Description

Technical Field

[0001] The utility model relates to the field of cigarette-making equipment, and more specifically, to a device for controlling the overlap width of the transparent paper of a cigarette rod. Background Art

[0002] According to the cigarette product quality inspection and management regulations, if the difference in the overlap width at both ends of the transparent paper of the cigarette rod is ≥ 5.0 mm, 0.5 points will be deducted per cigarette rod. Therefore, during the forming and folding process of the transparent paper of the cigarette rod on the packaging machine, fiber optic sensors are installed at two extreme positions to detect the transparent paper and perform rejection.

[0003] Restricted by the transparent paper transmission mechanism, cutting mechanism, stretching mechanism, folding and forming mechanism, and key quality parameters of the transparent paper, etc., it is necessary for the operator to manually adjust the axial position of the transparent paper roll according to the deviation of the overlap width of the transparent paper of the finished cigarette rod, so as to control the overlap width. However, this control method requires repeated participation of the operator and cannot be automatically adjusted.

[0004] In the FOCKE408 cigarette rod transparent paper packaging machine, fiber optic sensors are installed on both sides of the rotating wheel to reject the over-sized cigarette rods. This kind of detection and rejection may have missed detection due to unreasonable threshold setting values of the fiber optic amplifier, or only rejection without feedback for adjustment.

[0027] Now, various exemplary embodiments of the present utility model will be described in detail with reference to the accompanying drawings. It should be noted that: Unless otherwise specifically stated, the relative arrangements of the components and steps set forth in these embodiments, the numerical expressions and values do not limit the scope of the present utility model.

[0028] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way serves as a limitation to the present utility model and its application or use.

[0029] Techniques, methods, and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment shall be regarded as part of the specification.

[0030] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0031] According to Figures 1 to 3 As shown, the utility model provides a device for controlling the lap width of the transparent paper of a cigarette rod, comprising 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; brackets 11 are provided on both sides of the transparent paper conveying path, and the transmitter 12 and the receiver 13 are respectively arranged at the upper and lower ends of the bracket 11 for detecting the edge position information of the transparent paper and outputting it to the controller.

[0033] The laser edge sensor uses multi-band laser to make the shadow of the transparent paper clearer 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. The first fiber optic sensors 21 are respectively located on both sides of the cigarette rod conveying path to detect the position information of the transparent paper on the cigarette rod conveying 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 conveying path to deviate towards that side.

[0035] When any one of the first fiber optic sensors 21 detects that there is no transparent paper below, that is, the controller receives a high-level signal. If three consecutive signals are high-level signals, the deviation between the edge of the transparent paper in the corresponding section of the controller and the current edge remains unchanged. The controller conveys the electrical signal to the adjustment button on the other side through the relay and adjusts the movement of the transparent paper roll through the servo motor. If the deviation between the edge of the transparent paper in the corresponding section of the controller and the current edge changes by more than 1 mm, the controller does not make an output temporarily.

[0036] Furthermore, the detection component further includes a second fiber optic sensor 22. The second fiber optic sensors 22 are located on both sides of the cigarette rod 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 from conveying the transparent paper.

[0037] The detection component further includes a rejection component, which is located on one side of the cigarette bar 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 component to reject the unqualified cigarette bars on the cigarette bar conveying path.

[0038] When any one of the second fiber optic sensors 22 detects that there is transparent paper below, that is, when the controller receives a high-level signal, the controller transmits the high-level signal to the manual rejection button of the FOCKE408, and uses this rejection function to reject the cigarette bars.

[0039] Furthermore, the detection component further includes a third fiber optic sensor 23, which is located above the cigarette bar conveying path and is electrically connected to the controller. When the third fiber optic sensor 23 detects that the rejection component has rejected the rated number of cigarette bars, the controller drives the rejection component to stop rejecting. The rated number of cigarette bars 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 are unqualified cigarette bars on the cigarette bar conveying path. The unqualified cigarette bars in this part are rejected by the rejection component. To prevent the rejection component from continuously rejecting the cigarette bars, the utility model counts the number of cigarette bars rejected by the rejection component through the third fiber optic sensor 23. When the third fiber optic sensor 23 starts to accumulate and count to 3, it indicates that the three cigarette bars along the output direction of the cigarette bar conveying path starting from the position of the third fiber optic sensor 23 are unqualified cigarette bars. The controller transmits the high-level signal to the manual rejection button of the FOCKE408, and uses this rejection function to reject the cigarette bars.

[0041] Furthermore, it further includes a ranging component 3, which is located on one side of the end of the cigarette bar conveying path and is used to detect the lap width of the cigarette bar after being wrapped with transparent paper.

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

[0043] The industrial camera 32 measures the lap width in the middle of the end face of the cigarette bar by using edge detection and distance measurement algorithms. If both the first fiber optic sensor 21 and the second fiber optic sensor 22 are in a low-level signal, but the lap deviation of the cigarette bar is within 2 mm, 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 strip joint exceeds within 5 mm, it indicates that there is a fault in the first fiber optic sensor 21 and the second fiber optic sensor 22. The controller calls the buzzer for alarm processing to prompt the operator to adjust the threshold values of the two groups of fiber optic sensor amplifiers.

[0045] Furthermore, baffles 33 are provided on both sides of the industrial camera 32. One end of each baffle 33 is fixed to the mounting plate 31 by bolts. The industrial camera 32 is stabilized by the baffles 33 to prevent the industrial camera 32 from shaking during shooting, resulting in a decrease in the clarity of the picture.

[0046] Furthermore, a light source generator 34 is provided between the baffles 33. The light source generator 34 is in a ring structure and sleeved on the end of the industrial camera 32 away from the mounting plate 31. The shooting surface of the industrial camera 32 is made clear enough by the light source generator 34 so that the controller can carefully compare the width of the cigarette strip joint according to the preset picture.

[0047] The utility model uses the end to detect the width of the transparent paper joint of the cigarette strip, automatically feedback-adjusts the joint width, reduces the frequency of operator participation in regulation, and ensures that the joints of the finished products meet the enterprise standards. The laser edge sensor is used to detect the transparent paper conveying path to ensure the stable output of the transparent paper. Then, the first fiber optic sensor 21 and the second fiber optic sensor 22 are used to detect the cigarette strip conveying path to ensure the stable packaging between the transparent paper and the cigarette strip. According to the detection data of the two groups of fiber optic sensors, the controller adjusts the edge distance of the transparent paper conveying to ensure the packaging quality of the cigarette strip.

[0048] Although some specific embodiments of the utility model have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for illustration and not for limiting the scope of the utility model. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the utility model. The scope of the utility model is defined by the appended claims.
