The bobbin pedestal 42 constituting the bobbin supply part 6 is a semi-cylindrical conveying passage extending longitudinally back and forth by bending a metal plate, and is fixed to the support 40 installed on the main body 1 of the winder 4. The fastening configuration is made through (44), but the semi-cylindrical feed passage is inclined to have a descending slope.

6 and 7, at the lower end of the bobbin pedestal 42, a connecting channel plate 46 for connecting between the bobbin support 42 and the lower bobbin exchanger 48 spaced apart from each other is installed.

The lever bracket 50, which is linked to the rod of the first working cylinder 34a, is axially connected to the fixing bracket 44 of the bobbin pedestal 42, and the front of the downwardly opened “c” shaped lever shaft 50 is thick. An elevated gate 52 is formed in which the wire bar is bent into a "b" shape. A pressing piece 54 is attached to the upper portion of the lever shaft 50, and a bottom support rod 56 across the lower side of the bobbin support 42 is installed on the fixing bracket 44. Further, the retraction locking piece 58 is attached to the side of the bobbin pedestal 42 at a position similar to that of the bottom support rod 56 (preferably a position slightly ahead of the support rod 56).

The first actuating cylinder 34a is telescopically operated by the cylinder drive unit 32 under the control of the control unit 30 and is used for empty bobbin supply.

In the initial state in which the first working cylinder 34a is extended, as shown in FIG. 6, the wire rod of the elevating gate 52 is lowered so that the first-order bobbin B waiting for supply is trapped in the elevating gate 52. At the same time, the rear portion of the second-rank bobbin B, which is inserted behind the first-rank bobbin B, is sandwiched between the tanji rod 56 and the pressing piece 54 to maintain a stable supply standby state.

When the bobbin is supplied, the first actuating cylinder 34a contracts and retracts under the control of the controller 30. Accordingly, as shown in FIG. 7, the lever shaft 50 is turned back slightly to raise the elevating gate 52 to open the passage. At the same time, the pressing piece 54 located above the lever shaft 50 is pushed backward to press the rear portion of the second-order bobbin B.

The second-rank bobbin (B) supported on the bottom support rod 56 is pushed back behind the pressing piece (54) by the interaction between the continuous pressing of the pressing piece 54 and the tapered surface shape of the second-rank bobbin (B). If the first-rank bobbin (B) is still fitted to the second-rank bobbin (B), it will retreat with the second-rank bobbin (B).

The pinching piece 74 is fastened to the upper fixing plate 70 so that the upper and lower heights can be adjusted in consideration of various sizes of the bobbin B, and the bobbin supply part 6 is below the lower opening of the left and right wing pieces 72 with the lower ends bent. A detection sensor 78 is mounted on the lever arm 68 to detect whether the bobbin B discharged from the gas is introduced into the bobbin exchanger 48.

Next, the seal cutting portion 62 will be described in more detail with reference to FIGS. 10, 13, and 14, and the flat casing 70 having one side open is fastened to the distal end of the second arm 66, Inside the casing 80, a cutter 82 which is switched by a predetermined angle (for example, 90 °) by a third working cylinder 34c, which is a rotary cylinder installed in the casing 80, is arranged. The cutter 82 is a tool for cutting the thread of the bobbin bobbin (B) is preferably a heating wire to heat the electricity supply, it can be implemented as a blade.

The cutter 82 is preferably mounted on a swivel 84 axially connected to the third actuating cylinder 34c, which is a rotary cylinder, so that the cutter 82 can be safely stored in the inner chamber of the casing 80 when not in use.

The bobbin exchange operation in the bobbin exchange unit 48 and the thread cutting operation of the seal cutting unit 62 are collectively performed under one shrinkage operation in the second operation cylinder 34b.

When the empty bobbin B discharged from the bobbin supply part 6 freely falls and enters the bobbin exchanger 48 through the connecting channel plate 46, the bobbin exchanger 48 inclined as shown in FIG. The bobbin B is burnt in the fitting space portion provided in cooperation with the wing piece 72 and the upper pinching piece 74 to be in a stationary state. When the empty bobbin B is gripped by the gripper of the bobbin exchanger 48, the controller 30 recognizes this based on a detection signal of the detection sensor 78.

When the actual winding operation in the actual winding unit 8 is completed, as shown in FIG. 9, the full wound bobbin B fitted to the spindle 86 is caused by the contracting operation of the fourth operation cylinder 34d for bobbin removal. It is detached by the tail spindles 88 backward and falls to the full tube 26. At the same time, the second actuating cylinder 34b for conveying bobbins is contracted and the bobbin exchanger 48 holding the empty bobbin B above the winder main body 1 is replaced with the winder main body ( Transfer it correctly to the thread winding part 8 located in the front lower side of 1). That is, as shown in FIG. 9, the empty bobbin B held by the gripper of the bobbin exchanger 48 is accurately positioned between the spindle 86 of the thread winding 8 and the tail spindles 88.

In the state where the new empty bobbin B is located on the two spindle axes, under the control of the control unit 30, the fifth actuating cylinder 34e, which is intended for receiving the full volume bobbin, is operated to move the full pipe 26 to the side. The position movement of the mandrel plate 26 is to secure the working space of the thread collecting base 28.

Then, under the control of the control unit 30, the thread collecting base 28 is moved by the operation of the thread collecting base 28, which is connected to the thread collecting base 28, so that the thread is moved to the empty bobbin B of the spindle shaft. To the initial position to be wound (the bite groove position of the bite portion 86a in FIG. 15), and then the fourth bobbin cylinder B connected to the tail spindles 88 is moved forward to operate the empty bobbin B. The spindle 86 and the tailspin 88 are engaged, and at the same time, the bite portion 86a of the spindle 86 holds the thread placed in the bite groove.

The movement of the thread collecting base 28 by the operation of the sixth operation cylinder 34f for thread collecting ensures that the thread is in the initial position to be wound around the empty bobbin B located on the spindle axis, In B), the winding chamber is placed at a position where the cutter 82 of the thread cutting portion 62 can be cut (see FIG. 9).

Next, under the control of the control unit 30, the cutter 82 is rotated and protruded to the outside of the casing 80 by rotating the rotary cylinder-type third working cylinder 34d for cutting, as shown in FIG. 82) cuts the winding chamber of the full bobbin (B). When the cutter 82 is implemented as a hot wire, the hot wire is sufficiently preheated before the cutter 82 is operated under the control of the controller 30.

The pulley shaft is connected to the motor shaft of the drive motor 38 by a pulley belt to receive rotational power, and the spindle 86 has a groove-shaped bite portion 86a for initially asking a thread to be wound on the bobbin B. Configure the tank to operate.

The tail spindle 88 of the spindle driver 22 presses the rear end of the bobbin B positioned on the spindle shaft to bite or release the fourth actuating cylinder 34d, the detection sensor 89a, and the detection piece 89b for removing the bobbin. By the control of the control unit 30 by the control unit 30 is a structure capable of adjusting the front and rear position movement for the engagement and release of the bobbin portion and the bite portion (86a).

The spindle shaft formed by the spindle 86 and the tail spindles 88 is configured to pivot along the pivot guide hole 94 by the pivot table 92 about the pivot shaft 90. That is, the spindle shaft receives the bobbin B from the bobbin exchanger 48, and at the same time, the winding guide unit for changing the bobbin exchange point and the thread input point for dropping the bobbin bobbin B into the full pipe plate 26 ( It is to make a reciprocating swing between the winding operation points close to the guide drum 96 of 24) to wind the yarn evenly.

The tip of the pivot shaft rod 90 of the spindle drive section 22 and the tip of the rotary shaft 98 of the guide drum 96 of the winding guide section 24 are axially fixed to the front shaft fixing plate 102, and the bobbin B The turning guide hole 94 for guiding the spindle shaft to bite is formed in an arc shape on the winder body front plate 1a.

The guide drum 96 constituting the winding guide 24 is arranged in parallel with the spindle axis as a means for guiding the input point of the supply chamber Y variablely. The guide drum 96 may be rotated by a belt connected to a pulley for rotating the spindle shaft by receiving power from the driving motor (38 of FIG. 3), in which case the rotation ratio of the spindle 86 to the guide drum 96 is 1. The pulley ratio (pulley diameter ratio) can be determined at the time of manufacturing the machine so that the guide drum 96 can rotate from 1 to 12: 1.

In the present invention, the cylindrical surface of the guide drum 96 has a slit-type thread feed guide 100 that can be reciprocated once and around the bobbin B front and back when the drum is rotated once in a closed loop shape. In this case, the inclination angle of the thread transfer guide path 100 is preferably formed to be inclined 30 to 60 ° based on the axis of the guide drum 96. The guide drum 96 is completed by combining two cylindrical halves having a portion to be the slit-shaped thread feed guide 100 in the form of an outer circumference with the rotating shaft rod 98 and coalescing into one cylindrical shape, thereby The guide drum 96 is formed with a slit-type thread feed guide path 100 as shown in FIGS. 19 to 21.

The guide drum 96 as described above may set the rotation ratio of the spindle 86 and the guide drum 96 to 6: 1, for example, if the thread is to be wound three times over the entire length of the spindle 86.

Inside the winder main body 1, as shown in FIG. 18, the pivoting platform 104 for pivoting the spindle shaft of the spindle drive part 22 is axially connected to the rear end of the spindle shaft.

The swing operating table 104 is connected to the seventh operating cylinder 34g for spindle axis swing operation through two link arms 106 and 108, and under the control of the control unit 30, the seventh operating cylinder 34g. The spindle shaft holding the bobbin (B) is turned by the expansion and contraction operation.

That is, the tip of the first link arm 106 in the vertical direction among the first and second link arms 106 and 108 linked to each other is connected to the pivoting platform 104 and the second link arm 108 in the horizontal direction. ) Is configured to be axially connected to the vertical support in the main body 1, and the other end rod of the seventh operation cylinder 34g having one end fixed to the link is connected to the second link arm 108 to rotate the spindle axis.

The second link arm 108 is equipped with a weight 112, the thread is wound around the bobbin (B) mounted on the spindle shaft by the weight of the weight 112, the spindle diameter as the thread bundle diameter gradually increases A tension spring 118, which helps to step back from the guide drum 96 little by little and has a balanced tension in up and down, is connected to the connecting link of the first and second link arms 106 and 108. By pulling upwards from the seventh operation cylinder (34g) for spindle shaft turning operation, the pulling force is increased to the same side to reduce the load load by the weight 112 and the spindle shaft to the bobbin change point. On the contrary, a downward pull is applied to the spindle shaft so that the spindle shaft can be unshakably positioned at the bobbin change point.

In addition, the winder main body 1 has an encoder for detecting the traveling length and the number of round trips of the count belt 114 and the count belt 114 having a weight at one end so as to count the actual winding state in the bobbin B ( 116 is provided. The encoder 116 is mounted on the upper horizontal support, and the other end of the count belt 114 is fixed to the second link arm 108, and one end of the count belt 114 having the weight is overtaken by the encoder 116. It is lowered to form the free end.

15 to 17, reference numeral 120 denotes a buffer pad, 122 denotes an idle roller, Y denotes a yarn supplied from the yarn cone 18, and 124 denotes a break of the yarn Y. Dropper to detect.

The yarn (Y) supplied from the yarn cone (18) placed on the bottom plate of the automatic winder (4) passes through the slit-shaped transfer guide path (100) located below the guide drum (96). ) The inside of the rotating shaft rod (98) is wrapped around the guide drum (96) exits to the actual feed point in the conveying guide 100, and then through the idle roller 122, the spindle 86 and the tail spindle (88) It is wound by the bobbin B which is bitten by and rotates. The thread entry point located below the transfer guideway 100 of the guide drum 96 and the thread entry point located to the side of the transfer guideway 100 of the guide drum 96 transfer the bobbin electric field one round-trip in one revolution. Due to the nature of the furnace 100, the thread is always deviated from each other, so there is no thread woven with each other.

Since the idler roller 122 has a rotary axis parallel to the tapered surface of the bobbin B in the spindle shaft and is arranged in a position where the pivotable bobbin B can be placed (see FIGS. 16 and 17), the spindle While pressing the yarn surface wound on the (86) while rotating the idle (idle) at the same time to attenuate the shaking of the yarn introduced from the guide drum (96).

In winding the thread (Y) to the bobbin (B), initially the spindle axis holding the bobbin (B) is located at the bobbin exchange point, and the tail of the thread cut from the full volume bobbin is the bite portion of the spindle ( While the spindle 86 rotates in the state of being bited by 86a), the thread Y is temporarily wound around the bobbin B (about 3 seconds), after which the fourth operation cylinder 34d for bobbin removal is slightly retracted. To retract the tailspins 88 so that the bite portion 86a of the spindle 86 releases the thread tail and the bobbin B remains in the spindle shaft.

Then, when the spindle 86 is rotated, the thread tail of the thread Y is hidden inside the thread layer wound on the bobbin B to clean the appearance of the drawer chamber, and then the seventh operation cylinder for turning the spindle shaft ( 34g) is used to pivot the spindle shaft holding the bobbin B to the winding operation point (clockwise) so that the bobbin B is rotated in proximity to the guide drum 96. As the guide drum 96 rotates, the thread injection point of the guide drum 96 to the bobbin B in the thread transfer guide path 100 is varied, so that the position at which the thread Y is wound on the rotary bobbin B is also variable. . In other words, the yarn Y is wound evenly over the entire length of the rotary bobbin B. FIG.

For example, when the rotation ratio of the spindle 86 and the guide drum 96 is 6: 1, when the bobbin B is rotated three times by the spindle 86, the guide drum 96 is rotated one half of a turn. The supplied thread (Y) moves in a constant speed position and crosses from the rear end to the front end of the bobbin (B) winding battle field. Therefore, the thread Y at the leading end of the bobbin battlefield is moved to the constant speed position and returns to the trailing edge of the bobbin battlefield.

Repeated transverse motion of the yarn Y as described above is to wind the yarn (Y) uniformly to the rotary bobbin (B), using a stable guide drum 96, but the yarn (Y) guide drum 96 By following the pre-formed thread feed guide 100 and by varying the thread input point, even if the thread winding speed is very fast, there is no mechanical force to increase the thread winding productivity, and the noise of the device is not much during operation.

On the other hand, under the control of the control unit 30, the fifth operation cylinder 34e for the full-length plate is operated to separate the full-length bobbin B contained in the full-length plate 26 in one or two stages to collect the full-volume bobbin (16). It is preferable to drop the bobbin exchange and the thread cutting unit 10 after the bobbin exchange at this point.

In addition, the control unit 30 may recognize that the thread is completely wound on the bobbin B through the encoder (116 in FIGS. 3 and 18) and the spindle rotation speed. When the thread is completely wound on the bobbin B, the driving motor 38 may be used. To stop the rotation of the spindle 86.

Then, zero adjustment, which aligns the actual insertion point position of the guide drum 96 with the initial home position, that is, ultra low speed rotation control of the spindle 86 and the guide drum 96 is performed under the control of the control unit 30. 38), and further, by operating the fifth operation cylinder 34e for receiving the full volume bobbin under the control of the control unit 30, in order to receive the full volume bobbin B held by the mandrel plate 26 on the spindle shaft. The mandrel plate 26 is moved below the spindle axis at the bobbin change point.

As described above, the automatic winder 4 of the present invention is to automatically perform the bin bobbin supply, thread cutting, bobbin exchange and cutting operation, thread collecting operation, discharge operation of the full volume bobbin, and the like.

In the present invention, the bobbin is shown and described as an example of the cone type bobbin, but it is apparent to those skilled in the art that it is applicable to a cap type (Y-shaped) bobbin or other bobbins.
