  As described above, the apparatuses disclosed in Patent Documents 1 to 4 send out the connecting paper 101 or the connecting sheet 104 in which the adhesive is applied to the upper surface of the tile 100 set on the pallet 105 as described above, and the roller 106 or the like. To press.

  On the other hand, the tile unit shown in FIG. 10 responds to the recent demands of users, and changes the protruding amount of the tile from the wall surface to improve the design. Thus, when one tile unit is comprised with the tile from which thickness differs, a connection sheet cannot be stuck on the upper surface of a tile like FIG. Therefore, about the wall surface excellent in the designability in this way, tiles must be individually attached to the wall surface, which is inferior in work efficiency.

In order to solve the above-described problems, a tile processing machine according to the present invention includes a pallet that allows ventilation in the vertical direction, and a line that conveys the pallet. There is provided a connecting sheet supply unit that is set on the upper surface, and a tile transfer unit that transfers a plurality of tiles in a predetermined arrangement on the upper surface of the connecting sheet on the downstream side of the connecting sheet supply unit. The drying means which dries the adhesive agent of the connection sheet adhering to the lower surface of the tile from the lower side of the pallet is provided on the downstream side of the pallet.
In this way, since the connecting sheet is put on the lower surface of the tile and bonded, the tile unit can be configured even with a plurality of tiles having different thicknesses.

  By constructing the pallet transport line with a pair of endless chains that circulate, the return path (lower stage) can be used for drying tiles, and the overall length of the apparatus can be shortened.

  In addition, when the transport line is a circulation line, a discharge unit for the tile unit can be provided upstream of the connecting sheet supply unit, and a blower for drying the tiles can be further provided upstream of the discharge unit. The degree increases.

Any one of the connection sheet supply units may be selectively usable.

  As the configuration of the pallet, a structure in which an expanded metal, a punching metal, a wire mesh, or the like is attached to a frame body can be considered.

  According to the present invention, since the connecting sheet is put on the lower surface of the tile and bonded, the tile unit can be configured even with a plurality of tiles having different thicknesses. In addition, since the adhesive applied to the connecting sheet is dried from the bottom using a pallet that allows ventilation in the vertical direction, the adhesive can be dried in a short time.

  Therefore, it is not necessary to stock a part of the factory for a long time (several days) until drying, and the stock space becomes unnecessary.
