Description

[Technical Field]

[0001] The present invention relates to a packaging machine and a packaging method using the same that can select optimal conditions for packaging various items and improve production capacity through high-speed packaging. [Background technology]

[0002] Various packaging machines have been proposed in the past that have a bag gripping unit that grips a packaging bag and a moving body that intermittently moves the bag gripping unit for each packaging step, and that fill and seal the packaging bag with items to be packaged. Examples of such machines include a rotary packaging machine (e.g., Japanese Patent No. 6458213) that intermittently moves the bag gripping unit that grips the packaging bag for each packaging step to fill and seal the packaging bag with items to be packaged. There is also a multi-packaging machine (e.g., Japanese Patent No. 6830573) that simultaneously moves multiple bag gripping units that each grip a packaging bag intermittently for each packaging step to fill and seal the packaging bag with items to be packaged. There is also a track-type packaging machine (e.g., Japanese Patent No. 6364602) that intermittently moves the bag gripping units that grip the packaging bag arranged in a track for each packaging step to fill and seal the packaging bag with items to be packaged.

[0003] The above packaging machines provide optimal packaging for a variety of packaged items, but each has the following tendencies: Rotary packaging machines have limited production capacity because the bags are transported intermittently; Multi-unit packaging machines have large machine dimensions, which makes them difficult to transport, and the number of components tends to increase costs; Truck-type packaging machines require a large installation space, which can lead to problems with misalignment during bag transport and a short machine lifespan.

DETAILED DESCRIPTION OF THE INVENTION

[0011] In the present invention, a packaging machine P and a packaging method therefor have been realized which are space-saving and cost-effective, can select optimal conditions for packaging according to various packaging items, and can improve production capacity, by having a bag gripping section g for gripping packaging bags a, a movable body 11 which enables the bag gripping section g gripping the packaging bag a to move intermittently or continuously, and a packaging device loading table 13 which is equipped with packaging devices Q for performing each packaging process and can operate in synchronization with the movable body 11 and can reverse its operating direction. [Example]

[0012] The packaging machine of the present invention will be described with reference to an embodiment shown in FIGS. The packaging machine P of this embodiment has a bag gripping unit g for gripping packaging bags a, a movable body 11 that allows the bag gripping unit g gripping the packaging bag a to move intermittently or continuously, and a packaging device loading table 13 that is equipped with packaging devices Q (bag supply device Q1, printing device Q2, print inspection device Q3, opening device Q4, liquid filling device Q5, first sealing device Q6, second sealing device Q7, air vent device Q8, cool sealing device Q9, external discharge device Q10, etc.) for performing each packaging process, and that can operate in synchronous with the movable body 11 and can reverse its operating direction. Each component will be described in detail below.

[0013] The packaging machine P of this embodiment is an apparatus that opens the mouth of a packaging bag a, fills it with packaged items, and seals it. As shown in Figures 1 to 10, the packaging machine P includes a bag feeding process (first process) in which the packaging bags a are sequentially supplied to the bag gripping section (grip pair g in this embodiment) of the packaging section, a printing process (second process) in which expiration dates and the like are printed, a print inspection process (third process) in which print inspection is performed, a bag top opening / bag bottom opening process (fourth process) in which the mouth and bottom of the packaging bag a are opened, a filling / bottom vibration process (fifth process) in which the packaged items (e.g., liquid items) are filled into the packaging bag a and vibrations are applied to the packaged items, and a filling / bottom vibration process (fifth process) in which the packaged items (e.g., solid items) are filled. The equipment mass-produces packaging bags a filled with the contents to be packaged by repeating the following 10 steps: the second filling step (6th step) to fill packaging bag a with the contents to be packaged; the air venting step (7th step) to vent the air from inside packaging bag a; the first top sealing step (8th step) to horizontally seal the vicinity of the bag opening with a decorative seal; the second top sealing and air venting step (9th step) to horizontally top seal the vicinity of the bag opening and vent the air from inside packaging bag a; and the cooling seal and product discharge step (10th step) to cool (set) the top seal and discharge packaging bags a with the contents to be packaged from the machine.

[0014] Although this embodiment is a rotary packaging machine P, the present invention can also be applied to known linear motion type packaging machines, track type packaging machines, and the like.

[0015] 1 or 2, in this packaging machine P, a stand 14 that rotatably supports a first rotating shaft 12 extending vertically is provided on a machine base 50, and 20 pairs of bag gripping portions (grip pairs in this embodiment) g for gripping or releasing packaging bags a are provided on a moving body (disk-shaped rotating body) 11 to which the first rotating shaft 12 is attached, and these 20 pairs of bag gripping portions (grip pairs in this embodiment) g for gripping or releasing packaging bags a are provided so as to protrude radially at equal angular intervals from the first rotating shaft 12. Then, in the bag supply process (first process), the packaging machine P is configured so that the packaging bags a are picked up by a bag supply device Q1, which is one of the packaging devices Q, and the packaging bags a are supported in a vertical position hanging from the bag gripping portions (grip pairs) g that move sequentially. The packaging machine P in this embodiment is a two-machine packaging machine configured so that two bag gripping sections (grip pairs) g move sequentially at the same time so that the same packaging process is performed on two packaging bags a at the same time, but single-machine packaging machines or multiple-machine packaging machines other than two are also included in the scope of the present invention.

[0016] The movable body 11 is for enabling intermittent or continuous movement of the bag gripping portion g gripping the packaging bag a, and is configured to be capable of intermittent or continuous rotation by a first drive unit (a servo motor in this embodiment) 15, as shown in Fig. 1. Note that the movable body 11 in this embodiment is configured to be rotationally driven by the first drive unit 15, but is not limited to this, and the movable body may also be rotationally driven by an index table structure, for example.

[0017] The packaging device loading table 13 is provided with various packaging devices Q for performing each packaging process, and is configured to be operable and reversible in its direction of operation in synchronization with the moving body 11. Specifically, as shown in Fig. 1, the packaging device loading table 13 in this embodiment is attached to the upper part of a second rotating shaft 16 that is provided to extend vertically within the first rotating shaft 12, and the rotational drive of the second driving unit 18 (a servo motor in this embodiment) is transmitted to the packaging device loading table 13 via a first gear 17 provided at the lower part of the second rotating shaft 16, a second gear 19 fixed to the shaft of the second driving unit 18, and a transmission belt 20, so that the packaging device loading table 13 can rotate forward and backward.

[0018] In this embodiment, the movable body (disk-shaped rotating body) 11 and the packaging device loading table 13 are arranged coaxially, with the movable body 11 being rotatable in the forward direction and the packaging device loading table 13 being rotatable in the reverse direction. This configuration allows the packaging machine to be made more compact, thereby further saving space and reducing costs. It also solves the problems of misalignment during bag transport and a shortened machine life due to a complicated structure.

[0019] Furthermore, since the packaging device loading table 13 in this embodiment is provided above the moving body 13, each packaging device Q can be disposed near the center of the packaging machine, on the packaging device loading table 13, improving accessibility from outside the machine and improving maintainability. Also, when the packaging device loading table 13 rotates (moves) by a certain distance, the packaging devices Q also rotate (move) by a certain distance.

[0020] The packaging device Q broadly includes devices used in the packaging process, including, but not limited to, bag feeders, printers, print inspection devices, bag top opening devices, bag bottom opening devices, liquid filling devices, solid filling devices, bottom vibration devices, steam filling devices, air venting devices, sealing devices, cool sealing devices, and external discharge devices. Also, in Figure 1, the bag feeders Q1 and liquid filling devices Q5 are depicted as being on both sides of the packaging device loading table 13, but, like the opening device Q4 and first sealing device Q6, they are attached to the packaging device loading table 13.

[0021] The packaging machine P of this embodiment is configured such that the bag gripping unit g gripping the packaging bag a is continuously moved by the movable body 11, and the packaging device loading table 13 is operated in synchronization with the movable body 11. After each packaging step is performed by the packaging devices Q (bag feeder Q1, printer Q2, print inspection device Q3, opening device Q4, liquid filling device Q5, first sealing device Q6, second sealing device Q7, air vent device Q8, cool-sealing device Q9, external discharge device Q10, etc.) near the location where each packaging step is performed, the packaging device loading table 13 reverses its operating direction and returns, repeating this operation. This allows each packaging step to be performed while the bag gripping unit g gripping the packaging bag a is continuously moved, thereby improving production capacity through high-speed packaging. Note that this packaging method is the first type of packaging method that can be selected for the packaging machine P of this embodiment.

[0022] 17, the operation of the movable body 11 is controlled to rotate continuously, and the operation of the packaging device loading table 13 is controlled to alternate between rotating in the same direction (forward direction) as the movable body 11 in synchronization with the operation of the movable body 11 and rotating in the opposite direction (returning in the opposite direction). By repeating such operations of the movable body 11 and the packaging device loading table 13, for example, near the eighth step (first top sealing step of horizontally decoratively sealing the vicinity of the bag opening), heat sealing can be performed while the packaging device loading table 13 is rotating in the same direction (forward direction) as the movable body 11 in synchronization with the operation of the movable body 11, and the packaging process can be performed continuously without intermittent operation of the movable body 11 which moves the bag gripping unit g gripping the packaging bag a, and production capacity can be improved through high-speed packaging. More specifically, if the moving body 11 is moved continuously, the moving speed of the packaging bag a can be slowed down at the same production capacity as when the moving body 11 is moved intermittently, and the shaking of the packaging bag a and the falling out of the packaged items can be suppressed, thereby enabling the speed to be increased and improving the production capacity.

[0023] More specifically, in the vicinity of the eighth step (first top sealing step of horizontally decoratively sealing the vicinity of the bag opening), heat sealing is carried out sequentially as shown in FIGS. That is, in the state shown in Figure 11, the packaging device loading table 13 is in a stopped state between rotating in the same direction (forward direction) as the moving body 11 in synchronization with the movement and rotating in the reverse direction (returning in the reverse direction), and the paired seal bar 21 is in an open state. Next, the states shown in Figures 12 and 13 show a state in which the packaging device loading table 13 rotates counterclockwise in the same direction (forward direction) as the moving body 11 in synchronization with the movement and follows the moving body 11, during which the seal bar 21 closes and simultaneously heat-seals the packaging bag a3 and the packaging bag a4. Furthermore, the state shown in Figure 14 shows a state in which the packaging device loading table 13 has stopped following the moving body 11 and has stopped, and the seal bar 21 is open. Thereafter, as shown in Figure 15, the packaging device loading table 13 rotates in the reverse direction (returning in the reverse direction). As shown in Figure 16, the packaging machine P of this embodiment performs the operations shown in Figures 11 to 15 to heat seal the packaging bags a5 and a6 that are next transported by the moving body 11, and by repeating these operations, heat sealing is performed sequentially even when the moving body 11 is continuously rotating.

[0024] In addition, the packaging machine P of this embodiment is configured so that the bag gripping unit g gripping the packaging bag a is intermittently moved by the movable body 11, and the packaging device loading table 13 is operated in synchronization with the movable body 11. After the packaging process is performed by the packaging devices Q (bag feeder Q1, printer Q2, print inspection device Q3, opening device Q4, liquid filling device Q5, first sealing device Q6, second sealing device Q7, air vent device Q8, cool-sealing device Q9, external discharge device Q10, etc.), the direction of operation of the packaging device loading table 13 is reversed and the returning operation is repeated. This allows each packaging process to be performed even while the bag gripping unit g gripping the packaging bag a is moving, thereby improving production capacity through high-speed packaging. Note that this packaging method (a packaging method in which each packaging process can be performed even during movement when the intermittent movement setting is used) is the second packaging method that can be selected for the packaging machine P of this embodiment.

[0025] Furthermore, the packaging machine P of this embodiment can control the moving body 11 to intermittently move the bag gripping unit g gripping the packaging bag a, and can stop the packaging device loading table 13 to perform the packaging process with each packaging device Q (bag feeder Q1, printer Q2, print inspection device Q3, opening device Q4, liquid filling device Q5, first sealing device Q6, second sealing device Q7, air vent device Q8, cool-sealing device Q9, and discharge device Q10, etc.). This allows for normal packaging, in which each packaging process is performed by intermittently moving the bag gripping unit g gripping the packaging bag a. This packaging method is the third type of packaging method that can be selected by the packaging machine P of this embodiment. The packaging machine P of the present invention can select the optimal packaging method and conditions (such as movement speed) from these three types of packaging methods depending on the type of packaged material (e.g., liquid, solid, dry, powder, granular material), etc.

[0026] As described above, the packaging machine P of the present invention can save space and reduce costs, can select optimal conditions for packaging various packaged items (liquids, solids, dry goods, powders, granules, etc.), and can improve production capacity. Furthermore, each packaging device Q (bag feeding device Q1, printing device Q2, print inspection device Q3, opening device Q4, liquid filling device Q5, first sealing device Q6, second sealing device Q7, air venting device Q8, cooling sealing device Q9, external discharge device Q10, etc.) is installed near the center of the packaging machine P on the packaging device loading table 13, which provides excellent visibility and maintainability, including the packaging bag a, and improves durability.

[0027] Next, the packaging method of the packaging machine of the present invention will be explained. However, the packaging machine P is as described above, so its explanation will be omitted. The packaging method of this embodiment is a packaging method using a packaging machine P having a bag gripping unit g for gripping packaging bags a, a movable body 11 that can move the bag gripping unit g gripping the packaging bag a intermittently or continuously, and a packaging device Q (bag feeding device Q1, printing device Q2, print inspection device Q3, opening device Q4, liquid filling device Q5, first sealing device Q6, second sealing device Q7, air vent device Q8, cooling sealing device Q9, discharge device Q10, etc.) for performing each packaging process, and a packaging device loading table 13 that can operate in synchronization with the movable body 11 and can reverse its operating direction, characterized in that the bag gripping unit g gripping the packaging bag a is continuously moved by the movable body 11, and the packaging device loading table 13 is operated in synchronization with the movable body 11 so that the packaging process is performed by the packaging device Q, and then the operating direction of the packaging device loading table 13 is reversed and the returning operation is repeated. This allows each packaging step to be carried out while continuously moving the bag gripping section g gripping the packaging bag a, thereby improving production capacity through high-speed packaging.

[0028] Specifically, in the bag supply process (first process) in which packaging bags a are sequentially supplied to the bag gripping section (grip pair g in this embodiment) of the packaging section, the bag supply process is performed by bag supply device Q1. Bag supply device Q1 has a first bag capture section 23 for capturing packaging bags a arranged on bag supply conveyor 22 one by one, and a second bag capture section 24 for receiving packaging bags a held by first bag capture section 23 and then transferring them to bag gripping section (grip pair) g, and is attached to packaging device loading table 13 as shown in FIG.

[0029] The first bag capture section 23 has a rotating arm (multiple bag capture pipes) 25 that captures each packaging bag a that is transported sequentially to the downstream end by the bag supply conveyor 22, rotates it, and holds it in a vertical position, and the rotating arms 25 each have a suction cup 26 at their lower end that adsorbs the packaging bag a from the top side.

[0030] As shown in Figure 3, the bag supply device Q1 uses the first bag catcher 23 to pick up packaging bags a arranged on the bag supply conveyor 22 one by one using suction cups 26, and holds the packaging bags a in a vertical position. The second bag catcher 24 then goes to pick up the waiting packaging bags a, and once the pick-up is complete, the packaging device loading table 13 rotates synchronously with the continuously rotating movable body 11 for a certain period, and during this synchronous rotation, the packaging bag a is handed over from the second bag catcher 24 to the bag gripper (grip pair) g. The packaging device loading table 13 then rotates in the reverse direction (returning in the opposite direction). By repeating these operations, bags are sequentially supplied while the movable body 11 is continuously rotating near the first process (bag supply process).

[0031] In the printing process (second process) for printing expiration dates and the like, as shown in Fig. 4, while the packaging bag a supported in a suspended state by the bag gripping portion (grip pair) g is continuously moving, when a predetermined signal is detected, printing is performed by the printing device Q2 attached to the packaging device loading table 13 while rotating synchronously with the moving body 11. After that, the packaging device loading table 13 rotates in the reverse direction (returning in the opposite direction), and by repeating these operations, printing is performed sequentially while the moving body 11 is continuously rotating near where the second process (bag supply process) is performed.

[0032] In the print inspection process (third process) where print inspection is performed, as shown in Figure 5, while packaging bags a supported in a suspended state by bag gripping portions (grip pairs) g are continuously moving, when a predetermined signal is detected, print inspection is performed by print inspection device Q3 attached to packaging device loading table 13 while rotating synchronously with moving body 11. After that, packaging device loading table 13 rotates in the reverse direction (returning in the opposite direction), and by repeating these operations, print inspection is performed sequentially while moving body 11 is continuously rotating near where the third process (bag supply process) is performed.

[0033] In the bag top opening / bag bottom opening step (fourth step) for opening the bag top and bag bottom of the packaging bag a, as shown in Fig. 6, while the packaging bag a supported in a suspended state by the bag gripping portion (grip pair) g moves continuously, the top opening and the bottom opening of the bag are performed by the opening device Q4 attached to the packaging device loading table 13 while rotating synchronously with the moving body 11. Thereafter, the packaging device loading table 13 rotates in the reverse direction (returning in the opposite direction), and by repeating these operations, the bag top opening and the bag bottom opening are performed sequentially while the moving body 11 is continuously rotating near the fourth step (bag top opening / bag bottom opening step).

[0034] In the filling and bottom vibration process (fifth process) in which the packaging bag a is filled with the packaged item (liquid item) and the packaged item is vibrated, as shown in Figure 1 or 7, while the packaging bag a supported in a suspended state by the bag gripping section (grip pair) g moves continuously, the liquid filling device Q5 and bottom vibration device (not shown) attached to the packaging device loading table 13 rotate synchronously with the moving body 11 to fill the packaging bag a with the packaged item (liquid item) and to vibrate the packaged item. After that, the packaging device loading table 13 rotates in the reverse direction (returning in the opposite direction), and by repeating these operations, filling and bottom vibration are performed sequentially while the moving body 11 is continuously rotating near the location where the fifth process (filling and bottom vibration process) is performed.

[0035] In the second filling step (sixth step) of filling the packaging bag a with the packaged item (solid item), while the packaging bag a supported in a suspended state by the bag gripping portion (grip pair) g continues to move, the packaged item (solid item) is filled into the packaging bag a by a solid item filling device (not shown) attached to the packaging device loading table 13 during synchronous rotation with the moving body 11. Thereafter, the packaging device loading table 13 rotates in the reverse direction (returns to rotate in the opposite direction), and by repeating these operations, the second filling is sequentially performed while the moving body 11 continues to rotate near the sixth step (second filling step).

[0036] In the air removal step (seventh step) of removing air from the packaging bag a, while the packaging bag a supported in a suspended state by the bag gripping portion (grip pair) g continues to move, air is removed from the packaging bag a by an air removal device (not shown) attached to the packaging device loading table 13 while rotating synchronously with the moving body 11. Thereafter, the packaging device loading table 13 rotates in the reverse direction (returning in the opposite direction), and by repeating these operations, air is sequentially removed from the packaging bag a while the moving body 11 continues to rotate near the seventh step (air removal step).

[0037] In the first top sealing step (eighth step) of horizontally decoratively sealing the vicinity of the bag opening, as shown in Fig. 8, while the packaging bag a supported in a suspended state by the bag gripping portion (grip pair) g continues to move, a first sealing device Q6 attached to the packaging device loading table 13 rotates synchronously with the moving body 11 to horizontally decoratively seal the vicinity of the bag opening. The packaging device loading table 13 then rotates in the reverse direction (returns to rotate in the opposite direction), and by repeating these operations, top sealing is sequentially performed in the vicinity of where the eighth step (first top sealing step) is performed while the moving body 11 continues to rotate.

[0038] In the second top sealing and air purging process (ninth process) in which the bag opening is horizontally top-sealed and air is purged from inside the packaging bag a, as shown in Figure 9, while the packaging bag a supported by the bag gripping section (grip pair) g in a suspended state moves continuously, the second sealing device Q7 attached to the packaging device loading table 13 seals the bag opening horizontally while rotating synchronously with the moving body 11, and air is purged from inside the packaging bag a by the air purging device Q8. The packaging device loading table 13 then rotates in the reverse direction (returning in the opposite direction), and these operations are repeated, so that the top is sealed and air is purged from inside the packaging bag a in sequence while the moving body 11 continues to rotate near the ninth process (second top sealing and air purging process).

[0039] In the cooling sealing and product discharge process (10th process), in which the top seal is cooled (sealed) and the packaging bag a containing the packaged item is discharged outside the machine, as shown in Figure 10, the packaging bag a, supported in a suspended state by the bag gripping section (grip pair) g, moves continuously, and is then cooled and sealed by the cooling sealing device Q9 and the discharge device Q10 attached to the packaging device loading table 13 while rotating synchronously with the moving body 11, and then discharged outside the machine as a product. The packaging device loading table 13 then rotates in the reverse direction (returns to rotate in the opposite direction), and these operations are repeated, so that the cooling sealing and product discharge are sequentially performed near the 10th process (cooling sealing and product discharge process) while the moving body 11 is continuously rotating.

[0040] Furthermore, in the packaging method using the packaging machine P of this embodiment, the bag gripping unit g gripping the packaging bag a is moved intermittently by the moving body 11, and the packaging device loading table 13 is operated in synchronization with the moving body 11, so that after the packaging process is performed by the packaging device Q, the direction of movement of the packaging device loading table 13 is reversed and the returning operation can be repeated. This allows each packaging process to be performed even while the bag gripping unit gripping the packaging bag is moving, and production capacity can be improved through high-speed packaging.
