Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a joint material removal device, and particularly to a joint material removal device for removing the joint material adhered to the panel surface during the manufacture of tile panels.

[Prior Art] Today, tile panels are widely used, for example, on the walls of various structures such as buildings and tunnels, and have become one of the important elements that affect their appearance.

FIG. 3 shows part of the manufacturing process for such a tile panel. As is well known, the tile panel 100 is manufactured by applying mortar to the surface of the panel 10, sequentially pasting a plurality of tiles 14 on the mortar-applied surface 12 according to a predetermined pasting pattern, and then inserting a wall between each tile 14. This is done by filling the joints 16 with a joint material 18.

However, when the tile panel 100 is filled with the joint material 18, as in the tile panel 100A, the joint material 18 fills the joint 1.
6 overflows to the surface side, and the joint material 18 adheres to the surface of the tile panel in a bulging manner.

Therefore, when manufacturing the tile panel 100, after the grouting work is completed, the grout material adhering to the surface of the tile panel 100A is removed to produce a tile panel as shown in 100B. is required.

Conventionally, such surface finishing treatment of a tile panel has been performed by an operator manually removing the grout 18 from the surface of the tile panel 100.

For this reason, there have been problems in that the production efficiency of tile panels is low and the degree of surface finish varies depending on the skill level of the workers.

In particular, automation of tile panel manufacturing lines has progressed in recent years, and tile panels 100A with joints are manufactured one after another on the manufacturing line. Therefore, it is desired to develop a means for efficiently and automatically performing a surface finishing process to remove the joint material 18 adhering to the surface of the tile panel 100A and finish the tile panel as shown in 100B. It was rare.

[Problems to be solved by the invention] The present invention was devised in view of these conventional problems, and its purpose is to efficiently and automatically remove grout that has adhered to the surface of tile panels. An object of the present invention is to provide a joint material removal device that can remove joint material.

[Means for Solving the Problems] In order to achieve the above object, the present invention tilts the rotational track surface obliquely with respect to the tile panel loading path,
Moreover, it has an endless belt for removing joints that is rotated while pressing one end side to cross the surface of the tile panel being conveyed, and by rotating this endless belt, the surface of the tile panel where the joints have been removed It is characterized by removing the joint material that has adhered to the.

[Function] The present invention has the above configuration, and its function will be explained next.

In the present invention, the endless belt for removing joints is driven to rotate while pressing one end of the belt across the surface of the tile panel. Therefore, when a joint-treated tile panel is transported, the soft joint material adhering to its surface is scraped off by the endless belt, and the scraped joint material is conveyed and removed in the direction of rotation of the endless belt. be done.

In particular, according to the present invention, the endless belt
It is installed so that its rotating orbital surface is inclined obliquely to the tile panel delivery path. Therefore, by using this inclination and the tension of the belt, one end of the endless belt can always be pressed against the surface of the tile panel being conveyed with a constant biasing force. It becomes possible to more reliably remove the joint material adhering to the surface.

Further, it is preferable that the joint material removal device of the present invention is provided with means for removing joints attached to the endless belt and means for cleaning the endless belt from which the joints have been removed. Even when the panels are conveyed one after another, it is possible to reliably remove the joint material from the surface of each tile panel.

In addition, in the present invention, it is preferable to provide a container below the endless belt for collecting the joint material removed from the tile panel surface using the endless belt and the joint material removed from the endless belt. This makes it possible to reuse the collected joint material.
