Description

  The present invention relates to a quantitative take-out apparatus for taking out a certain amount of granular dry ice.

  When frozen foods, ice confectionery, cakes, etc. are purchased at general retail stores, supermarkets, department stores, etc., they are usually handed with dry ice as a cold insulation material. Recently, granular dry ice such as cylindrical pellets has come to be used frequently because of the convenience that the required amount can be easily obtained and there are advantages in terms of safety and handling.

  In addition to such convenience, it has many advantages such as being able to store a considerable amount at once and hygienically, reducing loss due to sublimation, being economical and having sufficient weighing control. Therefore, this type of quantitative take-out device that can take out granular dry ice with a simple operation and accurate weighing tends to be used in relatively large-scale stores such as supermarkets and department stores (for example, (See Patent Document 1).

Hereinafter, a conventional quantitative dry ice takeout device will be described with reference to FIG.
The stirring tool 6 is rotatably arranged in the granular dry ice storage chamber 1 having a heat insulating structure, and a dry ice outlet 5 is opened in a part of the bottom wall of the granular dry ice storage chamber 1. A rotary weighing device 7 in which a gutter member 9 is rotatably accommodated is disposed inside, and an opening having a size corresponding to the dry ice outlet 5 is vertically penetrated on the upper surface plate of the rotary weighing device 7. The dry ice discharge port 14 is formed at a phase position different from the position where the dry ice outlet port 5 is formed on the bottom plate of the rotary weighing device 7, and the granular ice corresponding to the dry ice discharge port 14 is formed. This is a quantitative dry ice take-out device in which an ice take-out container 16 is disposed so as to be able to be withdrawn / retracted, and the stirrer 6 and the bowl member 9 are configured to be able to rotate synchronously.

  The conventional granular dry ice taking-out apparatus shown in FIG. 5 allows the granular dry ice to be taken out as described below. In a state where granular dry ice is filled and accommodated in the granular dry ice storage chamber 1, the granular dry ice flows down into the measuring space when the measuring space formed in the rotary saddle member 9 matches the dry ice outlet 5. Then, a certain amount of granular dry ice is accommodated, and by further rotation of the measuring space, the measuring space and the dry ice discharge port 14 coincide with each other, whereby the granular dry ice is taken out in a state of being measured in the measuring space volume. It becomes.

In this case, since the stirring tool 6 that rotates in synchronization with the rotation of the eaves member 9 is disposed in the granular dry ice storage chamber 1, the stirring tool 6 is placed in the granular dry ice storage chamber 1. Therefore, even if the granular dry ice causes a cross-linking phenomenon in the granular dry ice storage chamber 1, the cross-linking is broken by the rotating stirring tool 6.
Japanese Patent Laid-Open No. 2002-321778 (especially claims and FIG. 2)

  As is apparent from FIG. 5, the conventional quantitative dry ice take-out device described above substantially stores granular dry ice in the granular dry ice storage chamber 1 having a bottomed rectangular tube shape. The space is in the shape of a truncated conical quadrangular pyramid, and has a structure in which a fork-shaped stirring tool 6 is rotatably arranged. Due to the fact that a considerable volume of dead space is formed between the head quadrangular pyramid and the bottomed rectangular tube surrounding it, the shape of the casing body 2 is reduced due to a decrease in the granular dry ice capacity. Problems that do not fit in the compact can be considered.

  Further, the cross-sectional shape of the casing main body 2 that determines the outer shape of the apparatus main body is relatively large with respect to the cross-sectional shape of the rotary measuring device 7 arranged at the bottom narrowed to the bottom. For this reason, the dry ice take-out path 17 has to be arranged in an outwardly inclined manner, and a part of the granular dry ice flowing down from the dry ice discharge port 14 extends obliquely in the dry ice take-out path 17. There is a risk that it will remain in contact with the side wall and cause cross-linking, which may hinder smooth removal of dry ice to the dry ice take-out container 16.

  The present invention has been made paying attention to such problems, and its purpose is to increase the stirring effect under a compact structure and to prevent granular dry ice from being generated without causing a crosslinking phenomenon.

A granular dry ice outlet 18 having a smaller opening area than that of the granular dry ice discharge passage 12 is opened at a corresponding position on the same axis, and the granular dry ice inlet 17 and the granular are formed at a part near the periphery of the housing 14. A granular dry ice metering hole 19 having a size corresponding to the granular dry ice inlet 17 is provided at a position corresponding to the dry ice outlet 18 coaxially, and is directly below the granular dry ice container 2. The granular dry ice take-out container 7 is arranged at a position corresponding to the granular dry ice discharge path 12 so that it can be taken in and out from the front side. It is intended to provide a quantitative extraction apparatus particulate dry ice, wherein.

  In the present invention, the granular dry ice metering hole 19 formed in the rotated casing 14 matches the granular dry ice introduction port 17 in a state where a predetermined amount of granular dry ice is filled and accommodated in the granular dry ice container 2. At that time, the granular dry ice is introduced into the granular dry ice measuring hole 19 by flowing down, and a certain amount of granular dry ice is accommodated. By matching the granular dry ice outlet 18 and the granular dry ice discharge passage 12 immediately below the granular dry ice outlet 18, the granular dry ice is taken out by the granular dry ice metering hole 19 by a fixed amount.

  Further, since the agitator 6 that rotates in synchronization with the rotation of the housing 14 is provided at the bottom of the granular dry ice container 2, the position immediately before being introduced into the granular dry ice metering hole 19 As a result of the effective stirring of the granular dry ice layer present in the structure, even if a cross-linking phenomenon occurs, the cross-linking can be reliably broken by the rotating stirring blade 16.

  Furthermore, in the present invention, the granular dry ice remaining in the granular dry ice container 2 is obtained by synchronously rotating the agitator 6 and the casing 14 with the granular dry ice take-out container 7 taken out from a predetermined position.

Can be done.

  According to the present invention, the rotary weighing device is accommodated in the inner bottom portion of the granular dry ice storage portion formed in the heat insulating structure, and is synchronized with the casing rotating in the weighing device immediately above the rotary weighing device. Since the rotating stirrer is housed, the granular dry ice metering is a measuring space that penetrates the granular dry ice inside the granular dry ice storage part into the rotating housing while eliminating the cross-linking of the dry ice with the stirrer. As the granular dry ice measuring hole is further rotated, the granular dry ice in the measuring hole can be taken out from the granular dry ice discharge passage into the granular dry ice take-out container. This makes it possible to reliably and easily obtain a certain amount of granular dry ice at all times.

Further, a drive motor 8 is disposed at a central portion in the casing directly below the granular dry ice storage portion 2 with an output shaft vertically upward, and the rotation formed by coaxially connecting to the output shaft. By inserting and inserting the shaft 21 into the rotary measuring device 5 and the stirring tool 6, the shaft 21 is fitted to the housing 14 and the stirring blade 16 and is integrally coupled to the shaft.

  On the other hand, the opening area of the upper surface plate of the lower casing 4 provided below the granular dry ice container 2 is larger than that of the granular dry ice discharge passage 12 at a position located directly below the granular dry ice discharge passage 12. The granular dry ice recovery port 20 is coaxially opened. The granular dry ice recovery port 20 is used when collecting the granular dry ice remaining in the granular dry ice storage unit 2 at night after the end of the work. Under the state where the container 7 is taken out from a predetermined position, the stirring tool 6 and the casing 14 are synchronously rotated by the number of rotations determined according to the remaining amount, so that the remaining granular dry ice is collected into the granular dry ice recovery port. Through 20, the particles can be sequentially collected in a granular dry ice collection box 9 installed in the lower casing 4. In addition, the code | symbol 4A in FIG.1 and FIG.4 shows the opening / closing door hinged by the front of the lower casing 4. FIG.

With this structure, compared to a device whose entire surface is a flat surface, a curved surface part is partially formed and the effect on the design surface is exhibited, and the depth dimension is reduced and the device is compact. There is an advantage that can be put together.

  In FIG. 4, reference numeral 23 is an air damper spanned between the lid 11 and the upper side casing 3, 24 is a lid fastener for hermetically fixing the lid, 25 is an indicator lamp, and 26 is a coin. An insertion slot, 27 is a coin discharge lever, and 28 is a coin outlet.

  The usage procedure when the quantitative dry ice take-out device having the above configuration is installed in a supermarket will be described. A purchaser who has purchased a product that needs to be shipped with dry ice and settled it at the cash register and received a coin corresponding to the packaged product required will come to the place where the granular dry ice quantitative take-out device is installed and receive a coin. Is handed over to the clerk, the clerk who has received this coin performs the take-out operation. That is, the coin received after confirming that the granular dry ice take-out container 7 is mounted at a proper position and that the granular dry ice is present in the granular dry ice storage portion 2 with the indicator lamp 25 or the like. Is inserted into the coin insertion slot 26 and the drive motor 8 is driven by the number of revolutions corresponding to the number of coins to take out the required amount of granular dry ice from the granular dry ice storage portion 2 to the granular dry ice takeout container 7. The granular dry ice in the ice take-out container 7 is transferred to a synthetic resin bag provided to the product purchaser, and the quantitative take-out operation per time is completed.

  In this way, the quantitative take-out operation is performed many times, and the granular dry ice is replenished to the granular dry ice storage unit 2 several times as necessary. Since the replenishment amount of the granular dry ice is already known from the number of times the drive motor 8 is operated, the remaining amount of the granular dry ice in the granular dry ice container 2 is naturally known. Therefore, after taking out the granular dry ice take-out container 7 from a predetermined position, the drive motor 8 is driven by the number of revolutions corresponding to this known remaining amount, whereby the entire amount of the remaining dry dry ice is stored in the lower casing 4. The granular dry ice collection box 9 collects the granular dry ice container 2 to empty the granular dry ice storage unit 2, thus ending the day's work by the staff.
