Description

Technical Field

[0001] The present invention relates to a hybrid inkjet printer capable of continuous output, and more particularly, to a hybrid inkjet printer capable of continuous output, wherein printing is performed while an output medium is input into an input portion and moved toward an output portion for discharge, wherein the input portion and the output portion are formed in such a manner that pressure can be applied to the surface of the output medium in accordance with the thickness of the output medium, thereby achieving continuous output and enabling the output medium to be moved stably, thereby minimizing printing defects. Background Art

[0002] In recent years, with the development of printers, it is possible to output not only paper and thin plastic paper as general output media but also various output media such as wooden boards, glass plates, and stone plates.

[0003] This technological advancement is achieved by using UV ink in printers or printers. Since UV ink has the property of being fixed to the output medium once it is sprayed on, as long as it is exposed to ultraviolet light, it can be used on any output medium.

[0004] In particular, output on a rigid plate-shaped output medium has attracted much attention compared to conventional flexible paper.

[0005] This is because existing outdoor signs, interior and exterior decoration materials, etc. rely on methods such as silk screen printing for actual output, which makes the process complicated, requires a lot of time and money, and not only that, but also reduces satisfaction with the output status.

[0006] Therefore, as the output media becomes diversified, the thickness of the output media also becomes diversified.

[0007] In response to this, a flatbed plotter has been developed for printing on a plate-shaped output medium.

[0008] However, the flatbed plotter uses vacuum suction to fix the medium. When the vacuum suction cup receives suction force and transfers the output medium, friction exists between the suction cup and the output medium, which is not preferable.

[0009] If the system is used to release the vacuum suction each time the output medium is transferred and restart the vacuum suction after the transfer, it is extremely inconvenient and will also increase the time required for output.

[0010] Therefore, the output medium needs to be fixed to a suction cup, and the inkjet head needs to be moved horizontally on a horizontal plane to output the desired image to the output medium. However, this method has the problem of making the working structure of the inkjet head complicated and the inkjet head too large, and the production cost of the printer will also increase.

[0011] Therefore, it is necessary to develop a printer having a unit that can transfer the output medium on the above-mentioned suction cup, so as to be suitable for a printer having an inkjet head that only performs linear reciprocating motion.

[0012] In view of this, a flatbed printer is proposed in Korean Patent Application No. 10-2005-0013291.

[0013] In detail, the existing general flatbed printer includes: a workbench, which has a connecting path inside and an air intake port on the upper surface; a frame, which is fixed to the above-mentioned workbench as a whole and is used to support the workbench; a driving roller and a driven roller, which are fixed to a roller bracket fixed to the above-mentioned frame as a whole and are arranged in front of or behind the above-mentioned workbench; a driving unit, which is used to apply torque to the above-mentioned driving roller; a transfer belt, which is hung on the above-mentioned transfer roller for rotation, and the lower surface passes above the above-mentioned workbench and is formed of a breathable tissue; an aspirator, which is connected to the above-mentioned connecting path and is used to inhale air from the inside of the workbench; and an inkjet head rod, which guides the inkjet head to move horizontally on the above-mentioned workbench and can be adjusted in height up and down. The above-mentioned workbench is in the form of an upper plate with multiple air intake ports and a box-shaped upper portion open, forming a connecting path on one side and forming multiple partitions at one end in a manner of forming an open path. Open and close valves are respectively provided on the open paths of the above-mentioned partitions, and the above-mentioned open and close valves include an outer cover formed in a manner of communicating with the above-mentioned connecting path.

[0014] However, the conventional general flatbed printer constructed as described above has a porous transfer belt arranged on a vacuum adsorption workbench through the above-mentioned structure, thereby being able to transfer the output medium in a state of adsorbing the output medium. Therefore, when the inkjet head needs to transfer the output medium in a fixed-form flatbed printer, the troublesome problem of releasing the vacuum adsorption state and transferring the output medium can be solved. However, since the push roller is not constructed in a manner to apply pressure corresponding to the thickness of the output medium, it can move the output medium stably, and therefore there is a disadvantage that defects may occur when printing on the output medium. Summary of the Invention

[0015] Technical issues

[0045] The above-mentioned input pressurizing unit 160 is located in front of the above-mentioned setting component 150 by being arranged at one end and the other end in a liftable manner on the input fixing plates arranged on both sides of the upper surface of the above-mentioned frame 110. It can work in response to the control of the control unit to change the pressurizing force in response to the thin or thick output medium to apply pressure to the upper surface of the output medium, so that the output medium can be stably input before entering the upper part of the above-mentioned vacuum adsorption part 125.

[0046] That is, the above-mentioned input pressurizing unit 160 includes: an input moving piece 163, one end and the other end of which are connected to the respective surfaces of the input fixed piece 161 fixedly set on both sides of the upper surface of the above-mentioned frame 110 by a pair of linear guide rails 162 as a medium, and can be moved in the up and down directions; an input setting frame 164, one end and the other end of which are fixed to the respective surfaces of the above-mentioned input moving piece 163; an input driving motor 165, fixedly set on one side of the above-mentioned input setting frame 164, including a reducer 165a, so as to be able to drive correspondingly to the control of the control unit; an input driving shaft 166, one end of which is connected to the above-mentioned reducer 165a, and the other end of which forms an input driving gear part 166a for power transmission; an input driven shaft 167, one end of which is connected to the above-mentioned reducer 165a, and the other end of which forms an input driving gear part 166a for power transmission; It is gear-engaged with the input driving gear portion 166a of the above-mentioned input driving shaft 166, and the other end passes through the above-mentioned input movable piece 163 to be rotatably arranged, forming an input driven gear portion 167a at the terminal end; the input rack portion 168 is fixedly set on each surface of the above-mentioned input fixed piece 161, and is gear-engaged with the input driven gear portion 167a of the above-mentioned input driven shaft 167, so that the above-mentioned input movable piece 163 can be raised and lowered corresponding to the drive of the above-mentioned input driving motor 165; and the input pressure roller portion 169, one end of which is fixed to one surface of the above-mentioned input setting frame 164 at a prescribed interval, and the other end can apply pressure to the upper surface of the input output medium corresponding to the descent of the above-mentioned input movable piece 163.

[0047] The above-mentioned input pressure roller portion 169 includes: an input pressure roller setting component 1691, which is formed with an input pressure roller fixing piece 1691a fixed to one side of the input setting frame 164 by a plurality of bolts and nuts, and is formed by input pressure roller bending pieces 1691b respectively connected in one direction and bent downward from both ends of the above-mentioned input pressure roller fixing piece 1691a; an input pressure roller rotating component 1692, the middle part of which is rotatably connected to the downwardly bent part of the above-mentioned input pressure roller setting component 1691 by a rotating pin, and an input working piece 1692a bent upward is formed on the inner side surface; an input pressure roller 1693 is rotatably set at one end of the above-mentioned input pressure roller rotating component 1692, and can move the above-mentioned input movable piece 163 in accordance with the descent of the above-mentioned input pressure roller. Applying pressure to the upper surface of the input output medium; an input tension spring 1696, one end of which is clamped on the first input fixing rod 1694 provided at the other end of the above-mentioned input pressure roller rotating component 1692, and the other end is clamped on the second input fixing rod 1695 fixed on the one-direction bent portion of the above-mentioned input pressure roller setting component 1691, so as to be able to constantly pull the other end of the above-mentioned input pressure roller rotating component 1692; and an input sensor part 1697, which is fixed on the inner side surface of the one-direction bent portion of the above-mentioned input pressure roller setting component 1691, and operates by the approach of the above-mentioned input working piece 1692a in correspondence with the upward rotation of one end of the above-mentioned input pressure roller rotating component 1692, and is used to set the initial pressure of the above-mentioned input pressure roller 1693 based on the application of a working signal to the control part side.

[0048] That is, since the control unit controls the driving time of the input drive motor in accordance with the thickness of the output medium input into the input unit, the input pressure roller applies greater pressure to a thicker output medium and less pressure to a thinner output medium, thereby enabling the output medium to be stably input in accordance with the thickness of the output medium.

[0049] The flattening pressure unit 170 is located behind the setting component 150 by being arranged at one end and the other end on the printing fixing plates on both sides of the upper surface of the frame 110 in a liftable manner. The surface is printed by the inkjet head 140 and pressure is applied to the upper surface of the output medium being transported corresponding to the thickness to flatten the output medium, thereby stably printing on the surface of the output medium.

[0050] The flattening pressurizing unit 170 includes: a flattening movable sheet 173, one end and the other end of which are connected to the respective surfaces of the printing fixed sheet 171 fixedly set on both sides of the upper surface of the frame 110 by a pair of linear guide rails 172 as a medium, and can be moved in the up and down directions; a flattening setting frame 174, one end and the other end of which are fixed to the respective surfaces of the flattening movable sheet 173; a flattening driving motor 175, which is fixed to one side of the flattening setting frame 174 and includes a flattening speed reducer 175a so as to be driven in accordance with the control of the control unit; a flattening driving shaft 176, one end of which is connected to the flattening speed reducer 175a and the other end of which forms a flattening driving gear portion 176a for power transmission; and a flattening driven shaft 177 , one end of which is gear-engaged with the flat driving gear portion 176a of the above-mentioned flat driving shaft 176, and the other end passes through the above-mentioned flat movable piece 173 to be rotatably arranged, forming a flat driven gear portion 177a at the end; a flat rack portion 178, which is fixedly set on each surface of the above-mentioned flat fixed piece 171, and is gear-engaged with the flat driven gear portion 177a of the above-mentioned flat driven shaft 177, and can make the above-mentioned flat movable piece 173 rise and fall in response to the drive of the above-mentioned flat driving motor 175; and a flat pressure roller portion 179, one end of which is fixed to one surface of the above-mentioned flat setting frame 174 at a prescribed interval, and the other end can apply pressure to the upper surface of the input output medium in response to the descent of the above-mentioned flat movable piece 173.

[0051] The flat pressure roller portion 179 includes: a flat pressure roller setting component 1791, which is formed with a flat pressure roller fixing piece 1791a fixed to one side of the flat setting frame 174 by a plurality of bolts or nuts, and is composed of flat pressure roller bent pieces 1791b bent in one direction from both ends of the flat pressure roller fixing piece; a flat pressure roller rotating component 1793, the middle part of which is rotatably connected to the flat pressure roller bent piece 1791b of the flat pressure roller setting component 1791 by a rotating rod 1792, and a flat working piece 1793a bent upward is formed on the inner side surface; a flat pressure roller 1794, which is rotatably set at one end of the flat pressure roller rotating component 1793, and has a width greater than that of the input pressure roller 1693, so as to adjust the input output in accordance with the descent of the flat movable piece. Pressure is applied to the upper surface of the medium to flatten it; a pair of flattening tension springs 1797, each one end of which is clamped to the two ends of a rotation locking rod 1795 provided at the other end of the above-mentioned flattening pressure roller rotating component 1793, and the other end is respectively clamped to the two ends of a fixed locking rod 1796 fixed on the flattening pressure roller bending piece 1791b of the above-mentioned flattening pressure roller setting component 1791, so that the other end of the above-mentioned flattening pressure roller rotating component 1793 can be pulled continuously; and a flattening sensor part 1798, which is fixed to the inner side surface of the flattening pressure roller bending piece 1791b of the above-mentioned flattening pressure roller setting component 1791, and works by approaching the above-mentioned flattening working piece 1793a in response to the upward rotation of one end of the above-mentioned flattening pressure roller rotating component 1793, and is used to set the initial pressure of the above-mentioned flattening pressure roller 1794 based on the working signal applied to the control part side.

[0052] The above-mentioned discharge pressure unit 180 is located in the discharge part by being arranged on both sides of the upper surface of the above-mentioned frame 110 in a liftable manner at one end and the other end. It can apply pressure to the upper surface of the output medium corresponding to the thickness to stably discharge until printing is completed on the surface of the output medium and discharge is completed after passing through the above-mentioned vacuum adsorption part 125. This is the same as the structure of the above-mentioned input pressure unit 160, so its detailed description is omitted.

[0053] In the case of printing an output medium having a thickness of 0.2 mm by the hybrid inkjet printer capable of continuous output of the present invention as described above, Figures 1 to 11 As shown, first, the content to be printed and the thickness of the output medium are input through the display unit of the control unit.

[0054] Then, one end of the output medium is put into the input portion and is placed so as to contact the front surface of the setting rod 152 of the setting member 150 .

[0055] As described above, when the output medium is set on the setting rod 152 of the setting member 150, the foot switch is pressed by the foot.

[0056] By pressing the foot switch, the input drive motor 165 of the input pressurizing unit 160 is driven under the control of the control unit.

[0057] Since the input movable piece 163 is moved downward by the drive of the input drive motor 165, the input pressure roller 1693 of the input pressure roller portion 169 arranged at fixed intervals on the front surface of the input setting frame 164 is located on the upper surface of the output medium.

[0058] In this case, if the input sensor unit 1697 detects the input working piece 1692a while the input pressure roller 1693 is located on the upper surface of the output medium, the input drive motor 165 is stopped by applying it to the control unit side under the control of the above-mentioned control unit.

[0059] In this case, the stop of the input drive motor 165 indicates that no output medium is input. When the input drive motor 165 stops, the control unit drives the input drive motor 165 for several seconds according to the thickness of the output medium input in advance.

[0060] Therefore, the input pressure roller 1693 applies pressure to the upper surface of the output medium.

[0061] As described above, when the input pressure roller 1693 applies pressure to the upper surface of the output medium, the setting rod 152 of the setting member 150 is moved upward under the control of the control unit.

[0062] When the setting rod 152 of the setting member 150 rises, the transport mesh belt 120 moves in response to the control of the control unit and the driving of the drive motor, and thus the output medium is transported to the lower side of the inkjet head rail 130 .

[0063] When the output medium is transferred to the lower side of the inkjet head rail 130 , the flattening driving motor 175 of the flattening pressurizing unit 170 is driven under the control of the control unit.

[0064] By driving the flattening drive motor 175 , the flattening pressure roller 1794 of the flattening pressure roller unit 179 applies pressure to the surface of the output medium being conveyed in the same operating sequence as the input pressure unit 160 .

[0065] Therefore, the output medium becomes flat and is transferred to the discharge side. During the transfer to the discharge side, the inkjet head 140 moves back and forth linearly along the inkjet head rail 130 under the control of the control unit and prints on the surface of the output medium.

[0066] As described above, when the output medium is transferred to the discharge portion, the discharge pressurizing unit 180 applies pressure to the surface of the output medium transferred in the same operating sequence as the input pressurizing unit 160 , through the control unit.

[0067] Therefore, the output medium is stably transferred and printing on the surface is completed.

[0068] As described above, the input pressure unit, the flattening pressure unit, and the discharge pressure unit provided on the upper surface of the transport mesh belt can complete printing while stably moving the output medium, thereby reducing the defective rate caused by printing.

[0069] The above description is only an example of the technical idea of ​​the present invention. Anyone skilled in the art of the technical field to which the present invention belongs can make various modifications and changes without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are used to illustrate the technical idea of ​​the present invention, but are not used to limit the technical idea of ​​the present invention.
