Description

本発明は、押印装置の昇降動作に連動してキャップが回動し、印字体を露出する押印装置に関するものである。   The present invention relates to a stamping device in which a cap rotates in conjunction with an ascending / descending operation of the stamping device to expose a printed body.

従来より、昇降動作に連動して印面の保護または印面の気密を確保しているキャップを回動させる構成の出願は多く存在しており、例えば、実公昭58−11584号、特開平9−104156号、特開平11−58911号などが公知となっている。
実公昭58−11584号の印判は、押印したいところに印判を置き、上方より押圧力を印判自体に加えるものである。そうすると、印面が降下し、突子5と長窓孔6により印字面カバー9が横に開閉し印面が露出し、押印できるものである。この印判は、気密性を必要とする印判ではないので、印字面カバーの下方に設けられた底蓋部8と印面の距離(空間)が大きいものとなっている。また、この空間を大きくすると押圧力で軸回動する際に、長窓孔6の形状を規制する必要がなく、比較的自由に設計を行なえるものである。したがって、実公昭58−11584号公報の第1図、第2図に見られるように、長窓孔6は直線に近い形状を有している。
特開平9−104156号や特開平11−58911号の印字装置は、速乾性インキを含浸したインキパッドを往復駆動させるものであって、気密性を有する構成をとるが、回転半径が大きくなりがちであって、装置全体が大きくなる不具合があった。
Conventionally, there have been many applications for a structure in which a cap that protects the seal face or seals the seal face in conjunction with the lifting operation is rotated. For example, Japanese Utility Model Publication No. 58-11484, Japanese Patent Laid-Open No. 9-104156. No. 1, JP-A-11-58911, and the like are known.
The stamp of Japanese Utility Model Publication No. 58-11584 places a stamp where it is desired to be stamped, and applies a pressing force to the stamp itself from above. Then, the marking surface is lowered, and the printing surface cover 9 is opened and closed laterally by the protrusion 5 and the long window hole 6 so that the marking surface is exposed and can be stamped. Since this stamp is not a seal that requires airtightness, the distance (space) between the bottom cover portion 8 provided below the print surface cover and the stamp surface is large. Further, when this space is enlarged, it is not necessary to regulate the shape of the long window hole 6 when the shaft is rotated by the pressing force, and the design can be performed relatively freely. Therefore, as shown in FIGS. 1 and 2 of Japanese Utility Model Publication No. 58-11584, the long window hole 6 has a shape close to a straight line.
The printing devices disclosed in Japanese Patent Laid-Open Nos. 9-104156 and 11-58911 reciprocate an ink pad impregnated with quick-drying ink and have an airtight structure, but the radius of rotation tends to be large. However, there is a problem that the entire apparatus becomes large.

そこで、本出願人は、特開2004−284301号を提案し、印面キャップ等の印面を覆う部材に気密保持機能を設け、押印動作と共に印面に当接している印面を覆う部材を回転させ、気密保持及び解除を自由に行うことができる押印装置を提供した。   Therefore, the present applicant has proposed Japanese Patent Application Laid-Open No. 2004-284301, and provided a hermetic holding function for a member covering the marking surface such as a marking cap and rotating the member covering the marking surface in contact with the marking surface together with the stamping operation. A stamping device that can be freely held and released is provided.

実公昭58−11584号公報Japanese Utility Model Publication No. 58-11484 特開平9−104156号公報JP-A-9-104156 特開平11−58911号公報JP-A-11-58911 特開2004−284301号公報JP 2004-284301 A

しかしながら、特開2004−284301号の押印装置は、印面サイズを大きくすると、印面乾燥防止用の印面気密部との接触範囲が大きくなり、印面キャップ開閉時に摩擦による負荷が過大となって、スムーズな開閉動作が不可能となる欠点があった。
また、印面サイズを大きくすると、印面気密部の場所々々によってパッキンの密着力の相違が発生し、気密性が悪化する欠点があった。
そこで本発明は、印面サイズが大きくてもスムーズな開閉と高い気密性を併せ持った押印装置を提供することを目的とする。
However, in the stamping device disclosed in Japanese Patent Application Laid-Open No. 2004-284301, when the printing surface size is increased, the contact range with the sealing surface airtight portion for preventing drying of the printing surface is increased, and the load due to friction is excessive when the printing surface cap is opened and closed. There was a drawback that the opening and closing operation was impossible.
In addition, when the size of the marking surface is increased, there is a drawback that a difference in the adhesion of the packing occurs depending on the location of the sealing surface hermetic portion and the airtightness deteriorates.
Accordingly, an object of the present invention is to provide a stamping device having both smooth opening and closing and high airtightness even when the stamping surface size is large.

In the present invention, the bottom portion of the cap portion, which is a substantially plate-like body, is pivotally attached to the side surface of the cap portion so that the rotation direction is in a free state, thereby reducing a friction load applied when the cap portion and the bottom portion are opened and closed. In addition, the cap portion can be opened and closed smoothly.
In addition, since the load is evenly applied to all the bottom portions of the cap portion, a difference in adhesion does not occur, and the cap portion can be reliably opened and closed without rattling.
Furthermore, since loads are equally applied to all the bottom portions of the cap portion, high airtightness can be ensured when an airtight packing is provided on the bottom portion of the cap portion. Therefore, in this case, a printing body made of a porous printing material having continuous pores containing volatile ink can be used, and a stamping device capable of continuous stamping can be provided.
In addition, since the load is evenly applied to all parts of the bottom of the cap part, when an ink pad that can contact the printed body is provided at the bottom of the cap part, the ink of the ink pad should be uniformly transferred to the printed body. Therefore, it is possible to provide a stamping device capable of continuous stamping that can obtain a clear imprint.

ここで、底部14には必要に応じて気密を確保する為のパッキン15を設けることができる。前記パッキン15は、印字体11の印面周縁を覆い隠すように設けられており、前記突起12が前記誘導孔9の最上部に位置する時は、印字体保持部10の下端面と底部14のパッキン15が当接して印面の気密が確保される。パッキン15は、揮発性インキに侵されない材質が好ましく、例えばシリコーンゴム、フッ素ゴム、EPDM等が使用可能である。
Reference numeral 5 denotes a cap portion, which is provided with one or more arm portions 13 on the side surface and a bottom portion 14 on the lower end. The arm portion 13 of the present embodiment is a plate-like member and has a guide hole 9 on its side surface. The guide hole 9 is engaged with the projection 12 of the stamping body 7.
The guide hole 9 of this embodiment is composed of two types of straight lines, a refracted straight line A and a straight line B. The straight line A has an inclination of 30 degrees with respect to the horizontal plane when the vertical plane with respect to the center line of the stamping device is a horizontal plane with the cap portion 5 being closed (base state) as a reference. Yes. The straight line B has an inclination of 45 degrees with respect to the horizontal plane so as to be continuous with the straight line A. Furthermore, the intersection of the straight line A and the straight line B is on the center line of the stamping device. In the present embodiment, the center line is the same as the center line of the stamp portion 6 and the printing body 11. If the center line is different in the other embodiments, the straight line A and the straight line B are provided in accordance with the center line of the stamp portion 6. The straight line B is provided so as to be movable downward from the lowest point of the cap portion 5 in the open state until the printing surface of the printing body 11 is sufficiently exposed.
The guide hole 9 is composed of two types of refracted straight lines, but may not necessarily be two types of refracted straight lines, but may be a circular hole, a curved hole, or a straight hole.
The arm portion 13 is pivotally attached to at least one of the stamping portion guides 21 with the cap rotation shaft 8 so that the cap portion 5 can be rotated with the cap rotation shaft 8. The cap rotating shaft 8 is installed at a location above the guide hole 9 and away from the center line.
The bottom portion 14 is a substantially plate-like body, and is pivotally attached to a lower end of the side surface of the cap portion, that is, a lower end of the arm portion 13 with a bottom portion rotating shaft 22.
Here, a packing 15 for ensuring airtightness can be provided on the bottom 14 as necessary. The packing 15 is provided so as to cover the periphery of the printing surface of the printing body 11, and when the protrusion 12 is positioned at the uppermost portion of the guide hole 9, the lower end surface of the printing body holding portion 10 and the bottom portion 14 are provided. The packing 15 comes into contact with the seal surface to ensure airtightness. The packing 15 is preferably made of a material that is not affected by volatile ink. For example, silicone rubber, fluorine rubber, EPDM, or the like can be used.

次に、本実施例の作動方法について説明する。
図3は基本状態である。この時、エアーシリンダースプリング19は、エアーシリンダースプリングストッパー20とエアーシリンダー2の有底部の両端に当接しており、エアーシリンダースプリングストッパー20を上方に弾発させ、押印部6を上方に位置させる。その際、押印部6の押印部本体7外面に設けた突起12は、屈折した2種類の直線のうち上方側の直線Aの最上位に位置することになり、キャップ部5を上方に引き上げることとなる。これによって、キャップ部の腕部13の下端に設けた底部14が、印字体11を覆い隠し、キャップ部5が閉口した状態となる。
ここで、本実施例の底部14にはパッキン15が設けてあり、当該パッキン15は印字体11の印面周縁を覆い隠すように設けられており、基底状態の時は印字体保持部10の下端面と前記パッキン15が当接して印面の気密が確保される。特に、閉口した状態の時、底部14及びパッキン15は押印部スプリング16を若干上方に押圧するので、押印部スプリング16が反発して印字体保持部を押し返そうとし、相乗効果によって気密密閉効果が増大する。
Next, the operation method of the present embodiment will be described.
FIG. 3 shows a basic state. At this time, the air cylinder spring 19 is in contact with both ends of the air cylinder spring stopper 20 and the bottomed portion of the air cylinder 2, and the air cylinder spring stopper 20 is ejected upward, and the stamping portion 6 is positioned upward. At that time, the protrusion 12 provided on the outer surface of the stamping portion main body 7 of the stamping portion 6 is positioned at the top of the upper straight line A of the two refracted straight lines, and pulls the cap portion 5 upward. It becomes. As a result, the bottom portion 14 provided at the lower end of the arm portion 13 of the cap portion covers and hides the print body 11 and the cap portion 5 is closed.
Here, a packing 15 is provided on the bottom 14 of this embodiment, and the packing 15 is provided so as to cover the periphery of the printing surface of the printing body 11. The end surface and the packing 15 are in contact with each other, and the seal surface is airtight. In particular, when the mouth is closed, the bottom portion 14 and the packing 15 press the stamping portion spring 16 slightly upward, so that the stamping portion spring 16 repels and pushes back the print body holding portion. Will increase.

図4は突起12が直線Aと直線Bの交点に位置している状態の中間状態である。基底状態からエアーシリンダー2に空気が注入されると、押圧棒17がエアーシリンダースプリング19の弾発力に抗して下方に押しやられる。すると前記押圧棒17の下方には押印部6が設けられているため、前記押圧棒17の動きと同時に押印部6が下方に降りる。すると誘導孔9の直線A最上位に位置していた突起12は、押印部6の動きに合わせて直線Aに沿って動く。するとキャップ部5が下方に押しやられ、キャップ回転軸を中心にキャップ部5が回動し、印字体保持部10とキャップ部5の閉口が解除され、印字体が露出する。
この時、キャップ部側面の腕部13の下端には、略板状体としたキャップ部の底部14を底部回転軸22をもって回動自在に軸着してあるので、底部14はフリーに回動可能となり、前述したキャップ回転軸を中心にキャップ部5が回動する際には、それと同時に底部14も回動し、キャップ部及び底部にかかる摩擦負荷を軽減することができると共に、キャップ部のスムーズで円滑な開口が可能となる。
また、底部14自体が回動するので、キャップ部5を過大に回動させなくても印字体11の印面を露出させることができ、押印装置全体の可動必要範囲を小さくすることができる。よって、他の生産設備に設置した場合に過大な可動スペースを要求せず、コンパクトな生産設備組み立てに寄与できる。
更に、キャップ部の底部の全箇所に均等に負荷がかかるので、キャップ部の底部に気密用パッキンを設けた場合は、高い気密性を確保することができる。よって、この場合は、揮発性インキを含有させた連続気孔を有する多孔性印材からなる印字体を使用することができ、連続押印可能な押印装置を提供することができる。
FIG. 4 shows an intermediate state in which the protrusion 12 is located at the intersection of the straight line A and the straight line B. FIG. When air is injected into the air cylinder 2 from the ground state, the pressing rod 17 is pushed downward against the elastic force of the air cylinder spring 19. Then, since the stamping portion 6 is provided below the pressing rod 17, the stamping portion 6 descends simultaneously with the movement of the pressing rod 17. Then, the projection 12 positioned at the top of the straight line A of the guide hole 9 moves along the straight line A in accordance with the movement of the stamp portion 6. Then, the cap unit 5 is pushed downward, the cap unit 5 rotates around the cap rotation axis, the closing of the print body holding unit 10 and the cap unit 5 is released, and the print body is exposed.
At this time, the bottom portion 14 of the cap portion which is a substantially plate-like body is pivotally attached to the lower end of the arm portion 13 on the side surface of the cap portion with a bottom rotation shaft 22 so that the bottom portion 14 rotates freely. When the cap portion 5 rotates about the cap rotation axis described above, the bottom portion 14 also rotates at the same time, so that the frictional load applied to the cap portion and the bottom portion can be reduced, and the cap portion A smooth and smooth opening is possible.
Further, since the bottom portion 14 itself rotates, the marking surface of the printing body 11 can be exposed without excessively rotating the cap portion 5, and the required movable range of the entire stamping device can be reduced. Therefore, when installing in other production facilities, an excessive movable space is not required, and it can contribute to compact production facility assembly.
Furthermore, since loads are equally applied to all the bottom portions of the cap portion, high airtightness can be ensured when an airtight packing is provided on the bottom portion of the cap portion. Therefore, in this case, a printing body made of a porous printing material having continuous pores containing volatile ink can be used, and a stamping device capable of continuous stamping can be provided.

図5は押印状態であって押印部6の最下点位置である。この時、キャップ部5の最下点位置よりも更に印字体11の印面が最下点位置となっており、紙等の押印物に押印可能な状態である。
エアーシリンダースプリング19は最大の圧縮状態であり、また、押印部本体7に設けた突起12は、誘導孔9の直線Bの最下点に位置しており、この位置で押印可能となる。
押印されると押印物に厚さ、傾き、凹凸がある場合は、押印部スプリング16がこれらを吸収し、鮮明な押印が得られる。
FIG. 5 shows the stamped state and the lowest point position of the stamped portion 6. At this time, the marking surface of the printing body 11 is further at the lowest point position than the lowest point position of the cap portion 5, and is capable of being stamped on a stamped object such as paper.
The air cylinder spring 19 is in the maximum compressed state, and the protrusion 12 provided on the stamp portion main body 7 is located at the lowest point of the straight line B of the guide hole 9 and can be stamped at this position.
When the stamped object has a thickness, inclination, and unevenness, the stamped part spring 16 absorbs the stamped object and a clear stamp is obtained.

押印後は、エアーシリンダー2のエアーを抜くとエアーシリンダースプリングストッパー20がエアーシリンダースプリング19の復元力で元の位置に戻っていく。すると前記エアーシリンダースプリング19の復元力は、押印部6及びキャップ部5に作用し、前記押印部6を元に引き上げながらキャップ部5を回動させ、併せて底部14も元の状態の位置に戻っていき、中間状態から基底状態へ逆の行程を進んで再び印字体11を閉口する。   After the stamping, the air cylinder spring stopper 20 returns to the original position by the restoring force of the air cylinder spring 19 when the air cylinder 2 is evacuated. Then, the restoring force of the air cylinder spring 19 acts on the stamp portion 6 and the cap portion 5, and the cap portion 5 is rotated while pulling up the stamp portion 6, and the bottom portion 14 is also returned to the original position. The printer 11 returns and proceeds in the reverse process from the intermediate state to the ground state to close the print body 11 again.

本実施例は以上のような構成であるので、上記記載の効果以外にも、無駄な動きをすることなしに、迅速に、最短で押印可能な状態を得られる効果がある。また、本実施例は押印装置として、容易に機械等に取り付けることができる利点がある。   Since the present embodiment is configured as described above, in addition to the effects described above, there is an effect that it is possible to obtain a state that can be imprinted quickly and in the shortest without making useless movement. Further, this embodiment has an advantage that it can be easily attached to a machine or the like as a stamping device.

図6は実施例2の中間状態であって、実施例2はキャップ部の底部に基底状態で印字体と当接可能なインキパッドを設けた押印装置である。
構成は、実施例1の底部14に更にインキパッド23を追加した構成となっており、作動方法も実施例1と同様である。唯一の相違点は、基底状態から押印状態を経てまた基底状態に戻る度に、印字体はインキパッド23からインキの供給を受ける点にある。
本実施例は、キャップ部の底部の全箇所に均等に負荷がかかるので、印字体に均一にインキパッドのインキを転写させることができ、鮮明な印影が得られる連続押印可能な押印装置を提供することができ、更に、キャップ部の底部の全箇所に均等に負荷がかかるので、キャップ部の底部に気密用パッキンを設けた場合は、高い気密性を確保することができ、揮発性インキを含有させたインキパッドを使用した連続押印可能な押印装置を提供することができる。
FIG. 6 shows an intermediate state of the second embodiment. The second embodiment is an imprinting device in which an ink pad that can be brought into contact with the printing body in the base state is provided at the bottom of the cap portion.
The configuration is such that an ink pad 23 is further added to the bottom 14 of the first embodiment, and the operation method is the same as that of the first embodiment. The only difference is that the printing medium receives ink supply from the ink pad 23 each time it returns from the ground state to the stamped state and back to the ground state.
This embodiment provides a stamping device capable of continuous stamping that can uniformly transfer the ink of the ink pad to the printing body and obtain a clear imprint because the load is evenly applied to all the bottom portions of the cap portion. Furthermore, since the load is evenly applied to all the bottom part of the cap part, when an airtight packing is provided on the bottom part of the cap part, high airtightness can be ensured, and volatile ink can be used. A stamping device capable of continuous stamping using the contained ink pad can be provided.
