The method of the present invention relates to the removal of electroprecipitated plates from cathodes having a suspension bar for vertical support of a cathode on the periphery of a carousel apparatus mounted for 360 ° rotation past a plurality of positions located around the perimeter of the carousel. from the steps of periodically feeding said cathodes from the loading station to the carousel, rotating the carousel to move the cathode from the loading station to the hammering station to detach the top edges of the electrodeposited plates 20 from the cathode; and rotating the carousel to transfer the peeled cathodes to a unloading station where said peeled cathodes are moved away.

The top edges of the electroprecipitated plates are removed at the hammering station by attaching the top of the cathode and hitting the electrodeposited plates on top of the roof 30 at random near their top edges on opposite sides of the cathode.

Openings are formed between the top edges of the electroprecipitated plates and the cathode 35 at the opening position by bending the center portion of the cathode laterally in the first direction to form an opening between the top edge of the electroprecipitated plate and the cathode and pushing at least one I SH! H ti i I l ii 941 53 3 a rod into said opening, and bending the cathode laterally in the opposite direction to form an opening between the top edge of the second electrodeposited plate and the cathode and inserting at least one rod into said aperture, and pulling said fingers from the cathode to remove the electrodeposited plates from the cathode. If at this point the separation of the plates from the cathode has not been completed, it can be completed at the second total opening station by feeding each partially detached plate between the release pins 10 which adhere to the top edges of the plate and completely remove the plates from the cathode. In addition, complete removal of the thin plates can be ensured by using a separation station after the opening or full opening position, whereby the upper end of the cathode is attached and a pair of opposing release knives are inserted between the plates and the cathode, thus completing the removal. However, it was found that in most cases a total opening station and an additional separation station are not necessary because the entire removal operation can be performed at the opening station.

A passive guide extending to the next station can be placed between the electrodeposited plates and the cathode to prevent the plates from settling on the cathode 25 to rest when the plates are only partially removed, and * a second passive controller extending to the next station is placed outside the electrodeposited plate to prevent said plates from moving excessively in the lateral direction when the plates are completely detached from the ka-30 proof.

The device of the invention for removing electrodeposited plates from cathodes consists, in combination, of a carousel arranged to rotate about 360 °, having means for supporting and periodically advancing the cathodes to a plurality of positions located on the circumference of the carousel. The stations usually consist of a loading station receiving cathode plates with electrodeposited plates 4 94155 coated, a hammering station for removing the upper edges of said metal plates from the cathode, an opening station for gripping outlets of said metal plates and forming an opening for the upper edges of said metal plates needles into said openings and removing the metal plates from the cathodes by pulling said fingers out, from the removal station where the pairs of metal plates are removed, and from the unloading station where the cathodes 10 from which the plates have been removed are unloaded.

The carousel has a plurality of sides and the members of the carousel supporting the cathodes each consist of a pair of downwardly extending side supports spaced apart so that the cathode fits between them on each side of the carousel, a suspension bracket attached to each side support near its top, supporting a cathode flagpole, a V-support having a tip attached at opposite ends 20 to the lower ends of the side support pairs below the lower end of the cathode, and means for opening the V-support. Each suspension bracket is L-shaped and has a small recess located in the horizontal lower portion of the L in which the cathode suspension rod is located.

25

Each V-support consists of a pair of spaced, parallel bars rotatably mounted at the lower ends of the side support pair and a pair of opposing plates, one of which is attached to one of said bars to form a V-shape in a closed position therebetween, and means for: rotating said rods and: · plates attached thereto to separate said plates into the open position.

35 The hammering station consists of a pair of opposite, reciprocally mounted carriages, each with a plurality of pneumatic hammers, one on each side of the cathode, and the carriages can be pushed towards or withdrawn from the cathode, the pneumatic hammers randomly hitting electrically deposited plates. in the vicinity of the upper edges of the plates in order to release said upper edges. The trolley has upper support members that firmly contact the roof-5 slide above the electrodeposited plates and lower support members that firmly adhere to the electrodeposited plates below the pneumatic hammers.

The opening station consists of a pair of opposite, reciprocally mounted carriages on each side of the cathode, each having an upper press for pressing the cathode above the top edge of the electroprecipitated plate and a lower pusher for pressing the electrodeposited plate near its lower edge. the cylinder assembly is operatively connected to it for independent operation and at least one downwardly directed rod is pivotally mounted on the carriage so that the cathode can be pressed tightly between the upper presses and the electrodeposited plates in the vicinity of the lower edges 20 which are pressed down by the lower presses. towards. The cathode is bent in the first direction by extending a first push rod to form an opening between the top edge of the electrodeposited plate and the cathode on the opposite side of the cathode, and inserting at least one pin into said opening, and then bending in the opposite direction by pulling out the first push rod and extending the second rod forming an opening between the upper edge of the electrodeposited plate and the cathode on the opposite side 30 of the cathode, and inserting at least one pin into said opening. The second push rod and carriages are withdrawn so that the rods inserted between the electrodeposited plates and the cathode detach at least partially and generally completely the electrodeposited plates from the cathode.

An elongate arcuate passive guide may be mounted extending from the opening station to the next station between the top edges of the electrodeposited plates and the cathode to prevent said top edges from settling back to rest against the cathode if they are only partially removed. An elongate arcuate passive guide is also arranged to extend between the opening station and the next station 5 in order to support electrodeposited plates in the event that the plates become completely detached from the cathodes, as is often the case.

The alternative total opening station consists of a pair of opposed, reciprocally mounted carriages on all sides of the cathode, each with a pair of downwardly suspended, spaced apart pins for receiving and securing between them a partially detached top edge of an electrodeposited plate, and means for pulling out said carriages. there are hanging rods for removing electrodeposited plates from the cathode if they have not been completely detached at the opening station.

The separation station may also be located between the total opening station and the off-20 room station to ensure that the electrodeposited metal plates have detached from the cathodes prior to their removal. The separation station consists of means for attaching the upper end of the cathode and a pair of opposing separation knives, one on each side of the cathode, for removing the electrodeposited plates from the cathode to the end by lowering the knives' ·; between the electrodeposited plates and the cathode. Such a position is necessary only in a few cases and is usually not necessary.

An ejection station is a bottom ejection station having a housing that receives orthogonal pairs of sheet metal and turns said orthogonal pairs of sheet metal to a horizontal position and removes said orthogonal pairs of sheet metal horizontally from a carousel.

In more detail, the discharge station consists of a housing located below the cathode and receiving the disconnected

A cathode load having electrodeposited metal plates that have been washed is loaded onto a transport carriage 30 mounted to run reciprocally along the upper rails 32 of the transport frame to transport the bundle ag-5 toward the assembly 34 which turns and lowers the bundle. The cathode bundle, which generally includes 44 cathodes, is rotated about 30 ° by a pivot and lowering assembly 34 toward a chain conveyor, designated 36. The finished cathode bundle is placed on a chain conveyor 36 which carries the bundle toward the loading station 14. The overhead lever 38 raises one cathode and transfers it to a fixed beam, repeating this movement until the cathode is transferred to the carousel suspension bar 14 at the loading station 14 for intermittent advancement through each station 15 and subsequent removal at removal station 24, where detached plates are removed. cathodes from which the plates have been removed.

Carousel Assembly 20 Referring specifically to Figures 2-6, the carousel 10 includes a support frame 50 having sturdy steel corner supports 52, diagonal corner supports 54 that serve as reinforcements bolted or welded to horizontal beams 56, and longitudinal beams 58. Rectangular beams 25 transverse , best seen in Figures 3 and 4, support the drive mechanism assembly 62. The vertical central shaft 70 is mounted at its lower end on a base 72 having a bearing (not shown) for rotation and is supported at its upper end by a bearing 74 mounted in the housing 76 supported by transverse beams 60.

• ·

The radial beams 78, which are attached at their inner ends to a collar 80, which itself is attached to a post 82 forming part of the shaft 70, are supported by diagonal biases 84 extending between the base of the collar 80 and the center of the radial beams 78. The circumferential beams 86 connect the outer ends of the beams 78 to form one side of a plurality of sides of the carousel 941 53 10 and support the same number of cathode hangers 88, three of which are shown in Figure 2.

Each cathode hanger 88, the details of which are shown in Figure 7, consists of downwardly extending side arms 90 rigidly connected to beams 86 by plates 92 welded thereto. The L-shaped suspension bracket 94 welded to the inside of each arm 90 is intended to receive a suspension rod 96 attached to the upper edge of the cathode 98, shown in broken lines. Cathode 98 and its structure are detailed in Applicant's U.S. Patent 4,882,027.

A pair of spaced apart rods 100 are mounted for rotation 15 in sleeves 102 rigidly attached to the lower ends of the arms 90 to support a V-beam 104. Each V-beam 104 consists of a pair of opposed top plates 106 rigidly connected to their respective transverse rods 100 by spaced-apart plates 108; the reason for this is explained 20 below.

It can be seen that the bottom edges at the boundary of the cathode 98 and the metal plates 112, 114 are placed slightly above the V-support 104.

25

The carousel 10 is rotated clockwise, as seen in Figures 5 and 6, by a Geneva-type indexing drive assembly 62 consisting of a hydraulic motor 120 driving a torque arm transmission 122 having a pair of downwardly extending rotating intermediate shafts 124 via a clockwise rotating shaft 132. 126, which · engage in radial grooves 128 formed

To the Geneva transmission wheel 130, which is best shown by the dashed lines in Figure 5. The Geneva gear 130 has two 35 radial grooves 128 spaced 30 ° apart, one groove for each of the twelve drive position grooves, to allow accurate indexing in the carousel when the cathode hanger is introduced for each position. At the same time as both rollers 124, 126 are in contact with successive grooves, the wheel 130 and, as a result, the entire carousel assembly are stationary. At these junctions, the cathode hangers are positioned correctly at the station and the drive motor 120 is stopped for a predetermined time so that the desired operations can take place at all the different stations.

Loading Station 10 Cathodes 98 having metal plates 112, 114 are periodically transferred to cathode hanger assembly 88 on loading station 14. The suspension bar 96 is supported on both ends by hangers 94 and the bottom edges 110 are located above the V-supports 104. The transfer of cathode 98 to the suspension supports is preferably performed in about 2.5 seconds, which time is part of the minimum period time at each station, which is about 4.5 seconds, leaving about 2.0 seconds for cathode transfer to and from the cathode hanger. at the next station. The cathode 98 is then transferred to the hammering station 16 by rotating the drive assembly 62, where the upper edges of the electrodeposited plates are removed from the cathode by the hammering station.

Hammering Station 25 In Figures 8 and 9, the hammering station 16 consists of a pair of opposed reciprocally mounted carriages 150, 152 mounted on a frame 153 moving toward and away from the cathode 98 so that opposite compressed air hammers 154, 156 are supported by the frame when they are in operation, striking the metal plates 112, 114 located at the cathode 98 near the top edges 158, 160 of the plates.

«·. An opposing pair of presses 162, 163 mounted on vertical support members 166, 167 carried by carriages 150, 152 presses the upper end of the cathode 98 during hammering-35 operation, while the lower opposite pair of presses 164, 165 engages the lower portions of the plates 166, 167 and secure that the metal plates do not detach from the cathode prematurely. In the preferred mode of operation, the striking surfaces of the hammers are steel and the hammers are moved by an ordinary air cylinder so that their striking pattern is random.

5 Opening station

The hammering operation usually detaches the top edges 158, 160 of the metal sheets from the cathode 98, whereby bending the cathode as shown in Figures 10-12 releases one top edge 160 and then the other top 10 edge 158 from the cathode 98. Referring specifically to Figure 10, the opening station 18 consists of a pair opposite carriages 168, 169, each mounted for reciprocal movement toward and away from each other, which movement occurs along the guide frame 170 by a piston-cylinder-15 blade assembly 171 mounted on the frame 173. The right portion of the figure shows an upper clamp 172 covered with polyurethane designed to rigidly adhere to the top of the cathode 98 above the top edges 158, 160 of the metal sheets and metal bottom presses 174 which compress the extreme bottom of the cathode 98 and the metal sheets 112, 114 just above the V-support 104.

The piston-cylinder assembly 176, carried by carriage 168, unit 164, allows the central push rod 180 to move to the initial position depicted in Figure 10 and Figure 11 by broken lines, bending the cathode and separating the detached top edge 160 from the cathode 98. from the cathode 98 enough to insert the rod 182 from the opposite side of the rod 180 into said opening using the piston-cylinder 184.

The piston-cylinder assembly 176 is then withdrawn 1 and the operation is repeated on the opposite side 1a of the cathode 98 using an opposite piston-cylinder assembly, not shown, by bending the cathode 98 in the opposite direction 35 to separate the detached top edge 158 from the cathode 98 to provide an opening. 183 is pushed in the same manner as shown in Figure 12.

13 94153

When the operation of inserting the rods 182, 183 into the openings between the upper edges 158, 160 and the cathode 98 is completed, the rods 182, 183 are pulled out with the carriages 168, 169 sequentially or simultaneously to at least partially and generally completely remove the metal plates from the cathode, so that the upper edges 158, 160 are bent outwardly from the arcuate passive guides 192 which extend to the next position and engage and prevent said upper edges 158, 160 from returning to rest against the cathode 98 as the carousel is rotated and indexed to the next position. The arcuate, passive guides 190, one of which is shown, extend to the next station on each side of the cathode 98 to support the metal plates, as shown in Figure 10 by dashed lines 15, in case the plate is completely detached from the cathode, as is usually the case.

Alternative total opening station

Referring to Figures 13 and 14, in the case of only partial detachment 20, a cathode with partially opened metal plates is next placed in position 20, where a pair of opposite, reciprocating carriages mounted on opposite sides of the cathode are generally at rest in the detachment pins 200, 202, where they can receive metal plates coming from the opening station between them. The rods 200, 202 of each pair are spaced apart from carriages 204 mounted on both sides of the frame 206 to peel the metal plates from the cathode when said rods 200, 202 are retracted. When the carriage 204 is fully retracted, as shown by the broken lines in Figure 14, the inner pin 202 is pulled out enough to allow the metal plates 112, 114 to fall onto the passive guide rails 210 extending in an arc to the discharge station. The lower ends of the metal plates 112, 35 114 are usually detached from the cathode 98 and fall into the V-support 104, the angle between the plates 106 being approximately the same as the angle assumed between the fully opened plates.

i 94153 14

Alternative separation station

The separation station 22, which can be located downstream of the total opening station 20, can be used to remove relatively flexible electrodeposited sheets, such as thin copper sheets or zinc sheets, which do not have the same rigidity as normal thickness copper sheets. The separation mechanism at station 22 consists of a frame 191 and carriages 193, 194 superimposed thereon to extend and withdraw from the cathode 98 using piston-10 cylinder assemblies 195, one of which is shown, so that the upper end of the partially detached cathode 98 can be firmly gripped. with opposite presses 196, 198. Polyethylene coated knives 198 supported by a piston-cylinder assembly 199, one of which is shown, are then lowered simultaneously between the electrodeposited plates and the cathode to complete the removal of said plates to the bottom of the cathode. This is shown in Figure 18.

20 Discharge station

The cathodes 98 from which the metal plates 112, 114 have been removed and supported by the V-support 104 are indexed to the removal station 24, shown in more detail in Figure 15, for removal from the horizontal removal apparatus. The station 24 consists of a pair of 25 opposing hydraulic buffers 220 mounted on support frames 222 for ejection and retraction, each of which operates on a piston 224 extending from the cylinder 226. The detached metal plates 112, 114 are pushed from a separate position shown in Figures 15 and 30 by dashed lines 16. loosely against the cathode 98 for vertical alignment followed by opening of the V-support 104, as illustrated by the broken lines in Figure 16, by rotating the tan arms 100 and rotating the plates 106 around the hinge with actuators (not shown) located at station 24. Metal plates 112, 114 fall by gravity vertically to the position depicted in Figures 112a, 114a in Figure 15, guided by opposing rollers 230 which are secured to the ends of the buffers 220 by pins.

94153 15

The lower support assembly or sheath 232 is rotated 90 ° clockwise as shown in Figure 15, to a position illustrated by dashed lines 232a, and a pair of opposed metal plates are pushed out by a hydraulic buffer 234 to the gun-5 indicated by 112b, 114b for removal to the feed belt.

The cathode from which the plates have been removed can then be indexed through the inspection station 25 to the rejection and replacement station 26, 10 where the damaged cathodes are replaced.

The carousel is then indexed to a cathode unloading station 28 for intermittent cathode loading and unloading on a chain conveyor to collect a full load of cathodes that are removed from the detachment assembly and transported to an electrolysis hall for reuse.

Bundling station 20 The detached metal plates pass in pairs from the discharge station 24 by means of a shuttle conveyor onto a 100 ton corrugating press 250. Every other pair of metal plates is corrugated and alternating pairs of corrugated and non-corrugated plates are transferred onto trigger rollers which place the plates on top of the stack-25 amish elevator 252 at a cycle speed of about 4.5 seconds ’· per double plate.

The stacking elevator 252 consists of a lowering assembly that lowers the stack as it is formed so that the distance between the release rollers and the top of the stack remains constant. Once the required number of pairs of sheet metal, i.e., smooth plates 112, 114, and corrugated plates 112a, 114a, as shown in Figure 17, have been assembled to form a bundle weighing, for example, about 3 tons, the bundle 35 is lowered onto a chain conveyor 254. is applied to the weight crane 256 and the binding crane 258. The lowering assembly is returned to its highest position so that it can receive 16 94153 pairs of sheet metal for the next bundle.

After weighing the bundle, with conventional weighing equipment 5a at crane 256, the bundle is usually placed on a pair of wooden logs, not shown, where the bundle is compressed prior to packaging and the steel straps 115 are clamped around the bundle.

The present invention provides many important advantages.

From cathodes, such as stainless steel cathodes on which copper plates are electrodeposited, the plates can be released quickly and accurately without damage to the cathodes or plates, allowing efficient and reliable operation. Operational automation minimizes or eliminates manual operations, increasing production speed and avoiding many hazards. The shape of the carousel minimizes space requirements, saving construction costs.

The finished bundles of sheet metal, stacked and bonded in alternating layers of corrugated and non-corrugated or smooth sheet, consist of continuous elongate air ducts extending from end to end of the bundle, which ducts increase heat transfer in a future smelting operation. Such a bundle is a new product.

It is, of course, to be understood that modifications may be made to the embodiment of the invention described herein without departing from the spirit and scope of the invention as set forth in the appended claims.
