Description

Technical Field

[0001] The present invention relates to the technical field of cigarette quality detection, and more specifically, to a quality detection device for a strip box cellophane wrapping machine. Background Art

[0002] As the last packaging process of the GDX1 packaging unit, the working stability of the YB95 strip box cellophane wrapping machine is directly related to various indicators such as the output, quality, and consumption of cigarettes. When the push rod of the output device pushes the strip box towards the outlet direction, the vertical moving iron of the cigarette beautifier is in a non-working state and is higher than the top height of the cigarette strip, facilitating the cigarette strip to enter the interior of the beautifier. When the push rod is in the return state, the vertical moving iron of the cigarette beautifier is in the working state, and the iron is 0.3 mm lower than the height of the cigarette strip to perform shaping and beautification on it. The qualified cigarette strips are transported through the cigarette strip elevator and enter the packing machine process.

[0003] During the operation of the YB95 wrapping machine, when there are abnormalities in the upstream strip box packaging, such as the output turntable of the patch packer and the cigarette pack output mechanism not operating in coordination, resulting in a single pack in the conveying channel of the cigarette pack supply system, misalignment occurs during the process of the strip box paper and the 2*5 cigarette packs being pushed by the CT push rod, and the cigarette strip position in the cigarette strip forming and conveying channel is offset, causing appearance deformation during the first elevator and horizontal pushing processes. During the cigarette strip cellophane wrapping process, problems such as cigarette strip deformation, loose strips, cellophane wrinkles, and adhesion of adjacent cigarette strip cellophanes are likely to occur due to reasons such as high static electricity of the cellophane, unstable cellophane conveying, poor cutter cutting, improper temperature setting of the long-sealing heating iron of the cellophane. When the above cigarette strips pass through the height at the bottom of the non-working state of the iron, they will be blocked at the entrance of the cigarette strip elevator. If the defective cigarette strips cannot be removed by manual in time, the cigarette strips will be arranged in sequence in the conveying channel until they reach the beautifier, and until the output channel is full of cigarette strips, the cigarette strips will be continuously pushed out of the output channel and fall to the ground, resulting in local severe deformation. The operation of the YB95 wrapping machine will not stop until manual control or the pushing resistance of the push rod is relatively large. If the loosely wrapped cigarette strips pass through the cigarette beautifier and are pushed by the cylinder from the end of the elevator to the vertically downward channel, blockage will also occur, and it is necessary to manually dredge and close the cigarette strip elevator of the corresponding unit. The machine platform personnel need to manually pack the cigarette strips. After the conveying channel of the packing machine operates normally, the manually packed cigarette strips are added to the channel at the entrance of the cigarette strip elevator again. When the height of a certain cigarette strip exceeds the height at the bottom of the non-working state of the iron, during the process of the push rod pushing the cigarette strip by one position, it will collide with the surface of the iron of the cigarette beautifier, resulting in shutdown, causing the cigarettes in the 12 cigarette strips between the first position of the output channel and the cigarette beautifier to be bent and wrinkled to varying degrees. Moreover, a high frequency of collisions will cause misalignment of the push rod stroke, and at the same time, the collision will generate a rigid impact on the transmission components of the machine, exacerbating the wear of the components.

DETAILED DESCRIPTION

[0027] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0028] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0030] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0031] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0032] according to Figure 1 As shown, the present invention provides a quality detection device for a cigarette box transparent paper packaging machine, including a push rod 2, a conveying channel 1, a through-beam optical fiber sensor 3, a height detector, a cigarette strip beauty device 8, a sticking detector, a cigarette strip lifter 11 and a controller. The controller is electrically connected to the aforementioned components, and can control the start and stop of the conveying channel 1. The through-beam optical fiber sensor 3 and the sticking detector are respectively connected to the amplifier and then to the input end of the controller, and the output end of the controller is connected to the buzzer and the shutdown program port. In addition, a reset switch is also provided on the controller to contact the alarm state.

[0033] The push rod 2 is located at the starting end of the conveying channel 1, and is used to push the cigarette rod 4 wrapped with transparent paper into the conveying channel 1. The optical fiber sensor 3 is located on both sides of the front section of the conveying channel 1, and is used to detect the appearance quality of the cigarette rod 4.

[0034] The height detector is arranged above the conveying channel 1 and behind the opposing optical fiber sensor 3, and is used to detect the height of the tobacco rod 4; the tobacco rod beautifier 8 is arranged behind the height detector, and the tobacco rod beautifier 8 is provided with a soldering iron 9, which is used to heat and flatten the transparent paper on the tobacco rod 4.

[0035] The adhesion detector is located at the rear section of the conveying channel 1 and is used to detect whether there is adhesion between adjacent tobacco rods 4 .

[0036] The cigarette bar elevator 11 is located at the end of the conveying channel 1 and is used to lift the fully inspected cigarette bars 4 to the next process; when the cigarette bars 4 fail to pass the detection of the opposed fiber optic sensors 3, height detectors, and adhesion detectors, the controller can issue an alarm.

[0037] The quality inspection device for the carton cellophane wrapping machine provided by the present invention can reduce the shutdown frequency of the YB95 carton cellophane wrapping machine during actual operation, has a partial early warning function for the appearance quality inspection of the cigarette bars 4, delays the service life of the transmission components of the push rod 2, reduces the material consumption of the unit, shortens the time for the operator to handle faults, and improves the operation efficiency of the equipment. The opposed fiber optic sensors 3 detect the height of the cigarette bars 4 in the conveying channel 1 of the cigarette bars 4. When a deformed cigarette bar 4 or a cigarette bar 4 with poor cellophane wrapping is found, its electrical signal is transmitted to the controller, and the controller activates the pneumatic alarm program. While the equipment continues to run remotely, the operator is prompted to take it out.

[0038] When the cigarette bar 4 is intermittently pushed to the height detector on the front side of the cigarette bar beautifier 8, if the deformed height of the cigarette bar 4 exceeds the height of the non-working surface of the soldering iron 9 of the cigarette bar beautifier 8, the controller will trigger the shutdown program of the YB95 wrapping machine, and the conveying channel 1 will stop running. There is an adhesion detector in the conveying channel 1 after the outlet of the cigarette bar beautifier 8. If adjacent cigarette bars 4 are adhered to each other, the buzzer will alarm again, prompting the operator that the cigarette bars 4 may be blocked at the entrance of the cigarette bar elevator 11.

[0039] Further, the conveying channel 1 includes a smooth section, an inclined section, and a buffer section connected in sequence. The inclined section slopes downward at a certain angle, and the smooth section and the buffer section are horizontally arranged; the opposed fiber optic sensors 3, height detectors, and cigarette bar beautifiers 8 are arranged on the smooth section, the adhesion detector is arranged on the inclined section, and the cigarette bar elevator 11 is arranged at the end of the buffer section. During implementation, when the cigarette bars 4 are conveyed on the smooth section and are heat-treated and sorted by the cigarette bar beautifier 8, it is impossible to directly detect whether there is adhesion between the cellophanes of adjacent cigarette bars 4. In the present invention, the middle part of the conveying channel 1 is set as an inclined section. When the cigarette bar 4 enters the inclined section from the smooth section, it can obtain a sudden acceleration under the action of its own weight. At this time, if the cigarette bar 4 located at the rear is not adhered to this cigarette bar 4, this cigarette bar 4 can independently slide down along the inclined section; otherwise, two or more cigarette bars 4 will slide down along the inclined section at the same time, and the adhesion detector can detect the specific number of adhered cigarette bars according to the time situation.

[0040] Furthermore, the cigarette pack is constrained by the guide rail in the left and right directions perpendicular to the flow direction in the plane where the process flow is located, and the cigarette pack is pushed forward along the flow direction by the push rod 2 and the like. Its deformation is due to the resistance along the forward direction, so the final deformation of the cigarette pack will be reflected in the direction perpendicular to the plane where the cigarette pack is located, thereby causing the action of the detection device of the present invention. The number of the opposing optical fiber sensors 3 is at least one pair, and the two opposing optical fiber sensors 3 are symmetrically arranged on both sides of the conveying channel 1; when the cigarette rod 4 enters the conveying channel 1, the deformed cigarette rod 4 can cut off the opposing optical fiber path between the opposing optical fiber sensors 3, so that the controller issues an alarm. When the cigarette rod 4 that is normally squeezed and deformed passes through the opposing optical fiber sensor 3, its height cannot reach the height required to cut off the opposing optical fiber path, so it will not trigger the alarm of the controller.

[0041] Furthermore, in order to reduce the downtime frequency of the present invention, a set distance is set between the height detector and the optical fiber sensor 3, and the set distance is used for conveying deformed tobacco rods 4. If a deformed tobacco rod 4 or a tobacco rod 4 that is not well wrapped with transparent paper is found, an early warning is given 17 seconds in advance, and the operator is prompted to remove it while the equipment continues to operate.

[0042] Furthermore, the height detector includes a baffle 5, a rotating shaft 6, a spring 13 and a proximity switch 7. The baffle 5 is rotatably connected to the top of the conveying passage 1 through the rotating shaft 6, and a spring 13 is provided on one side of the upper end of the baffle 5, and the other end of the spring 13 is fixedly connected; the proximity switch 7 is arranged on the other side of the upper end of the baffle 5; when the cigarette rod 4 passes under the baffle 5, when the height exceeds the value of the normal cigarette rod 4, the cigarette rod 4 can drive the baffle 5 to rotate around the rotating shaft 6, so that the upper end of the rotating shaft 6 is away from the proximity switch 7, the controller issues an alarm, and the conveying passage 1 stops running. When the high-level signal output by the proximity switch 7 at the rear of the baffle 5 turns to a low level, it means that the bottom of the baffle 5 is touched, causing the baffle 5 to rotate counterclockwise around the rotating shaft 6, and out of the detection range of the proximity switch 7, triggering the shutdown program of the controller, and after the cigarette rod 4 touching the baffle 5 is taken out of the conveying passage 1, the baffle 5 is restored to a vertical state under the action of the spring 13, and the output of the proximity switch 7 turns from a low level to a high level, and the buzzer of the controller stops alarming.

[0043] Furthermore, the initial state of the baffle 5 is a vertical state, and when the cigarette rod 4 does not interfere with the baffle 5, the other side of the upper end of the baffle 5 is located within the detection range of the proximity switch 7. To avoid the baffle 5 from tilting under the continuous action of the spring 13, when the cigarette rod 4 passes through the baffle 5, the specific height of the cigarette rod 4 cannot be effectively detected.

[0044] Furthermore, if Figure 2As shown, the height detector further includes a housing 12 and a positioning rod. The housing 12 is fixed to one side of the upper end of the baffle 5, and a threaded cavity is provided inside it. The positioning rod is threadedly connected to the housing 12. One end of the spring 13 extends into the threaded cavity and abuts against the positioning rod. By rotating the positioning rod, the resistance of the spring 13 to the baffle 5 is adjusted, thereby controlling the deformation of the baffle 5 and the alarm response speed of the controller.

[0045] Furthermore, the positioning rod includes a screwing-in section 14 and a limiting section 15. The diameter of the limiting section 15 is smaller than the inner diameter of the threaded cavity. The spring 13 is sleeved on the limiting section 15. The screwing-in section 14 is threadedly connected to the threaded cavity, and a flat slot or a cross slot is further provided at the end of the screwing-in section 14, which is convenient for adjustment with a flat screwdriver or a cross screwdriver.

[0046] Furthermore, the adhesion detector includes a diffuse reflection fiber optic sensor 10, which is arranged on one side of the inclined section of the conveying channel 1. When the transparent paper on the adjacent cigarette rods 4 is adhered, that is, when the detection time of the diffuse reflection fiber optic sensor 10 is greater than the sliding time of one cigarette rod 4, the controller issues an alarm. The function of the inclined section has been mentioned above. When there is no adhesion between adjacent cigarette rods 4, the inclined section can ensure that the cigarette rods 4 slide independently along the inclined section, and there must be a gap between adjacent cigarette rods 4, so that the diffuse reflection fiber optic sensor 10 can detect the specific number of cigarette rods 4 according to its light sensing function. When the high-level duration of the diffuse reflection fiber optic sensor 10 is greater than the time for 1.3 cigarettes to pass, that is, there is adhesion between adjacent cigarette rods 4, the buzzer is triggered to alarm.

[0047] Furthermore, the number of cigarette rods 4 lifted by the cigarette rod lifter 11 each time is one. The path between the diffuse reflection fiber optic sensor 10 and the cigarette rod lifter 11 is greater than the sum of the lengths of four cigarette rods 4 and less than the sum of the lengths of five cigarette rods 4. When the diffuse reflection fiber optic sensor 10 continuously detects the cigarette rods 4, the conveying channel 1 stops running. If manual reset is not performed, the cigarette rods 4 are arranged in sequence from the cigarette rod lifter 11 to the cigarette rod beautifier 8. When the high-level duration of the diffuse reflection fiber optic sensor 10 exceeds the time for five cigarettes to pass, that is, when the cigarette rods 4 are arranged in sequence from the entrance of the cigarette rod lifter 11 to the exit of the beautifier at five workstations, the control device stops the machine and the buzzer alarms. The YB95 packaging machine stops until the high-level signal turns into a low-level signal and the buzzer stops alarming, and the YB95 packaging machine can be reset to continue running. This can control the frequency of equipment shutdown due to the appearance or mutual adhesion of cigarette rods 4 to the greatest extent, and at the same time avoid the rigid impact on the equipment and reduce the material consumption and output of the unit.
