DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a method for producing a foamed mat, and more particularly to a method for making a layer of a foamed mat. [Prior Art] According to the fact, the EVA foam is mostly in the form of a sheet, and is cut into a mat according to the use, and the surface of these EVA mats is often covered with an ink pattern or color. .
而一般常見的EVA地墊上色製法，如第3圖所示，其 主要將發泡成形的一 EVA地墊8 1以熱滾筒8 2輥壓轉印 膜8 3 ’而使轉印膜8 3上的油墨圖案或花色8 4附著於 此EVA地墊8 1之表面8 1 1。 然而以上述方式進行轉印動作前’需先清洗EVA地墊 81表面811以讓轉印油墨具有較佳之附著效果，並由 於轉印膜8 3係以印刷機印製而成，因此還需花費印刷機 之開版費用，且轉印膜於製作時，其調色或套色對版過程 中’不可避免的將有油墨浪費之情形發生，而導致轉印膜 83之製作成本高；再者’轉印卫作者又需預製及庫存轉 印膜8 3 ’因此並不適用於少量且特殊的發泡地墊之上色 =程曰經轉印工作後所產生之職廢料僅相當浪 費，且亦會對環境造成污染。 =著π繼續參閱第4圖，係為另一種EVA地墊表面之 上法其主要係於—金屬滾筒9 1之表面上凹刻（或 凸設）形成有所需之版面圖案，再於該金屬滾輪9丄之版 201014693 面沾附有預定量之油墨9 2，並使金屬滚輪9 1版面上之 油墨9 2印至一與其相接觸之橡膠滚輪9 3的表面上，而 後再將該橡膠滾輪9 3上之油墨9 2以滾壓方式，將油墨 9 2印刷至EVA地墊9 4表面9 5上形成圖案或花色9 6 ° 惟，上述利用滾輪滾壓以印製圖案或花色之方式，雖 可省略掉轉印膜製作成本之需求，然而由於金屬滚筒9 1 參之造價係相當高昂，且同樣需要開版之費用，因此若僅要 製造少量且具有特殊花色的發泡地塾時，就必須不斷更換 適合的金屬滾筒9 1，不僅相當麻煩之外，更會使EVA地 塾上色製程之成本大幅增加。 再者’於印刷過程中為使圖案可順利附著於eva地墊 上，因此其用以與EVA地墊9 4相互接觸之橡膠滚輪9 3 係會對EVA地墊9 4產生一下壓力，藉以使橡膠滾輪9 3 上之油墨9 2得順利被印製並附著於eva地墊9 4表面9 ©- 5上而形成所需之圖案或花色9 6 ;然而由於EVA地墊9 4係為軟性材質，因此當橡膠滾輪9 3對eva地墊9 4之 表面9 5進行滾壓動作時將勢必造成EVA地墊9 4產生變 形而有被拉伸之情形發生，如此一來，將會導致腿地整 9 4預设之尺寸產生誤差，而會造成另段套色作業時有對 位不準，以及後段裁切加工時之誤差 =W進行另段之套色作業時，由於該腿地LV4A 會再受橡膠滾輪9 3m再讀拉伸，意即，當所 之套色步釋越多時’其累積誤差也會越大，因此以滾筒 6 201014693 滾壓之上色方式並無法達到精準套色之要求，而不適用於 圖形或色彩變化性較大之eVA地墊上色製程。 又，不論製作轉印膜或直接以滾筒印刷發泡地墊，在 油墨調製（調色）過程中或多或少都會造成油墨之浪費， 且印刷器具於使用過後也都必須以化學溶劑進行清洗，而 將會對環境造成嚴重污染。 因此有鑑於上述之諸項缺失，故本案發明人乃經過不 斷之苦思及试作後’才終於有本發明之產生。 【發明内容】 本發明目的之一，在於解決上述的問題而提供一種發 泡墊製作圖層之方法，其係利用噴墨機喷墨方式於發泡墊 上製出具有預疋版面圖樣，因此可省略印刷版面之開版費 用，進而達到降低製作成本之功效。 本發明目的之二，在於提供一種發泡墊製作圖層之方 法，其係可運用至少量且具有特殊花色的發泡墊製作上， 9 不需額外開版而相當符合經濟效益，且藉由喷墨方式所製 成之圖樣更具有色彩變化大、套色精準之優點。 為達前述之目的，本發明係提供一種發泡墊製作圖層 之方法，其包含有以下步驟： a. 提供一發泡墊； b. 於發泡整表層塗佈有一樹脂層； c. 以噴墨機喷墨方式於發泡墊之樹脂層上製出一具 有預定圖樣之油墨層。 而本發明之上述及其他目的與優點，不難從下述所選 201014693 用實施例之詳細說明與附圖中，獲得深入了解。 當然，本發明在某些另件上，或另件之安排上容許有 所不同，但所選用之實施例，則於本說明書中，予以詳細 說明，並於附圖中展示其構造。 【實施方式】 請參閱第1圖，圖中所示者為本發明所選用之實施例 結構，此僅供說明之用，在專利申請上並不受此種結構之 限制。 本實施例所提供之一種發泡墊製作圖層之方法，其主 要包含有以下步驟： a ·提供一發泡墊1 1，其中該發泡墊1 1係於一發 泡模具（圖中未示）中發泡成形，並形成有呈平 整狀之發泡墊表層1 2。 b ·於發泡墊1 1表層1 2上塗佈有一樹脂層1 4， 且該樹脂層1 4係可與該發泡墊1 1表層1 2相 ❹ 互緊密接合。 c ·以喷墨機2 1喷墨方式於發泡墊1 1之樹脂層1 4上噴射有預定油墨2 2，而該噴墨機係可供輸 入一預定圖樣，以使該喷墨機2 1所喷射出之油 墨2 2得藉以製成該預定圖樣，且該樹脂層1 4 係與該油墨2 2間具有良佳之相容性而藉以使該 樹脂層1 4上可形成有該預定圖樣之油墨層2 d ·接著，依照所需之尺寸及形狀對發泡墊1 1進行 201014693 裁切動作，即可得表層12具有預定圖層之發泡 墊材。 且由於該發泡材料於發泡成型時’其表層1 2上將會 自然形成有多數孔洞，因此當於該發泡塾11表層12樹 脂塗佈有該樹脂層14時，該樹脂層14係可滲透於各孔 洞中，以使該樹脂層14得與該發泡墊1 1表層1 2相互 緊密接合。 當然，本發明之發泡墊1 1於發泡成形時，亦可製成 ® 具有紋路之表層12，如第2圖所示，其係為本發明之第 二實施例，其與上述實施例之差異係在於，該發泡墊1 1 係具有呈紋路狀之表層1 2，並於該發泡墊1 1之紋路狀 表層1 2上係塗佈有該樹脂層1 4，而後即可利用該喷墨 機2 1於該發泡墊1 1之樹脂層1 4上直接進行喷墨，並 藉以使具有紋路狀表層1 2之發泡墊1 1，同樣可藉由喷 墨機2 1喷墨方式而製成表層1 2具有預定圖樣之型態 參者，且由於本發明係以喷墨機2 1喷射油墨2 2之方式於 該發泡墊1 1上製成油墨層2 3，因此即使該發泡墊1 1 之表層12係具有呈紋路狀之表層1 2，該油墨2 2係仍 可確實塗附，而具有不易剝離脫落之特點。 然於此必須特別提出說明的是，當發泡塾1 1於發泡 模具中發泡成形後係可自其厚度中線進行剖切，而使該發 泡塾11表層係至少形成有一呈非平整狀之裁切面，且當 以該裁切面為喷墨基準面時，係同樣先於該裁切面丄上塗 佈有該樹脂層14 ’而後再利用該喷墨機2 1於該發泡整 201014693 Ο 1 1之樹脂層；I 11之裁切面製=直接進行喷墨，而同樣可使該發泡塾 战具有預定圖樣之型態者。而本發明發泡 方法係可產生有以下優點： ,明以噴墨機喷墨方式製作發泡墊圖層之方法 用不必花費凹凸版之開版費用以及轉印膠膜之費 • 而可有效降低發泡墊製作圖層時之成本。 ，明以噴墨機喷墨方式製作發泡墊圖層之方法 上係可運用至少量且具有特殊花色的發泡墊製作 不又基本量之限制，並可少量生產。 2明藉由噴墨方式所製成之圖樣更具有色彩變 .本，大以及套色精準之優點。 月可免除習用印刷油墨於調色過程所造成之 Li浪費，以及免除印刷器具於使用後需以牝拳 音洗所造成之浪費及污染。 ，發明以喷墨機喷墨方式製作發泡墊圖層之方涑 製不需自行調色、不需清洗機台，而可大幅縮鱗 程時間’並有效節省人力以及有效節省資游。 的瑞詳細說明，可使熟知本項技藝者明瞭本發明 達成前述目的，實已符合專利法之規定，爰提出專 2 3 4 5 201014693 【圖式簡單說明】 第1圖係本發明第一實施例之製法流程示意圖 第2圖係本發明第二實施例之製法流程示意圖 第3圖係習用EVA地墊利用轉印膜上色之流程示意圖 第4圖係另一種習用EVA地整上色製程之結構示意圖 【主要元件符號說明】 (習用部分） φ EVA地墊8 1、9 4 熱滾筒8 2 表面8 1 1、9 5 轉印膜8 3 油墨圖案8 4、9 6 (本發明部分） 發泡墊11 表層12 樹脂層14 喷墨機21 油墨2 2 油墨層2 3 參.The conventional EVA floor mat coloring method, as shown in FIG. 3, mainly applies a foam-formed EVA floor mat 8 1 to a transfer film 8 3 ' by a heat roller 8 2 to transfer the film 8 3 The upper ink pattern or color 8 4 is attached to the surface 8 1 1 of the EVA mat 8 1 . However, before the transfer operation in the above manner, the surface 811 of the EVA floor mat 81 needs to be cleaned first to allow the transfer ink to have a better adhesion effect, and since the transfer film 83 is printed on a printing machine, it is also costly. The printing plate is costly, and when the transfer film is produced, the inevitable waste of ink will occur during the process of color matching or color registration, which results in high production cost of the transfer film 83; The transfer wei author also needs prefabrication and stock transfer film 8 3 'Therefore, it is not suitable for the coloring of a small amount of special foam mats. The waste generated by the transfer after the transfer work is only quite wasteful, and also It will pollute the environment. Continuing to refer to Fig. 4, on the surface of another EVA floor mat, the main surface of the metal roller 9 1 is indented (or convexly formed) to form a desired layout pattern, and then The metal roller 9丄201014693 is coated with a predetermined amount of ink 9 2, and the ink 9 2 on the surface of the metal roller 9 1 is printed on the surface of a rubber roller 9 3 which is in contact with it, and then the rubber is applied. The ink 9 2 on the roller 9 3 is printed on the surface of the EVA mat 94 by a rolling method to form a pattern or a color of 9 6 °. However, the above-mentioned roller is pressed to print a pattern or a color. Although the cost of the transfer film production can be omitted, the cost of the metal roll 9 1 is quite high, and the cost of opening the plate is also required. Therefore, if only a small amount of foamed mantle having a special color is to be produced, It is necessary to constantly replace the suitable metal drum 911, which is not only quite troublesome, but also greatly increases the cost of the EVA mantle coloring process. In addition, in order to make the pattern adhere smoothly to the eva floor mat during the printing process, the rubber roller 9 3 for contacting the EVA mat 94 has a pressure on the EVA mat 94, thereby making the rubber The ink 9 2 on the roller 9 3 is smoothly printed and attached to the surface 9 of the eva mat 9 4 to form a desired pattern or color 9 6; however, since the EVA mat 94 is a soft material, Therefore, when the rubber roller 9 3 rolls the surface 9 5 of the eva floor mat 94, it will inevitably cause the EVA mat 94 to be deformed and stretched, which will result in the leg being finished. 9 4 The size of the preset produces an error, which will cause misalignment during the other part of the coloring operation, and the error during the subsequent cutting process = W. When the other part of the coloring operation is performed, the LV4A will be rubber again. The roller 9 3m is read and stretched again, that is, the more the cumulative step of the color is, the larger the cumulative error will be. Therefore, the rolling method of the roller 6 201014693 cannot meet the requirements of accurate color registration, instead of Applicable to eVA mat coloring process with large graphics or color variability. Moreover, regardless of the transfer film or the direct printing of the foamed floor mat, the ink is more or less wasteful during the ink preparation (toning) process, and the printing instrument must be cleaned with a chemical solvent after use. It will cause serious pollution to the environment. Therefore, in view of the above-mentioned lack of items, the inventor of the present invention finally has the invention after continuous arduous thinking and trial. SUMMARY OF THE INVENTION One object of the present invention is to solve the above problems and provide a method for fabricating a layer of a foaming pad, which is formed by using an inkjet inkjet method on a foaming pad to have a pre-cut layout, and thus can be omitted. The cost of the opening of the printed layout, in turn, can reduce the cost of production. The second object of the present invention is to provide a method for making a layer of a foaming pad, which can be produced by using a foaming pad of at least a quantity and having a special color, 9 which is economically advantageous without additional opening, and by spraying The pattern made by the ink method has the advantages of large color change and precise color registration. For the purpose of the foregoing, the present invention provides a method for making a layer of a foaming pad comprising the steps of: a. providing a foaming pad; b. applying a resin layer to the foamed surface layer; c. The ink jetting method produces an ink layer having a predetermined pattern on the resin layer of the foaming pad. The above and other objects and advantages of the present invention will be readily understood from the following detailed description of the embodiments and the accompanying drawings. Of course, the invention may be varied on certain components, or in the arrangement of the components, but the selected embodiments are described in detail in the specification and their construction is shown in the drawings. [Embodiment] Please refer to Fig. 1, which shows the structure of the embodiment selected for the present invention, which is for illustrative purposes only and is not limited by this structure in the patent application. The method for producing a layer of a foaming pad provided in this embodiment mainly comprises the following steps: a) providing a foaming mat 1 1 , wherein the foaming mat 1 1 is attached to a foaming mold (not shown) The foam is formed by foaming, and a foamed surface layer 12 of a flat shape is formed. b. A resin layer 14 is coated on the surface layer 1 of the foaming mat 1 1 , and the resin layer 14 is in close contact with the surface layer 12 of the foaming mat 1 1 . c) a predetermined ink 2 2 is ejected onto the resin layer 14 of the foaming mat 1 1 by an ink jet ejecting method, and the ink jet machine is adapted to input a predetermined pattern to make the ink jet 2 The ink 2 2 is ejected to form the predetermined pattern, and the resin layer 14 has good compatibility with the ink 2 2 so that the predetermined pattern can be formed on the resin layer 14 Ink layer 2 d. Next, the foaming mat 1 1 is subjected to a 201014693 cutting operation in accordance with the required size and shape to obtain a foamed mat having a predetermined layer of the surface layer 12. Further, since the foamed material is formed with a large number of pores on the surface layer 1 at the time of foam molding, when the resin layer 14 is resin-coated on the surface layer 12 of the foamed enamel 11, the resin layer 14 is It is permeable to each of the holes such that the resin layer 14 is in close contact with the surface layer 12 of the foamed mat 1 1 . Of course, the foaming mat 11 of the present invention can also be made into a textured surface layer 12 when foamed, as shown in FIG. 2, which is a second embodiment of the present invention, which is the same as the above embodiment. The difference is that the foamed mat 1 1 has a textured surface layer 1 2 , and the resin layer 14 is coated on the textured surface layer 1 2 of the foamed mat 1 1 and can be utilized. The ink jet machine 2 1 directly ejects ink on the resin layer 14 of the foaming mat 1 1 , so that the foaming mat 1 1 having the textured surface layer 12 can also be sprayed by the ink jet machine 2 1 . In the ink mode, the surface layer 12 has a pattern of a predetermined pattern, and since the ink jet machine 2 1 ejects the ink 2 2 to form the ink layer 2 3 on the foaming mat 1 1 , Even if the surface layer 12 of the foamed mat 1 1 has a textured surface layer 12, the ink 2 2 can be surely applied and has a characteristic that it is not easily peeled off. However, it must be particularly noted that when the foamed crucible 11 is foamed and formed in the foaming mold, it can be cut from the thickness of the center line, and the foamed crucible 11 has at least one non-formed surface layer. a flattened cut surface, and when the cut surface is an ink jet reference surface, the resin layer 14' is also applied to the cut surface 而 before the ink jet machine 2 1 is used for the foaming 201014693 树脂 1 1 resin layer; I 11 cutting surface system = direct inkjet, but also the foaming warfare type with a predetermined pattern. The foaming method of the present invention can produce the following advantages: The method for producing the foaming mat layer by the ink jet ink jet method can effectively reduce the cost of the opening of the embossing plate and the cost of the transfer film. The cost of making a layer on a foam pad. The method of making a foaming pad layer by inkjet inkjet method can be made by using a foaming pad of at least a quantity and having a special flower color, and can be produced in a small amount. 2 The pattern made by the inkjet method has more color change. The advantages of this, large and precise color registration. The month can eliminate the waste of Li caused by the printing ink in the process of coloring, and eliminate the waste and pollution caused by the washing of the printing equipment after the use of the punching machine. Invented by the inkjet inkjet method to make the foaming mat layer, the system does not need to be self-toning, no need to clean the machine, but can greatly reduce the scale time' and save manpower and save money.
