Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device for mainly winding a knitted fabric into a roll in a circular knitting machine, and more specifically, it automatically carries out only the rolled full-blank fabric. The present invention relates to a dough winding device having an automatic doffing function.

[0002]

2. Description of the Related Art A winding device for a circular knitting machine has a rotating machine frame connected to a lower portion of a cylinder base cylinder of the circular knitting machine, in which a winding shaft driven and rotated by the rotation of the machine frame is detachably mounted. When the knitted fabric is wound around the take-up shaft in a roll shape and the wound fabric is full, the machine base is stopped and the roll-shaped full fabric is removed together with the take-up shaft, and the fabric is fully rolled outside the machine. The take-up shaft was pulled out from the dough to carry out the full-rolled dough, and an empty take-up shaft was attached to the take-up device to restart the take-up. Conventionally, all of these operations have been performed manually, but an auto doffer has been proposed that automates this process. However, in the case of such an auto doffer, it is necessary to prepare a plurality of take-up shafts in order to smoothly perform the doffing, and to construct a system that circulates the take-up shafts.
And it was not always efficient because it became large-scale.

Therefore, as an alternative to the above, there has been developed a dough winding device for performing automatic doffing without circulating the winding shaft. As such a device, for example, JP-A-62-104948 and JP-A-3-45756 disclose a device for dividing a winding shaft into left and right parts and pulling out to both sides to discharge a full fabric. Also, Japanese Patent Laid-Open No. 1-2662
Japanese Patent Laid-Open No. 54-54 discloses a device in which the left and right winding bodies are composed of a plurality of stages of telescopic fitting cylinders.

Of these, the former one requires a long stroke to pull out the left and right take-up shafts, takes a lot of time for processing, and has a problem that the device becomes large in size. There is a problem in that the device and the operation procedure become complicated when an attempt is made to downsize the drawing mechanism. Further, in the latter, the telescopic fitting cylinder adopted as the winding body for downsizing is inevitable eccentricity at the tip side,
In order to prevent this, it is necessary to secure a large number of overlapping parts of the telescopic fitting cylinder, which does not necessarily lead to downsizing, but rather complicates the device and ensures stability of control operation. It was difficult.

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned problems of the prior art, the present invention is capable of winding dough without a circulating core, and downsizing and simplification of the device, Another object of the present invention is to provide a dough winding device capable of achieving simplification of the operation procedure and improvement of the processing speed when performing automatic doffing.

As shown in FIGS. 3 and 4, the cloth gripping device 3 includes movable brackets 44 arranged on both sides of the winding position.
It is fixed to the hub 34 provided on the tip flange portion 331 of the rotating shaft 33 that is rotatably supported by bearings 441 and 441, and basically forms a hollow cylindrical body. The winding member 31 formed by forming a slit 311 extending in parallel with the axial direction of rotation toward the base end side, and the material F introduced into the hollow space 312 in the cylinder through the slit 311 of the winding member 31. It is composed of a gripping means 32 for gripping the end portion.

The gripping means 32 is inserted into the hollow portion 312 of the winding member 31, and sandwiches the slit 311 with the movable-side gripping member 321 having a partially cylindrical cross section along the inner peripheral surface of the winding member 31. The movable-side gripping member 321 and a fixed-side gripping member 322 fixed to the inner peripheral surface of the winding member 31 on the opposite side are mainly configured. The movable-side gripping member 321 is fixed to the tip of a rotating shaft 35 that is rotatably supported in the hub 34 at a base end portion that is concentric with the winding member 31 and has a circular cross section. It can be rotated. The fixed side gripping member 322 may not be provided, and the dough may be gripped between the outer peripheral surface of the movable side gripping member 321 and the inner peripheral surface of the winding member 31 along the slit 311.
In that case, the curvature of the peripheral surface along the front edge of the movable gripping member 321 is made larger than the pole ratio of the inner peripheral surface of the winding member 31, so that the portion from the portion along the front edge of the movable side gripping member 321 moves toward the center side. The winding member 31 may have a shape gradually approaching the inner peripheral surface of the winding member 31.

A rack 37 meshes with the pinion 36 formed on the rotary shaft 35 of the movable side gripping member 321. As shown in FIG. 5, the rack 37 is bored across the hub 34, and is slidably inserted into a circular hole 341 communicating with the inner empty portion of the hub 34 at an intermediate portion thereof. At, the two end plates 381 and 382 of the sliding member 38 are fitted and fixed.

The sliding member 38 includes the end plates 381 and 3 on both sides.
The sliding shafts 383 and 383, which are respectively inserted into the two circular holes 342 and 342 formed in the hub 34 in parallel with the circular hole 341, are provided between the two 82 and are integrated together. The lower half of 342 and 342 in FIG. 5 is expanded in diameter to form spring holding portions 343 and 343, and springs 384 and 384 are provided between the spring holding portions 343 and 343 and one side end plate 382. Is intervening.

The sliding member 38 and the rack 37 integral with the sliding member 38 are normally urged by the springs 384 and 384, as shown in FIG. 5 and FIG.
1 is close to the hub 34, the other side end plate 382 is separated from the hub 34, and in that state, the movable side gripping member 321
The front edge of the rotating direction is pressed against the fixed-side gripping member 322, and the slit 311 of the winding member 31 is closed by the movable-side gripping member 321. From this state, FIG.
As shown in (a), the side end plate 382 of the sliding member 38 is pressed against the biasing force of the springs 384 and 384 by the plunger 39 by the operation of the air cylinder 40 described later, and the sliding member 38 is moved to the side. When the end plate 382 slides to the position where it abuts on the hub 34, the rotating shaft 35 rotates about 90 ° counterclockwise in the figure via the pinion 36 that meshes with the rack 37 integrated with the sliding member 38. In that state, the movable side gripping member 321
Is separated from the fixed-side gripping member 322 and is retracted from the slit 311 of the winding member 31.
1 is open. Then, after the material edge Fe is introduced into the slit 311 in the open state, the plunger 39 is separated, whereby the sliding member 38 is returned to the original position by the biasing of the springs 384 and 384, and the movable side gripping member. 321 rotates clockwise, and the winding member 31
It is possible to grip the material end Fe between the front edge of the movable side gripping member 321 and the fixed side gripping member 322 while bending the material end Fe along the inner peripheral surface along the slit 311.

The DC brushless motor includes a rotational position detecting means such as a magnet and a Hall element, and a control unit including a transistor switching circuit or a thyristor, which controls the rotational speed and accurately controls the left and right motors 54, 54. The rotation of the rotor can be synchronized, and the position of the rotor can be held if necessary at the time of detecting the origin, which will be described later. still,
A single motor common to the left and right dough gripping devices 3, 3 is used, and its rotation is distributed to the left and right sides via a rotation transmission means such as a line shaft, gears, belts or chains, and mechanically rotated. Although it is possible to obtain synchronization, since the dough gripping devices 3 and 3 slide in the axial direction, it is necessary to use a sliding means such as a spline, which complicates the mechanism. On the other hand, in the above embodiment, the motor 54 is fixed to the movable frame 44, and the mechanism is extremely simple.

Further, as shown in FIG. 3, a rotation origin detecting sensor 56 is provided so as to face the peripheral surface of the collar 57 fixed to the end of the rotary shaft 33 of the dough gripping device 3. The rotation origin detecting sensor 56 uses, for example, a magnetic sensor to detect a detected body 58 such as a permanent magnet provided at the rotation origin on the peripheral surface of the collar 57. Then, at the rotation origin, the slit 311 of the winding member 31 is shown in FIG.
As shown in (b), it is positioned in the upward direction which is the dough introduction direction. The rotation origin detection sensor 56
Detects the rotation of the rotating shaft 33 for each rotation in the normal winding state other than when the origin of the winding member 31 is detected. When the left and right detection signals are deviated, the rotation error of the rotary shaft 33 can be corrected by instantaneously stopping the advancing motor 54. As a result, it is possible to prevent the situation in which the rotation error is accumulated and the winding material F is twisted.

Next, the operation of the dough winding device 1 will be described by taking as an example the process of winding the dough and unloading the wound dough, that is, the automatic doffing process.

The tubular material F knitted on the knitting side is flatly spread by an auxiliary roller 11 and taken up by three material lowering rollers 8, 9, 10. The material lowering rollers 8, 9 and 10 are rotated by the motor 27 shown in FIG. 1 so that the central roller 8 is rotated via the reduction gear train 28 and the rollers 9 and 10 on both sides are rotated by a gear (not shown).
10 rotates in a state of being pressed against the roller 8 to pull down the knitted fabric and apply an appropriate knitting tension. Then, at the start of the operation, when a certain amount of the fabric F is knitted, the operation of the knitting machine is once stopped, and the preparatory work for winding the fabric F by the winding device 1 is manually performed. Perform as follows.

First, the fabric F having passed through the fabric pull-down rollers 8, 9 and 10 is guided by the tension roller 12 so as to be folded and guided to the idle roller 61, and the air cylinder 6 is also provided.
6 to lower the clamp 62,
The cloth F is gripped between the idle roller 61 and the idle roller 61.
On the other hand, the air cylinder 40 is operated, and as shown in FIG. 4A, the plunger 39 pushes up the swinging member 38 and the rack 37 integrated with the swinging member 38 to move the movable-side gripping member 321 of the cloth gripping device 3 counterclockwise. It rotates and the fixed side gripping member 32
2, and the slit 311 is opened.

Next, after the material end Fe hanging from the idle roller 61 is inserted into the material guide member 67 in the hanging position where the piston rod of the air cylinder 68 is extended, the rodless air cylinders 64, 64 are operated to idle. The roller 61 and the cloth guide member 67 are lowered to introduce the cloth tip Fe into the open slit 311 of the winding member 31 of the cloth gripping device 3 (the state shown in FIG. 7A). After completing these preparatory work, the winding device 1 and the knitting machine are automatically operated.

When the winding device 1 starts the automatic operation, first, the piston rod of the air cylinder 40 is retracted and the plunger 39 is separated from the sliding member 38, whereby the spring as shown in FIG. The gripping member 32 is rotated clockwise by about 90 ° by the urging force of 384 and 384, and the cloth F is moved toward the front edge of the gripping member 321 in the rotation direction and the winding member 3.
While bending on the inner peripheral surface along the slit 311 of 1,
The movable side gripping member 321 and the fixed side gripping member 322 are used for gripping.

Then, after releasing the clamp 62, the motor 54 rotates the rotary shaft 33 and the hub 34 together with the pair of left and right winding members 31, 31 for several revolutions to pre-wind (FIG. 7 (b)).
State). At this time, although there is no winding core in the middle part between the left and right winding members 31, 31,
The winding members 31, 31 holding both sides of the cloth F rotate in synchronization, and at both ends of the cloth where the winding members 31, 31 exist, the cloth F is attached to the outer peripheral surface of the winding members 31, 31. By being wound in a cylindrical shape along it, the intermediate portion of the cloth on the extension is also wound in a cylindrical shape, although some distortion is caused. Then, after the pre-winding, the wound cloth F itself becomes a core, and the cloth F is wound on the core.

After that, the idle roller 61 and the clamp 6
When 2 etc. rises and shifts to main winding, tension roller 1
The limit switches 123 and 124 of No. 2 are activated, the detection of the tension between the material pull-down rollers 8, 9 and 10 and the winding portion is started, and the following control is performed so as to wind at a constant tension.

That is, the material lowering rollers 8, 9 and 10 lower the material F with a constant torque, but the winding speed of the material F increases as the winding diameter increases in the winding section. Alternatively, the take-up tension of the cloth F is increased by decreasing the cloth lowering speed by changing the knitting pattern. Then, the tension roller 12 swings to the idle roller side which is the right direction in FIG. 2 against the biasing force of the spring 122, and when the swing arm 121 reaches the limit switch 123, the limit switch 123 operates, A signal for stopping (or decelerating) the motor 54 of the driving means 5 is transmitted to the control device to control the winding tension between the winding portion and the material pulling down rollers 8, 9, 10 to be lowered.

On the other hand, when the motor 54 of the driving means 5 is stopped (or decelerated), or the material lowering speed is increased by changing the knitting pattern, the take-up speed of the material F is lowered by the material lowering rollers 8 ,. When it is lower than the pulling down speed of the fabric F by 9 and 10, the winding tension of the fabric F decreases. Then, the tension roller 12 is prevented from swinging to the left in FIG. 2 by the urging force of the spring 28 to prevent the fabric F from loosening, and the swing arm 121 reaches the limit switch 124.
24 is operated to send a signal to the control device to drive (or speed up) the motor 54 of the drive device 5 to compensate the winding tension between the winding portion and the material lowering rollers 8, 9 and 10. I do.

By these controls, the fabric F is pulled down with a constant torque, and the fabric F is applied to the winding members 31, 31.
Is wound with a constant winding tension (state shown in FIG. 7C). Then, due to the increase in the number of winding layers, the dough is compressed in the radial direction, and as a result, the dough end faces tend to bulge out to both sides, but the dough end face support plates 13 and 13 prevent this and keep the winding width constant. Hold on. In addition, the material edge supporting plate 1
By contacting the end faces of the cloth F, the cloths 3, 13 rotate together with the winding cloth F, and the cloth F is not damaged by friction.

When the take-up cloth is full, the motor 54 is stopped and the take-up of the cloth F is stopped. At this time, if the tension roller 12 is not in the lower position (on the side of the limit switch 124) shown by the solid line in the figure, only the knitting is continued after the winding is stopped for the reason described later, and the fabric F is further supplied. As a result, the tension roller 12 descends and the knitting is stopped by the operation of the limit switch 124 (state shown in FIG. 7D). Then, the knitting machine and the winding device 1 carry out the full fabric Ff after stopping for a few seconds in the following operating procedure.

First, as shown in FIG. 7 (e), the winding device 1
The rotating machine frame 2 rotates at a low speed to detect the revolution origin. The revolution origin is detected by, for example, a sensor (not shown) attached to the rotary joint 22 of the rotary machine frame 2. At the revolution origin, the cutting device 7 side, which is the carry-out side, is located opposite to the track 18 of the unloader 17 for carrying out the material. .

Next, as shown in FIG. 7 (f), the cutting device 7 is provided between the full fabric Ff and the idle roller 61.
The rotating blade 74 is rotated by the motor 75 and the rodless air cylinder 71 is operated, and the rotating blade 74 is moved together with the slider 72 from one end side to the other end side of the rotating machine frame 2 to cut the fabric F. I do. Further, in parallel with this, the unloader 17 advances to the lower side of the full fabric Ff at the winding position.

Next, the fluid pressure swing motor 4 of the sliding device 4
9 operates to swing the swinging arm 47 to the position shown in FIGS. 3 and 4 (a), and slides the material gripping device 3 together with the movable bracket 44 in the axial direction to set the winding member 31 to the full cloth Ff. Pull out from. At this time, the material end Fe is gripped by the gripping means 32 in the winding member 31, but the material end Fe is fixed by the slit 311 and the movable side gripping member 321 and the fixed side gripping member 322 extending in the axial direction. It deviates easily in the axial direction. Then, the cloth for fabric Ff falls on the unloader 17 as shown in FIGS.

Since the dough winding device of the present invention is configured as described above, it has the following effects.

A dough which is made up of a pair of left and right parts which are rotatably opposed to each other on both sides of the winding position so that their shaft centers are aligned with each other. Gripping device, means for sliding the dough gripping device in the axial direction,
Since a drive means for synchronously rotating the pair of dough-holding devices is provided, the dough is wound up without a circulating core, and the fully-rolled dough is automatically taken out, and the cut dough ends are grasped. It is possible to automatically restart the winding, and to save labor and improve productivity. Also, since the dough gripping device grips only both ends of the dough, its overall length can be made sufficiently short relative to the dough width, which allows the sliding stroke when pulling out the dough gripping device from the full cloth. Shortened,
The entire apparatus can be downsized, large power is not required for pulling out, the processing time required for pulling out is short, and the full fabric can be delivered almost instantaneously.

The dough gripping device forms a slit extending from the outer peripheral surface of the short shaft member to the inner space and extending from the distal end to the base end side of the short shaft member in parallel with the rotation axis direction thereof. It consists of a winding member that can introduce the fabric edge into the slit, and a gripping member that grips the fabric edge by contacting and separating from the winding member or a member fixed to it in the slit, so that the fabric can be reliably gripped with a small amount of power. By winding both ends of the dough on the outer circumference of the winding member, the dough itself can be surely wound even in the central portion of the dough without the core, and after winding the dough. Also in the above, the dough gripping device can be easily pulled out from the fully-fabric dough regardless of the winding layer.

The winding member has a hollow cylindrical shape, the slit is formed by cutting out the peripheral wall, and the gripping member is concentric with the winding member rotatable along the inner peripheral surface of the winding member. Has a cylindrical shape in cross section, and abuts on the inner peripheral surface of the winding member to the front edge in the rotation direction of the gripping member whose slit is closed by rotation, and grips the material end between them to fix the movable end. Since the side gripping member is provided, the winding member can be thinned while ensuring the strength of the winding member, and thereby the step between the movable side gripping member outer peripheral surface and the winding member outer peripheral surface with the slit portion closed is formed. It is small and has good winding shape.

A dough end face which is rotatably supported on both sides of the take-up position with the dough gripping device having the same axial center as that of the dough gripping device, and has an opening formed at the center thereof through which the dough-holding part of the dough gripping device can penetrate. Since the support plate is provided, it is possible to support and guide both end surfaces of the dough to be wound by the dough gripping device, and to wind the dough into a good winding shape. The dough gripping device can be reliably deviated from.
