Description
【０００１】[0001]
台はかり、特に薄型平板型はかりに適する多重センサ方式のはかりに関する。 The present invention relates to a multi-sensor type scale suitable for a platform scale, particularly a thin flat plate type scale.
【０００２】[0002]
複数の重量センサに負荷を分散させて荷重し、その重量を測定するはかりにお いては、被測定物の重量により載台が変形することがあり、または載台の変形の 度合いが異なることがあり、載台をセンサのそれぞれの荷重点に固定することは 測定精度に大きな影響を与える。 In a scale that distributes the load to multiple weight sensors and measures the weight, the platform may be deformed or the degree of deformation of the platform may be different depending on the weight of the object to be measured. Yes, fixing the platform to each load point of the sensor has a great influence on the measurement accuracy.
【０００３】 測定精度に影響させずに載台の外れ及び不安定さを無くすために、センサ部を 基台に固定し、載台にはセンサの重点毎に重点と重点受けとの接触点は一義的に 定まる形状の重点受けを設け、基台または載台の一方に棒状物（以下ストッパー ）を固定し、他方にストッパーと協同してその効果を発揮する、ストッパーの径 より大きい径の孔（以下ストッパー受け）を設け、水平方向の異常な移動を防止 し、組立後にストッパーに外れ防止部材を取付ていた（図１）。In order to eliminate the detachment and instability of the mounting base without affecting the measurement accuracy, the sensor unit is fixed to the base, and the mounting base has a contact point between the emphasis and the emphasis receiver for each emphasis of the sensor. A hole with a diameter larger than the diameter of the stopper, which is provided with an unequivocally defined important point holder, fixes a rod-like object (hereinafter referred to as a stopper) to one of the base and the platform, and exerts its effect in cooperation with the stopper on the other. (The following is a stopper holder) to prevent abnormal movement in the horizontal direction, and a stopper member was attached to the stopper after assembly (Fig. 1).
【０００４】 これら従来方法は、ストッパーとストッパー受けが異なる外形部材に設けられ ているために組立誤差も大きくなり、また載台および基台の変形による寸法変化 も大きく、ストッパーとストッパー受けのクリアランスを大きく取るか、特別な 組立寸法管理をする必要があった。 また、外れ防止部材を組立後取付調整する必要があった。In these conventional methods, since the stopper and the stopper receiver are provided on different external members, the assembly error is large, and the dimensional change due to the deformation of the mounting base and the base is large, and the clearance between the stopper and the stopper receiver is large. It was necessary to take it large or to manage the special assembly dimensions. Further, it is necessary to adjust the attachment of the detachment preventing member after assembling.
【０００５】[0005]
製品のコストを押し上げる原因となる特別な組立寸法管理や組立後調整を無く すことが本考案の課題である。 It is an object of the present invention to eliminate special assembly dimensional control and post-assembly adjustment that cause the cost of the product to be increased.
【０００６】[0006]
【課題を解決するための手段】 重点を形成している板と取付板とを自由に動くジョイントピンで連結し、重量 センサの近傍に外れ防止装置を完成した重量センサ組立としてユニット化し、取 付板に載台を固定する。[Means for Solving the Problems] A plate that forms an important point and a mounting plate are connected by a freely moving joint pin, and a detachment prevention device is unitized as a completed weight sensor assembly in the vicinity of the weight sensor. Fix the platform to the plate.

図１は従来技術の典型を示す断面図である。図２は本考案の実施例を図１と対 応して示した物で、段絞りにより載台への取付面を形成した取付板（７）をジョ イントピン（８）で緩く結合した重点を形成した重点板（１４）をセンサに固定 した外れ防止装置を備えたユニット化された重量センサ組立にの取付板に載台が 取付ネジ（１８）で固定されている。 FIG. 1 is a sectional view showing a typical prior art. FIG. 2 shows an embodiment of the present invention in correspondence with FIG. 1, in which a mounting plate (7) having a mounting surface for a mounting table formed by step drawing is loosely connected with a joint pin (8). The mounting table is fixed by mounting screws (18) to a mounting plate of a unitized weight sensor assembly equipped with a detachment prevention device that fixes the formed emphasis plate (14) to the sensor.
【０００８】 以下本考案の実施例の詳細を図３、図４に基づき説明する。図３は本考案の一 実施例の組立分解図、図４は平面図および要部の断面図である。The details of the embodiment of the present invention will be described below with reference to FIGS. 3 and 4. FIG. 3 is an exploded view of an embodiment of the present invention, and FIG. 4 is a plan view and a sectional view of a main part.
【０００９】 起歪体（１１）は弾性材で形成され、平板状の、大きさの異なるコ字状部材を 向き合わせ、小さい部材を隙間を取って大きい部材に填め込み、双方の縦板の中 央部を横板で連結した形状をし、小さい方の部材の自由端（内側）には重点板の 固定用組立ネジ受けが、大きい方の部材の自由端（外側）にはベースへの固定ネ ジ受けが中央の連結板の中心を通る直線上に設けてあり、中央の連結板にはスト レンゲージ（１２）が中央に貼付してある。The flexure element (11) is made of an elastic material, and flat plate-shaped U-shaped members having different sizes are faced to each other, and a small member is inserted into a large member with a gap left between the vertical plates of both members. The center part is connected by a horizontal plate. The smaller end of the free end (inside) of the smaller member has the screw assembly for fixing the weight plate, and the larger end of the free end (outside) is connected to the base. A fixed screw receiver is provided on a straight line passing through the center of the central connecting plate, and a strain gauge (12) is attached to the center of the central connecting plate.
【００１０】 重点板（１４）は、重点をストレンゲージの中心部上部に配置する機能と載台 への取付板と結合させる機能を有しており、前部に二つの組立ネジ通し孔結ぶ線 上の中央に半球形状の重点（４）を取付け、後部には取付板（７）を自由に動け る様に取り付けるためのジョイントピン（８）の外径より大きい、その上面がザ グリ加工されたジョイントピン通し孔が設けられている。The emphasis plate (14) has a function of arranging the emphasis on the upper part of the center of the strain gauge and a function of connecting with the mounting plate to the mounting table, and a line connecting the two assembly screw through holes to the front part. The hemispherical point (4) is attached to the center of the upper part, and the rear side is larger than the outer diameter of the joint pin (8) for attaching the mounting plate (7) so that it can move freely. A joint pin through hole is provided.
【００１１】 取付板（７）は載台に接触する平面と、その両側のジョイントピン（８）のか しめたフランジ部の厚みより厚い段差のあるジョイントピン通し孔を設ける平面 の二段に曲げられ、ジョイントピン通し孔は重点板（１４）のそれと同じくジョ イントピンの外径より大きく、重点板に対面する面はザグリ加工されている。The mounting plate (7) is bent in two steps, that is, a plane that comes into contact with the mounting table and a plane that has a joint pin through hole with a step difference that is thicker than the thickness of the crimped flange portions of the joint pins (8) on both sides. The joint pin through hole is larger than the outer diameter of the joint pin like that of the weight plate (14), and the surface facing the weight plate is counterbored.
【００１２】 ジョイントピン（８）は中空リベットであり、組立られた時、取付板（７）と 重点板（１４）との間に力が加わらない充分な余裕を有してかしめられ、取付板 と重点板は自由に動ける形で連結されている。The joint pin (8) is a hollow rivet, and when assembled, it is caulked with a sufficient margin so that no force is applied between the mounting plate (7) and the weight plate (14), And the emphasis plate are connected so that they can move freely.
【００１３】 重点（４）が固定され、取付板（７）がジョイントピン（８）により自由に動 ける形で連結された重点板（１４）を、スペーサー（１３）を介して組立ネジ（ １５）で起歪体（１１）にしっかり固定する事で、本考案の載台外れ防止装置を 備えた起歪体組立が完成する。 この起歪体組立をベース（２）の４隅にスペーサ（１３）を介して固定ネジ（ １６）でしっかり固定し、後述の重点受け（５）を取り付けた載台を取付ネジで 固定する事で台秤の計量部は完成する。The emphasis plate (14), to which the emphasis point (4) is fixed and the attachment plate (7) is connected by the joint pin (8) in a freely movable manner, is assembled with the assembly screw (15) via the spacer (13). By firmly fixing to the strain-flexing body (11) by (4), the strain-flexing body assembly including the mounting table detachment prevention device of the present invention is completed. Secure this flexure assembly to the four corners of the base (2) through the spacers (13) with the fixing screws (16), and fix the mounting table to which the later-described weight receiver (5) is attached with the attaching screws. This completes the weighing section of the platform scale.
【００１４】 重点受け（５）は重点（４）を構成する半球の半径より大きい半径の球面の凹 部を有した鋼材の部材で、重点に対応する位置の載台に、球凹面を重点に対面し て固定される。載台の自重により、重点の頂点と重点受けの頂点が接触する形で 重点と重点受けの位置は一義的に決定される。The emphasis receiver (5) is a steel member having a spherical concave portion having a radius larger than the radius of the hemisphere forming the emphasis (4), and the spherical concave surface is used as an emphasis on the platform at the position corresponding to the emphasis. It is fixed face to face. Due to the weight of the platform, the positions of the emphasis points and the emphasis points are uniquely determined so that the top points of the emphasis points and the top points of the emphasis points contact each other.

センサの重点の近傍に目的の作用をする載台外れ防止装置が完成し、センサ組 立として所定の位置に取り付けるだけで目的を達し、従来技術に於ける外形部品 の変形の影響が極めて少なく、簡単に組み立てる事が出来る。 We have completed a platform removal prevention device that has the desired effect near the sensor's focus, and it achieves its purpose simply by mounting it in a predetermined position as a sensor assembly, and the effect of deformation of external parts in the conventional technology is extremely small. It can be easily assembled.
