SAMUEI: BERGSTEIN AND ARTHUR C. E. LINDNEB, OF MIDDLETOWN, OHIQ, ASSIGNORS TO THE INTERSTATE FOLDING BOX COMPANY, OF MIDDLETOWN, OHIO- MACHINE AND METHOD FOR MAKING PAPER, BOXES.

Application filed October 17, 1925. Serial No. 63,140.

This invention relates to amachine and method for making paper boxes. i

The main object attained in the Invention consists in an automatic, or semi-au- .5 tomatic machinaadapted to makepaper boxes, the adhesive element for forming the joints of the boxes consisting 1n adhesive tape. and more particuiarly in the form of the invention here-in shown and described, I" tape having adhesive on both sides, hereinafter referred to as double faced adhesive tape. A

Recent experimentation and limited commercial practice has proved that adheslve tape is superior to ordinary adhesives, as glue, cement, etc., for forming the oints of paper boxes, particularly of boxes pro duced in large quantities by automatic machinery, the adhesive as'appli'ed to the tape being more uniform, more responsive to moisture and quicker to effect adhesion than ordinary glue, or cements; also the tape is less troubfesome, being cleaner and a self contained adhesive, as applied by the box making machines. and likewise cleaner and in all respects more satisfactory for boxes delivered knocked-down and set-up by the user. I

The improved machine, as herein set forth, is adapted for large quantity production and to be operated by the unskilled, except as .to acquired skill in facilitating production.

The machine is adaptable for producing boxes of Widely diversified character in size and design and to produce the uniformity of construction which is essential to a first quality product of this character.

In the accompanying drawings the improved machine is shown in a form-which illustrates the practice of the invention as used in making a common rectangular shaped box, it being understood that both the machine and the method of making boxes on the machine readily lend themselves to suitabe modifications to adapt the I practice of the invention to general paper box making.

Figs. 24 and 25 are detail views of the box ejector mechanism.

The improved box making apparatus as here shown comprises three main functions, i. e., the function of positioning a box blank on the, machine preliminary to the sealing operation, the function of applying strips of adhesive tape to certain of the portions of the box which are to be joined together, and the function of forming the joints, all operations of the machine being-directly or indirectly coordinated to this accomplishment.

r The machine as bost'shown in Figs. 1 and 2 is supported on a frame structure comprising an open base 100 and a hollow column 101 extended upwardly from the Rotatably mounted on column 101 is a work carrier 102 having a plurality, as here shown, of box supporting bases 103, the carrier is driven by a motor 104 and has an intermittent movement, with three stops to each complete rotation of the carrier. The driving connections between the motor and carrier consist of a shaft 105, flexible coupling 106, worm gears 107108, divided shafts 109110, clutch 111, segment gear 112, bevel gear 113, shaft 114, spur gear and ring gear 116,the latter being secured in the lower portion of carrier 102, the segment gear 112 having the required relation with gear 113 to actuate the carrier a third turn upoh each rotation of gear'112. In normal operation of the machine the driving relation between the motor and gear 112 is continuous. To stop movement of the carrier the driving connection is broken by shifting clutch 111 by means of the usual clutch connection yoke 117, shifter shaft 118, foot lever 119, yoke connected to shaft 118 as indicated at 121, a spring tensioned latch 122 serving to hold lever 119 when the clutch is disengaged. Upon releasing of the latch a spring 123 acts to raise the lever and thus to move the clutch into driving relation.

Stop mechanism for controlling the movement of carrier 102, as best shown in Fig. 3, comprises a cam 124 secured to shaft 110 or to gear 112, a cam follower 125 securedto the end of a rod 126 connected to a lex'er 127 pivoted in a bracket 128 and having its opposite end in engagement with a spring tensioned plunger 129, operable in a sleeve 130, a spring 131 acting to exert upward pres sure on the plunger and thus to cause the follower 125 to be at all times in contact with cam 124. The cam is timed with the movement of carrier 102 so that the cam follower will traverse portions a and b of the of plunger 129, to overcome the momentum of the carrier after gear 112 has passed out of driving engagement with gear 113. As the cam follower traverses portion 7) of the cam, stop 133 will be lowered sufliciently to engage stop 132, stop 133 being cut away on one side as indicated in Fig.2 to permit the stop to move into register with stop 132. A spring 134 followed by the downward movement of lever 127 as the cam follower ascends to portion 0 of the cam acts to press stop 133, which is hollow at its lower end,

down over stop 132 as the stops are brought to register one with the other, thus acting hesive tape and forming the box joints are also imparted to the several mechanisms from the clutch-controlled shafts 109110 by means comprising miter gears 135, shaft 136, miter gears 137 and a cam shaft 138 these parts being best shown in Fig. 2.

As best shown in Fig. 7 a series of three cams 139, 140, and 141 are secured to shaft 138, these cams and their coacting mechanisms being further illustrated in detail Figs. 8, .9, 10 and 11. ,Operating movement for the tape feeding and tape severing mechanisms is transmitted from cam 139, the connection to the former consisting of a pitman 142 connected at its lower end to the cam disc as best shown in Fig. 7 and at its upper end to a shaft 143 by a pawl and ratchet 144, a gear 145 being supported on the op posite end of the shaft. Gear 145 meshes with a gear 146 on shaft 147 and gear 146 with a gear 148 on shaft 149, opposite sets of tape, feed rollers 150 and 151 being supported respectively on shafts 147-149 as shown in Figs. 14 and 16. The upper feed rollers 151 are preferably knurled metal rollers, the lower rollers 150 being made of any suitable yieldable material, as rubber. Gears 152 and 153 supported on shafts 147-149 near their opposite ends serve to transmit the feeding movement through intermediate gears 154 and 155 and gears 156157 supported on shafts 158159 to feed rollers 160-161 forward of feed rollers 150151. Upper feed rollers160 are preferably made of yieldable material as rubber, the lower rollers being made of'a suitable material to which moisture adheres readily, the lower roller acting in its feeding relation with the upper roller to apply to moisture to the under side of the tape as the 'same is fed forward between rollers, the

moisture being carriedup by the roller from a pan 162 in which the roller is partially submerged.

The adhesive tape which as here shown is applied to the boxes in two opposite strips 163 is supported on the machine on spools 164 and delivered to .and through the tape feeding mechanism through opposite guides 165', the guides having suitable apertures formed therein adjacent thetape feeding rollers to permit the rollers to engage the tape.

It has been found desirable in the practice of the invention to move upper rollers 160 out of pressure contact with the tape and lower rollers 161 when the machine stands at rest to prevent the moistened face of the tape adhering to the lower rollers as the adhesive dries or sets. To this end the upper rollers and the tape guides'165 are supported in a separate frame 166 )ivoted on shaft 149 and adapted to be rocked on the shaft by means of a flexible cable 167 anchored at its upper end to a plate 168 supill) ;' is moved to the position illustrated in Fig.

2. to raise the forward end of frame 166,

upwardly extended frame 192 of the head base frame 193 which is supported on an intermediate column 191 which in turn is supported on main column 101. Shaft 191 is operatively connected, as best shown in Fig. 11, to cam 110 by means of a cam rollers 156 and tapes 163 out of engagement riser 195-supported on the free end of a with lower rollers 157, the parts being restored to normal relation upon releasing of lever 119 bysuitable spring tension.

The tape serving mechanism consists as best shown in Fig. 23, of opposite reciproeating blades 170 pivoted as indicated at 171 and connected by links 17 2--17 3 to a pivoted arm 174, the links 173 being connected on opposite sides of the pivot center 175 of arm 174 thus causing the severing blades to be actuated in unison, the blades being adjustable relative to each other by means of split bearings 178. Arm 174, as here shown, is adapted to be actuated in one direction on the cutting movement of blades 170 by a chain 176 and in the return direction by a spring 177. Chain 176 is connected at its opposite end to a ivoted arm 179, which in turn is connect to a pivoted arm 180 adapted to be actuated by a cam riser 139 of cam 139.

As the tape is drawn forward from the supply spools'the free ends enter a reciproeating extension 181, best shown in Figs. 14, 15 and*16, of tape guides 165, the severed portions of the tape lying free within the guides 181 as the guides, which operate as a shuttle, are moved'over the paper box supported on one of the bases 103, as illustrated in Fig. 5, the shuttle guides 181 being open on their upper and lower sides, longitudinally of the guides, as illustrated in detail Fig. 21 to ermit of the strips of tape supported therein to be pressed down ward and applied to the box as will presently be described. The shuttle guides are supported on a horizontally reciprocating shaft 182, best shown in detail Fig. 10, which is actuated from cam 141 through a cam 'follower 183. a pivoted arm 184, pivoted arms 185186 which are adjustable angularly one relative to the other by means of a split sleeve 187 to regulate the extent, of movement. imparted to the shuttle.

,The means for delivering the tape from the shuttle guides 181 and applying the same to the box, as best shown in Figs. 1, 5 and 22, consist of a vertically reciprocating pressure head comprising opposite yieldable pads '188 adapted to pass through the longitudinally extended apertures of the shuttle guides 181, thus acting to release the strips of tape supported therein and press the same uponthe adjacent surface of the paper box.

Pads 188 are supported on a plate 189 by v any'suitablei means, as byscrews 190, the

plate being supported on a vertically extended shaft 191 slidably support/ed in'an pivoted arm 1% connected by a link 197 to a pivoted arm 198 which in turn is connected by across shaft 199 to a second arm 198. connected by a link 200 to an arm 201, the opposite end of which is secured to shaft 202 extended transversely in the head frame 192 and which has secured thereto an arm 203"op eratively connected to "shaft 191 by a bifurcated end and spaced collars 204, arm 203 having a,rearwardly extended end 205 to which a spring 206 is connected which acts to return, the pressure head to raised position following each downward reciprocatio thereof. v

The three positions of stops of the work carrier are best illustrated in the plan view of the machine in Fig. 4 by the reference characters A, B, and G. In the position A the box blanks are positioned manually, as here shown, on the supporting bases 103, the bases having opposite side retaining clips 207 which act to support the blanks by exerting pressure thereon, the sides of the box being pressed a ainst the sides of the base, the opposite sicre end sealing flaps a being folded by hand and their inner edges inserted under; a retaining clip 208. The stops of the work carrier are of sufficientduration to permit of removing a box from its supporting base, the base then in position A, and inverting the box end for end or applying another blank thereon, it being understood that the machine as here shown is adapted to form one end of the box only in a single sequence of operations applying mechanism. As the work is moved from position B to position C the end of t-he box having the outer faces of the tape exposed thereon is moved under a series of guides 209 which act to press the ta )e more firmly to the sealing flaps as the en of the box moves into engagement with a second tape moistening device 210, best shown in detail Fig.- 12, consisting of a web 211 "construeted 0 suitable material to absorb moisture, the web being operableover a series of rollers 212,213, 214, 215, 21c and 217, roller 212 actuated by means of a pawl 218 and ratcl'iet'219, being the driver for the web. Operation of the pawl and ratchet is effected" by a lever 220 having its free end extended into the path of and actuated by lugs 223 supported on carrier 102, a spring 221 acting to return the leverfl to normal ptosition following each actuation thereof. oller 212 is partially submerged in water in a container 222, thus causing the web 211 to become saturated as it passes under the roller, the distributing rollers 213, 214, 215 acting to evenly impregnate the web with the moisture before the web passes under roller 216 and comes in contact with the ends of the boxes as the same pass thereunder, the exposed. faces of the tape being moistened and rendered adhesive as the same are brushed over the face of the web. a As the boxes, supported on bases 103 approach position C the scaling flaps b which are still in extended post-ion are engaged by a guide 224 which acts to fold the flaps over flaps a, in posit-ion to complete thesealing operation under pressure in position U. the means consisting of a pressure head 225 supported on a vertical shaft 129 and actu- 4 ated in the upward d'rection by the spring 131, as previously described and best illustrated in Fig. 3, the downward movement of the pressure head being effected by cam.

124 as the cam follower rises to portion 0 of the cam.

As best illustrated in Fig. 1 and detail Figs. 24-25 box ejector or kick-ofi' mechanism is provided on each of the box carrying units 103 which acts to remove the box as the carrying member moves from position G to A. The means employed consist of a cam 226 secured to column 101 as illustrated in Figs. 6 and 24, a lever 227 pivoted on the carrier housmg 102 as at 229 having a cam follower 228 at its lower end adapted to engage cam 226 thus to reciprocate the lever,

the upper end of the lever being connected pivotally as at 230 to parts 231 mounted slidably on opposite sides' of the supporting bases 103. The position of levers 227 is normally substantially vertical, until the same are moved into engagement. with cam 226,

when the lower end of the lever is moved inward as illustratedin Fig. 24 and an outward movement is given to the members 231 which engage the box and kick it off the supports 103, it being understood that double end boxes are again replaced on the supporting heads after the first removal thereof thus to complete the construction of both ends of the box. A spring 232 acts to return the kick-off mechanism to normal following each operation.' The leek-off members 231 contact on their inner faces-with a series of pins 233 set in the base of box supports 103, the outer face of parts 231 being free,

'the same being kept in alignment by the tension exert-ed thereon by springs 232.
