Abstract

<P>PROBLEM TO BE SOLVED: To improve a dehydration rate without making the compression pressure of a dehydrator excessive by improving the dehydrator 2 cooperatively operating with a consecutive washing machine 1 and a dryer 4 so as to maximize the dehydration time by the dehydrator 2 without troubling the other cooperative apparatuses. <P>SOLUTION: The consecutive washing machine 1 originates a washing finish noticing and dehydration operation stoppage command signal α before the finish of a washing time. The dehydrator 2 given the command signal α stops dehydration operation and advances to discharging operation. Thus, the dehydrator 2 does not spend a stand-by time wastefully but carries out the dehydration operation for the longest period within a limit of avoiding damaging laundry articles. Similarly, the dryer 4 outputs a drying operation state display signal γ, and an automatic controller CPU gives an operation command signal β to the dehydrator 2 to stop the dehydration operation and to advance to the discharging operation. The dehydrator 2 attains a maximum dehydration rate without causing a failure in the cooperative operation with the other apparatuses and without damaging the laundry articles. <P>COPYRIGHT: (C)2006,JPO&NCIPI

(図1下半部(従来例)参照)連続洗濯機1はサイクル運転され、脱水機2から待機信号nを受け、洗濯処理した洗濯物を矢印iのように脱水機2に供給する。
該脱水機は投入信号mを受けて運転され、脱水処理した洗濯物を移送コンベア3に供給する(矢印j)。
この移送コンベア3は、受け取った洗濯物を、複数基の乾燥機4の何れかに分配して供給する(脱水機と乾燥機との処理能力のバランスが図られている)。

FIG. 1 shows a washing plant constructed by combining a continuous washing machine, a dehydrator, and a dryer. The lower part of the reference line RR is a schematic diagram of the conventional example, and the upper part of the reference line RR is the main line. It is a dehydrator control system diagram in one embodiment of the invention.
(See the lower half (conventional example) in FIG. 1) The continuous washing machine 1 is cycled, receives a standby signal n from the dehydrator 2, and supplies the laundry subjected to the washing process to the dehydrator 2 as indicated by an arrow i.
The dehydrator is operated in response to the input signal m and supplies the dehydrated laundry to the transfer conveyor 3 (arrow j).
The transfer conveyor 3 distributes and supplies the received laundry to any of the plurality of dryers 4 (a balance between the processing capabilities of the dehydrator and the dryer is achieved).
The laundry after drying is carried out by the carry-out conveyor 5 and sent to a press machine (not shown).

FIG. 3 is a time chart when the washing machine and the dehydrator are operated in cooperation with each other according to the conventional technology.
The time required for the laundry operation varies depending on the type of laundry. Therefore, the work cycle of the continuous washing machine is appropriately set according to the type of the laundry.
The arrow Tmax is the maximum value of the washing time, and the arrow Tmin is the minimum value of the washing time.
The difference between them, Tmax−Tmin = Tc, is the fluctuation range of the washing time.
One cycle time of the dehydrator is the sum of the squeezing time Ta and the laundry discharge time Tb.
Here, in the prior art, the continuous washing machine 1 is not allowed to wait for time (the dehydrator 2 waits for the laundry to be discharged)
The total time (Ta + Tb) of the squeezing time and the discharging time is set so that the washing time minimum value Tmin is substantially equal.
JP-A-8-2899994 Japanese Patent Laid-Open No. 2001-232094 JP 2001-218998 A

従来例のタイムチャート(図3)によると、搾り時間Ta+排出時間Tbが、洗濯時間最小値Tminを超えないので、連続洗濯機1に時間待ちをさせる心配が無い。
その代り、洗濯時間が最大値Tmaxの場合には、変動時間幅Tcに相当する時間だけ
今度は脱水機2が時間待ち(連続洗濯機1の洗濯作業終了を待つこと)してしまう。
According to the time chart of the conventional example (FIG. 3), the squeezing time Ta + the discharge time Tb does not exceed the washing time minimum value Tmin, so there is no fear of causing the continuous washing machine 1 to wait for time.
Instead, when the washing time is the maximum value Tmax, the dehydrator 2 waits for the time (waiting for the end of the washing operation of the continuous washing machine 1) for the time corresponding to the fluctuation time width Tc.

脱水機が時間待ちすることの技術的な意義について次に述べる。
a.脱水機の作業能率を上げるには、搾りシリンダの油圧力を上げることが考えられる。
c.しかし、搾り圧力を上げると、洗濯物を損傷させる虞れが増す(この場合、目に見え ない損耗も充分に考慮しなければならない)。
d.脱水が不充分であると、次工程である乾燥機の作業時間が伸びる。
e.こうした事情から脱水機は、余り圧力を上げないで、時間をかけて搾りたい。
しかしながら、連携作業している他の機器に迷惑を及ぼさないように、許される範囲内で最長時間を捻出して搾り作業を遂行したい……というのが、洗濯業界の要請である。
ただし、搾り時間は単純に、長ければ長いほど良いというものではなく、限度が有るから、この限度を越えない範囲内での搾り時間延長を図らねばならない。
The technical significance of the dehydrator waiting for time is described below.
a. In order to increase the working efficiency of the dehydrator, it is conceivable to increase the oil pressure of the squeezing cylinder.
c. However, increasing the squeezing pressure increases the risk of damaging the laundry (in this case, invisible wear must be fully considered).
d. If the dehydration is insufficient, the working time of the dryer, which is the next process, is extended.
e. For these reasons, the dehydrator wants to squeeze over time without increasing pressure.
However, the laundry industry demands that the squeezing work should be carried out for the longest time within the allowable range so as not to inconvenience other cooperating devices.
However, the longer the squeezing time is, the longer the squeezing time is, the better. There is a limit, so the squeezing time must be extended within a range not exceeding this limit.

本発明は上述の事情に鑑みてなされたものであって、その目的とするところは、
連続洗濯機や乾燥機と連携作動している脱水機を適用の対象とし、該連携機器の作業能率を阻害しない範囲内において、なるべく多くの脱水作業時間を捻出することによって、
洗濯物に損傷を与えることなく、充分の脱水率を得ようとするものである。
ただし、搾り時間が限度(洗濯物の種類によって異なる)を越えない範囲内に留める。
The present invention has been made in view of the above-mentioned circumstances, and the object is as follows.
By applying a dehydrator that operates in conjunction with a continuous washing machine or dryer, within the range that does not impede the work efficiency of the cooperating equipment, by deriving as much dehydration work time as possible,
It is intended to obtain a sufficient dehydration rate without damaging the laundry.
However, the squeezing time is kept within a range that does not exceed the limit (depending on the type of laundry).

この指令信号を受けた脱水機が直ちに搾り作業を停止して排出作業に移れば、排出作業が終わるころ、連続洗濯機が洗濯を終えて、洗濯処理済みの洗濯物を供給してくれる。このため、互いに待ち時間を生じない。
しかも、これらの動作が自動的に制御されるので人手を要せず、かつ、人的な誤操作を生じる虞れが無い。
According to the invention of claim 2 described above, the continuous washing machine operating in cooperation with the dehydrator sends a notice signal in consideration of the time allowance for the discharge operation of the dehydrator. This signal has the meaning of “command signal for ending the squeezing operation and shifting to the discharging operation” for the dehydrator.

しかも、この操作が自動的に制御されるので人手を要せず、かつ、人的な誤操作を生じる虞れが無い。
According to the invention of claim 3 described above, when all of the plurality of dryers operating in cooperation with the dehydrator are performing the drying operation, the dehydrator is waiting for the waiting time without waiting for the dehydrator. Since the squeezing operation can be continued, the substantial operating rate of the dehydrator can be increased to the maximum (maximum within a range that does not disturb other cooperative devices).
Moreover, since this operation is automatically controlled, no manual operation is required, and there is no possibility of causing a human erroneous operation.

請求項4に係る発明方法の構成は、脱水処理した洗濯物を複数基の乾燥機に分配供給する脱水機において、
予め、脱水機の搾り作動の時間を任意に調節できるように構成しておき、

As a result, the maximum dehydration rate can be obtained within a possible range without forcibly increasing the press pressure of the dehydrator and causing the laundry to be damaged.

請求項2の発明によると、脱水機と連携作動している連続洗濯機が、脱水機の排出作業の時間的な余裕を加味して予告信号を発信してくれる。この信号は脱水機に対する「搾り作動を終了して排出作動に移行する指令信号」という意味あいを有する。
この指令信号を受けた脱水機が直ちに搾り作業を停止して排出作業に移れば、排出作業が終わるころ、連続洗濯機が洗濯を終えて、洗濯処理済みの洗濯物を供給してくれる。このため、互いに待ち時間を生じない。
しかも、これらの動作が自動的に制御されるので人手を要せず、かつ、人的な誤操作を生じる虞れが無い。
According to the invention of claim 2, the continuous washing machine operating in cooperation with the dehydrator sends a notice signal in consideration of the time allowance for the discharge operation of the dehydrator. This signal has the meaning of “command signal for ending the squeezing operation and shifting to the discharging operation” for the dehydrator.
When the dehydrator that has received this command signal immediately stops the squeezing operation and moves to the discharging operation, the continuous washing machine finishes the washing and supplies the laundry after the discharging operation. For this reason, there is no waiting time for each other.
In addition, since these operations are automatically controlled, no manual operation is required, and there is no risk of human error.

請求項3の発明によると、脱水機と連携作動している複数基の乾燥機が総べて乾燥動作中である場合、該脱水機が漫然と手待ちすることなく、待ち時間中も搾り動作を継続できるので、脱水機の実質的な稼働率を最大限(他の連携機器に迷惑を及ぼさない範囲内で最大に)上昇させることができる。
しかも、この操作が自動的に制御されるので人手を要せず、かつ、人的な誤操作を生じる虞れが無い。
According to the invention of claim 3, when all of the plurality of dryers operating in cooperation with the dehydrator are in the drying operation, the dehydrator does not wait in a vain manner and performs the squeezing operation during the waiting time. Since it can be continued, the substantial operating rate of the dehydrator can be increased to the maximum (maximum within a range that does not disturb other linked devices).
Moreover, since this operation is automatically controlled, no manual operation is required, and there is no possibility of causing a human erroneous operation.

請求項4の発明方法によると、脱水機と連携作動している乾燥機の乾燥処理に遅れを生じても、該脱水機を漫然と待機させることなく、複数基の乾燥機の内の何れかが空くまでの間に搾り作動を続行して、被洗濯物を損傷させる虞れなく最大限の脱水率が得られる。   According to the method of the invention of claim 4, even if a delay occurs in the drying process of the dryer operating in cooperation with the dehydrator, any one of the plurality of dryers does not cause the dehydrator to stand on standby. The squeezing operation is continued until empty, and the maximum dehydration rate can be obtained without fear of damaging the laundry.

図1の参考線R−Rよりも上方に書き入れた制御系統図のように、連続洗濯機1は洗濯終了よりも一定の時間だけ早く洗濯終了予告信号αを発信する。この予告信号αは、脱水機に対する搾り作動停止指令信号という意味あいを有している。
また、複数基の乾燥機4のそれぞれは、乾燥作動中であるか否かを表す乾燥作動状態表示信号γを発信する。

As shown in the control system diagram written above the reference line RR in FIG. 1, the continuous washing machine 1 transmits a washing end notice signal α earlier than the end of washing by a certain time. This notice signal α has the meaning of a squeezing operation stop command signal for the dehydrator.
Each of the plurality of dryers 4 transmits a drying operation state display signal γ indicating whether or not the drying operation is being performed.
The automatic control device CPU receives the drying operation state display signal γ, and gives an operation command signal β to the dehydrator 2 based on the input.

図2は、本発明の1実施形態におけるタイムチャートである。
図の上半、洗濯機(1)の欄に示されている矢印Tmaxは、連続洗濯機1(図1)の洗濯時間の最大値であり、矢印Tminは同じく最小値である(図3を参照して既述)。
連続洗濯機(1)のタイムチャートについては、図3について説明した従来例と同様である。
本発明においては、脱水機2(図1)の搾り時間が可変である(排出時間Tbは、容易に変更できないので一定値(例えば30秒)である。
図の下半、脱水機(2)の欄に示されている矢印Taは脱水機2(図1)の搾り時間
最小調節値、矢印Tdは同じく最大調節値である。
これらの値は、つぎのようにして設定される。
FIG. 2 is a time chart in one embodiment of the present invention.
In the upper half of the figure, the arrow Tmax shown in the column of the washing machine (1) is the maximum value of the washing time of the continuous washing machine 1 (FIG. 1), and the arrow Tmin is also the minimum value (see FIG. 3). See above).
About the time chart of a continuous washing machine (1), it is the same as that of the prior art example demonstrated about FIG.
In the present invention, the squeezing time of the dehydrator 2 (FIG. 1) is variable (the discharge time Tb is a constant value (for example, 30 seconds) because it cannot be easily changed).
In the lower half of the figure, the arrow Ta shown in the column of the dehydrator (2) is the minimum adjustment value for the squeezing time of the dehydrator 2 (FIG. 1), and the arrow Td is the maximum adjustment value.
These values are set as follows.

図2(本発明)における脱水機の搾り時間最小調節値Taは、洗濯機の洗濯時間最小値Tminから、排出時間Tbを差し引いた値である。すなわち、従来例(図3)における脱水機の搾り時間Taと同じ値である。
その理由は、搾り時間をこれよりも短縮すれば必ず待ち時間(脱水機が待機する時間)を生じるからである。すなわち、搾り時間をこれ以上に倹約することは不合理であり、実益が無いからである。
以上に述べたことから、本実施形態における搾り時間最小調節値Taは
Ta=Tmin−Tb である。
The minimum squeezing time adjustment value Ta of the dehydrator in FIG. 2 (the present invention) is a value obtained by subtracting the discharge time Tb from the washing time minimum value Tmin of the washing machine. That is, it is the same value as the squeezing time Ta of the dehydrator in the conventional example (FIG. 3).
The reason is that if the squeezing time is shorter than this, a waiting time (time for the dehydrator to wait) is always generated. In other words, it is unreasonable to save more time for squeezing and there is no real benefit.
As described above, the minimum squeezing time adjustment value Ta in the present embodiment is Ta = Tmin−Tb.

図2(本発明)における脱水機の搾り時間最大調節値Tdは、洗濯機の洗濯時間最大値Tmaxから、排出時間Tbを差し引いた値まで延長調節可能になっている。すなわち、従来例(図3)における脱水機の搾り時間Tbに比して、洗濯時間変動幅Tc以内の調節時間幅で延長されている。
ここに、調節時間幅Te≦Tc(洗濯時間変動幅) である。
本発明における搾り時間は定数ではなく、調節可能な変数である。従って、上記の「延長されている」とは、正確には「延長し得るようになっている」ということである。
上記の延長調節可能な時間Tcが、洗濯機における洗濯時間変動幅Tcであったこと、および、搾り時間の延長は限度内に制限されることを想起すると、請求項1に記載されている次の式が導き出される。
搾り時間最大調節値Td−搾り時間最小調節値Ta≦洗濯時間変動幅Tc………(式1)
The maximum squeezing time adjustment value Td of the dehydrator in FIG. 2 (the present invention) can be extended and adjusted to a value obtained by subtracting the discharge time Tb from the maximum washing time value Tmax of the washing machine. That is, compared with the squeezing time Tb of the dehydrator in the conventional example (FIG. 3), it is extended by the adjustment time width within the washing time fluctuation width Tc.
Here, adjustment time width Te ≦ Tc (washing time fluctuation width).
The expression time in the present invention is not a constant but an adjustable variable. Therefore, the above-mentioned “extended” means precisely “can be extended”.
Recalling that the extension adjustable time Tc was the washing time variation width Tc in the washing machine and that the extension of the squeezing time is limited within limits, the following is described in claim 1 The following formula is derived.
Maximum squeezing time adjustment value Td−Minimum squeezing time adjustment value Ta ≦ Washing time fluctuation range Tc (Equation 1)

先に図1について述べた洗濯終了予告信号αは、図2のタイムチャートにおいて、洗濯終了予想時点から逆算して「脱水機の排出時間Tbだけ以前」に発信される。
従って、洗濯時間の伸縮に伴って洗濯終了予告信号αの発信時点は変化する。図2において、洗濯終了予告信号αの発信時点に(予告)αと付記した。
(図1参照)連続洗濯機1から洗濯終了予告・搾り作動停止信号αを受け取ると、脱水機2は搾り作動を終了して、排出作動に移る。
排出動作を済ませて作動サイクルを終えたとき、連続洗濯機1は次のサイクルの洗濯物を送り込んでくる。
このようにして脱水機2は、連続洗濯機1との連携関係に待ち時間を発生させることなく、可能な範囲内で、しかも洗濯物を損傷させない限度内で最長時間の搾り作動を行ない、最高脱水率を達成する。
The washing end notice signal α described above with reference to FIG. 1 is transmitted “before the dehydrator discharge time Tb” in the time chart of FIG.
Therefore, the transmission end point of the washing end notice signal α changes with expansion / contraction of the washing time. In FIG. 2, (notice) α is added when the washing end notice signal α is transmitted.
(See FIG. 1) When the washing end notice / squeezing operation stop signal α is received from the continuous washing machine 1, the dehydrator 2 ends the squeezing operation and proceeds to the discharging operation.
When the discharge cycle is completed and the operation cycle is completed, the continuous washing machine 1 feeds the laundry of the next cycle.
In this way, the dehydrator 2 performs the squeezing operation for the longest time within a possible range without causing a waiting time in the cooperative relationship with the continuous washing machine 1 and within the limit that does not damage the laundry. Achieve dehydration rate.

次に、脱水機2と乾燥機4との連携動作について述べる。
(図1参照)処理能率の関係上、1基の脱水機2に対して複数基の乾燥機4が配置されている。しかし、洗濯プラントにおける被洗濯物は極めて多種類であるから、脱水機2の処理能率と乾燥機4の処理能率とを完全にマッチングさせることは極めて困難であり、何れかに待ち時間を生じることが少なくない。本発明は、脱水機2の搾り時間を出来るだけ延長する形でマッチングを図り、無駄待ちさせないようにする。
すなわち、各乾燥機4のそれぞれから「乾燥動作中であるか否かを表す乾燥作動状態表示信号γ」を発信させる。
自動制御装置CPUは,複数基の乾燥機4の稼働状態を総合的に判断し、「複数基の乾燥機の全部が動作中であるか、少なくとも1基が空いているか」を識別する。
Next, the cooperative operation between the dehydrator 2 and the dryer 4 will be described.
(See FIG. 1) Due to the processing efficiency, a plurality of dryers 4 are arranged for one dehydrator 2. However, since there are so many kinds of laundry in the washing plant, it is extremely difficult to perfectly match the processing efficiency of the dehydrator 2 and the processing efficiency of the dryer 4, and there is a waiting time for either. There are many. In the present invention, matching is made in such a way as to extend the squeezing time of the dehydrator 2 as much as possible so as not to waste time.
That is, a “drying operation state display signal γ indicating whether or not a drying operation is being performed” is transmitted from each dryer 4.
The automatic control device CPU comprehensively determines the operating state of the plurality of dryers 4 and identifies whether “all of the plurality of dryers are operating or at least one is free”.

全部が動作中であると認識されると、自動制御装置CPUは脱水機2に対して作動指令信号βを与えず、搾り作動を延長継続させる。
何れか1基の乾燥機4が空けば、自動制御装置CPUは脱水機2に対して作動指令信号βを与え、搾り作動を中止して排出作動に進ませる。
脱水機2は排出作動によって脱水済みの洗濯物を移送コンベア3に排出する。
この場合、乾燥機4が空いてから排出作動を始めるので、「乾燥機は、脱水機の排出時間Tbだけ待たされるのではないか」と危惧されるかも知れないが、移送コンベア3の上に前回サイクルの脱水処理済み洗濯物が搭載されているので、待ち時間は生じない。
1基の脱水機に対して複数基の乾燥機が配設され、かつ両者の間に移送コンベア3が設置されているので、脱水機と乾燥機とのタイムマッチングは、マクロに合わせておけば足りる。これを比喩的に言えば、脱水機と乾燥機とのサイクル(周波数)を合わせておけば良く、位相差が有っても移送コンベアで吸収される。
When it is recognized that all are operating, the automatic control device CPU does not give the operation command signal β to the dehydrator 2 and continues the squeezing operation.
If any one of the dryers 4 is empty, the automatic control device CPU gives an operation command signal β to the dehydrator 2, stops the squeezing operation, and proceeds to the discharging operation.
The dehydrator 2 discharges the dehydrated laundry to the transfer conveyor 3 by the discharging operation.
In this case, since the discharge operation is started after the dryer 4 is empty, it may be feared that “the dryer will wait for the discharge time Tb of the dehydrator”. There is no waiting time because the cycle is loaded with dehydrated laundry.
Since a plurality of dryers are arranged for one dehydrator and the transfer conveyor 3 is installed between the two dryers, the time matching between the dehydrator and the dryer can be made according to the macro. It ’s enough. To put it metaphorically, it is only necessary to match the cycle (frequency) of the dehydrator and the dryer, and even if there is a phase difference, it is absorbed by the transfer conveyor.
