2. Description of the Related Art For example, in a prefabricated house, building materials produced in advance in a factory are used when building a house on a construction site. As the building material, the floor of the house,
Panels that make up walls, ceilings, roofs, etc., floors, walls,
There are units such as a ceiling assembled. In addition, in prefabricated houses, standardized building materials are used and the design of the house itself is also standardized to improve productivity, but originally the house responds to the various demands of the people who live there. It is designed by Therefore, even in prefabricated houses, a system has been proposed in which houses of various patterns can be constructed in response to individual customer requirements.

Therefore, even if the building materials used for prefabricated houses are standardized, the types of building materials will inevitably increase because the houses to be finally built differ from customer to customer. Therefore, in the production line of the factory,
It was necessary to produce a wide variety of building materials in response to customer requests. In addition, the production volume of each building material may differ significantly depending on the customer's request, so it is difficult to quickly respond to the customer's request by increasing the inventory amount, and it is possible to quickly respond to the ordered quantity. Needed to produce building materials. Producing a wide variety of building materials promptly according to the ordered quantity makes it difficult to control the production on the building material production line.

However, in the above-mentioned building material production line, it is still difficult to unmanned due to cost and technical problems, so that an automated part and a part requiring human involvement are mixed. Therefore, in the above-mentioned building material production line, it is difficult to grasp the progress of the production process in substantially real-time like a completely automated production line. Therefore, confirm the number of building materials produced on that day. As a result, the production volume for the next day was decided.

Since the production status of each production line cannot be grasped in real time and the production plan is updated on a daily basis, the operating rate of the production line and the allocation of personnel to each production line, etc. Was causing a loss. Especially when a trouble occurs in the production line, depending on the content of the trouble, the production line does not stop because the workers are involved in the work of the production line, and only the production speed decreases. In such a case, there is often a delay in responding to the trouble in the production plan, and it is necessary to make a relatively large change to the production plan when the production is continued without changing the production plan. There was a problem such as coming.

The present invention has been made in view of the above circumstances, and it is possible to grasp the production status of a production line in which an automated part and a part in which humans are involved coexist in real time and at the same time, the production speed.

In the above, there is no need for a worker or manager on site to check the production result of the panel and produce the data for checking the efficiency of the time and the staffing for the production line L, and output from the second small computer. Therefore, it is possible to deal with future production plans simply by examining the data.

Therefore, it is possible to save labor in production management work such as complicated data arrangement of production results. As described above, according to the production management system of this embodiment, it is possible to easily perform production management in the production line L in which the automated production equipment and the non-automated production equipment are mixed. The human intervention in the line L can save labor of the production management work which has been complicated.

As described above in detail, according to the production control system of the present invention, the completion signal output means is
Final line production equipment of automated production line
When a signal indicating the end of work is output from the
Production equipment in the final process of a production line that is not automated
Work by pressing the work end button provided on
Output a completion signal when a signal indicating the end is output
It In other words, the simple configuration of outputting a completion signal each time a product is completed from the production line allows the actual product production amount that increases over time to be grasped as the actual production amount, and at the start of production on the production line. Therefore, if the planned production amount is added every time the target production time elapses, the planned production amount can be used as a pacemaker. Therefore, by comparing the planned production amount with the actual production amount, it becomes easy. You can grasp the progress of production.
Therefore, it is possible to grasp the progress of production with a simple configuration that can be easily applied to a production line in which both automated and non-automated production apparatuses are mixed, and it has been difficult to control production in the past. It is possible to easily perform production management of a production line in which both automated production equipment and non-automated production equipment are mixed.

Further, since the progress can be easily grasped by comparing the planned production amount and the actual production amount, if the difference between the planned production amount and the actual production amount exceeds the allowable range, the worker or the administrator By so doing, even in a production line in which an automated production device and a non-automated production device coexist, it is possible to quickly recognize the abnormality, and to quickly respond to the abnormality in the production line. it can.
