Description

  The present invention relates to a manufacturing apparatus and a manufacturing method of a decorative object, and in particular, by pressing a decorative object against a decorative layer provided on the surface of a water-soluble film floated on the water surface, It is related with the improvement of the manufacturing apparatus of the decorating object which transcribe | transferred a decorating layer to the surface of to-be-decorated object, and manufacturing a decorating object, and the advantageous manufacturing method of such a decorating object.

  As is well known, there are devices having various structures for producing decorative objects by forming a decorative layer having a predetermined pattern or pattern on the surface of the object to be decorated. In the production of the decoration item, for example, the shape and size of the object to be decorated, or the one having a structure suitable for the conditions for forming the decoration layer on the surface of the object to be decorated is appropriately selected, It is used. And as a kind of the manufacturing apparatus of such a decoration, the manufacturing apparatus of the decoration as clarified by Unexamined-Japanese-Patent No. 4-43100 (patent document 1) etc. is known, for example.

  This decoration manufacturing apparatus has a water tank and a water supply device for supplying water into the water tank. A so-called transfer film in which a water-insoluble decorative layer composed of a printing layer using ink or paint or the like is formed on the surface of a water-soluble (including water-swellable) film is formed by a water supply device. When the water-soluble film of the transfer film is floated on the water surface in the supplied water tank and the object to be decorated is pressed against the decorative layer on the water surface and submerged, A decoration layer is transcribe | transferred to the surface of a to-be-decorated object, and the target decoration is manufactured.

  By using such a decoration manufacturing apparatus, a decoration layer can be easily formed on a surface to be decorated having a relatively complicated shape such as a three-dimensional shape. Therefore, such a manufacturing apparatus is suitably used as an apparatus for manufacturing automobile interior parts or the like in which various patterns are formed on a surface formed by combining a plurality of types of curved surfaces, for example.

  By the way, if a device for producing a decorative object having the structure as described above is used, a process of floating a transfer film on the water surface in the water tank, and a process of pressing the object to be decorated against the decorative layer of the transfer film and submerging it. By repeatedly carrying out such a cycle as one cycle, a plurality of decorations can be continuously produced. However, when continuously producing a plurality of decorative objects in this way, a part of the decorative layer and the residue of the water-soluble film (hereinafter referred to as the transfer film residue) that were not used in the previous transfer process. However, it adheres to the transfer film floated on the water surface in the water tank for the next transfer process, which may cause a deterioration in the quality of the decoration to be manufactured.

  That is, the transfer film has a feature that when the water-soluble film is dissolved (swelled and decomposed) in water, the entire decorative layer expands, but foreign matter adheres to the transfer film. And the way of melting differs between the part of the water-soluble film where foreign matter is attached and the other part. Therefore, if the residue of the transfer film adheres to a new transfer film that floats on the water surface in the water tank for the next transfer process, the amount of expansion of the decorative layer when the water-soluble film dissolves in water Partial differences may occur, and the pattern of the decorative layer may be partially changed, resulting in a problem that the appearance of the decorative object having such a decorative layer transferred to the surface is degraded. There is.

  Therefore, the conventional decoration manufacturing apparatus having the above-described structure prevents foreign matter from adhering to the transfer film floated on the water surface in the water tank when a plurality of decorations are continuously manufactured. Ingenuity for it is given. That is, in such a manufacturing apparatus, the water tank is divided into two by the partition wall, and the transfer tank and the septic tank are formed in the water tank. Further, water is continuously supplied into the transfer tank by the water supply device, and water that overflows (overflows) from the transfer tank due to the continuous water supply flows out into the septic tank beyond the partition wall. It is like that. Thus, in such an overflow type decorative product manufacturing apparatus, the transfer of the decorative layer to the surface of the object to be decorated is performed in the transfer tank, while the transfer film remains in the water in the transfer tank and floats. This residue is configured to flow out of the transfer tank together with the water overflowed from the transfer tank into the purification tank and be removed from the stored water stored in the transfer tank. Then, when continuously producing a plurality of decorations, the transfer film residue is as much as possible with respect to the transfer film floated on the water surface in the transfer tank for the next transfer process. It is devised not to adhere.

  However, in such a conventional overflow type manufacturing apparatus, only the transfer film residue contained in the stored water in the transfer tank is included in the surface layer portion of the stored water overflowing from the transfer tank. It was supposed to be removed. For this reason, the residue of the transfer film contained in the portion other than the surface layer of the stored water remaining in the transfer tank without overflowing from the transfer tank cannot be removed, and is therefore floated on the water surface in the transfer tank. It has never been possible to eliminate any residue adhering to the transfer film. Therefore, in a conventional overflow type decoration manufacturing apparatus, it has been difficult to continuously manufacture a plurality of decorations with high quality that can be sufficiently satisfied.

  In addition, in order to completely remove the residue of the transfer film from the stored water in the water tank (transfer tank) when continuously producing a plurality of decorative objects, the process of transferring the decorative layer to the surface of the object to be decorated It is conceivable that after the entire amount of stored water is discharged from the water tank every time, the water is supplied again into the water tank. And the manufacturing apparatus of the so-called stored water exchange type decorating object which changed the whole quantity of the stored water in a water tank every time the manufacturing process of one decorating object is complete | finished is also small, for example. It is actually used when manufacturing decorative items.

  However, the following problems have been inherent in such a conventional stored water exchange type decoration manufacturing apparatus.

  That is, in the conventional stored water exchange type decorative article manufacturing apparatus, generally, water is supplied into the aquarium by water discharge from a water supply pipe installed above or around the aquarium. When the water supply is completed, the water surface fluctuates. The fluctuation of the water surface when the water supply is completed becomes larger as the water supply speed into the water tank (the amount of water absorbed per unit time) increases. And such a large fluctuation of the water surface causes wrinkles and deformation in the decorative layer of the transfer film floated on the water surface.

  Therefore, when using a conventional stored water exchange type decoration manufacturing apparatus, the water supply speed is reduced and the water is gently supplied into the aquarium, thereby reducing the fluctuation of the water surface when the water supply is completed. Alternatively, if the water supply speed into the water tank is not reduced, it is necessary to wait for the fluctuation of the water surface to sufficiently settle after completion of the water supply, and then to float the transfer film on the water surface. Therefore, when producing a decoration using such a device for manufacturing a decoration, from the time of water supply to the water tank or the completion of water supply to the water tank until the transfer film is floated on the water surface and set. It was inevitable that the time was increased, and as a result, the production cycle time of the decorative product was increased.

  Hereinafter, in order to clarify the present invention more specifically, embodiments of the present invention will be described in detail with reference to the drawings.

  First, in FIG. 1, an interior part for an automobile as an example of a decorative product manufactured using a manufacturing apparatus for a decorative product having a structure according to the present invention is shown in its cross-sectional form. As is clear from FIG. 1, the automobile interior part 10 (hereinafter simply referred to as the interior part 10) has a substrate 12 as a decoration object, which is made of a resin flat plate. And the decoration layer 14 which consists of a printing layer etc. which presents the grain pattern etc. which were formed using the ink, the paint, etc. on one surface of the thickness direction of this board | substrate 12 is laminated | stacked and comprised. . The material and shape of the substrate 12 are not limited to this. Further, the decorative layer 14 may be other than the printed layer, and even if it is a pattern other than a wood grain pattern or a predetermined pattern, there is no problem.

  A plurality of such interior parts 10, for example, an interior part manufacturing apparatus 16 (hereinafter simply referred to as a manufacturing apparatus 16) as an embodiment of a manufacturing apparatus having a structure according to the present invention as shown in FIG. 2. ) Is continuously produced.

  As apparent from FIG. 2, the manufacturing apparatus 16 of the present embodiment includes a water tank 18, a water supply apparatus 20 as a water supply means, and a drain pipe 22. In the following, for the sake of convenience, the upper side of FIG. 1 is referred to as the upper side of the manufacturing apparatus 16, and the lower side of FIG. 1 is referred to as the lower side of the manufacturing apparatus 16.

  More specifically, as shown in FIGS. 2 to 4, the water tank 18 includes a cylindrical peripheral wall portion 24 extending in the vertical direction and a bottom wall portion 26 that closes the lower opening of the cylindrical peripheral wall portion 24. As a whole, it has a cylindrical shape with a bottom on one side that opens upward. The cylindrical peripheral wall portion 24 of the water tank 18 has a cylindrical shape with a relatively low height, and the bottom wall portion 26 has a tapered shape in which the inner peripheral surface gradually decreases in diameter downward. ing.

  At the center of the bottom wall portion 26 of the water tank 18, a communication port 28, which is a circular through hole, is provided so as to be positioned coaxially with the central axis P of the water tank 18. . That is, here, the bottom wall portion 26 as a whole has a tapered cylindrical shape that gradually decreases in diameter toward the lower side, and the small-diameter side opening portion serves as a communication port 28. A communication port 28 is formed in the deepest part of the water tank 18. Further, such a communication port 28 is arranged so that the vertical line: X extending vertically through the center point: O coincides with the central axis: P of the water tank 18 (cylindrical peripheral wall portion 24). It is.

  And in the center part of the outer surface (lower surface) of the bottom wall part 26, the cylindrical connection cylinder part 30 extends straightly downward from the opening peripheral part of the communicating port 28, and the central axis of the water tank 18: P So as to be positioned coaxially with each other. Thereby, the inner space surrounded by the cylindrical peripheral wall portion 24 and the bottom wall portion 26 of the water tank 18 communicates with the inner space (inner hole) of the connection cylinder portion 30 through the communication port 28, and further, these communication ports. 28 and the inside space of the connecting cylinder part 30 communicate with the outside. Here, a step portion 32 is provided at an intermediate portion in the axial direction of the connection tube portion 30, and an end portion below the step portion 32 of the connection tube portion 30 is compared to a portion above the step portion 32. Thus, the diameter is reduced by a predetermined dimension. And such a water tank 18 is supported by the support frame 36 which consists of a rectangular frame standing on the base 34 which the manufacturing apparatus 16 has.

  As apparent from FIGS. 2 and 3, the drain pipe 22 is a cylindrical straight pipe having substantially the same inner diameter as that of the connecting cylinder portion 30 and extending in the vertical direction. And so that this drain pipe 22 may be located coaxially with the water tank 18, in other words, with the central axis Q aligned with the central axis P of the water tank 18, the connecting cylinder is connected to the water tank 18. It is detachably attached via the part 30.

  That is, the upper end portion of the drain pipe 22 is provided with a step portion 38, and the upper portion of the step portion 38 is increased in diameter by a predetermined dimension as compared with the lower portion thereof. Yes. And the upper end part of the large diameter of this drain pipe 22 is extrapolated to the lower end part of the small diameter of the connection cylinder part 30, and the lower end surface of the connection cylinder part 30 is engaging with the step part 38 of the drain pipe 22. On the other hand, the upper end surface of the drain pipe 22 is engaged with the stepped portion 32 of the connection cylinder part 30, so that the upper end part of the drain pipe 22 and the lower end part of the connection cylinder part 30 are inlay-fitted. In such a state, the upper end portion of the drain pipe 22 and the lower end portion of the connecting tube portion 30 that are fitted to each other are connected to each other by the connecting band 40. The connecting band 40 is configured such that two half-cylindrical parts are hinge-connected at one circumferential end, and are connected to each other by bolting at the other circumferential end. Yes. A seal rubber 41 is attached to the inner peripheral surface of the connecting band 40.

  Thus, here, the connecting band 40 is extrapolated to the fitting portion between the upper end portion of the drain pipe 22 and the lower end portion of the connecting cylinder portion 30, and the other portion in the circumferential direction is tightened. Since the bolts are fixed at the end portions, the drain pipe 22 and the connecting cylinder portion 30 are connected to each other while being liquid-tightly sealed. Accordingly, the drain pipe 22 communicates with the inside space of the connection cylinder part 30 under the connection with the connection cylinder part 30, and the cylinder of the water tank 18 passes through the connection cylinder part 30 and the communication port 28. The inner space surrounded by the peripheral wall portion 24 and the bottom wall portion 26 is also communicated. And the connection of the drain pipe 22 and the connection cylinder part 30 is canceled by loosening the volt | bolt of the connection band 40 from the connection state of such a drain pipe 22 and the connection cylinder part 30. FIG. Thus, the drain pipe 22 (the water tank 18) is detachably attached to the water tank 18 (with respect to the drain pipe 22) via the connecting cylinder portion 30.

  As shown in FIG. 2, the drain pipe 22 is connected to a water storage tank 42 disposed on the base 34 at the lower end thereof. The water storage tank 42 has a volume that exceeds the volume of the water tank 18. Further, an opening / closing valve 44 as an opening / closing means is provided at an intermediate portion in the axial direction of the drain pipe 22. Here, the opening / closing valve 44 is composed of an electromagnetic valve having a known structure, and the opening / closing operation allows or stops the flow of water in the drain pipe 22.

  Thus, in the manufacturing apparatus 16, the water that is supplied into the water tank 18 by the water supply apparatus 20 that will be described in detail later and stored is passed through the communication port 28 and the connecting cylinder part 30 when the opening / closing valve 44 is opened. The water is discharged from the water tank 18, flows into the drain pipe 22, and is guided into the water storage tank 42 through the drain pipe 22 to be stored in the water storage tank 42. As is clear from this, in the present embodiment, the drainage flow path 45 is configured by the connection cylinder portion 30 and the drainage pipe 22. Further, such a drainage channel 45, the communication port 28, and the open / close valve 44 constitute a drainage means.

  On the other hand, a heater device 43 having a known structure is provided in parallel in a water storage tank 42 to which the drain pipe 22 is connected. As will be described later, when the transfer film 54 described later floats on the surface of the stored water that has been supplied again from the water storage tank 42 into the water tank 18 and stored, the heater device 43 transfers the transfer film 54. The water-soluble film 90 heats the water in the water storage tank 42 to such a temperature that it can be quickly dissolved in the water in the water tank 18 (see FIG. 8).

  Further, an upper filtration filter device 46 as a filtering means and a lower filtration filter are provided at a portion of the drainage pipe 22 (drainage channel 45) located between the connection portion to the water storage tank 42 and the installation portion of the opening / closing valve 44. The apparatus 48 is installed so that it may be located in a line at predetermined intervals in the up-down direction. The upper and lower filtration filter devices 46 and 48 are configured by storing known filtration filters (not shown) in filter holders 50 and 52 fixed to the drain pipe 22, respectively.

  As described above, the upper filtration filter device 46 and the lower filtration filter device 48 are provided in the middle of the drain pipe 22, so that the water discharged from the water tank 18 flows while flowing through the drain pipe 22. And it filters by the lower filtration filter apparatus 46,48. Thus, the residue 92 (see FIG. 9) of the transfer film 54, which will be described later, mixed in the water flowing in the drain pipe 22 is collected by the filtration filters in the upper and lower filtration filter devices 46, 48. It is like that. Thus, the water in the drain pipe 22 is purified and then sent into the water storage tank 42 to be stored.

  Note that the structure and type of the filtration filters in the upper and lower filtration filter devices 46 and 48 are not limited in any way, and various known filters are employed. Here, each of these filters is a HEPA filter. It is composed of. And the diameter of the pore which the filtration filter in the lower filtration filter apparatus 48 has is made smaller than the diameter of the pore which the filtration filter in the upper filtration filter apparatus 46 has, and it mixes in the water which flows in the drain pipe 22 The residue 92 of the transfer film 54 to be collected is more reliably collected in two stages. Moreover, you may provide a filtration filter apparatus in the upper part rather than the installation part of the on-off valve 44 of the drain pipe 22 separately from the upper side and lower side filtration filter apparatuses 46 and 48 as needed. By doing so, it is possible to prevent the residue 92 of the transfer film 54 from entering the open / close valve 44. Further, the number of filtration filter devices provided in the drain pipe 22 is not limited in any way, and the number of filtration filter devices installed on the drain pipe 22 may be only one, and the upper and lower filtration filter devices. 46 and 48 may be omitted.

  As shown in FIGS. 2 to 4, the water supply apparatus 20 includes a water supply pump 56 that is installed on the base 34 and has a known structure. The water supply pump 56 is connected to the water storage tank 42 via a water supply pipe 58. Moreover, the 1st water supply pipe 60, the 2nd water supply pipe 62, and the 3rd water supply pipe 64 are connected to the water supply pump 56, respectively. The first, second, and third water supply pipes 60, 62, 64 have first, second, and third water supply openings at the ends opposite to the connection side with the water supply pump 58, respectively. Ports 66, 68, and 70 are provided.

  Thus, in the manufacturing apparatus 16 of the present embodiment, the water stored in the water storage tank 42 is sucked into the water supply pump 56 through the water supply pipe 58 by the operation of the water supply pump 56, and further, the first to third water supply pipes. It circulates in the 60, 62, 64, and it is made to eject from the 1st thru | or 3rd water supply port 66,68,70. In FIG. 2, reference numeral 72 denotes an open / close valve made of, for example, an electromagnetic valve that opens and closes the flow of water in the water supply pipe 58. It is also possible to provide a filtration filter device having the same structure as the upper filtration filter device 46 and the lower filtration filter device 48 in the middle of the water supply pipe 58.

  Of the first to third water supply pipes 60, 62, 64 connected to the water supply pump 56, the first water supply pipe 60 is made of a material that can be easily bent and deformed over its entire length. And the edge part on the opposite side to the connection side to the water supply pump 56 is detachable into the first insertion hole 74 provided at one place on the circumference in the upper part of the cylindrical peripheral wall part 24 of the water tank 18. It is inserted.

  That is, in the first water supply pipe 60, the end on the first water supply port 66 side is inserted into the first insertion hole 74, and the first water supply port 66 side than the insertion portion into the first insertion hole 74. This portion is inserted into the inner space of the cylindrical peripheral wall portion 24, and the first water supply port 66 opens toward the inner space of the cylindrical peripheral wall portion 24. Thereby, the water fed from the water supply pump 56 and flowing through the first water supply pipe 60 is supplied into the water tank 18 through the first water supply port 66.

  Here, in the first water supply pipe 60, the portion extending from the first insertion hole 74 to the outside of the water tank 18 in the end side portion on the first water supply port 66 side extends from the upper end of the support frame 36 to the side. Removably inserted through a cylindrical pipe holder 76 provided at the tip of the extension frame 73 is held. Thereby, the state of insertion of the first water supply pipe 60 into the first insertion hole 74 is stably maintained. Moreover, the flow of the water in the 1st water supply pipe 60 is opened and closed in the part between the insertion site | part into the 1st insertion hole 74 of such a 1st water supply pipe 60, and the insertion site | part to the pipe holder 76. For example, an open / close valve 77 made of an electromagnetic valve or the like is provided.

And as FIG. 4 shows, in the manufacturing apparatus 16 of this embodiment, the edge part by the side of the 1st water supply port 66 of the 1st water supply pipe 60 which plunged into the inner side space of the cylindrical surrounding wall part 24 of the water tank 18 is shown. , The central axis of the first water supply pipe 60: R, the central point of the first water supply port 66: α and the central axis of the water tank 18: one point on the P: β, a straight line extending horizontally: S : Arranged so as to extend in the intersecting direction with θ ₁ .

That is, as shown in FIG. 10, the first water supply port 66 uses the center line R ′ of the flow of water supplied from the first water supply port 66 toward the water tank 18 as the center point of the communication port 28: Vertical line extending in the vertical direction through O (see FIG. 3): One point on X: β and the center point of first water supply port 66: A straight line extending horizontally connecting α: Cylindrical peripheral wall with respect to S It is provided at a position where it intersects in the circumferential direction of the portion 24. In other words, the opening direction of the first water supply port 66 into the inner space of the cylindrical peripheral wall portion 24 indicates the center line: R ′ of the flow of water supplied from the first water supply port 66 as the first water supply port 66. The center point of the water tank 18: A central axis of the water tank 18: A point on the P: β, which extends horizontally, intersects the straight line S with an angle of intersection: θ ₁ in the circumferential direction of the cylindrical peripheral wall 24. Has been.

Thus, the water flowing through the first water supply pipe 60 has a predetermined angle with respect to the direction toward the central axis P of the water tank 18: P (direction along the straight line S) under the open operation state of the opening / closing valve 77. The water is supplied from the first water supply port 66 into the water tank 18 in a direction shifted in the circumferential direction of the cylindrical peripheral wall portion 24 by θ ₁ . That is, the water flowing through the first water supply pipe 60 is opposite to the first water supply port 66 in the inner peripheral surface of the cylindrical peripheral wall portion 24 in the radial direction with the central axis P of the water tank 18 interposed therebetween. The location on the side is supplied from the first water supply port 66 into the water tank 18 toward the inner peripheral surface portion located at a different location in the circumferential direction of the cylindrical peripheral wall portion 24.

  On the other hand, as shown in FIGS. 3 and 5, the second water supply pipe 62 and the third water supply pipe 64 have the same inner diameter, and the end opposite to the connection side to the water supply pump 56 is The drain pipe 22 is inserted into and fixed to the upper side portion.

  More specifically, a second insertion hole 78 and a third insertion hole 80 are provided in a portion located between the installation portion of the opening / closing valve 44 and the connection portion with respect to the connection cylinder portion 30, which is an upper side portion of the drain pipe 22. The drainage pipe 22 is formed so as to penetrate through the pipe wall. The second insertion hole 78 and the third insertion hole 80 are coaxially positioned on both sides in the radial direction of the drain pipe 22 with the central axis Q of the drain pipe 22 interposed therebetween. And while the edge part by the side of the 2nd water supply port 68 of the 2nd water supply pipe 62 is penetrated in the 2nd insertion hole 78 so that removal is impossible, it is on the 3rd water supply port 70 side of the 3rd water supply pipe 64. The end portion is inserted into the third insertion hole 80 so as not to be removable. In addition, the second water supply pipe 62 and the third water supply pipe 64 are located in front of the second insertion hole 78 and the third insertion hole 80 (the second and third water supply ports 68 and 70 are referred to as the side). On the opposite side), open / close valves 69 and 71 made of, for example, electromagnetic valves are provided for opening and closing the flow of water in the second and third water supply pipes 62 and 64, respectively.

  Thus, the second water supply port 68 of the second water supply pipe 62 and the third water supply port 70 of the third water supply pipe 64 having the same diameter are arranged so as to open toward the inner space of the drainage pipe 22. ing. Accordingly, the water supplied from the water supply pump 56 and flowing through the second water supply pipe 62 and the third water supply pipe 64, respectively, under the open operation state of the open / close valves 69 and 71, 68 and the third water supply port 70 are supplied into the drain pipe 22.

  Then, the water supply into the drain pipe 22 through the second and third water supply ports 68 and 70 is performed under the closed operation state of the opening / closing valve 44 on the drain pipe 22, thereby After the inside of the upper part of the opening / closing valve 44 and the inner space of the connecting cylinder part 30, that is, the upper part of the drainage channel 45, are filled with water supplied into the drainage pipe 22, such drainage is performed. The water filled in the upper side portion of the flow path 45 is supplied and stored in the inner space surrounded by the cylindrical peripheral wall portion 24 and the bottom wall portion 26 of the water tank 18 through the communication port 28. (See FIG. 6). As is clear from this, here, the main chamber 82 is configured in the inner space surrounded by the cylindrical peripheral wall portion 24 and the bottom wall portion 26 of the water tank 18, while the drain pipe 22 is opened and closed. A sub chamber 84 is configured in the inner space above the valve 44 and in the inner space of the connecting cylinder portion 30 (the inner space of the upper portion of the drainage channel 45). And the surrounding wall part of such a subchamber 84 is comprised by the pipe wall part of the drain pipe 22. FIG.

  Thus, in the manufacturing apparatus 16 of the present embodiment, the water in the water storage tank 42 is supplied into the water tank 18 by the water supply pump 56 and the second and third water supply pipes 62 and 64, and the water tank 18. The water in the tank is discharged from the water tank 18 through the drainage channel 45 and stored in the water storage tank 42 so that a predetermined amount of water is circulated between the water tank 18 and the water storage tank 42. It is.

  As shown in FIGS. 3 and 5, in the manufacturing apparatus 16 of the present embodiment, the second water supply port 68 in the second water supply pipe 62 inserted and fixed in the second insertion hole 78 of the drain pipe 22. An end on the side and the end on the third water supply port 70 side of the third water supply pipe 64 inserted and fixed in the third insertion hole 80 of the drain pipe 22 are provided on the tube wall portion of the drain pipe 22. Since the second and third water supply pipes 62 and 64 are inserted through the second insertion hole 78 and the third insertion hole 80, the central axis Q of the drainage pipe 22 is sandwiched between them. The drain pipe 22 is coaxially arranged on both sides in the radial direction. That is, the end of the second water supply pipe 62 on the second water supply port 68 side and the end of the third water supply pipe 64 on the third water supply port 70 side are center axes of the second water supply pipe 62: T and third. The central axis U of the water supply pipe 64 is positioned so as to be orthogonal to the central axis Q of the drain pipe 22 at one point γ on the central axis Q of the drain pipe 22.

  Accordingly, as shown in FIGS. 6 and 7, the second water supply port 68 and the third water supply port 70 are arranged such that the center line of the flow of water supplied from the second water supply port 68: T ′ and the third water supply The pipe wall portion of the drain pipe 22 so that the central line U ′ of the flow of water supplied from the mouth 70 is perpendicular to the central axis Q of the drain pipe 22 at one point on the central axis Q of the drain pipe 22. Central axis: positions on both sides in the radial direction with Q interposed therebetween, that is, the same position in the axial direction of the tube wall and a position having a phase difference of 180 ° in the circumferential direction of the tube wall (tube wall Are arranged at equal intervals in the circumferential direction of the portion.

  And when manufacturing the several interior component 10 continuously using the manufacturing apparatus 16 made into such a structure, the operation | work is advanced according to the procedure shown below, for example.

  That is, first, a predetermined amount of water is introduced into the water storage tank 42 and stored. This operation is performed only once as a preliminary operation at the beginning of the manufacturing operation of the plurality of interior parts 10. Moreover, the water in the water storage tank 42 is heated to a predetermined temperature by the heater device 43 as necessary.

  Next, the opening / closing valve 44 on the drain pipe 22 is closed, while the opening / closing valve 72 on the water supply pipe 58 and the opening / closing valves 69, 71 on the second and third water supply pipes 62, 64 are opened. At the same time, the water supply pump 56 is operated. As a result, the water in the water storage tank 42 is guided to the water supply pump 56 through the water supply pipe 58 and sent out into the second water supply pipe 62 and the third water supply pipe 64, and in the second water supply pipe 62 and the first water supply pipe 62. The inside of the three water supply pipes 64 is made to flow, and is supplied at the same flow velocity and flow rate into the upper side portion of the drain pipe 22 (drainage channel 45) through the second water supply port 68 and the third water supply port 70.

  At this time, since the formation positions of the second water supply port 68 and the third water supply port 70 on the drain pipe 22 are the special positions as described above, as shown in FIGS. Water flowing from the third water supply ports 68 and 70 into the drain pipe 22 collides with each other on the central axis Q of the drain pipe 22. Then, immediately after the water is supplied from the second and third water supply ports 68 and 70 into the drain pipe 22, the water is supplied from the second and third water supply ports 68 and 70 to the drain pipe 22. The flow of water flowing toward the

  Therefore, when water is supplied through the second and third water supply ports 68, 70, the sub chamber 84 composed of the inner space of the upper portion of the drain pipe 22 with respect to the opening / closing valve 44 and the inner space of the connecting cylinder portion 30. The water is supplied in a state where there is no flow in the radial direction or the circumferential direction of the drain pipe 22, and the sub chamber 84 is accompanied by an increase in the amount of water supplied through the second and third water supply ports 68 and 70. The water inside is gradually and gradually increased. Then, after the sub chamber 84 is filled with water, the water in the sub chamber 84 is supplied into the main chamber 82 of the water tank 18 through the communication port 28.

  Thereafter, when the amount of water in the main chamber 82 of the water tank 18 reaches a preset amount, the open / close valves 69 and 71 on the second and third water supply pipes 62 and 64 are closed. Thus, a predetermined amount of water is stored in the main chamber 82 of the water tank 18.

  As described above, the water supplied from the sub chamber 84 to the main chamber 82 has already lost its flow in the radial direction and the circumferential direction of the drain pipe 22 in the sub chamber 84. Therefore, when water is supplied into the main chamber 82 through the communication hole 28, the radial direction of the cylindrical peripheral wall portion 24 of the water tank 18 positioned coaxially with the drain pipe 22, the flow in the peripheral direction, etc. Will not occur. This effectively eliminates the occurrence of fluctuations in the water surface when water supply into the main chamber 82 is completed. Moreover, in order to suppress the occurrence of such fluctuation of the water surface, the necessity of reducing the water supply speed into the sub chamber 84 and the main chamber 82 by the water supply device 20 can be advantageously eliminated.

  When a predetermined amount of water is stored in the main chamber 82 of the water tank 18, the transfer film 54 is floated on the surface of the stored water 88 in the main chamber 82 as shown in FIG. 8. The transfer film 54 used here has a wood pattern or the like to be formed on the surface of the target interior part 10 on one surface of a water-soluble film 90 made of, for example, polyvinyl alcohol or the like, and is insoluble in water. It has a structure in which the decorative layer 14 is laminated. Such a transfer film 54 is floated on the water surface with the water-soluble film 90 facing downward so that the water-soluble film 90 is immersed in water.

  As described above, when the water supply into the main chamber 82 is completed, the water surface does not fluctuate substantially. Therefore, the operation of floating the transfer film 54 on the water surface in the main chamber 82 is immediately performed after the water supply to the main chamber 82 is completed without waiting for the fluctuation of the water surface to settle. . Then, after the transfer film 54 is floated on the water surface, it is left for a predetermined time. Thereby, the water-soluble film 90 of the transfer film 54 is dissolved in water (swelled and decomposed), and only the decorative layer 14 is floated on the water surface. Further, while the water-soluble film 90 is dissolved in water, a fixing agent or the like is sprayed on the upper surface of the decorative layer 14 as necessary.

  Then, when the water-soluble film 90 is dissolved in water and only the decorative layer 14 is floated on the water surface, as shown by the two-dot chain line and the solid line in FIG. The entire surface of the substrate 12 is submerged in the stored water 88 while pressing the surface portion on which the 12 decorative layers 14 are to be formed against the decorative layer 14 on the water surface. Thereby, the decoration layer 14 is transferred onto the surface of the substrate 12 by water pressure.

  After such a transfer operation is completed, a transfer film comprising a part of the decorative layer 14 that has not been transferred onto the surface of the substrate 12 or a part of the water-soluble film 90 that has not been completely dissolved in the stored water 88. 54 residues 92 remain in the main chamber 82 while floating on the surface of the stored water 88 or in the water. A part of the residue 92 of the transfer film 54 floating in the stored water 88 adheres to or sinks on the inner peripheral surface of the cylindrical peripheral wall portion 24 of the water tank 18, and the bottom wall portion of the water tank 18. It adheres on the inner surface of 26.

  Then, the board | substrate 12 with which the decoration layer 14 was formed in the surface is pulled up from the stored water 88 in the water tank 18, and is dried. Thus, the intended interior part 10 is obtained.

  And if the board | substrate 12 with which the decoration layer 14 was formed was pulled up from the stored water 88 in the water tank 18, the opening-and-closing valve 77 on the 1st water supply pipe 60 will be opened. Thereby, as FIG. 10 shows, water is supplied toward the water surface of the stored water 88 in the main chamber 82 of the water tank 18.

At this time, the opening direction of the first water supply port 66 into the water tank 18 is such that the center line: R ′ of the flow of water supplied from the first water supply port 66 passes through the center point: O of the communication port 28. : X (center axis of the water tank 18: P): β and the central point of the first water supply port 66: a straight line extending horizontally connecting α: S with respect to the circumferential direction of the cylindrical peripheral wall 24 The water supplied from the first water supply port 66 causes the stored water 88 in the water tank 18 to flow along the inner peripheral surface of the cylindrical peripheral wall portion 24 from the direction that intersects with the intersection angle θ _1. , And jetted into the water tank 18. Thereby, a water flow in the circumferential direction is generated in the stored water 88 in the water tank 18.

  Then, after a predetermined time, for example, 1 to 10 seconds elapses from the start of water supply from the first water supply port 66, the opening / closing valve 44 on the drain pipe 22 is opened. As a result, the entire amount of the stored water 88 in the main chamber 82 of the water tank 18 is discharged from the main chamber 82 into the discharge channel 45 through the communication port 28, and provided in the upper portion of the discharge channel 45. Together with the water stored in the sub chamber 84, the water flows into the water storage tank 42 through the drainage channel 45 and is stored. In addition, the time from the start of water supply from the first water supply port 66 to the opening operation of the opening / closing valve 44 reliably causes a circumferential water flow in the stored water 88 in the water tank 18 by the water supply from the first water supply port 66. Sufficient time is set for

  And at the time of discharge | emission of such stored water 88, the whole quantity of the stored water 88 swirls within the water tank 18 by the flow of the circumferential direction which has already arisen in the stored water 88, as shown by the arrow: a in FIG. A flow or vortex is formed and discharged from the communication port 28 into the discharge channel 45 while swirling or swirling. Thus, the decorative layer 14 floating on the surface of the stored water 88 or in the water and the residue 92 of the water-soluble film 90 are discharged together with the stored water 88 from the water tank 18, and the cylindrical peripheral wall 24 of the water tank 18 is also removed. Residue 92 adhering to the inner peripheral surface or the inner surface of the bottom wall portion 26 is also pushed away by the water flow of the stored water 88. Thereby, after the entire amount of the stored water 88 is discharged, the residue 92 remains while remaining on the inner surface of the cylindrical peripheral wall portion 24 and the bottom wall portion 26 of the water tank 18.

  The water supply from the first water supply port 66 into the water tank 18 is stopped by the closing operation of the opening / closing valve 77 on the first water supply pipe 60. This water supply stop is generated by the circumferential flow of the stored water 88. After that, it may be done at any time. However, in order to wash away the inner surfaces of the cylindrical peripheral wall portion 24 and the bottom wall portion 26 of the water tank 18 after discharging the entire amount of the stored water 88, the residue 92 adhering to these inner surfaces is reliably removed from within the water tank 18. Water supply from the first water supply port 66 into the water tank 18 may be continued for a predetermined time from the time when the stored water 88 is completely discharged.

  Then, after the discharge of the entire amount of the stored water 88 in the water tank 18 and the water supply from the first water supply port 66 into the water tank 18 are completed, the opening / closing valve 44 on the drain pipe 22 is closed. Thereafter, the water supply operation into the sub chamber 84 and the main chamber 82, the operation of floating the transfer film 54 on the surface of the stored water 88, and the transfer operation of the decorative layer 14 of the transfer film 54 onto the surface of the substrate 12. Then, the operation of discharging the stored water 88 from the water tank 18 is repeatedly performed according to the procedure as described above, and a plurality of desired interior parts 10 are continuously manufactured.

  As is clear from the above description, when the manufacturing apparatus 16 of the present embodiment is used, when the plurality of interior parts 10 are continuously manufactured, the transfer operation of the decorative layer 14 to the surface of the substrate 12 is performed once. By exchanging the entire amount of the stored water 88 in the water tank 18 every time, all of the residue 92 of the transfer film 54 remaining in the stored water 88 after the transfer work of the decorative layer 14 can be removed from the water tank 18. it can. This effectively prevents the residue 92 from adhering to the transfer film 54 newly floated on the water surface of the stored water 88 when the next transfer operation of the decorative layer 14 is performed. As a result, in a plurality of interior parts 10 that are continuously manufactured, it is extremely advantageous to prevent appearance defects such as wrinkles and deformation of the decorative layer 14 due to adhesion of the residue 92 of the transfer film 54. Can be done.

  Moreover, according to the manufacturing apparatus 16 according to the present embodiment, the water supplied from the second and third water supply ports 68 and 70 by the water supply apparatus 20 into the drain pipe 22 is supplied to the central axis Q of the drain pipe 22. By performing the water supply into the water tank 18 while colliding with each other, it is possible to prevent fluctuations in the water surface of the stored water 88 in the water tank 18 after the water supply into the water tank 18 is completed. Thereby, after the water supply into the water tank 18 is completed, the work of floating the transfer film 54 on the water surface of the stored water 88 can be performed immediately. Moreover, in order to eliminate generation | occurrence | production of the fluctuation | variation of this water surface, reducing the water supply speed | rate into the water tank 18 can also be eliminated advantageously. As a result, the water supply time into the water tank 18 and the time from the completion of water supply into the water tank 18 until the transfer film 54 is floated and set on the water surface can be shortened extremely effectively.

  Therefore, by using the manufacturing apparatus 16 of this embodiment as described above, a plurality of high-quality decorations having a good appearance can be continuously manufactured in a sufficiently short manufacturing cycle time.

  Further, in the present embodiment, the stored water 88 is discharged through the communication port 28 while swirling or swirling, so that after the stored water 88 is drained, the residue 92 of the transfer film 54 is transferred to the water tank 18. Adhering to and remaining on the inner surface of the (cylindrical peripheral wall portion 24 and the bottom wall portion 26) can be effectively prevented. Thereby, when the next transfer operation of the decorative layer 14 is performed, adhesion of the residue 92 to the transfer film 54 newly floated on the water surface of the stored water 88 can be further effectively prevented. Therefore, according to the manufacturing apparatus 16 of this embodiment, continuous production of a plurality of high-quality interior parts 10 having a good appearance can be more reliably performed.

  Furthermore, in the manufacturing apparatus 16 of the present embodiment, the cylindrical peripheral wall portion 24 of the water tank 18 has a cylindrical shape, so that the stored water 88 in the main chamber 82 of the water tank 18 is supplied to the stored water 88 by water supply from the first water supply pipe 60. The swirl flow or vortex flow is more reliably and smoothly generated. Further, the inner peripheral surface of the bottom wall portion 26 of the water tank 18 has a tapered shape with a gradually decreasing diameter toward the communication port 28, so that the stored water 88 in the main chamber 82 of the water tank 18 is swirled. The flow occurs more reliably. Therefore, as a result of these, the attachment of the residue 92 to the cylindrical peripheral wall portion 24 and the bottom wall portion 26 of the water tank 18 can be prevented more reliably.

  In the manufacturing apparatus 16, the end portion of the second water supply pipe 62 that is proximal to the second water supply port 68, and the end portion of the third water supply pipe 64 that is proximal to the third water supply port 70, On the other hand, on-off valves 69 and 71 are provided, respectively. For this reason, when the stored water 88 in the water tank 18 is discharged, the opening and closing valves 69 and 71 are closed so that the residue 92 of the transfer film 54 enters the second water supply pipe 62 and the third water supply pipe 64. And the adhesion of the residue 92 to the inner surface of these 2nd and 3rd water supply pipes 62 and 64 can be prevented advantageously. Also by this, the adhesion of the residue 92 to the transfer film 54 used for the next transfer operation of the decorative layer 14 can be effectively prevented.

  Furthermore, in the manufacturing apparatus 16 of the present embodiment, the sub chamber 84 is configured in the inner space of the upper part of the drainage flow channel 45. Thereby, for example, as compared with the case where the sub chamber 84 is provided separately from the drainage flow channel 45, the entire manufacturing apparatus 16 can be advantageously reduced in size and size.

  In the manufacturing apparatus 16, the water is circulated between the water storage tank 42 and the water tank 18 by the operation of the water supply pump 56. Therefore, it is possible to continuously produce a plurality of interior parts 10 while reusing the water discharged from the water tank 18 and saving the amount of water used. As a result, the manufacture of the intended interior part 10 is achieved. Cost reduction can be advantageously achieved.

  Moreover, in the manufacturing apparatus 16, the upper and lower filtration film devices 46, 48 are provided on the drainage flow path 45, and the water discharged from the water tank 18 is supplied to the upper and lower filtration film devices 46. , 48 after being purified. Accordingly, it is possible to always perform the transfer work of the decorative layer 14 on the substrate 12 using clean water while reusing a predetermined amount of water. As a result, it is possible to advantageously achieve both a good appearance of the manufactured interior part 10 and a reduction in manufacturing cost.

  And in the manufacturing apparatus 16 of this embodiment, the water tank 18 is made detachable with respect to the drain pipe 22 in the connection cylinder part 30. FIG. Therefore, for example, as shown in FIGS. 3 and 11, the water tank 18 includes a main chamber 82 having a small volume (manufacturing apparatus 16 shown in FIG. 3) and a main chamber 82 having a large volume (FIG. 11). The manufacturing apparatus 16) shown in FIG. The water tank 18 is replaced by loosening the bolts of the connection band 40 to cancel the connection state between the water tank 18 and the drain pipe 22 and removing the water tank 18 having a small volume of the main chamber 82 from the drain pipe 22. This can be easily performed by assembling the water tank 18 having a large volume of the chamber 82 to the drain pipe 22 and then tightening the bolts of the connecting band 40 again. In addition, the connection structure of the connection cylinder part 30 and the drain pipe 22 will not be specifically limited if they can be attached or detached. Moreover, when replacing | exchanging the water tank 18, the insertion position in the pipe holder 76 of the 1st water supply pipe 60 and the 1st insertion hole 74 is changed suitably as needed.

  Thereby, for example, when manufacturing the large-sized interior component 10 and the small-sized interior component 10, that is, when manufacturing a plurality of types of interior components 10, the water tank 18 having a size corresponding to the interior component 10 to be manufactured. By properly using these, a plurality of types of interior parts 10 can be advantageously manufactured with only one manufacturing apparatus 16. And, for example, unlike the case where the small-sized interior component 10 is manufactured using the large-sized water tank 18 that can also be used for manufacturing the large-sized interior component 10, the small-sized water tank 18 dedicated to the small-sized interior component 10 is used. By producing the interior part 10, the supply time and discharge time of the stored water 88 in the water tank 18 can be advantageously shortened. As a result, when manufacturing a plurality of types of interior parts 10 having different sizes, shortening of the manufacturing cycle time of the interior parts 10 can be realized more effectively.

  The specific configuration of the present invention has been described in detail above. However, this is merely an example, and the present invention is not limited by the above description.

  For example, water supplied from the second water supply port 68 and the third water supply port 70 into the sub chamber 84 (drainage channel 45) collides with each other in the sub chamber 84, and the second and third water supply ports. Although it is desirable that the flow of water from 68 and 70 into the sub chamber 84 be eliminated, the flow of water does not necessarily have to be zero. The second and third water supply ports 68, so as to prevent as much as possible the occurrence of fluctuations in the water surface in the seed chamber 82 upon completion of water supply into the main chamber 85 (water tank 18) through the communication port 28. It is only necessary that the flow of water from 70 into the sub chamber 84 is reduced.

  Therefore, the second water supply port 68 and the third water supply port 70 are connected to the pipe wall portion of the drain pipe 22 with the center line of the flow of water supplied from the second and third water supply ports 68 and 70: T ′, Position where U ′ intersects at two points instead of γ: one point on the central axis: Q of the drain pipe 22 (position where the central axis intersects at two or more points different from each other when there are three or more water supply ports) ), And may be provided so as to be located at different locations in the central axis: Q direction of the drain pipe 22. That is, the second water supply port 38 and the third water supply port 70 cause the water supplied from these water supply ports 68 and 70 to collide in the sub chamber 84, and the flow of the water becomes small in the sub chamber 84. Thus, with respect to the pipe wall portion of the drainage pipe 22, the center lines: T ′, U ′ of the water flow from the respective water supply ports 68, 70 are provided at positions intersecting with the central axis: Q of the drainage pipe 22. It only has to be done.

  And although the number of water supply pipes, the installation position of the water supply port with respect to the drainage pipe 22, or the inner diameter of the water supply port can be changed as appropriate, they are supplied into the sub chamber 84 (drainage channel 45). It is necessary for the water to collide with each other on the central axis Q in the drain pipe 22 so that the flow of the water is reduced. Hereinafter, another embodiment in which the number of water supply pipes, the installation position of the water supply port with respect to the drain pipe 22, the inner diameter of the water supply port, and the like are different from those of the first embodiment will be described with reference to FIGS. However, with respect to those embodiments, members and parts having the same structure as those of the first embodiment shown in FIGS. 2 to 5 are denoted by the same reference numerals as those of FIGS. The detailed description is omitted. The same applies to an embodiment shown in FIG. 14 described later.

For example, the embodiment shown in FIG. 12 has a fourth water supply pipe 94 having the same inner diameter as the second and third water supply pipes 62, 64 in addition to the second water supply pipe 62 and the third water supply pipe 64. Yes. In such an embodiment, the second, third, and fourth water supply pipes 68, 70, 98 side ends of the second, third, and fourth water supply pipes 62, 64, 94 are connected to the drain pipe 22.

Specifically, the intersection angles: θ ₅ and θ ₆ are set so as to satisfy the following formulas (1) and (2).

M = N cos θ ₅ + L cos θ ₆ (1)
Nsin θ ₅ = L sin θ ₆ (2)
Where M is the amount of water supplied from the second water supply port
N: Amount of water supplied from the third water inlet
L: Amount of water supplied from the 4th water supply port

  Accordingly, the second, third, and fourth water supply ports 68, 70, 98 of the second, third, and fourth water supply pipes 62, 64, 94 are supplied from the respective water supply ports 68, 70, 98. The central line of the water flow: T ′, U ′, V ′ is a central point of the drain pipe 22: one point on the Q: γ, the central axis: orthogonal to the Q, and different from each other in the circumferential direction of the drain pipe 22 They are arranged at a predetermined interval. In this embodiment, water supplied from the second, third, and fourth water supply ports 68, 70, 98 to the drain pipe 22 at the same flow rate is the central axis in the drain pipe 22. : It is made to collide with each other on Q, and the flow of those waters is lost.

  The water supply speeds from the second, third, and fourth water supply ports 68, 70, and 98 may be different from each other. Even in this case, the water supplied from each of the water supply ports 68, 70, and 98 is caused to collide with each other at a portion other than the central axis Q in the drain pipe 22, and the flow of the water. The circumferential position of the drainage pipe 22 of the second, third, and fourth water supply ports 68, 70, and 98 is appropriately set so that is reduced or eliminated.

  Moreover, in the said some embodiment, although the subchamber 84 was comprised in the inner side space of the upper side part of the drainage flow path 45, it is also possible to provide the subchamber 84 separately from the drainage flow path 45. It is. For example, as shown in FIG. 14, the bottom wall portion 26 of the water tank 18 is provided with a first series opening 102 and a second communication opening 104, and the drain pipe 22 is provided in the first series opening 102. Are connected in a communication state, and a bottomed cylindrical sub-chamber forming tube portion 106 is connected to the second communication port 104 in a communication state. And the 2nd water supply pipe 62 and the 3rd water supply pipe 64 are made into the lower end part of this cylinder part 106 for subchamber formation, the 2nd and 3rd water supply pipes 62 in manufacturing apparatus 16 concerning the first embodiment, The connection is made in the same structure as the connection structure to the 64 drain pipes 22. Thus, the sub chamber 84 is configured in the inner space of the sub chamber forming cylinder portion 106. In addition, the second communication port 104 is an open / close made of, for example, an electromagnetic valve, which switches the inner space of the sub chamber forming cylinder portion 106 and the inner space of the main chamber 82 of the water tank 18 between a communication state and a non-communication state. A valve 108 is provided.

  According to such a structure, after supplying a predetermined amount of water into the main chamber 82, the opening / closing valve 108 is closed so that the residue 92 of the transfer film 54 generated in the subsequent transfer operation is transferred into the sub chamber 84. Intrusion is prevented. As a result, it is more effective that the residue 92 is mixed into the stored water 88 that is supplied from the sub chamber 84 to the main chamber 82 and stored for the next transfer operation. Can be blocked.

  Further, when the sub chamber 84 is provided separately from the drainage channel 45, the sub chamber 84 may be configured in a space that is surrounded by the peripheral wall portion and communicates with the communication port 28. Therefore, for example, the sub chamber 84 can be configured in an inner space such as a housing that communicates with the communication port 28.

  As is clear from FIG. 14, the first series of through holes 102 (communication holes 28) constituting the drainage port are not necessarily arranged coaxially with the water tank 18. Further, the sub chamber 84 may not be arranged coaxially with the water tank 18.

  Furthermore, the cylindrical peripheral wall portion 24 of the water tank 18 does not necessarily have a cylindrical shape, but when the stored water 88 is discharged, the inner peripheral surface shape is such that a swirling flow and a vortex flow are reliably formed. It is desirable to have a cylindrical shape with no corners. Accordingly, the cylindrical peripheral wall portion 24 is preferably a cylindrical shape having a cross-sectional shape of an ellipse or an ellipse in addition to a cylindrical shape.

  Furthermore, the shape of the bottom wall portion 26 of the water tank 18 is not particularly limited, and may be a planar shape instead of the illustrated tapered shape.

  A plurality of first water supply pipes 60 that supply water directly into the main chamber 82 may be provided. In that case, it is desirable that the plurality of first water supply pipes 60 are provided so that the respective first water supply ports 66 are positioned at intervals in the circumferential direction of the cylindrical peripheral wall portion 24. As a result, when the stored water 88 is discharged, the swirling flow or swirl of the stored water 88 is more reliably formed.

  Furthermore, a shielding member that blocks the flow of water supplied from the water supply port to the main room is installed in a portion located between the water supply port arrangement portion and the communication port in the sub chamber, or in the communication port. Thus, it is possible to eliminate such water flow. As this shielding member, a plate material installed so as to block most of the communication hole, a portion located between the water supply port arrangement portion and the communication port in the sub chamber, and a water supply port arrangement portion in the sub chamber The mesh member etc. which are installed so that the part located between and the communication port and all the communication holes may be plugged up are used. This also eliminates the flow of water in the main chamber, and can advantageously prevent water surface fluctuations immediately after the completion of water supply.
