In the figure, reference numeral 1 denotes a linear motor type transport vehicle, which is equipped with a cart 2 on which transported objects 3 such as luggage are mounted. A movable coil 5 and a linear motor movable element 4 are provided on a part of the ground side of this bogie 2, and in order to maintain the gap between the ground and the bogie 2 at a constant interval, gap maintaining means such as rolling bearings are provided. 10 have been installed. On the other hand, on the ground side, a linear motor stator 6 is installed facing the linear movement direction of the linear motor mover 4, and a secondary conductor 7 such as an aluminum plate and a secondary yoke 8 such as a steel plate are closely connected. It is laid down. Reference numeral 9 denotes a stator-mover gap (hereinafter referred to as a gap) between the linear motor mover 4 and the linear motor stator 6.

ずる。Next, the function and operation of the conventional linear motor conveyance device having the above configuration will be explained. Place the conveyed object 3 on the trolley 2,
When a driving power source is supplied to the linear motor mover 4 provided on the trolley 2, the linear motor carrier 1 begins to move opposite the linear motor stator 6 laid on the ground. This linear motor type carrier 1 is characterized by a very simple configuration, but normally a suction force that is several times as large as that of the thruster is applied to the gap 9, and the rolling bearings, etc. The gap maintaining means 10 has disadvantages in terms of extra load due to friction and economic efficiency due to its own lifespan. If you try to reduce the attractive force to improve this problem, you will end up with a design that lowers the magnetic flux density.
In this case, the basic characteristics of the linear motor, such as thrust and weight, deteriorate.
従来のリニアモータ搬送装置は以上のように構成されて

駆動用電源を遮断した場合に吸引力を維持する手段を持

不能、例えば落下などが伴なうなどの欠点があった。Since the conventional linear motor conveyance device is configured as described above, it does not have any permanent magnets or electromagnets.
If it is necessary to have a means to maintain the suction force when the drive power is cut off, turning the drive power on and off will cause large impact load fluctuations on the bearing, which may make it impossible to maintain the gap, for example, if the product falls. There were some drawbacks, such as:

としている。This invention was made in order to eliminate the above-mentioned drawbacks of the conventional one, and includes a holding magnetic means using an electromagnetic attraction force between the gaps and an air bearing for sending out pressurized air. It is an object of the present invention to provide a highly reliable linear motor transport device that can operate without problems of friction and longevity.

。An embodiment of the present invention will be described below with reference to FIGS. 2(a) and ('b). In the figure, 1 to 9 indicate the same or corresponding parts as the same reference numerals in FIG. Reference numeral 11 denotes a holding magnetic means such as a permanent magnet that is parallel to the ground side of the truck 2, and as shown in the back view of the movable element side in FIG. 11a to lid are provided. Further, 12th C is an air bearing disposed at the center of each of the magnets 11a to lid toward the earth side, and each of the air bearings 128 to 12d is all connected to the air supply pipe 13.

First, during driving, pressurized air is supplied from each air bearing 12a to 12d via an air supply pipe 13 so as to repel the attraction force by the holding magnetic means 11, in order to maintain the gap 9 between the fixed movable element at a predetermined interval. is sent to gap 9.

っている。When the drive power is applied to the linear motor mover 4 after the gap 9 maintains a predetermined distance, the linear motor carrier 1
begins to move opposite the linear motor stator 6. In this case, the attraction force by the holding magnetic means 11, which is sufficiently large compared to the weight of the conveyed object 3 mounted on the trolley 2, can be canceled out by the repulsive force by the air bearing 12 to maintain the predetermined gap.
The linear motor transport vehicle 1 has sufficient spring force against the ground.

を奏する。In the above embodiment, the linear motor stator 6 is provided on the ground side, and the linear motor transport vehicle 1 provided with the linear motor mover 4 moves on the ground, but as shown in FIG. The stator 6 may be suspended from the ceiling, and the linear motor carrier 1 may move underneath it; in this case,
Even if the air supply is stopped, it is safe because it does not fall due to the suction force of the holding and holding magnetic means 11, and the same effect as the above embodiment is achieved.

The child 4 and the holding magnetic means 11 may be provided respectively. In this case, there is double safety against falling accidents, and the same effects as in the above embodiments are achieved.

上記実施例と同様の効果を奏する。Furthermore, in the above embodiment, the arrangement of the linear motor stator 6 and the linear motor mover 2 may of course be exchanged.
The same effects as in the above embodiment are achieved.

This has the effect of providing a highly reliable linear motor conveyance device that has spring force and is less susceptible to load fluctuations due to the linear motor and power on/off.
