Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for automatically transporting an automatically traveling trolley using an elevator.

The use of self-driving trolleys has been proposed to automatically transport cargo. In hospitals, etc., a serving table is placed on an automatically traveling trolley, which is then placed on the car of a cargo elevator and transported to each floor. In other words, if you operate the button on the self-driving trolley in the serving room and indicate the destination floor,
The self-driving trolley automatically travels towards the elevator landing. When the elevator car arrives at the landing, the cart gets into the car, the car automatically travels to the designated floor, and the cart gets off the car and automatically travels to a predetermined position.

However, in order to do so, it is necessary to specify the destination floor each time the trolley is sent out from the serving room, which is troublesome. Also, the button that indicates the destination floor is dirty.
You win by being unclean.

This invention improves the above-mentioned problems by simply generating a single output from the departure command device installed at the departure point, and by sequentially issuing pre-memorized preceding floor command signals, it is easy to reach the destination floor. The purpose of the present invention is to provide an automatic transport device for an automatic traveling trolley that can be given instructions.

Hereinafter, an embodiment in which the present invention is applied to hospital catering will be described with reference to FIGS. 1 and 2.

In Figure 1, 1A is the floor of the departure point such as a serving room on the first floor, 1B is the floor of the elevator landing located on the same floor as the departure point 1A, and 2 is the inside of the departure point floor 1A and the landing floor 1B. Induction wires that are buried inside and connect the two places and create a magnetic field through low frequency current, 3A, 3B
4A and 4B are serving tables loaded on trolleys 3A and 3B, respectively, 5 is a departure command board installed at the departure point, and 6 is a departure command board. 5, the trolley 3A,
3B is a display that displays the destination floor, 7 is a departure command device that is installed on the floor 1A of the departure point near the departure command board 5 and is operated by foot, and 8 is a departure command device on the floor 1 of the landing area.
This is the elevator car that landed at B.

In Fig. 2, 10 is a monostable element connected to the departure command button 7, and 10a is its output, which controls the car 8 to 1.
A signal 11 for calling to the floor is provided on the departure control panel 5 and connected to the monostable element 10, and is connected to terminals Q ₁ , Q ₂ to _{Q 9}
Any one of them is always "H", and each time the terminal T becomes "H", the "H" position moves one by one to the right in the figure.A command generation system consisting of a circular register. device, 112 to 119 are terminals respectively
The outputs of Q ₂ to _{Q 9} are the serving command signals for the 2nd to 9th floors, respectively. 12 is "H" when car 8 is on the 1st floor.
13 is an in-car detection signal (detector is omitted) that becomes "H" when bogies 3A and 3B enter car 8, and 14 to 22 are provided in the elevator control panel (not shown). AND gates 15a to 22a are AND gates 15 and 15a to 22a, respectively.
-22 outputs are car call signals requesting that the car 8 travel to the second to ninth floors, respectively.

Next, the operation of this embodiment will be explained.

Suppose that a trolley 3A loaded with a serving table 4A has now arrived at the starting point. Note that the command generation device 11 is connected to the terminal Q ₁
It is assumed that only the output of is "H" and all others are "L".

When the operator steps on the departure command device 7, the output of the monostable element 10, that is, the first floor call signal 10a
becomes "H", and car 8 is called to the first floor. This operation is performed by an elevator control circuit (not shown), but since it is well known, detailed explanation will be omitted. On the other hand, the signal 10a is "H"
Then, the "H" output of the terminal Q ₁ of the command generation device 11 is transferred to the next terminal Q ₂ , and the output, that is, the serving command signal 112 to the second floor becomes "H". with this,
“Second floor” is displayed on the display 6 as the destination floor of the trolley 3A. When the signal 112 becomes "H", this is wirelessly transmitted to the trolley 3A, and the trolley 3A is instructed to serve food to the second floor. The trolley 3A travels along the guide line 2 to the landing, and if the car 8 is stopped, it gets into it. Since the operation during this time is also well known, detailed explanation will be omitted. If the car 8 is on the first floor, the car position signal 12 becomes "H", and when the cart 3A gets into the car 8, the car interior detection signal 13 becomes "H", so the output of the AND gate 14 is "H". becomes. Now, the output of AND gate 15, that is, 2
The car call signal 15a on the floor becomes "H". This is similar to pressing the destination floor button for the second floor in a normal elevator car, the second floor car call is registered, and the car 8 carries the trolley 3A and travels to the second floor. When the car 8 stops on the second floor, the cart 3A gets off the car 8 and lowers the serving table 4A to a predetermined position.

Next, it is assumed that another cart 3B has arrived at the starting point. When the departure command device 7 is stepped on, the call signal 10a on the first floor becomes "H" as described above, and the "H" output from the terminal Q ₂ of the command generation device 11 goes to the next terminal Q ₃ .
Then, the serving command signal 113 for the third floor becomes "H". Now, "3rd floor" is displayed on the display 6, and the trolley 3B is transported to the 3rd floor by the cage 8.
The serving table 4B will be lowered to a predetermined position.

Thereafter, each time the departure command device 7 is operated, the output of the command generation device 11 is shifted, and a command for serving meals to the third to ninth floors is issued.

Since the departure command device 7 is not touched by hand, it is sanitary.

Note that it is also possible to implement as follows.

(a) Applicable not only to hospitals, but also to office buildings, factories, etc., for serving meals and transporting cargo.

(a) The command generation device 11 is not limited to a circulating shift register. The order of serving is stored in memory in advance, and a microcomputer is used to perform calculations. In addition, the order of serving is set using a pin board.

(c) The departure command device 7 is not limited to a foot button. For example, use one that operates by sound.

(d) For information communication with the trolleys 3A and 3B, something other than radio, such as a magnetic switch, is used.

(E) Use an audio broadcasting device instead of the display 6.

(F) As a running direction guide device for bogies 3A and 3B,
Mechanical guide devices such as guide rails and optical guide devices such as white lines and stainless steel tape are used.

As explained above, in this invention, each time the departure command device provided at the departure point is operated, the destination floor command signals stored in advance are issued in sequence, and the automatic traveling cart on the departure floor is controlled by the destination floor command signals. Since the robot is transported to the floor indicated by the elevator car using the elevator car, it is possible to transport the self-driving trolley by elevator simply by operating an inexpensive departure command device that emits a single output without requiring any troublesome operations. can.
