Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, in particular to a stacking and sorting mechanism. Background Art

[0002] In the packaging industry, box packaging accounts for over 90% of packaging applications. Loose boxes or medium bags are typically used for box loading, often loading materials vertically from the top down. Since packaging equipment often needs to meet high-speed packaging requirements, this places high demands on the packaging equipment's material handling mechanism. Existing packaging processes include manual box loading and case loading and automated in-line equipment. The stacking and handling mechanisms in automated in-line equipment primarily utilize drop-type upright boxes (bags), guided side-mounted boxes (bags), and rotary upright boxes (bags). Manual packaging is inefficient and prone to errors, while automated equipment presents challenges such as incomplete material handling, unstable material handling, and material damage. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a stacking material sorting mechanism in which the material boxes are constrained and controlled throughout the sorting process, the material packaging materials are not easily damaged, the structure is compact and the integration is high, and the stacking material sorting mechanism can be integrated into existing packaging equipment.

[0004] The stacking material sorting mechanism of the present invention, coupled with an external 90° flipping mechanism at the discharge port, enables the standing and arranging of box-like materials. The present invention clamps the box-like materials for feeding in a single file, which is then lifted to the stacking rack by a lifting cylinder, allowing the materials to stand in a single layer. The single layer of materials is then pushed to the flipping mechanism, where it is flipped 90° and laid flat for single-layer sorting. The entire sorting process maintains controlled constraints on the box-like materials, meeting the demands of high-speed sorting. The present invention does not include simple ejection and flipping mechanisms.

After the stacking rack, the flip support plate assembly holds the bottom row of material boxes, and the pressing assembly presses the top row of material boxes; during operation, the feed servo synchronous belt assembly runs to transport the box materials backward along the jacking cylinder assembly. After the jacking cylinder assembly is full of box materials, the jacking cylinder assembly lifts the entire row of box materials, and the box materials squeeze the flip support plate assembly to flip it up, so that the jacking cylinder assembly feeds the entire row of materials into the stacking rack as a whole. At the same time, the entire row of material boxes pushes the pressing assembly up, and the jacking cylinder assembly contracts. After reset, the flip support plate assembly pops up, and the box materials fall back onto the flip support plate assembly, so that the flip support plate assembly supports the bottom row of material boxes, the pressing assembly presses the top row of material boxes, and the stacking rack clamps the left and right sides of the entire row of material boxes.

[0033] Example 3

[0034] like Figures 7 to 9As shown, on the basis of Example 1 and Example 2, the jacking cylinder assembly 1 includes a mounting base plate 21, a jacking cylinder 22, a top plate 23 and a guide rod 24, the mounting base plate 21 is mounted on an adjustable bracket, and the adjustable bracket is mounted between the left side plate 8 and the right side plate 9. The adjustable bracket adjusts the position of the mounting base plate 21 so that the mounting base plate 21 is located between the left side plate 8 and the right side plate 9, the fixed end of the jacking cylinder 22 is mounted on the mounting base plate 21, and the top plate 23 is mounted on the piston rod of the jacking cylinder 22, and the top plate 23 is located below the middle of the two synchronous belts 18. The lower parts of the two guide rods 24 are slidably mounted on the mounting base plate 21, and the upper ends of the two guide rods 24 are connected to the top plate 23. The two guide rods 24 guide the top plate 23 to lift and lower; it also includes a cut-off cylinder 25 and a cut-off plate 26, the cut-off cylinder 25 is mounted on the middle front end of the left side plate 8 and the right side plate 9, the cut-off plate 26 is mounted on the top of the piston rod of the cut-off cylinder 25, and the objects on the top plate 23 When the material reaches the set quantity, the cutoff plate 26 extends into the entrance port of the feed servo synchronous belt assembly 5 to block the material box that has not entered the feed servo synchronous belt assembly 5 in front; the flip support plate assembly 7 includes a rotating bracket 27, a wedge-shaped support plate 28, and a spring 29.

Then, when the number of material boxes reaches a set value, the lifting cylinder 22 pushes the top plate 23 to lift the entire row of box-like materials. The box-like materials squeeze the two wedge-shaped support plates 28 to turn them inward, so that the top plate 23 feeds the entire row of materials into the fixed material rack 3 as a whole. 0 and the moving material rack 32, and then the entire row of material boxes pushes the two pressing plates 37 up, the top plate 23 shrinks and resets, the two wedge-shaped support plates 28 pop out, and the box materials fall back on the two wedge-shaped support plates 28, so that the two wedge-shaped support plates 28 support and hold the material boxes in the bottom row, and the two wedge-shaped support plates 28 press the material boxes in the top row, and the fixed material rack 30 and the moving material rack 32 clamp the left and right sides of the entire row of material boxes.
