It is possible to more easily discriminate between the non-defective product and the defective product.

In the above embodiment, the non-defective label (L) is attached only to the case (C) in which the non-defective disc (D) is accommodated, but only in the case where the defective disc is accommodated. Defective product labels may be attached, and in addition, a good product label may be attached to a case containing a good product, and a defective product label may be attached to a case containing a defective product. Further, the quality is determined by attaching a label, but the present invention is not limited to this. For example, the quality can be identified by applying a paint or the like to the good case or the bad case. Good.

Further, in the above embodiment, the identification mark is provided before the disc is housed in the case, but the identification mark may be provided after the disc is housed in the case.

In the above embodiment, in the empty case transfer device (6), the empty cases (C) sequentially transferred to the empty case discharge section (23) are directly transferred to the empty case supply section (31). However, the present invention is not limited to this, and the empty cases (C) sequentially conveyed to the empty case discharge part (23) are stocked at a predetermined location, and the empty case (C) is empty from the stock location. You may comprise so that it may supply to a supply part (31) one by one.

Further, in the above embodiment, the loading mechanism conveys two discs in parallel, but even if the discs are conveyed one by one, further three discs or more are conveyed. May be.

Further, the sorting tables (35a) (35
The arrangement positions of the case for accommodating the non-defective disc and the case for accommodating the defective disc in b) are not limited to those in the above-mentioned embodiment, and may be appropriately changed. .

As described above, according to the work inspection equipment of the present invention, the discharge side case stocker is arranged near the case discharge portion of the unloading mechanism, and the case discharged from the case discharge portion is transferred to the discharge side. Since the loading device sequentially stocks the discharge-side case stocker, the operator does not need to take out the case until the discharge-side case stocker is full of cases, which reduces the work load on the worker. As a result, the effect that the work efficiency can be improved can be obtained.

In the work inspection equipment of the present invention,
Further, when adopting a configuration in which the supply side case stocker, the supply side transfer device, and the empty case transfer device are provided, the case is transferred from the supply side case stocker in which a plurality of cases with workpieces are stocked to the supply side case. Since the mounting device sequentially supplies the case to the case supply section, the operator does not need to perform the case supply operation until the case disappears from the supply side case stocker, and the empty case discharge section of the loading mechanism discharges the empty case. The case is automatically transferred to the empty case supply section of the unloading mechanism by the empty case transfer device, so the empty case is collected to the empty case supply section of the unloading mechanism in addition to the empty case collection work at the empty case discharge section. Since there is no need to carry out work, the burden on the worker is reduced in this respect as well, and work efficiency is further improved. There is an advantage in that it is Rukoto.

In the case where the unloading mechanism is provided with a mark giving means for giving an identification mark for identifying the quality of the accommodated work to the case, the case is identified by the identification mark. There is an advantage that the quality of the work accommodated in can be easily and accurately determined. As a result, it is possible to prevent the case containing the defective work from being mixed in the case containing the good work, and it is possible to reliably prevent outflow of harmful defective work.
