Description

Technical Field

[0001] This application relates to the field of production and packaging technology, and in particular to a pallet transfer device. Background Technology

[0002] In related technologies, operators collect and stack empty pallets from the end of the production line. Once a certain number of empty pallets have accumulated, they are transported to the feeding station using a turnover logistics vehicle. This solution requires manual labor, and the pallets are relatively large, requiring material carts for return transport, which is time-consuming and labor-intensive. In addition, material carts need to be placed at both the beginning and end of the production line for connection, occupying a large area and making pallet loading and unloading inconvenient. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a pallet transfer device that can realize automatic pallet return and improve return efficiency.

[0005] A conveying assembly includes a first conveying mechanism for laterally conveying pallets;

[0006] A lifting mechanism is provided at one end of the first conveying mechanism, and the lifting mechanism is used to lift the pallet to a position flush with the conveying surface of the first conveying mechanism;

[0007] A pushing mechanism is used to push the pallet lifted by the lifting mechanism toward the first conveying mechanism;

[0008] A material drop guide mechanism is located at the other end of the first conveying mechanism, and the material drop guide mechanism is used to guide the pallet conveyed by the first conveying mechanism downward.

[0009] Furthermore, the material dropping guide mechanism includes a guide structure and a transmission structure. The guide structure is inclined, and the higher side of the guide structure is flush with the conveying surface of the first conveying mechanism. The transmission structure defines a conveying channel, and the guide structure is used to guide the pallet to the conveying channel.

[0010] Furthermore, the material dropping guide mechanism includes a guide roller, which is disposed within the conveying channel and is used to abut against the pallet.

[0011] Furthermore, the material dropping guide mechanism includes a movable rod, which is rotatably disposed at the end of the conductive structure away from the guide structure.

[0012] Furthermore, the lifting mechanism includes a bracket, a lateral movement assembly, and a lifting assembly. The lateral movement assembly is mounted on the bracket, and the lifting assembly is used to drive the bracket to rise and fall.

[0013] Furthermore, the lifting mechanism includes a position sensor mounted on the bracket, the position sensor being used to detect the position of the tray.

[0014] Furthermore, the pushing mechanism includes a pushing block and a driving mechanism. The pushing block is located on the reverse extension side of the conveying direction of the first conveying mechanism, and the driving mechanism is used to drive the pushing block to move toward the side closer to the first conveying mechanism.

[0015] Furthermore, the first conveying mechanism includes a conveying structure and a limiting structure. The limiting structure protrudes from the conveying surface of the conveying structure, and the limiting structure and the conveying structure define a guide groove for at least partially accommodating the pallet.

[0016] Furthermore, the conveying assembly includes a second conveying mechanism, which is located on one side of the lifting mechanism and is used to convey the pallet to the lifting mechanism.

[0017] Furthermore, the conveying assembly also includes a third conveying mechanism, which is located on one side of the second conveying mechanism and is offset from the second conveying mechanism.

[0018] As can be seen from the above technical solutions, the embodiments of this application have at least the following beneficial effects:

[0019] In the pallet transfer device provided in this application embodiment, the lifting mechanism can lift the pallet located in the lifting mechanism to one side of the conveying surface of the first conveying mechanism. Then, the pushing mechanism can push the pallet towards the first conveying mechanism, so that the pallet is transferred from the lifting mechanism to the conveying surface of the first conveying mechanism. Subsequently, the first conveying mechanism can transport the pallet to the dropping guide mechanism, and the dropping guide mechanism will guide the pallet downward. In this way, automatic pallet return can be realized. Compared with the method of manually collecting and stacking pallets and then transferring them using a turnover logistics vehicle, this application embodiment can effectively improve the pallet return efficiency and reduce the workload.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] See Figure 1 As shown, embodiments of this application disclose a pallet transfer device that can effectively improve the return efficiency of pallet 1 and reduce workload.

[0036] The following will combine Figures 1 to 7 The pallet return device disclosed in the embodiments of this application will be explained and described in detail.

[0037] like Figure 1 As shown, an embodiment of this application discloses a pallet transfer device, including a conveying component, a lifting mechanism 200, a pushing mechanism 300, and a dropping guide mechanism 400.

[0038] Specifically, the conveying assembly includes a first conveying mechanism 110 for laterally conveying the pallet 1; a lifting mechanism 200 disposed at one end of the first conveying mechanism 110 for lifting the pallet 1 to a position flush with the conveying surface of the first conveying mechanism 110; a pushing mechanism 300 for pushing the pallet 1 lifted by the lifting mechanism 200 toward the first conveying mechanism 110; and a dropping guide mechanism 400 disposed at the other end of the first conveying mechanism 110 for downward guiding the pallet 1 conveyed by the first conveying mechanism 110.

[0039] In the pallet transfer device provided in this application embodiment, the lifting mechanism 200 can lift the pallet 1 located in the lifting mechanism 200 to one side of the conveying surface of the first conveying mechanism 110, and the pushing mechanism 300 can push the pallet 1 towards the first conveying mechanism 110, so that the pallet 1 is transferred from the lifting mechanism 200 to the conveying surface of the first conveying mechanism 110. Then the first conveying mechanism 110 can transport the pallet 1 to the dropping guide mechanism 400, and the dropping guide mechanism 400 can conduct the pallet 1 downward to facilitate the picking up of the pallet 1.

[0040] In this way, pallet 1 can be automatically returned. Compared with the method of manually collecting and stacking pallets 1 and then transferring them using a turnover logistics vehicle, the embodiment of this application can effectively improve the return efficiency of pallet 1 and reduce the workload.

[0041] In some embodiments of this application, see Figure 1 and Figure 6The material feeding guide mechanism 400 includes a guide structure 420 and a transmission structure 430. The guide structure 420 is inclined, and the higher side of the guide structure 420 is flush with the conveying surface of the first conveying mechanism 110. The transmission structure 430 defines a conveying channel 431. The guide structure 420 is used to guide the pallet 1 to the conveying channel 431. The conveying channel 431 can accommodate the pallet 1. After the guide structure 420 guides the pallet 1 from the first conveying mechanism 110 into the conveying channel 431, the pallet 1 can move along the conveying channel 431 toward the outlet of the conveying channel 431.

[0042] In one possible implementation, see Figure 6 The guide structure 420 includes several inclined guide rods, one end of which is flush with the conveying surface of the first conveying mechanism 110, while the other end is lower than the conveying surface of the first conveying mechanism 110. Thus, when the pallet 1 moves along the first conveying mechanism 110 to the guide structure 420, the pallet 1 will tilt due to gravity, and the tilted pallet 1 can smoothly enter the conveying channel 431 and move along the conveying channel 431.

[0043] It is worth understanding that the tilt direction of the guide structure 420 can be set as needed. For example, along the conveying direction of the first conveying mechanism 110, the left and right sides of the guide structure 420 have different heights, and the guide structure 420 is tilted from one side to the other.

[0044] In one possible implementation, see Figure 6 The transmission structure 430 includes spaced-apart transmission rods, and a transmission channel 431 is defined between the spaced-apart transmission rods.

[0045] It should be noted that the conveying channel 431 should cooperate with the guide structure 420 so that the guide structure 420 can guide the tray 1 into the conveying channel 431.

[0046] In some embodiments of this application, the material dropping guide mechanism 400 includes a guide roller, which is disposed within the conveying channel 431 and is used to abut against the pallet 1. Thus, as the pallet 1 falls along the conveying channel 431, the guide roller, by contacting the pallet 1, can reduce the conveying speed of the pallet 1, thereby reducing the possibility of damage to the pallet 1 due to high-speed collisions with external objects.

[0047] In some embodiments of this application, please refer to... Figure 6The material dropping guide mechanism 400 includes a movable rod 440, which is rotatably disposed at the end of the transmission structure 430 away from the guide structure 420. Specifically, the material dropping guide mechanism 400 includes a mounting frame 410, on which the guide structure 420 and the transmission structure 430 are mounted, and the movable rod 440 is rotatably connected to the mounting frame 410. When the pallet 1 is conveyed downward along the conveyor channel 431, the pallet 1 slides out of the conveyor channel 431. At this time, the pallet 1 can be blocked at least partially by the movable rod 440, preventing the pallet 1 from being bounced away after leaving the conveyor channel 431. The movable rod 440 is rotatably connected to the mounting frame 410. When the pallet 1 is removed, the pallet 1 gradually flips over, and the movable rod 440 rotates due to the force exerted by the pallet 1, thus facilitating the removal of the pallet 1.

[0048] In some embodiments of this application, see Figures 2 to 4 The lifting mechanism 200 includes a bracket 210, a lateral movement assembly 220, and a lifting assembly 230. The lateral movement assembly 220 is mounted on the bracket 210, and the lifting assembly 230 is used to drive the bracket 210 to rise and fall. The lifting mechanism 200 has a pallet 1 placement position, and the lateral movement assembly 220 is used to drive the pallet 1 to move laterally, so that the pallet 1 moves from the outside to the pallet 1 placement position.

[0049] It is worth understanding that the tray 1 placement position can be formed on the transverse component 220 or on the bracket 210, and is not limited here.

[0050] In one possible implementation, the lateral movement assembly 220 includes two rotating belts spaced apart and arranged laterally. When the two rotating belts come into contact with the tray 1, they are driven to rotate, thereby causing the tray 1 to move laterally.

[0051] Furthermore, the interval between the two rotating belts is set to be adjustable, so that the lifting mechanism 200 can be adapted to pallets 1 of different sizes.

[0052] In one possible implementation, the lifting assembly 230 includes pulleys, a lifting belt, and a lifting drive. The lifting mechanism 200 includes a support frame 240 with two pulleys spaced apart. The lifting belt is fitted onto the two pulleys, and the lifting drive drives the pulleys to rotate, thereby moving the lifting belt. The bracket 210 is fixedly connected to one position of the lifting belt. By driving the lifting belt to reciprocate, the pallet 1 can be lifted from a low position to a position flush with the conveying surface of the first conveying mechanism 110. Using the lifting belt to drive the bracket 210 to lift and lower increases the lifting speed, thereby improving efficiency.

[0053] It should be noted that in some other embodiments, the lifting mechanism 200 includes a lifting belt, pulleys, a lifting drive component, and pallets. Two pulleys are spaced apart and mounted on the support frame 240. The lifting belt is fitted onto the two pulleys. The lifting drive component drives the pulleys to rotate, thereby moving the lifting belt. There are two lifting belts, spaced apart, each equipped with a pulley and a lifting drive component. Multiple pallets are circumferentially spaced on the outer surfaces of the two lifting belts. The pallets at the same height on the two lifting belts together lift the pallet 1. The movement of the lifting belts can drive the pallets to move, thereby lifting the pallet 1.

[0054] In some embodiments of this application, see Figure 3 and Figure 4 The lifting mechanism 200 includes a position sensor 250, which is mounted on the bracket 210. The position sensor 250 is used to detect the position of the pallet 1. Specifically, by setting the position sensor 250, the pallet 1 can be detected to be in position, ensuring that the pallet 1 is lifted only after it has moved to the preset position, which helps to improve the safety of the operation.

[0055] In this embodiment, the lifting mechanism 200 includes a baffle 260, which is mounted on the bracket 210. The baffle 260 is used to abut against the top of the support frame 240 to achieve a limiting effect.

[0056] In some embodiments of this application, see Figure 1 , Figure 2 and Figure 5 The pushing mechanism 300 includes a pusher block 310 and a drive mechanism 320. The pusher block 310 is located on the extended side of the conveying surface of the first conveying mechanism 110, and the drive mechanism 320 is used to drive the pusher block 310 to move toward the side closer to the first conveying mechanism 110. When the lifting mechanism 200 lifts the pallet 1 to the same height as the conveying surface of the first conveying mechanism 110, the pusher block 310 is located on the side of the pallet 1 away from the first conveying mechanism 110. Then, the drive mechanism 320 drives the pusher block 310 to move toward the first conveying mechanism 110 to push the pallet 1 onto the first conveying mechanism 110.

[0057] In one possible implementation, the drive mechanism 320 includes a rotary drive member, rotating wheels, and a pushing power belt. There are two rotating wheels spaced apart. The pushing power belt is fitted onto the rotating wheels. The rotary drive member drives the rotating wheels to rotate, thereby driving the pushing power belt. The push block 310 is fixedly connected to one position of the pushing power belt. By driving the pushing power belt to reciprocate, the push block 310 can be driven to reciprocate.

[0058] It is worth understanding that in some other embodiments, the drive mechanism 320 may also be a lead screw and slider mechanism or other structures that can drive the push block 310 to reciprocate linearly.

[0059] In this embodiment, the pushing mechanism 300 includes a guide rail 330, and the pushing block 310 is slidably connected to the guide rail 330.

[0060] In some embodiments of this application, see Figure 1 The first conveying mechanism 110 includes a conveying structure and a limiting structure 111. The limiting structure 111 protrudes from the conveying surface of the conveying structure, and the limiting structure 111 and the conveying structure define a guide groove for at least partially accommodating the pallet 1. In this way, the guide groove can effectively prevent the pallet 1 from detaching from the conveying structure.

[0061] In one possible implementation, the conveying structure includes a plurality of rolling wheels spaced apart along the conveying direction. When the pushing mechanism 300 pushes the pallet 1 lifted by the lifting mechanism 200 toward the first conveying mechanism 110, the pallet 1 can abut against the tail of the pallet 1 already on the first conveying mechanism 110. As the pushing mechanism 300 pushes the pallet 1 lifted by the lifting mechanism 200 toward the first conveying mechanism 110, the pusher can also synchronously push the pallet 1 already on the first conveying mechanism 110 forward, thereby realizing the sequential forward pushing of the pallets 1. Thus, while realizing the movement of the pallet 1 on the first conveying mechanism 110, the power requirement can be reduced, and the equipment cost can be lowered.

[0062] In some embodiments of this application, see Figure 1 The pallet transfer device includes a second conveying mechanism 120, which is located on one side of the lifting mechanism 200. The second conveying mechanism 120 is used to convey the pallet 1 to the lifting mechanism 200.

[0063] In some embodiments of this application, see Figure 1 The pallet transfer device also includes a third conveying mechanism 130, which is located on one side of the second conveying mechanism 120 and is offset from the second conveying mechanism 120.

[0064] The pallet transfer device of this application embodiment is described in detail below with reference to a specific example. It should be noted that the following embodiment is merely an exemplary description and should not be construed as limiting the embodiments of this application.

[0065] See Figures 1 to 7 As shown, Figure 7 In the diagram, the arrows indicate the flow direction of tray 1. Figure 7 The pallet pick-up position 2 and the pallet feeding position 3 are also shown.

[0066] The pallet transfer device of this embodiment includes a conveying component, a lifting mechanism 200, a pushing mechanism 300, and a dropping guide mechanism 400. The conveying component includes a first conveying mechanism 110, a second conveying mechanism 120, and a third conveying mechanism 130.

[0067] Specifically, one end of the second conveying mechanism 120 is connected to the pallet feeding position 3. After the pallet 1 is placed in the second conveying mechanism 120, the second conveying mechanism 120 can transport the pallet 1 to the lifting mechanism 200. The lifting mechanism 200 lifts the pallet 1 to the same height as the conveying surface of the first conveying mechanism 110. Then the pushing mechanism 300 pushes the pallet 1 from the lifting mechanism 200 to the first conveying mechanism 110. As the pallet 1 is continuously pushed out from the lifting mechanism 200, each pallet 1 on the first conveying mechanism 110 gradually moves forward. When pallet 1 moves along the first conveying mechanism 110 to the material drop guide mechanism 400, pallet 1 falls under the action of gravity. After pallet 1 falls and moves to the pallet picking position 2, the operator can take out pallet 1 and place it on the third conveying mechanism 130. After pallet 1 is conveyed along the third conveying mechanism 130 to the vicinity of the second conveying mechanism 120, another operator transfers pallet 1 to the second conveying mechanism 120. Then, pallet 1 is conveyed to the designated position of the lifting mechanism 200 under the action of the second conveying mechanism 120, and this cycle continues.

[0068] The pallet transfer device of this application embodiment is applicable to scenarios including but not limited to those requiring pallet 1 production processes.

[0069] For example, the pallet transfer device of this application embodiment can be applied to the process of assisting in the application of screen cover plate workpieces. The pallet transfer device can enable the pallet 1 to be automatically returned, which helps to improve work efficiency.
