Description

A method and equipment for online packaging of goods with cushioning bags Technical Field

[0001] This invention relates to the field of express logistics, and more specifically, to a method and apparatus for online packaging of goods using cushioning bags. Background Technology

[0002] There are many types of cushioning materials, one of which uses slotted sheets. Slotted sheet a, as shown in Figure 1, consists of multiple slots arranged in rows on a sheet. A slot is a cut that separates the paper. Slots in the same row are spaced apart, and slots in adjacent rows are staggered. The length of the slots, the spacing between slots in the same row, and the spacing between adjacent rows are all the same. When this slotted sheet is subjected to an external force perpendicular to the slot direction, it is stretched and transforms into a mesh structure with three-dimensional openings. This changes the original thickness of the sheet by several times, forming a cushioning layer. The expansion of the cushioning layer in the thickness direction provides the cushioning effect. Commonly used materials for this type of sheet are plastic or paper.

[0003] Figure 2 is a side sectional view of the packaging bag 10a. The packaging bag made using the aforementioned cushioning sheet a includes an outer bag body b having a first side, and a slit sheet a located inside the outer bag body b. The slit sheet a is fixed to the two inner surfaces of the opening c of the outer bag body, and the bottom of the slit sheet a is suspended inside the outer bag body b. At this time, the thickness of the packaging bag is only the thickness of the outer bag body plus twice the thickness of the slit sheet.

[0004] When using this type of packaging bag, the slit sheet needs to be pushed along the direction in which the item is placed, thus opening or stretching the slit sheet. After opening, the slit sheet forms a three-dimensional mesh structure inside the packaging bag, increasing its thickness by 3-12 times or more, creating a cushioning layer with shock-absorbing properties. This cushioning layer effectively protects the packaged item after it is placed inside. During transportation, the cushioning layer remains in its unopened or unstretched slit sheet state, thus saving on transportation costs due to its smaller thickness. When in use, external force pushes the bag, causing it to expand in the thickness direction, increasing its thickness.

[0005] When using such cushioning bags to package items, the existing technology involves manually pushing and opening the slit sheet to create a cushioning layer. This involves placing the packaged item into the bag opening and pushing it to open the slit sheet. However, this method is inefficient. Furthermore, manually opening the slit sheet requires considerable force to push the slit plane to the bottom of the outer bag. Since the bottom of the bag has limited space, resistance increases. Often, due to variations in the force and angle applied, the entire slit sheet cannot be opened, failing to achieve optimal cushioning protection. For example, the slit may not open thick enough, reducing the cushioning effect; or the slit may not be fully stretched into a three-dimensional opening, failing to completely cover the entire outer bag, resulting in defects.

[0006] In addition, when packing items inside cushioning bags, the current method is manual loading, which is inefficient. If the items to be packed are of different sizes, it is necessary to manually select cushioning bags of different sizes, which further reduces the loading efficiency. Summary of the Invention

[0007] The purpose of this invention is to provide a method and apparatus for online packaging of goods using cushioning bags, aiming to solve the technical problem of low efficiency in manually opening slit sheets in the prior art.

[0008] This invention provides a method for online packaging of items using a cushioning bag. The cushioning bag includes a slit sheet and a first surface, wherein both ends of the slit sheet are respectively connected to both ends of the first surface.

[0009] The two ends of the first side form the opening of the cushioning bag between each other.

[0010] The method is used for packaging items in cushioned packaging bags, including:

[0011] Step S1: Place the cushioning packaging bag at the loading position;

[0012] Step S2: Convey the items to be packaged;

[0013] Step S3: Grab or place the cushioning packaging bag from the feeding position and convey it to the packaging position; before the cushioning packaging bag moves to the packaging position, push or stretch the cushioning sheet to change it into the cushioning pad, with the pushing or stretching direction from the bag opening towards the bottom of the bag;

[0014] Step S4: After the cushioning bag moves to the packaging position, the bag opening faces the item to be packaged; when the packaging position is stationary relative to the item to be packaged, the cushioning bag moves the item to be packaged towards the bottom of the bag, so that the item to be packaged is put into the cushioning bag.

[0015] The method disclosed in this invention can package items online and push the slit sheet to form a three-dimensional mesh structure of cushioning pad before packaging, thereby overcoming the problem of low efficiency in existing manual operation techniques.

[0016] In step S1 of the present invention: the buffer packaging bags on the feeding position are of various types, and at least two types of the buffer packaging bags have different sizes;

[0017] Meanwhile, step S3 includes:

[0018] Step S31: Before picking up or placing the item to be packaged, identify the size of the item to be packaged;

[0019] Step S32: After identifying the size of the item to be packaged, grab or place a cushioning bag that is adapted to the size of the item to be packaged, so that the cushioning bag corresponds one-to-one with the item to be packaged.

[0020] Furthermore, the method of this invention can automatically select a cushioning bag of the appropriate size to achieve packaging based on the dimensions of the item to be packaged. Additionally, before entering the equipment, it is only necessary to manually or automatically place the item to be packaged and the cushioning bag of different sizes into the equipment.

[0021] The present invention also discloses an apparatus for online packaging of articles with cushioning bags, the apparatus comprising:

[0022] The loading position is installed on the machine platform, and the loading position is equipped with a storage bag bin, which is used to stack and place the cushioning packaging bags.

[0023] A packaging position is provided on the machine platform, and the packaging position is relative to the item to be packaged.

[0024] A gripping and conveying unit, installed on the machine base, is used to grip and convey the cushioning packaging bag from the loading position to the packaging position;

[0025] The feeding belt, installed on the machine base, is used to transport items to be packaged;

[0026] The bag opening module includes a telescopic component, which is positioned relative to the opening of the cushioned packaging bag. The telescopic component is controlled to move from the opening toward the bottom of the bag to push or stretch the cushioning sheet of the cushioned packaging bag to form a cushioning pad before the cushioned packaging bag is conveyed to the packaging position.

[0027] A bagging module is located on one side of the packaging position and is positioned relative to the bag opening, for pushing the item to be packaged on the feeding belt into the cushioning packaging bag located at the packaging position;

[0028] The bag-opening module controls the pushing depth or distance of the telescopic component according to the size of the cushioning packaging bag; the bag-filling module controls the pushing depth or distance of the item to be packaged into the cushioning packaging bag according to the size of the item to be packaged.

[0029] The device of this invention places a cushioning packaging bag in a storage bin. A gripping and conveying unit grips and conveys the cushioning packaging bag from the storage bin to the packaging position. During conveying, an opening module pushes the slit sheet of the cushioning packaging bag, transforming it into a cushioning pad. After the cushioning packaging bag is conveyed to the packaging position, the item to be packaged, corresponding to the cushioning packaging bag, is pushed into the cushioning packaging bag by a bagging module. The entire process is simple and convenient, and it can achieve the corresponding loading of the item to be packaged into the cushioning packaging bag. It is particularly suitable for use in the express packaging field. For example, the model, contents, size, and express information of the item to be packaged can be marked on the corresponding cushioning packaging bag, such as by affixing information codes.

[0030] In this invention, the bag opening module can adaptively control the pushing depth or distance of the telescopic component according to the size of the cushioning packaging bag, thereby enabling the cushioning packaging bag to have maximum cushioning performance.

[0031] The bagging module can also control the depth and distance of pushing the item into the cushioning bag according to the size of the item to be packaged, ensuring that each item can be completely packed into the cushioning bag. Attached Figure Description

[0046] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0047] As shown in Figure 3, the cushioning packaging bag B of the present invention includes a slit sheet b1 and an outer bag body b6. The slit sheet b1 is located inside the outer bag body b6. The outer bag body b6 includes a bag opening b2 and a bag bottom b3. The bag bottom b3 is opposite to the bag opening b2. When the slit sheet b1 is pushed or stretched, it expands in the thickness direction to form a cushioning pad b5, thereby giving the cushioning packaging bag B cushioning performance. The cushioning packaging bag B has two side edges b4, which are opposite to each other and are located on both sides of the bag opening b2.

[0048] As shown in Figures 3 and 4, the method for online packaging of articles using cushioning bags according to the present invention includes:

[0049] Step S1: Place the cushioning bag in the loading position; this step is equivalent to loading the cushioning bag. During loading, the cushioning bag can include one size or multiple sizes. If the cushioning bag has multiple sizes, the loading position can be equipped with storage compartments of different sizes. The cushioning bag is then placed into the appropriate storage compartment according to its size.

[0050] Step S2: Convey the items to be packaged. The items to be packaged can be of the same size, and the buffer bags at the loading station can also be of the same size. When the items to be packaged are of different sizes, the buffer bags at the loading station can be of different sizes, but it can be ensured that all sizes of items to be packaged can be packed into the largest size buffer bag.

[0051] Step S3: Grab or place the cushioning packaging bag from the feeding position and convey it to the packaging position; before the cushioning packaging bag moves to the packaging position, push or stretch the cushioning sheet to change it into the cushioning pad, with the pushing or stretching direction from the bag opening toward the bag bottom.

[0052] In this invention, a cushioning bag is conveyed to the packaging position. Before the items to be packaged are placed in the packaging position, the cushioning sheet inside the cushioning bag is pushed or stretched to form a cushioning pad with cushioning properties. The pushing or stretching can be implemented at a fixed position between the loading position and the packaging position; or it can be implemented during the conveying process, while the cushioning bag is relatively stationary but moves relative to the loading position.

[0053] When the buffer packaging bags on the feeding station have various different sizes and specifications

[0054] Step S3 further includes:

[0055] Step S31: Before picking up or placing the item to be packaged, identify the size of the item to be packaged;

[0056] Step S32: After identifying the size of the item to be packaged, grab or place a cushioning bag that is adapted to the size of the item to be packaged, so that the cushioning bag corresponds one-to-one with the item to be packaged.

[0057] In other words, when transporting items to be packaged, the size of the items to be packaged is identified, and then a cushioning bag of the corresponding size is selected and transported according to the identified size data. When the cushioning bag is transported to the packaging position, it corresponds exactly to the corresponding item to be packaged of the identified size, thus ensuring that items of different sizes can be loaded into the appropriate cushioning bag one by one.

[0058] In this method, identifying the size of the item to be packaged includes at least one of the following methods:

[0059] Step S311: Capture image data of the item to be packaged, and obtain the size information of the item to be packaged based on the image data.

[0060] or

[0061] When an identification code is set on the item to be packaged, the identification code indicates the size information of the item to be packaged, or the identification code leads to a database for retrieving the size of the item to be packaged; Step S311: Identify the identification code to obtain the size information of the item to be packaged.

[0062] In this invention, when pushing or stretching the buffer sheet, step S3 further includes:

[0063] Step S33: Based on the size information of the item to be packaged and / or the cushioning packaging bag, control the pushing or stretching depth or distance to push or stretch the cushioning sheet to change it into the cushioning pad.

[0064] In this invention, the depth of pushing or stretching is controlled according to the size of the identified cushioning packaging bag, which enables the cushioning pad inside the cushioning packaging bag to have the maximum stretching depth, while also preventing the outer bag from breaking due to excessive pushing or stretching depth.

[0065] In this invention, when the cushioning sheet is pushed or stretched, the bag opening is opened or fixed, and / or the two sides are clamped to position the cushioning packaging bag. When the cushioning sheet is pushed, a telescopic component extending into the bag opening pushes the cushioning sheet, causing the cushioning sheet to move from the bag opening toward the bottom of the bag, thereby stretching the cushioning sheet to form a cushioning pad.

[0066] The open or fixed bag opening allows the telescopic component to easily extend into the bag, facilitating the pushing or stretching of the cushioning bag and preventing contact between the telescopic component and the bag opening during pushing, which could damage the outer bag body. The fixed bag opening and the two clamping sides ensure that the position of the cushioning bag is fixed relative to the telescopic component, making the pushing or stretching process smoother and easier to control the pushing depth.

[0067] Step S4: After the cushioning bag moves to the packaging position, the bag opening faces the item to be packaged; when the packaging position is stationary relative to the item to be packaged, the cushioning bag moves the item to be packaged towards the bottom of the bag, so that the item to be packaged is put into the cushioning bag.

[0068] Step S4 includes:

[0069] Step S41: Open or secure the bag opening; and / or

[0070] Step S42: Clamp the two sides and position the opening of the cushioning bag relative to the item to be packaged;

[0071] Step S43: Push the item to be packaged into the bag opening.

[0072] The open or fixed bag opening facilitates the insertion of the item to be packaged into the cushioning bag, preventing contact between the item and the bag opening during insertion and thus avoiding damage to the outer bag. The fixed bag opening and the two clamping sides ensure that the cushioning bag is positioned relative to the item to be packaged, making it easy to insert the item into the cushioning bag.

[0073] In this invention, the method further includes:

[0074] Step S5: Identify the type of the item to be packaged and / or affix the corresponding information code to the cushioning bag according to the item type and / or express delivery information marked on the QR code on the item to be packaged.

[0075] The information coding can be applied before the cushioning bag is conveyed to the packaging position, or it can be applied after the items to be packaged are placed inside the cushioning bag.

[0076] Step S6: Seal the bag opening.

[0077] The method disclosed in this invention can package items online and push the slit sheet to form a three-dimensional mesh structure of cushioning pad before packaging, thereby overcoming the problem of low efficiency in existing manual operation techniques.

[0078] Furthermore, the method of this invention can automatically select a cushioning bag of the appropriate size to achieve packaging based on the dimensions of the item to be packaged. Additionally, before entering the equipment, it is only necessary to manually or automatically place the item to be packaged and the cushioning bag of different sizes into the equipment.

[0079] As shown in Figure 5, the present invention also discloses a device 100 for online packaging of articles using cushioning bags, the device comprising:

[0080] 1. Loading position 10 and storage bag hopper 10a

[0081] As shown in Figure 5, the feeding position is installed on machine A, and the feeding position 10 is provided with a storage bag bin 10a, which is used to stack and place the cushioning packaging bags B.

[0082] The material loading position 10 may have one storage bin 10a, or multiple bins may be provided depending on the size and specifications of the cushioning packaging bags B. The size of the cushioning packaging bags B placed in the two storage bins 10a may not be exactly the same.

[0083] As shown in Figure 6, the storage bag compartment 10a includes a guide rod 110 and a support surface 120.

[0084] Specifically, there are multiple guide rods 110, which are arranged perpendicular to the machine base A. The cushioning packaging bags B are stacked in the area between the multiple guide rods 110, and the guide rods 110 are used to limit the position of the cushioning packaging bags B. The support surface 120 protrudes from the guide rods 110 and is used to support the cushioning packaging bags B placed between the multiple guide rods 110.

[0085] 2. Packaging position 20

[0086] As shown in Figure 5, the packaging position 20 is set on the machine A, and the packaging position 20 is relative to the item C to be packaged; the packaging position 20 is located at the rear end of the feeding position 10 in the conveying direction; after the cushioning packaging bag B is conveyed to the packaging position 20, the item C to be packaged is put into the cushioning packaging bag B at the packaging position 20.

[0087] 3. Feeding belt 30

[0088] As shown in Figure 5, the feeding belt 30 is installed on the machine A and is used to transport the item C to be packaged. The item C is put into the feeding belt 30 from the front end of the conveyor. As the feeding belt 30 is conveyed, it is transported to the packaging position 20, where the item C is put into the buffer packaging bag B.

[0089] In this invention, the conveying of the item to be packaged C and the cushioning bag B are independent, but the time taken for them to be conveyed from the position corresponding to the loading position 10 to the position corresponding to the packaging position 20 is the same. That is, the time it takes for the item to be packaged C to be conveyed from the position corresponding to the loading position 10 to the packaging position 20 is the same as the time it takes for the cushioning bag B to be conveyed after being picked up from the loading position 10, during which, for example, labels are affixed, the cushioning sheet b1 is pushed or stretched, until it reaches the packaging position 20. This ensures that each item to be packaged C corresponds to a cushioning bag B of the corresponding size that is picked up.

[0090] 4. Bag opening position 40 and bag opening module 40a

[0091] As shown in Figure 5, the bag opening position 40 is located between the feeding position 10 and the packaging position 20; the gripping and conveying unit 80 is used to convey the cushioning packaging bag B to the bag opening position 40, and the cushioning sheet b1 of the cushioning packaging bag B is pushed or stretched at the bag opening position 40 to form the cushioning pad b5.

[0092] The bag opening module 40a is located on one side opposite the bag opening position 40. The bag opening module 40a pushes or stretches the cushioning sheet b1 of the cushioning packaging bag B at the bag opening position 40. The bag opening module 40a includes a telescopic component 410. The bag opening module 40a is disposed relative to the bag opening b2 of the cushioning packaging bag B. The telescopic component 410 is controlled to move from the bag opening b2 toward the bag bottom b3, so as to push or stretch the cushioning sheet b1 of the cushioning packaging bag B to form a cushioning pad b5 before the cushioning packaging bag B is conveyed to the packaging position 20.

[0093] The bag opening module 40a controls the pushing depth or distance of the telescopic component 410 according to the size of the cushioning packaging bag B.

[0094] In this invention, the bag opening module 40a is arranged relative to the bag opening position 40, as shown in Figures 7 and 8 and in conjunction with Figure 5. The telescopic component 410 includes a push plate 411 and a toothed portion 412 disposed on the side of the push plate 411 perpendicular to the conveying direction. The toothed portion 412 includes a plurality of spaced grooves 4121, which are distributed along the length direction of the push plate 411.

[0095] The bag opening module 40a further includes a drive shaft 420 and a drive gear 430.

[0096] The drive shaft 420 is arranged along the conveying direction. The drive shaft 420 is driven by the first drive motor 440 to rotate or stop. The first drive motor 440 is arranged on the machine base A. The drive gear 430 is sleeved on the drive shaft 420 and rotates with the drive shaft 420 and stops when the drive shaft 420 stops. The drive gear 430 includes a plurality of protruding teeth 4301 distributed on the outer peripheral surface.

[0097] At least one of the protruding teeth 4301 is located in the groove 4121. When the first drive motor 440 rotates, the drive gear 430 rotates so that the protruding teeth 4301 push the groove 4121, thereby realizing the extension and retraction of the push plate 411.

[0098] Referring to Figures 7 and 8, in another embodiment, there are two push plates 411, which are individually controlled by two drive shafts 420 and two first drive motors 440, and are arranged side by side or stacked. The width of the two push plates 411 extending at the same time is greater than the width of a single push plate 411. The bag opening module 40a selects to push one or two push plates 411 according to the size of the cushioning packaging bag B to accommodate cushioning packaging bags B of different sizes.

[0099] 5. Bagging module 50

[0100] As shown in Figure 5, the bagging module 50 is located on one side of the packaging position 20 and is positioned relative to the bag opening b2. It is used to push the item C to be packaged on the feeding belt 30 into the cushioning packaging bag B located on the packaging position 20. The bagging module 50 controls the depth or distance of pushing the item C into the cushioning packaging bag B according to the size of the item C to be packaged.

[0101] As shown in Figures 9 and 10 and in conjunction with Figure 5, the bagging module 50 of this invention includes: a bracket 510, a baffle 520, a fourth slide rail 530, a slider 540, a second drive motor 550, and a vertical plate 560.

[0102] The support 510 is disposed at the conveying end of the feeding belt 30, and the support 510 has a receiving space 511 into which the item C to be packaged is conveyed from the feeding belt 30. The baffle 520 is disposed on the support 510 to prevent the item C to be packaged from moving further on the feeding belt 30.

[0103] The fourth slide rail 530 is mounted on the bracket 510 and is perpendicular to the conveying direction; the slider 540 is slidably mounted on the fourth slide rail 530; the second drive motor 550 is connected to the slider 540 through a transmission structure 570, and when the second drive motor 550 rotates, it drives the slider 540 to move toward or away from the packaging position 20; one end of the vertical plate 560 is mounted on the slider 540, and the other end is located in the accommodating space 511.

[0104] After the item C to be packaged is conveyed to the receiving space 511, the vertical plate 560 abuts against the side of the item C away from the packaging position 20, and the second drive motor 550 drives the slider 540 and the vertical plate 560 to push the item C to be packaged into the buffer packaging bag B on the packaging position 20.

[0105] 6. Discharge belt 60

[0106] As shown in Figures 5 and 11, the discharge belt 60 is located at the rear end of the gripping and conveying unit 80. The gripping and conveying unit 80 conveys the cushioning packaging bag B containing the item C to be packaged to the discharge belt 60, and the discharge belt 60 is used to output the cushioning packaging bag B.

[0107] The discharge belt 60 is connected to a receiving tray 610, which is located at the rear end of the gripping and conveying unit 80 and at the front end of the discharge belt 60. The receiving tray 610 receives cushioning bags B, which already contain items C to be packaged, from the gripping and conveying unit 80. When the cushioning bag B is placed on the receiving tray 610 by the gripping and conveying unit 80, at least a portion of the cushioning bag B contacts the discharge belt 60 and is located on its upper surface. The continuously fed discharge belt 60 carries the cushioning bag B out of the discharge belt 60, where it is then packaged and transported to the logistics system.

[0108] 7. Sealing module 70

[0109] The sealing module 70 is disposed at the packaging position 20 or at the rear end of the conveyor of the packaging position 20. The sealing module 70 is used to press and seal the opening b2 of the cushioning packaging bag B. That is, the sealing module 70 can be installed on the bagging module 50 or installed separately at the rear end of the bagging module 50. When the sealing module 70 is installed on the bagging module 50, after the bagging module 50 pushes the item C to be packaged into the cushioning packaging bag B, the sealing module 70 starts to work, seals the cushioning packaging bag B, and then it is conveyed to the discharge belt by the gripping conveyor unit 80. When the sealing module 70 is installed at the rear end of the bagging module 50, after the bagging module 50 puts the item C to be packaged into the cushioning bag B, the gripping and conveying unit 80 conveys the cushioning bag B into the sealing module 70, the sealing module 70 seals the bag opening b2, and then the gripping and conveying unit 80 conveys the cushioning bag B into the discharge belt 60.

[0110] As shown in Figures 5 and 12, in this invention, the sealing module 70 includes a telescopic rod 710. The telescopic rod 710 is perpendicular to the plane of the conveying direction, and its position corresponds to the opening of the cushioning packaging bag B on the packaging position 20. When the item to be packaged C is placed inside the cushioning packaging bag B, the telescopic rod 710 extends and presses against the opening b2 of the cushioning packaging bag B. At this time, the gripping conveyor unit 80 conveys the cushioning packaging bag B to the discharge belt 60, and the opening b2 slides relative to the telescopic rod 710, thereby using the telescopic rod 710 to adhere the adhesive at the opening b2, thus achieving sealing.

[0111] 8. Grabbing and conveying unit 80

[0112] As shown in Figure 5, the gripping and conveying unit 80 is installed on the machine base A and is used to grip and convey the buffer packaging bag B from the storage bag bin 10a to the packaging position 20, as well as the discharge belt 60.

[0113] The gripping and conveying unit 80, positioned below the loading position 10 (or, in other words, below the storage bin 10a), adsorbs or grips the cushioning packaging bag B, thereby gripping the cushioning packaging bag B sequentially from bottom to top. After gripping or adsorbing the cushioning packaging bag B, the gripping and conveying unit 80 causes the cushioning packaging bag B to detach from the supporting surface and be conveyed from below the storage bin 10a. The gripping and conveying unit 80 then conveys the cushioning packaging bag B toward the packaging position 20.

[0114] The gripping and conveying unit 80 may include multiple modules that grip and convey the cushioning packaging bag B in a segmented relay manner. For example, after one module grips and conveys the cushioning packaging bag B from the storage bin 10a to a certain position, another module continues to convey the cushioning packaging bag B from the last position of the previous module to the packaging position 20 or the discharge belt 60. When the next module conveys the cushioning packaging bag B, the previous module returns to the loading position 10 to grip and convey the next cushioning packaging bag B; after the next module conveys the cushioning packaging bag B to the packaging position 20, or after the item to be packaged C is loaded into the cushioning packaging bag B, it returns to the last position of the previous module to continue conveying. This segmented relay conveying method of the gripping and conveying unit can maximize the conveying efficiency and can adapt to situations where the distance between the loading position and the packaging position is large, making it more convenient.

[0115] In this invention, the structure or method by which the gripping and conveying unit 80 conveys the cushioning packaging bag B to the packaging position 20 should be considered as within the scope of protection of this application.

[0116] As shown in Figure 5, in this invention, when there are multiple storage bins 10a, the device 100 includes a vision inspection module 30a, which is used to detect and identify the size and / or category of the items C to be packaged located on the feeding belt 30.

[0117] Specifically, the visual inspection module 30a is used to take pictures of the items to be packaged, and then process the pictures to obtain the dimensions of the items to be packaged C, including:

[0118] Method 1: Based on the image content, identify and determine the size and specifications of the item to be packaged, thereby obtaining the size information of the item to be packaged.

[0119] Method 2: The item to be packaged is marked with an identification code, which indicates the size information of the item to be packaged, or the identification code leads to a database for retrieving the size of the item to be packaged; the identification code is identified from the photographed image, and the size specifications of the item to be packaged are obtained directly or from the database, thereby obtaining the size information of the item to be packaged.

[0120] In this invention, the gripping and conveying unit 80 grips the cushioning packaging bag B from the corresponding loading position 10 according to the size of the item C to be packaged. The gripped cushioning packaging bag B is adapted to the size of the item C to be packaged, so that the cushioning packaging bag B and the item C to be packaged correspond one-to-one at the packaging position 20.

[0121] In this invention, when conveying the item C to be packaged, the size of the item C to be packaged is identified, and then a cushioning bag B of the corresponding size is selected for conveying according to the identified size data. When the cushioning bag B is conveyed to the packaging position 20, it corresponds exactly to the corresponding item C to be packaged of the identified size, thereby ensuring that items C of different sizes can be loaded into the corresponding cushioning bag B.

[0122] As shown in Figures 13 and 14, in this invention, the gripping and conveying unit 80 includes a support plate 801, which is located below the loading position 10 and the packaging position 20. The support plate 801 is arranged from the loading position 10 to the packaging position 20. The support plate 801 is used to support the cushioning packaging bag B placed on it, and the cushioning packaging bag B can move or remain stationary on the support plate 801.

[0123] In this invention, the cushioning packaging bag B is located on the support plate 801 throughout the entire conveying process. There are two support plates 801, which are arranged in parallel and have a gap L between them. The support plates 801 are arranged along the conveying direction.

[0124] In this invention, the gripping and conveying unit 80 includes a gripping module 81 as shown in FIG13 and a conveying module 82 as shown in FIG14; the gripping module 81 is used to grip the cushioning packaging bag B and convey the cushioning packaging bag B along the support plate 801 to the conveying module 82; the conveying module 82 is used to convey the cushioning packaging bag B from the gripping module 81 along the support plate 801 to the bag opening position 40 and the packaging position 20.

[0125] As shown in Figure 15, in one embodiment of the present invention, the device further includes: a labeling position 90 and a labeling module 90a.

[0126] The labeling position 90 is located between the loading position 10 and the opening position 40. The gripping module 81 is used to transport the cushioning packaging bag B from the loading position 10 to the labeling position 90. The conveying module 82 is used to transport the cushioning packaging bag B from the labeling position 90 to the opening position 40 and the packaging position 20. The labeling module 90a is used to affix information codes to the cushioning packaging bag B. The information codes record the type of the item to be packaged and / or express delivery information.

[0127] As shown in Figure 13, in this invention, the gripping module 81 includes: a first slide rail 810, a first sliding plate 811, and a first adsorption structure 812. Specifically, the first slide rail 810 is disposed on the machine platform A along the conveying direction; the first sliding plate 811 is slidably connected to the first slide rail 810, and the first sliding plate 811 is controlled to slide or stop on the first slide rail 810; the first adsorption structure 812 is fixed to the first sliding plate 811, and the first adsorption structure 812 includes at least two first suction cups 8121, the first suction cups 8121 being disposed facing the cushioning packaging bag B, for adsorbing the cushioning packaging bag B.

[0128] Wherein, after the first adsorption structure 812 adsorbs the buffer packaging bag B, it pulls the buffer packaging bag B away from the feeding position 10; after the buffer packaging bag B is removed from the feeding position 10, the first sliding plate 811 is located on the support plate 801 and slides along the first slide rail 510 for conveying.

[0129] As shown in Figure 13 and Figure 15, the first adsorption structure 812 is in an adsorption state during the movement of the cushion packaging bag B. When the first adsorption structure 812 conveys the cushion packaging bag B to the receiving position of the conveying module 82, it is in a release state, thereby facilitating the conveying module 82 to relay the cushion packaging bag B. The receiving position of the conveying module 82 is also the labeling position 90. At this time, after the first adsorption structure 812 conveys the cushion packaging bag B to the labeling position 90 along with the first sliding plate 811, the labeling module 90a affixes the information code to the cushion packaging bag B. Then, the first adsorption structure 812 releases the cushion packaging bag B. After the conveying module 82 moves from the rear end of the conveying process to the labeling position 90, it conveys the cushion packaging bag B to the opening position 40 and the packaging position 20.

[0130] In this invention, the conveying module has different implementations, namely, implementation one and implementation two.

[0131] Implementation Method 1

[0132] As shown in Figure 14, the conveying module 82 includes only the first module 82a, which is located at the rear end of the gripping module 81. The first module 82a is used to convey the buffer packaging bag B released from the gripping module 82 and to convey the buffer packaging bag B to the opening position 40 and the packaging position 20 respectively.

[0133] The first module 82a includes: a second slide rail 821, a second sliding plate 822, two third slide rails 823, and two sliding rods 824.

[0134] Specifically, the second slide rail 821 is disposed on the machine platform A along the conveying direction; the second sliding plate 822 is slidably connected to the second slide rail 821, and the second sliding plate 822 is controlled to slide or stop on the second slide rail 821; the third slide rail 823 is perpendicular to the plane of the conveying direction, and the third slide rail 823 is disposed on the second sliding plate 822, with the two third slide rails 823 facing each other; two sets of sliding rods 824 are slidably connected to the third slide rails 823 respectively, each set of sliding rods 824 has two, the two sliding rods 824 in the same set are facing each other and are respectively disposed on the upper and lower sides of the support plate 801, and the sliding rods 824 are provided with multiple pressure rods 825 at intervals along the length direction, each pressure rod 825 being perpendicular to the cushioning packaging bag B.

[0135] In this configuration, each set of sliding rods 824 corresponds to two sides b2 of the cushioning packaging bag B, and the second sliding plate 822 is controlled to move in the conveying direction; the sliding rods 824 are controlled to slide in a direction perpendicular to the plane where the cushioning packaging bag B is located; the pressure rods 825 on the same set of sliding rods 824 are used to press one of the two sides b2, and the pressure rods 825 on the two sets of sliding rods 824 are used to press the two sides b2 respectively.

[0136] When the second sliding plate 822 is moved to the position of the cushioning packaging bag B, the sliding rods 824 in the same group are moved closer to each other so that the pressure rods 825 on the sliding rods 824 move closer to each other, thereby pressing or clamping one side b2 of the cushioning packaging bag B by the pressure rods 825, and controlling the second sliding plate 822 to move to the packaging position 20 during the pressing or clamping process.

[0137] Implementation Method Two:

[0138] As shown in Figures 15 and 16, the conveying module 82 includes a second module 82b and a first module 82a. The first module 82a in this second embodiment is the same as the first module 82a in the first embodiment.

[0139] The second module 82b is disposed between the labeling position 90 and the bag opening position 40, and the first module 82a is disposed between the bag opening position 40 and the packaging position 20; the second module 82b transports the cushioning packaging bag B from the labeling position 90 to the bag opening position 20; the first module 82a is used to transport the cushioning packaging bag B released from the bag opening position 40 and transport the cushioning packaging bag B to the packaging position 20.

[0140] The second module 82b extends relative to the labeling module 90a to the bag opening position 40, and is used to clamp or absorb the bag opening b2 of the cushioning packaging bag B, and to move the cushioning packaging bag B on the support plate 801 to the bag opening position 40 during the clamping or absorption process.

[0141] As shown in Figure 16, the second module 82b includes: a lead screw 826, a fourth sliding plate 827, and a second adsorption structure 828.

[0142] The lead screw 826 is disposed on the machine base A along the conveying direction; the fourth sliding plate 827 is sleeved on the lead screw 826 and slides or stops as the lead screw 826 rotates; the second adsorption structure 828 is positioned on the fourth sliding plate 827, and the second adsorption structure 828 includes a second suction cup 8281, which is disposed toward the cushioning packaging bag B and is used to adsorb the bag opening b2 of the cushioning packaging bag B.

[0143] Wherein, after the second adsorption structure 828 adsorbs the cushion packaging bag B, it moves with the fourth sliding plate 827 under the control of the lead screw 826, so as to realize the cushion packaging bag B being transported from the labeling position 90 to the opening position 40 on the support plate 801.

[0144] In this invention, the second adsorption structure 828 includes two sets of second suction cups 8281, each set of second suction cups 8281 having two; the two sets of second suction cups 8281 are respectively disposed on the upper and lower sides of the cushioning packaging bag B; one set of second suction cups 8281 is used to adsorb the upper surface of the bag opening b2, and the other set of second suction cups 8281 is used to adsorb the lower surface of the bag opening b2.

[0145] When the second suction cup 8281 adsorbs the lower surface of the bag opening b2, the cushioning packaging bag B moves to the opening position 40 along with the fourth sliding plate 827.

[0146] When the second suction cup 8281 adheres to the lower surface of the bag opening b2 and the upper surface of the bag opening b2, the bag opening b2 of the cushioning packaging bag B located at the bag opening position 40 is opened.

[0147] In this invention, when the telescopic member 410 extends into the bag opening b2 and pushes the cushioning sheet b1, the second adsorption structure 828 can open the bag opening b2, facilitating the extension of the telescopic member 410.

[0148] When the device of this invention is in operation: First, cushioning packaging bags are placed in the storage bag bins, and the sizes of the cushioning packaging bags are not exactly the same; then, the device is powered on and turned on; during operation, the feeding belt and the discharging belt are in a continuous conveying process; the gripping module is located at the feeding position, that is, below at least one storage bag bin; the conveying module is located between the labeling position and the packaging position. The vision inspection module detects the items to be packaged on the conveyor belt, obtains the size of the items to be packaged, and then sends the size data to the gripping module. The gripping module automatically selects a packaging bag with a size suitable for the items to be packaged based on the size data, and moves it below the corresponding storage bag bin; the first adsorption structure of the gripping module adsorbs the cushioning packaging bag, causing the cushioning packaging bag to detach from the storage bin and move from below the storage bin to the support plate; then the gripping module moves along the conveying direction, moving the cushioning packaging bag to the labeling position, where the labeling module prints the size, type, and express delivery information of the items to be packaged. After the information corresponding to the information is encoded, the information code is affixed to the cushioning packaging bag; the conveying module moves to the labeling position and uses the second adsorption structure to adsorb the cushioning packaging bag, and moves the cushioning packaging bag to the opening position; the telescopic component of the opening module near the opening position moves towards the opening of the cushioning packaging bag under control and extends into the opening, pushing the cushioning sheet of the cushioning packaging bag, so that the cushioning sheet is pushed or stretched to form the cushioning pad, at which time the cushioning packaging bag has cushioning performance; then the telescopic component retracts from the opening; the conveying module conveys the cushioning packaging bag again to the packaging position. At this time, the item to be packaged, whose size has been identified by the visual inspection module, moves along the feeding belt to the receiving space of the bagging module on one side of the packaging bag. The bagging module pushes the item to be packaged perpendicular to the conveying direction toward the opening of the cushioning packaging bag, loading the item into the cushioning packaging bag. When the item is loaded, the conveying module presses against the two vertical sides of the cushioning packaging bag to prevent it from shifting. After the item is loaded into the cushioning packaging bag, the telescopic rod of the sealing module presses against the bag opening; while the conveying module continues to convey the cushioning packaging bag toward the discharge belt, during which the telescopic rod closes the bag opening; when the conveying module moves to a position where the cushioning packaging bag contacts the discharge belt, the conveying module releases the cushioning packaging bag, and the cushioning packaging bag is output from the discharge belt for packaging or express delivery.

[0149] In this process, after the conveying module acquires the cushioning packaging bag, the gripping module returns to the loading position and grips another cushioning packaging bag of the appropriate size according to the detection structure of the vision inspection module. After releasing the cushioning packaging bag, the conveying module moves towards the labeling position again. When the gripping module picks up the next cushioning packaging bag, moves to the labeling position, and affixes the information code, the conveying module moves back to the labeling position to continue conveying the next cushioning packaging bag. The gripping module and the conveying module repeat the above working process, thereby realizing the automated packaging of the items to be packaged.

[0150] The telescopic component of the bag-opening module and the vertical plate of the bag-filling module adjust their pushing distance toward the cushioning packaging bag according to the size detected by the vision detection module. That is, when the size of the cushioning packaging bag is large, the telescopic component extends deeper into the bag opening, and the vertical plate pushes the item to be packaged deeper. This allows the cushioning sheet to be pushed or stretched to the maximum extent to create a cushioning pad with greater cushioning performance, and also allows all the items to be packaged to be placed into the cushioning packaging bag. The entire process can be automated without human intervention.

[0151] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
