DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crease mechanism for a tape or a tape-like material. For example, when an electronic component is shipped in a state of being carried on a long tape, such a long tape-like material is used. Is suitable for being folded in a zigzag manner at regular intervals and packed.

[0002]

2. Description of the Related Art For example, a general resistor having a pair of lead legs projecting coaxially from both ends of a main body, as shown in FIG. A shipping form is adopted in which the individual lead feet are supported by a long tape in a lined up manner.
In this manner, the tape-like material having the electronic components carried by the tape is folded and folded in a rectangular box having a width corresponding to the width of the tape-like material, and stored, packed, and shipped.

FIG. 5 shows an example of a conventional apparatus for packing the above-mentioned tape-shaped material in a zigzag manner. Reference numeral 1 denotes an introduction mechanism for introducing the tape-shaped material 2 at a constant speed. The tape-shaped material 2 is held between the feed roller 3 and the pressing roller 4 and is rotated by a predetermined amount with the rotation of the feed roller 3. Sent downward at speed. A swing guide 5 that swings back and forth is disposed below the introduction mechanism, and the swing guide 5 is a tape-like material 2 that is fed downward between the two front and rear guide plates 5a and 5b as described above. While being passed through, is swung in the front-rear direction (the left-right direction in FIG. 1) by a not-shown swing mechanism.

Below the swing guide 5, a loading mechanism 7 for loading the tape-shaped material 2 into the rectangular box 6 while folding the tape-shaped material 2 in a zigzag manner is arranged. Above the opening of the rectangular box 6, a swing shaft 10 oscillated by an arm 9 while being advanced and retracted by a cylinder 8 is disposed. In addition, crease plates 11 and 12 are swingably disposed at portions corresponding to the front and rear ends of the opening of the rectangular box 6, respectively.

[0005] Reference numeral 13 denotes a bottom plate supported inside the rectangular box 6, and the bottom plate is supported by upper ends of a plurality of telescopic rods 14 extending through the bottom of the rectangular box 6. The bottom plate 13 is initially provided with the telescopic rod 1.
The upward movement of the tape 4 raises it to the vicinity of the opening of the rectangular box, and the tape-shaped object is gradually lowered as it is successively folded and loaded into the rectangular box.

In the above configuration, when the swing guide 5 moves toward, for example, one end of the opening of the rectangular box 6, the swing shaft 10 advanced by the cylinder 8 is sequentially fed out from the lower end of the swing guide 5. The tape-shaped object 2 is moved in the same direction as following the tape-shaped object 2, and the tape-shaped object 2 is pulled to one end of the opening of the rectangular box 6. At the next moment, the swing shaft 10 is retracted, and the creasing plate 11 in the standing state presses the tape-like material 2 from above as shown by the imaginary line in FIG. .

Next, even when the swinging guide 5 moves in the opposite direction in accordance with the amount of the tape-shaped material fed, the advanced swinging shaft 10 is moved in the same manner as described above.
Is moved in the same direction as to chase the tape-shaped material 2 fed out of the box, and the tape-shaped material is pulled to the other end of the opening of the rectangular box 6. At the same time, the swing shaft 10 is retracted, and the crease plate 12 in the upright state moves as shown by the imaginary line in FIG.

By repeating the above-described operation, the tape-like material 2 is loaded into the rectangular box 6 while being stacked in a zigzag manner. As the stacking height in the rectangular box 6 increases, the telescopic rod 14 moves down, and the bottom plate 13 gradually moves downward. When the rectangular box 6 is filled with the tape-like material 2 folded in a zigzag manner, the cutter 1 provided in the introduction mechanism 1 is provided.
5 operates to cut the tape. When the loading of the tape-shaped object into one rectangular box 6 is completed, the replacement of the rectangular box 6 is performed, and thereafter, the same operation as described above is repeated.

In the above-mentioned conventional mechanism, there are the following problems to be solved. That is, first, when the tape-like material conveyed in a series is folded in a zigzag manner, the tape-like material simply pulled by the swing shaft 10 at one end of the opening of the rectangular box is raised by the crease plates 11 and 12. Since the crease is intended to be performed only by pressing down, the timing of the movement of the swing axis or the timing of retreat, and further, the crease plate 1 related thereto.
Due to the timings of the operations 1 and 12, the tape-like material is not always folded in the opposite direction every fixed length.

[0010] For example, in the shipment form of the resistors as described above, it is necessary to guarantee the number of resistors, for example, to hold 50 resistors in the length of one stack (that is, between folds). However, in the conventional mechanism as described above, it is not always the case that the creasing is performed accurately at every length corresponding to 50 resistors. Therefore, it is difficult to manage the number of electronic components based on the number of folding steps, and the user is inconvenienced.

Second, as described above, it is not always the case that the creases are formed at every fixed length and are not always folded in a zigzag manner. Therefore, when the number of electronic components to be loaded in one box is constant. However, the position of the end of the tape-shaped material varies in the longitudinal direction of the opening of the rectangular box, which is also inconvenient for the user side, and is not preferable in appearance with the rectangular box opened.

The present invention has been devised in view of the above circumstances, and is intended to fold a tape or a tape-shaped object in a zigzag manner so that the tape or tape-shaped object can be accurately folded for each fixed length. That is the challenge.

[0013]

Means for Solving the Problems To solve the above problems, the present invention takes the following technical means. That is, the tape or tape-shaped creasing mechanism of the present invention comprises a pair of rollers which are rotated in the opposite direction at the same speed around axes separated by a certain range and have substantially the same outer diameter, A guide mechanism for introducing a tape or tape-like material therebetween in synchronization with the rotation speed of the rollers, and one V-shaped concave portion and a mountain-shaped convex portion provided adjacent to each other on a part of the outer periphery of each roller. And a zigzag tooth in which the corresponding V-shaped concave portion and chevron-shaped convex portion are meshed with each other so that a zigzag crease can be formed on the tape or the tape-shaped material. And

[0014]

Since a pair of rollers have substantially the same outer diameter and are rotated in opposite directions, when each roller is provided with one zigzag tooth, the zigzag tooth is formed by the two rollers. Each time it makes one rotation, it meshes with each other on a straight line connecting the axes of both rollers. The tape or tape-like object guided by the guide mechanism between the pair of rollers rotated in this manner at a speed corresponding to the peripheral speed of the rollers is zigzag teeth that mesh with each other at a fixed length interval as described above. A zigzag crease will be formed. This crease is
Because of the zigzag shape, the tape-shaped object is easily folded in any direction with the zigzag crease as a fulcrum.

Therefore, the tape-shaped objects which are folded at regular intervals as described above are stacked while being folded at the above-mentioned folded position when being folded in a zigzag manner. .

Therefore, if the creasing mechanism of the present invention is attached to a mechanism for loading a tape-shaped object while folding it in a zigzag manner, the length of the folded one-stage becomes accurate, and, for example, the electronic component is carried on the tape. In the case of shipping, for example, in a case where the electronic parts are folded in a zigzag shape and loaded in a rectangular box, the number of folded one-stage electronic components can be guaranteed, which makes it extremely easy for the user to manage the number.

Further, if the number of electronic components to be loaded in the rectangular box is set to an integral multiple of the number of one-step folded in a zigzag shape, the position of the terminal of the electronic component tape-like product loaded in the rectangular box can be reduced. In addition, since it is accurately located at one end of the opening of the rectangular box, the handleability on the user side is further improved, and the appearance when the rectangular box is opened becomes constant.

Are folded in a zigzag manner as described below.

Below the slide base 23, a rectangular cylindrical holder 48 is arranged. The internal width of the holder 48 corresponds to the width of the tape-shaped material 20, and the front and rear width of the internal space corresponds to the interval between the creases 43 attached to the tape-shaped material 20. A horizontal holding plate 49 that moves up and down is arranged inside the holder 48. The holding plate 49 is moved up and down by linking an arm 50 that penetrates a slit provided on a side surface of the holder 48 to an external vertical slide mechanism 51.

Next, the tape 20 having the above-described structure
The operation of the folding loading mechanism will be described. Tape 20
As described above, the first guide roller 30, the pair of crease rollers 28 and 29, and the second guide roller 3
1 and is fed while being wound around
The zigzag crease 43 is formed by the zigzag teeth 39 and 40 each time the 8, 29 makes one rotation. The entire slide base 23 that supports the rollers 30, 28, 29, and 31 is reciprocated in the left-right direction in FIG.

First, when the tape-like material 20 hanging vertically from the outer periphery of the second guide roller 31 reaches the holding plate 49 at the uppermost position (see FIG. 1), the slide base 2
FIG. 3 shows a state in which the tape-shaped material 20 is fed downward at a constant speed.
Move to the left of. Then, at the time when the predetermined movement is performed, the crease plate 53 is rotated so as to squeeze and hold the leading end of the tape-shaped material 20 with the holding plate 49. Then, after the slide base 23 moves to the left in FIG. 1 for the same distance as the front-rear length of the upper opening of the holder 48, changes direction and moves to the right again in FIG. Is provided with creases 43 at intervals substantially equal to the front and rear length of the opening of the holder 48,
As described above, once the slide base 23 moves leftward in FIG. 1 and then attempts to move rightward by making a U-turn, the tape-shaped material 20 is bent at the portion where the crease 43 is attached. The folded portion is pressed by the crease plate 54 on the left side of the drawing, so that the folded portion can be more reliably folded.

When the slide base 23 is returning to the right end as shown in FIG. 1, the right crease plate 53 is in a standing retreat position, and the slide base 23 moves leftward again. At this time, the tape 20
Is bent at the portion where the crease 43 is attached in the same manner as described above. Then, this bent portion is securely folded by being pressed by the right crease plate 53.

As described above, since the tape-shaped material 20 is provided with the zigzag fold 43 which is easily bent in any direction at intervals corresponding to the length of the holder 48 in the longitudinal direction. A slide base 23 for feeding the tape-like material 20 downward at a constant speed.
FIG. 1 corresponds to the feeding length of the tape-shaped material 20.
Simply reciprocating in the left-right direction of the
Are bent by the crease 43 and stacked in a zigzag manner. In the embodiment shown in the figure, in addition to the above, crease plates 53 and 54 are provided to make the folding at the crease 43 more reliable.

The holding plate 49 gradually moves downward as the stacking thickness of the tape-like objects 20 in the holder 48 increases. When the tape-shaped material 20 is stacked in a zigzag manner on the holding plate 49 in a constant height, the cutter means including the fixed blade 45 and the movable blade 47 cuts the tape-shaped material 20. This cutting should also be performed at the position of the crease 43 provided on the tape-like material 20, and the end of the tape-like material 20 thus cut is moved from a position corresponding to one of the front and rear walls of the holder 48. They will be stacked without shifting.

Next, the locking plates 56 and 57 assume the locked state shown by the imaginary line in FIG. 3, and the holding plate 49 moves down. Then, the zigzag-shaped laminate of the tape-like material 20 is combined with the locking steps 56a, 5a of the locking plates 56, 57.
It is temporarily held as if riding on 7a. The lowered holding plate 49 receives the supply of the rectangular box 21 from the rectangular box transfer means (not shown) and waits below the holder 48 as shown in FIG. When the locking plates 56 and 57 are set to the retracted positions shown by solid lines in FIG.
The tape-like material 20 temporarily locked and held at 57
The zigzag-shaped laminate is, as shown in FIG.
It is dropped inside 1. The rectangular box 21 containing the zigzag tape-like laminate is transported to the next step by transfer means (not shown).
Is moved up again in the holder 48 and the above-mentioned crease plate 5
The positions corresponding to 3, 54 are taken and the next tape-shaped object is folded and stacked.

As described above, in the above-mentioned tape-shaped object self-folding and laminating apparatus, the long tape-shaped object is previously folded in any direction by the creasing mechanism according to the present invention. Are provided at exactly equal intervals, and when the tape-shaped materials are stacked in a zigzag manner, the tape-like materials are stacked while being alternately bent at an accurate length by the equally-spaced creases 43. Therefore, for example, in a case where the electronic component is loaded in a rectangular box in a zigzag form in a tape-carrying shipping form of the electronic component shown in the drawing, the electronic component is carried by one step length from the fold to the fold, that is, the electronic component is carried by this length The number of electronic components can be guaranteed accurately,
This makes it very easy for the user to control the number of electronic components based on the length from the fold to the fold, thereby greatly improving the convenience for the user.

Further, since the length from the fold to the fold is accurately guaranteed, the terminal position of the laminate loaded in one rectangular box is also constant, which is very difficult for the user side. There is an advantage that the handling convenience is improved and the appearance when the rectangular box is opened is constant.

Of course, the scope of the present invention is not limited to the embodiment described above. In the present embodiment, as a tape-shaped object to be creased, an example in which a plurality of electronic components are carried on a tape at equal intervals has been described.
The aspect of such a tape-shaped material is not at all questioned.
In other words, the object to be folded is a simple tape or a tape-like object in which an article is held on a long tape.
