Description

  The present invention relates to a method and an apparatus for detecting a protruding portion of a vehicle entering a mechanical parking device, and more specifically, the vehicle protrudes from either the left or right or both sides of the vehicle due to forgetting to fold the door mirror. The present invention relates to a method and an apparatus for detecting a protruding part of a vehicle that enters a mechanical parking device used for detecting that the vehicle is in a warehousing operation and notifying a user.

  As a parking device for efficiently parking a vehicle on a limited site, an elevator-type mechanical parking device that raises and lowers the cage like an elevator, and a cage that circulates vertically or horizontally There are circulation type mechanical parking devices, etc., and these mechanical parking devices have a lower entry system that allows entry from the entrance provided in the lower part of the building, and parking spaces on the ground and underground An intermediate entry system that distributes and enters or exits from an entrance provided at an intermediate position, and an upper entry system that installs a parking space in the basement and enters and descends from the top. There is what I did.

  On the other hand, in recent years, the mechanical parking device as described above has been developed in order to enable parking of vehicles having various shapes and vehicles having different heights in one parking device. The width of the loading section is also widened so that the distance between the wheels can be accommodated for vehicles with a high height, and the pallet for loading the vehicle can be loaded with a wide variety of vehicles with different dimensions between the left and right wheels. It is also adapted to store vehicles with different vehicle widths.

  Therefore, when the vehicle to be stored in the mechanical parking device as described above is to be stored on the pallet for loading the vehicle, the vehicle to be stored in the left-right direction is wide because the width of the storage portion on the pallet is wide. It is possible to get in even if one of them is too far, and as a result of getting in, there is a case where the vehicle is leaning to one of the left and right directions on the pallet without being noticed by the user of the vehicle. There is also a possibility that a vehicle full of the pallet width can be put in. In such a case, if the door mirror is forgotten to be folded, the door mirror that remains open may protrude from the outward position on both the left and right sides of the pallet, which is the allowable range of the mechanical parking device.

  As described above, when a vehicle is placed on the pallet with the protruding portion from the garageable range of the mechanical parking device, the vehicle is placed on the pallet as in the lower placing method and the intermediate placing method described above. When the operation of raising the pallet or the operation of lowering the pallet is started after entering the warehousing operation, the protruding part such as the protruding door mirror is connected to a machine such as a car storage shelf of the mechanical parking device. There is a risk of contact with other vehicles already in the warehouse and causing damage.

  Therefore, in the past, contrivances have been made to prevent such a situation in the past, and various measures have been proposed.

  FIG. 3 and FIG. 4 show an example, and a pair of front and rear rack devices 3 are stood and housed in the building 1 so as to open the elevator platform passage 2, and between the front and rear pair of rack devices 3. In a three-dimensional parking garage in which a lift 6 and a vehicle transfer device provided on the lift 6 are provided in a pit 5 below the floor 4 of the floor 4, A transmitter 9 for transmitting signals such as light, radio waves, and sound waves that pass above and outside the vehicle 8 is provided on the left side of the elevator platform passage 2 of each of the front and rear rack devices 3, and signals from these transmitters 9 are transmitted. The receiver 10 for receiving is configured on the right side of the rack device 3. As a result, when the car 8 that has entered the vehicle is placed on the pallet in a state of protruding from the set position on the lifting platform 6, the door / mirror 11 of the vehicle 8 lifted by the lifting platform 6 causes light / radio waves emitted from the transmitter 9.・ Since signals such as sound waves are cut off, it can be detected that the car 8 that has entered the vehicle has a protruding part from the set position of the lift 6 and at the same time, the lift is raised by the operation of the sensor due to the above signal being cut off. 6 is designed to be brought to an emergency stop (see, for example, Patent Document 1).

  In addition, the applicant of this patent also operated the parking device when the warehousing operation ended in the vertical circulation parking device when the door mirror of the warehousing vehicle was left open without being folded. In addition, when the pallet with the warehousing vehicle reaches the installation position of the phototube sensor while moving along the cage vertical movement path, it detects that the door mirror protrudes and also makes the cage move emergency stop. A patent application has been filed (Japanese Patent Application No. 2007-268213).

JP-A-6-323031

  However, the invention relating to the one described in Patent Document 1 and the patent application filed by the present patent applicant is of a single optical axis type that passes a signal such as light in the horizontal direction, and is diverse. Because the position of door mirrors mounted on vehicles with different shapes and vehicles of different heights varies, it is impossible to detect the protrusion of all the door mirrors etc. of the car during warehousing operation with only one optical axis It can be said.

  For this reason, in the case of the one described in the above-mentioned Patent Document 1 or the prior application of the present applicant, the protrusion from the garageable range is detected in the process of moving the vehicle that has finished the warehousing operation to the parking space position. That is what I am trying to do.

  Therefore, when detecting the protrusion of a door mirror etc. in the process of moving the vehicle that has finished the warehousing operation upward, install a transmitter and a receiver at a position higher than the door mirror position of the vehicle entered at the entrance. In addition, in the case of underground parking where the incoming car is moved downward from the entry position, the transmitter and the receiver are installed at a position lower than the door mirror position of the vehicle entering from the entrance. In the process of moving the machine, the projection of the door mirror, etc. is detected, and when the projection is detected, the parking device machine is emergency stopped, and the projection part contacts the machine or other vehicle as described above. I don't want to do that.

  However, in the above-mentioned conventional device, after the warehousing operation is finished and the user exits from the entrance door of the parking device, the protruding portion such as the door mirror of the vehicle is transmitted from the transmitter while the machine is moving. Therefore, it is not detected during the warehousing operation before the user leaves.

  In addition, in order to restore the emergency stopped machine, it is necessary to check the protruding part and eliminate the protruding part, but since the recovery work is after the user has left, The problem is that it is not possible for the person to eliminate the cause of the emergency stop, and it is necessary for a person in charge to urgently go to the site to restore the machine, and forget to fold the door mirror, etc. There is.

  In order to eliminate such a problem, a multi-optical axis sensor is attached so that the protruding portion is detected during the warehousing operation of placing vehicles of various shapes or vehicles of different heights on the pallet. However, it is necessary to have a sensor on the light emitting side and a sensor on the light receiving side, and it is difficult to secure the mounting position especially when trying to attach the sensor on the light receiving side to the entrance. There is a problem that there is.

  Therefore, the present invention allows the user to be aware of the protrusion of the door mirror from the allowable storage range due to forgetting to fold the door mirror during the warehousing operation of the vehicle, and detecting it before the user leaves. At the same time, even if the size, shape, and height position of the door mirrors are different for vehicles of various shapes and different heights, they will enter the mechanical parking device that can reliably detect the protrusion from the garageable range. An object of the present invention is to provide a method and device for detecting a protruding portion of a vehicle.

  In order to solve the above-mentioned problems, the present invention provides a laser that is vertically oriented at the boundary portion of the garageable range that is the outer position of both the left and right sides of the pallet on which the vehicle that has entered from the entrance of the mechanical parking device is placed. A vehicle that enters a mechanical parking device that irradiates light in one direction in parallel and detects a protruding portion from the entrapped range during a warehousing operation of placing the vehicle on a pallet from the entry port. Further, in the above method, the laser beam is irradiated in one direction from the front of the vehicle on the far side of the building facing the entrance of the mechanical parking device or the upper part of the center of the pallet. This is the detection method.

  In addition, in the mechanical parking device in which a vehicle is placed on the pallet from the entrance of the building and moved up and down with the pallet to be parked, the pallet is placed at the required positions in the building on the left and right sides of the pallet. Installation of a detection sensor that irradiates a laser beam that spreads in a flat plane in the vertical direction through the boundary of the possible range, connects the detection sensor to a display device, and enters the vehicle on the pallet A protruding portion detection device for a vehicle entering a mechanical parking device, characterized in that the protruding portion is detected and displayed during operation. Further, in the above configuration, the detection sensor is placed in a building. On the inner surface of the rear side wall of the building facing the mouth, the position is higher than the higher vehicle and on the left and right sides, or on the left and right sides of the central part of the pallet Installed in position, the sensing device so as to irradiate the laser beam from one direction.

According to the protruding part detection method and apparatus for a vehicle entering the mechanical parking apparatus of the present invention, the following excellent effects are exhibited.
(1) Irradiate the laser beam that is a surface in the vertical direction in parallel to one side of the boundary of the garageable range that is the outer position of the left and right sides of the pallet on which the vehicle that has entered from the entrance of the mechanical parking device is placed. A method of detecting a protruding part of a vehicle entering a mechanical parking device, and detecting a protruding part from the above-mentioned garageable range during a warehousing operation of placing the vehicle on the pallet from the entry port, and entering the building A boundary part of the garageable range that is the outside position of the left and right sides of the pallet at a required location in the building in a mechanical parking device that is placed on the pallet from the mouth and lifted and parked together with the pallet. A detection sensor that irradiates a laser beam that spreads in a flat plane in the vertical direction is connected to the display device, and the vehicle is mounted on the pallet. Since it is a protruding part detection device for a vehicle entering a mechanical parking device, it has a configuration that detects and displays the protruding part during entering operation, so that the vehicle enters the pallet. During operation, it is possible to detect the protruding part from the storage range due to forgetting to fold the door mirror, etc., so that the user can be notified of the protrusion before leaving the user, and the user can immediately eliminate the protrusion. Can do. Thereby, it will not lead to an emergency stop of a machine, and it will be possible to eliminate a request for a restoration work from a staff member.
(2) Since the protruding portion can be detected in the range of the flat surface of the laser beam, even if there is a single optical axis in a wide variety of shapes or vehicles of different heights, even if it is out of the detection range and can not be detected What protrudes from the possible range can be reliably detected.
(3) In the configuration of (1) above, the laser beam is irradiated in a planar shape in one direction from the front of the vehicle on the far side of the building facing the entrance of the mechanical parking device or from the top of the center of the pallet. And a detection sensor at a position higher than a vehicle with a high vehicle height on the inner surface of the rear side wall of the building facing the entrance of the building and on both the left and right sides of the central portion of the pallet in the vehicle entry direction. By installing the detector at the upper position and irradiating the laser beam from one direction, the detection sensor can be detected only from one side without using two light emitting and receiving, and installation is easy. Moreover, it can be easily attached not only to a newly installed parking apparatus but also to an existing parking apparatus.

It is the front view seen from the entrance side which shows the outline | summary of the state applied to the elevator-type mechanical parking apparatus as one Embodiment of this invention. It is a schematic side view of FIG. It is a side view of the entrance part of the conventional elevator system parking apparatus. It is the IV-IV arrow line view of FIG.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 and FIG. 2 show a case where the present invention is applied to an elevator-type mechanical parking apparatus and a lower entry system, and an entrance 13 is provided at the lower part of the front side wall 12a. Laser light 16 having a flat surface in a vertical direction at a required portion on the inner side surface of the rear side wall 12b of the building 12 that can be opened and closed by the door 14 (the inner side surface of the wall located on the front side of the entering vehicle). The detection sensor 15 is arranged so as to irradiate and detects the protruding portion of the door mirror or the like of the vehicle that is put on the pallet 18 for loading the vehicle on the cage 17 by the surface, and the protruding portion is detected. Are displayed on a sound or character display device (not shown) to inform the user.

  More specifically, a parking space is provided on both the left and right sides so as to sandwich the cage lifting / lowering part 19 provided in the central portion of the building 12, and the above-mentioned cage lifting / lowering is provided by installing the car storage shelves 20 in multiple stages at a required height interval. When the vehicle 21 is placed on the pallet 18 on the cage 17 supported so that the portion 19 can be moved up and down from the entrance 13, and the vehicle 21 is placed on the pallet 18 as shown in FIG. In the mechanical parking device in which the door 14 of the entrance 13 is closed and locked, and then the machine begins to move and raises the vehicle 21 together with the cage 17, in front of the building 12 where the entrance 13 is provided. A pair of laser beams 16 having a flat surface shape are irradiated on two inner surfaces of the rear side wall 12b of the building 12 facing the side wall 12a, and the light is reflected while scanning. The detection sensor 15 that is configured to detect a thing, so that the laser beam 16 is respectively installed so as to be irradiated in the direction of driving into port 13 as a vertical plane. Further, when a display device (not shown) for displaying an alarm sound or characters is installed in the building 12, and the detection sensor 15 detects and operates as a protrusion, a signal is sent to the display device and an alarm is generated. In addition to being emitted, a visible “overhang” character display is performed.

  The installation location of the detection sensor 15 is such that the laser beam 16 passes as a plane in the vertical direction at the boundary of the warehousing range, which is the outward position of the left and right sides of the vehicle 21 on the pallet 18 on the cage 17. As shown in the figure, even when vehicles of various shapes are put on the pallet 18, if there is a protruding part from the warehousing range, the positions of the two right and left parts are detected so that the protruding part can be detected. Even when a vehicle with a height is received and the height of the door mirror 22 is different, the height is set so that it can be detected as a surface.

  Since it is the said structure, as shown in FIG.1 and FIG.2, from the detection sensor 15 installed in two places of the inner side surface of the rear side wall 12b used as the back | inner side of the building 12, the building 12 with the entrance 13 is provided. The laser beam 16 is irradiated only in one direction toward the front side. The laser beam 16 is irradiated at a wide angle as a flat surface extending uniformly in the vertical direction as shown in the drawing, and is irradiated in parallel at two left and right locations. Thereby, when the vehicle 21 is put on the pallet 18 on the cage 17 and the warehousing operation is performed, the vehicle 21 put on the pallet 18 is offset by the pallet 18 and there is a protruding portion from the warehousing range. Since the protrusion is applied to the laser beam 16, the protrusion can be detected immediately and reliably. At this time, the protruding portion can be detected by the surface and can be detected by one detection sensor 15 from one direction, so that the protrusion can be reliably detected within the range of the surface.

  If it can be detected that the door mirror 22 or the like protrudes during the warehousing operation as described above, it is possible to notify the user by an alarm or a character display before the vehicle user leaves the entrance 13. . As a result, when the door mirror 21 protrudes, the user can know that he / she has forgotten to fold the door mirror, and can fold the door mirror 21 to eliminate the protrusion from the warehousing range.

  In the present invention, when the detection sensor 15 detects a protrusion, control can be performed so that the warehousing operation cannot be terminated unless the protrusion is eliminated. In other words, when the detection sensor 15 is activated and an overhang is detected, an interlock mechanism is provided so that the door 14 is not closed even if the door 14 of the entrance 13 is closed. Even if the user exits the door 14 without noticing that it is displayed on the display device in response to the command, the door 14 can be prevented from closing. In this way, even if the user makes a mistake that the vehicle has been placed on the pallet 18 and has finished the warehousing operation, the machine cannot be moved, so that the user cannot enter the warehousing. Become.

  The present invention is not limited to the above-described embodiment. For example, the detection sensor 15 is attached to the inner side surface of the rear side wall 12a of the building. In the case where the cage is moved downward from the entrance and parked, it may be attached to the ceiling instead of the rear side wall 12a of the building 12, and in this case, on the pallet 18 What is necessary is just to make it irradiate a laser beam from the upper direction of the front-back direction of the vehicle put into the warehousing range from the upper direction to the lower direction, and that the present invention can be applied to all mechanical parking devices. Of course, various changes can be made without departing from the scope of the present invention.
