Abstract

A ring spinning machine with a drafting device, with pneumatically weighted top rollers on its top roller supports and weighting bars, on each top roller support and weighting bars, a high-pressure pipe branching from a central high-pressure pipe Weighting elements leading to top rollers. Leakage indicators (10) are provided on all high-pressure lines of the roller bearings and weighting bars, which allow visual monitoring of the occurrence of leaks in the relevant high-pressure lines.

Description

ring spinning machine

The invention relates to a ring spinning machine with a drafting device. Pneumatically weighted top rollers are arranged on the top roller supports and weight bars. On the top roller supports and weight bars, high-pressure The pipes lead to the weighting elements of the top rollers.

Ring spinning machines with pneumatically weighted top rollers are common today. Leakage of the pneumatic system of the spinning machine due to aging processes or mechanical damage, the main areas of danger for leakage are in the high-pressure channels guided on the top roller bearings and weighting bars. Particularly at risk are the points of connection of the high-pressure channels to the central high-pressure channel of the spinning machine, and the points of connection of the high-pressure channels to the weighting element, as well as the weighting element itself. Although the utility model G8521340 discloses a leakage monitoring device for spinning machines, this monitoring device is located in the central high-pressure passage, so the occurrence of leakage can be reliably determined, but the exact location of the leakage cannot be determined. Modern spinning machines have 300 to 500 top roller supports and weight bars, so finding leaks is time consuming.

In order to solve the above-mentioned problems, the invention proposes a ring spinning machine of the stated type, the spinning machine according to the invention is characterized in that leak indicators are provided on all high-pressure lines of the top roller support and the weighting bar, They allow visual monitoring of the occurrence of leaks in the associated high pressure piping. This leak indicator can also complement the leak indicators for central high-pressure lines. Leaks at any point in the pneumatic system of the ring spinning machine can thus be quickly detected. The leakage indicators can each have a floating body, which appears in the region of the viewing window when a leak occurs, or instead of a floating body, an impeller or any other sensor can be used to monitor the pressure medium flow. Pressurized medium flow occurs only in the event of a leak, while normal pressure is present in all systems within the normal operating range. In addition to the visual indication of a leak, the leak indicator can also trigger an acoustic signal. The presence of a leak can thus be determined more quickly.

Two embodiments of a leak indicator for a ring spinning machine will be further explained below with reference to the accompanying drawings.

in:

Figure 1 is a side view, partly cut away, of a leak indicator with a floating body;

Figure 2 is a side view, partly cut away, of the impeller leak indicator.

Fig. 1 shows a high-pressure line 10, the two ends of which are connected to the valves arranged on the top roller support and the weighting rod. Inside the high-pressure pipeline 10, a movable ball 11 is provided along the longitudinal direction of the pipeline 10, and when the pressure medium flows in the high-pressure pipeline 10 along the arrow direction 12, it is pressed into the scope of the window 13. The appearance of the ball 11 in the range of the viewing window is a reliable indication that there is a leak in the high pressure channel 10 .

In the valve 20 of FIG. 2 , an impeller 21 is arranged in the flow path 22 , 23 of the pressure medium. As soon as the pressure medium flows due to the occurrence of a leak, the impeller 21 rotates, which can again be observed through the viewing window.

The embodiments of leak indicators shown in Figures 1 and 2 are merely exemplary. Other types of sensors such as vanes may also be provided to determine the flow of pressure medium.
