Abstract

A battery casing salvage machine comprising a plurality of discrete stations disposed in operative communication by a conveyor means to sequentially remove the original cover from the enclosed battery case and rebuild the battery case and battery cell partitions. The plurality of discrete stations includes a first station comprising a first cutting means including a saw cutting means to remove at least a portion of the original battery cover and the upper portion of the original battery case, a second station comprising a second cutting means including a bevel cutting means to remove the remaining portion of the original battery cover, and a third station comprising a third cutting means including at least one drill means to undercut the battery cell partitions where the cell connectors are fused together. The battery casing salvage machine further includes an automatic feed means disposed in operative relationship to the first station to continuously feed battery casings thereto.

Claims

1. A battery casing salvage machine comprising a conveyor means mounted on a support frame, a first and second station mounted on said support frame, and an automatic feed means mounted on said support frame, said conveyor means disposed relative to said automatic feed means to receive battery casings therefrom at predetermined intervals, said first station arranged in operative communication with said conveyor means to receive battery casings therefrom at predetermined intervals, said first station comprising a first battery support means, a first cutting means arranged above said first battery support means and a battery movement means movably mounted on said support frame, said battery movement means disposed relative to said conveyor means to engage the battery casing thereon and move the battery casing on said first battery support means through said first cutting means to cut at least a portion of the battery casing from the remainder thereof, said second station arranged in operative communication with said conveyor means to receive battery casings therefrom at predetermined intervals from said first station, said second station comprising a second battery support means and a second cutting means arranged above said second battery support means, said second cutting means including a cutting element movably mounted on said second station to permit movement thereof perpendicular to the axis of said second battery support means, said cutting element disposed to engage battery casings on said second battery support means.

2. The battery casing salvage machine of claim 1 wherein said first battery support means comprises an interrupted roller means arranged on opposite ends of a substantially horizontal support element.

3. The battery casing salvage machine of claim 2 wherein said battery movement means comprises a pair of substantially parallel endless chains mounted on a pair of drive sprockets having a plurality of battery engaging elements extending between said substantially parallel endless chains, said drive sprockets being coupled to a first drive means.

4. The battery casing salvage machine of claim 3 wherein said battery movement means further includes a drive clutch coupled to said pair of drive sprockets, said drive clutch operatively coupled to said first drive means by an endless drive chain.

5. The battery casing salvage machine of claim 3 wherein said battery movement means further includes a pair of idler sprockets and a first and second guide means to operatively support said pair of substantially parallel endless chains.

6. The battery casing salvage machine of claim 3 wherein each said battery engaging element comprises a cross-bar, said cross-bar being disposed angularly relative to said substantially parallel endless chains.

7. The battery casing salvage machine of claim 6 wherein said first station further includes a battery guide means disposed to engage battery casings on said first battery support means to secure the battery casings during cutting.

8. The battery casing salvage machine of claim 1 wherein said first cutting means comprises a substantially horizontal endless band saw coupled to a second drive means.

9. The battery salvage machine of claim 1 wherein said first battery support means is pivotally mounted on said support frame and said first station further includes an adjustment means attached to said first battery support means, said adjustment means movable to control the position of said first battery support means relative to said first cutting means.

10. The battery casing salvage machine of claim 9 wherein said adjustment means comprises an upper yoke attached to said first battery support means and a lower adjustment member extending downwardly therefrom in telescoping relation thereto.

11. The battery casing salvage machine of claim 1 wherein said automatic feed means comprises a stop means movable between a first and second position to selectively release battery casings to said conveyor means, an actuator means movable between a first and second position, said actuator means coupled to said stop means to move said stop means between said first and second position, and a control means having a first and second state coupled between said first station and said actuator means, said control means generating a control signal when in said second state to move said actuator means to said second state to release a battery casing from said automatic feed means to said conveyor means.

12. The battery casing salvage machine of claim 11 wherein said control means comprises a switch means disposed to selectively engage said first station, said switch means having a first and second position, said control means generating said control signal when said switch is in said second position when engaged by said first station.

13. The battery casing salvage machine of claim 12 wherein said actuator means comprises an air cylinder having a piston movably between a first and second position disposed therein said air cylinder being operative coupled to a pressurized air supply source, said switch means being coupled to said pressurized air supply source to move said piston from said first to said second position when said switch means is in said second position to move said stop means to said second position.

14. The battery casing salvage machine of claim 13 wherein said automatic feed means further includes a lock means movable between a first and second position to selectively lock battery casings on said automatic feed means, said actuator means coupled to said lock means to move said lock means between said first and second position, said control means being coupled to said lock means to move said lock means from said first position to said second position when said control means generates said control signal to move said lock means to said second position.

15. The battery casing salvage machine of claim 13 wherein said stop comprises a substantially L-shaped member operatively coupled to said piston.

16. The battery casing salvage machine of claim 1 wherein said cutting element includes a movable head and a cutting disk operatively coupled to a third drive means, said cutting disk disposed to bevel the upper portion of the battery casing on said second battery support means.

17. The battery casing salvage machine of claim 16 wherein said second station further includes a bevel guage and alignment means operatively coupled to said cutting disk to control the cutting plane of said cutting disk relative to the battery casings.

18. The battery casing salvage machine of claim 1 further including a third station mounted on said support frame, said third station arranged in operative communication with said conveyor means to receive battery casings therefrom at predetermined intervals from said second station, said third station comprising a third battery support means and a third cutting means arranged above said third battery support means, said third cutting means comprising at least one drill means operatively coupled to a fourth drive means and a lower stop guage, said drill means disposed to selectively engage the battery casing on said third battery support means, said drill means movable between an upper and lower limit, said lower stop guage disposed to engage said drill means at said lower limit to control the depth of the cut on the battery casings.

19. The battery casing salvage machine of claim 18 wherein said third station further includes an adjustment means including a first and second adjustment element to adjust said third battery support means longitudinally and laterally relative to said third cutting means.
