The auxiliary main body 140 is an outer wall 141 connected to the outside of the main body 110 to surround the inlet 111 section at the outlet 112 in a state spaced apart from the transfer line 130 by a predetermined interval, And a lower bottom plate 142 between the main body 110 and the outer wall 141 and is in communication with the inlet 111 of the main body 110.

Here, the lower bottom plate 142 of the auxiliary main body 140 is a portion in which the helicoil 10, which does not stand up and is detached from the outside during the transfer through the transfer line 130, is dropped. 10 may be introduced through the inlet 111 to be re-introduced into the main body 110 and then transferred again through the spiral jaw 120.

That is, the auxiliary main body 140 of the helicoil 10 by re-injecting the helicoil 10, which is not aligned in the transfer line 130, falls into the main body 110 through the inlet 111. Enable retransmission.

The vibration generator 150 is a portion for transmitting the vibration energy in a predetermined circumferential direction to the main body 10 at a predetermined cycle so that the helicoil 10 is transferred by vibration.

The vibration generator 150 may be implemented as one selected from a vibrator (not shown) or a vibration motor (not shown) in which vibration is generated by the applied electricity, but may be replaced with another component capable of generating vibration. Of course.

The vibration generator 150 transmits the vibration generated in the direction opposite to the direction in which the helicoil 10 is transferred to the outside to the main body 110, the transmitted vibration is the inside of the main body 110 The spiral jaw 120, the transfer line 130 and the auxiliary main body 140 outside the main body 110 is also simultaneously transmitted.

Here, the helicoil 10 may be transferred in a direction opposite to the vibration direction by the inertial force to maintain the original position.

On the other hand, since the vibration of the vibration generator 150 is a vibration having a fine displacement compared to the circumferential length of the main body 110, the main body 110 may be recognized as no vibration when visual observation.

According to the vibration generator 150 as described above, the helicoil 110 can be transported and discharged at a uniform speed by transmitting a vibration of a predetermined period to the main body 110.

On the other hand, the above-described transfer line 130 is extended from the first transfer line portion 131 and the first transfer line portion 131 extending along the outer wall of the main body 110 at the outlet 112 and the inlet It may be divided into a second transfer line unit 135 extending to the outside via the (111) above.

Here, the first transfer line part 131 may also include an inclined line 132, a top plate 133 and a first bottom plate 134.

The inclined line 132 is connected to the outlet 112 and extends along the outer wall of the main body 110 in an inclined state to the outer wall of the main body 110.

The top plate 133 extends vertically at the upper end of the inclined line 132, and the first bottom plate 134 extends vertically at the lower end of the inclined line 132 and the top plate 133. Parallel to each other.

As shown in FIGS. 3A to 3C, the helical coil 10 formed to be separated from the outlet 112 is sandwiched between the top plate 133 and the first bottom plate 134 in the inclined line ( 132 is transferred to.

At this time, the interval between the top plate 133 and the first bottom plate 134 means a length corresponding to the height of the granular helicoil 10, the spacing is firmly pinched the helicoil 10. It is desirable to have a clearance such that the helicoil 10, which is already in a granular arrangement, satisfies a smooth movement that is not, and does not fall during transportation.

In addition, the helical coil 10 which is not transferred to the outside of the inclined line 132, the upper plate 133, and the first bottom plate 134 is not arranged so as to be separated from the auxiliary main body 140. After falling to the lower bottom plate 142 of the vibration generator 150 may be re-transmitted through the spiral jaw 120 while flowing back to the inlet 111 of the main body 110 by vibration.

Meanwhile, the second transfer line unit 135 may include a standing line 136 and a second bottom plate 137.

The standing line 136 is connected to the inclined line 132 and extends to the outside via the inlet 111 along the outer wall of the main body 110 in parallel with the outer wall of the main body 110.

In addition, the second bottom plate 137 vertically extends from the lower end of the standing line 136 to be connected to one end of the first bottom plate 134, and the tang of the helical coil 10 in the longitudinal direction. A tang groove 138 on which the 11 is seated is formed.

Here, in the helical coil 10 which is transported in a standing state between the top plate 133 and the first bottom plate 134 of the first transfer line unit 131, the tang 11 is disposed below There may be two cases in which the conveying or the tang 11 is disposed upward and conveyed.

The helicoil 10, in which the tang 11, which is the former case, is disposed below and is transported, enters the second bottom plate while entering the second transfer line unit 135 from the first transfer line unit 131. As the tang 11 is seated in the tang groove 138 formed at 137, the tang 11 is transported in a standing state.

On the contrary, in the latter case, the helicoil 10, in which the tang 11 is disposed upward and is transferred, does not maintain the standing state as it enters the second transfer line unit 135 from the first transfer line unit 131. After falling off to the outside, the auxiliary body 140 is dropped. Here, the dropped helicoil 10 may be re-injected back to the inlet 111 of the main body 110 and then re-transmitted through the spiral jaw 120.

Meanwhile, as the inclined line 132 of the first transfer line part 131 moves away from the outlet 112 as shown in FIG. 3B or 3C, the inclination angle of the inclined line on the outer wall of the main body 110 decreases. After the connection to the standing line 136 can be seen that parallel to the outer wall of the main body 110.

Therefore, the helical coil 10 is transferred to the inclined state through the inclination line 132 of the first transfer line part 131 at the initial departure from the outlet 112, and gradually decreases after the inclination is relaxed. As it enters the standing line 136 of the second transfer line unit 135, it may naturally stand vertically.

On the other hand, as shown in Figure 3b or 3c, the second bottom plate to the longitudinal direction extending outward from the portion corresponding to the upper portion of the inlet 111 with respect to the longitudinal direction of the standing line 136. It is further provided with a departure prevention jaw 139 perpendicular to the standing line 136 is installed vertically to 137, to prevent the helicoil 10 is transported in the standing state to the outside.

On the other hand, the coil standing means 100 may be further provided with an outer case 160 surrounding and protecting the main body 110, the auxiliary main body 140, the vibration generator 150, the upper portion of the case 160 Casement cover (not shown) may be further provided.

In addition, a through hole 161 is formed in the case 160 to extend in a state where the transfer line 130 penetrates to the outside of the case 160, so that the transfer line 130 is erected and transferred through the transfer line 130. The helicoil 10 is to be smoothly transferred to the coil insertion means 200 is disposed separately to the outside.

The helical coil 10 transferred in the above manner may be inserted into the screw hole 21 of the component 20 through the coil inserting means 200.

According to the coil erecting means 100 as described above, since the helicoil 10 is automatically erected and transferred to the coil inserting means 200 before the helicoil insertion process, the hassle of the conventional erecting arrangement by manual labor is eliminated. As it can be solved, the convenience of the operation is improved, as well as the waste of manpower is reduced and the insertion process of the helicoil 10 is facilitated, so that the productivity of the part 20 into which the helicoil is inserted can be improved.

The coil erecting means 100 is not limited to the illustrated form, and may be modified and replaced in another form to erect the helical coil 10 to be transferred to the coil inserting means 200.
