Description

Technical Field

[0001] The utility model relates to a two-dimensional code scanning and adjusting device for cigarette storage, belonging to the technical field of cigarette storage code scanning. Background Art

[0002] In cigarette logistics, the incoming cigarettes process at the logistics center requires scanning the QR code of each incoming cigarette. Since the QR code scanner is a beam-type scanner, it needs to be placed on both sides of the incoming conveyor line to scan the codes of the conveyed cigarettes. However, with the increase in the number of cigarette product specifications and the increasing variation in cigarette box sizes, the current fixed scanner support cannot meet the scanning requirements of different cigarette models. Due to factors such as scanning distance and lighting, the scanner often fails to recognize the cigarette code due to focus and reflection problems, resulting in serious missed codes during incoming scanning. Research and improvement are necessary. Utility Model Content

[0003] Based on the above, the present invention provides a device for scanning and adjusting a two-dimensional code for cigarette storage to overcome the shortcomings of the prior art.

DETAILED DESCRIPTION

[0018] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] See also Figures 1 to 3In this embodiment, a QR code scanning and adjustment device for cigarette storage includes a storage unit and an adjustment unit. The storage unit includes a conveyor 11 and a code reader 12. The adjustment unit includes a distance sensor 21, a column 22, an X-axis guide rod 23, an X-axis screw rod 24, an X-axis guide block 25, and an X-axis motor 26. Two distance sensors 21 are installed on both sides of the conveyor 11 and are located upstream of the code reader 12. The column 22 is installed on both sides of the conveyor 11. Two X-axis guide rods 23 and an X-axis screw rod 24 are installed between the tops of the columns 22. The X-axis screw rod 24 is a bidirectional screw rod. Both sides of the X-axis screw rod 24 are threadedly connected to the X-axis guide block 25, and the X-axis guide block 25 is movably sleeved on the X-axis guide rod 23 to limit the movement of the X-axis guide block 25. The X-axis motor 26 is connected to the X-axis screw rod 24. The code reader 12 is installed below the X-axis guide block 25 and moves with the X-axis guide block 25.

[0020] Workers unload cigarette boxes from trucks onto the middle of conveyor 11. As the cigarettes move forward, they are first detected by distance sensor 21, which transmits this information to the controller. The controller, based on a preset program (e.g., distance value X, and code reader 12's reading distance Y, controlled to ensure X and Y are equal), controls the rotation of X-axis motor 26, driving X-axis lead screw 24 to move the two X-axis guide blocks 25 closer or farther away from each other. This adjusts the position of code reader 12 relative to the cigarette box, enabling scanning of different cigarette models as they enter the warehouse. It should be noted that the QR code on the cigarette box is located on the left or right side of the cigarette. By placing code reader 12 on both sides, it is possible to prevent the QR code from being missed.

[0021] In order to facilitate reliable scanning of cigarette boxes at different heights, light curtain sensors 33 are installed on both sides of the conveyor 11. The light curtain sensor 33 is located upstream of the code reader 12, so that the height of the cigarette box can be detected. A follower block 27, a Z-axis guide rod 28, a Z-axis screw rod 29, a Z-axis guide block 30, a Z-axis motor 31 and a fixed block 32 are installed at the bottom of the X-axis guide block 25. The follower block 27 is installed at the bottom of the X-axis guide block 25, two Z-axis guide rods 28 and one Z-axis screw rod 29 are installed between the follower block 27 and the fixed block 32, the Z-axis guide block 30 is threadedly connected to the Z-axis screw rod 29, the Z-axis guide block 30 is movably sleeved on the Z-axis guide rod 28, the Z-axis motor 31 is connected to the Z-axis screw rod 29, and the code reader 12 is installed on the side of the Z-axis guide block 30.

[0022] The height information of the cigarette box is detected by the light curtain sensor 33 and the detection information is transmitted to the controller. The controller controls the rotation of the Z-axis motor 31 according to the preset program, drives the Z-axis screw 29 to rotate and move the Z-axis guide block 30 up and down, thereby adjusting the height position of the code reader 12 to realize the scanning of different types of cigarettes entering the warehouse.

[0023] The working principle of the above-mentioned cigarette storage QR code scanning and adjustment device is as follows:

[0024] Workers lower the cigarette boxes from the truck to the middle of the conveyor 11. As the cigarettes move forward, the distance sensor 21 and the light curtain sensor 33 respectively detect the distance from their side to the code reader 12, as well as the height information of the cigarette box. The detection information is transmitted to the controller, which controls the X-axis motor 26 to rotate according to the preset program, driving the X-axis screw 24 to rotate and move the two X-axis guide blocks 25 away from or closer to each other, thereby adjusting the horizontal position of the code reader 12 from the cigarette box. At the same time, the Z-axis motor 31 rotates and drives the Z-axis screw 29 to rotate and move the Z-axis guide block 30 up and down to adjust the height position of the code reader 12, so as to realize the scanning of different types of cigarettes entering the warehouse to avoid missing scans.

[0025] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
