CARTON TAPING TOOL The present invention relates generally to a hand tool for applying, from a tool-carried supply roll, pressure sensitive tape for closing or sealing or wrapping cartons or similar packaging.

Carton taping hand tools or implements are known carrying a rotatably supported supply roll of pressure sensitive tape unwound and led over a tape guiding and applying roller; a tape cutter blade secured by a special clamp plate, and, for subsequently pressing the applied tape into adherence on a packaging surface, a special pressing roller; usually having associated with the applying roller a tape control element or roller to provide an anti-retraction device preventing the tape from pulling back toward the supply and thereby keeping it in position at the applying roller ready for use.

Such prior tools have labored under various disadvantages, such as complexity of construction, therefore attendant costs, where acceptable function is achieved, or have had undesirable characteristics of operation and/or durability. For example, in prior constructions, with the tape control anti-back up element nonrotatable and with the pressure sensitive side of the tape contacting that element, the element has to be mounted on a pivotal arm structure, which is tensionspring-biased toward, but (for threading the tape,) liftable from, the applying roller; and considerable effort is usually required for drawing the tape out of the tool, not only at the start of but also throughout the tapeapplying tool stroke.

Further, in prior tools of this type where the frame or body is comprised of metal stampings, castings or the like elements, with thin walls for lightness, and a tape roll supporting drum is supported in such a frame by a rotatable metal shaft, wear due to high bearing pressure between the rotating shaft and the small bearing surfaces in the thin frame walls develops a looseness in the shaft-supporting aperture or journal area. This shortens the effective tool life as well as causes undesirable performance, unless there are incorporated structural expedients relatively costly for the nature of the tool.

Also in prior constructions, often the tape roll supporting drum would not locate and maintain the roll in the frame in proper position relative to other operative parts, especially relative to the guiding and applying roller, thus frequently causing a tendency of the tape, as it is drawn from the supply roll, to distort by partial folding or transverse curling, leading to incorrect feed, so that the tapeis not applied smooth and flat to the article. Such improper performance results not only in a poor appearance of the finished packaging, but also in difficulty in the tape cutting by a severing blade of the tool. As a practical matter, considering the type of work being done and the speed to be expected, it is not without some difficulty that such folding or distortion of the tape can be overcome by drawing further tape from the supply roll, for once it has begun, it tends to propagate itself continuously as the tape is unwound.

By the present invention there is provided a package taping hand tool incorporating several improved featureswhich in their cooperative relationship'in the tool as a whole permit, for example, in a pistol grip type tool, a construction which is relatively simple both in the number of structural elements and in their mode of fabrication, consequently resulting in a low manufacturing cost while giving an improved tool service life andperformance, and overcoming or minimizing one or more of the aforedescrisbed disadvantages of prior tools of this type.

Thus, for example, by an improved and simple tape supply roll receiving drum assembly ensuring both an initial proper location of the tape roll and maintaining it so during use, also adapted readily to receive properly a supply roll of which the paste board spool may be somewhat out of round, an initial and continuing correct feed and elignment of the tape toward the pressing applying roller is facilitated.

Further by use of a drum shaft made of an appropriate plastic'material such as a polyacetal resin or a polyamide resin, e.g., Nylon, the shaft journalling or bearing arrangement in the frame may be reduced to a simple punched out opening with only initial slight operating clearance; since, upon initial tool use, a slight initial wear of such plastic from the shaft onto the surrounding bearing walls of the shaft receiving openings in the frame thereafter provides a smooth self-lubricated bearing contact, avoiding the fast wear which would otherwise arise between metal shafting and frame plates in such situation, unless a more expensive bearing structure is provided. End pilot means and axial contractability are further provided in the shaft to enable removal of a used tape spool and correct insertion of a new tape roll.

Furthermore by use of a rotatable tape end retaining anti-back up or control roller adjacent the tape pressing guiding and application roller, and with one or the other or both of these rollers including an overrunning clutch type device providing free forward rotation upon tape feed but locking against backward rotation, thus to keep the tape from backward withdrawal from the tape discharge end (with a simple eccentrically pivoting mounting permitting the control roller upon incipient tape retraction to press toward the pressing roller where the latter does not include such clutch), there is avoided the necessity of providing, in the frame, means for accommodating and mounting control roller actuating or biasing tension springs. A simple overrunning clutch device is provided, easily incorporated even in a small tape control roller assembly.

With these features, the basic frame or body of the tool may be provided by a pair of simple mirror image, that is right and left handrelated, metal stampings mounted therebetween the supply roll drum shaft and the pressing roller shaft; the plates being held together as a rigid frame through the mountings of a hand-grip, of a tape cutter blade and pressure finger, and of the tape pressing application roller. To this end, a pistol grip has integral interengaging end pins through opposed central bottom flanges of the plates, and the latter are further secured against the grip end by a lock washer and nut threaded on a stud insert molded in the grip end.

The frame plates thus are held as well at the central region in appropriate spaced parallel relation by integral pins of the plastic grip through flange apertures.

To the same purpose, at the forward or working end of the tool, in the tape guiding and pressing application roller mounting region, on the top side of the frame, away from the grip, the plates have a pair of respective opposed inward coplanar front flanges forming a knife support surface, to which also is mounted the base of an outwardly projecting, resilient tape presser plastic finger aptly located firmly to pressthe terminal or cutoff end of an applied tape, thus eliminating the prior art special roller for this purpose. The finger base is held by screws therethrough threaded into the respective front flanges; and serves not only to clamp the cutting blade in adjusted position but also as spacing reinforcement for the front end frame portion, while eliminating a separate knife blade clamping element.

The abovementioned aspects of the improved tool are hereinafter described in detail.

It is the general object of the present invention then to provide an improved hand tool for applying tape, particularly pressure sensitive tape, to cartons and other packaging. It is a further object of the invention to provide a tool of the character described having a durable but simplified low cost construction while reliably meeting practical needs. It is a still further object of the invention to provide a tool of the character described in which a tape control roller is rotatably mounted, and in which one or the other, or both of the control and the pressing rollers incorporate an antitape back up or withdrawal preventing means, permitting, however, free tape forward feed.

A still further object is to provide a tool of the character described having an improved supply roll supporting rotatable drum adapted to ensure initial and maintained correct positioning of the supply roll during use of the tool. Still a further object is to provide a supply roll supporting drum having an axle or shaft construction which is easily removed from and inserted in the frame, and which further is adapted to be used in simple punched-out shaft supporting or bearing openings in the frame. A further object is to provide a tool with a simplified construction including two mirror image stamped plates, the securement of which into a rigid frame is aided by cooperating mounting engagement thereof with a pistol grip and with a cutoff blade securing base of a tape pressing resilient finger element.

FIG. 11 is an axial longitudinal section of the drum of FIG. 10.

One embodiment of the taping hand tool of the invention, as shown in FIG. 1 of the drawings, is comprised of a frame 10 provided by two mirror-image right and left hand side plates 11, for example, aluminum stampings, extending in longitudinally parallel spaced relation to each other; the pistol hand grip 12; a removable rotatably mounted drum-like core or support 13 upon which is seated the pasteboard spool 15 of the adhesive tape supply role 14; a control roller 18; and rotatably mounted in the frame forward or working end, a tape pressing and guiding application roller 17 by which the tape strip 16, unwound adhesive side down from roll 14, is guided and pressed onto a carton to be sealed or other like packaging. The tape roll receiving drum structure 13 includes a shaft assembly 23 rotatable in apertures 24 providing shaft bearing in a bifurcated rear end structure of the frame.

One or both of the rollers 17 and 18, between which tape 16 is led, embody what may be called an overrunning clutch type device,as shown in FIGS. 2-3 for roller 18 hereinafter described; that is, the roller is freely rotatable in a forward direction allowing the tape 16 to feed outwardly thereover, but clutches or engages against reverse rotation thereby preventing rearward escape of the tape end 21 from between the rollers and thus maintaining it in position ready for the beginning of the next operation.

On inward opposed coplanar flanges 37 bent at right angles on the top front of the respective plates 11 above the pressing roller 17 (see detail FIG. 4), a tape cutting blade 19 is securely clamped by the base structure 20a of a tape-smoothing resilient pressing finger 20, (preferably made of a durable plastic), secured by the screws 39 passed therethrough and threaded into respective flanges 37.

The shaft 22 of roller 17 is supported in aligned apertures of the forward bifurcation-forming front ends of the side plates 11. With the ends of shaft 22 reduced in diameter to afford plate spacing shoulders and externally headed down on the side plates, and a spacer element or sleeve 29 having a rivetted side plate engagement as shown in FIG. 1 above the handle, there results a firm fastening of the frame elements to each other in the heavily stressed front and middle portions.

As shown in FIGS. 5-6, the pistol grip 12 is securely held and oriented on the opposed central bottom coplanar broad flange, portions 57, 57 inwardly bent on and at right angles to the respective frame walls 11. The grip flat top surface 54 has integrally molded upwardly projecting lugs or pins 55, 55a, 55b, 55c cooperatively engaged in respective corresponding rounded punched out flange apertures 56, 56a, 56b, 56c, and also an upwardly projecting molded-in threaded stud insert 59 extending between accommodating flange edge notches for grip clamping by a washer and clamping nut 60. This structure not only provides a rigid attachment for the molded plastic handle, but also, in cooperation with the previously described elements conduces to overall frame strength, as the frame plates are held centrally in rigidly spaced parallel relation.

Thus a simple rigid frame is provided, even with thin wall aluminum stampings for plates 11, the use of which is feasible by other features later described, including a particular shaft structure 23 for drum 13.

These plates 11 are readily fabricated, as stamped elements at low cost, to include the longitudinally extending stiffening ribs or grooves 30; the apertured flanges 37 and 57; and apertures for the tape application roller shaft 22, for the pivot pins 34 of the control roller mounting plates 35, and at the rear ends, the key-hole apertures providing the lead-in slots 52 downward into the circular enlargements 24, for the components hereafter described; the apertures in 37 later tapped if self-tapping screws are not used.

Details of a suitable form for the aforementioned over running clutch type roller are shown in FIGS. 2 and 3 for the control roller 18. On the tape contacting and guiding portion of the roller 18, a series of broad flat shallow circumferential grooves at spaced axial locations define therebetween flat circumferential lands 18a affording minimum contact area with the adhesive coated tape side. This sleeve 18 is coaxially disposed and rotatable about a fixed shaft 27, in which a pair opposed longitudinally extending sloped bottom grooves 28, providing sloping camming surfaces, receive respective round-sectioned elongated clutching elements 31 disposed therein to cooperate with the sleeve inner cylindrical wall as a clutched surface.

Each element 31 appears as a somewhat symmetrically bowed resilient wire or the like, extending substantially over the groove length with, convexity of the bow lying up the groove slope. The groove slope directions are such as to increase in depth in the counterclockwise direction as shown in FIG. 3, so that with the tape 16 moving forwardly to feed in the direction indicated by the arrow 32, and thus rotating the sleeve 18 forwardly, i.e. counterclockwise, as indicated by the arrow 33, the elements 31 declutch and permit free sleeve rotation; but upon incipient backward movement of the tape, thus starting a reverse or clockwise sleeve rotation, each element 31, particularly at its bowed top center, tends to wedge or clutch between the fixed groove slope and the inner cylindrical surface of the sleeve 8, locking the roller up, in the known operation of this type of device, thereby preventing backward tape movement or retraction.

When such a clutch is incorporated in the roller 17, the shaft 22 assumes the above described structure and function of the fixed shaft 27, but its groove slopes are, of course, reversed in orientation from that shown in FIG. 3, because of the clockwise rotation of 17 on forward feed. Then, especially advantageously in combination with the same clutch structure present in 18, the axial spacing between the two rollers may be substantially fixed.

As shown in FIG. 1, the shaft of the roller 18 is secured, e.g., in the shouldered riveted manner previously described for shaft 22, between the lower ends of the link or pivot plates 35 pivotally mounted on the inside faces of the respective side plates 11 by pivot pins 34; the link plates having respective cut-out slots 36 through which the shaft 22 extends, to allow swinging of the link plates and thereby of the roller 18 eccentrically relative to roller 17.

Since the common axis of pivots 34 lies forward of the plane of the axes of rollers 17 and 18, a forward swinging tendency swings roller 18 away from 17, thus releasing the pressure of roller 18 holding the tape against the surface of roller 17; so that forward feed can take place with minimum effort; and therefore also the tape initially can be easily threaded between rollers 17-18. But tape retraction or reversal, in pulling roller 18 rearwardly and causing pivoting about 34 toward 17, thereby causes the pressure of the roller 18 increasingly to engage the tape therebetween to prevent tape retraction, due to the braking clutch action communicated through adherance of the adhesive tape side on roller 18.

An assembly providing the shaft 23, (see FIG. 7) comprises two coaxial aligned like pieces 23a, 23a axially shiftable inwardly into and biased outwardly from the casing tube 49 by virtue of a spiral compression spring 50 interposed between their inner ends 23b, 23b enlarged to provide radial shoulders engaging with corresponding counterbore stop shoulders of the respective tube halves 49a and 49b. The latter having interfitting male and female tapered portions secured together by any suitable means, for example, adhesive or the like, or press fitting into hub 13. The entire shaft assembly is press fitted into the hub of the drum structure 13.

Further each shaft portion 230 (of plastic such as a polyacetal resin or polyamide resin, e.g., Nylon) has a rounded and reduced end or pilot portion 51a smaller in diameter than the main shaft end portion 53a joined thereto by a taper 53b; while the rear end of each side plate 11 has punched therethrough a keyhole shaped aperture providing a downward lead-in slot 52, in width substantially equal (with a slight sliding clearance) to the diameter of portions 51a leading into a central round aperture 24 providing the previously named shaft joumalling aperture or bearing corresponding (with slight running clearance) to the diameter of the respective main shaft end portion 53a.

This arrangement permits the shaft end portions 51a to be pressed inwardly, by the thumb and fore-finger of one hand, against bias spring 50 until they align with slots 52 and the main shaft end portions 53a also clear holes 24, whereupon the entire drum assembly may be slid upwardlyout of slots 52 for removal of the paste board spool of a used roll and replacement by a new roll. By reverse operations the reloaded drum is reinserted, and upon release of finger pressure, the outwardly biased shaft end movement is piloted to bring the full shaft end portions 530 into the apertures 24. Further with this arrangement, not only is there a quick and easy change or replacement of the supply roll, but moreover the interengaging structure of the shaft assembly with the frame prevents accidental upward displacement of the supply roll from the frame.

Since the two half shaft elements 23a are comprised of a plastic of appropriate hardness, preferably a polyacetal resin or a polyamide resin, e.g. Nylon, even with rough stamped-out keyhole openings, wall surfaces of the rough bores 24 and slots 52 are smoothed out by being coated during first use with plastic material rubbed off onto the wall surfaces thereby providing an ideal bearing running surface. Thereafter further wear or detrimental enlargement of the bearing bore 24 is no longer significantly possible during a reasonable service life of the tool.

The core or drum 13 in the form shown in FIG. 1, or in FIGS. 8-9 or, in the further modification of FIGS. 10-11, is well adapted for production as a low cost, durably functional synthetic plastic injected molded piece or the like having an elongated hub 41 in which is press fitted the assembly for shaft 23 above described.

In FIG. 1, a plurality, seven, of integral radial reinforcing gussets or ribs 25 extend from the hub 41 back to the radial rear wall 42 and partially to the approximately internal cylindrical surface of the integral roll supporting sleeve portion 26, somewhat after the fashion indicated in FIGS. 10 and 11 for a modification.

In FIGS. 8-9, the core or drum 13, is modified from HO. 1 insofar asthe back wall 42 is radially enlarged to form a flange-like, circumferentially continuous, tape spool stop rim 43 at the broader end of the slightly conical or tapered external surface of the drum wall 44, thereby to prevent the supply roll spool from being pushed axially too far upon the drum.

FIGS. 10-11 show a still further drum modification wherein the drum sleeve portion 44, contrary to FIGS. 8-9, is tapered to enlarge towards the forward or free end, and also is divided by equally spaced inward slots 46, into a plurality of seven like segments or tongue sections each provided at its free end with an outward arcuate stop flange formation 48a, so that the drum may be considered as comprised of a circumferentially outward rim-flanged, externally tapering, sleeve portion divided into the aforenamed sections by the slots 46.

Radially symmetrically and centrally disposed relative to the described sections, the seven ribs 25 integrally connect the hub tube 41, the back wall 42 and a back-wall-adjacent portion of each respective section; the remaining radial free edge of each ribe providing a stop surface 45 having a spacing from the respective section increasing towards the drum mouth. This arrangement provides not only strengthening of the core 41, stiffening of the back wall 42 or over-all strength of the structure, but also prevents excessive inward deflection of the core sleeve sections to minimize the possibility of accidental breakage; and thus minimizes the plastic section thickness and material required to be used.

On the external surface of the thus divided drum sleeve portion 44 midway between each pair of the slots 46, i.e., centrally on the sections, there is formed a respective externally projecting, integral wedgeshaped rib or ridge 47, of a triangular cross section, which proceeding in a direction away from the wall 42 toward the free edge both widens in cross section and increases in height, so that as the supply roll 14 is pushed onto the rotatable drum 13, the ridges 47 bite into the paste board spool 15 to secure the roll with a firm resilient grip. With such ridges present in appropriate form, the external taper of the drum sleeve portion 44 can be more nearly cylindrical; but especially is it to be noted that they facilitate proper reception and positioning of a tape roll with an initially out-ofround spool.

The handiness of the grip 12 is increased by a projecting curved thumb support surface 61 on its rear surface (as seen in use) which tapers off and ends before the front side of the grip; so that upon grasping of the handle, the thumb comes to lie above the surface 61 and so cannot interfere with the forefinger.

For use, apart from the loading and unloading operations previously described, with the tool grip in hand, the free end 21 of the tape is applied to, and by a light pressure brought into firm adherence on, the surface to be sealed, particularly a carton; and through the handle 12 the tool is drawn along the surface away from the place of tape initial adherence; so that the tape unwinds and, through the pressure of the directing roller 17, is pressed into adherent relation with the carton surface. For severing the applied tape length, the tool is then swung upward somewhat about the axis of shaft 22 of roller 17, bringing the cutter 19 into severing engagement with the tape,

The tape pressing finger 20 may then be used, after the application and severance of the tape, finally to press or wipe into place the terminal end of the applied tape length insofar as this is necessary We claim:
