2. Description of the Related Art FIG. 2 is a schematic view showing a conventional example of a counter flow type continuous washing machine. In order to automatically and continuously treat cloths (hereinafter, referred to as linen) as objects to be treated for pre-washing, main washing, and rinsing, N tanks are arranged in line. In the present invention, N is 2 or an integer of 2 or more. In this conventional example (FIG. 2), N = 5. First tank A, second
Tank B, third layer C, fourth tank D, and fifth tank (Nth tank) E
Are arranged in a row so that water does not flow between the tanks unless a pipe described later passes therethrough. The linen (not shown) is put into a chute-shaped linen inlet 11, stirred in each tank while being sequentially transferred from the first tank A to the fifth tank E, and discharged from the linen outlet 12 after washing.
In order to transfer the linen while preventing the liquid from flowing between the tanks, a known structure (for example, Japanese Patent Publication No. 54-11618) is used.
No.) applies.

In this conventional example, while linen is sequentially transferred from the first tank A to the fifth tank E, the linen is pre-washed in the first tank A, washed in the second tank B and the third tank C, and then washed. Rinse in fourth and fifth tanks D and E. However, the distribution of work processes in the 5-tank counter-flow continuous washing machine is not limited to the order of pre-washing, main washing, main washing, rinsing, rinsing as in the conventional example. For example, pre-washing, pre-washing, main washing, book Washing
Arbitrary distribution, such as rinsing, etc., is also possible. In this case, the supply and drainage lines are slightly changed.

In this conventional example (FIG. 2), fresh water 13 is supplied to a fifth tank E for rinsing, and washing water 14 is supplied to a third tank C. As the washing water 14 in this case, cold water, hot water, or recovered reused water is appropriately used. A drain valve 16a is provided at the bottom of each tank.
To 16e.

The first tank A for pre-washing and the second tank B for main washing are provided with overflow pipes 17a, 17b for controlling the water level. Further, an overflow pipe 17d for controlling the water level is provided in the fourth rinsing tank D, and water overflowing from the overflow pipe 17d is supplied to the lint screen 19.
Through the collection tank 20. Recovered in the recovery tank 20 water is fed to the relay tank 21 by a pump P _1, it is fed to the linen entrance 11 of the chute shaped further by the pump P _2. This feed water soaks the linen charged into the linen inlet 11 and flows it into the first tank A for pre-washing.

A counter flow pipe 18c is provided so that the washing water used in the third tub C for main washing flows into the second tub B for main washing, and a fifth tub E for rinsing is provided.
A counter flow pipe 18e is provided so that the rinsing water in the inside flows into the fourth tank D for rinsing again.
By the action of these counter flow pipes 18c and 18e, the washing water and the rinsing water flow from right to left in the figure, that is, in the direction opposite to the linen transfer direction, and function as a counter flow type washing machine. In the conventional example shown in FIG. 2, as described above, while linen is sequentially transferred into the N tanks arranged in a line, rinsing water or washing water is caused to flow in a direction opposite to the linen transfer direction. . The linen charged in the first tank A is pre-washed by being stirred in the first tank A,
After being transferred in the tank B and the third tank C, they are agitated while being thoroughly washed, and then transferred in the fourth tank D and the fifth tank E, and then rinsed with fresh water 13 while being agitated. Exit 1
Unloaded from 2.

[0007]

In the conventional counter-flow technique, pre-washing, main washing and pre-washing are performed while linens are sequentially transferred into a plurality of tanks as illustrated with reference to FIG.
Rinsing can be advanced as an automatic integrated operation, and linens can be washed efficiently. However, dyeing cannot be carried out continuously or concurrently with the washing operation. For this reason, for example, in order to dye linen that has been washed, it is necessary to provide a dyeing machine separately from the washing machine and operate it individually. Accordingly, the entire machine is large and heavy, requiring a large space for installation and high cost. In addition, a large amount of labor is required for operation. The present invention has been made in view of the above circumstances, and a dyeing operation can be performed using a single machine at the same time as a washing operation.
It is an object of the present invention to provide a continuous washing and dyeing machine.

[0008]

The main reason for having to separate the washing machine and the dyeing machine in the prior art is that the independence between the washing tub and the dyeing tub must be maintained. Because there was no.

This problem will be described below with reference to FIG. 2 showing a conventional multi-tank type washing machine. As described above, the five-tub type washing machine has the first
By appropriately setting the work distribution of the tank to the fifth tank, each tank can be pre-washed, main-washed, and rinsed. Then, it can be easily conceived to perform washing in the first to fourth tanks (continuous operation of pre-washing, main washing, and rinsing) and dyeing in the fifth tank. However, when trying to put the above idea into practice, the staining solution in the fifth tank E is replaced by the counter flow tube 18e.
Through the fourth tank D. Therefore, the fifth tank E
And the fourth tank D lacks mutual independence, and the fifth tank E cannot be handled as a single dyeing tank.

Considering these problems in mind, for example, in a continuous washing machine of N tubs (N is an integer of 2 or more), continuous addition of only a dyeing tub in an extended row of the tubs would be a continuous process. Washing and dyeing cannot be performed.
With respect to the rows of tubs in a continuous tub washing machine, the number of dyeing tubs must be increased so as not to impede the continuity of linen transfer and to have independence in the flow of liquid. (Washing with a single mechanical equipment, simultaneous operations of staining) The purpose of on the basis of the above considerations to achieve a continuous type washing and dyeing machine according to the present invention, the means for agitating the linen

[0013]

According to the present invention, there is provided a continuous washing and dyeing machine having the above configuration.
For example , the linen can be transferred from the Nth tank to the (N + 1) th tank, and the liquid can be prevented from flowing from the (N + 1) th tank to the Nth tank. The washing operation and the dyeing operation by the (N + 1) th tank to the (N + n) th tank can be operated independently at the same time. Here, the simultaneous operation is possible in view of the relationship between the times when the work is operated, and in view of the transfer of the linen, which is the object to be processed, the linen after the washing operation is immediately advanced to the (N + 1) th tank and flown into the series. Can also or as mentioned above
It is also possible to interrupt and stop the dyeing operation that has been performed in the series as described above, and perform the washing operation using all the N + n tanks arranged in a line. In this case, each of the N + n tanks is allocated for pre-washing, main washing, or rinsing, and linens are continuously transferred.

As in the prior art, the first to fifth tanks A to E are lined up so as to transfer linen to the right and to prevent liquid from flowing without passing through a pipeline. It is.
The sixth tank F, which is the (N + 1) th tank, is extended adjacent to the fifth tank E, which is the Nth tank, in the linen transfer direction, and the N + nth tank, which is the N + n tank, is further extended in the linen transfer direction. 7
A tank G is provided. Although not shown, a means for stirring linen is provided in the sixth tank F and the seventh tank G in the same manner as in the first tank A to the fifth tank E, and the linen is transferred to the right side of the drawing. The liquid is prevented from flowing freely (specific structure is the same as that of Japanese Patent Publication No. 54-11618). The added sixth tank F and seventh tank G are installed so that they can be used as a dyeing tank in principle, and are used to wash the inside of the tank by spraying the washing water 15. Nozzle 15

Reference numeral 4 'denotes a supply pipe of cold water or hot water as washing water. An overflow pipe 17a is provided in the first tank A as in the conventional example. The second tank B has a counter flow pipe 18b having a counter flow valve 24b, and a counter.
An overflow valve 25b is provided for controlling the water level in the tank when the tuff flow valve 24b is closed . The third tank C is provided with an overflow pipe 17c. Below the overflow tube 17c, together with the recovery tank 22 to store and recover the washing water overflowed is provided, the pump P ₃ and for feeding to the second vessel B the water stored in the recovery tank 22 Piping is provided. Pumps P ₂ and piping for pumping reuse water in the relay tank 21 to the linen entrance 11 of the chute-shaped is provided in this embodiment. In this example, a counter flow pipe 18d for flowing the washing water in the fourth tub D to the third tub C is provided, and an overflow pipe 17e for controlling the water level in the fifth tub E is provided. A collection tank 23 is provided for collecting and storing overflow water from 17e. In this case of using the five tank E as finishing rinse tank clean overflow water next to fresh water in the recovery tank 23 is recovered, it feeds feed by the pump P ₄ to the relay tank 21, or pump P ₅ Thus, a pipeline is provided for supplying the fourth tank D with reused water.

A sixth tank F, which is the added N + 1th tank, has:
Counter flow pipe 18 communicating with the fifth tank E which is the Nth tank
f is provided, a counter flow valve 24f for controlling the opening and closing of the communication is provided, and an overflow valve 25f for controlling the water level in the tank is provided. The added seventh tank G, which is the (N + n) th tank, is provided with a counterflow pipe 18g that communicates with the sixth tank F that is the (N + 1) th tank, and a counterflow valve 24g that controls opening and closing of the communication is provided, and , An overflow valve 25g for controlling the water level in the tank is provided. A dye tank 26 is provided above the sixth tank F, and the dye is supplied from a dye storage tank 27. Dye valve 2

The Glauber's salt solution can be injected into the sixth tank F which is a tank.

An example in which the continuous washing and dyeing method according to the present invention is performed using the washing and dyeing machine (FIG. 1) configured as described above will be described below. Sixth tank F by applying the present invention
The conventional apparatus, which is a base for adding a second tank and a seventh tank G, has first to fifth tanks A to E. In the present embodiment, these first to fifth tanks A to E are also provided. Therefore, it is possible to easily wash the linen using the first tub A to the fifth tub E of the present embodiment (FIG. 1). That is, the steps of prewashing, main washing, and rinsing are continuously performed as follows. Continuously performing here means that each process is performed automatically and continuously, such as immediately transferring linen after pre-washing to main wash and immediately rinsing linen after main wash. It represents.

The object to be processed (not shown) is turned on linen inlet 11, the recovered water in the relay tank 21 pumped by the pump P ₂ (as will be described later, relatively to overflow from the fifth tank E rinse step First bath A
After being stirred in the second tank B, it is stirred and pre-washed. Wash water for prewashing are supplied with pumped into the second vessel B the recovered water in the recovery tank 22 by a pump P _3. The linen that has been prewashed is then transferred into the third tank C and stirred, and further transferred into the fourth tank D and washed while being stirred. As the washing water for the washing, with recovered water in the recovery tank 23 is supplied to the fourth tank D by the pump P _5, arrow 14 '
Washing water (cold water or hot water) is also supplied.
The washing water overflowing from the fourth tub D flows through the counterflow pipe 18d to the third tub C, and is further stored in the collection tank 22 via the overflow pipe 17c.
In this way, in the main washing step, the counter flow type washing is performed while the washing water is flowing in the left direction in the figure, opposite to the linen transfer direction (right direction in the figure).

The linen washed as described above is the fourth
It is transferred from the tank D to the fifth tank E, where it is rinsed. The clean water for rinsing is supplied to the fifth tank E as indicated by an arrow 13, and the overflow water is supplied to the overflow pipe 18d.
And is collected in the collection tank 23 and stored. The overflow water of the rinse is cleaner than the main wash water and the pre-washed wash water. Therefore, solid foreign matter is filtered off and stored by the lint screen 23a , and the pump P _{4 is} used as reuse water. or it is delivered by the pump P _5. In this way, the linen is rinsed in the fifth tub E to complete the washing.

As described above, the linen which has been washed through the pre-washing step, the main washing step, and the rinsing step while being sequentially transferred in the first tank A to the fifth tank E is further transferred to the sixth tank F. After being transferred and stirred, it is dyed as follows while being transferred to the seventh tank G and stirred. That is, the water for dyeing is supplied to the seventh tank G as indicated by an arrow 29, and is supplied to the sixth tank F via the counter flow pipe 18g and the counter flow valve 24g. The dye in the dye tank 26 is supplied to the sixth tank F via a dye supply valve 26a. In the embodiment of the present method, the counter flow valve 24f is closed, and the dye-containing water in the sixth tank F is shut off so as not to flow to the fifth tank E for rinsing. Thereby, the sixth tank F for dyeing is independent of the fifth tank E for rinsing with respect to the exchange of water in the tank. The linen transferred into the sixth tank is dyed by adding a sodium sulfate solution as a dyeing aid from the sodium sulfate tank 28 while being stirred in the water containing the dye. The dyed linen is transferred into the seventh tank G, and the fresh water indicated by the arrow 29 is poured and stirred. Then, the excess dye that has been dyed on the dyed linen elutes into water, and the dyeing operation is completed.

The continuous washing and dyeing method of the embodiment described above with reference to FIG. 1 is applied to the treatment of contaminated linen, and the contaminated linen is pre-washed and booked in the first to fifth tanks as described above. After washing and rinsing, this was transferred to a sixth tank and dyed as a continuous process. However, if the linen to be dyed is not particularly contaminated, the pre-washing, main washing,
It is wasteful to go through each rinsing step. In such a case (see FIG. 1), it is appropriate to pass through the first tank to the fifth tank, and to dye using the sixth tank F and the seventh tank G in the same manner as in the previous example. An embodiment in such a case will be described below. Clean water is supplied to each tank from the first tank A to the fifth tank E, and linen (not stained) to be dyed is introduced into the first tank A from the linen inlet 11. Then, the mixture is stirred in water while being transferred to the fifth tank E, and washed with water. In this example,
The reason for washing with water without passing it through literally is that even if it is new linen, there is dirt and deposits during manufacturing and there are deposits (dust) during storage and transportation. It is better to do it. However, in this case, the cycle for passing the linen through each tank is relatively short. After the linen is relatively easily washed in the first to fifth tanks, it is transferred to the sixth tank and dyed in the same manner as in the previous example.
Furthermore, it transfers to 7th tank similarly to a previous example, and finishes.

In the embodiment of the above method, the linen was passed through the first to fifth tanks (or simply washed with water), and the dyeing operation was performed in the sixth and seventh tanks. In such a case, while dyeing linen in the sixth and seventh tanks, the first
-The fifth tank is idle. In order to eliminate the partial idleness of such mechanical equipment and improve the overall operation rate, the sixth
In parallel with the linen dyeing operation in tank 7
It is also possible to perform a different linen washing operation from the fifth tub. Next, an embodiment in which washing and dyeing are performed in parallel will be described.

Although not shown, for convenience of explanation, a new lump of linen to be dyed is named group a and a lump of soiled linen is named group b. The linen of the group a is passed through the first to fifth tanks only by washing with water as in the above-mentioned embodiment, and then dyed in the sixth and seventh tanks over time. While dyeing the linen of the group a, the linen (soil) of the group b is put into the linen inlet 11, and is sequentially transferred from the first tank A to the fifth tank E while pre-washing, main washing and rinsing. After each step of washing. The washing using the first to fifth tubs may be performed in the same manner as in the conventional 5-tank type continuous washing machine shown in FIG. The linen of the b group reaches the fifth tank E and is rinsed. Above b
Group linen is further subdivided into two groups. Group b for dyeing after washing
₁ and referred to, referred to as if washing enough things (do not require staining) and group b _2. After taken out of the linen linen exit finishing staining of a group, b ₁ group of linen passed through the sixth vessel F, a seventh tank G, dyed operation in the same manner as described above in Example, linen inlet Linen Exit 1 from 11
Perform continuous washing and dyeing process up to 2 hours. b. If the linen of group ₂ has been washed and rinsed in the fifth tub E, pass it through the sixth and seventh tubs as described below (or do the same simple flush). It is carried out from the linen exit 12. In this case, the sixth vessel F finishing staining preceding a group of linen (staining only), was carried out from the seventh tank G, even b ₂ groups be a subsequent linen b ₁ group Prior to receiving these into the sixth tank F, the drainage valves 16f and 16g are opened to discharge the dyeing water inside, and the cleaning nozzles 15f and 15g spray cleaning water to clean the inside of the tank. The reason is as follows. If subsequent linen not stain a b ₂ groups, 6 were linen staining a group, washing staining seventh tank, and unless removed in a subsequent b ₂ groups linens since thus depositing the dye, in order to prevent this, and, even when the subsequent linen repeated dyeing operation a linen b ₁ group, intracisternal while discharging the used dye solution degraded Wash
This is because applying a dyeing operation for the new staining solution and re-formulation of b ₁ group linen (pre-washing).

The linen of the b ₁ group (not stained)
Considering the method of the above embodiment with respect to FIG. 1, it is noted that there is still room for improvement. That is,
The operation method of terminating the washing operation and transferring the linens, which are only washed and not dyed, from the first tank A to the fifth tank E and pass straight through the sixth tank F and the seventh tank G is shown in FIG. The sixth tank and the seventh tank are idled without using any of the mechanical equipment shown in FIG. Originally, the 6th and 7th tanks were added to perform dyeing in an integrated process, but when dyeing is not to be performed, we would like to consider an effective use method. In particular, in the case of processing a large amount of linen of b ₁ group, such a request is strong. Provided that no major modification is made to the mechanical device of FIG. 1, it is premised that the first tank A is used for pre-washing and the seventh tank G is used for rinsing, but the second tank B to the sixth tank are used. F
Each of the five tanks up to this point is pre-washed,
It is easy to assign to main washing and rinsing. This assignment change is performed by opening and closing the valves shown in FIG.
Alternatively, it can be easily performed by adding a little pipe with a valve. The following embodiment is recommended as an example of effectively allocating the work distribution by using all the tanks from the first tank A to the seventh tank G which is the (N + n) th tank. "First and second
Pre-wash the tank, rinse the third and fourth tanks, and rinse the fifth, sixth and seventh tanks. ”This plan is for three tanks to be applied when there is a high need for complete rinsing. (5th to 7th) are assigned to the rinse. In addition, according to the state of the linen to be washed and dyed, each tank is assigned to an arbitrary operation, and all the N + n tanks (seven tanks in the example of FIG. 1) are used for pre-washing / washing. A three-step washing operation consisting of main washing and rinsing can be performed continuously and continuously.

As described above, each of the examples includes (a) a series of washing operations using N tubs and a dyeing operation using n tubs, and (b) N tubs. Parallel operation of washing operation and dyeing operation using n tanks, (c) N + n
The continuous integrated operation of the washing operation using all of the individual tubs has been described. However, according to the change of the linen state of the work object and the change of the processing specifications, the above (a), (b), (c) It is also possible to switch the operation form of each section mutually. For example, it is also possible to switch from the washing / dyeing parallel operation of the item (b) to the integrated operation of the washing operation of the item (c) by performing a flow channel changing operation. Further, for example, by performing the flow path changing operation from the integrated washing operation in the item (C), the operation can be switched to the washing and dyeing series operation in the item (A), or can be switched to the washing and dyeing parallel operation in the item (B). . Further, it is also possible to switch between the washing and dyeing series operation of the above item (a) and the parallel operation of the item (c).

[0026]

As described above, according to the continuous washing and dyeing machine of the present invention, since the dyeing operation can be performed using a single machine at the same time as the washing operation, the overall washing and dyeing can be performed. Work can be performed efficiently with a single machine and with a small amount of labor.
