Japanese Unexamined Patent Publication No. 2012-80866

When people and goods enter and leave the building, the entrance to the building is open to the outside environment. Then, when the entrance of the building is open, insects near the entrance may invade the building from the entrance.

Therefore, an object of the present invention is to provide a method for entering a building and an entrance structure of the building, which can prevent insects from invading the building when entering and exiting the building.

The method of entering a building according to an embodiment of the present invention is a method of entering a building when it is detected that a moving body approaching the building entrance provided in the building is located at a first reference position separated by a first distance from the building entrance. A first step of starting spraying toward a moving body from a spraying portion provided at a distance from the building entrance by a second distance shorter than the first distance from the entrance, and a moving body further approaching the building entrance after the first step. However, until it is detected that it is located at the second reference position separated by the second distance, the spraying part continues to spray toward the moving body in the second step, and after the second step, further to the building entrance. When it is detected that the approaching moving body is located at the third reference position separated from the building entrance by a third distance shorter than the second distance, the spraying unit stops spraying, and after the third step and the third step. It has a fourth step of opening the building entrance with the spraying unit stopped spraying.

When the moving body approaching the building entrance is located at the first reference position, the spraying unit starts spraying toward the moving body. This spraying continues until the moving body is in the second reference position. According to this spraying, the mist-like liquid adheres to the blades of the insects perched on the moving body, so that the insects can be removed from the moving body. In addition, since it becomes difficult for insects having liquid attached to the blades to fly, it is possible to prevent insects from flying and invading the building after the building entrance is opened (third step). Therefore, it is possible to prevent insects from invading the building when entering and exiting the building.

In one form, in the first step, the spraying part further starts spraying toward the building entrance, and in the second step, the spraying part continues to spray toward the moving body, and the spraying part sprays toward the building entrance. You may continue. Insects can not only perch on mobiles, but also at the entrance to buildings. According to this process, the insects perched at the entrance of the building are sprayed. Then, it becomes possible to remove insects from the building entrance and prevent insects from flying from the building entrance. Therefore, it is possible to further prevent insects from invading the building when entering and exiting the building.

In one form, the moving body is a vehicle equipped with a container having a vehicle door at the rear end, and in the first step, when it is detected that the rear end of the container is at the first reference position, the spraying unit performs the vehicle door. It may further have a fifth step of spraying towards and after the third step of opening the vehicle door. By the first step and the second step, it becomes possible to remove the insects stuck on the vehicle door and prevent the insects from flying out from the vehicle door. Then, in this state, since the vehicle door is opened, it is possible to prevent insects from invading the container.

In one form, the method of entering the building is the sixth step of connecting the moving body to the building entrance after the fourth and fifth steps, and after the sixth step, the moving body is shorter than the second distance from the building entrance. When it is detected that it is located at the third reference position separated by a third distance, the spraying part sprays toward the upper surface of the container so as to form an area that prevents insects from entering the upper surface of the container. It may further have 7 steps. According to this step, while the goods are being carried from the container into the building, the area that prevents the insects from invading prevents the insects from approaching the building entrance. Therefore, it is possible to further prevent insects from invading the building when entering and exiting the building.

In one form, the method of entering the building is that after the seventh step, the moving body is moved in a direction away from the building entrance, and after the eighth step, the moving body is located at the second reference position. It may further have a ninth step in which the spraying unit stops spraying when detected, and a tenth step in which the vehicle door of the container is closed after the ninth step. According to this step, the invasion of insects into the container to be closed can be suppressed.

Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same elements are designated by the same reference numerals, and duplicate description will be omitted.

[First Embodiment]
First, the entrance structure will be described. As shown in FIG. 1, an example of the entrance structure is the so-called truck berth 1. The truck berth 1 is a place where the truck 100 is stopped to load and unload luggage. The truck berth 1 is provided in the building 101. The building 101 may include, for example, a food factory, a pharmaceutical factory, a museum, and the like.

The truck berth 1 has a carry-in entrance 2 (building entrance), a roof structure 3 (roof portion), and an insect repellent facility 4.

Luggage is loaded and unloaded on the truck 100 through the carry-in entrance 2. The carry-in entrance 2 may be provided at one place in one building 101, or may be provided at a plurality of places as shown in FIG. 1 in a large-scale factory. The carry-in entrance 2 is opened when the cargo is loaded and unloaded, and closed when the cargo is not loaded and unloaded. The carry-in entrance 2 has a building opening 6 (opening) and a shutter 7 (closed portion) (see FIG. 2). The shutter 7 has a state in which the building opening 6 is closed and a state in which the building opening 6 is opened by being rolled up. In other words, the shutter 7 can close the building opening 6. That is, the carry-in inlet 2 can be switched between the closed state (first state) and the open state (second state). The closed portion is not limited to the shutter 7, and various configurations may be adopted as long as the carry-in entrance 2 can be switched between the closed state and the open state. For example, an overdoor or a general door may be adopted as the closing portion.

As shown in FIG. 2, the roof structure 3 covers the upper part of the truck 100 when loading and unloading, and protects the workers engaged in loading and unloading and the truck 100 from wind and rain. The roof structure 3 is provided so as to cover at least the upper part of the carry-in entrance 2, and extends in the horizontal direction (X direction) protruding from the carry-in entrance 2.

The roof structure 3 has a beam steel frame 8, a suspended steel frame 9, and a folded roof 11. The beam steel frame 8 is a foundation member such as H steel that supports the loads of the suspended steel frame 9 and the folded roof 11. One end of the beam steel frame 8 is connected to the structure of the building 101, and the other end extends in a direction (X direction) away from the building 101. That is, the beam steel frame 8 has a cantilever structure. The beam steel frames 8 are arranged apart from each other in a direction (Y direction) orthogonal to the extending direction thereof (see FIG. 1). The roof structure 3 illustrated in the present embodiment has five beam steel frames 8, but the number of beam steel frames 8 is not limited to this.

The suspended steel frame 9 is arranged so that its longitudinal direction is along the Y direction, and is connected to the beam steel frame 8 at a position intersecting the beam steel frame 8. The roof structure 3 illustrated in this embodiment has two suspended steel frames 9, but the number of suspended steel frames 9 is not limited to this.

The folded roof 11 is connected to, for example, a suspended steel frame 9 made of H-steel. That is, the folded roof 11 is arranged under the frame structure 13 (beam steel frame 8 and suspended steel frame 9) constituting the roof structure 3. In the skeleton structure 13, for example, on the flange of the suspended steel frame 9, birds may nest. However, in the roof structure 3 shown in FIGS. 1 and 2, the frame structure 13 is not covered by the folded roof 11, so that the frame structure 13 is exposed to wind and rain. Then, it is possible to prevent birds from forming nests on the suspended steel frame 9.

The roof structure 3 has a first folded roof 11A and a second folded roof 11B. The first folded roof 11A on the building 101 side and the second folded roof 11B on the outside are not continuous with each other. That is, there is a gap between the first folded roof 11A and the second folded roof 11B. Therefore, since rainwater or the like can enter through this gap, a rain gutter 12 (gutter) is arranged below the gap.

The insect repellent equipment 4 suppresses the invasion of insects into the insect repellent area R1. The insect repellent area R1 suppresses insects from invading the interior of the building 101 from the carry-in entrance 2 when the carry-in entrance 2 is in the open state. The insect repellent area R1 is set so as to surround a plurality of carry-in entrances 2.

The insect repellent equipment 4 includes a first sensor 14, a second sensor 16, a third sensor 17, a control device 18 (control unit), and a spray device 19 (spray unit).

The first sensor 14, the second sensor 16, and the third sensor 17 determine whether or not an object exists below the first sensor 14. In other words, the first sensor 14, the second sensor 16, and the third sensor 17 determine the presence or absence of an object (track 100) existing below each of them. For example, the first sensor 14 emits ultrasonic waves vertically downward. The time from when the ultrasonic wave is emitted to when the reflected wave is detected differs between the case where the reflection is performed on the floor surface 110 and the case where the reflection is performed on the container 102 of the truck 100. Therefore, it is determined whether or not an object exists below the sensor based on the time from when the ultrasonic wave is emitted until the reflected wave is detected. The first sensor 14, the second sensor 16, and the third sensor 17 are not particularly limited as long as they can determine whether or not an object exists.

The first sensor 14, the second sensor 16, and the third sensor 17 are connected to the control device 18 arranged in the building 101. Therefore, the outputs of the first sensor 14, the second sensor 16, and the third sensor 17 are transmitted to the control device 18.

The first sensor 14 is attached to the back surface side of the second folded roof 11B. The first sensor 14 is arranged at the position farthest from the outer wall 101a (wall portion) of the building 101 (first reference position). As an example, the distance from the outer wall 101a to the first sensor 14 is the first distance L1.

The second sensor 16 is attached to the lower surface of the gutter 12. That is, it can be said that the second sensor 16 is arranged in the gap of the folded roof 11. Further, it can be said that the second sensor 16 is arranged near the leading edge (second reference position) of the first folded roof 11A on the building 101 side. As an example, the distance from the outer wall 101a to the second sensor 16 is the second distance L2. The second distance L2 is shorter than the first distance L1. For example, when opening the container door 103 (vehicle door) of the truck 100, which will be described later, a predetermined distance is required between the rear end 102a of the container 102 and the carry-in entrance 2. Based on this configuration, the second distance L2 may be a distance from the outer wall 101a required to open the container door 103.

The third sensor 17 is attached to the back surface of the first folded roof 11A above the carry-in entrance 2. That is, the third sensor 17 is arranged at a position closest to the outer wall 101a (third reference position) as compared with the first sensor 14 and the second sensor 16. As an example, the distance from the outer wall 101a to the third sensor 17 is the third distance L3. The third distance L3 is shorter than the first distance L1. Further, the third distance L3 is shorter than the second distance L2.

The control device 18 controls the spray device 19 and the shutter 7 by using the output signals from the first sensor 14, the second sensor 16, and the third sensor 17. Specifically, the control device 18 outputs various control signals to the spray device 19 and the shutter 7. Details of the operation of the control device 18 will be described later.

As shown in FIG. 3, the spraying device 19 atomizes liquid water and sprays it onto the truck 100 and the shutter 7. The spraying device 19 may be a liquid different from water having desired properties, or may spray water containing a liquid different from the water. The spray device 19 is arranged at a position separated from the outer wall 101a by a second distance L2. That is, the spray device 19 overlaps with the second sensor 16 and the gutter 12 in the vertical direction (Z direction). The spraying device 19 is arranged at least between the gutter 12 and the folded roof 11. According to this configuration, the water droplet WD dripping from the spray device 19 can be received by the rain gutter 12.

The spraying device 19 has a first spraying unit 21 that sprays water W onto the truck 100, and a second spraying unit 22 that sprays water W onto the shutter 7. The operations of the respective spraying units are independent of each other, and while operating only the first spraying unit 21 to spray water W on the truck 100, the operation of the second spraying unit 22 is stopped and the water W on the shutter 7 is stopped. It is possible to operate without spraying, and vice versa. It is also possible to operate the first spray unit 21 and the second spray unit 22 at the same time to spray water W on the track 100 and the shutter 7. The operation of the spray device 19 is based on the control signal transmitted from the control device 18. The operation of the spray device 19 may be controlled by an operator's operation without being controlled by the control device 18.

The first spraying unit 21 for spraying water W toward the track 100 has a first main pipe 23 extending along the Y direction and a plurality of first nozzles 24 arranged apart from each other in the Y direction. Mist-like water W is discharged from the open end of the first nozzle 24. Further, a rain gutter 12 is located directly below the opening end of the first nozzle 24. That is, when the water droplet WD drips from the open end of the first nozzle 24, the water droplet WD is received by the rain gutter 12. The direction in which the first nozzle 24 faces is between the rain gutter 12 and the second folded roof 11B. This angle may be appropriately set depending on the height from the ground to the spraying device 19, the capacity of the spraying device 19, and the like. Further, the description of "spraying water W toward the truck 100" in the present embodiment does not require changing (tracking) the spraying direction at any time in response to the moving truck 100. It may be sprayed toward the track 100 at a certain point in time, and the spraying direction may be fixed. Further, it may be configured to track the moving track 100.

The second spraying unit 22 that sprays water W toward the shutter 7 has a second main pipe 26 that extends along the Y direction, and a plurality of second nozzles 27 that are arranged apart from each other in the Y direction. Mist-like water W is discharged from the open end of the second nozzle 27. Further, a rain gutter 12 is located directly below the opening end of the second nozzle 27. That is, when water W drips from the open end of the second nozzle 27, the water W is received by the rain gutter 12. The direction in which the second nozzle 27 faces is between the gutter 12 and the first folded roof 11A.

Further, the first spray unit 21 will be described in detail with reference to FIG. As described above, the first nozzles 24 are arranged apart from each other in the Y direction. Here, the orientation of the first nozzle 24 is different for each of the first nozzles 24 when viewed from the X direction. Specifically, the first nozzle 24 arranged in the region R2 corresponding to the width of the truck 100 or the carry-in inlet 2 is parallel to the X direction. On the other hand, the first nozzle 24 arranged in the region R3 outside the width of the truck 100 or the carry-in inlet 2 is inclined with respect to the X direction. That is, the first nozzle 24 is configured to spray water W toward the side surface 102c of the container 102.

Hereinafter, a method of entering the building according to one embodiment of the present invention will be described. The following description also includes a description regarding the operation of the control device 18. As shown in part (a) of FIG. 5, the truck 100 moves backward toward the building 101 with the container door 103 of the container 102 facing the building 101. In the state shown in the part (a) of FIG. 5, the track 100 is not detected by any of the first sensor 14, the second sensor 16, and the third sensor 17.

As shown in part (b) of FIG. 5, when the truck 100 moves backward, the rear end 102a of the container 102 moves below the first sensor 14. Then, the first sensor 14 transmits a first signal indicating that the object (track 100) is positioned below to the control device 18. The first signal may be a pulse-shaped signal or a step-shaped signal. The control device 18 that has received the first signal transmits the first spray start signal to the spray device 19. Upon receiving the first spray start signal, the spray device 19 starts spraying water W from the first spray unit 21 toward the truck 100 (first step S1). Further, the spraying device 19 starts spraying water W from the second spraying unit 22 toward the shutter 7 of the carry-in inlet 2.

As shown in part (c) of FIG. 5, the truck 100 moves further backward to approach the carry-in entrance 2. While the rear end 102a of the container 102 is located between the first sensor 14 and the second sensor 16, the spraying device 19 continues the water W spraying operation (second step S2).

As shown in the portion (a) of FIG. 6, the rear end 102a of the container 102 moves to the lower side of the second sensor 16 as the truck 100 further moves backward. Then, the second sensor 16 transmits a second signal indicating that the object (track 100) is positioned below to the control device 18. The second signal may be a pulse-shaped signal or a step-shaped signal. The control device 18 that has received the second signal transmits the first spray stop signal to the spray device 19. Upon receiving the first spray stop signal, the spray device 19 stops spraying water W from the first spray unit 21 and the second spray unit 22 (third step S3).

As shown in part (b) of FIG. 6, the control device 18 that has received the second signal further transmits a shutter release signal to the shutter 7. The shutter 7 that receives the shutter release signal opens the building opening 6 (fourth step S4). The timing at which the shutter release signal is transmitted may be the same as the transmission of the first spray stop signal, or may be after a predetermined time has elapsed after the transmission of the first spray stop signal. Further, the opening operation of the shutter 7 may be performed based on the shutter operation of the operator.

As shown in part (c) of FIG. 6, the operator opens the container door 103 after the spraying of water W from the spraying device 19 is stopped (fifth step S5). Here, since the container door 103 is generally a double door type, it is necessary to provide a predetermined distance between the rear end 102a of the container 102 and the carry-in entrance 2. Therefore, the second distance L2 in which the second sensor 16 is provided can be said to be a distance at which the container door 103 can be opened / closed, and further can be said to be a distance longer than the distance at which the container door 103 can be opened / closed.

As shown in part (a) of FIG. 7, after opening the carry-in port 2 and opening the container 102, the truck 100 further moves backward, so that the opening port of the container 102 comes closer to the carry-in port 2. During this period, the spraying of water W from the spraying device 19 is stopped.

As shown in the part (b) of FIG. 7, the truck 100 further moves backward to connect the opening of the container 102 to the carry-in inlet 2 (sixth step S6).

As shown in part (c) of FIG. 7, the rear end 102a of the container 102 is located below the third sensor 17. Then, the third sensor 17 transmits a third signal indicating that the object (track 100) is positioned below to the control device 18. The third signal may be a pulse-shaped signal or a step-shaped signal. The control device 18 that has received the third signal transmits a second spray start signal to the spray device 19. Upon receiving the second spray start signal, the spray device 19 starts spraying water W from the first spray unit 21 (7th step S7). That is, the water W is not sprayed from the second spraying unit 22. In the state shown in part (c) of FIG. 7, the cargo loading / unloading operation is performed.

As shown in part (a) of FIG. 8, when the loading / unloading work of the load is completed, the worker advances the truck 100 (step 8 S8). During this time, the spraying device 19 continues to spray water W from the first spraying unit 21.

As shown in the portion (b) of FIG. 8, as the truck 100 further advances, the rear end 102a of the container 102 is separated from the lower part of the second sensor 16. At this time, the second sensor 16 outputs the fourth signal to the control device 18. The fourth signal may be a pulse-shaped signal or a falling portion of a step-shaped signal. The control device 18 that has received the fourth signal transmits a second spray stop signal to the spray device 19. Upon receiving the second spray stop signal, the spray device 19 stops spraying water W from the first spray unit 21 (9th step S9). Further, the control device 18 that has received the fourth signal transmits a shutter closing signal to the shutter 7. The shutter 7 that receives the shutter closing signal closes the building opening 6. The timing at which the shutter closing signal is transmitted may be the same as the transmission of the second spray stop signal, or may be after a predetermined time has elapsed after the transmission of the second spray stop signal. Further, the opening operation of the shutter 7 may be performed based on the shutter operation of the operator.

As shown in part (c) of FIG. 8, the operator closes the container door 103 after the spraying of water W from the spraying device 19 is stopped (10th step S10).

By the above steps S1 to S10, the work of loading and unloading the load on the truck 100 is completed.

According to the above-described embodiment, when the truck 100 approaching the carry-in inlet 2 is detected by the first sensor 14, the spraying device 19 starts spraying water W toward the truck 100. This spraying continues until the track 100 is detected by the second sensor 16. According to the spraying of the water W, the mist-like water W adheres to the blades of the insects perched on the truck 100, so that the insects can be removed from the truck 100. In addition, since it becomes difficult for insects with water W attached to the blades to fly, it is possible to prevent the insects from flying and invading the interior of the building 101 after the carry-in entrance 2 is opened (third step: S3). Will be possible. Therefore, it is possible to prevent insects from invading when entering and exiting the building 101.

In the first step S1, the spraying device 19 further starts spraying the water W toward the carry-in inlet 2, and in the second step S2, the spraying device 19 continues to spray the water W toward the truck 100 and the spraying device. 19 continues to spray water W toward the carry-in port 2. Insects can not only perch on truck 100, but also on carry-in entrance 2. According to these first step S1 and second step S2, water W is sprayed on the insects perched at the carry-in port 2. Then, it becomes possible to remove the insects from the carry-in entrance 2 and prevent the insects from flying out from the carry-in entrance 2. Therefore, it is possible to further suppress the invasion of insects when entering and exiting the building 101.

The truck 100 is a vehicle equipped with a container 102 having a container door 103 at the rear end 102a. In the first step S1, when the first sensor 14 detects the rear end 102a of the container 102, the spray device 19 uses the container. The door 103 is further provided with a fifth step S5 of spraying water W and opening the container door 103 after the third step S3. By the first step S1 and the second step S2, it becomes possible to remove the insects stuck in the container door 103 and prevent the insects from flying out from the container door 103. Then, in this state, since the container door 103 is opened, it is possible to prevent insects from invading the container 102.

In the method of entering the building 101, after the fourth step S4 and the fifth step S5, after the sixth step S6 for connecting the truck 100 to the carry-in entrance 2, and after the sixth step S6, from the carry-in entrance 2 to a predetermined flow line. When the track 100 is detected to be located below the third sensor 17 by the third sensor 17 provided along the third distance L3, which is shorter than the second distance L2, the upper surface 102b of the container 102 The spraying device 19 further includes a seventh step S7 in which the spraying device 19 sprays water W toward the upper surface 102b of the container 102 so as to form a mist region R4 that prevents the entry of insects between the roof structure 3 and the roof structure 3. According to the seventh step S7, while the article is being carried from the container 102 to the building 101, the mist region R4 suppresses the insects from approaching the carry-in entrance 2. Therefore, it is possible to further prevent insects from invading the building 101 when entering and exiting the building 101.

The method of entering and exiting the building 101 is as follows: after the seventh step S7, the eighth step S8 for moving the truck 100 in a direction away from the carry-in entrance 2 along the flow line, and after the eighth step S8, the second sensor 16 Further includes a ninth step S9 in which the spraying device 19 stops spraying the liquid when the truck 100 is detected, and a tenth step S10 in which the container door 103 is closed after the ninth step S9. According to the 9th step S9 and the 10th step S10, the invasion of insects into the container 102 to be closed can be suppressed.

[Second Embodiment]
Next, the case where the moving body is a person will be described. Even when the moving body is a person, the configuration of the entrance structure 1A is the same as that of the first embodiment except that the building entrance is the entrance 2A for people.

As shown in part (a) of FIG. 9, the person 200 advances toward the entrance 2A. In the state shown in part (a) of FIG. 9, the person 200 is not detected by any of the first sensor 14, the second sensor 16, and the third sensor 17.

As shown in part (b) of FIG. 9, as the person 200 moves further forward, the person 200 moves below the first sensor 14. Then, the first sensor 14 transmits a first signal indicating that the person 200 is located below to the control device 18. The control device 18 that has received the first signal transmits the first spray start signal to the spray device 19. Upon receiving the first spray start signal, the spray device 19 starts spraying water W from the first spray unit 21 toward the person 200 (first step S1A). Further, the spraying device 19 starts spraying water W from the second spraying unit 22 toward the shutter 7A of the carry-in inlet 2. Although the shutter 7A is shown as an example of the closed portion, the closed portion may be a door or the like as described in the first embodiment.

As shown in part (c) of FIG. 9, the person 200 moves further forward to approach the entrance 2A. While the person 200 is located between the first sensor 14 and the second sensor 16, the spraying device 19 continues the spraying operation of the water W (second step S2A).

As shown in the part (a) of FIG. 10, the person 200 moves further below the second sensor 16. Then, the second sensor 16 transmits a second signal indicating that the person 200 is located to the control device 18. The control device 18 that has received the second signal transmits the first spray stop signal to the spray device 19. Upon receiving the first spray stop signal, the spray device 19 stops spraying water W from the first spray unit 21 and the second spray unit 22 (third step S3A).

As shown in part (b) of FIG. 10, the control device 18 that has received the second signal further transmits a shutter release signal to the shutter 7A. The shutter 7A that receives the shutter release signal opens the building opening 6A (fourth step S4A).

As shown in part (c) of FIG. 10, the person 200 enters the building 101 by further advancing. After that, the shutter 7A is closed.

Also in the second embodiment described above, the spray device 19 sprays water W on the person 200 who is about to enter the building 101. By this spraying, it becomes possible to remove the insects perched on the person 200.

The present invention has been described in detail above based on the embodiment. However, the present invention is not limited to the above embodiment. The present invention can be modified in various ways without departing from the gist thereof.

For example, in the above embodiment, the opening operation of the shutters 7 and 7A is based on the output signal of the second sensor 16. However, the opening operation of the shutters 7 and 7A may be performed at a desired timing as long as it is a period after the spraying is stopped. That is, it may be performed by using another signal or the like as a trigger regardless of the output signal of the second sensor 16. For example, the shutter 7 may be released after the track 100 is connected to the track berth 1. In this case, the output signal of the third sensor 17 can be used, or the operator may manually open the shutter 7 from the inside. At this time, the insect repellent area R1 can prevent insects from invading the interior of the building 101 from the carry-in entrance 2 when there is a gap in the carry-in entrance 2.
