Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin component production instruction device in a resin component coating process for coating a resin component such as a resin bumper mounted on a vehicle body.

[0002]

2. Description of the Related Art In an automobile factory, a resin part, for example, a resin bumper (hereinafter, also simply referred to as a bumper) is generally coated with three basic steps including a cleaning step, an undercoating step and a topcoating step as shown in FIG. Has become. First, in the molding process, the production of resin bumpers is started based on the vehicle production plan. The produced molded resin bumper is sent to a coating process, put into a cleaning process and washed, and then a bumper suitable for the jig that has been conveyed is loaded, and the bumper is coated through an undercoating process and an overcoating process. Then, the coating bumpers that pass the inspection result are unloaded, sent to the vehicle assembly process, and assembled to the vehicle body assembled in the vehicle body assembly process.

At that time, the resin bumper is introduced into the cleaning process in the conventional manner such as the vehicle production plan, the stock status of the bumper before cleaning (stock P), the stock status of the bumper after cleaning (stock Q), and the bumper coating jig. It was done by the judgment of the operator who put in the cleaning process by seeing the return situation of.

As shown in FIG. 9, a bumper coating jig 60.
The jigs 60 (hereinafter, simply referred to as jigs) are attached to the bumper coating carriage 62 (hereinafter simply referred to as carriages) for each type (specification) of the bumpers 64, and the jigs 60 are removable from the carriages 62. In this way, the jig 60 attached to the trolley 62 normally circulates in each step in the cleaning step and the undercoating step and the overcoating step (hereinafter, when both steps are collectively referred to as a coating application step). Is configured. When the bumper 64 is loaded on the jig 60, the bumper 64 suitable for the type of the jig 60 is attached.

The cleaning process is mainly carried out to completely remove the solvent adhering to the molding resin bumper, and the undercoating process is mainly carried out for the purpose of adjusting the surface for improving the finish appearance of the topcoat. The top coating process is the final process of painting,
The purpose is to add aesthetics and environmental durability.

[0006]

However, in such a conventional system, the bumper is thrown into the washing process based on the experience and intuition of the worker who put the washing process, and the fluorocarbon bumper is used to wash the resin bumper. In that case, the problem of inventory of cleaned bumpers did not appear so much because the time of the cleaning process was relatively short, but nowadays the cleaning of resin bumpers is switched to water-based cleaning due to the complete abolition of CFCs, and the time of the cleaning process In addition to the fact that the vehicle production plan and the order of the jigs to be transported do not match in the first place as a matter of fact, the following paint application may not be possible with the operator's experience and intuition as described above. The fluctuation of the supply from the cleaning process to the bumper required in the process became large, and it was necessary to have a large inventory Q after cleaning. On the other hand, however, the switch to water-based cleaning made the cleaning process physically longer, and the stock area after cleaning decreased by that amount, so the amount of bumper stock after cleaning can be kept to the minimum necessary. It has been demanded.

Further, the increase in the stock after cleaning is also due to the jig replacement method. That is, conventionally, according to the vehicle production plan, the jig ratio (composition ratio of various jigs) is set based on the specifications of the vehicle to be produced immediately (for a work unit in a factory, for example, 1/2 day), Although the jigs were replaced, the actual vehicle production plan and the order of the bodies that are actually assembled and flown in the body assembly process are different, so the specifications of the bumper you want to produce are transferred. It did not match the jig.

The present invention has been made in view of the above problems of the prior art, and it is a production instruction of a resin part capable of effectively reducing the inventory after the cleaning step in the resin part coating step such as a bumper. The purpose is to provide a device.

It is based on the process diagram shown in.

Similarly, it has a paint application process input sequence output unit 28 that outputs the paint application process input sequence information determined by the comparison means 22. Of course, the above is a functional division, and in terms of hardware, each file 1
2, 14, 16 and 18 may or may not be the same internal storage device, and the calculating means 20 and the comparing means 2
2 and each of the output units 24, 26, 28 may or may not be the same arithmetic unit.

Further, the main body 10 is provided via an input / output interface 30 as an external device at a production management computer 32 provided in a vehicle body assembly process and at an entrance of a paint application process (for example, an entrance of an undercoat process). The jig information detecting means 34, the jig information detecting means 36 provided at the exit of the coating material application process (for example, the downstream of the bumper unloading station 52), and the jig ratio information as jig ratio information outputting means. Indicator 38 for providing to jig replacement workers

And a display 42 for providing the paint application process input sequence information to the paint application process input operator as means for outputting the paint application process input sequence information.

The vehicle body production sequence information stored in the vehicle body production sequence information file 12 is the production sequence of the vehicle bodies actually assembled in the vehicle body assembly process as described above, and in this embodiment, information acquisition is easy. From this point of view, the vehicle body production order information is acquired based on the vehicle body introduction information from the production management computer 32 in the vehicle body assembly process. More specifically, the production management computer 32 keeps track of the vehicle body information that has been input and passed through the engine compartment process, which is the top process of body production, in the order of passage, and the main body 10 uses the production management computer 32 to identify such vehicle body information. Receives the throw-in information, extracts items related to bumper specifications (vehicle model, bumper specifications, etc.) from the information on one vehicle (see Fig. 3), and converts them into data only for the order of vehicle specifications related to bumpers. (See Figure 5). This data is used as the vehicle body production sequence information, and the vehicle body production sequence information file 12
Stored in. Therefore, the vehicle body production order information corresponds to the actually required bumper order (and jig order).

The input jig order information stored in the input jig order information file 14 and the empty jig arrival order information file 16
The empty jig arrival order information stored in the table is the order of the jigs put into the paint applying step in the shift and the order of the empty jigs returning to the entrance of the paint applying step. Then, in order to enable actual information detection, the insertion jig order information and the empty jig arrival order information are respectively acquired from the jig model data detected by the jig information detection means 34 and 36. ing.

More specifically, the jig information detecting means 34,
Reference numeral 36 is composed of a known identification information system. That is, the type data of the resin bumper (or the type data of the jig) that is suitable as identification information for each jig that goes through the paint applying step (undercoating step, topcoating step)
An identification information plate (not shown) is attached as identification information holding means on which the identification information is written. On the other hand, as shown in FIG. 2, the identification information plate is provided at the inlet of the undercoating process located downstream of the bumper loading station 50. An information reading station 34 is installed, and another identification information reading station 36 is installed at the exit of the paint application process, for example, downstream of the bumper unloading station 52. Therefore,
The jig loaded with the bumper at the bumper loading station 50 to be applied to the paint coating step (undercoating step) is read in the content (model data) of the identification information plate when passing through the identification information reading station 34, and is sequentially loaded. It is stored in the jig order information file 14. Similarly, when the bumper is unloaded at the bumper unloading station 52 and the jig becomes empty, the contents (model data) of the identification information plate are read when passing through the other identification information reading station 36, and the jigs are sequentially emptied. It is stored in the jig arrival order information file 16.
By using the well-known identification information system as described above, the information on the passed jig can be efficiently, promptly and accurately acquired. In addition, as shown in FIG.
Since bumpers with poor coating quality that have failed inspection after the overcoating process may be forwarded for re-overcoating, the order of the jigs thrown in the paint applying process (information on the order of the entering jigs) and the paint applying It does not necessarily match the order of empty jigs that return to the entrance of the process (empty jig arrival order information).

The washing process throwing order information stored in the washing process throwing order information file 18 is the order of bumpers thrown into the washing process at the shift, and in this embodiment, the contents determined by the comparison means 22 are the same. It is stored as it is.

Based on the vehicle body production sequence information stored in the vehicle body production sequence information file 12, the calculation means 20 makes the next shift production plan for each jig group that goes around the cleaning process and the paint coating process. It calculates the jig ratio to achieve. The specific calculation method is as follows. First, the range of bumpers to be produced in the next shift is set from the vehicle body production order information (see FIG. 5), and the ratio Gi (%) of each bumper (specification i) in that range is obtained. Then, according to the following formula, specifications of various bumpers i
Calculate the number Ni of jigs corresponding to. Number of jigs Ni = maximum number of jigs in process M × (bumper ratio Gi / 100) Thus, by determining the jig ratio based on the production sequence of the actually assembled vehicle bodies in the vehicle body assembly process ,
The ratio is more accurate than the one in which the jig ratio is determined based on the production plan as in the past, and it is possible to suppress the increase in inventory due to the undelivered amount due to the shortage of jigs.

In this embodiment, comparison means 22 is provided for determining the optimized bumper loading order for the cleaning process and the paint coating process on the premise of the jig ratio calculated as described above. . The comparison means 22 has a function of determining the order of the resin bumpers to be put into the cleaning process and the paint applying process, and the determination of the order of putting into the cleaning process is stored in the vehicle body production sequence information file 12. Based on the vehicle body production order information and the loading jig order information stored in the loading jig order information file 14, the determination of the loading order for the paint application process is performed by the empty jig arrival order information file 16 It is performed based on the empty jig arrival order information stored in the above and the cleaning process loading order information stored in the cleaning process loading order information file 18. How to determine the order of input,
In each case, the two pieces of information are matched (matching process) to perform matching. Details of this processing will be described later with a specific example.

The jig ratio information output section 24 is the calculation means 20.
The jig ratio information calculated in step 3 is converted into a predetermined format for output to the display 38. Also,
The cleaning process input sequence output unit 26 converts the cleaning process input sequence information determined by the comparison unit 22 into a predetermined format for outputting to the display 40. Further, the paint application process input sequence output unit 28 performs a process of converting the paint application process input sequence information similarly determined by the comparison means 22 into a predetermined format for outputting to the display 42.

Further, the indicator 38 for providing the jig ratio information to the jig exchange operator is composed of, for example, a CRT display. Further, the display 40 for providing the cleaning process input sequence information to the cleaning process input operator and the display 42 for providing the paint application process input sequence information to the paint application process input operator are, for example,
It is composed of an electronic bulletin board using LEDs.

Next, the operation of the resin component production instruction device configured as described above will be described with reference to the flowchart of FIG. At that time, FIGS. 5 to 7 will be referred to as appropriate.

When the power is turned on and the program is started, first, the main body 10 receives the input vehicle body information from the production management computer 32 via the input / output interface 30, and selects from the vehicle body information (see FIG. 3) of one vehicle. Items related to bumper specifications (vehicle model, bumper specifications, etc.) are extracted and converted into data only for the order of vehicle body specifications related to the bumper, and the data is stored in the file 12 as vehicle body production sequence information (S1). ). As a specific example, it is assumed that the obtained vehicle body production order information is as shown in FIG. 5, for example.

Then, the calculation means 20 uses the vehicle body production sequence information registered in the vehicle body production sequence information file 12 to produce the next shift production plan for each jig group that goes through the cleaning process and the paint coating process. The jig ratio for achieving the above is calculated in advance (S2). For example, if the vehicle body production order information file 12 stores the vehicle body production order information as shown in FIG. 5 as described above, the calculation means 20 should first produce the vehicle body production order information in the next shift. A bumper range is set, and ratios Gi of various bumpers (for example, specifications i = A, B, C, D) within the range are set.
After each (%) is calculated, the number Ni of jigs corresponding to the specification i of each bumper is calculated using the above-mentioned formula.

The calculation result of step S2 is converted into a predetermined output format by the jig ratio information output unit 24, and then sent to the display (CRT) 38 through the input / output interface 30 so that the jig replacement worker Is displayed on the screen (S3). The jig replacement worker compares the jig ratio displayed on the display (CRT) 38 with the current jig ratio, and performs the replacement work only for the changed jig.

When the jig replacement is completed and the production is carried out on duty, the jig information detecting means (identification information reading station) 34 determines the type i (= A) of the bumper loading jig passing through the entrance of the undercoating step. , B, C, D) are sequentially detected by reading the contents of the identification information plate attached to the jig, and these are stored in the file 14 as the input jig sequence information (S4).

Then, the comparison means 22 causes the vehicle body production sequence information registered in the vehicle body production sequence information file 12 in step S1 and the insertion jig sequence information file 1 detected in step S4.
The optimum order in which the bumper should be loaded into the cleaning process is determined by collating it with the loading jig order information stored in 4 (S).
5). Specifically, based on the loading jig order information, whether there is a bumper of the same type within the predetermined search range from the beginning of the vehicle body production order information that should be produced on duty in order from the beginning of the loading jig order information. If it exists, it is judged that the cleaning process input is good, and a cleaning process input instruction is issued. The search range is preset to an appropriate value (for example, the amount for one hour). For example, assuming that one shift is ½ day (8 hours) and 800 shifts are produced, the search range for one hour is 80. If there is no specification of the same type within the search range (80 units) from the beginning of the remaining part of the vehicle body production order information for the specification of a certain order in the loading jig order information, an alarm is output and immediately. Continue the above matching process for the specifications in the next order. Regarding the specifications of the order in which the alarms are output, the corresponding bumpers do not exist and the jigs will be left over.Therefore, depending on the operator's judgment, replace the jigs or consider the next shift. Leave it alone. A specific example of the process of step S5 and the result thereof is as shown in FIG.

As described above, in this embodiment, the insertion jig order information, that is, the order of the jigs that pass through the inlet of the undercoating process (the inlet of the paint coating process) and the vehicle body actually assembled in the vehicle body assembly process. The reason for this is that the optimum order of injection into the cleaning process is determined by matching the production order. In other words, in order to reduce the inventory Q after cleaning, it is most effective to match the bumper that has completed the cleaning process with the jig that returns to the entrance of the paint application process (undercoating process). In this respect, the cleaning process time and the paint coating process (undercoating process and overcoating process) time are almost the same, and the quality inspection after the overcoating process is rejected and it is forwarded for re-overcoating. Except in some cases, it can be considered that the jigs that go around the paint application process will return to the entrance of the paint application process (undercoat process) in the order in which they are put into the paint application process (undercoat process). If the bumpers are put into the cleaning process in the order of the jigs that have passed through the (undercoating process) inlet, the bumper that has completed the cleaning process and the jig that returns to the inlet of the paint coating process (undercoating process) are almost the same. This is expected.

The result of the determination in step S5 (the order of the bumper cleaning process loading) is stored in the cleaning process loading sequence information file 18, converted into a predetermined output format by the cleaning process loading sequence output unit 26, and then input. It is sent to the display device (electric bulletin board) 40 through the output interface 30 and displayed to the operator who puts in the cleaning process (S6). The worker who inputs the cleaning process
The bumper is loaded into the cleaning process according to the cleaning process loading sequence information displayed on the display (electric bulletin board) 40.

Then, the jig information detecting means (identification information reading station) 36 is connected to the bumper unloading station 5.
Read the contents of the identification information plate attached to the jig for the type i (= A, B, C, D) of the empty jig that returns to the entrance of the paint application process after the bumper is unloaded in 2 Are sequentially detected by and are stored in the file 16 as empty jig arrival order information (S7).

Then, the comparison means 22 causes the cleaning process input sequence information determined in step S5 and stored in the cleaning process input sequence information file 18 and the empty process stored in the empty jig arrival sequence information file 16 detected in step S7. A matching process is performed with the jig arrival order information to match the two, and the optimum order in which the bumper should be put into the paint coating process is determined (S8). The content of the matching process is the same as that described in step S5. As described above, the order of being applied to the paint coating process (undercoating process) and the order of actually returning do not always match because they may be forwarded, so in this step, the actual coating process (undercoating process) ) Match the order of the jigs returned to the entrance with the cleaning process loading order (which always comes out from the cleaning process in this order) so that the bumpers that can be loaded will load more and more. A concrete example of the process of step S5 and the result thereof is shown in FIG.
As shown in.

The determination result of step S8 (the coating order of the bumper coating process) is converted into a predetermined output format by the coating process coating order output unit 28, and then the input / output interface 3 is used.
It is sent to the display device (electric bulletin board) 42 via 0 and displayed to the paint application process input worker (S9). At the bumper loading station 50, the paint application process loading operator
According to the paint application process input sequence information displayed on the display (electric bulletin board) 42, the cleaned bumper is loaded on the jig and applied to the paint application process.

Therefore, according to the present embodiment, the jig ratio is obtained based on the actual vehicle body production information (vehicle body production order information 12). Therefore, the jig ratio is based on the production plan as in the conventional case. Since the ratio is higher than that of the above, it is possible to suppress the increase of the inventory due to the undelivered amount due to the shortage of jigs. Therefore, it is possible to reduce the production fluctuation of the finished product according to the specifications.

Further, according to the present embodiment, on the premise of the above jig ratio setting method, first, the order of the jigs passing through the entrance of the paint coating step (undercoating step) (put-in jig order information 14). And the production sequence (vehicle body production sequence information 12) of the vehicles actually assembled in the vehicle body assembly process, the bumper cleaning process loading sequence (cleaning process loading sequence information 1).
Since 8) is determined, it is expected that the bumper that has finished the cleaning process and the jig that returns to the entrance of the paint coating process (undercoating process) will match. Then, the order of the jigs that actually returns to the entrance of the paint coating process (undercoating process) (empty jig arrival sequence information 16) and the cleaning process loading sequence information 18 are compared, and the matching specification sequence is obtained. Since the order of injection into the paint application process (undercoating process) was set, the bumper that completed the cleaning process and the jig that returned to the entrance of the paint application process (undercoating process) almost completely matched. Therefore, the inventory Q after cleaning can be effectively reduced.

Further, according to the present embodiment, since the detection of the passage order of the jig is performed by the identification information system,
Accurate data can be acquired quickly and efficiently.

The accuracy of the jig ratio is improved, and the order of the resin parts to be put into the washing step is determined based on the vehicle body production order information and the throwing jig order information sent to the paint applying step. The finished resin parts and the jig that returns to the entrance of the paint application process are matched, and the arrival order information of the empty jig that actually returns to the entrance of the paint application process and the cleaning process input order information. Since the order of the resin parts to be put into the paint application process is determined based on the above, it is possible to further match the resin parts that have completed the cleaning process with the jig that has returned to the entrance of the paint application process. , Inventory of resin parts after cleaning process It can be reduced.
