It is possible to calculate the locus of the tire roller 1 based on the position coordinates that change with the passage of time in a 56 (hereinafter abbreviated as PC), calculate the number of times of rolling N etc. ing.

A roller temperature sensor (compressed pressure environment detecting means) 70 and a road surface temperature sensor (compressed pressure environment detecting means) 72 are provided in the vicinity of the pressure roller 3 r of the machine body 5.
The roller temperature sensor 70 is a sensor that detects the surface temperature of the pressure roller 3r without contact. Similarly to the roller temperature sensor 70, the road surface temperature sensor 72 is also a sensor that detects the surface temperature of the road surface 13 without contact.

An ECU (control device) 80 is a control device for performing comprehensive control including operation control of an engine (not shown), and is an input / output device, a storage device (ROM, RAM, non-volatile RAM, etc.), central processing unit (CPU) etc. are comprised.
Referring to FIG. 3, a connection configuration of the ECU 80 related to control of the tire roller 1 according to the present invention is shown in a block diagram.

  The operation panel 52, the roller temperature sensor 70, the road surface temperature sensor 72, and the pressure control unit 11 are electrically connected to the input side of the ECU 80. From the operation panel 52, the operation of turning on the watering button 52a, asphalt type The type of the liquid 23 stored in the liquid tank 22 is input, the temperature of the roller 3r is detected from the roller temperature sensor 70, the temperature of the road 13 is detected from the road temperature sensor 72, and the compression management is performed.

Thus, the liquid agent 23 can be supplied from the liquid agent tank 22 to the water sprinkling unit 9, and the flow rate of the liquid agent 23 is adjusted by controlling the liquid agent flow control valve 36, in other words, the supply amount of the liquid agent 23 to the water 21 is adjusted. be able to.

Referring to FIG. 4, a flowchart showing a control procedure of the tire roller 1, which is executed by the ECU 80 according to the first embodiment, is shown by a flowchart, which will be described below along the flowchart.
This routine starts when it is detected that the water spray button 52a is turned on by the operator.

In step S10, the water pump 30 and the liquid pump 34 are turned on, and the process proceeds to step S12.
In step S12, the basic value C0 of the opening degree of the liquid agent flow control valve 36 is determined from the type of asphalt set by the operator and the type of liquid 23 stored in the liquid tank 22 detected by the operation panel 52. The valve is opened and opened based on the set basic value C0. The opening degree of the liquid agent flow control valve 36 shown in this routine is 100% when the liquid agent flow control valve 36 is fully opened. For example, when the basic value C0 is 3%, the liquid agent flow control valve 36 It is assumed that the liquid agent flow control valve 36 is opened at an opening degree corresponding to 3% when fully open. The same applies thereafter.

Referring to FIG. 5, a correspondence table of basic values C0 of the opening degree of the liquid agent flow control valve 36 set based on the type of asphalt and the type of liquid 23 stored in the liquid tank 22 is shown.
That is, in step S12, values corresponding to the type (A, B or C) of asphalt detected by the operation panel 52 and the type (X, Y or Z) of the liquid 23 stored in the liquid tank 22 are basic It is determined that the value is C0, and the liquid agent flow control valve 36 is opened at an opening degree corresponding to the basic value C0. For convenience of explanation, the opening degree of the liquid agent flow control valve 36 at this time is referred to as a first opening degree D1.

Referring back to FIG. 4, after the liquid agent flow control valve 36 is opened at the opening degree corresponding to the basic value C0 in step S12, the process proceeds to step S14.
In step S14, it is determined whether or not the number of times of rolling based on the position coordinates of the tire roller 1 at the time of execution of the flow (for convenience of explanation, simply referred to as "the number of times of rolling N") is 2 or less (a fixed number of times). When it is determined that the number of times N of compression detected by the compression management unit 11 is 2 or less, the liquid agent flow control valve 36 opened at the first opening degree D1 is further opened by 10%, and the process proceeds to step S18. Do. On the other hand, when it is determined that the number of times of compression N detected by the compression management unit 11 is greater than two, step S18 is performed without changing the opening degree of the liquid agent flow control valve 36 opened at the first opening degree D1. Migrate to For convenience of explanation, the opening degree of the liquid agent flow control valve 36 at this time is referred to as a second opening degree D2.

  That is, in step S14 and step S16, when it is determined that the number N of compactions is 2 or less, in other words, when the number N of compactions is small, the asphalt laid on the road surface 13 may not be compacted yet and may be soft. Because there is a risk that asphalt adheres to the roller rollers 3f and 3r, the liquid agent flow control valve 36 opened at the first opening degree D1 is further opened by 10% in order to supply the liquid agent 23 more. There is.

  In step S18, it is determined whether the temperature of the pressure roller 3r is less than or equal to a specified temperature T1. When it is determined that the temperature of the pressure roller 3r detected by the roller temperature sensor 70 is lower than or equal to the specified temperature T1, the liquid agent flow control valve 36 is further opened 20% from the second opening degree D2, and the process proceeds to step S26. When it is determined that the temperature of the pressure roller 3r detected by the roller temperature sensor 70 is higher than the specified temperature T1, the process proceeds to step S22.

  In step S22, it is determined whether the difference between the road surface temperature and the temperature of the pressure roller 3r is larger than a predetermined temperature T2. When it is determined that the difference between the temperature of the road surface 13 detected by the road surface temperature sensor 72 and the temperature of the pressure roller 3r detected by the roller temperature sensor 70 is larger than the predetermined temperature T2, the liquid agent flow control valve 36 is opened second The valve is further opened by 5% from the degree D2, and the process proceeds to step S26. When it is determined that the difference between the temperature of the road surface 13 detected by the road surface temperature sensor 72 and the temperature of the pressure roller 3r detected by the roller temperature sensor 70 is the predetermined temperature T2 or less, the liquid agent flow control valve 36 It transfers to step S26, without changing from D2.

  That is, in step S18 to step S24, for example, assuming that the minimum temperature during general construction of asphalt is the specified temperature T1, when it is determined that the temperature of the pressure roller 3r is less than the specified temperature T1, the pressure roller 3f, Since the temperature of 3r is low and asphalt may adhere to the pressure roller 3f, 3r, the solution flow control valve 36 opened at the second opening degree D2 is further opened by 20% to supply the solution 23 more. I'm talking. Further, even when it is determined that the temperature of the pressure roller 3r is higher than the specified temperature T1, when the temperature difference between the road surface temperature and the pressure rollers 3f and 3r is equal to or more than the predetermined temperature T2, the pressure difference is generated due to the temperature difference. Since asphalt may adhere to the rollers 3f and 3r, the liquid agent flow control valve 36 opened at the second opening degree D2 is further opened by 5% in order to supply the liquid agent 23 more.

In step S26, the water shutoff valve 32 is opened, the mixed liquid is sprayed from the water spray nozzles 24, 24 onto the pressure roller 3f, 3r, and the present routine is ended.
As described above, by setting and adjusting the opening degree of the liquid agent flow control valve 36 in step S12 to step S24, it is possible to adjust the amount of the liquid agent 23 so as to be a mixed liquid having a concentration suitable for the pressure reduction condition. It has become.
After this routine ends, this routine is repeatedly executed while the water spray button 52a is turned on by the operator.

  As explained above, in the pressure conversion machine according to the first embodiment, the liquid agent tank 22 capable of storing the liquid agent 23, the water tank 20 capable of storing the water 21, and the pressure roller provided at the front and back of the machine body 5. 3f, 3r, water sprinkling nozzles 24, 24 provided at positions where the water 21 and the liquid agent 23 can be dispersed to the pressure roller 3 f, 3 r, and water 21 can be supplied from the water tank 20 to the water sprinkling nozzles 24, 24 The liquid introduction path 40, the liquid agent supply path 44 which connects the liquid agent 23 so as to be able to supply the liquid agent 23 from the liquid tank 22 to the water introduction path 40, and the liquid agent which adjusts the flow rate of the liquid agent 23 supplied from the liquid agent supply path 44 to the water introduction path 40 A flow control valve 36, a compression environment detection means for detecting a compression environment, and an ECU 80 capable of controlling the liquid flow control valve 36 are provided. The ECU 80 is detected by the compression environment detection means. In a compacted environment Flip the liquid flow control valve 36 is opened and closed controlled.

  Therefore, the flow rate of the liquid 23 supplied from the liquid tank 22 through the liquid supply path 44 is adjusted by opening and closing the liquid flow control valve 36 according to the compaction environment detected by the compaction environment detecting means. Since the liquid agent 23 is mixed with the water 21 supplied from the water tank 20 to the water spray nozzles 24 and 24 through the water introduction passage 40, the amount of the liquid agent 23 is adjusted according to the rolling pressure environment. A mixed solution of concentration can be sprayed from the water spray nozzles 24,24.

  The roller pressure environment detecting means includes a roller temperature sensor 70 for detecting the temperatures of the roller compacting rollers 3f and 3r, and the ECU 80 is configured to detect the temperature of the roller pressure rollers 3f and 3r detected by the roller temperature sensor 70 at a prescribed temperature T1. When determining as below, the liquid agent flow control valve 36 is controlled in the valve opening direction.

  Therefore, when it is determined that the temperature of the pressure roller 3f, 3r detected by the roller temperature sensor 70 is equal to or lower than the specified temperature T1, that is, the temperature of the pressure roller is low and asphalt easily adheres, Since the valve 36 is controlled in the valve opening direction, the amount of the liquid agent 23 can be adjusted according to the temperature of the pressure roller 3f, 3r, and the mixed liquid having an appropriate concentration can be sprayed from the water spray nozzles 24, 24. .

  The roller pressure environment detecting means includes a road surface temperature sensor 72 for detecting the temperature of the road surface 13. The ECU 80 is detected by the temperatures of the roller rollers 3f and 3r detected by the roller temperature sensor 70 and the road surface temperature sensor 72. When it is determined that the difference between the temperature of the road surface 13 and the temperature of the road surface 13 is greater than the predetermined temperature T2, the liquid agent flow control valve 36 is controlled in the valve opening direction.

  Therefore, the difference between the temperature of the pressure roller 3f, 3r detected by the roller temperature sensor 70 and the temperature of the road surface 13 detected by the road surface temperature sensor 72 is larger than the predetermined temperature T2, ie, the temperature of the pressure roller 3f, 3r When it is determined that the temperature difference between the temperature of the road surface 13 and the temperature of the road surface 13 is large and asphalt is likely to be attached, the liquid agent flow control valve 36 is controlled in the valve opening direction. The amount of the liquid agent 23 can be adjusted according to the temperature difference between the temperature of the road surface 13 and the road surface 13, and the mixed liquid having an appropriate concentration can be sprayed from the water spray nozzles 24, 24.

  Further, the compaction environment detection means includes the operation panel 52 capable of inputting the type of asphalt laid on the road surface 13 at the intention of the operator, and the ECU 80 inputs the type of asphalt laid on the road surface 13 inputted by the operation panel 52 The liquid agent flow control valve 36 is controlled to open and close according to the type.

  Therefore, according to the type of asphalt laid on the road surface 13 inputted to the operation panel 52 by the operator's intention, the liquid flow control valve 36 is controlled to open and close to adjust the concentration of the liquid 23 of the mixed liquid. The amount of the liquid agent 23 can be adjusted according to the type of asphalt, and a mixed solution of an appropriate concentration can be sprayed from the water spray nozzles 24, 24.

  Further, the pressure reduction environment detection means includes an operation panel 52 capable of inputting the type of the liquid agent 23 stored in the liquid agent tank 22 at the intention of the operator, and the ECU 80 stores the liquid agent tank 22 detected by the operation panel 52 The liquid agent flow control valve 36 is controlled to open and close in accordance with the type of the liquid agent 23 being processed.

  Therefore, according to the type of the liquid 23 stored in the liquid tank 22 inputted to the operation panel 52 by the operator's intention, the liquid flow control valve 36 is controlled to open and close to adjust the concentration of the liquid 23 of the mixed liquid. Since the amount of the liquid agent 23 is adjusted according to the type of the liquid agent 23 stored in the liquid agent tank 22, the mixed liquid having an appropriate concentration can be sprayed from the water spray nozzles 24, 24.

  And, the compaction environment detection means includes the compaction management unit 11 that detects the number of compactions N of each of the paving construction road surfaces 13, and the ECU 80 calculates the compaction pressure of each of the paving construction road surfaces 13 detected by the compaction management unit 11. When it is determined that the number N is two times or less, the liquid agent flow control valve 36 is controlled in the valve opening direction.

  Accordingly, in an environment where the asphalt is soft and easily adheres to the roller compacting rollers 3f and 3r because the number of times of roller compaction N at each location of the paving work road surface 13 detected by the roller compacting management unit 11 is two or less When it is determined that the liquid agent flow control valve 36 is controlled in the valve opening direction, the amount of the liquid agent 23 is adjusted according to the number N of times of compaction, and the mixed liquid of an appropriate concentration is sprinkled with water.

The water flow control valve 136 adjusts the flow rate of the water 21 supplied to the water amount adjustment unit 26 in the same manner as the liquid agent flow control valve 36. That is, when the water pump 30 operates, the flow rate of the water 21 supplied to the water amount adjustment unit 26 through the water introduction passage 40 is adjusted by the water flow control valve 136 and supplied from the liquid agent supply passage 144 to the water introduction passage 40 The liquid 23 to be mixed is mixed upstream of the water shutoff valve 32.

Referring to FIG. 7, a connection configuration of the ECU 80 related to control of the tire roller 1 according to the second embodiment is shown in a block diagram.
The difference from the first embodiment is that the water flow control valve 136 is electrically connected to the output side of the ECU 80. That is, by controlling the water flow control valve 136, the flow rate of the water 21 can be adjusted.

Referring to FIG. 8, a flowchart of a control procedure of the tire roller 1 executed by the ECU 80 according to the second embodiment is shown.
The difference from the first embodiment is that after step S12, the process proceeds to step S113 to set the opening of the water flow control valve 136 to 100% (fully open) and step S18 after step S14 or step S16. Before proceeding to step S, the process proceeds to step S117 to determine whether the roller pressure is higher than the set temperature T3. When determining that the temperature is lower than the set temperature T3, the process proceeds to step S119 and the water flow control valve 136 is opened. The degree is 10% lower than the fully open condition. Here, the set temperature T3 is a value lower than the specified temperature T1.

Specifically, in step S113, the opening degree of the water flow control valve 136 is set to 100% as in the case where the liquid agent flow control valve 36 is opened at the first opening degree D1 in step S12, and the process proceeds to step S14. In step S117, it is determined whether the temperature of the pressure roller 3r is less than or equal to the set temperature T3. When it is determined that the temperature of the pressure roller 3r detected by the roller temperature sensor 70 is equal to or lower than the set temperature T3, the process proceeds to step S119 and the water flow control valve 136 is closed 10% from the current opening degree. After setting the opening degree of the flow control valve 136 to 90%, the process proceeds to step S20. When it is determined that the temperature of the pressure roller 3r detected by the roller temperature sensor 70 is higher than the set temperature T3, the process proceeds to step S18.
Thereby, the opening degree of the water flow control valve 136 is set to 90% in step S119 to reduce the amount of water 21, thereby reducing loss of heat from the pressure rollers 3f and 3r to the water 21 and thus, it is possible to quickly convert The temperature of the pressure rollers 3f, 3r can be raised.

As described above, in the compressor of the second embodiment, the water flow rate control valve 136 that can be controlled by the ECU 80 is adjusted to adjust the flow rate of the water 21 supplied from the water tank 20 to the sprinkle nozzles 24, 24. Furthermore, it has.
Therefore, since the water flow rate control valve 136 is controlled by the ECU 80 to adjust the flow rate of the water 21 supplied from the water tank 20 to the sprinkle nozzles 24, 24, saving of the water 21 in the water tank 20 or The concentration of the liquid agent 23 can be increased by reducing the amount of 21.

Although the explanation of the roller compacting machine according to the present invention is finished above, 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 temperatures of the pressure roller 3r and the road surface 13 are detected by the roller temperature sensor 70 and the road surface temperature sensor 72. May be input.

  In the present embodiment, the water 21 is used as the second liquid. However, the water 21 may be replaced with a liquid of another type than the liquid 23.
