Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a control device for a monorail point device, and is particularly suitable for controlling a monorail point device that uses a swing arm for point operation. It is related to the device.

[Conventional technology]

Conventionally, in a monorail track, the depot parking line and the main line were connected by a switch shown in, for example, Japanese Patent No. 490,849. When positioning the point girder in the position corresponding to the fixed girder in the point equipment mentioned in the review, the driving force is cut off before the stop position, and the point girder is placed in a position corresponding to the stop position of the point girder. This was done by placing the point girder against the stopper.

[Problem that the invention seeks to solve]

In the above-mentioned prior art, the switch operation is performed by associating the switch girder with two fixed girders, and the positioning is performed by a stopper at the switch position corresponding to each fixed girder. was. By the way, in recent years, the site area has been reduced as much as possible,
At the same time, there is a growing demand for garages that can store many vehicles.
As a result, one point machine has become necessary for one orbit, three or more orbits. In such a point device, the point girder cannot be positioned by applying it to a stopper as described in [1], and a special device for positioning, that is, a rod driven by a telescopic cylinder, is used as the basis. A means for inserting and stopping the device into a hole provided in the section is required, which poses problems such as a complicated configuration.

The object of the present invention is to have a simple configuration.

It is also desirable to provide a control device for a monorail point machine that can accurately position the point girder.

[Means for solving problems]

The above object is to provide a point machine that performs a point using a rotating arm, a stop position detecting means for detecting a state in which the rotating arm is positioned in a point direction, and a stop position detecting means for detecting a point position by a detection output from the stop position detecting means. A device consisting of a controller that stops the operation of the driving means of the point girder [Function] When the point girder is rolled by a swing arm, the swing angle of the swing arm and the displacement of the point girder are controlled. is equivalent to 6 quadratic functions. That is, since the engaging end of the swing arm where the engaging means is provided moves in an arc, when the motion of the engaging end is mechanically converted into movement of the point girder, the relationship becomes a quadratic function. In detail, when the swing arm turns from a position perpendicular to the moving direction of the point girder to a position parallel to it, the amount of movement #J of the point girder relative to the turning angle gradually decreases, and in the parallel position S Stop once. When the swing arm is positioned parallel to the moving direction of the rolling girder, that is, the rolling direction, the displacement of the swing arm with respect to the swing angle becomes the smallest. Therefore, if the drive system performs the stopping operation with the swing arm parallel to the rolling direction, the error associated with the operation of the drive system can be minimized as an error in the rolling direction.
Accurate positioning of point girders is possible.

〔Example〕

Hereinafter, one embodiment of the present writing jar will be explained with reference to FIGS. 1 to 3. In one cause, 1,2.

Reference numerals 3 and 4.5 are fixed girders, which are installed at a distance greater than a distance that will not cause contact with the monorail vehicle when the monorail vehicle passes through each of them. A guard is installed between the fixed girders 1 to 5 and the fixed girder A provided opposite thereto. Reference numeral 10 denotes a switch girder constituting the switch, which is installed so as to be movable in the horizontal direction in a range corresponding to the fixed girders 1 to 5 centered on the fixed girder A side.

Note that the point girder 10 is usually constructed by connecting a plurality of pieces so as to be rotatable in the horizontal and vertical directions, and
The end of the vehicle is supported by a bogie 17 that runs on rails 18 provided above. 7, 8.9 is the old writing shift digit 1
This is a groove guide arranged on the groove base surface 6 corresponding to the position corresponding to each of the fixed girders 1 to 5 of 0, that is, the central part at the point position. 11,12.

Reference numeral 13 denotes a swing arm that is swing-driven by a drive device 141 attached to the lower surface of the point girder 10, and has a swing arm 141 at its tip.
A roller 5 is attached as an engaging means for engaging the I'iT groove guides 7, 8.9. Reference numeral 15 denotes a shaft protruding from the driving device wLl4 for driving the swing arms 11 to 13, and the swing shafts 11 to 13 are attached to this shaft. 16 is an electric motor attached to the drive device l4.

Next, the control system in the IIIT transfer point IA device will be explained. 19 g, 19 b, 19 c,
19 d and 19 e are conversion check relays provided corresponding to fixed girders 1 to 5, each having an a contact and a b contact. 19a and 19a, which are the a contacts of the relay, respectively, when facing each other.

19ha, 19ca, 19da, and 19ea are closed, and 19ab is a b contact.

19bb, 19cb, 19db, 19eb are opened. The conversion inspection lever L/-19a, 19 is provided on the trolley 17 and attached to the foundation surface 6.
b, 19 c, 19 d, 19
This is an operation piece for operating e. 21a, 2lb,
21c.

Reference numeral 21d indicates a position detection relay provided on the base surface 6 between each of the fixed girders 1 to 5, and includes the conversion check relays 19a, 19b, 19c, and 19.
It has an A contact that operates between the operating ranges of d and 19e, and the ends of the operating ranges are connected to the conversion check relays 19a to 19.
It slightly overlaps with the operating range of e. n is the position detection relay 21a.

This is an operating piece provided on the trolley 17 to operate 2lb, 21c, and 21d within the above-mentioned range.

KU is a swing arm detection relay which constitutes a stop position detection means and is provided on the lower surface of the track girder 10 so as to be able to come into contact with the operating arm provided on the shaft 15 that drives the n rotation shafts 11 to 13. The arrangement relationship with the actuating piece is taken into consideration so that when the points 11 to 13 face in the moving direction of the point girder 10, that is, in a direction parallel to the point direction, the b contacts thereof operate.

Therefore, the operating range of the swing arm detection relay n is as follows.

Since it is set on the circumference of the swing arms 11 to 13, when R rotations 11 to 13 operate parallel to the point direction, it is extremely difficult to convert it to the movement range of the point girder 10. The range is narrow.

In such a configuration, an example of a circuit configuration for moving the switching girder 10 from the position corresponding to the fixed girder 1 to the other fixed girders 2 to 5 will be described. That is, the circuit configuration is as shown in FIG. 5, and the operating status of each relay is as shown in FIG. 4. In addition, in FIG. 5, 25A and 25B.

25C and 25D are command relays for each operation command from fixed digit 5 to fixed digit 2. Regarding the operating state, only the transition to the fixed girder 3 will be explained in the aforementioned FIGS. 4 and 5, and the transition to other locations will be omitted.

First, when switching the switch girder lO to the fixed girder 3, the command relay 2 is operated by a separately provided switch command device.
5C is closed. At time 2, the swing arm detection relay n is a B contact and is open, but the conversion check relay 19cb is closed. In addition, since the conversion check relay 19aa is closed and the circuit is configured, the switch girder 10 is connected to the fixed girder 3.
move towards. Then, the point digit lO is the fixed digit l
When the switching check relay 19 approaches the position where it is removed from the
Directly exposed to the opening of aa, the position detection relay 21a closes, and the energized state of the circuit is maintained. Further, when the point girder 10 moves to a position corresponding to the fixed girder 2, the position detection relay 21a switches to direct contact, which opens the inspection relay 19.
ba is closed, and this operation maintains the energized state of the circuit. Therefore, the point girder 10 continues to move, and the switch girder 10 continues to move, and when the H conversion check relay 19ha is opened, the switch girder 10 continues to move.
T! lJ! The knowledge relay 21b is closed, and the conversion checking relay 19ca is closed until the fixed digit 5 corresponds to the complete number. At this time, the conversion check relay 19cb, that is, the b contact is open, and in this state, the point when the point girder 10 completely corresponds to the fixed girder 3, that is, the point parallel to the direction in which the swing arms 11 to 13 rotate At the time when the rotation arm detection relay n is activated, its b contact is opened.

Therefore, the energization state of the circuit of the command relay 23C is cut off, and the point girder 10 is stopped. In this way,
The switch girder 10 completes the switch from fixed girder l to fixed girder 3. An example of the control circuit for switching from the fixed digit 1 to the other fixed digits 2 to 5 is shown in Figure 5; The accompanying control circuit is also configured in substantially the same way. Note that the explanation thereof will be omitted here.

According to configuration 2, compared to the case where the movement status of the switch girder 10 itself is detected by the conversion check relay 19aa = 19eb and the position detection relays 21a to 21d, an additional 1M rotation detection relay phantom is provided. By doing so, reliability and detection accuracy can be improved. That is, the swivel arm detection relay operates in accordance with the 11th to 130th orders of the swivel arms, and the swivel arms 11 to 13 are connected to the point girder 1
As the point approaches a position parallel to the point direction of 0 (as compared to its turning angle), the point movement decreases in a quadratic function relationship.

That is, in the vicinity where the swing arms 11-13 coincide with the point direction, the amount of movement of the switch girder 10 becomes very small, and the movement of the swing arm detection relay n, which detects the operating status of the swing arms 11-13, becomes extremely small. Even if an operational error occurs, the error becomes very small in the operating direction of the point girder 10, so that the detection accuracy of the point girder 10 can be improved. Moreover, the above-described accurate rolling operation can be performed with a relatively simple configuration in which the swing arm detection relays n are provided corresponding to the swing arms 11 to 12.

Therefore, there is no need to stop the switch girder 10 by hitting a stopper or the like (it is possible to switch to a plurality of fixed girders as described above).

Further, by detecting the position of the point girder 10 using a plurality of detection means, it is possible to confirm malfunction, etc., thereby improving safety.

In addition, in the above embodiment, an example of transfer to five fixed girders was explained; however, the present invention is not limited to this, and as long as the transfer is to two or more fixed girders, the present invention can be applied as described above. A similar effect can be obtained.

Further, the control system may be controlled by a microcomputer (1) The same effect can be obtained by using the detection result of the swing arm detection relay.Furthermore, in the above embodiment, the swing arm detection relay illusion The rotating arm 11~
Although the example provided in No. 13 has been described, the present invention is not limited thereto.

In order to simplify the configuration, the same effect can be achieved even if it is used only for the swing arm 11, for example.

〔Effect of the invention〕

As explained above, according to the present invention, the point girder can be accurately positioned with a simple configuration.
