Description

Technical Field

[0001] This utility model belongs to the field of pallet flipping and conveying, specifically relating to a pallet conveying mechanism that combines repositioning and flipping functions. Background Technology

[0002] In modern automated logistics warehousing, intelligent manufacturing production lines, and packaging and palletizing systems, pallets serve as the core carrier of material flow, and their efficient and stable flow control is a key link in ensuring the efficiency of the entire line.

[0003] With the increasing demand for flexible production, pallet conveying and flipping have become essential processes in many workflows. Typically, a robotic arm or manual operation is required to adjust the pallet to the desired position before flipping it. However, traditional flipping mechanisms are usually designed based on a fixed flipping trajectory, which requires a large physical space to accommodate the pallet's envelope during a 180-degree rotation. This design philosophy of trading space for function results in a large overall size of the equipment, which seriously occupies the space of the production line and also prolongs the overall pallet flipping time, ultimately affecting the production cycle and efficiency of the production line. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a pallet conveying mechanism that combines repositioning and flipping functions, which is simple in structure, has good stability, occupies little space when flipping, and improves production cycle time and efficiency.

[0005] The purpose of this utility model can be achieved by addressing the following technical problem: proposing a pallet conveying mechanism that combines repositioning and flipping functions, comprising: a base frame on which a repositioning mechanism is configured, wherein the repositioning mechanism can drive the pallet to rotate horizontally during the movement of the conveying pallet, so as to adjust the relative position of the pallet and the base frame;

[0006] A first conveying assembly and a second conveying assembly are arranged along the pallet conveying direction and are located on one side of the switching mechanism. Both the first conveying assembly and the second conveying assembly can move relative to the base frame to form a flipping cavity between them.

[0007] A flipping assembly is symmetrically arranged on both sides of the base frame. The flipping assembly includes clamping arms arranged opposite each other. The clamping arms are used to clamp the pallets carried on the first conveying assembly and the second conveying assembly, so that the flipping assembly can drive the pallets to lift and flip.

[0008] After the pallet is lifted, the first conveying component and the second conveying component move away from each other to expand the flipping cavity, so as to provide flipping space for the pallet in the flipping cavity, and to carry and convey the flipped pallet when the first conveying component and the second conveying component move closer to each other.

[0009] In the pallet conveying mechanism described above, which combines repositioning and flipping functions, both the first conveying component and the second conveying component include:

[0010] A driving component, on which a driving shaft is provided, wherein the moving direction of the driving shaft is set at an angle to the conveying direction of the pallet;

[0011] A movable frame and a conveyor belt are provided. The movable frame is connected to the end of the drive shaft, and a support frame is mounted on the movable frame. The conveyor belt is movably mounted on the support frame to realize the carrying and transfer of the pallet.

[0012] In the pallet conveying mechanism described above, which combines repositioning and flipping functions, an adjusting plate is movably connected to the movable frame, and the support frame is detachably connected to the adjusting plate to adjust the height difference between the support frame and the movable frame.

[0013] In the pallet conveying mechanism described above, which combines repositioning and flipping functions, a guide block is connected to the bottom wall of the moving frame, a guide rod is installed on the base frame, and the guide block is movably engaged with the guide rod.

[0014] In the pallet conveying mechanism described above, which combines repositioning and flipping functions, the movable frame is provided with a locking hole, and the adjusting plate is provided with an adjusting hole in the vertical direction. A fastener for connecting the locking hole is movably disposed in the adjusting hole to limit the displacement of the adjusting plate relative to the movable frame.

[0015] In the pallet conveying mechanism described above, which combines shifting and flipping functions, the shifting mechanism includes two parallel first belt conveyors and second belt conveyors, and the belts on the first belt conveyor and the second belt conveyor are in differential speed cooperation.

[0016] In the pallet conveying mechanism described above, which combines the functions of repositioning and flipping, a limit baffle is also installed on the support frame, and both ends of the limit baffle are formed with guide slopes.

[0017] In the pallet conveying mechanism described above, which combines repositioning and flipping functions, the flipping component includes:

[0018] Support frame;

[0019] A lifting cylinder and a telescopic cylinder; the lifting cylinder is mounted on the support frame, the output end of the lifting cylinder is connected to a lifting platform, and the telescopic cylinder is mounted on the lifting platform;

[0020] A tilting cylinder is installed at the output end of the telescopic cylinder. The output end of the tilting cylinder is connected to a mounting plate, and the clamping arm is detachably connected to both ends of the mounting plate.

[0021] In the pallet conveying mechanism described above, which combines repositioning and flipping functions, a fixing block is also provided on the support frame, a guide hole is provided in the fixing block, and a guide rod is connected to the bottom wall of the lifting platform, the guide rod being movably inserted into the guide hole.

[0022] In the pallet conveying mechanism described above, which combines repositioning and flipping functions, the clamping arm and the mounting plate together form a clamping cavity, and a protrusion is provided at the symmetrical axis of the pallet, the protrusion being movably abutted against the clamping cavity.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) The pallet conveying mechanism of this utility model with both repositioning and flipping functions automatically realizes the pallet adjustment function through two belt conveyors with differential speed cooperation. In addition, the dynamic opening and closing of two conveying components creates flipping space, so that the pallet can be flipped in the flipping cavity after being lifted a short distance, which greatly saves production line space. With the stable clamping of the pallet by the clamping arm, the smoothness of the flipping action is ensured. Finally, the pallet is carried and conveyed by the close proximity of the two conveying components. No additional transfer structure is required, which significantly improves the operating rhythm and working efficiency of the production line.

[0025] (2) By changing the installation position of the adjustment plate or replacing it with an adjustment plate of different specifications, the pallet conveying requirements of different heights can be adapted, which greatly enhances the versatility and adaptability of the equipment and improves the flexibility of the production line.

[0026] (3) The guide ramp can smoothly guide the edge of the pallet. Even if there is a slight deviation when the pallet enters, it can automatically return to the blocking position of the limit baffle under the action of the ramp, avoiding the pallet from getting stuck during the transport process and ensuring the smoothness and stability of the pallet transport connection of the production line.

[0039] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0040] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0041] like Figures 1 to 6 As shown, the present invention provides a pallet conveying mechanism with both transposition and flipping functions, including a base frame 2 and a transposition mechanism 21, a first conveying component 3, a second conveying component 4, and a flipping component 6.

[0042] The shifting mechanism 21 can drive the pallet 1 to rotate horizontally during the movement of the pallet 1 to adjust the relative position of the pallet 1 and the base frame 2. The first conveying component 3 and the second conveying component 4 are arranged along the conveying direction of the pallet 1. Both the first conveying component 3 and the second conveying component 4 can move relative to the base frame 2 to form a flipping cavity 50 between them. The flipping component 6 is symmetrically arranged on both sides of the base frame 2. The flipping component 6 includes clamping arms 60 arranged opposite each other. The clamping arms 60 are used to clamp the pallet 1 carried on the first conveying component 3 and the second conveying component 4 so that the flipping component 6 can drive the pallet 1 to be lifted and flipped. After the pallet 1 is lifted, the first conveying component 3 and the second conveying component 4 move away from each other to expand the flipping cavity 50, so as to provide flipping space for the pallet 1 in the flipping cavity 50, and to carry and convey the flipped pallet 1 when the first conveying component 3 and the second conveying component 4 move closer to each other.

[0043] This solution primarily aims to enable continuous conveying of pallet 1 after it has been flipped (180 degrees) during the conveying process. Specifically, as follows: Figures 1 to 5 As shown, before the pallet 1 is flipped, it is smoothly transported to the switching mechanism 21 by an upstream belt (or an external robotic arm). During the movement of the pallet 1 towards the first conveying component 3 and the second conveying component 4, the horizontal position of the pallet 1 is adjusted. This entire process requires no manual intervention, significantly saving cycle time. As the adjusted pallet 1 is smoothly transported to the first conveying component 3 and the second conveying component 4 via the switching mechanism 21, the relative positions of the first and second conveying components 3 and 4 on the base frame 2 (either in a closed position or precisely at the two ends supporting the bottom wall of the pallet 1) support the pallet 1 in a horizontal position. As the clamping arm 60 moves inward towards the pallet 1 and completes a precise clamping action, the flipping component 6 drives the clamping arm 60 along... Figure 4Moving vertically upwards, after the pallet 1 has been lifted a short distance (i.e., the pallet 1 has disengaged from the first / second conveying assembly 4), the first conveying assembly 3 and the second conveying assembly 4 begin to move away from each other until the resulting flipping cavity 50 is large enough to accommodate the flipped pallet 1 (i.e., the side walls of the flipping cavity 50 are larger than the width of the pallet 1). This operation completely eliminates the mechanical interference problem caused by the flipping of the pallet 1, and also greatly shortens the lifting height of the pallet 1, improving the production cycle and efficiency of the production line. After the flipping assembly 6 drives the pallet 1 to flip 180 degrees, the first conveying assembly 3 and the second conveying assembly 4 move closer together and reset to their initial positions (i.e., the positions that originally supported the pallet 1 in a horizontal posture). This ensures that after the pallet 1 held by the gripping arm 60 is lowered by the flipping assembly 6, it can be accurately placed back onto the first conveying assembly 3 and the second conveying assembly 4. Then, the flipped pallet 1 can be pushed to the next process using the first conveying assembly 3 and the second conveying assembly 4. As can be seen, this solution forms a flipping cavity 50 by setting a relatively movable first conveying component 3 and a second conveying component 4 on the base frame 2. Combined with the symmetrically arranged flipping components 6, it realizes the automation and high stability of the pallet 1 flipping process. This design enables the equipment to meet functional requirements while greatly reducing the space occupied on the logistics line, significantly improving space utilization, and ensuring the smooth operation of the production line.

[0044] The shifting mechanism 21 includes two parallel first belt conveyors 210 and second belt conveyors 211, with the belts on the first belt conveyor 210 and the second belt conveyor 211 forming a differential speed engagement.

[0045] like Figure 1 As shown, with the activation of the switching mechanism 21, the first belt conveyor 210 and the second belt conveyor 211 use the speed difference (i.e., the belts on the two conveyors move at different speeds) to drive the pallet 1 to rotate 90 degrees in the horizontal plane, adjusting the pallet 1 to a suitable position to ensure subsequent assembly operations. After rotation, the first belt conveyor 210 and the second belt conveyor 211 adjust their corresponding belts back to the same moving speed, thereby pushing the pallet 1 onto the first conveying assembly 3 and the second conveying assembly 4. This structure eliminates the need for two independent devices connected in series on the production line, significantly saving valuable factory space, reducing equipment procurement costs and maintenance complexity, and minimizing the time and potential risks associated with material transfer between different devices. It should be noted that the structure and working principle of the first belt conveyor 210 and the second belt conveyor 211 in this solution are the same as described in detail, and the implementation and working principle of the differential speed coordination structure can be referenced from the existing rotary positioner technology, which will not be elaborated here.

[0046] Both the first conveying assembly 3 and the second conveying assembly 4 include: a driving member 51 on which a driving shaft 510 is disposed, the moving direction of the driving shaft 510 being set at an angle to the conveying direction of the pallet 1; a movable frame 52 and a conveyor belt 54, the movable frame 52 being connected to the end of the driving shaft 510, a support frame 53 being mounted on the movable frame 52, and the conveyor belt 54 being movably disposed on the support frame 53 to realize the carrying and transfer of the pallet 1.

[0047] For example Figure 2 and Figure 4 As shown, when the drive component 51 (such as a hydraulic cylinder or pneumatic cylinder) is activated, the power is transmitted to the drive shaft 510 to extend or retract. It is worth noting that the axis of the drive shaft 510 is angled to the conveying direction of the pallet 1 (90° in this embodiment). This allows the moving frame 52 to shift the support frame 53 and its conveyor belt 54, thus completing the carrying and conveying of the pallet 1 and facilitating spatial clearance. This greatly optimizes the spatial layout of the equipment, making the conveying assembly more compact, especially suitable for use in confined spaces. The coordinated operation of the support frame 53 and the conveyor belt 54 forms a stable carrying and conveying structure. This design ensures the smooth operation of the pallet 1 during normal conveying, and during tipping and clearance, the entire conveying assembly moves synchronously, ensuring consistent action and reducing the control complexity and manufacturing cost of the equipment.

[0048] The bottom wall of the movable frame 52 is connected to a guide block 520, and a guide rod 20 is installed on the base frame 2. The guide block 520 is movably engaged with the guide rod 20.

[0049] Furthermore, such as Figure 2 and Figure 3 As shown, this solution forms a precise guiding and limiting mechanism through the movable engagement between the guide block 520 and the guide rod 20. During the process of the first conveying component 3 and the second conveying component 4 moving towards each other (closer or farther away) to adjust the size of the flipping cavity 50, the guide rod 20 plays a limiting and guiding role on the guide block 520, ensuring that the moving frame 52 moves linearly along the predetermined trajectory, preventing the moving frame 52 from deflecting, shaking or jamming during the movement. This not only improves the accuracy and stability of the movement of the conveying components, but also effectively reduces the wear of moving parts, extends the service life of the equipment, and ensures the accurate reset of the flipping action.

[0050] An adjusting plate 55 is movably connected to the movable frame 52, and the support frame 53 is detachably connected to the adjusting plate 55 to adjust the height difference between the support frame 53 and the movable frame 52. Figure 3 and Figure 4As shown, this solution can adapt to the conveying requirements of pallets 1 with different height requirements by changing the installation position of the adjustment plate 55. This modular and adjustable design greatly enhances the versatility and adaptability of the equipment, enabling the same set of flipping conveyor mechanism to be compatible with the conveying of pallets 1 of various specifications, reducing the cost of replacing the entire machine due to product changes, and improving the flexibility of the production line.

[0051] The movable frame 52 has a locking hole 521, and the adjusting plate 55 has an adjusting hole 550 along the vertical direction. A fastener for connecting the locking hole 521 is movably installed in the adjusting hole 550 to limit the displacement of the adjusting plate 55 relative to the movable frame 52.

[0052] Furthermore, such as Figure 4 As shown, when the height of the support frame 53 needs to be adjusted, the operator can pre-release the fastener (which can be a screw, bolt, or other structure not shown in the figure) from the locking hole 521 (preferably a threaded hole). As the height difference between the support frame 53 and the moving frame 52 changes (i.e., the adjusting plate 55 can slide up and down along the adjusting hole 550 to adjust the height), the relative position between the adjusting hole 550 and the locking hole 521 also changes. At this time, by aligning the fastener with the locking hole 521 and connecting its interior, the support frame 53 can be restricted to the required height position, so as to adapt to the receiving and conveying operation of the pallet 1 at different height positions, thus improving the flexibility of the mechanism. The overall structure is simple and easy to operate. The precise setting of the bearing height can be completed without additional complex tooling, ensuring the stability of the support frame 53 after height adjustment, avoiding accidental displacement of the adjusting plate 55 during equipment operation, and ensuring the safety of the conveying process.

[0053] A limiting baffle 56 is also installed on the support frame 53. The limiting baffle 56 is used to limit the relative position of the pallet 1 and the support frame 53. Figure 2 and Figure 3 As shown, it is worth noting that the limiting baffle 56 is located on one side of the conveyor belt 54. This limiting baffle 56 provides a certain lateral constraint on the pallet 1, effectively preventing the pallet 1 from shifting or running off course due to inertia or vibration during transport, thus ensuring the stability of the pallet 1 during transport. Furthermore, during the process of placing the flipped pallet 1 vertically onto the conveyor belt 54, the limiting baffles 56 on both sides provide guidance and positioning for the pallet 1, effectively preventing tilting when the flipped pallet 1 is placed back on the conveyor belt 54, which would affect the smoothness of subsequent process connections.

[0054] Preferably, in this design, both ends of the limiting baffle 56 are formed with guide slopes 560. When the pallet 1 is conveyed to the carrier frame 53, the guide slopes 560 can smoothly guide the edge of the pallet 1. Even if there is a slight deviation when the pallet 1 enters, it can automatically return to the position between the two limiting baffles 56 under the action of the guide slopes 560 (while ensuring that the pallet 1 falls accurately onto the conveyor belt 54 for stable conveying). This avoids the severe vibration or damage caused by the pallet 1 directly hitting the baffle, protects the overall quality of the pallet 1 from being affected, and also makes the loading and positioning process of the pallet 1 smoother and gentler.

[0055] The flipping assembly 6 includes: a support frame 61; a lifting cylinder 62 and a telescopic cylinder 63, wherein the lifting cylinder 62 is mounted on the support frame 61, the output end of the lifting cylinder 62 is connected to a lifting platform 620, and the telescopic cylinder 63 is mounted on the lifting platform 620; a flipping cylinder 64 is mounted on the output end of the telescopic cylinder 63, the output end of the flipping cylinder 64 is connected to a mounting plate 640, and the clamping arm 60 is detachably connected to both ends of the mounting plate 640.

[0056] As the conveyor belt 54 on the support frame 53 transfers the pallet 1 to... Figure 2 When the position shown is reached, the clamping arm 60 is aligned with the position of the pallet 1 to be clamped. The telescopic cylinder 63 drives the tilting cylinder 64 to move towards the pallet 1 until the clamping arm 60 extends into the pallet 1. It is worth noting that during the clamping process, two symmetrically arranged mounting plates 640 abut against the side walls of the pallet 1, working in conjunction with the clamping arm 60 to abut and limit the movement of the inner wall of the pallet 1, effectively ensuring the smoothness and stability of the pallet 1 during tilting. After the pallet 1 is stably clamped, the lifting cylinder 62 drives the lifting platform 620 along... Figure 6 The vertical lifting mechanism disengages the bottom of pallet 1 from the conveyor belt 54 (at which point pallet 1 is positioned above the conveyor belt 54), ensuring that the position of pallet 1 does not interfere with the movement of the moving frame 52, which drives the support frame 53 and the conveyor belt 54 away from each other. As the output of the flipping cylinder 64 drives the mounting plate 640 and clamping arm 60 to rotate, pallet 1 can complete a 180° flipping operation. At this point, the moving frame 52 drives the support frame 53 and conveyor belt 54 to reset. The lifting cylinder 62 drives the lifting platform 620 to descend, placing the flipped pallet 1 back onto the conveyor belt 54. Combined with the guiding and positioning functions of the limit baffle 56, the stability of the conveyor belt 54 in transporting the flipped pallet 1 to the next process is ensured. This multi-degree-of-freedom pneumatic control structure features fast response, high control precision, and the detachable clamping arm 60 (accessible via screws or bolts) connected to the mounting plate 640 facilitates maintenance and replacement. This makes the entire flipping process smooth and controllable, suitable for high-speed automated production lines.

[0057] The support frame 61 is also provided with a fixing block 65, and a guide hole 650 is provided in the fixing block 65. The bottom wall of the lifting platform 620 is connected to a guide rod 621, which is movably inserted into the guide hole 650.

[0058] Furthermore, such as Figure 5 As shown, when the lifting cylinder 62 drives the lifting platform 620 to move up and down, the guide rod 621 slides in the guide hole 650, which strictly limits the movement trajectory of the lifting platform 620 and prevents the lifting platform 620 from shaking, tilting or rotating during the lifting process. This ensures the verticality and stability of the clamping arm 60 when clamping the pallet 1, and ensures that the pallet 1 is lifted smoothly. It avoids the pallet 1 falling off or uneven force on the flipping mechanism caused by the shaking of the lifting platform 620, which greatly improves the safety and reliability of the equipment operation.

[0059] Furthermore, the clamping arm 60 and the mounting plate 640 together form a clamping cavity 600. A protrusion 10 is provided at the symmetrical axis of the pallet 1, and the protrusion 10 moves and abuts against the inside of the clamping cavity 600. As shown in 4, this design utilizes the structural features of the pallet 1 itself (protrusion 10) for clamping. That is, the clamping cavity 600 provides clearance space for the protrusion 10. At the same time, the clamping arm 60 extends into the bottom of the pallet 1 and abuts against both sides of the protrusion 10. Combined with the synergistic clamping force of the two mounting plates 640 on the outer walls of the two ends of the protrusion 10, this clamping method results in more concentrated and reasonable force distribution, preventing the pallet 1 from tipping over or rotating during the flipping process, and ensuring the absolute safety of the material during the flipping process.
