Description

Adopt mechanical component and the method for quality control and the abnormality detection system of IC tag

Technical field

The present invention relates to by built-in the label of use radio-frequency (RF) identification (RFID:Radio FrequencyIdentification) technology in mechanical component such as rolling bearing, joint, hub bearing (hub bearing) and clutch coupling, to mechanical component from be fabricated onto the discarded technology that manages always.

Background technology

The RFID technology is defined as the wireless data recognition technology or is loaded with the general name of the authentication media of this data identification technology, by constituting rfid system as the IC tag of data carrier, IC tag reader/writer and management with PC etc.As shown in Figure 4, IC tag is made of the IC chip and the small size antenna that are writing down merchandise news, data, and these elements are embedded in plastic cards etc., is referred to as IC tag.The IC chip deposited ID with storer with communicate by letter with control circuit etc.IC tag is installed on the object, utilizes radio communication, pick up its information, can carry out traffic administration, merchandise control authentication etc. thus by means of reader/writer.

For example, a kind of ID that opens the record of 2001-56847 communique the spy uses in the label (IC tag), even aerial coil is close to sheet metal, also can normally start, and can form very thinly, does not influence Portability.

But, the following mechanical component that IC tag is housed also do not appear, that is: can discard the mechanical component that IC tag is housed that always manage from being fabricated onto to the part of fixing IC tag.

In recent years, with regard to this situation, to the requirement of tracking power promptly to as the history of considering object, be suitable for or the tracer request of position more and more higher.For the quality management of mechanical component, hope is can be to know buying quality every manufacturing process of make finishing (material is bought, forging process, heat treatment step, grinding process etc.), batch etc. from material and making history of each mechanical component correspondingly or with batch unit ground.For instance, with the extraordinary part of these classes such as bearing, need one by one be detected, know correspondingly and make history for aircraft.For automobile and engineering machinery this class general part, owing to carry out bulk management, need carry out sampling Detection, so require to have the manufacturing history of batch unit with batch unit with bearing etc.By knowing that these make historically, when producing substandard products, the correspondence that just can change, specify scope that substandard products sneak into, improvement in the future etc. at an easy rate is also easy, and at an easy rate life of product is diagnosed and changed before mechanical fault.In addition, the judgement etc. of sneaking into to other similarity pieces also is easy to.

In the prior art, as the clear and definite this historical method for quality control of making, be that the information that every operation is produced is all remembered on invoice, all be input in the terminal of database then.

In addition, (for example the spy opens the 2002-169858 communique) once proposed to use IC tag in logistics management and stock control, even in device fabrications such as automobile, also can use IC tag, from be fabricated onto the discarded scheme that manages always.IC tag can write down and read information non-contactly.And because memory capacity is very big, so need to carry out the management of height.

Use among the method for quality control embodiment of existing IC tag in suggestion, directly record is various on the IC tag on the mechanical component relates to the information of mechanical component or write down identifying information on IC tag being installed on, by checking, just can know material and bulk management information, the various historical datas etc. of mechanical component with database.But,, thereby can not distinguish the failure cause that produces on the mechanical component because above-mentioned information only relates to mechanical component.For example, the mistake by every operation processing conditions causes can produce ropy product, and can not identify the substandard products that this processing conditions mistake is produced by testing result.Mechanical component such as rolling bearing, shaft coupling and leading screw are made of a plurality of elements, even but know testing result of the mechanical component self after the assembling etc., can not specifically find out the fault that is produced because of each element quality difference.Particularly for the mechanical component with rolling body such as above-mentioned rolling bearing, because material and low precision are little by little, the performance of mechanical component is very big with regard to difference, so use the method for quality control of existing IC tag just to be difficult to adapt among the embodiment.

In addition, in process management, for the management method of implementing invoice record and entry terminal in existing each operation, because above-mentioned record and input all need the labour, thereby most information is difficult to carry out detailed record.Especially, assemble the mechanical component such as rolling bearing of a plurality of elements for needs, each element is bought from material, via forging process, heat treatment step and grinding process, each operation is all produced in batches, the manufacturing process of each element is managed very complicated, information writes personnel and writes down with input operation and just take the time very much.Therefore, just very difficult according to the requirement of mechanical component detailed history information, and other management will relate to the cost problem.

Therefore, consider the IC tag use,, can not use the management of equipment such as automobile for above-mentioned mechanical component.Among the embodiment in above-mentioned patent documentation 1, the equipment that IC tag is installed in as management object is in the automobile, writes down the information of each operation.IC tag is installed on the frame.But for mechanical component such as rolling bearings, because element can not be as the benchmark of finishing of automobile mid frame etc., and each element all needs through forging and manufacturings such as thermal treatment in manufacture process, thus IC tag can not be installed in mechanical component originally on one's body.In addition, because the elements such as inner ring, outer ring and rolling body of mechanical component such as rolling bearing need be bought via material respectively, forging process, heat treatment step, grinding process etc. and need manage, so when utilizing IC tag to carry out quality management, there are a lot of particular problems, are difficult to effectively use IC tag.

In addition, in each plant equipment, a plurality of rolling bearings that use as mechanical component need manage bearing life, but usually are to be difficult to management.

For instance, in the fuel-burning power plant, the coal that uses that acts as a fuel is sent by the Coal Transport shipping, and is loaded on the belt conveyor by coaling machine.And then, carry to coal storage plant by belt conveyor, coal storage is piled into the mountain.When consumption, from the coal the direction which a grave faces boiler of this coal storage, carry by belt conveyor.Owing to reasons such as supply capability and burning efficiency, above-mentioned boiler can not shut down, thereby needs belt conveyor also will always be in operating condition.On belt conveyor, adopted the bearing unit that in the tubular roller, is provided with bearing arrangement, for example can adopt a nearly hundreds of bearing unit.

In such belt conveyor, if producing damage, main bearing portion such as drive division causes when unusual, because device is stopped, so need often monitor.Therefore, mounting temperature sensor or vibration transducer on bearing, whether monitor temperature or vibration change.Be directed to this,,,, consider, all monitor also unrealistic from the factor of cost so can not similarly carry out general management with the drive division bearing unit to each bearing because the roller number of supporting strap is very many in the centre of belt conveyor.Therefore, the record when being changed by the last time of bearing unit is according to specified bearing life, for security consideration is changed in advance.Carry out bearing replacing this moment, to being that suitable processing is carried out in the replacing of roller as each bearing unit, do not stop belt conveyor and also can change.

For railway locomotive, adopted the bearing of a plurality of supporting wheels in addition,, in the way of locomotive motion, can not stop easily for passenger and goods are transported to the destination.Therefore, unusual for fear of in the way of travelling, producing, when stopping, carry out regular detection and management to bearing.

In the belt conveyor of above-mentioned existing fuel-burning power plant,,, just may need to stop conveyor on bearing according to degree of impairment if the intermediate calender rolls of supporting strap produces unusually.In regular bearing replacing process, impose suitable processing, can not change though do not stop belt conveyor yet, and when non-detectable bearing abnormal conditions, can not in the state of conveyor motion, change.In addition,, also might produce not measurable unusually, thereby can not know the unusual of this unknown even carry out bearing replacing ahead of time according to the rated life time.

For the wheel support bearing of railway locomotive, when stopping, carry out above-mentioned regular detection in addition, but the express locomotive of and length distance travel long for running time, and the bearing service condition is very harsh.Therefore, only the regular detection when stopping can not be enough to the generation that prevents that bearing is unusual.And when stopping, the bearing state in the time of also can not understanding operation definitely.
