Description

The present invention relates to a winding device for a revolving type winding machine.

(Prior Art) When a pair of mandrels (1a) (1b) are arranged at a winding position A and a standby position B, and the winding layer on the mandrel (1a) at the winding position reaches a predetermined amount. That is, in a conventionally known revolving type winding machine that revolves to change the positions of both mandrels when fully wound, the mandrel (1a) on the winding position side is always in its fixed position as shown in FIG. Roller bale (10 ') and traverse guide (15') which are locked and therefore brought into contact with the mandrel during the growth of the wound layer.
Is generally moved to the outside.

(Problems to be Solved by the Invention) In the conventional revolving type winding machine, the roller bale and the traverse guide are gradually moved outward as the winding diameter of the mandrel is locked and fixed at a fixed position. And a moving device for mutually converting the positions of the mandrel at the winding position and the mandrel at the standby position when the mandrel at the winding position is fully wound, and a roller bale for the mandrel at the winding position. Since it is necessary to move the traverse guide outward, there is a problem that the occupied space becomes large when the winding device is provided in multiple stages.

(Means for Solving the Problems) The present invention eliminates the above-mentioned conventional obstacles, omits the moving device of the roller bale and traverse guide, and makes the mandrel at the winding position movable, and the moving direction thereof is fully wound. The movement of the mandrel with the winding diameter increase at the winding position and the mandrel position conversion movement at the time of full winding are set as one system of the operating device so as to follow the revolution trajectory of the position conversion operation of both mandrels at the time. The purpose is to simplify the structure and reduce the space required for operation, and this is achieved by providing the following structures.

(A) It consists of a plurality of winding machines arranged in a plurality of upper and lower stages for winding the yarns that are fed substantially vertically downward along the yarn guide path. (B) Each winding machine is centered on a horizontal axis. At a target position on the same circumference of the rotating member that rotates, a pair of mandrels are arranged with their axes parallel to the rotating shaft of the rotating member, and the bobbin supported by the mandrel by the rotation of the rotating member, The winding position and the standby position are switched on a substantially horizontal plane including the rotation axis of the rotating member. (C) Outside the revolution locus of the outer periphery of the empty bobbin on the side of the rotating member at the winding position side. The roller bale was placed at the position, (d) The traverse device provided with a traverse guide for traversing the yarn in the length direction of the mandrel above the bobbin facing side of the roller bale was placed on the machine frame, (E) The roller bale is rotatably supported by the tip of the swing member. And that the roller bail is spring-biased in the direction in which the roller bale contacts the side surface of the bobbin on the thread winding position side on the thread winding side, (f) The roller bale revolves around the outer circumference of the empty bobbin. A stopper for restricting the rotation of the swing member is provided so that the roller bale is in a fixed position held by the abutment of the stopper and the swing member so that the swing member is most shaken. A proximity switch is provided at a position close to the moving member, and (h) the roller bale resists the spring urging force due to an increase in contact pressure with an increase in the winding diameter of the bobbin wound on the bobbin on the bobbin winding position side. The proximity switch detects the deviation from the fixed position, and (i) the motor for driving the rotating member causes the rotating member to move stepwise based on the detection signal to set the roller bale. Return to the position, and The bobbin supported on the mandrel at the bobbin winding position, the roller bale deviation detection signal transmitted from the proximity switch causes the bobbin to be wound while gradually moving downward from the bobbin winding position, and when fully wound, By further rotating the rotating member, the full bobbin and the empty bobbin supported by the mandrel at the standby position are transferred.

(Operation) In the present invention, as shown in the embodiment of FIG. 1 and FIG. 2, the pair of mandrels (1a) (1b) includes the rotating member (2).
Of the rotary shaft (2a) is rotatably supported at the winding position A and the standby position B respectively, and the rotating member (2) is rotated by a motor (6) as a driving force to rotate both mandrels. Drive axis (2
Revolve around a).

The yarn Y is wound around the mandrel (1a) while being traversed by the traverse guide (15), and when the contact pressure exceeds the target value due to the increase in the winding diameter, the roller bale (10) is resisted against the biasing force of the spring (11). ) Is pushed slightly outward from the fixed position determined by the contact between the lever (9) and the stopper (12), and in the normal state, the proximity switch (with the roller bale (10) in contact with the mandrel (1a) ( The other end of the lever (9) having a roller bale (10) closely facing the switch (13) is connected to the switch (1).
Since the roller bail (10) is separated from the fixed position (3), the deviation of the roller bale (10) from the fixed position is detected by the switch (13), and the motor (6) is activated by the detection signal to rotate the rotating member (2). Both mandrels (1a) are moved in the revolving direction, and as the mandrel (1a) rotates in the revolving direction, the roller bale (10) returns to the fixed position and the contact pressure reaches the target value. Upon recovery, the lever (9) and proximity switch
When returning to the normal facing relationship, the motor stops, and the mandrel (1a) winds the yarn at the movement stop position. By repeating this operation, both mandrels step forward in the revolving direction, and the mandrel (1a) ), And when the wound layer reaches a predetermined amount, this is detected by the limit switch (16) and the drive circuit of the motor (6) is held by itself and revolved by the rotating member (2). When both mandrels reach the mutual conversion position, another limit switch (17) detects this and stops the motor (6) to start winding operation on the mandrel (1b) at the winding position. Then, the bobbin of the full mandrel (1a) is replaced.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings.

A pair of mandrels (1a) (1b) are connected to the rotation axis (2a) of the rotation member 2 at the symmetrical positions on the same circumference of the disk-shaped rotation member 2 which rotates about the horizontal axis. The mandrels (1a) (1a) (1a) arranged in parallel are rotated by the rotation of the rotating member (2).
The bobbin supported by b) is switched between a winding position (A) and a standby position (B) on a substantially horizontal plane including the rotation axis of the rotating member (2), and each mandrel (1a) ( 1b) is carried by the output shafts of drive motors (3a) and (3b), respectively.

The rotating member (2) is held by a plurality of supporting wheels (5) whose peripheral edges are pivotally supported by a stationary machine frame (4), and the rotating shaft (2a) is driven by, for example, a stepping motor (6). The bobbin on the mandrel (1a) at the bobbin winding position (A) supported by the rotating member (2) is gradually rotated downward by being rotated by the gear transmission mechanism (7). And move in steps (direction shown by arrow in FIG. 1). As a result, each mandrel (1a) (1b) is connected to the drive motor (3
a) Revolution by rotation of the rotating member (2) as well as rotation by (3b).

Machine frame (4) on the mandrel (1a) side at the winding position A
A frame (8) is provided on the roller bail (10), and a lever (9) as a swinging member is pivotally supported by the frame (8) at the middle thereof, and a roller bale (10) rotatably attached to the tip of the lever (9). ) Is exerted on the lever (9) by the force of the spring (11) for contact pressure setting, as is apparent from the arrow shown in FIG. 1, the mandrel (1
The bobbin supported by a) is pressed against the thread winding side surface of the bobbin, and the lever (9) is further provided with a stopper (12) using a screw piece.
To keep the roller bale (10) in a fixed position, and when the roller bale (10) is in the fixed position at the other end of the roller bale (10), the proximity switch (13 ) Is provided.

Further, a known traverse device (14) is fixedly provided on the machine frame (4) on the winding position A side, and the traverse guide (15) is traversed along the longitudinal direction of the mandrel (1a). I chose

As shown in FIG. 1, the yarn Y is fed substantially vertically downward along a yarn guide path, and wound around a bobbin via a traverse guide (15) and a roller bale (10). By doing this,
As known in the art, even if the yarn is cut, it is prevented from being entangled with other winding yarns and being wound into another winding machine.

A full-roll detection limit switch (16) and a mandrel conversion position stop limit switch (17) are provided on the front and back sides of the machine frame (4) at predetermined positions outside the rotation locus of the rotation member (2), and the rotation member is also provided. On the front surface of (2), the operating protrusions (16a) and (16b) for the two mandrels for the full-winding detection limit switch (16) are provided, respectively, and on the back surface for the conversion position stop limit switch (17). Working protrusion (17a)
(17b) is provided.

 FIG. 3 shows an electric circuit for winding operation.

Thus, in the winding operation of the mandrel (1a) on the side of the winding position (A) in the above configuration, the contact pressure increases with the increase of the winding layer until the mandrel is fully wound. ) Is pushed outward against the pressing force preset by the spring (11), the proximity switch (1
3) outputs a roller bale deviation detection signal, and the stepping motor (6) is started and stopped by the signal, the mandrel is stepped in the direction of revolution, and the roller bale (10) is returned to a fixed position to apply contact pressure. The value is corrected to the target value, and after that, the roller bale deviation detection signal transmitted from the proximity switch causes the yarn to be wound while gradually stepping downward from the yarn winding position A to operate at the position where the winding is completed. Protrusion (16
The limit switch (16) is closed by a) and the relay (16 ') shown in Fig. 3 causes the electric circuit for winding the yarn to be held by itself and the stepping motor (6) is continuously operated to revolve both mandrels. , When the full mandrel (1a) reaches the standby position B and the other mandrel (1b) reaches the winding position A, the operating projection (17a) acts on the limit switch (17) to perform stepping. Since the motor is stopped, the yarn Y is wound around the mandrel (1b) at the winding position A, and the winding operation is performed.
The winding bobbin of a) was replaced, and the conversion operation was repeated when the mandrel (1b) was fully wound as described above.

In the above embodiment, the stepping motor (6) is used as a means for revolving the mandrels (1a), (1b) respectively, and the stepping motor (6) is started and stopped by the roller bale deviation detection signal of the proximity switch (13). As described above, the mandrel revolving movement means is not limited to the case where the stepping motor is used, and other known drive motors can be used to perform the same operation.

As described above, in this device, the roller bale (10)
Is rotatably supported on the tip of a lever (9) (oscillating member), and the lever in the direction in which the roller bale (10) contacts the side of the bobbin on the thread winding position side on the thread winding side. (9) is urged by a spring (11), and the lever (9) is received by a stopper (12), so that a roller bale (10)
Is kept at a fixed position, the surface pressure can be stably controlled only by adjusting the biasing force of the spring (11).
The roller bale (10) can be held at a fixed position defined by the stopper (12) regardless of the magnitude of the surface pressure set by the spring (12), and the surface pressure can be easily adjusted.

Moreover, the roller bale (10) is placed outside the revolving locus of the bobbin on the side of the rotating member (2) at the bobbin winding position (A) side, and above the tangent line of the roller bale (10) on the mandrel facing side. The traverse guide is arranged on the
Since the bobbin supported by the mandrel (1a) at the bobbin winding position is progressively moved downward, the bobbin is wound around the bobbin. Therefore, as shown in FIG. The yarn Y supplied to the bobbin can be wound around the bobbin with almost no bending, and the winding angle of the yarn does not become extremely large even if the winding layer advances and the number of winding layers increases (Fig. 1). As is clear from 90
Below °).

Moreover, as shown in FIG. 4, the mandrel (1a) at the winding position A moves in the revolving direction at the time of position conversion as the winding layer increases, and absorbs the increase in the winding diameter. However, while the roller bale (10) and the traverse guide (15) are almost immobile in the fixed position, the conventional one has the mandrel (1a) wound up to full winding as shown in FIG. Since the roller bail (10 ') and the traverse guide (15') are stopped at the position A and are immovable, the roller bail (10 ') and the traverse guide (15') are moved outward as the number of winding layers increases. The occupied space is different as indicated by X and X ', and the conventional one requires the moving space because the yarn feeding portion by the traverse guide (15') is moved outward.

Therefore, when the winding device is formed in multiple stages as shown in FIG. 6, according to the present invention, as shown in FIG. 6, the devices can be installed in an almost vertical vertical relationship. Roller bale (10) and traverse guide (15 ')
In the case of moving the roller in the horizontal direction, there is no choice but to incline the vertical relationship depending on the position of the yarn feeding section as shown in FIG. As shown in FIG. (C), the degree of inclination is further increased, and a conventional installation requires a large installation space as compared with the present invention (A).

(Effect of the Invention) According to the present invention, the roller bale and the traverse guide are fixed at fixed positions during the winding process until full winding, and from the target value of the contact pressure that accompanies the increase of the winding layer due to the winding. Since the mandrel is moved so as to absorb the increase in the movement of the bobbin, the operating space occupied by the mandrel is smaller than that of the conventional one and the bobbin outside the rotation locus of the bobbin on the side of the bobbin winding position. Since the pivot member is pivotally supported at the point and the roller bale at the tip of the pivot member is brought into contact with the side of the bobbin at the bobbin winding position on the winding side by the biasing force of the spring, By slightly shifting the upper and lower revolving type winding machines to the left and right, you can feed the lower revolving type winding machine without being disturbed by the upper revolving type winding machine.
When installed in a multi-stage revolving type winding machine, it takes up less space than the conventional example, and the movement of the mandrel during winding is the same as the revolution direction trajectory of the conversion operation with the standby mandrel when fully wound. Therefore, the movement can be carried out by a single actuator and is simplified.
The proximity switch detects the slight deviation of the roller bale that moves against the spring pressure due to the increase in the contact pressure as the number of winding layers increases. By setting the deviation amount of the roller bale small, the hardness of each unit winding layer can be averaged by making the change of the surface pressure during forming each unit winding layer by the roller bale small, and Since the roller bale is held in a fixed position by the stopper, it is easy to adjust the spring load at the fixed position.

Moreover, the roller bale is set to a fixed value outside the revolving locus of the bobbin on the side of the winding member on the winding position side, and the traverse guide is arranged above the tangent to the bobbin facing side of the roller bale, and Since the bobbin supporting the moving member on the mandrel at the bobbin winding position gradually moves the rotating member downward, the bobbin is wound on the bobbin.
At the beginning of winding, the yarn supplied vertically downward can be wound on the bobbin with almost no bending, and the winding angle of the yarn does not become extremely large even if the winding layer increases and the winding layer increases. And so on.
