Title: Transferring device of composing member of tire
Inventor: SUMIUCHI MASAHARU
IPC: B60B30/04
Filed: 1988-09-06
Abstract: PURPOSE:To easily fit a composing member of a tire to a drum for post- treatment thereby to improve the working efficiency by providing a holder which is adapted to grasp said tire composing member from an outer side thereof, and a reforming mechanism mounted at the side adjacent to said post- treating drum of said holder which reforms said tire composing member approximately into a cylindrical shape by extending an end portion adjacent to said post-treating drum of said member in an axial direction. CONSTITUTION:After a moving frame is moved close to a pre-treating drum 5, an outer side of a tire composing member K is grasped by a holder 50. The member K is then transferred by the moving frame from the pre-treating drum 5 to a post-treating drum 19. At this time, although both end portions in an axial direction of the flexible member K tend to be deformed into a tapered configuration because of the shrinkage of rubber and their own weight, the end portions adjacent to the drum 19 are extended and reformed to be approximately into a cylindrical shape by a reforming mechanism 166. Therefore, an interference between the member K and the drum 19 is not given rise to at all at the fitting start of the member K. Accordingly, the member K is easily fitted into the drum 19, thereby improving the working efficiency.

Filed: 1989-08-31
Abstract: PURPOSE:To exactly judge the dirt degree of laundry and to properly automate washing by adopting the transmissibility of light in washing liquid where a detergent is completely dissolved, uniformly mixed and distributed. CONSTITUTION:With the start of washing, a change rate DELTAT for the photo- transmissibility in the washing liquid is calculated by a photodetector 12 and when it is detected the change rate DELTAT is set within the range of a set value, the photo-transmissibility at this time is compared with reference transmissibility by an arithmetic control part 16. When the photo-transmissibility is larger than the reference transmissibility, the photo-transmissibility is continuously monitored and after it is almost equal with the reference transmissibility, the light transmission after the lapse of prescribed time is adopted as data for judging the dirt degree. Reversely, when the photo-transmissibility is less than the reference transmissibility, the change rate DELTAT of the photo-transmissibility is monitored again after the lapse of prescribed time and when it is detected again that the change rate is set within the range of the set value, photo- transmissibility T is adopted. Afterwards, based on difference between the photo-transmissibility and reference transmissibility, the dirt degree is judged and a washing process is controlled.
