积水化学成立于1947年,当初以制造和销售塑料相关产品的业务为主。1950年积水化学在日本首次开发出透明胶带;两年后,开始正式生产硬质氯乙烯管,为排水、供电、供气等基础设施建设做出了巨大贡献。1955年,积水化学在聚氯乙烯管接口的挤压成形技术上获得成功;进入70年代,又在日本首次开发出组合式住宅。

1. Summary
综述
Sekisui Heim residential houses (herein “Heim”) are made of factory-produced modules called “Units” which can be combined to complete any house plan. All “Units” to compose a house are unique and have different parts in different combinations. It is an important process to select and pick up about 30,000 parts correctly for each house, out of about 300,000 listed parts and feed them to the production line in time of work. In this paper, the writer will introduce to you how to pick up the parts constituting Heim units, and certain technical points of the “HAPPS” (Heim Automated Part Pick-up System) which has materialized such method. In the end, the writer will touch on the efficiency and accuracy of such part pick-up method.
Sekisui Heim住宅(以下简称Heim)是由工厂生产的称为单元的模块组成,可以组合来完成任何住宅计划。所有组成房子的单元都是独一无二的,并且有不同的组合。从30万件已列明的零件中,正确挑选出3万件左右的零件并及时送到生产线上是一个重要的工序。在本文中,作者将向您介绍如何拾取构成Heim单元的部件,以及实现该方法的HAPPS (Heim自动拾取部件系统)的某些技术要点。最后,对这种零件拾取方法的效率和准确性进行了探讨。
