[0018] The lifting structure is composed of a lifting platform 16, a wire rope pulley 19, a wire rope 20 and a synchronous motor 21. The lifting platform 16 is a rectangular frame structure, and the lifting platform 16 is arranged parallel to the top of the square frame. The four corners of the lifting platform 16 are respectively integrally formed with lifting platform sliders 17. The lifting platform 16 is slidably connected to the lifting platform track 18 through the lifting platform slider 17 to ensure the stability of the lifting platform when it moves up and down. The two sides of the lifting platform 16 are respectively fixedly connected to one end of the wire rope 20, and the other end of the wire rope 20 is fixed to the output end of the synchronous motor 21 fixedly arranged on the transition belt 1. Wire rope pulleys 19 are respectively arranged on both sides of the transition belt 1, and a section of the wire rope 20 is located on the wire rope pulley 19;

[0019] The stacking structure is composed of a pushing part, a transition part and a concentrated part, wherein the pushing part includes a power roller group mechanism 5, a power roller mechanism 22, a width and narrow baffle mechanism 9, a roller group bracket movable connecting shaft 14, a stacking plate and a stacking plate adjusting mechanism. The power roller group mechanism 5 is composed of a roller and a power roller motor. The stacking plate is hinged to the front end support leg of the lifting platform 16 through the roller group bracket movable connecting shaft 14. The stacking plate structure is a rectangular frame with rollers equidistantly distributed in sequence and movably installed front and back. The power roller mechanism 22 includes a cross-shaped roller, which is movably installed on the lifting platform 16, and one end of which is connected to the output end of the power roller motor.

The power roller motor, the power roller motor, the width and narrow baffle motor, the lifting motor 11 and the power roller mechanism 22 are all driven by a PLC controller and a signal sensor, and the motion control is realized through PLC programming to realize unmanned operation.

[0020] The stacking plates of the pushing part, transition part and concentrated part are arranged in a flush correspondence from head to tail to ensure that the movement of the packages is not subject to any resistance during the package arrangement operation. The stacking plates of the pushing part, transition part and concentrated part are each in two groups and are arranged symmetrically on the left and right to provide uniform force support for the packages on the stacking plates.

[0021] Among them, the positions of the transition belt 1, the power roller group mechanism 5 and the stacking plate are arranged in a corresponding and flush manner to ensure that when arranging packages, the packages passing through the transition belt 1 can be transferred to the power roller group mechanism 5 without resistance for subsequent package arranging operations. The transition belt 1 can be driven by a motor.

[0022] The stacking operation principle of this embodiment is as follows:

[0023] S1. First, the walking mechanism motor in the walking mechanism 2 is started through PLC programming control (completed through PLC controller and signal sensor, which belongs to the prior art and is not the object of protection of this technical solution, so it is not described in detail). The walking mechanism 2 drives the entire gantry to reach the designated stacking operation point (which can be arbitrarily adjusted according to the actual stacking operation), and the PLC programming controls the walking mechanism 2 to stop operating;

[0024] S2, the synchronous motor 21 is started by PLC programming control, and the overall lifting platform 16 is controlled by winding or loosening the wire rope 20 (the winding or loosening of the wire rope 20 is determined according to the height of the first stacking of the bagged objects during the adjustment process) to the specified stacking operation height, and the synchronous motor 21 is stopped by PLC programming control;

[0025] S3, by moving the transition belt 1 at a certain height to a position flush with the power roller group mechanism 5 at a corresponding height, the transition belt 1 is manually pushed;

[0026] S4, the power roller motor in the power roller group mechanism 5, the power roller motor in the power roller mechanism 22 and the width and narrow baffle motor 15 are started by PLC programming control, the width of the baffle is adjusted to the specified width, and the PLC programming control issues an instruction to stop the width and narrow baffle motor 15 (the width of the baffle is adjusted according to the specifications of the required bagged objects, and is used to neatly arrange the bags on the stacking board);

[0027] S5, manually turn on the control motor of the transition belt 1 to make the transition belt 1 run, move the bagged objects onto the transition belt 1, and the bagged objects are transferred to the power roller group mechanism 5 under the drive of the transition belt 1. Under the drive of the power roller group mechanism 5 and the power roller mechanism 22, the bagged objects pass through the unpowered roller group mechanism 8, and the bagged objects sequentially pass through the pushing part and the transition part to enter the concentrated part (i.e., the end of the stacking board) for arrangement. When the entire stacking board has stacked the bagged objects according to the set number (the number of stacking of one layer of the expected bagged objects), the stacking board bag arrangement operation is completed, and the PLC programming control issues an instruction, and the power roller motor in the power roller group mechanism 5 and the power roller motor in the power roller mechanism 22 stop operating;

[0028] S6, PLC programming controls the lifting motor 11 to start, driving the lifting screw 4, so that the slider 12 connected to the connecting rod 6 moves downward in the slide 13, driving the connecting rod 6 to move downward, so that the stacking plates on both sides open downward, and the bags on the stacking plates fall on the designated stacking positions. One row of stacking operations is completed, the stacking plates are reset, and the second layer of stacking operations is prepared (the stacking plate reset action is to control the lifting motor 11 to run in the reverse direction through PLC programming, and the stacking plates will be reset to repeat the stacking plate bag arranging operation).

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
