Description

TECHNICAL FIELD The present invention relates to an article conveying facility including a conveying device for conveying articles and a fire door.

For example, in Japanese Patent No. 6304057 (Patent Document 1), an article conveying apparatus (2 ) is disclosed. The article conveying facility is provided with a fire door (34) which normally opens the opening (f) and closes the opening (f) when a fire occurs. It should be noted that the reference numerals shown in parentheses in the above are those of Patent Document 1.

Japanese Patent No. 6304057

From the viewpoint of improving the efficiency of conveying articles in an article conveying facility provided with an article conveying apparatus as described above, for example, two article conveying apparatuses are arranged side by side to increase the amount that can be conveyed. can be considered. In this case, maintenance of the article conveying apparatus may be necessary, but by using a partition wall to separate the two article conveying apparatuses so that maintenance can be performed on each of the two article conveying apparatuses, the maintenance of one article conveying apparatus can be minimized. Even when the other article conveying apparatus is in operation, the safety of the operator who performs maintenance can be ensured.

By the way, when the article conveying apparatus is installed across fireproof compartments such as floors and walls, the opening provided in the floor or wall through which the article conveying apparatus passes can be closed in the event of a fire. fire doors should be installed in In the case where two article conveying devices are provided as described above, the area where one article conveying device is provided and the area where the other article conveying device is provided with a partition wall are each provided with a fire prevention device. It is conceivable to provide a door. However, an increase in the number of fire doors to be installed leads to an increase in cost and installation space. On the other hand, it is also conceivable to use one fire door, provide a notch portion penetrating both areas in a part of the partition wall, and arrange the fire door so as to straddle both areas.

However, when the fire door is shared by both areas in this way, when the fire door is in an open state, the notch provided in the partition wall is in an open state. If the cutout is in such a state, when maintenance is being performed in one area, there is a possibility that the hands and feet of a worker or equipment used for maintenance may jump out through the cutout into the other area. Therefore, the article conveying apparatus cannot be operated in the other area.

In view of the above-mentioned actual situation, in an article conveying facility having a partition wall that partitions two article conveying devices along a conveying path, fire doors are arranged across both sides of the partition wall, and both sides of the partition wall are appropriately partitioned. Realization of a technology that enables this is desired.

A first conveying path and a second conveying path arranged parallel to each other along a conveying direction in which an article is conveyed, a first conveying device moving along the first conveying path, and along the second conveying path and a second conveying device that moves by
a partition wall separating the first transport path and the second transport path along the transport direction;
a target wall arranged to intersect the conveying direction;
an opening that penetrates the target wall in the transport direction and through which both the first transport path and the second transport path pass;
A state change between a closed state in which the opening is closed by moving parallel to the opening surface of the opening and an open state in which the opening is opened to open both the first conveying path and the second conveying path. a fire door for
A notch portion is formed in the partition wall in a region overlapping a door movement trajectory, which is a movement trajectory of the fire door,
The fire door is arranged on both sides of the partition wall in a state of penetrating the notch in the closed state,
A direction orthogonal to the partition wall is defined as a wall orthogonal direction, and the partition wall includes an overlapping state in which the partition wall overlaps the notch when viewed in the wall orthogonal direction along the wall orthogonal direction, and the door movement trajectory. A movable cover is provided that changes its state to a retracted state that retracts from
The movable cover is biased so as to be in the overlapping state in the open state of the fire door, and moves toward the fire door in accordance with a closing operation for changing the state of the fire door from the open state to the closed state. is pushed to the retracted state ,

The movable cover changes its state between the overlapping state and the retracted state while maintaining the posture in which the plate surface is oriented in the direction perpendicular to the wall.

According to this configuration, since the cutout portion is formed in the region overlapping the door movement locus in the partition wall, the fire door can be arranged across both sides of the partition wall, and when the fire door is closed, A fire door can be arranged so as to overlap both the first transport path and the second transport path to close the opening of the target wall. Therefore, the fire door can be shared by the first transport route and the second transport route, and an increase in cost and installation space due to an increase in the number of installed fire doors can be suppressed. In the closed state of the fire door, the movable cover provided on the partition wall is pushed by the closing fire door to be in a retracted state in which the movable cover is retracted from the door movement trajectory. On the other hand, in the open state in which the fire door opens both the first transport path and the second transport path, the movable cover is in an overlapping state in which it is arranged so as to overlap the notch portion when viewed in the direction perpendicular to the wall. Therefore, the overlapped movable cover can block the area on the side where the first transport path is arranged and the area on the side where the second transport path is arranged across the partition wall. Therefore, according to this configuration, the notch formed in the partition wall allows the fire door to be arranged across both sides of the partition wall, and in the overlapped state, the notch can be seen in the direction orthogonal to the wall. Movable covers arranged so as to overlap make it possible to properly partition both sides of the partition wall.

For example, the second transfer section 24 is configured using a horizontal articulated arm. In the illustrated example, a pair of second transfer sections 24 are vertically aligned and supported by the same second lifting body 23 . Thus, in this embodiment, the first conveying device 1 and the second conveying device 2 have the same structure.

The article conveying facility 100 has an opening 40 that passes through the target wall 4T in the conveying direction and through which both the first conveying path P1 and the second conveying path P2 pass. In the example shown in FIG. 1, an opening 40 is formed in each of the floors 4 on the second and third floors, which are the target walls 4T. The opening 40 is formed so as to vertically penetrate each of these floors 4 . Both the first guide rail 11 and the second guide rail 21 are inserted through the opening 40 . The opening 40 is formed larger than the total area of the first transport device 1 and the second transport device 2 in plan view. The first conveying device 1 and the second conveying device 2 travel between floors through the opening 40 .

The article conveying equipment 100 moves parallel to the opening surface of the opening 40, and has a closed state in which the opening 40 is closed, and an open state in which the opening 40 is opened to open both the first conveying path P1 and the second conveying path P2. It is equipped with a fire door 3 that changes its state to and from. Fire door 3 is configured to move along floor 4 . That is, in this example, the door moving direction Y, which is the moving direction of the fire door 3, is the direction along the target wall 4T (floor portion 4) arranged perpendicular to the partition wall 5. As shown in FIG. In this embodiment, the door moving direction Y is a direction orthogonal to the wall orthogonal direction X. As shown in FIG. In the illustrated example, the fire door 3 is supported by a door support frame 30 installed on the target wall 4T and is guided by the door support frame 30 to move along the door moving direction Y.
As shown in FIG. 8, in the closed state, the fire door 3 abuts on the frame end portion 30a of the door support frame 30 arranged to face the fire door 3 in the door moving direction Y. As shown in FIG. The fire door 3 closes the opening 40 in plan view by coming into contact with the frame end portion 30a in the closed state. Below, in the door moving direction Y, the side to which the fire door 3 moves due to the closing operation for changing the state from the open state to the closed state is defined as the first side Y1 in the door moving direction, and the fire door 3 changes from the closed state to the open state. The side moved by the opening operation for changing the state is defined as the second side Y2 in the door moving direction.

2 to 6 show the case where the fire door 3 is open. The fire door 3 is open while the first conveying device 1 and the second conveying device 2 are in operation. Also, for example, when maintenance is performed in at least one of the first area A1 and the second area A2, the fire door 3 is opened. In this embodiment, the article conveying facility 100 is provided with a first workbench 91 and a second workbench 92 that can be arranged in such a manner as to partially cover the opening 40 . The first workbench 91 is configured to cover a portion of the opening 40 in the first area A1 in the unfolded state, and the second workbench 92 is configured to cover the opening 40 in the second area A2 in the unfolded state. is configured to cover part of the The first workbench 91 and the second workbench 92 can be used as footholds for workers during maintenance, and can be folded and stored when maintenance is not performed. In this figure, the first workbench 91 and the second workbench 92 are shown folded and stored. Also, in the illustrated example, 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 detachably provided, and can be removed when maintenance is not performed. Furthermore, in this embodiment, a plurality of emergency stop switches S for stopping the operation of the first conveying device 1 or the second conveying device 2 are provided. The emergency stop switch S is used as needed by a maintenance worker or the like. In the illustrated example, emergency stop switches S are provided at a plurality of locations inside and outside the surrounding wall 96 . As a result, an operator or the like can press the emergency stop switch S from both the inside and the outside of the surrounding wall 96 .

FIG. 8 shows the case where the fire door 3 is closed. When a fire occurs, the fire door 3 closes the opening 40 and suppresses the spread of fire between adjacent floors. The fire door 3 is configured to automatically close when a fire detection sensor (not shown) provided in the article transport equipment 100 or the like detects a fire. When the fire door 3 is closed, both the first transfer device 1 and the second transfer device 2 stop at positions where they do not interfere with the fire door 3 .

Here, a notch 51 is formed in the partition wall 5 in a region overlapping the door movement locus P3, which is the locus of movement of the fire door 3 . In this embodiment, as shown in FIG. 4, the partition wall 5 includes a partition plate 50 that partitions the first area A1 and the second area A2. The partition plate 50 is provided on each of the multiple floors. A pair of partition plates 50 provided on each of two adjacent floors are arranged apart from each other in the vertical direction. The notch 51 described above is formed between the pair of partition plates 50 in the vertical direction. The fire doors 3 are arranged on both sides of the partition wall 5 so as to pass through the cutouts 51 in the closed state. Thereby, in the closed state of the fire door 3, the fire door 3 can be arranged so as to overlap both the first transport path P1 and the second transport path P2, and close the opening 40 of the target wall 4T. Therefore, the fire door 3 can be shared by the first transport path P1 and the second transport path P2, and an increase in cost and installation space due to an increase in the number of fire doors 3 to be installed can be suppressed. In the open state, the fire door 3 retracts from most of the notch 51 and opens the opening 40 to open both the first conveying path P1 and the second conveying path P2.

As shown in FIGS. 5 to 8, the partition wall 5 has an overlapping state in which it overlaps with the cutout portion 51 when viewed in the wall orthogonal direction X along the wall orthogonal direction X, and a state in which the door is retracted from the door movement locus P3. A movable cover C1 is provided that changes its state to a retracted state. In this embodiment, the movable cover C1 is formed in a plate shape, and is provided on the partition wall 5 so that the front and back plate surfaces face the wall orthogonal direction X. As shown in FIG. In this example, the partition wall 5 includes a connecting member 52 (bracket) that connects the partition plate 50 and the movable cover C1. The movable cover C<b>1 is provided on the partition wall 5 by being connected to the connecting member 52 . In this example, the connecting member 52 is provided so as to be adjacent to the notch 51 in the wall orthogonal direction X view. provided at the lower end of the As a result, the movable cover C<b>1 connected to the connecting member 52 is configured to easily overlap the notch 51 in the wall orthogonal direction X view.

The movable cover C1 is biased so as to overlap when the fire door 3 is open (see FIG. 6). As a result, even when the fire door 3 is retracted from most of the notch 51 in the open state, the movable cover C1 overlaps the notch 51 as viewed in the wall orthogonal direction X. Therefore, the first area A1 and the second area A2 sandwiching the partition wall 5 can be cut off by the movable cover C1 and the partition plate 50 . Therefore, when maintenance is being performed in one of the first area A1 and the second area A2, even if the area in which maintenance is not being performed is set to the operating state, the area in the operating state is subject to maintenance work. It is possible to reduce the possibility that a person's hands and feet, equipment used for maintenance, etc., may protrude through the notch portion 51 .

Further, the movable cover C1 is configured so as to be pushed by the fire door 3 as the fire door 3 is closed (see FIGS. 7 and 8). As a result, even in a configuration in which the movable cover C1 is provided so as to overlap the cutout portion 51 when viewed in the wall orthogonal direction X, the movable cover C1 is pushed aside when the fire door 3 is to be closed. The fire door 3 can be caused to perform a closing action. That is, the movable cover C<b>1 does not interfere with the closing operation of the fire door 3 .

In this way, the movable cover C1 overlaps the notch 51 in the wall orthogonal direction X view when the fire door 3 opens the opening 40, and when the fire door 3 closes the opening 40, the fire door C1 overlaps the notch 51. 3, the retracted state of retracting from the door movement locus P3. Therefore, according to the article transport equipment 100, the fire doors 3 can be arranged in both the first area A1 and the second area A2 across both sides of the partition wall 5 by the notch 51 formed in the partition wall 5. Moreover, even when the fire door 3 is open, both sides of the partition wall 5 can be covered by the movable cover C1 arranged so as to overlap with the notch 51 in the wall orthogonal direction X view in the overlapping state. It is possible to partition appropriately.

In this embodiment, in addition to the movable cover C1, the article transport facility 100 includes an auxiliary cover C2 that overlaps the notch 51 when viewed in the wall orthogonal direction X. As shown in FIG. In this embodiment, the auxiliary cover C2 is formed in a plate shape, and is provided on the partition wall 5 so that the front and back plate surfaces face the wall orthogonal direction X. As shown in FIG. The auxiliary cover C2 is configured to overlap a region of the cutout portion 51 that does not overlap with the movable cover C1 when viewed in the wall orthogonal direction X. As shown in FIG. Details will be described later.

In this embodiment, the article transport facility 100 includes a swing support mechanism 6 that swingably supports the movable cover C<b>1 with respect to the partition wall 5 . In this example, the swing support mechanism 6 supports the auxiliary cover C2 swingably with respect to the partition wall 5 in addition to the movable cover C1. The rocking support mechanism 6 is configured to rock the movable cover C1 and the auxiliary cover C2 in directions along their respective plate surfaces. In other words, the movable cover C1 and the auxiliary cover C2 that are rocked by the rocking support mechanism 6 are in a state in which each plate surface faces the wall orthogonal direction X around the rocking axis Ax along the wall orthogonal direction X. is configured to oscillate at

In this embodiment, the rocking support mechanism 6 includes a link member 61 that rocks around a rocking axis Ax 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 a first swing axis Ax1 and a second swing axis Ax as the swing axis Ax. and a driving axis Ax2. The first swing axis Ax1 and the second swing axis Ax2 are arranged along the wall orthogonal direction X, respectively. 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 moving direction from the first swing axis Ax1. Further, the second swing axis Ax2 is arranged above the first swing axis Ax1.

In this embodiment, the movable cover C<b>1 is pivotably connected to the support portion 62 which is spaced apart from the pivot axis Ax of the link member 61 . In this example, the first link member 611 includes a first support portion 621 as the support portion 62 at a position spaced apart from the first swing axis Ax1. The first link member 611 also includes an auxiliary support portion 623 that supports the auxiliary cover C2, which will be described later. A first connecting portion C11 provided on the movable cover C1 is connected to the first supporting portion 621 so as to be capable of swinging about the first connecting axis CAx1. Further, in this example, the second link member 612 includes a second support portion 622 as the support portion 62 at a position spaced apart from the second swing axis Ax2. A second connecting portion C12 provided on the movable cover C1 is connected to the second supporting portion 622 so as to be capable of swinging about the second connecting axis CAx2. In this embodiment, the second connection axis CAx2 is arranged on the second side Y2 in the door movement direction with respect to the first connection axis CAx1. In addition, the second connection axis CAx2 is arranged above the first connection axis CAx1. 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 connecting portion C12 where the second connecting axis CAx2 is arranged is arranged on the second side Y2 in the door movement direction relative to the first connecting portion C11 where the first connecting axis CAx1 is arranged. . More specifically, the first connecting portion C11 is set near the end of the movable cover C1 on the first side Y1 in the door moving direction. Further, the second connecting portion C12 is set near the end portion of the movable cover C1 on the second side Y2 in the door moving direction.

In this structure in which the movable cover C1 is supported by the swing support mechanism 6, the movable cover C1 is pushed by the fire door 3 from the second side Y2 in the door movement direction as the fire door 3 closes. From the overlapped state, the door moves toward the first side Y1 in the door moving direction and swings away from the door moving locus P3 to enter the retracted state (see FIG. 8). As the fire door 3 is opened, the movable cover C1 is no longer pushed by the fire door 3, so that the movable cover C1 is moved from the retracted state to the second side Y2 in the door movement direction and is swung so as to enter the door movement path P3. move to a duplicate state (see FIG. 6).

In this embodiment, the swing axis Ax of the link member 61 is arranged above the notch 51 . In this example, both the first swing axis Ax1 of the first link member 611 and the second swing axis Ax2 of the second link member 612 are arranged above the notch 51 . The movable cover C1 is suspended and supported by the link member 61 (the first link member 611 and the second link member 612) and becomes an overlapping state. It is configured to swing upward to be in a retracted state. As a result, the movable cover C1 can be biased into the overlapping state by its own weight. Therefore, without using an urging mechanism such as a spring, for example, it is possible to realize a configuration in which the movable cover C1 is urged so as to overlap when the fire door 3 is open.

Here, a description of the auxiliary cover C2 is added. In this embodiment, the auxiliary cover C2 is arranged along the door moving direction Y along with the movable cover C1. Specifically, as shown in FIG. 6, when the movable cover C1 is in the overlapping state, the auxiliary cover C2 is arranged side by side with respect to the movable cover C1 on the first side Y1 in the door moving direction.

In this embodiment, the auxiliary cover C2 is disposed so as to overlap the notch 51 when viewed in the wall orthogonal direction X (see FIG. 6) and the fire door It is connected to the link member 61 so as to change the state to an auxiliary retracted state (see FIG. 8) in which it is retracted from the door movement locus P3, which is the movement locus of No. 3. In this example, the auxiliary cover C2 is provided on the partition wall 5 by being connected to the connecting member 52 through the first link member 611 together with the movable cover C1. Here, the auxiliary cover C2 is pivotably connected to an auxiliary support portion 623 provided at a position spaced apart from the first pivot axis Ax1 in the first link member 611. As shown in FIG. The auxiliary cover C2 is connected to the auxiliary support portion 623 so as to be swingable about the third connection axis CAx3. The auxiliary cover C2 is in the auxiliary overlapping state when the movable cover C1 is in the overlapping state (see FIG. 6), and is in the auxiliary retracted state when the movable cover C1 is in the retracted state (see FIG. 8).

As shown in FIG. 6, in the auxiliary overlapping state, the auxiliary cover C2 is located on the first side Y1 in the door movement direction with respect to the movable cover C1, and when viewed in the wall orthogonal direction X, the movable cover C1 is in the overlapping state and the retracted state. The movable cover C1 is arranged in a region that overlaps with the movement locus of the edge of the door moving direction first side Y1 when moving between and. In the illustrated example, the auxiliary cover C2 in the auxiliary overlapping state overlaps the opening area formed between the frame end portion 30a of the door support frame 30 and the movable cover C1 in the door movement direction Y when viewed in the wall orthogonal direction X. are arranged to

As shown in FIGS. 6 to 8, as the movable cover C1 changes from the overlapping state to the retracted state, the auxiliary cover C2 moves upward from the auxiliary overlapping state toward the second side Y2 in the door moving direction. It rocks to move and becomes an auxiliary retraction state. In the illustrated example, the auxiliary cover C2 swings upward about the first swing axis Ax1 of the first link member 611 and toward the second side Y2 in the door moving direction, thereby switching from the auxiliary overlapping state to the auxiliary retracted state. is configured to be In this embodiment, the auxiliary cover C2 is positioned closest to the first side Y1 in the door movement direction in the auxiliary overlapping state (see FIG. 6), and the auxiliary cover C2 is in the auxiliary retracted state (see FIG. 8). It is configured so as not to be displaced on the moving direction first side Y1. As a result, it is possible to prevent the auxiliary cover C2 from coming into contact with the frame end portion 30a while the state of the auxiliary cover C2 is changing. Therefore, the auxiliary cover C2 in the auxiliary overlapping state can be arranged so as to be close to the frame end portion 30a in the door moving direction Y or to be in contact therewith. Therefore, when the auxiliary cover C2 is in the auxiliary overlapping state, the gap between the auxiliary cover C2 and the frame end portion 30a can be minimized when viewed in the wall orthogonal direction X, and the partition wall 5, the movable cover C1, and the auxiliary cover C2 form the first area A1. and the second area A2 can be properly blocked.

The auxiliary cover C2 transitioning from the auxiliary overlapping state to the auxiliary retracted state follows the moving locus of the edge of the movable cover C1 on the first side Y1 in the door movement direction, ahead of the movable cover C1 transitioning from the overlapping state to the retracted state. Moving. In other words, the edge of the movable cover C1 moving from the overlapping state to the retracted state on the first side Y1 in the door moving direction moves so as to follow the auxiliary cover C2 moving from the auxiliary overlapping state to the auxiliary retracted state. Then, as shown in FIG. 8, after the movable cover C1 is in the retracted state and the auxiliary cover C2 is in the auxiliary retracted state, the fire door 3 moves toward the frame end 30a of the door support frame 30 in the door moving direction. It contacts from the second side Y2 and becomes a closed state.

Next, a support structure for the movable cover C1 and the auxiliary cover C2 by the swing support mechanism 6 will be described.

As described above, the swing support mechanism 6 has the first link member 611 and the second link member 612 . The first link member 611 is swingably connected to the connecting member 52 at the first swing axis Ax1. The second link member 612 is swingably connected to the connecting member 52 at the second swing axis Ax2.

In the present embodiment, the first link member 611 includes a first shaft support portion 611a arranged on the first swing axis Ax1, a first support portion 621 provided with the first connection axis CAx1, a first shaft A first movable side extension portion 611b extending from a support portion 611a (first swing axis Ax1) to a first support portion 621; an auxiliary support portion 623 provided with a third connection axis CAx3; and an auxiliary side extension portion 611c extending from the support portion 611a to the auxiliary support portion 623. The first link member 611 is inserted through the shaft member along the first swing axis Ax1 at the first shaft support portion 611a. Thereby, the first link member 611 is connected to the connecting member 52 so as to be able to swing about the first swing axis Ax1.

A first support portion 621 (support portion 62) that swingably supports the movable cover C1 is formed at a position apart from the first swing axis Ax1 in the first movable side extension portion 611b. The movable cover C1 is connected to the first support portion 621 so as to be swingable about the first connection axis CAx1. In this example, when the movable cover C1 is in the overlapping state (see FIG. 6), the first connection axis CAx1 is arranged below the first swing axis Ax1. More specifically, the first swing axis Ax1 and the first connection axis CAx1 are arranged vertically side by side. Therefore, the first movable-side extension portion 611b is arranged to extend downward from the first shaft support portion 611a when the movable cover C1 is in the overlapping state. This makes it easy to dispose the movable cover C1 at a position corresponding to the notch 51 disposed below the first swing axis Ax1.

An auxiliary support portion 623 that rockably supports the auxiliary cover C2 is formed at a position spaced apart from the first swing axis Ax1 in the auxiliary side extension portion 611c. The auxiliary cover C2 is connected to the auxiliary support portion 623 so as to be able to swing about the third connection axis CAx3. In this example, when the auxiliary cover C2 is in the auxiliary overlapping state (see FIG. 6), the third connecting axis CAx3 is arranged on the first side Y1 in the door movement direction with respect to the first swing axis Ax1. More specifically, the third connection axis CAx3 and the first swing axis Ax1 are arranged so as to be aligned in the door moving direction Y. As shown in FIG.
Therefore, when the movable cover C1 is in the overlapping state and the auxiliary cover C2 is in the auxiliary overlapping state, the auxiliary side extending portion 611c extends from the first shaft support portion 611a toward the first side Y1 in the door movement direction. are arranged as follows. This makes it easier to dispose the auxiliary cover C2 in the area on the first side Y1 in the door moving direction than the overlapping movable cover C1. In this example, the auxiliary support portion 623 of the first link member 611 is connected to the upper portion of the auxiliary cover C2. Thus, in the auxiliary overlapping state, the auxiliary cover 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 with respect to the first swing axis Ax1. be done. Therefore, in the auxiliary overlapping state of the auxiliary cover C2, the auxiliary cover C2 is arranged on the first side Y1 in the door movement direction with respect to the retracted movable cover C1 arranged below the first swing axis Ax1. is made.

In this embodiment, the first link member 611 is formed in a plate shape extending in two directions from the first swing axis Ax1. To explain, the direction in which the first movable-side extension 611b extends and the direction in which the auxiliary-side extension 611c extend intersect each other. In this example, these extending directions are orthogonal to each other when viewed from the wall orthogonal direction X. As shown in FIG. That is, the first link member 611 is formed in an L shape when viewed in the wall orthogonal direction X. As shown in FIG.

In this embodiment, the second link member 612 includes a second shaft support portion 612a arranged on the second swing axis Ax2, a second support portion 622 provided with the second connection axis CAx2, a second shaft and a second movable side extension portion 612b extending from the support portion 612a (the second swing axis Ax2) to the second support portion 622. The second link member 612 is inserted through the shaft member along the second swing axis Ax2 at the second shaft support portion 612a. Thereby, the second link member 612 is connected to the connecting member 52 so as to be able to swing about the second swing axis Ax2.

A second support portion 622 (support portion 62) that swingably supports the movable cover C1 is formed at a position spaced apart from the second swing axis Ax2 in the second movable side extension portion 612b. The movable cover C1 is connected to the second support portion 622 so as to be able to swing about the second connection axis CAx2. In this example, when the movable cover C1 is in the overlapping state (see FIG. 6), the second connection axis CAx2 is arranged below the second swing axis Ax2. More specifically, the second swing axis Ax2 and the second connection axis CAx2 are arranged vertically side by side. Therefore, the second movable-side extending portion 612b is arranged to extend downward from the second shaft support portion 612a when the movable cover C1 is in the overlapping state. This makes it easy to dispose the movable cover C1 at a position corresponding to the notch 51 disposed below the second swing axis Ax2. In this embodiment, the second link member 612 is formed in a strip shape extending along one direction.

Next, 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 closed will be described with reference to FIGS. 6 to 8. FIG.

As shown in FIG. 6, when the fire door 3 is open, the movable cover C1 overlaps with the notch 51 when viewed in the wall-perpendicular direction X, and the auxiliary cover C2 is positioned in the wall-perpendicular direction X. , it becomes an auxiliary overlap state in which it is arranged so as to overlap with the area of the notch 51 that does not overlap with the movable cover C1. At this time, the movable cover C1 is urged to overlap by its own weight. Here, the movable cover C1 is sufficiently heavier than the auxiliary cover C2. Therefore, regardless of the gravity acting on the auxiliary cover C2, the movable cover C1 is in the overlapping state, whereby the auxiliary cover C2 is in the auxiliary overlapping state. This eliminates the need for an urging mechanism such as a spring.

As shown in FIG. 7, when the fire door 3 shifts to the closing operation, the movable cover C1 is pushed by the fire door 3 from the second side Y2 in the door moving direction to the first side Y1 in the door moving direction. As a result, the first link member 611 connected to the movable cover C1 swings around the first swing axis Ax1, and the second link member 612 similarly connected to the movable cover C1 swings as the second swing shaft. It swings around the heart Ax2. As a result, the movable cover C1 swings upward in the door movement direction first side Y1 and retreats upward from the door movement locus P3. At this time, the arrangement position of the movable cover C1 and the link member 61 (second The shape and size of the first link member 611 and the second link member 612) are set. Therefore, the movable cover C1, which changes state between the overlapping state and the retracted state, does not come into contact with the frame end portion 30a. On the other hand, the auxiliary cover C2 connected to the first link member 611 is arranged so as to overlap the moving locus of the edge of the movable cover C1 on the door moving direction first side Y1 in the wall orthogonal direction X view in the auxiliary overlapping state. ing. As the first link member 611 swings, the auxiliary cover C2 moves ahead of the movable cover C1 on the movement trajectory of the edge of the movable cover C1 on the first side Y1 in the door movement direction. It swings upward from the end region of the door moving direction first side Y1 in the door moving locus P3.

As shown in FIG. 8, when the fire door 3 is closed, the movable cover C1 is in a retracted state in which it is retracted from the door movement path P3, and the auxiliary cover C2 is also in an auxiliary retracted state in which it is retracted from the door movement path P3. In this embodiment, when the fire door 3 is closed, the movable cover C<b>1 and the auxiliary cover C<b>2 are retracted upward from the door movement locus P<b>3 and arranged above the fire door 3 . The fire door 3 abuts against the frame end portion 30a to close the opening 40 in plan view. As a result, when a fire breaks out, it is possible to suppress the spread of fire between floors that are vertically adjacent to each other with the fire doors 3 interposed therebetween.

Here, for example, when the fire door 3 no longer needs to close the opening 40, the fire door 3 performs an opening operation to change 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 operate in the order of FIGS. 8, 7 and 6. FIG.

As described above, the movable cover C1 is no longer pushed by the fire door 3 as the fire door 3 opens, so that the movable cover C1 enters the door movement locus P3 while moving from the retracted state toward the second side Y2 in the door movement direction. It is configured so that it swings and becomes an overlapping state. In this embodiment, the movable cover C1 descends by its own weight as the fire door 3 opens, and shifts from the retracted state to the overlapping state.

As shown in FIG. 8, in the retracted state of the movable cover C1, the first connection axis CAx1, which is the connection portion between the movable cover C1 and the first link member 611, is the first link member 611 pivotal center. A second connection axis CAx2, which is arranged on the first side Y1 in the door movement direction from the first swing axis Ax1 and is a connection portion between the movable cover C1 and the second link member 612, is connected to the second link member 612. is arranged on the first side Y1 in the door movement direction from the second swing axis Ax2 which is the swing center of the door. Therefore, in the retracted state of the movable cover C1 (closed state of the fire door 3), the movable cover C1 suspended and supported by the first link member 611 and the second link member 612 moves downward (in the illustrated example) due to its own weight. clockwise). Therefore, when the fire door 3 performs the opening operation, the movable cover C1 is not supported by the fire door 3 and swings downward by its own weight. As a result, the movable cover C1 is put in an overlapping state. The first link member 611 also supports the auxiliary cover C2 at the auxiliary support portion 623 in addition to the movable cover C1. Accordingly, when the fire door 3 is opened and the movable cover C1 is lowered, the auxiliary cover C2 is also lowered to enter the auxiliary overlapping state.

[Other embodiments]
Next, another embodiment of the article transport facility will be described.

(1) In the above embodiment, the swing support mechanism 6 includes the first link member 611 and the second link member 612 as the link members 61 for swingably supporting the movable cover C1. explained. However, without being limited to such an example, the swing support mechanism 6 may be configured to include only one of the first link member 611 and the second link member 612 . In this case, it is preferable to select suitable locations for supporting the movable cover C1 by the first link member 611 or the second link member 612 so as to support the movable cover C1 in a well-balanced manner.

(2) In the above embodiment, the first link member 611 is formed in a long plate shape (L-shaped when viewed in the direction perpendicular to the wall X) extending along two directions, and the second link member 612 is formed in one direction. An example in which it is formed in a long plate shape extending along the direction has been described. However, without being limited to such an example, the shape of the first link member 611 and the shape of the second link member 612 may be appropriately rectangular, polygonal, circular, elliptical, or the like when viewed in the wall orthogonal direction X. May be changed.

(3) In the above embodiment, the example in which the rocking support mechanism 6 that rockably supports the movable cover C1 with respect to the partition wall 5 is configured as a link mechanism including the link member 61 has been described. However, without being limited to such an example, the swing support mechanism 6 may be configured as a hinge mechanism as shown in FIG. 9, for example. In this case, the swing support mechanism 6 connects the connecting member 52 of the partition wall 5 and the movable cover C1, and supports the plate-like movable cover C1 so as to swing in a direction perpendicular to the plate surface thereof. A hinge portion 63 is preferably provided. Further, in this case, the door movement direction Y is preferably the direction along the wall orthogonal direction X orthogonal to the partition wall 5 . Even with such a configuration, the movable cover C1 is pushed by the fire door 3 as the fire door 3 closes, and thus enters a retracted state in which it retracts from the door movement locus P3. When the fire door 3 is opened, the movable cover C1 is no longer pushed by the fire door 3, so that the movable cover C1 swings from the retracted state to the door movement locus P3 by its own weight, and becomes an overlapping state. .

(4) In the above-described embodiment, an example has been described in which the movable cover C1 is changed between the overlapping state and the retracted state by swinging the movable cover C1 using the swing support mechanism 6 . However, without being limited to such an example, the movable cover C1 may be changed between the overlapping state and the retracted state without using the swing support mechanism 6 . For example, in the example shown in FIG. 10, the movable cover C1 is supported by the connecting member 52 in a state in which it is allowed to move only in the vertical direction, and is provided on the end surface of the second side Y2 in the door moving direction. It has a cover slope C1a that slopes upward toward Y2. In addition, the fire door 3 has a door inclined surface 3a on the end surface of the first side Y1 in the door movement direction, which is inclined upward toward the second side Y2 in the door movement direction. As the fire door 3 closes, the cover inclined surface C1a is pushed from the door moving direction second side Y2 toward the door moving direction first side Y1 by the door inclined surface 3a. An upward force acts, and the cover inclined surface C1a moves upward on the door inclined surface 3a. As a result, the movable cover C1 is retracted upward from the door movement locus P3 to be in a retracted state. Further, the movable cover C1 is no longer pushed by the fire door 3 as the fire door 3 opens, so that the movable cover C1 moves from the retracted state to the door movement locus P3 by its own weight, and becomes an overlapping state.

(5) In the above embodiment, an example in which the article transport facility 100 includes the auxiliary cover C2 in addition to the movable cover C1 has been described. However, without being limited to such an example, the article transport facility 100 may not include the auxiliary cover C2.

(6) In the above embodiment, the target wall 4T formed with the opening 40 through which both the first transport path P1 and the second transport path P2 pass is the floor 4 of the facility, that is, the target wall 4T is horizontal. An example in which they are arranged along a direction has been described. However, without being limited to such an example, the target wall 4T may be a wall arranged along the vertical direction. For example, the target wall 4T may be a vertical wall or the like that divides a plurality of fire prevention areas that are arranged on the same floor in the facility. In this case, the first transport path P1 and the second transport path P2 are set along the horizontal direction. Also, the target wall 4T may be a wall arranged along a direction that is inclined with respect to the horizontal direction and the vertical direction.

(7) In the above embodiment, an example in which the surrounding wall 96 is provided to surround the first conveying path P1 and the second conveying path P2 along the conveying direction has been described. It does not have to be provided.

(8) In the above-described embodiment, the configuration in which the movable cover C1 is biased by its own weight in the overlapping state has been described as an example. However, it is not limited to this. The movable cover C1 may be biased in the overlapping state by the biasing force of an elastic member such as a spring.

(9) It should be noted that the configurations disclosed in the above-described embodiments can be applied in combination with configurations disclosed in other embodiments as long as there is no contradiction. Regarding other configurations, the embodiments disclosed in this specification are merely examples in all respects. Therefore, various modifications can be made as appropriate without departing from the scope of the present disclosure.

[Overview of the above embodiment]
The article transport equipment described above will be described below.

A first conveying path and a second conveying path arranged parallel to each other along a conveying direction in which an article is conveyed, a first conveying device moving along the first conveying path, and along the second conveying path and a second conveying device that moves by
a partition wall separating the first transport path and the second transport path along the transport direction;
a target wall arranged to intersect the conveying direction;
an opening that penetrates the target wall in the transport direction and through which both the first transport path and the second transport path pass;
A state change between a closed state in which the opening is closed by moving parallel to the opening surface of the opening and an open state in which the opening is opened to open both the first conveying path and the second conveying path. a fire door for
A notch portion is formed in the partition wall in a region overlapping a door movement trajectory, which is a movement trajectory of the fire door,
The fire door is arranged on both sides of the partition wall in a state of penetrating the notch in the closed state,
A direction orthogonal to the partition wall is defined as a wall orthogonal direction, and the partition wall includes an overlapping state in which the partition wall overlaps the notch when viewed in the wall orthogonal direction along the wall orthogonal direction, and the door movement trajectory. A movable cover is provided that changes its state to a retracted state that retracts from
The movable cover is biased so as to be in the overlapping state in the open state of the fire door, and moves toward the fire door in accordance with a closing operation for changing the state of the fire door from the open state to the closed state. It is pushed to be in the retracted state.

According to this configuration, since the cutout portion is formed in the region overlapping the door movement locus in the partition wall, the fire door can be arranged across both sides of the partition wall, and when the fire door is closed, A fire door can be arranged so as to overlap both the first transport path and the second transport path to close the opening of the target wall. Therefore, the fire door can be shared by the first transport route and the second transport route, and an increase in cost and installation space due to an increase in the number of installed fire doors can be suppressed. In the closed state of the fire door, the movable cover provided on the partition wall is pushed by the closing fire door to be in a retracted state in which the movable cover is retracted from the door movement trajectory. On the other hand, in the open state in which the fire door opens both the first transport path and the second transport path, the movable cover is in an overlapping state in which it is arranged so as to overlap the notch portion when viewed in the direction perpendicular to the wall. Therefore, the overlapped movable cover can block the area on the side where the first transport path is arranged and the area on the side where the second transport path is arranged across the partition wall. Therefore, according to this configuration, the notch formed in the partition wall allows the fire door to be arranged across both sides of the partition wall, and in the overlapped state, the notch can be seen in the direction orthogonal to the wall. Movable covers arranged so as to overlap make it possible to properly partition both sides of the partition wall.

Here, the direction in which the fire door moves is defined as the door movement direction, the side to which the fire door moves by the closing operation is defined as the first side in the door movement direction, and the fire door changes state from the closed state to the open state. Assuming that the side moved by the opening operation for opening is the second side in the door moving direction,
further comprising a swing support mechanism that swingably supports the movable cover with respect to the partition wall;
The movable cover is pushed from the second side in the door moving direction by the fire door in accordance with the closing operation of the fire door, thereby moving the door while moving from the overlapped state to the first side in the door moving direction. It swings so as to retreat from the trajectory to enter the retracted state, and is no longer pushed from the fire door as the fire door opens, thereby moving from the retracted state to the second side in the door moving direction. It is preferable that the overlapping state is achieved by swinging so as to enter the door movement locus.

According to this configuration, the movable cover is pushed by the closing action of the fire door to swing the movable cover to the retracted state, and the opening action of the fire door prevents the movable cover from being pushed by the fire door. It can be swung in the opposite direction to the overlapping state. Therefore, with a simple structure in which the movable cover is oscillatably supported with respect to the partition wall by the oscillating support mechanism, the movable cover changes state between the overlapping state and the retracted state in accordance with the operation of the fire door. realizable.

In addition, in the configuration including the rocking support mechanism,
The door moving direction is a direction along the target wall,
The rocking support mechanism includes a link member rocking around a rocking axis orthogonal to the partition wall,
The movable cover is pivotably connected to a supporting portion of the link member spaced apart from the pivot axis,
The swing axis of the link member is arranged above the notch,
The movable cover enters the overlapping state while being suspended and supported by the link member, swings from the overlapping state so as to move upward while moving in the first side in the door movement direction, and enters the retracted state. is suitable.

According to this configuration, the movable cover can be biased into the overlapping state by its own weight. Therefore, it is possible to realize a configuration in which the movable cover is biased so as to overlap when the fire door is open without using a biasing mechanism such as a spring.

In addition, in the configuration in which the rocking support mechanism includes a link member,
further comprising an auxiliary cover arranged in parallel with the movable cover along the direction of movement of the door;
The auxiliary cover is
As the state of the movable cover changes, the state changes between an auxiliary overlapping state in which the movable cover overlaps with the notch when viewed in the direction perpendicular to the wall, and an auxiliary retreat state in which the door moves away from the locus of movement of the door. connected to the link member to
In the auxiliary overlapping state, when the movable cover moves between the overlapping state and the retracted state when viewed from the first side in the door moving direction with respect to the movable cover and in the direction orthogonal to the wall. arranged in a region that overlaps with the movement trajectory of the edge of the movable cover on the first side in the door movement direction,
As the movable cover changes from the overlapped state to the retracted state, the movable cover swings from the auxiliary overlapped state to the second side in the door moving direction and moves upward to the auxiliary retracted state. Then, it is suitable.

When the movable cover swings upward while moving in the first side in the door moving direction in order to move from the overlapped state to the retracted state, the movable cover moves toward the first side in the door moving direction. You need room to move. Therefore, when the movable cover is in an overlapping state, it is difficult to dispose the movable cover so as to overlap the entire cutout portion when viewed in the direction orthogonal to the wall. In this case, even if the movable cover is in the overlapped state, a gap that is not covered by the movable cover is generated in the end region of the notch on the first side in the door movement direction when viewed in the wall orthogonal direction. However, according to this configuration, an auxiliary portion is added to a region that is on the first side in the door moving direction with respect to the movable cover and that overlaps with the movement locus of the edge of the movable cover on the first side in the door moving direction when viewed in the direction perpendicular to the wall. A cover can be placed. As a result, the area on the side where the first conveying path is arranged and the area on the side where the second conveying path is arranged can be cut off more appropriately across the partition wall. Further, the auxiliary cover is interlocked with the movable cover, and when the movable cover is in the retracted state, it is in the auxiliary retracted state in which it retracts from the door movement locus. Therefore, even with this configuration including the auxiliary cover, the auxiliary cover does not hinder the movement of the fire door.

Further, the first conveying device and the second conveying device are configured to convey articles in a vertical direction over a plurality of floors,
The target wall is the floor of the facility,
Preferably, the fire door moves along the floor.
