本発明は、SMC(シートモールデイングコンパウンド
)つまりプリプレグマットの両面に被覆されたフィルム
を剥離する装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for peeling off a film coated on both sides of an SMC (sheet molding compound) or prepreg mat.
SMCシー1〜材(以下単にSMCという)は通常両面
をフィルムで被覆されており、使用に際しては該フィル
ムを剥がす必要がある。SMC sheet 1~ material (hereinafter simply referred to as SMC) is usually coated with a film on both sides, and it is necessary to peel off the film before use.
このフィルムの剥ぎ取りに当っては、従来第2図に概略
図で示すような装置が使用されている。Conventionally, a device as schematically shown in FIG. 2 has been used to peel off this film.
すなわち、SMCIを送りロール13.13’によって
垂下状態に送り出しながら、干一方に設けた引き取りロ
ール14.14’ との間にドロー比をかけた状態で、
両ロールの中間に設けた剥ぎ取りロール15.15’に
よってフィルム2.2′を剥ぎ取り、順次ロール16.
16’に巻き取るように構成されている。That is, while the SMCI is sent out in a hanging state by the feed roll 13.13', a draw ratio is applied between it and the take-up roll 14.14' provided on the drying side.
The film 2.2' is stripped off by a stripping roll 15.15' located between the two rolls, and then rolled 16.
16'.
このような従来の装置においては、送りロール13.1
3′と引き取りロール14.14’との間の緊張状態を
保ち剥ぎ取り易くするために、両ロール間にドローをか
けているが、これがかかりすぎるとSMCが切れる事故
が発生し易い。In such conventional devices, the feed roll 13.1
In order to maintain tension between the rolls 14 and 14' and the take-up rolls 14 and 14', a draw is applied between both rolls, but if this is applied too much, an accident in which the SMC breaks may easily occur.
また実際には引き取り量が一定に保たれにくい。Furthermore, in reality, it is difficult to maintain a constant amount of withdrawals.
すなわちSMCの粘着性の変化で、引き取りロール14
.14’がSMCとの接触でスリップを起すと、引き取

なって、両ロール間においてSMCにたるみが生じ、フ
ィルムが剥離しにくくなったり、SMC本体が送りロー
ルや剥ぎ取りロールに巻き込まれたりする事故が生じ、
剥ぎ取りがスムーズに行われなくなるという問題点があ
った。In other words, due to changes in the adhesiveness of SMC, the take-up roll 14
.. If 14' slips due to contact with the SMC, the amount of take-up will decrease, and the amount of feed by the feed roll will increase, causing slack in the SMC between both rolls, making it difficult to peel off the film, and causing the SMC to slip. Accidents may occur where the main unit gets caught in the feed roll or stripping roll.
There was a problem in that the stripping could not be performed smoothly.
本発明の目的は、このような従来の問題点を解決し、ス
ムーズにフィルムの剥ぎ取りができる装置を提供するに
ある。An object of the present invention is to solve these conventional problems and provide an apparatus that can smoothly peel off the film.
上記の目的を達成するため、本発明のSMCシート材の
被覆フィルム剥ぎ取り装置は、上端部にSMCシート材

うにしたことを特徴とするものである。In order to achieve the above object, the SMC sheet material coating film stripping device of the present invention is provided with feed rolls (3, 3') equipped with a one-way clutch that feeds the SMC sheet material (1) in a suspended manner at the upper end, Below it are a coating film (2, 2') stripping roll (5, 5') of the SMC sheet material (1) and an SMC sheet material take-up roll (4,
4') are sequentially arranged at predetermined intervals, and normally the SMC sheet material (1) is taken up by the rotational movement of the take-up rolls (4, 4'), and the SMC sheet material (1) is
If slip occurs between the MC sheet material (1) and the take-up speed is lower than the set take-up speed, the feed rolls (3, 3')
This is characterized in that the SMC sheet material (1) is fed out by the rotational movement of the SMC sheet material (1).

ール(4,4’)と送りロール(3,3’)とのロール
直径が同じである場合には、引き取りロール(4,4’
)の回転速度を多少早めに設定されている。When peeling off the coating film using the device of the present invention,
In order to pull the SMC between the take-off roll (4, 4') and the feed roll (3, 3') with a built-in one-way clutch and maintain tension, the take-off roll (4, 4') and feed roll (3, 3') are If the roll diameter is the same as that of the roll (3, 3'), the take-up roll (4, 4')
) rotation speed is set somewhat earlier.
上記のように構成されているのて、SMCは送りロール
を通り、下方に垂下し、引き取りロールで引き取られな
がら、その途中で剥ぎ取りロールによりフィルムが剥ぎ
取られる。With the structure described above, the SMC passes through the feed roll, hangs downward, and is taken up by the take-up roll, while the film is peeled off by the peel-off roll along the way.
通常の状態ではSMCシート材は引き取りロールの回転
運動によって引き取られ、またこのSMCシート材に接
触している送りロールもSMCシート材によってフリー
に回転される。Under normal conditions, the SMC sheet material is taken up by the rotational movement of the take-up roll, and the feed roll that is in contact with this SMC sheet material is also freely rotated by the SMC sheet material.
このように剥ぎ取りが進行中に、SMC表面の粘着性等
に変化が生じて引き取りロールがスリップし、SMCの
引き取り速度が低下して設定以下の引き取り速度になる
と、今度は送りロールの回転運動によってSMCを送り
出すので、引き取りロール面のスリップが解消され、再
び元の状態に戻って引き取りロールによりSMCが引き
取られ、引き取り速度も回復する。While stripping is progressing in this way, the take-up roll slips due to changes in the adhesiveness of the SMC surface, and when the SMC take-up speed decreases to below the set take-up speed, the rotational movement of the feed roll changes. Since the SMC is sent out, the slip on the take-up roll surface is eliminated and the SMC is returned to its original state again, and the SMC is taken up by the take-up roll, and the take-up speed is also restored.
したがって、送りロールと引き取りロールの間でSMC
がたるみを起こすことなく定量のSMCが送り出される
と裁断等の次の作業に供される。Therefore, SMC between the feed roll and take-up roll
When a certain amount of SMC is sent out without causing any sagging, it is used for the next operation such as cutting.

MC12,2' is a film coated on both sides.
3.3′はSMCを挟着して下方に垂下させて送り出す
ワンウェイクラッチ内蔵の送りロールであり、図示して
いないが駆動装置により引き取りロールより低い回転速
度で回転される。Reference numeral 3.3' denotes a feed roll with a built-in one-way clutch that pinches the SMC and sends it out by hanging downward, and although it is not shown, it is rotated by a drive device (not shown) at a rotation speed lower than that of the take-up roll.
4.4′は引き取りロールであって、駆動装置により矢
示方向に回転してSMCを引き取る。Reference numeral 4.4' denotes a take-up roll, which is rotated by a drive device in the direction of the arrow to take off the SMC.
該引き取りロール4,4′と前記送りロール3゜3′と
の軸回転速度比は、例えば両者のロール径が同一の場合
には、SMCにドローを与えるため5:4程度に設定す
ることが好ましい。For example, when the diameters of both rolls are the same, the shaft rotational speed ratio of the take-up rolls 4, 4' and the feed roll 3°3' can be set to about 5:4 in order to give a draw to the SMC. preferable.
5.5′は前記両ロール間にSMCの両側に相対して設
けられたフィルム剥ぎ取りロールであって、該剥ぎ取り
ロール5,5′で剥ぎ取られたフィルムは巻き取りロー
ル6,6′に各々巻き取られる。Reference numeral 5.5' denotes a film stripping roll provided between the two rolls facing each other on both sides of the SMC, and the film stripped off by the stripping rolls 5, 5' is transferred to take-up rolls 6, 6'. Each is wound up.
送りロールにワンウェイクラッチ内蔵の送りロールを使

確実に防止でき、また垂下するSMCは常に適正な緊張
状態に保持され、たるみを生ずることがなく、不規則な
巻き込みが防止されるので、スムーズにフィルムの剥ぎ
取りを行うことができる。Since a feed roll with a built-in one-way clutch is used, it is possible to reliably prevent the SMC from breaking due to the draw, and the hanging SMC is always maintained at an appropriate tension state, preventing sagging and preventing malfunctions. Since regular entrainment is prevented, the film can be peeled off smoothly.
