1 Claim. (Cl. 93-36) and repeated pulling on the lid is likely to cause the end ange to fail, as by tearing at the corners. Such tears are minimized by reinforcing the corners, and it is accordingly an object of the invention to provide such reinforcement for shoe boxes. Among the other objects of the invention may be noted the provision of an improved reinforcing element and blank for forming shoe` box lids; the provision of an improved method of and apparatus for applying such reinforcing elements to blanks; and the provision of an improved blank for` making box lids.
In the last respect, a pasted type of lid has been gen-V erally used in the industry. Such lids have been made from rectangular blanks, which are scored to deue inner and outer side and end panels, andwhichare slit to form corner flaps at the ends of the side panels. In manufacture, the end rpanels are folded over the corner flaps and glued to one another. With the construction herein disclosed, a die-cut blank is employedk which may be formed into a lid without gluing, the arrangement being such that the side and end panels interlock with one another to retain the lid in proper shape.
yWhere reinforcement is desired, the invention contemplates the use of pressure-sensitive adhesive tabs,
which are punched from a tape supply. The apparatus may comprise four independent tape supply and punching devices arranged to simultaneously apply the tabs, one at each corner of the blank. Each device, as disclosed herein, comprises a toggle-actuated punch, a stripoff unit between the punch and the supply roll, and a scrap windup unit on the other side of the punch. The operation is coordinated so that the strip-off unit is actuated while the tape is held by the punch, the scrap windup unit then being actuated upon release of the punch to remove the slack.
Other features of the invention will be in part apparent from and in part pointed out in the following detail description taken in connection with the accompanying drawings, in which:
Fig. l is an oblique view of a shoe box illustrating how the corners of the lid are likely to be torn in use:
Fig. 2 is a plan View of a blank for making a reinforced box lid;
Fig. 3 is an oblique detail view illustrating the manner in which the blank of Fig. 1 is set up as a box lid;
Fig. 4 is a partial oblique view of certain apparatus for applying reinforcing tabs to the blank of Fig. 2;
Fig. 5 is a front' elevation of the t-ab applicator partially shown in Fig. 4, certain parts being shown in section;
' Fig. V6 is a side elevation of the apparatus shown in Fig. 5, a supply roll of tape being shown in section;
Fig.. 7 is a horizontal section taken generally on the line 7 7 of Fig. 5; y
Fig. 8 is a detail front elevation of certain scrap takeup mechanism, parts being broken away; and
Fig. 9 is a detail top plan view of the mechanism shown in Fig. 8.
Initially, it may be noted that the stock carried by a retail shoe store is closely packed on shelves, and that the lid of a box is commonly employed as a handle for withdrawing individual boxes. Such manipulation of the shoe box B, as shown in Fig. 1, tends to subject the corner portions of the lid L to tearing forces. Al-
though various solutions to this problem have been proposed, the modifications suggested have generally tended to be expensive.
Referring now to Fig. 2 of the drawings, a blank of paperboard or the like is longitudinally scored at 1 and transversely scored at 3 to define a central cover panelv 2 with side panels 5 and end panels 7 hinged thereto.v
The side and end panels, in turn, are scored at 9 and 11, respectively, to dene marginal sections 13 and 15,
" respectively, for forming theinner walls. of the lid.
Both the side sections 13 and the end sections 15 are slightly shorter than the adjacentrside panels 5 and end panels 7. Also, the blank4 is cut at its corners in order to form llaps 17 and 19, the former extending endwise at a transverse fold line 18 from the side panels S and the latter extending endwise at a fold 20 from the side sections 13. v
Heretofore, such corner ilaps as those shown at 17 and 19 have been formed merely by slitting a rectangular Vblank along the lines of scoring 1 land 9 inwardly to the score 3; but in the'box of this invention, the ilaps are of a particular die-cut shape. It will be noted that the flap 17 is relatively wide, whereas the flap 19 is relatively narrow (half the width of the .wall part 13), thereby permitting the blank to be set up as a folding box as distinguished fromk a pasted box.
' In being set up, the wall sections 13 are folded over upon panels 5 and the latter are swung up at right angles to the cover panel 2. The corner aps 19 and 17 are then folded inwardly and the end panels 7 are swung up against the large corner aps 17. The box is completed by swinging the other wall sections 15 down over the corner flaps .19,l whereupon the inner. sections 13 and 15 become locked at their ends betweenV maintain the other panels 5 and 7 at right angles to the central cover panel 2.
Although the above-described construction is satisfactory for many purposes, a preferred embodiment of the; invention contemplates the use of reinforcing tabs 31 to,
prevent tearing of the corner flaps 17 and 19. These tabs are formed of some material, such as plastic, which hasv greater resistance to tearing than paperboard, and should be adhesively secured at each corner of the blank over, fold 18. strong and inexpensive, but is readily adapted for use with conventional high-speed blank-forming machinery This tab type of reinforcement is Vnot only when the tabs are punched from tape coated with pressure-sensitive adhesive.
Referring now to Pigs. 4-9, there is shown a device for punching and applying reinforcing tabs to the blanks. Although only onesuchdevice is shown forpurposesof simplicity, a preferred arrangement would include four ta-b applicators, .each .positionedftoapplya tab at a different corner of a'blank,` in conjunction with a blank feeder for intermittentlyfee'diiig blanks from the .diecutting and scoring machine beneath the. tab applicators.
Each device includes -a supply roll "R of pressuresensitive adhesive tape, a. punch P, and means for guiding the tape T lunder Ythe punch. The remaining scrap is then wound up upon a scrap roll S. In operation, the punch P is intermittently operated to cut a tab from the tape and apply the tab directly to a blank. A fresh section of tape is then fed to thepunch while a new blank is moved into position to receive tabs.
Although pressure-sensitive adhesive tape is preferred, it presents a problem of withdrawal. It may be noted that a circular tab is employed, this shape being found to be most satisfactory for die-punching operations. The resulting scrap must be disposed of but is -too weak to overcome the tension of the adhesive at the supply roll and permit withdrawal by drive at the scrap roll S. In the apparatus disclosed, a strip-off element operates on the strong, unpunched portion of tape extending from the supply roll R to the punch, while a take-up element D on the other side of the punch removes the slack created by the strip-off element O. These two elements are operated alternately in timed relationship with the punch so as to feed the tape at a proper rate.
More particularly, there is shown a generally vertical support 101, the lower end of which carries a bracket 103. This bracket in-turn has a lower horizontal slot 105 through which the tape T is guided by idler rollers 107, the latter being rotatably mounted upon the support 101. A reciprocating cylindric die 109 is carried by the bracket 103 within guide sleeves 111, and an openended cylinder 113 may be provided at the lower end of the punch in order to form a lubricant chamber. The lubrication of the punching die 109 tends to prevent difficulties that otherwise might result from adhesive collecting on its end.
The punch is actuated by a toggle system 115 having an arm 117 connected to the upper end of the die 109 and an arm 119 connected to a bracket 121. The center or knee 123 of the toggle is driven by a double-acting hydraulic or pneumatic unit 125. This unit is pivotally supported at its rear end upon a bracket 126 with the piston rod 128 thereof extending through an opening 130 in the support 101. It will thus be apparent that the die is actuated on both advance and retraction of the piston rod, thereby permitting a rapid punching rate. The die is extended its maximum amount as the toggle swings through center, and is retracted clear of the tape when the knee 123 is either in a retracted or advanced position. When the die 109 is advanced, its end 132 passes through a die port 134 to cut the tab from the tape and to apply same to an underlying blank. (See dotted lines of Fig. 5.) The bracket 121 may be made adjustable in `order to correlate the extended position of the die with the blank therebeneath.
The strip-off element is a roller 127 journaled upo-n an arm 129, the arm being pivoted at 131 on the support and being driven by a crank rod 133. The crank rod, in turn, is coupled to a crank plate 135 which is driven about an axis 136 by a spring-returned single-action hydraulic or pneumatic unit 137. In operation, the two power units 125 and 137 are preferably energized at about the same time so that the tape is held by the punch while an additional amount is pulled from the supply roll, the strip-off element 127 being moved outwardly upon energization of the hydraulic unit 137. The slack createdupon return of the strip-oft element 127 is then y the crank plate through a Vunidirectional drive.
taken up by the scrap drive on the other side of the punch, such take-up occurring after retraction of the punch and release of the tape.
The slack take-up element as herein disclosed is a knurled or serrated drum 139 rotatably mounted on the axis 136 over the crank plate 135, scrap being wound up upon the scrap roll S, which is biased against the drive drum 139. In order to provide for the increase in diameter as scrap Vbuilds up, the scrap roll S is carried by an arm 141, which pivotally mounted at 143 on the frame and gravity biased by a weight 145.
The drive mechanism for drum 139 includes a ratchet wheel 147 xed on the rear side thereof and coupledto A xed pawl 149 prevents counterclockwise rotation of the ratchet wheel, which is driven in a clockwise direction by a second pawl 151. This second pawl 151 is relatively movable with respect to both the ratchet wheel 147 and the crank plate 135 and may be mounted, for example, uponv a `bearing ysleeve 153 interposed between the, plate 135 and the wheel 147. A dog 155 carried on the end of the pawl `151 extends rearwardly beyond an edge 157 of the plate 135 (soas to be actuated thereby in a counterclockwiseV direction) and forwardly over the ratchet wheel 147 (so as to actuate the wheel in a clockwise direction). A spring 159 is secured at one end to the pawl 151 and at its other endl to the crank plate 135 to bias the pawl in a clockwise direction upon return of the plate.
When the hydraulic unit 137 is energized to rotate the plate 135 and actuate the strip-off device, the dog 155 is carried over the teeth of the ratchet wheel. Upon release of the pressure in the hydraulic unit 137, the crank plate is returned and the dog seats within one of the notches of the ratchet wheel, which is then biased clockwise by the spring 159. As the punch retracts clear of the tape, this spring 159 moves the drum 139 a predetermined amount suicient to take up the slack and feed a new section of tape beneath the punch. It will be understood, of course, that the amount of tape withdrawn by the stripoff` device O and taken up by the scrap drive D corresponds approximately to the width of the tab to be punched. l In order to prevent overrunning at the supply roll R, a spring 161 may be interposed between the hub 163 of the roll and the fixed support 101 so as to provide braking action.
For maximum speed, the strip-off operation should begin simultaneously with-the engagement of the tape by the punch. The strip-olf element should then retract on or preferably before completion of the punching operation so that the scrap roll will take up the slack immediately upon retraction of the punch, thereby preparing the tape for the next punching operation as a new blank is moved forward. In the case of a pneumatic or hydraulic type of apparatus, control valves would be ernployed for this purpose, such valves being known in the art and hence not described herein. The scoring and die-cutting apparatus and the blank-feeding apparatus may also be of conventional design. Although the movement of the blanks beneath the tab applicators should be coordinated with the operation of the punches in order to insure accurate placement of the tabs, various methods of producing such coordination are well known in the art. For example, the solenoid valves may be controlled by a microswitch positioned in the path of the blanks so as to be triggered as blanks are successively moved beneath the tab-applying apparatus.
From the above, it will be apparent that the reinforced blank herein disclosed is readily manufactured with minimum waste of reinforcing material. Although the tab-applying apparatus is disclosed in detail, many variations thereof will present themselves to those skilled in the art. For example, the means for guiding the tape under the punch is shown to be a pair of rollers, but they might be replaced with relatively xed guides if it is desired to reduce the tension developed in the weakened portions of the tape by the strip-oi device. Although one embodiment has been disclosed, it is to be understood that the invention is not limited thereto but the drawings and descriptions thereof are to be understood as being merely illustrative.
Having thus described the invention, what is claimed and desired to be secured by Letters Patent is:
The method of reinforcing a folding box blank along a fold line thereof, which comprises providing a roll of reinforcing tape coated on the surface thereof with pressure-sensitive adhesive, withdrawing a portion of said tape from said roll, placing a box blank opposite the coated surface of the tape with the fold line to be reinforced disposed opposite the tape, punching a tab of the width slightly less than the width of the tape from said tape directing onto the box blank, pushing upon the uncoated surface of the tape at a point between said roll and said punched portion while the tape is held during the punching step so as to strip olf another portion of the tape from said roll, thereafter releasing the punched portion and taking up the scrap to position an unpunched portion of the tape opposite the punching position.
