Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a capsule restarting method in a linear capsule-type traveling device for efficiently transporting goods at high speed using a pipeline. .

[Conventional technology]

As a logistics system for transporting various goods such as parcels, garbage, etc.
Capsule / pipeline transportation systems using garbage are attracting attention. This system transports goods to a destination by running capsules in a pipeline laid between a plurality of points, such as between a distribution center and a distribution center.

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 in a pipe is caused to travel by an airflow from a large blower, and the material loaded on the capsule is transported to a destination together with the capsule.

[Problems to be solved by the invention]

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

Since the capsule runs at high speed in the pipe, the seal material is easily worn, and the driving 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, which is disadvantageous in designing the pipeline.

At the branch portion of the pipe, a switching driving device having a complicated structure must be provided because it is necessary to maintain air pressure.

In order to run the capsule, air must flow at high speed over the entire length of the pipeline, resulting in a large pressure loss. In addition, a large-scale power and equipment are required, such as a booster when transporting a long distance and a large blower.

The capsule cannot be fired continuously because of the large pressure drop when firing the capsule body.

To increase the speed of the capsule, it is necessary to increase the flow rate to a speed higher than the set capsule speed, and the pressure loss increases with the square of the flow rate. Therefore, the speed of the capsule is 20
It is difficult to increase the speed to 30 m / sec or more.

To return the capsule, blower stations are needed at both ends of the pipeline.

As described above, the conventional pneumatic capsule-type traveling system has the above-described drawbacks, so that materials can be transported at higher speed and more efficiently, and the construction cost such as equipment cost is lower. The development of capsule and pipeline transportation systems is strongly desired.

The present inventors have developed a linear capsule-type traveling device that can efficiently convey materials at high speed and have a low construction cost in order to solve the above-described problems.
The invention of a method of restarting when the capsule has stopped has been reached.

Accordingly, an object of the present invention is to provide a capsule restart method for a linear capsule traveling device.

[Means for solving the problem]

The present invention provides a pipe made of a non-magnetic material, a capsule that can run in the pipe through a wheel that comes into contact with the inner peripheral surface of the pipe, a capsule, and a permanent magnet attached to the outer peripheral surface of the capsule. Consisting of a circular coil, the outer surface of the pipe is wound over the entire length of the pipe at intervals that always affect the magnetic field formed by the permanent magnet of the capsule and the circular coil. A convertible electromagnet, a polarity conversion mechanism for converting 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 comprising: A linear capsule type running in which the current of the coil is switched by aligning an electromagnet with the position of the capsule, and the capsule is run by repeating attraction and repulsion to the permanent magnet. In the device, during steady running of the capsule, the electromagnets are driven at intervals of several in accordance with the speed for power saving, and only when the capsule is stopped due to an abnormality or the like, all of the electromagnets in a predetermined section where the capsule is located. Is driven to move the capsule.

Next, the present invention will be described with reference to the drawings. Third
FIG. 4 is a side view showing the linear capsule-type traveling device, and FIG. 4 is a sectional view taken along line AA of FIG.

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

The capsule 1 is made of a capsule body made of a non-magnetic material, for example, SUS304 or aluminum. At the upstream end and the downstream end of the capsule 1, a permanent magnet 4 is annularly mounted in the circumferential direction of the capsule 1. For air bleeding, the permanent magnets 4 may be disposed at predetermined intervals in the circumferential direction. Capsule 1
On the upstream side and the downstream side, a plurality (for example, about 10) of wheels 3 are provided at predetermined intervals in the circumferential direction of the capsule 1. The capsule 1 is able to travel inside the pipe 2 via wheels 3 that come into contact with the inner peripheral surface of the pipe 2. Although not shown, the capsule 1 has a lockable one hinged opening / closing door, in which an inner capsule magnetically shielded is mounted. The inner capsule can also be freely opened and closed, and luggage is loaded therein.

As the pipe 2, a non-magnetic pipe made of SUS304, aluminum, FRP or the like can be used. On the outer peripheral surface of the pipe 2, an electromagnet including a circular coil 5 is wound in an annular shape. The coil 5 is the capsule 1 over the entire length of the pipe 2.
Of permanent magnets 4 are attached at predetermined intervals that are affected by the magnetic field of the circular coil 5.

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

[Action]

Next, the capsule restart method of the present invention will be described. FIG. 1 is an explanatory view showing a mounting position of an electromagnet. In FIG. 1, 1 is a magnet 4 and an electromagnet (coil 5).
And n indicates the number of connections when the capsule 1 is connected in plural. By mounting the electromagnet (coil 5) at a distance of 2 ln or less, the electromagnet and the magnet are always connected by a magnetic field. FIG. 2 (a) shows a driving state of the electromagnet coil 5 for causing the capsule 1 to run in a steady state, and FIG. 2 (b) shows a driving state of the electromagnet coil 5 when the stopped capsule 1 is restarted. Show. In FIGS. 2 (a) and 2 (b), the mark 駆 動 indicates drive, and the mark x indicates stop.
During the steady running of the capsule 1, the coils 5 of the electromagnet are driven every few coils as shown in FIG. 2 (a). On the other hand, something went wrong. When the capsule 1 stops, all the coils 5 of the electromagnet in the section where the capsule 1 is located are driven as shown in FIG. 2 (b). In addition, it is possible to increase the traveling speed of the capsule 1 by driving all the electromagnet coils while the capsule 1 is traveling.

〔The invention's effect〕

Since the present invention is configured as described above, it has the following useful effects.

By using a non-contact linear motor,
The contact portion between the pipe and the capsule is as small as the wheels only, and high speed operation is possible.

Efficiency is high because the capsule is directly driven by using electricity, and electricity can be easily supplied even in a long-distance section, so that long-distance transportation can be easily performed.

Since current flows only in the section where the capsule is running, current consumption is small and economical.

Since the position of the capsule can be detected and the speed can be controlled, automation is easy.

During steady running, the coils of the electromagnet are driven every few coils, so current consumption is small and economical.

When the capsule is stopped, it can be restarted only by driving the coil of the electromagnet, and troubles such as accidents caused by stopping the capsule can be prevented without using auxiliary means such as a rescue vehicle.
