Technical Field

[0001] The present invention relates to the technical field of packaging equipment, in particular to a packaging machine. Background Art

[0002] At present, in many fields, it is necessary to put a plurality of small packaging bags into a large packaging bag, and each small packaging bag contains and packages a packaged object such as food. For example, in the field of food processing, a packaging machine is needed specifically for putting a certain number of small packaging bags into a large packaging bag. Specifically, a certain number of small packaging bags are put into a large packaging bag, and each small packaging bag has contained and packaged foods such as betel nut and hairtail. Since a certain number of small packaging bags are piled together in a large packaging bag, they are relatively fluffy and loose without rules, and generally all the small packaging bags can be put into the large packaging bag by squeezing. Therefore, at present, for the situation where a plurality of small packaging bags need to be put into a large packaging bag in many fields including the field of food processing, manual packaging is adopted, which relies on manual counting of a predetermined number of small packaging bags, and then all the predetermined number of small packaging bags are put into a large packaging bag, which has the disadvantages of requiring a lot of labor, slow packaging speed and low work efficiency.

If there is no conflict, the various features in the embodiments and embodiments of the present invention can be combined with each other, all within the scope of protection of the present invention.

[0035] refer to Figures 1 to 5As an object of the present invention, a packaging machine is provided, which includes at least one packaging device. It should be noted that the packaging device can be arranged on a working platform, and preferably, more than two packaging devices are arranged on the same working platform. In order to balance cost and packaging efficiency, the present invention is described by taking two packaging devices as an example. The packaging device includes: a bag storage tank 1 for storing a plurality of first packaging bags, a transition tank 2 docked with the bag outlet of the bag storage tank 1, a guide tank 3 docked with the transition tank 2 to receive the first packaging bag that slides down from the transition tank 2, and a guide tank 3 for taking out the first packaging bag in the bag storage tank 1 and placing it on The bag taking assembly 4 in the transition groove 2, the positioning assembly 20 for positioning the first packaging bag that slides from the transition groove 2 into the guide groove 3 and sequentially preventing and allowing the first packaging bag to slide further, the bag opening assembly 5 for opening the positioned first packaging bag, the filling assembly 6 for supplying a plurality of second packaging bags each containing packaged objects into the inner cavity of the first packaging bag, the pushing assembly 7 for applying a pushing force to the second packaging bag in the filling assembly 6 to drop into the inner cavity of the first packaging bag, the delivery belt 8 located below and connected to the guide groove 3, and the sealing assembly 9 located downstream of the delivery belt 8 relative to the guide groove 3. The size of the above-mentioned second packaging bag is smaller than the size of the inner cavity of the first packaging bag. Specifically, the second packaging bag can be packaged with betel nut, hairtail fish, fish tofu, meat jerky and other foods as packaged objects, and the first packaging bag is equivalent to an outer packaging bag, so that a plurality of small packages of food are packaged in the first packaging bag, so that the quality of the food is preserved and it is convenient for users to eat in quantity. The sealing assembly 9 seals the first packaging bag that falls from the guide groove 3 onto the delivery belt 8 .The following further describes in detail the entire working process of the packaging machine for loading the second packaging bag into the first packaging bag. First, the bag taking component 4 takes out a first packaging bag from the bag storage slot 1 and puts it into the transition slot 2. Thereafter, the positioning component 20, for example, extends in the guide slot 3 to position the first packaging bag that slides into the guide slot 3 along the transition slot 2 to prevent the first packaging bag from further sliding. Then, the bag opening component 5 separates the two side surfaces of the positioned first packaging bag to open the bag. Next, the filling component 6 is used to supply a plurality of second packaging bags each containing a packaged object into the inner cavity of the opened first packaging bag. Next, the pushing component 7 applies a pushing force to the second packaging bag in the filling component 6, so that the plurality of second packaging bags are placed in the first The inner cavity of a packaging bag is compacted to ensure that the first packaging bag can accommodate a predetermined number of second packaging bags. It should be noted that if the inner cavity of the first packaging bag is large enough, each second packaging bag can also be directly dropped from the filling component 6 into the first packaging bag without configuring the pushing component 7 to apply the pushing force, but this will make the first packaging bag much larger than actually needed, which not only wastes materials but also has an adverse effect on subsequent transportation and user use. Therefore, the present invention has a beneficial technical effect that multiple second packaging bags are squeezed into the inner cavity of the first packaging bag through the pushing component 7 under the premise that the first packaging bag has a suitable size to reduce unnecessary material consumption, so as to package as many second packaging bags as possible. After the first packaging bag has accommodated a predetermined number of second packaging bags, the positioning component 20, for example, shortens the movement in the guide groove 3 to allow the first packaging bag to further slide onto the delivery belt 8 located below and opposite to the guide groove 3. Finally, the sealing component 9 seals the first packaging bag to seal each second packaging bag in the inner cavity of the first packaging bag.

[0036] Therefore, the present invention, by designing a packaging machine described above, can automatically load a predetermined number of second packaging bags with relatively small sizes into a second packaging bag with relatively large sizes and seal them without manual labor, thereby having the advantages of saving labor, fast packaging speed and high work efficiency.

[0037] Combined with reference Figure 6 and Figure 7Specifically, in one embodiment, the bag opening assembly 5 includes a bag opening assembly 51 and a bag bottom opening assembly 52. ​​The bag opening assembly 51 includes a first bag opening cylinder 511 and a first bag opening suction cup connecting plate 512 connected to each other, and a second bag opening cylinder 515 and a second bag opening suction cup connecting plate 516 connected to each other. A plurality of pairs of first bag opening suction cups 514 and second bag opening suction cups 517 opposite to each other are respectively arranged on the first bag opening suction cup connecting plate 512 and the second bag opening suction cup connecting plate 516. The first bag opening cylinder 511 and the second bag opening cylinder 515 drive the first bag opening suction cup connecting plate 511 to move the first bag opening suction cup connecting plate 512 to move the second bag opening suction cup connecting plate 516 ... first bag opening suction cup connecting plate 511 to move the second bag opening suction cup connecting plate 516 to move the first bag opening suction cup connecting plate 511 to move the first bag opening suction cup connecting plate 511 to move the first 2 and the second bag opening suction cup connecting plate 516 move between two positions close to each other and far away from each other. At the position close to each other, each pair of first bag opening suction cups 514 and second bag opening suction cups 517 move closer to each other to absorb the two opposite outer sides of the first packaging bag located therebetween. Then, from the position close to each other to the position far away from each other, each pair of first bag opening suction cups 514 and second bag opening suction cups 517 move away from each other to absorb the two opposite outer sides away from each other until they are completely separated and a bag opening with a maximum separation distance is obtained. The filling component 6 subsequently fills the first packaging bag through the bag opening. That is to say, Figure 6 As shown, the two bag opening cylinders extend and retract respectively so that the two bag opening suction cups respectively absorb the two opposite outer sides of the first packaging bag and make the distance between the two opposite outer sides large enough to facilitate the subsequent filling component 6 to fill the second packaging bag. The bag bottom opening component 52 includes a blow pipe translation cylinder 521 and a blow pipe connecting plate 522 connected to each other. A plurality of blow pipes 523 are arranged on the blow pipe connecting plate 522. When the two opposite outer sides are at the maximum separation distance, the blow pipe translation cylinder 521 drives the blow pipe connecting plate 522 to drive the blow pipe 523 to move to the top of the bag opening of the first packaging bag, and the blow pipe 523 blows air into the inside of the first packaging bag through the bag opening to blow open the bag bottom of the first packaging bag. Therefore, by configuring the bag opening component 5 to have the above-mentioned bag opening bag opening component 51 and bag bottom opening component 52, the bag bottom of the first packaging bag can be opened automatically and reliably, so as to facilitate the smooth loading of the second packaging bag into the first packaging bag.

[0038] Combined with reference Figure 8Specifically, in one embodiment, the packaging machine also includes a counting belt assembly 10, which includes a first counting belt, a second counting belt 105 and a third counting belt 106 that are adjacent to each other in sequence and sequentially convey the second packaging bag to the filling assembly 6, for example, a filling bucket 62 (which will be further described in detail below). The conveying speed of the second counting belt 105 is greater than the conveying speed of the first counting belt 101. By accelerating the second counting belt 105, the distance between the newly received second packaging bag on the second counting belt 105 and the second packaging bag on the first counting belt 101 can be widened. A first guide edge 102 and a second guide edge 103 are respectively provided on both sides of the first counting belt 101. A blocking block 104 is provided above the first counting belt 101. The gap formed between the blocking block 104 and the first counting belt 101 allows a single second packaging bag to pass through. In this way, the gap between the blocking block 104 and the first counting belt 101 can be adjusted by setting the blocking block 104, so that only a single second packaging bag is allowed to pass through the gap and be conveyed to the second counting belt 105. The packaging machine can further be provided with a return belt 22, and the second packaging bags blocked by the blocking block 104 will fall onto the return belt 22, and the second packaging bags collected from the return belt 22 will be put into the storage hopper 15 again to wait for being packaged into the first packaging bags. A counting detector 107 and an overlap detector 108 are provided above the third counting belt 106. The counting detector 107 is used to count the number of second packaging bags passing on the third counting belt 106, and the overlap detector 108 is used to detect the abnormal situation of the overlap area of ​​at least two second packaging bags. Since the two second packaging bags overlap in the vertical direction or the two second packaging bags are connected end to end without being separated, both belong to the abnormal situation of the overlap area. Therefore, the corresponding first packaging bag can be removed in the subsequent process by detecting the abnormal situation using the overlap detector 108.

[0039] Combined with reference Figures 9 to 11Specifically, in one embodiment, the filling assembly 6 is docked with the counting belt assembly 10 to collect the second packaging bags with a predetermined number conveyed by the counting belt assembly 10, and the filling assembly 6 includes a filling blocking hopper 61, a filling hopper 62, a filling translation cylinder 63, a filling translation plate 64, a filling connecting plate 65, a filling lifting cylinder 66, a filling switch plate cylinder 612, a block cylinder 67 and a filling hopper block 68. In this embodiment, the filling hopper 62 and the counting belt assembly 10 are both set to 4, which can speed up the filling speed of the second packaging bag into the first packaging bag or / and fill four different types of second packaging bags into the first packaging bag respectively and separately. A first filling switch plate 69 and a second filling switch plate 610 are provided below the filling hopper 62, and the first filling switch plate 69 and the second filling switch plate 610 are meshed with each other through a filling switch gear 611. A filling switch plate cylinder 612 is connected to the first filling switch plate 69, and the filling switch plate cylinder 612 can drive the first filling switch plate 69 and the second filling switch plate 610 to open and close. The second packaging bag conveyed from the third counting belt 106 falls into the filling hopper 62 under the obstruction of the filling blocking hopper 61, and the counting detector 10 When the number of the measured second packaging bags reaches the predetermined number, the filling translation cylinder 63 drives the filling translation plate 64 to move toward the first packaging bag in the guide groove 3, thereby driving the filling connecting plate 65, the filling lifting cylinder 66, and the filling bucket 62 connected to the filling translation plate 64 to move toward the first packaging bag in the guide groove 3 at the same time. When the filling bucket 62 reaches the top of the first packaging bag, the filling lifting cylinder 66 drives the filling connecting plate 65 and the filling bucket 62 fixed on the filling connecting plate 65 to move downward, thereby the first filling switch plate 69 and the second filling switch plate 610 The first packaging bag is inserted into the bag opening of the first packaging bag, and then each pair of the first bag opening suction cups 514 and the second bag opening suction cups 517 release the first packaging bag. At the same time, the first bag opening bag opening cylinder 511 and the second bag opening bag opening cylinder 515 drive each pair of the first bag opening suction cups 514 and the second bag opening suction cups 517 to move relatively away from each other to increase the distance between them, and the block cylinder 67 pushes the filling bucket block 68 to move, and the filling bucket block 68 presses the second packaging bag in the filling bucket 62. The filling switch plate cylinder 612, for example, drives the first filling switch plate 69 to open while also driving The second filling switch plate 610 is driven to open so that the two switch plates are opened at the same time to form a filling port. Specifically, the filling switch plate cylinder 612 can be driven and connected to the first filling switch plate 69, so that the filling switch plate cylinder 612 extends to drive the first filling switch plate 69 to open. Since the first filling switch plate 69 and the second filling switch plate 610 are meshed through the filling switch gear 611, when the first filling switch plate is opened, the second filling switch plate 610 is also opened synchronously, so that each second packaging bag is filled into the first packaging bag through the filling port.In this case, the filling assembly 6 can compress the second packaging bags with an accurate predetermined number conveyed by the counting belt assembly 10 in the filling hopper 62, thereby ensuring that each second packaging bag reliably falls into the first packaging bag.

[0040] Combined with reference Fig.12 and Fig.13 Specifically, in one embodiment, the pushing assembly 7 includes a pushing head assembly 71 and a connected pushing translation cylinder 72 and a pushing translation connecting plate 73. The pushing head assembly 71 includes a pushing motor 711, a pushing screw rod 712, a pushing nut 713, a pushing lifting plate 714 and a pushing head 715. The pushing translation cylinder 72 drives the pushing translation connecting plate 73 and the pushing head assembly 71 fixed on the pushing translation connecting plate 73 to move, so that the pushing head assembly 71 moves to the top of the filling bucket 62. It can be understood that, preferably, in the process of the counting belt assembly 10 conveying each second packaging bag to the filling bucket 62, the pushing head assembly 71 is driven by the pushing translation connecting plate 73 to be located outside the top of the filling bucket 62, so as to facilitate each second packaging bag to fall into the filling bucket 62 without obstacle, and when the predetermined After a certain number of second packaging bags have fallen into the filling hopper 62, the pushing head assembly 71 is driven by the pushing translation connecting plate 73 to be located above the filling hopper 62, so that on the basis of the first filling switch plate 69 and the second filling switch plate 610 being opened, the pushing head 715 can apply a pushing force on the second packaging bag to fall into the first packaging bag, so that each second packaging bag in the filling hopper 62 can fall into the first packaging bag faster and without omission, and the pushing motor 711 rotates to drive the pushing screw 712 to rotate, so that the pushing nut 713 matched with the pushing screw 712 moves downward and drives the pushing lifting plate 714 to move downward, and the pushing head 715 fixed under the pushing lifting plate 714 is driven to press and move toward the filling port, thereby pushing the second packaging bag in the filling hopper 62 to fall into the first packaging bag. Therefore, by setting up the pushing assembly 7, the pushing head assembly 71 can be driven to move horizontally relative to the filling bucket 62 with the help of the pushing translation link 73, and the pushing head 715 can be driven to move in and out relative to the filling bucket 62 in the vertical direction with the help of the pushing lifting, thereby ensuring that each second packaging bag is accurately and efficiently pushed into the first packaging bag.

The unloading hopper 111 is loaded with a plurality of additional materials. The unloading rack 112 is connected with each unloading hopper 111 and is provided with a chute 1121. When the first packaging bag is conveyed to the bottom of the unloading component 11 by the conveying belt 8, the material picking cylinder 113 drives the material picking suction cup 114 to move toward the corresponding unloading hopper 111 to absorb a preset additional material and then drives the material picking suction cup 114 in the opposite direction to move toward the chute 1121, so that the additional material slides along the chute 1121 into the first packaging bag. In this way, for some situations, it is necessary to put a plurality of additional materials into the first packaging bag. For example, additional materials such as promotional coupons, production certificates, points or blind box type collection cards, etc., the packaging machine of the present invention can automatically realize the loading of additional materials into the first packaging bag by setting a feeding component 11. In this embodiment, the additional materials are set as coupons and have 5 winning levels, so the feeding hoppers 111 of each feeding component 11 are set to 5 and the additional materials contained in each feeding hopper 111 are different from each other, and then the number of the material taking suction cups 114 is also set to 5 accordingly. In addition, the feeding detector 115 is set at the notch of the chute 1121 and is used to detect whether the additional materials slide correctly into the first packaging bag, that is, the feeding detector 115 can detect whether the additional materials slide and the correctness of the additional materials that slide is determined, for example, according to the number of winnings of each winning level. Therefore, if the feeding detector 115 detects that the additional materials are accurate winning levels, it is judged to be preset, and if it is inaccurate winning levels, it is judged not to be preset. In addition, the unloading assembly 11 may also be provided with an unloading lifting adjustment hand wheel 116 so as to adjust the height between the notch of the slide groove 1121 and the inner cavity of the first packaging bag.

When the delivery belt 8 sequentially conveys the first packaging bag under the two pressing components 12, the bag-moving lifting cylinder 121 corresponding to the pressing component 12 drives a pair of connected bag-moving cylinders 122 and bag-moving plates 123 to move downward, so that each bag-moving plate 123 moves to the first packaging bag. The first packaging bag is filled with a plurality of bags, and each bag-moving cylinder 122 drives the bag-moving plates 123 connected thereto to move away from each other. The pressing cylinder 125 drives the pressing head 126 to move into the first packaging bag to press the second packaging bag or the mixture of the second packaging bag and the additional material in the first packaging bag. Specifically, for the pressing component 12 located upstream of the material-discharging component 11, its pressing head 126 presses each second packaging bag, and for the pressing component 12 located downstream of the material-discharging component 11, its pressing head 126 presses each second packaging bag and the additional material in the first packaging bag. The pressing height adjustment hand wheel 124 is used to adjust the height of the bag-moving plate 123 and the pressing head 126 to adapt to the first packaging bag of different heights. In this way, by setting two pressing components 12, it is convenient to not only facilitate the additional material to fall into the first packaging bag, but also to ensure that there will be no obstruction from the second packaging bag or the additional material when the first packaging bag is subsequently sealed.

Each adjustment component can adopt an adjustment structure including a matching adjustment hand wheel and an adjustment rod to realize the corresponding adjustment function and can be obtained by referring to the relevant technical means in the field, which will not be repeated here. Therefore, the packaging machine of the present invention can not only adapt to first packaging bags of different widths by setting the first adjustment component 17 and the second adjustment component 18, but also adapt to first packaging bags of different heights by setting the third adjustment component 19. Therefore, the packaging machine has the advantage of being compatible with first packaging bags of various sizes.

[0046] Additionally, in one embodiment, nuts (not shown) that cooperate with the first sealing height adjustment screw rod 94 and the second sealing height adjustment screw rod 98 are respectively provided in the first sealing cylinder seat 91 and the second sealing cylinder seat 95, so that the first sealing knife 93 and the second sealing knife 97 can move up and down synchronously with the up and down movement of the first sealing cylinder seat 91 and the second sealing cylinder seat 95, respectively, so that the first sealing knife 93 and the second sealing knife 97 are both aligned with each other and adapt to first packaging bags of different heights.

[0051] Combined with reference Figure 4 and Figure 5 Specifically, in one embodiment, the positioning assembly 20 includes a positioning cylinder 201 and a positioning member 202 connected to each other. The positioning cylinder 201 drives the positioning member 202 to move into the guide groove 3 to support and position the first packaging bag so as to receive the filling of the second packaging bag. The positioning cylinder 201 drives the positioning member 202 to move away from the guide groove 3 to release the first packaging bag that has been filled by the second packaging bag so that it falls onto the delivery belt 8. In this way, the positioning assembly 20 ensures that the first packaging bag receives the filling operation at the correct position. In addition, preferably, the positioning assembly 20 is also provided with a bag detector 203 located above the positioning member 202, so as to accurately detect that the first packaging bag is accurately positioned in the guide groove 3 so as to receive the subsequent filling operation of the filling assembly 6.

The rejection assembly 21 includes a waste hopper 211, a connected rejection cylinder 212 and a rejection plate 213. When the above-mentioned overlap detector 108 detects an abnormality, the rejection cylinder 212 drives the rejection plate 213 to push the first packaging bag away from the delivery belt 8 and move to the waste hopper 211. This effectively prevents the unqualified first packaging bag from being mistakenly regarded as a qualified finished product, thereby improving the finished product yield of the packaging machine.

[0053] It should be noted that the embodiments of the present invention all adopt two packaging devices. Accordingly, the delivery belt 8 moves two workstations each time, that is, the distance between two first packaging bags each time. In this way, the pressing component 12, the unloading component 11, and the sealing component 9 need to be adaptively arranged as two parallel groups, thereby taking into account both cost and packaging efficiency.
