Box-FILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 482,542, dated September 13, 1892.

Application filed September 25, 1891. Serial No, 406,844. (No model.)

To all whom, t may concern.-

Be it known that we, WILLIAM H. BUTLER and WILLIAM R. LANDFEAR, citizens of the United States, residingat Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Box- Filling Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to boxfilling machines, and especially to machines used in lilling that class of boxes known as slide-boxes, in which thebox proper is inclosed within a tubular cover or sheath.

The object of the present invention is to improve the general construction of this class of machines and the groups of mechanism employed therein, and especially to provide a machine in which the entire operation shall be automatic, the box being formed from a blank or web, filled with the material or articles to be packed, inolosed within the tubular cover or sheath, which is automatically brought into position for this purpose, and the coveredbox sealed by a sealing-strip of paper or similar material, which may be previously prepared, but is preferably formed from the web in the machine.

The machine embodying the invention has been constructed and is designed t'or packing cigarettes, and will be described as a cigarettepacking machine; but itwill be understood that -it is applicable, also, to packing other articles or material in boxes of similar form and that various parts of the mechanism may be used in box-filling machines of other classes orwith mechanism of other form in machines of the same class.

For a full understanding of the invention a detailed description of a machine of the preferred form embodying the same will be given, reference being had to the accompanying` drawings, forming a part of this specification, in Which- Figure 1 is a front elevation of the machine in its preferred form. Fig. 2 is a side elevation showing the box-forming and cigarettefeeding mechanisms. Fig. 3 is a plan view. Fig. et is a horizontal section taken above the carrier.

Figs. 21 to 2G show a modification in which the boxes are formed from blanks fed from a magazine and the sealing mechanism is omitted. Fig. 21 is a iront elevation similar to Fig. 1. Fig. 22 is a plan view. Fig. 23 is a horizontal section ot the box-blank magazine, showing the devices for delivering the bottom blank to the carrier. Figs. 24, 25, and 2G are sections on, respectively, the

lines

21,25, and 2G of Fig. 23 Figs. 27 to 31 are diagrams, partly in section, showing the different steps in forming the product.

The frame of the machine may be of any construction suitable to support the operating parts. As shown, it consists of a standard A, carrying a base-plate B, provided with brackets or arms C D, upon which, respectively, the box-forming and box covering and sealing mechanisms are supported.

Upon the base-plate B is mounted the carrier E on a shaft F, supported inside the hollow standard, by which the boxes areV carried to the different co-operating mechanisms, this carrier being rotated by an arm 10, provided with a bowl, which engages grooves or slots 11 on the under side of the carrier, so as to move the latter forward one step at eac-h ro- ICO tation of the arm 10, the latter being carried by a vertical shaft Gr, which is operated from the main driving-shaft of the machine H tinuation of the arm 10 on the opposite side of the shaft, this arm 13 being connected by alink 14 to a crank-arm 15 on shaft 16, which carries an arm 17, by which the plunger for removing the filled box from the carrier and inclosing it in the cover is actuated. The shaft 16 carries, also, an arm 1S, provided with a bowl 19, which runs in a groove 2O in a lever 2l, pivoted at 22 and connected by a link 23 with the plunger, by which the covers are removed from the cover-magazine. The arm 13 carries abowl 24, which runs in a groove 25 in one arm of a lever 26, pivoted at 27, the other arm of which actuates the plunger for advancing the covers into position to receive the filled boxes.

The carrier E yis provided on its upper side with a series of holders M, in which the boxes are held during the operation of filling and from which they are removed bya plungerin covering. These holders M t'orm, also, matrices, with which a die co-operates to form the blank into a box. The holders are equal in number to the feeding-grooves 11 on the under side of the carrier, so that the amount of feed is equal to the distance between two holders, and at each step forward different holders are brought into proper position for co-operation with the other parts of the machine. A strong spring-catch S engages the grooves 11 successively and insures the accurate positioning of the holders aftereach feeding movement. As shown,the carrier is provided with six holders; but it is evident that this number may be varied, as desired, and all the operations of the machine shown may be performed successively with a carrier provided with but three holders, which successively assume the proper positions for receiving a box, filling the box, and removing the box from the carrier for covering. About this rotating carrier we group in proper position for cooperation therewith the various mechanisms which form the com plete machine, these mechanisms being` the box-forming mechanism or mechanism for forming and delivering to one of the holders M a box to be filled, box-filling mechanism by which the cigarettes are delivered to the box, a covermagazine, and mechanism for delivering the tubular cover or sheath in position to receive the boxes, and covering mechanism by which the box is removed from the carrier and inclosed within the cover. With these mechanisms there is preferably combined a sealing mechanism by which a sealing-strip is applied tothe covered box, so as to secure the box-within the cover.

' The box-forming mechanism will tirst be described. The boxes may be formed from blanks held in a magazine, in which case the box-forming mechanism will consist simply of means for delivering a blank from the magazine to the holder on the carrier and a die for forming the box in the holder. In the preferred construction, however, which will now be described, the boxes are formed in the machine from a web of card-board or thick paper, as usual in box-making machines.

Referring now especially to the main views and Figs. 5, 6, and 27 to 29, two co-operating cutting-rolls 28 are mounted at the rear of the machine on the frame C, by which the webX of box-paper is advanced and cut to form a series of box-blanks connected at their ends, as shown in Figs. 5 and 6. These cuttingrolls 28 are driven from the main drivingshaft Il by a chain 290 and sprocket-wheels, the rolls being geared together to secure their proper action. Above the rolls28 and geared therewith is a short shaft 29, carryingacrankarm 30, which is connected by a link 31 to a bar 32, reciprocating between guides 33 and provided with feeding-fingers 34. These feed-- ing-fingers 34 engage the strip of box-blanks X, as shown in Fig. 6, and advance them over a supporting-roll in table 35, the throw of the feeding-fingers 3i being equal to the length of a blank. The guide 33 above the bar 32 is constructed ofl spring metal, so as to yield and allow the fingers to be raised and pass over the sides of the blank as the fingers arewithdrawn and insure their contact with the rear edges of the blank for advancing the latter. The blanks X are successively advanced by the fingers 3ft to a position above the holder M on the carrier, which has then been brought into position opposite the mechanism just de scribed. The blank may be of sufficient length only to form the bottom and sides of the box, but, as shown, is extended on each end so as to form, also, a cover for the box, so that the latter is closed on all sides before being inserted into the tubular cover or sheath. As the blank reaches the proper position above the holder and the feeding-fingers are withdrawn to feed forward another blank the blank is depressed into the holder and the open box formed by the descent of the die 36, which is carried by a bar moving between guides 37 and actuated by a pitman 38 from an eccentric 39'on the main driving-shaft H. The die 36 carries aknife 40, by which the blank is severed from the blank-strip as the box is formed.

Fig. 27 shows the box-blank in position for the descent of the die, Fig. 28 the blank severed andthe box formed by the die, and Fig. 29 the position of the box in the holder when the die is withdrawn.

As will be seen by reference to Fig. 3, the filling mechanism by which the cigarettes are TOO IIO

delivered to and packed in the'box thus formed is located, relatively to the carrier,one step in advance of the box-forming mechanism, just described, and, the box having been formed, the carrier is advanced by the arm lO one step to the filling mechanism, which will now be described. y

Referring especially to the main views and Figs. 7 to ll and 30, the cigarette-magazine consists of a hopper N, mounted above the carrier and box-feeding mechanism, and from which the cigarettes are fed byabelt 42, forming the bottom of the hopper, and ou which the cigarettes rest, this belt being carried by pulleys 43, the pulleys 43 being driven by a chain 44 and sprocket-Wheels from the main driving-shaft H. To secure the proper feed of the cigarettes from the magazine and prevent clogging, a vibrating separator 45 is used, carried by a shaft 46, mounted iu the sides of the magazine and provided outside the magazine with a slotted'arm 47, which is engaged by a lever 4S, actuated in one direction by a ratchet-wheel 49, carried by the shaft of pulley 43 and returned to position by the spring 50, a quick vibrating action being thus secured, which effectually prevents clogging of the outlet from the magazine. A buifer 5l is also provided for the separator. The tension of the belt 42 is preferably made adjustable, as shown, by mounting the bearing of pulley 413 to slide upon the base ofthe magazine, so that it may be adjusted by the screw 52, and Scrapers 53 are provided for keeping the belt clean, thus securing its proper movement. From the belt 42 the cigarettes pass down an inclined raceway 54 to the packing mechanism, by which they are counted and packed in the box. The machine is adapted to pack ten cigarettes in a box, and the cigarettes are received from the raceway in a receivingchamber upon narrow plates 55, which support the cigarettes at their ends and forming a swinging bottom for the receiving-chamber, these plates being pivoted by studs l and held normally in position to support the cigarettes by coiled springs 2, which yield to allow the plates to be forced by the packer to the position shown in dotted lines in Fig. 9, and the cigarettes to be thus delivered to the box in the holder M. The plates 55 are of sufficient length to hold five cigarettes and form a oontinuation of the raceway, there being just space between the end of the raceway and the outer fixed frame, in which the plates 55 are mounted, to receive the tive cigarettes supported by the plates. Above the plates 55 is mounted a vertical reciprocating plunger 5G, carried by a rod 57, sliding in guide 5S, this plunger being actuated by a lever 59, having a pin-and-slot connection with the head of the plunger and provided with a bowl (i0, running in a cam-groove 6l in a cam G2, carried by the main driving-shaft HL The cam is formed with two cam-surfaces at opposite sides of the wheel,so as to actuate the plunger twice during the rotation of the shaft ILtwol-ayers of cigarettes being packed in each box, and, as will be seen from Fig. l0, the cams are constructed of dierent depths, so that the second throw of the plunger is less than the first by the thickness ot' a cigarette, the second layer of cigarettes thus being packed with just the pressure required. To secure the proper packing, the plunger 56 is also preterably made adjustable upon its shaft. 57, as shown. should make a quick return after delivering the cigarettes, and for this purpose a spring is provided by which the plunger is normally pressed upward, and the cam-groove 6l is so formed that the bowl G0 is released j ust as the plunger has reached its lowest point to permit the quick ret-urn of the plunger by the spring. The form of the filled box and its position in t-he holder are shown clearly in Figs. 8 and 30. From the filling mechanism the filled box is advanced by the carrier to the covering mechanism, which includes a magazine and means for delivering a tubular cover or sheath into position to receive the box and means whereby the latter is inserted endwise within it. As shown, the box-covering mechanism is three feeding steps in advance of the filling mechanism; but it will be understood' that this will depend upon the number of holders with which the carrier is provided. By the use of a large number of holders a large capacity is attained with a low speed of the carrier, and the time between filling and covering permits the examination of the lled boxes. The covering mechanism may be varied widely and the covers may be placed in the magazine and fed therefrom in tubular form; but to permit a large number of covers to be packed in the magazine the covers are preferably packed fiat in the magazine and mechanism is provided by which they are opened as they are brought into position to receive the boxes. This cover delivering and opening mechanism Will now be described. The covers Y are `packed fiat in a vertical magazine O, mounted at one side of the path of the box as it isdelivered from the carrier, and the bottom cover is fed from the magazine by a plunger (i3, which is carried by a slide 64, connected tothe link 23, through which it is actuated from lever 2l, previously described. The plunger 63 has a set-screw and slot connection 3 with the slide 64, so that its throw may be adjusted to deliver the cover accurately. By reciprocating plunger 63 the cover is delivered in flat form in front of a second plunger 65, which is carried by a slide 66, having a pin-and-slot conn action with thelever 26, previously described, this plunger 65 also having a set-screw and slot adjustable connection 3 with4 its slide 66, .as iu the case ofthe plunger 63. These two plungers 63 and G5 move at right angles to each other, the plunger 65 taking the fiat box from plunger 63 and advancing it into the path of' the filled box as the latter is moved from the carrier to the sealing mechanism. The plunger G5 also opens the cover by the following It is desirable that the plunger 5GV ICO IIO

with ends of sufficient length so that one is means: The outer side wall (37 of the raceway on which the filled box is advanced is provided opposite the plunger 65 with a swinging spring-pressed finger b, which is curved so as to guide the edge of the cover upward as it is pressed against it bythe plunger and tend to open the cover, and the side Wall 67 is provided, also, with an overhangin g flange 5, beneath which the top of the cover rests when fully opened. The inner side wall 68 of the raceway is inclined upwardly toward the raceway, and also has an overhanging fiange 6, beneath which the top of the cover rests when fully opened. The operation of the construction is shown clearly in Figs. 15 and 16, the cover being gradually opened by the pressure of the plunger, the spring-curved finger b yielding as the cover is advanced by the plunger, the incline on the underside of the wall 68 permitting the cover to open, and the cover being held in position when opened by the side walls 67 68v and their flanges 5 6. A central guide 69, carried on the outside Wall 67 above the cover, aids, also, in holding the cover in position; but this will not generally be found'necessary.

For removing the filled box from the carrier and pushing it endwise into the cover opened to receive it, as just described, the following means are provided: The plunger 70, by which the box is removed from the carrier, is carried by a slide 71, moving on a support 72 and connected by a link 73 to the arm 17, previously described. As pre- Viously stated, the box is preferably formed closed down to cover the filled box and the edge of the other end lapped down upon it, and it is necessary that these projecting ends should be closed down prior to or during the operation of inserting the filled box into the cover. For the purpose of turning down the rear overlapping end the plunger is constructed, as shown, with fingers a, arranged to engage the overlapping rear end above the box. The other end may be lapped down upon this by engagement with the top of the cover as thebox is inserted within it; but with inferior blanks it is desrable to use for this purpose and for the purpose of holding the cover the center guide 69, previously described, which is beveled or rounded at its inner end, as shown in Figs. 11i, 31, and 32, so that thev end of the box is lapped down thereby and the filled box fully closed before the box reaches the cover, as shown in Fig. 32, this construction aiding to securethe properinsertion of the box and cover. rlhe guides 74, by which the filled box is held in proper position to enter the cover, are made slightly narrower on the sides and top and bottom than the cover, so that the box is properly guided and will readily slip into the cover.

rlhe action of the plunger in removing the box from the carrier and inserting it in the cover is shown clearly in Figs. 3l and 32.

The filled andfcovered boxes may be delivered by plunger 70 as the completed product of the machine, as shown in Fig. 33'; but a sealing mechanism is preferablyT used, as above stated, which mechanism will now be described.

Referring especially to Figs. 3 and 17 to 20, a strip of paper Z, perforated at points distant from each other the length of the sealing-strip to be applied, is advanced by a feeding mechanism consisting of a roll 75, driven by beveled gears 76 from a shaft 77, operated from shaft G, and a spring-pressed roll 78, coacting with the feeding-roll 75. The shaft of feeding-roll carries a crank-disk 79, connected by a rod 8O with a crank-disk 81, carrying a spring-pressed pawl 82, which engages a ratchet 83, carried on the shaft of a pasteroll 84, mounted to rotate in a paste-fountain 85. The strip of sealing material Z is supported between the feeding-rolls 75 and pasteroll S4 by a guide 4, and the paste-roll is provided With a brakedisk 6, by which the pasteroll is stopped when not positively actuated. The paste-roll 84 is grooved to apply paste in two lines at the edges of the strips, and a spring 5, lying in the groove, supports the paper on the advance side of the paste-roll and prevents its being carried around the roll by adhesion. From the paste-roll 84: the strip is advanced by a feeding-finger 7, engaging the perforations in the strip. This finger 7 is carried by an arm 86 on slide 66, previously described, and the feeding-finger 7 is pivotally mounted on the arm and springpresscd, as shown, so as to be withdrawn from the perforations as it is moved backward and forced therein to engage and feedforward the strip as it is advanced. To prevent the strip being carried backward by the drag of the finger, a spring-holding finger 87 is provided, engaging the perforations, the rear end of this finger forming a guide 8, by which the strip is turned at right angles, so as to be fed forward to the boxes lying in a vertical plane. The feeding-finger 7, holding finger 87 and guide 8, engages the strip between the lines of paste, so that the free movement of the lingers and strip is secured. The pasting-roll S4: is preferably constructed and operated to rotateduringdess than the full feed of the strip by the fingers, so that during a small part of the feed the strip is dragged over the surface of the paste-roll, a tension upon the strip being thus secured, which insures its proper form. The leading end of the strip Z is carried by the feeding-finger 7 into the path of the filled and covered boxes as they are advanced in line by the plunger 70, and the feed is sufficient to provide a sealing-strip of such a length as to cover the end of the box and lap over upon cach side. As paste is applied the full length of the strip on the side next the box, it will be seen that the sealing-strip is pasted onthe end of the box and two sides, thus securing the box in the cover. A guide T is provided, having a IOC IIO

groove in which the strip Z is held in correct position while being fed forward, thus insuring the proper attachment of the sealing-st rip to the boxes. u

For the purpose of severing` the strip at the desired points and pressing the strip upon the box so as to secure it the following means are provided: Aknife SS is carried by a rock shaft 9, mounted in arms on the under side of the frame D, and is operated bv a crankarm thereon, having a pin connection with a slotted link 89, carried by an arm 90, secured to' and moved by the slide 64:, so that as the slide is actuated to carry the plunger into position to take a cover from the magazine the Vknife 1s actuated to sever the strip, and as the plunger reaches its inner position in delivering the covered box the knife is withdrawn. rlhe boxes having the severed sealing-strip attached to their forward ends are advanced by the plunger between two feeding-roils 91, mounted on vertical studs 92,`

mounted in frame D, these feeding-rolls being preferably faced with rubber or similar material to secure the proper feed. One of the rolls 91 is rotated intermittently bya disk 93 on its shaft, carrying a spring-pressed pawl 94, wh1ch is engaged by a friction-disk 95, mounted on the shaftand oscillated by the slide Get, to which it is connected by a link 90. The feeding-rolls 91 are thus actuated at proper times to delivera box as it is received from the line advanced by the plunger 70, and the speed of the rolls 91 is such as to remove the leading box from the path of the strip Z before the latter is advanced by the feeding mechanism.

The completed, covered, and sealed box is shown in Fig. 84.

The operation of the various mechanisms has already been fully described, and the general operation of the mechanism will be understood from a brief description of the com'- bined operation of the different mechanisms. The box-forming mechanism is constructed to form a box-blank from the web and feed forward a blank into position above the carrier at each step forward of the latter, and as each holder on the carrier is thus brought into position with a blank above it the boxforming die or plunger severs the blank and forms the open box within the former. At the same time the box in the holder next in advance is being filled with cigarettes by the filling mechanism and a filled box in the holder three steps in advance of the llin g mechanism is being removed from the carrier by the plunger 70 and forced into the cover which has been delivered from the cover-1n agazine to the raceway in front of the filled box bythe plungers 625 U5 and opened to receive the latter. A gummed sealing-strip Z has meanwhile been fed forward by the stripfeed ing mechanism and is now in the path of the filled boxes. As the filled box is inserted in the cover the line of covered boxes is advanced the length of one box by the plunger,

Vblank is-received in the recess above it.

and the leading box of the line is thus carried against the strip and then between the feedingrolls 9l,with the sealing-strip pasted to the end, the strip being severed by the knife 8S as the box and strip move forward. The filling-box, with the strip attached, is then advanced by feeding-rolls 91 at such a speed as to remove the box from the path of the sealing-strip before the latter is again advanced by the feeding mechanism. The various steps of box covering, filling, and delivering having been completed and the parts co-operating with the carrier returned to position for another operation, the carrier is advanced another step and the operation j ust described is repeated.

While the box-forming mechanism will preferably be constructed so as to form the box from thel web, the boxes maybe formed from previously-prepared blanks, as above stated. In Figs. 21 to 2G we have shown such a modification. The general construction of the machine is identical with that previously described, except that the sealing mechanism is omitted and a box-magazine P, holding the box-blanks, is mounted above the carrier in position to deliver a box-blank to a holderM one step in advance of the die or plunger 36, by which the box is formed in the holder, as previously described.

For the purpose of securing the taking of a single blank from the magazine by the holder M the following construction (shown in detail in Figs. 23 to 2(3) is preferably used. The magazine P is open at the bottom and the boxblanks X are supported therein by fingers 97 'Ico 98, mounted on and held slightly below the bottom of the magazine. These fingers are connected at but one end to the magazine and are free at the end in advance relatively to the movement'of the carrier, so that the box! blanks are free to be carried out from the fingers and beneath the magazine-walls. The finger 97 extends entirely across the bottom of the carrier, so as to provide a sufficient support for the blanks, while the finger 9S'need extend only to the edge of the holder, as shown in Figs. 23 and 2b', to insure the proper position of the edge of the blanks. The carrier is provided above each of the holders M with lips 99, forming a recess of the same width as the box-blanks and of sufficient depth to receive a single blank, these recesses being so formed that they are directly below theline of box-blanks in the magazine as the holder is in position beneath the latter, and the fingers 97 98 being set in grooves in. the carrier, so as to allow the blanks to rest therein with the bottom blank inside the recess.- As the carrier advances from vthe position shown in Figs. 23 to 26, therefore, the bottom blank is carried forward therewith, held in the recess formed by the lips 99, and as the next holder is brought into position the bottom The construction of the die 36 and its operation upon the box-blank thus received are the same llO as in the construction previously described, in which the blanks are formed from the web, except that the knife 40 is omitted, and the combined operation of the various mechanisms is the same as that previously described and need not be repeated.

It is evident that many modifications may be made in the machine shown as embodying Jthe invention, and it is not to be limited to the specific form of any of the mechanisms or devices shown, as other constructions of the same general character may be substituted therefor Without departing from the invention.

What We claim isl. rPhe combination, with a box-holder, of mechanism co-operating with said holder to form and deliver boxes thereto, a box-filling mechanism by which the boxes are filled, and a covering and delivering mechanism by which the filled boxes are delivered from the holder and inserted in tubular covers, substantially as described.
