Abstract

<P>PROBLEM TO BE SOLVED: To obtain a device for stretching screen gauze capable of manufacturing a screen plate by which highly accurate screen printing can be realized by efficiently preventing the occurrence of a strain in a screen at spots close to the four corner parts after uniformly and laterally imparting prescribed tension to the screen. <P>SOLUTION: Prescribed tension can be imparted to a clamped screen after clamping the front/rear and the right/left of the screen by clamping devices at the front, rear, right, and left parts in the device for stretching screen gauze. The device for stretching screen gauze is composed of auxiliary clamping devices at the front/rear parts capable of laterally imparting prescribed tension to the screen by clamping both end parts of the screen in the vicinity of the clamping devices at the front/rear parts when the screen is clamped by the clamping devices at the front/rear parts. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明はスクリーン版を製造する場合に使用するスクリーン紗張装置に関する。   The present invention relates to a screen tensioning device used for producing a screen plate.

従来のスクリーン紗張装置は、スクリーンの前後左右を前後左右部のクランプ装置でクランプして、該クランプされたスクリーンに所定の張力を付与するように構成されている。   A conventional screen tensioning device is configured to clamp a front, back, left, and right of the screen with front and rear, left and right clamping devices and apply a predetermined tension to the clamped screen.

このため、スクリーンの前後左右をクランプした状態で前後左右方向にスクリーンを引張るため、スクリーンの前後部分のクランプ部分には左右方向の引張力が作用しないとともに、左右部分のクランプ部分には前後方向の引張力が作用しないため、枠体に固定されるスクリーンの四隅部寄りの部位に歪みが生じるという欠点があった。
実公平５−１７２４０ For this reason, the screen is pulled in the front / rear / left / right direction with the front / rear / left / right clamped state of the screen, so that the left / right tension is not applied to the front / rear part of the screen and the front / rear direction is not applied to the left / right clamp part. Since the tensile force does not act, there is a drawback that distortion occurs in the portions near the four corners of the screen fixed to the frame.
Reality 5-17240

本発明は以上のような従来の欠点に鑑み、スクリーンを均一に左右方向に所定の張力を付与できるようにして、四隅部寄りの部位のスクリーンに歪みが生じるのを効率よく阻止して、高精度のスクリーン印刷が可能なスクリーン版を製造することができるスクリーン紗張装置を提供することを目的としている。   In view of the above-mentioned conventional drawbacks, the present invention enables the screen to be uniformly applied with a predetermined tension in the left-right direction, and effectively prevents distortion on the screen near the four corners. An object of the present invention is to provide a screen tensioning device capable of producing a screen plate capable of accurate screen printing.

本発明の前記ならびにそのほかの目的と新規な特徴は次の説明を添付図面と照らし合わせて読むと、より完全に明らかになるであろう。
ただし、図面はもっぱら解説のためのものであって、本発明の技術的範囲を限定するものではない。 The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.

上記目的を達成するために、本発明はスクリーンの前後左右を前後左右部のクランプ装置でクランプして、該クランプされたスクリーンに所定の張力を付与することができるスクリーン紗張装置において、前記前後部のクランプ装置でスクリーンをクランプする時に、該前後部のクランプ装置の近傍位置のスクリーンの両端部をクランプして、左右方向に所定の帳力を付与することができる前後部の補助クランプ装置とでスクリーン紗張装置を構成している。   In order to achieve the above object, the present invention relates to a screen tensioning device capable of clamping a front / rear / right / left / right / left / right clamping unit to apply a predetermined tension to the clamped screen. A front and rear auxiliary clamp device that clamps both ends of the screen in the vicinity of the front and rear clamping devices when a screen is clamped by a front clamping device, and can impart a predetermined writing force in the left and right direction; Constitutes a screen tensioning device.

以上の説明から明らかなように、本発明にあっては次に列挙する効果が得られる。   As is clear from the above description, the present invention has the following effects.

（１）前後部のクランプ装置でスクリーンをクランプする時に、該前後部のクランプ装置の近傍位置のスクリーンの両端部をクランプして、左右方向に所定の張力を付与することができる前後部の補助クランプ装置を設けているので、前後部のクランプ装置でクランプするスクリーンの前後部は左右方向に所定の張力が付与された状態でクランプすることができる。
したがって、スクリーンに前後左右方向の引張力を加えても、四隅部寄りの部位に歪みが生じるのを効率よく防止することができる。 (1) When the screen is clamped by the front / rear clamping device, both ends of the screen in the vicinity of the front / rear clamping device are clamped to apply a predetermined tension in the left / right direction. Since the clamping device is provided, the front and rear portions of the screen clamped by the front and rear clamping devices can be clamped in a state where a predetermined tension is applied in the left-right direction.
Therefore, even if a tensile force in the front / rear / right / left direction is applied to the screen, it is possible to efficiently prevent distortion from occurring in the portions near the four corners.

（２）前記（１）によって、スクリーンに所定の張力を付与した状態で前後左右部位をクランプすることができる。
したがって、スクリーンに均一な引張力を加えることができ、全体を均一な状態で枠体に固定することができる。 (2) According to the above (1), the front, rear, left and right parts can be clamped with a predetermined tension applied to the screen.
Therefore, a uniform tensile force can be applied to the screen, and the whole can be fixed to the frame body in a uniform state.

（３）前記（１）によって、前後部の補助クランプ装置を設けるだけでよいので、容易に製造することができるとともに、既存のスクリーン紗張装置にも本願発明を施すことができる。 (3) According to the above (1), it is only necessary to provide the auxiliary clamping device at the front and rear portions, so that it can be easily manufactured and the present invention can be applied to an existing screen tensioning device.

（４）請求項２も前記（１）〜（３）と同様な効果が得られる。 (4) In claim 2, the same effects as in the above (1) to (3) can be obtained.
