Abstract

PURPOSE:To change a proceeding direction without changing the direction of a truck with simple constitution even in the case of being unable to secure a turning space. CONSTITUTION:Three guide pins 13-15 are fitted to the lower face of truck 10 in such a way as to be in a row in the longitudinal direction (12). At the linear travel parts 18, 19 of a guide rail 21, the truck 10 is moved rectilinearly while letting three guide pins 13-15 guide simultaneously by aggregate rails 22, 23. At the direction changing part 20 of the guide rail 21, the proceeding direction is changed by letting the respective guide pins 13-15 guide separately by three separate rails 26-28 branched from the aggregate rails 22, 23.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to bogie equipment.

[0002]

2. Description of the Related Art Generally, a bogie facility is one for guiding a bogie along a guide rail.

Then, for example, in the case of shifting the carriage from one of the straight rails parallel to each other to the other, normally, as shown in FIG. 6, the straight rails 1 and 2 parallel to each other are provided.
The curved rails 3 are connected to each other, and the carriage 4 is guided along the curved rails 3.

However, when the curved rail 3 is used, since the carriage 4 changes its direction continuously while passing through the curved rail 3, a wide turning space is provided to allow the change of the direction of the carriage 4. This is necessary, and in particular, when the carriage 4 carries a long load of several meters, there arises a problem that it is difficult to secure the turning space.

Therefore, in the case where a sufficient turning space cannot be secured, conventionally, as shown in FIG. 7, a traverse mechanism 6 capable of reciprocating between the linear rails 1 and 2 is provided between the end portions of the linear rails 1 and 2 to traverse them. The traverse carriage 7 of the mechanism 6 is used to translate the short movable rail 5 that can be selectively connected to the ends of the linear rails 1 and 2 together with the carriage 4.

In the figure, reference numeral 8 is a traverse rail of the traverse mechanism 6.

[0007]

However, when the traverse mechanism 6 is used, there is a problem that the entire bogie equipment becomes large-scale.

In view of the above situation, it is an object of the present invention to provide a bogie facility capable of changing the traveling direction without changing the direction of the bogie with a simple structure even when the turning space cannot be secured. It is what

[0009]

According to the present invention, three guide pins are mounted on the lower surface of a truck so as to be aligned in a line in the longitudinal direction of the truck, and the traveling of the truck is guided on the floor through the guide pins. 3 is provided with a guide rail, and the straight running portion of the guide rail is configured by a collective rail that simultaneously guides three guide pins, and the direction changing portion of the guide rail is individually guided by each guide pin. The present invention relates to a bogie equipment characterized in that it is composed of a book separation rail.

[0010]

The operation of the present invention is as follows.

The dolly having three guide pins mounted on the lower surface so as to be aligned in a line in the longitudinal direction of the dolly has three guide pins simultaneously guided by the collective rail in the straight running portion of the guide rail. In the direction change portion of the guide rail, the collecting rail is branched into three separation rails, and the guide rails are individually guided by the separation rails to change the traveling direction.

At this time, since the direction of the carriage can be set by adjusting the distance between the separation rails, it is possible to change the traveling direction of the carriage without changing the direction.

Further, since the traveling direction is changed by the three guide pins and the guide rails, the equipment structure is simplified.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

1 to 4 show a first embodiment of the present invention.

As shown in FIGS. 1 and 2, a trolley 10 having a plurality of traveling wheels 9 is provided at an appropriate position on the lower surface, and the trolley 1 is provided.

The floor 17 is provided with a guide rail 21 having two straight running portions 18 and 19 parallel to each other and a direction changing portion 20 connecting the straight running portions 18 and 19.

The straight running portions 18 and 19 of the guide rail 21 are connected to the three guide pins 13 to 15 of the carriage 10.
The guide rails 21 and 23 each have a slit-shaped guide groove for simultaneously guiding the guide rails, and a rail branching portion 24 and a rail joining portion 25 for branching and joining the guide rails 22 and 23 together. The conversion part 20 is composed of three separating rails 26 to 28 in which the guide pins 13 to 15 of the carriage 10 are individually guided.

Further, as shown in FIG. 3, the guide pin 14 at the center of the carriage 12 in the longitudinal direction 12 is extended downward so as to be longer than the other guide pins 13 and 15, and the driving force receiving portion 29 is provided at the extension portion. And a drive chain 31 inside
Is movably disposed, and a hook 32 for locking the driving force receiving portion 29 of the central guide pin 14 is attached to the drive chain 31, as shown in FIG.

Reference numeral 33 is a roller attached to the lower surface of the drive chain 31.

In the rail branch portion 24 provided between the one collecting rail 22 and each of the separating rails 26 to 28, the interval between the transition point 34 to each of the separating rails 26 to 28 and the branch points 35 and 36. 37 is made slightly wider than the space 16 between the guide pins 13 to 15 of the carriage 10.

The spacing 37 is defined by the separation rails 26-
28, the radii of curvature a, b, and c in the vicinity of the transition point 34 and the branch points 35 and 36 are set by setting a <b <c.

Further, a space 38 between the separation rails 26 to 28 is provided.
Is slightly narrower than the space 16 between the guide pins 13 to 15 of the carriage 10.

Further, in the rail merging portion 25 provided between each of the separating rails 26 to 28 and the other collecting rail 23, the interval between the transition point 39 and the merging points 40 and 41 from each of the separating rails 26 to 28. 42 for each separation rail 26-2
It is slightly narrower than the space 38 between the eight.

It should be noted that the spacing 42 is defined by the separation rails 26-
The radii of curvature d, e, f in the vicinity of the transition point 39 and the confluence points 40, 41 at 28 are set by setting the relationship of d>e> f.

However, the radii of curvature a, b, c and d, e, f
Due to the drawings, the difference is drawn to be larger than the actual one.

In addition, the intervals 37, 42 are provided by means other than the radius of curvature.
It is also possible to set.

Further, for convenience of explanation, one end side of the carriage 10 is referred to as an A side, and the other end side thereof is referred to as a B side.

Next, the operation will be described.

When the drive chain 31 is driven by a drive means (not shown), the drive chain 31 continuously moves within the receiving frame 30 attached to the collecting rail 22, the central separating rail 27 and the lower portion of the collecting rail 23. Will be done.

Then, the driving force receiving portion 29 formed by extending the guide pin 14 at the center of the carriage 10 is locked by the hook 32 attached to the drive chain 31, so that the carriage 10 is driven by the drive chain 31 and its Central rail 2
2. Guided and moved so as to pass through the upper portions of the central separating rail 27 and the collecting rail 23.

Then, first, in the one straight running portion 18, all the guide pins 13 to 15 are simultaneously guided by the collective rail 22, so that the carriage 10 is shown by a solid line a in FIG. It is maintained in a state parallel to the collective rail 22 so that it can move straight and stably without wobbling.

When the truck 10 reaches the rail branch portion 24,
The guide pins 13 to 15 are guided by the rail branching portion 24 while being divided into the separation rails 26 to 28, respectively, and the carriage 10 can change its traveling direction with almost no change in direction, and the direction changing portion 20. Will be moved to.

The direction of the carriage 10 at the direction changing portion 20 can be arbitrarily set by the distance 38 between the separating rails 26 to 28.

At this time, in the rail branch portion 24, the distance 37 between the transition points 34 to the separation rails 26 to 28 and the branch points 35 and 36 is smaller than the distance 16 between the guide pins 13 to 15 of the carriage 10. The guide pin 15 on the B side first enters the separation rail 28, then the center guide pin 14 enters the separation rail 27, and finally the guide pin 13 on the A side enters the separation rail 26. It will be.

Due to the time difference when each of the guide pins 13 to 15 moves to the separation rails 26 to 28, the carriage 10 is
From the state of solid line a, as shown by virtual line b temporarily,
The side B is swung.

By doing so, the guide pin 1
The trolley 10 at a stroke without causing a time lag in the transition from 3 to 15
It is possible to change the traveling direction of the trolley 10 more smoothly without overstraining as compared with the case of changing the traveling direction of the carriage 10.

When the carriage 10 is moved to the direction changing portion 20, the space 38 between the separating rails 26 to 28 becomes
Since it is slightly narrower than the space 16 between the guide pins 13 to 15 of the trolley 10, the trolley 10 cannot be in a state parallel to the collective rail 22 as in the solid line a,
Although it is smaller than the case of the virtual line B, it is slightly tilted like the virtual line C.

This is the part of the separation rails 26-28,
This is because when the trolley 10 is held in a state parallel to the collective rail 22 as in the case of the solid line (a), the trolley 10 may tilt in an arbitrary direction to cause wobbling during movement, and the directional change portion 20 By intentionally slightly tilting the dolly 10, the dolly 10 is held in the tilted position on the contrary, so that the traveling is stabilized.

The trolley 10 is provided with the separating rails 26 to 28.
When reaching the rail merging portion 25 from each guide pin 13 ~
15 is rejoined at the rail merging portion 25, the carriage 10 is changed in direction without changing its direction, and is transferred to the other straight traveling portion 19.

At this time, in the rail merging portion 25, a transition point 39 to each of the separation rails 26 to 28 and a space 42 between the merging points 40 and 41 are slightly narrower than a space 38 between the separation rails 26 to 28. Since it is made, the guide pin 15 on the B side
Will enter the rail merging portion 25 first, then the central guide pin 14 will enter the rail merging portion 25, and finally the A-side guide pin 13 will enter the rail merging portion 25.

Due to the time difference when the guide pins 13 to 15 move to the rail merging portion 25, the carriage 10 is
As indicated by a virtual line D, the shake on the A side gradually decreases from the state of the virtual line C.

By doing so, the guide pin 1
The trolley 10 at a stroke without causing a time lag in the transition from 3 to 15
It is possible to change the traveling direction of the trolley 10 more smoothly without overstraining as compared with the case of changing the traveling direction of the carriage 10.

The trolley 10 moved from the rail merging portion 25 to the collective rail 22 is in a state in which it is parallel to the collective rail 23 as shown by the phantom line E because all the guide pins 13 to 15 are simultaneously guided. Then, straight running part 19
To go and go.

As described above, according to the present invention, the three guide pins 13 to 15 and the corresponding separation rails 26 to 2 are provided.
With the simple configuration of 8, it is possible to change the traveling direction of the carriage 10 without changing the direction, and it is possible to save the turning space of the carriage 10.

FIG. 5 shows a second embodiment of the present invention, which is applied to a loading / unloading device 44 in a parking device 43 such as an automobile.

In this case, both the direction changing portions 20, 45 of the guide rail 21 formed in a loop shape.
May be constituted by the separating rails 26 to 28, but in the present embodiment, in particular, only one of the turning portions 20 is constituted by the separating rails 26 to 28, and the other turning portion 45 is constituted by the curved rail 46. I am trying to do it.

By doing so, the vehicle storage device 48 for storing the vehicle 49 in the vehicle storage space 47.
The trolley 10 carrying the vehicle 49 can be transported to the front of the vehicle, and the direction of the vehicle 49 to be put in and the vehicle 49 'to be put out can be changed by 180 degrees without using a turntable or the like. .

Except for the above, the structure is the same as that of the above-mentioned embodiment, and the same operation and effect can be obtained.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and the direction change angle of the carriage is not limited to 90 degrees, and other various modifications are possible within the scope not departing from the gist of the present invention. Of course, it can be added.
