DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing a human error so that an operator can perform one or more operations without fail.

[0002]

2. Description of the Related Art For example, the addition of additives and auxiliaries at the time of paint production plays an important role in that the quality of a product is greatly influenced by a small amount. Have difficulty. For this reason, if there is an error in the addition operation, it is almost impossible to investigate the operation error, although the quality of the product is greatly impaired. Therefore, it is extremely important that the addition operation be performed without errors.

It is important to increase the worker's attention in work management, but this alone does not provide sufficient work certainty. Therefore, there has been a long-felt need for a work management system that minimizes the occurrence of work errors or close to it.

[0004] As described above, prevention of human error such as an operation error by an operator has become an extremely important issue in many fields as the technology becomes more sophisticated and complicated.

[0005]

The object of the present invention is to solve the above has been made to not respond to these requests, to provide a work management method that can be kept to a degree close to nil or in the human error such as operational error There is .

The object of the present invention relates to an operation for adding raw materials.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of the present invention applied to a coating preparation process.

FIG. 1 is a schematic view of the process, and FIGS. 2 and 3 are flowcharts thereof.

First, based on a production plan, work information for preparing a paint such as an additive name, an addition amount, a charging destination tank name, and an addition order is determined (in addition, depending on a process, resin varnish, solvent, etc.). , Pigment, etc. are also used as work information).

The work information is presented to the worker as a work sheet 1 readable by the worker and a work instruction barcode 2 in a barcode format. Work instruction barcode 2
Is attached to the work slip 1. However, both may be output at once by a page printer or the like. Further, a bar code 3 indicating the additive is attached to the container 4 containing the additive in advance.

An operator selects a predetermined additive according to the work slip 1, and causes the bar code reader 5 to read the work instruction bar code of the work slip and the bar code 3 of the additive-containing container on the spot.

The reading results of both barcodes are sent to the work management computer A in the manufacturing department and collated. An audio signal is emitted from the speaker according to the suitability of the matching result,
The operator can immediately know whether or not the selection of the additive is appropriate, and when the selection is incorrect, the correct one is selected again.

Next, the worker transfers the selected additive by a predetermined amount to the raw material transport container 7 and measures it with the measuring device 8. The weighing result is sent to the work management computer and compared with the information from the work instruction barcode that has already been sent.

The work management computer displays, based on the comparison, whether the measured value is appropriate or not, and informs the operator immediately. The operator completes the weighing in the correct range by correcting excess or deficiency. When there are a plurality of additives, the above steps from selection of additives to measurement are repeated according to the number of additives.

When the measurement of the predetermined additive is completed, the operator inputs a measurement end signal to the work management computer. Thereby, the work management computer outputs the weighing label 10 through the printer 9 in the weighing work station.
The weighing label 10 is output for each additive, and the weighing result of each additive is displayed as a character and a bar code 11 based on the data of the additive name and the destination tank name based on the information on the work slip and the data from the measuring device. Have been.

An operator attaches the measuring label 10 to each raw material transport container 7. Explicit working management computer A also, the output of the weighing label 10 sends a signal to the additive to indicator 13 installed in the vicinity of the tank 12 to be turned on, the lamp 13 ₀ is turned, the submission destination to the operator I do.

The operator carries the material transfer vessel up to the tank equipped with a lamp 13 _0, where it again read the work instruction bar code 2 with the bar code reader 14. Thus, the working management computer A sends a signal to the indicator 13, the lamp 13 ₀ off, to light the lamp 13a for displaying the "Start".

Next, the operator reads the barcode 11 of the weighing label attached to the raw material transport container with the barcode reader 14. The read information and the read information of the work instruction barcode are collated by the work management computer A. If the collation result is inappropriate, a signal to that effect is displayed, and the operator optimizes the material transport container to be picked up.

If the collation result is appropriate, the display lamp is changed to "input waiting" display 13b in response to a command from the work management computer. The operator puts the additive into the tank 12 from the transport container 7 based on this. After the input, the operator presses the work end button.

As a result, the work management computer searches for the presence or absence of another unfinished compounding work, and if there is any unfinished compounding work, the indicator light 13 changes to the display 13c of "unfinished". When there is no unfinished work, the indicator light 13 is turned off. This completes the compounding operation.

The above operations are performed for each required tank, and when a predetermined number of compounding operations are completed, the compounding histories stored in the operation management computer can be output together. As a result, work results can be output on a daily or monthly basis.

The present invention can take various other forms. Hereinafter, a simple form will be described by taking the preparation of a paint as an example.

When there are many kinds of additives to be put into a predetermined tank, the worker can read a work sheet enumerating the additive names and a work instruction barcode indicating the additive names in a barcode format. To provide. A bar code indicating the additive is attached to the container containing the additive in advance.

The operator causes the work instruction bar code to be read by a bar code reader before starting the operation of selecting the additive. The information is sent to the work management computer. Next, the operator selects an additive according to the work sheet, and causes the barcode reader to read the barcode of the container containing the additive. The barcode information of the container is also sent to the work management computer, and is compared with the information of the work instruction barcode already sent.

A signal is output from the speaker in accordance with the suitability of the collation result, and the operator can immediately know whether or not the selection of the additive is appropriate. If the selection is incorrect, the correct one is selected again.

Thereafter, the operator selects the next additive and causes the same to read the bar code of the container, and the operation management computer performs collation and displays the result. In this way,
The appropriateness of the selection of various additives can be promptly and objectively confirmed each time by using a barcode, so that selection errors can be reliably prevented.

[0028] In addition, the present method is applicable to the production of chemical products such as synthetic rubber, ink and synthetic resin, the production of pharmaceuticals or cosmetics,
It can be applied to a wide range of fields such as food processing.

[0029]
