The glass bead spreading mechanism 7a includes a fixed abutment plate 22 having an end surface in which a pair of slit holes 22a disposed in the vicinity of one end of the receiving plate 21 is formed in an arc shape, The fixed holding plate 22 is configured by a pair of adjustment holding plates 25 that are movably attached opposite to each other with the receiving plate 21 interposed therebetween through a slit hole 22a, bolts 23, and nuts 24. Yes.
[0015]
Since the end face of the fixed abutment plate 22 is formed in an arc shape, the end portions 25b of the pair of adjustment abutment plates 25 can be moved away from each other. Immediately after the application of the marking line 13, it can be spread uniformly and widely. Reference numeral 26 denotes an L-shaped cover member attached to the end face of the fixed holding plate 22 with a hinge 27 as shown in FIG. 8, and can prevent the glass beads from being scattered by being tilted forward.
[0016]
Next, the operation of the glass bead spreading device in the road marking line coating machine according to the present invention will be described. FIG. 5 and FIG. 9 are diagrams showing a state when glass beads are dispersed in a narrow width. First, the bolts 23 and nuts 24 are loosened and moved so that the end portions 25b of the pair of adjustment abutment plates 25 approach each other, and then the pair of adjustment abutment plates 25 are tightened with the bolts 23 and the nuts 24 to fix the fixed abutment plate. 22 is fixed. When set in such a state, the glass beads 14 sprayed and dropped at a reference width from the glass bead drop opening 20 pass through the receiving plate 21 and hit the rounded portion 25c of the adjustment abutment plate 25, so that the narrow width is reached. Immediately after application of the road marking line 13, the glass beads 14 can be uniformly and narrowly dispersed.
[0017]
FIG. 6 and FIG. 10 are views showing a state when glass beads are spread widely. First, the bolts 23 and the nuts 24 are loosened and the end portions 25b of the pair of adjustment abutment plates 25 are moved away from each other to set the pair of adjustment abutment plates 25 in parallel, and then the pair of adjustment abutment plates. 25 is tightened with bolts 23 and nuts 24 and fixed to the fixing plate 22. When set in such a state, the glass beads 14 can be uniformly dispersed in the reference width immediately after application of the road marking line 13 having the reference width.
[0018]
FIG. 7 and FIG. 11 are views showing a state when glass beads are dispersed in a reference width. First, the bolts 23 and nuts 24 are loosened and the end portions 25b of the pair of adjustment abutment plates 25 are moved so as to be spaced apart from each other, and then the pair of adjustment abutment plates 25 are tightened with the bolts 23 and the nuts 24. The fixing plate 22 is fixed in accordance with the rounded portion 22b. When set in such a state, the glass beads 14 fall on the receiving plate 21, hit the rounded portion 22 b of the fixed holding plate 22 and the rounded portion 25 c of the adjustment holding plate 25, and the wide road marking line 13 Immediately after the application, the glass beads 14 can be spread uniformly and widely.
[0019]
As described above, in the application of the road marking line, when the glass beads are sprayed immediately after the marking paint is applied, two kinds of glass beads dropped from the glass bead dropping port 20 by one glass bead spraying device are used. Depending on the above road marking line width, it can be diffused and spread narrowly.
[0020]
