[産業上の利用分野]
本発明は、大秤量用と小秤量用の大小2台から成るはか
りを、外形的には単一の大ばかりとほぼ同一寸法の1台
にまとめ、大小様々な種類と量の物品の重量を、精度良

のである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a scale consisting of two large and small scales, one for large weighing and one for small weighing, into one scale having approximately the same external dimensions as a single large scale. The present invention relates to a composite scale that can accurately and efficiently measure the weight of articles of various sizes and quantities.
[従来の技lR]
産業上ではかりを使用する場合に、例えば500gの物
品重量Go、05gの精度で計量し、50kgの物品を
5gの精度で計る必要があり、測定の経済性や設置スペ
ースの節約などの関係から、重量が相当に異なる両計量
物を共に1台のはかりで測定したいという要望がある。[Conventional Techniques] When using a scale in industry, for example, it is necessary to weigh an article weighing 500 g with an accuracy of 0.5 g, and it is necessary to measure a 50 kg article with an accuracy of 5 g, which reduces the economic efficiency of measurement and the installation space. There is a desire to use one scale to measure both objects, which have considerably different weights, in order to save money.
しかしながら、フルスケール50kgのはかりを用いて
、例えば500gの物品を0.05gという高い精度で
測定することは実際には不可能に近い、はかり自体が理
想的に製作されていたと仮定しても、50kg用はかり
の計量皿表面積や計量機構重量が比較的大きいため、風
が計量皿に作用するとか、振動が床から計量機構に伝達
するだけで、たちまち0.05gを超える測定値変動を
生じ所望精度を得ることができない。However, it is practically impossible to measure, for example, a 500 g article with a high accuracy of 0.05 g using a full scale scale of 50 kg, even assuming that the scale itself is ideally manufactured. Since the surface area of the weighing pan and the weight of the weighing mechanism of a 50 kg scale are relatively large, the mere act of wind acting on the weighing pan or the transmission of vibration from the floor to the weighing mechanism can quickly cause measured value fluctuations of more than 0.05 g. Can't get accuracy.
このような事情により、従来では測定すべき物品重量の

ている。Due to these circumstances, conventionally two independent scales, one large and one small, have been used depending on the weight of the article to be measured. Other formats are shown in Figure 4 (a) and (b).
, (c), a composite scale is used in which two scales, one large and one small, each of which uses a single display, are housed in a single case. In this figure, 1 is a composite scale, 2 is a large weighing pan, 3 is a small weighing pan, 4 is a case, 5 is a panel, 6 is a display, 7 is a power switch, and 8 is a display switch. , is shown.
しかし、これらの従来技術による複合形はかりには次の

はかりlのケース4を十分大きくする必要があるため、
複合形はかり1の価格や重量が増えるばかりでなく、必
然的に設置面積が大きくなる。(1) Considering the total planar space of the composite scale 1, the area of the large weighing pan 2 becomes smaller due to the inclusion of a small scale, which makes it difficult to measure large quantities of objects with high bulk. On the contrary, in order to make the weighing pan 2 large enough, it is necessary to make the case 4 of the complex scale l large enough.
This not only increases the price and weight of the composite scale 1, but also inevitably increases the installation area.
(2)大ばかりを使用する際に、重量の大きい被計量物
やその容器を、小ばかり計量皿3に衝突や落下させるな
どして強度の弱い小ばかりを損傷することが多々ある。(2) When using a large scale, a heavy object to be weighed or its container may collide with or fall onto the small scale weighing pan 3, often damaging the weak scale.

In the case of Figure IJ4 (a), this is less of a concern, but it is inconvenient in practical use because it is necessary to reach all the way with the hand when using a small device.
(3)大、小はかりの計量皿2.3が近接しているため
、容器を用いて物品重量を測定する場合に、その容器が

が多い。(3) Because the weighing pans 2.3 of the large and small scales are close to each other, when measuring the weight of an item using a container, the container may come into contact with the weighing pan on the side that is not being used, causing measurement errors. There are many.

ある。When using a large scale, the small scale weighing pan 3 is fitted into the recess 12 of the large scale weighing pan 2, as shown in Fig. 2(a), and functions as one unit when purchased. The weighing pans 2.3 lie on the same plane. And slide mechanism 1
4 is lowered, the scale weighing pan 3 is completely separated from the scale weighing mechanism 13. In this way, the weight of any object placed on the large scale weighing pan 2, including the portion occupied by the small scale weighing pan 3, is transmitted to the large scale weighing mechanism 10, and the weight can be measured using the large scale. will be held. In this way, when using a large scale, the condition is essentially the same as a single scale without any small scale, and measurement errors may occur due to damage to the scale or interference with the scale. There is no risk of it happening.

きる。When using a small weighing pan, the small weighing pan 3 occupies a higher position than the large weighing pan 2, so even if a thick container is used to measure weight, the container will not weigh the large weighing pan. There is no risk of a measurement error occurring due to contact with the pan 2, and the small weighing pan 3 and the small weighing mechanism 13
The planar arrangement is not limited to the embodiment, and can be selected at any position as long as it does not interfere with the measuring mechanism 10.

るように作用している。Regarding the slide mechanism 14 that raises and lowers the small weighing pan 3, a wide variety of structures and operation methods can be considered, and one specific example is shown in FIGS. 3(a) and (b).
Corresponding to FIG. 2(a), a) shows a state in which the small weighing pan 3 and the large weighing pan 2 are in operation when the large scale is in use, and FIG. Corresponding to (b), the usage state of the small scale is shown. The load portion 16 of the small scale weighing mechanism 13 has a support shaft 17 in the vertical direction, and the slide mechanism 14 moves along this support shaft 17.
can slide freely up and down. Load section 1
6 has an overhang 18 on one side of the base, and a lever 20 is rotatably supported by a shaft 19 provided approximately in the center of the overhang 18. The bifurcated hook portion 21 at the tip of the lever 20 sandwiches the protrusion 22 on the left side of the lower end of the slide mechanism 14, and a tension spring 24 is attached between the hook portion 21 and the fixing pin 23, so that the hook portion 21 is always held. It acts to attract.

) is selected, the tension spring 24.29
It is clear that due to this action, the positions occupied by the slide mechanism 14 and others are fixed and will not move to an intermediate position between the two. That is, the switching lever 15 is in a state where it is pressed against either the lower stopper 30 or the upper stopper 31, and the hook portion 21 at the tip of the lever 20 pushes down the protrusion 22 to the lower end of the stroke of the slide mechanism 14, or the hook portion 21 is stopped from rising further by the upper end 32 of the projecting portion 18, the slide mechanism 14 is pushed up and stopped. Note that the hook portion 26 of the switching lever 15 comes into contact with the protrusion 27 of the slide mechanism 14 only during the switching operation, and as is clear from FIG. 3, when the scale is in use, the two are completely separated, and the switching mechanism The presence of this does not cause any measurement error.
このように、切換レバー15を手動で操作することによ
り、第3図(a)に示すように小ばかり計量皿3を小ば
かり計量機構13から切り離して。In this manner, by manually operating the switching lever 15, the small weighing pan 3 is separated from the small weighing mechanism 13 as shown in FIG. 3(a).

ることも極めて容易に実施できる。It is also possible to integrate both weighing pans 2゜3 with the large scale weighing pan 2 placed on the large scale weighing pan 2, or to raise the slide mechanism 14 as shown in FIG. It is very easy to raise the weighing pan 3 above the plane of the pan 2 to uncouple the two, and to connect the scale weighing mechanism 13 to the scale weighing mechanism 13.

イッチ33を併設すると1表示器が1個で済む上に使用
するはかりの選択が切換レバー15の単一操作で行える
ため実用価値が更に向上する。From an economical point of view, it is preferable to use a single display 6 for both large and small scales, as shown in FIG. 1, instead of providing dedicated displays for each scale. As shown in FIG. 3, if a switch 33 is provided that simultaneously switches the connection of the internal circuits related to the display 6 in conjunction with the operation of the switching lever 15 that raises and lowers the small weighing pan 3, one display can be reduced to one. Moreover, since the scale to be used can be selected by a single operation of the switching lever 15, the practical value is further improved.
なお実施例においては、切換レバー15の手動操作によ

が、大ばかりの使用による秤量値の大きさにより、自動
的に大ばかりと小ばかりの切換選択を行うようにするこ
ともできる。In the embodiment, switching between the large scale and the small scale is performed by manual operation of the switching lever 15, but the switching between the large scale and the small scale is automatically performed depending on the size of the weighing value due to the use of the large scale. A selection can also be made.

することになる。According to this embodiment, although there is only one scale in terms of external dimensions, in reality, two scales, large and small, can be used by switching at any time, so it is particularly effective in practical use when used as a counting scale. First, accurately measure the weight of the known decimal parts using a small scale, accurately calculate the average weight per part, and then calculate the total weight of the large number of parts, which far exceeds the capacity of the small scale. It is possible to measure the total number of parts more quickly and at the same time easily indicate the total number of parts with a high degree of accuracy that is impossible with a single scale. Furthermore, since it can be used both for measuring the weight of large quantities of goods and precisely measuring the weight of small quantities of goods, it will greatly contribute to improving the qualitative and quantitative performance of weighing management.
