This method has the advantage of being able to implement the same usage of existing equipment without power, but a differential gear must be applied between two casters in order for the equipment to drive in a curve or circle rather than straight, and power is transmitted from the gasoline engine. A chain or belt must be used to In addition, there are problems associated with loud noise, heat, and exhaust gas due to a gasoline engine.

Unlike the above-described type of painting device, a type of painting device in which a power source is mounted in the form of a trailer behind existing equipment is also used. In this painting device, a chair is installed for a user to sit on, and a gasoline engine is installed behind the chair to transmit power to the equipment. The advantage of this painting device is that the user can work while sitting instead of standing and walking, but the disadvantage of using a trailer type is that detailed work such as drawing a circle cannot be performed due to the volume of the skeleton that makes up the chair and its body. there is.

It can be formed with a thickness that can sufficiently support the weight to be applied.

The battery 112 serves to supply power to the motor 133 and the like.

Since a conventional lane painting apparatus equipped with an engine driven by gasoline, diesel, or the like requires a separate fuel reservoir, the weight of the entire lane painting apparatus inevitably increases.

However, the battery 112 according to an embodiment of the present disclosure is configured to charge and use electricity, and the volume of the battery itself is higher than that of a fuel storage tank containing fuel such as gasoline or diesel. It can be provided smaller than the reservoir, so the size or weight of the entire lane painting device can be greatly reduced compared to the conventional lane painting device. In addition, since the battery can be easily charged at home or outside without the need to go to a separate charging station to charge the battery, it is convenient to charge the battery more easily than conventional lane painting devices.

The control unit 120 controls driving and movement of the body unit 110, and may include a control box 121, a fixed handle 122, a steering handle 123, a motor output lever 124, and the like. .

Referring to FIG. 5, the control box 121 is a body including a power switch 121a, an emergency switch 121b, a voltmeter 121c, a fuse 121d, a direction change switch 121e, and the like.

The power switch 121a is configured to apply or cut off power to the main body 110, the control unit 120, the driving unit 130, the painting unit 140, the control unit 150, and the like, and the power switch 121a When power is cut off by , the lane painting device 100 may stop while decelerating due to friction with the ground. In addition, an emergency switch 121b may be provided to temporarily stop the lane painting device 100 in an unexpected situation that may occur during the painting process, and when the emergency switch 121b is operated, the motor driver The motor 133 or the like is controlled by 151 so that the output of the motor 133 becomes 0% at once, or the rotation of the rotational shaft 133a of the motor 133 is controlled by the reduction gear 133b to stop, The lane painting device 100 may be temporarily stopped.

In addition, the voltmeter 121c displays the current voltage of the battery 112, and the user can determine whether to charge or replace the battery based on the displayed voltage, and the fuse 121d is By blocking the current when a current greater than a prescribed value flows, it is possible to block the flow of overcurrent to the driving unit 130 .

4A is a diagram illustrating a first adjustment method of a motor output lever according to an embodiment of the present disclosure, and FIG. 4B is a diagram illustrating a second adjustment method of a motor output lever according to another embodiment of the present disclosure; 5 is a diagram illustrating a control unit of a lane painting device according to an embodiment of the present disclosure.

4A, 4B, and 5, the direction change switch 121e is configured to control the moving direction (ie, forward or backward) of the lane painting device 100, and in particular, the motor output lever 124 is When provided to control only the output of the motor 133 (second adjustment method), the direction change switch 121e can be operated together with the motor output lever 124. On the other hand, when the motor output lever 124 is operated in the first regulating manner, the moving direction (ie, forward or backward) of the lane painting device 100 and the output of the motor 133 by the motor output lever 124 Since this can be adjusted, the direction change switch 121e can be omitted.

The fixing handle 122 is a member coupled to the painting body 111 so as to move the painting body 111 forward or backward, or to adjust the moving direction.

The lane painting apparatus 100 according to an embodiment of the present disclosure may move forward or backward by being driven by the motor 133, or may move by being manually driven by a user's power. In this way, when the paint body 111 is manually driven, the user may push the fixing handle 122 provided on the paint body 111 to move the paint body 111 forward, and pull the fixing handle 122. As a result, the painted body 111 can be moved backward.

In addition, by pushing or pulling the fixing handle 122 in the left or right direction, the moving direction of the painted body 111 can be changed to the left or right direction. In particular, the fixing handle 122 is formed in a 'B' shape at one corner of the painting body 111, so that when the moving direction of the painting body 111 is switched to the left or right, the user is attached to the painting body 111. The applied force can be effectively transmitted to the fixing handle 122, so that the painted body 111 can be easily changed in the left and right directions.

The steering handle 123 is connected to the rotatable caster 132 and controls the rotation direction of the rotatable caster 132 to adjust the movement direction so that the movement direction of the main body 110 is switched to the left and right directions. .

The steering handle 123 according to an embodiment of the present disclosure is provided in a bar shape, and as the other end is coupled to the steering shaft 123a and the steering handle 123 rotates around the steering shaft 123a, the rotation The rotation direction of the typical caster 132 may also be switched to the left or right direction.

As an embodiment of the present disclosure, referring to FIG. 3A, the steering shaft 123a extends downward, and the lower end of the steering shaft 123a is formed in an inverted 'T' shape to be coupled to the caster support 122a. can In addition, as the rotational shaft 133a of the rotational caster 132 is coupled to the caster support 132a, when the steering handle 123 rotates clockwise or counterclockwise, the rotational axis of the rotational caster 132 ( The normal direction of 133a) can be switched to the left or right (ie, the rotation direction of the swivel type caster 132 can also be switched). In addition, since the bearing 132b is provided between the caster support 132a and the lower surface of the main body 110, the caster support 132a can rotate smoothly.

As another embodiment of the present disclosure, referring to FIG. 3B, the steering shaft 123a extends downward, and gears (reference numbers omitted) are provided at the lower end of the steering shaft 123a and the upper end of the caster support 132a, respectively. And, as the respective gears engage and rotate, rotation of the steering handle 123 can be transmitted to the caster support 132a. Accordingly, the rotational direction of the rotating shaft 133a of the rotational caster 132 may be switched to the left or right (ie, the rotational direction of the rotational caster 132 may also be switched).

In addition, in the task of painting a lane using the lane painting device 100 according to an embodiment of the present disclosure, the user controls the output of the motor 133 while adjusting the moving direction of the main body 110 However, there may be cases in which the spraying of paint must be performed simultaneously. The motor output lever 124 may be integrally coupled to the steering wheel 123 so that the user can simultaneously perform these various tasks.

That is, when the user is located at the rear of the lane painting device 100 and the steering handle 123 is formed to the user's left side, the motor output lever 124 is also formed to face the user's left side, and the motor output lever ( 124 is coupled to one side of the steering handle 123 or the steering shaft 123a, so that the motor output lever 124 can be rotated integrally with the steering handle 123.

Accordingly, the user can adjust the moving direction of the main body 110 (ie, steering wheel 123) and the output of the motor 133 (ie, adjust the motor output lever 124) with one hand. The paint may be sprayed with the other hand (ie, the paint spraying member 142 is controlled). In particular, the motor output lever 124 may have a shape so that the user can easily control the output of the motor 133 using a finger, and a detailed description thereof will be described later.

In addition, since the other side of the steering handle 123 according to an embodiment of the present disclosure is formed in a bent shape, the user can easily adjust the steering handle 123. That is, as the other side of the steering handle 123 is bent toward the user and the other end protrudes upward and is positioned adjacent to the user's side, the user can easily adjust the steering handle 123 during work. For example, when turning the body portion 110 right, as one end of the steering handle 123 rotates around the steering shaft 123a, it moves away from the user, and the user turns the body portion 110 right again. Alternatively, when attempting to turn left, steering wheel 123 may be inconvenient or difficult to adjust. However, as the distance between the user and the steering wheel 123 is reduced by forming the bent portion 123b in the steering wheel 123, the user can easily adjust the steering wheel 123.

In addition, the body portion 110 can be easily steered by not only controlling the steering handle 123 by applying force in the direction of rotation, but also pushing and pulling the bent portion 123b of the steering handle 123. That is, when the steering wheel 123 is formed in a straight shape, the user has no choice but to adjust the steering wheel 123 by applying force in the direction in which the steering wheel 123 rotates, but the steering wheel 123 has a bent portion 123b. ) is formed, the user applies a force to the bent part or the upwardly protruding part of the steering handle 123 in a straight direction (ie, the forward or backward direction of the main body 110) so that the user can move the steering wheel 123 can be easily adjusted.

The user can change the direction of the painted body 111 in the left and right directions using the fixed handle 122. In this way, the force of the workshop is not directly transmitted to the rotary caster 132, When the user applies force to the fixing handle 122 and the painting body 111 moves, the wheel of the rotary caster 132 coupled to the lower surface of the painting body 111 rotates and the direction of the painting body 111 this can be converted.

However, since the steering handle 123 according to an embodiment of the present disclosure is directly connected to the rotatable caster 132, when the steering handle 123 is rotated in left and right directions, the rotatable caster 132 also Since it can be rotated in right and left directions, the moving direction of the painted body 111 can be easily and immediately changed.

In particular, when the shape of the lane to be painted includes curves of various shapes, for example, curves with small curvature such as a ring shape, and the painting body 111 needs to be wandered at an abrupt angle, Rather than using the fixing handle 122, by using the steering handle 123 to directly change the direction of the rotary caster 132 in left and right directions, the lane can be painted more accurately.

The motor output lever 124 controls the output of the motor 133 so that the main body 110 is driven.

The motor output lever 124 according to an embodiment of the present disclosure is moved to one side or the other side, thereby controlling the direction in which the main body 110 moves forward or backward, and output increasing or decreasing the output of the motor 133. Control may be performed (hereinafter, referred to as a 'first adjustment method').

For example, referring to FIG. 4A , when the lever is in a neutral position, the motor 133 is stopped so that the lane painting device 100 may be maintained in a stopped state. In this case, since driving by the motor 133 is not executed, the user can manually move the painted body 111.

In addition, when the motor output lever 124 is moved to one side, the output of the motor 133 may be increased so that the painted body 111 moves in the forward direction, and when moved to the other side, the painted body 111 The output of the motor 133 may be increased so that is moved in the backward direction.

In this way, the motor output lever 124 may be provided to control both the output control of the motor 133 and the direction change control through the direction change of the lever.

In addition, as another embodiment of the present disclosure, referring to FIG. 4B , when the motor output lever 124 is located on one side and the output of the motor 133 is 0%, the motor 133 is in a stopped state, and the lane is painted. The device 100 is also in a stopped state. In addition, as the motor output lever 124 is moved to the other side, the output of the motor 133 increases so that the lane painting device 100 can be moved, and the motor output lever 124 is completely positioned on the other side so that the motor 133 When the output of ) becomes 100%, the motor 133 may be driven with maximum output (hereinafter, referred to as 'second control method').

When the motor output lever 124 is formed in the above-described manner, only the output amount of the motor 133 can be controlled according to the change in position of the motor output lever 124, so that the lane painting device 100 moves forward or In order to reverse, a direction change switch 121e for changing the rotation direction of the motor 133 may be provided separately.

For example, in the lane painting device 100 in a stopped state, after setting the direction change switch 121e to the forward position so that the moving direction of the painting body 111 is forward of the main body 110, the motor By moving the output lever 124 to the other position, the motor 133 is driven according to the output of the motor 133 corresponding to the position moved to the other side, so that the lane painting device 100 may move forward.

In order to move the lane painting device 100 backward during forward driving, the driving of the motor 133 is stopped and the direction of rotation is changed so that the lane painting device 100 moves backward. That is, the motor output lever 124 is moved to one side to set the output of the motor 133 to 0% to stop the painted body 111, and after the motor 133 is stopped, the direction change switch 121e is turned on. By setting it to the reverse position and moving the motor output in the other direction to drive the motor 133 again, the lane painting device 100 may move backward.

The above-described method ("second adjustment method") is a method of controlling the output control of the motor 133 and the direction change control using different components.

That is, the motor output lever 124 according to the second control method is provided so that only the output of the motor 133 can be adjusted within a range in which the position of the lever can be adjusted, and the motor output lever 124 according to the first control method ) is provided not only to adjust the output of the motor 133 within an adjustable range of the position of the lever, but also to adjust the forward or backward drive of the painted body 111, that is, the moving direction.

A conversion process may be required to adjust the output in the first regulation manner. For example, the second control method is a method in which the voltage of the variable resistor is changed from 0V to 5V while changing the resistance value of the variable resistor, and this is proportional to the output amount of the motor 133 . Unlike this, in the first control method, when the motor output lever 124 is located in the neutral position, the voltage of the variable resistor in the second control method means 2.5V. Therefore, conversion of voltage as shown in Table 1 below may be required.

existing change 2.5V to 5V 0V to 5V 0V to 2.5V 5V to 0V

From the neutral position to the forward 100% position, the conventional variable resistor can be increased from 2.5V to 5V, which can be converted from 0V to 5V to change the forward output from 0% to 100%. In addition, the existing variable resistor can be reduced from 2.5V to 0V from the neutral position to the reverse 100% position, and to convert it from 0% to 100% of the reverse output, it must be converted to 0V at 2.5V and 5V at 0V. can

A microcontroller may be provided in the control unit 150 to implement this conversion.

The simple conversion process is as follows. When the 0V to 5V voltage value of the variable resistor is input to the microcontroller, it is programmed to convert as shown in Table 1, so that 0V to 5V is output for a voltage value of 2.5V to 5V, and 5V to 0V is output for a voltage value of 0V to 2.5V. It also outputs a signal that the direction is reverse (reverse).

In addition, the first control method may be implemented by having a gear ratio of a gear coupled to the motor output lever 124 different from that of the second control method and coupling a variable resistance. According to the conversion of the motor output lever 124, signals related to the motor output of the set size and the moving direction of the painted body 111 are transmitted to the motor driver 151 of the control unit 150, so that the output of the motor 133 can be regulated.

In addition, the motor output lever 124 according to an embodiment of the present disclosure may have a distal end formed in a semi-cylindrical shape or a ring shape so that the user can easily control the output of the motor 133 using one hand. can

For example, referring to FIGS. 4A and 4B , when the distal end of the motor output lever 124 is formed in a semi-cylindrical shape, the user inserts or inserts the finger of one hand into the distal end of the motor output lever 124. By gripping the motor output lever 124, the output of the motor 133 can be adjusted by pushing the motor output lever 124 forward or pulling it towards the user with a finger.

When the motor output lever 124 is formed in the first adjustment method described above, the user pushes the motor output lever 124 forward with a finger to increase the output of the motor 133 and move the lane painting device 100 forward. The output of the motor 133 may be increased in a direction in which the lane painting device 100 moves backward while pulling toward the user. In addition, when the motor output lever 124 is formed in the above-described second control method, the user can increase or decrease the output of the motor 133 while pushing the motor output lever 124 forward or pulling it toward the user. can

In this way, the user controls the motor output lever 124 with some fingers and grips the steering wheel 123 with other fingers to adjust the steering wheel 123, thereby controlling the movement of the lane painting device 100 and the motor 133. ) can be controlled at the same time.

In addition, the motor output lever 124 according to an embodiment of the present disclosure may be coupled to the steering wheel 123 or the steering shaft 123a, so that when the steering wheel 123 rotates, the motor output lever ( 124) is also rotated integrally, the distance between the steering wheel 123 and the motor output lever 124 can be maintained, and even if the steering wheel 123 is rotated, the user can operate the steering wheel 123 and the motor with one hand. Difficulty, such as a user feeling uncomfortable, does not occur in controlling the output lever 124 at the same time.

In addition, in order to stably support the painted body 111, a plurality of fixed casters 131 may be coupled in symmetrical positions.

The rotary caster 132 is coupled to the lower surface of the painted body 111, and 360 degrees on a horizontal surface based on the lower surface of the painted body 111 so that the painted body 111 can be rotated in the left and right directions. can rotate

Referring to FIG. 6A, as a conventional painting device, a trailer for adjusting the moving direction is coupled to a body in which paint is accommodated, and as the trailer rotates in left and right directions based on a connecting shaft between the body and the trailer, the painting path may be changed

Referring to FIG. 6A, in the conventional painting apparatus, a main body and a trailer are separately configured and connected, and the range in which the trailer can rotate is limited so that the main body changes direction in left and right directions. Accordingly, the shape of characters to be painted while the main body changes direction at a sharp angle is a very difficult task using a conventional painting device.

However, referring to FIG. 6B , it can be seen that the road can be painted in various ways depending on the rotation angle of the rotatable caster 132 according to an embodiment of the present disclosure.

That is, in the lane painting apparatus 100 according to an embodiment of the present disclosure, the rotatable caster 132 capable of rotating 360 degrees is coupled to the painting body 111 itself, so that the rotatable caster 132 is configured by a different configuration. Since it can be rotated without restriction, painting work can be performed in various ways.

Referring to FIG. 6B , the lane painting device 100 can paint the road while moving along a gently curved path with a large turning radius, and can paint not only ring-shaped circular characters but also dot-shaped circular characters. You can check.

In addition, in the lane painting apparatus 100 according to an embodiment of the present disclosure, the rotary caster 132 and the motor 133 are coupled to the same rotational shaft 133a, so that the lane painting apparatus 100 travels along a curved path. When a painting operation is performed along , since the center of rotation of a curved path may be located on a virtual extension line extending from the rotation axis 133a, the painting body 111 may be moved along an accurate curved path. The motor 133 generates power and transmits power to the rotary caster 132, and the painted body 111 can be driven by the motor 133.

The motor 133 according to an embodiment of the present disclosure is coupled to the rotary caster 132 and the integral rotary shaft 133a, so that the power generated by the motor 133 is efficiently transmitted to the rotary caster 132. can In addition, a reducer 133b capable of reducing the speed of the motor 133 may be coupled to the motor 133, which will be described in detail later.

The motor 133 according to an embodiment of the present disclosure may be provided as a BLDC motor. In the case of painting equipment equipped with a gasoline engine, additional configurations such as a gasoline reservoir, a differential gear, and a belt for power transmission are required, and noise, exhaust gas, and high-temperature heat may be emitted from the gasoline engine during the work process. , there are many disadvantages of difficulties in the working process.

However, compared to general motors, the BLDC motor has a smaller size, can reduce the overall weight of the lane painting device 100, and does not significantly increase its noise even when used for a long time. In addition, when the rotary caster 132 rotates, difficulties such as not immediately changing the direction of the rotary caster 132 due to the motor 133 coupled to the rotary caster 132 may occur. However, since the motor 133 is provided as a BLDC motor, occurrence of such a problem can be minimized. In addition, due to the characteristics of the painting work, the noise caused by the painting work may be greatly generated, but compared to the conventional painting device using an engine, in the case of the lane painting device 100 using a BLDC motor, the noise generated during the work is greatly reduced can make it

The painting unit 140 sprays paint to paint the road, and may include a paint dissolving tank 141, a paint spraying member 142, a reflector spraying member 143, and the like.

The paint dissolution tank 141 according to an embodiment of the present disclosure stores paint for painting a road.

Heatable paint that is sprayed in liquid form and solidified at room temperature is mainly used as the paint, and in order to remain dissolved, the paint must be preserved at a temperature of about 180 to 200 degrees, and heat is supplied from the gas supply member 141a. By receiving, the paint can be stored while maintaining a temperature state of about 180 to 200 degrees, which is an appropriate storage temperature, in the paint dissolution tank 141.

The paint spreading member 142 paints the road by spraying paint, and paints such as white and yellow may be used.

The paint spreading member 142 according to an embodiment of the present disclosure may protrude from the side surface of the paint body 111, and a spreading guide 142a is formed so that the paint can be sprayed at an accurate position on the road, A spray control rod 142b capable of controlling spraying of the paint may be provided.

In detail, it is difficult to easily grasp that the paint is sprayed at the location of the user using the lane painting device 100, and it is checked whether the path to be painted and the position of the lane to be painted match while the lane painting device 100 moves. There is something difficult to do. In order to overcome this point, the spraying guide 142a guiding the position or the path where the paint is to be sprayed on the road is provided so as to face the front of the paint spreading member 142, so that the user can control the position of the spraying guide 142a. While checking, the paint can be accurately sprayed on the position of the lane to be painted.

In addition, the spray control rod 142b may be coupled to the paint spraying member 142 so as to control the outflow of the paint from the paint spreading member 142 . The spray control rod 142b is formed to extend from the paint spreading member 142 to a position close to the user, so that the user can easily manipulate the spray control rod 142b with the other hand during painting. At the same time, as described above, the user can control the steering wheel 123 and the motor output lever 124 with one hand.

The reflector spraying member 143 injects the reflector at the location where the paint is sprayed, that is, the painted location, and can spray the reflector stored in the reflector reservoir 143a onto the lane of the road.

The reflector spraying member 143 according to an embodiment of the present disclosure may spray a reflector formed of glass beads or the like onto the painted lanes. In general, after painting the lane, before the paint dries, a reflector may be sprayed, and by spraying the reflector, the visibility of the lane at night or in rainy weather may be improved, which may occur due to the lane not being recognized. Traffic accidents can be prevented.

The control unit 150 controls the adjusting unit 120, the driving unit 130, the painting unit 140, and the like, and may include a motor driver 151 and the like.

Referring to FIGS. 7 and 8 , the motor driver 151 according to an embodiment of the present disclosure may adjust the output generated by the motor 133 by controlling the motor 133, and the painted body 111 may You can control the movement speed, etc.

In an environment in which a user paints a lane using a conventional painting device by hand, the user applies force on an uphill road or pulls the painting device on a downhill road to prevent the speed of the painting device from decreasing or increasing. I had no choice but to control it.

In addition, even if the motor 133 according to an embodiment of the present disclosure constantly generates a specific output, the painted body 111 moves on an uphill road due to the weight of the body part 110 and the painting part 140. The speed may be slow, and on the contrary, the moving speed of the painted body 111 inevitably increases on a downhill road.

When working in such a working environment, the motor driver 151 may control the motor 133 by receiving output information of the motor 133 from the motor output lever 124 .

In addition, the speed setting unit (not shown) sets the speed at which the painted body 111 moves, and the speed can be set through the motor driver 151. By connecting, the painting body 111 can be set to move while maintaining a constant speed regardless of the working environment.

For example, when working on a downhill road, the motor 133 may be controlled to prevent the lane painting device 100 from speeding up or slipping.

That is, when the user sets the output of the motor output lever 124 to 0% on a downhill road, it can be checked whether the speed of the wheels of the fixed caster 131 and the rotary caster 132 also becomes 0 m/s. When the speed of the wheel is not 0 m/s, the output of the motor 133 set in the motor output lever 124 may be continuously checked and controlled so that the speed of the wheel becomes 0 m/s.

In addition, the motor driver 151 according to an embodiment of the present disclosure may control the speed at which the painted body 111 moves.

For example, on an uphill road or a downhill road, the speed of the painting body 111 may be slowed down or increased due to the slope of the road, and the moving speed is about approx. When it is set to 3 to 5 km/h, speed control by the motor driver 151 may be implemented so that the lane painting device 100 can work while maintaining the preset speed.

As described above, the moving speed of the painted body 111 is continuously checked, and even though the user does not change the moving speed of the painted body 111, the moving speed of the painted body 111 is higher than the set moving speed. When a slowdown or speedy situation occurs, the output of the motor 133 is increased by the motor driver 151, so that the moving speed of the painted body 111 can be increased. In addition, the output of the motor 133 is reduced by the motor driver 151 or the rotation speed itself is reduced by controlling the reduction gear 133b, so that the current moving speed can be controlled to return to the preset moving speed.

In addition, the motor driver 151 according to an embodiment of the present disclosure controls the painting body 111 to automatically move along the guide line by recognizing the guide line displayed on the road for painting with a sensor. can do. That is, even if the user does not control the painting body 111, the painting body 111 autonomously travels along the guide line and automatically paints the lanes.

In addition, the motor driver 151 according to an embodiment of the present disclosure may avoid obstacles recognized during the painting process through an obstacle detection sensor (not shown) provided in the front portion of the painting body 111 .

That is, even if the user does not recognize the obstacle or does not make a decision to avoid the obstacle during the painting process, the motor driver 151 immediately outputs the output of the motor 133 when the obstacle is recognized by the obstacle detection sensor. By controlling the speed value of the painted body 111 to 0 by controlling to 0%, the painted body 111 can be stopped.

In the above description, various embodiments of the present disclosure have been presented and described, but the present disclosure is not necessarily limited thereto. It will be readily apparent that branch substitutions, modifications and alterations are possible.
