Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement of a traverse separation control device for a non-contact type winder that separates the traverse device in accordance with the increase in the winding diameter.

When winding multifilament yarn on a winding machine, the load torque applied to the cradle is balanced between the weight of the winding yarn and the spring or weight to maintain a constant contact pressure between the winding drum and the drive drum. When a so-called surface drive winding method is used in which the yarn is wound on a winding drum, the multifilament yarn has a flat cross section.

In particular, when glass fibers spun from a spinning machine are subjected to focused oiling, for example, and immediately thereafter wound using a surface-driven winding system, the flattened glass fibers tend to become fluffy and their strength decreases. When winding multifilament yarn, a method is generally adopted in which the winding drum (spindle collet) is directly driven and no contact pressure is applied to the winding yarn, since this has a negative effect on the next yarn twisting process.

By the way, the direct drive method requires a means to gradually reduce the rotational speed of the spindle collet in response to the gradually increasing winding diameter, and in addition, in order to maintain the winding width accurately and prevent winding of the end face, the thread conductor is It is necessary to traverse the yarn as close to the winding surface as possible, and this is an essential condition especially when winding the winding end surface into a skew end.

As a means to satisfy the latter condition, the traverse device is separated from the winding surface in response to an increase in the winding diameter, thereby maintaining the thread conductor at the same relative position as the winding start position close to the winding surface. A traverse take-off control device for a winder has been used in the past.

FIG. 1 is a perspective view showing the configuration of the main parts of the -fl. Based on this diagram, a conventional traverse departure control system will first be explained.

Spindle collet 1 that winds multifilament yarn 0
is controlled via a speed control mechanism (not shown) so that the peripheral speed at the winding diameter, that is, the yarn feeding speed, is maintained constant. It is rotationally driven by a variable speed motor 2.

The traverse device 3 is disposed parallel to the spindle collet 1, and rotates a cam built into it (the drive system is not shown) to cause the yarn conductor 4 to reciprocate through a slider and take up one winding. It traverses thread 0, and arm 5
The spindle collet 1 is mounted on the collet 1 and is rotated about a shaft supported by a bearing 6 as a rotation axis, so as to be separated from the spindle collet 1 rotating at a fixed position.

A sector gear 7 is fixed to the other end of the rotating shaft of the arm 5, and is meshed with a rank rod 9 which is configured to move left and right through a follower by rotating a cam 80.

10 is a trunnion-type air cylinder whose operating rod is rotatably connected to a pin embedded in the sector gear 7;
Appropriate amount of clockwise torque to sector gear 7.

This eliminates the bank rack between the sector gear I and the rack 9, applies contact pressure to the cam follower against the cam 8, and further reduces the vibration (... It plays a role in suppressing

11 is an electronically controlled motor that controls the takeoff operation and takeoff speed of the traverse device 3 by an in-plane control unit (not shown), and a gear 12 fixed to the shaft end;
Via the gear 13, the reducer 14 and the joint 15 meshing with it, the torque is increased and the camshaft 18, which is supported by bearings 16, 17, is rotated 80 revolutions of the cam, which corresponds to the distance of the traversing device 3 during the winding cycle time. Provides rotation at a speed defined in correlation to angular displacement.

The cam 8 has a displacement curve that defines the distance of the traverse device 3 (since the yarn feeding speed is constant as described above,
Since the increase in the winding layer per unit time decreases as the winding diameter increases, the separation amount per unit time is gradually decreased.
By driving the arm 5 to the left and further rotating the coaxial arm 5 counterclockwise as shown by the arrow through the sector gear 7 meshing with the arm 5 against the clockwise torque applied from the air cylinder 10. Te, traverse device 37f! The spindle collet 1 is gradually spaced apart from the spindle collet 1.

When changing the final winding yarn diameter, the winding cycle time is adjusted by replacing the gears 12 and 13 with replacement gears each having a predetermined number of teeth, and removing the wound yarn from the spindle collet 1. When starting winding again, the motor 11 is quickly rotated in reverse to return the traverse device 3 to the winding starting position.

As can be seen from the above explanation, in the conventional device, each part of the control device is attached to the machine base of the winder.
Since the space it occupies is large and the structure is complicated, it is not only difficult to maintain, but also the wiring between the electronically controlled motor 11 and the control unit (not shown) in the control plane is quite long. During this time, it has the disadvantage that it is affected by electrical noise and troubles occur from time to time.

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional device.It is arranged parallel to the winding drum and has a sector gear that rotates a traverse device equipped with a reciprocating thread conductor via an arm. , and the pinion that meshes with it.
The machine is equipped with a pulse motor that drives it, and is formed by a displacement curve that gradually decreases the separation amount of the winding layer per unit time, and corresponds to the separation amount of the traverse device during the winding cycle time. and a pulse generator having a pinion having the same number of teeth as the pinion meshing with a rank moved by the cam through a follower, the control surface comprising: The present invention relates to a traverse departure control device for a winding machine, characterized in that the pulse motor is rotated in response to a pulse from a winder.

An embodiment of the device according to this invention will be described below with reference to FIG. 2, which shows the configuration of its main parts.

In the figure, the same reference numerals are given to the same components as those of the conventional device shown in FIG. 1, and the explanation thereof will be omitted.

11' is a small electronically controlled motor mounted within the control surface 20, and a gear 12' is fixed to its shaft.

Reference numeral 8' corresponds to the cam 8 in the conventional device, and is a relatively smaller plate cam, which is fixed to one end of a cam shaft 18' which is rotatably supported by a bearing 21.

At the other end of the camshaft 18' is a gear 13 that meshes with the gear 12'.
' is fixed.

9' is a small rank rod, which is not shown in the figure, but is made to be able to slide vertically by a pair of upper and lower guides, and a follower that engages with cam 8' is rotatably attached to the lower end. It is being

Reference numeral 22 designates a pulse generator installed in the control surface 20, which has a gear 23 fixed to its rotating shaft, and teeth identical to the gear 23 which are rotatably supported by a bearing 24 so as to mesh with the gear 23 and the rack 9'. The vertical linear movement of the rank 9' through the follower due to the rotation of the cam 8' is engaged with the rank rod 9' through a number of intermediate gears 25. It is now being transformed and transmitted.

Reference numeral 26 denotes a pulse motor attached to the machine base, and is connected via a joint to a reduction gear 2T having the same reduction ratio as the reduction gear 14 in the conventional device.

A gear 28 is fixed to the output shaft of the reducer 27, and a gear 29 has the same number of teeth as the gear 28, which is fixed to a shaft 31 that is rotatably supported by a bearing 30.

A pinion 34 having the same number of teeth as the gear 25 that meshes with and rotates the sector gear T that is the same as that of the conventional device is fixed to a shaft 33 that is rotatably supported by a bearing 32.

The reason why the gears 25, 23 and 28, 29 have the same number of teeth meshing with each other is to make the rotation direction different from that of the conventional device.

35 is an electromagnetic clutch that connects the shaft 31 and the shaft 33.

The pulse generator 22 in the control surface 20 and the pulse motor 26 on the machine base are connected via an amplifier 36 by electrical wiring.

Reference numeral 10' denotes a trunnion type air cylinder, which is designed to apply an appropriate amount of clockwise torque to the sector gear 7 as in the conventional device, and when the electromagnetic clutch 35 is connected, the sector gear 7 and It serves to eliminate bank racks between the pinion 34 and gears 28 and 29, and also to suppress any vibrations that occur when the traverse device 3 moves away.

When the electromagnetic clutch 35 is disconnected, the traverse device 3 can be rotated independently of the pulse motor 26.

Next, the operation of this device will be explained.

When the electronically controlled motor 11' rotates at a predetermined rotational speed as described above, the plate cam 8' is rotated by the rotated cam 8' via the gears 12' and 13'.

Because the rank rod 9' is attached to its lower end due to its own weight, the follower is always in contact with the cam 8'. A predetermined lift corresponding to the rotational angular displacement is given to the rank rod 9' as its linear movement.

This linear motion is converted into rotational motion via the gear 25 meshing with the rank 9' and the gear 23 meshing with it, and is transmitted to the pulse generator 22, which is driven to rotate and generates a pulse corresponding to the lift.

This pulse is amplified by an amplifier 36 and input to a pulse motor 26 attached to the machine base to rotate it.

The rotation is caused by the reduction gear 27. Torque is increased and transmitted to the shaft 31 through the gears 28 and 29, and further transmitted to the shaft 33 through the electromagnetic clutch 35, driving the pinion 34 to rotate clockwise, and then through the sector gear 7 that meshes with the pinion 34 to rotate the pinion 34 clockwise. By rotating the upper arm 5 in the counterclockwise direction shown by the arrow against the clockwise torque applied from the air cylinder 10/, the traverse device 3 is gradually moved 111% from the spindle collet 1.

In this way, the traverse device 3 is separated in response to an increase in the winding diameter of the spindle collet 1, and the thread conductor 4 can always be held at the same relative position as the winding start position close to the winding surface.

In this case, the electronically controlled motor 11' and its control unit (not shown) are both housed in the control surface 20, and there is no risk of disturbance due to electrical noise between fairly long wires as in conventional devices. This allows the traverse device 3 to reliably perform the departure operation as set.

In addition, when adjusting the winding cycle time when changing the final winding yarn diameter, a small gear 12' in the control surface 20 is used.
, 13' can be replaced with replacement gears each having a predetermined number of teeth, and this operation can be performed easily and quickly compared to replacing fairly large gears on the machine base in conventional devices.

Remove the wound thread from the spindle collet 1,
To start winding again, after the electromagnetic clutch 35 is connected, the fan gear 7 is moved by the air cylinder 10'.
What is necessary is to rotate clockwise to return the traverse and traverse device 3 to the winding start position.

As is clear from the above explanation, the traverse departure control device for the winding machine according to this invention has two parts, one attached to one machine and one attached to the control box, compared to conventional devices. Since the controller is divided into two parts, it requires less space on the machine base of the control device, has a simple configuration, and is easy to maintain. By housing the control box in the control box, the influence of electrical system noise can be removed, and troubles can be prevented from occurring.

In addition, operations such as changing the final winding diameter can be performed easily and quickly, which greatly contributes to improving the efficiency of the winding work.
