Description

[Detailed description of the invention] [Industrial application field] The present invention adheres electronic components between a backing tape and an adhesive tape, and automatically tapes electronic components with simple creases in advance for each crease. This invention relates to an automatic folding device for taped electronic components, which folds the electronic components by folding them back.

[Conventional example] For example, when an electronic component such as an electrolytic capacitor is supplied to an automated device configured to automatically insert the electronic component into a mounting hole formed in a printed wiring board, the electronic component is supplied to an automated device as shown in FIG. It is common practice to attach the lead wires of the electronic component 16 between the mount tape 17 and the adhesive tape 18, and then supply the tape [A] which has been taped. The apparatus for manufacturing such tape [A] is disclosed in Japanese Patent Application No. 53-73726 (Japanese Patent Application No. 58-56248).
No.) There is a device for taping capacitors.

By the way, in the tape [A], numerals 19 are folds formed during the taping process, and the folds 19 are formed at regular intervals (every predetermined number of electronic components). An example of an apparatus for forming the fold line 19 is disclosed in Japanese Utility Model Application Publication No. 141342/1988 titled ``Taping Apparatus for Electronic Components''.

[Problem to be solved by the invention] When placing the tape [A], which is a taping component with such folds 19, into a storage box, conventionally it was manually folded back at each fold 19, which required a large amount of man-hours. It was expensive. Furthermore, as disclosed in the above-mentioned Utility Model Application Publication No. 53-141342, it is known that the tape [A] is folded into a storage box using its own weight; It had the disadvantage that it could not be folded correctly for use and would spill out of the storage box. However, in view of the above-mentioned problems, the present invention provides an automatic folding device for taping electronic components, which mechanically and forcibly folds the tape [A] with creases 19 produced by an automated taping device. It provides:

[Means for Solving the Problems] In providing an automatic folding device for taped electronic components, the present invention provides a guide for regulating the running of the tape [A] fed out by a feeding roller. A curved portion is formed in the tape [A] after passing through, and the state of the curve is detected and the tape pressing member is alternately driven in an arc shape, and the tape [A] is folded back at the crease 19. It is designed to be foldable.

[Example] First, the configuration of an apparatus according to the present invention will be explained based on FIG. 1.

Reference numeral 1 denotes a pair of rollers that sequentially feed out the tape [A] described above. Behind the feed roller 1, a U-shaped box-shaped frame body 2 is arranged, in which left and right side plates 3 for regulating the folded edges of the tape [A] are integrally formed. A pair of tape guides 1 are provided on the front end side of the frame body 2, that is, on the roller 1 side.
4, 15 are provided, and tape guides 14, 1 are provided.
A cut groove is formed at the rear end of the tape guide 5, and detection switches 12 and 13 such as micro switches whose contact levers are led out through the cut groove are provided near the tape guides 14 and 15. On the back surface of the frame body 2 behind the tape guides 14 and 15, an arm 7 is provided approximately at the center thereof and is rotatable alternately about a shaft 6. At both ends of the arm 7 are shaft members 8, which serve as pressing members for pressing the tape [A].
9 is provided, and these shaft members 8, 9 are attached to the frame 2 with a shaft 6.
They are positioned so as to protrude from arc-shaped grooves 10 and 11, respectively, which are provided around the center. Further, near the rear ends of the grooves 10 and 11 formed in the frame 2, the folded end of the tape [A] is easily received in the folding direction, but due to the elasticity of the tape [A] Stoppers 5, 5' are provided to prevent this. As shown in the figure, the stoppers 5, 5' consist of retractable springs or lever members projecting into a substantially triangular shape. Further, on the rear end side of the frame 2, a slidable holder 4 made of a weight or the like having appropriate frictional properties is provided in order to hold down the folded tape [A].

Next, the folding operation of the automatic folding device of the present invention having such a configuration will be explained.

The tape [A] runs from between the feed rollers 1 and 1 to the frame 2.
The tape is continuously introduced between the tape guides 14 and 15. First, when introducing the tape [A], the shaft member 8 or 9 forming the pressing member is moved forward (roller 1
The guide 1 is placed so that there is slack (curvature) on the side located on the shaft member 8 side in the case shown.
Guide the tape [A] between 4 and 15. When the tape [A] is fed out and its curvature exceeds a certain value, the contact lever of one of the detection switches 13 mechanically detects this curvature. The arm 7 is driven by a detection signal from the detection switch 13 by a drive device (not shown). As a result,
Since the shaft member 8 is pulled down backwards (toward the cradle 4 side), fold the end of the tape [A] located between the stopper 5 and the shaft member 8 by pressing and bending it along the crease 19. It turns out. At this time, the end of the tape [A] is fed into the pedestal 4 side while resisting the repulsive force of the stopper 5. On the other hand, the shaft member 9 is moved forward, but the coaxial member 9
The folded end of the side tape [A] is prevented from returning due to its repulsive force by a stopper 5'. Further, when the tape [A] is continuously fed by the feed roller 1, the tape [A] slacks in the direction of the shaft member 9, causing a curve. This curvature is detected by the contact lever of the other detection switch 12. Therefore, as described above, the arm 7 is driven in the opposite direction by the drive device (not shown), and the shaft member 9 is pulled down. This shaft member 9
As a result, the end of the tape [A] is fed into the pedestal 4 side while resisting the repulsive force of the stopper 5', and is folded. Thereafter, by repeating the above operations, the long tape [A] is continuously folded based on the pre-formed creases 19.

[Effects of the invention] According to the invention described above, the tape, which is a taping component having creases, is mechanically and forcibly folded alternately along the creases, which was conventionally done manually. It can eliminate work and greatly contribute to improving productivity.
