Thereby, it is possible to minimize the entry of dust from the outside, moisture in the rain, and the like into the inside of the entry / exit door.

<Wheel abnormality detection means 13>
The wheel abnormality detection means 13 includes a plurality of rollers 51-1 to 51-5 as rotating members that are rotatable when the two-wheeled vehicle 40 passes as shown in FIGS. Belt members 53-1 to 53-5 wound around rollers 51-1 to 51-5 and the shaft portion 52, a rotary encoder 54 as rotation detecting means for detecting the rotation angle of the shaft portion, and an abnormality detecting means 55 It is comprised so that. Note that the number of rollers 51 in this embodiment is an example, and is not particularly limited.

  The rollers 51-1 to 51-5 are so-called free rollers having no driving means. Further, the rollers 51-1 to 51-5 rotate when they contact the front wheels 41 and the rear wheels 41 during the conveyance of the two-wheeled vehicle 40 shown in FIG. Moreover, the rotational force in each roller 51-1 to 51-5 is transmitted to the shaft portion 53 by belt members 53-1 to 53-5 wound around the end portions of the respective rollers 51-1 to 51-5. The rotary encoder 54 detects the transmitted rotation angle of the shaft portion 52.

  That is, the rotary encoder 54 detects the number of rotations of the shaft portion 52 at a predetermined time. The rotary encoder 54 detects the rotation angle that is totaled by the respective rotations from the rollers 51-1 to 51-5 obtained by the shaft portion 52. The rotary encoder 54 can measure not only the rotation angle but also the speed when the motorcycle passes.

  The abnormality detection means 55 detects an abnormality of the wheel based on the rotation angle obtained by the rotary encoder 54. Here, a method for detecting wheel abnormality will be described. First, when the wheel to be measured can rotate normally, the roller 51 hardly rotates. In addition, when a foreign object such as an umbrella or a rod is sandwiched between the wheels, or when a foreign object such as a rope is entangled with the rotating shaft of the wheel, the wheel cannot rotate normally. The motorcycle is pulled in by the rotation. That is, as the wheels do not rotate, the rollers 51-1 to 51-5 rotate due to running resistance due to contact with the wheels. Therefore, the abnormality detection means 55 detects the abnormality of the wheel by acquiring the rotation angle of the roller 51 and comparing the magnitude with a preset threshold value.

  Specifically, the abnormality detection means 55 compares the rotation angle of the shaft portion 52 detected by the rotary encoder 54 with a rotation angle as a preset threshold value. The threshold value is set in advance for at least one of whether a wheel is locked, a foreign object is caught in the wheel, and a foreign object is wound around the wheel. It is possible to detect wheel abnormalities in a wide range from a state that does not move at all to a state that moves slightly but is not normal.

  The abnormality detection means 55 detects the number of rotations in a predetermined time by the rotary encoder 54 described above, so that the sudden rotation of the roller 51 due to vibration or the like is not detected as an abnormality, and the abnormality of the wheel is detected. Abnormalities can be detected with high accuracy.

  Moreover, in the loading / unloading apparatus 10 mentioned above, since the front wheel 41 is gripped and fixed by the clamping means of the transport device, when the front wheel 41 passes over the roller, it is determined that there is an abnormality because the wheel is fixed. There is a possibility that. Therefore, when the front wheel 41 passes, the detection by the abnormality detection means 55 is not performed, so that it is possible to determine the passage of only the rear wheel 42. Similarly, when the transport device grips and pulls on the rear wheel 42 of the two-wheeled vehicle 40, it can be set not to detect the rotation angle in the passage of the front wheel.

  Here, as a technique for preventing detection, measurement is not performed for a few seconds after the entrance / exit door 12 is opened, or the first detected rotation angle is determined to be the passage of the clamped front wheel. For example, there is a method of preventing the rotation angle from being detected.

  In addition, the abnormality detection determination method is not limited to this. For example, when the clamping means of the transport device grips the wheel frame instead of the wheel itself, both the front wheel 41 and the rear wheel 42 can rotate. In this case, an abnormality in both the front wheel 41 and the rear wheel 42 may be detected. Further, the respective rotation angles of the front wheel 41 and the rear wheel 42 may be detected, and it may be detected whether any of the wheels has an abnormality based on difference information of the respective rotation angles.

  In addition, when an abnormality is detected, the display input / output means 62 and the voice output means 63 provided in the operation unit 14 are used as notification means to display a message and output a voice, so that a user or administrator It is possible to quickly report that an abnormality has occurred.

  In addition, when the abnormality detection means 55 detects an abnormality, it is preferable that the two-wheeled vehicle pulled in halfway is returned to a predetermined set position of the original two-wheeled vehicle set unit 11 and the entry / exit door 12 is closed. Thereby, the user can promptly confirm the two-wheeled vehicle 40. Moreover, the damage accompanying the conveyance of the two-wheeled vehicle in a mechanical bicycle parking lot etc. can be prevented. In addition, it is possible to prevent problems such as failures and accidents in the loading / unloading device and the mechanical bicycle parking area.

<Operation unit 14>
Next, the operation unit 14 will be described. The operation unit 14 is a card reader 61 for inserting an IC card or the like used when limiting users as shown in FIG. 1, or a screen display for an administrator or user to operate loading and unloading. And a display input / output unit 62 including an operation panel having a touch panel function, and a voice output unit 63 for outputting voice and the like.

  Note that the card reader 61 may be one that inserts a card, or one that has a function of acquiring information in the card in a non-contact manner and rewriting it.

  Further, the operation unit 14 can display on the display input / output means 62 whether or not the bicycle parking lot can be used or a predetermined warning. The voice output means 63 is composed of a speaker or the like, and outputs the contents of operations such as warehousing procedures, availability of bicycle parking lots, predetermined warnings and warnings by voice.

  In the operation unit 14 in this embodiment, each of the components in the display input / output unit 62 and the voice output unit 63 has a function as an operation unit and a notification unit. Another configuration may be used.

  In addition, it is preferable that the wheel abnormality detection apparatus 13 mentioned above exists inside the entrance / exit door 12 seeing from the entrance. That is, the wheel abnormality detection device 13 is affected by water such as dust and rain water from the outside by being provided on the transport path along which the two-wheeled vehicle 40 is transported and at a position after passing the entry / exit door 12. Without abnormality, it is possible to detect the abnormality of the wheel of the motorcycle with high accuracy.

  In addition, the entry / exit device 10 may be further provided with a protective fence for limiting the entry direction of the two-wheeled vehicle 40, or may be provided with a vehicle length detection sensor or a vehicle width detection sensor for determining the vehicle in advance.

  As described above, the abnormality of the wheels can be detected with high accuracy by the above-described loading / unloading device 10.

Thereby, the front wheel 41 is fixed. Thereafter, the loading / unloading door 12 is opened, and the belt member 84 is moved in the reverse direction by the conveyance unit 70, whereby the wheels of the two-wheeled vehicle 40 are inserted between the pair of guide rails 85 provided in the conveyance device 70.

  At this time, the front wheel 41 and the rear wheel 42 pass through the rollers 51-1 to 51-5 of the wheel abnormality detection device 13 when the front wheel 41 and the rear wheel 42 are drawn from the two-wheeled vehicle set unit 11 to the transport device 70. Here, since the front wheel 41 is gripped, it is not necessary to detect abnormality. Therefore, the wheel abnormality detection device 13 sets in advance the time from when the entrance / exit door 12 is opened until the front wheel 41 passes over the rollers 51-1 to 51-5, and the roller 51 ( The rotation of the shaft portion 52) is not detected. This makes it possible to detect a necessary wheel abnormality without erroneous detection. Note that when the front wheel 41 is pulled in by the clamp portion 71, control such as lifting the front wheel 41 so that the front wheel 41 and the rollers 51-1 to 51-5 do not contact each other may be performed.

  Here, when an abnormality is detected by the abnormality detection means 55, the abnormality detection means 55 enters and exits the motorcycle 40 pulled in by the clamp portion 71 so as to return to the predetermined set position of the original motorcycle set portion 11. The control unit of the apparatus 10 is instructed, and the display input / output unit 62 and the audio output unit 63 provided in the operation unit 14 are used to display a message or output a voice that the abnormality has occurred.
