Description

  The present invention relates to a component information management system that manages information related to a component that is input when the component is input to a work apparatus in each process installed in a production assembly line.

  In a production / assembly line in which work devices for a plurality of production / assembly are arranged, parts used in each work device are transported from a warehouse and supplied to the work device in many cases.

  In this case, the conventional inventory management of each part is generally performed in a warehouse.

  As an example of the means, for example, an identification code (for example, a barcode) given to each component is read by a reading device (for example, a barcode reader), and this is converted into a database to manage arrival / shipment.

  In this case, with regard to the parts in the warehouse, the quantity and the like can be managed with high accuracy, but the management for transporting the parts from the warehouse to each work device on the production assembly line is not performed.

  For example, in the case of manual operation, if the delivery amount from the warehouse is wrong, this mistake is not noticed until inventory management in the next warehouse. In other words, there is a time difference between when an error occurs and when it is discovered.

  Further, when carrying out manually, there are cases where similar parts are mistaken, and it becomes difficult to specify the carry-out source of the parts that have been mistakenly used after product shipment.

  Here, Patent Document 1 discloses a production line management system for managing components and the like put into the line and operating the production line properly.

In the manufacturing line management system disclosed in Patent Document 1, a barcode that is used in a manufacturing line and includes information related to parts that are input to the manufacturing line for each unit quantity, and is to be attached to the product for each unit quantity. A barcode creation device for creating a barcode, a barcode reader for reading a barcode to be attached when the component is placed in a production line, and provided for each process in which the component is placed, and the barcode A part determination device that receives read information from the reader and determines whether or not the part is a correct part to be put into a production line based on the read information, and determines that the part determination device is not a correct part In such a case, a warning device that issues a warning is provided.
JP-A-10-254537

  However, in the conventional technique such as Patent Document 1 described above, a plurality of work processes on the production line are not managed collectively, and it can be determined whether or not the parts to be input are correct. Cannot judge whether the time is right.

  Further, since it is impossible to manage the behavior of the operator who does not notice or ignore the warning device, even if it is determined that the part is not a correct part, the part may be put into the production line.

  In view of the above facts, the present invention provides a parts information management system that can collectively manage the entire manufacturing and assembly line, and can manage not only the correctness of parts to the work equipment in each work process, but also the timing of input of the parts. Is the purpose.

  In addition to the above object, another object is to obtain a component information management system that can reliably prevent an erroneous component from being thrown in.

  The present invention relates to a parts information management system for managing information related to parts to be placed when parts are put into a work apparatus in each process installed in a production assembly line, the control system for each work apparatus. An identification code reading means for reading an identification code attached to the component, and whether the read identification code matches an identification code of a component necessary for the work device that has read the identification code. Collating means for collating, permitting means for permitting input to the working device when the identification code matches by the collating means, warning means for warning if the identification code does not match by the collating means, It is positioned above the manufacturing and assembly control system in the work equipment of each process, obtains part input history information from the control system of each work equipment, and loads each part in each work equipment. History, and has a centralized control means for managing the inventory, the.

  According to the present invention, the control system provided in the manufacturing apparatus of each process reads the identification code given to the parts to be carried in and collates with the identification codes of the parts necessary for the work apparatus in advance.

  As a result of this collation, if they match, the input to the work device is permitted. On the other hand, if there is a mismatch as a result of the collation, the warning means warns.

  In addition, a plurality of control systems provided in each work device are centrally managed by centralized management control means positioned at the higher level, and recognize the parts required for each work device from the work status of the entire production assembly line. . For this reason, for example, by incorporating the time element on the condition that the matching means matches, it is possible to perform management that takes into account the time that is different as the part but is correct as a part.

  In addition, the centralized management control means obtains part input history information from the control system of each work device and manages the input history and stock of each part in each work device. Thus, even after the product produced on the production assembly line is shipped, for example, when a part in the product is misplaced, the shipping source can be quickly grasped.

  In the above invention, the permission means is characterized in that the loading port is automatically opened physically when the component loading is permitted.

  As a result of the collation of the part identification codes, the slot for loading the product is opened only when they match. In other words, in the case of inconsistency, in addition to issuing a warning, the slot for inserting the part is not opened, so even if there is an operator action such as overlooking or ignoring the warning, the wrong part is prevented from being inserted. can do.

  In the present invention, an authentication code for identifying the operator is set for each operator who transports the component to each work device, and the verification unit is configured to verify the authentication code prior to verification of the identification code of the component. , And verification with a previously permitted authentication code is executed.

  An identification code is assigned to a part, and an authentication code is assigned to an operator who is allowed to manage the part (for example, transportation from a warehouse), and the authentication code is assigned prior to the verification of the identification code. By collating, parts management with higher accuracy can be performed.

  As described above, the present invention has an excellent effect that the entire production assembly line can be collectively managed, and the correct timing of the parts to the work apparatus in each work process can be managed, as well as the timing of loading the parts.

  In addition to the above effects, it is possible to reliably prevent erroneous parts from being thrown in.

  FIG. 1 shows a schematic diagram of a production assembly line 10 according to the present embodiment.

  The production assembly line 10 has a plurality of work processes (only three are shown in FIG. 1), and a work device 12 is installed in each work process.

  The work device 12 is provided with a manufacturing / assembly controller 14 in which a work process program is stored, and an actuator (not shown) attached to the work device 12 operates according to the sequence of the work process program.

  The manufacturing / assembly controller 14 also manages the parts 16 necessary for assembly in addition to the control of the work assembly.

  The component 16 has a structure that can be loaded into the work device 12 by opening the opening / closing lid 14B of the component loading portion 14A provided on the left side surface of the work device 12 in FIG. The opening / closing of the opening / closing lid 14 </ b> B is controlled by driving an opening / closing lid motor 17 connected to the manufacturing / assembly controller 14.

  The parts 16 are transported from the warehouse 18 by an administrator (operator) 20.

  That is, the parts 18 used for each work device 12 are stored in the warehouse 18 as an inventory, and an administrator (operator) 20 takes out the necessary parts 16 and transports them to the requested work device 12 (see FIG. 1).

  Here, parts management in the warehouse 18 is strictly managed in advance by periodic inventory inspection in the warehouse 18.

  However, the parts 16 are often taken out from the warehouse 18 by an administrator (operator) 20, that is, manually, so the quantity may be wrong from the warehouse 18 or different parts 16 may be carried out (hereinafter collectively referred to as generic names). "Human Miss"). Such human mistakes are not known at the time of occurrence, and will be detected by the above-described periodic inventory management. However, if there is a time difference between them, manufacturing and assembly with wrong quantities or different parts 16 will be executed. There was.

  Therefore, in the present embodiment, a barcode attached to the identification seal 16A attached to the component 16 is provided, and the barcode applied to the component 16 is read by the barcode reader 22 provided in each work device 12. As a result, the parts 16 are collated.

  At the same time, an administrator (operator) 20 who transports the component 16 has an ID card 20A, and the barcode attached to the ID card 20A is read by the barcode reader 22, thereby An error or the like is determined.

  The manufacturing / assembly controller 14 of each working device 12 is connected to a centralized management controller 26 via a network 24.

  The centralized management controller 26 shows the assembly progress status of the entire production assembly line 10, the increase / decrease of the parts 16 in each work device 12, the distribution of the manager (operator) 20 carrying the parts 16, information after the production / assembly, and the like. It is managed as a database.

  Table 1 shows an example, and the database items include “part name”, “part identification code”, “manager name”, “manager authentication code”, “number of parts inventory”, “use time”, “ "Use work process", "Applicable product code", and "Production assembly completion date".

  The manufacturing / assembly controller 14 provided in each working device 12 acquires necessary information from the centralized management controller 26 to determine whether or not the parts 16 can be accepted, or according to the progress of manufacturing / assembly, the centralized management controller 14 26, information related to the part 16 or information related to manufacturing / assembly is transmitted.

  FIG. 2 is a block diagram functionally showing control for parts management in the manufacturing / assembly controller 14.

  The bar code reader 22 is connected to the bar code analyzing unit 30. The bar code analyzing unit 30 analyzes the read bar code. As a result of the analysis, the bar code reader 22 determines whether the part identification code or the administrator (operator) 20 It is determined whether it is the authentication code.

  If the determined barcode is an identification code, the identification code information is sent to the identification code verification unit 32. If the determined barcode is an authentication code, the authentication code information is sent to the authentication code verification unit 34.

  A component identification code list memory 36 is connected to the identification code verification unit 32. When identification code information is input to the identification code verification unit 32, the component identification codes are read one after another from the component identification code list memory 34 and verified.

  The identification code collation unit 32 sends the collation result to the component collation result determination unit 38. This component verification result determination unit 38 determines whether or not the carried-in component 16 is compatible (acceptance accepted), and sends the result to the state management control unit 40 and the production / assembly line information acquisition unit 42. .

  The manufacturing / assembly line information acquisition unit 42 is connected to the centralized management controller 26 and determines whether or not the use time of the part 16 is appropriate when the part 16 is matched as a result of the collation and determination. For example, information such as the manufacturing and assembly status is acquired and sent to the part reception time determination unit 44.

  That is, the part 16 itself is used by the working device 12, but it is determined whether it is necessary to supply the part 16 in the present situation, thereby overdelivery or within the same working device 12. It is possible to manage the loading of different parts 16.

  More specifically, although the same part 16 is manufactured, the same lot that was manufactured until the previous day has been carried in, but from this day, it can be caused by manual carry-in, for example, when another lot is manufactured. I try to prevent mistakes.

  As a result of determination by the component acceptance time determination unit 44, the result is sent to the state management unit 40.

  On the other hand, an administrator authentication code list memory 46 is connected to the authentication code verification unit 34. When the authentication code information is input to the authentication code verification unit 34, the administrator authentication codes are sequentially read from the administrator authentication code list memory 46 and verified.

  The authentication code verification unit 34 sends the verification result to the administrator verification result determination unit 48. This administrator verification result determination unit 48 determines whether or not the imported administrator is compatible (acceptance is permitted), and sends the result to the state management control unit 40.

  The central management controller 26 is connected to the state management control unit 40. Although not shown in the figure, the status management control unit 40 receives work status information in the work device 12, in other words, concentrates all information related to the work device 12. Yes.

  All the concentrated information is sent to the central management controller 26, and the database described above is created.

  The state management control unit 40 is connected to an open / close lid motor driver 50 and an alarm driver 52.

  The opening / closing lid motor driver 50 is connected to the opening / closing lid motor 17 and controls the driving thereof to open / close the opening / closing lid 14B (see FIG. 1).

  Further, the alarm device driver 52 is connected to the alarm device 54. The alarm device 54 operates when the collation result of the component 16 does not match, or when the collation result of the manager (operator) 20 does not match.

  Hereinafter, the operation of the present embodiment will be described with reference to the flowchart of FIG.

  In step 100, it is determined whether or not the barcode has been read using the barcode reader 22. If the determination is affirmative, the process proceeds to step 102 where the read barcode is analyzed.

  The result of the analysis in step 102 is determined in step 104. If it is determined in step 104 that the component identification code is determined, the process proceeds to step 106.

  In step 106, a component identification code is read from the component identification code list, and then in step 108 collation / determination is performed.

  In the next step 110, the result of the determination is sent to the production / assembly line information acquisition unit 42, and then in step 112, the part reception time is determined. That is, the manufacturing / assembly line information acquisition unit 42 acquires information related to the operation status of the entire manufacturing / assembly line 10 from the centralized management controller 26 and determines whether or not the acceptance of the parts 16 at the present time is appropriate.

  In step 114, the determination results in steps 108 and 112 are sent to the state management control unit 40, and the process proceeds to step 122.

  On the other hand, if it is determined in step 104 that the administrator authentication code is used, the process proceeds from step 104 to step 116.

  In step 116, the administrator authentication code is read from the administrator authentication code list, and then in step 118, collation / determination is performed.

  In the next step 120, the determination result is sent to the state management control unit 40, and the process proceeds to step 122.

  In step 122, it is determined whether or not all the determination results are obtained in the state management control unit 40. That is, it is determined whether all the determination results of the collation determination of the part 16 at the step 108, the determination of the part reception timing at the step 112, and the collation determination of the administrator at the step 118 are completed, and a negative determination is made. If so, the process returns to step 100.

  Further, when an affirmative determination is made at step 122, the routine proceeds to step 124, where it is determined whether or not the loaded part 16 is appropriate.

  If it is determined in step 124 that it is appropriate, the routine proceeds to step 126, where the opening / closing lid 14B is opened (the opening / closing lid motor 17 is driven). On the other hand, if it is determined at step 124 that it is inappropriate, the routine proceeds to step 128 where an alarm is executed (the alarm device 54 is activated).

  As described above, in the present embodiment, it is determined whether or not the parts 16 carried out from the warehouse 18 and transported to the respective work devices 12 are suitable for the work devices 12, and the management for transporting the parts 16 is determined. Since it is determined whether the operator (operator) 20 is a person who has been previously permitted to carry in the work apparatus 12, it is possible to quickly determine an error in manual component supply.

  Even when the part 16 is appropriate, the receiving time in the entire production assembly line 10 may be different. For example, even if the carried-in component 16 is suitable for the work apparatus 12 that is the carry-in destination, the schedule may differ depending on the production / assembly plan. Further, although the parts 16 are the same, even when a lot is designated, the previous day may be appropriate but today may be inappropriate.

  Since it is configured to determine whether or not the entire manufacturing assembly line 10 is suitable, a highly accurate parts management system can be constructed as a parts management system.

  Furthermore, since the centralized management controller 26 receives the status information from the manufacturing / assembly controllers 14 of all the working devices 12 and creates a database, even if there is a complaint about the parts 16 after shipment, the manufacturing / assessment time, the loading source, The import manager can be recognized.

It is the schematic of the manufacturing assembly line which concerns on this Embodiment. It is a functional block diagram of the control system regarding the component management in the manufacture assembly controller installed in the working device which concerns on this Embodiment. It is a flowchart which shows a components management control routine.
