Description

[Detailed description of the invention] (Field of industrial application) The present invention is based on a twisting device of a winding machine, more specifically, an automatic winding machine that winds the end of the winding wire multiple times using a wire supply nozzle. , relates to a twisting device for a winding machine that uses the rotation of a spindle to perform twisting.

(Prior Art) An automatic winding machine is known in which a bobbin is fixed to a spindle, the spindle is rotated at high speed, and a wire is supplied while a wire supply nozzle is moved to perform winding.

FIG. 6 is a diagram for explaining an example of winding of an automatic winding machine and winding of the ends of the winding.

For winding, fix the bobbin 1 to the spindle 4,
This is carried out by rotating the wire rod supply nozzle 2 in the direction indicated by arrow P in the figure while rotating the spindle 4 at high speed.

To wind the wire, stop the spindle 4 at a position where the terminal pin 1a of the bobbin 1 is parallel to the wire supply nozzle 2, and rotate the wire supply nozzle 2 in the direction indicated by the arrow r in FIG. 6B. This is done by

In this way, with automatic winding machines, winding ends were twisted using only one wire, and therefore sufficient strength could not be obtained. For this reason, during the work of winding the ends of the windings or when using the wound coil, the winding portions were sometimes broken. In addition, if a single wire was used, there was a possibility that the electrical connection would become uncertain.

In order to solve this problem, a twisting device for twisting the winding ends has been proposed.

(Problem to be solved by the invention) Conventionally, this type of device had to be installed separately from the winding machine, which resulted in high costs, inconsistent operation, and poor operability as an automatic machine. Was.

The purpose of the present invention is to incorporate a twisting device into the winding machine by winding the wire using a wire supply nozzle and twisting the wound wire using the rotation of the spindle, thereby achieving a simple configuration and ease of use. The purpose is to provide a twisting device for a winding machine.

(Means for Solving the Problems) In order to solve the above problems, the twisting device for a winding machine according to the present invention supports a bobbin on a rotating spindle, and has a wire supply nozzle that can be moved three-dimensionally to the bobbin. A winding machine that winds a wire while supplying the wire with a twisting hook that is provided at the tip of the spindle and twists the wire by rotation thereof, and a twisting hook that moves forward and backward in a direction intersecting the operating line of the wire supply nozzle to move the wire. A twisting end locking pin is provided for locking the twisting end of the wire rod, and the twisting end locking pin is moved onto the operation line, and the wire rod is connected to the twisting hook and the twisting end by the wire supply nozzle. After winding between the locking pins a preset number of times, the twisting hook is rotated a preset number of times by rotation of the spindle to twist the wound wires. has been done.

According to the above structure, the object of the present invention can be completely achieved.

(Example) Hereinafter, examples will be described in more detail with reference to the drawings and the like.

FIG. 1 is a diagram showing an embodiment of a twisting device for a winding machine according to the present invention.

A thin tube is used for the wire supply nozzle 2,
It is supported by a nozzle holder 21. After the wire 3 is given tension by a tension pulley 23a of a tension device 23, it is supplied to the pipe portion of the wire supply nozzle 2 via the pulley 21. The wire supply nozzle 2 is movable in the vertical, horizontal, and longitudinal directions in the figure, and is driven for three-dimensional position control by a microcomputer according to a predetermined program.

A twisting hook 41 is attached to the tip of the spindle 4. The twisting hook 41 is for twisting the wire rods 3, and rotates using the rotation of the spindle 4.

The twisting end locking pin 5 is attached to the tip of the rod of the air cylinder 51, and when the rod is pushed out, it advances onto the operating line connecting the operating position of the wire supply nozzle 2 and the twisting hook 41, and the rod is pushed out. When it is pushed in, it retreats from the operating line. The twisted end locking pin 5 is relatively thin. This is to reduce the size of the annular portion that is formed when the twisted end locking pin 5 is removed from the twisted portion 31 of the wire rod 3, as will be described later.

The wire clips 6 are used to clip the ends of the windings. The wire clamp 6 clamps the wire 3 by operating an air cylinder 61 using a manual switch.

Next, the operation of the embodiment of the twisting device for a winding machine according to the present invention will be described with reference to FIGS. 2 to 5.

First, the tip of the wire 3 is manually stretched to the position of the wire clip 6, and the air cylinder 61 is operated to clamp the wire 3 with the wire clip 6 as shown in FIG.

The wire supply nozzle 2 is driven by the winding number instruction signal from the control section, moves between the twisting hook 41 and the twisting end locking pin 5, and winds the wire 3 as shown in FIG. turn. After winding, the wire supply nozzle 2 is retracted to the right of the twisting hook 41.

Next, the spindle 4 is rotated a predetermined number of times in response to an instruction signal for the number of twists from the control section, thereby forming a twist section 31 in the wire 3, as shown in FIG. In addition, depending on the type of wire 2, etc., the control section has
The number of windings and the number of twists can be set in advance.

Furthermore, as shown in FIG.
1 operates, the twisted end locking pin 5
After retracting, the wire rod supply nozzle 2 advances to the left in the figure, and a part of the twisted portion 31 is inserted into the wire rod supply nozzle 2.

After this operation, as shown in Figure 6 above,
Twist the twisted part 31 onto the terminal pin 1a of the bobbin 1,
Furthermore, wind the wire on bobbin 1.

When the winding is completed, the ends of the winding are twisted together in the same manner as described above (FIGS. 2 to 5), and the winding ends are twisted to the other terminal pin of the bobbin 1 to complete the entire operation.

(Effects of the invention) As explained in detail above, according to the invention,
Since the wire is wound by the wire supply nozzle and the wound wire is twisted using the rotation of the spindle, a simple and inexpensive twisting device can be provided.

In addition, by integrating it into an automatic winding machine,
It also has the effect of being easier to control and improving operability.
