Description

本発明は,連続用紙にテンションを与えるテンション装置に関する発明である。   The present invention relates to a tension device that applies tension to continuous paper.

インクジェットプリンタの印刷に用いる連続用紙の印刷面に異物(例えば,小さな紙片)があると印刷不良の原因になるため,エアを噴射するエアノズルをインクジェットプリンタに取り付け,印刷前の連続用紙の印刷面にある異物を除去することがある。   If there is a foreign object (for example, a small piece of paper) on the printing surface of the continuous paper used for printing with an inkjet printer, it may cause printing failure. Therefore, an air nozzle that injects air is attached to the inkjet printer, Some foreign matter may be removed.

印刷前の連続用紙の印刷面にエアを噴射するエアノズルを取り付けることで,印刷前の連続用紙の印刷面にある異物を除去できるが,エアノズルが噴射するエアによって連続用紙が微動し,連続用紙が蛇行することがある。   By attaching an air nozzle that jets air to the printing surface of the continuous paper before printing, foreign matter on the printing surface of the continuous paper before printing can be removed. It may meander.

連続用紙の蛇行を防止するためには,エアノズルを取り付ける箇所の連続用紙にテンションを与えるテンション装置を新たに設置すればよい。連続用紙にテンションを与えるテンション装置として,特許文献1のように,連続用紙の搬送に用いるロールの回転に抵抗を与える装置が知られているが,このようなテンション装置を既存のインクジェットプリンタに取り付けるには,インクジェットプリンタの大幅な改造が必要になる。   In order to prevent the continuous paper from meandering, a tension device that applies tension to the continuous paper at the location where the air nozzle is attached may be newly installed. As a tension device that applies tension to continuous paper, a device that provides resistance to rotation of a roll used for transporting continuous paper is known as in Patent Document 1, but such a tension device is attached to an existing inkjet printer. Will require a major modification of the inkjet printer.

また,インクジェットプリンタを大幅に改造することなく,連続用紙にテンションを与えるテンション装置の機構として,特許文献2で開示されているテンションパッドのような機構も考えられるが,テンションパッドのような機構では,連続用紙に摩擦力を与えるパッドを連続用紙の上下から直接押し付けるため,連続用紙に傷が付いてしまう。   Further, a mechanism such as a tension pad disclosed in Patent Document 2 can be considered as a mechanism of a tension device that applies tension to continuous paper without significantly remodeling the ink jet printer. Because the pad that gives frictional force to the continuous paper is pressed directly from the top and bottom of the continuous paper, the continuous paper is damaged.

連続用紙上の異物を除去するためにインクジェットプリンタに設置するエアノズルを利用して,連続用紙にテンションを与えることができれば,連続用紙上の異物を除去と同時に,連続用紙にテンションを与えることができるため,本発明は,エアノズルが噴射するエアを利用して連続用紙にテンションを与えるテンション装置を提供することを目的とする。   If tension can be applied to continuous paper by using an air nozzle installed in an inkjet printer to remove foreign matter on continuous paper, it can be applied simultaneously with removal of foreign matter on continuous paper. Therefore, an object of the present invention is to provide a tension device that applies tension to a continuous sheet using air ejected from an air nozzle.

上述した課題を解決する本発明は,インクジェットプリンタの給紙部と印刷部の間に設置するテンション装置であって,連続用紙の上側と下側から連続用紙を挟み込むようにエアを噴射する一対のエアノズルを,連続用紙の左右それぞれに配置し,前記一対のエアノズルの間を通過する連続用紙の左右端が,前記一対のエアノズルが噴射するエアによって挟み込まれる格好にすることで,前記一対のエアノズルが噴射するエアの圧力による摩擦力を利用して連続用紙にバックテンションを与え,更に,前記一対のエアノズルが噴射するエアが連続用紙の表裏面に流れることにより,連続用紙の表裏面にある異物を除去するように構成したことを特徴とするテンション装置である。
The present invention that solves the above-described problems is a tension device installed between a paper feeding unit and a printing unit of an inkjet printer, and a pair of air jets that inject continuous air from above and below continuous paper. Air nozzles are arranged on the left and right sides of the continuous paper, respectively, and the left and right ends of the continuous paper passing between the pair of air nozzles are sandwiched by the air ejected by the pair of air nozzles, so that the pair of air nozzles A back tension is applied to the continuous paper using the frictional force generated by the pressure of the air to be ejected, and further, the air ejected by the pair of air nozzles flows on the front and back surfaces of the continuous paper. The tension device is configured to be removed.

本発明に係るテンション装置では,一対のエアノズルが噴射するエアの圧力によって連続用紙の左右には摩擦力が発生する。この摩擦力は,連続用紙を搬送する際の抵抗になるため,テンション装置を設置した箇所の連続用紙にテンションが発生することができるようになる。また,本発明に係るテンション装置によれば,一対のエアノズルの間を通過する連続用紙には上下からエアが噴射されるため,このエアによって連続用紙の表裏面にある異物を吹き飛ばし,連続用紙の表裏面にある異物を除去できる。   In the tension device according to the present invention, a frictional force is generated on the left and right of the continuous paper by the pressure of the air ejected by the pair of air nozzles. Since this frictional force becomes a resistance when the continuous paper is conveyed, tension can be generated on the continuous paper at the place where the tension device is installed. Further, according to the tension device according to the present invention, air is sprayed from above and below on the continuous paper passing between the pair of air nozzles, so that the foreign matter on the front and back surfaces of the continuous paper is blown off by this air. Foreign matter on the front and back surfaces can be removed.

図1は,本実施形態に係るテンション装置1の設置場所を説明する図である。また,図2は,本実施形態に係るテンション装置1の構造を説明する図で,図2(a)は,本実施形態に係るテンション装置1の斜視図,図2(b)は,本実施形態に係るテンション装置1を正面から見た図である。   FIG. 1 is a diagram for explaining an installation place of the tension device 1 according to the present embodiment. FIG. 2 is a diagram for explaining the structure of the tension device 1 according to this embodiment. FIG. 2A is a perspective view of the tension device 1 according to this embodiment, and FIG. It is the figure which looked at the tension device 1 concerning a form from the front.

本実施形態に係るテンション装置1は,インクジェットプリンタ2内の連続用紙3にテンションを与えるために,インクジェットプリンタ2に設置する装置である。図1で図示したインクジェットプリンタ2は,連続用紙3をインクジェットプリンタ2に供給する給紙部20、複数のプリントヘッドを有する印刷部21,印刷部21で印刷した連続用紙3を乾燥する乾燥部22,印刷後の連続用紙3を巻き取る排紙部23を備え,図1において,テンション装置1は,インクジェットプリンタ2の給紙部20と印刷部21の間に設置されている。   The tension device 1 according to the present embodiment is a device installed in the ink jet printer 2 in order to apply tension to the continuous paper 3 in the ink jet printer 2. The ink jet printer 2 illustrated in FIG. 1 includes a paper feeding unit 20 that supplies continuous paper 3 to the ink jet printer 2, a printing unit 21 having a plurality of print heads, and a drying unit 22 that dries the continuous paper 3 printed by the printing unit 21. , A paper discharge unit 23 for winding the continuous paper 3 after printing is provided. In FIG. 1, the tension device 1 is installed between the paper supply unit 20 and the printing unit 21 of the inkjet printer 2.

図2(a)に図示したように,本実施形態に係るテンション装置1は,連続用紙3の上側と下側から連続用紙3を挟み込むようにエアを噴射する一対のエアノズル10を,連続用紙3の左右それぞれに配置した装置で,図2では,一対のエアノズル10それぞれにエアを供給するコンプレッサ11を図示している。   As illustrated in FIG. 2A, the tension device 1 according to the present embodiment includes a pair of air nozzles 10 that inject air from above and below the continuous paper 3 so as to sandwich the continuous paper 3. FIG. 2 shows a compressor 11 that supplies air to each of the pair of air nozzles 10.

図2(b)に図示したように,本実施形態に係るテンション装置1では,一対のエアノズル10の間を通過する連続用紙3の左右端は,一対のエアノズル10が噴射するエアによって挟み込まれる格好になり,一対のエアノズル10が噴射するエアの圧力による摩擦力が発生し,この摩擦力は搬送方向と逆方向の力になるため,連続用紙3にテンションが発生することになる。   As shown in FIG. 2B, in the tension device 1 according to the present embodiment, the left and right ends of the continuous paper 3 passing between the pair of air nozzles 10 are sandwiched by the air ejected by the pair of air nozzles 10. Thus, a frictional force is generated due to the pressure of the air ejected by the pair of air nozzles 10, and this frictional force is a force in the direction opposite to the conveying direction, so that tension is generated in the continuous paper 3.

また,本実施形態に係るテンション装置1によれば,一対のエアノズル10の間を通過する連続用紙3には上下からエアが噴射され,このエアが連続用紙3の表裏面を流れることで,連続用紙3の表裏面にある異物は吹き飛ばされるため,連続用紙3の表裏面にある異物を除去できる。   Further, according to the tension device 1 according to the present embodiment, air is sprayed from above and below on the continuous paper 3 passing between the pair of air nozzles 10, and the air flows continuously on the front and back surfaces of the continuous paper 3. Since the foreign matter on the front and back surfaces of the paper 3 is blown away, the foreign matter on the front and back surfaces of the continuous paper 3 can be removed.
