Description

Textile heating device, textile printing method and textile printing device

The present invention relates to a printing heating apparatus, a printing method, and a printing apparatus that are easy to use and safe for anyone who is not a dedicated operator.

For fabrics such as cotton cloth, the paper is stretched using a heat press machine as a pre-printing process, printed with an ink-jet printer, and heated with the ink (dye) printed using the same heat press machine as a post-process. Such a printing method for fixing is put into practical use. Alternatively, in the case of other fabric types, chemical treatment is performed as a pre-printing process, the paper is stretched with a heat press, and then printing is performed, followed by a fixing process or a cleaning process suitable for each ink. There is also a method.

Hereinafter, with reference to FIGS. 1 to 5, as a typical example, a conventional method for printing on a cotton cloth (for example, a cotton T-shirt) will be described. First, FIG. 1 shows a wrinkle stretching process in a heat press machine 1 used as a pre-printing process. First, the fabric 5 is placed on the base 2 of the heat press machine, and as shown by the symbol S, the folds of the fabric 5 are roughly extended. And the handle 4 is pushed down, the hot-pressing plate 3 is pressed against the fabric 5, the wrinkles are stretched by pressurization and heating, and fuzzing is also suppressed. This heat press machine is widely used as a heating device with a high degree of completion, and also for heat transfer of images to fabrics and application of patches. For example, see FIG. In Patent Document 1, a heating plate is inserted in the base 2 and the upper hot pressing plate is used as a simple pressing plate. However, in general, many configurations shown in FIG. 1 can be seen.

Next, the printing process is performed. As shown in FIG. 2, the fabric 5 that has been stretched is placed on the platen 7 of the textile printer 6Ms from a heat press machine, taking care not to become wrinkles. Then, as indicated by symbol A, the placement position (up / down / left / right) of the fabric 5 on the platen is adjusted with care so as not to cause distortion at a desired location. In addition, as shown by the symbol S, the wrinkles generated when the fabric is placed are gently stretched. Next, as shown in FIG. 3, as an example, the frame number 9 is pushed from above the fabric 5, and the fabric is pressed against the platen and set. The fabric protruding from the platen is folded inside the carriage 8 as indicated by symbol T so that the fabric does not interfere with the printer mechanism when entering and exiting the printer 6Ms. Subsequently, according to a printing instruction, the carriage 8 sends the platen 7 on which the fabric 5 is placed to the printer 6Ms, prints it, and sends it out when it is finished. This is shown in the lower right diagram of FIG.

Subsequently, heat-fixing of the post-treated dye to the fabric is performed. As shown in FIG. 4, the printed fabric 5 from the printer 6Ms is carefully removed from the platen 7 of the printer as indicated by an arrow a, and transferred to the heat press 1 as indicated by an arrow b. Next, the fabric 5 is placed on the base 2 again as indicated by an arrow c. Then, as shown by the symbol S in FIG. 5, the wrinkle of the fabric 5 is corrected, and then the handle 4 of the heat press machine is pushed down, and the heating plate 3 is pressurized and heated to the fabric 5 to heat and fix the ink to the fabric 5. In this figure, the wrinkle is stretched by the palm of a place where printing is not performed. However, since the printed surface must not be touched, it is necessary to devise such as stretching by holding both ends of the fabric (not shown).

Japanese Patent Laid-Open No. 1996-058060 JP 2016-113718 A JP 2013-096017 A Japanese Patent Laid-Open No. 1993-056865

Inkjet (IJ) large-scale printing equipment is used as a full-fledged textile production machine, and products aimed at further miniaturization are on the market. This is an IJ printer in which the size of the printing cloth is limited to A3 size or smaller. The size of the printer is small, for example, a floor area of about 1 m by 1 m and a weight of about 80 kg to 110 kg. In addition to this, a heat press machine is added, and it is handled by a full-time operator who is familiar with handling. However, in reality, this is not a small device. The price is much higher than 1 million yen. Therefore, this will be referred to as a “medium-size printing apparatus” for convenience. This has been described as 6Ms in the explanatory drawings so far. This medium-sized textile printing device would be worth it for use in large print shops and net print service bases.

A wonderful technology called textile printing that gives people a lot of fun from a long time ago. When you deepen your thoughts here again, the potential of over-the-counter printing services at street clothing stores, stationery stores, photo studios, souvenir shops, etc. It seems that needs are extremely large. Or it might be fun to imagine that there is a printing device that can be used for kindergartens, schools, community circle activities and nursing homes. However, until now, there has been no printing apparatus or method that can do this. When a new idea is studied with respect to the above-described conventional technology, problems with the printing apparatus and method realization in such stores and kindergartens are identified. It is (1) does not take a place (small installation floor space) and is as small as a personal printer. (2) It is not a work by a dedicated operator as in the past, and it is easy for anyone to operate. These are three points: (3) In addition, it is natural that safety can be secured without any problem even if handled by ordinary people.

Among the above problems, regarding (1), a solution is proposed in Patent Document 2: Japanese Patent Application Laid-Open No. 2016-113718. Here, the idea is to devise a mechanistic solution for the miniaturization of the printing apparatus and to realize the miniaturization even if the print size, the type of fabric, and the color are limited. The apparatus proposed here will be referred to as a “miniature textile printing apparatus” and will be denoted as 6Ss in the following explanatory drawings. Furthermore, this patent document states that “a small printing device that can be realized by limiting to a specific printing size, type of fabric, and color, and general-purpose printing that covers other printing sizes, types of fabric, and colors that cannot be achieved with this. We have devised a system that can respond to all demands in combination with textile printing equipment. The present invention proposal also adopts this concept with respect to downsizing of the printing apparatus. Furthermore, it aims at making the installation floor area of all the apparatuses used further small like a personal printer. In addition, these three points that provide means for solving the problems (2) and (3) which have not been handled so far, are the object of the present invention.

First, the ease of handling problem (2) will be described in detail. In

paragraphs

3, 4 and 5, the printing procedure of the conventional medium-sized printing apparatus is described with reference to FIGS. The point here is that the object to be handled is a flexible, unshaped fabric unlike paper. The fabric is touched, moved, and set many times during a series of printing operations. Care must be taken to ensure that the printed surface does not wrinkle every time it is set. In particular, great care must be taken not to touch the printed fabric. This is because the printed image is distorted or the touched object becomes dirty. Here is one reason for requiring a dedicated operator.

Examples of clever handling of fabrics having hanging parts can be seen in FIGS. This is shown in FIG. The idea is to handle the fabric by fixing the fabric with a number 9 frame element. In addition, there is a number 10 hanging section, which is used to change the location of the fabric. FIG. (F6-1) is a diagram simulating how to handle without any special device, and FIG. (F6-2) is a device of Patent Document 3. This eliminates the need to touch the printed surface of the fabric. However, even when the fabric is set in the apparatus, the alignment must be performed each time and the fabric 11 protruding from the frame element 9 must be folded. The ease of handling is incomplete.

Problem (3): The surface of the heating plate of the heat press machine is a high temperature of about 160 degrees when handling cotton cloth. There is a risk of burns and should never be touched. The conventional heat press machine is dangerous because the hot plate is exposed. There is a need for a new heating apparatus that satisfies the required functions in safety and in place of this heat press machine. Although the order has changed, it is not enough to reduce the size of the textile printer for the problem (1). Conventionally, two devices, a printer and a heat press, are combined to form an installation floor area. If both are put together in one unit and printing and pre-processing and post-processing are performed automatically, the size of one unit is enough, but the size becomes huge, so it is nonsense and what is the solution? Don't be. The present invention solves the three problems (1), (2), and (3) that such a conventional printing method has had, and minimizes the floor space occupied by the installation of printing apparatuses that can be placed in stores. In addition, an object is to realize a printing apparatus and a printing method mainly including a printing heating apparatus that ensures the simplicity and safety that anyone can handle.

Problem solving means 1 is a printing heating device for performing a heat treatment on a fabric placed on the upper surface of a cassette, the cassette comprising a box-shaped container and a flat plate arranged on the upper surface, and the heating device for printing is Before printing on the body placed at least on the upper surface of the inserted cassette, the insertion port for inserting / removing the cassette provided in the main body, the main body covered with at least the heating plate and the entire surface containing the heating plate A heating apparatus for textile printing comprising a heating plate position switching mechanism for performing a pressure heating treatment as a process and a non-contact heating treatment as a post-printing process with a single heating plate.

Problem solving means 2 is a textile printing method using a textile placement cassette comprising a textile printer, a textile heating device, a box-shaped container and a flat plate arranged on the upper surface thereof. First, the textile is placed on the flat plate of the cassette. The fabric protruding from the flat plate is folded and stored in a cassette, and then the cassette on which this fabric is placed is inserted into a printing heating device and subjected to pressure heating treatment as a pre-printing treatment, and then the cassette on which the fabric is placed. Is a textile printing method in which a textile printer is loaded, printing is performed on the fabric, a cassette on which the printed fabric is placed is inserted into a textile heating device, and non-contact heat treatment is performed as post-printing processing. .

The problem solving means 3 is an apparatus in which the printing heating apparatus described in the problem solving means 1 that handles the pre-processing and post-processing steps of printing and the miniaturized printing printer are arranged one above the other. It is a textile printing device characterized by minimizing the total floor space dedicated to installation.

The other problem-solving means (A) uses the printing heating apparatus described in Problem-solving means 1 as a pre-printing processing apparatus, sets the heating plate to any set temperature in the range of 100 ° C. to 180 ° C., and applies it to the fabric. The pre-printing method is characterized in that the pressure is set in the range of 600 Pascals to 30 Pascals and the fabric is pressurized and heated.

Still another problem-solving means (B) uses the printing heating apparatus described in Problem-solving means 1 as a post-printing processing apparatus, and sets the proximity distance between the heating plate and the fabric to any distance in the range of 1 to 5 mm, The post-printing processing method is characterized in that the surface temperature of the heating plate is set to any temperature within a range of 170 ° C. to 200 ° C., and non-contact heating is performed on the fabric.

The action by the problem solving means 1 is as follows. A heating device for textile printing that is helpful is a so-called toaster. A copy of FIG. 1 of Patent Document 4 was placed as number 12 in FIG. 7 of the present application. Sections (F7-1) and (F7-2) of FIG. 7 schematically show the cross section. Reference numeral 13 denotes a toaster housing, and the heater 14 is housed in the housing 13 and is not touched by the user. The user opens the toaster door 15 as shown in FIG. (F7-1), and puts the object B to be heated such as bread on the placement net 16 that has been slid out. Next, the door 15 is closed and heated as shown in the figure (F7-2).

FIG. 8 shows a cross-sectional view of the printing heating device 17 of the present invention. The main body of the heating device 17 for textile printing is covered with the entire exterior so that the user cannot touch the heating plate 20 disposed inside. At the time of use, the door 19 of the printing heating device that closes the cassette insertion opening 18 is opened, and the cassette 23 on which the fabric 5 described later is placed is inserted. It is a figure (F8-1). In the heating apparatus for textile printing, the heating plate 20 backed by the heat insulating base 21 is waiting at a position apart from the upper part. FIG. (F8-2) shows that the cassette 23 has been inserted and the heating plate is waiting.

(F8-3) is a front sectional view of this state as seen from the cassette insertion slot side. A pair of eccentric cams 22 (in the figure, the major axis side is shown as 22-2 in the upper position) are provided on the insertion port sides on both sides close to the cassette. A similar eccentric cam pair is also provided on the opposite back side. The function of the eccentric cam will be described with reference to the cross-sectional view of FIG. Specifically, the eccentric cam is placed at a position to receive the end portion of the heat-insulating base plate 21 that has been lowered by a heating plate vertical movement mechanism described later. (F9-1) in FIG. 9 shows a set position in which the minor axis side of the eccentric cam is upward. Since the highest point of the eccentric cam 22-1 is set lower than the position of the cloth 5 on the cassette 23 loaded, the heating plate directly pressurizes the cloth. The pressure may be covered by the combined weight of the heating plate, the heat insulating base, and the exterior (a weight may be added if necessary), or the pressure may be positively provided by a positive pressure mechanism.

その他 Other problem solving means (A) is shown as specific design conditions in this pressure heating system. This is because the printing heating apparatus described in Problem Solving Means 1 is used as a pre-printing processing apparatus, the heating plate is set to any set temperature in the range of 100 ° C. to 180 ° C., and the pressure applied to the fabric is changed from 600 Pascals to 30 Pascals. Thus, the fabric is pressurized and heated. At 30 Pascals at 100 ° C., which is the weakest condition, although the heating time was approximately 60 seconds, it was possible to stretch the wrinkles, depending on the thickness of the fabric and the strength of the wrinkles. Under strong conditions of 180 ° C. and 600 Pascals, the wrinkles could be extended in about 10 seconds.

On the other hand, (F9-2) in FIG. 9 shows a set position where the inner diameter side of the eccentric cam is on, which is indicated by 22-3. Since the highest point is set slightly higher than the position of the fabric 5 on the cassette 23 loaded, the heating plate is prevented from descending by an eccentric cam at a height slightly away from the fabric surface. That is, heating to the fabric 5 is non-contact heating. This proximity distance (gap) is represented by G in the figure. Since heating and pressurization are required for the spreading of the pre-printing process, the pressurization and heating setting (F9-1) is selected. Although the same pressure heating is efficient in the heat fixing in post-processing of textile printing, there is a weak point described below, and the non-contact heating of (F9-2) is selected by using the height position switching mechanism. This is one of the ideas.

Explain the purpose and action of non-contact heating in heat fixing. When the heating plate 20 is pressurized and heated, that is, brought into contact with the printed fabric surface, it is inevitable that the surface of the heating plate is stained with printing ink. In the conventional heat press machine, the hot pressing plate 3 is open, and the surface of the hot pressing plate 3 is dealt with when the worker touches a high-temperature object, for example, wears a glove and uses a thick cleaning cloth or a special cleaning tool. Can be cleaned. It is still unacceptable for ordinary people because it is dangerous, but a skilled full-time operator would be permitted. However, in the printing heating apparatus 17 of the present invention, it is a precondition that safety is ensured so that an ordinary person can use it. For this reason, the heating plate 20 stands by in the upper part in the housing and cannot be touched by the person. It is as. Needless to say, automatic cleaning is necessary. This is a rather cumbersome design matter. This contamination on the surface of the heating plate is a major weakness of the ink fixing method by pressure heating.

Ink cloth dyeing (fixing of dye ink) is basically a heating method in a cotton cloth system, but pressure heating is frequently used to accelerate heat conduction from the heating plate 20. Here, attention was paid to the point that heating is essential but pressurization is not essential. A non-contact heating fixing method was devised using the same heating device for textile printing as that for stretching. This eliminates the need for a cleaning or automatic cleaning device by the user of the heating plate 20.

その他 Other problem solving means (B) was shown as specific design conditions in this non-contact heating method. This uses the printing heating apparatus described in Problem Solving Means 1 as a post-printing processing apparatus, sets the proximity distance between the heating plate and the fabric to any distance in the range of 1 to 5 mm, and sets the heating plate surface temperature to 170 ° C. to 200 ° C. This is a post-printing treatment method in which any temperature condition in the range of ° C. is performed, and thus the fabric is heated in a non-contact manner. If the proximity distance is set small, it is not always necessary to set the temperature to a high temperature. Conversely, if the proximity distance is set close to 5 mm, a high temperature setting and a long heating time are required. The heating time requires 30 seconds or more even at a short distance and high temperature setting. For example, fixing can be achieved in 2 to 3 minutes at a central setting of about 175 ° C. at a proximity distance of 1.5 mm. If this temperature is set at a high temperature close to 200 ° C., fixing can be performed in a short time of about 1 minute. Conversely, if the gap is set at 5 mm, it takes several minutes even at 200 ° C.

The action by the problem solving means 2 is as follows. A cassette proposed in Patent Document 2 which is a prototype of the cassette 23 of the present invention is shown in FIG. 10 (F10-1). Reference numeral 24F denotes a magnetic platen, which basically comprises a magnetic (for example, stainless steel) substrate and a cushioning heat insulating material layer thereon. A cross-sectional view of the cassette 23 composed only of the basic elements of the k sets is shown in (F10-2). The platen is not limited to a magnetic material and is made of a universal material and a flat plate having a thickness that can maintain rigidity. This flat plate is called platen 24 again. This is supported by a platen support 23 </ b> P provided in the cassette 23. The method of fastening the fabric is not limited to the use of magnets. Assuming the use of some fabric fastening methods described later, the result cassette will be slightly larger than the original model of Patent Document 2, but it is not deviating from the basic concept of downsizing the printer. Thought.

FIG. 11 shows a method for placing (setting) the fabric 5 on the cassette 23. (F11-1) is a cassette 23 having a platen 24 above. First, place the fabric 5 on the platen 24 as shown in (F11-2), and take care not to cause the placement position (up, down, left, and right) on the platen of the fabric 5 to be distorted at a desired location as shown by symbol A. While preparing. In addition, as shown by the symbol S, the wrinkles generated when the fabric is placed are gently stretched. Next, the fabric is pressed against the platen using magnetism or a frame, and set. Then, the fabric protruding from the platen as shown by (F11-3) is folded inside the cassette 23 as shown by symbol T. (F11-4) is a completed drawing of the fabric in the cassette. The user's fabric is handled only once at this time. The rest will be handling of a rigid cassette.

】 I will explain the movement of this cassette in the printer. FIG. 12 (F12-1) shows a cross-sectional view of the small inkjet textile printer 6Ss. Reference numeral 26 denotes a door of a cassette insertion slot of the printer 6Ss. Reference numeral 27 denotes a cassette table on which the cassette 23 is placed and taken in and out of the printer. Reference numeral 28 denotes the cassette conveying system. The important functional devices in the printer are a print head unit number 29 and an ink tank 30 for replenishment. Waste ink tanks are omitted. (F12-2) is a diagram in which the cassette 23 is pulled into the back of the printer 6Ss and printing is about to start.

作用 Explain the action of the “cassette” in which the object to be handled in this way is not “cloth” but “rigid”. In the case of cotton, which is a typical textile type for printing, the combination of the heating device for printing and the cassette of the problem solving means 1 for pre-processing and post-processing brings unprecedented simplicity and safety. Give me. This is shown in FIGS. First, as a pre-printing process, the door 19 of the heating apparatus body 17 for printing indicated as “Heat Fixing” in FIG. 13 is opened, and the cassette 23 is set (F13-1). The cassette 23 is inserted into the textile heating device 17 (F13-2) and pressurized and heated to spread the cocoon, and when finished, it is detached from the device (F13-3). Next, the user holds the cassette 23 and loads it into the textile printer 6Ss labeled “Printer” in FIG. 14 (F14-1) to perform printing. The cassette 23 (F14-2) sent out from the printer is taken out, and the cassette, not the fabric, is held in the hand and inserted into the textile heating apparatus body 17 again as shown in FIG. This is post-processing pressure and heat fixing, and when completed, the cassette is detached from the apparatus. The user has never touched the fabric until this final process. In addition, in setting to each device, the cassette is simply put in a predetermined place and is removed after being inserted. As in the past, there is no need to perform any fabric operations such as adjusting the position of the fabric each time, correcting the distortion, and stretching the ridges many times.

Estimate the approximate time required for fabric handling for each processing step. In the conventional method, it is assumed that it usually takes about 30 seconds to set the fabric on the heat press machine 1 for the pretreatment shown in FIG. The fabric setting for the printer of FIGS. 2 and 3 typically takes about 60 seconds. As in Patent Document 3, it takes about the same time as a pre-setting method in which it is placed on a platen (also referred to as a carriage) in some other place and fastened with a frame and the protruding part is folded into the lower part of the platen. The subsequent post-processing steps of FIGS. 4 and 5 are assumed to take about 60 seconds. Assume that about 30 seconds of cleaning the heating plate is added. A total of 180 seconds. On the other hand, in the cassette recycle method of the present invention, as shown in FIG. 11, the setting of the fabric to the cassette is performed for the first time in a place different from the printer, but first the same time as the above-described setting method of the printer to the platen is required. It is. About 60 seconds. Thereafter, neither the pre-processing step (FIG. 13), the loading into the printer (FIG. 14) nor the post-processing step (FIG. 15) takes time to handle the fabric. However, the post-treatment process takes about 60 seconds more time than the conventional method of pressure heating. Taking this into account, it is convenient for 120 seconds. Furthermore, unlike the heat press machine, the heating plate constituting the present invention is hidden in the heating apparatus body for textile printing and is not open. Therefore, the cooling time until the user touches after each heating step is longer than that of an open heat press. About 30 seconds is twice. The total is 180 seconds, which is the same level as the heat press system. This time comparison is not necessarily elaborate. It is shown as an example for easy understanding, and in reality, it cannot be said unconditionally by proficiency level. However, it is considered that the cassette method is not significantly longer than the conventional method.

The action by the problem solving means 3 is as follows. First of all, the size of the printing heating device 17 is simpler and lighter and smaller than a general multi-purpose heat press machine by limiting the purpose of use to stretching and dyeing. Further reduction in size has been achieved by limiting the size of objects to be handled. For example, when heating to A4 size (21 cm × 29.7 cm), it is possible to design at most 35 cm in width and 45 cm in depth at most. The size is smaller than, for example, 40 cm × 50 cm of a micro heat press machine. Since the pressurizing force is only stretched, it is lower than the conventional multi-purpose heat press machine, so that the weight of the apparatus can be 10 kg or less. The heat press is made extremely rugged and exceeds at least 20 kg. In this way, the textile heating device 17 can be made a very small and lightweight device as compared with a conventional heat press.

The floor area of the small textile printer 6Ss of the present plan is the width first, but is shown as W in (F14-1) of FIG. Assuming that the size of the object to be handled is A4, this W is the width of the cassette 23 with a short side width of 21 cm + 2 cm wide on each side, 25 cm wide, and the home position (HP) width of the print head (1 cm x 4 + 4 colors) When the frame width 2 cm =) 6 cm and the HP opposite side (HP width 6 cm−2 cm =) 4 cm are added, and the distance from the exterior is 2 cm × 2 = 4 cm, these are added to 39 cm. Here, the meaning of “HP opposite side (HP width 6 cm−2 cm =) 4 cm” is as follows. Since the position of the print head on the opposite side of the HP only needs to exceed the printing area, the opposite side of the HP of the cassette width “at most 2 cm on one side” need not be included in the calculation. (The HP side must not overlap because the cassette interferes with the recovery system under HP (not shown)). Next, the depth of the printing printer 6SsA is D in (F14-1) of FIG. 14, but the length of the cassette 23 (29.7 cm + upper side + 2 cm≈) is 34 cm, and the print head depth is about 10 cm and the distance to the exterior. 2 cm × 2 = 4 cm is added and it is 50 cm or less. Even if other additional functions are added, it is at most 60 cm.

In the conventional textile printing apparatus, the medium-sized textile printer 6Ms and the heat press machine that is not small and heavy can only be used side by side. However, in this proposal, not only the small textile printer 6Ss but also the textile heating device 17 is small and lightweight. However, both are arranged vertically as shown in FIG. The textile printing apparatus thus arranged has a width of about 40 cm and a depth of about 60 cm, which is the size of the textile printer 6Ss. This can be installed at a clothing store in the city. This top-down arrangement is possible because a new and very suitable printing heating device was obtained and combined.

The first point is that the printing heating device of the present invention has achieved safety that the user does not touch the exposed heating plate in the pre-treatment process and post-treatment process of the fabric. This is not only the effect in the pre-treatment and post-treatment steps of the fabric. The non-contact heating method used in the post-treatment process eliminates the need to clean the hot plate surface and eliminates the need for a user to clean the hot plate surface. It is. The second point is that, by combining the fabric placing cassette with the textile heating device of the present invention, the fabric is not touched at all in all heating steps, and a heating device that is extremely easy to handle can be realized.

The third point is that if the fabric is first set in the cassette by the cassette in which the fabric of the present invention is placed on the flat plate (platen) on the upper surface and the printing method that uses this in all the processes, It is freed from the difficulty of handling "undefined fabrics" directly and taking various precautions, and handling "rigid cassettes" makes it easy for anyone to handle, and the work time it brings This is the realization of a shortened printing method.

The fourth point is based on the downsizing of textile printers, but in addition to this, the function of the heating device for printing is simplified and the size and weight are reduced, which allows the printing printer and the heating device for printing to be moved up and down. This is an effect of minimizing the floor space dedicated to installation, which is not possible.

The basic apparatus and method for carrying out the invention are as described for the explanation in the item of action of the problem solving means described above. That is, the embodiment incorporating the basic components of the heating device for textile printing is shown in FIGS. The textile printing method of the present invention is as described with reference to FIGS. Although it is repeated, the cassette 23 in which the cassette described in Patent Document 3 shown in FIG. Then, as shown in FIGS. 13 to 15, a cloth that is placed in a place to receive the cassette of each apparatus throughout the pre-printing process, the printing process, and the post-printing process, and when the process is finished, the fabric is taken up and proceeds to the next process. It is a simple printing method that makes you unaware of what you are dealing with. In Patent Document 2, the main purpose of the invention of the cassette is to minimize the size of the fabric feed, particularly the width, in the IJ printing printer, and not to unintentionally increase the width of the printer in combination with the arrangement of the replenishment ink tank. That is. As a result, it is easy to handle. However, there is no particular suggestion that this cassette be used for pre-printing and post-processing. In the present invention, this cassette is actively used throughout the entire printing process to realize unprecedented handling ease.

The most representative printing method of the present invention is based on the basic concept of Patent Document 2, the print size is limited to A4 or A3, and the fabric type is cotton, rayon, hemp and a blended product containing about 50% or more of these. Limited. Furthermore, color products are limited to these light-colored grounds, and black, blue, and other colors are designated as “accepted prints”, and the print data is entrusted to printing on a general-purpose printer in the backyard.

As shown in FIGS. 8 and 9, the printing heating apparatus has a heating plate standby position and a pressure heating position when the long diameter portion, the short diameter portion, and the medium diameter portion of the eccentric cam 22 are in contact with the end portion of the heat insulating base 21. The proximity heating position is switched. G represents the gap distance between the fabric 5 and the heating plate 20 at the time of proximity heating. In place of the eccentric cam, a stopper mechanism that determines two lowering positions (pressurizing heating position and proximity heating position) of the heating plate 20 is provided, and it is also an option to selectively put in and out according to the process contents. .

Regarding the cassette, another embodiment based on the basic concept of the cassette described in Patent Document 2 will be described. First, FIG. 16 (F16-1) shows a configuration in which the relationship between the magnetic substrate of the cloth placement platen and the magnet in the cassette described in Patent Document 2 is reversed, as type 1 by cassette. That is, a universal non-magnetic platen 24 is used instead of the magnetic platen 24F, and the fixed magnet 32 is embedded or pasted in a place where the fabric is to be fastened. On the contrary, a magnetic cassette side plate 33 is used instead of the magnet 25 of Patent Document 2 that holds the fabric, and this is pulled by the fixed magnet to sandwich the fabric. It can be said that the structure belongs to the category of Patent Document 2 in the sense that magnetism is used to fasten the fabric. And the side plate 33 of 31 of this another type cassette 1 has an open / close structure. In addition, the side plate 33 is provided with push-in fins indicated by numeral 34.

布 Place fabric 5 on this platen. This is shown in (F16-2) of FIG. At this time, the fabric must be placed with care so as not to be distorted correctly at the desired position and to prevent large wrinkles. In the textile printing method of the present invention, this is the only step that must be carefully handled with regard to the handling of the fabric. Then, as shown in (F16-3) of FIG. 16, the end of the fabric that protrudes and hangs down from the platen is inserted into the inside of the magnetic cassette side plate 33 in an open state. This is indicated by the symbol T. Next, as indicated by symbol R, the magnetic cassette side plate 33 is raised. At this time, the cloth in which the push-in fins 34 provided on the magnetic cassette side plate 33 hang down is pushed into the cassette. Then, the magnetic cassette side plate 33 is attracted to the fixed magnet 32 attached to the platen to clamp and fix the fabric. This is (F16-4) in FIG.

Another type cassette No. 2 uses the conventional method of fixing the fabric to the platen with a frame, and is 35 of (F17-1) in FIG. The fabric is placed on the platen 24 of this cassette (F17-2). The same care as in the previous section is required for placing the fabric here. Next, as shown by (F17-3), the presser frame 36 is fitted onto the end of the platen 24 from above the fabric, and the fabric is fixed to the platen. Then, the fabric protruding from the platen 24 is pushed into the cassette 35 with a fingertip or the like. It is represented by the symbol T. (F17-4) is a completed drawing of the cloth placed on the cassette 35. FIG.

A specific example of switching the heating plate height position of the printing heating apparatus is shown in FIG. A connecting gear 37 is provided on the rotating shaft of another type of door 19b of the textile heating apparatus. When this door is opened, as shown in FIG. (F18-1), the eccentric cam is designed so that the longer diameter side comes to the upper side by the rotation of the connecting gear. This is indicated by the number 22-2. The cam diameter was 20 mm, and the center position was 5 mm from the lowest end of the cam. That is, the lower end position of the heating plate that is in contact with and supported by the long diameter side of the eccentric cam is 15 mm from the cam center. Here, the cam center position is designed so that the fabric height on the cassette 23 is 7.5 mm from the cam center position. Accordingly, the gap between the lower surface of the heating plate and the fabric at this time is (15−7.5 =) 7.5 mm. This is the height of the standby position of the heating plate. Next, when the door 19b is closed as indicated by an arrow 38, the connecting gear is rotated by the rotation around the rotation axis, and the cam is rotated 90 degrees as shown in the figure (F18-2). I come to. This is indicated by the number 22-3. At this time, the highest point of the cam is 10 mm from the cam rotation center position. The lower surface position of the heating plate 20 supported here is also 10 mm, and the fabric position of 7.5 mm is a gap of 2.5 mm. The symbol G indicates this gap. This is the proximity heating position, which is the proximity distance G.

Next, as shown by the arrow 39 in the figure (F18-3), the door 19b is closed, opened, and closed again. When opening here, for example, it is done while pulling a knob (not shown) provided on the door handle. This prevents the rotation of the door from being transmitted to the gear. The rotation of the rotation around the rotation axis causes the connecting gear to rotate greatly, and the cam is rotated 180 degrees as shown in the figure (F18-3) to bring the minor axis side of the cam upward (number 22-1). This cam upper point is 5 mm from the cam rotation center position. If there is no lower surface position of the heating plate 20 supported here, it will descend to this point, but since the cloth position on the way is 7.5 mm from the rotation center of the cam, it is blocked by this, and a load is applied to the cloth. Will be added. This is the pressure heating position. If a plastic heater is used for the heating plate, a load of 260 to 300 Pascals with a weight of approximately 1.7 to 2 kg is obtained for an A4 size. If the pressure heat treatment time is shortened, a weight may be added. If it is an iron plate heater, it is 2 to 3 times this, and its own weight will be sufficient as the applied pressure.

Another embodiment of the heating apparatus for textile printing is shown in FIG. (F19-1) is the printing heating device 17 as seen from the front. (F19-2) is a cross-sectional view. Here, a frame-type lever 40 having a number 43 as a rotation fulcrum is provided. Reference numeral 41 shown in (F19-1) denotes a beam of the frame-type lever, which is provided with a vertical movement point 42 for transmitting the vertical movement of the frame-type lever 40 to the heating plate 20. (F19-2) illustrates the hot plate standby state before the start of the processing operation. (F19-3) shows that the frame lever 40 is pushed down to the lowest level, and the heating plate shows that the fabric 5 on the upper surface of the cassette is pressurized and heated. (F19-4) is where the frame-type lever 40 is pushed down to a position where the heating plate reaches the proximity heating processing height, and the distance between the heating plate and the fabric 5 on the upper surface of the cassette passes through a predetermined gap represented by G in the figure. Confronted. The height positions of these frame-type levers are held at selected stopper positions with respect to each not shown. The stand-by position of the heating plate, the pressure heating position, the proximity heating position, and the pressure applied to the fabric are design items, and other methods and configurations are not limited to the above-described mechanism.

We have shown examples that embody "ease of use and safety that anyone can handle". In addition to this, it is another object of the present invention to realize downsizing of the printing apparatus and further minimize the total installation area of the apparatus. The embodiment is shown in FIG. A desktop small textile printer 6Ss and a textile heating device 25 are arranged one above the other. Both are footprints that are slightly larger than the cassettes, but instead of arranging them side by side, they are arranged vertically to take advantage of the small footprint. The clothing store is full of merchandise and is not allowed to occupy a useless area. The products are also placed vertically up to the ceiling. Since the height may be higher than the desire for the beauty of a flat low design in the office, it is more important to realize the minimum floor space for installation. In FIG. 20, the T-shirts that have been created horizontally are schematically arranged as a reference for size. Here, the fact that “the installation area is wide because it is horizontally arranged, so that it is placed one on top of the other” may be conceived by everyone, but in conjunction with the printing printer that makes up the device, the printing heating device is small and lightweight. This is a textile printing device that can only be realized once it has been realized and is combined with these preconditions.

The textile printing method of the present invention in which the fabric is made into a cassette / rigid and this cassette is used for the movement and setting of the printing process, its pre-processing and post-processing, is used in the small printing machine (A3 size or A4) of the present invention. (Size) is not limited. It can also be used in medium-sized or large-sized printing machines of conventional A3 size, A2 size or larger. In addition, explanations have been made on printing on cotton cloth (including hemp and rayon), which has a lot of needs at stores and kindergartens, but printing equipment, its pre-processing equipment and post-processing equipment are also required for other types of cloth. By adopting a cassette receiving structure, a new and unique effect of the cassette system can be enjoyed. In addition, the heating device for printing, which covers the heating source with the exterior and has a variable heating plate height and is combined with the cassette, is a safe and easy-to-use device, although its range of use is limited. It will also be used for seeds and, for example, as a device for adhering ornaments to fabrics and spreading wings.
