Description

Technical Field

[0001] This invention belongs to the field of material flipping and rotating technology, and specifically relates to an automatic pallet blocking and release device. Background Technology

[0002] A flipping machine is a device that can automatically flip material pallets. It mainly consists of a drive motor, a flipping frame, a turntable, and a chain. When the pallet is picked up by the robotic arm and placed on the flipping frame, the motor drives the flipping frame to rotate through the chain, which flips the material pallet that was originally placed horizontally on the flipping frame to a vertical position.

[0003] In the existing technology, the flipping machine does not have any blocking or limiting structure designed on it. As a result, the receiving pallet may tip over after being placed on the flipping frame. Furthermore, the receiving pallet is also prone to tipping over during the subsequent flipping process, which reduces the automation level of the entire production line. To address this, the present invention proposes an automatic pallet blocking and release device. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic pallet blocking and release device to solve the problems mentioned in the background art.

[0022] 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.

[0023] Example

[0024] Please see Figures 1 to 6 This embodiment of the invention provides a technical solution: an automatic pallet blocking and releasing device, comprising...

[0025] Frame 1, a rotating frame 2 rotatably mounted on the top of frame 1, a rotating disk 7 welded and fixed to one side surface of rotating frame 2, a chain 6 mounted on the surface of rotating disk 7, and a drive assembly 3 set inside frame 1 and connected to chain 6.

[0026] The gripper assembly 5, located at the bottom left side of the flipping frame 2, includes a base plate 51 fixed to the bottom surface of the flipping frame 2 by bolts, a guide sleeve 52 welded to the bottom surface of the base plate 51, a rack 53 that movably passes through the guide sleeve 52, a gripper gear 55 rotatably mounted on the bottom of the base plate 51 and meshing with the rack 53, a gripper plate 56 fixed to the gripper gear 55, and a spring A54 located on the bottom surface of the rack 53. A crossbeam 11 corresponding to the rack 53 is welded to the inner side of the frame 1.

[0027] Among them, a roller 57 is installed at the bottom end of the rack 53, and the spring A54 is located between the roller 57 and the guide sleeve 52.

[0028] The top of the rack 53 extends through to the top of the substrate 51 and is welded to a non-detachment block, so that the rack 53 will not be directly separated from the substrate 51 or the guide sleeve 52.

[0029] The gripper gear 55 is welded and fixed together with the gripper plate 56, and an arc-shaped notch is provided on one side surface of the guide sleeve 52 for the gripper gear 55 to rotate.

[0030] The gripper plate 56 has an anti-slip pad 58 installed on its inner top surface. The top surface of the anti-slip pad 58 has an integrated insert block 581. The top surface of the gripper plate 56 has a slot 561 for inserting the insert block 581. A disassembly / assembly structure 59 is provided between the gripper plate 56 and the insert block 581. The disassembly / assembly structure 59 includes a movable locking block 592 extending through the top of the gripper plate 56 and a limiting slot 593 on the surface of the insert block 581. One end of the movable locking block 592 is inserted into the limiting slot 593 to stably limit the insertion block 581 and the anti-slip pad 58. The other end of the movable locking block 592 extends through to the side of the gripper plate 56 and is fixed with a movable plate 591. The side of the gripper plate 56 has a side hole communicating with the slot 561, and the side hole corresponds to the movable locking block 592 for the movable plate to be inserted. With the smooth penetration of block 592, an upper sliding groove 594 is provided on the upper wall of the side hole. The upper sliding groove 594 is equipped with a spring B595 and an upper slider 596. The bottom end of the upper slider 596 is fixed to the movable locking block 592. Under the pushing action of the spring B595, the end of the movable locking block 592 can be stably inserted into the limiting groove 593 during daily use, so as to stably limit the anti-slip pad 58. If the anti-slip pad 58 needs to be removed for replacement, simply pull the movable plate 591 to the side, so that the upper slider 596 moves to the side and compresses the spring B595 until the end of the movable locking block 592 moves out of the limiting groove 593, thereby releasing the limitation on the insertion block 581. At this time, the anti-slip pad 58 can be moved down and directly separated from the gripper plate 56, which is convenient for the operator to disassemble and replace the anti-slip pad 58.

[0031] Among them, a chain fixing plate 71 is welded and fixed on the surface of the rotating disk 7, and a chain joint 72 is provided at both ends of the chain fixing plate 71. The two ends of the chain 6 are respectively fixed on the two chain joints 72. Both sides of the flipping frame 2 are rotatably connected to the frame 1 through a support shaft 4, so as to realize the smooth rotation and installation of the flipping frame 2.

[0032] The drive assembly 3 includes a motor 31 fixed inside the frame 1. A drive gear 32 that meshes with the chain 6 is installed on the output end of the motor 31. After the motor 31 is started, the chain 6 can be driven to rotate the rotating disk 7 and the tilting frame 2 through the drive gear 32.

[0033] In summary, during actual operation, in the initial state, the bottom surface of the tilting frame 2 is parallel to the top surface of the frame 1. At this time, the roller 57 at the bottom of the rack 53 disengages from the crossbeam 11, causing the rack 53 to be pushed upwards and rotate with the gripper gear 55. This causes the gripper plate 56 to move laterally and open, allowing the receiving tray to be placed smoothly. When the robot places the receiving tray on the tilting frame 2, the drive assembly 3 starts to drive the tilting frame 2 to rotate to the right, so that the roller 57 is no longer in contact with the crossbeam 11. Under the pushing action of the spring A54, the rack 53 moves downwards and resets, driving the gripper gear 55 and the gripper plate 56 to rotate. Finally, the gripper plate 56 can clamp onto one side of the receiving tray, and the anti-slip pad 58 is tightly pressed against the top surface of the receiving tray. The tight fit acts as a blocking and limiting mechanism to prevent the receiving tray from tipping over or tilting during the flipping process. When the flipping frame 2 rotates 90 degrees, the blocking and pressing of the gripper assembly 5 prevents the receiving tray from tipping over and affecting subsequent normal material receiving. After the flipped receiving tray has finished receiving the material, the drive assembly 3 drives the flipping frame 2 to flip back, causing the flipping frame 2 to flip and reset with the receiving tray. Finally, the roller 57 rests on the crossbeam 11 again, and the gripper plate 56 rotates sideways to automatically open and allow passage. When the flipping frame 2 flips back 90 degrees, the gripper plate 56 is fully open, and you can wait for the receiving tray to leave. After the tray leaves, you can wait for the next tray to come in and repeat the above steps.

[0034] Although embodiments of the invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
