[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weighing apparatus using silica sand and a weighing method using the weighing apparatus.

[0002]

2. Description of the Related Art A typical platform scale device includes a platform on which an object to be weighed is placed, a column extending upward from an end of the platform, and a display attached to an upper end of the column. The platform is placed on the floor, and an object to be weighed is placed on the platform and its weight or number is measured. In particular, digital platform scales that are battery-operated and can be used without a power source and that display digitally are widely used.

[0003]

When the above-described platform weighing apparatus is used, for example, in a rice mill, it is affected by the stability of the floor surface, impact, wind, etc. Weighing was not stable and accurate. An object of the present invention is to provide a platform weighing apparatus and a weighing method using the same, in order to eliminate such an unstable factor at the time of conventional weighing.

[0004]

SUMMARY OF THE INVENTION A weighing apparatus according to the present invention has a bottom wall and side walls rising from the periphery of the bottom wall and surrounding the bottom wall, and the bottom wall is placed substantially horizontally. A box having an open top, silica sand laid over the bottom wall in the box at a substantially constant height so that the top surface thereof is substantially horizontal, and On the top surface, a flat plate placed substantially horizontally, and a platform having a platform on which the object to be weighed is placed, and a platform scale placed on the flat plate so that the platform is placed substantially horizontally. It is characterized by including. The weighing method of the present invention has a bottom wall, and a side wall rising from the periphery of the bottom wall and surrounding the bottom wall. A box having an open top is placed on a floor surface and the bottom wall is arranged substantially horizontally. Laying silica sand on the bottom wall in the box and adjusting the top surface of the laid silica sand to be substantially horizontal;
Placing a flat plate substantially horizontally on the top surface of the laid silica sand; and And weighing or weighing the object to be weighed on the platform of the platform thus placed.

FIG. 1 is a perspective view of a platform scale apparatus of the present invention, and FIG. 4 is a perspective view of the platform scale apparatus with a part cut away. As shown in FIGS. 1 and 2, the platform scale device of the present invention includes a bottom wall 10 and a bottom wall 10.
And a box 8 having a side wall 9 rising from the periphery of the box and surrounding all sides. The top of box 8 is open. Each of the boxes 8 is provided with a hook 9a on which a leveler 7 to be described later is hung and a height adjusting foot 11 which can adjust the height of the box 8 by rotating.

As shown in FIG. 4, silica sand 5 is laid at a substantially constant height on the bottom wall 10 in the box 8.

A flat plate 6 is placed on the top of the laid silica sand 5.
The platform scale 1 having the platform 3 on which the object to be weighed is placed is placed on the flat plate 6. The platform scale 1 further includes a display scale device 2 connected to the platform 3, and a height adjusting foot 4 provided on the bottom surface of the platform 3 and capable of adjusting the height of the platform 3 by rotating. Is provided.

The procedure for constructing the weighing apparatus of the present invention using the above-described components and the method of measuring the weight or the number of objects to be weighed using this weighing apparatus will be described below.

First, as shown in the perspective view of the box 8 in FIG. 2, the box 8 is placed on the floor 12 with the bottom wall 10 of the box 8 down. Then, the leveler 7 removed from the hook 9a is placed on the bottom wall 10, and the height adjusting feet 11 are rotated and set in the direction indicated by the arrow F1 so that the bottom wall 10 is substantially horizontal. .

Next, the silica sand 5 is placed on the bottom wall 10 in the box 8.
Is laid to a substantially constant height, and the top surface is flattened so as to be substantially horizontal. Then, the flat plate 6 is placed thereon, and while confirming using the leveling device 7, FIG. As shown, the height of the flat plate 6 is manually adjusted in the direction of the arrow F2,
The flat plate 6 is set so as to be substantially horizontal.

The flat plate 6 set as shown in FIG.
On the platform 3, the platform 3 of the platform scale 1 is placed, and as shown in FIG. 4, the level adjuster 4 is rotated in the direction of arrow F3 while the leveler 7 is placed on the platform 3 and confirmed. As a result, the platform 3 is set to be substantially horizontal. Then, the object to be weighed is placed on the platform 3 of the platform weighing device configured in such a state, and the weight or the number is weighed.

When not in use, the leveler 7 is hung on the hook 9a of the box 8 (see FIG. 1). If the scale device of the present invention has been used for a long period of time, there is a possibility that the silica sand 5 will be stiff. Therefore, it is preferable to use the leveler 7 to check and adjust the level of the platform 3 from time to time.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As the platform scale 1, for example, a digital platform scale of "KV series" manufactured by Kett Science Laboratory Co., Ltd. is used. The size of the bottom wall 10 of the box 8 is about 670 mm in length and about 450 mm in width, and the height of the side wall 9 is about 305 mm and the thickness is about 5 mm. The dimensions of the flat plate 6 are about 610 mm long, about 390 mm wide, and about 12 mm thick.
It is. The height of the silica sand 5 spread on the bottom wall 10 in the box 8 is about 70 mm. As the hook 9a, for example, a trade name "TL type ball-mounted western lamp suspension" manufactured by Sugatune Industry Co., Ltd. is used. As the leveler 7, for example, a product name “Handy Level 2” manufactured by Ebisu Corporation is used.

[0014]

According to the present invention, the spread silica sand 5 absorbs the impact, so that it is not affected by the stability of the floor surface or the impact by using a platform scale device in a rice mill or the like. Further, the scale 8 can stably and accurately measure the weight or the number of the objects to be weighed without being affected by the wind caused by the air conditioning in the factory by the box 8, and the conventional scale is measured. The unstable factor at the time can be eliminated. In addition, in the platform scale device of the present invention, the adjustment is extremely simple. In addition, when the present invention is used in a food factory or the like, the box 8 prevents splashing from the surroundings, so that measurement can be performed extremely hygienically.
