The box is constructed so that it can be freely opened and closed by arranging a fitting panel on the side. At this time, the storage case 1 of this example has a single or a plurality of similarly opening and closing doors and fitting panels below it. For example, a shelf or a desk provided with an open shelf without the shelf, in this example, with an open shelf 14 having a height of 1.5 m, a width and a depth of about 60 cm. is there. In this example, the frame 11 is made of stainless steel formed from a metal or synthetic resin frame, for example, a stainless steel frame. At this time, the frame 11 is placed on the back of the frame 11. A pair of upper and lower intermediate frame members 12 are installed between the positioned vertical frame members, and this is used as a support frame for the electric vertical movement means. The fitting panel is made of, for example, glass or resin, and part or all of the panel is transparent or translucent so that the inside of the storage case can be seen through.

  In this example, the storage case 1 stores and arranges the stepping motor 3 and the electric up-and-down moving means 2 together with the rotating plate 4 so as to be stored therein. 3 to the electric vertical movement means are prevented from projecting to the back surface of the storage case 1.

  The rotating plate 4 is made of an appropriate material such as metal, resin, wood, etc., for example, as a front circular thick disk, and protrudes toward the thick disk-shaped rotating plate 4 toward the front, In this example, a plurality of gelbell pipe holders 5 for holding four gelbell pipes 6 are fixed by fixing means such as bolts or welding, in this example. The gel bell tube 6 is held by the gel bell tube holder 5 so that the body portion 61 of the gel bell tube 6 is positioned on the outer peripheral side of the rotating plate 4 and the scale portion 62 is positioned on the center side. In addition, the arrangement of the Gelbell tube holder 5 with respect to the rotating plate 4 is performed on the one side radius portion of the center line passing through the rotation center of the rotating plate 4.

  The gel bell tube holder 5 of the present example is such that the arrow plate at the lower end of the scale portion 62 in the gel bell tube 6 is positioned at the center of the rotating plate at the top of the center line when the rotating plate is stationary. In this example, the gel bell tube holder 5 is provided with a block-shaped holder main body 51 that receives the gel bell tube 6 and a cover plate 52 that fixes the gel bell tube 6. The holder body 51 is composed of a large-diameter hole up to an intermediate depth for fitting and holding the body portion 61 of the gel bell tube 6 and a small-diameter hole at the tip end that passes through the scale portion 62 of the gel bell tube 6 downward. A number of receiving holes corresponding to the number of gel bell tubes 6 to be held, in this example, four receiving holes are arranged in parallel from the back side to the front side, and are arranged in parallel with a synthetic resin or metal block shape. As a thing. The cover plate 52 has a downward recess for receiving the rubber plug 63 that closes the openings of the four gel bell tubes 6 fitted in the receiving holes of the holder body 51, and a bolt 55 that presses the rubber plug 63 from above. And one end in the longitudinal direction is pivotally fixed to the rotating plate 4 or the holder body 51 by a hinge while the free end at the other end in the longitudinal direction is fixed to the holder body 51. Thus, for example, a synthetic resin or metal thick plate is used which can be opened and closed with respect to the holder main body 51 by being detachably fixed by a fixing tool 54 such as a bolt or a fastener metal fitting. Accordingly, the gel bell tube 6 is fitted and held in the holder main body 51, the cover plate 52 is rotated, and the bolt 55 screwed in the screw hole is rotated and fastened to fix the rubber plug 63 of the gel bell tube 6.

For example, the stepping motor 3 fixed to the slide plate 23 and the rotating plate 4 fixed to the slide plate 23 are moved up and down at a high speed to thereby repeat the gel bell tube of the rotating plate 4. A vertical vibration operation is imparted to the gel bell tube 6 held by the holder 5. The vertical movement of the slide plate 23 can be performed at the same time when the stepping motor 3 rotates, for example, or separately from the rotation of the stepping motor 3 when the stepping motor 3 is stopped. In other words, it is programmed to move up and down simultaneously with the rotation of the stepping motor 3.

  The vibration mixing apparatus A thus formed opens the opening / closing door 13 of the storage case 1 and stores as a sample a quantity of sulfuric acid, milk, and pure amyl alcohol, which are determined in advance by a ministerial ordinance concerning the component standards of milk and dairy products.

It is intended to be used to give vibration mixing action by vibration and vertical vibration, and by this, the rotating plate by the stepping motor 3 according to the program As a result of the forward / reverse rotation and vertical movement of the sample, the sample of the Gerber tube 6 can obtain the dissolution of milk in sulfuric acid equivalent to that obtained by hand shaking by a skilled worker. Therefore, the structure is as simple as possible and is easy to use. However, by using the Gerber tube vibration mixing apparatus A, it is possible to always obtain an accurate measurement result of milk fat, and to solve the trouble due to the variation in the measurement result of the Gelbell method. Further, the gel bell tube 6 is held on the holder body 51 of the gel bell tube holder 5 and is held in parallel stably and surely by the cover plate 52, so that the gel bell tube 6 can be swung or detached during rotational vibration and vertical vibration. This eliminates as much as possible the possibility of trouble during vibration mixing, and the gel bell holder 5 holding the gel bell tube 6 is stored in the storage case 1 together with the rotating plate 4 to which the gel bell tube 6 is fixed. Therefore, even in the unlikely event that the Gerber tube 6 is detached from the Gerber tube holder 5, a mixture of sulfuric acid and milk due to the breakage of the Gerber tube 6 may be scattered in the room. Can be reliably prevented.
