A Poka-Yoke application in rubber industry

Abstract

Quality problems and defect products are always issues that have to be considered and eliminated in a manufacturing facility. Human effect in production is considered as one of most important root-cause items regarding defect product and quality problems. The first idea of how to minimize human factor in production has been generated by Shigeo Shingo who is an engineer of Toyota Motor Co. and this idea is named as Poka-Yoke. Poke can be translated as carelessness, absence of mind, undesirable mistake. Yoke is derived from Yokeru and can be translated as remove, elimination. This paper describes human mistakes at mixing operation in rubber industry that causes quality problems and product defect and how to eliminate these problems or defect by applying Poka-Yoke that still running at facility

Kauçuk sektörü Poka-Yoke uygulaması

Abstract

Bir üretim tesisinde her zaman gözlemlenmesi ve ortadan kaldırılması gereken konuların başında kalite problemleri ve hatalı ürünler gelmektedir. Üretimde insan faktörü ise hatalı ürün ve kalite problemlerinin en önemli kök nedenlerinden biri olarak değerlendirilmektedir. İlk olarak Toyota’da mühendis olarak çalışan Shigeo Shingo tarafından ortaya atılan Poka-Yoke fikri, insana bağlı hatanın ortadan kaldırılması anlamına gelmektedir. Poka kelime anlamı olarak; dikkatsizlik, dalgınlık, istenmeyen hata olarak dilimize tercüme edilmektedir. Yoke ise; Yokeru kelimesinden türetilmiş ortadan kaldırma, elimine etme olarak tercüme edilmektedir. Bu makalede kauçuk sektöründe yer alan malzeme karıştırma prosesinde aktif olarak uygulanan Poka-Yoke uygulaması anlatılarak, insan hatasının kaliteye etkileri ve bu hataların ortadan kaldırılmasına yönelik çalışmalar incelenmiştir.
