Description

TECHNICAL FIELD

[0001] The present application relates to the field of cigarette manufacturing, in particular to a cigarette state monitoring system for a cigarette and wrapper transparent paper packaging machine outlet conveying channel. BACKGROUND

[0002] After the cigarette and wrapper transparent paper packaging machine (CV machine) completes the wrapping of the cigarette, the CV machine will lift the cigarette by a second lifting push rod. The CV lifting push rod will lift one cigarette at a time. After the cigarette is lifted into position, the CV push rod will push the cigarette into a CV outlet cigarette conveying channel, where the end face of the cigarette will be sealed and shaped. The cigarettes in the CV outlet cigarette conveying channel will be sequentially arranged. The front cigarette will be pushed forward by the rear cigarette, and the cigarettes in the CV outlet cigarette conveying channel will be shaped in a CV outlet beauty container after the end face of the cigarette is sealed, thereby completing the CV packaging.

[0003] When the CV lifting push rod is not lifted into position (or the lifting into position detection fails), the channel is not clean (e.g., there is latex adhesion), and other factors cause the push rod to push the cigarette into the CV outlet cigarette conveying channel, the cigarette will be tilted, clamped, and turned upside down. Since there is no device or fault shutdown device in the CV outlet cigarette conveying channel to monitor the running state of the cigarette, as long as the equipment is running, the CV push rod will continue to push the cigarette into the CV outlet cigarette conveying channel, causing the abnormal cigarette in the CV outlet cigarette conveying channel to be clamped, tilted, and slide out of the CV outlet cigarette conveying channel, thereby causing quality problems of the cigarette, and there is a risk that the cigarette with quality problems will flow into the next process.

[0004] Currently, there is little research on the monitoring of the running state of the cigarette in the CV outlet cigarette conveying channel, and most of the research focuses on the rejection of defective cigarettes in the CV cigarette packaging machine, such as the rejection of cigarettes in the CV second lifter heat sealing timeout and the rejection of defective cigarettes in the CV outer packaging material, which is difficult to provide a reliable and effective idea for monitoring the running state of the cigarette in the CV machine. SUMMARY

[0005] In view of the above, the present application aims to provide a cigarette and wrapper transparent paper packaging machine outlet conveying channel cigarette state monitoring system to solve the problem that the existing packaging machine group cannot effectively monitor the posture of the cigarette when the CV push rod pushes the cigarette into the CV outlet cigarette conveying channel due to various factors of the CV machine.

[0006] The technical solution adopted by the present application is as follows:

[0007] The present application provides a cigarette and wrapper transparent paper packaging machine outlet conveying channel cigarette state monitoring system, which comprises a first sensor, a second sensor, a mounting bracket, a PLC, and an original machine control unit.

[0008] The first sensor and the second sensor are respectively installed on the mounting bracket, and the mounting bracket is arranged at a second lifting push rod of a transparent paper wrapper of a cigarette carton.

[0009] The first sensor and the second sensor are higher than a bottom surface of an outlet conveying channel of the transparent paper wrapper of the cigarette carton, and have a preset detection height relative to the bottom surface, and the first sensor and the second sensor have a preset horizontal included angle relative to the mounting bracket, so as to perform cross-type flat-scan detection on a surface of a cigarette rod in the outlet conveying channel.

[0010] The PLC is electrically connected with the first sensor, the second sensor and the original machine control unit respectively.

[0011] The original machine control unit is configured to send a second lifting push rod cigarette pushing to position signal to the PLC, and receive a level signal sent by the PLC to trigger an alarm output or stop.

[0012] In at least one possible implementation, the mounting bracket is arranged at a position of the push rod when the second lifting push rod pushes the cigarette to the position.

[0013] In at least one possible implementation, the first sensor and the second sensor are adjusted in rotation and inclination by screws connected with the mounting bracket.

[0014] In at least one possible implementation, the detection height is greater than a preset cigarette rod height and less than twice the cigarette rod height.

[0015] In at least one possible implementation, the mounting bracket is provided with a height adjusting mechanism.

[0016] In at least one possible implementation, the level signal output by the PLC is connected to a cigarette carton transparent paper wrapper lifting fault signal point of the original machine control unit.

[0017] In at least one possible implementation, the monitoring system further comprises an optoelectronic coupler, a level output end of the PLC is electrically connected with a control end of the optoelectronic coupler, and the optoelectronic coupler is configured to deliver a level signal to the original machine control unit.

[0018] In at least one possible implementation, the first sensor and the second sensor are laser sensors or photoelectric detection switches.

[0019] The main design concept of the present application is to monitor the running state of the cigarette rod in the CV outlet conveying channel, and to detect the cigarette rod in the CV outlet conveying channel by using two sensors with a certain height and a preset horizontal angle. Specifically, by setting an installation bracket at the CV second lifting push rod and installing two sensors on the bracket, the running state and surface of the cigarette rod of multiple specifications and sizes are monitored, and the detection signal is associated with the CV second lifting fault access point of the original machine control unit, that is, the cigarette rod state monitoring in the CV outlet conveying channel is integrated into the original machine control, so that the abnormal warning output and triggering of the cigarette rod running state can be realized, the probability of defective products and production cost can be reduced, and the product quality guarantee capability of the equipment can be improved.

[0020] Especially, the flat scanning of the cigarette rod in the CV channel can also detect the surface quality of the cigarette rod, reduce the quality problems caused by oil seal folding or unpacking, and thus greatly reduce the product quality risk of the cigarette rod, and prevent quality problem products such as unpacking and folding of the transparent paper of the cigarette rod from flowing into the next process. BRIEF DESCRIPTION OF DRAWINGS

[0021] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described below in combination with the drawings, in which:

[0022] Figure 1 A structural schematic diagram of a cigarette rod transparent paper packaging machine outlet conveying channel cigarette rod state monitoring system provided by an embodiment of the present application is shown. DETAILED DESCRIPTION

[0023] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the drawings, in which the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be interpreted as a limitation on the present application.

[0024] The present application proposes an embodiment of a cigarette rod transparent paper packaging machine outlet conveying channel cigarette rod state monitoring system, specifically as shown in Figure 1 which includes: a first sensor 1, a second sensor 2, an installation bracket 3, a PLC, and an original machine control unit (from the control system of the original packaging machine CV machine);

[0025] The first sensor 1 and the second sensor 2 are respectively installed on the installation bracket 3, and the installation bracket 3 is arranged at the CV push rod, specifically can be arranged at the position of the CV push rod when the CV push rod of the original machine pushes the cigarette rod to the position, and the installation bracket 3 is arranged.

[0026] The first sensor 1 and the second sensor 2 are higher than the bottom surface of the CV outlet conveying channel and have a preset detection height relative to the bottom surface, and the first sensor 1 and the second sensor 2 have a preset horizontal included angle (such as 45°) relative to the mounting bracket 3, so as to perform cross-type flat scanning detection on the surface of the cigarette in the CV outlet conveying channel.

[0027] The PLC is electrically connected with the first sensor 1, the second sensor 2 and the original machine control unit respectively.

[0028] The original machine control unit is used for sending a CV push rod cigarette pushing to position signal to the PLC, that is, the CV push rod cigarette pushing to position signal of the original machine can be used as a detection trigger condition, for example, the flat scanning detection signal of the two sensors is acquired by the PLC once every time the cigarette is pushed.

[0029] In addition, the original machine control unit is also used for receiving the trigger alarm output or trigger stop electric level signal sent by the PLC, and it can be understood that the original machine control unit itself is provided with an alarm mechanism and a stop mechanism, so that the PLC only provides a trigger signal for the above-mentioned mechanism of the original machine control unit. In actual operation, the electric level signal output by the PLC can be connected to the CV lifting fault signal point of the original machine control unit.

[0030] Based on the foregoing embodiment, the working mode of the monitoring system is schematically described as follows: after the cigarette is lifted to position by the CV second lifting push rod, the two sensors installed at the CV cigarette push rod detect whether the cigarette in the CV outlet conveying channel appears abnormal postures such as tilting and overturning through flat scanning. In addition, the flat scanning of the sensors can also realize the detection of the surface quality of the normally conveyed cigarette in the CV channel. Specifically, in the packaging production process, there are many factors causing the cigarette in the CV outlet conveying channel to have problems such as wrinkle, fold and oil seal scattering. The flat scanning of the surface of the cigarette in the CV outlet conveying channel can realize effective detection of the above-mentioned surface packaging quality defects of the cigarette.

[0031] Further, since the size of the same model and type of cigarette is fixed, the length L, width W and height H of the cigarette are generally L>W>H, and when abnormal operation occurs, the height of the cigarette in the CV outlet conveying channel will be doubled, equal to the width and other abnormal sizes greater than H due to overlapping, cutting, overturning and other postures.

[0032] Based on this, the vertical height H0 of the first sensor and the second sensor can be set relative to the CV outlet conveying channel bottom surface plane, and in order to enable the sensor to reliably detect the abnormal cigarette posture in the CV channel (such as the cigarette being in an abnormal state of left tilt, right tilt, overturning, etc.), the sensor vertical height needs to be greater than H and less than 2H (i.e. H < H0 < 2H), so as to achieve full coverage detection of the cigarette in the CV outlet conveying channel; at the same time, in order to detect the surface quality of the cigarette in the CV outlet conveying channel, the height of the bracket can be adjusted so that the sensor height H0 can be adjusted within the detection range, and the sensitivity adjustment of the surface quality detection of the cigarette in the CV outlet conveying channel is realized.

[0033] From the above concept, the first sensor and the second sensor are adjusted in rotation and inclination by the screw connected with the mounting bracket.

[0034] In addition, the detection height is preferably between a preset cigarette height and two cigarette heights, and in order to realize the setting of the detection height, in some preferred embodiments, the mounting bracket 3 is provided with a height adjustment mechanism (such as a telescopic lifting device, which is a mature mechanical technology and will not be described and limited herein), so as to realize the adjustment of the sensor detection sensitivity and the monitoring of the running state of the cigarette of multiple specifications in the CV channel.

[0035] In addition, in some preferred embodiments, the monitoring system further comprises an optoelectronic coupler, the optoelectronic coupler is installed in the same electrical control cabinet as the PLC, the level output end of the PLC is electrically connected with the control end of the optoelectronic coupler, and the optoelectronic coupler transmits signals to the original machine control unit.

[0036] Finally, in combination with the above embodiments, it can also be supplemented that the first sensor 1 and the second sensor 2 adopt laser sensors or photoelectric detection switches, so that whether the running state of the cigarette in the CV outlet conveying channel is abnormal can be determined by whether the emitted light is blocked.

[0037] For example, if the sensor emitted light is blocked by foreign matter, it indicates that the posture of the cigarette in the CV channel is abnormal, and in actual operation, only the emitted light of one sensor is blocked, the state of the cigarette in the channel can be determined to be abnormal, and only when the emitted light of both sensors is not blocked, it can be indicated that the state of the cigarette in the channel is normal. Of course, the above detection mechanism is only illustrative, and those skilled in the art can design a corresponding abnormal detection strategy as needed based on the system architecture provided by the present application, which will not be described herein.

[0038] As for the alarm, shutdown and display mode, it can also be flexibly set, and the following illustrative description is provided for reference:

[0039] When the abnormal state of the cigarette in the channel is detected, the PLC can count and send a first high-level signal representing the abnormal state of the cigarette to the original machine control unit, and the original machine control unit and its display screen are used to realize monitoring and alarm output of the running state of the cigarette.

[0040] If the PLC continuously receives a preset number (such as 3 times) of cigarette abnormal signals, the PLC can send a second high-level signal for triggering shutdown to the original machine control unit (in actual operation, the second high-level signal can be integrated into the original machine CV lifting fault signal point), and the original machine control unit and the display screen are used to realize device shutdown control, alarm output and other functions.

[0041] In summary, the main design concept of the present application is to monitor the running state of the cigarette in the CV outlet conveying channel, and to use two sensors with a certain height and a preset horizontal angle to perform flat scanning detection on the cigarette in the CV outlet conveying channel. Specifically, by setting an installation bracket at the CV second lifting push rod and installing two sensors on the bracket, the running state and surface of the cigarette of multiple specifications and sizes are monitored, and the detection signal is associated with the CV second lifting fault input point of the original machine control unit, that is, the cigarette state monitoring in the CV outlet conveying channel is integrated into the original machine control, so that abnormal alarm output and triggering shutdown of the cigarette running state can be realized, the probability of defective products and production cost can be reduced, and the product quality assurance capability of the equipment can be improved.

[0042] Especially, flat scanning of the cigarette in the CV channel can also detect the surface quality of the cigarette, reduce the quality problems caused by oil seal folding or unpacking, and thus greatly reduce the product quality risk of the cigarette, and prevent quality problem products such as unpacking and folding of the transparent paper of the cigarette from flowing into the next process.

[0043] In the embodiment of the present application, "at least one" means one or more, and "multiple" means two or more. "And / or" describes the association relationship of the associated objects, which means that there can be three kinds of relationships, for example, A and / or B, which can represent the existence of A alone, the existence of A and B at the same time, and the existence of B alone. Wherein A and B can be singular or plural. The character " / " generally represents an "or" relationship between the front and rear associated objects. "At least one of the following" and similar expressions mean any combination of these items, including any combination of single or multiple items. For example, at least one of a, b and c can represent: a, b, c, a and b, a and c, b and c, or a and b and c, wherein a, b, and c can be single or multiple.
