JPS607116B2 - Bending travel control device for mobile wall hanging wheels - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device for accurately bending and traveling a hanging wheel for a movable wall. The diameter of the main wheel is made different to prevent it from moving in the same direction, and this difference in main diameter is used to control the running direction of the hanging wheel by interference with the main wheel guide rail installed on the hanger rail side. At the same time, the diameter of the hanger rail was reduced.

A movable wall for partitioning a room into any shape can be moved by attaching hanging tools such as hanging bolts from a hanging wheel that runs on a hanger rail installed in the ceiling, and attaching a movable wall to the end of the hanging wheel.
However, as movable walls have recently become heavier and more versatile, there has been a demand for improved running performance and complex running trajectories.

Therefore, the radius of curvature of the hanger rail is required to be small when the hanging wheel bends, which poses a difficult problem when the hanging wheel bends. For example, as shown in FIGS. 1 and 2, an example of a hanging wheel recently developed by the present inventor has a pair of rotating main wheels 2, 2 rotatably provided on the left and right sides of a hanging wheel main body 1, and A pair of rotating sub-wheels are rotatably attached to the front and rear of the main mechanism 2, respectively, and the moving wall is suspended by many wheels, so that the heavy moving wall can be transported.

In the example shown in the figure, two rotating wheels 3a, 3b and 3c, 3d are provided before and after the main wheels 2, 2, and one of them is
Each of the rut wheels 3a is provided with a disc-shaped guide collar that is shaped like the subwheel 8a.

A ryu ring with a guide tsuba-umara integrated in this way is especially called a guide ring. In addition, one or more horizontally provided guide horses are attached to the lower part of the main body of the hanging wheel.
, 2, a hanging bolt 6 is mounted vertically on the bag core 6, which is rotatably provided on the rare car body W, and is arranged so that a movable wall is suspended from the lower end of the hanging bolt 6. ``The main wheels 2 and Netsumarihoko ~ 3G are transferred to the bottom wall & seed of the Hasoga ~ rail crab laid on the ceiling to transport the lowered movable wall of the belt bolt needle. Since the guide horse is inserted in the guide groove between the wall false boxes ~ as long as the guide groove 9 continues continuously, the hanging wheel will be in this guide groove g
The guide groove can be guided straight or curved, but as shown in Fig. Since the guide Shizuha can move in either the direction of the guide groove ga (direction of arrow is lost.

Therefore, with this hanging wheel, we used a roughly triangular guide with the hypotenuse side forming an arc as shown in the figure...The electric turtle was attached to the lower surface of the upper wall of the hanger rail, and the guide tsuba rope of the leading guide wheel 3a was connected to the guide ring. Even if the guiding wheel interferes with the hypotenuse turtle 0 of the Yamaru 1 army, the guiding wheel changes direction along the hypotenuse, and the entire hanging wheel is dragged by the guiding wheel and runs in a bending direction in the direction of arrow D. If you want the car to go straight, use a suspended wheel with a guide wheel in the position shown in the figure to guide the car between the straight section Tomi g of the Tomiden and the Tomizuru on the bottom side of the hanger rail. Due to the passage of the tsuba, the guide tsuba and the guide rail do not interfere with each other and the handle wheel runs straight.

Since the suspension wheel is suspended by a total of six wheels, it is possible to support a very large weight.Moreover, there is a large rope in front of the center part of the suspension wheel (the position where the suspension device is installed). Because it is equipped with the guide wheel that forces the suspended vehicle to turn at a desired position, the rotational force during bending is large.This suspended vehicle suspends a heavy moving wall and can be turned very easily. It is.

However, with such a hanging wheel, as the hanging wheel moves further in the direction of the arrow m from the position Kametomi a shown by the solid line in Figure 3, the direction of the subsequent guide loaf ant a' is regulated. Therefore, the hanging wheel will move straight in the direction of the arrow W. Therefore, the hanging wheel will eventually advance to the position turtle 6b indicated by the two-dot chain line, and the hanging wheel will move to the tongue 6 on the bottom of the hanger rail. The suspension bolt 6 collides with the movable wall, and not only applies a large impact to the moving wall, but also causes the tongue to wear out. The collision with Troop No. 6 still gives a shock to the moving wall, which further impedes the movement of the guide roller vine a, and hinders the smooth running of the moving wall.

A tongue with this shape is absolutely necessary when the hanging wheel crosses the branch of the hanger rail as shown in the figure, or to prevent the rutted wheel from slipping into the guide groove. ``For the reasons mentioned above, this is causing a problem with the stable running of this suspended wheel.

The purpose of the present invention is to eliminate the drawbacks of the conventional movable wall hanging wheels as described above. In addition to providing a pair of rotation rate wheels with different speeds, a main guide rail that interferes with the large rotating main wheel is provided at the branching part of the hanger rail. ``A pair of rotating driving wheels are attached to the sides of the hanging wheel body at the front and rear of the rotating main wheel, and a guide collar is provided that rotates one of the rotating driving wheels as a body with the rotating ring. In addition, the above-mentioned rotating main wheel is installed in a position where its outer surface protrudes outward from the outer surface of the rotating wheel, and the hanger rail is installed at a position angled back and forth from the back of the movable wall suspension at the bottom of the hanging wheel. To provide a bending travel control device for a movable wall hanging wheel, which is characterized by a configuration in which one guide rod is inserted into each guide groove of the hanging wheel and guides the hanging wheel main body along the hanger rail.

In addition, a crane trolley described in Japanese Patent Application Laid-open No. 5 Senichi No. 112055 is known as an example in which wheels are arranged in three rows and flange is provided on the front and rear wheels. It is clear that the guard is used to prevent a bogie that runs only on straight rails from coming off the straight rail, and is not intended for use in curved running.In other words, as shown in FIG. 9, the bogie 50' These three pairs of wheels 51a?51b, 5
2a, 52b, 53a, 53b as three parallel bags 54,
55, 56, front and rear wheels 51a and 53
Attach the collars 58a and 59a to the rail 57a.
The rail 57 (57a
and 57b).

In this case, in order to smoothly interfere with the flange 58a and the edge green 60a, the shaft 54 supporting the wheel 51a to which the flange 58a is attached must be placed at the contact portion 61a between the flange 58a and the edge green 60a as shown in the drawing. In other words, when the direction of the tangent to the arcuate edge 60 at the contact portion 61a matches the traveling direction of the wheel 51a (the direction of the arrow X), the smoothest surface is obtained. Interference is obtained, and the truck 60 also changes direction smoothly. On the other hand, the direction of the tangent of the edge 60b at the contact portion 61a and the traveling direction of the wheel 51a (the axis 5
If the angle is significantly different from the perpendicular direction ( Since it does not slip easily, it is impossible to travel around bends.

In this regard, in the case where the front and rear wheels of the wheels arranged in three rows as shown in FIG. If you try to make a smooth bending run by facing the tangent to the edge 60a of the rail 57a with which it comes into contact, the rear wheels 5
3a comes off the edge 6Qa, making it impossible to run.

In this case, if the edges are interfered so that they come to the position 60b shown by the two-dot chain line, both the front and rear wheels 51b and 53a will come on the rail 57a, and the direction of each collar 58a and 69a (the direction of travel) Since the direction (same) is significantly different from the direction of the tangent to the edge 60b, the collar 58a or 59b digs into the edge green 60b, making it impossible to run.

To prevent such inconvenience, it is necessary to make the radius of curvature of the rail 57 very large, and it is necessary to make the radius of curvature of the rail 57 very large. In the case of rails, the space in which they can be installed is limited, so it is impossible to increase the radius of curvature.

Therefore, in a truck that has flanges on both the front and rear wheels, such as the one described in JP-A-51-112055,
It is understood that it is not possible to travel with a small radius of curvature and is intended only for curving travel with an extremely large radius of curvature or straight travel.

On the other hand, a wheel 51 with a flange is provided at the front of the truck.
If it is attached only to either wheel 53a or wheel 53a provided at the rear, the above problem will not occur,
It is understood that by aligning the direction of the tsuba with the direction of the tangent to the end green, smooth bending can be achieved.

The present invention employs a guide wheel in which a flange is integrally provided only on either the front or rear wheel (Liu Lun), and smooth bending running is expected.

In addition, the bogie described in the above-mentioned Tokukan Sho 51-112055 publication has a central wheel and wheels in front and behind it arranged in a straight line in the front and back direction as shown in Figure 9, and such a suspended bogie can be used for bending motion. In this case, the radius of curvature of the traveling locus of the leading wheel 51a is large, which forces the width of the hanger rail that accommodates the hanging wheel to be increased, resulting in a large hanger rail.

Since hanger rails are installed vertically and horizontally along the ceiling, increasing their size is extremely uneconomical. In this regard, since the present invention has the front and rear sub wheels arranged inside the central main wheel as described above, the radius of curvature is 4.
・It significantly contributes to the A-shaped hanger rail. Next, embodiments embodying the present invention will be described in detail with reference to the accompanying drawings.

FIG. 4a shows 6 used in a control device which is an embodiment of the present invention.

FIG. 3 is a plan view including a hanger rail showing a running state of the vehicle. In Figure 4, the hanging wheel 2
The hanging wheel main body 21 forming the main body of 0 has an insertion hole 22 in the vertical direction.
The head 24 of the hanging bolt 23, which is an example of a hanging shell for hanging a movable wall, is inserted into the insertion hole 22 with iron, and the head 24 is installed in the step 25 provided at the upper part of the insertion hole 22. has been,
A diamond 26 screwed onto the top of the stepped portion 25 prevents it from slipping out.

The hanging wheel main body 21 has protruding parts 27, 27 on the side walls of the central part that protrude in the left-right direction, respectively. Freely rotating main wheels 29 and 30 are mounted, and the center line h of the main wheels 29 and 30 passes through the center 31 of the suspension bolt 23.

Secondary wheels 33a, 3 are attached to the rear side surfaces 32, 32 of the hanging wheel main body 21.
3b, and the front side surfaces 34, 34 have secondary wheels 33c, 33d.
are each mounted rotatably.

On the inner side of one of the secondary wheels 33c and 33d, a disc-shaped guide collar 35 having an outer diameter larger than the outer flange d of the secondary wheel 33c is integrally formed with the secondary wheel 33m. The subwheel with guiding maxims is hereinafter referred to as the introduction theory.

The side surface 36 of the secondary wheel including the guide wheel 33c is provided inward from the side surface 37 of the main wheels 29, 30 by a distance i, as shown in FIG.

In this way, since the side surfaces 36 of the main wheels 29 and 30 are made to protrude outward from the side surfaces of the front and rear wheels, the radius of the travel locus of the secondary wheels during bending travel becomes smaller as described above, allowing a small hanger rail to be used. It becomes usable. The shafts 38 and 39 protruding from the lower part of the hanging wheel main body 2 are each inserted into a guide groove 9 between the bottom walls 8 and 8 of the hanger rail 7 to both guide the hanging wheel and prevent the hanging wheel from swinging sideways. Horizontal guide wheels 40 and 41 are rotatably provided.

The hanging wheel 20 as described above is housed in a hanger rail 7 having a C-shaped cross section as shown in FIG. By contacting the walls 8, 8, the hanging bolt 2
In addition to transferring while supporting the load of the moving wall that was applied to 3.
The movable wall is conveyed in the direction of the guide groove by guide rollers 40 and 41 which are played in the guide groove 9.

Also, when the hanging wheel bends and travels at the branching part of the hanger rail, the guide rail 11 attached to the top coat 12 of the hanger rail 7 and the guide maxim 35 of the theory 33c interfere with each other, controlling the traveling direction of the hanging wheel, and Also the upper wall of hanger rail 7! Main argument guide rail 42 provided in 2
and the main axis 29 on the large diameter side interfere to control the bending movement of the hanging wheel.

The running state of the above-mentioned hanging wheel on the branched hanger rail will be explained next.

In Figures 8a-c the branches of the hanger rail are shown. That is, the branching parts are the right side bottom wall 8a of the straight rail, the left side bottom wall 8b of the bent rail, and the left side bottom wall 8 of the straight rail.
c and a blue section 16 that is integrated with the right bottom wall section 8d of the bent rail, and as shown in FIG. In this case, when the hanging wheel 20a shown by the solid line moves in the direction of the arrow V, it does not interfere with the small king theory 301 or the main theory guide rail 42, and the guide collar 35 of the guide wheel 33c moves along the straight side of the guide rail 11. 13 and the side surface 14 of the bottom wall 8a on the straight line of the hanger rail, and moves straight to the position shown by the two-dot chain line 20b, thereby running in a straight line.

On the other hand, as shown in FIG.
Because it interferes with the bent side surface 10 of 1, the hanging wheel 20c moves in the direction of the arrow, and the left main wheel 29 interferes with the main guide rail 42 and is guided along it. , the hanging wheel moves to the position 20d shown by the two-dot chain line, the rotation or swinging of the hanging wheel 20d in the direction of the arrow skin is suppressed, and the collision between the tongue part 16 and the hanging bolt 6 as shown in FIG. 3 occurs. Also, inconveniences such as the guide roller 40 going into the guide groove 9c are avoided. The suspension wheel shown in FIG. 8c is of a type without a guide, and can be used when the load on the moving wall is light.
Due to interference with the main wheel guide rail 42, the suspension wheel moves from the position 20c shown by the solid line to the position 20f shown by the two-dot chain line.
Move to. Next, we will discuss the four-wheeled hanging wheel in Figure 5 a~
This will be explained with reference to c.

In this case, the suspension wheel body 21, suspension bolt 23, guide roller 4
0 and 41 are the same as those shown in the fourth diagram, and main lines 29 and 30 also have different outer diameters. And the secondary wheels are one 33e on the front right side and one 33e on the rear left side.
f is provided, and one of the eight grave wheels 33e is a secondary wheel provided with a guide collar 35a. Further, in the hanging wheel shown in FIG. 6a, two guide wheels 33g and 33h are provided. However, one guide wheel 33M has a diameter of 4 mm, and its guide collar 35b is also small, so it does not interfere with the guide rail, but does interfere with the side surface 14 of the bottom wall 8 of the hanger rail 7, as shown in Figure b'. If the guide roller 41 breaks down due to wet weather, the guide rollers 35c and 35 of different sizes can be used.
The movement along the guide groove is controlled by b.Another modification of the hanging strap is shown in FIG.

Figure a shows a case where one guide wheel 33i is installed in front or behind the large main wheels 29 and 30, and b shows a case where one subwheel 33i and 33j are installed each on the same front and rear sides. (One side may be used as a leading theory), c has two regular wheels 33m and 33n at the front or rear, one of which is a guiding wheel, and one subwheel 3 at the rear or front.
3p is provided, d is the case where one lead 33r is provided at the front or rear, and two Liu wheels 33s are provided at the rear or front. As described above, the present invention provides a movable wall hanging wheel that runs on a hanger rail installed on the ceiling, in which a pair of rotating main wheels having different outer diameters are provided on the left and right sides of the hanging wheel body, and a branch portion of the hanger rail is provided with a pair of rotating main wheels having different outer diameters. A main guide rail that interferes with the large-diameter rotating main wheel is installed on the main rotating main wheel, and movable wall hanging tools are placed on the axis of the rotating main wheel. In addition to attaching a pair of rotating sub-wheels to each of the rotating wheels, one of the rotating wheels is provided with a guide collar that rotates integrally with the rotating wheel, and the outer surface of the rotating main wheel is attached to a rotating sub-wheel. It is installed in a position that protrudes outward from the outer surface of the ring, and is inserted into the guide groove of the hanger rail at a position eccentric back and forth from the movable wall hanger at the bottom of the hanger to guide the hanger body along the hanger rail. This is a bending travel control device for a movable wall hanging wheel, which is characterized in that one guide wheel is attached to each of the movable wall hanging wheels, so that even if the bending radius is small, the hanging wheel can move along the main guide rail at the bending rail section. Since other unstable movements are suppressed, collisions between the hanging tool and the hanger rail and unstable movement of the guide rollers are prevented, and the moving state of the hanging wheel is stabilized.

Further, the present invention provides a pair of rotating sub-wheels arranged on the sides of the main body of the hanging wheel before and after the rotating main wheel provided at the center of the hanging wheel, and rotates integrally with one of the nine rotating wheels of the rotating grave. Since it is a guide wheel equipped with a guide collar, it is possible to apply a large rotational moment to the hanging wheel through interference with the guide rail, and the hanging wheel can run extremely smoothly at the bending part of the hanger rail. At the same time, it did not have flanged wheels on both the front and rear of the hanging carriage like the six-wheeled trolley of the sub-chassis, but only the front or rear of the hanging carriage was considered to be the leading wheel with flanges. It is possible to avoid the inconvenience of the above-mentioned brim digging into the edge of the hanger rail or causing twisting, and 6 pieces (3 pieces each on the left and right) on the bending rail.
This makes the running condition of a hanging wheel with wheels extremely smooth.
