Description

Automatic joining device for textile ring spinning machine
Technical Field
The invention relates to a spinning ring spinning machine. In particular, the present invention relates to an automatic yarn joining (piecing) device for spinning the ends of broken yarns in a ring spinning machine (textile ring spinning machine). Furthermore, embodiments of the present invention relate to an improved mounting assembly in an automatic joining device of a textile ring spinning machine.
Background
In the textile industry, ring spinning machines are commonly used to spin fibers (e.g., cotton, linen, or wool) to produce yarns. The fiber material may be provided to the ring spinning machine in the form of roving. Further, a ring spinning machine stretches the roving to a desired fineness and imparts sufficient twist, finally forming a continuous yarn, which is then wound onto a bobbin for storage. During the spinning operation, breakage of the yarn in the ring spinning machine is an inevitable situation. Therefore, in order to efficiently and continuously operate the ring spinning machine, it is necessary to engage the broken yarn. This process is called yarn splicing. Yarn splicing is the process of connecting/splicing broken yarns. This process therefore helps to quickly restart the yarn spinning sequence. The yarn joining process is very critical in yarn spinning operations, which determines productivity.
In the conventional method, the joining of the broken yarn can be performed manually, while the operator of the spinning machine walks around the spinning zone and finds the broken yarn to join the broken yarn together. In a manual engagement operation, the operator may have to perform periodic inspections throughout the length of the gantry, which is typically about 75 meters long and may include about 1600 spindles. In addition to the regular monitoring, the yarn breakage has to be engaged and the corresponding yarn spinning sequence has to be restarted in time to avoid wasting yarn. Since several ring spinning machines of this type are installed close to each other in one spinning mill, it becomes cumbersome for an operator to access multiple passages 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 engaging means are mounted on rails/floors/wheels arranged near the frame of the ring spinning machine. The automated bonding apparatus may employ automated bonding equipment similar to a robotic arm, or may be configured to accommodate an operator for bonding. The automatic joining device can be moved back and forth on the rails/wheels over the entire frame length of the ring spinning machine and perform the joining operation. The splicing device may be mounted on a platform that is moved back and forth across the shop floor to carry the splicing device through the length of the ring spinning machine.
Generally, an automatic joining device comprises a plurality of modules for picking up a yarn from a cop (cop), inserting the yarn into a traveler, sucking the yarn and joining the yarn in a drafting zone, etc. In automatic yarn joining devices, it can be very critical and important that a plurality of modules (e.g., a yarn pick-up module, a yarn insertion module, a yarn suction module, and a yarn joining module) are oriented/aligned with respect to each other. The above-described modules in conventional automated bonding apparatuses are typically oriented along different surfaces, which may result in improper module alignment. Thus, the movement of the modules relative to each other is not synchronized and takes place along different planes. Improper module alignment can affect the splicing operation and result in inefficient yarn splicing.

Typically, an automated bonding apparatus comprising a plurality of modules is mounted on a platform that moves back and forth across the floor of the plant. The multiple modules in conventional automated bonding apparatuses are often oriented along different surfaces or planes or shelves, which can result in improper module alignment. Thus, the movement of the modules relative to each other is not synchronized and takes place along different planes. Improper module alignment can affect the splicing operation and result in inefficient yarn splicing.
To overcome the above disadvantages, the present invention provides an improved mounting assembly for an automatic splicing device of a textile ring spinning machine.
Accordingly, embodiments of the present invention provide an automatic joining apparatus. The apparatus includes a carriage defining a rail. Furthermore, a first housing, a second housing and a third housing are provided, wherein the first housing comprises a lifting module and an insertion module. The second and third housings are provided with a suction module and an engagement module, respectively. The first and second housings are slidably mounted on the guide rails, and the third housing is fixedly mounted on the bracket. Further, the plurality of housings comprising the plurality of modules are aligned along a common axis of the carriage such that all of the modules can be operated simultaneously to engage the yarn. This improves the accuracy of the joining and reduces the time required for the joining.
The following paragraphs describe the present invention with reference to fig. 1.
Fig. 1 shows a schematic view of an automatic joining device 1 for a textile ring spinning machine 11. The apparatus 1 as shown in fig. 1 may comprise a plurality of modules for performing the joining operation. In one embodiment, the plurality of modules may include, but is not limited to, a yarn lifting module 2, a yarn insertion module 3, a yarn suction module 4, and a yarn joining module 5. In the above and in the following, "yarn lifting module" and "lifting module", "yarn insertion module" and "insertion module", "yarn suction module" and "suction module", "yarn joining module" and "joining module" are used interchangeably. The yarn joining device 1 is provided along a line/row of a ring spinning machine 11, and in the ring spinning machine 11, a supplied fiber bundle (fiber placement) is spun into a yarn by means of linear drawing using a drawing unit 13. Thus, the produced yarn is subsequently wound on the annular pirn 12, before further processing. The yarn lifting module 2, the yarn inserting module 3, the yarn suction module 4 and the yarn joining module 5 are mounted on a common frame 10 of the automatic joining device 1. A plurality of modules 2, 3, 4 and 5 mounted on a vertical support 10 are arranged along a common vertical axis (a-a). In one embodiment, the support 10 extends along a vertical axis (A-A) perpendicular to the support body of the automated joining device 1.
The yarn lifting module 2 can be provided with an air blowing device for lifting the yarn coming from the annular pirn 12. Furthermore, the yarn insertion module 3 can be provided with a clamp for inserting the yarn into the annular bead ring of the ring. The yarn lifting module 2 and the yarn insertion module 3 are mounted on a first housing or carriage 6, the first housing or carriage 6 being slidably mounted on a guide rail 9 of the automatic joining device 1. Further, the guide rail 9 is fixed to a bracket 10 of the automatic joining apparatus 1.
The thread suction module 4 is mounted on the second housing 7, and the second housing 7 slides along the guide rail 9 of the automatic joining device 1. The second housing 7 slides over the first housing 6 and the second housing 7 can also be fixed to a common rail 9 of a common bracket 10. The yarn suction module 4 comprises a top suction hood unit (not shown) to suck and hold the picked yarn end from the pirn 12 for subsequent engagement.
Furthermore, the yarn joining module 5 is provided with a joining arm assembly. The engaging arm assembly can be used to direct the yarn held by the yarn suction module 4 towards the drafting unit 13. The yarn joining module 5 is mounted in the third housing 8. The third housing 8 may be rigidly fixed to the bracket 10 of the automatic joining unit 1 at the top of the bracket 10. The engaging arms provided in the yarn engaging module 5 are movable towards the drafting unit 13 to engage the yarn held in the suction module 4.
Thus, the entire set of yarn lifting module 2 and yarn insertion module 3 arranged in the first housing 6 and the yarn suction module 4 arranged in the second housing 7 are movable along the guide rail 9. Thus, the entire device with the plurality of modules 2, 3, 4, 5 and the guide 9 is placed in a common rack 10 along a common vertical axis (a-a) of the automatic joining device 1. The yarn lifting module 2, the yarn inserting module 3 and the yarn suction module 4 are mounted on their respective first and second housings 6, 7 in such a way that they can be moved back and forth relative to the ring spinning machine 11. Such movement of the first and second housings 6, 7 may be achieved by suitable devices or actuators (e.g. pneumatic/hydraulic/electric/linear cylinders) (not shown). Similarly, during the yarn joining operation, suitable pneumatic/hydraulic/electric/linear actuators/cylinders may be used to drive the joining arms of the yarn joining module 5, configured in such a way that they can be rotated towards or away from the drafting system 13 of the ring spinning machine 11. The axis about which the yarn joining module 5 can rotate towards the drafting system 13 can be perpendicular to the axis about which the plurality of modules 2, 3, 4 and 5 are oriented.
In one embodiment of the invention, the plurality of modules 2, 3, 4 and 5 may be oriented along a horizontal axis. In another embodiment of the invention, the plurality of modules 2, 3, 4 and 5 may be oriented at any suitable angle such that all of the modules 2, 3, 4 and 5 are located on a common axis.
In one embodiment of the invention, the first housing 6 and the second housing 7 may be moved together to provide a break to the yarn joining module 5.
In one embodiment of the invention, the controller may activate the actuator to provide sliding movement of the first housing 6 and the second housing 7. In one embodiment of the invention, the controller may also initiate a rotational action of the third housing 8.
Since the first housing 6 and the second housing 7 are mounted on the same guide rail 9 of the common carrier 10, the blowing device of the yarn lifting module 2, the clamping member of the yarn insertion module 3 and the suction portion of the yarn suction module 4 can be operated in an aligned manner during the joining operation. Thus, better joining results are obtained due to the synchronous alignment between the plurality of modules 6, 7 and 8. The splicing arms of the yarn splicing module 5 are also mounted in line with all other modules on top in a common carrier 10 of the automatic splicing unit 1.
In one embodiment of the present invention, the present invention provides an improved mounting assembly for a plurality of modules (e.g., a yarn take-up module, a yarn insertion module, a yarn suction module, and a yarn splicing module) of an automatic yarn splicing device of a textile ring spinning machine.
In one embodiment of the invention, the invention provides proper alignment and synchronized movement of the yarn take-up module, the yarn insertion module, the yarn suction module and the yarn joining module of the automatic yarn joining device during operation.

Those skilled in the art will also appreciate that, in fact, any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description or the figures, is to be understood as intended to include the possibility of one, any or all of the plurality of terms. For example, the phrase "a or B" should be understood to include the possibility of "a" or "B" or "a and B".
Although various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration, and are not intended to be limiting, within the true scope and spirit of the disclosure shown in the specification.
