Description
【0001】[0001]
本考案は、印刷機に用紙を送る給紙装置の吹き足に関するものである。 The present invention relates to a blowing foot of a paper feeding device that feeds paper to a printing machine.
【0002】[0002]
従来、単葉紙に印刷をする時、積み重ねた紙束から、印刷機に1枚ずつ紙を送 る方法としては、ゴムローラーを回転させてその摩擦を利用して送る方法か、吸 盤で1枚だけ吸いつけ持ち上げて送る方法があった。ゴムローラーによる方法は 、2枚重なって送られることもあるが、吸盤で吸いつけ持ち上げて移動する方法 は、紙を確実に1枚だけ送ることができるので、産業用の印刷機械に多く使われ ている。 Conventionally, when printing on a single sheet of paper, the method of feeding the paper one by one from the stack of stacked sheets to the printing machine is to rotate the rubber roller and use the friction to feed it. There was a method of sucking only one sheet and lifting and sending it. The method using a rubber roller may send two sheets in an overlapping manner, but the method of sucking and lifting with a suction cup can move exactly one sheet of paper, so it is often used in industrial printing machines. ing.
【0003】 吸盤で吸いつけ持ち上げて紙を送る方式の給紙装置の一例として、図10に示 すような機構の装置がある。その動作は、図10と図10の装置を上から見た説 明のための図11において、先ず吸盤2〜5で紙14の端を吸いつけて、積み重 ねた紙の束から1枚だけそっと持ち上げる。次に、紙14と残りの紙束15の間 に吹き足11が入り込み、そこで矢印のように空気を吹き込んで、紙14を紙束 15からはがすようにして全体に持ち上げる。続いて吸盤6〜10が紙14を吸 引、支持して印刷機に向けて移動させるというものである。As an example of a paper feeding device that sucks and lifts a suction cup to feed paper, there is a device having a mechanism as shown in FIG. The operation is shown in FIGS. 10 and 11 for the purpose of explaining the apparatus viewed from above. First, one end of the stack of papers is sucked by sucking the end of the paper 14 with the suction cups 2 to 5. Just gently lift. Next, the blowing foot 11 enters between the paper 14 and the rest of the paper bundle 15, and air is blown therein as shown by the arrow so that the paper 14 is peeled from the paper bundle 15 and lifted up to the whole. Then, the suction cups 6 to 10 suck and support the paper 14 and move it toward the printing machine.
【0004】[0004]
しかし、図10の装置の正面からの説明図12に示すように、吸盤3と吸盤4 の間が離れているので吸盤7は紙14を吸いつけることができず、紙14を移動 するのに失敗し、そのため印刷機に紙が送られず、印刷機が自動的に停止してし まうことがあった。 However, as shown in FIG. 12 which is a front view of the apparatus of FIG. 10, since the suction cup 3 and the suction cup 4 are separated from each other, the suction cup 7 cannot suck the paper 14 and the paper 14 is moved. In some cases, it failed and paper was not sent to the press, and the press stopped automatically.
【0005】 本考案は、紙送りの失敗がない給紙装置のための吹き足を提供することを目的 とするものである。An object of the present invention is to provide a blowing foot for a paper feeding device without paper feeding failure.
【0006】[0006]
上記課題を解決するため、本考案の吹き足においては、横方向と同時に上方向 にも空気を吹き出すように形成するという手段を講じた。 In order to solve the above-mentioned problem, in the blow foot of the present invention, a means of forming air is blown out not only laterally but also upward.
【0007】[0007]
積み重ねられた単葉紙の上の1枚を負圧空気による吸盤によって吸い付けてそ の紙の端を持ち上げる。続いて、持ち上げられた紙の下に本考案の吹き足の先端 を入れて、空気を横方向と上方向に送って紙全体を持ち上げる。水平に持ち上げ られた紙を前記吸盤とは別の吸盤によって吸い上げ,それを水平に支持しながら 移動させ、印刷機に紙を送る。 Suck one of the stacked sheets of paper with a suction cup of negative pressure air and lift the edge of the paper. Then, insert the tip of the blowing foot of the present invention under the lifted paper, and blow the air laterally and upward to lift the entire paper. The horizontally lifted paper is sucked up by a suction cup other than the suction cup, moved while supporting it horizontally, and the paper is sent to the printing machine.

以下に本考案を、実施例を示した図面に基づいて詳細に説明する。 図1は本考案にかかる吹き足の一実施例の斜視図、図2は図1の吹き足を使用 した給紙装置の斜視図,図3・図5・図8は図2の給紙装置を上方向から見た説 明図,図4・図7は同じ給紙装置を正面から見た説明図,図6は図5のA−A線 断面図である。 Hereinafter, the present invention will be described in detail with reference to the drawings showing an embodiment. 1 is a perspective view of an embodiment of the blowing foot according to the present invention, FIG. 2 is a perspective view of a paper feeding device using the blowing foot of FIG. 1, and FIGS. 3, 5, and 8 are the paper feeding devices of FIG. FIG. 4 is an explanatory view of the same sheet feeder as seen from the front, and FIG. 6 is a sectional view taken along the line AA of FIG.
【0009】 本考案にかかる吹き足1の外形はアヒルの足に似ており、パイプ1cを通って 送られた空気が扇形の根元の部分で分岐して、扇の先端に当たる部分から吹き出 す。空気の吹き出し口の中央の3個の吹き出し口1aは上向きに取り付けられ、 空気を上方向に吹き出す。また、両端の吹き出し口1b,1bは空気を横方向に 吹き出す。ここで、ネジ1dは取り付けのためのものである。The outer shape of the blowing foot 1 according to the present invention is similar to that of a duck's foot, and the air sent through the pipe 1c branches at the root of the fan and blows out from the part that hits the tip of the fan. The three air outlets 1a at the center of the air outlets are attached upward and blow out the air upwards. Further, the air outlets 1b, 1b at both ends blow out air in the lateral direction. Here, the screw 1d is for attachment.
【0010】 吹き足1は給紙装置に図2のように配置され、取り付けられている。 図2の給紙装置の吹き足1の作動前の状態を示す図3において、吸盤は吹き足 1から近い順に一列に、吸盤2〜5、続いて吸盤6〜8、続いて吸盤9〜10が 並んでいる。 図3,図4は紙送り前の段階である。先ず、図3,図4の状態から吸盤2〜5 が紙12を吸いつけ持ち上げる。この時、吸盤2〜5は一体に、上下方向にのみ 移動する。The blow foot 1 is arranged and attached to the paper feeding device as shown in FIG. In FIG. 3, which shows a state before the operation of the blow feet 1 of the sheet feeding device of FIG. 2, the suction cups are arranged in a line in the order of being closer to the blow feet 1, the suction cups 2 to 5, the suction cups 6 to 8, and then the suction cups 9 to 10. Are lined up. 3 and 4 show the stage before the paper is fed. First, the suction cups 2 to 5 suck up the paper 12 and lift it from the state shown in FIGS. At this time, the suction cups 2 to 5 move integrally and only in the vertical direction.
【0011】 続いて、図5,図6,図7に示すように、持ち上げられた紙12の下に吹き足 1の先端部分が入り込み、吹き出し口1a,1bから上方向と横方向にそれぞれ 空気を吹き出す。同時に、吸盤6〜10が吹き足1に接近する方向に移動する。 なお、吸盤6〜10は一体で前後方向にのみ移動する。ここで、各図に記した矢 印は空気の流れを示すものである。Subsequently, as shown in FIGS. 5, 6 and 7, the tip end portion of the blowing foot 1 enters under the lifted paper 12 and blows air upward and laterally from the outlets 1a and 1b, respectively. Blow out. At the same time, the suction cups 6 to 10 move in a direction approaching the blow foot 1. The suction cups 6 to 10 move as a unit only in the front-rear direction. Here, the arrow shown in each figure shows the flow of air.
【0012】 吸盤2〜5によって持ち上げられた紙12の下部に、吹き足1によって空気が 吹き込まれると、紙12は紙束13からはがされるように持ち上がる。全体に持 ち上げられた紙12は、吸盤6〜10に吸いつけられる。この時、紙12は図7 に示すように9個の吸盤で吸い付けられている。従来の吹き足では吸い付けに失 敗することがあった吸盤7も、吹き足1の上向きの吹き出し口1aからの風によ って上に持ち上げられるので、紙12をうまく吸い上げる。When air is blown into the lower part of the paper 12 lifted by the suction cups 2 to 5 by the blow foot 1, the paper 12 is lifted so as to be peeled from the bundle of papers 13. The paper 12 lifted up as a whole is sucked by the suction cups 6 to 10. At this time, the paper 12 is sucked by nine suckers as shown in FIG. The sucker 7 that may have failed to suck in the conventional blowing foot is also lifted up by the wind from the upward blowing outlet 1a of the blowing foot 1, and thus sucks the paper 12 well.
【0013】 次に、吸盤2〜5が吸いつけを止め、吸盤6〜10が紙12を吸いつけながら 、図8に示す位置に移動し、次に吸盤6〜10が吸いつけを止める。 このようにして、紙12は次の印刷の段階に送られる。 このようにして、各部分は図3,図4に示す最初の位置にもどり、同じ動作を 繰り返す。Next, the suction cups 2 to 5 stop the suction, the suction cups 6 to 10 move to the position shown in FIG. 8 while sucking the paper 12, and then the suction cups 6 to 10 stop the suction. In this way, the paper 12 is sent to the next printing stage. In this way, each part returns to the initial position shown in FIGS. 3 and 4, and the same operation is repeated.
【0014】 図9は本考案にかかる吹き足の別実施例で、横方向の吹き出し口1eとは別に 、新たに上方向に空気を吹き出すための吹き出し口1fを設けたものである。FIG. 9 shows another embodiment of the blowing foot according to the present invention, in which a blow-out port 1f for blowing air upward is newly provided in addition to the blow-out port 1e in the lateral direction.
【0015】[0015]
以上説明したように、本考案の吹き足は横方向への空気の吹き出しと同時に、 紙を持ち上げるために上方向にも空気を吹き出すようにしたので、紙送りのため の吸盤に紙が密着し、紙送りの失敗がなくなる。 As described above, since the blowing foot of the present invention blows out the air in the lateral direction and also blows the air upward to lift the paper, the paper sticks to the suction cup for feeding the paper. , Paper feed failure is gone.
