Description

Technical Field

[0001] The present invention belongs to the technical field of wet wipe stacking packaging, and particularly relates to a stacking mechanism for wet wipe production. Background Art

[0002] At present, most of the stacking and conveying equipment supporting the existing wet wipe production lines are single-function fixed structures, only having simple material conveying or simple mechanical stacking functions. The equipment has a low degree of integration and cannot achieve the integrated collaborative operation of wet wipe box conveying, wet wipe package attitude detection, clamping and transfer, orientation adjustment, and in-box regular shaping. The layout of the components of traditional equipment is scattered, the structure is redundant, and there is a lack of an embedded hidden assembly design. During operation, problems such as component movement rubbing and mechanism interference jamming are likely to occur, making it difficult to adapt to the continuous supporting operation conditions of an automated production line. At the same time, most of the existing similar intelligent packaging equipment adopts rigid limit conveying and extensive mechanical stacking modes, lacking a flexible positioning and clamping structure for wet wipe boxes. During the conveying process, the boxes are prone to shift and shake. And there is no special intelligent detection and automatic correction mechanism for the opening orientation of the wet wipe package covers, relying on manual assistance for placement and correction. The degree of automation of the operation is low, the stacking orientation is messy, the arrangement is loose and the consistency is poor, making it difficult to meet the actual production and use requirements of high efficiency, high regularity, and unmanned automatic stacking and boxing of special intelligent packaging equipment in the wet wipe industry.

[0003] Therefore, we propose a stacking mechanism for wet wipe production to solve the above problems. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention forms a stable load-bearing base through a base plate, support rods, and support plates. The conveying components, stacking components, and detection components are arranged in sections and assembled in a coordinated manner. The components are compactly and rationally connected, with no redundant structures. Compared with the existing single fixed stacking structure, this invention integrates material conveying, posture detection, clamping and transfer, directional stacking, and internal shaping into one unit. The whole machine has a high degree of integration and reasonable space occupation, making it suitable for back-end installation and use in automated wet wipe production lines. At the same time, each functional component adopts an embedded and hidden assembly design. The groove structure accommodates corresponding electric slide rails and electric telescopic rods, effectively avoiding component scraping, interference, and jamming during the movement of the mechanism. The structural stability and assembly adaptability are significantly improved, and it can be compatible with continuous operation conditions of the production line.

[0017] This invention achieves automatic conveying and flexible positioning of wet wipe boxes through a conveying assembly. A first motor, conveyor rollers, and conveyor belt work together to complete the fixed-point transfer of the box. A conveyor shell, fixed airbags, and an air pump provide flexible clamping and fixation of the wet wipe box, preventing displacement and shaking during transport. The stacking assembly, relying on multiple sets of electric slide rails, electric telescopic rods, and motors, forms a multi-dimensional translation, lifting, rotation, and clamping adjustment structure. It can automatically complete wet wipe pack grabbing, cross-station transfer, posture angle correction, and precise box stacking. An independent detection assembly is added, using pressure sensors and various adjustment components to automatically identify the orientation of the wet wipe pack's opening. Packs with abnormal orientations are automatically corrected to ensure all wet wipe packs have the same opening orientation within the box. Finally, a pusher plate compresses and shapes the stacked wet wipe packs, ensuring a tight and neat arrangement within the box. Compared to existing technologies that rely on manual placement or simple, mechanical stacking, this invention features fully automated, interconnected operations that require no human intervention. It ensures high consistency and regularity in stacking, effectively avoiding the problems of misalignment and messy stacking caused by manual placement.

[0018] This invention features a dedicated detection component that utilizes a third electric slide rail, a ninth electric telescopic rod, and a tenth electric telescopic rod in conjunction with a pressure sensor to form a non-contact attitude detection and feedback mechanism. This mechanism can adaptively match the shape and structure of the wet wipe pack for position detection and attitude judgment. The detection and adjustment are flexible and the identification is accurate, providing precise signal support for subsequent automatic orientation and stacking. The entire machine adopts a mechatronics integrated collaborative control mode, with each motor, electric slide rail, and electric telescopic rod starting and stopping sequentially according to the process sequence. There is no invalid idling or redundant action loss, and the process connection is compact and efficient. At the same time, the flexible airbag clamping replaces the traditional rigid limiting structure, avoiding hard compression damage to the wet wipe box and adapting to the stacking operation requirements of different specifications of wet wipe boxes and wet wipe packs.

[0043] The operating principle of the present invention is described as follows:

[0044] In this invention, when it is necessary to automatically stack and store the wet wipe packs produced by the production line into the wet wipe box to complete the intelligent packaging of the finished product, the base plate 1 of the whole machine is first arranged on one side of the end of the wet wipe pack production line, so that the fixing plate 51 is correspondingly set at the discharge end of the production line; the base plate 1, the support rod 2, and the support plate 3 constitute the whole machine bearing frame, which provides a stable installation foundation and working space support for the conveying component 4, the stacking component 5, and the detection component 6;

[0045] The staff placed empty wet wipe boxes into the conveyor housing 44 one by one, and controlled the air pump 46 to work. The air outlet of the air pump 46 penetrated through the side wall of the conveyor housing 44 and connected to the air inlet of the fixed airbag 45. The fixed airbag 45 was inflated to make it expand. The fixed airbag 45 was used to flexibly limit and fix the wet wipe boxes in the conveyor housing 44 to prevent the wet wipe boxes from shifting or shaking during the conveying process, ensuring accurate alignment of the subsequent stacking station and meeting the positioning accuracy requirements of intelligent packaging equipment.

[0046] Then, the first motor 42 is started. The output end of the first motor 42 passes through the side wall of the corresponding support plate 3 and is fixedly connected to the end of one of the conveyor rollers 41, driving the conveyor roller 41 to rotate. The outer walls of the two conveyor rollers 41 are wrapped with a conveyor belt 43. The conveyor belt 43 is driven by the conveyor rollers 41 to rotate in a cycle, thereby driving the multiple conveyor shells 44 fixed on the outer wall of the belt and the wet wipe boxes with internal limits to be conveyed synchronously. When the first wet wipe box moves with the conveyor shell 44 to the designated stacking position on the side of the fixed plate 51, the first motor 42 is turned off, and the wet wipe box is fixedly stopped and ready for use.

[0047] In the pre-positioning process of the wet wipe box conveyor, the second motor 53 is started in advance. The second motor 53 is fixed to the bottom side wall of the fixed plate 51, and its output end passes through the fixed plate 51 and is connected to the end of the fixed rod 52. The fixed rod 52 is driven to rotate horizontally 180° and then stop to position, so that the mounting plate 54 is accurately positioned directly above the discharge end of the production line. Then the wet wipe pack conveyor is stopped, and the first electric slide rail 55 and the second electric slide rail 58 are started. The first electric slide rail 55 is located on the inner wall of the mounting plate 54 and is slidably connected to the first slide plate 56. The bottom end of the first slide plate 56 is equipped with the second electric slide rail 58 through the mounting block 57. The bottom end of the second electric slide rail 58 is slidably connected to the second slide plate 59. The first slide plate 56 and the second slide plate 59 are driven by the linkage of the two sets of electric slide rails to adjust the plane position, which drives the overall displacement of the lower fixed shell 511, so that the fixed shell 511 is accurately aligned directly above the wet wipe pack to be grabbed at the end of the production line.

[0048] After the positioning is completed, the first electric telescopic rod 510 is activated. The first electric telescopic rod 510 is fixed to the bottom side wall of the second slide plate 59, and its telescopic end is connected to the fixed shell 511. The extension of the first electric telescopic rod 510 drives the fixed shell 511 to move vertically downward, so that the inner clamping plate 513 of the fixed shell 511 is in the clamping position on both sides of the wet wipe pack. Then, multiple sets of second electric telescopic rods 512 arranged on the inner wall of the fixed shell 511 are activated. The telescopic ends of the second electric telescopic rods 512 are fixedly connected to the clamping plate 513, driving the clamping plate 513 to move towards each other to achieve a stable clamping of the side wall of the wet wipe pack. After clamping is completed, the first electric telescopic rod 510 is controlled to retract and reset, driving the wet wipe pack to move upward with the fixed shell 511 and leave the production line discharge station.

[0049] The second motor 53 is started again to drive the fixing rod 52 to rotate 180° and then position it, transferring the fixing shell 511 holding the wet wipe pack to the stacking station of the wet wipe box above the conveyor belt 43; during the transfer process, the detection component 6 is activated to perform intelligent posture detection on the orientation of the top cap opening of the wet wipe pack.

[0050] The detection component 6 is set in the fourth groove 61 opened in the inner wall of one end of the fixed shell 511. The inner wall of the fourth groove 61 is fixed with the third electric slide rail 62. The side wall of the third electric slide rail 62 is slidably connected to the third slide plate 63. The side wall of the third slide plate 63 is fixed with the ninth electric telescopic rod 64. The telescopic end of the ninth electric telescopic rod 64 is connected to the detection plate 65. The side wall of the detection plate 65 is fixed with the tenth electric telescopic rod 66 and the pressure sensor 67 respectively. The telescopic end of the tenth electric telescopic rod 66 is also equipped with the pressure sensor 67. During operation, the tenth electric telescopic rod 66 is controlled to move, causing the end pressure sensor 67 to shift until the distance between the pressure sensor 67 on one side of the tenth electric telescopic rod 66 and the pressure sensor 67 on the side wall of the detection plate 65 matches the appropriate distance between the inner wall of the top cap opening and the side wall of the wet wipe pack for this batch. Then, the tenth electric telescopic rod 66 stops moving. Subsequently, the third electric slide rail 62 is activated to drive the third slide plate 63 to move laterally, so that the tenth electric telescopic rod 66 and the detection structure are aligned to the side of the top cap opening of the wet wipe pack. Then, the ninth electric telescopic rod 64 is controlled to extend, causing the detection plate 65 to approach the side wall of the top cap of the wet wipe pack.

[0051] If the two pressure sensors 67 on the side wall of the detection plate 65 and the end of the tenth electric telescopic rod 66 sense pressure at the same time, it is determined that the opening of the top cover of the wet wipe pack is compliant and no posture adjustment is required; if the pressure sensor 67 on one side of the tenth electric telescopic rod 66 senses pressure first, it is determined that the opening of the cover of the wet wipe pack is off-center and posture correction is required.

[0052] During posture correction, the fourth motor 526 is started. The fourth motor 526 is fixed to the side wall of the U-plate, and its output end passes through the U-plate and is connected to the end of the round rod 525, driving the round rod 525 to rotate. The side rod 527 of the round rod 525 and the clamping plate 528 rotate synchronously. After adjusting the tilt angle of the clamping plate 528 to match the tilt angle of the top cap side wall of the wet wipe pack, the fourth motor 526 is turned off. Then, the fifth electric telescopic rod 521 and the sixth electric telescopic rod 523 are started. The fifth electric telescopic rod 521 is symmetrically fixed to the bottom of the connecting block 520, and its telescopic end is connected to the side plate 522. The sixth electric telescopic rod 523 is located on the opposite side wall of the side plate 522 and its telescopic end is fixed to the U-plate. The linkage drives the U-plate to move, so that the side wall of the clamping plate 528 fits against the top cap side wall of the wet wipe pack, and at the same time, the second groove 529 on the side wall of the clamping plate 528 is aligned with the preset groove on the cap side wall.

[0053] Next, the seventh electric telescopic rod 530 is activated. The seventh electric telescopic rod 530 is located on the inner wall of the second groove 529. The telescopic end drives the locking block 531 to extend into the groove of the side wall of the cap. Then, the eighth electric telescopic rod 533, which is arranged in the third groove 532 at both ends of the locking block 531, is activated. The telescopic end of the eighth electric telescopic rod 533 is fixed with the support block 534. The support block 534 extends out to form a support limit on the inner wall of the cap groove, thus completing the posture locking of the wet wipe pack.

[0054] When the wet wipe pack is facing the correct direction and does not need to be rotated, the clamp 513 can be released from the wet wipe pack and it can be placed down for stacking. When there is a deviation in orientation, the third motor 518 is started. The third motor 518 is located on the inner wall of the fixed frame 517, which is installed on the inner wall of the top of the fixed shell 511. The output end of the third motor 518 is connected to one end of the fourth electric telescopic rod 519, which drives the fourth electric telescopic rod 519 and the bottom connecting block 520 to rotate as a whole, so that the wet wipe pack is adjusted 180° with the rotation action, and the orientation of the cap opening is corrected to the standard posture.

[0055] After the posture correction is completed, the plane position of the fixed shell 511 is adjusted again by the first electric slide rail 55 and the second electric slide rail 58 so that the clamped wet wipe pack is precisely positioned above the preset stacking position inside the wet wipe box; then the fourth electric telescopic rod 519 is extended to move the wet wipe pack down into the wet wipe box to complete the box stacking; after the stacking is in place, the control plate 528, the control block 531 and each adjustment component are reset in sequence.

[0056] Then, adjust the position of the fixed shell 511 so that the third electric telescopic rod 515 and the push plate 516 installed in the first groove 514 at the bottom of the fixed shell 511 move to the top of the stacked wet wipe packs. Start the third electric telescopic rod 515 to extend and drive the push plate 516 to move down, and squeeze the wet wipe packs in the box laterally to make them neat and orderly arranged.

[0057] After a single box of wet wipes is stacked and shaped, all the actuators of the machine are reset, the fixed shell 511 returns to the upper station at the end of the production line, the production line is restored, and the above detection, clamping, orientation, stacking and shaping process is repeated to continuously automate the packing and stacking of subsequent wet wipes. After a single box of wet wipes is full, the conveying component 4 drives the next empty wet wipe box to the stacking station, thus realizing continuous intelligent packing and orderly stacking of wet wipes.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
