Abstract

PURPOSE:To aim at enhancing the productivity by providing magnetically floating rails on floors and an elevators, and by arranging a magnetically floatable type carrier vehicle on the rails so that the elevator is moved up and down between the floors. CONSTITUTION:A vertically movable elevator 3 is disposed in an elevating passage 2 connecting among a plurality of floors of clean rooms 1A through 1C. A magnetically floating rail 5 made of magnetic material 4 is laid in a cargo storage chamber 4 held in a clean condition, which is formed in the elevator 3, and a magnetically floatable carriage vehicle 6 is allowed to travel on the rail being magnetically floated up. Similar magnetically floating guide rails 5a, 5b are laid on the ceilings of the clear rooms on the floors. With this arrangement, the carriage vehicle 6 is moved between the elevator 3 and a certain floor the elevator has reached, through guide rails 5a, 5b. Thereby it is possible to aim at enhancing the efficiency of conveying work.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention moves a conveyance vehicle between an elevating body that ascends and descends between a plurality of floors and each floor via a magnetic levitation device. This invention relates to a magnetic levitation transport device.

(Prior Art) When transporting cargo between the upper and lower floors of a clean room consisting of multiple floors, conventionally, as shown in FIG. The cargoes 10A and 1013 are placed on the cargo tray 11 in the room 4, and the elevating body 3 is moved up and down to move the cargoes 10A and IOB to the desired floor.

(Problems to be Solved by the Invention) However, the above-mentioned conventional device requires a transfer device to transfer the cargo, and the transfer operation takes time, reducing productivity. be.

The present invention moves a magnetically levitated near-motor transport vehicle between an elevating body and multiple floors, thereby efficiently transferring cargo between multiple floors without using a special transfer device. The purpose of the present invention is to provide a magnetic levitation conveyance device.

[Structure of the invention]

(Means and effects for solving the problems) The present invention provides an elevating body that moves up and down between a plurality of floors, a guide rail for magnetic levitation provided on the elevating body, and a guide rail at a stop position of the elevating body with respect to each floor. A magnetic levitation guide rail is installed on each floor on the extension line of the building, and a magnetic levitation carrier that can move along each guide rail is installed. This allows luggage to be efficiently transferred between each floor.

(Example) An example of the present invention is shown in FIG. Moreover, FIG. 2 shows the planting of the elevating body used in the present invention.

In Figure 1, a clean room IA on multiple floors,
A hoistway 2 passes through between 1B and IC, and an elevating body 3 moves up and down within this hoistway.

Inside the elevating body 3, as shown in FIG. 2, there is a baggage storage chamber 4 kept in a clean state by a clean unit 12 and a filter 13, and a guide rail 5 whose lower surface is made of ferromagnetic material. A linear motor stator 7 is arranged to apply a propulsion force along the guide rail to the transport vehicle 6, and a magnetic support unit 8A is provided on the transport vehicle 6 in opposition thereto.

8B and the linear motor stator body 9, the transport vehicle 6 is moved horizontally while being floated and supported, and the cargo 10A,
IOB is transported. Note that 14 is a mesh plate for passing clean air.

In addition, guide rails 5a and 5b for each floor are provided on the ceiling of the clean room on each floor on the extension line of the guide rail 5 at the stop position of the elevating object 3, so that when the elevating object 3 stops at the desired floor, The transport vehicle 6 moves along the guide rails 5a and 5b from the elevator 3 toward the clean room by the thrust of the linear motor 7, thereby smoothly moving between each floor of the clean room without using a special transfer device. It becomes possible to transfer luggage.

〔Effect of the invention〕

As explained above, according to the present invention, the magnetic levitation near-motor type transport vehicle is configured to be able to move along the guide rails of the elevator and each floor of the clean room, so that the transport vehicle can move between the elevator and each floor of the clean room. It is now possible to board the vehicle directly to and from the floor, so there is no need for special transfer equipment.
Transport work between clean rooms on multiple floors can be carried out efficiently.

Note that the present invention can be applied not only to clean rooms but also to other similar conveyance devices.
