- the present invention includes a novel treating barrel which comprises a pair of spaced end members, a perforate body member extending between said end members and defining therebetween an internal substantially cylindrically shaped zone for receiving articles to be treated, said body member formed to define an opening therethrough extending longitudinally between said end members and being of a width less than about one-sixth of the circumference of said zone, and at least one tumbling rib extending along the interior surface of said body member between said end members and disposed substantially diametrically opposite to said opening, said tumbling rib projecting radially inwardly of said interior surface of said body member into said zone for imparting a cascading action to the articles in said barrel during oscillatory movement thereof, and means on said end members for supporting said barrel for oscillatory movement about an axis extending substantially longitudinally of said zone.
- the treating barrel of the present invention comprises a hollow, elongated body member, substantially circular in cross-secton, and two substantially flat end members disposed at each end of the body member to form an elongated, substantially cylindrically shaped zone for receiving articles to be treated.
- An elongated, coverless slot-like opening is provided in the body member which runs substantially the entire length thereof between the two end members.
- This opening desirably has a width which is not greater than about one-sixth of the circumference of the zone formed by the end members and the body member and preferably is about one-tenth to one-twentieth.
- the interior surface of the body member is provided with at least one longitudinal, raised projection or tumbling rib which extends into the enclosed zone, running substantially the entire length thereof and which is further disposed substantially opposite the elongated, slotlike opening in the body member.
- the tumbling rib preferably has substantially nonparallel sides which extend into the zone in a convergent direction and which form an angle with the body member which is desirably within the range of about 10 to 60 and preferably within the range of about 20 to 40.
- the barrel is formed with a single rib, the sides of which are substantially flat and converge within the zone to form a rib which is substantially triangular in cross section.
- the barrel is further adapted to be oscillated, rather than rotated, substantially around its horizontal axis during normal processing operation.
- the barrels of the present invention are particularly adapted for use in electroplating processes they may also be advantageously used in other processes, such as cleaning processes, painting processes, nonelectrolytic plating processes, as well as various other coating processes, and the like.
- the overall apparatus assembly for use with the novel barrels of the present invention, includes means for imparting the desired oscillating motion to the plating barrel.
- This means may include suitable reversable drive motors, reciprocating drive racks or rods, and the like, in combination with the necessary gearing and/or other connecting means for trans mitting the reciprocating motion to the plating barrel, so as to prevent full rotation of the barrel and discharge of articles therefrom during normal processing operations.
- the assembly includes suitable stops, clutches, and/or switches, or similar mechanisims for synchronizing the oscillating motion of the barrel with the drive mechanism, so that the barrel does not oscillate to a point at which the contents are discharged, except during unloading, regardless of the initial position of the barrel in the apparatus.
- Means may further be provided in the assembly for overriding the stops which limit the amount of oscillatory motion of the barrel so that, where desired, full rotation of the barrel may be efiected, as for example, at an unloading station.
- FIG. 1 there is shown a preferred embodiment of the present invention in which the barrel 1 is mounted in a suitable supporting frame comprised of the cross-beam 9 and the downwardly extending legs 11 secured thereto at their upper end.
- the barrel 1 is rotatedly mounted at the lower end portion of the legs 11.
- the supporting frame is further provided with a pair of outwardly extending arms 13, which are connected to the upper portion of the legs 11, which anns include lugs 15 which are adapted to coact with a suitable receiving fixture or saddle 17 mounted along the upper portion of a treating recepticle tank (not shown) for properly positioning the apparatus as it is placed in the treating receptacle.
- Electrical connections 19 are provided to the ends of the cathodes 21 which are disposed within the barrel and are also connected to the lugs 15 which, when disposed in contact with the receiving fixtures or saddles 17 can be electrified to provide the necessary current for electroplating of work pieces in the barrel.
- suitable support means for the barrel assembly may be used, such as a support having only a single saddle on each side.
- the barrel 1 is formed of a body member 3, and two end members and 7, secured to the body member to form an enclosed, elongated substantially cylindrically shaped zone for receiving articles to be processed.
- the end members 5 and 7 may be secured to the body member in any suitable fashion, as for example, by means of adhesive, welding, fasteners such as screws, or the like.
- the body member 3 is formed with a coverless, elongated, slot-like opening 2, which runs substantially the entire length thereof, between the end members 5 and 7. This opening provides the means whereby parts to be treated are introduced into and removed from the barrel.
- the width of this opening is desirably less than about one-sixth of the circumference of the zone formed by the end members and the body member and preferably is from about one-tenth to one-twentieth. Where the width of the opening is greater than this, it has been found that it is frequently difficult to oscillate the barrel enough, without discharging work pieces, to obtain the necessary amount of tumbling of the parts. With regard to the minimum width of the opening, this will be largely dependent on the size and type of parts to be processed so that in some instances, widths less than about one-twentieth of the circumference may be used. In general, however, in order to obtain the maximum benefits of improved solution interchange and increased path for electrical current flow, the width of the slot is desirably not less than about one-twentieth of the circumference.
- the body member 3 is provided with a plurality of perforations or apertures 4 which communicate with the interior of the zone or chamber to facilitate the passage of electrical current and/or the circulation of treating solutions into and out of the barrel.
- the size of each of these perforations or apertures will be limited to a size which is smaller than the size of the work pieces being treated in the barrel. Additionally, the relative spacing between the adjacent perforations or apertures will be restricted by the relative strength of the material from which the body member 3 is constructed.
- barrels of the present invention various materials of construction may be used for the barrels of the present invention, depending upon the type of process in which the barrel is to be used.
- the barrels are to be used in an electro process, such as electroplating, they are desirably made of an electrically non-conductive material, such as synthetic or natural hard rubbers, polyvinyl chloride resins, polymethyl methacrylate resins, phenol formaldehyde resins, polypropylene, and the like.
- the barrels are to be used in non-electrolytic processes, they may be constructed of metal, in any event, a wide variety of materials of construction may be used for the barrels, the only restriction being that the particular material utilized have the desired strength, resistance to corrosion and electrical properties for the particular process in which the barrel is to be used.
- the electrification of the pieces contained in the barrel may be effected by means of flexible electrodes or cathodes 21, which extend into the interior of the barrels.
- the flexible cathodes 21 are brought into the barrel through the end walls 5 and 6 of the barrel, as in conventional rotatable, horizontal plating barrels, as shown in FIG. 1.
- such electrodes may pass through the slot-like opening 2.
- the barrel of the present invention is formed with at least one raised projection or tumbling rib 6, which is disposed substantially opposite to the slotlike opening 2 in the body member 3.
- This tumbling rib projects into the material receiving zone of the barrel and extends substantially the entire length thereof.
- This projection or tumbling rib acts to lift the parts and cascade or tumble them as the barrel is oscillated, thereby assuring that the parts are constantly and evenly turned over as the barrel is operated.
- the size and configuration of the tumbling ribs must be such as to allow the parts being treated to slide off of the rib and tumble within the barrel when it is rotated to its extreme position.
- the size of the angle which the sides of the rumbling rib make with the body member is desirably within the range of about 10 to 60.
- This tumbling rib is preferably formed as an integral part of the body member 3, desirably by indenting the body member inwardly substantially opposite the slot-like opening, to form an elongated ridge,
- the apex of this ridge is disposed within the barrel or treating zone and the sides of the ridge form an angle with the body member which is within the range set forth above and preferably within the range of about 20 to 40.
- this angle might more correctly be described as the angle the sides of the rib make with the tangent to the body member, for convenience reference hereinafter will be made to the angle between the sides of the rib and the body member.
- the tumbling rib 6 may be a separate member which is secured to the body member 3, disposed opposite the slotlike opening 2 in the body member.
- the body member 3 may be formed so as to have more than one tumbling rib 6, which ribs are again disposed substantially opposite to the opening 2.
- a lip member 8 may be added to the slot like opening 2, which lip member is found in some instances to aid in the loading and unloading of the barrel.
- the tumbling rib may be in the form of a substantially fiat side.
- the lip member 8 may be used on any of the barrel configurations and that in addition to aiding in the loading and unloading of the barrel also helps retain parts in the barrel during treatment and acts to stiffen or strengthen the barrel as well.
- This lip may be substantially straight, as in FIG. 5 or curved, as in FIG. 6 and extends downwardly into the treating zone to a point which is substantially opposite the other edge of the slot-like opening. The specific length and curvature of this lip may vary so long as the opening between the edge of the lip and the edge of the slot is sufficient to effect the desired loading and unloading of the barrel.
- circumferential ribs or corrugations may also be provided in the body of the plating barrel.
- one or more partitions along the length of the barrel may be provided so as to divide the barrel into separate compartments.
- the configuration of the barrel may be further modified to provide a plurality of ribs formed over the entire body member and the shape of the body member may also be modified so that it is not completely circular. It is believed that further modifications, to accomplish substantially the same results, can be made to the shape of the plating barrels of the present invention and that these modifications will be apparent to those in the art.
- the barrels of the present invention when used in electroplating processes, the barrel is placed in a plating tank which contains a plurality of anodes, positioned so as to at least partially surround the barrel, in a known manner as with conventional rotating barrels.
- an internal anode may be used.
- Such anode may be mounted in any suitable manner so as to dispose the anode through the coverless slot-like opening in the barrel and position it in the desired manner inside the barrel.
- the internal anode may be used, either in place of, but preferably as a supplement to the conventional external anodes, thus making it possible to carry out various plating processes in the barrel, which have not heretofore been possible.
- the barrel of the present invention is adapted to be oscillated, rather than rotated, during normal processing operations.
- this oscillation is effected by means of a gear 10, mounted on the end member 7 of the barrel, and the gear train 12 mounted on one of the downwardly extending legs 11 of the barrel support frame.
- these are driven by the drive gear 16 on the motor 18, through the override clutch and gear mechanism 14.
- the clutch and gear mechanism 14 is mounted on the barrel carrier frame while the motor 18 is preferably positioned at the treating station, being mounted on the treating recepticle.
- the motor 18 is preferably a reversable electric or hydraulic motor which, during normal processing operations, will be periodically reversed so as to impart the desired oscillating motion to the barrel. This periodic reversal of the motor may be effected using any suitable control.
- the barrel 1 may be provided with a pair of stop blocks 20, which blocks will engage the stop plate 22 when it is in its processing position (1) as shown in FIG. 15.
- the stop blocks 20 are positioned on the barrel, with respect to the stop plate 22 so as to define the desired limits of the oscillating motion of the barrel.
- the override clutch and gear mechanism 14 will slip or override and the motor 18 is reversed, by means of suitable control switches and/or pressure sensing means, thus reversing the motion of the barrel.
- the stop plate 22 is spring loaded so as to hold it in its normal processing position (1).
- the stop plate 22 may be either manually or automatically moved to the unload position (2), so that it is no longer engaged by the stop blocks 20 on the barrel.
- an unloading cam 26 may be pro vided at the unload station, which cam will engage tabs 24 on the stop plate 22, raising it to the unload position (2) thus permitting the barrel to be fully rotated.
- the engaging plate or stop may also be mounted in the treating tank, rather than on the support frame.
- FIG. 7 through 11 Alternative configurations for the oscillating motion drive mechanisim of the overall apparatus of the present invention are shown in FIG. 7 through 11.
- a plating barrel of the present invention having a gear mounted on the end wall 7 of the barrel 1 and a gear train 12 mounted on the downwardly extending leg 11 of the barrel carrier frame.
- the uppermost gear of the gear train 12 is mounted on a shaft 25, which shaft is rotatedly mounted on the crossbeam 9 of the frame.
- a drive arm 27 is provided on the shaft 25 and is pushed by the contact member 31 on the reciprocating bar 29.
- the reciprocating motion of the bar 29 is effected by means of the motor 33, crank arm 35 and the crank link 37.
- the contact member 31 pushes the arm 27 in one direction, causing it to rotate and thereby effect the rotation of barrel in one direction, until the member 31 has raised the arm 27 to the point that it is no longer in contact with it.
- the contact member 31 again contacts the drive member 27 moving it and the barrel in the opposite direction until it has been raised to the point that there is no longer contacted by member 31.
- the amount of oscillation of the barrel is determined by coordinating the length of the drive arm 27 and the contact member 31.
- a spring type stop may be provided at the extreme positions of the drive arm 27 to move it slightly downward to insure that it will be in position to again be contacted by the member 31.
- FIG. 8 A similar type of drive mechanism is shown in FIG. 8 except that the barrel is provided with only the gear 10 which is driven by the partial gear 39.
- a shafl 25 is operably connected to the partial gear 39, which shaft is driven by means of the drive arm 27, in the same manner as the apparatus shown in FIG. 7B.
- the barrel may be provided with a pivoted drive arm 45 which fits into a sloted drive head 47.
- the desired oscillatory motion is imparted to the barrel.
- the oscillation of the drive head 47 may be eflected using any convenient means, such as a reciprocating rack, a drive arm and reciprocating bar, or it may be driven by a reversable electric or hydraulic motor, either directly or through a slipping or overriding clutch mechanism, as has been heretofore indicated.
- FIG. 11 Still another alternate embodiment of the drive mechanism which may be used in the overall apparatus assembly of the present invention is shown in FIG. 11.
- a rack 41 and pinion 43 which drive a gear train 39 to effect the oscillation of the barrel, through the gear 10.
- the rack 41 is driven by means of the motor 33 through the connecting arm 35 and connecting link 37.
- a partial gear may be substituted for the straight rack 41.
- an important feature of the overall apparatus assembly of the present invention is the means for limiting the amount of oscillation of the barrel during normal processing operations, such as an electroplating operation.
- These mechanisms may be formed as a part of the barrel itself, as with the stop members as shown in FIGS. 15 and 16, or they may also be a part of the drive mechanism itself, as with the reciprocating bar type of mechanisms as shown in FIGS. 7 through 10. In general, it has been found to be preferably to have these mechanisms limit the amount of movement or oscillation of the barrel so that it is not substantially in excess of about 180".
- oscillation of the barrel in an amount greater than 180 may be effected without the discharge of the parts.
- this may require that the barrel be loaded to less than its nonnal capacity, i.e., less than about two-fifths full, which operation may not be economical and hence may not be desired. It is for this reason that it is generally preferred that the amount of oscillation of the barrel is restricted so that it is not substantially in excess of about 180.
- Another important feature of the overall assembly apparatus of the present invention is the provision for means of synchronizing the oscillating movement of the barrel with the oscillating drive mechanism so that, regardless of the position in which the barrel is placed in the drive mechanism, the barrel will not be oscillated to a point at which the parts being treated will be discharged into the treating tank, during the normal processing operation.
- Such features are incorporated in the various driving mechanisms and barrel configurations as have been described hereinabove. For example, in the drive mechanism as shown in FIGS.
- the barrels be capable of being fully rotated when they are to be unloaded.
- the barrels are provided with positive stop members, as in the configuration shown in FIGS. 15 and 16, this may be accomplished by having these stops spring loaded, as shown in these figures, so that they may be manually or automatically moved out of position when the barrel is put into an unloading station.
- this unloading may conveniently be accomplished by using the conventional rotary drives as are commonly used with conventional rotating horizontal barrels. This unloading operation may involve rotating only the barrel itself or, if desired, may involve the rotation of the entire barrel assembly or super-structure, as by rotating the superstructure 90 and then oscillating the barrel to unload it.
- the barrel 77 of present invention including its superstructure 75 is supported by a suitable hoist member 73.
- This hoist member may either be manually or automatically operated.
- This assembly is transported by a suitable conveyor 71 through a load station 61 wherein the parts to be treated are loaded into the barrel from a movable hopper 69.
- the barrel assembly is then moved to a treating station 63 wherein it is lowered into a treating tank 79, as for example, a tank for electroplating.
- the barrel is oscillated by means of a suitable oscillation effecting mechanism, such as has been described heretofore.
- the assembly is then moved to an unloading station 65 wherein the barrel is completely rotated so as to empty the treated parts into a receiving hopper 81.
- the loading and unloading of the barrel may be accomplished in a single station.
- the barrel assembly is brought into the station and is loaded by means of a suitable hopper.
- the loaded barrel is then transported through the various treating stations in which the desired processing of the work is effected.
- the barrel is returned to the first station, shown in FIG. 13, wherein the barrel is rotated to discharge the load onto a suitable hopper or other conveying means.
- the barrel is returned to a load position so that it can again be loaded by means of the hopper.
- the barrels of the present invention are particularly adapted for carrying out this operation in a fully automated system, these operations may also be carried out in a system which is at least partially manually operated.
- the treating stations through which the barrel is passed may include a station in which the load in the barrel is subjected to various treating sprays and/or a station in which drying of the load is effected.
- the desired treating spray or drying gas such as hot air
- the desired spray or drying gas is injected through the open mouth of the barrel as it is oscillated in the station.
- the barrel is placed either automatically or manually, in the desired spray or drying station and oscillated.
- Hot air for drying or liquid sprays for various cleaning or rinsing treatments are then directed into the coverless slot-like opening of the barrel so that as the load is tumbled, all parts thereof are contacted with the spray or drying air.
- nonles may be provided to pump or inject solution into the open mouth of the barrel as it is oscillated.
- both the rate and degree of oscillation of the barrels of the present invention may be easily controlled by means of suitable timing devices and by adjustment of the oscillation mechanism so that a change in amount and degree of tumbling of the parts being treated is obtained.
- mixed loads of different types of parts may be treated at the same time.
- the plating barrels of the present invention are found to provide further advantages over the conventional rotating horizontal barrels, in that by having a slot-like opening rather than a door, which is essential for the rotating barrels, there can be more interchange of solution in the barrels when they are submerged, and in electroplating processes, there is more path for current flow. Additionally, the open mouth in the barrel allows for the pumping of solutions or gases into the barrel if this is desired in the particular processing operation. The absence of doors and their necessary clamps or fastenings, also results in less solution dragout.
- the substantially circular cylindrical shape of the barrel also is advantageous over the convention hexagonal shaped rotating barrels in that the cylindrical shape provides for greater surface area for perforations for the passage of current and the interchange of solution and greater spreading of the load can be achieved. Additionally,
- the present invention also includes an improved method for electroplating articles in bulk.
- the articles to be plated are placed in a coverless, open mouthed plating barrel.
- the barrel has electrode means disposed therein, in contact with the articles to be plated.
- the barrel is immersed in an electroplating solution so that anodes are disposed around the exterior of the barrel when it is thus immersed.
- the barrel is then oscillated through an angle which is not in excess of about 220 and preferably is not substantially in excess of about 180.
- the desired tumbling and turning over of the workpieces may be accomplished by providing the plating barrel with suitable tumbling ribs. Additionally, this plating process may be carried out as a part of an overall treating process in which the processing of the parts from loading of the barrel, through the various treating stages of cleaning, rinsing, plating, coating and/or drying, to unloading of the barrel may be effected substantially automatically.
- An apparatus for treating articles in bulk comprising a framework and a treating barrel supported thereby, said treating barrel including a pair of spaced end members and a perforated body member extending between said end members and defining an internal cylindrically shaped treating zone, said body member formed with a longitudinally extending opening of a width less than about one-sixth the circumference of said zone and at least one tumbling rib disposed in the interior of said zone substantially opposite to said opening, means on said end members for supporting said barrel on said framework for rotation about an axis extending substantially longitudinally and centrally of said zone, and coacting stop means on said barrel and said framework selectively positionable in an operative position for restricting angular rotation of said barrel and an inoperative position enabling unrestricted rotation of said barrel in either direction, said stop means oriented relative to said opening in said barrel to limit rotary movement thereof when disposed in said operative position in either direction between an angularity of at least about 180 up to an angularity below that at which articles are discharged from said opening.
- coacting stop means include a pair of stop blocks fixedly mounted on one of the end members of said barrel and an engaging member movably mounted on the framework supporting said barrel and selectively positionable in said operative position and said inoperative position.
- electrode members are disposed within the treating zone formed by the body member of the barrel so as to be in contact with the articles to be treated which are contained within the zone.
- An apparatus for treating articles in bulk comprising a treating receptacle and a work carrier adapted to be disposed at said treating receptacle during the treating operation, said work carrier comprising a framework and a hollow cylindrically shaped perforate treating barrel including a pairof spaced end members and a perforated body member extending between said end members and defining an internal cylindrically shaped treating zone, said barrel mounted on said framework for rotation about an axis extending substantially longitudinally and centrally of said treating zone, said treating barrel being formed with an elongated opening extending longitudinally of the end portions there of of of a width less than about one-sixth the circumference of said zone through which articles to be treated are loaded into and unloaded from said barrel, at least one tumbling rib disposed in the interior of said zone substantially opposite to said opening, supporting means at said receptacle for supporting and retaining said work carrier in appropriate position relative thereto, drive means for oscillating said barrel when said work carrier is appropriately positioned at said receptacle, and coacting
- At least one of said treating receptacles includes a treating tank for containing a treating solution and means are provided for injecting treating solution into the opening in the barrel as it is oscillated beneath the level of the treating solution.
- At least one of said treating receptacles includes means for injecting a drying gas into the opening in said barrel while the barrel is oscillated in said treating receptacle.
