Description

Automatic reusable cup lid cleaning system

[0001] The present invention relates to an automatic reusable cup lid washing system in which the entire process of loading and aligning reusable cup lids in consideration of the interval between the washing positions of the reusable cup lids, moving the aligned cup lids to the washing position, washing, and moving the washed cup lids to the discharge position is automatically performed by a single system.

[0002] To protect the natural environment, reduce plastic use, and reduce carbon emissions, synthetic resin cups and lids are now being manufactured and supplied for reuse. To achieve this, it's crucial to collect discarded cups and lids from cafes, coffee shops, and other sources of waste, then clean and reuse them.

[0003] However, because cups and lids are traditionally washed manually, the cleaning process is inherently inefficient, highly unproductive, and ineffective. Cup lids, in particular, can have a variety of designs, and because their joint structures include curved surfaces, manual cleaning of these areas is inherently limited. Furthermore, the degree of cleaning varies depending on the worker's skill level, leading to problems such as inconsistent cleaning.

[0004] Accordingly, there is an urgent need in the related industry to develop a system that can more efficiently wash cups, especially cup lids, including those that are recycled.

[0052] The objects, specific advantages, and novel features of the present invention will become more apparent from the following detailed description and preferred embodiments, taken in conjunction with the accompanying drawings. In this specification, when reference numerals are assigned to components in each drawing, it should be noted that, where possible, identical components are given the same reference numerals even if they appear in different drawings. Furthermore, in describing the present invention, if a detailed description of a related known technology is deemed to unnecessarily obscure the gist of the present invention, the detailed description may be omitted.

[0053] Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the attached drawings.

[0054] Referring to FIGS. 1a, 1b, 2 to 5, the automatic reusable cup lid washing system according to the present invention can be largely composed of a frame part (100), an input conveyor part (200), a washing part (300), an output conveyor part (400), and an alignment chute part (500).

[0055] The frame (100) is intended to ensure that various facilities required for washing the cup lid can be safely installed in appropriate locations, and can be formed in an appropriate shape or size by comprehensively considering the washing capacity, etc.

[0056] The input conveyor unit (200) is employed to automatically input and move the cup lid (C1) before washing. This input conveyor unit may be arranged on one side of the inside of the frame, and may have a structure in which a belt-shaped or other alternative transport member with the same function as the belt-shaped transport member, through which the cup lid before washing is substantially lifted and transported, is rotatably hung on the frame and is transported while rotating in an infinite orbit by a motor (M1).

[0057] The cup lid (C1) before washing is fed through the above-mentioned feeding conveyor (200), and the feeding can be temporarily prevented while feeding only the amount of washing water set in advance by the feeding quantity detection sensor (210) and the first stopper (220). The first stopper (220) can be configured so that the feeding movement is temporarily prevented when the moving blocking bar (220b) is moved up and down by the operation of the cylinder (220a) and comes into contact with one side of the cup lid before washing.

[0058] Accordingly, the pre-wash cup lids (C1) fed through the feeding conveyor (200) are sequentially fed only in quantities preset by the counter of the feeding quantity detection sensor (210), and when the feeding of the preset quantity is completed, feeding is temporarily stopped by the first stopper (220) that operates in conjunction with the feeding quantity detection sensor, thereby enabling continuous feeding and stopping according to the pre-set feeding operation conditions of the pre-wash cup lids.

[0059] The washing unit (300) is for automatically washing the upper, lower, and side surfaces of the cup lid (C1) before washing that is moved from the input conveyor unit (200), and may be configured to include one or more washing pipes (310) that are arranged and fixed at an appropriate interval on one side of the input conveyor unit, and upper and lower washing units (320)(330) that are operated to be raised and lowered to an appropriate position in order to sequentially wash the upper, lower, and side surfaces of the cup lid before washing that is inserted inside the washing pipe while being loaded and simultaneously rotated in opposite directions with respect to the cup lid before washing (C1) to evenly wash the upper and lower surfaces using a washing liquid, or rotate in the same direction while simultaneously rotating the cup lid before washing (C1) in the same direction while evenly washing the side surfaces using washing water, or rotate the cup lid before washing in only one direction while simultaneously washing the upper, lower, and side surfaces using only washing water.

[0060] The above washing pipe (310) has a shape that is open at both ends, and the open ends are formed to have a shape that expands outward, so that the insertion of the cup lid (C1) before washing or the raising and lowering of the upper and lower washing parts (320)(330) can be smoothly performed.

[0061] The washing pipe (310) may be equipped with a washing liquid spray nozzle (312) for spraying washing liquid when washing the upper and lower parts of the cup lid (C1) before washing, and a washing water high-pressure spray nozzle (313) for spraying washing water at high pressure when washing the side parts of the cup lid (C1) before washing.

[0062] The cleaning liquid sprayed through the cleaning liquid spray nozzle (312) is supplied only when washing the upper and lower parts of the cup lid before washing, and the high-pressure cleaning water sprayed through the cleaning water high-pressure spray nozzle (313) can be selectively supplied and controlled only when washing the side parts of the cup lid before washing. However, the spray control of the cleaning liquid and cleaning water described above is only an example, and if necessary, the cleaning operation can be performed while spraying and supplying both simultaneously depending on the working conditions.

[0063] The upper washing part (320) performs a washing operation by being operated to rise and fall on the upper surface of the cup lid (C1) before washing that has been put into the washing pipe (310), and it is vertically installed through a movable frame (321) and a first support block (322) fixed to a fixed support bar (111) of a frame part (100) to operate the movable frame to rise and fall, and at the same time, a lower end is fixedly supported on the movable frame (321) and is operated to rise and fall by the forward and reverse rotation of a motor (M2), and a rotary tube (325) that is rotatably supported through a bearing by a rotation guide block (324) that is fixedly installed on the movable frame (321) so as to be arranged on the same vertical axis (P1) as the washing pipe (310), and a support head shaft (326a) is fitted inside the rotary tube, and a guide formed on the rotary tube It is configured to include a support head (326) that is fixedly installed to be walked on by a guide pin (326b) with respect to a home (325a) so as to be rotatable and move up and down, and at the same time, a brush (326c) that comes into contact with the upper surface of a cup lid before washing is provided at the lower end, and an elastic member (327) that is elastically installed on the outside of the support head shaft (326a) so as to be arranged between the upper part of the support head and the rotary tube (325) to provide elastic force to the support head, and each support head (326) may be configured to be rotatable and connected by a motor (M3) that moves up and down together with the movable frame (321).

[0064] Here, the lower surface of the brush (326c) equipped on the support head (326), i.e., the cleaning surface that comes into contact with the upper surface of the cup lid (C1) before washing for washing, may be formed to correspond to the shape of the upper surface of the cup lid before washing in order to provide more effective cleaning power.

[0065] As for the motor (M3) that simultaneously rotates the support head (326) through the above-mentioned rotary body (325), it is preferable to use two of them as illustrated in FIG. 2 to minimize the rotational load due to frictional contact of the brush (326c), but only one motor may be used if necessary.

[0066] Meanwhile, the lifting and lowering support shaft (323) that moves the movable frame (321) up and down can be induced to perform more stable lifting and lowering operations by having one end fixedly supported on the movable frame and the other end vertically installed through the fixed support bar (111) of the frame (100).

[0067] In addition, the motor (M2) for raising and lowering the movable frame (321) can be operated by signals from a detection rod (323a) provided on the raising and lowering support shaft (323) and a height adjustment detection sensor (323b) installed at an appropriate interval on a bracket (B1) fixedly installed on a separate fixed support bar (111), and through this, the raising and lowering movement distance of the support head (326) that is inserted into the washing pipe (310) to wash the upper surface and side surface of the cup lid (C1) before washing can be appropriately controlled.

[0068] The lower washing part (330) is for supporting and washing the lower surface of the cup lid (C1) before washing, which is put into the washing pipe (310) for washing, while being operated to rise and fall, and is vertically installed between the movable frame (331) and the upper and lower brackets (B2) (B3) provided on one side of the frame to raise and lower the movable frame, and has one side connected to the motor (M4) and the other side rotatably supported by the raising and lowering guide pipe (332) fixedly installed on the movable frame, and a guide rod (335) vertically supported by the second support block (334) fixedly supported by the bracket (B3) arranged at the lower end of both sides of the movable frame to induce stable raising and lowering of the movable frame, and a guide rod (335) fixedly installed on the movable frame (331) so as to be arranged on the same vertical axis (P1) as the washing pipe. It is configured to include a rotary tube (337) that is rotatably supported through a rotary guide block (336), a support head shaft (338a) that is fitted into the inside of the rotary tube and is fixedly installed to be hooked by a guide pin (337b) on a guide groove (337a) formed in the rotary tube so as to be able to rotate and move up and down, and at the same time, a support head (338) that is equipped with a brush (338c) that comes into contact with the lower surface of a cup lid (C1) before washing, and an elastic member (339) that is elastically installed on the outside of the support head shaft (338a) so as to be arranged between the lower part of the support head (338) and the rotary tube (337) to provide elastic force to the support head, and each support head (338) may be configured to be rotatably connected by a motor (M5) that moves up and down together with a movable frame (331).

[0069] Here, the upper surface of the brush (338c) equipped on the support head (338), i.e., the cleaning surface that comes into contact with the lower surface of the cup lid (C1) before washing for washing, may be formed to correspond to the shape of the lower surface of the cup lid before washing in order to provide more effective cleaning power.

[0070] In addition, it is preferable to use two motors (M5) that rotate each support head (338) through the above-mentioned rotary tube (337), as illustrated in FIG. 2, to minimize the rotational load due to frictional contact of the brush (338c), but only one motor may be used if necessary.

[0071] In addition, the movable frame (331) of the lower washing section (330) can induce a more stable lifting operation by having the rollers (339b) provided inside the roller cases (339a) fixedly installed on both sides of the movable frame move along the roller support rods (339c) installed vertically with respect to the frame during the lifting operation, as illustrated in FIG. 2.

[0072] In addition, the motor (M4) for moving the movable frame (331) up and down can be operated in a forward and reverse manner by signals from a detection rod (335a) equipped on a guide rod (335) on one side and a height adjustment detection sensor (335b) installed at an appropriate interval on a bracket (B3) at a corresponding position, and through this, the distance of movement of the support head (338) for moving up and down, which is inserted into the washing pipe (310) to wash the lower and side surfaces of the cup lid (C1) before washing, can be appropriately controlled.

[0073] The discharge conveyor unit (400) is arranged on one side of the washing unit to transport and discharge the washed cup lid (C2) that has been washed in the washing unit (300).

[0074] This discharge conveyor unit (400) may have a structure in which, like the input conveyor unit (200), the cup lid (C2) after washing is substantially lifted and transported in the form of a belt or other alternative transport member having the same function is rotatably hung on the frame and transported while rotating in an infinite orbit by a motor (M6).

[0075] The alignment chute (500) is for aligning and moving the pre-wash cup lid (C1) fed through the input conveyor (200) to the position of the washing unit (300), and at the same time, when the pre-wash cup lid is moved to the washing unit, the post-wash cup lid (C2) that has been washed in the washing unit is forcibly ejected to the discharge conveyor (400).

[0076] To this end, the alignment chute (500) of the present invention is configured to include a chute (510) that controls the pre-wash cup lid (C1) that is positioned directly above the input conveyor (200) and moves along it to be automatically aligned and released so that it is transferred and arranged on the same horizontal axis (P2) as the washing pipe (310) using the position detection sensor (512) and the second stopper (514), and at the same time, the pre-wash cup lid (C1) that has been aligned is moved to the upper part of the washing pipe (310) of the washing unit (300) by the forward and reverse rotation operation of the motor (M7) so that it is respectively introduced and returned to its original state, and on one side of the chute (510), an ejection unit (520) is provided to simultaneously eject the post-wash cup lid (C2) that has been washed in the washing unit from the washing pipe (310) to the discharge conveyor (400) in the process of the pre-wash cup lid being moved to the washing unit (300) through the chute (510). Can be.

[0077] The position detection sensor (512) and the second stopper (514) for guiding the cup lid (C1) before washing, which is moved inside the alignment chute (500), to be arranged on the same horizontal axis (P2) as the washing pipe (310), are each set as a pair and installed at each alignment position so that the cup lid before washing is arranged and aligned on the same horizontal axis (P2) as each washing pipe (310). At this time, the second stopper (514) is configured to align the cup lid before washing by contacting one side portion of the cup lid before washing while the movement blocking rod (514b) of the cylinder (514a) controlled by the signal of the position detection sensor (512) descends, and at the same time, when the forced alignment is completed, it rises again to release the forced alignment operation.

[0078] Accordingly, the pre-wash cup lids (C1) transferred into the chute (510) of the alignment chute (500) can be sequentially aligned and prevented from being placed on the same horizontal line as the washing pipe (310) by the position detection sensor (512) and the second stopper (514), and when the alignment is completed, the alignment state is forcibly released by the second stopper (514), so that each pre-wash cup lid (C1) can be very stably introduced into the washing pipe (310) of the washing section (300).

[0079] Meanwhile, the moving blocking rod (514b) of the second stopper (514) that automatically aligns the cup lid (C1) before washing to the correct position within the chute section (510) may be controlled to rise immediately after the automatic alignment of the cup lid before washing is completed, or, if necessary, may be controlled to rise after the cup lid before washing is inserted into the upper part of the washing pipe (310) of the washing section (300) while still in contact with one side of each cup lid before washing.

[0080] The above-mentioned alignment chute (500) is reciprocated from the input conveyor (200) toward the washing unit (300) by a motor (M7). It is configured so that one side is connected to the motor (M7) to transmit power, and at the same time, a pinion (517) is provided at both ends of a motor shaft (516) that is installed through the chute (510) so as to be rotatable on a bracket installed on the frame (100), and the pinion can be safely reciprocated without shaking by moving along the rack (518).

[0081] In addition, as can be seen more clearly in FIG. 4, the alignment chute part (500) is further connected to a movable support block (519a) by a bracket on which a pinion (512) is rotatably installed, and the movable support block is configured to move along a rail (519b) fixedly installed on the frame part (100), thereby enabling more stable reciprocating movement.

[0082] According to the present invention, a guide plate (600) may be further provided between the input conveyor unit (200) and the washing unit (300), and between the washing unit and the discharge conveyor unit (400) to prevent the cup lid (C1) (C2) from falling due to movement before / after washing.

[0083] In addition, a sewage tank (800) may be further provided at the bottom of the frame (100) to receive and process sewage as well as various foreign substances generated during the washing process.

[0084] The automatic washing process of the cup lid of the present invention, which is configured as described above, can be further understood by referring to FIGS. 6a to 6e.

[0085] Referring to Fig. 6a, when the cup lid (C1) before washing is fed into the upper part of the washing tube (310) through the alignment chute (500), the lower part of the cup lid (C1) before washing is supported by the brush (338c) provided in the support head (338) of the lower washing part (330) that is moved upward by the operation of the motor (M4).

[0086] Through the process of FIG. 6a, the cup lid (C1) before washing, which is supported by the brush (338c) provided on the support head (338) of the lower washing unit (330), is moved by the lower washing unit (330) which is moved downward by the motor (M2) as shown in FIG. 6b, so that its side part is moved to the washing operation position, i.e., the position of the washing liquid spray nozzle (312).

[0087] When the side of the cup lid (C1) before washing is lowered to the washing position through the process of FIG. 6b, as shown in FIG. 6c, the upper washing part (320) is lowered by the motor (M2) and the brush (326c) provided as the support head (326) is brought into close contact with the upper surface of the cup lid before washing, and at the same time, the brush (338c) provided on the support head (338) of the lower washing part (330) and the brush (326c) provided on the support head (326) of the upper washing part (320) are rotated in opposite directions by the motor (M5) and the motor (M3), respectively, so that the lower and upper surfaces of the cup lid (C1) before washing are first evenly washed using the cleaning liquid sprayed through the cleaning liquid spray nozzle (312).

[0088] In addition, in the washing process of FIG. 6c, the cup lid (C1) before washing is washed while the brushes (338c) (326c) provided on the support heads (338) (326) of the lower and upper washing parts (330) (320) rotate in opposite directions, so that the washing process is performed while remaining in place without following one side, so that the washing process for the upper and lower parts can be performed very stably and evenly.

[0089] When the lower and upper surfaces of the cup lid (C1) before washing are washed through the washing process of Fig. 6c, the supply of the washing liquid through the washing liquid spray nozzle (312) is stopped as shown in Fig. 6d, and the brush (338c) provided on the support head (338) of the lower washing part (330) and the brush (326c) provided on the support head (326) of the upper washing part (320) are rotated in the same direction by the motor (M5) and the motor (M3), respectively, to evenly wash the side surface of the cup lid before washing a second time using the washing liquid sprayed through the washing liquid spray nozzle (313).

[0090] In addition, in the washing process of FIG. 6d, when washing the side of the cup lid (C1) before washing, the upper and lower parts of the cup lid (C1) before washing are rotated together in the same direction while being in close contact with each other by the respective brushes (338c) (326c) provided on the support heads (338) (326) of the lower and upper washing parts (330) (320), so that the side parts are washed by the washing water sprayed through the washing water spray nozzle (314), thereby enabling stable and even washing of the side parts.

[0091] When the side of the cup lid (C1) before washing is completed through the process of FIG. 6d, the upper washing part (320) is raised by the motor (M2) and returned to its original position as shown in FIG. 6e, and the lower washing part (330) is raised by the motor (M4) more than the washing position and moved so that the lower end of the cup lid (C2) after washing, which is supported by the brush (338c) of the support head (338), is exposed to at least the upper end of the washing tube (310).

[0092] Through the above processes, when the washing of the cup lid (C1) before washing is completed and at the same time, the cup lid (C2) after washing is raised to be exposed to the upper part of the washing pipe (310), the cup lid (C2) after washing exposed to the upper part of the washing pipe is ejected to the discharge conveyor part (400) by the eject part (520) of the alignment chute part (500) that moves to supply the cup lid before washing, which is aligned and arranged again in the chute part (510), to the upper part of the washing pipe (310) of the washing part (300). The supply and discharge process of the cup lid before / after washing to the washing part (300) using the alignment chute part (500) may be referred to FIGS. 1A and 1B.

[0093] Meanwhile, each of the support heads (326)(338) of the upper and lower washing parts (320)(330) that move up and down to support and wash the cup lid (C1) before washing is elastically operated by itself by each elastic member (326a)(338a) that is elastically installed between the rotating tube (325)(337), so that the brushes (326c)(338c) provided on each of the support heads (326)(388) can elastically come into close contact while appropriately responding to the shape of the lower surface, upper surface, or side surface of the cup lid (C1) before washing.

[0094] Accordingly, the present invention arranges the cup lid (C1) before washing, which is moved through the input conveyor (200), in the chute (510) of the alignment chute (500), and automatically inputs the cup lid (C1) before washing into the washing pipe (310) of the washing unit (300) while reciprocating the alignment chute with respect to the washing unit (300) so that washing is evenly performed through the upper and lower washing units (320)(330), and at the same time, the cup lid (C2) after washing is automatically ejected to the discharge conveyor unit (400) through the eject unit (512) when the alignment chute (500) moves to the washing unit (300), thereby automatically performing the washing operation, thereby enabling continuous and repetitive washing of the cup lid, and thereby providing high washing efficiency and workability.

[0095] According to the present invention, the washing operation of the cup lid can be performed very safely and efficiently because each working condition is set in advance through the control unit (700).

[0096] Meanwhile, various motors applied to the automatic washing system of the reusable cup lid of the present invention may have a structure capable of unidirectional or forward / reverse rotation depending on their function.

[0097] Meanwhile, according to the present invention, the upper and lower washing parts (320) (330) constituting the washing part (300) can be variously modified depending on the shape or form of the upper and lower parts of the cup lid that requires washing, and when describing the upper and lower washing parts (320) (330) of the present invention that are variously modified, the same components will be described by assigning the same drawing reference numerals as the components before modification, and similar components will be described by assigning similar drawing reference numerals to help understand the description. In particular, for the sake of convenience of description, redundant descriptions of the components and operational effects of the same components may be omitted. In addition, when describing modified embodiments, although description is given with a focus on FIG. 7, it is natural that the descriptions of the components and operational relationships illustrated in FIGS. 1A, 1B, 2 to 5 are sufficiently cited and referenced.

[0098] According to the present invention, the upper and lower washing parts (320) (330) can be modified as shown in Fig. 7. The upper washing part (320) and the lower washing part (330) of the modified embodiment basically have the same lifting and lowering and washing structures as the structure before the modification, and provide the same operational effect.

[0099] However, as can be seen in Fig. 7, the upper washing part (320) that is subjected to deformation has only a difference in the degree to which the shape of the brush (1326c) provided on the support head (326) is formed to match the shape or space of the upper washing part of the cup lid (C1) before washing, and in consideration of this, a detailed description thereof is omitted.

[0100] In addition, the lower washing part (330) can be modified to fit the shape or space of the lower part of the cup lid (C1) before washing in terms of the configuration of the support head (338) and the shape of the brush provided thereon, and further, a separate ejector piece (1338g) and a brush (1338g-1) are further provided thereon to move the washed cup lid (C2) upward, and a lifting and lowering blocking means for forcibly controlling the lifting and lowering movement of the support head according to the ejection operation of the support head is further provided in the washing pipe (310). The modified lower washing part (330) configuration will be described in more detail below.

[0101] Referring to FIG. 7, the support head (338) of the lower washing section (330) to be deformed is fixedly installed on the support head shaft (338a) and has first and second movable plates (1338a) (1338b), one or more lifting and lowering support rods (1338c) interposed between the first and second movable plates, with the upper end fixed to the second movable plate (1338b) and the lower end penetrating through the first movable plate (1338a), and an elastic member (1338d) elastically installed on the outside of the lifting and lowering support rods (1338c) interposed between the first and second movable plates (1338a) (1338b), and a fixed support rod (1338e) penetratingly supported by the first movable plate, the lower end of which is fixedly supported and at the same time the upper end of which is fixedly supported by the second movable plate (1338b). It is composed of an ejection piece (1338g) that is penetrated to be raised and lowered with respect to a through hole (1338f), and an elastic member (1338h) interposed on the outside of a fixed support bar arranged between the upper part of the first movable plate and the lower part of the ejection piece (1338g) to elastically support the ejection piece, and a brush (1338b-1) (1338g-1) for safely supporting and washing the entire lower part of the cup lid before washing is respectively provided on the upper part of each of the second movable plate (1338b) and the ejection piece (1338g), and the support head (338) can be configured so that, when the second movable plate (1338b) is raised and lowered, excessive lifting movement is prevented by a lifting blocking piece (1316) provided inside the washing pipe (310).

[0102] The lower washing part (330) of the above configuration washes the cup lid before washing by operating as shown in FIGS. 8a to 8e due to the structure of the support head (338) that is being deformed. This will be examined in more detail as follows.

[0103] Referring to Fig. 8a, the lower part of the cup lid (C1) before washing, which is moved to the upper part of the washing tube (310) of the washing unit (300) by the alignment chute (500), is supported by a brush (1338g-1) provided on the ejector piece (1338g) of the lower washing unit (330) that is moved upward by the operation of the motor (M4). At this time, the second movable plate (1338b) of the support head (338) is forcibly prevented from rising excessively by the lifting blocking piece (1316) provided inside the washing pipe (310), and only the ejection piece (1338g) fixedly supported by the fixed support rod (1338e) for the first movable plate (1338a) is guided to the lifting support rod (1338c) so that the first movable plate (1338a) is supported while being separately raised further through the through hole (1338f) of the first movable plate (1338a) while compressing the elastic member (1338d).

[0104] When the lower part of the cup lid (C1) before washing is supported by the ejector piece (1338g) through the process of FIG. 8a, as shown in FIG. 8b, the ejector piece is moved downward together with the support head (338) of the washing part (330) while the lower part of the cup lid (C1) before washing is supported, but is lowered so that the side part of the cup lid (C1) before washing moves to the washing position, that is, to the position of the cleaning solution spray nozzle (312).

[0105] Through the process of FIG. 8b, when the side of the cup lid (C1) before washing is moved to the washing position, as shown in FIG. 8c, the upper washing part (320) is moved downward by the motor (M2), and the brush (1326c) provided as the support head (326) is brought into close contact with the upper surface of the cup lid before washing, and at the same time, the brushes (338b-1) (1338g-1) provided on the second movable plate (1338b) and the eject piece (1338g) of the support head (338) constituting the lower washing part (330) are rotated in opposite directions by the motor (M5), and the brush (1326c) provided on the support head (326) of the upper washing part (320) is rotated in opposite directions by the motor (M3), so that the lower and upper surfaces of the cup lid (C1) before washing are evenly washed for the first time using the cleaning liquid sprayed through the cleaning liquid spray nozzle (312). It works.

[0106] In addition, in the washing process of FIG. 8c, the cup lid (C1) before washing is washed while the brushes (338b-1) (1338g-1) (1326c) provided on the support heads (338) (326) of the lower and upper washing parts (330) (320) rotate in opposite directions, so that the washing process is performed while remaining in place without following one side, so that the washing process for the upper and lower parts can be performed very stably and evenly.

[0107] When the lower and upper surfaces of the cup lid (C1) before washing are washed through the washing process of Fig. 8c, the supply of the washing liquid through the washing liquid spray nozzle (312) is stopped as in Fig. 8d, and the brushes (338b-1) (1338g-1) provided on the second movable plate (1338b) and the ejector piece (1338g) of the support head (338) constituting the support head (338) of the lower washing unit (330) are rotated in the same direction by the motor (M5), and the brush (1326c) provided on the support head (326) of the upper washing unit (320) is rotated in the same direction by the motor (M3), thereby evenly washing the side surface of the cup lid before washing for the second time.

[0108] In addition, in the washing process of FIG. 8d, when washing the side of the cup lid (C1) before washing, the upper and lower parts of the cup lid (C1) before washing are in close contact with each other by the respective brushes (338b-1) (1338g-1) (1326c) provided on the support heads (338) (326) of the lower and upper washing parts (330) (320), and while rotating together in the same direction, washing is performed on the side by the washing water sprayed through the washing water spray nozzle (314), so that even washing of the side can be stably performed.

[0109] When the washing of the side of the cup lid (C1) before washing is completed through the process of FIG. 8d, the upper washing part (320) is lifted by the motor (M2) as shown in FIG. 8e and returned to its original state, and the support head (338) of the lower washing part (330) that is lifted by the motor (M4) is lifted together with the first and second movable plates (1338a) (1338b) to a certain position, and at some point, the first movable plate (1338a) is prevented from rising by the lifting blocking member (1316) provided inside the washing pipe (310), and at this time, only the second movable plate (1338b) is lifted, and at the same time, the ejection member (1338g) is lifted separately through the through hole (1338f) formed in the first movable plate (1338a) and the washed cup lid (C2) that is partially supported on the upper part thereof is lifted by the washing pipe (310). It is moved upward, and the elastic member (1338h) interposed between the second movable plate (1338b) and the fixed support bar (1338e) exerts an appropriate elastic compression action.

[0110] Through processes such as those in FIGS. 8a to 8e, when the washing of the cup lid (C1) before washing is completed and at the same time the cup lid (C2) after washing is raised to be exposed to the upper part of the washing pipe (310), the cup lid (C2) after washing exposed to the upper part of the washing pipe is ejected to the discharge conveyor part (400) by the eject part (520) of the alignment chute part (500) that moves to supply the cup lid before washing, which is aligned and arranged again in the chute part (510), to the upper part of the washing pipe (310) of the washing part (300). The supply and discharge process of the cup lid before / after washing to the washing part (300) using the alignment chute part (500) described above may be referred to FIGS. 1a and 1b.

[0111] Meanwhile, each of the supporting heads (326)(338) of the upper and lower washing sections (320)(330) that move up and down to support and wash the cup lid (C1) before washing is elastically operated by itself by the elastic members (326a)(338a) elastically installed between the rotating tube (325)(337), the elastic members (1338d) elastically installed on the lifting and lowering support rod (1338c), and the elastic members (1338h) elastically installed on the fixed support rod (1338e), so that the brushes (1326c)(1338b-1)(1338g1) provided on each of the supporting heads (326)(388) can elastically come into close contact while appropriately responding to the shape of the lower surface, upper surface, and side surface of the cup lid (C1) before washing.

[0112] Accordingly, even if the structure of the support head (338) of the lower washing section (330) is modified as described above, the cup lid before washing is automatically aligned by the alignment chute section (500) and moved to the washing section (300), and the upper and lower washing sections (320) (330) of the washing section (300) are used to selectively spray the washing liquid and washing water on the upper and lower parts and the side parts of the cup lid before washing and are sequentially washed, and the cup lid (C2) that has been washed in the washing section is moved to the upper part of the washing pipe (310), and the washed cup lid that has been raised to the upper part of the washing pipe (310) is dropped and discharged to the discharge conveyor section (400) by the eject section (520) of the alignment chute section (500), thereby enabling a continuous and repetitive washing operation to be automatically performed.

[0113] In addition, according to the present invention, the washing pipe (310) and the upper and lower washing sections (320) (330) constituting the washing section (300) may be modified in other ways as illustrated in FIG. 9. When describing the upper and lower washing sections (320) (330) of the present invention that are modified in various ways, the same components may be described with the same drawing references as the components before modification, and similar components may be described with similar drawing references to help with the understanding of the description. In particular, for the sake of convenience of description, redundant descriptions of the components and operational effects of the same components may be omitted. In addition, when describing modified embodiments, although reference is made primarily to FIG. 9, it is natural that the descriptions of the components and operational relationships illustrated in FIGS. 1A, 1B, 2 to 5 are sufficiently cited and referenced.

[0114] Referring to FIG. 9, the upper washing section (320) and the lower washing section (330) of the washing section (300) that are modified differently have basically the same rising and falling structure compared to the structure before modification, and are modified to a structure that simultaneously cleans the upper and lower parts and the side parts by spraying only washing water without using a cleaning solution during washing, and there is a difference in the degree of modification of the structure that pressurizes the upper surface of the cup lid before washing using the upper fixing jig and supports it with the lower washing section, and these differences will be described in more detail below.

[0115] Referring to Fig. 9, a washing pipe (310) that is also modified differently is provided with washing water spray nozzles (313) (2313a) for spraying washing water according to washing of the side and bottom of the cup lid (C1) before washing, each of which is provided at an appropriate spray position.

[0116] In addition, the upper washing part (320) is configured to include a movable frame (321), a first support block (322) fixed to the fixed support bar (111) of the frame part (100) for vertically penetrating the movable frame to operate the movement of the movable frame, and at the same time, a lower end of the lifting support shaft (323) fixedly supported on the movable frame (321) and operated to move up and down by the forward and reverse rotation of the motor (M2), a support head shaft (2326a) disposed on the same vertical axis (P1) as the washing pipe (310) so as to be able to move up and down together with the movable frame (321) and having one end penetratingly fixed, and a support head (2326) having one end fixedly installed to the other end of the support head shaft, and a rotation guide block (2326c) having a bearing (2326b) installed therein is fixedly installed at the lower end of the support head, and the bearing The support shaft (2326d) may be rotatably supported through a penetrating support, and an upper fixing jig (2326e) for fixing the upper portion of the cup lid (C1) before washing may be provided at one end of the support shaft, and a washing water spray nozzle (2326f) for spraying washing water on the upper surface of the cup lid (C1) before washing may be provided at the lower portion of the support head.

[0117] An elastic member (2326g) can be installed more elastically on the outside of the support shaft (2326d) exposed through the lower portion of the support head (326) and the upper portion of the upper fixing jig (2326e), and through this, it is possible to provide an appropriate elastic pressure when applying pressure to the upper surface of the cup lid (C1) before washing using the upper fixing jig.

[0118] In addition, the lower washing section (330) of another modified embodiment is vertically installed between the movable frame (331) and the upper and lower brackets (B2) (B3) provided on one side of the frame to move the movable frame up and down, and has one side connected to the motor (M4) and the other side rotatably supported by the lifting and lowering guide pipe (332) fixedly installed on the movable frame, a guide rod (335) vertically supported by the second support block (334) fixedly supported by the bracket (B3) arranged at the lower end of both sides of the movable frame to induce stable lifting and lowering of the movable frame, and a rotary tube (337) rotatably supported by the rotary guide block (336) fixedly installed on the movable frame (331) so as to be arranged on the same vertical axis (P1) as the washing pipe, and a support head shaft (338a) provided inside the rotary tube. A support head (338) is provided with a support plate (2338) that supports the lower surface of a cup lid (C1) before washing, and is fixedly installed to be walked on by a guide pin (338b) in a guide groove (337a) formed in the above-mentioned rotary tube so as to be able to rotate and move up and down, and at the same time, an elastic member (339) that is elastically installed on the outside of the support head shaft (338a) so as to be arranged between the lower part of the support head (338) and the rotary tube (337) to provide elastic force to the support head, and each support head (338) may be configured to be connected so as to be able to rotate in one direction by a motor (M5) that moves up and down together with the movable frame (331).

[0119] The washing process of the cup lid before washing through the washing unit (300) configuration of the present invention, which is modified as described above, will be described with reference to FIGS. 10a to 10d as follows. Even in the case of washing using the modified washing unit (300), the cup lid (C1) before washing is automatically aligned in the chute unit (510) of the alignment chute unit (500) through the input conveyor unit (200) and moved to the washing unit (300), and the cup lid (C2) after washing in the washing unit (300) is ejected to the discharge conveyor unit (400) using the eject unit (520) of the alignment chute unit, all of which are identical to the washing unit structure before modification, and this can be described with reference to FIGS. 1a, 1b, and 2 to 4.

[0120] Referring to Fig. 10a, the lower part of the cup lid (C1) before washing, which is moved to the upper part of the washing pipe (310) of the washing unit (300) by the alignment chute (500), is supported by the support plate (2338) provided on the support head (338) of the lower washing unit (330) that is moved upward by the operation of the motor (M4).

[0121] When the lower part of the cup lid (C1) before washing is supported by the support piece (2338) of the support head (338) through the process of FIG. 10a, as shown in FIG. 10b, the support head (338) of the lower washing part (330) is lowered by the operation of the motor (M4) so ​​that the side part of the cup lid (C1) before washing is moved to the washing position, that is, to the position of the cleaning solution spray nozzle (312) while the lower part of the cup lid (C1) before washing is supported.

[0122] Through the process of FIG. 10b, the side of the cup lid (C1) before washing is moved to the washing position, and as shown in FIG. 10c, the upper washing part (320) moves downward by the motor (M2) and the upper surface of the cup lid before washing is closely supported by the upper fixing jig (2326c) equipped with the support head (326), and the support head (338) of the lower washing part (330) is rotated in one direction by the motor (M5). Then, at this time, the cup lid (C1) before washing is also pressed against the upper fixing rib (2326c) whose upper surface is rotated by the support shaft (2326d) with respect to the support head (326) of the upper washing part (320), so that the upper and lower surfaces and the side surfaces are washed simultaneously by the washing water sprayed through the washing water spray nozzles (312)(2313)(2326f) while rotating together.

[0123] When the simultaneous washing of the upper and lower parts and the side parts of the cup lid (C1) before washing is completed through the process of FIG. 10c, the upper washing part (320) is raised by the motor (M2) and returned to its original state as shown in FIG. 10d, and the support head (338) of the lower washing part (330) is raised by the motor (M4) to raise the washed cup lid (C2) supported on the upper part of the support plate (2338) to the upper part of the washing pipe (310).

[0124] Through processes such as those in FIGS. 10a to 10d, when the washing of the cup lid (C1) before washing is completed and at the same time, the cup lid (C2) after washing is raised to be exposed to the upper part of the washing pipe (310), the cup lid (C2) after washing exposed to the upper part of the washing pipe is ejected to the discharge conveyor part (400) by the eject part (520) of the alignment chute part (500) that moves to supply the cup lid before washing, which is aligned and arranged again in the chute part (510), to the upper part of the washing pipe (310) of the washing part (300). The supply and discharge process of the cup lid before / after washing to the washing part (300) using the alignment chute part (500) described above may be referred to FIGS. 1a and 1b.

[0125] Meanwhile, the support head (338) of the lower washing part (330) that moves up and down to support and wash the cup lid (C1) before washing is elastically operated by each elastic member (338a) elastically installed between the rotating tube (337), so that it can be elastically supported while appropriately responding to the shape of the lower part of the cup lid (C1) before washing.

[0126] In addition, in the case of the configuration of the washing unit (300) that is modified as described above, in particular, the cup lid before washing is supported by the support head (338) of the lower washing unit (330) and is pressurized with an appropriate elastic pressure by the upper fixing jig (2326e) of the upper washing unit (320) that is provided to be rotatable, and while simultaneously rotating along the rotational direction of the lower washing unit (330), the upper and lower parts and the side parts can be quickly washed simultaneously by the washing water sprayed through each washing water spray nozzle (313)(2313)(2326f).

[0127] Accordingly, even if the washing structure of the upper washing section (320) and the lower washing section (330) constituting the washing section (300) is modified as described above, the cup lid before washing is automatically aligned by the alignment chute section (500) and moved to the washing section (300), and the upper and lower washing sections (320) and (330) of the washing section (300) are used to sequentially wash the upper and lower parts and the side parts of the cup lid before washing while selectively spraying the washing liquid and the washing water, and the cup lid (C2) that has been washed in the washing section is moved to the upper part of the washing pipe (310), and the washed cup lid that has been raised to the upper part of the washing pipe (310) is dropped and discharged to the discharge conveyor section (400) by the eject section (520) of the alignment chute section (500), thereby automatically performing a continuous and repetitive washing operation.

[0128] Although the present invention has been described with reference to the attached drawings, it is to be understood that the present invention is not limited thereto and that many modifications and changes may be made without departing from the scope of the following claims.
