位置Aに移動させる。(Prior Art) FIG. 1 shows a conceptual diagram of a general turret type winder. First of all, to explain the general concept of a turret type winder with reference to Fig. 1, the web 1 is wound around the winding core 2 at position A, and the winding length is detected by a winding length counter (not shown) until the full amount is reached. Then, the turret 4 is reversed in the direction of arrow C by a turret drive device (not shown), and the winding core 2 is moved to position B and the winding core 3 is moved to position A.

トロールする必要がある。 Next, the web 1 is wound around the core 3 newly supplied to the winding position A using a web 1 cutting device and rewinding device (not shown), and the web 1 is continuously wound. When winding the web 1 at position A, in order to obtain a good winding appearance without causing wrinkles in the web 1, it is necessary to apply an appropriate web tension according to the winding diameter of the web 1, which increases every moment. For this purpose, it is necessary to precisely control the output of the core shaft drive motor 6 in the conventional turret type winder shown in Fig. 3 by making it correspond to the rotation speed of the core shaft 5 corresponding to the web winding diameter. There is.

ている。 In the conventional winding machine shown in FIG. 3, in which a core shaft drive motor 6 is mounted on a turret 4, the rotation speed of the core shaft 5 is the same as that of the pulse generator 7 attached to the core shaft drive motor 6. It was detected by a pickup 8 mounted on the turret 4 opposite the pulse generator 7. For this reason, the core shaft rotation speed signal from the pickup 8 is sent to a core shaft drive motor control device (not shown) through the wiring of the pickup 8 and the slip ring 9.

化し、操作、保守点検等に不便を来たしていた。(Problem to be solved by the invention) In this way, in the conventional turret type winding machine, the pick-up 8 for detecting the rotation speed of the winding core shaft 5 is also provided on the rotating turret 4. Since the core shaft rotational speed number is transmitted via the slip ring, the reliability of the control system is low and the service life is likely to be shortened, and furthermore, installation space for the rotation speed detector and the slip ring 9 is required. As a result, the winding machine itself has become larger rather than more compact, which has caused inconvenience in operation, maintenance, and inspection.

ものである。(Means for solving the problem) Therefore, in the present invention, a plurality of cores are attached to a pair of turrets, and after the web is fully wound, the turret is rotated by a certain amount, and the web is re-wound onto a new core. In a turret type winder that continuously winds the web,
A core shaft drive motor is attached to each of the plurality of core shafts on the turret, a pulse generator is provided on the motor, and a non-contact type motor is installed at a position facing the pulse generator and connected to a member outside the turret. In addition to fixing the rotation speed detection device, the device has a control device that directly receives a detection signal of the core shaft rotation speed detected by the detection device and controls the drive motor. It is intended as a means of

That is, the rotational speed detection device 10 is fixedly provided on a frame portion or the like outside the turret 4,
Moreover, it is installed at a position opposite to the pulse generator 7 at the web 1 winding position A (FIG. 1). As this rotation speed detection device 10, a publicly known non-contact rotation speed detection device that is commercially available is used, and the detection device 10 and a core shaft drive motor control device (not shown) are directly connected by a signal line. .
