Abstract

PURPOSE:To perform a marking operation with a high accuracy by one person by receiving laser light at a reference height, setting an ink injection nozzle at a prescribed height and adjusting the levelnessity of a horizontal frame by an inclination measuring device. CONSTITUTION:When an object to be marked under building is marked with a reference line at a prescribed height, a carriage 1 is moved to the position of the object to be marked and an ink injection nozzle 5 is opposed to the object. Laser light at a reference height is received by a laser sensitive device 9, a slide frame is elevated or lowered by operating a height regulator 6 and a horizontal frame 4 is set at a prescribed height. Then, the levelness of the horizontal frame 4 is adjusted by operating a levelnessity adjusting device 11 based on the measured value of an inclination measuring device 12. Thereafter, an ink is supplied to the nozzle 5, which is moved in a horizontal direction and a marking is performed. Thus, an operation conventionally performed by two persons can be performed by one person with a high accuracy.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a level marking machine that facilitates horizontal marking that serves as a reference for finishing and other construction work when constructing a building.

[Prior Art] Conventionally, when constructing a building, horizontal markings for finishing and other construction work were done by setting a leveling instrument at an appropriate measuring position and measuring the level of the object to be marked. He was inking.

This type of measurement is usually carried out by a pair of people, one operating the leveling device and the other person measuring the level of the object. That is, there is a need for a person to mark measurement points using a measuring jig at the position where the level is to be measured using a marking tool, and a person to operate the leveling device. Also, when connecting measurement points to draw continuous horizontal ink lines, one person should hold the ink pot (the ink tool) at one measurement point, and the other person should be at the tip of the ink thread at the other measurement point. He was holding a karashi and inking it with ink thread impregnated with ink.

[Issue i1 to be solved by the invention] In the conventional horizontal marking, two people work together: a person who operates a leveling device and a person who marks measurement points using a marking tool. There must be. However, these days it is difficult to secure specialized workers, so it is uneconomical for two people to do the marking work. Furthermore, if the leveling, which serves as a horizontal reference for other work, is delayed, subsequent work cannot be carried out, disrupting the process and preventing the construction from proceeding smoothly.

Therefore, the present invention makes it possible for one person to easily mark the horizontal markings at a predetermined height by receiving light from a laser emitter that indicates the reference height, and improves the precision of the horizontal markings to improve the quality of construction work. The aim is to improve management.

[A Thousand Steps to Solve the Problems] The present invention is a level marking machine that achieves the above object, in which a main frame is erected on a cart, a slide frame is provided on the upper part of the main frame so as to be movable up and down, and the upper part of the slide frame is A horizontal frame is provided on which a black ink jet nozzle is movably mounted. The height of the slide frame can be adjusted by a height adjustment device, which means that a laser receiver attached to the slide frame receives the laser from a reference laser emitter, and the control panel operates the height adjustment device based on the laser beam received from the reference laser emitter. ing. In addition, the ink jet nozzle is moved by a moving device.
The black jet nozzle is adapted to be moved along a horizontal frame, and the black jet nozzle is communicated with a black supply device.

In order to level the horizontal frame, a leveling device is provided and an inclination measuring device is attached to the horizontal frame, so that the leveling device can be operated by a control panel based on the measured value.

[Operation] When using the above level marking machine to mark a horizontal reference line at a certain height on an object under construction, move the trolley to the object and place the horizontal frame on the object. Arrange in parallel, with the injection nozzle adjacent to the object (state shown in Figure 3)
. In order to match the injection nozzle to a predetermined height, the laser receiver receives the laser at 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. , the injection nozzle is brought to a predetermined height by raising and lowering the slide frame. If the horizontal frame needs to be leveled, the control panel adjusts the leveling device based on the measurements of the inclination measuring device.

Next, if the ink jet nozzle is moved by the moving device while supplying ink from the ink supply device to the ink jet nozzle, the black jet nozzle inks the object while moving along the horizontal frame. Once marking at this position is completed, the cart is moved to the next marking location, and one worker can perform horizontal marking one after another.

[Example] Embodiments of the present invention will be described with reference to FIGS. 1 to 3.

A trolley l for making the level marking machine movable is composed of a horizontal portion 1a, a vertical portion 1b on its periphery, and casters 1c on the bottom, and a main frame 2 is erected on top of this trolley l. . A slide frame 3 is provided on the upper part of the main frame 2 so as to be movable up and down.
A horizontal frame 4 is horizontally attached to the upper part of the slide frame 3, and a black ink jet nozzle 5 is moved along this slide frame 3. Also, abutment rods 4a are attached to both ends of the surface of the horizontal frame 4 facing the object to be marked, and when marking the object, both abutment rods 4a are brought into contact with the object, and the horizontal frame 4 is made parallel to the object.

The height of the slide frame 3 is adjusted relative to the main frame 2 by a height adjustment device 6, which is controlled by a servo motor 6a attached to the main frame 2, a bracket 7 attached to the slide frame 3, and a servo motor. It is constituted by a screw shaft 6b provided between a motor 6a and a screw shaft 6b. The slide frame 3 is raised and lowered by the rotation of the servo motor 6a. The servo motor 6a is actuated by a control panel 8 installed on the trolley l, and a laser receiver 9 attached to the top of the slide frame 3 controls the light emission of a laser emitter IO that emits a laser beam at a reference height. Laser light is received from the opening 10a, and the control panel 8 calculates the amount of height adjustment based on the received light and operates the servo motor 6a. Note that the laser emitter IO and the laser receiver 9 are both rotated, and when the laser receiver 9 receives the laser beam, it sends a light reception signal to the control panel 8.

The horizontal frame 4 is then made horizontal.

The black jet nozzle 5 is held on the horizontal frame 4 via a cursor l3, and the cursor 13 is moved along the horizontal frame 4 by a moving device l4. This moving device l4 is constructed by attaching a drum 14b to the rotating shaft of a moving motor 14a attached to one end of a horizontal frame, and passing a belt 14c wound around the drum 14b around a pulley l4d at the other end of the horizontal frame 4 via a cursor l3. Then, the injection nozzle 5 is moved horizontally via the cursor 3 by the rotation of the moving motor 14a. The rotation of the moving motor 14a is stopped by an operation switch 15 provided at the bottom of the main frame, and the control panel 8 is used to move the cursor 13 by a predetermined amount and then stop or return it. Further, the ink jet nozzle 5 is communicated with a black ink supply device 19 provided on the trolley 1 via a hose 18, so that ink is supplied to the ink jet nozzle 5 when inking.
