Description

Technical Field

[0001] The invention belongs to the technical field of material handling, and in particular relates to a stacker structure for intelligent material handling. Background Art

[0002] As an important transport vehicle, stacker is mainly used for loading and unloading, stacking, and short-distance transportation of palletized goods. It has the remarkable characteristics of simple structure, flexible operation, good micro-motion and high explosion-proof safety performance, especially excellent operation performance in narrow passages and limited spaces, making it an ideal equipment for loading and unloading pallets in high-bay warehouses and workshops.

[0003] At present, in the actual process of stacking trucks controlling the lifting and stacking of goods, motors are usually selected as driving devices, and the lifting mechanism is controlled to drive the lifting and lowering operations of the goods. However, there are certain shortcomings in the use of motors as driving devices in traditional stacking trucks. Specifically, the output power of the motor is generally fixed. This means that when the stacker is stacking heavier objects, the output power of the motor cannot be increased in time according to actual needs. It should be noted that heavier objects usually require greater driving force to be transported and lifted. If the output power of the motor remains unchanged in this case, it is very likely that the motor will be in an overloaded state for a long time. Long-term overload operation will greatly increase the possibility of motor damage. On the other hand, when carrying lighter goods, if a higher motor output power is used from the beginning, it will consume more electricity, which will undoubtedly increase the cost of use and reduce energy efficiency.

[0004] To this end, we propose an intelligent material handling stacker structure to solve the above problems. Summary of the invention

[0015] Compared with the existing technology, the advantages of a stacker structure for intelligent material handling are:

[0016] Intelligent power regulation. During the cargo handling process, the stacker can realize intelligent adjustment of the servo motor output power for cargoes of different weights. Specifically, when the cargo is heavier, the piezoelectric pressure sensor is subjected to greater squeezing pressure, generating a stronger electrical signal to be fed back to the electromagnetic block. As the electrical signal increases, the magnetism of the electromagnetic block increases, repelling the corresponding permanent magnet block, so that the permanent magnet block drives the sliding end of the sliding rheostat to move a longer distance through the insulating block, thereby reducing the resistance value of the sliding rheostat connected to the servo motor circuit, and automatically increasing the output power of the servo motor to meet the handling needs of bulky cargo. When transporting lighter cargo, the resistance value of the sliding rheostat connected to the servo motor is slightly reduced, which slightly increases the output power of the servo motor, ensuring that the servo motor always maintains the output power most suitable for the current cargo weight. This not only avoids energy waste, but also improves handling efficiency, while reducing the risk of motor damage due to long-term overload operation.

[0017] Automatic lighting and protection. The stacker is equipped with an intelligent self-sensing protective lighting unit. When the external light becomes weak, the resistance of the photoresistor automatically increases, causing the contacts of the electromagnetic relay to automatically close, the lighting lamp and the electromagnetic plate to automatically power on and start. The electromagnetic plate is energized to generate a magnetic field to repel the permanent magnet plate, and the protective cover and the lighting lamp are automatically pushed out, providing automatic lighting for the staff in low-light environments to ensure the safety and accuracy of cargo transportation. When the external light is strong, the resistance of the photoresistor decreases, the contacts of the electromagnetic relay are automatically disconnected, and the lighting lamp is automatically turned off. At the same time, under the pull of the telescopic spring, the lighting lamp is automatically retracted for protection. This intelligent lighting system not only improves work efficiency, but also extends the service life of the lighting lamp and reduces maintenance costs.

[0018] Automatic cleaning and lubrication of the screw. The cleaning oiling ring on the fixed seat plays an important role in the operation of the stacker. The bristles on the cleaning oiling ring will automatically scrape and clean the corresponding screw to effectively remove impurities and dirt on the surface of the screw. When the screw needs to be lubricated for protection after a period of use, the fixed seat can be controlled by the drive unit to perform lifting operations. During this process, the metering pump draws a certain amount of lubricating oil from the oil tank and transports it to the cleaning oiling ring. The lubricating oil seeps out through the oil outlet and makes the bristles of the oiling brush stained with lubricating oil, thereby realizing automatic lubricating oil application to the screw. This automatic lubricating oil application method avoids the tediousness of traditional manual application, improves maintenance efficiency, extends the service life of the screw, and ensures the stable operation of the stacker's lifting mechanism.

The fixed column 73 is fixedly arranged on the sliding pressure block 72, and the upper end of the fixed column 73 is fixedly connected to the fork seat 6. The piezoelectric pressure sensor 75 is fixedly installed on the inner bottom surface of the buffer chamber 71, and the piezoelectric pressure sensor 75 is arranged opposite to the sliding pressure block 72. The buffer spring 74 can play a buffering and protective role on the fork seat 6, and avoid the hard squeezing of the fork seat 6 by the goods.

[0034] The support frame 2 is provided with a power self-adjusting unit 9 matched with each buffer pressure measuring unit 7, and the power self-adjusting unit 9 is electrically connected to the driving unit 4. The power self-adjusting unit 9 includes a control box 91, an electromagnetic block 92, a permanent magnet block 93 and a sliding rheostat 94.

Through the cooperation of the set photoresistor 106 and the electromagnetic relay 107, the lighting lamp 105 can be automatically started for lighting based on the changes in the light of the working environment, and when the external light is sufficient, the lighting lamp 105 can be automatically put away for protection, thereby realizing the intelligent opening and closing of the lighting system of the device, and when the lighting is not needed, the lighting lamp 105 can be put away for protection.

[0036] A plurality of plug blocks 22 are fixedly provided on the protective cover 104 , and slots 23 cooperating with the plug blocks 22 are provided on the protective chamber 101 . The cooperation between the plug blocks 22 and the slots 23 can ensure the tightness of the connection between the protective cover 104 and the protective chamber 101 .

[0037] The operating principle of the present invention is now described as follows:

[0038] First, in actual application, the entire device is accurately moved to the target position by driving the vehicle body 1. At this time, it is necessary to ensure that the two fork seats 6 of the device can be accurately inserted into the sockets of the bottom pallet of the cargo. This operation step lays the foundation for subsequent cargo handling.

[0039] Next, when the goods need to be lifted, the servo motor 41 is controlled to rotate forward. In this process, the pulley assembly 42 plays a key transmission coordination role. The two screws 3 rotate synchronously driven by the pulley assembly 42. This synchronization ensures the stability of the goods during the rising process. As the screw 3 rotates, the fixed seat 5 begins to drive the two fork seats 6 to move upward, thereby gradually lifting the goods off the ground. After the lifting of the goods is completed, the vehicle body 1 is driven again to move the device to the storage point. At the storage point, the driving unit 4 is used to accurately control the lifting and lowering of the goods, thereby achieving proper stacking of the goods at the storage point.

[0040] When the two forks 6 are lifting the goods, the intelligent adjustment function of the device begins to work. According to the different weights of the goods, the sliding pressure block 72 will apply different degrees of pressure to the corresponding piezoelectric pressure sensor 75. Specifically, when the goods are heavier, the squeezing force on the piezoelectric pressure sensor 75 will increase significantly. In this case, the piezoelectric pressure sensor 75 will generate a stronger electrical signal, which is fed back to the electromagnetic block 92. As the electrical signal increases, the current at the electromagnetic block 92 will also increase accordingly, thereby greatly improving the magnetism of the electromagnetic block 92. The strong magnetic electromagnetic block 92 will generate a repulsive force on the corresponding permanent magnet block 93. After being repelled by the repulsive force, the permanent magnet block 93 will drive the sliding variable resistor through the insulating block 13. The sliding end on the device 94 moves a farther distance. As the sliding end moves, the resistance of the sliding rheostat 94 connected to the servo motor 41 circuit becomes smaller. Due to the reduction in resistance, the output power of the servo motor 41 will automatically increase. Such an automatic adjustment mechanism can ensure that the device has sufficient power when carrying heavier goods to meet the needs of heavy object transportation. Similarly, when carrying lighter goods, the resistance of the sliding rheostat 94 connected to the servo motor 41 will decrease slightly. This small change in resistance causes the output power of the servo motor 41 to increase slightly, thereby allowing the servo motor 41 to always maintain the output power most suitable for the current weight of the goods, thereby avoiding energy waste and ensuring the efficiency of the transportation process.

[0041] During the cargo transportation process, the automatic control function of the lighting system provides great convenience for the staff. When the external light becomes weak, the resistance of the photoresistor 106 will automatically increase. This change will cause the working state of the electromagnetic relay 107 to change, and its contacts will automatically close. After the contacts are closed, the lighting lamp 105 and the electromagnetic plate 102 are automatically powered on and started. After the electromagnetic plate 102 is powered on, a magnetic field will be generated. The magnetic field produces a repulsive force on the corresponding permanent magnetic plate 103. Under the action of the repulsive force, the permanent magnetic plate 103 will move the protective cover 104 together with the lighting on it. The lamp 105 is automatically pushed out. At this time, the lamp 105 is exposed to the outside and can automatically provide lighting for the staff to ensure the safety and accuracy of cargo transportation in a low-light environment. When the external light is strong, the resistance of the photoresistor 106 will decrease. The reduction in resistance causes the contacts of the electromagnetic relay 107 to automatically disconnect, thereby causing the lamp 105 to automatically go out. At the same time, under the pulling force of the telescopic spring 14, the lamp 105 will be automatically retracted to play a protective role and prevent the lamp 105 from being damaged under unnecessary circumstances.

[0042] In addition, the device also embodies innovation in the maintenance of the screw 3. The cleaning oiling ring 16 on the fixed seat 5 in the device plays an important role during the lifting process. The coating brush 17 on the cleaning oiling ring 16 will automatically scrape and clean the corresponding screw 3, effectively removing impurities and dirt on the surface of the screw 3. When the screw 3 needs to be coated with lubricating oil for protection after being used for a period of time, the fixed seat 5 can be controlled by the drive unit 4 to perform lifting operations. During this process, a certain amount of lubricating oil is sucked from the oil storage tank 21 by a metering pump 20. The lubricating oil is transported to the two cleaning oiling rings 16 and seeps out through various oil outlets. The seeped lubricating oil causes the coating brush 17 to be contaminated with lubricating oil liquid, so that the screw 3 is automatically coated with lubricating oil during the lifting process of the fixed seat 5. This automatic method of applying lubricating oil avoids the tediousness of traditional manual application, improves maintenance efficiency, and extends the service life of the screw 3.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
