[0001] The invention relates to a packaging machine, in particular to a packaging box longitudinal stacking mechanism for integrated stacking of a plurality of packaging boxes, which is applied to a transparent film wrapping machine. Background Art

[0002] At present, the cartoning machine is a device that integrates materials (blister tablets), instructions (paper tablet instructions), paper boxes, etc. into small packaging boxes, and then integrates multiple small packaging boxes and repackages them into medium packaging boxes (i.e. box-in-box). It involves the repackaging of various types of items such as food, medicine, and cosmetics, and has a large market demand space. It needs to focus on the design of multiple processes such as waste rejection, touch flipping (from horizontal flipping to vertical placement), multiple small box transfer and pushing, and stacking storage. The transparent film wrapping machine (transparent film strapping machine) is a device that is connected to the cartoning machine and wraps multiple packaging boxes with transparent film. Because the packaging boxes block the material and are time-consuming, the packaging speed of the equipment is limited. Summary of the invention

The box feeding support plate 11, the rotating card box strip 12, and the floating pressure block 13 (one each at the front and rear) are sequentially installed. The floating pressure block 13 is installed on the pressure block guide rod 14. The top box lifting power source 15 (a top box lifting motor) is installed under the stacking machine frame 18. The top box lifting power source 15 is connected to the top box lifting plate 16 through the top box lifting intermediate transmission component 20. The top box strip 17 (one each at the front and rear) is installed on the top box lifting plate 16. The top box strip 17 is located on the side of the box feeding support plate 11. The top box lifting plate 16 is installed under the stacking machine frame 18 through the top box lifting plate mounting seat 37. A packaging box detection switch 19 (detecting whether the packaging box to be stacked is in place, located below the rotating card box strip 12) is installed on the stacking machine frame 18 and between the stacking side plates 10.

[0016] The rotating card box strip 12 is connected to the card box rotating shaft 21 through the card box swing arm 29. The card box rotating shaft 21 is installed on the stacking machine frame 18. A limited reset mainboard 22 is installed on the stacking machine frame 18 and on the outer side of the stacking side plate 10. A reset spring 23 (and a limit screw 24, one reset spring on each side and the limit screw in the middle) is installed on the limited reset mainboard 22. The reset spring 23 (and the limit screw 24) is connected to the rotating card box strip 12. The top box lifting intermediate transmission component 20 includes a connected top box driving wheel 25, a top box synchronous belt 26, and a top box driven wheel 27 (installed under the stacking machine frame 18). The top box driving wheel 25 is connected to the top box lifting power source 15. A synchronous belt clamp 28 is installed on the top box synchronous belt 26. The synchronous belt clamp 28 is connected to the top box lifting plate 16.

[0017] like Figure 1 , Figure 5 , Figure 6As shown, a material handling propulsion mechanism 3 is installed on the archway 2 and above the stacking side plate 10. The material handling propulsion mechanism 3 includes a moving cross plate 30 installed on the archway 2. The moving cross plate 30 is connected to a propulsion power source 32 (a propulsion motor) through a propulsion intermediate transmission assembly 31 (including a connected propulsion driving wheel, a propulsion synchronous belt, a propulsion clamping plate, a propulsion driven wheel, etc.). A push rod 33 (the push rod moves between the stacking side plates 10 or moves to the outer position of the stacking side plates 10) is installed under the moving cross plate 30. The push rod 33 is connected to a displacement power source 34 (a displacement cylinder). The moving cross plate 30 is installed on a material handling guide rail 35, and the material handling guide rail 35 is installed on the archway 2 through a guide rail mounting plate 36.

[0018] The longitudinal stacking type box collection material sorting, flipping and pushing device used in the present invention is also equipped with a rotating feeding mechanism 5 on the platform frame 1 and at the side of the material sorting and pushing mechanism 3 (subsequent process, right position). A material storage platform 4 is installed on the platform frame 1 and between the stacking side plate 10 and the rotating feeding mechanism 5, a main pushing mechanism 6 is installed on the platform frame 1 and at the side of the rotating feeding mechanism 5 (left position), and a feeding conveying assembly 7 is installed on the platform frame 1 and at the docking position with the stacking frame 18 (position between the stacking side plates). The stacking frame 18, the stacking side plate 10, the box feeding support plate 11, the rotating card box strip 12, the floating pressure block 13, the pressure block guide rod 14, the top box lifting power source 15, the top box lifting intermediate transmission assembly 20, the top box lifting plate 16, the top box strip 17, the packaging box detection switch 19, etc. constitute the packaging box longitudinal stacking mechanism 8.

[0019] The working principle of the present invention is as follows: the transversely placed packaging boxes that have completed the packaging of materials and instructions are conveyed by the feed conveying component 7, enter the position between the stacking side plates 10 of the packaging box longitudinal stacking mechanism 8 and are supported by the two sides of the box feeding support plate 11 (it can be a row of packaging boxes in multiple columns). At the same time, the top box lifting power source 15 works to drive the top box lifting plate 16 through the top box lifting intermediate transmission component 20, so that the top box bar 17 pushes the top box upward, and the packaging box touches the rotating card box bar 12 upward, so that the rotating card box bar shrinks around the card box rotating axis 21 through the card box swing arm 29, and the packaging box continues to move upward to slightly above the rotating card box bar and the rotating card box bar returns to its original position through the reset spring 23, and then the rotating card box bar supports the packaging box and is pressed by the floating pressure block 13 to automatically position it, thereby completing the lifting of the transversely placed packaging boxes one by one and the longitudinal stacking and stacking of multiple columns and rows of packaging boxes. Afterwards, the propulsion power source 32 of the material sorting and propulsion mechanism 3 works to drive the moving cross plate 30 by pushing the intermediate transmission component 31, and the push rod 33 pushes the longitudinally stacked packaging boxes along the rotating card box strip between the stacking side plates and into the material storage platform 4.

[0020] Then, the push rod 33 of the material sorting and pushing mechanism 3 pushes the longitudinally stacked packaging boxes through the material storage platform 4 into the rotary feeding mechanism 5. After the pushing of the rotary feeding mechanism is completed, the push rod is controlled by the shifting power source 34 to shift to the periphery of the material storage platform (or the stacking side plate) and goes back to the entrance side of the stacking side plate through the pushing power source 32. The work of the push rod forms a rectangular loop path, which effectively avoids the interference between the push rod return and the packaging box.

[0021] The present invention adopts a multi-row and multi-column lifting and stacking structure to sort the packaging boxes at the maximum speed possible, which is conducive to matching the output of the front-end cartoning machine. The number of boxes and packages is controlled by a program, and the stacking structure is adjustable and suitable for packaging boxes of different specifications. The packaging box sorting and horizontal pushing is increased, with adjustable stroke, rapid action, and precise positioning. It is used to push the stacked packaging boxes to the storage platform, and according to the specifications of the packaging boxes, the packaging boxes on the storage platform workstation are pushed into the rotary feeding mechanism one by one in a single row by a segmented small push method.
