Abstract
Description
この発明は床に置いた物品等、特に中小の工場や会社等に置ける物品の在庫管理を経済的、効率的に重量で管理しようとする物である。 The present invention is intended to economically and efficiently manage the inventory management of articles placed on the floor, particularly articles placed in small and medium-sized factories or companies by weight.
従来は管理用の大きな広い棚を設けたり、床に積み上げて目視で在庫管理を行っていた。
又は物品にタグを用いてコンピューター管理や本発明と同様弾性体を用いた重量管理（登録実新案第３０３１００１や特開平１０−３８６６９）があった。In the past, large management shelves were provided, or they were stacked on the floor for visual inventory management.
Alternatively, there are computer management using tags for articles and weight management (Registered Model No. 3031001 and JP-A-10-38669) as in the present invention.
次のような欠点があった。
（イ）コンピューター管理が出来ない小規模の工場や会社では、あらゆる場所に物品が置かれ目視管理の為、常に人為的ミスがあり発注点及び安全在庫の管理がうまく出来ない。
（ロ）その為に緊急発注や物品切れがあり、経済性及び製品の出荷に影響が出る。
（ハ）物品の種類が多い時は広い空間や棚等の管理設備が必要で、目視管理に時間がかかり大変である。
（ニ）録実新案第３０３１００１と特開平１０−３８６６９について
１：最低貯蔵量を設定する位置によってヒンジーからのモーメントが違い、負荷端部にかかる荷重が変化する。よって不安定で誤動作が起こる。（登録実新案第３０３１００１）
２：最低貯蔵量がある時、負荷端部にかかる荷重と下からのバネの反力は平衡状態でなければならない。つまりある物品に対しては最低貯蔵量設定時に負荷端部にストッパーをもうけてもよいが最低貯蔵量が違う物に対してはそれに合う様に、その度バネの感度を変えなければならない。
更に最大重量時にバネには最大重量がかかりバネを押し下げる為、バネに必要以上の負荷がかかる。物品載置台が傾き安定しない。この為最低貯蔵量の設定にばらつきが起こり不安定である。（登録実新案第３０３１００１、特開平１０−３８６６９）
３：上限ストッパーが無い為、例えば物品が無い場合バネが上方に最大まで伸びる。又最低貯蔵量とそれより１ヶ取った時の重量の変化が大きい場合はスイッチの開閉接点の動き以上にバネが動き無駄であると同時に振動の原因にもなる。（登録実新案第３０３１００１、特開平１０−３８６６９）
４：本発明の様に重量検知装置を標準化してないので複数の組み合わせが簡単に出来ない。（登録実新案第３０３１００１、特開平１０−３８６６９）
５：荷重負荷板と物品載置台等の固定は磁石を使っていないので簡単に装着できない。（登録実新案第３０３１００１、特開平１０−３８６６９）
６：表示器とスイッチは有線による連結物であるが無線による物では無い。（登録実新案第３０３１００１、特開平１０−３８６６９）
本発明はこれらの欠点を除く為になされたものである。There were the following drawbacks.
(B) In small factories and companies where computer management is not possible, articles are placed everywhere, and visual management makes it difficult to manage order points and safety stocks.
(B) Because of this, there are urgent orders and out-of-stock items, which affects the economy and product shipment.
(C) When there are many types of articles, management facilities such as a large space and shelves are necessary, and visual management is time consuming and difficult.
(D) Recording model No. 3031001 and JP-A-10-38669 1: The moment from the hinge differs depending on the position where the minimum storage amount is set, and the load applied to the load end changes. Therefore, it is unstable and malfunctions. (Registration Model No. 3031001)
2: When there is a minimum storage amount, the load applied to the load end and the reaction force of the spring from below must be in equilibrium. That is, for some articles, a stopper may be provided at the load end when the minimum storage amount is set. However, the sensitivity of the spring must be changed each time so that an object with a different minimum storage amount is fitted.
Furthermore, since the maximum weight is applied to the spring at the maximum weight and the spring is pushed down, an excessive load is applied to the spring. The article mounting table is not tilted and stable. For this reason, the setting of the minimum storage amount varies and is unstable. (Registration Model No. 3031001, Japanese Patent Laid-Open No. 10-38669)
3: Since there is no upper limit stopper, for example, when there is no article, the spring extends upward to the maximum. In addition, if the minimum storage amount and the change in weight when taking one are large, the spring moves more than the movement of the switching contact of the switch, and at the same time it causes vibration. (Registration Model No. 3031001, Japanese Patent Laid-Open No. 10-38669)
4: Since the weight detection device is not standardized as in the present invention, a plurality of combinations cannot be easily made. (Registration Model No. 3031001, Japanese Patent Laid-Open No. 10-38669)
5: The load plate and the article mounting table cannot be easily mounted because no magnet is used. (Registration Model No. 3031001, Japanese Patent Laid-Open No. 10-38669)
6: The display and the switch are connected by wire, but not by wireless. (Registration Model No. 3031001, Japanese Patent Laid-Open No. 10-38669)
The present invention has been made to eliminate these drawbacks.

In the weight detection device, there is provided a lower limit stopper 8 for restricting the total weight when the total weight reaches a predetermined value.
2: An upper limit stopper 7 is provided for restricting the total weight when the total weight becomes a predetermined value or less.
3: A switch 10 that opens and closes to detect that the total weight has reached a predetermined value by the amount of displacement between the lower limit stopper 8 and the upper limit stopper 7 is provided.
4: The switch 10 is connected to the alarm device 15.
A weight detector characterized by being configured as described above.
The switch open / close signal may be at any location as long as the displacement generated by the lower limit stopper and the upper limit stopper can be used.
The switch opening / closing signal is turned ON or OFF when the total weight reaches a predetermined value, and the switch opening / closing signal is turned OFF or ON when the total weight falls below the predetermined value (the switch of the predetermined value is ON). The weight detection device is characterized in that a stopper for regulating the total weight can be adjusted and fixed at each position where the switch is turned off.
According to a third aspect of the present invention, the switch and the alarm device are connected wirelessly. The alarm device may be a display or a computer.
According to a fourth aspect of the present invention, a magnet is attached to the top plate or the bottom plate or both of the weight detection device, and the connection with the tray (FIG. 3) or the base (FIG. 3) is made through a magnet. is there.
According to a fifth aspect of the present invention, the weight detection device is classified and standardized according to a predetermined value.
According to the sixth aspect of the present invention, a combination of plastic and metal is used, and metal is used in a place where the weight is heavy, and it can withstand the load. By making it plastic, light weight, improved accuracy, shortened assembly time, and cost reduction can be achieved.
以上の様に構成されているので、請求項１のストッパーの効果を図１、２で説明する。図２（Ａ）は従来の重量検知装置。（Ｂ）は本発明の重量検知装置である。
例えば物品総重量が１０の中で所定値を５とすると、１０から徐々に物品を取って行き、弾性体にかかっている総重量が所定値５の時（以下便宜上、下限値と言う）にその総重量を止めるために下限ストッパーを上下調節しながら上板に当たる所で固定し、所定値５から１ヶ取った時（以下便宜上、上限値と言う）にそれ以上上がらない様に上限ストッパーを上板に当たる様に上下調節しながら仮に固定する。所定値５から４に移った時、例えば所定値５の時のスイッチはＯＦＦで、所定値から１ヶの物品を取った４の時スイッチがＯＮすれば良い。これらのストッパーの間隔はスイッチのＯＦＦ−ＯＮ間の最小値とする。スイッチに例えばマイクロスイッチを使用するとＯＮ、ＯＦＦの切り替え間隔が最大０．５ｍｍあれば十分であるから、ＯＦＦからＯＮに変わる点を上下限値の中間約０．５ｍｍ地点に設定して、前段階の上限ストッパーの仮固定を調節して下限ストッパーから１ｍｍ位の所で固定する。下限値にストッパーがあるので例えば総重量が２０でも、又衝撃荷重をかけてもストッパーで荷重を押さえるので弾性体には所定値の５の総重量がかかるだけである。この様にすると上板は受け皿と共に最大でも１ｍｍ動くだけである。全体にわずか１ｍｍだけ瞬時上下するだけで、これ以外は静止状態であるから、従来の振動や衝撃等による弾性体のばらつきや誤動作が無くなる。
又上下限ストッパーが無ければ最小限の動きが設定不可能になり、大きく動けば動くほど何処かの場所での摩擦や引っ掛かりが大きくなり、精度的に問題が発生する。本発明はこの様に上下動最小限の動きを保持し、弾性体に所定値以上の負荷をかけず、精度を上げるものである。
請求項２は請求項５と関連して請求項５記載の様に分類、標準化して物品全体の重量を複数で支えると１つの重量検知装置（弾性体）にかかる重量が分散され弾性体の感度を大きくする事が出来精度が向上する。
この様に複数使うことにより例えば総重量１００に対して４ヶの重量検知装置を使うと１ヶにかかる重量は２５であり更に各重量検知装置に２本の弾性体を使うと１２．５が１本の弾性体にかかる重量である。ここから下限値と上限値の間隔１ｍｍを取るのは弾性体の設計に対しても十分であり、下限値と上限値のストッパーが上下調節固定できるので同じ物の本発明重量検知装置を複数個使うことによって、実に幅広い重量に対してわずかな下限値と上限値の間隔を作り出す事が出来、高精度に対応できる。
請求項３は無線を使用しているので小規模工場等では敷地が狭いため、物品の置き場所が変則的である。よって従来の有線では使用できないところでも、バッテリー搭載のスイッチで無線通信を可能にして、警報装置つながる物である。例えばパレット上に図３に示すように本発明の重量検知装置を複数組み込んだものを使用すればホークリフトで何所に持って行っても良い。
請求項４は本発明の重量検知装置を実装する時に上部に重量を受ける受け皿（図３）又は底板にベース（図３）を固定する必要がる。これらは通常ネジ等で固定しなければならないが、本発明は重量は静止荷重で上からかかる事に注目し横ズレはほとんど無視できるから重量検知装置の上板や底板に磁石を装着し、受け皿やベースに磁石が吸着する金属を部分又は全体に使用することによって、重量検知装置を只置くだけで良く実装の際に生ずる位置あわせの問題を皆無にする。磁石はゴム磁石の様な薄い柔らかい物の方が横からの力に対しても十分な保持力を示す。
請求項５は本重量検知装置が上記請求項２で説明の通り幅広い重量に対応できるが、更に所定値別に分けて標準、規格化する事により、要求される所定値に対してどの重量検知装置を選べば良いか組み合わせを容易にして精度を上げるものである。
請求項６は図６に示すように本重量検知装置をプラスチックと金属で作ればプラスチックは高精度で負荷が余りかからない所、例えば、軸と軸受け、上板、底板。金属は負荷がかかる所、例えば上板、底板の補強。調節ネジ、下限及び上限ストッパー等に使用すれば軽量、高精度、組み込み時間短縮が図れる。Since it is comprised as mentioned above, the effect of the stopper of Claim 1 is demonstrated in FIG. FIG. 2A shows a conventional weight detection device. (B) is a weight detection apparatus of the present invention.
For example, if the total weight of the article is 10 and the predetermined value is 5, when the article is gradually taken from 10 and the total weight applied to the elastic body is the predetermined value 5 (hereinafter referred to as the lower limit for convenience). In order to stop the total weight, the lower limit stopper is fixed at the position where it touches the upper plate while adjusting the height, and when taking one from the predetermined value of 5 (hereinafter referred to as the upper limit for convenience), the upper limit stopper should not be raised any further. Temporarily fix while adjusting up and down to hit the top plate. When shifting from the predetermined value 5 to 4, for example, the switch at the predetermined value 5 is OFF, and the switch may be turned ON at 4 when one article is taken from the predetermined value. The distance between these stoppers is the minimum value between the OFF and ON states of the switch. For example, if a micro switch is used as the switch, it is sufficient if the switching interval between ON and OFF is 0.5 mm at the maximum. Adjust the temporary fixing of the upper limit stopper and fix it at about 1 mm from the lower limit stopper. Since there is a stopper at the lower limit value, for example, even if the total weight is 20, or even if an impact load is applied, the load is suppressed by the stopper, so only a total weight of 5 of a predetermined value is applied to the elastic body. In this way, the upper plate moves only 1 mm at the maximum with the tray. The entire body is moved up and down by only 1 mm instantaneously, and the rest is stationary, so there is no variation in the elastic body or malfunction due to conventional vibration or impact.
Also, if there is no upper / lower limit stopper, the minimum movement cannot be set, and the greater the movement, the greater the friction and catching at some place, causing a problem with accuracy. In this way, the present invention maintains minimum movement in the vertical direction and increases the accuracy without applying a load exceeding a predetermined value to the elastic body.
When claim 2 is classified and standardized as in claim 5 in relation to claim 5, and the weight of the entire article is supported by a plurality of weights, the weight applied to one weight detection device (elastic body) is dispersed, and the elastic body The sensitivity can be increased and the accuracy is improved.
By using a plurality of weight detectors in this way, for example, when four weight detectors are used for a total weight of 100, the weight per one is 25, and when two elastic bodies are used for each weight detector, 12.5 is obtained. This is the weight applied to one elastic body. It is sufficient for the design of the elastic body to take a distance of 1 mm between the lower limit value and the upper limit value from here, and since the stopper of the lower limit value and the upper limit value can be adjusted up and down, use a plurality of the same weight detection devices of the present invention. With this, it is possible to create a slight interval between the lower limit value and the upper limit value for a wide range of weights, and it is possible to cope with high accuracy.
Since the site of claim 3 is small in a small factory or the like because radio is used, the place where the article is placed is irregular. Therefore, even in places where the conventional cable cannot be used, wireless communication is possible with a battery-mounted switch, and the alarm device is connected. For example, as shown in FIG. 3 on a pallet, if a plurality of weight detectors according to the present invention are incorporated, it may be carried by a forklift at any location.
According to the fourth aspect of the present invention, it is necessary to fix the base (FIG. 3) to the saucer (FIG. 3) or the bottom plate receiving the weight at the top when the weight detection device of the present invention is mounted. These must normally be fixed with screws, etc. However, in the present invention, it is noted that the weight is applied from the top with a static load, and the lateral displacement can be almost ignored. In addition, by using a part or the whole of the metal to which the magnet is attracted to the base, it is only necessary to place a weight detection device, and the problem of alignment that occurs during mounting is eliminated. A thin soft material such as a rubber magnet exhibits a sufficient holding force against a lateral force.
According to claim 5, the weight detection device can cope with a wide range of weights as described in claim 2, and further, by separating the standard and standardization according to predetermined values, it is possible to determine which weight detection device with respect to the required predetermined value. It is easy to combine and increase accuracy.
In a sixth aspect of the present invention, as shown in FIG. 6, if the weight detection device is made of plastic and metal, the plastic is highly accurate and does not require much load, such as a shaft and a bearing, a top plate, and a bottom plate. Metals are used to reinforce places where load is applied, such as top and bottom plates. If used for adjusting screws, lower and upper limit stoppers, etc., light weight, high accuracy, and shortening of assembly time can be achieved.
図１は断面図を用いた本発明の簡略説明図である。
上板２は中央が凹型でその中央に底板３に固定された調整ネジＡが上板２に当たらない様に貫通してある。その調整ネジＡは上板２を挟んで上に上限ストッパー７と下に下限ストッパー８を入れてある。上板２の両端中央部に軸受け４が直角に固定してある。同様に軸受け４に当たる底板３に軸５が軸受け４の中をスムースに上下する様に固定してある。その軸受け４の外周には弾性体６が装着してある。又上板２と底板３の間にスイッチ１０がその接点を調節ネジＢ１１によって設定出来る様にしてある。このスイッチはバッテリー搭載の無線送信機内蔵である。又スイッチとバッテリー搭載の無線送信機は一体型で無く別置きでも良い。更に上板２の上面に磁石１２を装着する。同様に底板３の下面にも磁石１２を装着する。FIG. 1 is a simplified illustration of the present invention using a cross-sectional view.
The upper plate 2 has a concave shape in the center, and an adjustment screw A fixed to the bottom plate 3 passes through the center so that the upper plate 2 does not hit the upper plate 2. The adjustment screw A has an upper limit stopper 7 on the upper plate 2 and a lower limit stopper 8 on the lower side of the upper plate 2. Bearings 4 are fixed at right angles to the center of both ends of the upper plate 2. Similarly, the shaft 5 is fixed to the bottom plate 3 that contacts the bearing 4 so as to move up and down smoothly in the bearing 4. An elastic body 6 is mounted on the outer periphery of the bearing 4. Further, the switch 10 can be set between the top plate 2 and the bottom plate 3 by an adjusting screw B11. This switch has a built-in wireless transmitter with battery. In addition, the switch and the battery-equipped wireless transmitter are not integrated and may be installed separately. Further, a magnet 12 is mounted on the upper surface of the upper plate 2. Similarly, the magnet 12 is attached to the lower surface of the bottom plate 3.
「実施形態の効果」
以上の様に構成されているので、受け皿（図３参照）は上限と下限ストッパー間だけ、つまり所定値から重量が小さくなった時のみ一瞬動くだけであるから従来のように振動が無い。
弾性体は１ヶでも２ヶでも良いが、もう一方の軸受けにも装着して２ヶ使うことによって重量検知装置の感度を更に上げることが出来る。
弾性体の感度が決まっているので、たとえ上下限ストッパーの間隔設定が大まかでも、この間でスイッチが開閉すれば所定値から外れた付近で必ず信号が出る。物品の在庫管理に於いてはそんなに高精度な物は要求されないのでたとえこの様な状態でも十分である。
通常重量検知装置は複数使用し受け皿とベース（図３参照）に磁石で固定されている。こうする事によってスイッチのＯＮ−ＯＦＦ調整はスイッチが装着してある１ヶの重量検知装置を簡単に取り外して設定でき、任意な場所に戻す事が出来る。何所に装着しても重量検知装置の精度が同じである。これが大きな特徴であり、ねじで固定されていればこの様に簡単にはいかない。
このスイッチの開閉信号を無線で受信機に送るので従来のように有線の配線が不要になる。特に小規模の工場でのどこにでも置いてある移動可能な在庫管理に最適である。"Effect of the embodiment"
Since it is configured as described above, the tray (see FIG. 3) moves only for a moment only between the upper and lower limit stoppers, that is, when the weight is reduced from a predetermined value, and thus there is no vibration as in the conventional case.
The number of elastic bodies may be one or two, but the sensitivity of the weight detection device can be further increased by using two elastic bodies attached to the other bearing.
Since the sensitivity of the elastic body is determined, even if the upper and lower limit stopper intervals are roughly set, if the switch opens and closes during this time, a signal is always output near the predetermined value. In the inventory management of goods, since such a highly accurate thing is not required, even such a state is sufficient.
Usually, a plurality of weight detection devices are used and fixed to a saucer and a base (see FIG. 3) with magnets. In this way, the ON / OFF adjustment of the switch can be set by simply removing and setting one weight detection device on which the switch is mounted, and returning it to an arbitrary place. The accuracy of the weight detector is the same no matter where it is installed. This is a big feature, and if it is fixed with screws, it is not as easy as this.
Since the switch open / close signal is sent wirelessly to the receiver, no wired wiring is required as in the prior art. It is especially suitable for movable inventory management that can be found anywhere in a small factory.
