Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a vehicle AT transmission in-gear which determines whether an AT transmission of a vehicle on a vehicle conveyance line is in a neutral state or an in-gear state. It relates to a determination device.

[Conventional technology]

A conventionally known slat conveyor that transports a vehicle in a wheel-locked state is such that the front wheel of the slat is pressed forward from the rear by the forward movement of the slat at the upper end of the slat and the vehicle is driven by the slat to thereby slat the vehicle. The vehicle is transported on a conveyor, and a wheel locking member for locking a wheel is provided on the upper surface of the slat one by one on the upper surface of the slat for transporting one vehicle.

[Problems to be solved by the invention]

For example, in a test line where the engine of the vehicle is operated and the vehicle flows unattended, the engine sound of the completed vehicle is checked, and the exhaust gas is inspected, etc., the mission of the vehicle to be conveyed is set to the neutral state. Is an absolute requirement.

By the way, in the case of a manual transmission vehicle, after the operator drives the vehicle on the slat conveyor, the engine is stopped when the clutch is released if the gear is in the in-gear state when returning to the neutral position and getting off the vehicle. For example, the worker can sense that the vehicle is in gear, but in the case of an AT transmission vehicle, it is possible to leave the vehicle with the engine running even if the vehicle is in gear, The operator may not be able to sense the in-gear state due to a mistake or the like.

If the vehicle inspection is performed in the above-described AT transmission vehicle while the vehicle is in gear, it is conceivable that the vehicle slowly advances on the slat conveyor and collides with the preceding vehicle in spite of the idling state.

Further, in order to prevent a collision with the front vehicle, a pair of wheel locking members are provided so as to clamp the wheels with appropriate play, thereby preventing an unmanned vehicle in an in-gear state from moving forward. Although it is possible to visually check whether the vehicle's mission is in gear or neutral, open the bonnet and adjust the throttle for vehicles that emit abnormal engine noise As a result, there is a case where it is necessary to increase the number of revolutions of the engine to perform the inspection, and at this time, a problem that the vehicle suddenly starts is considered.

The present invention has been made in view of solving such a problem, and it is possible to determine whether an AT transmission of a vehicle on a vehicle transport line is in a neutral state or an in-gear state. It is an object of the present invention to provide a determination device having a simple structure.

[Means for solving the problem]

In order to achieve the above object, the present invention provides at least one pair of vehicles for transporting one vehicle in the slat traveling direction on the slats of the slat conveyor that transports the vehicle while maintaining a distance that does not simultaneously contact the wheels of the vehicle. A wheel locking member provided, a wheel locking member position checking means for checking whether or not the wheel locking member moving with the operation of the slat conveyor has reached a predetermined position; and Wheel confirmation means for confirming whether or not the wheel exists, and a wheel for the wheel engagement member when the wheel engagement member reaches a predetermined position, which is confirmed by the wheel identification means and the wheel engagement member position confirmation means. And warning means for determining whether the AT transmission of the vehicle is in a neutral state or an in-gear state from the position, and issuing a warning.

[Operation] When the AT transmission of the vehicle is in the in-gear state, the wheels advance by rotating and driving, and the wheels come to a position where they are stopped by a front wheel locking member which is not normally seen in a neutral state. When the wheel locking member reaches a predetermined position due to the rotation drive of the slat conveyor, the wheel locking member position confirmation means confirms that fact, and together with the fact that the wheel is stopped by the front wheel locking member. The wheel confirmation means confirms and a warning is issued by the warning means.
