[0031] like Figures 1-11 As shown, an automatic laser coding device for cigarette boxes includes a machine base 1 and a controller. The machine base 1 is equipped with a feeding conveyor line 2, a paging and loading mechanism 3, a conveying mechanism 4, a laser coding mechanism 5, and a unloading mechanism 6, all connected to the controller. One end of the feeding conveyor line 2 is connected to the paging and loading mechanism 3, used to convey stacks of cigarette boxes onto the paging and loading mechanism 3. The paging and loading mechanism 3 is connected to both the feeding conveyor line 2 and the conveying mechanism 4, used to receive stacks of cigarette boxes from the feeding conveyor line 2 and paging and loading the cigarette boxes one by one onto the conveying mechanism 4. The conveying mechanism 4 is connected to the paging and loading mechanism 3, the laser coding mechanism 5, and the unloading mechanism 6, used to convey cigarette boxes one by one onto the laser coding mechanism 5 and deliver the processed products to the unloading mechanism 6. The laser coding mechanism 5 is used to code the cigarette boxes on the conveying mechanism 4, and the unloading mechanism 6 is used to receive the processed cigarette boxes on the conveying mechanism 4 and stack and deliver the processed cigarette boxes out of the machine base 1.

[0032] In the processing process, the whole stack of to-be-processed cigarette boxes is placed on the feeding conveying line 2 by a mechanical hand or manually, and the whole stack of cigarette boxes is conveyed to the page-by-page feeding mechanism 3 through the feeding conveying line 2; then the page-by-page feeding mechanism 3 is controlled to convey the cigarette boxes one by one to the material conveying mechanism 4 to complete the feeding; then the material conveying mechanism 4 conveys the cigarette boxes to the processing position of the laser coding mechanism 5, and the laser coding mechanism 5 processes the identification code on the cigarette boxes; then the material conveying mechanism 4 conveys the processed cigarette boxes to the discharging mechanism 6, the discharging mechanism 6 stacks the processed products, and then the stacked cigarette boxes are sent out of the machine table 1, and the discharging is completed.

[0033] The cigarette box laser automatic coding equipment can feed the whole stack of cigarette boxes, realize automatic page-by-page feeding through the page-by-page feeding mechanism 3, and does not need manual page-by-page; and in the processing process, automatic material conveying, coding and discharging are adopted, and manual participation is not needed, which improves the automation degree of the equipment, and further improves the processing efficiency of the cigarette box coding, and can meet the processing requirements of high quality and high efficiency.

[0034] As shown in Figures 3-6 The page-by-page feeding mechanism 3 includes a material taking mechanical hand 31 and a page-by-page fixing frame 32 installed on the machine table 1 respectively, the material taking mechanical hand 31 is connected with the controller, the page-by-page fixing frame 32 is provided with a material receiving assembly 33, a page-by-page guiding assembly 34 and a feeding conveying line 35, the material receiving assembly 33 and the feeding conveying line 35 are connected with the controller respectively, the material taking mechanical hand 31 is connected with the feeding conveying line 2 and the material receiving assembly 33 respectively, and is used for placing the whole stack of cigarette boxes conveyed from the feeding conveying line 2 on the material receiving assembly 33, the material receiving assembly 33 is used for placing the whole stack of cigarette boxes on the page-by-page guiding assembly 34, the page-by-page guiding assembly 34 is connected with the feeding conveying line 35, the page-by-page guiding assembly 34 is used for moving and conveying the whole stack of cigarette boxes one by one to the feeding conveying line 35, and the feeding conveying line 35 is used for conveying the cigarette boxes to the material conveying mechanism 4.

[0035] Specifically, the page guiding assembly 34 comprises an inclined guiding block 341 and a page limiting block 342. The inclined guiding block 341 is obliquely arranged on the page fixing frame 32 and is adjustably limited with the page fixing frame 32. The page limiting block 342 is connected with the page fixing frame 32 and is arranged on one side of the inclined guiding block 341. The page limiting block 342 is arranged above the feeding conveying line 35. The gap between the page limiting block 342 and the feeding conveying line 35 is greater than the thickness of one cigarette case and less than the thickness of two cigarette cases, so that the cigarette case can only pass through the gap between the page limiting block 342 and the feeding conveying line 35 one by one. In the specific processing, the feeding conveying line 2 conveys the whole stack of cigarette cases to the grabbing position of the grabbing manipulator 31. The grabbing manipulator 31 grabs and places the whole stack of cigarette cases on the receiving assembly 33. Then, the receiving assembly 33 places the whole stack of cigarette cases on the inclined guiding block 341, so that the whole stack of cigarette cases is inclined. Then, under the action of gravity, one end of the cigarette case falls on the feeding conveying line 35. The feeding conveying line 35 moves the cigarette case to the direction of the page limiting block 342. Because the gap between the page limiting block 342 and the feeding conveying line 35 limits that only one cigarette case can pass through, the whole stack of cigarette cases passes through the gap between the page limiting block 342 and the feeding conveying line 35 one by one, so that the feeding conveying line 35 conveys the cigarette cases one by one to the next station, realizing the page feeding and processing of the whole stack of cigarette cases.

[0036] As shown in Figure 5 In order to be suitable for products with different thicknesses, the first adjusting assembly for adjusting the height of the page limiting block 342 is arranged on the page fixing frame 32. The first adjusting assembly comprises an adjusting fixed seat 343 and an adjusting lifting seat 344. The adjusting fixed seat 343 is connected with the page fixing frame 32. The page limiting block 342 is fixedly connected with the adjusting lifting seat 344. The adjusting lifting seat 344 is provided with a rotatable first adjusting lead screw 345. The first adjusting lead screw 345 passes through the adjusting fixed seat 343 and is slidably connected with the adjusting fixed seat 343. One end of the first adjusting lead screw 345 is provided with a page adjusting knob 346. When it is necessary to adjust the height of the page limiting block 342, the page adjusting knob 346 is rotated to drive the first adjusting lead screw 345 to rotate. The first adjusting lead screw 345 slides up and down on the adjusting fixed seat 343, thereby driving the adjusting lifting seat 344 and the page limiting block 342 to move up and down, so as to adjust the height of the page limiting block 342. By adjusting the height of the page limiting block 342, the gap between the page limiting block 342 and the feeding conveying line 35 can be adjusted, so as to be suitable for the processing requirements of cigarette cases with different thicknesses and improve the universality.

[0037] As shown in Figure 3As shown, the page guiding assembly 34 further comprises a guiding roller 347 rotatably connected with the page fixing frame 32, which is arranged above the feeding conveying line 35 and can be connected with the cigarette box on the feeding conveying line 35. The guiding roller 347 is located on the side of the page limiting block 342 away from the inclined guiding block 341. The guiding roller 347 can press and cover the cigarette box flowing out from the gap between the page limiting block 342 and the feeding conveying line 35, so as to press and cover the cigarette box flat. Then, the cigarette box is conveyed to the material conveying mechanism 4 by the feeding conveying line 35, so that the subsequent laser coding mechanism 5 can code the cigarette box, thereby improving the yield of processing.

[0038] As shown in Figure 4 The page fixing frame 32 is provided with a guiding mounting block 321 connected with the page fixing frame 32. One end of the inclined guiding block 341 is hingedly connected with the guiding mounting block 321 by a screw. The inclined guiding block 341 is provided with an arc-shaped limiting hole 348, and the guiding mounting block 321 is provided with a fixing hole. The arc-shaped limiting hole 348 and the fixing hole are fixedly connected by a screw. In this case, the arc-shaped limiting hole 348 and the fixing hole are fixedly connected by the screw, so that the inclined guiding block 341 is fixedly connected with the guiding mounting block 321. When it is necessary to adjust the inclination angle of the inclined guiding block 341, the connecting screw of the arc-shaped limiting hole 348 and the fixing hole can be loosened. In this way, the inclined guiding block 341 can be rotated and swung along the hinged end. After being adjusted to a suitable position, the connecting screw of the arc-shaped limiting hole 348 and the fixing hole is tightened again. By adjusting the inclination angle of the inclined guiding block 341, it can be applied to the processing requirements of cigarette boxes with different thicknesses, thereby improving the versatility.

[0039] As shown in Figure 4 The material receiving assembly 33 comprises a first baffle 331 and a second baffle 332 connected with the page fixing frame 32, respectively. The first baffle 331 is provided with a first material receiving cylinder 333, and the output end of the first material receiving cylinder 333 is provided with a first material receiving plate 334. The first material receiving cylinder 333 can drive the first material receiving plate 334 to extend into or out of the first baffle 331. The second baffle 332 is provided with a second material receiving cylinder 335, and the output end of the second material receiving cylinder 335 is provided with a second material receiving plate 336. The second material receiving plate 336 is at the same horizontal height as the first material receiving plate 334. The second material receiving cylinder 335 can drive the second material receiving plate 336 to extend into or out of the second baffle 332.

[0040] In the initial state, the first receiving cylinder 333 and the second receiving cylinder 335 are in the extended state respectively, so that the first receiving plate 334 extends out of the first baffle 331 and the second receiving plate 336 extends out of the second baffle 332. During processing, the material taking manipulator 31 places the whole stack of cigarette boxes on the first receiving plate 334 and the second receiving plate 336; then the first receiving cylinder 333 and the second receiving cylinder 335 are controlled to retract respectively, driving the first receiving plate 334 to retract into the first baffle 331 and the second receiving plate 336 to retract into the second baffle 332, so that the two ends of the cigarette box are blocked by the first baffle 331 and the second baffle 332, and the cigarette box is separated from the first receiving plate 334 and the second receiving plate 336 and falls on the inclined guide block 341 under the action of gravity, so as to place the whole stack of cigarette boxes on the inclined guide block 341. After the cigarette box is placed on the inclined guide block 341, the first receiving cylinder 333 and the second receiving cylinder 335 are controlled to extend, so that the first receiving plate 334 extends out of the first baffle 331 again and the second receiving plate 336 extends out of the second baffle 332 again, so as to process the next round of feeding.

[0041] In order to adapt to the processing requirements of cigarette boxes of different sizes, the second adjusting assembly 36 for driving the second baffle 332 to move is arranged on the page fixing frame 32. The second adjusting assembly 36 can drive the second baffle 332 to move towards or away from the first baffle 331, so as to adjust the distance between the second baffle 332 and the first baffle 331 and adapt to the processing of cigarette boxes of different sizes.

[0042] Specifically, as shown in Figure 4 the second adjusting assembly 36 includes an adjusting motor 361 connected with the page fixing frame 32. The output end of the adjusting motor 361 is provided with a second adjusting screw 362. The second adjusting screw 362 is slidably provided with an adjusting sliding block 363. The second baffle 332 is connected with the adjusting sliding block 363. When adjustment is needed, the adjusting motor 361 is controlled to work, driving the second adjusting screw 362 to rotate and in turn driving the adjusting sliding block 363 to slide on the second adjusting screw 362. The adjusting sliding block 363 drives the second baffle 332 to move synchronously, so that the second baffle 332 moves towards or away from the first baffle 331, adjusting the distance between the second baffle 332 and the first baffle 331.

[0043] In order to facilitate adjustment, a lifting fixing seat 364 is arranged on the adjusting slider 363, a lifting cylinder 365 is arranged on the lifting fixing seat 364, the second baffle 332 is fixedly connected with the output end of the lifting cylinder 365, and the lifting cylinder 365 can drive the second baffle 332 to move up and down. In the initial state, the lifting cylinder 365 is in the extended state, so that the second baffle 332 abuts against the page fixing frame 32, the second baffle 332 is limited and fixed with the page fixing frame 32, and the stability of the lifting structure is improved. When it is necessary to adjust the distance between the first baffle 331 and the second baffle 332, the lifting cylinder 365 is first controlled to retract, the second baffle 332 is driven to move up, the second baffle 332 is separated from the page fixing frame 32; then the adjusting motor 361 is controlled to work, the second baffle 332 is driven to move towards or away from the first baffle 331, and after being adjusted to the appropriate position, the adjusting motor 361 is controlled to stop working, the lifting cylinder 365 is controlled to extend, the second baffle 332 is driven to move down, and the second baffle 332 abuts against the page fixing frame 32 again.

[0044] As shown in Figure 6 The taking manipulator 31 includes a manipulator mounting frame 311, the manipulator mounting frame 311 is slidingly connected with the machine table 1, the machine table 1 is provided with a manipulator transverse moving module 312 for driving the manipulator mounting frame 311 to slide transversely, the manipulator mounting frame 311 is provided with a manipulator lifting module 313, the output end of the manipulator lifting module 313 is provided with a taking plate 314, and the manipulator lifting module 313 can drive the taking plate 314 to move up and down. In the initial state, the taking plate 314 is connected with the feeding conveying line 2, and the feeding conveying line 2 can convey the whole stack of cigarette boxes to the taking plate 314; after the whole stack of cigarette boxes is conveyed to the taking plate 314, the manipulator transverse moving module 312 is first controlled to drive the manipulator mounting frame 311 to move the taking plate 314 transversely, so that the taking plate 314 moves to the position directly above the receiving assembly 33, and then the manipulator lifting module 313 is controlled to drive the taking plate 314 to move down until the taking plate 314 passes through the gap between the first receiving plate 334 and the second receiving plate 336; in this process, the whole stack of cigarette boxes on the taking plate 314 abuts against the first receiving plate 334 and the second receiving plate 336, and is lifted by the first receiving plate 334 and the second receiving plate 336, so as to be separated from the taking plate 314; then the manipulator transverse moving module 312 is controlled to drive the manipulator mounting frame 311 to continue to move the taking plate 314 backward, so that the taking plate 314 moves away from the receiving structure; after one round of taking is completed, the taking manipulator 31 is controlled to reset.

[0045] In the embodiment, the manipulator transverse moving module 312 and the manipulator lifting module 313 both adopt a motor and screw structure; in other embodiments, the manipulator transverse moving module 312 and the manipulator lifting module 313 can also adopt other mechanical structures capable of driving linear motion, for example, a cylinder structure.

[0046] As shown in Figure 7 , the material conveying mechanism 4 comprises a material conveying mounting frame 41 fixedly connected with the machine table 1, and a material conveying line 42 and a guide and pressing mechanism 43 are arranged on the material conveying mounting frame 41. The material conveying line 35 can convey the cigarette boxes to the material conveying line 42. The material conveying line 42 can adopt any existing motor pulley structure, and the motor drives the conveyor belt to move, thereby driving the cigarette boxes to move from the material conveying line 35 to the direction close to the discharging mechanism 6. The guide and pressing mechanism 43 is arranged above the material conveying line 42, and is used for pressing and limiting the cigarette boxes on the material conveying line 42, so as to prevent the cigarette boxes from deviating and make them be stably conveyed to the processing position of the laser coding mechanism 5, thereby improving the processing stability.

[0047] As shown in Figure 8 , the laser coding mechanism 5 comprises a coding fixed frame 51 slidably and limitingly connected with the machine table 1, and a coding horizontal movement module 52 is arranged on the coding fixed frame 51. A laser 53 is arranged on the output end of the coding horizontal movement module 52, and the coding horizontal movement module 52 can drive the laser 53 to move horizontally, so as to be suitable for different types of cigarette box processing requirements. A laser coding head 54 is arranged on the laser 53, and the laser coding head 54 is arranged above the material conveying mechanism 4. The laser emitted by the laser coding head 54 can irradiate the cigarette boxes on the material conveying mechanism 4. In specific processing, the cigarette boxes to be processed are conveyed to the lower side of the laser coding head 54 through the material conveying line 42. The laser 53 is controlled to work, so that the corresponding identification code is processed on the cigarette boxes to be processed through the laser coding head 54. The processed products are conveyed to the discharging mechanism 6 through the material conveying line 42.

[0048] The machine table 1 is provided with a coding adjustment sliding rail 55, and a coding adjustment sliding block 56 is arranged at the corresponding position of the coding adjustment sliding rail 55 on the coding fixed frame 51. A coding adjustment knob 57 is arranged on the coding adjustment sliding block 56, and the coding adjustment knob 57 is detachably and limitingly connected with the coding adjustment sliding rail 55. The coding fixed frame 51 can be slid on the coding adjustment sliding rail 55 by loosening the coding adjustment knob 57, so as to adjust the installation position of the laser 53, thereby being suitable for processing different types of product requirements. Under normal circumstances, the coding adjustment knob 57 is fixedly connected with the coding adjustment sliding rail 55, so that the coding fixed frame 51 is connected and limited with the machine table 1. When the position of the laser 53 needs to be adjusted, the coding adjustment knob 57 is separated from the coding adjustment sliding rail 55 by loosening the coding adjustment knob 57. Then the laser 53 is driven to move synchronously by pushing the coding fixed frame 51. After being adjusted to the appropriate position, the coding adjustment knob 57 is tightened again.

[0049] As shown in Figure 8As shown, the laser 53 is equipped with an identification mounting bracket 58, which in turn is equipped with a scanning dock 59 and a detection sensor 510. The detection sensor 510 is used to retrieve cigarette boxes on the conveying mechanism 4, and the scanning dock 59 is used to scan the identification code on the cigarette boxes on the conveying mechanism 4. The detection sensor 510 and the scanning dock 59 are located above the conveying line 42. During operation, when the conveying line 42 transports the cigarette boxes to be processed to the corresponding position of the detection sensor 510, the detection sensor 510 will detect the cigarette box and then send a feedback signal to the controller. The controller then controls the laser 53 to start working. By using the detection sensor 510, the cigarette boxes on the conveying line 42 can be acquired in a timely manner, thereby improving the accuracy of control. After the material conveyor line 42 transports the processed cigarette boxes to the corresponding position of the scanning dock 59, the scanning dock 59 scans the identification code on the cigarette box and feeds the scanning result back to the controller. If the scan is correct, it means that the identification code on the cigarette box has been processed successfully; if the scan is incorrect, it means that the identification code on the cigarette box has not been processed successfully. The scanning dock 59 allows for timely monitoring of whether the identification code on the cigarette box has been processed successfully, thus improving the yield rate.

[0050] In this embodiment, a defective product rejection mechanism 7 is also provided on the material conveying installation frame 41. The defective product rejection mechanism 7 is located on the side of the sweeping dock 59 away from the laser-marking dock 54. It is used to remove defective products from the material conveying line 42, thereby ensuring that the products transported to the unloading mechanism 6 are qualified products, reducing sorting steps and further saving labor.

[0051] Specifically, such as Figure 9 As shown, the defective product rejection mechanism 7 includes a rejection mounting frame 71, which is fixedly connected to the material conveying mounting frame 41. The rejection mounting frame 71 is equipped with a rejection cylinder 72 and a rejection block 73. The rejection cylinder 72 is hinged to the rejection mounting frame 71, and the middle part of the rejection block 73 is hinged to the rejection mounting frame 71. The output end of the rejection cylinder 72 is hinged to one end of the rejection block 73. The rejection cylinder 72 can drive the rejection block 73 to rotate and swing, thereby causing the end of the rejection block 73 away from the rejection cylinder 72 to move towards or away from the material conveying line 42. A defective product outlet 74 is provided on the machine base 1 at a position corresponding to the rejection block 73; before processing, a collection box can be placed on the defective product outlet 74. During processing, if the scanning dock 59 detects an error in the identification code of the cigarette box on the conveyor line 42, it sends a feedback signal to the controller. The controller then controls the rejection cylinder 72 to work, driving the rejection block 73 to rotate and swing, so that the end of the rejection block 73 away from the rejection cylinder 72 moves towards the conveyor line 42 until the rejection block 73 squeezes the defective products out of the conveyor line 42. After being squeezed out of the conveyor line 42, the defective products will fall into the defective product outlet 74 and finally fall into the collection box for unified processing.

During processing, the material conveying line 42 conveys the qualified cartons to the unloading manipulator 61, and then the stacking guide mechanism 8 guides the stacking of the cartons, and then the unloading manipulator 61 places the stacked cartons on the unloading conveying line 62, and then the unloading conveying line 62 sends out the qualified whole stack of cartons from the machine table 1 to complete the unloading.

[0053] As Figure 11 shown, the stacking guide mechanism 8 includes a guide motor 81 and a guide rod 82, the guide rod 82 is slidably connected with the machine table 1, the guide rod 82 is provided with a push block 83, the guide motor 81 is fixedly installed on the machine table 1, the output end of the guide motor 81 is provided with a guide driving wheel 84, the guide driving wheel 84 is provided with a guide driving shaft 85, the guide driving shaft 85 is rotatably and limitingly connected with the machine table 1, the end of the guide driving shaft 85 away from the guide driving wheel 84 is provided with a guide crankshaft 86, the other end of the guide crankshaft 86 is provided with a transmission shaft 87, the two ends of the transmission shaft 87 are hingedly connected with the guide rod 82 and the guide crankshaft 86 respectively, the guide driving wheel 84 can drive the guide crankshaft 86 to rotate, and then drive the guide rod 82 to slide transversely. Specifically, the unloading conveying line 62 conveys the processed products to the unloading manipulator 61; then the guide motor 81 is controlled to work, the guide driving wheel 84 is driven to rotate, the guide driving shaft 85 and the guide crankshaft 86 are synchronously rotated, the guide crankshaft 86 drives the guide rod 82 to slide on the machine table 1, so as to drive the push block 83 to reciprocate transversely, the push block 83 will be in contact with the side wall of the carton on the unloading manipulator 61, and then push the carton to the preset position of the unloading manipulator 61; through the reciprocating transverse movement of the push block 83, the carton can be pushed to be neatly stacked on the unloading manipulator 61, and then the whole stack of cartons is placed on the unloading conveying line 62 by the unloading manipulator 61, and then sent out from the machine table 1 by the unloading conveying line 62 to complete the unloading.

[0054] Working principle:

[0055] Firstly, the whole stack of cigarette boxes to be processed is placed on the feeding conveying line 2 by a mechanical hand or manually, and then the whole stack of cigarette boxes is conveyed to the taking mechanical hand 31 by the feeding conveying line 2, and then the whole stack of cigarette boxes is placed on the first receiving plate 334 and the second receiving plate 336 by the taking mechanical hand 31; then the first receiving cylinder 333 and the second receiving cylinder 335 are controlled to work, the first receiving plate 334 and the second receiving plate 336 are driven to move away from each other, the whole stack of cigarette boxes is pushed away from the first receiving plate 334 and the second receiving plate 336 by the first baffle 331 and the second baffle 332, so that the cigarette boxes fall on the inclined guide block 341, and then one end of the cigarette boxes falls on the feeding conveying line 35 under the action of gravity, and then the feeding conveying line 35 is controlled to convey the cigarette boxes to the direction of the page limiting block 342; because the gap between the page limiting block 342 and the feeding conveying line 35 is limited, only one cigarette box can pass through, so that one by one of the whole stack of cigarette boxes passes through the gap between the page limiting block 342 and the feeding conveying line 35, and then the cigarette boxes are conveyed one by one on the feeding conveying line 35 to the material conveying line 42, and the page feeding process of the cigarette boxes is completed.

[0056] When the cigarette boxes enter the material conveying line 42, the material conveying line 42 is controlled to work, and the cigarette boxes are driven to move to the direction of the laser coding mechanism 5, and when the cigarette boxes pass through the corresponding position of the detection sensor 510, the detection sensor 510 detects the cigarette boxes, and then feeds back a signal to the controller, and the controller controls the laser 53 to start working; and the laser coding head 54 processes the corresponding identification code on the cigarette boxes to be processed. Then the material conveying line 42 conveys the processed products to the corresponding position of the code scanning head 59, and the code scanning head 59 scans the identification code on the cigarette boxes; and feeds back the scanning result to the controller, if the code scanning is correct, it means that the identification code on the cigarette boxes is processed qualified, if the code scanning is incorrect, it means that the identification code on the cigarette boxes is processed unqualified.

[0057] The products scanned by the code scanning head 59 are conveyed to the unloading mechanical hand 61 by the material conveying line 42, and then the qualified cigarette boxes are stacked and placed by the code material guide mechanism 8; then the whole stack of cigarette boxes is placed on the discharging conveying line 62 by the unloading mechanical hand 61, and the whole stack of qualified cigarette boxes is discharged from the machine table 1 by the discharging conveying line 62, and the unloading is completed.

[0058] When the code scanning head 59 scans the identification code of the cigarette boxes on the material conveying line 42, a signal is fed back to the controller; and the controller controls the defective product removing mechanism 7 to work, and removes the defective product from the material conveying line 42, so that it falls out of the machine table 1, and then it is processed uniformly.
