Description

[Detailed description of the invention] The present invention relates to a device that automatically stops a vehicle running on a rail at a predetermined position. In a transportation system that transfers items to a guided trolley,
The present invention proposes a device that can automatically stop a vehicle in the vicinity of the terminal when the bogie is absent, thereby preventing it from falling off the rail.

A golf equipment transportation system at a golf course will be explained below as an example.

As shown in Figure 1, this system consists of a transport vehicle (hereinafter referred to as a cart) 2 that straddles a single rail 1 laid along a course, and a motor is powered by a battery mounted on the cart 2. Wheel 21 rotated and connected to this
The cart 2 is driven on a single rail 1 by driving the cart 2.

The cart 20 can run and stop using a control lever provided on the car body or a remote controller (both not shown) carried by the player, and can also be automatically stopped at an appropriate position depending on course conditions. It has a mechanical structure.

Cart 2 is a device for performing such automatic stop.
The microswitch 20 provided in the microswitch 2
0 (locate it in its passing area and move the single rail 1
A switch dog 10 is provided, and the opening and closing operations of the microswitch 20 control the start and stop of the motor.

That is, FIG. 2 shows the main electrical circuit of the cart 2. As shown in FIG.

The positive terminal of the battery 22, whose negative terminal is body grounded, is connected to a normally open switch 23 (opens only during each operation when the operating lever is in the stop position or when a stop command is issued using the remote controller). 23 is used to turn on and off the positive side line, and between the positive side line and the body ground is a normally open V) switch (when the operation lever is set to the starting position, or when the remote control is used to turn off the stop). When commanded, it closes only during each operation) 24, electromagnetic relay 2
A series circuit consisting of the excitation coil 25C of No. 5 and the normally closed contact of the microswitch 20, and a series circuit of the normally open contact 25a2 of the electromagnetic relay 25 and the motor 26 for driving the wheels 21 are connected in parallel, and the switch A normally open contact 25a□ of the electromagnetic relay 25 is connected in parallel to the electromagnetic relay 24 for self-holding.

When the excitation coil 25C is energized by closing the switch 24, the contacts 25a□ and 25az are closed, the electromagnetic relay 25 is self-held, and the motor 26 is energized.

As a result, even after the switch 24 is opened, the motor 26 continues to rotate and the cart 2 continues to travel.

When the switch 23 is opened by operating a control lever or the like, or when the touch rod 20s of the microswitch 20 passes the mounting position of the switch dog 10, the switch dog 1
When the normally closed contact is opened by being pressed to 0, the self-holding of the electromagnetic relay 25 is released, thereby cutting off the power supply to the motor 26 and stopping the cart 2.

Now, in the latter case, when the microswitch 20 passes the mounting position of the switch dog 10, its normally closed contact 25a is closed again, so by closing the switch 24, the cart 2 resumes running.

As shown in FIG. 3, the single rail 1 is sometimes laid across a managed road 3.

In such a case, in order to enable the management mechanism to run on the managed road, one end of the 10-crossing section of single rails should be pivoted,
In addition, as a structure in which the other end can be engaged and detached, the other end of the crossing portion can be detached as necessary, and the crossing portion can be rotated around the one end as shown by the two-dot chain line in Fig. 3 and retracted. This is so that it can be done.

Therefore, a switch dog is installed at the end of the single rail 1 just before the intersection and the switch is temporarily stopped there to prevent accidents such as falling off the end of the single rail 1 or colliding with the part that has been rotated and retreated. This is to prevent it.

In addition, in the case of a slope with a slope exceeding the climbing ability of this cart, as shown in Figure 4, between the single rail 1a on the low ground and the single rail 1b on the high ground, which are laid in approximately parallel directions, these single rails should be installed. Chain conveyor 30 in the direction perpendicular to the rail (toward direction)
A single rail 3 is provided, and is moved up and down by the conveyor 30.
The cart 2 is mounted on a trolley 31 with 1a.

The trolley 31 is waiting for the arrival of the cart 2 with its single rail 31a aligned with the terminal end of the single rail 1a on the low ground.When the cart 2 is loaded on the trolley 31, the chain conveyor 30 is driven to move the high ground. It continues to rise toward the starting terminal of the single track 1b.

However, in order to prevent the cart 2 from falling off the terminal end of the single rail 1a when the trolley 31 is not in the standby position, a switch dog 10 is provided in front of the terminal terminal to temporarily stop the cart. I have to.

However, since the normally closed contact of the microswitch 20 returns to the closed state after passing through the mounting position of the switch dog 10, there is a problem that if the remote controller is operated carelessly, the cart may fall off the single track on which it started traveling. there were.

The present invention was developed in view of the above circumstances, and is designed to prevent the above-mentioned falling off at the single-rail terminal and ensure that the bogie 3
The purpose of the present invention is to provide an automatic stop device that can be used to transfer cargoes to other facilities.

The present invention will be described in detail below with reference to drawings showing an embodiment of the connection between the chain conveyor 301 and the lift 32 made up of the cart 31 and the like.

The automatic stop device according to the present invention (hereinafter referred to as the device of the present invention) has the same structure on the cart 2 side as the conventional one, and is modified only on the single rail side.

That is, FIG. 5 is an elevational view showing the configuration of the terminal portion of the single rail 1 facing the lower end of the lift 32, FIG. 6 is a partially sectional plan view, and FIG. 1 is taken along the line ■-■ in FIG. FIG.

This single rail 1 has a main rail 11 on which drive wheels 21 are rolled in contact with its upper surface, and an upper support wheel 27 pivoted on a vertical axis is rolled on the left and right sides to prevent it from falling sideways. , a main rail 1 directly below the main rail 11 at an appropriate distance apart.
1, and an auxiliary rail 12 that connects the support ring 28 attached below the support ring 27 to the left and right side surfaces, and both are located at positions separated by an appropriate length in the installation direction of the single rail 1. It is supported on the ground by pillars 13 provided at each location.

A vertical hole 12a is formed in the auxiliary rail 12 at a suitable location near the end of the single rail 1, and a rod 41 is rotatably attached to the hole 12a and an auxiliary fitting 40 fixed around the hole 12a.
A rectangular arm 42a that constitutes an actuating member 42 that is to be operated as a switch dog that actuates the microswitch 20 is provided at the upper end of the rod 41.
It is fixed.

In this way, a short rod 43 is attached to the auxiliary rail 12 so as to protrude only above the auxiliary rail 12 at a position several hundred meters away from the position where the rod 41 is provided in the direction of arrival of the cart.
The top of the rod 43 is oval in shape, and a rectangular arm 42b is fitted therein.

The arms 42a and 42b both have their tips located on one side of the single rail 1.
Between the tips of 2b is an operating rod 4 parallel to the single rail 1.
It is pivoted on 2c.

This operating rod 42c has a shape with a cylindrical portion at the end,
The actuating rod 42c and the arms 42a, 42b constitute an actuating member 42.

As shown in FIG. 6, the operating rod 42b is located off to one side from the single rail 1 in plan view, but a protrusion 42d is provided on the surface on the single rail 1 side halfway there; A tension spring 44 is tensioned between the support 13 located closer to the rod 43 than the rod 42d and the protrusion 42d, and the tension spring 44
c is urged toward the rod 43 side.

Then, an appropriate stopper (not shown) is provided on the actuating member 42 or the auxiliary fitting 40, etc., so that the actuating rod 42c can be moved toward the rod 43 by the tension spring 44, or the arm 42a,
The counterclockwise rotation of 42b in FIG. 6 results in the state shown by the solid line in FIG. 6, that is, the state or operation in which the arms 42a and 42b form a rectangle with the short sides and the operating rod 42c of the single track 19 as the long side. The limit is such that the rod 42c is at the farthest position from the single rail 1.

Note that it is free to move or rotate in the opposite direction against the tension spring 44.

- The lower end of the rod 41 has a rectangular bar-shaped retraction drive arm 4.
5 is fixed substantially horizontally with its tip portion protruding further than the end of the single rail 1.

Therefore, the dimensions such as the length of the arms 42a and 42b mentioned above are as follows.
As shown by the solid line in FIG. 6, when the retraction drive arm 45 is in a state parallel to the single rail 1 without any external force being applied to it, the outer edge of the operating rod 42 is in the passage area of the touch rod 20s of the microswitch 20, and the microswitch 20 If the touch rod 20s can be rotated by an amount sufficient to operate the arm 45, and if an external force is applied to the retraction drive arm 45 to rotate it by a predetermined amount clockwise in FIG. 6, the two-dot chain line in FIG. As shown, the outer edge of the actuating rod 42 is set so that it does not retreat from the passage area of the touch rod 20s and actuate the microswitch 20.

Further, the tip of the retraction drive arm 45 faces the passage area of the truck 31, and the amount of rotation thereof when the truck 31 stops at the lowest end of the chain conveyor 30 is the same as that of the operating rod 42c.
The length is determined so that it is sufficient to retreat from the passage area of the touch rod 20s.

Further, the length of the operating rod 42c is set to be slightly longer than the braking distance of the cart 2 (the distance from the position where the microswitch 20 is activated until the cart stops when a braking mechanism (not shown) operates).

The present device configured as described above operates as follows.

That is, as shown in FIG.
evacuation drive arm 4 when it is in a state where it is possible to transfer
5 in the clockwise direction by a predetermined amount to position the operating rod 42c in the non-operating area of the microswitch 20 (in other words, out of the passing area of the touch rod 20). The cart 2 that has arrived at the connection point with the lift 32 moves to the trolley 31 without stopping at the terminal of the single rail 1, and moves to the trolley 31 using a separately provided stopping means (for example, the single rail 31 provided on the trolley 31).
The cart is stopped at the switch dog 31b) located at point a.

On the other hand, as shown in FIG.
is not located at the child terminal of the chain conveyor 30, the operating rod 42c is located in the passage area of the touch rod 20s due to the force of the tension spring 440, so when the cart 2 arrives at the part where the operating member 42 is provided, the micro switch 20 is activated and the cart stops.

Therefore, under this condition, the touch rod 20 of the micro switch 20
s is rotated by the operating rod 42c and the micro switch 20
is activated, and its normally closed contact 20b remains open, so even if the switch 24 is closed by carelessly operating the remote controller, the excitation coil 25C is energized, and the motor 26 is therefore energized again. The cart is not energized and the cart starts running and does not fall off the single track terminal.

When the trolley 31 returns to the child terminal of the chain conveyor, the operating rod 42c retreats to the non-operating area of the microswitch 20, which closes the contact 20b of the microswitch 20, so that the switch 24 is not subsequently closed. This effectively drives the motor 26, and the cart 2
is transferred to the trolley 31.

As described above, the automatic stop device for a rail vehicle according to the present invention is supported so that the switch member can move in and out of the passage area, and
A switch actuating member extending parallel to the rail installation direction, and the actuating member being positioned in the passage area of the switch member (
a spring connected to the actuating member; and a retraction drive arm extending from the end of the rail into the travel area of the truck and connected to the actuating member so as to be driven by the truck to retract the actuating member from the passage area of the switch member. Therefore, in situations where it is possible to transfer to a trolley and there is no need to stop, unnecessary stops will not be made, and in situations where the trolley is not waiting and it is necessary to stop temporarily, it will not be necessary. Not only does it ensure that the vehicle stops, but it will continue to stop even if a travel command is given until there is no problem in restarting the vehicle, so careless operations can cause carts and other vehicles to fall off the tracks. This prevents damage to vehicles, rail equipment, and other facilities.

Also, stopping by the conventional switch dog 10 can be performed without any problem.

In the above embodiment, the evacuation drive arm 45 is configured to rotate in one direction, and the arms 42a and 42b are configured to rotate in one direction. The actuating rod 42c is moved to the rod 41 side on the other side of the child 42d, and the arms 42a, 42b are rotated clockwise (a tension spring is provided to bias the arm 42c, and the tension spring 44 is balanced with the tension spring 44). A configuration may be adopted in which the state shown by the solid line in FIG. 6 is obtained, and the retraction drive arm 45 can be rotated in both directions.

Furthermore, it goes without saying that the present invention can be used not only in the above-mentioned embodiments but also in other types of rail vehicles in general.
