Description

【0001】
【発明の属する技術分野】
本発明は、紙料分配管の間隔調整装置。詳しくは、多数の紙料分配管の間隔調整を同時に正確に行なえる調整装置に関する。
【0002】
【従来の技術】
フローボックスへ原料紙料を配分給送する分配管の間隔調整装置として、シリンダを用いる案は、本件特許出願人の先願に係る特願平10−327602号において開示されている。
【0003】
しかしながら、このものは、設備費が高く付くだけでなく、順次作動式であるため調整に時間が掛かり、且つ、調整寸法にバラツキを生じ易い問題点がある。
【0004】
【発明が解決しようとする課題】
本発明に係る紙料分配管の間隔調整装置は、配置される所要数の分配管の間隔を同時に正確に調整することができる間隔調整装置を提供することを課題としている。
【0005】
【課題を解決するための手段】
前記課題を解決するため、本発明に係る紙料分配管の間隔調整装置は、下記の構成を採用することを特徴とする。
(1) フローボックスへ原料を分配給送する所要数の分配管の間隔を、紙料の分配巾を変化させるために調整する間隔調整装置であって、各分配管は、各々にスライダーを取付けて、このスライダーをフローボックス上に左右の方向に設けられた一対のガイドに移動自在に支持させるとともに、上記一対のガイドの間に、上下方向に移動自在とした操作板を設け、この操作板に分配管を嵌合する長孔を上または下端側が最小間隔で、反対端側が最大間隔となるように分配管と同数個設け、上記操作板には、これを昇降させて各長孔と各分配管との係合位置を変化させる昇降機構を連係させる。
(2) 操作板の昇降機構と、フローボックスにおける可動側枠の移動調整機構とを連動機構により連係させて、分配管の間隔調整とフローボックスの抄紙巾調整とを連動して行なわせる。
【0006】
【発明の実施の形態】
以下に本発明に係る紙料分配管の間隔調整装置の実施の形態を図面に基いて説明する。
【0007】
図面各図は、本発明に係る紙料分配管の間隔調整装置を示す。この間隔調整装置Aは、フローボックス1へ原料紙料を分配給送する所要数の分配管2と、各分配管2に取付けたスライダー3と、これらスライダーを移動自在に支持するガイド4と、間隔が変化する長孔5を並設して、これら長孔5に前記分配管2を嵌合した操作板6と、この操作板6を昇降させる昇降機構7とにより構成される。
【0008】
フローボックス1は、図1、図2に示すように底板1aと、固定の後板1bと、内外に移動自在とした両側板8,8とにより構成して、所要数の分配管2により後側から原料紙料を分配給送し、堰板(図面省略)によりフローボックス1の内部全体へ広がらせると共に、紙料の流速、流態等を調整して図示してないスクリーン上へ側板8,8の間隔で決まる抄紙巾により一様な速さと厚さで紙料を流出させる。
【0009】
フローボックス1の両側板8,8を移動調整するには、図1、図2に示すように底板1aの両側に固定板9,9を設け、これら固定板9,9に一対のウオーム減速機10,10を前後に離隔させて取付け、これらウオーム減速機10,10のウオームホイール11,11にめねじ12,12を内設し、これらめねじ12,12に送りねじ13,13を螺合させて、送りねじ13,13の先端を両側板8,8へ固定する構成を採用する。そして、一対のウオーム減速機10,10のウオーム14,14に、回転ハンドル15の回転を伝動機構16を介して伝達することにより、送りねじ13,13を進退させて、両側板8,8を底板1aと後板1bとの水蜜を保持しながら平行移動させ、両側板8,8の間隔調整を行なうようにする。
【0010】
紙料の分配管2は、逆U字形の側面形状に形成して、中間の水平部をフローボックス1の後板1b上方に位置させ、この部分に図4、図5に示すように離隔する一対のスライダー3,3を取付け、前側の垂下部を図3に示すようにフローボックス1内へ挿入し、後側の垂下部には、供給管(図面省略)から原料紙料を導入するフレキシブルチューブ17を接続する。
【0011】
紙料の分配管2に取付けたスライダー3は、フローボックス1における後板1bの上側に左右の方向に配設した一対の水平ガイド4に係合させて、内設したボール・ローラー(図面省略)等をガイド4と転り接触させることにより、円滑軽快な左右移動が行われるようにする。
【0012】
分配管2の間隔調整操作を行なう操作板6は、上下の方向に配設するもので、板面に分配管2を嵌合する長孔5を、上または下端側が希望する最小間隔になり、反対端側が最大間隔となるように分配管2と同数だけ上下の方向に設ける。そして、この操作板6の両端には、スライダー18を取付けて、このスライダーフ18をフローボックス1の後側に縦枠19に固定して設けた垂直のガイド20に係合させ、操作板6に設けた各長孔5には各分配管2を嵌合して、操作板6を上下に移動させると、長孔5の分配管2が嵌合している部分の間隔が狭まるか、反対に広まるため、各分配管2はこの間隔変化に応じて相互の間隔を同時に正確に調整される。
【0013】
分配管2の長孔5に嵌合する部分には、図5に示すよう筒体21を取付けて、この筒体1に減摩リング22を交換可能に支持させ、該リング22を長孔5の壁面と摩擦させて間隔調整を行ない、この調整操作によって分配管2が摩耗しないようにする。
【0014】
操作板6の昇降機構7は、縦枠19上に図1、図2に示すように渡した梁材23に一対のウオーム減速機24を取付け、これらウオーム減速機24,24のウオームホイール25,25に図4に示すようにめねじ26,26を内設して、これらめねじ26,26に昇降機構の送りねじ7,7を螺合させ、この送りねじ7,7の先端を操作板6に固定する構成を採用する。そして、一対のウオーム減速機24,24のウオーム27,27を、回転ハンドル28の回転をチエン29により伝達して回転させると、送りねじ7,7が進退して、操作板6を所定の範囲内において昇降させるようにしてある。
【0015】
フローボックス1における両側板8,8の間隔調整を行なう回転ハンドル15の軸30と、分配管2の間隔調整を行なう回転ハンドル28の軸31とを、図3に示すようにチエン32により連係させれば、一方の回転ハンドルを回転させると、他方の回転ハンドルも回転して、分配管2の間隔調整とフローボックスの側板8,8の間隔調整とを連動して行なう。
【0016】
前記実施形態に示すものは、フローボックス1の側板8,8の間隔調整及び分配管2の間隔調整を回転ハンドル15または回転ハンドル28の手動回転により行なったが、回転ハンドル15の軸30と回転ハンドル28の軸31の両方に減速機モータ等を連結するか、または、一方の軸に減速機モータを連係させて、両側板8,8の間隔調整と、分配管2の間隔調整とを動力により行なうことができるし、また、前記実施形態においては、移動機構及び昇降機構に送りねじを用いたが、送りねじの代りにピニオン・ラック、シリンダー、その他の往復機構を採用しても同様の作用効果が発揮される。
【0017】

Thus, a configuration in which the tips of the feed screws 13 and 13 are fixed to the side plates 8 and 8 is adopted. Then, by transmitting the rotation of the rotary handle 15 to the worms 14 and 14 of the pair of worm reducers 10 and 10 via the transmission mechanism 16, the feed screws 13 and 13 are advanced and retracted, and the both side plates 8 and 8 are moved. While holding the nectar between the bottom plate 1a and the rear plate 1b, they are moved in parallel to adjust the distance between the side plates 8, 8.
[0010]
The stock distribution pipe 2 is formed in an inverted U-shaped side shape, and an intermediate horizontal portion is positioned above the rear plate 1b of the flow box 1, and is separated from this portion as shown in FIGS. A pair of sliders 3 and 3 are attached, and the front hanging part is inserted into the flow box 1 as shown in FIG. 3, and the raw material is introduced into the rear hanging part from a supply pipe (not shown). Connect the tube 17.
[0011]
A slider 3 attached to the stock distribution pipe 2 is engaged with a pair of horizontal guides 4 disposed in the left and right directions on the upper side of the rear plate 1b in the flow box 1 to provide a ball roller (not shown). ) Or the like is brought into rolling contact with the guide 4 so that smooth and light left and right movement can be performed.
[0012]
The operation plate 6 for adjusting the interval of the distribution pipe 2 is arranged in the vertical direction. The long hole 5 for fitting the distribution pipe 2 to the plate surface has a desired minimum interval on the upper or lower side, As many as the distribution pipes 2 are provided in the vertical direction so that the opposite end side has the maximum distance. Then, sliders 18 are attached to both ends of the operation plate 6, and the slider plate 18 is engaged with a vertical guide 20 provided on the rear side of the flow box 1 and fixed to the vertical frame 19. When the distribution pipes 2 are fitted in the long holes 5 provided in the, and the operation plate 6 is moved up and down, the interval between the portions where the distribution pipes 2 of the long holes 5 are fitted is reduced or opposite. Therefore, the distance between the distribution pipes 2 can be accurately adjusted simultaneously according to the change in the distance.
[0013]
As shown in FIG. 5, a cylindrical body 21 is attached to a portion of the distribution pipe 2 that fits into the long hole 5, and the antifriction ring 22 is supported on the cylindrical body 1 in an exchangeable manner. The distance is adjusted by rubbing against the wall surface of the pipe so that the distribution pipe 2 is not worn by this adjustment operation.
[0014]
The elevating mechanism 7 of the operation plate 6 has a pair of worm speed reducers 24 attached to a beam member 23 passed on a vertical frame 19 as shown in FIGS. 1 and 2, and worm wheels 25 of the worm speed reducers 24, 24, As shown in FIG. 4, female screws 26 and 26 are provided in 25, the feed screws 7 and 7 of the elevating mechanism are screwed into the female screws 26 and 26, and the tips of the feed screws 7 and 7 are connected to the operation plate. The structure fixed to 6 is adopted. When the worms 27, 27 of the pair of worm speed reducers 24, 24 are rotated by transmitting the rotation of the rotary handle 28 by the chain 29, the feed screws 7, 7 are advanced and retracted to move the operation plate 6 in a predetermined range. It is made to raise and lower inside.
[0015]
The shaft 30 of the rotary handle 15 for adjusting the distance between the side plates 8 and 8 in the flow box 1 and the shaft 31 of the rotary handle 28 for adjusting the distance between the distribution pipes 2 are linked by a chain 32 as shown in FIG. Then, when one rotary handle is rotated, the other rotary handle is also rotated, and the interval adjustment of the distribution pipe 2 and the interval adjustment of the side plates 8 and 8 of the flow box are performed in conjunction with each other.
[0016]
In the embodiment, the adjustment of the interval between the side plates 8 and 8 of the flow box 1 and the interval of the distribution pipe 2 are performed by manually rotating the rotary handle 15 or the rotary handle 28. A reduction gear motor or the like is connected to both the shafts 31 of the handle 28 or a reduction gear motor is linked to one of the shafts 28 to adjust the distance between the side plates 8 and 8 and the distance adjustment of the distribution pipe 2. In the above embodiment, a feed screw is used for the moving mechanism and the lifting mechanism. However, a pinion rack, cylinder, or other reciprocating mechanism may be used instead of the feed screw. The effect is demonstrated.
