Description

[Detailed description of the invention] [Industrial field of application] The present invention is a surface finishing device for tile panels, especially in the final stage of tile panel manufacturing, which removes joint material adhering to the panel surface and prepares the surface of the joint area. The present invention relates to a surface finishing device for tile panels that performs joint finishing.

[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 determine the appearance of the structures.

FIGS. 5a to 5c show part of the manufacturing process for such a tile panel. As is well known,
To manufacture a tile panel, mortar is applied to the surface of the panel 10, a plurality of tiles 14 are sequentially pasted on this mortar layer 12 according to a predetermined pasting pattern, and then the joints 16 between each tile 14 are pasted.
This is done by filling the joint material 18.

However, when performing the joint filling work of filling the tile panel with the joint material 18, 1
Like the tile panel shown with 00A, the joint material 18
The joint material 18a overflows from the joint 16 to the surface side, and the joint material 18a adheres to the surface of the tile panel in a raised state.

Therefore, when manufacturing tile panels, the tile panel 1 is
From 00A, the joint material 18a attached to the surface is roughly removed to form a tile panel 100B (rough finishing). Finally, a small amount of joint material 18a remained on the surface of the tile panel 100B.
At the same time, the surface of the joint material 18 of the joint 16 is adjusted to a predetermined depth to form a so-called painted joint.
It is necessary to finish the tile panel as shown by 0C (final finishing).

Conventionally, such surface finishing treatment of a tile panel has been carried out by an operator manually removing the joint material 18a from the surface of the tile panel 100 using a roller or a rotating brush.

This reduces the production efficiency of tile panels,
Moreover, there is a problem in that the degree of surface finish varies depending on the skill level of the operator.

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 has been desired to develop a means for efficiently and automatically performing a surface finishing process to remove the joint material 18a attached to the surface of such a tile panel 100A and finish the tile panel as shown in 100C.

[Problems to be solved by the invention] The present invention was developed in view of the above-mentioned conventional problems, and its purpose is to completely remove the grout that has adhered to the surface of the tile panel and to solve the problem. To provide a tile panel surface finishing device that can efficiently and automatically finish the surface of joint parts.

[Means for Solving the Problems] In order to achieve the above object, the present invention is provided with a device that is installed so as to intersect with the conveyance path of the tile panel, and is rotated with its lower end facing the surface of the tile panel. an endless belt for removing joint material; a pressing member installed to intersect with the conveying route of the tile panel and pressing the endless belt against the surface of the tile panel; and a cleaning means for cleaning the endless belt. The configuration has the following.

[Function] In the present invention, the endless belt for removing joint material is rotated with its lower end surface being pressed against the surface of the tile panel by a pressing member with an appropriate pressing force. Therefore, when a joint-treated tile panel is transported, the soft joint material adhering to its surface is wiped off by the endless belt, and the wiped joint material adheres to the surface of the endless belt. Furthermore, the grout adhered to the surface of the endless belt is removed by the cleaning means, so the endless belt in contact with the tile panel is always in a clean state, ensuring removal of the grout from the surface of the tile panel. Moreover, it can be carried out efficiently.

In addition, the endless belt can remove the joint material that has adhered to the surface of the tile panel as described above, and can scrape off the surface of the joint material filled in the joints with an appropriate pressing force, so that it can deepen the joints. It is possible to perform so-called joint finishing, which adjusts the thickness to a predetermined depth.

Note that the surface finishing device of the present invention is applied in the final finishing performed after the rough finishing treatment shown in FIG. 5b.

In particular, in the present invention, the endless belt for removing joint material is arranged so as to intersect with the transport path of the tile panel. Therefore, the rotational driving force of the endless belt acts on the surface of the tile panel in two parts: a component force in the direction opposite to the conveyance direction of the tile panel, and a component force in the direction perpendicular to the conveyance direction. I can do it. As a result, a two-dimensional frictional force can always be applied uniformly to the surface of the tile panel, which makes it possible to reliably remove the grout that has adhered to the surface of the tile panel, and to The surface treatment of the joint portions extending in multiple directions as described above can be uniformly performed.

The pressing force and frictional force of the endless belt against the tile panel surface are the pressing force of the presser member,
By adjusting the rotation speed of the endless belt and the conveyance speed of the tile panel, it can be set within an appropriate range, and by doing so, the wiping force of the endless belt and the depth of the joint can be set to the desired level. It can be done.

In addition, the inclination angle of the endless belt with respect to the tile panel conveyance direction is not particularly limited, and is selected depending on the tile panel conveyance speed, the tile panel pasting pattern, etc., but is usually preferably 30 to 60 degrees.
selected from a range of degrees.

The endless belt in this invention is made of a material that is flexible and has a porous structure, such as sponge rubber, at least on the wiping surface that comes into contact with the tile panel, so that it has excellent durability and can effectively wipe away the joint material. is preferred.
