In this type of conveying device, if the conveying body, which is the secondary movable element of the linear motor, is made of a magnetic material such as a steel plate, the force between it and the linear motor's primary stator is ten to several tens of times the thrust force. A twice as much suction force acts, and this suction force increases the conveyance resistance and reduces the conveyance efficiency, or the object is attracted and cannot be conveyed. In addition, when the carrier is made of a thin steel plate, etc., there is a drawback that the deflection may cause contact with the primary stator core or the surface of the cover for protecting the primary stator, causing damage to the carrier. It was hot.

A conveyance method disclosed in the publication is provided.
That is, a system has been disclosed in which thrust is applied to the pallets by a single-side excitation type linear motor, and the pallets are levitated by conveying air tables arranged alternately adjacent to the linear motors.

つて供給圧力源も大型となる難点がある。 However, in this method, since the floated pallet slides due to inertia while moving to the adjacent linear motor installation position, it is difficult to maintain a constant gap between the pallet and the linear motor, so it is necessary to maintain a constant gap. A control means is required for this purpose. Alternatively, in order to avoid contact between the pallet during inertial sliding and the motor etc., it is necessary to provide a gap larger than necessary, and the supply pressure source is therefore disadvantageously large.

A plurality of linear motor primary stators 3 are provided on the air duct, for example, as shown in FIG. 2, at predetermined intervals in the conveying direction. The table 2 is made of a non-magnetic material such as Bakelite or aluminum, has a size necessary to convey the plate-shaped object 1, and has a flat surface (top surface). A large number of nozzle holes 2a1 are drilled over the entire surface of the table 2 to blow out compressed air so that the plate-shaped body 1 floats slightly above the top surface of the table 2, and

In the apparatus configured as described above, when the plate-shaped body 1 is transported, when the linear motor is driven and compressed air is supplied from the air source, the plate-shaped body 1 is transported by the thrust force of the linear motor. A floating force greater than the suction force generated by this linear motor is obtained, and the plate-shaped body 1 is transported while floating. That is, compressed air supplied from a high-pressure air source passes through an air duct 2b to each nozzle hole 2a1 on the top surface of the table 2 and each nozzle corresponding to the slit 5a cut between the iron cores of the linear motor primary stator 3. From 2a 2 each plate-shaped body 1
Since the air is ejected almost uniformly toward the entire lower surface of the table 2, the plate-shaped object 1 floated by this air pressure becomes higher than the suction force of the linear motor and floats from the table 2, reducing the suction resistance to zero or close to zero. state,
The plate-like object 1 is smoothly transported by effectively utilizing the thrust of the linear motor while maintaining a substantially constant gap over the entire transport section. Further, the primary stator 3 of the linear motor is cooled by compressed air passing through the slit 5a. By adjusting the thickness of the non-magnetic material constituting the upper surface of the table 2, or by adjusting the amount of compressed air injected into the plate-shaped body 1, the relationship between the plate-shaped body 1 and the table 2 when it floats can be adjusted. It is also possible to adjust the air gap to an optimum value.

According to the present invention, the table integrated with the air duct in which the linear motor is installed is made of a non-magnetic material, and compressed air is blown out from this table over the entire length of the table top surface, and compressed air is generated by the linear motor. The plate-shaped body is floated so that the suction force (adsorption force) is eliminated by this ejected air pressure, and a substantially constant gap is maintained over the entire length of the conveyance section, so the thrust force of the linear motor is not reduced and the suction force is eliminated. It has the advantage of completely eliminating the sub-effects of force and contact with the table surface due to the weight of the plate-shaped body, allowing transportation in a stable state, and cooling the linear motor at the same time with the flow of compressed air.
