摘要： An object of the present invention is to reduce power consumption.
A first heater 13 is provided with a yarn running groove, and includes: a heating unit configured to heat a yarn running in the yarn running groove; three heat insulating blocks which extend along an extending direction and which are aligned in a base longitudinal direction so as to oppose an open end, i.e., a lower end of the yarn running groove; and closing members 79, side plates 63a, side plates 63b, and central plates 64 each of which are provided on both sides of the heat insulating blocks in the extending direction. In this regard, gaps between the side plates 63a, the side plates 63b, and the central plates 64 form slits 67 through which the yarn passes when the yarn is inserted into the yarn running groove. When viewed in the extending direction, the slits 67 are provided to oppose paths formed between the adjacent heat insulating blocks. The closing members 79 are movable between a close position where the slits 67 are closed and a retracted position where the slits 67 are not closed.

摘要： Provided is a tension abnormality detection device (10) capable of accurately detecting various abnormalities related to tension of a thread wound by a thread winding machine (1), with a simple method. The tension abnormality detection device (10) includes a control device (50) and a tension sensor (13) for detecting the tension of the thread wound by the thread winding machine (1). The control device (50) executes processing for acquiring an autoencoder (124) trained to compress a normal tension waveform and then restore the normal tension waveform, and processing for detecting abnormality in the tension of the thread wound by the thread winding machine (1), based on a degree of similarity between an input tension waveform obtained from the tension sensor (13) and an output tension waveform obtained by inputting the input tension waveform to the autoencoder (124).

摘要： The efficiency in yarn threading is improved when yarn threading to yarn guides of a pair of winding units is performed. Each of paired winding units 5 of a spun yarn take-up machine 1 includes fulcrum guides 20 aligned in a front-rear direction. The spun yarn take-up machine 1 includes a yarn threading mechanism 30 configure to perform yarn threading to the fulcrum guides 20. The yarn threading mechanism 30 includes paired holding units 31 which are provided to correspond to the respective winding units 5 and are configured to hold respective groups of yarns Y and a drive mechanism 32 configured to the move the paired holding units 31. The drive mechanism 32 moves the paired holding units 31 from capturing positions where the yarns Y can be captured to yarn threading start positions that are rearward of the capturing position and further moves the paired holding units 31 to yarn threading completion positions that are forward of the yarn threading start positions, so as to thread all of the yarns Y to the fulcrum guides 20.
