Description

Technical Field

[0001] This invention relates to the field of cigarette production equipment and cigarette production technology, specifically to a control method for a YB518 dual-channel cigarette pack transparent paper width quantitative control system. Background Technology

[0002] In cigarette production and packaging, the transparent wrapping of the cigarette pack is an important component of the packaging machine. For example... Figure 1 The diagram shown illustrates how the existing YB518 model controls the width of the transparent paper on two tracks. Two photoelectric switches, B23.0 and B23.1, are used for detection. Figure 2 Press the edge of the whole transparent paper as shown. Figure 1 The schematic diagram shown controls the width of the transparent paper: when photoelectric switch detector B23.0 does not detect the transparent paper but photoelectric switch detector B23.1 detects the transparent paper, it is in normal condition; otherwise, motor M12 rotates in the forward / reverse direction, and then the actuator brings the transparent paper to the normal state.

[0003] In actual production, because photoelectric detectors cannot quantitatively control the width of the cut transparent paper and industrial production sites are prone to dust accumulation, uneven widths often occur between the two cut transparent sheets. This is especially true after the transparent sheets are spliced ​​together, where the width of the transparent paper on the two tracks is more likely to be uneven. This uneven width of the transparent paper on the two tracks leads to incomplete wrapping of the cigarette packs, seriously affecting the quality of cigarette pack production. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a control method for the YB518 dual-channel cigarette pack transparent paper width quantitative control system. The control method has been redesigned to achieve quantitative control and adjustment of the transparent paper width after cutting. When the width of a single transparent paper sheet on either track does not meet the requirements of the cigarette pack production process after the entire transparent paper is cut, the dual-channel cigarette pack transparent paper width quantitative control system adjusts the position of the entire transparent paper sheet (by controlling the forward / reverse rotation of the motor and controlling the adjustment roller group to move axially along the roller and / or along the axial direction inclined to the roller), ensuring that the transparent paper width on both tracks is balanced (consistent with the standard width). This avoids incomplete wrapping of the cigarette pack due to insufficient transparent paper width, thus guaranteeing the quality of the cigarette pack product.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A control method for a YB518 dual-channel cigarette pack transparent paper width quantification control system, the control system includes an adjusting roller group (2), a cutter (3), an industrial camera (5), a guide roller group (6), a main drive disk (7), a photoelectric switch, an industrial computer, a PLC controller, an original machine controller A12, and a motor M12. Along the conveying direction of the transparent paper, the main drive disk is located upstream of the guide roller group, the adjusting roller group is located downstream of the guide roller group, a transparent paper cutting roller group is located downstream of the adjusting roller group, a transparent paper cutting cutter is located on the upper side of the transparent paper cutting roller group, and an industrial camera is located on the lower side of the transparent paper cutting roller group; after the photoelectric switch senses the sensor, it triggers the industrial camera through the industrial computer, the industrial computer is electrically connected to the photoelectric switch and the PLC controller, and the PLC controller is electrically connected to the original machine control execution unit; the characteristic is that it includes the following process steps: Step S1: The YB518 model is a dual-channel cigarette packaging machine with a relatively slow operating speed. The photoelectric switch is designed to emit two pulses for each station of operation in the dual-channel cigarette packaging machine to increase the sampling frequency of the transparent paper width. Step S2: When the YB518 model is running, the entire sheet of transparent paper is conveyed from left to right according to the original machine conveying method. When the entire sheet of transparent paper is conveyed to the cutter, the cutter cuts the entire sheet of transparent paper into two sheets of transparent paper (4A, 4B). After receiving the high-level signal from the photoelectric switch, the industrial computer triggers the industrial camera to take a picture of the single sheet of transparent paper (4B) on the two-roller assembly of transparent paper cutting. After taking the picture, the industrial camera converts the optical signal into an analog current signal and transmits it to the industrial computer. Step S3: The transparent paper width data obtained by the industrial computer is transmitted to the PLC controller via electrical connection; the PLC controller uses the transparent paper width data transmitted by the industrial computer as the comparison number / measured width in the comparison instruction; it compares whether the measured width is equal to the standard width, and controls the motor to rotate forward / reverse according to the comparison result, and adjusts the displacement of the adjusting roller group so that the transparent paper width on the two tracks of the transparent paper cutting roller group is balanced.

[0006] Furthermore, in step S3: Step S31: When the measured width is equal to the standard width, it indicates that the dual-channel model is operating normally; Step S32: When the measured width is not equal to the standard width, compare whether the measured width is greater than the standard width. Step S33: When the measured width is greater than the standard width, the original machine controller A12 controls the motor M12 to rotate forward and controls the adjusting roller group (2) to move along the axial direction of the roller and / or along the axial direction inclined to the roller; quantitative control adjusts the width of the transparent paper on track one and track two of the transparent paper cutting two roller group so that the transparent paper on the two tracks achieves a balanced width. Step S34: When the measured width is less than the standard width, the original machine controller A12 controls the motor M12 to reverse and controls the adjusting roller group (2) to move along the axial direction of the roller and / or along the axial direction inclined to the roller; quantitative control adjusts the width of the transparent paper on track one and track two of the transparent paper two-roller group so that the transparent paper on the two tracks achieves a balanced width.

[0007] Furthermore, two screws are embedded in the main drive plate of the YB518 model. When the YB518 model is running, the photoelectric switch senses the screws twice for each station it moves, and sends out two pulse signals. The photoelectric switch is of PNP type. When the photoelectric switch senses the screw, it outputs a high-level signal, which is then sent to the industrial computer.

[0008] Furthermore, the industrial computer amplifies and converts the analog current signal of the transparent paper image captured by the industrial camera into digital form, acquires the image, processes it, and obtains the transparent paper width data. According to the requirements of cigarette production process, the width of a single transparent paper cannot exceed the standard width of 1mm; therefore, the industrial computer measures the width of the transparent paper captured by the industrial camera in units of 0.1mm. The transparent paper width data obtained by the industrial computer is transmitted to the PLC controller through an electrical connection.

[0009] Furthermore, during the operation of the YB518 model, the PLC controller compares the received transparent paper width "IN1" signal with the transparent paper's "standard width." The industrial computer transmits the value "N1" to the PLC processor. When the value "N1" transmitted by the industrial computer is not equal to the standard width, the PLC controller outputs a high-level signal to pin 3 of the original controller A12 as an enable signal for A12.0. When there is a high-level enable signal at pin 3 of the original controller A12, meaning the value "IN1" transmitted by the industrial computer is not equal to the standard width, the PLC controller outputs a high-level signal to pin 3 of the original controller A12 as an enable signal for A12.0. "If the width is greater than the standard width, the PLC controller outputs a high level to pin 4 of the original controller A12 as a forward rotation signal for the drive motor M12; otherwise, there is no high level signal at pin 4 of the original controller A12, and the drive motor M12 reverses; when the measured width is not equal to the standard width, the motor M12 is controlled to move forward / reverse, and the adjusting roller group (2) is controlled to move along the axial direction of the roller and / or along the axial direction inclined to the roller, so as to move the entire transparent paper; the width of the transparent paper on track 1 and track 2 of the two roller groups of the transparent paper is adjusted by quantitative control so that the width of the transparent paper on the two tracks is balanced and consistent with the standard width."

[0010] This invention discloses a control method for a YB518 dual-channel cigarette pack transparent paper width quantification control system. The control method has been redesigned to achieve quantitative control and adjustment of the transparent paper width after cutting. When the width of a single transparent paper sheet on either track does not meet the requirements of the cigarette pack production process after the entire transparent paper is cut, the dual-channel cigarette pack transparent paper width quantification control system adjusts the position of the entire transparent paper sheet (by controlling the forward / reverse rotation of the motor and controlling the adjustment roller group to move axially along the roller and / or along the axial direction inclined to the roller), ensuring that the transparent paper width on both tracks is balanced (consistent with the standard width). This avoids incomplete wrapping of the cigarette pack due to insufficient transparent paper width, thus guaranteeing the quality of the cigarette pack product. Attached Figure Description

[0015] like Figure 2-4As shown, a control method for a YB518 dual-channel cigarette pack transparent paper width quantification control system is disclosed. The control system includes an adjusting roller group 2, a cutter 3, an industrial camera 5, a guide roller group 6, a main drive disk 7, a photoelectric switch, an industrial computer, a PLC controller, an original machine controller A12, and a motor M12. Along the conveying direction of the transparent paper 1, the main drive disk 7 is positioned upstream of the guide roller group 6, and the adjusting roller group 2 is positioned downstream of the guide roller group 6. A transparent paper cutting roller group is positioned downstream of the adjusting roller group 2. A transparent paper cutting cutter 3 is positioned above / on the transparent paper cutting roller group, and an industrial camera 5 is positioned below / on the transparent paper cutting roller group. The photoelectric switch senses the sensor and triggers the industrial camera 5 via the industrial computer. The industrial computer is electrically connected to the photoelectric switch and the PLC controller, and the PLC controller is electrically connected to the original machine control execution unit. The system is characterized by the following process steps: Step S1: The YB518 model is a dual-channel cigarette packaging machine with a relatively slow operating speed. The photoelectric switch is designed to emit two pulses for each station of operation in the dual-channel cigarette packaging machine to increase the sampling frequency of the transparent paper width. Step S2: When the YB518 model is running, the whole sheet of transparent paper 1 is conveyed from left to right according to the original conveying method. When the whole sheet of transparent paper is conveyed to the cutter, the cutter 3 cuts the whole sheet of transparent paper into two sheets of transparent paper 4A and 4B. After receiving the high-level signal from the photoelectric switch, the industrial computer triggers the industrial camera 5 to take a picture of the single sheet of transparent paper 4B on the two-roller assembly of transparent paper cutting. After taking the picture, the industrial camera 5 converts the optical signal into an analog current signal and transmits it to the industrial computer. Step S3: The transparent paper width data obtained by the industrial computer is transmitted to the PLC controller via electrical connection; the PLC controller uses the transparent paper width data transmitted by the industrial computer as the comparison number / measured width in the comparison instruction; it compares whether the measured width is equal to the standard width, and controls the motor M12 to rotate forward / reverse according to the comparison result, and adjusts the displacement of the adjusting roller group 2 so that the transparent paper width on the two tracks of the transparent paper cutting roller group is balanced.

[0016] Furthermore, in step S3: Step S31: When the measured width is equal to the standard width, it indicates that the dual-channel model is operating normally; Step S32: When the measured width is not equal to the standard width, compare whether the measured width is greater than the standard width. Step S33: When the measured width is greater than the standard width, the original machine controller A12 controls the motor M12 to rotate forward and controls the adjusting roller group 2 to move along the axial direction of the roller and / or along the axial direction inclined to the roller (one-dimensional movement or two-dimensional movement: to move the entire transparent paper 1); quantitative control adjusts the width of the transparent paper on track one and track two of the two roller groups of the transparent paper to make the width of the transparent paper on the two tracks equal. Step S34: When the measured width is less than the standard width, the original controller A12 controls the motor M12 to reverse and controls the adjusting roller group 2 to move along the axial direction of the roller and / or along the axial direction inclined to the roller (one-dimensional movement or two-dimensional movement: to move the entire transparent paper 1); quantitative control adjusts the width of the transparent paper on track one and track two of the two roller groups of the transparent paper to make the width of the transparent paper on the two tracks equal.

[0017] Two screws are embedded in the main drive plate of the YB518 model. When the YB518 model is running, the photoelectric switch senses the screws twice for each station it moves, and sends out two pulse signals. The photoelectric switch is of PNP type. When the photoelectric switch senses the screws, it outputs a high-level signal, which is then sent to the industrial computer.

[0018] The industrial computer amplifies and converts the analog current signal of the transparent paper image captured by the industrial camera into digital form, acquires the image, processes it, and obtains the transparent paper width data. According to the requirements of cigarette production process, the width of a single transparent paper cannot exceed the standard width of 1mm; therefore, the industrial computer measures the width of the transparent paper captured by the industrial camera in units of 0.1mm. The transparent paper width data obtained by the industrial computer is transmitted to the PLC controller through an electrical connection.

[0019] Furthermore, during the operation of the YB518 model, the PLC controller compares the received transparent paper width "IN1" with the transparent paper's "standard width," as shown in the program control diagram (e.g.). Figure 4 As shown); when the machine is running, Figure 4 When "RUN" is activated, the industrial computer transmits the value "N1" to the PLC processor. When the value "N1" transmitted by the industrial computer is not equal to the standard width, the PLC controller outputs a high-level signal to pin 3 of the original controller A12 as the enable signal for A12.0. If there is a high-level enable signal at pin 3 of the original controller A12, that is, when the value "IN1" transmitted by the industrial computer is not equal to the standard width, and the value "IN1" received by the industrial computer is greater than the standard width, the PLC controller outputs a high-level signal to pin 4 of the original controller A12 as the forward rotation signal for the drive motor M12. Otherwise, there is no high-level signal at pin 4 of the original controller A12, and the drive motor M12 reverses.

[0020] The present invention discloses a control method for a YB518 dual-channel cigarette pack transparent paper width quantification control system. When the measured width is not equal to the standard width, the method controls the forward / reverse rotation of the motor M12 and controls the adjustment roller group 2 to move along the axial direction of the roller and / or along the axial direction inclined to the roller (one-dimensional or two-dimensional movement: to move the entire transparent paper 1). The method quantifies and controls the adjustment of the transparent paper width on track one and track two of the two roller groups to make the transparent paper on the two tracks achieve a width balance (consistent with the standard width).

[0021] The present invention discloses a control method for a YB518 dual-channel cigarette pack transparent paper width quantification control system. This redesigned control method achieves quantified control adjustment of the transparent paper width after cutting. When the width of a single transparent paper sheet on either track fails to meet the cigarette pack production process requirements after the entire transparent paper is cut, the dual-channel cigarette pack transparent paper width quantification control system adjusts the position of the entire transparent paper sheet (by controlling the forward / reverse rotation of motor M12 and controlling the axial movement of adjusting roller group 2 along the roller and / or along the axial movement inclined to the roller), ensuring that the transparent paper width on both tracks is balanced (consistent with the standard width). This avoids incomplete wrapping of the cigarette pack due to insufficient transparent paper width, thus guaranteeing the quality of the cigarette pack product.

[0022] It should be noted that all directional indicators (such as up, down, left, right, front, back, horizontal, vertical, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly. The "connection" can be a direct connection or an indirect connection. The "set", "set in", and "set at" can be a direct setting or an indirect setting.
