Description
本発明は、細く捻った袋口の周囲にプラスティツク製の結束材を、力強く噛み付かせるために用いる結束装置に関する。 The present invention relates to a bundling device used to force a plastic bundling material to bite around a narrowly twisted bag mouth.
豚肉ミンチを充填したプラスティツクチューブ開口端を、馬蹄形のアルミニューム製のクリップで結束したソーセージは、広く一般に知られる。前記クリップを構成するアルミニュウムは他の金属に比較して塑性に優れ、袋口を絞めこむ力を充分発揮するが、食品に混合した金属を検査する際、当該検査機器に反応する難点がある。 A sausage in which a plastic tube open end filled with pork mince is bound with a clip made of horseshoe-shaped aluminum is widely known. The aluminum constituting the clip is superior in plasticity compared to other metals and exhibits a sufficient force to squeeze the bag mouth. However, when inspecting the metal mixed in food, there is a difficulty in reacting to the inspection equipment.
下記特許文献1は、連鎖化したプラスティツク製馬蹄形クリップをリールから解きながら袋口を結束する装置の構造を開示し、金属検査機での反応から逃れる。しかし塑性のあるポリカーボネイトを材質とするこの種クリップも、アルミニュームに比較すると弾力があるので、袋口の締め付けが緩むという難点がある。 Patent Document 1 below discloses a structure of an apparatus for binding a bag mouth while unwinding a chained plastic horseshoe clip from a reel, and escapes from a reaction in a metal inspection machine. However, this kind of clip made of plastic polycarbonate is also more resilient than aluminum, so there is a difficulty in loosening the bag mouth.
下記特許文献2に開示する結束材は、馬蹄状プラスティツク結束材の両端に互いに係合し合う鉤端を形成し、袋口に巻きつけた前記結束材を、前記両鉤端の係合で環状に一体化し、同結束材内面のひげ状突起材の弾力で前記袋口を締め付ける構造である。しかし前記ひげ状突起材は弾力で内側に張り出す反面、当該弾力に抗する反力で後退する構成になっているから、気密性には難点がある。 The binding material disclosed in the following Patent Document 2 is formed with hook ends engaging with each other at both ends of a horseshoe-shaped plastic binding material, and the binding material wound around the bag mouth is formed into an annular shape by engaging the both ends. And the bag mouth is tightened by the elasticity of the whisker-like projection material on the inner surface of the binding material. However, the whisker-like projection material protrudes inward with elasticity, but has a problem in airtightness because it is configured to recede with reaction force against the elasticity.
本発明は緩みのない結束材を袋口に装着する装置として、重ね合わせた2種のカバー材間のトンネル軌道に沿って縦列状の多数の結束材を、両サイドの帯と一体に1ピッチづつ断続運搬する手段と、前記トンネル軌道における一次セクション両側それぞれに設置した一対の切断刃及び、前記結束材の雄要素折り曲げ機構と、前記トンネル軌道における二次セクションおいて、前記トンネル軌道から上域の袋口案内スリットに向けて、前記の雄要素を折り曲げ状態に維持して結束材を案内するリフトガイドと、
前記リフトガイドにおいて前記結束材を押し上げる昇降台座と、前記リフトガイドに交差する軌道に設置した前記雄要素の閉鎖バーとからなり、前記一次セクションに設置した一対の切断刃により前記結束材両端の繋ぎ材を両サイドの帯からカットする一方、前記折り曲げ機構でもって前記結束材の雄要素を直角に立ち上げ、前記雄要素を折り曲げた結束材を、前記二次セクションのリフトガイドを通して、前記台座でもって上域の前記袋口案内スリットに向けて押し上げ、さらに前記閉鎖バーの押し出しにより前記雄要素を押し倒し、前記雄要素先端の鉤を、前記結束材雌要素の鉤に係合して構成する。
The present invention is a device for attaching a loose binding material to a bag mouth, and a large number of vertical binding materials along a tunnel track between two overlapping cover materials are integrated into one pitch with a band on both sides. Means for intermittently transporting one by one, a pair of cutting blades installed on both sides of the primary section of the tunnel track, a male element bending mechanism of the binding material, and a secondary section of the tunnel track, wherein A lift guide that guides the binding material while maintaining the male element in a bent state toward the bag mouth guide slit of
The lift guide comprises a lifting pedestal that pushes up the binding material and a closing bar of the male element installed on a track intersecting the lift guide, and the ends of the binding material are joined by a pair of cutting blades installed in the primary section. While cutting the material from the strips on both sides, the bending element is used to raise the male element of the binding material at a right angle, and the binding material obtained by bending the male element is passed through the lift guide of the secondary section on the pedestal. Therefore, the male element is pushed up by pushing up toward the bag opening guide slit in the upper region, and the male element is pushed down by pushing out the closing bar, so that the hook at the tip of the male element is engaged with the hook of the female element of the binding material.
特許請求の範囲に記載する結束材とは、図11に示すごとく舟形の雌要素10 と、前記雌要素の溝内に押し込むヘラ11を備える雄要素12とを、連結材13を介しかつ軟質プラスティツクにより一体成型したもので、図12のごとく前記連結材16の柔軟性を利用して雄要素12を折り曲げ、前記図11における雄要素の鉤17を、雌要素の鉤18に係合し、ヘラ11でもって袋口を雌要素10内に押し込み挟圧するもの、と特定する。 As shown in FIG. 11, the binding material described in the claims includes a boat-shaped female element 10 and a male element 12 provided with a spatula 11 that is pushed into the groove of the female element via a connecting material 13 and a soft plastic. The male element 12 is bent using the flexibility of the connecting member 16 as shown in FIG. 12, and the male element collar 17 in FIG. 11 to specify that the bag mouth is pushed into the female element 10 and pinched.
多数の結束材を両サイドの帯と一体化した連鎖結束材を1ピッチづつ断続運搬する。最先端の結束材が一次セクションで停止すると、一対の切断刃は突き出し前記結束材両端の繋ぎ材を、両サイドの帯びからカットし、同時に折り曲げ要素により前記結束材における雄要素を約90に折り曲げる。 A chain binding material in which a large number of binding materials are integrated with bands on both sides is intermittently transported by one pitch. When the state-of-the-art binding material stops at the primary section, a pair of cutting blades protrude and cut the connecting material at both ends of the binding material from the bands on both sides, and simultaneously bend the male element in the binding material to about 90 by the folding element. .
前記の結束材が二次セクションに1ピッチ進むと、昇降台座はリフトガイドに沿って前記の結束材を、雄要素が90度角を維持した状態で押し上げ、上域のスリットに押し込んだ袋口に前記の結束材を被せる。その直後、横方向から閉鎖バーが突き出て前記の雄要素を倒して袋口の上に被せると共に、雄要素の鉤と、雌要素の鉤とを強制的に係合するのである。なお昇降台座の運動方向が特許請求の範囲に記載した上方向には限定せず、横又は下方向に変更することも在り得るもので、それに伴い、閉鎖バーの運動方向が変化することには何らの不自然さはないものと考えられるのである。 When the binding material advances one pitch to the secondary section, the lifting platform squeezes the binding material along the lift guide while the male element maintains a 90-degree angle, and pushes it into the upper slit. Cover the above-mentioned binding material. Immediately after that, a closing bar protrudes from the lateral direction, and the male element is brought down and put on the bag mouth, and the male element's heel and the female element's heel are forcibly engaged. The movement direction of the lifting pedestal is not limited to the upward direction described in the claims, but may be changed to the horizontal or downward direction, and the movement direction of the closing bar changes accordingly. It is considered that there is no unnaturalness.
図5は、装置一部の側面図であり、リール19にロール巻きした連鎖結束材10を、上下に重ね合わせた2種のカバー21,22間に形成したトンネル軌道23に誘導する構成を示し、前後2基の流体シリンダー24,25のピストンロッドに支持する送り爪26,27が、前記連鎖結束材10を1ピッチづつ断続運搬するものである。 FIG. 5 is a side view of a part of the apparatus, and shows a configuration in which the chain binding material 10 rolled around the reel 19 is guided to the tunnel track 23 formed between the two types of covers 21 and 22 stacked one above the other. The feeding claws 26 and 27 supported by the piston rods of the two front and rear fluid cylinders 24 and 25 intermittently convey the chain binding material 10 by one pitch.
前記両送り爪の正面図である図9のごとく、シリンダー24のピストンロッド55に固定したブラケット56は、前記送り爪26を回転自在に支持する軸57を備え、ねじりコイルスプリング58は、前記送り爪26に逆止め効果を発揮させる。 As shown in FIG. 9 which is a front view of the both feed claws, the bracket 56 fixed to the piston rod 55 of the cylinder 24 includes a shaft 57 that rotatably supports the feed claws 26, and the torsion coil spring 58 includes the feed claws 58. The nail | claw 26 is made to exhibit a non-return effect.
先に説明した図5に連続する図7において、2個の前記送り爪26,27は、連鎖結束材10の送り方向に同時前進し、後退は交互に動作して連鎖結束材10に対する逆止めの緩みを防止する。カバー21に設置したセンサー59が、移送中の連鎖結束材10の末端を検出すると、アラーム60は発信するが、この場合最前位の逆止爪61は、後位2個の逆止爪26,27の領域から連鎖結束材10が消滅しても、残る結束材に緩みを発生させないのである。 In FIG. 7 continued from FIG. 5 described above, the two feeding claws 26 and 27 are simultaneously advanced in the feeding direction of the chain binding material 10, and the reverse movements are alternately operated to check the chain binding material 10. Prevent loosening. When the sensor 59 installed on the cover 21 detects the end of the chain binding material 10 being transferred, an alarm 60 is transmitted. In this case, the foremost check pawl 61 includes the two rear end check claws 26, Even if the chain binding material 10 disappears from the region 27, the remaining binding material is not loosened.
図6は、前記の連鎖結束材を拡大して示すもので、両サイド2本の帯15間に既に図11において説明した結束材10を縦列状に配置すると共に、各結束材10の両端それぞれを繋ぎ材16を介し前記帯15に連結する。なお前記帯15に等間隔に形成した穴17は、この穴に爪車の爪を引っ掛けて運搬可能にする実施例を示したものである。 FIG. 6 is an enlarged view of the chain binding material. The binding materials 10 already described in FIG. 11 are arranged in a column between the two strips 15 on both sides, and both ends of each binding material 10 are respectively shown. Is connected to the band 15 via the connecting material 16. In addition, the hole 17 formed in the said belt | band | zone 15 at equal intervals shows the Example which hooks the nail | claw of a claw wheel in this hole, and enables it to convey.
図7は、既に説明したトンネル軌道23の末端部分を示すもので、図8のように、前記の連鎖結束材10はトンネル軌道23に沿ってガイドプレート30の正面に向けて搬送され、当該ガイドプレート30において袋口を結束することになるが、図7における矢視線I方向から前記のガイドプレート30の背面を見ると、それは図1に示すごとく図示される。 FIG. 7 shows the end portion of the tunnel track 23 already described. As shown in FIG. 8, the chain binding material 10 is transported along the tunnel track 23 toward the front surface of the guide plate 30, and the guide The bag mouth is bound in the plate 30. When the back surface of the guide plate 30 is viewed from the direction of the arrow I in FIG. 7, it is illustrated as shown in FIG.
すなわち当該図1に示すガイドプレート30は、その前面のカバープレート31の大部分を削除して内部を表示するもので、縦方向に形成した溝型のリフトガイド32の下域に、フラットバーにより形成した昇降台座33を配置する一方、前記リフトガイド32に交差する軌道24に、閉鎖バー34を配置し、さらに一対の切断刃35と、結束材20の折り曲げ機構36とを配置する。 That is, the guide plate 30 shown in FIG. 1 deletes most of the front cover plate 31 and displays the inside thereof. A flat bar is provided below the groove-shaped lift guide 32 formed in the vertical direction. While the formed lift base 33 is disposed, a closing bar 34 is disposed on the track 24 intersecting with the lift guide 32, and a pair of cutting blades 35 and a bending mechanism 36 for the binding material 20 are disposed.
より具体的には、図10のごとく前記一対の切断刃35は、結束材両端と両サイドの帯15との間の繋ぎ材16をそれぞれカットする目的のもので、一方前記折り曲げ機構36は雄要素12を矢印39に沿って90度角だけ折り曲げるもので、前記の折り曲げ機構は操作レバー37と、プッシュ板38とにより構成している。 More specifically, as shown in FIG. 10, the pair of cutting blades 35 are for the purpose of cutting the connecting material 16 between both ends of the binding material and the bands 15 on both sides, while the bending mechanism 36 is male. The element 12 is bent by a 90-degree angle along the arrow 39, and the bending mechanism includes an operation lever 37 and a push plate 38.
つまり図2において前記両側一対の前記切断刃35の上動により、結束材10の両端繋ぎ材をカットする共に、レバー37と一体に回転するプッシュ板38の押力により雄要素12を起立させる。ただかかる作用は、図6において最先端の結束材10が一次セクション81に到達したときに行なうもので(雄要素12起立)、そのあと雄要素12起立のまま1ピッチだけ二次セクション82に移動する結束材10を、図3のごとく昇降台座33により上限まで押し上げ、図4のごとく開閉バー34の押し出しにより、前記雄要素12を雌要素10の上に被せるのである。 That is, in FIG. 2, both ends of the pair of cutting blades 35 are moved to cut both ends of the binding material 10, and the male element 12 is raised by the pressing force of the push plate 38 that rotates integrally with the lever 37. However, such an action is performed when the cutting edge binding material 10 reaches the primary section 81 in FIG. 6 (male element 12 standing), and then moves to the secondary section 82 by one pitch with the male element 12 standing. The binding material 10 to be pushed is pushed up to the upper limit by the elevating pedestal 33 as shown in FIG. 3, and the male element 12 is put on the female element 10 by pushing out the opening / closing bar 34 as shown in FIG.
図7で明らかなように、操作シリンダー40に支持した前記一対の切断刃35を、昇降台座33の手前の一次セクションに配置し、二次セクションにおいて動力機器41に支持した前記昇降台座33が、リフトガイド32に沿って結束材を上動させるのであるが、かかる作業工程は、図8における案内スリット45に沿って、捻った袋口を矢印46の方向から押し込む圧力をレバー47に作用させ、前記レバー47がセンサー48から離反しる際、前記センサー48が発する信号により開始するのである。 As apparent from FIG. 7, the pair of cutting blades 35 supported by the operation cylinder 40 is disposed in the primary section in front of the lifting platform 33, and the lifting platform 33 supported by the power device 41 in the secondary section includes: The binding material is moved up along the lift guide 32, but this work step is performed by applying a pressure to the lever 47 to push the twisted bag mouth from the direction of the arrow 46 along the guide slit 45 in FIG. When the lever 47 moves away from the sensor 48, it starts with a signal generated by the sensor 48.
すなわち前記図7において、包袋80の捻った袋口がレバー47に作用し前記センサーが信号を発信すると、一次セクションにおいて操作シリンダー40により動作する切断刃35が、両サイドの帯15から結束材10を分離すると共に、別個のシリンダー50は、図1の折り曲げ機構36を操作して結束材における雄要素12を起立させる。続いて図7における第1、第2の2個の送り爪26、27が同時前進して連鎖結束材10を1ピッチだけ送り出すと、二次セクションにおいて動力機41は昇降台座33でもって最先端の結束材10を上方の袋口に被せ、既に図4において説明したように、横から閉鎖バー34が突き出て結束材の雄要素12をさらに折り曲げる。 That is, in FIG. 7, when the twisted bag mouth of the wrapping bag 80 acts on the lever 47 and the sensor sends a signal, the cutting blade 35 operated by the operation cylinder 40 in the primary section is moved from the band 15 on both sides. While separating 10, a separate cylinder 50 operates the folding mechanism 36 of FIG. 1 to raise the male element 12 in the tie. Subsequently, when the first and second feeding claws 26 and 27 in FIG. 7 are simultaneously advanced to feed the chain-bound material 10 by one pitch, the power machine 41 in the secondary section is at the cutting edge with the lift base 33. The binding material 10 is put on the upper bag mouth, and as already described in FIG. 4, the closing bar 34 protrudes from the side to further bend the male element 12 of the binding material.
図13に示すように、昇降台座33は直列2連のシリンダー61,62を備え、これらシリンダーとポンプ68とを、符号1,3で示す2個のオン.オフ弁を介して連結する。初期起動においては、先ず符号1の弁の切換えにより、第1シリンダー61のピストン63が昇降台材33と共に結束材を、案内スリット45内の袋口の領域まで持ち上げ、つづいて符号2の弁の切り替えに伴うポンプ67の圧力により、第2シリンダー64のピストン65が閉鎖バー34を押し出し、前記袋口の周りで前記結束材を閉鎖する。そのあと符号3の弁の切換えにより、第3シリンダー62のピストン66が昇降台座33の上の結束材を、前記の閉鎖バー34の下面に押し付け、前記結束材の再挟圧により結束材における2個の鉤の係合をより確実にするのである。なお実施に当たっては、前記3本のシリンダー61,62,64に変更してカムを用いることもでき、2段カムで昇降台座33を2段階に押し上げることが可能である。 As shown in FIG. 13, the elevating pedestal 33 includes two cylinders 61 and 62 connected in series, and these cylinders and the pump 68 are connected to two ON. Connect through an off valve. In the initial start-up, first, by switching the valve 1, the piston 63 of the first cylinder 61 lifts the binding material together with the lifting / lowering base material 33 to the bag opening region in the guide slit 45, and subsequently the valve 2 of the reference 2. Due to the pressure of the pump 67 accompanying the switching, the piston 65 of the second cylinder 64 pushes out the closing bar 34 and closes the binding material around the bag mouth. After that, by switching the valve 3, the piston 66 of the third cylinder 62 presses the binding material on the elevating pedestal 33 against the lower surface of the closing bar 34, and 2 in the binding material by the re-squeezing pressure of the binding material. This makes the engagement of the individual hooks more reliable. In practice, a cam can be used instead of the three cylinders 61, 62, and 64, and the lift base 33 can be pushed up in two stages by the two-stage cam.
