Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a core insertion machine that alternately inserts E-type iron plates and I-type iron plates from the left and right sides of a coil.

The core insertion machine of the present invention has a coil 1 as shown in FIG.
This is a machine that mechanically inserts E-shaped iron plates 2 and working-shaped iron plates 3 alternately from the left and right sides.

This type of conventional iron core insertion machine uses the ejecting pawl to eject the E-shaped iron plate and the ■-shaped iron plate one by one from the case during the first stroke of the feed pawl, and stacks the iron plate with the work-shape iron plate on top, and then feeds the iron plate. When the claw moves backwards, the E-type iron plate and the work-type iron plate are stopped by the E-type check brake plate and the I-type check brake plate from moving backwards toward the feed claw, so that they overlap in the next stroke of the feed claw. The E-type iron plate and the I-type iron plate are moved along the guide rail by the insertion claws and inserted into the coil.

Since such a core insertion machine is equipped with both an E-type check brake plate and an I-type check brake plate, there are many parts, and it is also difficult to see the movements of the E-type iron plate and the work-type iron plate.

In addition, since the lower end of the E-type check brake plate is located below the guide rail surface, when the E-type iron plate and the ■-type iron plate pass under the E-type check brake plate, the E-type check brake plate is pushed up greatly. The vertical movement of the E-type check brake plate is large.

Therefore, scratches are formed on the surface of the E-type iron plate and the engineering-type iron plate by the E-type non-return brake plate.

Scratches will adversely affect the properties of the iron core.

There are a lot of scratches because there are scratches due to the engineered non-return brake plate.

Furthermore, the I-type iron plate as well as the E-type iron plate require a long stroke because they are once stopped by a non-return brake plate to prevent them from moving backwards.

In addition, other types of conventional iron core insertion machines have the same structure in which the E-type iron plate and I-type iron plate are once stopped so as not to move backwards, and then inserted during the next stroke, so the above-mentioned method is also applied. There were some problems.

The object of the present invention is to solve the above-mentioned problems by eliminating the need for back-checking the I-type iron plate.
The purpose of the present invention is to provide a type of iron core insertion machine.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 7.

FIG. 2 shows its front view, and FIG. 3 shows its plan view.

A motor, a speed reducer, etc. are housed in the base 4, and an operation switch 5, a power indicator lamp 6, and a manual handle 7 are attached to the front of the base 4.

A pair of front and rear side frames 8 are fixed on the base 4.

The intervals between the side frames 8 are fixed by the stay plates 9 being inserted therebetween.

At the center of the side frame 8 is a coil holding claw 10.1 that holds the coil 1 or the coil bobbin around which the coil 1 is wound.
0' is provided.

The bases of the coil holding claws 10, 10' are fixed to shafts 11, 11', and a handle 12 is connected to the shaft 11'.

The shafts 11, 11' are operatively connected via opening/closing cams 13.14.

The coil holding claws 10 and 10' are constantly subjected to force in the direction of holding the coil 1 or coil bobbin by a spring (not shown), and when the handle 12 is pushed down, they open against the force of the spring and hold the coil 1 or the coil bobbin. allows for attachment and detachment.

Cases 15 and 15' for accommodating the E-type iron plate 2 and the working-type iron plate 3 are provided at left-right symmetrical positions of the coil holding claws 10 and 10'.

Since case 15 and case 15' are symmetrical, only case 15 will be described.

A pair of narrow vertical plates 16 and a pair of wide vertical plates 17 are fixed onto the side frame 9 by means such as welding.

The inner surfaces of the vertical plates 16, 1T and the inner surface of the side frame 8 are aligned in the same vertical plane.

The inside of the side frame 8 and the vertical plates 16,17 are shown in FIG. 4, and a guide rail 18 is mounted horizontally on the inside of the side frame 8.

A first dividing column 19 is attached to the inner surfaces of the vertical plate 16 and the side frame 8, and the lower end surface of the first dividing column 19 abuts the upper surface of the guide rail 18.

A second partition column 20 and a third partition column 21 are attached to the inner surfaces of the vertical plate 17 and the side frame 8.

The gap between the lower end surface of the second partition column 20 and the upper surface of the guide rail 18 is set to a size that allows one E-shaped iron plate 2 to pass through,
This gap forms an E-shaped protrusion 22.

Between the second division pillar 20 and the third division pillar 21 and the third division pillar 2
An I-shaped receiving plate 23 is disposed below the guide rail 18 and above the guide rail 18, and the square-shaped receiving plate 23 integrally has a mounting portion 24 fixed to the side frame 8, as shown in FIG.

The gap between the lower end surface of the third partition column 21 and the working mold receiving plate 23 is set to a size that allows one of the I-shaped iron plates 3 to pass through, and this gap forms the I-shaped protrusion 25.

(2) The gap between the lower surface of the shaped receiving plate 23 and the upper surface of the guide rail 18 is equal to or larger than the height of the E-shaped protrusion 22.

A space 26 for accommodating the E-shaped iron plate 2 is formed between the first partition column 19 and the second partition column 20, and a space 26 for accommodating the E-shaped iron plate 3 between the second partition column 20 and the third partition column 21. A space 27 is formed.

The upper surface of the guide rail 18 has a small portion near the first partition column 19 that is raised one step, for example, by about 0.2 mm, and because of this stepped portion 28, the E-shaped iron plate 2 can protrude without coming off the E-shaped claw portion. be done.

Guide rail 18 adjacent to coil holding claws 10, 10'
The upper surface of the holder is further raised to form a high trail portion 29.

Four non-return brake plates 30. are placed on the guide rail 18 between the case 15.15' and the coil holding claw 10.
30' are arranged respectively.

The non-return brake plate 30 is shown in FIG. 4, and its front end is inserted into the notch β1 (FIG. 5) provided in the third partition column 21 and comes into contact with the upper surface of the mold receiving plate 23. come into contact with

The rear end portion of the non-return brake plate 30 contacts the ground surface of the guide rail 18.

A protrusion 32 is provided on the side frame side of the non-return brake plate 30.
A bolt 34 into which a spring 33 is inserted passes through the protrusion 32 and is screwed and fixed to the side frame 8.

Therefore, the spring 33 is located between the head of the bolt 340 and the upper surface of the protrusion 32, and the check brake plate 30 is pressed onto the guide rail 18 by the spring 33.

The check brake 30 is a check part 3 that stops the E-type iron plate 2 from moving backwards.
5.

An E-type presser roller 36 is attached by a shaft 37 between the pair of front and rear check brake plates 30.

As shown in FIG. 5, the ■-shaped presser member 38 is attached to the third partition column 21 by an attachment arm 39.

In the section directly below the guide rail 18 of the side frame 8,
As shown in FIG. 5, the slide guide member 40 is fixed, and the slide base 41 is slidably disposed between the guide rail 18 and the slide guide member 40. As shown in FIG.

The slide base 41 is connected to an eccentric disk (not shown) disposed within an eccentric disk cover 42.

The eccentric disk is connected to a speed reducer. Slide base 41
A feed pawl 43, 43' is fixed to.

The feed pawl 43 is shown in FIG. The feed claw 43 includes an E-type claw part 44 and an EI-type claw part 45.

The E-type claw portion 44 is higher than the step portion 28 of the guide rail 18 by the thickness of the E-type iron plate 2.

The claw portion 45 for the EI type is still higher than the ■ type receiving plate 23 by the thickness of the I type iron plate 3.

The operation will be explained with reference to FIG.

The coil bobbin 46 on which the coil 1 is wound is the coil holding claw 1
010'.

The state shown in FIG. 7 shows the state in which the slide base 41 is at the rightmost position.

When the operation switch 5 is closed and the motor is driven, the slide base 41 starts moving to the left.

The E-shaped claw part 44 hooks the lowest E-shaped iron plate 2 in the case 15 and projects it from the E-shaped protrusion opening 22.

At the same time, the EI-type claw portion 45 projects the lowest mold iron plate 3 from the mold protrusion 25.

■As soon as both ends of the type iron plate 30 exit from the I-type protrusion 25,
Since it passes under the front end of the non-return brake plate 30 while pushing it up, it is braked, and the center part is held down by the I-type holding member 38.

Therefore, the molded iron plate 3 will be held down at three points,
Both ends advance at the same time and are never diagonal.

Since the E-type iron plate 2 carried by the previous feed claw 430 stroke is placed at the position where the I-type iron plate 3 comes off the ■-type receiving plate 23, the ■-type iron plate 3 is stacked on top of the E-type iron plate 2. is,
The two iron plates 2 and 3 stacked in this way are guided to the side frame 8 and guide rail 18 by the EI type claw part 45, and are sent from below the E type iron plate 2 inserted into the coil bobbin 46. inserted into.

On the other hand, the E-type iron plate 2 fed by the E-type claw portion 44 is carried to an intermediate position between the case 15 and the coil bobbin 46.

At this time, the tip of the E-type iron plate 2 is connected to the check brake plate 30.
When it enters the E-type holding part 47 (Fig. 4),
The slide base 41 starts to return, but since the tip of the E-shaped iron plate 2 is held down by the E-shaped holding part 4T, the E
The mold plate 2 does not move backwards.

When the EI type claw portion 45 passes under the rear end of the E type iron plate 2, the rear end of the E type iron plate 2 is pushed up.
It is caught by the check portion 35 of the check brake plate 30 and is prevented from moving backward.

When the EI type claw portion 45 has completely passed by, the E type iron plate 2 falls onto the guide rail 18.

The above operation is similarly performed on the left side of the coil holding claws 10 and 10', and the left and right sides are repeated alternately to insert the E-type iron plate 2 and the work-type iron plate 3 into the coil bobbin 46.

In addition, when the center leg of the E-type iron plate 2 is bent upward, the E-type holding roller 36 holds it down and prevents it from being inserted on top of the E-type iron plate 2 inserted in the previous stroke. It is something to prevent.

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

Further, means other than the coil holding claws 10 and 10' can be used as the coil holding portion.

As explained above, according to the present invention, the work-shaped iron plate is protruded from the case, and the above-mentioned While stacking the iron plates, an EI type iron plate is formed on the feed pawl to feed the E type iron plate and ■ type iron plate and insert them into the coil during one stroke of the feed pawl. Since I pushed it out and then inserted it into the coil all at once, there was no need to back-check the I-type iron plate.

Therefore, it is possible to eliminate the mechanical check brake plate,
The number of parts can be reduced.

Since the non-return brake plate is only placed on the guide rail, it is possible to easily see the movement of the E-type steel plate and ■-type steel plate, and the corners of the E-type steel plate and work-type steel plate are wedged into the side frame. Even if it stops working, you can easily take out the iron plate.

The check brake plate is still placed on the guide rail and is different from the conventional one, which is located below the guide rail surface, so the vertical movement of the check brake plate is small, and the vertical movement of the check brake plate causes problems such as E-type iron plates and I-type iron plates. The impact on the iron plate can be almost completely eliminated.

Therefore, in addition to the small number of non-return brake plates, it is possible to almost eliminate scratches on the iron plate.

Furthermore, once the molded iron plate is ejected from the case, it is inserted into the coil by the same stroke of the feed claw, so the stroke can be shortened.
