Description

Technical Field

[0001] The present invention relates to the technical field of tire production, and more specifically, to a method for preventing manual input errors when changing specifications of an all-steel cord fabric cutting machine. Background Art

[0002] As is well known, during the manufacturing process of all-steel tires, after the tire blank is composed of different skeleton materials and rubber components, it becomes a finished tire through the vulcanization process. Due to different technological design requirements, usage purposes, and functions of the skeleton materials that make up the tire blank, there are numerous specifications for the skeleton materials such as the belt layer and the reinforcement layer. Moreover, parameters such as the cord specifications, cutting angles, cutting widths, the specifications of the rubber sheets used, the rubber sheet laminating methods, and the edge wrapping methods for various specifications of the belt layer and the reinforcement layer are also different. At present, when changing the specifications of the skeleton materials during the production process, operators need to manually input parameters such as the cutting angle, cutting width, the specifications of the rubber sheets used, the rubber sheet laminating methods, and the edge wrapping methods into the formula in the human-machine interface of the cutting machine. When manually inputting the formula parameters, operators need to input the formula parameters item by item, which takes a long time and affects the production efficiency of the cutting machine. Frequent input errors occur during manual input. Once the parameters are input incorrectly, the cutting of the skeleton materials will be incorrect. After the skeleton materials are cut incorrectly, the tire design requirements cannot be met, and the skeleton materials can only be scrapped or downgraded, resulting in waste of manufacturing costs and increasing the manufacturing costs of the enterprise. And re-producing the skeleton materials affects the smooth completion of the production plan and ultimately affects the production efficiency. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a method for preventing input errors when changing specifications of an all-steel cord fabric cutting machine, in which operators cannot manually modify the formula parameters, avoiding the risk of manual input parameter errors and saving the time for changing the formula.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a method for preventing input errors when changing specifications of an all-steel cord fabric cutting machine, which is characterized by including the following steps:

[0005] Step 1. Establish an MES skeleton material formula database, and each skeleton material formula in the database is displayed by a code;

[0006] Step 2-1. Establish a local skeleton material formula database in the operation computer of the all-steel cord fabric cutting machine. Each local skeleton material formula in the database is the same as the information contained in the MES skeleton material formula database, and information such as the braking coefficient of the rubber sheet, the coiling braking coefficient, and the coiling meters is added. Only management technicians or authorized personnel have the authority to modify or delete the formula parameters;

[0007] Step 2-2. The local formula of the skeleton material is displayed in code, and there are two display methods. One is the list of code formulas for all skeleton materials, and the local code formula list is hidden in the background, and the operator cannot see or change it. The other is to only display the list of code formulas for the current production plan being executed;

[0008] Step 3. Establish a MES production plan formula database. The production plan is displayed in the form of a code list. The MES production plan formula information is consistent with the MES skeleton material formula information, and information such as production shift, production order number, production machine, and production quantity is added;

[0009] Step 4. Before changing the specifications, according to the production plan arrangement, search for the formula code retrieval information to be replaced in the MES production plan formula database, and select the formula code to be replaced and upload it to the current production plan code formula list of the all-steel cord fabric cutting machine operation computer;

[0010] Step 5. The operator uploads the currently executed production plan displayed in the all-steel cord fabric cutting machine human-machine interface menu to the corresponding output station. The human-machine interface locks the formula parameter values and only displays the formula parameter values. The operator cannot modify the formula parameters. At the same time, the MES production plan formula is compared with the local formula parameters of the skeleton material. If the two formulas and parameters are consistent, go to Step 6-1;

[0011] Step 6-1. After the formula information parameters in the human-machine interface are verified to be consistent, they are transmitted to the all-steel cord fabric cutting machine PLC and enter the setting of Step 7-1;

[0012] Step 6-2. If the MES production plan formula in the human-machine interface is inconsistent with the local formula data information of the skeleton material, it is necessary to return to Step 2-1 and operate again;

[0013] Step 7-1. Enter the setting interface in the human-machine interface to set parameters such as the angle and width of the cutting knife and splicer of the all-steel cutting machine. After the setting is completed, adjust the unwinding and splicer parts to be consistent with the set formula data parameters, and start the cutting machine to perform automatic operations such as material cutting and joint splicing, and enter Step 8;

[0014] Step 7-2. After the setting is completed, if the cutting machine cannot be started for automatic cutting, joint splicing and other operations, it is necessary to return to Step 7-1 and set again;

[0015] Step 8. After the skeleton material produced by automatic cutting, splicing and film lamination is output, the all-steel cord fabric cutting machine operation computer feeds back the output material information to the MES system. The MES confirms that the output specification is consistent with the planned formula specification, and prints a quality traceability transfer card for the use of the subsequent process.

[0016] In Step 1, the parameters in the MES carcass material formula include information such as the cord specification, cutting angle, cutting width, film specification, film laminating method and size used for the carcass material.

[0017] In Step 5, when the formula verification between the MES production plan formula and the local carcass material formula is inconsistent, the cutting machine will give a warning prompt and cannot proceed to the next operation.

[0018] In Step 7-2, after the human-machine interface is set up, if the requirements of the formula data parameters are not met, the cutting machine cannot automatically cut and splice joints.

[0019] The beneficial effects of the present invention are as follows: The local formula parameters of the all-steel cord cutting machine are locked, avoiding the risk of manual input errors caused by operators changing the formula parameters. The local formula list and the production plan execution list are displayed separately, avoiding errors or misclicks when selecting a formula in the formula list and preventing incorrect size changes. When the operator changes the formula, there is no need to manually input the parameters item by item, saving the time for changing the formula. Detailed implementation mode

[0020] This example includes the following steps:

[0021] Step 1. Establish a MES carcass material formula database. Each carcass material formula in the database is displayed by a code. The parameters in the MES carcass material formula include information such as the cord specification, cutting angle, cutting width, film specification, film laminating method and size used for the carcass material.

[0022] Step 2-1. Establish a local carcass material formula database on the operation computer of the all-steel cord fabric cutting machine. The local carcass material formulas in the database are the same as the information contained in the MES carcass material formula database, and information such as the film braking coefficient, coiling braking coefficient, and coiling length is added. Only management technicians or authorized personnel have the permission to modify or delete the formula parameters. Other personnel can only call the formula before obtaining authorization.

[0023] Step 2-2. The local carcass material formula is displayed by a code and has two display methods. One is the list of all carcass material code formulas, and the local code formula list is hidden in the background and cannot be seen or changed by the operator; the other is to only display the list of production plan code formulas currently being executed (the operation interface only displays the list of plan formulas that need to be executed currently).

[0024] Step 3. Establish a MES production plan formula database. Adjust the production plan information daily according to the production plan. The production plan is displayed in the form of a code list. The MES production plan formula information is the same as the MES carcass material formula information, and information such as production shift, plan order number, production machine, and production quantity is added.

[0025] Step 4. Before changing the specifications, according to the production plan arrangement, search for the recipe code retrieval information to be changed in the MES production plan recipe database, select the recipe code to be changed, click Confirm, and upload the recipe list of the production plan code currently executed by the operation computer of the all-steel cord fabric cutting machine.

[0026] Step 5. The operator double-clicks or drags the currently executed production plan displayed in the recipe list of the currently executed production plan code in the human-machine interface menu of the all-steel cord fabric cutting machine to the corresponding output station. The human-machine interface locks the recipe parameter values and only displays the recipe parameter values. The operator cannot modify the recipe parameters. At the same time, the MES production plan recipe is compared with the local recipe of the skeletal material and the local recipe parameters of the cutting machine. If the two recipes and parameters are consistent, proceed to Step 6-1.

[0027] In Step 5 above, when the MES production plan recipe is not consistent with the local recipe verification of the skeletal material local recipe, the cutting machine will issue a warning prompt and cannot proceed to the next operation.

[0028] Step 6-1. After the recipe information parameters on the human-machine interface are verified to be consistent, they are transmitted to the PLC of the all-steel cord fabric cutting machine, and proceed to Step 7-1 for setting.

[0029] Step 6-2. If all the recipe information parameters on the human-machine interface are displayed as "0", it means that the MES production plan recipe is inconsistent with the data information of the skeletal material local recipe, and it is necessary to return to Step 2-1 to operate again.

[0030] Step 7-1. Enter the setting interface on the human-machine interface, and set parameters such as the angle and width of the cutting knife and the splicing machine of the all-steel cutting machine by pressing P8. After the setting is completed, adjust the unwinding, splicing machine and other parts to be consistent with the set recipe data parameters, and start the cutting machine to perform automatic operations such as material cutting and joint splicing, and proceed to Step 8.

[0031] Step 7-2. After the setting is completed, if the cutting machine cannot be started for automatic cutting, joint splicing and other operations, it is necessary to return to Step 7-1 to set again.

[0032] In Step 7-2 above, after the setting on the human-machine interface is completed and the requirements of the recipe data parameters are not met, the cutting machine cannot automatically cut and splice joints.

[0033] Step 8. After the skeletal material produced by automatic cutting, splicing and film laminating is output, the operation computer of the all-steel cord fabric cutting machine feeds back the output material information to the MES system. After the MES confirms that the output specifications are consistent with the planned recipe specifications, it prints a quality traceability transfer card for the use of subsequent processes.
