[Control processing executed by control unit 600]
Next, control processing executed by the control unit 600 will be described with reference to the flowcharts of FIGS. 19 and 20. As shown in FIG. 19, the control unit 600 checks whether or not the power switch 606a is turned on in S11. If the power switch 606a is turned on, the process proceeds to S12 and the automatic operation switch It is checked whether 606b has been turned on. If the automatic operation switch 606b is not turned on in S12, the process proceeds to S13, and it is checked whether the manual operation switch 606c is turned on. If the manual operation switch 606c is not turned on in S13, the process returns to S12, and the processes in S12 and S13 are repeated.

  When the automatic operation switch 606b is turned on in S12, the process proceeds to S14, and the automatic operation control program stored in the storage device 602 and the roasting set temperature and roasting stored in the storage device 602 in advance. Read each value of the set time. In S13, when the manual operation switch 606c is turned on, the process proceeds to S15, and the values of the roasting set temperature and the roasting setting time input by the manual operation switch 606c are read.

  In the next S16, it is checked whether or not the roasting container carry-out switch 606g has been turned on. In S16, when the roasting container unloading switch 606g is turned on, the process proceeds to S17, and the upper door driving motor 221 and the lower door driving motor 231 of the upper opening / closing mechanism 220 and the lower opening / closing mechanism 230 constituting the opening / closing mechanism 70 are driven. The upper door 72 is raised and the lower door 74 is lowered to open the opening 31 (see FIGS. 11 and 12).

  In the next step S18, the roasting container moving drive motor 450 of the roasting container moving mechanism 120 is driven to rotate and the bearing plate 400 fixed to both ends of the rotating shaft 80 of the roasting container 50 is moved forward along the guide rail 410. Move to (A direction). As shown in FIG. 6, when the insertion port 54 and the removal port 56 of the roasting container 50 arrive at the loading / unloading position protruding forward (A direction) from the opening 31, they are moved by a stopper (not shown). At the same time, the roasting vessel moving drive motor 450 is stopped.

  Here, the worker opens the first lid 58 provided on the upper portion of the roasting container 50 to open the charging port 54, and puts the member to be roasted into the roasting container 50 from the charging port 54. Input a predetermined amount. When the operation of charging the member to be roasted is completed, the worker lowers the first lid 58, closes the charging port 54, and locks the first lid 58 to the roasting container 50 using the buckle 58b. Next, the worker operates the roasting container carry-in switch 606h to be turned on.

  In the next S19, when the roasting container carry-in switch 606h is turned on, the process proceeds to S20, and the roasting container moving drive motor 450 of the roasting container moving mechanism 120 is driven to rotate reversely to the roasting container moving mechanism 120. The bearing plates 400 fixed to both ends of the 50 rotation shafts 80 are moved rearward (in the B direction) along the guide rail 410 (roasting container carrying means: see FIG. 6). As a result, the roasting container 50 into which the member to be roasted is put is carried into the roasting chamber 20.

  In the next S21, it is checked whether or not the roasting container 50 in the roasting chamber 20 has returned to the roasting position. In S21, when the roasting container 50 arrives at the roasting position of the roasting chamber 20 and the bearing plate 400 comes into contact with the stopper and stops, energization of the roasting container moving drive motor 450 is stopped in S22. When the roasting container 50 returns to the roasting position, the drive gear 112 of the roasting container moving mechanism 120 meshes with the gears 162 formed on both sides of the roasting container 50, and the roasting container drive motor 117 rotates. It is connected in a state where the driving force can be transmitted.

  Subsequently, in S23, the upper door driving motor 221 and the lower door driving motor 231 of the opening / closing mechanism 70 are driven to lower the upper door 72, and the lower door 74 is raised to close the opening 31 (opening closing means). : See FIGS. 11 and 12).

  In next S 24, the air cylinder switching valve 610 of the roasting container holding mechanism 100 is switched to drive the piston rod 102 a of the air cylinder 102 in the axial direction, so that the taper portion 106 of the positioning member 104 is moved to the rotation shaft 80. The rotary shaft 80 is held so as not to move in the front-rear direction (A, B direction) by being fitted into the recess 86 (rotary shaft holding means: see FIG. 8).

  In S25, the roasting vessel drive motor 117 is driven to rotate (roasting vessel rotation drive means: see FIG. 9). As shown in FIGS. 8 and 9, the rotational driving force of the roasting vessel drive motor 117 is applied to the roasting vessel 50 via the sprocket 116, the chain 115, the sprocket 114, the roasting vessel drive shaft 113, and the drive gear 112. It is transmitted to the gear 162 of the rotation transmitting member 160 arranged on both sides. Therefore, the roasting container 50 is slowly rotated around the rotation shaft 80 at a preset low speed.

  In S26, gas is supplied to the gas burner 132 of the heating unit 130 by opening the gas supply valve 620, and the gas injected from the gas injection port 134 of the gas burner 132 is ignited by the gas ignition device 630 (heating means: FIG. 9). reference). As a result, the gas injected from the gas injection port 134 of the gas burner 132 burns and the high-temperature combustion gas is filled in the roasting chamber 20, and the inner wall of the roasting chamber 20 is heated by the high-temperature flame injected from the gas burner 132. The far-infrared panel 300 disposed on the ceiling is heated to a high temperature and radiates far-infrared rays toward the roasting container 50. In this manner, the roasting process for the member to be roasted that has been put into the roasting container 50 is started.

  In S27, the ventilation by the convection device 140 and the exhaust device 150 is started (convection means, exhaust means: see FIG. 10). Thereby, the hot air flow generated by the convection device 140 convects through the roasting chamber 20, passes through the numerous vent holes 51 a, and flows into the roasting container 50. Further, the steam generated inside the roasting container 50 is released into the space 40 of the roasting chamber 20 by the air flow that flows out through the numerous air holes 51a. Thus, the granular to-be-roasted member thrown into the roasting container 50 is roasted by the hot airflow which flows in by the convection inside the roasting chamber 20 with the rotation of the roasting container 50.

  Since the roasting container 50 rotates in the circumferential direction around the rotation shaft 80, all the roasted members put into the roasting container 50 are stirred by the protrusions 52 and 53 inside the drum, It is heated and roasted by the hot gas flowing in through the vent hole 51a and the far infrared rays emitted from the far infrared panel 300.

  In S28 of FIG. 20, the temperature of the roasting chamber 20 measured by the temperature sensor 640 is read. Subsequently, the process proceeds to S29, where the temperature measurement value T1 measured by the temperature sensor 640 is compared with the set temperature (target temperature) T0 stored in advance in the storage device 602. In S30, the temperature measurement value T1 is set to the set temperature T0. Check whether or not When the temperature measurement value T1 reaches the set temperature T0 in S30, the process proceeds to S31, and time measurement by a timer is started.

  In next S32, it is checked whether or not a predetermined time set in advance in the timer has elapsed. If the predetermined time has elapsed in S32, the process proceeds to S33, and the timer is reset. This completes the roasting process for all roasted members put into the roasting container 50.

  In next S34, when the detected portion 380 of the roasting container 50 is detected by the phototube 350, the energization to the roasting container drive motor 117 is stopped to stop the rotation of the roasting container 50 (rotation stopping means: (See FIG. 9). Therefore, the roasting container 50 stops at a specified angle (the angle at which the input port 54 and the output port 56 face the opening 31) at which the member to be roasted can be input and output (rotation stop means: see FIG. 9). .

  In the next S35, it is checked whether or not the roasting container carry-out switch 606g has been turned on. In S35, when the roasting container unloading switch 606g is turned on, the process proceeds to S36, and the upper opening / closing mechanism 220 constituting the opening / closing mechanism 70, the upper door driving motor 221 and the lower door driving motor 231 of the lower opening / closing mechanism 230 are driven. The upper door 72 is raised and the lower door 74 is lowered to open the opening 31 (opening opening means: see FIGS. 11 and 12).

  In the next S37, the taper portion 106 of the positioning member 104 is switched by switching the air cylinder switching valve 610 of the roasting container holding mechanism 100 and driving the piston rod 102a of the air cylinder 102 in the axial direction (the direction opposite to the holding direction). Is separated from the concave portion 86 of the rotating shaft 80 to release the holding of the rotating shaft 80 (holding release means: see FIG. 8).

  Subsequently, the process proceeds to S <b> 38, and the roasting container moving drive motor 450 of the roasting container moving mechanism 120 is driven to rotate so that the bearing plate 400 fixed to both ends of the rotating shaft 80 of the roasting container 50 is along the guide rail 410. To move forward (direction A) (roasting container carrying means). As shown in FIG. 7, when the insertion port 54 and the removal port 56 of the roasting container 50 arrive at the loading / unloading position projecting forward (A direction) from the opening 31, they are moved by a stopper (not shown). At the same time, the roasting vessel moving drive motor 450 is stopped.

  Thereafter, the worker removes the buckle 59b of the second lid 59 provided on the lower side of the roasting container 50, opens the second lid 59, and completes roasting after roasting is completed from the take-out port 56. The decoction member is accommodated in the collection container 210 (see FIG. 7).

  In the next S39, it is checked whether or not the stop switch 606d is turned on. In S39, when the stop switch 606d is not operated to be turned on, the process returns to S19 described above, and it is possible to roast a large number of members to be roasted by repeating the processes in S19 to S39.

  In S39, when the stop switch 606d is turned on, the process proceeds to S40, the gas supply valve 620 is closed to stop the gas supply to the gas burner 132 of the heating unit 130, and the convection device 140 and the exhaust device 150. Stop. In S41, it is checked whether or not the roasting container carry-in switch 606h has been turned on.

  When the roasting container carry-in switch 606h is turned on in S41, the process proceeds to S42, and the roasting container moving drive motor 450 of the roasting container moving mechanism 120 is driven to rotate reversely to the roasting container moving mechanism 120 to rotate the roasting container 50. The bearing plate 400 fixed to both ends of the shaft 80 is moved rearward (B direction) along the guide rail 410. When it is detected in S43 that the roasting container 50 has returned to the roasting position, the process proceeds to S44, where the upper door driving motor 221 and the lower door driving motor 231 of the opening / closing mechanism 70 are driven to lower the upper door 72. The lower door 74 is raised and the opening 31 is closed. Thus, the roasting apparatus 10 stops when the roasting container 50 is stored in the roasting chamber 20.
