Description
本発明は、被処理物のドラム回転式染色機の脱水方法及び脱水装置に関するものである。 The present invention relates to a dewatering method and a dewatering device for a drum rotary dyeing machine for processing objects.
ここで、被処理物とは、ポリエステル、ポリエステルの混紡及び交織品等の合成繊維や、合成皮革、綿、レーヨン及び麻等のセルローズ系繊維、及びこれらセルローズ系繊維を含む混紡品等を含める。 Here, the object to be treated includes synthetic fibers such as polyester, polyester blended and woven products, cellulose fibers such as synthetic leather, cotton, rayon and hemp, and blended products including these cellulose fibers.
従来のドラム回転式染色機の脱水方法及び脱水装置にあっては、被処理物を脱水する時、ドラムの回転を一方向とされていた。このため、被処理物がドラムの外周方向に移動し、遠心力で押さえつけられ位置が変わりにくく、ドラムの内周部に位置する被処理物と外周部に位置する被処理物との水分率に差が生じていた。 In the conventional dewatering method and dewatering apparatus of the drum rotary dyeing machine, when the workpiece is dewatered, the drum is rotated in one direction. For this reason, the object to be processed moves in the outer peripheral direction of the drum, is pressed by centrifugal force, and the position is not easily changed, and the moisture content between the object to be processed located on the inner periphery of the drum and the object to be processed located on the outer periphery is There was a difference.
また、ドラムが回転している間、ドラムの外周に押さえつけられた被処理物は、ほぼ同じ形状のままで脱水されるため、被処理物が折れて密度の高い部分と低い部分とができ、水分率に差が生じていた。
従来のドラム回転式染色機では、被処理物の水分率に差が生じて、水分率の高い被染物に合わせて乾燥時間を設定しなければならないことから、脱水工程後の乾燥時間が長くなってしまう問題点があった。本発明において、これらの問題点を解決することを目的とする。 In conventional drum rotary dyeing machines, there is a difference in the moisture content of the material to be treated, and the drying time must be set according to the material to be dyed with a high moisture content. There was a problem. An object of the present invention is to solve these problems.
そこで、本発明においては、脱水工程において、被処理物の水分率を均一にする様に脱水し、全体としての水分率を低下させることができるものである。 Therefore, in the present invention, in the dehydration step, dehydration is performed so that the moisture content of the object to be processed is uniform, and the overall moisture content can be reduced.
上記目的を達成するため、本発明の第1発明として、外胴内に水平軸を中心に回転可能に設けた内胴としてのドラムに、被染物などの被処理物を装填して回転駆動することにより脱水処理をするドラム回転式染色機における脱水方法において、ドラムの回転方向を正転し、停止させ、正転又は逆転の再回転し、停止させ、被処理物の内周、外周又は折れ位置に変動をきたす工程を繰り返し、被処理物の平均水分率を低下させるドラム回転式染色機における被処理物の脱水方法とした。 In order to achieve the above object, as a first invention of the present invention, a drum as an inner cylinder provided rotatably around a horizontal axis in an outer cylinder is loaded with an object to be processed such as an object to be rotated. In a dewatering method in a drum rotary dyeing machine that performs dewatering treatment, the drum rotation direction is rotated forward and stopped, the forward rotation or reverse rotation is rotated and stopped, and the inner periphery, outer periphery, or fold of the object to be processed is stopped. The process of varying the position was repeated, and a dewatering method for the object to be processed in the drum rotary dyeing machine for reducing the average moisture content of the object to be processed was obtained.
また、第2発明として、ドラム内の被処理物の脱水方法として、脱水工程の全体を約18分(20分程度)として、正転又は逆転の回転時間を3分間隔毎に停止を6回程度組み入れて、順次、被処理物の内周、外周又は折れ位置に変動をきたすような工程を設け、被処理物の平均水分率を低下させるドラム回転式染色機における被処理物の脱水方法とした。 Further, as a second invention, as a method for dewatering the workpiece in the drum, the entire dewatering step is about 18 minutes (about 20 minutes), and the rotation time of normal rotation or reverse rotation is stopped 6 times every 3 minutes. A dewatering method for the object to be processed in a drum rotary dyeing machine, in which steps are taken to change the inner circumference, outer periphery or folding position of the object to be processed in order to reduce the average moisture content of the object to be processed. did.
更に、第3発明として、外胴内に水平軸を中心に回転可能に設けた内胴としてのドラムに、被染物などの被処理物を装填して回転駆動することにより脱水処理をするドラム回転式染色機において、被処理物をドラム内に設けた突起物に引つ掛かるようにしてドラムの回転に連動させ、ドラムを正転、停止、正転又は逆転の再回転、停止するように駆動モータを制御し、被処理物の位置を変動させて平均水分率を低下させることを特徴とするドラム回転式染色機における被処理物の脱水装置とした。
Further, as a third invention, a drum rotation for performing a dehydration process by loading an object to be processed such as an object to be dyed into an inner cylinder rotatably provided around a horizontal axis in the outer cylinder and rotationally driving the drum. In a type dyeing machine, the object to be processed is hooked on a protrusion provided in the drum and linked with the rotation of the drum, and the drum is driven to rotate forward, stop, forward or reverse rotation , and stop. A dewatering device for an object to be processed in a drum rotary dyeing machine is characterized in that the motor is controlled to change the position of the object to be processed to lower the average moisture content.
本発明の脱水方法及び脱水装置を用いることで、被染物の脱水率が向上し、被処理物の全体の水分率を低下させ、その後の乾燥工程の時間短縮を図れるようになった。 By using the dehydrating method and the dehydrating apparatus of the present invention, the dehydration rate of the object to be dyed is improved, the total moisture content of the object to be processed is reduced, and the time for the subsequent drying process can be shortened.
本発明の脱水方法及び脱水装置に用いられる被処理物の形状としては、人工皮革等の不織布関係、布帛、ニット、製品(ガーメント)等の全ての形状、形態に対応できる。 The shape of the object to be processed used in the dehydration method and dehydration apparatus of the present invention can correspond to all shapes and forms of non-woven fabrics such as artificial leather, fabrics, knits, products (garment) and the like.
また、脱水処理時の形態としては、ドラム回転式のもの特に、丸タンク式のドラム染色機で、ドラムが回転し、布帛、製品を処理する形態をしているものが含まれる。
さらに、脱水処理の目的の範囲としては、ドラムを回転させる機械を使用して、前処理、染色、脱水を目的とする処理全般を含むものとする。
In addition, the form during the dehydration process includes a drum rotating type, particularly a round tank type drum dyeing machine, in which the drum rotates to process fabrics and products.
Furthermore, the scope of the purpose of the dehydration process includes all processes for the purpose of pretreatment, dyeing, and dehydration using a machine that rotates a drum.
本発明のドラム回転式染色機の構造を図1及び図2に示す。 The structure of the drum rotary dyeing machine of the present invention is shown in FIGS.
図1及び図2において、1は染色槽、2はドラムで、染色槽1の外胴内に設けられ、水平軸を中心に回転可能に設けられている。3は軸受けで、軸4を支える。5は駆動モータで、ドラム2を正転、停止、再回転(逆転を含む。)、また、間欠運転することができるよう制御される。ドラムの回転速度は、駆動モータにより調整でき、回転方向も任意に変えることができる。ドラムを再回転させる場合、正転、逆転のいずれも可能である。
1 and 2,
6は突起部で、ドラム2内に設けられ、被処理物がドラムの回転に沿うようになっている。
図3は脱水回転中における被処理物7の状態を示している。被処理物7は、ドラム回転による遠心力を受けて、ドラムの外周に押し付けられ、突起部6に引っ掛かる状態にある。ドラムの回転によって、被処理物7中の水分が脱水されることとなる。
FIG. 3 shows the state of the
図4は、ドラムを一旦停止した時における被処理物8の状態を示す図である。被処理物8は、重力の影響を受けて下方に崩れ、再回転させた時には被処理物の位置関係が変わることとなる。
FIG. 4 is a diagram illustrating a state of the
停止時間は、3秒であり、5回停止した場合であっても、5X3秒=15秒で全行程の18分に比べて短時間となる。したがって、停止時間が全行程の時間に与える影響はほとんどない。 The stop time is 3 seconds, and even if it is stopped 5 times, 5 × 3 seconds = 15 seconds, which is shorter than 18 minutes of the entire stroke. Therefore, the stop time has almost no influence on the entire process time.
ここで、本発明の脱水処理方法及び脱水装置の実施例を示す。まず、比較対象例として、ドラムの回転状態を連続して18分間正転した場合の脱水後の平均水分率、最大水分率、最小水分率の結果を下記に示す。 Here, the Example of the dehydration processing method and dehydration apparatus of this invention is shown. First, as an example for comparison, the results of the average moisture content, maximum moisture content, and minimum moisture content after dehydration when the rotating state of the drum is continuously rotated forward for 18 minutes are shown below.
ここで、被処理物として、肌着63g/枚を23枚、及び、ストッキング63g/枚を26枚投入した。ドラムの全容量は、3.1kgであり、脱水ドラムの大きさは、内径φ600mmX直胴部400mm、脱水回転数は250rpmとした。
次に、本発明の実施例1として、「正転を3分間した後に停止する」工程を6回繰り返した場合の脱水後の平均水分率、最大水分率、最小水分率の結果を下記に示す。
この実施例1の脱水時間と比較対象例の連続脱水する時間とは共に18分間であり同一時間である。 The dehydration time in Example 1 and the continuous dehydration time in the comparative example are both 18 minutes and the same time.
しかし、実施例1では「停止」工程を入れたことにより、被処理物が重力の影響で下方に移動し、脱水条件の悪かったドラムの内周の被処理物がその位置を変えることになる。これが繰返されることにより、どの被処理物の脱水条件も均一となり、公平に脱水されることとなる。その結果、脱水後最小水分率は変わりがないが、最大水分率が下がり、全体としての水分率が低下する効果を得ることができた。 However, in the first embodiment, since the “stop” step is included, the workpiece is moved downward due to the influence of gravity , and the workpiece on the inner periphery of the drum whose dehydration condition is bad changes its position. . By repeating this, the dewatering conditions of all the objects to be processed become uniform, and the water is dehydrated fairly. As a result, the minimum moisture content after dehydration was not changed, but the maximum moisture content was lowered, and the effect of lowering the moisture content as a whole could be obtained.
次に、実施例2として、「正転3分後停止する」「その後逆回転3分後、停止する」工程を繰り返した場合の脱水後の平均水分率、最大水分率、最小水分率の結果を下記に示す。
この実施例2では、脱水工程での回転方向を正転を停止した後、逆回転としていることにより、ドラムの内周の被処理物が逆回転のし始めにその位置を変えることにより、よりよく脱水されることがわかる。
実施例1の場合と、ほぼ同様の効果が得られた。
In the second embodiment, the rotation direction in the dehydration step is changed to the reverse rotation after stopping the normal rotation, so that the workpiece on the inner periphery of the drum changes its position at the start of the reverse rotation, It turns out that it dehydrates well.
The same effect as in the case of Example 1 was obtained.
ドラム回転式染色機の脱水を一旦止め、内部の被染物の内周、外周位置、及び折れ位置を変え、再度脱水することで、被処理物の脱水状態を均一にすることができる。脱水後、乾燥工程に移る場合にあっても時間の短縮が図れるようになった。 By temporarily stopping the dehydration of the drum rotary dyeing machine, changing the inner circumference, the outer circumference position, and the folding position of the internal dyed object and dehydrating again, the dehydrated state of the object to be treated can be made uniform. After dehydration, the time can be shortened even when moving to the drying process.
