Description

Ring-shaped Core Winding Machine

The present invention relates to an annular core winding machine, and more particularly, to semi-automatically transversely winding a wire coil on the body of an annular core such as a toroidal core used in a transformer, that is, an annular winding used for radial winding. It relates to a core winding machine.

In general, the toroidal core, which is widely used as an inductor, is an annular core and is widely used in high-frequency circuits because the magnetic path constitutes a closed circuit and thus has a low leakage magnetic flux. And, in order to solve this inconvenience, a core winding machine has been proposed.

As an example of an annular core winding machine used to wind a coil around an annular core as described above, there may be mentioned a'oval and polygonal toroidal coil winding machine' (Registration Patent Nos. 10-0639706 and 10-1362333). This coil winding machine It consists of an annular core to be wound, that is, a coil winding unit that winds a coil of a wire rod around a core to be wound, and a core rotating unit that rotates and transfers the core to be wound in a predetermined step while supporting the core while winding the coil.

However, such a conventional coil winding machine includes a coil winding bundle 123 in which a coil winding unit for winding a coil around a core C is rotatably mounted on a support 111, as shown by reference numeral 103 in FIG. 1. Bar, this coil winding bundle 123 again, as shown in Figure 2, is composed of an annular housing (not shown), a rotating ring 132 and an annular shuttle 133.

Here, although the annular housing is not shown, the coil winding bundle 123 is a part forming the outer body, and is fixed to the opening of the support 111, and serves to support the rotating ring 132 so as to be rotatable. As shown in Fig. 1, one side is opened so that the core (C) can be disposed in the inner circle (I) of the bar and coil winding bundle 123. In addition, the rotating ring 132 is a type of ring gear, which is engaged with the driving gear 128 connected to the driving motor and rotates by the rotational driving force transmitted from the driving motor, thereby substantially winding the coil. Finally, the annular shuttle 133 is a part where the coil is wound, and is coaxially fitted inside the rotation ring 132, and rotates together along the rotation ring 132, but the wound coil is smoothly discharged when winding. It is designed to rotate relative to the rotation ring 132 so that it can be. Accordingly, the coil winding bundle 123 rotates by the rotational driving force of the driving gear 128 transmitted from the driving motor to release the coil wound around the shuttle 133 and the core (C) disposed in the loading position. ) To complete one winding core.

However, in order to arrange the core (C) to be wound for winding in the inner circle (I) of the annular coil winding bundle 123 as above, one side of the rotary ring 132 and the annular shuttle 133 is shown in Figs. As shown in Fig. 2, an opening (O) must be formed. In order to allow the rotation ring 132 and the shuttle 133 to operate normally, in the case of the rotation ring 132 as shown in FIG. An opening and closing piece 110 that is detachable from the opening O is required, and in the case of the shuttle 133, an opening and closing door 120 is required. Therefore, when inserting the core (C) into the coil winding bundle 123, as shown in Figure 2, separating the opening and closing piece 110 from the rotary ring 132, and shuttle the opening and closing door 120 of the shuttle 133 Open the opening (O) by pushing it in so that it overlaps with (133). After arranging the core (C) in the inner circle (I), as shown by a hidden line in Fig. 2, the opening and closing piece 110 and the opening and closing door 120 are closed so that the coil winding bundle 123 can perform a normal winding operation. To be. When the winding is finished, the opening and closing piece 110 and the opening and closing door 120 are reopened to take out the core (C) disposed in the inner circle (I).

However, as above, in order to wind one core 123 by the conventional core winding machine 101, when the core to be wound (C) is disposed in the inner circle (I) of the coil winding bundle 123, the winding When the core is collected from the inner source (I), it is necessary to attach and detach the opening and closing piece 110 to the rotary ring 132 and the opening and closing door 120 to the shuttle 133, which is very cumbersome. In addition, since it takes a lot of time, there is a problem that the work efficiency of the coil winding is greatly reduced. In addition, there is a problem in that a major failure may occur in the entire device when the fastening of the opening and closing piece 110 or the opening and closing door 120 is neglected in order to compensate for the reduced work efficiency.

Even without, it is possible to lift the upper half of the coil winding bundle 23-1 upward from the lower half of the coil winding bundle 23-2.

At this time, as shown in FIG. 6, the support 11 is divided up and down in half like the coil winding bundle 23 to form the upper and lower halves 11-1 and 11-2 of the support, so that together with the coil winding bundle 23 It is desirable to transmit an external force that lifts the upper half of the coil winding bundle 23-1 while moving. Accordingly, the support lower half 11-2 is fixed on the base 7 while supporting the housing lower half 31-2, the rotary ring lower half 32-2, and the shuttle lower half 33-2, and the support upper half 11 -1) is a housing upper half 31-1, a rotary ring upper half 32-1, and a shuttle upper half 33-1 while supporting the upper half of the housing 31-1, the upper half of the rotary ring 32-1, and It is matched on the lower half of the support (11-2) so as to be movable up and down together with the upper half of the shuttle (33-1).

On the other hand, the annular housing 31 is a part constituting the outer body of the coil winding bundle 23, as shown in Figs. 3 to 7, in the circular opening of the support 11 so as to form an inner circle (I). As shown enlarged in FIG. 6 to form a guide groove for rotatably inserting the rotating ring 32 and the annular shuttle 33, as shown in detail in FIGS. 6 and 7, the substrate It consists of (35), a partition plate (36), and a closing plate (37). At this time, the substrate 35 has a U-shaped cross-sectional shape, so that the inner surface is attached to the support 11 and the outer gear 39 of the rotary ring 32 is accommodated in the concave groove on the outer surface. In addition, the partition plate 36 is attached to the outer surface of the substrate 35 so as to block the concave grooves of the substrate 35 as much as possible to support the external gear 39. Finally, the closing plate 37 supports the partition plate 36 on the substrate 35 attached to the support 11 and at the same time supports the annular shuttle 33 fitted in the rotary ring 32. It is fastened with bolts 38 on the substrate 35 through the plate 36.

In addition, as mentioned above, the rotary ring 32 is a portion that is rotatably fitted on the housing 31 to rotate the coil W around the core C. As shown in FIGS. 6 and 7 Likewise, the outer gear 39 is formed on the inside so as to be inserted into the concave groove of the substrate 35 and rotated, and the outer plate 41 is coupled to the outside so as to sandwich the shuttle 33 between the partition plate 36 and to support it. Therefore, the rotary ring 32 is engaged with the drive gear 28 mounted on the lower end of the support 11, the external gear 39, and the housing 31 by the rotational driving force transmitted from the drive source 29 to the drive gear 28. ) To rotate along.

Finally, the annular shuttle 33 is a means for guiding the discharge of the coil W that is fitted to the outer periphery of the rotary ring 32 and wound around the outer periphery, as shown in FIGS. 6 and 7, the rotary ring 32 It is inserted into the concave groove formed between the end plate 37 and rotates along the housing 31 together with the rotary ring 32, but is mounted to enable relative movement, that is, relative rotation in the circumferential direction with respect to the rotary ring 32 do. In addition, since the coil groove 43 is formed along the outer circumferential surface, the coil (W) to be used for winding is pre-wound in the coil groove 43 before starting the winding for the core (C), that is, to be prepared by winding in advance. Has been. Therefore, the annular shuttle 33 is designed to unwind the coil W wound around the coil groove 43 during the winding operation, and by rotating relative to the rotary ring 32, the coil becomes shorter as it is wound around the core (C). The coil (W) is pulled by the core (C) so that it can be smoothly released without tension.

On the other hand, the drive bundle 25 is a means for supplying rotational driving force to the coil winding bundle 23, in particular, the rotary ring 32, as mentioned above, as shown in Figs. 3 to 7, the rotary ring ( 32), the drive gear 28 mounted in the support 11 so as to be engaged with the drive gear 28, a drive source 29 such as a drive motor that generates the rotational force of the drive gear 28, and the rotational driving force of the drive source 29. It consists of a belt pulley assembly 30 that transmits to 28, and transmits the rotational driving force of the driving source 29 mounted in the middle of the base 7 to the driving gear 28 through the belt pulley assembly 30, The rotation ring 32 engaged with the drive gear 28 is rotated by (39). At this time, the drive gear 28 may further include a rotation handle 13 on the opposite side of the belt pulley assembly 30 of the gear center axis, in this case, before driving the drive source 29, that is, before the winding starts, the rotation handle 13 ) Through the rotation ring 32, it is possible to more easily wind the coil (W) around the outer periphery of the shuttle (33).

Finally, the lifting bundle 27 is a means for the coil winding bundle 23 to be raised and lowered by the user's one-touch operation to open and close the inner circle I, as shown in FIGS. 3 to 5, FIG. 10 and FIG. As described above, the coil winding bundle 23 penetrates the base 7 from one side and extends to a position adjacent to the floor, and is further divided into an elevating guide means 57 and an elevating operation means 59.

Here, first, the elevating guide means 57 is a means for guiding the elevating operation of the coil winding bundle 23, and is again composed of a guide rail 61 and a transfer block 62, as shown in FIG. , Guide the lifting of the upper half of the coil winding bundle (23-1) to the lower half of the coil winding bundle (23-2). In other words, it guides the movement of the upper half of the support (11-1) that moves up and down from the lower half of the support (11-2). To this end, the guide rail 61 is installed adjacent to one side of the coil winding bundle 23 through the rail frame 63 installed on the base 7 as shown in FIGS. 5 and 10. Accordingly, the guide rail 61 is elongated vertically to guide the lifting of the upper half of the coil winding bundle 23-1, that is, the upper half of the support 11-1. In addition, the transfer block 62 is a means for mediating the guide rail 61 and the upper half of the coil winding bundle (23-1) or the upper half of the support (11-1), the front of which is the upper half of the coil winding bundle (23-1). ), or as shown in Figs. 5 and 10, can be indirectly attached to the upper half of the support 11-1 through the extension plate 64, and the rear can be moved up and down on the guide rail 61 The transfer block 62 and the guide rail 61 are fitted together so that the guide of the upper half 23-1 of the coil winding bundle can be more stably engaged by being engaged with the dovetail-shaped irregularities.

The core rotation unit 5 is a means for holding the core C when winding the coil W around the core C by the coil winding unit 3 as described above, and the core C, which is a winding object, is loaded at the loading position L ), but also serves to rotate the core (C) seated in the loading position (L) at a certain angle by interlocking with the rotation of the coil winding unit 3, in particular, the rotary ring 32. That is, when the rotating ring 32 rotates once to wind the coil (W) around the core (C) one rotation, the coil (W) can be wound by the next one. For example, while the rotary ring 32 in FIG. 13 rotates one rotation in the direction of the arrow B, the core C is rotated one feed in the direction of the arrow C, so that the coil W can be wound with the next wheel.

To this end, the core rotating unit 5 includes a roller bundle 75 supporting the core C in the loading position L and the roller bundle as shown in FIGS. 3 to 5, 8, and 9 It consists of a transfer bed (77) for moving 75) up and down and back and forth.

Here, the roller bundle 75 is again a drive roll 79 that directly feeds and rotates the core C, and a plurality of support rolls 81 that support the core C before and after the drive roll 79 As shown in FIG. 9, the drive roll 79 is rotated by a step motor 82 connected to the lower end to move the core C and rotate each support roll 81 ) Is contacted or separated from the core C by the rotation of the opening/closing handle 83 linked through the worm 84 and the worm gear 85. In particular, the driving roll 79 is pressed to the core (C) through the pressure assembly 86 assembled at the bottom, as shown in FIG. 8, the position where the pressure rod 87 is coupled by the pin 89 It is possible to adjust the pressing force on the core (C) by changing or by changing the coupling position of the pin 90 of the spring clasp 88 to the pressing rod 87. In addition, each of the support rolls 81 is synchronously rotated with the driving roll 79 by a rotational force transmitted through the gear train 93 connected before and after the driving roll 79.

In addition, the moving bed 77 can change the position of the roller bundle 75 as desired by adjusting the height of the bed surface or the separation distance from the core (C) by the upper and lower adjustment units 91 and the left and right adjustment units 92, This can be implemented by various known means. In this embodiment, as shown in FIG. 8, the upper and lower adjustment unit 91 is composed of an adjustment handle 93, a bevel gear row 95, and a transfer screw 97. , The left and right adjustment units 92 are composed of an adjustment handle 94 and a transfer screw 96.

Now, the operation of the annular core winding machine 1 according to a preferred embodiment of the present invention will be described as follows.

In order to wind the coil (W) on the core (C) by the core winding machine (1) of the present invention, first, as a preparation process, as shown in FIG. 6, by stepping on the pedal (45) to operate the lifting bundle (27) The upper half (23-1) of the coil winding bundle of the part (3) is lifted up together with the upper half of the support (11-1). Accordingly, when the inner circle (I) of the coil winding bundle 23 is opened, the core (C) to be wound is inserted into the inner circle (I) through the opening as shown in FIG. It is positioned on the inner circle (I) so that when the inner circle (I) is closed as shown in FIG. 3, the core (C) is arranged in a twisted relationship with the coil winding bundle (23).

Then, the coil W input through the coil input bundle 21 from the external winding coil is wound around the outer periphery of the coil winding bundle 23. To this end, as shown in FIG. 12, the coil (W) received from the outside along the input roll 72 is passed through the coil cutter 221 and fixed to the shuttle 33 of the coil winding bundle 23, and then the drive source ( 29) is rotated in the reverse direction to rotate the rotary ring 32 in the direction of the arrow (A) of FIG. 12. Accordingly, the coil (W) supplied from the outside along the input roll (72) is wound in the coil groove (43) of the shuttle (33), for example, 200 times as much as the amount used to wind one core (C). It is wound around the degree shuttle 33. At this time, the number of rotations of the rotation ring 32 is counted by the rotation detection sensor 51 and is controlled by the control unit. In this way, when the coil (W) is wound by a predetermined length, the operator cuts the coil (W) by turning the cutting knife 225 of the coil cutter 221, and, as shown in FIG. 13, the cut end is a coil cutter. After being inserted into the coil hanger 53 on the upper end of the housing 31 adjacent to the 221, it is hooked on the guide roll 55 to finish the storage of the coil W.

However, before or after preparing the coil (W) as above, a bar to seat the core (C) inserted in the inner circle (I) in the loading position (L), FIGS. 3 to 5, 8, and As shown in FIG. 9, the core (C) is seated on the core rotating part (5). To this end, the operator first operates the opening/closing handle 83 to open the front and rear support rolls 81 back and forth, and then pull out the pin 90 of the spring clasp 88 to disassemble the pressure assembly 86. Then, the core C is placed on the triangular support points formed by the two support rolls 81 and the drive rolls 79. Next, as shown in Figs. 8 and 9, after the support roll 81 is in close contact with the core (C), the spring clasp 88 is again hooked to the pressure rod 87, and the driving roll 79 is also a core ( C) pressed. At this time, since the position of the drive roll 79 can be changed by changing the coupling position of the pin 89 according to the diameter of the core C, it is possible to appropriately cope with the change in the diameter of the core C. In this way, after seating the core (C) between the three rolls (79, 81), by operating the handles (93, 94) of the vertical adjustment unit 91 and the left and right adjustment unit 92, the vertical height of the transfer bed 77 By adjusting the position, the loading of the core (C) is finished. Adjusting the height of the transfer bed 77 in this way is to align the height of the winding with the center of the coil winding bundle 23, that is, the inner circle I, at the loading position (L) that changes according to the thickness of the core (C). And, aligning the left and right positions of the transfer bed 77 means that even when the diameter of the core (C) changes greatly, the position where the winding is made at the loading position (L) is at the center of the coil winding bundle (23), that is, the inner circle (I). It is to make it come.

In this way, when the loading of the core (C) and the receiving of the coil (W) are completed, the coil (W) which was hung on the guide roll 55 is pulled and fixed by winding it once on the core (C) body as shown in FIG. After that, the drive source 29 is started in the forward direction to rotate the rotary ring 32 in the direction of the arrow B, so that the coil W wound around the shuttle 33 is wound around the core C. At this time, as mentioned above, when the rotating ring 32 rotates 1, the core (C) rotates 1 feed in the direction of the arrow (C), and the coil (W) is rotated the next time the rotating ring 32 rotates. Try to wind it on the pitch. When the rotating ring 32 is rotated a predetermined number of times as described above, for example, the coil (W) is wound on the core (C) about 1000 times, and all the coils (W) wound on the shuttle (33) are transferred to the core (C) and wound. The winding of the core (C) is completed.

Finally, the winding core (C) of the loading position (L) is separated from the core rotating part (5), and the inner circle (I) is opened again by stepping on the pedal (45) to lift the upper half (23-1) of the coil winding bundle. After that, when the winding core C separated at the loading position L is collected from the coil winding unit 3, the core winding operation is completed.
