Technical Field

[0001] This application relates to the field of packaging and transportation devices, and in particular to a packaging unpacking and transportation mechanism. Background Technology

[0002] During product manufacturing, small packages need to be packed into larger packages for easier transportation and sales. For example, in the production of cigarette cartons, small boxes containing several cigarettes need to be packed into long, rectangular cartons. Currently, the packaging method for cigarette cartons is usually manual, involving operators placing the cartons on a conveyor belt and opening the outer lid. The cartons are then transported along the conveyor belt to subsequent workstations, where operators pack the smaller boxes into the larger cartons. This method has several drawbacks. First, manually opening the cartons requires significant manpower. Second, manually placed cartons are prone to tilting on the conveyor belt, affecting transportation and inspection. Tilted cartons require straightening, making the process cumbersome and inefficient. Utility Model Content

[0011] The beneficial effects of this application are:

[0012] 1. A packaging box opening and transport mechanism of this application includes a feeding structure, a transport structure, a box opening structure, and a conveyor alignment structure. The feeding structure feeds the carton to the transport structure. After the carton is fed into the transport structure, it is positioned by the positioning component. At this time, the box opening structure is activated. The box opening arm rotates, causing the box opening suction cup to approach the carton and adsorb the outer cover of the carton. After the outer cover is adsorbed, the box opening arm rotates again, causing the box opening suction cup to move away from the carton, thus opening the outer cover. The carton with the outer cover opened is transported by the conveyor component to the conveyor alignment structure. The conveyor alignment structure uses a lifting alignment component to lift and position the carton, so that the carton is in the correct position for transport to subsequent processes. The entire process does not require manual operation, which can effectively reduce labor consumption and ensure the efficiency of box opening and packaging.

[0013] 2. A packaging, opening, and transporting mechanism of this application includes a lifting and alignment component in addition to the positioning component for positioning the carton. The lifting plate and alignment column work together with the positioning component for alignment. When the positioning component transports the carton to the lifting and alignment component, the lifting plate rises and falls under the drive of the alignment drive component, and the alignment column rises into the positioning hole of the positioning component, allowing the positioning component to fine-tune and further align itself, thus ensuring the positional accuracy of the carton for subsequent processes.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0027] Reference Figure 1 as well as Figure 2This application provides a packaging box opening and transportation mechanism, including a base 1 and a feeding structure 2 disposed on the base 1, as well as a transportation structure 3, a box opening structure 4, and a conveying alignment structure 5 disposed on the base 1. The feeding structure 2 feeds the carton to the transportation structure 3. After the carton is sent into the transportation structure 3, it is positioned by the positioning component 32. At this time, the box opening structure 4 operates to open the outer cover. The carton with the outer cover opened is transported by the conveying component 31 to the conveying alignment structure 5. The conveying alignment structure 5 lifts and positions the carton so that the carton is in the correct position for transportation to subsequent processes. The entire process does not require manual operation, which can effectively reduce labor consumption and ensure the efficiency of opening and packaging.

[0028] Specifically, the base 1 supports the various structures. The feeding structure 2 includes a feeding assembly and a pushing assembly (not shown in the figure) disposed on the base 1. The feeding assembly includes several feeding rollers and a feeding belt rotatably connected to the base 1. The feeding rollers are horizontally arranged, and the feeding belt covers the feeding rollers. The feeding rollers are driven by a motor to rotate. The feeding belt has baffles on both sides. Stacked packaging boxes are placed on the feeding belt. Driven by the feeding rollers, the stacked packaging boxes are transported along the feeding belt to the transport structure 3. The pushing assembly includes a pushing cylinder and a pushing block. Driven by the pushing cylinder, the pushing block pushes the packaging boxes out of the feeding belt and into the positioning conveyor structure.

[0029] Reference Figure 3 , Figure 4 as well as Figure 5 The transport structure 3 includes a conveying assembly 31, a plurality of positioning components 32 disposed on the conveying assembly 31, and a positioning drive assembly 33 for opening the positioning components 32. Specifically, to accommodate the installation of the conveying assembly 31, the base 1 has a conveying groove along its length. The conveying assembly 31 includes a plurality of conveying rollers 311 rotatably connected to the base 1 and a conveyor belt 312. The plurality of conveying rollers 311 are located in the conveying groove and are arranged along the length of the conveying groove. The conveyor belt 312 covers the plurality of conveying rollers 311. The conveying rollers 311 are driven by a motor, and under the drive of the conveying rollers 311, the conveyor belt 312 drives the plurality of positioning components 32 to move.

[0030] Several positioning components 32 are evenly arranged along the length of the conveyor belt 312. Each positioning component 32 includes a positioning fixture 321 for clamping and fixing the strip box, and a positioning drive component 33 faces the positioning component 32. Taking a single positioning fixture 321 as an example, a single positioning fixture 321 includes two fixture seats 3211, and there is a cavity between the two fixture seats 3211 for accommodating the strip box. It is understood that a single positioning fixture 321 has a cavity, and a single positioning fixture 321 can also cooperate with adjacent positioning fixtures 321 to form a cavity.

[0031] On opposite sides of adjacent fixture seats 3211, there are first limiting seats 32111 and second limiting seats 32112 to prevent the strip box from accidentally entering. The first limiting seat 32111 is fixed in position, and a first limiting block 3212 is slidably connected to the outside of the first limiting seat 32111. The second limiting seat 32112 is slidably connected to the fixture seat 3211 and is located at the four corners of the fixture seat 3211. A second limiting block 3213 is slidably connected to the inside of the second limiting seat 32112. The first limiting block 3212 and the second limiting block 3213 are slidably connected to the corresponding limiting seats by springs. The springs apply a force to the first limiting block 3212 and the second limiting block 3213 toward the other side. In the initial state, the first limiting block 3212 and the second limiting block 3213 extend under the action of the spring, blocking the packaging box from entering and preventing the packaging box from being pushed in by mistake. Subsequently, under the drive of the positioning drive component 33, the first limiting block 3212 and the second limiting block 3213 open to allow the packaging box to be sent in.

[0032] After the packaging box is fed in, the positioning fixture 321 clamps the packaging box under the drive of the positioning drive component 33, that is, the first limiting block 3212 and the second limiting block 3213 open, and the packaging box is fed between the two positioning fixtures 321. Specifically, the first limiting block 3212 is clamped at the middle position in the width direction of the packaging box, and the first limiting block 3212 is used to position and fix the overall position of the packaging box. The second limiting blocks 3213 are clamped on both sides in the width direction of the packaging box, one of which is the rotating side of the outer cover, so that one of the second limiting blocks 3213 can be used to restrict the rotation of the outer cover of the packaging box, so as to prevent the outer cover from being accidentally opened and affecting subsequent processes. It should be noted that the number and position of the limiting blocks can be adjusted according to actual needs.

[0033] The positioning drive assembly 33 includes a first positioning drive member 331 and a second positioning drive member 332. The first positioning drive member 331 is a cylinder. The first positioning drive member 331 is provided with a wedge 3311 facing the first limiting block 3212. The first limiting block 3212 has a first groove. The wedge 3311 contacts or disengages from the first groove. Under the drive of the cylinder, the wedge 3311 extends out and contacts the first groove. Under the drive of the wedge 3311, the two first limiting members move away from each other to open. Similarly, the second positioning drive 332 is a cylinder. The second positioning drive 332 is provided with a top block 3321 facing the second limiting block 3213. The second limiting block 3213 has a second groove. The top block 3321 contacts or disengages from the second groove. Under the drive of the cylinder, the top block 3321 extends out and contacts the second groove. Under the drive of the top block 3321, the two second limiting blocks 3213 and the corresponding second limiting seats 32112 move away from each other to open and release the limiting of the outer cover.

[0034] Reference Figure 2 , Figure 3 as well as Figure 6 After the packaging box is fed in, the first positioning drive 331 moves away from the corresponding groove, causing the first limiting block 3212 to clamp onto both sides of the packaging box; the second positioning drive 332 remains open, allowing the box opening structure 4 to open the outer cover of the packaging box. The box opening structure 4 opens the packaging box. Specifically, the box opening structure 4 includes a box opening support 41 disposed on the base 1, a box opening assembly 42, and a box opening drive 43 for driving the box opening assembly 42. The box opening support 41 is fixedly installed on the base 1 and is located on one side of the feeding structure 2. The box-opening assembly 42 includes a box-opening rotating arm 421 rotatably connected to a box-opening support base 41 and several box-opening suction cups 422 disposed on the box-opening rotating arm 421. The several box-opening suction cups 422 face the positioning assembly 32. In order to adapt to the installation of the box-opening rotating arm 421, the box-opening support base 41 has box-opening guide rails 411 on both sides. The box-opening guide rails 411 are arc-shaped and face the feeding structure 2. The box-opening guide rails 411 have guide rail grooves along their extension direction. Correspondingly, the box-opening rotating arm 421 is located between the two box-opening guide rails 411 and passes through the box-opening support base 41. One end of the box-opening rotating arm 421 has a swing arm 4211 slidably connected to the guide rail groove. The several box-opening suction cups 422 are disposed on the swing arm 4211. The other end of the box-opening rotating arm 421 has a transmission arm 4212. The swing arm 4211 and the transmission arm 4212 are hinged. The other end of the transmission arm 4212 has a rotating shaft, which is connected to the box opening drive component 43. The box opening drive component 43 is a motor. The rotating shaft is connected to the box opening drive component 43 through a coupling, so that the box opening assembly 42 forms a centerless box opening structure 4.

[0035] When the box-opening drive unit 43 is activated, it drives the transmission arm 4212 to rotate via the drive shaft. The rotating transmission arm 4212 drives the swing arm 4211 to slide along the box-opening guide rail 411, so that the swing arm 4211 carries the box-opening suction cup 422 along a preset path to approach the packaging box. After the box-opening suction cup 422 contacts the packaging box, it adheres to the outer cover of the packaging box. The box-opening drive unit 43 drives the swing arm 4211 to slide in the opposite direction, and the box-opening suction cup 422 drives the outer cover to open. After the outer cover is opened, the box-opening suction cup 422 is released from adsorption. At the same time, the second positioning drive unit 332 releases the limit on the second limiting block 3213. Since the outer cover is now open, the second limiting block 3213 located on one side of the outer cover will press against one side of the outer cover. The second limiting block 3213 located on the other side of the outer cover will cooperate with the first limiting block 3212 to position the packaging box. Subsequently, the conveying component 31 and the positioning component 32 move to drive the packaging box into the conveying alignment structure 5.

[0036] Reference Figure 7 as well as Figure 8Furthermore, in this embodiment, to prevent the outer cover of the packaging box from closing at a subsequent workstation, the base 1 is provided with several baffles 11 along the conveying groove, and the baffles 11 are located at the position of the conveying alignment structure 5. When the positioning component 32 moves the packaging box with the outer cover open to this position, the baffles 11 will be located between the outer cover and the packaging box, thereby preventing the outer cover from closing.

[0037] The conveying alignment structure 5 includes a fixed base 51 disposed on the base 1, a lifting alignment component 52 slidably connected to the fixed base 51, and an alignment drive component 53 for driving the lifting alignment component 52. The lifting alignment component 52 faces the positioning component 32. Specifically, the fixed base 51 is located below the base 1 and has a plurality of fixing posts 511. The fixing posts 511 are fixedly connected to the base 1 so that the position of the fixed base 51 is fixed.

[0038] The lifting and alignment assembly 52 includes a lifting plate 521 slidably connected to the fixed base 51. To accommodate the installation of the lifting plate 521, the fixed base 51 is provided with several guide slide seats, and the lifting plate 521 is provided with several guide slide columns 5211. The guide slide columns 5211 are slidably connected to the guide slide seats, and a return spring is provided between the guide slide columns 5211 and the guide slide seats. Driven by the alignment drive assembly 53, the lifting plate 521 rises and falls relative to the fixed base 51 under the guidance of the guide slide columns 5211. When the lifting plate 521 is lifted, it aligns with the positioning assembly 32. After alignment, the lifting plate 521 quickly returns to its original position under the action of the return spring to prepare for the next lifting operation.

[0039] To align the positioning component 32, the lifting plate 521 is provided with several alignment posts 522 passing through the base 1. The alignment posts 522 are located at the four corners of the lifting plate 521. The positioning component 32 has alignment holes 321121 for engaging with the alignment posts 522. The alignment posts 522 are either inserted into or disengaged from the alignment holes 321121. In this embodiment, the alignment holes 321121 are located in the second limiting seats 32112. When the lifting plate 521 is raised, the four alignment posts 522 will respectively pass into the alignment holes 321121 of the four second limiting seats 32112. At this time, the four second limiting seats 32112 will be aligned under the action of the alignment posts 522, thereby driving the packaging box to be aligned and ensuring the alignment accuracy of the packaging box.

[0040] The alignment drive assembly 53 includes an alignment drive motor 531 mounted on the fixed base 51 and an alignment shaft mounted on the alignment drive motor 531. The alignment shaft is provided with a plurality of alignment cams 532, which abut against the lifting plate 521 and the base 1. The alignment drive motor 531 is connected to the alignment shaft via a coupling. When the alignment drive motor 531 is started, it drives the alignment shaft to rotate. The rotating alignment shaft drives the plurality of alignment cams 532 to rotate, thereby driving the lifting plate 521 to move up and down.
