[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] As Figures 1 to 11 shown, the four-station is a four-station frame assembly formed by connecting four station frames 1 side by side, and a hanging basket device 4 is connected to each station frame 1, and a vibrating disk 2 is provided at the bottom of each station frame 1; one end of an extended conveying device 5 is provided on one side of the four-station frame assembly, and the other end of the extended conveying device 5 is provided with a climbing conveying device 6; a station switching conveying device 3 is provided at the top of the four-station frame assembly.

[0035] The control end of the four-station soft landing system is connected to the four station frames 1, the vibrating disk 2, the station switching conveying device 3, the hanging basket device 4, the extended conveying device 5, and the climbing conveying device 6, and can control the work of each component at any time.

[0036] The station frame 1 is a rectangular three-dimensional frame structure, a switching conveying base 1-1 of the station switching conveying device 3 is connected to the top of the station frame 1, and a hanging basket connection support 1-2 is connected above the station frame 1.

[0037] At the rear of each station frame 1, i.e., on both sides of the input / output position where the material box is placed, safety light curtains and safety audible and visual alarms are installed. When the feeding and conveying work is carried out at the current station, the safety lights of its station frame will light up or show a red state (the light state and color can be adjusted as needed). When the safety light curtain detects that an object or a person enters the station frame, the lifting mechanism of this station stops working and gives an audible and visual alarm (this alarm can be reset to the normal working process after being triggered), preventing the operator from accidentally transporting the working material box away and protecting the safety of the workers. When the material is full, the safety light of this station will turn green or go out. After the operator sees it, the full material box can be transported out, and at the same time, an empty material box is replaced.

[0038] The vibrating disk 2 is designed to spread the materials in the material box by jittering / vibrating, preventing the materials from being randomly piled up in the material box and affecting the filling rate of the materials.

[0039] The vibration of the vibrating disk 2 is controlled by parameter settings, which are set and displayed on the control screen of the soft landing system. When the materials (i.e., preforms) are loaded into the corresponding capacity of the material box, the vibrating disk 2 starts to vibrate. For example, it can be set to vibrate for 5 s when the material box is filled to 2 / 5, vibrate for 10 s when filled to 3 / 5, and keep vibrating until filled when filled to 4 / 5.

[0040] The station switching and conveying device 3 includes a support base, a conveyor belt mechanism, a translation cylinder, a cable drag wheel connection bracket, a cable drag wheel, a guide wheel, and a translation roller.

And the rims of the translation roller 3-2 and the guide wheel 3-10 respectively abut against the bottom and side of the conveyor belt mechanism base 3-3.

[0043] Multiple sensors are installed on the station-switching conveying device 3, and during operation, information such as its position and conveying status is transmitted to the control terminal at any time, so that the control terminal can perform switching operations on the position and conveying direction.

[0044] The general mode of the station-switching conveying device 3 is to first convey the first station and the second station. After the first station and the second station are filled, the third station and the fourth station are then conveyed.

The upper part of the hanging basket frame 4-3 is in a rectangular frame structure, and the lower part of the hanging basket frame 4-3 is in an inverted triangular frame structure. The left hanging basket bucket frame 4-4 and the right hanging basket bucket frame 4-5 are respectively connected to the left and right sides of the lower part of the hanging basket frame 4-3. The tops of the left hanging basket bucket frame 4-4 and the right hanging basket bucket frame 4-5 are respectively connected to the bucket switch cylinder assembly 4-6. A sonar sensor 4-7 is provided between the left hanging basket bucket frame 4-4 and the right hanging basket bucket frame 4-5, and the sonar sensor 4-7 is connected to the lower part of the hanging basket frame 4-3 through a sensor support.

[0046] Guide rods 4-8 are respectively provided on the left and right sides of the lifting cylinder 4-1. The tops of the left and right guide rods 4-8 are connected through a connecting plate, and the bottoms of the left and right guide rods 4-8 are connected to the hanging basket support 4-2.

In this way, no matter how the position of the conveyor belt mechanism 3-4 on the station switching conveyor device 3 changes, it will not affect the feeding process.

[0050] The climbing conveying device 6 includes a second moving bracket, a second belt conveying bracket, and a second belt conveyor. The second belt conveying bracket 6-2 is an L-shaped frame structure.

Empty material boxes are respectively loaded at the bottoms of the four station frames 1, and the conveyor belt mechanism 3-4 of the current station switching conveyor device 3 is located between the first station and the third station; S2. The climbing conveying device 6 starts to transport materials, and the materials are transported to the four-station frame assembly through the extended conveying device 5; S3. When the materials are transported from the end of the extended conveying device 5 to the station switching conveyor device 3, the conveyor belt servo motor 3-8 on the station switching conveyor device 3 controls the conveyor belt mechanism 3-4 to rotate counterclockwise, and transports the materials into the hanging basket frame of the first station. The lifting cylinder of the hanging basket device controls the hanging basket frame to place the materials into the empty material box of the first station; S4. When the material box at the first station is full of materials, the conveyor belt servo motor 3-8 controls the conveyor belt mechanism 3-4 to stop transporting. When the material box at the first station is collecting materials, the vibrating disk at its bottom will vibrate according to requirements until the material box is full of materials and then stops vibrating; S5. The translation cylinder 3-7 pushes the conveyor belt mechanism 3-4 to make the conveyor belt mechanism 3-4 located between the second station and the fourth station; S6. After reaching the designated position, the conveyor belt servo motor 3-8 on the station switching conveyor device 3 controls the conveyor belt mechanism 3-4 to rotate counterclockwise, and transports the materials into the hanging basket frame of the second station. The lifting cylinder of the hanging basket device controls the hanging basket frame to place the materials into the empty material box of the second station; S7. When the material box at the second station is full of materials, the conveyor belt servo motor 3-8 controls the conveyor belt mechanism 3-4 to stop conveying. When the material box at the second station is collecting materials, the vibrating disk at its bottom will vibrate according to requirements until the material box is full of materials and then stops vibrating. S8. The conveyor belt servo motor 3-8 on the station switching conveyor device 3 controls the conveyor belt mechanism 3-4 to rotate clockwise, conveying the materials into the hanging basket frame at the fourth station.
