Abstract
Description
Technical Field
[0001] The present invention relates to a blade cleaning module for a printer, a cleaning unit for a printer including the same, and a printer device including the same. More specifically, it relates to a blade cleaning module for a printer that performs the entire cleaning process of a print head without manual intervention, a cleaning unit for a printer including the same, and a printer device including the same. Background Art
[0002] All DTF (Direct to Film) printers currently sold on the market do not have the function of automatically removing the ink attached to the blade after cleaning. Therefore, the user faces the trouble of manually wiping the ink attached to the blade with a wiper every time after cleaning. This process brings inconvenience to the user, and some users sometimes neglect cleaning or do not clean at all due to this trouble.
[0003] The main disadvantages of the existing method are as follows: the operation efficiency decreases, the labor cost increases, the blade life is shortened, and the print head quality decreases. Generally, a DTF printer needs to be cleaned at least 4 times per period, but the number of cleaning times varies depending on the site conditions and humidity. Wiping the blade each time reduces the operation efficiency.
[0004] In the case of neglecting cleaning, it will lead to a shortened life of the print head and a decrease in output quality, resulting in a decrease in customer satisfaction. In addition, additional manpower is required to wipe the blade after cleaning, which will increase the labor cost. Finally, the method of wiping the blade with a wiper dipped in purified water will damage the blade surface, thus shortening the replacement cycle.

[0070] Next, preferred embodiments will be described with reference to the accompanying drawings. In this process, for the sake of clarity and convenience of description, the thickness of multiple lines shown in the figures or the dimensions of structural elements may be enlarged and shown. Also, the terms described later are terms defined in consideration of the functions in the present invention, and this term may be changed according to the intention or convention of the user or operator. Therefore, the definition of such terms should be based on the entire content of this specification.
[0071] In addition, when it is mentioned that a structural element "connects" or "contacts" with other structural elements, it should be understood that it can be directly connected or contacted with other structural elements, but there may also be other structural elements in the middle. On the contrary, when it is mentioned that a structural element "directly connects" or "directly contacts" with other structural elements, it should be understood that there are no other structural elements in the middle.
[0072] Unless clearly indicated in the context, the singular expressions include the plural expressions. Also, throughout this specification, when a certain part "includes" a certain structural element, unless there is a particularly contrary record, it means that other structural elements may also be included, rather than excluding other structural elements. The present invention can be specifically implemented in other specific forms without exceeding the necessary features of the present invention, which is obvious to those of ordinary skill in the technical field to which the present invention belongs.
[0073] In addition, the following embodiments do not limit the protection scope of the present invention, but are only presented as examples, and there may be various embodiments implemented through this technical idea. Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the figures, the same reference numerals represent the same structural elements.
[0074] Overall structure of the printer device
[0075] Figure 1 To show the front view of the printer device related to an embodiment of the present invention.
[0076] Refer to Figure 1, the printer device 1000 generally includes the following main structural elements: a printing unit 1100 for performing substantial printing; a cleaning unit 1200 for cleaning the print head to prevent problems caused by ink or the like remaining in the print head after printing; and a support unit 1300 for supporting the entire printing device and the like.
[0077] The printing unit 1100 uses DTP ink to print a design on a film. This is not a direct print on clothing or fabric, but rather after being temporarily printed on the film, it is transferred to the fabric through a heat treatment process. The cleaning unit 1200 is responsible for the maintenance management of the print head, preventing clogging of the ink nozzles, and always maintaining the printing quality through regular cleaning and maintenance repairs. The support unit 1300 supports the printing device, improves the printing precision, and prevents the material from moving or deforming randomly. Among them, the cleaning unit 1200 is the core element for continuously ensuring the performance of this system.
[0078] Working process of the cleaning unit
[0079] Figures 2a to 2c It is a front view showing the cleaning unit 1200 of the printer device 1000 according to the present invention. Figures 2a to 2c It is a diagram showing the working process of the cleaning unit 1200 of the printer device 1000 in sequence.
[0080] Figure 2a It shows the print head module 100 and the vacuum trapping station module 200. The main structural element of the print head module 100 is the print head 110. After completing the printing operation, it is necessary to remove the ink residue remaining on the print head 110 in order to maintain the printing quality. In this process, the vacuum trapping station module 200 plays an important role.
[0081] The vacuum trapping station module 200 includes a vacuum trapping unit 210, a vacuum pump 220, and a vacuum trapping housing 230. The vacuum trapping unit 210 is used to suck the ink remaining on the print head 110. For this purpose, the vacuum trapping unit 210 is connected to the vacuum pump 220. The distance between the print head 110 and the vacuum trapping unit 210 is adjusted by the vacuum trapping housing 230.
[0082] The height of the vacuum trapping housing 230 can be adjusted, and the vacuum trapping unit 210 is moved to a position close to the print head in order to suck the ink of the print head 110. Thus, the vacuum trapping unit 210 is closely attached to the print head 110 to effectively suck the ink.
[0083] To optimize the ink absorption efficiency, the vacuum pump 220 is activated after the print head 110 comes into contact with the vacuum trapping unit 210. However, when discharging ink, the vacuum pump 220 can operate when the print head 110 and the vacuum trapping unit 210 are not in contact. The vacuum pump 220 operates in a state where the vacuum trapping unit 210 is in close contact with the print head 110, thereby effectively removing the residual ink 250 from the print head 110.
[0084] According to Figure 2b , even after ink is trapped from the print head 110, a part of the ink remains in the print head in the form of bubbles. This is because there are limitations to completely removing ink by the vacuum suction method.
[0085] In a state where the vacuum trapping housing 230 is lowered, the ink remaining in the print head 110 requires an additional cleaning process. For this purpose, a blade cleaning module 300 will be introduced, which includes a cleaning blade 310.
[0086] According to Figure 2c , in the blade cleaning module 300, the cleaning blade 310 is rotated and raised to match the height of the print head. After that, the print head 110 passes through the position where the cleaning blade 310 is located and naturally undergoes the following process, that is, the cleaning blade wipes across the print head to physically remove the ink remaining on the surface of the print head.
[0087] In this case, the blade cleaning module 300 operates independently of the vacuum trapping station module 200. The vacuum trapping station module 200 ends its contact with the print head 110 by moving downward, but the blade cleaning module 300 does not move up or down. Instead, it comes into contact with the print head through the rotational movement of the cleaning blade 310.
[0088] After that, the ink remaining in the print head is removed by physical contact. The ink removal process described in Figure 2c will be described in detail later.
[0089] Working process of the blade cleaning module
[0090] Figure 3a and Figure 3b To show Figure 1 a perspective view of the blade cleaning module 300 according to an embodiment. Figure 4a and Figure 4b To view from the left Figure 3a and Figure 3b a perspective view of the blade cleaning module 300.
[0091] Figure 3a and Figure 4a is a state where the cleaning blade 310 is immersed in the cleaning liquid storage unit 330, Figure 3b andFigure 4b A diagram showing the state where the cleaning blade 310 rotates and rises for cleaning.
[0092] First, each structural element will be described, and its operation will be further described.
[0093] Referring to Figure 3a 、 Figure 3b 、 Figure 4a and Figure 4b , the object of the present invention is to reduce the cumbersome operations of users by automating the cleaning process of the nozzles of the print head 110, effectively remove ink, and protect the nozzles. The main structural elements and functions are as follows.
[0094] The blade cleaning module 300 mainly functions to remove the ink on the surface of the print head nozzles. The cleaning blade 310 is designed to be able to contact the nozzle surface of the print head, and performs the cleaning process through the rising and falling functions based on rotation.
[0095] The blade rotation control unit 320 adjusts the rotation of the blade to cause the cleaning blade 310 to rise or immerse the cleaning blade 310 in the cleaning liquid in the cleaning liquid storage unit 330 described later.
[0096] The cleaning liquid storage unit 330 stores the cleaning liquid used in the cleaning process, which enables the cleaning blade 310 that has completed cleaning to be immersed and cleaned by the cleaning liquid. As needed, the cleaning liquid supply units 340A, 340B supply the cleaning liquid to the blade. The cleaning liquid discharge units 350A, 350B discharge the used cleaning liquid. The supply of the cleaning liquid and the discharge of the used cleaning liquid are performed in sequence according to the cleaning program.
[0097] The blade rotation identification unit 360 detects the rotation state of the blade, and precise control can be performed through the sensor indicator 361 and the rotation identification sensor 362. Specifically, the sensor indicator 361 rotates together with the rotation of the cleaning blade 310. When the sensor indicator 361 rotates, the rotation identification sensor 362 can generate a rotation end signal by detecting at the rotation end position.
[0098] The blade rotation control unit 320 participates in the rising and falling of the blade. The blade rotation control unit 320 can be implemented as a stepper motor. When the blade cleaning process is required, the stepper motor will operate, and the cleaning blade 310 will rotate in the clockwise direction. When the sensor indicator 361 reaches the detection area of the rotation identification sensor 362, the stepper motor will stop operating. In this case, the cleaning blade 310 is in an upright state at the optimal height capable of wiping the nozzle surface of the print head 110.
[0099] In addition to the physical indicator sensor method, the blade rotation recognition unit 360 can also use the logical control of the blade rotation control unit 320 and can be implemented in various structures according to the environment.
[0100] The X-axis adjustment position gauge 370 and the Y-axis position adjustment gauge 380 adjust the accurate position of the blade. The X-axis adjustment position gauge 370 adjusts the cleaning blade 310 in the X-axis direction, and the Y-axis position adjustment gauge 380 adjusts the cleaning blade 310 in the Y-axis direction. It has a part that can be adjusted along the X-axis and Y-axis directions and is fixed by bolts.
[0101] The splash guard portion 390 prevents cleaning water and the like that may occur during the cleaning process from splashing downward.
[0102] Figure 5a It is a flowchart showing the cleaning process of the printer device according to an embodiment of the present invention. Figure 5b To show Figure 5a The flowchart of the ink suction process in the cleaning process according to the embodiment of. Figure 5c To show Figure 5a The flowchart of the blade cleaning process in the cleaning process according to the embodiment of.
[0103] Referring to Figure 5a A normal printing process S100 is performed. After each unit of the printing process is performed, a process S200 of checking whether it is a condition that needs to be cleaned is executed. In this case, when it is determined that cleaning is required, an ink suction process S300, a blade cleaning process S400, and a flash evaporation process S500 will be performed.
[0104] Referring to Figure 5b And Figure 5c The specific procedures will be described.
[0105] First, referring to Figure 5b The print head 110 first moves to the designated cleaning position (step S310). In this case, at least one print head 110 corresponds to at least one vacuum trapping portion 210 at the corresponding position respectively.
[0106] After that, the vacuum trapping portion 210 will rise (step S320). Based on this, the print head 110 and the vacuum trapping portion 210 will finally come into contact (step S330). After the contact, the vacuum pump 220 will be driven to trap the ink (step S340). After the trapping is completed, the vacuum pump 220 descends to the vacuum trapping portion 210 (step S350). Then it enters the next cleaning step.
[0107] Referring to Figure 5c, the cleaning blade 310 rotates through the blade rotation control unit 320 and rises (step S410). Among them, the blade cleaning module 300 does not perform separate ascending and descending movements, and the cleaning blade 310 only rises through the rotational movement of the blade rotation control unit 320.
[0108] After rising, the print head 110 moves to the position where the cleaning blade 310 is located. The print head 110 moves toward the cleaning blade 310 to erase the ink attached to the head, and the cleaning blade 310 scrapes off the ink attached to the nozzle surface of the print head 110 (step S420).
[0109] After that, after scraping off the ink of the print head 110, the cleaning blade 310 descends by rotational movement. In this case, the cleaning blade 310 will be immersed in the cleaning liquid storage unit 330 storing the cleaning liquid, and the ink attached to the cleaning blade 310 is cleaned by the cleaning liquid. Through this process, even if the blade is cleaned multiple times, the ink attached to the cleaning blade 310 remains in the state of being previously cleaned by the cleaning liquid.
[0110] The cleaning of the cleaning blade 310 in this way can prevent damage to the nozzle surface, and the user does not need to clean the blade every time.
[0111] Independently of this, the function of replenishing and discharging the cleaning liquid to the cleaning liquid storage unit 330 is performed. Purified water can be used as the cleaning liquid. The above-mentioned purified water can dissolve the water-based ink attached to the cleaning blade 310. First, the cleaning liquid is supplied through the cleaning liquid supply units 340A and 340B (step S440).
[0112] The cleaning blade 310 rotates and moves between the cleaning liquids. During this process, the cleaning liquid will dilute the ink. The blade edge of the cleaning blade 310 will be immersed in the cleaning liquid replenished to the cleaning liquid storage unit 330, and during this process, the ink is dissolved by the cleaning liquid.
[0113] During this process, the contaminated cleaning liquid stored in the cleaning liquid storage unit 330 will be discharged through the cleaning liquid discharge units 350A and 350B (step S450). The cleaning liquid inside the cleaning liquid storage unit 330 contaminated by ink due to continuous cleaning will be discharged to the outside. Thus, the cleaning liquid with a purity above a specified level is maintained, which can prevent the time for dissolving the ink attached to the cleaning blade 310 from being delayed. The contaminated purified water as the discharged cleaning liquid will be discharged to a separate storage.
[0114] Additional embodiments
[0115] Figures 6a to 6c Shows the vacuum trapping station module and the blade cleaning module according to another embodiment of the present invention.
[0116] Refer to Figure 6a , the vacuum trapping station module 200 includes two vacuum trapping parts 210. The number of such vacuum trapping parts 210 may correspond to the number of print heads 110 of the print head module 100 and include multiple vacuum trapping parts 210.
[0117] In Figure 6b case, the vacuum trapping station module 200 includes a total of five vacuum trapping parts 210. Figure 6a It is a diagram showing a plate included in the upper part of the vacuum trapping part 210, Figure 6b It is a diagram removing such a plate. Similarly, a total of five vacuum trapping parts 210 may correspond to the number and position of the print heads 110 of the print head module 100 respectively and include multiple vacuum trapping parts 210. The number of vacuum trapping parts 210 can be various.
[0118] Refer back to Figure 6a and Figure 6b , the length and position of the cleaning blade 310 can be configured to be able to contact the length of the range of the print head 110 evenly. In the figure, the position and number of the print heads 110 can be inferred from the arrangement position of the vacuum trapping parts 210. When such a print head 110 passes through the blade cleaning module 300, it can all pass through the cleaning blade 310.
[0119] In Figure 6c case, there are two cleaning blades 310, and the two above-mentioned cleaning blades 310 are respectively arranged corresponding to the positions of the vacuum trapping parts 210. Similarly, the cleaning blades 310 can be arranged to match the positions of the print heads 110 corresponding to the vacuum trapping parts 210, and the print heads 110 are cleaned corresponding to each cleaning blade 310.
[0120] Figure 7 It is a cross-sectional view showing the blade cleaning module according to another embodiment of the present invention.
[0121] Refer to Figure 7 , the blade cleaning module 300 of this embodiment includes a non-interference reduced storage chamber 331 that enables the cleaning liquid storage part 330 not to interfere with the rotation of the above-mentioned cleaning blade 310 and reduces the storage capacity of the cleaning liquid.
[0122] This non-interference reduced storage chamber 331 functions to not affect the movement of the cleaning blade 310 and reduce the storage capacity of the cleaning liquid. This non-interference reduced storage chamber 331 functions to effectively reduce the waste water volume of the discharged cleaning liquid.
[0123] On the other hand, the cleaning liquid storage unit 330 may include a vortex generating groove 332 that causes the cleaning liquid to vortex to promote the cleaning of the cleaning blade 310 when the cleaning blade 310 performs a rotational operation. The vortex generating groove 332 maximizes the cleaning effect of the cleaning blade 310 by utilizing the dynamic vortex generated within the cleaning liquid storage unit 330.
[0124] Specifically, the vortex generating groove 332 of the blade cleaning module 300 may be formed by a plurality of elongated grooves recessed along the major axis of a cylinder shape. When the cleaning blade 310 rotates and moves within the cleaning liquid storage unit 330, such grooves effectively generate a vortex. In particular, the above-mentioned grooves include a surface close to the cleaning blade 310 and a surface far from the cleaning blade 310, and when the cleaning blade 310 rotates and moves, it promotes the generation of a vortex of the cleaning liquid between them. This makes the cleaning process of the cleaning blade 310 more effective. The structure of the groove triggers a vortex through interaction with the flow of the cleaning liquid, thereby strengthening the cleaning process. A plurality of such vortex generating grooves 332 are formed, and the cross-section can be in various shapes such as circular and triangular. In particular, when the cross-section is circular, a vortex can be formed more naturally.
[0125] As described above, although the embodiments are illustrated through the defined drawings, those of ordinary skill in the art can make various technical modifications and deformations based on the above content. For example, even if the technologies described above are executed in an order different from the methods described above, and / or the structural elements such as the systems, structures, devices, and circuits described above are combined or assembled in a form different from the methods described above, or are replaced by other structural elements or equivalent technical solutions, appropriate results can still be achieved. Therefore, other embodiments, other examples, and contents equivalent to the scope claimed by the invention also fall within the scope of the claims described below.
