DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Please refer to Figure 1 and Figure 2 As shown, the present invention provides an automatic sorting and stacking device for printed materials, comprising a work area dividing plate 1 located on a horizontal ground in a workshop, two parallelly arranged conveying mechanisms 2 are placed at the upper rear position of the work area dividing plate 1, the upper middle part of the work area dividing plate 1 is a mechanical handling area, the mechanical handling area comprises a mechanical handling arm 3 fixed to the work area dividing plate 1 by bolts, the end of the mechanical handling arm 3 is connected with an adaptive adsorption mechanism 4 that can adapt to bundles of printed materials on different upper surfaces, two material sorting mechanisms 5 are placed at the upper front position of the work area dividing plate 1, the internal stacking of the material sorting mechanism 5 located on the right side has bundles of printed materials 6, and the internal stacking of the material sorting mechanism 5 located on the left side has bundles of printed materials 7.

[0034] The present invention drives the adaptive adsorption mechanism 4 to move in three-dimensional space through the mechanical handling arm 3, and can use the adaptive adsorption mechanism 4 to adsorb the bundled printed matter 1 6 or the bundled printed matter 2 7 transported from the conveying mechanism 2. The adaptive adsorption mechanism 4 can sort and stack the bundled printed matter 1 6 or the bundled printed matter 2 7 into the material sorting mechanism 5, and finally the forklift can transport the material sorting mechanism 5 with the stacked goods to a suitable position.

[0035] Please refer to Figure 3 and Figure 4 As shown, the adaptive adsorption mechanism 4 includes a mounting assembly 45 connected to the end of the mechanical handling arm 3, the bottom of the mounting assembly 45 is fixedly connected to the load-bearing assembly 41, the bottom rear position of the load-bearing assembly 41 is slidably connected to two secondary adjustment assemblies 42 located on the same horizontal line, the bottom front position of the load-bearing assembly 41 is slidably connected to two follower assemblies 43 located on the same horizontal line, the two secondary adjustment assemblies 42 and the two follower assemblies 43 are distributed in a rectangular shape, and the secondary adjustment assembly 42 and the follower assembly 43 are both driven by the primary adjustment assembly 44 installed above the load-bearing assembly 41.

[0036] Due to the difference in upper surface areas of bundled printed matter 1 6 and bundled printed matter 2 7, using the same adsorption mechanism will result in poor adsorption effect, unstable center of gravity, and easy falling of materials. Therefore, the present invention designs an adaptive adsorption mechanism 4 that can stably adsorb bundled printed matter with different upper surface areas. The present invention can adjust the positions of the four suction cups according to the identified upper surface area information of the bundled printed matter, so that the four suction cups are located near the four top corners of the upper surface of the bundled printed matter, thereby ensuring the stability of the suction cups when adsorbing the bundled printed matter, and avoiding the unstable center of gravity of the bundled printed matter and the falling of materials due to adsorption problems during transportation.

[0037] Please refer to Fig. 9 As shown, the mounting assembly 45 includes a connecting plate 453 fixedly connected to the end of the mechanical handling arm 3, a mounting plate 451 is fixedly mounted on the bottom of the connecting plate 453, and four rectangularly distributed columns 452 are fixedly mounted on the bottom of the mounting plate 451; by setting the mounting assembly 45, the present invention can install the bearing assembly 41 on the end of the mechanical handling arm 3 through the mounting assembly 45, thereby playing a connecting role.

[0038] Please refer to Figure 5 As shown, the bearing assembly 41 includes a bearing plate 411 fixedly connected to the bottom of the column 452, a sorting scanning device 412 is fixedly installed in the middle of the lower surface of the bearing plate 411, four strip cavities 413 are opened on the bearing plate 411, and the angle between adjacent strip cavities 413 is a right angle; a guide rod 414 is fixedly installed inside each of the strip cavities 413, two L-shaped slide grooves 415 are opened on the front and rear sides of the bearing plate 411, and an L-shaped slider 416 is slidably connected inside each L-shaped slide groove 415, and a guide column 417 is fixedly installed between the two L-shaped sliders 416 on the left and between the two L-shaped sliders 416 on the right.

[0039] The present invention can scan the QR code on the bundled printed matter at the front end of the conveying mechanism 2 through the sorting scanning device 412 inside the adaptive adsorption mechanism 4, and the sorting scanning device 412 will identify the type of the bundled printed matter and the area of ​​the upper surface of the bundled printed matter. The bundled printed matter can be transported to the sorting mechanism 5 at the corresponding position according to the identified type of the bundled printed matter, and the positions of the four suction cups can be adjusted according to the identified area of ​​the upper surface of the bundled printed matter, so that the adaptive adsorption mechanism 4 can better adsorb the bundled printed matter; the two secondary adjustment components 42 and the two follower components 43 can be guided to gather inward or spread outward through the arrangement of the strip cavity 413 and the guide rod 414; the secondary adjustment component 42 and the follower component 43 can be moved in the left and right directions through the arrangement of the L-shaped slide groove 415 and the L-shaped slider 416, and the secondary adjustment component 42 and the follower component 43 can be moved in the front and rear directions through the arrangement of the guide column 417.

[0040] Please refer to Figure 6 As shown, the secondary adjustment component 42 includes a square slider 421, a guide hole 422 is provided inside the square slider 421 for slidingly cooperating with the guide rod 414, a boss 423 is fixedly installed on the top of the square slider 421, a bar frame 424 is connected to the bottom of the square slider 421 through a fixed disk, a screw rod 425 is rotatably connected inside the bar frame 424, a moving block 426 is threadedly connected to the outer side of the screw rod 425, and the screw rod 425 is driven by a motor fixedly installed on one end face of the bar frame 424. A connecting block 427 is fixedly installed at the bottom of the movable block 426, and a through hole 428 for penetrating the guide column 417 is opened inside the connecting block 427. An electric-controlled suction cup 429 is fixedly installed at the bottom of the connecting block 427. By starting the motor installed on the bar frame 424, the motor drives the lead screw 425 to rotate, so that the movable block 426 moves to the left or right, thereby driving the electric-controlled suction cup 429 to move to the left or right, thereby completing further adjustment of the electric-controlled suction cup 429 in the left and right directions.

[0041] Please refer to Figure 6 and Figure 7 As shown, the difference between the follower assembly 43 and the secondary adjustment assembly 42 is that a horizontal rod 431 is fixedly installed inside the bar frame 424 on the follower assembly 43, and a second moving block 432 is slidably sleeved on the outer side of the horizontal rod 431, and the rest of the structures are the same.

[0042] Please refer to Figure 8As shown, the first-stage adjustment component 44 includes a fixing frame 441 fixedly mounted above the supporting plate 411, a through shaft 442 passes through the middle of the fixing frame 441, a turntable 443 is fixedly mounted on the bottom of the through shaft 442, and four arc-shaped holes 444 which are plugged into the boss 423 are opened on the turntable 443, and the through shaft 442 is driven by an actuator motor 445 fixedly mounted above the fixing frame 441; the present invention can drive the second-stage adjustment component 42 and the follower component 43 by setting the first-stage adjustment component 44.

[0043] In the present invention, when the four electric-controlled suction cups 429 are located in the center and close to each other, although it can be suitable for most bundles of printed materials, when the upper surface area of ​​the bundle of printed materials is large, since the four electric-controlled suction cups 429 are relatively centered, the bundle of printed materials may shake due to unstable center of gravity during transportation, causing the bundle of printed materials to fall. Therefore, in order to stably adsorb bundles of printed materials with different upper surface areas, the present invention designs an adaptive adsorption mechanism 4 that can adjust the positions of the four electric-controlled suction cups 429 according to the size of the upper surface area of ​​the bundle of printed materials. The specific adjustment method is as follows: by starting the execution motor 445, the execution motor 445 can drive the turntable 443 to rotate through the through shaft 442. Since the convex column 423 is inserted into the inside of the arc-shaped hole 444 on the turntable 443, when the turntable 443 rotates, the four convex columns 423 can be gathered or relative to each other. The electric suction cups 429 are moved away from each other, thereby making the four electric suction cups 429 gather together or move away from each other, and at this time, the synchronous adjustment of the electric suction cups 429 in the front, rear, left and right directions can be completed. In addition, when it is necessary to further adjust the electric suction cups 429 in the left and right directions, the motor installed on the bar frame 424 is started, and the motor drives the screw rod 425 to rotate, so that the moving block 426 moves left or right, thereby driving the electric suction cups 429 to move left or right, thereby completing the further adjustment of the electric suction cups 429 in the left and right directions. In addition, since the two electric suction cups 429 on the left side and the two electric suction cups 429 on the right side can slide in the left and right directions through the L-shaped slider 416, the two electric suction cups 429 on the front side and the two electric suction cups 429 on the rear side can slide in the front and rear directions through the guidance of the guide column 417, the position adjustment of the two secondary adjustment components 42 and the two follower components 43 can be realized.

[0044] Please refer to Fig.10 As shown, the material-forming mechanism 5 includes a limit assembly 51 located on the work area dividing plate 1, and the limit assembly 51 is driven by a driving assembly 52; please refer to Fig.11As shown, the limiting assembly 51 includes a material tray 511 placed on the work area dividing plate 1, and two plug-in holes 512 corresponding to the front plug-in plate of the forklift are opened inside the material tray 511, and a pad plate 513 is fixedly installed in the middle of the upper surface of the material tray 511, and a limiting frame 514 for limiting the bundled printed materials is arranged directly above the material tray 511, and the height of the pad plate 513 is higher than the height of the limiting frame 514 when it is folded, and placement holes 515 are opened on the four borders of the limiting frame 514, and a straight rod 516 is fixedly installed inside the placement hole 515, and a straight block 517 is slidably sleeved on the outer side of the straight rod 516, and the straight block 517 The bottom is movably connected to the upper surface of the supporting tray 511 through an inclined rod 518, the bottom end of the inclined rod 518 is connected to the upper surface of the supporting tray 511 through a hinge seat, and the top of the inclined rod 518 is connected to the bottom of the straight block 517 through another hinge seat; the present invention sets a cushioning plate 513, and since the height of the cushioning plate 513 is higher than the height of the limit frame 514 when it is folded, when the bundled printed materials are unloaded later, the obstruction of the limit frame 514 can be avoided, thereby facilitating the unloading; through the combined use of four groups of placement holes 515, the straight rod 516, the straight block 517 and the inclined rod 518, the limit frame 514 can be guided to realize the lifting and lowering of the limit frame 514 in the vertical direction.

[0045] Please refer to Fig.12 As shown, the driving assembly 52 includes a bottom block 521 fixedly mounted above the supporting tray 511 and a top block 522 fixedly mounted on the side of the limiting frame 514, and a multi-stage electric telescopic rod 523 is movably connected between the bottom block 521 and the top block 522;

[0046] The drive assembly 52 can be used to drive the limiting frame 514 in the vertical direction.

[0047] The working principle and use process of the present invention:

[0048] When it is necessary to automatically sort and stack the bundled printed materials, the staff first controls the adaptive adsorption mechanism 4 to move to the top of the front end of the conveying mechanism 2 through the mechanical handling arm 3, and the sorting scanning device 412 inside the adaptive adsorption mechanism 4 can scan the two-dimensional code on the bundled printed materials at the front end of the conveying mechanism 2. The sorting scanning device 412 will identify the type of the bundled printed materials and the area size of the upper surface of the bundled printed materials. The bundled printed materials can be transported to the corresponding position of the sorting mechanism 5 according to the identified type of the bundled printed materials, and the positions of the four electrically controlled suction cups 429 can be adjusted according to the identified area size of the upper surface of the bundled printed materials, so that the adaptive adsorption mechanism 4 can better adsorb the bundled printed materials. When the bottom of the adaptive adsorption mechanism 4 adsorbs the bundled printed materials, When it is necessary to stack the bundles of printed materials, the control switch of the multi-stage electric telescopic rod 523 is started, and the multi-stage electric telescopic rod 523 can be extended, so that the limit frame 514 moves vertically upward. When the limit frame 514 moves to the vicinity of the middle position of the first layer of bundles of printed materials, the multi-stage electric telescopic rod 523 is closed. At this time, the bundles of printed materials are stacked in sequence above the pad plate 513. The first layer of bundles of printed materials can be limited by the limit frame 514 to make their stacking more neat. After the first layer of bundles of printed materials is stacked, the multi-stage electric telescopic rod 523 is started again to make the limit frame 514 located near the middle position of the second layer of bundles of printed materials. Then, the second layer of bundles of printed materials is started to be stacked, and so on, the third, fourth and fifth layers are stacked until the final stacking is completed.
