Thornburgh, Leonla, N. J., assig'nor to American Can Company, New York, N. Y., a. corporation of New Jersey Application December 3, 1943, Serial No. 512,832 l1 Claims. (01.164-68) The present invention relates to the manufacture of containers or cans vfrom seamless or seamed tubing that has been flattened into double wall ribbon form and wound onto spools for convenience in shipment and storage and has particular reference to an apparatus for cutting the ilattened tubing into can body lengths and for distributing the resulting flattened can bodies to a plurality of machines incident to the manufacture of such bodies into cans.
An object of the invention is the provision of an apparatus for severing can bodies from fiattened double wall ribbon form of seamless or seemed tubing wherein the flattened tubing is cut into can body lengths which thereupon are advanced in timed order and are distributed to a plurality of machines such as reforming machines in which the flattened can bodies may be formed into desired can body shape, to the end that production oi can bodies will take .place at a high rate of speed.
Another object is the provision in such a machine of vacuum devices for holding cut-olf flattened or partially formed can bodies under control during their movement through the machine so that the bodies may be properly distributed to a plurality of different places of deposit and in timed order.
Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.
Referring to the drawings:
Figure l is a side elevation of a machine embodying the instant invention, with parts broken away;
Fig. 2 is a transverse section taken substantially along the broken line 2 2 in Fig. l, with parts broken away;
Figs. 3, 4i and 5 are longitudinal vertical sections taken substantially along the lines 3 3, 4 4 and 5--5 in Fig. 2;
Fig. 6 is an enlarged perspective view of a collapsed can fbody produced and distributed -by the machine; and
Fig. 7 is a transverse vertical section taken substantially along the (broken line l-l in Fig. 3.
As a preferred embodiment of the instant invention the drawings disclose a high speed machine for cutting oii` collapsed can bodies A (Fig. 6) from a continuously moving metal tube B (Fig. 3) that has been flattened into the form of a double wall ribbon. The machine is also directed to distributing these crut-od collapsed can bodies to a plurality of subsequent operation machines such as reforming machines or the like as an incident in the manufacture of tubular sheet metal can bodies. The ribbon of tubing is substantially continuous in length and is made preferably from aluminum or aluminum alloy which is well adapted to certain kinds of containers such as beer or other beverage cans.
The ribbon of tubing B may be fed from a supply of tubing which has been reeled in a, compact coil on a spool or the like (not shown) and is continuously advanced into the machine, preferably in a horizontal position. This feeding or advancing of the ribbon of tubing is brought about by a pair of horizontally disposed feed rollers ll, l2 (Fig. 3) between which the flattened tubing passes. These rollers are mounted one above the other on short drive shafts i3, lil, journaled in bearings l5, l5 (see also Figs. l and 2) formed in a pair of spaced and parallel side frames l? which constitute the main frame of the machine.
The feed rollers ll, l2 are continuously rotated in synchronism by a pair of meshing spur gears 2l, 22 (Figs. l and 4) which are mounted on the roller drive shafts i3, M. The upper gear 2l is driven Iby an idler gear 23 which is mounted on a cross shaft 2t journaled in bearings 25 formed in the side frames. Gear 23 also meshes with and is driven by a gear 2t keyed to a drive shaft 2l journaled in bearings 28 formed in the side frames. The drive shaft may be rotated in any suitable mer.
The ribbon of tubing B advanced into the machine by the feed rollers ll, l2 is received on a horizontal table 3l (Figs. 3 and 7) formed on and located between the spaced side frames ll. During its advancement across the table, the tubing is maintained in place by a recessed side guide and hold-down plate 32 which is secured to the top of the table. f
As the advancing ribbon of tubing travels across the table 3l, its leading end extends out into space beyond the inner edge of the table and comes into a cutting oi station C (Fig. 3). At this station the leading end of the tubing is in tangential relation to a rotating cut-ofi head D which cuts the tubing into can -body lengths.
The cut=-oii head D is located between the side frames il and includes a star shaped head member 35 (Figs. 2 and 3) which is mounted on and rotates. in a clockwise direction as viewed in Fig. 3. with the main drive shaft 2l. The head member is formed with a plurality of Wide flat-sided,
transverse nngers 33 which carry cutter blades 31. i
severing of the tubing B into can body lengths by the cutter blades 31 of the head D is brought about in cooperation lwith auxiliary cut-oi! blades 4I which back up the tubing during the cutting.
The turret E is rotatably mounted on a stationary turret shaft 42 (Figs. 2 and 3) keyed in place in bearings 43 formed in the side frames i1. This turret is continuously rotated in time with the cut-off head D and in a counterclockwise direction, as viewed in Fig. 3, by' a. spur gear 44 (see also Fig. 4) which is bolted to one side of the turret. The gear meshes with' and is driven by the main driving gear 23 on the drive shaft 21.
Hence as the attened tubing B advances into the cutting-off station C, between the rotating cut-off head D and the rotating carrier turret E, the blades 31 of the head and the auxiliary blades 4i of the turret cooperate in engaging opposite sides of the tubing and sever can body lengths therefrom. This action continues uninterruptedly and collapsed can bodies A are produced in rapid succession.
During this cutting off operation Just prior to the can body A being severed from the ribbon of tubing, and also just after cutting, it is h'eld under complete control by suction or vacuum cups 52 (Figs. 2 and 3). These cups are carried on the turret E, there being a cup adiacent each auxiliary cut-oi! blade 4i. in a coupling 53 wnich is threaded into the outer peripheral face of the turret. When a, vacuum cup 52 is first brought into engagement with' the free end of the ribbon A, a vacuum is established. The cup thereupon grips the tubing and holds it fest so that the severing which immediately follows is done in a precise manner.
After being cut on, the cups 52 continue to hold th'e body while the rotating turret E carries the body around to a place of deposit. In the instant machine the desired place of deposit for a particular can-body is selected from a plurality of chutes 55 (Fig. 3). These chutes lead to magazines 53 of subsequent operation machines, such as body reforming machines. The drawings show ilve of these chutes 55 arranged around th'e periphery of the turret although it will be obvious that the invention is equally well adapted for use with any number of such chutes.
In order to selectively distribute a cut-oil can body A to its proper receiving chute 35, the vacuum cups 52 are arranged in groups of a number equal to the number of chutes. In the present embodiment, as shown in the drawings, there are five cups in each group and the total number of cups around the turret is therefore a multiple of five. For convenience in explanation one group of cups and the chutes to be served by them are numbered from one to five in Fig. 3.
Hence with such a grouping of the cups, the body A held by cup number i will be deposited into chute number I, when the cup is advanced adjacent its associated chute. In like manner, the body held by cup number 2 will be deposited in ch'ute number 2, and so on until each body has been deposited in its proper chute. In this manner the can bodies are distributed equally Each cup is fastened A into the chutes 53 is brought about preferably by the timing of the making and the breaking of the vacuum in the cups l2. This timing is effected by a pair of stationary valve plates or discs 3i, 62 (Figs. 2, 3, 4 and 5) which are keyed on the stationary turret shaft 42 and which' are located one on each side of the turret and in engagement therewith. Valve disc 3| is used in connection with the numbered I, 2 and 3 suction cups, while valve disc 32 functions for suction cups numbered 4 and 5.
Valve plate 3l is formed with three concentric valve grooves 33, 33, 31 (Figs. 2 and 5) which' extend partially around the inner face of the plate in various length. These grooves communicate with ports 33, 33, 1l, which are formed in the plate and which connect with a pipe line 1I which leads to any suitable source of vacuum. The grooves are spaced radially from each other and from the center oi' the valve plate in orde;- to individually serve the I, 2 and 3 cups 52 of each group of five.
The numbered I, 2 and 3.as well as the 4 and I cups 52 communicate through their couplings 63, with' radial channels 15 cut in the turret E. The channels of the numbered I, 2 and 3 cups terminate at their inner ends in outlet ports 13 -which extend toward the left as in Fig. 2 and end at the face of the valve disc 3i. Similer outlet ports 16 for the numbered cups 4 and 3 extend toward the right (Fig. 2) and end at the face of th'e valve disc 32. This will be better understood as the description proceeds.
The channels of each cup in a group of five cups are of different lengths so that they will come into the Draper communication with diiferent valve grooves in the valve plates 6I, 32. In this way the cups numbers I, 2, 3 of each group are served respectively by the grooves Il, 33 and 61 in the valve plate 3i, while cups number 4 and 5 are served by similar concentric grooves 31, 3i (Fig. 4) cut in the face of the valve plate 62. Grooves 31, 3i communicate with ports 32, 93 whichalso lead into the vacuum pipe line 1i.
Hence in operation, when a number I vacuum cup 52 comes into position adjacent the free end of the tubing B at the cut-off station C its port 13 simultaneously comes into register with the vacuum groove 35 and thus brings the cup into communication with the source of vacuum. It is this action that causes the cup to grip and vhold the tubing. The port 13 sweeps along the arcuate length of th'e groove 35 and the vacuum in the cup holds the body after it is cut off.
When the body held by a number I cup reaches chute number I, the vacuum is broken to release the hold on the body. This is brought about by the port 13 having reached the end of the groove 65 in the valve plate 6I. Thereafter the body may be stripped off the cup and will be deposited into the chute as will be hereinafter explained.
In like manner, all the other vacuum cups 52 of each group of flve operate to establish a vacuum in the cups, successively at the cut-ofi station C. When the can body with its vacuum cup reaches its respective chute it will be released by breaking of the vacuum. Thus it will be observed that the selective vacuum operation of a vacuum cup is the result of winch groove B5, 86, 61, 31 or 9i is in communication with its radialchannels 13 and ports 13.
`Stripping. of acollapsedcan body ,A from a vacuum .cup 52l when it reaches its propergchute 55 is broughtabout by a stripper vacuum cup |0| (Figs. 2 and 3).

There vis one of the stripper members |02 located at the entrance end of each chute 55. The stripper cup |0| on each member is positioned in proper relation so that it will come into position with a held body on the turret only when that body is held by a cup corresponding to the chute into which the body is to be discharged. This relation is clearly discernible from Fig. 3 of the drawings.
The stripper cups |0| are vacuumized at the proper time by way of channels (Fig. 2) the outer ends of which come into register with curved vacuum grooves I2 formed in stationary valve discs H3 mounted on the cross shafts |03 and secured to one of each pair of the shaft bearings |01. The vacuum grooves are formed with ports ||4 which communicate with pipes ||5 (Fig. 1) leading into the vacuum pipe line 1|. 'I'here is one of these valve discs' foreach stripper member.
Hence, for example, when a' vacuum cup 52 of the number 2 series in each group brings its held can body A into position adjacent the entrance end ofthe chute number 2, the stripper cup |0| located at that chute comes .into'engagement with the body on the side opposite to that engaged by the cups 52, as best shown in Fig. 3. At this time the vacuum channel in the stripper member |02 comes into communication with the vacuum groove ||2 in the valve disc I3 and as a result a vacuum is created in the stripper cup. The cup thus gripsfthe body and .pulls it away from its holding suction cup 52.
yTo facilitatel the transfer of the body from a vacuum cup52 toa strippercup |0| a blast of compressed fair is forced into the. cup 52y to break.,v the vacuum therein and to-force the released bodyaway from the cup and into more positive engagement with-the stripper cup. This blast of compressed air is forced through the cup channels 15 inthe turret when their ports 16 come into regis- It is thought 4that the-invention and manyor itsattendant advantages wlllbe understood from the foregoing description, and it lwill be apparent that various changes may be madein the form, construction and arrangement ofthe parts without departing from the spiritiand scope of the invention or sacricing allof its material advantages.. the form hereinbefore described bein merely a preferred embodiment thereof.
