Description

Technical Field

[0001] The present invention relates to the technical field of cigarette packaging, and in particular to a system and method for detecting the folding and forming of aluminum foil edges. Background Art

[0002] The quality of the folding of the aluminum foil edges directly affects the next step in the packaging process. If the length difference between the two sides of the aluminum foil is large, it is easy to damage the cigarettes. When the packaging machine runs at high speed, it is also easy to cause problems such as uneven arrangement of cigarettes and cigarettes being thrown out. If the folding angles on both sides of the aluminum foil do not meet the process, it is easy to cause incomplete packaging, and in serious cases, it may cause damage to the equipment.

[0003] Currently, the ZB48 packaging machine uses a fiber optic sensor for aluminum foil edge detection. This sensor, comprised of an amplifier and a slotted photoelectric sensor, operates in a light-on mode. It detects the presence of the foil cigarette edge on the cigarette track. Phase detection is then performed. If the foil cigarette edge is detected missing during this phase interval, it is rejected at the entrance to the first drying wheel. This fiber optic sensor, combined with phase detection, can only detect a single point or line on the foil edge. It cannot detect additional issues such as misaligned corners, tilted edges, and foil tears, presenting a potential quality risk.

[0051] like Figure 1 As shown, the aluminum foil edge folding and forming detection system provided in this embodiment includes:

[0052] A sensor detection head 1, a sensor amplifier assembly 2, a data processing controller 3, and an encoder 4. One end of the sensor amplifier assembly 2 is connected to the sensor detection head 1, and the other end is connected to the data processing controller 3. The input end of the data processing controller 3 is respectively connected to the sensor amplifier assembly 2 and the encoder 4. The output end of the data processing controller 3 is connected to the packaging machine, wherein:

[0053] The sensor detection head 1 is used to detect the light signal of the edge of the aluminum foil along the axis direction, and send the light signal to the sensor amplifier component 2;

[0054] The sensor amplifier assembly 2 is used to receive the light-sensing signal, adjust the light-sensing recognition degree according to the light-sensing signal, convert the light-sensing signal into an electrical signal based on the adjusted light-sensing recognition degree, and send the electrical signal to the data processing controller 3;

[0055] The encoder 4 is used to detect the phase information of the aluminum foil during the rotation and folding process, and send the phase information to the data processing controller 3;

[0056] The data processing controller 3 is used to convert the electrical signal of the aluminum foil edge sent by the sensor amplifier component 2 into a digital signal, and obtain the aluminum foil edge contour information based on the digital signal and the phase information sent by the encoder 4, and send the aluminum foil edge contour information to the packaging machine;

[0057] The packaging machine is used to remove unqualified aluminum foil according to the edge contour information of the aluminum foil.

[0058] The output of the data processing controller 3 is connected to the signal input interface of the packaging machine. The aluminum foil paper continuously moves forward during folding, and each position of its movement has a corresponding phase. The phase is detected by the encoder 4. The phase range of a piece of aluminum foil paper is between 0° and 359°.

[0059] In some embodiments of the present invention, the data processing controller 3 may be, for example, a single chip microcomputer and its peripheral conversion circuit, an IPC small industrial computer, etc. It should be noted that the present invention does not specifically limit the type and model of the data processing controller 3 .

[0060] Furthermore, the sensor detection head 1 includes multiple groups of opposing beam optical fibers, such as opposing focused infrared optical fibers. Each group of opposing beam optical fibers includes a transmitting end and a receiving end that are oppositely disposed. The transmitting ends and receiving ends of adjacent opposing beam optical fibers are staggered to reduce mutual interference. It should be noted that the present invention does not impose any specific limitations on the type or distribution of the opposing beam optical fibers.

[0061] Furthermore, if Figure 2 As shown, the sensor detection head 1 is in a side U-shaped structure, and the aluminum foil horizontally passes through the U-shaped notch of the sensor detection head 1 during the rotation and folding process.

[0062] Furthermore, the sensor amplifier assembly 2 includes a sensor amplifier connected to each set of the opposing optical fibers, each of which is configured to adjust the light sensitivity recognition level based on the light sensing signal detected by the corresponding opposing optical fiber. Thus, each set of opposing optical fibers can independently adjust its trigger value through its corresponding sensor amplifier.

[0063] Furthermore, the data processing controller 3 is specifically used to:

[0064] Convert the electrical signal of the aluminum foil edge sent by the sensor amplifier component 2 into a digital signal;

[0065] Obtaining detection width information of the aluminum foil along the axis direction according to the digital signal;

[0066] According to the phase information sent by the encoder 4, the detection length information of the aluminum foil along the radial direction is obtained;

[0067] Obtaining a detection width-detection length curve of the aluminum foil according to the detection width information and the detection length information;

[0068] Obtaining the detection area of ​​the aluminum foil according to the detection width-detection length curve;

[0069] The detected width information, and / or the detected length information, and / or the detected area are compared with the corresponding standard detected width information, and / or the standard detected length information, and / or the standard detected area to obtain a comparison result. Therefore, the data processing controller 3 can process the digital signal of the aluminum foil edge along the axial direction into the projected area of ​​the aluminum foil. When the aluminum foil edge passes through the sensor detection head 1 of the present invention, the detected area of ​​the aluminum foil edge is scanned into the data processing controller 3. The data processing controller 3 compares and outputs a comparison signal to the main unit of the packaging machine 5 to determine whether to reject the aluminum foil.

[0070] Furthermore, the data processing controller 3 includes a settings module for configuring a number of detection items and corresponding detection ranges. Specifically, the detection items include detecting at least one of: whether the aluminum foil edge is tilted, whether the width and length of the aluminum foil edge are within a preset range, whether the aluminum foil edge has cracks or holes, and whether the angle of the aluminum foil edge is within a preset range. This allows for diverse detection requirements for aluminum foil edges, improving product quality.

[0071] At work, such as Figure 3 As shown, Figure 2 After the sensor detection head 1 collects the light source signal, it is converted into an electrical signal by the sensor amplifier component 2. The received electrical signal is converted into a digital image signal by the data processing controller 3. The data processing controller 3 receives the phase signal of the encoder 4. Figure 3 The figure shows the information obtained by combining the digital image signal with the phase signal of the encoder 4. The horizontal axis represents the detection length, which is obtained by the phase detected by the encoder 4; the vertical axis represents the detection width, which is obtained by the light signal of the aluminum foil edge along the axis direction collected by the sensor detection head 1. The projected area of ​​the solid line in the middle on the horizontal axis represents the detection area of ​​the aluminum foil. Figure 3 The upper and lower dashed lines represent the allowable offsets set by the settings module of the data processing controller 3. The positional relationship between the left and right ends of the curve and the horizontal axis can be used to determine whether the edge of the aluminum foil is tilted. The horizontal and vertical coordinates of the curve can be used to determine whether the width and length of the aluminum foil edge are within a preset range. The continuity of the left and right ends of the curve can be used to determine whether the edge of the aluminum foil is torn or has a hole. The slope of the curve at the left and right ends can be used to determine whether the angle of the aluminum foil edge is within a preset range.

[0072] The aluminum foil edge folding and forming detection system provided by the embodiment of the present invention uses a sensor detection head to detect the light signal of the aluminum foil edge along the axial direction; uses a sensor amplifier component to adjust the light recognition degree according to the light signal, and converts the light signal into an electrical signal; uses an encoder to detect the phase information of the aluminum foil during the rotational folding process; uses a data processing controller to convert the electrical signal of the aluminum foil edge into a digital signal, and obtains the aluminum foil edge contour information based on the digital signal and the phase information, so that the packaging machine can reject unqualified aluminum foil according to the aluminum foil edge contour information, can realize the surface detection of the aluminum foil edge, can check for defects such as corner deviation, edge tilt, and aluminum foil tear, and improve the edge folding and forming quality of the aluminum foil.

[0075] Specifically, the sensor detection head 1 detects the optical signal along the axis of the aluminum foil edge. The sensor detection head 1 includes multiple groups of opposing optical fibers, such as opposing focused infrared optical fibers. Each group of opposing optical fibers includes a transmitting end and a receiving end that are oppositely disposed. The transmitting ends and receiving ends of the opposing optical fibers of the adjacent groups are staggered to reduce mutual interference. It should be noted that the present invention does not specifically limit the type and distribution of the opposing optical fibers.

[0076] like Figure 2 As shown, the sensor detection head 1 is in a side U-shaped structure, and the aluminum foil horizontally passes through the U-shaped notch of the sensor detection head 1 during the rotation and folding process.

[0077] Step S2: adjusting the light sensitivity recognition according to the light sensitivity signal, and converting the light sensitivity signal into an electrical signal based on the adjusted light sensitivity recognition.

[0078] Specifically, the light sensing signal is received by the sensor amplifier component 2 , the light sensing recognition degree is adjusted according to the light sensing signal, and the light sensing signal is converted into an electrical signal based on the adjusted light sensing recognition degree.

[0079] Furthermore, the sensor amplifier assembly 2 includes a sensor amplifier connected to each set of the opposing optical fibers, each of which is configured to adjust the light sensitivity recognition level based on the light sensing signal detected by the corresponding opposing optical fiber. Thus, each set of opposing optical fibers can independently adjust its trigger value through its corresponding sensor amplifier.

[0080] Step S3: detecting phase information of the aluminum foil during the rotation and folding process.

[0081] Specifically, the phase information of the aluminum foil during the rotation and folding process is detected by encoder 4. The aluminum foil continuously moves forward during folding, and each position of its movement has a corresponding phase. The phase detected by encoder 4 is between 0° and 359°.

[0082] Step S4: converting the electrical signal of the edge of the aluminum foil into a digital signal, and obtaining the edge contour information of the aluminum foil according to the digital signal and the phase information.

[0083] The data processing controller 3 converts the electrical signal of the aluminum foil edge sent by the sensor amplifier assembly 2 into a digital signal, and obtains the aluminum foil edge contour information based on the digital signal and the phase information sent by the encoder 4. The data processing controller 3 can be, for example, a single-chip microcomputer and its peripheral conversion circuit, an IPC small industrial computer, etc. In one embodiment of the aluminum foil edge folding and forming detection method of the present invention, step S4 can specifically include:

[0084] Step S41: converting the electrical signal at the edge of the aluminum foil into a digital signal.

[0085] Step S42: Obtain detection width information of the aluminum foil along the axis direction according to the digital signal.

[0087] Step S44: Obtain a detection width-detection length curve of the aluminum foil according to the detection width information and the detection length information.

[0088] Step S45: Obtain the detection area of ​​the aluminum foil according to the detection width-detection length curve.

[0089] Step S46: Compare the detection width information, and / or the detection length information, and / or the detection area with the corresponding standard detection width information, and / or standard detection length information, and / or standard detection area to obtain a comparison result.

[0090] Step S5: The packaging machine removes unqualified aluminum foil according to the edge contour information of the aluminum foil.

[0091] The embodiment of the present invention provides an aluminum foil edge folding and forming detection method, which detects a light-sensing signal of the aluminum foil edge along the axial direction; adjusts the light-sensing recognition degree according to the light-sensing signal, and converts the light-sensing signal into an electrical signal; detects the phase information of the aluminum foil during the rotational folding process; converts the electrical signal of the aluminum foil edge into a digital signal, and obtains the edge contour information of the aluminum foil based on the digital signal and the phase information, so that the packaging machine can reject unqualified aluminum foil according to the edge contour information of the aluminum foil, and can realize surface detection of the aluminum foil edge, can check defects such as folding angle deviation, edge tilt, and aluminum foil tear, and improve the edge folding and forming quality of the aluminum foil.
