Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to equipment for transporting articles in buildings such as hospitals and office buildings, and in factories, and particularly relates to the structure of a joint between horizontal transport and vertical transport. .

[Background of the invention]

As shown in Fig. 3, the conventional conveyance equipment consists of a horizontal conveyance device that conveys to a station installed on each floor, and a vertical conveyance device that conveys up and down between each floor. Receive cargo from the road. A container 1 loaded with goods to be transported is suspended from a self-propelled vehicle 2, and the self-propelled vehicle 2 travels while being guided by a guide rail 4 having a mouth-shaped cross section and installed on the floor 3 of a building. A hoistway 6 that passes through each floor is installed on the extension line of the end of the guide rail 4, and a hoisting machine 7 is placed at the top of the hoistway 6. A guide rail 10 having the same cross-sectional shape as the guide rail 4 on the building side is arranged on the elevating object 9 on which the elevating object 9 is suspended so as to coincide with the extension line of the guide rail 4. That is,
The elevating body 9 is moved upward and downward by the hoisting machine 7, and the guide rail 10 is configured to stop on the extension line of the guide rail 4 provided on each floor, and the guide rail 10 can extend left and right, The self-propelled vehicle 2 is allowed to ride on the guide rail 10.

Next, a state in which the first self-propelled vehicle 2 gets on and off the guide rail 10 of the elevating body 9 will be explained.

As shown in FIG. 1, a drive row 21 that drives the self-propelled vehicle 2
2 is configured to press against the upper surface of the guide rail 4, and furthermore, a guide roller 13 that supports its own weight is in contact with the lower surface of the guide rail 4. Therefore, if there is a step between the guide rail 4 and the guide rail 1G in the upper and lower directions, the driving force of the drive row 212 will be insufficient, making it impossible to board the container, and impact will be applied to the container when boarding, causing the container to be transported. This level difference must be made as small as possible because it may have a negative impact on objects.

For this reason, in normal operation of the elevating body 90, the accuracy is limited to about ±10m with respect to the target Vpel, so in order to further reduce this, it is necessary to perform I/CHINOG operation.
The control is complicated and expensive, and the vertical conveying equipment is unsuitable for use as a conveying equipment.

Note that related devices of this type include, for example,
Utsukai Showa 52-44580. Utility Model Application Publication No. 58-92271 is mentioned. The former has a complicated structure, and the latter has no concrete structure, so neither of them can provide a concrete solution to the problems of the present conveyance equipment.

[Summary of the invention]

The gist of the present invention is that it is configured to perform vertical and downward positioning without a special drive source in conjunction with the extending movement of the guide rail of the elevating body.

[Embodiments of the invention]

Hereinafter, one embodiment will be described based on FIG. 1 and FIG. 2.

The guide rail 10 of the elevating body 9 has both ends rotatably inserted into vertically elongated holes 24 provided in the support body 15 using pins 14.
It is attached so that it can be slid upwardly and downwardly, and the lower surfaces of both ends are placed on vibration isolators 16 provided on the support body 15, and engaging bodies such as cam followers are attached to both ends that engage with the guide rails 4 on the building side. 17 are made to protrude from both sides of both ends of the f-id V-rule lO. The support body 15 has a roller 18 on its upper part, and a drive device 2 such as an electric cylinder along a guide frame 19.
0, it is configured to be movable in the direction of the arrow in FIG.

Further, on both side surfaces of the end of the guide rail 4 on the building side, positioning members 22 having slopes 21 are provided at positions where they engage with the engaging bodies 17. Furthermore, the stopping position of the elevating body is set at the stopping position of the pair 10 on the guide rail 4. When the elevating body 9 stops, the drive device 20 operates, and the guide rail 10 moves to the left in FIG. 2 along with the support via the bin 14 until its lower part contacts the lower part of the guide rail 4. However, at this time, the engaging body 17 engages with the slope 21, the left end of the guide rail 10 rotates upward using the pin 14 as a fulcrum, and finally the engaging body 17 engages with the horizontal surface 23, The state shown by the two-dot chain line in FIG. 2 is reached, and the level difference between the guide rails in the upper and lower directions is almost zero. At this time, since the elevating body is provided with an upward and downward elongated hole 24 as a retaining portion for the pin 14, the bottle 14 can be displaced upward as shown by the two-dot chain line in FIG. Further, on the opposite side, the bin 14 engages with the lower part of the elongated hole 24 due to the weight of the rail 10, and serves as a rotational fulcrum.

In this way, after the guide rail 10 engages with the guide rail 4, the self-propelled vehicle 2 is guided by the guide rail 1o, gets on the elevating body 9, drives the drive device 20, and moves the guide rail 0 as shown in FIG. After moving it to the position indicated by the solid line, lift body 9
5 or more, in which the lever moves up and down, is the case when the lever is engaged on the left side in FIG. 1, but when it is engaged on the right side, the operation is the same except that the fulcrum and the rotation side are reversed.

With such a configuration, even if a stopping error of the elevating body 9 occurs,
The height difference in the vertical direction between the guide rail 4 and the guide rail 10 can be made almost O, and the self-propelled vehicle 2 smoothly gets onto the elevating body 9 at the V-ru joint part without any impact when hanging down. be able to. Further, normal control is sufficient for stopping the elevating body, and there is no need to perform special inching control, and the control device can be simplified and inexpensive.

In addition, since the vibration isolator 16 is provided, the guide V-ru 1
It is possible to reduce the impact when 0 returns from the engaged state to the original position. Furthermore, since the engaging body 17 is constituted by a rotating body such as the cam 7 lower, there is less resistance when riding on the slope 21, and the output of the drive device can be reduced.

The case where the self-propelled vehicle 2 gets onto the elevating body 9 from the building side has been described above, but the same effect can be obtained when the self-propelled vehicle 2 gets off from the elevating body 9 toward the building side.

〔Effect of the invention〕

According to the present invention, no special drive device is required to perform V-ru positioning in the vertical direction, and vertical positioning is performed mechanically in conjunction with the guide rail extension operation of the elevating body. Therefore, it is possible to provide a conveying facility that is easy to control, has a simple structure, and is inexpensive.
