Description

Technical Field

[0001] This invention relates to the field of rewinding machine technology, and more specifically, to an automatic labeling rewinding machine control system. Background Technology

[0002] In the film production process, film cutting and inspection and rewinding rejection are required. During rewinding, the start and end positions of rewinding need to be manually located, and then the rewinding machine needs to be manually operated to perform the rewinding operation. Manual operation is cumbersome and time-consuming, and the accuracy of the start and end positions of rewinding is low, which not only affects the rewinding, but may also affect the efficiency of defect rejection in severe cases.

[0003] Existing technologies, such as Chinese Patent CN116253191A, disclose a rewinding machine control system and a control method for the rewinding machine control system, including: a rewinding machine for performing rewinding operations on a diaphragm; an image acquisition device disposed on the rewinding machine for acquiring images of the diaphragm in the rewinding machine; and an industrial control computer electrically connected to the rewinding machine and the image acquisition device, for determining the start and end positions of the rewinding of the diaphragm based on the diaphragm images, and controlling the rewinding operation of the rewinding machine based on the start and end positions of the rewinding.

[0004] However, during the diaphragm rewinding process of the rewinding machine in this patent, only the state image of the diaphragm is detected to check whether the diaphragm meets the specifications, and the automated labeling technology cannot be realized.

[0005] Existing technologies, such as Chinese Patent CN117775445A, disclose a machine vision labeling system and its control method, labeling equipment, and storage medium. The system includes an execution mechanism, an imaging mechanism, a conveying mechanism, and a labeling mechanism. The imaging mechanism and the labeling mechanism are detachably mounted on the execution mechanism. The imaging mechanism is configured to acquire image information, and the conveying mechanism is configured to convey the object to be labeled. The method includes: acquiring image information of the object to be labeled while the execution mechanism follows the object's movement; acquiring pose information of the labeling area of ​​the object based on the image information; controlling the execution mechanism to dynamically track the object based on the pose information of the execution mechanism, the conveying mechanism, and the labeling area; and controlling the labeling mechanism to label the area when the labeling mechanism is synchronized with the labeling area.

[0006] However, this patented technology can only achieve automatic labeling, but it cannot stop in time when the label specifications are not up to standard or the label position is incorrect, and cannot implement different response strategies according to different problems.

[0007] In view of this, the present invention proposes a rewinding machine control system that can automatically apply labels while detecting whether the labels are qualified and / or whether the labels are correctly applied, and apply different corresponding measures when unqualified or incorrect labels are found, thereby implementing automatic labeling. Summary of the Invention

[0008] In view of this, to solve the above problems, the present invention proposes an automatic labeling and rewinding machine control system, including a central control module, a rewinding module, an encoding module, a guiding module, a labeling module, a CCD module, and an image comparison module. The central control module controls the rewinding operation of the rewinding module based on the start and end positions of the rewinding module. The rewinding module is used to rewind the film. The encoding module quickly calculates each labeling position during the start and end processes of the rewinding module and transmits the signal to the central control module. The central control module transmits the labeling position signal from the encoder to the guiding module and the image comparison module. The guiding module controls the position of the labeling module so that the labels applied by the labeling module... The labeling module, whose position is the same as the labeling position transmitted by the encoder, is used to label the film of the rewinding module and transmits the labeling completion signal to the CCD module. The CCD module is used to take a picture of the labeling position after labeling. After taking the picture, the CCD module immediately uploads the picture to the image comparison module. The image comparison module specifies the labeling position transmitted by the central control module as the preset position, compares the picture transmitted by the CCD module with the preset position, and returns the comparison signal to the central control module to check whether the label is qualified and / or whether the labeling is correct. If it is incorrect, the label is manually replaced and / or the central control module controls the rewinding module to stop rewinding and controls the encoding module to re-determine the labeling position.

[0009] Furthermore, the central control module is electrically connected to the rewinding module, the encoding module, the guiding module, and the image comparison module. The rewinding module is electrically connected to the encoding module. The labeling module is electrically connected to the guiding module and the CCD module. The CCD module is electrically connected to the image comparison module.

[0010] Furthermore, the rewinding module includes a rewinding roller, on which a horizontal groove is formed. The groove extends vertically to the upper and lower bottom surfaces and is parallel to the central axis of the rewinding roller. The central control module uses the groove on the rewinding roller as the start and end points of rewinding.

[0011] Furthermore, the encoding module includes an encoder. After inputting the circumference and height of the rewinding roller, as well as the length and width of the required film, into the encoder, the encoder will quickly calculate each labeling position on the rewinding roller based on the speed of the rewinding roller and the size ratio of the rewinding roller to the required film, and transmit each calculated labeling position to the central control unit.

[0012] Furthermore, the guiding module includes multiple guide rods, and a labeling module is provided on the guide rods. The guide rods control the up-down and / or left-right movement of the labeling module, thereby controlling the labeling position of the labeling module.

[0013] Furthermore, the labeling module is equipped with a CCD module, which is also located on the guide module and moves together with the labeling module. The labeling module includes a labeling machine, and the CCD module includes a CCD camera. Both the labeling machine and the CCD camera are positioned facing the groove of the rewinding roller. The height of the labeling machine and the CCD camera relative to the guide mechanism is fixed, and the labeling position of the labeling machine is the same as the image capture position of the CCD camera.

[0014] Furthermore, the guide module may be equipped with one or more labeling modules and CCD modules. When the encoding module calculates that multiple labeling positions are required on the same horizontal line, the guide module is equipped with corresponding multiple labeling modules and CCD modules, and the position of each labeling module and CCD module is controlled so that multiple labeling modules and CCD modules can simultaneously complete the operation on the same horizontal line.

[0015] Furthermore, each time the CCD module receives a signal that the labeling module has applied a label, it automatically takes a picture of the corresponding position and then uploads the completed picture to the image comparison module, thus completing fully automated shooting and uploading.

[0016] Furthermore, the labels used on the labeling module include number or symbol labels, which are used to calculate the number of films or distinguish the size of films, and the preset specifications of the labels can be set in the central control module.

[0017] Furthermore, the image comparison module is equipped with an alarm device. When the image transmitted by the CCD module does not match the label specifications preset by the central control module, the alarm device is triggered, displaying that the label is unqualified, and transmitting a signal to the central control module. The central control module will then pause signal transmission to each module until the label is manually replaced, at which point it will resume operation.

[0018] The beneficial effects of this invention: This invention proposes an automatic labeling and rewinding machine control system, including a central control module, a rewinding module, an encoding module, a guiding module, a labeling module, a CCD module, and an image comparison module. The central control module controls the rewinding operation of the rewinding module based on the start and end positions of the rewinding module. The rewinding module is used to rewind the film. The encoding module is used to quickly calculate each labeling position during the start and end processes of the rewinding module and transmit the signal to the central control module. The central control module transmits the labeling position signal transmitted by the encoder to the guiding module and the image comparison module. The guiding module controls the position of the labeling module so that the position of the label applied by the labeling module is aligned with the encoder position. The labeling module is used to label the film of the rewinding module and transmits the labeling completion signal to the CCD module. The CCD module is used to take a picture of the labeling position after labeling. After taking the picture, the CCD module immediately uploads the picture to the image comparison module. The image comparison module specifies the labeling position transmitted from the central control module as the preset position, compares the picture transmitted from the CCD module with the preset position, and returns the comparison signal to the central control module to check whether the label is qualified and / or whether the affixing is correct. If it is incorrect, the label is manually replaced and / or the central control module controls the rewinding module to stop rewinding and controls the encoding module to re-determine the labeling position.

Example 1:

[0024] like Figure 1 As shown, an automatic labeling and rewinding machine control system includes a central control module, a rewinding module, an encoding module, a guiding module, a labeling module, a CCD module, and an image comparison module. The central control module controls the rewinding operation of the rewinding module based on its start and end positions. The rewinding module rewinds the film. The encoding module quickly calculates each labeling position during the rewinding process and transmits the signal to the central control module. The central control module transmits the labeling position signal from the encoder to the guiding module and the image comparison module. The guiding module controls the position of the labeling module so that the label position applied by the labeling module matches the labeling position transmitted by the encoder. The labeling module, located at the same position, is used to apply labels to the film of the rewinding module and transmits the labeling completion signal to the CCD module. The CCD module is used to capture an image of the labeling position after labeling. After capturing the image, the CCD module immediately uploads the image to the image comparison module. The image comparison module specifies the labeling position transmitted from the central control module as a preset position, compares the image transmitted from the CCD module with the preset position, and returns the comparison signal to the central control module. This verifies whether the label is qualified and / or whether the labeling is correct. If incorrect, the label is manually replaced and / or the central control module controls the rewinding module to stop rewinding and controls the encoding module to re-determine the labeling position.

The central control module uses the groove on the rewinding roller as the start and end points of the rewinding.

[0027] In some embodiments, the encoding module includes an encoder. After the circumference and height of the rewinding roller, as well as the length and width of the required film, are input into the encoder, the encoder will quickly calculate each labeling position on the rewinding roller according to the speed of the rewinding roller and the size ratio of the rewinding roller to the required film, and transmit each calculated labeling position to the central control unit.

[0028] In some embodiments, the guiding module includes a plurality of guide rods, on which a labeling module is provided. The guide rods control the up-down and / or left-right movement of the labeling module, thereby controlling the labeling position of the labeling module.

The labeling module includes a labeling machine, and the CCD module includes a CCD camera. The labeling machine and the CCD camera are both arranged facing the groove of the rewinding roller. The height of the labeling machine and the CCD camera is fixed with respect to the guide mechanism, and the labeling position of the labeling machine is the same as the image capture position of the CCD camera.

[0030] In some embodiments, the guide module may be provided with one or more labeling modules and CCD modules. When the encoding module calculates that multiple labeling positions are required on the same horizontal line, the guide module is provided with corresponding multiple labeling modules and CCD modules, and the position of each labeling module and CCD module is controlled so that multiple labeling modules and CCD modules can simultaneously complete the operation on the same horizontal line.

[0031] In some embodiments, each time the CCD module receives a signal that the labeling module has applied a label, it automatically takes a picture of the corresponding position and then uploads the completed picture to the image comparison module, thus completing fully automated shooting and uploading.

[0033] In some embodiments, the image comparison module is equipped with an alarm device. When the image transmitted by the CCD module does not match the label specifications preset by the central control module, the alarm device is triggered, indicating that the label is unqualified, and a signal is transmitted to the central control module. The central control module will pause the signal transmission to each module, and will resume operation after the label is manually replaced.
