Description

  The present invention relates to an air hose reel, and more particularly to an air hose reel having an auxiliary tank.

  In recent years, in order to increase the fastening strength between members to be constructed, pneumatic tools tend to use long nails and screws, which are fastening members, and those having a large outer diameter. Accordingly, the amount of air used in pneumatic tools has increased, and air supply cannot catch up with only general-pressure air compressors, and high-pressure compressors and corresponding pneumatic tools have been put on the market and have become widespread.

  However, if further shortening of the work period is required and the work is to be speeded up, there is a frequent problem that the work is interrupted until the supply amount of air is insufficient and the compressor accumulates a predetermined air pressure. It was causing a decline. For this reason, an auxiliary tank is arranged between the pneumatic tool and the compressor to make up for the shortage of air volume, thus eliminating this problem.

  In addition, since the compressor has to be enlarged in order to improve the air supply capacity, the compressor becomes heavier and an auxiliary tank is added, so it is not easy to move. Therefore, in a construction site such as a house, a compressor and an auxiliary tank can be carried in and installed on the first floor of the house, but it is not easy to carry in the second floor.

  Therefore, a long hose is connected to the auxiliary tank connected to the compressor on the first floor and is extended to the second floor. As this hose is extended, it is necessary to consider handling, carrying, and adjusting the length according to the work site. It is common to use it efficiently.

As a result, the worker must carry in, install, and take out the entire system composed of a pneumatic tool, an air compressor, an auxiliary tank, and a hose reel in order to use the pneumatic tool. It was a big burden. In order to solve this problem, as disclosed in Patent Document 1, an air hose winder having an air tank is disclosed.

  However, since the operator has both general pressure and high pressure pneumatic tools, the above-described air hose reel can use only one nailing machine. For this reason, the operator had to obtain two types of air hose reels with built-in auxiliary tanks and carried them both to the construction site, which caused new problems.

  Therefore, an object of the present invention is to provide an air hose reel that can use both a general pressure tool and a high pressure tool.

The high-pressure pressure reducing valve and the general pressure pressure-reducing valve are respectively provided in the first rotary shaft portion, and the first rotary shaft portion is formed with an air passage through which compressed air flows from the compressor into the tank. In addition, it is preferable that a high pressure air passage and a general pressure air passage capable of transferring compressed air from the air passage to the high pressure pressure reducing valve and the general pressure pressure reducing valve are formed.

  According to such a configuration, the tank can be easily supported on the frame, and the portion connecting the tank and the external compressor can be easily configured. Moreover, the operability at the time of pressure adjustment can be improved by collecting the pressure reducing valves for adjusting the pressure in one place.

  Moreover, this tank may be comprised so that both of this high pressure hose and this general pressure hose can be wound around the outer periphery of this cylindrical wall part.

  According to such a configuration, since both air hoses can be wound around the tank, the transportability of the air hose reel with the air hose can be improved, and the air hose reel can be moved and the pneumatic tool can be prepared and connected. Time can be further reduced.

  The drain mechanism 6 mainly includes a discharge port portion 61, a first passage formation portion 62, a connection portion 63, a discharge passage portion 64, a water intake portion 65, and a drain valve 66. The discharge port portion 61 forms a discharge port 61 a that is released to the atmosphere and discharges water generated in the tank 3. The 1st channel | path formation part 62 is arrange | positioned along the center axis | shaft C at the 2nd axial part 32 of 3 tanks, and is equipped with the discharge port 61a in the end. Further, the first passage forming portion 62 has the other end protruding into the air chamber 3a and forms a first passage 32a which is a part of the discharge passage. The connecting portion 63 constitutes a second passage forming portion together with the lead-out passage portion 64, is provided at the other end of the first passage forming portion 62, and is configured to be rotatable around the central axis C. Further, the connection portion 63 is formed with an inflow port 63b whose opening direction opens in a direction substantially orthogonal to the central axis C, and a connection passage 63a that connects the inflow port 63b and the first passage 32a is formed.

It is composed of a flexible resin material so as to communicate with each other. A second passage is defined by the connection passage 63a and the lead-out passage 64a.

  The water intake portion 65 is attached to the other end of the lead-out passage portion 64, and is arranged so that the end portion on the side opposite to the connection portion 63 slightly contacts the inner peripheral surface of the trunk portion 3A. Therefore, in the drain mechanism 6, the distance from the central axis C to the end position of the water intake portion 65 is configured to be substantially equal to the distance from the central axis C to the inner surface of the trunk portion 3 </ b> A.

  In addition, since the water intake portion 65 is configured by sintering powder metal, it is a heavy weight and porous, and can suck moisture and gas from its surface. An opening 65a is formed at a position facing the inner peripheral surface of the body portion 3A of the water intake portion 65, and the opening 65a communicates with the outlet passage 64a. In the intake portion 65 which is a heavy object, the connection portion 63 connected via the lead-out passage portion 64 is supported by the first passage formation portion 62 so as to be rotatable around the central axis C, so that the handle 32A is rotated. Even if the tank 3 including the first passage forming portion 62 rotates, the tank 3 always hangs down without being rotated, and is positioned at the lowermost portion in the air chamber 3a.

  The drain valve 66 is provided on the first passage 32a and selectively controls closing and communication of the first passage 32a.

  When working with the air hose reel 1 having the above-described configuration, the tank 3 is first rotated so as to pull out the high-pressure hose 52 for a predetermined working length, and then the air hose 11A from the air compressor 11 is freely rotatable. Connected to 31 A, the compressed air is stored in the tank 3. At the same time, the general pressure nail driver 12 and the high pressure nail driver 13 are connected to the general pressure female coupler 42 and the high pressure female coupler 53, respectively, and work is performed.

  At this time, in the general pressure nailer 12, the compressed air stored in the air chamber 3 a flows into the general pressure reducing valve 41 through the air passage 31 a and the general pressure air passage 31 b, and from the general pressure reducing valve 41. The pressure is reduced to a predetermined pressure (about 0.39 to 0.98 MPa) and discharged from the general pressure female coupler 42, and the compressed air is sent to the general pressure nail driver 12 via the general pressure hose 12A. In the high-pressure nailer 13, the compressed air stored in the air chamber 3a flows into the high-pressure pressure reducing valve 51 through the air passage 31a and the high-pressure air passage 31c. The pressure is reduced to about 0.98 to 2.45 MPa and discharged into the high-pressure hose connection passage 51a, and the high-pressure hose 52 and the high-pressure female are discharged from a discharge port (not shown) located at the end of the high-pressure passage formation portion 52A. Compressed air is sent to the high pressure nailer 13 through the coupler 53. Therefore, two types of pneumatic tools for general pressure and high pressure can be used with one air hose reel 1. In addition, by using one air hose reel 1, two types of tools, that is, a pneumatic tool for high pressure and a pneumatic tool for general pressure can be used simultaneously.

  After the work is finished, the general pressure nail driver 12 and the high pressure nail driver 13 are removed, the tank 3 is rotated by the handle 32, and the high pressure hose 52 is wound around the reel portion 3D.

  At the time of winding, the first passage forming portion 62 is also rotated at the same time by the rotation of the tank 3. However, since the connecting portion 63 is rotatably attached to the first passage forming portion 62, the water intake connected to the connecting portion 63. The part 65 is always arranged at the bottom. Since the water intake unit 65 is disposed at a position that slightly contacts the inner peripheral surface of the tank 3, the tank 3 and the water intake unit 65 are prevented from coming into contact with each other during rotation. Further, since the air hose relating to at least one of the pneumatic tools can be taken up, the time required for moving the air hose reel 1 and preparing / connecting the general pressure nailing machine 12 and the high pressure nailing machine 13 can be reduced. .

  Thereafter, the drain valve 66 is twisted, and the water generated in the air chamber 3a is discharged from the discharge port 61a together with the compressed air by the pressure of the remaining compressed air. In this case, since the water intake unit 65 is always in a position in contact with the lowermost surface of the tank 3 in the air chamber 3a, water can always be suitably drained without considering the rotational position of the tank 3.

  After all of the water and the remaining compressed air are discharged, the drain valve 66 is tightened, and the operation relating to the air hose reel 1 is completed.

  Next, an air hose reel according to a second embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 3 and 4, the air hose reel 101 according to the second embodiment is the same as the air hose reel 1 according to the first embodiment in the main configuration, and therefore only the differences are attached. The parts that are described and have the same configuration are added with reference numeral 100 and the description thereof is omitted.

  In the air hose reel 1 according to the first embodiment, only the high pressure discharge mechanism 5 is configured to be able to wind the high pressure hose 52 around the reel portion 3D. However, in the air hose reel 101 according to the second embodiment, The general pressure discharge mechanism 104 is also configured to be able to wind the hose around the reel portion.

  The general pressure discharge mechanism 106 mainly includes a general pressure reducing valve 141, a general pressure hose 142, and a general pressure female coupler 143. The general pressure pressure reducing valve 141 is provided on the outer periphery of the first shaft portion 131 and communicates with the general pressure air passage 131b. The compressed air stored in the air chamber 103a is supplied with a predetermined pressure (0.39). To about 0.98 MPa) to enable discharge. Further, the general pressure reducing valve 141 is configured to discharge the compressed air reduced in pressure to a general pressure hose connection passage 141 a formed in the first shaft portion 131.

  Further, a general pressure passage forming portion 142A is provided at a portion of the first shaft portion 131 where the general pressure hose connection passage 141a is formed. The general pressure passage forming portion 142A penetrates through the air chamber 103a and has one end connected to the general pressure hose connecting passage 141a and the other end connected to a discharge port (not shown) by the general pressure reel portion 103F. The compressed air in the hose communication passage 141a is configured to be discharged from a discharge port (not shown).

  The general pressure hose 142 is wound around the general pressure reel portion 103F, one end of which is connected to a discharge port (not shown) provided in the general pressure passage forming portion 142A, and the other end of the general pressure female coupler 143. Is provided.

  When using the air hose reel 101 configured as described above, the handle 132A is turned with the general pressure nailer 112 and the high pressure nailer 113 attached to the general pressure female coupler 143 and the high pressure female coupler 153, respectively. The general pressure hose 142 and the high pressure hose 152 wound around the tank 103 are extended to perform the work.

  At this time, in the general pressure nailer 112, the compressed air stored in the air chamber 103a flows into the general pressure pressure reducing valve 141 through the air passage 131a and the general pressure air passage 31b, and the general pressure pressure reducing valve 141 The general pressure hose 142 and the general pressure are discharged from a discharge port (not shown) that is reduced to a predetermined pressure (about 0.39 to 0.98 MPa), discharged into the general pressure hose connection passage 141a, and communicated with the general pressure passage formation portion 142A. Compressed air is sent to the general pressure nailer 112 through the female coupler 143.

Compressed air is sent to the high-pressure nailing machine 13 through the operation.

  Even when the air hose reel 101 is cleaned after the work is completed, the general pressure nail driver 112 and the high pressure nail driver 113 are attached to the general pressure female coupler 143 and the high pressure female coupler 153, respectively. The pressure hose 142 and the high pressure hose 152 can be wound up. Therefore, since both air hoses can be wound around the tank 103, the transportability of the air hose reel 101 with the air hose can be improved, and the time for moving the air hose reel 101 and preparing / connecting the pneumatic tool can be further increased. It can be shortened.

Even in such a configuration, the connection portion 63, the lead-out passage portion 64, and the water intake portion 65 are suspended from the central axis C by the weight, and therefore the water intake portion 65 provided at the end of the lead-out passage portion 64. The water in the tank 3 can be taken from. Moreover, by taking such a structure, since the weight which is a heavy article is suppressed from contact | abutting with the tank 3 inner surface, the contact sound which a weight contact | abuts to the tank 3 can be suppressed.

  In the first embodiment, only the high pressure hose can be wound around the reel portion 3D. However, the present invention is not limited to this, and a configuration in which only the general pressure hose can be wound may be adopted. Also. Moreover, since the high pressure pressure reducing valve and the low pressure pressure reducing valve for adjusting the pressure are integrated in the first shaft portion, the operability during pressure adjustment can be improved.
