Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand-layup product such as a bathtub or a shower pan, which comprises a loop-shaped production line in which instructions of work contents are made online and an offline process in which instructions of work contents are not made online. Or, it relates to a work instruction system of a molding line for molding a spray-up product.

[0002]

2. Description of the Related Art When molding hand lay-up products or spray-up products such as bathtubs and shower pans,
Depending on the type of the product, a special process such as a special gel coating resin coating operation may be required.

On the other hand, such a special process is often a process in which the instruction of the work content is not made online.
In other words, the molding of a product that requires a special process requires the process shown in FIG.
As shown in (1), a molding line in which an off-line process 2 is added to a loop-shaped production line 1 in which work content instructions are put online is used. Accordingly, the work in the off-line process 2 is different from the process in the production line 1 and is treated separately from the process in the production line 1.

On the other hand, a database has a data structure in which a model number master for identifying a type and a model master indicating characteristics of a unit are associated with each other.
However, the structure does not include the data indicating the presence / absence of the work in the offline process 2. For this reason, in the production plan creation device 32 for creating a production plan, a type group that requires the offline process 2 and a type group that does not require the offline process 2 are distinguished on a program.

[0005] In the off-line process 2, the instruction of the work content is not made online. Therefore, the site worker in the offline process 2 picks up the work content to be performed in the offline process 2 from the contents of the production plan 51 printed by the production plan creation device 32 and, based on the picked up work content, Step 2 was being performed.

[0006]

However, the above-mentioned conventional method has the following problems. That is,
The production plan creation device 32 distinguishes, on a program, a type group that requires the offline process 2 and a type group that does not require the offline process 2. Therefore, when a type is updated or a new type is registered, the database is updated, and a type group that requires the offline process 2 and a type that does not require the offline process 2 are updated based on the updated database. Both groups with the group need to be updated together. That is, in the production plan creation device 32, it is necessary to change the program for distinguishing the mold groups. Therefore, updating a mold and registering a new mold is not only a change in the database, but also a change in the program of the production plan creation device 32, which requires a lot of trouble.

[0007] The on-site worker in the offline process 2
The work contents of the off-line process 2 are retrieved from the production plan 51, and the work is performed based on the retrieved work contents. For this reason, an error may occur when picking up the work of the off-line process 2, and there is a possibility that a work error may occur. In addition, the work of picking up the work contents of the offline process 2 from the production plan 51 is a troublesome work requiring time and effort.

The present invention has been made in order to solve the above-mentioned problem, and an object of the present invention is to add a model attribute indicating the necessity and necessity of an offline process and work information to a database in which types are registered. In addition to minimizing software changes associated with type updates and new type registrations,
An object of the present invention is to provide a work instruction system that can save time and effort required for designating work contents in an offline process.

[0009]

In order to solve the above-mentioned problems, a work instruction system according to the present invention comprises a loop-shaped production line in which instructions of work contents are made online, and an offline process in which instructions of work contents are not made online. It is applied to the work instruction system of the molding line that molds the hand lay-up product or spray-up product, and indicates the molding information and the model attribute indicating whether or not the molding includes the work of the offline process. A database attached to the data for identifying the type is read from the database, and the model attribute of the type targeted for the production plan is read from the database. It is designed to print a work instruction sheet instructing the work contents of the offline process based on the model attribute. .

[0010] That is, the model attribute indicates molding information and data indicating whether or not the molding includes work in an offline process. In other words, the model attribute is data that associates the work content and the type on a one-to-one basis. Therefore, when a type is changed or a new type is registered, it is only necessary to update the database. Further, by referring to the model attribute of the mold targeted for the production plan, it becomes clear whether the work of the mold targeted for the production plan includes the work of the offline process. If an offline process is included, the work content of the offline process is printed as a work instruction. For this reason, the worker in the off-line process can easily know the work content from the work instruction document even though the work content instruction is not online.

Expand to manufacturing process level. Then, the production plan data expanded to the manufacturing process level is output to the site controller 33 via the network 6.

The on-site controller 33 controls the production line 1 based on the production plan data developed at the manufacturing process level.
, And information as shown in FIG. 6 is displayed on the screen. In addition, the on-site controller 33
Prints the work instruction 35 of the offline process 2 using the printer 34 based on the production plan data developed at the manufacturing process level.

FIG. 3 is an explanatory diagram showing the master database stored in the database 36, FIG. 4 is an explanatory diagram showing the model number database stored in the database 36, and FIG.
FIG. 4 is an explanatory diagram showing a model database stored in the database 36.

The master database 100 includes a model number 101 as data for identifying the mold 20, a model code 102 for identifying the model to be molded, and a model name 10 indicating the name of the model.
3 and a database in which the type code 104 as a model attribute is associated with each other.

The type type code 104, which is a model attribute, is data indicating whether or not the work of the off-line process 2 is included, and may be any data associating the work content with the type 20 on a one-to-one basis. In the present embodiment, as the model attribute,
"Type decoration", "Crushed stone sheet", "Direct crushed stone",
Six types of attributes, "bathtub", "multicolor", and "other" are prepared. For this reason, the type classification code 10
