Description

The present invention relates to an article transport facility provided with a transport device for transporting articles and a fire door.

For example, in Japanese Patent No. 6304057 (Patent Document 1), an article transport device (2) for transporting an article (1) over a plurality of floors through an opening (f) formed in a floor portion (F) of each floor. ) Is disclosed. The goods transporting equipment is provided with a fire door (34) that normally opens the opening (f) and closes the opening (f) in the event of a fire. The reference numerals shown in parentheses above are those of Patent Document 1.

Japanese Patent No. 6304057

Here, in the article transport facility provided with the article transport device as described above, from the viewpoint of improving the transport efficiency of the article, for example, by arranging the two article transport devices side by side, the amount that can be transported is increased. Can be considered. In this case, maintenance of the article transporting device may be required, but maintenance of one article transporting device is performed by partitioning the two article transporting devices with a partition wall so that the two article transporting devices can be maintained separately. Sometimes, even when the other article transporting device is in operation, the safety of the maintenance operator can be ensured.

By the way, when the article transporting device is installed across a fire prevention section such as a floor or a wall, the opening provided in the floor or the wall for the article transporting device to pass through can be closed in the event of a fire. It is necessary to install a fire door in. In the case where the two article transporting devices are provided as described above, fire prevention is provided in each of the area where one article transporting device is provided and the area where the other article transporting device is provided across the partition wall. It is conceivable to provide a door. However, if the number of fire doors installed increases, the cost and installation space will increase accordingly. On the other hand, it is also conceivable to use one fire door, provide a notch portion penetrating both of the above areas in a part of the partition wall, and arrange the fire door so as to straddle the two areas.

However, when the fire door is shared in both areas in this way, the notch provided in the partition wall is in the open state when the fire door is open. When the notch is in such a state, there is a possibility that the limbs of the worker or the equipment used for maintenance may jump out to the other area through the notch when maintenance is being performed in one area. Therefore, the article transfer device cannot be operated in the other area.

In view of the above situation, in an article transport facility provided with a partition wall that partitions two article transport devices along a transport path, fire doors are arranged across both sides of the partition wall to appropriately partition both sides of the partition wall. It is hoped that the technology that enables this will be realized.

A first transport path and a second transport path arranged parallel to each other along the transport direction in which articles are transported, a first transport device that moves along the first transport path, and a second transport path. An article transport facility equipped with a second transport device that moves in a parallel manner.
A partition wall that separates the first transport path and the second transport path along the transport direction, and
The target walls arranged so as to intersect in the transport direction,
An opening that penetrates the target wall in the transport direction and passes through both the first transport path and the second transport path.
The state changes between a closed state in which the opening moves parallel to the opening surface to close the opening and an open state in which the opening is opened to open both the first transport path and the second transport path. With a fire door,
A notch is formed in the partition wall in a region overlapping the door movement locus, which is the movement locus of the fire door.
The fire door is arranged on both sides of the partition wall in the closed state so as to penetrate the notch.
The direction orthogonal to the partition wall is defined as the wall orthogonal direction, and the partition wall is arranged so as to overlap the notch portion in the wall orthogonal direction view along the wall orthogonal direction, and the door movement locus. A movable cover is provided that changes the state between the retracted state and the retracted state.
The movable cover is urged so as to be in the overlapping state in the open state of the fire door, and is attached to the fire door as the fire door changes from the open state to the closed state. It is pushed to the retracted state.

According to this configuration, since the notch is formed in the area overlapping the door movement locus on the partition wall, the fire door can be arranged across both sides of the partition wall, and the fire door can be arranged in the closed state. Fire doors 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 path and the second transport path, and it is possible to suppress an increase in cost and installation space due to an increase in the number of fire doors installed. Then, in the closed state of the fire door, the movable cover provided on the partition wall is pushed by the fire door that performs the closing operation, so that the movable cover is retracted from the door movement locus. 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 the movable cover is arranged so as to overlap the notch in the wall orthogonal direction view. Therefore, the overlapping movable covers 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 fire doors can be arranged across both sides of the partition wall by the notch formed in the partition wall, and in the overlapping state, the wall is orthogonal to the notch. Movable covers arranged so as to overlap each other make it possible to appropriately partition both sides of the partition wall.

Further features and advantages of the techniques according to the present disclosure will be further clarified by the following illustration of exemplary and non-limiting embodiments described with reference to the drawings.

Specifically, the target wall 4T is arranged so as to be orthogonal to the transport direction and the partition wall 5 described later. In the present embodiment, the target wall 4T is the floor portion 4 of the equipment. Specifically, the target wall 4T is a floor portion 4 other than the floor portion 4 on the lowest floor of the article transport facility 100. FIG. 1 illustrates a three-story article transport facility 100, and shows an example in which the floor portions 4 on the second and third floors are the target walls 4T. The floor 4 on the first floor is not the target wall 4T.

The article transport facility 100 includes a partition wall 5 that partitions between the first transport path P1 and the second transport path P2 along the transport direction. In the present embodiment, the partition wall 5 is provided inside the surrounding wall 96. In this example, the partition walls 5 are arranged along the vertical direction. The inside of the surrounding wall 96 is divided by a partition wall 5 into a first area A1 in which the first transport device 1 is arranged and a second area A2 in which the second transport device 2 is arranged. The first transport device 1 is configured to transport the article W along the vertical direction in the first area A1. The second transport device 2 is configured to transport the article W along the vertical direction in the second area A2. In the following, the direction orthogonal to the partition wall 5 will be referred to as the wall orthogonal direction X. Further, in the wall orthogonal direction X, the side on which the first transport device 1 is arranged with respect to the partition wall 5 is designated as the first side X1 in the wall orthogonal direction, and the side on which the second transfer device 2 is arranged with respect to the partition wall 5 Is the second side X2 in the wall orthogonal direction. In the present embodiment, the wall orthogonal direction X is a direction along the horizontal direction.

The first transport device 1 includes a first guide rail 11 arranged over a plurality of floors along a transport direction (vertical direction in this example), and a first elevating body 13 that moves up and down along the first guide rail 11. A first transfer unit 14 that is supported by the first elevating body 13 and holds and transfers the article W is provided. In the present embodiment, the first transfer unit 14 includes a first transfer holding unit 141 capable of holding the article W, a mechanism unit for horizontally moving the first transfer holding unit 141, and a first transfer holding unit. A mechanism portion for rotating the portion 141 around an axial center along the vertical direction is provided. As a result, the first transfer portion 14 is placed between the plurality of holding portions 7 arranged horizontally apart from the first guide rail 11 at a plurality of locations around the first guide rail 11. Can be reprinted. For example, the first transfer unit 14 is configured by using a horizontal articulated arm (so-called SCARA; Selective Compliance Assembly Robot Arm). In the illustrated example, a pair of first transfer portions 14 are arranged vertically and supported by the same first elevating body 13.

The second transport device 2 includes a second guide rail 21 arranged over a plurality of floors along a transport direction (vertical direction in this example), and a second elevating body 23 that moves up and down along the second guide rail 21. A second transfer unit 24, which is supported by the second elevating body 23 and holds and transfers the article W, is provided. In the present embodiment, the second transfer section 24 includes a second transfer holding section 241 capable of holding the article W, a mechanism section for moving the second transfer holding section 241 in and out in the horizontal direction, and a second transfer holding section. A mechanism portion for rotating the portion 241 around an axial center along the vertical direction is provided.

Can be reprinted. For example, the second transfer portion 24 is configured by using a horizontal articulated arm. In the illustrated example, a pair of second transfer portions 24 are arranged vertically and supported by the same second elevating body 23. As described above, in the present embodiment, the first transfer device 1 and the second transfer device 2 have the same structure.

The article transport facility 100 includes an opening 40 that penetrates the target wall 4T in the transport direction and allows both the first transport path P1 and the second transport path P2 to pass through. In the example shown in FIG. 1, openings 40 are formed in each of the floor portions 4 on the second and third floors, which are the target walls 4T. The opening 40 is formed so as to penetrate each of the floor portions 4 in the vertical direction. Both the first guide rail 11 and the second guide rail 21 are inserted through the opening 40. The opening 40 is formed to be larger than the total of the arrangement areas of the first transfer device 1 and the second transfer device 2 in a plan view. The first transfer device 1 and the second transfer device 2 come and go between the floors through the opening 40.

The article transport facility 100 moves in parallel with the opening surface of the opening 40 to close the opening 40 and to open both the first transport path P1 and the second transport path P2 by opening the opening 40. It is provided with a fire door 3 that changes state and state. The fire door 3 is configured to move along the floor portion 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 orthogonal to the partition wall 5. In the present embodiment, the door moving direction Y is further orthogonal to the wall orthogonal direction X. In the illustrated example, the fire door 3 is configured to be supported by the door support frame 30 installed on the target wall 4T and to be guided by the door support frame 30 to move along the door moving direction Y. As shown in FIG. 8, the fire door 3 abuts on the frame end 30a of the door support frame 30 arranged so as to face the door moving direction Y with respect to the fire door 3 in the closed state. The fire door 3 closes the opening 40 in a plan view by contacting the frame end portion 30a in the closed state. In the following, in the door moving direction Y, the side that moves by the closing operation for changing the state of the fire door 3 from the open state to the closed state is referred to as the door moving direction first side Y1, and the fire door 3 is changed from the closed state to the open state. The side that moves due to the opening operation for changing the state is defined as the second side Y2 in the door moving direction.

2 to 6 show a case where the fire door 3 is in an open state. When the first transfer device 1 and the second transfer device 2 are in operation, the fire door 3 is opened. Further, 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 the present embodiment, the article transport facility 100 is provided with a first workbench 91 and a second workbench 92 that can be arranged so as to cover a part of the opening 40. The first workbench 91 is configured to cover a part of the opening 40 in the first area A1 in the unfolded state, and the second workbench 92 is configured to cover a part of the opening 40 in the second area A2 in the unfolded state. It is configured to cover a part of. The first workbench 91 and the second workbench 92 can be used as scaffolding 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 in a folded and stored state are shown. Further, in the illustrated example, the first ladder L1 is provided in the first area A1 and the second ladder L2 is provided in the second area A2. The first ladder L1 and the second ladder L2 can also be used at the time of maintenance. The first ladder L1 and the second ladder L2 are detachably provided and can be removed when maintenance is not performed. Further, in the present embodiment, a plurality of emergency stop switches S for stopping the operation of the first transfer device 1 or the second transfer device 2 are provided. The emergency stop switch S is used as needed by a maintenance worker or the like. In the illustrated example, the emergency stop switches S are provided at a plurality of locations inside and outside the surrounding wall 96. As a result, the 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 a case where the fire door 3 is in the closed state. When a fire breaks out, the fire door 3 is closed by a closing operation to close the opening 40 and suppress the spread of fire between adjacent floors. The fire door 3 is configured to be automatically closed when a fire is detected by a fire detection sensor (not shown) provided in the article transport facility 100 or the like. When the fire door 3 is closed, both the first transport device 1 and the second transport device 2 stop at positions that do not interfere with the fire door 3.

Here, the partition wall 5 is formed with a notch 51 in a region overlapping the door movement locus P3, which is the movement locus of the fire door 3. In the present embodiment, as shown in FIG. 4, the partition wall 5 includes a partition plate 50 that separates the first area A1 and the second area A2. The partition plate 50 is provided on each of the plurality of floors. A pair of partition plates 50 provided on each of two adjacent floors are arranged vertically separated from each other. The above-mentioned notch 51 is formed between the pair of partition plates 50 in the vertical direction. The fire door 3 is arranged on both sides of the partition wall 5 in a closed state so as to penetrate the notch 51. As a result, the fire door 3 can be arranged so as to overlap both the first transport path P1 and the second transport path P2 in the closed state of the fire door 3, and the opening 40 of the target wall 4T can be closed. Therefore, the fire door 3 can be shared by the first transport path P1 and the second transport path P2, and it is possible to suppress an increase in cost and installation space due to an increase in the number of fire doors installed. 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 transport path P1 and the second transport path P2.

As shown in FIGS. 5 to 8, the partition wall 5 is arranged so as to overlap the notch 51 in the wall orthogonal direction X along the wall orthogonal direction X, and is retracted from the door movement locus P3. A movable cover C1 that changes its state to the retracted state is provided. In the present 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. 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 C1 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 portion 51 in the wall orthogonal direction X view, and more specifically, the partition plate 50 is provided so as to be adjacent to the notch portion 51 upward. It is provided at the lower end of the. As a result, the movable cover C1 connected to the connecting member 52 is easily overlapped with respect to the cutout portion 51 in the wall orthogonal direction X view.

The movable cover C1 is urged so as to be in an overlapping state 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 with the notch 51 in the wall orthogonal direction X view. Therefore, the movable cover C1 and the partition plate 50 can block the first area A1 and the second area A2 that sandwich the partition wall 5. Therefore, when maintenance is performed in either the first area A1 or the second area A2, even if the area where the maintenance is not performed is set to the operating state, the work during the maintenance work is performed in the operating state area. It is possible to reduce the possibility that a person's limbs or equipment used for maintenance will pop out through the notch 51.

Further, the movable cover C1 is configured to be pushed by the fire door 3 in the retracted state as the fire door 3 is closed (see FIGS. 7 and 8). As a result, even if the movable cover C1 is provided so as to overlap the notch 51 in the wall orthogonal direction X view, when the fire door 3 is closed, the movable cover C1 is pushed away. The fire door 3 can be closed. That is, the movable cover C1 does not interfere with the closing operation of the fire door 3.

As described above, the movable cover C1 is in an overlapping state overlapping the notch 51 in the wall orthogonal direction X view in the open state where the fire door 3 opens the opening 40, and the fire door 3 is in the closed state where the fire door 3 closes the opening 40. It is in a retracted state of retracting from the door movement locus P3 of 3. Therefore, according to the article transport facility 100, the fire doors 3 are 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. The movable cover C1 is arranged so as to overlap the notch 51 in the wall orthogonal direction X view in the overlapping state, so that both sides of the partition wall 5 are covered even when the fire door 3 is in the open state. It is possible to partition appropriately.

In the present embodiment, the article transport facility 100 includes, in addition to the movable cover C1, an auxiliary cover C2 which is arranged so as to overlap the notch 51 in the wall orthogonal direction X view. In the present 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. The auxiliary cover C2 is configured to overlap the movable cover C1 in the notch 51 in a region that does not overlap with the movable cover C1 in the wall orthogonal direction X view. Details will be described later.

In the present embodiment, the article transport facility 100 includes a swing support mechanism 6 that swingably supports the movable cover C1 with respect to the partition wall 5. In this example, the swing support mechanism 6 swingably supports the auxiliary cover C2 with respect to the partition wall 5 in addition to the movable cover C1. The swing support mechanism 6 is configured to swing the movable cover C1 and the auxiliary cover C2 in the directions along the respective plate surfaces. That is, the movable cover C1 and the auxiliary cover C2 that are oscillated by the oscillating support mechanism 6 are in a state in which each plate surface faces the wall orthogonal direction X around the oscillating axis Ax along the wall orthogonal direction X. It is configured to swing with.

In the present embodiment, the swing support mechanism 6 includes a link member 61 that swings around the swing axis Ax orthogonal 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 the swing axis Ax is the first swing axis Ax1 and the second swing axis Ax. It has a drive 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 in the partition wall 5 so as to swing around the first swing axis Ax1. The second link member 612 is supported by the connecting member 52 in the partition wall 5 so as to swing around the second swing axis Ax2. Here, the second swing axis Ax2 is arranged on the second side Y2 in the door moving direction with respect to the first swing axis Ax1. Further, the second swing axis Ax2 is arranged above the first swing axis Ax1.

In the present embodiment, the movable cover C1 is swingably connected to the support portion 62 of the link member 61 separated from the swing axis Ax. In this example, the first link member 611 includes a first support portion 621 as a support portion 62 at a position separated from the first swing axis Ax1. Further, the first link member 611 also includes an auxiliary support portion 623 that supports the auxiliary cover C2, and this point will be described later. Then, the first connecting portion C11 provided on the movable cover C1 is swingably connected to the first support portion 621 around the first connecting axis CAx1. Further, in this example, the second link member 612 is provided with a second support portion 622 as a support portion 62 at a position separated from the second swing axis Ax2. Then, the second connecting portion C12 provided on the movable cover C1 is swingably connected to the second supporting portion 622 around the second connecting axis CAx2. In the present embodiment, the second connecting shaft center CAx2 is arranged on the second side Y2 in the door moving direction with respect to the first connecting shaft center CAx1. Further, the second connecting axis CAx2 is arranged above the first connecting axis CAx1. The distance from the first swinging axis Ax1 to the first connecting axis CAx1 and the distance from the second swinging axis Ax2 to the second connecting axis CAx2 are set to be the same. In this example, the second connecting portion C12 on which the second connecting axis CAx2 is arranged is arranged on the second side Y2 in the door moving direction with respect to the first connecting portion C11 on which the first connecting axis CAx1 is arranged. .. More specifically, the first connecting portion C11 is set near the end portion 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 the configuration in which the movable cover C1 is supported by the swing support mechanism 6 in this way, the movable cover C1 is pushed by the fire door 3 from the second side Y2 in the door moving direction as the fire door 3 closes. While moving from the overlapping state to the first side Y1 in the door moving direction, it swings so as to retract from the door moving locus P3 and enters the retracted state (see FIG. 8). Then, the movable cover C1 is not pushed from the fire door 3 as the fire door 3 is opened, so that the movable cover C1 is shaken so as to enter the door movement locus P3 while moving from the retracted state to the second side Y2 in the door moving direction. It moves and becomes an overlapping state (see FIG. 6).

In the present 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. Then, the movable cover C1 is in an overlapping state in a state of being suspended and supported by the link member 61 (first link member 611 and the second link member 612), and while moving from the overlapping state to the first side Y1 in the door moving direction. It is configured to swing upward so as to move upward and to be in a retracted state. As a result, the movable cover C1 can be urged to the overlapping state by its own weight. Therefore, for example, without using an urging mechanism such as a spring, it is possible to realize a configuration in which the movable cover C1 is urged so as to overlap in the open state of the fire door 3.

Here, the auxiliary cover C2 will be described. In the present embodiment, the auxiliary cover C2 is arranged side by side with the movable cover C1 along the door moving direction Y. Specifically, as shown in FIG. 6, when the movable covers C1 are in an overlapping state, the auxiliary covers C2 are arranged side by side with respect to the movable cover C1 on the first side Y1 in the door moving direction.

In the present embodiment, the auxiliary cover C2 is arranged so as to overlap the notch 51 in the wall orthogonal direction X view as the state of the movable cover C1 changes (see FIG. 6), and the fire door. It is connected to the link member 61 so as to change the state to the auxiliary retracted state (see FIG. 8) of retracting from the door moving locus P3, which is the moving locus of 3. In this example, the auxiliary cover C2 is provided on the partition wall 5 by being connected to the connecting member 52 together with the movable cover C1 via the first link member 611. Here, the auxiliary cover C2 is swingably connected to the auxiliary support portion 623 provided at a position separated from the first swing axis Ax1 in the first link member 611. The auxiliary cover C2 is swingably connected to the auxiliary support portion 623 around 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 retracting state when the movable cover C1 is in the retracted state (see FIG. 8).

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

As shown in FIGS. 6 to 8, the auxiliary cover C2 moves upward from the auxiliary overlapping state to the second side Y2 in the door moving direction as the movable cover C1 changes from the overlapping state to the retracted state. It swings to move and becomes an auxiliary evacuation state. In the illustrated example, the auxiliary cover C2 swings upward from the first swing axis Ax1 of the first link member 611 and toward the second side Y2 in the door moving direction, so that the auxiliary cover C2 changes from the auxiliary overlapping state to the auxiliary retracted state. It is configured to be. In the present embodiment, the auxiliary cover C2 is located on the first side Y1 in the door moving direction most in the auxiliary overlapping state (see FIG. 6), and the door is changed from there to the auxiliary retracted state (see FIG. 8). It is configured so as not to be displaced on the first side Y1 in the moving direction. As a result, the auxiliary cover C2 can be prevented from contacting the frame end portion 30a while the state is changing. Therefore, the auxiliary cover C2 in the auxiliary overlapping state can be arranged so as to be close to or in contact with the door moving direction Y with respect to the frame end portion 30a. 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 made as small as possible in the X view in the wall orthogonal direction X, and the first area A1 is formed by the partition wall 5, the movable cover C1 and the auxiliary cover C2. And the second area A2 can be appropriately blocked.

The auxiliary cover C2 that shifts from the auxiliary overlapping state to the auxiliary retracting state follows the movement locus of the edge of the first side Y1 in the door moving direction of the movable cover C1 prior to the movable cover C1 that shifts from the overlapping state to the retracted state. Moving. In other words, the edge of the door moving direction first side Y1 in the movable cover C1 that shifts from the overlapping state to the retracted state moves so as to follow the auxiliary cover C2 that shifts from the auxiliary overlapping state to the auxiliary retracting 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 is in the door moving direction with respect to the frame end portion 30a in the door support frame 30. It comes into contact with the second side Y2 and is closed.

Next, the support structure of 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 includes a first link member 611 and a 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 at the first swinging shaft center Ax1, a first support portion 621 provided with the first connecting shaft center CAx1, and a first shaft. A first movable side extending portion 611b extending from a branch portion 611a (first swinging shaft center Ax1) to a first support portion 621, an auxiliary support portion 623 provided with a third connecting shaft center CAx3, and a first shaft. It is provided with an auxiliary side extending portion 611c extending from the branch portion 611a to the auxiliary supporting portion 623. The first link member 611 is inserted into the shaft member along the first swing shaft center Ax1 at the first shaft support portion 611a. As a result, the first link member 611 is swingably connected to the connecting member 52 around 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 of the first movable side extending portion 611b at a position separated from the first swing axis Ax1. The movable cover C1 is swingably connected to the first support portion 621 around the first connection axis CAx1. In this example, when the movable cover C1 is in an overlapping state (see FIG. 6), the first connecting shaft center CAx1 is arranged below the first swinging shaft center 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. Therefore, the first movable side extending portion 611b is arranged so as to extend downward from the first shaft support portion 611a when the movable cover C1 is in an overlapping state. This makes it easy to arrange the movable cover C1 at a position corresponding to the notch 51 arranged below the first swing axis Ax1.

An auxiliary support portion 623 that swingably supports the auxiliary cover C2 is formed at a position of the auxiliary side extending portion 611c at a position separated from the first swing axis Ax1. The auxiliary cover C2 is swingably connected to the auxiliary support portion 623 around 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 moving direction with respect to the first swinging axis Ax1. More specifically, the third connecting shaft center CAx3 and the first swinging shaft center Ax1 are arranged so as to line up in the door moving direction Y. Therefore, the auxiliary side extending portion 611c extends from the first shaft branch portion 611a toward the first side Y1 in the door moving direction when the movable cover C1 is in the overlapping state and the auxiliary cover C2 is in the auxiliary overlapping state. Arranged like this. This makes it easier to arrange the auxiliary cover C2 in the region of the first side Y1 in the door moving direction than the movable cover C1 in the overlapping state. In this example, the auxiliary support portion 623 of the first link member 611 is connected to the upper part of the auxiliary cover C2. As a result, 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 swinging axis Ax1 in the auxiliary overlapping state. Will 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 moving direction with respect to the retractable movable cover C1 arranged below the first swing axis Ax1. Is done.

In the present embodiment, the first link member 611 is formed in a plate shape extending along two directions from the first swing axis Ax1. To add an explanation, the direction in which the first movable side extending portion 611b extends and the direction in which the auxiliary side extending portion 611c extends intersect with each other. In this example, each of these extending directions is orthogonal to each other in the wall orthogonal direction X-view. That is, the first link member 611 is formed in an L shape in the wall orthogonal direction X view.

In the present embodiment, the second link member 612 includes a second shaft support portion 612a arranged on the second swinging shaft center Ax2, a second support portion 622 provided with the second connecting shaft center CAx2, and a second shaft. A second movable side extending portion 612b extending from the branch portion 612a (second swinging axis Ax2) to the second supporting portion 622 is provided. The second link member 612 is inserted into the shaft member along the second swing axis Ax2 at the second shaft support portion 612a. As a result, the second link member 612 is swingably connected to the connecting member 52 around 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 of the second movable side extending portion 612b at a position separated from the second swing axis Ax2. The movable cover C1 is swingably connected to the second support portion 622 around the second connection axis CAx2. In this example, when the movable cover C1 is in an overlapping state (see FIG. 6), the second connecting shaft center CAx2 is arranged below the second swinging shaft center Ax2. More specifically, the second swing axis Ax2 and the second connecting axis CAx2 are arranged so as to be arranged in the vertical direction. Therefore, the second movable side extending portion 612b is arranged so as to extend downward from the second shaft support portion 612a when the movable cover C1 is in an overlapping state. This makes it easy to arrange the movable cover C1 at a position corresponding to the notch 51 arranged below the second swing axis Ax2. In the present embodiment, the second link member 612 is formed in the shape of a strip extending along one direction.

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

As shown in FIG. 6, when the fire door 3 is open, the movable cover C1 is arranged so as to overlap the notch 51 in the wall orthogonal direction X view, and the auxiliary cover C2 is in the wall orthogonal direction X view. In the notch 51, the movable cover C1 and the movable cover C1 are arranged so as to overlap with the non-overlapping area. At this time, the movable cover C1 is urged to overlap due to 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, and thereby the auxiliary cover C2 is in the auxiliary overlapping state. This makes it possible to eliminate 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 door moving direction second side Y2 to the door moving direction first side Y1. 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 also connected to the movable cover C1 swings around the second swing shaft. It swings around the center Ax2. As a result, the movable cover C1 swings upward on the first side Y1 in the door moving direction and retracts upward from the door moving locus P3. At this time, the arrangement position of the movable cover C1 and the link member 61 (the first The shape and size of the 1-link member 611 and the 2nd link member 612) are set. Therefore, the movable cover C1 whose state changes 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 door moving direction 1st side Y1 of the movable cover C1 in the wall orthogonal direction X view in the auxiliary overlapping state. ing. Then, the auxiliary cover C2 moves on the movement locus of the edge of the first side Y1 in the door moving direction of the movable cover C1 in advance of the movable cover C1 as the first link member 611 swings. It swings so as to retract upward from the end region of the first side Y1 in the door moving direction P3 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 retracted from the door movement locus P3, and the auxiliary cover C2 is also in an auxiliary retracted state retracted from the door movement locus P3. In the present embodiment, in the closed state of the fire door 3, the movable cover C1 and the auxiliary cover C2 retract upward from the door movement locus P3 and are arranged above the fire door 3. Then, the fire door 3 comes into contact with the frame end portion 30a and closes the opening 40 in a plan view. As a result, in the event of a fire, it is possible to suppress the spread of fire between the floors adjacent to the top and bottom of the fire door 3.

Here, for example, when it is no longer necessary to close the opening 40 with 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 operate in the order of FIGS. 8, 7, and 6.

As described above, the movable cover C1 is not pushed from the fire door 3 as the fire door 3 is opened, so that the movable cover C1 enters the door movement locus P3 while moving from the retracted state to the second side Y2 in the door movement direction. It is configured to swing so as to be in an overlapping state. In the present embodiment, the movable cover C1 is lowered by its own weight as the fire door 3 is opened, and the movable cover C1 changes from the retracted state to the overlapping state.

As shown in FIG. 8, in the retracted state of the movable cover C1, the first connecting axis CAx1, which is the connecting portion between the movable cover C1 and the first link member 611, becomes the swing center of the first link member 611. The second connecting shaft CAx2, which is arranged on the first side Y1 in the door moving direction with respect to the swinging shaft Ax1 and is also a connecting portion between the movable cover C1 and the second link member 612, is the second link member 612. It is arranged on the first side Y1 in the door moving direction with respect to the second swinging axis Ax2, which is the swinging 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 is lowered by its own weight (example in the figure). It is urged to swing clockwise). Therefore, when the fire door 3 opens, the movable cover C1 swings so as to be lowered by its own weight without being supported by the fire door 3. As a result, the movable cover C1 is in an overlapping state. Further, the first link member 611 supports the auxiliary cover C2 in the auxiliary support portion 623 in addition to the movable cover C1. Therefore, when the movable cover C1 is lowered due to the opening operation of the fire door 3, the auxiliary cover C2 is also lowered to be in the auxiliary overlapping state.

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

(1) In the above embodiment, the swing support mechanism 6 includes a first link member 611 and a second link member 612 as link members 61 for swingably supporting the movable cover C1. Was explained. However, the swing support mechanism 6 may be configured to include only one of the first link member 611 and the second link member 612 without being limited to such an example. In this case, it is preferable that the position where the movable cover C1 is supported by the first link member 611 or the second link member 612 is appropriately selected 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 shape in the wall orthogonal direction X view) extending along two directions, and the second link member 612 is one. An example in which a long plate extending along the direction is formed 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 formed such as a rectangular shape, a polygonal shape, a circular shape, and an elliptical shape in the wall orthogonal direction X view. May be changed.

(3) In the above embodiment, an example has been described in which the swing support mechanism 6 that swingably supports the movable cover C1 with respect to the partition wall 5 is configured as a link mechanism provided with a link member 61. However, without being limited to such an example, the swing support mechanism 6 may be configured as a hinge mechanism, for example, as shown in FIG. In this case, the swing support mechanism 6 connects the connecting member 52 on the partition wall 5 and the movable cover C1, and supports the plate-shaped movable cover C1 so as to be swingable in a direction orthogonal to the plate surface. It is preferable that the hinge portion 63 is provided. Further, the door moving direction Y in this case is preferably a direction along the wall orthogonal direction X orthogonal to the partition wall 5. Even in such a configuration, the movable cover C1 is pushed by the fire door 3 as the fire door 3 is closed, so that the movable cover C1 is retracted from the door movement locus P3. Then, the movable cover C1 is not pushed from the fire door 3 as the fire door 3 is opened, and due to its own weight, the movable cover C1 swings so as to enter the door movement locus P3 from the retracted state and becomes an overlapping state. ..

(4) In the above embodiment, an example in which the movable cover C1 is swung by the swing support mechanism 6 to change the state of the movable cover C1 between the overlapping state and the retracted state has been described. However, the present invention is not limited to such an example, and 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 where it is allowed to move only in the vertical direction, and is attached to the end surface of the second side Y2 in the door moving direction on the second side in the door moving direction. It has a cover inclined surface C1a that is inclined upward toward Y2. Further, the fire door 3 has a door inclined surface 3a that inclines upward toward the second side Y2 in the door moving direction on the end surface of the first side Y1 in the door moving direction. Then, as the fire door 3 is closed, the cover inclined surface C1a is pushed by the door inclined surface 3a from the second side Y2 in the door moving direction toward the first side Y1 in the door moving direction, so that the cover inclined surface C1a is reached. An upward force acts on the cover inclined surface C1a to move upward on the door inclined surface 3a. As a result, the movable cover C1 retracts upward from the door movement locus P3 and is in the retracted state. Further, the movable cover C1 is not pushed from the fire door 3 as the fire door 3 is opened, so that the movable cover C1 moves from the retracted state to the door movement locus P3 due to 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, the article transporting equipment 100 does not have to be provided with the auxiliary cover C2 without being limited to such an example.

(6) In the above embodiment, the target wall 4T in which the opening 40 through which both the first transport path P1 and the second transport path P2 pass is formed is the floor portion 4 of the equipment, that is, the target wall 4T is horizontal. An example in which they are arranged along the 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 for partitioning a plurality of fire protection areas set to be lined up 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. Further, the target wall 4T may be a wall arranged along a direction inclined with respect to the horizontal direction and the vertical direction.

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

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

(9) The configuration disclosed in the above-described embodiment can be applied in combination with the configuration disclosed in other embodiments as long as there is no contradiction. With respect to other configurations, the embodiments disclosed herein are merely exemplary in all respects. Therefore, various modifications can be made as appropriate without departing from the gist of the present disclosure.

[Outline of the above embodiment]
Hereinafter, the article transport equipment described above will be described.

A first transport path and a second transport path arranged parallel to each other along the transport direction in which articles are transported, a first transport device that moves along the first transport path, and a second transport path. An article transport facility equipped with a second transport device that moves in a parallel manner.
A partition wall that separates the first transport path and the second transport path along the transport direction, and
The target walls arranged so as to intersect in the transport direction,
An opening that penetrates the target wall in the transport direction and passes through both the first transport path and the second transport path.
The state changes between a closed state in which the opening moves parallel to the opening surface to close the opening and an open state in which the opening is opened to open both the first transport path and the second transport path. With a fire door,
A notch is formed in the partition wall in a region overlapping the door movement locus, which is the movement locus of the fire door.
The fire door is arranged on both sides of the partition wall in the closed state so as to penetrate the notch.
The direction orthogonal to the partition wall is defined as the wall orthogonal direction, and the partition wall is arranged so as to overlap the notch portion in the wall orthogonal direction view along the wall orthogonal direction, and the door movement locus. A movable cover is provided that changes the state between the retracted state and the retracted state.
The movable cover is urged so as to be in the overlapping state in the open state of the fire door, and is attached to the fire door as the fire door changes from the open state to the closed state. It is pushed to the retracted state.

According to this configuration, since the notch is formed in the area overlapping the door movement locus on the partition wall, the fire door can be arranged across both sides of the partition wall, and the fire door can be arranged in the closed state. Fire doors 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 path and the second transport path, and it is possible to suppress an increase in cost and installation space due to an increase in the number of fire doors installed. Then, in the closed state of the fire door, the movable cover provided on the partition wall is pushed by the fire door that performs the closing operation, so that the movable cover is retracted from the door movement locus. 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 the movable cover is arranged so as to overlap the notch in the wall orthogonal direction view. Therefore, the overlapping movable covers 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 fire doors can be arranged across both sides of the partition wall by the notch formed in the partition wall, and in the overlapping state, the wall is orthogonal to the notch. Movable covers arranged so as to overlap each other make it possible to appropriately partition both sides of the partition wall.

Here, the direction in which the fire door moves is set as the door moving direction, the side on which the fire door moves by the closing operation is set as the first side in the door moving direction, and the state of the fire door changes from the closed state to the open state. The side that moves by the opening operation is set as the second side in the door movement direction.
A swing support mechanism that swingably supports the movable cover with respect to the partition wall is further provided.
The movable cover is pushed by the fire door from the second side in the door moving direction in accordance with the closing operation of the fire door, so that the movable cover moves from the overlapping state to the first side in the door moving direction. It swings so as to retract from the locus to enter the retracted state, and is not pushed from the fire door as the fire door opens, so that the door moves from the retracted state to the second side in the door moving direction. It is preferable that the door swings so as to enter the door movement locus to enter the overlapping state.

According to this configuration, the movable cover is swung to retract by pushing the movable cover by the closing operation of the fire door, and the movable cover is not pushed by the fire door by the opening operation of the fire door. It can be swung in the opposite direction to create an overlapping state. Therefore, with a simple structure in which the movable cover is swingably supported against the partition wall by the swing support mechanism, the movable cover that changes state between the overlapping state and the retracted state according to the operation of the fire door can be provided. realizable.

In addition, in a configuration provided with a swing support mechanism,
The door moving direction is a direction along the target wall, and is
The swing support mechanism includes a link member that swings around a swing axis perpendicular to the partition wall.
The movable cover is swingably connected to a support portion of the link member that is separated from the swing axis.
The swing axis of the link member is arranged above the notch.
The movable cover is in the overlapping state in a state of being suspended and supported by the link member, and swings so as to move upward while moving from the overlapping state to the first side in the door moving direction to the retracted state. It is preferable.

According to this configuration, the movable cover can be urged to overlap by its own weight. Therefore, for example, without using an urging mechanism such as a spring, it is possible to realize a configuration in which the movable covers are urged so as to be in an overlapping state when the fire door is open.

Further, in a configuration in which the swing support mechanism is provided with a link member,
Further provided with an auxiliary cover arranged side by side with the movable cover along the door moving direction.
The auxiliary cover is
As the state of the movable cover changes, the state changes into an auxiliary overlapping state in which the movable cover is arranged so as to overlap the notch in the wall orthogonal direction view, and an auxiliary retracting state in which the movable cover retracts from the door movement locus. Connected to the link member
In the auxiliary overlapping state, the movable cover is on the first side in the door moving direction with respect to the movable cover, and the movable cover moves between the overlapping state and the retracted state in the wall orthogonal direction view. The movable cover is arranged in an area overlapping the movement locus of the edge on the first side in the door movement direction.
As the movable cover changes from the overlapping state to the retracted state, the movable cover swings so as to move upward while moving from the auxiliary overlapping state to the second side in the door moving direction, and the auxiliary retracted state. Is suitable.

When the movable cover is configured to swing upward while moving to the first side in the door moving direction in order to move from the overlapping state to the retracted state, the movable cover moves to the first side in the door moving direction. You need room to move. Therefore, when the movable covers are in the overlapping state, it is difficult to arrange the movable covers so as to overlap the entire notch portion in the wall orthogonal direction view. In that case, even if the movable covers are overlapped, a gap that is not covered by the movable cover is generated in the end region of the notch portion on the first side in the door moving direction in the wall orthogonal direction view. However, according to this configuration, the region that is on the first side of the door moving direction with respect to the movable cover and overlaps with the movement locus of the edge of the movable cover on the first side of the door moving direction in the direction orthogonal to the wall is assisted. The cover can be placed. As a result, it is possible to more appropriately 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. Further, the auxiliary cover is interlocked with the movable cover, and when the movable cover is in the retracted state, the auxiliary cover is in the auxiliary retracted state in which the movable cover is retracted from the door movement locus. Therefore, even with this configuration provided with the auxiliary cover, the auxiliary cover does not hinder the movement of the fire door.

Further, the first transport device and the second transport device are configured to transport articles in the vertical direction over a plurality of floors.
The target wall is the floor of the equipment.
It is preferable that the fire door moves along the floor portion.

The article transporting equipment is suitable for such equipment provided with a transporting process of transporting articles over a plurality of floors through the floor of each floor.

Further, it is preferable that a surrounding wall is provided so as to surround the first transport path and the second transport path along the transport direction.

According to this configuration, the space in which the first transport path and the second transport path are arranged and the outside can be blocked by the surrounding wall. Therefore, during the operation of the first transport device or the second transport device, it is possible to prevent an operator or the like from inadvertently entering the space in which the first transport path and the second transport path are arranged.

The technique according to the present disclosure can be used for an article transport facility provided with a transport device for transporting articles and a fire door.
