Description

[Detailed description of the invention] The purpose of this invention is to make it easier to load a package of electronic components into an automatic insertion machine by allowing the electronic components to be pulled out without removing the spirally wound electronic component roll from the package, and to make it easier to transport and store the package.

In recent years, with the development of automatic machines, electronic component chains, in which multiple electronic components with lead wires, such as capacitors and resistors, are held at equal intervals on a strip-shaped holder such as paper tape with adhesive tape, etc., are used. The series of electronic components is spirally wound around a winding frame or a winding core, and the winding body is loaded into the parts supply section of an automatic printed circuit board insertion machine and unwound one after another. Electronic components are cut out one by one and automatically inserted into a printed circuit board.

One method of this method is to provide a through hole in a box formed by a lid, a bottom, and a side surface at opposite positions of the lid and the bottom, and insert a through hole into the central portion of the box. Both ends of a cylindrical winding core having a through hole are rotatably fitted together, and a plurality of electronic components are arranged on a band-shaped holder around the outer periphery of the winding core to form a series of electronic parts. By winding a series of parts and opening one of the side parts of the box, the series of electronic parts are sequentially pulled out from the opened part, and the rolled body of the series of electronic parts is removed from the box. Instead, it has been proposed that the package itself can be loaded into the component supply section of an automatic inserter for use. Then, such a package body is set at a predetermined position in the parts supply section of the automatic insertion machine, and
The end of the pulled out electronic component chain is guided to the sprocket via a roller, and the electronic component chain is intermittently pulled out from the package body, but at this time, if it is pulled out excessively from the outlet of the package, When the automatic insertion machine stops operating, it is necessary to rewind the series of electronic components that have been pulled out of the package into the package. A protrusion is provided at one end of the winding core to facilitate unwinding. In addition, when transporting or storing a plurality of package bodies, they are held in a stacked state, but at that time, the protrusion gets in the way and makes it difficult to stack them properly, which is inconvenient. is provided on the other end opposite to the protrusion provided on one end of the winding core.

The present invention will be explained below with reference to the drawings. FIG. 1 shows a conventional package body, and the package is composed of two parts, a main body 30 and a detachable body 31. As shown in FIG. The main body 30 includes a bottom part 5, a lid part 6,
Side parts 8, 9, 11, ears 12, 13, tongue piece 1
5. Insert pieces 18 and 32 are provided, and a notch 17 into which the insert piece 18 is inserted is provided in the ear portion 13.
The insertion piece 32 can be cut out from the perforation 33, and through holes 19 and 20 are provided approximately at the center of the bottom surface 5 and the lid surface 6. The through holes 19 and 20 have a collar portion 50.
is fixed to one end thereof, and a through hole 2c is formed in the center thereof.
The ring-shaped protrusions 2a and 2b of the winding core 2 can be rotatably fitted together. That is, the inner diameters of the through holes 19 and 20 are made slightly larger than the outer diameters of the ring-shaped protrusions 2a and 2b of the winding core 2, so that when the lid surface part 6 is closed, the ring-shaped protrusions of the winding core 2 2a and 2b are connected to the lid part 6 and bottom part 5 of the package.
It is designed to be rotatably supported from both sides. The inward edges 21, 22 of the ears 12, 13 are formed by arcs with a radius larger than the outer circumference of a wound body of a series of electronic components, as described below, to be housed in this package.

The detachable body 31 is made up of a side surface 10, a holding plate 34 and an ear 35 that are connected to the side surface 10, and when the lid surface 6 of the main body 30 is closed, the main body 30 is removed.
It is inserted into the box to form a hexahedral box. This restraining plate 34 has a notch 3 formed of a circular arc portion having a radius r larger than the outer diameter of the winding core 2 and an open portion having a width d larger than the outer diameter of the winding core.
It has 6. Reference numeral 37 is a notch provided on the main body 30 into which the insertion piece 32 is inserted, and 38 is a finger hole provided to facilitate removal of the detachable body 31.

Next, a series of electronic components to be housed in the package constructed as described above will be explained. As shown in FIG. 2, this electronic component series 1 has a plurality of electronic components 7 such as capacitors arranged in parallel at regular intervals on a strip-shaped holder 25, and leads led out from the electronic component elements in the same direction. Adhesive tape 27 on line 26
The electronic parts 7 are fixed on a holder 25 with holes 28 for feeding and positioning provided at equal intervals between the electronic parts 7. The electronic component string 1 formed in this way prevents the electronic components 7 from getting caught on each other when they are overlapped, and also prevents the electronic component string 1 wound from being caught on each other.
is wound around the hollow cylindrical winding core 2 with an isolation tape 29 sandwiched therebetween to make it into a cylindrical shape,
The collar portion 50 is also fixed to one end of the winding core 2.
is placed on top.

When loading the package body of the electronic component series 1 configured as described above into the component supply section of the automatic printed circuit board insertion machine, the insertion piece 32 is pulled out with the lid surface 6 kept closed, and the perforation 33 is removed. Then, remove the insertion piece 32, put your finger in the finger hole 38, and pull out the detachable body 31 from the main body 30.

In this package body, the upper surface of the electronic component series 1 is free because a gap is created between it and the lid surface portion 6 by the amount that the restraining plate 34 is removed, and the inward edge 2
1 and 22 are also located outside the outer peripheral surface of the wound electronic component chain 1, so the electronic component chain 1 wound around the winding core 2 can freely rotate. Moreover, the electronic component chain 1 has a collar portion 50 fixed to one end of the winding core 2.
Since the electronic component series 1 is placed on the top, the bottom surface of the electronic component series 1 does not come into contact with other components of the package and rotates almost integrally with the flange 50, which prevents damage to the electronic components. can be accurately prevented.

Now, the main body 30 of the package body from which the end of the electronic component series 1 is pulled out is inserted through the through hole 2c provided in the winding core 2, as shown in an example in FIG.
The electronic component series 1 is loaded onto the loading shaft 70 provided at a predetermined position of the component supply section 100 of the automatic printed circuit board insertion machine, and the end of the electronic component series 1 is guided to the sprocket 61 via the roller 60. The feeding and positioning hole 28 provided in the sprocket 61 is engaged with the sprocket 61. When the automatic insertion machine is operated, the electronic component series 1 is intermittently pulled out from the package by the feeding mechanism including the roller 60 and the sprocket 61, but as described above, the electronic component series 1 can rotate freely. Therefore, this drawing operation is extremely smooth.

On the other hand, if the electronic component series 1 is excessively pulled out from the outlet of the package by the feeding mechanism, or when the automatic insertion machine is stopped operating, the electronic component series 1 that has been pulled out from the package is re-wound into the package. It may be necessary to return it. In order to facilitate unwinding in such cases, a ring-shaped protrusion 2a is provided at one end of the winding core 2, as shown in the embodiment of the present invention shown in FIG. It protrudes from the surface of the hole 4, and the end can be turned directly by hand, or the hole 4 can be used as an unwinding means.
0 through which a rod can be passed and rotated. Either end of the winding core 2 may protrude from the surface.

Therefore, by manually rotating the ring-shaped projection 2a, the operator can accurately rewind the electronic component series 1, which has been pulled out, into the package. In this case, it is preferable that the electronic component series 1 be rewound into the package without the operator's hands touching the electronic component series 1, since precision is particularly required for the electronic components for automatic insertion. According to this embodiment, the operator can simply rotate the ring-shaped protrusion 2a protruding from one end of the winding core 2 around which the electronic component chain 1 is wound, without touching the electronic component chain 1. , it is possible to safely and accurately rewind the electronic component series 1 into the package.

In order to facilitate the unwinding operation, a diametrical slit is provided on the end surface of the ring-shaped protrusion 2a,
Known unwinding means such as flattening a part of the outer periphery may be used.

Further, on the opposite side of the winding core 2 to which the ring-shaped protrusion 2a is provided, there is an engagement hole 4 into which the ring-shaped protrusion 2a is fitted.
3 is provided. The dimensions of this engagement hole 43 are such that its inner diameter is such that the outer diameter of the ring-shaped protrusion 2a just fits therein, and its depth is such that the ring-shaped protrusion 2a protrudes from the surface of the lid surface 6. There is.
Therefore, when a plurality of package bodies are to be stacked, the ring-shaped protrusion 2a can be fitted exactly into the engagement hole 43 of the winding core 2 of the upper package body so that the package bodies can be stacked one after another.

FIG. 5 shows a state in which two package bodies of the present invention are stacked, and a shaft neck portion 41 is provided on the side from which the ring-shaped protrusion portion 2a of the winding core 2 is protruded.
1 fits into a through hole 20 of the lid surface part 6 and is rotatably supported, and a ring-shaped protrusion part 2a protrudes from the surface of the lid surface part 6, and has an outer diameter such that it fits into an engagement hole 43, which will be described later. ing. Ring-shaped protrusion 2b at the other end
is rotatably supported by fitting the outer diameter into the through hole 19 of the bottom surface portion 5, and has the aforementioned ring-shaped protrusion portion 2 inside.
It is provided with an engagement hole 43 having a size into which the hole a fits. The collar portion 50 is adhesively fixed to the winding core 2.

Since the present invention is constructed in this way, when a plurality of package bodies are stacked, the ring-shaped protrusion 2a and the engagement hole 43 fit together as shown in part A (numerals are omitted to avoid complexity). Therefore, during storage or transportation, a large number of package bodies can be stacked on top of each other without shifting laterally or collapsing, and handling becomes stable and easy.

Further, when applied to the component supply section 100 as shown in FIG. 3, when the package bodies are arranged closely together, the ring-shaped protrusion 2a and the engagement hole 43 are fitted in sequence. There is no need to pass all the package bodies through the through hole 2c and the fixing shaft 70, and it is sufficient to fix only the package bodies at both ends, making handling easier.

As described above, the present invention is not limited to the above-mentioned embodiments, and various modifications can be made without departing from the technical idea thereof. For example, the position of the flange portion fixed to the winding core is not limited to that shown in FIG. 4, and the shape thereof may be substantially any shape capable of mounting a series of electronic components. Furthermore, the ends of the series of electronic components wound around the winding core may be attached to the winding core, or slits may be provided in the winding core and the ends may be fixed to the slits. Of course, it is also possible to simply wind the winding. You can also just eat it alone.
