Description

Technical Field

[0001] This utility model relates to the field of ceramic machinery and equipment technology, and in particular to a device for centering ceramic brick blanks on a conveyor line. Background Technology

[0002] At the end of the ceramic production line, before the packaging process, the ceramics produced by the firing and air-cooling lines need to be positioned correctly to assist the subsequent packaging robots in accurately placing the finished tiles onto the packaging boxes. The deviation angle on the line cannot exceed 1 degree; otherwise, the edges of the tiles may easily scratch the packaging boxes during subsequent packing. Currently, existing ceramic production lines use a screw-type centering machine to perform the final centering of the tiles. This screw-type centering machine uses a bottom synchronous screw to push the push plates on both sides towards the center at the same speed and with the same stroke. In this way, the tiles transported from the conveyor belt mechanism will be centered under the simultaneous push of the push plates on both sides. It has the characteristic of small centering error. However, this type of equipment also has problems such as slow centering speed, greater damage to the tile blanks, easy wear and tear and lack of durability, and troublesome subsequent maintenance and after-sales service.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] refer to Figures 1 to 8 :

[0027] This embodiment provides a device for centering ceramic tile 101 blanks on a conveyor line, including a frame 10A and a conveyor belt mechanism 20A mounted on the frame 10A. The front and rear ends of the conveyor belt of this device are connected to the air-cooling line and the packaging line in the ceramic tile 101 kiln production line, respectively. The air-cooling line conveys the cooled ceramic tile 101 to the conveyor belt mechanism 20A of this device. After centering, it enters the packaging line, where it is picked up by a robot and boxed. Due to the various axis differences of the conveyor belts and rollers of the firing line and air-cooling line at the front end, the delivered ceramic tile 101 may deviate in various ways, which is not conducive to subsequent packaging. Therefore, this device aims to center the ceramic tile 101 and... To straighten the angle of the tile 101 and prevent it from scratching the packaging box when it is placed flat in the packaging box, a centering mechanism 30A is installed on both sides of the conveyor belt mechanism 20A. The centering mechanism 30A includes a first centering component 100 and a second centering component 200. Both the first centering component 100 and the second centering component 200 include a mounting frame 300, a three-axis cylinder 1 and a brick-pushing wheel assembly 2. The mounting frame 300 is installed on the frame 10A. The three-axis cylinder 1 is installed on the mounting frame 300 and its output end is connected to the brick-pushing wheel assembly 2. The brick-pushing wheel assemblies 2 installed on both sides are pushed towards the center of the frame 10A under the action of the three-axis cylinder 1 to center and straighten the tile 101.

[0028] Specifically, the triaxial cylinder 1 includes a main cylinder body 11, a main push rod 12, and a guide rod 13. The main cylinder body 11 is mounted on a mounting bracket 300. Guide holes 14 are provided on both sides of the main cylinder body 11. The main push rod 12 is connected to the output end of the main cylinder body 11. The brick-pushing wheel assembly 2 includes a channel steel component 21 and a guide wheel 22. The guide wheels 22 are longitudinally rotatably mounted on the inner side of the channel steel component 21 in a plurality of configurations. The back side of the channel steel component 21 is connected to the main push rod 12 and the guide rod 13, respectively. The main push rod 12 is located in the middle position, and the guide rod 13 is located on both sides, with the guide rod 13 positioned exactly within the guide hole 14. With the internal guide sliding, when the main push rod 12 pushes forward or pulls the channel steel part 21 backward, the guide rods 13 on both sides act as guides and limits, forming a three-axis linkage. Its telescopic structure is more stable, less prone to slippage, and has smaller errors. Specifically, the stop wheel 22 is a rubber wheel with cushioning properties. Combined with its longitudinal rotation characteristics, when the tile 101 is brought over by the conveyor belt, it can be pushed and straightened directly without deliberately slowing down, and there will be no hard collision with the tile 101. The tile 101 can continue to move during the pushing and straightening process, and its movement is accompanied by the rotation of the stop wheel 22.

[0029] Specifically, for faster maintenance, normal production lines generally cannot be shut down, as a shutdown would mean stopping the entire production line, resulting in significant losses and delays. Restarting would require lengthy preheating and debugging processes. Therefore, the maintenance and installation of such production line equipment generally needs to be done as quickly as possible. Here, the centering mechanism 30A also includes a centering crossbeam 400, which is positioned above the frame 10A and passes through the conveyor belt mechanism 20A in its middle. The mounting brackets 300 are positioned on both sides of the centering crossbeam 400. With this configuration, the lower end of the centering crossbeam 400 passes through the conveyor belt, and its two sides are respectively connected to... Mounting bracket 300 adopts a modular integrated design, which integrates a three-axis cylinder 1 and a brick-pushing wheel assembly 2. If a component on one side fails, only that side's mechanism can be stopped for quick replacement. If both sides fail, a better approach is to first install the first centering assembly 100 and the second centering assembly 200 on the spare centering crossbeam 400, and then directly install the assembled unit onto the frame 10A. This setup allows for quick replacement without stopping the machine. The tiles 101 that are passed through during the replacement process can be marked, and then manually removed or packed. Normal replacement and installation can be completed in just one or two minutes.

[0030] Specifically, the channel steel component 21 is horizontally distributed, the guide wheel 22 is longitudinally distributed, and the inner side of the channel steel component 21 is provided with a first rotating shaft 211, through which the guide wheel 22 rotates.

[0031] Specifically, the conveyor belt mechanism 20A includes a main shaft 31, a driven shaft 32, a drive wheel 33, a driven wheel 34, a belt 35, and a motor 36. The main shaft 31 and the driven shaft 32 are both mounted on the frame 10A via bearings. The drive wheel 33 is mounted on the main shaft 31, and the driven wheel 34 is mounted on the driven shaft 32. The motor 36 is located on one side of the frame 10A, and its output end is connected to the main shaft 31 for driving. The belt 35 is sleeved between the drive wheel 33 and the driven wheel 34, thus achieving synchronization of the conveyor belt.

[0032] Specifically, during the transmission process, the upper end of the conveyor belt also needs to bear the weight of the tile 101 passing by. Therefore, in order to prevent the conveyor belt from collapsing and affecting its transmission efficiency, and to avoid deviation later, the conveyor belt mechanism 20A also includes a bracket mechanism. The bracket mechanism includes a lifting horizontal frame 41 and a lifting vertical frame 42. The lifting horizontal frame 41 is set on the frame 10A through the first height adjustment components 410 on both sides. The lifting vertical frame 42 is set on the lifting horizontal frame 41 through the second height adjustment component 420. The lifting vertical frame 42 extends parallel to the lower end of the belt 35. With this arrangement, the lower end of the conveyor belt is supported by the lifting vertical frame 42, so it will not collapse due to the upper end being pressed by the tile 101. As a subsequent improvement embodiment, the lifting vertical frame 42 is also provided with a wheel to help reduce friction when the conveyor belt moves.

[0033] Specifically, the first height adjustment component 410 includes a first clamp 411 and a first bolt 412. The first clamp 411 is clamped on the frame 10A. One end of the first bolt 412 is fixedly connected to the first clamp 411, and the other end passes through the lifting crossbeam 41 and is fixed thereto. The second height adjustment component 420 includes a second clamp 421 and a second bolt 422. The second clamp 421 is clamped on the lifting vertical frame 42. The lifting crossbeam 41 is provided with a long groove 41a in a parallel direction. One end of the second bolt 422 is fixedly connected to the second clamp 421, and the other end passes through the long groove 41a and is movably installed and fixed to the long groove 41a. Here, the bolt refers to a combination of a screw and a nut, which is clamped with the screw by two nuts.

[0034] Specifically, the centering mechanism 30A relies on the rapid extension of the main cylinders 11 on both sides during operation. Its stroke is preset according to the different sizes of the tiles 101. However, in some cases, such as damage to one side of the centering mechanism 30A or loose screws causing a deviation in its extension stroke, the tile 101 may not be aligned or centered when passing through the centering mechanism 30A. This also includes a verification mechanism, which comprises a first photoelectric sensor 51, a second photoelectric sensor 52, and a first laser rangefinder 5. 3. The first photoelectric sensor 51 and the second photoelectric sensor 52 are installed on both sides of the frame 10A and at the rear end of the centering mechanism 30A. The first optical rangefinder and the second laser rangefinder 54 are installed on both sides of the frame 10A and at the rear end of the first photoelectric sensor 51 and the second photoelectric sensor 52. The verification principle of this patent is that after the tile 101 is centered and aligned by the centering mechanism 30A, it passes through the area of ​​the first photoelectric sensor 51 and the second photoelectric sensor 52. The system senses that a tile 101 has passed by and that it is the same tile 101, so the conveyor belt continues to move forward. The tile 101 is brought to the area of ​​the first laser rangefinder 53 and the second laser rangefinder 54. The first laser rangefinder 53 and the second laser rangefinder 54 each take three points on the moving tile 101, and calculate the distances of six points in total (the distances between the two side lines of the tile 101 and the first laser rangefinder 53 or the second laser rangefinder 54). When the deviation of the six points is less than 0.1cm, it is determined that the tile 101 is centered and straightened. Here, taking an 80cm by 80cm tile 101 as an example, it passes through the centering mechanism 30A. If the tile is off-center and at an incorrect angle, the distances of the three points taken on the left side of the centering mechanism 30A are 11.5, 11.2, and 10.9, and the distances of the three points taken on the right side are 10.9, 11.2, and 11.5. At this time, the distance deviation of the six points is greater than 0.1cm, so the system will determine that the centering mechanism 30A has not completed the centering and straightening, and it needs to be inspected or replaced. When the distance difference of the six points is less than 0.1cm, it is determined that the tile 101 has been centered and straightened, and other cases are deduced in the same way.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
