  When people or goods enter or leave the building, the building entrance is open to the outside environment. Then, when the entrance of the building is open, there may be a case where an insect near the entrance enters 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 that can prevent insects from entering the building when entering or leaving the building.

  In the method of entering a building according to one aspect of the present invention, when it is detected that a moving body that is approaching a building entrance provided in the building is located at a first reference position that is separated from the building entrance by a first distance, A first step of starting spraying toward the moving body from a spraying portion provided apart 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 Until the spraying portion continues to spray toward the moving body until it is detected that the second reference position is separated by the second distance, 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 process. Open the building entrance with the spraying section stopped spraying A fourth step.

  When the moving body approaching the building entrance is located at the first reference position, the spray unit starts spraying toward the moving body. This spraying is continued until the moving body is located at the second reference position. According to this spraying, since the mist-like liquid adheres to the insect blades that are stopped on the moving body, the insects can be removed from the moving body. In addition, since insects with liquid attached to the wings are difficult to fly, it is possible to prevent the insects from flying into the building after the building entrance is opened (third step). Therefore, it is possible to suppress insects from entering the building when entering or leaving the building.

  In one form, in the first step, the spray unit further starts spraying toward the building entrance, and in the second step, the spray unit continues spraying toward the moving body and the spray unit sprays toward the building entrance. You may continue. Insects can not only stop on moving objects, but also on building entrances. According to this process, it sprays with respect to the insect which has stopped at the building entrance. If it does so, it will become possible to remove an insect from a building entrance, and to control that an insect takes off from a building entrance. Therefore, it is possible to further suppress the insects from entering the building when entering and leaving the building.

  In one form, the moving body is a vehicle on which a container having a vehicle door at the rear end is mounted, and in the first step, when it is detected that the rear end of the container is at the first reference position, the spray unit is the vehicle door. You may further have the 5th process of spraying toward and opening a vehicle door after a 3rd process. By the first step and the second step, it is possible to remove the insects that have stopped on the vehicle door and to prevent the insects from flying off the vehicle door. In this state, the vehicle door is opened, so that insects can be prevented from entering the container.

  In one embodiment, the method of entering the building includes the sixth step of connecting the mobile body to the building entrance after the fourth step and the fifth step, and the mobile body is shorter than the second distance from the building entrance after the sixth step. When it is sensed that it is located at a third reference position separated by a third distance, the spraying portion sprays toward the upper surface of the container so as to form a region that prevents insects from entering the upper surface of the container. 7 steps may be further included. According to this step, the insects are prevented from approaching the entrance of the building by the area that prevents the insects from entering while the articles are being carried into the building from the container. Therefore, it is possible to further suppress the insects from entering the building when entering and leaving the building.

  In one embodiment, the method of entering the building is that after the seventh step, the eighth step of moving the moving body away from the building entrance, and after the eighth step, the moving body is positioned at the second reference position. When detected, the spray unit may further include a ninth step of stopping spraying and a tenth step of closing the vehicle door of the container after the ninth step. According to this process, insects can be prevented from entering the container to be closed.

  The entrance structure of the building which concerns on another form of this invention has an opening part and the closing part which can close an opening part, and the 2nd state where the opening was opened by the closing part and the opening was opened A building entrance that can be switched to each other, a roof portion that extends horizontally from the wall portion where the building entrance is provided, and a roof portion that is spaced apart from the wall portion by a first distance in the horizontal direction, A first sensor that determines the presence or absence of an object that exists below and a roof that is spaced apart by a second distance that is shorter than the first distance in the horizontal direction away from the wall, and the presence or absence of an object that exists below A first sensor for determining, a first spray unit that is provided on the roof so as to be spaced apart from the wall by a second distance in the horizontal direction, and sprays between the first sensor and the ground; Spraying in the spraying section using outputs of the sensor and the second sensor Start and and a control unit stopping.

Continues to spray toward the moving body, and when the moving body is detected by the second sensor, the spraying section can control to stop spraying. Therefore, it is possible to suppress insects from entering the building when entering the building.

  In another form, the entrance structure of the building may further include a second spray part that is provided on the roof part so as to be spaced apart from the wall part by a second distance in the horizontal direction and sprays toward the building entrance. . Insects can not only stop on moving objects, but also on building entrances. According to this structure, it sprays on the insect which has stopped at the building entrance. If it does so, it will become possible to remove an insect from a building entrance, and to control that an insect takes off from a building entrance. Therefore, it is possible to further suppress the insects from entering the building when entering the building.

  In another form, the entrance structure is provided on the roof portion so as to be separated from the wall portion by a third distance that is shorter than the second distance in the horizontal direction, and further includes a third sensor that determines whether or not an object exists below.

  DESCRIPTION OF EMBODIMENTS 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 denoted by the same reference numerals, and redundant description is omitted.

[First Embodiment]
First, the inlet structure will be described. As shown in FIG. 1, an example of an entrance structure is a so-called track berth 1. The truck berth 1 is a place where the truck 100 is stopped and loads are loaded and unloaded. The track berth 1 is provided in the building 101. The building 101 can include, for example, a food factory, a pharmaceutical factory, and a museum.

  The track berth 1 includes a carry-in entrance 2 (building entrance), a roof structure 3 (roof portion), and insect-proof equipment 4.

  The cargo is loaded and unloaded onto the truck 100 via the carry-in port 2. The carry-in entrance 2 may be provided at one place in one building 101, or a large-scale factory is provided with a plurality as shown in FIG. The carry-in port 2 is in an open state when performing the work of loading and unloading luggage, and is in a closed state when the work for unloading and unloading luggage is not performed. The carry-in entrance 2 has a building opening 6 (opening portion) and a shutter 7 (closing 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 port 2 can be switched between a closed state (first state) and an open state (second state). The closed portion is not limited to the shutter 7, and various configurations may be adopted as long as the entrance 2 can be switched between a closed state and an 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 an upper portion of the truck 100 when loading and unloading loads, and protects workers and trucks 100 engaged in loading and unloading from the 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 includes 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 load 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 away from the building 101 (X direction). That is, the beam steel frame 8 has a cantilever structure. The beam steel frames 8 are spaced apart from each other in a direction (Y direction) orthogonal to the extending direction (see FIG. 1). In addition, although the roof structure 3 illustrated in this embodiment has the five beam steel frames 8, the number of the beam steel frames 8 is not limited to this.

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

  The folded plate roof 11 is connected to a suspended steel frame 9 made of, for example, H steel. In other words, the folded roof 11 is arranged below the frame structure 13 (the beam steel frame 8 and the suspended steel frame 9) constituting the roof structure 3. In the framework structure 13, for example, a bird can nest on the flange of the suspended steel frame 9. However, in the roof structure 3 shown in FIG. 1 and FIG. 2, the frame structure 13 is not covered by the folded plate roof 11, so that the frame structure 13 is exposed to wind and rain. If it does so, it can suppress that a bird makes a nest in the suspended steel frame 9 grade.

  The roof structure 3 includes a first folded plate roof 11A and a second folded plate roof 11B. The first folded plate roof 11A on the building 101 side and the second folded plate 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, rainwater or the like can enter from the gap, so that a rain gutter 12 (saddle) is disposed below the gap.

  The insect repellent equipment 4 suppresses insects from entering the insect repellent area R1. The insect-proof area R <b> 1 prevents the insects from entering the building 101 from the carry-in port 2 when the carry-in port 2 is open. The insect-proof area R1 is set so as to surround the plurality of carry-in ports 2.

  The insect-proof 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 1st sensor 14, the 2nd sensor 16, and the 3rd sensor 17 judge whether an object exists in the lower part. 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) that exists below each of them. For example, the first sensor 14 emits an ultrasonic wave vertically downward. The time from when the ultrasonic wave is emitted until the reflected wave is detected differs between when the light is reflected on the floor 110 and when the light is reflected on the container 102 of the truck 100. Therefore, based on the time from when the ultrasonic wave is emitted until the reflected wave is detected, it is determined whether an object exists below the sensor. The first sensor 14, the second sensor 16, and the third sensor 17 are not particularly limited as long as it can determine whether or not an object exists.

  The first sensor 14, the second sensor 16, and the third sensor 17 are connected to a control device 18 disposed in the building 101. Accordingly, 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 side of the second folded roof 11B. The first sensor 14 is disposed at a position (first reference position) farthest from the outer wall 101a (wall portion) of the building 101. 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 disposed in the gap between the folded roofs 11. Furthermore, it can be said that the second sensor 16 is disposed in the vicinity of the leading edge (second reference position) of the first folded plate 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 a container door 103 (vehicle door) of the truck 100 described later is opened, a predetermined distance is required between the rear end 102a of the container 102 and the carry-in port 2. Based on this configuration, the second distance L2 may be a separation distance from the outer wall 101a necessary to open the container door 103.

  The third sensor 17 is attached to the back surface of the first folded plate roof 11 </ b> A above the carry-in entrance 2. That is, the third sensor 17 is disposed at a position (third reference position) closest to the outer wall 101a 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. The third distance L3 is shorter than the second distance L2.

  The control device 18 controls the spray device 19 and the shutter 7 using 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 spray device 19 sprays water, which is a liquid, on the truck 100 and the shutter 7 in the form of a mist. The spraying device 19 may be a liquid different from water having a desired property, or may spray water containing a liquid different from the water. The spraying device 19 is disposed at a position away from the outer wall 101a by the 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 disposed between at least the gutter 12 and the folded roof 11. According to this configuration, it is possible to receive the water droplet WD dripping from the spraying device 19 with the rain gutter 12.

  The spraying device 19 includes 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 spraying units are independent of each other, and only the first spraying unit 21 is operated to spray the water W onto the track 100, while the operation of the second spraying unit 22 is stopped and the water W to the shutter 7 is stopped. The operation of not spraying is possible and vice versa. Further, it is possible to spray the water W onto the track 100 and the shutter 7 by operating the first spray unit 21 and the second spray unit 22 simultaneously. The operation of the spray device 19 is based on a control signal transmitted from the control device 18. Note that the operation of the spraying device 19 may be controlled by an operator's operation without being controlled by the control device 18.

  The first spray unit 21 that sprays the water W toward the track 100 includes a first main pipe 23 that extends along the Y direction and a plurality of first nozzles 24 that are spaced apart from each other in the Y direction. Mist water W is discharged from the opening end of the first nozzle 24. A rain gutter 12 is located immediately below the opening end of the first nozzle 24. That is, when a water droplet WD drops from the opening 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 gutter 12 and the second folded roof 11B. This angle may be set as appropriate depending on the height from the ground to the spraying device 19, the ability of the spraying device 19, and the like. In addition, the description of “spraying water W toward the truck 100” in the present embodiment does not require that the spraying direction be changed (tracked) at any time corresponding to the moving truck 100. It suffices to spray toward the track 100 at a certain time, and the spraying direction may be fixed. Further, the moving track 100 may be tracked.

  The 2nd spraying part 22 which sprays the water W toward the shutter 7 has the 2nd main pipe 26 extended along a Y direction, and the several 2nd nozzle 27 arrange | positioned mutually spaced apart in the Y direction. Mist water W is discharged from the opening end of the second nozzle 27. A rain gutter 12 is located immediately below the open end of the second nozzle 27. That is, when water W is dripped from the opening end of the second nozzle 27, the water W is received by the gutter 12. The direction in which the second nozzle 27 faces is between the rain gutter 12 and the first folded plate roof 11A.

  Furthermore, the 1st spray part 21 is demonstrated in detail, referring FIG. As already described, the first nozzles 24 are arranged apart from each other in the Y direction. Here, the direction of the first nozzle 24 is different for each first nozzle 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 port 2 is parallel to the X direction. On the other hand, the first nozzle 24 disposed in the region R3 outside the width of the truck 100 or the carry-in port 2 is inclined with respect to the X direction. That is, the first nozzle 24 is configured to spray the water W toward the side surface 102 c of the container 102.

  Hereinafter, a method for entering a building according to an embodiment of the present invention will be described. Note that 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 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 102 a of the container 102 moves to 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 signal or a step signal. The control device 18 that has received the first signal transmits a first spray start signal to the spray device 19. Upon receiving the first spray start signal, the spray device 19 starts spraying the water W from the first spray unit 21 toward the track 100 (first step S1). Further, the spraying device 19 starts spraying water W from the second spraying part 22 toward the shutter 7 of the carry-in port 2.

  As shown in part (c) of FIG. 5, the truck 100 further moves backward to further approach the carry-in port 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 spraying operation of the water W (second step S2).

  As shown in part (a) of FIG. 6, when the truck 100 further moves backward, the rear end 102 a of the container 102 moves to below the second sensor 16. 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 signal or a step signal. Upon receiving the second signal, the control device 18 transmits a 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. Upon receiving the shutter opening signal, the shutter 7 opens the building opening 6 (fourth step S4). The timing at which the shutter opening signal is transmitted may be simultaneously with 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 operator's shutter operation.

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

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

  As shown in part (c) of FIG. 7, the rear end 102 a 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. Note that the third signal may be a pulse-like signal or a step-like signal. Upon receiving the third signal, the control device 18 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 (seventh step S7). That is, the spray of water W from the second spray unit 22 is not performed. In the state shown in part (c) of FIG. 7, the loading and unloading work is performed.

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

As shown in part (b) of FIG. 8, when the track 100 further advances, the rear end 102 a of the container 102 is separated from the lower side of the second sensor 16. At this time, the second sensor 16 outputs a 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. Upon receiving the fourth signal, the control device 18 transmits a second spray stop signal to the spray device 19. Upon receiving the second spray stop signal, the spray device 19 stops spraying the water W from the first spray unit 21 (9th step S9). The control device 18 that has received the fourth signal transmits a shutter closing signal to the shutter 7. Upon receiving the shutter closing signal, the shutter 7 closes the building opening 6. The timing at which the shutter closing signal is transmitted may be simultaneously with 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 operator's shutter operation.

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

  Through the above steps S1 to S10, the work of loading and unloading the cargo onto the truck 100 is completed.

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

  In the first step S1, the spray device 19 further starts spraying the water W toward the carry-in port 2, and in the second step S2, the spray device 19 continues to spray the water W toward the truck 100 and the spray device. 19 continues to spray water W toward the carry-in port 2. Insects can not only stop on the truck 100 but also on the entrance 2. According to these 1st process S1 and 2nd process S2, the water W is sprayed with respect to the insect which has settled in the carrying-in port 2. FIG. If it does so, it will become possible to remove an insect from the carrying-in port 2, or to suppress that an insect takes off from the carrying-in port 2. Therefore, it is possible to further prevent insects from entering when entering or leaving the building 101.

  The truck 100 is a vehicle on which a container 102 having a container door 103 is mounted at the rear end 102a. In the first step S1, when the first sensor 14 senses the rear end 102a of the container 102, the spray device 19 is used as a container. Water W is sprayed on the door 103, and after the 3rd process S3, it has 5th process S5 which opens the container door 103 further. By the first step S <b> 1 and the second step S <b> 2, it is possible to remove the insects that have stopped on the container door 103 and to prevent the insects from flying from the container door 103. In this state, since the container door 103 is opened, insects can be prevented from entering the container 102.

  In the method of entering the building 101, after the fourth step S4 and the fifth step S5, the sixth step S6 for connecting the truck 100 to the carry-in port 2 and the sixth flow from the carry-in port 2 to the predetermined flow line after the sixth step S6.

  As shown in part (a) of FIG. 10, when the person 200 further moves forward, the person 200 moves to 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. Upon receiving the second signal, the control device 18 transmits a first spray stop signal to the spray device 19. Upon receiving the first spray stop signal, the spray device 19 stops spraying the 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. Upon receiving the shutter opening signal, the shutter 7A 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 moving forward. Thereafter, the shutter 7A is closed.

Also in 2nd Embodiment mentioned above, the spraying apparatus 19 sprays the water W to the person 200 who is going to enter the building 101. FIG. By this spraying, it is possible to remove the insects that are stuck on the person 200.

  The present invention has been described in detail based on the embodiments. However, the present invention is not limited to the above embodiment. The present invention can be variously modified 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 the spraying is stopped. That is, it may be performed using another signal as a trigger regardless of the output signal of the second sensor 16. For example, the shutter 7 may be opened 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 can manually open the shutter 7 from the inside. At this time, when the carry-in entrance 2 has a clearance, the insect-proof area R <b> 1 can prevent insects from entering the building 101 from the carry-in entrance 2.
