Description

[Detailed Description of the Invention] The present invention relates to a piece winding device in which a plurality of square winding pieces are arranged in series on a shaft, and then a yarn such as thread is continuously wound onto these pieces.

Yarns such as Tegusu are generally sold commercially by being wound around plastic winding pieces.

Therefore, when winding the yarn around the winding square piece, it is necessary to wind the yarn at a fixed length, and considering the commercial value, the winding position of the yarn must be uniform regardless of the amount of yarn wound. It is necessary to

As shown in FIG. 4, the winding square piece 1 is provided with a fitting protrusion 2 for fitting into another adjacent winding square piece 1. By fitting the wire into the wire, a long yarn is continuously wound around a large number of pieces, and the yarn is not separated until the pieces that have finished winding the yarn are sold on the market.

However, since the dimensions of the fitting portion between the winding pieces 1 and 1 vary somewhat due to manufacturing, as shown in FIG.
When many take-up square pieces 1, 1... are attached to the fishing shaft 4 in succession, the depth of engagement will not be constant due to variations in the dimensions of the fitting portion of the take-up pieces 1, Directional mounting results in an undefined pitch.

Therefore, when winding a yarn around a large number of winding square pieces 1 that are pivoted in this way, in conventionally proposed devices, the stopping position of the yarn guide device with respect to the winding square pieces 1 is fixed by intermittent movement. Therefore, the center position of the winding square piece 1 in the direction of the winding axis does not coincide with the center position of the yarn guide device.

As a result, the thread may be wound to one side of the winding corner piece 1, resulting in a poor winding posture, or if the positional deviations described above accumulate and become large, the thread may be wound to a predetermined winding corner piece. There was a problem in that the commercial value of the winding square piece on which the thread was wound was lowered, such as when the thread was wound onto the adjacent winding square piece and the winding piece could not be wound at a fixed length.

Therefore, in conventionally proposed devices, the operator constantly monitors the position of the yarn guide device with respect to the winding square piece, and if the winding position of the yarn wound around the winding square piece becomes bad, the operator manually I was fixing it.

Therefore, each worker had to concentrate on operating one machine.

The present invention was developed as a result of research aimed at automating the correction of the position of the yarn guide device with respect to the winding corner piece, which was manually performed by an operator in conventionally proposed devices.

The important point of this invention is that two sliders (a main slider and a sub-slider) are interlocked and connected via an interval adjustment mechanism, one of the sliders is intermittently moved by a reference pitch by an intermittent feed mechanism, and the other is After roughly determining the positional relationship between the yarn guiding device preferably arranged on the slider of the traverse device and the winding corner piece, the positional relationship between them is detected by a piece position detection sensor, and the detected signal is used for the interval adjustment. Feedback is sent to the mechanism and the other slider is slightly moved by the spacing adjustment mechanism to accurately determine the positional relationship between the traverse device and the winding corner piece.

Next, one embodiment of the present invention will be explained with reference to the drawings.

In FIGS. 1 and 2, a drive shaft 9 driven by a fishing shaft drive motor 8 with a brake is rotatably supported on one of side plates 6 and 7 that are set up at a distance from the pedestal 5. is,
A support shaft 12 is slidably attached to the other side plate 7, and is always biased in the direction of arrow A by a spring 10 and movable in the direction of arrow B by a grip lever 11.

A coupling 13 is provided at the inner end of the drive shaft 9, and a bearing 14 is provided at the inner end of the support shaft 12.

A fishing shaft 4 is connected and supported between the drive shaft 9 and the support shaft 12 configured in this manner so as to rotate in conjunction with the drive shaft 9.

A large number of thread winding pieces 1 are arranged in series on the fishing shaft 4.

The attachment of these yarn winding pieces 1 to the fishing shaft 4 is as follows.
As shown in the figure, a fitting protrusion 2 is provided on one side of the winding square piece 1, and a fitting groove 3 is provided on the other side. Fitting protrusion 2 of adjacent winding square piece 1
A large number of winding square pieces 1 are connected by inserting them.

Therefore, when a large number of winding square pieces 1 are connected in this manner, their pitch P will not be constant due to variations in the dimensions of the fitting protrusion 2 and the fitting groove 3.

In the present invention, even if the pitch P of the winding square piece 1 is not constant, the winding square piece 1 is attached to the center of the traverse device 16 and the winding square piece 1 when winding the yarn 15 such as threads around each winding square piece. The center of the image is automatically matched with the center of the image, and this point will be mainly explained below.

Below the fishing shaft 4 is a slide shaft 17 parallel to it.
17 are arranged, and both ends of these slide shafts 17 and 17 are fixed to the side plates 6 and 7, respectively.

A main slider 18 is attached to the slide shaft 17.17.
and the sub-slider 19 are slidably fitted together.

These sliders 18 and 19 are interlocked and connected via a spacing adjustment mechanism 20.

The interval adjustment mechanism 20 in this embodiment includes the main slider 1
It consists of a fine adjustment motor 21 attached to the motor 8, and a screw shaft 22 extending from the drive shaft thereof and screwed to the sub slider 19.By rotation of the fine adjustment motor 21 in either the left or right direction, the sub slider 19 is rotated. 19 approaches or separates from the main slider 18, and the main slider 18 moves toward the slide shaft 1.
7, the sub slider 19 follows and interlocks with the main slider 18.

Note that the interval adjustment mechanism 20 may be any mechanism that can move one slider closer to or farther away from the other slider.
The invention is not limited to this example.

One of the main sliders 18 and auxiliary sliders 19 connected through the interval adjustment mechanism 20 in this way (
In this embodiment, the main slider 18) is intermittently fed by an S pitch of 1 minute by an intermittent feed mechanism 23 provided along the direction of movement of the main slider 18).

This intermittent feed mechanism 23 will be explained with reference to FIG.
- This claw 24 is pivotally mounted so as to swing in the direction B.
It is attached so that it abuts against the stopper 25 and does not swing in the direction A from the hanging position.

A large number of cams 27 fixed to the frame feed cam shaft 26 are located at positions facing the tips of the claws 24.

The frame feed cam shaft 26 is disposed parallel to the slide shaft 17, and one end thereof is supported by a drive portion of a frame feed motor 28 with a brake fixed to the side plate 7 so as to be interlocked therewith. The other end of the shaft 26 is rotatably supported by the side plate 6.

The cam 27 fixed to the frame feed cam shaft 26 is
The winding square pieces 1 connected to the fishing shaft 4 are arranged at intervals corresponding to the theoretical pitch P, and furthermore, the tips of the pawls 24 are attached to these cams 27 in the direction of the arrow. A cutout groove 29 is formed that can be passed through in the B direction.

The position of this notch groove 29 has a different phase depending on each cam 27, and when the cams 27... rotate in the direction of arrow C, they move from the cam 27 in the direction of arrow A to the cam 27 in the direction of arrow B. Accordingly, the notch grooves 29 are arranged in order so as to be in positions facing the tips of the claws 24.

Further, a cam disk 31 is attached to the frame speed remoter 28 side of the frame feed camshaft 26 to turn a limit switch 30 on and off.

This cam disc 31 is in contact with the claw 24 of the cam 2.
When the cutout groove 29 of No. 7 rotates to a position facing the pawl 24, the limit switch 30 is activated to stop the frame feed motor 28.

On the other hand, one end of a wire 32 is fixed to the mold slider 18, and the other end is extended in the direction of arrow B, allowing a weight 34 to hang down via a weight pulley 33 attached to the side plate 7.

Therefore, the main slider 18 is always urged in the direction of arrow B by the weight 34.

With the intermittent feeding mechanism 23 configured in this way, the main slider 18 and the sub-slider 19 that follows it are moved in the direction of arrow B by the theoretical pitch P of the winding angle pieces 1 connected to the fishing shaft 4. It is sent intermittently.

Note that the intermittent feeding mechanism 23 is not limited to this embodiment, as long as it can move and stop the slider intermittently at desired pitches.

On the other hand, a traverse device 16, which is a yarn guide device, and a piece position detection sensor 35 are arranged on the sub-slider 19.

The yarn guide device may be a guide that guides the yarn at a fixed position, but is preferably a traverse device 16.

This traverse device 16 has the feature of uniformly winding the yarn 15 pulled out from the yarn drum 36 via the guide 37, pulley 38, and tension device 39 around the winding square piece 1.

The traverse device 16 in this embodiment includes a traverse guide 41 that traverses the yarn by swinging in the direction of arrow A-B with the reciprocating rotation of a fulcrum shaft 40 rotatably supported by the sub-slider 19; a lever 42 extending horizontally from the fulcrum shaft 40;
a traverse cam 44 rotated by a traverse motor 43 and a swinging mechanism that swings the spring 45;
A fixed guide 46 erected from the sub-slider 19 and a solenoid 47 that swings the traverse guide 41 toward the next winding piece 1 (in the direction of arrow B) to pass the yarn to the winding corner piece 1. It is composed of.

The solenoid 47 that causes the thread to pass to the winding square piece 1 is used to ensure that the thread passes to the next winding corner piece 1 when the thread 15 is stiff. This is not necessarily necessary if you have weak backs.

Next, a piece position detection sensor 35 provided on the sub slider 19
To explain, this sensor detects that when the main slider 18 is intermittently moved by the theoretical pitch P in the direction of the arrow B by the intermittent feed mechanism 23, the position of the traverse device 16 on the sub-slider 19 that follows it will change from now on to the yarn thread. This is a sensor that detects whether the winding angle piece matches the winding piece to be wound.

That is, this piece position detection sensor 35 detects the winding square piece 1.
detects the position of the spacer, and if the position is deviated, the signal is fed back to the fine adjustment motor 21 of the interval adjustment mechanism 20.

The fine adjustment motor 21 then finely moves the sub slider 19 with respect to the main slider 18 to make the traverse device 16
The position of the winding corner piece 1 is made to coincide with the position of the winding corner piece 1.

The piece position detection sensor 35 used for this detection is preferably a non-contact sensor so as not to damage the winding square piece 1 or the yarn wound thereon.

On the other hand, the drive shaft 9 that drives the fishing shaft 4 is provided with a yarn constant length winding detection device 48 for detecting the yarn winding length of the winding square piece 1 based on the number of rotations.

This yarn constant length winding detection device 48 includes a notch disk 49 for a counting sensor attached to the drive shaft 9, and a magnetic sensor 50 that detects the notch in this disk and checks the rotation speed of the drive shaft 9. and a counter 51 which counts the number of revolutions of the drive shaft 9 in response to the signal from the magnet sensor 50, and when it reaches a predetermined number of revolutions, outputs a signal to operate the frame speed remoter 28 and returns to zero. ing.

As shown in FIG. 1, limit switches 52 and 53 for detecting the start and end of winding are provided at each stroke end of the main slider 18 and the sub slider 19 in the direction of arrow AB.

Now, in order to automatically wind a yarn to a fixed length on the winding square piece 1, first, the count value of the counter 51 is set to a predetermined number.

Then, the fishing shaft 4 equipped with the winding square piece 1 is set between the drive shaft 9 and the support shaft 12.

Next, the yarn 15 is transferred from the yarn drum 36 to the guide 37 and to the pulley 3.
8. Pass the thread 15 through the fixed guide 46 of the traverse device 16 via the tension device 39, and after passing it further through the traverse guide 41, lock the tip of the thread 15 to the winding square piece 1.

When the fishing shaft drive motor 8 is rotated, the line 15 is first wound around the first winding corner piece 1 (the end in the direction of arrow C in FIG. 3).

At this time, the number of rotations of the winding square piece 1, that is, the number of rotations of the drive shaft 9, is measured using the notch disc 49 for counting sensor and the magnet sensor 5.
It is detected at 0 and this is integrated by the counter 51.

When the thread wound around the winding square piece 1 reaches a certain length, the length is converted into the number of rotations in advance and the counter 51
Therefore, when a predetermined number of rotations is reached and a rotation command signal is issued from the counter 51 to the frame speed remoter 28, the counter 51 returns to zero and counts the number of rotations of the next winding square piece.

The frame speed remoter 28 receiving the signal rotates in the direction of arrow C in FIG. 3.

The cam 2 that the claw 24 of the main slider 18 is in contact with
When the notch groove 29 of No. 7 rotates to a position facing the pawl 24, the limit cam disk 31 turns off the limit switch 30 and stops the frame speed remoter 28.

Therefore, the main slider 18, which is constantly pulled in the direction of the arrow B by the weight 34, passes the notch groove 29 of the cam 27 and moves to the next cam 27 (on the side in the direction of the arrow B).
It comes into contact with and stops.

That is, the main slider 18 and the sub-slider 19 that follows it are intermittently fed in the direction of arrow B by pitch P.

As the sub-slider 19 moves in the direction of arrow B by a pitch of 1 minute, the traverse device 16 also moves, so that the yarn that was wound around the first winding square piece 1 is transferred to the second winding piece. The yarn is passed through the take-up corner piece 1 and wound around this take-up corner piece 1.

In other words, the fishing shaft 4 can continuously wind a fixed length of yarn around the winding square piece 1 without stopping when the main and sub sliders 18 and 19 move.

When the traverse device 16 moves in the direction of arrow B, if the winding center between it and the second winding corner piece 1 is shifted, the piece position detection sensor 35 detects the position of the winding corner piece 1. Then, a signal is sent to the fine adjustment motor 21 to rotate the fine adjustment motor 21 to the left or right, and the screw shaft 22 moves the position of the sub slider 19 relative to the main slider 18 in the direction of arrow A or B. , the winding center of the traverse device 16, which moves slightly at the same time, is automatically aligned with the second winding corner piece 1.

As a result, even if the mounting pitch of the winding square pieces 1 on the fishing shaft 4 is different from the theoretical pitch P, it is possible to uniformly wind a fixed length of thread onto each winding square piece 1. .

In this way, the main slider 18 and the sub slider 19 are intermittently moved in the direction of arrow B while winding a fixed length of yarn around each winding piece 1, and when the winding on each winding square piece 1 is completed,
Limit switch 53 is activated and counter 51 and all motors are stopped.

Note that if you press the emergency stop switch (not shown) while winding the thread around the winding square piece 1, the traverse motor 43
Then, only the fishing shaft drive motor 8 stops, and the counter 51 counts the number of revolutions up to the point when the fishing shaft driving motor 8 stops.Then, the counter 51 stops at the point where the fishing shaft driving motor 8 stops, and then counts the continuation when the winding operation is restarted. Fixed length winding is not affected.

In this embodiment, the case where there is one fishing shaft 4 has been described, but the invention is not limited to this. For example, as shown in FIG.
The main slider 18a, which is intermittently moved by
is slidably attached to the upper slider shafts 17b, 17.
b, a sub slider 19b that follows the main slider 18a;
The sliders 19a are slidably attached, and each sub-slider 19a is
, 19b are respectively provided with the interval adjustment mechanism 2 on the main slider 18a.
It may also be attached via 0a and 20b.

Further, as shown in FIG. 5, a plurality of fishing shafts 4, 4 may be provided in the vertical direction, and a plurality of fishing shafts 4 may be provided in the horizontal direction as shown in FIG.

In this case, the trunk shaft drive motor 8 is placed between the left and right fishing shafts 4, 4.
If the yarn constant length winding detecting device 48a is arranged, there is no need to provide a plurality of them.

As described above, according to the present invention, two sliders are interlocked and connected via an interval adjustment mechanism, one slider is intermittently fed by an intermittent feed mechanism, and the other slider is provided with a yarn guide device, preferably a traversing device. A device is provided, and a piece position detection sensor is provided on the other slider,
The detection signal is fed back to the interval adjustment mechanism.

Therefore, the winding center of the winding piece and the yarn guide device can be automatically and reliably aligned for each piece, which improves the winding posture of the yarn on the winding piece, and the yarn guide device Since the thread does not shift relative to the winding piece, the thread is not wound around any other pieces than the predetermined pieces, and winding of a fixed length can be performed on each piece.

As a result, unlike previously proposed devices, the operator
One person can operate multiple machines without having to work exclusively on one machine.

In addition, if a constant yarn length winding detection device as in the embodiment is provided, the number of turns is detected based on the number of rotations of the winding piece, so that the constant length of the yarn to each winding piece can be determined regardless of the thickness of the yarn. Winding can be performed.

Furthermore, in addition to this, there is also an advantage that even if the rotational speed of the winding piece changes due to a voltage drop or the like, it does not affect the winding of a fixed length, and its effects are significant.
