Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a numerical control device for a winding machine, and more particularly to a numerical control device for a winding machine that performs multi-layer aligned winding on a coil bobbin rotating at high speed at equal pitch intervals.

[0002]

2. Description of the Related Art When performing multi-layer alignment winding on a coil bobbin at equal pitch intervals, if the winding width is constant at the starting end side and the ending side of the traverse shaft, the bobbin is folded back when the traverse shaft is folded back. Although the winding could be continuously performed without lowering the number of revolutions, the appearance of bobbins that require aligned winding with an equal pitch, in which the winding width differs for each layer, appeared This is accomplished by stopping the rotation of the bobbin, moving the traverse shaft to the winding start position of the next layer, and then winding.

SUMMARY OF THE INVENTION In the prior art,
The first problem is that when winding is performed in a shape in which the winding width is different for each layer, it is necessary to create an aligned winding program for each layer. The reason is that since it is not possible to continuously perform aligned windings having shapes with different winding widths, it is necessary to create a program for each layer, which requires program creation time.

The second problem is that it is necessary to create a program for moving from the winding end position of the previous layer to the next winding start position. The reason is that since windings with different pitches cannot be made without stopping the bobbin rotation, it is necessary to create a program for shifting each layer, which requires program creation time.

A third problem is that the bobbins that rotate at high speed are stopped for each program in order to sequentially execute the created programs. The reason is that when a plurality of NC programs are executed, the acceleration / deceleration operation always occurs for each program. Therefore, as the number of layers increases, the accumulation of acceleration / deceleration time increases and the productivity cannot be increased.

It is an object of the present invention to solve the above-mentioned problems in a winding machine having a shape in which the winding width is different for each layer when performing multi-layer aligned winding of equal pitch. To provide.

Next, the operation of the embodiment of the present invention will be described.
This will be described in detail with reference to FIGS. FIG. 2 is a flow chart showing the operation of the present invention. First, the winding process, step 19 is the bobbin movement amount calculation process of the first layer based on the NC program input in the data input section, and step 20
Is a speed calculation process of the traverse axis based on the set bobbin rotation speed and pitch data. Step 21 is a movement amount of the bobbin based on the acceleration / deceleration time constant and the bobbin rotation speed, and a movement of the traverse shaft that operates in synchronization with the bobbin rotation. Step 22 is a process of calculating the amount and speed, and step 22 is a process of calculating the moving amount of the bobbin at the constant speed rotation and the speed of the traverse axis that operates in synchronization with the bobbin rotation, from the data calculated in steps 19 to 21. is there. Next, Steps 23 and 24 are variable winding width processing, and Step 23 checks the data of the input side NC-side shift amount I and end-side shift amount J. If I = 0 and J = 0, the step is performed. 24
Step 2 of the variable winding width function is executed.
5, the conventional constant pitch and constant winding width processing is performed.

FIG. 3 shows details of the winding width variable function processing, and the winding processing of eight types of shape patterns is performed by the data of the shift amounts I and J. I is a shift amount on the starting end side, and when I> 0, the shape pattern has a larger winding width on the starting end side, and the shape patterns A, B, C, 26, 27, 28 are formed depending on the condition of the starting end side shift amount J.
Shape pattern.

When I <0, the shape pattern has a winding width that becomes smaller on the starting end side and becomes the shape patterns D, E, F, 29, 30, and 31 depending on the condition of the end side shift amount J.

When I = 0, the winding width is the shape pattern on the starting end side, which is unchanged, and becomes the shape patterns G, H, 32, and 33 depending on the condition of the shift amount J on the ending side.

As described above, when I> 0, the winding width shifts in the direction in which the winding width increases at the winding end of the even layer, and in the case of I <0, the winding width shifts in the direction in which the winding width decreases at the winding start of the odd layers other than the first layer. To do. Similarly, when J> 0, the winding width is shifted in the direction in which the winding width is increased at the end of winding of the odd layers, and when J <0, the winding width is shifted in the direction in which the winding width is decreased at the beginning of winding of the even layers. That is, the feed pitch and speed of one winding at the winding start or winding end of the traverse shaft are changed according to the conditions of I and J without changing the rotation speed of the bobbin, and the winding width and the bobbin rotation of each layer are changed according to the shift. It is realized by calculating the movement amount.

59 is a feed rate of P0 of 38. Each data is calculated as follows for each layer. (1) Winding width Xn First layer X1 = X0 Second layer X2 = X0 + j Third layer X3 = X0 + i + j Fourth layer X4 = X0 + i + 2j Nth layer Xn = X0 + (A-1 ) * I + A * j A = n / 2 (2) Number of turns Kn Kn = Xn / P0 (3) Traverse shaft speed F × (P0 pitch feed speed) Fx = P0 * Fz / 60 (4) Traverse shaft speed Fsi (i (Shift speed) Fsi = i * Fz / 60 (5) Traverse axis speed Fsj (j shift speed) Fsj = j * Fz / 60 (6) Traverse speed during shift i Shift Fxi = Fx + Fsi j Shift Fxj = Fx + Fsj or more By recalculating and winding up to the final n layers,
Realized by inputting the shift amount as a parameter to one block of NC data for various shaped windings such that the start position and the end position are shifted for each layer, and the aligned winding without reducing the work rotation speed during the shift. Therefore, there is an effect that the program creation time and the production time can be shortened.

[0018]

The first effect of the present invention is to stop the bobbin rotating at a high speed for each layer by setting the shift amount as a parameter in the winding having a shape in which the winding width changes for each layer. Without doing so, the aligned winding can be continuously performed to improve the productivity. The reason is that, compared to the conventional technique in which the bobbin rotating at a high speed is stopped for each layer, the time T (se
c) is the acceleration / deceleration time constant t (sec) and the number of layers is n, then T
= (N-1) t.

The second effect is that it can be applied to windings of various types. The reason is that the winding having the shape pattern shown in FIG. 3 can be realized by the setting data of the shift amounts I and J input as the parameters of the NC program.
