Description

Electric fusion type lane painting device {MOTORIZED FUSION TYPE LANE PAINGTING APPARATUS}

The present disclosure relates to a motor in which a fixed caster and a rotating caster are coupled to a painting body, and a battery is connected to the rotating caster in order to reduce the physical burden of the worker and paint various types of lanes in the work of painting the lanes of the road It relates to an electric fusion-bonded lane painting apparatus in which a painting body is driven by a motor by combining the .

As is well known, various types of painting devices may be used to perform the task of painting the lanes of the road.

For example, the conventional manual fusion-bonding paint machine is moved by the power of the worker, and the worker has to bear the paint machine of about 240 kg due to the nature of the work in which the material is put into the heavy weight (about 120 kg) of the paint machine (up to 120 kg). Due to the weight of these paints and paints, work on flat ground makes the worker get tired quickly, and it is impossible for one worker to work on a slope, so two or more people are needed as an assistant, so there is a difficulty in requiring a large number of manpower.

In addition, the conventional painting apparatus is generally equipped with an engine fueled by gasoline or diesel, and is made to transmit the power of the engine by connecting two wheels in front of the painting apparatus to the engine. Although this method has the advantage of being able to implement the same usage of existing equipment without power, a differential gear must be applied between the two casters in order for the equipment to travel in a curve or circle instead of in a straight line, and the power is transmitted from the gasoline engine. You must use a chain or belt for this. In addition, there is a problem accompanied by loud noise, heat, and exhaust gas caused by a gasoline engine.

Unlike the above-described type of painting apparatus, a type of painting apparatus equipped with a power source in the form of a trailer behind existing equipment is also used. Such a painting device can transmit power to the equipment by installing a chair so that the operator can sit and installing a gasoline engine behind the chair. The advantage of such a painting device is that the worker can work in a seated state rather than standing and walking, but there is a disadvantage that detailed work such as drawing a circle cannot be performed due to the volume of the chair and the skeleton forming the body while using the trailer type. have.

This is a flowchart explaining

1 to 6B , the electric fusion-bonded lane painting apparatus 100 according to an embodiment of the present disclosure includes a body part 110 , a control part 120 , a driving part 130 , a painting part 140 , It may include a control unit 150 and the like.

The main body 110 is a body of the electric fusion splicing type lane painting apparatus 100 , and may include a painting body 111 , a battery 112 , and the like.

The painted body 111 is a body of the main body 110 , and can support the adjusting unit 120 , the driving unit 130 , the painting unit 140 , the control unit 150 , and the like, and a fixed caster 131 on the lower surface. ), the rotatable caster 132, etc. may be coupled.

According to an embodiment of the present disclosure, the painting body 111 may be formed in the shape of a square plate, and in general, about 120 kg of paint can be loaded in the lane painting apparatus, and the loaded paint and other components are included. It can be formed to a thickness that can sufficiently support the weight.

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

A conventional lane painting apparatus equipped with an engine driven by gasoline, diesel, etc. as a fuel requires a separate fuel storage tank, which inevitably increases the weight of the entire lane painting apparatus.

However, the battery 112 according to an embodiment of the present disclosure is used by charging electricity, and the volume of the battery according to the usable time is smaller than that of fuel storage such as gasoline and diesel, compared to fuel such as gasoline and diesel, Due to this, the overall size or weight of the lane painting apparatus can be significantly reduced compared to the conventional apparatus. In addition, since it is possible to easily charge the battery at home or outside without having to go to a separate charging station to charge the battery, the battery can be easily charged compared to the existing lane painting device, which is excellent in convenience.

The control unit 120 controls the driving of the main body 110 , and includes a fixed handle 121 , a steering handle 122 , a motor output lever 123 , a direction change switch 124 , a voltmeter 125 , and the like. may include

The fixed handle 121 is a member coupled to the painted body 111 to move the painted body 111 forward or backward, or to adjust the moving direction.

The lane painting apparatus 100 according to an exemplary embodiment of the present disclosure may be moved forward or backward by being driven by the motor 133 , and alternatively, may be moved by the force of an operator, that is, manually driven. In this way, when the painting body 111 is manually driven, the operator can advance the painting body 111 by pushing the fixing handle 121 provided in the painting body 111, and pulling the fixing handle 121 Accordingly, the painted body 111 can be moved backward.

In addition, when the operator pushes or pulls the fixing handle 121 in the left and right directions, the moving direction of the painted body 111 may be switched to the left and right directions. In particular, the fixed handle 121 is formed in a 'L' shape at one corner of the painted body 111, so that when the moving direction of the painted body 111 is switched to the left and right, the operator can The force of the operator may be effectively transmitted to the painting body 111 so that the painted body 111 can be easily changed in the left and right directions by the applied force.

The steering handle 122 is a member coupled to the painted body 111 to adjust the moving direction so that the painted body 111 is switched to the left and right directions.

The operator can change the direction of the painted body 111 in the left and right directions by using the fixed handle 121. In this way, the force of the workplace is not directly transmitted to the rotary caster 132, but As the worker applies force to the fixed handle 121 and the painted body 111 moves, the wheel of the rotary caster 132 coupled to the lower surface of the painted body 111 rotates to rotate the painted body 111 in the direction of the painted body 111 . This can be switched.

However, since the steering handle 122 according to an embodiment of the present disclosure is directly connected to the rotary caster 132, when the steering handle 122 is rotated in the left and right directions, the rotary caster 132 is also Since it can be rotated right and left, it is possible to easily and immediately change the moving direction of the painted body 111 .

In particular, when the shape of the lane to be painted includes curves of various shapes, for example, a curve with a small curvature such as a ring shape is included. Rather than using the fixed handle 121 , the lane can be painted more accurately by directly changing the direction of the rotary caster 132 to the left and right using the steering handle 122 .

The motor output lever 123 controls the output of the motor 133 .

By moving the motor output lever 123 according to an embodiment of the present disclosure to one side or the other side, the output of the motor 133 may be adjusted.

For example, referring to FIG. 3A , when the motor output lever 123 is positioned on one side and the output of the motor 133 is 0%, the motor 133 is in a stopped state, and the lane painting apparatus 100 is also stopped. become in a state of being In addition, as the motor output lever 123 is moved to the other side, the output of the motor 133 increases, so that the lane painting apparatus 100 may be moved, and the motor output lever 123 is completely positioned on the other side to the motor 133 . ) when the output becomes 100%, the motor 133 may be driven to the maximum output.

When the motor output lever 123 is formed in the manner described above, only the output amount of the motor 133 may be controlled according to a change in the position of the motor output lever 123 , so that the lane painting apparatus 100 is moved forward or In order to move backward, a direction change switch 124 for changing the rotation direction of the motor 133 may be separately provided.

For example, in the lane painting apparatus 100 in a stationary state, the direction change switch 124 is set to the forward position so that the moving direction of the painting body 111 is set to be in front of the main body 110 , and then the motor By moving the output lever 123 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 apparatus 100 may be moved forward.

In order to move the lane painting apparatus 100 backward during forward driving, the lane painting apparatus 100 may be moved backward by stopping the driving of the motor 133 and changing the rotation direction. That is, the motor output lever 123 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 changeover switch 124 is turned on. By setting the reverse position and moving the motor output in the other direction to re-drive the motor 133 , the lane painting apparatus 100 may be reversed.

The above-described method (hereinafter, referred to as a 'first output control method') is a method of controlling the output control of the motor 133 and the direction change control with different configurations.

In addition, the motor output lever 123 according to another embodiment of the present disclosure (hereinafter referred to as a 'second output control method') performs both the output control of the motor 133 and the direction change control through the direction change of the lever. It can be formed to be controllable.

For example, referring to FIG. 3B , when the lever is in the neutral position, the motor 133 may be stopped and the lane painting apparatus 100 may be maintained in a stopped state. In this case, since driving by the motor 133 is not executed, the operator may manually move the painting body 111 .

In addition, when the motor output lever 123 is moved to the other side, the output of the motor 133 may be increased so that the painted body 111 moves in the forward direction. The output of the motor 133 may be increased to move in the backward direction.

That is, the motor output lever 123 according to the first output control method is provided so that only the output of the motor 133 can be adjusted within the range in which the position of the lever can be adjusted, and the motor output lever according to the second output control method Reference numeral 123 is provided to adjust the output of the motor 133 within a range in which the position of the lever can be adjusted, as well as to adjust the forward or backward driving, that is, the moving direction of the painted body 111 . do.

A set of conversion processes may be required to adjust the output in the second output adjusting method. For example, the first output 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 . Alternatively, in the second output control method, when the motor output lever 123 is positioned at a neutral position, the voltage of the variable resistor in the first output control method is 2.5V. Therefore, it may be necessary to convert the voltage as shown in Table 1 below.

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 existing variable resistor can be increased from 2.5V to 5V, and it can be converted from 0V to 5V to change the forward output from 0% to 100%. Also, from the neutral position to the reverse 100% position, the existing variable resistor can be reduced from 2.5V to 0V. can

In order to implement such a conversion, a microcontroller may be provided in the control unit 150 .

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 The signal is output and the direction is reversed (reverse) as well.

In addition, by providing a gear ratio of the gear coupled to the motor output lever 123 to be different from that of the first output adjusting method and coupling the variable resistor, the second output adjusting method may be implemented. According to the conversion of the motor output lever 123, a signal related to the motor output of a set size, the moving direction of the painted body 111, etc. is transmitted to the motor driver 151 of the control unit 150, so that the output of the motor 133 is can be adjusted.

The voltmeter 125 displays the current voltage of the battery 112 , and the operator can determine whether to charge the battery or whether to replace it based on the displayed voltage.

In addition, an emergency switch 124a may be provided to temporarily stop the lane painting apparatus 100 in an unexpected situation that may occur during the painting operation. When the emergency switch 124a is operated, the output of the motor 133 is controlled to be 0% at one time by the motor driver 151, or the rotation shaft 133a of the motor 133 is controlled by the speed reducer 133b. By controlling the rotation to be stopped, it is possible to stop the lane painting apparatus 100 in an unexpected situation.

The driving unit 130 drives the painted body 111 , and may include a fixed caster 131 , a rotary caster 132 , a motor 133 , and the like.

The fixed caster 131 is coupled to the lower surface of the painted body 111, and is fixedly coupled so as not to rotate on a horizontal plane with respect to the lower surface, so that the painted body 111 moves forward or backward. 131) can be rotated. In addition, a plurality of fixed casters 131 may be coupled at symmetrical positions to stably support the painted body 111 .

The rotatable caster 132 is coupled to the lower surface of the painted body 111, and 360 degrees on a horizontal plane with respect to 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. 4A , as a conventional painting device, a trailer for controlling a movement direction is coupled to a body in which the paint is accommodated, and as the trailer rotates in the left and right directions based on the connection shaft between the body and the trailer, the painting path may be changed

In the conventional painting apparatus, the main body and the trailer are separately configured and connected, and the range in which the trailer can rotate is limited so that the main body is changed in the left and right directions. Accordingly, the shape of a character to be painted while the body changes direction at an abrupt angle is a very difficult task by a conventional painting apparatus.

However, referring to FIG. 4B , it can be seen that the road can be painted in various paths depending on the angle at which the rotatable caster 132 is rotated according to an embodiment of the present disclosure.

That is, in the lane painting apparatus 100 according to an embodiment of the present disclosure, a 360-degree rotatable rotatable caster 132 is coupled to the painting body 111 itself, so that the rotatable caster 132 is formed by a different configuration. Since it can be rotated without limitation, the painting operation can be performed in various paths.

Referring to FIG. 4B , it can be seen that the lane painting apparatus 100 can paint a road while moving along a gentle curved path with a large turning radius, and can paint not only ring-shaped circle characters but also point-shaped circle characters. can be checked

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

The motor 133 according to an embodiment of the present disclosure is coupled to the rotary shaft 133a integral with the rotary caster 132 , so that the power generated from the motor 133 is efficiently transmitted to the rotary caster 132 . can In addition, a speed reducer 133b capable of reducing the speed of the motor 133 may be coupled to the motor 133, and a detailed description thereof will be provided 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 gasoline engines, additional components such as gasoline storage tanks, differential gears, and belts for power transmission are required. , there are many disadvantages in the work process.

However, the BLDC motor has a smaller size than a general motor, can reduce the overall weight of the lane painting apparatus 100, and has characteristics that the noise does not increase significantly even when used for a long time. In addition, when the rotary caster 132 rotates, difficulties such as the direction change of the rotary caster 132 is not immediately performed due to the motor 133 coupled to the rotary caster 132 may occur. However, since the motor 133 is provided as a BLDC motor, it is possible to minimize the occurrence of such a problem. In addition, due to the characteristics of the painting operation, a large amount of noise may be generated due to the painting operation. However, in the case of the lane painting apparatus 100 using a BLDC motor, the noise generated during operation is greatly reduced compared to a conventional painting apparatus using an engine. can do it

The painting unit 140 sprays paint to paint a road, and may include a paint dissolution tank 141 , a paint spreading 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 a liquid phase and then solidified at room temperature is mainly used, and in order to maintain a dissolved state, the paint must be stored at a temperature of about 180°C to 200°C. Heat is supplied from the gas supply member (141a) By receiving, the paint may be stored in the paint dissolution tank 141 while maintaining a temperature state of about 180 to 200 degrees, which is an appropriate storage temperature.

The paint spraying 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 be provided to protrude from the side surface of the painted body 111, and a spray guide 142a may be formed so that the paint can be sprayed at an accurate location on the road. have.

In detail, it is difficult to easily grasp that the paint is sprayed at the position of the operator who uses the lane painting apparatus 100, and it is confirmed whether the painting path coincides with the position of the painted lane while the lane painting apparatus 100 moves. There is something difficult to do. In order to overcome this point, a spray guide 142a is provided on the road to guide the location or the path where the paint is to be sprayed, so that the paint can be accurately sprayed at the location of the lane to be painted.

The reflector spraying member 143 sprays the reflector at the location where the paint is sprayed, that is, the painted location, and the reflector stored in the reflector storage container 143a may be sprayed 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 on the painted lane. In general, after the lane is painted, the reflector may be sprayed before the paint dries, and by spraying the reflector, visibility of the lane can be improved at night or in rainy weather, which can be caused by not recognizing the lane. 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.

6A and 6B , the motor driver 151 according to an embodiment of the present disclosure may control the output generated by the motor 133 by controlling the motor 133, and the painted body 111 may You can control the speed of movement, etc.

In an environment in which the worker uses a conventional painting device to paint lanes through manpower, the worker applies force on an uphill road or pulls the painting device on a downhill road to reduce or increase the speed of the painting device. 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, on an uphill road, the painted body 111 moves due to the weight of the main body 110 , the painting unit 140 , and the like. The speed may be slowed down, and on the contrary, the moving speed of the painted body 111 is inevitably increased on a downhill road.

When working in such a working environment, the motor driver 151 may control the motor 133 by receiving output amount information of the motor 133 from the motor output lever 123 .

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 , and a separately provided computer or the like is connected to the motor driver 151 . It can be connected so that the painted body 111 moves at 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 apparatus 100 from speeding up or from slipping.

That is, when the operator sets the output of the motor output lever 123 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 is also 0 m/s. When the speed of the wheel is not 0 m/s, it is possible to control to continuously check the output of the motor 133 set by the motor output lever 123 so that the speed of the wheel becomes 0 m/s.

Also, the motor driver 151 according to an embodiment of the present disclosure may control the moving speed of the painted body 111 .

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

As described above, by continuously checking the moving speed of the painted body 111, even though the operator 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 situation of slowing or speeding occurs, the moving speed of the painted body 111 may be increased by increasing the output of the motor 133 by the motor driver 151 . In addition, by reducing the output of the motor 133 by the motor driver 151 or by controlling the speed reducer 133b to reduce the rotation speed itself, it is possible to control the current movement speed to return to a preset movement speed.

In addition, the motor driver 151 according to an embodiment of the present disclosure recognizes a guide line marked on a road for painting as a sensor, thereby controlling the painted body 111 to automatically move along the guide line. can do. That is, even if the worker does not control the painted body 111 , the painting body 111 may automatically paint the lane while autonomously driving along the guide line.

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

That is, during the painting operation, even if the operator does not recognize the obstacle, or even if the operator does not make a decision to avoid the obstacle, when the obstacle is recognized by the obstacle detection sensor, the motor driver 151 immediately controls the output of the motor 133 . is controlled to 0% to adjust the speed value of the painted body 111 to 0, so that 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 appreciated that branch substitutions, transformations and alterations are possible.
