BACKGROUND OF THE INVENTION
The present invention relates to a transportation facility used for medicine transportation in a hospital, and more specifically, a rail provided with a guide portion in an inner space portion, and a guide portion located in the inner space portion along the rail. The present invention relates to a transport facility provided with a transport vehicle that travels in the form of a transport vehicle, and a transporter of a transport object mounted on the transport vehicle.
[0002]
[Prior art]
For this type of transport equipment, an air purification device that sucks air and purifies the suction air is mounted on the transport vehicle, and this air purification device is connected to the guide portion on the rail side and the guided portion on the transport vehicle side. The thing which made the air suction intensively with respect to the inner space part of the rail in which the contact part exists was proposed previously.
[0003]
[Problems to be solved by the invention]
However, the above-mentioned proposed equipment is very excellent in preventing the diffusion of dust and the like generated by this kind of transport equipment, but the transfer equipment for transported goods is mounted on the transport vehicle. In the configuration, not only the contact point in the inner space of the rail, but also the transfer machine may become a source of dust and the like due to its operation. In this respect, according to the requirements of various installation target facilities There is still room for improvement in preventing the diffusion of dust and the like more reliably.
[0004]
In view of the above situation, the main object of the present invention is to more reliably prevent the diffusion of dust and the like as described above by using an air purification device mounted on a transport vehicle.
[0005]
[Means for Solving the Problems]
[1] In the first aspect of the present invention, in the configuration in which the air purification device that sucks air and purifies the suctioned air is mounted on the transport vehicle together with the transfer device of the transported object, the rail side in the inner space portion of the rail The suction contact portion is a guide contact portion that is a contact point between the guide portion of the transport vehicle and the guided portion on the transport vehicle side, and an arrangement portion of the transfer machine in the transport vehicle, and air suction from the suction target portion to the air purification device Let
[0006]
Therefore, in addition to effectively preventing the diffusion of dust and the like generated by the guide contact portion in the inner space portion of the rail as in the above-mentioned proposed equipment, the transfer machine in the transport vehicle can be Thus, the diffusion of the generated dust and the like can be effectively prevented, and as a whole, the diffusion of the dust and the like can be more reliably prevented as compared with the above-mentioned proposed equipment.
[0007]
Note that the object of diffusion prevention is not limited to dust, but varies depending on the installation target facility, and since the on-board air purification device adopts a purification method corresponding thereto, these various diffusion prevention objects are collectively referred to as dust, etc. Called.
[0008]
In the first aspect of the present invention, since the common air purifying device which is also used as the guide contact portion and the transfer device arrangement portion is sucked by air, for example, the guide contact portion and the transfer device arrangement are arranged. Compared with mounting a dedicated air purifying device for the installation portion on the transport vehicle, the maintenance of the air purifying device can be unified and facilitated.
[0009]
In other words, when the air purifying device for the guide contact portion in the rail inner space portion and the transfer machine placement portion of the transport vehicle are separately provided, dust or the like is generated in the guide contact portion and the transfer device placement portion. Due to the difference in quantity, the required frequency of maintenance for each air purifier differs, and this makes maintenance complicated. However, as described above, the guide contact part and the transfer machine installation part are combined. If the common air purifier is aspirated, it is possible to avoid complication of maintenance caused by the difference in the amount of dust and the like generated, and facilitate maintenance.
[0010]
In the first aspect of the present invention, the switching means for selectively sucking the common air purification device which is also used for the guide contact portion and the transfer device arrangement portion is provided. Compared to suctioning the purification device into the guide contact section and transfer device installation section at the same time, the air purification device can be made with a smaller suction capacity, and the size and weight of the transport vehicle can be increased by installing the air purification device. However, by the selective suction described above, a large suction force is exerted on each of the guide contact portion and the transfer device arrangement portion, and dust generated in the guide contact portion and the transfer device arrangement portion is removed. It can be effectively treated with an air purifier.
[0011]
[ 2 ] In the invention described in claim 2 , the dual-purpose air purification device is caused to suck air with respect to the guide contact portion when the transport vehicle is running, and the dual-purpose air purification device is moved when the transfer machine is operated. Since the switching means is controlled by the control means in accordance with the traveling of the transport vehicle and the operation of the transfer machine so that air is sucked into the mounting machine arrangement section, it is appropriate for changes in the source of dust and the like. Corresponding to the above, dust or the like generated at the guide contact portion or the transfer device arrangement portion can be accurately processed by the air purification device.
[0012]
That is, the guide contact portion in the inner space portion of the rail becomes a source of dust and the like when the transport vehicle travels, and the transferer of the transported object in the transport vehicle becomes a source of dust and the like when operating. The transfer machine operates only when the transport vehicle is stopped to transfer the transported object, and when the transport vehicle travels, the transfer machine is in the operation stop state. The purifying device can be appropriately air-inspired with respect to the one where the dust or the like is actually generated out of the guide contact portion and the transfer device arrangement portion, and thereby the guide contact portion while adopting the selective suction form. And dust generated in the transfer machine arrangement portion can be accurately treated by the air purification device.
[0013]
[ 3 ] In the invention described in claim 3 , the suction duct for the contact portion that guides the suction air from the guide contact portion to the dual-purpose air purification device, and the suction air from the transfer machine installation portion to the dual-purpose air purification device And 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 guided. Compared to adopting a switching structure that simply switches between the contact part direction and the transfer machine installation part direction, reliable suction pressure transmission by the duct and reliable switching by opening and closing the duct internal air path using a damper device, The air purification device can effectively and efficiently suck air into each of the guide contact portion and the transfer machine arrangement portion, and the generated dust or the like can be more reliably processed by the air purification device.
[0014]
[ 4 ] In the invention according to claim 4 , since the air flow wall in a form surrounding the region is formed by the suction action of the air purifying device in the region where the plurality of guide contact portions exist, the dust generated at the guide contact portions Etc. can be reliably sucked into the air purification device together with air while preventing the leakage of the dust and the like from the outside of the region, and the diffusion of the dust and the like can be further reliably prevented.
[0015]

[0027]
As shown in FIG. 4, the air purifiers 33A and 33B are equipped with two devices arranged in a distributed manner before and after the loading portion 1B. These air purifiers 33A and 33B are sucked by the fan 30 and The suctioned air is purified (dust removed) by a filter 31 as a purification means and is discharged from the exhaust port 32 to the outside of the loading portion 1B.
[0028]
That is, the guide contact portion X in the inner space portion of the rail 2 (that is, the contact portion of the traveling wheel 3 and the measuring wheel 18 with respect to the travel guide surface 5, and the contact portion of the retaining ring 4 and the guide wheel 16 with respect to the vibration guide surface 6. ), And an arrangement portion Y of the transfer machine 13 in the transport vehicle 1 (an arrangement portion of the rotary drum 20 in the present embodiment) as suction target portions, air suction from these suction target portions to the air purification devices 33A and 33B. By doing so, the dust generated at the guide contact portion X and the transfer machine arrangement portion Y is collected by the filter 31, thereby preventing the generated dust from being diffused around.
[0029]
As shown in FIG. 6, air suction from the guide contact portion X and the transfer machine placement portion Y is often performed in a rectangular annular arrangement on the base frame 26 of the loading portion 1B facing the lower wall portion of the rail 2. And a rectangular annular structure duct member 35 corresponding to the suction hole arrangement is attached to the lower surface of the base frame 26, whereby a rectangular annular structure duct having a plurality of suction holes 34 on the upper surface side. 36 is formed.
[0030]
Further, the box member 37 is attached to each of the front side lower surface side and the rear side lower surface side of the duct member 35, and the inside of the rectangular annular structure duct 36 and the inside of the box member 37 are communicated by the communication opening 38, At each of the front part and the rear part of the loading part 1B, the air purification devices 33A and 33B are attached to the connecting body of the duct member 35 and the box member 37, and the suction ports 39 of these air purification devices 33A and 33B are connected to the box member 37. Opened inside.
[0031]
Each box member 37 is formed with a suction opening 40 directed toward the loading section facing the transfer machine arrangement section Y (rotary drum arrangement section), and the suction opening 40 and the communication opening 38 described above. Is internally provided with a damper blade 41 that opens and closes by turning around a lateral axis R.
[0032]
That is, as shown in FIG. 4, the box member 37 and the rectangular annular structure duct are operated by operating the front and rear damper blades 41 in a state where the suction opening 40 in the loading portion inward direction is closed and the communication opening 38 is opened. 36, the front and rear air purifying devices 33A and 33B are sucked into the rail inner space portion through the guide contact portion X through the suction holes 34 and the slit opening 2A for insertion of the connecting rod formed in the lower wall portion of the rail 2. On the contrary, as shown in FIG. 5, the box member 37 is loaded by operating the front and rear damper blades 41 so that the suction opening 40 in the loading portion inward direction is opened and the communication opening 38 is closed. The front and rear air purifying devices 33A and 33B are sucked into the transfer machine arrangement portion Y through the suction opening 40 in the inward direction.
[0033]
Further, as a suction structure for the guide contact portion X, a plurality of suction holes 34 are formed in the base frame 26 in a rectangular annular arrangement as described above, so that a plurality of guide contact portions X (that is, the travel guide surface 5 and the front travel surface) are formed. A region where a contact portion with the wheel 3, a contact portion between the traveling guide surface 5 and the rear traveling wheel 3, a contact portion between the traveling guide surface 5 and the front and rear measuring wheels 18, etc.) is surrounded. The airflow wall K of the form is formed by the suction action of the air purifying devices 33A and 33B, and thereby the dust generated at the guide contact portion X is prevented from leaking out of the region by the airflow wall K and the generation thereof Dust is reliably sucked into the air purifiers 33A and 33B together with air.
[0034]
Note that a ventilation opening 2B is formed in the upper wall portion of the rail 2, and guide contact is performed by air suction from the guide contact portion X in a form accompanied by air inflow from the ventilation opening 2B to the rail inner space portion. Dust generated at part X is collected and collected more efficiently.
[0035]
In short, in the present embodiment, the two air purification devices 33A and 33B of the front and rear are both used for the guide contact portion X of the rail inner space portion and the transfer device arrangement portion Y of the transport vehicle 1. The box member 37 and the rectangular annular structure duct 36 connected thereto constitute a suction duct D1 for a contact portion that guides suction air from the guide contact portion X to the front and rear air purification devices 33A and 33B. Each of the box members 37 constitutes a suction duct D2 for a transfer machine that guides suction air from the transfer machine installation portion Y to the front and rear air purification devices 33A and 33B.
[0036]
Then, the front and rear damper blades 41 and the damper motor 41M for rotating the damper blades 41 selectively move the front and rear air purification devices 33A and 33B with respect to the guide contact portion X and the transfer machine arrangement portion Y. As a switching means for sucking air, a damper device 42 for selectively opening and closing the internal air path of the suction duct D1 for the contact portion and the internal air path of the suction duct D2 for the transfer machine is configured.
[0037]
The operation of the damper device 42 is performed by the controller 19. However, the transfer machine 13 is in an operation stop state when the transport vehicle 1 is traveling, and the transfer machine 13 is in operation (that is, when the transport object W is loaded). Since the transport vehicle 1 is in a stopped state at the time of unloading), the controller 19 puts the front and rear damper blades 41 into the closed position with respect to the suction opening 40 when the transport vehicle 1 travels, During operation, the damper device 42 is automatically switched so that both the front and rear damper blades 41 are closed with respect to the communication opening 38.
[0038]
That is, the controller 19 causes the front and rear air purifying devices 33A and 33B to be sucked into the guide contact portion X when the transport vehicle 1 is traveling, and the front and rear air purifying devices 33A and 33B are operated when the transfer device 13 is operated. Control means for controlling the damper device 42 as the switching means according to the traveling of the transport vehicle 1 and the operation of the transfer machine 13 is configured so as to cause the transfer machine placement unit Y to suck air.

Of the things that occur in the guide contact portion X and the transfer machine placement portion Y and have diffusibility, various things can be prevented from spreading according to the requirements of the installation target facility.
[0041]
The purifying means in the air purifying device is not limited to the filter, and various types of devices such as an electric dust collector can be adopted depending on the diffusion prevention target.
[0042]
The air purification device mounted on the transport vehicle 1 may be one device or a plurality of three or more devices, and a common air purification device that is also used as the guide contact portion X and the transfer device arrangement portion Y. Instead of the air suction, the dedicated air purifier may be sucked into the guide contact portion X and the transfer machine arrangement portion Y.
[0043]
Various configurations can be changed for the specific structure of the air purification device and the mounting structure of the air purification device in the transport vehicle 1.
[0044]

In addition, when the air purification device is selectively sucked into the guide contact portion X and the transfer device placement portion Y, the switching means is also limited to the damper device as shown in the above embodiment. Instead, for example, a switching type in which a plurality of suction ports provided in the air purification device are selectively opened or closed or the direction of the suction ports in the air purification device is changed may be employed.
[0045]
Various modifications can be made to the specific structure of the guided portion on the side of the transport vehicle positioned in the inner space portion of the rail 2 and the specific structure of the guide portion in the inner space portion of the rail 2. The transfer method and structure of the transfer machine 13 mounted on the transport vehicle 1 can be variously changed.
[0046]
