Description
Thus, an object of the present invention is to provide a packing band, a packing method and a packing apparatus, of little parts, wherein the problems which the said conventional carrier tape has, are solved and the packing work is easy and economical.
A packing band of little parts, according to the present invention, is a band which stores little parts in many storing dents arranged along a longitudinal direction and packs the little parts by covering surfaces of the storing dents with a cover tape, and is made of a flexible material having a compress-forming nature, and comprises storing dents which are compress-formed from a surface to a fixed depth in a thickness direction.
FIG. 1 is a rough front view of a packing apparatus showing an embodiment according to the present invention.
FIG. 7(a) is a sectional view of a press-forming step showing another embodiment, and FIG. 7(b) is a side view of the tape formed in the step shown in FIG. 7(a).
Respective composing elements are concretely explained below.
The depth of the storing dents is established a little shallower than the thickness of the band. The depth of the storing dents is preferably 1/2 or more of the thickness of the band. The depth of the storing dents is preferably 0.35-0.90 mm. The allowable error of the depth of the storing dents is preferably within ±1.5%. The concrete value of the preferable allowable error is different according to the depth of the storing dents and The allowable error is ±0.1 mm in case of the depth of 0.85 mm in maximum and the allowable error is ±0.03 mm in case of the depth of 0.30 mm in minimum. The difference between the thickness of the band and the depth of the storing dents, is the thickness of the bottom portions of the storing dents. To protect sufficiently the little parts, it is preferable to make thick the thickness of the bottom of the storing dents.
A packing apparatus shown in FIG. 1 is a case of packing chip resistances as the little parts 20. As for the chip resistances, for example, a rectangular parallelepiped like chip resistances of 3.2×2.5×0.6 mm and very little chip resistances of about 0.6×0.3×0.3 mm, are known. The thickness range is about 0.3-0.85 mm.
A band reel 10a wherein a band 10 made of a paper material is rolled up in a reel shape, is supported with free-rotating by a reel keeping beam 16. The width of the band is sufficiently wider than the width of the little parts 20 and is, for example, the width of 8 mm, the width of 4 mm. The length of the band 10 is from several hundreds m to a thousand m or more.

One-end of the band 10 is pulled up from the band reel 10a and passes through a guide roll 70 and is supplied to a press-forming portion 50. The press-forming portion 50 travels the band 10 between a flat base 54 and a free fluctuating press mold 52 and press-forms the band by the fluctuating movement of the press mold 52.
In the downstream side of the press-forming portion 50, a packing portion 60 ia arranged via a travelling adjusting portion 10b. The travelling adjusting portion 10b looses a fixed quantity of the band in the midway of guide rolls 70, 70 arranged before and behind. By this loosing of the band 10, the difference of the travelling condition of the band 10 between the press-forming portion 50 and the packing portion 60.
In the packing portion 60, a parts feeder 60, a parts supplying nozzle 62, an image examining tool 66, a cover tape rolling up reel 30a, a heat-seal tool 68 and a rolling up frame 18 are arranged in order in the upper part of the travelling path of the band 10.
The parts feeder 64 stores the many little parts 20 and feeds the little parts in order to the operating position of the parts supplying nozzle 62. The parts supplying nozzle 62 is connected to a vacuum source (not drawn in the figure) and absorbs and keeps the little parts at a pointed end. The image examining tool 66 catches optically the conditions of the band 10 and the little parts 20. Information obtained by the image examining tool 66 is treated by an image treating apparatus (not drawn in the figure) and is examined. To the cover tape rolling up reel 30a, a cover tape 30 made of a transparent synthetic resin film such as a PET resin, is rolled up. In the heat seal tool 68, the band 10 and the cover tape 30 are heat-bonded by a heat-bonding edge 67 established on the lower edge. To the rolling up frame 18, the band 10 packed the little parts 20 is rolled up.
When the band is arranged just under the press mold 52, the press mold descends On the upper face of the band 10, the storing dents 14 corresponding to the figure of the press mold 52, are formed. As shown in FIG. 3, the storing dents 14 are in a plane square shape. As the press mold 52 descends only to the midway of the thickness of the band 10, the storing dents 14 of the depth to the midway of the thickness, are formed. As the flat base 54 is applied to the lower face of the band at the time of press-forming, the swelling figure is not formed on the lower face of the band and the flat back face remains. Therefore, in the bottom portion of the storing dents 14, the thickness of the band 10 is compressed and becomes a thinly hardening condition. Compress-forming is to the extent that the thickness of the band 10 is about 0.5 mm.
The cover tape 30 is supplied on the storing dents 14 stored the little parts 20. As shown in FIG. 4, the cover tape 30 has the width a little wider than the width of the storing dents 14 and does not cover the position of the feeding holes 12 of the band 10.
The heat-bonding edge 67 of the heat seal tool 68 pushes up the cover tape 30 to the band 10 and heats and melts. For the condition of heat-bonding, the heat-bonding edge 67 is pushed up with a hundred and several tens ° C. and about one second. The heat-bonding edge 67 includes two edges along the both side edges of the cover tape 30 and, as shown in FIG. 4, heat-bonds the cover tape 30 to the band 10 outside the storing dents 14 and two linear like heat-bonded portion 32 is formed. As the cover tape 30 is transparent, the little parts 20 in the storing dents 14 can be recognized through the cover tape 30.
As shown in FIG. 6(I), if the upper die set 200 descends in the condition of arranging the band 10 above the die plate 254, the movable plate 240 touches the upper face of the band. If the upper die set 200 and the punch plate 202 descends further, the spring 242 is compressed and the pointed ends of the press mold 252 and the piercing punch 220 from the lower edge of the movable plate 240 remaining the contacting position of the movable plate 240 to the band 10. The press mold 252 is pushed in the band 10 and the storing dents 14 are formed. The piercing punch 220 pierces the feeding holes 12 to the band 10. A piercing waste 12a piercing the feeding holes 12, is exhausted from the piercing hole 256 piercing the die plate 254 and the lower die set. During this time, the movable plate 240 is pushed up to the upper face of the band 10.
As a result, as the band 10 is press-formed in the holding condition between the movable plate 340 of the upper face and the die plate 254 of the lower face, the band 10 does not easily move or change and the processing of the storing dents 14 and the feeding holes 12 is exactly performed. Moreover, as the dimension of the press mold 252 projecting downward from the movable plate 240, that is to say, the dimension of the press mold 252 pushed in the band 10 is fixed, the dimension of the storing dents 14 to the depth direction is established very exactly.
In the embodiment shown in FIG. 7, the figure of the pointed end of the press mold 252, is modified.
