Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mold-balancing-device monitoring system capable of transmitting and receiving mold-balancing-device operating information to and from a remote communication network remote from a work site.

[0002]

2. Description of the Related Art At present, labor saving is progressing in a foundry. Therefore, for such labor-saving equipment,
There is a demand to grasp how a mold balancing device used for taking out a cast product is actually operated.

[0003]

However, in the conventional mold dispersing apparatus, data relating to long-term operation cannot be accumulated and grasped. For this reason, no information was obtained on how the mold balancing device is operated on a daily basis. Therefore, conventionally, the production management of the castings ordered is not performed by monitoring the operation of the mold balancing device itself, but by a production management system operated separately from the mold balancing device. In addition, in the current mold dispersing apparatus, it is necessary to use a mold or a dispersing apparatus that is difficult to process because the properties of the mold conveyed to the apparatus (molds left for a considerable time after pouring, unpoured molds, etc.) cannot be grasped. In some cases, it was possible to process even a missing template.

[0004] Further, information on the regular or preventive maintenance of the mold dispenser is also provided on a daily basis.
Since there is no accumulation of data, it has been insufficient to improve maintenance, such as, for example, performing excessive repairs or operating the mold dispenser until it is stopped due to a failure, which eventually results in poor efficiency. As described above, the foundry needs information on the operation of the mold balancing device.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a mold-balancing-device monitoring system that monitors the mold-balancing device at least at the time of operation and transmits the operation information to a remote location. Aim.
