Specifically, it is disposed facing the entrance of the building. The buildings include a warehouse for carrying and storing luggage therein, a factory for processing, and a ship for transportation.
Here, as an example of the building, an unmanned automatic warehouse in which management of loading, storing, unloading, and the like of luggage is entirely automatically performed by a robot will be described.

As shown in FIG. 2, the automatic warehouse includes a plurality of shelves 2 arranged in parallel inside a building 1 and a plurality of shelves 2.
Between the outside and the outside, the storage robot 3 for storing luggage in the shelf building 2 from the outside and taking out the luggage in the shelf building 2 to the outside.
And a transport robot 4 that transports the load carried in from the entrance 1A of the building 1 to the loading / unloading robot 3 and transports the load taken out of the shelf building 2 by the loading / unloading robot 3 to the exit 1B. I have. In this building 1, a smoke detector and a fire extinguisher (both not shown) are provided as in the prior art. These putting-in / out robot 3, transfer robot 4, smoke detection device and fire extinguishing device are controlled by a control device (not shown).

At the entrance 1A of the building 1, there is provided a fire detection device 5 as fire detection means for detecting the presence or absence of a fire in the loaded luggage. As shown in FIG. 1, the fire detection device 5 has a gate shape communicating with the carry-in entrance 1A. That is, it is configured in a gate shape with side walls 6 and 7 that partition both sides and a ceiling 8 that partitions the upper side. The ceiling part 8 is formed in a mountain shape. A shielding plate 9 (only the front shielding plate is shown in FIG. 1) is provided before and after the ceiling portion 8. The mountain-shaped ceiling portion 8, the side wall portions 6, 7 on both sides, and the front and rear shielding plates 9 form an air intake portion 10 for taking in the air around the passing baggage. An exhaust port 11 and an exhaust fan 1
2 are provided. The exhaust fan 12 discharges the air in the air intake unit 10 from the exhaust port 11 to the outside, so that the air in the fire detection device 5 (existing around the luggage that has passed through the fire detection device 5). The air containing the smoke from the luggage) is efficiently taken into the air intake unit 10.

A smoke detector 15 is provided on the side wall 6. The smoke detector 15 has a main body portion 16 installed facing the side wall portion 6, and extends from the main body portion 16 to the inside of the air intake portion 10, and a front end portion faces the inside of the air intake portion 10. And a pipe 17 arranged in a state.
The main body 16 includes a fan (not shown) that sucks air in the air intake unit 10 through a pipe 17 and a smoke detection unit (not shown) that detects smoke particles from the air sucked by the fan. ). Thereby, the air in the air intake section 10 is sucked into the main body section 16 via the pipe 17 by the fan, and the presence or absence of smoke is detected by the smoke detection section at the main body section 16 with ultra-high sensitivity. It has become so. Further, the main body 16 is provided with an alarm function, and emits an alarm when smoke is detected. Further, the main body 16 is connected to the control device that controls the transfer robot 4 or the like by wire or wirelessly. The control device stops the transfer robot 4 by detecting smoke in the main body 16 so that luggage containing a fire is not carried into the interior of the building 1.

A roller conveyor 18 is provided in the gate type fire detecting device 5. The luggage passes through the fire detecting device 5 on the roller conveyor 18, and the presence or absence of the fire is detected.

[Operation] The fire prevention apparatus configured as described above operates as follows.

The loading / unloading work in the building 1 is controlled by the control device. Specifically, the luggage carried from the outside is carried into the building 1 through the carry-in entrance 1A, passes through the fire detection device 5, and is passed to the transfer robot 4. The transfer robot 4 transfers the received luggage to the designated loading / unloading robot 3, and the loading / unloading robot 3 stores the received luggage in the designated shelf in the shelf building 2.

When taking out the luggage stored in the shelves of the shelf building 2, the loading / unloading robot 3 takes out the luggage from the specified shelves in the designated shelf building 2 and conversely carries out the transfer robot. Pass to 4. The transport robot 4 transports the delivered package to the exit 1B. And the exit 1
It is taken out from B.

Each of the packages passes through the fire detection device 5 when the baggage is carried in. The fire detection device 5 detects whether there is any fire in the passing bag. Specifically, the luggage is passed through the fire detection device 5 on the roller conveyor 18. At this time, the exhaust fan 12 of the fire detection device 5 rotates, and the air in the air intake unit 10 is discharged from the exhaust port 11 to the outside. Accordingly, the air in the fire detection device 5 flows into the air intake unit 10. Thereby, the air around the passing luggage is taken into the air intake unit 10.

In the air intake section 10, the intake air is sucked by the smoke detector 15. Specifically, the air in the air intake unit 10 is sucked through the pipe 17 by the fan in the smoke detector 15. The sucked air flows into the main body 1
The smoke detector 6 detects with ultra-high sensitivity whether or not smoke fine particles are mixed in the air.

At this time, if the intrusion of smoke is detected, the alarm function warns that luggage including a fire has been brought into the building 1. At the same time, the transport robot 4 is stopped by the control device to prevent the load from being carried into the interior of the building 1. Then, the worker performs a fire extinguishing activity by specifying the luggage including the type of fire.

[Effects] As described above, even when luggage containing a fire is carried into the building 1 from the outside, the fire is detected by the fire detection device 5 to prevent it from being stored in the shelf building 2. Therefore, the occurrence of fire can be prevented beforehand, and the safety of the automatic warehouse can be improved.

In the fire detection device 5, an air intake unit 10 is provided just above the passing baggage to collect the air around the baggage. Therefore, when smoke is mixed in the air around the baggage, The smoke can be collected efficiently before it is spread and diluted. Thereby, even a small amount of smoke generated from the luggage can be efficiently collected. As a result, a small fire can be reliably detected, and the occurrence of a fire can be prevented.

[First Modification] In the above embodiment, the fire detection device 5 is provided with only the smoke detection function. However, the fire detection device 5 may be provided with a fire suppression function in addition to the smoke detection function. Specifically, as shown in FIG. 3, a fire extinguisher 21 may be provided after the fire detector 5. This fire extinguisher 21
Like the fire detection device 5, a fire extinguisher injection device (not shown) is formed in a gate shape and blows out water for fire extinguishing, fire extinguishing gas, chemical extinguishing agent, and the like. This fire extinguishing agent injection device is connected to the smoke detector 15 of the fire detection device 5,
When smoke is detected by the smoke detector 15, a fire extinguishing operation is performed in conjunction therewith.

Thus, when the smoke detector 15 detects a fire, the fire extinguisher injection device is activated immediately to extinguish the fire in the luggage and prevent the fire from being carried into the building 1.

As a result, a small fire can be prevented from being carried into the building 1, and a fire can be prevented from occurring.

[Second Modification] In the above embodiment, the fire detection device 5 is constituted by using the smoke detector 15 for detecting the presence or absence of smoke, but the infrared detector (FIG. (Not shown). As the infrared detector, an infrared sensor or an infrared camera is used.
Using this infrared detector, the presence or absence of a fire is detected, and when a fire is detected in the baggage, an alarm is issued or the transport robot 4 is stopped, as in the above embodiment.

Since the infrared detector detects heat generated by the fire in the luggage, the fire can be detected even when the fire has not yet generated smoke. As a result, it is possible to more reliably prevent the fire from being brought into the building.

When using this infrared detector,
The air intake unit 10, the exhaust port 11, the exhaust fan 12, and the like become unnecessary. Further, the fire extinguisher 21 of the first modified example may be provided integrally.

Further, since light generated by heat includes not only infrared rays but also ultraviolet rays, an ultraviolet ray detector may be used instead of an infrared ray detector.

[Other Modifications] (1) In the above embodiment, only the presence or absence of a fire is detected by the fire detection device 5, but a package appearance detecting means may be provided. That is, a package appearance detecting means for detecting the appearance of the cargo passing through the fire detection device 5 and detecting the presence or absence of collapse of the cargo may be provided. Specifically, as the package appearance detecting means, a contact type or non-contact type sensor detects the width of the package, and if there is an abnormality in the width, it is determined that the package has collapsed. There is a method in which a contour is captured as a video image, and if there is an abnormality in comparison with a preset contour, it is determined that a load collapse has occurred.

The package appearance detecting means detects the package appearance of the baggage passing through the fire detection device 5, and detects whether the cargo has collapsed. If the cargo has collapsed, stop carrying the luggage.

(2) In the fire detection device 5, a carry-in means such as a carry-in device for carrying in the load continuously at a constant interval may be provided upstream of the flow of the load. This loading means includes

Further, the fire detection device 5 may be connected to a control device in the building 1 by wire or wirelessly without having an alarm function, and may be interlocked with them.

Further, the fire detecting device 5 is constructed so as to be carried as a single unit, and the carry-in entrance 1 at a required position when necessary.
A may be installed and used. in this case,
As described above, the fire detection device 5 may be connected to the control device so as to be linked with the control device, or may be operated independently.

(4) In the above embodiment, the fire detection device 5 is provided facing the inside of the entrance 1A of the building 1, but it goes without saying that the fire detection device 5 may be provided outside.

Further, it may be arranged in close contact with the carry-in port 1A or may be arranged at a certain distance from the carry-in port 1A. When a certain distance is left, the vehicle is arranged facing the transport route of the load inside and outside the building 1 in a state facing the entrance 1A.

Further, when the fire detection device 5 is installed in the building 1, the fire detection device 5 may be installed on the transport path from the loading / unloading port 1A to the robot 3.

Also in these cases, the presence or absence of a fire can be reliably detected by the fire detection device 5, and the same effect as in the above embodiment can be obtained.

(5) In the above embodiment, the air intake unit 10 of the fire detection device 5 is provided on the ceiling 8. However, the air intake unit 10 is not limited to the ceiling 8, but may be provided on the side walls 6, 7. Or both.

(6) In the above embodiment, the automatic warehouse has been described as an example of a building.
The fire prevention device of the present invention can be used. That is, even in the case of a factory where parts and other luggage are carried inside and processed by a robot or the like, or in the case of a ship or the like that loads and transports luggage onboard.
By using the fire prevention device of the present invention in the carry-in entrance 1A, the same operation and effect as in the above embodiment can be obtained.

(7) As means of transportation to the building 1,
There are various means such as trucks, transport robots, unmanned or manned transport vehicles, belt conveyors, and the like. Further, even in the building 1, as the transporting means from the loading entrance 1A to the loading / unloading robot 3, not only the transporting robot 4, but also various transporting means such as the unmanned or manned transporting vehicle and a belt conveyor can be used.
