全に空気を吹き入れる。The sheet feeding device of the conventional sheet-fed printing press is composed of a soccer (21) (22) and a blowing foot (11) as shown in FIGS. 3 and 4. Among them, the soccer (21) (22) sucks up the sheet (31) by a pump and feeds the sheet (31) one by one into the delivery roller (34). In addition, the blowing foot (11) assists the work of the soccer (21) (22), and the sheet (31) that is being fed at the top and the other sheet (32) before being fed.
Blow air from the side opposite to the holding side to separate the
Make a gap. If the gap is opened, insert the tip of the blow foot (11) including the blow mouth (12) between the sheet (31) being fed and the sheet (32) before being fed, and While pressing the sheet (32) before feeding at the bottom of 11), blow air completely to the delivery roller (34).

わらない事があった。(Problems to be solved by the invention) In the sheet feeding device of the conventional sheet-fed printing press, the sheet before feeding is pressed by the blowing foot. The paper blistered, and the air blown from the air outlet collided with it, sometimes preventing the air from being completely transmitted to the holding side.

間の間隙が狭まり、その間に吹き足自体が入らず、給紙
前の枚葉紙を紙押えできない事もあった。Further, in the blowing foot, even if the blowing port is simply set apart from the bottom, the positional relationship between the blowing port and the bottom that presses the paper is fixed. Therefore, depending on the paper thickness and the quality of the sheet, the position of the sheet before feeding may rise to the upper position when the blown feet are separated. In some cases, the gap between the sheet and the sheet was narrowed, and the blow foot itself did not enter between the sheets, and the sheet before feeding could not be pressed.

距離の調整手段を設ける。(Means for Solving the Problem) In order to solve the above-mentioned problems, a sheet feeding device of a sheet-fed printing press including at least a football that works to suck up a sheet and a blowing foot that separates the sheet. Further, a paper pressing plate is provided below the blowing foot, and means for adjusting the distance between the blowing foot and the paper pressing plate is provided.
この様にした給紙装置を用いて、枚葉紙に適した距離に
吹き足と紙押え板との間を設定する。By using the paper feeding device thus configured, the distance between the blow foot and the paper pressing plate is set to a distance suitable for the sheet.

つ。The sheet feeding device of the sheet-fed printing press of the present invention is a soccer (21) (2
It consists of 2), the blowing foot (11) and the paper holding plate (13).
Of these, soccer consists of the first soccer (21) and the second soccer (22), both of which are in the top sheet (3).
It has the function of sucking up 1) and delivering it to the roller (34).

Further, the blow foot (11) is connected to the upper base (18), and the connection is such that the vertical position can be adjusted by the vertical position adjusting knob (17). . Further, with respect to the paper pressing plate (13), the distance from the blowing foot (11) can be adjusted by moving the rod (15) by loosening the fixing screw (16). It is possible to adjust the height of the air outlet (12), which is the position where the air is blown out from.

た。Next, a case where a sheet is actually fed will be described. The first football (21) with the blow foot (11) side of the sheet (31) being fed
To lift. At this time, the sheet (31) being fed and the sheet (32) not being fed are not completely separated. For this reason, air is blown from the outside through the air outlet (12) of the air blower (11) to separate the sheets into a sheet (31) being fed and a sheet (32) before being fed. Divide and put the blow foot (11) in this gap. At this time, the paper pressing plate (13) is also inserted at the same time, and then the paper pressing plate (13) is pressed to fix the sheet (32) before feeding, and then the blowing foot (11) is blown out from the air outlet (12). Air is blown out from the sheet feeding roller (34) side to completely separate the sheet (31) being fed and the sheet (32) not being fed. At this time, since the sheet (32) before being fed is being held by the paper holding plate (13), it is sent out from the paper holding plate (13).
Side sheet (32) before paper feeding has blister (33),
As in this example, the height of the air outlet (12) is adjusted beforehand, so the air blown out from the air outlet (12) should not reach the sheet delivery roller (34) side due to the blister (33). Disappears. In such a case, the second soccer (22) also works at the same time, and it becomes possible to completely separate the sheet (31) which is being fed and the sheet (32) which is not yet fed. This makes it possible to send out the sheets one by one and pass them to the roller (34).
尚、本実施例では吹き足と紙押え板の間隙を、紙押え板

吹き足に対する位置を決めても良い事は当然である。In this embodiment, the gap between the blowing foot and the paper pressing plate was adjusted by loosening the fixing screw for fixing the sliding rod standing upright on the paper pressing plate. It is also possible to provide several through holes in the above and insert a pin into the through hole position at an appropriate position to determine the position of the paper pressing plate with respect to the blowing foot. Further, as a gear system, it is natural that the position of the paper pressing plate with respect to the blowing foot may be determined by sliding a general gear.
その他本考案は、その要旨の範囲内で種々変形実施可能
な事は当然である。In addition, the present invention can be variously modified within the scope of the invention.

押え板の間隙を設定する事が出来る。(Effect of the Invention) With the present invention, it is possible to freely set the positions of the blowout opening of the blower foot and the paper pressing plate. Therefore, the gap between the air outlet and the paper pressing plate can be set in accordance with the gap between the sheet before feeding and the sheet during feeding.
