Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods and devices for forming packaging sleeves in filling machines require complex and space-consuming forming stations due to the handling of packaging sleeves that are open at both ends, necessitating significant space and complexity for unfolding and shaping.
Innovation Solution
A method and device utilizing a forming station with at least three adjustable forming parts that unfold and shape packaging sleeves by holding them in an open position, allowing for efficient transfer and formation without the need for complex movements, using a feeding and discharge device that forms part of the forming station to facilitate space-saving operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If packaging jackets are formed open on both sides for continuous production, then productivity is improved, but the packaging bodies cannot be stacked stably during transport and storage
Solution Approach 1:
The packaging jacket is formed with a preliminary open side edge structure during continuous production that enables subsequent folding to create stable packaging bodies. The open side edge is prepared in advance with appropriate geometry and flexibility to allow folding operations that will create stable stacked configurations.
Solution Approach 2:
The packaging jacket transitions from a flexible open state during production and handling to a stable folded state during stacking. The material properties and structural design allow the jacket to be dynamic during formation and transport, then become stable when folded into the final packaging body configuration for stacking.
2Device complexity
If packaging bodies are formed by folding side edges of packaging jackets, then device complexity is reduced, but manufacturing precision is worsened due to difficulty in achieving consistent fold configurations
Solution Approach 1:
The patent optimizes parameters such as the angle and geometry of open side edges, material flexibility, and folding dimensions to enable consistent fold configurations. By carefully controlling these parameters, the folding process achieves sufficient precision without requiring complex forming devices.
Solution Approach 2:
The packaging jacket structure is designed to self-fold into the correct configuration through its geometric design and material properties. The open side edges are shaped and positioned so that folding occurs naturally along predetermined lines, reducing the need for complex external forming equipment while maintaining consistent results.
3Loss of time
If packaging jackets are formed open on both sides for continuous production, then loss of time is reduced, but reliability is worsened due to instability during transport and storage
Solution Approach 1:
The packaging jacket is prepared with preliminary structural features during high-speed continuous production that ensure stability is achieved upon folding. The open side edges are formed with specific geometries that predispose the material to fold into stable configurations, ensuring reliability during transport and storage while maintaining production efficiency.

AI summary
Described and illustrated is a method for the simple and space-saving shaping of packaging jackets (51) for the production of filled packages, in which: - packaging jackets (51) folded flat around at least two folding edges (54) extending in the longitudinal direction of the packaging jackets (51) are transferred from a feed device (55) to a shaping station (56) comprising at least three shaping parts (57-60); - the transferred packaging jackets (51) are held in an open position of the shaping station (56) between at least two shaping parts (57, 58); - packaging jackets (51) held between the at least two shaping parts (57, 58) are folded up and shaped by an adjusting of the at least three shaping parts (57-60) into a closed position of the shaping station (56); - the folded-up and shaped packaging jackets (51) are discharged one after the other from the shaping station (56) by a discharge apparatus (66) and; - the feed device (55) and/or the discharge apparatus (66) forms a shaping part (59, 60) of the shaping station (56) for shaping the packaging jackets (51).
