Description

[Detailed Description of the Invention] The present invention provides a transport device with a route switching rail, and more specifically, as shown in FIG. 2 Ascending (normal) route 3
The present invention relates to a conveying device, etc., which is provided with a switching rail 4 which is arranged in parallel in this order and which moves laterally between a descending route 2 and a second ascending route 3 so as to be selectively connectable to both of these routes.

In such a conveyance device, the conveyance cart 5 that has descended down the descending route 2 is stopped on the switching rail 4, and the switching rail 4 is moved laterally and connected to the second ascending route 3. 4 can be transferred to the second ascending route 3, but when the switching rail 4 is in the position where it connects to the second ascending route 3, the carriage 5 on the descending route 2 can be transferred to the second ascending route 3. The conveyor cart 5 is connected to the switching rail connecting free end 2a.
There is a risk that the descending transport vehicle 5 may slip off or fall from the switching rail connection free end 2a if the electrical function that automatically stops before the switch malfunctions or if the inertial downward movement distance becomes large due to slipping, etc. There is.

The purpose of the present invention is to solve the above-mentioned problems, and one embodiment of the invention is shown in Figs. 2 and 3 below.
This will be explained based on the diagram.

Reference numeral 6 denotes a non-return stopper provided at the upper end of the switching rail 4 (first side) on the side of the ascending route 1, and is connected to a support plate 7 fixed to the side surface of the switching rail 4 via a hinge 8, and is connected upwardly. The arm 9 is rotatably supported, a roller 10 is pivotally supported at the tip of the arm 9, and a tension spring 11 biases the arm 9 into a protruding position.

12 is an axis of the hinge 8; 13 is a cushioning rubber fixed to one mounting plate of the hinge 8 so as to be located between the opposing mounting plates; 14
is the rail of the first ascending route, 15 is the rail of the descending route, 1
6 is the rail of the second ascending route, 17 is the rail of the first ascending route 1 -
This is a transport vehicle that goes up.

When the switching rail 4 is in the position where it connects to the descending route 2 as shown in the figure, the stopper 6 closes the roller 1 at the tip.
When the switching rail 4 is in the position where it connects to the second ascending route 3, the roller 10 at the tip protrudes into the descending route 2.

Therefore, when the switching rail 4 is in the position where it connects to the second ascending route 3, the descending conveyance carriage 5 descending on the descending route 2 can be stopped by the roller 10 of the stopper 6, and the shock at this time is also absorbed by the cushioning rubber. 13 can be buffered.

When the switching rail 4 is in the position connecting to the descending route 2, the ascending carriage 17 ascends the first ascending route 1.
is able to pass through this stopper 6 without being obstructed while rotating the arm 9 upwardly and laterally around the shaft 12 against the spring 11, and at this time the roller 10 moves upwardly toward the carriage 17.
Since the lifting carriage 17 rolls into contact with the side surface of the lifting carriage 17, the passage of the ascending carriage 17 is also carried out smoothly.

As shown in the above embodiments, the present invention has a simple structure in which a switching rail is provided with a non-return stopper that only accepts the descending (reverse) transport vehicle and allows the passage of the upward (forward) transport vehicle. However, there is an accident in which the transport vehicle moving on the descending (reverse) route slips off or falls from the free end of the switching rail connection without interfering with the movement of the transport vehicle traveling on the first upward (forward) route. can be prevented from occurring.

As another method for obtaining such an effect, a stopper that is biased to a protruding position by a spring and can move forward and backward is provided at the free end of the rail 15 of the descending path 2, and the switching rail 4
It has been considered that when the stopper moves laterally to the position where it connects to the rail 15, the switching rail switches the stopper to the retracted position that allows the carriage to descend.
Such a configuration requires an actuator that moves the stopper in and out through contact with the switching rail 4, a link mechanism that links the actuator and the stopper, or an operation unit that operates the actuator on the switching rail 4 side. This not only complicates the structure and significantly increases costs, but also causes poor maintenance of the pivot joints of these movable members, causing the stopper to fail even though the switching rail 4 has moved away from the descending path rail 15. There is also a possibility that the body will not switch smoothly to the protruding position.
It is necessary to perform sufficient maintenance and inspection to ensure that the stopper always operates smoothly and reliably.

On the other hand, according to the configuration of the present invention, instead of automatically switching the posture of the stopper that can move in and out using the switching rail 4, the switching rail 4 is placed on the switching rail 4 itself.
A reverse conveyance carriage receiving stopper is provided so as to protrude from the lower end of the descending route 2 when the vehicle moves sideways to the position where it connects to the second ascending route 3. Therefore, an actuator or an operating section that operates this stopper to move in and out is provided. Alternatively, there is no need for an interlocking mechanism, and the structure is extremely simple and can be implemented at low cost. The carrier is automatically positioned at the lower end of the descending route 2, and the carriage can be reliably prevented from falling from the descending route 2.

That is, although the structure is extremely simple and can be implemented at low cost, the intended purpose can always be achieved reliably.

Also, just by attaching the stopper to the existing switching rail,
Since the other rails and the like can be used as they are, the present invention can be easily and inexpensively applied to existing conveying equipment, and the above-mentioned effects can be obtained.

All of the above explanations have been made by taking as an example a conveyance device in which the conveyance vehicle moves in the vertical direction, but it can also be implemented in a conveyance device in which the conveyance vehicle moves in the horizontal direction. Even if the transport vehicle that should be stopped does not stop due to a malfunction or the like, it can be forcibly stopped using the non-return stopper, so the same effect as described above can be obtained.
