Description

[Detailed description of the invention] [Industrial application field] This invention relates to a Keren device for concrete adhering matter, and more specifically, a Keren device for removing adhering concrete and paint on a scaffold plate or a building frame used for construction of a temporary scaffold. Related to the device.

[Conventional technology]

Concrete and paint adhere to the scaffolds and building frames used at the construction site, so that it is necessary to remove them when using them next time.

By the way, the scaffolding frame has a structure in which pipes are assembled in a gate shape or a torii shape, and the scaffolding plate is formed by bending a metal plate. Therefore, both structures are completely different.

Performing the manual removal of the adhering matter to the building frame or the scaffold as described above takes time and labor and increases the operation cost. It is considered.

However, in the conventional Keren device, since the structures of the building frame and the scaffolding board are completely different, the Keren device for the building frame and the Keren device for the scaffolding board have been dedicated independent devices respectively.

In addition, concrete and resin paint adhered to building frames and scaffolds have different adhesive strengths, and therefore, the peeling means for both are also different. Specifically, concrete is peeled off by impact, and paint etc. It is efficient to remove by scraping.

[Problems to be solved by the invention]

As described above, if the Keren devices for the building frame and the scaffold are separate, there is a problem that the equipment cost is high and a wide installation space is required.

In order to solve the above-mentioned problems, the present invention can continuously perform the striking and scraping operations, and can perform the construction frame and the scaffold plate with a single structure, thereby reducing equipment costs and installation space. It is an object of the present invention to provide a keren device for concrete deposits that can be reduced.

[Means for solving the problem]

In order to solve the above-mentioned problems, the present invention provides a dresser mechanism in which a plurality of keren members are arranged side by side around a rotating shaft on a work transfer line that supports and sends a work, and the keren member is a work surface of the work. And a rotating shaft that is arranged so as to be struck against the workpiece, and the dresser mechanism is arranged parallel to the work surface and perpendicular to the traveling direction,
Around the rotary shaft, a plurality of flexible shafts are provided at equal intervals at positions on the same circumference centered on the rotary shaft, and a plurality of shafts that rotate integrally with the rotary shaft are provided. A flexible member is directed backward in the rotational direction, and the swing around the shaft is limited to a certain range. In this case, a configuration is adopted in which it is mounted in a state where it is mounted.

[Action]

When the work is moved along the transport line while each dresser mechanism is rotated, the work comes into contact with the keren member and the flexible scraping member of the rotating dresser mechanism, thereby adhering concrete, paint, etc. Is scraped.

The dresser mechanism uses two types, one in which a number of keren members are arranged around the rotation axis, and the other in which a number of flexible scraping members protrude from the end surface of the rotation member. The mechanism responds to the work of concrete by hitting the work, and the latter dresser mechanism is effective for scraping of resin etc. by scraping, so that the work can be done on the scaffold plate and the building frame in any case .

It strikes on the tip side of 35 and peels off the adhering concrete.

Each scraping member 35 collides with the surface of the work A by centrifugal force due to rotation, applies a striking force, and exhibits an excellent Keren effect, and since each scraping member 35 is in an independent state in which many pieces are arranged in parallel, Concrete can be removed even when the upper surface of the work is curved.

In the second and third dresser mechanisms 3 and 4, the chip 57 of the scraping member 55 rotating in a plane is in sliding contact with the work A, and peels off paint, resin and the like adhering to the work A.

Since each scraping member 55 is formed in a flexible shaft shape and is rotated around the axis of the rotating member 54, as shown in FIG. When the tip 57 abuts on the pipe, the tip 57 slides in the axial direction of the pipe when going over the pipe.

As described above, the first dresser mechanism 2 has a structure in which a large number of parallel scraping members 35 are rotated about the horizontal rotating shaft 23, so that the keren on the flat surface can be performed by the impact force, and thus Can be effectively removed.

On the other hand, the second and third dresser mechanisms 3, 4
Since the scraping member 55 is rotated in a plane, the scraping of resin or the like by sliding is mainly performed, so that the scraping of the work constituted by the pipe can be effectively performed, and the resin or the like adhered to the scaffolding frame. Suitable for removal of

As described above, since the first dresser mechanism 2 and the second and third dresser mechanisms 3 and 4 have different Keren functions for a flat surface and a curved surface, the Keren work can be performed on both the scaffold plate and the building frame. Can be performed, and both concrete and resin can be removed.

It should be noted that keren on the building frame is turned upside down and then turned upside down to make up the other side.
