Abstract

PURPOSE:To obtain the diversity in operation of a wire holder by cutting a crossover wire between the wire holder and coil terminal to draw out and to remove wire material wastes entangling around the wire holder. CONSTITUTION:A wire holder 10 around which a starting end of a wire material 1 fed from a wire guide nozzle 5 is entangled is rotated with a coil terminal as a center to twine the linear material around the coil terminal with rotation of the wire guide nozzle. After that, a crossing wire between a coil terminal and the wire holder 10 is cut by rotation of the wire holder 10. Next, the wire holder 10 is lowered and is sunk in an exhaust sleeve 32 to draw out and remove linear material wastes twining on the wire holder 10. After winding on a bobbin body by rotation of the bobbin, said wire holder is moved to the side of another coil terminal and the similar winding process is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of winding wire onto a bobbin in an automatic winding machine, and in particular, it facilitates attaching a wire to a coil terminal and cutting a crossover wire between a coil terminal and a wire holder. In addition to being able to easily extract and remove wire scraps that are stuck to the wire holder, automatic firing can improve the range of applicable functions and reduce the space occupied around the bobbin. This relates to a method of winding a bobbin in an lfM machine.

In recent years, intermediate frequency transformers, various transformer exposure relays, etc.
In R-making, a winding machine has been proposed that can automatically perform not only winding the bobbin body but also tying the wire to the coil terminal as a series of operations. However, conventional automatic winding machines sometimes have to move the wire holder when winding the bobbin body or attaching the wire to the coil terminal. Since this method uses the proximal end of the wire holder as a fulcrum and swings the tip of the wire holder, the movement of the wire holder is restricted due to the mechanism that drives the wire holder, and the length of the crossover wire is short (sometimes it is difficult to do so). In addition, the method for extracting and removing the wire layer stuck to the wire holder is such that winding the wire onto the bobbin body and attaching the wire to the coil terminal are carried out in the same plane as the operation. When winding the wire on the bobbin body or attaching the wire to the coil terminal, the wire layer may be inadvertently mixed in during operation, resulting in defective products, and there is room for improvement in terms of the appearance of the machine. There were various problems such as what seemed to be the case.

Therefore, the present invention was made in view of the above circumstances, and aims to facilitate the winding of the wire onto the bobbin body and the attachment of the wire to the coil terminal, as well as the ease of extracting and removing the wire layer from the wire holder. It is possible to prevent the wire layer from accidentally getting into the bobbin or various drive mechanisms during the winding operation of the coil on the bobbin, and to move the wire holder to a position that conforms to the coil winding specifications. An object of the present invention is to provide a method for winding a bobbin in an automatic winding machine, which can be expected to reduce the space occupied by the entire device around the bobbin.

In order to achieve the above-mentioned object, the present invention is an automatic winding machine that winds the body of a bobbin and wraps the wire rods that are to become the starting and ending ends of the winding around the coil terminals of the bobbin. The wire holder to which the starting end of the wire to be attached is attached is moved to the side of one coil terminal, and the wire guide nozzle rotates around the coil terminal to attach the wire to the coil terminal. After attaching, the crossover wire between the coil terminal and the wire holder is cut by rotating the wire holder, and then the wire holder is lowered and immersed in the discharge sleeve to remove the wire layer stuck to the wire holder. After the wire is removed and the bobbin is rotated to wind the bobbin body, the wire holder is moved to the side of the other coil terminal, and the wire guide nozzle rotates around the other coil terminal. Then, attach the wire that will become the end of the coil to the other coil terminal, and then the wire guide nozzle rotates around the wire holder to wrap the wire around the wire holder, and then attach the wire to the other coil terminal. This method is characterized by a method of winding a bobbin in an automatic winding machine, in which a connecting wire between the wire and the wire holder is cut by rotation of the wire holder, and the process is repeated every time the bobbin is wound thereafter.

For mounting, a bearing 17°17 is interposed on the board 11, and the support plate for the wire holder]8 is mounted on the board 11.
The base end of the second air cylinder J9 is attached to the base plate 11, and the piston rod 19a of the second air cylinder J9 is attached to the support plate 18. They are connected so that the support plate 18 can be moved in the left-right direction by the second air cylinder J9. The range of movement in the left and right direction can be adjusted by turning the screw 34 screwed onto the mounting board J. That is, it is adjusted by the abutment position of the support plate J8 against the tip of the screw 34. A storage case 20 for accommodating each wire holder 10 is provided on the support plate 18 so as to be movable up and down guided by guide rods 21.degree. 21 fixed to both ends of the support plate 190.

A contact plate 28 is provided inside the storage case 20. The abutting plate 28 is loosely fitted into a guide bin 50.50 installed in the storage case 20, and can freely come into contact with a discharge operation plate 28a fixed to the support plate 18 via an engagement plate 28b. Although the wire holders 10 are movable back and forth and left and right together with the storage case 20, they do not move up and down together with the storage case 20 when they come into contact with the ejection operation plate 28a via the engagement plate 28b, and each wire holder 10 does not move up and down. A hole 29 is bored into which the hole 29 is movably inserted. On the other hand, a discharge sleeve 32 is fitted into each wire holder IO so as to be engaged at a position slightly below the distal end thereof and to be movable up and down relative to the distal end of the wire holder IO above the interlocking stepped portion 31.

Each wire holder 10 is shown in FIGS.
As shown in FIGS. 13 to 13, the tip part is an engaging part 33 of the wire rod 1 formed into a substantially rectangular shape with a thousand sides and having the same curvature as the other parts.

Each wire guide nozzle 5 is fixed to a rotating shaft 6.

The rotating shaft 6 is rotatably supported by drive columns 7, and a binion gear 35 provided at one end of the rotating shaft 6 is meshed with a rack 36 movably supported within the drive column 7. Each wire guide nozzle 5 is designed to be able to rotate 90 degrees with its tip held at the same position, that is, with its tip as the center. The rank 36 is driven by an air cylinder. On the other hand, the driving columns 7, 7 can be moved back and forth together with each wire guide nozzle 5 by a back and forth movement device 37 that is a combination of a servo motor and a ball screw, and can be moved left and right by a device that is not shown in the drawings and is a servo motor and a ball screw. It can be moved up and down.

First, each bobbin 38 is fitted into each bobbin holder 8 in the front row shown in FIG. .

As described above (if the rotary support body 9 is rotated 180 degrees, the bobbin holder 8 on which the bobbin 38 is not fitted will be located on the front side, and the bobbin 38 will be fitted on the bobbin holder 8 for the next winding. Be prepared (.

Next, since the winding operation is the same for each bobbin 38, one bobbin 38 will be described. First, as shown in FIG. 4, the wire 1 fed out from the wire guide nozzle 5 is wound around the tip of the wire holder 10.
The wire holder 10 is shown in FIGS. 4 and 14 (
The bobbin 38 is moved to the side of one coil terminal 38a (position P in FIG. 4). This movement is performed by driving the first air cylinder 12.

Next, the wire guide nozzle 5 is rotated 90 degrees around the tip, and after positioning the wire guide nozzle 5 in the longitudinal direction of the coil terminal 38a, the wire guide nozzle 5 is moved vertically and Coil terminal 3 is activated by combining the left and right movements.
The wire guide nozzle 5 is rotated in a circular trajectory around the center 8a to wind the wire l, which is to become the starting end of the coil, around the coil terminal 38a, and the wire guide nozzle 5 is gradually The wire 1 is neatly wound in a coil shape around the coil terminal 38a by moving the wire holder JO backward and forward as shown in FIG. The cylinder 26 is driven to rotate the wire holder] 0 and the coil terminal 3 through the rack 25 and pinion gear 24.
Cut the crossover wire Ja between it and 8a. The cutting point is the crossover wire la from the wire holder JO to the coil terminal 38a.
Since the cylindrical portion 10a of the wire holder 10 has a larger diameter than the coil terminal 38a and the coil terminal 38a has a rectangular cross section, it is cut at the corner of the coil terminal 38a. Even if the cross-sectional shape of the coil terminal 38a is circular, cutting conditions can be improved by increasing the diameter of the cylindrical portion JOB (and adjusting the distance between the bobbin 38 and the wire holder 10). As shown in the figure, the storage case 20, that is, the wire holder 10 is lowered by the drive of the third air cylinder 22, and the discharge sleeve 3 is lowered.
2 comes into contact with the contact plate 28, and the wire holder IO
enters the discharge sleeve 32, and as a result, the cut wire layer 16 wound around the tip of the wire holder 10 is pushed out and extracted from the wire holder 10 by the discharge sleeve 32. It falls into the hopper below,
collected. After drawing out and removing the wire layer 16, the wire holder 10 remains in the lowered state, and the second air cylinder 19 is used to open the other coil terminal 38b (m) as shown in FIGS. 9 and 14. Q, (D position) After moving K, the wire holder 10 moves to the third air cylinder 2.
2, and as the discharge sleeve 32 rises, the discharge sleeve 32 descends to the locking step 3 and locks therein. On the other hand, the wire guide nozzle 5 is rotated 90 degrees to be in an upright state, and is moved forward to above the body 38C of the bobbin 38 by the drive of the back-and-forth movement device 37, as shown by arrow C in FIG. 8, the winding IC is applied by the preset number of turns. During the winding operation on the body 38c of the bobbin 38, the wire guide nozzle 5 moves forward and backward in a scanning manner by the drive of the forward and backward movement device 37. Of course, it is possible to wind the wire neatly into a coil shape.
After moving the wire guide nozzle 5 to the vicinity above the other coil terminal 38a as shown in FIG. 10 by the motion of the front-back, up-down, and left-right operating device, the wire guide nozzle 5 is rotated 90 degrees in the same manner as described above. Then, the wire guide nozzle 5 is positioned in the longitudinal direction of the other coil terminal 38b, and the wire guide nozzle 5 is rotated about the other coil terminal 38b, so that the end of the coil is connected to the coil terminal 38b. Attach the wire J to be used.Next, the 11th
As shown in the figure, after rotating the wire guide nozzle 5 90 degrees around the tip and standing it upright, the wire holder 1
Move it to near 0. Needless to say, the coughing movement is performed by moving the driving columns 7, 7 by combining the motions of the front-back, up-down, and left-right motion devices as described above. Furthermore, the first
As shown in FIG. 2, the wire guide nozzle 5 is again rotated around the wire holder JO by driving each of the longitudinal, vertical, and horizontal movement devices to sprinkle the wire 1 onto the wire holder 10. The winding method is to first wrap it around the cylindrical part below the engagement part 32 several times, and then wrap it around the engagement part 32 several times. As a result, by maintaining a strong engagement with the wire 1 at the engagement portion 32 and wrapping it around the cylindrical portion, it is possible to prevent the crossover wire 1d from being accidentally cut near the wire holder 10. Next, as shown in FIG. 13, the wire holder 10 is rotated in the same manner as described above.
The crossover wire 1d between the wire holder 10 and the coil terminal 38b is cut near the coil terminal 38b. At this time,
In this state, the wire 1 between the wire guide nozzle 5 and the wire holder JO is not cut, and the wire holder 10 is moved to the first air cylinder J2 as shown in FIG.
After retracting to the R position by driving the second air cylinder J9, move it to the 8th position with the drive 11 of the second air cylinder J9 to prepare for the next winding. On the other hand, in the case of the wound bobbin 38, the rotating support 9 rotates by 90 degrees in the direction shown by the arrow B in FIG.
After the bobbin is inserted into the notch groove 41 and winding is completed, the bobbin is extracted from the bobbin holder 8 and falls onto a hopper (not shown). Furthermore, after the bobbin extraction operation, the rotary support body 9 rotates the remaining 90 degrees to complete the series of operations. Before the rotating support 9 is rotated 180 degrees, the bobbin 38 to be wound next is installed in advance on the bobbin holder 8 located on the front side, so that the one-turn support 9
When the rotation plate rotates 180 degrees, the coil terminal asa, 38b is located near the wire guide nozzle 5, and the above-mentioned binding of the coil terminal asa, 38b is performed, and the winding operation of the bobbin 38 to the body 538C is performed. The body 9 is repeated every 180 degrees of rotation of the plate. Each of the above operations is controlled by a microcomputer.

FIG. 15 shows another embodiment in which each coil terminal 38a', 38b' of a bobbin 381 is formed in an upright state perpendicular to the axis of the bobbin 38'.

Also when attaching the wire rods 11 that will become the starting and ending ends of the coil to the coil terminals 38a' and 38b'.

The wire guide nozzle 5 does not have to be rotated by 90 degrees (it can be done in an upright position), but the rest is exactly the same as the previous embodiment.

As described above, according to the method for winding a bobbin in the automatic winding 1a according to the present invention, by simply rotating the wire holder, the crossover wire between the wire holder and the coil terminal can be cut, and the wire holder can be moved into the ejection sleeve. It is inserted into the wire holder and attached to the wire holder (the wire layer is extracted and removed), so the wire holder can be operated in a variety of ways, easily adapting to changes in the shape of the coil, and reducing the space around the coil. can be used effectively, and has great effects such as not only simplifying the process of attaching the wire to the coil terminal but also making it easy to cut the connecting wire between the coil terminal and the wire holder.
