Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides freedom in controlling the traveling direction of a moving wall hanging vehicle (hereinafter referred to as a hanging vehicle) that enables smooth running of the hanging vehicle at orthogonal sections (intersections) of hanger rails, which are the travel tracks of the hanging vehicle. The present invention relates to a method for controlling the traveling of a suspended vehicle with high efficiency.

Figures 1(a) and 1(b) show the running state of an example of a conventional hanging wheel (
The hanging wheel is approaching the orthogonal part of the hanger rail).

In the figure, 1 is the suspension main body, which has a vertical movable wall suspension shaft 2 (a shaft for suspending the movable wall downward) below the center, and two vertical wheels SA on each of the four sides, front, back, left and right. , 3a, 3b
, 3b, 3c, 3c, 3a, 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 shown cut at the central horizontal plane in FIG. 1(a), and the lower running plate 4a
However, as shown in Fig. 1(b), the actual product consists of the lower running plates 4a, 4a, the vertical side walls 4 following these, and the horizontal side walls connecting the side walls at their upper ends. upper wall 4c
and a guide rail 4J provided continuously in the longitudinal direction at the center of the lower surface of the upper wall 4°. (travel surface), the suspension wheel main body 1 travels 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 top surface of the running plate 4a.
This is to prevent contact interference between the two planes when the suspended wheel main body 1 is traveling.

There are four guide rollers 61.6I on the upper surface of the hanging wheel body l.
, , 6c, and 6a are arranged at regular intervals, and as shown in the figure, they roll into contact with the left and right sides of the guide rail 4c+ through a minute gap, and the hanging wheel main body 1 is guided by the guide rails 4J and moves straight. maintain the condition.

Then, when the hanging wheel main body 1 moves straight in the direction of arrow X, for example, and approaches the orthogonal part shown in the first figure, the front wheel 31I of the wheels 3a and 3b perpendicular to the running direction moves to the cut E ( The suspension shaft 2 passes over the groove, and the load applied to the suspension shaft 2 causes the suspension wheel body 1 to tilt.

Then, the wheel 38 that fell off at the cut E through which the hanging wheel moves forward collides with the traveling plate and gives an impact to the hanging wheel and the moving wall. Furthermore, when the hanging wheel advances further and reaches the center position of the orthogonal part of the hanger rail as shown in FIG.
The vertical wheels that were in rolling contact with the top surface of 1 fit into the 5-meter perpendicular direction to the running direction, and as a result, all the vertical wheels 3m
3J to 3J fit into the arcuate grooves 5 in the longitudinal and lateral directions, and the movement of the hanging wheel is temporarily stopped.

Therefore, if a force is applied to the hanging wheel main body 1 in any direction from front to back, right or left, at this central position, the hanging wheel main body 1 will start moving in that direction.
It is possible to change the running direction to any direction.

However, as mentioned above, such hanging wheels can freely change the direction of travel, making them extremely practical, and the suspension force is strong because the load is carried by a large number of vertical wheels.
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 stopped state (the state where the entire hanging wheel sinks by the depth of the groove 5).
When starting a new suspended vehicle, the vertical wheels in the traveling direction must escape from the groove 5 and ride on the flat surface (traveling surface) of the traveling plate 4a. This a5
The depth is such that the vertical wheel (3°, 3b) perpendicular to the traveling direction of the hanging wheel, which swings slightly from side to side, touches the running plate 4a while traveling straight.
It is necessary to have a deep R surface with a certain degree of scale so as not to interfere with the upper surface, and since the vertical load acting on each hanging wheel usually ranges from several hundred kg to several tons, it is necessary for the vertical wheels to move through the groove 5. It becomes a huge resistance to overcome and 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 attic, but rather by pushing the movable wall hanging from the hanging wheel. If the resistance due to such grooves 5 is large, it may become practically impossible to move the hanging wheel from the part orthogonal to the hanger rail.

Therefore, the object of the present invention is to prevent the hanging wheel from receiving impact even at the center of the orthogonal part of the hanger rail.

The aim is to achieve a clean running condition so that the hanger rail can cross the cut in the hanger rail without much effort and can be started with a small force. , each of 1 or 2 vertical wheels are attached at a height touching the same horizontal plane, and a horizontal ball holder is mounted on a vertical shaft provided at the center of the suspension wheel body, and a horizontal ball holder is mounted on the lower surface of the member. An auxiliary wheel comprising a plurality of balls that roll in contact with each other is attached, and correction rails parallel to the running surface are installed at the four corners of the orthogonal part of the hanger rail, which has a running surface that forms the running track of the vertical wheels. is installed, and when the hanging wheel main body is running on the straight section of the hanger rail, the vertical wheels contact the running surface of the hanger rail and bear the load applied to the hanging wheel main body, and the hanging wheel main body runs on the orthogonal part of the hanger rail. The purpose of the present invention is to provide a traveling control method for a movable wall hanging wheel in which the ball of the auxiliary wheel rolls into contact with the upper surface of the auxiliary rail to support the load applied to the hanging wheel body when the hanging wheel is about to approach.

Next, embodiments embodying the present invention will be described with reference to the accompanying drawings starting from FIG.

is fixed to the tip of the The upper surface of a member 26 is in contact with the lower surface of the flange-shaped head 24, and a plurality of balls 27 are rotatably attached to the lower part of the member 26 by a retainer 28. is,
The ball receiver is constructed by sandwiching one surface of the member 26 and the lower surface of the inner ring of the retainer 28 between the flange-like head 24 and the protrusion 29 of the sleeve 25. It is attached to a part of the suspension shaft 18 in a state where it is in contact with the lower surface of the suspension shaft 26 . l-ball 27. In the ball bearing, a thrust bearing-like auxiliary wheel 20 is constituted by a member 26 and the like.

Further, the hanging shaft 18 has a rotatable vertical wheel 30 at the lower part of the hanging wheel main body IO. As shown in FIG.
The hanging shaft 18 is inserted into the groove 31 which is a cut in the hanger rail through which the hanging shaft 18 passes through the middle of the side wall 32 of the groove 31.
By interfering with 32, the hanging wheel main body 10 is prevented from tilting in the left-right direction.

Further, horizontal guide wheels 33 are rotatably attached to each corner of the upper surface of the hanging wheel main body 10, and these guide wheels 33 are connected to the guide wall 3 of the hanger rail 16.
4, the hanging wheel main body 10 can travel straight along the hanger rail 16.

As shown in FIG. 2, the above-mentioned hanger rail 16 has a roughly C-shaped cross section and includes a top plate part 35 for attaching to a structural member in the ceiling, and a connecting part 3 connected diagonally downward from the left and right ends of the top plate part 35.
6, the vertical guide walls 34, 34 connected to each connection 36, 36, and the vertical wheels 12. ~12
a and vertical auxiliary wheels 15. ~15. left and right running plates 37, each having on its upper surface the running surface 17 forming a running track of 1; '37, the running plate 37 and the connecting part 36 are connected, and the vertical wheel 1
side walls 38.3B for accommodating the wheels 28 to 12a;
The side walls 32, 32 of the groove 31 form the guide walls of the groove 31.

Therefore, for example, in the state shown in FIG.
When traveling straight along the hanger rail 16,
Vertical wheels 12c, 12d and vertical secondary wheels 15c, 15a parallel to the running direction are on the running surface 17.1 of the running plate 37.37.
7, the load applied to the suspension wheel main body 10 via the suspension shaft 1B is supported by these wheels 6+11i1, and the vertical wheels 12□, 12 in the direction perpendicular to the running direction
The vertical auxiliary wheels 15 and 15b are all located on the groove 31 and away from the running surface 17. Therefore, the vertical wheels and vertical auxiliary wheels that are perpendicular to the traveling direction do not interfere with the /\ger rail 16, and the hanging wheel main body 10 can smoothly travel in the direction perpendicular to the plane of the paper in FIG. 2.

As described above, the face wheels 30 interfere with the side walls 32 of the grooves 31 to prevent the hanging wheel main body 10 from tilting in the direction parallel to the paper plane of FIG. The hanging wheel main body 10 is guided so as to run straight along the hanger rail.

Next, the structure of the orthogonal part of the hanger rail and the running state of the hanging wheel in this part will be explained with reference to the drawings from FIG. 7 onwards.

As shown in FIG. 8, the hanger rails 16 are orthogonally connected in a cross shape around a top plate 39 attached to a structure in the attic. The bolt holes 40 are for inserting bolts for attaching the hanger rail into the top plate 39. The top plate 39 also has numerous bolt holes 4 for attaching an auxiliary rail 41 (see Figures 7 and 10) divided into four parts.
2 is formed, and auxiliary rails 41 are attached to the lower surface of the top plate 39 symmetrically in the front and back.

At each corner of the top plate 39, a mounting part 45 is formed for attaching a running aid plate mounting pro-tsuku 44 for supporting the running aid plate 43 shown in FIG. A bolt hole 46 for screwing a plate mounting pro-tsuku 44 is provided.

As shown in FIG. 7 and FIG. 1θ, the auxiliary rail 41 is
1 in the horizontal direction of a regular square plate that directly contacts the top plate 39;
- a cotton board 47, a support plate 48 disposed below the upper board 47 and parallel to the two-part board 47, and a vertical support plate 48 with a cross-section that connects these ten cotton boards 47 and support plate 48; A connecting member 49 in the direction, and a lower end of the connecting member 49 is formed, and the support plate 48
It is composed of a guide piece 50 that protrudes further downward than 1.
The F cotton board 47 covers the lower surface of the top plate 39 without any gaps, as shown in FIG. As shown in FIG. 2, cross-shaped grooves 51 are formed so that the suspension shafts 18 can pass through the support plate 48 without coming into contact with them, and are arranged at regular intervals.

The traveling aid plate 43 is fixed to the four orthogonal corners of the hanger rail 16 like the support plate 48, but it is fixed to the lower end portion of the traveling aid plate mounting block 44 by a port 52, and the attached state is fixed. In the travel auxiliary plate 43
is attached at a height such that its upper surface is flush with the running surface 17 of the hanger rail, and its tip 53 is
Since it protrudes from the running plate 37 of the hanger rail 16 in the direction of the groove 31' between the left and right running auxiliary plates 43,
Vertical wheels 12 perpendicular to the upper surface of the travel aid @43 and the traveling direction of the suspended vehicle that has traveled straight ahead. There is a risk of interference with the lower end surface of. Therefore, a groove 54 having an arcuate cross section and an appropriate depth is formed in the upper surface of the travel assisting plate 43 in the travel direction of the suspended wheel.

The height of the mounting of the support plate 4B is as shown in FIG. The height is set such that the hanger body 10 does not come into contact with the upper surface of the support plate 48 and a slight gap of, for example, lIm is created between the two, and the hanger body 10 approaches the orthogonal part of the hanger rail 16 and is parallel to the running direction. Vertical wheels are installed in the groove 5.
4 or the groove 3 between the left and right travel auxiliary plates 43
When passing over 1', the ball 27 comes into contact with the upper surface of the support plate 48, so that the load of the moving wall is supported by the support plate 48.

The state in which the vertical wheel is thus fully depressed into the groove 54 and the ball 27 is in contact with the upper surface of the support plate 48 is shown on the right side of FIG. 6 and in FIG. At this time, the height of the traveling auxiliary plate 43 and the groove 54 are adjusted so that a gap of about 0.5 dragon is further interposed between the depressed vertical wheel and the groove 54.
Adjust the depth.

Therefore, when the ζ hanging wheel main body 10 is running on the straight part of the hanger rail 16 as shown in the left half of FIG.
As described above, the balls 27 do not come into contact with the upper surface of the support plate 48, and there is a slight gap between them. The vertical wheels 1 were rolling on the upper surface of the running auxiliary plate 43, which is on the same plane as the running surface 17 of the
2°, 12a slightly falls into the groove 54, and as the hanging wheel main body 10 descends, the ball 27 comes into contact with the upper surface of the support plate 4, and the load of the movable wall applied to the hanging wheel main body 10 is supported by the auxiliary wheels 20. Ru. At this time, as shown in the right half of FIG. 6, there is a slight gap between the vertical wheels 12c, 12a that have fitted into the grooves 54 and the grooves 54, so that the travel assisting plate 43 This vertical wheel 12. is not subject to the load of the moving wall. Due to the slight fall of the vertical wheels, all the vertical wheels fall into the grooves 54, and the operator can sense that the hanging wheel main body 10 has come to the center of the orthogonal part by applying resistance to the movement in the front, rear, right and left directions. . In this way, when the hanging wheel main body 10 reaches the center of the orthogonal part of the hanger rail 16, the guide piece 50 and the guide ring 33
The hanging wheel main body 10, which could not move in the direction perpendicular to the running direction due to interference with the guide wheel 33
However, since it is freed from interference with the guide piece 50 at the center of the orthogonal part, it is in a state where it can run in any direction, front, back, left, or right, and the operator can push the hanging wheel main body in any direction. At this time, the vertical wheels will climb over the grooves 54 of the traveling support plate 43, and the operator will feel some resistance, but most of the load of the moving wall will be transferred to the support plate 48 through the balls 27 as described above. Since the vertical wheels 12 are not completely inserted into the grooves 54, they can be easily escaped from the grooves 54, and the vertical wheels are located between the auxiliary running plates 43, 43. This avoids inconveniences such as falling into the groove 31' and impacting the hanging wheel.

As described above, the present invention has a structure in which one or more vertical wheels are attached to the west side surface of a suspension wheel body having a substantially right-angled hexahedral shape, each at a height that touches the same horizontal plane, and at least one vertical wheel is attached to a vertical shaft provided at the axis of the suspension wheel body. , the horizontal ball holder is attached with an auxiliary wheel comprising a member and a plurality of balls that transfer in contact with the lower surface of the member, while the hanger rail has a running surface forming a running track of the vertical wheel. At the four corners of the orthogonal part, correction rails parallel to the running surface are installed, and when the hanging wheel body is running on the straight part of the hanger rail, the vertical wheels marked L roll into contact with the running surface of the hanger rail, and the hanging wheel body When the hanging wheel body approaches the orthogonal part of the hanger rail, the balls of the auxiliary wheels roll into contact with the upper surface of the auxiliary rail to support the load applied to the hanging wheel body. Since this is a characteristic running control method of a moving wall hanging vehicle, the vertical wheels at the orthogonal part of the hanger rail can maintain an extremely smooth running condition without falling into the cut (groove) of the hanger rail. At the same time, the traveling direction can be freely changed to any direction, and the degree of freedom in transporting and arranging the movable wall is improved at once.

In addition, as a suspension means for a hanging car, there is a system that uses only the auxiliary wheels used in the embodiment of the present invention and does not use vertical wheels.
Even in the arranged state, the entire moving wall C load will act on the training wheels, but if you constantly apply a high load to the training wheels, which are not suitable for high loads because they are originally point contacts, the training wheels will be damaged early. It is not practical for high-load applications because it wears out, makes a lot of noise, and damages the hanger rail.

In this respect, as described above, in the present invention, the vertical wheels support the high load of the moving wall when normally placed, fixed, or traveling straight, and the auxiliary wheels temporarily support the load only when the wall comes to the orthogonal part of the hanger rail. Since it is supported, damage to the auxiliary wheels is hardly a problem, and the hanger rail does not wear out, so inexpensive aluminum hanger rails can be used, making it extremely practical in terms of both durability and cost. This is a control method.
