Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging technology, and in particular to a defective pack detection device for tobacco hard pack packaging machines and a tobacco hard pack packaging machine. Background Technology

[0002] To meet the quality control requirements of tobacco hard pack packaging production, and to ensure that defective packs can be detected in a timely manner to prevent them from entering subsequent production stages and affecting overall product quality and equipment operation, it is necessary to equip tobacco hard pack packaging machines with defective pack detection devices.

[0003] Currently, there are some defective package detection devices used to detect defective packages with changes in width. However, the detection rod is set horizontally and is close to the pin of the detection swing arm, which results in a small detection stroke. This cannot effectively amplify changes in the width of the defective package, causing defective packages to enter the feed wheel without being detected in time, leading to machine shutdown and damage to the feed wheel and related parts.

[0004] Therefore, there is an urgent need for a defective pack detection device for tobacco hard pack packaging machines. This device can solve the problem of missed detection of defective packs caused by the small detection stroke of existing detection devices, which cannot effectively amplify changes in the width of defective packs, and can achieve accurate identification of abnormal width dimensions of tobacco packs.

[0043] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] This embodiment discloses a defective package detection device 1 for a tobacco hard-pack packaging machine, such as... Figure 1 and Figure 2As shown, in this embodiment, the feeding roller 2 is located upstream of the feeding roller 3. The defective pack detection device 1 of the tobacco hard pack packaging machine is installed on the feeding roller 3. The defective pack detection device 1 of the tobacco hard pack packaging machine includes a lower guide plate 11, a cigarette pusher 12, a cigarette blocking limiter 13, a detection plate 14, and a sensor 15. The lower guide plate 11 is installed on the outside of the feeding roller 3 and parallel to the bottom surface of the feeding roller 3. The lower guide plate 11 is located between the feeding roller 3 and the feeding roller 2. The lower guide plate 11 is used to carry the cigarette packs. The space above the lower guide plate 11 is the detection station. The cigarette pusher 12 is installed on the feeding roller 2. The cigarette pusher 12 is used to push the cigarette packs to the detection station. The cigarette blocking limiter 13 is installed on the feeding roller 3. The cigarette blocking limiter 13 and the cigarette pusher 12 are arranged opposite to each other. The cigarette blocking limiter 13 is used to limit the cigarette packs to ensure that the cigarette packs are in the detection station. The detection plate 14 is located on the feeding roller. 3. A rotating connection is established. The detection plate 14 is positioned above the detection station and abuts against the cigarette pack. Sensors 15 are spaced above the detection plate 14 and are also positioned above the detection station. During the defective pack detection process of the tobacco hard box packaging machine, the cigarette pusher 12 on the feeding wheel 2 pushes the cigarette pack to the lower guide plate 11, which is located between the feeding wheel 3 and the feeding wheel 2, outside the feeding wheel 3, and parallel to the bottom surface of the feeding wheel 3, i.e., the detection station. Subsequently, the limiting and blocking cigarette device 13 on the feeding wheel 3, which is opposite to the cigarette pusher 12, limits the cigarette pack to ensure that the cigarette pack is stably positioned at the detection station. At this time, the detection plate 14, which is rotatably connected to the feeding wheel 3 and positioned above the detection station, abuts against the cigarette pack. At the same time, the sensors 15, which are spaced above the detection plate 14 and are also positioned above the detection station, detect the cigarette pack at this station, thus completing the defective pack detection process. When sensor 15 detects that the displacement signal of detection plate 14 exceeds the preset normal range, the package is considered defective; when sensor 15 detects that the displacement signal of detection plate 14 is within the preset normal range, the package is considered non-defective. This defective package detection device 1 for tobacco hard-pack packaging machines increases the detection range and stroke by coordinating the rotation of detection plate 14 with spaced sensors 15, effectively amplifying changes in the width of defective packages, reducing missed and false detections, improving the accuracy and reliability of defective package detection in tobacco hard-pack packaging machines, and ensuring the quality of tobacco package production.

[0045] Preferably, such as Figure 1 and Figure 2As shown, in this embodiment, the defective package detection device 1 of the tobacco hard box packaging machine also includes a pin 16. The left end of the detection plate 14 is rotatably connected to the right end of the feed wheel 3 through the pin 16. The pin 16 enables the rotatable connection between the left end of the detection plate 14 and the right end of the feed wheel 3, providing a stable and precise rotation fulcrum for the detection plate 14. This ensures that the detection plate 14 can rotate flexibly around the fixed fulcrum. When the tobacco package enters the detection station, the detection plate 14 can stably generate corresponding displacement based on the actual thickness of the tobacco package, with the pin 16 as the center. This avoids the detection plate 14 from shifting or shaking due to the non-fixed rotation fulcrum, thereby ensuring that the upper sensor 15 can accurately capture the displacement signal of the detection plate 14, further reducing the problems of missed detection and false detection caused by the unstable rotation of the detection plate 14.

[0046] Preferably, such as Figure 1 and Figure 2 As shown, in this embodiment, the defective package detection device 1 of the tobacco hard box packaging machine also includes a sensor bracket 17. The sensor bracket 17 is an L-shaped bracket. One folded edge of the L-shaped bracket is perpendicular to and connected to the top of the feed roller 3. The other folded edge of the L-shaped bracket is spaced apart from the detection plate 14 and parallel to the lower guide plate 11. The sensor 15 is installed on the folded edge of the L-shaped bracket that is parallel to the lower guide plate 11, so as to achieve stable and accurate positioning of the sensor 15. This ensures that the sensor 15 is always spaced apart at the preset detection position above the detection plate 14, forming a matching spatial layout with the detection plate 14, the lower guide plate 11 and the detection station. The stability of the L-shaped structure provides a reliable installation foundation for the sensor 15, avoiding positional displacement of the sensor 15 due to equipment vibration during the detection process. The clear structural connection relationship ensures that the interval distance and relative position between the sensor 15 and the detection plate 14 are constant, thereby ensuring that the sensor 15 can accurately capture the displacement signal of the detection plate 14. This further reduces the problems of missed detection and false detection caused by the positional deviation of the sensor 15, continuously improves the accuracy and reliability of defective package detection, and better guarantees the quality of tobacco package production. In other embodiments, the sensor bracket 17 may also be a U-shaped bracket or a Z-shaped bracket, etc.

[0047] Preferably, such as Figure 1 and Figure 2 As shown, in this embodiment, the defective pack detection device 1 of the tobacco hard pack packaging machine also includes a compression spring 18. The compression spring 18 is disposed between the sensor bracket 17 and the detection plate 14. The elastic force of the compression spring 18 can keep the detection plate 14 in stable contact with the tobacco pack at all times. Even if there are slight size fluctuations in the tobacco pack or small positional deviations during the conveying process, the detection plate 14 can still promptly adhere to the surface of the tobacco pack under the push of the compression spring 18, ensuring that the displacement change of the detection plate 14 can accurately reflect the actual width of the tobacco pack. In other embodiments, the compression spring 18 can be replaced by a spring sheet or a torsion spring, etc.

[0048] Preferably, such as Figure 1 and Figure 2 As shown, in this embodiment, the defective pack detection device 1 of the tobacco hard pack packaging machine also includes a buffer pad. The buffer pad is set on the side of the detection plate 14 facing the tobacco pack. The surface of the buffer pad is provided with anti-slip texture. The buffer pad can form a flexible contact when the detection plate 14 comes into contact with the tobacco pack, avoiding hard squeezing or scratching of the tobacco pack surface by the detection plate 14, effectively protecting the appearance of the tobacco pack. The anti-slip texture on the surface of the buffer pad can enhance the friction between the detection plate 14 and the tobacco pack, preventing the tobacco pack from being displaced or shifted at the detection station due to the rotation of the feed wheel 3, the pushing of the tobacco pusher 12, etc., ensuring that the tobacco pack is always stably in the preset detection position, thereby ensuring reliable contact between the detection plate 14 and the tobacco pack, so that the sensor 15 can accurately capture the displacement signal of the detection plate 14, reducing the missed detection and false detection caused by the position deviation of the tobacco pack, and further improving the accuracy and reliability of defective pack detection.

[0049] Preferably, such as Figure 1 and Figure 2 As shown, in this embodiment, the defective pack detection device 1 of the tobacco hard pack packaging machine also includes a signal amplifier 19 and a processor 110. The sensor 15 is electrically connected to the signal amplifier 19, and the signal amplifier 19 is electrically connected to the processor 110. This enables the displacement signal of the detection plate 14 detected by the sensor 15 to be first enhanced by the signal amplifier 19, and then the enhanced signal is transmitted to the processor 110. The processor 110 automatically and accurately compares and analyzes the signal with the preset normal range, and determines whether the cigarette pack is defective based on the comparison result. The complete signal processing and judgment process is as follows: The signal amplifier 19 can effectively amplify the weak displacement signal captured by the sensor 15, avoiding signal loss or misreading due to the original signal being too weak. The processor 110 can replace manual signal comparison and result judgment, which not only greatly improves the accuracy and efficiency of signal processing, but also further reduces the situation of missed detection and false detection.

[0050] Preferably, such as Figure 1 and Figure 2As shown, in this embodiment, the cigarette pusher 12 includes a cylinder 121, a first push rod 122, and a first push plate 123. The cylinder 121 is mounted on the feeding wheel 2. One end of the first push rod 122 is connected to the piston rod of the cylinder 121. The movement of the piston rod drives the first push rod 122 to move in the left-right direction. The first push plate 123 is connected to the opposite end of the first push rod 122. The first push plate 123 is adapted to the outer side of the cigarette pack. Under the action of the first push rod 122, the first push plate 123 can smoothly abut against the cigarette pack and push it precisely. The system ensures the cigarette pack is smoothly and accurately pushed to the inspection station. The first push plate 123, adapted to the outer side of the cigarette pack, prevents the pack from shifting, tilting, or being damaged during the pushing process. The stable power driven by the cylinder 121, combined with the directional movement of the first push rod 122, ensures the cigarette pack accurately enters the inspection station on the lower guide plate 11. This lays the foundation for subsequent limiting and blocking by the smoke-blocking component 13, the contact of the inspection plate 14 with the cigarette pack, and the detection by the sensor 15, further reducing missed or false detections caused by deviations in the cigarette pack's pushing position. In other embodiments, the cylinder 121 can be replaced by an electric cylinder or a hydraulic cylinder, etc.

[0051] Preferably, such as Figure 1 and Figure 2 As shown, in this embodiment, the limiting and blocking component 13 includes a second push rod 131 and a second push plate 132. The second push rod 131 extends in the left-right direction. One end of the second push rod 131 is connected to the feeding wheel 3. The second push plate 132 is connected to the opposite end of the second push rod 131. The second push plate 132 is adapted to the outer side of the cigarette pack. After the cigarette pack is pushed to the detection station, it abuts against the cigarette pack from the opposite direction to the pushing component 12. Together with the pushing edge component, it forms a bidirectional limiting, which can make the cigarette pack stably and accurately positioned at the detection station. This prevents the cigarette pack from leaving the preset detection range due to positional shift, shaking, or displacement during the detection process. This ensures that the subsequent detection plate 14 can stably abut against the cigarette pack and that the sensor 15 can accurately capture the displacement signal of the detection plate 14. This reduces the situation of missed detection and false detection caused by the position of the cigarette pack, and further improves the accuracy and reliability of the detection of defective cigarette packs in the tobacco hard box packaging machine.

[0052] Preferably, such as Figure 1 and Figure 2As shown, in this embodiment, the second push rod 131 is a telescopic structure. The second push rod 131 includes a fixed section, a telescopic section, and a locking bolt. The fixed section is connected to the feed wheel 3, and the telescopic section is sleeved inside the fixed section. The locking bolt is provided on the fixed section. The locking bolt passes through the side wall of the fixed section and abuts against the telescopic section. By loosening the locking bolt, the length of the telescopic section extending out of the fixed section can be adjusted to change the distance between the second push plate 132 and the detection station, so as to adapt to the limiting requirements of cigarette packs of different thicknesses. There is no need to replace the limiting components separately for cigarette packs of different specifications. This reduces the time cost of equipment adjustment and the cost of component replacement, and ensures that all types of cigarette packs can form a stable bidirectional limiting with the second push plate 132 and the cigarette pusher 12 during detection. This avoids limiting failure or position displacement due to differences in cigarette pack thickness, and further ensures the stable contact between the detection plate 14 and the cigarette pack and the accuracy of the displacement signal capture by the sensor 15.

[0053] like Figure 1 and Figure 2 As shown in the figure, this embodiment also discloses a tobacco hard box packaging machine. In this embodiment, the tobacco hard box packaging machine includes a feeding wheel 2, a feeding wheel 3, and a defective package detection device 1. The feeding wheel 2 is located upstream of the feeding wheel 3, and the defective package detection device 1 is installed on the feeding wheel 3, realizing a series of automated processes such as feeding, feeding, and defective package detection in tobacco hard box packaging. The feeding wheel 2 can transport the cigarette box raw materials to the feeding wheel 3, and the feeding wheel 3 is responsible for transporting the raw materials to the subsequent packaging process. The defective package detection device installed on the feeding wheel 3 can detect defective packages in a timely manner during the feeding stage. The automated feeding and feeding process can improve packaging efficiency and adapt to the needs of large-scale production. At the same time, the defective package detection device can detect unqualified products in a timely manner, reduce resource waste in subsequent processes, reduce manual picking costs, ensure the stability of final product quality, and improve product qualification rate.

[0054] Specifically, such as Figure 1 and Figure 2As shown, in this embodiment, the feeding wheel 3 includes a feeding support 31, a feeding rotating frame 32, and a feeding top cover plate 33. The limiting smoke-blocking component 13 is installed on the feeding support 31, and the feeding rotating frame 32 is rotatably installed on the feeding support 31. The feeding rotating frame 32 is used to carry and transport the smoke packs. The feeding top cover plate 33 is installed on the feeding rotating frame 32 and the feeding support 31. A connecting protrusion is provided on the right end of the feeding top cover plate 33, which is rotatably connected to the detection plate 14. The feeding support 31 provides installation support for the limiting smoke-blocking component 13, ensuring that the limiting smoke-blocking component 13 can be stably connected to the feeding component. The pusher 12 of wheel 2 works together to limit the cigarette packs at the inspection station. The feed frame 32 is rotatably mounted on the feed support 31, which can carry and transport the cigarette packs, ensuring the continuity of the cigarette pack transport before and after inspection. The feed cover plate 33 is mounted on the feed frame 32 and the feed support 31, which not only protects the feed frame 32 and other components, but also has an upward connecting protrusion on its right end that can be rotatably connected to the inspection plate 14, providing support for the stable rotation of the inspection plate 14 above the inspection station, so that the inspection plate 14 can smoothly contact the cigarette pack and work with the sensor 15 to complete the defective pack detection.
