Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a guide track crossing crossover line for changing the traveling route of a guide track vehicle traveling along a guide rail provided on a track.

Conventionally, as shown in FIG.
A vehicle has been developed in which a vehicle is guided along the guide rail 2 and travels on the running path 1.

In such a guide track, when changing the running route from straight tracks 3 and 4 to curved tracks 5 and 6 as shown in FIG. 2, the movable straight line between fixed guide tracks 7 and 8 A vehicle enters in the direction of the arrow by lowering the guide rail 9 (indicated by a broken line) to the same height as the running road surface, while raising the movable curved guide rail 11 located between the fixed guide rails 7 and 10 to open the curve. is guided by a movable curved guide rail 11 toward a fixed guide rail 10.

On a double-track guide track as shown in Figure 3, up line 1
For the crossing from the down line 13 to the down line 13, there is a crossover line 15 using the above-mentioned left branch switch 14, as shown in FIG. For this purpose, a crossover wire 17 using a right branch switch 16 is required as shown in FIG.
7 were installed in a V-shape as shown in Figure 4A.

However, when the two crossover wires 15 and 17 are installed side by side in this way, a length that is at least twice as long as the installation length of the switch for one crossover is required, and there is a problem in that the installation location is severely restricted.

As a solution to this difficulty, an installation method can be considered in which both crossover wires 15 and 17 are placed one on top of the other and the fixed rail section in the center is rotated, as shown in Figure 4B, but as a practical matter, the connection between the track and the vehicle is conceivable. Problems with signal information transmission between the two, as well as problems with engagement and fixation between the rotating guide rail and the up-and-down guide rail, prevented this from being realized.

The present invention has been made to solve the above-mentioned problems of the conventional art.The purpose of the present invention is to provide two crossovers, a left crossover line and a right crossover line, with the track length of a crossover line segment in one direction. To provide a guide track crossing crossover in which a guide track is erected at the center of a track where a line is installed and a running path is provided on both sides of the guide track.

Hereinafter, one embodiment of the guide track crossing crossover line of the present invention will be described with reference to the drawings.

In FIG. 5, reference numeral 18 denotes a fixed guide rail of the up line, between which movable linear guide rails 19 and 20 are arranged.

A fixed guide rail 21 is also installed between these movable linear guide rails 19,20.

Similarly, two movable linear guide rails 23, 24 and a fixed guide rail 25 are arranged between the fixed guide rails 22 of the down line.

A rotary guide track device 26 is installed between the fixed guide rails 21 and 25.

Between this rotating guide track device 26 and each of the fixed guide rails 18 and 22, there are movable curved guide rails 28, 29, 3, respectively.
0 and 31 are arranged.

The rotary guide track device 26 is rotated so that the guide rail 27 installed thereon is connected to the movable curved guide rail 28 and 2.
9, it is possible to open the left branch crossover, and on the other hand, the guide rail 27 can be connected to the movable curved guide rail 3.
By matching 0 and 31, the right branch crossover can be opened.

Each of the movable straight guide rails 19, 20, 23 and 24 and each of the movable curved guide rails 28, 29, 30 and 31 can be lowered to the same height as the running road surface, and the left branch crossover shown in FIG. At the time of opening, movable straight guide rails 19 and 24 and movable curved guide rails 30 and 3 are installed as shown by broken lines, respectively.
1 is lowered, and conversely, in order to open the right branch crossover line, the movable straight guide rails 20 and 23 and the movable curved guide rails 28 and 29 are lowered.

Fig. 6 shows a vertical operating device for the movable curved guide rail 28, and Fig. 7 shows a locking function of the vertical operating device.
The movable curved guide rail 28 is driven up and down via the movable curved guide rail 28.

This crankshaft 33 extends along the movable curved guide rail 28.
It is rotatably supported by bearing stands 34 provided at certain locations, and is synchronously rotated from a single power source (not shown) via a drive shaft.

A roller 35 is attached to the tip of the other arm of the crankshaft 33, and when the movable curved guide rail 28 is raised, the point of connection 33a between the crankshaft 33 and the connecting rod 32 crosses the dead center. It comes into contact with a stopper 36.

At this time, the movable curved guide rail 28 itself also comes into contact with an upper limit stopper (not shown) and is in tension with the bearing stand 34, so that a load indicated by arrow P is generated on the connecting rod 32.

As a result, a rotational force indicated by arrow T acts on the crankshaft 33, and a force acts in a direction that always presses down the stopper 36, so that the movable curved guide rail 28 is stably held in the raised position.

This stability maintenance is also achieved in the lowered position using the same principle.

The explanation has been given above using the movable curved guide rail 28 as an example, but
The same applies to the vertical operating devices of the other movable curved guide rails 29, 30 and 31 and the movable linear guide rails 19, 20, 23 and 24.

In addition, a limit switch 3 is installed in the vertical operating device to confirm the completion of the operation and to detect the position of the movable curved guide rail 28.
7 (see FIG. 6), the limit switch detection arm 37a is actuated by limit switch strikers 33b and 33c provided on the crankshaft 33.

Next, the rotation mechanism of the rotational guide track device 26 will be described in detail with reference to FIGS. 8 and 9. 3. A guide rail 27 erected in the center and a running path integrally formed on both sides of the guide rail 27 38 has its central shaft 39 supported by a bearing portion 40, and its outer peripheral portion supported by a sliding bearing 41 so that it can rotate.

Reference numeral 42 denotes a torsion bar, whose lower end is fixed to the lower part of the traveling path 38 via a torsion bar receiver 43, and whose upper end is rotatably supported by the torsion bar receiver 43.

A torsion bar arm 44 is attached to the upper end of the torsion bar 42 so as to face outward.

Therefore, the torsion bar arm 44 is elastically coupled to the rotation guide track in the torque direction via the torsion bar 42.

This torsion bar arm 44 is U-shaped as shown in FIG. 10, and a driving roller 45 is fitted inside it.

The driving roller 45 is attached to the tip of the driving arm 46 and is rotated by a power device 47 with a rotation radius R, and as shown in FIG. side stopper 26a
The rotation guide track device 26 rotates by θ until it hits the stopper 56a on the a support side.

As described above, when the torsion bar arm 44 moves from the chain line position to the solid line position, the torsion bar 42 is twisted by the torsion angle α, so that a force P' acts on the driving roller 45.

As a result, a rotational force T' is generated in the drive arm 46, and the force acts in a direction that constantly presses the rear end of the drive arm 46 against the stopper 47a, so that the drive roller 45 is rotationally guided at a position beyond the dead center. It plays the role of stably holding the orbit device 26.

This effect is based on the same principle as the vertical operating device explained in FIG.

Further, in FIG. 9, 48 is a limit switch,
Striker 46 for limit switch provided on drive arm 46
a hits the detection arm 48a of the limit switch 48 to confirm completion of the rotational movement of the rotation guide track device 26.

Reference numeral 49 is a jack for lifting the rotation guide track device 26 and inspecting the bearings of various parts.

FIG. 11 shows the state of engagement between the guide rail 27 of the rotation guide track and the movable curved guide rail 28. The movable curved guide rail 28 has an upwardly facing trapezoidal sieve portion 28a; is a groove 27a that can fit into this trapezoidal sieve part 28a.
is engraved.

Therefore, in the engaged state, even if a lateral load is applied by the guide wheels of the vehicle, the slope portion of the trapezoidal sieve portion 28a and the groove side surface portion of the groove 27a come into contact with each other, resulting in a step formed on the side surfaces of both guide rails 27 and 28. can be kept to a minimum, and each guide rail 2
The lateral load received by 7.28 is distributed between the two, preventing it from being concentrated on one side.

The above-mentioned engagement is similarly performed between other fixed guide rails and movable guide rails.

A running path is laid on both sides of each of the above-mentioned rails, and a signal transmission line holding board 50 made of, for example, reinforced resin is provided inside the running path, which also serves as the running path.

This signal transmission line holding board 50 includes electric wires 5 for transmitting signal information.
1 is installed (see Figures 6 and 9).

This electric wire 51 for transmitting signal information is connected to the rotation guide track device 26.
is also provided, and transmits signal information for the left branch crossover line and signal information for the right branch crossover line according to the switching state.

A signal information transmission wire 51 is connected to one end of a matching box 53, and a flexible signal transmission wire 54 is connected to the other end of the matching box 53 to transmit electrical signals.

The flexible signal transmission electric wire 54 is supported by a cleat 55 on the rotation guide track device 26 side and a cleat 57 on the support stand 56 side so as not to interfere with the rotation of the rotation guide track device 26. It has a structure that ensures reliable signal transmission even when it rotates.

Since the guide rail crossing crossover line of this embodiment is configured as described above, each guide rail is operated in the state shown in the table below according to the leftward crossing and rightward crossing.

That is, when each guide rail is in the state shown in FIG. 5, a vehicle approaching from the direction of the arrow is aligned with the movable curved guide rail 28 in the raised position from the fixed guide rail 18 in a stopped state. It crosses leftward to the fixed guide rail 22 via the rotating guide rail 27 in the raised position and the movable curved guide rail 29 in the raised position.

In this case, the movable straight guide rail 19 and the movable curved guide rail 3
1 is lowered to a position flush with the road surface so as not to interfere with the running of the right-hand wheels of the vehicle, and similarly, the movable curved guide rail 30 and the movable straight-line guide rail 24 also prevent the running of the left-hand wheels of the vehicle. It is in a lowered position so that it does not get in the way.

When switching from left-handed crossing to left-handed crossing as described above, as shown in the middle row of the above table, first lower the movable straight guide rail 20.23 and the movable curved guide rail 28.29,
When these rails descend by C1, the aforementioned engagement with the rotation guide rail 27 is released, so the rotation guide track device 26 subsequently rotates by a predetermined angle θ, and the movable curved guide rail 3
It stops at a position consistent with 0°31.

At the same time as the lowering of each of the above-mentioned rails ends, the movable linear guide rail 19.24 starts to rise, and at the same time as the rotation of the rotary guide track 26 ends, the movable curved guide rail 31.30 starts to rise.

In this way, the crossover line to the right is opened. When switching to leftward crossing again, the same operation as described above is performed according to the program at the bottom of the table.

It goes without saying that confirmation of completion of the lowering and rotation is performed using the aforementioned limit switch or the like.

In addition, in this embodiment, movable linear guide rails 19, 20 and 2
Since the short fixed guide rails 21 and 25 are installed between 3.24 and 24, the ends of each movable guide rail can be firmly engaged and connected as described above.

In the present invention, a guide rail is erected at the center of the track, and a rotating guide track is arranged at the center of the intersection of crossover wires that intersect with each other as described above on a track with running paths on both sides. Since it is made to be vertically displaced, both the left and right crossover wires can be installed with the length of one crossover, which has the advantage of extremely reducing restrictions on the installation location.

Furthermore, according to the present invention, the movable guide rail of each point device and the rotary guide rail end are reliably connected to each other by an extremely simple operation, and are also strong, allowing large vehicles to pass through with a small guide rail cross section. .

Furthermore, since the rotational movement part of the rotation guide track is composed of a torsion bar and a drive device, it can be locked in a space limited to the limited plane of the crossover intersection and the same depth as an upper and lower type switch. It is possible to provide a rotation guide track that can perform reliable horizontal reciprocating rotation including functions.
