Abstract

This study was conducted to develop a cylindrical paperpot manufacturing equipment which is capable of continuously producing paperpots with a constant size. The equipment consists of the soil supply part, the paper supply part, the pot manufacturing part, the paperpot cutting part and its process for manufacturing paperpot from the soil supply to the paperpot cutting is continuously performed. As a result of the performance test using this equipment, we suggest that the optimal moisture content and injection pressure to supply soil are 50%~60%, and 0.5 Mpa respectively. Moreover the appropriate temperature for adhesive strength is 150~160°C taking into account the performance of device and adhesion time. Also, considering the cutting speed and safety, it is appropriate to adopt a straight blade having a clean plan at a minimum angle of 30°. In addition, the manufacturing capacity of the developed equipment was 3300 pots per hour.

작업 편이성을 높일 수 있는 원통형 종이포트를 일정 한 크기로 생산하여 연속적 공급이 가능한 원통형 종이 포트 제조장치를 개발하고, 장치의 성능시험을 수행하였 다. 원통형 종이포트 제조장치는 상토공급부, 종이 공급 부, 종이 접착부, 종이포트 절단부로 구성되어 종이포트 제조를 위한 상토공급부터 종이포트 절단까지의 공정이 연속적으로 이루어지도록 하였다. 상토 함수율에 따른 적정 상토공급압력시험에서는 상토를 공급하는 진공압이 높을수록 종이포트의 경도와 가밀도가 높게 나타났으며, 수분 함수율이 높아질수록 경도와 가밀도는 증가하다가 낮아지는 경향을 나타내어 포트제조부로 상토를 공급하 기 위한 적정 함수율 및 공기압은 50%~60%와 0.5 Mpa인 것으로 판단된다. 제조장치의 성능과 고형접착제 에 의한 종이 접착시간을 고려하였을 때, 종이의 원통 성형이 이루어지고 가이드부와의 유착없이 연속적인 공 정이 이루어질 수 있는 적정 온도는 150°C~160°C인 것 으로 판단된다. 원통형 종이포트 절단칼날의 최적 절단 각도를 구명하기 위한 시험에서는 절단 속도와 작업의 안전성을 고려하여 최소 기울기인 30°에서 깨끗한 단면을 나타내는 일자칼날을 사용하는 것이 적합할 것으로 판단 된다. 원통형 종이포트 제조장치의 성능시험에서 종이포 트의 길이는 설정한 길이로 균일하게 제조되었으며, 종이 접착 및 상토공급 등 준비 시간을 제외한 종이포트(직경: 40mm, 길이: 40mm) 제조 작업성능은 3300개/hr로 나타 났다.
