Description

  The present invention relates to a sealing material filling apparatus for applying a sealing material made of a high-viscosity material to joints and joints of concrete in buildings or joints such as walls and tiles. The sealing material is a material that fills the joints and joints in order to obtain water tightness and air tightness, and is also called a caulking material, for example.

  Usually, a building sealing material used in a construction site is formed of a two-component base and a curing agent, and a color master is mixed. In general, this sealant was filled using a manual two-component suction gun. This two-component suction gun is of a cartridge type, and the sealing material in the cartridge inserted into the receiving member is pushed out by the piston to fill the joints and joints. However, the amount of the reeling material that fills joints and joints such as walls and concrete every day reaches a considerable amount, and the operation of pushing out the sealing material with the piston is manually operated each time. For this reason, the number of hand operations reaches a considerable number, which is a work accompanied by fatigue. Moreover, since it is a cartridge type, when the sealing material of one cartridge is used, a new cartridge is inserted into a receiving tool, which is a laborious work.

Therefore, conventionally, as shown in the sealing material filling apparatus of Patent Document 1, an apparatus for filling a sealing material without using a cartridge has been disclosed. According to this, the pot which stores a sealing material is arrange | positioned in a pumping machine, and the gun machine is attached to the front-end | tip of the pumping pipe connected from the pumping machine. Therefore, by feeding the sealing material with a pressure feeder, it becomes possible to continuously fill the high-viscosity sealing, and it is possible to perform continuous construction with less labor and less labor for replacing the cartridge.

  However, in order to continuously feed a high-viscosity sealing material, there is a problem that even if it is simply sent by a pressure feeder, the sealing material is hardened and cannot be fed every time. Since the sealing material continuous filling device of Patent Document 1 only sends the sealing material with a pressure feeder, there remains a problem with sending the sealing material without curing. Further, when working at a high place in the structure, it is necessary to easily carry the pressure feeder, and the sealing material continuous filling device of Patent Document 1 has a problem in this respect.

  The present invention solves the above-described problems, and provides a sealing material filling apparatus that can perform continuous filling, can be filled with a sealing material without labor, and can be easily carried. The purpose is to do.

Therefore, the sealing material filling apparatus according to the present invention is configured as follows. That is,

  In the present invention, the sealing material stored in the tank is rotated in one direction by the operation of the drive unit, whereby the suction port is rotated to stir the sealing material in the tank. On the other hand, the sealing material sucked from the suction port moves onto the spiral groove of the spiral shaft and is introduced into the spiral groove. And it is sent along a spiral groove with rotation of a spiral axis. At this time, an outer cylinder is fitted around the spiral axis, and the sealing material that has moved along the spiral groove surely moves upward without escaping outside. That is, the sealing material is continuously fed toward the filling gun.

  Therefore, according to the present invention, since the sealing material is continuously fed from the tank toward the filling gun, the sealing material can be filled in the joints and joints by once opening the filling gun. It can be done in a short time with less labor.

  In addition, since the drive unit that drives the spiral shaft includes a coil body connected to the battery and is formed in a hollow shape so as to penetrate the spiral shaft, the spiral shaft is positioned as the drive shaft of the motor. The material feeding device can be configured compactly.

  Further, if the suction port has a plurality of blade portions, the sealing material in the tank can be stirred and the sealing material can be introduced into the spiral groove of the spiral shaft. In addition, since the guide surface formed between the blade portions is formed with a gradient that increases toward the destination, the sealing material can be moved and guided to the spiral groove as the spiral shaft rotates.

  Furthermore, according to the present invention, the sealing material fed from the sealing material feeding device reaches the filling port as it is in one flow path from the filling gun feed port, toward the joint or joint from the filling gun. Filled continuously. Therefore, since the work can be performed without performing manual work, the labor can be reduced and the work can be performed in a short time.

  The filling gun is turned on when the sealing material is filled, and turned off when filling is stopped. For this reason, the manual operation for the filling gun is only ON / OFF of the switch, and therefore no labor is used. Moreover, if the amount of the sealing material stored in the tank is set to an appropriate amount, the sealing material filling device itself can be carried. Easy and efficient work can be done in time.

  Next, an embodiment of a sealing material filling apparatus of the present invention will be described based on the drawings. The sealing material filling device of the embodiment (hereinafter simply referred to as a filling device) is a sealing material formed of a high-viscosity material on a joint of a concrete or a wall of a structure, a joint of a wall, or a joint of a tile or a sash. It is to be filled and improved so that it can be operated with less labor. The sealing material is composed of a two-component base and a curing agent, and a color master is mixed.

  FIG. 1 shows the entire filling device 1, and the sealing material M is stored in the tank 3. The tank 3 has a hand-held portion 31, and a 4 liter can or 6 liter can that stores a sealing material for approximately one day is used, and is easy to carry.

  The filling device 1 according to the embodiment includes a filling gun 5 for filling a sealing material M into joints and joints, and a sealing material feeding device (hereinafter referred to as a feeding device) 10 for feeding the sealing material M to the filling gun 5. ing. The filling gun 5 and the feeding device 10 are connected by a feeding pipe 7 through a coupling 8.

  The feeding device 10 of the embodiment is disposed at the above-described tank 3 that stores the sealing material M, the spiral shaft 12 that is configured to be rotatable, the outer cylinder 13 that is fitted around the spiral shaft 12, and the tip of the spiral shaft 12. A suction part 11 having a suction port 14, a battery 16 for rotationally driving the suction part 11, and a drive part 15 having a hollow coil body 17 connected to the battery 16 and inserted through the spiral shaft 12. It is configured.

  Around the coil body 17, a cover 18 having a cylindrical shape in a plan view extending from the upper surface of the coil body 17 to the lower end of the suction port 14 is disposed so as to surround the suction portion 11. The lower end of the cover 18 reaches the bottom of the tank 3, and an opening 181 for introducing the sealing material M into the cover 18 is appropriately formed on the lower side surface. Further, at the lower part of the cover 18, the sealing material M surrounds the upper part in the cover 18, that is, around the bottom surface of the spiral shaft 12 from the vicinity of the upper end surface of the opening 181 so as not to enter around the coil body 17. Thus, a bottom lid 182 is formed. The coil body 17 and the battery 16 are connected by a wiring member 19.

  A spiral groove 121 is formed on the spiral shaft 12 from the lower end to the upper end, and the sealing material M sucked from the tank 3 is moved into the spiral groove 121 so as to be fed upward. The outer cylinder 13 is externally fitted so as to be in close contact with the outer peripheral surface of the spiral shaft 12. By bringing the spiral shaft 12 into close contact with the outer cylinder 13, the spiral shaft 12 rotates together with it, and the sealing material M sent to the spiral groove 121 is not scattered by the rotation of the spiral shaft 12. Yes. Therefore, the sealing material M sent to the spiral groove 121 is efficiently and immediately sent upward.

  The suction port 14 is attached to the lower end of the spiral shaft 12, is rotated together with the spiral shaft 12, and is formed larger than the outer diameter of the spiral shaft 12. A blade member is used for the suction port 14 of the embodiment. In other words, the suction port 14 includes a blade portion 141 and a base plate 142 as shown in FIG. The blade portion 141 is formed in a curved shape in both a plan view and a side view, and has a concave surface on the back side with respect to the rotation direction. A surface formed between the blade portions 141 and 141 on the base plate 142 is formed as a guide surface 143 for guiding the sealing material M so as to move toward the spiral groove 121 of the spiral shaft 12. The guide surface 143 is formed with a gradient that increases from the peripheral edge toward the blade 141. For example, as shown in FIG. 4, the suction port 14 may have two blade portions 141 formed therein.

  The coil body 17 is configured to generate a magnetic field with the spiral shaft 12 when the coil in the coil body 17 is excited. The spiral shaft 12 and the coil body 17 of the embodiment constitute a motor, and the spiral shaft 12 is positioned as a drive shaft of the motor. A commercially available motor may be installed at a position away from the spiral shaft 12, and the drive shaft of the motor and the spiral shaft 12 may be connected by, for example, a belt and a pulley. However, installing a motor in a 4 liter can or 6 liter can reduces space efficiency, so the spiral shaft 12 is inserted into a hollow coil body 17 as shown in FIG. It is desirable to do.

  Since the spiral shaft 12 and the outer cylinder 13 are extended to the upper position of the tank 3 and are connected to the filling gun 5 through the feeding pipe 7, the outer cylinder 13 and the feeding pipe 7 are They are connected by a coupling 8. The coupling 8 is a commercially available one that includes a rotating portion 81 that fits on one end of the rotating outer cylinder 13 and a fixing portion 82 that fits on one end of the non-rotating feed pipe 7. Moreover, in order to move the filling gun 5 freely, the feeding pipe 7 is desirably a flexible pipe formed with flexibility.

  As shown in FIG. 2, the filling gun 5 has a main body case 51 that is pistol-shaped and has a supply-side case portion 51 a and a filling-side case portion 51 b and is formed in an approximately L shape. In the main body case 51, a supply port 52 connected to the supply pipe 7 and formed at the end of the supply-side case portion 51a, and a sealing material M formed at the end of the filling-side case portion 51b And a filling port 53 for filling. The supply port 52 and the filling port 53 are connected by a flow path (feed hole) 54. A filling nozzle 57 is attached to the filling port 53. A switch 55 is disposed in front of the supply-side case portion 51a. The switch 55 is disposed at the same position as a known pistol trigger.

  One end of a power cord 56 is connected to the switch 55, and the other end extends through the feed pipe 7 and reaches the coil body 17 side. A substrate (not shown) is disposed between the coil body 17 and the wiring member 19 connected from the battery 16, and connects the coil body 17, the power cord 56, and the wiring member 19. The circuit is formed so that the wiring member 19 and the coil body 17 are brought into conduction when the switch 55 is turned on, and the conduction between the wiring member 19 and the coil body 17 is released when the switch 55 is turned off.

  Next, the operation of the filling device 1 configured as described above will be described.

  A sealing material M is stored in the tank 3, a suction part 11 and a coil body 17 are mounted, and a battery 16 is connected to the coil body 17. Further, a filling gun 5 is connected to the upper side of the spiral shaft 12 through a feeding pipe 7.

  In this state, as shown in FIG. 5, the operator carries the filling device 1 by grasping the hand-held portion 31 of the tank 3 with his hand and moves to the work place. The operator who has moved to the work place holds the filling gun 5 with his hand and points the filling nozzle 57 toward the joint or joint to be filled, and then turns on the switch 55 of the filling gun 5.

  As shown in FIG. 1, when the switch 55 is turned on, the power source of the battery is transmitted to the coil body 17 and the coil body 17 is excited. The helical shaft 12 rotates together with the outer cylinder 13 and the suction port 14 by the excitation of the coil body 17. As the blade portion 141 in the suction port 14 rotates, the sealing material M in the tank 3 is agitated, and the sealing material M is guided by the blade portion 141 of the suction port 14 and introduced from the guide surface 143 to be spiral shaft. It feeds toward the 12 spiral grooves 121 (see FIG. 3). Since the guide surface 143 is formed with a gradient that increases from the outer peripheral edge along the spiral groove 121 side, the sealing material M is moved and guided along the gradient surface toward the spiral groove 121, and the spiral groove 121. Inserted into.

  Since the spiral shaft 12 is rotated, the sealing material M gradually moves upward along the spiral groove 121. At this time, since the outer peripheral surface of the spiral groove 121 is in close contact with the outer cylinder 13, the sealing material M inserted into the spiral groove 121 cannot escape from the spiral groove 121 and enters the spiral groove 121. It will move in order along.

  The sealing material M that has reached the upper end of the spiral groove 121 is further moved upward by the sealing material M pushed up from below and inserted into the feed pipe 7. As shown in FIG. 2, the sealing material M enters the flow path 54 from the supply port 52 of the filling gun 5 as it is, passes through the filling port 53, and is discharged to the outside from the filling nozzle 57. The sealing material M discharged to the outside is filled in the joint or joint by the operator's operation.

  The filling operation of the joint or joint is temporarily stopped by stopping the rotation of the spiral shaft 12 by the operator turning OFF the switch 55. When the operator turns on the switch 55 again, the filling operation is resumed.

  As described above, since the operator only needs to turn on / off the switch 55 of the filling gun 5, it can be performed by a simple operation and labor can be reduced. Further, since the filling device 1 can be carried by hand, it is not necessary to perform refilling work for replenishing the sealing material M, and it is not necessary to go to the tank 3. Therefore, the work place can be easily moved and the work can be performed efficiently.

  Further, since the helical shaft 12 can be rotated by the excitation of the coil body 17, the sealing material M can be continuously fed upward, and the spiral groove 121 and the outer circumferential surface of the spiral groove 121 are closed. By the outer cylinder 13, the sealing material M can be reliably sent toward the filling gun 5.

  Furthermore, since the sealing material M can be stirred by the rotation of the suction port 14 (blade part 141), it is possible to prevent the sealing material M stored in the tank 3 from being hardened quickly.

  In addition, the filling apparatus of this invention is not limited to the above-mentioned embodiment. For example, the blade portion used for the suction port may not be a blade shape as long as the sealing material can be stirred and introduced into the spiral groove. It is not limited to a single blade and may be more than that.
