Description

Technical Field

[0001] This application relates to the field of tobacco machinery technology, and in particular to a defective product rejection device for a cigarette pack beautification system. Background Technology

[0002] In cigarette packaging, the cigarette pack beautifying container uses high-temperature ironing to ensure the smoothness of the cellophane. However, this process has a significant technical flaw: when the equipment malfunctions and stops or remains idle for an extended period, the cigarette packs remaining inside the beautifying container are continuously exposed to the heat-exposed iron plate at approximately 100°C. This causes the cellophane to deform due to heat, condensate, and even partially melt, resulting in quality defects such as yellow spots. When the packaging machine restarts, the cigarette packs are rapidly ejected at a rate of 3.2 packs per second. Failure to promptly remove defective packs will cause these heat-related defects (such as condensation inside the cellophane, surface depressions, and yellow spots) to directly flow into downstream processes, leading to batch quality incidents and additional rework costs.

[0003] In actual production, to solve the above problems, manual intervention and low-speed inching operation are mainly relied upon. For example, two operators are required to work together: one controls the equipment to run in low-speed inching mode, and the other visually inspects the appearance of the cigarette packs at the container outlet. However, manual inspection is inefficient and has many blind spots. When cigarette packs are transported in a 2×1 stack, the operator can only observe the top surface and sides of the stacked cigarette packs. The bottom surface and interlayer areas of the lower cigarette packs form a visual blind spot, which makes it impossible to effectively identify hidden defects such as packaging damage and torn transparent paper. At the same time, the inching mode significantly reduces the operating efficiency of the equipment, and the double manpower input significantly increases production costs.

[0004] Therefore, this application proposes a defective cigarette pack removal device for a cigarette pack beautification system, which can replace manual labor in removing defective cigarette packs and solve the technical problems of low efficiency and many blind spots in manual inspection. Utility Model Content

[0005] The main purpose of this application is to provide a defective product rejection device for a cigarette pack beautification system, which aims to solve the technical problems of low efficiency and many blind spots in manual inspection.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A defective product rejection device for a cigarette pack beautification system, the cigarette pack beautification system including a beautification container, and a first conveyor belt and a second conveyor belt respectively disposed upstream and downstream of the beautification container, the defective product rejection device comprising:

[0008] The front identification unit includes a first identification information collector located on one side of the first conveyor belt, used to acquire identification information of the side wall of the cigarette pack that is about to enter the beauty device;

[0009] The rear identification unit includes a second identification information collector located on the upstream side of the second conveyor belt, used to acquire identification information from the side wall of the cigarette pack that has just been removed from the beauty device;

[0010] The rejection unit includes a pusher plate, a drive component, and a connecting mechanism located on the downstream side of the second conveyor belt. The drive component is linked to the pusher plate through the connecting mechanism. In response to a signal indicating inconsistency between the identification information of the front identification unit and the rear identification unit, the drive component drives the pusher plate to move to the other side of the second conveyor belt to push the target cigarette pack away from the conveying path.

[0011] As a further improvement of this utility model, the front identification unit further includes a first sensor disposed on one side of the first conveyor belt for detecting the position signal of the cigarette pack reaching the first identification information collector; the rear identification unit further includes a second sensor disposed on one side of the second conveyor belt for detecting the position signal of the cigarette pack reaching the second identification information collector; the detection signals of the first sensor and the second sensor respectively trigger the start and stop of the first identification information collector and the second identification information collector.

[0012] As a further improvement of this utility model, the driving component is a telescopic cylinder, and the working end of the telescopic cylinder is connected to the push plate through a connecting mechanism; the connecting mechanism includes a rigid push rod, one end of which is coaxially connected to the working end of the telescopic cylinder, and the other end of which is connected to the side of the push plate facing away from the second conveyor belt; the axial direction of the telescopic cylinder is perpendicular to the transport direction of the second conveyor belt, and the moving path of the push plate is parallel to the top surface of the second conveyor belt; the telescopic cylinder performs work to push the push rod to extend and retract, causing the push plate to traverse the transport space of the second conveyor belt, so as to push the target cigarette pack away from the transport path.

[0013] As a further improvement of this utility model, the front identification unit further includes a first bracket, which is fixed to the side wall of the frame of the first conveyor belt, and its top end is provided with a mounting position for installing the first identification information collector and the first sensor; the rear identification unit further includes a second bracket, which is fixed to the side wall of the frame of the second conveyor belt, and its top end is provided with a mounting position for installing the second identification information collector and the second sensor; the connecting mechanism further includes a third bracket, which is fixed to the side wall of the frame of the second conveyor belt, and its top end is provided with a mounting surface for connecting to the telescopic cylinder flange.

[0014] As a further improvement of this utility model, the defective product rejection device further includes a signal processing circuit, which is electrically connected to the first identification information collector, the second identification information collector, the first sensor, the second sensor, and the telescopic cylinder. The signal processing circuit includes a hardware comparison module and a trigger module. The hardware comparison module is used to compare the output signals of the first identification information collector and the second identification information collector. The trigger module responds to the signal of inconsistency in the comparison result and outputs a drive level to the telescopic cylinder. The output signals of the first sensor and the second sensor are respectively connected to the power supply terminals of the first identification information collector and the second identification information collector through a level conversion circuit to control their start and stop.

[0015] The technical solution provided in this application may include the following beneficial effects:

[0016] In this application, before the cigarette pack enters the beauty container, the front-end identification unit collects and records its identification information. After the cigarette pack is removed from the beauty container, the rear-end identification unit collects the identification information of the same cigarette pack again. By comparing the consistency of the two sets of data, it is determined whether the cigarette pack was damaged during the beauty process due to heat deformation or mechanical compression (such as torn transparent paper or missing QR code area). If the data is inconsistent, it indicates that the cigarette pack is defective. The drive component of the rejection unit immediately responds to the signal and drives the push plate to move laterally through the connecting mechanism, accurately pushing the defective cigarette pack away from the conveying path to prevent it from flowing into downstream processes. Compared with manual sampling, the two independent scans of the cigarette pack side wall markings (before and after entering and leaving the beauty container), combined with the precise scanning triggered by the sensor, effectively solve the problem of missed detection caused by stacked cigarette packs being obstructed. Based on the hardware-linked dual data verification mechanism, it can identify marking damage caused by heat or mechanical damage, automatically rejecting defective products, significantly improving detection efficiency and accuracy, and reducing labor costs and batch quality risks.

[0029] Figure 1 This application illustrates an embodiment of a defective product rejection device for a cigarette pack beautification system. The cigarette pack beautification system includes a beautification container and a first conveyor belt and a second conveyor belt respectively disposed upstream and downstream of the beautification container; see also Figure 1 In this embodiment, the defective product rejection device includes: a front identification unit 1, a rear identification unit 2, and a rejection unit 3.

[0030] Among them, see Figure 1The front identification unit 1 includes a first identification information collector 11 located on one side of the first conveyor belt, used to acquire the identification information on the side wall of the cigarette pack about to enter the beauty device; the rear identification unit 2 includes a second identification information collector 21 located on the upstream side of the second conveyor belt, used to acquire the identification information on the side wall of the cigarette pack that has just been removed from the beauty device; the rejection unit 3 includes a push plate 31, a drive component 32, and a connecting mechanism 33 located on the downstream side of the second conveyor belt. The drive component 32 is linked to the push plate 31 through the connecting mechanism 33. In response to a signal indicating inconsistency between the identification information of the front identification unit 1 and the rear identification unit 2, the drive component 32 drives the push plate 31 to move to the other side of the second conveyor belt to push the target cigarette pack away from the conveying path. Before the cigarette pack enters the beauty device, the front identification unit 1 collects and records its identification information; after the cigarette pack is removed from the beauty device, the rear identification unit 2 collects the identification information of the same cigarette pack again. By comparing the consistency of the two sets of data, it is determined whether the cigarette pack was damaged during the beauty process due to heat deformation or mechanical compression (such as torn transparent paper or missing QR code area). If the data is inconsistent, it indicates that the cigarette pack is defective. The drive unit 32 of the rejection unit 3 immediately responds to the signal and drives the push plate 31 to move laterally through the connecting mechanism 33, accurately pushing the defective cigarette pack away from the conveying path and preventing it from flowing into the downstream process. Compared with manual sampling inspection, the two independent scans of the cigarette pack side wall markings (before and after entering and leaving the packaging container), combined with the precise triggering of the scan by the sensor, effectively solve the problem of missed detection caused by the obstruction of stacked cigarette packs; based on the hardware-linked dual data verification mechanism, it can identify the marking damage caused by heat or mechanical damage, automatically rejecting defective products, significantly improving detection efficiency and accuracy, and reducing labor costs and batch quality risks.

[0031] It should be noted that in actual production, the cigarette packs are stacked and transported in a 2×1 configuration during the beautification process. The identification information of the cigarette packs is placed on the side wall, and this position will not be obscured by the stacking.

[0032] Optionally, the first identification information collector 11 and the second identification information collector 21 can be configured as QR code scanners, wherein the first QR code scanner is installed on one side of the first conveyor belt, and is aligned with the QR code display area of ​​the cigarette pack about to enter the beauty device to perform an initial QR code scan and record the data; the second QR code scanner is installed on the upstream side of the second conveyor belt, and is also aligned with the QR code display area of ​​the cigarette pack being removed from the beauty device to perform a second scan; when the QR code information of the same cigarette pack scanned twice is inconsistent due to heat deformation or damage to the outer packaging, the drive component 32 immediately responds to the signal and pushes the push plate 31 to push the defective cigarette pack laterally away from the conveying path, thereby achieving automated and precise rejection.

[0033] Further, see Figure 1The front identification unit 1 also includes a first sensor 12 located on one side of the first conveyor belt, used to detect the position signal of the cigarette pack reaching the first identification information collector 11; the rear identification unit 2 also includes a second sensor 22 located on one side of the second conveyor belt, used to detect the position signal of the cigarette pack reaching the second identification information collector 21; the detection signals of the first sensor 12 and the second sensor 22 respectively trigger the start and stop of the first identification information collector 11 and the second identification information collector 21.

[0034] Optionally, the first sensor 12 and the second sensor 22 can be configured as through-beam photoelectric sensors. The first sensor 12 is installed on the side of the first conveyor belt. It generates a positioning signal by blocking the light path through the cigarette pack and triggers the first identification information collector 11 to scan the cigarette pack's identification information. The second sensor 22 is installed on the upstream side of the second conveyor belt. It detects that the cigarette pack has been removed from the packaging container and triggers the second identification information collector 21 to perform a secondary scan. Both sensors adopt an infrared light band anti-interference design. The signal directly controls the power supply of the collector, achieving a zero-delay response of "scanning as soon as it is in position". It accurately covers the top and bottom detection blind spots of the stacked cigarette packs, is suitable for high-speed conveying of 3.2 packs / second, and completely replaces the inefficiency and missed detection defects of manual visual inspection.

[0035] Further, see Figure 1 The driving component 32 is a telescopic cylinder, and the working end of the telescopic cylinder is connected to the push plate 31 through the connecting mechanism 33. The connecting mechanism 33 includes a rigid push rod, one end of which is coaxially connected to the working end of the telescopic cylinder, and the other end is connected to the side of the push plate 31 facing away from the second conveyor belt. The axial direction of the telescopic cylinder is perpendicular to the transport direction of the second conveyor belt, and the moving path of the push plate 31 is parallel to the top surface of the second conveyor belt. The telescopic cylinder performs work to push the push rod to extend and retract, causing the push plate 31 to cross the transport space of the second conveyor belt, so as to push the target cigarette pack away from the transport path.

[0036] Optionally, the drive unit 32 can be configured as a pneumatic telescopic cylinder, the cylinder body of which is directly fixed to the side wall of the frame of the second conveyor belt by bolts, and the axis of the telescopic rod is perpendicular to the conveyor belt transport direction; the working end of the telescopic rod is connected to one end of the rigid push rod through a universal joint, and the other end of the push rod is hinged to the back of the push plate 31 to ensure that the push plate 31 moves along a straight path parallel to the top surface of the conveyor belt; the pneumatic telescopic cylinder controls the air intake and exhaust through dual solenoid valves. In response to the signal of inconsistent identification information, the telescopic rod extends quickly, pushing the push plate 31 across the transport space of the conveyor belt to accurately push the defective cigarette packs away from the path. During the reset phase, the retraction is assisted by a spring. No external control unit intervention is required throughout the process, which is suitable for the high-speed rejection requirement of 3.2 packs / second.

[0037] Further, see Figure 1The front identification unit 1 also includes a first bracket 13, which is fixed to the side wall of the frame of the first conveyor belt, and its top is provided with a mounting position for installing the first identification information collector 11 and the first sensor 12; the rear identification unit 2 also includes a second bracket 23, which is fixed to the side wall of the frame of the second conveyor belt, and its top is provided with a mounting position for installing the second identification information collector 21 and the second sensor 22; the connecting mechanism 33 also includes a third bracket 34, which is fixed to the side wall of the frame of the second conveyor belt, and its top is provided with a mounting surface for connecting to the flange of the telescopic cylinder.

[0038] Furthermore, the defective product rejection device also includes a signal processing circuit, which is electrically connected to the first identification information collector 11, the second identification information collector 21, the first sensor 12, the second sensor 22, and the telescopic cylinder. The signal processing circuit includes a hardware comparison module and a trigger module. The hardware comparison module is used to compare the output signals of the first identification information collector 11 and the second identification information collector 21. The trigger module responds to the signal of inconsistency in the comparison result and outputs a drive level to the telescopic cylinder. The output signals of the first sensor 12 and the second sensor 22 are respectively connected to the power supply terminals of the first identification information collector and the second identification information collector through a level conversion circuit to control their start and stop.

[0039] Optionally, the signal processing circuit implements the comparison and rejection control of cigarette pack identification information based on a pure hardware architecture, and its operation method includes the following steps:

[0040] 1) Signal Input and Preprocessing

[0041] Step 1.1: The first sensor 12 detects that the cigarette pack has reached the scanning position of the first conveyor belt and outputs a high-level signal to the level conversion circuit;

[0042] Step 1.2: The level conversion circuit converts the high-level signal into a power trigger signal for the first identification information collector 11 through optocoupler isolation, starting its scanning of the cigarette pack identification and generating digital signal A;

[0043] Step 1.3: The second sensor 22 detects that the cigarette pack has moved out of the beauty container and reached the detection position of the second conveyor belt, and simultaneously triggers the second identification information collector 21 to scan the cigarette pack identification and generate digital signal B.

[0044] 2) Data comparison and logical judgment

[0045] Step 2.1: Digital signals A and B are input to the hardware comparison module through parallel data lines, and are compared bit by bit by the digital comparator chip (SN74LS85);

[0046] Step 2.2: If the two signals are consistent, the hardware comparison module outputs a low level; if there is a difference (such as a damaged QR code or missing data), it outputs a high-level abnormal signal.

[0047] 3) Triggering the culling action

[0048] Step 3.1: After the relay circuit of the trigger module receives a high-level abnormal signal, the coil is energized, the contacts close, and a 24V drive level is output to the solenoid valve of the pneumatic telescopic cylinder.

[0049] Step 3.2: The solenoid valve controls the extension rod of the pneumatic telescopic cylinder to extend, and pushes the push plate 31 across the second conveyor belt through the rigid push rod, pushing the defective cigarette pack away from the path;

[0050] Step 3.3: After the rejection is completed, the sensor detects the signal of the cigarette pack being removed, the relay is de-energized, the solenoid valve switches to exhaust, and the telescopic rod retracts to its original position under the action of the spring.

[0051] 4) Power Management and Interference Suppression

[0052] Step 4.1: Use a filter capacitor to eliminate high-frequency noise in the barcode scanner signal transmission;

[0053] Step 4.2: Transient Voltage Suppressor (TVS) diodes absorb surge voltages in the circuit to protect the hardware module.

[0054] In this embodiment, the first identification information collector 11 of the front identification unit 1 and the second identification information collector 21 of the rear identification unit 2 perform two independent scans on the side wall markings of the cigarette packs (before and after entering and leaving the packaging container), respectively. The scanning action is triggered by the sensor. The signal processing circuit compares the two data in real time. If they are inconsistent, it drives the pneumatic telescopic cylinder to move the push plate 31 laterally, accurately removing the defective products. Based on the fully automated "detection-comparison-rejection" process with pure hardware linkage, the problem of missed detection caused by the obstruction of stacked cigarette packs is completely solved. It is suitable for high-speed scenarios of 3.2 packs / second, significantly improving detection efficiency and accuracy, and preventing defective products from flowing into downstream processes.

[0055] It should be noted that the core of this embodiment lies in constructing a highly efficient automated rejection system for defective cigarette packs through the coordinated application of standard components in the prior art (first identification information collector 11, second identification information collector 21, first sensor 12, second sensor 22, telescopic cylinder, and signal processing circuit). The specific structures of the components (such as the optical module of the barcode scanner, the photoelectric element of the sensor, and the pneumatic valve of the telescopic cylinder) are all implemented using mature technologies known in the art, and their internal structure and manufacturing details have been widely disclosed in existing technical documents or commercial products, so they will not be described in detail here.

[0056] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by this application; the dimensions of the drawings are not related to the specific physical object, and the physical object dimensions can be arbitrarily changed.
