Description
Technical Field
[0001] This utility model relates to the field of disc decompression machines, specifically a side-fork type disc decompression machine. Background Technology
[0002] The pallet unpacking machine is used to connect to a pallet conveyor line and can be used for palletizing or unpacking. During palletizing, the conveyor line transports a single pallet to the unpacking machine. The unpacking machine uses a forklift mechanism to lift and stack the pallets above the next input pallet, repeating this action to form a pallet stack, thus completing the palletizing process. During unpacking, the conveyor line transports a single pallet stack to the unpacking machine. The forklift mechanism lifts and stacks the pallets from bottom to top, allowing the bottom pallet to be output individually. This process is repeated to output the pallets one by one, thus completing the unpacking process.
[0003] However, pallets come in various types, some with holes on all four sides and others with holes on only two sides. For pallets with holes on only two sides, it is difficult to apply to existing pallet depalletizing machines with straight forklifts on both sides. This is because when such pallets are picked up by the forks and placed into the conveyor line, the holes are coaxial with the conveyor line. This will cause the direction of the holes to not be directly aligned with the forklift mechanisms on both sides of the depalletizing machine when the pallet is fed to it. As a result, the forklift mechanism cannot pick up the pallet in a straight line. Adding a pallet turning mechanism will increase the overall operating cost of the conveyor system.
[0004] The research objective of this utility model is to design a side-fork type pallet unpacking machine that can pick up pallets from the side, in order to address the problems existing in the above-mentioned prior art. Utility Model Content
[0005] To address the problems existing in the prior art, this utility model provides a side-fork type descrambling machine, which can effectively solve the problems existing in the prior art.
[0006] The technical solution of this utility model is: A side-fork type decompression disc machine, comprising: The frame includes a feeding area for inputting pallets; A side fork mechanism is provided on the side of the feeding area. The side fork mechanism includes a side fork frame, two side forks that are laterally rotatably disposed at both ends of the side fork frame, two linkage rods that are slidably disposed on the side fork frame and laterally rotatably disposed, and two linkage members that are respectively linked to the two side forks and whose length is shorter than the length of the side forks. The proximal ends of the two linkage rods are driven to swing by the side fork driving device, and the distal ends are respectively rotatably connected to the two linkage members. When the proximal ends of the two linkage rods swing toward the feeding area, the distal ends swing outward and push the two linkage members outward, so as to drive the two side forks to swing inward toward each other into the pallet. A lifting mechanism is used to drive the side fork mechanism to rise and fall.
[0007] Furthermore, the number of the side fork mechanisms is set to two and they are symmetrically arranged on the left and right sides of the feeding area, and the pallet is provided with through holes at the front and back.
[0008] Furthermore, the linkage rod, linkage component, and side fork component are coaxially arranged front and rear. The linkage rod extends front and rear and slides back and forth. The linkage component is a linkage cam. The near ends of the two linkage components are rotatably connected to the linkage rod, and the far ends are linked to the two side fork components through a linkage shaft that passes through the side fork frame. The near ends of the two side fork components are laterally rotatably connected to the side fork frame through the two linkage shafts, and the far ends extend toward the feeding area to form a hook portion.
[0009] Furthermore, the side fork drive device includes a drive seat that is slidably mounted on the side fork frame and located on the side of the linkage rod away from the feeding area, and a drive motor mounted on the side fork frame and extending vertically. The lower end of the drive motor is provided with a drive cam that is laterally offset towards the side away from the feeding area. The drive seat is provided with a sliding groove hole extending forward and backward through it and is rotatably connected to the near ends of the two linkage rods by two drive rods respectively. The drive cam is rotatably mounted in the sliding groove hole. The drive motor drives the drive cam to swing inward towards the feeding area and pushes the drive seat to slide inward through the sliding groove hole, so as to push the near ends of the two linkage rods to swing inward through the two drive rods.
[0010] Furthermore, the two drive rods are arranged at an angle and the distance between them gradually increases towards the feeding area. The side fork is provided with two transverse slide rails extending forward and backward and two sliding seats that are slidably disposed on the two transverse slide rails respectively. The middle parts of the two linkage rods are rotatably connected to the sliding seats respectively.
[0011] Furthermore, guide grooves are recessed on the left and right sides of the frame, and a sliding part extends upward from the side of the side fork away from the feeding area. Several guide wheels that are rotatably limited in the guide grooves are provided on the front and rear sides of the sliding part. The side fork slides up and down with the frame through a longitudinal slider and a longitudinal slide rail, and is limited and guided by the several guide wheels and guide grooves. The lifting mechanism is located in the frame and drives the side fork to lift and lower through a chain and sprocket.
[0012] Furthermore, the frame is U-shaped with the opening facing upwards, and vertically extending limiting frames are symmetrically arranged on both sides of the frame, forming a limiting area between the two limiting frames for guiding the feeding and lifting of the pallet.
[0013] Therefore, the beneficial effects of this utility model are: 1. By configuring the linkage rods and linkage components, the side fork mechanism, driven by the side fork drive device, causes the near ends of the two linkage rods to swing inward toward the feeding area, while the far ends swing outward, pushing the two linkage components outward. This causes the two side forks to swing inward toward each other and into the pallet. This achieves lateral pallet retrieval, enabling the pallet unpacking machine to unpack not only pallets with holes on all four sides but also pallets with holes on only two sides, improving its adaptability. Furthermore, by shortening the linkage components, a small lateral swing of the linkage rods can drive a large inward swing of the side forks, completing an inward swing of at least 90°. This not only reduces the space occupied by the side fork mechanism but also ensures the inward swing angle of the side forks, guaranteeing the stability of the side fork movement.
[0014] 2. By setting the linkage rod, linkage component, and side fork component coaxially, and setting the linkage rod to extend forward and backward and slide forward and backward, the horizontal space occupied by the three components is minimized to the maximum extent while ensuring the linkage between the linkage rod, linkage component, and side fork component, thereby improving the structural compactness of the side fork mechanism. Furthermore, by setting the hook portion, the contact area between the side fork component and the pallet after the side fork component swings into the pallet through hole is increased, making the side fork component lift the pallet more stably.
[0015] 3. By configuring the drive cam and the sliding groove hole, the drive motor drives the drive cam to swing inward into the feeding area and pushes the drive seat inward through the sliding groove hole, thereby pushing the near ends of the two linkage rods inward through the two drive rods. This converts the rotational swing of the drive cam into the swing of the linkage rods. Furthermore, through the aforementioned linkage rod and linkage components, the drive stroke of the side fork drive device is shorter, completely avoiding the use of telescopic cylinders that directly push the linkage rods to swing. This reduces the lateral space occupied by the side fork drive device, allowing it to extend into a longitudinal space that can fully accommodate it, further improving the structural compactness of the side fork mechanism. Simultaneously, by using the drive seat and two drive rods to drive the near ends of the two linkage rods to swing, the synchronous inward swing of both side forks can be achieved with a single drive motor. This not only saves costs but also improves the structural compactness of the side fork mechanism and the synchronicity of the inward swing of the side forks.
[0016] 4. By using a drive rod set at an angle, the lateral space occupied by the drive rod is shortened while still allowing the drive rod to swing near the linkage rod, thereby further improving the structural compactness of the side fork mechanism. Attached Figure Description

[0021] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings: refer to Figure 1-4 A side-fork type decompression disc machine, comprising: The frame 1 includes a feeding area 11 for inputting pallets; specifically, the pallets are input into the feeding area 11 from both the front and rear of the conveyor line. A side fork mechanism 2 is provided on the side of the feeding area 11. The side fork mechanism 2 includes a side fork frame 21, two side forks 22 that are laterally rotatably disposed at both ends of the side fork frame 21, two linkage rods 23 that are slidably disposed on the side fork frame 21 and laterally rotatably disposed, and two linkage members 24 that are respectively linked to the two side forks 22 and whose length is shorter than the length of the side forks 22. The near ends of the two linkage rods 23 are driven to swing by the side fork driving device 25, and the far ends are respectively rotatably connected to the two linkage members 24. A lifting mechanism is used to drive the side fork mechanism 2 to lift.
[0022] The above structure, through the arrangement of linkage rods 23 and linkage members 24, allows the side fork mechanism 2, driven by the side fork drive device 25, to swing the proximal ends of the two linkage rods 23 inward toward the feeding area 11, while the distal ends swing outward, pushing the two linkage members 24 outward, thereby driving the two side forks 22 to swing inward toward each other and into the pallet. This achieves lateral pallet retrieval, enabling the pallet unpacking machine to unpack not only pallets with holes on all four sides but also pallets with holes on only two sides, improving its adaptability. Furthermore, by shortening the linkage member 24, a small lateral swing of the linkage rods 23 can drive a large inward swing of the side forks 22, completing an inward swing side fork action with at least a 90° rotation. This not only reduces the space occupied by the side fork mechanism 2 but also ensures the inward swing angle of the side forks 22, guaranteeing the stability of the side fork action.
[0023] To improve the stability of the side forks, two side fork mechanisms 2 are provided, symmetrically arranged on the left and right sides of the feeding area 11, and the pallet has through holes running through it. This allows the four corners of the side fork pallet to be stabilized by the four side fork components 22, thus improving the stability of the side forks.
[0024] To improve the structural compactness of the side fork mechanism 2, the linkage rod 23, linkage component 24, and side fork component 22 are coaxially arranged front and rear. The linkage rod 23 extends front and rear and slides back and forth. The linkage component 24 is a linkage cam. The near ends of the two linkage components 24 are rotatably connected to the linkage rod 23, and the far ends are linked to the two side fork components 22 through the linkage shaft 26 that passes through the side fork frame 21. Specifically, the linkage shaft 26 includes structures such as bearings and bushings. The near ends of the two side fork components 22 are laterally rotatably connected to the side fork frame 21 through the two linkage shafts 26, and the far ends extend toward the feeding area 11 to form a hook portion 221. The above structure arranges the linkage rod 23, linkage component 24, and side fork component 22 coaxially, with the linkage rod 23 extending forward and backward and sliding backward. This ensures the linkage between the linkage rod 23, linkage component 24, and side fork component 22 while minimizing the lateral space occupied by the three components, thus improving the structural compactness of the side fork mechanism 2. Furthermore, the hook portion 221 increases the contact area between the side fork component 22 and the pallet after the side fork moves into the pallet through hole, making the side fork component 22 more stable in lifting the pallet.
[0025] To further improve the structural compactness of the side fork mechanism 2, the side fork drive device 25 includes a drive seat 251 that is slidably mounted on the side fork frame 21 and located on the side of the linkage rod 23 away from the feeding area 11, and a drive motor 252 that is mounted on the side fork frame 21 and extends vertically. The lower end of the drive motor 252 is provided with a drive cam 253 that is laterally offset towards the side away from the feeding area 11. The drive seat 251 is provided with a sliding groove hole 254 extending forward and backward through it vertically, and is rotatably connected to the near ends of the two linkage rods 23 by two drive rods 255 respectively. The drive cam 253 is rotatably mounted in the sliding groove hole 254. The above structure, through the setting of the drive cam 253 and the sliding groove hole 254, allows the drive motor 252 to drive the drive cam 253 to swing inward toward the feeding area 11 and push the drive seat 251 to slide inward through the sliding groove hole 254, so as to push the near ends of the two linkage rods 23 to swing inward through the two drive rods 255. This allows the rotational oscillation of the drive cam 253 to be converted into the oscillation of the linkage rod 23. Furthermore, through the aforementioned linkage rod 23 and linkage member 24, the drive stroke of the side fork drive device 25 is shorter, completely avoiding the use of a telescopic cylinder that directly pushes the linkage rod 23 to oscillate. This reduces the lateral space occupied by the side fork drive device 25, allowing it to extend towards a longitudinal space that can fully accommodate it, further improving the structural compactness of the side fork mechanism 2. At the same time, by driving the drive seat 251 and the two drive rods 255 to drive the two linkage rods 23 to oscillate at their proximal ends, the synchronous inward swing of the two side fork members 22 can be achieved by a single drive motor 252. This not only saves costs but also improves the structural compactness of the side fork mechanism 2 and the synchronicity of the inward swing of the side forks of the two side fork members 22.
[0026] To further improve the structural compactness of the side fork mechanism 2, the two drive rods 255 are arranged at an angle, with the distance between them gradually increasing towards the feed area 11. The side fork frame 21 is provided with two lateral slide rails 211 extending forward and backward, and two sliding seats 212 respectively slidably mounted on the two lateral slide rails 211. The middle parts of the two linkage rods 23 are rotatably connected to the sliding seats 212. The above structure, through the angled drive rods 255, shortens the lateral space occupied by the drive rods 255 while ensuring that the drive rods 255 can push the adjacent ends of the linkage rods 23 to swing, thereby further improving the structural compactness of the side fork mechanism 2.
[0027] To improve the lifting stability of the side fork 21, guide grooves are recessed on the left and right sides of the frame 1, and a sliding part 213 extends upward on the side of the side fork 21 away from the feeding area 11. Several guide wheels 214 are provided on the front and rear sides of the sliding part 213 and are rotatably limited in the guide grooves. The side fork 21 slides up and down with the frame 1 through a longitudinal slider and a longitudinal slide rail 215 and is limited and guided by the several guide wheels 214 and the guide grooves. The lifting mechanism is located in the frame 1 and drives the side fork 21 to lift and lower through a chain and a sprocket.
[0028] To improve the stability of pallet feeding and stacking, the frame 1 is U-shaped with the opening facing upwards. Vertically extending limiting frames 3 are symmetrically arranged on both sides of the frame 1, forming a limiting area 31 between the two limiting frames 3 to guide the pallet feeding and lifting. This structure, through the setting of the limiting frames 3, can prevent pallet tilting after feeding and after lifting, thus improving the stability of pallet feeding and stacking.
[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
