Abstract
Description
Mask printing method, false raw material lamination device
[0001] The present invention relates to a device for laminating edible raw materials by printing on the upper surface of a provided fabric to produce a film-type edible product, and more specifically, to a device for laminating edible raw materials by a mask printing method, which can produce products of various configurations by additionally laminating a printed layer on a previously printed raw material printing layer.
[0002] Film-type edible products are made by mixing various food ingredients and molding them into a thin film, sized to fit in the mouth. When placed on the tongue, for example, the film-type edible product gradually melts, allowing the substances inside to be absorbed into the body.
[0003] These film-type edible products come in a variety of forms, depending on their intended purpose. Examples include those for breath freshening, dental hygiene, and post-meal mouthwash. Because film-type edible products take the form of thin films, they are susceptible to moisture, and are therefore typically packaged individually in sealed packages.
[0004] As a manufacturing device for manufacturing a film-type edible product, domestic patent registration No. 10-1214140 (Method and device for manufacturing edible film product) has been disclosed.
[0005] However, the disclosed manufacturing device first produces the edible film in a wide sheet form and then cuts it, producing it using a pick-and-place method. Therefore, it has the disadvantage of not being able to produce various shapes. In other words, it can only produce simple rectangular shapes.
[0006] In addition, since the coating of raw materials is done at once, when loading a small amount of raw materials, the loss of available raw materials is large compared to the input amount, and products with a laminated structure cannot be produced.
[0007] Manufacturing equipment employing the printed mask printing method is also being used. However, conventional printed mask manufacturing equipment has difficulties in printing products with wide openings in printed patterns. In addition, since raw materials are poured onto the printed mask and printed simultaneously, the exposure time of the paste-like material on the printed mask is long, making it vulnerable to contamination. Furthermore, there are problems such as difficulty in producing products with consistent quality due to changes in the viscosity of the raw material, and high raw material loss.
[0008] In addition, although roll-to-roll manufacturing equipment is advantageous for mass production, it has the disadvantage of being limited in continuous coating while maintaining a constant pattern pitch due to the square frame size of the printing mask, and the printed pattern touches the roll or other equipment.
[0009] The purpose of the present invention is to provide a mask printing method fabrication raw material lamination device capable of producing fabrication products of various shapes having a laminated structure through a printing method using a printing mask.
[0010] As a technical solution for achieving the above object, the present invention provides a mask printing method edible raw material laminating device, which passes a fabric on which a base printed matter made of edible raw materials is printed, and additionally prints a laminated printed matter made of edible raw materials on the base printed matter, the device including: a support structure providing support; a fabric guide means mounted in the support structure and guiding the transport of the fabric; a fabric support portion installed below a fabric transport path and supporting the fabric when printing a laminated printed matter on the base printed matter; a printing mask installed on an upper portion of the fabric support portion so as to be positionally adjustable and having a plurality of printing holes formed therein through which edible raw materials to be laminated on the base printed matter pass; a mask position adjusting portion for adjusting the position of the printing mask; and a printing unit for injecting edible raw materials onto the upper portion of the position-adjusted printing mask and then spreading them out so that the edible raw materials pass through the printing holes and are laminated on the base printed matter.
[0011] In addition, the above printed matter is arranged in multiple pieces at regular intervals on the upper surface of the fabric, and the printing holes of the printing mask correspond one-to-one to the printed matter.
[0012] In addition, the mask position adjustment unit is provided with a mask support frame that is horizontally fixed to the upper part of the fabric support unit and accommodates a printing mask therein, which aligns a printing hole on a printed material, an X driving unit that moves the printing mask in a direction parallel to the transport direction of the fabric while being supported by the mask support frame, a Y driving unit that is installed on the mask support frame and positions the printing mask in a direction orthogonal to the transport direction of the fabric, and a Z driving unit that is supported on the mask support frame and elevates the printing mask.
[0013] And, the X-drive unit includes a first lead screw installed horizontally in a direction parallel to the direction of transport of the fabric, an X motor that rotates the first lead screw, and a connecting body that is coupled to the first lead screw and performs a linear reciprocating motion when the first lead screw rotates along its axis and is coupled to a printing mask.
[0014] In addition, the Y-drive unit includes a second lead screw installed horizontally in a direction perpendicular to the direction of transport of the fabric, a Y motor that rotates the second lead screw, and a second nut block that is coupled to the second lead screw and performs a linear reciprocating motion when the second lead screw rotates along its axis and is connected to a printing mask.
[0015] In addition, the printing unit includes a printing head having a raw material discharge unit that supplies edible raw material to the upper part of a printing mask, a squeegee that spreads the supplied edible raw material on a mask plate, a squeegee lifting means that raises and lowers the squeegee, and a head driving unit that reciprocates the printing head to cause the squeegee to spread the edible raw material on the mask plate.
[0016] In addition, the head driving unit includes a head transport rail extending in a direction perpendicular to the direction of transport of the fabric, a slider slidably mounted on the head transport rail, and a supporter fixed to the slider and supporting the printing head, and the printing unit further includes an elevation support plate supported by the supporter so as to be elevated, and a support plate elevation unit for adjusting the height of the elevation support plate, and the squeegee is two squeegees spaced apart in parallel with each other below the elevation support plate with a raw material discharge unit interposed therebetween, and the squeegee elevation means is a squeegee cylinder that independently elevates each squeegee.
[0017] In addition, the raw material discharge unit is a slit die having a bank, which is a space for temporarily receiving raw materials supplied from the outside, and one or more discharge slits for discharging raw materials in the bank downward onto a printing mask.
[0018] The mask printing method fabrication raw material lamination device of the present invention, which is performed as described above, can produce fabrication products of various shapes having a laminated structure through a printing method using a printing mask.

[0031] Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the attached drawings.
[0032] FIG. 1 is a drawing illustrating, for reference, an edible product (100) laminated by a edible raw material laminating device according to one embodiment of the present invention.
[0033] The illustrated edible product (100) is manufactured by printing edible raw materials using a screen printing method. That is, edible raw materials in paste form are injected into a printing mask (25) having a plurality of printing holes (25c in FIG. 8) formed therein, and then manufactured using a screen printing method. Naturally, the shape of the edible product (100) reflects the shape of the printing holes (25c) of the printing mask. The edible raw materials themselves are general.
[0034] In this way, since the edible product (100) is manufactured by a printing method using a printing mask (25), the shape of the product body (100) varies depending on the shape of the printing hole (25c). By manufacturing the shape of the printing hole (25c) in various ways, edible products (100) of various shapes can be manufactured. For reference, a conventional edible product manufacturing device has a structure that first spreads out an edible raw material into a wide sheet shape and then cuts the spread out sheet into a number of straight lines that are orthogonal to each other. Conventional edible products cannot help but take on a simple rectangular shape.
[0035] In particular, as shown in an enlarged view in Fig. 1, the edible product (100) has a laminated structure. That is, it has a laminated structure of a base printed matter (100a) and a laminated printed matter (100b). The base printed matter (100a) has already been formed in separate equipment (not shown).
[0036] Ultimately, the edible material laminating device (10) of the present embodiment is a device that additionally laminates a laminated printed material (100b) on top of a previously printed material (100a) already printed on a fabric. In order to accurately place the laminated printed material (100b) on top of the previously printed material (100a), a mask position adjusting unit described below is applied, which will be described later.
[0037] There are many effects that can be obtained by applying this layering method, but the most representative ones are that it is possible to produce decorative products of various thicknesses and that different types of decorative products can be integrated into one product.
[0038] For example, thick-type edible products that cannot be produced in a single print can be produced using the laminating device of the present embodiment, and different types of edible products can be produced in the form of a single film. The printed materials of each layer constituting the edible product (100) are laminated using edible raw materials having different nutritional components.
[0039] In addition, in Fig. 1, the edible product (100) has a two-layer laminated structure, but the number of layers of the edible product can be manufactured to be more than that, that is, three or more layers.
[0040] Drawing reference numeral 103 in Fig. 1 represents packaging material. The edible product (100) is sealed and contained in the packaging material (103). The user can tear the packaging material (103) to consume the product.
[0041] FIGS. 2A to 2E are cross-sectional views illustrating a laminated structure of an edible product laminated by a edible raw material laminating device according to one embodiment of the present invention.
[0042] The thickness, shape, or size of the laminated printed material (100b) laminated on the base printed material (100a) varies depending on the shape of the printing mask (25) included in the laminating device (10). Naturally, the thicker the mask plate (25b) of the printing mask (25), the thicker the laminated printed material (100b).
[0043] The edible product (100) of Fig. 2a is a type in which the thickness and width of the base printed material (100a) and the laminated printed material (100b) are the same. In contrast, the width of the laminated printed material (100b) of the edible product (100) of Fig. 2b is narrower than that of the base printed material (100a). The base printed material (100a) can be observed from above. In the case of Fig. 2c, the width of the laminated printed material (100b) is wider than that of the base printed material (100a). The laminated printed material (100b) completely covers the base printed material (100a). And, in the edible product (100) illustrated in FIG. 2d, the thickness of the laminated printed material (100b) is thinner than that of the base printed material (100a), and in the edible product (100) illustrated in FIG. 2e, the laminated printed material (100b) is thicker than that of the base printed material (100a).
[0044] The fact that various designs of the fake product are possible in this way is possible by applying the laminating device (10) of the present embodiment.
[0045] FIG. 3 is a perspective view of a mask printing method edible material laminating device according to an embodiment of the present invention, FIG. 4 is a front view showing the internal structure of the laminating device shown in FIG. 3, and FIG. 5 is a drawing showing a fabric support portion of the laminating printer shown in FIG. 3. In addition, FIG. 6 is a drawing for explaining the relative arrangement configuration of rollers inside the laminating printer of FIG. 3, and FIG. 7 is a drawing showing the printing unit and the fabric support portion of the laminating printer of FIG. 3 separately. In addition, FIGS. 8 and 9 are drawings for explaining a method of adjusting the position of the printing mask shown in FIG. 7, and FIG. 10 is a drawing showing the printing mask and the printing head of FIG. 7 separately. In addition, FIG. 11 is a side view of the printing head of FIG. 10, FIG. 12 is an exploded perspective view of the slit die shown in FIG. 11, and FIGS. 13a and 13b are drawings for explaining the operation of the printing head of FIG. 12.
[0046] As shown, the mask printing method edible material laminating device (10) according to the present embodiment has a basic configuration of a laminating printer (20) and a heating and curing device (50).
[0047] The laminated printing machine (20) additionally coats a laminated printed material (100b) on the upper surface of the printed material (100a) that is already printed on the fabric (13), and the heating dryer (50) heats and dries the printed edible material.
[0048] The laminating device (10) passes a fabric (13) on which a printed material (100a) is printed, and additionally prints a laminated printed material (100b) on top of the printed material (100a). The edible raw material of the laminated printed material (100b) may be the same as or different from the edible raw material of the printed material (100a).
[0049] This layering device (10) comprises a support structure (21), a fabric guide means, a fabric support part (24), a printing mask (25), a mask position adjustment part, and a printing unit (30).
[0050] The support structure (21) is a fixed frame erected on the ground. The fabric (13) supplied from the outside passes through the interior of the support structure (21). As illustrated in Fig. 3, a printed material (100a) is printed on the upper surface of the entering fabric (13).
[0051] The base printed matter (100a) is arranged in multiple pieces at regular intervals on the upper surface of the fabric. In this embodiment, the base printed matter (100a) and the laminated printed matter (100b) are illustrated as simple squares, but the shapes of the base printed matter (100a) and the laminated printed matter (100b) may vary.
[0052] The fabric guide means is installed within the support structure and guides the transport of the fabric (13) passing through the support structure (21). The fabric guide means includes a guide roll (21a), a horizontal maintenance roll (21c), a suction roll (22), and two press rollers (55). Among the two press rollers (55), the press roller (55) on the right side in the drawing of Fig. 5 is accommodated in the cabinet (51) of the heating dryer (50).
[0053] The press roller (55) located on the left side of the drawing in Fig. 4 guides the movement of the fabric (13) toward the guide roller (21a). In addition, the press roller (55) installed on the right side presses down the fabric (13) that has passed through the heater (53) and guides it to the subsequent equipment. The structures of the press rollers (55) on both sides are identical.
[0054] The pressing roller (55) located on the left side of the drawing of Fig. 4 is a roller that downwardly supports the fabric (13). The reason why the pressing roller (55) is applied instead of a flat roller (a roller without unevenness on the outer surface) is because the printed material (100a) is located on the fabric (13). If a flat roller is used, the printed material (100a) is damaged by being pressed by the pressure of the flat roller.
[0055] On the outer surface of the press roller (55), a passage groove (55a) and a press ring portion (55b) are formed. The passage groove (55a) is a groove of a certain width and depth formed along the circumferential direction of the press roller (55). The printed matter (100a) printed on the fabric (13) passes through the passage groove (55a). Since the passage groove (55a) is formed in the press roller (55), there is no concern that the printed matter (100a) will be pressed and damaged even if the fabric (13) being transported passes through the lower part of the press roller (55). The press ring portion (55b) is a protrusion of a certain width extending along the circumferential direction of the press roller (55), and contacts the fabric (13) between the printed matter (100a) to keep the fabric taut.
[0056] The guide roller (21a) is a flat roller that guides the fabric (13) that has passed through the one-sided pressing roller (55) toward the horizontal maintenance roll (21c). Since the guide roller (21a) is in contact with the bottom surface of the fabric (13), there is no concern about damaging the printed material (100a).
[0057] The horizontal maintenance roll (21c) serves to keep the fabric (13) horizontal between the fabric support (24) and the printing mask (25). Two horizontal maintenance rolls (21c) form a set, and are installed on opposite sides of the fabric support (24) with the suction horizontal plate (24c) interposed therebetween and are symmetrical. The fabric (13) supported on the horizontal maintenance roll (21c) is kept horizontal and parallel to the upper surface of the suction horizontal plate (24c).
[0058] The suction roll (22) transports the bottom surface of the printed fabric (13) between the fabric support (24) and the printing mask (25) while sucking it. The suction roll (22) is installed at a lower height than the horizontal maintenance roll (21c). That is, it is located at a lower point than the horizontal maintenance roll (21c) with respect to the ground.
[0059] Meanwhile, the fabric support part (24) is installed below the transport path of the fabric (13) and supports the fabric to prevent it from sagging downward when printing a laminated printed material (100b) on the base printed material (100a).
[0060] The fabric support part (24) is provided with a support frame (24a), an adsorption horizontal plate (24c), a vertical bar (24f), and an adsorption plate cylinder (24b).
[0061] The support frame (24a) has a rectangular shape and is horizontally fixed to the inside of the support structure (21). The support frame (24a) supports a vertical bar (24f) so that it can be raised and lowered. The vertical bar (24f) is a vertically extended circular bar supported by the support frame (24a). The suction horizontal plate (24c) is fixed to the upper end of the vertical bar (24f).
[0062] The suction horizontal plate (24c) is a rectangular horizontal plate that can be raised and lowered from the upper portion of the support frame (24a). Inside the suction horizontal plate (24c), a negative pressure space (24g) is provided, as illustrated in Fig. 7. The negative pressure space (24g) is a space connected to an external vacuum pump (not illustrated) and is opened upward through a number of suction holes (24d).
[0063] When the internal pressure of the negative pressure space (24g) is lowered through the vacuum pump, the air above the suction horizontal plate (24c) is sucked into the suction horizontal plate (24c). When the vacuum pump (41) is operated while the suction horizontal plate (24c) is raised and pressed against the lower surface of the fabric (13), the fabric (13) is fixed to the upper surface of the suction horizontal plate (24c) by the action of the negative pressure. When the vacuum pump is stopped, the suction is released.
[0064] The suction plate cylinder (24b) is an element that moves the suction horizontal plate (24c) upward and downward. Through the suction plate cylinder (24b), the suction horizontal plate (24c) is raised or lowered within a certain stroke range.
[0065] The printing mask (25) is a member that is installed vertically above the fabric support member (24) so that its position can be adjusted. The printing mask (25) is formed with a number of printing holes (25c) through which a decorative material to be laminated on the printed material (100a) passes. The printing holes (25c) correspond one-to-one to the printed material (100a).
[0066] The printing mask (25) adheres closely to the upper surface of the fabric during printing and, as illustrated in Fig. 8, has a number of printing holes (25c) through which edible raw materials pass. This printing mask has a mask plate (25b) having a certain thickness and a side wall (25a).
[0067] The bottom surface of the mask plate (25b) is horizontal and can be in close contact with the upper surface of the fabric (13) as illustrated in Fig. 13a. The thickness of the mask plate (25b) may vary. The thickness of the mask plate (25b) is at least thicker than the thickness of the printed material (100a). The thicker the mask plate (25b), the thicker the laminated printed material (100b) becomes.
[0068] The printing hole (25c) in the printing mask (25) illustrated in Fig. 7 takes the shape of a square. As mentioned above, the printing hole (25c) corresponds one-to-one to the printed material (100a), so when the printing mask (25) is pressed against the upper surface of the fabric (13), the printed material (100a) is inserted into the printing hole (25c). In this state, when the edible raw material (Z) is introduced into the printing hole (25c), a laminated printed material (100b) is created.
[0069] The side wall (25a) is a square frame that forms an integral part around the upper surface of the mask plate (25b), and prevents the edible raw material (Z in Fig. 13) injected into the upper surface of the mask plate (25b) from flowing out to the outside of the mask plate (25b).
[0070] The mask position adjustment unit is connected to the printing mask (25) and adjusts the position of the printing mask in the X, Y, and Z directions of FIG. 8. The printing mask (25) can move three-dimensionally in the forward, backward, left, right, up, and down directions by the mask position adjustment unit. The reason why the printing mask is implemented so that its position can be adjusted is to align the printing hole (25c) with the printed material (100a). This is because stacking of the laminated printed material (100b) is possible only when the printing hole (25c) aligns with the printed material (100a).
[0071] This mask position adjustment unit includes a mask support frame (26), a load bracket (34 in FIG. 9), an X driving unit (27), a Y driving unit (28), and a Z driving unit (29).
[0072] The mask support frame (26) is a square frame-shaped member and is horizontally fixed to the upper portion of the fabric support portion. A printing mask is positioned at the lower portion of the inner area of the mask support frame (26). In addition, the mask support frame (26) has a frame cylinder (32) at the lower portion of each of the four corners. The frame cylinder (32) is fixed to the support structure (21) and adjusts the vertical position of the mask support frame (26).
[0073] In addition, a Y rail (26a in Fig. 9) is horizontally mounted on the outer surface of both ends in the X direction of the mask support frame (26). The Y rail (26a) guides the Y direction movement of the sliding connector (27f).
[0074] The load bracket (34) is a rod-shaped member with its central portion in the width direction bent at a right angle and supports the printing mask (25) while being positioned on opposite sides with the printing mask (25) in between. In addition, the load brackets (34) on both sides are fixed to the lower end of the connecting body (27c). Since the connecting body (27c) is indirectly fixed to the mask support frame (26), the load bracket (34) also remains fixed on the inside of the mask support frame (26).
[0075] The X-drive unit (27) adjusts the position of the printing mask (25) in a direction parallel to the direction of movement of the fabric while being supported by the mask support frame (26). The X-drive unit (27) includes a first lead screw (27b), an X-motor (27a), a connecting body (27c), a first nut block (27d), and a sliding connector (27f).
[0076] The first lead screw (27b) is a machine element installed horizontally in a direction parallel to the direction of transport of the fabric, and two of them are spaced apart and parallel to each other. The first lead screw (27b) rotates on its axis by the X motor (27a) and causes the first nut block (27d) to reciprocate.
[0077] The X motor (27a) is supported on a sliding connector (27f) and rotates the first lead screw (27b) clockwise or counterclockwise while maintaining a horizontal position. The sliding connector (27f) is a support member that can be positionally adjusted in the Y direction while being supported on a Y rail (26a).
[0078] The first nut block (27d) is a component that engages with the first lead screw (27b) and is fixed to the connecting body (27c). The connecting body (27c) is a member bent in the shape of an L and one end is fixed to the load bracket (34). Ultimately, the metal disk (25) moves in the X direction by the operation of the X motor (27a).
[0079] The sliding connector (27f) located on the right side of the drawing of Fig. 9 is also supported on the Y-rail (26a) and has a second Y-rail (27g) and an X-rail (27K) on the upper side. The second Y-rail (27g) is parallel to the Y-rail (26a) and supports the X-rail (27k) so that its position can be adjusted in the Y direction. The X-rail (27k) slidably supports the end of the connecting body (27c).
[0080] Finally, the X-drive unit (27) moves in the X direction of the printing mask (25) via the X motor (27a) while being supported on the mask support frame (26) so that the Y-direction position can be adjusted.
[0081] The Y-drive unit (28) is installed on the mask support frame (26) and positions the printing mask (25) in a direction perpendicular to the direction of movement of the fabric. The Y-drive unit (28) includes a second lead screw (28c), a Y motor (28a), a second nut block (28e), and a sliding connector (27f).
[0082] The second lead screw (28c) is a mechanical element installed horizontally on the inside of the mask support frame (26) and is axially rotated by a Y motor (28a). The Y motor (28a) is horizontally fixed on the inside of the mask support frame (26) and causes the second lead screw (28c) to rotate axially in both directions.
[0083] The second nut block (28e) engages with the second lead screw (28c) and is coupled to the sliding connector (27f) through the side passage (26g). The side passage (26g) is a hole through which the second nut block (28e) passes. When the Y motor (28a) is driven, the second nut block (28e) moves in the Y direction within the side passage (26g). At this time, the sliding connector (27f) connected to the nut block (28e) also moves together. Since the sliding connector (27f) is connected to the printing mask (25) through the connecting body (27c), the printing mask (25) can ultimately reciprocate in the Y direction.
[0084] In addition, the Z-drive unit (29) is indirectly supported by the mask support frame (26) and elevates the printing mask (25). The Z-drive unit (29) has a Z-cylinder (29a) fixed to both ends of the two-sided load brackets (34) and a connecting arm (29b). The connecting arm (29b) is a member that connects the Z-cylinder (29a) and the printing mask (25). The connecting arm (29b) is elevated by the operation of the Z-drive unit (29). Consequently, the printing mask (25) is elevated by the Z-drive unit (29).
[0085] Meanwhile, the printing unit (30) spreads out the edible raw material (Z) by injecting it onto the upper portion of the position-adjusted printing mask (25), so that the edible raw material passes through the printing hole (25c) and is laminated on the printed material (100a).
[0086] The above printing unit includes a printing head (33), a support plate lifting unit, and a head driving unit.
[0087] The head driving unit causes the printing head (33) to reciprocate, causing the squeegee (39) to spread the edible material on the mask plate (25b). That is, as shown in FIGS. 13a and 13b, the printing head (33) is reciprocated in the direction of arrow R or S, causing the printing head (33) to laminate the edible material on the printed material (100a).
[0088] The head drive unit includes a head transport rail (31a), a slider (31c), and a supporter (31d). The head transport rail (31a) is a straight member extending in a direction perpendicular to the transport direction of the fabric (13). Two head transport rails (31a) are spaced parallel to each other with a printing mask (25) interposed therebetween.
[0089] The slider (31c) is slidably mounted on each head transport rail (31a) and supports both ends of the supporter (31d). A squeezing motor (31b) is installed on the slider (31c). The slider (31c) reciprocates by the squeezing motor (31b). The supporter (31d) is a horizontal beam that crosses the upper part of the printing mask (25) and supports the printing head (33) with both ends fixed to the slider.
[0090] The support plate lifting unit serves to repeatedly raise and lower the lifting support plate (37), and includes a servo motor (36a), a belt (36e), a vertical screw (36g), and a nut portion (36h). A description of the support plate lifting unit will be provided later.
[0091] The printing head (33) includes a lifting support plate (37), a raw material discharge unit, a pair of squeegees (39), and a squeegee lifting means.
[0092] The lifting support plate (37) is a horizontal flat plate that is installed so as to be able to be lifted at the bottom of the supporter (31d). The lifting movement of the lifting support plate (37) is performed by the support plate lifting member. The lifting movement of the lifting support plate (37) is guided by the vertical guide rod (31e). The vertical guide rod (31e) is a vertical circular rod whose upper end is fixed to the supporter (31d).
[0093] The support plate lifting unit, which repeatedly raises and lowers the lifting support plate (37), includes a servo motor (36a), a belt (36e), a vertical screw (36g), and a nut portion (36h).
[0094] The servo motor (36a) is a rotational force generating unit installed vertically on the side of the supporter (31d) and has a drive pulley (36b) on the drive shaft. In addition, the vertical screw (36g) is a vertical rod installed to be able to rotate on the supporter (31d) and has a male screw portion (36f) on the lower side. In addition, a driven pulley (36d) is mounted on the vertical screw (36g). The driven pulley (36d) is connected to the drive pulley (36b) via a belt (36e). By driving the servo motor (36a), the vertical screw (36g) rotates on the axis.
[0095] The nut portion (36h) is fixed to the bottom surface of the lifting support plate (37) and is screw-connected with the screw portion (36f). As the vertical screw (36g) rotates, the lifting support plate (37) naturally rises and falls.
[0096] The squeegees (39) are spaced apart and parallel to each other at the lower portion of the lifting support plate (37) and have a squeegee blade (39a) at the lower portion. In addition, a squeegee lifting cylinder (38) is installed at the upper portion of each squeegee (39). The squeegee lifting cylinder (38) is a squeegee lifting means that lifts the squeegee (39) while being fixed to the lifting support plate (37).
[0097] The squeegee lifting cylinders (38) on both sides alternately lower the squeegees. For example, when the left squeegee (39) in the drawing is lowered, the right squeegee (39) is raised, and when the right squeegee (39) is lowered, the left squeegee is raised. When the squeegee (39) is lowered, the squeegee blade (39a) makes linear contact with the mask plate (25b), as illustrated in FIG. 13.
[0098] The raw material discharge unit is installed between two squeegees (39) and discharges paste-like raw material supplied from the outside onto the printing mask. In the present embodiment, the raw material discharge unit is a slit die (35). The slit die (35) is installed between two squeegees (39), and is mounted on the left squeegee (39) in the drawing of Fig. 11.
[0099] The lower part of the slit die (35) is relatively higher by a height H than the lower part of the squeegee blade (39a) of the left squeegee (39). When the squeegee blade (39a) touches the mask plate (25b), the slit die (35) is floating.
[0100] As mentioned above, when one squeegee (39) descends, the opposite squeegee (39) rises, so when the right squeegee (39) in the drawing of Fig. 11 descends, the slit die (35) rises higher than the height H.
[0101] In this way, since the slit die (35) is always floating from the mask plate (25b), the discharge of the edible raw material (Z) from the slit die (35) always proceeds smoothly.
[0102] The slit die (35) has the structure shown in Fig. 12.
[0103] As shown, the slit die (35) comprises a first die half (35e), a second die half (35a), and a closing plate (35k). The first die half (35e) and the second die half (35a) are tightly coupled to each other and allow the edible raw material to pass therethrough.
[0104] The first die halve (35e) is provided with an injection passage (35f). The injection passage (35f) passes the edible raw material (Z) supplied through the raw material supply tube (35m in Fig. 10) and guides it to the bank (35b).
[0105] The second die harp (35a) is formed with a bank (35b) and a number of discharge slits (35c). The bank (35b) is a space where the edible raw material supplied through the injection passage (35f) is collected. In addition, the discharge slits (35c) are a path through which the edible raw material inside the bank (35b) flows downward along the direction of arrow d.
[0106] The spacing between the discharge slits (35c) corresponds to the spacing of the printing holes (25c) in the printing mask (25). The edible material discharged downward through the discharge slits (35c) is applied in the form of a band of a certain width on the mask plate (25b). The closing plate (35k) serves to fix the first and second die halves (35e, 35a). The number of the discharge slits may vary. For example, there may be only one discharge slit.
[0107] The squeegee lifting means is a squeegee cylinder (38) located on the upper part of the lifting support plate (37) and independently lifting and lowering each squeegee. The squeegees (39) on both sides are lifted and lowered by the squeegee cylinder (38). The squeegee cylinder (38) alternately lowers the squeegees (39). As mentioned, when one squeegee (39) is lowered, the opposite squeegee is raised.
[0108] Figure 13a is a drawing showing the print head (33) moving in the direction of arrow R.
[0109] Referring to Fig. 13a, it can be seen that the edible raw material (Z) is discharged from the slit die (35), and the squeegee (39) following the slit die (35) is lowered to spread the edible raw material (Z) on the upper surface of the mask plate (25b). The edible raw material (Z) is pushed by the squeegee blade (39a) and enters the printing hole (25c) to be printed on the printed material (100a). The squeegee (39) leading the slit die (35) remains in an elevated state.
[0110] Also, as illustrated in Fig. 13b, the printing head (33) that has moved completely in the direction of arrow R moves in the opposite direction, that is, in the direction of arrow S, and pushes out the edible material (Z). At this time, the squeegee (39) on the right side of the drawing of the slit die (35) descends, and the squeegee (39) on the left side rises. While the printing head (33) moves in the direction of arrow S, the right squeegee blade (39a) pushes out the edible material (Z) and fills the printing hole (25c).
[0111] If printing through the above process is completed, the suction level plate (24c) is lowered, the printing mask (25) is raised, and the fabric is moved in the direction of arrow P in Fig. 6 and the printing process is repeated.
[0112] Meanwhile, the heating dryer (50) serves to dry the laminated printed material (100b) printed on the fabric that has passed through the laminated printer (20). The heating dryer (50) includes a cabinet (51), a heater (53), and a temperature sensor (54). The cabinet (51) is a case that passes the fabric (13) and accommodates the heater (53) and the temperature sensor (54).
[0113] The temperature sensor (54) detects the temperature of the fabric (13) and transmits the temperature information to a controller (not shown). The controller adjusts the heating temperature of the heater (53) to an optimal range. The heating method of the heater (53) can be implemented in various ways.
[0114] In addition, a pressing roller (55) is further installed inside the cabinet (51). The pressing roller (55) is a roller installed on the downstream side of the suction roll (22), and contacts the upper surface of the fabric that has passed through the suction roll and supports the fabric downward.
[0115] As mentioned above, a passage groove (55a) and a press ring (55b) are formed on the outer surface of the press roller (55). The passage groove (55a) is a groove of a certain width and depth formed along the circumferential direction of the press roller (55). The edible product (100) printed on the fabric (13) passes through the passage groove (55a). The press ring (55b) is a protrusion of a certain width extending along the circumferential direction of the press roller (55) and presses down on the fabric while contacting the upper surface of the fabric. Since the passage groove (55a) is formed on the press roller (55) as described above, even if the fabric (13) being transported passes through the lower part of the press roller (55), there is no concern that the edible product (100) will be pressed and damaged, and the tensile state of the fabric (13) is stably maintained.
[0116] Above, the present invention has been described in detail through specific examples, but the present invention is not limited to the above examples, and various modifications are possible by a person of ordinary skill within the scope of the technical idea of the present invention.
[0117] By laminating an additional printing layer on top of the already printed raw material printing layer, products of various configurations can be produced, making it industrially applicable.
