It was input and the result was electrically collated with the predetermined signboard rope type stored in the programmable controller in the operation panel to make a correctness judgment.

[0003]

However, according to this conventional method, when the operator thinks that the rope type is the predetermined rope type or bobbin type, the operator can make a confirmation input with the wrong rope type or shift the selection switch. There was a problem that human error such as specifying an incorrect shift position when specifying the position could not be completely eliminated.

For this reason, once the erroneous core wire is used for molding and encapsulation, a great deal of labor is required for detection and confirmation in the subsequent process, which is costly, and the risk of defective outflow can be eliminated. Absent. Further, in this preparatory work as well, the frequency of selecting such rope types and changing the setup in response to the production of a wide variety of small quantities continues to increase, and there has been a demand for improvement of the preparatory system.

As described above, it is an object of the present invention to prepare a predetermined core wire to be spirally wound as a tensile body between a canvas layer and a rubber layer in forming a belt without mistakenly making a mistake in different core wires. An object of the present invention is to provide a simple correct / wrong determination system for a predetermined rope type, which can eliminate a mistake in advance.

[0006]

In order to solve the above-mentioned problems, that is, in the core wire preparation system for forming a transmission belt according to claim 1 of the present application, the outer peripheral surface of the cylindrical forming drum is covered with a canvas layer or a rubber layer. In a system in which a core wire bobbin is set up by a transmission belt forming line in which core wires are spirally wound and laminated, the presence of the core wire bobbin mounted on the rack of the core wire bobbin is detected. Bobbin enrollment detection means, bar code reading means for reading a bar code attached to the core wire bobbin, and correctness determination to determine whether the data of the read bar code matches the core wire data instructed to be formed. It is characterized by comprising means and alarm stopping means for issuing an alarm when the determination result is erroneous and when the presence of the bobbin is not detected.

According to the first aspect of the present invention, when the bobbin around which the predetermined core wire wound in the forming operation of the transmission belt is instructed is placed on the stand and prepared, the bobbin is attached to the bobbin prepared for placement. If it is possible to determine whether or not the read value matches the instructed core wire bobbin by using the bar code, the alarm is stopped, and the core wire can be replaced without fail.

In the core wire preparation system for forming a power transmission belt according to claim 2 of the present application, in the configuration of claim 1, the correctness determining means includes the core wire data for which molding is instructed, and the core wire placed on the rack. While the bar code of the bobbin is read and the read data is stored, the read data can be compared with the stored data.

According to the second aspect of the present invention, the bar code attached to the bobbin can be read and input by a hand while the core bobbin is placed on the bobbin mount, and the read core bobbin can be used. When removed from the gantry, the bobbin detection means detects it, an alarm can be stopped to stop the progress of the process and prompt another read input, and the barcode of the core bobbin placed on the gantry can be used once when the bobbin is installed. It is now possible to build a system that can always read barcodes on the loading bobbin without having to constantly read in real time during loading.

(S26) to complete the replacement of the core bobbin B, that is, the setup replacement.

Next, the spinning molding operation stage will be described with reference to FIG. After the molding condition setting stage (S1) is completed, the molding condition setting is completed (S18), the rope has been correctly set up for a predetermined rope type, and the present invention is in the process of being laminated with a canvas, a rubber sheet or the like. The push button PB is turned on (S30) to start the spinning of spirally winding the core wire S which is the tensile body related to the above.

After spinning starts, rope type = correct / wrong? In the monitoring state of (S31), spinning is performed (S32) in which the core wire is spirally wound around the outer periphery of the molding die while securing the correct rope type as instructed.

During the spinning operation, is the rope remaining amount in the rope bobbin emptied or not?
(S33) Monitoring is performed, and if there is a rope, further traverse of rope = incomplete / completed? (S34) When the rope traverse is completed after monitoring, the memory of the instruction rope type is automatically cleared (S35) and one molding cycle is completed.

For the above normal flow, rope type = positive /
A mistake? In (S31), if an erroneous determination is made, the spinning is automatically suspended (S38), the buzzer and the alarm lamp are activated and an alarm (S39) is issued, the rope is replaced (S40), and the core bobbin stand is reached. The core bobbin B1 placed on 50B is switched to the standby state. At this time, when there are many standby bobbins B1 or none, the bobbins are replaced as described above.

Also, the remaining amount of rope = Yes / No? (S33) If the rope runs out during monitoring, replace the rope in the same way as above (S33).
40) is performed, the process returns to in the flow chart, and the push button PB for restarting spinning is turned on (S30).

In this way, in the rope bobbin exchange, in addition to changing the product type, the remaining amount of the core wire of the bobbin being consumed becomes empty,
