I BEARING HEAD FOB CAN-CLOSING MACHINES.
The invention relates to new and useful improvements'in seaming heads for can closing machines, and more particularly to a seaming head provided with a chuck and a 5 body portion rotatable relative thereto,
which body portion carries the seaming rolls for rolling'a can end and flange on a can body into a double seam."
An object of the invention is to provide a further object of the invention is pro-' vide a device of the above type, wherein the.
surface speed imparted to the seaming rolls varies with the change in diameter of the double seam as the parts are rolled into the,
seam, thus preventing in rolls on the metal.
I fihese and other ,objectswill in part be obvious and will in part be hereinafter more fully disposed. Infthe drawin gs Figure 1 is a sectional view through a seaming head embodying my improvement, the section being taken through the second operation rolls;
Fig. is an enlarged detail showing a portion of the can," the chuck and the seaming roll'at the beginning of the second operation, and
Fig. 3is a similar view of the parts at the completion of the second operation. The invention is directed to a seaming head havi a rotating 0l1U=zk and seaming Q rolls whic have mterengaging parts. Either the chuck is rotated to rotate a can which is to be closed, or the chuck is stafi, tionary, andthe body portion of the head rotated to cause the seaming rolls to t'avel about the can. The seaming rolls arepreferably carried by levers which are cam-actw ated for bringing the rolls into contact with a sliding of the seamthe ca'n end and for rolling the can end,
together with the flange on the can body, into a double seam. .The seaming head has a pair of opposed first operation seaming evers carry seaming rolls, and also a pair of secon operation levers carrying seaming rolls.
The invention is particularly directedto means associated with the chuck'and rotating therewith, if the chuck rotates or held so stationary therewith, if the chuck stands .hold the chuck from y Application flled Iune,27,1927. Ser1a1' 11'o. 201,842.
still, which means engages the seaming rolls for imparting rotation thereto. This means is ayielding means, and is so arranged that the point of contact with the seaming rolls for imparting rotation thereto is always at the samedistance from the axis of the head, as the contact oint between the seaming roll and metal and moves inwardly toward the axis as the parts of the metal are rolled into the double seam, so that the speed imparted to the seaming olls will vary with the change in diameter of the double seam and thus prevent slippage of the seaming rolls on the metal. The purpose of the invention is to provide means of the above type for driving the seaming rolls through the impingement of the seaming rolls on the rotating means,'so that the rolls are not rotated merely by their contact with the metal. This provision of means for rotating the seaming rolls insures that the roll is constantlyin movement so as to roll up on to the metal during the turning of the part into a double seam. Where the rolls are rotated solely through the contact with the metal, there are times when the seaming r'oll comes to a stop and slides. This results in what is usually referred to as dead heads having imperfect seams. By the use ofmy yielding means for rotating the seaming rolls, all liability of slippage is avoided.
Referring more in detail to the drawings, the seaming head includes a body portion 1 on which is mounted a chuck 2. This chuck is rotatable in a hearing. A spindle 3 is attached to the chuck forrotating the same, Instead of rotating the chuck, the body portion of the head may rotate about the chuck, in which case, the spindle will be used to rotation. It is essen- 95 tial that either the body portion of the head rotate, carrying the seaming rolls mounted thereon around the can, or that the chuck rotate, in which case,the head is held stationary, and the can is rotated within the seaming rolls. The seaming rolls, according to the present embodiment of the invention, are mounted on 1eve rs.' These levers. are arranged in pairs, and each lever carries a seaming roll. In Fig. 1', there are shown two 5 levers 4, 4 which carry seaming rolls 5, 5. These are the second operation seaming rolls. The first operation seaming rolls and levers for supporting'the same are similar in construction to those shown in Fig. 1, except as no v method ofoperating the same, is similar to to the shaping of the seaming roove in the.
seaming rolls. The structureo the seaming head shown in part in the drawings, and the that described in thepatent granted I. F. Warme, June 24, 1919, No. 1,307,888, and illustration and description of the first operation seaming rolls and themeans for oper-' ating the head "and the spindle is notthought necessary. Each of the second operationlevers is pivoted at 8, and these levers are swung on their pivots by a oam'9 whichis mounted on the seamin head so that it may move longitudinally o the chuckspindle.
's cam engages members 10 when it is of the can end, which end is to be attached to the canbody. The chuck is rovided with anannular'groove'12, and 'wit a projecting annular portion 13 at the upper side of thisgroove 12. Each seaming roll is provided with anlannular groove 14 forming spaced projecting members. 15 and 16. The seammg roll is also provided with a seaming groove 17. The annular groove .14 receives the projecting portion 13 of thechuck. This interengagementof the chuck and the seaming rolls is of the usual character. The seam- 1n 'rolls'are held on the seaming levers bi suitable bolts 18. Associated'with the chuc I plate 'is changed between the chuck 2 and the shoul-' 2 is a steel plate 19. "This steel der 0 onthe spindle 3. The plate is thus y attached to the spindle, so as torotate 16 is cut away with-thespindle, if it is arotating spindle, andto standstationary with the s indle,
if it is .a stationa spindle type 0 head. The upper 'jwall o the annular. projection slightly so. asto provide a shoulder '21."
of the chuck that the'outer edge portion of ltheprojectioni'lfion the 'seammg rolls 'will wedge between the yieldingbplate 19 and said I projecting portion 13; and
spring plate. grippingic'ontact of the s ring platoon the seaming rolls will cause t e seaming rolls to rotate when the head travels about the'spindle, or if the head is stationar and 'the spindle and spring plate rotate. t is understood of course,.that during the formation of the double seam, the
the seamin rollstoengage a so as to avoid a 4 I v the seaming rolls-and the metal parts. In other words, the seaming rolls are constant steel plate'19is so posi-- fltioned relatlv'eto the annular projection 13 1 likewise e gripped by. the
seaming rolls move inwardly toward the axis of the head. The first. seaming operation rolls engage-a flange on a can end and, radually cause it to turnunderneath the ange on thecan body, and the parts rolled to the a ositionshown in Fig. 2 of the drawings. his is the position of the metal parts at the completion'of the first operation in the .double seaming, and at the beginning of the second operation in the double seaming. During the completing ofthe second.operation, the second operation seamingroll also moves inwardly to the position shown inFig. .3, as. themetal parts are more closely r'olledinto adouble seam and'the over-all-diameter .of the seamdecreases. During the inward movement ofzthe first operation rolls, the
the flexible late 19 w the axis 0 the head. The first operation rolls then 'are'moved outof contactwith the ppin't'i of a tata; with 1 spring plate 19. and the second operation move inward: toward rollscomin'g into action, will make contact I with the spring plate, fand the line of co'ntact therewith will gradually: move 'i'n,' t0- ward the axis of the head as the metal parts decrease in diameter due to vthe "completing of the double: seam. As the eter of the double seam decreases, the'point of contact between these seamin rolls and the spring plate 19 shifts inwar ly sfo that the surface speed imparted to'fthe. seaming roll by the spring plate 19 :will varyto accord with the change in outer double seam, 'Thus it isthat 'the seaming rolls are-driven at proper speed,' even though the diameter of the metal where contact. 00-.
external diam diameter of the curs between the'rolls and the metal varies,
possible; slippage between ly'rotating and travelingup on the metal as it is forced inwardly to complete the d011-' lble seam. -,'The slippage which occurs in ordinary seaming heads, occurs more. fre be tween the second operation 'ro metal parts, and I have, therefore, mustrated the second operation rolls'and the the) method of driving said second operation rolls 5 through connection with this yielding plate associated with the chuck; It is understood,
of coursei that the first; operation -rolls a1- tion rolls o'rm-the second operation r'o ls; a
