Description

  The present invention relates to an apparatus for quantitatively supplying dry ice pellets. Specifically, in a supermarket or the like, a certain amount of dry ice pellets to be used as a coolant when taking refrigerated foods or frozen foods from a storage container is reliably ensured. The present invention relates to a manual dry ice pellet dispensing apparatus that can be taken out.

  Dry ice pellets, called pellet-shaped dry ice or granular dry ice, are chalk-shaped dry ice having a diameter of about 6 mm and a length of about 5 to 50 mm, and have a mass that is smaller than that of thin or block-shaped dry ice. It is used as a coolant when taking refrigerated foods and frozen foods in supermarkets and other stores because it has a large surface area and can cool food to be cooled relatively quickly and is easy to handle. However, in that case, from the viewpoint of reducing the cost by suppressing unnecessary consumption of dry ice and ensuring safety, a fixed amount supply device equipped with a weighing bowl is used to register a certain amount of dry ice pellets. I put it in a bag.

  For example, as a dry ice pellet quantitative supply device, a hopper (storage container) that contains dry ice pellets, a vibration basket that is disposed substantially horizontally at the lower end outlet of the hopper and mounted on an electromagnetic vibration device, and the vibration A cylindrical pellet supply rod disposed below one end of the rod, a weighing rod disposed below the pellet supply rod and reciprocating horizontally by a linear motor and rack and pinion, and movement of the measurement rod An apparatus is disclosed which is mainly composed of a shooter (discharge port) provided at the end, and in which dry ice pellets dropped into a pellet supply basket are accommodated in a measuring basket and discharged into the shooter. (See Patent Document 1).

  Also, as other dry ice pellet quantitative supply devices, a bottomed cylindrical granular dry ice container having a discharge hole in the bottom, and a rotary metering disposed in the inner bottom of the granular dry ice container A flat-bottomed shallow dish-shaped housing with a granular dry ice outlet opening at the bottom. A top plate in which the upper surface of the housing is sealed and the granular dry ice inlet port is opened at a position different from the granular dry ice outlet port of the housing, and a measuring bowl (granular dry ice measuring hole) in a part thereof And a disk-shaped housing housed in the housing, and the granular dry ice is collected while rotating the housing of the rotary weighing device by the drive motor. The apparatus of the turntable structure which is adapted granular dry ice to accommodate the metering chambers of Masutai taken into the container taken out this parts is disclosed (see Patent Document 2).

  By the way, dry ice pellets are a cooling material for cooling foods, etc., which are commodities, and in stores such as supermarkets, the area occupied by the quantitative supply device is reduced, and the labor and cost required for maintenance and management of the device are reduced. Reduction is demanded.

  Therefore, as for the above-mentioned quantitative supply device for dry ice pellets, a simpler manual type device that is compact and does not use mechanical driving force is also desired. However, in the case of designing a so-called manual type quantitative supply device using a measuring rod having a structure that is moved manually, the following problems actually occur. In other words, when dry ice pellets are dropped from the lower end of a storage container such as a hopper into a weighing bowl, the dry ice pellets are filled from the storage container to the weighing bowl, but the weighing bowl is moved in that state. Because the dry ice pellets are sandwiched between the upper edge of the rear side of the weighing basket and the edge of the storage container's drop port (the edge corresponding to the front side of the weighing bowl in the moving direction). , It becomes difficult to move the weighing scale smoothly.

  In the case of an apparatus using a mechanical driving force, the dry ice pellets sandwiched between the members are crushed by the driving force, so the above problems hardly occur, but the dry ice pellets have a considerable hardness. Therefore, in the manual type apparatus, there is a situation that it becomes impossible to operate even with slight biting of the dry ice pellets.

  The present invention has been made in view of the above circumstances, and an object of the present invention is a manual dry ice pellet quantitative supply device that is more compact and easy to maintain. An object of the present invention is to provide a dry ice pellet quantitative supply device that can reliably take out a fixed amount.

  In order to solve the above-mentioned problems, in the present invention, a movable table that is horizontally moved by manual operation is disposed below a storage container for storing dry ice pellets, and a cylindrical weighing rod having upper and lower ends opened is movable. A fixed amount of dry ice pellets in the storage container is taken out by moving the weighing bowl from the drop port at the lower end of the storage container to the extraction port of the dry ice pellet extraction member by operating the movable table. I made it. Then, a guide piece that protrudes to the inside of the measuring rod and bends downward with respect to the upper end edge of the measuring rod corresponding to the rear side in the moving direction when the measuring rod is moved from the drop port of the storage container to the discharge port of the take-out member. When the dry table is filled with dry ice pellets directly from the storage container directly under the storage container drop opening, the movable table is operated to move the measurement container to the discharge port of the take-out member. The dry ice pellet above the upper end of the weighing tub is pushed up to the storage container side with the guide piece, and at the same time, a part of the dry ice pellet below the upper end of the weighing tub is made to flow around to the lower side of the guide piece, This sorts the dry ice pellets at the top of the weighing bowl up and down and prevents the dry ice pellets from being caught between the top edge of the weighing bowl and the edge of the storage container's drop opening. Was Unishi.

  That is, the gist of the present invention is a dry ice pellet quantitative supply device for storing dry ice pellets and taking out a certain amount of dry ice pellets by manual operation, containing the dry ice pellets and having a drop opening at the lower end. Between the storage container and the take-out member, and a take-out member for taking out the dry ice pellets that is disposed below the storage container and has a take-out port at a position different from the drop port of the storage container. And a movable table provided with a cylindrical measuring rod whose upper and lower ends are opened, and the movable table is manually operated so that the measuring rod extends over the drop port of the storage container and the discharge port of the take-out member. It is configured to move horizontally, and at the upper edge of the weighing bowl, there is a transfer when the weighing bowl is moved from the storage container drop port to the discharge port of the extraction member. At a position corresponding to the direction rearward side resides the guide piece bent to and downwardly projecting into the interior of the metering chambers are attached to dispensing device dry ice pellets, wherein.

  According to the dry ice pellet quantitative supply device according to the present invention, the specific shape is formed at the upper edge of the measuring bowl corresponding to the rear side in the movement direction when the measuring bowl is moved from the drop port of the storage container to the discharge port of the take-out member. The guide piece is attached and when the dry ice pellets are taken out by operating the movable table, the dry ice pellets at the upper end of the weighing basket can be sorted up and down by the guide pieces, so that the upper edge of the weighing bowl is stored The dry ice pellets are not sandwiched between the edges of the container drop opening, the movable table can be operated smoothly, and a certain amount of dry ice pellets can be reliably removed from the storage container.

  An embodiment of a quantitative supply device for dry ice pellets according to the present invention will be described with reference to the drawings. In the following description, the dry ice pellet quantitative supply device is abbreviated as “quantitative supply device”, and the dry ice pellet is abbreviated as “pellet”.

  The quantitative supply device of the present invention is a device for storing pellets and taking out a certain amount of pellets by manual operation when necessary, and is assembled to a frame 5 as a frame constituting the outer shell as shown in FIG. It is mainly composed of a storage container 1, an extraction member 2 for extracting pellets, and a movable table 3.

The storage container 1 is a hopper-shaped container for storing a predetermined amount of pellets, and a dropping port 11 formed in, for example, a rectangular tube shape is provided at the lower end thereof. The storage container 1 is configured such that the outer peripheral portion is covered with a heat insulating material and the upper end portion can be opened and closed with a lid (not shown). The internal volume of the storage container 1 can be appropriately designed according to the consumption of pellets, but is usually set to about 10 to 100 liters. Further, the horizontal cross-sectional area of the drop port 11 at the lower end is set to about 10 to 80 cm ² , substantially the same as the cross-sectional area of the take-out port 21 of the take-out member 2 and the cross-sectional area of the measuring rod 31 of the movable table 3 described later. Yes.

  The take-out member 2 is a member constituting a discharge port for taking out the weighed pellets at a predetermined position, and is a pair of frames that are horizontally spanned as a part of the frame 5 at a substantially middle portion of the height of the frame. It is arranged below the drop opening 11 of the storage container 1 using the gantry 51. As shown in FIG. 2, the take-out member 2 has a drop hole 20 having a substantially square horizontal cross section on one end side (right side in FIG. 2) of a flat plate that is a base material. A rectangular cylindrical outlet 21 that functions as a discharge shooter is provided concentrically with the drop hole 20.

  The take-out port 21 of the take-out member 2 seals the lower end opening of the measuring rod at the upper surface of the take-out member 2 at a position where the later-described measuring rod 31 does not overlap, so that the drop port 11 of the storage container 1 is used. It is provided at a position different from that in other words, that is, at a position away from the dropping port 11 at least by the inner method of the measuring rod 31. In addition, as shown in FIG. 2, in order to accurately guide the lower end of the weighing rod 31 when operating the movable table 3 described later, the lower surface of the weighing rod 31 is loosely fitted on the upper surface of the extraction member 2. A recessed portion 23 is formed.

  The movable table 3 is a member that constitutes a cage of the moving structure and seals the dropping port 11 of the storage container 1. As shown in FIGS. 1 and 2, the movable table 3 is disposed between the storage container 1 and the movable table 3. Is arranged. As shown in FIGS. 3A and 3B, the movable table 3 is formed on a table substrate 34 having a substantially rectangular planar shape, and is laminated on the lower surface of the table substrate and is slightly wider than the table substrate. And a sliding plate 35.

  At least the table substrate 34 of the movable table 3 is made of a resin having excellent low-temperature characteristics, such as fluororesin and high-density polyethylene, in order to prevent sticking to the dropping port 11 of the storage container 1 due to freezing of moisture in the air. Yes. On one end side of the movable table 3 (on the right side in FIGS. 3A and 3B), a substantially square drop hole 30 having substantially the same horizontal cross section as the drop port 11 of the storage container 1 is opened. On the lower surface of 3, a square cylindrical measuring rod 31 having upper and lower ends opened is provided concentrically with the drop hole 30.

  On the other hand, as shown in FIG. 1B, each of the pair of pedestal portions 51 spanned between substantially the middle portions of the frame 5 has guide rails 53 each having a groove on the side surface. Are mounted along the length of the gantry. As shown in FIG. 3A, both edges in the width direction of the sliding plate 35 of the movable table 3 (upper and lower edges in FIG. 3A) are outside the table substrate 34. The protruding portion is engaged with the groove of each guide rail 53. That is, as shown in FIG. 2, the movable table 3 is configured to be movable so that the measuring basket 31 moves horizontally across the dropping port 11 of the storage container 1 and the extraction port 21 of the extraction member 2 by manual operation. ing.

  A handle 36 for operating the movable table is provided at one end in the length direction of the movable table 3 (the right end in FIGS. 3A and 3B). Further, in order to relatively guide the lower end of the drop port 11 of the storage container 1 when operating the movable table 3, the engraved portion in which the lower end of the drop port 11 is loosely fitted on the upper surface of the movable table 3. 33 is formed.

  In the quantitative supply device of the present invention, when the measuring bowl 31 of the movable table 3 is moved, the pellets housed in the upper part of the measuring bowl 31, in other words, the pellets located at the lower end of the dropping port 11 of the storage container 1. Is not sandwiched between the lower end of the drop port 11 and the upper end of the measuring rod 31, as shown in FIG. 3, the upper edge of the measuring rod 31, that is, the edge of the dropping hole 30, is made of steel or stainless steel. A strip-shaped guide piece 4 is attached.

  The guide piece 4 moves rearward in the moving direction when moving the measuring rod 31 from the dropping port 11 of the storage container 1 to the extracting port 21 of the extracting member 2 with respect to the upper end of the measuring rod 31, that is, the periphery of the dropping hole 30. (The left side of the substantially square drop hole 30 in FIG. 3 (a)), and the guide piece 4 protrudes to the inside of the measuring rod 31 and bends downward. It is configured. Thereby, when the measuring table 31 is moved by operating the movable table 3, the pellets on the upper side of the measuring table 31 can be sorted vertically.

  By the way, as described above, the pellet has a choke shape having a diameter of about 6 mm, a length of about 5 to 50 mm, and in many cases a length of about 5 to 20 mm. Therefore, in order to secure the escape allowance of the pellets selected downward when sorting the upper pellets of the weighing basket 31, the guide piece 4 has a protruding length (protrusion) toward the drop hole 30 when viewed from above. Length) is set to 5 to 10 mm. Further, as shown in FIGS. 3B and 3C, the rear edge of the drop hole 30 of the table substrate 34 and the sliding plate 35 (the drop of the storage container 1) with respect to the upper end of the measuring rod 31. The structure in which the edge on the rear side in the moving direction when moving the measuring rod 31 from the mouth 11 to the taking-out port 21 of the taking-out member 2 protrudes by about 5 to 10 mm, in other words, the above-mentioned rear side wall of the measuring rod 31 The portion is configured to recede from the drop hole 30.

  That is, as shown in FIG. 3 (c), in the preferred embodiment of the present invention, in the movable table 3, the guide piece 4 is attached to the upper end edge of the measuring rod 31 and the edge of the drop hole 30 is projected. Thus, the total overhang length L, which combines the overhang length of the guide piece 4 and the overhang length of the edge of the drop hole 30, is set to 10 to 20 mm.

  The reason for setting the total overhang length L in such a range is as follows. That is, when the total overhang length L is less than 25 mm, when the pellets are sorted up and down by the guide pieces 4, the flowability (escape) of the pellets in the measuring rod 31 is small, and the load on the guide pieces 4 is increased. However, a force is required by operating the movable table 3. On the other hand, when the total overhanging length L exceeds 40 mm, when the pellets fall through the dropping port 11 of the storage container 1, a large amount of pellets go down to the lower part of the overhanging portion, so that the measuring rod 31 is enlarged. The effect of increasing the fluidity of the pellets in the measuring basket 31 when sorting by the guide piece 4 is small.

  As described above, in the present invention, by attaching the guide piece 4 to the upper end edge of the measuring bowl 31, when the measuring bowl 31 is moved, a part of the pellets sorted into the measuring bowl 31 is guided to the guide piece 4. It can be made to flow so as to be detoured to the lower side, and the function of sorting the pellets up and down by the guide pieces 4 can be further enhanced. Note that the lowering margin at the tip of the guide piece 4 is normally set to 10 mm or less. In the present invention, the shape of the guide piece 4 that is bent downward is only required that the tip of the guide piece 4 is directed downward from the base end, and is a shape that is curved when the guide piece 4 is viewed from the side. There may be.

  In the quantitative supply device of the present invention, for example, when pellets are used for cooling food, the movable table 3 is reciprocated to take out a certain amount of pellets. In that case, first, the handle 36 of the movable table 3 is grasped, and the movable table 3 is pushed backward, that is, from the right side to the left side in FIG. As a result, as shown in FIG. 4A, the measuring basket 31 is positioned immediately below the dropping port 11 of the storage container 1, and the pellets in the storage container 1 are dropped from the dropping port 11 onto the measuring bowl 31. Next, the movable table 3 is pulled forward, that is, from the left side to the right side in FIG. As a result, as shown in FIG. 4C, the measuring basket 31 can be positioned immediately above the extraction port 21 of the extraction member 2, and the pellet in the measurement basket 31 can be taken out from the extraction port 21.

  In the present invention, as shown in FIG. 1 (b), when the measuring basket 31 is moved from the drop port 11 at the lower end of the storage container 1 to the takeout port 21 of the takeout member 2 by operating the movable table 3, Since the guide piece 4 is attached to the upper end edge of the measuring rod 31 corresponding to the side and projects to the inside of the measuring rod 31 and bends downward, the guide piece 4 moves the pellet above the measuring rod 31 up and down. Can be sorted.

  That is, when the measuring table 31 is moved by operating the movable table 3 in a state where the pellet is filled from the inside of the storage container 1 to the measuring basket 31 while being located directly below the dropping port 11 of the storage container 1, the guide The piece 4 pushes up the pellet above the upper end of the measuring tub 31 to the storage container 1 side, and at the same time, causes a part of the pellet below the upper end of the measuring tub 31 to flow to the lower side of the guide piece 4, As a result, the pellets at the top of the weighing basket 31 are sorted into the upper and lower sides. Therefore, in the constant supply device of the present invention, the dry ice pellets may be sandwiched and bitten between the upper end edge on the rear side in the moving direction of the measuring bowl 31 and the edge portion of the drop port 11 of the storage container 1. The movable table 3 can be operated smoothly, and a certain amount of pellets can be reliably taken out from the storage container 1.

  In the present invention, the drop hole 30 of the movable table 3 is not limited to a quadrangle, but can be designed to be other polygons or circles. In that case, the guide piece 4 has an upper end portion corresponding to the rear side in the moving direction when the measuring rod 31 is moved from the dropping port 11 of the storage container 1 to the taking-out port 21 of the taking-out member 2, that is, a dropping hole. It suffices if it is arranged over the length of about 1/3 to 1/2 of the entire length with respect to 30 peripheral edges. Furthermore, in the present invention, the movable table 3 is not limited to the table that reciprocates as illustrated in the figure, but may be a turntable that is manually rotated.
