Description

Technical Field

[0001] The present invention relates to the field of packaging technology, and in particular to a bag plugging device and a ton bag plugging method. Background Art

[0002] Ton bags, also known as bulk bags, space bags, and mother-and-child bags, are flexible transport packaging containers that offer moisture-proof, dust-proof, radiation-resistant, and secure properties. They are primarily used for transporting granular or powdered materials. They consist of an inner bag and an outer bag. During packaging, the inner bag, which extends beyond the outer bag, is manually inserted into the outer bag. This approach is labor-intensive and inefficient.

[0003] Therefore, it is necessary to provide a new bag plugging device and a ton bag plugging method to solve the above technical problems. Summary of the Invention

[0004] The main purpose of the present invention is to provide a bag plugging device and a bag plugging method for ton bags, aiming to solve the technical problems of high labor intensity and low work efficiency of workers in the existing technology when the bag plugging work is completed manually.

[0005] To achieve the above-mentioned purpose, the present invention provides a bag plugging device, comprising:

[0006] A frame, wherein the frame is formed with an accommodating space;

[0007] an unfolding mechanism, the unfolding mechanism comprising a plurality of clamping assemblies for clamping the bag edge of the outer bag, each of the clamping assemblies being movable along a first direction of the frame in a direction away from the accommodating space to unfold the bag opening of the outer bag;

[0008] The bag plugging mechanism includes a pushing member, which can move along the second direction of the frame and be inserted into the accommodating space to plug the portion of the inner bag extending out of the outer bag into the outer bag.

[0009] In one embodiment, the bag stuffing mechanism further includes a first driving unit, which is disposed on the frame and connected to the pushing member, and the first driving unit can drive the pushing member to move along the second direction of the frame.

[0010] In one embodiment, the first driving unit is slidably disposed on the frame along the second direction of the frame, and the frame is provided with a second driving unit; the second driving unit is connected to the first driving unit and can drive the first driving unit to slide along the second direction of the frame, and the speed at which the second driving unit drives the first driving unit to slide is less than the speed at which the first driving unit drives the pushing member to move.

[0011] In one embodiment, the pushing member includes a pushing block, a driving module arranged on the pushing block, and two clamping units cross-arranged on the driving module. The driving module can drive the two clamping units to rotate so that the two clamping units move toward or away from each other.

[0012] In one embodiment, there are two driving modules, the two driving modules are spaced apart from each other on the pushing block, and each driving module is provided with two clamping units.

[0013] In one embodiment, the pushing member includes a pushing block, and the pushing block is provided with a receiving groove for receiving the portion of the inner bag extending out of the outer bag.

[0014] In one embodiment, the unfolding mechanism also includes two driving components, the driving component including a slide rail provided on the frame, a slider provided on the slide rail and sliding along a first direction of the frame, a first driving body provided on the slide rail and connected to the slider, and a second driving body provided on the slider. The number of the clamping components is two, and the clamping components are connected to the second driving bodies in a one-to-one correspondence. The first driving body can drive the slider to slide along the first direction of the frame toward or away from the accommodating space, and the second driving body can drive the clamping component to move along the second direction of the frame toward or away from the accommodating space.

[0015] In one embodiment, the clamping assembly includes a mounting frame, a first clamping member, and a second clamping member, wherein the first clamping member and the second clamping member are spaced apart from each other on the mounting frame.

[0016] In one embodiment, the first clamping member and the second clamping member each include a driving cylinder and two clamping rods cross-arranged on the driving cylinder; the driving cylinder can drive the two clamping rods to rotate so that the two clamping rods move toward or away from each other, and a clamping block is provided on the side of the two clamping rods facing each other at one end away from the driving cylinder.

[0017] In addition, the present invention also provides a method for plugging ton bags, which is applied to the bag plugging device described above. The method for plugging ton bags comprises the following steps:

[0018] The driving assembly of the unfolding mechanism is controlled to drive the clamping assembly to move along the first direction of the frame toward the accommodating space to the accommodating space, and to control the clamping assembly to clamp the bag edge of the outer bag;

[0019] The driving assembly of the unfolding mechanism is controlled to drive the clamping assembly to move along the first direction of the frame toward a direction away from the accommodating space, so as to unfold the bag opening of the outer bag;

[0020] The first driving unit of the bag plugging mechanism is controlled to drive the pushing member to move along the second direction of the frame, so that the pushing member is inserted into the accommodating space to plug the portion of the inner bag extending out of the outer bag into the outer bag.

[0021] The technical solution of the present invention is to provide a clamping assembly that can move along a first direction of the frame away from the accommodating space, thereby expanding the outer bag of a ton bag placed in the accommodating space; and to provide a pushing member that can move along a second direction of the frame, so that the pushing member can be inserted into the accommodating space, thereby inserting the portion of the inner bag that extends out of the outer bag into the outer bag, thereby completing the ton bag stuffing work. Using this bag stuffing device instead of manually completing the ton bag stuffing work can reduce the labor intensity of workers and improve work efficiency. In this embodiment, each clamping assembly can move along the first direction of the frame away from the accommodating space to expand the bag opening of the outer bag, so that the bag stuffing mechanism can insert the portion of the inner bag that extends out of the outer bag into the outer bag; the pushing member can move along the second direction of the frame and be inserted into the accommodating space to insert the portion of the inner bag that extends out of the outer bag into the outer bag. After the ton bag is transferred to the storage space, the clamping assembly grips the edge of the outer bag and moves along the first direction of the frame, away from the storage space, to unfold the outer bag opening. The bag-stuffing device is then inserted into the storage space and inserts the portion of the inner bag that extends beyond the outer bag, completing the ton bag stuffing process. This bag-stuffing device replaces manual labor for ton bag stuffing, reducing worker intensity and improving work efficiency. It has applications in ton bag packaging, material packaging, and other technical fields. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0036] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that meet both A and B.

[0037] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0038] Ton bags, also known as bulk bags, space bags, and mother-and-child bags, consist of an inner bag and an outer bag. The inner bag is used to hold the material, and the outer bag is used to protect the inner bag and prevent it from being scratched. When packaging existing ton bags, the outer bag must first be placed over the inner bag, and then the material is poured into the inner bag and the inner bag is sealed. After that, the sealed inner bag is manually stuffed completely into the outer bag, and finally the bag opening of the outer bag is tied to complete the packaging of the ton bag. However, in actual work, the production volume of ton bags is huge, and workers need to completely stuff the inner bag of each ton bag into the outer bag. This increases the workers' labor intensity. As the working hours increase, the time it takes for workers to completely stuff the inner bag into the outer bag will increase, which will affect production efficiency.

[0039] The present invention provides a bag plugging device and a bag plugging method for ton bags, aiming to solve the technical problems of high labor intensity and low work efficiency of workers in the prior art when bag plugging is done manually.

[0040] See also Figures 1 to 3 In one embodiment of the present invention, the bag stuffing device includes a frame 100, an unfolding mechanism 200, and a bag stuffing mechanism 300. The frame 100 is formed with a accommodating space 110. The unfolding mechanism 200 includes a plurality of clamping components 210 for clamping the bag edge of the outer bag. Each clamping component 210 can move along a first direction of the frame 100 in a direction away from the accommodating space 110 to unfold the bag opening of the outer bag; the bag stuffing mechanism 300 includes a pushing member 310. The pushing member 310 can move along a second direction of the frame 100 and be inserted into the accommodating space 110 to stuff the portion of the inner bag extending out of the outer bag into the outer bag. The first direction is Figure 3 The second direction is the direction indicated by X in Figure 1 and Figure 3In the direction indicated by Z, in a specific embodiment, the first direction may be a horizontal direction, and the second direction may be a vertical direction.

[0041] The technical solution of the present invention is to provide a clamping assembly 210 that can move along a first direction of the frame 100 in a direction away from the accommodating space 110, thereby being able to unfold the outer bag of a ton bag placed in the accommodating space 110; and to provide a pushing member 310 that can move along a second direction of the frame 100, so that the pushing member 310 can be inserted into the accommodating space 110, and the portion of the inner bag extending out of the outer bag can be stuffed into the outer bag, thereby completing the stuffing operation of the ton bag. In this embodiment, each clamping assembly 210 can move along the first direction of the frame 100 in a direction away from the accommodating space 110 to unfold the bag opening of the outer bag, so that the stuffing mechanism 300 can stuff the portion of the inner bag extending out of the outer bag into the outer bag; the pushing member 310 can move along the second direction of the frame 100 and be inserted into the accommodating space 110, so as to stuff the portion of the inner bag extending out of the outer bag into the outer bag. After the ton bag is transferred to the storage space 110, the clamping assembly 210 grips the edge of the outer bag and moves along the first direction of the frame 100, away from the storage space 110, to expand the outer bag opening. The bag-stuffing device is then inserted into the storage space 110 and inserts the portion of the inner bag that extends beyond the outer bag, completing the ton bag stuffing process. This bag-stuffing device can replace manual labor in the ton bag stuffing process, reducing worker workload and improving work efficiency. This bag-stuffing device has applications in the packaging of ton bags, material packaging, and other technical fields.

[0042] It should be noted that, in addition to being used for the stuffing of ton bags, the bag stuffing device can also be used for the compacting of materials in single-layer bags; for example: after the material is loaded into the single-layer bag, the material needs to be compacted so that the material can continue to be loaded into the single-layer bag, thereby increasing the amount of material that the single-layer bag can accommodate, and thus improving the material transfer efficiency. The compacting of the material can be completed by the bag stuffing device, and in actual use, the pushing member 310 can be replaced with a pressing block required to compact the material according to actual needs.

[0043] See also Figure 2 In one embodiment of the present invention, the bag inserting mechanism 300 further includes a first driving unit 320. The first driving unit 320 is disposed on the frame 100 and connected to the pusher 310. The first driving unit 320 can drive the pusher 310 to move along the second direction of the frame 100. When inserting the portion of the inner bag extending out of the outer bag into the outer bag, the first driving unit 320 drives the pusher 310 to move along the second direction of the frame 100 and insert the pusher 310 into the accommodating space 110, thereby inserting the portion of the inner bag extending out of the outer bag into the outer bag.

[0044] In one embodiment of the present invention, the first drive unit 320 is slidably disposed on the frame 100 along the second direction of the frame 100, and the frame 100 is provided with a second drive unit 120. The second drive unit 120 is connected to the first drive unit 320 and can drive the first drive unit 320 to slide along the second direction of the frame 100. The speed at which the second drive unit 120 drives the first drive unit 320 to slide is slower than the speed at which the first drive unit 320 drives the pusher 310 to move. When inserting the portion of the inner bag extending from the outer bag into the outer bag, the second drive unit 120 first drives the first drive unit 320 to descend, thereby driving the pusher 310 to descend to the opening of the outer bag. Subsequently, the first drive unit 320 drives the pusher 310 to descend, causing the pusher 310 to be inserted into the accommodating space 110, thereby inserting the portion of the inner bag extending from the outer bag into the outer bag. The speed at which the second drive unit 120 drives the first drive unit 320 to slide is slower than the speed at which the first drive unit 320 drives the pusher 310 to move. That is, the second drive unit 120 drives the pusher 310 at a slower speed, which enables the pusher 310 to accurately stop at the opening of the outer bag, while the first drive unit 320 drives the pusher 310 at a faster speed, which enables the first drive unit 320 to drive the pusher 310 to move, thereby quickly inserting the inner bag into the outer bag and quickly withdrawing the pusher 310 from the outer bag to facilitate the subsequent bundling of the outer bag. At the same time, to prevent the inner bag from popping out of the outer bag after being completely inserted into the outer bag, the first drive unit 320 can be controlled to drive the pusher 310 to repeatedly rise and fall to compact the inner bag and ensure that the inner bag does not pop out of the outer bag. In a specific embodiment, the first drive unit 320 can be a pneumatic cylinder and the second drive unit 120 can be an electric cylinder.

[0045] See also Figure 2In an embodiment of the present application, the pushing member 310 comprises a pushing block 311, a driving module 312 arranged on the pushing block 311, and two clamping units 313 arranged crosswise on the driving module 312, and the driving module 312 can drive the two clamping units 313 to rotate so as to move the two clamping units 313 towards each other or away from each other. After the second driving unit 120 drives the pushing member 310 to descend to the bag opening of the outer bag, the driving module 312 drives the two clamping units 313 to rotate so as to move the two clamping units 313 towards each other, and clamps the part of the inner bag extending out of the outer bag, thereby avoiding the part of the inner bag extending out of the outer bag from being separated from the pushing member 310 in the process of being inserted into the outer bag. In a specific embodiment, the driving module 312 can be a jaw cylinder, a finger cylinder, or the like; and one of the two clamping units 313 can be arranged fixedly, and the driving module 312 drives the other clamping unit 313 to rotate, so as to move the two clamping units 313 towards each other or away from each other. In addition to the two rotating clamping units 313, the part of the inner bag extending out of the outer bag can also be clamped by two clamping units 313 capable of moving towards each other or away from each other, and according to actual needs, the two clamping units 313 can be arranged slidingly, or one of the two clamping units 313 can be arranged slidingly, and the other clamping unit 313 can be arranged fixedly.

[0046] In an embodiment of the present application, the number of the driving modules 312 is two, the two driving modules 312 are arranged spaced apart on the pushing block 311, and each of the driving modules 312 is arranged with two clamping units 313. That is, by simultaneously driving the four clamping units 313 to rotate by the two driving units, two different positions of the part of the inner bag extending out of the outer bag can be clamped simultaneously, so as to avoid the inner bag from slipping off the pushing block 311. In a specific embodiment, the number of the driving modules 312 can also be three or four, and each of the driving modules 312 is arranged with two clamping units 313.

[0047] In an embodiment of the present application, the pushing member 310 comprises a pushing block 311, and a receiving groove for accommodating the part of the inner bag extending out of the outer bag is arranged on the pushing block 311. Specifically, the pushing block 311 is arranged with a receiving groove, and the receiving groove is used to accommodate the part of the inner bag extending out of the outer bag; when the first driving unit 320 drives the pushing block 311 to move along the second direction of the rack 100, and inserts the part of the inner bag extending out of the outer bag into the outer bag, the inner bag is arranged in the receiving groove. By arranging the receiving groove on the pushing block 311 to limit the position of the part of the inner bag extending out of the outer bag, the part of the inner bag extending out of the outer bag can be prevented from slipping off the pushing block 311.

[0048] Please refer to Figures 3 to 5In one embodiment of the present invention, the unfolding mechanism 200 further includes two driving assemblies 220, the driving assembly 220 including a slide rail 221 provided on the frame 100, a slider 222 provided on the slide rail 221 and sliding along a first direction of the frame 100, a first driving body 223 provided on the slide rail 221 and connected to the slider 222, and a second driving body 224 provided on the slider 222. There are two clamping assemblies 210, and the clamping assemblies 210 are connected to the second driving bodies 224 in a one-to-one correspondence. The first driving body 223 can drive the slider 222 to slide along the first direction of the frame 100 toward or away from the accommodating space 110, and the second driving body 224 can drive the clamping assembly 210 to move along the second direction of the frame 100 toward or away from the accommodating space 110.

[0049] After the ton bag is transferred to the accommodating space 110, the first driving body 223 drives the slider 222 to slide along the first direction of the frame 100 toward the accommodating space 110, thereby driving the clamping assembly 210 to slide toward the accommodating space 110. Then, the second driving body 224 drives the clamping assembly 210 to descend. After the clamping assembly 210 clamps the bag edge of the outer bag, the first driving body 223 again drives the slider 222 to slide along the first direction of the frame 100, causing the slider 222 to move away from the accommodating space 110, driving the clamping assembly 210 to move away from the accommodating space 110. Through the combined action of the clamping assemblies 210 of the two driving assemblies 220, the bag opening of the outer bag can be opened. The opening mechanism 200 drives the clamping assembly 210 to move along two different directions of the frame 100 via the first driving body 223 and the second driving body 224 to open the bag opening of the outer bag. It has the advantage of a simple structure, which can simplify the structure of the packaging equipment and reduce the difficulty of manufacturing. In a specific embodiment, the first driving body 223 and the second driving body 224 can be an electric cylinder, a pneumatic cylinder, an oil cylinder, etc. In a more specific embodiment, the second driving body 224 is arranged on the slider 222 so as to be lifted and lowered, and the slider 222 is provided with an electric cylinder capable of driving the second driving body 224 to be lifted and lowered. The second driving body 224 is a pneumatic cylinder, wherein the operating speed of the electric cylinder is lower than the operating speed of the pneumatic cylinder. Therefore, when driving the clamping assembly 210 to descend, the electric cylinder can first drive the second driving body 224 to descend to a suitable position to ensure the accurate position of the clamping assembly 210. Then, the second driving body 224 drives the clamping assembly 210 to descend, so that the clamping assembly 210 can be quickly lowered to the clamping position, reducing the time for the clamping assembly 210 to move to the clamping position and improving work efficiency.

[0050] See also Figure 4 and Figure 5In one embodiment of the present invention, the clamping assembly 210 includes a mounting frame 211, a first clamping member 212, and a second clamping member 213. The first clamping member 212 and the second clamping member 213 are spaced apart from the mounting frame 211. The first clamping member 212 and the second clamping member 213 are both used to clamp the edge of the outer bag. The two driving assemblies 220 are each provided with two clamping members. When the unfolding mechanism 200 unfolds the bag opening of the outer bag, the four clamping members can cooperate with each other to unfold the bag opening of the outer bag into a square shape. This can increase the size of the bag opening after unfolding, making it easier for the bag stuffing mechanism 300 to stuff the portion of the inner bag that extends out of the outer bag into the outer bag. When assembling the clamping assembly 210, the spacing between the two clamping members can be set to different sizes to meet actual usage requirements. In addition, the number of drive components 220 can be three, four, etc., and the number of clamping parts of the clamping component 210 can be three, four, etc., and according to actual usage requirements, multiple clamping parts can be arranged to be distributed in an arc shape so that the bag opening of the outer bag presents different shapes after the outer bag is unfolded; and the number of drive components 220 can also be one, which only requires setting corresponding connecting rod structures and linkage structures between the drive component 220 and each clamping component 210 so that each clamping component 210 can move synchronously.

[0051] In one embodiment of the present invention, the first clamping member 212 and the second clamping member 213 each include a drive cylinder 2121 and two clamping rods 2122 cross-connected to the drive cylinder 2121. The drive cylinder 2121 can drive the two clamping rods 2122 to rotate so that the two clamping rods 2122 move toward or away from each other. Specifically, the drive cylinder 2121 can drive the two clamping rods 2122 to rotate so that the two clamping rods 2122 move toward each other, that is, reduce the angle between the two clamping rods 2122, and thereby clamp the bag edge of the outer bag. The drive cylinder 2121 can also drive the two clamping rods 2122 to rotate so that the two clamping rods 2122 move away from each other, that is, increase the angle between the two clamping rods 2122, and thereby release the bag edge of the outer bag. By driving two clamping rods 2122 to rotate through a single drive cylinder 2121 to clamp or release the edge of the outer bag, the structure can be simplified, the difficulty of manufacturing the bag-stuffing device can be reduced, and the number of drive structures used can be reduced, thereby lowering production costs. In a specific embodiment, the drive cylinder 2121 can be a clamping claw cylinder or a finger cylinder. In addition, one of the clamping rods 2122 can be configured as a fixed installation, and the drive cylinder 2121 can drive the other clamping rod 2122 to rotate, thereby causing the two clamping rods 2122 to move toward or away from each other. In addition to using two cross-arranged clamping rods 2122 to clamp the edge of the outer bag, two clamping blocks 2123 that can move toward or away from each other can also be used for clamping. Depending on actual needs, both clamping blocks 2123 can be configured to slide, or one clamping block 2123 can be configured to slide and the other clamping block 2123 can be configured to be fixed.

[0052] The two clamping rods 2122 are each provided with a clamping block 2123 on the opposite side of their ends away from the drive cylinder 2121. The edge of the outer bag can be clamped between the two clamping blocks 2123. When the clamping assembly 210 clamps the edge of the outer bag, the two clamping rods 2122, moving toward each other, clamp the edge of the outer bag via the clamping blocks 2123. At this time, the contact between the two clamping blocks 2123 and the outer bag is linear, which prevents the edge of the outer bag from becoming loose after being clamped by the clamping assembly 210, thereby ensuring that the outer bag opening can be normally unfolded under the action of the unfolding mechanism 200. In a specific embodiment, the clamping block 2123 can be hook-shaped, and in order to prevent the edge of the outer bag from slipping between the two clamping blocks 2123 after the clamping block 2123 clamps the edge of the outer bag, a corresponding wear-resistant layer for increasing friction can be provided on the clamping block 2123, such as: coating the clamping block 2123 with rubber material.

[0053] See also Figure 6 andFigure 7 The present invention also provides a packaging device comprising the aforementioned bag-stuffing device, a bag-feeding device 400, and a strapping device 500. The bag-feeding device 400 is used to transport ton bags to the storage space 110 of the rack 100; the bag-stuffing device is used to insert the portion of the inner bag that extends beyond the outer bag into the outer bag; and the strapping device 500 is used to tighten and strap the outer bag. During packaging, the bag-stuffing device 400 first transports the ton bag to the storage space 110, then the bag-stuffing device inserts the portion of the inner bag that extends beyond the outer bag into the outer bag. Finally, the strapping device 500 tightens and straps the outer bag, completing the packaging of the ton bag.
