Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a frozen confection supply device, and more particularly to temperature increase control of a packed frozen confection.
[0002]
[Prior art]
For example, in the frozen confection supply apparatus as disclosed in Patent Document 1, the frozen confectionery is poured out by loading the packed frozen confectionery into a cylinder and pressing it with a piston. In the distribution stage or in the storage state in the store freezer, the packed frozen dessert is usually kept at -25 ° C. or lower for the purpose of maintaining its quality. Therefore, prior to loading the frozen confection supply device into the cylinder, it is necessary to raise the temperature to an appropriate pouring temperature of, for example, about -12 ° C.
[0003]
[Patent Document 1]
Japanese Patent Laid-Open No. 2000-189063
Conventionally, the temperature rise of such a packed frozen dessert is performed by storing the packed frozen dessert in a refrigerator of a frozen dessert supply apparatus that is set in advance to a temperature of, for example, about −12 ° C. For example, in a store, the temperature of the frozen dessert supply device is stored in the refrigerator the night before the frozen dessert is dispensed, and the temperature starts to rise. It was being dispensed.
[0005]
[Problems to be solved by the invention]
However, there is a risk that a bag-packed frozen dessert that has not been heated up is loaded into the cylinder due to the change of workers or the difference in the storage position in the storage. Since the central portion of the frozen dessert that has not been heated to the proper temperature for dispensing is hard, the extraction of the frozen dessert stopped halfway and was forced to be replaced with a new packed frozen dessert. That is, due to an insufficient temperature rise, the frozen dessert is discarded while remaining in the bag, resulting in a decrease in yield, making it difficult to efficiently dispense frozen dessert.
[0006]
In addition, immediately after the low temperature bagging frozen dessert is stored in the refrigerator of the frozen dessert supply device, the bagging frozen dessert shows a rapid temperature rise due to the temperature difference between the temperature of the bagging frozen dessert and the temperature inside the refrigerator, but as time passes Since the temperature difference is reduced, the temperature rise of the frozen frozen dessert is gradually reduced. For this reason, it took a long time of, for example, 8 to 12 hours for the temperature of the frozen confectionery to be in a stable state with respect to the internal temperature. Therefore, it is difficult to efficiently dispense frozen confections, and additional sales at stores that cannot secure the temperature rise time for packed frozen confectionery or stores that have finished selling predetermined frozen confections in a short time can be handled. was difficult.
This invention was made in order to solve such a problem, and it aims at providing the frozen dessert supply apparatus which can pour out frozen dessert efficiently.
[0007]

When the cock 7 is closed, the spout switch 10 is turned off, the pump 11 is stopped, the valve body 8 is lowered, the cock pipe 9 is closed, and the extraction of the frozen dessert 19 is stopped.
[0011]
When all of the frozen dessert 19 has been dispensed, the pump 11 is driven in the reverse direction by the operation of a piston lowering button (not shown) of the operation panel 21, and as shown by the broken arrow, the brine 13 is discharged from the pressure chamber 15 of the cylinder 14. Is returned to the brine tank 12 and the piston 16 is lowered to the lowest position. In this state, the front door A of the freezer compartment 1 and the lid 22 of the cylinder 14 are opened, and the packed frozen dessert 17 is replaced.
[0012]
In the freezer compartment 1, a hanger 31 as shown in FIG. 2 is arranged to hold the bag-packed frozen dessert 17. The hanger 31 has a bracket 32 having one end fixed to the inner wall surface of the freezer compartment 1 and the other end protruding into the freezer compartment 1. At the other end of the bracket 32, a notch 33 for hooking the outlet 18 of the bag frozen dessert 17 is formed, and a bolt 34 serving as a rotating shaft by engaging with the outlet 18 of the bag frozen dessert 17. A lever 35 that rotates about is attached in the vicinity of the notch 33.
[0013]
As shown in FIG. 3, a hanger switch 36 is disposed in the vicinity of the lever 35 at the other end of the bracket 32, and the tip of a plunger 37 that can be moved back and forth of the hanger switch 36 is in contact with the lever 35. The lever 35 is urged in the direction of the notch 33 so as to be in the state of FIG.
Further, stoppers 38 and 39 that define both ends of the rotation range of the lever 35 are fixed to the bracket 32.
[0014]
As shown in FIG. 4, when the take-out port 18 of the packed frozen dessert 17 is hooked and held in the notch 33 of the bracket 32, the lever 35 is pushed by the take-out port 18 as shown in FIG. It rotates in the direction of 36, and the plunger 37 of the hanger switch 36 moves backward. As a result, the hanger switch 36 is turned on, and the presence of the frozen confection 17 can be detected.
[0015]
Further, as shown in FIG. 6, the frozen dessert supply apparatus is provided with a control circuit 41. A hanger switch 36 is connected to the control circuit 41, and a temperature rise timer 42 and a temperature rise end lamp 43 are further provided in the control circuit. 41. The temperature increase timer 42 is preset with a predetermined time T1 required to raise the temperature from the distribution temperature to the appropriate temperature for pouring by exposing the bag-packed frozen dessert 17 to the temperature in the freezer compartment 1. The temperature increase end lamp 43 is installed, for example, on the operation panel 21 so as to be visible to the operator.
[0016]
The hanger 31 constitutes the holding means of the present invention, the hanger switch 36 constitutes the detection switch, the control circuit 41 and the temperature rise timer 42 constitute the control means, and the temperature rise end lamp 43 constitutes the display means.
[0017]
Next, the temperature raising operation of the frozen confection 17 in the frozen confection supply apparatus according to the first embodiment will be described with reference to the flowchart of FIG. First, in step S1, the on / off state of the hanger switch 36 is confirmed. When the hanger switch 36 is turned on, the control circuit 41 determines that the bag-packed frozen dessert 17 is held on the bracket 32 of the hanger 31, and starts the temperature raising timer 42 in step S2.
When the predetermined time T1 has elapsed and the temperature increase timer 42 has expired in step S3, the process proceeds to step S4, and the control circuit 41 lights the temperature increase end lamp 43.
Thereby, the operator can recognize that the bag-packed frozen dessert 17 held on the hanger 31 has been heated to the appropriate temperature for pouring.
[0018]
Thereafter, when the temperature-packed frozen dessert 17 is removed from the bracket 32 of the hanger 31 in order to pour out the frozen dessert, the lever 35 returns to the state shown in FIG. 3 and the plunger 37 of the hanger switch 36 is extended. The switch 36 is turned off. Therefore, when the off state of the hanger switch 36 is confirmed in step S5, the process proceeds to step S6, and the temperature rise end lamp 43 is turned off by the control circuit 41.
[0019]
In this way, the temperature rise timer 42 secures the predetermined time T1 required for temperature rise, and the temperature rise end lamp 43 is turned on after the temperature rise is completed, so that the packaged frozen desserts 17 that have not been heated are removed from the cylinder 14. It is possible to prevent accidental loading into the inside.
A plurality of hangers 31 can also be installed in the freezer compartment 1. In this case, a plurality of temperature rise end lamps 43 respectively corresponding to the plurality of hangers 31 are provided, and the predetermined time T1 is measured from the time when the bag-packed frozen dessert 17 is held for each hanger 31, and the corresponding temperature rise is completed. It is desirable that the temperature raising end lamp 43 is lit. In this way, even if a plurality of bag-frozen confections 17 are accommodated in the freezer compartment 1, a bag 14 that has not been heated is mistaken for a bag-frozen confection 17 that has been heated. It is possible to prevent loading inside.
[0020]
Embodiment 2. FIG.
As with the apparatus of the first embodiment, the frozen dessert supply apparatus according to the second embodiment has the entire structure shown in FIG. 1 and the hanger 31 shown in FIGS. 2 and 3 in the freezer compartment 1. However, instead of the temperature increase timer 42 and the temperature increase end lamp 43, a temperature increase control timer 44 is connected to the control circuit 41 as shown in FIG. The temperature is raised from the normal time, and, for example, -5 ° C control operation is performed such that -5 ° C is the lower limit. The temperature increase control timer 44 has a predetermined time T2 required in order to increase the temperature from the distribution temperature to the appropriate temperature for pouring by exposing the packed frozen dessert 17 to the temperature in the freezer compartment 1 under the control operation of −5 ° C. Is set.
[0021]
In the control circuit 41, the piston lowering button 45 of the operation panel 21, the cylinder lower float switch 46 for detecting whether or not the piston 16 is located at the lowest position, and the front door A of the freezer compartment 1 are opened. The door opening / closing switch 47 is connected to each other.
[0022]
The temperature rising operation of the frozen confection 17 in the frozen confection supply device according to the second embodiment will be described with reference to the flowchart of FIG. First, when the operator turns on the piston lowering button 45 of the operation panel 21 in order to replace the bag frozen dessert 17, the pump 11 is driven and the brine 13 is returned from the pressure chamber 15 of the cylinder 14 to the brine tank 12. As a result, the piston 16 starts to descend.
In step S11, the control circuit 41 confirms that the frozen confection 17 is not held on the bracket 32 of the hanger 31 by the off state of the hanger switch 36. In step S12, the piston 16 is turned on by the off state of the cylinder lower float switch 46. When it is confirmed that the front door A has been opened due to the ON state of the door opening / closing switch 47 in step S13, it is confirmed that the hanger switch 36 is ON / OFF again in step S14. Then, it waits until a new bagging frozen dessert 17 is held on the bracket 32 of the hanger 31.
[0023]
When the hanger switch 36 is turned on in step S14, it is determined that a new bag-packed frozen dessert 17 is held in the bracket 32 of the hanger 31, and the temperature rise control timer 44 is started in step S15 and the control circuit is controlled in step S16. No. 41 performs a -5 ° C control operation in which the temperature in the freezer compartment 1 is higher than the normal -12 ° C, for example, -5 ° C is set as the lower limit value. This −5 ° C. control operation is continued until the temperature rise control timer 44 expires. When the predetermined time T2 has elapsed and the temperature raising control timer 44 has timed out in step S17, the process proceeds to step S18, where the control circuit 41 ends the -5 ° C control operation, and the temperature in the freezer compartment 1 is set to the normal -12 ° C. To -12 ° C control operation.
[0024]
If it is determined in step S11 that the frozen confection 17 is held on the bracket 32 of the hanger 31 by the on state of the hanger switch 36, and the front door A is not opened by the off state of the door opening / closing switch 47 in step S13. If it is determined, the process proceeds to step S18 without moving to the −5 ° C. control operation, and the normal −12 ° C. control operation is continued.
[0025]
If it is determined in step S14 that the frozen confection 17 is not held by the bracket 32 of the hanger 31 due to the hanger switch 36 being off, whether or not the front door A is closed by the door opening / closing switch 47 in step S19. Confirm. If the front door A is closed without holding the frozen dessert 17 in the bracket 32 of the hanger 31, the process proceeds from step S19 to step S18, and the control circuit 41 does not shift to the -5 ° C control operation, but the normal -12 ° C control operation. To continue. If the front door A remains open, the process returns to step S14. In this way, steps S14 and S19 are repeated until the bag-packed frozen dessert 17 is held on the bracket 32 of the hanger 31.
[0026]
Thus, by performing the -5 ° C. control operation in which the temperature in the freezer compartment 1 is set to −5 ° C., which is higher than the normal time, over the predetermined time T2 when the temperature of the bag frozen dessert 17 is raised, for example, FIG. As shown by the solid line, it is possible to complete the temperature increase in a short time. FIG. 10 is a graph showing the temperature of the packed frozen dessert 17 with respect to the elapsed time when the predetermined time T2 is set to 3 hours and switched from the normal -12 ° C. control operation to the -5 ° C. control operation. The temperature when the normal -12 ° C control operation is continued without shifting to the operation is shown.
[0027]
As in the first embodiment, a plurality of hangers 31 can be installed in the freezer compartment 1. In this case, when the hanger switches 36 of all the hangers 31 are turned off in step S11 of FIG. 9, the process proceeds to step S12. That is, if at least one hanger switch 36 is in the ON state, it is determined that the frozen confectionery 17 remains in the freezer compartment 1, and in order to maintain the quality of the frozen confectionery 17 -5 ° C. Continue normal -12 ° C control operation without shifting to control operation.
In step S14, if at least one hanger switch 36 is turned on, it is determined that the frozen confection 17 has been stored in the freezer compartment 1, and the process proceeds to step S15 and subsequent steps to shift to the -5 ° C control operation. .
[0028]
In addition, the temperature at the time of temperature rising of the bagging frozen dessert 17 is not restricted to -5 degreeC, If it sets higher than the temperature in the normal freezer compartment 1, shortening of temperature rising time is realizable. Can be appropriately selected according to the type of the frozen confectionery 17 and the necessity of shortening the heating time. Moreover, the temperature in the normal freezer compartment 1 is not restricted to -12 degreeC, What is necessary is just to set according to various conditions.
[0029]
【The invention's effect】
As described above, according to the first aspect, when the bag-packed frozen dessert is held by the holding means, a predetermined time required for the temperature rise is secured, and the temperature rise is terminated by the display means after the predetermined time has elapsed. Since the information is displayed, it is possible to prevent the bag-packed frozen dessert that has not been heated from being accidentally loaded into the cylinder. Accordingly, a decrease in yield due to discarding while leaving the frozen dessert in the bag due to insufficient temperature rise is avoided, and efficient dessert dispensing becomes possible.
Further, according to the second invention, when the frozen confectionery is held by the holding means, the inside of the refrigerator is raised to a predetermined temperature set higher than the normal temperature over a predetermined time. The temperature increase can be completed, and efficient frozen dessert can be dispensed.
