Description

Technical Field

[0001] The invention relates to the technical field of conveying and palletizing finished carton-packed products, and in particular to a device for conveying and palletizing finished carton-packed products. Background Art

[0002] After producing and processing qualified finished products, processing plants usually package the qualified finished products in cartons, and stack the cartons packed with finished products together to facilitate subsequent batch transportation; when palletizing the carton-packed finished products, processing plants usually use robotic arms to clamp the carton-packed finished products on the conveying equipment, and use the robotic arms to stack the clamped carton-packed finished products from top to bottom on pallets used for support and transportation, and finally use forklifts and other transportation equipment to transport pallets with a certain number of carton-packed finished products.

[0003] In the prior art, when the finished carton packaging products are clamped and placed by a robotic arm, since the two sides of the finished carton packaging products need to be clamped by clamping plates, a certain space needs to be reserved between the two stacks of cartons for the movement of the clamping plates during the placement process; when the finished carton packaging products are clamped by the robotic arm and placed, in order to ensure the stability of the overall stacking, the clamped finished carton packaging products to be placed usually maintain a certain distance from the finished carton packaging products that have been placed on the lower side, so as to avoid the deviation or falling of the finished carton packaging products due to friction or collision between the two finished carton packaging products.

[0004] However, the traditional method of batch stacking carton packaging products by robotic arms has the following problems: 1. The method of gripping and placing carton packaging products by robotic arms usually requires the robotic arms to constantly adjust their movement trajectory to adapt to the carton packaging products in the material-to-be-picked area on the conveying equipment and the constantly changing placement positions of the carton packaging products on the pallet, which results in the overall movement trajectory of the robotic arms being more complicated, the overall operation being more cumbersome, and the operation accuracy requirements being higher, which in turn results in the overall operation and maintenance costs of the equipment being higher, and the overall stacking efficiency of the carton packaging products needs to be improved; 2. When the robotic arms grip and place the carton packaging products, a space needs to be left for the splint. 1. When the robot arm places the finished carton-packed products, the clamped carton-packed products will fall a certain distance before they can be placed, which will cause the finished products in the carton to shake due to the vibration caused by the fall. If the finished products in the carton are easily damaged, the risk of damage to the finished products in the carton will be greatly increased, which will affect the overall quality of the product and the cost of production and processing.

The openings of the symmetrical U-shaped frames 12 are arranged in opposite directions. Conveying rollers 13 are rotatably arranged on the inner side of the positioning frame 11 and between the symmetrical U-shaped frames 12. A fixing frame 14 is symmetrically fixedly arranged on the positioning frame 11 and on the rear side of the U-shaped frame 12. A front baffle 15 is fixedly arranged at the front end of the positioning frame 11.

[0035] See also Figure 2 The material taking mechanism 2 includes a mounting frame 24 and a mounting frame 1 21 which are fixedly arranged up and down together on the rear side of a left-right symmetrical fixing frame 14. A lifting assembly 22 is arranged on the mounting frame 1 21, a material taking assembly 23 is arranged on the lower side of the lifting assembly 22, and a material pushing assembly 25 is arranged on the mounting frame 24.

[0036] See also Figure 4 , Figure 5 and Figure 6 The lifting assembly 22 includes a hydraulic cylinder 221 fixedly arranged on the upper side of the mounting frame 21, a U-shaped plate 222 that moves up and down is fixedly arranged on the telescopic end of the hydraulic cylinder 221, wherein the opening of the U-shaped plate 222 faces forward, an adjusting platform 223 is fixedly arranged on the upper side of the U-shaped plate 222 symmetrically, an L-shaped adjusting plate 224 is symmetrically slidably arranged on the opposite side of the symmetrical adjusting platform 223, a plurality of limiting rollers 225 are uniformly rotated up and down on the opposite side of the vertical section of the symmetrical L-shaped adjusting plate 224 through a support, an adjusting rod 226 that is slidably connected to the corresponding adjusting platform 223 is fixedly arranged on the opposite side of the vertical section of the symmetrical L-shaped adjusting plate 224 symmetrically up and down, a plurality of positioning holes 227 that penetrate up and down are uniformly opened on the adjusting rod 226, and the positioning hole 227 is docked and positioned with the corresponding adjusting platform 223 through a latch.

[0037] The U-shaped plate 222 and the adjustment platform 223 are driven downward by the hydraulic cylinder 221, and the left-right symmetrical L-shaped adjustment plate 224 drives the corresponding limiting rollers 225 to move downward synchronously along the left and right sides of the finished carton packaging product, so that the two sides of the finished carton packaging product can be stably limited by the left-right symmetrical multiple limiting rollers 225; when the left and right sides of the finished carton packaging products of different widths need to be limited, the corresponding L-shaped adjustment plate 224 is slidably adjusted by the adjustment rod 226, so that the left-right symmetrical L-shaped adjustment plates 224 are synchronously moved relative to or away from each other by the same distance to adapt to the finished carton packaging products of corresponding widths, and the L-shaped adjustment plate 224 and the limiting rollers 225 are stably positioned together with the corresponding adjustment platform 223 by inserting the latch into the corresponding positioning hole 227.

[0038] See also Figure 5 and Figure 6 The material picking assembly 23 includes a material picking seat 231 fixedly arranged on the lower side of the horizontal section of the corresponding L-shaped adjustment plate 224, a spring rod 232 is elastically and slidably arranged on the material picking seat 231 in a front-to-back symmetrical manner, a connecting plate 233 is fixedly arranged on one end of the front-to-back symmetrical spring rod 232 close to the conveying frame 1, a connecting rod 234 is fixedly arranged on the side of the connecting plate 233 away from the spring rod 232 in a front-to-back symmetrical manner, a wedge block 235 is fixedly arranged on one end of the front-to-back symmetrical connecting rod 234 away from the connecting plate 233, a side of the wedge block 235 away from the connecting rod 234 is an inclined surface, and a plurality of balls are uniformly rolled on the upper surface and tip of the wedge block 235.

[0039] When the finished carton packaging products are to be picked up at a fixed point, the stacking mechanism 5 is first enabled to fit and limit the front side of the finished carton packaging products being picked up, and then the finished carton packaging products are transported to the upper side of the U-shaped frame 12 by the conveying roller 13 and the front side of the finished carton packaging products is stably limited by the front baffle 15. Then, the U-shaped plate 222 and the adjustment platform 223 are driven downward by the hydraulic cylinder 221, and the L-shaped adjustment plate 224 drives the limiting roller 225 and the picking seat 231 to move downward synchronously. Under the cooperation limit of mechanism 3, the paired spring rods 232 first drive the left and right symmetrical wedge blocks 235 to move synchronously in the process of moving downward through the corresponding connecting plate 1 233 and connecting rod 1 234, until the ball on the tip of the wedge block 235 can contact the corresponding side surface of the carton packaging product, and when the ball on the tip of the wedge block 235 contacts the upper end of the corresponding side surface of the carton packaging product, the spring rod 1 232 also just breaks away from the cooperation limit of the limiting mechanism 3. At this time, the spring rod 1 232 drives the corresponding wedge block 235 to stick to the corresponding side surface of the carton packaging product, and with the continuous driving of the hydraulic cylinder 1 221, the spring rod 1 232 and the wedge block 235 continue to move downward along the carton packaging product until the wedge block 235 moves to the bottom of the carton packaging product, and at this time, the corresponding limiting rollers 225 have also been fitted and limited to the left and right sides of the carton packaging product. Under the action of the spring rod 1 232, the left and right symmetrical wedge blocks 235 move relative to each other. It moves into the opening of the corresponding U-shaped frame 12 and fits with the lower surface of the finished carton packaging product, and finally drives the wedge block 235 to move upward through the hydraulic cylinder 221. The wedge block 235 then stably lifts the finished carton packaging product upward to take out the material, and when the wedge block 235 is separated from the corresponding U-shaped frame 12, the spring rod 232 will further drive the left and right symmetrical wedge blocks 235 to move relatively by a certain distance, so that the spring rod 232 can be docked with the limit mechanism 3 again when it moves to the highest point.

[0040] Before taking the finished carton packaging product to be taken on the upper side of the U-shaped frame 12, if there is a finished carton packaging product to be taken on the left-right symmetrical wedge block 235, the wedge block 235 is driven downward by the hydraulic cylinder 1 221, and the finished carton packaging product will first move downward synchronously with the wedge block 235, and in the process of the left-right symmetrical wedge blocks 235 moving away from each other, the finished carton packaging product will gradually move downward slowly along the inclined surface on the wedge block 235 until the tip of the wedge block 235 can contact the corresponding side surface of the finished carton packaging product to be taken on the lower side, at this time, the lower surface of the finished carton packaging product on the upper side that has been taken just fits with the upper surface of the finished carton packaging product to be taken on the lower side, so that the two finished carton packaging products are stably placed up and down together, and then the wedge block 23 is driven by the hydraulic cylinder 1 221 to move downward. 5 moves, so that the wedge block 235 drives the two upper and lower placed carton packaging products to move upward synchronously by holding up the carton packaging product to be taken out, until the spring rod 1 232 moves to the highest point again and docks with the limiting mechanism 3. The above-mentioned method of taking out and placing the carton packaging products can not only realize the fixed-point taking of the carton packaging products conveyed on the conveyor frame 1, but also can stack and place the multiple carton packaging products that are taken out at the fixed point from bottom to top in sequence by repeating a single running trajectory, thereby realizing stable taking out and rapid stacking and placing of the carton packaging products at a fixed position, and by stacking and placing the carton packaging products from bottom to top, the carton packaging products can be prevented from falling a certain distance during the placing process, thereby eliminating the risk of damage to the finished products packaged in the carton due to falling vibration.

[0041] See also Figure 4 The pushing assembly 25 includes a hydraulic cylinder 251 fixedly arranged on the rear side of the mounting frame 24, a pushing plate 252 that moves forward and backward is fixedly arranged at the telescopic end of the hydraulic cylinder 251, and a correction plate 253 that tilts backward is fixedly arranged at the lower end of the pushing plate 252.

[0042] When the push plate 252 is driven by the hydraulic cylinder 251 to push a stack of finished carton packaging products on the wedge block 235 forward, the ball bearings on the upper surface of the wedge block 235 can greatly reduce the resistance to the forward movement of the finished carton packaging products, thereby greatly improving the stability of the movement of the stack of finished carton packaging products, wherein the push plate 252 can limit the rear side of the finished carton packaging products during the process of being lifted up, and the correction plate 253 at the lower end of the push plate 252 can correct and align the lifted carton packaging products, and the push plate 252 and the correction plate 253 can be adjusted forward and backward by the hydraulic cylinder 251 to adapt to carton packaging products of different lengths.

[0044] See also Figure 6 The adjustment component 31 includes a guide rod 311 which is symmetrically fixed on the positioning frame 11 and located on the front and rear sides of the corresponding U-shaped frame 12. A plurality of vertically penetrating positioning holes 312 are evenly opened on the left and right sides of the guide rod 311, wherein the spacing between two adjacent positioning holes 312 is the same as the spacing between two adjacent positioning holes 1 227. A sliding frame 313 is slidably arranged on the front and rear symmetrical guide rods 311. The sliding frame 313 is docked and positioned with the corresponding positioning hole 312 through a second latch, and a second connecting plate 314 is fixedly arranged on the upper side of the sliding frame 313.

[0045] See also Figure 5 , Figure 6 and Figure 7 The limit assembly 32 includes a limit plate 321 symmetrically fixedly arranged on the connecting plate 2 314 near the conveying frame 1, and the limit grooves are arranged on the opposite sides of the symmetrical limit plates 321. The limit grooves are composed of a vertically distributed sliding groove 322, a docking groove 323 penetrating downward at the lower end of the sliding groove 322, and a guide groove 324 extending away from the conveying frame 1 at the upper end of the sliding groove 322. The docking groove 323 is composed of three inclined surfaces, and the guide groove 324 is composed of an inclined upper part. The groove and the lower half are composed of a straight groove that passes downward, and the depth of the guide groove 324 is greater than the depth of the sliding groove 322. A connecting plate 325 is fixedly arranged on the end of the front-to-back symmetrical spring rod 1 232 away from the conveying frame 1. A spring sleeve 326 is fixedly arranged on the side of the connecting plate 325 away from the spring rod 1 232 through a support 2. An elastic clip 327 that extends backward and slides with the corresponding limit groove is elastically slidably arranged in the front-to-back symmetrical spring sleeve 326.

[0046] When the left-right symmetrical L-shaped adjustment plates 224 move the same distance relative to or away from each other to adapt to the finished carton packaging product of corresponding width, the left-right symmetrical sliding frame 313 needs to be synchronously moved and adjusted to the same distance, and the sliding frame 313 is stably positioned by inserting the second pin into the corresponding positioning hole 312 to ensure that the spring sleeve 326 and the elastic clip 327 that move synchronously with the spring rod 1 232 can always be docked and matched with the limit groove.

[0047] When the spring sleeve 326 moves downward synchronously with the spring rod 1 232 corresponding to the highest point, the elastic clip 327 moves downward along the corresponding guide groove 324 until it is completely disengaged, and the connecting plate 325 drives the paired spring rod 1 232 to move a certain distance in the direction away from the conveying frame 1, so that the left and right symmetrical wedge blocks 235 move back to each other until the tip of the wedge block 235 can contact the corresponding side surface of the carton packaging product to be taken out at the lower side; when the wedge block 235 drives the carton packaging product to be taken out to continue to move upward to the highest point, the elastic clip 327 aligned with the corresponding sliding groove 322 moves upward synchronously until the elastic clip 327 cooperates with the corresponding docking groove 323 and slides into the upper end of the guide groove 324 through the corresponding sliding groove 322, and at the same time, under the action of the corresponding spring sleeve 326, the elastic clip 327 is inserted into the upper end of the corresponding guide groove 324.

[0052] Before the wedge block 235 picks up and places the finished carton packaging products, the electric slider 515 first drives the moving frame 512 to move leftward along the guide rail 511 until the rotating roller 2 536 on the right end limit frame 535 can fit and limit the front side of the finished carton packaging products being picked up upward, and then the wedge block 235 is driven to continuously pick up and place the finished carton packaging products up and down until a stack of a specific number of finished carton packaging products is placed, and then the push plate 252 is driven to push the stack of finished carton packaging products forward, and the stack of finished carton packaging products moves forward from the wedge block 235 to the rotating roller 1 525, wherein the rotating roller 1 525 can also greatly reduce the resistance encountered by the finished carton packaging products during the forward movement, until the stack of finished carton packaging products is completely stacked to The rotating roller 253 is above the rotating roller 1 525, and the rotating roller 2 536 and its corresponding rack 538 attached to the front side of the stack of finished carton packaging products also move forward a certain distance synchronously. Under the action of the spring rod 2 533, the tooth block 534 can continuously engage with the corresponding rack 538 to ensure that the rack 538 and the corresponding rotating roller 2 536 cannot continue to move without the action of external force, so that the corresponding rotating roller 2 536 can always be stably limited at the front side of the stack of finished carton packaging products. At this time, the pushing plate 252 can be moved backward and reset and continue to drive the wedge block 235 to continuously pick up and put up and down a new stack of finished carton packaging products. At this time, the stack of finished carton packaging products can fit and limit the front side of the new round of picked up carton packaging products.

[0053] When a new stack of finished carton packaging products is completed and stacked, it is pushed forward to the top of the rotating roller 525 by the pushing plate 252 again and tightly fits together with the stack of finished carton packaging products on the front side. When a row of several stacks of finished carton packaging products that are tightly fitted front and back are stacked on the rotating roller 525, the electric slider 515 drives the moving frame 512 to move rightward by a certain distance again, so that the rotating roller 2 536 on the adjacent limiting frame 535 on the left can fit and limit the front side of the taken carton packaging product. At this time, a row of several stacks of finished carton packaging products that are tightly fitted front and back can continue to be stacked on the rotating roller 525. Finished products are stacked until the top of the pallet 521 is fully stacked with carton-packaged finished products, and the distance between the two adjacent stacks of carton-packaged finished products can be reduced as much as possible by controlling the moving distance of the movable frame 512. The above-mentioned stacking method can realize the close stacking of the front and rear adjacent stacks of carton-packaged finished products together, and can realize the reduction of the placement distance between the left and right adjacent stacks of carton-packaged finished products as much as possible, thereby greatly reducing the shaking space between each stack of carton-packaged finished products, thereby improving the overall stability and safety of the carton-packaged finished products during transportation, and further ensuring the transportation quality of the products and the overall production and processing costs.

[0054] When the finished carton-packed products stacked on the upper side of the rotating roller 525 are to be transported, the picking fork on the forklift is first inserted into the corresponding fork slot 522 from right to left, and the pallet 521 is lifted upward by the picking fork. The pallet 521 then stably lifts the finished carton-packed products stacked on the upper side of the rotating roller 525 upward until the finished carton-packed products are completely separated from the rotating roller 525. At this time, the pallet 521 and the finished carton-packed products stacked on the upper side of the pallet 521 can be synchronously taken out to the right by the forklift, so that the finished carton-packed products can be transported by the forklift.
