Description

Technical Field

[0001] This utility model relates to the field of tobacco production equipment technology, and in particular to a QR code recognition device for cigarette packs. Background Technology

[0002] With the accelerated digital transformation of the tobacco industry, QR code technology has become a core means to achieve informatization and refined management of cigarette production. The existing cigarette QR code "box condition" association management system binds unique QR code identifiers at the cigarette box, carton, and package levels. By constructing a full-chain QR code association network, it achieves unique identifier binding for different levels of products such as boxes, cartons, and packages. This aims to build a product lifecycle traceability system, ensuring full traceability of product flow, strengthening quality supervision capabilities, and is an important measure to further standardize the industry's production and operation management.

[0003] The Zhangyan cigarette packaging workshop designed multiple barcode scanner adaptation solutions for the ZB45 packaging machine to achieve information association. That is, by scanning the QR codes on the surface of small boxes, cartons, and cartons and uploading the data to the central system in real time, information at each level can be associated.

[0004] The barcode scanners in the ZB45 packaging unit include a barcode reader and a cigarette pack replenishment barcode scanner. The barcode reader faces the second station of the cigarette pack output turret and is used to read the QR codes on the surface of the small boxes during the process and queue them up. The cigarette pack replenishment barcode scanner faces the bottom two cigarette packs in the replenishment warehouse and is used to read the QR codes of the two cigarette packs that are about to be replenished and queue them up.

[0005] However, when deploying the ZB25B packaging unit, the side-sealed packaging containers for the small boxes occupied the space originally designated for the barcode scanner, making it impossible to install the scanner and establish a data association. Furthermore, the side-sealed packaging containers could not be removed or repositioned. Therefore, the barcode scanner layout scheme used in the ZB45 packaging machine could not be used in the ZB25B packaging unit, necessitating the design of a new QR code recognition device for cigarette packs to meet the need for scanning small boxes on the production line. Utility Model Content

[0006] This invention addresses the shortcomings of existing technologies by developing a QR code recognition device for cigarette packs. This invention uses a single scanner to read the QR codes of cigarette packs traveling on the output turret and those falling from the side replenishment warehouse, simplifying the structure and overcoming the space limitations of the side-sealed packaging container. An auxiliary light source is used to eliminate reflections from the transparent paper and insufficient supplementary lighting, effectively improving image clarity and reading accuracy.

[0007] The technical solution to the technical problem solved by this utility model is as follows:

[0008] This application provides a cigarette pack QR code recognition device, including a side pack replenishment device, a cigarette pack output turret, a scanner, and an auxiliary light source. The side pack replenishment device includes a side pack replenishment library and a pusher plate assembly. The bottom of the side pack replenishment library has a pusher plate channel. The pusher plate assembly includes a pusher plate with a reading window adapted to the QR code on the cigarette pack. The station inside the cigarette pack output turret corresponding to the pusher plate channel is a shooting station. The auxiliary light source is located on the horizontal left side of the shooting station. The scanner is located outside the pusher plate channel, and the scanning lens of the scanner is aligned with the QR code mark at the reading window. The scanner reads the QR codes of cigarette packs moving normally within the shooting station and replenished cigarette packs falling from the side pack replenishment library and pushed into the shooting station by the pusher plate.

[0009] As an improvement to the above solution, the pusher assembly further includes a cylinder that drives the pusher to move toward the side replenishment magazine.

[0010] As an improvement to the above solution, two reading windows are provided, which are symmetrically positioned on the side edge of the push plate. The positions of the reading windows correspond to the positions of the QR code markings on the surface of the cigarette pack.

[0011] Between the two reading windows, there is a part of the push plate structure that is a guide rod, which is attached to the connection between the upper and lower cigarette packs.

[0012] As an improvement to the above solution, the angle between the barcode scanner and the QR code plane on the cigarette pack is 70°, the angle between the auxiliary light source and the QR code plane on the cigarette pack is 45°, and the distance between the auxiliary light source and the QR code on the cigarette pack is 30mm.

[0013] As an improvement to the above solution, the auxiliary light source includes a light source bracket, LED beads, and a lampshade. The light source bracket is mounted on the packaging machine, the LED beads are mounted on the light source bracket, and the lampshade covers the LED beads.

[0014] As an improvement to the above solution, the light source bracket includes an adjustment plate and a mounting plate connected to each other. The adjustment plate has a strip-shaped adjustment hole. The light source bracket is connected to the packaging machine through the adjustment hole. The distance and angle of the lamp beads are adjusted by bolts that cooperate with the adjustment hole. The lamp beads are installed in the mounting plate. The lamp cover is clipped on the mounting plate and covers the outside of the lamp beads.

[0015] Compared with existing technologies, the above solution has the following advantages or beneficial effects:

[0016] This utility model realizes the reading of QR codes of cigarette packs during normal movement inside the cigarette pack output turret through a barcode scanner, and also realizes the reading of QR codes of cigarette packs falling into the replenishment station in the side replenishment warehouse. It realizes the reading of all small cigarette packs, simplifies the structure and operation process, and also solves the problem that it is not convenient to read the QR codes of cigarette packs inside the cigarette pack output turret due to the presence of the side sealing beauty container located on the left side of the cigarette pack output turret.

[0017] The auxiliary light source design eliminates the reflection caused by the transparent paper of the small box when the barcode scanner is directly illuminated, and also greatly reduces the impact of insufficient light on barcode scanning, ensuring clear barcode imaging and improving reading accuracy.

[0027] See Figure 1 and 2 This embodiment provides a cigarette pack QR code recognition device, including a vertical side pack replenishment device 2, a cigarette pack output turret 1, a barcode scanner 3, and an auxiliary light source 4. Under the action of the auxiliary light source 4, the barcode scanner 3 scans the QR codes on cigarette packs that are normally moving within the cigarette pack output turret 1 and the QR codes on cigarette packs replenished by the side pack replenishment device 2.

[0028] The aforementioned side pack replenishment device 2 includes a side pack replenishment magazine 21 and a pusher assembly. The bottom of the side pack replenishment magazine 21 has a pusher channel. The pusher assembly includes a pusher plate 22 and a cylinder 23 that drives the pusher plate 22 towards the side pack replenishment magazine 21. The pusher plate 22 has a reading window 221. The side pack replenishment magazine 21 clamps the vertically stacked cigarette packs, causing them to fall into the pusher channel under their own weight. The pusher assembly then pushes the falling cigarette packs from the pusher channel into the mold of the cigarette pack output turret 1 to complete the cigarette replenishment operation.

[0029] The aforementioned barcode scanner 3 is located on the outside of the pusher channel (on the side where cylinder 23 is located), and the scanning lens of the barcode scanner 3 is aligned with the QR code mark at the reading window 221. The station inside the cigarette pack output turret 1 directly opposite the pusher channel is the shooting station for cigarette pack QR code recognition. When cigarette replenishment is not required, there are no cigarette packs in the pusher channel, and the barcode scanner 3 can read the QR code of the cigarette packs that are moving normally inside the mold box of the cigarette pack output turret 1 through the reading window 221. This operation replaces the existing barcode scanner 3 reading the QR code of the cigarette packs at the second station of the cigarette pack output turret 1. When cigarette replenishment is required, two cigarette packs fall from the side replenishment compartment 21 and are pushed into the shooting station by the pusher assembly. The barcode scanner 3 can also read the QR codes of the two replenished cigarette packs through the reading window 221. This design uses a barcode scanner 3 to read the QR codes of cigarette packs that are moving normally inside the cigarette pack output turret 1, and also to read the QR codes of cigarette packs that are falling into the replenishment station inside the side replenishment box 21. This enables the reading of all small cigarette packs, simplifies the structure, and solves the problem that the presence of the side sealing container 5 on the left side of the cigarette pack output turret 1 makes it difficult to read the QR codes of cigarette packs inside the cigarette pack output turret 1.

[0030] See Figure 6 The auxiliary light source 4 is located on the horizontal left side of the shooting position of the cigarette pack output turret 1. Specifically, the angle between the barcode scanner 3 and the QR code plane on the cigarette pack is 70°, the angle between the auxiliary light source 4 and the QR code plane on the cigarette pack is 45°, and the distance between the auxiliary light source 4 and the QR code on the cigarette pack is 30mm. In the prior art, because the scanning light of the barcode scanner 3 needs to pass through the push plate channel to read the QR code on the cigarette pack, the space is small and the external light is insufficient; in addition, the adjustable range is limited when installing the barcode scanner 3, which means that when the light source of the barcode scanner 3 shines directly on the transparent paper of the small box on the surface of the cigarette pack, the paper of the small box has not been ironed and the shrink film is not completely flat. The direct light source has a certain probability of causing reflection, affecting the code reading and causing 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 barcode scanner 3 and fully reduce the impact of insufficient light on the scanning, ensuring that the barcode scanner 3 can form a clear image and read accurately.

[0031] In the embodiments described in this utility model, see [reference]. Figure 4Two reading windows 221 are provided, symmetrically positioned on the side edge of the push plate 22. The positions of the reading windows 221 correspond to the locations of the QR code markings on the cigarette pack surface, ensuring the QR code is exposed. This allows the scanner 3 to read the QR code markings through the reading windows 221. Between the two reading windows 221, a portion of the push plate 22 structure serves as a guide rod 222. The guide rod 222 fits against the connection between the upper and lower cigarette packs, providing guidance and ensuring the cigarette packs are smoothly pushed out of the push plate channel. This prevents uneven force on the cigarette packs during forward pushing, which could cause them to tilt and become stuck at the bottom of the side pack storage 21.

[0032] In the embodiments described in this utility model, the auxiliary light source 4 includes a light source bracket 41, LED beads, and a lampshade. The light source bracket 41 is mounted on the packaging machine, the LED beads are mounted on the light source bracket 41, and the lampshade covers the LED beads. The LED beads are Samsung LM281B+ PRO, a medium-power LED with high brightness, high luminous efficacy, and high color rendering index. The light source bracket 41 is made of aluminum alloy, which is lightweight, high-strength, corrosion-resistant, and heat-resistant, avoiding frequent replacement and maintenance and enhancing stability.

[0033] For further details, please refer to [link / reference]. Figure 4 and 5 The aforementioned light source bracket 41 includes a vertically connected adjustment plate 411 and mounting plate 412. The adjustment plate 411 has a strip-shaped adjustment hole 4111 through which the light source bracket 41 is connected to the packaging machine unit. The LED beads are installed inside the mounting plate 412, and a lampshade is secured to the mounting plate 412 and covers the outside of the LED beads. Specifically, the light source bracket 41 is connected to the packaging machine unit by bolts passing through the adjustment hole 4111. The distance between the LED beads and the QR code on the cigarette pack can be adjusted through the adjustment hole 4111, and the angle of the LED beads can also be adjusted by rotating the light source bracket 41 around the bolts.

[0034] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
