Technical Field
The invention relates to a false twist texturing machine with a correlation system capable of correlating spinning finished product data and false twist texturing finished product data, and a method for correlating spinning finished product data and false twist texturing finished product data on the false twist texturing machine.
Background
Melt spinning and winding devices extrude the melt and cool it into filaments, which are drawn and wound into spun products, so-called "pre-oriented yarns". The false twist texturing device heats, cools and false twists the spun product, and then winds the spun product to form a false twist textured product, namely a so-called drawn textured yarn.
During the whole process from melt spinning winding to false twist texturing, there are many factors affecting the quality of the final yarn, including the factors affecting the processing devices in the false twist texturing equipment and the factors affecting the processing devices in the melt spinning winding equipment.
The known prior art, for example WO2016120187, describes a method and apparatus that can associate a false twist texturing apparatus with a melt spinning and winding apparatus such that the final data set of the false twist textured finish shows the entire manufacturing history.
In the process of realizing the method and the system, the corresponding relation between the spinning finished product and the false twist texturing finished product in the actual production needs to be considered.
Disclosure of Invention
Based on the above-mentioned technical problems in the prior art, the present invention discloses a false twist texturing machine and a method for associating spinning product data with false twist texturing product data, so as to form a device and a method for associating spinning product data with false twist texturing product data in a renewable manner. The technical scheme of its utilization is as follows:
the first technical proposal is that the false twist texturing machine comprises a machine controller for controlling the false twist texturing machine, a yarn rack for placing a plurality of spinning finished products, and an association system for associating the spinning finished product data with the false twist texturing finished product data; wherein the association system comprises: the identification equipment is electrically connected with the machine controller and is used for inputting the position information of the spinning finished product; the detection device is electrically connected with the machine controller and is used for detecting a connection knot between the adjacent spinning finished products; the matching module is arranged in the machine controller and is used for matching the position information of the false-twist deformation finished product with the position information of the spinning finished product; wherein the detection device is in communication with the matching module.
As the beginning of the whole false twist texturing process, the spinning finish is located on a creel, which becomes a false twist textured finish after being processed in a false twist texturing machine. In order to ensure the production continuity, a plurality of spinning finished products are adjacent and connected end to form uninterrupted yarn supply. After the position information of the spinning finished product is recorded and matched by the matching module, a false twist deformation finished product is corresponding to a spinning finished product. The matching module updates the matching information upon detection of the connecting knot by the detection device, so that one false twist texturing finished product is corresponded to a plurality of spinning finished products. On this basis, the complete original origin of the false twist texturing product is obtained and recorded.
Further, as the preferable information of the position information of the spinning finished product, a second technical solution is that the position information of the spinning finished product includes original position information of the spinning finished product and placement information of each spinning finished product on the creel. The information on the origin position of the finished spun product is information on the production of the finished spun product, for example, produced at a certain time in a workshop of a certain upstream spinning factory. The placement information is the position information of the spinning finished product on the raw silk frame, namely the position of each raw silk frame. The matching module matches the position of the original filament frame with the winding position of the false twist texturing machine.
In order to facilitate the input of the information, the third technical scheme is that each spinning finished product corresponds to a spinning finished product identification label; and each raw silk position of the raw silk rack for placing the spinning finished product corresponds to one position identification label. The identification device can directly carry out identification entry on the identification label.
The fourth technical proposal is that the machine controller is provided with a display interface for displaying the matching information. The display interface can visually display the matching relationship between the spinning finished product and the false-twist textured finished product, and is convenient for operators to directly obtain.
Likewise, in order to solve the technical problems of the prior art, a fifth technical solution provides a method on a false twist texturing machine for correlating spinning product data and false twist texturing product data, wherein an identification device in communication with the machine controller is used to identify and enter the data, said correlation method comprising in sequence the following steps: firstly, the identification equipment records position information of a spinning finished product; secondly, the recorded position information of the spinning finished product is transmitted to the machine controller; thirdly, after the production of the false twist textured finished product is started, the machine controller establishes matching between the position information of the false twist textured finished product and the position information of the spinning finished product; detecting a connection node between adjacent spinning finished products by a detection device communicated with the machine controller, and transmitting connection node information to the machine controller; and fifthly, the machine controller updates the matching relation between the position information of the false twist deformation finished product and the position information of the spinning finished product based on the connection information.

Detailed Description
The false twist texturing machine has the functions of sequentially carrying out necessary yarn treatment on the yarn of the spun finished product and finally winding and shaping the yarn to obtain the false twist textured finished product. The spun product as the starting material for the false twist texturing machine is produced by a spinning device located upstream of the false twist texturing process. The spinning equipment filters, spouts and cools the melt to form yarns, and oils and winds the yarns to form the finished spinning products. The spun product needs to be further processed in the false twist texturing machine to obtain a yarn with certain characteristics, which can be directly used in the downstream weaving process. Each false twist texturing machine has hundreds of working positions, and each working position processes one yarn independently.
FIG. 1 schematically shows a false twist texturing machine as claimed in the present disclosure and schematically shows a system with correlation for correlating spinning finish data and false twist texturing finish data. This embodiment shows only four working bits. The reference numeral 13 indicates a former, and the structure of the former 13 is shown only schematically here. The raw silk frame 13 is provided with a plurality of raw silk positions 1L, 1R, 2L, 2R, 3L, 3R, 4L and 4R, and each raw silk position is provided with a spinning finished product. The yarn of the finished spinning product is drawn off under the active conveying action of the first conveying device 2. In this embodiment, the first transport device 2 is designed in a clamping manner, and the thread is transported between two rollers which are pressed against one another. The drawn yarn is then subjected to heat treatment in a heat treatment apparatus 3, and the heat-treated yarn is subjected to cold treatment in a cold treatment apparatus 4. The false twist processing device 5 is located downstream of the cold processing device 4 and false twists the yarn. Under the combined action of the heat treatment device 3, the cold treatment device 4 and the false twist treatment device 5, the yarn obtains the crimp characteristic. Subsequently, the yarn enters the second transport device 6. The structure of the second conveyor 6 is similar to the structure of the first conveyor 2, and the conveying speed of the second conveyor 6 is faster than the conveying speed of the first conveyor 2, thus having a stretching effect on the yarn. Finally, the yarn is wound and formed on a winding device. The structure and principle of the above listed yarn treatment devices are known in the art of false twist texturing and will not be described in detail.
In order to improve the continuity of the false twist texturing process and avoid unnecessary repeated operations, a plurality of finished spun yarns are connected end to form a continuous finished spun yarn output. As shown in fig. 1, two finished spinnerets 1.1.1 and 1.1.2 are connected end to end and placed at the strand positions 1L and 1R of the strand rack 13, respectively, wherein the finished spinnerets 1.1.1 are located at the strand position 1R, and the finished spinnerets 1.1.2 are located at the strand position 1L. A connecting knot is formed at the joint of the two spinning finished products 1.1.1 and 1.1.2. The spun product 1.1.2 at the strand position 1L is unwound first into the first conveying device 2 and subsequently into the processing device. After the unwinding of the spun product 1.1.2 is completed, the spun product 1.1.1 at the strand position 1R is unwound, so that the raw material for the production of the false-twist textured product 7.1 can be supplied without interruption. Due to this, it may happen that one false twist textured finish is processed from several different spun finishes. In tracing back the original origin of the false twist textured product, special consideration must be given to this situation to ensure that complete historical data is obtained.
Based on the above technical background, the false twist texturing machine of the present invention further has a machine controller 10 and an association system for associating the spinning finish data and the false twist texturing finish data. Not explicitly shown in the figures, the machine controller 10 can be used as a general control terminal for the false twist texturing machine for individual and/or zonal control and monitoring of all the thread treatment devices of the false twist texturing machine. The correlation system comprises an identification device 9 electrically connected to the machine controller 10, detection means 8.1 to 8.4 and a matching module 11 built into the machine controller 10.
Fig. 2 schematically shows a partial schematic view of the strand position of the creel with the finished spun product placed thereon. In the production completion stage of the spinning finished product, the inner side of the bobbin of the spinning finished product is stuck with a unique spinning finished product identification label 15. The spinning product identification tag 15 encodes the original position information of the spinning product, such as the manufacturer information and the finish time information of the spinning product. The information of the original position of the finished spinning product can be read by the identification device 9. Each strand position of the filament support 13 is attached with a unique position identification label 14. The position identification tag 14 encodes position information of the filament position, for example, 1L is a filament position at which a spun product to be unwound first is placed at a first working position, and 1R is a filament position at which a spun product connected to the spun product at 1L is placed at the first working position; 2L and 2R are protofilament positions of a second working position; 3L and 3R are protofilament positions of a third working position; 4L and 4R are protofilament positions of the fourth working position.
The identification device 9 is preferably hand-held and can communicate wirelessly with the machine controller 10 via a network. After the spinning product is placed on the filament position of the filament rack 13, the identification device 9 may identify and record the spinning product identification tag 15 and the position identification tag 14, and transmit the spinning product position information to the machine controller 10.
After receiving the position information of the finished spun product, the matching module 11 of the machine controller 10 will establish a match between the position information of the false twist textured finished product and the position information of the finished spun product, so as to obtain a correspondence between the false twist textured finished product and the finished spun product, for example, currently, only the finished spun product 1.1.2 is used to produce the false twist textured finished product 7.1. If the finished spun product 1.1.2 is sufficient for the production of two false twist texturing products, historical data such as delivery information of the finished spun product 1.1.2 can be traced back when the quality of the false twist texturing product 7.1 and the quality of the other false twist texturing product are of low grade.
Furthermore, a detection device 8.1, 8.2, 8.3, 8.4 is assigned to each work station, which is arranged between the two connected spinning products, for example, the detection device 8.1 is arranged between the spinning product 1.1.1 and the spinning product 1.1.2. The connection between the end product 1.1.1 and the end product 1.1.2 is located upstream of the detection device 8.1, according to the direction of advance of the yarn. The yarn passes through the detection device 8.1, so that the detection device 8.1 detects the connecting knot in real time. Once the detection device 8.1 detects the connection, the detection device 8.1 sends an electrical signal to the matching module 11 of the machine controller 10, so that the matching module 11 updates the matching relationship between the position information of the finished spun product and the position information of the false-twist textured finished product, and further obtains a new corresponding relationship between the false-twist textured finished product and the finished spun product. For example, after the detection device 8.1 detects the connection between the finished spun product 1.1.1 and the finished spun product 1.1.2, it can be concluded that the finished spun product 1.1.1 and the finished spun product 1.1.2 are jointly used for producing the false-twist textured product 7.1, so that when a quality problem is found in the false-twist textured product 7.1, historical data such as the factory information of each of the two finished spun products 1.1.1, 1.1.2 can be traced back. In the same way, it can be seen that spun products 1.2.1 and 1.2.2 are used together to produce false twist texturing product 7.2, spun products 1.3.1 and 1.3.2 are used together to produce false twist texturing product 7.3, and spun products 1.4.1 and 1.4.2 are used together to produce false twist texturing product 7.4.
In order to be able to visually display the correspondence between the finished spun yarn and the false-twist textured yarn, the machine controller 10 is provided with a display interface 12 for displaying the matching information.
The identification mode of the identification device 9 may be a scanning identification two-dimensional code or a bar code, or a near field communication identification mode.
In addition, the method for correlating the spinning product data and the false twist texturing product data according to the invention comprises the following steps:
as a first step, a spinning finished product identification tag 15 is attached to the inner side of a bobbin of the spinning finished product, the spinning finished product identification tag 15 encodes the original position information of the spinning finished product, such as delivery information of the spinning finished product, and the operation is usually completed in a spinning production area; meanwhile, each strand position of the strand frame 13 is attached with a position identification label 14, and position information of the strand position is encoded to define the sequence of the strand position in the whole false twist texturing machine. Different strand positions for providing continuous yarns to the same working position are defined as belonging to the same group. In the example of 2L, 2R, one finished spin product 1.2.2 on 2L first provides the yarn for the second working position, and subsequently one finished spin product 1.2.1 on 2R subsequently provides the yarn for the second working position after the previous finished spin product 1.2.2 is unwound.
As a second step, the identification device 9 communicating with the machine controller 10 is used to sequentially identify and record the spinning finished product identification tag 15 and the position identification tag 14 corresponding to the raw yarn position where the spinning finished product is placed, and record the position information of the spinning finished product, wherein the position information of the spinning finished product comprises the original position information of the spinning finished product, namely the delivery information, and the placement information of each spinning finished product on the raw yarn rack, namely the corresponding raw yarn position information;
as a third step, after the production of the false-twist textured finish product is started, the matching module 11 of the machine controller 10 establishes a matching relationship between the position information of the false-twist textured finish product and the position information of the spun finish product, thereby establishing a corresponding relationship between the false-twist textured finish product and the spun finish product used for producing the false-twist textured finish product;
as a fourth step, the detection device 9 communicating with the machine controller 10 detects a connection node between adjacent spinning finished products in real time, and transmits connection node information to the machine controller 10;
as a fifth step, the matching module 11 of the machine controller 10 updates the matching relationship between the position information of the false-twist textured final product and the position information of the spun final product based on the connection information, and further updates the corresponding relationship between the false-twist textured final product and the spun final product used for producing the false-twist textured final product.
As a sixth step, the display interface 12 of the machine controller 10 displays the correspondence between the finished spun yarn and the finished false twist textured yarn.
Establishing the matching relationship and updating the matching relationship in real time can help trace the whole historical data to find a possible problem source.
