[0024] In one embodiment of the present utility model, as Figures 1 to 5 shown, a tray automatic stacking machine is provided, which includes a cabinet 1 and a feeding belt 2. The feeding belt 2 extends towards the cabinet 1, so that the end of the feeding belt 2 extends deep into the cabinet 1. A top plate 11, a lifting part 12 and a driving guide rail 13 are arranged in the cabinet 1. The lifting part 12 includes a lifting guide rail 121 and a bracket 122 that moves up and down on the lifting guide rail 121. A base 123 is arranged at the bottom of the lifting guide rail 121, and a discharging belt 124 is arranged on the base 123. Two forks 14 are symmetrically arranged on the bracket 122. A receiving part 141 is arranged at the top of the two forks 14. The distance between the two forks 14 is less than the width of the discharging belt 124, and the extending directions of the two forks 14 are the same as the extending direction of the discharging belt 124. The head end of the top plate 11 is connected to the end of the feeding belt 2. A blanking port 3 that is the same size as the tray is arranged in the middle of the top plate 11. The receiving part 141 is in up-and-down movable cooperation with the blanking port 3. Clamping mechanisms 31 are arranged on both sides of the top plate 11 at the blanking port 3. The clamping mechanism 31 includes a towing guide rail 311 and a driving wheel 312. A clamping block 313 is slidably connected to the towing guide rail 311. The two clamping blocks 313 are used for clamping the tray. The driving wheel 312 is arranged at the head end of the top plate 11 and is drivingly connected to a driving motor 314. The driving guide rail 13 is arranged at the top inside the cabinet 1. A top rod 4 is slidably connected to the driving guide rail 13 and is used for pushing the tray downward below the blanking port 3.
[0025] Further, the clamping block 313 is drivingly connected to a clamping cylinder 33 for pushing the clamping block 313 to move towards the tray. A sliding portion 331 is provided on one side of the clamping cylinder 33 for slidably connecting with the towing guide rail 311. Specifically, in use, the tray is conveyed into the cabinet 1 through the feeding belt 2. At this time, the top surfaces of the two forklift forks 14 are in contact with the bottom of the discharging opening 3. After the feeding belt 2 conveys the tray to the top surface of the top plate 11, it is first caught by the driving wheels 312. At the same time, the driving wheels 312 on both sides of the top plate 11 clamp the two sides of the tray and convey the tray towards the end of the top plate 11. When the tray enters the capture range of the clamping block 313, the clamping block 313 is driven by the clamping cylinder 33 to clamp the two sides of the tray. The sliding portion 331 is driven by the towing guide rail 311 to move towards the end of the top plate 11, and at the same time, the tray is moved towards the end of the top plate 11. After towing the tray to the designated position, the clamping cylinder 33 drives the clamping block 313 to release the clamping on the two sides of the tray.
[0026] Further, a limiting block 332 is provided at the end of the towing guide rail 311 for limiting the sliding stroke of the sliding portion 331. Specifically, in use, the tray is conveyed into the cabinet 1 through the feeding belt 2. At this time, the top surfaces of the two forklift forks 14 are in contact with the bottom of the discharging opening 3. After the feeding belt 2 conveys the tray to the top surface of the top plate 11, it is first caught by the driving wheels 312. At the same time, the driving wheels 312 on both sides of the top plate 11 clamp the two sides of the tray and convey the tray towards the end of the top plate 11. When the tray enters the capture range of the clamping block 313, the clamping block 313 is driven by the clamping cylinder 33 to clamp the two sides of the tray. The sliding portion 331 is driven by the towing guide rail 311 to move towards the end of the top plate 11, and at the same time, the tray is moved towards the end of the top plate 11 until the sliding portion 331 abuts against the limiting block 332. At this time, the two sides of the front end of the tray are clamped by the two driving wheels 312, the two sides of the rear end of the tray are clamped by the two clamping blocks 313, the bottom surface of the tray is in contact with the receiving portion 141 at the top of the two forklift forks 14, and the discharging opening 3 can completely accommodate the tray.
[0027] Further, a limiting frame 34 extends downward from the edge of the discharging opening 3.
[0028] Further, the top of the ejector rod 4 is drivingly connected to a driving cylinder 41. The driving cylinder 41 is provided with a slider 411 slidably connected to the driving guide rail 13. A detection portion 42 is provided at the bottom end of the ejector rod 4.
[0029] Further, the ejector rod 4 includes a fixed part 43 and a movable part 44. The fixed part 43 is connected to the driving cylinder 41. An actuating part 45 is integrally formed at the top of the movable part 44. The actuating part 45 is slidably connected within the fixed part 43. The length of the actuating part 45 is the same as the height of the tray. A limiting part 46 is provided at the top of the actuating part 45. Specifically, when the tray is located above the blanking opening 3, the tray is pushed downward by the ejector rod 4 and dropped onto the receiving part 141 at the top of the two forklift forks 14. When pushing, the driving cylinder 41 is used to push the actuating part 45, and the actuating part 45 drives the movable part 44 to move downward, so that the bottom end of the movable part 44 contacts the tray and pushes the tray downward until the limiting part 46 at the top of the actuating part 45 is in limit cooperation with the fixed part 43 and stops descending. At this time, the tray just breaks away from the clamping of the clamping block 313 and the driving wheel 312, achieving an accurate pushing effect.
[0030] Further, the detection part 42 is an infrared sensor, and the infrared sensor is electrically connected to the lifting guide rail 121. The infrared sensor is used to detect the descending height of the bottom of the ejector rod 4. Specifically, the ejector rod 4 pushes the tray downward. The driving cylinder 41 is used to push the actuating part 45, and the actuating part 45 drives the movable part 44 to move downward, so that the bottom end of the movable part 44 contacts the tray and pushes the tray downward until the limiting part 46 at the top of the actuating part 45 is in limit cooperation with the fixed part 43 and stops descending. At this time, the infrared rays emitted by the infrared sensor are exactly blocked by the inner edge of the blanking opening 3 and reflected into the infrared sensor. The infrared sensor sends a stop signal to the lifting guide rail 121, causing the lifting guide rail 121 to stop descending. At this time, the top surface of the topmost tray is flush with the top surface of the top plate 11, facilitating the stacking of the next tray.
[0031] Working principle: When in use, the pallet is conveyed into the cabinet 1 through the feeding belt 2. At this time, the top surfaces of the two forklift forks 14 are in contact with the bottom of the discharging opening 3. After the feeding belt 2 conveys the pallet to the top surface of the top plate 11, it is first captured by the driving wheels 312. At the same time, the driving wheels 312 on both sides of the top plate 11 clamp the two sides of the pallet and convey the pallet towards the end of the top plate 11. During this process, the front end of the pallet squeezes into the space between the two clamping blocks 313, and under the drive of the towing guide rail 311, the pallet is towed to the end of the top plate 11. Finally, the bottom of the pallet is completely suspended above the discharging opening 3. Then, the pallet is pushed downward by the ejector rod 4 and falls onto the tops of the two forklift forks 14. Then, the two forklift forks 14 are driven to move downward by the lifting guide rail 121 so that the top surface of the pallet is flush with the top surface of the top plate 11. Then, a new pallet is transported onto the top surface of the previous pallet. The pallet located on the top plate 11 is pushed downward by the ejector rod 4, and at the same time, the lifting guide rail 121 moves downward so that the two pallets remain in contact until the top surface of the new pallet is flush with the top surface of the top plate 11, waiting for the input of the next pallet; after multiple pallets are stacked, the pallets are placed on the top of the discharging belt 124 by the descent of the lifting guide rail 121. At this time, the lifting guide rail 121 continues to descend until the top surfaces of the two forklift forks 14 are far away from the bottom surface of the pallet, and then they are transported out by the discharging belt 124, achieving an automated stacking effect.
[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
