Description

Technical Field

[0001] This invention relates to the field of cardboard palletizing technology, and in particular to a palletizing device for producing cardboard packaging boxes. Background Technology

[0002] In the production of cardboard packaging boxes, palletizing is a crucial process involving stacking finished cardboard according to certain rules to facilitate subsequent storage, transportation, or packaging. With the rapid development of the packaging industry, the automation level of cardboard production lines is constantly improving, placing higher demands on the working efficiency, stacking accuracy, and surface quality protection of palletizing equipment.

[0003] Currently, traditional cardboard palletizing equipment mainly uses mechanical pushing, belt conveying combined with baffle positioning, or vacuum suction cup gripping to transport and stack cardboard. For example, a common technical solution is to use a conveyor belt to transport the cardboard to the palletizing station, then use mechanical push rods or cylinder-driven baffles to roughly position the cardboard, and finally use a lifting platform to stack it. However, these existing technologies have revealed many shortcomings in practical applications.

[0004] Firstly, in the cardboard conveying process, traditional belt or roller conveyors require direct contact with the cardboard surface, generating friction. This can easily cause scratches and wear on the cardboard surface, especially the printed or coated side, affecting product quality. For packaging cardboard with high surface finish requirements, the quality defects caused by contact conveying are particularly pronounced. Furthermore, traditional conveying methods struggle to precisely control the cardboard's feed position during high-speed continuous operation, easily leading to cardboard misalignment, overlap, or jamming.

[0005] Secondly, regarding the positioning and posture adjustment of cardboard, most existing equipment can only achieve simple planar limiting or unidirectional pushing, lacking the ability to flexibly adjust the posture of the cardboard in the horizontal and vertical directions. In the production of packaging cardboard, the surface of the cardboard is usually printed with specific identification codes, traceability codes, or location markers. These markings need to be stacked in a uniform direction and position to meet the needs of subsequent packaging, identification, or automated processing. However, due to factors such as conveying direction and orientation during the early cutting and printing processes, the posture of the cardboard may be inconsistent when it enters the palletizing station. Traditional equipment cannot effectively adjust the horizontal rotation angle and vertical flipping angle of the cardboard, making it difficult to unify the labeling or marking positions of all cardboard to the same direction. This brings great inconvenience to the subsequent automated identification and packaging processes, and may even require manual intervention for sorting and adjustment, seriously affecting production efficiency and automation levels.

[0006] Secondly, in the cardboard stacking and palletizing process, most existing equipment's stacking platforms lack real-time monitoring and feedback mechanisms for stacking height. They cannot automatically remind operators to remove finished stacks when the cardboard reaches the predetermined height, easily leading to excessive stacking and deformation or damage to the bottom layer, or disrupting smooth continuous operation due to delayed removal. Furthermore, traditional equipment lacks effective guidance and cushioning for the cardboard's descent onto the palletizing platform, easily causing uneven stacking and damage to edges and corners.

[0007] Finally, from an overall structural perspective, existing palletizing equipment has a low degree of functional module integration, and the connections between various processes are not tight enough, resulting in a large overall footprint, complex structure, and inconvenient maintenance. Especially in production scenarios that require frequent switching of cardboard specifications or adjustment of palletizing direction, the adjustment process of traditional equipment is cumbersome and time-consuming, making it difficult to meet the needs of flexible production.

[0008] In summary, existing cardboard palletizing equipment still has significant shortcomings in non-contact suspended conveying, multi-dimensional adjustment of cardboard posture, unified identification of labeling direction, and automatic monitoring of palletizing height. There is an urgent need to propose a more rational and functional technical solution to achieve high-quality, high-efficiency, and highly automated cardboard palletizing operations. Summary of the Invention

[0009] To address the aforementioned technical problems, the present invention adopts the following technical solution: a palletizing device for producing cardboard packaging boxes, comprising a device housing and an adjusting mechanism for adjusting the position of cardboard to be palletized, the adjusting mechanism comprising a fixed frame fixedly installed inside the device housing, and the adjusting mechanism being provided with a conveying mechanism for conveying the cardboard to be palletized and a palletizing mechanism for palletizing the cardboard.

[0010] Furthermore, the conveying mechanism includes a feeding box fixedly installed inside the equipment housing, a fan fixedly installed below the feeding box, an air duct fixedly installed on the fan, a ring pipe fixedly installed on the air duct, multiple lower air ducts provided inside the feeding box, multiple lower air outlets fixedly installed on the air duct, the lower air outlets connecting to the lower air ducts, and multiple upward-sloping air outlets provided on the ring pipe.

[0011] Furthermore, the conveying mechanism also includes two front blocking electric cylinders fixedly installed on the feed box.

[0012] In use, the cardboard to be stacked is fed into the front of the feed hopper. The blower blows air, and part of the air is blown out through the lower air outlet and the lower air duct, blowing it below the cardboard and causing it to suspend. At the same time, part of the air enters the upper inclined air outlet through the ring pipe and is blown out from the upper inclined air outlet. The air blown out from the upper inclined air outlet provides the power to convey the cardboard forward, transporting the cardboard from the feed hopper to between the two rotating discs. Then, the front blocking electric cylinder extends, and the output end of the front blocking electric cylinder blocks the subsequent cardboard, preventing the subsequent cardboard from affecting the adjustment of the position of the front cardboard in the adjustment mechanism.

[0013] Furthermore, the adjustment mechanism also includes a lower support, on which a friction ring is provided. The friction ring rotates inside the equipment housing. Two connecting brackets are fixedly installed on the friction ring. Multiple lifting electric cylinders are fixedly installed on the connecting brackets. A sleeve is fixedly installed on the output end of the lifting electric cylinder. A support ring is placed on the multiple sleeves. The support ring can move relative to the sleeve. A rotating disk is fixedly installed on the support ring.

[0014] Furthermore, the adjustment mechanism also includes multiple clamping columns slidably mounted on the rotating disk, with clamping plates fixedly mounted on the clamping columns, and clamping springs provided between the clamping columns and the rotating disk.

[0015] Furthermore, the adjustment mechanism also includes multiple limit cylinders fixedly installed on the connecting bracket, and multiple limit holes are provided on the rotating disk.

[0016] Furthermore, the positioning mechanism also includes a horizontal motor fixedly mounted on a fixed frame, a motor wheel fixedly mounted on the motor shaft of the horizontal motor, a side friction wheel rotatably mounted on the fixed frame, an upper transmission wheel fixedly mounted on the motor shaft of the side friction wheel, and a transmission belt wound around the upper transmission wheel and the motor wheel.

[0017] Furthermore, the adjustment mechanism also includes a vertical motor located next to the lower support. A drive gear is fixedly installed on the motor shaft of the vertical motor. Two lower friction wheels and an outer gear are rotatably installed on the lower support. A mating gear is fixedly installed on the lower friction wheel. The mating gear meshes with the outer gear. A transverse transmission belt is wound around the drive gear and the two outer gears. The lower friction wheel and the friction ring form a friction transmission.

[0018] After the cardboard is conveyed between the two rotating disks, the limit cylinder extends, and the output end of the limit cylinder passes through the limit hole and reaches between the two rotating disks. The front-back direction of the cardboard is positioned by the output end of the limit cylinder. Then, the lifting cylinder extends, driving the two support rings and the rotating disk to move inward through the sleeve. The clamping plate first contacts the cardboard, and then the rotating disk continues to move inward, causing the clamping column to slide relative to the rotating disk. The clamping spring is compressed, and the cardboard is clamped by the two clamping plates. Then, the limit cylinder retracts, causing the output end of the limit cylinder to leave the limit hole.

[0019] The labels on the equipment casing are usually located at the same corner. However, due to the different orientations of the cardboard when it is placed, the position of the equipment casing needs to be adjusted. A camera inside the casing observes the position of the labels on the casing, facilitating adjustments to ensure that all cardboard pieces to be stacked have labels in the same position. When the two rotating discs move inward, they engage with the side friction wheels. The horizontal motor drives the motor wheel to rotate, which in turn drives the upper drive wheel and the side friction wheels via a transmission belt. The side friction wheels then drive the rotating discs to rotate, causing the support ring to move relative to the sleeve, and ultimately, the rotating discs to rotate. At this time, the cardboard rotates horizontally, the vertical motor drives the drive gear to rotate, the drive gear drives the outer gear to rotate through the horizontal transmission belt, the outer gear drives the mating gear and the lower friction wheel to rotate, and the lower friction wheel drives the friction ring to rotate, thereby driving the rotating disk and the cardboard to rotate vertically. Through the horizontal and vertical rotation of the cardboard, the labeling position of the cardboard can be adjusted to a uniform position. Then the two rotating disks move outward, the clamping plate no longer clamps the cardboard, at this time the front blocking electric cylinder blows air to transport the cardboard to the fixed frame, and then the next cardboard arrives between the two rotating disks, and so on.

[0020] Furthermore, the palletizing mechanism includes a palletizing upright plate slidably installed in a fixed frame, a palletizing plate fixedly installed below the palletizing upright plate, a palletizing spring provided between the palletizing plate and the fixed frame, a palletizing switch fixedly installed on the fixed frame, a sliding ramp provided inside the fixed frame, and multiple ventilation holes provided on the fixed frame.

[0021] Once the cardboard enters the fixed frame, it reaches the sliding ramp. The cardboard then slides along the sliding ramp onto the stacking plate. Excess air is blown out through the ventilation holes. As more and more cardboard is stacked on the stacking plate, it presses down on the stacking plate and stacking stand, causing the stacking spring to be stretched. When the top of the stacking stand contacts the stacking switch, an alarm is triggered, prompting the staff to remove the stacked cardboard.

[0022] The beneficial effects of this invention compared with the prior art are: (1) In this invention, the conveying mechanism is innovatively set up with a fan, air duct, ring pipe, lower air duct and upward inclined air outlet, etc., and the air force is used to form an air buoyancy support under the cardboard, so that the cardboard is in a suspended state during the conveying process. At the same time, the upward inclined air outlet provides the driving force for forward conveying. This non-contact conveying method completely avoids the friction and squeezing of the cardboard surface caused by traditional belt or roller conveying, and fundamentally eliminates quality defects such as scratches and wear on the cardboard surface. It is especially suitable for packaging cardboard with high surface printing or coating requirements. At the same time, with the timely blocking of the subsequent cardboard by the front blocking electric cylinder, it can effectively prevent the cardboard from overlapping or interfering at the adjustment station, ensuring that the single cardboard enters the subsequent adjustment stage accurately and orderly, and improving the stability of the conveying; (2) In this invention, the adjustment mechanism integrates the horizontal motor driven side friction wheel transmission structure and the vertical motor driven lower friction wheel transmission structure. With the help of the rotating disk, friction ring, support ring and other components, the cardboard can be driven to rotate and adjust in the horizontal and vertical directions respectively after it is clamped and positioned. By using a camera to identify the labeling position of the cardboard in real time, closed-loop feedback control can be achieved, and the labeling position of each cardboard can be precisely adjusted to the same direction. This effectively solves the problem that the cardboard cannot be automatically identified or packaged due to inconsistent incoming material posture, and replaces the traditional manual sorting and adjustment operation method, improving the automation level of the palletizing equipment; (3) The present invention slides and installs clamping columns on the rotating disk and sets clamping springs, so that the clamping plate can generate elastic floating as the rotating disk continues to move after contacting the cardboard, realizing progressive flexible clamping. This structure can provide sufficient clamping force through spring force to ensure that the cardboard does not deviate during horizontal and vertical rotation, and can also avoid the squeezing damage to the edges and corners of the cardboard caused by rigid clamping. At the same time, the design of the limit cylinder and the limit hole can accurately position the cardboard in the front and back directions before clamping, ensuring that the clamping position is consistent each time, providing a reliable basis for subsequent high-precision angle adjustment, thereby ensuring that the entire stack of cardboard is neatly stacked and the labeling direction is highly uniform.

Detailed Implementation

[0034] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0035] Example: Reference Figures 1-10 A palletizing device for producing cardboard packaging boxes includes a housing 4 and an adjusting mechanism for adjusting the position of cardboard to be palletized. The adjusting mechanism includes a fixed frame 201 fixedly installed inside the housing 4. The adjusting mechanism is provided with a conveying mechanism for conveying the cardboard to be palletized and a palletizing mechanism for palletizing the cardboard.

[0036] like Figure 3 , Figure 4As shown, the conveying mechanism includes a feed box 101 fixedly installed inside the equipment housing 4. A fan 102 is fixedly installed below the feed box 101. An air duct 103 is fixedly installed on the fan 102. A ring pipe 105 is fixedly installed on the air duct 103. Multiple lower air ducts 108 are provided inside the feed box 101. Multiple lower air outlets 104 are fixedly installed on the air duct 103. The lower air outlets 104 are connected to the lower air ducts 108. Multiple upward-sloping air outlets 106 are provided on the ring pipe 105.

[0037] like Figure 3 , Figure 4 As shown, the conveying mechanism also includes two front blocking electric cylinders 107 fixedly installed on the feed box 101.

[0038] In use, the cardboard to be stacked is fed into the front of the feed box 101. The blower 102 blows air, and part of the air is blown out through the lower air outlet 104 and the lower air duct 108, blowing it below the cardboard and making the cardboard suspend. At the same time, part of the air enters the upper inclined air outlet 106 through the ring pipe 105 and is blown out from the upper inclined air outlet 106. The air blown out from the upper inclined air outlet 106 provides the power for forward conveying of the cardboard, conveying the cardboard from the feed box 101 to between the two rotating disks 215. Then, the front blocking electric cylinder 107 extends, and the output end of the front blocking electric cylinder 107 blocks the subsequent cardboard, preventing the subsequent cardboard from affecting the adjustment of the position of the front cardboard in the adjustment mechanism.

[0039] like Figures 5-8 As shown, the adjustment mechanism also includes a lower support 207, on which a friction ring 214 is provided. The friction ring 214 rotates inside the equipment housing 4. Two connecting brackets 216 are fixedly installed on the friction ring 214. Multiple lifting electric cylinders 217 are fixedly installed on the connecting brackets 216. A sleeve 219 is fixedly installed on the output end of the lifting electric cylinder 217. A support ring 218 is placed on the multiple sleeves 219. The support ring 218 can move relative to the sleeves 219. A rotating disk 215 is fixedly installed on the support ring 218.

[0040] like Figures 5-8 As shown, the adjustment mechanism also includes multiple clamping columns 222 that are slidably mounted on the rotating disk 215. A clamping plate 223 is fixedly mounted on the clamping column 222, and a clamping spring 224 is provided between the clamping column 222 and the rotating disk 215.

[0041] like Figures 5-8 As shown, the adjustment mechanism also includes multiple limit electric cylinders 220 fixedly installed on the connecting bracket 216, and multiple limit holes 221 are provided on the rotating disk 215.

[0042] like Figures 5-8As shown, the adjustment mechanism also includes a horizontal motor 202 fixedly installed on the fixed frame 201. A motor wheel 203 is fixedly installed on the motor shaft of the horizontal motor 202. A side friction wheel 205 is rotatably installed on the fixed frame 201. An upper transmission wheel 206 is fixedly installed on the motor shaft of the side friction wheel 205. A transmission belt 204 is wound around the upper transmission wheel 206 and the motor wheel 203.

[0043] like Figures 5-8 As shown, the adjustment mechanism also includes a vertical motor 208 located next to the lower support 207. A drive gear 209 is fixedly installed on the motor shaft of the vertical motor 208. Two lower friction wheels 211 and an outer gear 212 are rotatably installed on the lower support 207. A mating gear 213 is fixedly installed on the lower friction wheel 211. The mating gear 213 meshes with the outer gear 212. A horizontal transmission belt 210 is wound around the drive gear 209 and the two outer gears 212. The lower friction wheel 211 and the friction ring 214 form a friction transmission.

[0044] After the cardboard is conveyed between the two rotating disks 215, the limiting electric cylinder 220 extends. The output end of the limiting electric cylinder 220 passes through the limiting hole 221 and reaches between the two rotating disks 215. The output end of the limiting electric cylinder 220 positions the cardboard in the front-back direction. Then, the lifting electric cylinder 217 extends, driving the two support rings 218 and the rotating disk 215 to move inward through the sleeve 219. The clamping plate 223 first contacts the cardboard, and then the rotating disk 215 continues to move inward, causing the clamping column 222 to slide relative to the rotating disk 215. The clamping spring 224 is compressed, and the cardboard is clamped by the two clamping plates 223. Then, the limiting electric cylinder 220 retracts, causing the output end of the limiting electric cylinder 220 to leave the limiting hole 221.

[0045] The labels on the equipment casing 4 are usually located at the same corner. However, due to the different orientations of the cardboard when it is placed, the position of the equipment casing 4 needs to be adjusted. The position of the labels on the equipment casing 4 is observed by a camera inside the equipment casing 4, which facilitates the adjustment of the position of the equipment casing 4 so that the labels of all cardboard to be stacked are in the same position. When the two rotating disks 215 move inward, the rotating disks 215 are in contact with the side friction wheels 205. The horizontal motor 202 drives the motor wheel 203 to rotate. The motor wheel 203 drives the upper transmission wheel 206 and the side friction wheel 205 to rotate through the transmission belt 204. The side friction wheel 205 drives the rotating disks 215 to rotate. The support ring 218 moves relative to the sleeve 219, and the rotating disks 215 rotate. At this time, the cardboard rotates horizontally, and the vertical motor 208 drives the drive gear 209 to rotate. The drive gear 209 drives the outer gear 212 to rotate through the horizontal transmission belt 210. The outer gear 212 drives the mating gear 213 and the lower friction wheel 211 to rotate. The lower friction wheel 211 drives the friction ring 214 to rotate, thereby driving the rotating disk 215 and the cardboard to rotate vertically. Through the horizontal and vertical rotation of the cardboard, the labeling position of the cardboard can be adjusted to a unified position. Then, the two rotating disks 215 move outward, and the clamping plate 223 no longer clamps the cardboard. At this time, the front blocking electric cylinder 107 blows air to transport the cardboard to the fixed frame 201. Then, the next cardboard arrives between the two rotating disks 215, and so on.

[0046] like Figures 9-10 As shown, the palletizing mechanism includes a palletizing upright plate 302 slidably installed in a fixed frame 201, a palletizing plate 301 fixedly installed below the palletizing upright plate 302, a palletizing spring 303 provided between the palletizing plate 301 and the fixed frame 201, a palletizing switch 304 fixedly installed on the fixed frame 201, a sliding ramp 306 provided inside the fixed frame 201, and multiple ventilation holes 305 provided on the fixed frame 201.

[0047] After the cardboard enters the fixed frame 201, it reaches the slide ramp 306. Then, the cardboard slides along the slide ramp 306 onto the stacking plate 301. Excess air is blown out from the ventilation hole 305. As more and more cardboard is on the stacking plate 301, it will press down the stacking plate 301 and the stacking upright plate 302, causing the stacking spring 303 to be stretched. When the top of the stacking upright plate 302 contacts the stacking switch 304, an alarm is sounded, prompting the staff to remove the cardboard that has been stacked.

[0048] Working principle: During use, the cardboard to be stacked is fed into the front end of the feed box 101. The blower 102 blows air, and part of the air is blown out through the lower air outlet 104 and the lower air duct 108, which blows the cardboard below, causing the cardboard to suspend. At the same time, part of the air enters the upper inclined air outlet 106 through the ring pipe 105 and is blown out from the upper inclined air outlet 106. The air blown out from the upper inclined air outlet 106 provides the power for forward conveying of the cardboard, conveying the cardboard from the feed box 101 to between the two rotating disks 215. Then, the front blocking electric cylinder 107 extends, and the output end of the front blocking electric cylinder 107 blocks the subsequent cardboard, preventing the subsequent cardboard from affecting the adjustment of the position of the front cardboard in the adjustment mechanism.

[0049] After the cardboard is conveyed between the two rotating disks 215, the limiting electric cylinder 220 extends. The output end of the limiting electric cylinder 220 passes through the limiting hole 221 and reaches between the two rotating disks 215. The output end of the limiting electric cylinder 220 positions the cardboard in the front-back direction. Then, the lifting electric cylinder 217 extends, driving the two support rings 218 and the rotating disk 215 to move inward through the sleeve 219. The clamping plate 223 first contacts the cardboard, and then the rotating disk 215 continues to move inward, causing the clamping column 222 to slide relative to the rotating disk 215. The clamping spring 224 is compressed, and the cardboard is clamped by the two clamping plates 223. Then, the limiting electric cylinder 220 retracts, causing the output end of the limiting electric cylinder 220 to leave the limiting hole 221. The labels on the equipment casing 4 are usually located at the same corner. However, due to the different orientations of the cardboard when it is placed, the position of the equipment casing 4 needs to be adjusted. The position of the labels on the equipment casing 4 is observed by a camera inside the equipment casing 4, which facilitates the adjustment of the position of the equipment casing 4 so that the labels of all cardboard to be stacked are in the same position. When the two rotating disks 215 move inward, the rotating disks 215 are in contact with the side friction wheels 205. The horizontal motor 202 drives the motor wheel 203 to rotate. The motor wheel 203 drives the upper transmission wheel 206 and the side friction wheel 205 to rotate through the transmission belt 204. The side friction wheel 205 drives the rotating disks 215 to rotate. The support ring 218 moves relative to the sleeve 219, and the rotating disks 215 rotate. At this time, the cardboard rotates horizontally, and the vertical motor 208 drives the drive gear 209 to rotate. The drive gear 209 drives the outer gear 212 to rotate through the horizontal transmission belt 210. The outer gear 212 drives the mating gear 213 and the lower friction wheel 211 to rotate. The lower friction wheel 211 drives the friction ring 214 to rotate, thereby driving the rotating disk 215 and the cardboard to rotate vertically. Through the horizontal and vertical rotation of the cardboard, the labeling position of the cardboard can be adjusted to a unified position. Then, the two rotating disks 215 move outward, and the clamping plate 223 no longer clamps the cardboard. At this time, the front blocking electric cylinder 107 blows air to transport the cardboard to the fixed frame 201. Then, the next cardboard arrives between the two rotating disks 215, and so on.

[0050] After the cardboard enters the fixed frame 201, it reaches the slide ramp 306. Then, the cardboard slides along the slide ramp 306 onto the stacking plate 301. Excess air is blown out from the ventilation hole 305. As more and more cardboard is on the stacking plate 301, it will press down the stacking plate 301 and the stacking upright plate 302, causing the stacking spring 303 to be stretched. When the top of the stacking upright plate 302 contacts the stacking switch 304, an alarm is sounded, prompting the staff to remove the cardboard that has been stacked.
