Definitions

  • This invention relates generally to lamp-making machinery and more particularly to equipment for applying a cement paste to the internal surface of a base in order that it may be secured to a bulb for constituting an electric lamp.
  • the invention is concerned with a machine applying the principles of nonintermittent or continuous action to the operation of filling a lamp base with cement, as contradistinguished from machines applying the principles of intermittent or indexing action.
  • Lamp-making machinery of the indexing type is thus limited in output by the laws of mechanics; and, discounting incidental improvements, an increase in the production rate must generally be brought about by an increase in the number of machines in use.
  • the principal object of this invention is the provision of a machine applying the principles of continuous or nonintermittent action to the lamp-manufacturing operation of filling bases with cement.
  • Another object of the invention is the provision of an automatic lamp base filling machine of the nonintermittent type permitting a much more eflicient utilization of mechanical operators by comparison with machines of the indexing type, and thereby achieving a much greater productive capacity.
  • Yet another object of the invention is the provision of a lamp base filling machine of the nonintermittent type having much lower power requirements than conventional machines of the indexing type.
  • Fig. 1 is a cross-sectional view of a miniature screw base for a lamp produced in large quantities by the lamp-making industry and for which high speed cementing, such as can be achieved by a nonintermittent type machine, is particularly desirable.
  • Fig. 2 is a simplified mechanical schematic diagram illustrating the over-all functioning of a roller chain and sprocket type nonintermittent base-filling machine embodying my invention.
  • Fig. 3 is a fragmentary plan View of the machine showing a major sprocket carrying filler operators, a contiguous portion of the chain and the apparatus immediately associated therewith.
  • Fig. 4 is a side elevational view of the portion of the machine illustrated in Fig. 3, part of the view being in vertical section along the line IVIV.
  • Figs. 5a, b, c, d, and e are various views of a filler operator which may be used in my basefilling machine.
  • Fig. 6 is a fragmentary plan view of the machine showing the minor sprockets including the air ejector and chute sprocket, a contiguous portion of the chain, and the associated apparatus;
  • Fig. 7 is a side elevational view of the portion of the machine illustrated in Fig. 6, part of the view being in vertical section along the line VIIVII.
  • the cement paste would be defined as a material.
  • the raw materials of the process involved in filling a lamp base with cement comprise a finished base and the cement paste.
  • a base typical of those which my machine is designed to handle is illustrated at l in Fig. 1.
  • This base will be recognized by those skilled in the art as representative of a kind utilized in very large quantities in the lamp-making industry; Itv is of the miniature screw r Edison type and comprises a thin-walled threaded metal shell 2 which is commonly made of brass, but which may also be made of aluminum or other suitable metal.
  • the shell is slightly flared at 3, corresponding to its inner end,.in order to receive a glass bulb.
  • a finished lamp for constituting afinished lamp, and has an opening at its outer end which is closed by a web 4 of plastic insulating material such as glass or a thermosetting type of plastic.
  • a boss 5 at the outer end of the web is mounted on a boss 5 at the outer end of the web.
  • a contact eyelet 5 which provides one terminal of the lamp, the other terminal being provided by the base shell itself.
  • the plastic Web 4 has a hole.
  • the crosshatched area I represents cement paste which is annularly disposed within the periphery of the base shell. The purpose of this cement is to securely fix the glass bulb to the base in the finished product constituting an electric lamp.
  • the specific function of the nonintermittent lamp base filling machine considered in this application is to receive the bases, as illustrated in Fig. 1 less the cement, and to dispose an annular ring of cement within it as shown at i in the figure. It will be understood that each type of base has exact specifications for paste distribution and volume.
  • the insertion of the paste may be accomplished by means of a cam-actuated feed tube supplied with air pressurized cement.
  • the insertion of cement is performed at a work station of an indexing machine and the base may be rotated while the cement is being injected.
  • the bases are automatically fed into and ejected from suitable holding cups.
  • a typical production rate for such prior art intermittent type machines is approximately 4,000 bases per hour.
  • a continuous nonintermittent action lamp base filling machine embodying my invention may have a production-rate of up to 40,000 bases per hour.
  • roller chain and sprocket mechanism A practical mechanism for satisfying the basic requirement above is the roller chain and sprocket mechanism, and it offers many possible arrangements. For instance, two separate roller chain and sprocket mechanisms may be employed, the operators being mounted on the chain of one, and the product. mounted on the chain of the other. The operation of the operator on the product may then be performed during a period of time when the chains are arranged to move in parallelism.
  • Such an arrangement suffers from certain disadvantages such as'misalignment due to sag of the chains, instability of the chains under the action of forces, unequal Wear between the chains and the difficulty of insuring exact velocities at all times.
  • the operator revolves with the sprocket in order to perform its operation on another product carried by the chain at a point rearwardly displaced from the product first considered.
  • a preferred arrangement of a lamp base filling machine embodying my invention is illustrated in simplified mechanical schematic form.
  • the mechanism comprises a roller chain E0 on which are mounted suitable holders for holding the product, that is, the lamp bases of a type such as is illustrated in Fig. l.
  • the chain is wrapped around and engages the teeth of a number of sprockets of which the major sprockets I I and I2 are of a larger size.
  • Sprocket II carries the operators which feed the bases to suitable holders mounted at spaced intervals on the chain I0, whereas sprocket I2 carries the operators which insert the cement or paste into the bases.
  • the chain is arranged to be driven in such a manner that it moves directly from the base feeding sprocket II to the cement inserting or filling sprocket I2, as indicated by the arrows. After leaving the filling sprocket, the chain passes around a driving or power input sprocket I3, and then around a sprocket I4 which operates as a chute through which the lamps drop after being blown out of the holders by means of an air ejector sprocket l5.
  • the feeding operation must occur during the interval of time while the chain moves around the 180 through which it wraps the feeding sprocket I i.
  • the machine is designed to operate at such a rate that the major sprockets make one revolution er second and each carry 12 operators.
  • the output of the machine is twelve cement-filled lamp bases per second or 720 per minute, which gives a total production of 43,200 bases per hour.
  • the feeding mechanism must thus supply twelve bases every second to the chain and align them in a definite pattern so that they may be properly received and held by the base holders.
  • the bases are supplied from an overhead hopper and dropped into a distributing cup which is mounted on the feeding sprocket Ii.
  • the distributing cup has twelve funnel shaped openings equi-angularly disposed around its lower periphery, and the bases fall through these openings into radial V-shaped slides which lead into metering units from whence the bases are injected into the holders carried by the chain.
  • various other mechanisms may be utilized for feeding the bases to the holders, and that they might also be fed by the attendant personnel. Such being the case, the feeding mechanism will not be described in detail in the present application and reference may be had to the above-mentioned copending application for a description of a preferred mechanism ideally suited for the purpose.
  • the filling operation is the most important and critical one of any performed by the lamp base filling machine. Its operation is subject to the following factors and considerations:
  • the mechanism must insert a controlled amount of cement paste into a base with a positive action in order to assure the desired quality of the finished product.
  • the filling mechanism must not function if a base is not present in the holder to receive the paste.
  • the paste must be under control at all times in order to prevent it from escaping at undesired times.
  • the timing of the operation must be directly related to the speed of the chain and occur during the period of wrap of the chain around the filling sprocket.
  • the roller chain I 0 engages the major sprocket I2 and causes it to rotat in a counter-clockwise direction, as indicated by the arrows I 9, at a rate of one revolution per second.
  • the chain comprises a series of links 29 and rollers 2i which are pivotally joined together in a conventional fashion.
  • the holders comprise an L- shaped frame member 23, a pair of jaws 24 and 25 adapted to grip the base and a bell crank 26 for the purpose of operating the jaws.
  • the frame member 23 is secured in suitable fashion to a pair of adjoining rollers in the chain and support the jaws in such fashion that they are capable of pivoting in a plane normal to the plan of the sprocket I2.
  • the jaws are spring forced together and have respectively interlocking spur teeth along their lower portions which maintain them in alignment and cause them to close together in a symmetrical fashion.
  • the structure of the base holders is more fully described in the previously mentioned copending application.
  • the base i may be released from the jaws by operating the bell crank 26; and for that purpose, a roller 27 is mounted on the free end of the bell crank for engaging the cam track 28 during a portion of the period of wrap of the chain around the sprocket.
  • the jaws may be seen in their open or operated state at 26 and 25 at the 150 position on the sprocket.
  • the chain is effectively wrapped around the sprocket from the position indicated at on the drawing to the 300 position.
  • such base holder has an angular velocity identical to that of the sprocket so that it is to all intents and purposes fixed with respect to the sprocket.
  • the machine is designed to fill a base with cement during the period from 90 to 270.
  • the filling of any one particular base is performed by one of twelve filler units 3! which are mounted radially upon the filling sprocket i2 revolving about the stationary shaft 3
  • the filler units 30 will be more fully described shortly with reference to Fig. 5.
  • the cement paste is supplied to the filler units by means of flexiblerubbertubes 32 which receive their supply of paste from a central revolving distributinghead33 mounted on top of the sprocket I 2.
  • the paste is stored below the table of the machine instationary container (not shown in the drawing).
  • the filler units are thus at all times supplied with pressurized cement paste for filling the lamp bases.
  • the amount of paste inserted by the head of a filler unit into a base is determined by the internal arrangement of the operating parts in the filler unit, which parts are put into operation by the radial movement of the push rods 35.
  • the movement of the push rods is occasioned by a harmonic cam 36 mounted on vthe stationary shaft 3!, the coil springs 3'! causing the rollers 33 mounted on the inner ends of the push rods, to bear against the periphery of the cam.
  • Figs. 5a and 5b show the filler operator 3!] in the recessed, or unextended position;
  • Fig. 5a is a plan view of the operator partly in section,
  • Fig. 5b is a vertical section, whereas
  • Fig. 5c is an end elevation view.
  • the unit comprises a housing 33 which is securely mounted on the sprocket, preferably by means of a tongue and groove arrangement it! as can be seen more particularly in Fig. 50. It will be understood that twelve such units are mounted at intervals on the major sprocket i2, and that these units revolve with the sprocket.
  • the moving parts of the unit are actuated by means of the push rod which is normally extended outwardly from the housing ll! by means of the helical spring 31.
  • the roller 38 is adapted to bear on the harmonic cam 36 so as to impart a reciprocating motion to the push rod as the unit revolves with the sprocket.
  • Slidably mounted within the housing s6, is an annular sleeve 52 which is also free to slide with respect to the rod 35.
  • the sleeve 32 is prevented from rotating axially with respect to the housing 40 by means of a long vertical pin 43, which secures it to a tongue 4:3 running in a groove in the upper surface of the housing as may be seen in Fig. 5a.
  • the pin 43 passes through a slot 46 in the rod 35 so that the rod may move to the extent allowed by the slot without interfering with the position of the annular sleeve.
  • the sleeve is forced outwardly to the right by means of a spring 41 compressed between its rear shoulder and the inside surface of the rear wall of the housing 40.
  • the pressurized paste is supplied to the filler unit by means of the flexible rubber tube 32 fitting on the nipple 48.-
  • the nipple is screwed into the annular sleeve 42 and leads the paste into an annular recess provided between the shaft of a plunger 49 and the bore of the annular sleeve 42.
  • This annular space may be seen at 50 and its size is determined by the distance between the forward end of the push rod and the rear side of the expanded front portion of the plunger.
  • the plunger has a limited longitudinal movement with respect to the push rod 35 through the arrangement of the slot 5
  • the annular space 5 assumes its position of greatest extension; This results. from the fact that the small pin 52 has reached the limit of its travel in the slot 5i, the plunger 49 being prevented from moving back any further by its rear end striking the long pin 43.
  • Fig. 5d The operation of the filler unit when a base is absent from the holder is shown in Fig. 5d.
  • the unit is illustrated at the full length of forward movement of the push rod 35, such corresponding to the 189 position of Fig. 3 in the absence of a base in the base holder.
  • the harmonic cam forces the rod 35 forward, that is, to the right in Fig. 5d, the long pin 43 is released and this permits spring 41 to force the anular sleeve 42 forward.
  • the paste is not exposed because of the fact that the nose portion 53 of the annular sleeve is not held back by a base.
  • the annular recess 50 is not uncovered and the aste remains confined within it.
  • Fig. 5c shows the operation'of the filler unit when it encounters a holder containing a base
  • the push rod 35 is moved forward by the harmonic cam, and, in the same manner as before, the long pin 43 is released so that the annular sleeve 32 is now freeto move forward under the action of the spring 41'.
  • the annular slee' e does move forward a slight distance until its nose portion 53 contacts the outer shoulder of the lamp base I.
  • the annular sleeve ceases to move whereas the push rod 35 continues to advance and pushes the plunger 49 forward until its forward face contacts the bottom of the base.
  • the plunger 49 can only move back to the extent allowed when its rear end strikes the long pin 43. Thereafter, the rod 35 continues to move backward and opens up the annular recess 50 again. As the recess 50 reopens, the pressurized paste flows into it from the reservoir through the tubing 32, and the unit is then ready for the next filling operation.
  • This feature also permits compensation for dimensional tolerances and variations in the individual bases.
  • the cam track 28 ends and permits the bell crank 26 to drop down, whereupon the jaws once more securely grip the base while the chain moves it onwards to the succeeding sprockets.
  • a nonintermittent base-filling machine provided with twelve filler units such as have been described can rotate one revolution per second. At such a speed, the machine produces 720 bases per minute or 43,200 bases per hour.
  • the nonintermittent machine embodying my invention provides the same amount of time for idling the bases as the prior art ma chine yet has an output eleven times greater. This is made possible by the nonintermittent motion and the increased number of flller units. In terms of indexing machinery, a production rate of 43,200 bases per hour seems an enormous amount to process. However, it is seen that by having recourse to nonintermittent machinery, such a rate is entirely feasible and does not entail a higher speed in the operators, that is, in the flller units.
  • the base may be ejected immediately from the holder.
  • the heating of the bases may be achieved by means of fire banks as disposed to direct jets of flame on the base while the chain carries it around the power input sprocket I3, as may be seen in Fig. 6.
  • the effect of gravity in disturbing the peripherial distribution of the paste within the shell of the base may be appreciable.
  • this effect may be corrected by so disposing the machine that the bases are held in a vertical plane, that is, with their axes vertical, after leaving the filling sprocket for a sufficient length of time to permit the paste to harden.
  • Another expedient to which recourse may be had consists of providing means in conjunction with horizontal base holders for indexing the bases through a small angle periodically. For instance, this may be achieved by a ratchet mechanism to rotate the base in the jaws each time the jaws are partly opened and closed. Suitable cam devices may be provided along the path of the chain to operate the bell cranks of the base holders and thereby cause rotation of the jaws.
  • the ejecting unit comprises the chute sprocket l4 and the air ejector sprocket IS.
  • the chute sprocket I4 is a free running sprocket driven by the roller chain. It is mounted on a hollow stationary shaft 55 which has an encased flared portion 56 at its upper end serving as a funnel for catching the bases. The bases are blown out of the jaws by the air blast and into the funnel portion 50 through the holes 5? in the side thereof. Thereafter, the bases fall through the hollow shaft 55 and into a suitable chute or receptacle.
  • the air ejector sprocket comprises four nozzles 58 which are mounted on a sleeve 59 fastened to a pinion 6
  • the air ejector sprocket I5 has a stationary central hollow shaft 63 to which air is supplied under pressure, as by means of the rubber hose M.
  • a slot 65 is milled in the shaft 63 in line with the axis of the chute sprocket 14 such that whenever a nozzle passes opposite it, air is admitted to the nozzle for blowing the base out of the holder.
  • the jaws of the base holder are opened and the base is released; this is achieved by means of a cam track 66 which forces the bell crank 26 of the lamp base holder upwards.
  • the base is blown out of the jaws, it falls through one of the holes 51 in the flared portion of chute sprocket l4 and down the hollow stationary shaft 55 into a suitable chute or container under the machine (not shown in the drawing).
  • the jaws will open wide after passing the ejection unit through the action of the cam track Bi and the base will fall out of the holding jaws before it reaches the feeding mechanism. It will be realized of course that suitable control means may be provided to stop the operation of the machine in case a base should stick in the jaws.
  • the ejection unit serves a secondary role as a means for automatically adjusting the tension of the roller chain.
  • the air ejector and chute sprockets are mounted on a sliding unit under the action of a spring 68 which keeps the chain under constant tension and prevents it from sagging.
  • the power input sprocket i3 is mounted on a shaft 69 and serves to drive the chain and the other sprockets.
  • the shaft 63 may be the output shaft of a gear reducer driven by a variable speed electric motor or any other suitable means.
