Description

Description: TECHNICAL FIELD The present invention relates to a yarn winding machine which mounts a plurality of bobbins on one bobbin holder and winds the yarn around these bobbins at a high speed.

(Prior Art) Conventionally, in this type of yarn winding machine, for example, a chuck for gripping a bobbin is provided on a bobbin holder, and each bobbin is detachably supported on the bobbin holder. In such a yarn winding machine, if the bobbin is rotated without forgetting to attach the bobbin to the holder, the segments of the chuck may be damaged or scattered by centrifugal force, which is very dangerous. For this reason, there has been proposed a yarn winding machine which detects whether or not a bobbin is mounted, and for example, a yarn winding machine disclosed in Japanese Patent Application Laid-Open No. 51-26344 is known. In this apparatus, the presence / absence of a bobbin is detected based on the amount of claw movement of a chuck. In addition, there is a device in which a device for detecting the presence or absence of each of a plurality of bobbins is separately provided from the yarn winding machine.

(Problems to be solved by the invention) However, in the former conventional yarn winding machine,
Since the presence / absence of the bobbin is indirectly detected based on the amount of movement of the chuck jaw, the movement of the chuck jaw varies due to the variation in the inner diameter of the bobbin, and the detection of the presence or absence of the bobbin becomes inaccurate. was there.

Further, in the latter conventional yarn winding machine, since a device for detecting the presence or absence of each bobbin is provided separately from the yarn winding machine, there is a problem that the cost is increased. .

(Object of the Invention) Accordingly, the present invention provides a yarn winding machine that can reliably detect the presence or absence of a bobbin at a low cost by providing a detection unit that can detect the presence or absence of each bobbin in a support unit. It is intended to provide.

(Means for Solving the Problems) In order to achieve the above object, the present invention has a chuck for gripping at least one bobbin, detachably supports the bobbin with the chuck, and is driven to rotate to thread the bobbin. A bobbin holder for winding the yarn, and a support means for pushing out the bobbin and a package made of the yarn wound on the bobbin by a predetermined amount from the bobbin holder to the front of the winder to removably support the package. In a yarn winding machine in which an empty bobbin is attached to a bobbin holder after the bobbin is removed, the supporting means has a detecting means capable of detecting the presence or absence of the bobbin supported by the bobbin holder for each bobbin. The detection means detects that an empty bobbin is attached to the bobbin holder after the package is removed. It is a sign.

(Operation) In the present invention, after the package is removed from the support means, the detection means directly detects that an empty bobbin is attached to the bobbin holder for each bobbin, and the bobbin is securely attached before the bobbin holder starts rotating. Is detected.

Further, since the supporting means has the detecting means, it is not necessary to provide the detecting means separately from the yarn winding machine, and the cost is reduced.
