Description

Technical Field

[0001] This invention relates to the field of stacking equipment technology, specifically to a cargo stacking equipment for logistics transportation. Background Technology

[0002] In the logistics warehousing and transportation industry, cargo stacking equipment is a core component for improving space utilization and achieving automated operations. Common cargo stacking equipment includes pallet stackers, empty pallet stackers, high-bay stackers, and robotic palletizing systems. Among these, empty pallet stackers or some heavy-duty pallet stackers typically employ an "upward insertion" stacking method.

[0003] During stacking operations, as operators insert goods into an existing stack using a lifting mechanism, the instantaneous vibrations generated by the lifting action are transmitted throughout the entire stack. Because this vibrational energy is transmitted and amplified layer by layer upwards within the stack, goods at the top are highly susceptible to slight slippage or displacement due to force imbalance. When further stacking occurs, the already displaced top goods cannot be effectively restrained by the goods below. Under the combined effect of gravity and further vibration, they may slip off the stack edge or even fall completely out of the stack, causing damage to the outer shell, displacement of internal fillers, or impact damage to precision components, thus affecting the integrity of the goods and transportation safety. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a cargo stacking device for logistics transportation, including a frame, lifting grippers slidably connected to the inner wall of the frame, lifting grippers slidably connected to the outer wall of the sliding frame, a conveyor belt disposed on the inner wall of the frame, and further comprising:

[0005] A fixing mechanism is installed on the outer wall of the frame, and the fixing mechanism includes a connecting rod.

[0006] A sliding mechanism is installed on the outer wall of the fixed mechanism, and the sliding mechanism includes a connecting plate;

[0007] A contact mechanism is installed on the outer wall of the fixed mechanism, and the contact mechanism includes a fixing ring.

[0008] When the material reaches the space between the two lifting grippers via the conveyor belt, the operator starts the motor to slide the sliding frame to the designated position and pushes the lifting grippers to insert them into the bottom of the goods.

[0009] Preferably, the fixing mechanism further includes:

[0010] The connecting components are installed on the outer wall of the frame.

[0011] A flip component is installed on the outer wall of the connecting component.

[0012] As goods are continuously stacked, they will slide along the outer wall of the connecting components.

[0013] Preferably, the sliding mechanism further includes:

[0014] A sliding component is installed on the outer wall of the flip component;

[0015] Motion component, the motion component is installed on the outer wall of the motion component;

[0016] When the sliding frame moves upward with the goods, it comes into contact with the flipping component, which then begins to rotate.

[0017] Preferably, the contact mechanism further includes:

[0018] Contact component, the contact component is installed on the outer wall of the connecting component;

[0019] The pusher component is installed on the outer wall of the connecting component;

[0020] As the goods are stacked, they come into contact with the pusher component, causing the pusher component to rotate.

[0021] Preferably, the connecting assembly includes a fixed rod that is fixedly connected to one end of the four connecting rods away from the frame, and the ends of the four connecting rods away from the fixed rod are fixedly connected to the outer wall of the frame;

[0022] As the height of the stacked goods increases, the goods will slide along the outer wall of the fixed rod.

[0023] Preferably, the flipping assembly includes a fixed frame fixedly connected to four fixed rods near the bottom, a flipping plate rotatably connected to both sides of the fixed frame, and limit plates fixedly connected to both sides of the fixed frame;

[0024] The limiting plate restricts the flipping plate one, so that the flipping plate one can only rotate in one direction. In the initial state, the limiting plate and the flipping plate one are in contact with each other.

[0025] Preferably, the sliding assembly includes a second flip plate rotatably connected to the end of the connecting plate away from the fixed frame, and the outer wall of the connecting plate is fixedly connected to the end of the first flip plate near the fixed frame.

[0026] When the first flip plate rotates, it pushes the second flip plate downward, causing the moving components to slide.

[0027] Preferably, the motion component includes two sliding rods slidably connected to the outer walls of both sides of the fixed frame, a fixed plate fixedly connected to the outer wall of the sliding rods, a tension spring fixedly connected to the outer wall of the fixed frame, the end of the tension spring away from the fixed frame being fixedly connected to the inner wall of the sliding rods, and a plurality of pressure blocks fixedly connected to the outer wall of the sliding rods.

[0028] When the flip plate rotates, the sliding rod will slide downwards, at which point the tension spring will be stretched and accumulate potential energy.

[0029] Preferably, the contact assembly includes a rotating bar rotatably connected to the inner wall of a plurality of fixed rings, the ends of the plurality of fixed rings away from the rotating bar being fixedly connected to the outer wall of a fixed rod, a rolling column being rotatably connected to the end of the rotating bar away from the fixed rings, a plurality of elastic strips being fixedly connected to the inner wall of the rolling column, a blocking pawl being rotatably connected to the end of the rolling column away from the rotating bar, and the end of the elastic strips away from the rolling column being fixedly connected to the outer wall of the blocking pawl.

[0030] The elastic strip has an arc-shaped notch at the end away from the rotating strip. When the elastic strip is squeezed by the goods, it will contract towards the rolling column and accumulate elastic potential energy. The contracted elastic strip will pull the blocking claw to rotate away from the rotating strip.

[0031] Preferably, the pushing component includes several rotating plates rotatably connected to the outer wall of the fixed rod. The end of the rotating plate away from the fixed rod is slidably connected to the arc plate. A rotating block is rotatably connected to the inner wall of the arc plate. A spring is fixedly connected to the outer wall of the rotating block. The end of the spring away from the rotating block is fixedly connected to the inner wall of the rotating plate. A square slot is provided on the outer wall of the rotating plate.

[0032] When the goods press against the rotating plate, the plate will rotate, which will push the rolling column to rotate away from the frame.

[0033] The present invention has the following beneficial effects:

[0034] (1) By setting a fixing ring, the goods are stacked upwards, and the goods at the bottom are lifted by the sliding frame. When the goods at the top start to slide, they will contact the elastic strip and cause the elastic strip to contract in the direction of the rolling column. This will cause the blocking claw to be stretched by the elastic strip and rotate in the direction away from the rolling column. At this time, the sliding goods will be restricted by the fixing ring. In this way, the inertial vibration generated by the sliding frame at the moment of lifting is prevented from causing the goods to slip and causing the goods at the top to fall directly when the sliding frame lifts the goods later.

[0035] (2) By setting a sliding rod, when the sliding frame is lifted, the goods will come into contact with the first flipping plate, causing the first flipping plate to rotate. The rotation of the first flipping plate will cause the second flipping plate to press against the fixed plate, thereby causing the sliding rod to slide downward. The sliding rod will cause the pressure block to press against the arc plate. At this time, the arc plate will start to push the rolling column closer to the goods, so that multiple rolling columns will press against the goods, pushing the displaced goods back to their original position. In this way, the multiple movements of the sliding frame will be prevented from causing the distance of the goods displacement to increase continuously, eventually breaking through the restriction of the blocking claw and causing the goods to fall.

[0036] (3) By setting up rolling columns, when the sliding frame lifts the goods, the rolling columns clamping the goods on both sides will be subjected to the lifting force of the sliding frame on the goods. As a result, the rolling columns will also start to rotate during the process of the goods rising. In this way, the resistance of the goods being clamped by the rolling columns when they rise is reduced, and the clamping force of the rolling columns on the goods is prevented from being too large during the process of the goods rising, which would cause the blocking claws to tear the packaging box of the goods.

[0037] (4) By setting multiple fixing rings, when the goods fall, the sideways sliding goods will contact multiple blocking claws. This will restrict the originally tilted sliding goods by the blocking claws on the multiple fixing rings. Since the sliding goods will contact the elastic strip, the goods and the surface of the elastic strip will form a large friction. In this way, when the goods fall, they will be restricted by multiple blocking claws. Even if they slip, the elastic strip will rub against the surface of the goods, reducing the falling speed of the goods and preventing the goods from falling too fast, which would cause damage to the inside of the goods.

[0050] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Example 1, please refer to Figures 1-6 This invention relates to a cargo stacking device for logistics transportation, comprising a frame 12, lifting grippers 15 slidably connected to the inner wall of the frame 12, lifting grippers 15 slidably connected to the outer wall of a sliding frame 14, a conveyor belt 13 disposed on the inner wall of the frame 12, and further comprising:

[0052] Fixing mechanism 2 is installed on the outer wall of frame 12, and fixing mechanism 2 includes connecting rod 211;

[0053] Sliding mechanism 3 is installed on the outer wall of fixed mechanism 2, and sliding mechanism 3 includes connecting plate 311;

[0054] Contact mechanism 4 is installed on the outer wall of fixed mechanism 2, and contact mechanism 4 includes fixed ring 411;

[0055] When the material reaches the space between the two lifting grippers 15 via the conveyor belt, the operator starts the motor to slide the sliding frame 14 to the designated position and pushes the lifting grippers 15 to insert them into the bottom of the goods.

[0056] Fixed mechanism 2 also includes:

[0057] Connecting component 21 is installed on the outer wall of frame 12;

[0058] The flip component 22 is installed on the outer wall of the connecting component 21;

[0059] As the goods are continuously stacked, they will slide on the outer wall of the connecting component 21.

[0060] Example 2, please refer to Figures 2-9 This invention relates to a cargo stacking device for logistics transportation. Based on Embodiment 1, the sliding mechanism 3 further includes:

[0061] Sliding component 31 is installed on the outer wall of flip component 22;

[0062] Motion component 32, motion component 32 is mounted on the outer wall of motion component 32;

[0063] When the sliding frame 14 moves upward with the goods, it comes into contact with the flipping component 22, and the flipping component 22 will start to rotate.

[0064] Contact mechanism 4 also includes:

[0065] Contact component 41 is installed on the outer wall of connecting component 21;

[0066] Push component 42 is installed on the outer wall of connecting component 21;

[0067] As the goods are stacked, they come into contact with the push component 42, causing the push component 42 to rotate.

[0068] The connecting assembly 21 includes a fixed rod 212 fixedly connected to one end of the four connecting rods 211 away from the frame 12, and the ends of the four connecting rods 211 away from the fixed rod 212 are fixedly connected to the outer wall of the frame 12.

[0069] As the height of the stacked goods increases, the goods will slide along the outer wall of the fixed rod 212.

[0070] The flipping assembly 22 includes a fixed frame 221 fixedly connected to four fixed rods 212 near the bottom. A flipping plate 222 is rotatably connected to both sides of the fixed frame 221. A limit plate 223 is fixedly connected to both sides of the fixed frame 221.

[0071] Among them, the limiting plate 223 restricts the flip plate 222, so that the flip plate 222 can only rotate in one direction. In the initial state, the limiting plate 223 and the flip plate 222 are in contact with each other.

[0072] The sliding assembly 31 includes a second flip plate 312 rotatably connected to the end of the connecting plate 311 away from the fixed frame 221, and the outer wall of the connecting plate 311 is fixedly connected to the end of the first flip plate 222 near the fixed frame 221.

[0073] When the first flip plate 222 rotates, it will push the second flip plate 312 downward, causing the motion component 32 to slide.

[0074] The motion component 32 includes two sliding rods 322 that are slidably connected to the outer walls of both sides of the fixed frame 221. A fixed plate 323 is fixedly connected to the outer wall of the sliding rods 322. A tension spring 321 is fixedly connected to the outer wall of the fixed frame 221. One end of the tension spring 321 away from the fixed frame 221 is fixedly connected to the inner wall of the sliding rods 322. Several pressure blocks 324 are fixedly connected to the outer wall of the sliding rods 322.

[0075] When the flip plate 222 rotates, the sliding rod 322 will slide downward, at which time the tension spring 321 will be stretched and accumulate potential energy.

[0076] The contact assembly 41 includes a rotating bar 412 rotatably connected to the inner wall of a plurality of fixed rings 411. The ends of the fixed rings 411 away from the rotating bar 412 are fixedly connected to the outer wall of the fixed rod 212. A rolling column 413 is rotatably connected to the end of the rotating bar 412 away from the fixed rings 411. A plurality of elastic bars 414 are fixedly connected to the inner wall of the rolling column 413. A blocking claw 415 is rotatably connected to the end of the rolling column 413 away from the rotating bar 412. The ends of the elastic bars 414 away from the rolling column 413 are fixedly connected to the outer wall of the blocking claw 415.

[0077] The elastic strip 414 has an arc-shaped notch at the end away from the rotating strip 412. When the elastic strip 414 is squeezed by the goods, it will contract towards the rolling column 413 and accumulate elastic potential energy. The contracted elastic strip 414 will pull the blocking claw 415 to rotate away from the rotating strip 412. By setting the fixing ring 411, when the goods are stacked upwards, the bottom goods will lift the upper goods through the sliding frame 14. When the top goods start to slide, they will contact the elastic strip 414 and contract towards the rolling column 413. This will stretch the blocking claw 415 by the elastic strip 414 and make the blocking claw 415 rotate away from the rolling column 413. At this time, the sliding goods will be restricted by the fixing ring 411. In this way, the inertial vibration generated by the sliding frame 14 at the moment of lifting will be prevented from causing the goods to slip and causing the goods at the top to fall directly when the sliding frame 14 lifts the goods later.

[0078] The pushing component 42 includes several rotating plates 421 rotatably connected to the outer wall of the fixed rod 212. The end of the rotating plate 421 away from the fixed rod 212 is slidably connected to the arc plate 422. A rotating block 423 is rotatably connected to the inner wall of the arc plate 422. A spring 424 is fixedly connected to the outer wall of the rotating block 423. The end of the spring 424 away from the rotating block 423 is fixedly connected to the inner wall of the rotating plate 421. A square slot 425 is provided on the outer wall of the rotating plate 421.

[0079] When the goods press against the rotating plate 421, the rotating plate 421 will rotate, thereby pushing the rolling column 413 to rotate away from the frame 12. By setting the sliding rod 322, when the sliding frame 14 is lifted, the goods will come into contact with the flipping plate 222, causing the flipping plate 222 to rotate. The rotation of the flipping plate 222 will cause the flipping plate 312 to press against the fixed plate 323, thereby causing the sliding rod 322 to slide downward. The sliding rod 322 will cause the pressure block 324 to press against the arc plate 422. At this time, the arc plate 422 will start to push the rolling column 413 closer to the goods, so that multiple rolling columns 413 will press against the goods, pushing the displaced goods back to their original position. In this way, the repeated movement of the sliding frame 14 will prevent the distance of the goods displacement from continuously increasing, eventually breaking through the restriction of the blocking claw 415 and causing the goods to fall.

[0080] A specific application of this embodiment is as follows: At the start of work, the operator places the goods on the external conveyor belt. The operator starts the motor, causing the conveyor belt 13 to rotate. The goods are then transported between the two lifting grippers 15. The operator then closes the conveyor belt 13 and controls the sliding frame 14 to slide, causing the lifting grippers 15 to reach the designated position. The operator controls the lifting grippers 15 to insert them into the bottom of the goods. When the lifting grippers 15 are fully inserted, the operator starts the motor on the sliding frame 14, causing it to slide upwards. As the goods rise, they contact the bottom of the tilting plate 222, causing the tilting plate 222 to rotate. At this time, the torsion spring inside the tilting plate 222 will... The process begins to accumulate potential energy. When the goods rotate the tilting plate 222 to the same plane as the fixed rod 212, the torsion spring inside the tilting plate 222 releases its elastic potential energy, restoring the tilting plate 222 to a horizontal state. At this time, the sliding frame 14 slides downward again, and the goods are placed on the tilting plate 222. After placement, the operator transports the next goods via the conveyor belt 13 to the middle of the two lifting grippers 15. The operation is repeated again, with the lifting grippers 15 holding the goods and the sliding frame 14 moving upward. During the upward movement, it will contact the tilting plate 222 again, causing the tilting plate 222 to rotate. The goods that were originally on the outer wall of the tilting plate 222 will be lifted up. When the goods are transported upward again, the tilting plate 222 will be rotated. After rotating to the same plane as the fixed rod 212, the torsion spring inside the flip plate 222 will release its potential energy again, causing the originally tilted flip plate 222 to return to a horizontal state. The goods placed for the first time will be lifted up and eventually stacked on top of the goods conveyed for the second time. As the goods are continuously stacked and the height increases, when the sliding frame 14 lifts the stacked goods with the next goods, the goods will contact the rolling column 413. When the stacked goods move upward, they will contact the elastic strip 414. When the elastic strip 414 is pushed by the goods, the rolling column 413 will rotate. When the goods at the top slide during the stacking process, one end of the goods will contact the outer wall of the elastic strip 414, and the elastic strip 414 will roll towards the outer wall. As column 413 contracts internally, the contracted elastic bar 414 pulls the blocking claw 415 away from the rotating bar 412, causing the blocking claw 415 to clamp the sides of the goods. During the upward transport of goods by the sliding frame 14, the goods push the tilting plate 222 to rotate. This rotation causes the connecting plate 311 to move as well. As the connecting plate 311 moves, the tilting plate 312 presses against the fixed plate 323. When the fixed plate 323 begins to move downwards, the sliding rod 322 also moves downwards. At this time, the tension spring 321 is stretched and accumulates potential energy. The downward-moving sliding rod 322 causes the pressure block 324 to press against the arc surface of the arc-shaped plate 422, which causes the rolling column 413 to move closer to the goods.At this point, multiple rolling columns 413 will compress the goods. When the goods are stacked to a specified quantity, the sliding frame 14 can be stopped, completing the stacking process.

[0081] By setting a fixing ring 411, when goods are stacked upwards, the bottom goods are lifted by the sliding frame 14. When the top goods begin to slide, they will contact the elastic strip 414, causing the elastic strip 414 to contract towards the rolling column 413. This will stretch the blocking claw 415 by the elastic strip 414, causing the blocking claw 415 to rotate away from the rolling column 413. At this time, the sliding goods will be restricted by the fixing ring 411. In this way, the inertial vibration generated by the sliding frame 14 at the moment of lifting will be prevented from causing the goods to slip, so that when the sliding frame 14 lifts the goods later, the goods at the top will fall directly.

[0082] By setting the sliding rod 322, when the sliding frame 14 is lifted, the goods will come into contact with the first flip plate 222, causing the first flip plate 222 to rotate. The rotation of the first flip plate 222 will cause the second flip plate 312 to press against the fixed plate 323, thereby causing the sliding rod 322 to slide downward. The sliding rod 322 will cause the pressure block 324 to press against the arc plate 422. At this time, the arc plate 422 will start to push the rolling column 413 closer to the goods, so that multiple rolling columns 413 will press against the goods, pushing the displaced goods back to their original position. In this way, the repeated movement of the sliding frame 14 will prevent the distance of the goods displacement from continuously increasing, eventually breaking through the restriction of the blocking claw 415 and causing the goods to fall.

[0083] By setting the rolling columns 413, when the sliding frame 14 lifts the goods, the rolling columns 413 clamping on both sides of the goods will be subjected to the lifting force of the sliding frame 14 on the goods. As the goods rise, the rolling columns 413 will also start to rotate. In this way, the resistance of the goods being clamped by the rolling columns 413 when the goods rises is reduced, and the clamping force of the rolling columns 413 on the goods is prevented from being too large during the rise, which would cause the blocking claws 415 to tear the packaging box of the goods.

[0084] By setting multiple fixing rings 411, when the goods fall, the sideways sliding goods will contact multiple blocking claws 415. This will restrict the originally tilted sliding goods by the blocking claws 415 on the multiple fixing rings 411. Since the sliding goods will contact the elastic strip 414, the goods and the surface of the elastic strip 414 will form a large friction. In this way, when the goods fall, they will be restricted by multiple blocking claws 415. Even if they slip, the elastic strip 414 will rub against the surface of the goods, reducing the falling speed of the goods and preventing the goods from falling too fast and causing damage to the inside of the goods.
