Description

Fabric conveying roller unit of film-type edible product manufacturing device

[0001] The present invention relates to a conveying roller unit applied to a film-type edible product manufacturing device, and more specifically, to a fabric conveying roller unit of a film-type edible product manufacturing device that stably maintains a conveying path of continuously supplied fabric and prevents lifting or damage to printed matter printed on the fabric.

[0002] Film-type edible products are made by mixing various food ingredients and molding them into a thin film, manufactured in a mouth-sized form. When applied to the tongue, for example, the film-type edible product gradually melts, allowing the substances within 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 such film-type edible products, domestic patent registration No. 10-1214140 (Method and device for manufacturing edible film products) has been disclosed.

[0005] However, the disclosed manufacturing method has the disadvantage of being slow in production and incapable of producing diverse shapes because the edible film is first manufactured into a fabric form, then cut and produced using a pick-and-place process. This means that only simple rectangular shapes can be produced. Furthermore, because the raw material is coated all at once, loading small quantities of raw material results in a significant loss of usable raw material relative to the input amount.

[0006] Manufacturing equipment employing metal mask printing is also being used. However, conventional metal mask manufacturing equipment has difficulties printing products with wide openings in printed patterns. Furthermore, since raw materials are poured onto the metal mask for printing, the exposure time of the paste-like material on the metal mask is long, making it vulnerable to contamination. Furthermore, variations in the viscosity of the raw materials make it difficult to produce products with consistent quality, and there is a high loss of raw materials.

[0007] 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 metal mask, and the printed pattern touches the roll or other equipment.

[0008] The purpose of the present invention is to provide a fabric conveying roller unit of a film-type edible product manufacturing device that enables good printing of edible raw materials and prevents peeling or damage of printed edible raw materials during conveyance of the fabric, thereby producing edible products of uniform quality.

[0009] As a technical solution for achieving the above object, the fabric conveying roller unit of the film-type decorative product manufacturing device of the present invention is installed in the decorative product manufacturing device for manufacturing a film-type decorative product by passing a fabric of a certain width continuously supplied from the outside through the fabric and printing an edible raw material on the upper surface of the fabric, and guides the conveying of the fabric, and includes a plurality of horizontal maintenance rolls for horizontally supporting the conveyed fabric; a suction roll for absorbing the lower surface of the fabric that has passed through the horizontal maintenance roll; a negative pressure providing unit for providing negative pressure to the suction roll; and a roller driving unit for rotating the suction roll so that the fabric receives the negative pressure and receives conveying force from the suction roll.

[0010] In addition, the above-described artificial product manufacturing device includes a fabric support section that supports the lower surface of the fabric during printing, and a printing section that performs printing on the upper surface of the fabric, and the horizontal maintenance roll is positioned on the opposite side of the fabric support section so that the fabric passes horizontally through the upper portion of the fabric support section.

[0011] In addition, the suction roll is installed at a lower height than the horizontal maintenance roll.

[0012] In addition, the suction roll includes: a suction drum that adheres closely to the bottom surface of the fabric and has micro-holes formed therein; an exhaust induction cap that is fixed to the side of the suction drum and is connected to the negative pressure providing unit and has an exhaust port for discharging air inside the suction drum; and a roll shaft that has one end fixed to the suction drum and the exhaust induction cap, respectively, and the other end supported so as to be axially rotatably supported by a support structure, and receives rotational force from the roller driving unit.

[0013] In addition, a pressing roller is further installed, which is located on the downstream side of the suction roll, contacts the upper surface of the fabric that has passed through the suction roll, and supports the fabric downward to maintain the tension of the fabric.

[0014] In addition, on the outer surface of the pressing roller, a pressing portion that comes into contact with the blank area of ​​the fabric where the decorative product is not printed, and a damage prevention groove formed between the pressing portion and separated from the decorative product to prevent the decorative product from being pressed and damaged are formed.

[0015] In addition, the pressing portion has a shape of a ring having a certain width and extending in the circumferential direction of the pressing roller.

[0016] In addition, the angle between the fabric between the horizontal maintenance roll and the suction roll and the fabric between the suction roll and the pressing roller is an obtuse angle.

[0017] The fabric conveying roller unit of the film-type edible product manufacturing device of the present invention, which is constructed as described above, enables good printing of edible raw materials by stably maintaining the conveying path of continuously supplied fabric, and prevents peeling or damage to the printed edible raw materials during conveying of the fabric, thereby producing edible products of uniform quality.

[0029] FIG. 1 is a drawing illustrating, for reference, a edible product (100) manufactured by a edible product manufacturing device (10 of FIG. 2) to which a fabric conveying roller unit according to one embodiment of the present invention is applied.

[0030] The illustrated edible product (100) is manufactured by printing edible raw materials, so to speak, using a screen printing method. That is, an edible raw material (hereinafter, edible raw material (Z)) in paste form is injected onto a metal mask (25) having a plurality of printing holes (25c in FIG. 9) 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 metal mask. The edible raw material itself is a general one. The edible product (100) is sealed and contained in a packaging material (103).

In addition, FIGS. 4 and 5 are drawings for explaining the operation and relative positional relationship of a fabric conveying roller unit according to an embodiment of the present invention, and FIG. 6 is a drawing showing the fabric conveying roller unit shown in FIG. 5 as seen from below, and FIG. 7 is a cut-away exploded perspective view of the suction roll of FIG. 3. In addition, FIG. 8 is a drawing showing the printing unit and the fabric support part of the product printer of FIG. 2 separated, and FIGS. 9 and 10 are perspective views for explaining a method of adjusting the position of the metal mask shown in FIG. 8, and FIG. 11 is a drawing showing the metal mask and the printing head separately. In addition, FIG. 12 is a side view of the printing head of FIG. 11.

[0032] The fabric conveying roller unit according to the present embodiment is installed in a fabric manufacturing device that continuously manufactures a film-type fabric product (100) by passing a fabric (13) of a certain width continuously supplied from the outside through the fabric and printing an edible raw material (Z) on the upper surface of the fabric, thereby guiding the conveyance of the fabric (13).

[0033] The fabric conveying roller unit includes a plurality of guide rolls (21a), two horizontal maintenance rolls (21c), a suction roll (22), a negative pressure providing unit (41), a roller driving unit (22p), and a pressing roller (55). Among the above components, the pressing roller (55) is included in a heating dryer (50), and the rest are mounted on a product printer (20).

[0034] The guide roll (21a) guides the fabric entering from the outside toward the horizontal maintenance roll (21c), and the horizontal maintenance roll (21c) serves to horizontally support the conveyed fabric (13). In addition, the suction roll (22) adsorbs the lower surface of the fabric passing through the horizontal maintenance roll, and the negative pressure providing unit (51) provides negative pressure to the suction roll. In addition, the roller driving unit (22p) rotates the suction roll around its axis so that the fabric receives the negative pressure and receives the conveying force from the suction roll, and the pressing roller (55) supports the printed fabric downward and maintains the tension of the fabric.

[0035] The fabric conveying roller unit according to this embodiment is included in the edible product manufacturing device (10) and is organically connected with other components, so the description of the conveying roller unit will be provided together with the overall description of the edible product manufacturing device (10).

[0036] As shown, the film-type edible product manufacturing device (10) has a basic configuration of a product printer (20) and a heating dryer (50).

[0037] The product printer (20) prints edible raw materials on the upper surface of the fabric (13) passing through its interior, and the heating dryer (50) heats and dries the printed material (101 in Fig. 5), i.e., the printed edible raw materials.

[0038] The product printer (20) includes a support structure (21), a fabric transfer roller unit, a fabric support unit (24), and a printing unit.

[0039] The support structure (21) is a fixed frame erected on the ground. The fabric (13) continuously supplied from the outside passes through the interior of the support structure (21).

[0040] The fabric conveying roller unit is mounted on the inside of the support structure (21) and guides the conveyance of the fabric (13) passing through the support structure (21). As described above, the fabric conveying roller unit in the present embodiment includes a plurality of guide rolls (21a), two horizontal maintenance rolls (21c), a suction roll (22), a negative pressure providing unit (41), a roller driving unit (22p), and a pressing roller (55).

[0041] As shown in FIGS. 3 and 4, the guide roll (21a) is arranged up and down and guides the fabric (13) that has entered the support structure (21) toward the horizontal maintenance roll (21c).

[0042] The horizontal maintenance roll (21c) is positioned on the opposite side with the fabric support section (24) in between, and supports the fabric (13) so that it passes horizontally through the upper part of the fabric support section (24). Two horizontal maintenance rolls (21c) form a set, and are installed on the opposite side with the suction horizontal plate (24c) of the fabric support section (24) in between, and are symmetrical. The fabric (13) supported on the horizontal maintenance roll (21c) is maintained horizontally and parallel to the upper surface of the suction horizontal plate (24c).

[0043] The suction roll (22) is installed at a lower altitude than the horizontal maintenance roll (21c) and transports the bottom surface of the printed fabric (13) while being sucked up. Installing at a lower altitude than the horizontal maintenance roll (21c) means that it is located at a point lower than the horizontal maintenance roll (21c) with respect to the ground.

[0044] The suction roll (22), as illustrated in Fig. 4, is installed at a height that is lowered by an angle θ1 compared to the rotation center axis of the right horizontal maintenance roll (21c). That is, an imaginary straight line connecting the central axis of the horizontal maintenance roll (21c) and the central axis of the suction roll (22) is inclined at an angle θ1 with respect to the horizontal line. θ1 may be 5 to 75 degrees, and preferably, 10 to 30 degrees.

[0045] In Fig. 7, a suction roll (22) is separately illustrated. As illustrated, the suction roll (22) is equipped with a suction drum (22a), an exhaust induction cap (22e), a roll shaft (22k), and a fixed disk (22m).

[0046] The suction roll (22) is connected to the negative pressure providing unit (41). The negative pressure providing unit (41) is a vacuum pump that extracts air from the space (22b) of the suction roll (22). When the negative pressure providing unit (41) extracts air, negative pressure is formed in the space (22b), and the fabric (13) (in contact with the suction drum) is absorbed onto the outer surface of the suction drum (22a). When the suction roll (22) rotates axially while the fabric is absorbed, tension is generated on the fabric (13) upstream of the suction roll (22).

[0047] The adsorption drum (22a) is a cylindrical member of a certain diameter that adheres closely to the lower surface of the fabric (13) and has a space (22b) therein. In addition, a number of micro-holes (22c) are formed in the peripheral portion of the adsorption drum (22a). The micro-holes (22c) serve as passages through which external air is sucked into the adsorption drum (22a) when the internal pressure of the space (22b) is lowered.

[0048] In addition, the exhaust induction cap (22e) is a hollow ring member that is fixed to the side of the adsorption drum (22a) and connected to the negative pressure providing unit (41) through the exhaust port (22f). The exhaust port (22f) is a hole to which the negative pressure providing unit (41) is connected. When the negative pressure providing unit is in operation, the air inside the space (22b) is discharged to the outside through the exhaust port (22f), and negative pressure is formed in the space (22b). This creates a state in which external air flows into the space (22b).

[0049] As the suction drum (22a) maintains negative pressure, the fabric (13) in contact with the outer surface of the suction drum (22a) is pressed against the outer surface of the suction drum (22a) by the negative pressure. In this state, when the suction roll (22) rotates, the rotational force of the suction roll (22) is transmitted to the fabric (13). Since the fabric (13) is absorbed by the suction roll (22), slipping or meandering during transport is prevented.

[0050] The roll shaft (22k) is a horizontal shaft whose one end is fixed to the suction drum (22a) and the exhaust induction cap (22e), and whose other end is supported so as to be axially rotatably on the support structure (21) via a fixed disk (22m). A bearing (22n) is mounted between each roll shaft (22k) and the fixed disk (22m). The roll shaft (22k) is axially rotatably supported by the bearing (22n).

[0051] In particular, one side roll shaft (22k) is connected to the roller drive unit (22p) and receives rotational force from the roller drive unit (22p) to rotate the shaft. The roller drive unit (22p) is a motor that rotates the suction roll (22) on its shaft. When the suction roll (22) rotates on its shaft by the roller drive unit (22p), the fabric that is adsorbed by the action of negative pressure receives a conveying force from the suction roll. The roller drive unit (22p) is one of a number of fabric conveying means that convey the fabric (13).

[0052] The pressing roller (55) is located on the downstream side of the suction roll (22), and contacts the upper surface of the fabric that has passed through the suction roll (22) to support the fabric downward and maintain tension. The pressing roller (55) is included in the heating dryer (50), and a description thereof will be provided later.

[0053] The fabric support unit (24) is installed below the conveying path of the fabric (13) and supports the fabric to prevent it from sagging when printing an edible raw material on the upper surface of the fabric (13). The fabric support unit (24) is equipped with a support frame (24a), a suction horizontal plate (24c), a vertical bar (24f), and a suction plate cylinder (24b).

[0054] The support frame (24a) has a square frame 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) and has a suction horizontal plate (24c) at the upper end.

[0055] 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. 8. The negative pressure space (24g) is a space connected to an external negative pressure providing unit (41) and is opened upward through a number of suction holes (24d).

[0056] When the internal pressure of the negative pressure space (24g) is lowered through the negative pressure providing unit (41), the air above the suction horizontal plate (24c) is sucked into the inside of the suction horizontal plate (24c). When the negative pressure providing unit (41) is operated while the suction horizontal plate (24c) is raised and brought into close contact with 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.

[0057] The suction plate cylinder (24b) moves the suction horizontal plate (24c) upward and downward. Through the suction plate cylinder (24b), the suction horizontal plate (24c) can be raised or lowered within a certain stroke range.

[0058] Meanwhile, the printing section includes a metal mask (25) and a printing unit (30).

[0059] The metal mask (25) is installed so as to be able to move up and down on the upper part of the fabric support (24), and is in close contact with the upper surface of the fabric (13) during printing, and has a number of printing holes (25c) through which edible raw materials pass, as shown in Fig. 9.

[0060] The metal mask (25) can be positionally adjusted in the X, Y, and Z directions above the transport path of the fabric (13). The metal mask (25) has a horizontal mask plate (25b) having a certain thickness and a side wall (25a). The bottom surface of the mask plate (25b) can be in close contact with the upper surface of the fabric (13). The thickness of the mask plate (25b) can vary. The thicker the mask plate (25b), the thicker the edible product (100) becomes.

[0061] In addition, a number of printing holes (25c) are formed in the central area of ​​the mask plate (25b). The printing holes (25c) are square through holes and are spaced at regular intervals in the X and Y directions. The side wall (25a) is a square frame integrally formed around the upper surface of the mask plate (25b), and prevents the edible raw material injected into the upper portion of the mask plate (25b) from being pushed outward from the mask plate (25b).

[0062] The mask position adjustment unit is connected to the metal mask (25) and serves to adjust the position of the metal mask. The metal mask (25) can move three-dimensionally in the forward, backward, left, right, up, and down directions by the mask position adjustment unit.

[0063] The reason why the metal mask (25) is implemented so that the position can be adjusted in the X direction is to prepare for an error in the longitudinal (transport direction) transport distance of the fabric (13). The fabric (13) is moved in steps of a certain pitch distance, but an error in the pitch distance may occur due to slipping or other causes, and the error in that case is compensated for. For example, if the input pitch distance is 50 cm, but the actual length of the moved fabric is 49 cm, the mask position control unit moves the metal mask (25) by 1 cm in the opposite direction to the fabric transport direction.

[0064] In addition, the reason why the metal mask (25) is implemented so that its position can be adjusted in the Y direction is to prepare for the case where the fabric (13) is misaligned in the width direction. For example, if the fabric is eccentric about 5 mm to the left in the width direction, the mask position adjustment part moves the metal mask (25) by 5 mm in the opposite direction.

[0065] In addition, the metal mask (25) is designed to be raised and lowered in the Z direction for printing of edible raw material (Z). The mask position adjustment unit lowers the metal mask (25) so that the bottom surface of the metal mask (25) is in close contact with the upper surface of the fabric (13), and the edible raw material (Z) is fed in to perform printing. After printing is completed, the metal mask (25) is raised again so that the fabric (13) can be transported.

[0066] This mask position adjustment unit includes a mask receiving frame (26), a load bracket (34), an X driving unit (27), a Y driving unit (28), and a Z driving unit (29).

[0067] The mask receiving frame (26) is a rectangular frame that surrounds the metal mask (25) and has a frame cylinder (32) at the bottom of the four corners. The frame cylinder (32) is fixed to the support structure (21) and adjusts the vertical position of the mask receiving frame (26).

[0068] Additionally, a Y-rail (26a in Fig. 10) is horizontally mounted on the outer surface of both ends in the X direction of the mask receiving frame (26). The Y-rail (26a) guides the Y-direction movement of the sliding connector (27f).

[0069] The load bracket (34) is a bar-shaped member with a central portion in the width direction bent at a right angle and supports the metal mask (25) horizontally while being positioned on the opposite side with the metal mask (25) in between. Each load bracket (34) is fixed to the end of a connecting bracket (27c). Since the connecting bracket (27c) is indirectly fixed to the mask receiving frame (26), the load bracket (34) also remains fixed on the inside of the mask receiving frame (26).

[0070] The X-drive unit (27) is responsible for the function of adjusting the position of the metal mask (25) in the X direction. The X-drive unit (27) includes an X-motor (27a), a lead screw (27b), a sliding connector (27f), a connecting bracket (27c), and a nut block (27d).

[0071] The X motor (27a) is supported on the sliding connector (27f) and outputs rotational force while maintaining a horizontal position. That is, it rotates the lead screw (27b) in a clockwise or counterclockwise direction. The sliding connector (27f) is supported on the Y rail (26a) and its position can be adjusted in the Y direction.

[0072] The nut block (27d) is a component that engages with the lead screw (27b) and is fixed to the connecting bracket (27c). The connecting bracket (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).

[0073] The sliding connector (27f) located on the right side of the drawing of Fig. 10 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) supports the end of the connecting bracket (27c).

[0074] Ultimately, the X-drive unit (27) itself moves in the X direction of the metal mask (25) via the X motor (27a) while being supported (with the Y-direction position adjustable) on the mask receiving frame (26).

[0075] The Y drive unit (28) plays a role in moving the metal mask (25) in the Y direction. The Y drive unit (28) is equipped with a Y motor (28a), a lead screw (28c), and a nut block (28e).

[0076] The Y motor (28a) is fixed to the inside of the mask receiving frame (26) and rotates the lead screw (28c) in both directions. A nut block (28e) is engaged with the lead screw (28c). The nut block (28e) is a member that is coupled to the lead screw (28c) and is coupled to the sliding connector (27f) through a side passage (26g). The side passage (26g) is a hole through which the nut block (28e) passes.

[0077] The nut block (28e) moves in the Y direction within the side passage (26g) when the Y motor (28a) is driven. At this time, the sliding connector (27f) connected to the nut block (28e) also moves.

[0078] 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 metal mask (25). The connecting arm (29b) is raised and lowered by the operation of the Z-drive unit (29). Consequently, the metal mask (25) is raised and lowered by the Z-drive unit (29).

[0079] As described above, the metal mask (25) can move in the forward, backward, left, right, up, and down directions by the X, Y, and Z driving units (27, 28, and 29).

[0080] Meanwhile, the printing unit (30) injects the edible raw material (Z) into the upper part of the metal mask (25), and spreads the injected edible raw material on the metal mask (as in silk screen printing) so that the edible raw material fills the printing holes (25c). The edible raw material filled in the printing holes (25c) is an edible product (100) that is dried and then packaged.

[0081] The printing unit (30) has a printing head (33) and a head driving unit.

[0082] The head driving unit causes the printing head (33) to reciprocate, thereby printing the edible product (100) on the fabric (13). This head driving unit includes a crossrail (31a), a slider (31c), and a supporter (31d).

[0083] The crossrail (31a) is a straight member extending in a direction perpendicular to the transport direction of the fabric (13). Two crossrails (31a) are spaced parallel to each other with a metal mask (25) between them.

[0084] The slider (31c) is slidably mounted on each crossrail (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).

[0085] The supporter (31d) is a horizontal beam that crosses the top of the metal mask (25) and supports the printing head (33) with both ends fixed to the slider. As shown in Fig. 12, the printing head (33) includes a lifting support plate (37), a support plate lifting section, a raw material discharge section (37), a pair of squeegees (39), and a squeegee lifting means.

[0086] The lifting support plate (37) is a horizontal flat plate installed at the bottom of the reciprocating beam (31d) so as to be able to be lifted. The lifting movement of the lifting support plate (37) is performed by a support plate lifting member. The lifting movement of the lifting support plate (37) is guided by a vertical guide rod (31e). The vertical guide rod (31e) is a vertical circular rod whose upper end is fixed to the reciprocating beam (31d).

[0087] 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 unit (36h).

[0088] 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.

[0089] 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.

[0090] 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).

[0091] The squeegee lifting cylinders (38) on both sides alternately lower the squeegees. For example, when lowering the left squeegee (39) in the drawing, the right squeegee (39) is raised, and when lowering the right squeegee (39), the left squeegee is raised. When the squeegee (39) is lowered, the squeegee blade (39a) makes direct contact with the mask plate (25b).

[0092] The raw material discharge unit is installed between two squeegees (39) and discharges the paste-like raw material supplied from the outside onto the metal 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. 12.

[0093] 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.

[0094] As mentioned above, when one squeegee (39) descends, the opposite squeegee (39) rises, so when the right squeegee (39) in the drawing of Fig. 12 descends, the slit die (35) rises higher than the height H. In this way, since the slit die (35) is always floating from the mask plate (25b), the discharge of the edible material (Z) from the slit die (35) always proceeds smoothly.

[0095] 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.

[0096] Meanwhile, the heating dryer (50) serves to dry the printed material (101) printed on the fabric through the product printer (20). The printed material (101) is an edible raw material printed on the fabric and must be dried to become an edible product (100).

[0097] The heating dryer (50) includes a cabinet (51), a heater (53), a temperature sensor (54), and a pressing roller (55). The cabinet (51) is a case through which the fabric (13) passes and accommodates the heater (53) and the temperature sensor (54).

[0098] 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 based on the received temperature information. The heating method of the heater (53) can be implemented in various ways, such as IR, NIR, MIR, Xeon lamp, Laser lamp, UV lamp, and Led lamp.

[0099] 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.

[0100] In particular, the angle between the fabric between the right horizontal maintenance roll (21c) and the suction roll (22) in the drawing of Fig. 4, and the fabric between the suction roll (22) and the press roller (55) is an obtuse angle. As the angle decreases, the probability of the printed matter (101) being lifted from the fabric increases, so it is preferable that the angle be at least greater than 90 degrees.

[0101] In addition, the angle (θ2 in FIG. 14) of the fabric (13) connecting the suction roll (22) and the pressing roller (55) with respect to the vertical line can be, for example, 30 degrees. As the above-mentioned angles (θ1, θ2) decrease, the contact area of ​​the fabric (13) with respect to the suction roll (22) increases. That is, the angle (k in FIG. 14) between the point where the fabric (13) begins to meet the suction drum (22a) and the point where it separates from the suction drum (22a) increases.

[0102] On the outer surface of the press roller (55), a damage prevention groove (55a) and a press portion (55b) are formed. The press portion (55b) is a ring-shaped protrusion that comes into contact with a blank area of ​​the fabric where the decorative product is not printed, i.e., a portion of the upper surface of the fabric that is not covered by the decorative product. The press portion (55b) has a certain width and takes the shape of a ring that extends in the circumferential direction of the press roller (55). The press portion (55b) supports the fabric (13) downward to maintain a taut state of the fabric (13).

[0103] And the damage prevention groove (55a) is formed between each pressing portion (55b) and is a groove that is spaced apart from the edible product (100) to prevent the edible product from being pressed and damaged. The damage prevention groove (55a) is formed along the circumference of the pressing roller (55) and has a certain width and depth. It goes without saying that the width of the damage prevention groove (55a) is larger than the width of the printed matter (101). In this way, since the damage prevention groove (55a) is formed in the pressing roller (55), even if the fabric (13) being transported passes under the pressing roller (55), there is no concern that the printed matter (101) will be pressed and damaged, and the tensile state of the fabric (13) is stably maintained.

[0104] Ultimately, the fabric conveying roller unit of the present embodiment, configured as described above, enables good printing of edible raw materials by stably maintaining the conveying path of continuously supplied fabric, and prevents peeling or damage to the printed edible raw materials during conveying of the fabric, thereby producing edible products of uniform quality.

[0105] 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.

[0106] It has industrial applicability by stably maintaining the transport path of continuously supplied fabric and preventing lifting or damage of printed materials on the fabric.
