上記目的を達成するものとして、例えば図３に示したような装置は、本件出願 人の発明に係る特開昭５５−１５０３２７号「凝竹管材の製造方法」の公報に記 載されて既に知られている。 In order to achieve the above-mentioned object, for example, an apparatus as shown in FIG. 3 is already known as disclosed in Japanese Patent Application Laid-Open No. 55-150327, “Method for producing bamboo tube material”, of the applicant's invention. Has been.
【０００３】 即ち、二連式押出成型機（イ）の一つのスクリューシリンダー（ロ）に地色被 膜用合成樹脂（ハ）を、また他のスクリューシリンダー（ニ）には暗色の模様被 膜用合成樹脂（ホ）をそれぞれ押出し供給自在であるようにする一方、チャック （ヘ）を介して機内に挿入され、そのダイス口（ト）（チ）から機外に送出され る管棒状の芯材（リ）を一定間隔で瞬間的に、例えば連続して二回停止せしめる ことにより、芯材（リ）上に二山状の節部（ヌ）を隆成すると同時に、該節部（ ヌ）にのみ供給されて部分的に被着される模様被膜用合成樹脂（ホ）が後続の節 部に至る間に徐々に希釈されるようにしたものであった。 この他、上記模様被膜用合成樹脂（ホ）を連続的に押出し供給するという手段 も採られていた。That is, one screw cylinder (b) of the twin-screw extruder (b) is provided with a synthetic resin (c) for ground color film coating, and the other screw cylinders (d) are provided with a dark pattern film coating. The synthetic resin (e) is made to be extrudable and feedable, while it is inserted into the machine via the chuck (f) and is sent out from the machine through the die port (h). By temporarily stopping the material (i) at regular intervals, for example, twice in succession, a bimodal knot (nu) is raised on the core material (i) and, at the same time, the knot (nu) is formed. The synthetic resin (e) for the pattern coating, which was supplied only to the and partially adhered, was gradually diluted to reach the subsequent node. In addition to this, a means of continuously extruding and supplying the above-mentioned synthetic resin (e) for pattern coating has been adopted.
【０００４】[0004]
しかし上述した従来構造の二連押出成型機による場合は、地色被膜用の樹脂チ ャンバー（ル）と模様被膜用の樹脂チャンバー（オ）のダイス口（ト）（チ）の 口径が同一であったため、一般に少量供給を行う必要上、粘度並びに押出し圧力 の低い模様被膜用合成樹脂（ホ）の供給に当たって、それよりも粘度並びに押出 し圧力が高く保たれる地色被膜用合成樹脂（ハ）に押し負けて被着量が均一に得 られず、なお当初の目的とする天然の竹材に近い風合いの擬竹材が得難いという 不都合があった。 However, in the case of the above-described conventional twin extrusion molding machine, the diameter of the die chamber (e) of the resin chamber (e) for the background color film and the resin chamber (e) for the pattern film is the same. Therefore, in general, it is necessary to supply a small amount, and when supplying the synthetic resin for pattern coating (e) with low viscosity and extrusion pressure, the synthetic resin for ground color coating (ha However, it was difficult to obtain a pseudo-bamboo material with a texture close to that of the original natural bamboo material that was originally intended.
【０００４】[0004]
このような実情に鑑み本件考案者は、鋭意、実験改良の結果、上記模様被膜用 合成樹脂のダイス口（チ）の口径を地色被膜用合成樹脂のダイス口（ト）の口径 よりも僅かに大きくすることによって従来装置における上記課題を技術的に解消 したものである。 In consideration of such circumstances, the inventors of the present invention have made diligently and as a result of experimental improvements, the diameter of the die opening (h) of the synthetic resin for pattern coating is slightly smaller than that of the die opening of synthetic resin for ground color coating. The above problems in the conventional device have been technically solved by increasing the size.
【０００５】 即ち、二連式押出成型機の一つのスクリューシリンダーから地色被膜用合成樹 脂が連続的に押出し供給可能であり、又その前方に位置して設けられる他のスク リューシリンダーからは暗色の模様被膜用合成樹脂が連続的若しくは間歇的に押 出し供給可能であるようにする一方、チャックを介して機内に挿入される管棒状 の芯材が互いに連通するダイス口を通過可能であるようにし、該芯材を一定間隔 で瞬間的に停止させることにより、芯材に適宜な節部を隆成し、少なくとも該節 部を含む地色被膜上に模様被膜用合成樹脂を被着し得るようにした擬竹材の連続 製造装置において、上記模様被膜用合成樹脂のダイス口の口径を、地色被膜用合 成樹脂のダイス口の口径よりも僅かに大きく構成するという手段を用いた。That is, the synthetic resin for the background color film can be continuously extruded and supplied from one screw cylinder of the twin extrusion molding machine, and from the other screw cylinders located in front of the synthetic resin. The synthetic resin for the dark pattern coating can be continuously or intermittently extruded and supplied, while the tube rod-shaped core material inserted into the machine through the chuck can pass through the die ports communicating with each other. In this way, the core material can be instantaneously stopped at a constant interval to raise appropriate nodes on the core material, and the synthetic resin for the pattern coating can be applied onto the ground color coating containing at least the nodes. In such a continuous manufacturing apparatus for pseudo-bamboo material, a means of making the diameter of the die port of the synthetic resin for the pattern coating slightly larger than the diameter of the die port of the synthetic resin for the background color coating was used.
【０００６】[0006]
粘度および圧力の低い模様被膜用合成樹脂のダイス口径が粘度および圧力の高 い地色被膜用合成樹脂のダイス口径よりも大きいので、口径の小さいダイス口か ら芯材と共に送出される地色被膜用合成樹脂は、そのダイス口を通過した時点で 減圧されるため、粘度、圧力共に低い模様被膜用合成樹脂の被着が確実、且つ均 一に行えるという格別の作用を有するものである。 Since the die diameter of the synthetic resin for the pattern film with low viscosity and pressure is larger than the die diameter of the synthetic resin for the background color film with high viscosity and pressure, the background color film sent with the core material from the die port with the small diameter. The synthetic resin for use is depressurized when it passes through the die port, so that it has a special effect that the synthetic resin for pattern coating, which has low viscosity and low pressure, can be reliably and uniformly applied.
【０００７】[0007]
以下、本案装置の一実施例を図面に従って更に詳述すると、図１は本案装置に よって得られた擬竹材であって、１は例えば塩化ビニルの中空芯材、２は外周面 に被着された青または黄色の地色被膜、３は上記地色被膜上に一定間隔で隆成さ れた節部４に臨んで比較的薄く被着された暗色の模様被膜である。 An embodiment of the device of the present invention will be described in more detail below with reference to the drawings. FIG. 1 shows a pseudo-bamboo material obtained by the device of the present invention, in which 1 is a hollow core material of vinyl chloride, and 2 is an outer peripheral surface. The blue or yellow ground-color coating 3 is a dark-color pattern coating which is applied relatively thinly on the ground-color coating facing the nodes 4 raised at regular intervals.
【０００８】 尚、上記模様被膜用合成樹脂３は被着後に下層の地色被膜が僅かに透視可能な 程度の厚さと濃色とすることが好ましい。It is preferable that the pattern coating synthetic resin 3 has a thickness and a dark color such that the underlying ground color coating can be slightly seen through after being applied.
【０００９】 更に図２は本案装置の一例を示す部分断面図で、その５は前記地色被膜２と模 様被膜３を同時に得るための二連式押出成型機であって、地色被膜用のスクリュ ーシリンダー（ａ）からは地色被膜用合成樹脂２’が連続的に、又その前方に位 置して設けられる模様被膜用のスクリューシリンダー（ｂ）からは模様被膜用合 成樹脂３’が間歇的にそれぞれのダイス口（ｃ）（ｄ）を介して供給・被着され るように構成したものである。尚、同図中（ｅ）はノズルを示す。Further, FIG. 2 is a partial cross-sectional view showing an example of the device of the present invention, and 5 is a twin-type extrusion molding machine for simultaneously obtaining the background color film 2 and the pattern film 3 for the background color film. Synthetic resin 2'for the ground film is continuously provided from the screw cylinder (a) of the screw cylinder (a), and synthetic resin 3'for the pattern film is provided from the screw cylinder (b) of the pattern film provided in front of the screw cylinder (a). Are intermittently supplied and adhered through the respective die ports (c) and (d). Incidentally, (e) in the figure shows a nozzle.
【００１０】 而して、上記二種の被膜２、３を芯材１に被着すると同時に、これに一定間隔 で節部４を隆成するに当たっては、例えば押出成型機５の後方において同機内の ノズル（ｅ）を介して挿入され、上記各ダイス口（ｃ）（ｄ）を通過して一定速 度で送出される芯材１を把握又は解放自在なチャック６を装置し、該チャック６ を定期的に作動させることで芯材１の送出を瞬間的に停止させることで達成でき るのである。Thus, when the two kinds of coatings 2 and 3 are applied to the core material 1 and at the same time, the knot portions 4 are raised at regular intervals, for example, in the rear of the extrusion molding machine 5 inside the same. A chuck 6 that can grasp or release the core material 1 that is inserted through a nozzle (e) and is delivered at a constant speed through each of the die ports (c) and (d) is installed. This can be achieved by stopping the delivery of the core material 1 momentarily by operating it periodically.
【００１１】 尚、この場合、一重の節部であればチャック（６）による芯材１の停止を一回 行えばよく、また連続する二山状の節部４を形成するときは上記芯材１の停止を 連続して２度繰り返えせばよい。In this case, in the case of a single node, it is sufficient to stop the core material 1 by the chuck (6) once, and when forming a continuous bimodal node 4, the core material 1 is used. The stop of 1 should be repeated twice in a row.
【００１２】 従って、模様被膜用合成樹脂３’を上記節部に臨んでのみ被着させようとすれ ば、模様被膜用のスクリューシリンダー（ｂ）のチャンバー８ヘの開閉動作とチ ャック６の把握動作、即ち芯材の停止を連動させればよいのである。Therefore, if the synthetic resin for pattern coating 3 ′ is to be applied only to face the node, the opening / closing operation of the screw cylinder (b) for pattern coating to the chamber 8 and grasping the chuck 6 are performed. The operation, that is, the stop of the core material may be linked.
【００１３】 ところで本案装置は、上記地色被膜用のチャンバー７に通ずるダイス口（ｃ） よりも、その前方に位置する模様被膜用のチャンバー８に通ずるダイス口（ｄ） の口径を大きく保持させたことを構成上の特徴とするもので、これによって粘度 および押出圧力が高く、且つ連続的に押出される地色被膜用合成樹脂２’が、そ のダイス口（ｃ）を通過した時点で急激に解圧されるため、粘度および押出圧力 が低く、しかも間歇的に供給される場合の模様被膜用合成樹脂３’でも確実に排 出し、地色被膜上に均一に重層できるのである。By the way, in the device of the present invention, the diameter of the die port (d) communicating with the chamber 8 for the pattern coating located in front of the die port (c) communicating with the chamber 7 for the background color coating is kept large. This is because the synthetic resin 2'for the background color film, which has a high viscosity and a high extrusion pressure and is continuously extruded, passes through the die port (c). Since the pressure is rapidly released, the viscosity and the extrusion pressure are low, and even the synthetic resin 3'for the pattern coating when it is intermittently supplied can be reliably discharged and can be uniformly overlaid on the background color coating.
【００１４】 尚、図中９は必要に応じて模様被膜用のチャンバー８の間隙を調整し、該樹脂 の吐出量を加減し得るようにした調節ボルトを示す。Reference numeral 9 in the drawing denotes an adjusting bolt which is capable of adjusting the gap of the chamber 8 for the pattern coating to adjust the discharge amount of the resin, if necessary.
【００１５】 上記二つのダイス口（ｃ）と（ｄ）の口径差の大小によって模様被膜用合成樹 脂３’の被着厚が変化するから口径差が小さい場合は模様被膜用合成樹脂３’の 暗色度を多少濃くしておくのであるが、口径差が大きい場合、または連続的に押 出す場合には、該樹脂３’の暗色度を薄くしておく必要がある。更に上記ダイス 口（ｃ）及び（ｄ）の口径差を１〜２mm程度に保てば上記チャック６によって芯 材１の送出を停止した場合、この段差部即ちダイス口（ｄ）の内周面で樹脂の隆 起高さが規制されて節部４が形成されるから、予めダイス口（ｄ）の内周面に多 少先拡り状の曲面を付しておくことで、一様に揃った節部が隆成し得るものであ る。When the difference in diameter between the two die ports (c) and (d) is large or small, the deposition thickness of the synthetic resin 3'for pattern coating changes, so when the difference in diameter is small, the synthetic resin 3'for pattern coating is small. The dark chromaticity of the resin 3'is made slightly darker. However, when the aperture difference is large or when the resin is continuously extruded, it is necessary to make the dark chromaticity of the resin 3'thin. Further, if the diameter difference between the die ports (c) and (d) is kept at about 1 to 2 mm, when the feeding of the core 1 is stopped by the chuck 6, the stepped portion, that is, the inner peripheral surface of the die port (d). Since the protrusion height of the resin is regulated by and the node 4 is formed, it is possible to make the inner peripheral surface of the die opening (d) to have a plurality of divergent curved surfaces in order to make it uniform. The knots that are aligned can grow.
【００１６】[0016]
以上述べたところから既に明らかであるように、本考案の擬竹材の連続成型装 置によれば、従来被着が不正確または不均一であった模様被膜用合成樹脂を、そ の節部に確実且つ均一に被着することを可能ならしめたものであるから、その模 様被膜用の合成樹脂を節部のみに間歇的に供給するときは、その後の芯材の送出 に伴って該模様被膜用の合成樹脂は、後続の節部に向かって漸時暗色度が希釈さ れて天然の竹材により一層酷似した風合いを有する擬竹材が、歩留まりよく連続 して生産できるとう顕著な効果を齎らし得るものである。 As is clear from the above description, according to the pseudo-bamboo material continuous molding apparatus of the present invention, the synthetic resin for the pattern coating, which was conventionally inaccurate or unevenly applied, is applied to the node portion. Since it enables reliable and uniform deposition, when the synthetic resin for the model coating is intermittently supplied only to the nodes, the pattern is accompanied by the subsequent delivery of the core material. The synthetic resin used for the coating has the remarkable effect that the pseudo-bamboo material, which gradually dilutes the darkness toward the subsequent nodes and has a texture that more closely resembles that of natural bamboo, can be continuously produced with good yield. It is possible.
