DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a linear capsule for a distribution-type linear capsule traveling apparatus for efficiently transporting materials at high speed by using pipelines above and below ground.

2. Description of the Related Art As a distribution system for transporting various goods such as parcels, ores, and garbage, a capsule / pipeline transport system using a pipeline has attracted attention.
In this system, a capsule containing goods is transported through a pipeline laid between a plurality of points, such as between a distribution center and a distribution center, to convey goods to a destination. As a prior art of such a capsule pipeline transportation system, a pneumatic capsule type traveling system has already been developed. In this system, a capsule with a seal in a pipe is caused to travel by an airflow of a large blower, and a material loaded on the capsule is transported together with the capsule to a destination.

[0003] A system in which a linear train travels in a tunnel and the loaded goods are automatically transported together with the linear train to a destination has also attracted attention.

[0004]

However, the conventional pneumatic capsule-type traveling system has the following disadvantages. Since the capsule is run at a high speed in the pipe, the seal material is easily worn, and the propulsive force of the capsule is easily reduced. In the curved pipe portion of the pipe, the sealing property of the capsule is easily deteriorated, so that it is necessary to increase the curvature of the pipe. (50D ~ 100D, D is pipe diameter). Since the air must flow at high speed over the entire length of the pipeline in order to run the capsule, a large pressure loss occurs. Moreover, when transporting over long distances, a booster station is required at regular intervals, and large-scale power and equipment are required. When firing a capsule body, the capsule cannot be fired continuously because of the large pressure drop. When increasing the speed of the capsule, it is necessary to increase the flow rate of the air beyond the speed of the capsule, but since the pressure loss increases with the square of the flow rate, it is not possible to increase the speed of the capsule to 10-20 m / sec or more. Required a great deal of energy and had difficulties. Blower stations were needed at both ends of the pipeline to return the capsules.

On the other hand, the linear train has the following disadvantages. Since a human had to enter the tunnel after it was built, a linear motor with a guide or a reaction plate had to be laid, so that the tunnel had to be enlarged.
When laying, the clearance between the linear motor and the reaction plate is narrow, so accuracy is required and the construction period is lengthened.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a distribution type linear capsule traveling device comprising a linear tube and a linear capsule for efficiently transporting materials at high speed.
An object of the present invention is to provide a linear capsule having better running performance than before.

Section sensor 11 for section switching and multiple power cables 12
And a signal cable 13. The pipe 1 of the linear tube 2 includes an inner pipe 1a and an outer pipe 1b provided on the outer peripheral surface of the inner pipe 1a on the same axis as the inner pipe 1a.
And a steel pipe 1c attached to the outer peripheral surface of the outer pipe 1b on the same axis as the outer pipe 1b. In addition, FIG.
The steel pipe 1c is not shown. The inner pipe 1a is made of a non-magnetic, highly wear-resistant FRP. As the material of the inner pipe 1a, SUS304 stainless steel, aluminum or the like is used in addition to the above-mentioned FRP. Outer pipe
1b is made of non-magnetic plastic mixed with glass fiber. Magnetizing coil 3, sensor 10, section sensor 11, multiple power cables 12, and signal cables
13 is embedded in the thickness of the outer pipe 1b. Also,
Instead of the steel pipe 1c of the outer pipe 1b, an iron pipe may be attached. Thus, by attaching the steel pipe 1c or the iron pipe, the strength of the linear tube 2 is maintained,
Further, the magnetic flux 23 passes easily.

The annular magnetized coils 3 embedded in the thickness of the outer pipe 1b are continuously provided at predetermined intervals over the entire length of the linear tube 2. The magnetizing coil 3
It is formed by winding an enamel wire several times, and depending on the number of turns, the number of steps, the winding width and the interval of the enamel wire, the magnetization coil 3 is formed.
Are different in the force acting on the permanent magnet 16 of the linear capsule 4. A sensor 10 (proximity switch, magnetic sensor, etc.) for detecting the linear capsule 4 is attached to the magnetizing coil 3 at each location where the magnetizing coil 3 is located. Further, a section sensor 11 for switching the current-carrying section is provided for each predetermined section (5 to 100 m). A plurality of power cables 12 for supplying power to the magnetizing coil 3, and sensors 10,
A signal cable 13 for feeding power to the section sensor 11 is provided in the longitudinal direction of the pipe 1.

The linear tube 2 constructed as described above
Has a predetermined length, and the connection of the linear tube 2 to the pipes 1 is performed by bonding with a welded joint when the pipe 1a is made of metal, and by bonding with a socket joint when the pipe 1a is made of FRP. . The linear tube 2 of the present invention includes a magnetized coil 3, a sensor 10, a section sensor 11, a plurality of power cables 12, and a signal cable.
Since 13 is embedded in the thickness of the outer pipe 1b, the laying work is mainly a work for connecting the pipes 1 to each other, and the number of steps is small. Further, the magnetized coil 3, the sensor 10, the section sensor 11, the plurality of power cables 12, and the signal cable 13 are not exposed.

The linear capsule 4 comprises a capsule 6, a permanent magnet 16, and wheels 17. Linear capsule 4
Is made of non-magnetic SUS 304 stainless steel. As the material of the capsule 6, aluminum or the like can be used in addition to SUS 304 stainless steel. An annular permanent magnet is provided at the front and rear of the capsule 6.
16 (16a, 16b) is attached. In order to guide the magnetic flux 23 to the magnetization coil 3 side, a material having high magnetic permeability (iron, permalloy, or the like) may be attached to both sides or inside of the permanent magnet 16.
It is desirable that the distance between the permanent magnet 16 and the magnetizing coil 3 be as close as possible. In this case, the permanent magnets 16 may be divided and arranged at predetermined intervals in the circumferential direction. Thereby, the gap between the opened permanent magnets 16 acts as an air vent.

A plurality of (in this embodiment, five) wheels 17 for traveling are provided at the front and rear of the capsule 6.
Are attached at equal intervals in the circumferential direction of the capsule 6, whereby the linear capsule 4 can run inside the linear tube 2. The wheels 17 are pressed outward by pressing means shown in FIGS. 6 and 7, 17 is a wheel, 30 is a bearing, 31 is a shaft, 32 is a frame, and 33 is a spring. In the present embodiment, two linear capsules 4 are connected, and a permanent magnet 16 is attached to each of the connected linear capsules 4.

The linear capsule 4 has a space for storing materials in the capsule 6, and is magnetically shielded by permalloy or the like. Alternatively, an inner capsule magnetically shielded in the capsule 6
19 may be installed. And the capsule 6 is locked 22
It has an attached (for example, an electronic lock) hinged open / close door 18. The inner capsule 19 is also openable and closable, and supplies are stored therein.

The propulsive force for running the linear capsule 4 acts on the bend portion of the linear tube 2 in the same manner as the linear portion. Without touching the inner peripheral surface of
It can pass through a bend with a small curvature.

[0016]

(Equation 1)

The section sensor 11 is provided for each predetermined section (5 to 100 m), and is connected to the section sensor 11 and the section power supply switching device.
21 (for example, thyristor)
The current flows through the magnetizing coil 3 only in the section where. Further, since the permanent magnet 16 is attached to each of the connected linear capsules 4, there is no increase in power even when two or more capsules 6 are connected by the connecting device 24.

Further, depending on the mounting position of the permanent magnet 16,
The thrust for running the linear capsule 4 can be made uniform or the thrust can be doubled. That is, in order to make the thrust of the linear capsule 4 uniform, when the permanent magnet 16a at the front of the capsule 6 of the linear capsule 4 overlaps the magnetizing coil 3, the permanent magnet 16b at the rear overlaps the magnetizing coil 3. It is necessary to set the mounting position of the permanent magnet 16 so as not to be lost. For this purpose, it is necessary that the relationship between the distance between the front permanent magnet 16a and the rear permanent magnet 16b and the distance between the magnetizing coils 3 satisfy the following expression (1). M = (4n + 0.5) L─ (1) where M: distance between the front permanent magnet and the rear permanent magnet, L: distance between the magnetized coils, n: integer.

Further, when two capsules 6 are connected, the distance between the rear permanent magnet 16b of the front capsule 6a and the front permanent magnet 16a of the rear capsule 6b, and the distance between the magnetizing coils 3 Is set so that the relationship with the distance satisfies the following equation (2). H = 2.5L─ (2) where H: distance between the permanent magnet at the rear of the front capsule and the permanent magnet at the front of the rear capsule, L: distance between the magnetized coils.

However, it is preferable that the interval between the magnetizing coils 3 is appropriately adjusted so as to be narrow at the inclined portion and the vertical portion of the linear tube 2.

[0021]

The principle of operation of the linear capsule 4 is as follows. That is, the speed of the linear capsule 4 is obtained, and the position is confirmed when the sensor 10 on the front side of the magnetizing coil 3 detects the position. The permanent magnet 16 of the linear capsule 4 is positioned at an appropriate position (changes according to the time constant of the magnetizing coil 3). When the current comes, the current of the magnetizing coil 3 is switched, and the current is caused to flow at the center between the magnetizing coils 3 and 3 so as to maximize the attraction. Next, when the next sensor 10 detects the linear capsule 4, the current is switched so that the repulsion between the magnetizing coil 3 and the permanent magnet 16 is maximized at the center between the magnetizing coils 3 and 3. Thus, the linear capsule 4
Repels the permanent magnet 16 of By repeating this, the linear capsule 4 is continuously driven.

The speed of the linear capsule 4 is controlled by calculating the speed of the capsule 6 from the switching time of the magnetized coil 3.
Based on this, the current is controlled to control the speed of the linear capsule 4. The control power supplies 25a and 25b, which are divided into several sections and are independent from each other, are installed in the accumulation place 7, and the travel of the linear capsule 4 in each section is controlled. Thereby, the speed control of the linear capsule 4 becomes easy, and the departure interval of the linear capsule 4 can be easily set.

[0023]

Since the present invention is configured as described above, the following industrially useful effects can be obtained. (1) The linear capsule 4 runs on the capsule 6 by attaching the rear permanent magnet 16b to the capsule 6 so that the front permanent magnet 16a does not overlap the magnetizing coil 3 when the front permanent magnet 16a overlaps the magnetizing coil 3. The thrust for making the linear capsule 4 uniform is obtained, and stable running performance of the linear capsule 4 is obtained. (2) The structure of the linear capsule 4 is simplified by using the non-contact type linear capsule type traveling device, and only the wheel 17 is in contact with the inner peripheral surface of the inner pipe 1a of the linear tube 2, Maintenance is easy, high-speed operation is possible, and there is no need to reduce the propulsion force due to abrasion of the sealing material and to perform processing for maintaining the sealing property at the bend portion, so that the linear capsule 4 can pass through structurally. As long as possible, the curvature of the linear tube 2 can be reduced. (3) The linear capsule 4 is moved directly by electricity to move the linear capsule 4 efficiently, and long-distance transmission can be easily performed, thereby enabling long-distance traveling. (4) Section division, section sensor 11 and section power switching device 21
As a result, the current is supplied only to a very small section of the portion through which the linear capsule 4 passes, so that current consumption is small and economical. (5) Since the position detection and speed control of the linear capsule 4 can be performed, unloading can be performed quickly and accurately. (6) By using the pipe 1, the equipment itself can serve as both a guide and protection, so that the equipment can be simplified. (7) Since the connection of the linear capsules 4 and the departure interval can be controlled, mass transportation can be performed efficiently. (8) The force acting on the permanent magnet 16 can be determined by the number of turns, the number of steps, the winding width, and the interval of the enameled wire of the magnetized coil 3 attached to the pipe 1, and also linearly by the shape of the permanent magnet 16 of the linear capsule 4. The thrust of the capsule 4 can be determined. (9) By attaching the permanent magnets 16 to the linear capsules 4 respectively, the propulsive force of the linear capsules 4 can be increased without increasing the electric power, the linear capsules 4 can be connected, and the traveling of the inclined portion and the vertical portion can be performed. Enables increased transport volume. (10) By reversing the magnetizing method of the magnetizing coil, the linear capsule 4 can travel in the opposite direction, so that the linear capsule 4 can reciprocate, so that no reciprocating equipment is required. (11) Connect the linear tube 2 with the magnetized coil 13 and the power cable
By integrating the signal cable 13, the sensor 10, and the section sensor 11 into an integral structure, the pipes 1 can be connected to each other by bonding (metal) by welding or bonding of joints (FRP). Therefore, since the linear tube 4 can be produced at the factory and assembled on site at the installation site, there is almost no need for adjustment in the work process, and the construction can be performed with the same simplicity as the conventional pipeline laying. Can be shortened and downsized.
