Helical Wire Bending Device for Pulp Tying Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The disposal of leftover wire in tying machines used in pulp production is inefficient, requiring manual removal and occupying storage space, as existing methods do not automate the process effectively.
Innovation Solution
A device with a bending mechanism, comprising rolls and a movable bending element, that can retract from the operational path during normal use and move into position to wind leftover wire into a compact helical or spiral shape for easy disposal, reducing labor and storage needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual removal of leftover wire is used, then labor time is consumed, but wire disposal is simple
Solution Approach 1:
The bending device automatically detects and processes leftover wire without operator intervention. The device moves into position when wire supply is low and performs bending/coiling operations autonomously, then returns to idle position, making the system self-servicing for wire disposal tasks
Solution Approach 2:
The bending device is designed with movable components that can dynamically transition between idle and working positions. The device moves along the wire path and adjusts its configuration based on whether wire processing is needed, enabling automated adaptation to different operational states
2Volume of stationary object
If leftover wire is stored in bulk, then storage space is occupied, but wire disposal frequency is reduced
Solution Approach 1:
The bending device coils leftover wire into compact spiral or helical shapes using rotating rollers. This curvature-based coiling method reduces the volume occupied by leftover wire from linear extension to compact cylindrical form, minimizing storage space requirements while maintaining organized wire disposal
Solution Approach 2:
The bending device creates nested spiral coils where wire is wound around itself in concentric layers. This nesting arrangement maximizes wire density in minimal space, allowing compact storage of disposed wire without requiring large storage volumes
3Ease of operation
If bending device is always in working position, then wire bending is ready, but wire feeding is hindered
Solution Approach 1:
The bending device transitions dynamically between idle and working positions based on operational needs. During normal wire feeding, the device remains retracted or in idle position clear of the wire path. When leftover wire detection occurs, the device moves to working position to perform bending operations
Solution Approach 2:
The bending device is segmented into movable functional components that can be positioned independently. The device separates its bending function from the main wire feeding path by using movable arms or rollers that engage only when needed, allowing clear wire feeding during normal operation and targeted bending when required
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Automates the disposal of leftover wire, saving labor time and storage space by winding it into a small volume, allowing for periodic easy emptying of a collection container, thus simplifying the process.
Implementation Method 1
At least one of the three rolls 5, 6, 7 can be driven so that the entire leftover wire 3 runs through the bending device 4 and is coiled without a further drive

AI summary
In order to simplify leftover wire (3) at the tying machines used in pulp production, a device is used that has an inlet guide (2) for the leftover wire (3) and a bending device (4) to bend the leftover wire running through continuously into a helical or spiral shape.
