T DISPENSING DEVICE I Filed 0on5, 1962 s Sheets-Sheet a INVENTOR. EDWARD WALTZ ATTORNEYS United States Patent 3,186,613 SHEET DESPENSEJG DEVICE Edward Waltz, Grand Rapids, Mich, assignor to E. 0. Euiman Manufacturing Company, Inc, Grand Rapids, Mich, a corporation of Michigan Filed Oct. 5, 1962, Ser. No. 228,651 4 Claims. (Cl. 225-80) This invention relates in general to a device for dispensing sheet material from a supply thereof and, more particularly, to a dispensing device of this character which is especially designed for guiding the movement of a strip of material, such as film or foil, from a roll thereof and for severing a portion of the strip from the roll.

Various types of devices have been widely and successfully used for many years to dispense sheet materials, such as paper, from a roll thereof. One such device is disclosed in US. Patent No. 2,234,818, issued to Elvah O. Bulman. However, it has been found that many moistureproof sheets, such as plastic films and metallic foils,

which can be advantageously used in wrapping operations, are not properly handled by existing dispensing devices. More specifically, most of the cutting and guiding mechanisms on present dispensing devices were originally designed for handling paper. Accordingly, the use of films and foils has often been made inconvenient and has sometimes been curtailed for the lack of a dispenser having a satisfactory cutting and guiding mechanism. Where the sheet materials have been laminated and/or reinforced with threads, such as glass fibers, of high tensile strength, the existing dispensers have been virtually useless.

In the course of considering this problem, it developed that a completely new approach would be required for producing a satisfactory cutting and guiding mechanism and that little improvement could be expected from merely reworking the existing mechanisms presently used to handle the weaker materials. That is, whereas existing devices for supporting a roll of paper, incident to dispensing thereof, can be satisfactorily used to support rolls of film or foil, or various combinations thereof with other materials, the existing guiding and severing mechanisms associated with such devices have not as yet been satisfactorily modified for cutting films and foils.

It was also found that the various types of film, foil and reinforced sheets often require different types of cutting edges to produce a satisfactory severance of the material from a roll thereof. For best results, a cutting mechanism having the proper cutting edge should be available for quick attachment to the dispensing device and should be easy to use with its corresponding material. However, it has been found that existing dispensing devices are infrequently adapted for such versatility and, therefore, even if their cutting mechanisms are capable of satisfactory performance with one type of film or foil, they are often unsatisfactory for other types.

Stripping of the cut edge of the sheet material away from the cutting mechanism for easy and safe, manual engagement has also become a serious problem, particularly where films are involved, because there is an inherent tendency for films to cling to the frame and/ or cutting mechanism on the existing dispensers of films. Some attempts, one of which is disclosed in my copending application Serial No. 208,328, filed July 9, 1962, have been made in the past to overcome this problem. The present invention was conceived in a continuing effort to provide a further solution of this problem.

Under some circumstances, it is at least desirable, if not necessary, to wrap certain types of articles with materials through which air can pass rather freely. This requirement has created a serious problem where moistureproof lCe films are being used, particularly if the film has been intentionally selected so that other articles can be wrapped in an air-tight package. To meet this problem, it has been necessary to perforate the film for certain uses. Existing devices for eifecting such perforation have not been especially convenient. v

In addition to solving the above problems, the dispensing device of the invention has been designed so that it can be easily adapted to a variety of different uses. That is, the invention may be applied to dispensing devices used in a package wrapping department, or'along a production line, or at a check-out station in a retail store.

Accordingly, a primary object of this invent-ion has been the provision of a device for receiving a strip of sheet material, such as film or foil, from a roll thereof supported adjacent to or upon the device, and for severing a portion of such material from the strip thereof neatly, easily, accurately and Without damaging in any way the severed portion or the remainder of the material from which said portion was severed.

A further object of this invention has been the provision of a dispensing device, as aforesaid, which has a sheet guiding mechanism adapted to handle a variety of sheet materials with equal efficiency, and which has a severing mechanism capable of handling different sheet materials without substantial modification, if any, in such dispensing device.

A further object of this invention has been the provision of a dispensing device, as aforesaid, which is capable of supporting the roll of sheet material, and which can be adapted to support an article to be wrapped in the sheet material dispensed by the device.

A further object of this invention has been the provision of a dispensing device, as aforesaid, which is inexpensive to produce, which is easy to install, which is simple and safe to operate, which requires little or no maintenance, and which has a pleasing appearance.

Other objects and purposes of this invention will become apparent to persons familiar with this type of equipment upon reading the following descriptive material and examining the accompanying drawings in which:

The terms inner, outer and derivatives thereof will have reference to the geometric center of said dispensing apparatus and parts thereof.

General description The objects and purposes of the invention, including those set forth above, have been met by providing a device for receiving a strip of sheet material from a supply, such as a roll, thereof and for guiding and/ or controlling the movement of the strip from the roll to a mechanism for severing a piece of the 'strip from the roll. The guiding mechanism includes a flat, flexible member over which the strip. of. material passes and which moves the cut edge of the strip away from the severing mechanism, after a severing operation is performed.

In a modified embodiment, the frame of the dispensing device is enlarged to provide support for a roll of the sheet'material and to provide a platform upon which articles can be wrapped in the sheet material severed from the roll thereof. The roll-supporting structure includes a pair of spaced and parallel rollers at one end of the frame. In a further modification of the invention, the dispensing device includes roll-supporting structure and means which is movable int o andout of position for perforating the sheet material.

Detailed construction The dispensing device (FIGURES l and 2), which has been selected to illustrate one embodiment of the invention, is comprised of a frame structure 11, a guide mechanism 12 and a cutting member or mechanism 13. In one particular embodiment of the invention, as shown in FIGURE 1, the frame structure 11 is substantially rectangular in shape and includes a base plate 14 and a pair of parallel end plates 16 and 17, which are rigidly secured to and extend perpendicularly away from the opposite ends ofthe base plate 14.

The cutting member 13 (FIGURES '1 and 2) includes an elongated substantially rigid angle member 18 having a pair of angularly disposed lengthwise flanges 19 and 20. The opposite ends of the side flange 20 (FIGURE 3) are bent over to form a pair of end flanges .23 and 24 (FIGURE 1),.which are secured to the end plates 16 and 17, respectively, by means such as the screw 26. Accordingly, by loosening the screws 26, the angle member 18 can be adjusted around its lengthwise axis.

An elongated, flat and substantially rigid blade 27 is secured to and upon the outer surface of the side flange 20 so that the cutting edge 28' of said blade, which is serrated in this. particular embodiment, extends slightly above or beyond the adjacent surface of the top flange 19..

The cutting member 13 extends between the corners of the end plates 16 and 17 defined by their upper and rearward edges 31, 32 and 33, 34, respectively.

The guide mechanism 12 includes upper and'lower guide rollers 37 and 38 (FIGURES 1 and 3) which are rotatably, supported inspaced parallel relationship upon and between the end plates 16 and 17. More specifically, the upper guide roller 37 has end portions 39 and 40 (FIGURES 1 and ,5) which are of reduced diameter and are rotatably disposed within the openings 42 and 43 in the end plates 17 and 16, respectively. The lower roller 38 has similar end portions of reduced diameter which extend through corresponding openings. in said end plates 16 and 17. The guide rollers 37' and 38 are located near the'corners of, the end plates 16 and 17 defined by the upper edges 31 and 32 thereof and the front edges. 44 and. 45 thereof.. The upper guide roller 37 is substantially closer to the upper edges of the side plates than to. the frontedges of the side plates and the lower roller 38 is substantially closer to the front edges of the side plates than to the upper edges thereof.

The guide mechanism 12 also includes -an adjustable sheet guide 47 which extends perpendicularly between and is. supported upon the end plates 16 and 17, and it is" located between the cutting member 13 and the guide rollers 37 and 38. That is, said sheet guide 47 extends upwardly .and rearwardly from a line below the upper guide roller 37. The sheet guide 47 (FIGURES 1 and 3) includes an elongated and substantially rigid support element 48 which may be similar in construction and shape which are adjustably secured to the opposing surfaces of the end plates 16 and 17 by the screws 56. Accordingly, the position of the element 48ar0und its lengthwise axis can be adjusted by loosening the screws 56, rotating said element 48 and thereafter tightening the screws.

A thin, elongated and substantially flat guide member 57, which is fabricated from resiliently flexible material, such as plastic, fiberglass or metal, is secured along one edge thereof upon the flange 51, which is near to but spaced from the lower guide roller 38. The guide member 57- is here shown as being transparent, which is desirable, but it can betranslucent or opaque if desired. In this particular embodiment, the guide member 57 is secured upon said flange 51 by an elongated metal strip 58, which is preferably about as long as the side flange 51, and by the rivets or screws- 59. 'The guide member 57 is preferably of such width that its free edge extends almost to, but does not touch, the adjacent edge of the top flange 19 on the angle member 18, when the guide member 57 is bent toward said angle member 18 (FIG- URE 3). Under normal circumstances, the support element 48 is positioned, as appearing in FIGURE 4, so that the guide member 57 bears snugly against the upper guide roller'37, which is almost directly above they support element 48. The amount of pressure between the guide member 57 andthe upper roller 37 can be adjusted by rotating the support element 48 in one rotational direction or the other around its lengthwise axis.

As shown in FIGUREZ, the dispensing device 10 can be employed in conjunction with a substantially conventional rack 62 having a shaft 63 for rotatably supporting a roll .64 of sheet material 66, suchras moistureproof film, foil, paper :or the like. Moreover, the dispensing device 10 and the rack 62 can be used'in conjunction with a conveyor 67 upon which thepieces68 of sheet material 66 are placed after theyare severed from the roll thereof.

Operation In using the dispensing device 10,. a companion unit, such as the .rack' 62(FIGURE 2 is normally required to support the roll 64 of sheet material, which is fed through the dispensing device. As shown in FIGURE 4, the sheet material 66 maybe fed over the lower guide roller 38 andthen under the upper guide roller 37 so that it is resiliently pressed against the upper guide roller by the resiliently flexible guide member 57. Normally, the guide member 57 will'be in its FIGURE 4 position, thereby holding the edge 69. of the sheet material 66 upwardly away from the cutting edge 28 on the blade 27.. This serves, to. minimize injury to "the hand of the operator, who must grasp the free edge 69 of the sheet material 66 to initiate a dispensing operation.

When it becomes desirable to remove a piece 68 of sheet material from therroll 64 thereof, the free edge 69 of the sheet material ismanually engaged and pulled rearwardly away from the guide mechanism 12 beyond, and rearwardly of, the cutting edge 28. When the proper amount of'sheet material extends beyond thelcutting edge 28, the'sheet material is moved downwardly-so that it engages the cutting edge 28, whereby the piece is severed from the remainder of the roll. The guide member 57 is bent downwardly (FIGURE 3) during the downward movement'of the sheet materialtoward the cutting edge 28. The resistance of the guidemember '57 to such downward movement is'relatively small. However, when the severing operation is completed, the guide member 57 promptly moves upwardly from its FIGURE 3 position into its FIGURE 4 position, thereby moving the edge 69 of the sheet material66 away from said blade 27. The engagement of the sheet material 66 between the guide member 57 and upper guide roller 37 prevents the sheet Alternate structure The modified'dispensing device 71 (FIGURES 6 and 7 includes a frame structure 72 which supports near one end thereof a severing member '73 and a guide mechanism 74. The frame structure 72 includes an elongated base plate 75 and a pair of upstanding, parallel and integral side plates 76 and 77, which extend upwardly from the lengthwise edges of the base plate. The guide mechanism '74 includes an upper guide roller 80, a lower guide roller 81 and a sheet guide 82 which are preferably similar in construction and relative locations to the guide rollers 37 and 38 and the sheet guide 47 of the dispensing device it).

A partition 83 (FIGURES 7 and 8), which is mounted within the frame structure 72, extends between the side plates 76 and 77 and upwardly from the base plate 75, so that the upper edge of said partition is horizontally aligned with and near to the support element 84 of the sheet guide 82. The partition 83 serves not only to strengthen the frame structure 72, but also to block access to the space within the frame structure 72 frontwardly of the guide mechanism 74.

he severing member 73 is, in this particular embodiment, a wire element which is heated in a conventional manner for the purpose of severing film. However, a

cutting member, such as that indicated at 13 in the dispensing device 1%), can be used in place of the heated wire 'member 73. The severing member 73 may be electrically connected by the conductors 85 and 86 to'a transformer 91 which is connected to a standard source of 110 volt electrical potential.

A pair of spaced and parallel rollers 87 and $8 are supported upon and extend between the side plates 76 and 77 near the front ends thereof. The rollers $7 and 88 have reduced end portions, two of which are indicated at 39 and 90 (FIGURE 6), which are slidably and rotatably received through appropriate openings, such as the openings 3 and 94 in the side plates 76 and 77. As shown in FKGURE 7, the rollers 87 and 88 are arranged to support a roll 96 of sheet material 97, such as film, foil or a er.

p g fiat shelf member 98, which is preferably rectangular in shape, is supported upon the upper edges of the side plates 75 and 77 and extends therebetween substantially parallel with the base plate 75. The shelf member 98 has a downwardly extending flange 99 extending along its edge for strength purposes and for positioning said shelf member upon the side plates. A brace bar 192 is secured to and extends between the side plates 76 and 77 directly beneath and spaced from the front roller 87. A thumb screw 163 is threadedly received upwardly through the brace bar 1%2 for engagement with the front roller 87 to control or brake its rotational movement, and thereby prevent overrunning of the roll 96 of sheet material during an unwinding operation.

The operationof the dispensing device 71, insofar as the guiding of the sheet material by the guide mechanism 74 and the severing of the sheet material by the severing member 7 3 are concerned, may be substantially the same as discussed above with respect to the dispensing device 1ft. That is, with the roll 96 supported upon the rollers 87 and 33, the sheet material 97 is threaded from the roll beneath the shelf member 98, over the lower guide roller 81 and beneath the upper guide roller 39 so that the sheet material is pressed'by the sheet guide 82 against the upper guide roller 3%. When a piece of the sheet material s7 is required, the free end of the sheet material adjacent the sheet guide 82 is manually engaged and pulled away from the sheet guide 82 over the severing member 73 until the right amount of such material is withdrawn. Then the material is moved downwardly so that it engages the severing member 73 and is thereby separated from the remainder of the roll. The resiliently flexible sheet guide 82 moves the severed edge of the sheet material on the roll away from the severing member so that the operation can be immediately and safely repeated.

The sheet material 97 can be moved away from the guide, mechanism 74 beneath the severing member 73 so that the severing operation. is performed by moving the sheet material upwardly. This arrangement may be particularly convenient where the severed piece of material is placed upon the shelf member 9?) for the purpose of wrapping a package indicated in broken lines at 1% in FIGURE 7.

In an alternate operation of the dispensing device 71, the sheet material may be threaded, as indicated in FIG- URE 7, by the broken line 97a, over the shelf member 98, under the upper guide roller 89 and thence over the sheet guide 82.

FIGURES 9 and 10 illustrate a modified dispensing device 119 having a frame structure 111 which is similar to, but somewhat shorter than, the frame structure 72. The guide mechanism 112 and severing member 113 may be identical with the corresponding parts 74 and 73, respectively, in the dispensing device 71. Likewise, a roll 114 of film 115, for example, is supported upon the frame structure 111 by a pair of spaced and parallel rollers 116 and 117.

A perforating roller 118 is adjustably and rotatably supported upon and between the'side plates 121 and 122 of the frame structure 111, so that said roller 113 is movable into and out of a position parallel with and near to the roller 117. That is, the side plates 121 and 122 have similar, opposing slots 123 and 124 which are substantially L-shaped. Said slots 123 and 124- have vertical legs 126 and 127, respectively, and sloping legs 128 and 129 which decline rearwardly from the upper ends of the vertical legs 1% and 127, respectively. The opposite ends of the roller 118 extend through and are movable along the slots 123 and 12 t. The roller 11% has integral barbs or pins which are capable of perforating a film which is passed over the barbs. The roller is inoperative when it is at the lower ends of the vertical legs 126 and 127. The roller is moved upwardly and then rearwardly into the sloping legs 128 and 129 where it can produce said perforations in the film 115. The rings 131 on the roller 117 prevent excessive axial movement of the roll 114.

Although particular preferred embodiments of the invention have been disclosed above in detail for illustrative purposes, it will be understood that variations or modifications of such structure, which come within the scope of the appended claims, are fully contemplated.
