Winding Chamber Bundle Transfer via Pivoting Lever
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices face challenges in efficiently transporting wound bundles from the winding chamber to downstream transport devices due to the need for bundle standstill and simultaneous unwinding during transport, which complicates the transition from winding to unwinding positions.
Innovation Solution
A pivoting lever mechanism is introduced, with a pressure roller mounted on its free end, which can be pivoted to push the bundle out of the winding chamber onto a downstream roller table section with an adjustable transport plane, allowing for smooth transfer by aligning the roller table's plane at an angle to the winding chamber's support plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the bundle is transported from the winding chamber to the downstream transport device based on standstill in the winding chamber, then the bundle can be stationary during transport, but the bundle begins unwinding rotation simultaneously which complicates the transition
Solution Approach 1:
The roller table's inclination angle is made dynamically adjustable during the transport process. The roller plane is inclined at an angle alpha to the support plane of the winding chamber, and this angle can be changed during operation to first receive the bundle in a stable position, then adjust to facilitate unwinding and transfer to the downstream device, resolving the contradiction between stability and transition complexity
Solution Approach 2:
The roller table is pre-positioned at a specific inclination angle to receive the bundle in a stable manner before the unwinding process begins. This preliminary positioning ensures bundle stability during initial transport, and subsequent angle adjustments are made only when needed for the transition phase
2Ease of operation
If the roller plane of the downstream transport device is aligned parallel to the winding chamber support plane, then the transport path is straightforward, but the bundle cannot be properly transferred without causing mechanical stress
Solution Approach 1:
The roller table inclination angle is dynamically adjusted during the transfer process. Initially, the roller plane is inclined at an angle alpha to the winding chamber support plane to facilitate proper bundle reception and transfer. During the actual transfer operation, the angle is adjusted to optimize the transfer path, reducing mechanical stress on the bundle while maintaining ease of operation

AI summary
The invention relates to an apparatus for winding and unwinding rolled strip (WB) discharging from a mill train (WS), in which apparatus the rolled strip (WB) discharging from the mill train (WS) is introduced by a set of bending rolls (BR) into a winding chamber (WK) having a rotationally driven roller pair (RP) and is wound into a coil (WB), and the coil is then put onto a roller table (GR) and unwound from these rollers with the direction of rotation being reversed and the start of the strip is fed to a driver device (RT). The apparatus is improved by a supporting slide (TS) which can be pushed into the winding chamber (WK) and in whose side walls a pivoted lever (SH) is mounted, the free end of which carries a pressure roller (AR) which can be put onto the rolled strip coil and pushes the latter out of the winding chamber (WK) onto the adjoining roller table (GR).
