Description

Technical Field

[0001] This invention relates to a centering mechanism, specifically a centering and correction mechanism and method for a loading pallet. Background Technology

[0002] When loading pallets, the pallets are often misaligned or tilted during transport from the conveyor to the warehouse. Therefore, it's necessary to straighten and center the pallets before placing them in the warehouse. Currently, the centering method involves installing two side panels on both sides of the pallet. These two side panels push against the pallet simultaneously, and their orientation is fixed, thus guiding the pallet to the correct direction. However, this method requires clearing the sides of the pallet to accommodate the side panels and their drive mechanisms, taking up considerable space and making it impractical in small-scale applications. Summary of the Invention

[0003] To address the shortcomings of the prior art, this invention provides a pallet centering and correction mechanism and method. The invention features a trolley in the form of a walking machine at the bottom, which carries the centering mechanism and allows it to move left and right. When receiving a pallet, it can freely connect to the pallet without any power source. Once the pallet is in place, the drive unit starts to move the pallet to the centering position, achieving correct placement in the warehouse. It occupies little space, is easy to use, and requires no interference for centering.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: a feeding pallet centering and correction mechanism, including a base frame;

[0005] The walking assembly moves on the base frame;

[0006] The centering mechanism includes a drive end and a motion end, wherein the drive end is disposed on the base frame and the motion end is connected to the limiting member;

[0007] The limiting component is fixed at both ends to the walking component and moves synchronously with the walking component. A limiting groove is provided in the middle to limit the movement stroke of the moving end.

[0008] Support beams, fixed to the walking assembly, are used to support the pallet;

[0009] During the process of the pallet contacting and being transported to the support beam, the drive end is not powered, and the traveling assembly moves with the pallet; after the pallet has fully reached the support beam, the drive end provides power to drive the traveling end to move along the base frame so that the pallet is centered.

[0010] Furthermore, the base frame includes two parallel rails, each with a stop block at its end to limit the travel of the walking component; the rails are fixed with crossbeams for fixedly mounting the drive end.

[0011] Furthermore, the walking assembly includes a support frame and walking wheels, the walking wheels traveling along the track; the two ends of the limiting member are fixed to the support frame.

[0012] Furthermore, the limiting member includes two parallel limiting main beams, both ends of which are fixed to the support beams of the support frame; two limiting grooves are formed between the two limiting main beams, both ends of which are closed; the moving end is located in the two limiting grooves.

[0013] Furthermore, a limiting rod is fixed to the inner side of each end of the two limiting main beams, and a limiting plate is fixed to each end of the two limiting rods at the same end. The limiting groove is formed between the two limiting rods at the same end and the two corresponding limiting plates.

[0014] Furthermore, the driving end of the centering mechanism includes a motor reducer, a reduction gearbox, and a main shaft connected to the reduction gearbox, the main shaft being connected to two moving ends.

[0015] Furthermore, the moving end includes a connecting rod and two swing rods. The center of the connecting rod is fixedly connected to the main shaft. Both ends of the connecting rod are provided with a rotating shaft, and both ends of the connecting rod are respectively connected to the two swing rods through the rotating shaft. The free end of the swing rod is hinged with a sliding wheel, and the two sliding wheels are respectively located in the two limiting grooves.

[0016] Furthermore, it also includes a guide device disposed on the walking assembly for guiding the tray.

[0017] A method for centering and correcting the deviation of a loading pallet includes the following steps:

[0018] The pallet is conveyed to the position of the walking component by the feeding mechanism. At this time, the motor reducer at the drive end is not powered. The pallet contacts the support beam. Under the guidance of the guiding device, the walking component moves left and right with the pallet, and the pallet is successfully loaded onto the support beam.

[0019] The motor reducer at the drive end provides power to drive the main shaft to rotate, and the main shaft drives the connecting rod to rotate around the main shaft as the center;

[0020] When the connecting rod rotates, it drives the position where the swing rod is connected to the connecting rod to rotate. The sliding wheel at the free end of the swing rod is limited in the limiting groove. When the position where the swing rod is connected to the connecting rod rotates, it drives the two sliding wheels to make linear motion in the two limiting grooves respectively, thereby driving the limiting component to move linearly, which in turn drives the traveling component to move linearly along the base frame, placing the traveling component in the centering position, thereby centering the pallet.

[0021] Pallets are received into the warehouse.

[0022] In summary, the present invention has achieved the following technical effects:

[0023] When the material is loaded into the warehouse, the mechanism moves to put the transfer machine in a state of no power on the left and right. When the forklift loads the material, the pallet touches the correction guide mechanism, causing the mechanism to shift left and right with the position of the pallet. When the forklift leaves, the correction motor of the mechanism is activated, and the transfer machine body is corrected to the center position, and the pallet is normally loaded into the warehouse. When the material is unloaded, the mechanism moves to put the transfer machine in the center position, and the pallet is normally unloaded.

[0024] This invention features a small trolley at the bottom, which carries the centering mechanism and moves it left and right. When receiving a pallet, it can connect to pallets at any angle and position without any power. Once the pallet is in place, the drive unit moves the pallet to the centering position, achieving correct placement in the warehouse. It occupies little space, is easy to use, and requires no interference for centering. Attached Figure Description

[0039] Example:

[0040] like Figure 1 The image shown is a three-dimensional schematic diagram of a pallet centering and correction mechanism. Figure 2 As shown Figure 1The front view includes a base frame 1; a traveling assembly 2 that travels on the base frame 1; used for left and right movement for centering and correction; a centering mechanism 7, including a drive end and a moving end, the drive end being located on the base frame 1 and the moving end being connected to a limiting member 6; the drive end is used to drive the moving end to make linear movement, and the moving end drives the limiting member 6 to move; the limiting member 6 is fixed at both ends to the traveling assembly 2 and moves synchronously with the traveling assembly 2, and a limiting groove is provided in the middle to limit the movement stroke of the moving end; the limiting member 6 drives the traveling assembly 2 to move along the base frame 1, and controls the movement stroke of the traveling assembly 2 under the limitation of the limiting groove; a support beam 4, fixed on the traveling assembly 2, is used to carry the pallet; during the process of the pallet contacting and being transported to the support beam 4, the drive end has no power, and the traveling assembly 2 moves with the pallet; after the pallet has completely reached the support beam 4, the drive end provides power to drive the moving end to move so that the traveling assembly 2 moves along the base frame 1, so that the pallet is centered.

[0041] In this invention, during the initial storage process, the drive unit is in a non-powered state, while the moving unit can move freely, allowing the traveling assembly 2 to move freely along the base frame 1 to adapt to the pallet's position before storage. At this time, the traveling assembly 2 is misaligned. Once the pallet is fully in place, the drive unit begins to provide power, controlling the moving unit to move and move the traveling assembly to the aligned position. At this point, the traveling assembly is aligned with the storage vehicle, meaning the pallet is aligned with the storage vehicle, thus achieving pallet correction and alignment.

[0042] like Figure 3 The diagram shows a frame of the base frame 1 and the traveling assembly 2. The base frame 1 includes two parallel tracks 101, each with a stop block at its end to limit the travel of the traveling assembly 2. A crossbeam 102 is fixed to the track 101 for mounting the drive end. The base frame 1 is fixed to the ground or a platform, serving as a stationary component, thus keeping the drive end of the centering mechanism 7 in a fixed state, maintaining stability, and ensuring a stable connection with the feeding mechanism (not shown).

[0043] The traveling component 2 includes a support frame 201 and traveling wheels 202, which travel along the track 101. The two ends of the limiting member 6 are fixed to the support frame 201. When the limiting member 6 is driven, the traveling component 2 moves accordingly to align with the center and achieve centering and correction functions. The traveling component 2 is a movable component that carries the pallet for centering. The travel of the traveling component 2 is limited, allowing it to travel only a short distance to the left or right to achieve centering within that distance. In actual use, the error between the centering mechanism and the feeding mechanism is small, so a short travel distance is sufficient. The traveling component has two types of power: when there is no power at the drive end, the pallet controls the movement; when there is power at the drive end, the drive end controls the movement. Both walking modes of the traveling component 2 do not require manual intervention, are automatically adapted, are easy to use, have a high degree of automation, and can achieve unattended operation.

[0044] like Figure 4 The diagram shows a schematic of the limiting component 6. The limiting component 6 includes two parallel limiting main beams 601. Both ends of the limiting main beams 601 are fixed to the support beams 4 of the support frame 201. The limiting main beams 601 are aligned with the traveling direction, facilitating control of the trolley's movement direction. Two limiting grooves 603 are formed between the two limiting main beams 601. Both ends of the limiting grooves 603 are closed, restricting the stroke of the centering mechanism and preventing the pallet from deflecting the traveling component 2 when it enters the traveling component 2. The moving end is located within the two limiting grooves 603. Furthermore, a limiting rod 602 is fixed to the inner side of each end of the two limiting main beams 601. Limiting plates 604 are fixed to both ends of the two limiting rods 602 at the same end. A limiting groove 603 is formed between the two limiting rods 602 at the same end and the corresponding two limiting plates 604. The limiting plate 604 has a U-shaped structure, with waist-shaped holes on the two side plates of the U-shape to adjust the length of the limiting groove 603 to adapt to different scenarios. The ends of the two limiting main beams 601 are fixed to the support beams of the support frame 201 through connecting plates 605. The support beams 4 are also the guide rails and load-bearing beams that support the pallet, which can both fix the limiting main beams 601 and receive the pallet as a track.

[0045] like Figure 5 The diagram shown is a schematic of the centering mechanism, as follows: Figure 6 What is shown is Figure 5 The top view shows that the driving end of the centering mechanism 7 includes a motor reducer 701, a reduction gearbox 702, and a main shaft 703 connected to the reduction gearbox 702. The main shaft 703 has two moving ends. The motor reducer 701 and the reduction gearbox 702 are fixed on the base frame 1 and remain stationary to ensure stability. When the motor reducer 701 is powered, it controls the movement of the main shaft 703 through the reduction gearbox 702. When the motor reducer 701 is not powered, the main shaft 703 can move freely, which can accommodate the situation where the pallet enters the traveling assembly 2 and also accommodate the situation where the pallet is centered.

[0046] The moving end includes a connecting rod 704 and two swing rods 706. The center of the connecting rod 704 is fixedly connected to the main shaft 703. Both ends of the connecting rod 704 are provided with a rotating shaft 705. The two ends of the connecting rod 704 are respectively connected to the two swing rods 706 through the rotating shafts 705. The free end of the swing rod 706 is hinged with a sliding wheel 707. The two sliding wheels 707 are respectively located in two limiting grooves 603.

[0047] like Figure 7 The diagram shows a top view of the centering mechanism connected to the limiting member. When the drive end is not powered, the moving end and the main shaft 703 are in a free state, that is, the traveling assembly 2 is in a free state. The pallet comes from a misaligned position and contacts the support beam 4. Under the action of the guide device 5, the pallet remains stationary in a straight position on the feeding mechanism. Therefore, the pallet touches the guide device 5, and the guide device 5 swings with the pallet and the traveling assembly 2 according to the pallet's position. The pallet enters the traveling assembly 2. At this time, the traveling assembly 2 is tilted and misaligned. After the pallet is fully in place, the drive end is powered, and the reducer controls the linkage 704 to move, causing the two sliding wheels 707 to move closer to the center, pulling the limiting member 6 from the tilted position back to the centering position, thus achieving centering.

[0048] It also includes a guide device 5, mounted on the traveling assembly 2, for guiding the pallet. For example... Figure 8 The diagram shows the guide device 5, which includes a guide base plate 501 fixed on the support frame 201. A first guide plate 502, a second guide plate 503, and a third guide plate 504 are installed on the guide base plate 501 to allow the pallet to enter smoothly.

[0049] A method for centering and correcting the deviation of a loading pallet includes the following steps:

[0050] The pallet is conveyed to the position of the walking component 2 by the feeding mechanism. At this time, the motor reducer 701 at the drive end is not powered. The pallet contacts the support beam 4. Under the guidance of the guide device 5, the walking component 2 follows the pallet to shift left and right, and the pallet is successfully loaded onto the support beam 4.

[0051] The motor reducer 701 at the drive end provides power to drive the main shaft 703 to rotate, and the main shaft 703 drives the connecting rod 704 to rotate around the main shaft 703.

[0052] When the connecting rod 704 rotates, it drives the position where the swing rod 706 is connected to the connecting rod 704 to rotate. The sliding wheel 707 at the free end of the swing rod 706 is limited in the limiting groove 603. When the position where the swing rod 706 is connected to the connecting rod 704 rotates, it drives the two sliding wheels 707 to make linear motion in the two limiting grooves 603 respectively, thereby driving the limiting member 6 to move linearly, thereby driving the walking component 2 to move linearly along the base frame 1, placing the walking component 2 in the centering position, thereby centering the pallet.

[0053] Pallets are received into the warehouse.

[0054] When the pallet is being shipped out, the walking component 2 is aligned to receive the pallet, and then the pallet is output.

[0055] The correction mechanism of this invention adopts the form of a transfer machine, using a correction motor (SEWK19DRN63M4 / BE / 0.18KW / 143rpm) and a gearbox (NRV075i=1:80) to drive the transfer machine to perform left and right offset correction actions. When loading materials into the warehouse, the mechanism operates to keep the transfer machine in a state of no power on the left and right. When the forklift loads materials, the loading pallet touches the correction guide mechanism, causing the mechanism to shift left and right following the position of the pallet. When the forklift leaves, the correction motor of the mechanism operates, and the transfer machine body is corrected to the center position, and the pallet is normally loaded into the warehouse. When unloading materials, the mechanism operates to keep the transfer machine in the center position, and the pallet is normally unloaded.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way.
