TECHNICAL FIELD

The present invention relates to a work support device and a work support method.

BACKGROUND ART

The environment for manufacturing is being changed greatly in accordance with the recent social situation. Due to an increase in overseas production, an increase in the number of products procured from overseas, and a decrease in the number of skilled technicians, it has become difficult to maintain manufacturing skills, bringing quality control into more difficult situations. To date, skills have been handed down through direct instruction from skilled technicians.

However, because a means to convey skills are not sufficient and the instruction is often sensuous, the guidance takes time or is transmitted incorrectly, and hence there is a concern that the skills may not be completely handed down and lost.

On the other hand, with the development of measurement technology in recent years, efforts have been made to measure and evaluate skills. For example, efforts are being made to measure and evaluate the work of a subject by using various measuring instruments. The measured data is compared with data measured in the past to evaluate the quality, and methods used for quality control and training of welding work have been proposed.

PTL 1 discloses a device for evaluating the skill level of an operator who needs to acquire the skill of work when hand welding is performed.

The skill evaluation result presentation device measures the state of work related to the work for which the skill to be evaluated is required, and presents, as the evaluation result, an index obtained from the result of comparing a specific significant pattern obtained from quantitative behavior data and work state data with a pattern of model data stored in a pattern storage device which stores previously established model data and information on the data range and pattern of the model data.

SUMMARY OF INVENTION

Technical Problem

Even with the same work result, the degree of fatigue and the degree of safety vary depending on the posture during work. That is, a skilled operator works in a safe and posture that hardly causes fatigue and can thus work stably for a long time. Hence it is important to learn an ideal work posture separately from the learning of the work contents, but no proposal has been made to support the learning of the work posture.

For example, it has not been possible to evaluate the posture by the method of PTL 1. That is, in PTL 1, although there is a function of indicating a posture of an operator during work, a position relative to a work target, and a standard deviation of the position, it has not been possible to determine the posture that the operator can work to stabilize the operation, perform the work with less fatigue, and the like.

Therefore, it is an object of the present invention to provide a work support system suitable for improving the work posture of an operator.

Solution to Problem

In order to solve the above problem, the work support device of the present invention has the following features:

The present invention is provided with: a storage unit that stores posture associated information associated with workability being an evaluation criterion at a time of a posture for each piece of posture information of an operator; a detection unit that acquires posture information of the operator during work as current posture information; a calculation unit that obtains, from the posture associated information, ideal posture information for improving workability of the current posture information, obtained by referring to the posture associated information in the storage unit from the current posture information, with respect to the workability; and a notification unit that notifies the ideal posture information obtained by the calculation unit as an improvement proposal.

Other means will be described later.

Advantageous Effects of Invention

According to the present invention, it is possible to provide a work support system suitable for improving the work posture of an operator.
