Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention enables smooth running of a hanging wheel for a movable wall (hereinafter referred to as a hanging wheel) at an orthogonal section (intersection) of a hanger rail, which is a running track. The present invention relates to a travel control device.

(Prior art) Fig. 11 (b) shows an example of a running state of a conventional hanging wheel (a state in which the hanging wheel approaches a part perpendicular to the hanger rail)
shows.

In the figure, 1 is the suspension wheel body, which has a vertical suspension bolt 2 (shaft with a bolt for suspending the movable wall below) below the center, and two vertical wheels on each of the 4111 sides of the front, rear, left and right sides. 3a, 3a, 3b, 3b, 3c.

3c, 3a, and 3a are rotatably provided. Reference numeral 4 denotes a hanger rail installed on the ceiling, which intersects perpendicularly at the intersection shown in the figure.

However, these hanger rails are
Figure 4 shows a state where the central part is cut on a horizontal plane, and the running plate 4 at the bottom is shown. However, as shown in FIG. Cross section approximately C consisting of the upper wall 4c and the guide rail 4a provided continuously in the longitudinal direction at the center of the lower surface of the upper wall 4c
The vertical wheels 3a, 31. ．． 3c,
3a comes into contact with the upper surface (running surface) of the running surface 4a.
As a result, the hanging wheel main body 1 runs on the hanger rail with the movable wall suspended.

Reference numeral 5 denotes a groove continuous in the axial direction of the rail and having an arcuate cross section formed on the upper surface of the running plate 4 □.
This is to prevent contact and interference between the upper surface of the suspended wheel body 1 and the upper surface thereof when the suspended wheel body 1 is traveling.

On the upper surface of the suspension wheel body 1, 4+115 guide rollers 61
．． 6&, 6c, and 6a are arranged at regular intervals, and as shown in the figure, they contact the left and right sides of the guide rail 4- through a minute gap, and the hanging wheel main body 1 is connected to the guide rail 4a.
The vehicle will be guided by the driver and will maintain a straight line.

Then, when the hanging wheel main body 1 moves straight in the direction of arrow X, for example, and comes to the intersection of the hanger rails shown in FIG.

The front wheel 3.1 of the three wheels passes over the cut E (groove for the hanging shaft 2 to pass through) in the hanger rail 4, and the hanging wheel moves further forward to the position shown in Fig. 11(a). As shown in the figure, when the hanger rails reach the center of the intersection, the vertical wheels 3c, 3-, which had been in rolling contact with the upper surface of the running plate 4a, fit into the grooves 5 perpendicular to the running direction, and as a result, all The vertical wheels 38 to 3d are arranged in the arc-shaped groove 5 in the longitudinal and lateral directions.
This causes the suspension wheel to temporarily stop moving.

Next, when a force is applied to the hanging wheel main body 1 in any direction from front to back, left to right, and at this central position, the hanging wheel main body 1 starts to move in that direction.
It is possible to change the running direction to any direction.

(Problems with the prior art) However, as mentioned above, such a hanging wheel can freely change the running direction and has extremely high practicality.
The suspension force is strong because the load is received by a large number of vertical wheels, but as mentioned above, all the vertical wheels of the hanging wheel fit into the groove 5 at the center of the orthogonal part of the hanger rail, resulting in this stuck state (the suspended wheel When attempting to start a new suspended vehicle from a state in which the entire suspended vehicle has sunk by the depth of the groove 5, the vertical wheels in the traveling direction escape from the groove 5 and the running plate 4
．． The depth of this groove 5, which must ride on the upper surface (travel surface), is such that when the hanging vehicle is running straight, the vertical wheels (31, 3+,) perpendicular to the traveling direction of the suspended vehicle can run on the traveling plate 4.
．． It is necessary to make the 8 sides deep to a certain extent so as not to interfere with the top surface, and since the vertical load acting on each hanging wheel is usually several hundred to several tons, it is necessary for the vertical wheel once stopped to climb over the groove 5. This creates a huge amount of resistance in order to escape.

In addition, in the case of a movable wall, in order to move it, it is not possible to directly push the hanging wheel stored in the ceiling, but by pushing the movable wall hanging from the hanging wheel, so the above-mentioned method is used. If the resistance due to the groove 5 is large, it may become practically impossible to move the hanging wheel from the orthogonal part of the hanger rail. Also, if you try to move it forcibly, you will damage the hanging bolts and the hanging wheel.

[Purpose of the invention]

Therefore, it is an object of the present invention to enable a hanging wheel that has once stopped at the center of an intersection of hanger rails to be started with a small force.

[Structure of the invention]

The main means adopted by the present invention in order to achieve the above object is that the lower part has running wheels exclusively for straight running that roll on the running rails, and the upper part has intersections of the above-mentioned running rails. In an intersection traveling control device for a movable wall suspension vehicle equipped with ball-type auxiliary wheels that roll on auxiliary rails provided only in This is an intersection traveling control device for a movable wall hanging wheel, in which the distance between the rail contact surface of the rail contact surface and the rail contact surface of the auxiliary wheel is equal to l, or L>1.

[Effect]

When the movable wall hanging wheel travels on the traveling rails and reaches an intersection of the traveling rails, the auxiliary wheels run onto the auxiliary rails provided only at the intersection due to the inertia of the hanging wheel.

Here, since the distance between the rail contact surface of the travel wheel and the rail contact surface of the auxiliary wheel is shorter than the distance between the top surface of the travel rail and the top surface of the auxiliary rail, when the auxiliary wheel rides on the auxiliary rail, , the traveling wheels are in a state of being lifted off the traveling rails, and the movable wall is supported only by the auxiliary rails and the auxiliary wheels that roll into contact with the auxiliary rails.

In this state, the movable wall hanging wheel stops at the center of the intersection of the traveling rails. The auxiliary wheels are in the form of balls and do not stop when they fit into a groove or the like, and can roll in any direction, so they move in any direction pushed by the operator.

As this progresses, the auxiliary wheels will eventually come off the auxiliary rails, and the traveling wheels will be transferred onto the traveling rails, so that the entire load of the moving wall will be supported by the traveling wheels, and the moving wall will be transported along the traveling rails. .

In the following embodiments, the same reference numerals are used for the same elements as those of the conventional device shown in FIG. 11.

The following example is only one specific example of the present invention, and is not intended to limit the technical scope of the present invention.

First, using Figures 1 to 5, as a running rail,
The case where H-shaped steel is used will be explained.

In FIG. 1, reference numeral 10 denotes a running rail made of H-shaped steel, and is provided with a running plate 12& having a running surface 12 on which the running wheels 11 of the suspended vehicle roll. End surface 13 of running plate 121
, 13 constitute a guide surface on which the guide collar 14 slides.

On the other hand, the movable wall hanging wheel 15 running along the traveling rail 1O has hanging bolts 16 for hanging the movable wall.
The suspension wheel main body 18 has a horizontal square plate shape and is rotatable via a thrust bearing 17.

At the four corners of this hanging wheel main body 18, vertical hanging wheel main body shafts 19, 19. ... is fixed. A guide roller 20 using a radial bearing as is is fitted onto the upper end of each suspended wheel main body shaft 19.

A wheel fixing plate 22 is fixed below the guide roller 20 to which a ball-type auxiliary wheel 21 using a thrust bearing is attached.

Further, below the wheel fixing plate 22, a wheel fixing block 23 for attaching the traveling wheels 11 is fixed. The running wheels 11 roll on the running surface 12 of the running rail 10 as described above, and the running rail 10 is connected in a cross shape at the intersection 42 as shown in FIG. In order to enable the movable wall hanging wheel 15 approaching the intersection 42 to transfer to any of the above-mentioned traveling rails 10 that are orthogonal to each other, two wheels are placed on the sides of each wheel mounting block 23 so that the running direction thereof is perpendicular to the other. They are installed one by one.

Note that 24 is a retainer for preventing the balls of the auxiliary wheel 21 from falling.

Next, the structure of the intersection portion 42 of the traveling rail 10 will be described with reference to FIGS. 2 to 4.

In the figure, 25 indicates the traveling rail 10.10. ... as the fourth
As shown in the figure, it is a connecting plate for connecting in a cross shape, has a regular octagonal shape in plan view, and is attached to the end of the running rail 10 with bolts 26. As shown in FIG. 3, a guide plate 28 having a square-shaped guide groove 27 is fixed to the lower surface of the connecting plate 25. As shown in FIG.

A main shaft 31 having a spherical surface 29 and a male threaded portion 30 at its lower end passes through a hole that vertically passes through the center of the connecting plate 25 and the guide plate 28 . A boss portion 33 of the traveling rail 32 is screwed.

Further, a substantially square plate-shaped auxiliary rail 35, which forms a running surface 35a of the auxiliary wheel 21, is integrally attached to the lower end of a boss portion 34 formed at the center of the guide plate 28.

The running surface 35□ of the auxiliary rail 35 and the running plate 12, l
The distance between the running surface 12 (Fig. 2) of the running wheel 11 and the rail contacting surface of the auxiliary wheel 21 (Fig. 2) is set slightly longer than the distance Mff (Fig. 1) between the rail contacting surface of the running wheel 11 and the rail contacting surface of the auxiliary wheel 21. . The difference between the distances ML and 6 is, for example, about 0 to 21 m, preferably about 0 to Q, 5 * m, so that the auxiliary wheels 21 can easily ride on the auxiliary rail 35, and the distance between the auxiliary rail 35 and the running rail is It is desirable that there is almost no impact when transferring to the 10.

A ball holding tube 37 is screwed into a vertical hole 36 formed in the center of the boss portion 33 of the central running rail 32, and a positioning ball 38 accommodated in this ball holding tube 37 is attached to the bottom end of the main shaft 31. A coil spring 39 that is fastened between the spherical surface 29 and the spherical surface 29 always elastically presses it downward.

A positioning hole 40 having a crescent-shaped cross section is formed in the center of the upper surface of the hanging wheel main body 18, into which the lower part of the positioning ball 38 can enter.

The running surface 12 of each running plate 12& and the upper surface of the central running rail 32 are formed on the same surface, and there is a space between the end of the running plate 121 and the central running rail 32 on the suspension wheel main body shaft 19. A cutout groove 41 through which the attached guide collar 14 can pass is formed in the shape of a valve.

Next, the operation of the above embodiment will be explained.

When the movable wall hanger 15 is running along the running rail 10, the running wheels 11 are in rolling contact with the running surface 12 of the type 1 running rail 10, as shown in FIG. The collar 14 is the running plate 12. By contacting the end surface 13 of the movable wall hanging wheel 15, the movable wall hanging wheel 15 moves straight. At this time, the load of the moving wall applied to the hanging bolt 16 is entirely transferred to the four traveling wheels 11.11 facing in the traveling direction of the hanging vehicle.
It is supported by...

Next, as shown in FIG.
Traveling rail 10.10.・
The operation when approaching the intersection 42 will be explained. However, FIG. 5 shows a state in which the movable wall hanging wheel 15 has come to the center of the intersection 42.

In this case, the traveling wheels 11 on the front side in the traveling direction. When the auxiliary wheel 21 is about to reach the notch groove 41, the auxiliary wheel 21 rides on the running surface 35II of the auxiliary rail 35. In this case, the distance ML between the running surface 12 and the running surface 358, and the distance l between each rail contact surface of the running wheel 11 and the auxiliary wheel 21
Since the difference between the two wheels is small and the inertia of the movable wall hanging wheel 15 is acting, the auxiliary wheels 21 easily ride on the running surface 35□ of the auxiliary rail 35. There is no inconvenience that the wheel 11 comes off the wheel at the notch t141, and the load of the moving wall applied to the hanging wheel 16 is gradually transferred to the auxiliary rail 35 via the auxiliary wheel 21.

Furthermore, as the movable wall hanging wheel 15 moves forward in the direction of the arrow X, the rear running wheels 111. crosses the notched groove 41, and at this time, the traveling wheels 111. The auxiliary wheels 21 provided on the upper part of the auxiliary rail 35

All the auxiliary wheels 21 installed in ... are transferred onto the auxiliary rails 35 as shown in FIG. Become.

As the auxiliary wheel 21 moves onto the auxiliary rail 35 as described above, the guide roller 20 provided at the upper end of the suspension wheel main body shaft 19 is fitted into the guide groove 27 formed in the guide plate 28. Even when the guide collar 14 separates from the end surface 13 of the traveling plate 128 at the notched groove 41, the guide roller 20 is guided by the guide groove 27, so that the movable wall suspension wheel 15 maintains its straightness.

When the movable wall hanging wheel 15 reaches the center of the intersection 42, the positioning ball 38, which is always elastically pressed downward by the coil spring 39, moves onto the hanging wheel main body 1.
The movable wall hanging wheel 15 is inserted into the positioning hole 40 formed at the center of the cross section 8, and the operator can know by manual registration at this time that the movable wall hanging wheel 15 has come to the center of the intersection 42. Without the sense of position provided by the positioning balls 38 as described above, when the operator moves the movable wall hanging wheel 15 that has stopped at an uneven position in the direction of another traveling rail 15, the operator may move it in a direction where there is no guide groove 27. By pushing the wall hanging wheel 15, the problem that the guide roller 20 hits the wall of the guide plate 28 and the movable wall hanging wheel 15 and the hanging bolt 16 are damaged can be avoided.

When the movable wall hanging wheel 15 is stopped at the center of the intersection 42 as shown in FIG.
are all in a state of being lifted from the running surface 12 of the running rail 100, so there is no interference with the running surface 12, and the load of the moving wall is completely supported by the auxiliary wheels 21.

The auxiliary wheel 21 is of a so-called ball type using a thrust bearing itself, and the load of the moving wall is supported by a plurality of balls, so the load per ball is small and there is no problem of premature wear.

In this state, when the movable wall hanging wheel 15 is stopped at the center of the intersection 42, the movable wall hanging wheel 15 is further moved in the direction of the arrow X or in the opposite direction, or in the direction perpendicular to the arrow
For example, when moving further in the direction shown by arrow X, the front auxiliary wheels 21 will come off the auxiliary rail 35, Wheels 11. ．． 11. transfers to the running surface 12 of the traveling rail 10, so no large impact is applied to the moving wall and the moving wall hanging wheel 15 when restarting the moving wall hanging wheel 15 from the center of the intersection 42 as described above. The auxiliary wheels 21 of the movable wall hanging wheel 15 do not fall into a groove or the like, but only roll on the planar running surface 351, so that restarting can be performed very easily.

As mentioned above, the front running wheels 11. is the front running surface 1
2, the rear auxiliary wheels 21 then move onto the running surface 35.2 of the auxiliary rail 35. It runs on the top and eventually falls off the end surface, but at that time the rear running upper wheel 11b transfers to the running surface 12 of the front running rail 10,
Eventually, four running wheels 11, 11. ... all start rolling on the running surface 12 of the running rail 10, and these four running wheels 11, 11 . ... will support the load of the moving wall.

Next, the second embodiment shown in FIGS. 6 to 9 will be explained. In this embodiment, a traveling rail is formed by the hanger rail 4 similar to that shown in FIG.
3 has a cutout groove 45 through which the hanging bolt 44 can pass.
(corresponding to the groove 5 in FIG. 11) and a groove 46 (corresponding to the groove 5 in FIG. 11) for preventing interference between the running wheels and the running plate 43 are formed.

As shown in FIGS. 6 and 7, the movable wall hanging wheel 47 that can run along the hanger rail 4 as described above has an upper body 48 in the shape of a square plate and a lower body 49 in the shape of a square block. , the main component is a hanging wheel body 51 constituted by an intermediate body portion 50 that connects the upper body 48 and the lower body 49.

A vertical auxiliary wheel mounting shaft 52 is screwed onto each of the four corners of the upper body 48, and a ball-type auxiliary wheel 53 constructed using the thrust bearing itself is thereby attached to the four corners of the upper body 48. A guide roller 54.54° (guide roller 6 &
-corresponding to 6a) are each rotatably attached.

Further, the lower main body 49 has four parts as shown in FIG.
A recessed portion 55 is formed on each side surface, and the recessed portions 55, 55 . . . . each center running wheel 5

Furthermore, the central running wheel 56 is provided on the side surface of the lower body 49.
Main running wheels 57 (
A total of 81 wheels) are attached, the main running wheels 57 protrude outward from the center running wheels 56, and all running wheels 5

Note that the intermediate body portion 50 has a structure as shown in FIGS.
9 is screwed onto the lower fuselage 49, and a hanging bolt 44 is rotatably mounted between the lower fuselage 49 via a thrust bearing 60.

The upper surface 50 of this intermediate body portion 50. , there is a positioning hole 62 having a semicircular cross-section and the same radius as the positioning ball 61, which can receive the lower spherical surface of the positioning ball 61, which will be described later.
is formed on the vertical axis.

Next, the structure of the hanger rail intersection through which the movable wall hanging wheel 47 can pass will be described with reference to FIGS. 8 and 10.

In FIGS. 8 and 10, reference numeral 63 denotes a hexagonal connecting plate in plan view for joining the cross-shaped hanger rails 4.4 to the intersections 64, 64. As shown in the upper left of FIG.
3 rolls on the auxiliary rail 67 and the hanger rail 4
A central running rail 68 arranged on an extension of the running plate 43 of
and four corner pillars 69 and 70 that connect the guide plate 66, the auxiliary rail 67, and the central running rail 68 as main components.

The distance L (see FIG. 8) between the upper surface of the auxiliary rail 67 constituting the intersection 64 and the upper surface of the traveling rail, that is, the traveling plate 4 & of the hanger rail 4, is the same as the rail contact surface of the main traveling wheel 57. , the distance between the auxiliary wheel 53 and the rail contact surface! ff
(Fig. 6), or - or slightly longer than l.

The above distance 41. The difference in L is set to, for example, 0 to 2 ml, preferably θ to 0.5 fl.

As mentioned above, the center running rail 68 and the auxiliary rail 67 are all attached to the four corners of the intersection 64 by the pillar parts 69, 70, and the hanging bolts 44 pass between the adjacent center running rails 6B. A notched groove 45 is formed in a cross shape.

Furthermore, a cutout groove 71 is formed between the adjacent auxiliary rails 67, 67, through which the intermediate body portion 50 of the suspension wheel body 51 passes. In addition, grooves 5 are formed in the upper surface of the central running plate 68 in a cross shape as shown in the figure.

A cylindrical ball holding cylinder 72 is provided on the lower surface of the guide @66.
．． 72 is fixed with a bolt 73, and the positioning ball 61 is housed in a hollow portion of this ball holding cylinder 72 so as to be vertically movable. The positioning ball 61 is always elastically biased downward by a coil spring 74 built into the ball holding cylinder 72.

Next, the operation of the embodiment shown in FIGS. 6 to 10 will be explained.

In FIG. 10, a state in which the movable wall hanging wheel 47 has advanced in the direction of the white arrow Y and has approached the intersection 64 is shown by a two-dot chain line. In this case, the front main running wheel in the direction of travel is 571, the rear main running wheel is 575, and the left and right wheels are 57c and 57. Let it be i. Further, the center running wheels corresponding to these main running wheels 571 to 57a are designated as 56. ~56
Let it be J.

Furthermore, the auxiliary wheel on the left side of the front in the direction of travel is 53□, and the auxiliary wheel on the right side in the direction of travel is 531. , an auxiliary wheel 53° on the rear left side in the direction of travel, and an auxiliary wheel 53a on the rear right side.

First, when the movable wall hanging wheel 47 is inside the hanger rail 4, the left and right main running wheels 57c, 57J and the left and right center running wheels 56e, 56a are all in rolling contact with the running plate 4a of the hanger rail 4. The load of the moving wall is supported by the wheels.

Eventually, when the movable wall hanging wheel 47 approaches the intersection 64,
As shown in the figure, the auxiliary wheels 53 and 53&
runs onto the auxiliary rail 67.

The upper surface of the auxiliary rail 67 constituting the intersection 64 and the running rail, that is, the running plate 4 of the hanger rail 4. The structure is such that the distance 1 (Fig. 6) between the rail contact surface of the main running wheel 57 and the rail contact surface of the auxiliary wheel 53 is shorter than the distance L (see Fig. 8) between the upper surface and the top surface. However, since the difference in the above-mentioned distance and l is about 0 to 2, preferably about 0 to 0.5, the auxiliary wheel 53 easily transfers onto the auxiliary rail 67 due to the inertia of the hanging wheel.

As the movable wall hanging wheel 47 travels, the rear auxiliary wheels 53C%53. The movable wall also rides on the auxiliary rail 57, and eventually the entire load of the moving wall applied to the hanging bolt 44 is supported by the auxiliary wheels 53. At this time, the guide roller 54 is fitted into the guide groove 65 and guided.
The moving direction of the movable wall hanging wheel 47 is always kept straight.

As the movable wall hanging wheel 47 moves further in this manner, the auxiliary wheels 538 and 531 on the front side in the direction of movement. will derail into the notch groove 71, but at this point the left and right main running wheels 5
7c, 57- or left and right central running wheels 56c, 56
．． 1 comes into rolling contact with the running surface 688 of the center running rail 68, and the load of the moving wall applied to the hanging bolt 44 is supported by these center running wheels 56e, 56J or the main running wheels 57c157a. Therefore, there is no inconvenience such as a large impact being applied to the movable wall hanging wheel 47.

As the movable wall hanging wheel 47 moves further in this state, the front auxiliary wheels 531 and 53 eventually cross the notched groove 71 and ride on the front auxiliary rail 67, and as a result, the hanging bolts 44 are hooked again. The load is 4111 auxiliary wheels 53. ~53a.

When the movable wall hanging wheel 47 reaches the center of the intersection 64, the positioning ball 61 attached to the guide plate 66 enters the positioning hole 62 bored into the upper surface of the upper body 48 of the movable wall hanging wheel 47. Mobile wall hanging wheel 47
When the operator notices that the movable wall hanging wheel 47 has come to the center of the intersection 64, the operator stops the moving wall hanging wheel 47 at that position.

Thereby, the movable wall hanging wheel 47 can change direction in the direction indicated by arrow Y or the opposite direction, and furthermore, can change direction from there to either the left or right direction.

The movable wall hanging wheel 47 thus stopped at the center of the intersection 64.
When further pushed in the direction of the chair in the four directions described above, the movable wall hanging wheel 47 starts moving again due to the force, and the auxiliary wheels 53c and 53a on the rear side in the direction of movement move into the notched groove 71 as described above.
When crossing the road, the main running wheels 57c, 57a or the center running wheels 56c, 56J come into contact with the center running rail 68, so that almost no impact is applied to the movable wall hanging wheel 47, and soon all the auxiliary wheels 53 After riding on the auxiliary rail 67 again, it advances further into the hanger rail 4, and the center running wheels 56 on the left and right in the direction of travel and the main running wheels eventually reach the running plate 4. of the hanger rail. It will be transferred to.

〔Effect of the invention〕

As described above, the present invention has a ball-type running wheel on the lower part that is exclusively for straight running and rolls on the running rail, and has a ball type on the upper part that rolls on the auxiliary rail provided only at the intersection of the above-mentioned running rail. In the intersection travel control device for a movable wall hanging vehicle equipped with auxiliary wheels, the distance between the top surface of the travel rail and the top surface of the auxiliary rail is the same as the distance between the rail contact surface of the travel wheel and the rail contact surface of the auxiliary wheel. Since this is an intersection travel control device for a movable wall hanging vehicle, the distance is equal to M1 or L>1, the running wheels of the movable wall hanging vehicle are controlled at the center of the intersection like a conventional hanging vehicle. The auxiliary wheels do not get stuck in the groove and stop, but the auxiliary wheels are placed on the flat auxiliary rails so that they can easily roll in any direction, making it possible to restart a stopped moving wall hanging wheel. It requires almost no force to move, and therefore there is no risk of damage to the moving wall hanger, hanging bolts, or other moving wall itself.
This provides a movable wall that is highly durable and easy to operate.
