Description

[Detailed description of the invention] The present invention relates to a skein reeling device.

Regarding this skein reeling device, Japanese Patent Application Publication No. 149952 (1982)
The issue describes a special type of skein winding device in which the wire is wound around opposing holding pins to form multiple loops, and one pin then rotates to twist the loops, thereby forming a skein. is disclosed. The stationary pin is then withdrawn through the disengaging plate, thereby disengaging the formed skein from the pin, and withdrawing the skein from the device. In order to control the length of the hank formed, the longitudinal position of this non-rotating pin, the rear pin, is adjustable, but the hank actually retracts during the twisting operation. It has been found that it is desirable to have a structure in which the rear pin is elastically movable in the direction of the rotating front pin in order to accommodate this.

The amount of contraction when twisting the loop to form a skein varies depending on the gauge of the wire and the length of the skein. As a result, the degree of elasticity with which the rear pin moves toward the front pin may be suitable for a particular gauge or length of skein, but may be inappropriate for a different gauge or length of skein, resulting in twisting. Too much or too little shrinkage of the skein during operation can result in the skein becoming malformed or breaking.

Accordingly, the present invention provides at least a pair of pins facing each other, a mechanism for forming a loop of wire around the pins and winding the wire multiple times, and a mechanism for twisting the multiple wire to form a skein. In the skein reeling device comprising a mechanism for rotating one of the opposing pins, in order to cope with the shortening of the skein during the twisting operation,
The present invention provides an apparatus characterized in that one of the opposing pins is driven and the position of the driven pin is actively adjusted with respect to the direction of the other pin.

The invention is particularly applicable to a device of the type disclosed in JP-A-56-149952, in which the wire passes linearly from a feeding device through a skein device to a coil winding machine. and when the coil winding operation is stopped, the wire passes through a guide eye configured to move in a closed annular track around a pair of pins for multiple windings of the wire. .

In addition, in a double skein reeling device, that is, a skein reeling device that can skein two or more wires at the same time, when moving the rear pins elastically, all the rear pins are configured to move simultaneously. If the skeins to be handled have different characteristics, the rear pins will move at the same time, resulting in some skeins being moved too much, and some skeins may be out of shape. with the disadvantages of

Therefore, the present invention further provides two or more pairs of pins facing each other, a mechanism for winding a wire around each pair of pins to form a loop, and a mechanism for simultaneously rotating one of the pins of each pair to form a loop. In a skein reeling device comprising a mechanism for twisting a skein into a skein, one pin of each pair of pins is driven so as to correspond to the shortening of the skein during the twisting operation. The position of each driven pin is
The present invention provides a keeling device configured to jointly adjust in the direction of the other pin of each pair of pins.

Preferably, the pin that is adjusted during the twisting operation is not the pin that is rotated to twist the formed loop into a skein.

The drive for adjusting the position of the pin may be controlled by a microprocessor that also controls the rotation of the pivot pin.

Hereinafter, the present invention will be explained in more detail with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of a basic skein reeling device substantially the same as that disclosed in Japanese Patent Application Laid-open No. 149952/1983, comprising a rotary holder 1 holding a pin 2. The pin holder 1 has a hollow structure, and the wire to be made into a skein is drawn out through the pin holder 1 to a coil winding machine. The keeling device also includes a non-rotatable rear pin 3 which passes through the keel removal plate 5 and is attached to the pivot plate 4. A wire guide eye 6 is provided on the carrier 7, which guide eye 6 moves in a closed annular track around the pins 2 and 3, so that the wire is wound around the pins into a multi-turn loop. The rotating pin holder 1 then rotates to twist the loop into a skein. Furthermore, a chain drive 8 for driving the wire guide eye 6 is also shown.

Naturally, when the skein is twisted by the rotation of the pin 2 by the pin holder 1, the overall length of the skein is shortened as it is twisted. Conventionally, the structure was such that the rear pin 3 could move in the direction of the corresponding pin 2 against the force of the spring. However, if a significant number of pins are placed on a single plate 4, the amount of shrinkage of the skeins formed can vary greatly, so the plates 4 should be separated by a sufficient distance to accommodate the maximum amount of shrinkage. have to be moved. Therefore, if the skein does not shrink to that extent, operational difficulties and poor shape of the skein may occur.

To overcome this difficulty, according to an embodiment of the invention, it is proposed to actively drive the plate 4 and the pin 3 so that they move in the direction of the pin holder 1.

The mechanism for this purpose is shown in detail in FIGS. 2 and 3.

A release plate 5 and a pin arrangement plate 4 pivoted thereon are loosely mounted on gears 16 and 17 which are supported on fixed racks 18 at a predetermined distance. The gears 16 are all idlers, and the gears 17 are interconnected by a shaft 19. The shaft 19 does not have a driving force, and the pedestal formed by the arrangement plate 4 is easy to use.
It has a function to prevent it from rotating. The driving force is supplied by a motor and a reduction gear unit 11 which are integral with the plate 4 and mounted on the bracket 12. The unit 11 has an output pinion 13 meshing with one of the racks for driving the frame.
have.

During the operation of twisting the skein by rotation of the pin holder 1, the pinion 13 is driven at a suitable speed, so that the pin 3 moves appropriately in the direction of the pin 2.
When the plate 4 is rotated by the action of a solenoid (not shown), and the pin 3 is thereby pulled out from the removal plate 5, and the skein is removed from the pin 3, the motor unit is driven in the opposite direction, and the motor unit is driven in the opposite direction. The stand then returns to its normal starting position.

Preferably, the starting position is adjusted by a separate control mechanism of the motor unit 11, so that the length of the skeins formed can be selected as required.

The amount of movement of the rear pin toward the front pin varies depending on the gauge of the wire being skeined and the length of the skein. The extent of this variation may be conveniently obtained by using a programmable microprocessor controlled unit that allows easy selection of the necessary parameters for a particular gauge wire or skein length.

Since the skein winding device is usually used in conjunction with a plurality of coil winding machines, the operation of the drive unit, that is, the chain drive device 8, the rotation drive device of the pin holder 1, and the motor unit 11 is controlled by the coil winding device. A microprocessor may also be used to control the operation of the winding machine. For example, the microprocessor activates the chain drive 8 after winding the coil an appropriate number of times and adjusts the chain drive so as to form the required number of loops between pins 2 and 3. It may be programmed to rotate. The chain drive then returns the wire guide eye 6 to the rest position and then rotates the pin holder 1 a predetermined number of times as recorded in the counter. During this time, the microprocessor acts on the motor and gear unit 11 to drive the pinion 13 at a predetermined speed or movement pattern. When the pin holder 1 completes the required number of rotations, the solenoid acts to swing the plate 4 and pull out the pin 3 from the removal plate 5, thereby removing the skein. The cradle formed by plate 4 then returns to the starting position and is ready for the next coil winding operation.

FIG. 4 shows another embodiment of the pin drive mechanism. The pedestal 20 is supported on both sides by linear bearings 21 that move on rods 22 held by supports 25. The linear bearing 21 is moved along the rod 22 by means of a toothed belt 23. One belt is driven by a motor 24 via a belt 26, and at the same time the driving force is transmitted to the other belt via a shaft 27 and a pulley 28. Although not shown, the pedestal 20 includes a rear pin and a removal plate as shown in FIGS. 2 and 3. The linear bearing 21 supports the pedestal against rotation, while the toothed belt is positively connected to the linear bearing so that it can be driven reliably without slipping.

In FIG. 5a, the pin 29 is held in a bearing 31 to compensate for contraction of the skein during the twisting operation;
A rear pin is shown configured to be pivotable about an axis 30. The front pin is located in the direction of arrow A,
It can be rotated to twist the skein. In a known version of this mechanism, the pin is biased by a spring in the direction of arrow B. When the skein is twisted, pin 3
1 moves around the axis of the shaft 30 against the spring by arrow A
Turn in the direction of. Immediately after passing through the vertical position shown in FIG. 5b, the skein is released from the pins, so that there is no need for an active release action as seen in the previously described mechanisms. However, with this spring-biased mechanism, the skein may become detached before the required number of twisting turns have been made; in fact, the force applied when winding the wire around the pin may There is also a risk that it may rotate.
According to the invention, a mechanism is provided for actively rotating such a pin in the direction of arrow A, preferably in two stages. The first step is to gradually rotate the pin towards the vertical position shown in Figure 5b during the twisting operation to form the skein;
The second step is to rotate the pin beyond the vertical position so that the skein is removed from the pin.

Various other embodiments may be suggested by those skilled in the art, but all such embodiments are within the scope of the present invention.
