【発明の属する技術分野】
本発明は、インク内蔵タイプの回転印に使用する多孔体を用いた無端印字ベルトに関するものである。
【０００２】
【従来の技術】
特開昭５４−１０３１２７や実開昭５４−１１８２１０等に開示されている連続気泡を有する多孔体を印字部に用いた無端印字ベルトからなる回転印は、自分自身にインクを内蔵できるので、使用の度にインクを付着させなくても連続して押印することができ大変有用である。従来、このような無端印字ベルトの多孔体には主にスポンジ化したゴムが用いられると共に、ゴムの強度を補完するための基材には主に綿布が用いられているが、前記多孔体を熱可塑性物質等の他の物質に変更したものはほとんど見られなかった。
それは、ポリエチレン、ポリプロピレン等の熱可塑性物質は綿布との接着性が非常に悪いので、前記無端印字ベルトに用いた場合は実用に耐えられない問題があったためと思われる。
【０００３】
【発明が解決しようとする課題】
そこで、本発明は無端印字ベルトの多孔体に熱可塑性物質を用いる場合、最も優れた基材を選定することを目的として発明されたものである。
【０００４】
【課題を解決するための手段】
熱によって収縮しないホットメルトシートを基材とし、前記ホットメルトシート上に熱可塑性多孔体からなる台座及び印字部を成型した回転印用無端印字ベルト。また、補強材の上に熱によって収縮しないホットメルトシートをのせたものを基材とし、前記ホットメルトシート上に熱可塑性多孔体からなる台座及び印字部を成型した回転印用無端印字ベルト。熱可塑性物質に少なくとも水溶性気泡形成剤を加えて混練したうえ板状に形成したシートを１００℃〜２００℃に加熱し、台座及び印字部を二段に彫刻した型に前記加熱しておいたシートをセットし、その上に熱によって収縮しないホットメルトシートからなる基材、又は、補強材の上に熱によって収縮しないホットメルトシートをのせてなる基材をのせ、更に押し板をのせて成型し、離型した後前記水溶性気泡形成剤を洗い出し、乾燥させた後シートの両端を重ね合わせて融着し、これを裁断して得られる前記記載の回転印用無端印字ベルトの製造方法。
【０００５】
【発明の実施の形態】
以下、本発明を詳細に説明する。
本発明は、ホットメルトシートを基材とし、前記ホットメルトシート上に熱可塑性多孔体からなる台座及び印字部を成型した回転印用無端印字ベルトである。
本発明に用いる基材には、５０℃〜１８０℃で融解する熱可塑性樹脂からなるホットメルトシートを用いることができる。材質としては、例えばポリエチレン、ポリプロピレン、塩化ビニルなどを用いることができるが、特に、ポリエチレンが好ましく用いられる。本発明のホットメルトシートには、無端印字ベルトの成型時の不良を防止するために、延伸性をかけずにシート化した熱によって収縮しないホットメルトシートを用いる。また、本発明のホットメルトシートには、非多孔体又は多孔体のどちらのシートでも使用することができる。非多孔体のシートを用いた場合は、無端印字ベルトの裏側からインキを供給することができないので印字部表面からインキを供給することとなり、多孔体のシートを用いた場合は、無端印字ベルトの裏側からでも印字部表面からでもインキを供給することができるようになる。
成形性・接着性・インキ浸透性の観点から本発明において特に好ましい基材は目付け１０〜３０ｇ／ｍ2、厚さ０．０５〜０．５０ｍｍ、網穴間１〜２ｍｍの格子状網目構造をもつポリエチレンのホットメルトシートである。
本発明の台座及び印字部には、熱可塑性多孔体を用いる。材質としては主に５０℃〜１８０℃で融解する熱可塑性樹脂が用いられ、例えばポリエチレン、ポリプロピレン、塩化ビニルなどを用いることができるが、特に、ポリエチレンが好ましく用いられる。本発明では、連続気泡を有する多孔体を得るために、熱可塑性樹脂に少なくとも塩化ナトリウムや塩化カルシウム等の水溶性気泡形成剤を加えて混練したものを成型した後、前記水溶性気泡形成剤を洗い出して多孔体化する。多孔体を製造する際には、水溶性気泡形成剤以外にカーボンブラックなど赤外線を吸収して発熱する発熱材微粉末を加えて混練してもよい。多孔体とするには熱可塑性樹脂に発泡剤を混ぜて連続気泡を形成する方法もあるが、均一な大きさでかつ連続した気泡を得られにくいので好ましくない。
なお、本発明では台座及び印字部を二段に彫刻した型を用いる。型はまず台座が彫刻され、台座の中に文字、記号、図形、絵柄等の印字部が彫刻されて二段に彫刻される。
【０００６】
本発明の無端印字ベルトは次のように製造する。
ポリエチレンなどの熱可塑性物質に少なくとも塩化ナトリウムや塩化カルシウム等の水溶性気泡形成剤を加え、これに必要に応じてカーボンブラックなどの発熱材微粉末等を加えて混練したうえ板状に形成したシートを１００℃〜２００℃に加熱し、台座及び印字部を二段に彫刻した型に前記加熱しておいたシートをセットし、その上に基材をのせ、更に押し板をのせて成型し、離型した後前記水溶性気泡形成剤を洗い出し、乾燥させた後シートの両端を重ね合わせて熱シール機にて熱融着し、これを裁断して製造する。
本発明では上述の通り、水溶性気泡形成剤を加えて板状に形成したシートを加熱して印字ベルトを成型する。よって、型を全く加熱しない或いは低温に保熱すればよく高温に加熱する必要がないので、型の高温度制御装置などが不必要となり製造装置を簡略化できる上、型の材質も金属以外にフェノール板など融点が２００℃以上のものであれば特に制限されることなく何でも使用できる。なお、水溶性気泡形成剤を加えて板状に成形したシートを１００℃〜２００℃に加熱するのは、当該シートをできるだけ軟化させて成型性をよくするためである。ここで、当該シートは水溶性気泡形成剤を加えてあるためと思われるが、１６０℃に加熱しても融解しない。加熱方法は、ホットプレートにのせたり、マイクロウエイブで熱したりする方法がとられ、当該シート全体を熱する方法であれば特に限定されない。
本製造方法では、水溶性気泡形成剤を洗い出した後のシートの両端を重ね合わせて熱シール機にて熱融着するが、材質がゴムのような熱硬化性樹脂でなく熱可塑性樹脂であるので、特別な接着剤は必要なく、そのまま熱融着できる利点がある。
【０００７】
また、前述の回転印用無端印字ベルトの基材を、ホットメルトシートを補強材で補強すれば、更に良好な無端印字ベルトが得られる。
補強材には、主に綿、絹、レーヨン、ナイロン、ポリエステルなどの繊維を平織りや綾織りした布を用いることができ、極微細繊維といわれる繊度１ｄ以下の合成繊維から繊度１００ｄ以上の天然繊維までを使用した様々な布を用いることができる。ホットメルトシート及び熱可塑性多孔体は、前述したものと同じものが使用でき、この際ホットメルトシートは、基材として作用するのは当然であるが、合成繊維だけでなく綿などの天然繊維とも強固に接着するので補強材と熱可塑性多孔体との接着剤としても作用する。
【０００８】
【実施例】
以下、本発明を実施例によって詳細に説明する。実施例１を図１に示す。
２は基材であって、７０℃で融解する厚さ０．２ｍｍの多孔体ポリエチレンからなるホットメルトシートを用いている。当該ホットメルトシートには、延伸性をかけずにシート化してあり熱によって収縮しないものを選択する。これによって、無端印字ベルトの成型時の不良を防止することができる。
４は台座、５は印字部であって、７０℃で融解する多孔体ポリエチレンを用いている。
次に、本実施例の製造方法について説明する。
まず、ポリエチレン樹脂に塩化ナトリウム微粉末を加えて混練し、厚さ２ｍｍの板状のシートを製造する。次に、この板状のシートをホットプレートで１４０℃に加熱する。次に、深さ１ｍｍの台座及び台座の中に深さ１ｍｍの印字部を彫刻した金型に離型剤を塗布し、この中に前記加熱した板状のシートをセットし、その上にポリエチレン多孔体で厚さ０．２ｍｍのホットメルトシートをのせ、更に押し板をのせて２００Ｋｇ／ｃｍ2の圧力をかけながら３０秒間プレス機で成 型する。その後、離型して成型後のシートを取り出す。次に、成型後のシートを温水中に浸して塩化ナトリウムを洗い出し完全に塩化ナトリウムを除去したら乾燥させる。十分に乾燥させた後、成型後のシートの両端を重ね合わせ、熱シール機にて熱融着する。こうして得られたものを所要の幅に裁断すると、台座の高さ１ｍｍ、印字部の高さ１ｍｍの無端印字ベルトが得られる。
そして、前記無端印字ベルトの基材側からインキを滴下供給し、これを公知の回転印に組み込んで使用する。
ここで、７０℃で融解するポリエチレン樹脂に塩化ナトリウム微粉末を加えて板状に成形したシートは、原因の詳細は不明だが１４０℃に加熱しても融解しない。
【０００９】
次に、実施例２を図２に示す。
２は基材であって、８０℃で融解する厚さ０．５ｍｍの多孔体ポリエチレンからなるホットメルトシートを用いている。当該ホットメルトシートには、延伸性をかけずにシート化してあり熱によって収縮しないものを選択する。これによって、無端印字ベルトの成型時の不良を防止することができる。
４は台座、５は印字部であって、８０℃で融解する多孔体ポリエチレンを用いている。
３は補強材であって、１２０番手の双糸を縦横１２０本／インチに平織りした綿布を用いている。
次に、実施例２の製造方法について説明する。
まず、ポリエチレン樹脂に塩化ナトリウム微粉末及びカーボンブラックを加えて混練し、厚さ２ｍｍの板状のシートを製造する。次に、この板状のシートをホットプレートで１４０℃に加熱する。次に、深さ１ｍｍの台座及び台座の中に深さ１ｍｍの印字部を彫刻した金型に離型剤を塗布し、この中に前記加熱した板状のシートをセットし、その上にポリエチレン多孔体で厚さ０．５ｍｍのホットメルトシートをのせ、その上に１２０番手の双糸を縦横１２０本／インチに平織りした綿布をのせ、更に押し板をのせて２００Ｋｇ／ｃｍ2の圧力をかけながら３ ０秒間プレス機で成型する。その後、離型して成型後のシートを取り出す。次に、成型後のシートを温水中に浸して塩化ナトリウムを洗い出し完全に塩化ナトリウムを除去できたら乾燥させる。十分に乾燥させた後、成型後のシートの両端を重ね合わせ、熱シール機にて熱融着する。こうして得られたものを所要の幅に裁断すると、台座の高さ１ｍｍ、印字部の高さ１ｍｍの無端印字ベルトが得られる。 そして、各々の印字部に印字部表面から異なるインキを滴下供給し、これを公知の回転印に組み込んで使用する。
ここで、ホットメルトシートは基材として作用するのは当然であるが、綿布とも強固に接着するので、補強材と熱可塑性多孔体との接着剤としても作用する。
【００１０】
【効果】
本発明は、回転印用無端印字ベルトの台座や印字部に熱可塑性物質を用いる場合、基材としてホットメルトシートを選択したので、長期間使用しても台座が剥離することなく十分に実用に耐えることのできる無端印字ベルトを得ることができた。
また、本発明では水溶性気泡形成剤を加えて板状に形成したシートを加熱して無端印字ベルトを製造するため、型を成型温度まで加熱する必要がなく、高価な温度制御装置などが不必要となり製造装置を簡略化できる上、型自体も融点が２００℃以上の材質のものであれば特に制限されることなく使用できる。
本製造方法では、水溶性気泡形成剤を洗い出した後のシートの両端を重ね合わせて熱シール機にて熱融着するが、材質が熱可塑性樹脂であるので特別な接着剤は必要なくそのまま熱融着できる利点がある。

[0002]
[Prior art]
Rotary stamp made of an endless printing belt using a porous material to the printing section having an open cell disclosed in JP-A-54-103127 and real HirakiAkira 54-118210 etc., the ink can be built to itself, using In this case, the ink can be continuously stamped without attaching ink, which is very useful. Conventionally, spongy rubber is mainly used for the porous body of such an endless printing belt, and a cotton cloth is mainly used as a base material for complementing the strength of the rubber. Almost no changes were made to other substances such as thermoplastics.
This is presumably because thermoplastic substances such as polyethylene and polypropylene have a very poor adhesion to cotton cloth, and therefore, when used for the endless printing belt, there is a problem that cannot be put into practical use.
[0003]
[Problems to be solved by the invention]
Therefore, the present invention was invented for the purpose of selecting the most excellent substrate when a thermoplastic material is used for the porous body of the endless printing belt.

[0005]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail.
The present invention is an endless printing belt for rotary stamping, in which a hot melt sheet is used as a base material, and a base made of a thermoplastic porous body and a printing part are molded on the hot melt sheet.
As the base material used in the present invention, a hot melt sheet made of a thermoplastic resin that melts at 50 ° C. to 180 ° C. can be used. As the material, for example, polyethylene, polypropylene, vinyl chloride and the like can be used, and in particular, polyethylene is preferably used. As the hot melt sheet of the present invention, a hot melt sheet that does not shrink due to heat formed into a sheet without applying stretchability is used in order to prevent defects during molding of an endless print belt. The hot melt sheet of the present invention can be either a non-porous material or a porous material. When a non-porous sheet is used, ink cannot be supplied from the back side of the endless printing belt, so the ink is supplied from the surface of the printing unit. When a porous sheet is used, the endless printing belt Ink can be supplied from the back side or from the surface of the printing unit.
From the viewpoints of moldability, adhesiveness, and ink permeability, a particularly preferred substrate in the present invention has a lattice network structure having a basis weight of 10 to 30 g / m 2 , a thickness of 0.05 to 0.50 mm, and a distance between mesh holes of 1 to 2 mm. It is a polyethylene hot melt sheet.
A thermoplastic porous body is used for the pedestal and printing portion of the present invention. As a material, a thermoplastic resin that melts mainly at 50 ° C. to 180 ° C. is used. For example, polyethylene, polypropylene, vinyl chloride, and the like can be used, and in particular, polyethylene is preferably used. In the present invention, in order to obtain a porous body having open cells, after molding a kneaded material obtained by adding at least a water-soluble cell forming agent such as sodium chloride or calcium chloride to a thermoplastic resin, the water-soluble cell forming agent is added. Wash out and make it porous. When producing the porous body, in addition to the water-soluble bubble forming agent, a heating material fine powder that absorbs infrared rays and generates heat, such as carbon black, may be added and kneaded. In order to obtain a porous body, there is a method in which a foaming agent is mixed with a thermoplastic resin to form open cells, but this is not preferable because it is difficult to obtain continuous cells having a uniform size.
In the present invention, a mold in which the base and the printing part are engraved in two steps is used. The mold is first engraved with a pedestal, and the printed portion of characters, symbols, figures, patterns, etc. is engraved in the pedestal and engraved in two steps.
[0006]
The endless printing belt of the present invention is manufactured as follows.
A sheet formed into a plate after kneading by adding at least a water-soluble foaming agent such as sodium chloride or calcium chloride to a thermoplastic material such as polyethylene, and adding fine powder of a heating material such as carbon black as necessary. Is heated to 100 ° C. to 200 ° C., the heated sheet is set in a mold in which the pedestal and the printing part are engraved in two steps, a base material is placed thereon, and a pressing plate is further placed on the mold, After the mold release, the water-soluble foam-forming agent is washed out and dried, and then both ends of the sheet are overlapped and heat-sealed with a heat sealing machine, and this is cut and manufactured.
In the present invention, as described above, a sheet formed into a plate shape by adding a water-soluble bubble forming agent is heated to form a print belt. Therefore, it is sufficient that the mold is not heated at all or kept at a low temperature, and it is not necessary to heat the mold at a high temperature. Therefore, a high temperature control device for the mold is not necessary, and the manufacturing apparatus can be simplified. Anything such as a phenol plate having a melting point of 200 ° C. or higher can be used without any particular limitation. The reason why the sheet formed into a plate shape by adding the water-soluble bubble forming agent is heated to 100 ° C. to 200 ° C. is to soften the sheet as much as possible to improve the moldability. Here, although it seems that the said sheet | seat has added the water-soluble bubble formation agent, even if it heats to 160 degreeC, it does not melt | dissolve. The heating method may be a method of placing on a hot plate or heating with a microwave, and is not particularly limited as long as it is a method of heating the entire sheet.
In this manufacturing method, both ends of the sheet after washing out the water-soluble bubble forming agent are overlapped and heat-sealed by a heat sealing machine, but the material is not a thermosetting resin such as rubber but a thermoplastic resin. Therefore, no special adhesive is required and there is an advantage that it can be heat-sealed as it is.
[0007]
Further, if the base material of the endless printing belt for rotation stamp described above is reinforced with a hot melt sheet with a reinforcing material, an even better endless printing belt can be obtained.
The reinforcing material can be a fabric in which plain, twill, or other fibers such as cotton, silk, rayon, nylon, polyester, etc., can be used. From a synthetic fiber having a fineness of 1d or less, called a very fine fiber, to a natural fiber having a fineness of 100d or more. Various fabrics using up to can be used. The same hot melt sheet and thermoplastic porous material as those described above can be used. In this case, the hot melt sheet naturally acts as a base material, but not only synthetic fibers but also natural fibers such as cotton. Since it adheres firmly, it also acts as an adhesive between the reinforcing material and the thermoplastic porous body.
[0008]
【Example】
Hereinafter, the present invention will be described in detail by way of examples. Example 1 is shown in FIG.
Next, the manufacturing method of a present Example is demonstrated.
First, a sodium chloride fine powder is added to a polyethylene resin and kneaded to produce a plate-like sheet having a thickness of 2 mm. Next, this plate-like sheet is heated to 140 ° C. with a hot plate. Next, a release agent is applied to a pedestal having a depth of 1 mm and a mold engraved with a printing portion having a depth of 1 mm in the pedestal, and the heated plate-like sheet is set therein, on which polyethylene is placed. A hot melt sheet having a thickness of 0.2 mm is placed on the porous body, and further a pressing plate is placed thereon, and molding is performed with a press for 30 seconds while applying a pressure of 200 kg / cm 2 . Then, it molds and takes out the sheet | seat after shaping | molding. Next, the molded sheet is immersed in warm water to wash out sodium chloride, and after the sodium chloride is completely removed, it is dried. After sufficiently drying, both ends of the molded sheet are overlapped and heat-sealed with a heat sealing machine. When the product thus obtained is cut into a required width, an endless printing belt having a pedestal height of 1 mm and a printing portion height of 1 mm is obtained.
And ink is dripped and supplied from the base material side of the endless print belt, and this is incorporated into a known rotation mark and used.
Here, the sheet formed by adding sodium chloride fine powder to polyethylene resin that melts at 70 ° C. to form a plate does not melt even when heated to 140 ° C., although the details of the cause are unknown.
[0009]
Next, Example 2 is shown in FIG.
2 is a base material, and a hot melt sheet made of porous polyethylene having a thickness of 0.5 mm that melts at 80 ° C. is used. As the hot melt sheet, a sheet that is made into a sheet without being stretched and does not shrink by heat is selected. As a result, it is possible to prevent defects during molding of the endless print belt.
Next, the manufacturing method of Example 2 is demonstrated.
First, a sodium chloride fine powder and carbon black are added to a polyethylene resin and kneaded to produce a plate-like sheet having a thickness of 2 mm. Next, this plate-like sheet is heated to 140 ° C. with a hot plate. Next, a release agent is applied to a pedestal having a depth of 1 mm and a mold engraved with a printing portion having a depth of 1 mm in the pedestal, and the heated plate-like sheet is set therein, on which polyethylene is placed. Place a hot melt sheet with a thickness of 0.5mm on a porous body, place a cotton cloth with plain weave of 120 yarns of length / width 120 / inch on top of it, place a push plate, and apply a pressure of 200Kg / cm 2 While using a press for 30 seconds. Then, it molds and takes out the sheet | seat after shaping | molding. Next, the molded sheet is immersed in warm water to wash out sodium chloride, and when it is completely removed, it is dried. After sufficiently drying, both ends of the molded sheet are overlapped and heat-sealed with a heat sealing machine. When the product thus obtained is cut into a required width, an endless printing belt having a pedestal height of 1 mm and a printing portion height of 1 mm is obtained. Then, different inks are dropped and supplied from the surface of the printing unit to each printing unit, and this is incorporated into a known rotation mark and used.
Here, it is natural that the hot melt sheet acts as a base material, but also acts as an adhesive between the reinforcing material and the thermoplastic porous body because it adheres firmly to the cotton cloth.
[0010]
【effect】
In the present invention, when a thermoplastic material is used for the base of the endless printing belt for rotating marks and the printing part, a hot melt sheet is selected as the base material, so that the base is sufficiently practical without peeling even after long-term use. An endless printing belt that can withstand was obtained.
In the present invention, an endless print belt is produced by heating a sheet formed into a plate shape by adding a water-soluble bubble forming agent. Therefore, it is not necessary to heat the mold to the molding temperature, and there is no need for an expensive temperature control device. The manufacturing apparatus can be simplified and the mold itself can be used without any particular limitation as long as it has a melting point of 200 ° C. or higher.
In this manufacturing method, both ends of the sheet after washing out the water-soluble foam-forming agent are overlapped and heat-sealed with a heat sealing machine, but since the material is a thermoplastic resin, no special adhesive is required and heat is applied as it is. There is an advantage that it can be fused.
