〔産業上の利用分野〕
本発明は積層シート押え装置、特に積層されたビニール
や布地等のシート押え装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a laminated sheet pressing device, and particularly to a sheet pressing device for laminated vinyl, fabric, or the like.
従来、積層シート押え装置としては第５図に示すように
積層シート１を載置した積層台２の下面と機枠３間に圧
縮スプリング４を介挿して常時積層台２を上方に押し上
げると共に、積層シート１の上面を爪杆５の爪６によっ
て下方に押圧するようにしたもの、又は第６図に示すよ
うに基部を機枠３に回動自在に枢支した爪杆５の爪６を
積層シート１の上面にシートを一枚一枚搬送する度毎に
係合し、その他のときは爪６を積層シート１の上面から
離脱せしめるようにしたものが知られている。Conventionally, as shown in FIG. 5, a laminated sheet holding device has a compression spring 4 inserted between the lower surface of a laminating table 2 on which a laminated sheet 1 is placed and a machine frame 3 to constantly push the laminating table 2 upward. The upper surface of the laminated sheet 1 is pressed downward by the pawl 6 of the pawl rod 5, or the pawl 6 of the pawl rod 5 whose base is rotatably supported on the machine frame 3 as shown in FIG. A device is known in which the claws 6 are engaged with the upper surface of the laminated sheet 1 each time the sheets are conveyed one by one, and are released from the upper surface of the laminated sheet 1 at other times.
然しなから第５図に示すような積層シート押え装置にお

して弱いスープリングを用いたとしても分割巻き込みが
難しく、又押し上げスプリングの強さが積層シートの高
さ変化により異なるようになって安定したシートの分離
移送が出来ない等の欠点がある。However, in the laminated sheet pressing device shown in Fig. 5, the upper surface of the laminated sheet is constantly pressed by the claws, so if the sheet is cloth, for example, the topmost piece of cloth is rolled into the rotating winding roller. When the fabric is gripped and raised by a presser plate and separated and moved one by one, the friction between the fabrics increases, making it difficult to separate the fabrics even if a weak spring is used as the spring, and the strength of the push-up spring increases. There are drawbacks such as the fact that the height of the laminated sheets varies depending on changes in the height of the laminated sheets, making it impossible to stably separate and transport the sheets.
又第６図に示すような積層シート押え装置においてはシ
ートの把持動作に連動して動作される爪の掛は外し制御
機構が必要であり構成が複雑となる欠点がある。In addition, the laminated sheet holding device shown in FIG. 6 has the disadvantage that a mechanism for controlling the release of the claws, which are operated in conjunction with the sheet gripping operation, is required, resulting in a complicated structure.
本発明は上記のような欠点を除くようにしたものである
。The present invention is intended to eliminate the above-mentioned drawbacks.
（課題を解決するための手段〕
本発明の積層シート押え装置はシート押え爪と、このシ
ート押え爪をその自重によって降下し積層シートの最上
面に対接されるようガイドするガイド機構とより成るこ
とを特徴とする。(Means for Solving the Problems) The laminated sheet pressing device of the present invention includes a sheet pressing claw and a guide mechanism that guides the sheet pressing claw so that it is lowered by its own weight and comes into contact with the uppermost surface of the laminated sheet. It is characterized by
本発明の積層シート押え装置によればシートが一枚一枚
正しく分離され送給されるようになる。According to the laminated sheet pressing device of the present invention, each sheet can be separated and fed correctly one by one.
以下図面によって本発明の詳細な説明する。 The present invention will be explained in detail below with reference to the drawings.
本発明においては第１図に示すように積層台２上の例え

みローラ１０とシート押え板１）を上下動自在に配置せ
しめる。In the present invention, as shown in FIG. 1, sheet presser legs 7 are vertically provided at, for example, the four corners of the stacking table 2, and vertical slits 8 are formed in the sheet presser legs 7 extending downward from the top. A sheet presser claw 9 is provided in the slit 8 of the sheet presser leg 7 so that it moves downward by its own weight using the slit 8 as a guide and is engaged with the upper surface of the laminated sheet 1, and as shown in FIG. A winding roller 10 and a sheet pressing plate 1) are arranged vertically movably on the uppermost surface of the laminated sheet 1, facing each other with a gap greater than the thickness of each sheet.
尚１２は積層台２上の設けた積層シート案内板を示す。Note that 12 indicates a laminated sheet guide plate provided on the laminating table 2.
本発明の積層シート押え装置は上記のような構成である

１０の上方に突出し、この状態で巻き込みローラ１０と
シート押えｖｉｌｌを持ち上げれば積層シート１の最上
部の一枚がこれによって持ち上げられ運ばれるようにな
る。Since the laminated sheet pressing device of the present invention has the above-described configuration, as shown in FIG. Then, as shown in FIG. This allows the sheets to be lifted and carried.
このとき２枚目のシートは１枚目のシートとの付着力に
よって共に持ち上げられるようになるが残りの積層シー
トがその四隅において自重により降下するシート押え爪
９によって押えられるので第４図においてシートの先端
が右方につれるのが阻止され、従って最上部から二枚口
のシートが最上部の一枚のシートに付着して共に送り出
されるのが防止される。At this time, the second sheet is lifted together with the first sheet due to its adhesive force, but the remaining laminated sheets are held down at the four corners by the sheet presser claws 9 that descend due to their own weight, so the sheet is shown in FIG. This prevents the leading edge of the sheet from shifting to the right, thereby preventing two sheets from the top from adhering to the top sheet and being fed together.
上記のように本発明の積層シート押え装置によればシー

究めて簡単となる。As described above, according to the laminated sheet presser of the present invention, the force of the sheet presser pawl 9 to press the top surface of the laminated sheet is due to the sheet presser pawl's own weight, and can be made lighter and more adjustable than when using a spring or the like. This can be easily achieved by adding weights, etc., and unlike those that use springs, the pressing force remains constant even if the height of the top surface of the laminated sheet changes, and the sheet presser claws are linked to the sheet gripping operation. There is no need to manually operate the system, and the configuration is extremely simple.
