Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to an automatic tray sorting and tray loading device. Background Technology

[0002] In the production of liquid filling, food, and pharmaceutical packaging, bottles are typically output vertically after filling and labeling processes, requiring them to be orderly loaded into pallets for subsequent transportation or storage. Traditional palletizing methods rely heavily on manual operation, removing bottles from the conveyor line and placing them into stacked pallets. This is not only labor-intensive and inefficient, but also prone to bottle breakage or misalignment due to improper handling, affecting product consistency and production safety.

[0003] With the development of automation technology, some production lines have begun to use robotic arms or simple conveying devices for automated pallet loading. However, existing equipment generally suffers from insufficient automation and poor process coordination. For example, pallets are mostly stacked, lacking efficient automatic sorting and individual conveying mechanisms, still requiring manual intervention for loading. Simultaneously, most equipment cannot automatically flip vertically output bottles, resulting in mismatched bottle loading postures and affecting loading accuracy and stability. Furthermore, the lack of reliable clamping or positioning structures after bottles are loaded makes them prone to tipping or shifting during transportation.

[0004] Therefore, there is an urgent need for a fully automatic tray sorting and tray loading device that integrates automatic tray sorting, bottle flipping, precise tray loading, and bottle pressing and fixing, so as to realize continuous and intelligent operation from bottle supply to tray loading, improve overall production efficiency, reduce breakage rate, and ensure the consistency of product packaging quality.
