Format Dispenser and Heat Sealer for Custom Bag Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack a single, multifunctional solution for dispensing and heat-sealing customized formats and bags of different sizes in the food sector, leading to inefficiencies in material usage and storage, as well as unnecessary waste and the need for multiple devices.
Innovation Solution
A compact, versatile machine that integrates a feeding subsystem, circulation subsystem, transverse heat-sealing and cutting subsystem, lateral heat-sealing subsystem, and control and actuation subsystem to alternately dispense, generate, and heat-seal formats and bags of various sizes, using rollers and heat-sealing elements to manage material tension and sealing without physically touching the product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple independent devices are used for dispensing, bag generation, and heat sealing, then each function can be performed reliably, but the number of devices increases and storage space is wasted
Solution Approach 1:
The patent combines three independent functions (format dispensing, bag generation, and heat sealing) into a single integrated machine. The feeding subsystem, circulation subsystem, heat-sealing subsystem, and control subsystem work together in one device, eliminating the need for separate dispensers, bag makers, and heat sealers while maintaining functional reliability through coordinated operation of all components.
Solution Approach 2:
The machine is designed with universal functionality to perform multiple operations: it can dispense formats of different sizes, generate bags from the dispensed material, and heat seal both formats and bags. The heat-sealing subsystem can selectively seal transverse or lateral edges based on the desired output, making the device adaptable to different production needs within a single unit.
2Ease of manufacture
If pre-cut material is supplied, then the supply process is simple, but the material does not adapt correctly to product size causing waste
Solution Approach 1:
The feeding subsystem is designed to dynamically adjust the dispensing of material based on the selected product size. The control subsystem receives user input for desired format dimensions and automatically controls the circulation subsystem to dispense the exact amount of material needed, preventing both shortage and excess that would lead to waste.
Solution Approach 2:
The machine allows parameter changes in material dispensing by enabling users to select different format sizes through the control subsystem. This adjusts the length and width parameters of the dispensed material to match the specific product requirements, eliminating the material waste associated with fixed pre-cut sizes.
3Area of stationary object
If a single consumable is used for all operations, then storage space is optimized, but the machine must handle multiple functions with one system
Solution Approach 1:
The machine internally segments its functionality into distinct subsystems (feeding, circulation, heat-sealing, control) that work together. Each subsystem is designed to handle specific tasks, but they are integrated into a unified system that processes a single consumable through multiple transformation stages, achieving both space efficiency and functional versatility.
Solution Approach 2:
The machine adds dimensional versatility by transforming the single consumable material through multiple dimensions: dispensing in different lengths (transverse dimension), creating different widths (lateral dimension), and forming three-dimensional bags. This multi-dimensional processing capability allows one system to handle diverse product requirements while maintaining a compact footprint.

AI summary
- A format dispenser, bag generator and heat sealer that makes it possible to dispense both formats and bags and, in both cases, in different customized sizes comprising: - A feeding subsystem (1) having an area for arranging spools (2). - A circulation subsystem (4) formed by rollers (5) that drag the material. - A transverse heat-sealing and cutting subsystem (6) that transversely cuts and heat-seals the material. - A lateral heat-sealing subsystem (7) when wanting to obtain a bag. - An external transverse output and heat-sealing subsystem (8). - A control and actuation subsystem (9). It makes it possible to alternately dispense formats and bags, allowing the user to select the desired format without unnecessary waste, and also has a final element that makes it possible to finish sealing the bags once they have been filled.
