Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a core insertion machine that alternately and sequentially inserts E-type iron plates and summer-type iron plates from the left and right sides of a coil wound around a bobbin or a hollow coil.

The iron core insertion machine of the present invention mechanically inserts E-type iron plates 3 and summer-type iron plates 4 alternately from the left and right sides of a coil 2 or a hollow coil wound around a bobbin 1, as shown in FIG. It's a machine.

This type of conventional iron core insertion machine uses the protruding pawl to eject the E-type iron plate and the summer-type iron plate one by one from the case during the first forward stroke of the feed pawl, and stack them so that the summer-type iron plate is on top. .

When the feed pawl moves back, the E type check brake plate and the ■ type check brake plate prevent the E type iron plate and the ■■ iron plate from moving backward together with the feed pawl.

In the next stroke of the feed claw, the overlapping Ell iron plate and summer type iron plate are moved along the guide rail by the insertion claw portion and inserted into the coil.

However, with this iron core insertion machine, the E-type check brake plate and the I
Since it has both fi non-return brake plates, there are many parts, and it is difficult to see the movement of the E type iron plate and the summer type iron plate. In addition, the lower end of the EW check brake plate is located below the guide rail surface, so when the E type iron plate and the summer type iron plate pass under the E type check brake plate, the E type check brake plate is pushed up greatly, and the Efi type check brake plate is pushed up. The vertical movement of the non-return brake plate is large. As a result, the surface of the E-type iron plate and Ill iron plate is scratched by the E-type check brake plate and ■-type check brake plate.
It has a negative effect on the properties of the iron core. Furthermore, along with the E-type iron plate, the summer-type iron plate also has the drawback of requiring a long stroke due to the fact that it is stopped from moving backwards by the -H non-return brake plate.

The present applicant has previously proposed an iron core insertion machine that eliminates these various drawbacks. As shown in Fig. 2, this iron core insertion machine has E[iron plates 3 and LFI iron plates 4] stacked individually at symmetrical positions of the coil holding claws 5.5 that hold the coil 2 wound around the bobbin 1. A case 6 is provided in which the E-shaped iron plates 3 are accommodated, and the case 6 has an E-shaped protrusion opening from which the E-shaped iron plates 3 are ejected one by one, and a ■-shaped ejection opening which is placed above the E-shaped protrusion opening from which the summer-shaped iron plates 4 are ejected one by one. do. The feed claw 7 is arranged so as to reciprocate from side to side, and the E-type claw portion 8 is attached to the feed claw 7.
Then, the E-type iron plate 3 is pushed out from the case 6 using the E-type claw part 8 and sent to an intermediate position between the case 6 and the coil holding claw 5. On the other hand, the IW iron plate 4 is protruded from the case 6 using the EIW claw part 9, and the summer type iron plate 4 is stacked on top of the E type iron plate 3 placed at the intermediate position.
Insert the molded iron plate 3 and summer molded iron plate 4 into the coil 2. Further, the E-shaped iron plate 3 sent to the intermediate position is stopped by the E-shaped iron plate 8 so as not to move backward when the feeding claw 7 moves backward, and the E-shaped iron plate 3 and the summer-type iron plate 4 that are being sent are braked. A check brake plate 10 is arranged between a coil holding claw 5 and a case 6.

In addition, in the figure, 11 is a slide pace equipped with the feed pawl 7, 12 is a slide guide member that guides the reciprocating movement of the slide pace 11, 13 is a summer type receiving plate, and 14 is a press against the center leg of the E type iron plate 3. The E-type presser roller 15.15 is a rotating wheel of the coil holding claw 5.5.

This iron core insertion machine has a simple structure, the movement of the E-type iron plate 3 and the summer type iron plate 4 is easy to see, and the upward and downward movement of the non-return brake plate 10 is small. It has various advantages such as almost no shock (・・
There are some difficulties (not an S translation).

That is, depending on the form of the coil, the lead wires may come out, for example, at two or four locations on the top and bottom. When installing such a coil in a core insertion machine and inserting an E type iron plate or a summer type iron plate, it is necessary to set the lower lead wire through the core insertion machine each time the coil is installed. It takes time to set up. Furthermore, when taking out the coil from the core insertion machine after inserting the core, the lower lead wire may catch a bow on a part of the core insertion machine, causing the lead wire to break.

An object of the present invention is to provide an iron core insertion machine that eliminates the drawbacks of the prior art and can smoothly set and take out even coils in which lead wires are provided at the top and bottom. .

It is equipped with two non-return brake means arranged.

Each of the cases is provided with an E-shaped ejection opening from which one E-shaped iron plate comes out, and an I-shaped ejection opening, which is arranged above the E-shaped ejection opening and from which one ■-shaped iron plate comes out, The feed pawl includes a gm pawl that protrudes the E-shaped iron plate from the case and transfers it to an intermediate position between the case and the coil holding means while being guided by the guide member, and a GM pawl that protrudes the ■-shaped iron plate from the case and transfers it to an intermediate position between the case and the coil holding means. While stacking the I-shaped iron plate on top of the E-shaped iron plate transferred by the stroke of established,
The non-return brake means is transferred when the feed pawl moves forward.
In addition to applying braking to the type iron plate and the type I iron plate, the claws for the type E are used to move the intermediate position! In the iron core insertion machine configured to prevent the E-type iron plate transferred to the reverse direction from moving backward during the return movement of the feed claw, the coil holding means is perpendicular to the direction of transfer of the E-type iron plate and the ■-type iron plate. The coil holding means is pulled out from the guide member, the coil is set, and after setting, the coil holding means is attached to the E-type iron plate and! Place it on the transfer route of the iron plate,

Both left and right ends of the E-shaped iron plate 3 and the ■-shaped iron plate 4 inserted into the coil 2 are supported by the bent end of the round bar 80.

Figure 12 shows the initial state of inserting the iron plate 3.4.
At this time, the side end of the link 750 is not in contact with the stopper 78. As the amount of the iron plate 3.4 inserted into the coil 2 gradually increases, the inserted iron plate support arm 74 and the link 75j rotate accordingly, and the round bar 80 moves directly below the front end surface of the side frame 26. The insertion of the iron plate 3.4 is completed when the side end of the link 75 comes into contact with the stopper 78 as shown in FIG.

There is a predetermined distance between the right and left front side frames 26, 260, and a sliding frame 81 on which the coil 2 wound around the bobbin 1 is mounted and held can be pulled out to the front side between them. It is located. This sliding frame 81 is the first
As shown in FIG. 5, there is a front frame plate 84 to which a handle 82 is attached and has clamping claws 83 on both sides of the rear end surface, a rear frame board 86 having clamping claws 85 on both sides of the front end surface, and the frame board 84.

can be held in a standing state on the sliding frame 81.

As shown in FIGS. 11 and 12, this sliding frame 81 is arranged at the front g4 so as to be orthogonal to the transport direction of the iron plate 3.4.
It is slidably held by a frame rail 88 extending from the RTC. As shown in FIG. 11, connecting rods 89 are attached to the lower surface of the frame rake 88, facing downward, on the front side and the back side, respectively, and a coil position adjustment plate is installed between the connecting rods 89 and 890. 90 have been erected.

Each of the connecting rods 89 passes through the base 21 through the pushers 93, and therefore the connecting body of the sliding frame 81, frame rail 88, connecting rod 89, and coil position adjusting plate 9o is connected to the adjusting screw 91. It is possible to move up and down.

Although FIG. 11 shows a state in which the coil position adjustment plate 90 (coil 2) is at the lowest position, it is possible to change the position of the coil position adjustment plate 90 with respect to the adjustment screw 91 according to the size of the bobbin 1. , E type iron plate 3 for bobbin 1
In addition, the ■-shaped iron plate 4 can be properly inserted.

Next, the operation of this core insertion machine will be explained.

First, hold the handle 82 and pull the sliding frame 81 toward you,
The lower part of the bobbin 1 with the coil 2 wound thereon is inserted into the sliding frame 81 pulled out to the outside of the front side frame 26.
The bobbin 1 is held between the holding claws 83 and 85 of the sliding frame 81.

Note that the lead @94 connected to the lower part of the bobbin 1 is connected to the bottom of the bobbin 1 when the setting of the front frame 84 and the back frame 86 of the sliding frame 81 is completed, as shown in FIG. , push the sliding frame 81 toward the back along the frame rail 88, and! As shown in FIG. 11, the side end of the bobbin 1 is fitted into the coil fitting claw 64 at 5. This positions the coil 2 on the transport path of the iron plate 3.4.

FIG. 5 shows that the right feed pawl 54 is in a standby state, and at this time the left feed pawl 54 is in the vicinity of the core receiving plate 57. When the operation switch f-22 is turned on and the motor is driven, the eccentric disc operates (the dielectric bar 52 starts moving to the left. As this movement moves, the right feed claw 54 and the left feed claw 54 They each move to the left via the diversion plate 51.

Although there is a timing difference in the insertion operation of the E-type iron plate 3 and the KI-type iron plate 4 by the feed claw 54, the right feed claw 54 and the left feed claw 54 are the same, so here, the right feed claw 54 is inserted.
The operation will be explained.

By moving the feeding claw 54 to the left, the Efi claw portion 56
hooks the lowest E-shaped iron plate 3 accommodated in the accommodation space 41 and projects it from the E-shaped ejection opening 38. At the same time, the EI-type claw part 55 hooks the lowest iron plate 4 housed in the accommodation space 42 and projects it from the I-type ejection opening 40. ■When both ends of the type iron plate 40 come out from the I type protrusion 40,
The end of the non-return brake plate 43 is immediately pushed up against the elasticity of the coil spring 47 and passes under it, thereby applying braking to the transfer operation. Feed claw 5
4, the ejection of the 81M iron plate 3 and the KI type iron plate 4 is done at a fairly high speed, so the ejection of the iron plate 3.4
If the brake is not applied with the non-return brake plate 43, the feed pawl 54
Due to the impact, only the iron plate 3.4 will fly out first, causing various problems. The Ill iron plate 4 is brought to the position where it comes off the die plate 39 by the previous stroke of the feed claw 54.
Since the fi iron plate 3 is placed, the I iron plate 4 is placed on top of the E type iron plate 3, and the two iron plates 3.4 are attached to the side frame 26.27 and the guide rail 34 by the EI type claw part 55. While being guided, the bobbin 1 (coil 2) K is inserted passing over the core receiving plate 57.

On the other hand, the E-type iron plate 3 protruded by the E-type claw part 56
is carried to an intermediate position between the case 31 and the bobbin 1. At this time, the tip of the E-shaped iron plate 3 is connected to the check brake plate 43.
The slide pace 50 (the slide bar 52) begins to return when it enters the E-type holding part 95 (see FIG. 5). However, the tip of the E-type iron plate 3 is sandwiched between the E-type holding part 95 and the side frames 26 and 27.
II iron plate 3 does not go backwards. And the claw part 55 for EI type is E
When passing under the shaped iron plate 3, the rear end of the E-shaped iron plate 3 is pushed up and caught on the non-return portion 48 of the non-return brake plate 43, thereby preventing the E-shaped iron plate 3 from moving backward. When the El type claw part 55 passes, the E type iron plate 3 falls onto the guide rail 34' and waits for the next Ill iron plate 4 to be transferred.

This operation is similarly performed on the left side of the coil 2, and by repeating the left and right operations alternately, the next iron plate is inserted between the iron plate 3.4 that has already been inserted into the bobbin 1 and the bobbin 1. Iron plate 3.4 has already been inserted.
4 is inserted while being pushed down against the elasticity of the tension spring 79 (see FIGS. 12 and 14).

When the insertion of the E-shaped iron plate 3 and the Ill iron plate 4 is completed in this manner, hold the handle 82 and pull the sliding frame 81 toward you to the outside of the front side frame 26, and then slide the bobbin 1. It is taken out from the moving frame body 81.

The present invention can be applied not only to an automatic core insertion machine equipped with a motor as a drive source, but also to a hand-cranked manual core insertion machine.

Further, as the coil holding means, means other than the fitting type can also be used.

As described above, in the present invention, the coil holding means can be extracted in a direction perpendicular to the direction of transport of the E-shaped iron plate and the xH iron plate. Therefore, not only the lead wire is connected to the upper side of the coil, but also the lead wire is connected to the lower side of the coil, so that the coil can be set and taken out smoothly. Cutting losses are also eliminated.
