Description

Automatic splicing device for textile ring spinning machines

technical field

The present invention relates to a textile ring spinning machine. In particular, the present invention relates to an automatic yarn piecing device for spinning the ends of broken yarns in textilering spinning machines. Furthermore, embodiments of the present invention relate to improved mounting assemblies in automatic engagement devices for textile ring spinning machines.

Background technique

In the textile industry, ring spinning machines are commonly used to spin fibers such as cotton, linen or wool to produce yarn. The fibrous material can be supplied to the ring spinning machine in the form of rovings. Further, the ring spinning machine draws the roving to the desired fineness and imparts sufficient twist to eventually form a continuous yarn, which is then wound onto a bobbin for storage. During spinning operations, yarn breakage in ring spinning machines is an unavoidable situation. Therefore, in order for the ring spinning machine to operate efficiently and continuously, it is necessary to engage the yarn breaks. This process is called yarn joining. Yarn joining is the process of joining/splicing broken yarns. Thus, the process helps to quickly restart the yarn spinning sequence. The yarn joining process is very critical in the yarn spinning operation, which determines the productivity.

In the conventional method, the joining of the broken yarns can be done manually, while the operator of the spinning machine walks around the spinning zone and finds the broken yarns to join the broken yarns together. In manual splicing operations, the operator may have to perform periodic inspections over the entire length of the frame, which is typically about 75 meters long and can include about 1600 spindles. In addition to regular monitoring, broken yarns must be engaged and the corresponding yarn spinning sequence must be restarted in time to avoid wasting yarn. Since several ring spinning machines of this type are installed in close proximity to each other in a spinning mill, it becomes cumbersome for operators to access multiple channels to monitor the ring spinning machines.

With the advent of modern technology, automatic splicing devices have been used in spinning mills to overcome some of the limitations associated with manual splicing operations. Typically, the automatic engagement device is mounted on rails/floors/wheels provided near the frame of the ring spinning machine. The automatic engagement device may employ an automatic engagement device similar to a robotic arm, or may be configured to accommodate an operator for engagement. The automatic splicing device can move back and forth on rails/wheels over the entire frame length of the ring spinning machine and perform splicing operations. The splicing device can be mounted on a platform that moves back and forth on the shop floor to drive the splicing device to perform splicing operations over the entire length of the ring spinning frame.

Typically, an automatic splicing device includes a number of modules for picking up the yarn from the cop, inserting the yarn into the traveller, sucking the yarn and splicing the yarn in the drafting zone, etc. In an automatic yarn joining device, the orientation/alignment of multiple modules (eg, yarn pickup module, yarn insertion module, yarn suction module, and yarn joining module) relative to each other can be very critical and important. The above-mentioned modules in conventional automatic splicing devices are often oriented along different surfaces, which can lead to improper module alignment. Therefore, the movements of the modules described above are asynchronous with respect to each other and take place along different planes. Improper module alignment can affect splicing operations and result in inefficient yarn splicing.
