The Then, the lower end surface of the support shaft 25 of the closing plate 22 is separated from the contact portion 34 of the incineration table 14. When the lift position sensor 32 detects that the incineration table 14 has been lowered to the lowest position, the control computer 46 stops the lift raising / lowering motor 31.

  Next, the control computer 46 drives the cart moving motor 30 to move the moving cart 15 backward. The movable carriage 15 moves horizontally in the transfer passage 10 with the body 6 placed thereon, and the movable carriage 15 is moved to just below the cremation furnace 7. When the cremation position sensor 19 detects the presence of the movable carriage 15, the control computer 46 stops the carriage movement motor 30, and the movable carriage 15 is stopped immediately below the cremation furnace 7.

  And as shown in FIG. 4, the lift raising / lowering motor 31 is driven just under the cremation furnace 7, and the incineration table 14 is raised. Then, the corpse 6 is carried into the cremation chamber 38 through a loading / unloading port 43 formed in the hearth portion of the cremation chamber 38. When the lift position sensor 32 detects that the incineration table 14 has been raised to the vicinity of the uppermost position, the control computer 46 stops the lift raising / lowering motor 31.

  After carrying the body 6 into the cremation chamber 38, the control computer 46 activates the exhaust device 9 to start forced exhaust of the air in the cremation chamber 38. Further, the gas burner 39 and the assist burner (not shown) are ignited. Further, the flame nozzle of the gas burner 39 is slowly swung up and down and left and right by the gas burner control unit 40 to incinerate the tub 35 and the body 6 placed on the incineration table 14 evenly.

  When the gas burner 39 is ignited in the initial stage of the cremation, the incineration table 14 is disposed so as to be slightly lower than the uppermost position, and the volume of the space inside the cremation chamber 38 is slightly increased. Then, after a predetermined time has elapsed since the ignition of the gas burner 39, the control computer 46 drives the lift elevating motor 31 to raise the incineration table 14 to the uppermost position.

  According to the present embodiment, in the initial stage of cremation, the amount of heat generated by burning the urn 35 and the body 6 is large, and thus the temperature inside the cremation chamber 38 suddenly rises to an excessive temperature.

And wear of the ceiling wall 37 can be prevented.

  Furthermore, in the middle and later stages of cremation where cremation has progressed, the amount of heat generated by burning the urn 35 and the body 6 is reduced, so the volume of the space inside the cremation chamber 38 is reduced to reduce the heat capacity inside the cremation chamber 38. Since the fuel consumption of the gas burner 39 required to keep the temperature in the cremation chamber 38 high can be reduced by reducing the gas pressure in the cremation chamber 38, the fuel in the gas burner 39 can be saved.

  In this embodiment, the volume of the space inside the cremation chamber 38 is changed in the initial stage of cremation, but the present invention is not limited to this, and is in the middle or later stage of cremation. Alternatively, the volume of the space inside the cremation chamber 38 may be changed. For example, the volume of the space inside the cremation chamber 38 may be changed according to a change in the combustion state due to the strength of the heating power of the gas burner 39 or the like. .

  In addition, when the exhaust device 9 is operated, air flows from the intake duct 47 into the cremation chamber 38, and the air in the bone collecting chamber 2 moves between the upper surface of the bone collecting table 3 and the lower surface of the closing plate 22. 24 flows into the cremation chamber 38 through the transfer passage 10 while being regulated by the opening 21. At this time, since the opening 21 of the table 3 is blocked by the closing plate 22, it is possible not only to prevent a participant from falling into the opening 21 but also from the opening 21 of the table 3. Since excessive air flows into the transfer passage 10, adverse effects on the combustion of the gas burner 39 in the cremation chamber 38 can be avoided as much as possible.

  Further, when the body 6 is incinerated by the gas burner 39, the incineration state of the body 6 is photographed by the in-furnace camera 42 installed on the ceiling wall 37 of the cremation chamber 38, and the photographed image signal is sent to the control computer 46. Entered. The control computer 46 stores the input image, and the unburned portion of the body 6 is specified by the control computer 46 based on the image. The control computer 46 controls the flame 6 to hit the unburned portion of the body 6 by transmitting to the gas burner control unit 40 the direction of the flame nozzle of the gas burner 39 and the instruction of the heating power.

  In addition, since the amount of black smoke generated in the cremation chamber 38 can be reduced by using propane gas having a high energy value as the fuel for the gas burner 39, a clear image can be taken by the in-furnace camera 42. Further, when shooting with the in-furnace camera 42, the gas burner 39 may be temporarily stopped, and if the gas burner 39 is repeatedly stopped and re-ignited every time shooting is performed, it is not disturbed by the flame. A clear image is captured.

  When the control computer 46 confirms that the body 6 has been completely incinerated based on the image signal from the in-furnace camera 42, the control computer 46 stops the gas burner 39 and the assist burner (not shown). At this time, the operation of the exhaust device 9 is continued, and the lift raising / lowering motor 31 is driven to lower the incineration table 14. When the lift position sensor 32 detects that the incineration table 14 has been lowered to the lowest position, the lift elevating motor 31 is stopped. Further, the control computer 46 turns on an end notification lamp 45 installed in a waiting room (not shown).

  Next, the control computer 46 causes the movable carriage 15 to wait for a predetermined time at a position directly below the cremation chamber 38. Then, since the incineration table 14 is separated from the heat-resistant wall 36 and the ceiling wall 37 of the cremation chamber 38, it is cooled without being affected by the heat generated by the heat-resistant wall 36 and the ceiling wall 37. Further, since the exhaust device 9 is in operation, the external air that has flowed into the transfer passage 10 from the intake duct 47 rapidly cools the incineration table 14 and the burned bone. That is, the exhaust device 9 and the intake duct 47 constitute a cooling means in the present invention, and the cremation furnace device has such a cooling means, so that the incineration table 14 after the cremation can be quickly collected. It becomes possible to move to the table 3, and the processing capability of the cremation furnace apparatus can be improved.

  The in-furnace camera 42 can detect infrared rays emitted from the incineration table 14 and measure the temperature of the incineration table 14. When the incinerator 14 is cooled to a predetermined temperature, the control computer 46 drives the carriage moving motor 30 to move the moving carriage 15 forward. When the bone collecting position sensor 18 detects the presence of the moving carriage 15, the carriage moving motor 30 is stopped.

  Next, the control computer 46 drives the lift raising / lowering motor 31 to raise the incineration table 14 and raise the closing plate 22. The control computer 46 stops the lift raising / lowering motor 31 when the lift position sensor 32 detects that the incineration table 14 is raised to the uppermost position.

  Then, when the incineration table 14 is raised to the uppermost position, the attendees can collect the burned bones at the collecting table 3. Even if the incineration table 14 having the burned bone after the cremation is located on the table 3, the odor or dust generated from the burned bone on the incineration table 14 keeps the exhaust device 9 in operation. Thus, since the air is sucked from the gap between the opening 21 of the bone table 3 and the incineration table 14 through the transfer passage 10, these odors and dusts fill the inside of the bone collecting chamber 2 where bone collection is performed. To avoid doing as much as possible.

  As described above, according to the present embodiment, the inlet / outlet 43 for taking in / out the incinerator 14 is provided in the hearth part of the cremation chamber 38, and the incinerator 14 is moved from the inlet / outlet 43 of the hearth part by moving the incinerator 14 up and down. As a result, the odor and hot air in the cremation chamber 38 are difficult to leak out to the outside of the cradle chamber 2 and the like even when the incineration table 14 is taken in and out. The leakage can be significantly reduced compared to the conventional case.

  In addition, according to the present embodiment, the incineration table 14 moves up and down in the vertical direction on the calcination table 3, so that the corpse 6 feels as if the body 6 returns to the ground at the time of seeing off. Not only can it be given, but it can also give the feeling that the burned bone after incineration is clean and returned from the ground.
