In FIG. 3, the one triangular pocket shutter 26 is pressed and closed in the direction of the central partition plate 28, and in order to maintain this state, the opening / closing plate 22 has a leftward side view. Energizing pressure is applied.
他方の三角ポケットシャッター２７は、回転軸２５を中心に回転可能に軸支されており、この回転軸２５には開閉板２３が取り付けられている。 The other triangular pocket shutter 27 is pivotally supported around a rotation shaft 25, and an opening / closing plate 23 is attached to the rotation shaft 25.
原料供給機構３は、自動包装機本体からの指示を受けて充填筒２１を側面視左方向に回転させる。この結果、ホッパー２内の粉末原料は落下筒２０と充填筒２１を経由して一方の三角ポケットシャッター２６内に落下し、この粉末原料が充填筒２１の最下端の位置まで充満した状態で落下停止になり、一方の三角ポケットシャッター２６内に保持されている。 In response to an instruction from the automatic packaging machine body, the raw material supply mechanism 3 rotates the filling cylinder 21 leftward in a side view. As a result, the powder raw material in the hopper 2 falls into one triangular pocket shutter 26 through the dropping cylinder 20 and the filling cylinder 21, and the powder raw material falls in a state where the powder raw material is filled to the lowest end position of the filling cylinder 21. It is stopped and held in one triangular pocket shutter 26.
また、上記粉末原料が一方の三角ポケットシャッター２６内に投入される動作と同時に、開閉板２３は側面視左方向の駆動力を受けて回転軸２５を中心に他方の三角ポケットシャッター２７を開放する。この結果、他方の三角ポケットシャッター２７内に保持されていた計量済み粉末原料は、直下の包装袋内に充填されて原料供給作業が完了し、三角ポケットシャッター２７内の粉末原料が全て落下した後、開閉板２３に対して側面視右方向の駆動力が加わり、他方の三角ポケットシャッター２７は閉鎖される。 Simultaneously with the operation in which the powder raw material is charged into one triangular pocket shutter 26, the opening / closing plate 23 receives the driving force in the left direction when viewed from the side, and opens the other triangular pocket shutter 27 around the rotation shaft 25. . As a result, the weighed powder raw material held in the other triangular pocket shutter 27 is filled in the packaging bag immediately below, and the raw material supply operation is completed. After the powder raw material in the triangular pocket shutter 27 has all dropped. A driving force in the right direction in side view is applied to the opening / closing plate 23, and the other triangular pocket shutter 27 is closed.
なお、この開閉板２２と開閉板２３を開閉する装置としては、エアーシリンダ等のエアー圧力駆動装置、その他機械的なバネ部材等の弾性圧力駆動装置などが考えられる。 As an apparatus for opening and closing the opening / closing plate 22 and the opening / closing plate 23, an air pressure driving device such as an air cylinder, and an elastic pressure driving device such as a mechanical spring member may be considered.
そして、一方の三角ポケットシャッター２６等を軸支している回転軸２４と他方の三角ポケットシャッター２７等を軸支している回転軸２５は、シャッター固定板２９に取り付けられており、このシャッター固定板２９は、量目調整機構の位置調整板３０と連結されている。 A rotating shaft 24 that supports one triangular pocket shutter 26 and the like and a rotating shaft 25 that supports the other triangular pocket shutter 27 and the like are attached to a shutter fixing plate 29. The plate 29 is connected to the position adjusting plate 30 of the quantity adjusting mechanism.
上記量目調整機構は、位置調整板３０と、支持棒３１及び支持棒３２と、ネジ棒３３と、量目調整ツマミ３４とで構成されており、位置調整板３０は支持棒３１及び支持棒３２によって上下位置自在で支えられると共に、ネジ棒３３が螺動回転自在に嵌め込まれている。そして、ネジ棒３３の最上部には量目調整ツマミ３４が取り付けられており、この量目調整ツマミ３４を上面視右回転させると位置調整板３０が上昇し、連結されたシャッター固定板２９と一方の三角ポケットシャッター２６及び他方の三角ポケットシャッター２７等も一緒に上昇する。 The amount adjustment mechanism includes a position adjustment plate 30, a support rod 31, a support rod 32, a screw rod 33, and an amount adjustment knob 34. The position adjustment plate 30 includes the support rod 31 and the support rod. The screw rod 33 is fitted in a freely rotatable manner while being supported by the upper and lower positions 32 and 32. A quantity adjustment knob 34 is attached to the uppermost part of the screw rod 33. When the quantity adjustment knob 34 is rotated to the right when viewed from above, the position adjustment plate 30 rises, and the connected shutter fixing plate 29 and One triangular pocket shutter 26, the other triangular pocket shutter 27, and the like are also raised together.
また、量目調整ツマミ３４を上面視左回転させると位置調整板３０が下降し、連結されたシャッター固定板２９と一方の三角ポケットシャッター２６及び他方の三角ポケットシャッター２７等も一緒に下降する。 When the amount adjustment knob 34 is rotated counterclockwise as viewed from above, the position adjustment plate 30 is lowered, and the connected shutter fixing plate 29, one triangular pocket shutter 26, the other triangular pocket shutter 27, and the like are also lowered together.
図４は、本発明の原料供給機構３において、充填筒２１を側面視右方向に回転させて他方の三角ポケットシャッター２７内にホッパー２内の粉末原料を投入して原料計量動作を行っている状態を表した側面図である。なお、この図４においては、構成及び動作を説明し易くするために一部部材を省略して記載している。図４に示すように、原料供給機構３は、自動包装機本体からの指示を受けて充填筒２１を側面視右方向に回転させる。この結果、充填筒２１は図３に示した一方の三角ポケットシャッター２６内に対する原料充填動作に引き続いて中央仕切り板２８による摺切り動作を経て図示された位置まで回転駆動され、ホッパー２内の粉末原料を落下筒２０と充填筒２１を経由させて他方の三角ポケットシャッター２７内に落下させる。その後、この粉末原料が充填筒２１の最下端の位置まで充満した状態で落下停止になる。 FIG. 4 shows the raw material supply mechanism 3 according to the present invention, in which the filling cylinder 21 is rotated to the right in a side view, and the powder raw material in the hopper 2 is charged into the other triangular pocket shutter 27 to perform the raw material measurement operation. It is a side view showing a state. In FIG. 4, some members are omitted for easy explanation of the configuration and operation. As shown in FIG. 4, the raw material supply mechanism 3 receives the instruction from the automatic packaging machine body and rotates the filling cylinder 21 in the right direction when viewed from the side. As a result, the filling cylinder 21 is rotationally driven to the illustrated position through the sliding operation by the central partition plate 28 following the raw material filling operation for one triangular pocket shutter 26 shown in FIG. The raw material is dropped into the other triangular pocket shutter 27 via the dropping cylinder 20 and the filling cylinder 21. Thereafter, the powder raw material is stopped to fall in a state where the powder raw material is filled to the lowermost position of the filling cylinder 21.
そして、この間の開閉板２３には側面視左方向の付勢圧力がかかっているため落下した粉末原料は他方の三角ポケットシャッター２７内に保持されている。 The open / close plate 23 during this time is applied with a biasing pressure in the left direction as viewed from the side, so that the powder material that has fallen is held in the other triangular pocket shutter 27.
即ち、一方の三角ポケットシャッター２６内に投入された粉末原料の計量動作は、充填筒２１の最下端と中央仕切り板２８の最上端による摺切り動作を経ることにより、所定の計量値になって終了することになる。 That is, the weighing operation of the powder raw material put into one triangular pocket shutter 26 becomes a predetermined measurement value through the sliding operation by the lowermost end of the filling cylinder 21 and the uppermost end of the central partition plate 28. Will end.
この中央仕切り板２８の最上端は、図示の如く、四角形状以外の形状、即ち、円弧形状（Ｒ形状）になっているため、この円弧状部分が摺切り動作に合わせて充填筒２１の最下端から少し飛び出した固形原料を徐々に充填筒２１内に押し戻すように動き、固形原料の挟み込み状態を大幅に減少させることになる。この結果、フリーズドライタイプ野菜等の固形物質が入った原料でもこれら固形物質を破砕することなく、所定の原料形状のまま計量並びに供給できると共に、粉砕された破断原料が飛び散って計量値が減少する問題も抑止され、同時に、飛び散った破断原料によって多列スティック自動包装機周辺が汚染される事態も解消できる。 Uppermost end of the central partition plate 28, as shown, the shape other than the rectangular shape, i.e., since an arc shape (R shape), the filling tube 21 the arcuate portion is in accordance with the sliding cutting operation The solid raw material that slightly protrudes from the lowest end moves so as to be gradually pushed back into the filling cylinder 21, thereby greatly reducing the sandwiching state of the solid raw material. As a result, raw materials containing solid substances such as freeze-dried vegetables can be measured and supplied in the prescribed raw material shape without crushing these solid substances, and the crushed broken raw material scatters and the measured value decreases. The problem is also suppressed, and at the same time, the situation where the surroundings of the multi-row stick automatic packaging machine are polluted by the broken broken raw material can be solved.
また、上記粉末原料が一方の三角ポケットシャッター２７内に投入される動作と同時に、開閉板２２は側面視右方向の駆動力を受けて回転軸２４を中心に一方の三角ポケットシャッター２６を開放する。この結果、一方の三角ポケットシャッター２６内に保持されていた計量済み粉末原料は、直下の包装袋内に充填されて原料供給作業が完了し、三角ポケットシャッター２６内の粉末原料が全て落下した後、開閉板２２に対して側面視左方向の駆動力が加わり、一方の三角ポケットシャッター２６は閉鎖される。 Simultaneously with the operation in which the powder raw material is introduced into one triangular pocket shutter 27, the opening / closing plate 22 receives a driving force in the right direction when viewed from the side, and opens one triangular pocket shutter 26 around the rotation shaft 24. . As a result, the weighed powder raw material held in one triangular pocket shutter 26 is filled in the packaging bag immediately below, and the raw material supply operation is completed, and all the powder raw material in the triangular pocket shutter 26 is dropped. The left and right driving force is applied to the opening / closing plate 22 in a side view, and the one triangular pocket shutter 26 is closed.
そして、図３と図４に示した原料供給機構３の動作を交互に繰り返すことによって、連続的な原料計量供給動作が行われることになる。 And the operation | movement of the raw material supply mechanism 3 shown in FIG. 3 and FIG. 4 is repeated alternately, and continuous raw material measurement supply operation | movement is performed.
これまでの説明は、本発明の原料供給機構３における通常の計量動作場面であるが、本発明の原料供給機構３が計量動作を停止している状態は、図３若しくは図４と同様に、充填筒２１を一方の三角ポケットシャッター２６若しくは他方の三角ポケットシャッター２７どちらかの方向に回転させて、その状態を保持させて実現している。即ち、ホッパー２内の粉末原料は、落下筒２０と充填筒２１を経由して三角ポケットシャッター２６若しくは三角ポケットシャッター２７どちらかの内部に落下して充填筒２１の最下端の位置まで充満した状態で落下停止になるため、原料の供給を停止できる。当然、粉末原料が充満した状態で停止している三角ポケットシャッターに対して、反対側の三角ポケットシャッターは、内部が空の状態で閉鎖状態になっている。 The description so far is a normal measuring operation scene in the raw material supply mechanism 3 of the present invention, but the state in which the raw material supply mechanism 3 of the present invention stops the measuring operation is similar to FIG. 3 or FIG. This is realized by rotating the filling cylinder 21 in the direction of one of the triangular pocket shutter 26 or the other triangular pocket shutter 27 and holding the state. That is, the powder raw material in the hopper 2 falls into either the triangular pocket shutter 26 or the triangular pocket shutter 27 via the dropping cylinder 20 and the filling cylinder 21 and is filled to the lowermost position of the filling cylinder 21. The supply of raw materials can be stopped because it stops falling. As a matter of course, the triangular pocket shutter on the opposite side is closed with the inside being empty with respect to the triangular pocket shutter that is stopped in a state where the powder raw material is filled.
図５は、本発明の原料供給機構３における充填筒２１と円弧形状の中央仕切り板２８と、二つの三角ポケットシャッター２６、２７の動きを説明するための概略図であり、図６は、本発明の原料供給機構３における充填筒２１と台形形状の中央仕切り板３８と、二つの三角ポケットシャッター２６、２７の動きを説明するための概略図である。図５及び図６に示すように、これらの部材に関する全体的な動きは以下の通りである。 FIG. 5 is a schematic diagram for explaining the movement of the filling cylinder 21, the arc-shaped central partition plate 28, and the two triangular pocket shutters 26 and 27 in the raw material supply mechanism 3 of the present invention. It is the schematic for demonstrating the motion of the filling cylinder 21, the trapezoid-shaped center partition plate 38, and the two triangular pocket shutters 26 and 27 in the raw material supply mechanism 3 of invention. As shown in FIGS. 5 and 6, the overall movement for these members is as follows.
（１）充填筒２１は、一方の三角ポケットシャッター２６内に位置しており、ホッパー２内の粉末原料が一方の三角ポケットシャッター２６内における充填筒２１の最下端の位置まで充満した状態３７で落下停止している。 (1) The filling cylinder 21 is located in one triangular pocket shutter 26, and the powder raw material in the hopper 2 is filled up to the lowermost position of the filling cylinder 21 in the one triangular pocket shutter 26. The fall has stopped.
（２）次に、他方の三角ポケットシャッター２７が閉鎖されると共に、充填筒２１を右方向に回転させて充填筒２１の最下端と中央仕切り板２８若しくは３８の最上端による摺切り動作を行う。この際、図５においては、中央仕切り板２８の最上端は、円弧形状（Ｒ形状）から成る否四角形状になっており、図６においては、中央仕切り板３８の最上端は、同じく台形形状から成る否四角形状に成っている。 (2) Next, the other triangular pocket shutter 27 is closed and the filling cylinder 21 is rotated to the right to perform a sliding operation by the lowermost end of the filling cylinder 21 and the uppermost end of the central partition plate 28 or 38. . At this time, in FIG. 5, the uppermost of the central partition plate 28 is adapted to not square shape consisting of a circular arc shape (R shape), in FIG. 6, the uppermost end of the central partition plate 38, like trapezoid The shape is a non- rectangular shape .
（３）この結果、この円弧状部分若しくは台形形状部分から成る否四角形状部分が、摺切り動作に合わせて充填筒２１の最下端から少し飛び出した固形原料を徐々に充填筒２１内に押し戻すように動き固形原料の挟み込み状態を大幅に減少させることになる。 (3) As a result, the non- rectangular portion composed of the arc-shaped portion or the trapezoidal shape portion gradually pushes back the solid raw material slightly protruding from the lowermost end of the filling cylinder 21 into the filling cylinder 21 in accordance with the sliding operation. This greatly reduces the state of sandwiching the solid raw material.
（４）即ち、このような摺切り動作により、フリーズドライタイプ野菜等の固形物質が入った原料でもこれら固形物質を破砕することなく、所定の原料形状のまま計量並びに供給できると共に、粉砕された破断原料が飛び散って計量値が減少する問題も抑止され、同時に、飛び散った破断原料によって多列スティック自動包装機周辺が汚染される事態も解消できる。 (4) That is, by such a scraping operation, even raw materials containing solid substances such as freeze-dried vegetables can be metered and supplied in a predetermined raw material shape without being crushed and crushed. The problem that the measured value decreases due to the broken raw material being scattered is also suppressed, and at the same time, the situation where the periphery of the multi-row stick automatic packaging machine is contaminated by the broken raw material can be solved.
なお、本発明の実施の形態は本発明を具現化するための一例を示したものであり、特許請求の範囲における発明特定事項とそれぞれ対応関係を有するが、これに限定されるものではなく本発明の要旨を逸脱しない範囲において種々の変形を施すことができる。 The embodiment of the present invention is an example for embodying the present invention, and has a corresponding relationship with the invention-specific matters in the claims, but is not limited thereto. Various modifications can be made without departing from the scope of the invention.
例えば、本実施の形態では、２列のスティックタイプ自動包装機の例で説明したがこれに限るものではなく、他の複数列のスティックタイプ自動包装機にも採用することができる。 For example, in the present embodiment, an example of a two-row stick-type automatic packaging machine has been described. However, the present invention is not limited to this, and the present invention can also be applied to other multiple-row stick-type automatic packaging machines.
また、図５、図６における中央仕切り板の最上端形状は、否四角形状の実施例として、円弧状若しくは台形形状の例を用いて説明したが、これに限定するものではなく、摺切り動作における挟み込み現象を軽減できる仕組みであれば自由に採用することができる。 Moreover, although the uppermost end shape of the center partition plate in FIGS. 5 and 6 has been described using an example of an arc shape or a trapezoidal shape as an example of a non-rectangular shape, it is not limited to this, and a sliding operation is performed. Any mechanism that can reduce the pinching phenomenon in can be used freely.
例えば、中央仕切り板の最上端形状を図示はしていないが三角形状としても良く、この場合の三角形状の頂角は、鋭角ではなくて９０度以上の鈍角を採用した方が飛び出した固形原料を充填筒２１内に押し戻す作用が発揮できる。また、中央仕切り板の最上端にブラシ部材を付与して摺切り動作を行うように構成しても同じような作用効果を期待できる。 For example, although the uppermost end shape of the central partition plate is not illustrated, it may be a triangular shape. In this case, the apex angle of the triangular shape is not a sharp angle, but a solid material that protrudes by adopting an obtuse angle of 90 degrees or more Can be pushed back into the filling cylinder 21. Further, the same effect can be expected even when a brush member is applied to the uppermost end of the central partition plate to perform the sliding operation.
なお、このような中央仕切り板の最上端形状は、粉末原料の性質や混在している固形物質の大きさ等によって適宜選択されて決定される。 In addition, the uppermost end shape of such a central partition plate is appropriately selected and determined depending on the properties of the powder raw material, the size of mixed solid substances, and the like.
