Hereinafter, the present invention will be described in detail through embodiments, but the following embodiments do not limit the invention according to the claims, and all combinations of features described in the embodiments It is not essential to the solution of the invention.

FIG. 1 is a cross-sectional view showing an outline of a pump 1 according to an embodiment. As shown in the figure, the pump 1 is composed of a plurality of mutually connectable pump units 1a to 1f. Note that the number of pump units can be changed as appropriate according to the length of the transport route. The configurations of the pump units 1a to 1f will be described below, but since each pump unit has the same configuration, the pump unit 1a will be described as an example.

As shown in FIG. 2, the pump unit 1a includes a cylindrical outer cylinder 10, a cylindrical inner cylinder 20 provided on the inner peripheral side of the outer cylinder 10, and the outer cylinder 10 and the inner cylinder 20. One end side flange 30 and the other end side flange 32 are respectively provided on one end side and the other end side in the axial direction. The axial direction means a direction along the cylinder axes O1 and O2 of the cylindrical outer cylinder 10 or the inner cylinder 20 .

The outer cylinder 10 is formed in a cylindrical shape with both ends opened, and both ends thereof are fixed by fixing rings 34a; As shown in FIG. 2(b), the outer cylinder 10 has rubber layers 12a; 12b made of, for example, low-ammonia natural latex rubber, and fiber layers 14 interposed between the rubber layers 12a; 12b. Become. The fiber layer 14 is composed of highly elastic fibers 14a made of a plurality of carbon fibers, glass fibers, aramid fibers, or the like laminated along the axial direction (radial direction). As shown in the figure, the extending direction of the high modulus fibers 14a is parallel to the axial direction of the outer cylinder 10. When the outer cylinder 10 is about to expand due to the introduction of air into the chamber 50, which will be described later, Extension (expansion) toward the center is restricted, and only expansion in the axial direction is permitted.

Inner cylinder 20 is cylindrical and made of a rubber member such as natural latex rubber or silicone rubber. Both ends of the inner cylinder 20 are fixed by a fixing ring 34 fitted in a concave portion 30a formed in the outer end surface of the one end side flange 30 and a concave portion 32a formed in the outer end surface of the other end side flange 32, respectively. . In addition, as shown in FIG. 2(c), a plurality of restraining bodies 15 extending along the axial direction of the inner cylinder 20 are inserted into the inner cylinder 20. As shown in FIG. As the restraining body 15, for example, a bundle of a plurality of fine carbon roving fibers having high strength is suitable. The extension direction of the restraining body 15 is parallel to the axial direction of the inner cylinder 20, and when the inner cylinder 20 tries to expand due to the introduction of air into the chamber 50, which will be described later, the extension (expansion) in the axial direction will occur. As a result of the restriction, only axial expansion is allowed. Further, in this example, four restraining bodies 15 are evenly inserted along the circumferential direction of the inner cylinder 20, but the number is not limited to this.

As shown in FIG. 2(a), when the openings at both ends of the outer cylinder 10 and the inner cylinder 20 are firmly fixed by the one end flange 30 and the other end flange 32, respectively, the outer cylinder is placed in the pump unit 1a. 10, a chamber 50 as a pressure supply chamber partitioned by the inner cylinder 20, the one end flange 30 and the other end flange 32 is formed. The chamber 50 is a space that extends along the axial direction around the cylinder axis O2 of the inner cylinder 20 . Fluid such as air is supplied into the chamber 50 from a pressure supply/discharge device (not shown).

As shown in FIG. 2(c), the one end flange 30 and the other end flange 32 each have a plurality of air tube insertion holes 36a to 36f and an air tube insertion hole 38b that are evenly arranged along the circumferential direction. ~38f is formed. The air tube insertion holes 36a to 36d and the air tube insertion holes 38b to 38f axially penetrate the one end flange 30 and the other end flange 32, respectively, and communicate the inside and outside of the chamber 50. As shown in FIG.

As shown in FIG. 2(a), an air tube 40a is inserted into the air tube insertion hole 36a of the one end flange 30 and terminates in the air tube insertion hole 36a. The air tube 40a is connected to a pressure supply/discharge device (not shown), and fluid such as air delivered from the pressure supply/discharge device is sent into the chamber 50 via the air tube 40a.

In addition, air tubes 40b to 40f are inserted into the air tube insertion holes 36b to 36f of the flange 30 on the one end side for supplying pressure to a plurality of other pump units connected to the other end. . The air tubes 40b to 40f pass through the chamber 50 and extend through air tube insertion holes 38b to 38f of the other end flange 32 formed at positions corresponding to the air tube insertion holes 36b to 36f, respectively. and individually supply pressure to other pump units connected to the other end. In the illustrated example, since a total of six air tube insertion holes 36a-36f are formed in the one end side flange 30, up to six pump units 1a-1f can be connected along the axial direction. Thus, the chamber 50 is formed as a sealed space by inserting a plurality of air tubes 40a to 40f, and when air is supplied into the chamber 50 through the air tubes 40a, the outer cylinder 10 and the inner cylinder 20 will expand.

As shown in FIGS. 2(a) and 2(c), the inner peripheral surface 22 of the inner cylinder 20 is in direct contact with the object to be conveyed or the object to be kneaded (hereinafter simply referred to as the "object"). , a separation sheet 60 extending along the axial direction over the entire circumferential direction is interposed. As also shown in FIG. 1, the separation sheet 60 is a screen material such as vinyl chloride or a rubber sheet having a resilience that extends continuously along the axial direction of the plurality of pump units 1a to 1f. It is arranged in a state facing the inner peripheral surface 22 of the inner cylinder 20 of 1a to 1f. It should be noted that the separation sheet 60 does not necessarily need to be brought into close contact with the inner peripheral surface 22, and a gap may exist between the separation sheet 60 and the inner peripheral surface 22. FIG.

As shown in FIG. 2A, one open end 60a of the separation sheet 60 is fixed by a recess 30b formed in the outer end surface of the one end flange 30 and a fixing ring 35 fitted into the recess 30b. , an object can be put into the inner cylinder 20 from the open end 60a. The other open end of the separation sheet 60 is a fixing ring that is fitted into a recess (not shown) formed in the outer end face of the other end flange 32 of the rearmost pump unit (pump unit 1f in the illustrated example). fixed by Objects in the inner cylinder 20 can be discharged from the open end.

As described above, the separation sheet 60 extends continuously along the axial direction of the plurality of connected pump units 1a to 1f so as to cover the inner peripheral surface 22 of the inner cylinder 20 of each of the pump units 1a to 1f. to prevent an object put into the inner cylinder 20 from directly contacting the inner peripheral surface 22 . Therefore, the object to be conveyed does not adhere or remain on the inner peripheral surface 22 . The separation sheet 60 can be easily removed from the inner cylinder 20 by removing the fixing ring 35 of the one end flange 30 and the fixing ring (not shown) of the other end flange 32 .
Therefore, for example, assuming that the object B is transported after the object A is transported, by removing the separation sheet 60 after the object A is transported, the object can be transported immediately without cleaning the inner peripheral surface 22 . B can be transported. Further, since the object A does not remain on the inner peripheral surface 22, it is possible to prevent the object A from being mixed with the object B. Therefore, even if there is a specific food ingredient that should be avoided from the viewpoint of allergies or beliefs, it is possible to prevent the ingredient from mixing with other food ingredients, and the pump can also be used as a food material pump. In addition to foods, the present invention can be applied to any object, such as medicines and industrial products, as long as it involves transportation and mixing.

A specific operation of the pump unit 1a having the above configuration will be described below with reference to FIGS. 2 and 3. FIG. When a predetermined pressure such as air is applied in the chamber 50, the outer cylinder 10 expands outward in the axial direction and contracts in the axial direction. That is, since the fiber layer 14 is formed in the outer cylinder 10 along the axial direction, the elongation in the axial direction is restricted. As a result, the expansion direction of the outer cylinder 10 is limited to the outer side in the axial direction, and the length in the axial direction shrinks as the outer cylinder 10 expands in the outer side in the axial direction.

Further, when a predetermined pressure such as air is applied in the chamber 50, the inner cylinder 20 expands inward in the axial direction and contracts in the axial direction. In the same manner as described above, since the restraining body 15 extending along the axial direction is inserted in the inner cylinder 20, extension in the axial direction is restricted. As a result, the direction of expansion of the inner cylinder 20 is limited to the inner side in the axial direction, and the length in the axial direction shrinks as the inner cylinder 20 expands inward in the axial direction. As shown in FIG. 3(b), since the restraining bodies 15 are inserted into the inner cylinder 20 at equal intervals along the circumferential direction, the inner cylinder 20 is divided into a plurality of parts with each restraining body 15 as a starting point. expansion regions 20a to 20d.

By repeatedly supplying and discharging a predetermined pressure into the chamber 50 and causing the inner cylinder 20 to repeatedly expand and contract, the object existing in the inner cylinder 20 is pushed out by increasing or decreasing the volume inside the inner cylinder 20. It will be conveyed to the adjacent pump unit side. At this time, the separation sheet 60 corresponding to the inner peripheral surface 22 also comes into close contact with the inner peripheral surface 22 in response to the change in expansion of the inner cylinder 20, directly contacts the object, and pushes out the object. In addition, since each of the pump units 1a to 1f in this example is contracted in the axial direction, the object in the inner cylinder 20 is pushed out toward the adjacent pump unit, thereby conveying the object more efficiently. can do. Here, the object that can be conveyed or kneaded may be any object as long as it has a certain fluidity that can be moved according to the volume change of the inner cylinder 20. , liquids, or mixtures or aggregates thereof can be easily conveyed and kneaded.

Next, an example in which an object A is transported from one side to the other by the pump 1 having the above configuration will be described with reference to FIGS. 1 and 4. FIG. As shown in FIG. 1, each of the pump units 1a to 1f has a flange 30 on one end and a flange 32 on the other end that are connected to each other via fixing means (not shown). A conveying path having a predetermined length is formed by connecting the internal flow path L formed by the tube 20 . A pressure supply/discharge means 120 is connected to the pump 1 .

The pressure supply/discharge means 120 includes an air compressor C that delivers compressed air, a plurality of proportional solenoid valve groups V (V1 to V6) connected to the air compressor C via air tubes, and the proportional solenoid valve group V and a plurality of 3-port solenoid valves P (P1-P6) connected via air tubes, proportional solenoid valve group V and 3-port solenoid valve group P are individually controlled, and the chambers of each pump unit 1a-1f and a control device S that controls the supply and exhaust of air into and out of 50 .

As shown in the figure, one port of each of the 3-port solenoid valves P1 to P6 is connected to the chamber 50 of each pump unit 1a to 1f through air tubes 40a to 40f. An air supply system leading to the chambers 50 of 1a-1f is established. In this embodiment, since the pump 1 is configured by six pump units 1a to 1f, it is configured to have six supply systems, but it goes without saying that the number of systems changes according to the number of pump units. .

The control device S is a computer equipped with hardware such as a CPU as computing means and ROM and RAM as storage means. By controlling, each pump unit 1a to 1f is expanded individually. For example, to operate the pump unit 1a, the proportional solenoid valve V1 is opened and one port side of the 3-port solenoid valve P1 is opened. It is supplied into the chamber 50 of the pump unit 1A, and only the pump unit 1a expands. The pressure of the air supplied into the chamber 50 can be freely adjusted according to the current value to the proportional solenoid valve V1, and the inner cylinder 20 can be freely changed from the fully open state to the fully closed state. . The same applies to the pump units 1b to 1f. By individually controlling the proportional solenoid valves V2 to V6 and the 3-port solenoid valves P2 to P6 included in the corresponding supply systems, the pump units 1b to 1f can be inflated individually.

Next, an exhaust system for air supplied to each of the pump units 1a to 1f will be described. As shown in the figure, the other ports of the 3-port solenoid valves P1-P6 are connected to an air regulator R via an air tube. The air regulator R is connected to an air pump Q via an air tank T. As shown in FIG. For example, in order to discharge the air supplied to the pump unit 1a, one port and the other port of the 3-port solenoid valve P1 may be opened while the air tank T is being driven. The air in the chamber 50 is forcibly exhausted by the air pump Q and stored in the air tank T. The pressure inside the chamber 50 after exhaustion can be adjusted by setting the regulator R. The same applies to the pump units 1a to 1f. By individually controlling the proportional solenoid valves V2 to V6 and the 3-port solenoid valves P2 to P6 included in the corresponding exhaust system, the pump unit after the expansion operation 1b to 1f can be individually restored to their natural lengths (before expansion).
The air supplied into the chamber 50 may be released to the atmosphere by the restoring force of the outer cylinder 10 and the inner cylinder 20 without separately providing the exhaust system. On the other hand, if an exhaust system is provided to forcibly exhaust air, the return to the natural length of the outer cylinder 10 and the inner cylinder 20 becomes faster when the viscosity of the object is high. It becomes possible to improve the transportation efficiency of the object passing through L.

Next, referring to FIG. 4, the basic operation of conveying the object A from one side to the other side in the axial direction by the pump 1 composed of the pump units 1a to 1f will be described. As shown in FIG. 4, the pump 1 is arranged, for example, in a part of the pipeline J, and conveys the object A flowing in from the upstream side of the pipeline J to the pipeline J on the downstream side.

After the object A has flowed into the pump unit 1a as shown in FIG. 4(a), the pump unit 1a is closed (inflated) as shown in FIG. to the pump unit 1b side. Next, as shown in FIG. 4(c), the pump unit 1b is closed, and the upstream pump unit 1a is opened after a time lag. By this operation, the object A in the pump unit 1b is conveyed to the downstream side of the pump unit 1c, and a new object A flows into the pump unit 1a. Hereinafter, as shown in FIG. 4(d), by sequentially repeating the closing operation of the pump unit located on the downstream side and the opening operation of the pump unit located on the upstream side with a time difference from the closing operation, the target Object A is continuously conveyed downstream. After the transfer of the object A is completed, the separation sheet 60 is removed from the pump 1 and a new separation sheet 60 is attached, thereby preventing contamination of the inner peripheral surface 22 and mixing of different objects. can be done.

FIG. 5( a ) is a schematic diagram showing a separation sheet 60 suitable for kneading objects having different physical properties with the pump 1 . As shown in the figure, the separation sheet 60 according to this example is in the form of a bag which is open at one end and closed at the other end. The open end 60a of the separation sheet 60 having such a shape is fixed to the one end side flange 30, and the closed end 60c is inserted up to the rearmost pump unit 1f. Further, the other end side flange 32 of the rearmost pump unit 1f is formed with a lid portion 32c that closes the other end side of the inner cylinder 20, so that the object can stay inside the pump unit 1f. be.

As shown in FIG. 5(b), after the separation sheet 60 is arranged, the object A is put into the pump unit 1a, and the opening of the one end flange 30 is closed with a cover (not shown). By repeatedly operating the pump units 1a to 1f as described above, the object A is kneaded and transported toward the downstream pump unit 1f. Depending on the required kneading time, the object A that has reached the pump unit 1f is transported again toward the pump unit 1a by operating in the reverse order of the operation of the pump units 1a to 1f described above. It is also possible to knead while mixing. It is also possible to use only some of the pump units (for example, 1a to 1c) as the pump units to be operated, and knead while reciprocating between the pump units 1a to 1c. In this case, the downstream pump unit 1d should be closed. Further, the lid of the one end flange 30 may be provided with an injection hole into which a chemical liquid such as a curing agent or powder can be injected.

As shown in FIG. 5(c), after the object A is kneaded, the object B is put into the pump unit 1a, and while the object B is kneaded by the operation of the pump units 1a to 1f, the object A is kneaded. It is conveyed toward the remaining pump unit 1f.

After the object B reaches the pump unit 1f after a predetermined kneading time, in order to mix the object A and the object B uniformly, for example, the pump unit 1d is closed, and The pump units 1e; 1f are operated repeatedly to produce a mixture AB over a predetermined kneading time. After that, by removing the separation sheet 60, the mixture AB integrally stored in the separation sheet 60 can be obtained. In this example, a single separation sheet 60 is arranged with respect to the pump 1, but a plurality of separation sheets 60 may be arranged along the axis, and an arbitrary object may be put into each separation sheet 60. By kneading in the mixed state, it is also possible to produce a plurality of mixtures of the same formulation (mixture AB) or different formulations (mixture AB and mixture AC) at once.

FIG. 6(a) is a schematic diagram showing a modification of the separation sheet 60 suitable for kneading objects. The separation sheet 60 shown in FIG. Each of the storage chambers 62a to 62c is partitioned by an outer peripheral portion 64 facing the inner peripheral surface 22 and a plurality of partitions 66a to 66c partitioning the inside of the outer peripheral portion 64. As shown in FIG. Objects A to C corresponding to preset compounding ratios are quantitatively accommodated in the storage chambers 62a to 62c. In addition, the plurality of partitions 66b; 66c are formed more fragile than the outer peripheral portion 64 and the partition 66a, and when a predetermined pressure or higher is applied to the storage chambers 62a to 62c, the objects inside may be damaged. It becomes possible to flow into the containment room. The fragility of the partitioning portions 66b; 66c can be realized by, for example, forming them with a material having lower strength than the outer peripheral portion 64 and the partitioning portion 66a, making them thinner, forming perforations, and the like.

As shown in FIG. 6(b), the aforementioned separation sheet 60 in which the objects A to C are enclosed in advance is inserted into the pump 1, and the opening of the one end flange 30 is closed with a cover (not shown). Then, with the pump unit 1a closed, for example, the pump units 1b to 1d corresponding to the positions of the object A and the object B are repeatedly operated for a predetermined kneading time, and then a higher pressure is applied to the pump units 1b to 1d. The voltage is applied to break the partition 66b that separates the storage chambers 62a; 62b. After that, by continuously operating the pump units 1a; 1b, the object A and the object B are kneaded together in the storage chambers 62a; 62b to form a mixture AB.

Next, as shown in FIG. 6(c), in addition to the pump units 1b to 1d, the pump units 1e; 1f corresponding to the position of the object B are repeatedly operated for a predetermined kneading time. to break the partition 66c that separates the storage chambers 62a; 62b and the storage chamber 62c. After that, by continuously operating the pump units 1b to 1f, the object A, the object B, and the object C are kneaded together in the storage chambers 62a; 62b; 62c to produce a mixture ABC. be done. Finally, by removing the separation sheet 60 from the pump 1, it is possible to obtain the mixture ABC which is uniformly mixed in the separation sheet 60 and integrally accommodated. The operation order of each pump unit can be appropriately set according to the mixing order of the objects, and the number of storage chambers can also be appropriately set according to the number of objects to be stored.

In the above modification, the separation sheet 60 pre-filled with the objects A to C is inserted into the pump 1, and the partitions 66b; 66c are broken to obtain the mixture ABC. C may be individually housed in a fragile bag that is ruptured by pressure, and the mixture ABC may be produced in the pump 1 in which the separation sheet 60 shown in FIG. 5 is arranged.

Although the present invention has been described above using the embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments. It is also obvious to those skilled in the art that various modifications and improvements can be made to the above embodiments. It is clear from the scope of the claims that forms with such modifications or improvements can also be included in the technical scope of the present invention.

For example, in the present embodiment, the pump units 1a to 1f are configured to be expanded in the axial direction, but the configuration is not limited to this. The pump may be configured by a pump unit that does not involve an extension operation by omitting the restraining body 15 disposed in the outer cylinder 10 and forming the outer cylinder 10 from resin or metal having a high rigidity.

Further, for example, the separation sheet 60 may be provided with a check valve, or may be provided with an opening into which a tube or the like can be inserted, so that gas generated and remaining inside can be discharged to the outside. Further, the frictional force generated between the separation sheet 60 and the object may be adjusted by applying embossing or the like to the separation sheet 60 . Alternatively, a material that changes color depending on pressure or temperature may be used as the separation sheet 60 to visualize the kneading state. For example, if the color changes as a whole, it can be determined that the material has been sufficiently heated and kneaded. Moreover, when the object is a specific fuel or the like, it is possible to take out the separation sheet 60 and burn it as it is, or to attach it to a rocket motor or the like as it is.
