本発明は、吸着盤に吸着保持されたシート体の吸着枚数
によって吸着盤の搬送動作を変更せしめ、シート体の複
数枚枚葉を回避することを可能としたシート体枚葉制御
方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention changes the conveying operation of a suction cup depending on the number of sheet bodies suctioned and held by a suction cup, thereby avoiding multiple sheet bodies. The present invention relates to a sheet body single wafer control method that makes it possible to do this.
［従来の技術］

送する。[Prior Art] A sheet body single-fed apparatus suction-conveys a sheet body, for example, a photographic material, to a predetermined position under the displacement action of a suction cup communicating with a vacuum supply source. In other words, sheets are taken out one by one from a supply magazine that stores stacked sheets coated with a photosensitive material on one side, such as photographic photosensitive materials (for example, X-ray film, etc.) and graphic arts films, and then sent to the next process. (for example, exposure, development, etc.).

隙間が開くので、その変位量如何で複数枚枚葉か否かが
判別される。In this case, if a plurality of sheet bodies are brought into close contact with each other due to static electricity or the like, these plural sheet bodies will be conveyed to the next process. In order to avoid this, conventionally, the sheet body sucked by a suction cup is once introduced into a sheet body detection means consisting of a pair of rollers. It is detected whether or not. That is, the thickness of the sheet that is about to pass through the pair of rollers is set in advance in the thickness displacement meter, and when two or more sheets are held between the pair of rollers, the thickness displacement is measured. Since the gap between the rollers of the pair of rollers is larger than the set range of the meter, it is determined whether or not a plurality of sheets are being processed based on the amount of displacement.

を得なかった。[Problems to be Solved by the Invention] However, in the sheet body single-fed apparatus according to this prior art, the suction cup is always attached to the sheet bodies without considering the remaining amount of the sheet bodies to be laminated and single-fed. In order to displace the sheet by a certain stroke, press it, and then adsorb it, the air between the adjacent sheet bodies is forced out, and as a result, on the contrary,
The sheets are brought into close contact with each other. As a result, a plurality of sheets were attracted at the same time, interfering with the next single sheet operation inside the apparatus, and the apparatus had to be stopped to eliminate this inconvenience.

。In addition, the thickness of the sheet body is set in advance on the thickness displacement meter to detect multiple sheets of the sheet body, but normally the thickness of the sheet body as a photographic light-sensitive material is thin < (0.2 mm). (front and back) The gap in connection accuracy between the roller and the thickness displacement meter cannot be fully covered, and especially for sheets that have been transported in two sheets, it is difficult to determine whether the sheet is one sheet or not because the sheet is too thin. It was difficult to accurately determine the thickness using a thickness displacement meter.

提供することを目的とする。The present invention solves this kind of problem by providing a slight gap between the suction cup that sucks the sheet body and the sheet body, so that the sheet body can be reliably loaded one by one without pressing the sheet body. It detects the number of sheets sucked at a predetermined position, and if multiple sheets are left, once the sheet body is removed from the suction cup, the suction operation is performed again. It is an object of the present invention to provide a sheet body single wafer control method that makes it possible to avoid a plurality of wafers without stopping electricity production.

, point E in Figure 4). During this time, the blowing means 62 blows compressed air sent from the pipe 64 onto the end surface of the sheet body. During this time, the roller 60 of the sheet body pressing section 50
contacts the corners of the photographic light-sensitive material 14 and causes it to curve, so when a plurality of sheets are loaded, air is introduced between adjacent photographic light-sensitive materials 14 to prevent the second and subsequent sheets from being exposed. The material 14 is peeled off.

m/5ec) (Step 8 in Figure 2, F in Figure 4)
point), it is confirmed by the sheet body detection means 48 whether or not a plurality of photographic materials 14 are sucked (step 9 in FIG. 2). Here, confirmation of whether one sheet or a plurality of sheets of the photographic light-sensitive material 14 has been carried is carried out by the sheet body sheet detection means 4.
The upper end of the detection rod 54 is determined by the balance between the elastic force of the compression coil spring provided at 8 and the rigidity of the photosensitive material 14 itself, depending on whether the sensor 56 is actuated. That is, if the photographic material 14 sucked by the suction cup 16 is one piece, the photographic material 14 is bent downward at the lower end of the detection rod 54, and the detection rod 54 is inserted into the optical sensor 56. without its upper end entering.
The sensor 56 does not emit a signal. On the other hand, when a plurality of sheets are formed, the photosensitive material I4 increases in rigidity, and the upper end of the detection rod 54 faces the sensor 56.
そこで、単数枚の枚葉であることが確認されると、吸着
盤１６を高速で基準位置まで上昇させ（第２図ステップ

処理装置に搬送させる（第２図ステップ１１）。Therefore, when it is confirmed that the sheet is a single sheet, the suction cup 16 is raised to the reference position at high speed (step 10 in Figure 2, point G in Figure 4), and the next step, for example, automatic development, is carried out. It is transported to a processing device (step 11 in FIG. 2).
これに対し、第２図ステップ９で吸着盤１６に吸着され

５図Ｈ点）。On the other hand, when it is detected in step 9 of FIG. 2 that a plurality of photosensitive materials 14 are attracted to the suction cup 16, the suction cup 16 is again displaced at high speed in the direction of the suction position (
Step 12 in Figure 3), adsorb at the predetermined position (5th target point)! ! 16, then a suction pump (not shown) is stopped, and, for example, a solenoid valve is activated to perform a vacuum breaking action, thereby detaching the plurality of photographic materials 14 that had been suctioned and held by the suction cup 16. (Step 13 in Figure 3, point H in Figure 5).

光材料１４を吸着する操作を繰り返す（第５図Ｂ点）。Through this operation, the sheet detection means 48 detects whether or not the photographic material 14 is separated from the suction cup 16 (step 14 in FIG. 3). When the photographic material 14 is separated from the suction cup 16, , the suction cup 16 is displaced at high speed in the direction of the suction position (Step 15 in Figure 3, A in Figure 5).
point), then reduce the descending speed of the suction cup 16 (step 16) in FIG. The operation of adsorbing the material 14 is repeated (point B in Figure 5).

うようにしてもよい。Note that when it is detected that a plurality of photosensitive materials 14 are sucked on the suction cup 16, the suction cup 16 remains in a vacuum state without performing steps 12 to 16, that is, A suction cup 6 with a plurality of photosensitive materials 14 suctioned into the supply magazine 1
2 side at high speed to approach the photographic photosensitive material 14. Then, the descending speed of the suction cup 16 is reduced, and the suction cup 16
After stopping with a slight gap maintained between the photosensitive material 14 and the photosensitive material 14, steps 6 to 9 may be performed again.

枚葉することが可能になる。The displacement speed of the suction cup is decelerated near the sheet body, and the sheet body is suctioned while a gap is maintained between the suction cup and the sheet body, so the stacked sheet bodies are pressed. This makes it possible to reliably print a thin film-like sheet body one by one without having to do anything.
また、複数枚のシート体の吸着が確認された場合には、
所定位置で吸着ポンプを停止し、吸着盤から複数枚枚葉
されていたシート体を離脱させ、あるいは離脱の有無に
拘らず、再度吸着盤を吸着位置方向へ変位して吸着を再
開することにより、装置を停止せずに自動的に枚葉動作
を遂行し、−枚のシート体を所望の位置に搬送すること
ができる。従って、シート体の枚葉効果を一層向上させ
ることが可能となる。In addition, if multiple sheets are confirmed to be adsorbed,
By stopping the suction pump at a predetermined position, detaching multiple sheets from the suction cup, or displacing the suction cup in the direction of the suction position again and restarting suction, regardless of whether the sheets have been detached or not. , it is possible to automatically carry out single-sheet operation without stopping the apparatus, and to transport -sheets to a desired position. Therefore, it becomes possible to further improve the single wafer effect of the sheet body.
