Abstract

PURPOSE:To suppress impact on a wire as low as possible and to realize automatic high speed operation by correcting a wire drum speed command based on the diameter of residual wire wound on the wire drum and previously input data. CONSTITUTION:A control section takes in the position of winding shaft at the time of winding operation and the diameter of wire drum, and calculates reduction of the wire diameter on the wire drum 31 and the variation of wire speed due to increase of the coil diameter for every winding work. Rotary speed of a wire drum drive motor 24 is synchronized with the feeding speed of wire to be wound. Upon provision of an output signal from a tensile force detector 36 in a tensile force applying mechanism 30 for applying a constant tensile force onto the wire 28, the output is additionally employed in the control of the rotary speed of the wire drum drive motor 24. By such arrangement, no impact is applied onto the wire at the start of winding operation resulting in a high quality coil through an automated high speed winding process.

Description

Detailed Description of the Invention [Object of the Invention] (Industrial Field of Icheon) The present invention relates to a coil winding device for use in a rotating electric machine.

(Prior Art) Conventionally, when winding a coil that is attached to the iron core of a rotating electrical machine, the tip of the electric wire 3 pulled out from the wire drum 2 while the winding machine 1 is stopped, as shown in FIG. is fixed to an elongated winding form 9 attached to a winding shaft 8 via the drum 5, wire guide 6 and pulse generator 7 of the tension applying mechanism 4.

At this time, the longitudinal direction of the winding form 9 is in a horizontal state. 'When the winding machine 1 starts operating, a preset sinusoidal speed command is given from a microcomputer (not shown) to a controller (not shown), and the servo motor 10 starts rotating. The reason why the speed command set in advance is made into a sine wave shape is to reduce the rotational speed before and after the winding form 9 is in a horizontal state, in order to prevent the winding wire 3 from hitting the winding wire 3 before and after the horizontal state. Because I want to. Feedback is applied by the rotary generator 11 connected to a controller (not shown), and the servo motor 10 is controlled to a predetermined speed. When the rJs line 3 is sent in, the pulse generator 7, which is its speed detector, generates a pulse signal. The generated pulse signal is input to a microcomputer (not shown), and its output is given to a controller (not shown), which drives the servo motor 13 of the wire drum 2 as a speed command. At this time, the tension applying mechanism 4
4, a constant tension is applied to the wire 3, and its [I! The tension detector 15 detects the position of the drum 5 of No. 1, and the value and m;
t; L is always controlled so that the commands of the microcomputer are at a balanced position. A rotary generator 16 directly connected to the wire drum 2 provides feedback so that the servo motor 13 reaches a predetermined speed.

(Problem to be Solved by the Invention) According to such a conventional first wire device, when the winding machine 1 starts winding, the feed amount of the wire 3 is detected by the pulse generator 7, and the amount of feed is detected by the pulse generator 7. Since the speed command is given to the servo motor 13 of the wire drum 2 based on the value, the feeding speed of the wire 3 tends to be slow to follow the speed of the wire 3 that is actually attached to the winding form 9. As a result, the deflection of the drum 5 of the tension applying mechanism 4 increases. In other words? l! 9
A large tension will be applied to the electric wire 3 wound around the coil.

In addition, when winding at high speed, contact between the electric wire 3 and the pulse generator 7 causes slippage, resulting in a pulse generation error, and the deflection of the drum 5 becomes large, causing a large shock to the fui 3 and causing the wire 3 to slip. Local elongation occurs, which impedes high-speed automation of winding work and causes deterioration in the quality of the coil.

In order to solve these problems, it is an eleventh object of the present invention to provide a winding device for a four-turn electric machine that can reduce shock applied to electric wires as much as possible, thereby increasing speed and speed.

[Structure of the Invention (Means for Solving the Problem) Masaaki Moto's winding device for a rotating electrical machine includes a human power section for taking in human power data of winding conditions, and a wire drum speed command from this human power data. A control section for controlling the entire device that calculates and stores the wire drum speed command corresponding to the signal value taken in from the winding shaft position detector and the wire drum diameter detector attached to one end of the winding shaft is provided. A tension applying mechanism is provided, which includes means for searching and outputting in a control section, and a tension detector located between the wire drum and the winding form to apply a constant tension to the electric wire wound around the winding form and detecting the tension. The present invention is characterized in that the rotation of the wire drum drive motor is controlled so as to apply a constant tension to the wire being wound in accordance with the wire drum speed command and the output signal of the tension detector.

(Function) According to the winding device of the present invention, there is an input section for taking in manual data on winding conditions, and a control section for controlling the entire device that calculates and stores a wire drum speed command from this manual data. and means for the controller to search and output a wire drum speed command corresponding to signal values taken in from a sleeve position detector and a wire drum diameter detector attached to one end of the winding shaft. Therefore, the winding sleeve position and wire drum diameter at the same time of winding are taken into the control unit and calculated by adding the decrease in the diameter of the wire remaining on the wire drum for each winding direction and the change in wire speed due to an increase in the coil diameter of the winding form. By outputting a sinusoidal wire drum speed command, the rotational speed of the wire drum drive motor is synchronized with the feeding speed and the output from the tension detector of the tension applying mechanism that provides a constant tension. When a signal is generated, this output is also applied to control the rotational speed of the wire drum drive motor, so that a constant tension is always applied to the wire being wound around the winding form during the winding operation. Can be done.

(Example of Length) An embodiment of the daylight device for a rotating electric machine according to the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, an elongated winding form 22 is attached to a winding shaft 21 of a winding machine 20, and is rotated by a motor 24 controlled by a speed control device 23. A winding shaft position detector 25 is connected to the motor 24 . The output of the winding shaft position detector 25 is connected to a control section 26 that performs calculation and control of the entire winding device.

Further, a human power section 27 is connected to the control section 26 to take in human power data necessary for operation. The electric wire 28 attached to the winding form 22 has two wire guides and a tension applying mechanism 3.
0 from the wire drum 31. This tension applying mechanism 30 includes a support 34 that supports a lower ram 33 that is rotatably supported on a shaft 32 at one end and has an electric wire 28 at the other end, and an electric wire between the support 34. An air cylinder 35 for applying a constant tension to the column 28 and a tension detector 36 for detecting the tension state based on the inclination of the column 34 are attached.

The wire drum 31 is rotated by a servo motor 38 equipped with a rotary generator 37. The output of the four-turn generator 37 is connected to three servo controllers 40 that are speed controllers. The electric wire 2 of the wire drum 31 is placed on the right side of the wire drum 31.
A drum diameter detector 41 that receives ultra-8 waves for measuring the remaining winding diameter of the drum diameter detector 4 is installed.
The signal No. 1 is connected to the control section 26 . The wire drum speed command calculated by the control unit 26 in accordance with the winding shaft position based on the human power data and the wire drum diameter is transmitted to the tension detector 3.
6 and an adder 42 connected thereto, and its output is connected to a servo controller 40.

The speed command given from the control section 26 to the winding former speed control device 23 is a constant voltage corresponding to the number of four rotations inputted from the input section 27. Further, the control unit 26 sends the adder 4
As shown in Figure 3, the speeding order given to 2 is low in the horizontal state (0, π, 2π) in the longitudinal direction of the elongated shape, and is high in the vertical state. It is wavy. This value will be adjusted as appropriate depending on the size of the coil and the thickness of the wire. Furthermore, as the wire 28 is wound around the winding form 22, the winding diameter of the winding form 22 gradually increases, and conversely, the wire drum diameter gradually becomes smaller, and the signal of the drum diameter detection S41 also becomes feminine, causing the wire drum speed to become smaller. As for the command, a value calculated for each winding is output in the direction from v1 to v2.

Next, the operation of this embodiment with the above configuration will be explained. First, while the line machine 20 is stopped, the tip of the electric wire 28 pulled out from the wire drum 31 passes through the drum 33 on the side of the tensioning machine 30, the two wire guides, and the winding form attached to the winding shaft 21. 22 is held captive. At this time, the winding form 22
The longitudinal direction of is horizontal. After fixing this electric wire 28, when data such as the winding shaft setting rotation speed, number of windings, winding shape, coil circumference, wire diameter, number of manufactured items, etc. required for operation are entered manually from the input section 27, these values are input to the control section. 26.

Thereafter, when a start signal is manually inputted from the input section 27 to the control section 26, the speed control device 23
Calculate the value of the reel speed command to the reel speed command,
Based on the data from the drum diameter detector 41, a sinusoidal wire drum speed command is calculated as shown in FIG.
Store it as data corresponding to rotation.

When this calculation is completed by the control unit 26, the on-line machine 20 starts operating. A winding shaft speed command is given from the control section 26 to the speed control device 23, and the winding form 22 starts rotating by the motor 24. When the motor 22 rotates, the winding shaft position detector 25
also works. The position of the winding shaft 21 is determined by the winding shaft position detector 2.
The wire drum speed command corresponding to the position of the winding shaft 21 is retrieved from the stored data, and this value is given to the speed controller 39 via the adder 42. The servo motor 38 starts rotating four times, and the wire drum 31 rotates at the same time to supply the electric wire 28.

In this way, the position of the winding shaft 21 is always input to the control unit 26 from the winding sleeve position detector 25, and the wire drum speed command is searched from the data stored in the control unit 26 based on the position, and the value thereof is determined. is output to the adder 42.

On the other hand, the electric wire 28 is pulled as the winding form 22 begins to rotate, and tries to pull the drum 33 of the tension applying mechanism 30. However, since the wire drum 31 has already started rotating due to the wire drum speed command output from the control section 26 and has started to supply the electric wire 28, the tension applying mechanism 30
The drum 33 feeds the wire 28 to the winding form 22 with constant tension while remaining in substantially its original position.

As the rotational position of the elongated winding form 22 changes, the speed of the crest line 28 is slowest near the horizontal position in the longitudinal direction of the winding form 22, and the wire drum speed command from the control unit 26 also becomes smaller. Therefore, the rotation of the wire drum 31 becomes slower. Similarly, when the co-rotation position of the mold 22 is near the vertical position,
The speed of the electric wire 28 is the fastest, and the wire drum speed command from the control unit 26 is also the largest, so the wire drum 31 can rotate faster. In this way, t1 of volume Jt222
The wire drum 31 rotates four times in synchronization with the supply speed of the electric wire 28 due to the position change.

Furthermore, as the electric wire 28 is wound around the winding form 22, the winding form 2
Since the winding diameter of No. 2 gradually increases, the fjt feeding rate of the electric wire 28 per rotation of the winding form 22 increases. On the other hand, since the number of electric wires 28 in the wire drum 31 decreases, 'r8!' of the wire drum 31! ! ; The remaining diameter of I28 becomes smaller, and the wire 28 per four rotations of the wire drum 31 becomes smaller.
supply rate becomes smaller.

Therefore, in this embodiment, the winding diameter of the winding form 22 is increased by &
．． j L is the circumference. Based on the wire size input data, the unwound diameter of the wire 28 of the wire drum 31 can be reduced by k.! In addition, based on the human input data from the drum diameter detector 41, the controller 26 calculates the wire drum speed command for each winding and outputs the supplemented value to the adder 42 so that the wire drum speed command increases. As a result, the wire drum 31 increases the uniform rotational speed by 1ξ for each winding, and correspondingly increases the feeding speed of the wire 28 to the mold 22, which always rotates at a constant speed, to increase the speed of the wire 28 in the winding form 22. Maintain a constant tension on 28.
．． I will do it.

As described above, according to this embodiment, the wire drum 31
The remaining diameter of the electric wire 28 is determined by the drum diameter detector 41.
In order to directly input the wire drum speed command to the control unit 26 and correct the wire drum speed command, the wire drum 31's electric power 1! Smooth winding is possible regardless of the size of the remaining diameter of the wire 28, and there is no shock to the electric wire 28 at the start of winding. Further, since the winding device is finely controlled so that a constant tension is applied to the wire 28 at the same time, the winding device can be operated at high speed and automated.

In addition, in this example, the diameter of the remaining wire 28 on the wire drum 31 is measured using a drum detector (ultrasonic, etc.).
A similar function can also be achieved by bringing a roller or the like into contact with the unwound diameter of the electric wire 28 of the wire drum 31 and detecting a change in the diameter.

In addition, the initial value of the unwound diameter of the electric wire 28 of the wire drum 31 is input as manual data and controlled? If data corresponding to the decrease in the wire drum diameter for each winding and the maximum amount of the winding form diameter are stored in advance in B26, and the widening process is performed using this data,
It is also possible to give a wire drum speed command that can perform the same function without measuring the unwound diameter of the electric wire 28 of the wire drum 31 with a drum diameter detector.

[Effects of the Invention] According to the winding device for a rotating electric machine of the present invention, the value from the means for detecting the unwound diameter of the electric wire on the wire drum at the same time as winding;
The rotation of the wire drum is controlled to be synchronized with the wire removal speed of the winding form by capturing a wire drum speed command for each winding based on the day shape diameter calculated from data manually calculated in advance. Therefore, since a wire with a constant tension is always supplied, smooth winding is possible regardless of the diameter of the wire remaining on the wire drum. T+
The shock of starting at 7am disappeared and the weather was high. A coil of SIJ quality is obtained. Furthermore, since the winding device is finely controlled so that a constant tension is applied to the wire at the same time, it is possible to speed up and automate the winding device.
