Description
【０００１】[0001]
本考案は複数のロードセルを具備するロードセル式秤に関するものである。 The present invention relates to a load cell type balance having a plurality of load cells.
【０００２】[0002]
従来この種の技術としては、特開平２−１３９６９９号公報及び特公平１−５ ０１６５６号公報に開示されたものがあった。 Conventionally, as this type of technology, there have been those disclosed in Japanese Patent Application Laid-Open No. 2-139699 and Japanese Patent Publication No. 1-01656.
【０００３】 特開平２−１３９６９９号公報に開示されたものは、光学スキャナの窓上に透 明な窓板を形成した後、秤皿を備えたロードセル式秤を載置し、この秤皿に置い た商品のデータを前記光学スキャナで読み取ると共に、重量を軽量するロードセ ル秤を具備する売場専用装置である。この売場専用装置のロードセル秤は２本の ロードセルを有し、このロードセルに取付けた重量受けビームと前記秤皿との間 に弾性パット又はボールベアリング組立体を介在させた構成である。The one disclosed in Japanese Patent Laid-Open No. 2-139699 has a transparent window plate formed on the window of an optical scanner, and then a load cell type balance equipped with a weighing pan is placed on the weighing plate. This is a sales floor dedicated device equipped with a load cell scale that reduces the weight while reading the data of the placed products with the optical scanner. The load cell balance of the device for exclusive use in the sales floor has two load cells, and an elastic pad or a ball bearing assembly is interposed between the weight receiving beam attached to the load cell and the weighing pan.
【０００４】 特公平１−５０１６５６号公報に開示されたものは、光学スキャナに組込まれ たロードセル式秤を有する清掃容易な走査／重量計装置が開示されている。この 走査／重量計装置のロードセル式秤はリターンアームと重量計板の横ずれを吸収 するゴム部を備えた固定具を介在させた構成である。Japanese Patent Publication No. 1-501656 discloses an easy-to-clean scanning / weighing device having a load cell type balance incorporated in an optical scanner. The load cell type balance of this scanning / weighing device has a structure in which a return arm and a fixture having a rubber portion that absorbs lateral displacement of the weighing plate are interposed.
【０００５】[0005]
しかしながら上記重量受けビームと前記秤皿との間にボールベアリング組立体 を介在させた構成では、秤皿の位置決めができず、また秤皿に加えられる衝撃を 緩衝することができなかった。また弾性パット又はゴム部を備えた固定具を介在 させた構成では、この弾性パット又は固定具のゴム部は上下端が固定されるため 、秤皿のたわみによる弾性パット又はゴム部のたわみによる弾力がロードセルに ねじれ作用を与えるため、精度の高い計量が行えないという問題があった。 However, with the configuration in which the ball bearing assembly is interposed between the weight receiving beam and the weighing pan, the positioning of the weighing pan cannot be performed and the impact applied to the weighing pan cannot be buffered. In addition, in the configuration in which the elastic pad or the fixture having the rubber portion is interposed, the upper and lower ends of the rubber portion of the elastic pad or the fixture are fixed, so that the elasticity of the elastic pad or the rubber portion due to the deflection of the weighing pan causes the elasticity. Has a problem that accurate measurement cannot be performed because the load cell twists.
【０００６】 本考案は上述の点に鑑みてなされたもので、緩衝部材を備えた複数のロードセ ルを使用し精度の高い計量を行うことのできるロードセル式秤を提供することを 目的とする。The present invention has been made in view of the above points, and an object of the present invention is to provide a load cell type balance that can perform highly accurate weighing using a plurality of load cells equipped with a cushioning member.
【０００７】[0007]
上記課題を解決するため本考案は、固定端がベースに固定された複数のロード セルを具備し、該ロードセルの可動端に皿受部材を設け、該皿受部材上に弾性材 からなる緩衝部材を介在させて側壁を有する秤皿を支持するようにしたロードセ ル式秤において、緩衝部材は上端で秤皿の裏面を支持する突部と、この突部の下 部で該突部より平面形状の大きい接合部とからなり、この接合部と突部とによっ て秤皿の側壁内面と秤皿裏面との間に空隙を形成することを特徴とする。 In order to solve the above-mentioned problems, the present invention comprises a plurality of load cells having fixed ends fixed to a base, a movable plate of the load cells is provided with a pan receiving member, and a cushioning member made of an elastic material on the pan receiving member. In a load cell type balance that supports a weighing pan having a side wall with a buffer member, the cushioning member has a projection that supports the back surface of the weighing pan at the upper end, and a planar shape from the projection at the lower part of this projection. Is characterized in that a gap is formed between the inner surface of the side wall of the weighing pan and the back surface of the weighing pan by the joining part and the protrusion.
【０００８】[0008]
ロードセル式秤を上記の通り構成することにより、秤皿の撓みによる緩衝部材 に生じる水平方向の応力が、緩衝部材の突部の変形を、接合部と突部と秤皿の側 壁内面と秤皿裏面との間に形成された空隙により吸収するので、緩衝部材を取り 付けた皿受部材に水平方向の力が作用しないため、ロードセルには垂直荷重のみ が作用する。従って、衝撃等に対して緩衝作用があり、精度の高い計量を行うこ とができるロードセルを提供することができる。 By configuring the load cell type balance as described above, the horizontal stress generated in the cushioning member due to the bending of the weighing pan causes the deformation of the protrusion of the cushioning member, the joint portion, the protrusion, and the inner surface of the side wall of the weighing pan to be weighed. Since it is absorbed by the space formed between the dish and the back surface of the dish, no horizontal force acts on the dish receiving member to which the cushioning member is attached, so only the vertical load acts on the load cell. Therefore, it is possible to provide a load cell that has a shock absorbing effect against impacts and the like and can perform highly accurate weighing.

以下、本考案の実施例を図１乃至図４を用いて説明する。図１は本考案のロー ドセル式秤の平面図、図２は図１のＸ−Ｘ断面図、図３は図１のＹ−Ｙ断面図、 図４は本考案のロードセル式秤をカウンタに取り付けた状態を示す斜視図である 。 An embodiment of the present invention will be described below with reference to FIGS. 1 is a plan view of a load cell type balance of the present invention, FIG. 2 is a sectional view taken along line XX of FIG. 1, FIG. 3 is a sectional view of FIG. 1 taken along line YY, and FIG. It is a perspective view showing the state where it was attached.
【００１０】 図示するように、フレーム１１が調整脚１２に支持され、該フレーム１１の両 端側上部には断面略Ｕ字状のベース部材１３が２本平行に配置固定されている。 ベース部材１３のそれぞれの内側にはロードセル取付板１４が固定され、該ロー ドセル取付板１４のそれぞれにはロードセル１５の固定端が固定されている。ロ ードセル１５の可動端には重点板１６が固定され、該ロードセル取付板１６の上 には断面略逆Ｕ字状の皿受部材１７が固定されている。該皿受部材１７の両端部 に緩衝部材１８が設けられ、該緩衝部材１８の上に秤皿１９が配置されている。 即ち、皿受部材１７の両端部上に緩衝部材１８を介在させて秤皿１９が配置固定 されている。２本のロードセル１５，１５は、互いのロードセルの固定端及び可 動端が相反するように配属されている。As shown in the drawing, the frame 11 is supported by the adjusting legs 12, and two base members 13 having a substantially U-shaped cross section are arranged and fixed in parallel on the upper ends of the frame 11 at both ends. A load cell mounting plate 14 is fixed inside each of the base members 13, and a fixed end of a load cell 15 is fixed to each of the load cell mounting plates 14. A weight plate 16 is fixed to the movable end of the load cell 15, and a plate receiving member 17 having a substantially inverted U-shaped cross section is fixed on the load cell mounting plate 16. Buffer members 18 are provided at both ends of the plate receiving member 17, and a weighing pan 19 is arranged on the buffer members 18. That is, the weighing pan 19 is arranged and fixed on both ends of the plate receiving member 17 with the buffer members 18 interposed. The two load cells 15 and 15 are assigned such that the fixed end and the movable end of the load cells are opposite to each other.
【００１１】 秤皿１９は周囲に側壁が形成された形状であり、上面中央部には透明な材料で 形成された検出窓２０が設けられている。また、フレーム１１には開口１１ａが 形成されており、秤底部側から該フレーム１１の該開口１１ａを通して、前記検 出窓２０が覗けるようになっている。即ち、図４に示すようにカウンタ２１の内 部に組み込まれた固定スキャナー上に載置することにより、該固定スキャナーに より検出窓２０の上面に載置された商品のデータを読み取ることができるように なっている。The weighing pan 19 has a shape in which a side wall is formed on the periphery thereof, and a detection window 20 formed of a transparent material is provided at the center of the upper surface. An opening 11a is formed in the frame 11 so that the detection window 20 can be seen through the opening 11a of the frame 11 from the bottom side of the balance. That is, as shown in FIG. 4, by mounting on the fixed scanner incorporated in the inside of the counter 21, the data of the product placed on the upper surface of the detection window 20 can be read by the fixed scanner. It has become like this.
【００１２】 図５は緩衝部材１８を示す図で、同図（ａ）は平面図、同図（ｂ）は側面図で ある。図示するように緩衝部材は上端で秤皿１９の裏面を支持する突部１８ａと 、この突部１８ａの下部で該突部１８ａより平面形状の大きい接合部１８ｂとか らなる。緩衝部材１８は温度による硬度変化の少ないゴム材、例えばシリコン系 ゴム、ウレタン系ゴム、ブチルゴム等の弾性部材からなり、内部に埋め込んだ埋 込ボルト２３｛図５参照｝で高さ調整が可能になっている。FIG. 5 is a view showing the buffer member 18, FIG. 5A is a plan view, and FIG. 5B is a side view. As shown in the figure, the cushioning member is composed of a protrusion 18a that supports the back surface of the weighing pan 19 at the upper end, and a joint portion 18b that has a larger planar shape than the protrusion 18a at the lower portion of the protrusion 18a. The cushioning member 18 is made of an elastic member such as a rubber material whose hardness hardly changes with temperature, for example, silicone rubber, urethane rubber, butyl rubber, etc., and the height can be adjusted by the embedded bolt 23 (see FIG. 5) embedded inside. Is becoming
【００１３】 上記衝部材１８は図６に示すように、皿受部材１７と秤皿１９の間に介在し、 突部１８ａの上端で皿１９の裏面１９ａを支持し、接合部１８ｂの外周は秤皿１ ９の側壁内面１９ｂに接している。そして接合部１８ｂと突部１８ａとによって 秤皿１９の側壁内面と秤皿１９の裏面との間に空隙２２を形成している。As shown in FIG. 6, the impact member 18 is interposed between the plate receiving member 17 and the weighing pan 19, and the upper end of the protrusion 18a supports the back surface 19a of the plate 19, and the outer periphery of the joint 18b is It is in contact with the inner surface 19b of the side wall of the weighing pan 19. A space 22 is formed between the inner surface of the side wall of the weighing pan 19 and the back surface of the weighing pan 19 by the joint portion 18b and the protrusion 18a.
【００１４】 秤皿１９の上面（上表面）に荷重が加わった場合、秤皿１９は図７に示すよう に、１９’の位置から変形して実線のようになると、緩衝部材１８の突部１８ａ は水平方向（矢印Ａ方向）の力を受け変形する。しかしこの変形は空隙２２内に よって側壁内面１９ｂで抑圧されないので、水平方向の力は突部１８ａで吸収さ れてしまうため、皿受部材１７にロードセル１５に影響を与える程の水平方向の 力が作用しなくなるから、従って、ロードセル１５は高精度の計量ができる。When a load is applied to the upper surface (upper surface) of the weighing pan 19, as shown in FIG. 7, when the weighing pan 19 is deformed from the position 19 ′ into a solid line, the protrusion of the cushioning member 18 is formed. 18a is deformed by receiving a horizontal force (direction of arrow A). However, since this deformation is not suppressed by the inner wall surface 19b of the side wall due to the inside of the void 22, the horizontal force is absorbed by the protrusion 18a, so that the horizontal force that affects the load cell 15 to the pan receiving member 17 is increased. Therefore, the load cell 15 can perform high-accuracy weighing.
【００１５】 図８は緩衝部材１８の他の例を示す図である。この例では緩衝部材１８の突部 １８ａは半球形にしている。これにより突部１８ａと秤皿１９の裏面との接触面 積が最小となり、秤皿１９の撓みを吸収する。緩衝部材１８の材料は、図５の場 合と同様、温度による硬度変化の少ないゴム材、例えばシリコン系ゴム、ウレタ ン系ゴム、ブチルゴム等の弾性部材を用いる。なお、接合部１８ｂは円板状でそ の中心が突部１８ａ及び埋込ボルト２３の中心とずれて位置している。接合部１ ８ｂ、秤皿１９の側壁内面１９ｂに接合して秤皿１９の位置決めを行っている。 従って秤皿１９は横ずれを生じないてせ正しい計量を行うことができる。FIG. 8 is a diagram showing another example of the cushioning member 18. In this example, the protrusion 18a of the cushioning member 18 has a hemispherical shape. As a result, the contact area between the protrusion 18a and the back surface of the weighing pan 19 is minimized, and the bending of the weighing pan 19 is absorbed. As the material of the buffer member 18, as in the case of FIG. 5, an elastic member such as a silicone rubber, a urethane rubber, or a butyl rubber whose hardness hardly changes with temperature is used. The joint portion 18b is disc-shaped, and its center is displaced from the centers of the protrusion 18a and the embedded bolt 23. The joint portion 18b and the side wall inner surface 19b of the weighing pan 19 are joined to position the weighing pan 19. Therefore, the weighing pan 19 can perform correct weighing without causing lateral displacement.
【００１６】 図９は緩衝部材１８の他の例を示す図である。この例では緩衝部材１８は全体 が円錐状に形成され、その上端で秤皿１９の裏面を支持し、底部が皿受部材１７ の上部に接している。これにより緩衝部材の上端と秤皿１９の裏面との接触面積 が最小となり、秤皿１９の撓みを吸収しやすい。緩衝部材１８の材料は、図５の 場合と同様、温度による硬度変化の少ないゴム材、例えばシリコン系ゴム、ウレ タン系ゴム、ブチルゴム等の弾性部材を用いる。接合部１８ｂは上記実施例と同 様に秤皿１９の側壁内面１９ｂに接合して秤皿１９の位置決めを行っていない。FIG. 9 is a diagram showing another example of the cushioning member 18. In this example, the cushioning member 18 is formed in a conical shape as a whole, and the upper end of the cushioning member 18 supports the back surface of the weighing pan 19, and the bottom part thereof contacts the upper part of the pan receiving member 17. As a result, the contact area between the upper end of the buffer member and the back surface of the weighing pan 19 is minimized, and the bending of the weighing pan 19 is easily absorbed. As the material of the cushioning member 18, as in the case of FIG. 5, an elastic member such as a silicone-based rubber, a urethane-based rubber, or a butyl rubber, whose hardness hardly changes with temperature, is used. The joint portion 18b is not joined to the side wall inner surface 19b of the weighing pan 19 to position the weighing pan 19 as in the above embodiment.
【００１７】 図１０は緩衝部材１８の他の例を示す図である。この例では緩衝部材１８の突 部１８ａは半球状に形成され、その上部に溝１８ｃを形成して複数に分割してい る。その上端で秤皿１９の裏面を支持し、底部が皿受部材１７の上部に接してい る。これにより突部１８ａの変形がさらに秤皿の撓みを吸収し易くなる。緩衝部 材１８の材料は、図５の場合と同様、温度による硬度変化の少ないゴム材、例え ばシリコン系ゴム、ウレタン系ゴム、ブチルゴム等の弾性部材を用いる。なお、 上記図６，図８，図９，図１０の実施例では、緩衝部材１８の接合部１８ｂが秤 皿１９の側壁１９ｂ内面と接合して秤皿１９の位置決めを行っている。従って、 秤皿１９の側面から押されても秤皿は１９ずれることなく正しい計量を行うこと ができる。FIG. 10 is a diagram showing another example of the cushioning member 18. In this example, the protrusion 18a of the cushioning member 18 is formed in a hemispherical shape, and a groove 18c is formed in the upper portion thereof to divide the cushion member 18 into a plurality of portions. The upper end supports the back surface of the weighing pan 19, and the bottom part contacts the upper part of the pan receiving member 17. This makes it easier for the deformation of the protrusion 18a to absorb the bending of the weighing pan. As the material of the cushioning member 18, as in the case of FIG. 5, a rubber material whose hardness hardly changes with temperature, for example, an elastic member such as silicone rubber, urethane rubber, or butyl rubber is used. In the embodiments shown in FIGS. 6, 8, 9 and 10, the joint portion 18b of the buffer member 18 is joined to the inner surface of the side wall 19b of the weighing pan 19 to position the weighing pan 19. Therefore, even if it is pushed from the side surface of the weighing pan 19, the weighing pan can be accurately measured without being displaced by 19.
【００１８】 図１１は緩衝部材１８の他の例を示す図である。この例では緩衝部材１８の突 部１８ａは半球状に形成され、その上部の中心部に凹部１８ｄを形成し、秤皿１ ９のこの凹部１８ｄに対応する部分には凸部１９ａを形成している。これにより 秤皿１９の凸部１９ａを緩衝部材１８の凹部１８ｄに嵌合させることにより、秤 皿１９の位置決めが行える。緩衝部材１８の材料は、図５の場合と同様、温度に よる硬度変化の少ないゴム材、例えばシリコン系ゴム、ウレタン系ゴム、ブチル ゴム等の弾性部材を用いる。従って、接合部１８ｂと秤皿１９の側壁内面とは接 合しなくてもよい。しかしながら、接合部１８ｂと秤皿１９の側壁１９ｂの内面 と接合させることにより、側壁１９ｂの内面に押されたとき復帰が早く正しい計 量を行うことができる。FIG. 11 is a diagram showing another example of the cushioning member 18. In this example, the projection 18a of the cushioning member 18 is formed in a hemispherical shape, a recess 18d is formed in the center of the upper portion thereof, and a projection 19a is formed in a portion of the weighing pan 19 corresponding to the recess 18d. There is. Accordingly, by fitting the convex portion 19a of the weighing pan 19 into the concave portion 18d of the buffer member 18, the positioning of the weighing pan 19 can be performed. As the material of the buffer member 18, as in the case of FIG. 5, an elastic member such as a silicone rubber, a urethane rubber, a butyl rubber or the like whose hardness hardly changes with temperature is used. Therefore, the joint 18b and the inner surface of the side wall of the weighing pan 19 do not have to be in contact with each other. However, by joining the joint portion 18b and the inner surface of the side wall 19b of the weighing pan 19, it is possible to quickly return to the correct weight when pushed by the inner surface of the side wall 19b.
【００１９】 図１２は緩衝部材１８及び位置決板２４の例を示す図である。この例では緩衝 部材１８の突部１８ａの半球状に形成された点は図８の場合と同様であるが、こ の突部１８ａが嵌合する位置決板２４が秤皿１９の裏面の所定の位置にスポット 溶接等により取付けられている。位置決板２４の突部１８ａが嵌合する部分は、 皿モミにより断面円錐状の凹部２４ａが形成されている。秤皿１９に取り付けた この位置決板２４の凹部２４ａに緩衝部材突部１８ａを嵌合させることにより、 秤皿１９の位置決めができる。緩衝部材１８の材料は、図５の場合と同様、温度 による硬度変化の少ないゴム材、例えばシリコン系ゴム、ウレタン系ゴム、ブチ ルゴム等の弾性部材を用いる。このように位置決板２４を秤皿１９ａに取り付け る構造とすることにより、突部１８ａが秤皿１９の変形に伴って対応するため、 クリープ四隅誤差及び器差が極めてよくなる。本実施例では、緩衝部材１８の突 部１８ａと位置決板２４の凹部２４ａと嵌合が浅いため、秤皿１９の側壁１９が 押されると突部１８ａと凹部２４ａとがずれて正しい計量が行えなくなる。この ため、突起部１８ａと凹部２４ａとがずれて正しい計量が行えなくなる。このた め、突部１８ａと凹部２４ａがずれても直ちに復帰できる程度の間隔を少なくと も設ければ、正しい計量が行える。FIG. 12 is a diagram showing an example of the cushioning member 18 and the positioning plate 24. In this example, the protrusion 18a of the cushioning member 18 is formed in a hemispherical shape as in the case of FIG. 8, but the positioning plate 24 to which this protrusion 18a fits is provided on the back surface of the weighing pan 19. It is attached to the position by spot welding or the like. A recess 24a having a conical cross section is formed by a countersink in a portion of the positioning plate 24 where the protrusion 18a is fitted. The positioning of the weighing pan 19 can be performed by fitting the cushioning member protrusion 18a into the recess 24a of the positioning plate 24 attached to the weighing pan 19. As the material of the cushioning member 18, as in the case of FIG. 5, an elastic member such as a silicone-based rubber, a urethane-based rubber, or a butyl rubber whose hardness hardly changes with temperature is used. With the structure in which the positioning plate 24 is attached to the weighing pan 19a in this manner, the protrusion 18a responds to the deformation of the weighing pan 19, so that the creep four-corner error and the instrumental error become extremely good. In this embodiment, since the protrusion 18a of the cushioning member 18 and the recess 24a of the positioning plate 24 are not fitted to each other shallowly, when the side wall 19 of the weighing pan 19 is pushed, the protrusion 18a and the recess 24a are displaced from each other and correct weighing is performed. I can't do it. For this reason, the protrusion 18a and the recess 24a are displaced from each other and correct measurement cannot be performed. Therefore, proper measurement can be performed by providing at least an interval such that the projection 18a and the recess 24a can be immediately restored even if they are misaligned.
【００２０】 なお、上記実施例では、カウンタ２１の内部に組み込まれた固定スキャナーで 検出窓２０の上面に載置された商品のデータを読み取るスケールスキャナーを例 に説明したが、本考案はこれに限定されるものではなく、複数のロードセルを具 備するロードセル式秤に適用できることは当然である。In the above embodiment, the scale scanner that reads the data of the product placed on the upper surface of the detection window 20 by the fixed scanner incorporated in the counter 21 is described as an example, but the present invention is not limited to this. Of course, the present invention is not limited to this, and can be applied to a load cell type balance equipped with a plurality of load cells.
【００２１】 また、上記実施例では緩衝部材１８の突部１８ａと接合部１８ｂは一体に形成 されたが、これに限定されるものではなく、突部１８ａと接合部１８ｂを別体に 形成し、後に一体に接合する構成としてもよい。また、突部１８ａと接合部１８ ｂは図９に示すように明確に区分できない構成としてもよい。Further, in the above embodiment, the protrusion 18a and the joint 18b of the cushioning member 18 are integrally formed, but the present invention is not limited to this, and the protrusion 18a and the joint 18b are separately formed. It may be configured such that they are integrally joined later. In addition, the protrusion 18a and the joint 18b may not be clearly distinguished as shown in FIG.
【００２２】 また、上記実施例では、緩衝部材１８にシリコン系ゴム、ウレタン系ゴム、ブ チルゴムのゴム材を使用する例を示したが、このゴムの硬度は柔軟な方が秤皿１ ９の撓みを吸収しやすくより効果がある。秤の秤量により異なり、例えば秤量６ Kgの場合は２０度〜３０度の硬度、秤量１５Kgの場合は４０度の硬度、秤量３０ Kgの場合は５０度の硬度のものを用いる。Further, in the above-described embodiment, an example in which a rubber material such as silicone rubber, urethane rubber, or butyl rubber is used for the cushioning member 18 is shown. However, the hardness of the rubber is softer in the weighing pan 19 It is easier to absorb the bending and more effective. The hardness varies depending on the weight of the scale. For example, when the weight is 6 Kg, the hardness is 20 to 30 degrees, when the weight is 15 Kg, the hardness is 40 degrees, and when the weight is 30 Kg, the hardness is 50 degrees.
【００２３】[0023]
以上説明したように本考案によれば、秤皿の撓みによる緩衝部材に生じる水平 方向の応力が、緩衝部材の突部の変形を、接合部と突部と秤皿の側壁内面と秤皿 裏面との間に形成された空隙により吸収するので、緩衝部材を取り付けた皿受部 材に水平方向の力が作用しないため、ロードセルには垂直荷重のみが作用し、精 度の高い計量を行うことができるロードセル式秤を提供することができるという 優れた効果が得られる。 As described above, according to the present invention, the horizontal stress generated in the cushioning member due to the bending of the weighing plate causes the deformation of the protrusion of the cushioning member to cause the joint portion, the protrusion, the inner surface of the side wall of the weighing dish, and the back surface of the weighing dish. Since it is absorbed by the gap formed between the and, the horizontal force does not act on the pan support member with the cushioning member attached, so only the vertical load acts on the load cell, and highly accurate weighing can be performed.
