Description

Technical Field

[0001] This invention relates to the field of cigarette manufacturing equipment, and more specifically, to a device for controlling the width of the overlap of the transparent paper on a cigarette pack. Background Technology

[0002] According to the regulations for the quality inspection and management of cigarette products, a difference in the width of the overlap between the two ends of the transparent paper of a cigarette pack is ≥5.0mm, and 0.5 points are deducted per pack. Therefore, during the forming and folding process of the transparent paper of the cigarette pack, the packaging machine installs fiber optic sensors at two extreme positions to detect and reject the transparent paper.

[0003] Due to limitations imposed by the transparent paper conveying mechanism, cutting mechanism, stretching mechanism, folding and forming mechanism, and key quality parameters of the transparent paper, operators need to manually adjust the axial position of the transparent paper roll based on the deviation of the overlap width of the finished cigarette pack transparent paper, thereby controlling the overlap width. However, this control method requires repeated intervention from the operator and cannot be automatically adjusted.

[0004] Inside the FOCKE408 cigarette packing machine, fiber optic sensors are installed on both sides of the rotating wheel to reject oversized cigarette packs. This detection and rejection method has the problem of missed detections due to unreasonable threshold settings of the fiber optic amplifier, or it may simply reject the cigarette packs without providing feedback for adjustment. Summary of the Invention

[0005] One object of the present invention is to provide a new technical solution for a cigarette pack transparent paper overlap width control device to solve the problems mentioned in the background art.

[0006] According to a first aspect of the present invention, a device for controlling the overlap width of the transparent paper of a cigarette pack is provided, comprising a laser edge sensor, a detection component, and a controller;

[0007] The laser edge sensor includes a transmitter, a receiver, and a bracket; the bracket is provided on both sides of the transparent paper conveying path, and the transmitter and the receiver are respectively located at the upper and lower ends of the bracket, for detecting the edge position information of the transparent paper and outputting it to the controller;

[0008] The detection component includes a first fiber optic sensor, which is located on both sides of the cigarette pack conveying path to detect the position information of the transparent paper on the cigarette pack conveying path and output it to the controller. When the first fiber optic sensor on either side cannot detect the position information of the transparent paper, the controller can adjust the transparent paper conveying path to shift towards that side.

[0009] Optionally, in the cigarette pack transparent paper overlap width control device according to the present invention, the detection component further includes a second optical fiber sensor, the second optical fiber sensor being located on both sides of the cigarette pack conveying path, and the spacing between the second optical fiber sensors being greater than the spacing between the first optical fiber sensors. When the second optical fiber sensor on either side detects the position information of the transparent paper, the controller can stop the transparent paper conveying path and stop conveying the transparent paper.

[0010] Optionally, according to the cigarette pack transparent paper overlap width control device of the present invention, the detection component further includes a rejection component, which is located on one side of the cigarette pack conveying path and electrically connected to the controller. When the second fiber optic sensor detects the position information of the transparent paper, the controller drives the rejection component to reject unqualified cigarette packs on the cigarette pack conveying path.

[0011] Optionally, according to the cigarette pack transparent paper overlap width control device of the present invention, the detection component further includes a third fiber optic sensor, which is located above the cigarette pack conveying path and electrically connected to the controller. When the third fiber optic sensor detects that the rejection component has rejected a rated number of cigarette packs, the controller drives the rejection component to stop rejection.

[0012] Optionally, according to the cigarette pack transparent paper overlap width control device of the present invention, the rated number of cigarette packs rejected by the rejection component is 1-3.

[0013] Optionally, the cigarette pack transparent paper overlap width control device according to the present invention further includes a ranging component, which is located on one side of the end of the cigarette pack conveying path and is used to detect the overlap width of the cigarette pack after wrapping transparent paper.

[0014] Optionally, in the cigarette pack transparent paper overlap width control device according to the present invention, the ranging component includes an industrial camera and a mounting plate. The mounting plate is fixed to one side of the end of the cigarette pack conveying path, and the industrial camera is fixed to the mounting plate by bolts, with the shooting surface of the industrial camera facing the cigarette pack conveying path.

[0015] Optionally, according to the cigarette bar transparent paper overlap width control device of the present invention, baffles are also provided on both sides of the industrial camera, and one end of each baffle is fixed to the mounting plate by bolts.

[0016] Optionally, in the cigarette pack transparent paper overlap width control device according to the present invention, a light source generator is provided between the baffles, and the light source generator is arranged in a ring structure at the end of the industrial camera away from the mounting plate.

[0017] This invention utilizes end-effector detection to measure the overlap width of the cigarette pack's transparent paper, automatically adjusting the overlap width to reduce the frequency of operator intervention and ensure the finished product's overlap meets company standards. A laser edge sensor detects the transparent paper's conveying path, ensuring stable output. Furthermore, first and second fiber optic sensors detect the cigarette pack's conveying path, ensuring stable packaging between the transparent paper and the cigarette pack. Based on the detection data from the two sets of fiber optic sensors, a controller adjusts the edge distance of the transparent paper conveying process, guaranteeing the packaging quality of the cigarette pack.

[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, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

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

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

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

[0031] according to Figures 1 to 3 As shown, the present invention provides a device for controlling the overlap width of the transparent paper of a cigarette pack, including a laser edge sensor, a detection component, and a controller;

[0032] The laser edge sensor includes a transmitter 12, a receiver 13, and a bracket 11. The brackets 11 are provided on both sides of the transparent paper conveying path. The transmitter 12 and the receiver 13 are respectively located at the upper and lower ends of the brackets 11 to detect the edge position information of the transparent paper and output it to the controller.

[0033] The laser edge sensor uses multi-band lasers to make the shadow of the transparent paper more clearly formed on the CCD. With the help of the communication unit, the edge position information is output to the controller using the RS-232C protocol, and the edge position information of the transparent paper is displayed in real time.

[0034] The detection component includes a first fiber optic sensor 21, which is located on both sides of the cigarette packing path to detect the position information of the transparent paper on the cigarette packing path and output it to the controller. When the first fiber optic sensor 21 on either side fails to detect the position information of the transparent paper, the controller can adjust the transparent paper packing path to shift towards that side.

[0035] When any of the first fiber optic sensors 21 detects that there is no transparent paper underneath, that is, the controller receives a high-level signal. If three consecutive signals are high-level, the controller will not change the deviation between the edge of the transparent paper in the corresponding segment and the current edge. The controller will send an electrical signal to the other side of the means adjustment button through the relay, and adjust the movement of the transparent paper roll through the servo motor. If the deviation between the edge of the transparent paper in the corresponding segment and the current edge changes by more than 1mm, the controller will temporarily not output.

[0036] Furthermore, the detection component also includes a second fiber optic sensor 22, which is located on both sides of the cigarette pack conveying path, and the distance between the second fiber optic sensors 22 is greater than the distance between the first fiber optic sensors 21. When the second fiber optic sensor 22 on either side detects the position information of the transparent paper, the controller can stop the transparent paper conveying path and stop conveying the transparent paper.

[0037] The detection assembly also includes a rejection assembly, which is located on one side of the cigarette pack conveying path and is electrically connected to the controller. When the second fiber optic sensor 22 detects the position information of the transparent paper, the controller drives the rejection assembly to reject the unqualified cigarette packs on the cigarette pack conveying path.

[0038] When any of the second fiber optic sensors 22 detects the presence of transparent paper underneath, the controller receives a high-level signal and sends the high-level signal to the manual rejection button on the FOCKE408, using this rejection function to remove the cigarette sticks.

[0039] Furthermore, the detection component also includes a third fiber optic sensor 23, which is located above the cigarette packing path and is electrically connected to the controller. When the third fiber optic sensor 23 detects that the rejection component has rejected a rated number of cigarette packs, the controller drives the rejection component to stop rejecting. The rated number of cigarette packs rejected by the rejection component is 1-3.

[0040] In this embodiment, when the deviation distance of the transparent paper is too large, that is, when the second fiber optic sensor 22 can detect the position information of the transparent paper, it indicates that there is a problem with the cigarettes on the cigarette conveying path being defective. The defective cigarettes are then removed by the rejection component. To prevent the rejection component from continuously rejecting cigarettes, the present invention uses a third fiber optic sensor 23 to count the number of cigarettes rejected by the rejection component. When the third fiber optic sensor 23 starts to accumulate a count of 3, it indicates that three cigarettes along the output direction of the cigarette conveying path from the position of the third fiber optic sensor 23 are defective cigarettes. The controller sends a high-level signal to the FOCKE408 manual rejection button, and the cigarettes are rejected using this rejection function.

[0041] Furthermore, it also includes a ranging component 3, which is located on one side at the end of the cigarette pack conveying path and is used to detect the width of the cigarette pack overlap after wrapping with transparent paper.

[0042] The ranging component 3 includes an industrial camera 32 and a mounting plate 31. The mounting plate 31 is fixed to one side of the end of the cigarette conveying path. The industrial camera 32 is fixed to the mounting plate 31 by bolts, and the shooting surface of the industrial camera 32 is facing the cigarette conveying path.

[0043] The industrial camera 32 uses edge detection and distance measurement algorithms to measure the width of the overlap in the middle of the cigarette strip end face. If both the first fiber optic sensor 21 and the second fiber optic sensor 22 are at a low level signal, but the overlap deviation of the cigarette strip is within 2mm, the controller adjusts the transparent paper roll to move 1 / 3 of the distance in the opposite direction.

[0044] When both the first fiber optic sensor 21 and the second fiber optic sensor 22 are at a low level signal, but the deviation of the cigarette stick overlap exceeds 5mm, it indicates that the first fiber optic sensor 21 and the second fiber optic sensor 22 are faulty. The controller will call the buzzer to sound an alarm and prompt the operator to adjust the threshold of the amplifiers of the two sets of fiber optic sensors.

[0045] Furthermore, baffles 33 are provided on both sides of the industrial camera 32, and one end of each baffle 33 is fixed to the mounting plate 31 with bolts. The baffles 33 stabilize the industrial camera 32 and prevent it from shaking during shooting, which would reduce the clarity of the image.

[0046] Furthermore, a light source generator 34 is provided between the baffles 33. The light source generator 34 is arranged in a ring structure and is fitted around the end of the industrial camera 32 away from the mounting plate 31. The light source generator 34 ensures that the shooting surface of the industrial camera 32 is clear enough so that the controller can carefully compare the width of the smoke strip overlap according to the preset image.

[0047] This invention utilizes end-effector detection to measure the overlap width of the cigarette pack's transparent paper, automatically adjusting the overlap width to reduce the frequency of operator intervention and ensure that the finished product's overlap meets enterprise standards. A laser edge sensor detects the transparent paper's conveying path to ensure stable output, while a first fiber optic sensor 21 and a second fiber optic sensor 22 further detect the cigarette pack's conveying path to ensure stable packaging between the transparent paper and the cigarette pack. Based on the detection data from the two sets of fiber optic sensors, a controller adjusts the edge distance of the transparent paper conveying path to guarantee the packaging quality of the cigarette pack.

[0048] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
