Description

Technical Field

[0001] The present application relates to the technical field of label production, and in particular to an automatic detection mechanism for a ribbon box. Background Art

[0002] During the label production process, fully automated label printing is primarily accomplished through label printers. Label printers typically include a print head, print roller, and ribbon cassette. The ribbon cassette contains the ribbon and label tape, and the ribbon cassette is removably installed within the label printer. During label printing, the print head and print roller together clamp the ribbon and label tape, transferring the printed information on the ribbon to the label tape. This allows the desired information to be printed on the label tape, creating the desired label. After printing is complete, the used ribbon is directly reeled into the ribbon cassette, and the printed label tape is transported outward through the cooperation of the print head and print roller, allowing the label tape with printed information to be discharged from the outlet of the label printer.

[0003] Currently, label inspection focuses on the printing quality of the information on the label. The printing quality of the label is mainly related to the ribbon in the ribbon cassette. Therefore, the most important thing for label inspection is to detect whether the ribbon in the corresponding ribbon cassette is broken or falling off. To facilitate the inspection of ribbon cassettes, some existing ribbon cassettes are designed to be fully transparent or semi-transparent, so that the condition of the ribbon inside the cassette can be observed. Then, the condition of the ribbon inside the cassette can be inspected manually or by visual inspection systems to determine whether the cassette is qualified.

[0004] The above detection method detects whether the ribbon is broken when the ribbon cassette is not in use. However, when the ribbon cassette is actually used, the label printer will pull the ribbon, which will cause the ribbon to deform under stress. This may cause the ribbon cassette to pass the factory inspection, but when the ribbon cassette is actually used in the label printer, the ribbon may break due to the stress, and the ribbon cassette will fail to pass the test during actual use, resulting in inaccurate detection results. Summary of the Invention

[0005] The present application provides an automatic detection mechanism for a ribbon cassette, the purpose of which is to detect whether the ribbon in the ribbon cassette is broken under the condition of simulating the use of the ribbon cassette, thereby improving the accuracy of the ribbon cassette detection result.

[0006] The present application provides an automatic detection mechanism for a ribbon cartridge that adopts the following technical solutions: A ribbon cassette automatic detection mechanism comprises a mounting plate, on which a mounting assembly for mounting a ribbon cassette is provided; an analog mechanism comprises a drive shaft, one end of which is rotatably connected to the mounting plate, the drive shaft being coaxially connected to a rotating drive member, the drive shaft being used to drive the ribbon conveyance in the ribbon cassette; a ribbon detection mechanism comprises a driven shaft, the driven shaft is spaced apart and parallel to the drive shaft, one end of the driven shaft is rotatably connected to the mounting plate, the driven shaft being used to abut the ribbon and assist in conveying the ribbon; a rotation detection assembly is connected to the mounting plate, the rotation detection assembly being used to detect the rotation of the driven shaft.

[0007] By adopting the above technical solution, the mounting plate can be installed on the mounting plate through the setting of the mounting assembly. The simulation mechanism is provided by the setting of the drive shaft. After the ribbon cassette is installed on the mounting plate, the rotating driving member drives the drive shaft to rotate to realize the ribbon conveying. This can simulate the force applied to the ribbon when the label printer is working. The ribbon detection mechanism cooperates with the driven shaft and the rotation detection assembly. The driven shaft contacts the ribbon and assists in the ribbon conveying. The rotation detection assembly detects the rotation of the driven shaft. When the ribbon is conveyed normally, the driven shaft rotates normally. When the ribbon is broken, the ribbon separates from the driven shaft and the driven shaft stops rotating. Therefore, the rotation detection assembly can determine whether the ribbon is broken, and then determine whether the ribbon cassette is qualified.

[0008] The present application can simulate the actual use environment of the ribbon cassette through the cooperation of the mounting plate, the simulation mechanism and the ribbon detection mechanism, thereby improving the accuracy of the ribbon cassette detection results and thus improving the reliability of label production.

[0009] Optionally, the rotation detection component includes a detection blade and a photoelectric switch, the detection blade is arranged on the driven shaft, the photoelectric switch is mounted on the mounting plate, and the end of the detection blade away from the driven shaft is located in the photoelectric switch.

[0010] By adopting the above technical solution, the rotation detection component detects the coordination between the fan blades and the photoelectric switch. The detection blade is mounted on the driven shaft. When the driven shaft rotates, the detection blade rotates with it. A photoelectric switch is mounted on the mounting plate, and the detection blade is located within the photoelectric switch. When the driven shaft rotates, the detection blade passes by the photoelectric switch. The photoelectric switch can detect the passage of the detection blade and thus determine whether the driven shaft is rotating, thus satisfying the function of the rotation detection component.

[0011] Optionally, a plurality of detection blades are provided, and the plurality of detection blades are evenly spaced in sequence along the circumference of the driven shaft. When the driven shaft rotates, the plurality of detection blades pass through the photoelectric switch in sequence.

[0012] By adopting the above technical solution, by setting a number of detection blades on the driven shaft, and making the number of detection blades evenly spaced along the circumference of the driven shaft, when the driven shaft rotates, the number of detection blades will pass through the photoelectric switch in sequence, and the photoelectric switch can continuously detect the passage of the detection blades, thereby realizing continuous monitoring of the rotation of the driven shaft. The setting of multiple detection blades makes the detection result of the photoelectric switch unaffected by the rotation speed of the driven shaft, and can accurately detect each rotation of the driven shaft, thereby improving the sensitivity and reliability of the detection. At the same time, since the detection blades are evenly spaced along the circumference of the driven shaft, the distance between two adjacent detection blades is equal, which enables the photoelectric switch to accurately calculate the number of rotations of the driven shaft based on the number of times the detection blades pass, and then determine the conveying length of the ribbon.

[0013] Optionally, the driven shaft is slidingly connected to the mounting plate, a first adjustable driving member is provided on the mounting plate, the driven shaft is rotationally connected to the first adjustable driving member, and the first adjustable driving member is used to drive the driven shaft to move in a horizontal direction.

[0014] By adopting the above technical solution, since the driven shaft is slidably connected to the mounting plate, the first adjustable drive member drives the driven shaft to adjust its position. This allows the position of the driven shaft to be adjusted according to the actual situation of the ribbon in the ribbon cassette, ensuring that the driven shaft can accurately support the ribbon conveyance, thereby ensuring the stability and reliability of the ribbon conveyance process. At the same time, this adjustable design can also adjust the resistance force of the driven shaft to the ribbon according to the ribbon tension and conveying conditions, ensuring that the ribbon will not become loose or too tight during conveyance, further improving the accuracy and reliability of ribbon detection.

[0015] Optionally, the mounting assembly includes a photoelectric sensor, a mounting slot is provided on the mounting plate, the mounting slot is used to install the ribbon box, the photoelectric sensor is located on the side of the mounting plate where the mounting slot is provided, and the detection end of the photoelectric sensor is arranged toward the mounting slot.

[0016] By adopting the above technical solution, the installation component is arranged by the cooperation of the photoelectric sensor and the installation slot. The installation slot makes ribbon cassette installation more stable and convenient. The photoelectric sensor detects whether the ribbon cassette is in place, triggering the subsequent inspection process. Therefore, the photoelectric sensor can automatically detect the installation status of the ribbon cassette, improving the automation level of the inspection process and reducing the tediousness of manual operation.

[0017] Optionally, a clamping assembly is further provided on the mounting plate, and the clamping assembly includes a clamping piece, and the clamping piece is located on the side of the mounting plate where the mounting groove is provided, and the clamping piece is spaced apart from the mounting plate, and the clamping piece is arranged opposite to the mounting groove; a clamping driving piece is provided on the mounting plate, and the clamping driving piece is connected to the clamping piece, and the clamping driving piece is used to drive the clamping piece to move toward or away from the mounting plate.

[0018] By adopting the above technical solution, the clamping assembly is configured by cooperating with a clamping member and a clamping driver. The clamping driver can drive the clamping member toward or away from the mounting plate. After the photoelectric sensor detects that the ribbon cassette is in place, the clamping driver drives the clamping member toward the mounting plate, compressing the ribbon cassette. The clamping assembly ensures that the ribbon cassette is securely fixed to the mounting plate during the detection process, preventing inaccurate detection results caused by movement or shaking of the ribbon cassette.

[0020] By adopting the above technical solution, the clamping member is arranged in combination with the elastic block and the mounting shaft. When the clamping member is used to clamp the ribbon cassette, the elastic block contacts the ribbon cassette, and the elastic block can play a buffering and protective role to prevent the clamping member from damaging the ribbon cassette.

[0022] By adopting the above technical solution, the label tape detection mechanism is arranged through the coordination of the clamping claw, the force sensor and the pulling assembly. After the ribbon cassette is installed on the mounting plate, the clamping claw clamps the label tape at the outlet of the ribbon cassette, and the pulling assembly drives the clamping claw to move vertically downward to pull the label tape out of the ribbon cassette. During the process of pulling out the label tape, the force sensor detects the tension exerted on the clamping claw, thereby determining whether the label tape is pulled out smoothly. The setting of the label tape detection mechanism enables the automatic detection mechanism of this application to detect not only whether the ribbon is qualified, but also whether the label tape is qualified, thereby improving the comprehensiveness and accuracy of the ribbon cassette detection.

[0023] Optionally, a shearing mechanism is provided on the mounting plate, and the shearing mechanism includes pneumatic scissors and a pneumatic drive. The pneumatic scissors are provided on the mounting plate, and the pneumatic drive is connected to the pneumatic scissors. The pneumatic drive is used to drive the pneumatic scissors to cut the label tape; the pneumatic scissors are located between the mounting assembly and the clamp in the vertical direction.

[0024] By adopting the above technical solution, the shearing mechanism cooperates with the pneumatic scissors and the pneumatic drive.

[0039] The following is combined with Figure 1 -Attached Figure 8 , further details of this application are given.

[0040] An automatic detection mechanism for ribbon cartridges, referring to Figure 1 The apparatus comprises a mounting plate 1, a simulation mechanism 2, a ribbon detection mechanism 3, and a label tape detection mechanism 4. The simulation mechanism 2, the ribbon detection mechanism 3, and the label tape detection mechanism 4 are all arranged on the mounting plate 1. The simulation mechanism 2 and the ribbon detection mechanism 3 realize the detection of the ribbon, and the label tape detection mechanism 4 realizes the detection of the label tape.

[0041] Reference Figure 2 and Figure 3 The mounting plate 1 is provided with a mounting assembly 11, which includes a photoelectric sensor 112. A mounting slot 111 is provided on the mounting plate 1, and the photoelectric sensor 112 is located on the side of the mounting plate 1 where the mounting slot 111 is provided, with the detection end of the photoelectric sensor 112 facing the mounting slot 111. The opening of the mounting slot 111 facilitates the installation of the ribbon cassette 100 to be detected. After the ribbon cassette 100 is installed in the mounting slot 111, the photoelectric sensor 112 can detect whether the mounting cassette is in place.

[0042] Reference Figure 3 and Figure 4 A clamping assembly 12 is also provided on the mounting plate 1. The clamping assembly 12 includes a clamping member 121, an extension rod 122 and a clamping drive member 123. The extension rod 122 is located on the side of the mounting plate 1 where the photoelectric sensor 112 is provided. The extension rod 122 is arranged parallel to the mounting plate 1 and spaced apart. One end of the extension rod 122 is connected to the clamping drive member 123, and the other end is connected to the clamping member 121, and the clamping drive member 123 is arranged on the mounting seat 621.

[0043] After the photoelectric sensor 112 detects that the installation box is in place, the clamping drive 123 drives the extension rod 122 to rotate, so that the clamping member 121 is arranged opposite the ribbon box 100, and then the clamping drive 123 drives the clamping member 121 to move toward the mounting plate 1, so that the clamping member 121 presses the ribbon box 100, which can increase the stability of the installation of the ribbon box 100.

[0044] In this embodiment, refer to Figure 3 and Figure 4 The pressing drive member 123 adopts a rotary telescopic cylinder, or a combination of a telescopic cylinder and a rotary cylinder. The pressing drive member 123 is arranged on the mounting plate 1, and the driving end of the pressing drive member 123 is arranged perpendicular to the mounting plate 1. The driving end of the pressing drive member 123 is connected to one end of the extension rod 122. Under the drive of the pressing drive member 123, the extension rod 122 can rotate so that the pressing member 121 can be arranged directly opposite the mounting groove 111. The extension rod 122 can also move closer to or away from the mounting plate 1, so that the pressing member 121 can move closer to or away from the mounting plate 1, so that the pressing member 121 can press the ribbon cassette 100.

[0045] In this embodiment, refer to Figure 3 and Figure 4The pressing member 121 includes an elastic block 1211, which is located between the mounting plate 1 and the extension rod 122. A mounting shaft 1212 is provided between the elastic block 1211 and the extension rod 122. The axial direction of the mounting shaft 1212 is arranged along the spacing direction of the extension rod 122 and the mounting plate 1. One end of the mounting shaft 1212 is connected to the elastic block 1211, and the other end is connected to an end of the extension rod 122 away from the pressing drive member 123. The elastic block 1211 is made of rubber. The structural arrangement of the pressing member 121 is such that when the pressing member 121 presses the ribbon cassette 100, the elastic block 1211 contacts the ribbon cassette 100, thereby preventing the pressing member 121 from damaging the ribbon cassette 100.

[0046] Reference Figure 2 and Figure 3 The simulation mechanism 2 includes a drive shaft 21, which is located in the mounting groove 111. The axial direction of the drive shaft 21 is perpendicular to the mounting plate 1, and one end of the drive shaft 21 is rotatably connected to the bottom of the mounting groove 111.

[0047] Reference Figure 3 and Figure 5 The simulation mechanism 2 further includes a rotating drive member 22, a driving shaft 21 and a driving end of the rotating drive member 22 are coaxially connected, and the driving shaft 21 and the rotating drive member 22 are respectively located on both sides of the mounting plate 1. In this embodiment, the rotating drive member 22 is a servo motor.

[0048] When the ribbon cassette 100 is installed in the corresponding installation slot 111, the drive shaft 21 is inserted into the corresponding ribbon winding core in the ribbon cassette 100. At this time, under the drive of the rotation drive member 22, the drive shaft 21 drives the ribbon winding core in the ribbon cassette 100 to rotate, thereby winding the ribbon. At this time, the ribbon is transported in the ribbon cassette 100, which can simulate the stress conditions of the ribbon when the label printer is working.

[0049] Reference Figure 2 and Figure 6 The ribbon detection mechanism 3 includes a driven shaft 31 , which is arranged parallel to and spaced from the driving shaft 21 . The driven shaft 31 is located in the mounting groove 111 , and one end of the driven shaft 31 is rotatably connected to the bottom of the mounting groove 111 .

[0050] The driven shaft 31 is located at the exit of the ribbon cassette 100 , and during the ribbon conveying process, the driven shaft 31 supports the ribbon, guides the ribbon, and assists in conveying the ribbon.

[0051] Reference Figure 3 and Figure 5 The ribbon detection mechanism 3 also includes a rotation detection component 32, which is connected to one end of the driven shaft 31. The driven shaft 31 and the rotation detection component 32 are respectively located on both sides of the mounting plate 1, and the rotation detection component 32 is arranged on the mounting plate 1.

[0052] When the rotation detection assembly 32 detects that the driven shaft 31 is rotating, it means that the ribbon is in a normal conveying state. When the rotation detection assembly 32 detects that the driven shaft 31 is not rotating, it means that the ribbon is broken. This can automatically detect whether the ribbon is qualified.

[0053] In this embodiment, refer to Figure 3 and Figure 7 The rotation detection assembly 32 includes a plurality of detection blades 321, each of which is connected to the driven shaft 31. The plurality of detection blades 321 are evenly spaced along the circumference of the driven shaft 31, and the length direction of the detection blades 321 is arranged along the radial direction corresponding to the driven shaft 31. The rotation detection assembly 32 also includes a photoelectric switch 322, which is connected to the mounting plate 1, and the presence of the detection blades 321 is located in the photoelectric switch 322.

[0054] When the driven shaft 31 rotates, several detection blades 321 pass through the photoelectric switch 322 in sequence. At this time, the photoelectric switch 322 can detect the rotation of the driven shaft 31, thereby satisfying the function of the rotation detection component 32. Since the several detection blades 321 are arranged in a uniform interval, the distance between any two adjacent detection blades 321 is equal. This makes it possible to determine the number of rotations of the driven shaft 31 based on the number of times the several detection blades 321 pass through the photoelectric switch 322, and thus the conveying length of the ribbon can be determined. When the detected ribbon needs to be fully conveyed, the rotation detection component 32 of the present application can determine the length of the ribbon that can be used.

[0055] Reference Figure 3 and Figure 7 The bottom of the mounting slot 111 defines a first elongated hole 1111. One end of the driven shaft 31 is pluggably engaged with the first elongated hole 1111. The driven shaft 31 is spaced apart from or slidably connected to the inner sidewall of the first elongated hole 1111. A first adjustable driving member 33 is also provided on the mounting plate 1. The driving direction of the first adjustable driving member 33 is set along the length of the first elongated hole 1111. The first adjustable driving member 33 is connected to the mounting plate 1, and one end of the driven shaft 31 is rotationally connected to the first adjustable driving member 33.

[0056] Driven by the first adjustable drive member 33, the driven shaft 31 can move along the length of the first slot 1111. This allows the position of the driven shaft 31 to be adjusted, ensuring that the driven shaft 31 can support the ribbon. Furthermore, the conveyance of the ribbon can drive the driven shaft 31 to rotate, ensuring that the rotation detection assembly 32 can detect the rotation of the driven shaft 31. In this embodiment, the first adjustable drive member 33 is a finger cylinder.

[0057] Specifically, the length direction of the first slot 1111 is set according to actual conditions. The length direction of the first slot 1111 must meet the following requirements: ensuring that the position of the driven shaft 31 can be adjusted when the driven shaft 31 moves within the first slot 1111, thereby adjusting the resistance force of the driven shaft 31 against the ribbon. In this embodiment, the length direction of the first slot 1111 is set at an angle downward.

[0058] Reference Figure 1 and Figure 3 The automatic detection mechanism of the ribbon cassette also includes a label tape detection mechanism 4. The label tape mechanism includes a clamping claw 41, a force sensor 42 and a pulling component 43. The pulling component 43 is arranged on the mounting plate 1. The driving direction of the pulling component 43 is arranged in the vertical direction. The force sensor 42 is arranged at the driving end of the pulling component 43, and the pulling manipulator is arranged on the force sensor 42. The clamping claw 41 is located below the corresponding mounting slot 111 in the vertical direction.

[0059] In this embodiment, the gripper 41 is a finger cylinder, and the pulling component 43 is a linear module driven by a servo motor.

[0060] After the ribbon cassette 100 is installed in the corresponding installation slot 111, the clamping jaws 41 clamp the label tape at the outlet of the ribbon cassette 100. At this time, the pulling assembly 43 drives the clamping jaws 41 to move vertically downward, which can pull the label tape out of the ribbon cassette 100. During the process of pulling the label tape out, the force sensor 42 detects the pulling force applied to the clamping jaws 41, which can detect whether the smoothness of pulling out the label tape meets the requirements, and further determine whether the label tape is qualified.

[0061] Reference Figure 1 and Figure 2 A shearing mechanism 5 is also provided on the mounting plate 1, and the shearing mechanism 5 includes a pneumatic scissors 51 and a pneumatic driving member 52. A long groove 13 is provided on the mounting plate 1, and the long groove 13 is located on the lower side of the mounting groove 111. The pneumatic scissors 51 is inserted into the long groove 13, and the pneumatic driving member 52 is connected to the mounting plate 1, and the driving end of the pneumatic driving member 52 is connected to the pneumatic scissors 51.

[0062] When the label tape detection mechanism 4 pulls out the label tape, the label tape passes through the pneumatic scissors 51. After the label tape detection is completed, the pneumatic drive 52 drives the pneumatic scissors 51 to cut the label tape, which makes it easier to remove the ribbon box 100.

[0063] Reference Figure 1 and Figure 3 The mounting plate 1 is further provided with a belt guide mechanism 6 , which is located in the mounting groove 111 .

[0064] Reference Figure 2 and Figure 6The tape guide mechanism 6 includes a tape guide shaft 61, which is located in the mounting groove 111, and one end of the tape guide shaft 61 is rotatably connected to the bottom of the mounting groove 111. The tape guide shaft 61 is located between the pneumatic scissors 51 and the driven shaft 31 along the vertical direction.

[0065] Reference Figure 2 and Figure 6 After the ribbon cassette 100 is installed in the mounting slot 111 , the tape guide shaft 61 is located at the exit of the ribbon cassette 100 , and the label tape is transported downward through the tape guide shaft 61 , which can improve the stability of the label tape transport.

[0066] Reference Figure 3 and Figure 8 A second elongated hole 1112 is defined at the bottom of the mounting slot 111. One end of the tape guide shaft 61 is pluggably engaged with the second elongated hole 1112, and the tape guide shaft 61 is spaced apart from or slidably connected to the inner sidewall of the second elongated hole 1112. A second adjustable driving member 62 is also provided on the mounting plate 1. The driving direction of the second adjustable driving member 62 is set along the length direction of the second elongated hole 1112. The second adjustable driving member 62 is connected to the mounting plate 1, and one end of the tape guide shaft 61 is rotatably connected to the second adjustable driving member 62.

[0067] The second adjustable driving member 62 drives the tape guide shaft 61 to move, so as to adjust the position of the tape guide shaft 61, thereby ensuring that the tape guide shaft 61 can support the conveying of the label tape and improving the stability of the label tape conveying and discharging.

[0068] In this embodiment, refer to Figure 8 The second adjustable driving member 62 adopts a cylinder, and a transmission member 63 is arranged between the second adjustable driving member 62 and the guide belt shaft 61. The transmission member 63 ensures that the second adjustable driving member 62 drives the guide belt shaft 61 to move along the length direction of the second long hole 1112 through the setting of the mechanical structure.

[0069] Specifically, the length direction of the second slot 1112 is set according to actual conditions. The length direction of the second slot 1112 needs to meet the following requirements: when the tape guide shaft 61 moves within the second slot 1112, the position of the tape guide shaft 61 can be adjusted, thereby adjusting the resistance of the tape guide shaft 61 to the label tape. In this embodiment, the length direction of the second slot 1112 is set to be inclined downward.

[0070] In this embodiment, refer to Figure 1 and Figure 2Two inspection stations 14 are provided on the mounting plate 1, spaced apart horizontally. Each inspection station 14 is equipped with a mounting assembly 11, a simulation mechanism 2, a ribbon detection mechanism 3, a label tape detection mechanism 4, a cutting mechanism 5, and a tape guide mechanism 6. In this embodiment, the two label tape detection mechanisms 4 share a pulling assembly 43. The two inspection stations 14 on the mounting plate 1 can inspect the ribbon cassettes 100 simultaneously or sequentially, thereby improving the continuity and speed of ribbon cassette 100 inspection.

[0071] The implementation principle of the embodiment of the present application is: when the ribbon cassette 100 is detected, the ribbon cassette 100 is installed in the installation slot 111, and the photoelectric sensor 112 detects that the ribbon cassette 100 is installed in place, and then the detection of the ribbon cassette 100 begins.

[0072] When the ribbon is inspected: the rotating driving member 22 drives the driving shaft 21 to rotate, and the ribbon is then transported in the ribbon cassette 100. During the ribbon transport process, the ribbon passes through the driven shaft 31, and the driven shaft 31 supports the transport of the ribbon. The driven shaft 31 rotates as the ribbon is transported, and a number of detection blades 321 pass through the photoelectric switch 322 in sequence. The photoelectric switch 322 detects the rotation of the driven shaft 31. When the photoelectric switch 322 detects that the driven shaft 31 is rotating, this indicates that the ribbon can be used normally and the ribbon will not break during use, thereby determining that the ribbon in the ribbon cassette 100 is qualified. When the photoelectric switch 322 detects that the driven shaft 31 is not rotating, this indicates that the ribbon has broken, which can determine that the ribbon in the ribbon cassette 100 is unqualified.

[0073] When testing the label tape: the clamping jaw 41 clamps the label tape, and under the drive of the pulling component 43, the clamping jaw 41 pulls the label tape out of the ribbon box 100. At this time, the force sensor 42 detects the pulling force value, which can determine whether the label tape in the ribbon box 100 is pulled out smoothly, and then determine whether the label tape is qualified.
