Detailed Description
The technical solution of the present invention is described in further detail below with reference to the accompanying drawings. It is to be noted that any technical features and any technical solutions given do not limit the scope of the present invention, which shall include any equivalents or alternatives that may occur to those skilled in the art without inventive step.
According to an embodiment of the present invention, the printing of the fabric can be achieved by printing the aqueous ink on the temporary transfer printing carrier in a set pattern by using a printing roller such as a gravure printing roller, a flexographic printing roller, a circular printing roller or an offset printing roller, and then transferring the ink pattern on the temporary transfer printing carrier to the fabric, so as to finally form a printed pattern on the fabric. Here, a case where a gravure roll is used will be described as an example.
Referring to fig. 1, there is shown a transfer printing machine including a printing unit set according to the present invention for solving the problems and disadvantages of the prior art, which may include a central roll 1 and at least one printing couple unit 5 as a whole.
A center roller 1 is fixedly connected to the frame 12 through a bearing. The center roller 1 may be driven to rotate by a variable frequency motor 13. The center roll 1 may be a hard material roll whose surface is coated with rubber. The Shore hardness of the surface rubber is 85-90 degrees, and preferably 90 degrees. The outer diameter of the center roller 1 may be 1600-. Alternatively, the central roller can be filled with oil in the cavity, and the oil is heated by an electric heating rod arranged in the cavity, so that the temperature of the central roller 1 can be raised to 30-150 ℃. Obviously, the temperature of the central roller can be controlled by adopting other heating methods according to the actual requirement by a person skilled in the art. The central roller can be heated to raise the temperature, so that the printing temperature can be stably transferred, and the phenomenon that the product quality is unstable among batches due to large temperature difference formed by seasonal change or day-night change is avoided; and aiming at some high-count and high-density fabrics, the fabric fiber to be printed can be further expanded by heating, so that the dye-uptake and the dye-uptake speed are increased.
At least one (for example 2 to 8, 6 are shown in fig. 1) printing couple unit 5 is distributed on the periphery of the circumference of the central roller 1, and the printing couple unit or the printing couple units form a printing couple device according to the invention. Each printing couple unit 5 is independently provided with its advance towards the central roller 1 by respective advancing means, such as advancing cylinders 506. The thrust cylinders 506 are mounted on the body of each printing couple unit 5, for example on the frame 501 of the body.
Optionally, the transfer printing machine may further comprise a guide roller 4. More preferably, at least two guide rollers 4 are provided. At least one guide roller is provided adjacent to each of an inlet and an outlet of the fabric to be printed which contact the central roller. The guide roll 4 guides the fabric 2 into or out of the press section between the central roll 1 and the printing couple unit 5. Preferably, each guide roller 4 may be a hard material roller. The outer diameter of each guide roller may be 100-150 mm.
Optionally, drying boxes 7 may be disposed between the printing color group units 5 to ensure drying after printing ink is printed, so as to prevent color cross-color phenomenon between multiple color sets. In particular, with reference to figure 1, five drying cabinets 7 are provided, which are distributed alternately with six printing couple units 5 around the circumference of the central roll 1. In addition, the distance between the individual printing couple units may preferably be relatively fixed, i.e. the distance between the individual printing couple units does not substantially change after installation of the apparatus.
Optionally, the transfer printing machine may further comprise an in-line central roll washing system 15 arranged in the non-pressurized section of the central roll 1 and the printing couple unit 5. The online central roller cleaning system 15 comprises a cleaning device, a water scraping knife and an oven, wherein after the surface of the central roller 1 is cleaned by the cleaning device, the water on the surface of the central roller 1 is scraped by the water scraping knife, and then the surface of the central roller is dried by the oven, so that the continuous circulation application is realized. The cleaning device may include a showerhead and a brush.
FIG. 2 is a block diagram of a fast automatic register system for a decorating apparatus according to one embodiment of the present invention. As shown in fig. 2, the fast automatic register system for a printing apparatus including a plurality of printing couple units 5 (3 are illustrated in fig. 2, but the present invention is not limited thereto) includes a detector 16, and the detector 16 may be provided in one-to-one correspondence with each printing couple unit 5 for detecting color patches. For example, the detector may use a photo head that preferably has a fast response time and high color recognition accuracy. For example, the optical head may output an analog signal when encountering a color, and for example, the color difference may be related to the signal intensity, and preferably, the optical head may have a high color difference sensitivity. In addition, preferably, the optical head used in the present invention may have upper and lower two electric eyes.
In addition, as shown in fig. 2, the fast automatic register system according to an embodiment of the present invention further includes a plurality of local controllers 1701 respectively provided corresponding to the respective stamp color set units and/or one system controller 1702 centrally provided for the stamp devices. Each controller can adjust the position of the plate roller of the corresponding printing color group unit according to the registration deviation distance obtained by the detection of the color scale by the detector. Specifically, both the local controller 1701 provided in association with the pad unit and a system controller that can be provided independently of the pad unit, such as can be provided in association with the printing apparatus itself, can adjust the position of the plate roller of the corresponding pad unit in accordance with the registration deviation distance obtained by the detection of the color scale by the detector. That is, the automatic registration may be centrally controlled by the printing apparatus or may be dispersedly controlled at each color stack unit, which is not limited by the present invention.
In addition, the system controller 1702 may also perform overall control of the entire system or apparatus. The local controller 1701 may also perform other distributed controls on the decal set units. In addition, each color set unit does not necessarily correspond to one local controller, that is, several color set units may correspond to one local controller. It is assumed that a printing apparatus has six color set units, and two or three color set units may correspond to one controller, which is not limited in the present invention. However, each color group unit corresponds to one controller, and the operation and control as well as the maintenance and management of the equipment are more convenient.
Specifically, the color patches described above are printed, for example, via marks provided on a plate roller of each printing couple unit when the printing material (fabric) passes through the printing couple unit, and the printed color patches may correspond to the printing couple units one by one, for example, if six printing couple units are provided in the printing apparatus, the corresponding color patches may be printed one at a time when the printing material passes through each printing couple unit, and the pattern of the printed color patches may be rectangular, triangular, trapezoidal, or cross-shaped, and so on. Also, adjacent color patches may have a predetermined reference distance therebetween (e.g., 20mm or 30mm, etc., which may be referred to as "patch reference distance" hereinafter). In this way, the detector 16 provided corresponding to each printing couple unit can detect the color patch corresponding to the printing couple unit 5 passing through, for example, the second detector 16 provided in association with the second printing couple unit 5 can detect the second color patch corresponding to the second printing couple unit 5 just printed, then the distance between the second color patch and the first color patch (may be referred to as a primary color patch) corresponding to the first printing couple unit 5 can be obtained, and then the registration deviation distance of the second printing couple unit 5 can be obtained as the difference between the reference distance 20mm and the distance by comparing the reference distance. The detection of the patches corresponding to the other printed color set units and the calculation of the registration deviation distance are similar to those described above with reference to the second patch, except that the reference distance at this time is a multiple of the above-described reference distance, such as the reference distance at this time is 2 times the patch reference distance, i.e., 40mm, when the registration deviation distance of the third printed color set unit 5 is calculated.
Based on the registration deviation distance of the corresponding color set unit calculated by the method, the position of the plate roller of the corresponding color set unit can be adjusted, so that registration between the color set units can be automatically realized, namely, automatic plate alignment is realized.
In addition, as shown in fig. 2, the above-mentioned rapid automatic registration system may further preferably include a photoelectric encoder 18 connected to the main shaft of the printing apparatus and configured to track the rotation speed and position information of the plate rollers so as to dynamically adjust the rotation speed and/or position of the plate rollers by the controller.
In addition, preferably, the automatic register system may further include a plurality of sensors (not shown) provided corresponding to each of the plurality of pad units, the sensors being configured to detect a mark provided at a predetermined position on a roll of the corresponding pad unit, so as to adjust a position of the roll of the corresponding pad unit based on a detection time of the mark on the first pad unit or the previous pad unit, thereby aligning patterns printed on the respective pad units.
In addition, regarding registration, a general overprinting process is as follows: the process comprises the steps of plate loading, ink feeding and printing after starting, so that the process needs to be manually adjusted from the 2 nd color to the last color in sequence before automatic registration, material waste is caused, and particularly more waste materials are accumulated after plate changing for many times. In order to reduce the waste generated in this link, the pre-registration function (referred to as "pre-registration" for short) enables the user to perform the pre-registration function before the formal overprinting, so that the colors can be basically registered before the start-up overprinting.
In addition, due to relevant parameter errors and gear gaps, color pre-registration can be inaccurate, so that the quick automatic register system according to the embodiment of the invention can record correction values under various plate diameters according to experience and/or experiments, and can set a plurality of sets of pre-registration schemes, so that a user can conveniently call and use the system at any time.
The correction method may be as follows, for example. Assuming that the printing apparatus has 4 pad units, it is possible to perform pre-nesting with, for example, 5 sets (the values are merely examples and are not intended to be limiting) of printing plates with relatively large plate circumferences, and to record each color correction after each pad has stabilized. The 5 pre-sets of corrections are averaged and recorded as the "correction" for the corresponding color set unit of the pre-set scheme. Specifically, when recording the pre-trapping correction, the deviation is measured on the trapping cross line, and the error of each color is corrected to the error of the original color minus the error of the first color by taking the first color as a standard. For example: the second color cross is 5mm (+5) above the first color cross, the third color cross is 3mm (+3) above the first color cross, and the fourth color cross is 4mm (-4) below the first color cross; the corrected value of the second printing color group unit is 5mm, the corrected value of the third printing color group unit is 3mm, and the corrected value of the fourth printing color group unit is-4 mm.
In addition, preferably, the sensitivity of the detector can be adjusted manually or automatically to adjust the detection accuracy of the color patch to accurately find the color patch signal. Fig. 3 shows an example of targeting by adjusting the sensitivity of the detector.
In addition, it is preferable that the gate position of the detector be set by manually or automatically selecting the waveform of the detected color patch, and fig. 4 shows an example of setting/selecting the gate position of the detector.
In addition, the rapid automatic registration system according to the present invention may further include an input device such as a control panel, a mouse, a keyboard for inputting parameters, etc., and a display device for displaying information and enhancing user experience.
In addition, the rapid automatic registration system according to the present invention may further preferably include an image capturing device 19 such as a video camera and a still camera for facilitating a user to check the alignment of patterns on the printing material, etc., in real time or on demand.
In addition, the local controller 1701 or 1702 described above is also preferably capable of performing corresponding overprint parameter setting for other stamp color set units based on the overprint parameters of the first or previous stamp color set unit detected by the detector.
In addition, according to another embodiment of the present invention, there is provided a decorating kit apparatus which may include a plurality of decorating color set units 5 as shown in fig. 2. The printing part set device may further include a detector 16 disposed corresponding to each printing color set unit for detecting color patches, the color patches being printed when the printing material passes through each printing color set unit 5, wherein each of the printed color patches corresponds to each printing color set unit one by one, a predetermined reference distance (such as 20mm, 30mm, and the like) is provided between adjacent color patches, and the detector 16 disposed corresponding to each printing color set unit detects the passing color patch corresponding to the printing color set unit to obtain a registration deviation distance of the corresponding printing color set unit based on the reference distance. The printing unit set apparatus may further include a controller 1701 provided corresponding to each printing couple unit and configured to adjust a position of a plate roller of the printing couple unit 5 according to a registration deviation distance of the corresponding printing couple unit 5, thereby implementing automatic plate alignment. The automatic register mode of the printing part set device can be the same as or different from that of the rapid automatic register system.
In addition, preferably, the decorating kit apparatus may further include at least one sensor provided on the corresponding decorating color set unit for detecting a mark provided at a predetermined position on a roll of the corresponding decorating color set unit, so that the roll position of the corresponding decorating color set unit is adjusted by the controller 1701 or the system controller 1702 of the decorating color set unit based on the detection time of the mark on the first or previous decorating color set unit, thereby aligning the patterns printed on the respective decorating color set units.
In addition, preferably, the sensitivity of the above-described detector can be adjusted manually or automatically to adjust the detection accuracy of the color patch, as shown in fig. 3.
In addition, it is preferable that the gate position of the detector can be set by manually or automatically selecting the detected color scale, as shown in fig. 4.
According to an embodiment of the invention, a printing device is also provided, which comprises the printing sleeve device.
In addition, it is preferable that the printing apparatus further includes a controller 1701 (i.e., a system controller) provided independently of the printing section set device and configured to be able to adjust the position of the plate roller of the printing couple unit in accordance with the registration deviation distance of the printing couple unit.
In addition, the printing apparatus preferably further comprises a photoelectric encoder 18 connected to the main shaft of the printing apparatus and configured to track the rotational speed and position information of the plate rolls in order to dynamically adjust the rotational speed and/or position of the plate rolls by the controller.
Fig. 5 is a flow chart of a fast automatic register method for a printing apparatus according to an embodiment of the present invention. The printing apparatus includes a plurality of printing couple units 5, a detector 16, and a plurality of controllers 1701 provided corresponding to the respective printing couple units, or one controller 1702 provided in a centralized manner for the printing apparatus. The detector 16 may be disposed corresponding to each printing color group unit, and is used for detecting color patches.
As shown in fig. 3, the automatic plate-aligning method for a printing apparatus according to an embodiment of the present invention may include the steps of:
at step S1, color patches are printed as the ink passes through each print couple unit. Wherein each of the printed color patches corresponds to each printing color group unit one by one, and a predetermined reference distance (e.g., 20mm or 30mm, etc.) is provided between adjacent color patches.
At step S2, the detector provided corresponding to each of the pad units detects the passing color patch corresponding to the pad unit, so that the local controller or the system controller can obtain the registration deviation distance of the corresponding pad unit based on the above-mentioned predetermined reference distance.
In step S3, the position of the printing roller of the corresponding printing couple unit can be adjusted by the local controller or the system controller according to the registration deviation distance, so as to realize automatic registration.
In addition, preferably, the method further includes the following step S4: the roll speed and position information is tracked by a photoelectric encoder 18 connected to the spindle of the embossing apparatus to dynamically adjust the roll speed and/or position by a local or system controller.
In addition, preferably, the method further includes the following step S5: the marks provided at predetermined positions on the roll of the respective pad units are detected by a plurality of sensors (not shown) provided corresponding to the respective pad units, so that the roll positions of the respective pad units are adjusted based on the detection time of the mark on the first or previous pad unit, thereby aligning the patterns printed on the respective pad units.
In addition, the automatic register system and the printing apparatus according to the embodiment of the present invention may preferably further perform a single mark tracking function, and in particular, when printing a pigment print or a fluorescent dye print, since it is difficult for an electric eye of a photoelectric head to detect a color scale signal in a reflective or fluorescent condition, the color is tracked in a single mark manner so as to track the previously designated color (one color group without reflective or fluorescent). The single-standard tracking function refers to that only the upper electric eye of the photoelectric head is used for working, and the color-standard oscillogram is also used for detecting and correcting errors.
In addition, preferably, the automatic register system and the printing apparatus according to the embodiment of the present invention may further perform a label-free tracking function, and in particular, when printing a pigment print or a fluorescent dye print, since it is difficult for an electric eye of the photo head to detect a color mark signal in a reflective or fluorescent condition, the label-free tracking may also be performed in a label-free manner, in which the photo head performs tracking detection and error correction on a specific waveform formed by a single color in a printed pattern. The technology can also solve the problem of registration of the first color on the reverse side during double-sided opaque printing. The registration accuracy of the non-standard tracking may be lower than that of the standard-normal overprinting unit. In addition, the color scale of the non-standard tracing color is made into the last color during the plate making.
The printing sleeve device, the printing equipment and/or the automatic register system and the automatic register method according to the embodiment of the invention have better effects in the aspects of productivity and product quality. In addition, the overprinting capability of the system is far higher than that of an overprinting system of a traditional printing machine, the vehicle speed range can reach 8-600 m/min (the system has high-speed overprinting capability), and the automatic mark finding, longitudinal/transverse overprinting control, first color or front color tracking, pre-plate alignment, single mark tracking and/or mark-free tracking functions can be realized by the printing department set device, the printing equipment and/or the automatic plate aligning system and the automatic plate aligning method according to the embodiment of the invention.
