Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an apparatus for attaching a connecting sheet to the surface of a set of ceramic tiles, including a plurality of tiles arranged in the same arrangement as in the construction state.

Problems to be solved by conventional technology and invention When pasting ceramic tiles on the walls or floors of a building, in order to improve construction efficiency, multiple tiles are carefully placed in the same arrangement as the construction state. A water-permeable connecting sheet such as paper is pasted on the surface of a pair of tiles using a water-soluble adhesive to join them together, and after pasting this on the construction surface, water is applied to the connecting sheet. A method is used in which the adhesive is removed from the surface of the tiles by applying it to the surface of the tiles.In order to automatically attach the connecting sheet to the surface of a set of tiles, apply the adhesive to the surface of a set of tiles using a rubber roller, brush, etc. The common method used was to apply the adhesive with a glaze and then press the adhesive. However, the surface height of ceramic tiles is not constant due to variations in the thickness of the glaze, so it is difficult to apply the adhesive sufficiently on low tiles. The problem was that it did not coat well and easily peeled off. On the other hand, in the 1980s,
Publication No. 10858 discloses a device that applies adhesive to a connecting sheet in advance and sticks it to the surface of a tile. Adhesive is applied by passing a connecting sheet between it and a pinching roller that touches this, and then the connecting sheet is placed on a rope belt and conveyed to the pasting position, and the adhesive of the application roller is applied with a pinching pressure. Since it adheres to the roller and also to the surface of the connecting sheet, it is sticky and difficult to handle, and there is room for improvement in that the connecting sheet sticks to the rope belt and is difficult to transfer to the surface of the tile.

Means for Solving the Problems The present invention provides a tile supply position where a set of tiles is arranged and supplied in a plurality of tiles, and a tile supply position where a set of tiles is cut to a certain size. Between the sheet feeding positions that feed the connecting sheets,
A rotating application roller with adhesive adhered to the outer periphery is disposed, and a suction cup is provided that reciprocates between the sheet supply position and the tile supply position through a path that contacts the application roller on the outward path, The connecting sheet at the sheet supply position is sucked by a suction cup, the adhesive is applied by pressing the connecting sheet against the application roller, and the adhesive is applied by pressing against a set of tiles at the tile supply position.

Functions and Effects of the Invention The tile connecting sheet pasting device of the present invention has the above-mentioned configuration, and the adhesive is applied to the back surface of the tile by touching the connecting sheet with the suction cup and rolling it around the application roller, and applying the adhesive to the back surface of the tile. Since the adhesive is applied by pressing it onto the surface of the connecting sheet, there is no risk of the adhesive sticking to the surface of the connecting sheet, and since the adhesive does not adhere to any components other than the application roller, it is easy to handle and ensures stable operation. There is a potential effect.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, 1 places a set of tiles a, in which a plurality of tiles a are arranged vertically and horizontally, on a mounting plate b,
A horizontal belt conveyor that intermittently transfers tiles in one direction is a belt conveyor, and a pair of air cylinders 2 are installed facing each other on both sides of the belt conveyor 1, and a mounting plate b on which tiles a are placed is placed on both sides. When it stops between the air cylinders 2, the piston rod 3 extends and fits into the notches c formed on both side edges of the mounting plate b, thereby positioning the device plate b at a certain position, and this position becomes the tile supply position. A, and a table 5 on which a connecting sheet d to be attached and connected to a set of tiles a is placed is installed at a position right next to this tile supply position A, and is wound into a roll from the side of the table 5. The leading end of the connected sheet d is transferred to the support plate 7 by the driving force of a pair of supply rollers 6, 6.
The cutter 9 is fed onto the table 5 through the space between the cutter plate 8 and the cutter plate 8, and when it protrudes a certain distance from the cutter plate 8, the cutter 9 swings about the shaft 9a as a fulcrum due to the extension of the air cylinder 10 and slides on the front edge of the cutter plate 8. By doing so, the connected sheet d is cut into a certain size and fed onto the table 5, and the top of the table 5 is the sheet feeding position B.

Between the above-mentioned tile supply position A and sheet supply position B, an adhesive having a length approximately equal to the width of the connecting sheet d and having several circumferential grooves 13 formed at intervals on the outer peripheral surface is applied. The application roller 12 for use in the application is freely rotatable in a position perpendicular to the direction connecting the tile supply position A and the sheet supply position B, and in a position where the upper surface slightly protrudes from the upper surface of the table 5. The upper surface is rotated at a constant circumferential speed in the direction of moving toward the tile supply position A by the source, and the above-mentioned circumferential groove 1 of the applicator roller 12 is formed on the outer peripheral surface diagonally below the applicator roller 12.
The auxiliary roller 14 has a protruding collar 15 that fits into the
The auxiliary roller 14 is freely rotatable in parallel with the coating roller 12 and rotates in the opposite direction to the coating roller 12 by meshing with gears (not shown). The axis position can be adjusted to move so as to adjust the corresponding gap between the surfaces, and the adhesive e is applied to a position corresponding to the valley formed between the applicator roller 12 and the auxiliary roller 14 toward the valley. A discharge nozzle 17 is provided, and this nozzle 17
Then, a certain amount of adhesive e is pumped using a pressure pump that pressurizes and delivers the adhesive e, or a gear pump.
At the same time, several guide rods 19 facing toward the sheet supply position B are attached to a bracket 20 that is freely swingable on the side of the tile supply position A of the application roller 12. It is mounted in a cantilevered manner, and the tip of each guide rod 19 is hidden and fitted into the above-mentioned circumferential groove 13 on the upper surface of the application roller 12, and is supported in a horizontal position.

Additionally, above the aisle supply position A and the sheet supply position B, a horizontal air cylinder 21 expands and contracts to move the air between the tile supply position A and the sheet supply position B along a pair of horizontal guide bars 22, 22. A moving body 23 that reciprocates is installed, and a number of holes 28 are formed through the lower surface of the tip of the piston rod 26 of an air cylinder 25 that is attached downward to the moving body 23 and have a size approximately equal to that of one connecting sheet d. A suction box 27 is attached and connected to a negative pressure source (not shown), and a rubber suction cup 29 is attached to the bottom surface of the suction box 27, which has a number of suction holes 30 aligned with the holes 28 described above. It is being

Next, the operation of this embodiment will be explained.

From the nozzle 17 to the application roller 12 and the auxiliary roller 1
Adhesive e is discharged into the valley of 4, and the application roller 1
2 rotates in a direction in which the upper surface moves toward the tile supply position A side, and the auxiliary roller 14 rotates in the opposite direction accordingly, the adhesive e is pushed out through the gap between both rollers 12 and 14, and The coating roller 12 rotates with the adhesive e having a thickness corresponding to the size of the gap adhered to the outer peripheral surface of the coating roller 12, and when the movable body 23 returns to above the sheet supply position B, the suction cup When the air cylinder 25 for lifting and lowering is extended, the suction cup 29 is pressed against the surface of one connecting sheet d supplied on the table 5 and the connecting sheet d is attracted, and the air cylinder 25 for lifting and lowering the suction cup is slightly contracted. After lifting the connecting sheet d to the upper surface of the application roller 12, the air cylinder 21 for driving the movable body is extended to move the movable body 2.
3 to the tile supply position A side at the same speed as the circumferential speed of the coating roller 12, on the way, the back surface of the connecting sheet d gradually touches the top surface of the coating roller 12 rotating at the same speed from the tip side. The adhesive e that has been pressed and adhered to the application roller 12 is applied to the back side of the connecting sheet d, passes over the guide rod 19 and moves directly above the tile supply position A, and then the air cylinder 25 for raising and lowering the suction cup is moved. When stretched, the suction cup 29 is elastically contracted on the surface of a set of tiles a supplied to the tile supply position A, and the connecting sheet d
is pressed, and the connecting sheet d is pasted on the surface of the tile a. Then, when the negative pressure in the suction box 27 is released and the air cylinder 25 for raising and lowering the suction cup is contracted, the suction cup 29 is separated from the connecting sheet d. After the piston rod 3 of the air cylinder 2 for positioning the placement plate b on which the tile a is placed contracts, the belt conveyor 1 runs and connects the connecting sheet d.
At the same time, one set of tiles a to which the Supply position B
After that, the above operation is repeated, and the connecting sheets d are successively pasted one by one on the surfaces of the set of tiles a supplied to the tile supply position A.

In this embodiment, the corresponding gap between the applicator roller 12 and the auxiliary roller 14 is adjustable, so if the corresponding gap is widened, the adhesive e can be thickened and adhered to the outer peripheral surface of the applicator roller 12. And, conversely,
By narrowing the corresponding gap, it is possible to adhere with a thinner thickness, and since the horizontal guide rod 19 is disposed on the same surface as the upper surface of the application roller 12 on the side of the tile supply position A of the application roller 12, the adhesion can be made thinner. The connected sheet d coated with the agent e moves from the upper surface of the application roller 12 directly over the guide rod 19, and the connected sheet d
Sticking to the application roller 12 and getting caught up in the application roller 12 is reliably avoided.

Further, an optical or ultrasonic sensor is provided opposite to the valley between the application roller 12 and the auxiliary roller 14 to detect the height of the adhesive e supplied to the valley and the extent to which it protrudes from the edges of the rollers 12 and 14. The pressure of the pressure pump that pumps the adhesive e or the rotation speed of the gear pump can be increased or decreased based on the signal from the sensor.
It becomes possible to always supply a constant amount of energy without excess or deficiency.
