It will be understood by those within the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

Aiming at the defects that in the 3C industry, the product packaging process is multiple, complicated, small in space and dependent on manual operation, the embodiment of the invention provides multifunctional integrated small-sized full-automatic packaging equipment.

Within the scope of the present invention, 3C products include, but are not limited to, computers, tablets, cell phones, smartwatches, or digital audio players. The invention is particularly suitable for packaging mobile phones and smart watches.

As shown in fig. 1 and 2, the packaging apparatus 10 provided by the embodiment of the present invention includes a box opening device 100, a product supplying device 200, and a product aligning device 300. The products to be packaged here may refer to products contained in a color box, e.g. a carton, or may be the products themselves (i.e. without a package). Embodiments of the present invention provide a packaging apparatus 10 that is particularly suitable for packaging color boxes, such as cartons, that contain 3C products therein.

The case opening device 100 includes a magazine mechanism 110 configured to store the folded case 20 and a case opening mechanism 120 configured to open the folded case 20 and place the opened case 20 in a case loading position.

The product supply device 200 is configured to supply the product 30.

The product alignment apparatus 300 is disposed above the case opening apparatus 100 and includes an alignment table 310, a first conveyance mechanism 320, and a second conveyance mechanism 330. The first conveying mechanism 320 is configured to convey the products 30 supplied by the product supply device 300 to the aligning table 310 to arrange a plurality of products, for example, 20 products 30, into a product group on the aligning table 310, and the second conveying mechanism 330 is configured to integrally convey the product group on the aligning table 310 into the case 20 at the boxing position.

By arranging the product arraying device 300 above the box opening device 100, the space above the box opening device can be fully utilized, extra space does not need to be occupied, the miniaturized packaging equipment integrating the box opening function, the arraying function and the box filling function is realized, and the automation degree of product packaging is improved.

The packaging equipment can meet the requirements of box alignment, boxing and the like with the specification of (length L is 50-150mm) × (width W is 30-100mm) × (height H is 40-160mm), and cartons with the specification of (length L is 200-.

In some embodiments, the packaging device of the present invention has a length of no more than 1.7m, a width of no more than 1.9m, and a height of no more than 2.5 m.

Some embodiments of the unpacking device 100 of the invention are described below in conjunction with fig. 3-7.

As shown in fig. 3 and 4, the folded boxes 20 are stored vertically in the tote mechanism 110. The tank mechanism 110 may include a support portion 111, a stopper plate 112, a push plate 113, and a spring puller (not shown). The support 111 is configured to support the folded box 20. The restraining plate 112 is configured to restrain the folded box 20 from both sides. The spring tensioner is configured to apply a pulling force to the push plate 113 so that the push plate 113 presses the case 20 stored in the tank mechanism 110. Thus, whenever one case 20 is taken by the case opening mechanism 120, the remaining cases 20 in the magazine mechanism 110 are pushed forward by the push plate 113, i.e., toward the case opening mechanism 120, so that the case opening mechanism 120 can take the case at the same position.

Further, the support 111 may be two opposing power belts configured to move the folded box 20 forward to cooperate with the push plate 113 to feed the box 20 in the tank mechanism 110 toward the box opening mechanism 120.

Further, the tote mechanism 110 may also include at least one bar 114, the bar 114 being used to block the folded case 20 from falling without affecting the opening of the case by the case opening mechanism 120 and without damaging the case. In the embodiment shown in FIG. 3, the tote mechanism 110 includes two bars 114 that serve to block the top edge of the folded case 20 on both sides.

In some embodiments, the unpacking mechanism 120 may include a suction cup set, particularly a vacuum suction cup set 121, an arc-shaped guide rod 122, and a drive assembly 123. The suction cup set 121 is configured to hold the folded box 20, and the driving assembly 123 is configured to drive the suction cup set 121 to move relative to the magazine mechanism 110. When opening the box, the driving assembly 123 first drives the suction cup set 121 to move toward the magazine mechanism 110 so as to suck a folded box 20 from the magazine mechanism 110; the drive assembly 123 then drives the suction cup set 121 with its gripped box back away from the magazine mechanism 110; during the return of the group of suction cups 121, the box held by the group of suction cups 121 is opened due to the guiding and squeezing action of the arc-shaped guide rods 122.

Further, a guide plate 124 for positioning the opened case may be fixed to one end of the arc guide bar 122.

In some embodiments, the driving assembly 123 may be a driving cylinder, and the suction cup group 121 is fixedly connected to a movable end of the driving cylinder directly or indirectly. In other embodiments, the driving assembly 123 may also include a motor and a belt transmission structure, or a motor and a rack and pinion, etc., which is not particularly limited in the present invention.

In some embodiments, the case opening device 100 may include a flap mechanism 140 for folding the bottom flap of the case. The flap mechanism 140 includes flap panels, not shown, for folding the front and rear bottom flaps of the box, which may be constructed, for example, to be reversible. As shown in fig. 3 and 4, the folding mechanism 140 may further include a first folding lever 141 for folding the left bottom cover of the luggage and a second folding lever 142 for folding the right bottom cover of the luggage, the first folding lever 141 and the second folding lever 142 being configured to be rotatable. After the box is opened by the box opening mechanism 120, the cover folding plate is turned over so as to fold the front bottom cover and the rear bottom cover of the box; then, the first and second flap bars 141 and 142 are driven to rotate, for example, by the air cylinder 143, so as to fold the left and right bottom covers of the box, and then the flap may be returned to the original position, and the opened box 20 is supported by the first and second flap bars 141 and 142.

As shown in fig. 3 and 4, the box opening device 100 further includes a cover guiding mechanism 130 disposed above the box opening mechanism 120, and the cover guiding mechanism includes a cover guiding plate 131, a cover guiding lifting assembly 132, and a cover guiding moving assembly 133. The cap guide lifting assembly 132 is configured to drive the cap guide plate 131 to move in a vertical direction so that the cap guide plate 131 can be inserted into the case 20 at the boxing position. The flap moving assembly 133 is configured to drive the flap 131 to move in a horizontal direction so that the flap 131 can push the lid 21 of the box 20 in the boxing position outward to avoid the free lid 21 from interfering with the placement of the material into the opened box 20.

Typically, the lid guide mechanism is activated after the bottom folding of the box is completed. When the cover guiding mechanism works, the cover guiding lifting assembly firstly enables the cover guiding plate to descend so that the cover guiding plate extends into the box, and then the cover guiding moving assembly enables the cover guiding plate to move outwards along the horizontal direction so as to push the top cover of the box away. The bottom foam, side board, product group, etc. may then be placed into the box.

In some embodiments, the cap lifting assembly 132 is configured to be driven by an air cylinder. For example, as shown in fig. 5, the cap lifting assembly 132 includes a support plate 1321 and a lifting cylinder 1322, the support plate 1321 is provided with a vertical rail 1322, the cap plate 131 is movably mounted on the support plate 1321 along the vertical rail 1322, and the lifting cylinder 1322 is used for driving the cap plate 131 to move along the vertical rail 1322.

Of course, in other embodiments, the cap lifting assembly 132 may also be configured to be driven by a motor, such as a stepper motor and a rack and pinion or a timing belt.

Alternatively or additionally, the cap moving assembly 133 may also be configured to be driven by an air cylinder. In this case, the cover plate 131 is directly fixed to the movable end of the cylinder, for example.

In some embodiments, the cover guiding mechanism 130 includes at least two cover guiding plates 131. Each of the guide cover plates 131 is provided with a guide cover moving assembly 133. Each flap-moving assembly 133 is configured to drive the associated flap 131 in a horizontal direction so that the associated flap 131 can push at least one lid 21 of the open box 20 away. Preferably, each flap 131 is assigned a different flap moving assembly 133, i.e., each flap 131 has its own separate flap moving assembly 133. For example, each of the guide cover plates 131 is provided with a respective driving cylinder 133, and the movable end 1331 of each driving cylinder 133 is fixedly connected with the corresponding guide cover plate 131.

Of course, in other embodiments, one cover guiding moving assembly 133 may be used to move at least two cover guiding plates 131 in the horizontal direction at the same time.

In the embodiment shown in fig. 5, the cover guiding mechanism 130 includes two cover guiding plates 131, i.e., a first cover guiding plate 131a and a second cover guiding plate 131 b.

Some embodiments of the product lifting mechanism 240 of the present invention are described below in conjunction with fig. 13-17.

As shown in fig. 13 and 14, the product lifting mechanism 240 includes a support plate 241, a first grasping assembly 242, a second grasping assembly 243, and a moving mechanism 244. A first gripper assembly 242 and a second gripper assembly 243 are movably supported on the support plate 241 and are configured for gripping and releasing products. The moving mechanism 244 is configured to reciprocate the first gripper assembly 242 and the second gripper assembly 243 offset from each other between a common pick location for gripping the products and a common discharge location for releasing the products.

That is, under the action of the moving mechanism 244, the first and second grasping

assemblies

242 and 243 are moved to a common picking position, offset from each other, to grasp a product, and lift the grasped product to a common placing position, offset from each other, to release the product.

In some embodiments, the first gripper assembly 242 and the second gripper assembly 243 each comprise a suction cup set for sucking the product, such as a vacuum suction cup set or an electromagnetic suction cup set. Preferably, the first gripping assembly 242 and the second gripping assembly 243 each comprise a set of vacuum suction cups, so as to enable the suction of the product to be achieved simply and at low cost.

In some embodiments, the suction cup sets of the first and

second gripper assemblies

242, 243 are arranged with their suction cups facing the side so as to grip the product from the side of the product. In other embodiments, the sets of suction cups of the first and

second gripper assemblies

242, 243 are arranged with their suction cups facing downwards so as to hold the product from its top surface.

Preferably, the common removal position and the common discharge position are arranged on the same axis S, in particular on the same vertical axis. Thereby enabling a more compact product lifting mechanism.

In some embodiments, the moving mechanism 244 is configured to move the first gripper assembly 242 and the second gripper assembly 243 simultaneously in opposite directions from each other, thereby effecting offset vertical movement of the first gripper assembly 242 and the second gripper assembly 243 from each other. That is, the moving mechanism 244 is designed such that, when the first grasping assembly 242 is moved in the vertical direction from the common discharge position P2 to the common take-out position P1, the second grasping assembly 243 is simultaneously moved in the direction opposite to the direction from the common take-out position P1 to the common discharge position P2, as shown in fig. 15; while the first grasping assembly 242 moves in the vertical direction from the common take-up position P1 to the common discharge position P2, the second grasping assembly 243 simultaneously moves in the vertical direction from the common discharge position P2 to the common take-up position P1, as shown in fig. 16.

In some embodiments, the movement mechanism 244 includes a first guide 2441, a second guide 2442, a first slider 2443, a second slider 2444, and a drive assembly 2445. The first guide portion 2441 and the second guide portion 2442 are provided on the support plate 241 and vertically extend in parallel to each other. The first slider 2443 is supported on the support plate 241 so as to be movable along the first guide portion, and the second slider 2444 is supported on the support plate 241 so as to be movable along the second guide portion. The first gripper assembly 242 is supported on a first slide 2443 and the second gripper assembly 243 is supported on a second slide 2444.

second sliders

2443, 2444 are driven simultaneously by the single drive assembly 2445 to move back and forth in the vertical direction along the first and

second guides

2441, 2442, in particular the first and

second sliders

2443, 2444 are driven simultaneously in opposite directions to each other. This makes it possible to lift the product alternately by the first gripper assembly 242 and the second gripper assembly 243 in a simple, cost-effective and efficient manner.

Of course, in other embodiments, the moving mechanism 244 may include first and second driving assemblies respectively configured to the first and

second sliders

2443 and 2444, thereby enabling more flexible driving control.

In some embodiments, the driving assembly 2445 includes a motor 2445a, in particular a stepping motor, and a synchronous belt drive 2445b configured to drive the synchronous belt drive to move, and the first slider 2443 and the second slider 2444 are respectively fixed on two opposite belt portions a1, a2 of a synchronous belt of the synchronous belt drive, so that the synchronous belt can simultaneously drive the first grasping assembly 242 and the second grasping assembly 243 to move in opposite directions to each other through the first slider 2443 and the second slider 2444 under the driving of the motor. For example, when the motor drives the timing belt to rotate clockwise, the first slider 2443 drives the first grasping assembly 242 to move upward in the vertical direction to move from the common discharge position P1 to the common discharge position P2, and the second slider 2444 drives the second grasping assembly 243 to move downward in the vertical direction to move from the common discharge position P2 to the common discharge position P1. When the motor drives the timing belt to rotate counterclockwise, the first slider 2443 drives the first grasping assembly 242 to move downward in the vertical direction so as to move from the common discharge position P2 to the common take-out position P1, and the second slider 2444 drives the second grasping assembly 243 to move upward in the vertical direction so as to move from the common take-out position P1 to the common discharge position P2.

For example, the first guide portion 2441 and the second guide portion 2442 are disposed in front of the support plate 241, and the driving assembly 2445 is disposed behind the support plate 241. An opening 2445c is provided between the first guide portion 2441 and the second guide portion 2442 in the support plate, through which the first slider 2443 and the second slider 2444 can be fixed to the timing belt.

Wherein the first guide groove 2448 and the second guide groove 2449 are shaped such that the first grasping assembly 242 and the second grasping assembly 243 are moved back to each other when meeting in opposite directions from each other upon actuation of the actuation assembly, as shown in fig. 17. The common removal position and the common discharge position are preferably arranged on the same vertical axis S.

Here, when the first pulley 2450 is moved in the vertical direction by the first slider 2443, the first pulley 2450 slides in the first guide groove 2448, thereby moving the first grasping assembly 242 fixed to the first pulley in the horizontal direction along the third guide portion 2446. Similarly, when the second pulley 2451 is moved in the vertical direction by the second slider 2444, the second pulley 2451 slides in the second guide groove 2449, so that the second grasping assembly 243 fixed to the second pulley is moved in the horizontal direction along the fourth guide portion 2447.

In some embodiments, the first guide groove 2448 and the second guide groove 2449 are shaped such that, at least in some regions, the first guide groove 2448 and the second guide groove 2449 are at different horizontal distances from each other at different vertical heights, and the first guide groove 2448 and the second guide groove 2449 are at a maximum distance from each other at a meeting height P3 of the first and second grasping

assemblies

242 and 243.

The paper ring gripping mechanism 520 includes a sixth suction cup group (especially, a vacuum suction cup group) 521, a third support plate 522, and a fourth driving part 523. The sixth suction cup group is fixed to the third support plate 522, and the fourth driving part 523 is configured to drive the third support plate 522 together with the sixth suction cup group fixed thereto to rotate, for example, about 90 °, between the paper ring gripping position and the paper ring spreading position. The sixth suction cup set sucks an unexpanded paper ring from the paper ring storage mechanism in the paper ring gripping position and aligns with the fifth suction cup set 531 in the paper ring expanded position to cooperate to expand the paper ring. Here, the sixth suction cup group 521 is located directly above the paper ring storage mechanism 510 in the paper ring gripping position to suck an unexpanded paper ring, and the sixth suction cup group 521 is located directly above the fifth suction cup group 531 in the paper ring expanding position to expand the paper ring in cooperation with the fifth suction cup group 531.

Here, the fourth driving part 523 may be a rotation driving cylinder or a motor, and the present invention is not particularly limited thereto.

In some embodiments, the paper ring gripping mechanism 520 may further include a fifth driving part 524, and the fifth driving part 524 is configured to drive the third support plate 522 together with the sixth suction cup group 521 fixed thereon to move vertically, i.e., to move in the vertical direction Z.

In an exemplary operation of the collar device 500, the initial position of the sixth suction cup group 521 is a paper ring grabbing position, and the fifth driving part 524 first drives the sixth suction cup group 521 to move vertically downward to suck an unexpanded paper ring from above, and then drives the sixth suction cup group 521 to move vertically upward. The fourth driving part 523 then drives the sixth suction cup group 521 to rotate to the paper ring unfolding position. Then, the fifth suction cup group and the sixth suction cup group are vertically moved relatively, so that the fifth suction cup group sucks the unexpanded paper ring from below. And finally, pulling the unexpanded paper ring open through the vertical relative movement of the fifth sucker group and the sixth sucker group.

In some embodiments, the paper loop forming mechanism 540 includes an upper forming plate 541 and a lower forming plate 542 disposed opposite each other and includes a sixth drive portion 543 and a seventh drive portion 544. The sixth driving portion 543 is configured to drive the upper forming plate 541 and the lower forming plate 542 to move relative to each other, in particular, to move relative to each other in the vertical direction Z, and the seventh driving portion 544 is configured to drive the upper forming plate 541 and the lower forming plate 542 to move relative to the paper ring unwinding mechanism 530, for example, to move in the horizontal direction Y. Here, the sixth driving part 543 and the seventh driving part 544 may be linear driving cylinders or include a motor and a rack and pinion, which is not particularly limited in the present invention.

During one exemplary operation of the paper ring forming mechanism 540, after the fifth suction cup group and the sixth suction cup group cooperate with each other to pull open the unexpanded paper ring, the fifth suction cup group and the sixth suction cup group keep sucking the pulled paper ring. Next, the seventh driving part 444 drives the upper forming plate 541 and the lower forming plate 542 to move toward the fifth suction cup group 531 in the horizontal direction Y, so that the upper forming plate 541 and the lower forming plate 542 extend into the pulled paper ring 60 by a distance, at which time the fifth suction cup group and the sixth suction cup group release the paper ring. The sixth driving portion 543 then drives the upper forming plate 541 and the lower forming plate 542 to move away from each other in the vertical direction Z so as to spread the pulled paper ring 60 into a predetermined shape, for example, a rectangle. Then, the seventh driving portion 444 drives the upper forming plate 541 and the lower forming plate 542 together with the spread paper ring 60 held thereon to move back in the horizontal direction Y to wait for a collar.

As shown in fig. 35 and 36, collar arrangement 500 further includes a collar seat 550 and an eighth drive 560 for receiving product 30.

The collar seat 550 is capable of receiving the product 30 in a product receiving position and of receiving the paper ring 60 formed by the paper ring forming mechanism 540 in a collar position.

In a specific example, the eighth driving part 560 includes a slider 561, a slide rail 562, and a driving cylinder 563, the collar seat 550 is fixed on the slider 561, the slider 561 is directly or indirectly connected with the driving cylinder 563, and the slider 561 can slide on the slide rail 562 by the driving of the driving cylinder 563. Of course, the present invention is not limited thereto, and the eighth driving part 560 may also include a motor and a rack and pinion or a motor and a driving belt, for example.

In one exemplary operation of collar arrangement 500, a paper ring gripping mechanism, not shown, such as a vacuum chuck, is utilized to place a product into collar seat 550, which is in a product receiving position, as shown in FIG. 3. The eighth driving part 560 then drives the collar seat 550 with the product 30 therein to move in the horizontal direction X to the collar position (here directly in front of the paper ring forming mechanism 540), and then the seventh driving part 544 drives the upper and lower forming

plates

541, 542 with the spread paper ring 60 held thereon to move in the horizontal direction Y toward the collar seat 550 at the collar position, thereby nesting the spread paper ring 60 onto the product 30 at the collar seat 550, as shown in fig. 36.

Further, the ninth driving part 553 is also configured to drive the pressing arm 552 to rotate so that the pressing arm can rotate above the product 30 in the collar seat. For example, the ninth driving part 553 first drives the pressing arm 552 to move upward in the vertical direction Z, then drives the pressing arm 552 to rotate to just above the product 30 in the collar seat, and then drives the pressing arm 552 to move downward in the vertical direction Z so as to press the product 30 downward from a position above the product.

Here, the ninth driving part 553 may preferably include a cylinder driving structure.

Preferably, the collar seat 550 comprises at least two pressing arms 553 arranged on the same side of said first base plate 551, each provided with a separate ninth driving portion 553. This ensures that the product 30 is reliably pressed into the collar seat 550.

Further, as shown in fig. 35 and 36, the collar base 550 further includes a first side plate 554 and a second side plate 555 fixed opposite to each other on both sides of the first bottom plate 551, and a receiving space for receiving a product is formed between the first side plate 554 and the second side plate 555. The receiving space is here larger than the volume of the product, so that the product, when placed in the receiving space, does not lie against the first side panel 554 and the second side panel 555, but at a distance from each other. At least one first pressure piece 556, in particular at least two first pressure pieces, is mounted on the first side plate 554 so as to be movable relative to the second side plate 555, and at least one second pressure piece 557, in particular at least two second pressure pieces, is mounted on the second side plate 555 so as to be movable relative to the first side plate 554. Thus, after the paper ring forming mechanism 540 sleeves the paper ring 60 to be spread and formed on the product 30, the first pressing block 556 and the second pressing block 557 can move relative to each other to press the paper ring to the product 30 from both sides of the product 30, respectively, so that the paper ring forming mechanism 540 is disengaged from the paper ring 60 to be spread and formed by the paper ring forming mechanism 540.

In the embodiment shown in fig. 35 and 36, two first press blocks 556 are mounted on the first side plate 554, and two second press blocks 557 are mounted on the second side plate 555. The first pressure piece 556 and the second pressure piece 557 may be driven by, for example, air cylinders.

In some embodiments, the first base panel 551 is configured to support a portion of the product 30 so that the paper ring-forming mechanism 540 can nest the expanded paper ring 60 onto the product 30 from the unsupported bottom of the product 30. Correspondingly, the collar arrangement 500 further comprises a second bottom plate 570 fixed in the moving direction X of the collar seat 550, which second bottom plate 570 is arranged to support the product 30 in cooperation with the first bottom plate 551 of the collar seat in the product receiving position.

Preferably, the second bottom plate 570 is configured to be vertically movable, for example, fixedly coupled to the movable end of the driving cylinder 171.

In one exemplary operation of collar assembly 500, collar seat 550 is first placed in a product receiving position, with first base panel 551 and second base panel 570 together supporting received product 30; after the product 30 is put in, the pressing arm 553 moves to press the product 30 downward from a position above the product; then, the second bottom plate 570 moves vertically downward, and then the eighth driving part 560 drives the collar seat 550 to move from the product receiving position to the collar position along the horizontal direction X, so that the paper ring forming mechanism 540 sleeves the spread-formed paper ring 60 on the product; the first and second press blocks 556, 557 are then moved relative to each other to press the paper ring 60 against the product 30 from either side of the product 30, respectively, so that the paper ring forming mechanism 540 can be disengaged from the paper ring 60; finally, the eighth drive 560 drives the collar seat 550 back in the horizontal direction X from the collar position to the product receiving position, and the second bottom plate 570 moves vertically upward back to the original position.

Further, as shown in fig. 37 and 38, a plurality of second bottom plates 570 may be provided, and the eighth driving part 560 is further configured to drive the collar seat 550 to move between the different second bottom plates 570.

In some embodiments, a horizontally extending baffle is disposed on top of at least one of the stop side plates 6112.

In some embodiments, as shown in fig. 2 and 18, the packaging apparatus 10 further comprises a bagging device 700 disposed above the unpacking device 100, the bagging device 700 being configured to open and expand a bag, such as a plastic bag, so that the second conveying mechanism 330 can place the product groups on the alignment table 310 into the bag opened by the bagging device 700, thereby enabling automated bagging and bagging operations.

The bagging apparatus 700 is particularly positioned adjacent to the product alignment apparatus 300.

Some embodiments of the bagging apparatus 700 of the present invention are described below in conjunction with fig. 43 through 47.

As shown in fig. 43, the bagging apparatus 700 includes a bag storage mechanism 710, a bag opening mechanism 720, and a bag opening mechanism 730. The bag storage mechanism 710 is configured to store folded bags, such as plastic bags, the bag opening mechanism 720 is configured to grasp the bags from the bag storage mechanism 710 and open them, and the bag expanding mechanism 730 is configured to receive the opened bags from the bag opening mechanism 720 and expand the opened bags into a predetermined shape, such as a substantially rectangular parallelepiped.

Here, the bag storage mechanism 710 is configured as a bag storage trough composed of a bottom plate and a plurality of limiting plates, and the folded bag is laid flat in the bag storage trough. The bag comprises a closed bag bottom and a bag opening to be opened.

In some embodiments, as shown in fig. 43, the bag opener 720 is configured to open the grasped bag such that the opened bag is open in a horizontal direction. Accordingly, the bag expanding mechanism 730 is configured to receive the bag opened toward the horizontal direction from the bag opening mechanism 720 and switch the received bag from the state opened toward the horizontal direction to the state opened vertically upward to receive the product. Due to the design, the bag opening mechanism 720 and the bag opening mechanism 730 can be arranged side by side in the horizontal direction, and therefore the bag sleeving device which is compact in the vertical direction is achieved.

In the exemplary embodiment shown in fig. 43, the bag-supporting mechanism 730 comprises a plurality of bag-supporting parts 731, for example four bag-supporting

parts

731a, 731b, 731c, 731d, which plurality of bag-supporting parts 731 is configured to be movable, in particular rotatable, in order to be able to open up a received bag into a predetermined shape. For example, when the bag opening mechanism 730 receives an opened bag, the bag opening portion 731 extends into the opened bag, and the bag is opened into a predetermined shape by the rotation of the bag opening portion 731.

Here, each pocket part 731 is configured as a pocket supporting bar, for example, each pocket supporting bar including a first bar part 7311 extending obliquely or perpendicularly to its rotational axis and a second bar part 7312 extending along its rotational axis.

Further, the bag supporting mechanism 730 includes a first supporting plate 732 and a second supporting plate 733. The plurality of supporting bag parts 731 are movably installed on the first supporting plate 732. The first support plate 732 is rotatably mounted on the second support plate 733 so that the bag supporting portions 731 of the first support plate 732 are rotatable between a bag receiving position shown in fig. 44, in which the plurality of bag supporting portions 731 are horizontally projected into the bag opened by the bag opening mechanism 720 and expand the bag into a predetermined shape, and a bag holding position shown in fig. 43, in which the expanded bag is held vertically upwardly open in a predetermined shape, so that the products can be put from above vertically downwardly into the vertically upwardly open bag supported by the bag supporting mechanism 730. For this purpose, for example, an insertion opening 7321 is opened on the first supporting plate 732, so that the product is vertically inserted into the bag opened by the bag opening mechanism 730 from above through the insertion opening 7321.

For example, a driving unit 737, such as an air cylinder driving unit or a motor driving unit, for driving the first supporting plate 732 to rotate between the bag receiving position and the bag holding position is mounted on the second supporting plate 733.

As shown in fig. 44, in order to drive the bag supporting portions 731 to rotate, for example, an independent rotation driving portion 734 may be provided on the first supporting plate 732 for each bag supporting portion 731, and the rotation driving portion 734 may be configured to drive the corresponding bag supporting portion 731 to rotate, so that the bag supporting portion 731 can open the bag. For example, the respective bag expanding portions 731 are capable of being brought together with each other by rotation of the respective rotary driving portions 734 so as to be extendable into the bag opened by the bag opening mechanism 720 and capable of being opened apart from each other so as to expand the bag into a predetermined shape.

Of course, in other embodiments, one rotation driving portion may be provided for a plurality of bag opening portions 731, which is not limited in the present invention.

Here, the rotation driving part 734 may include a cylinder driving structure or a motor driving structure, which is not particularly limited by the present invention.

In an alternative embodiment, the bag opener 720 is configured to open the grasped bag such that the opened bag opens vertically upward. Accordingly, the bag opener 730 is configured to receive a vertically upwardly open bag from the bag opener 720 and to hold the received bag vertically upwardly open to receive product. Such a design enables the bag opening mechanism 730 to be arranged above the bag opening mechanism 720, thereby realizing a horizontally compact bagging apparatus. At this time, the first support plate and the bag opening mechanism are configured to be movable relative to each other so that the plurality of bag opening portions can be extended into the bag opened by the bag opening mechanism in the vertical direction and open the bag into a predetermined shape.

As shown in fig. 43 and 44, the bag supporting mechanism 730 further includes a first supporting base 735, and the second supporting plate 733 is mounted on the first supporting base 735 in a manner movable in a vertical direction and/or movable in a horizontal direction. For example, the second support plate 733 is configured to be movable in a vertical direction so that the first support plate 732 mounted thereon, together with the bag supporting portion 731, can be moved in a vertical direction so that the bag supporting portion 731 can be aligned with the bag opening mechanism 720 to receive an opened bag.

In a specific example, as shown in fig. 44, a sliding rail 7351 extending vertically and a vertical driving assembly (e.g., a driving cylinder or a driving motor) 7352 are mounted on the first supporting base 735, the second supporting plate 733 is mounted on the first supporting base 735 in a manner of being movable along the sliding rail 7351, and the vertical driving assembly 7352 is used for driving the second supporting plate 733 to move along the sliding rail 7351.

In some embodiments, as shown in fig. 43, the bag opening mechanism 730 further comprises at least one auxiliary suction cup set 736, wherein the auxiliary suction cup set 736 is configured to suck the bag opened by the plurality of bag opening parts 731. For example, as shown in fig. 44, the bag supporting mechanism 730 includes a first auxiliary suction cup group 736a and a second auxiliary suction cup group 736b mounted on the first supporting plate 732 in opposition to each other, and the first auxiliary suction cup group 736a and the second auxiliary suction cup group 736b are respectively configured to be movable, particularly rotatable, so as to be able to turn the bag supported by the plurality of bag supporting portions 731 to thereby suck the bag from opposite sides.

In other embodiments, four auxiliary suction cup sets may be movably, and particularly rotatably, mounted on the first support plate 732 to hold the bag from four sides thereof.

Here, the auxiliary suction cup group 736 may include a plurality of vacuum suction cups or magnetic suction cups.

As shown in fig. 44 and 45, the bag opening mechanism 720 includes a bag taking assembly 721, a bag clamping assembly 722 and a bag opening assembly 723.

The bag taking assembly includes a bag taking suction cup group, such as a vacuum suction cup group 7211, and a suction cup driving portion 7212, the bag taking suction cup group 7211 being configured to suck the bag and being disposed above the bag storage mechanism 710, the suction cup driving portion 7212 being configured to drive the bag taking suction cup group 7211 to move in a vertical direction, so that the bag taking suction cup group 7211 can suck the bag bottom portion of the bag in the bag storage mechanism 710 up by a predetermined height in the vertical direction.

The bag clamp assembly 722 is configured to move in a horizontal direction so as to be movable from the bag bottom portion of the bag being sucked up by the bag pick cup set 7211 downwardly toward the bag mouth portion of the bag. The clip bag assembly 722 includes a clamping portion 7221 and a support plate 7222, the clamping portion 7211 being configured to clamp a mouth portion of the bag to the support plate 7222. Two clamping portions 7211 designed as clamping cylinders are provided here for pressing the bag mouth portions of the bags from both sides. The pouch gripper assembly 722 is movable, for example, by a driving unit 7223 along a horizontally extending rail 7224 toward the pouch mechanism 730.

The bag opening assembly 723 comprises an upper suction cup set, e.g., upper vacuum cup set 7231 and a lower suction cup set, e.g., lower vacuum cup set 7232, opposite each other and a second support seat 7233 on which the upper suction cup set 7231 and the lower suction cup set 7232 are mounted in a vertically movable manner relative to each other. Here, the bag clamping assembly 722 is further configured to convey the mouth portion of the clamped bag in a horizontal direction between the upper suction cup group 7231 and the lower suction cup group 7232 so that the upper suction cup group 7231 and the lower suction cup group 7232 can cooperate with each other to open the bag from the mouth portion of the bag.

In some embodiments, the upper suction cup set 7231 is configured to be vertically movable relative to the lower suction cup set 7232, while the lower suction cup set 7232 is configured to be vertically immovable. In other embodiments, the upper and lower suction cup sets 7231, 7232 are each configured to move in a vertical direction relative to each other.

In a further embodiment, the bag opening assembly is further configured to be movable in a horizontal direction relative to the bag opening mechanism 730 so that the opened bag can be transported to the bag opening mechanism 730.

An exemplary operation of the bagging apparatus 700 provided by the embodiment of the present invention is as follows: first, the suction cup driving part 7212 drives the bag taking suction cup group 7211 to move vertically downward so as to suck a bag bottom portion of one plastic bag from the bag storage mechanism 710, and then the suction cup driving part 7212 drives the bag taking suction cup group 7211 to move vertically upward so as to suck the bag bottom portion up by a predetermined height so that the bag bottom portion is located above a level where the bag clamping assembly 722 is located. The bag clamping assembly 722 holds the plastic bag from the bottom portion thereof below with its support plate 7222, slides in a horizontal direction up to the mouth portion of the plastic bag, and then clamps the mouth portion of the plastic bag to the support plate 7222 by means of the clamping portion 7221. Then, the bag clamping assembly 722 with the clamped plastic bag continues to move in the horizontal direction toward the bag opening assembly 723 until the clamped plastic bag is positioned with its mouth portion directly above the lower suction plate group 7232 so that the lower suction plate group 7232 sucks the mouth portion from below. Next, the upper suction cup group 7231 is moved downward in the vertical direction until it comes close to the mouth portion so as to suck the mouth portion from above. After the upper and lower

suction cup groups

7231 and 7232 suck the pocket portions from above and below, respectively, the clamp portions 7221 are released, and the pouch gripper assembly 722 moves back in the horizontal direction, returning to the original position. Then, the upper suction cup group 7231 is moved upward in a vertical direction to pull the mouth of the plastic bag open in cooperation with the lower suction cup group 7232. At the same time, the second support plate 733 is moved downward in the vertical direction, and then the first support plate 732 is turned 90 degrees to the left so that the bag supporting portion 731 is at the bag receiving position. Then, the bag opening assembly is moved in the horizontal direction toward the bag opening mechanism 730 to fit the opened plastic bag onto the bag opening portion 731 of the bag opening mechanism 730, and then the bag opening portion 731 is rotated to open and hold the plastic bag in a predetermined shape. After the bag opening part 731 opens the plastic bag, optionally, the first auxiliary suction cup group 736a and the second auxiliary suction cup group 736b rotate so that the suction cups thereof are turned to the plastic bag opened by the bag opening part 731, thereby assisting in holding the plastic bag from the opposite sides. The upper and lower cup sets 7231, 7232 are then released and the bag opener assembly 723 moves in a horizontal direction away from the bag opener mechanism 730 back to the initial position. Next, the second supporting plate 733 is moved upward in a vertical direction to a predetermined height, and then the first supporting plate 732 is turned downward by 90 degrees so that the pocket opening of the opened plastic bag is opened vertically upward, waiting for the product group to be put in.

In some embodiments, as shown in fig. 46, the bagging apparatus 700 is disposed on a support floor 750 below the bag-opening mechanism 730, the support floor 750 being configured to support bags, particularly bags containing product groups, that are opened by the bag-opening mechanism 730. Preferably, the support floor 750 comprises at least two flaps 151 which are configured to be overturnable between a support position and an output position, wherein the at least two flaps form a support surface in the support position for supporting the bag containing the product group and an output opening in the output position for enabling the bag-filled product group to be transported away through the output opening.

Fig. 47 shows an embodiment of a bag folding mechanism of the bagging apparatus according to the present invention. The bagging apparatus 700 includes a bag folding mechanism 740 disposed below the bag opening mechanism 730.

For example, the two bag folding bars 7411 are moved in the horizontal direction along the slide rails 7413 relative to the second bag folding assembly by a drive unit, such as a drive cylinder or a drive motor 7412. The two bag folding bars 7411 are moved in the vertical direction by a drive unit, for example, a drive cylinder or a drive motor 7414. The two tucker bars 7411 translate relative to each other under the drive of a drive, such as a drive cylinder or drive motor 7415.

The second folding assembly 742 includes a folding flap 7421 configured to be horizontally movable relative to the at least two folding bars 7411 to fold in a second side of the bag mouth. For example, the bag folding plate 7421 is moved in the horizontal direction along the slide rail 7423 relative to the first bag folding assembly by a drive unit, such as a drive cylinder or a drive motor 7422.

An exemplary operation of the bag folding mechanism 740 according to the embodiment of the present invention is as follows: after the product is assembled into the bag opened by the bag opening mechanism 730, the bag with the product group is supported on the support bottom plate 750, and the bag opening portion 731 of the bag opening mechanism 730 remains to open the bag. Then, the driving section 7412 drives the two bag folding bars 7411 to move toward the bag folding plate 7421 in the horizontal direction, while the

bag supporting portions

731a and 731b near the side of the bag folding bar 7411, i.e., near the first side of the bag opening, are rotated back (rotated close to each other) and the auxiliary suction cup group 736b near the first side of the bag opening is released, so that the bag folding bar 7411 can fold the first side of the bag opening. Subsequently, the driving section 7414 drives the two bag folding bars 7411 to move vertically upward, and then the driving section 7422 drives the bag folding plate 7421 to move toward the two bag folding bars 7411 in the horizontal direction, while the

bag supporting portions

731c and 731d near one side of the bag folding plate 7421, i.e., near the second side of the bag opening, are rotated back (rotated close to each other) and the auxiliary suction cup group 736a near the second side of the bag opening is released, so that the bag folding plate 7421 can fold the second side of the bag opening. Then, the driver 7415 drives the two bag folding bars 7411 to move close to each other and the driver 7414 drives the two bag folding bars 7411 to move vertically downward so as to draw in both sides adjacent to the first side of the bag opening. Subsequently, the driver 7422 drives the bag folding plate 7421 to move away from the two bag folding rods 7411 in the horizontal direction, and the bag folding operation is completed. Finally, when the additional movement mechanism reaches above the folded bag containing the product group, the driving portion 7412 drives the two bag folding rods 7411 to move back in the horizontal direction.
