ATTO R N EYS DRIVING OR IDLER DRUM FOR ARTICLE FEEDING BELT CROSS REFERENCE TO RELATED APPLICATION This application is related to an application in the name of Elton G. Kaminski, Ser. No. 838,847, filed July 3, 1969, and is a continuation-in-part of applica tion, Ser. No. 85,087, filed Oct. 29, I970, now abandoned.
BRIEF SUMMARY OF THE INVENTION This invention relates to a drum for use with an article feeding belt in an apparatus where a succession of like articles are fed along a path to a succession of operating stations where operations are performed on the articles. A machine of the type to which this invention relates is shown in US. Pat. to Kaminski et al., No. 3,231,065, issued Jan. 25, 1966.
In the apparatus of that patent, a stainless steel belt was provided and said belt had sprocket holes along its edges and was driven by a sprocket drum. The belt had apertures in which the articles were seated in order to be fed by the belt. The articles particularly disclosed were beverage can ends. An arrangement was provided for adjusting the position of the belt so that the articles carried thereby were properly oriented at the several operating stations.
In the Kaminski application, Ser. No. 838,847, mentioned above, the belt is disclosed as being of fabric impregnated with Neoprene or similar material and the belt had non-stretchable elements such as steel wires or cables embedded therein to give it non-stretch characteristics. The belt was internally toothed and was driven by a toothed drum. A more sophisticated apparatus for adjusting the position of the belt with respect to the operating station was disclosed.
According to the present invention, the belt may again be of fabric impregnated with Neoprene or the like and having non-stretchable elements embedded therein as in said copending application. The belt is designed (in the embodiment shown) to feed circular articles such as beverage can ends to operating stations for the attachment of pull tabs and scoring and the like. According to the present invention, the belt has no teeth and no sprocket holes and the article feeding apertures are relied upon for moving the belt in cooperation with plugs secured to the feeding drum, which plugs are arranged to fit snugly into the article feeding apertures.
Since from time to time articles of different sizes will have to be processed, it will be necessary to change belts, and to provide a plurality of belts, having apertures for each size of article to be processed. This, of course, necessitates changing drums, or the plugs or the drums which engage the article feeding apertures. According to the present invention, a plurality of sets of plugs, adapted to cooperate with belts having apertures of different sizes, may be provided; and it is a simple matter to remove one set of plugs and replace it with another.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING FIG. I is a perspective view of a drum and a fragment of a belt in operative relation thereto.
FIG. 2 is an axial elevational view of the drum and belt.
FIG. 3 is an enlarged cross sectional view of a portion of the drum at which the belt is tangentially disposed with respect to a driving plug.
FIG. 4 is a fragmentary elevational view of a drum, with parts in cross section, showing the mounting of the plugs on the drum; and
FIG. '5 is a fragmentary plan view of the same.
DETAILED DESCRIPTION The article carrying belt is indicated at It) and is provided with a series of equally spacedcircular apertures 11 in which the articles, for example can ends, are seated to be carried along to the operating stations. The drums are indicated at 12 and are mounted upon shafts l3. Adjusting means may be provided as at M. It will be understood that the adjusting means may be as outlined in the above patent or in the above mentioned application. The adjusting means do not form a part of the present invention.
According to the present invention, at least the driving drum. is provided on its periphery with a plurality of driving plugs 15. In the drawings, there are shown eight such driving plugs, such that as the belt passes around the drum 12, each article feeding aperture II of the belt is engaged by one of the driving plugs 15. It will be understood, however, that it is not necessary for each and every aperture II to be engaged by a plug and that four plugs 15 could be used instead of eight. It is only necessary that at least one plug be in full contact with an aperture at all times. That is, before the belt moves to a position where the aperture 11 in the belt disengages from a plug 15, another aperture must be fully seated on another plug 15.
The plugs 15 may simply be circular discs warped to fit on the surface of the drum. It will be understood that as the circular apertures II are bent in passing around the drum, the circular configuration becomes elliptical. The same would of course be true of the circular plug 15. Preferably, however, the plugs 15 will be turned, milled and contoured to the required configuration. It must be noted also that the leading and trailing edges of the plugs 15, as indicated at 15a and 15b, must be configured such that they engage and disengage the apertures 11 .without interference. In other words, they must be profiled much as gear teeth. As a matter of assistance in aligning the belt with the drum, the plugs are preferably domed as at 16 and they may have a shank 17 which is pressed into a hole 18 in the drum. The thickness of the plugs 15 should be at least the thickness of the belt to insure proper gripping.
It is of course important that the drum which intermittently drives the belt be provided with the plugs as above described but it is also desirable that the idler drum or drums over which the belt passes employs the same plug constrution. The use of plugs on the idler drum assures that there will be no slippage between the belt and idler drum to avoid abrasion of the drum and wear on the belt.
While in the embodiment described above, and shown in the drawings, the work pieces are circular, and therefore the apertures in the belt are circular, and the plugs are shaped to fit the said apertures in their distorted condition as they pass around the drum, it should be understood that the invention is adaptable to other shapes of work pieces. It is only necessary that the apertures in the belt have a configuration to seat the articles snugly. and that the plugs be shaped to fit the belt apertures as they are distorted in passing around the drum, and are configured at their leading and trailing edges to engage and disengage the apertures in the belt without interference.
It is important that the plugs be easily removed, and replaced with other plugs of different sizes, so that articles of other sizes may be accepted in different sized apertures in other belts. As best seen in FIGS. 4 and 5, the plugs are seated in flats which are milled into the periphery of the drum. One such circular flat is indicated at 19 in these Figures. The flats will be ofa diameter to accept the largest plug, and smaller plugs may then be seated in the same flats. In the particular example shown, it will be noted that the plug 15 is smaller than the flat 19, so that a larger or smaller plug could be seated in the flat. The shank 17 is preferably threaded, and the plug is held in place by means of a washer 20 and nut 21. Because of the particular configuration of the plug described above, the plug must be properly oriented on the flat, and maintained in its properly oriented position. For this purpose the plug and the drum are provided with drilled holes, and a pin 22 is seated therein. Each set of plugs will be provided with shanks of identical diameter, and with holes for the orienting pins. Thus the changing of sets of plugs is a simple and speedy matter.
The endless belts must of course have a joint, and this is usually a welded joint. Flexing of the joint tends to ultimately break the joint. it is therefore important to minimize flexing by making the drums of relatively large diameter. Thus the drum should have at least one inch of diameter for each 0.001 inch thickness of the belt, i.e. where the belt is 0.015 inch in thickness, the drum should be at least 15 inches in diameter. The amount of flexing of the belt with these parameters will not adversely affect the joint.
It will be clear that numerous modifications may be made without departing from the spirit of this invention and therefore no limitations not specifically set forth in the claims should be implied and no such limitation is intended.
