Description

The present invention relates to a compaction machine, and particularly relates to a technique for optimizing the spraying timing of water and liquid.

Rolling machines such as tire rollers are equipped with rolling rollers (for example, rolling tires and iron wheels) that also serve as wheels at the front and rear of the vehicle body in order to compact the paving material in road pavement work. ..
In such a rolling machine, the paving material is compacted by a rolling roller while traveling on a road surface covered with a paving material such as an asphalt mixture.

However, since the rolling roller comes into contact with the pavement material with a strong pressure, debris peeled off from the pavement material adheres to the surface thereof, which hinders the formation of a smooth road surface.
Therefore, a watering nozzle is arranged near the rolling roller to prevent the pavement material from adhering by sprinkling water from the watering nozzle to the outer peripheral surface of the rolling roller during the pavement work.

Further, a technique for saving water sprinkled from a watering nozzle to the outer peripheral surface of a rolling roller has been developed (Patent Document 1).

Japanese Unexamined Patent Publication No. 2015-203188

By the way, in such a compaction machine, it is known to spray a liquid agent such as an asphalt mixture adhering agent in addition to the water sprinkled from the watering nozzle. This liquid agent can prevent asphalt from adhering to the compaction roller even when the temperature difference between the compaction roller and the road surface is large (action by the liquid agent). If such spraying of the liquid agent is performed at the same time as watering, the liquid agent may be diluted and the action of the liquid agent may be reduced. In addition, if the liquid agent is sprayed more than necessary, there is a risk that the road surface will be roughened (reaction by the liquid agent).
Here, in view of the technique disclosed in Patent Document 1, the technique of saving water to be sprinkled is disclosed, but the technique of spraying a liquid agent is not disclosed, and there is room for further improvement.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a compaction machine capable of maintaining a good action by a liquid agent and suppressing a reaction caused by the liquid agent. ..

In order to achieve the above object, the compaction machine of the present invention includes a liquid agent spraying device for spraying a liquid agent on a rolling compactor roller provided in the machine body, a watering device for sprinkling water on the compaction roller, and the liquid agent spraying device. In a compaction machine including a controller for controlling the sprinkler, the controller is a recording unit for recording the number of compaction operations, which is the number of compaction operations performed by the aircraft per lane, and the aircraft. It has a turn-back determination unit that determines whether or not the traveling direction in the front-rear direction has been switched, and a roller rotation number calculation unit that determines the rotation speed of the rolling roller. If the number of rolling compactions recorded in the recording unit exceeds a predetermined number when it is determined that the direction has been switched, the sprinkler is stopped, the liquid spraying device is operated, and the roller rotation speed calculation unit is used. After a period of time during which the number of rotations of the rolling roller calculated by the above-mentioned is rotated a predetermined number of times , the liquid agent spraying device is stopped and the sprinkler is operated.

As a result, when the number of rolling compactions exceeds a predetermined number of times, only the liquid agent is sprayed for a period in which the number of rotations of the rolling rolling rollers rotates a specified number of times . By controlling the liquid agent spraying device and the watering device with a controller so that only watering is performed , the appropriate period for spraying the liquid agent on the rolling roller is accurately specified based on the rotation speed of the rolling roller, and the rolling compaction is performed. It is possible to control the timing of sprinkling and spraying water and liquid on the rollers by the controller without the operation of the operator.

As another aspect, a forward / backward operation device for operating the forward / backward movement of the aircraft is provided, and the turn-back determination unit is used when the forward / backward operation device passes through a neutral position located between the forward position and the reverse position. It is preferable to determine that the traveling direction of the aircraft in the front-rear direction has been switched.

As a result, it is possible to accurately determine the forward / backward operation of the aircraft by the operator by determining the forward / backward operation of the aircraft by the operator from the operation mode of the forward / backward operation device.

As another aspect, the controller includes an airframe speed calculation unit that calculates the speed of the airframe, and stops the sprinkler when the airframe speed calculated by the airframe speed calculation unit is 0 or equal to or higher than a specified speed. , It is preferable to stop the liquid spraying device.

As a result, when the speed of the aircraft is 0, in other words, when the aircraft is stopped, water sprinkling and spraying of the liquid agent are stopped, so that even if the determination by the turn-back determination unit is an erroneous determination, it is not possible. It is possible to stop sprinkling and spraying of necessary water and liquid.

In addition, even when the speed of the aircraft is higher than the specified speed, by stopping the sprinkling of water and the spraying of the liquid agent, for example, if the specified speed is inappropriate as the speed of the aircraft in the compaction work, in other words, the aircraft. It is possible to stop sprinkling water and liquids, such as when moving, instead of compacting, and when spraying is unnecessary. Will be done.

According to the compaction machine of the present invention, when the number of rolling compactions exceeds a predetermined number of times, only the liquid agent is sprayed for a period in which the number of rotations of the compaction roller rotates a specified number of times, and the number of rotations of the compaction roller becomes the specified number of times . Since the liquid agent spraying device and the watering device were controlled by the controller so that only water was sprayed after the rotation period had elapsed, the appropriate period for spraying the liquid agent on the compaction roller based on the rotation speed of the compaction roller was accurate. The timing of the liquid to be sprayed on the rolling roller can be controlled by the controller without the operation of the operator.

As a result, the action of the liquid agent can be kept good and the reaction of the liquid agent can be suppressed.

It is a flowchart which showed the routine which shows the control procedure of the spray control of the compaction machine which concerns on this invention, which is executed by the ECU.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
With reference to FIG. 1, a side view of the airframe 1 according to the present invention is shown.

The machine body 1 is a tire roller provided with a wheel 3, an operation unit 5, a watering device 7, and a liquid spraying device 8. This machine body 1 can be compacted in asphalt pavement work by performing compaction work described later. The wheel (rolling roller) 3 is a rubber tire, and is a rolling roller capable of traveling the machine body 1 by rotating with a drive device (not shown) and decelerating the body 1 by decelerating.

The watering device 7 is a spraying device capable of sprinkling water from the watering nozzle 7a to the wheels 3 by operating the watering device 7. The sprinkler 7 can sprinkle water stored in a water tank (not shown) installed in the frame 1a of the machine body 1.

The liquid agent spraying device 8 is a spraying device capable of spraying the liquid agent on the wheels 3 from the liquid agent nozzle 8a by operating. Here, the liquid agent is a so-called asphalt mixture adhering inhibitor that is sprayed to prevent asphalt from adhering when there is a temperature difference between the wheel 3 and the paved road surface, for example.

With reference to FIG. 2, a perspective view of the operation unit 5 as viewed from the rear of the machine body is shown. The operation unit 5 includes a forward / backward lever (forward / backward operation device) 11, a steering 13, a speedometer 15, and a spray setting unit 17. The operation unit 5 is a device for an operator to perform various operations such as traveling, steering, braking, watering, and spraying of the machine body 1.

The forward / backward lever 11 is a lever that controls an HST (Hydraulic Static Transmission) (not shown) by being operated by an operator and switches the traveling direction of the machine body 1 in the front-rear direction by changing the rotation direction of the wheels 3. The forward / backward lever 11 can be switched to three positions: a forward position, a neutral position, and a reverse position.

When the operator depresses the accelerator pedal 31 when the forward / backward lever 11 is in the forward position, the HST is controlled so that the aircraft 1 can move forward. Further, when the operator depresses the accelerator pedal 31 when the forward / backward lever 11 is in the reverse position, the HST is controlled so that the aircraft 1 can move in the backward direction. On the other hand, when the forward / backward lever 11 is in the neutral position, the HST is controlled so that the aircraft 1 does not accelerate even if the operator depresses the accelerator pedal 31.

The steering 13 is a steering device that is operated by an operator to rotate the wheels 3 on the front side of the machine around the vertical direction of the machine and adjust the traveling direction of the machine 1 in the left-right direction.
The speedometer 15 is a meter that displays the speed of the machine body 1 calculated from the rotation speed of the wheels 3 detected by, for example, the wheel speed sensor 3a provided in the vicinity of the wheels 3. The speedometer 15 also displays, for example, the rotation speed of an engine (not shown).

The spray setting unit 17 includes a sprinkler liquid agent interlocking switch 21 and a compaction number setting switch 23. The sprinkler liquid agent interlocking switch 21 is a changeover switch capable of switching ON / OFF of the sprinkler liquid agent interlocking control described later at will by the operator. The rolling compaction number setting switch 23 is a switch that allows an operator to select the number of rolling compaction operations (hereinafter referred to as the number of rolling compactions) performed by the machine per lane.

The ECU (controller) 40 is a control device for performing comprehensive control including engine operation control, and is an input / output device, a storage device (ROM, RAM, non-volatile RAM, etc.), and a central processing unit (CPU). Etc. are included in the configuration.

With reference to FIG. 3, the connection configuration of the ECU 40 is shown in a block diagram.
A wheel speed sensor 3a, a forward / backward lever 11, a sprinkler liquid agent interlocking switch 21, and a compaction number setting switch 23 are electrically connected to the input side of the ECU 40.

As a result, the wheel speed sensor 3a inputs the rotational speed information of the wheel 3, the forward / backward lever 11 inputs the forward / backward operation information by the operator, and the sprinkler liquid agent interlocking switch 21 inputs the rotational speed information to the ECU 40. The ON / OFF operation of the sprinkler liquid agent interlocking control is input, and the information on the number of rolling compactions by the operator is input from the compaction number setting switch 23.

On the other hand, the sprinkler 7 and the liquid spray device 8 are electrically connected to the output side of the ECU 40. As a result, the ECU 40 can control (ON, OFF) the watering device 7 and the liquid agent spraying device 8 to sprinkle and spray water and the liquid agent as appropriate.

The ECU 40 includes a wheel rotation speed calculation unit 42 and an airframe speed calculation unit 44 as calculation units, a turn-back determination unit 52 as a determination unit, and a recording unit 62 for recording calculations and determination results by each calculation unit and determination unit. Has been done.

The wheel rotation speed calculation unit 42 is a calculation unit capable of counting the rotation speed of the wheel 3 based on the rotation speed information of the wheel 3 input from the wheel speed sensor 3a.
The machine speed calculation unit 44 is a calculation unit capable of calculating the speed of the machine body 1 based on the rotation speed information of the wheels 3 input from the wheel speed sensor 3a.

The turn-back determination unit 52 determines that the turn-back determination unit 52 has turned back on the lane where the rolling compaction work, which will be described later, is performed when the forward / backward lever 11 is operated by the operator to switch the traveling direction of the machine body 1 in the front-rear direction. It is one.

With reference to FIG. 4, an explanatory diagram of the compaction work is shown. Further, with reference to FIGS. 5 and 6, a routine showing the control procedure of the spray control of the compaction machine according to the present invention, which is executed by the ECU 40, is shown in the flowchart. Hereinafter, the control procedure for spray control will be described with reference to FIGS. 4 to 6. For convenience of explanation, the compaction work in the entire section (section F) to be constructed is referred to as rolling compaction work.

According to FIG. 4, in the compaction work of the section F using the machine body 1, the section F is divided into a plurality of lanes such as the first lane, the second, ... Nth lane in advance, and for example, eight times per lane (setting). Number of times N), compaction work is performed. That is, in the rolling compaction construction, the machine body 1 reciprocates four times per lane. Hereinafter, the compaction work in one outward trip or one return trip is referred to as rolling compaction work.

According to FIG. 5, this routine starts when the sprinkler liquid agent interlocking switch 21 is turned on (step S1). At this time, the number of recordings X is also set to 0.
In step S10, it is determined whether or not the speed V of the machine 1 calculated by the machine speed calculation unit 44 is 0 km / h (hereinafter, simply referred to as 0). If it is determined that the determination result in step S10 is true (Yes) and the speed V of the aircraft 1 is 0, that is, it is determined that the aircraft 1 is stopped, the process proceeds to steps S55 and S60. Further, if it is determined that the determination result in step S10 is false (No) and the speed V of the aircraft 1 is not 0, that is, it is determined that the aircraft 1 is traveling, the process proceeds to step S15.

In step S15, it is determined whether or not the speed V of the machine 1 calculated by the machine speed calculation unit 44 is the speed limit Vmax. Here, the speed limit Vmax is, for example, the maximum speed as the speed of the machine body 1 in rolling compaction construction. When it is determined that the determination result in step S15 is true (Yes) and the speed V of the machine body 1 is faster than the speed limit Vmax, that is, it is determined that the machine body 1 is moving instead of being compacted, the steps S55 and The process proceeds to step S60. Further, when it is determined that the determination result in step S15 is false (No) and the speed V of the machine body 1 is equal to or less than the speed limit Vmax, that is, it is determined that the machine body 1 is being compacted, the process proceeds to step S20.

Therefore, in step S10 and step S15, it is determined whether or not the rolling compaction work is carried out, and if the rolling compaction work is not carried out, the process proceeds to steps S55 and S60, and the sprinkler 7 and the liquid agent The spraying device 8 is turned off to end this routine. As a result, it is possible to prevent the water and the liquid agent from being sprinkled or sprayed even when the machine body 1 has not been compacted.

In step S20, it is determined whether or not the turn-back determination unit 52 determines that the traveling direction of the aircraft 1 in the front-rear direction has been switched. Here, the turn-back determination unit 52 has moved the forward / backward lever 11 from the forward position or the reverse position to the opposite reverse position or the forward position by passing the neutral position from the forward position or the reverse position, for example, by the switching operation of the forward / backward lever 11 by the operator. Is detected, it is determined that the traveling direction of the aircraft 1 in the front-rear direction has been switched.

If it is determined that the determination result in step S20 is false (No) and the return determination unit 52 has not determined that the traveling direction in the front-rear direction of the aircraft 1 has been switched, the process proceeds to step S21 (A in FIGS. 5 and 6). , It is determined whether or not the liquid agent spraying device 8 is ON.

When it is determined that the determination result in step S21 is true (Yes) and the liquid agent spraying device 8 is ON, the process proceeds to step S100 described later (B in FIGS. 5 and 6). Further, if it is determined that the determination result in step S21 is false (No) and the liquid agent spraying device 8 is OFF, the process proceeds to step S22. When it is determined that the determination result in step S21 is true (Yes) and the liquid agent spraying device 8 is ON, for example, the liquid agent spray switch is operated by an operator during this routine to control the liquid agent regardless of this routine. It is a case of spraying.

In step S22, it is determined whether or not the sprinkler 7 is ON. When it is determined that the determination result in step S22 is true (Yes) and the sprinkler device 7 is ON, this routine is terminated (C in FIGS. 5 and 6). Further, when it is determined that the determination result in step S21 is false (No) and the sprinkler device 7 is OFF, the process proceeds to step S23, the liquid agent spraying device 8 is turned ON, and the process proceeds to step S100 described later (FIG. 5, FIG. 6 B). The case where the determination result in step S21 is false (No) and the sprinkler 7 is determined to be OFF is, for example, immediately after the start of this routine, and both spraying of the liquid agent and sprinkling of water are still performed. If you don't.

Therefore, in steps S21 to S23, it is determined whether or not the liquid agent is sprayed and watered (steps S21 and S22), and if watering is done (Yes in step S22), the machine 1 is in step S20. This routine is terminated in order to continue watering until the turn-back determination unit 52 determines that the traveling direction in the front-rear direction has been switched.
Further, even when the liquid agent is not sprayed, if the liquid agent is sprayed (Yes in step S21), the process proceeds to step S100 described later, and if the liquid agent is not sprayed (No in steps S21 and S22). ) Starts spraying the liquid agent (step S23), and then proceeds to step S100.
On the other hand, if the determination result in step S20 is true (Yes) and the return determination unit 52 determines that the traveling direction in the front-rear direction of the aircraft 1 has been switched, the process proceeds to step S30.

In step S30, the number of times the operator has added 1 to the number of times the rolling work in the current lane has been completed (recording number X) recorded in the recording unit 62 is selected by the operator by operating the rolling number setting switch 23. It is determined whether or not it is the same as the number of rolling compactions (hereinafter referred to as the set number of times N). Here, the number of times that 1 is added to the number of times of recording X is the number of times that the rolling compaction work is completed immediately after the folding back determination unit 52 determines that the traveling direction in the front-rear direction of the machine body 1 has been switched (hereinafter, the number of times of completion F). ).

The return determination unit 52 determines that the determination result in step S30 is true (No) and the number of completions F is not the same as the set number N, that is, the traveling direction of the aircraft 1 in the front-rear direction has been switched (Yes in step S20). If it is determined that the immediately preceding rolling work (hereinafter referred to as the previous rolling work) was not the last rolling work in the current lane, the process proceeds to step S40. When it is determined that the determination result in step S30 is true (Yes) and the number of completions F is the same as the set number of times N, that is, the previous compaction work is the last compaction work in the current lane, the process proceeds to step S70.

Therefore, in step S30, it is possible to determine whether or not the pre-rolling work is the last rolling work in the current lane by determining whether or not the number of completions F is the same as the set number of times N.

In step S40, 1 is added to the number of recordings X to proceed to step S50, the sprinkler 7 is turned on, and this routine is terminated.
As a result, the number of rolling compactions can be counted by adding 1 to the number of rolling compaction operations in the current lane (step S40). Further, by turning on only the watering device 7 (step S50), it is possible to suppress the saving of the liquid agent and the reduction of the effect of the liquid agent due to the mixture of the water and the liquid agent while sprinkling water on the wheel 3.

On the other hand, in step S70, which shifts when the determination result of step S30 is true (Yes), the number of recordings X is set to 0, that is, reset to step S80, the sprinkler 7 is turned off, and the transition to step S90 is performed. The liquid agent spraying device 8 is turned on, and the process proceeds to step S100.

In this way, by resetting the number of recordings X (step S40), the number of rolling compactions can be counted again from the current number of rolling compactions. Further, by turning off the watering device 7 (step S80) and turning on the liquid agent spraying device 8 (step S90), the liquid agent is sprayed on the wheel 3 while the water and the liquid agent are mixed to reduce the effect of the liquid agent. It can be suppressed.

In step S100, it is determined whether or not the wheel rotation speed at which the wheel 3 has rotated after step S90 has rotated by a predetermined number of times R or more, based on the rotation speed of the wheel 3 calculated by the wheel rotation speed calculation unit 42. Here, the specified number of times R is the number of rotations of the wheel 3 suitable for spraying the liquid agent on the wheel 3 in a necessary and sufficient manner, and is, for example, one rotation.

After repeating step S100 until it is determined that the determination result of step S100 is true (Yes) and the wheel 3 is sufficiently sprayed with the liquid agent, the process proceeds to step S110, the liquid agent spraying device 8 is turned off, and the process proceeds to step S50. Then, the sprinkler 7 is turned on to end this routine. If the aircraft 1 is stopped while the step S100 is repeated, the process may proceed to the step S110 even if the determination result of the step S100 is false (No).

Therefore, in steps S80 to S110 and S50, spraying of the liquid agent only (steps S80 and S90) is carried out until the wheel 3 rotates R a specified number of times (step S100), and then watering only of water (steps S110 and S50). ). As a result, after spraying the necessary and sufficient liquid agent, only water can be sprayed, and an appropriate amount of the liquid agent can be sprayed regardless of the operator.

Further, by controlling the number of rolling compactions in steps S30, S40 and S70 as described above, it is possible to manage the timing of spraying the liquid agent for each number of rolling compactions in the current lane.

In the present embodiment, since the liquid agent is sprayed when the number of completions F becomes the same as the set number of times N as in step S30, the liquid agent is sprayed on the wheels 3 during the first compaction work in each lane, and thereafter. Sprinkle only water until you change lanes. As a result, by preventing unnecessary spraying of the liquid agent, it is possible to save the liquid agent and improve the accuracy of the construction road surface.

When the sprinkler liquid agent interlocking switch 21 is turned ON (step S1), when the spray control is executed so as to start this routine after sprinkling water, the sprinkler liquid interlocking switch 21 is turned ON. At that time, the process may first proceed to step S50, and then the above spray control may be executed.

As described above, in the compaction machine according to the present invention, the liquid agent spraying device 8 for spraying the liquid agent on the wheels 3 provided in the machine body 1, the watering device 7 for sprinkling water on the wheels 3, the liquid agent spraying device 8 and the liquid agent spraying device 8 In the compaction machine provided with the ECU 40 for controlling the sprinkler device 7, the ECU 40 has a recording unit 62 for recording the number of recordings X, which is the number of compaction operations performed by the aircraft 1 per lane, and the front and rear of the aircraft 1. It has a turn-back determination unit 52 that determines whether or not the travel direction in the direction has been switched, and records in the recording unit 62 when it is determined by the turn-back determination unit 52 that the travel direction in the front-rear direction of the machine 1 has been switched. When the number of recordings X exceeds the set number N, the watering device 7 is stopped and the liquid spraying device 8 is operated, and after a certain period of time, the liquid spraying device 8 is stopped and the watering device 7 is operated.

Therefore, when the number of recordings X exceeds the set number N because the number of completions F obtained by adding 1 to the number of recordings X and the set number N become the same value, only the liquid agent is sprayed for a certain period of time, and after a certain period of time has elapsed. Since the liquid agent spraying device 8 and the watering device 7 are controlled by the ECU 40 so as to only sprinkle water, the timing of the liquid agent sprayed on the wheels 3 can be managed by the ECU 40 without the operation of the operator.

A forward / backward lever 11 for operating the forward / backward movement of the machine body 1 is provided, and the folding back determination unit 52 receives the front / rear movement of the machine body 1 when the forward / backward movement lever 11 passes through a neutral position located between the forward position and the reverse position. It is determined that the traveling direction in the direction has been switched.
Therefore, since the forward / backward operation of the machine 1 by the operator is determined from the operation mode of the forward / backward lever 11, the forward / backward operation of the machine 1 by the worker can be accurately determined.

The ECU 40 includes a wheel rotation speed calculation unit 42 for determining the rotation speed of the wheel 3, and a fixed period is a period in which the rotation speed of the wheel 3 calculated by the wheel rotation speed calculation unit 42 rotates R a predetermined number of times. ..
Therefore, since the liquid agent spraying device 8 and the sprinkler device 7 are controlled by the ECU 40 so that only spraying is performed while the rotation speed of the wheel 3 calculated by the wheel rotation speed calculation unit 42 rotates R a specified number of times, the wheel 3 It is possible to accurately specify an appropriate period for spraying the liquid agent on the wheel 3 based on the rotation speed.

Then, the ECU 40 includes an airframe speed calculation unit 44 that calculates the speed of the airframe 1, and when the speed of the airframe 1 detected by the airframe 1 speed calculation unit is 0 or the speed limit Vmax or more, the sprinkler 7 is stopped. The liquid agent spraying device 8 is stopped.
Therefore, when the speed of the aircraft 1 is 0, in other words, when the aircraft 1 is stopped, the sprinkling of water and the spraying of the liquid agent are stopped, so that even if the determination by the return determination unit 52 is an erroneous determination, the determination is erroneous. It is possible to stop sprinkling and spraying unnecessary water and liquids.
Further, even when the speed of the machine 1 is equal to or higher than the speed limit Vmax, the sprinkling of water and the spraying of the liquid agent are stopped. Therefore, for example, when the speed limit Vmax is an inappropriate speed as the speed of the machine 1 in the compaction work. In other words, when the machine 1 is not rolling, but is moving, water and liquid are sprinkled, and when spraying is unnecessary, water and liquid are sprinkled and sprayed is stopped. be able to.

This concludes the description of the compaction machine according to the present invention, but the present invention is not limited to the above embodiment and can be changed without departing from the gist of the present invention.
For example, in the present embodiment, the liquid agent is sprayed on the wheel 3 for a certain period during the first compaction work in the current lane, but the liquid agent is sprayed at the beginning of each compaction work or twice or more in each lane. Alternatively, the period may be changed according to the type of the liquid agent, the temperature of the road surface, and the like.

Further, in the present embodiment, the forward / backward movement operation of the machine body 1 is determined from the operation mode of the forward / backward movement lever 11, but the determination may be made from the speed of the machine body 1.

Further, in the present embodiment, the forward / backward switching operation of the machine body 1 is determined from the operation of the forward / backward lever 11, but the operation unit 5 is provided with a return button that is pressed every time the operator finishes the rolling work, for example. , The forward / backward switching operation of the machine 1 may be determined from the operation of the turn-back button.

Further, in the present embodiment, the control procedure of the spray control has been described based on the flowchart of FIG. 5, but the order of each step may be changed as appropriate.
