Carding Wire Mounting Device with Force Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing winding devices for profile wire onto rollers lack precise measurement of the force acting on the wire, particularly during the tensioning process, as they only account for braking forces and ignore external influences and deflection points.
Innovation Solution
A mounting device with a movably mounted pull-up arm equipped with a force measuring device that records the force component parallel to the profile wire, allowing for precise measurement of the total force acting on the wire, including braking, straightening, and tilting devices, using sensors to detect forces between the pull-up arm and the guide device or between the guide rail and the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a braking device is used to control the longitudinal pull on the profile wire, then the braking force can be fixed and determined, but the wire tension in the windings is not precisely recorded because other forces acting on the wire are not taken into account
Solution Approach 1:
A force measuring device is introduced as an intermediary element between the pull-up arm and the frame. This device measures the total force acting on the pull-up arm, which includes braking forces, deflection point forces, and other external influences. The force measuring device serves as a mediator that captures the complete force profile without requiring complex separate measurement systems for each force component.
Solution Approach 2:
The invention merges multiple force components (braking force, deflection point forces, and other external forces) into a single measurement by measuring the total force on the pull-up arm. Instead of separately measuring each force component with multiple devices, the system combines them into one comprehensive measurement that represents the total wire tension.
2Manufacturing precision
If a pressure foot is arranged on the mounting arm to press the windings together, then the windings can be pressed without gaps, but the force acting on the wire at deflection points and on the pressure foot is not recorded
Solution Approach 1:
The force measuring device acts as an intermediary that captures the forces from multiple sources including the pressure foot. By measuring the total force on the pull-up arm, the system indirectly measures the forces from the pressure foot and deflection points, eliminating the need for separate force sensors at each location while maintaining comprehensive measurement coverage.
Solution Approach 2:
The force measuring device serves multiple functions: it measures braking forces, deflection point forces, pressure foot forces, and other external influences all through a single measurement system. This universal approach allows the same device to capture forces from various sources without requiring separate specialized measurement systems for each function.
3Ease of operation
If the pull-up arm is movably mounted on the frame via a guide device, then the profile wire can be guided onto the roller in a controlled manner, but the force acting on the pull-up arm is not directly measured
Solution Approach 1:
The invention merges the guiding function with the measurement function by measuring the total force on the pull-up arm. The movable mounting allows controlled wire guiding while the force measuring device simultaneously captures all forces acting on the arm, including guiding forces, braking forces, and external influences, combining multiple functions into a unified system.

AI summary
The device (1) has a frame (5) on which a mounting arm (4) is supported. A force measuring arrangement measures force acting on the mounting arm during a fitting operation. The mounting arm supports a brake arrangement that is arranged to decelerate an all-steel card clothing (2) moving through the device. The mounting arm supports an alignment arrangement that straightens the all-steel card clothing passing through the device. The force measuring arrangement is arranged between a guide arrangement (11) and the mounting arm. USE : Mounting device for mounting all-steel card clothing on a drum used in a carding machine of a textile industry. ADVANTAGE : The mounting arm is movably connected with the guide arrangement in a longitudinal direction of a profile wire, so that the force measuring arrangement is effective in the longitudinal direction of the profile wire and detects minimal longitudinal displacements of the mounting arm relative to the guide arrangement. The mounting arm can be moved parallel to a drum so as to enable pivoting of the mounting arm about a longitudinal axis of a guide rail, so that the mounting arm can be freely aligned corresponding to a moving direction of the profile wire.
