Description

  The present invention relates to a used component tape discharging system for discharging a used component tape of a tape-type component supply device.

2. Description of the Related Art Conventionally, in a board unit production line, a chip-shaped electronic component (hereinafter simply referred to as a component) is held between two types of tape members that are mounted on a component mounting apparatus and have side end portions bonded together. There is a tape-type component supply device which is also called a tape feeder or simply a feeder. (For example, refer to Patent Document 1.)
The invention of the above-mentioned Patent Document 1 is an invention for automatically cutting a component tape that has been used and discharged, and shows an improved conventional tape-type component supply device as shown in FIG. 4 (b). 5 and 6 (a) and 6 (b) are shown as a conventional tape-type component supply device, and FIG. 1 is shown as an overall configuration of the tape-type component supply device according to the invention.

  4 (b) as the preceding conventional figure, the tape-type component supply device 11 drips the main body tape (accommodating tape 13-2) inside the component supply stage 8, and the upper holding tape (top tape 13- 1) shows a configuration in which 1) is wound on a reel at the top of the apparatus.

  Further, the tape-type component supply device 15 shown in FIGS. 5 and 6 (b) as an improved conventional drawing makes the main body tape (accommodating tape 28) flow down to the outside of the component supply stage 8 'for easy handling, The upper holding tape (top tape) is taken into a tape collecting container at the rear of the apparatus to facilitate replacement of the tape collecting apparatus.

  The tape-type component supply device 30 shown in FIG. 1 as the invention of Patent Document 1 has substantially the same configuration as the tape-type component supply device 15 shown in FIGS. 5 and 6 (b) of the improved conventional drawing. A device for automatically cutting the component tape flowing down outside the component supply stage 8 'is attached.

  By the way, the conventional conventional tape-type component supply device shown in FIG. 4 (b) of Patent Document 1, the improved conventional tape-type component supply device shown in FIGS. 5 and 6 (b), and FIG. In any of the tape-type component supply devices as the invention of Patent Document 1 shown in FIG. 1, there is no great difference in the discharge form of the used component tape.

  In other words, if the improvement of discharging from the inside of the component supply stage to the outside is ignored, the used main body tape is discharged in a spilling manner to the outside of the tape-type component supply device, and this is also a removable reel. If the improvement of making the box easier to attach and detach is intentionally ignored, there is no significant difference in that the top tape is collected in the tape collecting device.

  By the way, the component tape used for the tape-type component supply device is a double structure of an embossed body tape and an upper pressing tape (also referred to as a top tape or a top cover tape) in which a component housing portion is molded with a pressing mold, Or it is comprised by either the triple structure of the main body tape which consists of a perforated tape and a lower pressing tape (it is also called a bottom cover tape), and an upper pressing tape.

  In general, the embossed main body tape is slightly hard and flexible resinous, and the upper pressing tape is made of a thin resin film, and the material is resin. That is, the entire component tape is made of resin.

On the other hand, in the part tape having a triple structure, the perforated tape is made of thick and loose flexible paper, that is, pulp, the lower pressing tape is thin paper, and the upper pressing tape is made of a thin resin film. That is, the whole body tape is made of pulp, and the upper pressing tape is made of resin.
JP 2005-123465 A (paragraphs 0003-0006, FIG. 4, paragraphs 0008-0012, FIG. 5, FIG. 6, paragraph 0022, FIG. 1)

  By the way, in recent years, for the purpose of environmental protection, all waste discharged from companies is required to be disposed of separately. For those that cannot be separated and disposed of, it is necessary to spend a large amount of money and entrust disposal to a specialized disposal company as industrial waste.

  That is, if the above-mentioned used part tape is discarded as it is, it becomes an industrial waste and costs are high. Therefore, it is necessary to separate and discard the pulp material part and the resin material part in order to reduce costs.

  Then, in the case of a double-structure parts tape, the entire body is made of resin, but the main body tape drips to the outside of the tape-type parts supply device, and the upper holding tape is collected in two parts: the tape collection device. This method cannot be denied that there is a lot of waste in the time of collection.

  Further, as described above, the main body tape (perforated tape and lower pressing tape) of the triple structure component tape is made of pulp, and the main body tape (embossed type) of the double structure tape is resinous.

  And the tape-type component supply device which winds and holds these component tapes is mixedly arranged on one component supply stage, and all of the used main body tapes are tape-type. It spills outside the component feeder.

As a result, the main body tape discharged from the adjacent tape-type component supply device onto the floor of the production line is a mixture of pulp and resin main body tapes.
Therefore, when a site worker removes and discards the deposits of two types of main tapes on the production line floor, the two main tapes are separated and sorted one by one. You have to spend the effort of putting it together as a thing.

  In addition, in the case where the tape-type component supply device is a large-sized device, there is one that automatically cuts the main body tape to an appropriate length and discharges it, but in this case, it was cut shortly made of pulp and resin Since the tapes are mixed finely, the separation becomes more difficult.

  In addition, the tape deposited on the floor is often mixed with fine waste parts scattered on the floor at the time of recovery, and the work of removing these waste parts from the recovery tape is also often performed. It takes time and becomes a problem.

  In view of the above-described conventional situation, an object of the present invention is to provide a used component tape discharging system that discharges a used component tape so as to facilitate separation and disposal after collection.

  The component tape discharging system of the present invention is a used component comprising a component mounting device for mounting a chip-shaped electronic component on a printed circuit board and a tape-type component supply device for supplying the chip-shaped electronic component to the component mounting device. A tape discharge system, provided in the tape-type component supply device, provided in the component mounting device, switching means for switching the discharge route of the used component tape according to the material of the component tape to be used, and the tape And an accommodating portion for separately accommodating the used component tape discharged from the type component supply device according to the material.
