Description

Technical Field

[0001] This utility model relates to the field of pallet disassembly technology, specifically to a roller-type top material device. Background Technology

[0002] In the process of pallet recycling and environmentally friendly disposal, a large number of pallets face structural damage or insufficient size adaptability due to long-term use, and need to be dismantled to maximize resource utilization. For pallets with a high proportion of intact planks, they can be dismantled and reprocessed into new pallets, packaging crates, and other products, reducing the procurement cost of timber raw materials and reducing deforestation and resource waste.

[0003] However, pallet disassembly requires precise transport to the band saw cutting station. Traditional manual handling methods have significant limitations: manual handling is not only labor-intensive and inefficient, but the pallet is also prone to tilting during transport, leading to deviations in the subsequent band saw cutting position and even causing safety accidents such as saw blade jamming and flying wood. Therefore, it is necessary to use a robotic arm in conjunction with suction cups to achieve automated pallet gripping and transport.

[0004] Currently, in the robotic arm and suction cup gripping process, the pallet generally needs to be transported to the gripping station via a roller conveyor mechanism. If the gripper is directly gripped on the roller, or if the gripper relies on the roller's start and stop mechanism, the following new problems will arise:

[0005] First, the roller conveyor mechanism is driven by chain drive to rotate the rollers to achieve conveying. If it is frequently started and stopped to cooperate with gripping, the inertia of the motor and the impact of the chain drive will aggravate the wear of the motor bearings and the stretching and deformation of the chain, thus shortening the service life of the equipment.

[0006] Secondly, intermittent start-stop will interrupt the continuous conveying process, resulting in a decrease in batch dismantling efficiency; in addition, during the shutdown of the roller conveyor mechanism, the pallet may be displaced due to inertia as the roller rotates slightly, resulting in insufficient gripping and positioning accuracy, which will affect the subsequent band saw cutting effect.

[0007] Therefore, the inventors believe that the above-mentioned technical problems are the technical problems that those skilled in the art urgently need to solve.

[0008] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] See Figures 1-6 To address the problems mentioned in the background section, this utility model provides a roller-type top-loading device to solve the aforementioned technical problems. The technical solution is as follows:

[0029] A roller-type material-ejecting device includes: a roller conveying mechanism 400, on which a plurality of rollers 420 driven by chains are spaced apart; and a material-ejecting mechanism.

[0030] The top material mechanism includes two sets of telescopic units 510, a telescopic drive unit, and several top plates 540;

[0031] Both sets of telescopic units 510 are located below the roller 420, and the two sets of telescopic units 510 are fixed at intervals on the conveyor frame 410 along the width direction of the conveyor frame 410.

[0032] Each telescopic unit 510 includes a fixed rod 511 fixed on the conveyor frame 410, a connecting rod 512 hinged to the top of the fixed rod 511, and a support rod 513 hinged to the top of the connecting rod 512.

[0033] Several top plates 540 are respectively set between two adjacent rollers 420; the bottom sides of each top plate 540 are fixed to two support rods 513 by independent top rods 560.

[0034] The telescopic drive unit is located below the roller 420 and includes a fixed rod 521 fixed on the conveyor frame 410 and a cylinder 522 hinged to the fixed rod 521; the drive rod of the cylinder 522 is hinged to the support rod 513 of one of the telescopic units 510.

[0035] In this embodiment, a synchronization rod 530 is hinged between the connecting rods 512 of the two sets of telescopic units 510.

[0036] In this embodiment, a reinforcing rod 550 is fixedly connected between the support rods 513 of the two sets of telescopic units 510 to improve the structural strength.

[0037] In this embodiment, a crossbeam 430 is fixed on the conveyor frame 410 below the roller 420 along the width direction of the conveyor frame 410; fixing rod one 511 and fixing rod two 521 are both fixed on the crossbeam 430.

[0038] In this embodiment, each roller 420 has a gear fixed on its shaft, and several gears on the same side are connected by chain drive; the two rollers on both sides are driving rollers; the driving rollers are driven by a motor.

[0039] The detailed working method of the drum-type top material device provided in this embodiment of the utility model is as follows:

[0040] (1) Before starting the device, confirm that the two sets of telescopic units 510 of the top material mechanism are in the retracted state and the top plate 540 is located below the roller. After the device is started, place the pallet to be disassembled at the input end of the roller conveyor mechanism. Under the friction of the roller rotation, the pallet moves along the length of the conveyor frame 410 to the gripping station. The roller conveyor mechanism keeps running continuously throughout the process without stopping the machine.

[0041] (2) When the pallet moves with the roller to the preset gripping position, the cylinder 522 drive rod extends. Since the cylinder body is hinged to the fixed rod 521, and the fixed rod 521 is fixed to the crossbeam 430 of the conveyor frame 410, the cylinder 522 drive rod pushes the support rod 513 of one of the telescopic units 510 that is hinged to it to rotate upward. At this time, the connecting rods 512 of the two telescopic units are hinged to each other through the synchronous rod 530. Under the linkage of the synchronous rod, the support rod 513 of the other telescopic unit rotates upward synchronously.

[0042] (3) When the support rod 513 rotates upward, it drives the connecting rod 512, which is hinged to it, to rotate around the hinge point at the top of the fixed rod 511. The rotation trajectory of the connecting rod is converted into the upward displacement of the support rod. Since the two sides of each top plate 540 are fixed to the two sets of support rods 513 by independent top rods 560, the upward movement of the support rod drives the top rod and the top plate to move upward.

[0043] (4) The top plate 540 extends upward from the gap between the adjacent rollers 420, gradually contacts the bottom surface of the pallet and continues to lift until the pallet is lifted from the surface of the rollers to a certain height; at this time the pallet is completely separated from the surface of the rollers, and the pallet ejection and positioning operation is completed.

[0044] (5) After the pallet is completely detached from the roller surface, the robotic arm 200 moves the suction cup 300 to directly above the pallet, and the suction cup starts to adsorb negative pressure. Then the robotic arm drives the adsorbed pallet to the cutting workpiece of the band saw 100 for pallet disassembly operation.

[0045] (6) When the robotic arm grabs the pallet and leaves the gripping station, the control system controls the cylinder 522 to drive the rod to retract, pulls the support rod 513 to rotate downward, and the synchronous rod is linked to the two sets of telescopic units to move again. The connecting rod 512 rotates in the opposite direction around the fixed rod, and the support rod drives the top rod and the top plate to reset downward until the top plate retracts back to below the roller gap and returns to the initial state.

[0046] The roller-type material lifting device provided in this embodiment of the utility model has the following beneficial effects: During the operation of this utility model, the pallet can be lifted without stopping the machine, avoiding equipment damage caused by frequent start and stop and improving batch disassembly efficiency; at the same time, it can prevent pallet displacement and improve positioning accuracy to ensure accurate cutting.
