逆向自动售货机(RVM)的智能自动化

自动回收机(也称为逆向自动售货机)的许多过程可以通过智能传感系统实现自动化。这样,就可以循环利用宝贵的资源,缩短循环时间,并使流程变得可靠、经济且安全。由于采用这些技术,逆向自动售货机也是全球循环经济的核心部分。

智能回收系统:全面的自动化应用

从不同类型容器的投掷,到押金物品的分离和运输,再到压缩和收集:自动回收机流程实现自动化的可能性几乎是无限的。不仅物体的可靠检测对此起着重要的作用,而且材料的区分、防止系统的误操作或保证运输路线的高效性也起着重要的作用。该交互式图表全面概述了逆向自动售货机的所有应用。

De­tec­ti­on for Pro­fes­si­onals: The Big­gest Chal­len­ges in Re­ver­se Ven­ding Mac­hi­nes

RVM Chal­len­ge 1: Ma­te­ri­als and Textures

Whether single-​use, re­usab­le, PET, glass bott­les or cans – an auto­ma­tic re­ver­se ven­ding mac­hi­ne must be able to re­li­ably de­tect these con­ta­iners re­gard­less of shape or color. Shiny, ref­lec­ti­ve and trans­pa­rent ob­jects, some of which are he­avily de­for­med, must be re­li­ably de­tec­ted and dif­fe­ren­ti­ated.

RVM Chal­len­ge 2: High Deg­ree of Con­ta­mi­na­ti­on

Re­ver­se ven­ding mac­hi­nes are point-​of-sale sys­tems and are ope­ra­ted hund­reds of times a day by ever­yo­ne. Con­ta­mi­na­ti­on from le­aking, sp­ra­ying liquids or dust poses a major chal­len­ge for many sen­sors. wenglor’s spe­ci­ally de­ve­lo­ped tech­no­lo­gi­es can ac­ti­vely com­pen­sa­te for con­ta­mi­na­ti­on by dy­na­mi­cally ad­jus­ting the switching th­res­hold, thus en­su­ring fault-​free mac­hi­ne ope­ra­ti­on.

RVM Chal­len­ge 3: Co­lors and Sha­ding

There are no li­mits to the va­ri­ety of be­ve­ra­ge pac­ka­ging. Co­lors in par­ti­cu­lar can be a chal­len­ge when com­bi­ned with dif­fe­rent ob­ject sha­pes and the in­di­vi­du­al ligh­ting si­tu­ati­on in­si­de the re­ver­se ven­ding mac­hi­ne. wenglor sen­sors not only mas­ter the en­ti­re color spect­rum when de­tec­ting ob­jects, but also cont­rasts, grays­ca­les or sha­des.

RVM Automation: Physical Functional Principles at a Glance

RVM DNA In­si­de: Sen­sors Made for Re­ver­se Ven­ding Mac­hi­ne Sys­tems

As an auto­ma­ti­on expert for in­tel­li­gent sen­sor tech­no­logy, our wenglor de­ve­lo­pers have been de­ve­lo­ping and furt­her prog­res­sing in­ge­ni­o­us so­lu­ti­ons, for re­ver­se ven­ding mac­hi­nes in par­ti­cu­lar, for many years. Three of these pro­duct high­lights with RVM DNA are the focus here.

The PET Pro­fes­si­onal: Through-​Beam Sen­sor for PET Se­lec­ti­on OSR/OER

These through-​beam sen­sors dis­tin­gu­ish trans­pa­rent PET from other trans­pa­rent ma­te­ri­als such as glass and opaque ob­jects. It is pre­ci­sely this abi­lity that is required in re­ver­se ven­ding mac­hi­ne sys­tems. The sen­sors are equipped with two switching out­puts to show these sta­tes. Be­ca­use of the M18 th­re­aded con­nec­tor, the sen­sor is easy to ins­tall and pro­tec­ted mec­ha­ni­cally.
 
  • Dy­na­mic ad­just­ment of the switching th­res­hold for high sys­tem ava­ila­bi­lity
  • High dy­na­mic range for de­tec­ting dark ob­jects
  • Com­pact 1R ho­using de­sign (56.5 × 26 × 24 mm) with M18 th­re­aded con­nec­ti­on for high ro­bust­ness and easy ins­tal­la­ti­on
  • Re­li­ab­le dif­fe­ren­ti­ati­on between PET, glass and metal – in one sen­sor!
     

The Trans­pa­rency Expert: Retro-​Reflex Sen­sor for Trans­pa­rent Ob­jects P1RKxxx

Retro-​reflex sen­sors require a ref­lec­tor to func­ti­on and re­li­ably de­tect even trans­pa­rent ob­jects and films – ideal for de­tec­ting ob­jects in re­ver­se ven­ding mac­hi­nes. The M18 th­re­ad fas­te­ner pro­vi­des mec­ha­ni­cal pro­tec­ti­on and enab­les easy ins­tal­la­ti­on. 
 
  • Dy­na­mic ad­just­ment of the switching th­res­hold for high sys­tem ava­ila­bi­lity
  • Com­pact 1R ho­using de­sign (56.5 × 26 × 24 mm) with M18 th­re­aded con­nec­ti­on for high ro­bust­ness and easy ins­tal­la­ti­on
  • De­tec­ti­on of clear ob­jects with single-​lens op­tics

The All-​Rounder: Ult­ra­so­nic Dis­tan­ce Sen­sor U1RT004

These ult­ra­so­nic sen­sors eva­lu­ate the sound ref­lec­ted from the ob­ject. They de­tect al­most any ob­ject re­gard­less of the ma­te­ri­al and its con­di­ti­on. Thanks to the in­no­va­ti­ve trans­du­cer, this sen­sor has a par­ti­cu­larly wide sonic cone at close range. This allows a very wide range of pi­eces to be re­li­ably de­tec­ted on con­ve­yor belts in re­ver­se ven­ding mac­hi­nes.
 
  • No con­ta­mi­na­ti­on thanks to ult­ra­so­nic waves
  • Com­pact 1R ho­using de­sign (56.5 × 26 × 24 mm) with M18 th­re­aded con­nec­ti­on for high ro­bust­ness and easy ins­tal­la­ti­on
  • Wide sonic cone for de­tec­ting all ob­jects
  • Re­mo­te ma­in­te­nan­ce and con­di­ti­on mo­ni­to­ring thanks to IO-​Link 1.1
