Description

  The present invention relates to a laser irradiation system equipped with a turntable on which a marking device is mounted and the marking device is rotated.

  High-function products use four semiconductor laser units and lenses, and there are known inking machines that irradiate a horizontal line by irradiating laser light over the entire 360 ° circumference. If it is installed at approximately the center of the space, the entire 360 ° work can be performed near the projection position using laser light.

  However, since it is a low-priced product that is widely used as a summing device, it is configured to irradiate laser light by using one semiconductor laser unit and one lens in the horizontal line, but the irradiation angle is 120. It is about °. Therefore, when 360 ° is required in the horizontal leveling operation, the operation is performed while rotating the ink discharger body. In this case, the operator has to reciprocate several times between the marking device and the vicinity of the position where the laser beam is irradiated.

  In addition, there are some inking devices that can rotate the head part manually and those that do not rotate, and those that do not rotate must be re-installed. It was cumbersome to have to. In this case, there is a horizontal line turntable that is used with a blackout device (see Patent Document 1). This horizontal line turntable is a switch that allows the upper table to be remotely operated wirelessly or by wire using the power of a motor or the like. And is rotated by starting and stopping the motor. By connecting the inking device to the horizontal line rotary table, the same operation as the high-function product 360 ° irradiation inking device can be performed.

  Next, there is an operation to accurately match the black (reference line) drawn on the floor or the like in the blacking device that irradiates the vertical line. In this case, high-function products can be accurately adjusted by providing a rotation fine adjustment mechanism on the ink discharger body, but popular products do not have a rotation fine adjustment mechanism, and the operator rotates the ink discharger body itself to create a line. The work was cumbersome because it was necessary to adjust to this. In this case, there is a vertical line fine-adjustment turntable that is used by mounting the inking device. By connecting to the inking device, the fine adjustment mechanism can be used to accurately match the reference line.

  In a turntable that is mounted and rotated by using an inking device as described above, as a means for connecting the inking device, first, a tripod-fixed female screw hole arranged at the bottom of the inking device is used for rotation. There is a type that connects a marking device by screwing a female screw hole into a male screw provided near the center of the top surface of the table. In addition, if there is a level adjustment leg on the ink-depositing device body, place it without connecting it.

  Level adjustment legs are usually provided at regular intervals (120 °) with three legs. Or, attach an adapter for height adjustment and fix it with screws. Alternatively, a concave hole is provided in accordance with the pitch of the level adjusting leg, and the leg is fixed in the hole.

  In the prior art, when connecting the inking device by screwing, it takes time to rotate and fix the inking device, which is a troublesome work. In addition, when using the inking device simply by placing it, the position of the inking device is not stable, so the inking device starts moving or falls when the rotating table is rotated or when it touches something from the outside. A problem occurs. Furthermore, when a concave hole is provided in accordance with the pitch of the leg for level adjustment, and the leg is inserted and fixed in the concave hole, only a dedicated ink discharger can be connected, and there is a problem that it cannot cope with a wide variety of leg pitches. is there.

  In order to achieve the above object, the present invention includes a semiconductor laser unit and a lens, which can irradiate vertical laser light and horizontal laser light, and has a lower leg with three legs, In a laser irradiation system including a turntable for rotationally driving the inking device, three radial concave grooves from the vicinity of the center of the upper surface of the upper rotating portion of the turntable toward the outer circumferential direction are provided at equal intervals (angle 120 °). The inking device is placed on the rotating table with the leg portion of the inking device engaged with the concave groove.

  According to the present invention, since the three radial concave grooves extending from the vicinity of the center of the upper surface of the upper rotating portion of the turntable on which the ink marking device is mounted toward the outer circumferential direction are provided at equal intervals (at an angle of 120 °), the ink marking device is provided. Can be mounted by engaging with the concave groove of the turntable, and the inking device can be easily installed on the turning table. In addition, the center of the inking device can be arranged at the center of the rotating table, and even an inking device having various leg sizes can be installed on the rotating table.
