Abstract

PURPOSE:To restart a capsule by a method wherein every one of several electromagnets is driven according to the speed for the purpose of power save during steady traveling of the capsule and all electromagnets in a predetermined section are driven only when the capsule stops abnormally. CONSTITUTION:During stead traveling of a capsule 1, every one of several coils of electromagnets is driven. All electromagnet coils 5 in the section where the capsule 1 is located are driven upon abnormal stoppage of the capsule 1. Further, traveling speed of the capsule 1 may be increased by driving all electromagnet coils during travel of the capsule 1.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for restarting a capsule in a linear capsule-type traveling device for transporting materials efficiently and at high speed using a conduit. .

[Conventional technology]

Capsule pipeline transportation systems that utilize pipelines made up of pipes have traditionally been attracting attention as a logistics system for transporting various materials such as parcels and garbage. This system transports goods to their destination by running capsules through pipelines laid between multiple points, such as between a distribution center and a distribution center.

As a conventional technology for such a capsule pipeline transportation system, a pneumatic capsule traveling system has already been developed. This system uses airflow from a large blower to move a capsule inside a pipe, and transports the materials loaded in the capsule to the destination together with the capsule.

[Problem to be solved by the invention]

However, the conventional pneumatic capsule type traveling system has the following drawbacks.

■ Because the capsule is run at high speed inside the pipe, the sealing material tends to wear out and the driving force of the capsule tends to drop.

■ In the curved portion of the pipe, the sealing performance of the capsule is likely to deteriorate, so the curvature of the pipe must be increased, which is disadvantageous in terms of pipeline design.

■ At pipe branching sections, complex switching drive equipment must be installed to maintain air pressure.

■ To move the capsule, air must flow at high speed along the entire length of the pipeline, resulting in a large pressure drop. Moreover, when transporting over long distances, a booster is required, and a large blower is also required, requiring large-scale moving machines and equipment.

■ Capsules cannot be fired continuously because a large pressure trop is generated when the capsule body is fired.

■ When increasing the capsule speed, it is necessary to increase the flow speed above the set capsule speed, so the pressure loss increases as the square of the flow speed. Therefore, the speed of the capsule is 2
It is difficult to achieve a high speed of 0 to 30 m/sec or more.

■ Blower stations are required at both ends of the pipeline to return the capsules.

In this way, the conventional pneumatic capsule type transport system has the drawbacks mentioned above, so it is possible to transport goods at higher speeds.
There is a strong desire to develop a capsule pipeline transportation system that can transport materials efficiently and has lower construction costs such as equipment costs.

In order to solve the above-mentioned problems, the inventors developed a linear capsule-type traveling device that can efficiently transport materials at high speed and is inexpensive to construct. This led to the invention of a restart method.

Therefore, an object of the present invention is to provide a method for restarting a capsule of a linear capsule type traveling device.

[Means to solve the problem]

The present invention includes a pipe made of a non-magnetic material, a capsule made of a non-magnetic material that can freely travel within the pipe via wheels that contact the inner peripheral surface of the pipe, and a capsule that is attached to the outer peripheral surface of the capsule. A permanent magnet of the capsule and an oval coil are wound on the outer peripheral surface of the pipe at intervals over the entire length of the pipe so that the magnetic field formed by the permanent magnet of the capsule and the oval coil is always influenced. an electromagnet whose polarity can be changed; a polarity conversion mechanism for changing the polarity of the electromagnet; and a sensor for detecting the position of the capsule, for example, a magnetic sensor for detecting the position of the capsule. The sensor is a linear capsule-type traveling device that moves the capsule by aligning the electromagnet with the position of the capsule and switching the current of the coil to repeatedly attract and repel the permanent magnet. During steady running, the electromagnets are driven every few pieces according to the speed in order to save power, and only when the capsule stops due to an abnormality, all the electromagnets in a predetermined section where the capsule is located are driven to move the capsule. It is characterized by its ability to move.

Next, the present invention will be explained with reference to the drawings. FIG. 3 is a side view showing the linear capsule type traveling device, and FIG. 4 is a sectional view taken along line A--A in FIG. 3.

As shown in FIGS. 3 and 4, a capsule 1 with a circular cross section is inserted into a pipe 2 with a circular cross section.

The capsule 1 is made of a non-magnetic material, such as SUS 304 or aluminum.

Permanent magnets 4 are annularly wound around the upstream and downstream ends of the capsule 1 in the circumferential direction of the capsule 1 .

For air removal, the permanent magnets 4 may be arranged at predetermined intervals in the circumferential direction. A plurality of wheels 3 (for example, about 10 wheels) are provided at predetermined intervals in the circumferential direction of the capsule 1 on the upstream and downstream sides of the capsule 1, respectively.

The capsule 1 is freely movable within the pipe 2 via wheels 3 that are in contact with the inner peripheral surface of the pipe 2. Although not shown, the capsule I has a single-hinged opening/closing door with a lock, and a magnetically shielded inner capsule is mounted inside this door. This inner capsule can also be opened and closed, and cargo can be loaded inside.

Pipe 2 is SUS 304. Aluminum or FRP
Non-magnetic tubes such as those made of aluminum can be used. pipe 2
An electromagnet consisting of an oval coil 5 is wound around the outer peripheral surface of the coil 5 in an annular manner. The coil 5 has permanent magnets 4 of capsules 1 attached at predetermined intervals over the entire length of the pipe 2 where the magnetic field of the oval coil 5 exerts an influence.

Note that a section sensor (not shown) is provided for each predetermined section (50 to 100 m), and no current flows through the coil 5 in sections where the capsule 1 does not pass.

In FIG. 2(a) and FIG. 2(b), ◯ marks indicate driving, and X marks indicate stopping. When the capsule 1 is running normally, the electromagnetic coils 5 are driven every few times as shown in FIG. 2(a), but some abnormality occurs. When capsule 1 has stopped, Fig. 2 (b
), all the electromagnetic coils 5 in the section where the capsule J is located are driven. It is also possible to increase the traveling speed of the capsule 1 by driving all the electromagnetic coils while the capsule 1 is traveling.

〔Effect of the invention〕

Since this invention is configured as described above, it produces the following useful effects.

■ By using a non-contact glue near motor,
The only part of contact between the pipe and capsule is the wheel, making it possible to achieve higher speeds.

■ It is efficient because the capsule is driven directly using electricity, and electricity can be easily supplied even over long distances, making it easy to transport long distances.

■ Since current is passed only to the section where the capsule is running, current consumption is low and economical.

■ It is easy to automate because it can detect the position of the capsule and control its speed.

■During steady running, the electromagnetic coils are driven every few, so current consumption is low and economical.

- When the capsule stops, it can be restarted simply by driving the electromagnetic coil, and troubles such as accidents caused by the capsule stopping can be prevented without using auxiliary means such as a rescue vehicle.
