従来より、ホッパースケールやタンクスケール等の産業用はかりとして、荷重 の検出に圧縮型ロードセルを備えた荷重検出装置が多用されている。 この種の荷重検出装置では、安全性確保のため、風圧や地震等により水平力を 吸収して、ホッパーやタンクの転倒を防止するための機構が必要である。一方、 このように水平力吸収機構は、圧縮型ロードセルの計量精度に影響を及ぼさない ことが必要である。 2. Description of the Related Art Conventionally, a load detection device equipped with a compression type load cell has been widely used for load detection as an industrial scale such as a hopper scale and a tank scale. In order to ensure safety, this type of load detection device requires a mechanism that absorbs horizontal force due to wind pressure, earthquakes, etc., and prevents the hopper and tank from falling. On the other hand, it is necessary that the horizontal force absorption mechanism does not affect the weighing accuracy of the compression type load cell.
【０００３】 上記のように水平力を吸収し、かつ、計量精度を確保するものとして、従来よ り、図５及び図６に示すような荷重検出装置が提供されている。 この荷重検出装置では、ホッパー１の外周の３等分位置に、フランジ２をそれ ぞれ固定し、これら各フランジ２の下面に上側加圧板３をそれぞれ固定すると共 に、各上側加圧板３に対向する架台４の上面に、下側加圧板５をそれぞれ固定し ている。また、上記下側加圧板５の上面には、圧縮型ロードセル６それぞれ固定 して、これら各圧縮型ロードセル６の上部受圧面を上記各上側加圧板３に当接さ せている。As described above, a load detection device as shown in FIGS. 5 and 6 has been provided as a device for absorbing the horizontal force and ensuring the weighing accuracy. In this load detection device, the flanges 2 are fixed to the outer circumference of the hopper 1 at three equally divided positions, and the upper pressure plates 3 are fixed to the lower surfaces of the flanges 2, respectively. Lower pressing plates 5 are fixed to the upper surfaces of the pedestals 4 facing each other. The compression type load cells 6 are fixed to the upper surface of the lower pressure plate 5, and the upper pressure receiving surfaces of the compression type load cells 6 are brought into contact with the upper pressure plates 3.
【０００４】 一方、上記架台４の上面には、ホッパー１の各フランジ２に対応して、一対の ブラケット７をそれぞれ固定し、各ブラケット７とフランジ２を、水平なたすき 棒８でそれぞれ連結している。各たすき棒８にはターンバックル９をそれぞれ介 設しており、このターンバックル９の部分でたすき棒８の張力を調整することが できるようにしている。On the other hand, on the upper surface of the gantry 4, a pair of brackets 7 are fixed respectively corresponding to the respective flanges 2 of the hopper 1, and the brackets 7 and the flanges 2 are connected by a horizontal peg 8 respectively. ing. A turnbuckle 9 is provided on each plow rod 8 so that the tension of the plow rod 8 can be adjusted at the turnbuckle 9.
【０００５】 この図５及び図６でしめす荷重検出装置では、上記各たすき棒８でホッパー１ を水平方向に引っ張ることにより、圧縮型ロードセル６により検出される荷重の 精度を維持しつつ、ホッパー１の適度な横揺れを許容（水平力吸収）する構成と している。In the load detecting device shown in FIGS. 5 and 6, the hopper 1 is pulled horizontally by each of the plow rods 8 to maintain the accuracy of the load detected by the compression type load cell 6, while maintaining the accuracy of the hopper 1. It has a structure that allows moderate lateral vibration (absorption of horizontal force).
【０００６】[0006]
しかしながら、上記のような従来の荷重検出装置では、架台４に多数のブラケ ット７（図５及び図６に示す例では６個）を溶接、ボルト締め等で取付けるため 、架台４に十分な強度を与えるためには補強用梁材を追加する必要がある。その ため、荷重検出装置の周囲の構造を上記補強用梁材を配置可能となるように、設 計、施工上の配慮が必要であった。 However, in the conventional load detecting device as described above, a large number of brackets 7 (6 in the example shown in FIGS. 5 and 6) are attached to the gantry 4 by welding, bolting, etc. It is necessary to add a reinforcing beam to give strength. Therefore, it was necessary to consider the design and construction of the structure around the load detection device so that the reinforcing beam could be placed.
【０００７】 また、多数のたすき棒８及びターンバックル９（図５及び図６に示す例ではそ れぞれ６個）を必要とするため、その取付及び調整作業も必要であり、施工費が 高くなっていた。Further, a large number of plow bars 8 and turn buckles 9 (6 pieces in each of the examples shown in FIGS. 5 and 6) are required, and therefore installation and adjustment work thereof are also required, which results in construction cost. It was getting higher.
【０００８】 さらに、ホッパー１の横揺れ許容範囲の調整は、ターンバックル９の締め緩め により行うため、この調整に熟練が必要であり、調整が容易でなかった。Further, since the lateral sway allowable range of the hopper 1 is adjusted by tightening and loosening the turnbuckle 9, a skill is required for this adjustment and the adjustment is not easy.
【０００９】 本考案の目的は、上記のような従来の荷重検出装置における問題を解決するた めになされたものであり、取付及び調整作業が容易な水平力吸収機構を備えた荷 重検出装置を低コストで提供することを目的としてなされたものである。An object of the present invention is to solve the problems in the conventional load detecting device as described above, and a load detecting device having a horizontal force absorbing mechanism which is easy to mount and adjust. It was made for the purpose of providing a low cost.

従って、本考案は、上部と下部に球面の受圧面を有する圧縮型ロードセルと、 該圧縮型ロードセルの上部受圧面が嵌合する凹面部を有すると共に、上側取付板 に固定した上側加圧板と、上記圧縮型ロードセルの下部受圧面が嵌合する凹面部 を有すると共に、下側取付板に固定した下側加圧板と、上記上側及び下側加圧板 のいずれか一方の外周を一端部の内周に嵌合して、該加圧板の取付板にその一端 部を固定すると共に、いずれか他方の加圧板の外周と他端部の内周との間、及び 該他端部と該加圧板の取付板との間に所定の隙間をそれぞれ設け、側部に上記ロ ードセルのリードケーブルを外部へ引き出すための開口部を有する円筒部材とを 備えることを特徴とする荷重検出装置を提供するものである。 Therefore, the present invention has a compression type load cell having upper and lower spherical pressure receiving surfaces, a concave surface portion to which the upper pressure receiving surface of the compression type load cell is fitted, and an upper pressure plate fixed to an upper mounting plate, The compression type load cell has a concave surface portion to which the lower pressure receiving surface fits, and the outer circumference of one of the lower pressure plate fixed to the lower mounting plate and the upper and lower pressure plates is the inner circumference of one end. And fixing one end of the pressure plate to the mounting plate of the pressure plate, and between the outer periphery of the other pressure plate and the inner periphery of the other end, and between the other end and the pressure plate. A load detecting device, comprising: a cylindrical member having a predetermined gap between the mounting plate and a side member; and a cylindrical member having an opening for pulling out the lead cell of the load cell to the outside. is there.
【００１１】 上記荷重検出装置では、上記他方の加圧板の取付板に、上記円筒部材の他端部 の外周を所定の隙間を隔てて取り囲むリング部材を取付ける構成としてもよい。In the load detecting device, a ring member may be attached to the mounting plate of the other pressure plate to surround the outer periphery of the other end of the cylindrical member with a predetermined gap.
【００１２】[0012]
本考案の荷重検出装置を組み立てる場合には、上側取付板に取付けた上側加圧 板の凹面部に、圧縮型ロードセルの球面の上部受圧面を嵌合させる。また、下側 取付板に取付けた下側加圧板の凹面部に上記ロードセルの球面の下部受圧面を嵌 合させる。そして、例えば上側加圧板の外周に円筒部材の一端部の内周を嵌合さ せ、上側取付板に一端部を固定すると共に、下側加圧板の外周と円筒部材の他端 部の内周との間、及び他端部と下側取付板との間に隙間を隔てる。上記ロードセ ルのリードケーブルは、円筒部材の開口部から外部へ引き出す。上側取付板はホ ッパー等のフランジに固定し、下側取付板は架台等に固定する。 When assembling the load detecting device of the present invention, the spherical upper pressure receiving surface of the compression type load cell is fitted to the concave portion of the upper pressure plate attached to the upper mounting plate. Further, the spherical lower pressure receiving surface of the load cell is fitted to the concave portion of the lower pressure plate attached to the lower mounting plate. Then, for example, by fitting the inner circumference of one end of the cylindrical member to the outer circumference of the upper pressure plate and fixing the one end to the upper mounting plate, the outer circumference of the lower pressure plate and the inner circumference of the other end of the cylindrical member. And a lower mounting plate. The lead cable of the load cell is pulled out from the opening of the cylindrical member. The upper mounting plate is fixed to the flange of the hopper and the lower mounting plate is fixed to the frame.
【００１３】 そのため、本考案の荷重検出装置では、ロードセルの球面の上部受圧面と上側 加圧板の凹面部との嵌合、及びロードセルの球面の下部受圧面と下側加圧板の凹 面部との嵌合、及び下側加圧板の外周と円筒状部材の他端部の内周との隙間によ り、ホッパー等の適度な横揺れが許容（水平力吸収）される。 即ち、本考案の荷重検出装置では、ホッパー等に水平方向の力が作用すると、 上側加圧板が下側加圧板に対して相対的に平行移動すると共に、圧縮型ロードセ ルが傾動する。そして、上記上側加圧板の平行移動は、下側加圧板の外周と円筒 状部材の内周の間の隙間分のみ可能であって、この円筒状部材の内周は下側加圧 板の外周と当接することにより上記平行移動を規制するストッパの役割を果たす 。 また、通常時には下側加圧板の外周と円筒状部材の内周は当接していないため 、計量の精度に影響を及ぼすことはない。Therefore, in the load detection device of the present invention, the spherical upper pressure receiving surface of the load cell and the concave surface portion of the upper pressure plate are fitted together, and the spherical lower pressure receiving surface of the load cell and the concave surface portion of the lower pressure plate are fitted. Due to the fitting and the gap between the outer circumference of the lower pressure plate and the inner circumference of the other end of the cylindrical member, appropriate lateral vibration of the hopper or the like is allowed (horizontal force absorption). That is, in the load detecting device of the present invention, when a horizontal force is applied to the hopper or the like, the upper pressure plate moves in parallel relative to the lower pressure plate and the compression load cell tilts. The parallel movement of the upper pressure plate is possible only for the gap between the outer periphery of the lower pressure plate and the inner periphery of the cylindrical member, and the inner periphery of this cylindrical member is the outer periphery of the lower pressure plate. It plays a role of a stopper that regulates the parallel movement by abutting against. In addition, since the outer circumference of the lower pressure plate and the inner circumference of the cylindrical member are not normally in contact with each other, the weighing accuracy is not affected.
【００１４】 更に、上記下側取付板に、円筒部材の他端部の外周との間に隙間を隔ててリン グ部材を取付けた場合には、この円筒部材の内径を調整することにより、上記横 揺れが可能な範囲を容易に調整することができる。Further, when a ring member is attached to the lower mounting plate with a gap between the lower member and the outer periphery of the other end of the cylindrical member, the inner diameter of the cylindrical member is adjusted so that You can easily adjust the range in which the roll is possible.

On the upper surface of the lower pressure plate 18, there is provided a spherical concave surface portion 18a matching the lower pressure receiving surface 15b of the compression type load cell 15, and the pressure receiving surface 15b is fitted. In the present embodiment, the concave surface portion 18a is formed into a spherical shape as described above, so that the compression type load cell is less likely to be displaced in the later-described rolling motion.
【００１９】 上記上側加圧板１７は円板状の上側取付板１９の下面に固定する一方、下側加 圧板１８は円板状の下側取付板２０の上面に固定しており、これら上側及び下側 加圧板１７、１８が互いに同心状にとなるように配置している。 上記上側及び下側取付板１９，２０には、円周上等角度間隔でボルト挿通孔１ ９ａ，２０ａをそれぞれ設けている。上側取付板１９は、ホッパー（図示せず） のフランジ２の下面にボルト（図示せず）で固定する構成としている。一方、取 付板２０は、架台４の上面にボルト（図示せず）で固定する構成としている。The upper pressure plate 17 is fixed to the lower surface of a disk-shaped upper mounting plate 19, while the lower pressure plate 18 is fixed to the upper surface of a disk-shaped lower mounting plate 20. The lower pressure plates 17 and 18 are arranged so as to be concentric with each other. The upper and lower mounting plates 19 and 20 are provided with bolt insertion holes 19a and 20a at equal angular intervals on the circumference. The upper mounting plate 19 is fixed to the lower surface of the flange 2 of the hopper (not shown) with bolts (not shown). On the other hand, the mounting plate 20 is fixed to the upper surface of the gantry 4 with bolts (not shown).
【００２０】 上記上側加圧板１７の下面には、円筒部材２１の上端を溶接により固定してい る。この円筒部材２１は、その内周を上記したように上側加圧板１７に固定して 上側取付板１９の外周に密接嵌合させている。 一方、上記円筒部材２１の下端側は、その内周が上記したように下側取付板２ ０に固定した下側加圧板１８の外周を所定隙間ｔ２を隔てて取り囲んでいる。ま た、円筒部材２１の下端は、下側取付板２０と所定隙間ｔ１を隔てて対向してい る。上記隙間ｔ２は、ホッパ−（図示せず）からフランジ２を介して作用する水 平力による横揺れを許容する範囲に設定している一方隙間ｔ１は、少なくとも圧 縮型ロードセル１５が荷重を受けて圧縮する分の大きさに設定している。The upper end of the cylindrical member 21 is fixed to the lower surface of the upper pressure plate 17 by welding. The inner periphery of the cylindrical member 21 is fixed to the upper pressure plate 17 as described above, and is closely fitted to the outer periphery of the upper mounting plate 19. On the other hand, the lower end side of the cylindrical member 21 surrounds the outer periphery of the lower pressurizing plate 18 whose inner periphery is fixed to the lower mounting plate 20 as described above with a predetermined gap t2. Further, the lower end of the cylindrical member 21 faces the lower mounting plate 20 with a predetermined gap t1. The gap t2 is set in a range that allows rolling due to horizontal force acting from the hopper (not shown) via the flange 2, while at least the compression load cell 15 receives the load in the gap t1. It is set to the size to be compressed.
【００２１】 更に、円筒部材２１の側面部は、下側取付板１８側の端部から上側取付板１７ 側に向けて溝状に切欠いた開口部２１ａを設け、この開口部２１ａから上記リー ドケーブル１６を外部に引き出す構成としている。Further, the side surface of the cylindrical member 21 is provided with a groove-shaped opening 21a from the end on the lower mounting plate 18 side toward the upper mounting plate 17 side, and from this opening 21a, the lead 21a is formed.

【００２２】 上記構成からなる実施例では、フランジ２を介して伝達されるホッパーの水平 方向の横揺れは、ロードセル１５の上部受圧面１５ａと上側加圧板１７の凹部１ ７ａとが球面嵌合であり、ロードセル１５の下部受圧面１５ｂと下側加圧板１８ の凹部１８ａとが球面嵌合であることから、この各球面嵌合部分で吸収される。 即ち、本実施例では、ホッパーに対して水平方向の力が付加されると、上側加 圧板１７が下側加圧板１８に対して相対的に平行に移動して横揺れすると共に、 圧縮型ロードセルが通常時の軸線Ｌに対して傾動して、上記水平力を吸収する。 上記上側加圧板１７の平行移動は、下側加圧板１８の外周と円筒状部材２１の 内周の間の隙間ｔ２のみ可能であって、この円筒状部材２１の内周は下側加圧板 １７の外周と当接することにより上記平行移動を規制するストッパの役割を果た す。 また、通常時には下側加圧板１７の外周と円筒状部材２１の内周は当接してい ないため、上記のように水平力により横揺れする構成としたことにより、計量の 精度に影響を及ぼすことはない。In the embodiment configured as described above, the horizontal roll of the hopper transmitted through the flange 2 is caused by spherical fitting between the upper pressure receiving surface 15a of the load cell 15 and the recess 17a of the upper pressure plate 17. Since the lower pressure receiving surface 15b of the load cell 15 and the concave portion 18a of the lower pressure plate 18 are spherically fitted, they are absorbed by each spherical fitting portion. That is, in this embodiment, when a horizontal force is applied to the hopper, the upper pressure plate 17 moves relatively parallel to the lower pressure plate 18 and rolls, and the compression type load cell Tilts with respect to the normal axis L to absorb the horizontal force. The parallel movement of the upper pressure plate 17 is possible only in the gap t2 between the outer circumference of the lower pressure plate 18 and the inner circumference of the cylindrical member 21, and the inner circumference of the cylindrical member 21 is the lower pressure plate 17. By making contact with the outer circumference of the, it plays the role of a stopper that regulates the parallel movement. Further, since the outer circumference of the lower pressure plate 17 and the inner circumference of the cylindrical member 21 are not normally in contact with each other, the structure in which the horizontal pressure sways as described above affects the accuracy of weighing. There is no.
【００２３】 上記実施例の荷重検出装置は、下記のようにして組立てられる。 まず、上側取付板１９に上側加圧板１７を固定し、この上側加圧板１７の外周 を円筒部材２１の内周を嵌合すると共に、円筒部材２１の上端を上側取付板１９ に溶接固定する。また、下側取付板２０に下側加圧板１８を固定する。The load detection device of the above embodiment is assembled as follows.

Further, the lower pressure plate 18 is fixed to the lower mounting plate 20.
【００２４】 次に、圧縮型ロードセル１５の上部受圧面１５ａを上側加圧板１７の球面凹部 １７ａに嵌合すると共に、下部受圧面１５ｂを下側加圧板１８の球面凹部１８ａ に嵌合させ、リードケーブル１６を開口部２１ａから外部へ引き出す。Next, the upper pressure receiving surface 15 a of the compression type load cell 15 is fitted into the spherical recessed portion 17 a of the upper pressure plate 17, and the lower pressure receiving surface 15 b is fitted into the spherical recessed portion 18 a of the lower pressure plate 18 to lead the lead. The cable 16 is pulled out from the opening 21a.
【００２５】 更に、上側取付板１９をホッパーのフランジ２にボルトで固定し、下側取付板 ２０を架台４にボルトで固定する。この固定時には、円筒部材２１の下端部の内 周と下側加圧板１８の外周との間、及び円筒部材２１の下端部と下側取付板２０ との間には、隙間ｔ１、ｔ２を設ける。Further, the upper mounting plate 19 is fixed to the flange 2 of the hopper with bolts, and the lower mounting plate 20 is fixed to the base 4 with bolts. During this fixing, gaps t1 and t2 are provided between the inner periphery of the lower end of the cylindrical member 21 and the outer periphery of the lower pressure plate 18, and between the lower end of the cylindrical member 21 and the lower mounting plate 20. ..
【００２６】 上記のように、本実施例では、従来の装置における「たすき棒」に相当する部 材が必要なく、よって、このたすき棒を保持するためにブラケットを取付けるた めに架台を補強用梁材によって補強する必要がない。 また、本実施例では組立て時にターンバックルでたすき棒の張力を調整する必 要がなく、容易に組立及び調整作業を行うことができる。As described above, in this embodiment, a member corresponding to the “plow bar” in the conventional device is not necessary, and therefore, the pedestal is reinforced for attaching the bracket to hold the plow bar. There is no need to reinforce with beam material. Further, in this embodiment, it is not necessary to adjust the tension of the plow bar with the turnbuckle at the time of assembling, and the assembling and adjusting work can be easily performed.
【００２７】 図４は、本考案の変形例を示している。 この変形例では、下側取付板２０に、円筒部材２１の下端部の外周を所定隙間 をあけて取り囲むよにう、ストッパー用リング部材２２を取付けている。 この変形例では、上記のようにストッパー用リング部材２２を設けているため 、このストッパー用リング部材２２の内径を調整することにより、上記水平力に よる横揺れ可能な範囲を容易に調整することができる。FIG. 4 shows a modification of the present invention. In this modification, a stopper ring member 22 is attached to the lower mounting plate 20 so as to surround the outer periphery of the lower end of the cylindrical member 21 with a predetermined gap. In this modified example, since the stopper ring member 22 is provided as described above, by adjusting the inner diameter of the stopper ring member 22, it is possible to easily adjust the rollable range by the horizontal force. You can
【００２８】 即ち、図４に示す変形例では、ストッパー用リング部材２２の内周と円筒状部 材２１の外周が当接することにより上記横揺れを制限する構成として、このスト ッパー用リング部材２２の内周と円筒状部材２１の外周の間の隙間ｔ３の範囲で 横揺れが許容されるため、ストッパー用リング部材２２の内径を大きくすれば横 揺れ可能な範囲を大きくすることができる一方、ストッパー用リング部材２２の 内径を小さくすれば横揺れ可能な範囲を小さくすることができる。That is, in the modified example shown in FIG. 4, the stopper ring member 22 and the cylindrical member 21 are in contact with each other so that the lateral vibration is limited. Rolling is allowed in the range of the gap t3 between the inner circumference of the cylindrical member 21 and the outer circumference of the cylindrical member 21. Therefore, if the inner diameter of the stopper ring member 22 is increased, the range of horizontal shaking can be increased. If the inner diameter of the stopper ring member 22 is reduced, the range in which it can roll laterally can be reduced.
【００２９】 なお、上記実施例において、下側取付板２０をフランジ２側に固定し、上側取 付板１９を架台４側に固定し、図１から図３に示す状態と天地を逆にすることも できる。In the above embodiment, the lower mounting plate 20 is fixed to the flange 2 side and the upper mounting plate 19 is fixed to the gantry 4 side to reverse the state shown in FIGS. 1 to 3 upside down. You can also do it.
【００３０】 また、上記実施例では凹面部１７ａ,１８ａを球面状としているが、この部分 を平面としてもよい。Further, although the concave portions 17a and 18a are spherical in the above embodiment, this portion may be flat.
【００３１】[0031]
以上の説明からも明らかなように、本考案の荷重検出装置は、圧縮型ロードセ ルの上部受圧面と上側加圧板の凹部及びロードセルの下部受圧面と下側加圧板の 凹部とを球面嵌合とすることにより、この球面嵌合部分でブラケットに取付けた ホッパー等の適度な横揺れが許容（水平力吸収）することができる。 As is clear from the above description, the load detecting device of the present invention is such that the upper pressure receiving surface of the compression type load cell and the recess of the upper pressure plate, the lower pressure receiving surface of the load cell and the recess of the lower pressure plate are spherically fitted. By so doing, moderate rolling of the hopper or the like attached to the bracket can be allowed (horizontal force absorption) at this spherical fitting portion.
【００３２】 また、従来のような多数のたすき棒、ターンバックル、たすき棒用のブラケッ ト等の部品が一切不要であるうえ、架台に補強用梁材を追加する必要がないので 、施工費が安くなると共に、上記ターンバックルのような微妙な調整を必要とす る部材が不要であるため、取付け及び調整作業を簡単に行うことができる。その ため、本考案によれば、上記施工費、取付作業等の面か全体的にコストの低減を 図ることができる。In addition, since many parts such as plow bars, turn buckles, brackets for plow bars, etc., which are required in the past, are not necessary at all, and since it is not necessary to add a reinforcing beam member to the frame, the construction cost is low. In addition to being cheaper, since a member such as the turnbuckle that requires delicate adjustment is not required, the mounting and adjusting work can be easily performed. Therefore, according to the present invention, the cost can be reduced as a whole, in terms of the construction cost, the mounting work, and the like.
【００３３】 更に、本考案では、上記下側となる取付板に、円筒部材の他端部の外周との間 に隙間を隔ててストッパー用リング部材を取付けた場合には、該ストッパー用リ ング部材の内径を調整することにより、ホッパー等の横揺れ可能な範囲を簡単に 制限することができる等の種々の利点を有するものである。Further, in the present invention, when the stopper ring member is attached to the lower mounting plate with a gap between the outer periphery of the other end of the cylindrical member, the stopper ring is attached. By adjusting the inner diameter of the member, there are various advantages such as being able to easily limit the range in which the hopper and the like can roll laterally.
