Description

Detailed Description of the Invention

[0001]

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

As a physical distribution system for carrying various goods such as small parcels, ores, and garbage, a capsule / pipeline transfer system using a pipeline is drawing attention.
This system transfers a capsule containing a material to a destination by moving a capsule containing the material in a pipeline laid between a plurality of points such as a distribution center and a distribution center. As a conventional technology 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 run by an air flow of a large blower, and the materials loaded in the capsule are transported to a destination together with the capsule.

Further, a system in which a linear train is run in a tunnel and the loaded materials are automatically conveyed to a destination together with the linear train has been attracting attention.

[0004]

However, the conventional pneumatic-type capsule-type traveling system has the following drawbacks. Since the capsule travels at a high speed in the pipe, the sealing material is easily worn and the propulsive force of the capsule is easily reduced. At the curved pipe portion of the pipe, the sealability of the capsule is likely to deteriorate, so that it is necessary to increase the curvature of the pipe. (50D-100D, D is pipe diameter). In order to run the capsule, air must flow at high speed over the entire length of the pipeline, which causes a large pressure loss. In addition, when carrying a long distance, a booster station is required at regular intervals, and large-scale power and equipment are required. When firing the capsule body, the capsule cannot be fired continuously due to the large pressure drop. When increasing the speed of the capsule, it is necessary to increase the flow rate of air above the speed of the capsule, but pressure loss increases with the square of the flow rate, so it is not possible to increase the speed of the capsule to 10-20 m / sec or higher. It required a huge amount 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 drawbacks. Since it was necessary for humans to enter after constructing the tunnel and to lay a linear motor with a guide or a reaction plate, it was necessary to enlarge the tunnel.
When laying, the gap between the linear motor and the reaction plate is narrow, so accuracy is required and the construction period is extended.

Therefore, an object of the present invention is to provide a linear type capsule type traveling device for physical distribution, which is configured to convey materials at high speed and efficiently, and which comprises a linear tube and a linear capsule.
An object of the present invention is to provide a linear capsule having better running performance than ever before.

SUMMARY OF THE INVENTION The present invention is directed to a pipe made of a non-magnetic material and a plurality of annular magnetizing coils which are connected in series in the longitudinal direction of the pipe at a predetermined interval and whose polarities can be changed. From a linear tube consisting of, a capsule made of a non-magnetic material, traveling wheels attached to the front and rear of the capsule, and annular permanent magnets attached to the outer peripheral surfaces of the front and rear of the capsule. In a linear capsule of a linear type capsule type traveling device for physical distribution, the linear capsule does not overlap the magnetizing coil with the rear permanent magnet when the front permanent magnet overlaps the magnetizing coil. It is characterized in that the magnetic force of the magnetizing coil makes the force acting on the moving linear capsule uniform. Having. Further, in order to attach the permanent magnet in this way, the relationship between the distance between the front permanent magnet and the rear permanent magnet and the distance between the magnetizing coils satisfies the following equation (1). It is characterized by M = (4n + 0.5) L ─ (1) where M is the distance between the front permanent magnet and the rear permanent magnet, L is the distance between the magnetizing coils, and n is an integer. Also, a relationship between the distance between the magnetizing coils and the distance between the permanent magnets at the rear of the connected front capsules and the permanent magnets at the front of the rear capsules, in which two or more linear capsules are connected. Is characterized by satisfying the following expression (2). H = 2.5L-Equation (2), where H is the distance between the rear permanent magnet of the front capsule and the front permanent magnet of the rear capsule, and L is the distance between the magnetizing coils.

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 with the same axial center as the inner pipe 1a.
And a steel pipe 1c attached to the outer peripheral surface of the outer pipe 1b with 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 non-magnetic FRP having high wear resistance. 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 a non-magnetic material, plastic mixed with glass fibers. Magnetizing coil 3, sensor 10, section sensor 11, multiple power cables 12 and signal cable
13 is embedded in the thickness of the outer pipe 1b. Also,
An iron pipe may be attached instead of the steel pipe 1c of the outer pipe 1b. In this way, the strength of the linear tube 2 is maintained by attaching the steel pipe 1c or the iron pipe,
Further, the magnetic flux 23 becomes easy to pass.

The annular magnetizing coils 3 embedded in the wall thickness of the outer pipe 1b are continuously provided over the entire length of the linear tube 2 with a predetermined interval. The magnetizing coil 3 is
The magnetizing coil 3 is formed by winding the enameled wire in a number of layers, and the magnetizing coil 3 can be formed depending on the number of turns of the enameled wire, the number of steps, the winding width, and the interval.
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 position where the magnetizing coil 3 is located. Further, a section sensor 11 for switching the energization section is attached for each predetermined section (5 to 100 m). A plurality of power cables 12 for supplying power to the magnetizing coil 3, and a sensor 10,
A signal cable 13 for supplying power to the section sensor 11 is arranged in the longitudinal direction of the pipe 1.

The linear tube 2 thus constructed
Has a predetermined length, and the pipes 1 of the linear tubes 2 are connected to each other by welding joints when the pipe 1a is made of metal, and by socket joints when the pipe 1a is made of FRP. . The linear tube 2 of the present invention includes a magnetizing 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 process of connecting the pipes 1 to each other, and the number of processes is small. Further, the magnetizing 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
The capsule 6 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) are attached. In order to guide the magnetic flux 23 to the magnetizing coil 3 side, a material having a high magnetic permeability (iron, permalloy, etc.) may be attached to both sides or the inside of the permanent magnet 16.
The distance between the permanent magnet 16 and the magnetizing coil 3 is preferably as close as possible. In this case, the permanent magnet 16 may be divided and arranged at predetermined intervals in the circumferential direction. As a result, the opened gaps between the permanent magnets 16 act as air vents.

At the front and rear of the capsule 6, a plurality of wheels (five in the present embodiment) for running 17 are provided.
Are attached at equal intervals in the circumferential direction of the capsule 6, whereby the linear capsule 4 can travel in the linear tube 2. Further, the wheel 17 is pressed outward by the pressing means shown in FIGS. 6 and 7. 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 this 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 accommodating materials in the capsule 6, and is magnetically shielded by permalloy or the like. Alternatively, inside the capsule 6, a magnetically shielded inner capsule
19 may be mounted. And the capsule 6 is locked 22
It has an opening / closing door 18 with a hinge (for example, an electronic lock). Also, the inner capsule 19 can be opened and closed freely, and supplies are stored in this.

Since the driving force for running the linear capsule 4 works in the bend portion of the linear tube 2 in the same manner as in the straight portion, the linear capsule 4 has the shape of the pipe 1 as long as it has a shape defined by the following equation (1). Without touching the inner surface of
It can pass through bends with a small curvature.

[0016]

[Equation 1]

The section sensor 11 is provided for each predetermined section (5 to 100 m), and the section sensor 11 and the section power supply switching device are provided.
21 (eg thyristor), linear capsule 4
The electric current flows through the magnetizing coil 3 only in the section where is passing. In addition, since the permanent magnets 16 are attached to each of the connected linear capsules 4, the power does not increase even when two or more capsules 6 are connected by the connector 24.

Further, depending on the mounting position of the permanent magnet 16,
The thrust for making the linear capsule 4 travel can be made uniform or the thrust can be doubled. That is, in order to make the thrust of the linear capsule 4 uniform, the rear permanent magnet 16b overlaps the magnetizing coil 3 while the front permanent magnet 16a of the capsule 6 of the linear capsule 4 overlaps the magnetizing coil 3. It is necessary to set the mounting position of the permanent magnet 16 so that it does not occur. Therefore, 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 must satisfy the following expression (1). M = (4n + 0.5) L ─ (1) where M is the distance between the front permanent magnet and the rear permanent magnet, L is the distance between the magnetizing coils, and n is an 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 are increased. Set the relationship with the distance of to satisfy the following equation (2). H = 2.5L-Equation (2), where H is the distance between the rear permanent magnet of the front capsule and the front permanent magnet of the rear capsule, and L is the distance between the magnetizing coils.

However, it is preferable that the distance 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 operation principle of the linear capsule 4 is as follows. That is, the speed of the linear capsule 4 is obtained, the position is confirmed at the time when the sensor 10 on the front side of the magnetizing coil 3 detects it, and the permanent magnet 16 of the linear capsule 4 is at an appropriate position (it changes depending on the time constant of the magnetizing coil 3). At this point, the current of the magnetizing coil 3 is switched so that the electric current flows so that the adsorption is maximized at the center between the magnetizing coils 3 and 3. 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, linear capsule 4
Repel permanent magnet 16 of. By repeating this, the linear capsule 4 is continuously run.

For the speed control of the linear capsule 4, the speed of the capsule 6 is calculated from the switching time of the magnetizing 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 of each other, are installed in the collection station 7 to control the traveling of the linear capsule 4 in each section. As a result, the speed control of the linear capsule 4 is facilitated, and the departure interval of the linear capsule 4 can be easily set.

[0023]

Since the present invention is constructed as described above, the following industrially useful effects can be obtained. (1) The linear capsule 4 is mounted on the capsule 6 so that the rear permanent magnet 16b does not overlap the magnetizing coil 3 when the front permanent magnet 16a overlaps the magnetizing coil 3, so that the linear capsule 4 runs. The thrust force for making the linear capsule 4 uniform is obtained, and the stable running performance of the linear capsule 4 is obtained. (2) By using the non-contact type linear capsule type traveling device, the structure of the linear capsule 4 is simplified and only the wheels 17 are in contact with the inner peripheral surface of the inner pipe 1a of the linear tube 2, The maintenance is easy, the speed can be increased, and the linear capsule 4 can be structurally passed without the need to process the propulsive force due to the wear of the seal material and to maintain the sealing property at the bend part. As long as possible, the curvature of the linear tube 2 can be reduced. (3) The linear capsule 4 is moved directly by electricity, which is efficient, and long-distance electric transmission can be easily performed, which enables long-distance traveling. (4) Division into sections, section sensor 11 and section power supply switching device 21
Since the current is supplied only to a very small section of the portion where the linear capsule 4 passes, the current consumption is small and it is economical. (5) Since the position and speed control of the linear capsule 4 can be performed, loading and unloading can be performed quickly and accurately. (6) By using the pipe 1, the device itself has both a guide and protection, so that the equipment can be simplified. (7) Since the connection of 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 windings, the number of steps, the winding width and the spacing of the enameled wire of the magnetizing coil 3 attached to the pipe 1, and the linear capsule 4 can also be linear depending on the shape of the permanent magnet 16. The thrust of the capsule 4 can be determined. (9) By attaching the permanent magnets 16 to the linear capsules 4, 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 and Enables increased transport volume. (10) By reversing the magnetizing method of the magnetizing coil, the linear capsule 4 can travel in the opposite direction, and therefore the linear capsule 4 can travel back and forth, so that no facility for reciprocating is required. (11) Linear tube 2, magnetizing coil 13, power cable
By making the signal cable 12, 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 welding (metal) or joint bonding (FRP). Therefore, since the linear tube 4 can be produced at the factory and then assembled on-site at the laying site, there is almost no need to make adjustments in the work process, and construction can be performed with the same ease as with conventional pipeline laying. Can be shortened and downsized.
