The present invention is rotatably installed on the other side of the base, while the winding wire is wound around the wire rod for which the coating process is not performed, and the wire wound on the winding drum is aligned with the winding drum rotatably installed on the upper side of the base. The present invention relates to a wire rewinding device for rewinding, in particular, in a state in which the wire rewound in a uniformly aligned state in the process of coating an insulating material on the outer diameter of the wire and the wire for wires used as the conductor. By supplying, the defective rate of the wire can be minimized, and if a defect such as an unnecessary protrusion protrudes into the outer diameter of the wire rod in the process of rewinding to align the wire rod, it is immediately detected and at this time, the tension is maintained Quickly search for the location of the defective wire in the state to solve the problem of the location As such, it provides a material of the wire take-up device which makes it possible to improve the reliability of the wire.

In general, the electric wire is formed by coating an insulating layer on the surface of a metal wire made of copper or the like, and the apparatus for manufacturing such electric wire includes a feed roll to which a metal wire is supplied and a winding roll to which the metal wire is wound. And a coating apparatus provided on the conveying path of the metal wires conveyed by the conveying apparatus to coat the insulating layer on the surface of the metal wire, and a cooling tank in which a cooling liquid for curing the insulating layer is stored. The configuration is complicated, such as a refrigerant cycle or a cooling water circulation device for maintaining the temperature of the cooling liquid at an appropriate level.

By this apparatus, the metal wire (hereinafter referred to as wire) is coated with an insulating layer on the surface thereof, and then cooled by water in a cooling tank, where the wire wound on the supply roll is 1 in the process of producing the first wire. It refers to the state of being wound up by the rewinding drum in the rewinding process while being wound up by the winding drum.

That is, the wire rod wound on the supply roll for covering the wire, if the unnecessary wire protrudes due to the outer diameter of the wire rod, because the stable insulation is not made by the protruding wire at the time of coating, the defective rate increases, and also the winding on the feed roll If the wire rod is not wound uniformly, it is essential to maintain it in the coating process by the unaligned winding method, even though the wire rod fed to the coating device should be supplied with the minimum speed and uniform tension and movement. Since the variable must be generated in the element that should be, the core of the wire is not located in the center, and a problem occurs such that it is biased to one side, so that the failure rate is increased because stable insulation is not made.

Therefore, in order to satisfy the essential requirements required in the coating process, the worker first removes the wire protruding to the outer diameter of the wire rod in the rewinding process, and also prioritizes the alignment of the wire rod during the rewinding so that it can be uniformly aligned. Has been implemented.

However, in the conventional rewinding device, the winding drum in which the wire rod has been wound since the wire rod production was configured such that the rewinding drum in which the wire rod was aligned as the wire rod was unwound as the wire rod was released according to the rotation of the DC motor. As the wire rod is wound around the rewinding drum, the wire rod is stretched, so the thickness of the wire rod is not uniform.

In addition, since the rewinding of the wire rod is made at a constant speed, when the defective position of the wire rod is sensed, and the rewinding drum is stopped, the winding drum is rotated at a constant speed by inertia. The wire rods unwinded from the winding drum in the stationary state are loosened so that the tension is alleviated. As a result, problems such as entanglement with each other, interference with the rewinding equipment, or disconnection occur.

In order to solve this problem, the improved rewinding device has introduced a brake device for stopping the winding drum and the rewinding drum at the same time. However, even when the equipment is stopped at the same time, problems such as disconnection and relaxation of tension are not solved. I can't do it.

In particular, in the case of rewinding, the rewinding drum in which the wire is wound increases as the length of the wound wire increases with time, and the speed of pulling the wire gradually increases at the same rotational speed, thereby increasing the linear velocity. In order to maintain a constant tension of the wire wound in response to this can not only be very long, the speed of the rewinding drum is gradually reduced, thereby increasing the time required for the rewinding process, thereby reducing productivity. Has the problem.

The present invention devised to solve the above problems, while maintaining the re-winding speed at a high re-winding process to enable the wire rod to maintain a constant tension, due to the failure of the wire rod arbitrary stop and restart operation is made Even though the tension is maintained, the defects of the wire rod can be exposed to the worker, and the problem of disconnection and non-uniform thickness of the wire which occurs during rewinding can be solved. The purpose is to make it possible to improve productivity by making it happen quickly.

Hereinafter, the configuration and operation of the present invention will be described with reference to FIGS. 1 to 5.

In the rewinding apparatus of the wire rod 102 according to the present invention, the main body 109 is standing up and installed in the center of the base 101, and the rewinding drum 104 for rewinding the wire rod 102 on one side of the main body 109. ) Is installed to be rotated by receiving the power of the second alternating current motor 108 installed below the main body 109 from the belt 105 or the chain 106 to the rotation shaft.

At the other end of the main body 109, the winding drum 103, on which the wire rod 102 to be wound by the rewinding drum 104, is wound, belts the power of the first alternating-current motor 107 installed below the main body 109. It is installed to be rotated by being transmitted from the 105 or the chain 106 to the rotating shaft.

Here, the winding drum 103 and the rewinding drum 104 is provided with a hydraulic cylinder so that the end of the rotary shaft 104a can be reciprocated before and after, as shown in Figure 1 and 2, the weight chain 106 The lift may also be provided so that the winding drum 103 and the rewinding drum 104 can be mounted at the end of the rotational shaft 104a. This technical configuration is generally used in a mechanical mechanism for manipulating most of the weight body. Since it is a well-known technology, the present invention does not limit this, and hereinafter, the description of the detailed configuration and structure will be omitted.

Meanwhile, first and second guide grooves 111a0 and 110a are formed on upper surfaces of both sides of the main body 109 so that the wire rod 102 rewound from the winding drum 103 to the rewinding drum 104 may be guided. The two guide rollers 110 and 111 are installed to allow self-rotation, and at this time, the guide wires 102 to be guided can be stably and uniformly aligned to the rewinding drum 104 only by maintaining a constant tension. Figure 103 shows the tensioning means of the wire rod for maintaining the constant tension of the wire rod 102, which is conveyed while the 103 and the rewinding drum 104 is rotated by the rotation of the first and second alternating motors (107, 108). A description with reference to 2 and 3 as follows.

That is, the upper and lower sprockets 113 and 114 are formed on the upper and lower walls of the interior part 109a formed to be recessed from the front side of the main body 109 as shown in FIGS. 1, 2, and 3. Installation is spaced apart from the rotatable state, and connects the upper and lower sprockets 113 and 114 to the chain 106.

In addition, the pair of first guide rods 116 is fixed on the wall surface of the adjacent interior portion 109a so that the upper and lower ends thereof are fixed by the fixing bracket 115 so that the pair of first guide rods 116 can stand upright in parallel with the chain 106. The first fixed shaft end to which the fixed roller 117 is rotatably coupled to the vertical upper portion of the guide rod 116 is fixed, and the first guide tube 118 is inserted into the pair of guide rods. The first guide pipe 118 is connected to the transfer bracket 120, the rotatable turning roller 121 is installed on the second fixed shaft end fixed to the transfer bracket 120.

In addition, the other side of the first guide pipe 118 of the transfer bracket 120, the chain 106, the transfer bracket 120, the first guide tube 118 is coupled, the transfer bracket 120 and the first guide tube When the 118 moves up and down along the first guide rod 116, the chain 106 moves up and down together, thereby raising and lowering the chain 106 to raise and lower the sprocket 1130 (114). Allow this to rotate.

Here, the fixed roller 117 and the turning roller 121, a plurality of guide grooves (117a) (121a) formed in a groove shape in the circumferential direction at a predetermined interval as shown in Figure 3, the fixed roller The wire rod 102 passing through the first guide roller 110 is fixed roller 117 by forming one more guide groove 117a than the guide groove 121a of the turning roller 121. After being guided to the guide groove 117a of the upper fixed roller 117 via the guide groove 117a of the turning roller 121 and the guide groove 121a of the turning roller 121 to be guided to the second guide roller 111. To be able.

That is, as described above, when the wire rod 102 passing through the fixed roller 117 and the turning roller 121 can be repeated a plurality of times, the guide groove 117a of the fixed roller 117 is the turning roller 121. It is set to be one more than the number of guide grooves 121a).

In addition, the interlocking gear 122 is disposed on the rotation shaft of the lower sprocket 114 to accompany the rotation of the lower sprocket 114 so that the interlocking gear 122 rotates, and the internal part is engaged with the interlocking gear 122. (109a) A deceleration for installing the resistance indicating gear 123 rotatably on the wall, preferably reducing the rotational speed of the interlocking gear 122 at a constant rate between the interlocking gear 122 and the resistance indicating gear 123. It is preferable to install the gear 122a so that the radius of the resistance indicating gear 123 rotates by the lifting and lowering operation of the chain 106 does not exceed 360 °.

Accordingly, the length of the wire rod 102 rewound in the rewinding drum 104 and the wire rod 102 unwinding from the winding drum 103 by the difference in rotational speeds of the first and second alternating motors 107 and 108. When the tension of the wire rod 102 is relaxed or tensioned due to the difference in the length of the turning roller 121, the turning roller 121 moves up and down along the first guide rod 116, and at this time, the chain 106 As the rising and falling of the lower sprocket 114 and the resistance indicating gear 123 is connected to the rotation or rotation operation, the resistance value of the variable resistance is changed by the resistance indicating gear 123, and at this time, The resistance value is compared in the comparison unit by the tension control unit, and at this time, the first and second alternating motors ( 107) It is possible to PID control the speed of 108.

The PID control method will be described in detail later in the description of the operation of the rewinding apparatus.

Here, when the fixing piece 119 of the transfer bracket 120 is located in the middle between the upper and lower sprockets 113 and 114, this position is set as the reference position, and at this time, the resistance indicating gear 123 The resistance value of the variable resistor is set to '0'. When the transfer bracket 120 is moved up and down at this reference position, the resistance value of the variable resistor is increased to '-' by an inverter connected to the resistance indicating gear 123. Or decrease, and when the transfer bracket 120 descends from the reference position, the inverter increases or decreases the resistance value of the variable resistor to a '+' value, thereby increasing the resistance value by increasing the '+' and '-' values. It is desirable to be able to selectively control the speed of the first and second alternating motors 107 and 108.

On the other hand, if the wire is protruded to the outer diameter of the wire rod 102 is guided to any one of the first and second guide rollers (110, 111), this portion is a defective position of the wire rod 102, so detecting this defective position And, the protruding wire is to be removed by the operator, bar defective wire detection means for detecting the position of the defective wire of the wire rod 102 is wound during the re-winding process, as shown in Figure 4 the main body 109 The fixing plate 125 having the detection groove 125a is fixed to the support bracket 124 fixed to the wall of the built-in part 109a, and the '+' terminal is connected to the detection plate 125. At least the main body 109, the fixed roller 117, the turning roller 121, the first, so that the wire rod 102 passing through the detection groove 125a of the detection plate 125 can be connected to the '-' terminal One of the second guide rollers 110 and 111 is connected to the '-' terminal of the wire rod 102 passing through the detection groove 125a of the detection plate 125 Contact with the amount of wire occurs points (wire 102. The wire protrudes) is detected groove (125a) make the signal occurs, and allows this signal is transmitted to the operation control.

Here, since the main body 109 is connected to the '-' terminal, the support plate 124 and the detection plate 125 are preferably insulated from the detection plate 125 coupled to the support bracket 124 as an insulator. .

Meanwhile, when the wire rod 102 guided to the second guide roller 111 is rewound in the rewinding drum 104, the wire rod 102 is wound while being constantly in close contact with one end from the other end, and after reaching the other end, Bars must be re-wound while being uniformly and uniformly inclined toward the end, and the alignment means of the wire rod for this purpose includes a base 101 between one side of the main body 109 and the rewinding drum 104 as shown in FIG. 5. The upright bracket 126 is erected and spaced apart from the front and rear direction, and a second guide rod 127 is inserted into the upper portion to connect the pair of upright brackets 126 from the inside.

The second guide rod 127 is inserted into the second guide tube 128, and the connecting plate 128a is coupled to the bottom of the second guide rod 127, and the lower portion of the second guide rod 127 is disposed below the connecting plate 128a. The transfer body 130 is fastened to the lead screw 129 coupled to the self-rotating inside the upright bracket 126 located in the coupling, and the power of the third alternating motor is transmitted to the end of the lead screw 129. To be possible.

Therefore, the conveying body 130 reciprocates along the thread of the lead screw 129 according to the rotation direction of the lead screw 129, but the second guide pipe 128 on the upper portion of the conveying body 130 has a second guide rod ( By being guided along 127, the conveying body 130 can be linearly reciprocated back and forth.

In addition, the detection unit 131 is installed on the lower portion of the conveying body 130 to protrude, and the fixing bar 135 is installed on the inner side of the upright bracket 126 so as to be positioned below the lead screw 129, The limit sensor 132 is installed on the bar 135 to be spaced apart so that the conveying direction is reversed when the sensing unit 131 of the lower sensing unit 131 is detected by the limit sensor 132.

Therefore, when the sensing unit 131 is sensed by the limit sensor 132, the signal is transmitted to the alignment control unit, and the alignment control unit reverses the rotation direction of the third AC motor so that the transfer body 130 is the limit sensor 132. By not leaving the), the conveying body 130 is able to reciprocate, and the second guide roller 111 by rotatably installing the correction roller 133 to the connecting piece (128b) coupled to the connecting plate (128a) The wire rod 102 via) is guided to the correction roller 133 and then rewound in the rewinding drum 104. At this time, the conveying body 130 continuously reciprocates and thus the winding direction of the wire rod 102 is Since the winding angle is constant, uniform winding is possible.

Here, a pair of prevention rolls 134 are installed on the connecting plate 128a to prevent the wire rod 102 guided by the second guide roller 111 from being biased left and right when guided to the correction roller 133. Then, by being guided to the correction roller 133, it is preferable to be guided similarly when the wire rod 102 wound at a high speed when guided to the correction roller 133 can be prevented from leaving the correction roller 133 Do.

On the other hand, if a defective point of the wire rod 102 re-wound by the defective wire detection means is detected, at the same time the length until the winding drum 103 and the re-winding drum 104 is stopped can be measured. An encoder 112 is installed on the side of the main body 109 adjacent to any one of the first guide roller 110 and the second guide roller 111, and the first guide roller 110 is shown in FIG. Encoder 112 is installed on the main body 109 adjacent to the installation position, and the present invention is not limited thereto because the installation position can be changed in various ways.

When the defective point of the wire rod 102 rewound by the defective wire detecting means is detected, the operation control unit decelerates the first and second alternating-current motors 107 and 108 to a predetermined speed and the wire rod 102. After the feedrate of the motor is decelerated, the brake is controlled to simultaneously stop the winding drum 103 and the rewinding drum 104.

In this case, since the winding outer diameter of the wire rod 102 wound on the winding drum 103 and the rewinding drum 104 is different from each other, when the suspension is stopped at the same time, the tension may be alleviated or tensioned for a moment, but at this time, the tension may be relaxed and tensioned. In accordance with the turning roller 121 is lowered or raised, so even if the wire rod 102 is not tensioned, even if the tension is relaxed, it is possible to maintain a constant tension.

Therefore, since the driving controller decelerates until the winding drum 103 and the rewinding drum 104 are stopped after the simultaneous stop by the brake, the length of the wire rod 102 is measured by the encoder 112. By rotating the first and second alternating-current motors 107 and 108 by the reverse distance to reverse winding the wire rod 102, the position of the defective wire rod can be moved to the detection plate 125 so that the operator can quickly follow up. It is to be.

On the other hand, referring to Figures 2 to 5 attached to the action of the rewinding device of the wire according to the present invention as follows.

First, the wire rod 102 is guided from the winding drum 103 to the first guide roller 110, and then alternately to a plurality of guide grooves 117a and 121a formed in the fixed roller 117 and the turning roller 121. After being guided in a small way, the guide rod 111 is guided from the fixed roller 117 to the second guide roller 111. At this time, the wire rod 102 guided to the second guide roller 111 is the detection groove ( The position of the defective wire rod is detected while passing through 125a, and the wire rod 102 passing through the second guide roller 111 is coupled to the second guide rod 127 and the lead screw 129 to be reciprocated. After being guided to the prevention roll 134 and the correction roller 133 of 130, it is wound up by the rewinding drum 104.

Here, before starting the first operation, any one of the first and second alternating motors 107 and 108 is operated according to the intention of the operator to allow the turning roller 121 to be described later to be moved to the reference position. It is preferable to operate the equipment, but since this belongs to one method of operating the equipment, the present invention does not limit this. Even if the turning roller 121 is not moved to the reference position, the operation is started when the operation of the equipment starts. The present invention is not limited to this because it automatically moves to the reference position under the control of the controller.

Therefore, when the operator presses the operation start button of the control box (not shown) to start the rewinding operation, the operation control unit transmits power to the rotary shaft 104a of the winding drum 103 and the rewinding drum 104. The first and second alternating-current motors 107 and 108 are driven to guide the first guide roller 110 while the wire rod 102 wound around the winding drum 103 is released, and the first guide roller ( The wire rod 102 guided by the 110 is turned and lowered in the guide grooves 117a and the first guide rod 116 of the fixed roller 117 installed on the first guide rod 116. Since it is alternately outer periphery in the guide groove (121a) of the through, it is sequentially guided to the second guide roller 111 and then re-wound in the rewinding drum 104.

At the same time, the wire rod 102 guided to the first and second guide rollers 110 and 111 has a length of the wire rod 102 that is released by the rotational speed of the winding drum 103 and the rewinding drum 104. The tension or relaxation phenomenon of tension occurs due to the difference in length of the wire rod 102 to be rewound, so that the wire rod 102 can maintain a constant tension.

Here, when the hourly length of the wire rod 102 to be released from the winding drum 103 is longer than the hourly length of the wire rod 102 to be rewound in the rewinding drum 104, a phenomenon occurs that tension is relaxed. The turning roller 121 along the one guide rod 116 is lowered by its own weight, so that the tension is maintained by responding to the relaxation of the tension, and the length of time of the wire rod 102 released from the winding drum 103 is measured again. If the length of the wire rod 102 rewound in the winding drum 104 is shorter than the length of the wire rod 102, the tension of the wire rod 102 is tensioned, so that the length of the wire rod 102 between the rewinding drum 104 and the winding drum 103 becomes short. The turning roller 121 is to maintain the tension while lifting.

In addition, as the turning roller 121 moves up and down, the transfer bracket 120, the first guide pipe 118, and the fixed piece 119 move up and down, and the chain 106 fixed to the fixed piece 119 is fixed. ) Is raised and lowered, so that the lower sprocket 114 is rotated together by the lifting and lowering of the chain 106.

Therefore, when the interlocking gear 122 arranged on the rotary shaft 114a of the lower sprocket 114 and the resistance indicating gear 123 meshed with the interlocking gear 122 rotate, the resistance value of the variable resistor is changed. At this time, the comparison unit compares the resistance value of the variable resistor with the reference resistance value and transfers the resistance to the tension control unit.

When the variable resistance value is input to the tension control unit, the tension control unit compares and calculates the measured resistance value and the reference resistance value in a proportional control manner to control the rotation speeds of the first and second alternating motors 107 and 108. Done.

Here, when the fixing piece 119 of the transfer bracket 120 reaches the center position (reference position) between the upper and lower sprockets 113 and 114, the resistance of the variable resistance indicated by the resistance indicating gear 123 is indicated. The value becomes the reference resistance value '0', and when the transfer bracket 120 moves up and down at the center position (reference position), the resistance value of the variable resistor is increased to '-' value by the inverter connected to the resistance indicating gear 123. When the transfer bracket 120 descends from the center position (reference position), the resistance value of the variable resistor is increased to the '+' value by the inverter, and the tension is kept constant by the PID control algorithm. P (proportional control) calculates the difference (resistance deviation) between a constant tension (resistance value) and a variable resistance to control and gives a control amount in proportion to the deviation value.

That is, when the resistance value is increased to the '-' value by the inverter, the first AC motor 107 is accelerated, but the acceleration range is determined according to the resistance value of the variable resistor, and the resistance value is '+' by the inverter. If the value is increased to increase the second AC motor 108, the acceleration range is to be determined according to the resistance value of the variable resistor.

If the acceleration range is the angle at which the resistance indicating gear 123 indicates the variable resistance means a variable resistance, if the current angle is 0 ° (the reference position of the turning roller 121), the deviation is 100%, The operation control unit applies a reference voltage to the first and second alternating current motors 107 and 108, and if it is + 50 °, the deviation is 50%. If the deviation is -50 °, the deviation is 50%, thereby controlling the speed of the first and second alternating motors 107 and 108 by applying a control voltage corresponding to the deviation of 50% to the first alternating motor 107. To maintain tension.

I (integral control) control refers to adding a control voltage by continuously integrating a deviation of 1 degree when a fine control voltage is required (for example, 1 degree deviation).

D (differential control) control is to give a control voltage in proportion to the angle of the current resistance command gear 123 and the slope of the immediately preceding angle so that the target control voltage can be reached more quickly and flexibly. Since the control algorithm is widely used in industrial sites, the description thereof will be omitted below.

Meanwhile, in the wire rod 102 passing through the detection groove 125a of the detection plate 125 while the wire rod 102 is rewound, the detection plate 125 has a '+' terminal connected thereto and the main body 109. The wire rod 102 is connected to the '-' terminal because the '-' terminal is connected to any one of the fixed roller 117, the turning roller 121, and the first and second guide rollers 110 and 111. Since the wire rod protrudes to the outer diameter of the wire rod 102, the detection groove 125a passes through the detection groove 125a, and a signal is generated while the wire is contacted with the detection groove 125a. Thus, the position of the defective wire rod is detected.

When the defective point of the wire rod 102 is detected, the operation control unit causes the encoder 112 to measure the length of the wire rod 102 to be transferred, and at the same time, the first and second alternating motors 107 and 108. When the motor is decelerated to a predetermined speed, the brake stops the winding drum 103 and the rewinding drum 104 with a brake and stops the first and second alternating motors 107 and 108. .

Therefore, when the first and second alternating motors 107 and 108 and the wire rod 102 are stopped, the operation control unit first and second alternating motors 107 and 108 by the transport distance measured by the encoder 112. ) By reverse rotation and stop so that the position of the defective wire rod can reach the position of the detection plate 125, the operator can take action such as cutting the wire protruding to the outer diameter of the wire (102). .

Meanwhile, the wire rod 102 guided to the second guide roller 111 is connected to the second guide pipe 128 inserted into the second guide rod 127 and a connecting plate 128a at a lower portion thereof, and leads to a lead screw ( Guided to the correction roller 133 coupled to the conveying body 130 fastened to the 129, to prevent the wire rod 102 from biased left and right by forward and backward reciprocating immediately before being guided to the correction roller 133 Through the prevention roll 134, the re-winding is started and at the same time the alignment control unit is rotated by the third alternating current motor in accordance with the rotational speed of the second alternating current motor 108, the rotational speed of the third alternating current motor The wire rod 102 may be guided to the rewinding drum 104 in the correction roller 133 in accordance with the rewinding direction, and the transfer body 130 may lead the lead screw 129 and the second guide rod. When moving along one side of the front and rear in accordance with 127, the sensing unit 131 provided on the lower portion of the conveying body 130 is fixed bar 13 5) If it is detected by any one of the limit sensor 132 installed in the front, rear, it means that the direction in which the wire rod 102 is re-wound is reversed, the alignment control unit is inverted the rotation direction of the third AC motor lead By rotating the screw 129 reversely, the correction roller 133 can guide the wire 102 uniformly according to the rewinding direction of the wire 102.

As described above, in the present invention, in rewinding the wire rod to the supply roll used in the wire coating process, the winding drum and the rewinding drum can be simultaneously rotated to rewind at a high speed, thereby improving the working speed, thereby increasing production efficiency. To increase the reliability of the product by maintaining the constant thickness of the wire by maintaining a constant tension even at high speeds in response to changes in the tension force of the wires generated at high speeds. Even after detecting a bad point of the wire rod generated by the wire protruding into the outer diameter of the wire rod, the operator can quickly find the bad spot without solving the tension and solve the problem.

In addition, it is possible to rewind high-quality wire while using a low-cost AC motor without using an expensive DC motor, thereby making it possible to rewind high-quality wire while producing / distributing equipment at a low price.
