  Also, as shown in FIGS. 9A and 9B, when the detection means 40 detects the occurrence of an earthquake and outputs a detection signal when an earthquake occurs, the control that has received the detection signal from the detection means 40 The cylinder 74 is driven by the control of the control device 13, which is a means, and the unloading means 71 moves downward from the unloading position to the avoidance position based on the driving of the cylinder 74. That is, the carry-out means 71 moves to the avoidance position by descending in a horizontal posture based on the drive of the cylinder 74.

  Next, the operation and the like of the one embodiment will be described.

  When continuous rice cooking is performed using a plurality of rice cooking pots A, each device of the rice cooking system 1 is operated, and the rice cooking pot A and the lid B are circulated along the rice cooking line.

  And at the time of this rice cooking work, the carrying-in means 61 of the continuous rice cooker 6 is located in a carrying-in position, carries the rice cooker A into the 1st conveyor part 41a of the heating apparatus main body 43, and the carrying-out means 71 of the continuous rice cooking apparatus 6 carries out. The rice cooker A is carried out from the second conveyor portion 41b of the heating device main body 43 at the position.

  However, when an earthquake occurs and the detection means 40 detects the occurrence of the earthquake and outputs a detection signal, the carry-in means 61 collides with the first conveyor section 41a of the heating device main body 43 based on the drive of the motor 63. The carry-out means 71 is lowered to the avoidance position where the collision with the second conveyor portion 41b of the heating device main body 43 is avoided based on the drive of the cylinder 74.

  For this reason, as shown in FIG. 8 and FIG. 9, when an earthquake occurs, the heating device body 43 placed on the placing plate portion 30 of the seismic isolation means 24 moves horizontally with respect to the floor 22 of the building. Even if it shakes, the heating apparatus main body 43 and the carrying-in means 61 and the carrying-out means 71 do not collide.

  In addition, after the occurrence of an earthquake is detected by the detection means 40 and the carry-in means 61 and the carry-out means 71 are avoided to the avoidance position, the operation of the rice cooking system 1 is stopped.

  On the other hand, even if an earthquake occurs and the floor surface 22 vibrates in the horizontal direction, the horizontal vibration of the floor surface 22 is absorbed by the seismic isolation means 24, so that it is directly transmitted to the heating device body 43. There is nothing.

  Further, even if the vertical vibration that causes the floor surface 22 to vibrate in the vertical direction occurs, the frame portion in the substantially U-shaped support main body portion 54 of the main body support body 53 fixed to the mounting plate portion 30 of the seismic isolation means 24. Since 44 is inserted, the heating device main body 43 is supported by the main body support body 53 so as not to be lifted, does not fall down, and even if the floor 22 is shaken violently in the horizontal direction, the heating device main body 43 is heated. Since the apparatus main body 43 is supported by the main body support body 53, the apparatus main body 43 does not move greatly with respect to the mounting plate portion 30 on the mounting plate portion 30.

  On the other hand, when the rice cooker A is heated by the heating device main body 43 (during the rice cooking operation), the heating device main body 43 has a long length due to thermal expansion based on gas combustion because the heating device main body 43 itself is long. However, there is a thermal expansion-corresponding gap 50 between the vertical plate portion 59 of the support main body portion 54 of the main body support body 53 and the vertical plate portion 49 of the frame portion 44. The heating device main body 43 and the main body support body 53 are not distorted.

  According to the rice cooking system 1, when the earthquake occurs, the carry-in means 61 of the carry-in side conveyor device 16 and the carry-out means 71 of the carry-out side conveyor device 17 drive the motor 63 and the cylinder 74 by the detection means 40. Therefore, it is possible to prevent damage caused by the collision, misalignment of the rice cooking line, and the like, and to suppress occurrence of problems due to the influence of an earthquake or the like.

  In addition, since the heating device main body 43 is placed on the mounting plate portion 10 of the seismic isolation means 24, the seismic isolation means 24 and the main body support body (earthquake-resistant metal fittings) 33 also cause problems due to the effects of earthquakes and the like. It is possible to suppress the damage and toppling of the heating device main body 43 appropriately. Moreover, since a thermal expansion-corresponding gap 50 is formed between the frame portion 44 of the heating device body 43 and the support body portion 54 of the body support body 53, it is also suitable for the thermal expansion of the heating device body 43 during heating. It can correspond to.

Incidentally, the continuous rice cooking system 6 of cooking system 1 is not limited to the gas type, but it may also in such as those of the heater type or IH formula.

Also, carry-it means 61 is moved to the avoidance position by downward rotation, not limited to the configuration unloading means 71 is moved to the avoidance position by the lowering, both transportable guide means 61 and out means 71 For example the downward rotation but it may also in the structure and the like to move to avoid position by.

  Further, the detection means 40 is not limited to the one that detects the occurrence of an earthquake based on the shaking state of the control device 13. For example, the shaking state of the mounting plate portion 30, the shaking state of the heating device main body 43, and the carrying-in means 61 It is also possible to detect the occurrence of an earthquake on the basis of the state of shaking or the state of shaking of the unloading means 71.
