Description
Technical Field
[0001] This utility model relates to the field of cigarette production equipment technology, and in particular to a positioning device for coding cigarette boxes. Background Technology
[0002] The coding process is a crucial step in the cigarette box conveying process, its function being to code the packaged cigarette boxes. A cigarette box detection sensor detects when a box reaches the coding position, and a coding machine codes the box at that position. Afterwards, a scanner identifies and associates the QR code, and the boxes are sorted, completing the cigarette box conveying process. During production, due to the use of reusable cigarette boxes, differences in box size between different brands, and dynamic coding, the lack of a proper box positioning structure during coding can easily lead to defects such as skewed coding, wrinkles, and deviation from the target position. This results in unrecognizable QR codes, affecting subsequent QR code association and box sorting processes, disrupting the normal and orderly operation of production. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a positioning device for coding cigarette boxes, so as to achieve the reliability and stability of coding cigarette boxes and solve the problem of high coding defect rate in traditional coding cigarette boxes.
[0004] This utility model is achieved through the following technical solution: A positioning device for coding cigarette boxes includes a roller conveyor at the exit of a box-packing machine. A coding machine is mounted on the roller conveyor above the cigarette box conveying channel. The coding position is located at the corresponding part of the coding machine on the cigarette box conveying channel. The conveying direction of the cigarette box conveying channel is from back to front. The roller conveyor is equipped with a positioning device, which includes a longitudinal positioning mechanism positioned in front of the coding position. The longitudinal positioning mechanism includes a vertically extending positioning baffle. The positioning baffle is slidably mounted on the frame of the roller conveyor via a sliding installation structure and can slide vertically along the frame. A lifting drive structure drives the positioning baffle to rise and fall, causing the upper end of the positioning baffle to extend upwards above the cigarette box conveying channel or retract downwards below the cigarette box conveying channel, thereby achieving blocking, positioning, or release of the front side of the cigarette box on the cigarette box conveying channel.
[0005] As a preferred embodiment of the positioning device for marking cigarette boxes, the positioning device further includes a lateral positioning mechanism. The lateral positioning mechanism includes two sets of lateral positioning components arranged opposite each other on the left and right sides of the cigarette box conveying channel. Each set of lateral positioning components includes a positioning guide rod, which is mounted on the frame through a guide rod mounting structure. The positioning guide rods of the two sets of lateral positioning components respectively position and guide the left and right sides of the cigarette box in the cigarette box conveying channel.
[0006] As a preferred embodiment of the positioning device for marking cigarette boxes, the bottom of the positioning baffle is fixed to the slide rail plate. The sliding installation structure includes two sets of slider guide rail assemblies. The slide rail plate is mounted on the base plate through the two sets of slider guide rail assemblies. The base plate is mounted on the crossbeam of the frame through two corner pieces. The vertical plate of the corner piece is connected to the base plate. The horizontal plate of the corner piece has an oblong hole extending in the front-back direction. The corner piece is installed on the crossbeam by passing a bolt through the oblong hole and tightening it.
[0007] As a preferred embodiment of the positioning device for marking cigarette boxes, the lifting drive structure includes a lifting cylinder, the bottom of which is mounted on the frame via a lifting cylinder base plate, and the piston rod of the lifting cylinder extends upward and connects to the bottom of the positioning baffle.
[0008] As a preferred embodiment of the positioning device for marking cigarette boxes, the guide rod mounting structure includes multiple sets of guide rod mounting assemblies arranged at intervals along the front-back direction. Each set of guide rod mounting assemblies includes a pipe clamp, a rotating arm, and a base. The base is mounted on the frame and has a mounting cylinder. The rotating arm is inverted U-shaped. One end of the rotating arm is rotatably mounted in the inner hole of the mounting cylinder and locked by a first locking structure. The other end of the rotating arm is detachably mounted with a pipe clamp and locked by a second locking structure. The pipe clamp has a clamping groove for clamping the positioning guide rod.
[0009] As a preferred embodiment of the positioning device for marking cigarette boxes, the first locking structure includes a first locking screw and a lateral locking screw hole on the mounting cylinder. The first locking screw is screwed into the lateral locking screw hole of the mounting cylinder and pressed against the outer wall of the rotating arm to achieve the locking installation of the rotating arm and the mounting cylinder.
[0010] As a preferred embodiment of the positioning device for marking cigarette boxes, the second locking structure includes a second locking screw. The pipe clamp has an insertion hole for the downward insertion of the rotating arm end. The second locking screw is inserted upward into the insertion hole of the pipe clamp and tightened into the threaded hole at the end of the rotating arm to achieve the locking installation of the pipe clamp and the rotating arm.
[0011] This invention has the following advantages over the prior art: This utility model provides a positioning device for coding cigarette boxes. A retractable positioning baffle is installed in front of the coding position in the cigarette box conveyor channel. When coding is needed, the positioning baffle extends upwards to block and position the front of the cigarette box in the conveyor channel, allowing for static coding and ensuring the accuracy of the coding position. This, in turn, ensures the normal operation of subsequent QR code association and cigarette box sorting processes. After coding is completed, the positioning baffle retracts downwards without affecting the normal conveying of cigarette boxes in the conveyor channel. Furthermore, two sets of lateral positioning components on the left and right sides of the cigarette box conveyor channel, with positioning guide rods on each component, guide the left and right sides of the cigarette box in the conveyor channel, ensuring the accuracy of the coding position in both the front-back and left-right directions, further guaranteeing the reliability and stability of the coding process.

Detailed Implementation
[0017] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.
[0018] See Figures 1 to 4This embodiment discloses a positioning device for coding cigarette boxes. A roller conveyor 1 is provided at the outlet of the packing machine. A coding machine 2 is provided on the roller conveyor 1 above the cigarette box conveying channel. The part of the cigarette box conveying channel corresponding to the coding machine 2 is the coding position. The conveying direction of the cigarette box conveying channel is from back to front. A positioning device is provided on the roller conveyor 1. The positioning device includes a longitudinal positioning mechanism 3 set in front of the coding position. The longitudinal positioning mechanism 3 includes a vertically extending positioning baffle 4. The positioning baffle 4 is slidably installed on the frame of the roller conveyor 1 through a sliding installation structure and can slide vertically along the frame. The positioning baffle 4 is driven to rise and fall by a lifting drive structure, so that the upper end of the positioning baffle 4 extends upward above the cigarette box conveying channel or retracts downward below the cigarette box conveying channel, thereby blocking, positioning or releasing the front side of the cigarette box 6 on the cigarette box conveying channel.
[0019] The lifting drive structure includes a lifting cylinder 5. The bottom of the lifting cylinder 5 is mounted on the frame via a lifting cylinder base plate. The lifting cylinder base plate and the lifting cylinder 5, as well as the lifting cylinder base plate and the frame, can be connected by screws. The piston rod of the lifting cylinder 5 extends upward and connects to the bottom of the positioning baffle 4.
[0020] The bottom of the positioning baffle 4 is fixed to the slide rail plate 7 by screws. The sliding installation structure includes two sets of slider guide rail assemblies. The slide rail plate 7 is mounted on the base plate 10 by the two sets of slider guide rail assemblies. Each set of two slider guide rail assemblies includes a guide rail 8 and a slider 9 that slide in cooperation. The slider 9 of the two sets of slider guide rail assemblies is fixed to the slide rail plate 7 by screws. The lower section of the guide rail 8 of the two sets of slider guide rail assemblies is fixed to the base plate 10 by screws. The base plate 10 is mounted on the crossbeam 13 of the frame by two corner pieces 11. The vertical plate of the corner piece 11 is fixed to the base plate 10 by screws. The horizontal plate of the corner piece 11 has an oblong hole 12 extending in the front-back direction. Bolts are passed through the oblong hole 12 and tightened onto the crossbeam 13 to realize the installation of the corner piece 11 and the crossbeam 13. An oblong hole 12 is made on the horizontal plate of the corner piece 11. By adjusting the front and back positions of the bolts in the oblong hole 12, the position of the corner piece 11 relative to the crossbeam 13 in the front and back direction can be finely adjusted, thereby finely adjusting the position of the positioning baffle 4 in the front and back direction to meet the positioning requirements of cigarette boxes 6 of different brands.
[0021] The positioning device also includes a lateral positioning mechanism, which includes two sets of lateral positioning components 14 arranged opposite each other on the left and right sides of the cigarette box conveying channel. Each set of lateral positioning components 14 includes a positioning guide rod 15, which is mounted on the frame through a guide rod mounting structure. The positioning guide rods 15 of the two sets of lateral positioning components 14 respectively position and guide the left and right sides of the cigarette box 6 in the cigarette box conveying channel.
[0022] The guide rod mounting structure includes multiple sets of guide rod mounting assemblies arranged at intervals along the front-back direction. Each set of guide rod mounting assemblies includes a pipe clamp 16, a rotating arm 17, and a base 18. The base 18 can be mounted on the frame by screw connection. An mounting cylinder 19 is fixed on the base 18. The rotating arm 17 is inverted U-shaped. One end of the rotating arm 17 is rotatably mounted in the inner hole of the mounting cylinder 19 and locked by a first locking structure. The other end of the rotating arm 17 is detachably mounted with a pipe clamp 16 and locked by a second locking structure. The pipe clamp 16 is provided with a clamping groove for clamping the positioning guide rod 15.
[0023] The first locking structure includes a first locking screw 21. The mounting cylinder 19 has a lateral locking screw hole 20. The first locking screw 21 is screwed into the lateral locking screw hole 20 of the mounting cylinder 19 and pressed against the outer side wall of the rotating arm 17 to achieve the locking installation of the rotating arm 17 and the mounting cylinder 19.
[0024] The second locking structure includes a second locking screw 22. The pipe clamp 16 has an insertion hole for the end of the rotating arm 17 to be inserted downwards. The second locking screw 22 is inserted upwards into the insertion hole of the pipe clamp 16 and screwed into the threaded hole at the end of the rotating arm 17 to achieve the locking installation of the pipe clamp 16 and the rotating arm 17.
[0025] When it is necessary to adjust the left and right position of the positioning guide rod 15, first loosen the second locking screw 22 at the bottom of each pipe clamp 16 and remove each pipe clamp 16 and positioning guide rod 15 from each rotating arm 17. Then loosen the first locking screw 21 and rotate the rotating arm 17 around the inner hole of the mounting cylinder 19 in the horizontal plane, thereby adjusting the left and right position of the pipe clamp 16 installed at the other end of the rotating arm 17. After adjusting it into place, tighten the first locking screw 21. Then, install each pipe clamp 16 on the lower end of the corresponding rotating arm 17 and tighten each second locking screw 22 so that the positioning guide rod 15 always extends in the front and back direction before and after installation.
[0026] During operation, cigarette boxes 6 are output from the packing machine and enter the cigarette box conveying channel of the roller conveyor 1. Multiple conveying rollers at the bottom of the conveying channel rotate, driving the cigarette boxes 6 from back to front. During conveying, two positioning guide rods 15 on the left and right sides of the cigarette box 6 provide positioning guidance, ensuring the accuracy of the cigarette box 6's position in the left and right directions. When the detection sensor of the cigarette box 6 detects that the cigarette box 6 has reached the coding position, the lifting cylinder 5 actuates, causing the positioning baffle 4 to extend upwards above the conveying rollers, thus blocking and positioning the front side of the cigarette box 6 on the conveying channel, stopping the cigarette box 6. This facilitates the coding action of the coding machine 2. After coding is completed, the lifting cylinder 5 actuates, causing the positioning baffle 4 to retract downwards below the conveying rollers, allowing the cigarette box 6 to continue forward conveying. This embodiment changes the original dynamic coding method to a static coding method, ensuring the accuracy of the coding position of the cigarette box 6, significantly reducing maintenance and debugging time, and improving the reliability and stability of coding.
[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
