Description

[Detailed description of the invention] [Field of industrial application] This invention is a method for changing the path of the panel to go straight, turn right, turn left, etc. at the intersection of guide rails laid on the ceiling to support the partition panel. Regarding equipment.

[Conventional technology]

For example, in the case of a runner that uses ball-shaped rolling elements as rolling elements and is movable in all directions, it is possible to turn right or left at right angles at intersections of guide rails. However, when the runner 44 is formed in a T-shape with a pair of left and right roller rows each consisting of a group of 4 to 8 rollers as shown in Fig. 2, the front and rear length of the runner is larger than the width of the guide rail. Therefore, you cannot turn right or left at right angles. Therefore, by connecting the intersecting guide rails with an arc-shaped turning path,
It is necessary to guide the runner.

For example, Japanese Patent Publication No. 58-43550 discloses a conventional device for mechanically changing the course at the intersection of guide rails. It is equipped with a straight path that intersects in a criss-cross pattern, and four arcuate turning paths that connect adjacent straight paths. The two sides are closed with guide fittings, and one of the following routes is selected: go straight, turn right, or turn left. Guide fittings are installed at a total of four locations at the connection points with the guide rails of each straight path, and the switching operation is performed using a forward/reverse motor, a link,
This is done with arms etc.

[Problems to be solved by the invention] As mentioned above, in devices that mechanically perform switching operations using a motor as a drive source, transmission members such as links and arms that transmit operating power, and systems for positioning the switching posture are required. A position detection member is required, etc.
Overall, the number of parts is large and the structure is complicated, which tends to increase weight and cost.

A turning path that guides the partition panel in a right-turn or left-turn direction is provided outside the center of the intersection.
Therefore, it should be noted that when the partition panel moves at a high speed when passing through the direction change path, a large rotational moment acts on the path change device. In particular, large panels used in banquet halls, exhibition halls, etc. weigh up to several hundred kilograms, so if the moving speed is high, an excessive rotational moment will act on them. This point was a cause for concern with the previous conventional device.

An object of the present invention is to simplify the structure of a route switching device and reduce its manufacturing cost.

Another object of the present invention is to obtain a strong and robust steering device capable of resisting the rotational moment when the panel passes.

[Means for solving problems]

In the present invention, the course of the panel is changed by rotating the rotary base 6, which is provided with a straight path 12 and a direction change path 13. However, the rotary base 6 is directly driven to rotate by the rotary solenoid 16, which is cheaper in cost than a motor, thereby simplifying the structure. Also,
The present invention is characterized in that a locking means 24 is provided to prevent rotation of the rotary base 6 in order to resist the rotational moment generated when the panel passes through the panel.

Specifically, as shown in FIG. 1, a rotary base 6 is horizontally rotatably supported on a fixed base 5 connected to the ceiling wall 1, and a straight path 12 having the same cross-sectional shape as the guide rail 2 is provided on the lower surface of the rotary base 6. A turning path 13 curved in an arc shape is attached. Then, with a rotary solenoid 16 having a constant operating angle,
The rotary base 6 can be moved in an articulated manner by a fixed angle in a fixed direction via a one-way clutch 22, and the rotary base 6 is mechanically held locked by a locking means 24 after each feeding operation is completed. It is. Here, it is preferable that the effective operating angle of the rotary solenoid 16 is set slightly larger than the crossing angle of the guide rail 2 or an angle obtained by equally dividing the crossing angle.

[Effect]

The rotary solenoid 16 reciprocates within a certain angular range and outputs rotational torque in one direction. The rotary solenoid 1
6, the rotary base 6 is fed by a fixed amount in an articulated manner, and then the rotary base 6 is moved by the locking means 24.
By holding the lock, the straight path 12 or the diversion path 13 can be switched to a predetermined connection position. Therefore, the rotary base 6 can be directly driven and positioned by the rotary solenoid 16 without requiring a position detection member, a power transmission member, etc. for positioning.

〔Example〕

1 to 5 show a first embodiment of the present invention.

In FIG. 2, the course switching device 3 of the present invention is disposed at an intersection C of guide rails 2 installed on a ceiling wall 1. This path switching device 3 includes a disk-shaped fixed base 5 fixed to a structure connected to a ceiling wall 1 via a bracket 4, and a rotary base 6 supported horizontally rotatably on the lower surface of the fixed base 5.
It is equipped with

In FIG. 1, the fixed base 5 consists of a thrust ring 7 having an L-shaped cross section and a base plate 8 that closes the upper opening of the thrust ring 7. Small-diameter steel balls 10 are lined around 9 to rotatably support the lower surface of the periphery of the rotary base 6.

A guide rail 2 is provided on the underside of the rotary base 6.
Straight path 12 formed of rail material with the same cross-sectional shape as
and two turning paths 13, 1 for right or left turns.
3.

In FIG. 3, the straight path 12 is fixed so as to cross the center of the lower surface of the rotary base 6, and the guide rails 2a, 2b, and 2 face each other at the intersection C.
Connect c and 2d. Each of the deflection paths 13 is bent into an arc shape, and is fixed to the rotary base 6 so that the curved side surfaces thereof face each other in a symmetrical posture with the straight path 12 in between. With this route arrangement, both end connection ports 13a, 13a of each diversion route 13
open at positions that are out of phase by 45 degrees in the circumferential direction with respect to the connecting ports 12a, 12a at both ends of the straight path 12.

In FIG. 1, a rotary solenoid 16 is fixed to the center of the base plate 8 via a cylindrical bracket 15. The bracket 15 is fitted into a mounting hole 17 formed through the base plate 8 and secured with a bolt.
Its lower end opening faces the rotary base 6. A connecting shaft 18 that inherits the rotational torque of the rotary solenoid 16 is fixed to the upper center surface of the rotary base 6, and the two upper and lower parts of this shaft 18 are connected to the bracket 1.
It is rotatably supported by bearings 19, 19 attached to the inner cylinder wall of 5. A connecting hole 20 is formed from the upper end of the connecting shaft 18 toward the base end, and the output shaft 21 of the rotary solenoid 16 is fitted into the connecting hole 20. Then, a one-way clutch 22 similar to a needle bearing having a roller as a transmission element is fitted and fixed near the open end of the connecting hole 20, and the output shaft 21 is inserted into the shaft hole.

As a result, only the operation of the rotary solenoid 16 when the rotational torque is output is transmitted to the rotary base 6. Although not shown, the rotary solenoid 16 includes a return spring for self-returning to the starting position and a positioning stopper. During this return operation, the roller of the one-way clutch 22 idles, cutting off the power. Figures 2 to 4
In the figure, the rotary solenoid 16 rotates by an effective operating angle of 45 degrees or more, preferably 50 degrees, while outputting rotational torque in the direction of arrow A.

A locking means 24 is provided to prevent the rotary base 6 from overrunning and to hold the rotary base 6 fixedly in a non-rotatable manner against the rotational moment acting on the deflection path 13 when the panel passes through.
are provided near the periphery of the base plate 8.

In FIG. 1, this locking means 24 includes a lock shaft 26 that is vertically movably supported in a guide hole 25 that passes through the base plate 8, and a lock hole 27 that is formed in the rotary base 6 and into which the lock shaft 26 is fitted.
It consists of a linearly operated solenoid 28 that operates the lock shaft 26 up and down. A total of eight lock holes 27 are formed at 45 degree intervals in the circumferential direction of the rotary base 6 as shown in FIG.
7a (see FIG. 5). Lock shaft 2
A spring receiving nut 30 is screwed into the middle of the compression coil spring 26, and the spring 29 is mounted between the nut 30 and a stay 31 that supports the upper end of the lock shaft 26. A collar 32 that defines the depth of engagement of the lock shaft 26 with the lock hole 27 is formed projecting from the lower end side of the lock shaft 26.

The solenoid 28 is fixed to the base plate 8 with its output shaft 34 moving up and down, and the output shaft 34 and the lock shaft 26 are connected via a swing link 35. 36 is a bracket that supports the swing link 35. An operating shaft 37 is provided at the lower end of the output shaft 34 in order to release the lock shaft 26 during a power outage.
is fixed to protrude from the lower surface of the fixed base 5, and an operating fitting 38 is fixed to the tip thereof.

The operation command for the path switching device 3 is transmitted by an ultrasonic transmitter 40 as shown in FIG. 2, and is transmitted via a receiver 41 embedded in the ceiling wall 1 to operate a control circuit (not shown).

In the figure, reference numeral 43 is a partition panel, and 44 is a runner that runs within the guide rail 2.

Next, the operation will be explained. In a steady state, the rotary base 6 is fixed non-rotatably by the locking means 24. At this time, each guide rail 2
a, 2b, 2c, and 2d are connected to either the straight path 12 or the two turning paths 13, 13.

For example, as shown in FIG.
When it is desired to move the partition panel 43 on the side to the guide rail 2d side, the ultrasonic transmitter 40 transmits an operation command. The control circuit that receives the operation command via the receiver 41 first operates the solenoid 2 of the locking means 24.
8 is energized to draw in its output shaft 34, and the lock shaft 26 is pulled out above the lock hole 27.
Next, the rotary solenoid 16 is energized and the output shaft 21 rotates. The rotational movement of the output shaft 21 is transmitted to the connecting shaft 18 via the one-way clutch 22,
The rotary base 6 rotates in the direction of arrow A. After the rotary solenoid 16 is activated, the power supply to the solenoid 28 is stopped, and the lock shaft 26 is returned downward by the spring 29 and comes into contact with the upper surface of the rotary base 6.

As the rotary base 6 rotates, the straight path 12 that had previously connected the opposing guide rails 2a, 2b separates from both guide rails 2a, 2b, and the connection port 13a of each turning path 13, 13, 13
a, 13a, 13 are guide rails 2a, respectively.
and 2d, and approaches 2b and 2c. When the rotary solenoid 16 rotates to near the end of its swing stroke, the lock shaft 26 fits into the groove 27a and its tip sinks below the upper surface of the rotary base 6, as shown in FIG. Therefore, when the rotation amount of the rotary base 6 reaches 45 degrees from the starting position, the lock shaft 26 forcibly stops the rotation of the rotary base 6 that is in contact with the inner wall on the opening edge side of the lock hole 27, and at the same time The lock shaft 26 falls into the lock hole 27 due to the urging force of the spring 29. This reliably prevents the rotary base 6 from overrunning due to inertia. When the rotary base 6 is stopped, the connecting ports 13a of the direction changing paths 13, 13 are connected to the guide rails 2a, 2d and 2b, as shown in FIG.
2c, by moving the partition panel 43, the runner 44 is guided to the direction change path 13 and transferred to the target guide rail 2d.

The rotational torque of the rotary solenoid 16 has a characteristic that it is maximum at startup and gradually decreases as the rotation angle increases. The position rotated 50 degrees from startup is almost zero. Therefore, it is possible to rotate the rotary base 6, which is relatively heavy, from a stationary state without any difficulty, and since the operating force gradually decreases toward the end of the operating stroke, the inertia of the rotary base 6 This is advantageous in that it can suppress as much as possible, and the impact caused by the forced stop of the locking means 24 can be reduced.

Thereafter, by rotating the rotary base 6 as necessary, the guide rails 2 to be moved can be connected to each other by the straight path 12 or the direction change path 13. In addition, when the two turning paths 13 are provided at symmetrical positions across the straight path 12, it is convenient because the number of operations of the rotary base 6 can be reduced when turning right or left from any guide rail. .

[Another embodiment example]

6a, b, and c show examples of different embodiments of the guide route in the rotary base 6, respectively.

In FIG. 6a, one straight path 12 and one diversion path 13 are provided on the rotary base 6.

In FIG. 6b, the straight path 12 is arranged so as to intersect the two turning paths 13 at the same time.

In FIG. 6c, one straight path 12 and two turning paths 13, 13 are arranged in a Z-shape with left and right directions reversed.

In this way, the guide path provided on the rotary base 6 can be freely set as necessary, so there are no restrictions on its shape or arrangement structure. Further, the intersection C to be installed may be a three-way intersection.

The locking means 24 may be of any type as long as it can lock or release the rotary base 6 in a non-rotatable manner, and its structure can be arbitrarily selected.

Regarding the lock hole 27, as shown by the imaginary line in FIG.
The engaging piece 27b, which the tip of the engaging piece 27a contacts, may be fixed, and in this case, the groove 27a can be omitted.

[Effect of idea]

As explained above, in the course switching device of the present invention, the rotary base 6 can be fed in one direction in an articulated manner using the rotary solenoid 16 as a drive source, and each feeding operation is synchronized with the feeding movement of the rotary solenoid 16. The course is changed by mechanically fixing and holding the rotary base 6 with the locking means 24. Therefore, compared to conventional path switching devices that use a motor as a drive source, drive transmission members and operation position detection members can be omitted.
Overall, the structure can be simplified and the manufacturing cost of the path switching device can be significantly reduced.

In addition, since the rotary base 6 is mechanically kept locked by the locking means 24 except when changing the course, even if a large rotational moment acts on the rotary base 6 when turning right or left, This has the advantage that the rotary base 6 can be reliably positioned and held by sufficiently resisting the moment, and a course switching device that is strong, sturdy, and has excellent durability can be obtained.
