Definitions

  • This invention relates to conveyor systems for moving can end parts, namely shells, through end conversion apparatus wherein the shells are scored, sometimes embossed, and have an operating tab secured in position with respect to a separable pouring panel.
  • 5,158,410 shows a typical metal (usually stainless steel) type of belt.
  • Such continuous belts do operate at higher speeds, but they generally utilize a vacuum system to hold the ends in place m openings in the belts as these parts travel through the tooling; this usually produces an additional load on the belt drive, and tends to collect dirt which poses another impediment.
  • problems involving poor belt life difficulties in forming a splice when such belts are replaced, or threading a continuous belt about drive and take-up drums and througn tne tooling as part of the belt replacement process.
  • Patents Nos. 4,799,846 and 4,946,208 disclose efforts to avoid such turning of the snelis an /or ends. Namely Patent 4,799,846 discloses end shell carriers fitted to a continuous belt, and Patent 4,946,028 discloses roughened rims surrounding the snell-receivmg opening, m a continuous belt. Thus, it has been recognized tnat turned ends between work stations have been a long time cause of spoiled ends. A system which will positively retain the ends against rotation, without vacuum, is highly desirable.
  • U.S. Patent No. 3,196,817 discloses a multi-carrier conveyor system, one of which was designed and operated for some time about forty years ago.
  • the individual carriers are attached to a pair or conveyor chains which are advanced intermittently to move the carriers along the tooling stations of the end conversion tooling, m synchronism with sets of reciprocating press rams/platens which close and open the tooling at the successive stations.
  • a lost motion type of connection between the carriers and the chains allows for substantial relative motion of the carriers, into and out of receptors which locate the carriers (ano tnus the shells and/or ends) relative + " o the upper and lower tooling.
  • Sucn connections inherently introduce play in the fore/aft connections by which the chains advance the carriers, thus slowing the operation and placing additional centering responsibility on the receptors for consistent proper alignment of the shells ano ends witn respect to the tooling at each station.
  • This system used spring finger for retaining parts m the carriers, similar to the retainers used m the aforementioned rotary systems.
  • the transfer conveyor system of the present invention utilizes a conveyor comprising at _east one continuous belt of reinforced flexible rubber-like material, with cogs or teeth on its underside and with a series of nests whicn fit into holes m the belt.
  • the nests are attached at their opposite edges to the positively driven, intermittently advancing, belt.
  • the belt is supported by and routed around an idler drum, located outside the press frame posts next to a down-stacker mechanism, and a drive drum located within the press frame adjacent the opposite frame posts.
  • the progressive end conversion tooling for ma ⁇ ng snells ..nto completed easy-open can ends is ⁇ ocate between the posts along (above and below) the upper and lower tooling sets.
  • the tab making tooling is preferably located between the drive drum and the other frame posts, and the carrying strip of formed tabs is routed back to the main tooling station where the tabs are applied to the ends.
  • the orive drum and idler drum are provided with circumferential tooth configurations which form a positive drive to the belt.
  • the press includes power take-off mechanisms which drive and synchronize the sneli feeding, tab strip feeding, and other mechanisms.
  • the attacnments between the nests and belt are located on transverse center lines (perpendicular to the path of belt travel), whicn attachments permit the generally flat and rigid nests to travel around the end turns of the belts, and to carry the parts within the nests about this turn. These attachments thus allow for limited and controlled relative movement between the nests and the belt, only in directions parallel to the plane of motion of the belts, but not in directions perpendicular (up and down) with respect to the belt upper surface.
  • the active (upper) flight of the belt is lifted and moved incrementally forward wnen the press is opened, to locate the nests successively in alignment with progressive stations of can end conversion tooling.
  • the flight is then lowered to locate the nests onto the lower tooling aligned precisely with respect to the tooling before it closes.
  • Each nest comprises a positive holding device in the form of a circular array of flexible fingers in a nest ring, which array engages shells firmly at their periphery and inhibits the shells from rotating or shifting between operations.
  • the shells are positively seated into the nests by applied differential air pressure, and then are mechanically positively seated into and firmly held by the circular array of independent stepped fingers as the nests are transferred through the conversion tooling.
  • After conversion the completed ends are carried around the drum at the end of the upper flight, and the ends are ejected from the nest rings and moved [as by force from air streams] along a table or chutes to conveyers familiar in end making facilities. These chutes thus receive the ends from the lower or return flight of the conveyor, providing a compact (end- to-end) conveying system.
  • this new belt transfer system preferably but not necessaryily usung multiple belts, lends itself to easier end size changes and even to running different sizes of ends in each lane. This is readily accomplished by attaching nests of different sizes in different ones of the lanes.
  • Fig. 1 is side view of the conveyor system, with portions of the parts in-feed and discharge and of the press polster, ram, and tooling, all shown schematically;

  • the press illustrated in Figs. 1, 2 and 3 is typical of a one hundred twenty five ton single acting press, and includes a bed 10, side frames including uprights or posts 12, 13, 14 and 15 defining side openings 16 and 17, and a crown 18 supported on the side frames.
  • the crank 20 is rotatably supported in the crown, has secured to it a flywheel 22, and is belt-driven by a drive motor 25 supported on top of the crown structure.
  • the crank is connected to the slide 30 by a pair of connecting rods (not shown) , and cooperative upper and lower end tooling sets, indicated by the general reference numerals 35 and 36, are mounted on the slide and on the bed, respectively.
  • the upper and lower tab tooling 37A fitted to the punch plate 38A which in turn is supported on the press slide 30, and lower or die tooling 37B, fitted to a bed plate 38B on the press bolster, is mounted in the press inside posts 13 and 17 and is supplied with a continuous strip of metal (in conventional fashion) from the rear of the press (Fig. 2).
  • the tab tooling may be of any desired type, an example being disclosed in U.S. patents 5,741,105 of 21 April 1998 and 5,799,816 of 1 September 1998, both issued to the assignee of this application.
  • crank 20 is fitted with a power take-off pulley 38.
  • a belt 40 transfers power from the crank pulley 38 to a pulley 42 connected to drive a shaft 45 which is mounted in suitable bearings supported outboard from posts 13 and 15, which are part of the right hand side frame of the press as viewed from the front (see Fig. 2).
  • Shaft 45 (see Fig. 3) is connected through a clutch and coupling 48 to a right angle intermittent drive unit 50, cf conventional construction, which in turn is connected through an output clutch to a shaft 53 supported in bearings and carrying a drive drum 55 which is rotated in timed intermittent fashion, synchronized with the rotation of the crank 20 and the motion of press slide 30.
  • a right angle intermittent drive unit 50 cf conventional construction
  • an idler drum 57 (Figs. 1 and 3) is supported in suitable bearings 58. Extending between the drums 55 and 57 is an endless conveyer belt 60, fitted with integral drive teeth 61.
  • the illustrated embodiment employs a single belt with three lanes, but it should be understood that parallel multiple belts, each with one or more lanes of nests, are within the purview of this invention.
  • the belt(s) is of the endless type, as later described, and is provided with multiple rows or lanes (e.g. three lanes I, II and III in the illustrated embodiment) of openings 62 (Fig. 4) which are regularly spaced to correspond to the spacing of the centers of the tooling stations.
  • these openings are nests 65 of a diameter such that ears 66 on the nests overlap the edge of the openings (Figs. 4 and 12).
  • the nests 65 are relatively light weight and generally rigid molded plastic parts and their spacing in the direction of motion of the belt and nests (see Fig.4) is equal to the spacing of successive stations of the tooling.
  • the nests 65 are placed in openings 62 along the lanes in belt 60 and attached to the belt by rivets or pins 67.
  • Shells deposited in the nests are carried by the belt through the tooling 35-36, in intermittent or step-wise fashion, synchronized to the operating strokes of the press.
  • Shells S (Fig. 12) to be converted are loaded onto belt 60 at the loading station indicated by general reference numeral 68 in Figs.l, 2 and 3, and the shells, when converted into finished ends, are unloaded from the nests at the unloading station indicated by the general reference numeral 70 (Fig. 1 and 5), and located at the beginning of the lower flight of belt 60.
  • the loading mechanisms are also referred to in the art as a down-stacker mechanism, in reference to the manner in which this mechanism removes single shells from the bottom of a supply stack and places a single shell S into each nest at the loading station 68 (Figs. I, 2 and 8).
  • the finished ends are ejected into discharge lanes or chutes, later described.
  • the series of ring shaped nests 65 (preferably circular; , are arrayed in lanes I, II and III, along flexible conveyor belt 60.

  • the bottom of the shell, including the lower end of ts chuck wall CW and the central panel P, is then located at the _ower edge of the nest with curl C between the lower rim surface 71 and fingers 75.
  • Fingers 75 are somewhat extended or opened m a radially outward direction during this process, and then the fingers close inward entirely around and over the snell curl C, so as to exert a centering force on the shell as it is loaded into the nest, and to hold _.t securely aoout ..ts entire periphery . This retains the snel ⁇ especially against turning while various operations are performed on it and a tap is attached to it, as the shell progresses througn the tooling stations.
  • a vacuum box 8 is located beneath the loading station and creates a differential in air pressure between the top and bottom of eacn shell as it is placed onto nests 65, thereoy placing or locating the shells onto the nests. Thereafter the shells are positively inserted into the nests and suosequently controlled by the nests; no further vacuum retention is needed as the snells progress through the tooling stations.
  • Belt 60 has rows of teeth or lugs 61 on its underside to mate with teeth 55T on driving drum 55 and 57T on idler and guiding drum 57.

  • the upper flight 60A of the belts is lifted upward by a spring biased lifter pad 84 when the press is opened, and the belts and attached nests 20 are moved incrementally forward over the lifter pad, to locate nests 65 successively in alignment with progressive tooling stations or sets 35, 36 of the can end conversion tooling (Figs. I & 2).
  • the lifter pad descends and causes the upper flight 60A to lower the nests therein, and the end shells S therein, onto the lower tooling 36 while pilot mechanisms (not shown) align the nests precisely with respect to the tooling before it closes.
