[0035] In addition, the technical features involved in different embodiments of the present utility model described above can be combined with each other as long as they do not conflict with each other.

[0036] The present utility model provides a finished product kiln tail cracked brick detection device as shown in Figures 1 to 3 which aims to solve the drawback that the existing method for identifying cracked bricks in the kiln tail stage is very labor-consuming.

[0037] The finished product kiln tail cracked brick detection device mainly includes: a positioning baffle 200, a photoelectric inductor 310, and a plurality of feeding roller tables 100, all of which are arranged on a frame 900.

[0038] The plurality of feeding roller tables 100 are arranged at intervals along the moving direction. There is a detection area on the feeding roller table 100 at the end of the moving direction. The plurality of feeding roller tables 100 are used to drive the ceramic tile 800 to move towards the detection area at different driving speeds. The driving speeds of the plurality of feeding roller tables 100 increase sequentially along the moving direction. Specifically, the feeding roller table 100 drives the ceramic tile 800 to move by applying frictional force to the bottom surface and / or top surface of the ceramic tile 800, or by applying a force in the moving direction after adsorbing the ceramic tile 800 with a suction cup to drive the ceramic tile 800 to move. The driving speed can be set manually, such as 0.01 m / s - 1 m / s, and is not limited herein. For the convenience of description, the moving direction is called the front, and the direction opposite to the moving direction is called the rear. The number of the feeding roller tables 100 is set to two (the front feeding roller table 100 and the rear feeding roller table 100). The driving speed of the front feeding roller table 100 is greater than that of the rear feeding roller table 100. During actual use, after the ceramic tile 800 comes out of the kiln, it first moves onto the rear feeding roller table 100. At this time, the ceramic tile 800 moves according to the driving speed of the rear feeding roller table 100. When the ceramic tile 800 comes into contact with the front feeding roller table 100, the front end of the ceramic tile 800 is in contact with the front feeding roller table 100 and the rear end is in contact with the rear feeding roller table 100. Since the driving speed of the front feeding roller table 100 is greater than that of the rear feeding roller table 100, the moving speed of the front end of the ceramic tile 800 is greater than that of the rear end of the ceramic tile 800. At this time, a forward force will be generated at the front end of the ceramic tile 800, and the rear end of the ceramic tile 800 will be subjected to a backward force under the action of the rear feeding roller table 100. When the ceramic tile 800 is broken (there is a crack between the front end and the rear end), the front end and the rear end of it will be separated due to the forces in opposite directions, and the length of the ceramic tile 800 in the moving direction will become larger; on the contrary, when the ceramic tile 800 is intact, the forces in opposite directions on its front end and rear end will not have too much impact on its body.

[0039] Preferably, in order to better handle the cracks of the tile 800 in different directions, the number of the feeding roller tables 100 within the unit length in the moving direction can be increased to better separate each part (including but not limited to the front end and the rear end) of the tile 800 in the moving direction.

[0040] The positioning baffle 200 is used to position the tile 800 that moves into the detection area, and the photoelectric sensor 310 is used to detect whether the tile 800 located in the detection area is broken. Specifically, when the tile 800 is broken (there is a crack between the front end and the rear end), the front end and the rear end of it are subjected to forces in opposite directions, which will cause the front end and the rear end to separate, and the length of the tile 800 in the moving direction becomes larger. The photoelectric sensor 310 can detect the length of the tile 800 in the moving direction and compare it with the length of the intact tile 800 in the moving direction to determine whether the tile 800 is intact.

[0041] Since the tile 800 is relatively fragile, cracked tiles are likely to occur at the tail end of the kiln. If the cracked tiles are not removed in time when they occur at the tail end of the kiln, the cracked tiles are likely to get stuck when entering the subsequent glaze line, resulting in blockage of the glaze line and affecting production efficiency. And currently, the common solution to judge whether a tile is broken is usually to arrange manual monitoring, which is very time-consuming and laborious.

[0042] The utility model drives the tile 800 to move towards the detection area by setting a plurality of feeding roller tables 100, and the plurality of feeding roller tables 100 apply different driving speeds to several parts of the tile 800 in the moving direction, so that the adjacent two parts are subjected to opposite frictional forces to separate the cracked tile. Finally, it indirectly judges whether the tile 800 located in the detection area is broken through the signal of the photoelectric sensor, saving labor.

[0043] In one embodiment, as Figure 1 , Figure 2 , Figure 3 shown, the feeding roller table 100 includes: a plurality of feeding rollers 110 and a feeding motor.

[0044] The plurality of feeding rollers 110 are arranged at intervals along the moving direction, the plurality of feeding rollers 110 are rotatably arranged on the frame 900, the plurality of feeding rollers 110 rotate synchronously, and the tile 800 is located on the plurality of feeding rollers 110 and is driven by the frictional force of the plurality of feeding rollers 110 to move towards the detection area. The feeding motor is arranged on the frame 900, and the plurality of feeding rollers 110 are driven by the feeding motor to rotate to drive the tile 800 towards the detection area.

[0045] In one embodiment, as Figure 1 , Figure 2 , Figure 3 shown, the positioning baffle 200 includes: a baffle body 210 and a baffle driving assembly.

[0046] The baffle body 210 and the baffle driving assembly are both arranged on the frame 900. The tile 800 moved to the detection area is blocked by the baffle body 210 and stays on the detection area. The surface of the baffle body 210 facing away from the moving direction contacts the tile 800, and the baffle body 210 is driven by the baffle driving assembly to separate from the tile 800. Specifically, after being driven by the driving assembly, the baffle body 210 can separate from the tile 800 by means of rotation, translation, telescoping, etc.

[0047] In one embodiment, as Figure 1 , Figure 2 , Figure 3 shown, the baffle driving assembly includes: a rotating shaft 220 and a baffle motor.

[0048] The rotating shaft 220 is rotatably arranged on the frame 900. The baffle body 210 is arranged on the rotating shaft 220. The rotating shaft 220 is arranged on the frame 900. The rotating shaft 220 is driven by the baffle motor to drive the baffle body 210 to move towards the moving direction so that the baffle body 210 separates from the tile 800.

[0049] In one embodiment, as Figure 1 , Figure 2 , Figure 3 shown, the photoelectric inductor 310 includes: a front photoelectric inductor 311 and a rear photoelectric inductor 312.

[0050] Both the front photoelectric inductor 311 and the rear photoelectric inductor 312 are arranged on the frame 900. The detection position of the front photoelectric inductor 311 is adjacent to one end of the positioning baffle 200 facing away from the moving direction. The distance between the detection position of the front photoelectric inductor 311 and one end of the positioning baffle 200 facing away from the moving direction is preferably between 0.1 mm and 1 mm. The detection position of the rear photoelectric inductor 312 and the detection position of the front photoelectric inductor 311 are arranged at intervals along the moving direction in the detection area, and the distance between the detection position of the rear photoelectric inductor 312 and the detection position of the front photoelectric inductor 311 (as Figure 2 shown as b) is greater than the length of the intact tile 800 in the moving direction (as Figure 2 shown as a).

[0051] Specifically, when the tile 800 is blocked by the positioning baffle 200 and stays in the detection area, the distance between the front photoelectric inductor 311 and the rear photoelectric inductor 312 can be considered the same as the distance between the detection position of the rear photoelectric inductor 312 and the positioning baffle 200.

[0052] Specifically, the detection positions of the front photoelectric sensor 311 and the rear photoelectric sensor 312 are the positions irradiated by the laser. The front photoelectric sensor 311 and the rear photoelectric sensor 312 can obtain the distance between them and their detection positions (e.g., 10 cm). The ceramic tile 800 is arranged between the photoelectric sensor 310 and several feeding rollers 110. When the photoelectric sensor 310 detects the detection area, when the ceramic tile 800 or a part of the ceramic tile 800 is located between the photoelectric sensor 310 and several feeding rollers 110, and at this time the detection position of the corresponding photoelectric sensor 310 is located on the ceramic tile 800 or a part of the ceramic tile 800, the corresponding photoelectric sensor 310 can recognize that the distance between it and its detection position is reduced (e.g., 10 cm minus the thickness of the ceramic tile) to determine whether there is a ceramic tile 800 at its detection position. The distance between the detection position of the rear photoelectric sensor 312 and the detection position of the front photoelectric sensor 311 is greater than the length of a complete ceramic tile 800 in the moving direction. During actual use, when the front photoelectric sensor 311 detects that there is a ceramic tile 800 at its detection position, the finished product kiln tail cracked brick detection device can judge whether the ceramic tile 800 is intact through the rear photoelectric sensor 312 (when the rear photoelectric sensor 312 detects that there is a ceramic tile 800 at its detection position, it means that the length of the ceramic tile 800 in the moving direction is greater than the length of a complete ceramic tile 800 in the moving direction, then it can be judged that the ceramic tile 800 is a cracked brick; on the contrary, when the rear photoelectric sensor 312 detects that there is no ceramic tile 800 at its detection position, it means that the length of the ceramic tile 800 in the moving direction is not greater than the length of a complete ceramic tile 800 in the moving direction, then it can be judged that the ceramic tile 800 is a complete ceramic tile 800).

[0053] In one embodiment, as Figure 1 and Figure 2 shown in, the finished product kiln tail cracked brick detection device further includes: several telescopic rods 910. One ends of the several telescopic rods 910 are arranged on the frame 900, and the other ends are respectively arranged on the front photoelectric sensor and the rear photoelectric sensor. Among them, the several telescopic rods 910 are respectively slidably arranged on the frame 900 along the direction perpendicular to the moving direction, and the several telescopic rods 910 are used for telescoping along the moving direction.

[0054] During actual use, the ceramic tile is horizontally arranged, the telescopic rods 910 are horizontally arranged. Through the telescoping of the several telescopic rods 910, the front photoelectric sensor 311 and the rear photoelectric sensor 312 can move along the moving direction, so as to increase or decrease the distance between the front photoelectric sensor 311 and the rear photoelectric sensor 312 to cope with ceramic tiles of different specifications; similarly, by sliding the several telescopic rods 910 along the direction perpendicular to the moving direction, the positions of the front photoelectric sensor 311 and the rear photoelectric sensor 312 can be changed to cope with ceramic tiles of different specifications.

[0055] In one embodiment, asFigure 1 , Figure 2 , Figure 3 As shown in Figure 3 , both the front photoelectric sensor 311 and the rear photoelectric sensor 312 are perpendicular to the ceramic tile 800 located in the detection area, which can increase the accuracy.

[0056] In one embodiment, the surface roughness of several of the feeding roller tables 100 is the same. Preferably, in order to prevent excessive external force on the ceramic tile 800, several feeding roller tables 100 can drive the ceramic tile 800 to move through friction. By changing the friction between the feeding roller table 100 and the ceramic tile 800, the maximum external force applied between the front end and the rear end of the ceramic tile 800 by the feeding roller table 100 can be changed to prevent the intact ceramic tile 800 from being damaged by excessive external force.

[0057] In one embodiment, as Figure 1 , Figure 2 , Figure 3 As shown in Figure 3 , the finished product kiln tail cracked brick detection device further includes: a positioning roller table, which is arranged between the feeding roller table 100 and the positioning baffle 200, and the detection area is located on the positioning roller table;

[0058] A discharging roller table 500, the positioning baffle 200 is arranged between the feeding roller table 100 and the discharging roller table 500, and the discharging roller table 500 is used to drive the ceramic tile 800 located in the detection area to move in the moving direction;

[0059] A brick receiving platform 600, which is arranged at one end of the discharging roller table 500 in the moving direction, and the brick receiving platform 600 is used to receive the ceramic tile 800 driven by the discharging roller table 500.

[0060] In one embodiment, as Figure 1 , Figure 3 As shown in Figure 3 , the finished product kiln tail cracked brick detection device further includes: a lifting belt 700, which is arranged on the discharging roller table 500, and the ceramic tile 800 located on the discharging roller table 500 is driven by the lifting belt 700 to leave the discharging roller table 500.

[0061] Specifically, the intact ceramic tiles 800 and the cracked bricks can be classified by the discharging roller table 500 and the lifting belt 700. For example, when the photoelectric sensor 310 determines that the ceramic tile 800 on the positioning roller table is a cracked brick, the lifting belt 700 does not act, and the cracked brick is conveyed by the discharging roller table 500 to the brick receiving platform 600; when the photoelectric sensor 310 determines that the ceramic tile 800 on the positioning roller table is an intact ceramic tile 800, the lifting belt 700 acts, and the intact ceramic tile 800 is conveyed by the lifting belt 700 to other positions / lines for discharging.

[0062] Preferably, a plurality of baffle driving components are provided. A plurality of tiles 800 are arranged at intervals on the feeding roller table 100 in a direction perpendicular to the moving direction. The plurality of baffle driving components correspond to the plurality of tiles 800 one by one. After the lifting belt rises, it can contact any tile 800 located on the discharging roller table 500 and convey it to other positions / lines for discharging.

[0063] Among them, when all the tiles 800 on the feeding roller table 100 are cracked tiles, the baffle bodies 210 of the plurality of baffle driving components are separated from the corresponding tiles 800, and the lifting belt 700 does not act. At this time, all the cracked tiles move to the brick receiving platform 600 through the discharging roller table 500.

[0064] When all the tiles 800 on the feeding roller table 100 are intact tiles 800, the baffle bodies 210 of the plurality of baffle driving components are separated from the corresponding tiles 800. During this period, the lifting belt 700 acts. At this time, all the intact tiles 800 come into contact with the lifting belt 700 and are conveyed to other positions / lines for discharging.

[0065] When the tiles 800 on the feeding roller table 100 include intact tiles 800 and cracked tiles, the intact tiles 800 are blocked by the baffle bodies 210 and stay in the detection area. During this period, the lifting belt 700 does not act. At this time, all the cracked tiles move to the brick receiving platform 600 through the discharging roller table 500; then / before that, the baffle bodies 210 corresponding to the intact tiles 800 are separated from them. The intact tiles 800 reach above the lifting belt 700 through the discharging roller table 500, and the lifting belt 700 acts. At this time, all the intact tiles 800 come into contact with the lifting belt 700 and are conveyed to other positions / lines for discharging.

[0066] In summary, a cracked tile detection device for the tail of a finished product kiln is provided, including a positioning baffle, a photoelectric sensor, and a plurality of feeding roller tables all arranged on a frame. The plurality of feeding roller tables are arranged at intervals along the moving direction. There is a detection area on the feeding roller table at the end of the moving direction. The plurality of feeding roller tables respectively drive the tiles to move towards the detection area at driving speeds that increase sequentially along the moving direction. The distance between the photoelectric sensor and the positioning baffle is greater than the length of an intact tile in the moving direction. The utility model drives the tiles to move towards the detection area by setting a plurality of feeding roller tables, and the plurality of feeding roller tables apply different driving speeds to several parts of the tiles in the moving direction so that opposite frictional forces are applied between every two adjacent parts to separate the cracked tiles. Finally, it is indirectly judged whether the tiles located in the detection area are cracked through the signal of the photoelectric sensor, saving labor.

[0067] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the creation of the present utility model.
