The nozzle fixing skirt portion 33 has an inner circumferential surface of the central opening portion 31 of the cap-shaped body when the upper cap 30 is assembled with the opening portion 1a of the ink cartridge 1 or the lower cap 10. Accordingly, the nozzle 21 can be firmly pressed and fixed.

Fig. 6 is a perspective view illustrating a state where an ink cartridge opening and closing apparatus according to the present invention is used, and illustrates a state of use provided in an opening of an ink cartridge for storing and discharging a fluid having high viscosity and viscosity such as ink.

The assembling operation of the ink cartridge opening and closing apparatus according to the present invention configured as described above and its operation and effect will be described as follows.

First, when the lower cap 10 is pressed toward the body of the ink cartridge while the center opening 11 of the lower cap 10 corresponds to the opening 1a of the ink cartridge 1, the lower cap 10 The cartridge coupling groove 13 and the cartridge coupling protrusion 14 formed on the inner circumferential surface thereof correspond to the opening portion 1a of the ink cartridge, thereby completing the assembly of the lower cap. When the assembling of the lower cap is completed, the annular sleeve 17 protruded horizontally from the outer circumferential surface of the lower cap 10 surrounds the edge around the opening 1a of the ink cartridge 1. As a result, the lower cap 10 may be firmly assembled to the opening portion 1a of the ink cartridge 1 by the cartridge coupling groove 13 and the cartridge coupling protrusion 14.

Next, the protrusion of the nozzle 21 is positioned toward the body of the ink cartridge 1 so that the valve 20 is seated on the central opening 11 of the lower cap 10. At this time, the valve 20 corresponds to the valve seating groove 12 formed along the edge of the central opening 11 of the lower cap 10 such that the annular flange 22 of the valve 20 is seated.

Finally, the upper cap 30 is positioned by matching the central opening 11 of the lower cap 10 with the central opening 31 of the upper cap 30 while the valve 20 is seated. When the upper cap 30 is pressed toward the lower cap 10 in the state, the lower cap coupling groove of the upper cap 30 to the upper cap coupling protrusion 15 and the upper cap coupling groove 16 of the lower cap 10. 34 and the lower cap coupling protrusion 35 correspond to each, and the assembly is completed. At this time, the upper cap 30 is the elastic skirt portion 32 is composed of at least one or more elastic pieces (32a, 32b), so that the two or more elastic pieces (32a, 32b) provided by the elastic skirt portion (32) The upper cap 30 can be detachably attached to the opening 1a of the ink cartridge 1 or the lower cap 10 by the elastic force.

In this process, the upper cap coupling protrusion 15 formed on the outer circumferential surface of the lower cap 10 is seated in the lower cap coupling groove 34 of the upper cap 30, and the upper cap coupling groove of the lower cap 10 ( 16, the lower cap coupling protrusion 35 of the upper cap 30 is seated, thereby preventing the upper cap 30 from being separated from the lower cap 10.

When the assembly of the upper cap 30 is completed as described above, the valve 20 is firmly fixed by the nozzle fixing skirt portion 33 of the upper cap 30.

Therefore, when there is no change in the internal pressure of the ink cartridge, that is, when the ink cartridge is not pressed, the nozzle 21 of the valve 20 is connected to the self-sealing means composed of the cross cut 21a or the Y cut 21b. Since the state of sealing by itself is maintained, the internal space of the ink cartridge is in a state capable of being sealed from the outside.

Therefore, in the future, when the external pressure is applied to or removed from the body of the ink cartridge, the pressure is applied to the inside of the ink cartridge, thereby opening itself and discharging the fluid, or sealing itself by the elasticity of the rubber to automatically flow the fluid. You can crack down. That is, when an external force is applied, the cross-cutting portion 21a or the Y-shaped cutting portion 21b, which is a self-sealing means formed by elasticity of the silicone rubber, is opened and the fluid is discharged, or when the external force is removed, Self-sealing by elasticity, the flow of fluid is automatically interrupted.

In particular, since the valve 20 mounted on the opening and closing device of the present invention is a U-shaped nozzle 21 which protrudes convexly toward the body of the ink cartridge and has a cutout at its central portion, the silicone rubber is directed toward the body of the ink cartridge in the normal state. Has resilience Therefore, when the internal pressure of the ink cartridge is increased, the incision is opened by an external force directed toward the body of the ink cartridge, and the flow of fluid is started. When the increased pressure is removed from the inside of the ink cartridge, the body of the ink cartridge is removed. The incision is automatically sealed by the restoring force directed toward to interrupt the flow of the fluid. Thus, in the case of using the valve according to the present invention, not only the flow of fluid with high viscosity and viscosity, such as ink, can be easily controlled, but also the restoring force acting in a direction opposite to the flow of the fluid discharged from the ink cartridge. Automatic cutting allows the end of the fluid to be cut neatly.

The pressurizing unit 120 applies pressure to the ink cartridge 110 to induce ejection of ink. The pressurizing unit 120 is installed above the ink cartridge 110 to induce discharge of ink by applying pressure to one end (hereinafter, referred to as an upper surface) opposite to the end where the opening and closing device of the ink cartridge 110 is located. can do.

As illustrated in FIG. 7, the pressurizing unit 120 is connected to the hollow type stepping motor 710 by a screw in the center hole of the stepping motor 710 to move up and down as the stepping motor 710 is driven. It comprises a drive shaft 720 having a spiral groove and a pressure plate 730 is fixedly connected to one end of the drive shaft 720 to apply pressure to the top surface of the ink cartridge 110.

Common pressurization systems use hydraulic or pneumatic cylinders, or electric cylinders. In addition, the cylinder applied to the existing system has a high output, but the reaction rate is poor or it is difficult to fine-tune the output.

In the present invention, in order to precisely adjust the amount of ink discharged from the ink cartridge, it is characterized in that it comprises a pressing unit which can finely adjust the pressure applied to the ink cartridge. Specific operating principle of the pressing unit 120 of the present invention will be described in detail below.

In general, the motor is used in many transfer systems, in the present invention constitutes a pressurizing unit with a motor of the hollow type.

The hollow type stepping motor 710 of the pressurizing unit 120 operates in a fixedly installed state. In general, the driving shaft 720 only performs a simple rotational movement in a state in which the driving shaft 720 is not fixed. However, when the driving shaft 720 is fixed, the driving shaft 720 does not rotate as the motor is driven, and linearly reciprocates. Specifically, when the stepping motor 710 rotates in the forward direction, the spiral groove formed in the drive shaft 720 moves downward at a constant speed. Accordingly, the pressure plate 730 fixed to the drive shaft 720 is connected to the ink cartridge. It is possible to apply a constant pressure to the upper surface of (110). Thereafter, when the stepping motor 710 rotates in the reverse direction, the driving shaft 720 is moved at a constant speed in the upward direction by the same principle as described above, so that the pressure plate 730 is applied to the upper surface of the ink cartridge 110. Losing pressure decreases at a constant rate.

On the contrary, when the stepping motor 710 rotates in the reverse direction, the driving shaft 720 moves at a constant speed in the downward direction, and thus the pressure plate 730 fixed and connected to the driving shaft 720 is the upper surface of the ink cartridge 110. A constant pressure may be applied thereto, and when rotated in the forward direction, the pressure plate 730 may move at a constant speed in the upward direction to reduce the pressure applied to the upper surface of the ink cartridge 110 at a constant speed.

As such, the present invention does not use hydraulic, pneumatic, or electric cylinders to pressurize the ink cartridge, but connects through a spiral groove through a spiral groove in the center hole of the stepping motor of the hollow type and the stepping motor. By finely adjusting the linear motion of the drive shaft by using the driven drive shaft and precisely controlling the motor, the amount of ink discharged from the ink cartridge can be finely adjusted.

For example, as a method for fine-tuning the ink, when the screw thread spacing of the drive shaft (Screw) is 2mm, when the pressurizing stepping motor is rotated by one rotation, the flanger in the ink cartridge is 2mm. Due to the nature of the stepping motor, a signal can be sent by dividing one rotation more than 500 times, so it is possible to finely control the amount by dividing 2mm by 500 times, and the amount of ink is fed back through the balance value, but the desired amount is calculated by the length of the drive shaft. It is also possible to discharge ink.

A turn table 130 is installed under the pressurizing unit 120 so that the ink cartridge 110 can be accommodated with a sufficient margin, and has a plurality of holes, and a plurality of ink cartridges in the plurality of holes. House 110. Preferably, as shown in FIG. 8, the turn table 130 includes a circular upper plate 810 having a plurality of holes and a circular lower plate 820 having holes at positions corresponding to the upper plate 810. It is configured to include a plurality of vertical support 830 for supporting the upper plate 810 and the lower plate 820 spaced apart.

Here, the plurality of holes formed in the upper plate 810 has a larger diameter than the ink cartridge 110 so as to accommodate the circular ink cartridge 110, and the plurality of holes formed in the lower plate 820 may include ink cartridges ( It has a diameter in the range between the opening and closing device protruding from the ink cartridge 110 and the diameter of the groove formed in the top plate 810 to support 110.

On the other hand, the turn table 130 is supported by the servo motor 850 installed on the horizontal support 840, the rotation axis of the servo motor 850 passes through the horizontal support 840, the lower plate of the turn table 130 820 is connected to the center of the. That is, the turn table 130 is connected to the rotary shaft of the servo motor 850, and rotates as the server motor 850 is driven, thereby storing a specific ink cartridge 110 to store necessary ink according to the input ink mixing ratio. ) May be positioned below the pressing unit 120.

In addition, a specific portion of the horizontal support 840 located in line with the pressing unit 120 is characterized in that a hole is formed so that ink discharged from the ink cartridge 110 can pass therethrough.

Below the servo motor 850, a stirring plate 140 spaced apart from each other with a predetermined space is positioned to receive ink discharged from the ink cartridge 110. And the stirring plate 140 is located on the scale 150, the weight information of the measured ink is transmitted to the control unit 160 in real time.

The controller 160 controls the pressure applied to the upper surface of the ink cartridge 110 so that the predetermined ink is discharged to the stirring plate 140 according to the input ink mixing ratio. When the user determines a compounding ratio of ink having a specific color to make a specific color, and inputs it to an input unit (not shown) operated by, for example, a touch screen method, the control unit discharges ink having a specific color according to the input blending ratio. Will lead to.

Here, the mixing ratio of the ink refers to the weight ratio of the ink, the weight of each ink required for the coloration is input by the user, respectively, can be induced to be discharged to the stirring plate 140 as much as the weight actually input, or When the total weight of the ink required for toning and the weight ratio thereof are input, the controller 160 calculates the weight of each ink according to the blending ratio of the ink to the total weight, thereby inducing each of the ink to be ejected by the calculated weight. Can be.

For example, suppose you want to produce color A, and you need three colors of ink a, ink b, and ink c. When the user inputs an actual weight value into the input unit such that ink a: 20g, ink b: 40g, and ink c: 60g are discharged in the first embodiment, the controller 160 controls the respective inks so that ink of the corresponding weight is discharged. The pressure applied to the upper surface of the cartridge 110 is adjusted.

If the user inputs a compounding ratio of ink a: ink b: ink c: 1: 2: 3 and a total weight of 120 g as the second embodiment through the input unit, the control unit 160 determines the ink a: 20 g, from the input values. It is calculated that ink b: 40g and ink c: 60g are required, and as a result, each of the ink is discharged by the calculated weight.

   In a third embodiment, the user can input the ink compounding ratio through mode selection. According to the present invention, the ink compounding ratio input according to the first and second embodiments can be stored in a mode according to the case, and then the user can print each ink as in the first and second embodiments so as to produce the same color. The ink of the same color can be manufactured by selecting and inputting any one of the stored modes, without having to input the weight value or the compounding ratio for each.

In addition, the controller 160 controls the operation of the servo motor 850 of the pressurizing unit 120 so that the ink of the corresponding weight is discharged to the stirring plate 140 according to the input ink mixing ratio so that a specific ink cartridge is pressurized unit 120. Control to rotate the turntable 130 so that it can be positioned below. That is, the controller 160 rotates the turn table 130 when the 20 g ink a discharge is completed, so that the corresponding ink cartridge can be positioned under the pressurizing unit 120 to discharge the ink b.

To this end, the plurality of ink cartridges 110 are accommodated in the turn table 130 at a constant angle, and the holes in which the ink cartridges 110 are accommodated have a unique identifier. The controller 160 adjusts the rotation angle of the servo motor 850 so that a hole having a unique identifier can be positioned below the pressing unit 120. The user may perform matching of an ink cartridge having a specific color with a hole having a specific unique identifier through the initial environment setting.

For more accurate control of the specific ink weight ejected, the controller 160 preferably transmits the weight of the ink measured in real time by the scale 150. The controller 160 may determine the rotation timing by comparing the weight of the specific ink transmitted with the input ink weight corresponding thereto.

For example, suppose you want to make color A, you need three colors of ink a, ink b, ink c, and the input values are ink a: 20g, ink b: 40g, ink c: 60g. Initially, the ink a cartridge is set to be accommodated in the groove having the unique identifier A, the ink b cartridge is in the groove having the unique identifier B, and the ink c cartridge is accommodated in the groove having the unique identifier C, each of which is They are separated by 30 ° apart.

The controller 160 controls the rotation of the server motor 850 so that the groove in which the ink a cartridge is accommodated is located below the pressing unit 120 by the input value, and the current flowing through the stepping motor 710 is controlled. By controlling the driving speed of the stepping motor 710 by adjusting the pressure applied to the upper surface of the ink cartridge 110 by the pressure plate 730 so that 20g of ink a is discharged at a constant speed.

The controller 160 receives the weight of the ink a measured by the scale 150 in real time. When the weight of the received ink a is 20 g, it is compared with the input value. After a predetermined time, the server motor 850 places the groove in which the ink b cartridge is accommodated under the pressurizing unit 120. Control to rotate by 30 °.

On the other hand, the automatic color rendering apparatus according to the present invention is characterized in that it can perform a feedback (feedback) function. Originally, toning a specific color requires precise control, making the same color is not practically easy. For example, even when a color matching operation is performed using an ink compounding ratio for producing color A, it is not easy to obtain substantially the same color as color A. Therefore, in order to produce the same color A, it is necessary to adjust the blending ratio of the ink to be blended.

The reason why the feedback function is required in performing the toning work is, firstly, due to the limitation of human vision. Color is transmitted differently to the human field of view depending on the intensity of the light, the color of the light, the angle of the light, and the angle the viewer sees. In other words, it is not practical to manufacture the same color by subjective visual differences, optical illusions and the influence of the surrounding environment.

Second, a feedback function is required to perform the toning operation due to the limitations inherent in the ink itself. Colors can be categorized into three categories: black, which feels heavy by weight, white, which feels bright, and middle, red and yellow, which are particularly difficult to produce the same color.

In order to solve the above problem of toning operation, the automatic toning apparatus according to the present invention provides a feedback function, the specific operation of which is as follows.

For example, suppose you want to make color A, you need three colors of ink a, ink b, ink c, and the input values are ink a: 20g, ink b: 40g, ink c: 60g. When the ink for each of the inks required for the production of the color A is discharged to the stirring plate 140 by the corresponding weight inputted by the automatic color matching device according to the present invention, the user stirs them to produce the color A.

In this case, in the case where the color desired by the user does not come out due to the limitation in the above-described coloration operation, the user can automatically (operate the automatic coloration device so that a specific ink is discharged by a specific weight) or manually (the user directly stirs the plate). To adjust the color by adding a specific ink).

For color adjustment, the weight of the ink newly added to the stirring plate 140 is measured by the scale 150, and the measured weight value is transmitted to the controller 160, and the controller 160 The new ink compounding ratio reflecting the weight is calculated and stored in a memory element including an internal memory device. For example, assuming that the user automatically adds ink a automatically or manually, and that the weight of the newly added ink a by the scale 150 is 10 g, the controller 160 controls the ink a for producing the color A, b, c Add 10 g to the original total weight of 120 g, calculate the ratio of each of the ink a, b, c to the total weight of 130 g to calculate the new ink compounding ratio for producing the color A, and store it in the storage element.

By using the feedback function, the user selects and inputs the stored new ink compounding ratio, so that the same color as the color A can be manufactured next time.

According to the present invention, by the control unit 160 performs such a process, by discharging the ink corresponding to the input compounding ratio to the stirring plate through the precise control, it is possible to realize a uniform quality even if nobody is working, even if novice can do.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
