Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport system used for transporting medicines in hospitals, and more particularly, to a rail having a guide portion in an inner space and a guided portion located in the inner space. The present invention relates to a transporting facility provided with a transporting vehicle that travels along the rails in a state where the transporting device is mounted on the transporting vehicle.

[0002]

2. Description of the Related Art With regard to this type of transfer equipment, an air purifying device for purifying the sucked air by sucking air is mounted on a transfer vehicle, and the air purification device is connected to a guide section on a rail side and a transfer side. The one that intensively sucks air into the inner space of the rail where the contact point with the guided part exists is proposed earlier.

[0003]

However, in order to prevent the diffusion of dust and the like generated by this type of transport equipment as a source, the above-mentioned proposed equipment is extremely excellent. In the configuration in which the transfer machine is mounted on the carrier, not only the above-mentioned contact point in the inner space of the rail but also the transfer machine may be a source of dust and the like due to its operation. There is still room for improvement in preventing the diffusion of dust and the like more reliably according to the requirements of the installation target facility.

[0004] In view of the above situation, a main problem of the present invention is to prevent the above-mentioned diffusion of dust and the like with an air purifying device mounted on a transport vehicle more reliably.

[0005]

[Means for Solving the Problems]

[1] According to the first aspect of the present invention, in the configuration in which the air purifying device for purifying the sucked air by suctioning air is mounted on the transport vehicle together with the transfer device of the transported material, the rail side in the inner space of the rail is provided. The guide contact portion, which is the contact point between the guide portion of the transfer vehicle and the guided portion of the transport vehicle, and the portion where the transfer machine is provided in the transport vehicle are suction target portions. Let it.

Therefore, the diffusion of dust and the like generated by the guide contact portion in the inner space of the rail as a source can be effectively prevented in the same manner as the above-mentioned proposed equipment, and the transfer machine in the transport vehicle can be prevented. Can also effectively prevent the diffusion of dust and the like generated as a source, whereby the diffusion of dust and the like can be more reliably prevented as a whole as compared with the above-described proposed equipment.

[0007] The object of diffusion prevention is not limited to dust, but varies depending on the installation target facility, and the air purification device mounted on the device adopts a purification method corresponding to that.
These various diffusion prevention targets are collectively referred to as dust and the like.

[2] According to the second aspect of the present invention, a common air purifying device, which is shared, is sucked into the guide contact portion and the transfer device disposition portion by air. Maintenance of the air purification device can be centralized and facilitated compared to mounting a dedicated air purification device for each of the transfer device disposition section and the transport vehicle.

In other words, if the air purifying device for the guide contact portion in the rail inner space and the transfer device disposition portion of the transport vehicle are separately provided, dust at the guide contact portion and the transfer device disposition portion is different. Due to the difference in the amount of generated air, etc., the required frequency of maintenance for each air purification device is different, and this makes the maintenance complicated, but as described above, the guide contact portion and the transfer device disposition portion If the common air purifying device is also used for air suction, it is possible to avoid complicated maintenance due to such a difference in the amount of dust and the like, and to facilitate the maintenance.

[3] According to the third aspect of the present invention, a switching means for selectively sucking air from a common air purifying device that is shared is provided for the guide contact portion and the transfer device disposing portion.
For example, the air purifying device requires only a small suction capacity as compared with the simultaneous use of the air purifying device for the guide contact portion and the transfer device disposing portion. While avoiding the increase in size and weight, the above-mentioned selective suction exerts a large suction force on each of the guide contact portion and the transfer device disposition portion, and the guide contact portion and the transfer device disposition portion cause a large suction force. The generated dust and the like can be effectively treated by the air purification device.

[4] According to the fourth aspect of the present invention, when the carrier is traveling, the dual-purpose air purifying device sucks air into the guide contact portion, and when the transfer machine operates, the dual-purpose air purifying device is used. The switching means is controlled by the control means in accordance with the traveling of the carrier and the operation of the transfer machine so that the apparatus is caused to suck air into the transfer machine arrangement portion. The dust and the like generated in the guide contact portion and the transfer device disposition portion can be appropriately treated by the air purifying device.

That is, the guide contact portion in the inner space of the rail serves as a source of dust and the like when the transport vehicle travels. However, the transfer machine operates only for the transfer of the conveyed goods when the carrier is stopped, and the transfer machine is in an operation stop state when the carrier is traveling, so if the automatic switching as described above is performed, The dual-purpose air purifying device can appropriately suction air from the guide contact portion and the transfer device disposing portion where dust or the like is actually generated, thereby adopting a selective suction mode, Dust and the like generated at the guide contact portion and the transfer device disposition portion can be accurately treated by the air purification device.

[5] According to the fifth aspect of the present invention, the suction duct for the contact portion for guiding the suction air from the guide contact portion to the dual-purpose air purification device, and the dual-purpose air purification device from the transfer device disposition portion. A suction duct for a transfer machine that guides suction air to
And, since a damper device for selectively opening and closing the internal air passages of these suction ducts is provided as the switching means, for example, the direction of the suction port of the air purification device is set to the direction of the guide contact portion and the direction of the transfer device disposition portion. As compared with the switching configuration that simply switches the air pressure, the suction pressure transmission by the duct and the reliable switching by the opening and closing of the air duct inside the duct using the damper device make it possible to switch between the guide contact section and the transfer machine installation section. The air purifying device effectively and efficiently sucks air into the air purifying device, so that the generated dust and the like can be more reliably processed by the air purifying device.

[6] In the invention according to claim 6, the air flow wall of the form surrounding the region is formed by the suction action of the air purification device in the region where a plurality of guide contact portions exist. The generated dust and the like can be reliably sucked into the air purification device together with the air while the generated dust and the like are prevented from leaking to the outside of the region by the airflow wall, whereby the diffusion of the dust and the like can be more reliably prevented.
