APPARATUS FOR APPLYING TAPE Filed Aug. 30, 1965 Sheet 5 United States Patent 9 Claims This invention relates to improved apparatus for feeding and cutting a predetermined length of tape and applying the cut length along a piece of work. The apparatus is especially designed to apply strips of tape along the seam of flat tubular box blanks which are advancing individually and successively along a path.

In folding paper box machinery, the fiat box blanks are conventionally fed individually from a stack of blanks along a horizontal path through the folding machine, the outer panels being overfolded over the inner panels, and the free adjacent edges of the overfolded panels are joined by glue, hot melt adhesives, staples, tape, or the like, to form a flat tubular box. Machines for the purpose are well known, and the machine illustrated herein is the L B machine made by International Paper Box Machine Company of Nashua, N.H., and shown and described in detail in the following United States patents: No. 2,912,239, Nov. 10, 1959, to La Bombard; No. 2,949,066, Aug. 16, 1960, to La Bombard; No. 2,915,950, .Dec. 8, 1959, to La Bombard; :No. 3,039,372, June 19, 1962, to La Bombard; No. 2,931,277, Apr. 5, 1960, to La Bombard.

There are so many taping devices, or heads, in the prior art which are usually mounted at the end of the folding zone in the folding machine, in advance of the squaring up or stacking zones, but :known devices have disadvantages especially when the machine is operated at the high speeds demanded by the trade. For example, some taping heads apply the tape to the box, and the advancing box pulls on the tape with possibility of tape fracture, some feed the tape intermittently with a repeated opening and closing of the tape feed nip rolls, and, in most of the tapin-g heads of which -I am aware, the cutter knife forms a temporary barrier to the advance of the tape while approaching toward, cutting, and retracting from the tape.

In this invention, the above disadvantages are avoided, and accuracte, high speed, application of correct lengths of tape accomplished, by continuously rotating a large diameter tape applicator roll at the speed of the blanks, continuously feeding the tape toward the applicator roll at a lesser predetermined speed, and automatically cutting the fed tape, in advance of the applicator roll, at predetermined intervals. For a particular run of identical blanks, the taping head is adjusted to cut the fed tape to a length exactly equal to the length of the blank seam and to feed the tape at the required speed, so that the cut strip will be drawn away from the uncut tape by the applicator roll and applied on the blanks with no back pull on the tape and with exact registration on each successive blank. Since the tape is continuously advancing toward the more rapidly rotating applicator roll at a predetermined lesser speed, the cutting knife is arranged to advance with the tape at a speed equal to that of the fed tape while cutting off the strip, and then to retract outside the path of the tape, by riding on the top face without offering any resistance to advance of the tape.

The principal, object of the invention therefore, is to provide a taping head which accurately applies a cut length of tape to blanks advancing individually and successively along a path, with no back pull on the tape and with no piling up of the tape at the cutting knife.

3,421,963 Patented Jan. 14, 1969 Another object of the invention is to provide tape applicator means in the form of a single large diameter roll, capable of carrying the full length of a cut strip of tape and applying the strip to each blank exactly on the blank seam.

A further object of the invention is to provide a novel movable cutting knife in a taping head, the knife blade being tiltable to exert a cut against an anvil roll on its forward stroke, but to move its tip out of the feed path to ride on the advancing tape on its rearward, or retraction, stroke.

Still another object of the invention is to provide a large diameter tape applicator roll serving as a combined article-feed, tape-carrier, and tape-applicator roll, there being spaced hold-down rolls for retaining a cut strip on the circumferential face of the roll and a moistening device mounted close to the tape application area of the face to assure that the tape is still moist when applied.

A still further object of the invention is to provide such an applicator roll with a groove, and to provide an end less pressure and stripper belt in the groove, the belt and groove being on one side only to press the tape into firm adherence along one edge of the seam while leaving the other side free to slide during the subsequent squaring up of the box.

Other advantages and objects of the invention will be apparent from the claims, the description of the drawings and from the drawings in which:

FIGURE 1 is a plan view of the apparatus of the invention, showing parts of the folding zone and squaring up zone of a typical paper box folding machine;

FIGURE 2 is a side elevation of the apparatus shown in FIGURE 1, in section on line 2--2 of FIGURE 1;

FIGURE 3 is a side elevation, similar to FIGURE 2, but from the opposite side of the machine, showing the drive trains;

FIGURE 4 is an enlarged fragmentary side elevation, from the same side of the machine as shown in FIGURE 2, showing the cutter means with the blade at the forward end of its forward cutting stroke and showing the tape feed nip closed and the cutter in operation;

FIGURE 5 is a view similar to FIGURE 4, showing the cutter blade near the rearward end of its retraction stroke, and showing the tape feed nip open and the cutter out of operation;

FIGURE 6 is a still further enlarged fragmentary view showing the cutter blade in various tilt positions; and

FIGURE 7 is a circuit diagram.

As shown in FIGURES 1, 2, and 3, the machine 24 is a typical paper box folding machine, which normally includes a blank feed zone, a folding zone, a gluein-g zone, a squaring up zone, and a stacking zone. Only the end of the panel overfolding zone 25, is illustrated, the lower carrier belts 26, driven pulleys 27, and driven shaft 28, advancing the fiat articles 29 along the path, or paper line, 31, in the direction of the arrows. The driven shaft 32 carries folder belt pulleys 33 and 34 for folder belts 35 and 36, the folder belts, lower carrier belts and upper carrier belts (not shown) all being synchronized and driven in a Well known manner, shown and described especially in the above mentioned Patent No. 2,931,277. The flat articles, in the embodiment illustrated in that patent, and herein, are flat, tubular paper box blanks 37, the outer panels 38 and 39 having been overfolded inwardly to overlie the inner panels 41 and 42, and to bring their respective outer edges 43 and 4 4 into abutting relation to form a seam 45. At the end of the folding zone 25, the article advancing means 46 includes the lower carrier belts which support the flat blanks plus the frictional contact, on the upper faces '47, of the upper folder belts, but, as explained in the above patent, No. 2,931,277, these belt speeds may not be the same because variation of belt speed is useful in combatting the effect of air resistance on the panels during overfolcling. The taping zone of machine 24 is designated 19.

The taping head 50, of this invention, includes a combined article, or blank, feed, tape-carrier and tape-applying roll 51, mounted to rotate on bearings 52, carried by the driven folder belt pulley shaft 32. The roll 51 may thus be drivingly rotated with a surface speed exactly equal to the speed of advance of the blanks 37 on carrier belts 26, regardless of the speed of the folder belts. As best shown in FIGURE 3, roll 51 is driven with its circumferential face 53 travelling in the direction of advance of the blanks at the tape applying area 54, where face 53 engages the upper faces of the blanks, by gear 1 power train means consisting of gears 40, 55, 56, and 99, sprocket 99, chain 80, and sprocket 100, gears 57 and 58 to the Reeves-type variable speed unit 59, which also powers the shaft 28 of the lower carriers 26.

Taping head includes side frame pieces 61 and '62 mounted for lateral adjustment on a cross frame member 63, to permit the roll 51 to be aligned with the seams of blanks of various configurations.

Supported on the frame pieces 61 and 62 of taping head 50, are a plurality of hold-down rolls such as 64, preferably of Teflon, and each having a spring 65 for spring loading the roller with predetermined pressure against the circumferential face 53 of roll 51. The holddown rolls 64 are spaced circumferentially around face 53, to at least partially encircle the face and to extend from the tape receiving area 66 to the tape applying area 54. The final set of hold-down rolls 64, located close to paper line 31, are carried by one or more detachable members 67 mounted on the centre support 68 for the rolls.

Where the tape to be applied is of the gummed type, requiring moistening before application, the tape moistening means 70, consisting of a suitable water tank 71 with moistening roll 72, is preferably mounted close to the paper line 31, as shown in dotted lines in FIGURE 2, to assure that the applied tape is moist and has not dried out. The means may also be mounted on a frame cross bar 73, as shown in full lines in FIGURE 2, in which case the members 67 and rolls 64, occupy the preferred position of the tank 71, to hold the tape strip on the roll 51 until it is applied to the blanks.

The tape feeding means 75 of the invention includes a suitable tape source, such as the supply roll 76, containing a continuous tape 77 of any desired type, journalled to freely rotate on a shaft 78 carried by frame posts, such as 79. The tape 77 is guided through a suitable slack take-up device not shown, or torsion brake means 81 may be applied to the exterior of the roll for slack take-up purposes, as shown, the tape passing through the tape feed nip 84 and the nip 85 to the tape receiving area 66 of the roll 51. Suitable guides, or idler rolls, 86 and 87, are provided to support the tape where necessary, the guide 87 directing the tape into tangential engagement with the face 53 of roll 51.

Tape feed nip 84, is formed by the driven roll 88, mounted on a shaft 89, and serving as a backer, or bed, roll opposed by the undriven tape feed roll 91. Tape feed roll 91 is mounted on eccentric bearings 92, so that it is adjustable to vary the pinch, or clearance, at the nip in accordance with the thickness of tape used. The bearings 92 are supported on a shaft 93, and the inner races 94 of the bearings are connected to an arm 95 having a spring 96 at the outer end thereof for normally spring loading the feed roll 91 into a closed nip relation. One, or both, of the tape rolls 88 or 91 may have a knurled face, such as 97, if desired.

The tape feed means 75 also includes a pair of rolls 101 and 102 forming the nip 85, roll 102 being driven and mounted on eccentric bearings 103, similar to bearings 92, for adjustment of nip clearance.

The tape feed roll means includes roll drive means 104, for driving the rolls 88 and 102, and for driving an anvil roll 105, at a predetermined lesser speed than the speed of advance of the blanks and the surface speed of the face 53 of roll 51. Drive means 104 is powered by the shaft 106 of variable speed drive 59 through knee action supported chains and sprockets 107, 108, 109, 110, and 111, sprocket 109 being journalled at the junction of pivoted links 113 and 114, so that the head 50 may be raised and lowered in accordance with blank thickness. Shaft 116, driven by sprocket 111, is connected by a train of gears 112 to rotate rolls 88, 102, and 105, and thereby advance the tape 77 along the feed path toward the face of roll 51.

Tape cutting means 115 includes the knife arm 121, best shown in FIGURE 6, the arm having a split clamp 117 mounted on the swing shaft 118 and having a cutter blade 119 with a cutting tip 120. The free end of arm 121 has angularly disposed faces 12 2 and 123 meeting at the apex line 124 for seating blade 119, there being a pin 125, slidable in a bracket 126, and pressing on the centre of the blade by reason of leaf spring 127. It will be seen that the blade 119 oscillates forwardly with the tape, and at the speed of travel of the tape, while supported by face 123 in a plane radial to shaft 118 until the tip 120 pinch cuts the tape at the point of tangency with the rotating anvil roll 105. The blade tip 120, and the tape 77 continue forwardly at the same speed, while the cut length 128 is drawn away more rapidly in a forward direction by the face 53 of roll 51, since the tape strip 128 is no longer restrained by connection to the tape supply. As shown in dotted lines, at the end of its forward stroke, tip 120 is lifted out of the tape path, whereupon arm 121 oscillates rearwardly on the return stroke with tip 120 riding on top of the continuously advancing tape. The friction, and forward travel, of the tape tilts the blade 119 so that its upper portion retracts into the recess formed by angular face 1 22, thereby permitting it to pass the tangent point without cutting. Spring 127 yields to permit the tilt, but restores the blade to its radial plane at the end of the rearward oscillatory stroke. The stroke of the knife is preferably about 22, or 11 on each side of the cutting nip 129.

The cam mechanism 132 oscillates the arm 121 at predetermined speed, as shown in FIGURES 4 and 5. The clutch shaft 133, connected to the power train 134 by the clutch 135, rotates unidirectionally to turn the eccentric earn 136 to thereby actuate the yoke crank arm 137. Arm 137 is pivoted at 133 to the link 139, the other end of link 139 being pivoted on the cutter arm swing shaft 118, but not drivingly connected thereto. Link 139 carries a cam 141 having an inner cam path 142 with a depression 143 and an outer cam path 144 with a pair of protuberances 145 and 146.

A bell crank pawl 147 is pivoted at 148 to cam 141, pawl 147 having a roller follower 149 at one end, which engages the inner cam path 142, and having the other end 151 arranged to engage a groove 152 in the cutter arm 121. It will be seen that in FIGURE 4 the end 151 of pawl 147 is engaged in groove 152, so that the knife arm 121 is oscillated forwardly to cut the tape, the follower 149 being within the depression 143. However, in FIGURE 5, when a signal has been received that there is no oncoming blank, the follower 149 is no longer in. the depression 143 and the end 151 of pawl 147 has been lifted out of groove 152 so that, while the clutch shaft continues to rotate, the pawl rides over the knife arm and does not cause it to oscillate and cut. The pawl 147 is returned by spring 153 and the cutter arm is returned by the spring 154 (FIGURE 3).

The machine of the invention, once set up to apply a particular length strip of tape on each of a plurality of identical fiat tubular boxes will continue to do so without adjustment for a complete run of boxes. However, in case of a misfeed in the feeding zone, there may be a space on the paper line not occupied by a box, and if a tape strip were supplied as usual, it would fail to be picked off the applicator roll and would interfere with subsequent strips. Therefore, automatic actuation means 156, is provided to open the tape feed nip and deactuate the cutter momentarily so long as one or more boxes are not sensed on the paper line.

Means 156 includes a pair of solenoids 157 and 158, oppositely disposed with a common armature 159, there being a member 160 pivoted to the machine at 162 and having one end pivoted at 163 to the armature 159. The other end 164 of member 160 includes a recess 165 in which a pin 166 on cam 141 is received. In FIGURE 4 the solenoids 157 and 158 are de-energized. The member 160 and pin 166 are to the right, pawl 147 is in groove 152, the roller follower 167 of arm 95 mounted on feed roll shaft 93 is in closed feed nip position and the bell crank detent 169 has its tip 170 in recess 165 to hold the parts in position.

In FIGURE the solenoid 158 has been energized to move the member 160 to the left, thereby moving pin 166 and cam 141 to the position shown. This causes pawl 147 to be lifted out of groove 152 to stop cutter action, and the protuberance 145 lifts follower 167 to open the tape feed nip to stop tape feeding action. The member 160 has lifted tip 170 of latching detent 169 out of recess 165 while the tip 172 of the oppositely disposed latching detent 173 has dropped into recess 165 to hold the parts in deactivated position. A spring 174 connects detents 169 and 173 to spring load the tips 170 and 172 toward recess 165.

Automatic actuation means 156 also includes a protuberance 176 on clutch shaft 133 which contacts the roller follower 177 of the armature 178 of a normally open switch 179, with each revolution of the clutch shaft to close a circuit. It also includes a normally closed switch 180 mounted at a predetermined spaced distance in advance of the taping zone 19 on the paper line, or path, 31, of the flat articles advancing along the path, the switch 180 having an armature 182 normally held down to close switch 180 by the individual successive articles traveling over the same, and a switch 181 normally open in the presence of a blank. So long as armature 182 is held down by the presence of advancing articles, it keeps open a circuit 183. However, in the absence of a blank on the paper line 31, due to misfeed, the armature 182 closes the switch 181. When protuberance 176 then rotates to a position which moves armature 178 to close switch 179, circuit 183 is closed. The closed, or non-feed circuit 183 then includes the source of current 184, conductor 185, the coil of solenoid 158, conductor 186, switch 181, armature 182, condnctor 187, armature 178, and conductor 188 back to the source 184. The energization of solenoid 158 shifts the device to the non-tape feed position of FIGURE 5.

When a blank is again present to actuate armature 182 to close switch 180 and open switch 181, the feed circuit 190 is closed, which includes source 184, conductor 185, conductor 191, the coil of solenoid 157, conductor 192, switch 180, armature 182, conductor 187, armature 178, conductor 188, back to source 184. The energization of solenoid 157 shifts the device to the tape feed position of FIGURE 4, so that it will feed tape to each blank or box when protuberance 176 closes switch 179.

As shown in FIGURE 1, each flat tubular box, whether the outer edges 43 and 44 are abutting or Overlapping, has a tape strip 128 of the exact length desired, adhered along both sides of the seam 45 as the box leaves the taping zone 19 to enter the squaring-up and stacking zone 191. The squaring-up of the box will be fruit-less if the tape 128 has adhered to the overfolded panels on both sides of the seam, since the box might yield for squaring and then return to its unsquared condition.

In this invention, combined tape stripper and tape pressure means 192 is therefore provided. Means 192 comprises an annular groove 193 in one side of the face 53 of the roll 51, an idler lroll 194 aligned with groove 193, and an endless belt 195 trained around the roll 194 and the groove 193. The belt 195 assures that each successive tape length 128 will be stripped from the face 53 while at the same time applying adherance pressure only to the side 196 of the tape overlying one side of the seam 45. The other side 197 of the tape strip 128 is thus not yet adhered as the box passes through the squaring-up mechanism 198 and the panels of the box may be still moved into squared-up condition by sliding with relation to said tape. Once squared up, the other, unadhered side 197 of the tape becomes adhered to the other side of the seam of the box under the pressure of stacking in the stacking zone.
