AUTOMATIC SOB'I'IER FOR JEULNGH PRESSES,

Application filed November 1, 1924.

This invention relates to a sorting device for punch presses for automaticallyseparating the stampings from the scrap discharged from the press and deliver them to separate collection receptacles during the operation of the press.

One object of my invention is to make the sorter a single and inexpensive fixturev Fig. 1 is a side view of a punch press equipped with a sorter of my invention;

Fig. 2 is a front view of the press so equipped p Fig. ,3 is an enlarged top view of the sorter removed from the press;

Fig. 4 is a side view of the same;

Figs. 5 and 6 are vertical sectional iews on lines 54-5 and 64-6, respectively, of Fig. 3;

Fig. 7 is a perspective view of ,a flanged ing; a

8 is a like view of the scrap center he eoi- The punch press shown in Figs. 41 and 2 is of the open back, inclinable type. It has a supporting base 1 and an upper part 2 on which are mounted the operative parts of the press, including a sliding ram or cross-head 3 connected by a rod 4 with the operating shaft ,5, on which is a combined fly-wheel and driving pulley 6. The crosshead 4 carries a punch 7 coacting with a die 8 at the table of the machine, as usual in structures of this character.

The sorter of my invention comprises two sheet ,metal gutters .or troughs 9 and 10, one above the other and combined to form a single unit or fixture. In the form shown in the drawings, the lower trough alias a fiat bottom wall 11 andupright ,side walls 12 12. Said trough 9 is provided with an outlet chute 13 at its trout or outerend Serial No. 747,309.

and at one side of the same. The flat bottom wall of the chute 13 is a continuation of the bottom wall 11 of the trough while the

side walls

14, 15 of the chute join the

respective side walls

12, 12 of the trough and are at an angle or inclination thereto with the front wall 14 of the chute extending across the outer end of the trough, as shown in Fig. ,3.

The upper trough 10 is arranged above the bottomv wall 11 of the lower trough 9 and,

being in Zigzag form, extends back and forth across the trough 9 from one side wall 12 thereof to the other, as shown in said Fig. The upper trough 10 has a flat. bottom wall 16 and upright side walls 17, 18, the latter being in contact with the

side walls

12, 12 Where the trough 9 meets the same. ,At these places of contact, the walls are secured together for supporting the trough 10 in the other one and abov its bottom wall 11, as described.

The outer end of the upper trough 10 is at the side of the device opposite the chute l3 and extends through the front wall 14 of the lower trough, as shown, to provide an outlet chute 19 for said: upper trough.

The portion 20 of the side wall 18 at the inner end of the trough 10 extends at an inclination inward to makethe inlet end of said trough hopper-shape, as shown in Fig. 3. i

The angular portions a, a of the side walls 17, 18v extend across the trough 9 and are provided with elongated, relatively narrow slots 21, there being one slot in ,each angular portion and extending substantially the full length thereof. These

slots

21,21 extend above the bottom wall 16 and have their lower edges flush therewith for opening the upper trough {to thelower one.

Extending above the troughs 9, 10 .are up

rights

22, 22 secured to the

side walls

12, 12

ot the lower trough 9 adjacent its rear end, as shown in Figs. 3 to 5. A cross-bar 23 extends between the ,upper ,ends of these uprights and the upwardly bent ends of said bar are pivoted to the uprights 22 ;by horizontal pins or

trunnions

24, 24. A rod 25 extends across said bar 23 from the rear end of thedevice, and is secured to saidhar by a loop-shaped strap 26.' A rubber loll-1nper 27 is carried ;by the rod 25 at its forward enchand strikes against a bridge piece .011,

in position with'its troughs 9 and 10 opening upward and with the inner end of the bumper rod below a lug or projection 29 (Fig. 1) on the rear side of the cross-head orram 3 at the punch 7. The

chutes

13 and 19 at the outer end of the sorter are over their respective collection receptacles 30, 31, as shown in Fig. 2.

In stamping out sheet metal rings with turned up flanges, such as are used as gromets for holding together the sheet metal and asbestos layers of cylinder head gaskets, the flat metal parts out from the center of the rings are in the form of discs and are treated as scrap from the operation. Heretoi ore the rings andcenters were discharged from the press into one collection receptacle,

thus mixing the rings with the scrap and, both being relatively small and or thin gauge, made separation a troublesome and expensive job, especially as the parts tend to adhere by reason of oil being on them.

The sorter of my invention separates these parts and deposits them into separate receptacles. The rings are indicated by 32 in Fig.

i 7, and the scrap centers by 33 in Fig. 8.

These discs in the punching operation are fed up through a bore 3& (Fig. l) in the punch and are discharged therefrom at its upper end through an outlet slot 35. This slot discharges the discs into the inner or entrance end of the upper trough 10. The rings 32 come 01E the die 8 and also drop into the trough 1O inasmuch as its bottom wall 16 extends clear across the lower trough 9 at such end.

' As the punch 7 is reciprocated, its lug 29 in moving against and away from the inner end of the rod 25 causes thebumper or vibrator 27 to give intermittent blows or taps on the sorter and jar the same continually during the operation of the press to cause the rings and centers to slide down the trough 10. The centers 33 slide fiatwise down the trough 10 and on reaching the slots 21 pass through and drop into the lower trough 9, from which they are discharged into the receptacle 30, thus being separated from the rings 32 which are too wide for the slots 21 and remain in the upper trough 10 to be discharged therefrom into the receptacle 31. Each angular portion a of the trough 10 has its slot 21, so that in case some of the discs pass the upper slots they will in time pass into the lower trough 9 through the lower slots. 'l Vith the trough 10 above the bottom wall 11 or the trough 9, the former does not interfere with the discs sliding down the trough 9 from any slot 21.

This sorter may be equally as well used for other stampings having flanged rings and fiat centers, such as produced in making sheet metal rings for combined sheet metal and asbestos gaskets. I do not wish to have my invention limited either to the particular product described or to the details of structureshown and described, as the latter may be variously changed and modified without departing from the spirit and scope of my invention.

I claim as my invention i 1. A sorter adapted to be applied to a punch press and having two downwardly inclined troughs with outlets at their outer ends, said troughs being connected and arranged one above the other with the upper trough disposed to initially receive both the stampings and the. scrap as discharged from the press, said upper trough having slots therein for the passage only of the scrap from the upper to the lower trough, and means carried by the sorter for jarring the same for progressing the scrap and stampings down the troughs and disposed to be actuated by a moving part of the press.

2. A sorter adapted to be applied to a punch press and having two downwardly inclined troughs with outlets at their outer ends, said troughs being connected and arranged one above the other with the upper trough disposed to initially receive both the stampings and the scrap as discharged from the press, said upper trough extending zigzag across the lower trough and having slots in its angular portions for the passage only of the scrap from the upper to the lower trough, and means carried by the sorter for jarring the same for progressing the scrap and stampings down the troughs and disposed to be actuated by the ram of the press.

3. A sorter adapted to be applied toa punch press and having two downwardly inclined troughs with outlets at their outer ends, said troughs being connected and arranged one above the other with the upper trough disposed to initially receive both the stampings and the scrap as discharged from the press, said upper trough having slots therein for the passage only of the scrap from the upper to the lower trough, an anvil carried by the upper trough, and a bumper carried by the sorter above the upper trough and disposed to be actuated by the ram of the press to deliver blows against said anvil to jar the sorter in the operation of the press.

4. A sorter adapted to be applied to a punch press and having two downwardly inclined troughs with outlet spouts at their to deliver blows against a part of the upper trough to the sorter in the actuation of the opposite end of the rod by the ram of the press.

5. A sorter adapted to be applied to a punch press and having two downwardly inclined troughs with outlet spouts at their outer ends, said troughs being arranged one above the other with the upper trough disposed to initially receive both the stampings and the scrap as discharged from the press, said upper trough having slots therein for the passage only of the scrap from the upper to the lower trough, upright members fixed to the sorter on opposite sides thereof and extending above the upper trough, a cross-bar extending between said members atthelr upper ends and pivoted thereto, a rod exthe opposite end of the rod by the ram of the press.

6. A sorter adapted to be applied to a punch press and having two troughs with flat bottom and upright side walls, said troughs having diverging outlet spouts at their outer ends and arranged one within the other with their side walls secured together and their bottom walls vertically spaced apart, the upper trough being Zigzag and extending across the lower trough trom one side wall thereof to the other with elongated slots in the lowermost portions of the upright side walls of said upper trough and flush with the bottom wall thereof, and a member carried by the sorter and disposed to be actuated by the ram of the press for delivering blows to the sorter for jarring the same in the operation of the press.

In testimony that I claim the foregoing as my invention, I affix my signature this 22nd day of October, 1924.
