Description

Technical Field

[0001] This utility model relates to the field of tobacco pack processing technology, and in particular to a tobacco pack rejection device. Background Technology

[0002] Currently, the ZB45 packaging machine's cigarette pack rejection device used in tobacco manufacturing enterprises is mainly used to reject cigarette packs with quality defects such as missing inner frame paper, misaligned inner frame paper, and wrinkled aluminum foil paper (referred to as defective cigarette packs). However, it has been found in use that the existing rejection device frequently misses defective cigarette packs, leading to a decrease in the product qualification rate. Utility Model Content

[0003] The purpose of this invention is to solve the problem of low product qualification rate caused by the failure to remove defective cigarette packs in existing cigarette pack rejection devices. This invention provides a cigarette pack rejection device that can effectively remove defective cigarette packs, thereby improving the product qualification rate.

[0004] The applicant discovered through investigation that the existing cigarette pack rejection device has defects and misses some cigarette packs because:

[0005] The existing ZB45 packaging machine's cigarette pack rejection device uses an electromagnet to drive a mechanical linkage to reject defective cigarette packs. However, when the electromagnet operates at high frequency for extended periods, it is prone to problems such as overheating, weakening of suction force, and coil burnout, leading to malfunctions and shutdowns of the rejection device. This results in defective cigarette packs being missed, reducing the product pass rate.

[0006] To solve the above-mentioned technical problems, the present invention discloses a cigarette pack rejection device, comprising:

[0007] Mounting rack;

[0008] The cigarette pack conveyor is rotatably mounted on the mounting frame. Multiple fixing mechanisms are evenly spaced along the circumference of the cigarette pack conveyor. Each fixing mechanism is used to fix the cigarette pack. The cigarette pack conveyor can rotate intermittently around its own axis so that each fixing mechanism passes through the feeding station, the rejection station and the discharge station in sequence.

[0009] The cylinder is mounted on the mounting bracket and is connected to the air source. The cylinder's axis is parallel to the axis of the cigarette pack conveyor, and the cylinder's extended end is located at the rejection station.

[0010] The inspection agency is located upstream of the cigarette pack conveyor. The inspection agency is used to inspect the cigarette packs passing through its inspection end to confirm whether the cigarette packs are defective.

[0011] The control unit is electrically connected to the inspection mechanism. The control unit is used to control the cylinder to remove the defective cigarette pack when the defective cigarette pack detected by the inspection mechanism moves to the rejection station.

[0012] Using the above technical solution, when the inspection agency detects a defective cigarette pack, the control unit controls the cylinder extension end to extend, thereby removing the defective cigarette pack from the fixed mechanism located at the rejection station, thus improving the cigarette pack pass rate. This application uses a cylinder as the rejection element, which can reduce equipment failure rate, improve production efficiency, and reduce maintenance costs.

[0013] Optionally, each fixing mechanism includes a fixing plate extending radially along the cigarette pack conveyor tray, and each fixing plate has a notch for placing the cigarette pack; along the axial direction of the cylinder, the projection of the cylinder extension end falls into the notch of the fixing plate at the rejection station.

[0014] Optionally, a barb is provided on the inner wall of the end of the notch away from the cigarette pack conveyor tray, the barb being used to prevent the cigarette pack in the notch from detaching from the notch.

[0015] Optionally, the number of fixing mechanisms is eight, and the eight fixing mechanisms are equally spaced along the circumference of the tobacco pack conveyor, with the tobacco pack conveyor rotating 45° each time.

[0016] Optionally, it also includes a solenoid valve electrically connected to the control unit, which controls the operation of the cylinder through the solenoid valve.

[0017] Optionally, it also includes a feeding mechanism located upstream of the cigarette pack conveyor tray. The feeding mechanism is used to transport the cigarette packs to the feeding station so that the fixed mechanism located at the feeding station can pick up the cigarette packs from the feeding station.

[0018] Optionally, it also includes a discharge mechanism located at the discharge station. When any of the fixed mechanisms in the cigarette pack conveyor rotates to the discharge station, the discharge mechanism pushes the cigarette packs in the fixed mechanism located at the discharge station to the next process.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Currently, the ZB45 packaging machine's cigarette pack rejection device used in tobacco manufacturing enterprises is mainly used to reject cigarette packs with quality defects such as missing inner frame paper, misaligned inner frame paper, and wrinkled aluminum foil paper (referred to as defective cigarette packs). However, it has been found in use that the existing rejection device frequently misses defective cigarette packs, leading to a decrease in the product qualification rate.

[0031] The applicant discovered through investigation that the existing cigarette pack rejection device has defects and misses some cigarette packs because:

[0032] The existing ZB45 packaging machine's cigarette pack rejection device uses an electromagnet to drive a mechanical linkage to reject defective cigarette packs. However, when the electromagnet operates at high frequency for extended periods, it is prone to problems such as overheating, weakening of suction force, and coil burnout, leading to malfunctions and shutdowns of the rejection device. This results in defective cigarette packs being missed, reducing the product pass rate.

[0033] To solve the above technical problems, such as Figure 1 As shown, this utility model discloses a cigarette pack rejection device, including: a mounting frame 10, a cigarette pack conveying tray 20, a cylinder, a detection mechanism, and a control unit. These components work together to complete the conveying, detection, rejection, and output of qualified cigarette packs. The mounting frame 10 is used to fix the core components such as the cigarette pack conveying tray 20, the cylinder, and the detection mechanism, ensuring stable positioning and precise operation during operation. The cigarette pack conveying tray 20 is rotatably mounted on the mounting frame 10. Multiple fixing mechanisms 21 are evenly spaced along the circumference of the cigarette pack conveying tray 20, each used to fix a cigarette pack. The cigarette pack conveying tray 20 can rotate intermittently around its own axis, allowing each fixing mechanism 21 to pass sequentially through the feeding station (e.g., ...). Figure 1 As shown in area A), rejection station (such as...) Figure 1 (as shown in area B) and the discharge station (as shown in the middle area) Figure 1 As shown in area C, defective cigarette packs in the mixed cigarette packs are removed, and qualified cigarette packs are conveyed to the next process. A cylinder is mounted on the mounting frame 10 and connected to an air source. The cylinder's axis is parallel to the axis of the cigarette pack conveying tray 20, and the cylinder's extended end 30 is located at the rejection station. For example, the cylinder and mounting frame 10 are connected via a cylinder mounting seat to increase connection stability. The detection mechanism is a vision detection mechanism installed upstream of the cigarette pack conveying tray 20. It is used to perform real-time detection of cigarette packs passing through its detection end to accurately identify quality defects such as missing inner frame paper, displaced inner frame paper, and wrinkled aluminum foil paper, determining whether the cigarette pack is defective, and feeding the detection results back to the control unit (not shown in the figure). The control unit is electrically connected to the detection mechanism. When a defective cigarette pack detected by the detection mechanism moves to the rejection station, the control unit controls the extended end 30 of the cylinder to extend, thus removing the defective cigarette pack from the fixing mechanism 21 located at the rejection station.

[0034] Using the above technical solution, when the detection end of the inspection mechanism detects a defective cigarette pack, the control unit controls the extension end 30 of the cylinder to extend, thereby removing the defective cigarette pack from the fixed mechanism 21 located at the rejection station, thus improving the cigarette pack pass rate. This application uses a cylinder as the rejection element, which can reduce equipment failure rate, improve production efficiency, and reduce maintenance costs.

[0035] Optionally, such as Figure 1 As shown, each fixing mechanism 21 includes a fixing plate 211 extending radially along the cigarette pack conveyor 20. Each fixing plate 211 has a notch 212 for placing cigarette packs. Specifically, the cross-sectional area of ​​the notch 212 is less than or equal to the cross-sectional area of ​​the cigarette pack to ensure the cigarette pack is securely fixed. Furthermore, a barb 213 is provided on the inner wall of the end of the notch 212 facing away from the cigarette pack conveyor 20. The barb 213 can contact the side wall of the cigarette pack and is used to prevent the cigarette pack in the notch 212 from detaching from the notch 212, ensuring the stability of the cigarette pack conveying. Along the axial direction of the cylinder, the projection of the cylinder's extended end 30 falls into the notch 212 of the fixing plate 211 at the rejection station, ensuring that the rejection action is precisely applied to the cigarette pack in the notch.

[0036] Optionally, such as Figure 1 As shown, there are eight fixing mechanisms 21. The eight fixing mechanisms 21 are arranged at equal intervals along the circumference of the tobacco pack conveyor 20. The tobacco pack conveyor 20 rotates 45° intermittently each time so that the fixing mechanisms 21 pass through the feeding station, the rejection station and the discharge station in sequence.

[0037] Optionally, it also includes a solenoid valve (not shown in the figure), electrically connected to the control unit, which controls the operation of the cylinder through the solenoid valve. Furthermore, the control unit is electrically connected to both the detection mechanism and the solenoid valve. The control unit is responsible for receiving detection signals from the detection mechanism and controlling the opening and closing of the solenoid valve according to the signals, thereby controlling the operating state of the cylinder. Specifically, the cylinder is a single-acting cylinder. When the solenoid valve is energized, the cylinder's extended end 30 extends; when the solenoid valve is de-energized, the cylinder's extended end 30 retracts to its original position.

[0038] Optionally, a feeding mechanism (not shown in the figure) is also included, located upstream of the cigarette pack conveyor 20. The feeding mechanism is used to continuously convey the cigarette packs to the feeding station so that the fixing mechanism 21 located at the feeding station can accurately pick up the cigarette packs and fix them in the notch 212.

[0039] Optionally, it also includes a discharge mechanism (not shown in the figure), which is located at the discharge station. When the fixed mechanism 21 carrying the qualified cigarette pack rotates to the discharge station, the discharge mechanism is activated to push the cigarette pack in the fixed mechanism 21 located at the discharge station to the next process, thus completing the conveying of the qualified cigarette pack.

[0040] Optionally, the feeding station is located at Figure 1 The nine o'clock position in the diagram indicates that the workstation is located at... Figure 1 The discharge station is located at the six o'clock position. Figure 1 At the three o'clock position, the cigarette pack conveyor tray 20 rotates counterclockwise (e.g., Figure 1 (As indicated by the direction pointed to by the middle arrow T) Intermittent rotation.

[0041] Specifically, when the inspection agency detects a defective cigarette pack, the cigarette pack conveyor 20 receives the defective cigarette pack from the feeding station at the nine o'clock position, which is conveyed by the feeding mechanism. It then rotates counter-clockwise twice intermittently, moving the defective cigarette pack detected by the inspection agency to the six o'clock position. At this point, the extension end 30 of the control cylinder extends to remove the defective cigarette pack from the fixing mechanism 21 at the rejection station at the six o'clock position. The cylinder then retracts to its original position. When the inspection agency does not detect a defective cigarette pack, the cigarette pack conveyor 20 continues to rotate intermittently counter-clockwise. The fixing mechanism 21 receives a qualified cigarette pack from the nine o'clock position and moves it from the nine o'clock position to the six o'clock position, then to the three o'clock position. At this point, the discharge mechanism activates, pushing the qualified cigarette pack from the three o'clock position to the next process. Subsequently, the cigarette pack conveyor 20 continues to rotate, and the fixing mechanism 21 returns to the feeding station, entering the next cycle.

[0042] This application uses a cylinder instead of a traditional electromagnet as the rejection drive element, avoiding problems such as overheating, weakening of attraction force, and coil burnout that easily occur when electromagnets operate at high frequencies for extended periods. This reduces the equipment failure rate, solves the problem of missing defective cigarette packs, and ensures production continuity. The structure of this application is simple, the connections between components are reliable, maintenance costs are lower, and it is easy to promote and use.

[0043] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
