Description

Technical Field

[0001] The present invention relates to the technical field of ceramic tile production auxiliary equipment, and in particular to a distributed coloring and marking device dedicated to ceramic tiles and a control method thereof. Background Art

[0002] To improve production efficiency, existing tile factories generally adopt a parallel operation model: multiple production lines may operate simultaneously, or each processing stage of a production line may have multiple locations with the same function for processing different products simultaneously. Different products will pass through each process along a set path according to production needs. These production lines include a complete process of raw material processing, molding, high-temperature firing, drying and trimming, and decorative glazing, and are ultimately combined into a single packaging production line through a transfer system. During the quality inspection stage before packaging, the qualification of the tile products must be strictly screened. For example, if uneven pigment distribution is found, it can be directly determined that there is a problem with the decorative glazing process.

[0003] However, because products produced on various production lines or at different process locations are difficult to distinguish from their source after being combined, once a quality issue is detected, it is often impossible to quickly pinpoint the specific production line, equipment, or process location where the anomaly occurred. This tracing dilemma not only results in lengthy troubleshooting and disrupts production, but can also lead to widespread quality problems due to the inability to promptly mitigate losses. Summary of the Invention

In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0049] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0050] A distributed coloring and marking device for tiles, comprising a transfer device 1, a first conveying device 2, a second conveying device 3, a sorting device 4 and a coloring and marking device 5;

[0051] The transfer device 1 includes a first transfer component 11 and a second transfer component 12. The conveying direction of the first transfer component 11 is defined as a first conveying direction, and the conveying direction of the second transfer component 12 is defined as a second conveying direction. The first conveying direction and the second conveying direction are perpendicular to each other, and the first transfer component 11 and the second transfer component 12 operate alternately.

[0052] The conveying direction of the first conveying device 2 is the first conveying direction. The output end of the first conveying device 2 is docked with the input end of the first transfer component 11. The sorting device 4 is arranged between the output end of the first conveying device 2 and the input end of the first transfer component 11. The first conveying device 2 is used to receive the tiles 6 produced in the parallel operation mode and transport them to the first transfer component 11 according to the first conveying direction. The sorting device 4 is used to perform position correction and arrangement adjustment on the multiple tiles 6, so that the multiple tiles 6 form a single side-aligned parallel queue and enter the first transfer component 11;

[0053] The coloring and marking device 5 is provided at the output end of the first transfer component 11. The coloring and marking device 5 includes a plurality of coloring markers 51 arranged at intervals. The plurality of coloring markers 51 are used to color the single side edges of the parallel tiles 6 transferred by the first transfer component 11 one by one, so as to mark products of different production lines.

[0054] The second transfer component 12 is used to lift the marked parallel tiles 6 steadily and separate them from the first transfer component 11 and the coloring marking device 5, and transport them to the second conveying device 3 in the second conveying direction. The conveying direction of the second conveying device 3 is the second conveying direction. The input end of the second conveying device 3 is docked with the output end of the second transfer component 12. The second conveying device 3 is used to transport the marked parallel tiles 6 to the rear-end detection and packaging link in the second conveying direction.

[0055] like Figure 1-5 As shown in the figure, in the context of the existing tile factory 6 adopting a parallel operation mode and the difficulty in tracing the source of products after merging, the distributed coloring and marking equipment dedicated to tile 6 is installed before the products are fired and enter the transportation and merging link, and is used to uniquely mark the tiles 6. The specific working principle is as follows:

[0056] This equipment coordinates the coordinated operation of various devices through the PLC controller to achieve automated marking and transportation. After receiving the linkage signal, the PLC controller starts the first conveying device 2 to run along the first conveying direction, receives the tiles 6 produced in the parallel operation mode and conveys them forward. Since the tiles 6 produced in the parallel operation mode may have position offsets, irregular arrangements, etc., the sorting device 4 between the output end of the first conveying device 2 and the input end of the first transfer component 11 will perform position correction and arrangement adjustments on the tiles 6, so that the multiple tiles 6 that may have been randomly distributed form a single side-aligned parallel queue, and then through the precise docking of the first conveying device 2 and the first transfer component 11, the sorted parallel tiles 6 are smoothly delivered to the first transfer component 11, laying the foundation for the accuracy of subsequent coloring and marking.

[0057] The PLC controller synchronously controls the first transfer assembly 11 to operate in a first conveying direction, smoothly transporting the parallel tiles 6 to the location of the coloring and marking device 5 before stopping. At this point, the coloring and marking device 5 has multiple, spaced-apart coloring markers 51 aligned with individual sides of the parallel tiles 6, applying a unique coloring process using specialized inks such as invisible ink or low-impact colorants. Tiles 6 from different production lines are marked with different colors or patterns, and the markings are confined to a single side, ensuring no impact on the product's appearance or performance.

[0058] After marking is complete, the PLC controller instructs the coloring and marking device 5 to reset and simultaneously controls the transfer device 1 to switch to the second transfer component 12. The second transfer component 12 steadily lifts the marked parallel tiles 6, separating them from the first transfer component 11 and the coloring and marking device 5. This allows the originally marked sides to hang in the air to dry, preventing the newly completed markings from being damaged by friction or contaminated by stains. Subsequently, the second transfer component 12 transfers the tiles 6 to the second conveying device 3 along the second conveying direction. The second conveying device 3 receives and transports these marked tiles 6 along the second conveying direction, ultimately delivering them to the back-end inspection and packaging process.

[0059] Through this process, tiles 6 from different production lines are assigned unique "identities" before being combined. When manual or machine quality inspection identifies substandard products, the side markings can be used to pinpoint the source production line. Combined with tile 6 defect information corresponding to different processes, as shown in the table below, the problematic process can be quickly identified and traced back to the corresponding equipment for targeted repairs, effectively improving problem-solving efficiency and minimizing production losses.

[0060]

[0061]

[0062] It should be noted that the parallel operation mode may involve multiple production lines, each of which sequentially includes processes such as raw material processing, molding, high-temperature firing, drying and trimming, and decorative glazing. Products with the same process are products produced in the parallel operation mode. Alternatively, a production line may have multiple processing paths, each of which sequentially includes processes such as raw material processing, molding, high-temperature firing, drying and trimming, and decorative glazing. Multiple process positions with the same function are set up at each process stage along the width. For example, four paths are arranged side by side in a firing kiln, and each path corresponds to a firing process position. Each firing process position corresponds to a product. The four products are moved side by side along the width of the kiln to complete the firing, which is the product produced in the parallel operation mode. The four tiles removed from the four firing processes are color-coded according to the product information. If the four tiles are the same product, they are all marked with the same color. If there are several product types, different color coding is used to distinguish them.

[0063] To further illustrate, the arranging device 4 includes an arranging cylinder 41, an arranging baffle 42, an arranging base 43 and an arranging guide 44;

[0064] The arranging cylinder 41 is fixedly mounted on the arranging base 43, and the telescopic end of the arranging cylinder 41 is fixedly mounted on the lower side of the arranging baffle 42. The arranging cylinder 41 is used to drive the arranging baffle 42 to rise or fall so as to be higher or lower than the conveying surface of the first conveying device 2;

[0065] The arranging guide plates 44 are vertically mounted on both ends of the arranging base 43 , and the facing surfaces of the two arranging guide plates 44 are provided with guide grooves 45 . The two side edges of the arranging baffle 42 are slidably mounted in the two guide grooves 45 .

[0066] like Figure 3-5 As shown, when the first conveyor 2 is transporting multiple tiles 6, the sorting device 4 is activated according to a preset program in the PLC controller. The sorting cylinder 41 drives the sorting baffle 42, guided by two guide grooves 45, to an appropriate height, high enough above the conveying surface of the first conveyor 2 so that the tile-blocking surface of the sorting baffle 42 contacts the side edges of the multiple tiles 6. During contact with the tiles 6, the sorting baffle 42 corrects the position of the tiles 6 by blocking them, allowing the individual side edges of the multiple tiles 6 to gradually contact the sorting baffle 42, thereby achieving neat and parallel arrangement. When the multiple tiles 6 are sorted, the sorting cylinder 41 drives the sorting baffle 42 to descend rapidly, allowing the sorted parallel tiles 6 to smoothly enter the first transfer assembly 11, ensuring a stable and reliable sorting effect.

[0067] Furthermore, the tile blocking surface of the finishing baffle 42 may be provided with a wear-resistant and damage-resistant layer to avoid scratching or damaging the tiles 6 .

[0068] To further illustrate, the color marking device 5 also includes a color marking workbench 52, a color marking support 53, a color marking rotating shaft 54, a color marking cylinder 55 and a color marking connecting rod 56;

[0069] The coloring marking workbench 52 is provided with the coloring marking supports 53 at both ends, and the coloring marking rotating shaft 54 ​​is rotatably mounted between the two coloring marking supports 53. A plurality of coloring markers 51 arranged at intervals are detachably mounted on the shaft of the coloring marking rotating shaft 54. Ink cartridges 57 are placed on the surface of the coloring marking workbench 52 corresponding to the plurality of coloring markers 51.

[0070] The coloring marking cylinder 55 is fixedly mounted on the lower end of the coloring marking workbench 52 , and the telescopic end of the coloring marking cylinder 55 is rotatably mounted with one end of the coloring marking connecting rod 56 , and the other end of the coloring marking connecting rod 56 is fixedly mounted on the coloring marking rotating shaft 54 ​​.

[0071] like Figure 3-5 As shown, the PLC controller triggers the coloring and marking device 5 to operate according to the preset production line and marker correspondence rules. First, the coloring and marking cylinder 55 is controlled to extend its telescopic end, driving the coloring and marking connecting rod 56 to move, thereby causing the coloring and marking rotating shaft 54 ​​to rotate on the coloring and marking support 53, allowing the multiple coloring and marking devices 51 mounted on the rotating shaft to rotate downward and dip into the pigment in the corresponding ink cartridges 57 on the surface of the coloring and marking workbench 52. Subsequently, the telescopic end of the coloring and marking cylinder 55 is retracted, driving the rotating shaft to rotate in the opposite direction through the connecting rod, causing the coloring and marking devices 51 to rotate upward and remain suspended and stationary on the side of the first transfer assembly 11. The resting position of the coloring and marking device 51 can be equal to or slightly higher than the conveying surface of the first transfer assembly 11, waiting to contact a single side of multiple parallel tiles 6 for one-to-one coloring.

[0072] It should be noted that the spacing between the multiple colored markers 51 mounted on the marking shaft 54 ​​can be adjusted based on the actual size of the tile 6. The static positions of the multiple colored markers 51 can also be adjusted based on the actual thickness of the tile 6. The colored markers 51 only need to leave a mark on the side of the tile 6 to distinguish the tiles 6, without requiring that the markings on each tile be uniform. The colored markers 51 can be configured as rollers, high-density sponges, or pattern stamps.

[0073] To further illustrate, the first transfer assembly 11 includes a first transfer bracket 111 , a first transfer support 112 , a first transfer rotating shaft 113 and a first transfer motor 114 ;

[0074] A plurality of first transfer supports 112 spaced apart are fixedly mounted on both ends of the first transfer bracket 111. A first transfer rotating shaft 113 is rotatably mounted between two first transfer supports 112 facing each other. A first driven transmission belt 115 is sleeved on the same end of adjacent first transfer rotating shafts 113.

[0075] The first transfer motor 114 is installed inside the first transfer bracket 111 , and a first active transmission belt 116 is sleeved between the output end of the first transfer motor 114 and one end of the first transfer rotating shaft 113 .

[0076] like Figure 3-4 As shown, when the first conveyor device 2 delivers the sorted parallel tiles 6 to the input end of the first transfer assembly 11, the PLC controller instructs the first transfer motor 114 to start. The output end of the first transfer motor 114 drives a first transfer rotating shaft 113 connected to it to rotate via a first driving transmission belt 116. Because adjacent first transfer rotating shafts 113 are connected to the same end via a first driven transmission belt 115, power is transmitted sequentially through the transmission belts, causing all first transfer rotating shafts 113 to rotate synchronously.

[0077] Because the first rotating shaft is mounted on the first transfer supports 112 at both ends of the first transfer bracket 111, the friction between the shaft and the bottom of the tiles 6 during rotation smoothly transports the parallel tiles 6 along the first conveying direction. By controlling the speed of the first transfer motor 114, the conveying speed of the rotating shaft can be adjusted, ensuring that the tiles 6 accurately reach the corresponding marking station of the coloring and marking device 5, providing stable material support for subsequent coloring and marking operations.

[0078] To further illustrate, the second transfer assembly 12 includes a lifting cylinder 121, a second transfer bracket 122 and a second transfer motor 123;

[0079] The plurality of lifting cylinders 121 are fixedly mounted on the first transfer bracket 111, and the telescopic ends of the plurality of lifting cylinders 121 are fixedly mounted on the bottom end of the second transfer bracket 122. The second transfer bracket 122 is arranged inside the first transfer bracket 111. The second two ends of the second transfer bracket 122 are rotatably mounted with a second active rotating shaft 124 and a second driven rotating shaft 125. The length direction of the second active rotating shaft 124 and the length direction of the second driven rotating shaft 125 are perpendicular to the length direction of the first transfer rotating shaft 113. The second active rotating shaft 124 is located below the second driven rotating shaft 125.

[0080] The second transport motor 123 is installed inside the second transport bracket 122. The output end of the second transport motor 123 and the center of the second active rotating shaft 124 are fixedly mounted with second driving wheels 126. A second active transmission belt 127 is sleeved between the two second driving wheels 126.

[0081] A second driven wheel 128 is fixedly mounted on the shaft body of the second driving rotating shaft 124 and the shaft body of the second driven rotating shaft 125 , and a second driven transmission belt 129 is sleeved between the two second driven wheels 128 ;

[0082] The shaft body of the second active rotating shaft 124 is also fixedly mounted with a plurality of pulleys 1210 , and the plurality of pulleys 1210 and the plurality of the first transfer rotating shafts 113 are staggered, and a belt conveyor 1211 is sleeved between two of the relatively arranged pulleys 1210 .

[0083] like Figure 3-4 As shown, when the first transfer component 11 transfers the parallel tiles 6 to the designated position and the color marking device 5 completes the color marking, the PLC controller instructs the multiple lifting cylinders 121 to start synchronously, and their telescopic ends extend and drive the second transfer bracket 122 to rise. Since the second transfer bracket 122 is arranged inside the first transfer bracket 111, and the second active rotating shaft 124 and the second driven rotating shaft 125 at both ends of the second transfer bracket 122 are sleeved with a second driven transmission belt 129, and the pulley 1210 of the second active rotating shaft 124 is staggered with the first transfer rotating shaft 113, during the rising process, the belt conveyor 1211 will gradually rise above the top surface of the first transfer rotating shaft 113, steadily lifting the marked parallel tiles 6 and separating them from the first transfer component 11.

[0084] Subsequently, the PLC controller activates the second transfer motor 123. The motor output drives the second driving shaft 124 to rotate via the second driving wheel 126 and the second driving transmission belt 127. The second driving shaft 124 then drives the second driven shaft 125 to rotate synchronously via the second driven wheel 128 and the second driven transmission belt 129. This causes the belt conveyor 1211 to rotate in the second conveying direction, transferring the marked parallel tiles 6 to the second conveying device 3, completing the transfer direction switch. When the tiles 6 completely leave the second transfer assembly 12, the lifting cylinder 121 retracts, driving the second transfer bracket 122 to descend and reset, awaiting the next transfer operation.

[0085] To further explain, the structure of the first conveying device 2 and the structure of the second conveying device 3 are consistent with the structure of the first transfer component 11.

[0086] Since the working principles of the first conveying device 2 and the second conveying device 3 are consistent with the working principle of the first transfer component 11, they are not described here in detail.

[0087] A control method is applied to a PLC controller, the PLC controller is used to control a detection device and a distributed coloring and marking device for tiles as described above, the detection device is installed at the input end of the first conveying device 2, and the detection device is used to detect the height difference between the upper surface of all tiles and the conveying surface of the first conveying device 2;

[0088] The control method comprises the following steps:

[0089] S1: The first conveying device 2 is started, and receives and conveys the tiles 6 produced in the parallel operation mode along the first conveying direction. The detection device synchronously detects the height difference between the upper surface of all tiles and the conveying surface of the first conveying device 2;

[0090] S2, the sorting device 4 is started, and with the maximum value of the height difference as a reference value, the sorting baffle 42 is raised to an appropriate height to block, positionally correct, and arrange the multiple tiles 6 conveyed by the first conveying device 2 to form a single parallel queue with aligned sides. After the preset sorting time t1, the sorting baffle 42 is lowered to allow the sorted parallel tiles 6 to smoothly enter the first transfer assembly 11;

[0091] S3, the first transfer assembly 11 is started, receiving and conveying the parallel tiles 6 along the first conveying direction. When the parallel tiles 6 reach the position where the coloring and marking devices 5 are located, the coloring time t2 is stopped, so that the single side edges of the parallel tiles 6 contact the coloring markers 51 in a one-to-one correspondence, and the multiple coloring markers 51 color the single side edges of the parallel tiles 6 in a one-to-one correspondence;

[0092] S4, the second transfer assembly 12 is started, the marked parallel tiles 6 are lifted steadily, and separated from the first transfer assembly 11 and the coloring marking device 5, the marked sides are left hanging to dry, and the tiles 6 are transferred to the second conveying device 3 along the second conveying direction;

[0093] S5, the second conveying device 3 is started, receives the tiles 6 along the second conveying direction, and conveys them to the back-end detection and packaging link;

[0094] S6. Repeat S1 to S5 to achieve continuous production.

[0095] like Figure 5As shown, since the sorting cylinder 41 mainly uses the hydraulic system to drive the piston movement through oil pressure to drive the sorting baffle 42 to rise and fall, the longer the hydraulic pump pressurizes the oil, the greater the lifting stroke of the sorting baffle 42. However, the greater the stroke, the longer the entire marking equipment stops, and the lower the efficiency. In order to improve production efficiency as much as possible, it is necessary to ensure that the tiles are fully and accurately blocked and aligned by the sorting baffle 42, and the lifting height can be reduced as much as possible. However, the specifications of the porcelain products fed from the first conveying device 2 may be different, and they may be deformed during the production process, and the thickness may also change. The height requirements for the lifting of the sorting baffle 42 are different for different tile thicknesses. Therefore, according to the thickness parameters of the tiles, adjustments are made, such as detecting the height difference between the upper surface of all the tiles fed and the conveying surface of the first conveying device 2, taking the maximum value of the height difference as a reference value, and adjusting the rising height of the sorting baffle 42 in the sorting device 4 according to the thickness parameters to ensure that the tiles can be blocked and aligned.

[0096] Therefore, in an optimized embodiment, a detection device is provided above the first conveying device 2 or at the feeding end (not shown in the drawing). The detection device may be an infrared sensor, a laser thickness sensor or the like for measuring the thickness parameters of the ceramic tiles, and the real-time parameters are sent to the PLC controller.

[0097] When the PLC controller receives the thickness parameters of all tiles measured by the detection device, it takes the maximum value of the height difference as the reference value, and adjusts the height difference between the top of the sorting baffle 42 and the conveying surface of the first conveying device 2 to be 2-3mm larger than the reference value. That is, the top of the sorting baffle 42 is slightly higher than the tile 6 with the maximum thickness, and it is sufficient to block the tile 6 with the maximum thickness. Because the sorting baffle 42 needs to be leveled, the transmission inertia of the first conveying device 2 needs to drive the tile 6 to hit the sorting baffle 42. It is possible that the tile 6 bounces up and cannot be blocked by the baffle. The rising height of the sorting baffle 42 is related to the thickness of the tile. In this way, while ensuring that the tiles are blocked, the baffle lifting stroke can be reduced as much as possible to improve efficiency.

[0098] In summary, this control method, through the addition of a PLC controller (not shown in the accompanying drawings) and a detection device (not shown in the accompanying drawings), enables the transfer device 1, the first conveying device 2, the second conveying device 3, and the coloring and marking device 5 to achieve fully automated coordinated operation based on preset parameters and fixed steps, ensuring the accurate positioning of parallel tiles 6 at the marking station. This not only reduces manual intervention and improves marking efficiency and accuracy, but also meets the needs of continuous production at the tile factory 6 and improves production efficiency. At the same time, combined with the preset correspondence between the coloring marker 51 and the production line, the side of the tile 6 is accurately bound to the production line, providing a reliable basis for subsequent quality traceability and solving the problem of difficulty in distinguishing the source of products after merging in the parallel operation mode.
