Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic winding machine for forming a coil by winding wire around the bobbin of a matrix switch used in a communication equipment exchange, etc. When winding a wire, a coil is formed by sequentially rotating a number of bits each having a wire connection/exit around a bobbin arranged in a matrix.

In forming this coil, the rotational and feeding movements of the throat were accomplished through a single drive motor external twist gear mechanism. Therefore, if wires with different diameters are used, the gear mechanism must be replaced to accommodate the different wire diameters. In this case, it is difficult to synchronize the rotational movement and the feeding movement, making the device less versatile. Therefore, the versatility of the device is low. SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks and to provide a highly versatile automatic winding wire capable of easily synchronously controlling rotational motion and feed motion for wires of any bran diameter.

Therefore, the automatic winding machine according to the present invention includes the following: (1) to (h): (1) a bit having a wire supply outlet; a table; [d} a second table that supports the bit support base and is movable in the bobbin axis direction of the matrix switch mounted on the first table; [e' an eccentric rotation mechanism for rotating the bit; 'f} An X-direction drive pulse motor and a Y-direction drive pulse motor for causing the bit to move relative to the matrix switch in the X and Y directions in a plane parallel to the matrix switch board; (h) a rotational pulse motor for rotating the bit via the eccentric rotation mechanism; Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram showing the mechanism of an embodiment of the present invention.

A wire led from a wire spool (not shown) passes through the bit 2. The bit 2 is held on a bit support 3. A first table 27 carrying a matrix switch 8 for winding is arranged below the bit 2.
This bit support stand 3 is held on the second table 12 via an eccentric rotation mechanism 28. The second table 12 is screwed to the shaft 13 so that the bobbin 6 of the matrix switch 8 mounted on the first table 27 can be moved along the shaft 13 in the vertical direction (Z direction), that is, in the vertical direction. The shaft 13 has gear mechanisms 21, 22, 23, 24 and a close-wound clutch 1.
6 or via a coarse winding clutch 17 to the pulse motor 5 for driving in the Z direction. The eccentric D rotation mechanism 28 is composed of a shaft 9 having teeth on the outside, a shaft 10 having an eccentric hollow part that meshes with the shaft 9, and an eccentric shaft 11 inserted into the eccentric hollow part. The shaft 9 is connected to the rotating pulse motor 4 via a gear mechanism 35. Pulse motor 4 for Z direction drive
is fixed to the support frame 32. This support frame 32 is movable along an axis 33 in the left-right direction (x direction) in the figure as shown by arrow G in a plan view parallel to the matrix switch board 5. The shaft 33 is connected to the X-direction drive pulse motor 30 via a gear mechanism 36. The rotation of the shaft 33 causes the support frame 32 to slide in the direction of arrow G. The first table 27 is movable along the axis 34 in the Y direction perpendicular to the X direction (direction perpendicular to the drawing) within a plane parallel to the matrix switch board 5. The shaft 34 is connected to the Y-direction drive pulse motor 31 via a gear mechanism (not shown). The rotation of the shaft 34 causes the first table 27 to slide along the shaft 34 . Next, the operation of the automatic winding machine having the above configuration will be explained.

When tightly winding the coil, the close winding clutch 16 is operated, and the rotation of the Z-direction drive pulse motor 15 is transmitted from the shaft 18 to the shaft 19 via the gear mechanism 21 and further to the shaft 20 via the gear mechanism 23. After this, the gear mechanism 24
The shaft 13 is rotationally driven through. When the shaft 13 rotates, the second table 12 slides along the shaft 13, so that the bit 2 moves vertically along the bobbin 6 of the matrix switch 8 as shown by arrow E. When winding the coil roughly, the coarse change clutch 17 is operated and the gear mechanism 2
Rotation is transmitted by a gear mechanism 22 instead of the gear mechanism 1. At this time, the rotating pulse motor 14 is simultaneously rotated to rotate the shaft 9 via the gear mechanism 35. Therefore, eccentric shaft 1, 1
rotates eccentrically, and the bit support 3 connected to the eccentric shaft 11 similarly rotates, so the bit 2 rotates as indicated by arrow F. When the winding operation of one bobbin 6 is completed, the X direction drive pulse motor 30 is operated to move the support frame 32 in the X direction.
By moving the bit 2 in the direction, the bit 2 is moved to the next bobbin.

When the winding operation for one row is completed, the Y-direction drive pulse motor 31 is driven to move the first table 27 in the Y direction, thereby moving the bit 2 to the side of the next row to be wound.

The X and Y directions of the matrix are interchangeable, and the order of the above details may be reversed. At this time, the Z-direction driving pulse motor 15 and the rotating pulse motor 4 are simultaneously controlled on two axes according to a program set in advance using a numerical control method. Therefore, by setting a program in advance so as to give a feed amount corresponding to the length of the wire per revolution of the bit 2, both pulse motors 14 and 15 can be controlled synchronously according to the wire diameter. When using wires of different wire diameters, by changing the program it is possible to easily and accurately perform winding operations corresponding to the wire diameters. Next, the winding operation of the automatic winding machine according to the present invention will be further explained with reference to FIG.

FIG. 2 is a schematic perspective view of the matrix switch 8 mounted on the first table 27. matrix switch 8
is composed of a matrix switch board 5 and a large number of bobbins 6 arranged in a matrix on the matrix switch board 5.
Terminals 7 are installed at both ends of each bobbin row. The winding operation is performed in the following order. First, in order to fix the texture of the wire 1 to be wound, insert the bit 2 into the reference pin 4 as shown by arrow D.
to wrap the wire 1 around the reference pin 4. Next, after moving the bit 2 to the side of the terminal 7, the X direction drive pulse motor 30 and the Y direction drive pulse motor 31 (first
(Figure) alternately drives bit 2 to operate terminal 7 as in A.
The winding of the terminal 7 is performed by moving the terminal 7 around the terminal 7. At this time, if there is sufficient space around the terminal 7 for the bit 2 to rotate, the bit 2 may be rotated around the terminal 7 by a rotating pulse motor 14 (FIG. 1). Next Y
The first table 27 is moved from the outside of the directional driving pulse motor to position the first bobbin 6 to the side of the bit 2. That is, bit 2 is indicated by arrow B for matrix switch 8.
Exercise like. Next Z direction drive pulse motor 15
(Fig. 1) and the rotating pulse motor 14 (Fig. 1) are simultaneously controlled on two axes to rotate the drive bit 2 around the bobbin 6 as in operation C and move it up and down along the bobbin axis to wind the wire. Do some exercise. The moving operation as indicated by arrow B and the winding operation C are repeated to complete the winding operation of all the bobbins in one row. Next, as in operation A, after winding the bit 2 around the terminal 7, the X-direction driving pulse motor moves the bit 2 to the next column as indicated by arrow B'. Repeat this operation to complete winding on all bobbins and terminals. FIG. 3 is a schematic front view of the automatic winding machine according to the present invention.

The tension of each wire 1 is adjusted by a tension adjuster 25. As described above, the automatic winding machine according to the present invention performs the winding operation and feeding operation of the coil by driving separate pulse motors, and both pulse motors are controlled by simultaneous two-way control using a numerical control system. The rotation and feeding operations of the bit can be controlled in complete synchronization according to the wire diameter.

Additionally, wires of different diameters can be easily handled, increasing the versatility of the pupil. Further, since a large number of bits are arranged in parallel on a bit support stand, winding work can be performed on a large number of bobbins at the same time. Therefore, the uniformity of the winding state of the coil increases, the reliability of the product improves, and the efficiency of the manufacturing process increases significantly. In addition, when processing wires with different winding diameters around the terminal 7, which are small in terms of the overall processing, the eccentric movement of the bit 2 is stopped, and numerical control is used to separate the first table and the second table. This can also be done by relatively rotating them at a desired radius of rotation.
