Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding machine, and more particularly to a winding machine for winding one bobbin with different kinds of wires.

[Background of the Invention]

This type of winding machine is equipped with a winding unit for each wire, and each winding unit has a nozzle for guiding and feeding out the wire, and a entanglement mechanism. The winding of different types of wires is performed by alternating the winding units. For example, in a transformer coil winding machine, when a primary coil is wound on a bobbin by one winding unit, this winding unit is replaced by another winding unit, and the primary winding is replaced by the alternate winding unit. The secondary coil is wound on the coil. However, in such a structure, not only the space corresponding to the plurality of winding units but also the space for installing the alternation mechanism is required, so that the machine becomes large and the structure is complicated. In particular, when a machine that winds a large number of bobbins at the same time is configured, the structure becomes complicated, and the entire machine becomes large and heavy.

[Object of the Invention]

The present invention provides a winding machine capable of winding a plurality of types of wires on one bobbin, and having a simple structure and a compact structure.

Assuming three orthogonal axes (where the X axis is the paper surface). Vertical), a plurality of spindles (11) in the X-axis direction, each of which has a bobbin (10) mounted concentrically, are arranged, and the spindles are aligned in the Y-axis direction. The two spindles are separated from each other in the Z-axis direction, and Y

In b), since different types of wires can be guided and drawn out, the type of winding work can be exchanged by changing the nozzle. Since the line type can be changed (that is, the nozzle can be changed) by removing the nozzle base from the chuck and mounting a new nozzle base on the chuck, the setup can be changed easily and quickly.

Example of Invention

In this winding machine, each of the spindles 11 supporting the bobbin 10 has two wire holding mechanisms 12a and 12b for fixing and cutting the wire when forming a winding, and a nozzle 13a for guiding different kinds of wires. And 13b.

As shown in FIG. 2, the bobbin 10 has a core 16 provided between a pair of flanges 15, and a primary coil and a secondary coil are formed on the core 16. (First
The two sets of pins 17a, 17b and 18a, 18b are binding pins for these coils, and they are located at right angles to the central axis of the bobbin and are implanted in one of the flanges.

A plurality (three in this example) of spindles 11 in the X-axis direction (perpendicular to the paper surface) are arranged in a line in the Y-axis direction at regular intervals. Each spindle is held by a base of the winding machine via a bearing, and a rear end (not shown) is transmitted to an electric motor installed on the base of the winding machine. A bobbin holder is provided at the tip of each spindle 11 so that the bobbins can be supported with their central axes aligned.

The wire holding mechanism 12a and the wire holding mechanism 12b are spindles.
They are arranged symmetrically with respect to the central axis of 11. Each wire holding mechanism includes a turntable 20. Each turntable is mounted parallel to the spindle (ie in the X-axis direction) and is mounted on a shaft 21 (FIG. 2) held by bearings on the base so that it can rotate about it. It has become.
Pins 22 are planted in each turntable 20. These pins entangle the wires as described below.

Nozzles 13a and 13b are also arranged with respect to the spindle 11. The nozzles 13a, 13b are arranged with their tips facing the spindle and are fixed to the nozzle stands 23a, 23b, respectively. The nozzle itself is a known one,
The large diameter wire 13a can be guided, and the thin wire 13b can be guided by the nozzle 13b.

The nozzle bases 23a, 23b are in three axial directions orthogonal to each other, that is, x, y, z
It can move in the axial direction and can further rotate about the y-axis. The x-axis is the direction of the rotation center axis of the spindle 11.
These movements are selectively imparted to each nozzle base in this winding machine. For this purpose, the winding machine base has a table that can move in the x and y axis directions.
A table movable in the z-axis direction is attached to the table, and a chuck is rotatably supported on the table. In the drawing, the pedestal 25 is shown only partly and is provided with shafts 30 arranged opposite each other. Arms 27 are attached to these axes 30. As shown in FIG. 3, a chuck 28 is attached to each arm so as to be rotatable about an axis 29. The nozzle base is related to the winding. In the drawing, only the nozzle base 23a is held by the chuck 28, and the movement of the table allows the movement in the x and y axis directions.
The vertical movement of 5 moves the z-axis, and the rotation of arm 27 rotates the y-axis. The nozzle base 23b not involved in winding is placed on the base of the winding machine,
You have to wait until you get involved in the winding. The table and the table are moved by a servo motor, and the chuck is rotated by a pneumatic cylinder arranged between the table and the arm.

(See FIG. 2) The wires 26a and 26b pass through the nozzles 13a and 13b, respectively, and the tips are entwined with the pins 22 provided on the wire holding mechanisms 12a and 12b. The end portion on the opposite side of the wire, that is, the end portion (not shown) is connected to a wire supply mechanism (not shown) via a tension mechanism.

The winding is performed by forming the primary coil and the secondary coil on the bobbin 10 as described above. The primary coil is formed by the wire 26a and the secondary coil is formed by the wire 26b.

The winding work of the primary coil will be described. The drawing shows each nozzle 13
It shows a state in which a is rotated around the entwining pin 17a by the nozzle base 23a, and the wire 26a is entangled in the pin 17a of each bobbin by this rotational movement of the nozzle. When the entanglement is completed, each rotary table 20 is rotated counterclockwise about the shaft 21, and each wire is cut between the pin 22 on the wire holding mechanism and the pin 17a on the bobbin. When the cutting is performed, the nozzle base is reciprocally moved along the core 16, and at the same time, the spindle 11 is rotated to form a coil on the core 16. The wire holding mechanism 12a is returned to its original position when the winding is started. When the winding of the coil is completed, each nozzle 13a is moved to the bobbin entwining pin 17b by the nozzle base 23a. In this state, the nozzle 13a is rotated around the pin 17b (around the Z axis) by the nozzle base, and the wire 26a is entangled with this pin. After that, the nozzle 13a is moved to the pin 22 of the wire holding mechanism by the nozzle base 23a, is rotated around this pin, and the wire is entangled with the pin 22. When the entanglement is finished, the wire holding mechanism 12a is rotated again to cut the wire between the pin 17b and the pin 22. After cutting, wire holding mechanism 12a
The nozzle base 23a moves each nozzle 13a to a position facing the pin 22 of the wire holding mechanism 12a, and is loaded on the winding machine base. Then, the pressing claw on the chuck 28 is released, the chuck rotates backward, and the nozzle base is opened.

The winding of the secondary coil is provided with a nozzle array that guides the wire for the secondary coil by rotating the spindle 11 by 180 degrees and turning it upside down, placing the binding pin of the bobbin at the position shown by the chain line in FIG. The nozzle base 23b is held by the chuck 28, and each nozzle 13b is moved to the pin 18 of the bobbin 10 to start. After the nozzle base 23b is moved to below the bobbin 10, it is raised toward the binding pin 18a.
Each nozzle 13b is rotated about the pin 18a of each bobbin by the rotational movement of the nozzle base 23b. The wire 26b is entangled with the pin 18a by this rotational movement of the nozzle. When the entanglement is finished, the wire 26b is wound around the primary coil formed in the core 16, entwined with the entanglement pin 18b, and then cut, as in the case of the winding of the primary coil. A secondary coil is formed on the primary coil. When the winding is completed, the nozzle base 23b places each of the nozzles 13b on the winding machine base at a position facing the pin 22 of the wire holding mechanism 12b,
The chuck 28 holds the nozzle base 23a again, completes one cycle of the process, and enters a standby state for the next winding. When a new bobbin is mounted on the spindle 11, each nozzle 13a
Is rotated about the entwining pin 17a by the nozzle base 23a, and the wire 26a is entangled with the pin 17a of each bobbin by this rotational movement of the nozzle, and the next winding is made.

Incidentally, the winding for the bobbin provided with the binding pin protruding from the outer surface of the flange in parallel with the central axis of the bobbin, the nozzle base 23a or 23b when binding the binding pin before and after the winding to the core. The operation of rotating the chuck 28 about the shaft 29 together with the chuck 28 only adds to the operation described above. That is, the nozzle 13a or 13b is twisted before and after the winding with respect to the core in a posture parallel to the twisting pin which is tilted 90 degrees in front of the drawing in FIG. After doing, reverse the chuck angle
To make a winding to the core in a posture perpendicular to the binding pin that is raised 90 degrees, and then to tie it to the remaining binding pin that is tilted 90 degrees to be parallel to the binding pin again. Is.

〔The invention's effect〕

As described above, the winding machine of the present invention can be wound by a plurality of nozzles that guide different types of wires by moving the nozzle base, and thus can have a compact and simple structure. Motion control can also be easily performed.
