Description

SPINDLE DISC FOR HIGH SPEED CANS DECORATORS FIELD OF THE INVENTION This invention relates in general to apparatus for applying decorations in cylindrical containers and,. in particular, it relates to a spindle carrying disk for such a continuous high-speed motion device.

BACKGROUND OF THE INVENTION The teachings of U.S. Patent No. 3,766,851 issued October 23, 1973 to E. Sirvet et al. Are incorporated herein by reference. for "Continuous Can Printer and Handling Apparatus", U.S. Patent No. 4,140,053 issued February 20, 1979 to J. Skrypek et al. for "Mandrel Mounting and Trip Mechanism for Continuous Motion Decorator" and United States Patent No. 5,111,742 issued May 12, 1992 to R. DiDonato et al. for "Mandrel Trip Subassembly for Continuous Motion Can Decorators". U.S. Patent No. 3,766,851 discloses relatively high speed apparatus for applying decorations to the cylindrical container exterior, while these are mounted on mandrels or spindles, which are located at P1758 / 99MX along the periphery of a large disk-type carrier that rotates continuously. Decorations or decorations are applied to the containers by causing them to engage a rotating or rotating blanket of a decorator that is adjacent to the periphery of the carrier. During the coupling between the containers and the decorative blanket, the containers follow the surface of the blanket through the region in which the containers and the surface of the blanket are coupled. To achieve this tracking, for each angular position of the container, measured around the axis of the spindle disk as a center, a device controlled by a closed loop or box cam keeps the container in a precise radial position with respect to the axis of the spindle disk . This type of decoration equipment includes some relatively heavy elements that move at high speed. Because there must be precise coordination between the various elements, inertial forces, lubrication and useful power are important considerations of engineering design, such as downtime in the equipment, maintenance costs and installation procedures.

SUMMARY OF THE INVENTION In accordance with the present invention, P1758 / 99 X each of the mandrels or spindles is part of an individual spindle unit that includes an L-shaped base that must be relatively rigid to properly locate the cantilever spindle while the decorations are applied to the container carried by the same. To achieve this, the present invention significantly reduces the weight of the base of the spindle unit without sacrificing stiffness. Furthermore, the bending moments that must be resisted by the cantilever spindle are significantly reduced by reducing the spacing between the axis of the spindle and the rods extending from the base to guide the spindle unit as it makes a movement reciprocating radially. These serve to reduce the stress on the bushings or bearings, where the guide rods perform a reciprocating movement, so that the wear of the bushing or bearing is reduced. As will be seen below, improved lubrication is also provided between the guide rods and their bearings. Many prior art spindle discs were provided with a large chamber from which the lubricant was removed and pumped through longitudinal passages in the radial guide rods of the spindle units. To reduce the weight of the spindle disc, the large chamber of the large lubrication reservoir, P1758 / 99 X required in many spindle discs of the prior art has been removed. Instead, a multitude of interconnected, relatively small lubrication chambers is provided. This serves to reinforce the spindle disk. That is to say, in the prior art such a large amount of material was removed to form the large lubrication chamber that the resistance of the disc had to be restored by providing the chamber with a relatively large, thick and heavy steel lid. In contrast, the plurality of relatively small lubrication chambers of the present invention are interconnected by an annular groove of small cross section. This groove is formed practically without reducing the resistance of the spindle disc, so that a light aluminum cover is satisfactory to close the connection slot and the small lubrication chambers. According to the above, the main object of the present invention is to provide an improved decorator of cylindrical containers of continuous movement and high speed, which achieves important reductions in maintenance and energy requirements. Another object is to provide a decorator of this type, where significant weight reductions have been achieved in the disc-type carrier and in the reciprocating, lead screw subunits.

P1758 / 99MX by the same. Another additional object is to provide a construction of this type of decorator to simplify the installation and start-up procedures and reduce the likelihood of lubrication points that have not been properly treated or have been completely bypassed. A further object is to eliminate the telescope-like displacement of the arrow and the bearing connections in the air / vacuum lines. A further object is to provide a spindle disc construction, wherein a hose having therein a single complete loop is used to connect a spindle unit which reciprocates radially to a radially fixed point in the disc of the spindle. spindle A further object is to provide a spindle disk construction in which the hose connections are made by connectors or connections that do not have movable parts. These objects, as well as other objects of this invention will be readily apparent upon reading the following description of the accompanying drawings, in which: P1758 / 99MX BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a front elevational view of a continuous motion can decorating apparatus, including a spindle disc unit constructed in accordance with the teachings of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES Referring now to the Figures and, more particularly, to Figure 1, which illustrates the continuous motion cylindrical container decorating apparatus of the general type described in the aforementioned US Pat. No. 3,766,851 and Patent. of the United States No. 5,111,742. The apparatus of Figure 1 includes a feed conveyor gutter 15 receiving the undecorated containers 16, each one being open in P1758 / 99MX one end thereof, coming from a supply (not shown) and placing the cans 16 on arched supports or cavities 17, formed by depressions aligned on the outer edges of separate rings 31, 32 (Figure 2). The latter are fixedly secured to the disk-type spindle carrier 18, which is wedged to the horizontal drive shaft 19. An accessory comprising concentric rings 45 and 64, separated by angular spacers 48, is interposed between the rings of the cavity 31, 32 and the carrier 18. The screws 46 secure the ring 45 against the front surface 65 of the carrier 18 and screws 47 mount the cavity rings 31 and 32 in the ring 64. The latter It has a larger diameter than the ring 45 and is placed in front of it. The spindles or mandrels 20 that extend horizontally (Figure 2) are also mounted on the carrier 18, wherein each mandrel 20 is in a horizontal alignment separated from an individual cavity 17, while passing through a short or short region that is extends downstream from the feed conveyor 15. In this short region, the undecorated cans 16 are moved horizontally backwards by a baffle (not shown), are transferred from each support 17 to an individual mandrel 20. The suction applied by means of of an axial passage that extends to the P1758 / 99 X further or front end 20a of the mandrel or spindle 20, withdraws the container 16 backward (leftward with respect to Figure 2) to the final position of seating in the spindle 20. While mounted on the mandrels 20, the cans 16 are decorated by being placed in contact with the mat, or continuously rotating image transfer blanket, of the multi-colored printing press decoration section, generally indicated by reference numeral 22 After this and while mounted on the mandrels 20, each decorated can 16 is coated with a varnish protective film applied thereto when engaging the periphery of the applicator roll 23 in the over-varnishing unit, indicated generally by the number 24. The cans 16 that in them have decorations and protective coatings are then transferred from the spindles 20 to the suction cups (not shown), mounted near the periphery. a of the transfer wheel 27, while the latter rotates around the arrow 28 as a center. The cans 16 carried by the transfer wheel 27 are deposited on generally horizontal bolts 29, which project from the chain type output conveyor 30, which transports the cans 16 through a curing oven (not shown). For that moment, spindle 20 moves more P1758 / 99 X there at the downstream end of the gutter 15 and is in the vicinity of the detector 33, each spindle 20 must be properly loaded with a can 16. If the detector 33 detects that a spindle 20 is unloaded or not loaded suitably, then before this particular spindle 20 enters the decoration zone, where the printing blanket 21 normally engages the can 16 in the mandrel 20, this spindle 20 discharged or poorly loaded, moves to a position moved or displaced, that is, a "non-printing" position. As the displaced mandrel 20 moves through the decoration zone, it will be separated from the periphery of the blanket 21. This non-printing position is achieved by controlling the double-acting cylinder 34 to move the sub-frame 35 which in it has mounted to the arrow 19 of the spindle carrier, moving the sub-frame 35 to the left with respect to Figure 1, while the main base 36, to which the printing unit 22 is mounted, remains stationary. In addition, the action of the detector 33 causes the overmoulding unit 24 to move downwards with respect to the arrow 19 that carries the spindle, so that the displaced spindles 20 are not coupled to the overbanding application roller 23. The spindle 20 is part of the spindle subunit 40 (Figure 9) which also includes a base 41 P1758 / 99MX with L-shape, a short arrow 44, two guide rods 51, 52 and two cam follower rollers 57, 58. In lateral elevation (see Figures 11 and 13), the base 41 includes the main section 42 horizontal and the arm 43 projecting radially outwardly from the main section 42, being at the rear of the. same and perpendicular to it (Figure 3). The guide rods 51 and 52 extend radially inward from the main section 42 and are secured by the respective screws 54 and 55, which extend through the openings in the plate 53 and are received by the threaded openings 151 and 152 in the ends radially outwardly of the respective rods 51 and 52. Four screws 56 extend through holes in the plate 53 and are received in screw form by the openings 123 in the base 41 to secure the plate 53 against the surface radially outward from the main section 42. The retainer or retainer 59 on the rear of the arm 43 secures the spindle supporting the arrow 44, so that it extends perpendicular to the arm 43 at a position radially further away from the section. 42 and overlays the latter. The followers 57 and 58 are mounted rotatably by the retainer or detent 61 at the rear of the main section 42 and travels on the closed cycle cam track 62 that surrounds the P1758 / 99 X Spindle disk arrow 19. In a manner known in the art, the cooperation of the cam 62 and the followers 57 and 58 controls the radial separation between the rotational axes defined by the parallel arrows 19 and 44. Figures 5 and 6 illustrate the bare or uncovered spindle disc 18, which is provided with a central opening 66 that receives the driving arrow 19. A key or wedge 67 (Figure .2) is received by the slot 68 (Figure 5) in the wall defining the opening 66 to provide alignment and the ring feeder 144 provides a driving connection and stroke adjustment between the carrier arrow 19 and the spindle disk 18. The latter assembles twenty-four spindle subunits 40 according to is partially shown in Figure 4, where there are equal angular separations between the subunits 40. These spacings are established by a pair of radial holes 73 and 74 extending inwardly from the periphery of the Disc 81 and housing the respective cylindrical bearings 71 and 72 (Figure 2). The reciprocating guide rods 51 and 52 extend through support passages that are provided by the respective bearings 71 and 72. Extending in front of the rear surface 75 of the carrier 18 and ending shortly after the front surface 65, there are twelve axial bores 76, of which each P1758 / 99MX communicates with a pair of holes 73 and 74 that are in the same angular position and a second pair of holes 73 and 74 that are in an adjacent angular position. In this way, each axial bore 76 intersects four radial holes 73, 73, 74 and 74 at the ends radially inward of the latter. A small transverse circular slot 77 milled on the rear surface 75 interconnects the twelve holes 76. The sizes and locations of the holes 76 and 77 are such that they do not have a significant effect on the strength of the carrier 18. Thus, the aluminum ring 78 (Figure 3), supported by screws 79, functions only as a grease retaining cover within holes 76 and slot 77. It is not necessary that cover ring 78 be constructed of heavy reinforcing material the resistance of the carrier 18 bare or uncovered. Each bearing 71 and 72 are retained in a respective radial hole 73 and 74 by a ring-shaped individual cover or bracket 80 (Figure 3). The supports 80 are at the radially outer ends of the bearings 71 and 72 and the radially inner ends of the bearings 71 and 72 rest on the inner edges of the holes 73 and 74. Each support 80 contains two ring seals 82 and 82 which surround each guide rod 51 and 52. Three screws 83 which are received by the openings 84 P1758 / 99MX (Figure 8) on the periphery 81 of the carrier secure each support 80 to the carrier 18. The guide or driving of the upper ends of each bearing 71 and 72 in the annular undercut 99 of the radially internal surface of the support 80 places in Precisely form the seals 82 and 82 from below the support 80 with respect to the support passages provided by the bearings 71 and 72 to obtain an improvement in the operation of the guide rods 51 and 52, as they effect the reciprocating movement in the passages of bearing support 71 and 72. Each of the twenty-four openings 86 (Figure 5) on the front surface of the carrier 18 receives an individual accessory 85 (Figure 2). When this can decorating apparatus is being installed for operation, grease injected into the accessory 85 travels a circuit path to vent or discharge the fitting 87 into the opening 88 (Figure 8), at the periphery 81 of the carrier. With particular reference to Figure 3, it is noted that this circuit path from the accessory 85 to the accessory 87 includes an axial portion 91, an annular cut 92 inside the bearing 71, an axial portion 93, a cut 94 inside the bearing 72, an axial portion 95 and a radial portion 96. The zig-zag grooves 97 in the inner surfaces of the bearings 71 and 72 extend from the cuts 92 and 94 to both ends of the bearings P1758 / 99MX 71 and 72. Thus, when the grease introduced into the accessory 85 appears in its associated relief fitting 87, this is a positive sign that luu d and rods 51 and 52 of a subunit are lubricated. particular spindle 40. As required, the vacuum and pressure are supplied to the front end 20a of the mandrel 20 through a single flexible hose 101 having opposite ends attached to the connections 102 and 103 which are respectively connected to the carrier 18 and the spindle unit. 40. That is, the straight connection 102 is screwed into an opening of the movable valve member 104 which is secured by screws 107 to the front side of the carrier 18 and the L-shaped connection 103 is screwed into the opening 108 of the base 41 The opening 108 is at the forward end of the main section 42 (see Figures 9-14). The wear plate 106 secured to the front of the movable valve member 104 is in a sliding engagement with the stationary valve member 105 at the interface 109. In a manner known in the art, the appropriate openings in front of the valve members 104 and 105 enter alignment at particular angular positions of the carrier 18, so that at appropriate times, the vacuum and pressure levels that are supplied to the inlet side of the stationary valve member 105 (remote side of the valve member) P1758 / 99 X 104) extend through the valve members 104 and 105 to appear on the mandrel unit 40. To prolong the life of the hose 101, the connections 102 and 103 have no parts that are free to swing or move in some other way with respect to each other, once the connection 103 is secured to the mandrel subunit 40 and the connection 102 is secured to the movable valve member 104. In addition, the hose 101 contains a complete loop of diameter relatively large and the connections 102 and 103 are angularly displaced, so that the hose 101 will not rub against itself as the connection 103 effects a reciprocating movement radially. In addition, the hose 101 is positioned so that it will not be fired against other elements. The main section 42 of the base 41 is provided with an axial passage 110 which extends rearwardly from the opening 108 to the radially internal end of the passage 111 in the arm 43. The passage 112 extends to the edge radially outwardly of the arm. 43, wherein the radially outward end 109 of passage 111 is capped. The elongated opening 112 at the midpoint of the passage 111 connects with the opening 113 of the arm, which houses the rear end of the arrow 44 of the mandrel. The passages (not shown) extend from the opening 113 to connect with the end P1758 / 99MX front 20a of the mandrel 20. The arm 43 is also provided with a passage / 114 extending to the recess 116, where one end of the short arrow 61 is placed (Figure 2). To lubricate the cam follower rolls 57 and 58, grease 114 is introduced into the radially outer end 117 of the passageway 114. The guide rods 51 and 52 pass through the openings 121 and 122 extending radially through the main section. 42 and four openings 123 on the radially outer surface of the main section 42 receive the screws 56 securing the base 41 to the plate 53 which supports the guide rod. The base 41 weighs considerably less than the base 119 of the prior art shown by the dashed outline of Figures 13 and 14 and other mandrel support bases that can be replaced by the base 41. That is, the base 41 does not include to the sections between the solid line and the dashed outline of Figures 13 and 14, while the base 119 of the prior art includes the sections most practically the entire base 41. It is noted that for the base 41, the resistance to the bending or bending between the arm 43 and the main section 42 is maintained at a satisfactory level by thin triangular brackets 126 (Figure 9), which provide the reinforcement on each side of the arm 43, where it joins the section P1758 / 99MX main 42. The base 41 is not only lightweight but, the main section 42 is relatively thin, so that the rotational axis of the mandrel 20, located in the center A (Figure 2) of the cantilevered arrow 44 can be relatively close to the radially outward ends of the bearings 71 and 72. This serves to reduce the bending moments acting on the guide shafts 51 and 52 and which result in bending forces which cause rapid wear of the teeth. bearings 71 and 72 in the constructions of the prior art. In a practical embodiment of the apparatus constructed in accordance with the present invention for decorating two-piece cans, wherein the mandrel 20 has an approximate diameter of 2.6 inches, the spacing measured radially between the rotational axis A to the mandrel 20 and the radially outer ends of the bearings 71 and 72 is as little as 5.2 inches, wherein the cam groove 62 is shaped and positioned so that for each revolution of the mandrel carrier 18 the axis A travels through a radial stroke of 3 inches. Although the present invention has been described in relation to particular embodiments thereof, many other variations and modifications as well as other uses will be apparent to those skilled in the art. Therefore, it is preferred that the P1758 / 99MX present invention is limited not by the specific disclosure of the present but only by the appended claims.
