Description

The present invention relates to a marking device that marks a mark by applying a predetermined paint to a predetermined position of a marking part.

For example, marking devices have been conventionally used to mark parts to be mounted on a vehicle with marks indicating the mounting direction and mounting position. As a conventional marking device, for example, as disclosed in Patent Document 1, a pen is moved up and down by a cam rotated by a rotary actuator, and a predetermined paint is applied by applying the pen tip to the marking part that is the object to be marked. Examples include things that are applied.

However, since the conventional marking device described above uses a pen to mark marking parts, it is necessary to frequently replace the pen when the marking device is used repeatedly over a long period of time. For this reason, the present applicant has a paint replenishment part for replenishing the coating surface of the application member, and by reversing and moving the application member, the paint replenishment part replenishes the coating surface with paint. At the same time, we have come to consider a marking device that applies paint to predetermined positions on marking parts to mark them.

However, it is conceivable to use a reversing mechanism of the stamping tool that allows the stamping part to be reversed and refilled with paint while stamping, but in that case, it is necessary to move the entire marking device to contact the marking part. Therefore, a relatively large driving force of the motor is required, and it is also necessary to ensure that the marking part has a contact surface with the marking device. Furthermore, if a stamping tool is simply used, the gap between the marking device and the placement surface becomes smaller when positioning and placing the marking component, which may impair work efficiency.

The present invention has been made in view of the above circumstances, and allows marking to be performed repeatedly over a long period of time, allows marking to be performed using a motor with a relatively small driving force, and also allows marking parts to be placed.
