Description

Roll body replacement system

One aspect of the present invention relates to a system for replacing a package body.

A false twisting machine is known, which performs false twisting processing on a plurality of synthetic fiber yarns supplied from a self-supplied yarn package, and winds the processed synthetic fiber yarn in a winding device to form a winding package ( For example, Patent Document 1: Japanese Patent Laid-Open No. 6-200434). The false twisting machine is used in a creel that holds a plurality of yarn-feeding packages, and the Pegs that hold the yarn-feeding packages are used in groups of two to continuously feed synthetic fiber yarns. In this configuration, the synthetic fiber yarn supported on the inner side of the yarn feeding package of one insert and the synthetic fiber yarn supported on the outer side of the yarn feeding package of the other insert are connected. Thereby, in the creel, even if the synthetic fiber yarn of one yarn supply package is used up, the synthetic fiber yarn is supplied from the other yarn supply package, so that the synthetic fiber yarn can be continuously supplied.

In this configuration, when the synthetic fiber yarn of the yarn feeding package is used up, a new package needs to be supplied, and the synthetic fiber yarn of the yarn feeding package supported by an insert is required to be supported in The connection of the synthetic fiber yarn in the yarn-feeding package of another insert. Such wiring work (tailing work) is generally performed manually. Patent Document 2 (Japanese Patent Publication No. 7-68010) discloses a work trolley, which is installed along the creel so as to be able to travel, and is used for the operations of replacing and connecting the yarn package body Ride.

Patent Document 2 discloses a package replacement system (yarn feeder replacement system), which is used to detect the diameter of the yarn feeder package held on the creel in three stages (full yarn, half yarn, small yarn) The sensor is installed on the work trolley. As a result, the operator can judge that the yarn does not need to be replaced when it is full, it is about to be replaced when it is half, and it needs to be replaced when it is small, so that it can be held on the creel efficiently. The replacement and wiring of the yarn-feeding package body.

However, in the aforementioned previous package replacement system, the state of the yarn package can be determined only at the moment (sensing moment) detected by the sensor installed on the work trolley. Therefore, if the time between sensing becomes longer, there are situations in which the synthetic fiber yarn of the yarn feeder package is about to be used up, and the synthetic fiber yarn of the yarn feeder package has been used up.

Therefore, an object of one aspect of the present invention is to provide a package replacement system that can perform the replacement operation and the connection operation of the yarn supply package more efficiently.

The package replacement system of one aspect of the present invention is used in a textile machine. The textile machine is provided with a creel, which is supported by a yarn feeder package formed by winding a synthetic fiber yarn containing synthetic fibers on a tube A yarn-feeding package support part; a processing device that processes the synthetic fiber yarn supplied from the self-supplied yarn package; and a winding device that winds the synthetic fiber yarn that has been processed to form a winding package; And the package replacement system is provided with: a walking unit, which is movably installed in one direction along the creels arranged in one direction; a walking control part, which controls the walking of the walking unit; and an acquisition part, which is installed in the walking unit, Obtaining the remaining amount of synthetic fiber yarn wound on the yarn feeder package held on the creel; and a predicting unit that predicts the amount of synthetic fiber yarn from the yarn supplying package based on the remaining amount of synthetic fiber yarn acquired by the acquiring unit When the synthetic fiber yarn in Zhongzhi runs out.

In the package replacement system of this configuration, since the remaining amount of the yarn wound on the yarn feeder package is acquired during sensing, it can be grasped in more detail compared to the case of acquiring the state of the yarn in three stages The state of the yarn package body. Furthermore, in the package replacement system of this structure, since the time point when the yarn in the yarn supply package is used up is predicted based on the remaining amount of the obtained yarn, the time point of sensing is not limited, and the yarn supply is always grasped. The state of the package body. As a result, it is possible to more efficiently perform the replacement of the yarn supply package and the connection work.

In the package replacement system of one aspect of the present invention, the acquisition unit may be a sensor that detects the distance to the outer peripheral surface of the package along the diameter direction of the package, and the prediction unit is based on The distance detected by the sensor predicts the time when the synthetic fiber yarn in the package body is used up. In this structure, the position of the outermost layer of the package, that is, the diameter of the package, can be obtained by a simple structure. As long as the diameter of the package body can be obtained, the remaining amount of yarn can be predicted by simple calculation.

In the package replacement system of one aspect of the present invention, the traveling control unit can also move the traveling unit by obtaining the above-mentioned distances of all the packages held on the creel at a fixed time interval. In this configuration, since the remaining amount of yarn is obtained at a fixed time interval, the time point when the yarn in the yarn supply package is used up can be predicted more accurately.

In the package replacement system of one aspect of the present invention, the walking unit may also have: a wiring device that connects the yarn ends of the yarn feeding package to each other; and a guiding device that connects the yarn of the yarn feeding package to each other. The end is guided to the wiring device; and the replacement device, which supplies the yarn feeding package to the creel, and recovers the bobbin from the creel. Thereby, the replacement operation and the connection operation of the yarn feeding package can be performed by the walking unit without the use of human hands.

In the package replacement system of one aspect of the present invention, the traveling control unit can also move the traveling unit to the replacement position of the yarn supply package predicted to be used up by the synthetic fiber yarn based on the above-mentioned time point predicted by the prediction unit . Thereby, the replacement operation and the connection operation of the yarn feeding package can be performed more efficiently.

In the package replacement system of one aspect of the present invention, the predicting part and the walking control part may also be provided in the walking unit. In this configuration, a package replacement system can be provided as a traveling unit.

The package replacement system of one aspect of the present invention may further include a determination unit that determines whether or not the winding package includes a wire connection part based on the prediction result of the prediction unit. Here, there are cases where the synthetic fiber yarn wound as a winding package includes a wire connection part and a case where the wire connection part is not included, and there are cases where it is classified into ranks (levels). In this structure, it is possible to easily distinguish higher-level winding packages.

According to one aspect of the present invention, the replacement operation and the connection operation of the yarn supply package can be performed more efficiently.
