- the articles are treated in the tank assembly l0 and then are delivered, as presently described,
- tank assemblies 10,-11 as well as the other tank assemblies 12 in the system are of substantially identical construction, as 'will be hereinfater described, except that where electrical power is required for plating, additional provision is made for the application of such electrical power.
- each tank assembly is working or performing a function on a batch of the articles while the other tank assemthe articles.
- the successive tank assemblies perform the functions designated, namely, cleaning, electrically cleaning, water treatment or rinsing, acid rinse, reclamation of acid, plating, reclaiming the plating solution, water rinse, dipping for surface treatment, water rinse, hot water rinse and drain, before passage out of the system.
- chutes 13 are provided as presently indicated.
- each tank assembly l12 as well as additional tank assemblies in the system, which are not shown, is substantially identical in construction except for the inclusion or omission of the electrical components for applying power.
- each tank assembly -12 includes a container or tank 14 which is adapted to hold the treating or plating liquid, as the case may be.
- Each tank assembly further includes a barrel 15 that is generally cylindrical and includes an outer cylindrical wall 16 and annular flat radial end walls 17 (FIGS. 6, 7).
- the barrel 15 is made of plastic material such as polypropylene and the walls 16, 17 are formed with holes 18 to permit the ready passage of liquid therethrough.
- each barrel is rotatably supported in its respective tank by an arrangement which includes spaced pairs of levers 20 that are pivoted alongside the ends of. the barrel on shafts 21 rotatably mounted on brackets 22 intermediate the ends of the levers 20.
- Opposed levers 20 rotatably support rubber faced drive rollers 23 at one end and idler rollers 24 at the other, the drive and idler rollers on each lever 20 engaging the drum at circumferentially spaced points.
- the drive rollers 23 are driven by sprockets 24 on the shafts 25 of the drive rollers 23 which extend between opposed levers 20.
- An endless-chain 26 is trained so that the drive rollers are driven simultaneously.
- Aother sprocket 27 onone of the shafts 25 is driven by a motor M mounted on an extension 28 of the lever arm 20a so that the motor M is exteriorly of the tank in order to avoid contamination of the tank from liquid and other matter as the motor operates.
- Each arm 20 is adapted to engage an adjustable stop 30 on the tank.
- the barrel 15, as heretofore described, comprises cylindrical outer wall 16 and spaced radial walls 17 of plastic material such as polypropylene each of which is provided with a plurality of openings 18 therethrough.
- the walls are welded to one another to form a unitary structure.
- Baffles 31 also made of plastic material extend transversely between the spaced radial walls 17. The outermost portions of the baffles 31 are provided with holes 32 therethrough to minimize the tendency for liquid to collect and be trapped so that the liquid will not be transferred from one tank to the other during rotation of the barrel thereby obviating contamination of the liquid of one tank with that of the other.
- an annular member 33 is mounted at the juncture of the inner surfaces of the wall 17 and wall 18. These walls 33 are also wardly toward the liquid in the tank.
- An annular bead 36b is provided on the outer surface of radial walls 17 adjacent the next successive tank to prevent liquid on said outer surface from passing downwardly onto the electrical connections below.
- Each barrel includes a plurality of baffles 31 that extend at an acute angle A with respect to the inner surface of wall 16, the angle A ranging between and 55, and being preferably Where electrical power is required to be applied to the liquid in order to perform a plating function, a metal plate 37 is provided on preferably all the baffles so that as the barrel rotates, at least three metal plates 37 are within the liquid at all times.
- Each baffle plate 37 comprises electrically conductive plate such as titanium or the like which includes a flange 38 engaging made of plastic material.
- Walls 33 include inner annu- I lar surfaces 34 that taper radially inwardly away from the center of the drum and function to keep the parts from lodging between the chute and the walls of the barrel.
- each barrel is provided with axially extending portions 36 along the inner periphery defining the openings and an annular bead 36a is provided on the outer surface thereof to cause liquid draining along the inner surface of the radial walls 17 to be directed downthe inner periphery of each baffle.
- Each plate 37 is positioned in a recess 39 in the baffle 31 so that the surface of plate 37 is flush with the exposed surface of baffle 31. Adjacent pairs of baffles 37 are electrically interconnected by arcuate metal portions 41 and radial copper members 42 extend, covered by a layer of plastic 42a (FIG. 18), to brackets 42!; which are electrioted to arms 46, 47.
- the arms 46 are pivoted to a lever- 47 that is maintained in adjustable angular position on the tank by a turnbuckle 48.
- a spring 49 extends between the pivots of the arms 45, 46 to one another to yieldingly urge the brush member 44 against the outer periphery of the bus bar 43. In this manner, the brush member 44 is maintained in contact with the bus bar 43 but is spaced vertically above the tank to minimize any tendency of the liquid to contact the electrical parts. Electrical current is supplied to the brush 44.
- the anode for plating is provided by an anode retainer in the form of a helical coil spring 50 in which the anode balls 51 are placed.
- a bracket 52 holds spring 50 in an arcuate configuration.
- a stop 52a on bracket 52 closes one end of the spring 50 and engages transverse bars 53 in the tank while a bracket arm 54 hooks over an electrical bar 55 for providing the other electrical lead as needed. In this manner, a large anode area is provided in close proximity to the periphery of the barrel.
- a handle 56 on bracket 50 facilitates removal and replacement.
- each chute 13 comprises sections or portions 60, 61 pivoted to one another. Portion 60 forms a greater angle with the horizontal than a portion 61.
- the chute 13 further flares from a wide transverse section 62 adjacent the upper end within the tank to a narrow section 63 at the adjacent tank to which the parts are fed (FIG. 9).
- the chute includes flared portions 64 at its upper end within the tank as shown in FIG. 9 which extend upwardly and forwardly to assist in collecting the parts and directing them downwardly during the transfer when the barrel rotation is reversed.
- the chute section 60 includes a pivoted portion 65 that has V-shaped drain slots 66 therein. Chute portion 65 is normally positioned in the broken line position exposing opening 66 a so that parts will be returned to the barrel and be prevented from passing to the adjacent barrel when the barrel is rotated in the normal running direction. A secondary wall or scoop 66a is provided beneath slots 66 and tapers downwardly and inwardly to guide the liquid passing through slots 66 to the interior of barrel 15. The exterior or lower surface of chutes 13 is coated with a plastisol which functions to reduce noise while the upper surface is uncoated to facilitate movement of the articles being treated. The section is pivotable by a linkage including a cylinder 67 which acts through a lever 68 fixed to chute portion 65.
- an arcuate cover 60h is mounted on the chute.
- the modified tank assembly shown in FIGS. -12 may be used which is substantially identical to other tank assemblies except that wherein a pump 70 exteriorly of the tank 14 functions through pipes 71, 72 to feed the liquid for any prescribed period to both ends ofa transverse or axial pipe 73 provided with nozzles 74 which direct the liquid downwardly onto the parts.
- the functank assembly is either treating articles or delivering articles to the next successive tank assembly.
- the number of tank assemblies for any particular operation depends upon the amount of time required for that treatment. Thus, a tank assembly is provided for the shortest needed treatment. Then if there is another treatment that requires a greater length of time, that particular treatment utilizes two or more tank assemblies so that a portion of the treatment occurs during one cycle of the tank and another portion of the treatment occurs in the other tanks.
- a forward master timer and a reverse master timer are associated with the first tank assembly and control respectively the forward and reverse rotation of the barrel of this tank assembly (the first barrel).
- a timer is associated with the barrel of each subsequent tank assembly and is electrically interlocked with the barrels of the immediately preceding and succeeding tank assemblies.
- the forward master timer controls the operation of the first barrel in the forward direction for a preselected forward cycle time after which the reverse master timer controls the operation of the barrel in reverse for a preselected reverse cycle time.
- Such a forward-reverse cycle is automatically repeated for each batch of articles.
- the timer for the barrel of the next successive tank assembly (the second barrel) is initiated through an electrical interlock which runs the second barrel forward for a preselected time and then in. re-
- tioning of the pump 70 may be timed to any lesser time less than the total time that the parts are in the drum.
- the liquid level in the tank is below the lower end of the barrel.
- a vibrator 77 is provided on the arm and vibrates during this rotation of the barrel to vibrate the drum.
- the conveyor is actuated to feed articles to the metering hopper.
- the metering hopper in turn periodically feeds a batch of articles to the first tank asstarts the timer for the barrel of the third tank assembly. This same interlocking arrangement is. repeated between succeeding'barrels).
- the combined forward and reverse cycle times of each barrel are identical.
- the barrel of each drum rotates in a clockwise direction as viewed in FIG. 6 to cause 'a tumbling and agitation of the parts.
- the pivoted portion 65 is in the down or broken line position (FIG. 8). Any parts that may inadvertently be delivered to the chute 60-are returned back through the opening in the chute to the tank by the pivoted portion 65. Further, any liquid delivered to the chute 60 inadvertently will be directed through the opening provided by the downward position of the portion 65away from the chute to the interior of the tank.
- the annular beads 36a function to minimize any' tendency of the liquid on the interior surfaces on the wall 17 to pass out of the opening at the center thereof. Further, the annular bead 36h prevents liquid from contacting the bus bar.
- the desired current is provided by the plates 37.
- the arrangement of the plates and associated conductive plates at 41, 42 recessed in corresponding grooves provides for a smooth surface on the interior of the barrel as well as on the baffles 31.
- the tapered surface 34 prevents parts from collecting at the corners and thereby minimizes the tendency of any parts being lodged between the chute and the barrel.
- the openings 39 in the baffles 31 also facilitate the elimination of liquid collection.
- Curtain 60f prevents any parts from bouncing off the chute and out of the barrel.
- the baffles 31 function to elevate the parts and deliver them to the upper end of the chute. Since the upper end of each chute is flared as at 64, the delivery of the parts is facilitated.
- the pivoted portion 65 is in the upper or solid line position shown in FIG. 8, to guide the parts -to the next barrel. Slots 66 permit liquid to drain through the slots to the secondary scoop 66a back into the tank so that liquid is not carried over. The coating of theunderside of the chute sections minimizes the noise incident to transfer of the parts between tank assemblies.
- anode holders provide anodes in close conformity to the barrel and, in turn, the parts and facilitates the replacement of the anodes.
- the novel drive mechanism assures proper drive without exposing the motor to the liquid contents of the tank.
- a relay 114 operates drive motor 42 of conveyor 11 until contacts 116 are opened by level sensing element 41 to indicate that hopper 12 is full. Next, contacts 120 of sensing element 41 close to thereby latch a relay 121. The actuation of relay 121 closes contacts 122 so that power is supplied through normally closed contacts 124 to start a forward master timer 126.
- Forward master timer 126 opens and closes a plurality of contacts 128, 130, 132, 134 and 136 in timed relationship. Normally open contacts 128 and 130 close immediately upon initiation of timer 126. Normally closed contacts 132 and 136 open, and normally open contacts 134 close when timer 126 completes its timing cycle. After timer 126 times out, it cannot be recycled until it is reset by removing the supply current to it.
- contacts 128 actuates a timing relay 138 which in turn operates a solenoid valve 140 through contacts 141 for a time interval sufficient to discharge the first batch of articles from hopper 12 into barrel 46 of tank assembly 13 by means of the arrangement previously described.
- the closure of contacts 130 picks up a relay 142 which starts motor 52 of the first barrel (the first motor) in the forward direction.
- the first barrel continues to run forward until the opening of contacts 136 terminates the forward cycle of timer 126.
- contacts 132 open to turn off the first motor, and contacts 134 close to start a dwell timer 144 and to energize a relay 150.
- Relay 150 resets timer 174 of the second barrel through contacts 149.
- contacts 146 and 148 operate to respectively release relay 150 and to start a reverse master timer 151.
- Reverse master timer 151 is similar to forward master timer 126 in that it controls a plurality of timed contacts 152, 154, 156, 158, and 160. Normally open contacts 152, 154 close immediately upon the initiation of timer 151. Normally closed contacts 156 and 158 open and normally open contacts 160 close when timer 151 times out.
- relays 162 and 164 The closures of contacts 152 and 154 energize relays 162 and 164.
- Relay 162 starts the first barrel in reverse while relay 164 resets forward master timer 126 by means of contacts 124. (The feed to timer 151' is maintained through contacts 152 with contacts 166 being provided to prevent feedback to contacts 134 and timer 144.)
- the first barrel continues in reverse until the opening of contacts 156 terminates the reverse cycle of timer 151.
- the concurrent opening of contacts 158 turns-off the first motor, and closure of contacts starts a dwell timer 168 which by opening contacts 170 after the dwell, resets timer 151 and starts the next forward cycle of the first barrel by releasing relay 164 to close contacts 124.
- relay 162 also closes contacts 172 to thereby both initiate timer 174 and start motor 52 of the second barrel (the second motor) in the forward direction so that the second barrel can receive the articles being discharged from the reverse-running first barrel.
- Timer 174 controls a'plurality of timed contacts 176, 178, and 182, while the forward rotation of the second motor is controlled by a relay 184.
- Contacts 176 close concurrently with the start of timer 174 while contacts 178, 180, and 182 are actuated when timer 174 times out.
- Contacts 176 maintain power to timer 174 after contacts 172 drop out, and the second barrel continues to run forward until the opening of contacts 178 terminates the cycle of timer 174. Simultaneous with the cycle termination, contacts 180 open to turn off the second motor, and contacts 182 close to pick up a dwell timer 186. After the dwell of timer 186, which affords the second motor sufficient time to come to rest, contacts 188 close to pick up relay 190 which runs the second motor in reverse so that it can discharge its articles. The second barrel continues in reverse until the first barrel completes its next forward cycle. Relay 194 controls contacts (not shown) which are interlocked with the control circuitry of the third barrel.
- control circuitry for operating the first two barrels of the plating apparatus.
- the forward and reverse master timers establish the operating cycle of the first barrel with each of the succeeding barrels in the apparatus being slaved to its preceding barrel.
- the portion of FIG. 17 below line AA is duplicated for each barrel subsequent to the second barrel, with the electrical interlocks being arranged in similar fashion with the immediately proceeding and succeeding barrels.
