Description

False twisting machine with empty paper tube feeding device Technical Field The present invention relates to a false twist machine having a blank tube supply device for supplying a blank tube to a winding device. Background Patent document 1 discloses a false twisting machine for performing false twisting on a yarn. The false twisting machine of patent document 1 includes a yarn feeding section, a yarn feeding roller for advancing a yarn fed from the yarn feeding section, a winding device for winding the advancing yarn, a heating device, a cooling device, and a false twisting device arranged in a yarn path from the yarn feeding section to the winding device. In the false twisting machine, the yarn fed from the yarn feeding portion is false twisted by a false twisting device or the like, and wound around a paper tube by a winding device, thereby forming a package. After the package having been fully wound is removed from the winding device and the empty paper tube in a state where the wire is not wound is attached to the winding device, the wire is wound again by the winding device. Patent document 2 discloses a blank tube supply device (bobbin replacing device) for supplying a blank tube (blank bobbin) to a winding device such as a false twisting machine. The empty paper tube supply device is capable of storing empty paper tubes, and when the yarn is wound on the paper tubes by the winding device to become a full-wound package, the full-wound package is removed, and the empty paper tubes are supplied from the empty paper tube supply rail to the winding device. Patent document 1 Japanese patent application laid-open No. 2011-47074 Patent document 2 Japanese patent laid-open No. 10-279188 The empty paper tube feeding device is appropriately replenished with empty paper tubes by an operator, an automatic robot, or the like. Here, when the empty paper tube stored in the empty paper tube supply device is used up but the empty paper tube is forgotten to be replenished, the empty paper tube cannot be supplied from the empty paper tube supply device to the winding device. In the false twisting machine, the yarn is continuously fed from the yarn feeding section. Therefore, if the empty paper tube is not fed to the winding device after the full package is removed from the winding device, the wire is continuously fed from the wire feeding portion, and thus there is a possibility that the wire may be wound around the winding device. In addition, when a break in the winding of the wire, a failure in the yarn hanging to the winding device, or the like occurs, the winding of the winding device may be interrupted in the middle to request the next blank tube in advance. In this case, when the blank tube is not stored in the blank tube feeding device, the above-described problem may occur, and it is necessary to grasp the timing of replenishing the blank tube to the blank tube feeding device. In particular, in a false twisting machine having a plurality of winding devices, it is difficult to grasp timing of replenishing the blank tube for all blank tube feeding devices corresponding to the respective winding devices, and it is easy to forget to replenish the blank tube. Disclosure of Invention The invention aims to provide a false twisting machine, which can inhibit forgetting to supplement a blank pipe to a blank pipe supply device and inhibit a winding device from generating winding failure of a silk thread. A false twist processing machine is provided with a plurality of winding devices for winding a yarn around a paper tube to form a package, a plurality of blank tube supply devices provided for the winding devices, respectively, for supplying the blank tubes to the winding devices, and a control unit having a storage unit capable of storing the plurality of blank tubes and at least one sensor for detecting that the number of the blank tubes stored in the storage unit is equal to or less than a predetermined number, wherein the control unit generates a notification signal for notifying the storage unit that the blank tubes need to be replenished when the number of the blank tubes stored in the storage unit is detected by the at least one sensor to be equal to or less than the predetermined number. According to the present invention, since the empty paper tubes can be replenished to the storage unit based on the notification signal, the timing of replenishing the empty paper tubes can be grasped for all the empty paper tube supply devices corresponding to the plurality of winding devices. This can prevent the empty paper tube from being forgotten to be supplied to the empty paper tube supply device, and prevent the winding device from causing winding failure of the yarn. In the present invention, it is preferable that the at least one sensor includes a 1 st sensor that detects that the number of stored empty tubes stored in the storage unit is equal to or less than a 1 st predetermined number, which is a 1 st predetermine
