Description

Infusion bag packaging envelope vacuum packaging system

Technical Field

The present invention relates to an infusion bag package envelope vacuum packaging system that packages a package envelope for packaging an infusion bag or the like in a vacuum state, and more particularly, to an infusion bag package envelope vacuum packaging system that can rapidly package a package envelope for protecting an infusion bag from being damaged by external impact during circulation in a vacuum state.

Background

In general, an infusion bag is a container made of a flexible material, and saline, glucose, nutrient solution, distilled water, and the like can be put into the interior thereof and sealed to be kept in a state isolated from the outside, so that it is less fragile than a conventional glass bottle and is convenient to use and discard, thereby being widely used.

The infusion bag is commercialized through a process of filling an infusion solution in a process of storing the infusion solution. The infusion bag is flat before filling with the infusion solution, and in the filling step, in order to inject the infusion solution into the interior, the inlet should be placed upward, and before that, it is necessary to arrange the individual infusion bags in order and supply them continuously.

In order to safely protect the infusion bag, the plastic sheet is put into the bag, and then the plastic sheet is sealed to exclude moisture and the like, thereby completing the packaging operation of the infusion bag.

However, since the above-described operation of packaging the infusion bag requires an operator to manually complete each process, the efficiency of packaging the infusion bag is extremely low, and in particular, the operator directly puts the infusion bag into the plastic sheet, which causes entry of impurities and the like, and thus, there is a disadvantage that the product hygiene is deteriorated.

In addition, air remains in the space between the infusion bag and the plastic sheet, so that water is generated between the infusion bag and the plastic sheet due to the temperature difference between the infusion bag and the outside in the circulation process, and the problem that a user of the infusion bag is stained with water when removing the plastic sheet wrapping the infusion bag may occur.

Each member will be described in more detail with reference to the accompanying drawings.

Referring to fig. 1 to 5, the vacuum packaging system for packaging envelopes of infusion bags of the present invention comprises a first conveyor 710, a second conveyor 720 and a lathe 730.

The first conveyor 710 has a structure for conveying the infusion bag entering the front end to the rear end, and may include a linear belt having an endless track and a servo motor for driving the linear belt. At this time, the width of the linear belt is greater than the length of the infusion bag, and the surface of the linear belt is provided with a plurality of partition plates for dividing the space of the linear belt, so that the infusion bags are conveyed in a state of keeping a certain interval.

The second conveyor 720 has a structure adjacent to the first conveyor 710 and arranged in parallel to convey the infusion bag entering the front end to the rear end, and may include a linear belt having an endless track and a servo motor driving the linear belt. At this time, the width of the linear belt is larger than the length of the infusion bag.

The lathe 730 provides an installation space for the packing envelope pickup unit 500 that transfers the packing envelopes stacked in the packing envelope housing box 400 to the packing envelope conveying unit 300, and any lathe may be used as long as such an object can be achieved.

Preferably, such a lathe 730 is disposed in the opposite direction of the first conveyor 710 centering on the second conveyor 720 as shown in fig. 1.

Referring to fig. 1 and 2, the vacuum packaging system for packaging envelopes of infusion bags of the present invention may further include

inlet conveyors

810 and 820 and a pick-up unit 830 for an aligning conveyor.

The

inlet conveyors

810 and 820 are disposed adjacent to and in parallel with the first conveyor 710, and convey the infusion bag entering the front end to the rear end, and include a detection conveyor 810 having a section for detecting the infusion bag and an alignment conveyor 820 for aligning the infusion bag passing through the detection conveyor 810.

The inspection conveyor 810 is a rotating belt having an endless track, which uses a transparent polyurethane belt so that the state of the infusion bag can be easily observed during the conveyance. As required, an infusion bag discrimination device 812 may be provided on the inspection conveyor 810 to automatically discriminate a defective infusion bag by photographing the infusion bag.

The aligning conveyor 820 is provided with an aligning stopper so that the infusion bags having passed through the sensing conveyor 810 are aligned at certain intervals to be conveyed. At this time, the arrangement stopper is provided at the front end of the arrangement conveyor 820 adjacent to the rear end of the inlet conveyor, and is composed of an infusion bag stop cylinder connected to the control board, and a movement blocking rod connected to the infusion bag stop cylinder and entering the movement path of the infusion bag according to the driving of the infusion bag stop cylinder.

Such inspection conveyor 810 and alignment conveyor 820 are either formed of a single linear belt having an endless track, or separate linear belts.

The picking unit 830 for the aligning conveyor may be any picking device as long as it can suck and convey a plurality of infusion bags conveyed to the rear end of the aligning conveyor 820 to the front end of the first conveyor 710.

For example, the pick-up unit 830 for an alignment conveyor includes a lifting body that can be moved up and down by driving a pneumatic cylinder, and an adsorption head that is provided at a lower end of the lifting body and vacuum-adsorbs an infusion bag.

Specifically, the pick-up unit 830 for the aligning conveyor has six suction heads to suck six infusion bags at a time and then moves the infusion bags to the front end of the first conveyor 710 so that the subsequent processes are performed regardless of the moving speed of the infusion bags conveyed by the entrance conveyor.

The operation of the pick-up unit 830 for the aligning conveyor is electrically and mechanically controlled by a controller of a control panel.

Referring to fig. 1 to 5, the vacuum packaging system for packaging envelopes of infusion bags of the present invention comprises an infusion bag pickup unit 100.

The bag pickup unit 100 may use any pickup device as long as it can pick up the bag that has entered in the aligned state by the first conveyor 710.

For example, the infusion bag pickup unit 100 includes an elevating body 110 that can be moved up and down by driving a pneumatic cylinder, and an adsorption head 120 that is provided at a lower end portion of the elevating body 110 and vacuum-adsorbs an infusion bag.

Specifically, the infusion bag pickup unit 100 has six suction heads as shown in fig. 3 and 4, sucks six infusion bags at a time, picks up the infusion bags to be spaced apart from the first conveyor 710, and feeds the infusion bags to the infusion bag conveying unit 200 near the lower portion of the suction heads.

The operation of such an infusion bag pickup unit 100 is controlled electrically and mechanically by the controller of the control panel.

Referring to fig. 1 to 5, the vacuum packaging system for packaging envelopes of infusion bags of the present invention includes an infusion bag conveying unit 200.

The infusion bag feeding unit 200 has an infusion bag feeding plate 232 on which an infusion bag picked up by the infusion bag pickup unit 100 is placed, so that the infusion bag feeding plate 232 is reciprocated between the second conveyor 720 and the first conveyor 710, thereby feeding the infusion bag to the second conveyor 720 provided at the side of the first conveyor 710.

In an embodiment, the infusion bag feeding unit 200 of the present invention includes a first guide frame 212, a second guide frame 214, a rotating frame 220, an auxiliary frame 230, and an infusion bag driving unit.

Specifically, the first guide frame 212 and the second guide frame 214 are provided at a distance from each other on the first conveyor 710 located at the lower portion of the infusion bag pickup device, and provide a moving path of the rotating frame 220.

The rotating frame 220 is disposed between the first guide frame 212 and the second guide frame 214, and performs a reciprocating linear motion along a moving path formed by the first guide frame 212 and the second guide frame 214. For example, the rotating frame 220 is positioned in the direction of the second conveyor 720 in a state where the infusion bag pickup unit 100 does not suck the infusion bag conveyed by the first conveyor 710, and when the infusion bag pickup unit 100 sucks the infusion bag conveyed by the first conveyor 710 to pick up, the rotating frame 220 moves in the direction of the first conveyor 710, as shown in fig. 6.

The auxiliary frames 230 are provided at the rotating frame 220 at regular intervals along the length direction of the rotating frame 220 corresponding to the respective suction heads of the infusion bag pickup unit 100, and have infusion bag feeding plates 232 having a size smaller than that of the infusion bags at the ends thereof. Such an auxiliary frame 230 transfers the infusion bag placed on the infusion bag transfer plate 232 to the second conveyor 720 according to the movement of the rotating frame 220. At this time, the reason why the size of the infusion bag feeding plate 232 is smaller than the size of the infusion bag is to separate the infusion bag feeding plate 232 from the infusion bag in a state where the frame portion of the infusion bag separated from the infusion bag feeding plate 232 is pressed.

As shown in fig. 6, when the infusion bag pickup unit 100 picks up the infusion bag transferred by the first conveyor 710 by suction, the auxiliary frame 230 moves to the first conveyor 710 along the rotating frame 220 moving in the direction of the first conveyor 710, and is positioned at the lower portion of the suction head 120 of the infusion bag pickup unit 100.

Also, the number of the auxiliary frames 230 is preferably the same as the number of the suction heads of the infusion bag pickup unit 100. For example, if the bag pickup unit 100 has six suction heads, the rotating gantry 220 has six auxiliary gantries 230.

The infusion bag driving part is coupled to the rotating frame 220 to rotate the rotating frame 220 through the first guide frame 212 and the second guide frame 214, and may include a pneumatic cylinder, a hydraulic cylinder, a driving motor, or the like.

The operation of the infusion bag drive unit is electrically and mechanically controlled by a controller of a control panel.

Referring to fig. 1 to 5, the vacuum packaging system for packaging envelopes of infusion bags of the present invention includes a packaging envelope conveying unit 300.

In order to allow the packaging envelope to accommodate the bag feed plate 232 rotated to the upper portion of the second conveyor 720, the packaging envelope conveying unit 300 conveys the packaging envelope from a lathe 730 provided at the side of the second conveyor 720 to the bag feed plate 232 positioned at the upper portion of the second conveyor 720 to convey the packaging envelope away from the second conveyor 720 at the inlet side of the packaging envelope. At this time, the infusion bag conveyed to the upper part of the second conveyor 720 by the infusion bag conveying plate 232 is positioned at a position spaced apart from the second conveyor 720 as shown in fig. 7, and the infusion bag can be accommodated in the packaging envelope by moving the packaging envelope in the infusion bag direction.

As a specific embodiment, the packing envelope conveying unit 300 of the present invention includes a plurality of right and left pressing bars 310, a first driving mechanism, a packing envelope conveying bar 320, a fixed guide 330, and a second driving mechanism.

The right and left pressing rods 310 press the wrapping envelopes, which are conveyed to the upper portion of the lathe 730 by the wrapping envelope picking unit 500, in the right and left directions from both inner side surfaces, and in order to smoothly enter the inside of the wrapping envelopes through the entrances of the wrapping envelope picking units 500 while the wrapping envelopes approach the wrapping envelope picking units 500, the wrapping envelopes are kept in a contracted state, and then are unfolded in the right and left directions while the entrances of the wrapping envelopes are kept open as the wrapping envelope picking units 500 move into the inside of the wrapping envelopes.

Specifically, as shown in fig. 5, the left and right pressurizing rods 310 are provided on the left and right sides, respectively, and are composed of a pair of support rods that are brought into close contact with each other or spaced apart from each other by the driving of the first driving mechanism. At this time, it is preferable that the maximum spaced distance of any of the first support bars 312 from the second support bar 134 is less than the left-right width of the packing envelope B of 1 to 3 cm. This is to pull the wrapping sheet from both inner side surfaces in the left-right direction in a state where the left and right pressing bars 310 are spaced apart from each other, so that the entrance of the wrapping sheet B is kept in a maximum state.

The number of the left and right pressing rods 310 is preferably the same as the number of the auxiliary frames 230 of the infusion bag feeding unit 200. For example, if the infusion bag feeding unit 200 has six suction heads, the packing envelope feeding unit 300 has six right and left pressing rods 310.

The first driving mechanism is connected to each of the left and right pressurizing rods 310, respectively, to expand or contract each of the left and right pressurizing rods 310 leftward and rightward, and may include a pneumatic cylinder, a hydraulic cylinder, a driving motor, or the like. In this case, the first driving mechanism is provided in a number corresponding to the number of the left and right pressurizing rods 310, or is provided in a single one and connected to all the left and right pressurizing rods.

The wrapping envelope conveying rod 320 provides a space in which a plurality of left and right pressing rods 310 are disposed at regular intervals, and reciprocates between the lathe 730 and the second conveyor 720, whereby the wrapping envelopes can be conveyed from the lathe 730 to the second conveyor 720 by the respective left and right pressing rods 310.

The fixed guide 330 is disposed on the second conveyor 720 or the lathe 730 to provide a moving path of the wrapping sheath transfer rod 320, and linearly reciprocates between the second conveyor 720 and the lathe 730.

The second driving mechanism, which is provided between the packaging envelope conveying rod 320 and the fixed guide 330 to move the packaging envelope conveying rod 320, may include a pneumatic cylinder, a hydraulic cylinder, a driving motor, or the like. At this time, the second driving mechanism provides power for reciprocating the fixed guide 330 between the second conveyor 720 and the lathe 730.

In order to allow the right and left pressing bars 310 to be smoothly accommodated by the packing envelopes transferred to the upper portion of the lathe 730, the packing envelope transferring unit 300 has air nozzles provided at the right and left pressing bars 310 to discharge air to inlets of the packing envelopes introduced into the right and left pressing bars 310 by the packing envelope picking unit 500, as required.

Fig. 8 is a schematic diagram for explaining the infusion bag pressurizing unit and the infusion bag feeding unit of the present invention. Referring to fig. 8, the vacuum packaging system for packaging envelopes of infusion bags of the present invention may further include an infusion bag pressurizing unit 900.

The infusion bag pressurizing unit 900 is provided in the second conveyor 720 and pressurizes the infusion bag and the packaging envelope exposed to the outside of the infusion bag conveying plate 232 in the direction of the mounting surface of the second conveyor 720 on which the packaging envelope is mounted, and pressurizes the infusion bag and the packaging envelope exposed to the outside of the infusion bag conveying plate 232 in the direction of the second conveyor 720 in order to separate the infusion bag and the packaging envelope simultaneously in the process that the infusion bag conveying plate 232 rotated to the upper portion of the second conveyor 720 and accommodated in the packaging envelope together with the infusion bag is moved to the first conveyor 710.

Specifically, the infusion bag pressurizing unit 900 includes: a fixing frame disposed on a side surface and an upper surface of the second conveyor 720; and a pneumatic cylinder 920 installed at a fixed frame of the second conveyor 720 and lifting a piston rod 922 according to the movement of the rotary frame 220. An elastic pad 924 formed of silicon rubber or the like is formed at the end of the piston rod 922 as needed to protect the infusion bag from damage.

As described above, if the infusion bag pressurizing unit 900 pressurizes the infusion bag and the packaging envelope in the direction of the second conveyor 720 before the infusion bag transport plate 232 moves to the first conveyor 710, even if friction is generated between the infusion bag transport plate 232 and the infusion bag, the movement of the infusion bag is restricted and the infusion bag does not come off the inside of the packaging envelope.

Referring to fig. 1 to 5, the vacuum packaging system for packaging envelopes of infusion bags of the present invention includes a packaging envelope storage box 400.

The package envelope storage box 400 is provided on a side surface of the lathe 730 to provide a storage space in which the package envelopes can be stored in a stacked state, and is preferably provided in a direction opposite to the second conveyor 720 with the lathe 730 as a center. At this time, a plurality of receiving spaces are formed along the longitudinal direction of the packing envelope housing box 400.

Referring to fig. 1 to 5, the vacuum packaging system for packaging envelopes of infusion bags of the present invention includes a packaging envelope pickup unit 500.

The package envelope pickup unit 500 may be any pickup device as long as it can achieve the above-described object by sucking the package envelope positioned at the uppermost end of the package envelope accommodating box 400 and transferring the package envelope to the package envelope conveying unit 300 which rotates to the upper portion of the lathe 730.

The wrapping cover pickup unit 500 is mounted on a fixed frame on the side and upper surface of the lathe 730 and reciprocates between the lathe 730 and the wrapping cover storage box 400.

For example, the packing envelope picking unit 500 includes: a lifting body driven by a pneumatic cylinder to move up and down; and a suction head positioned at a lower end portion of the elevating body and vacuum-sucking an upper surface of the uppermost packing envelope of the packing envelope accommodating box 400.

Specifically, as shown in fig. 4 and 6, the wrapping envelope pickup unit 500 has six suction heads to suck six wrapping envelopes at a time, and then moves the wrapping envelopes to the upper portion of the lathe 730 so that the wrapping envelopes can be inserted into the left and right pressing bars 310 of the wrapping envelope conveying unit 300 through the entrances of the wrapping envelopes.

The operation of such a packing envelope picking unit 500 is electrically and mechanically controlled by a controller of the control panel.

Referring to fig. 4 and 6, the infusion bag packing envelope vacuum packing system of the present invention includes a vacuum sealing unit 600.

The vacuum sealing unit 600 is disposed on the second conveyor 720, and after the infusion bag is accommodated in the second conveyor 720, the vacuum sealing unit contacts the packaging envelope conveyed to the rear end by the second conveyor 720, and performs vacuum evacuation and sealing on the packaging envelope accommodating the infusion bag, so that the packaging envelope and the infusion bag are kept in a vacuum state. At this time, when the package envelope containing the infusion bag reaches the vacuum sealing unit 600, the second conveyor 720 stops rotating the linear belt having the endless track for a certain period of time, and the vacuum sealing unit 600 performs vacuum evacuation and sealing of the package envelope while the belt of the second conveyor 720 is stopped.

Specifically, the vacuum sealing unit 600 includes a support frame, an air suction pipe 610, a pressure belt 620, a cushion 630, a heat sealer 640, a sealing driving mechanism 650, and optionally, an adsorption part 660.

The support frame provides an installation space for the suction pipe 610, the pressure belt 620, the heat sealer 640, and the sealing driving mechanism 650 of the vacuum sealing unit 600, and is provided on one side surface of the second conveyor 720.

The suction unit 650 lifts the upper surface of the packing envelope to open the inlet of the packing envelope so that the suction duct 610 smoothly enters the inside of the packing envelope, is disposed adjacent to the pressing belt 620 to move up and down, and intermittently applies vacuum pressure for opening the inlet of the packing envelope. For this purpose, the suction part is connected to an external vacuum pressure generator, and one suction part is used for one package envelope. For example, the vacuum sealing unit 600 passes through four packaging envelopes at a time, and four suction portions are provided on the support frame.

Specifically, as shown in fig. 9, the adsorption part 660 includes: an adsorption driving mechanism 662 provided in the support frame to provide a driving force in the vertical direction; a suction holder 664 coupled to the suction drive mechanism 662 and moved up and down by a driving force supplied from the suction drive mechanism 662; and a suction block 666 provided on the suction holder 664, connected to the vacuum pressure generator, for sucking and lifting the upper surface of the package envelope B passing through the vacuum sealing unit.

The air suction pipe 610 moves to an inlet of a packaging cover containing an infusion bag to discharge air inside the packaging cover, and linearly reciprocates in the width direction of the second conveyor 720 under the control of the control panel. For example, when the second conveyor 720 is stopped, the air suction duct 610 moves into the packaging envelope through the inlet of the packaging envelope, and the air remaining inside the packaging envelope is discharged and then moves to the outside of the packaging envelope. Also, the suction pipe 610 is connected to the exhaust pump through a hose.

The pressure belt 620 is composed of an upper pressure belt 622 and a lower pressure belt 624, and linearly reciprocates in an up-and-down direction according to control of a control panel, and is configured to press and seal the inlet of the packing envelope up and down in a state where the air suction pipe 610 moves into the packing envelope through the inlet of the packing envelope, thereby smoothly performing vacuum exhaust by the air suction pipe 610. For example, when the suction duct 610 moves to the inside of the packaging envelope, the upper pressing belt 622 descends, and the lower pressing belt 624 ascends to contact the upper pressing belt 622. When the air suction duct 610 moves to the outside of the packaging envelope, the upper pressing belt 622 rises and the lower pressing belt 624 descends.

Even if the pressing belt 620 is provided on the side surface of the second conveyor 720 via a support frame, the entrance side of the package envelope conveyed by the second conveyor 720 is not placed on the second conveyor 720 and is separated from the side surface of the second conveyor 720, and the entrance of the package envelope can be sealed by moving up and down.

The buffer pad 630 is provided at an end of the pressurizing belt 620 contacting the packing wrapper, and seals an inlet of the packing wrapper inserted into the air suction pipe 610, so that the air suction pipe 610 is not damaged even if the inlet of the packing wrapper is sealed in a state where the air suction pipe 610 is inserted into the inlet of the packing wrapper, and is formed of urethane rubber, silicon rubber, raw rubber, or the like.

The heat sealer 640 moves to the inlet to heat the inlet when the air suction pipe 610 is separated from the inlet of the packing envelope in a state where the cushion 630 seals the inlet of the packing envelope, and seals the packing envelope in a vacuum state, and is composed of an upper heat sealer 642 and a lower heat sealer 644, and linearly reciprocates in an up-down direction according to the control of the control panel. For example, when the air suction duct 610 moves from the inside to the outside of the packaging envelope, the upper heat sealer 642 and the lower heat sealer 644 are spaced apart by being brought into contact with each other by being lifted and lowered.

Even if the heat sealer 640 is provided on the side of the second conveyor 720 by a support frame, the entrance side of the package envelope conveyed by the second conveyor 720 is not placed on the second conveyor 720 and is separated from the side of the second conveyor 720, and the entrance of the package envelope can be sealed by moving up and down.

The sealing drive mechanism 650 is coupled to the pressure belt 620 and the heat sealer 640 to move the pressure belt 620 and the heat sealer 640 in the vertical direction, and is composed of a first sealing drive mechanism that moves the pressure belt 620 in the vertical direction and a second sealing drive mechanism that moves the heat sealer 640 in the vertical direction.

Referring to fig. 4 and 6, the infusion bag packaging envelope vacuum packaging system of the present invention includes a control panel.

The control board controls a series of processes based on the infusion bag conveying unit 200, the packaging envelope conveying unit 300, the packaging envelope pickup unit 500, the vacuum sealing unit 600, and the infusion bag pressurizing unit 900 under preset conditions, and thus is connected to the infusion bag conveying unit 200, the packaging envelope conveying unit 300, the packaging envelope pickup unit 500, the vacuum sealing unit 600, and the infusion bag pressurizing unit 900.

Specifically, when the infusion bag conveyed by the first conveyor 710 in the aligned state reaches the lower part of the infusion bag pickup unit 100, the control panel controls the infusion bag pickup unit 100 to lift the infusion bag to the upper part of the first conveyor 710.

Next, after the bag pickup unit 100 lifts the bag from the first conveyor 710, the control panel controls the bag conveying unit 200 to move the auxiliary frame 230 of the bag conveying unit 200 to the lower portion of the lifted bag.

Then, the control board controls the bag pickup unit 100 to separate the bag from the bag pickup unit 100 and place the bag on the bag feeding plate 232 of the auxiliary frame 230.

Next, the control panel controls the infusion bag feeding unit 200 to feed the infusion bag placed on the infusion bag feeding plate 232 to the second conveyor 720, and controls the wrapping envelope pickup unit 500 to feed the wrapping envelopes accommodated in the wrapping envelope accommodating box 400 to the lathe 730.

After the infusion bag feeding plate 232 on which the infusion bag is placed reaches the upper portion of the second conveyor 720, the control panel controls the packaging envelope conveying unit 300 to reach the lathe 730 to convey the packaging envelope of the packaging envelope conveying unit 300 to the second conveyor 720, and the packaging envelope is fitted on the infusion bag feeding plate 232 on which the infusion bag is placed.

Next, in order to separate the infusion bag transport plate 232 from the infusion bag while keeping the infusion bag housed in the packaging envelope, the control panel presses the end of the infusion bag detached from the infusion bag transport plate 232 in the direction of the second conveyor 720 by the infusion bag pressing unit 900, and then controls the infusion bag transport unit 200 to move the infusion bag transport plate 232 to the first conveyor 710.

The control panel drives the second conveyor 720 to convey the wrapping envelopes placed at the front end of the second conveyor 720 to the rear end, and stops the second conveyor 720 when the wrapping envelopes reach the vacuum sealing unit 600 provided at the rear end of the second conveyor 720.

Then, the control panel vacuums and seals the packaging envelope containing the infusion bag by the vacuum sealing unit 600.

Then, the control panel drives the second conveyor to convey the sealed packaging envelopes to the subsequent step.

Although the present invention has been described above with reference to the preferred embodiments thereof, it will be understood by those skilled in the art of the present invention that various modifications and changes can be made to the present invention without departing from the technical spirit and scope of the present invention as set forth in the appended claims.
