しかしながら、上記のシート搬送装置では、シートの分離、吸着を速やかに行い、シートの搬送効率を向上することができるものの、搬送時に、連続シートに生じる皺を伸ばして、連続シートを整然と巻き取ることはできなかった。   However, the above sheet conveying apparatus can quickly separate and adsorb the sheet and improve the sheet conveying efficiency, but at the time of conveyance, the wrinkles generated in the continuous sheet are extended and the continuous sheet is wound up in an orderly manner. I couldn't.

本発明は、上記事情に鑑みてなされたものであって、搬送中の連続シートに発生する皺を伸ばしながら、連続シートを巻き取ることが可能な連続シート搬送装置を提供することを目的とする。   The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a continuous sheet conveying apparatus capable of winding a continuous sheet while stretching the wrinkles generated on the continuous sheet being conveyed. .

Since the air in the linear groove flows from one end surface of the suction table toward the side surface and flows out of the suction table, the frictional force generated between the air and the continuous sheet by this air flow More, the continuous sheet is force acts in suction table side direction, it is possible to extend the wrinkles generated in a continuous sheet.

本発明の連続シート搬送装置の最良の形態について説明する。
なお、この形態は、発明の趣旨をより良く理解させるために具体的に説明するものであり、特に指定のない限り、本発明を限定するものではない。 The best mode of the continuous sheet conveying apparatus of the present invention will be described.
This embodiment is specifically described for better understanding of the gist of the invention, and does not limit the present invention unless otherwise specified.

図１は、本発明の連続シート搬送装置の一実施形態を示す概略平面図である。
この実施形態の連続シート搬送装置１０は、連続シートを搬送する搬送手段３０（３０Ａ、３０Ｂ）と、連続シートの搬送路において、搬送手段３０Ａ，３０Ｂの間に配され、連続シートの皺を伸ばすためのしわ伸ばし手段２０とから概略構成されている。 FIG. 1 is a schematic plan view showing an embodiment of the continuous sheet conveying apparatus of the present invention.
The continuous sheet conveying apparatus 10 of this embodiment is arranged between the conveying means 30 (30A, 30B) that conveys the continuous sheet and the conveying means 30A, 30B in the continuous sheet conveying path, and extends the wrinkles of the continuous sheet. And a wrinkle stretching means 20 for the purpose.

搬送手段３０は、ベルト搬送部３１と、回転ロール３２とから概略構成されている。
ベルト搬送部３１としては、連続シートと接することにより、その摩擦によって連続シートを吸着し、搬送することができる材質からなるベルトであれば特に限定されず、また、この連続シート搬送装置１０によって搬送される連続シートよりも幅が大きいものが用いられる。
回転ロール３２は、モータなどの駆動力により所定の回転数にて回転し、連続シートを、しわ伸ばし手段２０の長手方向に沿って搬送するようになっている。 The conveying means 30 is generally composed of a belt conveying unit 31 and a rotating roll 32.
The belt conveying unit 31 is not particularly limited as long as it is made of a material made of a material capable of adsorbing and conveying the continuous sheet by friction by contacting the continuous sheet, and is conveyed by the continuous sheet conveying device 10. A sheet having a width larger than that of the continuous sheet is used.
The rotating roll 32 is rotated at a predetermined rotational speed by a driving force such as a motor, and conveys the continuous sheet along the longitudinal direction of the wrinkle-stretching means 20.

しわ伸ばし手段２０は、連続シートを吸着する吸着テーブル２１を有している。
吸着テーブル２１の吸着面２１ａ側には、吸着テーブル２１の長手方向の一方の端面２１ｂを基端とし、緩やかに湾曲しながら吸着テーブル２１の側面２１ｃまたは側面２１ｄに達する線条溝２２，２２，・・・が多数並列に設けられている。言い換えれば、線条溝２２は、前記の端面２１ｂを基端として吸着テーブル２１の長手方向に進みながら、前記の側面２１ｃまたは側面２１ｄに向かって緩やかに湾曲し、最終的に前記の側面２１ｃまたは側面２１ｄに達している。
また、多数の線条溝２２は、吸着テーブル２１の長手方向に沿う中心線を境にして、ほぼ対象に設けられている。 The wrinkle stretching means 20 has a suction table 21 that sucks continuous sheets.
On the suction surface 21a side of the suction table 21, the linear groove 22, 22, which reaches the side surface 21c or the side surface 21d of the suction table 21 while gently curving, with one end surface 21b in the longitudinal direction of the suction table 21 as the base end. Are provided in parallel. In other words, the linear groove 22 gradually curves toward the side surface 21c or the side surface 21d while proceeding in the longitudinal direction of the suction table 21 with the end surface 21b as the base end, and finally the side surface 21c or It has reached the side surface 21d.
In addition, a large number of linear grooves 22 are provided substantially on the subject with a center line along the longitudinal direction of the suction table 21 as a boundary.

この線条溝２２は、その長手方向と垂直な断面の形状が凹状をなしており、吸着テーブル２１を貫通していない。
また、この線条溝２２は、吸着テーブル２１の長手方向の一方の端面２１ｂにおいては、閉口している。すなわち、線条溝２２は、その基端となる端面２１ｂにおいて、開口していない。
一方、この線条溝２２は、吸着テーブル２１の側面２１ｃまたは側面２１ｄにおいては、開口している。 The linear groove 22 has a concave cross-sectional shape perpendicular to the longitudinal direction, and does not penetrate the suction table 21.
The linear groove 22 is closed on one end face 21 b in the longitudinal direction of the suction table 21. That is, the linear groove 22 is not open in the end surface 21b which becomes the base end.
On the other hand, the linear groove 22 is open on the side surface 21 c or the side surface 21 d of the suction table 21.

また、吸着テーブル２１の吸着面２１ａ側には、線条溝２２が設けられていない領域のほぼ全ての領域に、連続シートを吸引固定するための吸引孔２３が規則的または不規則的に多数設けられている。
吸引孔２３は、平面形状が円形状をなしており、かつ、吸着テーブル２１の厚みの方向の断面形状が円柱状をなしている。
さらに、吸着テーブル２１は、その内部が空間領域（図示略）をなしており、吸引孔２３がこの空間領域と連通している。これにより、真空ポンプなどからなる吸引手段（図示略）を用いて、前記の空間領域内の空気を吸引することによって、吸着テーブル２１に連続シートが吸着される。 Further, on the suction surface 21 a side of the suction table 21, there are a large number of regular or irregular suction holes 23 for sucking and fixing the continuous sheet in almost all areas where the linear grooves 22 are not provided. Is provided.
The suction hole 23 has a circular planar shape, and a cross-sectional shape in the thickness direction of the suction table 21 has a cylindrical shape.
Further, the inside of the suction table 21 forms a space area (not shown), and the suction hole 23 communicates with the space area. As a result, the continuous sheet is adsorbed on the adsorption table 21 by aspirating air in the space area using a suction means (not shown) including a vacuum pump.

吸着テーブル２１の長さは特に限定されないが、連続シート５０の材質や厚みなどに応じて適宜調整される。
また、吸着テーブル２１の幅は、連続シート５０よりも大きくなっている。 The length of the suction table 21 is not particularly limited, but is appropriately adjusted according to the material and thickness of the continuous sheet 50.
Further, the width of the suction table 21 is larger than that of the continuous sheet 50.

次に、図２を参照して、この実施形態の連続シート搬送装置１０を用いた連続シートの搬送方法を説明する。
まず、連続シート５０を、その搬送方向の先端部側から搬送手段３０Ａのベルト搬送部３１、しわ伸ばし手段２０の吸着テーブル２１、および、搬送手段３０Ｂのベルト搬送部３１上に配する。この時、連続シート５０の先端部側を、ガイド４１，４１により吸着テーブル２１およびベルト搬送部３１に対して支持しておく。 Next, a continuous sheet conveying method using the continuous sheet conveying apparatus 10 of this embodiment will be described with reference to FIG.
First, the continuous sheet 50 is arranged on the belt conveyance unit 31 of the conveyance unit 30A, the suction table 21 of the wrinkle stretching unit 20, and the belt conveyance unit 31 of the conveyance unit 30B from the leading end side in the conveyance direction. At this time, the leading end side of the continuous sheet 50 is supported by the guides 41 and 41 with respect to the suction table 21 and the belt conveyance unit 31.

この状態で吸引孔２３を介して吸引手段により、前記の空間領域内の空気を吸引することによって連続シート５０を吸着テーブル２１の吸着面２１ａに吸着させるとともに、回転ロール３２により、ベルト搬送部３１を回転させて、連続シート５０を吸着テーブル２１の長手方向（図２の大きな矢印方向）に搬送する。
この時、連続シート５０の移動（搬送）に伴って、線条溝２２内の空気が、吸着テーブル２１の一方の端面２１ｂから、側面２１ｃおよび側面２１ｄに向かって流れ、吸着テーブル２１外に流出する（図２の小さな矢印方向）。この空気の流れによって空気と連続シート５０との間に生じる摩擦力により、連続シート５０には、吸着テーブル２１の他方の端面２１ｅ側にいくにしたがって大きくなる力が、吸着テーブル２１の側面２１ｃおよび側面２１ｄ方向、すなわち、連続シート５０の搬送方向とは垂直な方向に作用する。これにより、連続シート５０に発生した皺を伸ばすことができる。 In this state, the continuous sheet 50 is sucked to the suction surface 21a of the suction table 21 by sucking the air in the space area by the suction means through the suction hole 23, and the belt conveyance unit 31 is rotated by the rotary roll 32. And the continuous sheet 50 is conveyed in the longitudinal direction of the suction table 21 (in the direction of the large arrow in FIG. 2).
At this time, as the continuous sheet 50 moves (conveys), the air in the linear groove 22 flows from one end surface 21b of the suction table 21 toward the side surface 21c and the side surface 21d and flows out of the suction table 21. (Small arrow direction in FIG. 2). Due to the frictional force generated between the air and the continuous sheet 50 due to the air flow, the continuous sheet 50 has a force that increases toward the other end surface 21e of the suction table 21. The side surface 21d acts in a direction perpendicular to the direction in which the continuous sheet 50 is conveyed. Thereby, the wrinkles generated in the continuous sheet 50 can be extended.

この連続シート５０に対して吸着テーブル２１の側面２１ｃおよび側面２１ｄ方向に作用する力は、搬送中の連続シート５０に対して常に作用し、結果として、連続シート５０を、皺なく、整然と搬送し、巻き取ることができる。   The force acting on the continuous sheet 50 in the direction of the side surface 21c and the side surface 21d of the suction table 21 always acts on the continuous sheet 50 being conveyed. Can be wound up.
