Abstract

<P>PROBLEM TO BE SOLVED: To provide a sealing pump-up device allowing a worker to know that pressure in a tire reaches a specified pressure without visually checking a pressure gauge. <P>SOLUTION: When a compressor unit supplies compressed air to a liquid medicine container, the air pressure of the compressed air first exceeds specified pressure in the tire and passes through a scale where an indicator 100 indicates the specified pressure in the tire, although pressure in the pneumatic tire does not reach the specified pressure because of the resistance of sealing agent. Thus, an electric current flows between the indicator 100 and an electrode 104 contacting each other but it is stored in a capacitor 110 to preclude the operation of an alarm buzzer 112. After supplying the sealing agent, the pressure in the tire is gradually increased up to the specified pressure and the indicator 100 is also gradually moved toward the scale to indicate the specified pressure in the tire. When the indicator 100 points the scale to indicate the specified pressure in the tire, an electric current flows between the indicator 100 and the electrode 104 contacting each other so that the alarm buzzer 112 is operated to inform the worker that the pressure in the tire reaches the specified pressure. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a sealing and pump-up device for injecting a sealing agent for sealing a punctured pneumatic tire into the pneumatic tire and then supplying compressed air into the pneumatic tire to increase the internal pressure of the pneumatic tire. About.

  Patent Document 1 describes a sealing / pump-up device that, when a pneumatic tire is punctured, repairs the tire with a sealing agent and pumps the tire internal pressure up to a specified pressure without replacing the tire and the wheel. Yes.

Specifically, the sealing / pump-up device is provided with a pressure gauge that displays the internal pressure in the tire that has been increased by the compressed air.
Then, the operator visually checks the pressure gauge to confirm that the internal pressure of the tire has become the specified pressure, and turns off the power switch to stop the compressor unit.

JP 2008-175345 A JP 2006-1269 A

  However, in the conventional sealing and pump-up device, the pressure gauge confirms that the internal pressure of the tire has reached the specified pressure, and the power switch is turned off. I had to look at the gauge.

  In view of the above facts, the present invention has a problem of knowing that the internal pressure of the tire has reached the specified pressure without the operator viewing the pressure gauge.

  The sealing / pump-up device according to claim 1 of the present invention includes an air supply source for supplying compressed air and a sealing agent, and compressed air is supplied from the air supply source and connected to a pneumatic tire. A liquid container for supplying the sealing agent to the pneumatic tire through a connection hose, a pressure display panel having a scale for displaying the air pressure of the compressed air supplied from the air supply source, and a compression supplied from the air supply source A pointer indicating the scale based on the air pressure of compressed air, and a pointer provided on the pressure display panel, the pointer indicating the scale indicating the designated pressure of the pneumatic tire. An electrode through which electricity flows through contact with the pointer, and is provided between the electrode and the pointer, and stores electricity flowing between the electrode and the pointer, A capacitor for outputting by delaying the air, characterized in that it and a warning member actuated by electrical output with a delay by the capacitor.

  According to the said structure, an air supply source supplies compressed air to a liquid agent container. As a result, the sealing agent and compressed air stored in the liquid container are supplied to the punctured pneumatic tire through the connection hose connected to the pneumatic tire.

  Further, the pointer operates based on the air pressure of the compressed air supplied from the air supply source to the liquid agent container, and the compressed air supplied from the air supply source to the liquid agent container by reading the scale on the pressure display panel indicated by the operated pointer. Air pressure is confirmed.

When the pointer points to the scale indicating the designated pressure of the pneumatic tire, the pointer and the electrode are brought into contact with each other, and electricity is conducted between the pointer and the electrode.
Furthermore, electricity is output between the pointer and the electrode after being delayed by a capacitor. Then, the warning member is actuated by electricity outputted with a delay to notify the worker that the internal pressure of the pneumatic tire has reached the specified pressure.

  Here, when the air supply source supplies compressed air to the liquid agent container, first, the sealing agent accommodated in the liquid agent container is supplied to the pneumatic tire by the air pressure of the compressed air. When the supply of the sealing agent to the tire is completed, compressed air is supplied to the pneumatic tire in order to increase the internal pressure of the pneumatic tire to a specified pressure.

  That is, first, the sealing agent contained in the liquid container must be supplied to the pneumatic tire by the air pressure of the compressed air supplied from the air supply source. Therefore, even though the internal pressure of the pneumatic tire does not reach the specified pressure due to the resistance of the sealing agent, the air pressure of the compressed air supplied from the air supply source exceeds the specified pressure of the pneumatic tire. It is conceivable to temporarily pass a scale indicating the designated pressure of the pneumatic tire.

  However, as described above, since the capacitor delays and outputs the electricity flowing between the pointer and the electrode, the electrode and the pointer are temporarily in contact with each other when the pointer passes the scale indicating the designated pressure of the pneumatic tire. However, the warning member does not work.

  In addition, when the supply of the sealing agent to the tire is completed, the resistance of the sealing agent disappears, so the air pressure of the compressed air supplied from the air supply source drops, and the pointer again passes the scale indicating the specified pressure of the pneumatic tire By doing so, the electrode and the pointer are in temporary contact. When the electrode and the pointer are temporarily in contact with each other, electricity temporarily flows between the pointer and the electrode, but the warning member is not activated by the capacitor as described above.

  After the supply of the sealing agent to the tire is completed, compressed air is supplied from the air supply source to the pneumatic tire in order to increase the internal pressure of the pneumatic tire to the specified pressure.

  As the compressed air is supplied and the internal pressure of the pneumatic tire gradually increases, the pointer gradually moves toward the scale displaying the designated pressure of the pneumatic tire. When the pointer indicates a scale indicating the designated pressure of the pneumatic tire, the pointer and the electrode come into contact with each other, and electricity flows between the pointer and the electrode.

When electricity flows between the pointer and the electrode, the warning member is activated by the electricity output delayed by the capacitor.
Thus, by operating the warning member when the internal pressure of the pneumatic tire reaches the specified pressure, the operator can know that the internal pressure of the tire has reached the specified pressure without looking at the pressure gauge. it can.

  The sealing / pump-up device according to claim 2 of the present invention is the warning according to claim 1, wherein the warning member generates a sound to notify an operator that the internal pressure of the pneumatic tire has reached a specified pressure. It is a buzzer.

According to the above configuration, the warning buzzer generates a sound so that the worker knows that the internal pressure of the pneumatic tire has reached the specified pressure.
Thus, the operator can know that the internal pressure of the tire has reached the specified pressure without looking at the pressure gauge.

  The sealing / pump-up device according to claim 3 of the present invention is the sealing / pump-up device according to claim 1, wherein the warning member stops the supply of compressed air from the air supply source to the pneumatic tire to allow the operator to enter the air. It is an air supply source stop member that notifies that the internal pressure of the tire has reached a specified pressure.

  According to the above configuration, the operator knows that the internal pressure of the pneumatic tire has reached the specified pressure by stopping the supply of compressed air from the air supply source to the pneumatic tire.

  Thus, the operator can know that the internal pressure of the tire has reached the specified pressure without looking at the pressure gauge.

  According to the present invention, the operator can know that the internal pressure of the tire has reached the specified pressure without looking at the pressure gauge.

As shown in FIG. 5, the base end side of the liquid agent discharge port 74 is inserted into the pressurized liquid supply chamber 40. Thus, the joint hose 78 communicates with the pressurized liquid supply chamber 40 through the liquid agent discharge port 74.

(Jig)
Next, the jig 82 used when the sealing agent 32 flows out from the sealing device 10 will be described.

As shown in FIG. 3, the jig 82 is fitted into the side portion of the casing 10 </ b> A of the sealing device 10 when not in use, and is removed from the side and used during use.
As shown in FIG. 6, the jig 82 includes a rod-shaped insertion portion 84 to be inserted into the jig insertion hole 44 and a substantially rectangular base portion 86 formed at the base end portion of the insertion portion 84.

  The insertion portion 84 is formed with a jig communication path 88 that extends from the distal end surface toward the base portion 86 and bends and extends toward the outer peripheral side at the intermediate portion. An annular communication groove 90 serving as an air passage is formed in the opening portion of the jig communication passage 88 on the outer peripheral surface of the insertion portion 84.

  On the outer peripheral surface of the insertion portion 84, insertion grooves are formed on the upper side and the lower side of the communication groove 90, and O-rings 96 are inserted into the pair of insertion grooves.

  As shown in FIGS. 6C and 6D, the outer contour of the distal end portion 85 of the insertion portion 84 has a shape in which the diameter increases from the distal end toward the base portion 86, that is, the distal end portion 85 has a substantially conical shape. ing. A stepped portion 85A is formed at the boundary between the distal end portion 85 and the other portion of the insertion portion 84, and the diameter of the outer peripheral end of the stepped portion 85A is larger than the diameter of the inner peripheral end of the ridge portion 44A.

(Main part)
Next, the pressure gauge 16 that displays the air pressure of the compressed air supplied to the liquid supply unit 11 by the compressor unit 12 will be described.

  As shown in FIG. 1A, the pressure gauge 16 is provided with a pointer 100 that rotates based on the air pressure of compressed air supplied from the compressor unit 12. Further, a circular pressure display panel 102 having a scale 102A for displaying the air pressure of the compressed air corresponding to the rotational position of the pointer 100 is disposed on the mounting surface to which the rotary shaft 100A of the pointer 100 is rotatably mounted.

  Further, a capacitor 110 is provided between the pointer 100 and the electrode 104 to store electricity flowing between the resistor 108 and the pointer 100 and the electrode 104 for a predetermined time (in this embodiment, 5 seconds). In addition, a warning buzzer 112 is provided that is activated to generate a warning sound when the electricity stored by the capacitor 110 reaches a predetermined amount.

(Action / Effect)
Next, a sealing agent injection method for injecting a sealing agent into the tire 14 punctured using the sealing device 10 according to the present embodiment and a work procedure for repairing the tire 14 will be described.

As shown in FIG. 2, the worker attaches the valve adapter 70 provided at the tip of the joint hose 78 to the tire valve of the punctured tire 14.
Next, as shown in FIG. 7, the operator removes the jig 82 fitted in the housing 10 </ b> A, and inserts the insertion portion 84 of the jig 82 into the jig insertion hole 44 of the sealing device 10.

  When the insertion portion 84 presses the piercing member 62, the shaft portion 63 of the piercing member 62 changes in diameter (reduced diameter), and the projection 63B gets over the ridge 44A. Then, the piercing member 62 moves toward the seal member 30 while being pressed by the distal end portion 85 of the insertion portion 84. The diameter-reduced distal end portion 85 passes through the jig insertion hole 44 and then returns to its original diameter due to its own elasticity.

  When the claw 83A exceeds the leg portion 36, the inclined surface of the claw 83A is pushed by the outer peripheral surface 36A of the leg portion 36 and the support column 83 is elastically deformed, but the base portion 86 of the jig 82 is the leg of the injection unit 20. When the claw 83A passes through the outer peripheral surface 36A of the leg portion 36 and is inserted until it hits the portion 36, the column 83 returns to its original elasticity, and the claw 83A is caught on the edge of the leg portion 36, and the jig 82 is pulled out. To prevent movement.

  As a result, as shown in FIG. 8, the piercing portion 66 of the piercing member 62 pushed by the insertion portion 84 pierces the seal member 30 and is pushed into the container, and the distal end portion 85 of the insertion portion 84 is inside the liquid container 18. Get in. At this time, the jig 82 presses the pair of O-rings 96 arranged on the outer peripheral surface of the insertion portion 84 against the inner peripheral surface of the jig insertion hole 44, and the insertion portion 84 is an end portion on the inlet side of the jig insertion hole 44. The O-ring 96 disposed on the upper side of the insertion portion 84 is passed through the inner peripheral side of the air supply port 58 during the movement.

  Thereafter, the sealing device 10 is disposed, for example, on the road surface or the like so that the leg portion 36 is downward and the liquid agent container 18 is upward.

  When the insertion portion 84 of the jig 82 is inserted into the jig insertion hole 44 of the injection unit 20, the distal end portion 85 of the insertion portion 84 protrudes from the distal end of the inner peripheral cylindrical portion 42 as shown in FIGS. 7 and 8. At the same time, it passes through the hole 31 formed in the seal member 30 by the piercing member 62 and enters the liquid agent container 18. Then, the sealing agent 32 in the liquid container 18 flows into the pressurized liquid supply chamber 40 through the hole 31.

  Next, the switch 48 shown in FIG. 3 is turned on to operate the compressor unit 12, and the compressed air passes through the pressure hose 50 (see FIG. 5) and the jig communication path 88 (see FIG. 7) into the liquid agent container 18. Supplied.

  Further, as shown in FIG. 8A, when 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 the sealing in the liquid agent container 18 is performed. A space (air layer) is formed on the agent 32. The sealing agent 32 pressurized by the air pressure from the air layer is supplied to the pressurized liquid supply chamber 40 through the hole 31 formed in the seal member 30, and from the inside of the pressurized liquid supply chamber 40 through the joint hose 78. It is injected into the pneumatic tire 14.

  Here, although the internal pressure of the pneumatic tire 14 does not reach the specified pressure due to the resistance of the sealing agent 32, the air pressure of the compressed air flowing through the pressure-resistant hose 50 exceeds the specified pressure of the pneumatic tire 14.

  As shown in FIGS. 1A, 1B, and 1C, when the compressed air pressure exceeds the specified pressure of the pneumatic tire 14, the pointer 100 of the pressure gauge 16 is shown in FIG. The electrode 104 is temporarily brought into contact with the electrode 104 by passing through the scale 102A that rotates and moves from the initial position shown and displays the designated pressure of the pneumatic tire and reaches the position shown in FIG.

  However, since electricity is stored in the capacitor 110 as described above, when the pointer 100 passes the scale 102A indicating the designated pressure of the pneumatic tire, the electrode 104 and the pointer are temporarily in contact with each other, and the pointer 100 and the electrode 104 Even if electricity flows during this period, the warning buzzer 112 does not operate.

  Further, when the supply of the sealing agent 32 (see FIG. 5) to the tire 14 is finished, the resistance of the sealing agent 32 is lost, so the air pressure of the compressed air supplied from the compressor unit 12 (see FIG. 4) decreases, and the needle 100 Moves from the position shown in FIG. 1C to the position shown in FIG. When the needle 100 moves from the position shown in FIG. 1C to the position shown in FIG. 1A, the pointer 100 passes through the scale 102A displaying the designated pressure of the pneumatic tire again and temporarily passes the electrode 104. And the pointer 100 touch. When the electrode 104 and the pointer 100 are in temporary contact, electricity temporarily flows between the pointer 100 and the electrode 104. However, since the electric potential is stored in the capacitor as described above, the warning buzzer 112 does not operate.

  After the supply of the sealing agent 32 to the tire 14 is completed, compressed air is supplied from the compressor unit 12 to the pneumatic tire 14 in order to increase the internal pressure of the pneumatic tire 14 to a specified pressure.

  When the compressed air is supplied and the internal pressure of the pneumatic tire 14 gradually increases, the pointer 100 also gradually rotates and moves toward the scale 102A that displays the designated pressure of the pneumatic tire. As shown in FIG. 1B, when the pointer 100 indicates a scale 102A that displays the designated pressure of the pneumatic tire 14, the pointer 100 and the electrode 104 are in contact with each other, and electricity flows between the pointer 100 and the electrode 104. When the electricity stored in the capacitor 110 reaches a predetermined amount, the warning buzzer 112 generates a warning sound.

  Thus, the warning buzzer 112 generates a warning sound, so that the operator knows that the internal pressure of the tire 14 has become the specified pressure, turns off the switch 48, stops the compressor unit 12, and the valve adapter 70. Remove from the tire valve.

  Then, the operator travels preliminarily for a certain distance (for example, 10 km) using the tire 14 injected with the sealing agent 32 within a certain time after the completion of the inflation of the tire 14. As a result, the sealing agent 32 is uniformly diffused inside the tire 14, and the sealing agent 32 is filled in the puncture hole, thereby closing the puncture hole.

  If the internal pressure of the tire 14 is less than the prescribed pressure after the preliminary traveling is completed, the operator connects the valve adapter 70 of the joint hose 78 to the tire valve of the tire 14 as shown in FIG. The compressor unit 12 is turned on to pressurize the tire 14 to a specified internal pressure. Thereby, the puncture repair of the tire 14 is completed, and the tire 14 can be used to travel at a constant speed or less (for example, 80 km / h or less) within a certain distance range.

  In this way, the warning buzzer 112 informs the worker that the internal pressure of the pneumatic tire 14 has reached the specified pressure, so that the worker has reached the specified pressure of the tire 14 without looking at the pressure gauge 16. I can know that.

  Further, even if the compressed air pressure temporarily supplied from the compressor unit 12 exceeds the specified pressure of the pneumatic tire 14 due to the resistance of the sealing agent 32, the capacitor 110 stores electricity, so that the warning buzzer 112 malfunctions. Can be prevented.

  In addition, a capacitor 110, a resistor 108, and a warning buzzer 112 are added, and an inexpensive configuration can be achieved by using a general-purpose product.

  Although the present invention has been described in detail with respect to specific embodiments, the present invention is not limited to such embodiments, and various other embodiments are possible within the scope of the present invention. It is clear to the contractor. For example, in the above embodiment, the warning buzzer 112 notifies the worker that the internal pressure of the tire 14 has reached the specified pressure. However, an air supply source stop member that stops the compressor unit 12 is provided to stop the compressor unit 12. The operator may be notified, and further, the operator may be notified by combining the warning buzzer 112 and the stop of the compressor unit 12.

  In the above embodiment, the time for which the capacitor 110 stores electricity is 5 seconds. However, the present invention is not limited to this, and the air pressure of the compressed air increases due to the resistance of the sealing agent 32, and the pointer 100 reciprocates the electrode 104. The time is not limited to 5 seconds as long as it is longer than the passing time.
