Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a compressed air distribution device that sequentially distributes compressed air fed through a system of supply pipes to a plurality of systems of supply pipes and discharges the compressed air. .

A pine surge device, etc. that supplies compressed air to a pine tress for pine surge made up of a plurality of metal bags in parallel to inflate and deflate each bag in sequence, causing a rhythmic undulating motion in the pine surge to perform pressure footing. is provided with a distribution valve arrangement for distributing compressed air. This distribution valve device distributes all the compressed air sent from a compressed air source such as a compressor through one system of supply pipes in a fixed order, and passes the compressed air through all the supply pipes of individual transfers to the Mattress. This device has the function of sequentially feeding the material into each of the constituent bags, but in the case of a pine surge device such as the one described above that generates full wave motion in a pine tress made up of multiple bags, it is necessary to create smoothness in the wave motion caused by the bags. In this case, it is also necessary to have a function that can arbitrarily control the period of the wave.Furthermore, since conventional distribution valve devices of this type are built into the case together with the compressor, the length of the compressor must be reduced. In response to the above-mentioned demands, the present invention aims to create smooth wave motion in the map page mat.
This system distributes the compressed air that is not sent through the supply pipes of the engineering system to multiple systems in a fixed order, and allows the inflation time and period of wave motion of each bag to be controlled arbitrarily. Embodiments of the present invention will be described with reference to all the drawings.

FIG. 1 is an explanatory diagram of the system applied to the fully pneumatic pine-length distribution valve device of the present invention, FIG. cutaway perspective view,
FIG. 4 is a developed view of the rotary valve body of the distribution valve device, and FIGS. 5 and 6 are developed views showing the other side of the rotary body.

As shown in FIG. 1, the distribution valve device 10 of the present invention is configured such that compressed air is supplied from a pneumatic source 1 such as a compressor tube through a single feed pipe 2, and the air is supplied to multiple systems via the device 10 of the present invention. tube 3,
The distribution valve device 10 is fixed to the housing 11 as shown in FIGS. It consists of a rotating body 13 that is rotatably housed inside a cylinder 12 and a motor 14 that rotates the rotating body 13.

The rotating body 13 has 15 shaft holes extending along the axis, and extending outward from the shaft hole 15 are a guide hole 16 and a plurality of openings (channels) 17, 17, . . . is drilled. The openings 17, 17... are arranged at equal intervals in the axial direction,
In addition, exhaust grooves 19, 19, . ...The exhaust grooves 19 are fully formed, and the exhaust grooves 19 communicate with each other through the communication grooves 20.

On the other hand, 21 air inlets are provided at appropriate positions of the cylinder 12 in a portion facing the endless groove 18 provided in the rotating body 13, and are connected to a socket 22 attached to the housing 11 via a connecting pipe 23. . Furthermore, the cylinder 12 is provided with a plurality of air supply and discharge ports 24, 24, . In addition, all exhaust holes 25 are provided in a portion of the cylinder 120 corresponding to at least one exhaust groove 19 of the rotating body 13. In this embodiment, there are two exhaust holes 25.
However, the exhaust groove 19 provided in the rotating body 13
．． 19 are connected through separate communication grooves 20 and 20 on the left and right, respectively, so each exhaust hole 25 is independent. It is set up. Therefore, as long as all the exhaust grooves 19 communicate with each other, only one exhaust hole is required.
, 24 . . . are connected to a multi-ronket 27 fixed to the housing 11 by the same number of connecting pipes 26 , 26 .

Next, to explain the operation of the above embodiment, in FIG. A feed pipe 3, 3, . . . is connected to each of the plurality of bags 4', 4', .
. . are connected in the predetermined order and driven by the air pressure source 1 and the motor 147 of the distribution valve device 10. As a result, when the compressed air generated by the air pressure source 1 is supplied to the distribution valve device 10, it flows into the air introduction endless groove 18 of the rotating body 13 from the introduction port 21 of the cylinder 12. Endless groove 1
The compressed air flowing into the cylinder 8 flows from the guide hole 16 to the shaft hole 15, and at this time, the opening of any one of the flow paths 17 is connected to the cylinder 1.
2, the compressed air flows from the flow path 17 to the discharge port 24, and the compressed air is supplied from the corresponding feed pipe 3 to the bag body 4'. The bag body 4' into which air has been introduced expands. For example, in FIG. 4, the passage 17 is aligned with the outlet 24, so that the bag corresponding to the stiffness expands. The rotating body 13 is the motor 14
When the flow path 17 is further rotated and the flow path 17 is separated by 24 discharge ports, the supply path to the bag is closed, the expansion of the bag is stopped, and the expanded state is maintained. As the rotation of the rotating body 13 progresses, the flow path 17 enters the region of the discharge groove 19, and the compressed air that was not being supplied to the bag body flows back into the discharge groove 19 and flows out through the 25 discharge holes of the cylinder 12 to the outside. do. The bag body 4 contracts due to stiffness. Since each flow path 17 opens in a spiral shape toward the surface of the rotating body 130, the discharge and backflow of compressed air from the supply air discharge port 24 are sequentially caused by the discharge ports 24 adjacent to each other. , and the corresponding wave-like expansion and contraction movements of the bag body? Do it repeatedly. Mo, I! 14 revolutions? The slower the inflation time, the longer the inflation duration can be maintained. This action causes the pine tree to move in a wave motion over the entire period, and the speed of the wave motion can be controlled by a remote controller 5 shown in FIG.

In the figure, reference numeral 6 denotes a power switch for the distribution valve device 10, and the distribution valve device 10 can be driven or stopped by the power switch 6 or any part of the controller 5. 7 is a power line, which is led from the air pressure source 2 here. As shown in the figure, seven power supply wires may be wired around the feed pipe 2, but of course they may be wired independently, or the power wires built into the feed pipe 2 may be used. good.

Furthermore, the air supply outlet 24 is connected to the cylinder 1 as shown in FIG.
2 may be arranged in a spiral pattern 7, thereby shortening the time interval during which the discharge of compressed air transits to adjacent discharge ports 24, and making the wave motion in the mat relatively smooth.

In the embodiment shown in FIG. 6, the opening of the flow path 17 is expanded in the circumferential direction and is formed so as to partially overlap with the opening of the flow path that overlaps in the axial direction.

According to this configuration, since adjacent flow paths coincide with adjacent discharge ports 24 at the same time, the expansion movement of the mat becomes smoother.

In this way, the bag inflation movement can be arbitrarily set depending on the positions and sizes of the discharge port 24 and the flow path 17, and the design can be changed as appropriate depending on the application and specifications.

As described above, the distribution valve device of the present invention is provided inside a rotary body cylinder that is rotated by a motor drive, and has an air introduction endless groove on the outer peripheral surface of the rotary body, and an opening (flow path) communicating with this endless groove. In addition to forming the sound, the cylinder/cylinder is provided with a discharge port that sequentially communicates with the openings of the rotating body and an inlet that constantly communicates with the endless groove, and further includes discharge holes that are on the same circumference as the individual openings of the flow path. Since exhaust grooves are provided that communicate with the l
By distributing the compressed air sent through the system's feed pipe to multiple systems, it is possible to smoothly generate a wave-like expansion movement in the pine cage mat, and also to reduce the expansion and contraction time of each bag and the wave movement. The period can be arbitrarily controlled, and it is extremely versatile and has high utility value as a distribution valve device.
