Title: Improvements in apparatus for positioning small articles
IPC: B29D99/00
Filed: 1922-01-23
Abstract: 184,138. Goodrich Co., B. F., (Assignees of Kmentt, W. D.). Aug. 4, 1921, [Convention date]. Feeding articles from hoppers and shoots.-In apparatus for positioning a number of small articles, such as washers, the articles are placed in a magazine and means are provided for separting them and feeding them through guides to the required position. The apparatus, in the form used for placing washers on pins in the vulcanizing-moulds for rubber heels, has a case 10, Fig. 2, having a spigot 13 registering with the sides of the mould, the case having a sliding part 20, preferably tubular, which forms a magazine and has slots 20<a> embracing the arms of a spider 21 on the case. The base 22 of the slide has guides 17 loosely fitting in holes therein and a plate 25. The plate 25 has passages 26 which are inwardly inclined at their lower ends and have their upper ends arranged in two annular series circumferentially but not radially aligned with two annular series of holes 29, 30 in a plate 28, Fig. 4. Between the plates 25, 28 is situated a disc 27, preferably thinner than the washers, having holes which normally register with the holes 29, 30, so that when the disc is rotated washers are moved from the holes 29, 30 to register with the holes 26 through which they fall by gravity. The plates 25, 28 are spaced to allow the washers to slide between them. The apparatus is placed on a mould and a knob 40 on a spindle 39 carrying a plate 42 is lowered thereby allowing the guides 17 to fall and to position themselves on conical surfaces around the bases of the mould pins. The knob 40 then abuts against and moves axially a sleeve 35 carrying the disc 27. Cam surfaces and rollers 36 on the spider 21 cause the sleeve 35 and disc 27 to rotate thereby transferring the washers to the guides 17 through which they fall on to the mould pins. In order not to displace the washers from the pins in removing the device from the mould, the knob is raised, thereby clamping the guides against the plate 22, and the sliding part 20 is lifted within the case 10 until the guides are clear of the washers. A webbed member 37 on the sleeve 35 agitates the washers in the magazine and a ridge 32 assists them to find the holes 29, 30.
