本発明はスクリーン版に設定した衝と被印刷体

定位置に捺染するスクリーン印刷における被印刷
体とスクリーン版の位置整合装置に関する。[Detailed Description of the Invention] The present invention prints a pattern formed at a predetermined position on a screen plate onto a predetermined position on a printing material by matching the impact set on the screen plate with the impact provided on the printing material. The present invention relates to a position alignment device for a printing medium and a screen plate in screen printing.
従来から、スクリーン版に形成したパターンを

らかじめ、スクリーン版と被印刷体の位置関係を
規制しておくのが普通である。 Conventionally, in screen printing machines that print a pattern formed on a screen plate onto a predetermined position of a printing material on a printing table, the positional alignment between the screen plate and the printing material is usually achieved by using a constant impact set on the screen plate. Usually, the positional relationship between the screen plate and the printing material is regulated in advance so that the registration mark (register mark) matches the position provided on the printing material.
しかして、この両者の位置整合については種々
の整合手段が考えられるが、被印刷体のサイズの
不統一や、衝の設定位置の不正確さなどから印刷
処理の過程で被印刷体とスクリーン版の衝が常に
正確な合致するとは限らず、ここにより合理的な
整合手段についての提案が出現することになる。 Various alignment means can be considered to align the positions of the two, but due to inconsistency in the size of the printing material and inaccuracy in the position of the offset, the printing material and the screen plate may be affected during the printing process. It is not always the case that the oppositions of , , and , are an exact match, and proposals for more rational means of matching will emerge.

処理する印刷工程では到底、採用しえないもので
ある。 An extremely basic alignment method is to visually adjust the alignment of the printing material being carried onto the printing table and the screen plate until they match, but this alignment mechanism does not It has drawbacks in terms of speed and accuracy, and cannot be used in continuous, automatic printing processes.

欠点がある。 Alignment is also carried out by preparing a reference printing material in advance, using this material as an opposition, and using electrical or mechanical means to match the printing material to be processed later with the opposition. There are means. Advances have been made in making this registration method applicable to continuous, automated printing processes;
This is inconvenient because it is necessary to prepare in advance the printing material that is to be used as a collision, and the printing material that is to be used as a collision and the printing material that will be processed later may be significantly different in size or other points. Naturally, it cannot be applied to products whose conditions are different from those that have become known, and has the disadvantage that, at best, it can only be expected to work effectively in units of a certain lot within the same standard.
更にまた、被印刷体とスクリーン版の衝の整合
手段において一般には、電気的な検知手段の介在
とその利用がより合理的であるとされているが、
この電気的手段は通常、複数の独立したセンサー
例えば、フオトトランジスターがセツトになつて
一つの検知手段として利用される場合が多い。 Furthermore, it is generally considered more rational to include and utilize electrical detection means as a means for aligning the opposition between the printing material and the screen plate;
This electrical means is usually a set of a plurality of independent sensors, such as phototransistors, and is often used as a single detection means.

Therefore, when using this detection means, the printing material or the
The screen plate must be moved and adjusted a considerable number of times, which increases the mechanical complexity and makes it impossible to achieve higher positional alignment accuracy.

である。 The present invention is intended to eliminate the various drawbacks seen in these conventional techniques, and is to align the position of the printing material and the screen plate that are conveyed to the printing table via a solid-state image sensor represented by a CCD camera. The aim is to do this more accurately, quickly and easily.

る。以下、固体撮像素子１の説明はCCDカメラ
の説明によつて行なうこととする。 A solid-state image sensor 1 is fixed to a printing table 2, and its lens portion 1b is directed above the table. The solid-state image sensor 1 here is a so-called CCD.
It is typically a camera, and images can be taken out from photo sensors arranged vertically and horizontally on the light-receiving surface with high accuracy in the micro level, and are suitable for setting x-y axis coordinates in position detection. be. Hereinafter, the solid-state image sensor 1 will be explained by referring to a CCD camera.

ボ印４ａが形成してある。 A CCD camera 1 is fixed to a printing table 2, and its lens portion 1b faces a printing material 3 carried onto the printing table 2. A silk screen 4b on which a predetermined pattern 4d is formed is pasted on a frame 4c. It also faces the screen version 4. A through hole 3a is formed in the printing material 3, and a register mark 4a is formed on the screen plate 4, which should be in opposition with respect to the CCD camera 1. It has been done.

軸上距離y1、y2およびｘ軸上の距離ｘに対して
次の関係式が成り立つ関係にある。 Therefore, reference point 1 set on CCD camera 1
The relationship between the distances v1 and v2 on the y-axis and the distance u on the x-axis between a and the opposition 4a provided on the screen plate 4 (see Fig. 3) is measured in advance by the CCD camera 1 and stored in memory. This value is stored in the device 5 and acts as a constant reference value for the relationship between the offset 3a of the printing medium 3 and the reference point 1a of the CCD camera 1. That is, y between the reference point 1a of the CCD camera 1 and the offset 3a of the printing material 3
The following relational expression holds true for the on-axis distances y1 and y2 and the distance x on the x-axis.
ｘ＝ｕ−ｘ、y1＝v1−y1、y2＝v2−y2 （第３図参照）。 x=u−x, y1=v1−y1, y2=v2−y2 (See Figure 3).

間することはない。 The position of the printing material 3 carried onto the printing table 2 in its advancing direction is regulated by a stopper pin 6 that is removably attached to the printing table 2, and its position in the direction perpendicular to the advancing direction is regulated by a fixed side plate 7. This is done by the action of the moving side plate 8. This initial positional regulation on the printing table 2 is done fairly accurately in relation to the screen plate 4, and therefore, as long as the printing material 3 is conveyed onto the printing table 2 in a normal state, The through hole 3a, which should serve as a barrier, is not separated from the lens portion 1b of the CCD camera 1 fixed at a predetermined position on the printing table 2.

い。 Note that the abutment 3a of the printing material 3, which is significant in relation to the reference point 1a of the CCD camera 1, does not necessarily have to be a through hole drilled in the printing material 3. The edge portion 3b may be used as the opposite. In short, it is sufficient that an image forming brightness and darkness is formed on the CCD camera 1, and it is preferable that the through hole 3a formed in the printing material 3 is simple and convenient for handling. In addition, in order to make the brightness and darkness captured by the CCD camera 1 clearer, it is necessary to
It is advisable to install a light source 9 that emits light toward.

A vertical cursor 15 and a horizontal cursor 16 that intersect at the center of the screen are displayed (the fourth
(see figure). Therefore, if this monitor TV 12 is installed, the distance relationship between the reference point 1a of the CCD camera 1 and the opposition 4a of the screen plate 4 can be seen on the screen.
The distance relationship y1, y2, x between v1, v2, u, and the reference point 1a of the CCD camera 1 and the offset 3a of the printing medium 3 can be seen at a glance, and the amount of deviation between the two can be grasped intuitively.

定する。 Now, when the printing material 3 is carried onto the printing table 2, the stopper pin 6 protrudes onto the printing table 2 to regulate the position of the printing material 3 in the advancing direction.
Almost simultaneously, the movable side plate 8 moves toward the fixed side plate 7 to regulate its position in the direction perpendicular to the direction of movement. Thereafter, the stopper pin 6 descends below the surface of the printing table 2, and the printing table 2 rises slightly to remove the printing material from the belt conveyor 17.
When separated, the negative pressure suction hole 18 on the surface of the table 2
Then, the printing material 3 is fixed onto the table 2 by vacuum suction.

先記のとおりである。 On the other hand, the CCD camera 1 receives an image of the through hole 3a provided in the printing material 3 as a collision, and transmits this signal to the calculation device 11 in charge of calculation, and sends the signal to the reference point 1a of the CCD camera 1 and the collision between the printing material. The distances y1, y2 on the y-axis between the through hole 3a and the distance x on the x-axis as
Then, the distances v1 and v2 on the y-axis between the reference point 1a of the CCD camera 1 and the registration mark 4a as the opposite on the screen plate 4, which have been stored in the storage device 5 in advance, and the distances on the x-axis This is evaluated in relation to the distance u, and furthermore, the amount of deviation occurring between the two is calculated. Therefore, the amount equivalent to this deviation is the pulse motor 10, that is, PY1, PY2, PX
The problem is solved by moving the screen plate 4 through It is guaranteed that the print will be printed at a predetermined position on the printing material 3. At this time, if a monitor TV 12 is installed, the distance relationship between the reference point 1a of the CCD camera 1 and the offset 4a of the screen plate 4, which will serve as an absolute reference value, will be useful.
The distance relationship y1 between and the reference point 1a of the CCD camera,
As mentioned above, y2 and x can be grasped intuitively.

うになる。 As described above, the present invention utilizes a solid-state image sensor, such as a CCD camera, and uses a reference point set on the solid-state image sensor as a common term, and calculates the relational distance between this reference point and the opposition of the screen plate, and the distance between the reference point and the opposite of the screen plate, and Since the distance relative to the opposition is compared and calculated, and the amount of deviation that arises from that is resolved by moving the screen plate, it goes without saying that there is no need to plan in advance the presence of the printing material that should be the opposition. , which cannot be obtained with conventional analog detection means that align the positions of multiple transistors at the light receiving ratio.
It has become possible to easily obtain an alignment device that can be expected to perform accurate and rapid processing. Furthermore, according to the present invention, the position alignment is performed by moving the screen plate, which has a relatively simple operation configuration, so that a simpler device structure can be obtained, and a more sophisticated We can expect good positional alignment. Furthermore, it becomes easier to set the x-y coordinates when calculating the amount of misalignment between the printing material and the screen plate, and it also makes it possible to install a monitor TV. The amount of deviation can be grasped visually.
