  The present invention has been made in view of the above-described problems, and provides a cylindrical body cleaning device and a cylindrical body cleaning method capable of continuously transporting a cylindrical body and efficiently cleaning the cylindrical body. And

  The cleaning liquid for cleaning the substantially cylindrical tubular body is stored, the cleaning tank for ultrasonically cleaning the cylindrical body immersed by the ultrasonic vibration means, and at least the cleaning liquid attached to the cylindrical body is removed. A cylindrical body cleaning apparatus and a cylindrical body cleaning method, comprising: a cleaning liquid removing unit; and at least the cleaning tank; and a transport unit configured to transport the cylindrical body in the order of the cleaning liquid removing unit. A support base that supports both ends in the longitudinal direction of the cylindrical body in which the longitudinal direction of the cylindrical body is substantially horizontal, and a short direction of the cylindrical body with respect to a transport direction in which the cylindrical body is transported A plurality of the support bases arranged so as to substantially coincide with each other, provided with a substantially annular annular feed portion that permits connection at a predetermined interval in the transport direction, and a drive unit that circulates and drives the annular feed portion. It is characterized by.

The cleaning liquid removing means may be a means for removing the cleaning liquid with pressurized air, a means for removing the cleaning liquid with hot air, a means for removing the cleaning liquid by natural drying, or the like.
The conveying means can be a chain or belt that circulates and conveys the cylindrical body, or a crane that grips and conveys the cylindrical body.
The annular feeding portion can be a substantially annular roller chain or a substantially annular belt.

According to the present invention, the cylindrical body can be continuously conveyed and the cylindrical body can be efficiently cleaned.
Specifically, when the longitudinal direction of the cylindrical body is substantially aligned with the transport direction, the cylindrical body cleaning device is likely to increase in size in the substantially vertical direction or in the substantially horizontal direction, and in the cleaning tank. The number of cylindrical bodies that can be immersed tends to decrease.

  On the other hand, the cylindrical body cleaning device and the cylindrical body cleaning method perform cleaning so that the short direction of the cylindrical body whose longitudinal direction is substantially horizontal and the transport direction are substantially orthogonal to each other, so that the cleaning tank It is possible to transport and immerse more cylindrical bodies in the inside, and to reduce the size of the apparatus in the substantially vertical direction.

  Further, since the cylindrical body is transported in the order of the cleaning tank and the cleaning liquid removing means by the circulation feeding unit, the cylindrical body cleaning device and the cylindrical body cleaning method include cleaning of the cylindrical body and cleaning liquid attached to the cylindrical body. The removal of the cleaning liquid adhering to the preceding cylindrical body and the cleaning of the subsequent cylindrical body can be performed simultaneously. Thereby, a cylindrical body washing | cleaning apparatus and a cylindrical body washing | cleaning method can wash | clean a cylindrical body efficiently while conveying a cylindrical body continuously without interruption.

  In addition, for example, a crane for placing the cylindrical body on the support base and a crane for unloading the cylindrical body from the support base can be configured separately by the transport means. For this reason, the cylindrical body cleaning device and the cylindrical body cleaning method are more suitable for the cylindrical body that has been cleaned of oil adhering to the crane or the like than when the cylindrical body is loaded and unloaded with the same crane. It can prevent adhesion.

Thereby, the cylindrical body cleaning device and the cylindrical body cleaning method not only efficiently clean the cylindrical body and remove the cleaning liquid, but also can reliably clean the cylindrical body.
Therefore, the cylindrical body cleaning device and the cylindrical body cleaning method can transport the cylindrical body continuously without interruption and can clean the cylindrical body more efficiently and reliably.

  As an aspect of the present invention, a pair of base portions for placing both ends of the cylindrical body in the longitudinal direction on the support base and a gap larger than an outer diameter of the cylindrical body are separated from the short side of the base portion. And an upright portion standing from both ends of the direction.

By this invention, the cylindrical body washing | cleaning apparatus can wash | clean the outer surface of a cylindrical body uniformly.
Specifically, for example, in the case of a support base that holds both ends of the cylindrical body, there is a risk that the portion of the cylindrical body that contacts the support base will be insufficiently cleaned.
On the other hand, the cylindrical body cleaning device can roll between the upright portions in the cleaning liquid by forming the support base with the base portion and the upright portion. It can be washed evenly.

Thereby, the cylindrical body cleaning apparatus not only efficiently cleans the cylindrical body and removes the cleaning liquid, but also more reliably cleans the surface of the cylindrical body.
Therefore, the cylindrical body cleaning device can transport the cylindrical body continuously without interruption and can clean the cylindrical body more efficiently and reliably.

Further, as an aspect of the present invention, a pressurized fluid supply unit that supplies pressurized fluid to the cleaning tank is provided, and the cylindrical body is carried out to the cleaning tank while being connected to the pressurized fluid supply unit. A fluid ejection portion that ejects the fluid toward the liquid surface of the cleaning liquid in the vicinity of the position where the cleaning liquid is present.
The pressurized fluid may be a cleaning liquid, a regenerated cleaning liquid from which impurities such as oil and dust are removed from a cleaning liquid overflowing from the cleaning tank, or air.

According to the present invention, it is possible to prevent floating impurities such as oil floating on the liquid surface of the cleaning liquid from adhering to the cylindrical body carried out from the cleaning liquid.
Specifically, the liquid ejected from the fluid ejection section can make the liquid level of the cleaning liquid in the vicinity of the position where the cylindrical body is carried out, and the floating impurities such as oil floating on the liquid level of the cleaning liquid The cylindrical body can be pushed away to the side where it is carried into the cleaning tank.

  In other words, the cylindrical body cleaning apparatus can prevent floating impurities such as oil floating on the liquid surface of the cleaning liquid from drifting near the position where the cylindrical body is carried out. For this reason, when the cylindrical body is carried out from the cleaning liquid, the cylindrical body cleaning apparatus can prevent the floating impurities from adhering to the cylindrical body.

Furthermore, for example, when the cleaning liquid is used for the pressurized fluid, the cylindrical body cleaning device can make the state of the cleaning liquid near the position where the cylindrical body is carried out better. Thereby, the cylindrical body washing | cleaning apparatus can prevent the washing | cleaning defect of a cylindrical body.
Accordingly, the cylindrical body cleaning apparatus can efficiently clean the cylindrical body by preventing the floating impurities from adhering to the cylindrical body by the pressurized fluid supply means and the fluid ejection part.

  Further, as an aspect of the present invention, the apparatus includes a pressurized cleaning liquid supply unit that supplies the pressurized cleaning liquid to the cleaning tank, and is connected to the pressurized cleaning liquid supply unit in the cleaning tank and is immersed in the cleaning liquid. An internal cleaning unit that ejects the cleaning liquid toward the inner surface of the cylindrical body can be provided.

According to the present invention, the cylindrical body cleaning device can reliably clean the inner surface of the cylindrical body.
Specifically, since the conveyance direction of the cylindrical body and the short direction of the cylindrical body substantially coincide with each other, it is difficult to expect the flow of the cleaning liquid due to the conveyance inside the cylindrical body. For this reason, when carrying out a cylindrical body from a washing | cleaning liquid, there exists a possibility that the oil component, dust, etc. in a washing | cleaning liquid may adhere to the inner surface of a cylindrical body. Further, since the vibrations by the ultrasonic vibration means are difficult to be transmitted to the cleaning liquid inside the cylindrical body, there is a possibility that surface residues such as oil and dust attached to the inner surface of the cylindrical body may not be completely removed. .

  Therefore, the pressurized cleaning liquid supply means and the internal cleaning unit allow the cylindrical body cleaning device to clean the inner surface of the cylindrical body by the jetting pressure of the cleaning liquid and to actively flow the cleaning liquid inside the cylindrical body. it can. For this reason, the cylindrical body cleaning device prevents the removed surface residue from staying inside the cylindrical body, and the removed surface residue is removed when the cylindrical body is carried out from the cleaning liquid. Can be prevented from adhering to the inner surface.

Furthermore, by providing the internal cleaning unit in the cleaning tank, the cylindrical body cleaning device can simultaneously perform the continuous conveyance of the cylindrical body and the cleaning of the inner surface of the cylindrical body.
Accordingly, the cylindrical body cleaning device can more reliably clean the inner surface of the cylindrical body and more efficiently transport the cylindrical body by the pressurized cleaning liquid supply means and the internal cleaning section.

  In addition, as an aspect of the present invention, the cylinder includes a brush portion in which a plurality of linear members are fixed, and a brush moving means that moves the brush portion in a predetermined direction, and the brush portion is immersed in the cleaning liquid. The cleaning tank can be provided in contact with the outer surface of the body.

The brush part may be a brush part in which a plurality of linear materials are fixed so as to stand on a substantially flat plate, or a brush part in which a plurality of linear materials are fixed radially outward on a substantially cylindrical body. Can do.
The predetermined direction can be a longitudinal direction of the cylindrical body, a lateral direction of the cylindrical body, or a rotational direction that rotates about a substantially horizontal rotational axis.

  According to this invention, the surface residue adhering to the outer surface of the cylindrical body that could not be removed by ultrasonic cleaning can be reliably removed by the brush portion that is movable in a predetermined direction. For this reason, the cylindrical body washing | cleaning apparatus can wash | clean the outer surface of a cylindrical body reliably.

Furthermore, by providing the brush portion in the cleaning tank, the cylindrical body cleaning device can simultaneously perform the continuous conveyance of the cylindrical body and the cleaning of the outer surface of the cylindrical body.
Therefore, the cylindrical body cleaning device can more reliably clean the outer surface of the cylindrical body and more efficiently transport the cylindrical body by the brush portion and the brush moving means.

Moreover, as an aspect of the present invention, a portion of the support base on which the cylindrical body is placed can be provided with a concave portion that is recessed with a size smaller than the outer diameter of the cylindrical body.
The recess may be a substantially V-shaped recess, a substantially U-shaped recess, or the like.

According to the present invention, the cylindrical body can be prevented from falling from the support base, and the cylindrical body can be more easily carried into and out of the support base.
Specifically, for example, in the case of a support base that regulates the rolling of the cylindrical body with an interval larger than the outer diameter of the cylindrical body, the support base immersed in the cleaning liquid together with the cylindrical body changes its inclination. However, when it is carried out of the washing tank, the cylindrical body rolls on the support base. At this time, since the support base supports the vicinity of both ends of the cylindrical body, when the cylindrical body rolls so that the longitudinal direction substantially coincides with the diagonal line of the support base, one end of the cylindrical body becomes one of the ends. There is a risk of falling from the support.

  Therefore, the cylindrical body cleaning device is provided with a change in the angle of the support base by fitting the rolled cylindrical body into the concave portion by providing the concave portion in the portion on the support base where the cylindrical body is placed. While being able to prevent a cylindrical body falling, the position of the cylindrical body mounted on the support stand can be specified easily.

For this reason, for example, when the support base is carried out of the cleaning tank, the cylindrical body cleaning device can easily carry out the cylindrical body from the support base by a crane or the like.
Therefore, the cylindrical body cleaning apparatus can prevent the cylindrical body from falling from the support base and can transport the cylindrical body more efficiently by providing the recess.

  Further, as an aspect of the present invention, the cleaning liquid removing means is inserted into the cylindrical body, and an inner surface removing portion that blows air toward the inner surface of the cylindrical body, and interlocked with the inner surface removing portion. The outer surface removing unit that ejects air toward the outer surface of the cylindrical body, and the air supply unit that supplies the air to the inner surface removing unit and the outer surface removing unit.

  According to this invention, the cleaning liquid adhering to the inner surface and the outer surface of the cylindrical body carried out from the cleaning tank can be simultaneously removed. For this reason, even if the cylindrical body washing | cleaning apparatus is a cylindrical body which has an inner and outer surface, it can remove a cleaning liquid efficiently.

  Further, as an aspect of the present invention, the cleaning liquid overflowing from the cleaning tank is stored, an impurity separation tank for separating impurities from the cleaning liquid, and a regenerated cleaning liquid from which the impurities are separated in the impurity separation tank And a regenerating liquid supply means for supplying to the liquid.

The impurities can be oil, iron powder, dust, or the like.
The regeneration liquid supply means may be a pressurized fluid supply means and / or a pressurized cleaning liquid supply means described above, or a supply means different from the pressurized fluid supply means or the pressurized cleaning liquid supply means.

By this invention, the cylindrical body washing | cleaning apparatus can reuse the washing | cleaning liquid which overflowed from the washing tank without waste with simple structure.
Specifically, in the impurity separation tank, by supplying a regeneration cleaning liquid from which impurities such as oil are separated to the cleaning tank, the cylindrical body cleaning device reuses the cleaning liquid overflowing from the cleaning tank without waste, By actively replacing the cleaning liquid in the cleaning tank, impurities can be prevented from staying in the cleaning liquid in the cleaning tank.

  Further, for example, when the regenerative liquid supply means is the above-described pressurized fluid supply means or pressurized cleaning liquid supply means, the regenerative cleaning liquid can be supplied to the cleaning tank via the fluid ejection part or the internal cleaning part. The apparatus can simultaneously perform the circulation of the cleaning liquid and the cleaning of the inner surface of the cylindrical body. For this reason, the cylindrical body cleaning apparatus can circulate the cleaning liquid more efficiently without waste.

In addition, for example, compared with the case where the cleaning liquid overflowing from the cleaning tank is vaporized and evaporated to obtain the regenerated cleaning liquid, the cylindrical body cleaning apparatus can obtain the regenerated cleaning liquid with a simple configuration. The size can be reduced and the cost can be reduced.
Therefore, the cylindrical body cleaning apparatus can reuse the cleaning liquid overflowing from the cleaning tank with a simple configuration without waste by the impurity separation tank and the regenerating liquid supply means, and can clean the cylindrical body more efficiently. .

As an aspect of the present invention, the impurity separation tank can be provided with an oil skimmer that removes oil floating on the liquid surface in the stored cleaning liquid.
According to the present invention, for example, the cylindrical body cleaning device can remove the oil content in the impurity separation tank with a simpler structure than when the oil content is separated by vaporizing and evaporating the cleaning liquid overflowing from the cleaning tank. .

  According to the present invention, it is possible to provide a cylindrical body cleaning apparatus and a cylindrical body cleaning method capable of continuously transporting a cylindrical body and cleaning the cylindrical body efficiently.

And a slide rod 38 for moving the plate 37 in the width direction Y.

The actuator 33 is configured such that the slide rod 38 and the plate 37 move in the width direction Y by the compressed air supplied from the air compressor 39.
The inner blow pipe 34 has an outer diameter smaller than the inner diameter of the inflator pipe P and is formed in a substantially cylindrical shape longer than the length of the inflator pipe P in the longitudinal direction.

  The inner surface blow pipe 34 is arranged so that the central axis extending in the longitudinal direction thereof is substantially coaxial with the central axis extending in the longitudinal direction of the inflator pipe P, and the vicinity of the other end located outside the surrounding wall 32 is disposed in the actuator. It is fixed to 33 plates 37. The other end of the inner surface blow pipe 34 located outside the surrounding wall 32 is connected to an air compressor 39.

  The outer surface blow hose 35 is a substantially cylindrical flexible hose, the opening of one end being arranged toward the substantially center of the inflator pipe P placed on the support base 31, and the other end connected to the air compressor 39. doing.

  Further, as shown in FIG. 8, the drying unit 40 includes a plurality of sprocket pairs 41 that are rotationally driven by a drive motor (not shown), a substantially annular roller chain 42 that meshes with the sprocket pairs 41, and a roller chain 42. A plurality of support bases 43 that are fixed and allow placement of the inflator pipe P and a drying box 44 that surrounds a predetermined length range in the transport direction X are configured.

Note that the sprocket pair 41 and the roller chain 42 have the same configuration except that the sprocket pair 111 and the roller chain 112 in the first cleaning unit 10 are different in arrangement, and thus detailed description thereof is omitted.
The support base 43 is the same as the support section 115 of the first cleaning section 10 described above except that the support base 43 is formed in a support section (not shown) according to the outer shape of the inflator pipe P. Detailed description is omitted because of the configuration.

  The drying box 44 has a length in the transport direction X that surrounds the plurality of support bases 43 in the transport direction X, and has a hot air introduction port 44a that introduces warm air from a hot air machine (not shown) into the interior. Yes.

  Next, using the cylindrical body cleaning apparatus 1 having such a configuration, the cleaning liquid CF circulating while separating oil and the like is used to clean the inflator pipe P conveyed by the first crane 5 to remove surface residues. The cylindrical body cleaning method will be described in detail.

First, the cylindrical body cleaning apparatus 1 operates the transport mechanism unit 110 in the transport direction X in advance, and supervises the cleaning liquid CF heated by the heater of the first cleaning unit 10 by about 60 degrees by the vibration element 122. Apply sonic excitation.
Further, the cylindrical body cleaning apparatus 1 operates the oil skimmer 52 and the regenerated liquid supply unit 60 of the oil separation unit 50, and supplies the cleaning liquid CF in the recovery storage tank 51 to the ejection unit 150 as the regenerated cleaning liquid.

  At this time, since the liquid level in the vicinity of the upper part of the jet part 150 is undulated by the regenerated cleaning liquid jetted from the jet part 150, the cleaning liquid CF in the cleaning tank 120 floats on the liquid surface Fo due to the difference in specific gravity with the cleaning liquid CF. At the same time, the oil flows into the oil separation unit 50 from the washing tank 120 through the outlet path 121 and the outlet pipe 2.

  The cleaning liquid CF that has flowed into the oil separation unit 50 is stored in the recovery storage tank 51 and is separated in the recovery storage tank 51 into the cleaning liquid CF and the floating oil Fo in which the oil has floated due to the difference in specific gravity. At this time, dust such as iron powder contained in the cleaning liquid CF of the recovery storage tank 51 is deposited on the bottom surface of the recovery storage tank 51 due to a difference in specific gravity with the cleaning liquid CF.

  The floating oil Fo in the collection storage tank 51 is discharged from the collection storage tank 51 by adhering to the adsorption belt 52a of the oil skimmer 52 together with the cleaning liquid CF, and is also scraped out of the adsorption belt 52a by the scraper 52b. It is discharged to the first section 54.

  The oil containing the cleaning liquid CF discharged to the first section 54 of the separation tank 53 is further separated into the cleaning liquid CF and the floating oil Fo due to the specific gravity difference inside the first section 54. The floating oil Fo accumulated in the first section 54 is discharged to the oil collection container 56 (see FIG. 3) via the oil discharge pipe 54a.

  On the other hand, the cleaning liquid CF from which the oil component has been separated in the first compartment 54 flows into the second compartment 55 via the space below the partition plate 53a, and when a certain amount or more is stored in the second compartment 55, the discharge pipe 55a. It is discharged to the collection storage tank 51 via

  In this way, the cleaning liquid CF overflowing from the cleaning tank 120 is separated and removed by the oil separation unit 50, and is supplied to the cleaning tank 120 through the regenerated liquid supply unit 60 and the jet unit 150 as a regenerated cleaning liquid. As shown in FIG. 2, when the first crane 5 holding the inflator pipe P reaches the first washing unit 10, the body washing apparatus 1 lowers the first crane 5 and releases the inflator pipe P to provide a support base. The inflator pipe P is placed in the recess 116 a of 113.

  When the inflator pipe P is placed on the support base 113, the transport mechanism 110 moves the inflator pipe P substantially horizontally in the transport direction X, and then supports it while tilting the edge on the transport direction X side downward. The table 113 is moved toward the cleaning tank 120, and the inflator pipe P is immersed in the cleaning liquid CF. At this time, the inflator pipe P rolls as the angle of the support base 113 changes, as shown in part A of FIG. 2, escapes from the recess 116 a of the support part 115, and the base part 116 and the upright part on the lower side 117.

  In addition, since the cleaning liquid CF is ultrasonically vibrated by the vibration element 122 inside the cleaning tank 120, the inflator pipe P immersed in the cleaning liquid CF is subjected to ultrasonic cleaning while removing surface residues attached to the surface thereof. Be transported.

  When the support base 113 approaches the vicinity of the bottom surface, the transport mechanism 110 moves the inflator pipe P in the transport direction X by returning the angle of the support base 113 to a substantially horizontal position. At this time, the inflator pipe P rolls with a change in the angle of the support base 113 and fits in the recess 116 a of the support portion 115.

  Then, when detecting that the inflator pipe P has moved to a position facing the inner surface cleaning unit 130 in the width direction Y from the sensor or the conveyance cycle, the cylindrical body cleaning device 1, as shown in FIG. The supply unit 60 is operated and the regenerated cleaning liquid is ejected from the inner surface cleaning unit 130 toward the inside of the inflator pipe P through the supply pipe 3. At this time, in the inflator pipe P, the surface residue adhered to the inner surface is removed by the ejection pressure of the regenerated cleaning liquid, and the cleaning liquid CF staying in the inflator pipe P is discharged in the direction of ejecting the regenerated cleaning liquid.

When it is detected from the sensor or the conveyance cycle that the support base 113 has moved through the inner surface cleaning unit 130 and directly below the outer surface cleaning unit 140, the cylindrical body cleaning device 1 is shown in FIG. 6 (a). Compressed air is supplied to the actuator 142 of the outer surface cleaning unit 140 in the initial state, the brush unit 143 is moved outward in the width direction Y, and the surface residue attached to the outer surface of the inflator pipe P is removed with the brush 148. .
When the inflator pipe P passes through the outer surface cleaning unit 140, the cylindrical body cleaning device 1 operates the actuator 142 of the outer surface cleaning unit 140 to return the brush unit 143 to the initial state.

  Thereafter, the transport mechanism unit 110 moves the support 113 from the cleaning tank 120 to the first blow unit 160 while tilting the edge on the transport direction X side upward. At this time, the inflator pipe P rolls as the angle of the support base 113 changes, as shown in part B in FIG. 2, escapes from the recess 116a of the support part 115, and the base part 116 and the upright part on the lower side. 117.

Then, when being carried out from the cleaning liquid CF, the support table 113 is carried out from the cleaning liquid CF while passing through the liquid surface portion undulated by the regenerated cleaning liquid ejected from the ejection section 150, as shown in part B in FIG. The
When the support 113 reaches the first blow unit 160, the cylindrical body cleaning device 1 operates the air compressor to pump the compressed air to the blow pipe 162, and the cleaning liquid CF attached to the outer surface and the inner surface of the inflator pipe P. Blow away and remove.

  Thereafter, when the support base 113 moves almost directly below the second crane 6 waiting on the first cleaning unit 10 side, the cylindrical body cleaning device 1 lowers and grips the second crane 6 as shown in FIG. The inflator pipe P thus obtained is conveyed to the second cleaning unit 20. At this time, the third crane 7 moves from the second cleaning unit 20 to the second blow unit 30 in conjunction with the movement of the second crane 6 in the transport direction X.

  When the second crane 6 moves substantially directly above the second cleaning unit 20, the cylindrical body cleaning device 1 lowers the second crane 6 and places the inflator pipe P on the support base 22 of the rinsing tank 21. At this time, since the rinsing liquid RF in the rinsing tank 21 is ultrasonically vibrated by the vibration element 23, the cleaning liquid CF and the surface residue remaining on the outer surface and the inner surface of the inflator pipe P are removed.

  During this time, the second crane 6 that has transported the inflator pipe P to the second cleaning unit 20 moves to the first cleaning unit 10 to transport the subsequent cylindrical body. At this time, the third crane 7 moves from the second blow unit 30 to the rinsing tank 21 in conjunction with the movement of the second crane 6.

  When the third crane 7 reaches substantially directly above the second cleaning unit 20, the cylindrical body cleaning apparatus 1 lowers the third crane 7 to carry out the inflator pipe P from the rinsing tank 21 and grip the inflator pipe P. The moved third crane 7 is moved to the second blow unit 30.

  When the third crane moves substantially right above the second blow unit 30, the cylindrical body cleaning device 1 lowers the third crane 7 and places the inflator pipe P on the support base 31 as shown in FIG. Place. Thereafter, as shown in FIG. 9B, the cylindrical body cleaning apparatus 1 operates the air compressor 39 to pressure-feed the pressurized air to the inner surface blow pipe 34 and the outer surface blow hose 35, and operates the actuator 33. Then, the inner blow pipe 34 is inserted into the inflator pipe P.

  When the tip of the inner surface blow pipe 34 penetrates the inflator pipe P, the cylindrical body cleaning apparatus 1 operates the actuator 33 in the direction of pulling out the inner surface blow pipe 34 from the inflator pipe P to bring the inner surface blow pipe 34 into the initial position. Return and stop the air compressor 39.

  After that, the cylindrical body cleaning apparatus 1 moves the fourth crane 8 almost directly above the second blow unit 30, and unloads the inflator pipe P from the second blow unit 30 with the fourth crane 8 to the drying unit 40. Transport.

  When the fourth crane 8 moves to the drying unit 40, the cylindrical body washing apparatus 1 lowers the fourth crane 8 and places the inflator pipe P on the support base 43 as shown in FIG. The drying unit 40 transports the inflator pipe P in the transport direction X, and completely dries the surface of the inflator pipe P with warm air introduced through the warm air inlet 44a in the drying box 44.

  Thereafter, the cylindrical body cleaning apparatus 1 transfers the inflator pipe P whose surface is completely dried to the next step, and finishes the cleaning of the inflator pipe P. In addition, when there exists a subsequent cylindrical body, the cylindrical body cleaning apparatus 1 repeats the operation | movement mentioned above.

  The cylindrical body cleaning apparatus 1 that realizes the above-described operation and the cylindrical body cleaning method using the cylindrical body cleaning apparatus 1 can transport the inflator pipe P continuously and clean the inflator pipe P efficiently.

  Specifically, when the longitudinal direction of the inflator pipe P and the conveyance direction X are substantially coincided with each other, the size of the cylindrical body cleaning device 1 in the substantially vertical direction or the substantially horizontal direction tends to increase, and the washing tank. The number of inflator pipes P that can be immersed in 120 tends to decrease.

  On the other hand, the cylindrical body cleaning apparatus 1 and the cylindrical body cleaning method perform cleaning by transporting the radial direction of the inflator pipe P whose longitudinal direction is substantially horizontal and the transport direction X to be substantially orthogonal to each other. More inflator pipes P can be transported and immersed in the tank 120, and the size of the device in the substantially vertical direction can be reduced.

  Further, the cleaning tank 120, the first blow unit 160, the second cleaning unit 20, the second blow unit 30, and the drying unit 40 are sequentially arranged by the roller chain 112, the second crane 6, the third crane 7, and the fourth crane 8. In order to convey the inflator pipe P, the cylindrical body cleaning device 1 and the cylindrical body cleaning method can continuously perform the cleaning of the inflator pipe P and the removal of the cleaning liquid CF attached to the inflator pipe P. At the same time, the removal of the cleaning liquid CF and the like adhering to the preceding inflator pipe P and the subsequent cleaning of the inflator pipe P can be performed simultaneously. Thereby, the cylindrical body washing | cleaning apparatus 1 and the cylindrical body washing | cleaning method can wash | clean the inflator pipe P efficiently while conveying the inflator pipe P continuously without interruption.

  In addition, for example, the first crane 5 for placing the inflator pipe P on the support base 113 and the second crane 6 for carrying out the inflator pipe P from the support base 113 can be configured separately by the transport mechanism unit 110. it can. For this reason, the cylindrical body cleaning apparatus 1 and the cylindrical body cleaning method are compared with the case where the inflator pipe P is carried in and out by the same crane, and the inflator pipe P in which the oil adhering to the crane or the like is cleaned. Can be prevented.

Thereby, the cylindrical body washing | cleaning apparatus 1 and the cylindrical body washing | cleaning method not only perform the washing | cleaning of the inflator pipe P and removal of the washing | cleaning liquid CF, but can wash | clean the inflator pipe P reliably.
Therefore, the cylindrical body cleaning apparatus 1 and the cylindrical body cleaning method can transport the inflator pipe P continuously without interruption and can clean the inflator pipe P more efficiently and reliably.

Moreover, the cylindrical body washing | cleaning apparatus 1 can wash | clean the outer surface of the inflator pipe P uniformly by comprising the support stand 113 with the base part 116 and the standing part 117. FIG.
Specifically, for example, in the case of a support base that holds both ends of the inflator pipe P, a portion of the inflator pipe P that contacts the support base may be insufficiently cleaned.

  On the other hand, by forming the support base 113 with the base part 116 and the upright part 117, the tubular body cleaning apparatus 1 allows the inflator pipe P to roll between the upright parts 117 in the cleaning liquid CF. The surface of the pipe P can be cleaned evenly.

Thereby, the cylindrical body washing | cleaning apparatus 1 not only can wash | clean the inflator pipe P and the removal of the washing | cleaning liquid CF efficiently, but can wash | clean the surface of the inflator pipe P more reliably.
Accordingly, the cylindrical body cleaning apparatus 1 can continuously convey the inflator pipe P without interruption, and can clean the inflator pipe P more efficiently and more reliably.

Further, the provision of the regenerating liquid supply unit 60 and the ejection unit 150 makes it possible to prevent the floating oil Fo that has floated on the surface of the cleaning liquid CF from adhering to the inflator pipe P carried out from the cleaning liquid CF.
Specifically, the regenerated cleaning liquid ejected from the ejection unit 150 can make the liquid surface of the cleaning liquid CF near the position where the inflator pipe P is carried out, such as oil floating on the liquid surface of the cleaning liquid CF. The floating oil Fo can be pushed to the outlet path 121.

  That is, the cylindrical body cleaning apparatus 1 can prevent the floating oil Fo floating on the liquid surface of the cleaning liquid CF from drifting near the position where the inflator pipe P is carried out. For this reason, when the inflator pipe P is carried out from the cleaning liquid CF, the cylindrical body cleaning apparatus 1 can prevent the floating oil Fo from adhering to the inflator pipe P.

Furthermore, by ejecting the regenerated cleaning liquid, the cylindrical body cleaning apparatus 1 can make the state of the cleaning liquid CF near the position where the inflator pipe P is carried out better. Thereby, the cylindrical body washing | cleaning apparatus 1 can prevent the washing | cleaning defect of the inflator pipe P. FIG.
Accordingly, the cylindrical body cleaning apparatus 1 can prevent the floating oil Fo from adhering to the inflator pipe P by the regenerated liquid supply unit 60 and the ejection unit 150, and can clean the inflator pipe P efficiently.

In addition, the cylindrical body cleaning device 1 can reliably clean the inner surface of the inflator pipe P by including the regenerated liquid supply unit 60 and the inner surface cleaning unit 130.
Specifically, since the conveyance direction X of the inflator pipe P and the radial direction of the inflator pipe P substantially coincide with each other, it is difficult to expect the cleaning liquid CF to flow due to the conveyance inside the inflator pipe P.

  For this reason, when the inflator pipe P is carried out from the cleaning liquid CF, there is a possibility that oil or dust in the cleaning liquid CF may adhere to the inner surface of the inflator pipe P. Furthermore, since the vibration by the vibration element 122 is difficult to be transmitted to the cleaning liquid CF inside the inflator pipe P, there is a possibility that the surface residues such as oil and dust attached to the inner surface of the inflator pipe P may not be completely removed.

  Therefore, the regenerative liquid supply unit 60 and the inner surface cleaning unit 130 allow the cylindrical body cleaning device 1 to clean the inner surface of the inflator pipe P by the regenerative cleaning liquid jet pressure, and to positively wash the cleaning liquid CF inside the inflator pipe P. It can be made to flow. For this reason, the cylindrical body cleaning apparatus 1 prevents the removed surface residue from staying inside the inflator pipe P, and when the inflator pipe P is carried out from the cleaning liquid CF, the removed surface residue is removed from the inflator. It can prevent adhering to the inner surface of the pipe P.

Furthermore, by providing the inner surface cleaning unit 130 in the cleaning tank 120, the cylindrical body cleaning apparatus 1 can perform continuous conveyance of the inflator pipe P and cleaning of the inner surface of the inflator pipe P at the same time.
Therefore, the cylindrical body cleaning apparatus 1 can more reliably clean the inner surface of the inflator pipe P by the regenerated liquid supply unit 60 and the inner surface cleaning unit 130, and can transport the inflator pipe P more efficiently.

  In addition, by providing the cleaning tank 120 with the brush part 143 and the actuator 142, the surface residue attached to the outer surface of the inflator pipe P that could not be removed by ultrasonic cleaning is removed by the brush part 143 movable in the width direction Y. It can be removed reliably. For this reason, the cylindrical body washing | cleaning apparatus 1 can wash | clean the outer surface of the inflator pipe P reliably.

Furthermore, by providing the brush part 143 in the cleaning tank 120, the cylindrical body cleaning apparatus 1 can perform continuous conveyance of the inflator pipe P and cleaning of the outer surface of the inflator pipe P at the same time.
Therefore, the cylindrical body cleaning apparatus 1 can more reliably clean the outer surface of the inflator pipe P by the brush portion 143 and the actuator 142, and can transport the inflator pipe P more efficiently.

  Further, by providing the base 116 in the support base 113 with the recess 116a, the inflator pipe P is prevented from falling from the support base 113, and the inflator pipe P can be easily carried into and out of the support base 113. Can do.

  Specifically, for example, in the case of a support base that does not have the recess 116a in the base portion 116, when the support base immersed in the cleaning liquid CF together with the inflator pipe P is carried out of the cleaning tank 120 while changing its inclination, the inflator pipe P rolls on the support base. At this time, because the pair of support portions support the vicinity of both ends of the inflator pipe P, when the inflator pipe P rolls so that the longitudinal direction substantially coincides with the diagonal line of the pair of support portions, One end may fall from one support part.

  Therefore, by providing the concave portion 116a in the base portion 116, the tubular body cleaning device 1 allows the rolled inflator pipe P to fit into the concave portion 116a, so that the inflator pipe P falls down as the angle of the support 113 is changed. And the position of the inflator pipe P placed on the support base 113 can be easily specified.

For this reason, for example, when the support base 113 is carried out from the cleaning tank 120, the cylindrical body cleaning device 1 can easily carry out the inflator pipe P from the support base 113 by the second crane 6.
Therefore, the cylindrical body cleaning apparatus 1 can prevent the inflator pipe P from falling from the support base 113 and more efficiently carry the inflator pipe P by providing the recess 116a.

  Further, since the second blow unit 30 is configured by the inner surface blow pipe 34, the outer surface blow hose 35, and the air compressor 39, the cleaning liquid CF adhering to the inner surface and the outer surface of the inflator pipe P carried out from the cleaning tank 120 is removed. It can be removed at the same time. For this reason, the cylindrical body cleaning apparatus 1 can efficiently remove the cleaning liquid CF even if it is a substantially cylindrical inflator pipe P having inner and outer surfaces.

Further, since the recovery storage tank 51 and the regenerative liquid supply unit 60 are provided, the cylindrical body cleaning apparatus 1 can reuse the cleaning liquid CF overflowing from the cleaning tank 120 with a simple configuration without waste.
Specifically, the cylindrical body cleaning device 1 supplies the cleaning liquid CF overflowing from the cleaning tank 120 by supplying the cleaning liquid CF from which oil and dust have been separated to the cleaning tank 120 as a regenerated cleaning liquid in the recovery storage tank 51. It is possible to prevent oil and dust from staying in the cleaning liquid CF in the cleaning tank 120 by reusing without waste and actively replacing the cleaning liquid CF in the cleaning tank 120.

  Furthermore, by connecting the regenerated liquid supply unit 60 to the ejection unit 150 and the inner surface cleaning unit 130, the cylindrical body cleaning apparatus 1 can simultaneously perform the circulation of the cleaning liquid CF, the cleaning of the inner surface of the inflator pipe P, and the like. . For this reason, the cylindrical body cleaning apparatus 1 can circulate the cleaning liquid CF more efficiently and efficiently.

In addition, for example, compared with the case where the cleaning liquid CF overflowing from the cleaning tank 120 is vaporized and evaporated to obtain the regenerated cleaning liquid, the cylindrical body cleaning apparatus 1 can obtain the regenerated cleaning liquid with a simple configuration. The size can be reduced and the cost can be reduced.
Therefore, the cylindrical body cleaning apparatus 1 can reuse the cleaning liquid CF overflowing from the cleaning tank 120 with a simple configuration without waste by using the collection and storage tank 51 and the regenerative liquid supply unit 60, and more efficiently using the inflator pipe P. Can be washed.

  Further, since the oil skimmer 52 is provided in the collection storage tank 51, for example, the cylindrical body cleaning apparatus 1 is more capable of separating the oil by vaporizing and evaporating the cleaning liquid CF overflowing from the cleaning tank 120. The oil content in the collection storage tank 51 can be removed with a simple configuration.

  In addition, in the above-mentioned embodiment, although the cylindrical body washing | cleaning apparatus 1 was comprised by the 1st washing | cleaning part 10, the 2nd washing | cleaning part 20, the 2nd blow part 30, and the drying part 40, it is not limited to this, An inflator pipe Any structure that can clean and dry P may be used. For example, it is good also as the cylindrical body washing | cleaning apparatus 1 comprised by the 1st washing | cleaning part 10 and the drying part 40. FIG. Or it is good also as the cylindrical body washing | cleaning apparatus 1 comprised by the 1st washing | cleaning part 10 which replaced the 1st blow part 160 with the 2nd blow part 30, and the drying part which air-drys the inflator pipe P naturally.

  Moreover, although the support stand 113 was fixed to the roller chain 112, it is not limited to this, The support stand 113 is fixed to a substantially annular belt, the support stands 113 are directly connected and fixed, or the first cleaning unit 10. It is good also as a structure which fixes the support stand 113 to the crane which can be raised / lowered while circulating by the elliptical track | orbit in planar view.

  The roller chain 112 is driven to circulate around the cleaning tank 120. However, the present invention is not limited to this, and the roller chain 112 includes the cleaning tank 120, the first blow unit 160, the second cleaning unit 20, and the second blow unit. It is good also as a structure which carries out circulation drive in order of 30 and the drying part 40, and conveys the inflator pipe P. FIG.

Further, although the vibration elements 122 and 23 are disposed outside the bottom surfaces of the cleaning tank 120 and the rinsing tank 21, the present invention is not limited thereto, and the vibration elements are placed inside the bottom surfaces of the cleaning tank 120 and the rinsing tank 21. Also good.
In addition, although the substantially bowl-shaped ejection portion 150 having the plurality of ejection openings 151 is provided, the present invention is not limited to this, and the cleaning liquid CF flows from the vicinity of the position where the inflator pipe P is unloaded from the cleaning liquid CF toward the outlet path 121. As long as it can be configured, it may be configured in an appropriate shape.

  Moreover, although the regeneration washing | cleaning liquid was ejected from the ejection part 150, it will not be limited to this, For example, if the liquid surface can be waved, the ejection part 150 and the regeneration liquid supply part 60 will not be connected but the ejection part 150, for example. And an air compressor may be connected and pressurized air may be ejected from the ejection part 150.

  Moreover, although the inner surface washing | cleaning part 130 was made into the substantially cylindrical shape, if it is a shape which can wash | clean the inner surface of the inflator pipe P, it is good also as an appropriate shape. For example, the inflator pipe P side may have a shape in which the diameter is increased so that the regenerated cleaning liquid is ejected while being diffused.

  In addition, when the support 113 is moved to a position where the inner surface cleaning unit 130 and the inflator pipe P are opposed to each other in the width direction Y, the regenerated cleaning liquid is ejected from the inner surface cleaning unit 130. It is good also as a structure which ejects a regeneration washing | cleaning liquid. At this time, a guide or the like for restricting the movement of the inflator pipe P in the width direction Y may be provided so that the inflator pipe P does not fall off the support base 113 due to the regenerated cleaning liquid ejected from the inner surface cleaning unit 130.

  Further, the outer surface cleaning unit 140 is configured by the brush unit 143 movable in the width direction Y. However, the configuration is not limited thereto, and any appropriate configuration may be used as long as the outer surface of the inflator pipe P transported in the transport direction X can be cleaned. It is good. For example, it is composed of a substantially cylindrical brush base and a brush fixed toward the radially outer side of the brush base, and the substantially cylindrical brush base is connected to a drive motor and rotated about the longitudinal direction of the brush base as the center of rotation. It is good also as a rotating brush part to do.

  In addition, the regenerative liquid supply unit 60 is connected to the inner surface cleaning unit 130 and the ejection unit 150. However, the present invention is not limited to this, and the regenerative liquid supply unit 60 and the cleaning tank 120 are connected. It is good also as a structure which supplies.
