Spun yarn winding device and spun yarn winding facility

Abstract

Provided is a spun yarn winding device compact in the vertical direction. A spun yarn winding device is provided with: a machine body (12); a turret (16); a feeding roller (22) which is affixed in position relative to the machine body (12), is not in contact with a winding bobbin (B), and feeds yarn (Y) to the winding bobbin (B) at a speed equal to or higher than the speed at which the yarn (Y) is wound on the winding bobbin (B); a traverse device (32) which is affixed in position upstream of the feeding roller (22) with respect to the advance direction of the yarn (Y) and which traverses the yarn (Y); a peripheral speed detection unit (42) for detecting the peripheral speed of the winding bobbin (B); and a control unit (14) which, during a yarn winding period (P), performs basic operation for maintaining the free length (FL1) of the yarn (Y) at a basic length (FL11) by controlling the rotational angle of the turret (16), the free length (FL) being the length of the portion of the tarn (Y) which is located between the feeding roller (22) and the winding bobbin (B).

Description

Technical field [0001] The present invention relates to the technology of a spinning winding device and a spinning winding device for winding a spun yarn on a winding bobbin. Background technique [0002] Conventionally, a traverse device provided with a traverse guide that reciprocates in the axial direction of the winding bobbin is provided in a spinning winding device. A contact roller in contact with the package is provided below the traverse device. If the winding bobbin is rotated to increase the thickness of the package while winding the yarn reciprocally, the position of the contact roller rises corresponding to the increase in the winding thickness of the package (巻き太り). Therefore, we have known a technique that raises the touch roller and the traverse device together in response to the thickening of the winding of the package, and fixes the relative positions of the touch roller and the traverse device to the package (see, for example, Patent Document 1). [0003] On th...

Problems solved by technology

[0010] However, in the above-mentioned conventional spinning winding device, it is necessary to gradually raise the touch roller and the traversing device in accordance with the increase in the winding thickness of the package, and in order to eliminate the phenomenon of protrusion on both sides of the package, there is a need to move the traversing device. It is necessary for the moving device to rise significantly relative to the contact roller

The above-mentioned conventional spun winding device has the problem that the longitudinal dimension of the spun winding device cannot be kept small because the movable portion protruding upward is provided in this way.

[0011] In addition, since the longitudinal dimension is large, if a layout in which a plurality of spun winding devices are stacked in the vertical direction is adopted, the height of the spun winding device becomes high, and the operation of the upper spun winding device is greatly affected. particularly low sex

Therefore, there is also a problem that the layout in which a plurality of spinning winding devices are stacked in the vertical direction cannot be adopted, and the space cannot be effectively used.
