The present invention relates to a sealing / pump-up device for increasing the internal pressure of a pneumatic tire by feeding compressed air into the tire.

In recent years, when a pneumatic tire (hereinafter simply referred to as “tire”) is punctured, the tire is repaired with a sealing agent and the internal pressure is pumped up to a specified pressure without replacing the tire and wheels. Pump-up devices are widespread. An example of this type of sealing / pump-up device is described in Patent Document 1.
JP 2005-344570 A

  By the way, the sealing / pump-up device usually includes a compressor that generates compressed air. The compressor is provided with a motor, and the driving force from the motor is transmitted to the gear, crank, and piston through a shaft connected to the motor.

  These components constituting the compressor are accommodated in the casing of the sealing / pump-up device, and are fixed to the casing via a frame covering these components.

  However, when the vibration of the motor is transmitted to the casing through the frame by driving the motor of the compressor, the vibration is transmitted to the repair liquid bottle through the casing. In particular, if vibration is applied to the repair solution when the atmospheric environment is high, gelling nuclei may be generated in the repair solution, and the tire may not be repaired successfully.

  An object of the present invention is to provide a pump-up device and a sealing / pump-up device that reduce the vibration of the compressor in consideration of the above facts.

  The invention according to claim 1 is a pump-up device capable of increasing the internal pressure of the pneumatic tire by sending compressed air into the pneumatic tire, and a compressor that generates the compressed air, and a vibration of the compressor that contains the compressor Vibration reducing means for reducing the vibration.

  In invention of Claim 1, after connecting a compressor and a pneumatic tire, the internal pressure of a pneumatic tire can be raised by sending the compressed air produced | generated with the compressor into a pneumatic tire. Here, the compressor is accommodated by vibration reducing means to reduce the vibration of the compressor.

  When a pneumatic tire is punctured, a sealing agent is injected into the tire through a compressor. By reducing the vibration of the compressor, the vibration transmitted to the sealing agent is reduced. Can be suppressed.

  According to a second aspect of the present invention, in the pump-up device according to the first aspect, the vibration reducing means is an elastic member that houses the motor of the compressor and elastically deforms to reduce vibration of the motor.

  In a second aspect of the present invention, the vibration reducing means is an elastic member that houses a compressor motor and elastically deforms to reduce vibration of the motor. Since the motor is a vibration generation source, reducing the vibration of the motor is more effective than reducing the vibration of other components constituting the compressor.

  According to a third aspect of the present invention, in the pump-up device according to the second aspect, the elastic member is elastically deformable along a reciprocating direction of a piston of the compressor.

  In the invention according to claim 3, the elastic member can be elastically deformed along the reciprocating direction of the piston of the compressor. Since the piston is connected to the motor, the motor is affected by the reciprocating movement of the piston, and vibrates along the reciprocating movement of the piston. By setting the direction in which the elastic member can be elastically deformed in accordance with the vibration direction of the motor, the vibration of the motor can be effectively reduced.

  According to a fourth aspect of the present invention, in the pump-up device according to the third aspect, the elastic member is a cylindrical body that is integrally provided in a casing of the main body of the apparatus, and the piston is provided on a peripheral wall of the cylindrical body. A slit is formed along a direction substantially orthogonal to the reciprocating direction.

Including cases.

  By forming a slit in the peripheral wall of the cylindrical body along a direction substantially orthogonal to the reciprocating direction of the piston, the cylindrical body can be enlarged in diameter around the slit. Since the cylindrical body is formed of an elastic member, restoring force is accumulated in the cylindrical body in a state where the diameter of the cylindrical body is expanded. As a result, the motor is securely held by the cylindrical body, a damping force acts on the vibration, and the vibration of the motor can be reduced.

  According to a fifth aspect of the present invention, in the pump-up device according to the fourth aspect, reinforcing ribs are formed on the inner peripheral surface of the cylindrical body along the axial direction of the cylindrical body.

  In the fifth aspect of the present invention, the strength of the cylinder can be increased by forming the reinforcing rib on the inner peripheral surface of the cylinder along the axial direction of the cylinder. As a result, the cylindrical body can be made thin and easily elastically deformed.

  The invention according to claim 6 is a sealing / pump-up device, wherein the compressed air generated by the compressor of the pump-up device according to any one of claims 1 to 5 is converted into a liquid container that contains a sealing agent. The sealing agent is injected into the pneumatic tire by being fed into the pneumatic tire.

  In order to repair a punctured pneumatic tire, first, after connecting the compressor of the pump-up device and the liquid container, the compressed air generated by the compressor is fed into the liquid container. And the sealing agent in a liquid agent container is extruded from a liquid agent container with compressed air, and is inject | poured into a pneumatic tire.

  After the sealing agent is exhausted from the liquid container, compressed air is sent into the pneumatic tire. When the pneumatic tire reaches the specified internal pressure, stop the compressor and disconnect the pneumatic tire from the liquid container. Thereafter, the pneumatic tire is mounted on the vehicle and the vehicle runs as prescribed. Thereby, the sealing agent is filled in the puncture holes. Check air pressure after the specified run and refill with air if necessary. In this way, repair of the punctured pneumatic tire is completed.

  Here, in the invention according to claim 6, by using the compressor of the pump-up device according to any one of claims 1 to 5, the vibration of the compressor is compared with the case where this configuration is not applied. Therefore, vibration transmitted to the liquid agent container is reduced, and gelling of the sealing agent can be suppressed.

  A seventh aspect of the present invention is the sealing / pump-up device according to the sixth aspect, wherein the liquid agent container is provided in a housing of the pump-up device according to any one of the first to fifth aspects. .

  In the invention according to claim 7, since the liquid container is provided in the casing of the pump-up device, the sealing / pump-up device is integrated, making it easy to carry the sealing / pump-up device and storing it in the storage location. Storability is improved.

  Since the present invention has the above configuration, the vibration of the compressor can be reduced.

(Compressor unit)
Next, the compressor unit 12 of the present invention will be described.

  As shown in FIG. 6, a reciprocating compressor 150 is used in the present embodiment. The compressor 150 includes a columnar motor 154 and can be accommodated in a cylindrical body (cylindrical body) 156 (described later) as vibration reducing means provided on the bottom plate 11 </ b> A of the casing 11.

  The motor 154 can be driven by electric power supplied from a power supply circuit. A cooling fan 160 is fixed to the lower portion of the rotating shaft 158 of the motor 154, and rotates with the driving of the motor 154 so that the motor 154 can be cooled. .

  Further, a pinion 162 is fixed to the upper portion of the rotation shaft 158 of the motor 154, and rotates with the driving of the motor 154. The pinion 162 meshes with a reduction gear 164 grasped as a reduction gear. A shaft 168 constituting the crankshaft 166 is fixed to the shaft portion of the reduction gear 164 and can be rotated integrally with the reduction gear 164.

  Further, the compressor 150 is provided with a substantially cylindrical crankcase 170 in which a crankshaft 166 and a cylinder 182 (described later) are accommodated. The crankcase 170 is provided with shaft plates 171 and 173 so as to surround the upper and lower surfaces of the pinion 162 and the reduction gear 164, and the shaft 168 is supported by a pair of bearings 172 provided on the shaft plates 171 and 173. Is rotatably supported.

  A double nut 175 is screwed into one end of the shaft 168 to maintain the screw tightening force and make it difficult to loosen the screw. A crank 174 that also serves as a counterweight is fixed to the other end of the shaft 168, and the crank 174 can rotate integrally with the shaft 168. Of course, the crank and the counterweight may be provided separately.

  The crank 174 is connected to one end portion of the piston rod 178 via a support pin 176 that is arranged with the shaft 168 and the shaft center shifted. The piston rod 178 is rotatable around the support pin 176. Here, a substantially columnar piston 180 is provided at the other end of the piston rod 178, and is accommodated in a substantially cylindrical cylinder 182 accommodated in the crankcase 170.

  When the crank 174 rotates through the pinion 162, the reduction gear 164, and the shaft 168 by driving the motor 154, the piston rod 178 moves through the support pin 176, but the movement is restricted by the piston 180 and cylinder 182 and the piston rod. 178 reciprocates while swinging. As a result, the piston 180 reciprocates within the cylinder 182.

  A cylinder chamber G is formed between the cylinder 182 and the piston 180, and the cylinder chamber G repeats expansion and contraction as the piston 180 reciprocates. A discharge port 184 for discharging the compressed air M is formed in the inner wall of the cylinder 182, and one end of a pressure-resistant pipe 186 is connected to the discharge port 184.

  The pressure-resistant pipe 186 is connected to the pressure-resistant hose 50 at the other end, and a check valve 188 is provided between the one end and the other end. The check valve 188 allows exhaust of the compressed air M from the discharge port 184 and can prevent the fluid (sealing agent 32) from entering the air supply path 50A.

  Specifically, the check valve 188 includes a valve body 190 that can close the passage of the pressure-resistant piping 186, and a biasing member 192 that biases the valve body 190 in a direction to close the passage (an example in this embodiment). As a spring).

  The piston 180 is formed with a through hole 194 penetrating in the axial direction. The through hole 194 serves as a suction port for sucking air into the cylinder chamber G (hereinafter referred to as “suction port 194”). It is used. The suction port 194 is provided with a suction valve 196 that allows air to be sucked into the cylinder chamber G and prevents leakage of air from the suction port 194.

  When the power switch 128 (see FIG. 1) is turned on while power is supplied to the power circuit of the compressor 150 configured as described above, the motor 154 rotates, and this rotation is reduced to an appropriate torque by the reduction gear 164. It is converted and transmitted to the shaft 168 of the crankshaft 166, and the crank 174 rotates through the shaft 168.

  Therefore, one end of the piston rod 178 connected to the crank 174 via the support pin 176 swings and reciprocates following the rotation of the crank 174. As a result, the piston 180 at the other end of the piston rod 178 reciprocates in the cylinder 182 along the arrow direction.

  Here, when the piston 180 is at the bottom dead center (a state where the piston 180 is closest to the opening side of the cylinder 182), the suction valve 196 is opened and air is sucked into the cylinder chamber G, and the check valve 188 is opened. Is closed (a state in which the valve body 190 closes the passage of the pressure-resistant piping 186).

  Further, when the piston 180 is at the top dead center (a state where the piston 180 is closest to the inner wall of the cylinder 182), the pressure of the compressed air M compressed in the cylinder chamber G with the intake valve 196 closed. As a result, the valve body 190 is moved in the anti-blocking direction, the passage of the pressure-resistant pipe 186 is opened (the check valve 188 is opened), and the compressed air M is sent to the pressure-resistant hose 50 through the discharge port 184 and the pressure-resistant pipe 186. It is.

  6 and 7, the motor 154 is housed in a cylindrical body 156 provided integrally with the casing 11, and the motor 154 is fixed so as to sandwich the motor 154. Here, the casing 11 and the cylindrical body 156 are formed of a material having higher toughness than ABS or the like, such as PP or PE.

  Here, “provided integrally with the casing 11” means that the cylindrical body 156 is fixed to the casing 11 by an adhesive or other fixing means in addition to the integral molding of the casing 11 and the cylindrical body 156. This includes cases where

  As shown in FIG. 8, a pair of slits 200 are provided on the peripheral wall of the cylindrical body 156 along the axial direction of the cylindrical body 156, and are formed at positions facing each other. Here, the slit 200 is formed along a direction substantially orthogonal to the reciprocating direction of the piston 180 (see FIG. 6). The slit 200 enables the cylindrical body 156 to expand in diameter. Note that the width, length, and the like of the slit 200 vary depending on the material of the cylindrical body 156, the thickness, and the like.

  The lower end portion of the slit 200 has an arc shape, and stress concentration is prevented from occurring at the lower end portion of the slit 200 in a state where the diameter of the cylindrical body 156 is increased. Further, a plurality of long plate-like reinforcing ribs 202 project from the inner peripheral surface of the cylindrical body 156 toward the axial center side of the cylindrical body 156 from the upper end portion to the lower end side of the cylindrical body 156. The strength of the cylindrical body 156 is improved by the reinforcing rib 202. A motor 154 is accommodated inside the reinforcing rib 202.

  Further, as shown in FIG. 7, a substantially rectangular parallelepiped support piece 204 projects horizontally from the lower end portion of each reinforcing rib 202 toward the axial center side of the cylindrical body 156. The outer shape of the cooling fan 160 is smaller than the inner diameter of the cylindrical body 156 and larger than the outer shape of the motor 154, and the blade portion 160 </ b> A of the cooling fan 160 passes between the adjacent reinforcing ribs 202. It is possible.

  A gap is provided between the lower surface of the support piece 204 of the reinforcing rib 202 and the bottom portion 156A of the cylindrical body 156 (the bottom plate 11A of the casing 11), and the accommodating portion 206 is provided by the gap. The cooling fan 160 is accommodated in the accommodating portion 206.

  The motor 154 is supported by the support piece 204 in a state where the cooling fan 160 is accommodated in the accommodating portion 206. In a state where the motor 154 is accommodated in the cylindrical body 156, the cylindrical body 156 expands within the elastic deformation around the slit 200.

  As shown in FIG. 9, a plurality of through holes 208 are formed in the bottom portion 156 </ b> A of the cylindrical body 156 at the lower portion of the support piece 204. The through-hole 208 has substantially the same shape as the support piece 204, so that the lower portion of the support piece 204 can be prevented from being a so-called undercut portion on the mold mechanism.

  In addition, a plurality of arc-shaped through-holes 210 are formed on the concentric circle of the axial center of the cylindrical body 156 in the bottom 156A. Outside air can be taken into the cylindrical body 156 by the through holes 208 and 210.

  As shown in FIG. 7, the reinforcing rib 202 formed in the cylindrical body 156 provides a gap t between the inner peripheral surface of the cylindrical body 156 and the motor 154, so that when the cooling fan 160 rotates, Since the outside air that has flowed in from the through holes 208 and 210 flows out to the outside air through the gap t, the motor 154 in the cylindrical body 156 can be sufficiently cooled.

  Next, an operation procedure for repairing the punctured tire 100 using the sealing / pump-up device 10 according to the present embodiment will be described.

  When the tire 100 is punctured, first, an operator places the sealing / pump-up device 10 on, for example, a road surface so that the power switch 128 and the pressure gauge 79 face upward (see FIG. 1). .)

  Next, as shown in FIG. 2, the valve adapter 80 of the joint hose 78 is screwed to the tire valve 102 of the tire 100. As a result, the pressurized liquid supply chamber 40 (see FIG. 3) and the tire 100 can communicate with each other through the joint hose 78.

  Next, the operator forcibly pushes the liquid agent container 18 downward by hand or the like (see FIG. 4). Thereby, the bridging portion 108A is pressed by the stopper pin 112 and is broken, and the injection unit 20 moves downward while being guided by the guide pin 110. Along with this movement, the pressing jig 82 pushes up the piercing part 98, and the perforated part 98B of the piercing part 98 breaks through the aluminum seal 30 and enters the container.

  As shown in FIG. 4, when the aluminum seal 30 is pierced, the sealing agent 32 in the liquid agent container 18 flows out to the pressurized liquid supply chamber 40 through the hole 31 formed in the aluminum seal 30.

  Further, when the liquid container 18 is pushed in, the claw portion 126B of the flange lock claw 126 formed on the bottom plate 11A of the casing 11 is hooked on the edge portion of the long hole 106 formed in the flange 36, and the protrusion of the liquid container 18 114 gets over the tip of the claw 124 formed in the liquid container insertion hole 122 of the casing 11, and the tip of the claw 124 contacts the flat portion 118 of the upper projection 114.

  After pushing the liquid container 18 in this way, the power switch 128 is turned on and the compressor unit 12 is operated. The compressed air generated by the compressor unit 12 is supplied into the liquid agent container 18 through the jig communication path 88.

  When the compressed air is supplied into the liquid agent container 18, the compressed air floats above the sealing agent 32 in the liquid agent container 18 and forms a space (air layer) on the sealing agent 32 in the liquid agent container 18. The sealing agent 32 pressurized by the air pressure from the air layer is supplied into the pressurized liquid supply chamber 40 through the hole 31 formed in the aluminum seal 30, and passes through the joint hose 78 from the pressurized liquid supply chamber 40. And injected into the pneumatic tire 100.

  Further, when compressed air is supplied into the liquid agent container 18, pressure is applied to the upper end of the pressing jig 82 to force the pressing jig 82 to come out of the jig insertion hole 44, that is, the liquid agent container 18 and the injection unit 20 are moved upward. However, the tip of the claw 124 of the casing 11 comes into contact with the flat portion 118 of the projection 114 to prevent the liquid agent container 18 from moving upward, and the flange provided on the bottom plate 11A of the casing 11 Since the claw portion 126B of the lock claw 126 is caught by the edge portion of the long hole 106 of the flange 36 and prevents the injection unit 20 from moving upward, the pressing jig 82 comes out of the jig insertion hole 44 and the sealing agent 32 is inserted into the jig. Leaking out of the apparatus through the hole 44 is prevented.

  In addition, after all the sealing agent 32 in the liquid container 18 is discharged, the sealing agent 32 in the pressurized liquid supply chamber 40 is pressurized and supplied into the pneumatic tire 100 through the joint hose 78. When all the sealing agent 32 is discharged from the pressurized liquid supply chamber 40 and the joint hose 78, the compressed air is injected into the tire 100 through the liquid agent container 18, the pressurized liquid supply chamber 40, and the joint hose 78. .

  Next, when it is confirmed by the pressure gauge 79 that the internal pressure of the tire 100 has become the specified pressure, the operator stops the compressor unit 12 and removes the valve adapter 80 from the tire valve 102.

  The worker travels preliminarily for a certain distance using the tire 100 into which the sealing agent 32 has been injected within a certain time after the completion of the inflation of the tire 100. As a result, the sealing agent 32 is uniformly diffused inside the tire 100, and the sealing agent 32 is filled in the puncture hole to close the puncture hole.

  After completion of the preliminary traveling, the operator re-measures the internal pressure of the tire 100, screwes the valve adapter 80 of the joint hose 78 to the tire valve 102 again as necessary, and restarts the compressor unit 12 to remove the tire 100. Pressurize to the specified internal pressure. Thereby, the puncture repair of the tire 100 is completed, and the tire 100 can be used to travel at a certain speed or less (for example, 80 km / h or less) within a certain distance range.

  Next, the operation of this embodiment will be described.

  As shown in FIGS. 6 to 8, in this embodiment, a cylindrical body 156 is provided integrally with the casing 11, and a motor 154 is accommodated and fixed in the cylindrical body 156. A slit 200 is formed on the peripheral wall of the cylindrical body 156 along a direction substantially orthogonal to the reciprocating direction of the piston 180.

  Since the crank 174 functions as a counterweight, the inertial force generated by the vibration of the piston 180 and the piston rod 178 is reduced, and when the crankshaft 166 rotates, the rotation balance is achieved to suppress the vibration. However, the reciprocating movement of the piston 180 has a considerable influence on the motor 154.

  Since the motor 154 vibrates in a direction orthogonal to the axial direction of the motor 154 along the reciprocating movement of the piston 180, the cylindrical body 156 is elastically deformed in accordance with the vibration direction of the motor 154. The vibration of 154 is reduced.

  Since the cylindrical body 156 is formed of a resin having high toughness such as PP and PA, it can be elastically deformed. By forming the slit 200 on the peripheral wall of the cylindrical body 156, the cylindrical body 156 is formed around the slit 200. Can be expanded in diameter. Since the restoring force is accumulated in the cylindrical body 156 in a state where the inner diameter of the cylindrical body 156 is widened, the motor 154 is securely held by the cylindrical body 156, and the damping force is reduced with respect to the vibration of the motor 154. It acts, and the vibration of the motor 154 can be reduced.

  Further, by forming a pair of slits 200 at positions facing each other on the peripheral wall of the cylindrical body 156 with the axial center of the cylindrical body 156 as the center, the diameter can be expanded with a good balance in the left and right directions with the slit 200 as the center. The effect of absorbing the vibration of 154 can be exhibited most effectively. Here, although a pair of slits 200 is provided at positions facing each other on the peripheral wall of the cylindrical body 156 with the axial center of the cylindrical body 156 as the center, depending on the size of the cylindrical body 200 and the like, the slit 200 may be 3 Two or more may be provided. However, in this case, the slits 200 are preferably provided at equal intervals along the circumferential direction of the cylindrical body 156.

  A reinforcing rib 202 is formed on the inner peripheral surface of the cylindrical body 156 along the axial direction of the cylindrical body 156. In order to make the cylindrical body 156 easily elastically deformed, it is better to make the thickness of the cylindrical body 156 as thin as possible. However, if the cylindrical body 156 is made too thin, the holding force to the motor 154 will be reduced. However, by providing the reinforcing rib 202 on the cylindrical body 156, the strength of the cylindrical body 156 can be improved and the cylindrical body 156 can be made thin.

  Here, since the motor 154 is a vibration generation source, in reducing the vibration to the casing 11, among the plurality of components constituting the compressor 150, it is possible to reduce the vibration of the motor 154 in another configuration. This is more effective than the case of reducing the vibration of the parts. However, reduction of vibrations of components other than the motor 154 is not denied.

In the sealing / pump-up device 10, the compressed air generated by the compressor 150 is sent to the pneumatic tire 100 through the liquid container 18 that contains the sealing agent 32, so that the sealing agent 32 is injected into the pneumatic tire 100. Since the vibration of the compressor 150 can be reduced as compared with the case where this configuration is not applied, the vibration transmitted to the liquid agent container 18 through the casing 11 is reduced, and the gelation of the sealing agent 32 is suppressed. be able to.

The cylindrical body 156 can be elastically deformed in the direction in which the inner diameter of the cylindrical body 156 increases. However, when the piston 180 reciprocates along the vertical direction, the cylindrical body 156 needs to be elastically deformable in the axial direction. There is.

  In this case, for example, as shown in FIG. 11, as shown in FIG. 11, a bellows portion 218 that can expand and contract in the axial direction of the housing portion 216 is formed at the center portion of the cylindrical housing portion 216 that can accommodate the motor 154. The portion 216 is made elastically deformable in the axial direction.

  In addition to this, although not shown, a plurality of long holes are formed in the circumferential wall of the cylindrical body along the circumferential direction, and a plurality of the long holes are provided along the axial direction, and are arranged in a staggered manner in the axial direction. In this way, the cylindrical body may be elastically deformable in the axial direction.

  Further, in the present embodiment, the sealing / pump-up device is an integrated sealing / pump-up device in which the liquid container 18 having the compressor and the injection unit 20 fixed thereto is provided in the casing 11, but the present invention has this configuration. Without being limited thereto, a sealing / pump-up device that accommodates the liquid agent container 18 to which the compressor and the injection unit 20 are fixed in separate casings may be used.
