Description

Fluid pressurization device

The present invention relates to a fluid pressure conveying device.

Conventionally, a pumping device disclosed in Patent Document 1 below, etc., has been suitably used, for example, for pumping a high-viscosity fluid. The pumping device of Patent Document 1 below has a single-axis eccentric screw pump, and can pump a fluid having a high viscosity or other characteristics that make it difficult to pump using other pumps, while minimizing pulsation and at a desired discharge amount.

Japanese Patent Publication No. 2008-267307

In the pumping device of the above-described patent document 1, the fluid to be pumped is contained in a bag, and can be set in a container provided by the pumping device. Here, the inventors of the present invention have carefully examined and have reached the finding that in cases where the bag containing the fluid to be pumped has a fluid containing portion and a fluid non-containing portion, there are cases where it becomes difficult to pump the fluid from the bag until the remaining amount is sufficiently reduced.

Therefore, the present invention has as its object the provision of a fluid transport device capable of pumping and transporting fluid from a bag until the residual amount is sufficiently reduced, even if the bag containing the fluid to be pumped has a fluid receiving portion and a fluid non-receiving portion.

(1) In order to solve the above-described problem, the fluid pressure-transport device of the present invention is provided, which comprises a container that accommodates a pocket containing a fluid, a plate that is loaded on the pocket inside the container, and a pump that sucks the fluid accommodated in the pocket, wherein the fluid can be pressure-transported by sucking the fluid by the pump through an opening formed in the pocket while applying a pressing force to the pocket through the plate, and has a sheet portion that is arranged on the bottom side of the container and can form a storage space portion, and wherein the pocket has a fluid receiving portion and a fluid non-receiving portion and is accommodated in the container so that the fluid non-receiving portion can be accommodated in the storage space portion.

The fluid pressure transfer device of the present invention is capable of suctioning and pumping the fluid by a pump through an opening formed in the pocket while applying a pressure force to the pocket through the plate while placing a pocket containing a fluid inside a container and arranging a plate on the pocket. Here, in the fluid pressure transfer device of the present invention, a sheet portion provided on the bottom side of the container can form a storage space portion capable of accommodating a fluid non-receiving portion in the pocket where no fluid is contained. Therefore, the fluid pressure transfer device of the present invention can suppress the non-fluid receiving portion from being obstructed when, for example, applying a pressure force to the pocket by a plate or sucking the fluid by a pump is performed by accommodating a portion forming the non-fluid receiving portion in the pocket in the storage space portion. Therefore, according to the present invention, even if a liquid is set in a container in a state where it is contained in a pocket having a fluid receiving portion and a non-fluid receiving portion, it is possible to provide a fluid pressure transfer device capable of pumping and pumping the fluid from the pocket until the remaining amount is sufficiently small.

(2) The fluid pressure device of the present invention described above may have the storage space portion provided in the central portion of the sheet portion.

With this configuration, the fluid-non-receiving portion can be accommodated in the storage space portion while the pockets can be arranged in a well-balanced manner inside the container. As a result, the fluid-non-receiving portion can be further prevented from being obstructed, for example, by applying a pressure force to the pocket by a plate or sucking the fluid by a pump, and the remaining amount of fluid pumped in the pocket can be minimized.

(3) The fluid pressure transfer device of the present invention described above may be such that the container and the suction port move relative to each other so that the suction port of the pump approaches the bottom of the container in conjunction with a decrease in the remaining amount of liquid, and the sheet portion may be concave in a beveled shape toward a position facing the suction port.

According to this configuration, the liquid contained in the pocket tends to gather toward a position on the extension of the relative movement direction of the container and the suction port with respect to the suction port of the pump, and thus becomes easier to suck by the pump. As a result, the pumping efficiency of the liquid contained in the pocket can be further improved.

(4) The fluid pressure device of the present invention described above may be such that the container and the suction port move relative to each other so that the suction port of the pump approaches the bottom of the container in conjunction with a decrease in the remaining amount of liquid, and the storage space portion may be provided on an extension of the direction of relative movement of the container and the suction port with respect to the suction port.

In the fluid pressure transfer device of the present invention, for example, due to the influence of a pressing force acting from the plate to the pocket, the fluid contained in the fluid receiving portion of the pocket tends to gather toward the non-fluid receiving portion. Furthermore, in the fluid pressure transfer device of the present invention, a receiving space portion is provided on an extension of the relative movement direction of the container and the suction port with respect to the suction port, and the fluid collected on the non-fluid receiving portion side can be smoothly sucked and sent. Therefore, according to the fluid pressure transfer device of the present invention, even if the fluid is prepared inside the container in a state of being contained in a pocket having a fluid receiving portion and a fluid non-receiving portion, the fluid can be pumped from the pocket until the remaining amount is sufficiently reduced and sent.

Here, as described above, when a pressure force is applied to the pocket by the plate loaded on the pocket inside the container and the fluid is sucked from the pocket, as the suction of the fluid progresses, the empty portion (void portion) of the fluid receiving portion gradually increases due to the fluid being sucked. If the void portion of the fluid receiving portion exists between the fluid remaining in the fluid receiving portion and the plate, for example, as the void portion increases, it may become difficult for the pressure force by the plate to be applied to the fluid, which may affect the suction efficiency of the fluid or the residual amount of fluid that is not completely sucked, etc. Therefore, in the fluid pressure transfer device of the present invention described above, even if the void portion of the fluid receiving portion is formed, it is desirable to minimize the influence on the suction efficiency of the fluid or the residual amount of suction.

(5) Based on this knowledge, the fluid pressure device of the present invention may be configured such that a peripheral space is formed between the outer surface of the sheet portion and the inner surface of the container, extending in the axial direction of the container and open toward an area where the pocket is accommodated.

According to this configuration, even if a void portion is formed in the fluid receiving portion as the fluid is sucked in progress, the void portion can be relieved in the peripheral space formed between the outer surface of the sheet portion and the inner surface of the container. As a result, it is possible to minimize the decrease in the fluid sucking efficiency accompanying the presence of the void portion formed in the fluid receiving portion, or the increase in the residual amount of fluid that is not completely sucked in.

(6) The fluid pressure transfer device of the present invention described above may have an adapter that can be inserted into the storage space, and the adapter can be mounted on the fluid non-receiving portion while keeping the fluid non-receiving portion bound.

According to this configuration, for example, when accommodating a pocket in a container, the non-fluid-receiving portion is tied, the adapter is mounted relative to the non-fluid-receiving portion, and the adapter is inserted while accommodating the fluid-receiving portion in the storage space, thereby positioning the non-fluid-receiving portion with high precision relative to the storage space. This makes it possible to suppress the non-fluid-receiving portion from interfering with the suction of the fluid, and to minimize the remaining amount of fluid pumped in the pocket.

(7) The fluid pressure device of the present invention described above may be configured such that the pocket is formed into a rod shape by tying the fluid non-receiving portion, and the rod-shaped portion is accommodated in the container with the portion facing the bottom of the container.

According to the fluid pressure transfer device of the present invention, even if the fluid is contained in a bag formed into a rod shape by tying together a fluid non-receiving portion, the fluid can be pumped and transferred from the bag until the remaining amount is sufficiently reduced.

According to the present invention, even if a bag containing a fluid to be pumped has a fluid receiving portion and a fluid non-receiving portion, a fluid sending device capable of pumping and sending the fluid from the bag until the residual amount is sufficiently reduced can be provided.

Hereinafter, a fluid pressure sending device (10) according to one embodiment of the present invention will be described in detail with reference to the drawings. In the following description, after describing the configuration of the fluid pressure sending device (10), the operation of the fluid pressure sending device (10) will be described.

≪About the composition of the fluid pressure device (10)≫

As illustrated in Fig. 1, the fluid pressure sending device (10) is schematically provided with a container (20), a sheet portion (30), a plate (50), a scraper (60), a pump (70), and an elevating device (90). The fluid pressure sending device (10) is configured to be capable of sucking and sending fluid from the bag (100) by applying a pressure force to the bag (100) by means of the plate (50) and the scraper (60) arranged on the bag (100) by setting a bag (100) containing fluid inside the container (20). In addition, the fluid pressure sending device (10) is configured to be capable of elevating the pump (70) by means of the elevating device (90) depending on the remaining amount of fluid. Hereinafter, the configuration of each part of the fluid pressure sending device (10) will be described in more detail.

The container (20) may be, for example, a bottomed cylindrical shape such as a so-called pail can or drum can, or a cylindrical shape that penetrates in the vertical direction. In the present embodiment, a bottomed cylindrical shape is used as the container (20). The container (20) is settable by introducing a pocket (100) into which a fluid enters the interior through an open portion provided on the other axial end, with a closed portion on one axial side as the bottom. In the fluid pressure device (10), the container (20) can be placed at a position adjacent to the support (92) on the lower side of the support (92) forming the lifting device (90).

Here, the pocket (100) accommodated inside the container (20) is formed using a film made of a resin material such as polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), nylon (NY), cellophane (PT), etc. As illustrated in FIG. 12, the pocket (100) is provided in a sealed state by accommodating a fluid. The pocket (100) has a fluid receiving portion (102) (a diagonal portion in the drawing) and a fluid non-receiving portion (104). The fluid receiving portion (102) is an area in the pocket (100) where the fluid to be conveyed is accommodated. In addition, the fluid non-receiving portion (104) is a portion that is sealed or the like without accommodating a fluid.

The pocket (100) may be provided in any form, but may be, for example, sealed by heat sealing the portion forming the non-fluid-receiving portion (104), sealed by binding the portion forming the non-fluid-receiving portion (104) using a caulking member, sealed by binding the portion forming the non-fluid-receiving portion (104) by winding tape or the like around the portion forming the non-fluid-receiving portion (104) into a rod shape, etc. That is, the pocket (100) has a sealing portion (105) in the non-fluid-receiving portion (104) that is sealed by binding using a heat seal, a binding band, a rubber band, a tape, a string, wire, a caulking member, etc. Since the pocket (100) is sealed in the sealing portion (105) provided in the fluid-non-receiving portion (104) in this way, even if the fluid-non-receiving portion (104) is directed toward the bottom of the container (20) and the fluid is introduced into the interior of the container (20) through the opening portion formed at the top of the container (20), the fluid does not leak out of the pocket (100). In addition, there are cases where the fluid contained in the pocket (100) is, for example, a high viscosity fluid and thus does not change into a shape that follows the shape of the fluid-receiving portion (102) simply by introducing it into the container (20). In such cases, the pocket (100) is made shape-changeable by performing a process such as rolling it on the bottom surface before introducing it into the interior of the container (20) to make the shape of the fluid-receiving portion (102) even so that it enters the interior of the container (20).

In addition, the fluid contained in the pocket (100) is not limited to, for example, a low viscosity liquid with low viscosity, and may be, for example, a high viscosity liquid with high viscosity. In addition, the fluid may be, for example, a moisture-curing adhesive containing a material such as a cyanoacrylate type or a silicone rubber type, which hardens by reacting with moisture in the air, an anaerobic-curing adhesive containing a material such as an acrylate type (acrylic resin type), which hardens by blocking air, an ultraviolet-curing adhesive containing a material such as an acrylic resin type or an epoxy type, which hardens by irradiating ultraviolet rays, etc.

As shown in FIG. 1 or FIG. 2, etc., the sheet portion (30) is a member that is placed on the bottom side inside the container (20). As shown in FIG. 3, etc., the sheet portion (30) has a sheet portion body (34) and an adapter (36) and forms a storage space portion (35).

As illustrated in FIG. 1 or FIG. 2, the sheet body (34) is a portion that serves as a sheet of a pocket (100) inside the container (20). The sheet body (34) has a height lower than the height of the container (20). Therefore, when the sheet body (34) is placed inside the container (20), a pocket receiving space (22) capable of accommodating the pocket (100) is formed above the sheet body (34). In addition, the outer diameter of the sheet body (34) is smaller than the inner diameter of the container (20). Therefore, when the sheet body (34) is placed inside the container (20), a peripheral space (38) is formed between the outer peripheral surface (34a) of the sheet body (34) and the inner peripheral surface (20a) of the container (20). The peripheral space (38) extends in the axial direction (up-down direction in the illustrated example) of the container (20) and is open toward the pocket receiving space (22) located above the sheet body (34).

As illustrated in Fig. 3, the sheet main body (34) has a concave shape with a ceiling surface (34b) (surface on the side of the pocket receiving space (22)). That is, the sheet main body (34) is formed so that it slopes downward from a predetermined position on the outer side in the radial direction (in this embodiment, a middle position in the radial direction) toward the center over the entire circumference. The sheet main body (34) is provided with a storage space (35) capable of storing a fluid-free portion (104) of a pocket (100). The storage space (35) is formed so as to open toward the pocket receiving space (22) side on the ceiling surface (34b) of the sheet main body (34). The storage space (35) exists on an extension of the relative movement direction of the container (20) and the suction port (76x) with respect to the suction port (76x) of the pump (70) which will be described in detail later. The storage space (35) is formed as a hollow body extending in the axial direction (up-down direction in the illustrated state) of the container (20). In the present embodiment, the storage space (35) is formed as a through hole penetrating the sheet body (34). At the opening end (the end on the pocket receiving space (22) side) of the storage space (35), a step portion (35a) formed in a step shape is provided so that a flange portion (36b) of an adapter (36), which will be described in detail later, can be inserted.

The adapter (36) is a member that can be inserted and fitted into the storage space (35) provided in the sheet body (34) from the pocket receiving space (22) side. The adapter (36) is a member that has a barrel (36a) and a flange (36b) and an insertion through hole (36c) at an axial position. The barrel (36a) is a portion of the storage space (35) formed in a substantially barrel shape. The barrel (36a) can be inserted and fitted into the storage space (35) of the sheet body (34) substantially without a gap. The flange (36b) is a portion that protrudes radially outward on one end side of the barrel (36a) in the axial direction. The flange (36b) can be fitted into the stepped portion (35a) of the storage space (35) described above. The insertion through hole (36c) is formed by a through hole penetrating in the axial direction of the adapter (36). As shown in FIG. 1 or FIG. 2, etc., the adapter (36) can be mounted on the pocket (100) by inserting and penetrating the portion that binds the fluid-receiving portion (104) of the pocket (100) into the insertion through hole (36c).

As illustrated in FIG. 2, the plate (50) is a roughly disk-shaped body having a constant thickness. The plate (50) is placed on the fluid introduced into the inside of the container (20) in a pocket (100) by means of a scraper (60) which will be described in detail later. The plate (50) may be formed of a synthetic resin such as polyethylene, polystyrene, or polypropylene, or a material such as rubber, for example. In addition, the plate (50) may be formed of a flexible material such as a non-foaming resin material, or an independent cell body such as foamed polyethylene or foamed synthetic rubber. The plate (50) has an outer diameter that is slightly smaller than the inner diameter of the container (20).

The plate (50) has a shape in which the lower surface (50a) corresponds to the ceiling surface (34b) of the sheet body (34). Specifically, the lower surface (50a) is formed so that it slopes downward from a predetermined position (in the present embodiment, a middle position in the radial direction) on the outer radial side to the center side over the entire circumference of the plate (50). As a result, the plate (50) has a shape in which a protrusion (52) protrudes in a truncated cone shape on the lower surface (50a) side.

A mounting hole (54) is formed in approximately the center of the radial direction of the plate (50). The mounting hole (54) penetrates in the thickness direction of the plate (50). The mounting hole (54) has a tapered shape corresponding to the suction port (76x) of the pump (70), which will be described in detail later. By inserting the suction port (76x) of the pump (70) into the mounting hole (54), the two are fitted together, and the plate (50) and the pump (70) are removably connected. In addition, the connecting portion of the plate (50) and the pump (70) may be sealed by interposing a sealing member, such as an O-ring, between the two.

The scraper (60) has an annular portion (62) and a curved portion (64). The annular portion (62) is an annular and plate-shaped portion. The outer diameter of the annular portion (62) is approximately the same as or slightly smaller than the inner diameter of the container (20). Therefore, when the scraper (60) is placed in the container (20) in a posture in which the annular portion (62) is approximately parallel to the bottom surface of the container (20), almost no gap is formed between the inner surface (20a) of the container (20) and the outer edge of the annular portion (62). In addition, the annular portion (62) has an opening (66) at the center side in the radial direction. The opening (66) is opened to a size in which the protrusion (52) of the plate (50) described above can be inserted.

The bent portion (64) is a portion in which the outer edge of the annular portion (62) is bent in the thickness direction of the scraper (60). The bent portion (64) is a portion that extends along the inner peripheral surface (20a) of the container (20) when the scraper (60) is positioned so that the annular portion (62) is approximately parallel to the bottom surface of the container (20). When the fluid pressure device (10) is used, the scraper (60) is positioned so that the bent portion (64) faces the bottom surface of the container (20) and the annular portion (62) is placed on a pocket (100) introduced into the container (20).

The pump (70) is for sucking and pumping the fluid contained in the bag (100) set in the container (20). The pump (70) is a rotary displacement pump. In the present embodiment, a single-axis eccentric screw pump as illustrated in Fig. 4 is used as the pump (70). The pump (70) has a rotor (72) of a male screw type that receives power and rotates eccentrically, and a stator (74) whose inner surface is formed into a female screw type. The pump (70) is configured to have a pump mechanism (75) whose main part is formed by the rotor (72) and the stator (74) built into a pump casing (76).

The rotor (72) is a metal shaft having an n-1 (n ≥ 2: in this embodiment, n = 2) male screw shape. The rotor (72) is formed so that its cross-sectional shape is approximately circular when viewed in cross-section at any position in the longitudinal direction. The stator (74) is a member having an approximately cylindrical shape and an inner circumferential surface formed in an n-set (in this embodiment, n = 2) female screw shape. The through hole (80) of the stator (74) is formed so that its cross-sectional shape (opening shape) is approximately elliptical when viewed in cross-section at any position in the longitudinal direction of the stator (74).

The rotor (72) is inserted into the through hole (80) formed in the stator (74) described above, and is freely rotatable eccentrically within the through hole (80). The end of the rotor (72) on the base side is connected to a motor (86) as a driving source through an eccentric rotating member (85). The eccentric rotating member (85) is a part that connects the drive shaft connected to the motor (86) side and the rotor (72) so that power can be transmitted, and is configured by a conventionally known universal joint or the like.

When the rotor (72) is inserted into the stator (74), the outer surface of the rotor (72) and the inner surface of the stator (74) come into close contact at the tangent line between the two, thereby forming a fluid return path (82) (cavity). The fluid return path (82) is formed to extend in a spiral shape in the longitudinal direction of the stator (74) or the rotor (72).

The pump casing (76) is made of metal and has an end stud (76c) installed through a stay bolt (76b) on one end of the longitudinal direction of the casing body (76a) in the shape of a cylinder. In the pump casing (76), a pump mechanism (75) whose main part is composed of a rotor (72) and a stator (74) is fitted between the casing body (76a) and the end stud (76c). The casing body (76a) is provided with a nipple (76d) that is arranged to communicate with the internal space of the pump casing (76) and a plug (76e) mounted thereon. The plug (76e) is installed to close the nipple (76d) during normal operation, but for example, after setting a pocket (100) or plate (50) in a container (20), the plug (76d) can be removed appropriately to open the nipple (76d) to remove remaining air from the lower side (the pocket (100) side) of the plate (50) or inside the pump (70).

The pump (70) can advance the fluid return path (82) in the longitudinal direction within the stator (74) by rotating the rotor (72) within the through hole (80) of the stator (74). Therefore, by rotating the rotor (72), it is possible to suck viscous liquid from one end of the stator (74) into the fluid return path (82) and transport it toward the other end of the stator (74). In addition, by switching the rotational direction of the rotor (72), the direction of progression of the fluid return path (82) can be switched. In the present embodiment, the rotational direction of the rotor (72) is regulated so that, in a normal use state, the opening formed in the end stud (76c) in the pump casing (76) can function as a suction port (76x), and the opening formed on the outer peripheral surface of the casing body (76a) can function as a discharge port (76y). In addition, the end stud (76c) has a portion that functions as a suction port (76x) in a tapered shape corresponding to the mounting hole (54) of the plate (50) described above.

As illustrated in Fig. 1, the pump (70) is fixed to the arm (94) of the lifting device (90) in a posture in which the suction port (76x) formed at the end of the end stud (76c) faces downward. Therefore, by arranging a container (20) containing a viscous liquid below the arm (94) and operating the arm (94) in the up-and-down direction, the suction port (76x) of the pump (70) can be moved relative to the container (20) in the axial direction (height direction) within the container (20).

As illustrated in FIG. 1, the lifting device (90) has a support (92), an arm (94), and the like. The support (92) is installed standing upright in the vertical direction. An lifting mechanism (not illustrated) is built into the inside of the support (92). The arm (94) is installed so as to protrude toward the side of the support (92). The pump (70) described above is installed on the arm (94) in a posture in which the suction port (76x) faces downward and extends up and down along the support (92). When the container (20) is placed at a predetermined position with the pump (70) installed on the arm (94), the axial positions of the opening area of the container (20) and the opening area of the suction port (76x) are approximately aligned, as indicated by the dashed line in the drawing. For this reason, the lifting device (90) can change the height of the suction port (76x) relative to the container (20) in the up-and-down direction at the axial position of the container (20) and the suction port (76x) by operating the lifting mechanism to raise and lower the arm (94). The lifting device (90) can lower the pump (70) so that the suction port (76x) approaches the bottom of the container (20) in conjunction with a decrease in the remaining amount of the fluid contained in the container (20).

≪About the operation of the fluid pressure device (10)≫

Next, the operation of the fluid pressure transfer device (10) will be described. When a fluid is pressure-transported using the fluid pressure transfer device (10), as illustrated in FIG. 1, the fluid is first introduced into the container (20) in the state in which it is contained in the bag (100). At this time, a sheet portion (30) is placed inside the container (20). On the other hand, if the bag (100) is in a form that does not fit into the container (20), the bag (100) is appropriately rolled on a floor surface or the like to align the shapes of the bag (100) and the fluid so that the bag (100) can be placed inside the container (20). In addition, an adapter (36) is mounted on the fluid non-receiving portion (104) of the bag (100). Thereafter, the fluid-receiving portion (104) side is set to face the bottom side of the container (20), the pocket (100) is introduced into the container (20), and placed on the sheet body (34), while the fluid-receiving portion (104) and the adapter (36) are inserted into the storage space (35) provided approximately at the center of the sheet body (34). As a result, as illustrated in Fig. 1, the pocket (100) is accommodated inside the container (20) in a position where the fluid-receiving portion (102) faces the opening side (upper side in the illustrated state) of the container (20).

As described above, after introducing the pocket (100) into the container (20), an opening (106) for serving as an insertion port for the suction port (76x) of the pump (70) is formed in the pocket (100) as shown in FIG. 5 or FIG. 10. The opening (106) is formed along the outer diameter of the suction port (76x) in the fluid receiving portion (102) of the pocket (100) at the axial position of the container (20). The opening (106) can be formed, for example, by cutting the pocket (100) with a blade (110) or the like. In addition, in order to form the opening (106) at a predetermined position and a predetermined size, it may be formed by appropriately measuring the dimensions or the like, but for example, an auxiliary plate or a mold for forming the opening (106) may be separately prepared and the opening may be formed using this.

When an opening (106) is formed in the pocket (100), a scraper (60) is placed on the pocket (100). The scraper (60) is placed in a position such that the annular portion (62) is approximately parallel to the bottom surface of the container (20) and the curved portion (64) protrudes toward the bottom surface of the container (20). In addition, when the scraper (60) is placed on the pocket (100), a plate (50) is placed on the scraper (60). The plate (50) is placed such that the protrusion (52) enters the opening (66) formed in the scraper (60) while the lower surface (50a) faces the scraper (60).

As described above, when the scraper (60) and the plate (50) are arranged on the bag (100), the pump (70) is connected to the plate (50). Specifically, as shown in FIG. 6, when the plate (50) is arranged on the scraper (60), the pump (70) is lowered to the container (20) side by the lifting device (90), and the suction port (76x) is inserted into the mounting hole (54) of the plate (50). As a result, as shown in FIG. 7, the pump (70) and the plate (50) are connected, and the state is ready for sucking and sending the fluid in the bag (100) by the fluid pressure device (10).

As described above, when the preparation of the fluid pressure transfer device (10) is completed, the pump (70) can be operated to suck and pump the fluid from the bag (100). As illustrated in FIG. 8, when the fluid pressure transfer device (10) proceeds with sucking and pumping the fluid, the lifting device (90) is operated accordingly, and the pump (70) moves toward the bottom side of the container (20) (downward in the illustrated example). Along with the movement of the pump (70), the plate (50) and the scraper (60) also move (downward in the illustrated example). As the plate (50) moves, a compressive force is applied to the bag (100). In addition, as the scraper (60) moves, the excess portion of the pocket (100) generated by the suction of the fluid is pressed by the curved portion (64) of the scraper (60), and a wrinkle-shaped portion (108) is formed along the inner surface (20a) of the container (20). In addition, as the suction and pressure of the fluid progress, the wrinkle-shaped portion (108) is pressed into the peripheral space (38) formed between the sheet portion (30) and the container (20), as shown in FIG. 9. As a result, the excess portion of the pocket (100) generated by the suction of the fluid becomes the wrinkle-shaped portion (108) and is accommodated in the peripheral space (38). Therefore, even if the excess portion is formed in the pocket (100) by the suction of the fluid, the suction of the fluid by the pump (70) can be continued while applying a pressure force to the pocket (100) by the plate (50). As the fluid suction progresses in this manner, as shown in FIG. 9 or FIG. 10, the plate (50) soon reaches the vicinity of the bottom of the container (20), and the fluid suction ends.

As described above, the fluid pressure transfer device (10) of the present embodiment is configured to be capable of suctioning and pressure-transferring a fluid by a pump (70) through an opening (106) formed in the pocket (100) while applying a pressure force to the pocket (100) through the plate (50) while introducing the pocket (100) into the container (20) and arranging the plate (50) on the pocket (100). In addition, in the fluid pressure transfer device (10), a sheet portion (30) is provided on the bottom side of the container (20), and a storage space portion (35) is provided so as to be opened at approximately the center portion (approximately the center position) of the sheet portion (30). In this way, by introducing the bag (100) into the container (20) with the fluid receiving portion (102) facing the opening end side of the container (20) and the fluid non-receiving portion (104) facing the bottom side of the container (20), the fluid non-receiving portion (104) can be received in the storage space (35). Because of this configuration, in the fluid pressure device (10), when applying a pressure force to the bag (100) by the plate (50) or sucking the fluid by the pump (70), the fluid non-receiving portion (104) can be prevented from becoming an obstacle.

To explain in more detail, for example, in the case where a sheet portion (130) that does not have a storage space portion (35) instead of the sheet portion (30) described above is used in the fluid pressure device (10), even if the fluid is sucked to a state where there is almost no gap between the end portion on the suction port (76x) side of the pump (70) and the fluid non-receiving portion (104) of the bag (100) as shown in Fig. 11, a considerable amount of fluid will remain on that side. However, as shown in the embodiment above, by loading the bag (100) on the ceiling surface (34b) of the sheet portion (30) and configuring the fluid non-receiving portion (104) to be able to be relieved downward (toward the bottom side of the container (20)) from the ceiling surface (34b), it is possible to suppress the fluid non-receiving portion (104) from interfering with the suction of the fluid. Therefore, according to the fluid pressure transfer device (10), the fluid contained in the container (20) can be pumped and pressure transferred until the remaining amount is sufficiently reduced.

In addition, unlike the case where the fluid is contained in the pocket (100) up to the vicinity of the binding portion (105) as shown in (a) of Fig. 12, it is assumed that the fluid is contained only to a portion slightly away from the binding portion (105) as shown in (b) of Fig. 12, and thus a surplus portion (107) is formed between the binding portion (105) and the liquid level. When such a pocket (100) is used, the storage space portion (35) may be formed in a size or shape that can contain the surplus portion (107) in addition to the binding portion (105) formed in the fluid non-receiving portion (104). Accordingly, even when a pocket (100) with a surplus portion (107) is used, it becomes possible to pump and transfer the fluid until the remaining amount is sufficiently reduced.

In addition, as described above, the fluid pressure sending device (10) has the storage space (35) provided in the central portion of the seat portion (30). Therefore, the fluid pressure sending device (10) can accommodate the fluid non-receiving portion (104) in the storage space (35) while arranging the pocket (100) in a well-balanced manner inside the container (20). In addition, in the present embodiment, an example is shown in which the storage space (35) is arranged in a substantially cylindrical shape in the central portion (approximately at the center of the axis) of the seat portion (30), but the arrangement or shape of the storage space (35) may be appropriately changed, for example, depending on the shape or position of the fluid non-receiving portion (104).

As described above, the fluid pressure device (10) has a shape in which the ceiling surface side of the seat portion (30) is concave in a cone shape toward a position facing the suction port (76x) of the pump (70). Therefore, the liquid contained in the pocket (100) is more likely to gather even slightly toward the area on the extension line of the suction port (76x) of the pump (70), and is thus more likely to be sucked by the pump (70). As a result, the pumping efficiency of the liquid contained in the pocket (100) can be further improved. In addition, in the present embodiment, an example in which the ceiling surface side of the seat portion (30) is concave in a cone shape has been shown, but, for example, the ceiling surface of the seat portion (30) may be made flat.

As described above, the fluid pressure device (10) operates so that the suction port (76x) of the pump (70) approaches the bottom of the container (20) in conjunction with a decrease in the remaining amount of liquid, and a storage space (35) is provided on an extension of the relative movement direction of the container (20) and the suction port (76x) with respect to the suction port (76x).

As in the fluid pressure transfer device (10) of the present embodiment, when the pocket (100) is set in the container (20) with the fluid non-receiving portion (104) facing the bottom side of the container (20) and a pressure force is applied to the pocket (100) by a plate (50) or the like, the fluid tends to gather in the fluid non-receiving portion (104). In the present embodiment, since the storage space portion (35) is provided on the extension line of the suction port (76x), the fluid that tends to gather toward the fluid non-receiving portion (104) can be smoothly sucked and pressured. Therefore, according to the fluid pressure transfer device (10) described above, the fluid can be pumped and pressured from the pocket (100) until the remaining amount is sufficiently reduced.

In addition, in this embodiment, as an example of a configuration in which the container (20) and the suction port (76x) move relative to each other so that the suction port (76x) of the pump (70) approaches the bottom of the container (20) in conjunction with a decrease in the remaining amount of liquid, an example in which the container (20) remains at a predetermined position while the pump (70) is moved in the axial direction by the lifting device (90) has been shown, but the present invention is not limited to this. For example, the pump (70) may be fixed at a predetermined position while the container (20) is configured to be able to approach and move away from the pump (70), or both the container (20) and the pump (70) may be moved relative to each other so as to approach in conjunction with a decrease in the remaining amount of liquid.

In addition, as described above, the fluid pressure sending device (10) has a peripheral space (38) between the outer surface (34a) of the sheet portion (30) and the inner surface (20a) of the container (20), and the peripheral space (38) extends in the axial direction of the container (20) and is open toward the storage space (35). Therefore, in the fluid pressure sending device (10), a void portion formed in the pocket (100) due to suction of the fluid can be relieved toward the peripheral space (38). In addition, in the fluid pressure sending device (10) of the present embodiment, a scraper (60) is provided, and by means of a curved portion (64) provided in the peripheral portion, an effect of pressing the void portion formed in the pocket (100) due to suction of the fluid into the peripheral space (38) can be expected. Therefore, in the fluid pressure transfer device (10), the possibility of hindering the suction of the fluid due to the presence of a void portion formed in the pocket (100) accompanying the suction of the fluid can be reduced. Accordingly, with the fluid pressure transfer device (10), the decrease in the suction efficiency of the fluid accompanying the presence of a void portion formed in the pocket (100), or the increase in the residual amount of the fluid that is not completely sucked, can be suppressed to a minimum.

In addition, in this embodiment, an example is shown in which a peripheral space (38) is formed between the outer surface (34a) of the sheet portion (30) and the inner surface (20a) of the container (20), but the fluid pressure device (10) may not have a peripheral space (38) formed therein. In addition, in this embodiment, an example is shown in which a scraper (60) having a bent portion (64) is used in order to expect the effect of pressing the void portion of the pocket (100) into the peripheral space (38), but the present invention is not limited to this. Specifically, the fluid pressure device (10) may be configured to use a scraper (60) that does not have a scraper (60), or, for example, does not have a bent portion (64), so that the effect of pressing the void portion of the pocket (100) into the peripheral space (38) is low or the pressing effect cannot be expected, or may be configured to have a configuration that can be expected to have the effect of pressing the void portion of the pocket (100) into the peripheral space (38) instead of or in addition to the bent portion (64).

As described above, the fluid pressure transfer device (10) can be configured to mount the adapter (36) on the fluid non-receiving portion (104) in a bundled state, and insert the adapter (36) while accommodating the fluid receiving portion (102) in the storage space (35). Therefore, in the fluid pressure transfer device (10), the fluid non-receiving portion (104) can be accommodated in the storage space (35) with good positioning precision. Therefore, in the fluid pressure transfer device (10), the fluid non-receiving portion (104) can be prevented from being obstructed when sucking the fluid, and the pumping residual amount of the fluid in the bag (100) can be minimized. In addition, although the present embodiment shows an example in which an adapter (36) is provided, the fluid pressure device (10) may be configured to not have an adapter (36), or instead of or in addition to an adapter (36), to have a configuration for accommodating the fluid non-receiving portion (104) in the receiving space portion (35) with good positioning precision.

As described above, the bag (100) exemplified in this embodiment is in a state where the fluid non-receiving portion (104) is tied and fixed in a rod shape. The fluid pressure sending device (10) can pump and send the fluid from the bag (100) until the remaining amount is sufficiently small, even if the fluid is contained in the bag (100) provided in this state. In addition, although this embodiment has shown an example where the bag (100) is provided in a state where the fluid non-receiving portion (104) is in a rod shape, the bag (100) may be, for example, a bag in which the fluid non-receiving portions (104) are tied in a bundle shape and fixed using a member such as a clip, rubber, or string, or a bag in which the fluid non-receiving portions (104) are tied in a bundle.

The present invention is not limited to the embodiments or modified examples described above, and there may be other embodiments from the teachings and spirit thereof without departing from the scope of the patent claims. The components of the embodiments described above may be arbitrarily selected and combined to form a configuration. In addition, any component of the embodiments and any component described in the means for solving the invention or any component embodying any component described in the means for solving the invention may be arbitrarily combined to form a configuration. Regarding these, there is an intention to acquire rights in the amendment or divisional application of the present application, etc.

The fluid pressure transfer device of the present invention can be suitably used in all applications of sucking and pressure-transferring a fluid from a bag having a fluid receiving portion and a fluid non-receiving portion.
