Japanese Patent Publication No. 7-62325

  The road marking line coating apparatus used for the construction of road marking lines with such convex ribs includes, for example, (a) a convex rib forming apparatus that sequentially forms convex ribs protruding at a predetermined height on a road surface at a predetermined formation pitch. (B) The carriage is equipped with a connecting line coating device that is located behind the convex rib forming device and applies a coating material to the road surface to form a connection line connecting the convex ribs on the road surface.

The CPU 70 processes input signals from the main operation panel 78a, the reproduction remote operation panel 78b, and the encoder 80 in accordance with a program stored in the ROM 74 in advance using the temporary storage function of the RAM 72, and the convex rib B and the connection line C. The air cylinders 48, the air cylinder 62, the mist shutter open / close electromagnetic valve MV2, the rib slit open / close electromagnetic valve MV4, the rib shutter open / close electromagnetic valve MV5, etc. for operating the air cylinder 66 are automatically controlled. The information necessary for the operator is displayed on the display 82. The encoder 80 is operatively connected to the wheel 12 in order to detect the position of the carriage 18, that is, the rotary spray coating device 24 and the slit type convex rib forming device 26 with respect to the road surface 52 or the movement distance of the carriage 18.

The application start timing of the connection line C is, for example, the timing after the carriage 18 has moved by the interval L from the completion of the formation of the predetermined convex rib B. The basic control flow includes the slit-type convex rib forming device 26 and the convex rib formation control means that sequentially forms the convex ribs B on the road surface 52 at a predetermined constant pitch, and the convex ribs B that have passed through. In order to connect from the rear end portion to the front end portion of the next approaching convex rib B, the formed convex rib B starts application of the coating material immediately after passing through the rotary spray coating device (connecting wire coating device) 24. and, in response that the connection line application control means for constant application interval L _C to form a connection line C to terminate the coating after the lapse which is shorter than that depending on the formation pitch L _0.

  FIG. 8 is a flowchart for explaining a main part of the control operation of the electronic control device 28 at the time of line regeneration based on the operation in the automatic operation mode, that is, re-construction. In FIG. 8, in a step (hereinafter, step is omitted) S1 corresponding to the convex rib formation completion determining means, it is determined whether or not the formation of the predetermined convex rib B is completed by the slit type convex rib forming device 26. . If the determination at S1 is negative, the routine is terminated. If the determination is affirmative, the formation of the predetermined convex rib B is completed at S2 corresponding to the first storage means or the first storage step. The position of the carriage 18 at the time, that is, the first carriage position P1 is stored. Next, in S3, it is determined whether or not the regeneration start switch PB1 is pressed to the ON state. The operation of pressing the regeneration start switch PB1 to the ON state is a preparatory operation for applying a new convex rib B just above the existing convex rib B that has been previously constructed and consumed. It is operated in the section after the formation is completed and before the formation position of the new convex rib B to be applied next. If the determination in S3 is negative, this routine is terminated. If the determination is affirmative, in S4 corresponding to the canceling unit or the canceling process, the convex rib formation control unit temporarily forms the convex rib. A command to stop or wait is output.

  Next, in S5, it is determined whether or not the pressing operation of the regeneration start switch PB1 has been released and returned to the OFF state. The release operation of the regeneration start switch PB1 is operated by an operator at a timing at which application of a new convex rib B is to be started immediately above an existing convex rib B that has been previously constructed and consumed. If the determination in S5 is negative, this routine is terminated. If the determination is affirmative, in S6 corresponding to the convex rib formation command means or the convex rib formation command process, the convex ribs that have been canceled until then. And the formation of the convex rib B by the slit type convex rib forming device 26 is started immediately. Thereby, the new convex rib B is apply | coated just above the existing convex rib B which was constructed and consumed previously. At the same time, in S7 corresponding to the second storage means or the second storage step, the second carriage position P2, which is the position of the carriage 18 when the regeneration start switch PB1 is turned off, is stored.

The formation S8 and S9, corresponding to the timing correction means or forming timing correction process is performed, the convex rib forming control means and connecting lines actuated by being formed pitch L ₀ and applied to be used in the basic control flow as application control unit section _{L C} is corrected. That is, in S8, the formation pitch L ₀ between the convex rib B formed immediately before the new convex ribs B formed by a command the new convex rib B is calculated in S6, the calculated formation pitch L ₀ is updated as the formation pitch L ₀ of the convex rib formation control means.

In S9, the distance d between the second carriage position P2 and the first carriage position P1 when the regeneration start switch PB1 as the second operation input is turned off is calculated, and the distance is calculated as the connection line application control. It is updated (corrected) as the spray distance of the means (application section L _C of the connecting line C). As a result, after the carriage 18 has moved by the interval L from the completion of the formation of the new convex rib B, injection by the rotary spraying application device 24 is started, and after the carriage 18 has moved by the injection distance, that is, the next convex After the carriage moves from the formation start point of the rib B by the distance L, the injection is terminated. If the interval between the existing convex ribs B that have been previously constructed and consumed on the road surface 52 is not constant, the regeneration start switch PB1 is turned on and off each time, and the re-execution control routine of FIG. Is executed.

9 and 10 are time charts for explaining the operation of the electronic control unit 28. FIG. Figure 9 shows the operation when forming the pitch L ₀ of the convex rib B are relatively short distance, for example, about 300 mm. In this case, the formation pitch L ₀ of the convex ribs B is smaller than the interval L between the spray position of the rotary spray coating device 24 and the coating position of the slit convex rib forming device 26, and is due to the spray of the rotary spray coating device 24. Two convex ribs B are formed before the start of application. Figure 10 shows a case forming pitch L ₀ of the convex rib B is relatively long distances, for example, about 500 mm. In this case, the formation pitch L ₀ of the convex ribs B is larger than the interval L between the spray position of the rotary spray coating device 24 and the coating position of the slit convex rib forming device 26, and is due to the spray of the rotary spray coating device 24. A second convex rib B is formed after the start of application.

In FIG. 9, the distance d between the convex ribs B formed sequentially in response to the OFF operation of the regeneration start switch PB1 at the time of re-construction (= the first carriage position P1 when the formation of the convex ribs B is completed and the OFF operation time. Assuming that the distance between the second carriage position P2) is d ₁₁ , d ₁₂ , and d ₁₃ in this order, the values of the application section L _C of the connecting line C connecting the convex ribs B are d ₁₁ , are _{d 12,} d _13. Similarly, in FIG. 10, the distance d between the convex ribs B sequentially formed in response to the OFF operation of the regeneration start switch PB1 at the time of re-construction (= OFF with the first carriage position P1 when the formation of the convex rib B is completed) the distance between the second carriage position P2 during the operation) is assumed to be _{d 21,} d _22, d ₂₃ in this order, the value of the coating section L _C of the connecting line C which connects between them the projecting rib B in turn are _{d 21, d 22, d 23} .

As described above, according to the present embodiment, S2 (first storage step or first storage means) that stores the first carriage position P1 when the formation of the predetermined convex rib B is completed, and the predetermined convex rib. S4 (stopping process or stopping means) for temporarily stopping the convex rib forming operation by the slit type convex rib forming device 26 in response to the ON operation (first operation input) of the regeneration start switch PB1 after the formation of B is completed. In response to an OFF operation (second operation input) of the regeneration start switch PB1 for forming a new convex rib B just above the already-constructed convex rib B, cancellation of the convex rib forming operation by S4 is canceled. Then, in S6 (a convex rib formation command process or a convex rib formation command means) for forming a new convex rib B by the slit type convex rib forming device 26, and at the second carriage positions P2 and S2 at the time of the second operation input. Remembered second It calculates the distance d between the carriage positions P1, to correct the distance d as a coating section L _C of the connecting line C formed by the rotating jet coating apparatus (connecting line coating device) 24 S9 (forming timing correction step Alternatively, formation timing correction means) is provided in the electronic control unit 28. According to the re-construction operation of the road marking line with convex ribs by the slit-type convex rib forming device 26 provided with such an electronic control device 28, the second operation is performed in S9 (formation timing correction step or formation timing correction means). A distance d between the second carriage position P2 at the time of input and the first carriage position P1 stored in S2 (the first storage step or the first storage means) is calculated, and the distance d is calculated as a rotary spray application device ( from being modified as a coating section L _C of the connecting line C formed by the connecting line coating device) 24, to form a new convex rib B just above the convex rib B already construction during reapplication by performing the first operation input to perform further second operation input after the second operation input causes the formation pitch L ₀ of forming pitch L ₀ as the new convex ribs B of previously construction the convex ribs B are coincident And when , The coating interval L distance d of the connecting line C due to the connection line application control means between the second carriage position P2 to the first carriage position P1 at the time of completing the formation of the second time operation input convex rib B _Since it correct | amends as _C , between the said convex ribs B in re-construction will come to be connected suitably by the connection line C.

Further, according to this embodiment, the S9 (formation timing correction step or formation timing correction means) is a new convex rib B formed by the command of the S6 (convex rib formation command step or convex rib formation command means). And the formation pitch L ₀ of the convex rib B formed immediately before the new convex rib B is calculated, and the formation pitch L ₀ is updated as the formation pitch of the convex rib B by the convex rib formation control means. Therefore, after that, new convex ribs are repeatedly and automatically formed based on the updated formation pitch.
