JP7216999B2 - Rotary injection device, rotary injection device assembly, fluid injection device, and injection cleaning method - Google Patents

Description

The present invention relates to techniques applicable to various processes and operations such as cleaning, disinfection, coating, wetting, containing liquid, wetting with liquid, wiping, cooling, heating, and supplying. More specifically, a rotary injection device and a rotary injection device for spraying what can be injected such as gas (including dry gas and moisture content), liquid, steam, mist, powder, granules, granular material, etc. It is about aggregates.

The present invention also relates to a fluid ejecting apparatus mainly composed of the rotary ejecting device and/or the rotary ejecting device assembly.

The present invention further relates to a jet cleaning method implemented using a treatment means such as the fluid jet device described above.

Patent Document 1 below discloses a cleaning device that cleans the surface of an object to be processed by utilizing the fluidity of gas such as clean air. By the way, the object to be treated in this case is simply called an object, and there are various other names such as an object to be sprayed, an object to be dust-removed, an object to be cleaned, and an object to be sprayed.

The cleaning device of Patent Document 1 is capable of cleaning the surface of a thin object stably, with high quality, and with high efficiency, and can be carried out simply and inexpensively. However, since the cleaning device described in this document removes the dust adhering to the thin object with the adhesive roller of the cleaning mechanism, it is necessary to periodically replace the heavily soiled adhesive roller with a new adhesive roller. There was a necessary annoyance. In addition, there is also the problem that the conveying mechanism for conveying the thin object becomes large-scaled.

On the other hand, when the spin nozzle disclosed in Patent Document 2 below is used, it is possible to remove the dust adhering to the thin object by the air jet force. In the case of this spin nozzle dust removal method, unlike the adhesive roller dust removal method (Patent Document 1), there is no troublesome replacement of rollers as described above, so the maintenance burden is reduced.

As for the spin nozzle (also called a pipe nozzle) of Patent Document 2, the injection port at the tip of the nozzle is oriented obliquely with respect to the nozzle rotation axis. In the spin nozzle of Patent Document 2, by adopting such a nozzle structure, the nozzle itself automatically turns along with the air injection. Furthermore, the rotation speed of the spin nozzle in this case depends on the pressure of the air supplied thereto and the air flow rate per unit time. That is, when the air pressure and air flow rate are increased, the spin nozzle rotates at an increased speed, and conversely, when the air pressure and air flow rate are decreased, the spin nozzle rotates at a reduced speed.

The spin nozzle of Patent Document 2 described above leaves some room for improvement. It is like <01> to <04> below.
<01> Since the rotational speed of the spin nozzle depends on the air pressure and air flow rate supplied to it, rotary injection such as high-pressure air injection at low-speed rotation of the nozzle and low-pressure air injection at high-speed rotation of the nozzle Can't take any form. Therefore, it becomes difficult to perform fine dust removal work according to the situation of the object to be dust removed.
<02> The direction of rotation of the spin nozzle is determined by the obliquely oriented orifice at the tip of the nozzle. That is, the spin nozzle only rotates in one direction, such as right rotation only (clockwise) or left rotation only (counterclockwise). This means that the rotation direction of the spin nozzle cannot be switched at any time or at regular intervals. Of course, this also makes it difficult to perform fine dust removal work according to the situation of the object to be dust removed.
<03> When air is jetted from a spin nozzle, the object to be treated is cleaned by the dust removing action of the jetted air. Simply put, this is a dust removal process that uses only jet air. Therefore, it is not possible to deal with stains that are difficult to remove with jet air, and the range of application is limited.
<04> Spin nozzle air injection and nozzle rotation are inseparable. Therefore, air cannot be jetted while the spin nozzle is in a stopped state (non-rotating state), and conversely, it is impossible to stop only the air jetting state while maintaining the spinning state of the spin nozzle. In this type, it is also impossible to set the spin nozzle in a non-rotating state and intensively inject air in a specific direction.
<05> The spin nozzle only injects air as described above. Moreover, in the related technical documents, there is no technical disclosure that the dust removal function is further enhanced by using other means in combination. Therefore, at present, it can be said that there are few technical suggestions and incentives for implementing dust removing means with higher performance.

The rotary injection device according to the present invention has the following effects <11> to <15>.
<11> The fluid ejection tube of the rotary ejection device rotates by a power transmission method in which power from a rotary drive system is received by a transmission component on the outer periphery of the tube. Such a fluid ejection tube is fundamentally different from the conventional one that rotates as the fluid is ejected. Furthermore, the fluid ejection by the fluid ejection tube and the rotation of the fluid ejection tube are independent of each other, and there is no mutual interference between them. That is, the fluid ejection pipe can freely rotate and stop rotating regardless of the condition of the fluid for ejection. The typical operation states that can be freely selected by this fluid injection pipe are: fluid injection in the stopped rotation state, fluid injection in the low speed rotation state, fluid injection in the middle speed rotation state, and high rotation state. For example, fluid injection at In this case, the injection fluid can be freely set to supply a small amount of fluid, supply a medium amount of fluid, supply a large amount of fluid, or the like. Therefore, in the case of the rotary ejection device, various modes can be adopted for the rotation of the fluid ejection tube and the ejection of the fluid, so that advanced and appropriate processing can be performed according to the purpose and situation of the work.
<12> The fluid ejection tube of the rotary ejection device, which rotates by receiving power transmission from the rotation drive system, also differs from the conventional type that rotates with the fluid ejection, and the rotation speed is controlled by the speed control of the rotation drive system. can be accurately controlled, stable rotation can be expected regardless of whether the rotation is continuous or intermittent.
<13> In the case of a fluid ejection tube of a rotary ejection device, in the case of a fluid ejection tube having a contact member attached to the tip of the tube that can come into contact with the object to be ejected (object to be treated), fluid ejection A synergistic effect can also be obtained with the tube and the contact member. For example, when cleaning an object to be processed, the cleaning effect is greatly improved by the combination of the cleaning work by the fluid jetted from the fluid jet pipe and the cleaning work by the contact member. When performing coating, wiping, and other processing operations, the synergistic effect of the sprayed fluid and the cleaning operation can improve workability.
<14> One of the rotary injection devices is simply a transmission part attached to the outer periphery of the fluid injection pipe. Another type of rotary ejection device is one in which a contact member is simply attached to the tip (nozzle portion) side of a fluid ejection tube. Still another type of rotary ejection device is one in which a transmission component or a contact member is simply attached to each of the predetermined portions of the fluid ejection pipe. The rotary injection device thus has fewer components and is simpler in construction, resulting in a generally simpler device construction.
<15> As mentioned above, the number of parts (members) is small and the configuration is simple. Such a rotary injection device is easy to assemble and manufacture. Therefore, in the case of the rotary injection device, it can be provided at a low cost due to the small number of parts, the simple structure, the ease of assembly, the ease of manufacture, and the like.

The rotary injection device assembly according to the present invention has the following effects <16> to <19>.
<16> Since each rotary ejection device in the assembly of rotary ejection devices has a configuration in common with the rotary ejection device described above, the effects of <11> to <15> described above are achieved. There is
<17> In the case of each fluid ejection tube (plurality) in a rotary ejection device assembly, they are grouped together without being dispersed, so handling is more difficult than handling multiple separate and independent single fluid ejection tubes. is also easy.
<18> In the case of a rotary ejection device assembly, since multiple fluid ejection tubes are already arranged, for example, when arranging (laying out) a large number of fluid ejection tubes over a wide area, a large number of single fluid ejections As compared with the case of arranging the pipes in an aligned manner, the arranging operation can be performed easily and quickly.
<19> Regarding the arrangement (layout) of the fluid ejection tubes when creating the assembly of rotary ejection devices, the assembly can be assembled by assuming the ejection tube arrangement (layout) required in subsequent device fabrication. . When this rotary ejector assembly is used, the major steps in manufacturing the fluid ejecting device in which the fluid ejecting tubes form a predetermined arrangement are simplified, so that the manufacturing of the device can be rationalized.

The fluid ejection device according to the present invention has the following effects <20> to <22>.
<20> Since the fluid ejection device comprises the above-described rotary ejection device or the above-described rotary ejection device assembly as a component, the effects of <11> to <15> described above can be obtained. Or it has the effects of <16> to <19> described above.
<21> In a fluid injection device, a rotary injection device or a rotary injection device assembly is arranged in a casing. In this case, the nozzle portion of the rotary injection device is provided with a fluid injection angle with respect to the object (object to be injected) moving in the casing relative to the object. Since it is only necessary to dispose the rotary ejection device or the assembly of rotary ejection devices in the casing while paying attention to the fluid ejection angle of the nozzle portion of the rotary ejection device, the configuration of the main part of the fluid ejection device is simple. In addition, the assembly of the device becomes simple and easy.
<22> Regarding the fluid injection device, if the contact member is attached to the fluid injection pipe (the main member of the rotary injection device) in the casing, the fluid injection action by the fluid injection pipe and the contact action by the contact member are different. Since they are superimposed, they exert a high and strong acting force on the object (the object to be jetted). In the case of such a fluid ejecting apparatus, high-speed processing, shortening of processing time, certainty of processing effect, etc. can be expected in each of the above-described processing.

The injection-type cleaning method according to the present invention has the following effects <23> to <24>.
<23> One of the injection-type cleaning methods involves only a few low-difficulty operations. The main points are: a. rotating the fluid injection pipe of the rotary injection device, b. and c. allowing the object to be injected with the injection fluid to enter the casing from the casing inlet and progress to the casing outlet. Of course, even with just these three simple operations, the object is sufficiently cleaned up. That is, the injection fluid from the nozzle portion of the fluid injection pipe is sprayed onto the object within the casing, and the object is cleaned up by the cleaning action of this spray.
<24> Another jet-type cleaning method performs contact processing on an object using a contact member attached to a fluid jet pipe in addition to the fluid jet processing described above. Incidentally, in the case of only fluid injection processing or only member contact processing, only individual processing results can be obtained. On the other hand, in the case of the method of cleaning the object while synchronizing the fluid jetting process and the member contacting process, [jetting removal action of the jetted fluid + tapping removal action of the contact member + wiping off the contact member Dust removal from the object (dust removal) is dramatically improved by cooperation (synergistic effect) such as removal action]. Along with this, the reliable cleaning treatment of the object is also speeded up. On the other hand, when the suction action inside the casing is added to this, the suction action quickly discharges the spent fluid to the outside of the casing, and the inside of the casing is maintained in a highly clean state, so that the environment inside the casing is kept clean. favorable for processing. Objects are cleaned up to a higher degree under these favorable conditions.

DETAILED DESCRIPTION OF THE INVENTION Embodiments of a rotary ejection device, a rotary ejection device assembly, a fluid ejection device, an ejection cleaning method, and the like according to the present invention will be described with reference to the accompanying drawings. In that order, the rotary injection device will be explained first, the rotary injection device assembly will be explained second, the fluid injection device will be explained third, and the injection cleaning method will be explained fourth. .

In the following rotary injection device, rotary injection device assembly, fluid injection device, etc., which are explained with reference to the drawings, materials or parts and members whose materials are not specifically described are made of metal, plastic, composite material, etc. These have mechanical properties (strength) according to their functions and applications.

The object to be treated (object W to be treated in the figure) in the present invention is simply referred to as an object as described above, as well as an object to be sprayed, an object to be dust-removed, an object to be cleaned, an object to be sprayed, and the like. There are various names such as

In the rotary ejection device illustrated in FIGS. 1 and 2, 11 indicates a fluid ejection pipe and 21 indicates a contact member. Furthermore, 31 denotes a transmission component, and 41 denotes a rotary drive system.

The fluid ejection tube 11 is made of any one of metal, plastic, wood, bamboo, ceramic, glass, stone, cardboard, or a composite material in which two or more of these materials are combined. The fluid ejected through the fluid ejection pipe 11 may be gas (including dry gas or moisture-containing material), liquid, steam, mist, powder, granules, granules, or any of these. It is a mixed fluid consisting of multiple combinations. Therefore, the material of the fluid jet tube 11 is selected to be suitable for the fluid to be handled, that is, to be able to handle the fluid to be used satisfactorily according to the purpose.

One end (the upper end in the drawing) of the fluid ejection pipe 11 has an introduction port 12 as a fluid inflow portion for introducing the fluid, and the other end (the lower end in the drawing) of the fluid ejection pipe 11 has a , a nozzle portion 13 having an injection port (nozzle hole) for injecting the introduced fluid. There is a bent portion between both ends (intermediate portion) of the fluid ejection tube 11, whereby the overall shape of the fluid ejection tube 11 extending from one end to the other end is bent in a substantially doglegged shape. there is

The contact member 21 is made of any one of plant fibers, animal fibers, chemical fibers, fibrous synthetic resins, metal fibers, woven fabrics, non-woven fabrics, cords, threads, etc., or a combination of multiple types thereof. consists of Of course, the contact member 21 may be made of rubber or plastic. Some representative examples of the specific shape structure of the contact member 21 include a shape structure like a long and narrow cylinder, a shape structure like a long and thin cylinder cut open in the vertical direction, and a shape structure like a bundle of strips. There is a shape structure like a broom, a shape structure like a broomstick, a shape structure like a beating part in a beating, a shape structure like a brush part in a brush, and so on. A preferred contact member 21 is a braided cord. Braided cords include square braided cords, flat flat braided cords, round round braided cords, and any of these braided cords can be used as the contact member 21 . A typical example of the braid used as the contact member 21 is a braid made of synthetic resin, but a braid made of vegetable fibers or animal fibers can also be used as the contact member 21 . Of the braided cords, a cylindrical (pipe-shaped) braided cord is more desirable because it can be assembled by being fitted around the outer periphery of the fluid ejection pipe 11 . A synthetic resin round string or the like is attached and fixed to the outer periphery of the fluid ejection pipe 11 by thermal welding. As the contact member 21 made of a braid, one having a disentangled tip is preferred. In the case of the contact member 21 whose tip is defibrated, the tip is in a brush-like state, so that the effect of striking the object W to be processed is extremely high.

The contact member 21 is integrally combined with the fluid ejection pipe 11 by assembling it. More specifically, one end of the contact member 21 is fitted to the outer periphery of the fluid ejection pipe 11 on the one end side (nozzle part 13 side), and the one end of the contact member 21 is fitted with a binding material (thread, string, rubber string). a wire or the like), or one end thereof is tightened and fixed to the outer periphery of the fluid ejection pipe 11 by a ring-shaped metal fitting for tightening, or The contact member 21 is assembled and fixed to the fluid ejection pipe 11 by well-known common means such as fixing one end to the outer peripheral portion of the fluid ejection pipe 11 by welding or adhesive. Conversely, one end of the contact member 21 is fitted into the nozzle portion 13 of the fluid ejection tube 11 and the outer peripheral surface of the one end of the contact member 21 is fixed to the inner peripheral surface of the one end of the fluid ejection tube 11 . Sometimes it is done.

The transmission component 31 is attached to the outer peripheral portion of the fluid ejection pipe 11 as will be described later. The transmission component 31 is usually represented by a transmission wheel (pulley), a gear (gear), or the like. However, in the embodiment of FIGS. 1 and 2, since the non-contact transmission system is adopted as the power transmission system from the rotary drive system 41 to the transmission component 31, the transmission component 31 is also provided with magnets (magnet pieces) for driven use. A transmission wheel is adopted. Of course, such magnetized transmission wheels are well known. By the way, the non-contact transmission system using a magnet is known from Japanese Patent Application Laid-Open Nos. 2002-218735, 2002-211785, and 50-136559. The non-contact transmission system using magnets in the present invention is also technically common to these known techniques. Therefore, the transmission component 31 also has a large number of magnets (magnet pieces, not shown) mounted at predetermined intervals on the peripheral surface and/or the plate surface of the transmission wheel.

A rotary drive system 41 for rotating the fluid injection pipe 11 via the transmission component 31 is as follows with reference to FIGS. 1 and 2. FIG. Two bearing stands 43a and 43b are provided on the base 42X, and the rotating shaft 44X is supported so as to be rotatable forward and backward through the two bearing stands 43a and 43b. A prime mover 45 consisting of a forward and reverse rotatable electric motor (motor) is arranged on the side of a bearing stand 43a on a base 42X, and an output shaft 46 of the prime mover 45 and a rotary shaft 44X form a straight line. The rotary shaft 44X and the output shaft 46 of the prime mover 45 are connected via a coupling 47, which is a shaft joint. A transmission component 48 paired with the transmission component 31 is attached to the outer peripheral portion of the rotating shaft 44X. This transmission component 48 is also composed of a drive wheel for a driving force provided with magnets (magnet pieces).

Other configurations related to the fluid ejection tube 11 with the transmission component 31 will be described in detail with reference to FIG. A through hole 51 is formed through the base 42X in the thickness direction. The fluid ejection pipe 11 is inserted through the through hole 51 of the base 42X and is attached and held at this location so as to rotate forward and backward. More specifically, a bearing member (bearing) 52 interposed between the outer peripheral surface of the fluid ejection pipe 11 and the inner peripheral surface of the through hole 51 or the outer peripheral surface of the fluid ejecting pipe 11 and the inner peripheral surface of the through hole 51 The fluid ejection pipe 11 is rotatably held in the through hole 51 of the base 42X via a set collar 53 or the like that is inserted between the fluid ejection pipe 11 and the surface. By the way, the set collar 53 is publicly known or well-known. On the other hand, on the base 42X, a rotary shaft 44X supported by double bearing stands 43a and 43b so as to rotate forward and backward is located close to one end (upper end in FIG. 2) of the fluid ejection pipe 11 and in contact therewith. are orthogonal. The transmission component 31 attached to the outer peripheral surface of the upper end portion of the fluid injection pipe 11 and the transmission component 48 attached to the outer peripheral surface of the rotating shaft 44X correspond to each other as a pair of transmission components so that power can be transmitted. The output shaft 46 of the prime mover 45 arranged on the side of the bearing stand 43a on the base 42X is aligned with the rotary shaft 44X as described above, and is coupled to the rotary shaft 44X through the coupling 47. It is The upper surface of the base 42X on which the required components are mounted is surrounded by a duct-shaped cover 54X. The cover 54X is detachable from the base 42X. However, the inside of the upper surface of the base 42X covered with the cover 54X is isolated from the outside and airtight.

In the illustrated example above, the required fluid is supplied into the cover 54X that covers the upper surface of the base 42X, and the fluid is ejected through the rotary ejection device (fluid ejection pipe 11). In this case, various fluids are selected according to the purpose and application of the rotary injection device. Basically, dry gas with a humidity of less than 50%, low humidity gas with a humidity of 50% to less than 80%, high humidity gas with a humidity of 80% or more, water vapor, mist, liquid, etc. can be used as a fluid for As a typical example, in the rotary injection device illustrated in FIGS. 1 and 2, clean air is employed as the fluid and supplied into the cover 54X. Therefore, a fluid supply system 55 for supplying fluid is pipe-connected to the cover 54X. As such a fluid supply system 55, for example, one having an air compressor, an air filter mechanism (air purifier), etc. in a piping system is adopted, and clean air is supplied into the cover 54X through it. The cleanliness of the air supplied at this time is set, for example, within the range of Classes 1 to 9 of International Standard (ISO) 14644-1.

1 and 2, when the prime mover 45 is driven and rotated forward or backward, the rotation is the output shaft 46→coupling 47→rotating shaft 44X→transmission part 48. → It is transmitted like the transmission component 31, and thereby the fluid injection pipe 11 rotates forward or backward. At this time, since the required fluid is continuously or intermittently supplied into the cover 54X via the fluid supply system 55, the supplied fluid flows into the pipe 11 from the inlet 12 of the fluid injection pipe 11. Then, it is jetted from the nozzle portion 13 of the pipe 11 . Therefore, for example, when the film-like or sheet-like object W to be processed, which is schematically shown in FIG. It is sprayed onto the surface of the object W, thereby treating the surface of the object W to be treated. As a specific example, when the fluid ejected from the fluid ejection tube 11 is a cleaning gas such as clean air or a cleaning liquid such as clean water, the fluid adheres to the surface of the object W to be processed. Dust and various stains on the surface are removed or blown away by the physical jetting cleaning action of the jetting fluid for the cleaning process. The object W to be treated is finished in a clean surface state by receiving such injection cleaning treatment.

A contact member 21 is attached to the nozzle portion 13 side of the fluid ejection pipe 11 described above. The contact member 21 rotating in this way contacts the surface of the object W to be processed in a dynamic state with a cleaning action. That is, while rotating, the surface of the processing object W is hit, rubbed, and wiped. In the case of the processing object W subjected to the beating action, rubbing action, and wiping action of the contact member 21, dust and dirt adhering to the surface are thereby removed or flipped off. Therefore, the surface of the object W to be processed is kept clean even by this contact cleaning process.

In the above-described treatment in which the injection cleaning treatment and the contact cleaning treatment work in a superimposed manner, the surface of the object W to be treated is cleaned while undergoing this dual treatment at the same time. This is because two different dust removal and cleaning forces act synchronously, such as the physical action of jetting and the physical action of contact. increase. Therefore, the surface of the object W to be treated can be finished to a higher degree of cleanliness as a result of the synergistic effect of the superposition of the injection cleaning treatment and the contact cleaning treatment.

Another application of the rotary injection device illustrated in FIGS. 1 and 2 is to apply a liquid to the surface of an object W to be processed. In this case, instead of gas, application liquid is supplied to the fluid ejection pipe 11 from the fluid supply system 55 , and is ejected from the nozzle portion 13 of the fluid ejection pipe 11 . The liquid ejected from the fluid ejection pipe 11 in this way spreads over the surface of the object W to be processed while being sprinkled by the rotation of the pipe 11 . On the other hand, the contact member 21 rubs the surface of the object W to be processed and smoothly applies the injection liquid to the surface. Therefore, when the coating liquid is ejected from the fluid ejection pipe 11 and applied to the surface of the object W to be processed, the quality and efficiency of the work during the application are high.

Manufacture of a fluid ejection device for cleaning (cleansing) an object to be processed, mainly using the rotary ejection device illustrated in FIGS. 1 and 2, or production of a fluid ejection device used for other purposes. When manufacturing, a casing is used for arranging a single, a plurality of, or a large number (for example, three or more) of the rotary injection devices. The interior of the casing in this case is a vacuum-suction type chamber, and the chamber has an inlet and an outlet for entering and leaving the processing object traveling in one direction.

Four bearing stands 43a, 43b, 43c, and 43d are provided on the base 42Y, which is longer than the previous example. It is A prime mover 45 consisting of a forward and reverse rotatable electric motor (motor) is arranged on the bearing stand 43a side on the base 42Y, and the output shaft 46 of the prime mover 45 and the rotary shaft 44Y form a straight line. The rotary shaft 44Y and the output shaft 46 of the prime mover 45 are connected through a coupling 47, which is a shaft joint, in the same manner as in the previous example. On the other hand, a plurality of transmission parts 48 paired with each transmission part 31 are attached to the outer peripheral portion of the rotary shaft 44Y at predetermined intervals. Each transmission component 48 in this case also consists of a transmission wheel for a driving force provided with the magnets (magnet pieces) described above.

Another configuration related to the fluid ejection pipe 11 with the transmission component 31 will be described in detail with reference to FIGS. 3 and 4. FIG. A plurality of (five) through holes 51 are formed in the base 42Y so as to pass through the base 42Y in the thickness direction. Each through hole 51 in this case has the following configuration. When the front and rear sides of the base 42Y in FIG. 3 are used as references, the two through holes 51 are near the front edge of the base 42Y, and the remaining three through holes 51 are near the rear edge of the base 42Y. That is, the five through-holes 51 are arranged in a zigzag manner with reference to the front and rear side edges of the base 42Y, near the rear edge, near the front edge, near the rear edge, near the front edge, and near the rear edge. It is Each fluid ejection pipe 11 is attached to and held by these portions so as to be freely rotatable forward and backward while penetrating through each through hole 51 of the base 42Y. Specifically, as in the previous example, a bearing member (bearing) 52 interposed between the outer peripheral surface of the fluid ejection pipe 11 and the inner peripheral surface of the through hole 51 , and the outer peripheral surface of the fluid ejecting pipe 11 and the inner peripheral surface of the through hole 51 The fluid ejection pipe 11 is rotatably held in the through hole 51 of the base 42Y through the set collar 53 and the like inserted between the peripheral surface and the above-described set collar 53 . On the other hand, on the base 42Y, a rotating shaft 44Y supported for forward and reverse rotation via respective bearing stands 43a to 43d is close to one end (upper end in FIG. 3) of each fluid ejection pipe 11. are orthogonal to these. Each transmission component 31 attached to the outer peripheral surface of the upper end portion of each fluid ejection pipe 11 and each transmission component 48 attached to the outer peripheral surface of the rotating shaft 44Y are paired as transmission components so that power can be transmitted. It corresponds. The output shaft 46 of the prime mover 45 arranged on the side of the bearing stand 43a on the base 42Y is aligned with the rotating shaft 44Y and is connected to the rotating shaft 44Y through the coupling 47, as in the previous example. there is The upper surface of the base 42Y on which the required components are mounted is surrounded by a duct-like cover 54Y longer than in the previous example. The cover 54Y in this case is also detachable from the base 42Y. In FIGS. 3 and 4, the inside of the upper surface of the base 42Y covered with the cover 54Y is also in an airtight state, being cut off from the outside, as in the previous example.

3 and 4, the required fluid is supplied to the inside of the cover 54Y on the base 42Y, and the fluid is ejected through each fluid ejection pipe 11. FIG. In this case, various fluids are also selected according to the purpose and application of the rotary ejection device assembly. As in the previous examples, the fluids that can be used in the assembly of rotary injection devices shown in FIGS. Wet gas, water vapor, mist, liquid, etc. 3 and 4, when clean air is employed as the required fluid, the clean air is supplied into the cover 54Y. Furthermore, in this case, when the fluid supply system 55 for supplying fluid connected to the cover 54Y is provided with an air compressor and an air filter mechanism (air purifier) as described above, for example. through which clean air is supplied into the cover 54Y. The air cleanliness of clean air is also set within the range of Classes 1 to 9 of International Standard (ISO) 14644-1.

3 and 4, when the prime mover 45 is set in the operating state and is rotated forward or backward, the rotation of the prime mover 45 changes from the output shaft 46 to the coupling 47. →rotating shaft 44X→plurality of transmission parts 48→plurality of transmission parts 31, along with which each fluid ejection pipe 11 rotates forward or backward. At this time, since the required fluid is continuously or intermittently supplied into the cover 54X via the fluid supply system 55, the supplied fluid is supplied from the introduction port 12 of each fluid injection pipe 11 into each pipe 11. and jetted from the nozzle portion 13 of each pipe 11 . Therefore, for example, when the film-like or sheet-like object W to be processed, which is schematically shown in FIG. The surface of the object W to be treated is sprayed, and the surface of the object W to be treated is thereby treated. As a specific example, when the fluid ejected from the fluid ejection tube 11 is a cleaning gas such as clean air or a cleaning liquid such as clean water, the fluid adheres to the surface of the object W to be processed. Dust and various types of contaminants on the surface are removed or blown away by the physical jet cleaning action of the jet fluid for the cleaning process. The object W to be treated is finished in a clean surface state by receiving such jet cleaning treatment. On the other hand, the contact member 21 rubs the surface of the object W to be processed and smoothly applies the injection liquid to the surface. Therefore, when the coating liquid is ejected from the fluid ejection pipe 11 and applied to the surface of the object W to be processed, the quality and efficiency of the work during the application are high.

As is clear from the above description, the assembly of rotary jetting devices illustrated in FIGS. 3 and 4 differs from the preceding examples in FIGS. 1 and 2 in that the number of rotary jetting devices is large. Although different, it is not different from the rotary injector illustrated in FIGS. 1 and 2 in terms of basic matters such as its application and purpose of use, and is substantially the same as the previous example. Therefore, in the case of the rotary injection device assembly illustrated in FIGS. 3 and 4, all of the technical matters described in the previous examples can be adopted within the scope of technical compatibility.

A specific example of a fluid ejection device according to the present invention is schematically shown in FIG. The fluid injection device illustrated in FIG. 5 is equipped with the rotary injection device assembly ZL already described (FIGS. 3 and 4) inside a casing 61 having an inlet 62 and an outlet 63 . More specifically, a pair of upper and lower rotary type rollers are placed on the upper side and the lower side of the reference plane (moving plane of the object to be processed W) in the casing 61 between the inlet 62 and the outlet 63 . An injection device assembly ZL is arranged. In this case, the vertically rotating injection device assembly ZL is mounted and supported at a predetermined position within the casing 61 by conventional means using supporting members, mounting members, mounting metal fittings, and the like. For example, both ends of the base 42Y and the cover 54Y of each rotary injection device assembly ZL are fixed to the inner surfaces of both side walls of the casing 61 by well-known mounting means. It can be said that the vertically rotating injection device assembly ZL fixed to the inner surfaces of both side walls of the casing 61 extends across the inner surfaces of the both side walls of the casing 61 . In the case of each rotary ejector assembly ZL installed inside the casing 61, the tip of the fluid ejection tube 11 is close to the reference plane inside the casing 61, but does not come into contact with the reference plane. On the other hand, the tip portion of the contact member 21 contacts the reference surface with a surplus portion that covers the reference surface.

Although the casing 61 described above is constructed as a whole, depending on the case, it may be composed of a combination or assembly of a plurality of divided parts, such as upper and lower halves or upper and lower front and rear quarters. In any of these cases, the casing 61 can be partially or wholly disassembled as necessary for work monitoring, maintenance, inspection, or the like.

In the fluid injection device of FIG. 5, a well-known suction device 64 mainly composed of a suction pump is provided on the lower side of the casing 61 . The suction device 64 is for sucking the internal air inside the casing 61 and discharging it to the outside of the casing 61 . Therefore, the suction port of the suction device 64 communicates with the inside of the casing 61 , and the discharge port of the suction device 64 communicates with the exhaust processing section outside the casing 61 . Incidentally, when the fluid injection device in FIG. 5 is for cleaning or dust removal, the suction device 64 in this case is a cleaner equipped with a suction pump, that is, a dust collector known as an electric vacuum cleaner. There is also

In the fluid injection apparatus of FIG. 5, a guide portion 65 for guiding the object W to be processed toward the inlet 62 is provided at the front stage of the casing 61 on the side of the inlet 62 . A first dust-removing roller 66 and a second dust-removing roller 67 for the object W to be processed in the casing 61 are provided in the subsequent stage. Of these, the guide portion 65 is provided with guide rollers, for example. The pair of upper and lower first dust removing rollers 66 is made of, for example, resin or rubber having a dust-adhesive surface. Specific materials for the first dust roller 66 include butyl-based or urethane-based resins or rubbers, or silicone-based resins or rubbers. The pair of upper and lower second dust removing rollers 67 is, for example, a core shaft roller with a tearable adhesive sheet wound thereon. Therefore, the surface of the second dust removing roller 67 is sticky. The object to be treated W coming out of the casing 61 from the casing outlet 63 passes between the pair of upper and lower first dust removing rollers 66 while contacting them. The dust-removing roller 66 in contact with the surface of the object removes dust and the like from the surface of the object to be processed by the adhesive force of the surface. The first dust removing roller 66 also has a function of pulling out the object W to be processed from the inside of the casing 61 to the outside of the casing 61 . A second dust removing roller 67 is in contact with the pair of upper and lower dust removing rollers 66, respectively. The second dust-removing roller 67 removes dust adhering to the first dust-removing roller 66 by adhesion therefrom. That is, the second dust removing roller 67 can be said to be for cleaning the first dust removing roller 66 . As a result, the dust removing function of the first dust removing roller 66 is maintained for a long time (long term). In the fluid ejecting apparatus of FIG. 5, a pair of upper and lower neutralizers 68 are also arranged at the front stage position of the casing inlet 62 and the rear stage position of the casing outlet 63, respectively. As an example, the static eliminator 68 consists of a well-known product called a static eliminator brush. This well-known static eliminator 68 is formed by arranging metal wires made of tungsten or a tungsten alloy in a reed pattern or a comb shape. Of course, the static eliminator 68 may also be made of a static eliminator metal other than tungsten or a tungsten alloy.

In the fluid ejecting apparatus of FIG. 5, the object W to be processed undergoes the following processes while moving from the left side to the right side of the drawing. Initially, the object W to be treated is neutralized when it passes between the two neutralizers 68 on the casing inlet 62 side. That is, the object W to be processed is instantaneously neutralized by the front-stage static eliminators 68 to neutralize the static electricity that is charged thereon. Next, the object W to be processed enters the casing 61 . Furthermore, the object W to be processed advances along the reference plane (the moving surface of the object W to be processed) within the casing 61, and is subjected to a cleaning process for cleanup here. At this time, in the casing 61, each fluid ejection pipe 11 of the vertically rotating ejection device assembly ZL rotates while ejecting an ejection fluid (for example, clean air) from each nozzle portion 13. As shown in FIG. At this time, the contact member 21 attached to the nozzle portion 13 side of each fluid ejection tube 11 also rotates together with the fluid ejection tube 11 . The object to be processed W traveling in the casing 61 in such an operating state receives the ejected fluid ejected from the nozzle portion 13 of each fluid ejecting pipe 11 on both sides thereof, and at the same time, is hit, rubbed, wiped, etc. by each contact member 21. received on both sides. The object W to be processed is cleaned up by the cleaning action of spraying the jet fluid and the cleaning action of the contact member 21 such as beating, rubbing, and wiping. At this time, the internal air inside the casing 61 is sucked by the suction device 64 and discharged to the outside of the casing 61, so that dust and the like circulate inside the casing 61 and adhere to the object W to be processed again. No inconvenience occurs. After leaving the casing 61, the object W cleaned up in the casing 61 is subjected to dust removal by the dust removal roller 66 and static elimination by both static elimination bodies 68 in the latter stage.

The jet cleaning treatment using the fluid ejecting apparatus of FIG. 5 is also one of the embodiments of the jet cleaning treatment method according to the present invention. Therefore, the embodiment of the jet cleaning method according to the present invention will be omitted by referring to the above description regarding the fluid jet device of FIG.
