JPS603125Y2 - Glass bead scattering device in road paint applicator - Google Patents

Description

[Detailed Description of the Invention] This invention relates to an improvement of a glass bead dispersing device in a road paint applicator that displays various signs on the road surface.

A road paint applicator is equipped with a paint tank, glass beads tank, propane gas cylinder, etc. on a hand truck, and in addition to defining the sign surface with paint, it also sprays the glass beads to create the required reflective sign. Conventionally, as shown in FIG. 1, the mechanism for dispersing glass beads is to place a glass bead tank 1' on a dispersion frame 8' fixed to a trolley, and to The glass beads inside are designed to fall out little by little.

That is, the glass bead tank 1' is made as a constant supply hopper having a take-out roll 3' at the lower end, and a scattering frame 8' supporting this is provided with a glass bead tank 1' that receives the glass beads taken out by the take-out roll 3'. A dispersion roll 6' is mounted on a shaft to drop the material so as to have a wide width.

In the above device, the outer circumferential surface of the take-out roll 3' is formed into a rough surface made up of a large number of recesses 9', and the glass beads are inserted into the recesses 9'. Each particle is led out downward, and rubber plates or felts 4' and 5' are attached to both side edges of the discharge hole 2' at the lower end of the glass beads tank 1'. , 5' are always in pressure contact with the outer circumferential surface of the take-out roll 3' due to the elasticity of the rubber, thereby preventing glass beads other than those fitted into the recessed holes 9' from leaking out.

However, in this structure, the rotation of the roll 3' becomes heavy due to the pressure contact friction between the rubber plates 4' and 5', and this rotation is transmitted from the wheels of the handcart, which requires more effort. and a rubber plate 4'.

The glass beads tend to leak as the elasticity decreases due to wear or deterioration of the glass beads.

Furthermore, since glass beads tend to form lumps due to moisture absorption, it is necessary to heat and dry the bottom of the glass bead tank 1' from outside from time to time. There were disadvantages such as not being able to do so.

On the other hand, this idea does not use any rubber plates etc.
In order to ensure smooth unloading at all times, as shown in FIG. One edge is formed as a protruding edge 4 that covers the upper surface of the take-out roll 3, and the other edge is formed as an edge 5 along the lower half surface of the take-out roll 3.

The take-out roll 3 is fixed from a rotating shaft 10 and a fixing screw 11 as shown in FIGS. 2 and 3.

The connection between the take-out roll 3 and the rotating shaft 10 is achieved by threading the take-out roll 3 and fixing it with a fixing screw 11.

When connecting the rotating shaft 10, the fixing screw 11 must be pushed into the groove 12 provided on the rotating shaft 10, and the take-out roll 3
At the same time as rotates with the shaft 10, the take-out roll 3 can move slightly relative to the shaft 10 in the radial direction, and the gap between the edge 5 of the roll 3 and the receiver can be changed depending on the condition of the glass beads.

Note that 6 is a dispersion roll, 7 is a surrounding frame, 8 is a scattering frame, and 9 is a concave hole provided in a take-out roll, which are the same as those of the conventional apparatus described above.

With the above structure, the glass beads in the glass bead tank 1 pass through the discharge hole 2 and are rolled around the take-out roll 3, and the receiver connected to the discharge hole 2 is pressed against the edge 5 and the lower half of the take-out roll 3. It is inserted into the recessed hole 9, moves together with the take-out roll 3, and comes out from the tip of the protruding edge 4.

The take-out roll 3 has a receiver that rotates freely within the edge 5, so even if solid matter is mixed in the scattered glass beads, the take-out roll 3 and the receiver can rotate freely because the gap between the edge 5 changes. is carried out smoothly.

Road marking lines come in 10 cm, 15 cm, 20 cm, and 3 widths, so it is necessary to spray glass peas in the widths mentioned above.

Therefore, if a plurality of take-out rolls 3 are provided, they can be spread over an arbitrary width by connecting them to the rotating shaft 10 with fixing screws 11.

As described above, in this invention, both side edges 4.5 of the discharge hole 2 are brought close to the take-out roll 3, so there is no need to use a rubber plate or the like as in the conventional device, and therefore all of the above-mentioned drawbacks are eliminated. , it is possible to perform extremely efficient work.
