[0031] like Figure 1-11 As shown, a cigarette box laser automatic coding equipment includes a machine 1 and a controller. The machine 1 is provided with a feeding conveyor line 2, a paging feeding mechanism 3, a conveying mechanism 4, a laser coding mechanism 5 and a unloading mechanism 6 respectively connected to the controller.

[0032] During the processing, a whole stack of cigarette boxes to be processed is placed on the feeding conveyor line 2 by a robot or manually, and the whole stack of cigarette boxes is conveyed to the paging loading mechanism 3 by the feeding conveyor line 2; the paging loading mechanism 3 is then controlled to convey the cigarette boxes one by one to the transport mechanism 4 to complete the loading; then the cigarette boxes are conveyed to the processing position of the laser coding mechanism 5 by the transport mechanism 4, and the identification code is processed on the cigarette boxes by the laser coding mechanism 5; then the processed cigarette boxes are conveyed to the unloading mechanism 6 by the transport mechanism 4, and the processed products are stacked and coded by the unloading mechanism 6, and then the stacked cigarette boxes are sent out of the machine 1 to complete the unloading.

During specific processing, the feeding conveyor line 2 conveys the whole stack of cigarette boxes to the grabbing position of the material picking robot 31, and the whole stack of cigarette boxes is grabbed and placed on the material receiving assembly 33 by the material picking robot 31, and then the material receiving assembly 33 is controlled to place the whole stack of cigarette boxes on the inclined guide block 341, so that the whole stack of cigarette boxes is tilted; thereafter, under the action of gravity, one end of the cigarette box falls onto the loading conveyor line 35, and the loading conveyor line 35 moves the cigarette box in the direction of the paging limit block 342; due to the gap limitation between the paging limit block 342 and the loading conveyor line 35, only one cigarette box can pass through, so the whole stack of cigarette boxes passes through the gap between the paging limit block 342 and the loading conveyor line 35 one by one, so that the cigarette boxes are transported to the next workstation one by one through the loading conveyor line 35, thereby realizing the paging loading processing process for the whole stack of cigarette boxes.

By adjusting the height of the paging limit block 342, the gap between the paging limit block 342 and the feeding conveyor line 35 can be adjusted, so that it is suitable for the processing requirements of cigarette boxes of different thicknesses and improves versatility.

[0037] like Figure 3As shown, the paging guide assembly 34 also includes a guide roller 347, which is rotatably connected to the paging fixed frame 32, and is arranged directly above the feeding conveyor line 35, and can be connected to the cigarette boxes on the feeding conveyor line 35.

[0038] like Figure 4 As shown, the paging fixing frame 32 is provided with a guide mounting block 321, the guide mounting block 321 is connected to the paging fixing frame 32, one end of the oblique guide block 341 is hinged to the guide mounting block 321 by a screw, the oblique guide block 341 is provided with an arc-shaped limiting hole 348, the guide mounting block 321 is provided with a fixing hole, and the arc-shaped limiting hole 348 is fixedly connected to the fixing hole by a screw.

By adjusting the inclination angle of the oblique guide block 341, it can be applied to the processing requirements of cigarette boxes of different thicknesses, thereby improving versatility.

[0039] like Figure 4 As shown, the material receiving assembly 33 includes a first baffle 331 and a second baffle 332, and the first baffle 331 and the second baffle 332 are respectively connected to the paging fixed frame 32.

[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 picking robot 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 respectively controlled to retract, drive the first receiving plate 334 to retract to the first baffle 331, and the second receiving plate 336 to retract to the second baffle 332, and the two ends of the cigarette box are blocked by the first baffle 331 and the second baffle 332, so that the cigarette box is separated from the first receiving plate 334 and the second receiving plate 336, and falls onto the inclined guide block 341 under the action of the gravity of the cigarette box, so that the whole stack of cigarette boxes is tilted and placed on the inclined guide block 341. When the cigarette box falls onto the inclined guide block 341 and the loading is completed, 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 carry out the next round of loading processing.

The detection sensor 510 and the scanning terminal 59 are respectively located above the material transport conveyor line 42. During specific operation, when the material transport conveyor line 42 transports the cigarette box to be processed to the corresponding position of the detection sensor 510, the detection sensor 510 will detect the cigarette box, and then feedback the signal to the controller, and the controller controls the laser 53 to start working; through the detection sensor 510, the cigarette box on the material transport conveyor line 42 can be obtained in time, thereby improving the accuracy of control. When the material conveying line 42 conveys the processed cigarette box to the corresponding position of the scanning terminal 59, the scanning terminal 59 will scan the identification code on the cigarette box and feed back the scanning result to the controller. If the scanning code is correct, it means that the identification code on the cigarette box is processed properly. If the scanning code is wrong, it means that the identification code on the cigarette box is processed unqualified. The scanning terminal 59 can timely understand whether the identification code on the cigarette box is processed properly, thereby improving the processing yield rate.

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

[0051] Specifically, Fig. 9 As shown, the defective product rejection mechanism 7 includes a rejection mounting frame 71, which is fixedly connected to the material transport mounting frame 41, and is provided 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, and the rejection cylinder 72 can drive the rejection block 73 to rotate and swing, thereby driving the end of the rejection block 73 away from the rejection cylinder 72 to move in a direction close to or away from the material transport conveyor line 42. A defective product discharge port 74 is provided on the machine 1 at a position corresponding to the rejection block 73; before processing, a collection box can be placed on the defective product discharge port 74. During the processing, if the scanning terminal 59 scans an incorrect cigarette box identification code on the material conveyor line 42, a feedback signal is given to the controller; the controller controls the rejection cylinder 72 to work, driving the rejection block 73 to rotate and swing, so that the rejection block 73 moves away from the end of the rejection cylinder 72 toward the direction close to the material conveyor line 42, until the rejection block 73 squeezes the defective products on the material conveyor line 42 out of the material conveyor line 42. After being squeezed out of the material conveyor line 42, the defective products will fall to the defective product outlet 74, and finally fall into the collection box for unified treatment.

[0052] like Fig.10 As shown, the unloading mechanism 6 includes an unloading manipulator 61 and an unloading conveyor line 62. The unloading manipulator 61 is connected to the material transport mechanism 4 and the unloading conveyor line 62 respectively. The machine 1 is provided with a coding and guiding mechanism 8, which is connected to the unloading manipulator 61 and is used to correct the stacking of cigarette boxes on the unloading manipulator 61. During the processing, the material transport conveyor line 42 transports the cigarette boxes with qualified coding to the unloading manipulator 61, and then the cigarette boxes are corrected and stacked by the coding and guiding mechanism 8. After that, the unloading manipulator 61 places the stacked cigarette boxes on the unloading conveyor line 62, and then the unloading conveyor line 62 sends the whole stack of cigarette boxes with qualified coding out of the machine 1 to complete the unloading.

[0053] like Fig.11 As shown, the code material guiding mechanism 8 includes a guiding motor 81 and a guiding rod 82, the guiding rod 82 is slidably connected to the machine 1, a push block 83 is provided on the guiding rod 82, the guiding motor 81 is fixedly installed on the machine 1, a guiding drive wheel 84 is provided on the output end of the guiding motor 81, a guiding drive shaft 85 is provided on the guiding drive wheel 84, the guiding drive shaft 85 is rotatably limitedly connected to the machine 1, a guiding crankshaft 86 is provided at one end of the guiding drive shaft 85 away from the guiding drive wheel 84, a transmission shaft 87 is provided at the other end of the guiding crankshaft 86, both ends of the transmission shaft 87 are respectively hinged to the guiding rod 82 and the guiding crankshaft 86, the guiding drive wheel 84 can drive the guiding crankshaft 86 to rotate, and then drive the guiding rod 82 to slide laterally. During specific operation, the discharging conveyor line 62 conveys the processed products to the unloading robot 61; then, by controlling the work of the guiding motor 81, the guiding drive wheel 84 is driven to rotate, and the guiding drive shaft 85 and the guiding crankshaft 86 are driven to rotate synchronously. The guiding crankshaft 86 will drive the guiding rod 82 to slide on the machine 1, thereby driving the push block 83 to reciprocate laterally. The push block 83 will connect with the side wall of the cigarette box on the unloading robot 61, and then push the cigarette box to the preset position of the unloading robot 61; through the reciprocating lateral movement of the push block 83, the cigarette boxes can be pushed to be stacked neatly on the unloading robot 61, and then the unloading robot 61 will place the whole stack of cigarette boxes on the discharging conveyor line 62, and then send them out of the machine 1 through the discharging conveyor line 62 to complete the unloading.

[0054] Working principle:

[0055] First, a whole stack of cigarette boxes to be processed is placed on the feeding conveyor line 2 by a robot or manually, and the whole stack of cigarette boxes is transported to the material taking robot 31 by the feeding conveyor 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 material taking robot 31; then the first receiving cylinder 333 and the second receiving cylinder 335 are controlled to work, drive the first receiving plate 334 and the second receiving plate 336 to move away from each other, and push the whole stack of cigarette boxes away from the first receiving plate 334 and the second receiving plate 336 by the first baffle plate 331 and the second baffle plate 332 , causing the cigarette box to fall onto the inclined guide block 341, and then one end of the cigarette box falls onto the feeding conveyor line 35 under the action of gravity, and then the feeding conveyor line 35 is controlled to convey the cigarette box in the direction of the paging limit block 342; due to the gap limitation between the paging limit block 342 and the feeding conveyor line 35, only one cigarette box can pass through, so the whole stack of cigarette boxes passes through the gap between the paging limit block 342 and the feeding conveyor line 35 one by one, so that the cigarette boxes are transported one by one to the material conveyor line 42 through the feeding conveyor line 35, completing the paging and feeding process of the cigarette boxes.

[0056] The cigarette box enters the material conveyor line 42, and by controlling the material conveyor line 42 to work, the cigarette box is driven to move in the direction of the laser coding mechanism 5. When the cigarette box passes the corresponding position of the detection sensor 510, the detection sensor 510 will detect the cigarette box, and then feedback the signal to the controller, and the controller will control the laser 53 to start working; the corresponding identification code is processed on the cigarette box to be processed through the laser coding terminal 54. After that, the material conveyor line 42 will transport the processed product to the corresponding position of the scanning terminal 59, and the scanning terminal 59 will scan the identification code on the cigarette box; and the scanning result will be fed back to the controller. If the code is scanned correctly, it means that the identification code on the cigarette box is processed qualifiedly, and if the code is scanned incorrectly, it means that the identification code on the cigarette box is processed unqualifiedly.

[0057] The qualified products scanned by the scanning dock 59 are transported to the unloading robot 61 through the material transport conveyor line 42, and then the qualified cigarette boxes are corrected and stacked by the code guiding mechanism 8; thereafter, the whole stack of cigarette boxes is placed on the discharging conveyor line 62 by the unloading robot 61, and the whole stack of qualified cigarette boxes is sent out of the machine 1 by the discharging conveyor line 62, and the unloading is completed.

[0058] When the scanning terminal 59 scans an error in the cigarette box identification code on the material conveyor line 42, a feedback signal is sent to the controller; the controller controls the defective product removal mechanism 7 to work, remove the defective products from the material conveyor line 42, make them fall out of the machine 1, and then process them uniformly.

[0059] The above-mentioned specific implementation is a preferred implementation of the present invention, and is not intended to limit the specific implementation scope of the present invention. The scope of the present invention includes but is not limited to this specific implementation. All equivalent changes made in accordance with the present invention are within the protection scope of the present invention.
