Description

An automatic splicing device and method for fabric ring spinning machines

Technical field

The present invention relates generally to fabric spinning machines and in particular to an automatic yarn splicing device for fabric ring spinning machines. More particularly, the present invention relates to an improved yarn break lifting device in an automatic splicing device for fabric ring spinning machines.

Background technique

In textile mills, ring spinning machines are key machines for producing continuous yarn. Typically, the textile roving material produced by the roving frame is fed into the ring spinning machine. The roving material is first drawn and twisted and then wrapped around a package called a bobbin or yarn tube. During this spinning process, yarn breakage in the above mentioned ring spinning machines is a common and frequent problem that requires continuous manual attention. Today, yarn breakage is still a major disadvantage of ring spinning machines. Traditionally, large numbers of workers are used to continuously monitor ring spinning machines, and such spinning machines often include more than 1,600 spindles throughout the entire machine frame, which is often over 75 meters in length. In addition to regular monitoring, broken yarns must be spliced together and the corresponding yarn spinning sequence restarted to avoid wasting yarn. Since the ring spinning machine is installed very compactly in the spinning mill, it is very tedious for the operator to monitor the ring spinning machine in the gangway throughout the day.

To overcome the above problems, automatic splicing devices are being developed. The automatic splicing device takes the form of a movable trolley with wheels/tracks/rails. The above-mentioned splicing device contains a built-in driving unit, sensing unit and supporting unit. The automatic splicing assembly includes multiple modules for picking up broken yarn on the bobbin, inserting yarn into the yarn guide, absorbing yarn, and splicing yarn in the drafting area. The yarn picking module includes an air blowing device fixedly installed on the automatic splicing device.

This method and device for pneumatic separation and suction of broken yarn ends has been disclosed in US Pat. No. 4,132,057. According to the patent, the main shaft rotates intermittently, and at the same time, three blowing nozzles with single holes are used to blow air to the broken yarn to effectively separate the broken wire ends. However, the above method cannot reliably lift the broken yarn from the bobbin in practice.

In another known solution, described in German patent DE 3012210, in addition to the axial blow nozzle, complex brushes or tangential blow nozzles are used to separate the broken yarn from the bobbin. However, the above solution cannot successfully lift the broken yarn end from the bobbin. In addition, the above solutions contain complex structural layouts that require separate installation and execution arrangements.

All known yarn lifting solutions are unable to lift fine yarns (e.g. yarns with Ne>60) or separate them from the bobbin. These failed attempts tend to further increase the number of attempts using high-intensity compressed air, resulting in longer cycles than previous cycles. The above number of attempts also leads to an increase in compressed air consumption, which in turn leads to an increase in operating costs. In addition, long-term air blowing on the surface of the wire tube will also lead to a decrease in yarn quality, such as an increase in yarn hairiness, twist defects and the generation of neps. If high-pressure blowing is used to blow fine yarn from the bobbin, the yarn already wound on the bobbin will also loosen. Among all known yarn break lifting devices, the splicing efficiency of the automatic splicing device is very low. Therefore, the low efficiency of automatic splicing devices affects the overall production efficiency of ring spinning machines in spinning mills.

There is a need for an improved yarn lifting device for separating yarn of all counts from the bobbin.

The invention provides an improved yarn lifting device for the automatic splicing device of the ring spinning machine to successfully separate the broken yarn ends from the bobbin, and its structural arrangement is simple and reliable.
