(Embodiment 2)
Next, a moving object marking device according to Embodiment 2 of the present invention will be described.
In the marking device for a moving object according to the second embodiment, there are two marking units. However, the marking device for a moving object according to the present invention is not limited to two, and may be one or three or more.

FIG. 1 is a plan view showing an outline of a marking device for a moving object according to Embodiment 2 of the present invention. FIG. 5 is a block diagram showing an outline of the marking device for a moving object according to the second embodiment of the present invention.
In FIG. 1, 101 is an object to be marked, and 110 is a marking portion. 103 is a rail part, and is installed along the conveyance direction of a to-be-marked target object. Reference numeral 105 denotes a Y-direction moving unit. Reference numeral 107 denotes an X direction moving unit, and reference numeral 104 denotes a Z direction moving unit. The marking unit 110 includes a rail unit 103, an X direction moving unit 107, a Y direction moving unit 105, and a Z direction moving unit 104. 141 is a start point that is an upstream end of the specific section of the rail portion 103, and 142 is an end point that is a downstream end.

  Reference numeral 210 denotes another marking unit, which includes a rail unit 203, a Y-direction moving unit 205, an X-direction moving unit 207, and a Z-direction moving unit 204 that are installed along the conveyance direction of the object to be marked.

Reference numeral 241 denotes a start point that is an upstream end of the specific section of the rail portion 203, and reference numeral 242 denotes an end point that is a downstream end. In the present embodiment, there are two X-direction moving units 207, but there may be one or three or more.

  The function and configuration of each marking unit are the same as those in the first embodiment. By using two marking parts and each marking part complementing each other, the conveying speed of the object to be marked can be further increased and more marks can be applied.

Hereinafter, an example of a method of complementing each other will be described.
In order to give a mark without fading to the exact position of the object to be marked 101 during conveyance, the relative speed between the mark and the mark is small, and if possible, the speed difference is zero. It is desirable that Therefore, in order to minimize or eliminate the speed difference between the Z-direction moving unit 104 of the marking unit 110 and the object to be marked 101 being conveyed, the Z-direction moving unit 104 is used in the moving object marking device according to the present invention. Follows the movement of the object to be marked and applies the mark while moving by itself.

  Specifically, when the Y-direction moving unit 105 moves downstream from the position of the start point 141 and the X-direction moving unit 107 moves in the X direction on the Y-direction moving unit 105 to apply a mark. Marks are provided by moving the Z-direction moving unit 104 up and down. Therefore, the Y-direction moving unit 105 reaches the end point 142 while marking. Furthermore, in order to make a mark while following the movement of the object to be marked 101, the Y-direction moving unit 105 needs to return to the starting point 141.

  However, while the Y-direction moving unit 105 is returning from the end point 142 to the starting point 141, the place to be marked passes under the Y-direction moving unit 105. When the marking is performed while returning, the relative speed between the object to be marked and the Z-direction moving unit 104 increases, and the marking is blurred and high-quality marking cannot be performed.
