Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a pallet changing device. Background Technology

[0002] Paper shakers are key pieces of equipment in modern printing and packaging production lines. Their main function is to straighten, loosen, and push stacks of paper to ensure that each sheet is accurately positioned before entering subsequent processing equipment (such as printing presses and die-cutting machines), avoiding quality problems such as double sheets, blank sheets, or inaccurate positioning. After being processed by the paper shaker, the stacks are usually placed on pallets for easy transfer and temporary storage within the workshop.

[0003] In the existing production process, there are many types of pallets used to carry paper stacks. Some pallets can only be used in special scenarios and cannot be used for the entire conveying system, requiring pallet replacement operations midway through the process. Currently, the pallet replacement operation for paper stacks is basically done manually. Operators need to first remove the original pallet carrying the paper stack, and then use manpower or auxiliary equipment to move, align and place the heavy paper stack onto the new pallet. This process has a low degree of automation and low work efficiency. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figure 1This utility model provides a pallet changing device, including a pallet flipping mechanism 1 and a pallet changing mechanism 2. The pallet flipping mechanism 1 is used to flip a first pallet stack 710 to obtain a second pallet stack 720, and the pallet changing mechanism 2 is used to replace the second pallet 750 at the bottom of the replacement part 730 with a first pallet 740. The pallet flipping mechanism 1 includes a first flipping machine 10, a first roller conveyor 20 located at the input end of the first flipping machine 10, and a second roller conveyor 30 located at the output end of the first flipping machine 10. The first roller conveyor 20 is used to transport the first pallet stack 710 into the first flipping machine 10, and the first flipping machine 10 is used to flip the first pallet stack 710 180° in a first direction to obtain the second pallet stack 720. The second roller conveyor 30 is used to transport the second pallet stack 720. Both the first pallet stack 710 and the second pallet stack 720 include multiple first pallets 740. The pallet changing mechanism 2 includes a second tilting machine 40, a loading / unloading roller conveyor 50, and an operating component 60. The loading / unloading roller conveyor 50 is connected to the second tilting machine 40, and the operating component 60 is located above the loading / unloading roller conveyor 50. The loading / unloading roller conveyor 50 is used to transport the part to be replaced 730, and a second pallet 750 is provided at the bottom of the part to be replaced 730. The operating component 60 is used to clamp the first pallet 740 on the top of the second pallet stack 720 and place it on the part to be replaced 730. The second tilting machine 40 is used to rotate the part to be replaced 730 180° in a first direction. The operating component 60 is also used to clamp the second pallet 750 out after the second tilting machine 40 rotates the part to be replaced 730. The pallet tilting mechanism 1 and the pallet changing mechanism 2 improve the automation level of pallet changing, reduce the cost of traditional manual handling and changing, and improve the changing efficiency.

[0023] Specifically, both the first pallet 740 and the second pallet 750 include a placement plate for placing paper stacks and a support leg located on one side of the placement plate. The replacement part 730 may be, for example, a paper stack with a pallet. The first pallet stack 710 may be, for example, a collection of multiple first pallets 740 stacked together, with the support legs of the first pallets 740 in the first pallet stack 710 facing downwards; the second pallet stack 720 may be, for example, a collection of multiple first pallets 740 stacked together, with the support legs of the first pallets 740 in the second pallet stack 720 facing upwards.

[0024] Specifically, the specific working process of the pallet changing device of this utility model is as follows: First, flip the tray: The first pallet stack 710 is placed on the first roller conveyor 20, which transports it to the first tilting machine 10. The tilting machine 10 tilts the first pallet stack 710 180° to obtain the second pallet stack 720, with the legs of the first pallet 740 in the second pallet stack 720 facing upwards. The tilted second pallet stack 720 is then transported to the second roller conveyor 30 and then to the pallet changing mechanism 2. The pallet changing mechanism 2 replaces the second pallet 750 at the bottom of the replacement part 730 with the first pallet 740. The pallets are tilted by the pallet tilting mechanism 1. Secondly, tray replacement: The replacement part 730, with a second pallet 750, is transported from the paper stack storage area (not shown) to the loading / unloading roller conveyor 50. The replacement part 730 includes the second pallet 750 and a paper stack placed on the second pallet 750. When the loading / unloading roller conveyor 50 moves the replacement part 730 to the corresponding position of the operating component 60, the operating component 60 picks up the first pallet 740 from the second pallet stack 720 and places it on the replacement part 730, that is, the first pallet 740 of the second pallet stack 720 is placed above the paper stack, so that the first pallet 740 and the second pallet 750 are located at the top and bottom of the replacement part 730, respectively. Then, it is transported to the second tilting machine 40 by the loading / unloading roller conveyor 50 and tilted 180 degrees, so that the first pallet 740 and the second pallet 750 are located at the bottom and top of the replacement part 730, respectively. The replacement part 730, which has been flipped and has the first tray 740 and the second tray 750, is conveyed out of the second flipping machine 40 and then conveyed to the area of ​​the corresponding operating component 60 by the loading and unloading roller conveyor 50. After the operating component 60 removes the second tray 750 located above the replacement part 730, the tray replacement of the replacement part 730 is completed.

[0025] Among them, the first direction mentioned above (such as Figure 1 As shown, the first pallet stack 710 and the replacement part 730 can be flipped, for example, vertically, and the flipping can be, for example, up and down.

[0026] Furthermore, if the paper stack in the replacement part 730 is a single paper stack, the operating component 60 can clamp a pallet of the corresponding size and place it on the replacement part 730. If the paper stack in the replacement part 730 is a combined paper stack composed of multiple small-sized paper stacks, and is uniformly placed on a second pallet 750, if it is necessary to split the combined paper stack for separate conveying, the operating component 60 can place the first pallet 740 corresponding to the multiple small-sized paper stacks on the small-sized paper stacks, and then through the flipping of the second flipping machine 40 and the clamping of the second pallet 750 by the operating component 60, the combined small-sized paper stacks can be split and replaced separately, realizing the replacement of the combined small-sized paper stacks in one go, thus improving work efficiency.

[0027] The beneficial effects of this utility model are: The pallet is flipped by setting up a first flipping machine 10, a first roller conveyor 20 and a second roller conveyor 30, and the pallet is replaced by setting up a second flipping machine 40, a loading and unloading roller conveyor 50 and an operating component 60. This achieves full automation and intelligence of the process, improves pallet replacement efficiency, and enables the paper stacks to flow smoothly throughout the production and logistics system, thereby improving the overall coordination efficiency of the process.

[0028] See Figure 2In some embodiments, the first flipping machine 10 includes a first base 110, a rotating member 120, two first clamping members 130, two first roller conveyors 140, a first drive mechanism, a second drive mechanism, and a third drive mechanism. The rotating member 120 is rotatably disposed on the first base 110, and a conveying space 121 for conveying a first pallet stack is formed within the rotating member 120. The two first clamping members 130 are symmetrically disposed within the conveying space 121. The two first roller conveyors 140 are respectively disposed on the two first clamping members 130, and the first roller conveyors 140 are used to convey the first pallet stack 710 and the second pallet stack 720. The first drive mechanism is driven to rotate the rotating member 120; the second drive mechanism is driven to move the two first clamping members 130 towards or away from each other; the third drive mechanism is driven to convey the first roller conveyor 140, enabling it to transport the first pallet stack 710 and the second pallet stack 720. The first roller conveyor 140 is, for example, a conveyor belt fitted onto the first clamping members 130. The surface of the conveyor belt is provided with a silicone anti-slip layer to increase the friction between the first roller conveyor 140 and the first and second pallet stacks 710 and 720, ensuring stable transport of the first pallet stacks 710 and 720. In some embodiments, the rotating member 120 is a cylinder, and the first drive mechanism can be used to drive the cylinder to rotate. The first, second, and third drive mechanisms can be, for example, drive motors. The two first clamping members 130 can be, for example, clamping plates.

[0029] Specifically, when the first flipping machine 10 is not working, the two first clamping members 130 are in the open state, located at both ends of the conveying space 121, ensuring that the first pallet stack 710 can smoothly enter the conveying space 121 within the rotating member 120. When the third drive mechanism drives the first roller conveyor 140 to rotate so that the first pallet stack 710 is fully inside the conveying space 121 and located between the two first clamping members 130, the second drive mechanism drives the two first clamping members 130 to move towards each other to clamp the first pallet stack 710. When the two first clamping members 130 are in the clamped state, the first roller conveyor 140 does not rotate, preventing the first pallet stack 710 from being transported out of the rotating member 120 before flipping. Then, the first drive mechanism drives the rotating component 120 to rotate, causing the rotating component 120 to rotate the first pallet stack 710 by 180 degrees to form the second pallet stack 720. The second drive mechanism drives the two first clamping components 130 to move in a direction away from each other, so that the two first clamping components 130 are in the open state. The third drive mechanism then drives the first roller conveyor 140 to rotate, causing the second pallet stack 720 to be output from the first flipping machine 10. By setting the two first clamping components 130 to lock the first pallet stack 710, it is prevented that the first pallet stack 710 will fall out of the rotating component 120 during the flipping process and be damaged.

[0030] When the first tilting machine 10 is in the open state, the first roller conveyor 140 located at the bottom of the two first roller conveyors 140 is flush with the first roller conveyor 20 and the second roller conveyor 30, which facilitates the smooth transport of the first pallet stack 710 through the first roller conveyor 20 into the first tilting machine 10, and facilitates the output of the second pallet stack 720 from the first tilting machine 10 to the second roller conveyor 30.

[0031] See Figure 3 and Figure 4In some embodiments, the second flipping machine 40 includes a second mounting base 410, a mounting plate 420, two second clamping members 430, two second roller conveyors 440, a fourth drive mechanism, a fifth drive mechanism, and a sixth drive mechanism. The mounting plate 420 is rotatably mounted on the second mounting base 410. The two second clamping members 430 are located on the side of the mounting plate 420 opposite to the second mounting base 410 and are slidably connected to both ends of the mounting plate 420. The two second roller conveyors 440 are respectively mounted on the two second clamping members 430 for conveying the replacement part 730. The fourth drive mechanism is drivenly connected to the mounting plate 420 for driving the mounting plate 420 to rotate. The fifth drive mechanism is drivenly connected to the second clamping members 430 for driving the two second clamping members 430 to move in a direction that approaches or moves away from each other. The sixth drive mechanism is drivenly connected to the second roller conveyors 440 for driving the second roller conveyors 440 to rotate to transport the replacement part 730. The second roller conveyor 440 is, for example, a conveyor belt sleeved on the second clamping member 430, with a silicone anti-slip layer on its surface to increase the friction between the second roller conveyor 440 and the replacement part 730, ensuring that the second roller conveyor 440 stably conveys the replacement part 730; the fourth drive mechanism, the fifth drive mechanism and the sixth drive mechanism may be, for example, drive motors.

[0032] Specifically, when the second flipping machine 40 is not working, the two second clamping members 430 are in the open state and are located at both ends of the mounting plate 420, ensuring that the replacement part 730 can smoothly enter the second flipping machine 40. When the sixth drive mechanism drives the second roller conveyor 440 to rotate so that the replacement part 730 is fully entered and located between the two second clamping members 430, the fifth drive mechanism drives the two second clamping members 430 to move towards each other to clamp the replacement part 730. When the two second clamping members 430 are in the clamped state, the second roller conveyor 440 does not rotate to prevent the replacement part 730 from being transported out of the second flipping machine 40 before flipping. Then, the fourth drive mechanism drives the mounting plate 420 to rotate, causing the mounting plate 420 to rotate the second clamping member 430 and the replacement part 730 together by 180°. The fifth drive mechanism drives the two second clamping members 430 to move away from each other, so that the two second clamping members 430 are in the open state. The sixth drive mechanism then drives the second roller conveyor 440 to rotate, driving the flipped replacement part 730 out of the second flipping machine 40. By setting the two second clamping members 430 to lock the replacement part 730, it is prevented from falling out of the second flipping machine 40 during the flipping process, which would cause damage to the equipment and products and affect the work process.

[0033] When the second tilting machine 40 is in the open state, the second roller conveyor 440 at the bottom of the two second roller conveyors 440 is flush with the loading and unloading roller conveyor 50, so that the replacement part 730 can be smoothly conveyed into the second tilting machine 40 through the loading and unloading roller conveyor 50, and the replacement part 730 can be output from the second tilting machine 40 to the loading and unloading roller conveyor 50.

[0034] See Figure 5 In some embodiments, the operating component 60 includes a support 610, an operating component 620, a seventh drive mechanism, and an eighth drive mechanism. The support 610 is disposed corresponding to the loading / unloading roller conveyor 50, and the operating component 620 is slidably connected to the support 610. The seventh drive mechanism is drivenly connected to the operating component 620 to move the operating component 620 along the support 610. The eighth drive mechanism is drivenly connected to the operating component 620 to grip the second pallet 750 on the replacement part 730 and the first pallet 740 of the second pallet stack 720. The seventh and eighth drive mechanisms may be, for example, drive motors.

[0035] When the replacement part 730 is placed on the loading / unloading roller conveyor 50 and initially conveyed towards the second flipper 40, when the replacement part 730 is transported to the corresponding area of ​​the operating component 620, the eighth drive mechanism drives the operating component 620 to clamp the first pallet 740 on the second pallet stack 720. Then, the seventh drive mechanism drives the operating component 620 to move the first pallet 740 to the position corresponding to the replacement part 730, and then drives the operating component 620 to release and place the first pallet 740 above the replacement part 730, so that the paper stack is located between the first pallet 740 and the second pallet 750. After being flipped by the second flipper 40, the first pallet 740 is located at the bottom of the paper stack, and the second pallet 750 is located at the top of the paper stack. After the eighth drive mechanism drives the operating component 620 to clamp the second pallet 750 located at the top of the paper stack, the seventh drive mechanism drives the operating component 620 to move the second pallet 750 until it is completely separated from the replacement part 730, thereby realizing the replacement of the paper stack pallet. The above operations improve the overall efficiency of pallet replacement and further enhance the automation level of the device.

[0036] Furthermore, a first pallet placement area and a second pallet placement area are respectively provided on both sides of the loading and unloading roller conveyor 50. Both the first pallet placement area and the second pallet placement area are provided corresponding to the support member 610, and the operating member 620 can move between the first pallet placement area and the second pallet placement area. After the first pallet stack 710 is flipped to form the second pallet stack 720, it can be placed in the first pallet placement area. After the operating member 620 picks up the second pallet 750, it can place the second pallet 750 in the second pallet placement area, thus completing the collection of the second pallet 750.

[0037] See Figure 5 In some embodiments, the support member 610 includes two symmetrically arranged first mounting rods 611 and a second mounting rod 612 connected between the two first mounting rods 611. The two first mounting rods 611 are located on both sides of the loading / unloading roller conveyor 50, and the second mounting rod 612 is correspondingly arranged above the loading / unloading roller conveyor 50. The operating member 620 is slidably connected to the second mounting rod 612. The second mounting rod 612 provides motion guidance for the movement of the operating member 620. An operating space is formed between the two first mounting rods 611 and the second mounting rod 612, allowing the operating member 620 to move smoothly and ensuring that the operating member 620 can smoothly complete the clamping and placement work. The first pallet placement area and the second pallet placement area are located between the two first mounting rods 611 and are both corresponding to the second mounting rod 612.

[0038] See Figure 5 In some embodiments, the operating element 620 includes a movable block 621, a connecting rod 622, and an operating hand 623. The movable block 621 is movably mounted on the second mounting rod 612 and connected to the seventh drive mechanism. The connecting rod 622 is connected to the movable block 621. The operating hand 623 is located at the end of the connecting rod 622 near the loading / unloading roller conveyor 50. The eighth drive mechanism is driven by the connecting rod 622, causing the connecting rod 622 to move towards or away from the loading / unloading roller conveyor 50 and causing the operating hand 623 to move. Automated pallet gripping and transportation are achieved by configuring the movable block 621, the connecting rod 622, the operating hand 623, and the drive mechanism. Specifically, the movable block 621 can drive the connecting rod 622 and the operating hand 623 to move along the second mounting rod 612. The eighth drive mechanism drives the connecting rod 622 to move towards or away from the loading / unloading roller conveyor 50, that is, to move along a first direction. When a pallet needs to be grasped, the eighth drive mechanism drives the operator 623 to move towards the loading / unloading roller conveyor 50 to contact and grip the first pallet 740 or the second pallet 750. Then, the operator 623 moves away from the loading / unloading roller conveyor 50, providing space for the connecting rod 622 to move the operator 623. By driving the connecting rod 622 up and down via the eighth drive mechanism, sufficient safety clearance is ensured between the operator 623 and the pallet and other equipment or materials below during horizontal movement, improving the safety and reliability of the device operation and preventing interference or collisions. The operator can be, for example, a robotic arm, gripper, or suction cup.

[0039] See Figure 1In some embodiments, the pallet changing device further includes a conveying mechanism 3, disposed between the pallet flipping mechanism 1 and the pallet changing mechanism 2, for conveying the second pallet stack 720 or the replacement part 730. The conveying mechanism 3, for example, is an intelligent transport vehicle or a conveyor belt, etc., which can transport the flipped second pallet stack 720 to the pallet changing mechanism 2, facilitating subsequent handling by the operating component 60 to grasp and replace it. The intelligent transport vehicle can automatically transport items up and down, and can employ existing intelligent transport vehicles. Furthermore, an automated trolley can also be used to transport the first pallet stack 710 from the preceding process to the first roller conveyor 20, or to transport the replacement part 730 (without pallet replacement) to the loading / unloading roller conveyor 50, or to transport the pallet stacks and pallets that have been palletized out of the subsequent process.
