Description

Technical Field

[0001] This invention relates to the field of automated palletizing technology, and more specifically to a plywood interlayer palletizing machine. Background Technology

[0002] After plywood is formed, in order to ensure uniform drying, release internal stress, and prevent the plywood from warping, molding, and cracking due to moisture, the industry generally requires layered stacking and ventilation drying of the formed plywood. Currently, existing plywood stacking operations mainly rely on specialized stacking machines to complete the stacking of the plywood. During the operation, spacers need to be laid between every two layers of plywood to create ventilation gaps between the layers to meet the requirements of the plywood drying process.

[0003] Currently, the placement of spacer strips is entirely manual. After the palletizer stacks a single plywood panel, manual intervention is required to place the spacer strips before stacking the next layer of panels. This process is cumbersome and involves a large amount of manual labor. Moreover, the accuracy of manual placement is inconsistent, easily leading to problems such as spacer strip misalignment, misalignment, and uneven spacing, resulting in poor stacking neatness. In addition, the resulting stacks are generally loose, requiring subsequent handling and transportation processes to re-stack and re-ply, impacting the overall operational efficiency of the automated plywood production line. Summary of the Invention

[0004] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a plywood interlayer palletizing machine. This invention integrates a pad placement and retraction assembly for placing pads into the palletizing machine, thereby achieving automated plywood palletizing while ensuring the structural strength of the pallet.

[0005] This invention adopts the following technical solution: a plywood interlayer palletizing machine, comprising:

[0006] The substrate has a connector on the upper side for connecting a robotic arm and a suction cup assembly for adsorbing the substrate on the lower side. Two transverse sliding beams are respectively slidably mounted on the base plate; Each of the transverse sliding beams has two symmetrically arranged longitudinal sliding beams that are slidably mounted on it; and a pad storage assembly is fixed to the end of each longitudinal sliding beam away from the substrate. The pad block placement and placement assembly includes a vertically arranged guide plate, on which pad blocks that can slide vertically are stacked; the pad blocks are used to support the plates to be stacked, and adjacent pad blocks are vertically inserted and connected. The guide plate is provided with a locking mechanism for locking and releasing the pad; After the suction cup assembly picks up the board, the pad placement assembly moves to the four corners of the board and supports the bottom pad at the four corners of the board.

[0007] Furthermore, the guide plate in the pad block receiving and discharging assembly is L-shaped, and a guide strip is fixed to the side of the inner wall of the guide plate; The L-shaped pad is attached to the inner wall of the guide plate, and the end faces of both sides of the main body are provided with sliding grooves that slide with the guide strip.

[0008] The upper surface of the main body is provided with multiple slots, and the lower surface of the main body is fixed with a plug block that mates with the slots of the lower main body. The inner wall of the main body is fixed with support blocks for supporting the plates; The outer side of the main body has multiple threaded holes.

[0009] A locking groove is provided at the corner of the outer wall of the main body; A guide groove is provided at the corner of the lower end of the guide plate, which is opposite to the locking groove and passes through the guide plate. The locking mechanism includes a locking block slidably mounted in the guide groove, and a locking cylinder for driving the locking block to extend into or disengage from the locking groove. When the locking cylinder drives the locking block to extend into the locking groove, the locking block is partially located in the guide groove; When the locking cylinder drives the locking block to disengage from the locking groove, the locking block is located in the guide groove.

[0010] The locking cylinder is fixedly connected to the locking block via an elastic rod.

[0011] The two longitudinal sliding beams on each of the transverse sliding beams are driven synchronously by a longitudinal drive mechanism; The opposite ends of the two longitudinal sliding beams are staggered in an "L" shape, and the opposite ends of the longitudinal sliding beams include a short side and a long side; The longitudinal drive mechanism includes a pair of longitudinal slide rails fixed on the transverse sliding beam, and the longitudinal sliding beam is slidably mounted on the longitudinal slide rails by a slider; Among them, racks are fixed on the opposite faces of the long sides of the two longitudinal sliding beams, and drive gears are simultaneously meshed between the two racks. The drive gears are connected to the output shaft of the longitudinal drive motor.

[0012] A guide rod parallel to the longitudinal slide rail is fixed on the short side of the longitudinal sliding beam, and a guide hole that slides with the guide rod is opened on the long side of the other longitudinal sliding beam.

[0013] The lateral drive mechanism includes a pair of lateral slide rails fixed on the base plate, and a lateral sliding beam is slidably mounted on the lateral slide rails via a slider; A bidirectional lead screw is rotatably mounted on the base plate between the two transverse slide rails. Nuts connected to both ends of the bidirectional lead screw are fixedly connected to the transverse sliding beam on the corresponding side. A transverse drive motor is fixedly connected to one end of the bidirectional lead screw.

[0014] The substrate has evenly distributed connection holes, and multiple suction cup assemblies are fixed to the lower side of the substrate through the connection holes; multiple wire grooves are formed on the substrate.

[0015] The beneficial effects of this invention are as follows: During the stacking of plywood, the pad blocks are automatically released and locked simultaneously, realizing full automation of the plywood interlayer stacking and destacking process, reducing manual intervention, solving the problems of high labor intensity and inconvenience of manual pad placement and stacking and destacking operations, and improving the overall stacking efficiency. By adjusting the position of the four sets of pad block take-up and take-up components through the horizontal and vertical drive mechanisms, it can adapt to the stacking operation of plywood of various length and width specifications. The pads are inserted and spliced ​​together, and the pads are stacked to form a vertical whole. The outer side of the pads has threaded holes. After the stacking is completed, multiple rows of pads can be tied together and fixed by connecting rods to bind the entire stack of plywood into one piece, which improves the stability of the stack. After the stacking is completed, subsequent transportation and insertion operations can be carried out directly, avoiding secondary disassembly and assembly. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0030] Example 1: like Figures 1 to 5As shown, this invention provides a plywood palletizing machine for automated plywood palletizing operations. The palletizing machine mainly includes a base plate 1, a suction cup assembly 2, a transverse sliding beam 3, a longitudinal sliding beam 5, and a pad placement and collection assembly 7. The base plate 1 is rectangular and has evenly distributed connection holes 101 on it. A connecting seat 11 is fixedly installed at the center of the upper side of the base plate 1 through the connection holes 101. The upper end of the connecting seat 11 has a pre-drilled standard robotic arm docking flange hole, which can be directly fixedly connected to the end of an industrial robotic arm. The robotic arm drives the entire base plate 1 to complete overall actions such as lifting, translation, and alignment.

[0031] Several sets of suction cup assemblies 2 are evenly fixed to the underside of the substrate 1 through connecting holes 101. The suction cup assemblies 2 adopt a vacuum suction cup structure for negative pressure adsorption and fixing of plywood sheets to be stacked. The number of suction cups and the installation position of suction cups can be flexibly increased or decreased according to the specifications of the sheets. The substrate 1 is also provided with multiple neatly arranged cable trays 102 for storing equipment cables. The suction cup assembly 2 is prior art and will not be described in detail in this embodiment.

[0032] Two transverse sliding beams 3 are symmetrically slidably mounted on the upper side of the substrate 1. These beams are driven by a transverse drive mechanism 4, causing them to slide synchronously towards or away from each other along the transverse direction of the substrate 1. Each transverse sliding beam 3 has two symmetrically arranged longitudinal sliding beams 5 slidably mounted on it. These beams are driven by a longitudinal drive mechanism 6, causing them to slide synchronously towards or away from each other along the longitudinal direction. A set of pad placement and retraction components 7 is fixedly mounted at the end of each longitudinal sliding beam 5 furthest from the substrate 1. The four sets of pad placement and retraction components 7 are arranged in a rectangular quadrant, corresponding to the four corners of the plywood sheet. The position of the pad placement and retraction components 7 can be controlled by adjusting the movement of the transverse sliding beams 3 and the longitudinal sliding beams 5.

[0033] Combined Figures 8 to 10 As shown, the pad block storage and unfolding assembly 7 is used to realize the storage, locking, release, and supporting stacking of interlayer pad blocks. The pad block storage and unfolding assembly 7 includes a vertically arranged guide plate 71 fixed to the end of the longitudinal sliding beam 5. The guide plate 71 has an "L" shaped cross-section, and long strip-shaped guide pressure strips 72 are fixedly installed on both sides of the inner side wall of the guide plate 71. Multiple pad blocks 9 that can slide freely vertically are vertically stacked inside the guide plate 71. The pad blocks 9 are connected sequentially by a vertical insertion method to achieve stacked storage. A locking mechanism 8 is installed on the guide plate 71 to lock and release the stacked pad blocks 9.

[0034] In this embodiment, the main body 91 of the pad 9 is also L-shaped, which can completely fit the inner wall of the guide plate 71. Sliding grooves 911 are provided on both ends of the main body 91. The sliding grooves 911 and guide strips 72 slide in a one-to-one correspondence, allowing the stacked pads 9 to slide smoothly vertically along the guide strips 72, achieving vertical stacking and smooth falling of the pads 9. A rectangular slot 912 is provided on each side of the upper end face of the main body 91. A matching insert 92 is fixed on the lower end face of the main body 91 corresponding to the slot 912. Two adjacent pads 9 are vertically joined by the insertion of the insert 92 into the slot 912, forming a single structure. A protruding support block 93 is fixedly provided on the inner side wall of the main body 91. The support block 93 is made of a hard, wear-resistant material, and its upper surface is a flat support surface used to directly contact and support the edges and corners of the plywood. Multiple threaded holes 913 are evenly provided on the outer side of the main body 91. After the stacking is completed, the same or different columns can be connected by connecting rods to improve the stability of the entire stacking and make the stacking ready for direct transportation.

[0035] During homework; The suction cup assembly 2 at the bottom of the substrate 1 vacuum picks up a single piece of plywood. Then, through the linkage adjustment of the transverse sliding beam 3 and the longitudinal sliding beam 5, the four sets of pad block take-up and put-down assemblies 7 are moved to the four corners of the board, and the support block 93 of the bottom pad block 9 is located below the corner of the board. After the substrate 1 is moved to the predetermined position, the suction cup assembly 2 releases the substrate, and the locking mechanism 8 releases the bottom pad 9, so that the pad 9 is accurately supported on the stacking base or the previously released pad 9; control the substrate 1 to be lifted, and at the same time the locking mechanism 8 relocks the next pad 9. Repeat the above steps to achieve interlayer stacking of the boards; the final structure is as follows. Figure 11 As shown; In addition, the palletizer can also automatically depalletize, and the operation is the reverse of the above process, which will not be described in detail in this embodiment.

[0036] In another embodiment, the suction cup assembly 2 adopts a floating structure, that is, the suction cup assembly 2 can swing freely at a small angle; in this way, when the four sets of pad placement and retraction assemblies 7 move to the four corners of the board, they can automatically clamp the board and achieve precise positioning of the board; in this process, the floating suction cup assembly 2 can avoid hard interference with the four sets of pad placement and retraction assemblies 7, which would affect the adsorption effect of the suction cup assembly 2.

[0037] The plywood interlayer stacking machine disclosed in this embodiment can automatically and accurately place interlayer pads during the board stacking process, realize layered and isolated stacking of boards, replace manual pad placement, and effectively improve the neatness and work efficiency of plywood stacking; at the same time, the overall stacking has good stability and can be directly used for subsequent insertion and transportation.

[0038] Example 2: Based on the above embodiment one, combined with Figures 8 to 10 As shown, this embodiment provides a locking mechanism 8; A rectangular locking groove 914 is provided at the corner of the outer wall of the pad block body 91, and a guide groove 711 that penetrates the plate body is provided at the lower corner of the guide plate 71. The guide groove 711 is horizontally aligned with the locking groove 914 of the bottom pad block. The main body 91 of the locking mechanism 8 includes a locking block 81 and a locking cylinder 83. The locking block 81 is slidably installed inside the guide groove 711 and can slide horizontally back and forth along the guide groove 711. The locking cylinder 83 is fixed to the outer wall of the guide plate 71 by a cylinder bracket. The telescopic end of the locking cylinder 83 is fixedly connected to an elastic rod 82, and the other end of the elastic rod 82 is fixedly connected to the locking block 81. In this embodiment, the elastic rod 82 adopts a spring buffer structure, which is used to buffer the impact force during the locking telescopic process and to prevent damage to the locking mechanism 8 caused by the locking cylinder 83 forcibly locking when the guide groove 711 and the locking groove 914 are not aligned.

[0039] During operation, the pads are pre-stacked inside the guide plate 71; When in standby mode, the locking cylinder 83 retracts and pushes the locking block 81 to slide inward along the guide groove 711 via the elastic rod 82. The end of the locking block 81 extends into the locking groove 914 of the pad, and the remaining part of the locking block 81 remains in the guide groove 711. Through the limiting engagement of the locking block 81, all the stacked pads are locked inside the guide plate 71 to prevent the pads from sliding off freely. When a pad needs to be placed, the locking cylinder 83 extends, causing the elastic rod 82 and the locking block 81 to slide outward as a whole, so that the locking block 81 completely disengages from the locking groove 914 and is fully stored inside the guide groove 711, releasing the limiting lock on the pad; at this time, the pad loses the limiting constraint and slides vertically down the guide strip 72 under the action of gravity, disengaging from the guide plate 71 and accurately supporting itself on the stacking base or the previously released pad; After placement, the upper pad automatically falls to fill the gap, waiting for the next locking and releasing operation, thus achieving continuous palletizing operation in a cycle.

[0040] Example 3: Based on the above embodiments one or two, combined with Figures 1 to 5As shown, in this embodiment, the lateral drive mechanism 4 includes a lateral slide rail 41, a bidirectional lead screw 42, a lateral drive motor 43, and a matching nut assembly. A pair of parallel lateral slide rails 41 are fixedly mounted on the upper side of the base plate 1. The two lateral slide rails 41 are symmetrically distributed on both sides of the central axis of the base plate 1. The lower part of the lateral sliding beam 3 slides against the lateral slide rails 41 via a slider. A bidirectional lead screw 42 is parallel to the two lateral slide rails 41. Both ends of the bidirectional lead screw 42 are rotatably mounted on the base plate 1 via bearing seats. The positive and negative thread sections of the bidirectional lead screw 42 are respectively connected to a nut seat, and the nut seat is fixed to the corresponding side of the lateral sliding beam 3. One end of the bidirectional lead screw 42 passes through the bearing seat and is fixedly connected to the output shaft of the lateral drive motor 43. The lateral drive motor 43 is fixed to one end of the base plate 1 via a motor bracket.

[0041] During operation, the transverse drive motor 43 rotates in the forward direction, driving the bidirectional lead screw 42 to rotate synchronously. The nut seats at both ends of the lead screw move towards each other, driving the two transverse sliding beams 3 to move closer to each other synchronously along the transverse slide rail 41. When the transverse drive motor 43 rotates in the reverse direction, the two transverse sliding beams 3 move further away from each other synchronously, thereby realizing stepless adjustment of the transverse spacing to adapt to plywood boards of different widths.

[0042] Combined Figure 6 and Figure 7 As shown, in this embodiment, the longitudinal drive mechanism 6 includes a pair of longitudinal slide rails 61 fixed to the upper side of the transverse sliding beam 3. The longitudinal sliding beam 5 slides smoothly longitudinally by sliding with the longitudinal slide rails 61 through a slider. The two longitudinal sliding beams 5 on the same transverse sliding beam 3 are both set with staggered L-shaped structures at their opposite ends. The L-shaped structure is divided into a short side 51 and a long side 52. The long side 52 and the short side 51 of the two sets of longitudinal sliding beams 5 are opposite to each other to avoid structural interference during sliding. A rack 62 is fixedly installed on the opposite surface of the long side 52 of the two longitudinal sliding beams 5. The two racks 62 are arranged in parallel and symmetrically, and a drive gear 63 is simultaneously meshed between the two racks 62. The central shaft of the drive gear 63 is fixedly connected to the output shaft of the longitudinal drive motor 64. The longitudinal drive motor 64 is fixed at the center position of the transverse sliding beam 3 by a motor bracket.

[0043] To further improve sliding stability, a guide rod 65 parallel to the longitudinal slide rail 61 is fixedly installed on the short side 51 of the longitudinal sliding beam 5. A guide hole is opened on the long side 52 of the opposite longitudinal sliding beam 5. The guide rod 65 slides through the guide hole. Through the limiting cooperation between the guide rod 65 and the guide hole, the stability of the longitudinal sliding beam 5 when sliding outward to the limit position is improved, avoiding the shaking and offset problems of the longitudinal sliding beam 5 during the sliding process, and ensuring the alignment accuracy of the four corner pads.

[0044] During operation, the longitudinal drive motor 64 drives the drive gear 63 to rotate. The two sides of the drive gear 63 mesh synchronously, causing the two racks 62 to move in opposite directions in a straight line. This drives the two longitudinal sliding beams 5 to slide synchronously towards or away from each other along the longitudinal slide rail 61, achieving precise adjustment of the longitudinal spacing and adapting to plywood boards of different lengths.

[0045] Palletizer operation process S1. Equipment debugging: According to the length and width specifications of the plywood to be stacked, start the horizontal drive motor 43 and the vertical drive motor 64, and adjust the spacing of the two horizontal sliding beams 3 and the four sets of vertical sliding beams 5 so that the positions of the four sets of pad block placement and removal components 7 are aligned with the four corners of the board. S2, Board Pickup: The robotic arm moves the whole machine to the loading station and uses the suction cup assembly 2 at the bottom of the substrate 1 to adsorb and fix a single piece of plywood board. S3, Pad alignment: Keep the board in an adsorbed and fixed state, and adjust the position of the pad take-up and put-down assembly 7 through the horizontal drive mechanism 4 and the vertical drive mechanism 6 to ensure that the four sets of pad take-up and put-down assemblies 7 are accurately aligned with the four corners of the board. S4, Pad Release: Locking cylinder 83 retracts, unlocking locking mechanism 8, and the bottom pad 9 falls and is supported at the four corners of the plate. S5. Stacking: The robotic arm moves the board and bottom pad 9 to the stacking station, and the board is placed down to complete the single-layer stacking. The pad 9 is left at the bottom of the board to form a gap between the layers. Repeating the above steps can complete the automated layer stacking operation of multi-layer plywood.
