Description

Technical Field

[0001] The present invention relates to the field of tape processing, and particularly to a tape transmission device for color mark recognition. Background Art

[0002] Elastic bands are widely used in waistbands, cuffs, etc. When applied to waistbands, they give the waistband a tightening force to prevent the waistband from slipping and the pants from falling off. In the application and processing of elastic bands, a roll of elastic band from an upstream manufacturer is obtained, and then cut into a section of elastic band. In the subsequent process, the two ends of this section of elastic band are sewn into a loop and then sewn to the waistband.

[0003] With the continuous improvement of the requirements of life and production, some manufacturers require that at least one complete LOGO character or other character be attached to the cut section of the elastic band. After this section of elastic band is sewn to the corresponding object, the object can display at least one complete LOGO. Common such objects include sports pants, underwear, etc. in daily life.

[0004] To cut a section of tape, a transmission device and a guillotine are required. The guillotine only cuts the tape. In order to cut a section of tape containing at least one complete LOGO, determining the cutting position of the tape and enabling this cutting position to be transmitted to the guillotine is the main technical point. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides a tape transmission device for color mark recognition, which can determine the cutting position on the tape, facilitating the subsequent cutting of a section of tape containing at least one complete LOGO.

[0006] The present invention also provides a tape cutting system having the above tape transmission device.

[0007] A tape transmission device for color mark recognition according to an embodiment of the first aspect of the present invention includes a frame, a control device, rollers, a first color mark detection component, and a first tape pulling device. The rollers, the first color mark detection component, and the first tape pulling device are all arranged on the frame. The circumferential wall of the roller abuts against the tape, and its rotating shaft is drivingly connected to an encoder. The encoder is electrically connected to the control device to send the detected tape length signal to the control device. The first color mark detection component is used to detect the marking points on the tape, and there is a predetermined distance between the first color mark detection component and the roller. The first tape pulling device can drive the tape to be transmitted so that the tape passes through the roller and the first color mark detection component, and the control device sends a start-stop signal to the first tape pulling device according to the tape length signal.

[0008] A tape transmission device for color mark recognition according to an embodiment of the present invention has at least the following beneficial effects: During tape transmission, the encoder constantly detects the length of the tape, approximately marking length coordinates on the tape. Moreover, the roller and the first color mark detection component have a predetermined length (set length). Therefore, the coordinates of the detection point corresponding to the first color mark detection component can be determined. When the LOGO mark appears below the first color mark detection component and the mark point corresponds to the length coordinate, based on the coordinate point of the mark point and according to the set distance from the mark point to the cutting point designed by the process, the length coordinate of the cutting point is determined.

[0009] According to some embodiments of the present invention, an adjustment mechanism for installing the first color mark detection component is further provided on the frame. The first color mark detection component can change its installation position along the tape transmission direction on the adjustment mechanism, and the predetermined distance can be adjusted. During the actual processing of cutting the tape, different objects (such as clothes and trousers) require tape segments of different lengths. Correspondingly, the mark points and the front cutting points (the front ends of the tape segments) on the tape segments need to be of different lengths. Correspondingly, the first color mark detection component needs to be able to adjust its position along the tape transmission direction (away from or close to the tape cutting device).

[0010] According to some embodiments of the present invention, the adjustment mechanism includes an adjustment slot, a locking block, and a locking screw. The locking block is slidably connected in the adjustment slot, and the locking screw connects the locking block and the first color mark detection component, enabling the locking block and the first color mark detection component to clamp the adjustment slot. By using the adjustment slot, the locking block, and the locking screw, loosening the locking screw slightly can make the locking block and the first color mark detection component not clamp the adjustment slot. The locking block and the first color mark detection component can slide along the tape transmission direction, and the first color mark detection component will not fall off.

[0011] According to some embodiments of the present invention, a scale is further provided on the frame. The scale markings are used to correspond to the first color mark detection component; when the first color mark detection component adjusts its position along the tape transmission direction, it can correspond to different scale markings on the scale. During the sliding process of the first color mark detection component along the tape transmission direction, the working position of the first color mark detection component can be clearly and directly determined.

[0012] According to some embodiments of the present invention, a transmission table is further provided on the frame. Both the roller and the first color mark detection component are arranged above the transmission table. The peripheral wall of the roller abuts against the tape on the transmission table, and the first color mark detection component identifies the tape on the transmission table. The tape is flatly transmitted on the transmission table, which can drive the roller to rotate smoothly and the encoder to read the corresponding tape length value. The first color mark detection component can also better identify the marks on the tape.

[0013] According to some embodiments of the present invention, it further includes a scribing device, which can mark the tape. Marks can be scribed at positions such as the truncation position of the tape.

[0014] According to some embodiments of the present invention, it further includes a tape printing device. The tape printing device and the first color mark detection component are arranged in sequence along the transmission direction of the tape. The tape printing device is used to print marks on the tape, and the first color mark detection component can detect the marks printed by the tape printing device.

[0015] A tape cutting system according to an embodiment of the second aspect of the present invention includes the tape transmission device with color mark recognition described above, and further includes a tape cutting device. There is a predetermined distance between the tape cutting device and the first color mark detection component. The first tape pulling device can drive the tape to transmit, so that the tape passes through the roller, the first color mark detection component, and the tape cutting device.

[0016] A tape cutting system according to an embodiment of the present invention has at least the following beneficial effects: During the tape transmission, the encoder constantly detects the length of the tape, approximately marking length coordinates on the tape. And there is a predetermined length (set length) between the roller and the first color mark detection component. Therefore, the coordinates of the detection point corresponding to the first color mark detection component can be determined; The LOGO mark appears below the first color mark detection component, and the length coordinate corresponding to this mark point is obtained. Based on the coordinate point of the mark point and the set distance from the mark point to the truncation point designed according to the process, the length coordinate of the truncation point is determined; The tape continues to transmit, and the encoder follows the position of the truncation point during transmission. When the truncation point reaches the tape cutting device, the first tape pulling device pauses, and the tape is cut.

[0017] A tape cutting method includes the following steps:

[0018] Obtain a tape roll as the raw material and determine the length L of the tape segment to be cut;

[0019] Establish a mark point, and select a local structure on the graphic pattern as the mark point to be recognized by the first color mark detection component;

[0020] Establish the positions of the front and rear truncation points of the tape segment. The distance a between the front truncation point of the tape and the mark point, and the distance b between the rear truncation point of the tape and the mark point is b = L - a;

[0021] Adjust the installation position of the first color mark detection component. Adjust the installation position of the first color mark detection component along the tape transmission direction, so that the predetermined distance between the first color mark detection component and the tape cutting device is greater than a;

[0022] Mark point, the tape continues to transmit, and the last truncation point B determined most recently before NAfter passing through the first color mark detection component (i.e., the post-truncation point of the latest confirmed previous tape segment), the first color mark detection component starts to identify the newly emerging mark points again;

[0023] Determine the latest pre-truncation point and post-truncation point. The first color mark detection component identifies the latest mark point X N+1 , based on the coordinates (χ N+1 , 0) of this latest mark point X N+1 and the pitch a, a N+1 = χ N+1 - a, calculate the possible coordinates of the latest pre-truncation point A N+1 as (a N+1 , 0). When this possible latest pre-truncation point A N+1 lags behind the previous post-truncation point B N , that is, when a N+1 > b N , this truncation point A N+1 is determined as the required latest pre-truncation point and is truly existent, and at the same time determine the coordinates of the corresponding post-truncation point B N+1 . When this possible latest pre-truncation point A N+1 is ahead of the previous post-truncation point B N , that is, when a N+1 < b N , this possible pre-truncation point A N+1 and the post-truncation point B N+1 are determined to be not truly existent, and the tape continues to be transmitted, and the first color mark detection component identifies the next mark point;

[0024] Cut the tape. When the determined truncation points pass through the tape cutting device, the tape transmission pauses, and the tape cutting device cuts the tape. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

Therefore, it should not be construed as a limitation to the present invention.

[0043] If the first and second are described only for the purpose of distinguishing technical features, it should not be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features or implicitly specifying the sequence relationship of the indicated technical features.

[0044] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installation, connection, etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0045] Refer to Figures 1 to 4 , a tape cutting system, including a tape transmission device with color mark recognition, and further including a tape cutting device 700. The tape transmission device with color mark recognition includes a frame, a control device 110, rollers 210, a first color mark detection component 310, and a first tape pulling device 400. The rollers 210, the first color mark detection component 310, and the first tape pulling device 400 are all arranged on the frame; the peripheral wall of the rollers 210 abuts against the tape, and its rotating shaft is drivingly connected to an encoder 220; the encoder 220 is electrically connected to the control device 110 to send the detected tape length signal to the control device 110; the first color mark detection component 310 is used to detect the identification points on the tape, and there is a predetermined distance between the first color mark detection component 310 and the rollers 210; the first tape pulling device 400 can drive the tape to transmit, so that the tape passes through the rollers 210 and the first color mark detection component 310, and the control device 110 sends a start-stop signal to the first tape pulling device 400 according to the tape length signal.

[0046] The control device 110 is mainly composed of a central processing unit, that is, a common industrial control computer plc, or a single-chip microcomputer, or a dsp, etc. The control device 110 is the common brain of a numerical control machine tool. The first color mark detection component 310 can be a camera, a color sensor, etc. The encoder 220 is commonly used for the detection of motors or rotating shafts, and is most commonly used in the field of machining numerical control machine tools; the rotating shaft of the encoder 220 is drivingly connected to the rotating shaft of the motor. When the rotating shaft rotates, the code disk inside the encoder 220 rotates, and the rotating angle of the rotating shaft is read out by means of photoelectric detection. Then, combined with the determined radius of the motor / rotating shaft, it is converted into a linear displacement; similarly, the encoder 220 reads out the rotating angle, and combined with the radius determined by the rollers 210, the linear displacement of the peripheral wall of the rollers 210, that is, the tape length, is calculated.

[0047] Refer toFigure 8 At the beginning, a certain point on the tape is set as the zero coordinate position of the X-axis (the X-axis is the length coordinate axis), and the current value of the encoder 220 is zero. Taking a certain point on the tape as the zero coordinate position of the X-axis, because of the distance setting between the encoder 220 and the roller 210, the coordinate of the point on the tape where the roller 210 abuts at this moment can be determined. Because of the distance setting between the encoder 220 and the tape cutting device 700, the coordinate of the point on the tape corresponding to the tape cutting device 700 at this moment can also be determined.

[0048] Refer to Figures 1 to 4 As shown in the figure, the first tape pulling device 400 can drive the tape to be transmitted, so that the tape passes through the roller 210, the first color mark detection part 310 and the tape cutting device 700. The first tape pulling device 400 includes a slide seat 410, a slide moving power part 420, a tape pulling jaw 430 and a tape clamping power part 440. The tape clamping power part 440 and the tape pulling jaw 430 are both arranged on the slide seat 410. The tape clamping power part 440 is used to drive the tape pulling jaw 430 to open or clamp, and the slide moving power part 420 is used to drive the slide seat 410 to slide along the tape transmission direction. The tape pulling jaw 430 includes a fixed piece 431 and a movable piece 432. The tape clamping power part 440 and the slide moving power part 420 can both be cylinders, hydraulic cylinders, electric cylinders, etc.

[0049] Refer to Figure 1 and Figure 2 As shown in the figure, the tape cutting device 700 includes a fixed blade, a movable blade and a tape cutting power part. The fixed blade is connected to the frame. The movable blade can be hinged to the frame. The tape cutting power part is used to drive the movable blade to make the guillotine bite or open. The tape cutting power part can be a cylinder, a hydraulic cylinder, an electric cylinder, etc.

[0050] A tape cutting method includes the following steps:

[0051] Obtain the tape roll as the raw material and determine the length L of the tape section to be cut.

[0052] Establish a marking point and input a reference pattern. In some production, the purchased bundled tape already has graphic patterns such as LOGO. Select local structures such as corners and spots on the graphic pattern as the marking points to be recognized by the first color mark detection part 310. The first color mark detection part 310 is a CCD camera. Before production, manually transmit the tape or enable the first tape pulling device 400 to transmit the tape, and input the reference pattern of the structure to be recognized by the first color mark detection part 310; in the graphic pattern design of some tapes, when the graphic pattern passes through the first color mark detection part 310, a certain color patch appears only once. The first color mark detection part 310 is a color sensor.

[0053] Determine the positions of the front and rear truncation points of the tape section. The distance a required between the front truncation point of the tape and the identification point, and the distance b between the rear truncation point of the tape and the identification point is b = L - a. This distance a is input into the control device 110 as one of the parameters; the distance b and the length L can both be input into the control device 110, one as a parameter and the other as data for input correctness verification (whether the relational equation is satisfied).

[0054] Adjust the installation position of the first color mark detection component 310. Along the tape transmission direction, adjust the installation position of the first color mark detection component 310 so that the predetermined distance between the first color mark detection component 310 and the tape cutting device 700 is greater than a.

[0055] Find the identification point. The tape continues to be transmitted, and the last truncation point B determined most recently before N After passing through the first color mark detection component 310 (i.e., the rear truncation point of the most recently confirmed previous tape section), the first color mark detection component 310 starts to identify the newly emerging identification point again.

[0056] Determine the latest front and rear truncation points. The first color mark detection component 310 identifies the latest identification point X N+1 , based on this latest identification point X N+1 's coordinates (χ N+1 , 0) and the distance a, a N+1 = χ N+1 - a, calculate the possible coordinates of the latest front truncation point A N+1 (a N+1 , 0). When this possible latest front truncation point A N+1 lags behind the previous rear truncation point B N , that is, when a N+1 > b N , this truncation point A N+1 is determined as the required latest front truncation point and is the one that truly exists. At the same time, determine the coordinates of the corresponding rear truncation point B N+1 . When this possible latest front truncation point A N+1 is ahead of the previous rear truncation point B N , that is, when a N+1 < b N , this possible front truncation point A N+1 and the rear truncation point B N+1 are determined to not truly exist. The tape continues to be transmitted, and the first color mark detection component 310 identifies the next identification point, and re-consider the possible front and rear truncation points for the next identification point. Refer to Figure 8 's schematic, a N+1 is less than b N , A N+1 is ahead of the previously determined latest rear truncation point B N , identification point XN+1 The corresponding possible truncation points A N+1 and B N+1 do not actually exist and are not used as points for actually truncating the tape; a N+2 is greater than b N , and A N+2 lags behind the determined last truncation point B N , and the identification point X N+2 The corresponding possible truncation points A N+2 and B N+2 actually exist and need to be used as points for actually truncating the tape. The tape between A N+2 and B N+2 is a section of tape required for the process.

[0057] When truncating the tape, when the determined truncation points (each front truncation point and each rear truncation point) pass through the tape cutting device 700, the tape transmission pauses, and the tape cutting device 700 cuts the tape; the tape between the two truncation points determined by the same identification point is truncated into the required tape (refer to the tape between A Figure 8 and B N+2 in N+2 ), and the tape between the rear truncation point determined by one identification point and the front truncation point determined by the next identification point is waste tape (refer to the tape between B Figure 8 and A N in N+2 ). Refer to the schematic diagram in Figure 8 to mark the correct truncation positions with √.

[0058] According to an embodiment of the present invention, a tape transmission device for color mark recognition has at least the following beneficial effects: During tape transmission, the encoder 220 constantly detects the tape length, approximately marking length coordinates on the tape. Moreover, the roller 210 and the first color mark detection component 310 have a predetermined length (set length). Therefore, the coordinates of the detection points corresponding to the first color mark detection component 310 can be determined; the LOGO mark appears below the first color mark detection component 310, and the identification point corresponds to the length coordinate. Based on the coordinate points of the identification point and according to the set distance from the identification point to the truncation point designed by the process, the length coordinates of the truncation point are determined.

[0059] A tape cutting system according to an embodiment of the present invention has at least the following beneficial effects: After determining the length coordinate of the cutting point, the tape continues to be transported. The encoder 220 follows the position of the cutting point during transportation. When the cutting point reaches the tape cutting device 700, the first tape pulling device 400 pauses, and the tape is cut. During the transportation of the tape, the encoder 220 continuously detects the length of the tape, approximately marking length coordinates on the tape. Moreover, the roller 210 and the first color mark detection component 310 have a predetermined length (set length). Therefore, the coordinate of the detection point corresponding to the first color mark detection component 310 can be determined; when the LOGO mark appears below the first color mark detection component 310 and the coordinate of this mark point corresponds to the length coordinate, based on the coordinate point of the mark point and according to the set distance from the mark point to the cutting point designed by the process, the length coordinate of the cutting point is determined; the tape continues to be transported, the encoder 220 follows the position of the cutting point during transportation. When the cutting point reaches the tape cutting device 700, the first tape pulling device 400 pauses, and the tape is cut.

[0060] Referring to Figure 1 and Figure 2 , a rubber band machine, a tape processing device, etc., further includes a sewing unit 800 and a clamping and flipping device. After the tape is cut, its head and tail ends are flipped, the head and tail ends are overlapped, and the tape is clamped and sent into the sewing unit 800, and the head and tail ends are sewn together.

[0061] In some embodiments of the present invention, a position adjustment mechanism 320 for installing the first color mark detection component 310 is further provided on the frame. That is, the first color mark detection component 310 is connected to the frame through the position adjustment mechanism 320, and the first color mark detection component 310 can change its installation position along the tape transportation direction on the position adjustment mechanism 320, and the predetermined distance can be adjusted. In the actual processing of cutting the tape, different objects (such as clothes and trousers) require tape segments of different lengths. Correspondingly, the mark points on this tape segment and the front cutting point (the front end of this tape segment) need to be of different lengths. Correspondingly, the first color mark detection component 310 needs to be able to adjust its position along the tape transportation direction (away from or close to the tape cutting device 700).

[0062] The position adjustment mechanism 320 can be: The position adjustment mechanism 320 includes a position adjustment bolt and a guiding structure. The first color mark detection component 310 is connected to the guiding structure. The guiding structure can be a guide rail, a guide groove, a guide rod, etc. The axial direction of the position adjustment bolt is the tape transportation direction. The position adjustment bolt is threadedly connected to the frame, and a part of the position adjustment bolt passes through the first color mark detection component 310. The part of the position adjustment bolt passing through the first color mark detection component 310 is a rotating ball or a rotor.

[0063] Referring to Figure 5, in some embodiments of the present invention, the position adjustment mechanism 320 includes a position adjustment groove 321, a locking block 322 and a locking screw 323. The locking block 322 is slidably connected in the position adjustment groove 321. The locking screw 323 connects the locking block 322 and the first color mark detection piece 310, and can make the locking block 322 and the first color mark detection piece 310 buckle the position adjustment groove 321. By using the position adjustment groove 321, the locking block 322 and the locking screw 323, loosening the locking screw 323 slightly can make the locking block 322 and the first color mark detection piece 310 not clamp the position adjustment groove 321. The locking block 322 and the first color mark detection piece 310 can slide along the conveying direction of the tape, and the first color mark detection piece 310 will not fall off.

[0064] The locking screw 323 connects the locking block 322 and the first color mark detection piece 310. In some embodiments, refer to Figure 1 , Figure 2 and Figure 5 , the first color mark detection piece 310 is connected to a mounting plate, and the locking screw 323 connects the locking block 322 and the mounting plate.

[0065] Refer to Figure 1 , Figure 3 and Figure 4 , in some embodiments of the present invention, a scale 330 is further provided on the frame. The scale of the scale 330 is used to correspond to the first color mark detection piece 310; when the first color mark detection piece 310 is adjusted along the conveying direction of the tape, it can correspond to different scales on the scale 330. During the process of the first color mark detection piece 310 sliding along the conveying direction of the tape, the working position of the first color mark detection piece 310 can be quickly and straightforwardly determined.

[0066] During the tape conveyance, a certain section of the tape may be suspended. The peripheral wall of the roller 210 can abut against this section of the tape, and the tape conveys and rubs the roller 210; the first color mark detection piece 310 can also be arranged above this section of the tape. In some embodiments of the present invention, a conveying table 120 is further provided on the frame. Both the roller 210 and the first color mark detection piece 310 are arranged above the conveying table 120. The peripheral wall of the roller 210 abuts against the tape on the conveying table 120, and the first color mark detection piece 310 identifies the tape on the conveying table 120. The tape conveys flatly on the conveying table 120, which can drive the roller 210 to rotate smoothly and the encoder 220 reads out the corresponding tape length value, and the first color mark detection piece 310 can also better identify the marks on the tape.

[0067] Refer to Figure 1 and Figure 2 , in some embodiments of the present invention, a scribing device 500 is further included. The scribing device 500 can make marks on the tape. Marks can be made at positions such as the truncation position of the tape.

[0068] The scribing device 500 may be: The scribing device 500 includes a paintbrush 510 and a biaxial displacement mechanism. The paintbrush 510 is connected to the frame through the biaxial displacement mechanism. The biaxial displacement mechanism is used to drive the paintbrush 510 up and down and drive the paintbrush 510 to move in another direction, and this other direction is perpendicular to the direction of the tape transmission.

[0069] Referring to Figures 1 to 3 、 Figure 6 , the scribing device 500 may also be: The scribing assembly includes a paintbrush 510, a slider 520, a guide block 530, a first elastic member 540, and a scribing power member 550; the paintbrush 510 passes through the slider 520, and the scribing power member 550 is used to drive the slider 520 to slide in the front-rear direction. The lower end of the guide block 530 is provided with a concave-convex structure, and the first elastic member 540 is used to drive the paintbrush 510 to abut upward against the concave-convex structure. Combining the first elastic member 540, the concave-convex structure and its specific setting orientation, only one power for front-rear sliding is required to realize the actions of the front-rear sliding and up-down sliding of the paintbrush 510. The scribing power member 550 may be a cylinder; it may also be a structure combined with a motor and a screw-nut pair.

[0070] Referring to Figure 4 , in some embodiments of the present invention, there is also an ink-ribbon printing device 600. The ink-ribbon printing device 600 and the first color mark detection member 310 are arranged in sequence along the transmission direction of the tape. The ink-ribbon printing device 600 is used to print marks on the tape, and the first color mark detection member 310 can detect the marks printed by the ink-ribbon printing device 600.
