MACHINE FOR MANUFACTURING CRIMPED PAPER CUPS.
Application filed April 16, 1921. Serial No. 461,855.
To all whom it may concern:
Be it known that I, EDWIN L. ELWELL, a citizen of the United States of America, residing inthe city of Baltimore, State of Maryland, have invented certain new and useful Improvements in Machines for Mannfacturing Crimped Paper Cups, of which the following is a specification.
This invention relates to a machine for producing paper wrappers or cups used in packing or wrappingor as a receptacle for individual candies or pieces of candy, as chocolates, bon-bons and the like; the wrappers or receptacles being usually and preferably in the form of paper discs having a flat circular central portion constituting the bottom of the cup and having a wide margin or edge portion which is crimped or leated to form the wallsor sides of the cup. everal machines for this purposeare known to the patented art, the present invention being understood to relate to certain improvements or to an improved type of machine.
The machine as shown which is an embodiment of the preferred form of'the invention consists of a dial or carrier plate having a step by step rotation and a .plurality of dies with which openings or pockets in the dial register at each dwell in combination with two separate reciprocating heads carrying a cutter and a bumper and punch respectively and timed and placed as hereinafter described, to cooperate with the dial and dies together with means for feeding a web; of material as paper, whereby blanks are cut'from the web of paper by means of the reciprocating cutter acting in cooperationwith one of said dies known as the cutting die and carried by the dial to the other reciprocating head, which crimps the blanks thus cut acting in connection and in combination with the other die, theparts I being so arranged and placed that the dial in its step by step rotation brings each set of blanks cut by the cutter, into cooperative relation with the crimping die to be acted upon as aforesaid. I
An important feature of the machine resides in the crimping means which includes a bumper which strikes the blanks forcing them into the serrations of the crimping diewhere they are held not by positive but by a spring tension provided by means of springs which take up an excessive backlash or play in the bumper mech anism' provided for that purpose, the operabetween the bumper and the die, overcom-v ing the spring tension which tends to hold the bumper against the die and perfecting and completing the crimping action as more fully hereinafter explained.
' Other features of the machine relate to the step by step motion of the dial which is preferably driven in connection With the bumper and punch and may be positioned by the. bumper and punch mechanism or means carried thereby or causing the dial to stop with a pocket or opening carrying the paper blanks in registration with the die and in the path of the punch and bumper.
In order to provide for the cooperation of -the cutter with the dial, means are provided for stopping the cutter or the reciprocating head by which it is carried whenever the dial with its carrier openings or pockets move out of registration or out of alignment with the cutter. This in the present instance is, accomplished by withdrawing a key which connects the reciprocating mechanism carryingthe cutter to its drive shaft.
In the form of the machine shown, the cutter and die are driven by separate belts, the dial as aforesaid being timed to cooperate with both said mechanisms.
In the accompanying drawing I have illustrated a cutting and punching machine for producing paper cups or wrappers emplan indicated Fig. 4 is a detail view of the timing mechanism operating in connection with the reciprocating head which carries the cutter, the dialserving to maintain the proper timin relation between the cutter and dial.
Fig. 5' is a detail of the clutch mechanism embodied in the timing apparatus.
Fig. 6 is a section on the line 6'6 of Figure 5.
Fig. 7 is a vertical central section through multiple.
shown in section.
,Fig. 9 is a horizontal section on the line 9-9 of 'Fig. 2.
Figs. 10 and 11 are views of the cup or wrapper made by the machine.
Referring to the drawings by numerals, each of which is used to indicate the same or similar parts in the different figures, the machine as shown comprises two reciprocating heads indicated in a general way by re ference characters 1 and 2 respectively, an in termittent'ly rotating dial 3 andsuitable cutting and forming dies.
The reciprocating head 1 being the cutting head and the reciprocating head 2, the die pressing or bumping and punching head. In the form of the invention shown, the cutting and die pressing heads are separately driven. The reciprocating head 1 being driven by means of a Suitable belt 5, which engages a pulley 6 on a shaft 7, which sha ft at the end 8 is provided with an offset or crank 9 carrying a crank pin 10 which actu ates a connecting rod 11, connected at its lower end by a suitable wrist pin and bearing 12, to a sliding cross head 13 which .reeiprocates in suitable stationary upright guides 14. It-will be noted that as shown.
the throw of the crank 9 is adjustable by means of an eccentric 15 enclosing and surrounding the crank pin' 10 within the connecting rod bearing 16 atthe upper end of y the connecting rod. The manner of adjustment is by loosening the bearing 16 and rotating the eccentric. The cross head 13 carries a cutter 17 which cooperates with a circular die l8,cutting circular blanks, or blanks of the desired shape according .to the form of the cutting die from a web or webs 19, fed over the die and beneath the cover plate 20 as hereinafter described. The webs are ordinarily fed in Referring now to the opposite end of the machine, particularly to the die pressing and punching head 2, the die pressing and punching mechanism is driven by means of an ordinary belt and pulley 220 and 21, the
belt being in the illustration Fig. 1, shown as in engagement with the loose pulley 22 to which the belt may be shifted when the machine is idle. The pulley 21 is secured to drive shaft 23 which has a suitable bearing in the frame of the machine at 24,- and carries-a toothed gear 25 rigidly secured to the pulley and meshing with a toothed gear 26 on a shaft 27 The cutter has, suitably spaced bearings 28, 29 in the frame of themachine.-At the opposite end of the shaft 27 from the toothed gear 26 and mounted on and rigidly secured to said shaft 27-, is an eccentric 31, see Fig. 7 encircled by an eccentric strap 32 carrying an eccentric rod 33 connected by means of a wrist pin 34 to a reciprocating cross head 35, which travels in a vertical path in suitable upright guides 36.
An important feature of the invention relates to the provision of a considerable clearance 87 between the strap 32 andthe eccentric, the eccentric strap being given a downward tendency by means of spiral springs 38 attached at their upper ends 39 to the strap and at their lower ends to stationary points on the machine at 40, the springs being normally under tension. This permits the mechanism to strike or to bump it on the die imparting an initial crimp, the positive pressure being removed as the eccentricrotates past its lower dead point and a resilient spring pressure being maintained which permits the paper to be drawn through the die by the punch, overcoming the spring pressure and producing a most satisfactory final crimping action as hereinafter described.
The bumping or upper bumping die carried by the-reciprocating cross head 35 is illustrated in Figure 7 in section and in Figure 2 in elevation, and indicated by reference character 41; it has a central aperindicated by reference character 45 are serrated in corresponding radial ridges and grooves to produce corresponding crim s or pleats in the paper. The position 0 the upper or bumping die 11 relatively to the eccentric rod 33 is adjustable by means of an eccentric 46 enclosing and encircling the wrist 'pin 34 within the eye 48 of the wrist pin bearings at the upper end of the cross head 35; the manner of adjustment by retation of the eccentric will be understood.
To actuate the punch 43 the eccentrie31 is provided with a crank pin :47 projecting from its outer face. The crank pin operates a connecting rod 50, the wrist pin 51 and sliding cross head '52, which likewise travels in guides 36. The punch 43 before mentioned, is mounted at its upper end in the lower end of the cross head 52 havingin.
,fact a. shank 53 seated inan aperture in the crank pin 47 as shown is set from 45 to 60 back of the point of maximum throw or greatest radius of the eccentric as indicated by referenoecharacter 56 in Fig. 2; the
-- pressing die to strike its blow at the bottom dead point of the ecce ntric acting with a positive pressure when all the back lash or play is taken up and then, i. e., after the eccentric 31 passes the dead point, the bump er or upper bumping die 41, is held in contact with the paper by the action of the springs. After the positive pressure of the bumper has been releasedby rotation of the eccentric and while the paper is held. between the upper or bumping. die 41 and the lower or stationary pressing die 44 by the tension of springs 38, the punch 43 comes in contact with the center of the paper blanks tending to pusli them downward through the apertures in the lower stationary pressing die 44,- the same being indicated by ref erence character 49. Thls causes the edge portions of the blanks to be drawn with a considerable degree of tension through the cooperating serrated surfaces 45, completing and perfecting the pleats or crimps in the paper as aforesaid.
Having further reference to the die pressing and punching head 2, the shaft 27 carries a sprocket (see Fig. 1) which drives a chain 62 which in turn meshes with a sprocket 63 secured to a shaft 64 mounted in suitably spaced bearings 66 and carrying a web feeding roller 67. Cooperating with the roller 67 is an upper feed roller 68 on a shaft .69 mounted in bearings 70 suitably spaced as aforesaid, it being understood that the bearings 70 and 66are mounted in vertical ways or slots 71 in suitable standards or uprights .72, the bearings being semi-circular, the lower bearings 66 being turned up and the upper bearings 70 turned downward, also set screws 73 are threadedinto the-ends of the uprights 72 bearing at their lower ends against the semi-circular bearings'7O whereby suitable tension or pressure is applied to the rollers regulating the contact pressure and providing suitable ad- 'justment to the thickness of Web or multiple web passed through the rollers. The upper roller 68 is driven-by means of meshing tooth gears 74, 75 on the lower and upper roller shafts 64, 69 respectively.
The rollers 67, 68 as aforesaid are intended to feed the paper web or webs forv the machine uses the paper in multiple thickness in its normal operation, the feed being continuous and suflicient to supply a length of paper equal to the diameterof the blanks plus asurtable margin. preferably from a sixteenth to an eighth of an inch between the cuts for each -Quarter turn of the dial, i..e., for each. step in the rotation of the dial as hereinafter described. The die pressing or bumping and punching head 2 also includes means for imparting to the dial 3 which in this instance has four pockets or apertures 275 equally spaced by arcs of 90 the step by step rotation aforesaid which places these pockets in turn in exact registration with the cutting die 18 and the crimping die or stationary pressing die 44 and in alignment with the cutter l7 and the bumping and punching members 41 and 43 which are as aforesaid in alignment with the cutting die 17 and stationary pressing die 44 respectively. It should also he noted that for efficiency and facility of operation the respective elements described are so arranged that. the two opposite holes or pockets 275 spaced by 180 are brought simultaneously in registration, one with the cutting die and cutter, the other with the pleating die and bumpcr and punch. To'this end the shaft 27 of the reciprocating head 2 carries a bevel gear which meshes with a bevel gear 81 on an upright shaft 82 mounted in suitable bearings 83 in the frame, which shaft. 82 carries in its lower end ,an intermittent or mutilated gear 84 having a portion of the circumference 85 of a length corresponding to one quarter of the circumference of the dial 3 toothed as shown,.the remainder of the circumference 86 being smooth. At the end of the toothed portion 85, a tooth 87 is provided of double width and the dial 3, which has its circumference toothed at 88 to cooperate with the intermittent gear, is provided at intervals amounting to one quarter of the circumference or with similar teeth 89 .of double width and corresponding space 9.) adjacent the said teeth to receive the double width teeth on the intermittent gean.
The double teeth are providedfor the purpose of taking up the initial stress incident to starting the dial after each dwell. The double tooth 87 'is shown in contact with a double tooth 89 on the dial in Fig. 8. In this position the dial is about to start a quarter rotation. the rotation of the dial being counter clockwise'as illustrated. The tooth of the dial immediately adjacent cach space 90 in the form illustrated is cut away at 91 to provide for the meshing of the gears.
It will be apparent that when the dial comes to the end of each quarter rotation bringing the pockets or holes 75 into regis tration with the dies, that it has consider able moment of rotation. To arrest the rotation of the dial and position it with the pockets in registration with the dies and alignment with the bumper and punch and cutter, the cross head'35 which carries the bumper is provided with a stop pin 95 carried in a suitable socket 96 in the cross head. The stop pin 95 is set in a projectcorresponds to a pocket so that the pin 95 engages the blocks in turn stopping the dial in exactly the position to locate the pockets in turn in registration with the dies and in alignment with the bumper, the holes serve to lock the dial at each dwell preventing displacement. Further the pin 95 on account of its length continues in engagement with the dial sometime after the bumper cross head starts to move upward when the punch has entered the die. The continued upward traverse of the bumper cross head releases the dial as the double tooth 87 completes the rotation and comes in contact with the next double tooth 89 on the dial. The meshing of the teeth on the dial with those of the intermittent gear accomplishes another quarter revolution moving the next pocketinto registration with the dies, the parts being so timed that the punch is completely or substantially withdrawn prior to the meshing of the tooth 87 so that it is moved from the path of thedial before the latter can come in contact with it.
Figs. 4, 5 and 6 illustrate the cutter timing mechanism by means of which the cutter is timed in exact correspondence with the step by step rotation of the dial so that at each dwell of the dial the latter is positioned with one of its pockets beneath the cutting die and each cutting operation serves to deposit in a pocket of the dial, which pocket is held in registration with the cutting dial, acut blank or a number of cut blanks equal to the number of sheets composing the web.
To this end the pulley 6 which drives the shaft 7 which actuates the reciprocating cutter is mounted on the shaft to rotate relatively thereto and means is provided whereby the pulley is keyed t0 the shaft at intervals and released providing for the actuation of the reciprocating cutter at intervals corresponding to each dwell of the dial, during which the holes or pockets in the dial are positioned in alignment with the cutter and the cutting die. The face of the pulley adjacent the shaftas shown in Fig. 5 and in dotted lines in Fig. 6 is provided with four notches or indentations 100 adapted to be engaged by a key or bolt 101 carried by a collar 102 which is keyed to the shaft by means of a key 103 to ro- .tate therewith. The key 100 is mounted to slide in the collar in the direction of the axis of the shaft being to this end seated in a groove 104.- in the collar and held by suitable cover plates 105 secured by any suitable means.
A spring 106 seated in an aperture 107 in the key and bearing againstthe end wall 108 of the groove 104 serves to impart to the key a tendency to slide to the left in the groove causing it to protrude from the collar and enter one of the notches or depressions 100. The key is also slotted transversely as to its outer face at 208 and the collar hasa peripheral groove 109 and the key has a follower or dog surface 110 at one side of the groove in the key which projects into the groove 109 in the collar when the key isadvanced, i.'e., projecting from the collar into one of the apertures or depressions in the pulley. Cooperating with the follower or dog 110 is a cam 111 having a cam surface 112, the cam being formed on the ley er 113 which is intermediately pivoted at 114 on a suitable stationary support and adapted to swing into and out of the groove and into and out of the path of the dog or follower 110.
The shaft 7 has a right handed rotation as seen from the left in Fig. 5 tending to bring the dog or follower 110 into contact with the cam surface 112 when the cam is in the groove. The action of the cam on the follower throws the key to the right in Fig. 5 withdrawing it from the notches or depressions in the face of the pulley and: releasing the shaft from the pulley so that the shaft tends to dwell with the follower in contact with the cam and with the cutter in withdrawn or upper position. lVhen the cam is removed from the groove the key 101 is released, being projected by'the pressure of the spring 106 into a notch or depression 100 of the pulley 6 which is in continuous rotation locking the pulley to the shaft, causing the shaft to rotate and actuate the cutter. I
The cam lever 113 is in part controlled by a spiral spring 116 attached at one end to the lever at the end opposite the cam 112 and to a fixed point 118 on the frame. The end 117 of the lever is alsopivotally connected to a rod 119 which is connected at its opposite endto the swinging end 120 of. a bell crank lever 121 pivotally mounted at 122 on the frame and having a depending arm 123 engaged by a sliding rod 124 in suitable bearings 125, 126 in the frame, which rod is normally controlled by a spring 127 coiled about the rod and hearing at one end. against the bearing 126 and at the other end against the collar 128 pinned on or otherwise secured to the rod. This rod '124 normally projects over and along lugs 130, four in number, that is, corresponding in number to the pockets 75 and so related to the pockets that each lug 130 in turn comes in contact with the rod 124 thrusting it to the right as seen in Fig. a, swinging the cam 111 out of the path of the follower or dog 110, releasing the key 101 permitting it to engage the pulley 6, wherey a single rotation is imparted to the shaft 7 resulting in a single reciprocation of the cutter, causin it to operate once and cut a single blank r set of blanks from the Web, it being understood that the lugs 130 are so related to the pockets or holes 75. and the cutter is so timed as to operate during the dwell of one of the pockets 7 in registration with the cutting die and in alignment with the cutter.
The rotation of the shaft 7 is arrested by the release of the key and by a brake to be described. The release of the key is accomplished at the end of each rotation of the shaft 7 by the cam 111 which is re turned immediately to the groove 109 by the action .of "the spring 16 when the, lug 130 passes out of contact with the end of the rod 124 which is at the end of the dwell of the dial. The cam thus engages the follower surfaces 110 on the bolt 101 with.- drawing the bolt, releasing the pulley and. holding the bolt in Withdrawn position till the next lug 130 comes into operation.
The brake is illustrated in Figs. 1 and being indicated by reference character 135. It'consists of a circular band which is split and drawn together by means of a screw 136 engaging the separate ends. The band is provided with suitable brake lining 137 which bears against a drum 138 on the shaft" and the band is further provided with a projecting arm 139- which engages a fixed portion of the frame at 140 providing the desired retardation which immediately stops the shaft when it is released from the pulley by the withdrawal of the key..
A suitable take-01f is provided which serves to remove the cut web from the machina and to prevent its accumulation in the vicinity of the cutter. This take-off may consist of a roller 141 driven by a belt 142 from a pulley 143 ion the cutter shaft 7.
In operation the paper is fed by means of the rollers 67, 68, the feed preferably beingcontinuous and at a rate which provides in excess of the dimensions of the blanks 'a sufficient margin, something lessv than a quarter of an inch to hold the waste together and in line so that it may be conveniently drawn from the machine, the web being also for this purpose slightly wider than the out. It is easily understood that the flexibility of the paper web will permit it to buckle and take up the portion fed when the cutter is down, the web being in. turn released and caused to flatten and thrust its front edge forward when the cutter is withdrawn.
The operation of the cutter 17 in connection with the cutting die 18 and the timing time'of the cutting stroke, receives the cut blanks and carries them to the bumping and crimping station where they are acted upon by the pressing die 44, the bumper or bumping die 41 and the punching or drawing die 43.
In the form of the invention shown the pockets 75 are merely holes in the rotating dial 3, the blanks being supported on and slid over the face of a stationary table or plate 150. With the pockets arranged at 909 as shown and the bumping and cutting sta tions 180 apart there are necessarily two stations, one at the front and one at the rear where no operation takes place. The relative location of the pockets, the number of pockets in the dial and the relative location of the cutting and pressing members, alsothe timing of the parts are widely variable and may be regarded as matters of selection or design. s
As aforesaid the bumper precedes the punch, being set some 30 to ahead of it and also the bumper actuating mechanism is constructed with a considerable amount of play or 'back lash which is taken up by springs 38 so that after the stroke of the bumper when the positive thrust of the mechanism is released, the bumping die is held against the paper pressing it against the stationary die by the action of the springs giving a resilient or yielding rather than a positive grip so that the punch which follows the bumper serves to draw the paper through and between the cooperating serrated surfaces 45 creasing or crimping the 4 paper much more effectively than it can be done. by direct pressure- The adjustments described in this connection compensate for any desired thickness of web or variation in thickness.
-The cut waste is removed by any suitable take-off mechanism as aforesaid, indicated and described in connection with reference characters 140 to 145.
It is also noted that the feeding mechanism provides for adjustmentof the rolls as to spacing andpressure so -that;web of any desired tlnckness. can be used, meaning that any number of sheets which can: be
properly out and crimped may befed through the machine. Paper cups or wra pers which, constitute the product of t e machine indicated by reference character 160 are shown in the form of a single cup Fig. 10 and a plurality of cups in Fig. 11,
the latter in the arrangement which they come from the machine.
Important advantages of the machine are convenience for arrangement, the perfection of the product, particularly as to efficiency of the crimping operation, universal adjustability and extra length of life and possibility of cheap construction due to simplicity of design.
