Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a transport facility for storing items such as meals in a wagon and automatically transporting them to each floor in a hospital or the like.
In particular, the stopping position of a self-propelled trolley carrying a wagon can be automatically and reliably determined.

[Background of the invention]

For example, as shown in Japanese Utility Model Application Publication No. 58-137686, an elevator hoistway is formed by penetrating multiple floors, and the elevator shaft runs between the elevator lifting body and the cargo handling section formed at each floor. Transport facilities equipped with self-propelled carts for transport are known.

This method requires that the wagon be accurately placed within the stop zone of the self-propelled trolley at the cargo handling section on each floor.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a safe and reliable automatic transport facility in which the stop position of a self-propelled cart is automatically determined.

[Summary of the invention]

In order to achieve the above object, the present invention detects the position of the wagon and determines the stopping position of the self-propelled trolley, and moves the wagon to a predetermined position of the self-propelled trolley at the station on each floor. Because it can be loaded accurately, there is no unbalanced load and it can be transported safely. Since it is not necessary to set the position of the loaded wagon so accurately, it is possible to improve man-machine efficiency and to obtain reliable conveyance equipment.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 8.

This transportation equipment includes a wagon 2 for storing objects 1 such as meal serving trays, an elevator for transporting items up and down between floors,
The wagon 2 is transported in the horizontal direction between a vertical transport device such as a dumbwaiter, a wagon station provided near the entrance/exit of each floor of the hoistway of the vertical transport device, and the elevator 7 of the vertical transport device and between the stations. Figure 1 shows the overall structure, Figure 2 shows a wagon car,
Figures 3 and 4 show how the wagon and self-propelled vehicle are mounted.

At the bottom of a wagon 2 that stores objects 1 such as serving trays, there are wheels 3 that can be moved by hand. Furthermore, a gap G is provided below the wagon 2 into which the self-propelled vehicle 4 can enter. The self-propelled vehicle 4 has wheels 5 that are directly connected to a drive motor (not shown) so that it can run horizontally, and a lift device 6 that can lift the wagon 2 by a certain distance G+.
Eri is configured. The vertical stroke dimension G2 of the lift device 6 is set to 02>Gl so that the lift device 6 can easily pass through the lower part of the wagon 2 when it is lowered. The vertical transport device that moves vertically between each floor is a wagon 2.
It also includes an elevating body 7 on which the self-propelled vehicle 4 is mounted, a wire rope 8 for suspending the elevating body 7, and a hoist 9 that drives in the vertical direction. On the other hand, the structure of each floor station is, as shown in FIGS. 5 and 6, a guide device 10a having a detector (not shown) for detecting the position of the wagon 2.

10b is provided, and the wagon 2 is arranged at a predetermined position. The detection device for commanding the stop position of the self-propelled vehicle 4 at the station is provided with a detection sensor 11 such as a magnetic sensor on the side of the self-propelled vehicle 4, and at a position corresponding to the detection sensor 11, as shown in FIGS. , a detection piece 12 such as a magnet is provided at the bottom of the wagon 2, and the self-propelled vehicle 4 that has entered the bottom of the wagon 2 detects the position of the detection piece 12 using a detection sensor 111t, and detects the position opposite the wagon 2. It is configured to be detected.

The configuration of one embodiment of the conveyance equipment according to the present invention has been described above, and its operation will be explained.

When transporting the wagon 2 from the IF to the 3rd floor, first set the wagon 2 at a predetermined position 101 of the IF station, press the destination button on the operation panel 13 provided on the wall to register the destination, and the elevating body 7 will move to the IF station. arrive at. The self-propelled vehicle 4 travels from the elevating body 7 toward the IF station position 101, and enters the lower part of the wagon vehicle 2 placed at that position. The wagon 2 is detected by the detection sensor 11 attached to the side of the self-propelled vehicle 4.
The detection piece 12 attached to the lower surface of the self-propelled vehicle 4 is detected and the self-propelled vehicle 4 stops. That is, by recognizing the position of the wagon 2, the self-propelled vehicle 4 will stop at that position, and even if the set position of the wagon 2 shifts from A to B by B as shown in FIG. The stopping position of the self-propelled vehicle 4 relative to the wagon 2 can be set to a position where there is no problem in lifting the wagon 2 gold. Next, the self-propelled vehicle 4 lifts the wagon 2 with the lift device 6, runs toward the elevating body 7, and gets into the elevating body 7. The elevating body 7 rises toward the 3rd floor,
It stops at the predetermined position F. The self-propelled vehicle 4 runs toward the 3rd floor station with the wagon on board, and for example, moves to position 30.
1, the lift device 6 is lowered, and the wagon 2 is placed on the floor. The self-propelled vehicle 4 again runs toward the elevating body 7,
It stops at a predetermined position within the elevating body 7 and waits until the next conveyance. Conversely, when transporting from the 3F to the IF, the above-described transport order may be reversed.

An example of the transport procedure has been described above, and by performing such a device configuration and operation, it becomes possible to automatically transport the wagon 2 safely and reliably to any desired station. Also, for example, when transporting meals within a hospital, the food will be transported from the IF kitchen to the patient rooms on the 2nd to 4th floors. Then, after a certain period of time, the transport pattern becomes such that the wagon is collected from the station on each floor of the 2nd to 4th floor to the key station of ``II''.In such a case, as in the present invention, the position of the wagon is recognized and the self-propelled vehicle is stopped. By doing so, even if the set position of the wagon at each floor station shifts, there is no need to manually reset the wagon, and more reliable automation becomes possible. By simply setting the vehicle in a certain zone, there is no need to accompany the vehicle until the collection is completed at the 1st floor station, and it is also possible to centrally manage delivery and collection of wagons at the IF key station.

〔Effect of the invention〕

According to the present invention, it is not necessary to set the wagons at each station very strictly, and the self-propelled vehicle can mount the wagons in accurate positions, so that the transportation can be carried out safely and reliably. In addition, it becomes possible to minimize human intervention during transportation, making automation easier, and rationalizing logistics within buildings such as hospitals and saving labor.
