[0030] Example 1

[0031] Reference Figure 1-2 The No. 1 engineering code printing system of the case packing machine includes a conveying device A and a control device 5, and a cigarette box side device 1, a cigarette box specification detection device 2 and a coding device group arranged in sequence along the conveying direction of the conveying device A.

[0032] The conveying device A comprises a roller conveyor belt, and the cigarette box moves forward by the rotation of the roller.

[0033] The cigarette box edge device 1 comprises a pusher, a push sensor and an in-place sensor 12 located on the pusher, and the pusher and the in-place sensor 12 are arranged opposite to each other on both sides of the conveying device A. When the push sensor detects a cigarette box, the pusher pushes the cigarette box to the side of the in-place sensor 12, so that all cigarette boxes are close to the side of the in-place sensor 12 and are located at the same edge position, so as to facilitate the subsequent judgment of the specifications of the cigarette box according to the length of the cigarette box (the axial direction of the roller of the conveying device A); when the in-place sensor 12 detects the cigarette box, the pusher is retracted.

[0034] The cigarette box specification detection device 2 includes a plurality of specification judgment sensors 21 located above the conveying device A, and the connecting line of the plurality of specification judgment sensors 21 is perpendicular to the travel direction of the conveying device A, that is, the connecting line is parallel to the axial direction of the roller. Different numbers of response of specification detection sensors correspond to different specifications of cigarette boxes, that is, the specifications of the cigarette boxes are judged according to the length of the cigarette boxes. Specifically, when the cigarette box passes through the cigarette box specification detection device 2, only the specification judgment sensor 21 closest to the in-place sensor 12 responds (detects the cigarette box), which is the cigarette box with the shortest length, and only the specification judgment sensor 21 closest to the in-place sensor 12 and the in-place sensor 12 adjacent to it respond, which is the second shortest cigarette box in length, and so on. When all specification judgment sensors 21 respond, it is the cigarette box with the longest length.

[0035] The coding device group includes a plurality of coding devices arranged in sequence (along the conveying direction), and the number of coding devices is the same as the number of specification judgment sensors 21. The number of the two depends on how many cigarette boxes of different specifications need to be coded in actual production. Different cigarette box specifications trigger different coding devices to work, that is, a cigarette box of one specification only triggers one coding device corresponding to it to work.

[0036] Each coding device includes a coding machine and a barcode scanner, and a sensor group, which are sequentially arranged above the conveying device A. The coding machine includes a paper feeding component and a labeling component. The sensor group includes a paper feeding sensor, a pressure sensor, and a barcode scanning sensor, which are sequentially arranged on the side of the conveying device A. The paper feeding sensor and the pressure sensor are both located on the left side of the barcode scanner. The barcode scanning sensor is located between the coding machine and the barcode scanner. When the paper feeding sensor detects a cigarette box, the paper feeding component feeds paper. When the pressure sensor detects a cigarette box, the pressure plate of the labeling component presses down to paste the No. 1 engineering code on the cigarette box. When the barcode scanning sensor detects a cigarette box, the barcode scanner scans the No. 1 engineering code and uploads the scanned information to the control device 5.

[0037] In this embodiment,

[0038] The number of specification judgment sensors 21 is two. The cigarette box specification detection device 2 also includes an H-shaped bracket 23 and two specification verification sensors 22 located on the right side of the specification judgment sensor 21 and corresponding to the position. The connecting line of the two specification judgment sensors 21 is parallel to the connecting line of the two specification verification sensors 22. The vertical distance between the specification judgment sensor 21 and the specification verification sensor 22 is less than the width of the cigarette box (the direction of travel of the conveying device A). In this embodiment, through the installation method of four groups of two, that is, one judgment group (two specification judgment sensors 21) and one verification group (two specification verification sensors 22), the judgment group first judges the specifications of the cigarette box, and then the verification group verifies. Compared with the installation method of two groups (one specification judgment sensor 21 and one specification verification sensor 22) and three groups (two specification judgment sensors 21 and one specification verification sensor 22), the installation method of four groups of two can not only ensure high recognition accuracy (recognition accuracy ≥ 99.98%) but also maintain its stability (stability ≥ 99.98%). The specification judgment sensor 21 and the specification verification sensor 22 are both installed on the H-shaped bracket 23, that is, located above the conveying device A. Compared with the side installation or the top and side joint installation, the top installation method can not only ensure high detection accuracy (detection accuracy ≥ 99.98%) but also facilitate debugging and replacement (debugging and replacement time ≤ 60s). Since the length of the diamond soft lotus is less than the length of the diamond soft green, when the specification judgment sensor 21 and the specification verification sensor 22 located only on one side of the in-place sensor 12 detect the cigarette box, the cigarette box specification is determined to be a small cigarette box (diamond soft lotus), and when the two specification judgment sensors 21 and the two specification verification sensors 22 both detect the cigarette box, the cigarette box specification is determined to be a large cigarette box (diamond soft green).

[0039] The number of coding devices in the coding device group is two, namely, coding device I3 and coding device II4, which are arranged in sequence. Coding device I3 includes coding bracket I31, coding machine I32 installed on coding bracket I31, and code scanner I33, and code scanner I33 is located on the right side of coding machine I32. Coding device II4 includes coding bracket II41, coding machine II42 installed on coding bracket II41, and code scanner II43, and code scanner II43 is located on the right side of coding machine II42.

[0040] Among them, both the coding machine I32 and the coding machine II42 include a paper feeding component and a pneumatic labeling component, and the maximum distance from the pneumatic labeling component of the coding machine I32 or the coding machine II42 to the cigarette box is ≤759mm.

[0041] A paper feed sensor Ⅰ34 and a downward pressure sensor Ⅰ35 are sequentially arranged between the cigarette box specification detection device 2 and the coding device Ⅰ3. Both the paper feed sensor Ⅰ34 and the downward pressure sensor Ⅰ35 are arranged on the side of the conveying device A. When the paper feed sensor Ⅰ34 detects the cigarette box, the paper feed component of the coding machine Ⅰ32 feeds paper; when the downward pressure sensor Ⅰ35 detects the cigarette box, the pressure plate of the pneumatic labeling component of the coding machine Ⅰ32 presses down to paste the No. 1 engineering code on the cigarette box. A code scanning sensor Ⅰ36, a paper feed sensor Ⅱ44 and a downward pressure sensor Ⅱ45 are sequentially arranged between the coding device Ⅰ3 and the coding device Ⅱ4. Both the code scanning sensor Ⅰ36, the paper feed sensor Ⅱ44 and the downward pressure sensor Ⅱ45 are arranged on the side of the conveying device A. The code scanning sensor Ⅰ36 is located between the coding machine Ⅰ32 and the code scanner Ⅰ33. When the code scanning sensor Ⅰ36 detects the cigarette box, the code scanner Ⅰ33 scans the No. 1 engineering code of the cigarette box and uploads the scanned code information to the control device 5. When the paper feed sensor Ⅱ44 detects the cigarette box, the paper feed component of the coding machine Ⅱ42 feeds the paper; when the pressing sensor Ⅱ45 detects the cigarette box, the pressure plate of the pneumatic labeling component of the coding machine Ⅱ42 presses down to paste the No. 1 engineering code on the cigarette box. A scanning sensor Ⅱ46 is provided between the coding machine Ⅱ42 and the scanner Ⅱ43. When the scanning sensor Ⅱ46 detects the cigarette box, the scanner Ⅱ43 scans the No. 1 engineering code and uploads the scanning information to the control device 5.

[0042] Specifically, the coding bracket I31 is installed in parallel to the left side of the coding bracket II41, that is, it is installed in series on the conveying device A. Each coding bracket includes vertical bars located on both sides of the conveying device A and a cross bar connected between the two vertical bars, and the cross bar and the vertical bar are made of aluminum alloy. The height of the coding bracket is 2 meters, the width is 1.19 meters, and the thickness of the vertical and cross bars is 8 centimeters. The requirements for coding bracket I31 and coding bracket II41 are as follows: Vibration acceleration ≤17.9m / s 2 , and can carry a weight ≥ 35kg.

[0043] The pusher is a cylinder 11, and the conditions that the cylinder 11 needs to meet are as follows: 1. Action response time ≤ 20ms, cylinder 11 thrust ≥ 45.37N, and cylinder 11 stroke ≥ 300mm. Specifically, the cylinder 11 model selected in this embodiment is ARITACSC40×300.

[0044] Furthermore, the in-position sensor 12 is a photoelectric sensor. Compared with the inductive proximity switch and the small limit travel switch, the photoelectric sensor is convenient to debug and replace (debugging and replacement time < 60s) and has a high limit correct response rate (limit correct response rate ≥ 99.98%).

[0045] Furthermore, the control device 5 of this embodiment uses S7-200. The control device 5 is connected to an alarm, and specifically, the alarm can use an audible and visual alarm 6. The No. 1 engineering code information scanned by the code scanner Ⅰ33 / Ⅱ43 is compared and verified with the corresponding QR code information of the cigarette strips inside the cigarette box to determine whether the brands of the cigarette box and the cigarette strips inside the cigarette box are consistent. If the brands of the two are consistent, the audible and visual alarm 6 displays a green light, and the cigarette box passes smoothly into the next process; if the brands of the two are inconsistent, the audible and visual alarm 6 displays a red light and sounds an alarm, and the control device 5 controls the conveying device A to pause.

[0046] Furthermore, the paper feed sensor, pressure sensor and code scanning sensor are all photoelectric sensors. Compared with the triggering methods of micro switches and visual detection in the prior art, photoelectric sensors have both short triggering response time and low failure rate. Specifically, their triggering response time is ≤10ms, and the equipment failure rate is <3 times / year.

[0047] The specification judgment sensor 21 and the specification verification sensor 22 are photoelectric sensors of the model OPTEX CDD-40N-IR. After the detection lines of the four photoelectric sensors are connected to the control device 5, the detection lines are arranged and fixed using threaded pipes and cable ties.

[0048] The working process of the No. 1 engineering code coding system for the case packer of this embodiment is as follows:

[0049] S1: Smoke box push

[0050] The conveying device A is started, and the cigarette box is input from the conveying device A. When the push sensor detects the cigarette box signal, the cylinder 11 extends outward to push the cigarette box. When the in-place sensor 12 detects the cigarette box signal, the cylinder 11 is retracted.

[0051] S2: Smoke box specification inspection

[0052] When the cigarette box passes through the cigarette box specification detection device 2, the specification detection sensor and the specification verification sensor 22 detect the cigarette box signal and upload it to the control device 5, which determines the specification of the current cigarette box and triggers the corresponding coding device to work.

[0053] When the specification judgment sensor 21 and the specification verification sensor 22 located only on one side of the in-place sensor 12 detect a cigarette box, the specifications of the cigarette box are determined to be a small cigarette box (diamond soft lotus), and the coding device I3 is triggered to work; when the two specification judgment sensors 21 and the two specification verification sensors 22 all detect a cigarette box, the specifications of the cigarette box are determined to be a large cigarette box (diamond soft green), and the coding device II4 is triggered to work.

[0054] S3: Cigarette box coding

[0055] If the current cigarette box is a small cigarette box (diamond soft lotus), when the paper feeding sensor Ⅰ34 detects the cigarette box, the paper feeding component of the coding machine Ⅰ32 feeds paper, and when the pressing sensor Ⅰ35 detects the cigarette box, the pressing plate of the labeling component of the coding machine Ⅰ32 presses down to paste the No. 1 engineering code on the cigarette box;

[0056] If the current cigarette box is a large cigarette box (diamond soft green), when the paper feeding sensor Ⅱ44 detects the cigarette box, the paper feeding component of the coding machine Ⅱ42 feeds paper, and when the pressing sensor Ⅱ45 detects the cigarette box, the pressure plate of the labeling component of the coding machine Ⅱ42 presses down to paste the No. 1 engineering code on the cigarette box.

[0057] S4: Scan the cigarette box

[0058] If the current cigarette box is a small cigarette box (diamond soft lotus), when the code scanning sensor Ⅰ36 detects the cigarette box, the code scanner Ⅰ33 scans the No. 1 engineering code and uploads the scanned code information to the control device 5;

[0059] If the current cigarette box is a small cigarette box (diamond soft lotus), when the code scanning sensor II 46 detects the cigarette box, the code scanner II 43 scans the No. 1 engineering code and uploads the scanned code information to the control device 5 .

[0060] S4: Cigarette box brand proofreading

[0061] The information of the No. 1 engineering code of the cigarette box is compared with the information of the QR code of the cigarette cartons in the cigarette box to determine whether the brands of the cigarette box and the cigarette cartons in the cigarette box are consistent;

[0062] If the brands of the two are consistent, the cigarette box passes smoothly and enters the next process; if the brands of the two are inconsistent, the sound and light alarm 6 sounds an alarm, and the control device 5 controls the conveying device A to pause.

[0063] Example 2

[0064] The content of this embodiment is basically the same as that of Embodiment 1, except that:

[0065] See also Figure 1 The conveying device A is a horizontal conveying device A. The No. 1 engineering code coding system of the case packing machine also includes a vertical conveying device B. The conveying direction of the vertical conveying device B is perpendicular to the conveying direction of the horizontal conveying device A. The output ends of the vertical conveying device B and the output ends of the horizontal conveying device A are provided with a rotating platform C. Cigarette boxes of different specifications are conveyed from the vertical conveying device B to the rotating platform C, rotated 90 degrees, and then conveyed to the horizontal conveying device A.

[0066] Application Examples

[0067] The No. 1 engineering code coding system of the above-mentioned embodiments 1 and 2 was applied to the YP113 type case packer. The specific results are shown in Table 1: (1) The time consumption for case coding was shortened to 0.272 minutes per piece; (2) The defect rate of cigarettes in boxes with irregular logistics code pasting positions was 0%; (3) The system operation stability was > 99.8%; (4) The satisfaction survey of on-site operators was > 99 points.

[0068]

[0069]

[0070]

[0071] After the No. 1 Engineering Code Marking System for the Packing Machine was put into use, there was no need to manually paste the No. 1 Engineering Code, which shortened the time for packaging and labeling, reduced the problem of irregular No. 1 Engineering Code labeling caused by manual packaging, and saved human resources. At the same time, after the system was put into use, the accuracy of No. 1 Engineering Code labeling was guaranteed, which effectively guaranteed the normal production plan of the workshop.

[0072] It should be noted that the control device in this application simply realizes the comparison between the No. 1 engineering code and the cigarette QR code based on the PLC control system. The comparison of barcodes based on the PLC control system is already a fairly mature technology in the prior art, and this application does not involve improvements to its algorithms and procedures.

[0073] It should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
