Description

Description: TECHNICAL FIELD The present invention relates to a level marking machine capable of easily performing horizontal marking, which is a standard for finishing and other works when constructing a building.

[Prior Art] Conventionally, when building a building, the horizontal marking for finishing and other works is set at an appropriate position for measuring the leveling instrument, and the level is measured for the marking object. I was marking up.

This type of measurement is performed by a set of a person who normally operates the leveling instrument and a person who measures the level of the object. That is, it is necessary to have a person who uses a marking tool to mark a measurement point using a jig for measuring at a level measurement position, and a person who operates a leveling instrument. In addition, when connecting the measurement points to perform continuous horizontal marking, one person holds the sumibo of the marking tool at one measuring point and another person touches the tip of the marking thread at the other measuring point. I was holding the tentacles and inking them with ink thread impregnated with ink.

[Problems to be Solved by the Invention] In the above-described conventional horizontal marking, a person who operates a leveling instrument and a person who marks a measuring point with a marking tool must be performed by a group of two persons. I have to. However, it is uneconomical for two people to carry out marking work because it is difficult to secure a specialized worker these days. In addition, if the leveling, which is the horizontal reference for other work, is delayed, the subsequent work cannot be performed, the process is disturbed, and the construction work cannot proceed smoothly.

In view of this, the present invention enables one person to easily perform horizontal marking out at a predetermined height by receiving light from a laser emitting device that represents a reference height, and further, the accuracy of horizontal marking out is improved to improve the quality of construction work. The purpose is to improve management.

[Means for Solving the Problem] The present invention is a level marking machine that achieves the above object,
A main frame is erected on the trolley, a slide frame is provided on the upper part of the slide frame so as to be able to move up and down, and a horizontal frame is provided on the upper part of the slide frame, and a black ink jet nozzle is movably provided on it. The height of the slide frame can be adjusted by the height adjustment device, which allows the laser receiver mounted on the slide frame to receive the laser from the reference laser emitter, and the control panel to operate the height adjustment device accordingly. ing. Further, the black ink jet nozzle is adapted to be moved along the horizontal frame by the moving device, and the black ink jet nozzle is communicated with the black ink supply device.

In order to level the horizontal frame, a leveling device is provided and an inclinometer is attached to the horizontal frame.
The leveling device can be operated by the control board based on the measurement signal.

[Operation] When using the level marking machine described above to mark a horizontal reference line of a certain height on the object under construction, move the carriage to the object position and move the horizontal frame to the object. The nozzles are arranged in parallel and the ejection nozzle is adjacent to the object (state of FIG. 3). In order to match the injection nozzle with the predetermined height, the laser receiver receives the laser of the reference height from the laser emitter, and based on the received light, the control panel calculates the height adjustment amount and operates the height adjustment device. By raising and lowering the slide frame, the jet nozzle is made to match the predetermined height. When the horizontal frame needs to be adjusted horizontally, the control board adjusts the leveling device based on the measured value of the tilt measuring device.

Next, while supplying black ink from the black ink supply device to the black ink jet nozzle,
When the black ink jet nozzle is moved by the moving device, the black ink jet nozzle moves to the target object while moving along the horizontal frame. When the marking of this position is completed, the carriage can be moved to the next marking section, and one worker can perform horizontal marking one after another.
