Description

Technical Field

[0001] The present invention belongs to the technical field of photoelectric detection, and in particular relates to a lining detection device and a detection method based on photoelectric detection. Background Art

[0002] See also Figure 1 In the production process of cigarette packs, unqualified cigarette packs need to be removed. From the principle of existing equipment, there is an inner lining paper detection designed at the junction of the second and third wheels, which mainly detects whether the cigarette pack pull tab is missing, whether the inner lining paper is warped, etc. through a photoelectric detector. Figure 2 The pull tab position is shown in Figure 2. The above two types of poor quality cigarette packs will be rejected before entering the third wheel.

[0003] However, the inventors have found that there are mainly two situations in which the discarded waste cigarette packs are discarded. Figure 3 , because the pull tab is not pressed tightly, causing the pull tab to warp. This defect can be solved by simply pressing the pull tab again; second, see Figure 4 , the crease of the opening of the cigarette pack lining was not folded properly at the beginning, resulting in serious warping of the opening. In this case, it can only be scrapped. In the two cases, the former is more common, and it is a waste to scrap it.

[0022] As an optional embodiment of the photoelectric detection device 300, see Figure 7 and Fig. 9In one embodiment of the present application, the photoelectric detection device 300 includes: an outer guide plate 311 and an inner guide plate 312 located on both sides of the cigarette pack conveying device 1; an outer detection component 32, installed on the outer guide plate 311, for detecting defects on the outer end surface of the cigarette pack; an inner detection component 33, installed on the inner guide plate 312, for detecting defects on the inner end surface of the cigarette pack.

[0023] In this embodiment, an external detection component 32 is provided on the outer guide plate 311, which can be used to detect the lifting of the pull tab on the outer end surface of the cigarette pack (i.e., the end surface where the pull tab is located) and the defect of the cigarette pack opening (such as Figure 3 and Figure 4 ), and whether there is a defect that the lining paper exceeds the upper and lower edges of the end surface; by setting an internal detection component 33 on the inner guide plate 312, it can be used to detect whether there is a defect that the lining paper on the inner end surface of the cigarette package exceeds the upper and lower edges of the end surface, thereby improving the comprehensiveness of cigarette package detection.

[0024] For details, see Fig.10 The external detection component 32 includes: two first photoelectric tubes 321 at an angle of 30-60 degrees, whose detection range covers the outer end surface of the cigarette package; an optical fiber sensor 322 for detecting the lifting of the pull tab and the defect of the cigarette package opening (such as Figure 3 and Figure 4 ); wherein the first photoelectric tube 321 and the optical fiber sensor 322 are both connected to the control module, and the optical fiber sensor 322 is also used to trigger the first photoelectric tube 321 to detect.

[0025] In this embodiment, the two first photoelectric tubes 321 are installed at a certain angle, and their detection surface covers the end surface of the pull-tab of the cigarette pack, thereby expanding the detection range and making the detection surface wider; the optical fiber sensor 322 can be installed in the defective areas for the pull-tab tilting and cigarette pack opening (such as Figure 3 and Figure 4 ) can be used as a trigger for detection and as a detection measure, adding an extra layer of detection protection for areas prone to defective products.

[0026] Preferably, the two first photoelectric tubes 321 may be at an angle of 45 degrees.

[0027] See also Fig.11 Furthermore, the inner detection component 33 includes two second photoelectric tubes 331 with an angle of 30-60 degrees, and its detection range covers the inner end surface of the cigarette package.

[0028] In this embodiment, the internal detection component 33 is a newly added detection component on the original equipment, which includes two second photoelectric tubes 331 with an angle of 30-60 degrees. The layout of the detection surface covers the inner end surface of the cigarette package, thereby expanding the detection range and ensuring product quality. Together with the external detection component 32, it forms an overall detection and can comprehensively detect defects in cigarette package packaging paper.

[0029] Preferably, the two second photoelectric tubes 331 form an angle of 45 degrees.

[0030] See also Fig. 9 and Fig.10 Optionally, the external detection component 32 also includes a first shell 323, and the first photoelectric tube 321 and the optical fiber sensor 322 are arranged in the first shell 323; the outer guide plate 311 is provided with a first mounting hole 3111 for accommodating the first shell 323.

[0031] Optionally, the inner detection component 33 further includes a second shell 332 , and the second photoelectric tube 331 is disposed in the second shell 332 ; the inner guide plate 312 is provided with a second mounting hole 3121 for accommodating the second shell 332 .

[0032] In this embodiment, the detection components of the external detection component 32 are accommodated in the first shell 323, have a high degree of integration, and can be modularly installed on the outer guide plate 311; similarly, the internal detection component 33 can be modularly installed on the inner guide plate 312.

[0033] In this embodiment, see Fig.10 , Fig.12 , Fig.13 and Fig.14 The optical fiber sensor 322 is installed in an adjustment installation sleeve 324 with a centering structure, which can facilitate the adjustment of the detection position of the optical fiber sensor 322.

[0034] Specifically, an adjusting sleeve mounting hole 3231 is provided in the first shell 323, through which the adjusting sleeve 324 can be inserted; a fastening hole 3232 connected with the adjusting sleeve mounting hole 3231 is provided on the side wall of the first shell 323, for allowing the fastener 3233 to pass through to tighten the adjusting sleeve 324; an optical fiber sensor accommodating hole 3241 is eccentrically provided in the adjusting sleeve 324, and a rotation groove 3242 is provided at the tail end of the adjusting sleeve 324.

[0035] In this embodiment, the optical fiber sensor 322 can be fixed to the optical fiber sensor accommodating hole 3241; when adjusting, the adjusting mounting sleeve 324 can be rotated by inserting a tool into the groove 3242. Since the optical fiber sensor 322 is eccentrically installed, its detection height can change accordingly; after rotating to the preset detection height, the adjusting mounting sleeve 324 can be tightened by the fastener 3233 to fix the position of the adjusting mounting sleeve 324.

[0036] For further information, see Fig. 9 The outer guide plate 311 and the inner guide plate 312 are both provided with a channel hole 313 at the second detection position 200 .

[0037] As an alternative embodiment of the repair mechanism 410, see Figure 7 and Figure 8 The repair mechanism 410 includes: a linear driver 411, which is installed on the outside of the outer guide plate 311, and its driving end is facing the channel hole 313 of the outer guide plate 311; a fixed plate 412, which is arranged at the driving end of the linear driver 411; a clamping plate 413, which is connected to the fixed plate 412 through a plurality of spring telescopic rods 414; and a lifting driver 415, which is arranged at the lower part of the inner guide plate 312, and its driving end is connected to a baffle 416 for blocking the inner side of the channel hole 313 on the inner guide plate 312; the linear driver 411 is used to drive the fixed plate 412 to move forward, so as to press the cigarette pack onto the baffle 416 through the clamping plate 413.

[0038] In this embodiment, during repair, the lifting drive 415 drives the baffle 416 to rise, blocking the inner side of the channel hole 313 on the inner guide plate 312; the driving end of the linear drive 411 extends out, and the fixed plate 412 drives the clamping plate 413 to squeeze the end face of the cigarette pack through the spring telescopic rod 414.

[0039] Furthermore, the repair result detection module 420 includes: a pressure sensor 421 and a displacement sensor 422 electrically connected to the processing module; the pressure sensor 421 is arranged between the fixed plate 412 and the end of the spring telescopic rod 414, and is used to obtain the pressure applied to the cigarette pack by the clamping plate 413; and the displacement sensor 422 is arranged on the linear driver 411, and is used to obtain the extended distance of the fixed plate 412; wherein when the fixed plate 412 is extended by a preset distance, the pressure sensor 421 obtains the first pressure value applied to the cigarette pack by the clamping plate 413; if the first pressure value is greater than the first preset value, the processing module determines that the repair has failed, otherwise the repair is successful.

[0040] Furthermore, the scrap ejection module 430 includes: an electromagnet module 431 arranged on the fixed plate 412 and electrically connected to the processing module; when the pressure value obtained by the pressure sensor 421 that the clamping plate 413 applies to the cigarette pack is greater than a second preset value, the processing module controls the electromagnet module 431 to suck the clamping plate 413; and when the cigarette pack repair fails, the processing module controls the lifting driver 415 to drive the baffle 416 to descend, and controls the electromagnet module 431 to release the clamping plate 413, so as to bounce the cigarette pack onto the scrap conveying device 500 through the spring telescopic rod 414; wherein the scrap conveying device 500 is arranged in the channel hole 313 of the inner guide plate 312.

[0041] In this embodiment, the scrap conveying device 500 may be a conveyor belt conveyor.

[0042] The following is an example of the complete detection process: Step S1, perform a preliminary defect detection on the cigarette pack and then send it to the second detection position.

[0043] In step S1, specifically, at the first detection position 100, the photoelectric detection device 300 detects whether the lining paper on the two end surfaces of the cigarette pack exceeds the upper edge and the lower edge, and whether there is a defect of the pull tab being lifted.

[0044] Step S2, judging the preliminary bad detection result; if the detection is qualified, the cigarette package waits to be grasped and enters the next process; otherwise, proceed to step S3.

[0045] Specifically, if the photoelectric detection device 300 detects no defect, the cigarette pack is qualified and waits to be captured to the next step at the second detection position. If the photoelectric detection device 300 detects a defect, it is further determined whether it is a repairable defect.

[0046] Step S3, determine whether it is a repairable cigarette pack; if so, proceed to step S4, otherwise proceed to step S6.

[0047] For example, if only the optical fiber sensor 322 for detecting the pull tab detects that the pull tab is tilted or the cigarette pack opening is defective (such as Figure 3 and Figure 4 ) and other sensors detect that the cigarette pack is normal, then the cigarette pack is a repairable cigarette pack and can be repaired in step S4; conversely, as long as any sensor except the optical fiber sensor 322 detects a defect, the cigarette pack is an unrepairable cigarette pack and directly enters step S6 to send the cigarette pack to the scrap conveying device 500.

[0048] Step S4, repairing the end surface of the cigarette pack.

[0049] Specifically, after the processing module determines that the cigarette pack located at the second detection position is a repairable cigarette pack, the processing module controls the lifting driver 415 to drive the baffle 416 to rise, blocking the inner side of the channel hole 313 on the inner guide plate 312; the processing module controls the driving end of the linear driver 411 to extend, and the fixed plate 412 drives the clamping plate 413 to squeeze the end face of the cigarette pack through the spring telescopic rod 414.

[0050] Step S5, judging the repair result; if the repair is successful, the cigarette pack waits to be grabbed and enters the next process; otherwise, it proceeds to step S6.

[0051] Specifically, when the fixing plate 412 gradually moves forward until the pressing plate 413 presses the end face of the cigarette pack, the displacement sensor 422 can obtain the distance of the extension of the fixing plate 412 in real time. When the fixing plate 412 moves to a preset distance (the position corresponding to the preset distance can be: assuming that the cigarette pack is a qualified cigarette pack, the front end face of the pressing plate 413 is located 2-3mm from the end face of the cigarette pack), the pressure sensor 421 can obtain the first pressure value applied by the pressing plate 413 to the cigarette pack. Figure 3 As shown in the defect, the lifted pull tab has not been pressed to the end surface of the cigarette pack by the pressing plate 413, so the first pressure value is very small; Figure 4 The defective, warped opening lining paper will be compressed and folded, and the first pressure value will be larger. Therefore, a first preset value can be set, and the first pressure value can be compared with it. If the first pressure value is greater than the first preset value, the processing module determines that the repair has failed (belongs to Figure 4 If the pull tab and inner paper are made of metal foil, the default is Figure 3 The defect can be repaired by simply squeezing the end face of the cigarette pack with the pressing plate 413).

[0052] It should be noted that, because the pressing plate 413 is to press the end surface of the cigarette pack, the final distance of the fixed plate 412 extending is greater than the preset distance; that is, when the pressing plate 413 presses the end surface of the cigarette pack, whether Figure 3 still Figure 4 If the spring expansion rod 414 is defective, it will be squeezed.

[0053] Furthermore, in this step, in order to prevent the cigarette pack from being crushed, when the pressure value applied to the cigarette pack by the pressing plate 413 obtained by the pressure sensor 421 in real time is greater than a second preset value, the processing module controls the electromagnet module 431 to suck the pressing plate 413.

[0054] For example, facing Figure 3 In order to effectively press the pull-tab onto the end face of the cigarette pack, the fixing plate 412 continues to extend forward after extending to the preset distance; until the pressure value obtained by the pressure sensor 421 in real time that the pressure value applied to the cigarette pack by the pressing plate 413 is greater than the second preset value, indicating that the pull-tab has been pressed, the processing module controls the electromagnet module 431 to suck the pressing plate 413, that is, the pressing plate 413 is sucked back a certain distance through the electromagnet module 431.

[0055] face Figure 4When the fixing plate 412 is extended, the pressing plate 413 gradually squeezes the warped inner lining paper, and the pressure value obtained by the pressure sensor 421 in real time from the pressing plate 413 applied to the cigarette pack will increase rapidly. When the pressure value is greater than the second preset value, the processing module controls the electromagnet module 431 to suck the pressing plate 413, that is, the electromagnet module 431 sucks the pressing plate 413 back to a certain distance to prevent the cigarettes in the cigarette pack from being crushed.

[0056] Step S6, sending the cigarette packs to the waste conveying device.

[0057] In step S6, there are two situations: situation 1: the irreparable cigarette packs determined in step S3 are directly sent to the scrap conveying device without being repaired; situation 2: the irreparable cigarette packs determined in step S5 are sent to the scrap conveying device.

[0058] Implementation process of situation one: the baffle 416 does not block the channel hole 313 on the inner guide plate 312; the processing module controls the driving end of the linear drive 411 to extend, and the clamping plate 413 pushes the cigarette pack directly to the scrap conveying device 500 located in the channel hole 313 on the inner guide plate 312.

[0059] Implementation process of scenario two: the initial state is the state of completed repair, that is, the clamping plate 413 is sucked by the electromagnet module 431, and the baffle 416 is blocked on the inner side of the channel hole 313 on the inner guide plate 312; on this basis, the processing module controls the lifting driver 415 to drive the baffle 416 to descend, and controls the electromagnet module 431 to release the clamping plate 413, so as to reset the clamping plate 413 through the spring telescopic rod 414 to bounce the cigarette pack onto the scrap conveying device 500.
