Vehicular door closing-inspection apparatus and vehicular door closing-inspection method

A door closing-inspection method for a vehicle, by a door closing-inspection apparatus for a vehicle provided with:

• a barcode reader arranged at an upstream side of a transferring conveyer in a finished vehicle inspection line which inspects a finished vehicle while transferring the finished vehicle,
• a door-closing device arranged on each of two lateral sides of an axis (L) of the transferring conveyer of the finished vehicle inspection line which inspects a finished vehicle while transferring the finished vehicle, wherein the door-closing devices are arranged downstream of the barcode reader and closes each of the opened doors of the finished vehicle at a predetermined velocity;
• a first pair of vehicular body detection devices arranged downstream of the door-closing devices;
• a pair of door closing detection devices arranged symmetrically on opposite lateral sides of an axis (L) of the transferring conveyer and in positions downstream of and adjacent to the first pair of vehicular body detection devices in a conveying direction of the apparatus, wherein the door closing detection devices detect a degree of closing of the closed doors;
• two pairs of second vehicular body detection devices arranged symmetrically on the opposite lateral sides of an axis (L) of the transferring conveyer and in positions downstream of the pair of door closing detection devices, and
• a controller connected to the first pair of vehicular body detection devices, the two pairs of second vehicular body detection devices, the door-closing devices, and the door closing detection devices, the door closing-inspection method for a vehicle comprising steps in the following sequence:
• reading a barcode indicating information about the vehicle;
• determining that a distance between the doors and the door closing detection devices have reached a predetermined distance based on a result of a measurement of a distance from each of the door closing detection devices,
• closing the doors by activating the door-closing devices to abut on a pressed face which is located below a position of a door outer handle of each of the doors, and to horizontally apply a pressing force to the pressed face at a predetermined velocity,
• receiving detection information from the two pairs of second vehicular body detection devices disposed upstream of the door closing detection devices;
• and
• detecting the degree of closing of each of the doors by activating the door closing detection devices at the same time as the two pairs of the second lightening and light-receiving devices detect the vehicular body of the finished vehicle.
