Winding Machine Axial Displacement for Coil Collision Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Winding machines face challenges in ensuring a sufficient time frame for removing finished coils without risking collisions between coils of increasing diameter, due to the dependency on spindle distance and infeed speed, which complicates the changing and removal process.
Innovation Solution
A displacement device is used to move completely wound coils into a removal position without axial overlap, allowing for extended removal time and preventing collisions by guiding the coils past each other axially, while also enabling easier access for manual or automatic removal.

1Area of stationary object
If the distance between spindles is kept small to reduce machine size, then the overall size of the winding machine is reduced, but the time available for removing finished coils is insufficient and collision risk increases
Solution Approach 1:
The invention introduces a displacement device that moves finished coils axially (in the longitudinal direction) to create an offset between coils on adjacent spindles. This axial displacement adds a dimensional solution to the spatial conflict, allowing coils to be positioned at different axial locations rather than requiring increased radial distance between spindles. The displacement device creates a staggered arrangement where finished coils are shifted axially relative to active coils, preventing collision while maintaining compact spindle spacing.
2Loss of time
If the distance between spindles is increased to allow longer removal time, then collision risk is reduced, but the overall size of the winding machine increases
Solution Approach 1:
The invention employs a dynamic displacement device that actively adjusts the axial position of finished coils during the winding process. Rather than relying on fixed spindle spacing, the system dynamically repositions coils to optimize both safety and compactness. The displacement device can be actuated at appropriate moments to shift coils axially, creating time-dependent spatial arrangements that adapt to the winding cycle phase and removal timing.
3Productivity
If infeed speed is increased to improve productivity, then output increases, but the time frame for coil removal becomes even more constrained
Solution Approach 1:
The displacement device performs preliminary action by positioning finished coils axially before removal is needed. By pre-displacing coils to offset positions, the system prepares the spatial arrangement in advance, creating a safety buffer that accommodates faster infeed speeds. This preliminary positioning ensures that even at high productivity rates, the axial offset is already established, preventing collision regardless of how quickly new coils are formed.

AI summary
The invention relates to a winding machine (1), on which, in alternation, a spool (8) is wound in a winding position (13) of a spindle (5), while at the same time a completely wound spool (6) is removed from a spindle (4). With winding machines (1) according to the prior art having a small spacing (36) of the rotational axes (18, 19) of the spools (6, 8), the completely wound spool (6) must be removed quickly before the spool (8) has reached a critical diameter which would cause a collision of the lateral faces of the spools (6, 8). According to the invention, the completely wound spool (6) is moved by means of a displacement device (23) over a displacement path (25) before or during the winding process of the spool (8), such that the axial extensions (14, 15) of the spools (6, 8) have no overlap, but rather have a spacing (26). The collision of the spools (6, 8) can thus be prevented as the diameter of the spool (8) increases, whereby a more compact design with a smaller spacing of the spindles (4, 5) is made possible and an operator has more time to remove the completely wound spool (6).
