Abstract
Description
しかも、上記の一対の賦形ロールは、ロール軸心が互いに平行な姿勢から僅かでも斜めに偏倚すると、賦形ロールの一端側と他端側とでロール間の隙間や凹凸形状の噛み合い深さ、押圧力等が異なることとなり、シート材に形成される立体形状が不均一となる問題がある。このため、上記のロール間隔等は精緻に調整しなければならず、その操作が極めて煩雑であった。
さらに、シート材に形成された立体形状が上記の下流側賦形ロールに形成された凹凸形状に確りと嵌まり込んでいると、次工程へシート材を送り出す位置で下流側賦形ロールのロール表面からシート材を分離させることが容易でなく、次工程への送り出しに支障をきたす虞や、シート材がこの下流側賦形ロールに巻きついてしまう虞がある。
このため従来の賦形装置では、立体形状の賦形速度を充分に高めることが容易でない問題があった。
即ち本発明1はシート材賦形装置に関し、互いに平行に配置された少なくとも一対の賦形ロール(3・4)を備え、その賦形ロール(3・4)は対面位置で互いに噛み合う凹凸形状(6)をロール周面にそれぞれ備え、両賦形ロール(3・4)間を通過させることでシート材(12)に所定の立体形状を形成する賦形装置であって、上記の賦形ロール(3・4)は、少なくとも一方の賦形ロール(3・4)の回転軸(24)が、軸心違い継手(25)を介して回転駆動手段(10)に連動連結してあることを特徴とする。
また上記の第2設定範囲では、ロール周面が通気孔と通気路と送気口とを順に介して送気手段に連通連結されることから、このロール周面に沿って搬送されるシート材は、送気手段からの送気によりロール周面から離れるように押圧される。
(1)本発明1では、賦形ロールを変位させた場合にその変位を軸心違い継手で吸収することができ、回転駆動手段の賦形ロールへの出力軸を所定位置に位置決めすることができる。この結果、賦形ロールの位置調整が容易であり、ロール間の寸法や噛み合い深さ、押圧力などを容易に調整できるので、シート材に形成する多数の細かな立体形状を、容易にムラなく形成することができる。
図1は本発明の実施形態の賦形装置(2)を用いた、複合シート製造装置(1)の概略構成を示しており、第1供給部(11)から供給された第1シート材(12)と、第2供給部(13)から供給された第2シート材(14)とが、この賦形装置(2)で接合されて複合シート(15)にされる。
上記の賦形ロール(3・4)は第1対面部(C1)で互いに対面し、下側の賦形ロール(4)と上記の押圧ロール(5)とは第2対面部(C2)で対面している。上記の第1シート材(12)は、この第1対面部(C1)に供給されて、下側、即ち搬送方向下流側の賦形ロール(4)により、ロール周面の略半周に沿って上記の第2対面部(C2)へ搬送される。一方、上記の第2シート材(14)はこの第2対面部(C2)に供給されて、下流側賦形ロール(4)と上記の押圧ロール(5)とで上記の第1シート材(12)とともに挟圧され、これにより所定部位が接合されて複合シート(15)にされる。そしてこの複合シート(15)は下流側賦形ロール(4)や押圧ロール(5)から分離され、この賦形装置(2)から次工程へ送り出される。
上下方向中央の、下流側賦形ロール(4)を支持する軸受部(7b)は、所定位置に調整されて固定してある。これに対し上側の賦形ロール(3)と押圧ロール(5)の各軸受部(7a・7c)は、躯体(8)の上部と下部に配置したエアシリンダ(26)により、それぞれ上下方向へ、即ちロール軸心(27)と直交する方向へ進退可能に位置決めして支持してある。
図4と図5に示すように、上記の伝動装置(9)は各ロール(3・4・5)への出力軸(19)を備えている。この出力軸(19)のうち上記の押圧ロール(5)への出力軸(19c)には入力プーリ(20)が付設してあり、この入力プーリ(20)に図外の駆動源がタイミングベルト(21)を介して連動連結してある。一方、上記の各出力軸(19)の一端部にはタイミングプーリ(22)が付設してある。そしてこれらのタイミングプーリ(22)に第2のタイミングベルト(23)が循環させてあり、これにより各出力軸(19)は同期回転するように、互いに連動連結されている。
上記の上側賦形ロール(3)は、第1シート材(12)の厚さが変動すると上記のエアシリンダ(26)の押圧力に抗して上下方向へ僅かに変位するが、この上側賦形ロール(3)の回転軸(24a)と伝動装置(9)の出力軸(19a)とが、上記のシュミット継手(25a)を介して連動連結してあるので、上側賦形ロール(3)は、姿勢を傾けることなく水平姿勢に保持されて平行に変位する。この結果、両賦形ロール(3・4)間は、一端から他端まで均等な間隙に保持され、上記の凹凸形状(6)の噛み合いにより均一な立体形状(18)が形成される。
図7に示すように、この連通部材(30)は、周方向のうち、前記の第1対面部(C1)と第2対面部(C2)との間に対応する第1設定範囲(A)に、上記の通気路(28)と連通可能な吸気口(31)を備えており、第2対面部(C2)よりもシート材進行方向下流側の範囲に対応する第2設定範囲(B)に、上記の通気路(28)と連通可能な送気口(32)を備えている。上記の吸気口(31)は、吸気路(33)を介して図外の吸気手段に連通連結してあり、上記の送気口(32)は、送気路(34)を介して図外の送気手段に連通連結してある。
