Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is characterized in that a plurality of sheets arranged in the same arrangement as in the construction state
This invention relates to a device for attaching a connecting sheet to the surface of a set of ceramic tiles.

Problems to be Solved by the Prior Art and the Invention When pasting ceramic tiles on the walls or floors of a building, in order to improve construction efficiency, multiple tiles are arranged 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 tile by applying it to the surface of the tile.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, because the surface height of ceramic tiles is not constant due to variations in the thickness of the glaze, it is difficult to apply the adhesive sufficiently on low tiles. However, it had the drawback of being easy to peel off. On the other hand, Jikko Sho 60-1
Publication No. 0858 discloses an apparatus in which adhesive is applied to a connecting sheet in advance and the adhesive is applied 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. There was room for improvement in that it adhered to the rollers and also to the surface of the connecting sheet, making it sticky and difficult to handle.Also, the connecting sheet stuck to the rope belt, making it difficult to transfer it to the surface of the tiles. .

Means for Solving the Problems The present invention aims to solve these problems by providing a tile supply position that supplies a set of tiles in a row, and a tile supply position that supplies a set of tiles that are cut to a certain size. A rotating application roller with adhesive adhered to its outer periphery is arranged between the sheet supply positions that supply the connected sheets, and the application roller contacts the application roller on the outward path between the sheet supply position and the tile supply position. A suction cup is provided that moves back and forth through the path.

The suction cup sucks the connected sheet at the sheet supply position, the connected sheet is pressed against the application roller to apply an adhesive, and the adhesive is applied by pressing against a set of tiles at the tile supply position.

Effects and Effects of the Invention The tile connecting sheet pasting device of the present invention has the above configuration,
While holding the connecting sheet with a suction cup, apply the adhesive to the back side by rolling it over the application roller, and then press it against the surface of the tile to stick it, so the adhesive sticks to the surface of the connecting sheet. Furthermore, since the adhesive does not adhere to components other than the application roller, it is easy to handle and has the effect of ensuring stable operation.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2.

In the figure, 1 is a set of tiles A, in which a plurality of tiles A are arranged vertically and horizontally, placed on a mounting plate.

It is a horizontal belt conveyor that intermittently transfers tiles in one direction, and a pair of air cylinders 2 are installed facing each other on both sides of the belt conveyor l, and a mounting plate on which tiles a are placed is provided with both air cylinders. When it stops between the cylinders 2, the piston rod 3 extends and fits into the notches C formed on both sides of the mounting plate, so that the mounting plate is positioned at a certain position, and this position is used for supplying tiles. A table 5 on which a connecting sheet d to be pasted and connected to a set of tiles a is placed is installed right next to this tile supply position A, and from the side of the table 5, the connecting sheet d is rolled up into a roll. A pair of supply rollers 6.6
The table 5 passes between the support plate 7 and the cutter plate 8 with the driving force of
When the cutter 9 is fed upward and protrudes a certain distance from the cutter plate 8, the cutter 9 swings about the shaft 9a as a fulcrum due to the expansion of the air cylinder IO and slides on the front edge of the cutter plate 8, so that the connected sheet d is kept constant. The sheet is cut into a size of 1, and is supplied onto a table 5, and the sheet supply position B is on the table 5.

Between the above tile supply position A and sheet supply position [B,
An application roller 12 for applying adhesive, which has a length approximately equal to the width of the connecting sheet d and has several circumferential grooves 13 formed at intervals on the outer circumferential surface, is located at the tile supply position A and the sheet supply position B.
The device is freely rotatable in a position perpendicular to the direction in which the table 5 is connected, and the top surface slightly protrudes from the top surface of the table 5, and the top surface is moved in a constant direction toward the tile supply position A by a drive source (not shown). It rotates at a circumferential speed and is positioned diagonally below this coating roller 12.

An auxiliary roller 14 having a protruding collar 15 on its outer circumferential surface that fits into the circumferential groove 13 of the applicator roller 12 is freely rotatable in a position parallel to the applicator roller 12, and is connected to the applicator roller 12 by meshing with gears (not shown). The auxiliary roller 14 is designed to rotate in the opposite direction, and its axial center position can be adjusted so as to adjust the corresponding gap between its outer peripheral surface and the outer peripheral surface of the application roller 12. 12
A nozzle 17 for discharging the adhesive e toward the valley is arranged at a position corresponding to the valley formed between the auxiliary roller 14 and the auxiliary roller 14. A fixed amount of adhesive e is continuously supplied by a pressurizing pump or a gear pump, and the sheet is placed on a bracket 20 that is freely swingable on the side of the tile supply position A of the application roller 12. Several guide rods 19 facing the supply position B side are attached in a cantilevered manner, and the tip of each guide rod 19 is hidden and fitted in the above-mentioned circumferential groove 13 on the upper surface of the application roller 12, so that it is horizontal. Supported by posture.

Moreover, above the tile supply position A and the sheet supply position B, the space between the upper part of the tile supply position A and the sheet supply position B is provided along a pair of horizontal guide bars 22 and 22 by the expansion and contraction of the horizontal air cylinder 21. A movable body 23 that reciprocates is installed, and a number of holes 28 are inserted through the lower surface of the piston rod 26 of an air cylinder 25 that is attached downward to the movable body 23 and have a size approximately equal to that of one connecting sheet d. A suction box 27 is attached to the suction box 27, which is connected to a negative pressure source (not shown).
A rubber suction cup 2 with a large number of transparent suction holes 30 aligned with the
9 is attached.

Next, the operation of this embodiment will be explained.

Adhesive e is discharged from the nozzle 17 into the gap between the application roller 12 and the auxiliary roller 14, and the application roller 12 rotates in a direction in which its upper surface moves toward the tile supply position A, and as a result, the auxiliary roller 14 rotates in the opposite direction. When the application roller 12 rotates to 12 rotates, and when the movable body 23 returns to above the sheet supply position B and the air cylinder 25 for raising and lowering the suction cup is extended, the suction cup 29 moves one connected sheet supplied onto the table 5. The connecting sheet d is pressed against the surface of d and is attracted, and the air cylinder 25 for raising and lowering the suction cup is slightly contracted to lift the connecting sheet d to the upper surface of the application roller 12, and then the air cylinder 21 for driving the moving body is moved. When the movable body 23 is moved toward the tile supply position A side at the same speed as the circumferential speed of the application roller 12, the connecting sheet d
The back surface of the sheet is pressed against the top surface of the coating roller 12 which is rotating at the same speed gradually from the tip side, and the adhesive e adhering to the coating roller 12 is applied to the back surface of the connecting sheet d and passes over the guide rod 19. When the suction cup 29 is moved to above the tile supply position A and then the air cylinder 25 for raising and lowering the suction cup is extended, the suction cup 29 is elastically connected to the surface of the set of tiles a supplied to the tile supply position A. The sheet d is pressed and the connecting sheet d is pasted on the surface of the tile a. Then, when the negative pressure of 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 attached to the connecting sheet d. After the piston rod 3 of the air cylinder 2 for positioning the mounting plate on which the tile a is placed contracts, the belt conveyor 1 runs and the connecting sheet d is moved upward. One set of tiles a with
The set of tiles a is supplied to the tile supply position A, and during this time, the movable body 23 returns to above the sheet supply position MB due to contraction of the air cylinder 21 for driving the movable body, and the above operation is repeated thereafter. , the connecting sheets d are sequentially pasted one by one on the surfaces of the set of tiles a supplied to the tile supply position A.

Note that in this embodiment, the application roller 12 and the auxiliary roller 14 are
Since the corresponding gap is adjustable, if the corresponding gap is widened, the adhesive e will be thicker and adhered to the outer peripheral surface of the application roller 12, and conversely, if the corresponding gap is narrowed, a thinner layer will be applied. Moreover, since the horizontal guide rod 19 is disposed on the same surface as the upper surface of the coating roller 12 on the side of the tile supply position A of the coating roller 12, the connecting sheet d coated with the adhesive e moves directly from the upper surface of the application roller 12 through the guide rod 19, and the connected sheet d moves from the upper surface of the application roller 12.
2. Sticking to it and getting caught in it is definitely avoided.

Also, the height of the adhesive e supplied to the valley and the roller 12.1 facing the valley between the applicator roller 12 and the auxiliary roller 14 are
An optical or ultrasonic sensor is installed to detect the degree of protrusion from the edge of 4, and the signal from the sensor controls the increase or decrease of the pressure of the pressure pump that pumps the adhesive e or the rotation speed of the gear pump. By doing so, it becomes possible to always supply a constant amount of adhesive e without excess or deficiency.
