Description

【0001】
【発明の属する技術分野】
この発明は周壁を有する下箱(身)に周壁を有する蓋を被せて箱を形成する箱の組立装置に関するものである。
【0002】
【従来の技術】
下箱と蓋のツーピースで形成される箱、所謂、テレスコープ形の箱においては、下箱および蓋のそれぞれが相互に嵌合される周壁を有するため、下箱同士あるいは蓋同士を安定よく積み重ねることができない。
【0003】
このため、下箱に蓋を被せて箱を形成し、その箱を積み重ねて保管し、あるいは積み重ねた複数の箱を紐等で結束する状態でトラックにより輸送することが行なわれている。
【0004】
ここで、下箱および蓋は打抜きシートからの折曲げと接着により形成され、これを機械的に行なう成形用フォーマとして、特公昭51−26104号公報に記載されたものが従来から知られているが、その成形用フォーマによって連続的に形成された下箱に蓋を自動的に被せるようにした箱組立て装置は知られていない。
【0005】
そこで、従来では、人手によって下箱に蓋を被せるようにしており、非常に手間がかかっていた。
【0006】
特公昭55−10374号公報あるいは米国特許3138905号明細書には蓋の折曲げ成形と蓋被せとを同時に行なうことができるようにした蓋の形成装置が記載されている。
【0007】
上記蓋の形成装置においては、予め組立てられた下箱を昇降テーブル上に搬送し、その昇降テーブル上に蓋形成用素材としての打抜きシートを搬送して位置決めしたのち、昇降テーブルを上昇し、内部成形型として使用する下箱により打抜きシートを持ち上げて折曲げガイドから成る成形型内に打抜きシートを押し込むことにより、蓋の成形と蓋被せとを同時に行なうようにしている。
【0008】
【発明が解決しようとする課題】
ところで、上記蓋の形成装置においては、予め組立てられた下箱を蓋の内周成形用の内部成形型とするため、下箱に形成された周壁には強度が要求され、その周壁が単壁構造であると強度不足のため、蓋の成形時に下箱の周壁が内方に倒れて蓋を精度よく成形することができない場合が生じる。
【0009】
この発明の課題は、箱成形用フォーマによって形成された下箱に蓋成形用フォーマによって形成された蓋を自動的に被せるようにして箱をきわめて能率よく組立てることができるようにした箱の組立装置を提供することである。
【0010】
【課題を解決するための手段】
上記の課題を解決するために、この発明においては、周壁を上向きとする蓋を蓋搬送コンベヤによりホッパに向けて搬送する途中で上下を反転し、周壁が下向きとされた蓋をホッパ内の傾斜する底板上に供給し、一方、周壁を上向きとする下箱を下箱搬送コンベヤにより前記ホッパの下方を通過するよう搬送し、その下箱がホッパの下方を通過する際、下箱の前壁外面でホッパ内の蓋の前壁内面を押圧してホッパの前側下部に設けられた開口部から蓋を取り出し、蓋の自重による下降により下箱に蓋を被せるようにした箱の組立装置において、前記ホッパの下端と下箱搬送コンベヤの搬送面間に一対の板ばねを設け、その一対の板ばねは、その後端を下箱が通過できる間隔を開けて固定し、その先端を下箱の両側壁間の寸法より狭い間隔を開けた自由端としてホッパ内に積み重ねられた最下位の蓋の周壁の両側壁内に位置させるようハの字状で搬送方向に長くのびており、その先端は下箱が前記ホッパの下方まで搬送されると外側方に押し拡げられて前記最下位の蓋の周壁の側壁内面と前記下箱の周壁の外側壁間に挟まれるようにした構成を採用したのである。
【0011】
上記のように、蓋成形用フォーマによって形成された蓋を搬送中において上下を反転し、周壁が下向きとされた蓋をホッパ内に供給して傾斜状の底板で支持し、一方、箱成形用フォーマから排出される下箱をホッパの下方を通過するように搬送することにより、下箱の前壁外面はホッパ内の蓋の前壁内面を押圧してホッパの前側下部に設けられた開口部から蓋を取り出すことになり、その取り出された蓋は自重により下降して下箱の周壁に完全に嵌合するため、下箱の搬送中に蓋を自動的に被せることができ、箱をきわめて能率よく組立てることができる。
【0012】
【発明の実施の形態】
以下、この発明の実施の形態を図面に基づいて説明する。図1は箱組立て装置の概略図を示し、図2は図1の平面図を示す。この箱組立て装置は、蓋成形用フォーマAおよび下箱成形用フォーマBを有する。
【0013】
図3および図4に示すように、蓋成形用フォーマAは、蓋形成用素材としての打抜きシートS0 の両側縁を支持する一対のレール部材10を有している。
【0014】
ここで、打抜きシートS0 は底パネル1の外周に折曲げ線2を介して一対の側壁パネル3および一対の端壁パネル4を連設し、一対の側壁パネル3の両端に折曲げ線5を介して接続パネル6を連設している。
【0015】
一対のレール部材10で支持された打抜きシートS0 の上方には昇降動される押型11が設けられている。また、打抜きシートS0 の下方には一対の側壁パネル3と対応する位置に側壁折曲げガイド12と、一対の端壁パネル4と対応する位置に端壁折曲げガイド13と、接続パネル6と対応する位置に糊ロール14とが設けられている。
【0016】
上記蓋成形用フォーマAは、一対のレール部材10上に打抜きシートS0 を供給し、その打抜きシートS0 が位置決めされた停止状態で押型11を下降させ、その押型11が底パネル1を押圧する作用により打抜きシートS0 を押し下げ、その下降時に、糊ロール14との接触によって接続パネル6の下面に糊を塗布すると共に、その接続パネル6を上方に折曲げるようにしている。
【0017】
また、接続パネル6の折曲げ後、側壁折曲げガイド12との接触により側壁パネル3を上方に折曲げ、その側壁パネル3の折曲げ後、端壁折曲げガイド13との接触により端壁パネル4を上方に折曲げ、前記接続パネル6を端壁パネル4の内面に接着させて、周壁aを有する蓋Xを形成するようにしており、その蓋Xを下方に配置された図示省略の排出コンベヤによって蓋成形用フォーマAから排出するようにしている。
【0018】
なお、下箱成形用フォーマBは、蓋成形用フォーマAと同一の構成から成り、また、下箱形成用素材の打抜きシートの形状は蓋形成用の打抜きシートS0 と同一形状であってその打抜きシートS0 よりサイズが少し小さいだけであるため、下箱成形用フォーマBの説明および下箱形成用の打抜きシートの説明を省略する。上記下箱成形用フォーマBによって、図6で示すような単壁構造の周壁bを有する下箱Yが形成される。
【0019】
図1および図2に示すように、蓋成形用フォーマAから排出される周壁aを上向きとして上方に開口した蓋Xは蓋搬送コンベヤ20によりホッパ30に向けて搬送される。
【0020】
一方、下箱成形用フォーマBから排出される周壁bを上向きとして上方に開口した下箱Yは下箱搬送コンベヤ40によって前記ホッパ30の下方を通過するように搬送される。
【0021】
蓋搬送コンベヤ20は、上部コンベヤ21と、その下方に設けられた下部コンベヤ22とから成り、前記上部コンベヤ21は曲線形の第1コンベヤ21aの排出端に直線状の第2コンベヤ21bを接続している。
【0022】
下部コンベヤ22は直線状のベルトコンベヤから成る。この下部コンベヤ22は供給端部が第2コンベヤ21bの排出端の下方に位置し、かつ排出端がホッパ30の上部一側に位置する配置とされ、第2コンベヤ21bによって搬送される蓋Xの搬送方向と逆方向に蓋Xを搬送するようになっている。
【0023】
第2コンベヤ21bの排出端より前方には反転ガイド23が設けられている。反転ガイド23は第2コンベヤ21bより排出される蓋Xの搬送方向先端を下向きに誘導する傾斜部23aを上部に有し、この傾斜部23aの下端に連設された垂直部23bの下端が下部コンベヤ22の供給端部上に臨んでいる。
【0024】
第2コンベヤ21bから排出される蓋Xは反転ガイド23の傾斜部23aに先端が当接して下向きに誘導され、その先端が下部コンベヤ22の供給端部で受けられる状態で搬送方向の後端部が第2コンベヤ21bの排出端部に接触して傾斜状態とされ、その状態から下部コンベヤ22により蓋Xの下端部(底パネル1)が搬送される作用によって上下が反転される。この反転により周壁aが下向きとされ、下方に開口した状態とされた蓋Xは下部コンベヤ22によりホッパ30に供給される。
【0025】
図1および図2に示すように、下箱Yを搬送する下箱搬送コンベヤ40は、第1搬送コンベヤ41と、その先端に接続された第2搬送コンベヤ42とから成り、前記第2搬送コンベヤ42は前記ホッパ30を下方に通過するように配置されている。
【0026】
第1搬送コンベヤ41および第2搬送コンベヤ42のそれぞれはベルトコンベヤから成り、第2搬送コンベヤ42のベルト42aには幅方向に延びるリブ状の押圧部材42bがベルト42aの移動方向に等間隔に設けられ、前記第1搬送コンベヤ41から第2搬送コンベヤ42上に送り込まれる下箱Yは前記押圧部材42bにより搬送方向の後壁外面が押されてホッパ30の下方に向けて搬送される。
【0027】
図6および図7に示すように、ホッパ30は蓋Xの先端部(前壁外面)を位置決めする左右一対のフロントガイド31と、蓋Xの両側壁外面の前後部を位置決めする前後一対のサイドガイド32と、蓋Xを積み重ねた状態に支持する底板33とから成る。
【0028】
左右一対のフロントガイド31には、蓋Xの側壁外面の先端部を位置決めするサイドガイド32が一体に設けられている。このフロントガイド31の下端と第2搬送コンベヤ42の搬送面間には開口部34が設けられている。開口部34はフロントガイド31の下端に取付けたゲート35によって開閉される。
【0029】
ゲート35はピンヒンジ36によって開閉自在に支持され、そのピンヒンジ36に支持された図示省略のスプリングによって開口部34を閉じる方向に付勢されている。このゲート35は蓋Xが押し出される際、その蓋Xにより押圧されてホッパ30の前側に向けて揺動し、一つの蓋Xのみの通過を許容するようになっている。
【0030】
底板33はフロントガイド31に向けて下り勾配をもって傾斜し、その底板33によって蓋Xは周壁aの前壁内面が第2搬送コンベヤ42で搬送される下箱Yの搬送方向先端面(前壁外面)で押圧されるよう傾斜状に支持される。
【0031】
ホッパ30の下端と第2搬送コンベヤ42の搬送面間には左右一対の板ばね50が設けられている。一対の板ばね50は第2搬送コンベヤ42によって搬送される下箱Yの搬送方向にそれぞれ長くのび、これらの後端は下箱Yが通過できる間隔を開けて固定され、自由端であるこれらの先端部は下箱Yの両側壁間の寸法より狭い間隔でホッパ30内に積み重ねられた最下位の蓋Xの周壁aの両側壁内に位置している。このように、一対の板ばね50は第2搬送コンベヤ42によって搬送される下箱Yによって先端部が外側方に向けて押し拡げられるようなハの字状の傾斜状態に配置され、搬送されてくる前記下箱Yにより先端部が押し拡げられると、下箱Yの周壁bの側壁外面と蓋Xの周壁aの側壁内面間に先端部が臨み、下箱Yと蓋Xとを相対的に幅方向に位置決めするようになっている。
【0032】
ホッパ30の前側には、下箱Yに被せられた蓋Xを押圧する押え装置60が設けられている。押え装置60はホッパ30のフロントガイド31に取付けられたブラケット61に複数のローラアーム62の各一端部を回動自在に支持し、各ローラアーム62の他端部に押えローラ63を回動自在に取付け、この押えローラ63でその下方を通過する蓋Xを押さえるようにしている。64はローラアーム62の下方向の揺動量を制限するストッパを示す。
【0033】
実施の形態で示す箱の組立て装置は上記の構造から成り、蓋成形用フォーマAによって形成された蓋Xは周壁aを上向きとして上方へ開口した状態で上部コンベヤ21に送り出され、その上部コンベヤ21によって図1の矢印方向に搬送される。
【0034】
上部コンベヤ21によって搬送される蓋Xは第2コンベヤ21bの排出端からその下方に設けられた下部コンベヤ22の供給端部上に送り込まれる。このとき、蓋Xの先端部は反転ガイド23に案内されて下方に落下し、下部コンベヤ22によって先端が支持され、後端が第2コンベヤ21bの排出端に支持される傾斜状態から下部コンベヤ22により先端部が図1の矢印方向に搬送される作用によって上下が反転され、周壁aが下向きで下方へ開口した状態とされる。
【0035】
反転後の蓋Xは下部コンベヤ22により搬送されてホッパ30の上部から内部に送り込まれ、そのホッパ30の底板33により支持されて傾斜状とされ、その上に後続の蓋Xが積み重ねられる。
【0036】
一方、下箱成形用フォーマBによって形成された下箱Yは周壁bを上向きとして上方へ開口した状態で下箱搬送コンベヤ40の第1搬送コンベヤ41上に送り出され、その第1搬送コンベヤ41から第2搬送コンベヤ42の供給端部上に送り込まれる。
【0037】
第2搬送コンベヤ42上に送り込まれた下箱Yは押圧部材42bにより搬送方向の後端面(後壁外面)が押圧されてホッパ30の下方に向けて搬送される。下箱Yがホッパ30の下方まで搬送され、左右一対の板ばね50の先端部間に侵入すると、一対の板ばね50の自由端となっている先端部は外側方に押し拡げられる。このとき、板ばね50の先端部はホッパ30内に位置する最下位の蓋Xの周壁aの側壁内面と下箱Yの周壁bの外側壁間に挟まれる状態とされ、最下位の蓋Xと下箱Yは幅方向に位置決めされる。
【0038】
下箱Yが第2搬送コンベヤ42によってさらに前方に搬送されると、下箱Yの搬送方向先端面(前壁外面)がホッパ30内に位置する最下位の蓋Xの周壁aの前壁内面に当接して周壁aを押圧する。
【0039】
このため、最下位の蓋Xは図8(I)に示すように、フロントガイド31の下端の開口部34からホッパ30の外部に押し出される。
【0040】
最下位の蓋Xの搬送方向後端(後壁)が板ばね50の先端を通過する位置まで蓋Xが移動すると、蓋Xの後端部は自重により下降し、図8(II)に示すように、蓋Xの周壁aが下箱Yの周壁bに嵌合し、箱Zが組立てられる。
【0041】
下箱Yに被せられた蓋Xがホッパ30から取り出され、その蓋Xが押え装置60の位置まで搬送されると、蓋Xは複数の押えローラ63で押し下げられる。このため、蓋Xの嵌合が不完全な場合、上記押えローラ63の押圧によって蓋Xは完全な嵌合状態とされる。
【0042】
このように、ホッパ30内の傾斜状態の蓋Xはその下方を搬送される下箱Yの押圧によってホッパ30内から押し出され、そのホッパ30から取り出されると自重により下降して下箱Yに嵌合するため、箱Zをきわめて能率よく組立てることができる。
【0043】
実施の形態で示すように、ホッパ30の下方に一対の板ばね50を設け、この板ばね50によって下箱Yと蓋Xとを相対的に幅方向に位置決めすることにより、下箱Yに蓋Xを確実に被せることができる。
【0044】
【発明の効果】
以上のように、この発明においては、蓋成形用フォーマから排出される蓋をホッパに向けて搬送する途中において上下を反転し、周壁を下向きとして下方に開口した状態でホッパに供給して傾斜状に支持し、一方、下箱成形用フォーマから排出される下箱をホッパの下方に向けて搬送し、その下箱の前壁外面がホッパ内の蓋の前壁内面を押圧する作用によりホッパから蓋を取り出すようにしたので、下箱に蓋を自動的に被せることができ、箱をきわめて能率よく組立てることができると共に、周壁が単壁構造の下箱に対しても蓋を確実に被せることができる。
