Abstract

PURPOSE:To enable the high speed discharge of a scrap tape from the outlet part of a cylindrical body by providing a nozzle between the inlet part and outlet part of the cylindrical body. CONSTITUTION:Compressed air is injected toward the outlet part 4b of a cylindrical body 4 by a nozzle 5 provided between the inlet part 4a and outlet part 4b of the cylindrical body 4. A scrap tape is thereby sucked and discharged from the outlet part 4b of the cylindrical body 4.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention mainly involves rewinding scrap tape from parts cassettes for chipping machines from parts cassettes (reels), and sometimes even general long scrap tapes by compressed air. To provide a scrap tape collection device which can easily and quickly collect scrap tape and store it in a trash can.

[Summary of the invention]

The scrap tape recovery device of the present invention includes a cylindrical body having an inlet for introducing the scrap tape and an outlet for discharging the tape, and a nozzle provided between the inlet and the outlet. By injecting compressed air from a nozzle to an outlet part, the scrap tape is discharged from the outlet part at high speed, and the scrap tape can be quickly and easily disposed of in a trash can.

[Prior art] Currently, after chip parts are mounted on a printed circuit board or the like using a chip machine, empty scrap tape with no parts attached is rewound into a parts cassette and removed from the parts cassette, and then placed in a trash can. The common method is to dispose of waste in the garbage, but up until now, this has been done manually. When chip components are mounted in mass production, it is necessary to remove hundreds of pieces of scrap tape from parts cassettes a day, which not only causes serious physical fatigue for workers, but also The time required for removal has become impossible to ignore.

Therefore, a scrap tape recovery device as shown in FIG. 3 has recently been proposed. This conventional device utilizes a commercially available or custom-made vacuum cleaner 11. In FIG. 3, 1 is a parts cassette and 2 is a scrap tape. The scrap tape 2 wound around the parts cassette 1 is suctioned and removed by a vacuum cleaner 11, and collected into a vacuum cleaner 11.

When I used this vacuum cleaner II, it became a little easier and the work time was shortened. However, there is still a lot of manual work involved, and in addition, in order to prevent the suction ability from decreasing, the scrap tape that has accumulated inside the vacuum cleaner
It became necessary to constantly discharge the waste. Furthermore, when attempting to increase the negative layer suction ability, noise and heat generation of the vacuum cleaner 11 became a problem.

[Problem to be solved by the invention]

The present invention has been made in order to solve these conventional problems, and mainly involves unwinding the scrap tape of a parts cassette for a chip machine from the parts cassette, and occasionally unwinding the scrap tape of a general long scrap tape. Although there are cases where the scrap tape remains intact, the object of the present invention is to provide a scrap tape collection device that uses compressed air to easily and quickly collect the scrap tape and to collect it in a trash can.

[Means to solve the problem]

The scrap tape recovery device of the present invention includes a cylindrical body provided with an inlet for guiding and introducing scrap tape and an outlet for discharging the scrap tape, and a space between the inlet and the outlet of the cylindrical body. A nozzle provided between the inlet and the outlet of the cylindrical body injects compressed air toward the outlet of the cylindrical body,
The scrap tape is sucked in and discharged from the outlet of the cylindrical body, and in the scrap tape recovery device, the scrap tape is wound around a parts cassette for a chip machine. Features.

[Effect]

In this way, by injecting compressed air toward the outlet of the cylindrical body through the nozzle provided between the inlet and outlet of the cylindrical body, scrap tape can be discharged from the outlet at high speed. do it like this.

〔Example〕

Hereinafter, one embodiment of the scrap tape recovery device of the present invention will be described with reference to FIG. 1, and another embodiment with reference to FIG. 2.

As shown in FIG. 1, the recovery device of the present invention mounts chip components on a printed circuit board using a chip machine, and then uses an empty scrap tape 2 with no parts attached, which is wound around a parts cassette 1, to collect the parts. This device is designed to unwind and remove the tape from a cassette 1 and discard it in a trash can 3, and can be disposed of quickly with a simple configuration.

That is, the recovery device of the present invention is mainly configured with the cylindrical body 4. This cylindrical body 4 consists of an inlet part 4a that guides and introduces the scrap tape 1, and an outlet part 4b that discharges the scrap tape 1 into the trash can 3. This inlet part 4a has a funnel shape with a large opening upward. Both are arranged substantially perpendicularly together with the cylindrical outlet portion 4b.

A nozzle 5 is provided between the inlet portion 4a and the outlet portion 4b of the cylindrical body 4, and compressed air 6 is injected from the nozzle 5. The direction in which this compressed air 6 is injected is toward the outlet portion 4b of the cylindrical body 4.

When the scrap tape 2 is pulled out from the parts cassette 1 and its tip enters the entrance portion 4a of the cylindrical body 4,
The scrap tape 2 is drawn to the vicinity of the center of the cylindrical body 4 by the negative pressure 7 created by the injection of the compressed air 6. From there, the scrap tape 2 is rapidly sucked out toward the outlet portion 4b by the compressed air 6 that is vigorously jetted from the nozzle 5, and is discharged into the trash can 3 from the outlet portion 4b.

The scrap tape 2 is discharged until the parts cassette 1 is empty, but the time required for this is short.
Collection is fast and prompt.

Another embodiment of the recovery device of the present invention will be described with reference to FIG. Note that the attached symbols are the same as in FIG. 1. The difference is that the inlet portion 4a of the cylindrical body 4 is cylindrical, pointing slightly upwards from the horizontal, and the nozzle 5 is vertical.
The point is that compressed air 6 is injected approximately straight from this nozzle 5 to the outlet portion 4b of the cylindrical body 4.

In this way, the artificial part 4a of the cylindrical body 4 is arranged approximately horizontally so that a worker sitting on a chair can easily insert the tip of the scrap tape 1 into the entrance part 4a. This is due to the consideration given to the above, but there is no change in function or effect.

Above, we have explained the example of discarding the empty scrap tape 1 that has been wound up into the parts cassette 1 and has no parts attached to it in the trash can 3. By putting the scrap tape 1 into the inlet part 4a of the body 4, it is possible to discharge the scrap tape 1 from the outlet part 4b and throw it into the trash can 3.

〔Effect of the invention〕

As described above, the scrap tape recovery device of the present invention has the following features:
It is composed of a cylindrical body having an inlet part for guiding and introducing the scrap tape and an outlet part for discharging the scrap tape, and a nozzle provided between the inlet part and the outlet part of this cylindrical body, By injecting compressed air toward the outlet of the cylindrical body through a nozzle provided between the inlet and outlet of the cylindrical body, the scrap tape can be discharged from the outlet at high speed. Moreover, it is possible to easily dispose of scrap tape in a trash can.
