Abstract

The invention provide a transfer mechanism for a formed lead wire capable of easily performing the forming of a lead wire and transfer to a rotating drum without requiring auxiliary materials such as paper tape. When a straight lead wire 4 is fed to a forming die 4, a cutting guide 7 cuts the lead wire 4 to a predetermined length, thereafter, a pusher 6 pushes the central part of this lead wire in a horizontal direction and pushes it out from an opening 3 of the forming die, and then the lead wire is formed to an U-shape. A U-shaped lead wire pushed out by the pusher 6 is held in an inward groove 10 of a holder 9 by its spring force. When the holder 9 descends, both the end portions of the U-shaped lead wire are bent inwardly by a guide face 13a of a holding tooth 13 of the rotating drum 11, moreover, the holder 9 is raised in a state where the lead wire is fitted to a fitting face of the lead wire, and the lead wire can be transferred from the holder 9 to the holding tooth 13.

Description

The transfer device of formed lead

The present invention relates to the transfer device of formed lead, in detail, relate to the lead-in wire that is shaped to the U font is transferred to mechanism on the going barrel.

At (a) of installation diagram 1 automatically with during this pearl inductor (PVC-Block ィ Application ダ Network ) (b), at first the lead-in wire that is shaped to the U font is vacated certain interval and remain on the delivery medium such as paper tape with holes, deliver discontinuously.Send into the going barrel that rotates with certain speed delivering medium from its wiring direction, and the peripheral speed of going barrel and the speed of sending into of medium are kept synchronously, will make thus and on the periphery of going barrel, form of the transfer of maintenance lead-in wire in the media to the maintenance tooth.The lead-in wire that has carried out shifting on going barrel is inserted in the pearl shape inductor that remains on the going barrel, then, and with the band colligation.

But, in above-mentioned this transfer device, after making lead-in wire be shaped to the U font, in order to be carried to it on going barrel at certain intervals, just need to use medium such as paper tape with holes, but because these medium can not produce other surcharge, and become the reason that cost rises.And need be used to make medium to keep synchronously and the mechanism that sends into, and extracting lead-in wire and transferring on the maintenance tooth of going barrel from medium on the going barrel with going barrel.

Therefore, the purpose of this invention is to provide a kind of transfer device of formed lead, do not need auxiliary material such as paper tape, just moulding that can go between simply and lead-in wire are to the transfer of going barrel.

To achieve these goals, the transfer device of formed lead of the present invention comprises: the forming metal film, supply with straight lead-in wire; Propeller can be arranged in the molding metal mold with moving horizontally, pushes down straight lead-in wire central portion in the horizontal direction and extrudes from the peristome of molding metal mold, making lead-in wire be shaped to the U font thus; Support can be configured in angle of rake front portion up or down, has both ends interior to groove that keeps the U font lead-in wire that extruded by propeller by its elasticity; Going barrel, has the maintenance tooth, it has and can be arranged on the below of support rotatably with the center of trunnion axis and constitute to the inside the spigot surface that tilts to constituting the lateral surface at the both ends of lead-in wire being remained on buckling surface on the bottom of spigot surface, the interior interval to groove that is narrower than above-mentioned support is set at the interval of above-mentioned buckling surface for, when support descends, slide and bending to the inside along spigot surface in the both ends of the lead-in wire in remaining in groove, under the state of lead-in wire insertion buckling surface, support is risen, thus, going between from changing-over on the support to keeping on the tooth.

When straight lead-in wire was offered molding metal mold, propeller advanced, and formed the U font between with molding metal mold.By propeller the peristome of the lead-in wire that forms the U font from metal pattern extruded, insert the interior between groove of support.Because the lead-in wire that forms the U font has both ends by the open laterally characteristic of resilience (springback), the elasticity that just then goes between by both ends remains on the interior in groove of support.The different lead-in wire contacts of propeller in statu quo retreat.Then, keeping the support of lead-in wire to descend, when near the maintenance tooth of going barrel, the both ends of lead-in wire are at first with the spigot surface contact, make the spigot surface bending to the inside of sliding on one side.Then, buckling surface is inserted at the both ends of lead-in wire when support descends.Wherein, because the interval of buckling surface is narrower than the interior to the interval of groove of support, come off to groove from interior in the step of lead-in wire insertion buckling surface, if make on the support under this state, lead-in wire just flexibly remains on the going barrel.

Above-mentioned angle of rake moving forward and backward with moving up and down of support kept synchronously, and the state lower carriage that advances at propeller can not descend.For the lead-in wire that remains on the support is transferred on the maintenance tooth of going barrel, the rotation of going barrel and moving up and down of support are kept synchronously.

The rotation of going barrel can be rotation continuously or be interrupted rotation, then when continuous rotation, just need make the rotary speed of the speed that moves up and down of support greater than going barrel.

tooth

13,13 greater than the fore-and-aft direction of support 9.Therefore, when descending, just can amplify between the

maintenance tooth

13,13 on support 9.As shown in Figure 3, form the spigot surface 13a of involute shape in the two sides that keep tooth 13 and form vertical buckling surface 13b in its bottom, the buckling surface 13b interval D of adjacent maintenance tooth 13 is less than the interior A/F W to groove 10 of above-mentioned support 9.Keeping between the tooth 13 by keeping tooth 13 to form small-sized center tooth 14.

Shown in the dotted line among Fig. 3, like that, the groove 13c that lead-in wire 4 inserts is set on buckling surface 13b.

The following describes the action of the transfer device that constitutes by said structure.

At first, by Fig. 4 the method that lead-in wire 4 is shaped to the U font is described.

Then, as Fig. 4 (b), cut-out guide rail 7 is forwards slided with respect to metal pattern 1, cutting off the end, front and back that cuts off lead-in wire 4 between guide rail 7 and the module 2 simultaneously, and obtaining the lead-in wire 4 of certain-length.At this moment, metal pattern 1 is fixed on certain position, cut-out guide rail 7 is advanced, and cut-out guide rail 7 is fixed on certain position, metal pattern 1 is retreated.

Then, propeller is advanced towards peristome 3, as Fig. 4 (c), the central portion of the straight lead-in wire 4 that is cut into certain-length is forwards pressed, between propeller 6 and module 2, form the U font.

When propeller 6 was advanced, the lead-in wire 4 that forms the U font was forwards extracted out from peristome 3, inserted the interior to groove 10 (referring to Fig. 4 (d)) of support 9.At this moment, since lead-in wire 4 have outside elasticity and lead-in wire 4 stably remained in the support 9 by resilience force.

When propeller 6 is retreated, do not push down propeller 6 owing to carve lead-in wire 4 at this moment, and lead-in wire 4 is stayed in the support 9, only propeller 6 in statu quo retreats.

Illustrate from the transfer action of support 9 with Fig. 3 below to going barrel 11.

When going barrel 11 arrived position shown in Figure 3, support 9 began to descend.When arriving the A position of Fig. 3, the both ends of the lead-in wire 4 in remaining in groove 10 keep the spigot surface 13a of tooth 13 to contact together, and along with the decline of support 9, slide and bending to the inside along spigot surface 13a in the both ends of lead-in wire 4.Support then descends, and in the B position of Fig. 3, promptly going between 4 embeds in the step of buckling surface 13b, and the both ends of lead-in wire 4 come off to groove 10 from interior, and lead-in wire 4 remains among the buckling surface 13b by its elasticity.In this step, when support 9 was risen, only support rose, and lead-in wire 4 is stayed on the maintenance tooth 13 of going barrel 11.Like this, the transfer action that is through with and goes between.

In the above-described embodiments, each drive source of propeller, support and going barrel is set respectively, and constitute these drive sources is kept synchronously mutually, but be not limited in this, also can drive propeller, support and going barrel three with a drive source.In the case, in order to seek the synchronous of three, mechanism synchronously such as cam, connecting rod or gear just need be set in addition.

Going barrel is not limited in this of continuous rotation, also can be to be interrupted rotation with certain pitch interval.

From above explanation as can be seen,, after forming lead-in wire, transfer on the support, directly shift to the maintenance tooth of going barrel with propeller according to the present invention, thereby, just not needing to use auxiliary material such as existing paper tape, just can reduce cost.

Owing to need on going barrel, not be provided for extracting out the mechanism of lead-in wire, just can simplify the structure of going barrel itself from medium.

Because the transfer of lead-in wire has utilized self the elasticity of going between, do not need complicated maintaining body, become simple structure.For this reason, just improved reliability, can constitute at an easy rate fault.
