the auxiliary roller 14 of the traveling carriage 10 are applied.
Since the rails are projected between the rail portions 3a and 3b of the rail 1, there is no portion of the traveling carriage 10 that projects above (or below) the rail 1, so that the traveling carriage can hold the rails. Compared with the conventional device configured, the rail 1 can be installed at a position closer to the ceiling or the ground and the traveling carriage 10 can be driven.

That is, according to the above-mentioned monorail type conveying device, the traveling carriage 10 is made to travel in a place closer to the ceiling portion or the above-ground portion, or has a relatively small diameter, as compared with the conventional monorail type conveying device of this type. There is a feature that the traveling performance of the traveling vehicle 10 is improved in that it can travel along a turning track. Therefore, the degree of freedom in designing the transportation track is increased, and it is possible to provide an optimal transportation track according to the layout of the building or a transportation track that can fully utilize the work space of a factory or the like.

Further, in the traveling carriage 10, as described above, the motor 12 and the control box 31 which are relatively heavy are arranged symmetrically with respect to the vertical axis passing through the rail 1, whereby the traveling carriage 10 as a whole. Since the weight balance of the vehicle is properly maintained, it is possible to suppress the occurrence of vibration and noise at the time of traveling due to the imbalance of weight, overload on the drive mechanism, and unnecessary shake of the handling means. You can

Further, since the trolley wire 6 and the drive roller 13 and the auxiliary roller 14 of the traveling carriage 10 are arranged on different sides with the rail-constituting wall 2 of the rail 1 interposed therebetween, they are different from the trolley wire 6. Dust (for example, carbon powder) generated by the sliding contact of the current collector 32 does not adhere to the drive roller 13 or the like, and therefore, the occurrence of slip due to the dust adhering to the drive roller or the like is prevented in advance. There is also an advantage that it can be done.

By the way, according to the above monorail type transfer device, for example, a loop-shaped transfer 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 transfer 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 the figure, the transfer track of the transfer system 50 is composed of the rail 1 described above. By installing this rail 1 over the ground and ceiling of a factory or the like, a loop-shaped transfer track is formed. It is configured. More specifically, a horizontal orbit A on the ceiling, R orbits B and H before and after it, a horizontal orbit E on the ground, R orbits D and F before and after it, and vertical orbits C and G form a transport orbit. There is. The horizontal tracks A and E are provided with stations 51A and 51B for loading and unloading cargo.

Although not shown in the drawings, in the rail 1, rail portions 3 are provided at the portions of the R tracks B and H and the vertical track C.
A rack 37 is attached to the groove portion 4b of b, and a rack 38 is attached to the groove portions 4a of the rail portions 3a at the portions of the R tracks D and F and the vertical track G, respectively. 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.

Here, the traveling of the traveling carriage 10 in the transport system 50 will be described in detail. In the following description, the stations 51A to 51
A case where the parcel N is transported to B will be described.

First, when loading of the luggage N onto the handling means 35 is completed at the station 51A, the traveling carriage 10 is caused to travel clockwise along the horizontal trajectory A of the transport trajectory. At this time, the traveling carriage 10 is suspended from the rail 1 as described above, and the driving roller 13 rolls on the rail portion 3b to travel along the horizontal track A. When the traveling carriage 10 reaches the R track B, the pinion 15 connected to the drive roller 13 and the rack 37 attached to the rail portion 3b rotate while meshing with each other, thereby moving from the ceiling portion to the ground portion. The traveling carriage 10 travels on the R track B and the vertical track C.

In this way, the traveling carriage 10 is on the R track D on the ground.
When the vehicle reaches, the traveling carriage 10 is turned upside down with respect to the rail 1, and the pinion 16 connected to the auxiliary roller 14 rotates while meshing with the rack 38 of the rail portion 3a. The dolly 10 runs. Then, when the traveling carriage 10 reaches the horizontal track E, the auxiliary roller 14 rolls on the rail portion 3a of the rail 1, so that the traveling carriage 10 travels along the horizontal track E in the back state.

When the traveling carriage 10 reaches the station 51B, the luggage N is unloaded here, and then the traveling carriage 10 is again made to travel in the clockwise direction along the horizontal orbit E. Then, when the traveling carriage 10 reaches the R track F, the pinion 16 coupled to the auxiliary roller 14 rotates while meshing with the rack 38 of the rail portion 3a, whereby the traveling carriage 10 moves from the ground portion to the ceiling portion. Runs on an R orbit F and a vertical orbit G.

Then, the traveling carriage 10 has an R track H on the ceiling.
When it reaches, the traveling carriage 10 is turned upside down with respect to the rail 1, and the pinion 15 connected to the drive roller 13 rotates while meshing with the rack 37 of the rail portion 3b. 10 runs. Then, when the traveling carriage 10 reaches the horizontal track A, the drive roller 13 rolls on the rail portion 3b of the rail 1, whereby the traveling carriage 10 travels along the horizontal track A and reaches the station 51A. .

Although not described in detail, the load N loaded on the handling means 35 during the traveling of the traveling vehicle 10 along the transportation track as described above, as shown in FIG. The horizontal maintaining mechanism 40 maintains the horizontal state.

As described above, according to the transport system 50, since the traveling carriage 10 travels along the loop-shaped transport track extending from the ceiling portion to the ground portion, for example, the transport system 50 is assembled into a machine. If it is applied to a line or the like, it becomes possible to carry out a series of work transfer from the loading, processing, and unloading of the work with a single traveling carriage 10.

Moreover, in the above-described transport system 50, it is not necessary to switch the rotation direction of the drive roller 13 of the traveling carriage 10 while the traveling carriage 10 travels along the loop-shaped conveying path in this way. , Trolley 10
Can be controlled extremely easily, and the traveling carriage 10 can be continuously and smoothly traveled along the transportation track.

[0068]

As described above, according to the monorail type transport apparatus of the present invention, the drive motor and the controller mounted on the traveling carriage are provided under the drive shafts having the drive wheels, respectively, and the monorail track is provided. Since it is arranged so as to be almost symmetrical with the axis passing through it, it is possible to drive the traveling carriage along a turning track (curve) with a relatively small diameter and to maintain a good weight balance of the entire traveling carriage. As a result, the traveling performance of the traveling vehicle is improved.

Further, in such a structure, a monorail track having an I-shaped cross section having rail portions projecting laterally at the upper and lower ends of the monorail constituting wall is applied, and the drive wheels of the traveling carriage are monorail tracks. If it is configured to be installed in the rail part in a state that it rushes between the upper and lower rail parts, the part of the traveling carriage that projects above the monorail becomes smaller, which allows the monorail track to be installed closer to the ceiling, The traveling carriage can be driven.

Further, if the trolley wire is arranged on the side different from the side on which the drive wheels are arranged so as to sandwich the monorail constituent wall, dust generated by sliding contact between the trolley wire and the current collector will adhere to the drive wheels. Therefore, the occurrence of slip of the traveling carriage due to the dust is prevented.
