Locking mechanism of fabric coiler

Abstract

A device (200) is set up to be combined into a fabric coiler, so that the winding shaft (20) is transferred from a waiting position (3) to a winding position (4) and / or a rolling position (5) by the device. The device has a lever arrangement structure that encloses the winding shaft from one side in a locked state, so that the lever arrangement structure observes in the longitudinal direction of the winding shaft and is opened towards one side of the winding shaft, and the lever is arranged in such a way, so that the gravity of the winding shaft is prevented from being guided into the lever arrangement structure in a manner of being used for canceling the locking force. The fabric coiler (1) is provided with a fiber net for winding the first winding shaft, and guiding a second winding shaft to a waiting position, and is provided with the device. The device is arranged on the conveying section in a waiting state, so that the lever arrangement structure clamps the second winding shaft ina clamping manner. The conveying section is configured in that the clamped second winding shaft moves from the waiting position towards the starting and winding position and / or the coiling position.

Description

technical field [0001] The present invention relates to a locking mechanism for a web winding machine for securely clamping a winding shaft and to a web winding machine equipped with such a locking mechanism. Background technique [0002] Fiber web winders are known per se. They are used for winding fiber webs, for example from cards, on winding shafts. For this purpose, the empty winding shafts are wound one after the other in an automatic exchange. This is accomplished by directing the incoming web material around rotating contact rolls. An empty winding shaft provided with an adhesive surface and rotating in the opposite direction to the touch roll rests against the touch roll and receives the fiber web from the touch roll due to adhesion. Empty winding shafts are generally accommodated in the depository of the fiber web winding machine. In order to wind the empty winding shaft, it is transferred from the storage place into a waiting position, in which the winding sha...

AI Technical Summary

Problems solved by technology

[0003] For locking the winding shaft with the jaws, jaw arrangements are known which act on both sides with respect to the axis of rotation of the winding shaft, which are very complex in construction

In addition, the locking elements of such jaw arrangements have to approach the winding shaft from both sides, which complicates the combination of the movement path of the locking mechanism and the especially drive technology of the locking mechanism in the web winding machine.

In addition, with regard to energy losses, when the drive element actuates the jaws, it can result that the winding shaft, due to its weight, comes out of the locking mechanism and moves uncontrollably, for example falls.

This is a high risk of injury to persons located nearby and a risk of damage to other components such as the web winding machine
