A resin mortar 54 is applied to the surface of the panel 53, and a tile (not shown) is attached thereon. Conventionally, the coating operation of the mortar 54 is manually performed as follows. That is, an operator applies the mortar 54 to the surface of the panel 53 with the gold iron 55, and the mortar 54 is evenly distributed over the entire surface of the panel with the gold iron 55. After that, the mortar 54 is smoothed and smoothed so that the thickness of the mortar 54 becomes about 3 mm.

[0003]

[Problems to be solved by the device]

 As described above, conventionally, since the mortar 54 is manually applied by the worker, there is a problem that the mortar 54 has a specific efficiency and the thickness of the mortar 54 varies depending on the worker. Therefore, mechanization of the coating work is desired, but it is difficult to achieve the mechanization because it is necessary to uniformly coat the wide panel surface with a thickness of about 3 mm.

An object of the present invention is to provide a mortar applicator that can evenly apply mortar to a panel surface.

[0005]

[Means for Solving the Problems]

 The mortar applicator according to the present invention is provided with a traveling body that travels on a pedestal along the upper side of a panel placed on a panel support, and the traveling body is provided with a mortar filler and a leveling device. The mortar filler has a plurality of mortar discharge nozzles arranged in a direction orthogonal to the traveling direction of the traveling body.

[0006]

[Action]

 The mortar filler discharges mortar from each mortar discharge nozzle while moving above the panel as the traveling body travels, and applies mortar onto the panel. The applied mortar is scraped and leveled by a leveling device as the running body travels so that each part has a uniform thickness.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. The mortar coating device 1 is mainly composed of a panel support base 2, a pedestal 3, a traveling body 6 equipped with a mortar filler 4 and a leveling device 5. A conveyor 8 is installed to transport the panel 7 through the lower part of the gantry 3. The panel 7 is made by assembling a steel frame 7b to a plurality of face members 7a made of an extruded plate or the like. The conveyor 8 is a chain conveyor having two chains 8a as shown in FIG.

The panel support 2 has three independent elevating frames 9 parallel to the conveyor 8, and each elevating frame 9 is moved in and out of the conveyor surface of the conveyor 8 by three elevating cylinders 12. It is driven up and down to the height. In addition, each elevating frame 9 is supported by a fixed base so as to be able to ascend and descend via a guide rod (not shown) suspended from the lower surface. Further, mortar trays 23 (FIG. 1) are arranged on the floor surface at the front and rear ends of the panel 7 placed on the panel support base 2.

The pedestal 3 is provided with a pair of parallel rails 13 having an interval wider than the width of the panel 7 in an upper position in parallel with the conveyor 8, and the traveling body 6 has traveling wheels 14 at both ends on both rails 13. It is installed so that it can run freely. The traveling body 6 is driven by a self-propelled motor (not shown) that drives traveling wheels 14, or is driven by an endless chain or the like provided along the rail 13.

The mortar filler 4 comprises a groove-shaped bucket 15 having a length along the entire width of the panel 7 and a plurality of downward-facing mortar discharge nozzles 16 provided at an appropriate pitch. Installed on. The leveling device 5 is provided in a pair before and after the mortar filler 4, and is composed of a leveling plate 22 extending in a direction orthogonal to the traveling direction, and an elevating cylinder 17 for moving the leveling plate 22 up and down.

FIG. 4 is an enlarged sectional view of the mortar filler 4. Inside the bucket 15, a mortar adjusting valve 18 is provided for each nozzle 16. The mortar adjusting valve 18 has a valve body 18a that is in contact with a valve seat 16a at the upper edge of the nozzle 16, and the valve body 18a is integrally provided on an elevating rod 18b that penetrates the bucket lid 15a in a vertically movable manner. There is. The upper end flange 18c of the elevating rod 18b is pressed against the cam 20 by the urging force of the spring member 19, and is moved up and down as the cam 20 rotates. By this ascending / descending, the valve body 18a ascends / descends by the lift H, and adjusts the flow of the mortar 21 from inside the bucket 15 to the nozzle 16. The cam 20 of each mortar regulating valve 18 can be individually driven by an actuator (not shown) such as a motor or an air cylinder. The lowering part 22a of the leveling device 22 of the leveling device 5 is inclined in a direction away from the mortar filler 4, and the leading end 22b of the lower end 22a is formed in a comb tooth shape.

The mortar application operation with the above configuration will be described. When the panel 7 conveyed on the conveyor 8 moves to a predetermined position in the mortar coating apparatus 1, each ascending / descending frame 9 of the panel support base 2 is raised to lift the panel 7 and hold the panel upper surface at a predetermined level. ..

In this state, the mortar adjusting valve 18 of each nozzle 16 of the mortar filler 4 is opened, and while the traveling body 6 is traveling, the mortar 21 is discharged onto the panel 7 as shown in FIG. The mortar 21 discharged in a raised state on the panel 7 is leveled with the running of the running body 6 by the leveling plate 22 located behind the mortar filler 4 in the running direction, and becomes a flat mortar coating layer 21a. Such a coating operation is repeated several times by the reciprocation of the traveling body 6, and the mortar 21 is coated repeatedly, so that the mortar coating layer 21a on the panel 7 has a predetermined thickness, for example, about 3 mm. ..

The above-mentioned mortar discharge and leveling operations are performed in both the forward stroke and the return stroke of the traveling body 6. When changing the traveling direction, the leveling plate 22, which is located in front of the traveling direction, is released upward by the elevating cylinder 17, and the leveling plate 22 at the rear is lowered. Excess mortar 21 generated by the leveling work by the leveling plate 22 is dropped at the front and rear ends of the panel 7 and received by the mortar tray 23. When the mortar coating operation is completed in this way, the panel support base 2 is lowered to lower the panel 7 onto the conveyor 8 and the conveyor 8 conveys it to the next tile attaching step.

According to the mortar coating apparatus 1, the mortar coating and the leveling work can be automatically performed on the panel surface as described above, and the work can be saved. In this case, since a large number of mortar discharge nozzles 16 are provided side by side and the discharged mortar 21 is leveled by the leveling plate 22, the mortar coating layer 21a can have a uniform thickness. Further, by repeating the coating operation, it is possible to coat to a desired thickness. As a result, the quality of subsequent tiles can be improved.

Since each mortar discharge nozzle 16 is provided with a mortar adjusting valve 18 separately, it is possible to correspond to a panel 7 of various widths by opening only the necessary valve 18 and also to a panel with an opening. This mortar coating device 1 can be used.

FIG. 7 shows an example of a tiling line in which the mortar coating apparatus 1 is installed. The moving traverser 24, the mortar applicator 1 and the tiler 25 are installed side by side, and the conveyor 8 and another conveyor 26 are installed so that the panel 7 can be continuously transferred thereto. There is. The moving traverser 24 is a device that conveys the panel 7 on which the frame 7b (FIG. 1) has been assembled in the previous process to the conveyor 8.

5 and 6 show an example of the tile applying device 25. In this tile applying device 25, a tile set base 28 is provided in front of the panel stop position of the positioning conveyor 27, and a traveling body 29 that travels from the tile set base 28 to above the panel 7 is provided on the base 30. A plurality of suction pads 32 and a plurality of vibrators 33 are provided on an elevating body 31 which is suspended from a traveling body 29 so as to be able to elevate. The tile set table 28 is tiltable.

In the tile applying device 25, the worker 34 arranges the tiles 44 (FIG. 6) on the tile set table 28 by the traveling body 29 with the suction pads 32 to adsorb the tiles 44 to a desired position on the panel 7. Then, the tiles are attached by pressing the tiles 44 against the mortar on the panel surface. At the time of pressing, the tile is vibrated by the vibrator 33 to improve the adhesion of mortar.
