PCT No. PCT/JP80/00194 Sec. 371 Date Apr. 13, 1981 Sec. 102(e) Date Apr. 13, 1981 PCT Filed Aug. 22, 1980 PCT Pub. No. WO81/00553 PCT Pub. Date Mar. 5, 1981.A conveyor unit used for conveying objects along a predetermined conveying locus of an irregular shape at a constant speed. The conveyor unit is characterized by that it meets the following requirements: (1) Bearings are mounted on the outer periphery of a rotary disk and a rotating shaft is fitted in each of the bearings, the shaft having an arm of an article support slidably fitted therein; (2) A conveyor chain is provided which is adapted to move along a conveying locus or path of a predetermined irregular shape controlled by inner cams and outer cams and which is connected with a connecting member of the article support; (3) A rotating shaft of a sprocket to drive the conveyor chain is arranged to rotate in synchronism with a rotating shaft to drive the rotary disk. Since the conveyor unit according to the present invention meets the above-mentioned three requirements, it is possible to move objects (or articles) to be conveyed along a predetermined conveying locus of an irregular shape at a constant speed by actuating the conveyor unit. Therefore, for example, in the cases where the articles to be conveyed are containers for something to eat and drink, medical supplies, cosmetics and various kinds of materials, by disposing along the conveying locus various kinds of processing devices such as (a) content charging or filling devices, (b) container capper and sealer apparatus, (c) container's outer surface printing and labelling devices etc., it is possible to effect product processing steps continuously and in the form of an integrated work.
