BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed material feeding device for automatically feeding back covers one by one into a plastic packaging container in which a CD such as an optical disk is housed, and more specifically, to a hopper vertically oriented. The entire back cover, which is laminated and supplied to, can be pressed uniformly.

[0002]

2. Description of the Related Art Conventionally, as a method for automatically supplying the back covers one by one into a plastic packaging container in which CDs are housed, as shown in FIG. Part is a flat push plate 3
A method is adopted in which the sheet is pressed by 2 and adsorbed one by one from the back cover 31 at the forefront by an unillustrated suction pad and stored in a packaging container.

[0003]

By the way, when a label, a sticker, a sample, or the like is attached to each of the above-mentioned back covers 31 for each sheet,
Since the thickness of the back cover 31 itself increases, the back cover 31 is inclined as shown in FIG. 7 in a stacked state, and it becomes difficult to uniformly press the entire back cover 31 with the pressing plate 32. Therefore, the back cover jumps out of the hopper, and an obstacle such as the back cover being clogged at the hopper lower ejection port may occur, and the automatic supply may be temporarily stopped. There is such a problem.

The present invention has been made to solve the above-mentioned problems, and even when the back cover is tilted, the entire back cover can be pressed uniformly, and automatic supply can be performed smoothly and reliably. An object of the present invention is to obtain a printed material feeding device.

[0005]

In order to achieve the above-mentioned object, the apparatus for feeding printed materials to be stacked and supplied according to the present invention has a structure in which the printed materials are stacked in a vertical direction and the rearmost part is pressed by a pressing means so that the printed materials are from the front row. In a device for feeding printed matter, which is sucked and conveyed one by one by a suction head, a pressing unit has a pressing unit main body, and a fan-shaped unit in which the pressing unit is supported by a supporting shaft so as to be horizontally swingable. It is composed of a pressing arm and a plurality of pressing rollers for pressing the printed matter on the tip side of the pressing arm.

According to the above-described printed material feeding apparatus, the pressing arm swings about the support shaft with respect to the inclination of the stacked back covers and the pressing roller can uniformly press the entire back cover.

Further, since the back cover is biased in the pressing direction by the constant load spring, the back cover can always be pressed with a constant pressing force.
