DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] The embodiment of the present application provides a pallet conveying device, which can solve the problem that traditional pallet processing and conveying devices in the related art often rely on manual operation when positioning the pallet, which is not only cumbersome to operate but also easy to introduce errors, thereby affecting processing efficiency and product quality.

[0028] See also Figure 1-Figure 3 A pallet conveying device includes: a bracket 1, an isolation mechanism 3 and an auxiliary processing mechanism 4, wherein a conveyor 2 for conveying pallets is arranged on the bracket 1, and a preset station 21 for temporarily storing pallets and a pre-processing station 22 for processing pallets are arranged in sequence on the conveyor 2; the isolation mechanism 3 is arranged on the conveyor 2, and is used for positioning and isolating the preset station 21 and the pre-processing station 22; the isolation mechanism 3 includes two groups of driving members 31, two isolation plates 32 and a sensor 33, the two groups of driving members 31 are respectively arranged on the preset station 21 and the pre-processing station 22, the driving members 31 are connected to the isolation plates 32, and are used to control the lifting and lowering of the isolation plates 32, the sensor 33 is arranged on the preset station 21, and is used to locate the position of the pallet; the auxiliary processing mechanism 4 includes a mounting frame 41, a lifting assembly 42 and a flipping assembly 43 which are arranged in sequence on the pre-processing station 22, the lifting assembly 42 is connected to the flipping assembly 43 and is used to drive the flipping assembly 43 to lift and lower, and the flipping assembly 43 is used to control the flipping of the pallet.

[0029] In actual operation, the pallet is placed at the starting end of the conveyor 2. As the conveyor 2 runs, the pallet moves along the conveying direction. During the movement, it first reaches the preset station 21. The function of the preset station 21 is to temporarily store the pallet to be processed to ensure that the pallet is in the correct position and state before entering the pre-processing station 22.

[0030] At the preset station 21, the sensor 33 will monitor the position of the pallet in real time. Once the sensor 33 detects that the pallet has arrived at the preset station 21, it will immediately send a signal to start the isolation mechanism 3. After receiving the command, the drive member 31 will start working to control the isolation plate 32 to rise. The function of the isolation plate 32 is to ensure that when the pre-processing station 22 processes the pallet, it avoids interference when the pallet moves from the preset station 21 to the pre-processing station 22, and prevents the position of the placed pallets from being offset or colliding with each other.

[0031] At this time, the auxiliary processing mechanism 4 on the pre-processing station 22 starts to work. The auxiliary processing mechanism 4 includes a mounting frame 41, a lifting component 42 and a turning component 43.

[0032] The mounting frame 41 provides a stable support platform for the entire auxiliary processing mechanism 4, maintaining stability throughout the entire processing process. The lifting component 42 is responsible for driving the lifting and lowering action of the flipping component 43. According to the processing requirements, the lifting component 42 can lift the flipping component 43 to an appropriate height to facilitate processing of the pallet thereon. After the processing is completed, the flipping component 43 controls the flipping of the pallet. When the pallet needs to be flipped, the flipping component 43 will act according to the instructions to flip the pallet to a specified angle, and the pallet leaves the conveyor 2 to complete the unloading operation.

[0033] After the unloading step is completed, the auxiliary processing mechanism 4 returns to its original position. During the entire process described above, the isolation mechanism 3 and the conveyor 2 always remain in working condition to ensure that the pallets between the preset station 21 and the pre-processing station 22 do not interfere with each other.

[0034] After the processing of the above-mentioned pallets is completed, the driving member 31 is started again to control the descent of the isolation plates 32 on the preset station 21 and the pre-processing station 22 to restore to their original positions. The conveyor 2 drives the pallet on the preset station 21 to continue moving. When the pallet enters the pre-processing station 22, the next pallet moves to the preset station 21. When the sensor 33 detects that the pallet has reached the preset station 21, the sensor 33 sends a command to control the isolation plate 32 to rise. In this way, a cyclic processing workflow can be formed for the pallets.

[0035] The pallet conveying equipment realizes the automated conveying, positioning and auxiliary processing of pallets, so that pallets can be conveyed and processed according to predetermined paths and methods, improving production efficiency and reducing labor costs. It also facilitates the unloading of processed pallets, reduces the difficulty of manual operations and improves overall work efficiency.

[0036] It is understandable that when the equipment starts to operate initially, the operator loads the pallet. After being transported by the conveyor 2, the pallet first enters the preset station 21. At this time, the pallet does not enter the pre-processing station 22. During this process, the auxiliary processing mechanism 4 will start without load.

[0037] Specifically, when the equipment is started, the conveyor 2 starts working, driving the pallet to move from the starting end to the preset station 21. At this time, since the pallet has not yet reached the pre-processing station 22, the auxiliary processing mechanism 4 is in standby status and has no actual processing tasks. In order to ensure the normal operation and preparation status of the auxiliary processing mechanism 4, the auxiliary processing mechanism 4 will start with no load and complete a self-inspection operation.

[0038] Specifically, Figure 1 and Figure 4As shown, the driving member 31 in this embodiment includes a support frame 311 and a cylinder 312 connected to each other, one side of the support frame 311 is connected to the conveyor 2, and the piston rod of the cylinder 312 is connected to the isolation plate 32.

[0039] One side of the support frame 311 is connected to the conveyor 2, and the driving member 31 can be firmly fixed on the conveyor to ensure its stability during operation. The piston rod of the cylinder 312 is connected to the isolation plate 32 and the sensor 33. When the sensor 33 detects that the pallet has reached the preset station 21, the sensor 33 will send an instruction, and the cylinder 312 will perform a telescopic action according to the instruction, thereby driving the isolation plate 32 to rise and fall.

[0040] Furthermore, in this embodiment, the sensor 33 is a photoelectric sensor or a pressure sensor, and the sensor 33 is electrically connected to the two cylinders 312 respectively.

[0041] In this embodiment, according to actual application requirements, the sensor 33 may be a photoelectric sensor or a pressure sensor. Both sensors have high sensitivity and accuracy and can reliably detect the position and state of the tray.

[0042] The photoelectric sensor detects the existence and position of an object by emitting and receiving light. When the pallet enters the preset station 21, the photoelectric sensor senses the existence of the pallet and sends a signal to control the action of cylinder 1 312 and drive the isolation plate 32 to rise, thereby achieving the positioning and isolation of the pallet; the pressure sensor determines the position and state of the object by detecting the pressure exerted by the object on it. When the pallet is placed on the preset station 21, the pressure sensor will be affected by the pressure of the pallet, thereby triggering a signal output, and according to the received pressure signal, it will also control cylinder 1 312 to perform corresponding actions.

[0043] Regardless of which sensor is used, they are all electrically connected to the two cylinders 312 to ensure timely transmission and accurate execution of control signals. This electrical connection method enables the sensor to monitor the position of the pallet in real time and control the action of the cylinder 312 as needed, thereby achieving precise control of the pallet conveying process.

[0044] Specifically, the lifting assembly 42 in this embodiment includes a cylinder 421 and a connecting plate 422 connected to each other. The cylinder 421 is disposed on the mounting frame 41. The piston rod of the cylinder 421 is connected to the connecting plate 422.

[0045] Cylinder 2 421 serves as the power source of the lifting component 42 and is firmly set on the mounting frame 41, which ensures the stability of cylinder 2 421 and is also beneficial to its connection and coordinated work with other components. The piston rod of cylinder 2 421 is connected to the connecting plate 422, and the connecting plate 422 can be driven to perform lifting and lowering actions through the telescopic movement of the piston rod.

[0046] The connecting plate 422 is also connected to the flip assembly 43, so that the power of the cylinder 2 421 can be directly transmitted to the flip assembly 43, thereby realizing the lifting control thereof. The structure and size of the connecting plate 422 are reasonably designed, can bear a large load, and ensure the stability and accuracy of the lifting movement.

[0047] It can be understood that in this embodiment, a telescopic rod is arranged at the bottom of the connecting plate 422, and the bottom end of the telescopic rod is in contact with the ground, so that the stability of the lifting and lowering of the flip assembly is improved by the telescopic rod.

[0048] Specifically, the flip assembly 43 in this embodiment includes a frame 431, a flap 432, two rotating shafts 433, and a cylinder three 434. The frame 431 is set on the connecting plate 422, and the two rotating shafts 433 are relatively set at one end of the frame 431. The flap 432 is embedded in the frame 431, and one side of the flap 432 is rotatably connected to the two rotating shafts 433. The cylinder three 434 is hinged on the mounting frame 41, and the piston rod of the cylinder three 434 is hinged to the bottom of the other side of the flap 432. The frame 431 is U-shaped, the frame 431 is adapted to the flap 432, and the flap 432 is abutted against the connecting plate 422.

[0049] The frame 431 serves as the basis of the entire flip assembly, and its structure is stable and strong. The frame 431 is set on the connecting plate 422 and is connected to the lifting assembly 42 through the connecting plate 422, thereby ensuring that the flip assembly 43 can rise and fall with the lifting assembly 42.

[0050] Two rotating shafts 433 are relatively arranged at one end of the frame 431 to provide support for the rotation of the flap 432. The flap 432 is embedded in the frame 431, and one side of the flap 432 is rotatably connected to the two rotating shafts 433, so that the flap 432 can flip around the rotating shaft 433.

[0051] The cylinder 3 434 is hingedly mounted on the mounting frame 41 as the power source of the flip assembly 43. The piston rod of the cylinder 3 434 is hingedly connected to the bottom of the other side of the flap 432. The flap 432 can be driven to flip through the telescopic movement of the piston rod. This design makes the flipping action faster and more accurate, and is convenient for the staff to unload materials.

[0052] The frame 431 is designed to be U-shaped, which is compatible with the shape of the flap 432, which not only improves the stability of the structure but also enables the flap 432 to remain stable during the flipping process.

[0053] In this embodiment, the flap 432 is provided with positioning pins adapted to the bottom of the tray.

[0054] Specifically, the setting of the locating pins takes into account key factors such as the size, shape and weight of the pallet, ensuring that they can accurately and firmly fit with the bottom of the pallet to avoid deviation during the pallet processing.

[0055] It can be understood that the present embodiment also includes a control module, which is electrically connected to the sensor 33, the cylinder 1 312, the cylinder 2 421 and the cylinder 3 434 respectively.

[0056] The control module is closely connected with the sensor 33, cylinder one 312, cylinder two 421 and cylinder three 434 by electrical connection, so as to realize precise control of each key component of the equipment.

[0057] As a sensing device, the sensor 33 can monitor the position and status of the pallet in real time and transmit the relevant information to the control module. The control module determines whether the pallet has reached the preset station 21 based on the received sensor signal, and controls the extension and retraction action of the cylinder 312 accordingly, thereby driving the isolation plate 32 to rise or fall, thereby realizing the positioning and isolation of the pallet.

[0058] Secondly, when the pallet is accurately positioned, the control module will control the telescopic movement of cylinder 2 421 according to processing requirements. Cylinder 2 421 serves as the power source of the lifting assembly 42, and drives the connecting plate 422 and the flip assembly 43 to rise and fall to the appropriate position through the telescopic movement of its piston rod.

[0059] During the flipping action phase, the control module controls the telescopic movement of the cylinder three 434 according to the preset program and processing requirements. The cylinder three 434 drives the flap 432 to flip through the extension and contraction of its piston rod, thereby realizing the flipping of the pallet.

[0060] This embodiment further includes a plurality of gaskets 5 , which are disposed on the isolation plate 32 and are located on a side of the isolation plate 32 close to the sensor 33 .

[0061] By adding the gasket 5 as an auxiliary element, the provision of the gasket 5 helps to adjust the relative position between the isolation plate 32 and the sensor 33, ensuring that the sensor 33 can accurately and timely detect the lifting and lowering action of the isolation plate 32.

[0062] The gasket 5 can also play a role in buffering and shock absorption. When the isolation plate 32 is raised or lowered, the gasket 5 can absorb part of the impact force and vibration.

[0063] In addition, the material and thickness of the gasket 5 can also be selected according to specific needs to meet different working environments and processing requirements.

[0064] Specifically, the conveyor 2 in this embodiment includes two support plates 201, and the two support plates 201 are relatively arranged on the bracket 1. Transmission wheels 202 are rotatably arranged at both ends of the support plates 201. The transmission wheel 202 is located between the two support plates 201. Conveyor belts 203 are arranged for transmission on the outer sides of the two transmission wheels 202 on the same side. A transmission rod 204 is arranged between the two relatively transmission wheels 202. A driving member 205 is arranged on one side of the support plates 201. The driving member 205 is connected to the transmission wheel 202 on one side and is used to drive the transmission wheel 202 to rotate.

[0065] Among them, the driving component 205 includes a shell, a driving motor, a reducer, two pulleys and a belt. The shell is arranged on a side support plate 201, the reducer is arranged on the shell, the driving motor is arranged on the reducer, the driving motor output shaft is connected to the reducer input shaft, the two pulleys are both rotatably arranged inside the shell, and the belt transmission is arranged between the outer sides of the two pulleys; the reducer output shaft passes through the shell and is connected to one side of the pulley, and one end of the other side pulley passes through the shell and the support plate 201 in sequence and is connected to the transmission wheel 202.

[0066] In addition, the conveyor belt 203 may be a belt or chain conveyor belt.

[0067] The two support plates 201 are relatively arranged on the bracket 1, providing a solid foundation for the stable operation of the equipment. At both ends of the support plates 201, there are rotatable transmission wheels 202, which are located between the two support plates 201. They work together to drive the operation of the conveyor belt 203. The conveyor belt 203 is the core component of the conveyor 2. It is in the form of a belt or chain conveyor belt, which can carry pallets and realize continuous and smooth transportation. The conveyor belt 203 is driven by the transmission action of the transmission wheel 202 and circulates along the trajectory of the support plate 201, thereby driving the pallet to move between the preset station 21 and the pre-processing station 22.

[0068] In order to drive the transmission wheel 202 to rotate, a driving member 205 is specially provided in the present embodiment. The driving member 205 is installed on a side support plate 201. The driving motor is the power source of the driving member 205. It reduces the rotation speed to a suitable range through a reducer, and then transmits the power to the transmission wheel 202 through a pulley and a belt. This design is not only compact in structure, but also has high transmission efficiency, which can ensure the stable operation of the conveyor.

[0069] In addition, in order to further improve the stability and reliability of the conveyor, a transmission rod 204 is also set between the two relative transmission wheels 202 in this embodiment. The function of the transmission rod 204 is to ensure that the two transmission wheels 202 always rotate synchronously, thereby preventing the conveyor belt 203 from running off track or slipping.
