Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet body take-out device for adsorbing and sequentially taking out sheet bodies stacked in a container and loaded.

[0002]

2. Description of the Related Art Conventionally, a plurality of sheets, for example,
Widely used is a take-out device for accommodating and storing a film in which image information is recorded in a magazine, adsorbing and holding the film in the magazine by a suction plate, taking out the films one by one, and feeding them to the automatic developing device side. There is.

In this case, the suction plate is arranged so as to face a certain position with respect to the opening of the magazine, and after the film is sucked, it is displaced to a desired film transfer position. Moreover, it is said that it is preferable that the suction plate has a suction action at the leading end of the film, in order not to leave a trace of the suction disc on the main part of the film on which image information and the like are recorded.

From such a point of view, a magazine in which a plurality of films are stacked is arranged substantially vertically, and each film is dropped by gravity and abutted against the side wall portion on the lower end side of the magazine, so that different sizes can be obtained. Even if the film is a film, the suction disk can always carry out a constant suction action at a predetermined place of the film, and the tip of the film is aligned.

By the way, the films stacked in the magazine are often in close contact with each other due to static electricity or the like between the films, and a plurality of films may be taken out integrally. For this reason, normally, a separating member for peeling off another film which is in close contact with the film adsorbed on the adsorption disk is provided on the side wall portion on the lower end side of the magazine with which the leading end of the film abuts.

[0006]

However, if there is a defect in the loading state of the film in the magazine, or if two or more films are taken out at the same time when the film is taken out, the film will be inserted in the middle of the separating member. The tip is often caught. In this state, when the suction plate moves to the stacking position side of the film and tries to adsorb the film, this film is inclined because the leading edge of the film is caught by the separating member, and the film is sucked between the suction plate and the film. This will cause air leakage. As a result, it has been pointed out that a defective suction of the film is likely to occur, and the work of taking out the film cannot be performed reliably and efficiently.

The present invention solves this kind of problem, and even if the tip of the sheet body is caught by another member, the sheet body can be reliably returned to a predetermined stacking position, and It is an object to provide a sheet body take-out device having a simple structure.

[0008]

In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention is a sheet for adsorbing and sequentially taking out sheet bodies stacked and loaded in a container. A body take-out device, a suction board for sucking the sheet body, a moving mechanism for moving the suction board forward and backward with respect to the sheet body, an end surface of the sheet body on the take-out side from the container, and the suction side. Pressed to return to the stacking position by pressing the sheet body lifted from the stacking position and moving by being integrally provided with the suction plate under the action of the moving mechanism and positioned between the plates. Means and are provided.

According to a second aspect of the present invention, the pressing means includes a pressing member fixed to a holding member that holds the suction plate, and the end surface of the pressing member for pressing the sheet body is
It is characterized in that it is located in a direction away from the sheet body surface of the suction board from the sheet body suction surface.

In the invention according to claim 3 of the present invention, the pressing means further comprises a pressing member which is movable forward and backward with respect to the surface of the sheet body via an elastic member on a holding member for holding the suction plate. It is characterized by

The invention according to claim 4 of the present invention is the invention according to claim 1.
The sheet body take-out device according to any one of items 1 to 3, wherein a surface of the accommodation container that faces an end surface of the sheet body in the take-out direction forms a separation surface of the sheet body.

[0012]

In the sheet body take-out device according to the first aspect of the present invention, the pressing means moves to the sheet body side integrally with the suction plate under the action of the moving mechanism. At that time, if the end surface of the sheet body in the take-out direction is caught on the inner wall of the sheet body container, the pressing means located between the leading end of the sheet body and the suction cup presses the leading end side of the sheet body. Therefore, the sheet body whose front end is pressed is forcibly returned to the regular stacking position, and then securely held by the suction plate that moves integrally with the pressing means.

In the sheet body take-out device according to the second aspect of the present invention, the sheet body pressing end surface of the pressing member of the pressing means is located in a direction farther from the sheet body surface than the sheet body suction surface of the suction plate. Therefore, the leading end side of the sheet body that is caught by the separating member and the magazine stopper can be forcibly returned to the regular stacking position by being pressed by the pressing member located between the leading end of the sheet body and the suction plate. At the same time, when the sheet body is approached to adsorb the sheet body, the pressing end surface of the pressing member does not contact the sheet body and the sheet body is not damaged.

In the sheet body take-out device according to the third aspect of the present invention, since the pressing member is further movable back and forth with respect to the surface of the sheet body through the elastic body, the sheet body is surely returned to the regular stacking position. It is possible to prevent the sheet body from being damaged even when sucked by the suction plate.
