Detailed Implementation

[0015] like Figure 1-5 As shown, this utility model provides a packaging machine carton shortage detection device, including a support platform 1, an infeed conveyor belt 2, a weighing mechanism 3, and an outfeed conveyor belt 4 arranged sequentially on the support platform 1, a rejection mechanism 5 arranged on one side of the outfeed conveyor belt 4, and a smoke receiving box 6 arranged on the other side of the outfeed conveyor belt 4. The weighing mechanism 3 includes a support frame 7 arranged on the support platform 1, a support base 8 arranged on the support frame 7, a positioning groove 9 arranged on the upper end of the support base 8, a support boss 10 arranged in one end of the positioning groove 9, and a weighing sensor arranged in the positioning groove 9. 11. A support column 12 erected on the upper end of the load cell 11, a weighing plate 13 erected on the upper end of the support column 12, and a protective cover 14 erected on the upper end of the support base 8 and covering the load cell 11; one lower end of the load cell 11 is fixed to the support boss 10 in the positioning groove 9, and the upper side of the other end of the load cell 11 is fixed to the lower end of the support column 12. The protective cover 14 has a box-shaped structure with an open lower end and a clearance opening at the upper end. The upper end of the support column 12 passes through the clearance opening of the protective cover 14 and is fixed to the lower end of the weighing plate 13.

[0016] The feeding conveyor belt 2 corresponds to the discharge conveyor mechanism of the packaging machine. After the cigarette packs come out of the packaging machine, they enter the feeding conveyor belt 2 and are successively conveyed by the feeding conveyor belt 2 to the weighing mechanism 3 for weighing. After the cigarette packs on the weighing mechanism 3 are weighed, they enter the discharge conveyor belt 4 under the push of the next cigarette pack. On the discharge conveyor belt 4, the rejection mechanism 5 rejects the cigarette packs that are found to be missing packages. The qualified cigarette packs are conveyed to the next process via the discharge conveyor belt 4.

[0017] The rejection mechanism 5 uses an existing structure, consisting of a rejection cylinder and a rejection head fixed on the telescopic end of the rejection cylinder. The rejection cylinder is on one side of the discharge conveyor belt 4, and the telescopic end extends out to push the smoke strips on the discharge conveyor belt 4 into the smoke receiving box 6 on the other side of the discharge conveyor belt 4 through the rejection head, thus completing the rejection.

[0018] The weighing mechanism 3 weighs the cigarette packs. The support frame 7 is fixed to the support platform 1 between the feeding conveyor belt 2 and the discharging conveyor belt 4, and is used to support and fix other components. The weighing sensor 11 is a single-point weighing sensor. During installation, the weighing sensor 11 is placed into the positioning groove 9 at the upper end of the support base 8. One end of the weighing sensor 11 is fixed to the support boss 10 in the positioning groove 9, and the other positions do not contact the inner wall of the positioning groove 9. The other end of the weighing sensor 11 is in a cantilevered state. The lower end of the support column 12 is fixed to the upper side of the cantilevered end of the weighing sensor 11, and the upper end of the support column 12 is fixed to the lower end of the weighing tray 13. The cigarette packs are weighed when they stop on the weighing tray 13, and the weighing accuracy is high.

[0019] This device can continuously complete feeding, weighing, and discharging. When in use, it is placed between the discharge end of the original packaging machine and the conveyor belt that transports the material to the next process. It does not require any modification to the structure of the packaging machine itself, and its structure is not complicated. It has high weighing accuracy and can be used with different models of packaging machines.

[0020] like Figure 1-2 As shown, the upper surface of the feeding end of the weighing pallet 13 is provided with an anti-slip groove 15, and the upper surface of the discharging end is a plane.

[0021] Multiple anti-slip grooves 15 are provided on the upper surface of the feeding end of the weighing pallet 13 to slow down the cigarette stick when it enters the weighing pallet 13, ensuring that the cigarette stick can stay on the weighing pallet 13 for weighing. The upper surface of the discharging end of the weighing pallet 13 is a smooth plane, which ensures that the cigarette stick can smoothly enter the discharging conveyor belt 4 under the pushing of the next cigarette stick.

[0022] like Figure 1 , 2As shown in Figure 5, the support platform 1 is also equipped with a positioning detection mechanism. The positioning detection mechanism includes a gantry frame 16 on the support platform 1, a first positioning sensor on the gantry frame 16, a cantilever rod 17 on the gantry frame 16, and a second positioning sensor on the cantilever end of the cantilever rod 17. The first positioning sensor is vertically aligned with the weighing pallet 13. One end of the cantilever rod 17 is fixed to the gantry frame 16, and the other end extends horizontally above the discharge conveyor belt 4. The second positioning sensor is vertically aligned with the discharge conveyor belt 4.

[0023] Both the first and second positioning sensors are photoelectric sensors. The first positioning sensor can detect whether there is a smoke bar at the corresponding position on the weighing pallet 13, and the second positioning sensor can detect whether there is a smoke bar at the corresponding position on the discharge conveyor belt 4, thereby realizing the automated control of the weighing mechanism 3 and the rejection mechanism 5.

[0024] like Figure 1-2 As shown, the first positioning sensor includes a first transmitter 18 mounted vertically downwards on the gantry 16 and a first receiver 19 mounted on the support 8 facing the discharge conveyor belt 4. The weighing pallet 13 has a clearance opening, through which the first transmitter 18 and the first receiver 19 are vertically aligned. This design provides convenient installation positions for the first transmitter 18 and the first receiver 19, ensuring that other components do not interfere with the positioning detection of the first positioning sensor.

[0025] like Figure 1 , 5 As shown, the discharge conveyor belt 4 includes a fixed base plate 20 mounted on a support platform 1, a left support 21 and a right support 22 mounted on the fixed base plate 20, a left drive wheel set 23 and a right drive wheel set 24 mounted inside the left support 21 and the right support 22 respectively, a left belt 25 and a right belt 26 mounted on the left drive wheel set 23 and the right drive wheel set 24 respectively, a bearing seat and a drive motor 27 mounted on the fixed base plate 20, a shaft 28 rotatably mounted on the bearing seat, and a transmission belt 29 between the drive end of the drive motor 27 and the shaft 28. The drive motor 27 drives the shaft 28 to drive on the bearing seat via the transmission belt 29. The two ends of the shaft 28 are respectively connected to the left drive wheel set 23 and the right drive wheel set 24. The left belt 25 and the right belt 26 are spaced apart. The upper ends of the left belt 25 and the right belt 26 are on the same plane and are lower than or level with the upper surface of the weighing support plate 13.

[0026] The discharge conveyor belt 4 uses two parallel narrow belts, namely the left belt 25 and the right belt 26. The two ends of the cigarette stick are placed on the two narrow belts respectively to achieve conveying. The drive motor 27 drives the shaft 28 on the shaft seat to rotate through the transmission belt 29. One wheel in the left drive wheel set 23 and one wheel in the right drive wheel set 24 are respectively connected to the two ends of the shaft 28. The rotation of the shaft 28 can drive the left belt 25 and the right belt 26 to rotate in the left drive wheel set 23 and the right drive wheel set 24 respectively to realize the conveying of the cigarette stick. The structure is simple, easy to disassemble and assemble, and makes the installation and use of the second positioning sensor more convenient.

[0027] like Figure 1 , 5 As shown, the second positioning sensor includes a second transmitter 30 mounted on the cantilever end of the cantilever rod 17 and a second receiver mounted on the fixed base plate 20 and corresponding to the second transmitter 30. The second receiver is not shown in the figure; it is sufficient as long as its position corresponds to the second transmitter 30 and there are no other objects between them. The second transmitter 30 corresponds to the second receiver via the left belt 25 and the right belt 26. The installation positions of the second transmitter 30 and the second receiver are provided, making installation more convenient and ensuring that other components do not affect the positioning detection of the second positioning sensor.

[0028] like Figure 1 , 2 As shown, a discharge tray 32 is provided between the left support 21 and the right support 22, and the discharge tray 32 is provided with an avoidance opening corresponding to the second transmitter 30.

[0029] The two ends of the discharge tray 32 are located inside the left belt 25 and the right belt 26 respectively, to prevent the cigarette stick from falling into the discharge conveyor belt 4, causing malfunctions and safety hazards, and the clearance does not interfere with the function of the second positioning sensor.
