Is opened and closed, and the source 2 exhaust valve relay 92BR is turned on.
When turned off, the source 2 exhaust valve 92B is opened and closed.
Further, when the source 3 air supply valve relay 88CR is turned on and off, the source 3 air supply valve 88C is opened and closed, and when the source 3 exhaust valve relay 92CR is turned on and off, the source 3 exhaust valve 92C is opened and closed. Is done.

The operation of the frozen dessert production apparatus 1 of the present invention having the above-described configuration will be described. The hopper 6 stores a liquid soft cream mix. Then, as described above, this liquid soft cream mix is introduced into the cooling cylinder 8 and cooled while being stirred by the beater 7 to produce a semi-cured soft cream. When extracting a soft ice cream that does not top the sauce, the rightmost lever is pulled down to move the plunger 12D upward, and the plunger 12D is separated from the through hole 18 of the take-out nozzle 4B as described above. The rightmost outlet of the extraction path 14 is also opened. Further, since the soft cream extraction switch 44D is turned on via the arm 42D by the rise of the plunger 12D, the control device C drives the beater motor 9 to rotate the beater 7.

As a result, the semi-cured soft ice cream in the cooling cylinder 8 is pushed forward, enters the extraction passage 11D from the extraction passage 14, and is extracted through the through hole 18 of the extraction nozzle 4B. In this way, soft ice cream (frozen dessert) that is not topped by sauce pumping,
The extraction nozzle 4 passes through the extraction passage 11D located on the rightmost side.
B.

Next, the operation of the source pressurizing device 2 of the frozen dessert production device 1 will be described with reference to the control sequence diagram of FIG. In the following description, the case where the source is extracted from the closed container 53A will be described.
The same applies to 53C.

(1) Normal Operation (Preparation) Assuming that the source container 54 is housed in the closed container 53A and the lid member 57 is closed as described above, the source 1 lid switch 66A is in the ON state. . In this state, the source 1 switch 96 on the operation panel 22 is pressed (O
N) and the control device C is an air compressor ON relay 5
1CR and the source 1 air supply valve relay 88AR are turned ON, the air compressor 51 is operated, and the source 1 air supply valve 8 is turned on.
Open 8A. In addition, always the source 1 exhaust valve relay 92AR
Is turned off and the source 1 exhaust valve 92A is closed. Further, the source valve 36 corresponding to the plunger 12A is also lowered to close the introduction passage 24.

Thus, the compressed air discharged from the air compressor 51 is supplied into the closed vessel 53A via the discharge pipe 86, the check valve 87, the source 1 supply valve 88A, the branch pipe 89A, and the supply pipe 67, The air pressure in the closed container 53A (indicated by the source 1 pressure (Mpa) in FIG. 9) increases. At this time, the control device C blinks the red and green chips of the source 1 LED 101 of the operation panel 22 and blinks in orange to indicate that the source container 54 (source 1) in the closed container 53A is being prepared for extraction. Display to the user.

When the pressure in the sealed container 53A rises to a set value, for example, 0.2 Mpa, the control device C
Determines that the air pressure in the sealed container 53A has increased to a set value based on the output of the source 1 pressure sensor 93A, and determines that the air compressor ON relay 51CR and the source 1
The air supply valve relay 88AR is turned off, the air compressor 51 is stopped, and the source 1 air supply valve 88A is closed.
At this point, the preparation for extracting the source from the source container 54 of the closed container 53A is completed, and the control device C sets the source 1 LED1
01 is switched to orange continuous lighting to indicate to the user that the source can be extracted.

When the volume of the source container 54 is reduced by the following source extracting operation, the air pressure in the closed container 53A is reduced (see FIG. 9). Then, the air pressure in the sealed container 53A is 0.18 Mpa (hysteresis 0.02 Mpa), which is the lower limit lower than the set value (0.2 Mpa).
If the air compressor is turned on again, the control device C turns on the air compressor again based on the output of the source 1 pressure sensor 93A.
Turn on relay 51CR and source 1 air supply valve relay 88AR
Then, while operating the air compressor 51, the source 1
The air supply valve 88A is opened. When the air pressure in the sealed container 53A rises to the set value, the air compressor O
N relay 51CR and source 1 air supply valve relay 88AR are turned on.
FF is performed, the air compressor 51 is stopped, and the source 1 air supply valve 88A is closed. Thereby, the control device C
Means that the air pressure in the sealed container 53A is always set to 0.
The air pressure applied to the source container 54 is controlled to a set value while maintaining a (substantially) constant value in the range of 2 Mpa to 0.18 Mpa.

(2) Normal operation (extraction) When the plunger 12A is moved upward by pulling down the leftmost lever 13A, the plunger 12A is separated from the through hole 31 of the star-shaped adapter 19 as described above, and the extraction is performed. The leftmost exit of road 14 is also open. Further, since the soft cream extraction switch 44A and the source 1 take-out switch 46A are turned on via the arm 42A when the plunger 12A is raised, the control device C drives the beater motor 9 to rotate the beater 7.

As a result, the semi-cured soft ice cream in the cooling cylinder 8 is pushed forward, enters the extraction passage 11A from the extraction path 14, and passes through the through hole 31 of the leftmost star-shaped adapter 19 of the extraction nozzle 4A. Is extracted.

On the other hand, since the connection arm 38 of the leftmost source valve 36 is engaged with the engagement groove 39 of the plunger 12A, the source valve 36 moves up with the elevation of the plunger 12A. When the source valve 36 rises, the introduction passage 24 is opened as described above. Therefore, the source passage 54 in the closed container 53A and the leftmost introduction passage 24 of the discharge nozzle 4A are connected via the hose 16A and the source extraction port member 59.
Is communicated.

As a result, the source container 54 housed in the closed container 53A is pressed by the air pressure in the closed container 53A, and the source is extracted from the opening at the rear end of the source extraction port member 59 and the communication holes 83 on the side surfaces. It is extruded into the mouth member 59 and enters the discharge nozzle 4A through the hose 16A. The source that has entered the take-out nozzle 4A reaches the annular passage 23 from the leftmost introduction passage 24, is diverted right and left there, and is discharged from the outlets 32,32.

As a result, the source is continuously added to the periphery along the flow of the soft cream extracted from the take-out passage 11A through the through-hole 31 of the star-shaped adapter 19, so that the source is extracted. A unique sauce pattern is formed on the surface of the soft ice cream, which increases the willingness to purchase and allows customers to enjoy the unique flavor of strawberry jam from the beginning to the end of eating.

When the extraction is completed, the lever 13A is pushed up to lower the plunger 12A. As a result, the plunger 12A closes the leftmost outlet of the extraction path 14 and comes into close contact with the through hole 31 of the star-shaped adapter 19, so that the extraction of the soft serve is stopped. Further, the soft cream extraction switch 44A and the source 1 takeout switch 46A are also turned off via the arm 42A, so that the control device C stops the beater motor 9. In addition, since the source valve 36 is also lowered with the plunger 12A being lowered, the leftmost introduction passage 24 in the discharge nozzle 4A is closed, thereby stopping the addition of the source. Further, since the source valve 36 closes the introduction passage 24, leakage of the source from the outlet 32 is also prevented.

(3) Normal Operation (Adjustment of Source Amount) The amount of the source extracted from each of the closed containers 53A to 53C (the amount of the source extracted in one extraction of the soft ice cream, or the source per a certain time) To adjust the amount of extraction, the setting switch 94 on the operation panel 22 is pressed. When the setting switch 94 is pressed, the control device C first turns on the source 1 LED 101 in green,
It indicates that the source amount is being adjusted (Source 2
The LED 102 and the source 3 LED 103 are turned off), and the current setting value corresponding to the source (source 1) of the source container 54 in the closed container 53A is indicated by the number of lit LEDs by the source amount setting display 106.

For example, assuming that the source amount in the case of the air pressure in the closed container 53A having the set value of 0.2 Mpa is a standard value, the standard value is, for example, the source amount setting display 1
This is displayed by turning on three LEDs 06 from the left. Then, for example, to increase the source amount, pressing the right arrow button of the source amount adjustment switch 99 causes LE
The lighting of D increases by one. Then, the set value of the air pressure in the sealed container 53A is increased by one step (for example, a predetermined pressure such as 0.04 Mpa). Thereby, the source container 5
Since the air pressure applied to 4 increases, the pressing force increases and the amount of extraction increases. Conversely, if it is desired to reduce the source amount, pressing the left arrow button of the source amount adjustment switch 99 reduces the lighting of the LED by one. Then, the set value of the air pressure in the closed container 53A is lowered by one step. As a result, the air pressure applied to the source container 54 is reduced, so that the pressing force is also weakened and the amount of extraction is reduced (the same hysteresis is used). Thus, the set value of the air pressure in the closed container 53A can be set to an arbitrary value within a certain range.

If the setting switch 94 is pressed twice, the control device C turns on the source 2 LED 102 in green (the source 1 LED 101 and the source 3 LED 103 are turned off).
The current setting value corresponding to the source (source 2) of the source container 54 in the closed container 53B is displayed by the number of lighted LEDs by the source amount setting display 106. Then, similarly, the source amount can be adjusted by the source amount adjustment switch 99. When the setting switch 94 is pressed three times, the control device C turns on the source 3 LED 103 in green (source 1L).
The ED 101 and the source 2 LED 102 are turned off), and the current setting value corresponding to the source (source 3) of the source container 54 in the closed container 53C is displayed by the number of lit LEDs by the source amount setting display 106. Then, similarly, the source amount can be adjusted by the source amount adjustment switch 99.

(4) Normal Operation (Lid Open) Here, during such normal operation, for example, the closed container 53A
When the stopper 58 is rotated counterclockwise, that is, when the lid member 57 of the closed container 53A is about to be opened, the projection 72 of the stopper 58 is separated from the arm 65 of the source 1 lid switch 66A, and the switch is turned off. The contact 66A is opened (OFF). When the source 1 lid switch 66A is turned off, the control device C sets the source 1 exhaust valve relay 9
2AR is turned on to open the source 1 exhaust valve 92A. Also, the source 1 LED 101 is blinked in red,
The user is notified of the opening of the exhaust valve 92A, and the operation of the air compressor 51 and the opening of the source 1 supply valve 88A are prohibited.

As a result, the inside of the closed vessel 53A is communicated with the outside via the exhaust pipe 91A and the source 1 exhaust valve 92A, so that the compressed air in the closed vessel 53A is removed and the air pressure quickly drops to the atmospheric pressure. . Therefore, the inconvenience that the lid member 57 pops out due to the air pressure in the closed container 53A when the stopper 58 is removed is eliminated. When the stopper 58 is rotated clockwise again and the stopper 1 lid switch 66A is turned on, the control device C starts the above-described extraction preparation operation again and starts the closed container 53A.
The internal air pressure is raised to a set value.

(5) Normal Operation (Sold Out) The source in the source container 54 is gradually reduced by the extraction of the source accompanying the removal of the soft ice cream (chilled dessert). When the source in the source container 54 runs out, the volume of the source container 54 does not decrease any more. Therefore, the plunger 12A is pulled down, the source valve 36 is raised, and even if the source 1 extraction switch 46A is turned ON, the hermetic sealing is performed. The air pressure in the container 53A does not decrease (changes).

The control device C, based on the output of the source 1 pressure sensor 93A, turns on the source 1 take-out switch 46A, and if there is no change in the air pressure in the closed vessel 53A for a certain period of time, or When the pressure change amount is smaller than a certain value (threshold value), the sealed container 53A
It is determined that the source (source 1) in the source container 54 is finished, that is, sold out.

When the control device C determines that the sold-out condition has occurred, it turns on the source 1 exhaust valve relay 92AR and turns on the source 1
The exhaust valve 92A is opened, and the air in the sealed container 53A is discharged as described above to bring the pressure to atmospheric pressure. And the sauce 1L
The end of the source is notified to the user by blinking the ED 101 in red. As described above, since the end of the sauce is determined according to the pressure change in the closed container 53A, it is not necessary to attach a special sensor or switch for detecting the sold-out condition or to count the number of sold products.

Here, when the amount of the source in the source container 54 decreases, the bottom surface of the source container 54 comes into contact with the rear end opening of the source extraction port member 59 as shown by a broken line in FIG. Resulting in. However, the rear end of the expanded portion 82 of the source extraction port member 59 enters the depth of the source container 54 beyond the neck portion 54A and protrudes inward.
3 is located further inward of the source container 54 than the neck 54A, so that the bottom surface of the source container 54 is
Even if the rear end opening 9 is closed, the communication hole 83 on the side surface is not closed, and a space in the source container 54 is secured around it.

As a result, the source container 54 is further crushed, and the bottom surface comes into close contact with the base of the neck portion 54A from the state shown by the broken line in FIG. 6, and the source in the source container 54 is pushed out until the communication hole 83 is closed. Therefore, the amount of the source remaining in the source container 54 at the time of the determination of the sold out can be minimized. Therefore, it is possible to reduce costs by effectively using the source.

(6) Source Replacement Operation When the source in the source container 54 of the closed container 53A is completed as described above, the completed source container 54 is replaced with a new source container 54. In that case,
First, the stopper 58 of the sealed container 53A is rotated counterclockwise to remove it from the holders 61 and 62. As a result, the projection 72 of the stopper 58 is separated from the arm 65 of the source 1 lid switch 66A, and the contact of the source 1 lid switch 66A is opened (OFF). The control device C determines that the lid member 57 has been opened by turning off the lid switch 66A. Next, the user presses the source 1 switch 96.

When the source 1 switch 96 is pressed with the source 1 lid switch 66A turned off, the control device C turns on the air compressor ON relay 51CR and the source 1 air supply valve relay 88AR for, for example, 3 seconds. The air compressor 51 is operated for only 3 seconds, and the source 1 air supply valve 88A is opened. Thereby, air pressure is instantaneously applied to the source container 54 in the closed container 53A, and the lid member 57 is
And the source container 54 are pushed out to the opening side, so that the lid member 57
In addition, the source container 54 can be easily taken out. Also, by blinking the source 1 LED 101 in red during this time, it is displayed (notified) to the user that the pressure is being increased for replacement (during replacement). The user pulls out the pushed-out lid member 57 and the source container 54 from the closed container 53A to open the opening.

Thereafter, the control device C turns on the source 1 exhaust valve relay 92AR to open the source 1 exhaust valve 92A, exhausts the air in the sealed container 53A, and simultaneously releases the air in the sealed container 53A.
A new source container 54 is communicated between inside and outside of
Easy insertion into 3A. Also, the source 1 LED 101
Blinks green to indicate (notify) to the user that the replacement is in progress and the source 1 exhaust valve 92A is open. The control device C turns off the source 1 exhaust valve relay 92AR when the lid member 57 is closed (the source 1 lid switch 66A is ON) or 15 minutes after the source 1 exhaust valve 92A is opened, and the source 1 Exhaust valve 92A
Close.

Thereafter, the source extraction member 5 is made in the same manner as described above.
9 is inserted into a new source container 54 and attached to the lid member 57 by screwing, so that the source container 54 is closed.
3A, and the opening is closed by the cover member 57. Then, the stopper 58 is rotated clockwise to engage with the holders 61 and 62 (the source 1 lid switch 66A is
N) to complete the exchange. Thereafter, if the source 1 switch 96 is pressed, the control device C prepares for extraction via pressurization as described above.

(7) Abnormal operation display Here, during pressurization during the normal operation and the source replacement operation as described above, the air pressure in the closed vessel 53A becomes abnormally high based on the output of the source 1 pressure sensor 93A. In the case where it does not increase to the set value, it is determined that an abnormality has occurred in each valve of the source pumping device 2 or the air compressor 51 and so on. Alerts the operator that an abnormality has occurred and prompts a quick inspection. At the same time, the source 1 exhaust valve relay 92AR is turned on to turn on the source 1
The exhaust valve 92A is opened, and the air pressure in the sealed container 53A is set to the atmospheric pressure.

The control device C includes pressure sensors 93B and 93C.
In accordance with the operation of the lever 13B and the like, the same preparation, extraction, lid opening, sold out, source replacement, and operation abnormality display control as described above are similarly performed for the closed containers 53B and 53C. In this case, the supply pipes 88A to 88C and the exhaust valves 92A to 92C are respectively connected to the branch pipes 89A to 89C.
C is provided, and pressure sensors 93A to 93C are provided in the sealed containers 53A to 53C, respectively, so that the pressure in each sealed container does not affect other sealed containers, and the check valve 87 is also provided. Since it is provided, there is no backflow to the air compressor 51 side, and although the compressed air is supplied from the single air compressor 51 to the three closed containers 53A to 53C, the inside of each closed container 53A to 53C is The air pressure is independently controlled by the control device C,
The supply of the source is also performed independently for each of the extraction passages 11B and 11C.

The LEDs 101 to 1 on the operation panel 22
03 is composed of multi-color light-emitting LEDs, and the operating state of the source pumping device 2 is indicated by the lighting color and the continuous lighting / flashing, so that it is not necessary to provide an LED corresponding to each operating state. The state can be easily recognized, and the number of parts can be reduced. In particular, this is effective when a plurality of closed containers 53A to 53C are provided and a source is extracted from a plurality of source containers 54 as in the embodiment.

In this embodiment, three closed containers 53A to 53A-5
Although 3C is provided to allow topping of three kinds of sauces, two or four or more closed containers may be provided.
However, in that case, two or four or more take-out passages are provided. In the embodiment, the source extraction port member 59 is used.
A communication hole 83 is provided on the side surface of the rear end portion. However, the present invention is not limited to this. A cutout is formed at the rear end of the source extraction member 59 so that the rear end opening is not completely closed by the source container 54. It may be.

In the embodiment, each of the closed containers 53A to 53A
Although the air pressure in C is configured to be maintained at the set value, the present invention is not limited to this. Whenever the source is taken out with the rise of the plunger, compressed air is supplied from the air compressor into the closed container to set the value ( (Changeable) can be included. However, according to the configuration as in the embodiment, the responsiveness of the source pressure feeding to the removal of the frozen dessert is improved.

As described above, the source pressure feeding device 2 is provided with the air compressor 51 and the sealed containers 53A to 53B accommodating the source container 54 in an exchangeable manner, and the air compressor 51 reduces the air pressure in the sealed containers 53A to 53C. Since the source is raised and the source is pressure-fed by applying air pressure to the source container 54, the air source 51 can apply air pressure to the entire source container 54 in the closed containers 53A to 53C to push out the internal source. . Thus, as long as the source container can be deformed by air pressure, the source can be smoothly pumped and topped without being limited to its shape. In addition, the mechanical structure can be simplified and the maintainability can be improved as compared with a device that applies a mechanical pressing force or a device that applies a pressure to the source container via another fluid medium such as water. Therefore, significant cost reduction can be achieved. Also, since air pressure is applied to the source container 54 in the closed containers 53A to 53C, the source can be smoothly extruded.

In particular, the sealed containers 53A to 53C are provided with an opening for inserting the source container 54 and a lid member 57 for sealing the opening, and the lid member 57 is formed in the source container 54. Since the screw groove 77 into which the screw portion 54C is detachably screwed is formed, the screw groove 77 of the lid member 57 is formed.
The source container 54 can be detachably attached to the lid member 57 by screwing the screw portion 54C of the source container 54 to the cover member 57. As a result, the source container 54 is
7 and closed containers 53A to 53C from the opening.
And the opening can be sealed by the lid member 57 at the same time, so that the attachment and replacement of the source container 54 can be performed extremely easily.

The lid member 57 has the source extraction port member 5.
9 is attached, and the threaded portion 54C of the source container 54 is screwed into the thread groove 77 of the lid member 57.
4, the outlet 54A is air-tightly connected to the source extraction port member 59, so that the airtight connection between the source container 54 and the source extraction port member 59 is established by screwing the source container 54 to the lid member 57. At the same time, this can be achieved, and the workability of attaching the source container 54 to the closed containers 53A to 53C is further improved.

The screw portion 54C is formed around the outside of the outlet 54A of the source container 54, and the screw portion 54C
Is screwed into the screw groove 77 of the lid member 57, the source extraction member 59 enters the outlet 54A of the source container 54, and presses the screw portion 54C toward the screw groove 77 side. The screwing of the source container 54 to the source container 59 also achieves a seal between the source container 54 and the lid member 57, and the mounting workability of the source container 54 is further improved.

Further, the lid member 57 and the source extraction port member 59
Can be disassembled, so that the cleaning operation of the lid member 57 and the sauce extraction port member 59 is facilitated, and the sanitary maintenance property particularly required in selling frozen desserts is also remarkably improved.

As a result, it becomes possible to apply air pressure to the entire source container in the closed container by the air compression device to push out the internal source.

Thus, as long as the source container can be deformed by air pressure, the source can be smoothly pumped and topped regardless of its shape. In addition, the mechanical structure can be simplified and the maintainability can be improved as compared with a device that applies a mechanical pressing force or a device that applies a pressure to the source container via another fluid medium such as water. Therefore, significant cost reduction can be achieved. In addition, since air pressure is applied to the source container in the closed container, the source can be smoothly extruded.

In particular, the closed container has an opening for inserting the source container, and a lid member for closing the opening, and the lid member has a screw portion formed in the source container. Since the screw groove that can be detachably screwed is formed,
The source container can be detachably attached to the lid member by screwing the thread portion of the source container into the screw groove of the lid member.

Thus, the source container can be inserted into the closed container through the opening with the source container attached to the lid member, and at the same time, the opening can be sealed with the lid member. It can be easily done.

According to the second aspect of the present invention, in addition to the above, the lid member is provided with a source extraction port member, and the screw portion of the source container is screwed into the screw groove of the lid member.
Since the outlet of the source container is air-tightly connected to the source extraction port member, the airtight connection between the source container and the source extraction port member is achieved simultaneously with the screw attachment of the source container to the lid member. And the workability of attaching the source container to the closed container is further improved.

According to the third aspect of the present invention, in addition to the above, the screw portion is formed around the outside of the outlet of the source container, and the screw portion is screwed into the screw groove of the lid member.

Seal is also achieved,
The mounting workability of the source container is further improved.

According to the fourth aspect of the present invention, in addition to the above, the lid member and the sauce extraction port member can be disassembled, so that the cleaning work of each member becomes easy, which is particularly required in the sale of frozen desserts.
