Description

200305386 玖、發明說明: 【啦明所屬之技術領域】 重、%機將眾多工業用的原始滾筒改變為用於浴室紙 張、紙毛巾等產品之小型滾筒。中央型重繞機已被揭示於 美國追加專利28,353中(以下簡稱”353號專利”)。中央型 重繞機是利用轉臺的旋轉而將織物捲繞於輥芯上。 到切及轉移是捲繞滾筒最具關鍵性的運作。織物必須 被剪裁斷以便停止滾筒的捲繞。然後,被剪裁斷的織物主 要端緣必須被轉移至另一新的滾筒。接著,新的滾筒須被 旋轉以便啟始其新的捲繞。當織物在高速狀態下進行移動 時’這些步驟便可被重覆且確實地完成。每個滾筒最好露 出精確的紙張數量,如此織物方可統一地被捲繞。 【先前技術】 在工業用途上,詞語’’基座滾筒,,(bedroll )通常乃指 重繞機中的主要捲繞滾筒。舉例來說,在,,353號專利,,中 的基座滾筒乃是與一剪切滾筒做運用,以便在織物以預定 長度被捲繞在一圓木織物之後將其分紗。基座滾筒以一種 連續的捲繞程序將剪斷後織物的主要端緣移轉至一新的滾 筒。在”3 53號專利”所揭示的裝置中,剪切及移轉機置包 括一系列的針梢、剪切刀刃,以及移轉襯墊,其皆被裝置 在基座滾筒中。當剪切及移轉機置被打開時,針梢將把織 物保持在旋轉的滾筒下,而織物將藉著露出於基座滚筒處 的剪切滾筒刀刃之交互作用被進行剪切。 工業上可取得的中央重繞機可由位於威斯康辛州綠 ’母市的 Paper Converting Machine Company 而購得,其在 5 D:We__/新式屮 心 ρ_·〇778 200305386 Π筒上可包括移動式的針梢以握持剪切織物的主要端 、.豪,並且將該主要端緣運送至預定位置。此外,門 的運用可將針梢保持於一未作 止。一前b 77 罝到織物破剪切為 切刀'切刀刃可被安裝在剪切滾筒處,而基座滾筒的剪 刀刀刀則可移動地安裝於其中。 基座滚同與針梢組成必須 Λ ^ , 員為、准修而做疋期的更換。 ^广作中’該組合的更換或調整最好 精確的裝配尺寸以及肚微的 也〜3 ,人a —的决差。在傳統的設計中,刀刃 ,-且δ匕括在十字柄上必須 、攸氣解的夾鉗以替換 滾筒針梢、襯塾與心轴之間的 ;換件基座 疋,且零件必須以傳統 祈口又 甚A α 4 置進仃更換。頂部基座滾筒的外 盍通吊須被移除以便置入機 ...,^ ώ 成置、、且合。因此,極多數的機械 在更換或重新設定刀刀和針 铖械 + ·、 评%便常發生,,停產,,(down ime )。除此之外,在 .^ 針梢與心軸之間的間隙時亦常存 在一種錯誤風險,其即為 4吊存 M m ^ 貢吩間及困難之問題。 美國專利序號4,28〇,66 μ / - ^ ^下間稱’,6 6 9號專利,,)揭 不-種用於伸張性織物 。寻矛"揭 669號專利中,其示出自動、、哉物重繞機。在第十圖的 卜 ^ 種運用單獨針梢的構造。#•斜梢 每次必須被分隔更換,進均及針柏 H m ^ 在块類政置的預定實施上產生 種几長且困難的維修程序。 度王 本產業上真正需要的是一 設計,以便在毋須影響精確 刀與針梢組合的改良 刀之更換。除此之外,—種、^差下,幫助針梢與刀 最小人力之裳置與方更:針梢和/或刀刃所需求的 .減少停產時間的組合亦為有=的。而在維修運作時能夠
