It is provided with a drive unit 6 that is moved by the propulsive force of the conductor 2. In this case, the carrier 1 is moved to a predetermined transportation track.
Those other than 4 can be arbitrarily moved by the manual operation of the person 7.
Then, the carrier 1 and the person 7 are placed on the predetermined carrier orbit 4.
The detection unit 5 detects that the carrier 1 is in and out.
It is something to detect. In addition, the transportation track 4 is an inclined surface,
The near motor 3 does not generate propulsive force in the uphill direction.
However, when the carrier 1 descends, the propulsive force in the uphill direction is the braking force.
It is also being acted as.

The carrier 1 in the carrier device is a wheelchair, and the carrier 1 can be arbitrarily moved by a manual operation of a person 7 except for a predetermined track 4. The predetermined transfer track 4 is a slope track, and a linear motor 3 that generates a propulsive force in a direction uphill on the slope track is arranged below the transfer track 4 along the transfer track 4. The linear motor 3 generates a propulsive force by applying an alternating current output from a drive unit 6 formed of a circuit. A detection unit 5 (uphill entrance detection unit 5a, downhill entrance detection unit 5b) formed by a pressure sensor, a photoelectric sensor, or the like is provided at a lower end portion of the transport track 4 that is an uphill entrance and an upper end portion that is a downhill entrance.

Next, the downhill entrance detection unit 5b is confirmed. If the carrier 1 passes through the climbing entrance detection unit 5a and enters the transport track 4,
The drive unit 6 outputs an alternating current to drive the linear motor 3, and the drive of the linear motor 3 is continued until the carrier 1 passes through the downhill entrance detection unit 5b. The carrier 1 is the downhill entrance detection section 5b.
If it is confirmed by the carrier detection signal of the downhill entrance detection unit 5b that the vehicle has passed through and has exited the transportation track 4, the linear motor 3 is stopped and the next step checks the downhill entrance detection unit 5b.

With 7, it is transported and moved smoothly. Moreover, the transportation track
4 is to obtain the propulsive force by the linear motor 3.

Next, when the carrier 1 has passed the detection unit 5c, the linear motor switching device 8 selects the linear motor 3b and switches the application of the alternating current output from the driving unit 6 from the linear motor 3a to the linear motor 3b. Next, if the carrier 1 has passed the detection unit 5d, the linear motor switching device 8 selects the linear motor 3c,
The application of the alternating current output from the drive unit 6 is switched from the linear motor 3b to the linear motor 3c. Furthermore, if the carrier 1 has passed the detection unit 5e, the linear motor switching device 8 selects the linear motor 3d and switches the application of the alternating current output from the driving unit 6 from the linear motor 3c to the linear motor 3d.
Then, if it is confirmed by the carrier detection signal of the downhill entrance detecting section 5b that the carrier 1 has passed through the downhill entrance detecting section 5b and has left the conveyance track 4, the alternating current from the driving section 6 is detected. Stop output. If the carrier 1 passes through the downhill entrance detecting section 5b and enters the conveying track 4, the detecting sections 5a, 5b, 5c,
The order of passing 5d and 5e is the opposite of the order when climbing, and the driving unit 6

Then, if it is confirmed by the carrier detection signal of the uphill entrance detection unit 5a that the carrier 1 has passed through the uphill entrance detection unit 5a and left the transportation track 4, the output of the alternating current from the drive unit 6 is detected. Stop.

Therefore, in the carrying apparatus of this embodiment, in particular, a plurality of linear motors 3a, 3b, 3c, 3d are provided along the carrying path 4, and each linear motor 3a, 3b, 3c, 3d is provided.
A plurality of detection units 5a for detecting the presence of the carrier 1 in correspondence with
Since 5b, 5c, 5d and 5e are provided, only one of the linear motors 3a, 3b, 3c and 3d required to move the carrier 1 is driven, and power consumption is reduced.

Further, in the embodiment, the transfer track 4 is a slope track, but in the transfer device according to claim 3) of the present invention, the transfer track 4 may be a plane track. Further, although the carrier 1 is a wheelchair in the embodiment, in the carrier device according to claim 3) of the present invention, as the carrier 1 which can be arbitrarily moved, a trolley of a factory, a shopping cart of a supermarket, an airport. A baggage cart or the like may be used.

The carrying device shown in FIGS. 8 and 9 is an embodiment of the carrying device according to claims 1) and 2) of the present invention. That is, in particular, the carrying track 4 is inclined in the carrying device.
Surface, the linear motor 3 generates propulsive force in the uphill direction.
Nothing, when the carrier 1 descends, the driving force in the same climbing direction
Is used as a braking force. In this case
In addition, the frequency of the alternating current applied from the drive unit 6 to the linear motor 3 can be switched between the uphill and downhill of the carrier 1.

The carrying device of this embodiment is shown in FIGS. 1, 2 and 3.
The carrier device of the embodiment shown in FIG. 9 is provided with a frequency setting device 9 for setting the frequency of the alternating current. The frequency setting device 9 switches between the uphill frequency and the downhill frequency by the carrier detection signals of the uphill entrance detecting section 5a and the downhill entrance detecting section 5b. Further, the drive unit 6 makes the frequency of the alternating current variable.

Next, based on the flow chart shown in FIG. 10, the operation sequence of the carrying apparatus of this embodiment will be described.
When the carrier 1 passes through the climbing entrance detection unit 5a and enters the transport track 4, the frequency setter 9 sets the climbing frequency, and the drive unit 6 outputs an alternating current of the climbing frequency. The linear motor 3 is driven. Further, when the carrier 1 passes through the downhill entrance detection unit 5b and enters the transportation track 4, the frequency setter 9 sets the downhill frequency, and the driving unit 6 alternates the downhill frequency. The current is output to drive the linear motor 3.

As described above, the reason why the frequency of the alternating current is made different for climbing and descending is that the propulsive force of the linear motor 3 is used as the propulsive force F1 for climbing when climbing and the carrier 1 is used when descending. Braking force F2 to prevent the vehicle from accelerating
Because it is used as. Here, as shown in FIG. 11, since the propulsive force F of the linear motor 3 increases in proportion to the alternating current frequency X, the uphill frequency is set large and the downhill frequency is set small. Therefore, even if the direction of the propulsive force of the linear motor 3 is the same, the magnitude of the propulsive force is smaller on a downhill than on an uphill (F2 <F1) and consumes less power.

Therefore, in the transport apparatus of the embodiment, the frequency of the alternating current applied to the linear motor 3 from the drive unit 6 is particularly inclined when the transport track 4 is inclined and when the transport body 1 climbs and descends. Since it can be switched by the frequency setter 9 and, the linear motor 3
Causes the carrier 1 to move so that a propulsive force acts on the secondary conductor 2, and the carrier 1 is moved so that a braking force acts on the secondary conductor 2 by the linear motor 3 at the time of downhill. Power consumption is reduced.

In the embodiment, the linear motor 3
The difference in the propulsive force was made by changing the frequency of the alternating current applied to the linear motor 3.
It is also possible to change the amplitude of the alternating current applied to the. In the embodiment, the carrier 1 is a wheelchair, but in the carrier device according to claim 2) of the present invention, as the carrier 1 which can be arbitrarily moved, a trolley of a factory, a shopping cart of a supermarket, an airport. A baggage cart or the like may be used.

The carrying device shown in FIG. 12 is an embodiment of the carrying device according to claim 4) of the present invention. That is, in particular, in the carrying device, the sensor 10 for detecting the speed of the carrying body 1 is used. The frequency of the alternating current applied to the linear motor 3 from the drive unit 6 is changed according to the conveyance speed detected by the sensor 10.

The transport apparatus of this embodiment is the same as the transport apparatus of the embodiment shown in FIGS. 8 and 9 except that sensors 10 for detecting the speed of the carrier 1 are provided on both the uphill entrance side and the downhill entrance side. The speed of the carrier 1 detected by the sensor 10 is sent to the frequency setting device 9. The sensor 10, as shown in FIG.
Two photoelectric sensors 11 for detecting the passage of the carrier 1 are arranged at a predetermined interval, and the speed of the carrier 1 is detected by the time of passing between the two photoelectric sensors 11. Next, the frequency setting device 9 uses a sensor so that the speeds during climbing and descending slopes do not change depending on the weight of the person 7 who rides the carrier 1 (wheelchair).
The frequency of the alternating current is calculated from the speed detected in 10. The calculation method in the embodiment is to calculate using the relationship between the propulsive force F and the speed v shown in FIG. 14 and the relationship between the propulsive force F and the alternating current frequency x shown in FIG. For example, when the carrier 1 is moved at the alternating current frequency X, if the speed detected by the sensor 10 is V1, to carry at the set speed V,
An extra ΔF = α (V−V1) is required as a propulsive force. Therefore, the alternating current frequency from the set frequency X,
X1 = (F1 + ΔF−b) / a, and set speed V
The driving force of time is F1 + ΔF.

Next, based on the flow chart shown in FIG. 15, the operation sequence in the carrying apparatus of this embodiment will be described.
When the carrier 1 passes through the climbing entrance detection unit 5a and enters the transport track 4, the frequency setter 9 sets an initial frequency for climbing, and the drive unit 6 outputs an alternating current of the initial frequency for climbing. Then, the linear motor 3 is driven. At that time, the transport speed of the transport body 1 is detected by the sensor 10, and the frequency setting device 9 calculates the optimum frequency by the calculation method. The carrier 1 can climb at a predetermined speed by changing the setting of the frequency setter 9 to the optimum frequency. Further, even when the vehicle is descending, the frequency setter 9 calculates an optimum frequency so as to descend at a predetermined speed and changes the frequency of the alternating current output from the drive unit 6.

Therefore, in the carrying apparatus of this embodiment, in particular, the sensor 10 for detecting the speed of the carrying body 1 is provided, and in accordance with the carrying speed detected by the sensor 10,
Since the frequency of the alternating current applied from the drive unit 6 to the linear motor 3 is changed, the frequency setting device 9 changes and adjusts the frequency of the alternating current so that the conveyance speed is maintained at a predetermined speed. By doing so, it is possible to prevent the transport speed from changing due to the weight change of the transport body 1.

In the embodiment, the linear motor 3
The difference in the propulsive force was made by changing the frequency of the alternating current applied to the linear motor 3.
It is also possible to change the amplitude of the alternating current applied to the. Further, in the embodiment, the transfer track 4 is a slope track, but in the transfer device according to claim 4) of the present invention, the transfer track 4 may be a plane track. Further, in the embodiment, the carrier 1 is a wheelchair, but in the carrier device according to claim 4) of the present invention, as the carrier 1 which can be arbitrarily moved, a trolley of a factory, a shopping cart of a supermarket, an airport. A baggage cart or the like may be used.

Enter the attachment hole 15 of. Then grasp the lever 18 and the anchor 14
Spread, and the secondary conductor 2 is clamped and fixed between the flange 19 and the anchor 14. Then, the secondary conductor 2 is attached to the carrier 1 by lifting the handle 16 from the notch groove 17 of the guide cylinder 12 and rotating it to return it to its original position. Next, when the secondary conductor 2 is removed, the lock is released by further grasping the lever 18, the anchor 14 extends, and the secondary conductor 2 falls downward. In order to firmly fix the secondary conductor 2, a plurality of sets of the guide cylinder 12, the detachable rod 13 and the like are used, or only a plurality of flanges 19 and anchors 14 are provided and a pair of handles 16 and levers are used. It is also possible to make it detachable with 18.

Therefore, in the carrying apparatus of the embodiment, since the secondary conductor 2 is detachably provided on the carrying body 1, when the carrying body 1 is moved on other than the predetermined carrying track 4, The secondary conductor 2 can be removed from the carrier 1 and moved with a lighter burden.
