Description

本発明は、組合せ秤におけるホッパに関するものであって、詳しくはホッパにおける被計量物のゲートへの噛み込みによる過負荷を防止できるようにした組合せ秤用ホッパに関するものである。   The present invention relates to a hopper in a combination weigher, and more particularly to a hopper for a combination weigher that can prevent overload due to biting of an object to be weighed in a hopper.

従来、組合せ秤では、例えば図４の概要図で示されるように、頂部に配置されたメインフィーダ３７（分散フィーダ）に供給された被計量物４０が、そのメインフィーダ３７の周囲に配置された複数のリニアフィーダ３６に分配され、その各リニアフィーダ３６によって対応する位置に配される供給ホッパ１に搬送され、次いで計量ホッパ３５に送られて制御装置３８からの指令によって所要の計量ホッパ３５から集合シュート３９に放出され、包装装置に供給されるようになされている。   Conventionally, in the combination weigher, for example, as shown in the schematic diagram of FIG. 4, the objects to be weighed 40 supplied to the main feeder 37 (dispersing feeder) arranged at the top are arranged around the main feeder 37. It is distributed to a plurality of linear feeders 36 and conveyed to the supply hopper 1 disposed at the corresponding position by each linear feeder 36, then sent to the weighing hopper 35 and from the required weighing hopper 35 by a command from the control device 38. It is discharged to the collecting chute 39 and supplied to the packaging device.

ところで、分散フィーダ３７からリニアフィーダ３６に供給された被計量物４０は、そのリニアフィーダ３６によって振動を与えられて搬送される。そこで、硬めで長物（例えば、ペットフードなど）の被計量物は予期しないときに搬送され、供給ホッパ１のゲートに噛み込むことがある。例えば、被計量物４０がリニアフィーダ３６のフィードパン３６ａの末端に半分以下の状態で食み出して停止しているときに、リニアフィーダ３６以外の振動で被計量物４０が供給ホッパ１に落下し、閉じかけの状態にある供給ホッパ１のゲートに噛み込むことがある。被計量物４０がホッパのゲートに噛み込むと、その被計量物４０が破損することがあり、商品価値を落すことになる。また、ゲートの駆動装置のトグル機構あるいは駆動するモータが過負荷になり、消耗を早めることになる。このような噛み込みの対策として、ゲートの先端部に合成ゴムなどによる緩衝部材を取り付け、ゲート間の隙間を塞ぐようにすることが一般的に実施されている。   By the way, the object to be weighed 40 supplied from the dispersion feeder 37 to the linear feeder 36 is conveyed by being vibrated by the linear feeder 36. Therefore, a to-be-measured object that is hard and long (for example, pet food, etc.) may be conveyed at an unexpected time and bite into the gate of the supply hopper 1. For example, when the object to be weighed out is stopped at the end of the feed pan 36a of the linear feeder 36 in a state of less than half, the object to be weighed 40 drops to the supply hopper 1 due to vibrations other than the linear feeder 36. In some cases, the gate of the supply hopper 1 that is in the closed state may be bitten. When the object to be weighed 40 bites into the gate of the hopper, the object to be weighed 40 may be damaged, and the commercial value will be reduced. In addition, the toggle mechanism of the gate drive device or the motor to be driven becomes overloaded, resulting in accelerated wear. As a countermeasure against such biting, generally, a buffer member made of synthetic rubber or the like is attached to the tip of the gate to close the gap between the gates.

このほか、被計量物の形状と性状に合わせて、ホッパのゲートに緩衝部材を使用せずにホッパ構造に特長を持たせたものとしては特許文献１によって知られるものがある。この特許文献１にて開示されるものでは、ホッパの排出口開閉用のゲート板にロック機構を付帯させ、落下してくる被計量物の衝撃でゲートが開かないようにロックバーをホッパに取付けるように構成されている。また、本出願人の先発明に係る振分け機能を備えた両開き式のゲート付きホッパが特許文献２によって知られている。この両開き式のゲート付きホッパは、補助ホッパの区分された区画に対して計量された物品を振分けて供給することができるように、相互に一方のゲート板を開くと対向する片方の区分に物品が流れ落ちるように、両ゲート板の先端に工夫を加えた構成のものである。   In addition to this, there is one known from Patent Document 1 in which a hopper structure is given a characteristic without using a buffer member in the hopper gate in accordance with the shape and properties of the object to be weighed. In the technique disclosed in Patent Document 1, a lock mechanism is attached to a gate plate for opening and closing a discharge opening of a hopper, and a lock bar is attached to the hopper so that the gate does not open due to an impact of a falling object to be weighed. It is configured as follows. Further, Patent Document 2 discloses a double-open gated hopper having a distribution function according to the prior invention of the present applicant. This double-opened gated hopper is designed to distribute the articles weighed to the divided sections of the auxiliary hopper so that the articles are placed in one section facing each other when one gate plate is opened. This is a configuration in which the tips of both gate plates are devised so as to flow down.

前記先行技術におけるホッパゲートに合成ゴムなどの緩衝部材を取付けて隙間を塞ぐ構成にあっては、ゲートが閉じる直前に被計量物がゲートに噛み込んだ場合、その緩衝部材が弾性変形してゲートの開閉機構を構成するトグルあるいはモータに過負荷が作用しないようにされているが、長期にわたり使用していると、その緩衝部材が劣化して疲労破壊を起こし、一部が切断されて異物となって取扱われる物品に混入するという問題がある。また、ホッパを洗浄する場合に緩衝部材が取付けられていると邪魔になって清浄作業を妨げるという問題点がある。また、前記特許文献１あるいは特許文献２によるホッパのゲートであっても、予期せぬタイミングで被計量物（物品）がホッパ内に転げ落ちるとホッパのゲートに物品が噛み込み、ゲートを駆動するモータが脱調するという問題が生じる。   In the prior art, a buffer member such as synthetic rubber is attached to the hopper gate to close the gap, and when the object to be weighed in the gate immediately before the gate closes, the buffer member elastically deforms and the gate Although the overload does not act on the toggle or motor that constitutes the opening and closing mechanism, if it is used for a long time, the buffer member will deteriorate and cause fatigue failure, and part will be cut and become foreign matter There is a problem that it is mixed into articles handled in the future. In addition, when the hopper is cleaned, there is a problem that if the buffer member is attached, the cleaning operation is hindered. Further, even in the hopper gate according to Patent Document 1 or Patent Document 2, when an object to be weighed (article) falls into the hopper at an unexpected timing, the article bites into the hopper gate and drives the gate. The problem of stepping out.

本発明はこのような問題点を解決して、不測の事態でホッパ内に物品が落下してもゲートを駆動する機構や動力部に過負荷を与えることなく作動できる組合せ秤用ホッパを提供することを目的とするものである。   The present invention solves such problems, and provides a combination weigher hopper that can operate without overloading a mechanism or a power unit for driving a gate even if an article falls into the hopper in an unexpected situation. It is for the purpose.

前記目的を達成するために、本発明による組合せ秤用ホッパは、
アクチュエータにより作動する両開きゲートを備えた組合せ秤用ホッパであって、
前記両開きゲートは、その一方のゲート板が動力により駆動されるゲート開閉機構に繋がれて基端部をホッパ本体の両側部に枢軸支され、他方のゲート板は前記一方のゲート板に対して外側を囲う構造で基端部をホッパ本体両側部に枢軸支されるとともに、外側部でホッパ本体側に一端を取着される引張ばねの他端を繋がれて常時閉じ方向に引寄せられて装着されていることを特徴とするものである（第１発明）。 In order to achieve the above object, a hopper for a combination weigher according to the present invention comprises:
A hopper for a combination weigher equipped with a double gate operated by an actuator,
The double gate is connected to a gate opening / closing mechanism in which one gate plate is driven by power, and the base end portion is pivotally supported on both sides of the hopper body, and the other gate plate is connected to the one gate plate. With the structure that surrounds the outside, the base end is pivotally supported on both sides of the hopper body, and the other end of the tension spring that is attached to the hopper body at the outside is connected to the hopper body so that it is always drawn in the closing direction. It is characterized by being mounted (first invention).

前記発明において、前記ゲート開閉機構により操作されるゲート板の先端部には、断面鉤形に屈曲形成された受け板が、屈曲部をゲート板の内面より下側にして、対向するゲート板の先端に平行して全幅方向に突出形成されているのがよい（第２発明）。   In the present invention, a receiving plate bent in a bowl shape is formed at the tip of the gate plate operated by the gate opening / closing mechanism, with the bent portion being below the inner surface of the gate plate. It is good to project in the full width direction parallel to the tip (second invention).

本発明によれば、ホッパ本体に付設される両開きゲートの両ゲート板が、その一方のゲート板のみをゲート開閉機構によって開閉動作するようにされ、他方のゲート板にはホッパ本体に一端を取着される引張ばねを連結した構成であるから、ホッパから物品が排出されてゲートを閉じるときに遅れて落下してきた物品がゲートに噛み込んだ場合でも、ゲート開閉機構によって積極的に閉じ方向に操作される一方のゲート板に対し、他方のゲート板は引張ばねにて閉じ方向に保持されているだけであるから保持している引張ばねが伸びてこの他方のゲートが開く方向に動作する。その結果、前記一方のゲートを操作するゲート開閉機構に掛かる過負荷が軽減され、そのゲート開閉機構を構成するトグルリンクや駆動するアクチュエータに支障を来たすことがないという効果を奏するのである。そして、従来のように、ゲートの先端に緩衝部材を設ける必要がないので、異物の混入問題を起こすことがなく、また、ホッパの洗浄に際して障害物（緩衝部材）がないのでその洗浄が容易になるという利点がある。   According to the present invention, the gate plates of the double-open gates attached to the hopper body are configured to open and close only one of the gate plates by the gate opening / closing mechanism, and one end of the hopper body is attached to the other gate plate. Since the tension spring to be worn is connected, even when the article is discharged from the hopper and dropped late when the gate is closed, the gate opening / closing mechanism positively closes it in the closing direction. With respect to one gate plate to be operated, the other gate plate is only held in the closing direction by a tension spring, so that the holding tension spring extends and the other gate opens. As a result, the overload applied to the gate opening / closing mechanism for operating the one gate is reduced, and the toggle link and the driving actuator constituting the gate opening / closing mechanism are not hindered. And since there is no need to provide a buffer member at the tip of the gate as in the prior art, there is no problem of foreign matter mixing, and there is no obstacle (buffer member) when cleaning the hopper, so that cleaning is easy. There is an advantage of becoming.

また、前記第２発明の構成を採用することにより、ゲート開閉機構で操作される側のゲート板先端に設けられた受け板が、前記他方のゲート板（従動側のゲート板）の先端に平行して段差を付けて配されているので、その従動側のゲート板が噛み込み物品によって押し開かれても直ちに受止めて物品を直接落下させずに、かつせん断力が作用せずに受止めて物品を損傷させることがないという効果が得られる。   Further, by adopting the configuration of the second invention, the receiving plate provided at the front end of the gate plate operated by the gate opening / closing mechanism is parallel to the front end of the other gate plate (driven side gate plate). Therefore, even if the gate plate on the driven side is pushed and opened by the biting article, it is immediately received and the article is not dropped directly, and the shearing force does not act. Thus, the effect of not damaging the article can be obtained.

そして、前記ゲート開閉機構にて操作されるゲート板の先端に受け板を設けておけば、ゲートに物品が噛み込んで前記他方のゲート板が押し開かれる状態となっても、そのまま物品が落下せずに受止められ、例えば供給ホッパにおけるゲートの場合、この供給ホッパから計量済みの計量ホッパ内に遅れて物品が落下するのを防止できるという効果を奏する。   If a receiving plate is provided at the tip of the gate plate operated by the gate opening / closing mechanism, the article will fall as it is even if the article is caught in the gate and the other gate plate is pushed open. For example, in the case of a gate in the supply hopper, there is an effect that it is possible to prevent the article from falling late from the supply hopper into the weighed measurement hopper.

次に、本発明による組合せ秤用ホッパの具体的な実施の形態について、図面を参照しつつ説明する。   Next, specific embodiments of the combination weigher hopper according to the present invention will be described with reference to the drawings.

FIG. 2 is a diagram showing a driving unit of the gate opening / closing mechanism, FIG. 3 shows a mode of gate opening / closing of the hopper, (a) is a diagram when the gate is opened, and (b) is an article on the gate. FIG. 4 shows a schematic diagram of a combination weigher in which the present invention is implemented.

この実施形態のホッパは、組合せ秤の供給ホッパに適用したものである。この供給ホッパ１は、角筒形に形成されるホッパ本体２と、このホッパ本体２の下部に付設される両開き式のゲート３およびゲート開閉機構１０とで構成されている。   The hopper of this embodiment is applied to a supply hopper of a combination weigher. The supply hopper 1 includes a hopper body 2 formed in a rectangular tube shape, and a double-opening gate 3 and a gate opening / closing mechanism 10 attached to a lower portion of the hopper body 2.

前記両開き式のゲート３は、所要容積のホッパ本体２の下部にて図上逆三角状に形成された側板２ａ（片側のみ表示、以下同様）にてなるホッパ本体２の底部を、その側板２ａの縁部に沿って左右両側から一対のゲート板４，５で閉じ合うようにされており、その一方のゲート板４はゲート開閉機構１０によって開閉するようにされ、他方のゲート板５は後述する引張ばね２２によって常時閉じ方向に保持される構成である。   The double-open gate 3 has a bottom portion of a hopper body 2 formed of a side plate 2a (only one side is shown, the same applies hereinafter) formed in an inverted triangular shape in the lower part of the hopper body 2 having a required volume. A pair of gate plates 4 and 5 is closed from both the left and right sides along the edge of the gate. One gate plate 4 is opened and closed by a gate opening / closing mechanism 10, and the other gate plate 5 is described later. The tension spring 22 is always held in the closing direction.

前記一方のゲート板４（以下、説明の都合上「主動ゲート板４」という）は、前記ホッパ本体２の側板２ａにおける一方の縁部２ａ′に沿って底部を閉じるように配される底板４ａおよびこの底板４ａの両側で上向きに屈曲して前記ホッパ本体２の逆三角状の側板２ａ部を囲うように形成された側面板４ｂ（片側のみ表示、以下同様）とを備えている。そして、前記側面板４ｂの上端部がホッパ本体２の両側面の上下方向中間部に付設された枢支軸６により枢支されて回動自在に設けられている。この主動ゲート板４には、その底板４ａの外面上部寄り位置にブラケット７が取付けられ、このブラケット７に前記ゲート開閉機構１０のリンク１１の一端が軸７ａにて回動自在に連結されている。   The one gate plate 4 (hereinafter referred to as “main drive gate plate 4” for convenience of explanation) is arranged such that the bottom plate 4a is disposed so as to close the bottom along one edge 2a ′ of the side plate 2a of the hopper body 2. And a side plate 4b (displayed only on one side, the same applies hereinafter) formed so as to be bent upward on both sides of the bottom plate 4a and to surround the inverted triangular side plate 2a portion of the hopper body 2. And the upper end part of the said side surface board 4b is pivotally supported by the pivot shaft 6 attached to the up-down direction intermediate part of the both sides | surfaces of the hopper main body 2, and is provided rotatably. A bracket 7 is attached to the main driving gate plate 4 at a position closer to the upper surface of the bottom plate 4a, and one end of the link 11 of the gate opening / closing mechanism 10 is rotatably connected to the bracket 7 by a shaft 7a. .

前記ゲート開閉機構１０は、ホッパ本体２の側部に取付いてそのまま側方に延長突設されている支持部材８に支持された軸受９にて枢支軸１２が支承され、前記主動ゲート板４の底板４ａと平行して前記枢支軸１２に基端部を取着される回動リンク１４と、前記主動ゲート板４に付設のブラケット７に軸７ａを介して連結されるリンク１１と、前記回動リンク１４の基部上にその枢支軸１２と平行して取付く操作軸ピン１５と、この操作軸ピン１５に切込み溝１６ａ係合して回動操作をする二股形状の搖動リンク１６（図２参照）およびその搖動リンク１６を所要回転角反復回動させる図示されないアクチュエータ１８（具体例としてモータが用いられる）とで構成されている。前記回動リンク１４とリンク１１とは連結ピン１７により回動自在に連結されている。このゲート開閉機構１０は、前記搖動リンク１６を所要回転角回動させると操作軸ピン１５を介して回動リンク１４によりその先端に繋がるリンク１１を増幅回動変位させ、主動ゲート板４を閉鎖位置から真下に移動してホッパ本体２内を開放するように、各リンク１１，１４の変位回動角が設定されている。   The gate opening / closing mechanism 10 is mounted on a side portion of the hopper body 2, and a pivot shaft 12 is supported by a bearing 9 supported by a support member 8 that extends and projects sideways as it is. A pivot link 14 attached to the pivot shaft 12 in parallel with the bottom plate 4a, and a link 11 connected to the bracket 7 attached to the main gate plate 4 via a shaft 7a; An operation shaft pin 15 mounted on the base portion of the rotation link 14 in parallel with the pivot shaft 12, and a bifurcated peristaltic link 16 engaged with the operation shaft pin 15 and engaged with the cut groove 16a for rotation operation. (See FIG. 2) and an actuator 18 (a motor is used as a specific example) (not shown) that repeatedly rotates the peristaltic link 16 at a required rotation angle. The rotation link 14 and the link 11 are rotatably connected by a connecting pin 17. When the peristaltic link 16 is rotated at a required rotation angle, the gate opening / closing mechanism 10 amplifies and displaces the link 11 connected to the tip of the peristaltic link 14 via the operation shaft pin 15 and closes the main gate plate 4. The displacement rotation angles of the links 11 and 14 are set so that the hopper main body 2 is opened from the position and opened inside.

一方、前記他方のゲート板５（以下、説明の都合上「従動ゲート板５」という）は、前記主動ゲート板４と同様に底板５ａがホッパ本体２の側板２ａにおける他方の縁部２ａ″に沿って底部を閉じるように配される底板５ａと、この底板５ａの両側で上向きに屈曲されて前記ホッパ本体２の逆三角状の側板部２ａを囲うとともに、前記主動ゲート板４の側面板４ｂの一部も囲うように形成された側面板５ｂ（片側のみ表示、以下同様）とを備えている。そして、前記側面板５ｂの上端部をホッパ本体２の両側面で上下方向中間部に付設された枢支軸６′により枢支されて回動自在に設けられている。この従動ゲート板５は、前記ホッパ本体２の側面に付設される補強支持板８ａに突設される連結軸ピン２１に一端を係着された引張ばね２２の他端と側面板５ｂの上部で繋がれ、この引張ばね２２によって常時ホッパ本体２の側板２ａにおける他方の縁部２ａ″に沿って底部を閉じるように形成されている。   On the other hand, the other gate plate 5 (hereinafter referred to as “driven gate plate 5” for convenience of explanation) has a bottom plate 5a formed on the other edge 2a ″ of the side plate 2a of the hopper body 2 in the same manner as the main drive gate plate 4. And a side plate 4b of the main gate plate 4 while being bent upward on both sides of the bottom plate 5a to surround the inverted triangular side plate 2a of the hopper body 2. The side plate 5b is formed so as to surround a part of the side plate 5b (only one side is displayed, the same applies hereinafter), and the upper end of the side plate 5b is attached to the middle part in the vertical direction on both side surfaces of the hopper body 2. The driven gate plate 5 is pivotally supported by a pivotal support shaft 6 ', and is connected to a reinforcing support plate 8a attached to a side surface of the hopper body 2. 21 of a tension spring 22 having one end engaged with it. Connected at the top end and a side plate 5b, it is formed so as to close the bottom along the other edge 2a "in the side plate 2a of the constantly hopper body 2 by the tension spring 22.

このような主動ゲート板４と従動ゲート板５とは、その両ゲート板４，５の先端部４ｃ，５ｃがホッパ本体２の下向き開口部を閉じて重なり合わない状態で閉鎖するようにされている。そして、主動ゲート板４の先端部４ｃには、断面鉤形状に屈曲形成された受け板４ｄがホッパの開口部全幅にわたり、図１（ｂ）のＰ詳細に示されるように、主動ゲート板４の底板４ａ内面から下側へ段差を付けて一体に取着形成されている。こうして、従動ゲート板５と主動ゲート板４との先端部４ｃ、５ｃには噛み込み物品の受止め部２０が設けられる。   The main gate plate 4 and the driven gate plate 5 are closed in such a manner that the tip portions 4c, 5c of the gate plates 4, 5 close the downward opening of the hopper body 2 and do not overlap. Yes. Then, a receiving plate 4d bent and formed in a cross-sectional shape is formed at the front end portion 4c of the main gate plate 4 over the entire width of the opening of the hopper, as shown in detail in P of FIG. The bottom plate 4a is integrally attached with a step from the inner surface to the lower side. Thus, the biting article receiving portion 20 is provided at the tip portions 4c and 5c of the driven gate plate 5 and the main gate plate 4.

このように構成された本実施形態のホッパは、組合せ秤の供給ホッパ１として使用に供すれば、ゲート部３を閉じた供給ホッパ１に対し、分散フィーダ３０（以下、図４参照）からリニアフィーダ３１に分配して搬送される被計量物（物品）４０が送り込まれ、所定のブログラムによってゲート（主動ゲート板４）を開くと、受け入れていた被計量物４０が、この供給ホッパ１の下側に位置する計量ホッパ３５に投入される。   The hopper according to the present embodiment configured as described above is linearly supplied from the dispersion feeder 30 (refer to FIG. 4 below) to the supply hopper 1 with the gate portion 3 closed when used as the supply hopper 1 of the combination weigher. When an object to be weighed (article) 40 distributed and fed to the feeder 31 is sent and a gate (main gate plate 4) is opened by a predetermined program, the object to be weighed 40 is received from the supply hopper 1. It is put into the weighing hopper 35 located on the lower side.

前記供給ホッパ１のゲート（主動ゲート板４）は、制御装置３８からの指令信号でアクチュエータ１８にゲート開操作の信号が与えられると、搖動リンク１６を図２上で位置Ａから位置Ｂまで回動させることにより、その搖動リンク１６の切込み溝１６ａに係合する操作軸ピン１５が移動させられる。すると、この操作軸ピン１５が取付く回動リンク１４が枢支軸１２上で図上上向きに回動変位され、この回動リンク１４の先端に軸１７で連結されるリンク１１が引上げられる。リンク１１が連結する回動リンク１４でもって引上げ変位されると、このリンク１１の他端が軸ピン７ａにて連結される主動ゲート板４に付設のブラケット７が引かれる。すると、この主動ゲート板４は基端部をホッパ本体２の側板２ａに枢支軸６にて枢支されているので、連結するリンク１１の変位に追従して、枢支軸６を基点として外向きに回動され、図３（ａ）で示されるように、供給ホッパ１の開口部が開かれる。そして、この主動ゲート板４は回動リンク１４が最大変位すると、図上符号Ｃで示されるように、先端部４ｃが真下位置まで移動され、供給ホッパ１内にある被計量物４０（物品）が下部位置の計量ホッパ３５内に全量流下する。   The gate (mainly driven gate plate 4) of the supply hopper 1 rotates the peristaltic link 16 from position A to position B in FIG. 2 when a gate opening operation signal is given to the actuator 18 by a command signal from the control device 38. By moving, the operation shaft pin 15 engaged with the cut groove 16a of the peristaltic link 16 is moved. Then, the turning link 14 to which the operation shaft pin 15 is attached is turned and displaced upward on the pivot shaft 12, and the link 11 connected to the tip of the turning link 14 by the shaft 17 is pulled up. When the link 11 is pulled up and displaced by the rotating link 14 connected, the bracket 7 attached to the main driving gate plate 4 to which the other end of the link 11 is connected by the shaft pin 7a is pulled. Then, since the main gate plate 4 is pivotally supported on the side plate 2a of the hopper body 2 by the pivot shaft 6, the main gate plate 4 follows the displacement of the link 11 to be connected, and uses the pivot shaft 6 as a base point. As shown in FIG. 3A, the opening of the supply hopper 1 is opened. When the pivot link 14 is displaced to the maximum extent, the main gate plate 4 is moved to the position just below the tip 4c as indicated by the symbol C in the figure, and the object to be weighed 40 (article) in the supply hopper 1 is shown. Flows down into the weighing hopper 35 at the lower position.

この主動ゲート板４の開動作に対して、従動ゲート板５は、連結されず側面板５ｂの上部でホッパ本体２との間で引張ばね２２にて引寄せられて閉じ方向に保持されているので、ホッパの底部片方を閉じた状態に保っている。しかし、その従動ゲート板５は内面をホッパ本体２の底部縁の傾斜に沿って閉じているから、開口時にホッパの底部片側で傾斜面を保って収容物品（被計量物４０）の流れを促進させる案内面の働きをする。   In response to the opening operation of the main driving gate plate 4, the driven gate plate 5 is not connected and is attracted by the tension spring 22 between the upper portion of the side plate 5b and the hopper body 2 and held in the closing direction. Therefore, the bottom of the hopper is kept closed. However, since the driven gate plate 5 is closed on the inner surface along the inclination of the bottom edge of the hopper body 2, the inclined gate surface is maintained on one side of the bottom of the hopper when opening to facilitate the flow of the stored article (object 40). It works as a guide surface.

主動ゲート板４は、供給ホッパ１から被計量物４０が排出された後、閉じる指令でアクチュエータ１８が閉動作すると、搖動リンク１６の逆回動によって回動リンク１４を始めリンク１１が前記開放時と逆に作動して、主動ゲート板４が開放位置から元の閉鎖位置へと変位する。そして、正常時にはそのまま主動ゲート板４がホッパ本体２の側板縁部２ａ′に当接して開口部を閉じるので、次の被計量物４０の放出時まで閉鎖状態を維持する。   After the workpiece 40 is discharged from the supply hopper 1, the main gate plate 4 is closed when the actuator 18 is closed by a closing command. The main gate plate 4 is displaced from the open position to the original closed position. In the normal state, the main gate plate 4 directly contacts the side plate edge 2a 'of the hopper body 2 and closes the opening, so that the closed state is maintained until the next measurement object 40 is discharged.

ところが、例えば前記主動ゲート板４が閉鎖する直前に、作動停止状態のリニアフィーダ３６のフィーダパン３６ａから被計量物（物品４０）が突然供給ホッパ１内に落下するような事態が発生すると、閉じ合う直前のゲート部３では主動ゲート板４と従動ゲート板５との先端部４ｃ，５ｃ間に隙間が生じているので、この隙間に落下した被計量物（物品４０）が噛み込むことになる。もしこの物品４０が硬くて長物（例えばペットフードのようなもの）である場合、その物品４０の噛み込みによって閉じ方向に作動しているゲート開閉機構１０には、当然過負荷が作用する。しかしながら、前述のように主動ゲート板４に対向配置されている従動ゲート板５は、引張ばね２２によって閉鎖状態に保持されているから、主動ゲート板４がさらに閉じ方向に移動すると、従動ゲート板５は噛み込んだ物品４０に作用する押圧力で引張ばね２２を伸ばし、その先端部５ｃが図３（ｂ）に示されるように押されて、枢支軸６′を支点として開方向へ回動変位される。   However, for example, immediately before the main gate plate 4 is closed, if a situation occurs in which an object to be weighed (article 40) suddenly falls into the supply hopper 1 from the feeder pan 36a of the linear feeder 36 in the operation stop state, the gate hopper 1 is closed. In the gate portion 3 immediately before the mating, a gap is formed between the front end portions 4c, 5c of the main gate plate 4 and the driven gate plate 5, so that the object to be weighed (article 40) that has fallen into this gap is caught. . If the article 40 is hard and long (such as a pet food), an overload naturally acts on the gate opening / closing mechanism 10 operating in the closing direction by the biting of the article 40. However, since the driven gate plate 5 disposed opposite to the main gate plate 4 is held in the closed state by the tension spring 22 as described above, when the main gate plate 4 further moves in the closing direction, the driven gate plate. 5, the tension spring 22 is extended by the pressing force acting on the bitten article 40, and its tip 5c is pushed as shown in FIG. 3 (b) to rotate in the opening direction with the pivot shaft 6 'as a fulcrum. It is displaced dynamically.

こうして従動ゲート板５は、主動ゲート板４と別に回動操作されるので、主動ゲート板４がゲート開閉機構１０の作動でそのまま閉止位置まで移動して停止し、その状態で保持される。したがって、ゲート開閉機構１０ならびにアクチュエータ１８には過負荷が作用しない。一方、従動ゲート板５の先端部５ｃと主動ゲート板４の先端部４ｃとによって挟まれた物品４０は、従動ゲート板５の先端部５ｃに付随して移動することになり、一旦後退回動した従動ゲート板５が主動ゲート板４の閉鎖位置への到達で物品４０に作用する負荷が除かれた状態になると引張ばね２２の復元力により元の位置に戻される際に、先端部５ｃに接している物品４０が弾き上げられてゲート部３の上（供給ホッパ１内）に残留することになる。なお、主動ゲート板４の先端部４ｃには段付状態で受け板４ｄが付されているので、物品４０は従動ゲート板５が後退して後復帰するまでの間その受け板４ｄと従動ゲート板５の先端部５ｃとによって落下することなく保持される。   Thus, the driven gate plate 5 is rotated separately from the main gate plate 4, so that the main gate plate 4 is moved to the closing position as it is by the operation of the gate opening / closing mechanism 10 and is stopped and held in that state. Therefore, an overload does not act on the gate opening / closing mechanism 10 and the actuator 18. On the other hand, the article 40 sandwiched between the distal end portion 5c of the driven gate plate 5 and the distal end portion 4c of the driven gate plate 4 moves along with the distal end portion 5c of the driven gate plate 5, and temporarily rotates backward. When the driven gate plate 5 reaches the closed position of the main gate plate 4 and the load acting on the article 40 is removed, when the driven gate plate 5 is returned to the original position by the restoring force of the tension spring 22, The contacting article 40 is flipped up and remains on the gate portion 3 (in the supply hopper 1). In addition, since the receiving plate 4d is attached to the front end portion 4c of the main driving gate plate 4 in a stepped state, the article 40 and the receiving gate 4d and the driven gate are used until the driven gate plate 5 moves backward and then returns. It is held without dropping by the tip 5c of the plate 5.

したがって、下部に位置する計量ホッパ３５内で計量済みの物品に後から物品４０が付加されることもなく、計量に狂いが生じるのを防止できる。なお、この供給ホッパ１に後から落下した物品４０は、次の被計量物（物品）の計量ホッパ３５への排出時同時に投入されることになって支障は来たさない。また、前記落下した物品４０は、主動ゲート板４と従動ゲート板５との先端に噛み込まないので、損壊することもない。   Therefore, the article 40 is not added to the article already weighed in the weighing hopper 35 located at the lower portion, and it is possible to prevent the weighing from being distorted. It should be noted that the article 40 that has subsequently dropped onto the supply hopper 1 is thrown in at the same time as the next object to be weighed (article) is discharged into the weighing hopper 35, so that there is no problem. Moreover, since the dropped article 40 is not bitten by the leading ends of the main gate plate 4 and the driven gate plate 5, the article 40 is not damaged.

このように、本実施形態のゲートを備えるホッパによれば、簡単な構成でもってゲート部に物品が噛み込む事態が発生しても、そのゲートの開閉操作を行わせる機構に過剰な負荷を与えることなく操作できるので、耐久性を維持し、かつ破損しやすい部材を用いないので、異物混入の恐れなく、また、清浄化作業に際しても障害物がないから清掃を容易にして衛生管理を向上させ得るという効果を奏する。   As described above, according to the hopper including the gate of the present embodiment, an excessive load is applied to the mechanism that opens and closes the gate even when an article is caught in the gate portion with a simple configuration. Since there is no risk of contamination, there is no obstacle during cleaning work, and it is easy to clean and improve hygiene management. There is an effect of obtaining.

上記実施形態の説明においては、供給ホッパについて記載したが、これに限定されるものではなく、計量ホッパに適用することも任意なし得る。また、必要に応じて前記主動ゲート板の先端に付設される受け板を省略することもできる。   In the description of the above embodiment, the supply hopper has been described. However, the present invention is not limited to this and can be arbitrarily applied to the weighing hopper. Moreover, the receiving plate attached to the front-end | tip of the said main gate plate can also be abbreviate | omitted as needed.
