Description: BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a product disassembling and assembling system and a method of disassembling and assembling the product. Discussion of the Background In the recent years, the tackling of environmental maintenance has become an urgent business for enterprises. In a specific product such as a copying machine, printer, etc., various sorts of recycling usage have been developed, from the viewpoint of resource saving and effective resource utilization. Furthermore, there exists a re-manufactured machine as one form (configuration) of the re-utilization of a used product. That is a so-called "second-hand" machine made by the minimum-necessary parts replacement and repairment by performing the outside-view cleaning and partial disassembling. Compared with the newly-made product, the guarantee of the quality is vague. Therefore, the valuation in the market is low and the cost merit is small. In such a situation, a re-manufactured machine is effectively utilized, and it is proposed that, as a device for enlarging the recycling, the quality of the re-manufactured machine is guaranteed to the same extent as that of the newly-made machine and the re-manufactured machine is put on the market. In other words, the used product withdrawn from the market is disassembled and the parts of the product thus disassembled are cleaned, reproduced, repaired, and checked. Only the parts passing the check standard are put on the production line and used in the re-manufactured machine together with newly-made parts. As the result, the quality of the re-manufactured machine is guaranteed as the same quality as a newly-manufactured machine. In addition, the valuation in the market for the re-manufactured machine is improved. Therefore, it can be expected that the product recycling is enlarged and therefore that largely contributes to energy saving. In order to produce such a re-manufactured machine, according to the technology disclosed in the published specification of Japanese Laid-open Patent Publication No. 11-239926, it has been already proposed to provide a high-quality and reasonable product recycling system for the disassembling production processes. The system includes a disassembling line for disassembling the main body of the used product and taking out the used parts from the used product, and an assembling line for assembling the new product, a first conveying device for supplying the used parts taken out on the disassembling line to the assembling line, a storage section for storing the new parts, a second conveying device for supplying the new parts from the storage section to the assembling line, and a control device for performing the control operation so as to supply the necessary amount of the new parts from the storage section to the assembling line in accordance with the assembling amount of the new product on the assembling line and the supplying amount of the used parts from the disassembling line. According to the technology disclosed in the published specification of Japanese Laid-open Patent Publication No. 11-291135, in a system of automatically assembling and disassembling a product by use of an automatic machine for automatically performing many operations, the disassembled parts can be re-used effectively. The system functions as an automatic assembling/disassembling system capable of flexibly coping with being applied to both of the assembling work and the disassembling work without changing the direction of the manufacturing line. The system further judges whether the works to be practiced is the assembling works or the disassembling works from the parts conveyed to the automatic machine. In accordance with the result of the above judgement, the system performs the automatic assembling of the parts and the automatic checking of the product, or performs the automatic disassembling of the parts and the automatic checking of the same parts. The works thus discriminated are selectively practiced in order to discriminate the parts which can be used again. However, according to the technology disclosed in the published specification of Japanese Laid-open Patent Publication No. 11-239926, it is necessary to prepare, respectively, the disassembling line for disassembling the used product and taking out the used parts at the same time and the assembling line for assembling the new product, for the respective special usage. To state concretely, the throwing-in robot, the conveying device, the disassembling robot, the checking device, and the accommodating device are necessary in the disassembling line, while the throwing-in robot, the conveying device, the disassembling robot, the checking device, and the accommodating device (groups of the same devices) are also necessary in the assembling line. Furthermore, in the technology disclosed in the published specification of Japanese Laid-open Patent Publication No. 11-291135, in general, if the procedure of assembling the product is parts a, parts b, parts c, the procedure of disassembling the product is the reversed order, namely, parts c, parts b, parts a on almost all occasions. Therefore, the work of assembling the parts a, and the work of disassembling the parts c have to be performed in the same working section, and the toolings for assembling/disassembling may become inevitably complicated. Furthermore, since the assembling line and disassembling line are judged on the lines after conveying the parts, it is necessary to always prepare the parts supplying device for assembling the parts and the parts withdrawing device after disassembling the product. The line structure may become very complicated. The lowering of the respective operation ratio cannot be avoided. On the other hand, in the future, the withdrawal and re-utilization (re-using) of the product may tend to become the responsibility of the manufacturer. When 100% of the used product is withdrawn, disassembled, and re-used, the quantity of the products may become very large (countless). According to the aforementioned background art, it is estimated that the very large specialized factory is required for disassembling the used product. Therefore, a large economic burden (load) occurs for the new facility investment. The withdrawal amount of the used product largely depends on the economic situation at present and the market tendency. When the withdrawal amount largely varies, the working situation of the aforementioned disassembling special line also largely varies. Therefore, the working may become non-effective. The economic burden and the cost increase of the re-manufactured machine cannot be avoided, in addition to the economic burden. Consequently, there is a risk that the enlargement of the recycling and the energy saving are largely damaged, or hindered. SUMMARY OF THE INVENTION Heretofore, the background arts regarding the product disassembling and assembling system and the method of disassembling and assembling the product have been described. However, according to such the background arts, there exists no advantageous functional effect for improving such a product disassembling and assembling system and method. The present invention has been made in view of the above-discussed and other problems, and to solve the above-mentioned defects and troublesome matters of the background arts. To state in more detail, in consideration of the aforementioned problems of the background arts, the present invention aims at providing an improved new product disassembling and assembling system and method. The invention aims to make the entire system compact and reduce the manufacturing cost. The invention aims at further easily realizing the cost reduction of manufacturing the product. The above aims are met by a product disassembling and assembling system according to claim 1, and a method of disassembling and assembling a product according to claim 11.

Furthermore, as shown in Fig. 8, when the detailed setting information such as the instruction for practicing the disassembling mode and the sort of the product main body N to be manufactured is received from the host computer 29 (Step S11), the necessary information such as the parts conveying path information is read out from the data base 33, and the program for controlling the respective unmanned conveying vehicles 5, 5, ......, employed in the case of conveying the parts NP and OP after being disassembled on the working line 3 into the parts storage warehouse 6 (Step S12). In accordance with the above-mentioned procedure, the works of conveying the parts OP for the product of the predetermined model can be done. By performing the processing of Fig. 7 and Fig. 8 as described heretofore, the works mentioned below can be done in the present system 1. At first, on the working line 2, in accordance with the production plan and the reproduction plan both stored in the data base 34, the units NU and OU are automatically assembled in order on the main body frame by the co-operation of the robot 20 and the conveying device 19 with the assembling mode of the apparatus main body N. The assembling is done by use of the fastening member such as screws, snap fits, etc. Furthermore, in the disassembling mode, the fastened state of the used apparatus main body O by use of the screws and the snap fits, etc. is released in the reverse order to that of the assembling mode. The used unit OU is taken out from the main body and put on the unmanned conveying vehicle 5 serving as the conveying device. The conveying device 19 conveys the main body frame in the positive (normal) direction of assembling in order the units NU and OU onto the main body frame, in the assembling mode. On the other hand, the device 19 conveys the used apparatus main body O in the reverse direction to that of the assembling mode, in the disassembling mode. Generally, the conveying device 19 uses the conveying conveyor. However, the flatcar or the unmanned conveying car (AGV) can be used instead of the conveyor. When the apparatus main body N is assembled on the working line 2 which is the main body assembling/disassembling facility, the units NU and OU of the necessary number stored in the unit storage warehouse 8 are moved onto the working line 2, as occasion demands. When the apparatus main body O is disassembled on the working line 2, the used unit OU is automatically disassembled and taken out by the co-operation of the robot 20 and the conveying device 19 and is conveyed to the cleaning facility 15, the repairing facility 17, the unit check facility 12, the working line 3, and the unit storage warehouse 8. On the working line 3 which is the unit assembling/ disassembling facility, the parts OP and NP are automatically assembled in order on the unit frame, in the assembling mode, by the co-operation of the robot 35 and the conveying device 4. The assembling is done by use of the fastening member such as screws, snap fits, etc. On the other hand, in the disassembling mode, the fastened state of the unit OU by use of the screws and the snap fits, etc. is released in the reverse order to that of the assembling mode. The used parts OP is taken out in order from the unit OU and put on the unmanned conveying vehicle 5 serving as the conveying device. In the assembling mode, the conveying device 4 conveys in order the parts OP and NP in the positive (normal) direction of assembling them onto the unit frame. On the other hand, in the disassembling mode, the conveying device 4 conveys the used unit OU in the reverse direction to that of the assembling mode. Generally, the conveying conveyor is used as the conveying device 4. However, the flatcar or the unmanned conveying car (AGV) can be used instead of the conveyor. In the assembling mode, the unmanned conveying vehicle 5 conveys the parts OP and NP of necessary number previously stored in the parts storage warehouse 6 onto the working line, as occasion demands. In the disassembling mode, the used parts OP taken out on the working line 3 are conveyed to the respective facilities of the subsequent processes; the cleaning facility 15, the repairing facility 17, the unit check facility 12, and the parts storage warehouse 6. Even though the product main body N after manufacturing is the re-produced machine assembled by use of the units OU and the parts OP, in order to guarantee the same quality as that of the newly-produced machine, after performing the reproducing treatment of the used product withdrawn from the market place; such as disassembling, cleaning, and repairing, etc., the product is finally checked. Both of the units OU and the parts OP are thrown into the conventional production line and employed in the machine to be reproduced. Mainly, regarding the check for assembling the new product main body and the check for disassembling the withdrawn used product main body O reusing the unit OU and the parts OP, in the part level, the unit level, and the main body level, almost all of the check items, devices and facilities etc can be mode common. Furthermore, as to the withdrawn and used product, the usage career per product differs from each other by other matter of course. In the aforementioned check in the disassembling mode, the data; name of the apparatus, model, manufacturing number, installment time, installment environment, usage frequency (number of the copied sheets), trouble career, parts exchanging, the actual usage results (records) accumulated during the time period when the product main body O is used; such as name of the apparatus, model, manufacturing number, installment time, installment environment, usage frequency (number of the copied sheets), trouble career, and parts exchanging career, etc. are utilized, and the checking and judgement on whether the product should be used again is performed. To state more concretely, the main body check facility 13 performs the final checking; the image checking of the product, and the electric check, etc. after assembling the main body N. In the process of performing the quality assurance of the product and the process of checking whether the product can be used again after cleaning the withdrawn used product main body O, the checking item, device, and the facility can be made common. Regarding the unit check facility 12, in the process of checking the unit property and the unit function of a respective new unit NU to be supplied for assembling the main body N and the process of checking the unit property and the unit function on whether a unit OU can be used again after disassembling and taking out of the used product main body O and performing the reproduction treatments such as the cleaning and the repairment of the taken-out used unit OU, the checking item, device, and the facility can be made common. To state more definitely in other words, the unit check facility 12 commonly utilizes the check item, the device, or the apparatus, in a process of performing the check of the unit property and the unit function of respective new units to be supplied for assembling the main body N, and in another process of performing the check of the unit property and the unit function on whether the used unit OU can be re-used after performing the reproducing treatment, such as the cleaning, repairing, etc., of the used unit OU obtained by disassembling the used product main body O and taking out the used unit OU therefrom. The parts check facility 11 causes the checking item, device, and facility to be used commonly, in the process of performing the mechanical check of the outer appearance, shape, and size, etc. of a new part NP and the other check of the electrical characteristic and the optical characteristic for the new parts NP newly processed and manufactured in order to supply them for assembling the unit NU, and in the process of disassembling the used unit OU and performing the mechanical check of the outer appearance, shape, and size, etc. on whether the parts OP can be re-used after performing the reproducing treatment such as the cleaning and repairment, etc., of the used parts taken out therefrom. The new parts NP for assembling the new product main body N are manufactured and conveyed to the parts check facility 11. The quality of the new parts is checked by the parts check facility 11. Thereafter, the checked parts are conveyed into the parts storage warehouse 6 and stored therein temporarily. On the other hand, the used product main body O, and the reproducing treatment of the taken-out used parts OP such as cleaning and repairing, etc. is performed. Thereafter, the reproduced parts check on whether the parts OP can be re-used is performed by the parts check facility 11. Thereafter, as in the case of the new parts NP, the respective sorts of parts are conveyed to the parts storage warehouse 6 and temporarily stored therein. As mentioned before, in order to assure the same quality as that of the newly-made machine even though the product is the re-manufactured machine, the used parts OP withdrawn from the market place and treated with the reproducing process are checked in the same manner as that of the new parts NP and thereby the quality can be assured. Therefore, in the parts storage warehouse 6, it is not necessary to attempt to distinguish the new parts NP from the reproduced parts OP and store them in the warehouse 6. The common storage warehouse can be used. It is desirable to use shelf, rack, flatcar, automatic warehouse, etc. The unit NU for assembling the new product main body N is assembled in order on the working line 3. The quality thereof is checked by the unit check facility 12. Thereafter, the respective sorts of unit are conveyed to the unit storage warehouse 8 and temporarily stored therein. On the other hand, the used product main body O is disassembled and the used unit OU taken out therefrom is treated with the reproducing process of cleaning and repairing, etc. Thereafter, as in the case of the new unit NU, the unit OU is conveyed to the unit storage warehouse 8 and temporarily stored therein. As mentioned before, in order to assure the same quality as that of the newly-made machine even though the product is the re-manufactured machine, the used units OU withdrawn from the market place and treated with the reproducing process are checked in the same manner as that of the new unit NU and thereby the quality can be assured. Therefore, in the unit storage warehouse 8, it is not necessary to attempt to distinguish new units NU from reproduced units OU and store them in the warehouse 6. The common storage warehouse can be used. It is desirable to use shelf, rack, flatcar, automatic warehouse, etc. According to the aforementioned system 1 of disassembling and assembling the product, between the works of producing the new product main body N and the works of disassembling the used product main body O and performing the process of offering the unit OU or the parts OP both used for producing the product, the used facilities 3 which are, in the embodiment, the working lines 2 and 3, the check facilities 11, 12, and 13, and the storage warehouses 6 and 8 are jointly used, regarding the reversible works such as the assembling of the product main body N and the disassembling of the product main body O, and the assembling of the unit NU and the disassembling of the unit OU; the checking works of the product main bodies N and O, the units NU and OU, and the parts NP and OP; and the same-sort temporary storing works of the units NU and OU and the parts NP and OP. Those jointly-used facilities mutually perform reversible operations or same-sort operations. Consequently, that results in making the installation of a plurality of similar facilities unnecessary. Furthermore, it is possible to simply realize the compact structure of the entire system and the reduction of the product manufacturing cost. Furthermore, since the host computer 29 controls, in a single step, the usage of the program and the various-sorts of data employed in those facilities, the reduction of the product manufacturing cost can be easily realized. The preferred embodiment of the present invention and the advantageous functional effects thereof over the background arts have been described heretofore. However, numerous additional modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that, within the scope of the appended claims, the present invention may be practiced otherwise than as specifically described herein.
