Abstract
Description
Technical Field
[0001] This utility model relates to the field of cigarette box packaging technology, and in particular to a cigarette box appearance inspection device for YB55 packaging machine. Background Technology
[0002] Currently, the ZB25 / ZB45 small-pack packaging units widely used in the cigarette industry are equipped with visual appearance inspection devices in the main and auxiliary machine cigarette pack conveying channels and the YB55 inlet. These devices visually inspect the five sides of the rectangular or cubic cigarette pack: the front, back, top, bottom, and right sides. However, the left side of the cigarette pack is in constant contact with the conveyor belt and other equipment during processing, making it impossible for the currently installed cameras to capture images of this side. As a result, if packaging defects occur on this side, such as folded corners, exposed white material, dirt, damage, loose transparent paper, or belt misalignment, neither the equipment nor the operators can detect them in time. This leads to defective cigarette packs flowing into the next process, causing serious packaging quality problems. Utility Model Content
[0003] The purpose of this utility model is to provide a cigarette box appearance inspection device for the YB55 packaging machine, which solves the problem that the left side of the cigarette box cannot be visually inspected because it is in long-term contact with the conveyor belt and other equipment parts during the processing.
[0004] To achieve this objective, the present invention adopts the following technical solution: The present invention provides a cigarette box appearance inspection device for a YB55 packaging machine, including an inspection camera and a rejection device. It is installed in the cigarette box transparent paper heat-sealing channel and output turntable of the YB55 packaging machine. The output turntable has eight equally spaced stations arranged circumferentially, numbered sequentially from the first station to the eighth station along the counterclockwise rotation direction of the output turntable. In the transparent paper heat-sealing forming process of the YB55 packaging machine, a cigarette box transparent paper heat-sealing channel and a cigarette pusher are installed. The cigarette pusher is installed on the upper side of the cigarette box transparent paper heat-sealing channel and pushes the cigarette box into the first station of the output turntable. The rejection device is installed on the lower side of the third station of the output turntable. When the retraction rod on the rejection device retracts, the cigarette box falls. The rejection device is electrically connected to the controller of the YB55 packaging machine, and the controller is also electrically connected to the inspection camera. Projected along the rotation axis of the output turntable, the inspection camera is located inside the output turntable.
[0005] Preferably, the detection camera is mounted on the body of the YB55 packaging machine above the output turntable via a bracket.
[0006] Preferably, the YB55 packaging machine body is also equipped with a flashlight, which is directed toward the first station of the output turntable.
[0007] Preferably, a position sensor is installed on the front side of the cigarette pusher lever, the position sensor can detect the position of the cigarette pusher lever, and the position sensor is electrically connected to the controller.
[0008] Preferably, two sets of cigarette boxes are stacked in each workstation.
[0009] Preferably, the rejection device includes an electromagnet and the retractable rod, the electromagnet controls the movement of the retractable rod, a base plate is mounted on the retractable rod, and the cigarette box is supported on the base plate.
[0010] Preferably, a cigarette pack replenishment track is installed on the output turntable, the outlet of the cigarette pack replenishment track faces the fourth position of the output turntable, a cigarette box is installed inside the cigarette pack replenishment track, and clamping devices are installed on the two lower sides of the cigarette pack replenishment track. A cylinder controls the opening and closing of the clamping devices, and the cylinder is electrically connected to the controller.
[0011] Beneficial effects: An output turntable is installed at the rear end of the transparent paper heat-sealing forming process of the YB55 packaging machine. The output turntable has eight stations around its circumference. By installing an inspection camera above the output turntable, the left side of the cigarette box, which is in contact with the conveyor belt and other equipment during the pre-processing, can be photographed. This allows cigarette boxes with defects on the left side to be identified. When the defective cigarette box passes through the third station, the shrink rod on the rejection device retracts, causing the unqualified cigarette box to fall off. The inspection camera and rejection device enable rapid screening of unqualified cigarette boxes, ensuring the quality of cigarette box packaging. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0015] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0016] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0017] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0018] Under current technology, the left side of the cigarette box is in constant contact with the conveyor belt and other equipment during the processing, making it impossible to inspect the appearance of the left side with a camera. If the left side is damaged, it cannot be screened, resulting in damaged cigarette boxes being sold directly to the market, which in turn affects the market reputation.
[0019] To solve the above problems, such as Figure 1As shown, this utility model provides a cigarette box appearance inspection device for a YB55 packaging machine, including an inspection camera 1 and a rejection device. The YB55 packaging machine of this utility model includes a cigarette pack input section, a pull strap and transparent paper unfolding section, a transparent heat-sealing forming section, and an output section. The components involved in this utility model are installed in the cigarette box transparent paper heat-sealing channel 2 and the output turntable 3 of the YB55 packaging machine. The transparent heat-sealing forming section includes a heat-sealing forming wheel, the cigarette box transparent paper heat-sealing channel 2, and a cigarette pusher lever 4. The output section includes a cigarette pack rejection and replenishment conveying process, with the output turntable 3 responsible for the cigarette pack rejection and replenishment conveying. An output turntable 3 is installed in the feeding process. Eight equally spaced stations are arranged around the output turntable 3. They are numbered sequentially from the first station to the eighth station along the counterclockwise rotation direction of the output turntable 3. The cigarette pusher 4 is installed on the upper side of the cigarette box transparent paper heat sealing channel 2. The cigarette pusher 4 pushes the cigarette box 5 into the first station of the output turntable 3. The rejection device is installed on the lower side of the third station 31 of the output turntable 3. The retraction rod on the rejection device retracts, and the cigarette box 5 falls. The rejection device is electrically connected to the controller of the YB55 packaging machine. The controller is also electrically connected to the detection camera 1. The detection camera 1 is set inside the output turntable 3 by projection along the rotation axis of the output turntable 3.
[0020] On the YB55 production line, the output turntable of this utility model is equipped with a total of eight workstations. The workstation closest to the heat-sealing channel 2 of the cigarette box transparent paper is the first workstation. Then, seven workstations are arranged in sequence along the counterclockwise rotation direction of the output turntable 3, and are marked as the first workstation to the eighth workstation respectively. The rejection device is installed on the lower side of the third workstation 31. During the process of the cigarette box 5 entering the output turntable 3 from the transparent paper heat-sealing process, the end of the cigarette pusher 4 will push the cigarette box 5, so that the cigarette box 5 enters the first workstation on the output turntable. At the same time, after the pusher reaches the position, it triggers the position detection. The controller triggers the detection camera to take pictures, identify the packaging condition of the left side of the double stack of cigarette packs, and perform logic processing. If a defective cigarette pack is found, the defect mark inside the controller will be moved synchronously with the equipment and rejected at the third workstation 31. During rejection, the controller retracts the retracting rod of the rejection device, causing the cigarette boxes 5 on the rejection device to fall directly into the recycling box for collection. This prevents defective cigarette boxes 5 from entering subsequent packaging processes. Unqualified cigarette boxes 5 are then manually screened out, preventing cigarette packs with substandard packaging from entering the market and improving the final product quality. Furthermore, this invention only requires adding a detection camera 1, a flash 6, and a positioning sensor 7 to the YB55 packaging machine, resulting in minimal modifications to the machine and reduced modification costs.
[0021] The detection camera 1 is mounted on the YB55 packaging machine body above the cigarette pack rejection and replenishment conveying process on the output turntable 3 via a mounting bracket with two-axis rotation. The shooting angle of the detection camera 1 can be adjusted so that the left side of the cigarette box 5 can be directly photographed by the detection camera 1.
[0022] The YB55 packaging machine is also equipped with a flash 6, which faces the first position of the output turntable 3. Activating the flash 6 during shooting increases the amount of light entering the inspection camera 1, making the left side of the cigarette pack 5 more clearly visible in the camera's image. This allows for more rigorous screening of damaged cigarette packs 5 and improves the accuracy of damage detection. The flash 6 is mounted on the machine body via a dedicated bracket with adjustable hinges for both left-right and up-down angles, ensuring a clearer image of the left side of the cigarette pack.
[0023] A position sensor 7 is installed on the front side of the cigarette pusher lever 4. The position sensor 7 can detect the position of the cigarette pusher lever 4. The position sensor 7 is electrically connected to the controller. The cigarette pusher lever 4 pushes the cigarette boxes 5 into the first station in sequence. The cigarette boxes in the heat-sealing channel 2 of the cigarette box transparent paper move under the push of the cigarette pusher lever 4. When the position sensor 7 detects the position change of the cigarette pusher lever 4, it means that a new cigarette box has entered the first station. The change signal is sent to the controller, and the controller will directly activate the detection camera 1 to take a picture of the left side of the newly entered cigarette box 5, realizing the automated control of the picture taking process. The position sensor 7 can be installed on the YB55 packaging machine near the cigarette pusher lever 4 by bolt fixing, which can reduce the modification of the YB55 packaging machine and reduce the modification cost.
[0024] The output turntable 3 is equipped with eight workstations, with two sets of cigarette boxes 5 stacked in each workstation. The third workstation 31 is equipped with a rejection device that can reject unqualified cigarette boxes 5 downwards, allowing them to fall freely.
[0025] The rejection device includes an electromagnet and a retracting rod. The electromagnet controls the movement of the retracting rod, and a base plate is installed on the retracting rod. The base plate supports the cigarette box 5. When the detected problematic cigarette pack is transported to the base plate of station three, the controller controls the electromagnet to retract the retracting rod, causing the cigarette box 5 to lose the support of the base plate and fall down automatically.
[0026] A cigarette pack replenishment track 8 is installed on the output turntable 3. The outlet of the cigarette pack replenishment track 8 faces the fourth workstation. Cigarette boxes 5 are installed inside the cigarette pack replenishment track 8. Clamping devices are installed on both sides of the lower part of the cigarette pack replenishment track 8. The opening and closing of the clamping devices are controlled by a cylinder, which is electrically connected to the controller. Normal cigarette boxes 5 can be replenished through the cigarette pack replenishment track 8 to the empty workstation on the rejected output turntable 3, so that the YB55 packaging machine can process the cigarette boxes 5 subsequently.
[0027] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
