ENVELOPE COUNTER Filed April 18, 1965 I 2 Sheets-Sheet 2 'Tlciju- BY7-M$M ATTORNEY United States Patent 3,199,426} ENVELOPE (COUNTER Jack M. fiiccone, Westbury, N.Y., assignor to F. L. Smithe Machine Co., Inc, New York, N.Y., a corporation of New York Filed Apr. 18, 1963, Ser. No. 273,945 1 Claim. (CI. 9393) This invention relates, in general, to envelope making machines, and in particular to an improved system for automatically segregating a group of stacked envelopes into packs of predetermined number.

The present invention provides a means for accurately and automatically determining a preselected number of envelopes and distinguishing each group of such envelopes from the other. This invention is an improvement over previous systems, such as is illustrated in co-pending application Serial No. 103,473, filed April 17, 1961. In that application a device for stacking finished envelopes in stacks of precise and predetermined number and banding each stack is provided. In the aforesaid application the banding mechanism is laterally offset from the line of envelope delivery coming from the preceding folding machine. In the device of that application a stack of envelopes of predetermined number is removed periodically from the direct feed line of the envelope machine and shifted laterally to an adjacent device which automatically bands each segregated pack of envelopes.

In the present invention lateral movement and subsequent banding is not desired. Rather, it is desired to feed a stack of envelopes in a direct line as in the prior art, and at the same time segregate the stacked envelopes in groups of predetermined number. Thu-s, a system is herein provided for so determining a preselected number and segregating each such number of envelopes from the other.

Accordingly, it is an object of this invention to provide an improved envelope stacking machanism.

It is a further object of the present invention to provide an envelope stacking device which automatically segregates the stacked envelopes into packs of predetermined number.

It is another object of the invention to provide a system for counting envelopes as they are delivered by an envelope machine and cit-setting selected envelopes at predetermined intervals.

Another object is to provide an improved envelope delivery mechanism which facilitates the subsequent manual banding of envelopes into packs of predetermined number.

Another object of the invention is to provide an improved envelope delivery mechanism which facilitates the accurate counting of the envelopes as they are placed into a shipping container by the machine operator.

The various features of novelty which characterize the invention are pointed out with particularity in the claim annexed to and forming a part of this specification. For a better understanding of theinvention, its operating advantages and specific objects attained by its use, reference should be had to the accompanying drawings and descriptive matter in which there is illustrated and described a preferred embodiment of the invention.

In the drawings:

FIG. 1 is a diagrammatic perspective view of the present invent-ion with a portion of the prior art in schematic form;

FIG. 2 is a plan view of the detecting and actuating device and a portion of the envelope stacking mechanism;

FIG. 3 is a vertical section taken along the lines 3-3 of FIG. 2; and

FIG. 4 is a vertical section taken along the line 44 of FIG. 2.

Referring to the drawings and in particular to FIG. 1,

there is shown .aportion of an envelope stacking mechanism 1t), wherein envelopes 12 are carried by conveyor 14 from an envelope forming mechanism (not shown) t the envelope stacking mechanism.

In FIG. .1, there are shown schematically, laterally offset from the envelope stacking machine, selected portions of the banding mechanism of applicants co-pending application Serial No. 103,473, mentioned hereinabove. In that application, mechanism partially illustrated at 16, removes preselected numbers of envelopes from the en velope stacking station and moves them, as a unit, laterally to an offset position. Feed cams 18, knife roller 26 and applicator arm 22 cooperate to move a wrapping band (not shown) and apply a spot of glue thereto at predetermined intervals. Knife 26 serves to severe the band at predetermined intervals. Pushers 28 serve to move the laterally transposed pack of envelopes and the severed band between the opposed band folding arms 39 and 32. A filler plate 33 allows for conversion of the stacking machine from the offset feed system to an inline delivery system as contemplated by the present invention.

In lieu of offsetting stacks of envelopes as in the device of application Serial No. 103,473, the present invention contemplates inline movement of the envelopes to the termination of the envelope stacking machine.

As in the prior art devices of this type, the envelopes 12 are fed between conveyor belts 14 and 14', which sandwich the envelopes therebetween to hold them securely in place, to the vicinity of aligned slotted

stacker wheels

34, 36 and 38. Each slotted wheel includes a plurality of spirally extending fingers 40 which form slots in the periphery of the wheels. The

slotted wheels

34, 36 and 38 are mounted on a shaft 42, which is rotated in precise timed relationship to the mechanism of the envelope forming machine. Drive chain operatively connects shaft 42 with shaft 43, and drive chain 47, which also engages shaft 42, is connected to a drive mechanism (not shown). As each envelope is moved forward by the conveyor the envelope is slipped into a parallel set of slots formed by the extending fingers 40. After the envelope enters a slot, it is carried around on the wheels until the seal flap edge of the envelope strikes delivery table 44-.

Tabs

35, 37, 39 and 41 extend to Within the radius of

wheels

34, 36 and 38 to enable the table to receive the envelopes. Thus, it will be understood that as the slotted wheels rotate against the table 44, they bring the envelope 12 to a vertical position with its seal fiap edge downwardly on the delivery table over which the now vertically stacked envelopes are moved to the succeeding section of the stacking apparatus (not shown).

A radiant energy source 46, connected to a suitable power supply 48 is positioned just beneath the horizontal plane of envelopes 12 and aligned with a conventional detector and counter 50, whereby the detector is capable of sensing a beam of energy 51 transmitted by said energy source 46. Energy source 46 is suitably secured to supporting element 53. Conveyor belts 14 and 14' each include two sections spaced apart from each other, thereby providing an uninterrupted path for the beam of energy in the space between each envelope, as seen in FIGS. 2 and 4. Detector is also electrically connected to power source 42$. Supporting element 52 provides a foundation for the positioning and attachment thereto of detector 50.

As can'be seen more clearly in FIG. 2, a solenoid 54 affixed to supporting element 52 includes a solenoid arm 56 r-otatably attached to one end of yoke 58. Yoke 58, in turn, is rotatably mounted upon fulcrum 60 which is also secured to supporting element 52. The other end of yoke 58 is securely affixed to offset arm 62, A U-shaped bracket 64 is affixed to supporting element 52 and provides a support and guide for offset arm 62. A coil spring 66 affixed by one of its ends to arm 62 abuts one anasaao end of U-shaped bracket 64 in such a manner as to tend to bias oifset arm 62 outwardly from the line of envelopes 12. To the end or" offset arm 62 there is affixed offset bar 63, which is aligned parallel to the line of envelopes 12- Thus, when oifset bar 68 is moved inwardly toward the line of envelopes 12, the offset bar 68 will engage any envelope in the position shown (FIG. 2), spaced apart from and parallel with bar 68, after the envelope has left the control of conveyor belts 14 and 14'. The offset bar will then move the envelope to the position indicated by the dotted lines FIG. 2), against check bar '74? just as the envelope enters the slots formed by fingers 44 Check bar 70 is alfixed to support element 72, which in turn is secured to supporting element 53.

it should be noted that a solely mechanical type of detector and counter may be employed in lieu of the electronic means embodied herein.

Turning now to the operation of the system enco passed by the present invention, as each envelope 12 cuts a beam of energy 51, the interruption is sensed by detector 5h. After a predetermined number of interruptions by the passing envelopes has been sensed, detector 56 will trigger a signal which is transmitted to solenoid 54. Solenoid 54 is thereupon actuated by the signal to thereby pivot yoke 58 on fulcrum 60 in the direction indicated by the appropriate arrow. Thus it can be understood that the subsequent motion of offset bar 68 will push an envelope positioned adjacent plunger 68 in the direction of check bar 70. The envelope is then moved along in the conventional manner as described hereinabove by the slotted wheels and fingers 40 to a vertical position on table 44. However, the selected envelope engaged by oflset bar 68 is now spaced outwardly from the normal line of envelopes to indicate to an operator that there is a predetermined number of envelopes between each of the offset outwardly extending envelopes.

It should be understood that the detector 50 is of the type that may be adjusted by means (not shown) to actuate solenoid 54 thereby providing for the segregation of any predetermined number of envelopes required for grouping by the operator.

Thus it will be seen that the present invention provides a system for grouping a predetermined number of envelopes and setting them off so that the operator may be able to segregate each of such groups of envelopes for subsequent manual banding thereof into packs of envelopes of predetermined number, or to facilitate the accurate counting of the envelopes as they are placed in a shipping container by the machine operator. The system anticipated by the present invention is fully automated and does not require the attention of an operator once the detector has been set for sensing the desired number of envelopes.

While a specific embodiment of the invention has been shown and described in detail to illustrate the application of the invention principles, it will be understood that the invention may be embodied otherwise without departing from such principles.

What I desire to cover by Letters Patent is set forth in the appended claim:
