Description

[Detailed description of the invention] Industrial application field This invention transmits the rotation of a drive shaft disposed along a track as a propulsive force to the trolley using a transmission medium such as a friction disk mounted on the trolley. The present invention relates to a traverse device that employs a drive system that causes a bogie to travel.

BACKGROUND TECHNOLOGY As mentioned above, a bogie drive system (hereinafter referred to as A traverse device employing a friction transmission truck drive system (simply referred to as a friction transmission trolley drive system) is known, for example, from Japanese Patent Application Laid-Open No. 164562/1983, and is widely used for the following reasons.

In other words, it is easy to use the friction transmission trolley drive system.
Compared to the pinion drive method, the equipment cost is lower because the only drive transmission member placed along the track is the rotating shaft.Especially with the above-mentioned traverse device, the traverse bogie cannot be used at any other than the stop positions at both ends. The friction transmission trolley drive method is advantageous because there is no need to control the speed of
When using the fluid cylinder, there is a disadvantage that the traverse stroke cannot be freely designed due to the restriction of the length of the cylinder, whereas the friction transmission truck drive system is advantageous because it does not have this restriction.

Problems to be Solved by the Invention However, as mentioned above, there is only one disadvantage when configuring the traverse device using the friction transmission truck drive method, and that is that the stopping position of the truck provided at each stop position on the traverse track is It is complicated, and this fact is a factor that increases the equipment cost in no small part.

Means for Solving the Problems The inventors of the present invention have conducted various studies to resolve the above-mentioned inconveniences, and have found that the traverse bogie only needs to stop at any stop position (main track position) on its moving track. We discovered a feature that does not require the operation of stopping multiple bogies on the track at multiple positions at the same time as in a normal bogie operation system, and connected the stopping positions of the traverse bogies in the above-mentioned traverse device to a single drive source. This is how we arrived at this idea.

Example Examples will be described below based on the drawings.

As shown in FIG. 2, the traverse device 1 according to the present invention is installed at the end of two main track A and B laid in parallel, and is mounted on a goods loading trolley on main track A or B. 2 onto the traverse truck 3, the traverse truck 3 moves on a moving track 4, sends the loaded truck 2 to another main track B or A, and completes the traverse. In this embodiment, the method of moving the carts 2 on the main track A, B is also based on a friction transmission cart drive method.

The engaging piece 17 of the goods loading cart 2 transferred onto the traverse cart 3 is moved to the drive shaft 9 by the cam plate 24 located at the solid line position in FIG. When pushed in the direction, the friction disk 14 is placed directly above the drive shaft 9 to decelerate the truck 2, and the fixed stopper plate 2 on the lower surface of the truck 2 is moved.
8 (FIG. 4) is stopped at a fixed position by being engaged with the pivot stopper 27 which is pivoted to the engagement position. The trolley 2 is restarted by rotating the drive shaft 9 in the opposite direction and then performing a reverse operation to that described above.

The friction transmission mechanism on the lower surface of the traverse truck 3 may have the same structure as the friction transmission mechanism on the lower surface of the article loading truck 2 using a slidable friction disk, which is schematically illustrated and explained in FIG. Structural parts are indicated by the same numbers. Also, this traverse trolley 3
It may also be constructed using a friction disk that can freely rotate in a horizontal plane as disclosed in the above-mentioned Japanese Patent Application Laid-open No. 55-164562, or other mechanisms in which the friction disk rotates around a horizontal axis. You may use any of the following.

Next, the moving track 4 of the traverse bogie 3 will be explained. As mentioned above, the moving track 4 extends between the two main line tracks A and B, and the friction between the two rails 31 and the lower surface of the traverse bogie 3 Disk 14

Two stopping cam devices 36 and 37 are provided on the moving track 4 according to the positions of the main track A and B, and the stopping cam devices 36 and 37 are arranged as follows according to the present invention. It is structured as follows.

That is, the stopping cam devices 36 and 37 have substantially the same structure as the stopping cam device 18 on the traverse truck 3, and as shown in FIG. 39 on the base 33, and the other end is rotatably supported by other protruding pins 45, 46 on the base 33. A cam plate 4 provided so as to be freely movable in the direction of the drive shaft 32 between the solid line and the chain line shown in Figure 1.

A driving fluid cylinder 53 is provided only in one of the stopping cam devices 36, and the stopping cam devices 36, 37 rotate together with the respective rotating plates 43, 44 and rotating stoppers 51, 52. The pivot levers 54 and 55 are connected to each other by a connecting rod 56 so that they are interlocked.

That is, the fluid cylinder 53
The a end is connected to the pivot pin 57 of the pivot plate 43 and the link 38, and when the cylinder 53 is extended and in the state shown in solid line in FIG.
side, that is, the main track A side, is the cam plate 47 on the drive shaft 3
As well as moving forward in two directions, the cam device 37 for stopping
The cam plate 48 on the side, that is, on the main track B side, retreats,
In the state indicated by the chain line in FIG. 1 when the cylinder 53 is contracted, the respective operations are reversed.

Reference numerals 58 and 59 indicate L-shaped planar regulating plates that regulate the turning ends of the respective turning stoppers 51 and 52.

In addition, in the traverse device of this embodiment, the above-mentioned turning stopper 51 is provided on the lower surface of the traverse truck 3.
In addition to the fixed stopper plate 28 that engages with the fixed stopper plate 52, one fixed stopper plate 61 is vertically provided (the fifth
), swing stops 62 and 63 that can engage with the fixed stop plate 61 are provided on the moving track 4.

That is, as shown in FIG.
Swing stoppers 62 and 63 are provided which are L-shaped in side view and are swingable around pins 64 and 65 protruding from the upper stopping cam devices 36 and 37, respectively. The driving fluid cylinders 62 and 63 are also provided only on the stopping cam device 36 side. In other words, the above-mentioned stopping cam device 3
6 and 37, the rotation stoppers 62 and 6
3 also has pivot levers 67 and 68 protruding from the pivot levers 67 and 68 that pivot together around pins 64 and 65.
7 and 68 are connected to each other by a connecting rod 69, and a cylinder rod 66a is attached to the swing lever 67 on one side.
These swing stoppers 62 and 63 are designed to swing in the same direction as the fluid cylinder 66 expands and contracts.

Next, the operation of the traverse device 1 of the above embodiment will be explained.

That is, for example, in order to traverse the article loading cart 2 on the main track A to the main track B, first the fluid cylinder 66 is contracted and the swing stopper 6 is moved.
2 and 63 in the disengaged position (dashed line in FIG. 1), the fluid cylinder 53 is extended, and the cam plate 47 is moved forward in the direction of the drive shaft 32. In this state, when the drive shaft 32 is rotated in the appropriate direction and the traverse truck 3 is made to travel in the direction of the main track A, the traverse truck 3 is at the stop cam device 36 position, and the friction disk 14 on the lower surface of the traverse truck 3 is in the position of the stopping cam device 36. Engagement piece 17
The fixed stopper plate 28 is held directly above the drive shaft 32 and decelerated, and the fixed stopper plate 28 is stopped at an accurate fixed position by being stopped by the swing stopper 51 at the engagement position.

In this state, the locking position is only determined in one direction by the rotation stopper 51, so
Next, move the other swing stopper 62 to the engagement position (first
(solid line in the figure), and the swing stopper 62 is brought into contact with the fixed stopper plate 61 on the lower surface of the traverse truck 3 from the other direction, and the position of the traverse truck 3 is securely fixed by regulation from both directions along the rail 31. Make it something.

In this way, after the traverse truck 3 is stopped on the moving track 4 at an accurate position where it connects to the main line track A, the drive shaft 9 on the traverse truck 3 and the drive shaft 7 of the main line are rotated in the appropriate direction to move the goods loading truck 2 onto the traverse truck 3. Traverse trolley 3
The cam device 18 decelerates, stops, and restarts the truck 2 above.

To restart the traverse truck 3 loaded with the truck 2, first rotate the drive shaft 32 in the reverse direction, then bring the swing stopper 62 to the disengaged position, contract the cylinder 53, and press the cam plate 47. When the traverse truck 3 is moved backward, the friction disk 14
The traverse truck 3 assumes the position shown in FIG. 5, eccentric again with respect to the drive shaft 32, and the traverse truck 3 starts traveling in the direction of the main track B. At this time, the operation of starting the bogie 3 on the main track A with the cylinder 53 contracted is equivalent to moving the cam plate 48 on the main track B side forward in the direction of the drive shaft 32, that is, stopping the bogie 3. There is no need to perform another cylinder operation when the traverse truck 3 approaches the main track B side.

Similarly, when the swing stopper 62 on the main track A side is turned to the non-engaging position, the traverse cart 3 is accepted on the main track B side, so the swing stopper 62, 63 for fixing this position remains unchanged.
Also, no new cylinder operation is required, simplifying the operation.

As mentioned above, the operation of cylinders 53 and 66 for starting the bogie 3 on the main line track A side is equivalent to receiving and stopping the bogie 3 on the main line track B side, so it is not started from the main line track A side. The traverse truck 3 is automatically decelerated and stopped at the main track B position by the action of the cam plate 48 and the swing stopper 52 similar to those described above. Therefore, next
As before, if the swing stopper 63 is brought to the engaged position and the fixed stopper plate 61 on the lower surface of the traverse bogie 3 is restricted by the swing stopper 63, the traverse bogie 3 will be located at the correct position where it connects to the main track B. drive shafts 9 and 7.
By rotating the cam device 18 in the direction opposite to that at the time of carrying in and also operating the cam device 18 in the direction opposite to the direction at the time of carrying in, the article loading trolley 2 is sent out from the top of the traverse trolley 3 to the main track B.

In addition, in the above embodiment, the rotation stoppers 62, 63
By providing these swing stoppers 62, 6, the position of the traverse truck 3 can be fixed more accurately and reliably at each of the main track positions A and B.
3 may be omitted to configure the traverse device, or the stopping cam devices 36 and 37 may be provided at three or more locations on the moving track 4 to provide a traverse device that spans three or more main track.

Effects of the invention As is clear from the above explanation, the traverse device according to this invention uses a single drive source for the stopping device, which simplifies the structure of the entire traverse device and reduces equipment costs. Moreover, since it is a traverse device, in order to stop the traverse truck, it is only necessary to operate the stopping device at one location, and there is no problem caused by unifying the drive source.
