Description

Technology Field

[0001] The present invention relates to a nozzle of a liquid packaging machine for injecting a viscous liquid (e.g., red ginseng extract, jelly, detection medicine, etc.) into a liquid tubular container, and more specifically, to a nozzle assembly of a liquid packaging machine that can effectively and stably block the injection of a liquid other than the specified amount when injecting the liquid into the container through the nozzle. Background Technology

[0002] Generally, a liquid tube-type container is designed to allow drinking of a viscous liquid inside the container by cutting and opening one side of the tube, and as in Registered Patent Publication No. 10-0538048 (hereinafter referred to as 'Prior Patent 1'), a nozzle tube of a liquid packaging machine is connected to the container injection port, and a certain amount of liquid is injected into the container.

[0003] When liquid is injected through the container inlet of the nozzle tube applied to the liquid packaging machine described above, the container expands. When the nozzle tube is separated from the container inlet after the injection of liquid is completed, the expanded container temporarily contracts back to its original shape, causing the liquid inside the container to overflow through the container inlet. This resulted in unsanitary problems, such as contamination of the liquid packaging machine and its surroundings.

[0004] Accordingly, to improve upon the problem of prior art patent 1 as described above, registered patent publication No. 10-1780859 (hereinafter referred to as 'prior art patent 2') was disclosed, which includes a washing unit for washing and drying the inlet of a container filled with liquid.

[0005] However, the washing unit of the above prior art 2 was for washing / drying the container injection port, and was not able to wash the nozzle tube of the liquid packaging machine.

[0006] Accordingly, conventionally, when the supply of viscous liquid to a container through the nozzle tube of a liquid packaging machine is temporarily interrupted or when a temperature difference occurs due to injection, the viscous liquid may solidify and stagnate inside the nozzle tube and / or inside the hose connected to the nozzle tube. Consequently, when the injection of liquid is resumed, the stagnant solidified liquid prevents smooth injection into the container. In severe cases, this causes a portion of the supply tube of the liquid packaging machine connected to the nozzle tube via a hose to swell and burst due to the stagnant solidified liquid, or causes the liquid packaging machine to stop the injection of liquid.

[0007] Accordingly, the applicant disclosed Registered Patent Publication No. 10-2235021 (hereinafter referred to as 'Prior Patent 3') to improve the above-mentioned problem.

[0008] However, in the applicant's prior art patent 3 described above, the nozzle assembly applied to the liquid packaging machine had a problem in that the inclined nozzle end of the liquid blocking member (e.g., control rod) located inside the nozzle tube came into contact with the inner inclined surface of the nozzle to suppress the discharge of the liquid, and the present invention aims to improve this.

Specific details for implementing the invention

[0023] Hereinafter, embodiments of the present invention will be described with reference to the attached drawings.

[0024] FIG. 1 is an exploded perspective view showing the structure of a nozzle assembly applied to a liquid packaging machine according to a first embodiment of the present invention, FIG. 2 is a combined cross-sectional view showing the structure of a nozzle assembly applied to a liquid packaging machine according to a first embodiment of the present invention, FIG. 3 is an enlarged view of the upper part of FIG. 2 according to a first embodiment of the present invention, FIG. 4 is an enlarged view of the lower part of FIG. 2 according to a first embodiment of the present invention, and FIG. 5 is a schematic exploded cross-sectional view of the structure of a pin member fluid according to a first embodiment of the present invention.

[0025] Referring to the attached FIGS. 1 to 5, the nozzle assembly of a liquid packaging machine according to the first embodiment of the present invention receives a first liquid from a supply member described in the applicant’s prior registered patent, Patent Publication No. 10-2235021, and then injects it into a liquid tube-shaped container, and comprises a fixed body (10), an actuator (20), a nozzle body (30), a nozzle tube (40), a nozzle (50), a pin member fluid (60), a pin member for blocking liquid (70), and a spring (80).

[0026] The above fixed body (10) is a structure that is fixed vertically to the liquid packaging machine.

[0027] The actuator (20) is an air cylinder type actuator coupled to one end of the fixed body (10), and includes a linearly flowing actuator (21).

[0028] The nozzle body (30) has one end connected to the other end of the fixed body (10) through a connecting part (31), thereby forming a liquid injection port (30a) that allows for vacuuming of the container and subsequent injection of a first liquid into the container.

[0029] The nozzle tube (40) has its other end connected to the nozzle body (30).

[0030] The nozzle (50) is detachably coupled to a nozzle cap (52) formed at the other end of the nozzle tube (40), and an inclined ejection hole (51) is formed in the upper interior of the nozzle cap (52).

[0031] The above pin member fluid body (60) is received in the above fixed body (10) and connected to the above actuator (21), and linear flow is achieved in the opening or closing direction by the above actuator (21) which flows linearly according to the driving of the above actuator (20), and this includes a flow part (61), a pin member restraint part (62), and a spring pressing part (63).

[0032] The above-mentioned fluid section (61) is connected to the above-mentioned actuator (21) and moves in conjunction to flow in a straight line in a direction that opens the ejection hole (51) of the nozzle cap (52) which is coupled to the nozzle (50) or in a direction that blocks the ejection hole (51) of the nozzle cap (52).

[0033] The pin member restraint part (62) is received in the fluid part (61) and restrains one end of the pin member (70) for blocking liquid.

[0034] That is, a U-shaped groove (62a) is formed in the pin member restraint portion (62) so that one end of the pin member (70) for blocking liquid is restrained therefrom.

[0035] The spring pressing part (63) is coupled to the fluid part (61) after penetrating the liquid blocking pin member (70), which is restrained at one end by the pin member restraining part (62). A ring groove (63a) is formed on the outer surface of one end to which the side of the fluid part (61) is fitted, and the spring (80) is configured to press when the fluid part (72) moves in a straight line in the blocking direction.

[0036] Here, on the inner surface of the spring pressing part (63), a spring upper locking step (63d) and a step (63c) for inhibiting the movement section (d2) of the liquid blocking pin member (70) can be formed at the inner upper and middle positions of the internal spring receiving space (63b) so as to absorb the downward movement of the liquid blocking pin member (70) despite the downward movement of the spring pressing part (63) within the cushioning distance (d1) of the pin member of the spring (80).

[0037] The above-mentioned liquid blocking pin member (70) has one end connected to the pin member fluid (60) and penetrates the nozzle tube (40), and the other end has an inclined nozzle end (71) that contacts the inclined interior of the ejection hole (51) formed in the nozzle (50), and is configured to open or block the ejection hole (51) of the nozzle cap (52) coupled to the nozzle (50) according to the straight flow of the pin member fluid (60).

[0038] Here, at one end of the pin member (70) for blocking liquid, a catch groove (72) that is caught and restrained in a U-shaped catch groove (62a) formed in the pin member restraint part (62), and a catch projection (73) for catching the spring (80) may be formed.

[0039] That is, the above-mentioned catch (73) is formed at the lower part of the above-mentioned catch groove (72) to enable the lower part of the spring (80) to be caught.

[0040] The above spring (80) is formed at one end of the above liquid blocking pin member (70) and is configured to cushion the pressure resulting from contact when the inclined nozzle end (71), which flows in a straight line to block the ejection hole (51) of the nozzle cap (52) coupled with the nozzle (50), comes into contact with the inclined interior of the ejection hole (51).

[0041] That is, the spring (80) performs the function of controlling and compensating for the height of the liquid blocking pin member (70), and is received between the spring pressing part (63) and the liquid blocking pin member (70).

[0042] The spring (80), which is elastically assembled to the upper end of the above-mentioned liquid blocking pin member (70), has a compressive force applied to its upper end by the upper locking step (63d) of the spring and a compressive force applied to its lower end by the locking step (73). Accordingly, when the above-mentioned movable part (61) moves in a straight line in the blocking direction and moves the above-mentioned spring pressing part (63) downward to press the spring (80), the above-mentioned liquid blocking pin member (70) moves downward, and the inclined nozzle end (71) of the above-mentioned liquid blocking pin member (70) comes into contact with the inclined inner surface of the above-mentioned ejection hole (51) formed in the above-mentioned nozzle (50), thereby suppressing the ejection of liquid.

[0043] Even when the ejection of liquid is suppressed in this manner, the spring pressing part (63) moves further downward. Since this additional movement of the spring pressing part (63) is absorbed by the spring (80) located in the internal spring receiving space (63b), the liquid blocking pin member (70) can maintain a stable contact state with the inclined inner surface of the ejection hole (51) formed in the nozzle cap (52) to which the inclined nozzle end (71) is coupled with the nozzle (50) without additional downward movement, thereby cushioning the pressure resulting from the contact and preventing excessive contact.

[0044] In this way, as shown in the attached FIGS. 1 to 5, the nozzle assembly of the liquid packaging machine according to the embodiment of the present invention first supplies containers one by one to the holder of a turntable that rotates at a certain time interval by the rotational force of the driving means through the pack supply unit, and the containers are moved to the next process, the multi-stage nozzle assembly, according to the rotation of the turntable, and accordingly, the first liquid is supplied to the liquid injection port (30a) of the nozzle body (30) forming the nozzle assembly, and the first liquid can be injected into the liquid tube-shaped container through the nozzle tube (40) and nozzle (50) coupled to the nozzle body (30).

[0045] Here, when the first liquid is injected into the container through the nozzle (50), the inclined nozzle end (71) of the liquid blocking pin member (70) penetrating the nozzle tube (40) is separated from the inclined ejection hole (51) inside the nozzle cap (52) which is coupled to the nozzle (50).

[0046] Meanwhile, when the injection of the first liquid into the container through the nozzle (50) is completed, the actuator (20) is driven, and the operating body (21) of the actuator (20) moves in a straight line in the blocking direction, and the pin member fluid body (60) connected to the operating body (21) moves in a straight line in conjunction.

[0047] The fluid portion (61) included in the above-mentioned pin member fluid body (60) is connected to the above-mentioned actuator (21), and since the pin member restraint portion (62) and the spring pressing portion (63) are combined with the above-mentioned fluid portion (61), the above-mentioned fluid portion (61), the above-mentioned pin member restraint portion (62), and the spring pressing portion (63) all flow in a straight line in the blocking direction.

[0048] And, since one end of the pin member (70) for blocking liquid that penetrates the spring pressing part (63) is restrained in the pin member restraint part (62), the pin member (70) for blocking liquid also flows in a straight line in the blocking direction, and the inclined nozzle end (71) comes into contact with the inclined interior of the ejection hole (51) formed on the inner upper surface of the nozzle cap (52) that is coupled with the nozzle (50), thereby blocking the ejection hole (51) and ending the first liquid injection into the container.

[0049] At this time, when the fluid (60) of the pin member flows in a straight line in the blocking direction, the spring (80) formed on the outer surface of one end of the pin member (70) for blocking liquid is compressed, thereby cushioning the contact pressure between the inclined nozzle end (71) of the pin member (70) for blocking liquid and the inclined interior of the ejection hole (51), and thereby, the problem of damage occurring when the inclined nozzle end (71) of the pin member (70) for blocking liquid excessively adheres to the inner inclined surface of the ejection hole (51) can be prevented.

[0050] In other words, when the fluid portion (61) included in the above-mentioned pin member fluid (60) descends according to the driving of the actuator (20), the pin member restraining portion (62) and the spring pressing portion (63) coupled to the above-mentioned fluid portion (61) move downward in sequence, and this downward movement leads to the downward movement of the above-mentioned liquid blocking pin member (70), whose upper end is restrained by the above-mentioned pin member restraining portion (62), so that the inclined nozzle end (71) of the above-mentioned liquid blocking pin member (70) comes into contact with the inclined interior of the ejection hole (51) formed in the nozzle cap (52) coupled to the above-mentioned nozzle (50), thereby blocking the injection of the first liquid into the container.

[0051] When the actuator (20) is further lowered in this first liquid blocking state, the inner upper surface of the fluid part (61) comes into close contact with the upper surface of the pin member restraining part (62), and then the liquid blocking pin member (70), whose upper end is restrained by the pin member restraining part (62), is further pressed. The additional downward movement of the liquid blocking pin member (70) absorbs the downward movement impact force of the liquid blocking pin member (70) despite the downward movement of the spring pressing part (63) within the pin member buffering distance (d1) of the spring (80) located between the movement section (d2) of the internal spring receiving space (63b) of the spring pressing part (63).

[0052] Accordingly, the inclined nozzle end (71) of the above-mentioned liquid blocking pin member (70) can maintain a stable close contact state without excessive friction with the inclined inner contact surface of the ejection hole (51) formed in the nozzle cap (52) that is coupled with the above-mentioned nozzle (50).

[0053] When the above-mentioned pin member fluid (60) flows in a straight line in the blocking direction, the spring (80) formed on the outer surface of one end of the above-mentioned pin member (70) for blocking liquid is compressed, thereby cushioning the contact pressure between the inclined nozzle end (71) of the above-mentioned pin member (70) and the inclined interior of the above-mentioned ejection hole (51), and thereby, the problem of damage occurring when the inclined nozzle end (71) of the above-mentioned pin member (70) excessively adheres to the inner inclined surface of the above-mentioned ejection hole (51) can be prevented.

[0054] Meanwhile, the attached FIGS. 6 to 11 illustrate a second embodiment of the present invention, which applies the configuration described in the first embodiment of the present invention as is, but is intended to explain an embodiment applied as a double supply pipe structure for simultaneously supplying different types of liquids with different viscosities or different contents even if they have the same viscosity.

[0055] For convenience in explaining the function of the present invention, the first liquid supplied through the liquid injection port (30a) of the nozzle body (30) is referred to as the first liquid (e.g., oil), and the second liquid supplied through the liquid injection port (32a) of the nozzle body (30) is referred to as the second liquid (e.g., water). However, either one or all of these may be non-viscous or low-viscosity liquids.

[0056] A second embodiment of the present invention is configured such that a first liquid (e.g., oil) is injected into the liquid injection port (30a) formed in the nozzle body (30), and a second liquid (e.g., water) is injected into the lower end of the nozzle body (30) by forming an auxiliary body (32) that forms an integrated structure or a detachable coupled structure with the nozzle tube (40), and the nozzle body (30) and the auxiliary body (32) are connected by a connecting body (33), and the nozzle tube (40) is configured with a double structure of a first supply pipe (41) and a second supply pipe (42) that receive the first liquid and the second liquid.

[0057] That is, the first supply pipe (41), which receives the first liquid as a first liquid, has one end connected to the auxiliary body (32) to supply the first liquid supplied from the liquid injection port (30a) of the nozzle body (30) downward, and the other end of the first supply pipe (41) can be screw-connected to accommodate the upper connecting part (52a) of the nozzle cap (52).

[0058] And, the second supply pipe (42), which receives the second liquid as a second liquid, has one end connected to the connecting body (33), and the upper end of the connecting body (33) is also closely connected to the nozzle body (30) to supply the second liquid supplied through the liquid injection port (32a) of the auxiliary body (32) to the lower end, and the other end of the second supply pipe (42) is closely fitted and connected to the supply pipe coupling groove (52b) processed on the upper end of the nozzle cap (52), so that the second liquid can be supplied in a state separated from the first liquid supplied through the first supply pipe (41).

[0059] In other words, the second supply pipe (42), which receives the second liquid and is inserted along the longitudinal direction inside the first supply pipe (41) that receives the first liquid, acts as a central separating wall that supplies the different types of liquids separately, thereby maintaining a double supply pipe structure in which the supply paths are separated, and the liquid blocking pin member (70) is installed inside the second supply pipe (42) that receives the second liquid.

[0060] And, at least one mixing passage (42a) is formed at the bottom of the second supply pipe (42) which acts as a central dividing wall, and the mixing passage (42a) supplies the first liquid, which is supplied between the first supply pipe (41) and the second supply pipe (42) along the first supply pipe (41), to the bottom of the second supply pipe (42) so that the first liquid and the second liquid can be mixed near the ejection hole (51) of the nozzle cap (52) which is coupled with the nozzle (50).

[0061] That is, the second liquid supplied through the second supply pipe (42) reaches the coupling part of the nozzle (50) while separated from the first liquid supplied through the first supply pipe (41), and as it approaches the ejection hole (51) of the nozzle cap (52) coupled to the nozzle (50), the first liquid supplied through the first supply pipe (41) passes through the mixing passage (42a) provided at the bottom of the second supply pipe (42), which is an adjacent passage, and then passes through the ejection hole (51) of the nozzle cap (52) coupled to the nozzle (50) to be mixed with the second liquid and supplied to the packaging container.

[0062] At this time, the second liquid supplied to the packaging container by passing through the mixing passage (42a) provided at the bottom of the second supply pipe (42) and through the ejection hole (51) of the nozzle cap (52) does not require a separate pin member for blocking the liquid, and the function of the pin member (70) for blocking the liquid, which supplies or blocks the first liquid supplied through the first supply pipe (41), is sufficient.

[0063] This is because, when the inclined nozzle end (71) of the pin member (70) is in close contact with the inner inclined surface of the ejection hole (51) as the pin member fluid (60) moves linearly in the blocking direction while located inside the first supply pipe (41), the supply of the first liquid and the second liquid mixed near the ejection hole (51) of the nozzle cap (52) coupled with the nozzle (50) is stopped, and therefore, no change in pressure occurs inside the first supply pipe (41) and the second supply pipe (42).

[0064] Hereinafter, parts identical to those in the attached FIGS. 1 to 4, which are the first embodiments of the present invention, are indicated by the same reference numerals, and redundant descriptions thereof have been omitted.

[0065] Although the technical concept of the nozzle assembly of the liquid packaging machine of the present invention has been described above together with the attached drawings, this is merely an illustrative description of the best embodiment of the present invention and is not intended to limit the present invention.

[0066] Accordingly, the present invention is not limited to the specific preferred embodiments described above, and anyone with ordinary knowledge in the art to which the invention pertains can make various modifications without departing from the essence of the invention as claimed in the claims, and such modifications will be within the scope of the claims.
