Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention is a transport device that is used in a magnetic levitation type transport device for transporting small articles, and that allows transport vehicles to be taken in and out in an emergency. related to the road.

(Prior Art) In recent years, as part of office automation and factory automation, it has become common practice to move slips, documents, cash, materials, and the like between multiple locations within a building using a transport device.

Conveyance devices for such uses are required to be able to move the conveyed objects quickly and without making noise. For this reason, in this type of transport device, the transport vehicle is supported on the guide rail in a non-contact manner. Among these, the method of magnetically supporting the conveyance vehicle in a non-contact manner has excellent followability to guide rails and is effective in preventing noise and dust generation.

In such a magnetic support method, the transport path requires a structure that can support the transport vehicle even if the transport vehicle falls due to a failure of the control device, an excessive external force applied to the transport vehicle, or the like.

This prevention of falling is based on a structure in which the conveyance vehicle is held by an emergency guide on the conveyance path side, so it is necessary to take the conveyance vehicle in and out of the conveyance path for maintenance and inspection at the end of the conveyance path.

However, if there is no such end of the transport path in a long transport path section and the transport vehicle breaks down in this section, the transport vehicle must be moved to the end of the transport path using auxiliary wheels, which requires a lot of work. It's not easy.

Furthermore, since the transport vehicle is driven over long distances using the auxiliary axle, the generation of dust from the axle also becomes a problem.

(Problems to be Solved by the Invention) As described above, in a conveyance path that is shaped to hold the conveyance vehicle with an emergency guide or the like to prevent the conveyance vehicle from falling,
In an emergency, the place where the transport vehicle can enter and exit the transport path is limited to the end of the transport path.

Therefore, an object of the present invention is to provide a transport path that facilitates the entry and exit of transport vehicles in emergencies.

[Structure of the invention]

(Means for solving the problem) In the conveyance path according to the present invention, except for one ferromagnetic rail,
A part of the emergency guide and track frame shaped to hold the transport vehicle can be opened within a range of one vehicle length or more.

(Function) According to the present invention, there is provided an emergency guide rail having a structure to support the conveyance vehicle when it is not magnetically levitated.

And a part of the track frame by a length longer than the carrier vehicle length,
By having an openable structure, it is possible to take the transport vehicle in and out of the transport path even at a location other than the end of the transport path.

(Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, there are two guide trays formed of ferromagnetic material on the lower surface of the upper wall of the track frame 11a.

emergency guides 13 each having a U-shaped cross section are fixed to the inner surfaces of both side walls of the track frame 11 with their open sides facing each other. And these orbital frames 11
The guide rail 12 and the emergency guide 13 collectively form a conveyance path. Below the guide rail 12, the weight of the transport vehicle is magnetically suspended and supported along the guide rail.
It becomes possible to run freely.

On the conveyance path, the track frame 11 and the emergency guide 13
The length of the transport vehicle is at least longer than the length of the vehicle and has an open part of 11.
a, 13a are fixed by a connecting portion 14.

As can be seen from FIG. 1, the transport path is supported by emergency guides 13a and 13b to prevent it from falling by the transport vehicle auxiliary wheels 21 even when the transport vehicle is not floating. . Conventionally, the weight of the conveyed vehicle could be taken out from the conveyance path having such a shape only from the end of the conveyance path, but according to the embodiment of the present invention, a removable open part 11a, 13a is constituted by a connecting part 14, so by removing the above-mentioned parts at this point and opening the side surface on the transport path, the transport vehicle -? You can take out the machine. In this way, in an emergency such as when the conveyance vehicle cannot be controlled to float, the conveyance vehicle -2- can be taken out not only at the end of the conveyance path but also at the above-mentioned dividing point.

Note that the present invention is not limited to the embodiments described above, and as shown in FIG. , it is also possible to have a structure that can be rotated as shown by arrow a, but a fixed support mechanism is provided to prevent rotation at all times.

〔Effect of the invention〕

As described above, according to the present invention, in the event of an emergency such as when the levitation control of the transport vehicle is no longer possible, the transport vehicle can be transported without moving on the emergency guide to the end of the transport path using the transport vehicle auxiliary wheels. Since the transport vehicle can be taken in and out from the open portion provided in the middle of the road, dust generation due to wheel running of the transport vehicle is reduced and maintainability of the transport vehicle is facilitated.
