Description
~ ~ 219QS~
This invention relates to label dispensing apparatus.
Especially the invention relates to label dispensing apparatus of the type having a reel of composite tape having self adhesive labels on a removable backing tape.
Prior art label dispensing apparatus comprise a feed roller to carry a reel of composite tape having labels affixed to a backing tape, and a take-up roller to wind up discarded backing tape after a label has been dispensed from it. The take-up roller is parallel to the reel roller and located so that the longitudinal axis of the backing tape is in the same plane on both rollers.
The path of travel of the tape from the reel to the take-up roller passes through an acute angle to bend sharply away from the labels located on it. This may be achieved by means of a peeler plate located in the path of travel of the composite strip of labels and backing tape issuing from the reel. The peeler plate is forward of both rollers so that the tape travels first forwardly from the reel and then makes a sharp turn rearward to travel rearwardly and downwardly to the take-up roller. As the composite strip turns through a sharp angle there is a tendency for the label to separate from the backing tape. The peeler plate may be provided with side flanges to guide the backing taPe so that the longitudinal axis remains in the same plane.
Rollers may be provided above the peeler plate. One of these rollers may be a rearward roller to exert some pressure on the label downwardly towards the backing tape to provide a base from which the label may spring upwardly from the backing tape as the backing tape bends rearwardly and downwardly away from it. A forward roller may limit any upward spring of the label from the backing tape as it separates from it and may guide the label forwardly in the predetermined path.
~ 2~5~
Frequently, the take-up roller is driven by an electric motor in steps limited to the length of the label, this being measured in the longitudinal direction of the backing tape.
Large label dispensing apparatus may include several transverse rows of labels on a single backing tape. Small label dispensing apparatus may be designed for use with only a narrow backing tape carrying an elongate label. The take-up roll may be operated by means of an electric motor triggered with a trigger or brake as described or, in very unsophisticated label dispensing apparatus it may be manually driven. The peeler plate may or may not be provided with rollers for manipulation of the label.
The stepping of the electric motor by switching it on or off or by the engagement and disengagement of gear means for the take-up roller may be operated by means of a light trigger forward of the peeler plate and locatable to be a distance from it corresponding to the length of a label.
Such label dispensing apparatus are well known and examples of them are described and claimed in U.S. Patents Nos.
3,941,278 issued March 2, 1976 to Oglander et al, and 4,194,646 issued March 25, 1980 also to Oglander et al.
Whatever the previously known details of label dispensing apparatus of this type, there have been limitations on their use. For the label to separate satisfactorily when the backing tape is bent sharply away from it, the label itself must have appreciable resllience.
Thus when a label is made of very thin, fine material or is very soft, it may be possible to bend it at the sharp angle with the backing tape and fail to separate from it. When a label operated trigger for stepping the electric motor is provided, the label must be of sufficient resllience and be presented properly to operate the trigger.
In order to feed wide backing tapes posslbly having several rows of labels thereon, considerable support for the peeler plate must be provided possibly by mounting each end of the peeler plate in a support member. The result has tended to be a heavy machine especially when an electric motor is included. Lightweight machines for desktop use have been provided by supporting only one end of the peeler plate on a support member and dispensing with a support member distant from the electric motor. This has resulted in a practical limitation on the length of the peeler plate and, as a result, the width of the backing tape. This limitation is greater when the support member is formed from lightweight plastics material in an attempt to reduce the overall weight of the machine.
The inventor has attempted to improve the design of known label dispensing ~h~n~5 mainly by improving the peeler plate mechanism. Firstly the inventor has attempted to provide a label dispensing machine in which tilt of the peeler plate is easily adjustable whereby a label may be dispensed at an optimum, consistent presentation, and the feed path of the composite strip comprising the backing sheet and the labels is ad~ustable for optimum peel off of the labels. The front edge of the peeler plate is bevelled to improve the sharpness of the angle for the rearward run of the backing tape from which the label has been dispensed.
When the label dispenser only has one support member and the support member is sturdily formed of lightweight metal such as anodized aluminum. A suitable thickness for a support member plate may be 1/4 inch.
' ~ 21gOS43 The invention will now be described with reference to = -the following drawings in which:
Figure 1 shows desk top label dispensing apparatus as known in the art;
Figure 2 shows desk top label dispensing apparatus according to the invention;
Figure 3 shows a detail of the peeler plate fixing means of the label dispensing apparatus of Figure 2;
Figure 4A is a sketch showing the peeler plate in one position and the reel of composite scrip being full;
Figure 4B is a sketch similar to that of Figure 4A but showing the peeler plate in a different position and the reel approaching its empty conditioni and Figure 5 is a working sketch showing another embodiment of the invention.
The drawings show label dispensing apparatus 10 having a feed roller 12 carrying a reel 14 of composite strip comprising backing tape 16 and self adhesive labels 18 temporarily adhered to the backing tape. The label dispensing apparatus 10 also has a take-up roller 20 driven through an electric motor 22. The composite strip comprising backing tape 16 and labels 18 is fed from reel 14 forwardly across peeler plate 24 and then sharply changes direction through acute angle (I to wind onto take-up roller.
It is important that the longitudinal axis of the tape remains in the same plane through out the operation. Take-up roller 20 and feed roller 12 are parallel one with the other and peeler plate 24 located forwardly of both rollers may be provided with guide flanges 26 to help keep the longitudinal axis of the tape in the same plane. A foot 25 is provided for stability ~ 21~5~3 A further guide may be provided by support wall member :~
28, to which roller 12, take-up roller 20 and peeler plate 24 are all attached. As shown, the rollers 12, 20 and peeler plate 24 are attached at one end only to one support wall member 28. For larger machines a second support member may be provided for the distal end of peeler plate 24. The support member 28 in such prior art machines may be a rigid plastics material sheet. For desk top machines a handle aperture 27 may be punched in a top part of the support.
The peeler plate 24 is provided with a rear roller 30 comprising a tube coaxially about a support rod which extends through guide flanges 26 of the peeler plate 24 at each end thereof and, at one end through support member 28.
At the end of rear roller 30 which is mounted on support member 28, the rear roller 30 is held in position by means of knurled end cap mating with a screw threaded end of the rod which projects through support member 28. At the distal end of rear roller 30 the cylinder may be secured on the rod by a knurled end cap 34.
A forward roller 36 is provided to locate labels 18 which peel off the backing tape 16. This forward roller 36 is secured by blind nuts 38 in screw threaded engagement with a rod extending through the roller 36 and guide flanges 26.
lt may be seen that the location of peeler plate 24 may be adjusted by pivoting the peeler plate 24 on the rear roller and tightening the knurled knobs to hold it firmly in place. Tt may also be seen that if the knobs are not tightened sufficiently the position of the peeler plate may slip from that at which it is initially set.

2~9~5~3 Figure 2 shows a label dispenser according to the invention and Figure 3 shows detail of the modified mounting of the peeler plate~in apparatus according to the invention.
Significant advantages may be obtained by such modified peeler plate mounting. In Figures 2 and 3 similar parts will be referred to by similar reference numerals to those of Figure 1 but reference numerals used with reference to the peeler plate 24 and its mounting are different since many of the functions are different.
Tn apparatus according to the invention a peeler plate 40 freely pivotally mounted on a support wall member 28 at the end of a front roller 42 of the peeler plate 40. The support wall member 28 may be 1/4 inch anodised aluminum plate and may, for desk top models have a handle aperture 27. The edge of the aperture 27 may be smoothed into a curve to make it more comfortable for hand carrying.
The pivotal connection of the peeler plate 40 may be by any convenient means but conveniently comprises a solid front roller 42 having a stub axle 44 which pro~ects through a bearing aperture of support 28 and through the adjacent guide flange 45. The stub axle 44 is provided with an end cap to prevent accidental withdrawal of the stub axle 44 from the aperture 42 of support 28. The end cap 46 may conveniently be in the form of a screw threaded cap. A
similar stub axle 44 and end cap 46 may be provided through the guide flange at the distal end of the roller 42 lodged in a bearing of the guide flange 45 at said distal end.
The position of the peeler plate may be set by means of lock nut 48 on bolt 50 which is located in curved slot 52.
The curved slot 52 is curved radially with respect to its centre which is the axis of stub axle 44. solt 50 may at g~43 its other end extend lnto a rear roller 51 acting downwardly on the composite tape.
Peeler plate 40 has a bevelled front edge 41, the sharp edge of the bevel being uppermost to sharpen the angle through which the tape 16 must bend in its path to take-up roller 20. Peeler plate 40 also has an appreciable distance of plate extending forwardly of forward or pivot roller 42.
Such forward distance of plate may act as guide for a label and balances pivoting of the plate about forward roller 42.
Since balanced pivoting is possible, a more sturdy peeler plate may be possible than has been the case for known prior art apparatus.
The above described arrangement of the peeler plate 40 mounting may allow for ~uick and easy ad~ustment of the peeler plate. Figures 4A and 4B show the peeler plate 40 ad~usted with its tilt at one angle in Figure 4A when take-up roller reel 14 is full or nearly full and with its tilt at a different angle in Figure 4s for use when the take-up roller is empty or nearly empty. By the use of such adjustment the angle at which the backing tape is pulled away from the label can be ad~usted towards a constant value irrespective of the amount of backing tape wound on the take-up roller, thus allowing for exact presentation of a dispensed label in the same orientation whether or not the feed reel is full or nearly empty. The presentation of the dispensed label is of importance in operating a trigger 54 for the electric motor 22 to stop feed of the tape 16 when a label 18 has been dispensed but has not been removed from the apparatus.
Moreover, since solid rollers may be used the whole apparatus may be assembled with less parts than the known ~ 219~543 prior art machines resulting ln reduction ln manufacturing costs.
In the past, operation of the electric motor 22 to stop its operation intermittently at accurate steps corresponding to the dispensing of each label has been difficult. Tt has been so difficult that U.S. Patent No. 4,194,646, referred to above, described and claimed in manually operated apparatus to overcome the problems which arose when using electric motors. Since that time, a practical system for stepping the electric motor has been devised and is described below. This system however is very dependent upon the presentation of the label as it is dispensed.
A practical embodiment of an operating system for stepping the motor 22 comprises a trigger 54 located on a pivotal arm 55 on the support 28 and locatable in the path of a label 18 which is peeling off the backing tape 16 as it is being dispensed. The trigger 54 is a hair trigger and, when the label 18 presses against it, moves to stop the motor 22 and thereby stop rotation of the take-up roller 20 and the movement of the dispensed label 18 is halted with the label 18 in a position for manual removal and use. When the label 18 is removed, pressure on the trigger 54 is also removed and it moves to allow the electric motor 22 to rotate the take-up roller 20 to dispense another label 18.
It may be seen that presentation of the dispensed label 18 is all important in operation of the trigger 54.
A further illl~lUV~ t offered by the invention is the provision of a separator strip 57 forward of the forward roller of the peeler plate. The separator strip 57 may comprise a narrow sliver of spring steel directed to lightly touch the surface of the tape 16 just downstream of the point where separation of the label 18 of the backing tape ~ 21~054~
g 16 is expected in the region of the mid part of the label but, preferably, the separator strip 57 will extend the width of the label to act over the entire length of the front edge of the label. If the label is adhered a little too firmly to the backing tape and does not start separating therefore at the point expected, the edge of the label will encounter the tip of the spring steel sliver which will act to help it lift from the backing tape.
The spring steel sliver may be an elongate sliver attached at one end to the forward roller and extending downwardly and forwardly to gently scrape tape passing beneath it and to hook or otherwise encourage lifting of the forward edge of the label 18 passing beneath it. This sliver may also add guidance to a label which has lifted off the backing tape 16 so that it is presented to the trigger 54 in a correct and accurate presentation.
Roller 12 may be located on a rearwardly and upwardly extending leg 56 of support member 28 (see Figure 5). This may be useful when a large reel is to be used which, on desktop models, might foul the operation of take-up roller 20. It is also possible to provide various mounting points 58 on the leg 56 on support 20 for feed roller 12 so that the angle of approach path of composite tape comprising backing tape 16 and labels 18 may be ad~usted to alter the value of angle a if desired.
Angle c~ is preferably as sharp as possible but conveniently may be between say 10 and 45~ up to even possibly as much as 90~.
Significant advantages may be obtained by such modified peeler plate mounting. In Figures 2 and 3 similar parts will be referred to by similar reference numerals to those of Figure 1 but reference numerals used with reference to the peeler plate 24 and its mounting are different since many of the functions are different.
Tn apparatus according to the invention a peeler plate 40 freely pivotally mounted on a support wall member 28 at the end of a front roller 42 of the peeler plate 40. The support wall member 28 may be 1/4 inch anodised aluminum plate and may, for desk top models have a handle aperture 27. The edge of the aperture 27 may be smoothed into a curve to make it more comfortable for hand carrying.
The pivotal connection of the peeler plate 40 may be by any convenient means but conveniently comprises a solid front roller 42 having a stub axle 44 which pro~ects through a bearing aperture of support 28 and through the adjacent guide flange 45. The stub axle 44 is provided with an end cap to prevent accidental withdrawal of the stub axle 44 from the aperture 42 of support 28. The end cap 46 may conveniently be in the form of a screw threaded cap. A
similar stub axle 44 and end cap 46 may be provided through the guide flange at the distal end of the roller 42 lodged in a bearing of the guide flange 45 at said distal end.
The position of the peeler plate may be set by means of lock nut 48 on bolt 50 which is located in curved slot 52.
The curved slot 52 is curved radially with respect to its centre which is the axis of stub axle 44. solt 50 may at g~43 its other end extend lnto a rear roller 51 acting downwardly on the composite tape.
Peeler plate 40 has a bevelled front edge 41, the sharp edge of the bevel being uppermost to sharpen the angle through which the tape 16 must bend in its path to take-up roller 20. Peeler plate 40 also has an appreciable distance of plate extending forwardly of forward or pivot roller 42.
Such forward distance of plate may act as guide for a label and balances pivoting of the plate about forward roller 42.
Since balanced pivoting is possible, a more sturdy peeler plate may be possible than has been the case for known prior art apparatus.
The above described arrangement of the peeler plate 40 mounting may allow for ~uick and easy ad~ustment of the peeler plate. Figures 4A and 4B show the peeler plate 40 ad~usted with its tilt at one angle in Figure 4A when take-up roller reel 14 is full or nearly full and with its tilt at a different angle in Figure 4s for use when the take-up roller is empty or nearly empty. By the use of such adjustment the angle at which the backing tape is pulled away from the label can be ad~usted towards a constant value irrespective of the amount of backing tape wound on the take-up roller, thus allowing for exact presentation of a dispensed label in the same orientation whether or not the feed reel is full or nearly empty. The presentation of the dispensed label is of importance in operating a trigger 54 for the electric motor 22 to stop feed of the tape 16 when a label 18 has been dispensed but has not been removed from the apparatus.
Moreover, since solid rollers may be used the whole apparatus may be assembled with less parts than the known ~ 219~543 prior art machines resulting ln reduction ln manufacturing costs.
In the past, operation of the electric motor 22 to stop its operation intermittently at accurate steps corresponding to the dispensing of each label has been difficult. Tt has been so difficult that U.S. Patent No. 4,194,646, referred to above, described and claimed in manually operated apparatus to overcome the problems which arose when using electric motors. Since that time, a practical system for stepping the electric motor has been devised and is described below. This system however is very dependent upon the presentation of the label as it is dispensed.
A practical embodiment of an operating system for stepping the motor 22 comprises a trigger 54 located on a pivotal arm 55 on the support 28 and locatable in the path of a label 18 which is peeling off the backing tape 16 as it is being dispensed. The trigger 54 is a hair trigger and, when the label 18 presses against it, moves to stop the motor 22 and thereby stop rotation of the take-up roller 20 and the movement of the dispensed label 18 is halted with the label 18 in a position for manual removal and use. When the label 18 is removed, pressure on the trigger 54 is also removed and it moves to allow the electric motor 22 to rotate the take-up roller 20 to dispense another label 18.
It may be seen that presentation of the dispensed label 18 is all important in operation of the trigger 54.
A further illl~lUV~ t offered by the invention is the provision of a separator strip 57 forward of the forward roller of the peeler plate. The separator strip 57 may comprise a narrow sliver of spring steel directed to lightly touch the surface of the tape 16 just downstream of the point where separation of the label 18 of the backing tape ~ 21~054~
g 16 is expected in the region of the mid part of the label but, preferably, the separator strip 57 will extend the width of the label to act over the entire length of the front edge of the label. If the label is adhered a little too firmly to the backing tape and does not start separating therefore at the point expected, the edge of the label will encounter the tip of the spring steel sliver which will act to help it lift from the backing tape.
The spring steel sliver may be an elongate sliver attached at one end to the forward roller and extending downwardly and forwardly to gently scrape tape passing beneath it and to hook or otherwise encourage lifting of the forward edge of the label 18 passing beneath it. This sliver may also add guidance to a label which has lifted off the backing tape 16 so that it is presented to the trigger 54 in a correct and accurate presentation.
Roller 12 may be located on a rearwardly and upwardly extending leg 56 of support member 28 (see Figure 5).
