本考案は電動モータの据付部材に係り、特に秤量装置に内蔵される校正用分銅 昇降機構の駆動装置として用いられる電動モータの据付部材に関する。 The present invention relates to an electric motor installation member, and more particularly to an electric motor installation member used as a drive device for a calibration weight lifting mechanism incorporated in a weighing device.

例えば電磁平衡式の秤量装置等、精密な重量測定装置においては校正用の分銅 を内蔵しているものがある。内蔵分銅を有する装置では校正動作を行う分銅昇降 機構が組み込まれており、装置外部からのスイッチ操作によりワンタッチで校正 が行われるようになっている。 For example, some precision weight measuring devices, such as electromagnetic balance weighing devices, have a built-in calibration weight. A device with a built-in weight incorporates a weight lifting mechanism that performs a calibration operation, and calibration can be performed with one touch by operating a switch from outside the device.
【0003】 図3は考案者らが先に提案している電磁平衡式秤量装置に於ける内蔵分銅昇降 機構を示す(実願昭63−72799号)。FIG. 3 shows a built-in weight raising / lowering mechanism in an electromagnetic balance type weighing device that the inventors have previously proposed (Japanese Patent Application No. 63-72799).
【0004】 図示の構成では内蔵分銅はリング状に形成された大型の分銅31と小型の分銅 32とを有している。33はこれら大小の内蔵分銅31、32を支持しかつこれ らの分銅を昇降させる支持部材であり、33a、33b、33cはこの支持部材 33のうち平面略「コ」字形の支持部材枠体33dから枠体内部に展出した内蔵 分銅支持アームである。各内蔵分銅31及び32はこの支持アーム33a、33 b、33cに支持され、ほぼ同心に配置され、かつその共通の中心は秤量物の荷 重をビーム側に伝達する荷重伝達軸の軸心と一致するように配置される。In the configuration shown, the built-in weight has a large weight 31 and a small weight 32 formed in a ring shape. Reference numeral 33 is a support member that supports these large and small built-in weights 31 and 32 and that raises and lowers these weights. 33a, 33b, and 33c are support member frame bodies 33d that are substantially U-shaped in plan view among the support members 33. It is a built-in weight support arm that extends from the inside to the frame. The built-in weights 31 and 32 are supported by the support arms 33a, 33b, 33c and arranged substantially concentrically, and their common center is the axis of the load transmission shaft for transmitting the load of the weighing object to the beam side. Arranged to match.
【0005】 次にこの支持部材33の枠体33dの四隅には支持ピン34a、34b、34 c、34dが挿通され、支持部材33はこのピン34a〜34dに沿って前記荷 重伝達軸の軸心に沿うように各内蔵分銅31、32を水平状態に保持したまま昇 降するようになっている。枠体33dのうち対向する辺部において突出位置させ た各昇降用突片33e、33fに対して昇降機構が接触係合することにより支持 部材33およびこの支持部材33に支持された内蔵分銅31及び32を昇降させ るようになっている。Next, support pins 34a, 34b, 34c, 34d are inserted into the four corners of the frame 33d of the support member 33, and the support member 33 extends along the shafts of the load transmission shaft along the pins 34a to 34d. The built-in weights 31 and 32 are designed to move up and down while being held horizontally so as to follow the heart. The supporting member 33 and the built-in weight 31 supported by the supporting member 33 when the elevating mechanism comes into contact with the elevating protrusions 33e and 33f that are projected on the opposite sides of the frame 33d. It is designed to raise and lower 32.
【0006】 35はギヤドモータ36に接続されて回転する回転軸である。回転軸35に設 けられた第1カム37と第2カム38のうち、第1カム37は支持部材33の昇 降用突片33fの下面と接触しており、別の第2カム38は昇降運動伝達機構の 一部を成す第1揺動板40の一端の下面に接触している。この第1の揺動板40 のカム38接触側と対向する側の端部は支点41によりX1−Y1方向に揺動す るようになっている。次に42はこの第1の揺動板40に対してほぼ直角をなす ように配置された第2揺動板であり、支点43により前記突辺33eと接触する 側の端部がX2−Y2方向に揺動し、第1揺動板40に接触する側の端部は第1 揺動板40の下面に接触位置するように配置してある。Reference numeral 35 is a rotary shaft that is connected to a geared motor 36 and rotates. Of the first cam 37 and the second cam 38 provided on the rotary shaft 35, the first cam 37 is in contact with the lower surface of the ascending / descending projection 33f of the support member 33, and the other second cam 38 is The lower surface of one end of the first oscillating plate 40 forming a part of the up-and-down motion transmission mechanism is in contact. The end of the first swing plate 40 facing the cam 38 contact side swings in the X1-Y1 direction by a fulcrum 41. Next, 42 is a second oscillating plate which is arranged so as to form a right angle with respect to the first oscillating plate 40, and an end portion on the side where the fulcrum 43 contacts the projecting side 33e is X2-Y2. The end on the side that swings in the direction and comes into contact with the first swing plate 40 is disposed so as to be in contact with the lower surface of the first swing plate 40.
【0007】 以上の構成において、先ず、各内蔵分銅31及び32を上昇させて、電磁部側 に対する荷重伝達部材である浮枠(図示せず)に荷重がかからない状態、つまり 秤量物の荷重測定が可能な状態とするには次のよに作動する。In the above-described configuration, first, the built-in weights 31 and 32 are lifted so that no load is applied to the floating frame (not shown) that is a load transmission member for the electromagnetic section side, that is, the load measurement of the weighing object is performed. To make it possible, operate as follows.
【0008】 先ず前記ギヤドモータ36を作動させることにより回転軸35を介して第1、 第2の各カム37及び38を回転させる。第1カム37の回転によりこのカム3 7に接触する昇降用の突片33fが上方X3方向に押し上げられる。同様に昇降 運動伝達機構のうち端部の一方が第2カム38に接触する第1揺動板40のカム 接触端部を押し上げる。これにより反対側の端部は支点41を中心としてY1方 向に下降し、第2揺動板42の端部を同方向に押し下げる。これにより第2揺動 板42の昇降用の突片33e側の端部はX2方向に上昇し、この突片を同方向に 押し上げる。つまり各カム37、38の回転により各昇降用突片33e、33f は同時に押し上げられる。この作動により支持部材33は各ピン34a〜34d に沿って上昇し、この支持部材33に支持された各内蔵分銅31及び32は水平 状態を維持したまま上昇する。続いて上昇状態でカム37、38の回転を停止し 、各内蔵分銅を支持する。これにより各内蔵分銅31及び32の荷重は全て支持 部材33により支持され、荷重を伝達する部材である浮枠には秤量皿に載置され た秤量物の荷重のみが伝達される。First, the geared motor 36 is operated to rotate the first and second cams 37 and 38 via the rotary shaft 35. By the rotation of the first cam 37, the ascending / descending projection 33f that comes into contact with the cam 37 is pushed upward in the X3 direction. Similarly, one of the ends of the ascending / descending movement transmission mechanism pushes up the cam contact end of the first rocking plate 40 in contact with the second cam 38. As a result, the end on the opposite side descends in the Y1 direction around the fulcrum 41, and the end of the second swing plate 42 is pushed down in the same direction. As a result, the end portion of the second swing plate 42 on the side of the ascending / descending projection piece 33e rises in the X2 direction, and pushes this projection piece in the same direction. In other words, the rotation of the cams 37, 38 simultaneously pushes up the lifting protrusions 33e, 33f. By this operation, the support member 33 rises along the pins 34a to 34d, and the built-in weights 31 and 32 supported by the support member 33 rise while maintaining the horizontal state. Subsequently, the cams 37 and 38 are stopped from rotating in the ascended state to support the built-in weights. As a result, the loads of the internal weights 31 and 32 are all supported by the support member 33, and only the load of the weighing object placed on the weighing pan is transmitted to the floating frame which is a member for transmitting the load.
【0009】 校正を行う場合には前記機構は次の動作をする。ギヤドモータ36を作動させ ることにより第1、第2の各カム37、38を逆転させる。これにより、前述の 上昇時と逆に作動し、支持部材33は徐々に下降する。支持部材33による各内 蔵分銅31及び32の支持高さは予め相違させてあるので、この下降により先ず 小型の内蔵分銅32の下面が前記浮枠に載置され、この分銅32の荷重が浮枠に 伝達される。更に支持部材33を下降させて大型の内蔵分銅31が浮枠に載置さ れ、浮枠に対しては両内蔵分銅31及び32の荷重が伝達されることになる。即 ち、秤量装置のうち精密重量測定モードの校正を行う場合には小型内蔵分銅32 のみを浮枠に載置させる。これにより精密重量測定モードの校正に適した重量の 小型の内蔵分銅32により正確な校正を行うことができる。また大重量測定モー ドの校正を行う場合には小型の内蔵分銅32及び大型の内蔵分銅31の合計の荷 重により校正を行う。また符号44は回転軸35の回転角度を検出する検知装置 であって、例えばフォトセンサで構成され、回転軸35に設けられたフィン35 aの位置により信号を発信して、回転軸35の回転角、即ちこの回転軸35に設 けられたカム37、38の回転角に対応してギヤドモータ36をオン・オフ制御 するための装置である。When performing calibration, the mechanism operates as follows. By operating the geared motor 36, the first and second cams 37, 38 are reversed. As a result, the operation is performed in the opposite manner to the above-described upward movement, and the support member 33 is gradually lowered. Since the support heights of the internal weights 31 and 32 by the support member 33 are made different in advance, the lower surface of the small built-in weight 32 is first placed on the floating frame by this lowering, and the load of the weight 32 floats. It is transmitted to the frame. Further, the support member 33 is lowered to place the large built-in weight 31 on the floating frame, and the loads of both built-in weights 31 and 32 are transmitted to the floating frame. Immediately, when calibrating the precision weighing mode of the weighing device, only the small built-in weight 32 is placed on the floating frame. As a result, accurate calibration can be performed by the small built-in weight 32 having a weight suitable for calibration in the precision weight measurement mode. When calibrating the large weight measurement mode, the calibration is performed by the total weight of the small built-in weight 32 and the large built-in weight 31. Reference numeral 44 is a detection device for detecting the rotation angle of the rotary shaft 35, which is composed of, for example, a photo sensor and transmits a signal according to the position of the fin 35 a provided on the rotary shaft 35 to rotate the rotary shaft 35. It is a device for on / off controlling the geared motor 36 in accordance with the angle, that is, the rotation angle of the cams 37, 38 provided on the rotary shaft 35.

以上、リング型の内蔵分銅を昇降させる昇降機構の構造を説明したが、内蔵分 銅はこの外棒状のもの等各種の形状のものが用いられているが、何れの場合も分 銅の昇降機構は駆動装置である電動モータにより作動する構成となっている点は 同じであって、内蔵分銅の形状の如何に係りなく内蔵分銅昇降機構として下記の 如く共通の問題点を有している。 The structure of the lifting mechanism that raises and lowers the ring-type built-in weight has been described above. As the built-in weight, various shapes such as this outer rod shape are used. Are the same in that they are operated by an electric motor that is a drive unit, and have the following common problems as an internal weight lifting mechanism regardless of the shape of the internal weight.
【0011】 先ず内蔵分銅を必要とする秤量装置は電子平衡式の秤量装置等、精密で精度の 高い秤量装置であるため、モータ等の駆動部から発生する振動による悪影響を極 力低減する必要がある。この低減手段として前記先行技術においては、駆動装置 であるギヤドモータ36を秤量機構から極力離して配置する構成が採用されてい るが、問題の根本的な解決にはなっておらず、しかも回転軸35の全長が長くな ることにより軸の振れや振動等が生じ易くなっている。First, since the weighing device that requires the built-in weight is a precise and highly accurate weighing device such as an electronic balance type weighing device, it is necessary to minimize the adverse effects of vibrations generated by the drive unit such as the motor. is there. As a means for reducing this, in the above-mentioned prior art, a configuration is adopted in which the geared motor 36, which is a drive device, is arranged as far as possible from the weighing mechanism, but this is not a fundamental solution to the problem and the rotary shaft 35 As the overall length of the shaft increases, shaft runout and vibration are likely to occur.
【0012】 回転軸35とギヤドモータ36との間には軸心のずれやギヤドモータ36の回 転軸36aと回転軸35との取り合わせ状態の変位を吸収するために通常の軸接 続の場合と同様に大型のカップリング45が設けられている。なお、場合によっ ては回転軸35が二分され、この分割部分にさらに別のカップリングが配置され ることにより前記変位をより効果的に吸収する構成とされることもある。しかし カップリング45のような変位吸収を主目的とするカップリングはカップリング 自体が弾性変形するように構成されているため、回転軸35に対するギヤドモー タ36側の回転の伝達がやや不正確性になる可能性がある。特に図示の構成の如 く回転軸35が1/4回転若しくは半回転することにより昇降機構が作動するよ うな構成では、内蔵分銅31、32の昇降に時間的ずれを生じる可能性がある。The rotation shaft 35 and the geared motor 36 have a shaft center misalignment and the displacement of the rotation shaft 36 a of the geared motor 36 and the rotation shaft 35 in the assembled state are absorbed in the same manner as in the case of a normal shaft connection. Is provided with a large coupling 45. In some cases, the rotary shaft 35 is divided into two parts, and another coupling is arranged in this divided part to more effectively absorb the displacement. However, since the coupling such as the coupling 45 whose main purpose is to absorb displacement is configured such that the coupling itself is elastically deformed, the transmission of the rotation of the geared motor 36 side with respect to the rotating shaft 35 is slightly inaccurate. Could be. In particular, in the structure in which the lifting mechanism operates by rotating the rotating shaft 35 by a quarter rotation or a half rotation as in the illustrated structure, there is a possibility that the built-in weights 31 and 32 are lifted and lowered in time.
【0013】 更に図3の内蔵分銅昇降機構を組み込む秤量装置においては、荷重伝達機構、 秤量機構等各種の機構や電子回路等が収納されているため、内蔵分銅昇降機構の 配置には制約が多い。例えば大型のカップリング45や角度検知器44の設置の ためにには比較的大きなスペースを必要とする。またカップリング45による回 転のずれを考慮し、回転軸35の実際の回転角度を正確に測定するためには角度 検知器44はギヤドモータ36から見てカップリング45以降の部分に配置され ねばならず、これらの部材の位置設定は秤量装置設計上の負担の一つとなってい る。Further, in the weighing device incorporating the built-in weight lifting mechanism of FIG. 3, various mechanisms such as a load transmission mechanism and a weighing mechanism, electronic circuits, etc. are housed, so there are many restrictions on the arrangement of the built-in weight lifting mechanism. .. For example, a relatively large space is required to install the large coupling 45 and the angle detector 44. Further, in order to accurately measure the actual rotation angle of the rotary shaft 35 in consideration of the rotational deviation due to the coupling 45, the angle detector 44 must be arranged in the portion after the coupling 45 as viewed from the geared motor 36. However, setting the positions of these members is one of the burdens in designing the weighing device.

本考案は上述の問題点に鑑み構成されたものであって、秤量装置の内部機構の 駆動源である電動モータを所定の場所に据え付ける部材であって、ゴム等の可撓 性を有する材料より成形され、かつその構成は電動モータを収納する例えば略円 筒形に形成された収納部と、この収納部と一体的に形成されている据え付け部と を有し、電動モータはこの据付部材を介して所定の場所に取り付けられる。 The present invention is configured in view of the above problems, and is a member for mounting an electric motor, which is a drive source of the internal mechanism of a weighing device, at a predetermined place, and is made of a flexible material such as rubber. The electric motor has a storage part that is molded and has a configuration, for example, formed into a substantially cylindrical shape for storing the electric motor, and a mounting part that is integrally formed with the storage part. It is mounted in place via the.

前記可撓性を有する材料からなる据付部材によりモータは所定の場所に据え付 けられ、モータの振動や作動音はこの据え付け部材により殆ど吸収される。また 据え付け部材が弾性変形することによりモータの軸と機構作動用の回転軸との取 り合わせ部の変位は吸収されるため、変位吸収のための大型カップリングは不要 となる。 The motor is installed in a predetermined place by the installation member made of the flexible material, and the vibration and operating noise of the motor are almost absorbed by the installation member. Further, the elastic deformation of the mounting member absorbs the displacement of the assembling portion of the motor shaft and the rotary shaft for operating the mechanism, so that a large coupling for absorbing the displacement is unnecessary.

以下本考案の実施例を図面を参考に具体的に説明する。 Embodiments of the present invention will be specifically described below with reference to the drawings.
【0017】 図1において矢印1はモータ据え付け用の部材(以下単に「据付部材」と称す る)、矢印2はこの据付部材1により支持され所定の場所に据え付けられるギヤ ドモータである。In FIG. 1, an arrow 1 indicates a member for motor installation (hereinafter simply referred to as “installation member”), and an arrow 2 indicates a geared motor supported by the installation member 1 and installed at a predetermined place.
【0018】 図示の据付部材1はゴムや軟質プラスチック等の可撓性を有する材料により型 成されている。3は据付部材のうちギヤドモータ2を収納する収納部であって、 ギヤドモータ2を収納する空間部3aを有する。収納するギヤドモータ2 密着す るため、この空間部3aの内部形状はギヤドモータ2の外形形状とほぼ等しい形 状に形成されている。またその外形全体は図示の例では略円筒形に形成されてい る。4は収納部3に対して一体的に形成された据付板であって、この据付板4に は据え付け用のボルトが挿通するボルト孔4aが複数個所に形成されている。The illustrated mounting member 1 is made of a flexible material such as rubber or soft plastic. Reference numeral 3 denotes a housing portion that houses the geared motor 2 among the installation members, and has a space portion 3a that houses the geared motor 2. Since the geared motor 2 to be housed is in close contact with the geared motor 2, the internal shape of the space 3a is formed to be substantially the same as the outer shape of the geared motor 2. In addition, the entire outer shape is formed in a substantially cylindrical shape in the illustrated example. Reference numeral 4 denotes an installation plate integrally formed with the storage portion 3, and the installation plate 4 has a plurality of bolt holes 4a through which installation bolts are inserted.
【0019】 一方据付部材1の収納部3に収納されるギヤドモータ2は既存のものであって 、モータ本体部2aとこの本体部2aに連設するギヤ収納部2bとを有し、この ギヤ収納部2bからモータ回転軸2cが突出位置している。またモータ回転軸2 aと対向する側のモータ本体端部には電源コード2dが接続している。On the other hand, the geared motor 2 housed in the housing part 3 of the installation member 1 is an existing one, and has a motor body 2a and a gear housing 2b connected to the body 2a. The motor rotating shaft 2c is located so as to project from the portion 2b. A power cord 2d is connected to the end of the motor body on the side facing the motor rotation shaft 2a.
【0020】 上記のギヤドモータ2は図に示す矢印の如く据付部材1の収納部3の空間部3 aに対してモータ後端部から挿入される。空間部3aの内径はギヤドモータ2の 外径とほぼ等しく形成されているので収納部3に挿入されたギヤドモータ2は収 納部3に確実に保持される。なお収納部3の前部端縁にはギヤドモータ2の先端 部に形成されたモータ取付片2e、2eに対応する形状に成形された凹所3b、 3bが位置し、ギヤドモータ2が収納部3に収納されると共にこのモータ取付片 2eの各々が前記凹所3bにそれぞれ位置することによりギヤドモータ2は収納 部3により確実に保持される。なお空間部3aは収納部3の後端部においても開 口しており、ギヤドモータ2の後端部に接続している電源コード2dはギヤドモ ータ収納後はこの収納部3の後部開口から外部に突出位置する。The geared motor 2 is inserted from the rear end of the motor into the space 3a of the housing 3 of the installation member 1 as shown by the arrow in the figure. Since the inner diameter of the space 3a is formed to be substantially the same as the outer diameter of the geared motor 2, the geared motor 2 inserted in the storage 3 is securely held in the storage 3. In addition, recesses 3b, 3b formed in a shape corresponding to the motor mounting pieces 2e, 2e formed at the tip of the geared motor 2 are located at the front end edge of the storage portion 3, and the geared motor 2 is stored in the storage portion 3. Since the motor mounting pieces 2e are housed and respectively located in the recesses 3b, the geared motor 2 is securely held by the housing portion 3. The space 3a is also open at the rear end of the storage unit 3, and the power cord 2d connected to the rear end of the geared motor 2 is externally opened from the rear opening of the storage unit 3 after storing the geared motor. Is located at the protruding position.
【0021】 以上の手順で据付部材1にギヤドモータ2を収納した状態に予め構成しておき 、この構成物を秤量装置の内蔵分銅昇降機構に対して機構作動用の駆動装置とし て組み込む。なお据付部材1の据付板4の裏面には粘着材を塗布したり、両面粘 着テープを張り付ける等しておけば、この粘着材により駆動装置を秤量装置の所 定の場所に張り付けて仮止めし、しかる後にボルト止めすることにより、据付け 作業を容易に実施することができる。According to the above procedure, the geared motor 2 is housed in the installation member 1 in advance, and this component is incorporated into the built-in weight lifting mechanism of the weighing device as a drive device for operating the mechanism. If the back surface of the installation plate 4 of the installation member 1 is coated with an adhesive material or a double-sided adhesive tape is attached, the drive device can be attached to a predetermined place of the weighing device with this adhesive material. Installation work can be carried out easily by stopping and then bolting.
【0022】 ギヤドモータ2を収納保持する据付部材1は前記した如く可撓性材料により形 成されているため、ギヤドモータ2に接続する機構側の回転軸(図3の回転軸3 5と同様のもの)とモータ回転軸2cとの取り合わせが変位しても、この変位は 可撓性を有する据付部材1が弾性変形することにより吸収するため、ギヤドモー タ2のモータ回転軸2cとこのモータ回転軸に接続する機構側の回転軸との接続 は小型のカップリングを用いれば十分であり、前述の如き変位吸収型の大型カッ プリングを一個または複数個設ける必要はない。また場合によってはカップリン グを用いずにモータ回転軸と機構側の回転軸をとを鑞付け、接着等で半永久的に 一体化させるように接続する方法を用いることも可能である。なお、据付部材1 の取り付けを調整するために据付板4に形成されたボルト孔4aの少なくも一部 を長孔としておくと据え付け作業はより容易となる。Since the installation member 1 that houses and holds the geared motor 2 is made of a flexible material as described above, the rotation shaft on the side of the mechanism connected to the geared motor 2 (similar to the rotation shaft 35 in FIG. 3). ) And the motor rotating shaft 2c are displaced, this displacement is absorbed by the elastic mounting member 1 elastically deforming, so that the motor rotating shaft 2c of the geared motor 2 and this motor rotating shaft 2c are absorbed. It is sufficient to use a small coupling for connection with the rotating shaft on the side of the mechanism to be connected, and it is not necessary to provide one or more large displacement absorption type couplings as described above. In some cases, it is also possible to use a method in which the motor rotation shaft and the rotation shaft on the mechanism side are brazed and connected so as to be semipermanently integrated by bonding or the like without using coupling. It should be noted that if at least a part of the bolt holes 4a formed in the installation plate 4 for adjusting the attachment of the installation member 1 is a long hole, the installation work will be easier.
【0023】 なお、ギヤドモータ2の周囲が収納部3により覆われるため、モータの作動に より発生した熱が外部に放散され難くなるが、秤量装置の内部分銅昇降機構を作 動させる構成の場合には一回のモータの作動時間は5〜6秒程度であり、かつ校 正作業そのものが頻繁に行われる作業ではないため熱の放散の低下は別段問題と はならない。Since the periphery of the geared motor 2 is covered by the storage portion 3, it is difficult for heat generated by the operation of the motor to be dissipated to the outside, but in the case of a configuration in which the internal weight lifting mechanism of the weighing device is operated. Since the operating time of a motor is about 5 to 6 seconds once, and the calibration work itself is not a frequent work, the reduction of heat dissipation is not a particular problem.
【0024】 図2は本考案の別の実施例を示す。この実施例では据付部材1の収納部3の内 壁に対して溝3cが形成されている。この溝3cは収納部3の軸心方向に対して ほぼ平行に多数形成されており、収納部3にギヤドモータ2が収納配置されるこ とによりこの溝3cはギヤドモータ2の外部周壁と収納部3の内周壁との間に形 成された空間部となる。FIG. 2 shows another embodiment of the present invention. In this embodiment, a groove 3c is formed on the inner wall of the storage portion 3 of the installation member 1. A large number of the grooves 3c are formed substantially parallel to the axial direction of the housing portion 3. When the geared motor 2 is housed in the housing portion 3, the grooves 3c are formed in the housing 3 and the outer peripheral wall of the geared motor 2. It is a space formed between the inner wall of the and.
【0025】 前記溝3cは収納部3aに対してギヤドモータ2を収納し易くする機能を有す る。またこの溝3cはギヤドモータ2を長時間作動させたり、または頻繁に作動 させる場合でもモータから発生した熱はこの空間部を通って外部に効果的に放出 され、モータの過熱を抑制できる。The groove 3c has a function of making it easier to store the geared motor 2 in the storage portion 3a. Further, even if the geared motor 2 is operated for a long time or is frequently operated, the groove 3c effectively releases the heat generated from the motor to the outside through the space portion, thereby suppressing overheating of the motor.
【0026】 次に、据付部材1の形成材料、例えばゴム材料に対して透磁性を有する金属材 料、例えば銅粉や鉄粉を添加し、この透磁性金属材料が添加された材料により形 成された据付部材1を透磁性とする。据付部材1がこのような材料により形成さ れると、例えば電磁平衡式の秤量装置においては、ギヤドモータ2により形成さ れる磁界によって秤量装置の電磁部が悪影響を受けるような事態を防止すること ができる。Next, a metal material having magnetic permeability, for example, copper powder or iron powder, is added to the forming material of the mounting member 1, for example, a rubber material, and the mounting member 1 is formed of the material to which the magnetically permeable metal material is added. The installed mounting member 1 is made magnetically permeable. When the mounting member 1 is made of such a material, for example, in an electromagnetic balance type weighing device, it is possible to prevent a situation where the electromagnetic portion of the weighing device is adversely affected by the magnetic field formed by the geared motor 2. ..
【0027】 なお、据付部材1に収納される対象をギヤドモータを例に説明したが、もとよ りこれに限定する趣旨ではなく、減速部分を持たない通常のモータに対しても当 然使用可能である。It should be noted that the object housed in the installation member 1 has been described by taking a geared motor as an example, but the present invention is not intended to be limited to this, and can also be applied to a normal motor having no deceleration portion.

本考案は以上具体的に説明した如く、モータはゴムまたはこれと同効の可撓性 を有する材料により覆われかつ支持されるので、モータが発生する振動や作動音 の大半はこの据付部材に吸収され、モータの発生する振動が他の機構に悪影響を 与えるのを防止でき、しかも機構操作が静粛に行える。 As described in detail above, the present invention covers and supports the motor with rubber or a flexible material having the same effect as that of the present invention. Therefore, most of the vibrations and operating noises generated by the motor are caused by this mounting member. It is possible to prevent the vibration generated by the motor from being absorbed and adversely affecting other mechanisms, and moreover, the mechanism can be operated quietly.
【0029】 また据付部材に収納されたモータとこのモータに接続する機構との取り合わせ の変位を、可撓性を有する据付部材が直接修正するので、モータとこのモータに 接続する軸との間に変位吸収用の大型カップリングを取り付ける必要がなくなり 、このモータにより作動する機構の配置や、この機構に対して取り付ける部材の 取り付け位置設定の自由度を高めることが可能となる。Further, since the displacement of the combination of the motor housed in the installation member and the mechanism connected to this motor is directly corrected by the flexible installation member, the displacement between the motor and the shaft connected to this motor is corrected. Since it is not necessary to attach a large coupling for displacement absorption, it is possible to increase the degree of freedom in the arrangement of the mechanism operated by this motor and the setting of the attachment position of the member attached to this mechanism.
