Description

【０００１】
【発明の属する技術分野】
本発明は、インクジェット記録装置、さらに詳細には、インクジェット記録装置の印字ヘッドに関する。
【０００２】
【従来の技術】
インクジェット記録装置の印字ヘッドは生産ラインに組み込み使用される。
【０００３】
インクジェット記録装置は、装置本体からの電気信号を印字ヘッドに伝える電線ならびにインク・溶剤の流路を収納した接続ケーブルを、印字ヘッドのベース板に取り付け、装置本体と印字ヘッド間を結び、印字ヘッドのみを生産ラインに組み込んでいた。
【０００４】
【発明が解決しようとする課題】
前述したように、インクジェット記録装置は生産ラインに組み込み使用される。
【０００５】
そして、生産ラインの配置替えによって設置スペースが限られることがあり、前記接続ケーブルが印字ヘッドベース板の長手方向に取り付けられている印字ヘッドでは、接続ケーブルの引出し方向を変えようとした場合、接続ケーブルの外周を覆う保護被覆の最小屈曲半径には制限があるため、生産ラインに組み込めなくなるケースも出てくる可能性がある。
【０００６】
本発明の課題は、限られた狭い設置スペースにも組み込み可能な印字ヘッドを備えたインクジェット記録装置を提供することにある。
【０００７】
【課題を解決するための手段】
前記課題は、インク粒子により記録を行うインクジェット記録装置において、装置本体からの電気信号を印字ヘッドに伝える電線ならびにインク・溶剤の流路を収納した接続ケーブルの引き出し方向を変更する手段を備えることによって達成される。
【０００８】
【発明の実施の形態】
以下、本発明の実施例を図１、図２に基づいて説明する。
【０００９】
図１は印字ヘッド１００の構成をモデル図的に示すもので、ベース板１上にノズル２、帯電電極３、偏向電極４、ガター５が設置され、印字ヘッド１００の側面には、装置本体からの電気信号を印字ヘッド１００に伝える電線ならびにインク・溶剤の流路を収納した接続ケーブル１２を通過させるための中空形状をなす雄ネジ６が設けられている。
【００１０】
雄ネジ６には、角型平板状の第１の接続フランジ１０を印字ヘッド１００の側面に取り付けるナット１１がネジ止めされている。すなわち、接続ケーブル１２を貫通させた印字ヘッド１００の側面には、この接続ケーブル１２の外周を覆う保護被覆１３の印字ヘッド１００側を装着する第１の接続フランジ１０が取り付けられている。保護被覆１３の印字ヘッド１００側端部には、前記第１の接続フランジ１０にネジ止めされる第２の接続フランジ１４が取り付けられている。第１および第２の接続フランジ１０、１４の平板部には、接続ケーブル１２を印字ヘッドベース板１の長手方向と同方向に引き出す場合に、前記両フランジ１０、１４をネジ止めする同一ピッチのネジ穴９、１５がそれぞれ設けられている。第１、第２の接続フランジ１０、１４の平板側面には、接続ケーブル１２の取付方向が変わった場合に、前記両フランジ１０、１４をネジ止めする同一ピッチのネジ穴７、１７がそれぞれ設けられている。
【００１１】
これにより、接続ケーブル１２の引出し方向が従来と同様、印字ヘッドベース板１の長手方向と同方向に引き出された印字ヘッド１００が形成される。
【００１２】
図２に接続ケーブル１２の引出し方向を変更する場合を示す。
【００１３】
雄ネジ１６を外し、第２の接続フランジ１４を第１の接続フランジ１０から取り外す。次に、第１、第２の接続フランジ１０、１４の平板側面に設けた同一ピッチのネジ穴７、１７に対し、雄ネジ１６をネジ止めして前記両フランジ１０、１４を取り付ける。なお、この状態では、第１、第２の接続フランジ１０、１４間において、接続ケーブル１２の保護被覆１３がなく、接続ケーブル１２は外から受ける衝撃によって傷、折れ、曲がり等の不具合を生じる場合のあり得ることを予め予想しておくのがよい。そこで、第１、第２の接続フランジ１０、１４間において、接続ケーブル１２の保護として、ケーブル通過用の溝を形成した保護ブロック１８を第２の接続フランジ１４に取り付ける。具体的には、第２の接続フランジ１４、保護ブロック１８に設けた同一ピッチのネジ穴１５、１９に対し、雄ネジ２０をネジ止めして第２の接続フランジ１４と保護ブロック１８を取り付ける。
【００１４】
【発明の効果】
本発明によれば、第１の接続フランジの平板側面に接続ケーブルの引き出し方向を印字ヘッド長手方向に対し交差する方向に変更する場合に、第２の接続フランジを第１の接続フランジの側面にネジ止めする同一ピッチのネジ穴を設けたことにより、限られた印字ヘッドの設置スペースに対し、装置本体からの電気信号を印字ヘッドに伝える電線ならびにインク・溶剤の流路を収納した接続ケーブルの引出し方向を、印字ヘッドベース板の長手方向と交差する方向に変更可能として、狭い設置スペースにも組み込み可能な印字ヘッドを備えたインクジェット記録装置を提供することができる。
また、保護被覆でカバーできない接続ケーブル屈曲部を保護ブロックで保護することにより、接続ケーブルの衝撃による傷、折れ、曲がり等の不具合を防止することができる。
【図面の簡単な説明】
【図１】本発明の一実施例に係るプリントヘッドの構成モデル図である。
【図２】図１の状態において、接続ケーブルの引出し方向を印字ヘッド長手方向軸心から直角方向に変更する場合の説明図である。

BACKGROUND OF THE INVENTION
The present invention relates to an ink jet recording apparatus, and more particularly to a print head of an ink jet recording apparatus.
[0002]
[Prior art]
The print head of the ink jet recording apparatus is used in a production line.
[0003]
Inkjet recording devices are attached to the base plate of the print head by connecting an electrical cable that transmits an electrical signal from the device main body to the print head and a flow path for ink and solvent, and the print head is connected to the print head. Only incorporated into the production line.
[0004]
[Problems to be solved by the invention]
As described above, the ink jet recording apparatus is incorporated and used in a production line.
[0005]
And the installation space may be limited due to the rearrangement of the production line. In the print head in which the connection cable is attached in the longitudinal direction of the print head base plate, if the connection cable is pulled out, the connection direction is Since the minimum bend radius of the protective coating covering the outer periphery of the cable is limited, there may be cases where it cannot be incorporated into the production line.
[0006]
An object of the present invention is to provide an ink jet recording apparatus provided with a print head that can be incorporated into a limited installation space.
[0007]
[Means for Solving the Problems]
In the ink jet recording apparatus that performs recording with ink particles, the above-mentioned problem is provided with means for changing the drawing direction of a connection cable containing an electric wire and an ink / solvent flow path that transmits an electric signal from the apparatus main body to the print head. Achieved.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to FIGS.
[0009]
FIG. 1 shows the configuration of the print head 100 as a model diagram. A nozzle 2, a charging electrode 3, a deflection electrode 4 and a gutter 5 are installed on a base plate 1, and a side surface of the print head 100 is mounted from the main body of the apparatus. A male screw 6 having a hollow shape is provided for passing an electric signal for transmitting the electrical signal to the print head 100 and a connection cable 12 containing a flow path for ink and solvent.
[0010]
The male screw 6 is screwed with a nut 11 for attaching the first connecting flange 10 having a square plate shape to the side surface of the print head 100. In other words, the first connection flange 10 for mounting the print head 100 side of the protective coating 13 covering the outer periphery of the connection cable 12 is attached to the side surface of the print head 100 through which the connection cable 12 has passed. A second connection flange 14 that is screwed to the first connection flange 10 is attached to the end portion of the protective coating 13 on the print head 100 side. The flat portions of the first and second connection flanges 10 and 14 have the same pitch for screwing the flanges 10 and 14 when the connection cable 12 is pulled out in the same direction as the longitudinal direction of the print head base plate 1. Screw holes 9 and 15 are provided, respectively. The flat plate side surfaces of the first and second connection flanges 10 and 14 are respectively provided with screw holes 7 and 17 having the same pitch for screwing the flanges 10 and 14 when the mounting direction of the connection cable 12 is changed. It has been.
[0011]
Thus, the print head 100 is formed in which the connection cable 12 is drawn in the same direction as the longitudinal direction of the print head base plate 1 as in the conventional case.
[0012]
FIG. 2 shows a case where the drawing direction of the connection cable 12 is changed.
[0013]
The male screw 16 is removed, and the second connection flange 14 is removed from the first connection flange 10. Next, both the flanges 10 and 14 are attached by screwing male screws 16 into the screw holes 7 and 17 having the same pitch provided in the flat plate side surfaces of the first and second connection flanges 10 and 14. In this state, there is no protective coating 13 for the connection cable 12 between the first and second connection flanges 10 and 14, and the connection cable 12 may suffer from defects such as scratches, breaks, and bends due to external impacts. It is better to predict in advance that this is possible. Therefore, a protection block 18 in which a cable passage groove is formed is attached to the second connection flange 14 between the first and second connection flanges 10 and 14 as protection of the connection cable 12. Specifically, the second connection flange 14 and the protection block 18 are attached by screwing the male screw 20 into the screw holes 15 and 19 having the same pitch provided in the second connection flange 14 and the protection block 18.
[0014]
【The invention's effect】
According to the present invention, when the connection cable pulling direction is changed to the direction intersecting the longitudinal direction of the print head on the flat plate side surface of the first connection flange, the second connection flange is changed to the side surface of the first connection flange. By providing screw holes with the same pitch to be screwed in, the connection cable that houses the electric wires and ink / solvent flow paths that transmit electrical signals from the main unit to the print head in a limited print head installation space. It is possible to provide an ink jet recording apparatus including a print head that can be incorporated in a narrow installation space by allowing the drawing direction to be changed in a direction intersecting with the longitudinal direction of the print head base plate.
Further, by protecting the connection cable bent portion that cannot be covered with the protective coating with the protection block, it is possible to prevent defects such as scratches, breaks, and bending due to the impact of the connection cable.
