Specific embodiment

Hereinafter, being illustrated based on management system of the embodiment shown in figure to conveyer belt of the invention.

The management system 1 (hereinafter referred to as management system 1) of illustrated conveyer belt of the invention is in fig. 6 and 7 in Fig. 1 It falls into a trap during the use of the conveyer belt 12 of the illustrated belt conveyer device 9 for being secured to use site and calculates its remaining longevity Order Ja.In addition, the management system 1 calculates its predetermined age Jf before using conveyer belt 12.

In the belt conveyer device 9, conveyer belt 12 be set up between driving pulley 10a and driven pulley 10b and with Defined tension tensioning setting.Between driving pulley 10a and driven pulley 10b, conveyer belt 12 is by with interval appropriate configuration It is supported in backing roll 10c with long dimension direction.

Conveyer belt 12 is constituted by core layer 14 and across the upper covering rubber 13a and lower covering rubber 13b of core layer 14, The core layer 14 is made of the core 15 formed using steel cord or canvas.Core layer 14 is subject to for being tensioned setting transmission Component with 12 tension.In addition to this also additional width direction end rubber 13c, enhancement layer etc. are appropriate, necessary for conveyer belt 12 Component and constitute.

In the transmission equipment side of conveyer belt 12, lower covering rubber 13b is supported by backing roll 10c, in reversion side, upper covering rubber 13a is supported by backing roll 10c.In the transmission equipment side of conveyer belt 12, three backing roll 10c are arranged in parallel in bandwidth direction, are led to These backing rolls 10c is crossed, conveyer belt 12 is supported to concavity with the defined angle of the v-groove.

Be stored in storage unit 4: band Specifications Database 4a pre-enters the specification of conveyer belt 12；Allowed band number According to library 4b, the allowed band about each cuit (P1~P7) is pre-entered by the specification of each conveyer belt 12；It uses Condition database 4c；And correlativity database 4d.

In this embodiment, further, inventory database 4e is stored in storage unit 4.In inventory database 4e, input There is the replacement conveyer belt 12a of the use site of conveyer belt 12 or the conveyer belt 12 in the stock ground (stock yard) on its periphery Quantity in stock (inventory's length).It should be noted that also currently used conveyer belt 12 and replacement are set with conveyer belt 12a sometimes For same size, but it is also set as different size sometimes.For example, also making currently used conveyer belt 12 and replacement conveyer belt sometimes The material of the upper covering rubber 13a of 12a is different.

It shows as exemplified in fig. 2, it is defeated by the specification (specification A, B, C ...) of each conveyer belt in Specifications Database 4a Enter to have material, the size etc. of member of formation.For example, input has: above covering the rubber kind of rubber 13a and lower covering rubber 13b Class (rubber physical property) and thickness, the material (physical property) of core 15 and outer diameter, constitute core layer 14 core 15 quantity, arranged side by side The mutual width direction gap of core 15, bonding length of both ends interconnecting piece 16B etc..

If Fig. 3 is exemplified, in allowed band database 4b by each conveyer belt 12 specification (specification A, B, C, the allowed band about each cuit (P1~P7) ...) is inputted.Due to seven cuits in this embodiment (P1~P7) is input to server 2, and therefore, input has the allowed band of seven cuits, if but being input to server 2 Cuit is only the abrasion loss P1 of upper covering rubber 13a, then only the allowed band of abrasion loss P1 is input to allowed band number According to library 4b, if the cuit for being input to server 2 is three, only the allowed band of three cuits is entered To allowed band database 4b.

If the abrasion loss P1 of upper covering rubber 13a becomes excessive over time, it is easy to produce failure.Cause This, such as abrasion loss P1 is set with, the allowed band of defined upper limit value has been determined.

If impact force P2 becomes excessive, it is easy to produce failure.Regulation has been determined thus, for example being set with to impact force P2 Upper limit value allowed band.

If tension P3 becomes excessive, it is easy to produce failure, if becoming too small, is easy to produce tortuous and generates failure. The allowed band of defined upper limit value and lower limit value has been determined thus, for example being set with to tension P3.

No matter become over time as the mutual width direction gap of core 15 of the typical example of index P4 It is excessive still to become too small, all it is easy to produce failure.Thus, for example as defined in being set with and having determined to width direction gap P4 The allowed band of upper limit value and lower limit value.

If the bonding length of the both ends interconnecting piece 16B of the typical example as index P5 increases over time, It is easy to produce the removing of engagement.The allowed band of defined upper limit value has been determined thus, for example being set with to bonding length P5.

If the conveying speed P6 of the typical example as index P6₁Become excessive, then the abrasion loss P1 of upper covering rubber 13a increases Greatly, if becoming too small, the Weight Loaded of the conveying object C of per unit area increases and the load becomes large to conveyer belt 12.Therefore, Such as to conveying speed P6₁It is set with the allowed band of upper limit value and lower limit value as defined in having determined.If as index P6's The conveying weight P6 per unit time of another typical example₂Become excessive, then the load becomes large to conveyer belt 12.Thus, for example To the conveying weight P6 per unit time₂It is set with the allowed band of upper limit value as defined in having determined.

No matter as index P7 typical example use environment temperature P7₁, humidity P7₂It is excessive or too small, all it is easy to produce The failure of conveyer belt 12.Thus, for example to temperature P7₁, humidity P7₂It is set with upper limit value and lower limit value as defined in having determined Allowed band.If the hardness P7 of the conveying object C of another typical example as index P7₃It is excessive, then it is easy in upper covering rubber 13a Generate damage.Thus, for example to hardness P7₃It is set with the allowed band of upper limit value as defined in having determined.If as index P7 Another typical example conveying object C shape P7₄There is acute angle portion in outer surface, then be easy to generate in upper covering rubber 13a Damage.Thus, for example to the shape P7 of conveying object C₄It is set with and has been determined that the surface in the conveying object C being put into has acute angle The allowed band of the defined upper limit value of the ratio of the quantity of partial conveying object C.

If Fig. 4 is exemplified, input has the belt conveyer device 9 of the use site in use condition database 4c In use condition.The use condition is for example are as follows: conveying speed, the conveying weight per unit time of conveying object C；Belt wheel 10a, The outer diameter etc. of 10b, backing roll 10c.In addition, use environment temperature, the humidity of conveyer belt 12；(material is (hard for the specification of conveying object C Degree, oil content), shape, temperature etc.) also become use condition.

That is, the use condition and above-mentioned cuit P6, P7 repeat.Accordingly it is also possible to use device state input unit 5f And the data of use condition are input to server 2 by use environment input unit 5g.Kind of the use condition whenever conveying object C It is re-updated when the use conditions variation such as class variation.

In correlativity database 4d, input has the use condition and biography indicated about previously used many conveyer belts Send the data of the correlativity of the specification of band and the actual service life Jr of conveyer belt.That is, using item by what parsing was accumulated before this Part (above-mentioned cuit P6, P7), each data with specification, the actual service life Jr of conveyer belt 12 can be grasped in advance and be used Condition and correlativity with specification Yu actual service life Jr.

For example, with conveying speed P6₁It becomes faster and actual service life Jr shortens, with conveying weight P6 per unit time₂ Become larger and the service life Jr on border such quantitative correlativity that shortens is input to correlativity database 4d.In addition, with making With environment temperature P7₁, humidity P7₂Get higher and actual service life Jr shorten, with conveying object C hardness P7₃Become larger and the actual longevity Life Jr shortens, for the shape P7 of conveying object C₄For with outer surface have acute angle portion conveying object C ratio become larger and Actual service life Jr such quantitative correlativity that shortens is input to correlativity database 4d.

If Fig. 5 is exemplified, by specification (specification A, B, C, the ...) input of each conveyer belt in inventory database 4e Measure (inventory's length) in stock.Inventory database 4e is updated when replacement is with the storage of conveyer belt 12a and outbound.Cause This, becomes the state that input has nearest quantity in stock.

Operational part 3 becomes data based on the cuit (P1~P7) input by each input unit 5, is input to advising The specification of the conveyer belt 12 of lattice database 4a and each cuit (P1~P7) for being input to allowed band database 4b Allowed band calculates the composition of the remaining service life Ja of conveyer belt 12.

If describing in detail, then compare over time each cuit for being input to server 2 data and Corresponding allowed band.Here, compared with other cuits, the variation of abrasion loss P1 to the disturbance degree of remaining service life Ja most Greatly.Thus, for example, calculating change conditions (rate of change) of the data relative to allowed band of abrasion loss P1.Based on calculating Change conditions, calculate inputted abrasion loss P1 data reach allowed band it is outer until the required time, by the meter The time of calculating is as remaining service life Ja.

Compared with other cuits, influence of the variation of the bonding length P5 of both ends interconnecting piece 16B to remaining service life Ja Degree is also bigger, and therefore, change conditions (rate of change) of the data based on bonding length P5 relative to allowed band calculate institute The required time until the data of the bonding length P5 of input reach outside allowed band, using the calculated time as interim Remaining service life Jb₂.Then, until the data of above-mentioned abrasion loss P1 can also being reached outside allowed band the required time as Interim remaining service life Jb1, by each interim remaining service life Jb1, Jb₂In the shortest remaining service life as remaining service life Ja.

About other cuits (P2~P4, P6, P7), for example, if being input to the data of server 2 in allowed band It is interior, then calculate remaining service life Ja with not considering these data.On the other hand, if these data consider outside allowed band These data simultaneously calculate remaining service life Ja as following exemplifiedly.

Think: situation of the data of these cuits (P2~P4, P6, P7) outside allowed band within the allowable range The case where compare, it is big to the load of conveyer belt 12.Therefore, for these each cuits, setting keeps remaining service life Ja shorter The calculated COEFFICIENT K in ground (0 < K < 1).The size of the COEFFICIENT K be not it is the same, based on the real data accumulated before this, root It is weighted according to the different degree of each cuit, is made it different preferably according to cuit.

Then, firstly, not considering the data of cuit (P2~P4, P6, P7), it is computed as described above out the interim remaining longevity Order Jb.Then, in the case where these data are outside allowed band, by the COEFFICIENT K that each cuit is set (K1, K2, K3...) remaining service life Ja (Ja=Jb × K1 × K2...) is calculated multiplied by calculated interim remaining service life Jb.

In the present invention, based on calculated remaining service life Ja, the actual service life Jr of conveyer belt 12 is determined.That is, due to Conveyer belt 12 using sart point in time and calculate remaining service life Ja time point be it is known, therefore, clearly go out from making During sart point in time to the time point for calculating remaining service life Ja.It adds and calculates during can clearly go out to this Remaining service life Ja resulting period be determined as actual service life Jr.Actual service life Jr in the present invention refers in principle to be based on The service life that calculated remaining service life Ja is determined like this.

Operational part 3 calculates remaining service life Ja with defined period (for example, two weeks or one month).Preferably In, notify the Email in calculated remaining service life Ja to be sent to subscriber terminal's equipment 7 from server 2.

In the management system 1, further, pass through operational part 3 before conveyer belt 12 is secured to belt conveyer device 9 To calculate the predetermined age Jf of conveyer belt 12.As noted previously, as correlativity database 4d is input to storage unit 4, because This, becomes the data for the use condition (above-mentioned cuit P6, P7) that can use the conveyer belt 12 and the specification of the conveyer belt Data and correlativity database 4d, the composition of predetermined age Jf is calculated before using conveyer belt 12.

Here, use condition, each data with specification, actual service life Jr of the conveyer belt 12 used before tight are defeated Enter, store and updates in correlativity database 4e.As calculate the conveyer belt 12 predetermined age Jf when, after update Correlativity database 4e composition.

Therefore, each replacement used from now on the predetermined age Jf of conveyer belt 12a is used whenever replacement conveyer belt 12 The correlativity database 4e being updated when (12a) is being filled based on the replacement use condition of conveyer belt 12a and with specification It is calculated by operational part 3 before being connected to belt conveyer device 9.By updating correlativity database 4e, meeting like this Reflect the severity of nearest use condition.Therefore, the precision of prediction of the predetermined age Jf of conveyer belt 12 (12a) is mentioned It is high.Calculated predetermined age Jf is sent to subscriber terminal's equipment 7 from server 2.

Calculated predetermined age Jf has some errors.Therefore, it by being computed as described above out remaining service life Ja, is easy Determine the more appropriate replacement period of conveyer belt 12.

That is, in the present invention, other than above-mentioned remaining service life Ja, the predetermined longevity is also calculated before using conveyer belt 12 Order Jf.Since predetermined age Jf and remaining the two service life in service life Ja can be grasped, the service life of a side is not depended solely on, It is easily mastered the more appropriate replacement period of conveyer belt 12.Moreover, because predetermined age can be grasped before using conveyer belt 12 Jf, therefore, it is easy to ensure that for preparing the temporal of conveyer belt 12a of replacement, the surplus in fund.Therefore, it reduces and passes It send the extra inventory of band 12 (12a) or is become easy during shortening inventory, for reducing the operating cost of conveyer belt 12 It is advantageous.

It can evaluate are as follows: in the case where the difference of the actual service life Jr of the conveyer belt 12 and predetermined age Jf is small, in advance The precision of prediction for determining service life Jf is high, and in the case where the difference is big, the precision of prediction of predetermined age Jf is low.Accordingly it is also possible to When calculating the predetermined age Jf of the replacement that uses after the conveyer belt 12 with conveyer belt 12a, the reality based on the conveyer belt 12 Service life Jr compared with the predetermined age Jf of the conveyer belt 12, to correct the predetermined age Jf of replacement conveyer belt 12a.

For example, setting makes the correction coefficient T of actual service life Jr and predetermined age Jf diminution difference.Then, by meter The replacement of calculating corrects predetermined age Jf multiplied by correction coefficient T with the predetermined age Jf of conveyer belt 12a.Correction coefficient T setting Are as follows: make the size of the difference of actual service life Jr and predetermined age Jf for example reduce 30%~80% or 40%~80% or The value of person 50% or so.Correction coefficient T can also be set as making the size of the difference of actual service life Jr and predetermined age Jf The value for reducing 100% carries out making the consistent correction of the two.

Management system 1 of the invention can also be using the update and above-mentioned predetermined longevity for carrying out above-mentioned correlativity database 4d The composition of this two side of the correction of Jf is ordered, but the composition for only carrying out either one can also be used.

As the embodiment in this way, as the basis for calculating remaining service life Ja, if in addition to the abrasion loss of upper covering rubber 13a Except P1, also using at least one cuit in other cuits P2~P7, then for the use according to conveyer belt 12 The actual conditions at scene for suitable remaining service life Ja are advantageously to calculate.

In this embodiment, further, quantity in stock and transmission based on the conveyer belt 12 for being input to inventory database 4e With 12 calculated remaining service life Ja, the order of replacement conveyer belt 12a is sent from server 2 to subscriber terminal's equipment 7 The contact ordered is urged in the contact in period.

If describing in detail, then when operational part 3 calculates remaining service life Ja, confirm at the time point be input to inventory The quantity in stock of the conveyer belt 12 of database 4e.Then, in the length of the replacement conveyer belt 12a of needs than the quantity in stock that confirms In the case where length, low stock.In this case, specified time limit needed for considering delivery for calculated remaining service life Ja come Replacement is specified with the order period of conveyer belt 12a, the Email in order period is notified to be sent to subscriber's end from server 2 End equipment 7.The order period adjacent to when, urge the Email for ordering replacement conveyer belt 12a to be sent to and orders from server 2 Consumer's terminal device 7.Therefore, can adequately be prepared for the replacement of conveyer belt 12.

If issuing the contact for ordering replacement conveyer belt 12a from subscriber terminal's equipment 7, the contact is via server 2 It is sent to producer's terminal device 8, or is sent directly to producer's terminal device 8.Based on the order, producer is by order The conveyer belt 12a of specification and length delivers goods to the stock ground of subscriber.

It should be noted that if all length of conveyer belt 12, then can also replace whole (overall length), but longer in perimeter sometimes In the case where only replace necessary part (necessary length).Thus, for example the number that will be inputted about cuit (P1, P4, P5) Server 2 is input to according to together with the data of circumferential position that can determine conveyer belt 12 for the data.Needs can be grasped as a result, The position of the conveyer belt 12 of replacement and length.

Can also be stored in the storage unit 4 of server 2 input have replacement conveyer belt 12 required for expense database, Input has the database etc. for replacing the required time.In the case where using such composition, conveyer belt can will be replaced Cost information required for 12 is sent to subscriber terminal's equipment 7 from server 2.It is carried out in addition it is possible to use server 2 is unified Replace timetable management required for conveyer belt 12.

Permission in the case where being added the abrasion loss P1 of lower covering rubber 13b to cuit, to abrasion loss P1 Range (upper limit value) is pre-entered to allowed band database 4b.Then, it can also be constituted using following: be input to service In the case that the abrasion loss P1 of the lower covering rubber 13b of device 2 is outside allowed band, to subscriber terminal's equipment 7 or producer At least one party in terminal device 8, which sends, notifies Email of the abrasion loss P1 outside allowed band.Receive the mail Can subscriber, producer be coped with as follows: to rotation status (rotate), the In of the backing roll 10c of belt conveyer device 9 Whether there is or not skidding, scraper plate occurs to have contactless etc. checked with lower covering rubber 13b between conveyer belt 12 and belt wheel 10a, 10b. The unfavorable condition of belt conveyer device 9 can be eliminated in advance as a result,.
