Description

  The present invention is a technique applied to, for example, a coating apparatus or a filling apparatus.

  The coating material layer is provided on rock, ground, or a structure (its member). The purpose of providing the coating material layer is various. For example, the purpose is to provide strength improvement, durability improvement, fire resistance improvement, fire protection improvement, sound absorption improvement, and / or heat insulation. Examples of the coating material include fire-resistant coating materials such as rock wool, sprayed rock wool made of cement and water. For example, concrete or mortar. Then, the coating material is provided (covered) at a desired location by a spraying method or the like.

  The filler is filled in the formwork, the ground, the gap, or the like. There are various fillers. For example, a ground injection material. Alternatively, it is concrete, mortar, grout material or the like.

  Part of the material constituting the coating material (or filler) is liquefied (fluidized) (or using a liquid), and the coating is discharged (or discharged) from the discharge port at the tip of the pressure feeding path. The additive (the liquefaction) that constitutes the covering material (or the filler) in the vicinity of the discharge port is added to the simple substance (or mixture) of the main material (the main material) that constitutes the material (or the filler) (Fluidized) material (or liquid)) is added (mixed). This mixture is the coating material (or filler), which is provided at a desired location and becomes the coating material layer (filler layer).

  When the additive is liquid or liquid (liquid such as emulsion or slurry), a liquid additive outlet (including a spray nozzle (tip)) is provided on the outer periphery (or / and inside) of the main material discharge port. The main material that has been pressure-fed and discharged from the discharge port at the tip of the pressure-feeding path (or that has been pressure-fed near the tip of the pressure-feeding path) is discharged in the form of a mist from the liquid additive discharge port. It has been proposed to join (mix) the added liquid additives. Thus, for example, spraying is performed on the ground surface (see Patent Documents 1 and 2).

  A flow meter is provided in a main material pressure feeding path, and an electric signal from the flow meter is sent to a sub material flow rate adjusting means in the liquid additive material (sub material) pressure feeding path and the sub material is adjusted based on the flow rate of the main material. A device having a means for adjusting the flow rate of the material is used, and a mixing valve between the main material and the auxiliary material is adjusted by adjusting a flow rate of the auxiliary material by an adjustment valve in a pressure feeding path of the auxiliary material. A technique has been proposed in which the value is adjusted to a predetermined value (see Patent Document 3).

Japanese Utility Model Publication No. 02-031170 Japanese Utility Model Publication No. 08-006507 JP 2003-035095 A

  For a variety of reasons (eg, to check the thickness of the coated coating, to change (move) the coating location, or to adjust the orientation (and / or position) of the material outlet) The construction may be stopped once and then resumed. This suspension / resumption may occur many times in one day in some cases. The stop / restart is performed by opening / closing a valve arranged near the front end of the pressure feeding path for the auxiliary material (liquid additive). That is, the stop / restart is performed by stopping or restarting the addition of the auxiliary material (liquid additive). The valve may be used to adjust the amount of the auxiliary material (liquid additive) added (see Patent Document 2). However, when the valve is closed once to stop the addition of the auxiliary material (liquid additive), the addition amount of the auxiliary material (liquid additive) is readjusted when the construction is resumed, that is, when the valve is opened. There must be. Otherwise, the mixing ratio of the main material and the auxiliary material (liquid additive) of the coating material changes before and after the resumption of the construction, and the properties of the coating material change.

  The mixing ratio of the main material and the auxiliary material (liquid additive) constituting the coating material is usually determined. For example, for sprayed rock wool, which is a fire-resistant coating material, the ratio of cement, rock wool and water is determined (Minister of Land, Infrastructure and Transport certified). If the ratio deviates from the Ministry of Land, Infrastructure, Transport and Tourism's certification, it will not be a fire-resistant coating material certified by the Ministry of Land, Infrastructure, Transport and Tourism.

  By discharging the auxiliary material (liquid additive) from the liquid additive outlet as finely as possible, the mixing of the main material and the auxiliary material (liquid additive) constituting the coating material is improved. For this reason, a somewhat high pressure is applied to the pressure feeding of the auxiliary material (liquid additive). For this reason, when the valve is closed, a high liquid pressure is applied to the pumping path of the auxiliary material (liquid additive). For this reason, the following problem (the hose in the path ruptures, the connection part such as a joint is disconnected, and leakage occurs) increases.

  The invention of Patent Document 3 is a very complicated mechanism. Expensive. When the valve in the secondary material (liquid additive) feed path is closed (the liquid additive is stopped), the following problem (the hose in the path ruptures. The connection part such as a joint is disconnected. Occurs).

  The present invention is to solve the above problem. For example, it is an object of the present invention to provide a technique capable of keeping the addition amount of the liquid additive constant even if the addition of the liquid additive is stopped or restarted during the construction. Alternatively, even if the addition of the liquid additive is stopped during the construction, the liquid pressure in the liquid additive pumping path may damage members in the path, a connection portion of the path may be disconnected, or leakage of the liquid additive may occur. It is to provide technologies that are unlikely to occur.

  A first invention is an apparatus. This is a device used to join multiple materials. The plurality of materials are, for example, a main material and an auxiliary material. The main material can be appropriately selected according to the purpose. The auxiliary material can be appropriately selected depending on the purpose. The device is a device applied (adopted) to, for example, a coating device or a filling device. For example, it is a liquid additive supply device that forms (produces: prepares) a coating material by combining and mixing a plurality of types of materials (for example, a main material and an auxiliary material (liquid material (for example, liquid additive))). Alternatively, it is a liquid additive supply apparatus in which a plurality of types of materials (for example, a main material and an auxiliary material (a liquid material (for example, a liquid additive))) are combined and mixed to form a filler (manufacture: preparation). The apparatus includes a pump for supplying (transporting: pumping) a liquid material (for example, a liquid additive) that is at least one of the plurality of materials. The device comprises a leak device. The device comprises a flow meter. The device comprises a flow regulator. The device comprises a flow indicator. The apparatus includes a connection port (a connection port to which a pressure-feeding hose for pressure-feeding the liquid material is connected). One end of the pressure feeding hose is connected to the connection port. The other end of the pressure feeding hose is connected to, for example, a nozzle. The pressure pump has an inlet and an outlet. The leak device has an inlet, an outlet, and a leak outlet. The discharge port of the pressure pump and the inlet of the leak device are connected directly or indirectly. The direct connection means that the outlet and the inlet are connected without passing through another member (for example, a tube or a tube). Indirect connection means that the outlet and the inlet are connected via another member (for example, a pipe or a tube). The outlet and the connection port of the leak device are connected directly or indirectly. Direct or indirect has the meaning according to the above description. It is preferable that the outlet of the leak device is directly or indirectly connected to at least one of the flow control device and the connection port. For example, the outlet of the leak device and the flow control device are connected directly or indirectly. Alternatively, the outlet of the leak device and the connection port are connected directly or indirectly. Direct or indirect has the meaning according to the above description. The flow control device and the connection port are connected directly or indirectly. The flow rate adjusting device is provided, for example, at some point in a path from an outlet of the leak device to the connection port. The flow meter is provided on a path from an outlet of the leak device to the connection port. The flow rate display device is connected to the flow meter.

  The device is preferably provided with a pressure gauge in a path from an outlet of the leak device to the connection port. If the pressure gauge is provided, the pressure in the passage can be checked. Therefore, before the members (parts) in the pumping passage are damaged, dislodged or leaked, the pressure is adjusted or the pump is stopped while checking the pressure. This is convenient. Preferably, the flow rate display device and the flow rate display device are located at a position where the flow rate control device can be adjusted while checking information (numerical values) displayed on the flow rate display device (five senses of a person, for example, checking with eyes). A flow control device is arranged. By doing so, the flow rate adjustment work becomes easy. In the apparatus, preferably, the leak device includes a leak pressure adjusting unit. By doing so, the leak pressure can be adjusted, which is convenient.

  The second invention is a method. The method includes a step in which a liquid material is quantitatively pumped and ejected from a nozzle connected to the other end of a liquid material pumping hose connected to the apparatus. The method includes a step of merging the injected liquid material with a main material that has been quantitatively fed.

  The covering material (or filler) is composed of a main material and an auxiliary material. The covering material (or filler) is formed by merging and mixing the main material and the sub-material. What the main material and the auxiliary material are is not particularly limited as long as they are understood in the art. The auxiliary material is generally a liquid material. The liquid material includes not only a liquid but also a liquid material. For example, a slurry is also included. In the art, there are materials known as so-called liquid additives. Combinations of the main material and the auxiliary material are exemplified below. The main material is mortar or concrete, and the auxiliary material is a liquid admixture (eg, a liquid quick-setting agent, a slurry-type quick-setting agent, a resin emulsion, etc.). The main material is a premix mortar, and the auxiliary material is an admixture made of water, an aqueous solution, an emulsion, or a slurry containing water as a dispersion medium, or a mixture thereof. The main material is dry concrete, and the auxiliary material is water, an aqueous solution, an emulsion, or an admixture made of a slurry using water as a dispersion medium, or a mixture thereof. The main material is fiber such as rock wool (including slag wool), glass wool, cellulose fiber, synthetic resin fiber and the like, and the auxiliary material is cement slurry. The main material is a fiber such as rock wool (including slag wool), and the auxiliary material is a resin emulsion or a liquid polymer. The main material is a dry mixture of fibers such as rock wool (including slag wool) and a powdery binder such as cement, and the auxiliary material is water, an aqueous solution, an emulsion, or an admixture made of a slurry containing water as a dispersion medium or a mixture thereof. And mixtures.

  The pump (for example, a liquid additive pump) has an inlet and an outlet. Any material can be used as long as it can pump the liquid material (for example, liquid additive). For example, reciprocating pumps (for example, diaphragm pumps, piston pumps, plunger pumps, etc.), rotary pumps (for example, screw pumps, gear pumps, etc.), centrifugal pumps (for example, turbine pumps, volute pumps, etc.), squeeze pumps Pumps and the like. The intake port communicates with a liquid material (for example, liquid additive) storage tank, and a liquid material in the liquid material (for example, liquid additive) storage tank is sucked and taken in from the intake port. The liquid is discharged from the discharge port and fed to the inlet of the leak device.

  The leak device has an inlet, an outlet, and a leak outlet. Preferably, a safety valve is also provided. The safety valve includes a valve body, a valve seat, a valve stem, a spring, and a case. More preferably, a pressure adjusting valve having a pressure adjusting screw is provided. The leak device is configured such that, while the pump is operating, a valve in a pumping path of a liquid material (for example, a liquid additive) is closed, and when the liquid pressure of the liquid material increases, the liquid material pushes up the valve body. Thus, the inlet and the leak outlet communicate with each other, and the liquid material is discharged from the leak outlet. The liquid pressure does not become higher than the set pressure of the safety valve, and it is difficult for the members in the liquid material pumping path to be damaged, for the connection part of the path to be disconnected, and for the liquid material to leak. If the leak device is provided with a leak pressure adjusting means, the hydraulic pressure can be initially reduced and gradually increased. Therefore, it is preferable because breakage, detachment, liquid leakage, and the like hardly occur. For example, a pressure adjusting screw, a pressure adjusting valve provided with the screw, and an equivalent thereof are leak pressure adjusting means. The safety valve is a pressure regulating valve, is a leak device provided with the leak pressure regulating means, and a pressure gauge is arranged in a path from an outlet of the leak device to the connection port (liquid additive material pressure feeding hose connection port). With this configuration, the set pressure of the safety valve (pressure regulating valve) can be adjusted while checking the liquid pressure of the liquid material. Therefore, it can be confirmed that the liquid material (liquid additive) does not exceed the pressure resistance value of the members in the pressure feeding path. As in the case of construction, when the valve in the liquid material (liquid additive) pumping path is open, the liquid material does not push up the valve body, and all the liquid material entering from the inlet of the leak device from the outlet. Is discharged.

  The flow meter may be of any type as long as it can measure the flow rate of a liquid material (liquid additive). A contact type flow meter or a non-contact type flow meter may be used.

  The flow rate adjusting device may be any device as long as the flow rate of the liquid material (liquid additive) can be adjusted. For example, there are a butterfly valve, a gate valve, a globe valve, a needle valve, a ball valve, and the like. In particular, a needle valve and a globe valve are preferable because the flow rate can be finely adjusted easily. A gear-type or handle-type (including a dial-type) valve is preferable to a lever-type valve because the flow rate can be finely adjusted. Inverters and transmission gears (gearboxes, transmissions) arranged and connected to control the operation of the liquid additive pump are also preferred examples of the flow control device.

  The flow rate display device may be any device as long as it can display the flow rate of the liquid material (liquid additive) measured by the flow meter. Decidal type flow rate display devices are preferable because the numerical value of the flow rate can be easily grasped.

  It is preferable to arrange the flow rate display device and the flow rate control device at a position where the flow rate control device can be adjusted while confirming information (for example, flow rate per short time) displayed on the flow rate display device, preferable. By doing so, the flow rate of the liquid material (liquid additive) can be adjusted by one person.

  Hereinafter, the present invention will be described specifically. The following examples are merely examples of the present invention.

  As can be seen from FIGS. 1, 2 and 3, one end of the suction hose 6 is inserted (provided) into the liquid additive storage container 8. The other end of the suction hose 6 is connected to the inlet 31 of the liquid additive pump 30. The outlet 32 of the liquid additive pump 30 and the inlet 21 of the leak device 20 are connected via a hose. The leak device 20 is provided at the next stage of the liquid additive pumping pump 30. One end of a leak discharge hose 24 is connected to a leak discharge port 23 of the leak device 20. The other end of the leak discharge hose 24 is inserted (provided) into the liquid additive storage container 8. The leak device 20 includes a pipe having an inlet 21 and an outlet 22, a case 29 communicating with the pipe via a valve seat 26, a valve body 25 in contact with and closing the valve seat 26, A spring 28 accommodated in a cylindrical spring accommodating portion, which is a part, together with an upper spring retainer 37 and a lower spring retainer 38; a valve stem 27 in contact with the lower spring retainer 38 and the valve body 25; It has a lid 35 screwed with a male screw formed in the portion, and a rod 36 in contact with the inside of the lid 35 and the upper spring receiver 37. The outlet 22 of the leak device 20 and the flow control device 17 are connected via a hose. The flow control device 17 is provided at the next stage of the leak device 20. The flow control device 17 and the flow meter 15 are connected via a hose. The flow meter 15 is provided at the next stage of the flow control device 17. The flow meter 15 may be provided before the flow rate adjusting device 17. A flow display device 16 is connected (provided) to the flow meter 15. The flow meter 15 and the pressure gauge 14 are connected via a hose. The pressure gauge 14 and the liquid additive pressure feeding hose connection port 7 are connected via a hose. The liquid additive material supply hose connection port 7 is connected (provided) to a liquid additive material supply hose 13. The distal end side of the liquid additive material supply hose 13 is connected (provided) to a valve 18 attached to the nozzle member 3 for ejecting the main material. The main-material jetting nozzle device 3 includes a pipe through which the main material passes, a ring-shaped liquid additive passage provided around the pipe, and the valve communicating with the ring-shaped liquid additive passage. 18 and a plurality of nozzle devices (nozzle chips, not shown) for jetting liquid additive. The liquid additive injection nozzle device and the valve 18 (not shown) are integrally attached to the main injection nozzle device 3. One end side of a main material pressure feeding hose 9 is connected to a pipe through which the main material of the main material ejection nozzle device 3 passes. The other end of the main material pressure feeding hose 9 is connected to a main material pressure fixed supply device 10. The blower 2 is attached to the main material pressure fixed supply device 10.

  The device configured as described above operates as follows. The main material 11 is supplied from the main material jetting nozzle device 3 via the main material quantitative supply device 10 at a rate of Xml / min by the main material pressure quantitative supply device 10 connected to the blower 2 (ejection: (Discharge). On the other hand, the operation of the liquid additive pump 30 causes the liquid additive 12 in the liquid additive storage container 8 to be sent out at a rate of Yml / min. The liquid additive 12 is supplied (spouted: discharged) from a liquid additive injection nozzle device (nozzle tip) via a liquid additive pumping hose 13. As a result, the main material 11 and the liquid additive material 12 merge to form a mixed liquid, which becomes a coating material (or a filler), and is sprayed (filled) at a predetermined location.

  Here, there is a case where it is desired to temporarily stop and restart the supply of the liquid additive. In such a case, the valve 18 attached to the main material jetting nozzle device 3 is closed without stopping the liquid additive pumping pump 30. Then, since the leak device 20 is provided on the front side of the valve 18, the liquid additive delivered from the liquid additive storage container 8 by the liquid additive pumping pump 30 removes the valve element 25 and the valve element 25. A gap is formed between the valve body 25 and the valve seat 26 by pressing the valve rod 27, the lower spring receiver 38, and the spring 28 through the valve rod, and a part of the liquid additive flows into the case 29 and leaks from the leak outlet 23. It is returned to the liquid additive storage container 8 via the discharge hose 24. That is, the liquid additive 12 in the liquid additive storage container 8 is circulated through the circulation path (the liquid additive storage container 8 → the suction hose 6 → the liquid additive pressure pump 30 → the leak device 20 → the leak discharge hose 24 → the liquid additive). The liquid is returned into the liquid additive storage container 8 by the storage container 8). Here, of course, there is no overload. Therefore, an accident does not occur in which the liquid additive 12 leaks from any connection site. There is no accident that the member is removed at any connection site. There is no accident that any part is damaged.

  In the above embodiment, the leak device 20 includes a pressure adjusting valve (leak pressure adjusting means) including a pressure adjusting screw. When the cover 35 is turned in the direction in which the screw is closed to the spring accommodating portion of the case 29, the spring 28 is further contracted, and the valve body 25 is strongly pressed by the valve seat 26 via the lower spring receiver 38 and the valve rod 27, and the liquid additive If the pressure does not become higher, a gap between the valve body 25 and the valve seat 26 cannot be formed. Conversely, when the cover 35 is turned in the direction in which the screw is loosened in the spring accommodating portion of the case 29, a gap is formed between the valve body 25 and the valve seat 26 even if the liquid pressure of the liquid additive is lower, and the leak discharge port 23 Part of the liquid additive is discharged. It is preferable to provide a guide (for example, a scale) on the lid 35 or the spring accommodating portion of the case 29 so that the pressure can be easily adjusted.

  When the supply of the liquid additive is resumed, simply opening the ball valve 18 attached to the nozzle member 3 for ejecting the main material causes the liquid pressure of the liquid additive to drop, so that the gap between the valve body 25 and the valve seat 26 is reduced. As a result, the liquid additive does not flow into the case 29, so that the liquid additive is not discharged from the leak outlet 23. Further, the liquid additive at a flow rate (Yml / min) adjusted in advance by the flow rate adjusting device 17 is sent out, and supplied (spouted: discharged) from the liquid additive ejecting nozzle device (nozzle tip, not shown). Then, it is mixed with the main material 11 at a predetermined ratio to form a mixed liquid, which becomes a coating material (or a filler), and is sprayed (filled) at a predetermined location.

  In the above embodiment, since the leak device 20 includes the pressure adjusting valve (leak pressure adjusting means) including the pressure adjusting screw, and the pressure gauge is provided in the path from the outlet of the leak device to the connection port, Adjustment of the pressure adjusting screw (that is, the degree of tightness of the lid 35 with respect to the spring accommodating portion of the case 29) creates a gap between the valve body 25 and the valve seat 26, and a part of the liquid additive material from the leak discharge port 23. Since the fluid pressure at the start of discharging can be confirmed, it is easy to reliably adjust the fluid pressure so as not to overload.
