Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wrapping machines for confectionery products face limitations in operating speed when applying bands, particularly for small batches, leading to reduced productivity.
Innovation Solution
A method and apparatus that utilize stepwise feeding, lifting of rear flaps using suction means, and counter-rotating knives to apply bands on a wrapping material strip, allowing high-speed operation and precise cutting with a protruding rear flap for gluing, enhancing productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pre-cut bands are fed from dedicated stores using gripping means, then the wrapping process can be completed, but the operating speed is limited and productivity is reduced
Solution Approach 1:
The patent merges the band application process with the wrapping material feeding process. Instead of separate gripping means for pre-cut bands, the band is applied continuously onto the wrapping material strip during the stepwise feeding operation, combining two functions into one integrated process that increases operating speed while maintaining manageable device complexity
Solution Approach 2:
The band is applied onto the wrapping material strip in advance during the stepwise feeding process, before the actual wrapping operation. This preliminary application allows the band to be positioned and prepared simultaneously with the wrapping material, eliminating sequential operations and improving overall operating speed
2Adaptability or versatility
If bands are obtained from strip material unwound from reels and cut into individual portions, then large production quantities can be handled, but the process cannot accommodate limited batches with specific requests
Solution Approach 1:
The patent implements a dynamic system where the band application process can adapt to different production scenarios. The stepwise feeding mechanism allows the system to operate at high speed for large batches while maintaining the ability to handle limited batches with specific requests, providing operational flexibility without sacrificing productivity
Solution Approach 2:
The apparatus is designed to perform multiple functions: it can handle both large production quantities and limited batches with specific requests using the same band application mechanism. The system universally applies bands onto wrapping material strips regardless of batch size, eliminating the need for different apparatus configurations
3Manufacturing precision
If the rear flap of the band is lifted with suction means before cutting, then the band can be properly positioned for gluing, but the apparatus complexity increases
Solution Approach 1:
The patent uses suction means (pneumatic mechanism) to lift and position the rear flap of the band before cutting. This pneumatic action provides precise control over the flap positioning, ensuring accurate alignment for subsequent gluing operations while adding only a single functional module to the apparatus
Solution Approach 2:
The rear flap is lifted and positioned in advance using suction means before the cutting operation occurs. This preliminary positioning ensures that when the wrapping material strip is cut to define the single wrapping sheet, the band is already correctly positioned for the gluing step, improving manufacturing precision

AI summary
The method for the application of a band on the wrapper of confectionery products and the like in a wrapping machine entails feeding a wrapping material strip (2) with a stepwise feeding and applying individual bands (3) in succession on the wrapping material strip (2) being fed in a stepwise manner. Then, a rear flap of said individual bands (3) applied on the wrapping material strip (2) is lifted and the wrapping material strip (2) is cut, in a suitable phase relationship, to define a single wrapping sheet (21), so that the rear flap of the band (3) protrudes for a free stretch with respect to the rear edge of the wrapping sheet (21) defined by the cutting line of the wrapping material strip (2).
