[0022] Please refer to Figures 1-3, the present utility model provides a technical solution: a vertical cotton bale palletizing device. The palletizing device includes a roller support 1 arranged at the bottom; above the roller support 1, there is a bale clamp 4 used to grab the cotton bale 3; the end of the bale clamp 4 is actuated by a clamping cylinder 5 arranged to implement the clamping operation; the bale clamp 4 is connected to one end of a lifting arm 6, and a slider 10 is arranged at the other end of the lifting arm 6; the slider 10 can slide up and down along a linear guide rail 11 arranged on a column 12; the upper part of the slider 10 is connected to a lifting motor 7 by a chain 8; the other end of the chain 8 is connected to a counterweight 9; a slewing bearing 14 is arranged at the lower part of the column 12; the column 12 is powered by a steering motor 13 arranged, and rotates on a base 15 arranged at the bottom by using the slewing bearing 14.

[0023] The roller support 1 is of a frame structure and is directly connected to the cotton bale conveyor belt. A column 12 is arranged on the side of the roller support 1, and the column 12 is used to support the lifting arm 6. A clamping cylinder 5 for controlling the bale clamp 4 to clamp the cotton bale 3 is arranged at the front end of the lifting arm 6. The clamping cylinder 5 is a pneumatic cylinder. When the clamping cylinder 5 shortens, the bale clamp 4 opens, and conversely, when the clamping cylinder 5 extends, the bale clamp 4 closes to clamp the cotton bale 3. A linear guide rail 11 is arranged on the column 12, a slider 10 is arranged on the linear guide rail 11, and the slider 10 is provided with a groove that can be engaged with the linear guide rail 11 to ensure its sliding on the linear guide rail 11. And the slider 10 is powered by the pulling of the chain 8 and the lifting motor 7 at the top of the column, so that it can drive the lifting arm 6 to lift and lower. And in order to reduce the impact force when the lifting motor 7 starts and stops, a counterweight 9 is arranged at the other end of the chain 8. The rotation of the column 12 depends on the slewing bearing 14 and the steering motor 13 at the lower part of the column 12. The cotton bale 3 is palletized and transported out by rotating.

[0024] An optoelectronic switch 2 is arranged on the upper part of the roller support 1. After the optoelectronic switch 2 senses the arrival of the cotton bale 3, it can control the clamping cylinder 5 to start and clamp the cotton bale 3.

[0025] A rail 17 is arranged on one side of the base 15; a transport vehicle 16 is arranged on the rail 17. A transport motor 18 for providing power for the transport vehicle 16 to slide along the rail 17 is arranged on the transport vehicle 16; an electric push rod 19 is also arranged on the transport vehicle 16; a tray 20 is arranged on the upper part of the transport vehicle 16. A rail 17 is arranged on the side of the column 12, and a liftable transport vehicle 16 and a tray 20 are arranged thereon to palletize and transport the cotton bale 3. Among them, the transport motor 18 controls the movement of the transport vehicle 16 on the rail 17, and the electric push rod 19 controls the lifting of the tray 20.

[0026] Working process: The bale of cotton 3 is driven by the conveyor belt of the baling machine to the roller support 1. When there is a signal from the photoelectric switch 2, at position A, the clamping cylinder 5 acts to make the clamp 4 clamp the bale of cotton 3. The lifting motor 7 drives the chain 8 to pull the lifting arm 6 to lift. At the same time, the steering motor 13 drives the column 12 to rotate to the bale stacking position B. After the lifting arm 6 descends to the predetermined position, the clamping cylinder 5 pulls the clamp 4 to release the bale of cotton 3. The lifting arm 6 returns to position B. The steering motor 13 drives the column 12 to rotate back, and the lifting arm 6 falls to position A, waiting for the next bale of cotton 3.

[0027] When the required number of bales of cotton 3 is reached, the electric push rod 19 installed on the transport vehicle 16 pushes the tray 20 to lift the stacked bales of cotton. At this time, the bales of cotton are separated from the track 17 by a certain distance C. The transport motor 18 drives the transport vehicle 16 to send the bales of cotton 3 to the designated position, and then the electric push rod 19 pulls the tray 20 to descend, placing the bales of cotton on the track 17. At this time, the plane of the tray 20 is lower than the track 17 by a distance D. The transport motor 18 drives the transport vehicle 16 to return to the bale stacking position. When the required number of bales of cotton 3 is reached, the transport vehicle 16 continues the previous operation.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
