Description
Technical Field
The invention relates to a jet printing device, in particular to a control system and method and a device for seamless jet printing of fabrics.
Background
The digital printer is a high-tech digital printing device which realizes the ink jet printing in a non-contact way with an object by using the information control technology and the direct output of a computer, and meets the requirements of people on the 'what you see is what you get' of printed products. Digital printers have penetrated into various fields of industrial production, and the digital textile printing industry is one of the important fields of application. The method does not need plate making in the earlier stage, not only adapts to the development trend of small batch, high quality and quick response, but also meets the environmental protection requirement of no pollution basically, so the method quickly becomes the new technical center of gravity of textile printing, and how to realize high-efficiency digital printing on non-planes such as cylindrical fabrics (socks, seamless underwear and the like) besides performing high-quality and high-efficiency digital printing on plane materials such as cloth or cut pieces and the like is a great demand point of market development at present.
Both flat and non-flat fabrics typically require a digital pattern of predetermined shape to be formed on the surface. When the digital jet printing equipment in the prior art sprays patterns on the surface of a fabric, the printing nozzle on the digital jet printing equipment is translated and the fabric is moved in a matching way, so that the digital patterns with preset shapes are formed on the surface of the fabric.
At least one row of holes are arranged on the printing nozzle, and a preset distance is reserved between two adjacent holes. During the printing process, the spray head moves once to form an effective spraying area. In the prior art, each time a printing nozzle finishes printing, the printing nozzle moves by a width distance corresponding to an effective spraying area. However, since the moving distance of the print head is always controlled to have a slight error, even if the print head is controlled to move by the PLC control system, the print head used for a long time always has an error, and thus the moving distance of the print head is smaller than or larger than the width distance corresponding to the effective spraying area.
Once the print head moves a distance greater than the corresponding width distance of the effective spray areas, it means that there is an unpainted seam between two adjacent effective spray areas, which will seriously affect the appearance of the fabric.
Once the distance traveled by the print head is less than the corresponding width distance of the effective spraying area, it means that two adjacent effective spraying areas will overlap, as mentioned in the solution disclosed in CN109733070A by the applicant: "the ejection width per movement of the head is set to 1/2 which is the effective ejection width, so that the print head 1 is divided into the front half ejection orifice and the rear half ejection orifice in the moving direction. When in printing, the back half spray hole is sprayed with a circle of pattern sprayed by the front half spray hole, so that the same pattern can be printed for 2 times, thereby effectively ensuring the printing effect and eliminating seams. Although this eliminates the seams and allows the spray to be clear, it tends to make the overlapped area more colorful due to the "same pattern printing 2 passes" and thus the appearance of the fabric is seriously affected.
On the other hand, when the spraying operation is performed on the cylindrical fabric, since the spray holes of the printing nozzle are all arranged on the same plane, distances between the plurality of rows of spray holes which are positioned on the same plane and are positioned in different row directions along a row direction defined by the axial direction of the cylindrical fabric and the surface of the curved cylindrical fabric are not equal. When the cylindrical fabric is sprayed, the vertical distances between the spray holes in different column directions and the cylindrical fabric are unequal, so that the ink sprayed from the spray holes in different column directions is not sprayed onto the cylindrical fabric at the same time, and if the ink is not corrected at the same time, the ink dots are not adhered to the fabric, the fabric moves, so that the ink dots are sprayed to wrong positions, and further wrong color register is easy to occur.

It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.
Referring to fig. 1 to 10, a device for seamless jet printing of fabric according to a preferred embodiment of the present invention can be used for pattern jet printing of fabric, wherein the fabric can be implemented as a flat fabric or a cylindrical fabric. When the fabric is subjected to jet printing, the equipment for seamless jet printing of the fabric can effectively prevent the seam from occurring during jet printing, and an overlapped jet printing area can not occur during jet printing, so that the phenomenon that the repeated jet printing area occurs on the pattern formed by jet printing to cause the color of part of the pattern to be dense is prevented.
Referring to fig. 1, in particular, the apparatus for seamless jet printing of fabric includes a jet printing assembly 10, a driving assembly 20, a moving assembly 30, and a control system 40.
The jet printing assembly 10 includes a nozzle 11 and an ink supply unit 12 communicating with the nozzle 11. At least one row of orifices 1101 is provided on the head 11, wherein the ink supply unit 12 is controllable to deliver ink to the head 11 and to eject ink from the orifices 1101 on the head 11. The nozzle 11 is movably coupled to the driving assembly 20 to move a predetermined distance to form a pattern of a next jet printing region when the nozzle 11 forms a pattern of a jet printing region on a fabric 700.
Specifically, the ink supply unit 12 may be implemented to include an ink containing tank, an ink supply mechanism provided to guide ink contained in the ink containing tank to the nozzle holes 1101 of the head 11, and an ink ejection mechanism provided to eject ink from the nozzle holes 1101 in a predetermined moving direction.
The movable assembly 30 is capable of carrying the fabric 700 and driving the fabric 700 to move, such as translating and rotating, under the nozzle 11 in a predetermined manner, so that the entire surface of the fabric 700 can be printed by the nozzle 11. When the fabric 700 is implemented as a tubular fabric, the movable assembly 30 may be implemented to include a driving motor and a roller for carrying the tubular fabric 700.
The driving assembly 20, the moving assembly 30 and the ink supply unit 12 are respectively and controllably connected to the control system 40 so as to be controlled by the control system 40 to complete the corresponding fabric jet printing operation.
In a preferred embodiment, the moving assembly 30 is configured to move simultaneously with the driving assembly 20 for driving the nozzle 11, so that the nozzle 11 can continuously perform the inkjet printing operation, thereby improving the inkjet printing efficiency.
In actual printing, the head 11 is driven by the driving assembly 20 to move along a printing width direction OA, wherein the direction of the head movement is defined as the printing width direction OA. When the fabric 700 is a flat fabric, the jet printing width direction OA may be any linear direction on the fabric 700, and accordingly, the moving member 30 drives the fabric 700 to move along a length direction perpendicular to the jet printing width direction OA, by such an arrangement. When the fabric 700 is a tubular fabric, the jet printing width direction OA is defined as an axial direction of the tubular fabric, and accordingly, the moving member 30 drives the fabric 700 to rotate about the axial direction.
In order to enable those skilled in the art to understand the preferred embodiment of the present invention, in at least one of the following examples, the fabric 700 is only illustrated as a tubular fabric, and those skilled in the art should understand that the present invention is not limited thereto.
It is worth mentioning that the arrangement direction of the rows of the nozzle holes 1101 on the head 11 is set to be parallel to the print width direction OA, and the minimum distance between the nozzle holes 1101 located at both ends of the print width direction OA on each row of the nozzle holes 1101 is defined as the maximum displacement width. In addition, the injection holes 1101 are equally spaced from the head 11, wherein a spacing between two adjacent injection holes 1101 is defined as a unit spacing.
Referring to fig. 2-9, and more particularly to fig. 9, the control system 40 includes a detection assembly 210, a processor 220, and a controller 230. The detection component 210 is configured to acquire parameter signals acquired via reception, such as: parameter signals related to characteristics (such as size) of a fabric to be jet-printed, jet-drawing parameter signals related to patterns to be jet-printed on the fabric 700, mechanical parameter signals, and the like, wherein the mechanical parameter signals include but are not limited to: parameters of the moving assembly 30 (e.g., rotational speed of rotation, speed of movement, etc.), parameters of the driving assembly 20 (e.g., rotational speed of rotation, speed of movement, etc.). It should be noted that the parameter signal related to the size of the fabric 700 to be jet printed and the jet image parameter signal to be jet printed on the surface of the fabric 700 may be input into the control system in advance, or may be obtained by an external sensor. Those skilled in the art will appreciate that the sensing assembly 210 may be implemented as various sensors, such as a speed sensor, a pressure sensor, and the like.
The processor 220 is electrically connected to the detecting assembly 210 to form a control strategy for controlling the movement of the driving assembly 20 and the moving assembly 30 according to the parameter signals collected by the processor 220, wherein the controller 230 is configured to execute the control strategy to generate and control the driving assembly 20 and the moving assembly 30.
Specifically, the detection component 210 is configured to acquire the parameter signal when performing the inkjet printing operation. The processor 220 determines a control strategy according to the parameter signal, wherein the control strategy corresponds to controlling the nozzle 11 to move along the print width direction OA, and before and after the head 11 moves in the print width direction OA, it appears that an overlap area 800 is formed, and at least a part of the ejection holes 1101 on the moved head 11 and at least a part of the ejection holes 1101 on the head 11 before the movement, appear to overlap each other, meanwhile, the control strategy also corresponds to controlling a part of the spray holes 1101 positioned in the overlapping area 800 to be sprayed when the spray head 11 is at the position before the movement, while the remaining other orifices 1101 located in the overlap region 800 are printed when the head 11 is in the moved position, to form at least one transitional inkjet zone 900 when the web 700 is inkjet printed at a location corresponding to the overlap area 800.
Preferably, each of the nozzle holes 1101a, which are located in the overlap region 800 and are printed when the head 11 is in the pre-movement position, and each of the nozzle holes 1101b, which are located in the overlap region 800 and are printed when the head 11 is in the post-movement position, appear to cross each other, as shown in fig. 6.
The controller 230 is configured to control the parameter signal related to the size of the inkjet printing fabric, the inkjet parameter signal related to the pattern to be inkjet printed on the fabric 700, and the mechanical parameter signal according to the control strategy, respectively, so that the pattern corresponding to the inkjet parameter signal is inkjet printed on the outer surface of the fabric 700.
It should be noted that, when the nozzle holes 1101 located in the overlapping area 800 are printed, a part of the nozzle holes 1101 are printed first, and the rest of the nozzle holes 1101 are printed later, so that even if the driving assembly 20 moves with a movement error during the movement, the nozzle holes 1101 located in the overlapping area 800 are only staggered to form an intersection, so that a seam caused by an excessive movement distance of the printing head does not occur in the pattern corresponding to the overlapping area 800 on the fabric 700, and a color of the pattern of the overlapping area 800 is not heavy due to the fact that at least a part of the nozzle holes 1101 on the head 11 after being driven and at least a part of the nozzle holes 1101 on the head 11 before being moved are repeatedly printed twice at any position on the overlapping area 800. In other words, the patterns in the intermediate ink-jet printing belt 900 are formed by ink-jet printing once, except that some patterns are formed by ink-jet printing of the nozzle holes 1101 located in the overlapping area 800 before the head 11 moves, and other patterns are formed by ink-jet printing of the nozzle holes 1101 located in the overlapping area 800 after the head 11 moves.
In one embodiment, when the fabric 700 is implemented as a flat fabric and the nozzle 11 is controlled to move once along the jet printing width direction OA to reach the other end of the fabric 700, the driving assembly 20 is controlled to stop operating for a predetermined time until the fabric 700 is moved by the movable assembly 30 along the length direction by a predetermined distance so that the nozzle holes 1101 of the nozzle 11 are aligned with the other portion of the fabric 700, and then the movable assembly 30 is controlled to stop and the driving assembly 20 is activated again to jet print the fabric 700 until the outer surface of the fabric 700 is completely jet printed.
It should be noted that, in this embodiment, when the fabric 700 is driven by the moving assembly 30 to move the predetermined distance along the length direction, the spray head 11 may also appear to form an overlapping region before and after moving along the length direction of the jet print, and at least a part of the spray holes 1101 on the spray head 11 after moving and at least a part of the spray holes 1101 on the spray head 11 before moving appear to overlap each other; and, by controlling a part of the spray holes 1101 located in the overlapping area to be sprayed at a position before the spray head 11 is moved, and the rest of the spray holes 1101 located in the overlapping area to be sprayed at a position after the spray head 11 is moved, at least one transition zone is formed at a position of the fabric 700 corresponding to the overlapping area. In this way, it is possible to prevent the seam from occurring not only in the jet printing width OA but also in the longitudinal direction of the jet printing in the plane of the fabric 700.
In the embodiment where the fabric 700 is implemented as a tubular fabric, when the nozzle 11 is controlled to move once along the jet printing width direction OA, the fabric 700 is driven by the movable assembly 30 to rotate slowly until all the annular surfaces of the fabric 700 aligned with the jet holes 1101 on the nozzle 11 are jet printed, the movable assembly 30 is controlled to stop operating, the driving assembly 20 is driven to drive the nozzle 11 to move once along the jet printing width direction OA, and then the driving assembly 20 is controlled to stop operating, and the movable assembly 30 is controlled to start again to drive the fabric 700 to rotate once, so that all the annular surfaces of the fabric 700 aligned with the jet holes 1101 on the nozzle 11 are jet printed. By repeating the above manner, the cylindrical fabric 700 can be entirely jet-printed.
Preferably, when the fabric 700 is implemented as a tubular fabric, the driving assembly 20 and the moving assembly 30 are controlled by the control system 40 to move simultaneously. In other words, in this preferred embodiment, the tubular fabric 700 is rotated by the moving assembly 30 at a predetermined rotation speed, and the nozzle 11 is simultaneously moved by the driving assembly 20 along the axial direction of the tubular fabric 700. In this manner, the ink ejected by the ejection head 11 to adhere to the outer surface of the web 700 appears to have a spiral orientation, and the outer surface of the cylindrical web 700 will form the transitional ink jet printing belt 900, as shown in fig. 8.
It can be understood that, in the present embodiment, since the spray head 11 and the movable assembly 30 are both moving at the same time, rather than intermittently moving, when the fabric 700 is spray printed in this way, the spray printing efficiency of the fabric 700 can be effectively improved.
It is worth mentioning that the difference between the colors of the transitional inkjet printing belt 900 and other areas of the fabric in fig. 8 is only a view for distinguishing the transitional inkjet printing belt 900, and after the tubular fabric 700 is completely inkjet printed, no seam or color difference exists on the outer surface of the tubular fabric 700, as shown in fig. 7.
It is also worth mentioning that the outer surface of the fabric 700 shown in fig. 7 and 8 is a single color (black), while in the actual jet printing operation, the color to be jet printed on the outer surface of the fabric 700 may be a color.
When the web 700 is a tubular web, the vertical heights of the nozzles 1101 of the nozzle 11 located in different rows to the web 700 are not uniform.
In an embodiment of the present invention, the detecting component 210 can further acquire a parameter signal related to a vertical height between the nozzle 11 and the web 700 with print, and the processor 220 can further form the control strategy related to controlling the moving speed of the driving component 20 and the moving component 30 according to the parameter signal, so that the ink ejected from one row of the nozzle 1101 which is located at the smallest vertical height on the surface of the web 700 and within a predetermined range from the other row of the nozzle 1101 can be printed on a predetermined position of the web 700 on the nozzle 11.
It is worth mentioning that the distance between the other rows of the orifices 1101 and the row of the orifices 1101 with the smallest vertical height on the surface of the web 700 can be obtained by a mathematical equation set formed by the constant speed of the movement of the nozzle, the diameter of the roller carrying the cylindrical web, the angular velocity of the movable assembly 30, and the diameter of the ink dots ejected from the orifices 1101. It is more worth mentioning that the distance between the spray holes 1101 on the spray head 11 and the minimum column of the vertical height of the surface of the fabric 700 is less than or equal to 5 mm.
The control system 40 executes the control strategy, so that the ink ejected from the ejection head 11 can be splashed to the position corresponding to the fabric 700.
It can be understood that the ink ejected from the ejection holes 1101, which are positioned in a predetermined range from the minimum row of the ejection holes 1101 on the vertical height of the head 11 and the surface of the web 700, can be ejected to a predetermined position of the web 700, so that the driving assembly 20 can prevent the ink ejected from the ejection holes 1101 from rotating the web 700 before the ink reaches the web 700, thereby preventing color misregistration.
It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are given by way of example only and are not limiting of the invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and described in the examples, and any variations or modifications of the embodiments of the present invention may be made without departing from the principles.
