Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of tobacco production equipment, and particularly relates to a box-strip association and adaptation device and method. Background Art
[0002] With the accelerating digital transformation of the tobacco industry, two-dimensional code technology has become the core means to achieve informatization and refined management of cigarette production. The existing cigarette two-dimensional code "box-condition" association management system binds the unique two-dimensional code identifiers at the levels of cigarette boxes (cartons), strips (carton packs), and cases, and realizes the binding of unique identifiers for products at different levels such as box cigarettes, strip cigarettes, and case cigarettes by constructing a full-chain two-dimensional code association network. The aim is to build a product full-life-cycle traceability system to ensure that the flow of products can be traced throughout the process, strengthen the quality supervision ability, and is an important measure to further standardize the production and operation management of the industry.
[0003] The ZB25B type packaging unit sequentially includes a cigarette pack conveyor belt, a transparent paper forming bin, a double-pack elevator, a cigarette pack output turret, a small box beautifier, a pusher, and a strip box folding channel along the advancing direction of the small box cigarette packs. The small box cigarette packs are conveyed by the cigarette pack conveyor belt into the transparent paper forming bin, and after the small transparent package is formed, they are stacked into upper and lower double packs by the double-pack elevator and pushed into the cigarette pack output turret in sequence. After passing through the rejection station and the cigarette replenishment station, they are sequentially pushed into the small box beautifier. After output, the pusher plate of the pusher pushes the cigarette packs into the strip box in the form of a 5×2 cigarette pack group, and the strip box folding channel folds the strip box and advances in sequence in the form of strip cigarettes. A side seal beautifier is arranged on the left side of the cigarette pack output turret, and a side cigarette replenishment device is arranged on its right side. In the existing "box-condition" association management system, it is necessary to read the codes of the normally advancing small box cigarette packs at the second station in the cigarette pack output turret.
[0004] However, when deploying the ZB25B type packaging unit, since the side seal beautifier occupies the position of the barcode scanner in the existing solution, it is impossible to install a barcode scanner for reading the small box cigarette packs at the second station in the cigarette pack output turret in this model, and the association cannot be achieved. Moreover, the side seal beautifier cannot be removed and its position cannot be changed.
[0005] In addition, in the existing "box-condition" association management system, after the small box two-dimensional code information is read and sorted into the sequence, when the cigarette packs form a 5×2 cigarette pack group, the barcode scanner only reads the first pair (the outermost pair) of cigarette packs in the cigarette pack group. In the ZB25B type packaging unit, the small boxes are input from the cigarette pack output turret to the small box beautifier, and the entrance of the small box beautifier is a liftable cover plate. During daily production, it is easy to have cigarette jams at the small box beautifier part. The operator will lift the cover plate to remove the jammed cigarette packs, and then supplement two intact cigarette packs into the small box beautifier channel. This results in the fact that the manually supplemented cigarette packs are not read by the barcode scanner in sequence, thus causing errors when verifying the 5×2 cigarette pack group.
[0006] Therefore, there is an urgent need to design a new adaptation solution to meet the requirements of scanning and associating small boxes on the production line and improving the accuracy of association. Summary of the Invention
[0007] In view of the deficiencies of the prior art, the present invention develops a box-strip association adaptation device and method. The present invention integrates single-scanner dual-station scanning, anti-reflection light sources, and a multi-level verification and rejection mechanism to achieve accurate reading of the entire process of cigarette packets and dynamic association of boxes and strips, breaking through the equipment space limitations and ensuring the integrity of quality traceability.
[0008] The technical solution for the present invention to solve the technical problems is as follows: The present application provides a box-strip association adaptation device, including a cigarette packet output turret, a pusher, and a strip box folding channel arranged in sequence along the advancing direction of the cigarette packets. A side supplementary packet device is arranged outside the cigarette packet output turret; The side supplementary packet device includes a side supplementary packet library and a push plate assembly. A push plate channel is opened at the bottom end of the side supplementary packet library. The push plate assembly includes a push plate, and a reading window adapted to the cigarette packet two-dimensional code is opened on the push plate; The working station in the cigarette packet output turret corresponding to the push plate channel is the shooting station; an auxiliary light source is arranged horizontally on the left side of the shooting station; A code reading and scanning device is arranged outside the push plate channel. The reading lens of the code reading and scanning device is aligned with the two-dimensional code mark at the reading window; the two-dimensional codes of the normally advancing cigarette packets in the shooting station and the supplementary cigarette packets that fall from the side supplementary packet library and are pushed into the shooting station through the push plate are read by the code reading and scanning device and queued; A verification scanning device is arranged outside the in-place working station of the pusher for reading the cigarette packet group sequence, and the cigarette packet group is pushed into the strip box by the pusher to form a carton of cigarettes; A strip box scanning device is arranged on the advancing path of the strip box folding channel. The strip box scanning device is used for reading the strip box two-dimensional code and associating it with the corresponding cigarette packet group series.
[0009] As an improvement of the above solution, the push plate assembly further includes a cylinder that drives the push plate to move towards the side supplementary packet library.
[0010] As an improvement of the above solution, two reading windows are opened. The two reading windows are opened at the side edge position of the push plate in a vertically symmetric form, and the opening position of the reading window corresponds to the position where the two-dimensional code mark on the surface of the cigarette packet is located; A part of the structure of the push plate between the two reading windows is a guide rod, and the guide rod is attached to the connection between the upper and lower two cigarette packets.
[0011] As an improvement to the above solution, the angle between the barcode scanner and the plane of the cigarette pack QR code is 70°, the angle between the auxiliary light source and the plane of the cigarette pack QR code is 45°, and the distance between the auxiliary light source and the cigarette pack QR code is 30 mm.
[0012] As an improvement to the above solution, the auxiliary light source includes a light source bracket, lamp beads and a lamp cover. The light source bracket is installed on the packaging machine, the lamp beads are installed on the light source bracket, and the lamp cover covers the lamp beads.
[0013] As an improvement to the above solution, the light source bracket includes an adjusting plate and a mounting plate connected to each other. The adjusting plate is provided with strip-shaped adjusting holes. The light source bracket is connected to the packaging machine through the adjusting holes, and the distance and angle of the lamp beads are adjusted by cooperating with the adjusting holes through bolts. The lamp beads are installed inside the mounting plate, and the lamp cover is clamped on the mounting plate and covers the outside of the lamp beads.
[0014] As an improvement to the above solution, the carton-strip association and adaptation device further includes a cigarette pack conveyor belt, a transparent paper forming bin and a double-pack elevator along the traveling direction of the small box cigarette packs. The output end of the double-pack elevator is connected to the input end of the cigarette pack output turret; A quality inspection barcode scanner is arranged on one side of the cigarette pack conveyor belt for reading the cigarette pack QR code on the cigarette pack conveyor belt.
[0015] As an improvement to the above solution, the output end of the cigarette pack output turret is connected to the pusher through a small box beautifier; a carton rejection mechanism is arranged on the traveling path of the carton folding channel; A cigarette squeezing detection device is arranged inside the small box beautifier, and the cigarette squeezing detection device is communicatively connected to an alarm device.
[0016] The present invention also provides a carton-strip association and adaptation method, which is applied to the carton-strip association and adaptation device described in any one of the above. The method includes: Step S1: Determine whether the cigarette pack QR code is readable Read the cigarette pack QR code on the cigarette pack conveyor belt to determine whether it is readable. The cigarette packs are lifted into double-box cigarette packs stacked vertically and enter the cigarette pack output turret in a recursive form; Step S2: Read the cigarette pack QR code and queue it For the cigarette packs successfully recognized in step S1, read the cigarette pack QR code at the shooting station of the cigarette pack output turret and queue it; For the cigarette packs unsuccessfully recognized in step S1, they are rejected inside the cigarette pack output turret, and then cigarette packs are replenished to the shooting station of the cigarette pack output turret, and the replenished cigarette pack QR code is read and queued; Step S3: Verify the cigarette pack group sequence The cigarette packets are output from the cigarette packet output turret and enter the small box beautifier in a recursive manner until they reach the in-place station. The two-dimensional code of the first pair of cigarette packets in the 5×2 cigarette packet group is read to verify whether the sequence of the cigarette packet group after grouping is consistent with the current reading sequence. Step S4: Read the two-dimensional code of the carton and associate it The pusher pushes the cigarette packets into the carton in the form of a 5×2 cigarette packet group to form a carton of cigarettes. The two-dimensional code on the surface of the moving carton is read and associated with the corresponding cigarette packet group sequence in step S3. Step S5: Determine whether the carton of cigarettes needs to be rejected If the reading is successful in all of steps S2 - S4, the carton of cigarettes formed by this cigarette packet group completes the "box - carton" association. If the reading is unsuccessful in any one of steps S2 - S4, the carton of cigarettes formed by the cigarette packet or carton with unsuccessful reading is rejected. If squeezing or defective products are detected in the small box beautifier, the cover of the small box beautifier is opened to replace the cigarette packets, and the corresponding carton of cigarettes is rejected to prevent the unread replacement cigarette packets from entering the next process.
[0017] As an improvement to the above solution, in step S5, if squeezing or defective products are detected in the small box beautifier, the squeezing detection device sends a high - level alarm signal to the PLC controller and triggers an audible and visual alarm. The cover of the small box beautifier is opened to replace the cigarette packets. The PLC controller receives the input signal for opening the cover of the small box beautifier, generates a rejection instruction and starts the shift chain to position the replacement cigarette packets. The shift chain analyzes the moving station of the carton of cigarettes through the rotation phase signal of the encoder. When the corresponding carton of cigarettes moves to the carton rejection station, the PLC controller outputs an electric control signal to drive the carton rejection mechanism to act and reject the corresponding carton of cigarettes, preventing the unread replacement cigarette packets from entering the next process.
[0018] Compared with the prior art, the above solution has the following advantages or beneficial effects: 1. The present invention realizes the reading of the two - dimensional code of the cigarette packets moving normally in the cigarette packet output turret through a single barcode scanner, and also realizes the reading of the two - dimensional code of the cigarette packets at the replenishment station where they fall in the side replenishment pack library, achieving the full reading of the small box cigarette packets, simplifying the structure and operation process, and also solving the problem that it is not convenient to read the two - dimensional code of the cigarette packets in the cigarette packet output turret due to the existence of the side - seal beautifier on the left side of the cigarette packet output turret. 2. The design of the auxiliary light source in the present invention can eliminate the reflection caused by the direct light source of the barcode scanner due to the transparent paper of the small box, and also sufficiently reduce the influence of insufficient light on barcode scanning, ensuring clear imaging of the barcode scanner and improving the reading accuracy.
[0019] 3. In the present invention, the design of removing the whole carton of cigarettes corresponding to the cigarette pack replaced at the small box beautifier avoids the associated errors caused by the unread replacement cigarette pack, prevents it from entering the next process, and improves the association accuracy between the "box and carton".
[0020] 4. In the present invention, the product inspection code scanner is used to determine whether the two-dimensional code on the small box on the cigarette pack conveyor belt is readable; the code reading scanner reads the two-dimensional codes of the small box cigarette packs and the replenished cigarette packs in the cigarette pack output turret in motion and arranges them in a queue; the verification scanner reads the two-dimensional code on the surface of the first pair of cigarette packs in the 5×2 cigarette pack group at the in-place station to verify the cigarette pack group sequence; the carton code scanner reads the two-dimensional code on the surface of the carton to associate the cigarette pack group sequence; the association between the "box and carton" is realized through the two-dimensional code recognition of multiple parts, ensuring that the whole process of product flow is traceable and strengthening the quality supervision of the product.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] Embodiment 1 Refer to Figure 1 and 2 , this embodiment provides a box-strip association and adaptation device, including a vertical side-packing device 2, a cigarette pack output turret 1, a code reading and scanning device 3, and an auxiliary light source 4. Under the action of the auxiliary light source 4, the code reading and scanning device 3 scans the two-dimensional code of the normally moving cigarette packs in the cigarette pack output turret 1 and the two-dimensional code of the cigarette packs replenished by the side-packing device 2.
[0031] The above-mentioned side-packing device 2 includes a side-packing library 21 and a push plate assembly. The bottom end of the side-packing library 21 is provided with a push plate channel. The push plate assembly includes a push plate 22 and a cylinder 23 that drives the push plate 22 to move towards the side-packing library 21. A reading window 221 is provided on the push plate 22. The side-packing library 21 clamps the vertically stacked and stacked cigarette packs, so that the cigarette packs finally fall into the push plate channel by their own gravity, and then the push plate assembly pushes the falling cigarette packs from the push plate channel into the mold box of the cigarette pack output turret 1 to complete the cigarette replenishment action.
[0032] The above-mentioned code reading and bar code scanning device 3 is arranged on the outer side of the pusher channel (the side where the cylinder 23 is located), and the reading lens of the code reading and bar code scanning device 3 is aligned with the two-dimensional code identification at the reading window 221. The working position in the cigarette packet output turret 1 opposite to the pusher channel is the shooting position for cigarette packet two-dimensional code identification. When no cigarette replenishment is required, there is no cigarette packet in the pusher channel, and the code reading and bar code scanning device 3 reads the two-dimensional code of the normally moving cigarette packet at the shooting position in the mold box of the cigarette packet output turret 1 through the reading window 221. When cigarette replenishment is required, two cigarette packets fall from the side cigarette replenishment library 21, and the replenished cigarettes are pushed into the shooting position through the pusher assembly. The code reading and bar code scanning device 3 can also read the two-dimensional codes of the two replenished cigarette packets through the reading window 221. This design realizes the reading of the two-dimensional code of the normally moving cigarette packet in the cigarette packet output turret 1 by one code reading and bar code scanning device 3, and also realizes the reading of the two-dimensional code of the cigarette packet at the replenishing position falling in the side cigarette replenishment library 21, realizing the full reading of the small box cigarette packets, simplifying the structure and operation process, and also solving the problem that it is not convenient to read the two-dimensional code of the cigarette packet in the cigarette packet output turret 1 due to the existence of the side sealing beautifier 5 on the left side of the cigarette packet output turret 1.
[0033] Refer to Figure 6 , the above-mentioned auxiliary light source 4 is located on the horizontal left side of the shooting position of the cigarette packet output turret 1. Specifically, the included angle between the bar code scanning device and the two-dimensional code plane of the cigarette packet is 70°, the included angle between the auxiliary light source 4 and the two-dimensional code plane of the cigarette packet is 45°, and the distance between the auxiliary light source 4 and the two-dimensional code of the cigarette packet is 30 mm. In the prior art, since the scanning light of the code reading and bar code scanning device 3 needs to read the two-dimensional code of the cigarette packet through the pusher channel, the space is narrow and the external light is insufficient; in addition, the adjustable range is limited when installing the code reading and bar code scanning device 3, and the requirement of the included angle between the code reading and bar code scanning device 3 and the cigarette packet of 15 - 30 degrees cannot be achieved. Therefore, when the direct light source of the code reading and bar code scanning device 3 shines on the small box transparent paper on the surface of the cigarette packet, since the small box cellophane has not been ironed by a soldering iron and the shrink film is not completely flat, there is a certain probability that the direct light source causes reflection and affects code reading, resulting in a decrease in the code reading rate. Therefore, the design of the auxiliary light source 4 can eliminate the reflection caused by the direct light source of the code reading and bar code scanning device 3, and fully reduce the influence of insufficient light on code scanning, ensuring clear imaging and accurate reading of the code reading and bar code scanning device 3.
[0034] In this embodiment, refer to Figure 3, there are two reading windows 221 provided above. The two reading windows 221 are provided at the side edge position of the push plate 22 in a vertically symmetrical form. The opening position of the reading window 221 can correspond to the position of the two-dimensional code identification on the surface of the cigarette pack, so that the cigarette pack two-dimensional code is exposed, so that the code reading and scanning device 3 can read the two-dimensional code identification on the surface of the cigarette pack through the reading window 221. A part of the structure of the push plate 22 between the two reading windows 221 is the guide rod 222. The guide rod 222 is attached to the connection of the upper and lower cigarette packs, providing a guiding function for the cigarette pack to ensure that the cigarette pack can be smoothly pushed out of the push plate channel by the push plate 22, and preventing the situation that the cigarette pack is skewed due to uneven force when the cigarette pack is pushed forward by the push plate 22 and then gets stuck at the bottom of the side cigarette pack replenishment library 21.
[0035] In this embodiment, the above auxiliary light source 4 includes a light source bracket 41, lamp beads and a lamp cover. The light source bracket 41 is installed on the packaging unit, the lamp beads are installed on the light source bracket 41, and the lamp cover covers the lamp beads. The lamp beads are Samsung LM281B+ PRO, which is a medium-power LED with characteristics such as high brightness, high luminous efficiency, and high color rendering index; the light source bracket 41 is made of aluminum alloy, with characteristics such as light weight, high strength, corrosion resistance and heat resistance, avoiding frequent replacement and maintenance, and enhancing stability.
[0036] Further, refer to Figure 4 and 5 , the above light source bracket 41 includes an adjusting plate 411 and a mounting plate 412 that are vertically connected; a strip-shaped adjusting hole 4111 is opened on the adjusting plate 411, and the light source bracket 41 is connected to the packaging unit through the adjusting hole 4111. The lamp beads are installed in the mounting plate 412, and the lamp cover is clamped on the mounting plate 412 and covers the outside of the lamp beads. Specifically, the light source bracket 41 is connected to the packaging unit by passing bolts through the adjusting hole 4111. The light source bracket 41 can adjust the distance between the lamp beads and the cigarette pack two-dimensional code through the adjusting hole 4111, and can also rotate the light source bracket 41 around the bolt to adjust the angle of the lamp beads.
[0037] Embodiment 2 The content of this embodiment is basically the same as that of the above Embodiment 1, the difference is: Refer to Figure 1 , the above carton strip association and adaptation device further includes a cigarette pack conveyor belt 6 along the traveling direction of the small box cigarette pack, a transparent paper forming bin and a double-pack elevator 7. The output end of the double-pack elevator 7 is connected to the input end of the cigarette pack output turret 1. A product inspection and code scanner 8 is provided on one side of the cigarette pack conveyor belt 6 for reading the codes of the cigarette packs on the cigarette pack conveyor belt 6. The small box cigarette packs are conveyed by the cigarette pack conveyor belt 6 into the transparent paper forming bin. After the small transparent packages are formed, the double-pack elevator 7 stacks and lifts the small box cigarette packs into doubles, and then pushes them into the cigarette pack output turret 1 through the pushing device.
[0038] The output end of the cigarette pack output turret 1 is sequentially connected in transmission with a small box beautifier 9, a pusher 10, and a strip box folding channel 11. The pusher 10 includes a pushing plate and a in-place station connected to the output end of the small box beautifier 9. A verification code scanner 12 is arranged outside the in-place station. A strip box code scanner 13 and a strip cigarette rejection mechanism 14 are sequentially arranged on the traveling path of the strip box folding channel 11. The strip box code scanner 13 is used to read the two-dimensional code on the surface of the strip box, and the strip cigarette rejection mechanism 14 is used to reject unqualified strip cigarettes. The cigarette packs enter the small box beautifier 9 in a push-and-pull form and then are transported to the in-place station. The verification code scanner 12 reads the two-dimensional code on the surface of the first pair of cigarette packs in the 5×2 cigarette pack group. The pushing plate pushes the cigarette packs into the strip box in the form of a 5×2 cigarette pack group. The strip box folding channel 11 folds the strip box and then advances in a push-and-pull form in the form of a strip cigarette. The strip box code scanner 13 reads the two-dimensional code on the surface of the strip box.
[0039] A cigarette jamming detection device is arranged in the small box beautifier 9. The cigarette jamming detection device is communicatively connected with an alarm device. Whether there is cigarette jamming in the small box beautifier 9 is detected through the cigarette jamming detection device. If cigarette jamming is detected, the alarm device issues an alarm to remind the staff to replace the cigarette packs.
[0040] Embodiment 3 This embodiment provides a box-strip association adaptation method, which is applied to the box-strip association adaptation device in any one of the above-mentioned Embodiment 2. The method includes: Step S1: Determine whether the cigarette pack two-dimensional code is readable The product inspection code scanner 8 scans the two-dimensional code on the cigarette packs on the cigarette pack conveyor belt 6 to determine whether it is readable. After the cigarette packs are wrapped with small transparent paper and the drawstring, they are lifted by the double-pack elevator 7 into vertically stacked double-box cigarette packs, and are pushed into the cigarette pack output turret 1 through the pushing device; Step S2: Read the cigarette pack two-dimensional code and queue it For the cigarette packs successfully recognized by the product inspection code scanner 8, the two-dimensional code on the cigarette packs is read by the code reading and scanning device 3 at the shooting station of the cigarette pack output turret 1 and queued; For the cigarette packs unsuccessfully recognized by the product inspection code scanner 8, they are rejected at the cigarette pack rejection station of the cigarette pack output turret 1, and then two boxes of cigarette packs are replenished into the shooting station of the cigarette pack output turret 1 through the side replenishment device 2, and the two-dimensional code on the replenished cigarette packs is read by the code reading and scanning device 3 and queued; Step S3: Verify the cigarette pack group sequence The cigarette packs are output from the cigarette pack output turret 1 and enter the small box beautifier 9 in a push-and-pull form until the in-place station. The verification code scanner 12 reads the two-dimensional codes of the first pair of cigarette packs in the 5×2 cigarette pack group to verify and confirm whether the cigarette pack group sequence after grouping is consistent with the recognition sequence of the recognition code scanner; Step S4: Read the strip box two-dimensional code The pusher 10 pushes the cigarette packs into the carton in the form of a 5×2 cigarette pack group to form a carton of cigarettes. The carton travels along the carton folding channel 11, and at the same time, the two-dimensional code on the surface of the carton is read by the carton scanner 13 and associated with the cigarette pack group sequence verified in step S3. Step S5: Determine whether it is necessary to reject the carton of cigarettes If the code reader 3, the verification scanner 12, or the carton scanner 13 all succeed in reading, the carton of cigarettes formed by this cigarette pack group completes the "carton-carton" association. If any one of the code reader 3, the verification scanner 12, or the carton scanner 13 fails to read, the carton of cigarettes formed by the cigarette pack or carton with the failed reading is rejected by the carton rejection mechanism 14. If squeezing or defective products are detected in the small box beautifier 9, the cover of the small box beautifier 9 is opened to replace the cigarette pack, and the corresponding carton of cigarettes is rejected by the carton rejection mechanism 14 to prevent the unread replacement cigarette pack from entering the next process.
[0041] Among them, In step S2 of this embodiment, as long as one of the two cigarette packs fails to be read, both of these two cigarette packs are rejected at the same time.
[0042] In step S2 of this embodiment, after the replenished cigarette pack is completely pushed into the designated code scanning area, that is, after entering the shooting station, the cigarette pack reaches the designated phase interval of the cigarette pack output turret 1 to trigger the code reader 3 to perform the code scanning action. This post-push phase-triggered code scanning method can be consistent with the phase triggered during the normal travel of the cigarette packs in the cigarette pack output turret 1, which not only simplifies the operation process but also improves the stability of the two-dimensional code reading of the cigarette pack compared with the photoelectric trigger method.
[0043] In step S5 of this embodiment, as long as there is one cigarette pack in the cigarette pack group in the carton that fails to be read or there is an unread replacement cigarette pack, the entire carton of cigarettes is rejected.
[0044] In step S5 of this embodiment, since the verification scanner 12 can only scan a pair of cigarette packs on the outermost side of the cigarette pack group, when an error is found, the corresponding carton of cigarettes can be rejected as a whole, but it cannot verify the other four pairs of cigarette packs in the cigarette pack group. If the other four pairs of cigarette packs enter the sequence without being read due to manual replacement and cannot be verified, an association error will occur. Therefore, the design of rejecting the entire carton of cigarettes corresponding to the cigarette pack replaced at the small box beautifier 9 improves the "carton-carton" association accuracy.
[0045] Embodiment 4 The content of this embodiment is basically the same as that of the above-mentioned Embodiment 3, except that: In step S5, if squeezing out cigarettes or defective products are detected in the small box beautifier 9, the cigarette squeezing detection device sends a high-level alarm signal to the PLC controller (model Siemens S7-1200) and triggers an audible and visual alarm. When the cover of the small box beautifier 9 is opened to replace the cigarette pack, the PLC controller receives the input signal for opening the cover of the small box beautifier 9, generates a rejection instruction and starts the shift chain to position and replace the cigarette pack. The shift chain analyzes the moving station of the carton of cigarettes through the rotation phase signal of the encoder. When the corresponding carton of cigarettes moves to the carton rejection station, the PLC controller outputs an electric control signal to drive the carton rejection mechanism 14 to act, rejecting the corresponding carton of cigarettes to prevent the unread replaced cigarette pack from entering the next process.
