DE20008405U1 - System for laying materials such as threads, ropes or wires on a bobbin - Google Patents

Description

A laser distance sensor 4 is mounted with its laser beam in such a way that it forms an aligned line with the wire 2 to be wound up.

A sudden large change in the distance of the laser beam through a coil flange is evaluated in the control system as flange detection, i.e. reversing the laying direction.

Smaller distance changes detected by the laser distance sensor 4, peaks 6 and valleys 7 do not lead to a change in the laying direction.

According to a setting in the control system, a mountain 6 is skipped with the laying system 5 and a valley 7 is filled.

When skipping and filling peaks 6 and valleys 7, the laying speed is accelerated or slowed down accordingly using the laying system 5.

Benefits achieved:

The invention ensures that the laying system independently achieves an optimal winding pattern regardless of the external spool dimensions and without control or intervention by the operating personnel.

Further embodiment of the invention:

An advantageous embodiment of the invention is specified in claim 2.

The further development according to claim 2 for the application of the laying system makes it possible to repair coils that have already started badly due to a possible external fault or a different laying system.

Description:

An embodiment of the invention is explained with reference to Figures 1 to 4.

Show it:

Fig. 1 the spool optimally wound

Fig.2 the spool is badly wound, laying width is set too far outwards from the spool flanges.

Fig.3 the spool is badly wound, laying width is set too far inwards from the spool flanges.

Fig.4 the coil, which is to be repaired independently by a laying system.

As can be seen from Fig.4, the wire guide roller 3, which is attached to the laying system 5, must be moved between the two spool flanges 1.

The laying speed is related to the spool speed.

When the wire guide roller 3 of one of the spool flanges 1 is reached, the laying direction must be changed.

Laser laying

State of the art:

Materials such as threads, ropes and wires are usually wound onto spools made of wood, plastic or metal for further processing.

Due to a rotating coil body (called a coil for short), the material, in this case wire, must also be laid continuously across the entire width of the coil.

This is usually done with a separate drive in which the wire is guided mechanically and depending on the spool speed from left to right, i.e. from the left to the right spool edge (spool flange), etc.

An adjustment for switching the laying drive from the spool flange to the spool flange is made by the operating personnel according to visual inspection and personal experience by means of limit switches or other given means.

These necessary settings of the corresponding spools are very time-consuming for the operating personnel and require constant monitoring in order to achieve a satisfactory spooling result.

Dimensional tolerances in new or deformed used coils therefore require a corresponding adjustment in the laying width.

Problem:

The invention specified in claim 1 is based on the problem of creating a laying system which achieves an optimal winding pattern without adjustment, regardless of the external dimensions of a coil.

Solution:

This problem is solved with the features listed in claim 1 (if necessary, citation of the features verbatim). . .

Claims (2)

1. The system for laying materials such as threads, ropes or wires on a spool body is characterized in that a laser distance sensor measures the distance to the winding material (wound on a spool body), enters the value into a control system (PLC), which compares the value with stored data, calculates changes, evaluates them and thus sends control signals to a laying drive, which thereby changes its speed (laying pitch) so that the thread, rope or wire guided by the laying unit is wound further in such a way that a relatively uniform surface (without hills or valleys) is created, as far as the winding material allows. 2. The system according to claim 1 is characterized in that the laser distance sensor also detects the flange of the coil body, this large change in distance is evaluated in the control system as a turning signal for the laying drive, and thus reverses automatically.
