Description
【０００１】[0001]
本考案は、着脱自在な載せ皿を設けた秤に関する。 The present invention relates to a scale provided with a detachable plate.
【０００２】[0002]
重量を測定する対象物を上面に載置する載せ皿を装置本体より着脱自在にして いる秤が従来よりある。このような秤は、載せ皿を装置本体から取り外してメン テナンス等することができる。そして、載せ皿を着脱する構造としては、重量の 測定を行なう重量検出部に皿受けフレームを固定的に取り付け、この皿受けフレ ームに前記載せ皿を着脱自在に取り付けることが行なわれている。さらに、この ような構造では、前記載せ皿の下面に先端側が根元側に対して細い段付軸を複数 立設し、この段付軸の先端側を前記皿受けフレームに形成されている取付孔に抜 き差し自在に挿入させ、前記支持フレーム上に載置するようにして前記載せ皿を 前記支持フレームに取り付けている。 2. Description of the Related Art Conventionally, there is a scale in which a placing plate on which an object whose weight is to be measured is placed is attached to and detached from the apparatus body. In such a scale, the loading tray can be removed from the main body of the apparatus for maintenance and the like. As a structure for attaching and detaching the placing tray, a dish receiving frame is fixedly attached to a weight detecting unit for measuring the weight, and the placing tray is detachably attached to the dish receiving frame. . Further, in such a structure, a plurality of stepped shafts whose tip end side is thin with respect to the base side are erected on the lower surface of the placing tray, and the tip end side of the stepped shafts is attached to the dish receiving frame. The mounting tray is attached to the support frame so that it can be inserted into and removed from the support frame and placed on the support frame.
【０００３】[0003]
上述のように段付軸を支持フレームに形成されている取付孔に挿入させて載せ 皿を皿受けフレームに取り付ける構造の秤では、載せ皿を皿受けフレームに取り 付ける際に皿受けフレームに形成されている取付孔と段付軸との位置合わせが難 しく、取り付けが難しいという欠点がある。 As described above, in a scale with a structure in which the stepped shaft is inserted into the mounting hole formed in the support frame to mount the plate on the pan receiving frame, the plate is formed on the pan receiving frame when the pan is mounted on the pan receiving frame. It is difficult to align the mounting hole with the stepped shaft, which makes mounting difficult.
【０００４】[0004]
重量を測定する対象物を上面に載置する載せ皿と、重量検出部に接続されると 共に前記載せ皿を下方より支持する皿受けフレームとを設け、下方に突出した柱 状の脚部を前記載せ皿の周縁部に少なくとも３個形成し、この脚部を前記皿受け フレームに形成されている取付孔に抜き差し自在に挿入させて前記載せ皿を前記 皿受けフレームに着脱自在に取り付けた秤において、前記脚部の先端に前記取付 孔への挿入時に案内面となる面取り部を前記載せ皿の内側に向けて形成した。 A platform for placing an object to be weighed on the upper surface and a dish receiving frame for supporting the platform from below while being connected to the weight detection unit are provided, and column-shaped legs protruding downward are provided. At least three scales are formed on the peripheral edge of the tray and the legs are detachably inserted into the mounting holes formed in the tray receiving frame so that the tray is removably attached to the tray receiving frame. In the above, a chamfered portion, which serves as a guide surface when inserted into the mounting hole, is formed at the tip of the leg portion so as to face the inside of the placing tray.
【０００５】[0005]
脚部を皿受けフレームに形成されている取付孔に挿入させる際に、脚部の先端 に形成されている面取り部がこの脚部を取付孔に案内するように作用するので、 脚部を取付孔にスムースに挿入させることができる。 When inserting the leg into the mounting hole formed in the dish receiving frame, the chamfered part formed at the tip of the leg acts to guide this leg into the mounting hole. It can be inserted smoothly into the hole.
【０００６】 ところで、この載せ皿は偏荷重を受けると回動して偏荷重を受けている側と反 対側の端部が浮き上がり、この端部に設けられている脚部が載せ皿の回動につれ て皿受けフレームに形成されている取付孔から抜ける。しかし、載せ皿の回動に つれて脚部が傾いてこの脚部の載せ皿の外側（以下「脚部の外側」と呼ぶ）が取 付孔に掛るように当接するので、脚部が完全に取付孔から抜ける前に載せ皿の回 動が停止される。By the way, when a load is applied to the mounting plate, the plate rotates to rotate, and the end portion on the side opposite to the side receiving the unbalanced load is lifted up, and the legs provided at this end rotate the loading plate. As it moves, it comes out from the mounting hole formed in the pan receiving frame. However, since the legs are tilted as the tray is rotated and the outside of the legs of the legs (hereinafter referred to as the “outside of the legs”) abut on the mounting holes, the legs are completely The rotation of the loading tray is stopped before it comes out of the mounting hole.
【０００７】[0007]
本考案の一実施例を図面に基づいて説明する。本実施例の秤は、郵便物の重量 を測定し、この重量から郵便料金を算出する電子料金秤である。そして、この算 出された料金を表示するものである。まず、外観的には図２に示すように本体ケ ース１の上面手前側に料金や重量を表示する表示部２と共に操作キー３が設けら れ、その後方に図示しない測定物を載置する長方形の載せ皿４が設けられている 。 An embodiment of the present invention will be described with reference to the drawings. The balance of the present embodiment is an electronic charge balance that measures the weight of mail and calculates the postage from this weight. Then, the calculated fee is displayed. First, as shown in FIG. 2, an operation key 3 is provided on the front side of the upper surface of the main body case 1 together with a display section 2 for displaying charges and weight, and an object to be measured (not shown) is placed behind it. A rectangular mounting plate 4 is provided.
【０００８】 つぎに、内部的には、図１及び図３に示すように、重量検出部である片持ち梁 状のロードセル５が前記本体ケース１の上面に沿わせて設けられており、このロ ードセル５の一端が前記本体ケース１にねじ止され、このロードセル５の自由端 である他端に前記本体ケース１の上面に沿わせた平板状の皿受けフレーム６がね じ止されている。そして、この電子料金秤は、前記皿受けフレーム６に前記載せ 皿４がその下方に突設されている脚部である段付軸７で取り付けられ、前記ロー ドセル５の自由端で前記載せ皿４を支持する構造とされている。Next, internally, as shown in FIGS. 1 and 3, a cantilever-shaped load cell 5 as a weight detection unit is provided along the upper surface of the main body case 1. One end of the load cell 5 is screwed to the main body case 1, and a flat plate receiving frame 6 along the upper surface of the main body case 1 is screwed to the other end which is a free end of the load cell 5. . This electronic toll scale is attached to the dish receiving frame 6 by a stepped shaft 7 which is a leg portion projecting downward from the dish 4, and the free tray of the load cell 5 serves as the dish. It is structured to support 4.
【０００９】 前記載せ皿４は、上述の段付軸７が図３に示すように４隅にそれぞれ設けられ ている。この段付軸７は先端側が細く根元側が太くされており、この先端には面 取り部７ａが形成されている。この面取り部７ａは前記載せ皿４の内側に向けて 、すなわち本実施例では前記載せ皿４の長手方向に互いに対向している段付軸７ の互いに対向する側にだけ形成されている。The loading tray 4 is provided with the stepped shafts 7 at four corners as shown in FIG. The stepped shaft 7 has a thin tip side and a thick root side, and a chamfer 7a is formed at the tip. The chamfered portion 7a is formed only toward the inner side of the loading tray 4, that is, in the present embodiment, only on the opposite sides of the stepped shafts 7 facing each other in the longitudinal direction of the loading tray 4.
【００１０】 そして、前記皿受けフレーム６には、前記載せ皿４の前記段付軸７にそれぞれ 対向させて取付孔８が形成されている。この取付孔８にはフランジ９ａ付きのゴ ムブッシュ９がはめこまれており、このゴムブッシュ９を介して前記段付軸７の 先端側が前記取付孔８に抜き差し自在に挿入されると共にこのゴムブッシュ９の フランジ９ａを介して前記段付軸７の段部７ｂが前記皿受けフレーム６に当接さ れて、この皿受けフレーム６上に載置するようにして前記載せ皿４が前記皿受け フレーム６に取り付けられている。The dish receiving frame 6 has mounting holes 8 formed so as to face the stepped shafts 7 of the loading tray 4, respectively. A rubber bush 9 with a flange 9a is fitted in the mounting hole 8, and the tip end side of the stepped shaft 7 is inserted into the mounting hole 8 via the rubber bush 9 and is inserted and removed. The stepped portion 7b of the stepped shaft 7 is brought into contact with the dish receiving frame 6 via the flange 9a of the plate 9 so that the dish receiving frame 6 is placed on the dish receiving frame 6 and the dish 4 is placed on the dish receiving frame 6. It is attached to the frame 6.
【００１１】 このような構成において、この電子料金秤は、載せ皿４上に測定物を載置する と、この載せ皿４を支持しているロードセル５に歪が生じ、この歪に基づいて測 定物の重量が算出されると共にこの重量とキー入力された情報とから測定物の料 金が算出されて、その重量と料金とが表示部２に表示される。In such a structure, when the object to be measured is placed on the placing plate 4, the electronic toll balance is distorted in the load cell 5 supporting the placing plate 4, and the load cell 5 is measured based on the strain. The weight of the fixed object is calculated, and the fee of the object to be measured is calculated from the weight and the information input by the key, and the weight and the fee are displayed on the display unit 2.
【００１２】 ここで、この電子料金秤は、清掃等の為に、載せ皿４を上方に引き上げて装置 本体より取り外すことができる。そして、この載せ皿４を再び装置本体に取り付 けるには、載せ皿４の段付軸７の先端と皿受けフレーム６に形成されている取付 孔８との位置合わせをし、段付軸７を取付孔８に挿入させて載せ皿４を皿受けフ レーム６に取り付ける。このとき、本実施例では、段付軸７の先端に形成されて いる面取り部７ａが段付軸７の先端を取付孔８に案内するように作用するので段 付軸７の先端と取付孔８との位置合わせがある程度狂っていてもスムースに段付 軸７の先端を取付孔８に挿入させることができ、容易に載せ皿４を装置本体に取 り付けることができる。Here, this electronic fee scale can be removed from the main body of the apparatus by pulling up the loading tray 4 for cleaning or the like. Then, in order to attach the mounting plate 4 to the apparatus body again, the tip of the stepped shaft 7 of the mounting plate 4 and the mounting hole 8 formed in the plate receiving frame 6 are aligned and the stepped shaft 4 is attached. 7 is inserted into the mounting hole 8 and the placing tray 4 is attached to the tray receiving frame 6. At this time, in this embodiment, the chamfered portion 7a formed at the tip of the stepped shaft 7 acts so as to guide the tip of the stepped shaft 7 to the mounting hole 8, so that the tip of the stepped shaft 7 and the mounting hole 7 Even if the alignment with 8 is misaligned to some extent, the tip of the stepped shaft 7 can be smoothly inserted into the mounting hole 8, and the loading tray 4 can be easily attached to the apparatus body.
【００１３】 また、この載せ皿４は、図４に例示するように段付軸７が設けられている位置 よりも外側の一端部に偏荷重Ａを受けると、この一端部付近に設けられている段 付軸７を支点として回動し、他端部が浮き上がり、この他端部に取り付けられて いる段付軸７が載せ皿４の回動につれて皿受けフレーム６に形成されている取付 孔８から抜ける。しかし、載せ皿４の回動につれて段付軸７が傾いてこの段付軸 ７の載せ皿４の外側（以下「段付軸７の外側」と呼ぶ）が皿受けフレーム６の取 付孔８に掛るように当接するので、段付軸７が完全に取付孔８から抜ける前に載 せ皿４の回動が停止される。Further, as shown in FIG. 4, the placing plate 4 is provided near the one end when an unbalanced load A is applied to the one end outside the position where the stepped shaft 7 is provided. Rotating with the stepped shaft 7 present as a fulcrum, the other end floats up, and the stepped shaft 7 attached to this other end is formed in the plate receiving frame 6 as the plate 4 rotates. Exit from 8. However, as the plate 4 rotates, the stepped shaft 7 tilts so that the outside of the plate 4 of the stepped shaft 7 (hereinafter referred to as “the outside of the stepped shaft 7”) is attached to the mounting hole 8 of the plate receiving frame 6. Since the stepped shaft 7 is completely abutted from the mounting hole 8, the rotation of the mounting tray 4 is stopped.
【００１４】 ここで、段付軸７の長さが短いと、段付軸７が取付孔８から抜けやすいので、 段付軸７にはある程度の長さが必要である。ところが、段付軸７の先端に面取り 部を設けてしまうと段付軸７の実質の長さが短くなってしまう。Here, when the length of the stepped shaft 7 is short, the stepped shaft 7 is likely to come out of the mounting hole 8. Therefore, the stepped shaft 7 needs to have a certain length. However, if the chamfered portion is provided at the tip of the stepped shaft 7, the actual length of the stepped shaft 7 becomes short.
【００１５】 本実施例では、段付軸７の面取り部７ａを載せ皿４の内側に向けて形成するよ うにしたので、載せ皿４の回動時に取付孔８に掛ることになる段付軸７の外側の 長さを確保することができ、載せ皿４に偏荷重が加わった際に、段付軸７の先端 の全周に面取り部を形成したものに比べ段付軸７が取付孔８から抜けにくい。In this embodiment, since the chamfered portion 7a of the stepped shaft 7 is formed so as to face the inside of the mounting tray 4, the stepped shaft to be hooked on the mounting hole 8 when the mounting tray 4 is rotated. The outer length of the stepped shaft 7 can be secured, and when an unbalanced load is applied to the placing plate 4, the stepped shaft 7 has a mounting hole as compared with the stepped shaft 7 having a chamfered portion formed all around the tip. It is hard to get out of 8.
【００１６】 また、このように、段付軸７の面取り部７ａを載せ皿４の内側に向けて形成す ることは、段付軸７の段部７ｂより下方の長さが短いときに特に有効である。In addition, forming the chamfered portion 7a of the stepped shaft 7 toward the inside of the tray 4 as described above is particularly effective when the length of the stepped shaft 7 below the stepped portion 7b is short. It is valid.
【００１７】 なお、図５に示すように載せ皿４の短軸方向に互いに対向している段付軸７の 互いに対向する側にだけ面取り部７ａを形成するようにしても良く、さらに、載 せ皿４の対角方向に互いに対向している段付軸７の互いに対向する側にだけ面取 り部７ａを形成するようにしても良い。また、面取り部を形成する位置は、必ず しも互いに対向している側に限定されるものではなく、載せ皿４の内側であれば 良い。As shown in FIG. 5, the chamfered portions 7a may be formed only on the opposite sides of the stepped shafts 7 that face each other in the minor axis direction of the placing plate 4, and further, The chamfered portions 7a may be formed only on the opposite sides of the stepped shafts 7 that are diagonally opposite to each other of the tray 4. Further, the position where the chamfered portion is formed is not necessarily limited to the side where the chamfered portions face each other, and may be inside the loading tray 4.
【００１８】[0018]
【考案の効果】 本考案は上述のように、脚部の先端に面取り部を設けたので、脚部を皿受けフ レームに形成されている取付孔に挿入させる際に、面取り部が脚部を取付孔に案 内するように作用し、脚部を取付孔にスムースに挿入させることができ、さらに 、載せ皿の内側に向けてその面取り部を形成したので、偏荷重によって載せ皿が 回動したときに取付孔に掛ることになる脚部の外側の長さを確保することができ 、載せ皿に偏荷重が加わった際に、脚部の先端の全周に面取り部を形成したもの に比べ脚部が取付孔から抜けにくい等の効果を有する。As described above, according to the present invention, the chamfered portion is provided at the tip of the leg portion. Therefore, when the leg portion is inserted into the mounting hole formed in the dish receiving frame, the chamfered portion is formed. The leg part can be smoothly inserted into the mounting hole, and the chamfered part is formed toward the inside of the mounting plate so that the mounting plate can rotate due to an unbalanced load. It is possible to secure the outside length of the leg that will be caught in the mounting hole when moving, and the chamfered part is formed all around the tip of the leg when an unbalanced load is applied to the placing pan. Compared with the above, it has an effect that the leg part is hard to come off from the mounting hole.
