[0017] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0018] The two linear motors 4 alternately drive the two slides 2 to slide on the cloth-loading plate 11, drive the two supporting assemblies 3 to move alternately to align with the back plate 12, thereby connecting the two slides 2 to the cartons 7 at the unloading port of the conveying mechanism 6.

[0019] The automatic carton packaging device also includes two automatic strapping machines 5, which are respectively arranged on both sides of the conveying mechanism 6. The feed ports of the two automatic strapping machines 5 are arranged facing the base 1. The automatic strapping machines 5 are mature strapping and packaging equipment at this stage. The automatic strapping machines 5 use PET strapping tape as the packaging consumables. The model of the automatic strapping machines 5 is selected according to the production needs of the specific production line.

[0020] The supporting assembly 3 includes a bending plate 31, a pushing plate 32 and a ball screw assembly 33. The bending plate 31 is bent at a right angle, and the ball screw assembly 33 is fixedly embedded in the horizontal side of the bending plate 31. The pushing plate 32 is arranged parallel to the vertical side of the bending plate 31. The lower end of the pushing plate 32 is fixedly connected to the nut of the ball screw assembly 33. The ball screw assembly 33 is driven by a stepper motor to perform forward and reverse operations, that is, to drive the pushing plate 32 to push and return to slide. The ball screw assembly 33 is driven by the stepper motor to operate forward, driving the pushing plate 32 to slide away from the vertical side of the bending plate 31, pushing the stacked cartons 7 to the automatic strapping machine 5. On the contrary, when the ball screw assembly 33 is driven by the stepper motor to operate in the reverse direction, the pushing plate 32 returns to the front facade that is in contact with the vertical side of the bending plate 31.

[0021] The supporting assembly 3 is hingedly mounted on the top surface of the skateboard 2, and a hinge seat is provided at the rear edge of the top surface of the skateboard 2. The bent plate 31 is hinged to the hinge seat at the bending corner, and the bent plate 31 can be rotated on the skateboard 2 with the hinge axis as the base point for position adjustment. An embedding groove is provided at the front edge of the top surface of the skateboard 2, and an air pump 21 and an air bag 22 are embedded in the embedding groove. The air bag 22 is sealed on the air nozzle of the air pump 21. When the bent plate 31 is in a horizontal posture, the air bag 22 maintains a vacuum and shrinks in the embedding groove. The bent plate 31 needs to be moved to When the folding plate 31 is lifted up, the air pump 21 is operated to inflate the airbag 22. When the airbag 22 is full, the horizontal side of the bending plate 31 is pushed upward, and the bending plate 31 is pushed to rotate so that the vertical side is against the stand 15. When the bending plate 31 needs to be adjusted back to a horizontal posture, the air pump 21 is started to discharge the air in the airbag 22, and the airbag 22 is retracted into the embedding groove. The pushing force at the bottom of the bending plate 31 is cancelled, and the bending plate 31 is returned to a horizontal posture. When the bending plate 31 is in a horizontal posture, the top surface of the horizontal side of the bending plate 31 is flush with the working surface of the automatic strapping machine 5.

[0022] An intercepting frame 14 is vertically arranged at the front edge of the base 1 toward the conveying mechanism 6. The intercepting frame 14 is located on the same central axis as the vertical frame 15 and the back plate 12. The setting of the intercepting frame 14 effectively prevents the carton 7 from slipping when it falls onto the supporting assembly 3.

[0023] A frame 61 is set at the discharge port of the conveying mechanism 6, and the frame 61 is arranged across the conveying line of the conveying mechanism 6. A counter is fixedly set on the lower surface of the frame 61 facing the conveying mechanism 6. The counter is a conveyor belt counter, which is a mature existing technology at this stage and can be directly selected according to working conditions. The counter is electrically connected with the stepping electronics of the linear motor 4, the air pump 21 and the ball screw assembly 33 through the control circuit. The counter counts the cartons 7 conveyed on the conveying mechanism 6. When the count value reaches a preset value, multiple components are coordinated and controlled to operate in a coordinated manner, thereby realizing automatic packaging of the cartons 7.

[0024] Working principle: The device is installed as a whole in the carton production line and set at the carton packaging process. Two automatic strapping machines 5 are arranged on both sides of the unloading port of the conveying mechanism 6, and the central axis of the base 1 is arranged opposite to the unloading port of the conveying mechanism 6.

[0025] The initial state of the device is that one slide plate 2 is located at the middle position of the base 1 facing the unloading port of the conveying mechanism 6, the air bag 22 on the slide plate 2 is in a full state, and the pushing and supporting component 3 is in a backward posture against the vertical frame 15, which is convenient for supporting the falling carton 7 head-on. The other slide plate 2 is located at one end of the base 1 waiting in the waiting area, and the supporting component 3 on this slide plate 2 is in an upright posture to prevent collision during subsequent movement.

[0026] When the device is running, the conveying mechanism 6 transports the flat-plate cartons 7 that have completed the upstream processing steps to the packaging step and drops them one by one onto the supporting assembly 3. The counter installed on the frame 61 counts the cartons 7 that pass through. When the cumulative number of cartons 7 reaches the preset rated number, the counter feeds back the signal to the control circuit. The control circuit first controls the air pump 21 to discharge the air in the airbag 22 to restore the supporting assembly 3 to an upright position (because the airbag 22 is a fixed volume structure, the power of the air pump 21 is determined, and the pumping time can be controlled). Then the control circuit controls the linear motor 4 connected to the slide 2 to operate and push the slide 2 to the base 1. One end is aligned with an automatic strapping machine 5, and then the control circuit controls the ball screw assembly 33 to operate, so that the pushing plate 32 slides on the bending plate 31, and pushes the stacked cartons 7 to the working table of the automatic strapping machine 5. When the sensor of the automatic strapping machine 5 detects that the carton 7 is pushed into place, the carton 7 is strapped; while the slide 2 for transporting the carton 7 moves, another linear motor 4 moves synchronously to the middle position of the base 1 under the control of the control circuit. When it moves into place, the air pump 21 on this slide 2 inflates the airbag 22, and the airbag 22 pushes the supporting assembly 3 backward to welcome the carton 7 transported by the conveying mechanism 6.

[0027] During the packaging process, the two slides 2 alternately shift to allow the corresponding support assembly 3 to complete the support of the carton 7. During transportation, the carton 7 is strapped by the corresponding automatic strapping machine 5. The counter is reset to zero each time it counts down. The control circuit's control function is conventional and can be applied according to specific working conditions.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
