Description

本発明は洗剤用紙箱等の箱組立機に用いるのに適した加圧具に関する。更に、その加圧具を組み込んだ箱組立機に関する。   The present invention relates to a pressurizing tool suitable for use in a box assembly machine such as a detergent paper box. Furthermore, it is related with the box assembly machine incorporating the pressurization tool.

洗剤用紙箱等の箱組立機として、特許文献１に記載の如く、箱胴の一端に設けた複数枚の底フラップの接着部を糊剤の介在下で重ね合せ、加圧具により加圧接着するものがある。
特開平8-295317 As a box assembly machine for detergent paper boxes and the like, as described in Patent Document 1, a plurality of bottom flap adhesive portions provided at one end of the box cylinder are overlapped under the presence of a glue and pressure bonded with a pressure tool. There is something to do.
JP-A-8-295317

特許文献１の箱組立機では、複数枚の底フラップの接着部を加圧接着する加圧具を、該底フラップに当接して弾性変形する弾性体エンドレスベルトにて構成している。ところが、箱の底を構成する各部では、底フラップの重なり枚数が１枚でないし、底フラップが１枚だけで構成されていて重なりがない部分もあり、各部の表面は面一でなく凹凸があり、各部の厚みも一様でない。このため、弾性体エンドレスベルトを底フラップに単に当接しても、底フラップの接着部の範囲内にある各部の表面の凹凸、各部の厚みの差に応じて、弾性体エンドレスベルトをそれら各部にくまなく一定の加圧力で当接させることに多大な困難がある。   In the box assembling machine of Patent Document 1, a pressurizing tool that pressurizes and bonds the adhesive portions of a plurality of bottom flaps is configured by an elastic endless belt that abuts against the bottom flaps and elastically deforms. However, in each part constituting the bottom of the box, the number of overlapping bottom flaps is not one, and there is a part where there is only one bottom flap and there is no overlapping, and the surface of each part is not flush and uneven. Yes, the thickness of each part is not uniform. For this reason, even if the elastic endless belt is simply brought into contact with the bottom flap, the elastic endless belt is attached to each part according to the unevenness of the surface of each part within the range of the adhesive part of the bottom flap and the difference in thickness of each part. There is a great difficulty in making contact with a constant pressure throughout.

尚、加圧具として、底フラップの接着部の各部に当接する２枚以上の加圧板を用い、各加圧板の板厚を、底フラップの接着部の範囲内にある各部の表面の凹凸、各部の厚みの差に応ずる板厚に調整することも考えられる。しかしながら、箱品種変更時に、各加圧板の板厚を底フラップの接着部の範囲内にある各部の表面の凹凸等に適合する板厚に調整したり、各加圧位置の位置をそれらの凹凸等に対して正確に位置合せする煩雑な作業が必要になり、型替え時間が長時間になる。   In addition, as a pressurizing tool, using two or more pressure plates abutting on each part of the adhesive part of the bottom flap, the thickness of each pressure plate is made uneven in the surface of each part within the range of the adhesive part of the bottom flap, It is also conceivable to adjust the plate thickness according to the difference in thickness of each part. However, when changing the box type, the thickness of each pressure plate is adjusted to a thickness that matches the unevenness of the surface of each part within the bonded area of the bottom flap, and the position of each pressure position is adjusted to the unevenness. Therefore, a complicated operation for accurately aligning the position and the like is required, and the mold change time becomes long.

本発明の課題は、箱組立機において、複数枚の底フラップの接着部の範囲内にある各点に簡易に、くまなく一定の加圧力を付与可能にすることにある。   SUMMARY OF THE INVENTION An object of the present invention is to make it possible to easily apply a constant pressure all over a point in a box assembling machine within a range of an adhesive portion of a plurality of bottom flaps.

When the side surface (the downward surface in FIG. 2) passes directly above the glue roller 14A, an adhesive is applied to the outer surfaces of the bottom flaps 3A, 3B, 3C, and 3D. The outer flap folding device 14C is formed by punching the bottom flaps 3C and 3D which are the outer flaps of the box 1 held by the carton bucket 24 of the carton conveying device 13 on the downstream side of the pasting roller 14A. As a result, the above-mentioned glued surfaces of the bottom flaps 3C, 3D are overlapped with the above-mentioned glued surfaces of the bottom flaps 3A, 3B.

加圧装置１５はカートン搬送装置１３の搬送チェーン２３上で一定間隔を介する複数位置に加圧具３０を備える。各加圧具３０は前述の各カートンバケット２４に上下で対をなすように、各カートンバケット２４の上方に配置され、各カートンバケット２４とともに同期して移動する。   The pressurizing device 15 includes pressurizing tools 30 at a plurality of positions on the transport chain 23 of the carton transport device 13 through a predetermined interval. Each pressurizing tool 30 is disposed above each carton bucket 24 so as to make a pair with each carton bucket 24 described above, and moves in synchronization with each carton bucket 24.

加圧具３０は搬送チェーン２３に支持されている不図示の昇降装置に支持され、上昇原位置から下降したとき、カートンバケット２４に把持されている箱１の箱胴２の中に挿入され（図３）、加熱装置１６の後述する加熱板４１との間で箱１の前述した如くに糊付けされて重ね合せ状態にある４枚の底フラップ３Ａ〜３Ｄの接着部を加圧し接着する。   The pressurizing tool 30 is supported by an elevating device (not shown) supported by the transport chain 23 and is inserted into the box body 2 of the box 1 held by the carton bucket 24 when the pressurizing tool 30 is lowered from the raised original position ( 3), the adhesive portions of the four bottom flaps 3A to 3D which are glued as described above of the box 1 and overlapped with the heating plate 41 described later of the heating device 16 are pressed and bonded.

加圧具３０は、図３、図４に示す如く、不図示の昇降装置に支持されて昇降せしめられる加圧フレーム３１に複数の加圧ピン３２を並列的に支持し、各加圧ピン３２のそれぞれに設けた弾発体たるコイルばね３３により当該加圧ピン３２を加圧フレーム３１から突出する方向に弾発的に支持する。加圧フレーム３１は、上ベース板３１Ａと下ベース板３１Ｂを連結金具３１Ｃにより上下に連結し、それらベース板３１Ａ、３１Ｂに設けた複数の上下同軸孔３４Ａ、３４Ｂに各加圧ピン３２の上部ピン３２Ａと下部ピン３２Ｂを上下摺動可能に挿通する。加圧ピン３２は上部ピン３２Ａと下部ピン３２Ｂの中間にフランジ状ストッパ３２Ｃを備え、上ベース板３１Ａの下面とストッパ３２Ｃとの間の上部ピン３２Ａまわりにコイルばね３３を設け、コイルばね３３の弾発力でストッパ３２Ｃが下ベース板３１Ｂの上面に当たる突出限まで加圧ピン３２を下ベース板３１Ｂから突出する方向に弾発的に支持する。加圧ピン３２は下部ピン３２Ｂの先端加圧面３２Ｄを球面としている。但し、加圧面３２Ｄは平面等であっても良い。   As shown in FIGS. 3 and 4, the pressurizing tool 30 supports a plurality of pressurizing pins 32 in parallel on a pressurizing frame 31 supported by an elevating device (not shown) and lifted and lowered. The pressure pin 32 is elastically supported in a direction protruding from the pressure frame 31 by a coil spring 33 which is a bullet body provided in each of the above. In the pressure frame 31, an upper base plate 31A and a lower base plate 31B are vertically connected by a connecting bracket 31C, and the upper portions of the pressure pins 32 are inserted into a plurality of upper and lower coaxial holes 34A and 34B provided in the base plates 31A and 31B.

At this time, the heating device 16 applies the four bottom flaps 3 </ b> A to 3 </ b> D that are glued as described above of the box 1 held by the carton bucket 24 of the carton conveying device 13 to the heating plate 41. And the adhesive portions of the bottom flaps 3A to 3D are heated and bonded. Each point of these adhesion portions is connected to the heating plate 41 by the pressure pins 32 of the pressure tool 30 inserted into the box body 2 of the box 1 and placed on the adhesion portions of the bottom flaps 3A to 3D. Squeeze. That is, the heating device 16 heats and bonds the bonded portion to the adhesive solidification in the process in which the pressure tool 30 of the pressure device 15 press-bonds the bonded portions of the bottom flaps 3A to 3D.

箱組立機１０による箱１の製作手順は以下の如くになる。
(1)折りたたみ状態の箱１をカートンマガジン１１からカートン予備折り機１２に供給し、カートン予備折り機１２で四角筒状に折り起こされた箱１をカートン搬送装置１３のいずれかのカートンバケット２４に供給して把持させる。 The manufacturing procedure of the box 1 by the box assembling machine 10 is as follows.
(1) The folded box 1 is supplied from the carton magazine 11 to the carton preliminary folding machine 12, and the carton bucket 24 of any one of the carton transport devices 13 is used to fold the box 1 folded into a square cylinder shape by the carton preliminary folding machine 12. To be gripped.

(2)カートン搬送装置１３のカートンバケット２４に把持した箱１を内フラップ折り込み装置１４Ｂ経由で糊付ローラ１４Ａに通し、内フラップ折り込み装置１４Ｂにより内向き位置に折り込まれた箱１の内フラップたる底フラップ３Ａ、３Ｂの外側面と、外向きに拡開されている底フラップ３Ｃ、３Ｄの外側面に糊付けする。   (2) The box 1 gripped by the carton bucket 24 of the carton transport device 13 is passed through the inner flap folding device 14B through the gluing roller 14A, and the inner flap of the box 1 folded inward by the inner flap folding device 14B. Gluing is performed on the outer surfaces of the bottom flaps 3A and 3B and the outer surfaces of the bottom flaps 3C and 3D that are spread outward.

(3)カートン搬送装置１３のカートンバケット２４に把持している箱１の外フラップたる底フラップ３Ｃ、３Ｄを外フラップ折り込み装置１４Ｃにより内向き位置に折り込み、底フラップ３Ｃ、３Ｄの糊付面を底フラップ３Ａ、３Ｂの糊付面に重ね合せる。   (3) The bottom flaps 3C and 3D, which are the outer flaps of the box 1 held by the carton bucket 24 of the carton conveying device 13, are folded inward by the outer flap folding device 14C, and the glued surfaces of the bottom flaps 3C and 3D are attached. Overlay the glued surfaces of the bottom flaps 3A, 3B.

(4)カートン搬送装置１３のカートンバケット２４に把持されている箱１の箱胴２内に加圧装置１５の加圧具３０を挿入し、各加圧ピン３２により底フラップ３Ａ〜３Ｄの重ね合せ状態にある接着部の各点４のそれぞれを加圧する。   (4) The pressurizing tool 30 of the pressurizing device 15 is inserted into the box body 2 of the box 1 held by the carton bucket 24 of the carton conveying device 13, and the bottom flaps 3A to 3D are overlapped by the pressurizing pins 32. Each point 4 of the bonded portion in the aligned state is pressurized.

(5)カートン搬送装置１３により搬送されて加熱装置１６の加熱板４１上を通過する底フラップ３Ａ〜３Ｄの接着部を加熱する。このとき、上述(4)の加圧具３０の各加圧ピン３２により、底フラップ３Ａ〜３Ｄの接着部の各点４を加熱板４１に対し挟圧し、該接着部を加圧接着固化せしめる。   (5) Heat the bonded portions of the bottom flaps 3 </ b> A to 3 </ b> D that are transported by the carton transport device 13 and pass over the heating plate 41 of the heating device 16. At this time, each point 4 of the bonded portion of the bottom flaps 3A to 3D is pressed against the heating plate 41 by the pressure pins 32 of the pressure tool 30 described in (4) above, and the bonded portion is pressed and solidified. .

(6)カートン搬送装置１３のカートンバケット２４から箱１を解放し、箱１を後続する内容物充填ライン等に向けて払い出す。   (6) The box 1 is released from the carton bucket 24 of the carton conveying device 13, and the box 1 is discharged toward the subsequent content filling line or the like.

本実施例によれば以下の作用効果を奏する。
(a)箱組立機１０において、箱１の複数枚の底フラップ３Ａ〜３Ｄの接着部を加圧接着する過程で、加熱を用いて該接着部を加熱固化するようにしたから、加熱接着時間を短時間にし、生産性を向上できる。 According to the present embodiment, the following operational effects can be obtained.
(a) In the box assembling machine 10, in the process of pressure bonding the bonding portions of the plurality of bottom flaps 3A to 3D of the box 1, the bonding portions are heated and solidified by using heat, so that the heat bonding time Can improve productivity.

箱組立機１０の箱払い出し速度を、箱組立機１０に後続する箱１への内容物充填ライン速度に適合させるように高速化するに際し、箱組立機１０における加熱装置１６の設置ゾーンを長尺化して必要な加熱接着時間を確保する必要の如くがなく、箱組立機１０のライン長を小型にできる。箱組立機１０のライン長を小型にできるから、箱１を保持して搬送するカートンバケット２４や、箱１の底フラップ３Ａ〜３Ｄを加圧する加圧具３０等の設備個数、換言すれば箱品種変更時の型替え交換部品点数は少数で足り、型替え時間も短時間になる。   When the box delivery speed of the box assembly machine 10 is increased so as to match the content filling line speed of the box 1 subsequent to the box assembly machine 10, the installation zone of the heating device 16 in the box assembly machine 10 is elongated. The line length of the box assembly machine 10 can be reduced in size because there is no need to secure the necessary heat bonding time. Since the line length of the box assembling machine 10 can be reduced, the number of equipment such as the carton bucket 24 that holds and transports the box 1 and the pressurizing tool 30 that pressurizes the bottom flaps 3A to 3D of the box 1, in other words, the box The number of replacement parts for changing models is small, and the time required for changing molds is short.

(b)複数枚の重ね合せ状態にある底フラップ３Ａ〜３Ｄを加熱装置１６の加熱板４１の上に載せ、それら底フラップ３Ａ〜３Ｄの上に載る加圧具３０によりそれら底フラップ３Ａ〜３Ｄの接着部を加熱板４１に対し挟圧することにより、底フラップ３Ａ〜３Ｄの接着部を確実に加熱し、加圧接着効率を向上できる。   (b) A plurality of bottom flaps 3A to 3D in a superposed state are placed on the heating plate 41 of the heating device 16, and the bottom flaps 3A to 3D are applied by the pressurizing tool 30 placed on the bottom flaps 3A to 3D. By sandwiching the adhesive portion against the heating plate 41, the adhesive portions of the bottom flaps 3A to 3D can be reliably heated, and the pressure adhesion efficiency can be improved.

また、本発明によれば以下の作用効果を奏する。
(a)箱組立機１０において、加圧具３０が複数の互いに独立的に作動する加圧ピン３２により、底フラップ３Ａ〜３Ｄの接着部の各点４のそれぞれを加圧可能にした。従って、底フラップ３Ａ〜３Ｄの接着部の範囲内にある各点４の表面の凹凸、各点４の厚みの差があっても、それら各点４のそれぞれに対応する加圧ピン３２が他の加圧ピン３２とは独立的に各点４のそれぞれをくまなく一定の加圧力で加圧する。 Moreover, according to this invention, there exist the following effects.
(a) In the box assembling machine 10, each of the points 4 of the bonded portions of the bottom flaps 3 </ b> A to 3 </ b> D can be pressurized by a plurality of pressurizing pins 32 in which the pressurizing tool 30 operates independently of each other. Therefore, even if there is unevenness on the surface of each point 4 within the range of the adhesive portions of the bottom flaps 3A to 3D and there is a difference in the thickness of each point 4, there are other pressure pins 32 corresponding to each of those points 4. Independently of the pressure pin 32, each point 4 is pressurized with a constant pressure throughout.

箱品種変更時にも、各加圧ピン３２は何ら調整を必要とすることなく、底フラップ３Ａ〜３Ｄの接着部の範囲内にある各点４のそれぞれをくまなく一体の加圧力で加圧でき、型替え時間は短時間で足りる。   Even when the box type is changed, each of the pressure pins 32 can be pressurized with an integrated pressure all over each point 4 within the bonded area of the bottom flaps 3A to 3D without any adjustment. The mold change time is short.
