摘要： A toner image fixing device includes a heat roller, and a backup roller engaged with the heat roller to form a nip therebetween. A paper carrying a toner image is passed through the nip whereby the toner image is thermally fused and fixed on the paper. The heat roller, which is stained by a part of the fused toner during the fixing process, should be cleaned before a toner image is fixed on a successive paper without staining. To this end, a cleaning roller made of a felt material is pressed against the heat roller so as to be rotated together with the heat roller by a frictional force acting therebetween. The cleaning roller must be periodically replaced. The fixing device is constituted such that the replacement of the cleaning roller can be easily and quickly carried out.
摘要翻译：调色剂图像定影装置包括加热辊和与加热辊接合以在其间形成辊隙的支撑辊。携带调色剂图像的纸张通过该辊隙，由此将调色剂图像热熔并固定在纸上。在定影过程中被一部分熔融调色剂污染的加热辊，在将墨粉图像固定在连续的纸上而不弄脏之前，应该被清洁。为此，由毛毡材料制成的清洁辊被压靠在加热辊上，以便通过作用在它们之间的摩擦力与加热辊一起旋转。清洁辊必须定期更换。定影装置构成为能够容易且快速地进行清洁辊的更换。

摘要： Disclosed is a system for automatically successively inserting a plurality of U-shaped heat transfer tubes into holes of support members of an equipment such as a heat exchanger. The system has fixing means for removably fixing the support members such that the corresponding holes of the support members are axially aligned; gripping means adapted to pick up one of the heat transfer tubes and movable to bring the heat transfer tube toward the holes of supporting members; a positioning means disposed between the gripping means and the fixing means and adapted to hold the gripped heat transfer tube horizontally and to make the same align with the holes in the support members; and control means operatively connected to the gripping means and the positioning means so as to sequentially control the operation of both means in a predetermined sequence. The system operates as follows under the control of the control means. The gripping means grips the heat transfer tube and raises the same. The gripping means is then moved toward the support members while the positioning means supports the heat transfer tube. As the heat transfer tube is inserted deeper into the support members, the support of the tube by the positioning means is released. The gripping of the tube by the gripping means is released and the gripping means is then returned to the position for picking up the next tube, after the completion of the insertion of the heat transfer tube.
摘要翻译：公开了一种用于将多个U形传热管自动连续地插入诸如热交换器的设备的支撑构件的孔中的系统。该系统具有用于可拆卸地固定支撑构件的固定装置，使得支撑构件的相应的孔轴向对准; 夹持装置，适于拾取传热管中的一个并且可移动以将传热管朝向支撑构件的孔; 定位装置，设置在夹持装置和固定装置之间，并且适于水平地夹持夹持的传热管并使其与支撑构件中的孔对齐; 以及与所述夹持装置和所述定位装置可操作地连接的控制装置，以便以预定的顺序依次控制两个装置的操作。在控制装置的控制下，该系统如下操作。夹持装置夹紧传热管并提升传热管。然后将夹持装置移动到支撑构件，同时定位装置支撑传热管。当传热管更深地插入支撑构件时，通过定位装置的管的支撑被释放。在完成传热管的插入之后，通过夹持装置夹住管子被释放并且夹紧装置然后返回到用于拾起下一个管子的位置。
