Particularly, cargo transportation using an airplane is the fastest and safest cargo transportation that needs to cross the sea, such as an island or overseas, but it has a disadvantage that it requires a large cost for cargo transportation. On the island of the sea where there is no airplane takeoff and landing facility It is not applicable.

Therefore, the marine transportation method using the ship is mainly used on the island near the coast, and the marine transportation method using the ship takes a long time because of the slow moving speed of the ship.

In addition, the land transportation method using a vehicle such as a freight car is difficult to transport the cargo to the destination on time as the traffic volume of the road increases. In addition, the freight car itself causes a lot of pollution, It is a fact that there is a problem in use such as harm.

Furthermore, if the truck moves through the busy city center, the loss of transportation time is very large, and this time loss causes additional costs and causes the logistics cost to increase greatly. In addition, there are more restrictions in recent years, such as controlling the entry of freight cars into the city center in time or blocking the access of large-sized trucks to the city center.

Therefore, it is urgent to develop a new type of transportation system that can transport cargo quickly even in the city center, and is environmentally friendly and can reduce transportation costs.

As shown in the figure, the closed-loop-type transfer system according to the embodiment of the present invention is configured so that the capsule 170 can circulate and transfer the cargo by the wind pressure along the transfer pipeline 111 forming the closed circuit, It is possible to transport the cargo and reduce the transportation cost while being eco-friendly.

The closed circuit type transfer system according to the embodiment of the present invention includes a transfer pipe 111, a blowing pipe 112, a bypass pipe 113, a blower 120, a terminal 130, a slide valve 142, The pressure sensor 143, the differential pressure gauges 152a and 152b, the position sensor 151, and the operation of the blower 120, the slide valve 142 and the rotation valve 143 in conjunction with the sensors, Controller.

Hereinafter, a closed circuit type transfer system according to an embodiment of the present invention will be described in detail with reference to the respective components.

The transfer pipe 111 provides a circulation path for transferring the capsule 170 into the closed loop. A terminal 130, a rotation valve 143, a slide valve 142 and the like are installed in the middle of the transfer pipe 111 and a position sensor 151 for detecting the position of the capsule 170 to be transferred is installed . As shown in FIG. 5, at a point where the exhaust pipe 116 of the transfer pipe 111 is branched, the tubular body is maintained as it is, and a plurality of air discharge holes 111a for discharging air are formed . If this branching point is treated in such a manner as to form a wide opening and connect the exhaust pipe 116 as in the conventional manner, it may cause noise and vibration, including escape of the capsule 170 during transportation.

The blowing pipe 112 is branched at one point of the transfer pipe 111 and merged at another point of the transfer pipe 111 in a form of bypassing a part of the transfer pipe 111. A blower 120 is installed at an intermediate point of the blowing pipe 112 so as to blow air toward the joining point of the transferring pipe 111. Accordingly, the air blower 120 is divided into a joining point side and a branching point side. An air suction pipe 115 for sucking air in the blowing operation of the blower 120 is provided at a branch point side of the blowing pipe 112 and a rotation valve 143 for opening and closing the air suction pipe 115 is installed. A rotation valve 143 is provided at the branch point side of the blowing pipe 112 for interrupting the blowing pipe 112, which is provided in the air suction pipe 115.

The venturi pipe 112a is provided with a differential pressure gauges 152a and 152b for measuring the pressure of air blown from the blower 120. The differential pressure gauges 152a and 152b are connected to the venturi pipe 112a, Respectively. The differential pressure gauges 152a and 152b are respectively installed in the enlarged portion and the reduced portion of the venturi pipe 112a to measure the difference between the two. The controller calculates the wind pressure of the air discharged from the blower 120 .

The bypass pipe 113 bypasses the blower 120 installed in the middle of the vent pipe 112 and connects the vicinity of the branch point of the vent pipe 112 and the vicinity of the confluence point. Rotation valves 143 are provided at both ends of the bypass pipe 113. The bypass pipe 113 serves to selectively blow air to the transfer pipe 111 at a joining point and a branching point of the blowing pipe 112 to the transfer pipe at a position farther from the capsule . Since the supply of air is not smooth at the point where the capsule 170 is located in one transfer pipe 111 constituting the closed circuit, the capsule 170 is supplied with air at a long distance as far as possible at the position where the capsule 170 is located. Thereby generating a wind pressure for transport.

The blower 120 is installed in the middle of the blowing pipe 112 and blows the air for conveying the capsule 170 to the transfer pipe 111 via a merging point or a branching point of the blowing pipe 112. The rotational speed of the blower 120 is measured by the RPM meter and the wind pressure is measured by the above-mentioned differential pressure gauges 152a and 152b and transmitted to the controller. The controller is connected to the RPM meter and the differential pressure gauges 152a and 152b The blower 120 is controlled on the basis of the measured values to control the rotation speed and wind pressure of the discharge fan so that the delivery speed of the capsule 170 can ultimately be adjusted according to circumstances. Based on this, each valve is opened and closed as needed.

At least one of the terminals 130 is provided in the middle of the transfer pipe 111 to allow the capsule 170 to be drawn in or drawn out. The terminal 130 is formed in a shape not significantly different from the transfer pipe 111 and is connected to the transfer pipe 111 by a flange coupling so that the capsule 170 can pass therethrough. However, the terminal 130 is provided with an open door 131, which is openable and closable at the top, so that the capsule 170 can be drawn in and out. The terminal 130 is preferably made of a transparent material so that the capsule 170 located therein can be seen from the outside. The terminal 130 is normally installed at two or more points, unlike the drawing, in consideration of a point where the cargo is loaded or unloaded. Therefore, in the present invention, the transfer pipe 111 is not formed of a single long pipe but has a plurality of single pipes connected to each other, and the terminal 130 is selectively installed or easily removed at various points in the middle of the single pipes It is notable that it can be. Here, the single pipes are preferably unit pipelines having a predetermined length and differentiated shapes corresponding to each other between the straight line section, the curved section, and the entrance. The capsule 170 can be stopped by the method of discharging the air blown through the terminal 130 without the need for a separate magnetic force or a power source described below.

The rotation valve 143 is a valve that performs an opening and closing function by a rotating disk 143a and is installed at each point of the transfer pipe 111, the blowing pipe 112 and the bypass pipe 113. According to the drawing, rotation valves 143 are installed in the two exhaust pipes 116 branched from the transfer pipe 111, and opening and closing of the suction pipe 115 at the branching point side of the blowing pipe 112, And a rotation valve 143 is installed at both ends of the bypass pipe 113. The rotation valve 143 is provided at both ends of the bypass pipe 113, A rotation valve 143 is installed in the transfer pipe 111 near the rear end of the terminal 130 (a position immediately before the transferred capsule 110 reaches the terminal 130) The rotation valve 143 serves to guide the stopping of the capsule 170 being transferred by discharging the air blown to the terminal 130. According to this configuration, the capsule 170 is stopped without a magnetic force or a separate power source.

The slide valve 142 is installed in the middle of the transfer pipe 111 and serves to stably shut off the transfer of the capsule 170. The slide valve 142 is advantageously operated very quickly because the panel slidable by the pneumatic cylinder is configured to block across the transfer pipe 111 and operates using a pneumatic cylinder. Since the inner diameter of the transfer tube 111 is not changed, the capsule 170 can be prevented from being transported while the slide valve 142 is installed. The slide valve 142 is disposed at the distal end side of the terminal 130 so that the capsule 170 can stably stop without passing through the terminal 130. In addition, it can be usefully used when switching the supply path of air provided at a position just before the joining point of the blowing pipe 112 in the transfer pipe 111.

The differential pressure gauges 152a and 152b are respectively installed in an enlarged portion and a reduced portion of the venturi tube 112a as described above to measure the head difference between them. This allows the controller to control the transfer of the capsule 170 while calculating the air pressure of the air discharged from the blower 120 and adjusting it to a necessary level.

The position sensor 151 is installed on the transfer pipe 111 to sense the capsule 170. When the plurality of position sensors 151 are provided, the controller can grasp the position of the capsule 170 and control the rotation valve 143 and the slide valve 142 installed at the respective positions of the blower 120 according to the situation . For example, when the capsule 170 is sensed by the position sensor 151 installed at the previous position of the exhaust pipe 116 installed near the terminal 130, the controller operates the rotation valve 143 installed in the exhaust pipe 116, And the air blown through the opening 116 is discharged to the outside. The capsule 170 can be stopped at the terminal 130 as the pneumatic pressure for conveying the capsule 170 disappears.

Next, the configuration of the capsule 170 in the closed-loop type transfer system according to the embodiment of the present invention will be described.

FIG. 6 is a cross-sectional view of a capsule for explaining the configuration of a capsule in a closed-loop type delivery system according to an embodiment of the present invention, and FIG. 7 is a cross- Side view. 8A to 10 are photographs of a series of actual samples for explaining the configuration of the capsule in the closed-loop transfer system according to the embodiment of the present invention.

As shown in the figure, in the closed-loop transfer system according to the embodiment of the present invention, the capsule 170 includes a cylindrical capsule body 171 having a receiving space therein, A plurality of legs 174b provided at the distal end portion and the rear end portion of the capsule main body 171 and a pair of legs 174b attached to the distal end portion of the leg body 174b And a wheel 175 that is installed and contacts the inner wall of the transfer pipe 111.

A tip end portion and a rear end portion of the capsule main body 171 are provided with a rotating body 174a rotatably disposed on a central axis line of the rotating body 174c. The legs 174b are joined to the hinge 174d in a radially outwardly extending manner. The plurality of legs 174b are resiliently supported by a spring 176 disposed between the legs 174a and the rotating body 174a, and when the pressure is applied from the outside, the plurality of legs 174b are disengaged from each other, .

The lower portion of the capsule main body 171 is preferably designed to have a relatively low center of gravity. Thus, the capsule 170 can be prevented from unnecessarily rotating when it is conveyed from the conveying pipe 111, so that stable conveyance is possible. That is, a balance weight having a predetermined weight or more is additionally provided in the lower part of the capsule main body 171, thereby preventing rotation of the capsule 170 during transportation and stabilizing the transfer.

The capsule body 171 is provided with a magnet 173 so that the opening and closing door 172 can be kept closed. Thus, it is possible to prevent a problem that the opening / closing door 172 is unnecessarily opened even if the opening and closing door 172 is not tightened in most cases. 8A and 8B, the opening and closing door 172 is provided with a bolt insertion groove 172b for bolt fastening and a bolt hole 172c to be bolted to the capsule body 171 if necessary It is preferable to arrange for such an arrangement.

The blocking membrane 177 protrudes along the circumferential direction at the distal end and the rear end of the capsule body 171, respectively. The blocking membrane 177 itself is relatively thin and has a wide width in the form of a ring, thereby blocking the air blown out while filling the gap between the inner wall of the transfer pipe and the capsule body. This makes it possible to more efficiently use the air blown inside the transfer pipe, thereby improving the capacity of the capsule 170 to be transported. The material of the blocking membrane 177 is preferably a material having a low coefficient of friction and low wear resistance so as to minimize the problem of damage or wear when the pipe is rubbed against the inner wall of the transfer pipe.

The operation of the closed-loop-type transfer system according to the embodiment of the present invention will now be described with reference to FIGS. 11A to 11F and other drawings.

First, 11a is a state in which the capsule 170 is positioned at the terminal 130 before circulating along the transfer pipe 111. In this state, when the blower 120 is operated in a state where the bypass pipe 113 is blocked by the rotation valve 143, air is blown into the transfer pipe 111 through the joining point of the blowing pipe 112, The capsule 170 located at the terminal 130 starts to move and carry the cargo as shown in FIG. 11B.

Then, when the capsule 170 passes the confluence point of the ventilation pipe 112 through 11c and 11d, the operation is switched to the operation of blowing air to the conveyance pipe 111 through the confluence point of the ventilation pipe 112 And operates in such a manner that air is blown to the branch point side of the blowing pipe 112 through the bypass pipe 113.

The capsule 170 is continuously conveyed and passes through the position sensor 151 installed near the rear end of the terminal 130. The controller senses the capsule 170 in the position sensor 151 and then rotates the capsule 170 by the rotation valve 143, (116). Then, as the air carrying the capsules 170 is discharged through the exhaust pipe 116, the delivery speed of the capsules 170 is instantaneously reduced to stop at the terminal 130.

For the sake of convenience, the description of the transfer process of the capsule 170 under the condition that there is one terminal 130 for the convenience of explanation is made. However, at the actual site, when the terminal 130 is installed at a plurality of points requiring transportation of the cargo And an exhaust pipe 116 and a rotation valve 143 for stopping the capsule 170 are also provided to control each interval between the terminal 130 and the terminal 130.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is clear that the present invention can be suitably modified and applied in the same manner. Therefore, the above description does not limit the scope of the present invention, which is defined by the limitations of the following claims.
