Description

A tile and stone paving device and paving method

Technical Field

The invention relates to the technical field of floor tile paving operations, and in particular to a tile and stone paving device and a paving method.

Background Art

The existing adhesive laying process for automated laying of ceramic tiles and stones (hereinafter referred to as floor tiles) is as follows: the tile adhesive is pumped out by a screw pump, enters the material trough through a feed pipe, and then the equipment moves backward. The adhesive is scraped out by the scraping teeth of the material trough and remains on the work surface, forming an adhesive layer with scraping teeth on the upper part of the entire surface. Subsequently, the robotic arm places the floor tiles on the adhesive layer and presses down to vibrate to complete the laying process.

Since the adhesive is a fluid and needs to be evenly laid within a width range of 0.6 to 1.2 meters, the current adhesive height control accuracy is within 3 mm, which leads to two problems in the existing automated adhesive laying:

When the adhesive height is at the lower limit of the control accuracy, the robot arm presses down and vibrates until the back of the floor tile is full of slurry. At this time, the finished height of the floor tile will be one to two millimeters lower than the preset height. If it is vibrated to the full slurry state at the upper limit, it will be one to two millimeters higher than the preset height. The national standard for floor tile laying stipulates that the height difference of the tile edge cannot be greater than 0.5 mm, and the height difference within 2 meters cannot be greater than 3 mm. This results in the need for the tiler to make a fine adjustment after our automated floor tile laying, which will greatly reduce the work efficiency.

If we control the mechanical arm to press down and vibrate to the predetermined height of the finished floor tile surface, if the adhesive height is at the lower limit of the control accuracy, the floor tile cannot be fully slurried on the back, and the gap between the back of the tile and the adhesive is easily affected by the external environment (temperature, humidity), thus forming hollows. If the adhesive height is at the upper limit of the control accuracy, although the full slurry effect is achieved, it is easy for a large amount of adhesive to overflow from the tile joints, affecting the automated paving process, and even failing to press down to the predetermined height.

As shown in Figures 1 to 5, the present invention discloses a ceramic tile and stone paving device, including a mobile chassis 1, on which a pumping machine 2 for supplying adhesive, a first scraping mechanism 4 for brushing adhesive on the surface of a floor tile 3, a second scraping mechanism 5 for brushing adhesive on the ground, and a dividing mechanism 6 for dividing the material coming from the pumping machine 2 are arranged, and the dividing mechanism 6 delivers the adhesive to the first scraping mechanism 4 and the second scraping mechanism 5; a mobile mechanical arm 7 for clamping the floor tile 3 and moving relative to the first scraping mechanism 4 to assist in brushing the adhesive is also arranged on the mobile chassis 1, and the mobile end of the mobile mechanical arm 7 is connected and fixed to the ground surface by a suction cup and other structures, so as to drive the floor tile to move.

The material distribution mechanism 6 of the present invention includes a material distribution terminal and a material delivery pipe 8, a material distribution chamber 9 is arranged inside the material distribution terminal, the material distribution chamber 9 is connected with the pumping machine 2 through the material delivery pipe 8, an upper discharge port 10 matching the size of the floor tile is arranged on the material distribution terminal, and a front discharge port 11 located below the upper discharge port 10, a first scraping mechanism 4 is arranged at the front side of the upper discharge port 10, a mobile mechanical arm 7 drives the floor tile 3 to move horizontally from above the upper discharge port 10 to apply adhesive to the lower surface of the floor tile 3; a second scraping mechanism 5 is arranged below the front discharge port 11, and the material distribution terminal distributes the adhesive through the upper discharge port and the front discharge port and controls the amount of adhesive applied through the first scraping mechanism 4 and the second scraping mechanism 5.

Since the adhesive itself is a viscous material, the uniformity of its distribution cannot be guaranteed during the flow process, which can easily lead to uneven distribution of the adhesive on the brushed surface, affecting the final laying effect of the floor tiles. In order to ensure the uniformity of the adhesive brushing distribution, as shown in Figures 4 and 5, the material distribution terminal of the present invention includes a material distribution portion 12 for forming a material distribution cavity 9 and connected to the feed pipe 8, and a material distribution portion 13 connected to the material distribution portion 12. The material distribution portion 13 adopts a cylindrical structure, and both ends are sealed by side covers 14. The material distribution portion 13 is vertically arranged above the material distribution portion 12, and the upper opening forms an upper discharge port 10, so that the upper discharge port is directly opposite to the glue-coated surface of the floor tiles.

A material distributing partition 15 with openings on the surface is arranged in the material distributing portion 12 of the present invention. The material distributing partition 15 is arranged along the length direction of the material distributing portion, and the plate surface covers all flow areas of the material distribution cavity in the material distributing portion 12 at the installation position, and diversion holes 16 are opened on the plate surface; the material distributing partition 15 includes a first material distributing partition close to the side where the material conveying pipe 8 is located and a second material distributing partition close to the side where the material distribution portion 13 is located; by setting the material distributing partition, the adhesive is evenly distributed in the material distribution cavity 9, and for the adhesive in the width direction area of the floor tiles, when the floor tiles are driven by the mobile robot 7 to translate, the adhesive can be evenly adhered to the surface of the ground.

The first scraping mechanism 4 of the present invention includes a first scraping tooth 17 and a baffle 18. The lower end of the first scraping tooth 17 is connected to the edge of the upper discharge port 10 through the baffle 18, and the upper end of the first scraping tooth 17 faces the side where the floor tile 2 is located. The thickness of the adhesive applied on the surface of the floor tile 3 is controlled by the first scraping tooth 17; the second scraping mechanism 5 includes a trough 19 for receiving the adhesive material flowing out of the front discharge port 11 and a second scraping tooth 20 arranged at the outlet end of the trough 19. The trough 19 is fixed on the mobile chassis 1 and moves with the mobile chassis 1 to brush the adhesive on the ground; during the floor tile paving process, during continuous operation, the pumping machine 2 keeps pumping material continuously to ensure that the adhesive on the floor tile Due to the adhesion effect of the agent, the actual amount of pumped material will be greater than the amount of material required for the floor tiles and the ground, and part of the material will fall from the upper discharge port 10. For this reason, the mobile chassis 1 of the present invention is fixedly provided with a connecting baffle 21 perpendicular to the moving direction, and the material trough 19 is fixed to the connecting baffle 21. The material distribution terminal and the material trough 19 are both on the board surface on the same side of the connecting baffle 12. The feed pipe 8 passes through the connecting baffle 21 and is connected to the pump 2 on the mobile chassis 1, so that the fallen material can enter the material trough 19 to be collected and used, reducing material loss. At the same time, it will not affect the rest of the area outside the paving, thereby ensuring that the paving operation can be carried out continuously and improving the efficiency of floor tile paving.

The present invention also discloses a method for laying ceramic tiles and stones, using the ceramic tiles and stones laying device, comprising the steps of:

S01, the pump conveys the adhesive, and after the adhesive is conveyed into the material dividing mechanism, it is divided by the material dividing mechanism to the first scraping mechanism and the second scraping mechanism;

The adhesive is transported by a pumping machine, first entering the material distribution chamber 9 from the material delivery pipe 8, first passing through the first material distribution partition in the material distribution chamber 9, and evenly distributing the adhesive into the material distribution chamber 9, and then evenly distributing the adhesive into the material distribution section 13 through the second material distribution partition, and moving toward the two discharge ports of the material distribution section 13. Part of the adhesive falls from the front discharge port 11 into the material trough 19 of the second material distribution mechanism. Since the adhesive is a viscous material, even if the height of the front discharge port 11 is lower than the upper discharge port 10, the adhesive will continue to flow upward to the upper discharge port 10 under the conveying power of the pumping machine. When the floor tile moves horizontally from the upper discharge port, the adhesive adheres to the lower surface of the floor tile, completing the back-wiping process of the floor tile;

S02, the mobile robot arm clamps the floor tile and moves above the first scraping mechanism, the adhesive is attached to the bottom of the floor tile, and a scraping-shaped adhesive coating is formed on the surface of the floor tile through the first scraping mechanism. The mobile chassis drives the second scraping mechanism to move along the ground, and a scraping-shaped adhesive coating is also formed on the ground surface. Then the mobile robot arm drives the floor tile to the floor tile laying area to lay ceramic tiles and stones. As for the thickness deviation of floor tiles from different manufacturers, the general deviation is about 1 to 2 mm. The mobile robot arm 7 can be used to adjust the appropriate height to meet the laying needs of ceramic tiles and stones of different thicknesses.
