【0004】
【発明が解決しようとする課題】
前記特許文献1記載のラベル貼付装置は、ラックに保持された管状容器(採血管)にラベルを貼付するので、予め管状容器をラックに収納する必要があり、収納作業に手間がかかっていた。
【0005】
そこで、ばらばら状態になっている複数本の管状容器の外周面へ、人手を煩わすことなく所定位置にラベルを貼付するために解決すべき技術的課題が生じてくるのであり、本発明はこの課題を解決することを目的とする。
【0006】
【課題を解決するための手段】
本発明は上記目的を達成するために提案されたものであり、ホッパーから投入された複数本の管状容器を一方向へ整列させる整列機構と、前記整列機構にて整列された管状容器を1本ずつ搬送機構へ供給する供給機構と、前記供給機構から供給された管状容器を1本ずつ保持する保持具を備え、該保持具に保持された管状容器がラベリングマシンの近傍を通過するように配置した搬送機構と、前記ラベリングマシンにて貼付されたラベルを管状容器の外周面に圧着するラベル圧着機構と、ラベルを貼付された管状容器を前記保持具から離脱させる離脱機構と、前記離脱機構の近傍へ管状容器の保持ラックを移動させる保持ラック移動機構とから構成された管状容器のラベル貼付装置、
及び、上記整列機構は、螺旋状の搬送路に管状容器を一方向へ整列させるように構成された管状容器のラベル貼付装置、
及び、上記供給機構は、整列機構から送られてくる管状容器の先頭の管状容器を一旦停止させるストッパと、該ストッパにより停止された先頭の管状容器を把持する供給チャックと、該供給チャックを搬送機構側へ移動させるシリンダと、該供給チャックを搬送機構側へ移動させたときに二番目の管状容器を把持して後続の管状容器を停止させるストッパチャックとからなり、前記シリンダの作動により供給チャックに保持された管状容器を搬送機構の保持具へ移動して保持させるように構成された管状容器のラベル貼付装置
及び、上記搬送機構に備えられた保持具は、管状容器を差し込んで保持できるように管状容器の内径よりもやや小径の円柱形状であり、且つ、無端帯の表面に所定間隔にて進行方向へ一列に配置された管状容器のラベル貼付装置、
及び、上記搬送機構は、無端帯が下向き面から上向き面に反転する回転領域で略水平状態になった保持具にて供給機構から管状容器が供給され、無端帯の上向き面の保持具にて管状容器がラベリングマシンの近傍を通過するとともにラベル圧着機構にてラベルが圧着されるように構成された管状容器のラベル貼付装置、
及び、上記ラベル圧着機構は、保持具に保持された管状容器の外周面に圧接し且つ無端帯の進行方向に沿って回転するベルトと、該ベルトに対峙して前記保持具の反対側に設けられた反力受け板とから構成された管状容器のラベル貼付装置、
及び、上記離脱機構は、搬送機構の終端部近傍で且つ無端帯が上向き面から下向き面に反転した直後の保持具近傍に設けられ、下向きの保持具から管状容器内へエアを噴出して管状容器を落下させるように構成された管状容器のラベル貼付装置、
及び、上記保持ラック移動機構は、所定本数の管状容器を起立した状態で収納可能な空の保持ラックを供給する供給用無端帯と、所定本数の管状容器を収納した後の保持ラックを排出する排出用無端帯とを備え、前記供給用無端帯にて供給された空の保持ラックを離脱機構の下方位置へ移動させ、保持具から離脱した管状容器を順次1本ずつ収納すべく保持ラックを間欠的に移動し、所定本数の管状容器を収納した保持ラックを前記排出用無端帯へ移動させるように構成された管状容器のラベル貼付装置を提供するものである。
【0007】
【発明の実施の形態】
以下、本発明の一実施の形態を図面に従って詳述する。図1及び図2に示すように、試験管等の管状容器のラベル貼付装置10は、複数本の管状容器を一方向へ整列させる整列機構20と、前記整列機構20にて整列された管状容器を1本ずつ後述の搬送機構40へ供給する供給機構30と、前記供給機構30から供給された管状容器を1本ずつ保持する保持具41を備え、該保持具41に保持された管状容器がラベリングマシン50の近傍を通過するように配置した搬送機構40と、前記ラベリングマシン50にて貼付されたラベルを管状容器の外周面に圧着するラベル圧着機構60と、ラベルを貼付された管状容器を前記保持具41から離脱させる離脱機構70と、前記離脱機構70の近傍へ管状容器の保持ラック81を移動させる保持ラック移動機構80とから構成されている。
【0008】
図1乃至図3に示すように、前記整列機構20はホッパー21と円形のボウル22とバイブレータ23とからなり、ボウル22の内周には螺旋状の搬送路24が設けられている。該搬送路24はボウル22の中央部から外周に向けて徐々に高位置となるように傾斜している。また、ボウル22はバイブレータ23により振動しており、前記ホッパー21から投入された複数本の管状容器11,11…は、ボウル22の中央部に受け入れられた後、振動によって前記搬送路24上で一方向に整列されながら後段の供給機構30へ送られる。尚、逆向きで搬送路24を上がってきた管状容器11は図示しないセンサにて検知され、供給機構30へ送られる前にリジェクト装置(図示せず)によりボウル22へ送り返される。
【0009】
図4に示すように、前記供給機構30は搬送機構40の始端部近傍に設けられ、前段の整列機構20から送られてくる管状容器11,11…のうち先頭の管状容器(同図では符号11a)を一旦停止させるストッパ31と、該ストッパ31により停止された先頭の管状容器11aを把持する供給チャック32と、供給チャック32が後述する保持具41に差し込み操作を行っている間、二番目の管状容器(同図では符号11b)を把持して後続の管状容器11,11…が動かないように把持するストッパチャック33と、前記供給チャック32を後段の搬送機構40側へ移動させ、また、移動後に再び供給チャック32を元の位置へ引き戻すシリンダ34とからなる。
【0010】
後述するように、搬送機構40には無端帯42の表面に所定間隔にて保持具41,41…が設けられており、該保持具41は管状容器11を差し込んで保持できるように、管状容器11の内径よりもやや小径(具体的には管状容器11の内径の90〜99.9%の外径)の円柱形状となっている。該保持具41の中心部には、後述するようにエアを噴出するために、前記無端帯42を貫通して保持具41の先端部まで貫通するエア挿通孔41aが開穿されている。また、チェーン43の駆動によりスプロケット44aが同図(b)に於いて時計回りに回転し、無端帯42の上向き面が保持具41,41…と一体に図中矢印X方向へ移動していくように構成されている。尚、本実施の形態では、同図(c)に示すように、所謂トップチェーンと称される無端帯42を使用しており、その表面に所定間隔毎にて前記保持具41,41…が設けられている。
【0011】
そして、前記供給チャック32とストッパチャック33が夫々一番目の管状容器11aと二番目の管状容器11bとを把持して待機状態となり、前記保持具41が略水平状態になったとき(同図では41b)に、前記チェーン43の駆動を一旦停止して前記保持具41bの姿勢を水平状態に保持する。
【0012】
斯かる状態で、図5に示すように、前記ストッパ31を引き込んだ後に前記シリンダ34を伸長作動させ、供給チャック32を搬送機構40側へ移動する。従って、供給チャック32に保持された先頭の管状容器11aが、前記水平状態の保持具41bに差し込まれる。続いて、前記供給チャック32の保持を開放して前記シリンダ34を収縮作動させれば、前記水平状態の保持具41bに差し込まれた管状容器11aは該保持具41bに保持される。これと同時に、前記チェーン43の駆動を再開して無端帯42を動かし、管状容器11aを保持した水平状態の保持具41bを無端帯42の上向き面へ移動する。斯くして、再び図4に示した次工程への待機状態となる。
【0013】
搬送機構40は、図1及び図2に示したように、駆動装置であるギヤードモータ45の回転力をインデックス46及び伝動ベルト47を介してスプロケット44bへ伝達し、チェーン43を駆動して無端帯42の上向き面が保持具41,41…と一体に図中右方向へ間欠的に移動していくように構成されている。従って、前段の供給機構30から供給された管状容器11は、保持具41にて保持されつつ図中右方向へ間欠的に搬送され、ラベリングマシン50の近傍を通過する。
【0014】
図6及び図7に示すように、前記ラベリングマシン50はラベル51を仮着した帯状台紙52の原反ロール53を保持するロール支持軸54と、該ロール支持軸54に保持された前記原反ロール53から帯状台紙52を繰り出すための繰り出しローラ55と、帯状台紙52を繰り出しローラ55にニップするニップローラ56と、繰り出しローラ55によって繰り出される帯状台紙52の繰り出し方向を鋭角に転じることによりラベル51を帯状台紙52から剥がすためのピールプレート57と、ラベル51が剥がされた後の帯状台紙52を巻き取るための巻き取り軸58により構成され、モータ59によって繰り出しローラ55と巻き取り軸58が同時に回転するように構成されている。尚、巻き取り軸58側は滑りベルトであるため、ラベル51が剥がされた後の帯状台紙52を繰り出しローラ55と同時に巻き取って、帯状台紙52の巻き取り径が大きくなっても、ベルトとプーリ間が滑ることで対応できる。
【0015】
前記原反ロール53から繰り出された帯状台紙52はピールプレート57の先端部で鋭角的に折り返されるため、該帯状台紙52に仮着されたラベル51は、ピールプレート57の一側面に沿って直線上に進行しながら、帯状台紙52から剥離しつつ管状容器11の所定位置に所謂初期タッチしてその一端部が貼付される。前記無端帯42の移動速度と帯状台紙52の繰り出し速度が同速度となるように設定してあるので、ラベル51の一端部が貼付された状態で管状容器11が搬送方向(矢印X方向)へ移動し、ラベル51が剥がされた後の帯状台紙52はピールプレート57で折り返されて前記巻き取り軸58に巻き取られる。
【0016】
このように、前記保持具41に保持された管状容器11の所定位置に前記ラベリングマシン50にてラベル51の一端部が貼付された後、該管状容器11は搬送機構40によって矢印X方向へ間欠的に移動しながら、後段のラベル圧着機構60へ搬送される。
【0017】
図8に示すように、ラベル圧着機構60は、二つのプーリ61,62間に卷装されたベルト63と、該ベルト63に対峙して前記保持具41の反対側に設けられた反力受け板64とからなり、該ベルト63は前記保持具41に保持された管状容器11の外周面に圧接し、モータ65の駆動によりプーリ61が回転して該ベルト63が無端帯42の進行方向(矢印X方向)に沿って回転するように構成されている。また、該ベルト63の走行速度は前記無端帯42の走行速度よりも速くなるように設定されている。尚、符号66はベルト63の凹みを抑える薄板である。
【0018】
而して、ラベル51の一端部が貼付された管状容器11が、ラベル圧着機構60に搬送されて管状容器11の外周面に前記ベルト63が圧接したときに、管状容器11の搬送速度よりも前記ベルト63の走行速度が速いため、前記ベルト63に摺擦されて管状容器11が保持具41を中心に図中反時計回りに回転する。このとき、前記ラベル51がベルト63に圧接しながら管状容器11に巻き込まれ、該ラベル51はその全面に亙って均一に管状容器11の外周面へ貼付される。尚、前記搬送機構40の無端帯42が間欠的に停止したときは、ラベル圧着機構60のベルト63もこれに同期して停止するように構成されている。
【0019】
図9に示すように、前記離脱機構70は搬送機構40の終端部近傍に設けられ、前記無端帯42が上向き面から下向き面に反転した直後の保持具(同図では41c)近傍に設けられたエアマニホールド71と、前述したように無端帯42から保持具41cの中心部に貫通しているエア挿通孔41aとが一致したときに、エアポンプ(図示せず)にて圧縮されたエアを該下向きの保持具41cのエア挿通孔41aから管状容器(同図では11c)内へ噴出するように構成されている。離脱機構70の近傍には保持ラック移動機構80が設けられており、前記下向きの保持具41cの鉛直下方位置に保持ラック81が供給されている。尚、保持具41が上向きから下向きに反転する回転領域には、管状容器11が外れないように湾曲したガイド48が設けられている。
【0020】
図10に示すように、前記保持ラック81には管状容器11を起立した状態で収納可能な保持孔81aが所定数設けられており、この保持孔81aの開口周縁には斜め下向きに弾性部材からなる舌片81bが設けられ、保持孔81aに入った管状容器11が簡単には抜けないようになっているため、管状容器11の自然落下では保持孔81aに入りきらない。そこで、前記エアマニホールド71と下向きの保持具41cのエア挿通孔41aとが一致したときに、エアマニホールド71のエアがエア挿通孔41aを通って管状容器11内へ噴出されるので、ラベル51を貼付した管状容器11が下方へ押されて落下し、同図の二点鎖線で示すように、保持ラック81の一番目の保持孔81a内へ収納される。
【0021】
尚、搬送機構40の無端帯42は間欠的に動いているので、前記供給機構30で管状容器11を保持具41に差し込むためにチェーン43の駆動を一旦停止した位置が、前記エアマニホールド71と下向きの保持具41cのエア挿通孔41aとが一致するように構成されているため、前記下向きの保持具41cから管状容器11が正確に鉛直方向へ落下し、保持ラック81の保持孔81a内へ確実に収納されるように構成されている。
【0022】
然る後は、搬送機構40の無端帯42の動きが再開するので、管状容器11が離脱した保持具41は次の位置へ移動し、図11に示すように、無端帯42の下向き面に新たな管状容器11を保持した次の保持具41が移動するとともに、後述するように、保持ラック移動機構80の作動により保持ラック81が図中左方向へ移動し、前記管状容器11を収納した一番目の保持孔81aに隣接して設けられている二番目の保持孔81aが離脱機構70の鉛直下方位置に移動する。以下、同様の工程を繰り返して、保持ラック81に設けられた全ての保持孔81a,81a…に所定本数の管状容器11,11…を収納する。
【0023】
図12に示すように、前記保持ラック81の底面には長手方向にガイド溝81cが設けられ、このガイド溝81cは後述する保持ラック移動機構80のガイドリブ82に係合している。また、前記保持ラック81の前記搬送機構40に向いている側の下部に係合用の凹部81dが設けられ、後述するピッチ送り用ベルト83の凸部83aがこの凹部81dに係合して、保持ラック81をガイドリブ82に沿って図中矢印Y方向へ移動させるように形成されている。
【0024】
図13に示すように、前記保持ラック移動機構80は、空の保持ラック81を供給する供給用無端帯84と、前述した離脱機構70から離脱した管状容器11を所定本数収納した後の保持ラック81を外部へ排出する排出用無端帯85とを備えている。供給用無端帯84の終端部近傍には横送り部86が設けられ、供給されてくる空の保持ラック81,81…の前から二番目の保持ラック(同図では符号81B)をストッパシリンダ87の伸張作動にて一旦停止させ、一番先頭の保持ラック(同図では符号81A)のみを横送り部86に搬送する。
【0025】
前記横送り部86には、先頭の保持ラック81Aの外側(同図中右側)に横移送シリンダ88が設けられており、該保持ラック81Aの左側には前述したガイドリブ82を敷設してある。白抜き矢印で示した位置は、前述した離脱機構70の鉛直下方位置であり、前記保持具41から離脱した管状容器11を保持ラック81の保持孔81aへ収納する位置である。また、前述したピッチ送り用ベルト83は二つのプーリ89,90間に卷装され、モータ91によりプーリ90が時計回りに回転して、前記ガイドリブ82側のベルト面が矢印Y方向へ走行する。更に、排出用無端帯85の始端側には排出用シリンダ92が設けられている。
【0026】
供給用無端帯84で搬送されてきた先頭の保持ラック81Aは、同図の二点鎖線で示すように、前記横移送シリンダ88の伸長作動により、図13中左方向へ押し出され、図12にて説明したように、その底面に設けたガイド溝81cがガイドリブ82に係合して矢印Y方向へ移動する。また前記ピッチ送り用ベルト83が回転して、その凸部83aが保持ラック81Aの凹部81dに係合する。従って、前記ピッチ送り用ベルト83の駆動により、該保持ラック81Aがガイドリブ82に沿って更に矢印Y方向へ移動する。
【0027】
そして、図14に示すように、該保持ラック81Aの一番目の保持孔81aが離脱機構70の鉛直下方位置に移動したときに、前記モータ91の回転を停止して、ピッチ送り用ベルト83の駆動を停止する。また、横移送シリンダ88が収縮作動して元の状態に復帰する。
【0028】
図15に示すように、ピッチ送り用ベルト83の駆動を停止した状態で、前述したように、前記保持具41から離脱した管状容器11を保持ラック81Aの一番目の保持孔81aへ収納する。また、前記ストッパシリンダ87を収縮作動して、供給用無端帯84から供給された新たな保持ラック81Bを一つだけ横送り部86に搬送する。
【0029】
次に、前記ピッチ送り用ベルト83を保持ラック81Aの各保持孔81a,81a間のピッチに相当する距離だけ矢印Y方向へ駆動し、同図の二点鎖線で示すように、保持ラック81Aの二番目の保持孔81aが離脱機構70の鉛直下方位置に移動したときに、ピッチ送り用ベルト83の駆動を停止する。この状態で、前述と同様に前記保持具41から離脱した管状容器11を保持ラック81Aの二番目の保持孔81aへ収納する。
【0030】
以下、同様の工程を繰り返して、保持ラック81Aを各保持孔81a,81a間のピッチに相当する距離だけ矢印Y方向へ間欠的に移動させながら、図16に示すように、最後の保持孔81aに管状容器11を収納する。保持ラック81Aの各保持孔81a,81a…に所定本数の管状容器11,11…を収納した後に、前記ピッチ送り用ベルト83を駆動し、同図の二点鎖線で示すように、前記保持ラック81Aがガイドリブ82から外れて排出用無端帯85の始端部に至る位置まで、該保持ラック81Aを移動させる。
【0031】
図17に示すように、ピッチ送り用ベルト83の駆動を停止した状態で前記排出用シリンダ92を伸長駆動し、二点鎖線で示すように、所定本数の管状容器11、11…を収納した保持ラック81Aを排出用無端帯85へ移動させる。そして、前記排出用シリンダ92を収縮駆動して元の状態に復帰させる。然る後に、前記横移送シリンダ88を伸長駆動して、横送り部86に待機している新たな空の保持ラック81Bを図17中左方向へ移送し、前述と同様に、ピッチ送り用ベルト83を駆動して、その凸部83aを保持ラック81Bの凹部81dに係合させる。
【0032】
そして、図18に示すように、前記排出用無端帯85の駆動により、所定本数の管状容器11、11…を収納した保持ラック81Aを外部へ排出する。また、前述と同様の工程を繰り返して、新たな保持ラック18Bへ順次管状容器11を収納していく。
【0033】
尚、本発明は、本発明の精神を逸脱しない限り種々の改変を為すことができ、そして、本発明が該改変されたものに及ぶことは当然である。

[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 and 2, a labeling device 10 for a tubular container such as a test tube includes an alignment mechanism 20 for aligning a plurality of tubular containers in one direction, and a tubular container aligned by the alignment mechanism 20. A supply mechanism 30 that supplies the tubular containers one by one to a transport mechanism 40 described below, and a holder 41 that holds the tubular containers supplied from the supply mechanism 30 one by one. A transport mechanism 40 arranged so as to pass near the labeling machine 50, a label crimping mechanism 60 for crimping the label affixed by the labeling machine 50 to the outer peripheral surface of the tubular container, and a tubular container affixed with the label. A detaching mechanism 70 for detaching from the holder 41 and a holding rack moving mechanism 80 for moving the holding rack 81 of the tubular container to the vicinity of the detaching mechanism 70 are provided.
[0008]
As shown in FIGS. 1 to 3, the alignment mechanism 20 includes a hopper 21, a circular bowl 22, and a vibrator 23, and a spiral conveyance path 24 is provided on the inner periphery of the bowl 22. The transport path 24 is inclined so as to gradually increase in height from the center of the bowl 22 toward the outer periphery. The bowl 22 is vibrated by a vibrator 23, and the plurality of tubular containers 11, 11... Introduced from the hopper 21 are received in the center of the bowl 22 and then vibrated on the transport path 24 by the vibration. While being aligned in one direction, it is sent to the subsequent supply mechanism 30. Note that the tubular container 11 that has moved up the transport path 24 in the opposite direction is detected by a sensor (not shown), and is sent back to the bowl 22 by a reject device (not shown) before being sent to the supply mechanism 30.
[0009]
As shown in FIG. 4, the supply mechanism 30 is provided in the vicinity of the start end of the transport mechanism 40, and is the first tubular container (reference numeral in FIG. 4) among the tubular containers 11, 11... 11a), a supply chuck 32 for gripping the leading tubular container 11a stopped by the stopper 31, and a second while the supply chuck 32 is inserted into a holder 41 described later. The stopper chuck 33 for gripping the tubular container (reference numeral 11b in the figure) and holding the subsequent tubular containers 11, 11... So as not to move, and the supply chuck 32 are moved to the subsequent transport mechanism 40 side. And a cylinder 34 for returning the supply chuck 32 to its original position after the movement.
[0010]
As will be described later, holders 41, 41... Are provided at predetermined intervals on the surface of the endless belt 42 in the transport mechanism 40. The holder 41 is a tubular container so that the tubular container 11 can be inserted and held. 11 has a column shape slightly smaller than the inner diameter (specifically, an outer diameter of 90 to 99.9% of the inner diameter of the tubular container 11). At the center of the holder 41, an air insertion hole 41a is formed to penetrate the endless band 42 and penetrate to the tip of the holder 41 in order to eject air as described later. By driving the chain 43, the sprocket 44a rotates clockwise in FIG. 4B, and the upward surface of the endless belt 42 moves in the direction of the arrow X integrally with the holders 41, 41. It is configured as follows. In this embodiment, as shown in FIG. 3C, an endless band 42 called a so-called top chain is used, and the holders 41, 41,. Is provided.
[0011]
Then, when the supply chuck 32 and the stopper chuck 33 grip the first tubular container 11a and the second tubular container 11b, respectively, and are in a standby state, and the holder 41 is in a substantially horizontal state (in FIG. In 41b), the driving of the chain 43 is temporarily stopped, and the posture of the holder 41b is held in a horizontal state.
[0012]
In this state, as shown in FIG. 5, after the stopper 31 is retracted, the cylinder 34 is extended and the supply chuck 32 is moved to the transport mechanism 40 side. Therefore, the leading tubular container 11a held by the supply chuck 32 is inserted into the horizontal holder 41b. Subsequently, when the holding of the supply chuck 32 is released and the cylinder 34 is contracted, the tubular container 11a inserted into the holding member 41b in the horizontal state is held by the holding member 41b. At the same time, the driving of the chain 43 is restarted to move the endless belt 42, and the holder 41b in a horizontal state holding the tubular container 11a is moved to the upward surface of the endless belt 42. In this way, the process returns to the standby state for the next step shown in FIG.
[0013]
As shown in FIGS. 1 and 2, the transport mechanism 40 transmits the rotational force of the geared motor 45, which is a driving device, to the sprocket 44b via the index 46 and the transmission belt 47, drives the chain 43, and drives the endless belt. The upward surface 42 is configured to intermittently move rightward in the figure together with the holders 41, 41. Therefore, the tubular container 11 supplied from the preceding supply mechanism 30 is intermittently transported rightward in the figure while being held by the holder 41, and passes near the labeling machine 50.
[0014]
As shown in FIGS. 6 and 7, the labeling machine 50 includes a roll supporting shaft 54 for holding a raw roll 53 of a band-shaped backing 52 to which a label 51 is temporarily attached, and the raw material held on the roll supporting shaft 54. A feeding roller 55 for feeding the band-shaped backing sheet 52 from the roll 53, a nip roller 56 for nipping the band-shaped backing sheet 52 with the feeding roller 55, and a label 51 by turning the feeding direction of the band-shaped backing sheet 52 fed by the feeding roller 55 to an acute angle. It comprises a peel plate 57 for peeling off the band-shaped backing material 52 and a winding shaft 58 for winding up the band-shaped backing material 52 after the label 51 has been peeled off. The motor 59 rotates the feeding roller 55 and the winding shaft 58 simultaneously. It is configured to Since the take-up shaft 58 side is a sliding belt, the band-shaped backing sheet 52 from which the label 51 has been peeled off is taken up at the same time as the feeding roller 55, so that even if the winding diameter of the band-shaped backing sheet 52 becomes large, the belt-shaped backing sheet 52 is not removed. This can be handled by slipping between the pulleys.
[0015]
Since the band-shaped backing sheet 52 unwound from the web roll 53 is sharply folded at the tip of the peel plate 57, the label 51 temporarily attached to the band-shaped backing sheet 52 is straightened along one side of the peel plate 57. While moving upward, the so-called initial touch is made on a predetermined position of the tubular container 11 while being peeled off from the band-shaped mount 52, and one end thereof is attached. Since the moving speed of the endless band 42 and the feeding speed of the band-shaped backing sheet 52 are set to be the same speed, the tubular container 11 is moved in the transport direction (the direction of the arrow X) with one end of the label 51 attached. The band-shaped backing sheet 52 after the movement and the removal of the label 51 are folded back by the peel plate 57 and wound around the winding shaft 58.
[0016]
After one end of the label 51 is attached to the predetermined position of the tubular container 11 held by the holder 41 by the labeling machine 50, the tubular container 11 is intermittently moved in the direction of arrow X by the transport mechanism 40. While being moved, it is transported to the subsequent label pressure bonding mechanism 60.
[0017]
As shown in FIG. 8, the label pressure bonding mechanism 60 includes a belt 63 wound between two pulleys 61 and 62, and a reaction force receiving member provided on the opposite side of the holder 41 so as to face the belt 63. The belt 63 is pressed against the outer peripheral surface of the tubular container 11 held by the holder 41, and the pulley 61 is rotated by the driving of the motor 65 to move the belt 63 in the traveling direction of the endless belt 42 ( It is configured to rotate along the arrow X direction). The running speed of the belt 63 is set to be higher than the running speed of the endless belt 42. Reference numeral 66 denotes a thin plate that suppresses the dent of the belt 63.
[0018]
Thus, when the tubular container 11 to which one end of the label 51 is attached is conveyed to the label pressure bonding mechanism 60 and the belt 63 is pressed against the outer peripheral surface of the tubular container 11, the conveying speed of the tubular container 11 is lower than the conveying speed. Since the traveling speed of the belt 63 is high, the tubular container 11 is rubbed against the belt 63 and rotates counterclockwise around the holder 41 in the figure. At this time, the label 51 is wound around the tubular container 11 while being pressed against the belt 63, and the label 51 is uniformly attached to the outer peripheral surface of the tubular container 11 over the entire surface. When the endless belt 42 of the transport mechanism 40 stops intermittently, the belt 63 of the label pressure bonding mechanism 60 also stops in synchronization with this.
[0019]
As shown in FIG. 9, the detachment mechanism 70 is provided near the terminal end of the transport mechanism 40, and is provided near a holder (41c in FIG. 9) immediately after the endless belt 42 is inverted from the upward surface to the downward surface. When the air manifold 71 matches the air insertion hole 41a penetrating from the endless band 42 to the center of the holder 41c as described above, the air compressed by the air pump (not shown) is supplied to the air manifold 71. It is configured such that it is ejected from the air insertion hole 41a of the downward holding tool 41c into the tubular container (11c in the same figure). A holding rack moving mechanism 80 is provided near the detaching mechanism 70, and a holding rack 81 is supplied to a position vertically below the downward holding tool 41c. Note that a curved guide 48 is provided in the rotation area where the holder 41 is inverted from upward to downward so that the tubular container 11 does not come off.
[0020]
As shown in FIG. 10, the holding rack 81 is provided with a predetermined number of holding holes 81a capable of storing the tubular container 11 in an upright state, and the periphery of the opening of the holding hole 81a is inclined obliquely downward from an elastic member. Since the tongue piece 81b is provided so that the tubular container 11 that has entered the holding hole 81a does not easily come off, the tubular container 11 cannot fall into the holding hole 81a by natural fall. Therefore, when the air manifold 71 and the air insertion hole 41a of the downward holder 41c coincide with each other, the air of the air manifold 71 is blown into the tubular container 11 through the air insertion hole 41a, so that the label 51 is The attached tubular container 11 is pushed downward and falls, and is stored in the first holding hole 81a of the holding rack 81 as shown by a two-dot chain line in FIG.
[0021]
Since the endless belt 42 of the transport mechanism 40 is intermittently moving, the position where the driving of the chain 43 is temporarily stopped in order to insert the tubular container 11 into the holder 41 by the supply mechanism 30 is the position where the air manifold 71 is Since the air insertion hole 41a of the downward holding tool 41c is configured to coincide with the air insertion hole 41a, the tubular container 11 falls exactly vertically from the downward holding tool 41c and enters the holding hole 81a of the holding rack 81. It is configured to be securely housed.
[0022]
After that, since the movement of the endless belt 42 of the transport mechanism 40 resumes, the holding tool 41 from which the tubular container 11 has been separated moves to the next position, and as shown in FIG. As the next holder 41 holding the new tubular container 11 moves, as described later, the holding rack 81 is moved leftward in the figure by the operation of the holding rack moving mechanism 80, and the tubular container 11 is stored. The second holding hole 81a provided adjacent to the first holding hole 81a moves to a position vertically below the detachment mechanism 70. Hereinafter, by repeating the same process, a predetermined number of tubular containers 11 are stored in all the holding holes 81a provided in the holding rack 81.
[0023]
As shown in FIG. 12, a guide groove 81c is provided on the bottom surface of the holding rack 81 in the longitudinal direction, and the guide groove 81c is engaged with a guide rib 82 of a holding rack moving mechanism 80 described later. An engaging recess 81d is provided at a lower portion of the holding rack 81 on the side facing the transport mechanism 40, and a convex portion 83a of a pitch feed belt 83 described later engages with the concave portion 81d to hold. The rack 81 is formed so as to move in the arrow Y direction in the figure along the guide rib 82.
[0024]
As shown in FIG. 13, the holding rack moving mechanism 80 includes a supply endless band 84 for supplying an empty holding rack 81 and a holding rack after storing a predetermined number of tubular containers 11 detached from the detachment mechanism 70 described above. And a discharge endless belt 85 for discharging the outside 81 to the outside. A lateral feed portion 86 is provided near the end of the supply endless band 84, and a second holding rack (reference numeral 81B in the figure) from the front of the supplied empty holding racks 81, 81. Is temporarily stopped by the extension operation, and only the foremost holding rack (reference numeral 81A in the figure) is conveyed to the lateral feed unit 86.
[0025]
The lateral feed portion 86 is provided with a lateral transfer cylinder 88 outside (the right side in the figure) the leading holding rack 81A, and the above-described guide rib 82 is laid on the left side of the holding rack 81A. The position indicated by the white arrow is the position vertically below the detachment mechanism 70 described above, and is the position where the tubular container 11 detached from the holder 41 is stored in the holding hole 81a of the holding rack 81. Further, the above-mentioned pitch feed belt 83 is wound around the two pulleys 89 and 90, and the pulley 90 is rotated clockwise by the motor 91, so that the belt surface on the guide rib 82 side runs in the arrow Y direction. Further, a discharge cylinder 92 is provided at the start end of the endless discharge belt 85.
[0026]
The leading holding rack 81A conveyed by the supply endless belt 84 is pushed leftward in FIG. 13 by the extension operation of the horizontal transfer cylinder 88, as shown by the two-dot chain line in FIG. As described above, the guide groove 81c provided on the bottom surface engages with the guide rib 82 and moves in the arrow Y direction. Further, the pitch feed belt 83 rotates, and the convex portion 83a engages with the concave portion 81d of the holding rack 81A. Accordingly, the driving of the pitch feed belt 83 causes the holding rack 81A to move further along the guide ribs 82 in the arrow Y direction.
[0027]
Then, as shown in FIG. 14, when the first holding hole 81a of the holding rack 81A moves to a position vertically below the detachment mechanism 70, the rotation of the motor 91 is stopped and the pitch feed belt 83 is stopped. Stop driving. Further, the lateral transfer cylinder 88 contracts and returns to the original state.
[0028]
As shown in FIG. 15, while the driving of the pitch feed belt 83 is stopped, as described above, the tubular container 11 detached from the holder 41 is stored in the first holding hole 81a of the holding rack 81A. Further, the stopper cylinder 87 is contracted to convey only one new holding rack 81 </ b> B supplied from the supply endless belt 84 to the lateral feed unit 86.
[0029]
Next, the pitch feed belt 83 is driven in the direction of arrow Y by a distance corresponding to the pitch between the holding holes 81a, 81a of the holding rack 81A, and as shown by the two-dot chain line in FIG. When the second holding hole 81a moves to a position vertically below the release mechanism 70, the driving of the pitch feed belt 83 is stopped. In this state, the tubular container 11 detached from the holding tool 41 is stored in the second holding hole 81a of the holding rack 81A as described above.
[0030]
Hereinafter, the same process is repeated to intermittently move the holding rack 81A in the direction of the arrow Y by a distance corresponding to the pitch between the holding holes 81a, 81a, as shown in FIG. The tubular container 11 is housed. After a predetermined number of tubular containers 11, 11... Are stored in the holding holes 81a, 81a... Of the holding rack 81A, the pitch feed belt 83 is driven, and as shown by a two-dot chain line in FIG. The holding rack 81A is moved to a position where 81A is disengaged from the guide rib 82 and reaches a start end of the endless belt 85 for discharge.
[0031]
As shown in FIG. 17, while the drive of the pitch feed belt 83 is stopped, the discharge cylinder 92 is extended and driven to hold a predetermined number of tubular containers 11, 11... As shown by a two-dot chain line. The rack 81A is moved to the endless belt 85 for discharge. Then, the discharge cylinder 92 is contracted and returned to the original state. After that, the horizontal transfer cylinder 88 is extended and driven to transfer a new empty holding rack 81B waiting at the horizontal feed unit 86 to the left in FIG. By driving 83, the convex portion 83a is engaged with the concave portion 81d of the holding rack 81B.
[0032]
Then, as shown in FIG. 18, the holding rack 81A containing the predetermined number of tubular containers 11, 11... Is discharged to the outside by driving the discharge endless belt 85. Further, the same steps as described above are repeated, and the tubular containers 11 are sequentially stored in new holding racks 18B.
[0033]
The present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified ones.
