Description

Ring-shaped Core Winding Machine [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ring-type core winding, and more particularly, to a ring-type core winding, such as a toroidal core used for a transformer or the like, Core winding.

Generally, the toroidal core, which is widely used as an inductor, is an annular core. Since a magnetic flux is formed in a closed loop and leakage magnetic flux is small, it is widely used in a high frequency circuit. In order to solve such inconvenience, a core winding machine has been proposed.

Examples of the annular core winder used to wind the coil on the annular core include an elliptical and polygonal toroidal coil winder (Patent No. 10-0639706 and No. 10-1362333) A coil winding portion for winding a coil of a wire rod on a coil core to be wound, that is, a core rotating portion for rotating and transferring the wound core in a certain step while supporting the coil core while winding the coil.

However, such a conventional coil winding machine includes a coil winding bundle 123 that is rotatably mounted on a supporting base 111, as shown by reference numeral 103 in Fig. 1, This coil winding bundle 123 is again constituted by an annular housing (not shown), a rotating ring 132 and an annular shuttle 133, as shown in Fig.

Here, although the annular housing is not shown, the coil winding bundle 123 serves as an outer body and is fixed to the opening of the support base 111 to rotatably support the rotary ring 132 As shown in Fig. 1, one side is opened so that the core C can be placed on the inner circle I of the coil winding bundle 123 of the bar. The rotating ring 132 is a kind 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 winding the coil substantially. Finally, the annular shuttle 133 is a portion where the coil is wound, coaxially fitted in the inside of the rotation ring 132, and rotates together along the rotation ring 132, but the wound coil is smoothly discharged at the time of winding So as to rotate relative to the rotary ring 132. Therefore, the coil winding bundle 123 rotates the rotating ring 132 by the rotational driving force of the driving gear 128 transmitted from the driving motor to loosen the coil wound around the shuttle 133 and rotate the core C ), Thereby completing one winding core.

In order to arrange the wound core C for the winding in the inner circle I of the annular coil winding bundle 123 as described above, one side of the rotating ring 132 and the annular shuttle 133 is formed as shown in FIGS. 2, in order to allow the rotary ring 132 and the shuttle 133 to operate normally, in the case of the rotary ring 132, as shown in FIG. 2, The opening and closing pieces 110 need to be attached to and detached from the opening portion O and the opening and closing door 120 is required for the shuttle 133. [ 2, when the core C is inserted into the coil winding bundle 123, the opening and closing pieces 110 are separated from the rotary ring 132 and the opening and closing door 120 of the shuttle 133 is closed (O) by pushing it inward so as to overlap with the opening 133 of the opening. After the core C is disposed in the inner circle I, the opening / closing piece 110 and the opening / closing door 120 are closed so that the coil winding bundle 123 can perform a normal winding operation . When the winding is finished, the opening / closing piece 110 and the opening / closing door 120 are opened again to pull out the core C disposed in the inner circle I outward.

However, as described above, in order to wind one core 123 by the conventional core winding machine 101, there is a problem that when the wound core C is placed in the inner circle I of the coil winding bundle 123, 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 and from the shuttle 133 twice when the core is collected from the inner circle I, In addition, since it takes a lot of time, the working efficiency of the coil winding is greatly reduced. Also, when the opening / closing piece 110 or the opening / closing door 120 is not tightened in order to make up for the reduced working efficiency, a large failure may occur in the entire device.

The coil winding part 21, the coil winding bundle 23, A drive bundle 25, and a lift bundle 27. [

The coil input bundle 21 is a portion into which the coil W is inserted into the coil winding bundle 23 before the winding operation is started and is extended from the one side to the coil winding bundle 23, And a coil cutter 221 mounted adjacent to the innermost putting roll 72. The feed roll 72 includes a plurality of rollers 71, . At this time, the coil cutter 221 is wound around the outer periphery of the coil winding bundle 23 so as to cut the charged end of the coil W. The coil winding bundle 23 is rotated without being constrained by the coil W So that the coil W wound on the outer periphery can be wound around the core C.

The coil winding bundle 23 is a portion which substantially coils the coil W on the core C. The coil winding bundle 23 is partly rotatably mounted on the support base 11 to release the coil W wound on the outer circumference, The winding of the coil W is repeatedly wound in accordance with the rotation of the coil winding bundle 23 so that the winding of the coil W is tightly wound on the body of the core C loaded in the winding coil I in the radial direction. To this end, the coil winding bundle 23 is formed so that the core C to be wound around the inner circle I is twisted or twisted or the core C in which the winding is completed is drawn out from the inner circle I fitted in a twisted relationship , The inner circle I is opened by one-touch operation of the user.

Thus, the coil winding bundle 23 again includes an annular housing 31, a rotating ring 32, and an annular shuttle 33, as shown in detail in Figures 3-5 and 6- do. In addition, each of the housing 31, the rotary ring 32, and the shuttle 33 has a portion 31-1, 32-1, 33-1, 32-2, 33-2 are divided in the radial direction, and the portions 31-1, 32-1, 33-1 are connected to the coil winding bundle upper portion 23-1 and the other portions 31-2, 32-2 and 33-2 form the coil winding bundle lower portion 23-2. Thus, the housing 31, the rotary ring 32, and the shuttle 33, that is, the coil winding bundle 23, are provided with a portion 31-1, 32-1, 33-1 of the same section, When the upper portion 23-1 is moved by the user's one-touch operation, the other portions 31-2, 32-2, and 33-2 are separated from the coil winding bundle lower portion 23-2, (I) is opened to allow the core (C) to be loaded or recovered.

More specifically, the coil winding bundle 23 according to the present embodiment has one end of the coil winding bundle upper portion 23-1, that is, when the inner circle I is opened, as shown in more detail in Figs. 6 and 7 And one end of the lower portion of the coil winding bundle 23-2 in the drawing, that is, one end of the coil winding bundle 23-2, . The other end, that is, the upper end, that is, the middle end, of the coil winding bundle lower portion 23-2 of the upper end of the coil winding bundle upper portion 23-1 is abutted when the inner circle I is closed, The coil winding bundle 23 is divided at an angle forming a right angle or an obtuse angle from one end of each of the upper and lower portions 23-1 and 23-2. For example, the upper and lower coil winding bundles 23-1 and 23-2 may be divided at right angles as shown in FIG. 6, but may be divided to make an angle larger than the right angle, that is, an obtuse angle. As shown in Fig. 6, when the coil winding bundle upper portion 23-1 becomes a quarter circle, and the coil winding bundle lower portion 23-2 becomes 3/4 circle when bisected at right angles.

At this time, the lower portion 23-2 of the coil winding bundle, that is, the lower housing portion 31-2, the lower portion of the rotating ring 32-2, and the lower portion 33-2 of the coil are fixed to the lower portion of the support base 11, The upper portion of the bundle 23-1, that is, the upper portion 31-1 of the housing, the upper portion of the rotating ring 32-1, and the upper portion 33-1 of the shuttle are movably mounted on the upper portion of the support 11, Although not shown, the opening of the support 11 for fitting the coil winding bundle 23 is formed to be higher than the coil winding bundle 23 so that the coil winding bundle 23 is divided into upper and lower parts as shown in FIG. 6 The coil winding bundle upper portion 23-1 may be lifted up from the coil winding bundle lower portion 23-2.

As shown in Fig. 6, the support base 11 is divided into upper and lower portions in the same manner as the coil winding bundle 23 to be formed as the upper and lower support portions 11-1 and 11-2 so as to cooperate with the coil winding bundle 23 So as to transmit an external force for lifting the coil winding bundle upper portion 23-1. The support lower portion 11-2 is fixed on the base 7 while supporting the lower housing portion 31-2, the lower rotary ring 32-2 and the lower shuttle portion 33-2, -1 is supported by the housing upper portion 31-1, the rotary ring upper portion 32-1, and the upper portion 32-1 while supporting the housing upper portion 31-1, the rotary ring upper portion 32-1, And is mated with the shuttle upper portion 33-1 on the lower support portion 11-2 so as to be movable up and down.

3 to 7, the annular housing 31 is formed in a circular opening of the support 11 so as to form an inner circle I, as shown in FIGS. 3 to 7, As shown in enlarged view in Fig. 6 so as to form a guide groove for rotatably fitting the rotary ring 32 and the annular shuttle 33, as shown in detail in Figs. 6 and 7, (35), a partition plate (36), and a finishing plate (37). At this time, the board 35 has a U-shaped cross-sectional shape so that the inner surface thereof is attached to the support base 11, and the outer tooth gear 39 of the rotary ring 32 is received in the concave groove of the outer surface. The partition plate 36 is attached to the outer surface of the substrate 35 so as to cover the recessed grooves of the substrate 35 as much as possible and serves to support the external gear 39. The finishing plate 37 supports the partition plate 36 on the substrate 35 attached to the support 11 and supports the annular shuttle 33 fitted to the rotary ring 32, And is fastened with bolts 38 onto the substrate 35 through the plate 36.

As described above, the rotary ring 32 is a portion that rotatably fits on the housing 31 and winds the coil W on the core C by rotating the rotary ring 32. As shown in Figs. 6 and 7 Similarly, the outer sheath gear 39 is formed on the inner side so as to be inserted into the concave groove of the substrate 35, and the outer sheath 41 is joined to the outer side so as to hold the shuttle 33 between the partition plate 36 and the partition plate. Therefore, the rotary ring 32 is engaged with the drive gear 28 mounted on the lower end of the support base 11 by the external gear 39, and is rotated by the rotational drive force transmitted from the drive source 29 to the drive gear 28, ).

Finally, the annular shuttle 33 is fitted in the outer periphery of the rotary ring 32 and guides the discharge of the coil W wound on the outer periphery. As shown in FIGS. 6 and 7, And is rotatable relative to the rotary ring 32 in the circumferential direction, that is, relatively rotatably mounted on the rotary ring 32. The rotary ring 32 is rotatably mounted on the housing 31, do. Further, since the coil groove 43 is formed along the outer circumferential surface, the coil W to be used for winding before the start of winding on the core C is preliminarily wound on the coil groove 43, . Therefore, the annular shuttle 33 is designed to unwind the coil W wound on the coil groove 43 during the winding operation. As the coil rotates relative to the rotation ring 32, the annular shuttle 33 gradually becomes shorter The coil W is pulled by the core C so that it can be loosened smoothly without being tense.

3 to 7, as described above, the drive ring 25 is a means for supplying a rotational driving force to the coil winding bundle 23, particularly, the rotary ring 32. As described above, A drive source 29 such as a drive motor for generating a rotational force of the drive gear 28 and a drive source 29 for driving the drive source 29 such that the rotational drive force of the drive source 29 is transmitted to the drive gear 28, And a belt pulley assembly 30 for transmitting the rotational drive force of the drive source 29 mounted in the middle of the base 7 to the drive gear 28 through the belt pulley assembly 30, (32) meshing with the drive gear (28) by means of the drive shaft (39). In this case, the drive gear 28 may further include a rotary knob 13 on the opposite side to the belt pulley assembly 30 of the gear center axis. In this case, before the drive source 29 is driven, It is possible to prepare the coil W more easily.

3 to 5, Fig. 10 and Fig. 11, the lifting bundle 27 is a means for lifting the coil winding bundle 23 by one-touch operation of the user and opening and closing the inner circle I The coil winding bundle 23 extends from the side of the coil winding bundle 23 to the position adjacent to the bottom surface through the base 7 and is again divided into the elevating guide means 57 and the elevating operation means 59.

Here, the elevation guiding means 57 is constituted by a guide rail 61 and a conveying block 62 as means for guiding the elevating operation of the coil winding bundle 23, as shown in FIG. 10, , And guide the coil winding bundle upper portion 23-1 to the lower portion 23-2 of the coil winding bundle 23-2. That is, it guides the movement of the upper support portion 11-1 which vertically moves up and down in the lower support portion 11-2. To this end, the guide rail 61 is installed adjacent to one side of the coil winding bundle 23 through a rail frame 63 provided on the base 7, as shown in Figs. 5 and 10. Therefore, the guide rails 61 are elongated up and down to guide the up and down movement of the upper portion 23-1 of the coil winding bundle, that is, the upper portion 11-1 of the support. The conveying block 62 is a means for mediating between the guide rail 61 and the coil winding bundle upper portion 23-1 or the supporting bar upper portion 11-1 as described above, Or may be indirectly attached to the support top 11-1 through an extension plate 64 as shown in Figures 5 and 10 and the rear surface may be attached to the guide rail 61 vertically And the guide block 61 and the conveying block 62 are engaged with each other by the dovetail-like concavo-convex shape, so that the guide portion of the coil winding bundle upper portion 23-1 can be more stably guided.

The elevating operation means 59 is means for moving the coil winding bundle 23, that is, the coil winding bundle upper portion 23-1 along the elevating guide means 57, A link 47, and a pivot rod 49. 3, 4, 10 and 11, the pedal 45 is installed below the base 7 so as to be pressed or released by a user. As shown in FIG. 10, The support link 46 pivots in the clockwise direction in the figure so that the push link 47 is lifted up and the coil winding bundle upper portion 23-1 and the support base upper portion 11- 1), thus opening the inner circle I. On the contrary, when the pressing force P by the user is removed, the pedal 45 returns to the original standby position by the reaction force of the return spring 65, and thus the coil winding bundle upper portion 23-1 and the support upper portion 11 -1) falls to its original closed position. The push link 47 is a rod that transmits the pushing force P applied to the pedal 45 to the pivot rod 49. The lower end of the push link 47 is connected to the support link 46) action end, and the upper end is pinned to the force end of the pivot rod (49). Therefore, the push link 47 moves up and down in accordance with the pivotal rotation of the pedal 45 to transmit the pressing force P applied to the pedal 45 to the coil winding bundle 23. Finally, the pivot rod 49 directly lifts the coil winding bundle upper portion 23-1 by the pressing force P transmitted from the pedal 45 through the push link 47 to thereby rotate the inner circle I And may be connected to the upper portion 23-1 of the coil winding bundle in various ways. For example, as shown in FIG. 10, the coil winding bundle upper portion 23-1 may be connected to the coil winding bundle upper portion (23-1). Thus, the pivot rod 49 becomes the point of force at the left end in the drawing, which is pin-coupled to the upper end of the push link 47, and passes through the extension plate 64 to the coil winding bundle upper portion 23-1, 11-1 is a point of action and the inner end on the right side in the drawing pin-coupled to the lower portion 23-2 of the coil winding bundle through the lower support 11-2 serves as a fulcrum. The pin 66 connected to the extension plate 64 is then coupled to the pivot rod 49 through the pin slot 68 so as not to constrain the pivoting movement of the pivot rod 49.
