DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A transport system according to an embodiment of the present invention will be described below with reference to FIGS.

The transport system 1 shown in FIG. 1 is constructed on the back of the ceiling of a facility such as a hospital. The back of the ceiling is divided into fire protection zones X, Y, and Z by a plurality of fire walls 2. The transport system 1 includes a plurality of rails 3 provided continuously over each of the fire protection zones X to Z, and a transport carrier 4 (transporting means) running on each rail 3. Each rail 3 passes through the passage 5 of each fire wall 2, and the passage 5 has an opening sufficient to allow the carrier 4 to pass through. As shown in FIG. 2, the transport carrier 4 includes a carriage 7 that runs on each rail 3 via a guide roller 6.
Each rail 3 is driven by a thrust between the primary side (stator) 8 of the linear motor and the secondary side (moving element) 9 of the linear motor facing the primary side. Further, a container 10 for storing a conveyed object (such as a chart or an X-ray photograph) is attached to the cart 7 on the side opposite to the secondary side (moving element).

The fire protection zones X to Z are mutually connected or blocked by a fire damper 11 (fire protection means) which opens and closes the passage 5 of each fire wall 2 between the rails 3. Each of the fire protection zones X to Z has a smoke detector 1 for detecting the occurrence of a fire inside.
2 (fire detection means) are arranged. Each of the smoke detectors 12 detects smoke generated at the time of a fire in each of the fire protection zones X to Z.
It is connected to the. In addition, as a device for detecting the occurrence of a fire in each of the fire protection zones X to Z, a device for detecting heat or flame light at the time of a fire may be used.

The control device 13 controls the entire transport system 1 (transport carrier 4 and each fire prevention damper 11).
The transport carrier 4 travels and stops in response to a transport command from a station (not shown). The control device 13 includes a selector 14 for appropriately selecting a detection signal output from each of the smoke detectors 12 and a detection signal selected by the selector 14 to determine whether a fire has occurred in each of the fire protection zones X to Z. The fire recognizer 15 controls the opening and closing of the fire prevention shutter 11. The control device 13 includes a fire detector 15
Has a linear controller 17 for receiving a fire signal from the vehicle.
A signal (electric power) output to the primary side 9 of the linear motor for each Z and a stop 16 (mechanist) of each rail 3 is controlled to move and stop the transport carrier 4. In this configuration, the control device 13 uses the fire recognition device 15 to
Of the carrier 4 is controlled by the linear controller 17.

Next, a control method of the transport system 1 will be described with reference to FIG.
And FIG. 3 (flowchart).

When the control device 13 receives a transfer command from the station, the control device 13 controls each rail 3 via the linear controller 15.
A signal (electric power) is output to the primary side (stator) 8 of the linear motor, and the transport carrier 4 (trolley 7) is caused to travel by the thrust between the linear motor and the secondary side (moving element) 9.
Further, the fire prevention recognizer 15 also outputs an open signal to each fire prevention damper 11 to open all the fire prevention dampers 11 in advance or allows the conveyance carrier 4 to pass through the conveyance carrier 4 traveling on each rail 3. Each fire damper 11 is opened each time it passes. As a result, the transport carrier 4 travels between the stations and transports the transported objects (such as medical charts and X-ray photographs) stored in the container 10 [♯ in FIG.
1].

If a fire occurs in, for example, a fire protection area Y while sequentially carrying an article (such as a chart or an X-ray photograph) by the carrier 4, the smoke detector 12 detects smoke caused by the fire. A detection signal is output to the control device 13 (# 2, YES in FIG. 3). When the control device 13 receives the detection signal, the selector 14 selects the detection signal in the fire protection area Y from the signals of the smoke detectors 12 and outputs the signal to the fire recognition device 15.
When the fire recognizer 15 recognizes the area of the fire based on the detection signal, it outputs a fire signal to the linear controller 17 and each fire prevention shutter 11. Thereby, when each fire prevention damper 11 is closed, all the fire prevention dampers 11 are opened to allow the transport carrier 4 to travel.

Also, a fire signal is input and the linear controller 1
7 controls the output of a signal (electric power) to the primary side (stator) 8 and the stop 16 (Mekasto) of the linear motor in each of the fire protection areas X to Y, thereby controlling the travel of the transport carrier 4 and Evacuate in fire areas X and Z [# 3 in Fig. 3]. For example, when the transport carrier 4 is traveling in a fire protection area X (non-fire area) or in a fire protection area Y (fire area), the primary side of the linear motor of the fire protection area X, Y ( The signal (power) is continuously output to the stator 8, and the signal (power) is output to the stop device 16 (Mekasto) without outputting the signal (power) to the primary side (stator) 8 of the fire protection zone Z. I do. Thus, the transport carrier 4 travels from the fire protection zone Y (fire zone) to the fire protection zone Z (non-fire zone), and is stopped by the stop device 16 (mechanist) in the fire protection zone Z.

When the transport carrier 4 is retreated to the fire protection zone Z (non-fire zone) (# 4, YES in FIG. 3), the fire detector 15 outputs a close signal to all the fire protection dampers 11 and outputs The passage opening 5 of each fire wall 2 is closed by the fire damper 11 [FIG.
$ 5]. As a result, the fire protection zones X to Z are cut off from each other, and the transported object (the chart, the X-ray photograph, etc.) of the transport carrier 4 evacuated from the fire zone to the non-fire zone.
Can be protected from burning.

After shutting off the fire protection zone Y (fire zone) and the other fire protection zones X and Z (non-fire zone), the linear controller 17 again controls the primary side (stator) of the linear motor of each rail 3. ) 8 by outputting a signal (power) to the fire protection zone Z
The transport carrier 4 evacuated to the (non-fire area) travels to the station. Thus, the transported object (such as a medical chart or an X-ray photograph) stored in the container 10 of the transport carrier 4 can be removed from the station.

As described above, according to the transport system of the present invention, after the transport carrier 4 travels from the fire-prevention zone Y where the fire has occurred to the non-fire-prevention zone Z and retracts, the fire-prevention damper 11 is closed to close the fire. Since the non-fire fire protection zones X and Z are cut off from the fire protection zone Y, the transported objects (such as medical charts and X-ray photographs) stored in the container 10 of the transport carrier 4 can be protected from burning.

It is to be noted that the transport carrier 4 is not limited to the one in which the transport carrier 4 travels from the fire protection zone Y (fire zone) to the fire protection zone Z (non-fire zone) and retreats. When a fire occurs, the transport carrier 4 may be stopped at the fire protection zone X before the fire protection zone Y (fire zone) and evacuated. At this time, the linear controller 17 that has received the fire signal outputs the stop device 16 without outputting a signal to the primary side (stator) 8 of the linear motor in the fire protection area X.
Output signal (power) to (Mekasto). Thus, the transport carrier 4 traveling in the fire protection area X stops before the fire wall 2 and is retreated to the fire protection area X. And fire recognition device 1
5 closes each fire prevention damper 11 to shut off the fire protection areas X and Z (non-fire areas) from the fire protection area Y (fire area).

Further, a plurality of transport carriers 4 traveling on each rail 3 of the transport system 1 may be provided. When a fire occurs in the fire protection area Y, each transport carrier 4
To the fire protection areas X and Z (non-fire areas) and close each fire protection damper 11 to cut off each fire protection area X and Z (fire area) from the fire protection area Y (fire area). .

Further, the transport system 1 having the transport carrier 4 running on a plurality of rails 3 installed above the ceiling of the facility has been described, but the present invention is not limited to this. For example, the present invention may be applied to a transport system having a transport vehicle traveling on the ground.

[0022]

According to the present invention, if a fire occurs in any area while the transporting means is running, the transporting means is moved / evacuated to a non-fire area, and then the fire protection means is closed to remove the fire from the fire area. Since the non-fire area is shut off, it is possible to protect the transported object transported by the transporting means from burning.
