Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical parking system in which a vehicle is entered and exited at an entry/exit section.

Mechanical parking systems include types such as an elevator system and a vertical circulation system.

In these mechanical parking systems, a loading/unloading section is provided inside a building, and a loading/unloading port communicating with the loading/unloading section is provided on a wall surface of the building. An opening/closing door is provided at the entrance/exit (see Patent Document 1, for example).

In this type of mechanical parking device, when a start-up operation for entering/leaving is performed on the operation panel when entering/exiting, a machine related to pallet transport starts to operate, and the called pallet is placed on the storage shelf. It is transported from such a storage location to the loading/unloading section.

In the case of warehousing, the pallet to be called becomes an empty pallet, and when this empty pallet arrives at the warehousing/dispatching section, the door of the warehousing/dispatching port opens. In this state, the user drives the vehicle into the loading/unloading section through the loading/unloading opening and stops the vehicle on the empty pallet. Next, the user gets off the vehicle and exits the loading/unloading section through the loading/unloading opening.

On the other hand, in the case of delivery, the pallet to be called is the pallet loaded with the vehicle. In this state, the user enters the loading/unloading section through the loading/unloading opening, gets on the vehicle on the pallet, drives the vehicle, and exits the loading/unloading section through the loading/unloading opening.

After that, when the operation panel is operated to close the door, the mechanical parking device detects whether or not a person remains in the entrance/exit part by means of a detector, and then the door of the entrance/exit is closed.

After the entrance/exit door is closed, in the mechanical parking system, when the next activation operation is performed on the operation panel, or at a set timing, the machines related to pallet transport start to move and enter. The pallet in the delivery section is transported to the storage location and stored.

Therefore, when the entrance/exit is open, the entrance/exit part of the mechanical parking system becomes a boarding/exiting room for people to enter and exit the vehicle. This is the area where machine motions related to the transport of Machine operations that occur in the loading/unloading section in relation to pallet transport include, for example, pallet rotation by a turntable provided in the loading/unloading section, and transport of vehicles between the loading/unloading section and the storage location. These include the operation of a carrier such as a cage or lift, and the movement of a movable platform that interferes with the operation of a turntable or carrier.

Therefore, if the door of the loading/unloading entrance is closed while a person remains in the loading/unloading section, and the machine starts to operate, the person in the loading/unloading section will operate in the loading/unloading section. Machine contact is possible.

Further, during maintenance of the mechanical parking system, a maintenance worker may perform mechanical operations in the loading/unloading section while the operator is in the loading/unloading section.

Therefore, in the mechanical parking system, the operating range of the machine operating in the loading/unloading section, for example, the turning range of the pallet by the turntable, is indicated with yellow paint on the floor of the loading/unloading section. It is becoming more and more popular. In mechanical parking systems, areas that do not overlap with the operating range of the machines operating in the entering/exiting area and can therefore avoid contact with the operating machines can be indicated with green paint. It is now being done.

JP 2016-128648 A

However, the painted display on the floor of the entrance/exit section does not attract much attention because it always exists. In other words, the actual situation is that the user sees the painted display every time he enters the loading/unloading section, so that the user becomes accustomed to seeing it and it is difficult to stand out.

Therefore, conventionally, for a person left in the loading/unloading section when the door of the loading/unloading entrance is closed, the mechanical operation is performed without any special change in the visual information inside the loading/unloading section. is actually started.

Therefore, when the machine starts to operate in the entering/exiting section with the entering/leaving process of the vehicle, the present invention changes the visual information in the entering/exiting section before starting the operation of the machine. To provide a mechanical parking device capable of clearly indicating an area where there is a possibility of coming into contact with a machine operating in an entry/exit section and a place where contact with a machine operating in an entry/exit section can be avoided.

In order to solve the problem, the present invention provides an entrance/exit part, an entrance/exit communicating with the entrance/exit part, a door for opening/closing the entrance/exit, and the entry/exit part associated with the entry/exit process of the vehicle. A specific area is set in the entering/exiting section, and light of a color different from the illumination light of the entering/exiting section is emitted toward the specific area. means, and a control unit that gives a light irradiation start command to the light irradiation means when the operation of the machine is started after the door of the entrance/exit is changed from an open state to a closed state , The specific area includes a dangerous area in which there is a possibility of coming into contact with the machines operating in the loading/unloading section, and a retreat area in which contact with the machines operating in the loading/unloading section can be avoided, and the light irradiating means The color of the light emitted to the dangerous area is different from the color of the light emitted to the evacuation area by the light emitting means .

The light irradiation means is a projector.
Further, the specific area is set on the floor of the loading/unloading section.
Further, the control section gives a light irradiation start command to the light irradiation means before the operation of the machine is started.

According to the present invention, when the operation of the machine is started in the warehousing/dispatching section accompanying the warehousing/retrieving process of the vehicle, the visual information in the warehousing/dispatching section is changed before the operation of the machine is started. It is possible to clearly indicate areas where there is a possibility of coming into contact with machines operating in the warehouse, and places where contact with machines operating in the loading/unloading department can be avoided.

In the present embodiment, as shown in FIG. 2, the dangerous area 17 includes a location overlapping the movement range of the machine operating in the loading/unloading section 11, a location overlapping the rotation range of the pallet 10 by the turntable 9, and a location overlapping the cage 3 It is set in a place that overlaps with the operating range of If the loading/unloading section 11 is provided with a movable platform (not shown), a portion overlapping with the movable platform is also set as the danger zone 17 .

Although not shown, the floor 11a of the loading/unloading section 11 is more preferably configured such that the outer edge of the dangerous area 17 is painted, for example, with yellow paint. This is to clearly show the dangerous area 17 even when the projector 19 is not emitting light.

The evacuation place 18 is a place where it is possible to avoid contact with machines operating in the loading/unloading section 11 . In the present embodiment, as shown in FIG. 2, the evacuation place 18 is a place separated from both the turning range of the pallet 10 by the turntable 9 and the movement range of the cage 3 by a set distance. It is set at the four corners of the floor 11 a of the section 11 .

Although not shown, the floor 11a of the loading/unloading section 11 is more preferably configured so that the evacuation area 18 is displayed with paint, for example, green paint. This is to clearly indicate the evacuation area 18 even when the projector 20 is not emitting light.

The projector 19 irradiates the entire dangerous area 17 with light of a color different from that of the lighting equipment 16, for example, red light. In FIG. 2, the portion irradiated with the red light is indicated by hatching of dots.

Furthermore, as shown in FIGS. 1 and 2, even when the vehicle is placed on the pallet 10, the projector 19 projects a portion of the dangerous area 17 around the vehicle where the irradiation light cannot reach due to the shadow of the vehicle. They are provided at a plurality of locations on the side wall of the loading/unloading section 11 so as to prevent the occurrence of sagging. 1 and 2 show a configuration in which a projector 19 is provided inside the front wall 2a, the rear wall 2b, the left wall 2c, and the right wall 2d of the loading/unloading section 11. As shown in FIG.

In FIG. 2, the portion irradiated with the green light is indicated by diagonal hatching.

In FIGS. 1 and 2, projectors 20 are provided on both left and right sides of the inside of the front wall 2a of the loading/unloading section 11 and on both left and right sides of the inside of the rear wall 2b to individually irradiate each evacuation area 18 with light. showing.

The projector 19 and the projector 20 may continuously irradiate light, but may blink (flicker) in order to increase the change in visual information.

The control unit 21 controls the start and stop of the light display of the dangerous area 17 and the evacuation area 18 by the light irradiation from the projectors 19 and 20 .

After the door 14 of the loading/unloading port 13 is closed, the control unit 21 controls at least a set time before the time when the machine starts operating in the loading/unloading unit 11 for the first time, for example, 10 seconds before. At this time, the projector 19 and the projector 20 are provided with a function of giving a command to start optical display.

Further, when the operation of the machine in the loading/unloading section 11 is performed in a plurality of times after the door 14 of the loading/unloading port 13 is closed, the control section 21 starts each mechanical operation. A function may be provided to give a command to start the light display to the projector 19 and the projector 20 at a time before the set time before the time when the light display is performed.

For this reason, as shown in FIG. It cooperates with a control device 22 that gives operation commands to the device 6 .

When the control device 22 issues an operation command to the turntable 9 or the lifting device 6 of the cage 3 with the door 14 of the entrance/exit 13 closed, the control device 22 is operated at the time before the predetermined time from the time when the operation command is issued. , to the control unit 21, the information about issuing the operation command. The control unit 21 has a function of giving a light display start command to the projectors 19 and 20 when receiving this information from the control device 22 .

As a result, in the elevator-type mechanical parking device 1, with the door 14 of the entrance/exit 13 closed, the pallet 10 can be turned by the turntable 9 in the entrance/exit section 11 and the cage can be rotated in accordance with the entrance/exit process. 3, the dangerous area 17 is irradiated with red light or red flashing light from the projector 19 at the time before the set time from the start of the movement. Also, the evacuation area 18 is irradiated with green light or green blinking light from the projector 20 .

When the operation of the machine in the loading/unloading section 11 ends, or when the set elapsed time elapses after the operation of the machine in the loading/unloading section 11 starts, the control section 21 causes the projectors 19 and 20 to display light. It has a function to issue a command to terminate the

Although the control unit 21 is shown as being separate from the control device 22, it may be incorporated into the control device 22 as one of its functions.

Reference numeral 23 in FIG. 2 denotes a reflecting mirror used to confirm the position of the vehicle when the vehicle drives onto the pallet 10 arranged in the loading/unloading section 11 .

According to the mechanical parking apparatus of the present embodiment having the above configuration, when the vehicle entering/leaving process is performed, visual information in the entering/leaving unit 11 is displayed before the operation of the machine is started in the entering/leaving unit 11. Variations can be applied to define the danger areas 17 and the evacuation areas 18 .

Therefore, in the unlikely event that a person is left behind in the entrance/exit section 11 when the door 14 of the entrance/exit 13 is closed, the danger area 17 is indicated by red light to the person, and the evacuation area 18 is displayed. can be indicated by a green light.

For example, according to the JISZ9103 safety color standard, red indicates prohibition or danger, and green indicates a safe state. It is believed that the perception that red is dangerous and green is safe is generally widespread.

Therefore, when the door 14 of the entrance/exit 13 is closed, the person left behind in the entrance/exit section 11 leaves the danger area 17 shown in red and enters the evacuation area 18 shown in green. By doing so, it is possible to avoid contact with the machines operating in the loading/unloading section 11 accompanying the loading/unloading process.

When the projector 19 irradiates the red light onto the dangerous area 17, the projector 19 displays a message such as "Exit from the red part" that prompts the user to leave the dangerous area 17 indicated by the red light. A function of projecting onto the dangerous area 17 may be provided.

Similarly, when the projector 20 irradiates the evacuation area 18 with green light, the projector 20 displays a message prompting the evacuation area 18 indicated by the green light, such as "Please enter the green area." , a function of projecting to the evacuation place 18 may be provided.

Furthermore, in the entering/leaving unit 11, when the projector 19 irradiates the dangerous area 17 with red light, a voice output means (not shown) outputs a message such as "Please exit from the red area" by voice. You may make it Further, in the entering/leaving unit 11, when the projector 20 irradiates the evacuation area 18 with green light, a voice output means (not shown) outputs a message such as "Please enter the green area" by voice. It is of course possible to do so.

Further, in the present embodiment, the projector 19 and the projector 20 are used as optical display means for displaying the dangerous area 17 and the evacuation area 18 on the floor 11a of the entrance/exit section 11 with light of a color different from that of the lighting fixture 16. Since it is used, the floor 11a does not need to be provided with special equipment. Therefore, the mechanical parking system of this embodiment can be suitable for applying the present invention to existing mechanical parking systems.

The present invention may be applied to mechanical parking systems other than the circulation system.

Further, the mechanical parking system of the present invention is an elevator-type mechanical parking system in which only vehicles are transported from the loading/unloading section by a transport machine such as a cage (lift), and the vehicles are transferred to pallets or trays at the transport destination. It may also be applied to a mechanical parking device that is stored in a storage shelf.

The machines that operate in the loading/unloading section 11 include a turntable 9 for rotating the pallet 10, a conveying device such as the cage 3 and the cage 27, and a movable platform, depending on the type of mechanical parking device and the configuration of the loading/unloading section. It is of course possible to include the following.

In the mechanical parking system, the loading/unloading floor where the loading/unloading section 11 is provided is not limited to the lower part of the building 2, and the loading/unloading section 11 may be provided in the middle part of the building 2 in the vertical direction. Furthermore, for example, in the case of an underground mechanical parking system, the loading/unloading section 11 may be provided in the upper part of the building built underground.

Further, in each of the above-described embodiments, as an example of the timing for starting the illumination by the projectors 19 and 20, the time setting of 10 seconds before the time when the machine operates in the loading/unloading section 11 is exemplified, but it is limited to this. Of course, the time may be set to, for example, 5 seconds before or any other arbitrary time instead of the time.

In the mechanical parking system of the present invention, as shown in each of the above embodiments, it is preferable to clearly indicate both the dangerous areas 17, 17a and the evacuation areas 18, 18a by means of optical display means. A configuration in which only one of the evacuation locations 18 and 18a is indicated by an optical display means may be adopted.
