The air operation box 57, which is suctioning, also functions as a negative pressure breaking device (also referred to as a vacuum breaking device) when the suction force is released.

(Consideration of alternative aspects) Various embodiments are possible for the equipment of the present invention.

For example, the tile conveyance path 8 on which the equipment of the present invention is installed is not limited to one that is continuous in one section, but may be one that is distributed and installed in each tile conveyance path that spans multiple sections.
Further, the structure of the tile conveyance path is not limited at all, and may be, for example, a roller conveyor. Therefore, the requirements for each of the foods constituting the equipment of the present invention will be discussed separately below.

(1) Regarding tiles: Tiles may be for interior or exterior use, and the number of tiles connected is arbitrary. Of course, the shape and number of the connecting paper are not limited in any way, and the position at which the connecting paper is attached is also determined when the connecting tile groups a and b (see Figures 6 and 7) are used in the manufacture of tile units for the tile tip method. When used as a preparation material in the step, it is the back side (sole forming side), and the connected tile groups a and b
When used as a unit tile, it is the front side.

(2) Regarding the joint correction device 15, if the desired joint correction accuracy of the aligned tile group is only rough, there is no need to go to the trouble of operating the vertical joint correction device 16, and the correction can be performed only by the horizontal joint correction device 24. I can do it. That is, if the horizontal joint correction device 24 is operated while the tile conveyance path 8 remains in operation, each tile in the pallet 9 receives a diagonally backward pulling force, and the vertical joints and horizontal joints are corrected. That will happen. On the other hand, if strict joint correction accuracy is desired, a vertical joint correction tool 19 may also be installed downstream of the horizontal joint correction device 24, as shown in FIG. , even after correcting the horizontal joints of a group of aligned tiles, the vertical joints can be corrected again.
It becomes even more effective. Furthermore, since the tiles transported on the tile transport path 8 are not limited to being loaded into the pallet 9, in such a case, the configuration of the joint correction device 15 may be changed as appropriate. be done.

(3) Regarding the adhesive dropping device 30, any device that can quantitatively feed the adhesive may be used.
All (not limited)

(4) Regarding the connecting paper supply device 45, as shown in FIG. 1, a stock case group 47 for connecting papers
If a spare stock case group 63 is provided next to the tile transport path 8 so as to be parallel to the transport direction of the tile transport path 8, it is possible to load connecting paper into the other stock case group 63 while one stock case group 47 is in use. Easy to prepare and very convenient. In this case, it is preferable that the trolley 64 on which the two stock case groups 47, 63 are mounted is moved back and forth on a track 65 laid on the floor within the factory.

(5) Concerning the connected paper pressing device: Needless to say, this connected paper pressing device may be configured as a separate device from the continuous paper supply device 45.

In this way, the detailed configuration and the shape of each part of the equipment of the present invention can be changed as appropriate depending on the embodiment.

"Effects of the Invention" As is clear from the above explanation, according to the connected tile group manufacturing equipment according to the present invention, the problems associated with conventional adhesive application devices are completely eliminated by the development of a new adhesive dripping device. As a result, the distribution efficiency of the entire connected tile group production facility has been greatly improved. Moreover, when the adhesive dripping device according to the equipment of the present invention is compared with the conventional adhesive coating device, it can be seen that it has many unique advantages. Since the adhesive is supplied to the upward facing surface without contact, the alignment of each tile transported on the tile transport path is not disturbed, and there is also a storage tank that stores the adhesive. is set in an inverted position, and its outlet is inserted into a manifold so that the adhesive inside is completely isolated from the outside air, so the adhesive will harden before it is applied to the tiles. This adhesive dripping device is superior to the adhesive applicator 4 shown in FIG. This is an epoch-making device that is superior to the adhesive applicator 10 shown in FIGS. 9 and 10 in that it requires an extremely short time.
