System for preventing long mold defects in tire production process {SYSTEM FOR PREVENTING WRONG MOLD FAULTS IN TIRE MANUFACTURE LINE}

The present invention relates to a system for preventing long mold (WM) failure in the tire production process, and more particularly to a system for preventing long mold failure in the tire production process managed by the process management server. will be.

Long mold defects are defects caused by molded tires, for example, green tires, which are vulcanized in molds of different specifications in the vulcanization process. Occurs when misdelivery occurs. In the past, when a WM defect occurred, it was visually identified.

In the past, the verification of the occurrence of WM defects can be performed by visually checking whether there is an excessive extraction in the appearance of the vulcanized finished tire, or visually confirming the molded tire through the printing type printed on the tread. In addition, it was made by visually confirming the vulcanization specification with the type stamped on the tire through the mold.

The verification of the existing WM defects was performed in the vulcanization process by comparing with the mold specifications currently in the vulcanizer, in the inspection process by inspecting the tire appearance, loading the tires at the time of shipment, and in the distribution center. It was performed at the time of getting off at the distribution center and at the time of loading at the dealership.

The verification of such existing WM defects is not a measure for preventing WM defects, but a passive countermeasure found after death. In addition, there is also a problem that the reliability of the failure prevention is poor because the visual inspection is performed depending on the ability of the person. In addition, it is necessary to print the standard information on the tread because it is necessary to check the specification information of the tire with the naked eye, and the necessity for deleting the tread type printing is increasing due to the bleeding of the tread type and the deterioration of the tire blackness. .

An object of the present invention is to provide an automatic system that can prevent 100% of WM defects in advance. In addition, it aims to suggest a way to replace the tread type for improving the emotional quality.

The present invention relates to a system for preventing long mold defects in a tire production process managed by a process management server. In order to achieve the above object, a system for preventing long mold defects according to the present invention comprises: a first computer for monitoring and controlling a tire former and a tire ejector; And a barcode attaching device for attaching a serial barcode generated on the basis of tire specification information including molding specification information to the tire, wherein the first computer stores the molding specification information for the tire being molded by the tire molding machine. 1 memory; And a second memory for storing molding specification information for the tire in which the molding is completed in the tire forming machine, and when the tire is passed from the tire forming machine to the tire ejector, the first computer sends the molding specification information stored in the first memory to the serial bar code. The value is copied to the second memory using the identification number, and the process management server receives the molding specification information together with the identification number from the second memory. Furthermore, the tire feeder may receive molding specification information from the second memory together with the identification number.

According to an embodiment of the present invention, a system according to the present invention comprises: a second computer for monitoring and controlling a tire delimiter; And a bar code scanner for recognizing the serial bar code of the tire before the tire is put into the tire vulcanizer, wherein the second computer includes the tire vulcanized according to the molding specification information corresponding to the serial bar code recognized by the bar code scanner. It can be determined whether or not it can be added to the device. Further, the second computer includes a third memory that stores a matching table that matches a specification for which a particular molding specification can be vulcanized, and the second computer uses the matching table to determine whether the tire can be put into the tire delimiter. You can decide.

According to the present invention, the WM defect can be prevented 100% in advance to reduce the cost due to quality deterioration. In addition, in the present invention, since the recognition of the specification through the tread type is changed to the recognition through the bar code, it is possible to reduce the cost of paint and the performance of the paint work. Furthermore, the emotional quality can be improved by deleting the tread type.

2 is a view for schematically explaining a molding process according to the present invention.
3 is a diagram illustrating a matching relationship of a matching table according to the present invention.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

1 is a view for schematically illustrating a system for preventing a long mold failure according to the present invention, Figure 2 is a view for schematically illustrating a molding process according to the present invention.

As shown in FIG. 1, a tire, such as a green tire, formed in the tire forming machine 210 is drawn out by the tire ejector 220 and placed in the tire number 230, and subsequently by the tire feeder 240. In a later process, for example, it is transferred to the tire vulcanizer 250.

The system for preventing a long mold failure according to an embodiment of the present invention, as shown in Figure 1, a tire including the first computer 110 and molding specification information for monitoring and controlling the tire molding machine and tire ejector And a barcode attaching device (120) for attaching a serial barcode generated based on the specification information to a tire, wherein the first computer (110) includes: a first memory for storing molding specification information of a tire being molded by a tire molding machine ( 111) and a second memory 112 for storing molding specification information about the tire of which the molding is completed in the tire molding machine.

The barcode attachment device 120 is a device that attaches tire specification information to a tire, for example, a bead portion of a tire, in a serial barcode format. The bar code attachment device is for replacing tire tread type using a serial bar code, and the serial bar code is generated based on tire specification information such as tire shaping specification information, vulcanization specification information, work information, or any combination thereof. Can be. For example, when the value of the serial barcode is 12345678, the serial barcode may include molding specification information and vulcanization specification information.

The molding process, as shown in Figure 2, the tire forming step (S201), the bar code attaching step (S202), the step of transporting the tire to the post-process (S203), and the step of transferring the molding specification information to the process management server (S204). Conventionally, in the molding process, when there is a mismatch between the actual molding specification and the molding specification information transmitted to the process management server (MES), a WM defect occurs. In other words, when an operator replaces the molding specification in S201 to S204, a WM defect occurs. Since the molding of the other language is completed, the specification replacement is performed before the molding specification information is transmitted to the process management server. WM defects occurred because the actual molding specification for the tire placed in the dispenser and the operator changed the molding specification to the molding specification information transmitted to the process management server. Therefore, the WM defect occurred because the process management server misinterpreted the tire placed in the machine in a molding standard different from the actual molding standard.

In order to solve this problem, in the present invention, the first computer 110 stores the molding specification information for the tire being molded in the tire molding machine and the molding specification information for the tire which has been molded in the tire molding machine. It was configured to include a second memory 112 to store, so that the molding specification information of the tire being molded and the molding specification information of the completed tire are managed and stored separately. In addition, the time point at which the second memory 112 is updated is determined as the time point at which the tire is completed in the tire forming machine and is transferred to the tire ejector. In other words, when the tire is passed from the tire molding machine to the tire ejector, the first computer copies the molding specification information stored in the first memory to the second memory using the serial barcode value as the identification number. Thereafter, the process management server receives the molding specification information together with the identification number from the second memory. Furthermore, the tire feeder for transferring the tire from the tire extractor may also receive molding specification information from the second memory together with the identification number.

By such a configuration, even if the operator changes the molding specification information of the molding machine for changing the specifications, the molding specification information of the tire in the ejector is not affected. In addition, since the molding specification information of each tire is managed using the value of the serial barcode attached to the tire as an identification number, the serial barcode is recognized when the molded tire is used in any next process or transported to any other process. To determine whether it is suitable for the process. Furthermore, the tire extractor and the tire feeder, which are conventionally operated depending on the tire molding machine, may be operated independently of the tire molding machine.

In the vulcanization process, if the operator does not confirm the specification information, for example, the molding specification information before the vulcanization, WM defects occur, or if the operator does not confirm this even though the WM defects occur, the WM defective tire is moved to a post-process after the vulcanization process. This WM defect is caused by the carelessness of the worker who did not check the specifications correctly when the tires were manually inserted, and when the tires were inserted by automatic transportation, error correction of computerized data, conveyor, or automatic logistics equipment was taken. It is due to inadequate.

In order to solve this problem, a system for preventing a long mold failure according to an embodiment of the present invention, as shown in Figure 1, the second computer 130 for monitoring and controlling the tire delimiter; And a bar code scanner 140 for recognizing the serial bar code of the tire before the tire is put into the tire vulcanizer may further include.

The second computer may determine whether the tire is insertable into the tire garbator based on the molding specification information corresponding to the serial barcode recognized by the barcode scanner. In other words, in the present invention, before the tire is put into the vulcanizer, the serial barcode is recognized and the molding specification is extracted. In the case of automatic feeding, for example, an automatic barcode scanner is installed on the conveyor before the vulcanizer is put in and the serial barcode is attached to the tire. In the case of manual input, the operator can recognize the barcode manually by using a handy scanner (Handy Scanner).

3 is a diagram exemplarily illustrating a matching relationship of a matching table according to the present invention. The matching table is a table that defines what specifications a particular molding specification can be vulcanized. FIG. 3 shows that N molding specifications are matched with M vulcanization specifications. More than one vulcanization specification can be matched for one molding specification. Such a matching table can be prepared in advance before the entire tire production process begins.

According to a further embodiment of the present invention, the second computer includes a third memory 131 storing a matching table that matches a specification in which a specific molding specification can be vulcanized, and the second computer is recognized by a barcode scanner. Based on the molding specification information corresponding to the serial bar code, the matching table can be used to determine whether the tire can be put into the tire vulcanizer. The second computer may include computer readable software running on the second computer to make this determination.

In other words, the second computer can obtain the molding specification information of the tire to be vulcanized and the mold specification, that is, the vulcanization specification information in the vulcanizer to which the tire is vulcanized, through the network. And based on the vulcanization standard matching table, it is possible to automatically determine whether or not the tire can be put into the designated vulcanizer and feed back to the operator.

The serial bar code according to the present invention can be advantageously used in the specification screening step before the inspection process or before the factory shipment, the appearance inspection step in the distribution center.

In the standard selection step, a bar code scanner may be installed on a conveyor to recognize serial bar codes, and the WM defect may be prevented from being passed to a later process by using a matching table as described above in the recognized bar codes. .

In the visual inspection step, when the appearance defect occurs and the tire suspected of defective WM is found, the barcode can be scanned and recognized using a portable barcode scanner (for example, a portable reader using a PDA) so that the operator can inquire the molding and vulcanization specifications on the screen. You can do that. Furthermore, when a WM defect occurs in the operator's screen, an alarm window may be displayed so that the operator can immediately check.
