Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a filament winding machine for producing a coreless filament having a wound coil portion and legs bent at right angles to the coil portion.

Generally, in this type of filament winding machine.

A tungsten wire pulled out from a predetermined direction is engaged with a mandrel led from a direction perpendicular to the tungsten wire, and the mandrel is rotated and moved in a direction perpendicular to the tungsten wire, and when a predetermined length is completed, the layer is removed from the mandrel. By cutting.

Filament is manufactured without a core wire.

In conventional filament winding machines, the rotation from a single main motor is driven by a cam. The rotation and movement of the mandrel was controlled by mechanically changing the speed or converting it into mechanical linear motion using links, gears, etc. In this way, when movement is controlled mechanically, the pitch of the filament, the number of turns, and the angle of the legs are adjusted using a cam.
There were disadvantages in that the gears, etc. were too small, and that it took time and money to replace nine parts when changing.

SUMMARY OF THE INVENTION An object of the present invention is to provide a filament winding machine in which the winding pitch, number of turns, leg angle, etc. can be easily adjusted.

According to the present invention, there is provided a means for feeding a wire to become a filament in a predetermined direction, a means for cutting the wire, and a main body that controls the operation of the feeding means and cutting means by rotating a camshaft.

Referring to FIGS. 1 and 2, a pedestal 18 shown in FIG. 1 supports each of the above-mentioned devices, and a variable speed motor 19 is housed inside the pedestal 18 as a main motor. The rotation of this variable speed motor is transmitted via a timing belt 20 to a camshaft 21 shown in FIG. A cam group 22 consisting of a plurality of cams is attached to the cam shaft 21, and the cam group 22 is connected to the feed device 13. Cutting device 14
It is connected to a jig 15 for forming one leg. In this configuration,
The rotation of the variable speed motor 19 is connected to the feeding device 13 and the cutting device 14.
These devices and jigs can be controlled according to the operation timing of the variable speed motor 19 that is transmitted to the one-leg molding jig 15. Further, a rotary encoder 24, which will be described later, is connected to the camshaft 21 and generates an output signal according to the rotation of the variable speed motor 19.

Returning to FIG. 1, the rotary encoder 24 (second
An electric signal corresponding to the rotation angle of the variable speed motor 19 output from the variable speed motor 19 is input to the IC board group 26 in the control panel 25. This IC board group 26 includes a synchronization circuit, a clock generation circuit, and a count control circuit.

It includes input/output circuits, etc., and the output signal of the IC board group 26 is sent to the DC motor controller 29.3 in the switchboard 27.
Enter 0. This DC motor controller 29.3
0 output signal causes the DC servo motor 31. The traverse DC servo motor 32 is driven. The rotational DC servo motor 31 controls the rotational movement of the mandrel 17 about its axis, while the traverse DC servo motor 32 controls the movement of the mandrel 17 in its longitudinal direction. Also, inside the switchboard 27.

A further variable speed motor controller (not shown) for driving the variable speed motor 9 is provided.

Referring to FIG. 3, the relationship between the mandrel 17, the rotating DC servo motor 31, and the traverse DC servo motor 32 in FIG. 1 is specifically shown. Two spur gears 34 are mounted inside the gear 33, and the rotation of the one-rotation DC servo motor 31 rotates the mandrel 17 around its axis via the spur gears 34. On the other hand, when the traverse DC thermomotor 32 rotates, the male screw 35 rotates, causing the body 33 to move linearly along the guide bar 36, and thus the mandrel 17 to move in its longitudinal direction. Further, a convex portion 3 is provided on the upper part of the mandrel 17.
7 is provided, and engages the tungsten ill on the -r channel 17 by means of a nicotine convex portion 37, as will be described later.

Next, the operation of this filament winding machine will be explained with reference to FIGS. 1 to 3. First, the tungsten wire 11 wound around the spool 12 is guided through the feeding device @13 and the cutting die 14a as shown in FIG. In this state, the power is turned on by operating the command switches 39, and the variable speed motor 19. D for rotation
C buzzer motor 31. Traverse DC servo motor 3

Adjust the position of the cutting device 14, etc. The foot shaping jig 15 is adjusted to mold the foot into a desired shape. On the other hand, the number of turns of the filament,
40 digital switches for pitch, number of back turns, etc.
Set with . The number of turns is not limited to integers, but also includes decimal parts.

The angle of the legs can be determined by the number of turns. Then, set the device to its initial state.

After completing the adjustment and setting of the device as described in ``2'' above, the operator presses the ``5TA'' button on the control channel 38.
Press the RT" yl? button.Then, the device will automatically produce a filament as described below. First, the tungsten wire 1 is fed by the feeding device 13 for a length corresponding to the length of the filament. At that time, the man 1゛rel 17
The tungsten wire 11 passes between the tungsten wire 11 and the convex portion 37 provided above. Tungsten wire 11 is mandrel 17
The coils intersect with each other at right angles to each other, and stop at a position beyond the V-drel 17 and at a length corresponding to one leg of the coil from the mandrel 17. Next, the foot is molded using the single-leg molding jig 15. When the variable speed motor 19 reaches a predetermined rotation angle, the tungsten wire 11 is moved to the convex portion 3 by the one-rotation DC servo motor 31 and the traverse DC servo motor 32.
7 and wind it onto the mandrel 17 in a pinch for the desired number of turns, then reverse the rotation of the shaft by the number of turns, and the engagement by the protrusion 37 on the mandrel 17 is released. When the bond is released, the mandrel 17 becomes D for traverse.
It is moved back from the winding position by the C servo motor 32.

The tungsten wire 11 wound in a coiled manner around the mandrel 17 in this manner is cut by the cutting device 14 at the length of the other leg to form a filament. The filament thus obtained is housed in the theta 16. When these operations are completed, the device returns to its initial state and thereafter repeats the operations described above.

As described above, filaments having the same shape are automatically manufactured, but adjustments to the pitch, number of turns, etc. of the filament can be easily made using the digital switches 40 on the control panel 38.

As is clear from the above description, there are two aspects of the present invention.
