When the electromagnetic solenoid SL102 is energized, the water supply valve 123 is turned on for a predetermined time, and tap water supplied through the pipe 122 is used for deicing sprinkler 121.
Is supplied to the ice making water tank 111 and flows down along the back surface of the ice making plate 112. When the ice making water tank 111 is filled with the ice making water after a predetermined time has elapsed from the start of the inflow of water, the microcomputer 141 causes the electromagnetic solenoid SL to
The water supply valve 123 is turned off by deenergizing 101. Further, the rotation of the electric motor M101 is continued thereafter,
The compressor 114 compresses the refrigerant from the outlet of the evaporator 113, circulates the refrigerant in the refrigeration circuit including the condenser 115, the expansion valve 116 and the evaporator 113, and also supplies the refrigerant to the hot gas valve 118.

Next, the microcomputer 141 executes an ice making start process at step 204. In this process, the microcomputer 141 rotates the electric motor M102 and rotates the electric motor M103 in the normal direction. Due to the rotation of the electric motor M102, the cooling fan 117 rotates to start cooling the condenser 115 with air. In addition, the normal rotation of the electric motor M103 causes the circulation pump 125 to normally rotate to supply the ice making water in the ice making water tank 111 to the ice making water sprinkler 124 through the pipe 126,
The ice-making water is poured onto the surface of the ice-making plate 112. The ice making water is cooled from the back surface of the ice making plate 112 by the refrigerant supplied to the evaporator 112, and starts to freeze on the surface of the ice making plate 112. Of the ice making water sprinkled from the ice making sprinkler 124, water that has not frozen on the surface of the ice making plate 112 flows into the ice making water tank 111 again.

After the processing of step 204, the microcomputer 1
In step 206, the timer value ICTM for measuring the time from the start of ice making is initially set to "0" at step 206, and the circulation processing including steps 208 and 210 is executed. In step 208, it is determined whether five minutes have elapsed from the start of the ice making operation based on the timer value ICTM, and step 210
At, it is determined whether or not the flag RISI for instructing the stop of the ice making device A1 on the right side is "1". This timer value ICTM is set in step 3 of the "interrupt program" which is started in step 300 of FIG.
The number is incremented by "1" at 02.
The flag RISI is output from the bagging device B and is set to "0" in the normal operating state. Therefore, during the circulation process including the steps 208 and 210, the normal steps 208 and 210 are continued until 5 minutes have elapsed after the ice making operation is started, and when the same 5 minutes have elapsed, the microcomputer 141 executes the step 208. Is determined to be "YES" and the program proceeds to step 212. In step 212, the detection switch SW102
It is determined whether or not the ice making is completed based on the state of.
As described above, when the ice frozen on the surface of the ice making plate 112 gradually increases, the amount of water in the ice making water tank 11 decreases and the detection switch SW102 is turned off. In response to the OFF operation of the detection switch SW102, the microcomputer 141 deenergizes the electric motors M102 and M103. As a result, the cooling fan 115 and the circulation pump 125 are stopped, and the ice making operation is completed.

Next, the microcomputer 141 executes a deicing process in step 216. In this deicing process, the microcomputer 141 first energizes the electromagnetic solenoids SL101 and SL102. When the electromagnetic solenoid SL101 is energized, the hot gas valve 118 is turned on and hot gas starts to be supplied to the evaporator 113. Further, when the electromagnetic solenoid SL102 is energized, the water supply valve 123 is turned on, and tap water is supplied to the deicing sprinkler 12.
From 1 on, the supply to the back surface of the ice making plate 112 starts. As a result, the ice making plate 112 is warmed and the ice generated on the surface of the ice making plate 112 gradually begins to separate from the same surface. And
The ice away from the surface of the ice making plate 112 is the draining plate 136.
It drops up and is guided to the hopper 135 through the plate 136, and the hopper 135 drops the ice into the tank 41a on the right side of the bagging apparatus B. Then, when all of the ice on the ice making plate 112 has fallen, the temperature near the outlet of the evaporator 113 becomes higher than a predetermined temperature, and the detection switch SW101 is turned on. In response to the ON operation of the detection switch SW101, the microcomputer 141 releases the energization of the electromagnetic solenoids SL101 and SL102 and ends the deicing process. In this case, the water used for deicing is stored in the ice making water tank 111 as ice making water and is used for the next ice making.

After the processing of step 216, the microcomputer 1
In step 218, 41 determines whether the flag RISI is "1" as in step 210. In this case also, since the flag RISI is set to "0", the microcomputer 141 determines "NO" in step 218 and advances the program to step 220. Microcomputer 141
Sets the flag RIST for indicating that the ice making device A1 has stopped operating by "1" in step 220 to "0", and inputs / outputs a signal indicating the flag RIST set to "0". Output to the bagging apparatus B via the circuit 144. The bagging device B takes in the signal representing the output flag RIST by the input / output circuit 85. Step 22
After processing 0, the microcomputer 141 executes the program in step 2
After returning to 04, the circulation process including steps 204 to 220, that is, the sequence operation including the ice making operation and the deicing operation of the ice making device A1 is repeatedly controlled to automatically produce ice, and the tank on the right side of the bagging device B is 41a. This one-cycle sequence operation requires about 30 minutes, and three to four ice cubes are put in the bag F into the tank 41a in the same one cycle.

On the other hand, the left ice making device A2 operates in the same manner as the ice making device A1 to automatically produce ice, and
The manufactured ice continues to be put into the tank 41b on the left side of the bagging device B. In this case, the microcomputer 141
In steps 210, 220, 222 marked with * in FIG. 4, the ice making device A2 on the left side is replaced with the flags RISI, RIST.
Use the flag LISI, LIST for.

On the other hand, at the same time, the microcomputer 81 of the bagging apparatus B starts the execution of the "main program" in step 400 of FIG. 18 and repeatedly executes the circulation processing of steps 402 to 414. In this circulation processing, the microcomputer 81 sets the timer value BKTM for measuring the operation time of the bagging device B to "0" in step 402.
Initially set to, and in step 404 the detection switch SW6
It is determined whether or not one of L and SW7L is turned off, that is, whether or not one or more of the left and right tanks 41a and 41b has a bag or more of ice. in this case,
If one bag or more of ice remains in one of the tanks 41a and 41b, the microcomputer 81 makes a “YES” determination in step 404 to advance the program to step 406 and subsequent steps, and to store either of the tanks 41a and 41b. Pack the ice in one bag. If there is not more than one bag of ice remaining in both tanks 41a and 41b, the microcomputer 81
Is determined to be “NO” in step 404 and step 40
The cyclic processing consisting of 2,404 is repeatedly executed.
As a result, when there is no ice to be packed in the tanks 41a and 41b, the bag packing device B is not operated wastefully.

The microcomputer 81 executes an origin return process in step 406. In this process, the bag loading mechanism 2
0 main arm 21 is in the original position (state of FIG. 8),
It is detected whether the seal bar 52 of the seal mechanism 50 is at the upper position (state of FIG. 8) and the left and right ends of the base 61 of the drop mechanism 60 are at the upper position (state of (B) of FIG. 23). It is determined by the ON state of the switches SW2, SW8, SW10, SW13. If the left and right ends of the main arm 21, the seal bar 52 or the base 61 are not in the above positions, the microcomputer 81
Controls the rotation of the electric motors M1, M4, M5, M6 based on the signals from the detection switches SW2, SW8, SW10, SW13 to set the left and right ends of the main arm 21, the seal bar 52 or the base 61 to the above positions. To do.

Next, the microcomputer 81 executes a bag carry-in process for carrying in one of the many bags F housed in the bag housing mechanism 10 above the base 61 in step 408. In this process, first, the electric motor M1 is normally rotated. By the normal rotation of the electric motor M1, the main arm 21 starts to rotate counterclockwise in the drawing from the original position (state of FIG. 8). In this case, the sub arm 22 and the release lever 28 also rotate together with the main arm 21 in the positional relationship shown in the center of FIG. 16, and the front surface of the plate 24 fixed to the sub arm 22 contacts the bag F housed in the cassette 11. The rotation of the arm 21 stops at the point of contact. Since then,
Since the electric motor M1 continues to rotate normally, the main arm 21 continues to rotate further by the action of the leaf springs 23a and 23b, and pushes the pins 26, 26 forward against the springs 27, 27. This causes the swing levers 25, 25 to rotate, and as shown on the left side of FIG. 16, the rear side surface of the one bag F on the most front side among the many bags F accommodated in the cassette 11. Are sandwiched between the movable claws 25a, 25a and the fixed claws 24a, 24a formed on the plate 24, respectively. That is, the chuck mechanism 20a grips the upper two places on the rear side surface of the bag F. On the other hand, in this state, the main arm 2
1 is located in front of the sub-arm 22, and the detection switch SW3 is turned on. In response to the turning on of the detection switch SW3, the microcomputer 81 stops the normal rotation of the electric motor M1. At this time, the springs 27, 27 urge the swing levers 25, 25 toward the fixed claws 24a, 24a,
Fixed claws 24a, 24a and movable claw 25 are provided on the rear side of the bag F.
It is held between a and 25a.

Then, two seconds after the stop control of the electric motor M1, the microcomputer 81 reverses the electric motor M1.
Due to the reverse rotation of the electric motor M1, the main arm 21 rotates clockwise in FIG. 8 to return to the original position, and at the same time,
The sub arm 22 also rotates in the same direction as the main arm 21 and returns to the original position. The return of the main arm 21 to the original position turns on the detection switch SW2, and in response to this ON operation, the microcomputer 81 stops the reverse rotation of the electric motor M1. At this time, since the chuck mechanism 20a still holds the rear side surface of the bag F, the bag F is held by the bag support shaft 3
16 and the stopper pieces 31a, 3 are attached to the attachment piece Fa on the front side surface of the bag F as shown on the right side of FIG.
The upper opening is widened by abutting on 2a.

Next, the microcomputer 81 executes an ice input weighing process in step 410. In this process, first, the microcomputer 81 reverses the electric motors M5 and M6 to set the base 61 to the central height position based on the signals from the detection switches SW11 and SW14 (see FIG. 23A). next,
The microcomputer 81 normally rotates the electric motor M2 or the electric motor M3. As a result, the right auger 43a or the left auger 4
3b starts to rotate, and the right tank 41a or the left tank 41
The ice in b is sequentially conveyed upward through the right conveyance chute 42a or the left conveyance chute 42b and begins to be thrown into the bag F supported by the bag support shafts 31 and 32. In this case, if both detection switches SW6L and SW7L are off and there is more than one bag of ice in both tanks 41a and 41b, in order to alternately insert ice from both tanks 41a and 41b. , The electric motor M2 or the electric motor M3 is alternately rotated in the forward direction for each circulation process including steps 402 to 414. On the other hand, only one of the detection switches SW6L and SW7L is off, and one of the tanks 41a and 41
When there is more than one bag of ice only in b, only the electric motor M2 or electric motor M3 on the side where the switches SW6L and SW7L are off is rotated in the normal direction. At the same time when the ice is thrown, the base 61 is raised to the upper position by the forward rotation of the electric motors M5 and M6, and the load of the ice thrown into the bag F is not applied to the bag support shafts 31 and 32. The entire load should be supported only by the base 61 (measuring plate 72).
After raising the base 61 to the upper position (see (B) of FIG. 23), when the ice in the bag F reaches a predetermined amount (3.6 kg corresponding to one full bag) by the introduction of the ice, the detection switch SW
16 turns on. In response to the ON operation of the detection switch SW16, the microcomputer 81 stops the forward rotation of the electric motor M2 or the electric motor M3 to stop the charging of the ice bag F from the right tank 41a or the left tank 41b. .

Next, in step 412, the microcomputer 81 executes a sealing process for sealing the upper portion of the bag F containing ice supported by the bag support mechanism 30. In this process, first, the electric motor M4 is normally rotated. The forward rotation of the electric motor M4 causes the seal bar 52 to move to the support shaft 5
4 is rotated counterclockwise in FIG. 8 (see FIG. 22).
(A) to (C)), the bar 52 is a bag support shaft 31,
The upper part of the front side of the bag F that is locked to 32 is attached to the shaft 3
The heater block 51 is rotated along with the clockwise rotation of 1, 32.
Move towards. At this time, since the chuck mechanism 20a is in a state of grasping the upper portion of the rear side surface of the bag F, the seal bar 52 sandwiches the upper portion with the heater block 51 in a state where the front side surface and the rear side surface of the bag F are aligned. On the other hand, at substantially the same time as this sandwiching, the seal bar 52 causes the bag loading mechanism 20
Since the release lever 28 is pushed clockwise in FIG. 8, the upper side of the lever 28 pushes the pins 26, 26 to the right in FIG. As a result, the swing levers 25, 25 are rotated to release the holding of the bag F by the movable claws 25a, 25a, that is, the holding of the bag F by the chuck mechanism 20a is released. In this released state, the main arms 21, the sub arms 22, the swing levers 25, 25, etc. are kept in the central state of FIG. 16 by the action of the springs 27, 27.
Further, in this state, the detection switch SW9 for detecting that the seal bar 52 is at the lower position is turned on, and the microcomputer 81
Stops the forward rotation of the electric motor M4 in response to the switch SW9 being turned on.

Next, the microcomputer 81 uses the heater block 51.
The heater 51a therein is energized for 0.6 seconds. This allows
Bag F sandwiched between heater block 51 and seal bar 52
The upper part of the is melted, the front side surface and the rear side surface are adhered, and the bag F is sealed. Next, the electric motor M4 is reversed. By the reverse rotation of the electric motor M4, the seal bar 52, the support arm 53 and the like are moved upward contrary to the above, and are returned to the upper position (state of FIG. 22A). In this case, the detection switch SW8 is turned on as the drive arm 56 returns to the upper position, and the microcomputer 81 stops the reverse rotation of the electric motor M4 in response to the ON operation of the switch SW8. Then, in this state, the bag F is placed on the weighing plate 72 provided on the base 61 in a state in which a predetermined amount of ice is packed.

Next, the microcomputer 81 executes a bag drop process for dropping the bag F containing ice into the stocker C in step 414. In this process, first, the electric motors M5 and M6 are driven in reverse, and the base 61 is lowered by the action of the links 62 to 65. In this case, the base 61 is initially in the upper position as shown in FIG.
Descends to the lower position shown in FIG. 23 (C). In this state, the detection switches SW12, SW15 are turned on, and the microcomputer 81 responds to the ON operation of each switch SW12, SW15 by the electric motor.
Stop the reverse rotation of M5 and M6 respectively. Next, the microcomputer 8
1 rotates the electric motor M6 (or the electric motor M5) in the normal direction. As a result, the left end (or right end) of the base 61 rises, and the bag F containing the ice slides down from the base 61 and falls into the stocker C as shown in FIG. The ascent of the left end (or right end) of the base 61 is continued until the left end (or right end) reaches the upper position. Base 6
When the left end (or right end) of 1 reaches the upper position as shown in (E) of FIG. 23, the detection switch SW13 (or detection switch SW10) is turned on, and the microcomputer 81 responds to the ON operation of the switch SW13. The normal rotation of the electric motor M6 (or the electric motor M5) is stopped. After that, the microcomputer 81
Is an electric motor M in cooperation with the detection switches SW11 and SW14.
5, M6 is rotated to move both ends of the base 61 to the center position.

After the processing of step 414, the microcomputer 8
1 returns the program to step 402, and step 4
The cyclic processing of 02 to 414 is repeatedly executed. Thus, the microcomputer 81 carries in the bag F by the bag carry-in mechanism 20 including steps 406 to 414, and the weighing mechanism 7
0, the ice accommodating and charging mechanisms 40A and 40B for charging ice into the bag F until a predetermined amount of ice is detected, the sealing mechanism 50 sealing the bag F, and the dropping mechanism 60 dropping the bag F. A sequence of operations is repeatedly controlled to sequentially pack a predetermined amount of ice into each bag, and the packed ice is sequentially stored in the stocker C one bag at a time.

Next, the case where the stocker C is almost full of ice will be described. In this case, the detection switch SW17
Is turned on, the microcomputer 81 determines “YES” in step 506 of the “interrupt program” of FIG. 19 which is interrupted and executed at predetermined intervals during the circulation processing of the “main program”, and the program is executed in step 508. Proceed to. In step 508, the microcomputer 81 sets the flags RISI and LISI to "1", and
The signals representing the flags RISI and LISI set to "1" are output to the ice making devices A1 and A2 via the input / output circuit 85.
The ice making devices A1 and A2 take in the signal representing the output flag RIST by the input / output circuit 144. Next, the microcomputer 81 returns to the execution of the “main program” after the processing of steps 510 to 554, and executes the above-mentioned steps 402 to 41.
Continue to control the bagging of ice by the circulation process consisting of 4.

On the other hand, in the ice making devices A1 and A2, if the microcomputer 141 does not perform the circulation processing of steps 208 and 210 of FIG. 4, that is, if 5 minutes have not elapsed from the start of the ice making operation, the flag RISI, Based on the LISI, it is determined to be "YES" and the program proceeds to step 224. In step 224, the same ice making end processing as in step 214 described above is executed. Then, the microcomputer 141 again determines "YES" in step 218, that is, the flags RISI and LISI are "1", and continues to execute the circulation process including steps 218 and 222.
As a result, the processes of steps 204 to 216 are interrupted, and the ice making devices A1 and A2 stop the production of ice. Also,
If 5 minutes or more has elapsed from the start of the ice making operation, the microcomputer 141 continues to execute the circulation process including steps 218 and 222 after the processes of steps 212 to 216. Therefore, in this case, the ice making devices A1 and A2 stop the ice making after dropping the ice being made into the bagging device B, so that the ice that has started to be made is not wasted. During the cyclic processing including the steps 218 and 222, the microcomputer 141 sets the flag RIST, LIST to "" in step 222.
Flag set to "1" and set to "1"
The signal representing RIST, LIST is output to the bagging device B via the input / output circuit 144. The bagging device B takes in the signal representing the flag RIST, LIST at the input / output circuit 85.

Returning to the explanation of the bagging device B again,
Since the device B continuously packs ice as described above, when the ice in the tanks 41a and 41b is reduced to less than one full bag, the detection switches SW6L and SW7L are turned on. In this way, the signal representing the flag RIST set to "1" is input and the detection switch SW
When 6L is turned on, the microcomputer 81 determines "YES" in steps 510 to 514, respectively, on the condition that the flag RWVO indicating that the right water supply valve 46a is turned on is not "1", and then the program is stepped. Proceed to 516.
The microcomputer 81 determines in step 516 the electromagnetic solenoid SLa.
Energize, set flag RWVO to "1", and set timer value
Initialize RWTM to "0". This electromagnetic solenoid SLa
When water is energized, the water supply valve 46a is turned on to supply tap water to the water sprinkler 45a, and the water sprinkler 45a starts to water the ice in the tank 41a. Further, since the flag RWVO is set to "1", it is determined to be "NO" in the subsequent determination processing of step 510 and the processing of step 516 is not executed, and the timer value RWTM is set to "0" by the processing of step 502. From “”, it starts to rise by “1” every predetermined time. Then, when 10 minutes have elapsed from the watering, the microcomputer 81 releases the energization of the electromagnetic solenoid SLa and sets the flag RWVO by the processing of steps 542 to 546 in FIG.
Therefore, after the ice making devices A1 and A2 are stopped, the ice remaining in the tank 41a is packed in the bag and accumulated in the stocker C, and the small amount of ice remaining in the tank 41a is melted and discharged. Since the ice is not left in the tank 41a for a long time, the ice is not stored in the tank 41a.
It will not solidify inside.

When a signal representing the flag LIST set to "1" is input and the detection switch SW7L is turned on, the flag LWVO indicating that the left water supply valve 46b is turned on is not "1". Under the conditions, the microcomputer 81 is sprinkled with water for 10 minutes toward the small amount of ice remaining in the tank 41b by the processing of steps 518 to 524, step 502, and steps 548 to 552. Therefore, in this case as well, after the ice making devices A1 and A2 are stopped, the ice remaining in the tank 41b is bag-packed and accumulated in the stocker C, and the small amount of ice remaining in the tank 41b after that is melted and discharged. Therefore, the ice is not left in the tank 41b for a long time, and the ice is not solidified in the tank 41a. On the other hand, as described above, when the ice remaining in each of the tanks 41a and 41b becomes less than the full amount of ice, the microcomputer 81 continues to execute the circulation process including steps 402 and 404 in the "main program",
The ice bagging operation consisting of steps 406 to 414 is stopped. Therefore, also in this case, when the ice to be packed in the bag F does not exist in the tanks 41a and 41b, the operation of the bag packing device B is stopped.

As described above, according to the above-described embodiment, the detection switch SW17 is attached slightly downward from the upper end of the stocker C, and in response to the detection of the detection switch SW17, a slight margin (for 6 to 10 bags). When the ice is almost filled in the stocker C, the ice making devices A1 and A2 stop producing ice, and the tanks 41a and 4 of the bag filling device B are stopped.
Since the bagging device B is stopped after the ice in 1b is dropped into the stocker C, the packed ice does not overflow from the stocker C, and at the same time, the bagging device B
The ice already existing in the tanks 41a and 41b is not wasted.

When the packed ice in the stocker C is carried out, the detection switch SW17 is turned off again.
By turning off this detection switch SW17, the microcomputer 81
Determines "NO" with the switch 506 in FIG. 19 and advances the program to steps 526 and 528 in FIG. In step 526, it is determined whether or not the detection switch SW6H is turned on, and in step 528, the flag
It is determined whether RWVO is "1". In this case, no ice remains in the tank 41a, so the detection switch SW
6H is off. Further, the flag RWVO is set in the step 5 above.
It is returned to "0" by the processing of 46. Therefore,
The microcomputer 81 performs "N
"O" and the flag RISI is set to "5" in step 532.
The signal indicating the flag RISI that has been returned to "0" is output to the ice making device A1 via the input / output circuit 85. The ice making device A1 takes in the signal indicating the flag RISI at the input / output circuit 144. As a result, the microcomputer 141 of the ice making device A1 determines “NO” in step 218 of FIG. 4, resets the flag RIST to “0” and resets the flag RIST to “0” in step 220. The signal indicating the output is output to the bag packing apparatus B via the input / output circuit 144. After the process of step 220, the microcomputer 141 returns the program to step 204, and thereafter, the circulation process of steps 204 to 220 is executed to start the production of ice by the ice making device A1.

After the processing of step 532 of FIG. 20, similarly to the above, the microcomputer 81 sets "7" based on the detection switch SW7H which is off in steps 534 and 536 and the flag LWVO set to "0". When it is determined to be "NO", the flag LISI is returned to "0" in step 540, and a signal representing the flag LISI returned to "0" is output to the ice making device A2 via the input / output circuit 85. as a result,
Similarly to the above, the microcomputer 141 of the ice making device A2 also starts the production of ice. And such an ice making device A1, A
2 starts to produce ice, the ice is put into the tanks 41a and 41b of the bagging apparatus B, and the detection switch SW6
If either L or SW7L is turned off, the microcomputer 81 of the bagging device B is "YES" in step 404 of FIG.
Then, the above steps 406 to 41 are performed.
By the processing of 4, the bag packing operation of ice by the bag packing device is controlled.

Next, the tanks 41a, 41 of the bag filling device B
The case where the ice is full in b will be described. In this case, the detection switches SW6H and SW7H are turned on. This allows
The microcomputer 81 determines “YES” in steps 526 and 534 of FIG. 20 and executes the program in steps 530 and 5
38 respectively. The microcomputer 81 performs step 53
The flags RISI and LISI are set to "1" at 0 and 538, and signals representing the flags RISI and LISI set to "1" are output to the ice making devices A1 and A2 via the input / output circuit 85, respectively. . With this, as in the case described above,
The ice making devices A1 and A2 stop the production of ice. Therefore, it is possible to prevent the ice from overflowing from the tanks 41a and 41b. On the other hand, even when the ice making device A1 or A2 stops producing ice, the bag filling device is in operation, and if this operation reduces the ice in the tanks 41a and 41b, the detection switches SW6H and SW7H are turned off. The microcomputer 81 makes a "NO" determination in steps 526 and 534, respectively. At this time, since the flags RWVO and LWVO are still set to "0", the microcomputer 81 determines in step 52
8,536, "NO" determination, step 532,54
At 0, the flags RISI and LISI are returned to "0" and the same "
The signals representing the flags RISI and LISI returned to 0 "are output to the ice making devices A1 and A2 via the input / output circuit 85. This allows the ice making device A to operate in the same manner as described above.
1, A2 resumes ice production.

Finally, the case where an abnormality occurs in the bag filling device B will be described. The device B normally completes one ice bag filling cycle in about 3 minutes. Microcomputer 8
1 is steps 402 to 414 corresponding to the one cycle
Since the timer value BKTM is initialized to "0" for each circulation process consisting of, if the bagging device B is operating normally,
The timer value BKTM does not become so large.
Now, it is assumed that an abnormality has occurred in the bagging device B and a very large time (for example, 10 minutes) has been spent in one cycle. In this case, since the timer value BKTM is not initialized to "0" for a long time, the value of the timer value BKTM becomes large every predetermined time by the process of step 502 of FIG.
BKTM is greater than or equal to 10 minutes. Accordingly, the microcomputer 81 determines “YES” in step 504, outputs a signal indicating an abnormality to the alarm device 83 in step 556, and outputs the signal via the input / output circuit 85 to the ice making devices A1 and A2. Output to. As a result, the warning device 85
Informs that an abnormality has occurred in the bagging device B. Further, the ice making devices A1 and A2 output the signal to the input / output circuit 144.
Take in.

After the processing of step 556, the microcomputer 8
1 sets the electromagnetic solenoids SLa and SLb to 80 in step 557.
The power is turned on for a minute, and the execution of the program is stopped in step 558. As a result, the water supply valves 46a and 46b are turned on for 80 minutes, during which the water sprinklers 45a and 45b spray water into the tanks 41a and 41b, and the bag filling device B
Is forcibly stopped. On the other hand, ice making devices A1 and A
2 is step 3 in FIG. 5 in response to the signal indicating the abnormality.
It is determined to be "YES" at 04, and the execution of the program is stopped at step 308. As a result, the ice making devices A1, A
The operation of 2 is also forcibly stopped. As described above, when an abnormality occurs in the bagging device B and the falling of the bagging ice is not completed within a predetermined time after the device B starts the bagging of ice, the ice making devices A1 and A2 perform ice And the bagging of the ice by the bagging device B are stopped. Further, in this case, since the ice remaining in the tanks 41a and 41b is melted and discharged, it is possible to prevent the ices from solidifying in the tanks 41a and 41b.

In the above-mentioned embodiments and modified examples, specific numerical values have been illustrated with respect to the operating time and capacity of each mechanism, but these times depend on the capacity and performance of each part adopted in each mechanism. It is variously changed according to it.
