Active Strap Dispenser with Rotating Coil Carriage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strap dispensers require manual operation by the operator to pull the strap from the coil, leading to inefficiencies such as excess strap waste, insufficient strap length, and potential dispenser tipping.
Innovation Solution
A strap dispenser that actively dispenses strap from a supported coil using a rotatable strap-coil carriage and a strap-dispensing assembly driven by an actuator, controlled by a controller and powered by a battery, ensuring precise and controlled dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual strap pulling is used, then device complexity is reduced, but manufacturing precision and productivity deteriorate due to operator guessing and inconsistency
Solution Approach 1:
The strap dispenser performs the dispensing operation automatically without requiring manual intervention. The actuator-driven carriage system self-regulates strap release, eliminating the need for operator guessing while maintaining relatively simple device construction.
Solution Approach 2:
The patent replaces manual mechanical pulling with an actuator-driven mechanical system. The actuator controls the carriage movement and strap dispensing through mechanical means, achieving precise control without complex electronics or automation systems.
2Ease of manufacture
If manual strap pulling is used, then device complexity is reduced, but productivity deteriorates due to excess strap waste and insufficient length
Solution Approach 1:
The automatic dispensing system eliminates operator intervention, preventing both excess strap waste and insufficient length issues. The system self-regulates to provide the correct strap amount, improving productivity without adding complex control systems.
Solution Approach 2:
The system incorporates feedback mechanisms where the actuator and carriage work together to monitor and control strap dispensing in real-time, ensuring the correct length is provided for each strapping operation and preventing waste or shortages.
3Ease of operation
If manual strap pulling is used, then ease of operation is maintained, but stability deteriorates due to dispenser tipping
Solution Approach 1:
The patent replaces manual pulling operations with an actuator-driven mechanical system. This substitution eliminates the destabilizing effect of manual force application while maintaining ease of operation through simple actuator control, preventing dispenser tipping.
4Manufacturing precision
If active dispensing with actuator is used, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent uses actuator-driven mechanical components to achieve precise strap dispensing. The mechanical carriage and actuator system provides controlled, repeatable dispensing precision without requiring complex electronic controls or sophisticated automation systems.

AI summary
Various embodiments of the present disclosure provide a strap dispenser configured to support a strap coil and to actively dispense strap from the strap coil; the strap dispenser comprises a frame (100), a strap-coil carriage (200) rotatably mounted to the frame and configured to support the strap coil, a dispenser actuator (350) operable to dispense strap from the strap coil and cause the strap-coil carriage to rotate relative to the frame, and a communication interface (400) operable to establish communication with an external strapping tool and, thereafter, to receive an instruction from the external strapping tool for controlling operation of the dispenser actuator.
