Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.

Abstract (eng): Purpose of this thesis was to find and study an economical way to automate the trimming of blow molded plastic products.
Blow molding technique utilizes two mold parts and after blowing plastic to final shape there is usually a seam between the two mold halves.
The seam has to be trimmed and cut to finalize the product.
This work is usually done by hand using knife.

Besides trimming the product, an automation system has also to be able to move product from the blow molding machine to a trimming workstation and from there to a pallet.
Because of the complexity of the process an industrial robot is needed to achieve both trimming and moving tasks.

As a result this thesis has recommendations how to initialize and carry out industrial automation project in plastics industry.
Abstract (fin): Tutkimuksen tavoitteena oli selvittää miten muovituotteiden valmistuksessa syntyvien jäysteiden poiston voi automatisoida ja onko se taloudellisesti kannattavaa.
Puhallusmuovaamalla valmistetun tuotteen kaksi eri muotinpuoliskoa jättävät tuotteeseen jäystesauman joka poistetaan manuaalisesti veitsellä tuotteen viimeistelemiseksi.
Tavoitteena oli myös käyttää samaa automaatiojärjestelmää tuotteen siirtämiseksi puhallusmuovauskoneesta työstöpaikalle ja siitä edelleen valmiiden tuotteiden kuljetinhihnalle.

Monimutkaisen työprosessin suorittamiseksi käytetään teollisuusrobotteja jolloin samalla laitteella voidaan suorittaa varsinainen työstön lisäksi tuotteen siirtely.
Tässä työssä perehdytään teollisuusautomaation ja robotiikan suunnitteluun ja käyttöönottoon kilpailuedun saavuttamiseksi muovituotteiden valmistuksessa.
