nite This invention relates to an article working apparatus, and more particularly to selectively operable article working apparatus.

An object of the present invention is to provide an improved apparatus for working selected portions of articles.

Another object of the invention is the provision in an apparatus having a plurality of tools, of mechanism for selectively positioning an article relative to the tools and for selectively actuating the tools.

With these and other objects in view, the invention contemplates the provision of a plurality of punch and die sets of different configurations arranged in a row in a punch press. The dies are mounted on a stationary plate that also supports a carriage to which an elongated article to be perforated is clamped for movement therewith in a first direction through the punch and dies. The punches are mounted for reciprocation with the ram of the press and are urged upwardly against cam plates which are reciprocable individually selectively by actuating means including control switches to shift the punches from normally inoperative positions'on the ram to operative positions for rendering the punches effective to perforate thearticle when the press is actuated. The control switches are mounted on the carriage in a row disposed transversely of said first direction.

A slide is mounted on the carriage for movement in a second direction above and parallel tothe switches and has a hollow handle by means of which the carriage and the slide may be actuated in said first direction and the slide actuated in the second direction. A feeler is mounted for. vertical movement in the handle and is urged upwardly to a normal position above a gage plate which is remov ably mounted on the stationary plate and provided with a plurality of apertures for receiving the end of the feeler in response to manual depression thereof. The apertures are disposed in the gage plate in a predetermined coded arrangement in spaced relation to each other in the first and the second directions. A switch actuating member mounted on the feeler above the row of switches actuates the switches individually in response to vertical actuation of the feeler.

With an article clamped to the carriage, an operator may engage the handle of the carriage and move it in the first and the second directions to align the feeler with successive apertures in the gage plate and the switch actuating member with selected control switches and then successively depress the feeler, thereby effecting the movement of the article to selected positions relative to the punch and dies and the selective actuation of the punches.

Other objects and advantages of the invention Will become apparent by reference to the following detailed description thereof and the accompanying drawings illustrating a preferred embodiment of the invention, wherein:

Referring to the drawings, the present apparatus in-- cludes a punch and die set having a punch holding plate 15 (FIG. 1) and a die holding plate 16 with a row of perforating punch and die units .17 therebetween for punching apertures 18 (FIG. 3) of predetermined different configurations into articles in the form of flat plates 19 onto which electrical components are to be mounted. The punch and die set is mounted in a press 20 with the die holding plate 16 secured to the bed 21 of the press and with the punch holding plate 15 secured to the ram 22 of the press for reciprocation therewith. The ram 22 is reciprocated through successive cycles by conventional drive means under control of a press starting solenoid 23 (FIG. 9). Aligned horizontal apertures 26 in the dies 27 of the punch and die units 17 form a horizontal passageway for guiding the mounting plate 19 therethrough into the path of the punches 28 of the punchand die units 17. The dies 27 have bases 29 thereon which are secured to the plate 16 at their forward end by screws 30 and at their other end by quick acting clamping members 31 to permit ready replacement of the punch and die units.

Each of the clamping members 31 is secured at one end by a screw 32 to a mounting block 33 fixed to the 1 plate 16 and has an upwardly directed vertical slot 35 cut therein to provide for the flexing of the free end thereof. A horizontal slot 36 is also formed in one end portion to provide a pair of parallel fingers capable of flexing slightly relative to each other. A round rod 40 having a flat surface engageable with the clamping-members 31 is oscillatably supported in bearing blocks 41 and is provided with a handle 43 by means of which the rod may be rotated to actuate the clamping members 31 and efiect the clamping of the other ends of the bases 29 of the dies against the plate 16.

The punches 28 of the perforating units 17 (FIGS. 4 and 5) have T-heads 46 removably supported in T-slots 47 in holder members 48 which are mounted for vertical movement in guideways 49 in a member 50 secured to the punch supporting plate 15. The holder members 48 are guided for vertical movement by headed guide rods 51 secured thereto slidable in the plate 15, and the holder members 48 are stressed upwardly by springs 52. Cam surfaces 54 formed on the upper portions of the holder members 48 cooperate with cam surfaces 55 on cam bars 56 which are slidably mounted for horizontal movement in the guideways 49 in the member 50. The cam bars 56 are connected to and reciprocated by pistons 57 of airoperated actuators 58 secured to a plate' 59 fixed to the punch supporting plate 15.

Compressed air is admitted to one end of each of the actuators 58 individually from a supply line 62 through valves 63 to advance the cam bar 56 to effect the shifting of the punch 28 to its lower operative position (FIG. 4) and render it effective to perforate the mounting plate 19 when the press is actuated. Each of the valves 63 is shifted to one position by the energization of a solenoid 65 to effect the forward movement of the cam bar 56', and the valve 63 is shifted to another position in response to energization of a solenoid 67 to effect thereturn movement of the cam bar 56. The solenoids 65 are connected individually to a source of current 70 (FIG. 9) in series Patented Aug. 7, 1962.

with normally open switches 71 for selective energization of the solenoids. If desired an auxiliary pulse generating unit 75 may be connected in series with each of the solenoids 65'to supply a pulse for momentarily energizing the solenoid. 65.

Normally open switches 77 mounted on the punch holding plate in the path of movement of the cam bars 56 are connected to the source of current 70 in series with thepress. starting solenoid 23 and serve to complete a circuit and effect theenergization of the solenoid 23 and the actuation of the press in response to forward movement of a cam bar 56. The valve actuating return solenoids 67. are connected to the source of current 70 in parallel with each other and in series with a normally open switch 73 which is mounted on the press and actuated to closed position at the end of the return stroke of the ram 22 to effect the energization of the solenoids 67 and the return movement of all of the cam bars 56 subsequent to the punching of an aperture in the mounting plate 19.

The switches 71 are mounted in a row on a carriage 80' (FIGS. 7 and 8), which carriage is provided to support and move the article. 19 into the horizontal guideway 26 of the dies 27 and to locate the article is selected positions relative thereto. The carriage 80 is in the form of a rectangular block mounted for sliding movement in a guideway 81 formed by a pair of L-shaped guide members 82. The guide members 82 are secured to a plate 83 which is fixedly attached to the die supporting plate 16 with the guide members 82 extending laterally from and in substantial alignment with the dies 27.

The article 19 to be perforated is placed in the guideway 81 and supported on the ledges 84 of the guide members 82 in alignment with the horizontal passageway 26 in the dies 27; One. end of the article 19 is positioned against a vertical surface 85 on the carriage 80 (FIG. 7) and below an overhanging portion 86 which forms a fixed jaw against which the end of the mounting plate is clamped by a movable jaw 87 on the carriage 80. The jaw is piv-- otally supported at one end thereof on a pin 88 and is connected intermediate its ends to one end of a link 89, the other end of which is connected to a handle 90 movable between two predetermined positions to effect the clamping and release of the article 19 relative to the carriage 80. A plurality of pins 91 having pointed ends projecting from the jaws 86 and 87 may be provided for gripping the article 19.

A slide 95 is mounted on the carriage 80 in a slideway 96 for movement above and parallel to the row of switches 71 and transversely of the longitudinal movement of the carriage. At one end thereof the slide 95 (FIG. 9) is provided with an upstanding hollow handle 97 by means of which the slide 95 and the carriage 80 may be moved in a first direction to advance the article 19 longitudinally of the row of punches 28 and by means of which the slide 95 may be moved relative to the carriage 80 in a second direction transversely of the first direction. A feeler 98 in the form of a rod is mounted for vertical movement in the handle 97 and is maintained by a spring 99 in a normal upper position with the reduced lower end 100 of the feeler disposed above and adjacent to a gage plate 101. The gage plate 101 is releasably secured to the supporting plate 83 adajcent to the path of movement of the carriage 80 by a pair of clamping members 102 (FIGS. 1 and 2) engageable with the ends of the plate.

An arm 103 (FIG. 8) fixed to the feeler 98 for vertical movement therewith extends horizontally from the feeler over the row of springs 71 and has a downwardly directed switch actuating element 104 on the end thereof for closing the switches 71 individually in response to downward movement of the feeler. As shown in FIG. 8, the lower end 100 of the feeler 98 is normally disposed slightly above the top surface of the gage plate 101 and is prevented thereby from being moved downwardly except when the feeler has been moved horizontally to predetermined positions into alignment with one of a plurality of recesses 106 formed in the gage plate. The recesses 106 are arranged in predetermined locations relative to each other in accordance with a predetermined pattern or code of apertures 18 to be punched in the article 19, to permit the alignment of the portion of an article 19 to be punched, with the selected punch and die, and to position the switch actuating element 104 of the feeler 98 over the switch 71 assocaited with the selected punch and die.

When it is desired to punch perforations 18 into the article 19 in accordance with a selected code determined by the gage plate 101, the article 19 is first placed in the guideway 81 and clamped to the carriage between the jaws 86 and 87. The operator then moves the handle 97 to align the end of the feeler 98 with the first recess 106 in the gage plate 101 to cause the movement of the article 19 to a predetermined position with the portion thereof to be perforated located between a selected punch and die and to cause the switch actuating element 104 of the feeler 98 to be positioned above and in alignment with the switch 71 associated with the selected punch and die.

The operator then depresses the feeler into the recess 106 which movement closes the selected switch 71 to effect the energization of the selected solenoid 65, the reversing of the valve 63 associated with the selected I punch and die, the movement of the piston 57 and the cam bar 56 by the actuator 58 from the normal retracted position to the advanced position, the movement of the punch 28 from its normal upper unoperative position to its lower operative position. The forward movement of the cam bar 56 also closes the switch 77 in its path resulting in the energization of the press starting solenoid 23, the reciprocation of the ram 22 and the punching of an aperture 18 in the article 19. At the end of the return movement of the ram 22 the switch 73 is actuated to effect the energization of the valve actuating solenoid 67 and the reversing of the valve 63, resulting in the retraction of the cam bar 56 and the return of the punch 28 to its normal upper unoperative position.

The operator then moves the handle 97 to align the feeler 98 with the next desired recess 106 in the gage plate 101 and again depresses the feeler 98 to initiate another cycle of operation on completion of which this operation is repeated until all of the desired perforations 18 have been punched in the article 19. The carriage80 is then returned to its starting position and the perforated article 19 is removed therefrom.
