Technical Field

The present invention relates to a printing apparatus for printing on a fiber, paper, transfer film, or the like as a printing apparatus.

Background

In general, a printing apparatus is an apparatus for outputting an image such as a word or a figure on a material such as paper or fiber.

The printing apparatus can be applied in various forms, such as a plate type, a dot type, an inkjet type, and the like, according to a manner of outputting an image. As one example, in the case of an inkjet printer using an inkjet type print head, various designs and printing by image and data processing in a digital manner can be performed, and thus, it is widely used in various fields due to high usability.

Recently, with the increasing development of digital printing technology, usage cases are increasing not only in paper but also in the field of fiber dyeing industry requiring speed and durability of printers.

Typical fiber dyeing methods include dip dyeing in which a fabric is immersed in water to be dyed, printing in which an image is printed on a fiber to be dyed, transfer dyeing in which a pattern is transferred to a fiber after printing the pattern on a specific medium, and the like.

In the most widely used printing and dyeing, a complicated dyeing method is used in which after the pretreatment of the fiber, the pretreated fiber is printed with a pattern in various ways and is subjected to a heat treatment at high temperature and humidity, and then passed through a washing process. The sublimation transfer dyeing in the transfer dyeing method which can be regarded as a part of printing and dyeing is a method of transferring a pattern printed on a paper sheet to polyester fibers by high-heat punching after printing the pattern on the paper sheet by various means using sublimation transfer dye.

In recent years, with the great improvement in performance and speed of ink jet printers, ink jet printers are increasingly used as printers for printing and transfer dyeing from a printing and transfer dyeing system to one of printing methods.

The ink jet printing method is a method in which a design of a pattern or a printing method is digitally processed, so that the design of the pattern or the change of color can be freely performed, and mass production of small varieties or mass production of large varieties can be rapidly processed.

There are many types of fibers, but since the dyeing properties vary depending on the material of each fiber, ink suitable for the fiber properties should be selectively used in order to obtain good dyeing quality.

For example, reactive ink is generally used for dyeing vegetable materials such as cotton, acid ink is generally used for dyeing animal materials such as silk, and sublimation transfer ink is generally used for synthetic fibers such as polyester.

However, in the case of a mixed fiber in which several materials are mixed, it is difficult to obtain a good dyeing effect using a specific ink. For example, although a reactive ink or a transfer ink is used for a blend fiber in which cotton fibers and synthetic fibers are mixed, the requirements of both fibers cannot be satisfied at the same time, and thus a good dyeing effect cannot be obtained as a whole.

Particularly, in the case of fibers having a high blending ratio, there are problems that it is difficult to obtain a sharp color expression, adhesion is weak, and durability is deteriorated.

As an alternative to such a dyeing problem of blend fibers and the like or a method of obtaining a special dyeing effect, a dyeing method is used in which a pattern is printed on a film medium such as PET, and then an adhesive is applied only to the portion where the pattern is printed, and then the pattern is attached to the fibers by punching or the like, thereby obtaining a dyeing effect.

This method can dye a desired pattern while maintaining the original fibrous texture only by applying a binder to the pattern part, and thus, the pattern can be dyed by applying a binder thereto by various methods, but the following two representative methods are used.

One method is to apply a binder in a powder state to the entire pattern-printed film before the ink is not dried in a state where the pattern on the film is printed with the ink in a liquid or gel state, and then shake off or blow off the binder so that the binder is left only on the ink in a wet state. The other is a screen printing method similar to printing a pattern using ink, and a method of applying only an adhesive in a liquid state on the pattern.

However, since both methods are not a digital method, there is a limitation that the advantages of the digital method described above are not obtained.

Detailed Description

Hereinafter, the present invention will be described in detail with reference to exemplary drawings. In the drawings, reference numerals are added to the constituent elements, and it should be noted that the same reference numerals are used as much as possible for the same constituent elements even if they are shown in other drawings. In describing the present invention, it is to be understood that detailed descriptions of related known configurations or functions are omitted when it is determined that the detailed descriptions do not obscure the gist of the present invention.

Fig. 1 to 3 are schematic views illustrating printing on a transfer film or fiber by a printing apparatus according to embodiments of the present invention.

Referring to fig. a printing apparatus according to the present invention includes an ink head unit 100 and an adhesive head unit 200.

Wherein the ink head unit 100 ejects ink through a head.

Specifically, the ink head unit 100 has four primary color heads 110 and a white head 120.

At this time, the four primary color heads 110 jet-print four primary colors CMYK, i.e., cyan (cyan), magenta (violet), yellow (yellow), and black (black), thereby printing a fabric T as a printing object in a plurality of color patterns I, or the patterns I may be formed on a transfer film F of an intermediate medium body.

Meanwhile, the white head 120 shown in fig. 2 and 3 ejects white W, which is configured to print white as a background color on the fiber T as a printing object.

Further, a plurality of the ink head units 100 may be arranged in fig. 3, such as in the front and rear sides of the adhesive head unit, respectively.

In addition, although not shown in the drawings, the ink head unit 100 may further have another color head (not shown) that ejects another color as another color other than the four primary colors and white.

At this time, the other color may be one of Orange (Orange), Blue (Blue), Green (Green), Gray (Gray, Lk, LLk, etc.), Red (Red), fluorescent color, etc., and the other color head may be provided in plurality in the ink head unit 100.

In addition, the adhesive head unit 200 sprays an adhesive material through the head.

Specifically, the adhesive head unit 200 sprays different adhesive materials through a plurality of heads, respectively, and the different materials sprayed at this time are mixed into a multi-liquid type adhesive.

In general, the fiber attachment adhesive is in a state in which it is difficult to eject from the inkjet printer head, or even if ejected, the adhesive is easily hardened (solidified), and thus the nozzle of the expensive printer head is easily clogged, and there is a problem in that the expensive printer head is damaged.

Thereby, a one-component adhesive cannot be used as the adhesive ejected through the printer head. That is, the one-component adhesive hardens at the nozzle of the printer head when it hardens, causing the nozzle to easily become clogged.

As a solution to this, the present invention may use a multi-component adhesive as the adhesive to be ejected by the printer head. That is, the multi-component adhesive is an adhesive in which two or more kinds of raw materials are mixed.

As a specific example, the adhesive head unit 200 may have a first adhesive material head 210 and a second adhesive material head when manufacturing a two-component adhesive.

Wherein the first adhesive material head 210 sprays a first adhesive material, which may be a resin as one example.

In addition, the second adhesive material head 220 sprays a second adhesive material, which may be a hardener as one example, and the thus sprayed hardener is mixed with the previously sprayed resin to finally become an adhesive.

Such an adhesive head unit 200 may also have multiple heads to make a three-component adhesive or a four-component adhesive, or the like, multi-component adhesive.

As described above, the printing apparatus according to the present invention has the adhesive head unit 200 that ejects the adhesive material through the head together with the ink head unit 100, and performs printing on the fiber T by the inkjet method using the printer head or forms the pattern I on the transfer film F as the intermediate medium body, so that the fiber T including the blend fiber can be variously designed and printed by the image and data processing of the digital method, and good printing quality can be secured, and printing can be performed easily and the printing speed can be improved.

Further, the printing apparatus according to the present invention can be used for various printing objects such as paper, as well as fibers and transfer films.

In one aspect, the process of printing the fibres T by the printing device according to the invention is examined with reference to fig. 4 to 7.

Fig. 4 is a schematic view illustrating printing of a pattern by a printing apparatus and spraying of a bonding material according to the present invention, fig. 5 is a view illustrating that a plurality of bonding materials of fig. 4 are mixed to form an adhesive layer, fig. 6 is a view illustrating transferring of the pattern of a transfer film to a fiber, and fig. 7 is a view illustrating a fiber removing transfer film at the transfer pattern.

In printing the fibers T by the printing apparatus according to the present invention, as one example, the fibers T are not directly printed but printed using the transfer film F as an intermediate medium body for printing, which is as follows.

First, as shown in fig. 4, the ink head unit 100 is such that after the ink is ejected through the head to form the pattern I on the transfer film F, the adhesive head unit 200 ejects the first adhesive material B1 and the second adhesive material B2, respectively, and then the ejected first adhesive material B1 and second adhesive material B2 are mixed to form the adhesive layer B of the adhesive as shown in fig. 5.

Next, as shown in fig. 6, after the transfer film F is turned over to contact the fibers T as the printing object, the transfer film F is pressed by a pressing device so that the pattern I formed on the transfer film F is stuck to the fibers T through the adhesive layer B, and finally the pattern I is transferred to the fibers T as shown in fig. 7.

Fig. 8 is a view showing that capping members as head cleaning units are respectively mounted on a head of an ink head unit and a head of an adhesive head unit of the printing apparatus of fig. 1, and fig. 9 is an enlarged view showing the inside of the capping member of fig. 8.

Referring to fig. the printing apparatus according to the present invention further includes a head cleaning unit 300.

The head cleaning unit 300 is configured to protect the heads respectively provided at the ink head unit 100 and the adhesive head unit 200, and to maintain the surface of the head ejection portion cleanly.

Specifically, the head cleaning unit 300 includes a cover member 310, an absorption line 320.

Wherein the cap member 310 is provided in plural so as to fasten the head of the ink head unit 100 and the head of the adhesive head unit 200, respectively, when the printing operation is suspended, thereby cleaning the plural heads, respectively.

The closure member 310 may be formed using any conventional closure, and as an example, the structure shown in fig. 9 may be used.

At this time, it is preferable that the cap member 310 is formed of a rubber material in order to minimize an impact upon contact with the head.

Such a capping member 310 forms capping grooves 310a at an upper portion where the head is attached, and an absorption line 320 is connected to communicate with the capping grooves 310 a.

In addition, the inside of the cover groove 310a of the cover member 310 is filled with a buffer member 340 such as sponge, and a support iron net 350 is installed on the upper side of these buffer members 340.

In addition, the absorption line 320 absorbs the remaining ink remaining at the lower end portion of the head, or the remaining adhesive material, thereby cleaning the head.

These absorption lines 320 are provided in plural so as not to mix the absorbed substances, and different absorption lines are connected to different covers.

Specifically, an ink absorption line is connected to the cap member 310 fastened to the head of the ink head unit (100 of fig. 1) to absorb and remove the ink remaining in the head of the ink head unit 100, thereby purging the head of the ink head unit 100.

In addition, an adhesive material absorption line is connected to the capping members 310 respectively fastened to the plurality of heads of the adhesive head unit (200 of fig. 1), thereby absorbing and removing the adhesive material remaining at the heads of the adhesive head unit 200, thereby cleaning the heads of the adhesive head unit 200.

More specifically, the adhesive material suction lines are provided in plurality corresponding to the plurality of heads of the adhesive head unit, and different adhesive material suction lines are connected to different cap members 310 fastened to the plurality of heads of the adhesive head unit 200, respectively, in order not to mix the sucked adhesive materials.

Further, in order not to mix the absorbed substances, the ink absorption line is provided with an ink absorption pump (not shown), and the plurality of adhesive material absorption lines are respectively provided with different adhesive material absorption pumps (not shown).

At this time, if the adhesive material absorption lines are not provided in plurality independently of each other corresponding to the respective closure members 310 or have no additional absorption pump, respectively, the adhesive material will be mixed as an adhesive to block the absorption lines, resulting in the absorption pumps also malfunctioning.

In one aspect, an air supply line 330 may be connected for communication to the cover groove 310a of the cover member 310.

The air supply line 330 supplies air so that the inner space of the cap groove 310a, which is absorbed as negative pressure by the air of the absorption line 320, matches the atmospheric pressure, so that negative pressure shock is not applied to the head when the cap member 310 is separated from the head.

As a result, the printing apparatus according to the present invention includes the adhesive head unit 200 that ejects the plurality of adhesive materials to the plurality of heads through the heads, respectively, and forms the pattern I on the fiber T, the paper, the transfer film, or the like according to the printer head using the inkjet method, so that the fiber T, the paper, the transfer film, or the like including the blend fiber can be subjected to various designs and prints by image and data processing in a digital manner, and good print quality can be secured, thereby enabling printing to be performed easily and also improving the print speed.

In addition, the printing apparatus according to the present invention has the head cleaning unit 300, and the head cleaning unit 300 includes a plurality of cap members 310 to be fastened to respective heads at the time of suspension of operation, thereby protecting the heads respectively provided at the ink head unit 100 and the adhesive head unit 200, and maintaining the surface of the ejection portion of the heads cleanly.

As described above, the present invention is described with reference to the embodiments and the drawings, but the present invention is not limited to these, and those skilled in the art can make various modifications and variations within the scope of the technical idea of the present invention and the scope of the claims described below.
