Description

  The present invention relates to a technique of a cleaning device, and more particularly to a control technique capable of executing a continuous cleaning process under optimum conditions for each cleaning object while the cleaning object is suspended.

  In recent years, it has been pointed out to the cleaning industry that the quality of cleaning has declined due to intensifying price competition. In addition, it has been pointed out that the investment in environmental pollution and environmental measures is relatively small, and that it is behind the common belief of Japanese society that it is “environmentally friendly”. In recent cleaning apparatuses, there is an urgent need to switch from dry cleaning using a conventional solvent, which is also a problem in the cleaning industry.

  As the above-mentioned problem in cleaning, the problem arising from the cleaning characteristics can be considered. Methods for cleaning clothes and the like include dry cleaning using a non-aqueous solvent such as a volatile organic solvent such as a petroleum solvent as a cleaning medium, and laundry using a large amount of water as a cleaning medium. The dry cleaning has an excellent detergency against oil-soluble dirt, but the dry soap does not have enough detergency against water-soluble dirt. On the other hand, a laundry using water requires a large amount of water and has a high detergency against aqueous soils, although it has a low detergency against oily soils. In particular, when a wool-based cleaning object is washed with water, it tends to shrink and lose its shape. Therefore, dry cleaning using mainly a solvent is generally performed as commercial cleaning.

  Also, the influence on environmental resources and the like derived from the above characteristics cannot be overlooked. That is, since the cleaning medium for dry cleaning is a volatile solvent, the ozone layer may be destroyed and carcinogenic substances may be absorbed into the body. In addition, when the dry cleaning device is operated, industrial waste such as old oil, filters, and carbon is discharged. On the other hand, even in laundry, dry cleaning uses a relatively small proportion of water, but laundry is 100%. In order to return such rinsing water to the environment, it is necessary to purify waste water.

  In addition, there are issues that correlate with cleaning quality and efficiency. In cleaning work, it is extremely efficient if a large amount of clothes can be cleaned at once. In recent years, in dry cleaning, objects to be cleaned are put together in a large cleaning device. This is to reduce the cleaning cost and perform a large amount of cleaning at a time. However, if it is delicate clothes etc., deterioration and damage may occur. On the other hand, if cleaning is performed manually or transported one by one in each process, the efficiency is poor.

  In view of the above problems, attempts have been made to improve such problems. For example, in Patent Document 1, a cleaning object conveying conveyor that suspends and conveys a cleaning object, a pre-washing unit that is provided in a conveying path of the cleaning object conveying conveyor and pre-washes with water or ozone water, and a cleaning liquid An industrial cleaning device has been proposed that consists of a washing liquid washing part, a main washing and rinsing part that performs main washing and rinsing with water or ozone water, and a dehydration part that performs dehydration. It is comprised so that it may process (refer patent document 1).

  Further, in Patent Document 2, at least a conveyer unit that hangs and conveys a hanger on which an object to be cleaned is hung, a washing unit that performs washing, and a rinsing unit that performs rinsing are provided at the conveyance path of the conveyor unit. In the industrial cleaning apparatus provided, the washing section includes spraying means for spraying a cleaning liquid onto the cleaning object, and the rinsing section opens and closes in two, and when the cleaning object is closed, the cleaning object is hung on the hanger. It has been proposed to include a tank constituting a box-shaped container, a driving means for opening and closing the tank, and a cleaning liquid supply means for supplying a cleaning liquid to the tank. Can be reduced in size (see Patent Document 2).

Japanese Unexamined Patent Publication No. 6-182086 Japanese Patent No. 3151098

  Certainly, in the cleaning devices described in Patent Documents 1 and 2, clothes and the like are hung on a hanger and are sequentially conveyed by a conveyor means or the like, compared with the previous cleaning device, and washed, rinsed and dehydrated. It can be said that it is useful in that a large amount of clothes and the like can be washed at a time by such continuous operation, and the apparatus configuration required for the cleaning device can be reduced in size.

However, the cleaning device and the like have the following problems.
In other words, when washing clothes, etc., the washing liquid is directly sprayed by the spraying means, etc., so that the surface of the clothes, etc. is impacted, and this is sufficiently ensured in terms of ensuring the quality of the clothes, etc. It wasn't what it was. In addition, according to the jetting means, since a constant cleaning liquid is sprayed regardless of the difference in the degree of dirt on clothes, etc., the efficiency is poor, it is not possible to deal with local dirt, and unevenness of the washing liquid has occurred. .

  In Patent Documents 1 and 2, clothes or the like are immersed in the rough rinsing part or the main rinsing part, or a separate box tank is provided, and the object to be cleaned is not shaken up and down when rinsing the clothes or the like. Although clothes and the like are rinsed sufficiently, it cannot be said that such a dipping method alone is sufficient for rinsing the washing liquid sufficiently. In particular, it is necessary to ensure a large amount of water for the immersion of the cleaning object, and this water resource is not efficiently used from the viewpoint of protecting the water resource environment.

  Furthermore, in recent years, there has been a tendency for cleaning shop customers to prefer high-value-added cleaning that guarantees the quality of hand-washing or close to hand-washing even if the price is somewhat high. The conventional method of cleaning a large amount of objects to be cleaned at a time cannot cope with the degree of contamination for each object to be cleaned, individual customer needs, etc., and as described above, cleaning is performed in each cleaning step. The quality was not sufficiently secured.

  Therefore, the present invention relates to a cleaning device that solves the above-described conventional problems, improves the problems of the conventional cleaning device, and considers various effects on the environment, and improves the quality of the cleaning object. The objective is to build a device that increases the cleaning efficiency and matches the needs of customers while ensuring sufficient security.

Are connected to a cleaning liquid tank (not shown) via valves, pipes, etc., and the cleaning liquid passes through the nozzle holes 13 a, 13 a. It is sprayed continuously. The valve is controlled so that the amount of the cleaning liquid can be changed and opened and closed.

  In order to spray the cleaning liquid in the mist form at the nozzle holes 13a, 13a, etc., for example, various types such as a disk type using a mist generating disk or a high pressure type spraying the cleaning liquid at a high pressure after narrowing the nozzle hole 13a, etc. Mist means can be used. Moreover, various nozzles, such as a fan-shaped nozzle, a full cone nozzle, and an empty cone nozzle, can be used for the nozzle holes 13a, 13a.

  Thus, the inside of the housing 12 is configured to be filled with the cleaning liquid sprayed in the form of a mist to form a cleaning liquid atmosphere. The cleaning liquid 3 is sufficiently applied to the cleaning object 3 transferred to the housing 12 along the conveyance path 5 while being suspended in the space of the cleaning liquid atmosphere. Therefore, it is possible to perform washing without rubbing the cleaning object 3 as in the past, and to prevent deterioration of clothes. In addition, the coating liquid can be uniformly applied without unevenness of the cleaning liquid. As long as the nozzle portions 13, 13... Are not directly sprayed onto the cleaning object 3 in the housing 12, the arrangement and the number of nozzle holes 13 a are not limited thereto. The washing device 6 is connected to a controller 501. Details will be described later.

  A cleaning liquid spraying device 14 is disposed in the housing 12 as spraying means for spraying the cleaning liquid directly onto a locally soiled portion of the cleaning object 3. The cleaning liquid ejecting apparatus 14 is composed of an articulated robot arm, and a support arm 16 is disposed at a substantially upper center of a cylindrical base 15, and the arm is passed from the support arm 16 through swinging parts 17 and 18. The parts 19 and 20 are connected. The arm portions 19 and 20 are configured to be vertically rotatable by an actuator such as a hydraulic or electric motor (not shown). The cleaning liquid ejecting apparatus 14 is configured to be rotatable about the base 15 as a rotation center.

  A cleaning liquid spray nozzle 21 is disposed at the end of the arm portion 20, and a spray nozzle hole 21 a is formed at the tip of the spray nozzle 21. The cleaning liquid ejecting apparatus 14 is connected to a cleaning liquid tank (not shown), and the cleaning liquid in the cleaning liquid tank is passed through an introduction pipe (not shown) extending along the base 15 and the support arm 16 and the like. Sprayed from the spray nozzle hole 21a. Since the cleaning object 3 suspended on the hanger 4 is transferred into the housing 12 in a state substantially parallel to the transport path 5, the cleaning liquid can be effectively sprayed onto the surface of the cleaning object 3.

  Further, a dirt sensor 21b as a detecting means for detecting the dirt portion 3a of the cleaning object 3 is disposed at the end of the arm portion 20 and in the vicinity of the spray nozzle hole 21a. The dirt sensor 21b can detect a spot of dirt such as fat, oil, protein, sugar in the cleaning object 3. Specifically, an image sensor, a reflection sensor, or the like that detects the stain location based on a difference in color tone is used. The dirt sensor 21b is connected to a controller 501 described later.

  In the washing apparatus 6, the cleaning liquid injection device 14 may include a plurality of fixed injection nozzles 21 instead of the movable injection nozzle 21 as described above. In other words, the cleaning liquid ejecting apparatus 14 has a fixed arm fixed in the front and rear and up and down directions inside the housing 12, and spray nozzles 21, 21. 21... May be provided with the same number of injection nozzle holes 21 a. Further, the dirt sensor 21b may be configured to be fixed at several locations inside the housing 12. By adopting such a configuration, a device configuration with complicated structure and control such as the swinging portions 17 and 18 and the arm portions 19 and 20 is not required, and a simpler configuration can be achieved.

  As described above, by disposing the cleaning liquid ejecting device 14, the cleaning liquid can be directly applied to local dirt even if the cleaning liquid is insufficiently applied only by being transferred in the cleaning liquid atmosphere described above. Can be injected. Therefore, it is possible to reduce the amount of unnecessary cleaning liquid sprayed and to perform cleaning effectively.

  In addition, in order to enable the local injection, the nozzle hole 21a preferably uses a linear nozzle or the like and can perform continuous or pulsating injection. Further, the cleaning liquid ejecting apparatus 14 is disposed only on one side of the cleaning object 3, but the same cleaning liquid ejecting apparatus 14 may be disposed on the opposite side through the cleaning object 3. In such a case, it is possible to reliably spray the cleaning liquid onto the dirty portion 3a regardless of the front and back of the cleaning object 3.

Next, the cleaning liquid fixing unit 7 according to this embodiment will be described below.
The cleaning object 3 to which the cleaning liquid is applied by the cleaning device 6 passes through the cleaning liquid fixing unit 7 and then is transferred to a rough rinsing device 8 to be described later in order to fix the cleaning liquid to the dirt portion 3a and the like. The cleaning liquid fixing unit 7 is configured such that the conveyance path 5 connected to the washing device 6 and the rough rinsing device 8 has a certain length. In order to fix the cleaning liquid to the cleaning object 3, it is effective to provide a fixed fixing time between washing and rinsing of the cleaning object 3. In order to ensure such fixing time, the conveyance path 5 is configured to have a certain length or more.

  As shown in FIG. 1, in the cleaning liquid fixing unit 7, the conveyance path 5 is formed in a substantially U shape in a plan view. The cleaning liquid is fixed to the cleaning object 3 while being transferred from the washing device 6 to the rough rinsing device 8 without interposing between the washing device 6 and the rough rinsing device 8 at the shortest distance. Thus, the fixing time of the cleaning liquid can be ensured. By adopting such a configuration, the rough rinsing apparatus 8 can efficiently rinse off dirt on the cleaning object 3. Further, by making the conveyance path 5 in the cleaning liquid fixing unit 7 substantially U-shaped in plan view, the cleaning apparatus 1 as a whole can be reduced in size while ensuring a certain length of the conveyance path 5.

  The cleaning liquid fixing unit 7 is not only provided between the washing device 6 and the rough rinsing device 8, but also when the rough rinsing device 8 is omitted, the washing device 6 and the rinsing / dehydrating device. If it is between 9, it will not limit to the above structures. The cleaning liquid fixing unit 7 may be provided inside the washing device 6 or the rough rinsing device 8. Further, as will be described later, the conveyance speed of the conveyance unit 5a to be conveyed may be reduced.

Next, the rough rinsing apparatus 8 as a rinsing means according to the present embodiment will be described below.
As shown in FIGS. 1, 4, and 5, the cleaning object 3 to which the cleaning liquid is fixed is transferred to the rough rinsing apparatus 8 as the rinsing means according to the present embodiment via the cleaning liquid fixing unit 7. “Rinse” in the present embodiment refers to rinsing off cleaning liquid, dirt, and the like adhering to the cleaning object 3 with rinsing water, and includes rough rinsing and main rinsing. That is, in the rough rinsing apparatus 8, before the main rinsing in the rinsing / dehydrating apparatus 9 described later, dirt and cleaning liquid adhering to the cleaning object 3 are rinsed off in advance.

The carry-in port 23a and the carry-out port 23b are provided with an openable / closable door portion or a book-like curtain portion (not shown), and the inside and outside of the housing 23 are separated.

  In the housing 23, rinsing water injection devices 24 and 24 for directly injecting rinsing water onto the cleaning object 3 are arranged. The rinsing water jetting device 24 is disposed on a support column 25 fixed so as to be perpendicular to the lower plane of the housing 23 so that a sliding portion 26 can be slid repeatedly in the vertical direction. An injection nozzle portion 27 is attached to the sliding portion 26 so as to be substantially perpendicular to the support column portion 25 and substantially parallel to the transport path 5. The cleaning object 3 suspended on the hanger 4 is transferred into the housing 12 in a state of being substantially parallel to the transport path 5. Therefore, the rinsing water spray devices 24 and 24 can be sprayed directly and effectively onto the surface of the cleaning object 3 by arranging the spray nozzle portion 27 so as to be substantially parallel to the transport path 5. . In addition, nozzle holes 27a, 27a,... Are formed in the ejection nozzle portion 27 so as to face the cleaning object 3 along the longitudinal direction.

  The rinsing water injection device 24 is connected to a rinsing water tank (not shown) via a valve, a pipe, etc., and the rinsing water in the rinsing water tank is supplied to the support column 25, the sliding portion 26, and the injection nozzle.

Then, the rinsing water is ejected from the ejection nozzle portion 27 while the sliding portion 26 is repeatedly slid in the vertical direction along the support column portion 25.

Here, the rinsing water injection means in the rough rinsing apparatus 8 will be described in detail below.
As described above, in the rough rinsing apparatus 8, rinsing water is jetted from the jet nozzle portion 27 so as to be substantially perpendicular to the cleaning object 3. The rinsing water injection means is schematically shown in FIGS. 6 (a) and 6 (b). In this embodiment, the width of the rinsing water sprayed from the nozzle hole 27a can be adjusted on the order of micrometers. Conventional rinsing water spray means simply sprays the cleaning object 3 directly, and with such spray means, it is not easy to quickly and reliably rinse off dirt and cleaning liquid adhering to the cleaning object 3, In addition, a large amount of water was used. According to the rinsing water jetting means in the present embodiment, it is possible to effectively remove dirt or the like that has penetrated to the crossing site in clothes or the like that are complicatedly shaped by the crossing of the warp and weft of the cleaning object 3. .

  As shown in FIG. 6A, a plurality of nozzle holes 27a, 27a,... Are formed on the surface of the injection nozzle portion 27, and the nozzle holes 27a, 27a,. It is formed to become. The nozzle holes 27a, 27a, ... are connected to an introduction pipe 27b extending from the rinsing water tank so that rinsing water can be injected. The nozzle holes 27a, 27a,... Are provided with linear nozzles or the like in order to enable local injection. Then, rinsing water is jetted from the jet nozzle portion 27 so as to be substantially perpendicular to the surface of the clothes.

  By setting it as such a structure, the rough rinsing of the cleaning target object 3 can be performed effectively. That is, the dirt between the yarns cannot be rinsed off simply by immersing the cleaning object 3 in the rinsing water. Further, in the rough rinsing apparatus 8, dirt and cleaning liquid adhering to the cleaning object 3 are rinsed off, and a more careful rinsing is performed together with the main rinsing described later. When the above-described immersion means is used, a large amount of water is required for exchanging the waste liquid. According to the rough rinsing apparatus 8 according to the present embodiment, not only can dirt be reliably rinsed out, but also a small amount of rinsing water can be injected in a short time, thus contributing to protection of water resources. can do.

  In this embodiment, it is preferable that the diameter W1 is 0.1 mm to 0.5 mm. That is, ordinary clothing such as clothing is expressed by warp density and weft density (the number of yarns between 1 inch), and the density is usually 1 inch although it varies greatly depending on the weaving method (plain weave or twill weave) and count. About 30 to 80 warps (wefts) are woven per (2.54 cm). In such a case, the distance W2 between the warps (wefts) is about several hundred μm. Therefore, by adjusting the caliber W1 as described above, it is possible for the rinsing water to be jetted to pass between the warps (wefts), and it is possible to effectively rinse off the dirt and the like at each crossing site. is there.

  On the other hand, in the embodiment shown in FIG. 6B, in addition to the introduction pipe 127b, an air introduction pipe 127c is connected to the injection nozzle portion 127 so that high-pressure air is mixed into the rinsing water to generate microbubbles. It is made into the composition. The microbubbles in the present embodiment refer to bubbles having a diameter of about several tens of μm to several hundreds of μm, excluding bubbles (macro bubbles) that are normally generated when rinsing water is jetted.

  The air introduction pipe 127c is connected to a high-pressure air compressor or a blower (not shown), and air is sent to the nozzle holes 127a, 127a,... Via the air introduction pipe 127c. As a method for generating microbubbles, for example, the air sent into the injection nozzle portion 127 may be mixed with rinsing water in the vicinity of the nozzle holes 127a, 127a, ... to generate microbubbles. Alternatively, in the nozzle holes 127a, 127a,..., A gas-liquid two-phase swirling flow of rinsing water and air may be generated, and microbubbles may be generated by a strong shearing action at the interface.

  The rinsing water sprayed from the spray nozzle portion 127 is adjusted so as to have an incident angle θ with respect to the normal line of the surface of the cleaning object 3. That is, since the rinsing water contains the above-described microbubbles, when the rinsing water is ejected at the incident angle θ, the microbubbles bounce on the surface of the cleaning object 3 and generate a pulse impact. By such ultra-fine vibration, dirt and the like adhering to the cleaning object 3 can be rinsed off. Compared to the rinsing water spraying means by the spray nozzle part 27, the spraying speed can be set low, so that the cleaning object 3 can be prevented from being damaged. Moreover, the effect of rinsing dirt etc. out of the cleaning object 3 can also be expected.

  In addition, in the injection nozzle part 27 * 127 which concerns on a present Example, it is set as the structure which can perform continuous or pulsating injection. In particular, it is possible to rinse off dirt and the like more effectively by pulsating the rinsing water.

Next, the cleaning liquid according to the present embodiment will be described in detail below.
In the cleaning apparatus 1, it is preferable to clean the cleaning object 3 without using a non-aqueous volatile organic solvent such as a petroleum solvent used in conventional dry cleaning from the viewpoint of environmental protection and the like. . As such a general aqueous cleaning liquid, aqueous solvents such as various liquid soaps, composite soaps, and synthetic detergents (neutral / non-alkali) can be used. However, when an aqueous cleaning solution is used, it can be reused by purifying wastewater, which is preferable from the viewpoint of environmental protection.However, when silk products or wool products are used in conventional aqueous cleaning solutions, In some cases, large shrinkage occurred in clothes. This is unsuitable for the cleaning apparatus 1 that improves the cleaning quality and increases the value added to the cleaning.

  Therefore, as shown in the present embodiment, it is preferable to use, for example, the cleaning liquid presented in Japanese Patent Application Laid-Open No. 2003-183977 as the cleaning liquid. Such a cleaning liquid contains an aqueous cleaning composition for fibers and the like. Specifically, it is characterized in that it contains a large amount of a so-called low molar addition surfactant having an alkylene oxide addition mole number of 6 or less. It is what you have. A surfactant represented by the general formula R—O (AO) n—H is provided, R is an alkyl group having 10 to 18 carbon atoms, and AO is an alkylene oxide having 2 to 3 carbon atoms. N is the number of moles of alkylene oxide added and is an integer of 2 or more. And (a) the number of added moles n of alkylene oxide is n ≦ 6, (b) the number of added moles n of alkylene oxide is 7 ≦ n ≦ 8, and (c) the number of added moles n of alkylene oxide. Is composed of three types of nonionic surfactants having 9 ≦ n.

  In addition to the surfactant that actually removes dirt, a co-solvent for facilitating adhesion of the surfactant to the cleaning object 3 is contained. Examples of cosolvents include diethylene glycol monomethyl ether, diethylene glycol monobutyl ether, propylene glycol, phenyl glycol, hexylene glycol, diethylene glycol mono-2-ethylhexyl ether, 1-methyl-3-methoxybutanol, ethanol, limonene, liquid paraffin, dimethyl imidate. One or more daridinone, N-methyl-2-pyrrolidone and the like can be contained. As a result, the fluidity of the cleaning liquid is increased, and it becomes easy to spray-apply the cleaning object 3, and the cleaning composition can be reliably adhered to the dirt.

  In addition, the content of the aqueous detergent composition for fibers in this example is not limited to the above-mentioned nonionic surfactant and co-solvent, but other anionic surfactants, cationic surfactants, various enzymes, and perfumes. Etc. may be contained. By adjusting the content ratio of these inclusions, more remarkable effects can be achieved.

  As a usage mode, for example, the cleaning liquid is adhered to the cleaning object 3 and held for 5 to 10 minutes, and then the cleaning object 3 is immersed in still water for 5 to 10 minutes to remove various kinds of dirt. be able to.

  According to such a cleaning liquid, oil-soluble dirt that could not be removed by a conventional aqueous cleaning liquid can be effectively removed. Further, shrinkage can be kept to a minimum without giving any mechanical force or other physical action to the object 3 to be cleaned, especially when washing silk or wool products. Moreover, since it does not contain noniphenol, acryl benzene sulfonate, etc. which were contained in the conventional cleaning liquid composition, it is considered as an environment-friendly composition.

  As described above, the cleaning liquid is in a static state and can remove dirt regardless of the kind of dirt. In this embodiment, the cleaning object 3 to which a large amount of a plurality of types of dirt locally adheres can also be reliably removed by using the cleaning liquid in a static mist atmosphere. . Therefore, in the cleaning device 1, the cleaning quality is improved, and the cleaning object 3 can be continuously “washed and rinsed”. Furthermore, since it is used by being sprayed in the form of mist, the discharge amount can be remarkably reduced, and the cleaning liquid and dirt can be rinsed away simply by immersing in ordinary rinsing water (static water). It is possible to simplify the apparatus configuration and shorten the cleaning time.

Next, the rinsing means and the rinsing / dehydrating apparatus 9 as the dehydrating means according to this embodiment will be described below.
As shown in FIGS. 1 and 7 to 9, a rinsing / dehydrating device 9 as a rinsing unit and a dehydrating unit according to this embodiment is disposed along the conveyance path 5 and is transferred by a conveyance unit 5 a. The main rinsing / dehydration of the object 3 is performed. The rinsing / dehydrating device 9 mainly includes a housing 28 configured to be able to hold the cleaning object 3 while being suspended on the hanger 4, and a driving device in which a plurality of the housings 28 are connected in a loop. 29. The housing 28 is rotatably disposed on a mounting portion 29 a of the driving device 29 via a support column 30. The substantially rectangular parallelepiped door portions 28a and 28a are rotated in the front-rear direction (up and down in FIG. 7) about the support column 30 by a control mechanism such as a hydraulic pump (not shown).

  The door portions 28a and 28a are formed in substantially the same shape, and a substantially central portion of the contact surfaces of the door portions 28a and 28a is formed in a concave shape outward from the corresponding contact surface. The tank portion 28b is formed inside the housing 28 with the door portion 28a in contact therewith. The tank portion 28b has a volume that can be accommodated in a state in which the cleaning object 3 such as a business suit is suspended vertically. That is, the housing 28 abuts the door portions 28a and 28a so as to sandwich the door portion 28a from two directions, so that the cleaning object 3 suspended from the transport portion 5a can be stored in the tank portion 28b. .

  In addition, a degassing device (not shown) such as a vacuum degassing device is disposed in the tank portion 28b, and the air in the tank portion 28b is discharged to the outside by the degassing device, It is in a vacuum or near vacuum. In the tank part 28b in the present embodiment, packaging members 31 and 31 are respectively disposed along the shape of the tank part 28b in order to increase the efficiency of such exhaust. The packaging member 31 is configured to have a wrapping shape in a state where the door portion 28a is in contact with the packaging member 31, and is connected to the water injection device, the deaeration device, and the like. As a material of the packaging members 31 and 31, various synthetic resins such as urethane resin and silicone resin, and elastic members such as synthetic rubber can be used.

  When the packaging members 31 and 31 are fixed to the contact surface side of the door portions 28a and 28a of the housing 28 and rotated so that the door portions 28a and 28a come into contact with each other, the packaging members 31 and 31 The cleaning object 3 is sandwiched. In a state where the door portion 28a is completely in contact, the packaging members 31 and 31 are formed in a bag shape with the coupling portions being in close contact with each other, and are configured to have high airtightness in the inside. ing.

  The packaging member 31 that is in close contact with the sachet has a volume that can be accommodated in a state where the cleaning object 3 is suspended vertically. The cleaning object 3 in a state of being suspended by the transport unit 5a is brought into contact with the door portions 28a and 28a so as to be sandwiched in two directions, whereby the cleaning object 3 can be stored in the packaging member 31. it can.

  The drive device 29 is configured such that the attachment portion 29a is driven in a loop. The attachment portion 29a is attached to a rail 29b that extends annularly on the outer periphery of the driving device 29, and is transported along the rail 29b. As a driving means of the attachment portion 29a, for example, a screw conveyor structure driven by a motor mechanism (not shown) or the like, a trolley structure manufactured by a steel path or the like can be used.

  The housing 28 is fixed to the mounting portion 29 a in a radial manner with respect to the driving device 29 via the support column 30. The conveying path 5 in the rinsing / dehydrating device 9 is formed in a substantially U shape in plan view, and the drive device 29 is formed by a substantially U-shaped portion in plan view and a straight portion along the conveying path 5. . By adopting such a shape, the cleaning device 1 can be reduced in size, and the annular transfer to the housing 28 in the drive device 29 can be efficiently performed. The transport path 5 and the rail 29b are disposed so as to be substantially parallel to each other, and the housing 28 is disposed so as to be substantially perpendicular to the transport path 5 and the rail 29b. The rinsing / dehydrating apparatus 9 is connected to the controller 501. Details will be described later.

Here, the main rinsing means and the dehydrating means in the rinsing / dehydrating apparatus 9 will be described in detail below.
As shown in FIGS. 7 to 9, in this embodiment, the cleaning object 3 is sandwiched by the housing 28 and accommodated in the tank portion 28b, and the main rinse is performed in the tank portion 28b. Done. A water injection device (not shown) is disposed in the tank portion 28b, and rinse water is injected from the water injection device into the tank portion 28b. The rinse water thus poured is poured into the tank portion 28b (packaging member 31) without leaking, and the main rinse is performed by a dipping method in which the cleaning object 3 is immersed in the rinse water. According to this dipping method, the cleaning object 3 is not rubbed together, so that the cleaning object 3 can be prevented from being damaged. In addition, since the cleaning object 3 can always be immersed in fresh rinsing water, it is possible to prevent color transfer due to decoloration of the other cleaning objects 3.

  When the rinsing water is poured into the tank part 28b (packaging member 31) by the water injection device, that is, the cleaning object 3 and the housing 28 are respectively immersed in the rinsing water. It is transported at the same speed along the transport path 5 and the rail 29b. Since this main rinsing is performed while transferring the housing 28 and the like, a plurality of cleaning objects 3 can be continuously rinsed, which is efficient. Then, the rinsing water in the tank portion 28b (packaging member 31) is drained out of the system by a drainage device (not shown).

  As the main rinsing means, in addition to the dipping method, for example, the main rinsing of the cleaning object 3 may be performed by rinsing water injection as shown in the above-described rinsing water injection nozzle portions 27 and 127. The rough rinsing device 8 rinses off dirt and the like adhering to the cleaning object 3 and then directly rinses water again to make the main rinsing. That is, in the main rinsing, an immersion method in which the cleaning object 3 is immersed in rinsing water, an injection method in which rinsing water is sprayed from the injection nozzle portion, and the like can be used.

  As described above, the injection nozzle portion is provided inside the tank portion 28b so that the nozzle hole faces the cleaning object 3. In that case, the injection nozzle portion may be fixed in the tank portion 28b, or may be inserted into and removed from the tank portion 28b. In the main rinsing, the rinsing water can be jetted by the jet nozzle part while reducing the amount of water, the water pressure, and the like as compared with the case of the above-described rough rinsing. Therefore, the amount of water is small and the cloth of the cleaning object 3 is not damaged.

  After the main rinsing of the cleaning object 3, dehydration is performed in the tank portion 28 b while being held in the tank 28 b while being held by the housing 28. A deaeration device is connected to the packaging member 31, and the deaeration device is driven to deaerate the inside of the tank portion 28 b, that is, the packaging member 31. As shown in FIG. 9, when the deaeration device is driven, the inside of the packaging member 31 is gradually depressurized, and accordingly, the packaging member 31 is inwardly in close contact with the cleaning object 3. Deformed. In the deaeration device, simultaneously with decompression, the rinsing water contained in the cleaning object 3 is drained from the packaging member 31 (housing 28).

  As described above, by allowing the main rinsing and dehydration to be performed by the same apparatus, the apparatus configuration can be simplified, and such steps can be performed continuously. That is, in this embodiment, the main rinsing and dehydration can be performed with the cleaning object 3 suspended, and a series of cleanings can be performed following the washing and the rough rinsing. Therefore, the cleaning efficiency is good, and unnecessary steps are eliminated, so that the cleaning device 1 can be narrowed, the cleaning time can be shortened, and the device configuration can be simplified. Further, by using the packaging member 31, when the cleaning object 3 is dehydrated, the packaging member 3 is elastically deformed, and the dehydration efficiency can be further increased.

  In the rinsing / dehydrating apparatus 9, the main rinsing and dehydration of the cleaning object 3 are performed by one apparatus, but the main rinsing may be performed by an independent apparatus. Further, in the rinsing apparatus 8, the main rinsing may be performed following the rough rinsing. The rinsing water injection and drainage is not limited to one time in the rinsing / dehydrating apparatus 9 and may be performed twice or three times.

  In addition, although the said packaging member 31 is arrange | positioned in the housing 28 in order to raise the efficiency of dehydration, it is not necessarily comprised. A similar effect can be achieved by ensuring that the tank portion 28b is airtight at the contact portions of the door portions 28a and 28a and does not leak in the deaerated state. Further, when the deaeration device is driven, only the inside of the housing 28 or the tank portion 28b may be heated. Furthermore, the rinsing / dehydrating apparatus 9 may be configured to include a drying means for the cleaning object 3.

  In the washing device 6, the rough rinsing device 8, and the rinsing / dehydrating device 9 in this embodiment, the cleaning objects 3 to be transferred and accommodated in the housings 12, 23, and 28 are not limited to one set, You may comprise so that washing | cleaning, rinsing, etc. of multiple sets of the cleaning target object 3 can be performed simultaneously. In accordance with the quantity of the cleaning object 3 to be washed at a time, the quantity, time, transport speed, etc. of the cleaning object 3 in each process of the washing device 6 and the like are controlled. Details will be described later.

  Then, the cleaning object 3 dehydrated by the rinsing / dehydrating device 9 is transferred through the conveyance path 5 and dried in the drying unit 10. The drying unit 10 is configured to naturally dry the cleaning object 3 by transporting it over time. As such drying means, for example, hot air may be applied or a greenhouse may be passed while the transport path 5 is being transferred.

  The cleaning object 3 dried by the drying unit 10 is then transferred to the receiving unit 11. In the receiving unit 11, ironing, packaging, and the like are performed as the final finish of the cleaning object 3. In such final finishing, the cleaning object 3 is removed from the hanger 4 and ironed, but ironing may be performed while being suspended on the hanger by a three-dimensional press or the like. The receiving unit 11 is connected to the controller 501. Details will be described later.

Further, the waste water purifying means according to this embodiment will be described below.
In the washing device 6, the rough rinsing device 8 and the rinsing / dehydrating device 9, waste water containing cleaning liquid, rinsing water, various kinds of dirt, etc. is collected in a purification device (not shown) as waste water purification means. It is made into the composition. Specifically, the purification device is connected to the housings 12, 23, and 28, and cleaning liquid and rinsing water used in the housings 12 and the like are collected in the purification device through pipes and the like. .

  The purifier includes, for example, an oil recovery type that separates and discharges oil by specific gravity separation using a filled lipophilic functional fiber or the like, a floating oil recovery type oil recovery device, and the like. After the oil content is removed, it is purified by a purification device such as a high pressure filtration type or electrolytic ionization type. The purification device is connected to a cleaning liquid tank and a rinsing water tank (not shown) so that the rinsing water used can be reused. Note that a part of the waste water may be discharged out of the system, and if the rinse water to be reused is insufficient, new rinse water may be injected into the system. .

  Since the cleaning device 1 includes the rinsing water purification means as described above, the waste water from the washing means, the rinsing means, and the dewatering means can be reused in the rinsing means, and the amount of rinsing water to be used can be reduced. It can be reduced efficiently. Moreover, since the quantity of the waste_water | drain discharged | emitted out of a system can also be reduced, it is preferable from a viewpoint of protection of water resources environment.

  The rinsing water purified by the purification means is preferably used in the rough rinsing apparatus 8 in terms of reused water, and can also be used for adjusting the temperature and pH of the cleaning liquid. It is.

Next, the control means of the cleaning apparatus according to the present embodiment will be described below.
As shown in FIG. 10, an electronic control device 500 such as a microcomputer as a control means according to this embodiment is connected to a controller 501 with the washing device 6, the coarse rinsing device 8, etc. via a communication bus 502. Has been. The controller 501 includes a communication function for communicating with each of the devices, a function for storing data and programs related to device control, a development function and a calculation function for executing the data and programs, and the like. Specifically, the controller 501 may be configured such that a CPU, a ROM, a RAM, and the like are connected by a bus, or may be configured to include all of the above functions by a one-chip LSI or the like. Good.

Therefore, an example of the cleaning information control means in this embodiment will be described below.
In the cleaning device 1 according to the present embodiment, the cleaning object 3 is controlled to be transported along the transport path 5 and cleaned by a series of devices from the supply unit 2 to the receiving unit 11. Yes. First, in the supply unit 2, the cleaning object 3 delivered from the customer is suspended on the hanger 4, and the hanger 4 is suspended on the transport unit 5a. In the supply unit 2, the cleaning information of each cleaning object 3 is input to the input unit, and the cleaning information is stored in a storage unit provided in the controller 501 or a computer-readable storage member. Is done.

  “Cleaning information” in the present embodiment includes, for example, not only the type of clothes, the degree of dirt, the dirt location, etc., but also the number of cleanings, a reference number based on the receipt slip, a customer name, a cleaning start time, a delivery date, an order date, It refers to an accompanying group of information related to the cleaning object 3 including the person in charge of cleaning. Based on the cleaning information, each cleaning process in the washing device 6 or the like is controlled so as to obtain an optimum cleaning condition. That is, based on the cleaning information such as the type of clothes and fibers, the type of dirt, and the like, compared with a data map stored in advance in the controller 501, the transfer speed of the transport unit 5a, the concentration of the cleaning liquid, the jetting speed, Each cleaning condition such as rinsing / dehydrating time is determined. As described above, the controller 501 collectively determines the cleaning conditions, thereby enabling continuous control between the cleaning steps. When a specific condition (for example, reducing the rinsing time) is designated by the customer, the cleaning information may be manually input / stored.

  The cleaning information stored in the storage unit is read by a reading sensor or the like provided in each device, and each device is controlled. In addition, information related to customers and the like is read by a sensor or the like in a receiving device 11 described later, and each cleaning object 3 can be reliably stored and managed. By controlling in this way, each cleaning process is executed under different cleaning conditions for each wear, so that the cleaning quality is ensured and customer needs can be individually met. In addition, since the apparatus for each cleaning process is controlled separately, fine conditions can be set for washing, rinsing, and dewatering, cleaning quality close to hand washing can be realized, and the cleaning apparatus 1 with higher added value can be obtained.

  In this embodiment, a bar code, an IC chip, or the like can be used as the computer-readable storage member. By using such a storage member, the cleaning object 3 can be easily managed, and if it is the barcode or IC chip, it can be attached to each cleaning object 3 without being bulky. Does not become an obstacle in the cleaning process. In this embodiment, it is preferable to use a tag-like member such as an IC tag from the viewpoint of easy handling.

  The IC tag has a structure in which a fine IC chip and a metal antenna attached to transmit and receive information are combined. Condition information written in the tag is read by a reading device such as a sensor, and writing / rewriting is possible. In the case of a barcode, only a maximum of 13 digits is stored, but in the case of an IC tag, even a small storage capacity is about 10 times or more. In addition, since information is transmitted and received wirelessly, it is not necessary to hold each one over a reading device like a bar code. For example, cleaning information is instantly transmitted at the same time as passing through the inlet 12a of the washing device 6 can do. Therefore, the controller 501 can quickly and surely acquire the cleaning information from each device, and the cleaning process can be executed non-stop, the cleaning efficiency is good, and the product management becomes easier.

  In the supply unit 2, cleaning information is stored in an IC tag, and the IC tag is attached to the cleaning object 3. The IC tag is attached at a position that does not interfere with cleaning, but can also be attached to the hanger 4. When the cleaning object 3 is suspended from the hanger 4, the transport unit 5 a disposed in the transport path 5 is transported at the determined transport speed.

  The washing device 6 is provided with a sensor for reading the cleaning information stored in the IC tag. For example, the cleaning information is transmitted to the controller 501 from a reading sensor provided in the vicinity of the carry-in port 12a. The The controller 501 determines a cleaning condition from the cleaning information, and transmits the cleaning condition to the cleaning device, thereby controlling the cleaning liquid ejecting device 14 and the like in the cleaning device 6. In the washing device 6, the type, concentration, temperature, and the like of the cleaning liquid in the transfer speed housing 12 are controlled based on the material and shape of the cleaning object 3. By controlling in this way, it is possible to ensure the cleaning quality while meeting individual customer needs. The spray amount of the cleaning liquid, the temperature in the housing 12 and the like may be manually adjustable.

  In particular, when a dirt sensor 21b that detects certain image data is used, a spot (dirt part 3a) to which the dirt (fat, protein, etc.) of the cleaning object 3 is attached has a color tone or a reflection wavelength. Identified by the difference. Therefore, each of the arm portions 19 and 20 is controlled so that the dirt sensor 21b of the spray nozzle 21 searches the surface of the cleaning object 3 thoroughly. Based on the position data of the dirt part 3a obtained by the dirt sensor 21b, each hydraulic pump of the cleaning liquid ejecting apparatus 14 is driven so that the spray nozzle 21 faces the corresponding dirt part 3a substantially perpendicularly. Be controlled. By controlling in this way, the cleaning liquid is directly sprayed locally, so that the cleaning object 3 is not damaged by the cleaning liquid. Further, the cleaning liquid is not used more than necessary, and the apparatus configuration can be made in consideration of the resource environment.

  When a plurality of dirt sensors 21b are fixed, the cleaning liquid ejecting apparatus 14 is controlled based on the position data of the washing dirt portion 3a within the range that each dirt sensor 21b can detect. Further, when the spray nozzle 21 is fixed and disposed on the fixed arm, the cleaning liquid is controlled to be sprayed only from the spray nozzle 21 in the vicinity of the dirt portion 3a specified by the dirt sensor 21b. The By adopting such a configuration, a device configuration with complicated structure and control such as the swinging portions 17 and 18 and the arm portions 19 and 20 is not required, and a simpler configuration can be achieved.

  In the cleaning liquid fixing unit 7, the conveyance unit may be controlled so as to reduce the conveyance speed of the conveyance unit 5 a to be conveyed or to stop the conveyance unit 5 a for a predetermined time. Further, when using a cleaning liquid comprising a fiber-based aqueous cleaning composition containing a nonionic surfactant and a cosolvent, fixing of the cleaning liquid in the cleaning liquid fixing unit 7 is particularly important, so that it is usually used. You may control so that it may differ from the case where the washing | cleaning liquid used is used. Specifically, it is preferable that the transfer speed of the cleaning object 3 is controlled so that the cleaning liquid fixing unit 7 is transferred over the period of 5 to 10 minutes.

  The rough rinsing apparatus 8 is provided with a sensor or the like for reading cleaning information stored in the IC tag, and ejects from the ejection nozzle unit 27 based on cleaning information such as the material, shape, and degree of contamination of the cleaning object 3. The amount of water to be rinsed, the time, the sliding speed of the sliding portion 26, and the like are controlled. By controlling in this way, since the rinsing water is jetted in accordance with the shape and size of the cleaning object 3, it is possible to rinse the cleaning object 3 thoroughly and to reduce the amount of rinsing water to be jetted. be able to. Further, by controlling the amount of water jetted, it is possible to perform rinsing corresponding to customer needs and improve the cleaning quality.

  In the rinsing / dehydrating apparatus 9, a sensor or the like for reading cleaning information stored in the IC tag is disposed, and components such as the housing 28 are controlled as follows. That is, as shown in FIG. 1, first, at the position P <b> 1, the rotation of the cleaning object 3 is controlled so as to be substantially perpendicular to the conveyance path 5. Subsequently, the door portion 28a is rotated and the cleaning object 3 is accommodated in the tank 28b. In such a case, the transfer speed of the transport section 5a, the transfer speed of the housing 28, the rotational speed of the door section 28a, and the like are controlled. From the position P1 to the position P2 and the position 3, the housing 28 and the cleaning object 3 are controlled to be transferred at substantially the same speed while the cleaning object 3 is accommodated in the tank portion 28b. At the same time, at the position P2 and the position P3, the main rinsing and dehydration are controlled.

  In the main rinsing, the water injection device and the drainage device are controlled so that the deaeration device in the dehydration differs depending on the type of the cleaning object 3 and the type of the cleaning liquid. In particular, when a cleaning liquid composed of the above-described aqueous cleaning composition for fibers having a nonionic surfactant and a co-solvent is used, it is preferable that the cleaning object 3 is rinsed 5 to 10 in rinsing water. . For this reason, after the rinsing water is poured from the water pouring device, the water is drained by the draining device after a predetermined time has elapsed. The immersion time is controlled so as to vary depending on the material and size of the cleaning object 3.
