Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry ice take-out device for taking out dry ice, such as granular dry ice, by a fixed amount.

When purchasing frozen foods, frozen desserts, cakes, etc., dry ice is handed to the purchaser as a cooling agent at small-scale stores such as general retail stores and large-scale stores such as supermarkets and department stores. As for dry ice, granular dry ice such as cylindrical pellets is often used because it is easy to obtain the required amount and is convenient from the viewpoint of safety and ease of handling.

Particularly large-scale stores among the stores described above use a dry ice take-out device capable of accurately weighing and taking out a predetermined amount of granular dry ice with a simple operation. This kind of dry ice take-out device can store a considerable amount of granular dry ice, is hygienic, is economical by reducing the loss due to sublimation of dry ice, can perform sufficient weighing control, and can store a certain amount of granular dry ice. To accurately take out dry ice with a simple operation.

Japanese Patent Laid-Open No. 2002-100001 discloses a device for taking out a fixed quantity of granular dry ice. This apparatus for taking out a fixed amount of granular dry ice has a granular dry ice container with a heat-insulating structure. When the position of the dry ice measuring hole of the rotary container rotates while the granular dry ice is stored in the granular dry ice storage part, a certain amount of granular dry ice enters the dry ice measuring hole and is stored. Then, by rotating the position of the dry ice measurement hole of the rotary cell, when the position of the dry ice measurement hole matches the position of the dry ice outlet, a certain amount of granules measured by the volume of the dry ice measurement hole is obtained. The dry ice is taken out from the granular dry ice container through the dry ice outlet.

However, in the above-described granular dry ice metering device, when the granular dry ice is accommodated in the granular dry ice storage section, water vapor enters the granular dry ice storage section together with air. At the store, during non-business hours, the dry ice granules are removed from the dry ice granules container so that no dry ice granules remain in the dry ice granules container. On the other hand, even after the granular dry ice is removed from the granular dry ice container, the temperature inside the granular dry ice container is lower than the ambient temperature, and the moisture remains in the granular dry ice container without evaporating. put away.

For this reason, after stopping the quantitative dry ice extraction device, when the granular dry ice quantitative extraction device is restarted during the next business hours, when the granular dry ice is put into the granular dry ice storage unit again, the granular dry ice Moisture remaining in the dry ice container may refreeze due to cooling by the granular dry ice. If the moisture refreezes, the cell will stick to the housing or the like and will not be able to rotate. As described above, there is room for improvement in the fixed amount of dry ice granules that may not be taken out when restarted after being stopped in the fixed quantity dispense device for dry ice granules described in Patent Document 1.

A certain amount of dry ice flows from the dry ice measuring hole 19, through the guide tube 23 and the dry ice outlet 18, through the through hole 10P of the dry ice container 10, and falls toward the middle section 2B. there is

As shown in FIG. 8, the middle section 2B has a container accommodating section 33, a drive motor 8, a speed reducer 8R, a hot air supply section 70, and a control section 100. As shown in FIG. The container accommodating portion 33 is made of a metal plate and provided below the partition plate 2Q. The container accommodating portion 33 has an accommodating space SP that can accommodate the above-described dry ice taking-out container 7 so that it can be put in and taken out. The container housing portion 33 has a body portion 34 forming a housing space SP, a dry ice supply guide portion 35 and a dry ice drop guide hole 36 . The accommodation space SP of the main body 34 has a size that allows the dry ice container 7 to be taken in and out in the horizontal direction and completely accommodated.

The dry ice supply guide portion 35 is formed between the upper portion of the main body portion 34 and the partition plate 2Q, and has a dry ice guide hole 37. As shown in FIG. The dry ice guide hole 37 is located at a position corresponding to the hole 2N of the partition plate 2Q. The dry ice fall guide hole 36 is formed in the lower part of the main body 34 and is positioned at the lower part facing the dry ice guide hole 37 . As a result, a certain amount of the measured dry ice passes from the dry ice measuring hole 19 through the guide tube 23 and the dry ice outlet 18 to the through hole 10P and the hole 2N of the dry ice container 10 and the dry ice guide hole 37. , and supplied into the dry ice take-out container 7 arranged in the main body 34 .

The drive motor 8 and the speed reducer 8R shown in FIG. 8 are mounted on a partition plate 90. As shown in FIG. The output shaft of the drive motor 8 is decelerated by the decelerator 8R.

Can be collected in bulk. Here, when the dry ice is to be collected, the dry ice taking-out container 7 is removed from the storage space SP and dropped from the rotary weighing unit 5 through the dry ice drop guide hole 36 of the main body 34. Dry ice is recovered in a dry ice recovery box 92 through a dry ice recovery port 91 . More specifically, the granular dry ice remaining in the dry ice container 10 and the crushed dry ice are removed from the dry ice measuring hole 19 by rotating the stirrer 6 and the rotating body 14 a predetermined number of times. through the guide tube 23 and the dry ice outlet 18, through the through hole 10P and the hole 2N of the dry ice container 10, the dry ice drop guide hole 36, and the dry ice recovery port 91 to the dry ice recovery box 92. Collected in batches.

(Usage example of the dry ice take-out device 1)
Next, an example of use of the above-described dry ice removing device 1 will be described.
<Dry ice supply mode>
A dry ice removing apparatus 1 shown in FIG. 1 is installed in small-scale stores such as general retail stores and large-scale stores such as supermarkets and department stores. In order to take out a fixed amount at a time, it operates in dry ice supply mode. In the dry ice supply mode, the dry ice extraction device 1 supplies the granular dry ice stored in the dry ice storage part 10 to the dry ice extraction container 7 in the storage space SP shown in FIG. 8 by a constant amount. As shown in FIG. 5, the dry ice take-out container 7 is housed in the container housing portion 33 in advance. It can be confirmed that granular dry ice is contained in the dry ice container 10 by turning on the indicator lamp 29 shown in FIG.

Therefore, when it is necessary for the purchaser to cool the purchased product using dry ice, the purchaser settles the account at the cash register and receives a medal (also referred to as a coin) corresponding to the product. When the purchaser hands over the medal to, for example, an attendant, the attendant inserts the medal into the medal insertion slot 30 shown in FIG. 2 to take out the granular dry ice.

The control unit 100 shown in FIG. 8 drives the drive motor 8 when medals are inserted, thereby rotating the output shaft 8P by, for example, 360 degrees or more. As a result, the granular dry ice in the dry ice container 10 is stirred by the stirrer 6 and sent to the rotary weighing unit 5 . A constant amount of the stirred dry ice is weighed by the rotary weighing unit 5 and then supplied to the dry ice take-out container 7 . The clerk takes out the dry ice take-out container 7 from the storage space SP, transfers a certain amount of dry ice in the dry ice take-out container 7 to, for example, an attached synthetic resin bag and hands it over to the purchaser.

As described above, a certain amount of dry ice is taken out many times, and granular dry ice is replenished in the dry ice container 10 as necessary. Then, when it comes to the time zone after the end of work, the dry ice take-out container 7 is taken out from the storage space SP, and the granular dry ice remaining in the dry ice storage part 10 is removed from the through hole 10P, the hole 2N, and the dry ice guide. Through the hole 37 and the dry ice drop guide hole 36 , the dry ice is recovered in the dry ice recovery box 92 through the dry ice recovery port 91 .

Here, the hot air supply unit 70 sends the warm air W obliquely upward to the rotary weighing unit 5 . The hot air supply unit 70 is arranged so as to avoid a drop path for dropping and discharging granular dry ice remaining in the dry ice storage unit 10 when the dry ice removing device 1 is stopped. Therefore, even if the hot air supply unit 70 is provided, it does not interfere with the operation of discharging the dry ice.

If granular dry ice remains in the dry ice storage unit 10, water vapor enters together with the air, and moisture adheres to the -78.5°C dry ice. During non-business hours, granular dry ice is removed so that it does not remain in the dry ice container 10, but moisture may remain in the dry ice container 10 without evaporating, causing condensation. In such a case, after stopping the dry ice removing device 1, when the dry ice removing device 1 is restarted at the next business hour, granular dry ice is newly put into the dry ice container 10. If the dry ice storage unit 10 is re-stored, the moisture remaining in the dry ice storage unit 10 may be refrozen due to cooling by the charged granular dry ice. If the moisture refreezes, the rotating body 14 and the stirrer 6 of the rotary weighing unit 5 may stick to the first member 15 and the second member 13 and become unable to rotate, making it impossible to reliably take out the dry ice. be.

<Dryer operation mode>
Therefore, the control unit 100 of the dry ice removing device 1 according to the present embodiment executes the dryer operation mode. When it is time outside business hours, the operator opens the lid 4 and removes the granular dry ice from the inside of the dry ice container 10. - 特許庁During non-business hours, the control unit 100 of the dry ice dispensing device 1 automatically switches to the dryer operating mode. In the dryer operation mode, when granular dry ice is newly accommodated in the dry ice container 10 again at the next business hour, the rotary weighing unit 5, the stirrer 6 and the dry ice container 10 are not frozen. Thus, the control unit 100 operates the hot air supply unit 70 to dry the insides of the rotary measuring unit 5, the stirrer 6, and the dry ice storage unit 10. As shown in FIG.

The operating conditions of the dryer operation mode are that the lid 4 is opened to open the dry ice container 10, and that the dry ice take-out container 7 is taken out from the container space SP of the container container 33. . The control unit 100 can detect that the lid 4 is open by an open signal 4T from the lid sensor 4S. Further, the controller 100 can detect that the dry ice take-out container 7 has been taken out from the storage space SP of the container storage part 33 by the container take-out signal 7T from the sensor 40 .

When the controller 100 acquires the opening signal 4T and the container take-out signal 7T from the lid sensor 4S, the controller 100 operates the heater 71 and the electric fan 72 of the hot air supply unit 70 to rotate the rotary weighing unit 5 and the stirrer 6. and warm air W is supplied to the inside of the dry ice container 10 . The warm air W is supplied to the rotating body 14 of the rotary measuring unit 5 and the stirring tool 6 through the dry ice drop guide hole 36, the dry ice guide hole 37, the through hole 10P, and the dry ice outlet 18. As a result, the rotating body 14, the stirrer 6, and the inside of the dry ice container 10 are heated.

The hot air supply unit 70 can send hot air of, for example, about 30° C. to 40° C. to the inside of the dry ice container 10 to promote drying in the dry ice container 10 . As a result, no moisture remains in the dry ice container 10 . By providing the hot air supply unit 70, the insides of the rotary measuring unit 5, the stirrer 6, and the dry ice storage unit 10 can be dried, and malfunctions and failures of the dry ice extraction device 1 due to condensation and freezing of moisture can be avoided. can. Therefore, even if granular dry ice is newly introduced into the dry ice storage unit 10 at the next business hour, no moisture remains, preventing the moisture from refreezing and preventing the rotating body of the rotary weighing unit 5 from refreezing. 14 and stirrer 6 can remain rotatable.

As a result, after the dry ice take-out device 1 is stopped during non-business hours, when the dry ice take-out device 1 is restarted during business hours, new granular dry ice is added to the dry ice. Even if they are housed in the housing part 10, the rotating body 14 of the rotary weighing part 5 and the stirrer 6 can be prevented from refreezing. Therefore, the rotary weighing unit 5 can reliably take out a certain amount of dry ice into the dry ice take-out container 7 . The hot air supply unit 70 is arranged at a position displaced from the positions of the dry ice guide hole 37 and the dry ice drop guide hole 36, which are the drop paths through which the dry ice granules fall, and extends in the vertical direction Z with respect to the main body 34. , the hot air supply unit 70 can reliably send the hot air W to the rotary measuring unit 5 to prevent the rotary measuring unit 5 from freezing. can.

By the way, during business hours, when the dry ice removing device 1 is not used for a certain period of time, the granular dry ice in the dry ice container 10 does not adhere to each other or form lumps. To do so, the control unit 100 drives the drive motor 8 to rotate the stirrer 6 by a predetermined angle. The case where the machine has not been used for a certain period of time is the time during which no medals have been inserted during business hours. As a result, the dry ice granules in the dry ice container 10 are stirred by the stirrer 6, so that the dry ice granules do not adhere to each other or form lumps. The control unit 100 is provided with a timer 101, and the timer 101 stores in advance an arbitrary fixed time. The arbitrary fixed time is, for example, about 30 minutes, but is not particularly limited.

At this time, the rotation angle of the stirrer 6 is, for example, about 120 degrees or more and 240 degrees or less. The control unit 100 rotates the drive motor 8 forward to rotate the stirrer 6 by a predetermined angle, and then reverses the drive motor 8 to return the stirrer 6 to the original position before rotation.

Further, the dry ice removing device 1 shown in FIG. 8 is preferably designed with the following characteristic features. That is, in order to further prevent moisture from remaining in the dry ice container 10, the inner wall 10N of the dry ice container 10 is moved toward the front panel 2P with respect to the vertical axis T of the dry ice take-out device 1. It is slanted by an angle R. Similarly, the rotary weighing unit 5 and the stirrer 6 arranged in the dry ice storage unit 10 are also inclined at a predetermined angle R toward the front panel 2P with respect to the vertical axis T of the dry ice take-out device 1. are provided. The predetermined angle R is, for example, approximately 0.5 degrees or more and 5 degrees or less.

Moreover, an inclined guide portion 10R is provided at the corner of the through hole 10P of the dry ice container 10 on the side of the front panel 2P. The slanted guide portion 10R is slanted toward the dry ice guide hole 37 of the dry ice supply guide portion 35 and connected to the upper end portion of the side wall 37C forming the dry ice guide hole 37 . The inclined guide portion 10R guides the moisture inside the dry ice storage portion 10 toward the dry ice supply guide portion 35 and discharges it.

As a result, the moisture remaining in the dry ice container 10 can be guided and flow along the inner bottom portion of the dry ice container 10 and the inclined guide portion 10R when the dry ice take-out device 1 is at rest. . Therefore, it is possible to suppress the moisture from remaining in the dry ice container 10, and to suppress the refreezing of the moisture when the dry ice take-out device 1 is restarted after being stopped.

According to the dry ice removing device 1 according to the present embodiment, the hot air supply unit 70 supplies hot air to the rotary weighing unit 5 to warm and dry the rotary weighing unit 5 to remove moisture. The insides of the rotary weighing unit 5 and the dry ice storage unit 10 can be warmed by hot air and dried so that no moisture remains. Therefore, even if the dry ice is put into the dry ice storage unit 10 and stored in the dry ice storage unit 10 when the dry ice extraction device 1 is restarted after being stopped, the water content does not refreeze and the rotary measuring unit 5 does not move. can be prevented. Therefore, after the dry ice dispensing device 1 is stopped during non-business hours, when the dry ice dispensing device 1 is restarted during the next business hours, the rotary weighing unit 5 has a constant amount of of dry ice can be reliably taken out into the dry ice take-out container 7.例文帳に追加

In addition, when the dry ice take-out device 1 is at rest, the electric fan 72 can send the heat generated by the heater 71 of the hot air supply unit 70 to the rotary measuring unit 5, so that the rotary measuring unit 5 is heated by moisture. You can definitely prevent freezing.

In addition, since the hot air supply unit 70 can send hot air obliquely upward to the rotary measuring unit 5, the hot air supply unit 70 can be used in the dry ice storage unit when the dry ice removing device 1 is stopped. It is arranged so as to avoid the route for dropping and discharging the dry ice remaining in 10 . Therefore, it is possible to prevent the hot air supply unit 70 from interfering with the operation of discharging the dry ice.

In addition, when the dry ice is not taken out and the stirrer 6 has not stirred the dry ice in the dry ice container 10 even after a certain period of time, the stirrer 6 does not move the dry ice in the dry ice container 10 . agitate. As a result, it is possible to prevent the dry ice from clumping in the dry ice container 10, so that the rotary weighing unit 5 can reliably take out a certain amount of dry ice.

Furthermore, when the lid 4 is open and the dry ice container 7 is removed from the container housing portion 33 , the hot air supply portion 70 supplies hot air to the rotary weighing portion 5 . Therefore, the insides of the rotary weighing unit 5 and the dry ice storage unit 10 can be warmed by the hot air and dried so that no moisture remains. Even if the dry ice is stored in the dry ice storage part 10, the water content is not refrozen and the rotation type measurement part 5 is prevented from becoming stuck, so that a fixed amount of dry ice can be taken out without fail.
