IANUZZI FIG. 8 BYERNEST JAMES BRYNER United States Patent 3,268,992 CAPPER IFQR RESISTOR BODIES Joseph N. lanuzzi and Ernest James Bryner, Bradford, Pa, assignors to Sigma Engineering Service, Inc., Custer City, Pa., a corporation of Pennsylvania Filed Nov. 3, 1964, Ser. No. 408,535 Claims. (Cl. 29203) This invention relates to assembly machines and, more particularly, to machines for assembling articles of manu facture such as electrical resistors for circuit components having an elongated cylindrical or non-cylindrical body having a cup shaped terminal cap forcedont-o each end.
This machine constitutes an improvement over Patent No. 3,054,167.
It is an object of the invention to provide an improved machine for capping bodies.
Another object of the invention is to provide an improved cap feeding device in combination with a capping machine.
A further object is to provide an improved capping device and unloading device in combination with a capping machine.
With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawings:
FIG. 1 is an isometric view of the machine according to the invention;
FIG. 2 is a cross sectional view taken on line 22 of FIG. 1;
FIG. 3 is a top view of the machine;
FIG. 4 is a partial longitudinal cross sectional view of the machine;
FIG. 5 is an enlarged isometric view of the capping mechanism;
FIG. 6 is an isometric view of the capping and unloading assembly; and
FIGS. 7 and 8 are enlarged partial views of the loading mechanism.
Now with more particular reference to the drawings wherein like index numbers refer to similar parts of the machine throughout, the machine shown generally has a fixed frame with downwardly extending floor engaging legs as shown. Fixed to these legs are the way support rods 7 which support the end housings 23. The end housings 23 are adjustably fixed to the way support rods 7 by means of the locking screws 24 which clamp the end housings 23 to the ways.
The main shaft 85 is rotatably supported on the frame by means of anti-frictional bearings 25. The main shaft 85 is rotated by means of the sprocket 26 which is, in turn, driven by a reduction transmission and a motor. The main shaft 85 has a gear 27 fixed thereto which is in meshing engagement with a gear 28 which drives the unloading mechanism through shaft 29.
The orientation drum 30 is also keyed to the main shaft 85 and it rotates therewith as does the cap loading mechanism 31.
The cap loading mechanism 31 has the six spaced die slide pins 32 fixed thereto and radially extending thereon and these die slide pins each support an anti-friction bearing in the form of slide rollers 33. These die slide rollers roll on the cam 34. Thus, as the cap loading mechanism 31 rotates, the slide rollers 33 force the cap dies to reciprocate. Thus, when the cap is fed into one ice of the dies at the top part of the rotation thereof, the cap die is forced toward the resistor body with it and the cap is forced onto the resistor body.
The caps and bodies are fed to the respective loading mechanisms by means of the vibratory feeders 11 which feed the caps through cap feed tubes 13 to the respective dies. The vibratory feeder 12 feeds the cylindrical bodies to the body wheel 36. The caps and bodies move down to the respective dies through the respective feed tubes 13 and 14. The cap loading mechanisms are urged away from each other by means of the main drum springs 35.
Each of the cap dies is supported adjacent. a corresponding body receiving notch 36 on the orientation drum or body wheel and in alignment therewith.
Cap die mechanism The cap die mechanism is shown in FIG. 5. After the cap has been placed into the cap die by the cap positioner 41, it is ready to be forced onto the end of the body. The cap die is indicated at 44. It has a cavity 38 therein which conforms to the shape of the cap. The wire lead which is on the end of the cap will be retained in the slot 61 in the cap die 44. The cap die 44 is attached to the die holder slide 46 which has an anti-friction die slide roller 33. The die slide roller 33 is on the end opposite to the cap die opening. This roller 33 is attached to a die slide pin 32 and to a die spring guide 62. The die return spring 45 is slidably attached over the die spring guide 62. The die return spring 45 is contained in a stationary retainer.
The cam support has a cam 34 on which the roller 33 runs. As the cap drum rotates, the roller 33 will follow the contour of the cam 34 and cause the cap die to move inwardly and force the caps onto the bodies. As the roller 33 comes to the lower part of the cam 34, the die return spring 45 will cause the die to retract after the die has moved in to cap the resistor.
Stripping fingers 70 are fixed to the cap drums. A slot is cut on the underslide of each die 44, and the stripping fingers 70 is disposed in the slot. When the die moves forward to cap a resistor body the finger is held in position and performs no function. After capping operations if 'a cap or debris of any sort remains in the die cavity 38, the stripping finger 70 will cause it to be ejected from the die as the die is drawn back over the finger 70 by the capping cam.
Cap loading mechanism.
The cap loading mechanism is best shown in FIGS. 7 and 8. The caps for the resistors are fed down the feed tube 13 to the cap loader 53. As the caps leave the feed tube 13, air which is induced from a nozzle 51 located at the end of the feed tube 13 will force the cap forward and downward into a V-shaped opening 52 in the cap loader. This V-shaped opening 52 is composed of a stationary door 54 and a movable door 55. The movable door 55 is actuated by a link 56 which is connected to a sliding shaft 57 in the cap loader. The end of the sliding shaft 57 is moved by the piston rod of an air cylinder 58 which is connected to air line 59 and has a piston rod connected to shaft 57. The cylinder 58 is actuated by a solenoid valve to give it proper indexing with the movement of the drum. As air is forced into the cylinder 58, the shaft 57 moves and forces the link 56 to open the movable door 55 attached thereto by swinging it around its hinge pin 55 and allows the cap to drop into the cap positioner 41. The cap is now in position to be received into the cap die 44. As each cap is placed into the positioner 41, it is moved into the die by the curved portion of the cap seater 60. As the drum with the die passes the curved portion of cap seater 60, the seater is actuated by its end engaging the main cam and the cap is moved into the die. This procedure is repeated for each cap as it comes down the feed tube into the cap loader.
Unloading mechanism The unloading mechanism is made up of laterally spaced belts 48 supported on pulleys 47, which are driven by shafts 29 in synchronism with the rotation of the main shaft. Each alternate link of belts 48 has a bracket 48A attached thereto. Each bracket 48A has an upward- 1y facing V-shaped surface. As the shaft 85 rotates, each resistor body has a notch 38 therein which is moved into the V-shaped surface of the bracket 48A by stripper bracket 49. The stripping mechanism includes the stripper arm 50, which is swingably attached to the stripper bracket 49, which is in turn fixed to one of the support rods 7. The stripper arm slides along the side of the outer periphery of the orientation wheel 36 and lifts the capped bodies therefrom as they pass.
The link roller conveyor which is made up of belts 48 is supported on conveyor sprockets 47 and has the outwardly facing V-shaped notched members 54 therein. The notches in the notch members 54 receive the capped bodies and will convey them to a suitable repository.
The foregoing specification sets forth the invention in its preferred practical forms but it is understood that the structure shown is capable of modification within a range of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claims.
