Description

[Detailed Description of the Invention] This invention relates to a turret type winding machine in which a plurality of winding spindles are driven by a drive motor placed on a machine frame.

Conventionally, a turret type winder has a turret rotor that is rotatably held on a spindle on a winding machine stand, and a plurality of winding spindles are cantilever-supported. When the spindle is full, the turret rotor rotates and moves the other empty take-up spindle to the winding position, transferring the strand from the full take-up spindle to the empty take-up spindle and continuously rolling the strand. Although it is configured to be capable of winding, the number of drive motors that drive each winding spindle are generally integrally attached to the turret rotor itself, corresponding to the number of winding spindles. .

In other words, the shaft of the winding spindle and the drive shaft of the drive motor (
output shaft) is directly connected.

Therefore, as described above, when the turret rotor rotates, each drive motor also rotates together with the turret rotor.

Therefore, the power supply for the drive motor needs to supply power to the rotating turret rotor via a slip ring mechanism, and there is no way to branch the drive when driving the traverse device and the winding spindle synchronously. So,
Conventionally, electrical methods, that is, synchronization by controlling the drive motors of both wheels using an inverter or by using a pulse motor, have been mainly used, but not only do they not provide sufficient synchronization accuracy, but these methods are extremely difficult to achieve. It was an expensive device and required advanced knowledge for maintenance.

Furthermore, since a heavy drive motor is integrally attached to the turret rotor, the weight of the turret rotor becomes considerably heavy, and a large-capacity drive source is required to drive the reverse rotation of the turret rotor.

In addition, a considerable amount of turning space was also required.

This invention solves all of the drawbacks of the conventional turret type winding machine mentioned above.The key point is that the drive motor is installed in the machine frame, and the drive motor is installed in the frame of the machine. The winding spindle and the traverse device are synchronized by driving the traverse device via the winding spindle.

The turret type winder of this invention will be explained below with reference to the embodiments shown in the drawings.

Fig. 1 is a plan view of the turret type winder of this invention, Fig. 2 is a diagram of the winding drive system, Fig. 3 is a rear view of the same, Fig. 4 is a side view of the same, and Fig. 5 is a front view of the same. It is a diagram.

In the figure, 1 and 1' are cantilever-supported by a turret rotor 1 which is held so as to rotate (revolution) about a support shaft 2 with a winding spindle, and therefore the turret rotor T
It rotates together with the rotation of.

As shown in FIGS. 3 and 4, the turret rotor T is driven by a drive motor 28 installed on the machine base 2T via a speed reducer 29, a sprocket 30, a chino 31, a sprocket 32, and a gear 33. This is accomplished by transmission of teeth 34 carved on the outer periphery of the turret rotor.

At this time, the positioning of the turret rotor T after rotation is performed accurately by a known positioning means 8 attached to the upper part of the turret rotor support frame.

The driving of the winding spindles 1, 1' will be described later.

Reference numeral 5 denotes a traverse device, which, as is well known, has a traverse drum 6 having a cam groove formed on its outer periphery, and a sliding device that engages with the cam groove to convert the rotational motion of the traverse drum 60 into reciprocating motion, hooking the strand and traversing it. It is attached to the machine frame 10 parallel to the winding spindle 1' at the winding position A.

The driving of this traverse device 5 will also be described later.

Reference numeral 9 denotes a line removal guide, which is not shown, but when the winding spindle 1' at the winding position A becomes fully wound, the turret rotor T rotates and another empty winding spindle 1 is moved to the winding position A. When the strand is moved, the strand from the full winding spindle 1' is transferred to the empty winding spindle 1 by the strand transfer mechanism. It plays a role.

That is, when the winding spindle 1' is fully wound, it protrudes forward (to the right) from the position shown in the figure (Fig. 4), removes the strand from the traverse device 5, and further protrudes and is placed opposite and adjacent to the tip of the winding spindle 1'. It guides the strand to a provided waist roller (not shown).

As is already well known, this ejection operation is performed by an air cylinder (not shown), and its sequence is also known.

4.4' is a drive motor for the aforementioned winding spindles 1, 1' and the traverse device 5, which is placed on the machine frame 10.

Therefore, it does not rotate together with the turret rotor 7 as in the conventional case.

The drive transmission system in the winding spindles 1, 1' and the traverse device 5 will be explained below.

Next, the drive transmission system of the winding spindles 1, 1' will be explained.

First, the winding spindle 1 is rotated by a drive motor 4, and the rotation of the drive motor 4 is caused by a timing pulley 14 on the drive motor side, a timing pulley 13 rotatably supported on the support shaft 2 of the turret rotor 7, and a timing pulley 13 rotatably supported on the support shaft 2 of the turret rotor 7. The timing belt is folded between the timing pulley 12 integrated with the pulley 13 and the winding spindle side tying pulley 11 attached to the rear end of the shaft of the winding spindle 10 (
The winding spindle 1' is transmitted from the drive motor 4' to the drive motor side timing pulley 18, the relay timing pulley 17, and this timing pulley 1T. Integrally connected relay timing pulley 1
6 and a timing belt (toothed belt) interposed between the winding spindle side tying pulley 15 attached to the rear end of the winding spindle 1'. .

As is clear from the drawing, the two relay timing pulleys 12, 13 and 17, 18 are supported concentrically with respect to the support shaft 2 and rotatably (including relative rotation) with respect to each other. This ensures that the turret rotor 7 rotates in one direction.

This point is a feature of this idea.

Each winding spindle 1, 1' is not always driven, but only the winding spindle 1' in the winding position A is driven.

The drive motors 4, 4' include variable speed motors, the rotational speed of the spindle 1.1' in the case of universal motors can be set by means of a timing pulley 14.18 or a timing pulley 11.15.

In addition, if a slight change in load fluctuation is acceptable, it is also possible to drive each winding spindle with one drive motor by installing a mechanical clutch on the timing pulleys 11 and 15 of each winding spindle. .

Next, to explain the drive of the traverse device 5, the timing pulley 1 provided coaxially with the timing pulley 14, 18 for driving the spindle is connected to the drive motor 4, 4'.
9, 20, timing pulleys 21 to 25 and a timing pulley 26 attached to the shaft end of the traverse drum 6
It is driven by the transmission of the timing pulley (toothed belt) that is hung between the timing pulley and each timing pulley.
In particular, this drive transmission system is connected to the two drive motors 4, 4' by a timing belt, and therefore a clutch 35° 35' is installed on the timing pulleys 21, 22.

That is, in the illustrated embodiment, the clutch 35 of the tying pulley 21, which is in communication with the drive motor 4 on the non-operating side, is released (
The timing pulley 21 is in a free state.

Therefore, what is currently driving the traverse device 5 is
This is a transmission system of a timing pulley 22 that communicates with a drive motor 4' which is driving the winding spindle 1' at the winding position A.

When the turret rotor 7 is reversed and the take-up spindle is switched, the operating states of the drive motors 4, 4' are also changed, so naturally the opening and closing of the clutches 35, 35' are also reversed.

The clutches 35, 35' can be easily controlled by appropriate means, and it is also possible to control them in a sequence using an electric clutch or a hydraulic clutch.

As described above, in the turret type winder of this invention, the drive motor is not attached to the turret rotor but is placed on the machine frame, so the power supply slip ring mechanism that was previously required is no longer required, and the drive motor Since the turret rotor does not rotate (reverse) with the turret rotor, it depends on the model, but about 1
OOKI! Since the considerable weight can be reduced, the motor for driving the rotation of the turret rotor can be lowered by one rank, and combined with the removal of the slip ring mechanism, the width and depth of the machine platform can be reduced accordingly, allowing for effective use of installation space. It is something.

In addition, since each spindle is driven by an independent motor, there is no negative influence from the load or power supply side, and there is no unevenness in the fineness of the winding strand.Furthermore, each timing pulley rotates at a high speed of 7000 rpm on the spindle shaft. However, the rotation of the drive motor and the turret rotor on the support shaft can be kept approximately at around the motor synchronous speed, thereby reducing the influence of GDZ on the rotating part and extending the life of the bearing.

Needless to say, the structure has also become simpler.

Furthermore, since the turret type winder of this invention can reliably synchronize (mechanically) the traverse device and the winding spindle, it is possible to obtain square end cheese with a good shape. The synchronization mechanism is simple and much cheaper than electrical synchronization methods.
Furthermore, as a matter of course, there is no need for a drive motor for traverse, which is economical.

In addition, in the case of this invention, since the turret rotor can rotate in one direction, the changeover is performed smoothly when changing the winding. The operating mechanism is simple, the winding bobbin is also simple in structure, the overall configuration of the winder is significantly simplified, and a winder with excellent winding operation is provided.
