Detailed Description of the Invention

The present invention relates to a method for winding a belt-like body for producing a winding body represented by a secondary battery such as a capacitor such as an electrolytic capacitor, other winding-type small electronic components, and a small to large-sized lithium ion battery. In particular, in a winding method and apparatus for winding a band-like body around a winding core divided by a split groove and winding the band-like body, the winding is formed on at least one core portion. Insert the needle-like body in the axial direction into the split groove through the groove, and take up the strip-like body so that the winding core does not become thin enough to close the split groove by the tightening force accompanying the winding of the strip-like body After the winding is finished, the needle-shaped body is removed from the core and allowed to bend, so that it is an extremely simple mechanism. Is firmly held by the core and slipped During winding, make sure that the winding core does not bend like a drum, and when removing the wound winding body from the winding core, there is a gap between the winding core and the winding body. The present invention relates to an epoch-making method and an apparatus for winding a belt-like body that can be easily pulled out.

Conventionally, in a capacitor such as an electrolytic capacitor, a release paper is interposed between positive and negative electrode foils with lead terminals, and these are wound as a band on the winding core of a winder (commonly referred to as “element”) And the wound body is impregnated with a necessary electrolytic solution, etc., and then sent to an assembling machine to be assembled and manufactured as an electronic component, and from small to large lithium ion batteries Similarly, in the secondary battery, a release paper is interposed between the positive and negative electrode foils to form a belt-like body, which is wound around the core of the winder, and then the electrode is attached to wind the secondary battery. A body is formed, and these electronic components or secondary batteries are manufactured.

In the winding method and apparatus for a belt-like body for producing such a wound body, the winding core 1 of a conventional winding machine (not shown) is first separated by a split groove 2 as shown in FIG. The winding core portion 11 and the second winding core portion 12 are divided into two parts. The winding start end portion 3a of the belt-like body 3 is inserted into the dividing groove 2, and the first winding core portion 11 and the second winding core portion 12 are inserted. Then, winding is started, and the wound body 4 is formed around the core 1 as shown.

On the other hand, the core 1 is generally made of super steel, but its bending strength is not so great because its diameter is small for its length. For this reason, as the winding of the strip 3 progresses, the force for tightening the core 1 in the radial direction increases, and finally the central portion in the width direction of the strip 3 is most greatly bent as shown in the figure. While strongly pressing the winding start end portion 3 a of the belt-like body 3, also between the outer peripheral surface 11 a of the first core portion 11, the outer peripheral surface 12 a of the second core portion 12, and the inner peripheral surface 4 b of the wound body 4. A strong compressive force acts and is strongly tightened. As a result, the wound body 4 at the end of winding is formed in a drum shape whose center in the width direction is recessed.

Conventionally, from this state, one end 4a of the wound body 4 is pushed leftward in the figure by a pressing member (not shown), and the wound body 4 is removed from the core 1 for the reasons described above. Since the wound body 4 is formed in a particularly drum shape, it is very difficult to extract the wound body 4 and must be extracted against a large resistance.
At this time, the band-shaped body 3 constituting the wound body 4 has almost no restraint by the core 1 in the outer portion as the wound body 4, and therefore when the side surface is pressed by the pressing member, the band-shaped body close to the outside. The movement of the belt-shaped body 3 is delayed as 3 moves ahead and advances toward the middle, and a shift occurs between the layers of the belt-shaped body 3. Moreover, since the strip | belt-shaped body 3 is restrained by the core 1 with a strong force in the part close | similar to the core 1, a wrinkle will arise when it is pressed by a press member.
Due to the gaps and wrinkles between the layers of the belt-shaped body 3, they often become defective products, and even when they do not become defective products, friction occurs due to the displacement between the layers of the belt-shaped body 3. The conversion coating (not shown) applied to the surface of the (not shown) could be damaged, resulting in a product with poor electrical properties.

In the winding method and apparatus for winding the winding body even in a very small electronic component such as a small electrolytic capacitor, a considerably large electronic component other than this, and a product such as a small to large secondary battery. This is a common problem, and in the prior art, this problem is regarded as a drawback of a large manufacturing state, but there is no solution.

Since the present inventor and the present applicant do not know patent documents related to the present invention, the description thereof is omitted.

Since the present inventor and the present applicant do not know non-patent literature relating to the present invention, the description thereof is omitted.

The point that the gap S is formed between the split groove surface 22c of the winding core portion 22 is the same as in the first embodiment.

Next, the winding method according to the present invention will be described. The method for winding a belt-like body according to the present invention (Claim 1 ) includes winding the belt-like body 3 around a core 8 divided into a first core portion 21 and a second core portion 22 by a split groove 6. In the winding method of the belt-shaped body that winds the belt-shaped body and becomes the wound body 4, the winding core is separated from the core by the tightening force that acts on the core 8 from the belt-shaped body during winding of the belt-shaped body 3. A needle-like shape in which an inclined surface 9b is formed at one end of a groove 21b formed in the axial direction of either one or both of the first core portion 21 and the second core portion 22 so as not to bend to the extent that it is closed. By inserting the body 9 and constraining the needle-like body in the rotational direction with respect to the winding core 8, the rotational direction position of the inclined surface 9b is kept constant, and the belt-like body 3 is wound along the inclined surface 9b. The start end 3a is inserted into the split groove 6 to start winding, and the winding core 8 is split by the tightening force accompanying the winding of the band-shaped body 3. In this method, the belt-like body 3 is wound so as not to become thin until the groove 6 is closed, and after the winding is completed, the needle-like body 9 is removed from the core 8 to allow the core 8 to bend. .

The present invention is configured as described above, and the operation (first embodiment) will be described below. In FIG. 9, when winding the belt-shaped body 3, first, the needle-shaped body 9 is moved to the winding core 8 by the needle-shaped body insertion / removal mechanism 10 with respect to the rotation drive unit 14 of the belt-shaped body winding device 5. In this case, the insertion is performed so that the protrusion 16a of the insertion / removal drive unit 16 enters the groove 14a of the rotation drive unit 14 with reference to FIG. As a result, the needle-like body 9 is restrained in the rotation direction by the rotation driving unit 14, and the rotational direction position of the inclined surface 9b of the needle-like body 9 is always directed in a certain direction. 9 to 11, the inclined surface 9b is set so as to always face upward.

At this time, the rotary support 13 is removed from the core 8, and the strip 3 can be inserted along the split groove 6 from the end 8d of the core 8 with some tension applied. ing.
Therefore, in FIG. 9, the belt-like body 3 is inserted into the split groove 6 of the winding core 8 in the horizontal direction as indicated by an arrow C. As shown in FIG. 10, when the belt-like body 3 is inserted to some extent, the side surface 3b eventually reaches a position where it contacts the needle-like body 9, but an inclined surface 9b is formed at one end 9a of the needle-like body 9. Therefore, as shown in FIGS. 11 and 16, the belt-like body 3 is smoothly pushed up along the inclined surface 9 b, and the outer peripheral portion 9 d of the needle-like body 9 and the split groove surface of the second core portion 22. It enters into the clearance S between 22c. At this time, since the gap S is substantially the same as the thickness of the belt-like body 3, a slight frictional force is generated between the split groove surface 22 c of the second core portion 22 and the belt-like body 3 and the outer peripheral portion 9 d of the needle-like body 9. The winding start end portion 3a of the belt-like body 3 is held here.

Therefore, as shown in FIG. 10, the rotary support 13 is attached to the core 8 as indicated by the arrow D, and the strip 3 is cut at the outer diameter portion 8 e of the core 8 as shown in FIG. 16. At this time, as described above, the winding start end portion 3a of the belt-like body 3 is held by the second core portion 22 of the core 8 and the needle-like body 9 by a slight frictional force, and does not come off. Preparation for winding is completed.

When the preparation for winding is completed in this way, the winding core 8 starts to rotate as indicated by the arrow E by the rotation drive unit 14 as shown in FIGS. As a result, winding is immediately started, and at that moment, the clamping force as indicated by arrows F and G is generated in the winding core 8 by the resistance tension of the belt-like body 3, and the split groove surface 22 c of the second winding core portion 22 and the needle-like body 9. The winding start end portion 3a of the belt-like body 3 is pressed and firmly held by the outer peripheral portion 9d without slipping, and the winding proceeds as shown in FIGS. 13 and 18 to complete the winding, A wound body 4 is formed.
At this time, due to the presence of the needle-like body 9 which is the greatest feature of the present invention, the first core portion 21 and the second core portion 22 of the core 8 cannot be bent to the extent that the split groove 6 is closed. Therefore, no matter how strong the tightening force as indicated by arrows F and G from the belt-like body 3 is, or no matter how long the core 8 is, the core 8 will not be bent in a drum shape. The central portion in the width direction is not thinned and deformed into a drum shape (see the conventional example in FIG. 28), and winding is completed in a parallel state.

The insertion of the needle-like body 9 into the core 8 may be performed by changing the insertion depth depending on the width of the belt-like body 3 to be wound. The needle-like body 9 is inserted to a depth slightly wider than the width of the belt-like body 3. do it. For this reason, it is possible to take up the belt-like body 3 having a very narrow width or a very wide belt-like body 3 by changing the insertion depth of the needle-like body 9 into the core 3, which is very small. It is possible to wind up from an electronic component such as an electrolytic capacitor to a wound body 4 such as an extremely large secondary battery.

When the winding is completed, the belt-like body 3 is cut, and the tape 19 is applied to the winding end 4c of the belt-like body 3 as shown in FIGS. Is completed, and the process of removing the wound body 4 from the core 8 is started.

In FIG. 14, the needle-like body insertion / removal mechanism 16 is activated, and the insertion / removal drive portion 16 of the needle-like body 9 is pulled out from the rotation drive portion 14 of the winding core 8 as indicated by the arrow H. The whole is pulled out from the core 8. As a result, the core 8 has no resistance from the inside, and as shown in FIG. 19, the first core portion 21 and the second core portion 22 are allowed to bend by the tightening force as indicated by arrows F and G. As a result, it bends to the extent that the split groove 6 is eliminated. As a result, a gap S2 is generated between the inner peripheral surface 4b of the wound body 4 and the outer diameter portion 8e of the winding core 8, and the wound body 4 It will be in the state which is easy to remove from easily.
Therefore, the rotary support 13 is removed from the winding core 8 as indicated by an arrow I, and the pressing collar 18 is slid as indicated by an arrow J, so that the winding body 4 can be easily pushed out of the winding core 8 as indicated by an arrow K. As a result, no deviation occurs between the layers of the belt-like body 3 of the wound body 4, and the belt-like body 3 is removed from the core 8 without damaging the electrode foil or the like. Then, the winding of one wound body 4 is completed.
As a result, the wound film 4 having extremely excellent electrical characteristics can be obtained without causing any damage that deteriorates the electrical characteristics on the chemical conversion film or the like of the electrode foil of the strip 3 constituting the completed wound body 4. Can be manufactured.

Next, the operation of another embodiment (second embodiment to ninth embodiment) of the present invention shown in FIGS. 20 to 27 is basically the same as the operation of the first embodiment, and therefore, the redundant description is omitted. Although omitted, the second embodiment to the fifth embodiment are the same as the first embodiment, and the winding core 8 has an elongated cross section from the sixth embodiment to the ninth embodiment. Therefore, a phenomenon in which a part of the wound body 4 swells by the thickness of the lead terminal (not shown) attached to the electrode foil of the strip 3 is suppressed, and as a result, the wound body has a cross section close to a true circle. 4 is more advantageous than the core 8 having a circular cross section. For this reason, these examples are particularly used for winding the wound body 4 of an electronic component such as a small electrolytic capacitor and exhibit its effect.
