Definitions

  • This invention relates to mechanism for transferring electron tube assemblies from a preheater to the peg of a sealing machine and for adjusting parts of such an assembly with respect to one another.
  • assemblies consisting on the one hand of bulbs with attached exhaust tubulation and on the other hand of stems with mounts afiixed thereto are preheated in a long chamber provided with electric heaters, the assemblies being carried on a conveyor traversing the chamber.
  • the bulbs are telescopcd over the mounts but are spaced from the stem to allow hot gases to pass freely through the exhaust tubulation, through the interior of the bulb and out between the bulb and stem.
  • the mechanism for preheating the assemblies is positioned close to an indexing turret provided with pegs to carry the assemblies around past mechanisms which seal the bulb to the stem. To effect this result it is necessary to preliminarily thrust the bulb down over the mount and to a position where the bottom of the bulb is opposite the stem.
  • FIG. 1 is a perspective view of the new transfer and pusher mechanism showing its relationship to the sealing pegs of a bulb to stem sealing machine, with parts in section.
  • Fig. 2 is a front view of the transfer and pusher mechanism, parts being shown in section.
  • Fig. 3 is a fragmental sectional view of a motor for lifting certain parts in the mechanism and its connections.
  • Fig. 4 is an elevation of the mechanism, partly in section, taken at right angles to the view shown in Fig. 2.

  • an endless link chain conveyor mounting equally spaced resilient clasps 12 which releasably retain the exhaust tubulations of tubulated bulbs.
  • This chain traverses a preheater chamber '14 of known construction of which only the end portion is shown and is loaded by an operator at the other end of the run of the chain.
  • the chain is indexed in synchronism with the indexing of a receiving mechanism here illustrated as a turret 16 of a sealing machine, which turret carries equally spaced pegs States Patent 18.
  • the chain passes around an end sprocket 20 sup ported by a channel bar 22 running substantially the length of a run of the chain.
  • the side panels are adjustably fixed longitudinally of the bar by means of plate ribs 28 on the sides of the channel bar fitting in grooves 30 of the panels 2 and 26 and by reason of bolts 32 passing through slots 34 in the panels and threaded into the channel bar.
  • the panels are further held spaced apart by an intermediate plate 36 suitably fastened within grooves in the panels 24 and 26 and by a base plate 38 also suitably fastened in grooves in the side panels as by bolts 40.
  • the space between the under face of the web of the channel bar 22 and the upper face of the intermediate plate 36 affords space for the lower run of the chain conveyor, stripped of its assemblies.
  • the structure is further reinforced by a rear cover plate 42 fastened to the side panels and to the intermediate and base plates, the rear plate extending upwardly only to the level of the intermediate plate 36 to allow space for travel of the lower run of the chain.
  • a pair of guide rods 44 Spanning the space between the plates 36 and 38 is a pair of guide rods 44 having reduced ends 46 lodged in holes 48 in the plates.
  • a platform 5% Slidably mounted on these rods is a platform 5% having an offset portion 52 forming a jaw housing, the housing being provided with a cover plate 54 bolted to the housing.
  • the platform is provided with bronze bushings 56, held in place by conventional means, as by a collar 58 fastened to the bushing and butting against an enlargement 60 on the platform or carriage, the bushing also being enlarged at its upper end to engage the enlargement.
  • a double ended fluid motor 62 of which the top cap 64 is provided with an externally threaded neck 66 extending through an opening in the base plate 38 and fastened to the plate by a nut 68.
  • the inlet and exhaust conduits 76 to the cylinder of the motor are connected to valves (not shown) under control of the indexing movement of the sealer.
  • the upper end of the piston rod 72 of the motor is threaded into the platform 50 midway between the guide rods 44, a lock nut 74 being provided to prevent undesired separation of parts.
  • the downward movement of travel of the carriage is limited by any suitable means, as by the limit of travel of the piston in the fluid motor 62.
  • the platform as will be seen in Fig. 4, to the right of the guide rods, is at a slightly lower elevation than the portion to the left of the rods and provides a seat for a horizontal motor 76 which may be an electromagnetic motor but is preferably an air motor.
  • the motor is fastened to the platform by bolts 77 and has a piston 78 and piston rod 86.
  • the rod 80 passes through a bearing 82 forming part of the cover plate 84 of the motor which plate is fastened to ears 86 on the cylinder by screws 88.
  • the piston rod is threaded into a cam bar and secured thereto by a set screw 92.
  • the piston 78 is urged to the left in Fig. 5 and to the right in Fig.
  • a conduit 98 leads motive fluid, such as air, under control of indexing movement of the sealer, to the rear of the piston through a suitable fitting 1%.
  • the rear cover plate 42 of the transfer mechanism is suitably slotted as indicated at 102 in Fig. 2 to permit movement of the motor fluid lead-ins as the platform 56 moves up and down.
  • the bar 90 at its free end tapers to an edge and provides two cam surfaces 104 operative on the rear portions of jaw arms or levers 106 pivoted on a press fit pin 108 on the offset portion 52.
  • Each of these levers has an antifriction roller 110 at one of its ends to be engaged by the cam surface 104 and an exhaust tube engaging jaw 112 at the other end, with the jaws extending beyond the edge of the platform.
  • the jaws are elongated in the direction of the tubulation to be grasped to form vertical grasping faces and are normally kept separated by coil springs 114 each having an end seated in a recess in an arm 106 and each having the other end seated in a recess in a block 116 fastened to the offset jaw housing 52.
  • the jaws 112 are shown as having been advanced toward each other against the action of the springs by reason of projection of bar 90 between the rear ends of the jaw levers.
  • the jaws 112 Upon application of fluid pressure to the motor 76,the jaws 112 will be forced together. Upon release of pressure the spring 94 will retract the cam bar 90 and the springs 114 will separate the jaws.
  • the conveyor will be indexed to orientate a tubulation of an electron assembly between the jaws and opposite the long grooves in the jaws.
  • the jaws thereupon close on the tubulation and the platform moves downwardly to thrust the assembly onto a peg on the sealer which in the meantime has indexed to a position directly below the tube assembly.
  • the jaws withdraw the tubulation from the resilient clasps on the chain conveyor.
