Description

Description: TECHNICAL FIELD The present invention relates to a hot stamping variable pattern on a base material (hereinafter, also simply referred to as “base material”) made of a woven or non-woven fiber material or a plastic foil. A printing method and apparatus. Here, “variable pattern printing” means printing a variable pattern (characters, codes, images, etc.) according to variable data, as described later. BACKGROUND OF THE INVENTION In many industries, labels or labels or identification plates are required to mark products. Examples are textile or textile manufacturers and electrical / electronic device manufacturers. In the former case, the user is affixed to the woven material or the non-woven material with a label having information on the size and explanations on the washing, the washing temperature and the like. In the latter case, the product must be given a serial number and other variable appropriate product information. Users of such labels, identification plates, etc. have repeatedly demanded that the following two conditions be met, and currently available printing devices do not meet these requirements.
The current situation is that the two conditions cannot be met. These two conditions are the permanence of the printing and the ability to quickly change the variable data to be printed. Depending on the application, the label must be able to withstand relatively violent treatments, such as frequent laundry and chemical treatments. The same applies to identification plates that are washed with similar chemicals. Moreover, in that case, each information carrier is required to remain readable for a long period of time. Another problem is the formation of variable data on the identification carrier. For example, the identification plates carry regular serial numbers, so all identification plates are practically original and not duplicates. Also in the case of marking of textiles or fabrics, variable data may have to be printed, for example when printing batch or lot specifications, color or size data. As will be apparent to those skilled in the art, one of the efforts in the mass production of identification plates and labels is to produce the selectively marked carriers without problems and quickly. In the case of the marking of textiles or fabrics with variable data, the printing operation is currently mainly done by needle printers. Needle printers are sequentially line by line from the computer (line by line).
The supplied data operates to be transferred onto a substrate by a needle printer head using a colored or carbon ribbon. However, in the conventional needle printer, particularly clear print or imprint cannot be obtained, and in particular,
Printing with sufficiently satisfactory resistance to washing and washing cannot be obtained. Currently available pigments are relatively easy to wash off or fade under certain circumstances.
Also, this type of printing method cannot be used at all for printing labels on textile products having a relatively coarse texture. This is because the relatively liquid ink is scattered. in short,
Although this type of printing method is applicable to printing without the problem of variable data, it is performed at the expense of permanence or endurance of printing. In contrast to this method is the hot stamping printing method. According to this hot stamping printing method, a pigment pattern (hereinafter, simply referred to as “pattern” that is resistant to washing and washing, has excellent quality, and is capable of abundant use of color tone and color quality). It is also possible to transfer) to a carrier. (Here, the "pigment pattern" refers to a pattern of pigments such as characters, codes, and figures to be pressed.) However, even in the case of this hot stamp printing method, it takes time to switch data. .
In this printing method, the image to be printed is imprinted on the substrate to be printed using a type block or stereo plate. If the data is variable, the type block or stereo version must be changed each time the data changes. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a hot stamp type variable pattern printing method that guarantees the ability to automatically print a variable pattern inexpensively according to variable data and the permanence of the printed matter. A printing device is provided. According to the invention, according to the invention, a substrate to be printed, such as a woven or non-woven fibrous material or a plastic foil, and on one surface of the device facing the surface to be printed , A substrate having a layer of a pigment transferable when contact pressure is applied in a heated state, is sent together through a stamping station, and the substrate and the preheated hot stamping foil are subjected to a pressure reaction. A pressure is applied between a member (also referred to as a "pressure receiving member") and a stamping member or printer, whereby the pigment is sequentially applied as a pattern or mark of characters, codes, images, etc. on the substrate by the applied stamping force. Is transcribed to. The pattern or mark is usually a dot or character that is printed in sequence. The pigment is at the transfer temperature (the temperature at which transfer occurs), usually just below its melting point. In the stamping station, it is preferable to bring the surface of the hot stamping foil, which is not coated with the pigment, into contact with the pressure reaction member which also has the function of heating the hot stamping foil. What is important is that the hot stamping foil is preheated on its feed path just before reaching the stamping station, and the back side, which is the non-printed side of the substrate at the stamping station, is guided so as to come into contact with the pressure reaction member. is there. Optionally, the pressure reaction member can be heated. It is also desirable to heat the surface of the base material on the side in contact with the pigment so as not to cool it, thereby increasing the tackiness or adhesive force of the pattern transferred to the base material as much as possible. In the case of the conventional hot stamp printing method, the printing block is heated and pressed against the surface of the hot stamping foil, which is free of pigments, and the hot stamping foil acts as a pressure reaction member through the substrate. Although pressed, the method of the present invention is the reverse. That is, the heat required to transfer the pigment onto the substrate is introduced into the pigment layer by preheating the hot stamping foil and, if necessary, also the pressure reaction member. Therefore, the user is not constrained by the design of the printer, and instead of or in addition to the conventional stereo version, a heat-sensitive mechanism such as a needle print head or numbering machine. Can be used. Therefore, according to the present invention, all the advantages obtained by printing by hot stamping are retained, and the advantages by the needle printing method are added. A preferred device for carrying out the method of the invention is a device arranged at the stamping station on the side adjacent to the back side of the substrate, which comprises a pressure reaction member (pressure receiving member),
A print head is provided opposite the pressure reaction member, the pressure reaction member having a pressure receiving surface and forming an additional heating element placed in contact with the hot stamping foil at a stamping station. Alternatively, the hot stamping foil, with the force of the printer applied to the surface of the non-pigment side, the substrate is contacted with the pressure reaction member, the pressure reaction member is configured to heat as necessary, The preheating element can be arranged in contact with the hot stamping foil in the area leading to the stamping station. It should be emphasized here that the basically heat-sensitive printhead according to the invention has a very outstanding applicability in terms of function, considering the following points. That is,
In the case of the conventional hot stamping method, it takes about one-tenth of a second holding time to press the printing block against the hot stamping foil, while the dot base using the printer according to the present invention is used. The contact time (pressure-holding time) for applying the stamping force in the above is only on the order of 1/1000 second. EXAMPLE Referring to FIGS. 1 and 2, a substrate 10 to be printed, such as a fiber material or a plastic foil, and a conventional hot stamping foil 20 are both stamped.
Sent to the station or area 30. The stamping station 30 is defined on one side by a pressure reaction member (pressure receiving member) 40 in the form of a pressure receiving beam material or pressure receiving block, and on the other side a variable pattern forming having a needle print head or a dot forming print head. A printer (also referred to as a "variable pattern printer" or "patterning printer" or simply "printer") 50 is defined. The substrate 10 has an upper surface (front surface) 12 to be printed and a lower surface (back surface) 14. The direction of feed of substrate 10 through stamping station 30 is indicated by arrow 16. In this embodiment, the needle print head of the printer 50 is located on the lower surface 14 side of the substrate 10 and moves transverse to the feed direction 16 of the substrate 10 within a machine frame (not shown). You can move back and forth on path 52. The transfer of the substrate 10 and the hot stamping foil 20 in the area of the stamping station 30 is carried out during the printing process (hot stamping foil 20
From the substrate to the substrate 10 line by line, i.e. line by line) for a short break. On the surface of the hot stamping foil 20 that faces the upper surface 12 of the substrate 10, a conventional pigment layer 22 that can be transferred under contact pressure when sufficiently heated is provided. A stamping layer (not shown) is provided on the upper surface of the pigment layer 22 in a known manner, and a carrier foil is further provided thereon. The exposed surface 24 of the carrier foil forms the surface of the hot stamping foil 20 opposite the pigment surface 22. Hot stamping foil 20 stamping station
On the way to 30, it goes through the preheating zone. In this embodiment, the preheat zone is the surface 24 of the hot stamping foil 20.
It consists of a heated metal plate 60 in contact with. In the embodiment shown in FIG. 1, the metal plate 60 is constituted by a separate member, but the metal plate 60 may be connected to the pressure receiving member, that is, the pressure reaction member 40 in a heat transfer relationship, or a member.
It is also possible to form it integrally with 40. In this case,
There is no gap or gap between members 60 and 40. The dimensions of the metal plate or preheating element (hereinafter also simply referred to as the “heating element”) 60 transverse to the feed direction 18 of the hot stamping foil 20 are such that the pigment layer 22 moves in the movement trajectory 52 of the print head 50. The dimensions are chosen so that it can be preheated over the entire range. The length of the heating element 60 in the direction along the feed direction 18 of the hot stamping foil 20 is
Considering the temperature of 60, the length is as follows. That is, the length of the hot stamping foil 20 is such that the pigment layer 22 is the pressure receiving beam material 40.
When a stamping force is applied by the printer 50 in the form of dots or letters, the pigment is heated to such an extent that it can be neatly transferred from the hot stamping foil onto the substrate 10. Make it long enough. In addition, substrate
10 also to increase the binding strength of the pattern pigment to it,
It is preferable to heat. In order to maintain the required temperature, a thermostat type temperature controller (not shown) is provided in association with the heating element 60 and the pressure receiving member or pressure reaction member 40, and the total heating area 60 and 40 is provided. , Can be divided into different temperature zones. FIG. 2 is a side elevational view of a preferred embodiment of the hot stamping variable pattern printing apparatus shown in FIG. 1 (hereinafter also simply referred to as “hot stamping apparatus”). In FIG. 2 and other drawings, the mechanical frame, the drive mechanism, and the electric / electronic devices are omitted for clarity. Such elements are well known in the art and can be easily conceived by those familiar with the design and operation of printing machines and hot stamping devices. In FIG. 2, the feed direction 16 of the substrate 10 is from right to left. The substrate 10 is drawn from a stock reel supported by a machine frame (not shown) by a pair of transport rollers 62 ', 62 "located downstream of the stamping station 30 in the feed direction 16. Then,
A pair of conveying rollers can be additionally provided upstream of the stamping station 30 as viewed in the feeding direction 16.
Substrate 10, which is typically a fibrous material or metallized plastic foil, is introduced along the slightly curved surface of guide member 54 into contact therewith and shortly before stamping station 30. In this embodiment, the guide member 54 is heated and its temperature is regulated by a thermostat. Hot stamping foil 20 is a mechanical frame (not shown)
Is pulled out by a pair of conveying rollers 64 ', 64 "from a stock reel (not shown) supported by the conveying rollers.
After passing between 64 'and 64 ", it contacts a slightly curved surface 44 on the pressure reaction member 40 and is deflected at the front end of the surface 44 into a stamping station 30 parallel to the substrate 10 Traveling in and around the deflecting edge 42 of the pressure reaction member or beam 40 at the front end of the stamping station, and then substantially perpendicular to the feed direction 16 of the substrate 10, the surface 46 of the pressure reaction member 40. And travels to another pair of transport rollers 66 ', 66 "in a direction away from the. The roller pair 66 ', 66 "is also driven in the same manner as the other transport roller pair 64', 64". Orientation of curved surface 44 relative to the position of transport rollers 64 ', 64 "and alternative transport rollers 66', 66"
Due to the tensile force exerted by the hot stamping foil 20, the hot stamping foil 20 is held in intimate contact with the curved surface 44 up to the deflecting edge 42 and heated by the pressure reaction member 40. or,
Hot stamping foil 20 as described in connection with FIG.
Heating is also done from its exposed surface 24. As shown in FIG. 2, additional heating of the hot stamping foil 20 may be performed by radiating heat from the surface 56 of the guide member 54 to the pigment layer 22 of the hot stamping foil 20. it can. Surface 56 forms a V-shaped gap with surface 44 that tapers in the direction toward stamping station 30. As a result, the pigment layer
As the spacing between 22 and the surface 56 decreases progressively, radiant heat entering the pigment layer 22 from the surface 56 will increase until just before reaching the stamping station 30. This radiant heat quantity can be adjusted not only by changing the temperature of the guide member 54, but also by mounting it on the machine frame so that the guide member 54 can be moved generally parallel to the feed direction 16. You can Further, this adjustment of the radiant heat can be achieved by making the position of the guide member 54 relative to the machine frame adjustable so that the angle of the V-shaped gap between the surfaces 44 and 56 can be changed. it can. The hot stamping foil 20 is stretched in its feed direction 18 by being heated in the region of the pressure reaction member 40. Nevertheless, the hot stamping foil 20 is always in close contact with the pressure beam material 40 and the deflection edge
The peripheral speeds of the conveying rollers 66 ', 66 "are set so that they are guided without shaking when passing through the 42.
Set slightly higher than the peripheral speed of 4 ', 64 ". In practice, a peripheral speed difference of about 0.5% was found to be suitable. Finally, in relation to the importance of the deflecting edge 42 It should be noted that this deflecting edge 42 must be located as close as possible to the rear of the needle head of the printer 50 in the feed direction 18. In this way, the hot stamping foil 20 is This is because they are separated from the base material 10 in a direction away from the base material 10 immediately after the formation of the mark or pattern printed by the printer block 50. As a result,
At this point, the possibility of the hot stamping foil sticking to the substrate in the area of the printed marking pattern or image is avoided, even though the pigment is still soft enough to stick. The embodiment described above is advantageously used when the substrate 10 does not exceed a certain thickness and the printer block 50 used has a relatively high sensitivity to heat. The embodiment shown in FIGS. 3 and 4 essentially differs from the first embodiment described above only in the following respects. That is, the positions of the printer 50 and the pressure receiving member 40 with respect to the base material 10 and the hot stamping foil 20 are reversed. In the description of the second embodiment, the same reference numerals as in the first embodiment are used as much as possible. Therefore, it should be understood that all the matters described above also apply to the second embodiment unless otherwise stated. In the second embodiment, as shown in FIGS. 3 and 4, the substrate 10 to be printed is fed through the stamping station 30 with its back surface 14 positioned on the pressure receiving member 40. You will be guided to 16. The pressure receiving member 40 in this embodiment is schematically shown as a slab that is long in the feed direction 16. The pressure receiving member 40 can be heated and its temperature can be adjusted by a thermostat. As shown in FIG. 3, the slab-shaped pressure receiving member 40 is
Seen at 16, the downstream end of the stamping station 30 (4th
End). The hot stamping foil 20 is fed to the stamping station 30 at an angle (V), and the hot stamping foil 20 and the base material 10 meet immediately before the stamping station 30 or at the stamping station 30 for the first time. The pigment layer 22 on the hot stamping foil 20 is located facing the substrate 10, and on its way to the stamping station 30, the exposed surface 24 of the hot stamping foil 20 is brought into contact with the heating element 70. The heating element 70 is located as close as possible to the stamping station 30 to optimally heat the hot stamping foil from the stamping station 30 in a direction opposite to the feed direction 18 of the hot stamping foil 20. It extends a sufficient distance. Each heating element 70 in contact with the hot stamping foil 20 is also provided with at least one cartridge-type heater, the emission of heat from which is regulated by a thermostat. In this embodiment, the stamping station 30
Is defined by the last part of the pressure receiving member 40 as seen in the feed direction 16 and the printing block 50 facing this last part. In this embodiment, as shown in FIGS. 3 and 4, the stamping force is applied from the exposed surface 24 side of the hot stamping foil 20. For example, the stamping force applied by the needles of the needle print head forming the printer 50 is the pigment layer of the hot stamping foil 20.
Before reaching 22, the thickness of the substrate 10 to be printed and its material should be sufficient, as long as it is sufficient to penetrate the very thin carrier foil of hot stamping foil 20 and also the very thin stamping layer. It has nothing to do with obtaining a quantitatively good printed image. In other words, an excellent printed image can be obtained regardless of the thickness of the substrate 10 and its material. In order to avoid the problem that the hot stamping foil 20 and the base material 10 adhere to each other after the printing process, the hot stamping foil 20 is also stamped after printing in the embodiments shown in FIGS. 3 and 4. The direction of movement within station 30 is steeply biased. For this purpose, the feed direction
Immediately after the stamping station 30 as seen at 16, there is provided a knife-shaped beam 80 having a relatively sharp edge similar to the deflecting edge 42 of the embodiment shown in FIG. FIG. 3 shows the basic arrangement of the constituent members of the second embodiment, while FIG. 4 is a schematic side view showing the preferable arrangement of the constituent members of the second embodiment. It is shown. The base material 10 is transferred from the stock reel to the transfer rollers 62 ′ and 6
2 ″. First, the substrate 10 runs on the horizontal surface 43 of the elongated pressure-receiving member 40, and then the pressure-receiving member 40.
The stamping station 30 is passed obliquely downward along the inclined surface 41 of the. The pressure receiving member 40 can also be heated in this embodiment. A pair of transport rollers 62 'and
62 "intermittently pulls the substrate 10 through the stamping station 30. As previously mentioned, the transport of the substrate 10 is interrupted during the printing process on the substrate. When
The deflection of the substrate 10 in the direction of the traveling path at the transition portion between 41 and 41 contributes to the purpose described later and also serves to set the steady position of the substrate at the stamping station 30. Hot stamping foil coming from stock reel
20 is also passed through the stamping station 30 by two pairs of transport rollers 64 ', 64 "and 66', 66". A heating element 70 is disposed between the first pair of transport rollers 64 ', 64 "and the stamping station 30. The heating element 70 is shown on the non-pigmented side of the hot stamping foil 20 as shown. It has a curved surface 74 that contacts the exposed surface 24. The heating element 70 has a protrusion 72 at the end adjacent to the stamping station 30, whereby the hot stamping foil 20 is It is possible to receive heat until just before it reaches the stamping station 30. The printer 50 can again be in the form of a commercially available needle-dot print head, which printer 50 can The longitudinal axis is aligned so that it is perpendicular to the surface 41 of the pressure receiving member 40. The printhead needles act on the surface 24 of the hot stamping foil 20, which is free of the pigment layer. The printhead of the printer 50 is heated by arranging it obliquely to correspond to the slope of the surface 41 as shown (ie, placing the printer 50 perpendicular to the sloped surface 41). The knife beam material 80 is positioned as shown in Fig. 4 so that it faces the substrate 10 from the printer 50 towards the travel path in the area of the stamping station 30. It presents a deflection free edge that protrudes as much as possible, so that the deflection free edge of the knife beam material 80 peels the hot stamping foil 20 upwards from the substrate 10 immediately after it passes through the stamping station 30. The curved surface 74 of the heating element 70 and the shape and arrangement of the knife beam material 80, in combination with the arrangement of the associated transport rollers 64 ', 64 "and 66', 66", of the hot stamping foil 20. For Basically curved set the travel path, as a result, the stamping station 30
The hot stamping foil 20 is prevented from vibrating or agitating in the area of. It should be pointed out here that the printer 50, which moves in the machine frame in FIG. 4 perpendicular to the plane of the drawing, does not necessarily have to be the preferred needle printer. Stamping force is generated sequentially, for example, for each character,
Print heads other than needle printers can be used with equal effect. Examples of such other printers are type wheel or chain printers. The method of the present invention allows to transfer the heated pigment from a hot stamping foil to a preferably heated substrate in order to obtain a sharp printed image and a strong bond of the pigment to the substrate. Thin material (hot stamping foil 20
Both rely on a very thin carrier foil and stamping layer to transfer the stroke of the printer 50 to other materials (the substrate 10). An important advantage of the method of the present invention is that it allows printing strikes to be made 400 to 500 times faster than in printing plates of hot stamp printers. Therefore,
It is not possible to heat the hot stamping foil on impact. Therefore, as described above, it is necessary to preheat the hot stamping foil 20 to the transfer temperature at a point very close to the transfer point. The method of the present invention is suitable for printing variable data on clothes or the like, and realizes printing having the same resistance to washing and dry cleaning as the generally used hot stamping method. When performing multicolor printing, multiple stamping stations can be used and white, gold or silver printing can be performed on a black background or other dark material. In the context of the electronics industry, the device according to the invention for the first time makes it possible to perform high-quality printing on metallized adhesive plastic (for example polyester) foils used for nameplates. This print has a high resistance to gasoline, oil and cleaning liquids. Also in the case of printing on such a plastic foil, according to the present invention, it is possible to perform multicolor printing, and it is also possible to perform silver printing on a black plastic foil. Further, not only can multicolor printing be performed using a plurality of modules arranged in series, but also by reversing the substrate between two printing modules, different information can be printed on both sides of the substrate. it can.
