Description

Technical Field

[0001] The present invention relates to article conveying equipment including an article conveying device and a fireproof door. Background Art

[0002] For example, Japanese Patent Gazette No. 6304057 (Patent Document 1) discloses an article conveying facility having an article conveying device (2) that conveys articles (1) across multiple floors through openings (f) formed in floor portions (F) of each floor. The article conveying facility is provided with a fire door (34) that opens the opening (f) in normal times and closes the opening (f) in the event of a fire. The reference numerals in parentheses in the above description are those of Patent Document 1. Summary of the Invention

[0003] Problems to be solved by the invention

[0004] In an article conveying facility equipped with the aforementioned article conveying device, for example, arranging two article conveying devices side by side to increase the amount of conveyable articles is a possible approach to improve article conveying efficiency. In this case, while maintenance of the article conveying devices may be necessary, by separating the two with a partition wall to allow for independent maintenance of the two article conveying devices, the safety of the maintenance operator can be ensured, even when one article conveying device is being maintained while the other is in operation.

[0005] Incidentally, if an article conveyor is installed across fire-protected zones such as floors or walls, fire doors are necessary to seal the openings in the floors or walls that allow the article conveyor to pass through in the event of a fire. In the case of two article conveyors as described above, one fire door could be installed in the zone containing one article conveyor and the other, separated by a dividing wall. However, increasing the number of fire doors would lead to a corresponding increase in cost and installation space. Alternatively, a single fire door could be installed, with a cutout in a portion of the dividing wall that connects the two zones, allowing the fire door to span the two zones.

[0006] However, in a configuration where the fire door is shared by both zones, the cutout in the partition wall becomes open when the fire door is open. With the cutout in this position, when maintenance is being performed in one zone, for example, the operator's hands or feet, or equipment used for maintenance, could potentially escape through the cutout into the other zone, rendering the article conveying device inoperable in the other zone.

[0007] In view of the above circumstances, in article transport equipment including a partition wall separating two article transport devices along a transport path, a technology is desired that can arrange a fire door across the partition wall while properly partitioning both sides of the partition wall.

[0008] Means used to solve problems

[0009] The article conveying equipment includes a first conveying path and a second conveying path arranged parallel to each other along a conveying direction in which articles are conveyed, a first conveying device moving along the first conveying path, and a second conveying device moving along the second conveying path, comprising: a partition wall separating the first conveying path and the second conveying path along the conveying direction; an object wall arranged so as to intersect the conveying direction; an opening penetrating the object wall in the conveying direction and allowing both the first conveying path and the second conveying path to pass through; and a fire door moving parallel to an opening surface of the opening and changing its state between a closed state in which the opening is blocked and an open state in which the opening is opened and both the first conveying path and the second conveying path are open. ; A cutout portion is formed in the aforementioned partition wall in an area overlapping with the door movement trajectory serving as the movement trajectory of the aforementioned fire door; the aforementioned fire door is arranged across both sides of the aforementioned partition wall in a state of penetrating the aforementioned cutout portion in the aforementioned closed state; a direction orthogonal to the aforementioned partition wall is set as a wall-orthogonal direction, and a movable hood is provided on the aforementioned partition wall, and the state of the movable hood changes to an overlapping state in which it is arranged to overlap with the aforementioned cutout portion when viewed along the wall-orthogonal direction of the aforementioned wall, and a retreat state in which it retreats from the aforementioned door movement trajectory; the aforementioned movable hood is forced to become the aforementioned overlapping state in the aforementioned open state of the aforementioned fire door, and becomes the aforementioned retreat state as it is pushed by the aforementioned fire door in the closing action used to change the state of the aforementioned fire door from the aforementioned open state to the aforementioned closed state.

[0010] According to this structure, since a cutout is formed in the area of ​​the partition wall that overlaps with the door's trajectory, a fire door can be placed across both sides of the partition wall. When the fire door is closed, the fire door can be placed so that it overlaps both the first and second conveyor paths, thereby blocking the opening in the target wall. Thus, the fire door can be shared by both the first and second conveyor paths, reducing the cost and installation space associated with the increased number of fire doors. Furthermore, when the fire door is closed, the movable hood installed in the partition wall is pushed by the closing fire door, retreating from the door's trajectory. On the other hand, when the fire door is open, opening both the first and second conveyor paths, the movable hood is placed in an overlapping position, overlapping the cutout when viewed orthogonally to the wall. Therefore, the overlapping movable hood can block the area on the side of the partition wall where the first conveyor path is located and the area on the side where the second conveyor path is located. Therefore, according to this structure, the fire door can be arranged across both sides of the partition wall by means of a cutout formed in the partition wall, and the two sides of the partition wall can be appropriately separated by means of a movable hood that is arranged in an overlapping state to overlap relative to the cutout when viewed in a direction orthogonal to the wall.

[0022] Article transport equipment is equipment that transports and stores raw materials, intermediate products, finished products, etc. Hereinafter, embodiments of the article transport equipment will be described, exemplified by the case where the article transport equipment is installed in a clean room where raw materials are processed in a clean environment.

[0023] like Figure 1 and Figure 2 As shown, the article conveying equipment 100 includes a ceiling conveyor 99, a floor conveyor 98, a first conveyor 1, and a second conveyor 2. These are installed in a building having a multi-story floor portion 4. The ceiling conveyor 99 travels near the ceiling of each floor to convey articles W. The floor conveyor 98 travels on the floor of each floor to convey articles W. The first conveyor 1 conveys articles W while being supported by a first guide rail 11 arranged along a first conveying path P1. The second conveyor 2 conveys articles W while being supported by a second guide rail 21 arranged along a second conveying path P2. In this embodiment, the first and second guide rails 11 and 2 are arranged adjacent to each other in parallel and vertically penetrate the multi-story floor portion 4. Furthermore, the first and second conveyor 1 and 2 are configured to vertically convey articles W across multiple floors. Furthermore, as the article W, for example, a storage container (FOUP (Front Opening Unified Pod) or reticle cassette) that stores semiconductor substrates or reticle substrates can be exemplified.

[0024] In this embodiment, the article transport facility 100 is provided with a surrounding wall 96 that surrounds a first conveying path P1, which serves as a conveying path for articles W by the first conveyor device 1, and a second conveying path P2, which serves as a conveying path for articles W by the second conveyor device 2. The surrounding wall 96 surrounds the first conveying path P1 and the second conveying path P2 along the conveying direction in which the first conveyor device 1 and the second conveyor device 2 convey the articles W. Specifically, within the surrounding wall 96, there are the first conveying path P1 and the second conveying path P2, which are arranged parallel to each other along the conveying direction in which the articles W are conveyed; the first conveyor device 1, which moves along the first conveying path P1; and the second conveyor device 2, which moves along the second conveying path P2. In this embodiment, the surrounding wall 96 is formed into a cylindrical shape with a rectangular cross-section.

[0025] As described above, the first conveyor device 1 and the second conveyor device 2 are installed inside the surrounding wall 96 . On the other hand, the ceiling conveyor device 99 and the floor conveyor device 98 are installed outside the surrounding wall 96 .

[0026] like Figure 1 As shown, the article transport facility 100 includes an inlet / outlet transport device 97, which is provided on each floor and transports articles W into and out of the surrounding wall 96. The inlet / outlet transport device 97 is provided so as to extend horizontally through the surrounding wall 96, spanning both the interior and exterior of the surrounding wall 96. The inlet / outlet transport device 97 transports articles W between an end portion located outside the surrounding wall 96 (external end portion 97a) and an end portion located inside the surrounding wall 96 (inner end portion 97b). The inlet / outlet transport device 97 is constructed using a conveyor mechanism such as a belt conveyor or a roller conveyor.

[0027] A plurality of holding portions 7 for holding articles W are provided inside the surrounding wall 96 (see FIG. Figure 3 and Figure 4 In this embodiment, the holding portion 7 includes a support body 70 capable of supporting the article W from below, and is configured to hold the article W by supporting the article W with the support body 70. The holding portion 7 functions as a so-called buffer portion for temporarily placing the article W during transportation. Figure 2 The holding portion 7 is omitted.

[0028] When an article W is placed on the outer end 97a of the in-and-out conveyor 97 by the ceiling conveyor 99, the floor conveyor 98, or a worker, the article W is conveyed by the in-and-out conveyor 97 to the inner end 97b within the surrounding wall 96. The article W is then transported by the first conveyor 1 or the second conveyor 2 from the inner end 97b to the inner end 97b of the in-and-out conveyor 97 on another floor. The article W transported to the inner end 97b is then transported by the in-and-out conveyor 97 to the outer end 97a and then transported by the ceiling conveyor 99, the floor conveyor 98, or a worker to the next process location. Furthermore, if an article W is temporarily placed in a holding section 7 during such transport, the first conveyor 1 or the second conveyor 2 transports the article W to an empty holding section 7. The first conveyor 1 or the second conveyor 2 then transports the article W temporarily placed in the holding section 7 to the inner end 97b of the in-and-out conveyor 97 on a certain floor.

[0029] Below, refer to Figures 2 to 8 The structures of the first conveyor 1 and the second conveyor 2 and the surrounding structures of these devices will be described in detail. Hereinafter, the direction in which the articles W are conveyed by the first conveyor 1 and the second conveyor 2 will be simply referred to as the "conveying direction." In this embodiment, the conveying direction is defined as a direction along the vertical direction.

[0030] like Figures 2 to 5 As shown, the article conveying equipment 100 includes a target wall 4T, which is arranged so as to intersect with the conveying direction. Specifically, the target wall 4T is arranged so as to be orthogonal to the conveying direction and the partition wall 5 described later. In this embodiment, the target wall 4T is provided as the floor portion 4 of the equipment. Specifically, the target wall 4T is provided as the floor portion 4 other than the floor portion 4 of the lowest layer of the article conveying equipment 100. Figure 1 3 illustrates a three-story article transport facility 100, in which the floor portions 4 on the second and third floors are target walls 4T. The floor portion 4 on the first floor is not a target wall 4T.

[0031] The article conveying equipment 100 includes a partition wall 5 that separates the first conveying path P1 from the second conveying path P2 along the conveying direction. In the present embodiment, the partition wall 5 is provided inside the surrounding wall 96. In this example, the partition wall 5 is arranged along the vertical direction. The interior of the surrounding wall 96 is divided by the partition wall 5 into a first area A1 in which the first conveying device 1 is arranged, and a second area A2 in which the second conveying device 2 is arranged. The first conveying device 1 is configured to convey articles W in the vertical direction in the first area A1. The second conveying device 2 is configured to convey articles W in the vertical direction in the second area A2. Hereinafter, the direction perpendicular to the partition wall 5 is referred to as the wall-perpendicular direction X. Furthermore, in the wall-perpendicular direction X, the side on which the first conveying device 1 is arranged relative to the partition wall 5 is referred to as the wall-perpendicular direction first side X1, and the side on which the second conveying device 2 is arranged relative to the partition wall 5 is referred to as the wall-perpendicular direction second side X2. Furthermore, in the present embodiment, the wall-perpendicular direction X is referred to as a direction along the horizontal direction.

[0032] The first conveying device 1 includes: a first guide rail 11, which is arranged across multiple layers along the conveying direction (in this example, the vertical direction); a first lifting body 13, which is lifted and lowered along the first guide rail 11; and a first transfer unit 14, which is supported by the first lifting body 13 and performs holding and transfer of articles W. In this embodiment, the first transfer unit 14 includes a first transfer and holding unit 141 capable of holding articles W, a mechanism for moving the first transfer and holding unit 141 forward and backward in the horizontal direction, and a mechanism for rotating the first transfer and holding unit 141 around an axis along the vertical direction. Thus, the first transfer unit 14 can transfer articles W between a plurality of holding units 7, which are arranged at a plurality of locations around the first guide rail 11 so as to be horizontally separated from the first guide rail 11. For example, the first transfer unit 14 is constructed using a horizontal multi-jointed arm (so-called SCARA; Selective Compliance Assembly Robot Arm). In the example shown in the drawings, a pair of first transfer units 14 are aligned in the vertical direction and supported by the same first elevating body 13 .

[0033] The second conveying device 2 includes: a second guide rail 21 arranged across multiple layers along the conveying direction (in this example, the vertical direction); a second lift 23 that rises and falls along the second guide rail 21; and a second transfer unit 24 supported by the second lift 23 for holding and transferring articles W. In this embodiment, the second transfer unit 24 includes a second transfer and holding unit 241 capable of holding articles W, a mechanism for moving the second transfer and holding unit 241 forward and backward in the horizontal direction, and a mechanism for rotating the second transfer and holding unit 241 about an axis extending in the vertical direction. Thus, the second transfer unit 24 can transfer articles W between a plurality of holding units 7 arranged horizontally away from the second guide rail 21 at various locations around the second guide rail 21. For example, the second transfer unit 24 is constructed using a horizontal multi-jointed arm. In the illustrated example, a pair of second transfer units 24 are arranged in the vertical direction and supported by the same second lift 23. As described above, in this embodiment, the first transport device 1 and the second transport device 2 have the same structure.

[0034] The article transport facility 100 includes an opening 40 that penetrates the target wall 4T in the transport direction, and both the first transport path P1 and the second transport path P2 pass through the opening 40. Figure 1 In the example shown, openings 40 are formed in each of the floor sections 4 on the second and third floors, which serve as the target walls 4T. The openings 40 are formed to vertically penetrate each of these floor sections 4. Both the first guide rail 11 and the second guide rail 21 are inserted through the openings 40. When viewed from above, the openings 40 are formed to be larger than the combined area of ​​the first and second conveyor devices 1 and 2. The first and second conveyor devices 1 and 2 travel between the floors through the openings 40.

[0035] The article conveying equipment 100 includes a fire door 3, which moves parallel to the opening surface of the opening 40, and changes its state between a closed state in which the opening 40 is blocked and an open state in which the opening 40 is opened and both the first conveying path P1 and the second conveying path P2 are opened. The fire door 3 is configured to move along the floor portion 4. That is, in this example, the door movement direction Y, which is the movement direction of the fire door 3, is set to be a direction along the object wall 4T (floor portion 4) arranged orthogonal to the partition wall 5. In this embodiment, the door movement direction Y is further set to be a direction orthogonal to the wall orthogonal direction X. In the example shown in the figure, the fire door 3 is configured to be supported by a door support frame 30 provided on the object wall 4T, and is guided by the door support frame 30 to move along the door movement direction Y. As Figure 8As shown, in the closed state, the fire door 3 abuts against the frame end 30a of the door support frame 30, which is arranged opposite the fire door 3 in the door movement direction Y. By abutting against the frame end 30a in the closed state, the fire door 3 blocks the opening 40 in a plan view. Hereinafter, in the door movement direction Y, the side of the fire door 3 that moves due to the closing operation for changing the state from the open state to the closed state is referred to as the first door movement direction side Y1, and the side of the fire door 3 that moves due to the opening operation for changing the state from the closed state to the open state is referred to as the second door movement direction side Y2.

[0036] Figures 2 to 6 The fire door 3 is shown in an open position. When the first conveyor 1 and the second conveyor 2 are operating, the fire door 3 is in an open position. Furthermore, when maintenance is being performed in at least one of the first area A1 and the second area A2, for example, the fire door 3 is also in an open position. In this embodiment, the article conveyor system 100 is provided with a first work platform 91 and a second work platform 92, each of which can be configured to partially cover the opening 40. The first work platform 91 is configured to partially cover the opening 40 in the first area A1 when deployed, and the second work platform 92 is configured to partially cover the opening 40 in the second area A2 when deployed. The first and second work platforms 91, 92 are configured to effectively serve as a scaffolding for operators during maintenance and to be folded and stored when not in use. This figure shows the first and second work platforms 91, 92 in a folded and stored position. In addition, in the example shown in the figure, a first ladder L1 is provided in the first area A1, and a second ladder L2 is provided in the second area A2. The first ladder L1 and the second ladder L2 can also be used during maintenance. The first ladder L1 and the second ladder L2 are provided so as to be freely detachable and can be disassembled when no maintenance is performed. Furthermore, in the present embodiment, a plurality of emergency stop switches S are provided for stopping the operation of the first conveying device 1 or the second conveying device 2. The emergency stop switches S are used by operators performing maintenance, etc. as needed. In the example shown in the figure, the emergency stop switches S are provided at multiple locations on the inner and outer sides of the surrounding wall 96. Thus, operators, etc. can press the emergency stop switches S from both the inside and the outside of the surrounding wall 96.

[0037] Figure 8This shows the fire door 3 in a closed state. When a fire occurs, the fire door 3 closes, blocking the opening 40 and preventing the spread of fire between adjacent floors. The fire door 3 is configured to automatically close when a fire detection sensor (not shown) installed in the article conveyor equipment 100 or the like detects a fire. When the fire door 3 is closed, both the first conveyor 1 and the second conveyor 2 stop at positions that do not interfere with the fire door 3.

[0038] Here, the partition wall 5 has a cutout portion 51 formed in a region overlapping with the door movement trajectory P3, which is the movement trajectory of the fire door 3. Figure 4 As shown, the partition wall 5 includes a partition plate 50 that divides the first area A1 from the second area A2. The partition plates 50 are installed on each of the multiple layers. A pair of partition plates 50, each installed on two adjacent layers, are arranged vertically spaced apart from each other. The aforementioned cutout 51 is formed between the pair of partition plates 50 in the vertical direction. When closed, the fire door 3 is arranged to span both sides of the partition wall 5, with the cutout 51 extending through it. This allows the fire door 3 to overlap both the first and second conveyor paths P1 and P2, thus blocking the opening 40 in the target wall 4T. Consequently, the fire door 3 can be shared by both the first and second conveyor paths P1 and P2, reducing the cost and space required to install the additional fire door 3. Furthermore, when open, the fire door 3 retreats from most of the cutout 51, leaving the opening 40 open, thus opening both the first and second conveyor paths P1 and P2.

[0039] like Figures 5 to 8 As shown, a movable hood C1 is provided on the partition wall 5, and the state of the movable hood C1 changes to an overlapping state in which it is configured to overlap with the cutout portion 51 when viewed in the wall-orthogonal direction X along the wall-orthogonal direction X and a retreated state in which it retreats from the door movement trajectory P3. In this embodiment, the movable hood C1 is formed in a plate shape and is provided on the partition wall 5 in such a manner that the plate surface on the front and back sides faces the wall-orthogonal direction X. In this example, the partition wall 5 has a connecting member 52 (bracket) connecting the partition plate 50 and the movable hood C1. Moreover, the movable hood Cl is provided on the partition wall 5 by being connected to the connecting member 52. In this example, the connecting member 52 is provided in such a manner as to be adjacent to the cutout portion 51 when viewed in the wall-orthogonal direction X. In more detail, the connecting member 52 is provided at the lower end portion of the partition plate 50 in such a manner as to be adjacent above the cutout portion 51. This makes it easy to place the movable hood C1 connected to the connecting member 52 in an overlapping state with respect to the cutout portion 51 when viewed in the wall-orthogonal direction X.

[0040] The movable cover C1 is urged to be in the aforementioned overlapping state when the fire door 3 is in the open state (see Figure 6 Thus, even when the fire door 3 is open and retracted from most of the cutout 51, the movable hood C1 overlaps the cutout 51 when viewed in the wall-orthogonal direction X. Therefore, the movable hood C1 and the partition plate 50 can block the first and second areas A1 and A2, which are sandwiched between the partition wall 5. Therefore, when maintenance is performed in either the first or second area A1, A2, even if the area not undergoing maintenance is in an active state, the possibility of the hands and feet of the maintenance worker or the equipment used in maintenance jumping out of the active area through the cutout 51 can be reduced.

[0041] Furthermore, the movable cover C1 is configured so as to be pushed by the fire door 3 as the fire door 3 closes, and to be in the aforementioned retreat state (see Figure 7 and Figure 8 Thus, even if the movable hood C1 is configured to overlap the cutout portion 51 when viewed in the wall-orthogonal direction X, the movable hood C1 can be pushed open to close the fire door 3 when the fire door 3 is closed. In other words, the movable hood C1 does not hinder the closing of the fire door 3.

[0042] Thus, when the fire door 3 is in the open state, opening the opening 40, the movable hood C1 is in an overlapping state, overlapping the cutout portion 51 when viewed in the direction perpendicular to the wall X. When the fire door 3 is in the closed state, blocking the opening 40, the movable hood C1 is in a retracted state, retracted from the door movement trajectory P3 of the fire door 3. Thus, according to the article transport equipment 100, the cutout portion 51 formed in the partition wall 5 allows the fire door 3 to be positioned across both sides of the partition wall 5 in both the first area A1 and the second area A2. Furthermore, with the movable hood C1 positioned so as to overlap the cutout portion 51 when viewed in the direction perpendicular to the wall X in the aforementioned overlapping state, the two sides of the partition wall 5 can be appropriately partitioned even when the fire door 3 is in the open state.

[0043] In this embodiment, the article transport device 100 includes, in addition to the movable cover C1, an auxiliary cover C2, which is arranged to overlap the cutout portion 51 when viewed in the wall-orthogonal direction X. In this embodiment, the auxiliary cover C2 is formed in a plate shape and is installed on the partition wall 5 with the front and back surfaces of the plate facing the wall-orthogonal direction X. The auxiliary cover C2 is configured to overlap the area of ​​the cutout portion 51 that does not overlap with the movable cover C1 when viewed in the wall-orthogonal direction X. Details will be described later.

[0044] In this embodiment, the article conveying equipment 100 includes a swing support mechanism 6 that supports the movable hood C1 so that it can swing relative to the partition wall 5. In this example, the swing support mechanism 6 supports the auxiliary hood C2 in addition to the movable hood C1 so that it can swing relative to the partition wall 5. Moreover, the swing support mechanism 6 is configured to swing the movable hood C1 and the auxiliary hood C2 in directions along their respective plate surfaces. In other words, the movable hood C1 and the auxiliary hood C2, which are swung by the swing support mechanism 6, are configured to swing around a swing axis Ax along the wall-orthogonal direction X, with their respective plate surfaces facing the wall-orthogonal direction X.

[0045] In this embodiment, the swing support mechanism 6 includes a link member 61 that swings about a swing axis Ax that is perpendicular to the partition wall 5. That is, the swing support mechanism 6 is configured as a link mechanism. In this example, the swing support mechanism 6 includes a first link member 611 and a second link member 612 as the link member 61, and includes a first swing axis Ax1 and a second swing axis Ax2 as the swing axis Ax. The first swing axis Ax1 and the second swing axis Ax2 are respectively arranged along the wall-orthogonal direction X. The first link member 611 is supported by the connecting member 52 of the partition wall 5 so as to swing about the first swing axis Ax1. The second link member 612 is supported by the connecting member 52 of the partition wall 5 so as to swing about the second swing axis Ax2. Here, the second swing axis Ax2 is arranged on the second side Y2 in the door movement direction relative to the first swing axis Ax1. Furthermore, the second swing axis Ax2 is arranged above the first swing axis Ax1.

[0046] In this embodiment, the movable hood C1 is connected to the support portion 62 of the link member 61 so as to be swingable. In this example, the first link member 611 includes a first support portion 621 as the support portion 62 at a position away from the first swing axis Ax1. In addition, the first link member 611 also includes an auxiliary support portion 623 for supporting the auxiliary hood C2, but this will be described later. Moreover, the first connection portion C11 provided on the movable hood C1 is connected to the first support portion 621 so as to be swingable around the first connection axis CAx1. In addition, in this example, the second link member 612 includes a second support portion 622 as the support portion 62 at a position away from the second swing axis Ax2. Moreover, the second connection portion C12 provided on the movable hood C1 is connected to the second support portion 622 so as to be swingable around the second connection axis CAx2. In the present embodiment, the second connection axis CAx2 is arranged on the second side Y2 in the door movement direction relative to the first connection axis CAx1. In addition, the second connection axis CAx2 is arranged above the first connection axis CAx1. Moreover, the distance from the first swing axis Ax1 to the first connection axis CAx1 and the distance from the second swing axis Ax2 to the second connection axis CAx2 are set to be the same. In this example, the second connection portion C12 where the second connection axis CAx2 is arranged is arranged closer to the second side Y2 in the door movement direction than the first connection portion C11 where the first connection axis CAx1 is arranged. More specifically, the first connection portion C11 is set near the end of the movable hood C1 on the first side Y1 in the door movement direction. In addition, the second connection portion C12 is set near the end of the movable hood C1 on the second side Y2 in the door movement direction.

[0047] In this way, in the structure in which the movable hood C1 is supported by the swing support mechanism 6, the movable hood C1 is pushed by the fire door 3 from the second side Y2 in the door movement direction as the fire door 3 closes, and swings from the aforementioned overlapping state while moving toward the first side Y1 in the door movement direction and retreating from the door movement trajectory P3, thereby entering the aforementioned retreat state (see FIG. Figure 8 ). Moreover, the movable hood C1 is no longer pushed by the fire door 3 as the fire door 3 opens, and swings from the aforementioned retreat state in a manner that moves toward the second side Y2 in the door movement direction and enters the door movement trajectory P3, thereby becoming the aforementioned overlapping state (refer to Figure 6 ).

[0048] In this embodiment, the swing axis Ax of the connecting rod member 61 is arranged above the cutout portion 51. In this example, both the first swing axis Ax1 of the first connecting rod member 611 and the second swing axis Ax2 of the second connecting rod member 612 are arranged above the cutout portion 51. Moreover, the movable hood C1 is configured to enter the aforementioned overlapping state while being suspended and supported by the connecting rod member 61 (the first connecting rod member 611 and the second connecting rod member 612), and to enter the aforementioned retreat state by swinging from the overlapping state while moving toward the first side Y1 in the door movement direction. As a result, the movable hood C1 can be urged toward the aforementioned overlapping state by its own weight. Therefore, it is possible to achieve a structure in which the movable hood C1 is urged to enter the aforementioned overlapping state when the fire door 3 is open without using a force applying mechanism such as a spring.

[0049] Here, the auxiliary cover C2 is described. In this embodiment, the auxiliary cover C2 is arranged along the door movement direction Y and aligned with the movable cover C1. Figure 6 As shown, when the movable hood C1 is in the aforementioned overlapping state, the auxiliary hood C2 is arranged to be aligned with the movable hood C1 on the first side Y1 in the door moving direction.

[0050] In this embodiment, the auxiliary cover C2 is connected to the link member 61 so that as the state of the movable cover C1 changes, the auxiliary cover C2 changes to an auxiliary overlapping state in which the auxiliary cover C2 is arranged to overlap the cutout portion 51 when viewed in the wall-orthogonal direction X (see FIG. Figure 6 ), and the auxiliary retreat state of retreating from the door movement trajectory P3 which is the movement trajectory of the fire door 3 (refer to Figure 8 ). In this example, the auxiliary cover C2 is connected to the connecting member 52 together with the movable cover C1 via the first connecting rod member 611, and is provided on the partition wall 5. Here, the auxiliary cover C2 is connected to the auxiliary support portion 623 provided at a position away from the first swing axis Ax1 of the first connecting rod member 611 so as to be swingable. Moreover, the auxiliary cover C2 is connected to the auxiliary support portion 623 so as to be swingable around the third connecting axis CAx3. When the movable cover C1 is in the overlapping state, the auxiliary cover C2 becomes the auxiliary overlapping state (refer to Figure 6 ), when the movable hood C1 is in the aforementioned retreat state, it becomes the auxiliary retreat state (refer to Figure 8 ).

[0051] like Figure 6As shown, in the auxiliary overlapping state, the auxiliary cover C2 is arranged in a region closer to the first side Y1 in the door movement direction relative to the movable cover C1, and overlapping with the movement trajectory of the end edge of the movable cover C1 on the first side Y1 in the door movement direction when the movable cover C1 moves between the aforementioned overlapping state and the aforementioned retracted state, as viewed in the wall-orthogonal direction X. In the illustrated example, the auxiliary cover C2 in the auxiliary overlapping state is arranged so as to overlap with the opening region formed between the frame end 30a of the door support frame 30 and the movable cover C1 in the door movement direction Y, as viewed in the wall-orthogonal direction X.

[0052] like Figures 6 to 8 As shown, the auxiliary hood C2 changes state from the aforementioned overlapping state to the aforementioned retreat state as the movable hood C1 changes state, and swings from the auxiliary overlapping state in a manner that moves toward the second side Y2 in the door movement direction while moving upward, thereby becoming the auxiliary retreat state. In the example shown in the figure, the auxiliary hood C2 is constructed so as to change from the auxiliary overlapping state to the auxiliary retreat state by swinging upward and toward the second side Y2 in the door movement direction with the first swing axis Ax1 of the first link member 611 as the center. In this embodiment, the auxiliary hood C2 is constructed so that in the auxiliary overlapping state (refer to Figure 6 ) is at the first side Y1 closest to the door moving direction, and the state changes to the auxiliary retreat state (refer to Figure 8 ) to the first side Y1 in the door movement direction. As a result, the auxiliary cover C2 can avoid contact with the frame end 30a during the state change of the auxiliary cover C2. As a result, the auxiliary cover C2 in the auxiliary overlapping state can be configured to be close to or in contact with the frame end 30a in the door movement direction Y. Therefore, when the auxiliary cover C2 is in the auxiliary overlapping state, the gap between the auxiliary cover C2 and the frame end 30a can be minimized when viewed in the wall stop direction X, and the first area A1 and the second area A2 can be properly blocked by the partition wall 5, the movable cover C1 and the auxiliary cover C2.

[0053] The auxiliary hood C2 that shifts from the auxiliary overlapping state to the auxiliary retreating state precedes the movable hood C1 that shifts from the aforementioned overlapping state to the aforementioned retreating state, and moves along the movement trajectory of the end edge of the movable hood C1 on the first side Y1 in the door movement direction. In other words, the end edge of the movable hood C1 on the first side Y1 in the door movement direction that shifts from the aforementioned overlapping state to the aforementioned retreating state moves in a manner that follows the auxiliary hood C2 that shifts from the auxiliary overlapping state to the auxiliary retreating state. Then, as Figure 8 As shown, after the movable hood C1 is in the aforementioned retracted state and the auxiliary hood C2 is in the auxiliary retracted state, the fire door 3 abuts against the frame end 30a of the door support frame 30 from the second side Y2 in the door movement direction and is closed.

[0054] Next, the support structure of the movable cover C1 and the auxiliary cover C2 formed by the swing support mechanism 6 will be described.

[0055] As described above, the swing support mechanism 6 includes the first link member 611 and the second link member 612. The first link member 611 is swingably connected to the connection member 52 at the first swing axis Ax1. The second link member 612 is swingably connected to the connection member 52 at the second swing axis Ax2.

[0056] In this embodiment, the first link member 611 includes a first shaft support portion 611a disposed about a first swing axis Ax1, a first support portion 621 having a first connection axis CAx1, a first movable-side extension portion 611b extending from the first shaft support portion 611a (first swing axis Ax1) to the first support portion 621, an auxiliary support portion 623 having a third connection axis CAx3, and an auxiliary-side extension portion 611c extending from the first shaft support portion 611a to the auxiliary support portion 623. The first link member 611 is inserted through the first shaft support portion 611a along the first swing axis Ax1 by a shaft member. Thus, the first link member 611 is connected to the connection member 52 so as to be swingable about the first swing axis Ax1.

[0057] A first support portion 621 (support portion 62) is formed at a position of the first movable side extension portion 611b away from the first swing axis Ax1 to support the movable hood C1 in a swingable manner. The movable hood C1 is connected to the first support portion 621 so as to be swingable around the first connection axis CAx1. In this example, when the movable hood C1 is in the aforementioned overlapping state (see Figure 6 ), the first connecting axis CAx1 is arranged below the first swing axis Ax1. More specifically, the first swing axis Ax1 and the first connecting axis CAx1 are arranged so as to be aligned in the vertical direction. As a result, when the movable hood C1 is in the aforementioned overlapping state, the first movable-side extension portion 611b is arranged to extend downward from the first shaft support portion 611a. This makes it easy to arrange the movable hood C1 in a position corresponding to the cutout portion 51 arranged below the first swing axis Ax1.

[0058] An auxiliary support portion 623 is formed at a position of the auxiliary side extension portion 611c away from the first swing axis Ax1 to support the auxiliary cover C2 in a swingable manner. The auxiliary cover C2 is connected to the auxiliary support portion 623 so as to be swingable around the third connection axis CAx3. In this example, when the auxiliary cover C2 is in the auxiliary overlapping state (see Figure 6), the third connecting axis CAx3 is arranged on the first side Y1 in the door moving direction relative to the first swing axis Ax1. In more detail, the third connecting axis CAx3 and the first swing axis Ax1 are arranged in a manner aligned in the door moving direction Y. Thus, the auxiliary side extension portion 611c is arranged to extend from the first axis support portion 611a toward the first side Y1 in the door moving direction when the movable hood C1 is in the aforementioned overlapping state and the auxiliary hood C2 is in the auxiliary overlapping state. Thus, it is easy to arrange the auxiliary hood C2 in an area that is closer to the first side Y1 in the door moving direction than the movable hood C1 in the aforementioned overlapping state. In addition, in this example, the auxiliary support portion 623 of the first link component 611 is connected to the upper part of the auxiliary hood C2. Thus, the auxiliary hood C2 is arranged in a state of being suspended downward from the third connecting axis CAx3 arranged on the first side Y1 in the door moving direction relative to the first swing axis Ax1 in the auxiliary overlapping state. Therefore, in the auxiliary overlapped state of the auxiliary cover C2, the auxiliary cover C2 can be arranged on the first door moving direction side Y1 relative to the movable cover C1 in the retracted state arranged below the first swing axis Ax1.

[0059] In this embodiment, the first link member 611 is formed into a plate-like shape extending in two directions from the first swing axis Ax1. Specifically, the direction in which the first movable-side extension portion 611b extends intersects the direction in which the auxiliary-side extension portion 611c extends. In this example, these extension directions are orthogonal when viewed in the wall-orthogonal direction X. In other words, the first link member 611 is formed into an L-shape when viewed in the wall-orthogonal direction X.

[0060] In this embodiment, the second link member 612 includes a second shaft support portion 612a disposed about the second swing axis Ax2, a second support portion 622 having a second connection axis CAx2, and a second movable-side extension portion 612b extending from the second shaft support portion 612a (the second swing axis Ax2) to the second support portion 622. The second link member 612 is inserted through the second shaft support portion 612a along the second swing axis Ax2 by a shaft member. Thus, the second link member 612 is connected to the connection member 52 so as to be swingable about the second swing axis Ax2.

[0061] A second support portion 622 (support portion 62) is formed at a position of the second movable side extension portion 612b away from the second swing axis Ax2 to support the movable hood C1 in a swingable manner. The movable hood C1 is connected to the second support portion 622 so as to be swingable around the second connection axis CAx2. In this example, when the movable hood C1 is in the aforementioned overlapping state (see Figure 6), the second connecting axis CAx2 is arranged below the second swing axis Ax2. In more detail, the second swing axis Ax2 and the second connecting axis CAx2 are arranged in a manner that is aligned in the up and down directions. Thus, the second movable side extension portion 612b is arranged to extend downward from the second axis support portion 612a when the movable hood C1 is in the aforementioned overlapping state. Thus, it is easy to arrange the movable hood C1 at a position corresponding to the cutout portion 51 arranged below the second swing axis Ax2. In this embodiment, the second link member 612 is formed in the shape of a strip extending in one direction.

[0062] Next, refer to Figures 6 to 8 The operations of the movable cover C1 and the auxiliary cover C2 when the fire door 3 shifts from the open state in which the opening 40 is opened to the closed state in which the opening 40 is blocked will be described.

[0063] like Figure 6 As shown, when the fire door 3 is open, the movable hood C1 is configured to overlap with the cutout portion 51 when viewed in the direction perpendicular to the wall X, and the auxiliary hood C2 is configured to overlap with the area of ​​the cutout portion 51 that does not overlap with the movable hood C1 when viewed in the direction perpendicular to the wall X. At this time, the movable hood C1 is urged toward the aforementioned overlapping state by its own weight. Here, the movable hood C1 is substantially heavier than the auxiliary hood C2. Therefore, regardless of the gravity acting on the auxiliary hood C2, the movable hood C1 is in the aforementioned overlapping state, and thus the auxiliary hood C2 is in the auxiliary overlapping state. This eliminates the need for a force-applying mechanism such as a spring.

[0064] like Figure 7As shown, if the fire door 3 shifts to a closing position, the movable hood C1 is pushed by the fire door 3 from the second side Y2 in the door movement direction toward the first side Y1 in the door movement direction. Consequently, the first link component 611 connected to the movable hood C1 swings about the first swing axis Ax1, and the second link component 612 connected to the movable hood C1 swings about the second swing axis Ax2. As a result, the movable hood C1 swings toward the first side Y1 in the door movement direction and upward, retreating upward from the door movement trajectory P3. The configuration position of the movable hood C1 and the shape and size of the link components 61 (first link component 611, second link component 612) are set so that the movement trajectory of the end edge of the movable hood C1 on the first side Y1 in the door movement direction does not overlap with the frame end 30a of the door support frame 30. Therefore, the movable hood C1, which changes state between the aforementioned overlapping state and the aforementioned retreated state, does not contact the frame end 30a. On the other hand, the auxiliary cover C2 connected to the first link member 611 is configured so that, in the auxiliary overlapping state, it overlaps with the movement trajectory of the end edge of the movable cover C1 on the first side Y1 in the door movement direction when viewed in the wall-orthogonal direction X. Then, as the first link member 611 swings, the auxiliary cover C2 moves ahead of the movable cover C1, moving along the movement trajectory of the end edge of the movable cover C1 on the first side Y1 in the door movement direction and swinging upward away from the end region of the door movement trajectory P3 on the first side Y1 in the door movement direction.

[0065] like Figure 8 As shown, when the fire door 3 is closed, the movable hood C1 is in a retracted state, withdrawn from the door's trajectory P3. The auxiliary hood C2 is also in an auxiliary retracted state, withdrawn from the door's trajectory P3. In this embodiment, when the fire door 3 is closed, the movable hood C1 and the auxiliary hood C2 are withdrawn upward from the door's trajectory P3, being positioned above the fire door 3. The fire door 3 then abuts against the frame end 30a, sealing the opening 40 when viewed from above. This prevents the spread of fire between adjacent floors sandwiching the fire door 3 in the event of a fire.

[0066] Here, for example, when there is no longer a need to block the opening 40 by the fire door 3, the fire door 3 performs an opening operation for changing the state from the closed state to the open state. In this case, contrary to the above, the fire door 3, the movable cover C1 and the auxiliary cover C2 are opened. Figure 8 、 Figure 7 、 Figure 6 Sequential actions.

[0067] As described above, the movable hood C1 is configured to swing to the aforementioned overlapping state as the fire door 3 opens, no longer being pressed by the fire door 3, while moving from the aforementioned retracted state toward the second side Y2 in the door movement direction and toward the door movement trajectory P3. In this embodiment, the movable hood C1 descends under its own weight as the fire door 3 opens, thereby shifting from the aforementioned retracted state to the aforementioned overlapping state.

[0068] like Figure 8 As shown, in the aforementioned retracted state of the movable hood C1, the first connection axis CAx1, which is the connection portion between the movable hood C1 and the first link member 611, is located closer to the first side Y1 in the door movement direction than the first swing axis Ax1, which is the swing center of the first link member 611. Similarly, the second connection axis CAx2, which is the connection portion between the movable hood C1 and the second link member 612, is located closer to the first side Y1 in the door movement direction than the second swing axis Ax2, which is the swing center of the second link member 612. Therefore, in the aforementioned retracted state of the movable hood C1 (the fire door 3 is closed), the movable hood C1, which is suspended and supported by the first link member 611 and the second link member 612, is biased by its own weight to swing downward (clockwise in the illustrated example). Therefore, as the fire door 3 opens, the movable hood C1 becomes unsupported by the fire door 3 and swings downward under its own weight. This places the movable hood C1 in the aforementioned overlapping position. Furthermore, the first link member 611 supports the auxiliary hood C2 on the auxiliary support portion 623 in addition to the movable hood C1. Therefore, as the movable hood C1 descends as the fire door 3 opens, the auxiliary hood C2 also descends, entering the auxiliary overlapping position.

[0069] [Other Implementation Methods]

[0070] Next, other embodiments of the article transport facility will be described.

[0071] (1) In the above embodiment, the swing support mechanism 6 is described as including the first link member 611 and the second link member 612 as the link member 61 for swingably supporting the movable hood C1. However, the present invention is not limited to this example, and the swing support mechanism 6 may also include only one of the first link member 611 and the second link member 612. In this case, the location where the movable hood C1 is supported by the first link member 611 or the second link member 612 can be appropriately selected to provide a location suitable for supporting the movable hood C1 in a well-balanced manner.

[0072] (2) In the above embodiment, the first link member 611 is formed into an elongated plate shape extending in two directions (L-shaped when viewed in the direction perpendicular to the wall X), and the second link member 612 is formed into an elongated plate shape extending in one direction. However, the present invention is not limited to this example, and the shapes of the first link member 611 and the second link member 612 may be appropriately changed to rectangular, polygonal, circular, elliptical, etc. when viewed in the direction perpendicular to the wall X.

[0073] (3) In the above embodiment, the swing support mechanism 6 that supports the movable hood C1 so as to be swingable relative to the partition wall 5 is described as a link mechanism having the link member 61. However, the present invention is not limited to such an example, and the swing support mechanism 6 may be configured as follows. Figure 9 It is constructed as a hinge mechanism as shown. The swing support mechanism 6 in this case may also have a hinge portion 63, which connects the connecting part 52 of the partition wall 5 to the movable hood C1, and supports the plate-shaped movable hood C1 so that it can swing in a direction perpendicular to its plate surface. In addition, the door movement direction Y in this case is preferably set to be along the wall orthogonal direction X that is perpendicular to the partition wall 5. Even with such a structure, the movable hood C1 is pushed by the fire door 3 as the fire door 3 closes, and is put into a retreat state that retreats from the door movement trajectory P3. Then, the movable hood C1 is no longer pushed by the fire door 3 as the fire door 3 opens, and swings in a manner that enters the door movement trajectory P3 from the aforementioned retreat state by virtue of its own weight, thereby becoming the aforementioned overlapping state.

[0074] (4) In the above embodiment, an example is described in which the movable hood C1 is swung by the swing support mechanism 6 to change the state between the aforementioned overlapping state and the aforementioned retreat state. However, the present invention is not limited to such an example, and the movable hood C1 may be changed between the aforementioned overlapping state and the aforementioned retreat state without using the swing support mechanism 6. For example, Figure 10In the example shown, the movable hood C1 is supported by the connecting member 52 while being allowed to move only in the vertical direction. The end surface on the second side Y2 in the door movement direction has a hood inclined surface C1a that tilts upward as it approaches the second side Y2 in the door movement direction. Furthermore, the end surface on the first side Y1 in the door movement direction of the fire door 3 has a door inclined surface 3a that tilts upward as it approaches the second side Y2 in the door movement direction. Furthermore, as the fire door 3 closes, the hood inclined surface C1a is pushed by the door inclined surface 3a from the second side Y2 in the door movement direction toward the first side Y1 in the door movement direction, exerting an upward force on the hood inclined surface C1a, causing the hood inclined surface C1a to move upward along the door inclined surface 3a. As a result, the movable hood C1 retreats upward from the door movement trajectory P3, entering the aforementioned retreated state. Furthermore, the movable hood C1 is no longer pressed by the fire door 3 as the fire door 3 opens, and moves from the aforementioned retreat state toward the door movement trajectory P3 by its own weight, thereby reaching the aforementioned overlapped state.

[0075] (5) In the above embodiment, the article transport facility 100 is described as including the auxiliary cover C2 in addition to the movable cover C1. However, the present invention is not limited to this example, and the article transport facility 100 may not include the auxiliary cover C2.

[0076] (6) In the above-mentioned embodiment, an example in which the target wall 4T having the opening 40 through which both the first conveying path P1 and the second conveying path P2 pass is the floor portion 4 of the equipment, that is, an example in which the target wall 4T is arranged along the horizontal direction is described. However, the present invention is not limited to such an example, and the target wall 4T may also be a wall arranged along the vertical direction. For example, the target wall 4T may also be a vertical wall of a fire protection zone set in a plurality of arrangements on the same floor within the facility. In this case, the first conveying path P1 and the second conveying path P2 are set along the horizontal direction. In addition, the target wall 4T may also be a wall arranged in a direction inclined relative to the horizontal direction and the vertical direction.

[0077] (7) In the above embodiment, an example is described in which the surrounding wall 96 is provided to surround the first transport path P1 and the second transport path P2 in the transport direction. However, such a surrounding wall 96 may not be provided.

[0078] (8) In the above embodiment, the movable hood C1 is biased toward the overlapped state by its own weight. However, the present invention is not limited thereto. The movable hood C1 may be biased toward the overlapped state by the force of an elastic member such as a spring.

[0079] (9) In addition, the structure disclosed in the above-mentioned embodiment can also be combined with the structure disclosed in other embodiments and applied as long as there is no contradiction. Regarding other structures, the embodiment disclosed in this specification is merely an example in all aspects. Therefore, various modifications can be made as appropriate within the scope of the present disclosure.

[0080] [Overview of the above embodiment]

[0081] Next, the article transport facility described above will be described.

[0082] The article conveying equipment includes a first conveying path and a second conveying path arranged parallel to each other along a conveying direction in which articles are conveyed, a first conveying device moving along the first conveying path, and a second conveying device moving along the second conveying path, comprising: a partition wall separating the first conveying path and the second conveying path along the conveying direction; an object wall arranged so as to intersect the conveying direction; an opening penetrating the object wall in the conveying direction and allowing both the first conveying path and the second conveying path to pass through; and a fire door moving parallel to an opening surface of the opening and changing its state between a closed state in which the opening is blocked and an open state in which the opening is opened and both the first conveying path and the second conveying path are open. ; A cutout portion is formed in the aforementioned partition wall in an area overlapping with the door movement trajectory serving as the movement trajectory of the aforementioned fire door; the aforementioned fire door is arranged across both sides of the aforementioned partition wall in a state of penetrating the aforementioned cutout portion in the aforementioned closed state; a direction orthogonal to the aforementioned partition wall is set as a wall-orthogonal direction, and a movable hood is provided on the aforementioned partition wall, and the state of the movable hood changes to an overlapping state in which it is arranged to overlap with the aforementioned cutout portion when viewed along the wall-orthogonal direction of the aforementioned wall, and a retreat state in which it retreats from the aforementioned door movement trajectory; the aforementioned movable hood is forced to become the aforementioned overlapping state in the aforementioned open state of the aforementioned fire door, and becomes the aforementioned retreat state as it is pushed by the aforementioned fire door in the closing action used to change the state of the aforementioned fire door from the aforementioned open state to the aforementioned closed state.

[0083] According to this structure, since a cutout is formed in the area of ​​the partition wall that overlaps with the door's trajectory, a fire door can be placed across both sides of the partition wall. When the fire door is closed, the fire door can be placed so that it overlaps both the first and second conveyor paths, thereby blocking the opening in the target wall. Thus, the fire door can be shared by both the first and second conveyor paths, reducing the cost and installation space associated with the increased number of fire doors. Furthermore, when the fire door is closed, the movable hood installed in the partition wall is pushed by the closing fire door, retreating from the door's trajectory. On the other hand, when the fire door is open, opening both the first and second conveyor paths, the movable hood is placed in an overlapping position, overlapping the cutout when viewed orthogonally to the wall. Therefore, the overlapping movable hood can block the area on the side of the partition wall where the first conveyor path is located and the area on the side where the second conveyor path is located. Therefore, according to this structure, the fire door can be arranged across both sides of the partition wall by means of a cutout formed in the partition wall, and the two sides of the partition wall can be appropriately separated by means of a movable hood that is arranged in an overlapping state to overlap relative to the cutout when viewed in a direction orthogonal to the wall.

[0084] Here, it is preferred that the direction of movement of the fire door is set as the door movement direction, the side of the fire door moved by means of the closing action is set as the first side of the door movement direction, and the side of the fire door moved by means of the opening action for changing the state from the closed state to the open state is set as the second side of the door movement direction; a swing support mechanism is also provided, which supports the movable hood so as to be swingable relative to the partition wall; the movable hood is pushed by the fire door from the second side of the door movement direction as the fire door closes, and is swung from the overlapping state in a manner of moving toward the first side of the door movement direction while retreating from the door movement trajectory, thereby becoming the retreat state, and is no longer pushed by the fire door as the fire door opens, and is swung from the retreat state in a manner of moving toward the second side of the door movement direction while entering the door movement trajectory, thereby becoming the overlapping state.

[0085] According to this structure, the closing action of the fire door pushes the movable hood, causing it to swing to the retracted state. When the fire door opens, the movable hood is no longer pressed by the fire door, causing it to swing in the opposite direction to the overlapped state. Thus, with a simple structure that simply supports the movable hood so that it can swing relative to the partition wall using a swing support mechanism, it is possible to achieve a movable hood that changes between the overlapped state and the retracted state in response to the movement of the fire door.

[0086] In addition, in a structure having a swing support mechanism, it is preferred that the door movement direction is along the direction of the object wall; the swing support mechanism has a connecting rod component, which swings around a swing axis orthogonal to the partition wall; the movable hood is swingably connected to a support portion of the connecting rod component that is separated from the swing axis; the swing axis of the connecting rod component is arranged above the cutout portion; the movable hood becomes the overlapping state in a state of being suspended and supported by the connecting rod component, and swings from the overlapping state in a manner of moving toward the first side of the door movement direction while moving upward, to become the retreat state.

[0087] According to this structure, the movable hood can be urged to the overlapping state by its own weight. Therefore, it is possible to realize a structure in which the movable hood is urged to the overlapping state when the fire door is open without using an urging mechanism such as a spring.

[0088] In addition, in the structure in which the swing support mechanism has a connecting rod component, it is preferred that an auxiliary cover is also provided, which is arranged along the door movement direction with the movable hood; the auxiliary cover is connected to the connecting rod component so that as the state of the movable hood changes, the state of the auxiliary cover changes to an auxiliary overlapping state in which it is arranged to overlap with the cutout portion when viewed in a direction perpendicular to the wall, and an auxiliary retreat state in which it retreats from the door movement trajectory; in the auxiliary overlapping state, the auxiliary cover is arranged in an area that is close to the first side of the door movement direction relative to the movable hood and overlaps with the movement trajectory of the end edge of the movable hood on the first side of the door movement direction when the movable hood moves between the overlapping state and the retreat state when viewed in a direction perpendicular to the wall; as the movable hood changes its state from the overlapping state to the retreat state, the auxiliary cover swings from the auxiliary overlapping state in a manner that moves toward the second side of the door movement direction while moving upward, and becomes the auxiliary retreat state.

[0089] In the case of a structure in which the movable hood is swung in a manner that moves toward the first side of the door movement direction while moving upward in order to move from an overlapping state to a retreat state, the movable hood needs to have room to move toward the first side of the door movement direction. Therefore, when the movable hood is in an overlapping state, it is difficult to arrange the movable hood so that it overlaps with the entire cutout portion when viewed in a direction perpendicular to the wall. In this case, even if the movable hood is in an overlapping state, a gap not covered by the movable hood occurs in the end area of ​​the cutout portion on the first side of the door movement direction when viewed in a direction perpendicular to the wall. However, according to this structure, an auxiliary hood can be arranged in an area that is close to the first side of the door movement direction relative to the movable hood and overlaps the movement trajectory of the end edge of the movable hood on the first side of the door movement direction when viewed in a direction perpendicular to the wall. This makes it possible to more appropriately block the area on the side of the partition wall where the first conveying path is arranged and the area on the side where the second conveying path is arranged. In addition, the auxiliary hood is linked to the movable hood, and when the movable hood is in a retreat state, it is arranged in an auxiliary retreat state that retreats from the door movement trajectory. Therefore, even with the present structure including the auxiliary cover, the auxiliary cover does not hinder the movement of the fire door.

[0090] Furthermore, preferably, the first conveying device and the second conveying device are configured to convey articles in a vertical direction across multiple layers; the target wall is a floor portion of a facility; and the fire door moves along the floor portion.

[0091] The article transport facility described above is suitable for such a facility that includes a transport process for transporting articles across multiple layers by penetrating the floor portions of each layer.

[0092] Furthermore, it is preferable that a surrounding wall is provided to surround the first conveyance path and the second conveyance path along the conveyance direction.

[0093] According to this structure, the space where the first and second conveying paths are arranged can be blocked from the outside by the surrounding wall. Therefore, it is possible to prevent an operator from accidentally entering the space where the first and second conveying paths are arranged while the first and second conveying devices are operating.
