Description

Technical Field

[0001] This utility model belongs to the field of QR code reading technology, and in particular to a QR code reading device for cigarette packs. Background Technology

[0002] With the rise of the Internet of Things (IoT) industry, the "one item, one code" technology has gained attention from many industries. Now, more and more tobacco companies are introducing QR codes into cigarette packaging. However, when reading the QR codes on cigarette cartons, the cartons are transported by a conveyor belt, causing them to be in motion during the scanning process. This makes it difficult to focus the scan, resulting in false detections and missed detections, which in turn requires re-reading the code, thus reducing the efficiency of reading QR codes on cigarette cartons.

[0003] A Chinese patent (authorization announcement number CN211359690U) discloses a barcode scanning and error prevention device, which includes: "a workbench, with support columns at the four corners of the bottom of the workbench, and support plates arranged in a matrix at the four corners of the top of the workbench. Rollers are provided between the two support plates on the left and between the two support plates on the right, and a conveyor belt is sleeved between the two rollers."

[0004] It is evident that the cited patent documents suffer from the problem of being difficult to focus, which can easily lead to false positives and false negatives. Utility Model Content

[0005] The purpose of this invention is to provide a QR code reading device for cigarette packs to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a QR code reading device for cigarette packs, comprising a reading base, an inverted U-shaped mounting frame mounted on the top surface of the reading base, two upright plates symmetrically welded to the top surface of the mounting frame, a rotating shaft rotatably connected to the opposite side of the two upright plates via pins, two pull ropes wound around the circumference of the rotating shaft via two winding rollers, four vertical plates symmetrically welded to the top surface of the mounting frame, a limit roller rotatably connected to the opposite side of every two vertical plates, two pull ropes passing over the two limit rollers respectively, the free ends of the two pull ropes passing through the mounting frame and connected to a connecting block, a stop block for limiting the position of the cigarette packs connected between the two connecting blocks, a conveyor belt for moving the cigarette packs provided in the inner cavity of the reading base, and a drive assembly for driving the rotating shaft to rotate mounted on the top surface of the mounting frame.

[0007] Preferably, the inner top surface of the mounting bracket is equipped with multiple barcode scanners for scanning the QR codes on cigarette packs, and the drive assembly includes transmission gears, a mounting base, a drive motor, and half gears.

[0008] Preferably, one end of the rotating shaft extends through one side of the upright plate, and the transmission gear is connected and fixed to the end of the rotating shaft that extends through one side of the upright plate.

[0009] Preferably, the mounting base is mounted on the top surface of the mounting frame, and the drive motor is mounted on one side of the mounting base.

[0010] Preferably, the half gear is fixedly connected to the output shaft of the drive motor, and the half gear meshes with the transmission gear.

[0011] Preferably, one of the upright plates has a through hole on one side for the rotating shaft to pass through, and the inner cavity of the through hole is provided with a bearing.

[0012] Preferably, the outer wall of the bearing is connected and fixed to the inner wall of the through hole, and the circumference of one end of the rotating shaft passes through the bearing and is connected and fixed to the inner wall of the bearing.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This cigarette QR code reading device, by rotating the shaft, can retract two pull ropes, which can pull the stop block to move longitudinally, so that the cigarette pack can be pressed against the stop block, allowing the reader to read the QR code. Compared with the existing devices for reading cigarette QR codes, this device can read the code when the cigarette pack is stationary, avoiding the difficulty of focusing when the cigarette pack is moving, and improving the efficiency of reading cigarette codes.

[0015] The drive components provide power for the rotation of the shaft, enabling it to wind up the rope. The two symmetrically welded vertical rods restrict the movement of the stop block, preventing deviation during longitudinal movement. Attached Figure Description

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] like Figures 1 to 5 The illustrated cigarette QR code reading device includes a reading base 1, an inverted U-shaped mounting frame 2 mounted on the top surface of the reading base 1, and a conveyor belt 10 for moving cigarette packs within the inner cavity of the reading base 1. Personnel place the cigarette packs to be read in a regular manner on the surface of the conveyor belt 10, allowing the conveyor belt 10 to move the cigarette packs into the mounting frame 2. Multiple barcode scanners 18 for scanning the QR codes of cigarette packs are mounted on the inner top surface of the mounting frame 2, and the barcode scanners 18 can read the QR codes of the cigarette packs that have entered the mounting frame 2.

[0028] The top surface of the mounting frame 2 is symmetrically welded with two upright plates 3. The opposite side of the two upright plates 3 is rotatably connected to a rotating shaft 4 via a pin. Two take-up rollers are used to wind up two pull ropes 5 around the circumference of the rotating shaft 4. By rotating the rotating shaft 4, the two take-up rollers can be driven to rotate, thereby winding up the two pull ropes 5.

[0029] Four vertical plates 6 are symmetrically welded to the top surface of the mounting frame 2. Each pair of vertical plates 6 has a limit roller 7 rotatably connected to one of their opposite sides. Two pull ropes 5 pass over the two limit rollers 7 respectively. The free ends of both pull ropes 5 pass through the mounting frame 2 and are connected to connecting blocks 8. A stop block 9 for limiting the position of the cigarette packs is connected between the two connecting blocks 8. A counterweight is installed on the bottom surface of each of the two connecting blocks 8. By rotating the rotating shaft 4, the two pull ropes 5 can be wound up by two winding rollers. Because the two pull ropes 5 pass over the two limit rollers 7 respectively, both pull ropes 5 are inverted L-shapes. This causes the wound pull ropes 5 to move upwards via the connecting blocks 8, and the stop block 9 is located on one side of the conveyor belt 10. After the stop block 9 moves upward, it will be on one side of the cigarette pack. The cigarette pack will be pressed against the stop block 9 by the movement of the conveyor belt 10, thereby restricting the position of the cigarette pack. This prevents the cigarette pack from being read in a prohibited state, avoiding the difficulty of focusing when reading the code while it is in motion, and improving the efficiency of reading the code of the cigarette pack. After the code is read, the rotating shaft 4 is released, and the weight of the counterweight will drive the stop block 9 and the connecting block 8 to move downward. When the connecting block 8 moves downward, it will pull the pull rope 5, which will drive the take-up roller and the rotating shaft 4 to rotate in the opposite direction. This allows the stop block 9 to move below the conveyor belt 10, so that the conveyor belt 10 can carry the read cigarette pack to move and discharge it from the code reading base 1 for collection.

[0030] The top surface of the mounting bracket 2 is equipped with a drive assembly for driving the rotating shaft 4 to rotate. The drive assembly includes a transmission gear 11, a mounting base 12, a drive motor 13, and a half gear 14. One end of the rotating shaft 4 extends through to one side of the upright plate 3. The transmission gear 11 is connected and fixed to the end of the rotating shaft 4 that extends through to one side of the upright plate 3. The mounting base 12 is mounted on the top surface of the mounting bracket 2. The drive motor 13 is mounted on one side of the mounting base 12. The half gear 14 is connected and fixed to the output shaft of the drive motor 13. The half gear 14 meshes with the transmission gear 11. By turning on the drive motor 13, the half gear 14 can be driven to rotate. Because the half gear 14 meshes with the transmission gear 11, when the half gear 14 rotates... The drive gear 11 rotates, which in turn drives the shaft 4 to rotate, providing power for the rotation of the shaft 4. This, in turn, causes the winding rope 5 to move the connecting block 8 and the stop block 9 upward. When the teeth on the periphery of the half gear 14 disengage from the drive gear 11, the restriction on the shaft 4 is lifted, allowing the connecting block 8 and the stop block 9 to move downward via the counterweight. This pulls the rope 5, causing the winding roller, shaft 4, and drive gear 11 to rotate in the opposite direction. When the teeth on the periphery of the half gear 14 re-engage with the drive gear 11, the shaft 4 rotates again, which in turn drives the connecting block 8 and the stop block 9 upward again, restricting the position of the cigarette pack. By repeating this operation, the position of the cigarette pack can be repeatedly restricted.

[0031] Two vertical rods 15 are symmetrically welded to the inner bottom surface of the code reading base 1. Two connecting blocks 8 are slidably sleeved on the periphery of the two vertical rods 15, so that when the two connecting blocks 8 move longitudinally, they will move on the periphery of the two vertical rods 15, allowing the vertical rods 15 to restrict the movement trajectory of the two connecting blocks 8 and the stop block 9, and to prevent deviation.

[0032] One of the upright plates 3 has a through hole 16 on one side for the rotating shaft 4 to pass through. The inner cavity of the through hole 16 is equipped with a bearing 17. The outer side wall of the bearing 17 is connected and fixed to the inner side wall of the through hole 16. The circumference of one end of the rotating shaft 4 passes through the bearing 17 and is connected and fixed to the inner side wall of the bearing 17. When the transmission gear 11 drives the rotating shaft 4 to rotate, the rotating shaft 4 will drive the inner ring of the bearing 17 to rotate, thereby allowing the bearing 17 to support the rotating shaft 4 and also assist in the rotation.

[0033] Working principle:

[0034] The QR code reading device for cigarettes places the cigarettes to be read on the surface of the conveyor belt 10 and moves it into the mounting frame 2. At this time, the drive motor 13 is turned on, which drives the half gear 14 to rotate. Since the half gear 14 meshes with the transmission gear 11, the rotation of the half gear 14 will drive the transmission gear 11 to rotate, thereby driving the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 will cause the two take-up rollers to take up the pull rope 5, so that the two take-up pull ropes 5 will drive the stop block 9 to move upward through the connecting block 8, allowing the stop block 9 to move to one side of the cigarette pack. The cigarette pack will then be conveyed through the conveyor belt 10. The moving conveyor belt 10 presses against the stop block 9, thereby restricting the position of the cigarette pack and preventing the cigarette pack from being read. Since the half gear 14 only has half of its teeth, when the teeth of the half gear 14 disengage from the transmission teeth 11, it can move downwards by the weight of the stop block 9 itself, allowing the stop block 9 to move below the conveyor belt 10. This allows the conveyor belt 10 to move the read cigarette pack and discharge it from the reading base 1 for collection, avoiding the difficulty of focusing when reading the code while the cigarette pack is in motion and improving the efficiency of reading the code on the cigarette pack.
