TECHNICAL FIELD




The present invention generally relates to a tape applicator. The present invention relates more particularly to a tape applicator that includes a tape head having a base, a tape roll holder attached to the base and a tape application roller attached to the base for applying a tape to a surface the, where the tape applicator includes a tape path from the tape roll holder to the tape application roller, and includes a x-axis actuator operatively connected to the tape head for moving the tape applicator in the x-axis direction and a y-axis actuator operatively connected to the tape head for moving the tape applicator in the y-axis direction. The present invention also relates to a method of applying tape to surface, which includes applying a first length of tape on a surface, thereafter cutting the first length of tape at an angle oblique to the length of the tape to form a first removable portion of the first length of tape, and then removing the first removable portion of the tape from the surface.




BACKGROUND OF THE INVENTION




Various apparatuses and methods for attaching tape or labels to articles are known in the art. For example, U.S. Pat. No. 5,356,505 to Salvator discloses an applicator for evenly applying an adhesive backed foil to edges of pieces of stained glass. The applicator includes guide members, which direct a foil strip from a foil spool past an application point to a take-up reel. The take-up reel is motor driven to pull the foil from the foil spool at a constant speed and to wind up a protective backing after the backing has been removed from the foil and the foil applied to the edge of a piece of stained glass.




U.S. Pat. No. 6,030,475 to Spotts, Jr. discloses a sealant strip applying system for applying a sealant strip to a top surface of a sheet material adjacent to a plurality of straight edges. The system is configured to support the sheet material and to produce the controlled repositioning thereof on an air flotation table with each edge being selectively aligned with a front edge of the table. The sealant strip is successively applied to each edge by a sealant strip applicator that is supported by the air flotation table and mounted for selective movement along the front edge thereof.




U.S. Pat. No. 5,441,846 to Negate et al. discloses a system for the preparation of a light-sensitive material comprising a substrate, a light-sensitive layer and a base film which comprises a roller for providing a continuous light-sensitive sheet comprising the base film, the light-sensitive layer and a protective film; means for cutting the light-sensitive layer and a protective layer in the traverse direction; fixing means for temporarily fixing the sheet; a roller for providing an adhesive tape for removing the protective film; the adhesive tape-collecting roller; a bar for pressing the adhesive tape by its tip to the front end of the light-sensitive sheet and to press the front end against the bottom of the fixing means and peeling the protective film from the sheet; a dancer roll; light-sensitive sheet cutting means; substrate supplying means; and heat rollers for laminating the base film and light-sensitive layer on the substrate.




U.S. Pat. No. 4,294,644 to Anderson discloses a servomotor control labeler. The servo motor drives the label feed and employs a control system for the servomotor, which is responsive to the rate of feed or speed of the surface to be labeled as it is advanced to the labeler. The control system on receiving an instruct-to-label signal accelerates the servo motor smoothly from zero to the desired labeling speed while the surface to be labeled is advanced toward the labeler a predetermined distance and on receiving an end to labeling signal decelerates the servo motor smoothly from labeling speed to zero while the label feed is advanced a predetermined distance. The arrangement is such that upon an instruct to label signal being fed to the control system at a predetermined position of advance of the surface relative to the labeler the labeler will accelerate a label from a predetermined start position and deliver same to touch down on the surface to be labeled at the precise desired point with the label moving at the same speed as the surface and upon an end to labeling signal generated by a label feed sensor being fed to the control system the labeler will decelerate to bring the next label to be delivered to the predetermined start position in preparation for the next instructing-to-label signal.




Various types of tape are known. For example, U.S. Pat. No. 5,840,407 to Futhey et al. discloses at tape having transparent optical film made of a polymeric material that has a first smooth surface and a second structured surface for providing a simulated beveled appearance. The structured surface of the film is formed of a plurality of spaced parallel grooves, each groove being formed by a first facet which is substantially perpendicular to the first smooth surface and a second facet which makes an angle between 1 to 60 degrees with the first smooth surface. The film may be affixed to glass, the adhesive applied to the first smooth surface or the second structured surface, to simulate beveled glass. An example of tape incorporating the optical film disclosed in U.S. Pat. No. 5,840,407 is commercially available as 3M™ Accentrim™ Tape, series B200 and series B100, from 3M Company, located in St. Paul, Minn.

, so the tape does not continue to unwind from the roll


90


when the tape head


100


stops applying tape to the surface. The tape head


100


also includes a first tape guide roller


110


, a pinch roller


118


, a pivotal tape guide


122


, a first cutter


116


, an application roller


120


, and a liner take-up roller


136


, all attached to the lower base portion


106




b


. The first cutter


116


includes a fixed blade


112


and a moveable blade


114


that may be pivoted. The application roller


120


is mounted to the lower base portion


106




b


by a bracket


130


. The tape head


100


also includes an application roller air cylinder


131


for actuating the bracket


130


about pivot


133


to place the application roller


120


in contact with the tape


92


and surface


5


. The liner take-up roller


136


preferably includes a friction clutch


138


to provide tension on the liner


94


as it winds from onto the liner take-up roller


136


, to keep the liner


94


taunt.




The tape


92


preferably moves along the following path within the tape head


100


: a) from the tape roll holder


102


to the second tape guide roller


108


; b) then to the nip formed between the first tape guide roller


110


and the pinch roller


118


; c) then to the pivotal tape guide


122


; d) then between the blades


112


,


114


of the first cutter


116


, which are spread apart; e) then under the application roller


120


, which applies the tape


92


to the surface


5


. The pivotal tape guide


122


separates the liner


94


from the tape


92


, as the tape


92


passes over the tape guide


122


. After the liner


94


is separated from the rest of the tape


92


, the liner winds around the pinch roller


118


and is taken up by the liner roller


136


, as seen in more detail in FIG.


8


.




When loading a new roll of tape


90


into the tape head


100


, the tape is initially threaded through the tape head


100


according to the tape path outlined above. The pinch roller


118


is mounted on the end of a mounting slide


132


. The mounting slide may be slid away from the first guide roller


110


to allow the tape


92


in the nip between the pinch roller


118


and the first guide roller


110


. The liner


94


is separated from the rest of the tape


92


near the pivotal tape guide


122


. The liner is then wound around the pinch roller


118


and wound around the liner roller


136


.





FIG. 6

illustrates a partial isometric view of the lower portion of the base


106




b


. The tape


92


winds around the first tape guide roller


110


between two opposite tape guides


109


. The tape guides


109


assist in keeping the tape


92


straight just prior to its application to the surface


5


by the application roller


120


. The tape


92


then passes over the pivotal tape guide


122


along the guide surface


124


. The guide surface


124


includes two opposite tape guides


128


. The tape guides


128


also assist in keeping the tape


92


straight just prior to its application to the surface


5


by the application roller


120


. The tape guides


128


of the guide surface


124


are preferably aligned with the tape guides


109


in the first tape guide roller


110


. The liner


94


is separated from the rest of the tape


92


at the edge


126


of the guide surface


124


. The edge


126


of the guide surface


124


is preferably sharp to assist in separating the liner


94


from the rest of the tape


92


. Alternatively, the portion of the edge


126


located between the two tape guides


128


may be sharp, while the remaining portion of the edge


126


located outside the two tape guides


128


may not be sharp because the liner


94


does not contact the portions of the edge


126


located outside the tape guides


128


. The guide surface


124


of the pivotal tape guide


122


is pivoted clockwise so that the guide surface


124


directs the tape


92


over the fixed blade


112


of the first cutter


116


. The moveable blade


114


is pivoted away from the fixed blade


112


to allow the tape to pass between the blades


112


,


114


of the first cutter


116


. The tape is then applied to the surface


5


by the application roller


120


.





FIG. 7

illustrates the second side of the tape head


100


, which is opposite the first side of the tape head


100


illustrated in FIG.


5


. The rotary actuator


34


for rotating the tape head around the z-axis has been removed for clarity. The rotary actuator


34


is attached to the tape head


100


at bracket


107


by a shaft (not shown). The tape head


100


includes a rotary motor


164


mounted to the lower base portion


106




b


for driving the first guide roller


110


by shaft


111


through a one-way clutch bearing (not shown). The one-way clutch bearing will allow the first tape guide roller


110


to rotate freely during the tape application, but will also allow the first tape guide


110


to be driven by the rotary motor


164


when advancing the tape to the application roller


120


, after the tape is cut by the first tape cutter


116


. The tape head also includes a first air cylinder


150


attached to the lower base portion


106




b


for actuating the moveable blade


114


in the first cutter


116


. The tape head includes a second cutter


154


mounted to the lower base portion


106




b


. The second cutter


154


includes a blade


156


and a bracket


158


for holding the blade


156


. The second cutter


154


is actuated by the second air cylinder


160


about pivot


159


. The second cutter


154


cuts the tape


92


after it has been applied to the surface


5


. The rotary actuator


34


(not shown) rotates the tape head


100


about the z-axis to correctly position the blade


156


at a desired angle relative to the applied tape


92


on the sheet of glass surface


5


to allow the blade


156


to cut the applied tape


92


. Alternatively, the second cutter


154


could rotate independently of the tape head


100


and thus, not require the entire tape head


100


to rotate.





FIGS. 8-13

are useful for describing the method of applying tape to the surface


5


of the sheet of glass


2


and for cutting the tape after it has been applied to the surface


5


to form an angled end in the applied tape.





FIG. 8

illustrates the tape head


100


initially applying the tape


92


to the sheet of glass surface


5


. The tape


92


includes an adhesive layer


93


and a liner


94


covering the adhesive layer


93


. To start applying the tape to the surface, the tape end


95


is located under the application roller


120


. The application roller air cylinder


131


actuates the application roller


120


into contact with the tape


92


and the surface


5


. Once the tape


92


is between the application roller


120


and the surface


5


, the adhesive layer


93


bonds the tape


92


to the surface


5


by pressure. These steps are used to initially start applying the first end


95


of the tape


92


to the sheet of glass


2


. To continue applying tape


92


to the surface


5


, the tape head


100


moves relative to the stationary sheet of glass


2


, while the application roller


120


applies the tape


92


. The tape


92


preferably travels freely along the tape path through the tape head


100


, as the tape is being applied to the surface. To allow the tape to travel freely, the tape roll holder


102


and the first and second tape guide rollers


108


,


110


freely rotate. The second tape guide roller


110


may freely rotate independent of its motor


164


.





FIG. 9

illustrates the first cutter


116


cutting the tape


92


just prior to where the tape is applied to the sheet of glass


2


. The first cutter


116


cuts the tape


92


transversely by the first air cylinder


150


actuating the moveable blade


114


to contact the fixed blade


112


. At the same time as the moveable blade


114


moves to contact the fixed blade


112


, the guide surface


124


in pivotal tape guide


122


rotates counter clockwise to move the guide surface


124


away from the blades


114


,


116


of the first cutter


116


. The moveable blade


114


is attached to the pivotal tape guide


122


by a ball joint to allow them to move together. By cutting the tape


92


, the length of tape now has a second end


96


with a portion D yet to be applied.





FIG. 10

illustrates the second end


96


of the tape being applied by the tape head


100


. To apply the second end


96


of the tape


92


, the tape head


100


continues moving relative to the sheet of glass to allow the application roller


120


to press the remaining tape


92


against the surface


5


to bond the tape


92


to the surface


5


. The first air cylinder


150


has actuated the moveable blade


114


again to move the moveable blade


114


out of contact with the fixed blade


112


. At the same time the moveable blade


114


moves out of contact with the fixed blade


112


, the guide surface


124


in pivotal tape guide


122


rotates clockwise to move the guide surface


124


towards the blades


114


,


116


of the first cutter


116


, between the blades


114


,


116


to allow the tape


92


to pass through the first cutter


120


when the tape advances.





FIG. 11

illustrates the second cutter


154


cutting the tape after it has been applied to the glass surface


5


. The rotary actuator


134


(not shown) rotates the tape head


100


about the z-axis to a desired angle α relative to the length of the tape to accurately position the blade


156


of the second cutter


154


at a desired angle relative the applied tape on the sheet of glass


2


. Preferably, prior to the tape head rotating, the application roller air cylinder


131


actuates the application roller


120


to remove it from contacting the surface


5


. The tape head


100


then moves back and forth in the direction of the orientation of the blade


156


by the x-axis and y-axis actuator


30


,


32


to allow the blade


156


to cut through the applied tape


92


at angle α, which is oblique to the length of the tape.





FIGS. 12



a


and


12




b


illustrate the steps in cutting a first length of applied tape


200


to form a first removable portion of tape


98


and then removing the first removable portion of tape


98


from the glass surface


5


.





FIG. 12



a


illustrates one preferred sequence of cuts in the tape


92


after it has been applied to the sheet of glass


2


. The blade


156


cuts the applied tape to form a first removable portion


98


of the tape. The sequence of cuts, as shown by reference numerals


1


-


6


on

FIG. 12



a


, are all in the same direction to form two aligned cuts in the tape, but the individual cuts have been spread apart to illustrate the preferred sequence of cuts. Preferably, the blade


156


first contacts the middle of the tape


92


to start cut


1


to help cushion the blade when it first contacts the hard glass surface


5


. If the blade initially contacted the glass directly, it may damage either the glass or the blade.




The tape head


100


performs the following steps to make the cuts


1


-


6


in the first length of tape


200


illustrated in

FIG. 12



a


. First, the tape head


100


moves the blade


156


to position it in the middle of where the first oblique side


208


of the first angled end


204


will be. Second, the second air cylinder


160


actuates to place the blade


156


of the second cutter


154


ton contact the applied tape


92


. Third, the tape head


100


then moves to make cut


1


at angle α by allowing the blade


156


to freely rotate, partially cutting through the tape


92


as the tape head


100


moves. Fourth, the tape head


100


then moves in the opposite direction to allow the blade


156


to make cut


2


at angle α. Fifth, the tape head


100


moves in the opposite direction to allow the blade


156


to make cut


3


at angle α. The cuts


1


-


3


preferably cut through the tape


92


, but not through the glass surface


5


. Sixth, the second cutter


154


is actuated by second air cylinder


160


to move the blade


156


out of contact with the applied tape. Seventh, the tape head


100


then moves to position the blade


156


in the middle of where the first oblique side


214


of the second angled end


205


will be. The first oblique side


214


of the second angled end


205


is preferably parallel with the first oblique side


208


of the first angled end


204


, but off set by a distance “b,” as explained below. Eighth, the tape head


100


then moves to make cut


4


at angle α by allowing the blade


156


to freely rotate, partially cutting through the tape


92


as the tape head


100


moves. Ninth, the tape head


100


then moves in the opposite direction to allow the blade


156


to make cut


5


at angle α. Tenth, the tape head


100


moves in the opposite direction to allow the blade


156


to make cut


6


at angle α. The cuts


4


-


6


preferably cut through the tape


92


, but not through the glass surface


5


. Eleventh, the second cutter


154


is actuated by second air cylinder


160


to move the blade


156


out of contact with the applied tape. Twelfth, the tape head


100


rotates angle δ, which in one embodiment is preferably 90°, to start cutting the second oblique side


212


of the second angled end


205


and the second oblique side


210


of the first angled end


204


. The tape head


100


and blade


156


of second cutter


154


perform the second sequence of cuts


1


-


6


in a similar matter to the first sequence of cuts


1


-


6


described above.




Alternatively, a single blade could make a single cut instead of three individual cuts


1


-


3


or instead of six individual cuts


1


-


6


.





FIG. 12



b


illustrates how the first removable portion


98


is then removed from the sheet of glass


2


to form two individual pieces of applied tape out of the first length of applied tape


200


. In this case, the first removable portion


98


is in a shape similar to a butterfly. Each end of the two pieces of applied tape is angled to form angled ends


204


,


205


. The first angled end


204


has a first oblique side


208


and a second oblique side


210


. The second angled end


205


has a first oblique side


214


and a second oblique side


212


. The first angled end


204


and second angled end


205


are cut at an angle α relative to the length of the tape. Preferably, the angled ends


204


,


205


are cut to fit together to give the desired intersection


220


. Angle α may be selected for a desired appearance. For example, angle α may be


300


,


450


, or


600


or any other angle. Alternatively, each angled end


204


,


205


may include different angles α. There is a distance “a” between the two angled ends


204


,


205


of the first length of tape. Preferably, the distance “a” is between 0.3 mm and 3 mm. More preferably, the distance “a” is between 0.3 mm and 0.5 mm.

, are all in the same direction to form two aligned cuts in the tape, but the cuts have been spread apart to illustrate the preferred sequence of cuts.





FIG. 13



b


illustrates how the second removable portion


99


is then removed from the top of the first length of tape and from the sheet of glass


2


by a user to form two individual pieces of applied tape out of the second length of applied tape


202


. Also in this case, the second removable portion


99


is in a shape similar to a butterfly. Each end of the two pieces of applied tape


202


is angled to form angled ends


204


,


205


similar to the angled ends


204


,


206


formed in the first length of tape


200


. The first angled end


204


has a first oblique side


208


and a second side


210


. The second angled end

208


of the first length of tape


200


and the two angled ends


204


,


208


of the second length of tape


202


. Preferably, the distance “b” is between 0.1 mm and 2.5 mm. More preferably, the distance “b” is between 0.1 mm and 0.4 mm. After the second removable portion


99


is removed from the sheet of glass, there is an intersection


220


formed between the angled ends


204


,


205


of the first length of tape


200


and the angled ends


204


,


205


of the second length of tape

FIG. 14



a


illustrates one embodiment


300


of a sheet of glass


2


including several lengths of tape


92


, which gives the sheet of glass a simulated “classic” style of etching. The optical film in the tape


92


appears to have multiple bevels, to give a “V-groove” appearance. A suitable tape for this embodiment is commercially available as 3M™ Accentrim™ Tape, series B200 (V-groove), from 3M Company, located in St. Paul, Minn. To form this embodiment


300


, the tape head


100


first applies a first length of tape


230


for the length of the sheet of glass


2


, as explained above. Then, the tape head


100


cuts the first angled ends


204


and second angled ends


205


in the first length of tape


230


at each intersection


220


, as explained above. The opposite ends of the first length of tape


230


are illustrated as having a 90° angle, cut relative to the length of the tape, as cut by the first cutter


116


. However, the opposite ends may also be cut obliquely to the length of the tape by the second cutter

illustrates another embodiment


310


of a sheet of glass


2


including several lengths of tape


92


which gives the sheet of glass a simulated “prairie” style of etching. The optical film in the tape


92


appears to have multiple bevels, to give a “V-groove” appearance. A suitable tape for this embodiment is commercially available as 3M™ Accentrim™ Tape, series B200 (V-groove), from 3M Company, located in St. Paul, Minn.




To form this embodiment


310


, the tape head


100


first applies a first length of tape


240


for the length of the sheet of glass

, as explained above. Next, the tape head


100


applies a second length of tape


242


for the length of the sheet of glass


2


parallel to the first length of tape


240


, as explained above. Then, the tape head


100


cuts the first angled ends


204


and second angled ends


205


in the first length of tape


240


at each intersection


220


and at the opposite ends of the first length of tape


240


, as explained above. Next, the tape head


100


cuts the first angled ends


204


and second angled ends


205


in the second length of tape


242


at each intersection


220


and at the opposite ends of the second length of tape


242


, as explained above. The tape head


100


returns to its “home position” on the tabletop


22


, as illustrated in

FIG. 1

, to allow a user to remove the first removable portion of the tape from each intersection


220


and the opposite ends of both the first length of tape


240


and the second length of tape


242


. Next, the tape head


100


moves from the “home position” to apply a third length of tape


244


and a fourth length of tape


246


parallel to the third length of tape


244


. The third length of tape


244


and fourth length of tape


246


both intersect the first length of tape


240


and the second length of tape


242


at 90°. Then, the tape head

illustrates one embodiment


320


of a sheet of glass


2


including several lengths of tape


92


which gives the sheet of glass a simulated “framed” style of etching. The optical film in the tape


92


has a single bevel appearance. A suitable tape for this embodiment is commercially available as 3M™ Accentrim™ Tape, series B100 (edge bevel), from 3M Company, located in St. Paul, Minn.




To form this embodiment

. The tape head


100


returns to its “home position” on the tabletop


22


, as illustrated in

FIG. 1

, to allow a user to remove the first removable portions of the tape from each intersection


230


of the first length of tape


250


. In this case, the first removable portion is in the shape of a triangle. Next, the tape head


100


moves from the “home position” to apply a third length of tape


254


and a fourth length of tape


256


parallel to the third length of tape


254


to intersect with the angled ends


222


,


224


of both the first length of tape


250


and the second length of tape


252


at 90° angles. Then, the tape head


100


cuts the first angled end


216


and second angled end


218


in the third length of tape


254


at each intersection


230


, as explained above. Next, the tape head


100


cuts a first angled end


216


and a second angled end


218


in the fourth length of tape


256


at each intersection


230


. Lastly, the tape head


100


returns to its “home position” on the tabletop


22


, as illustrated in

FIG. 1

, to allow a user to remove the second removable portions from the third length of tape


254

c


illustrate just a few preferred embodiments of tape applied to a sheet of glass. However, the tape applicator may create any layout of tape on a glass surface because of the flexibility of the tape head


100


and actuators


30


,


32


,


34


to move the tape head


100


at any angle along the tabletop


22


, to apply tape at any angle along the tabletop, and to cut the tape at any angle after it has been applied to the glass surface.




To operate the x-axis actuator


30


, y-axis actuator


32


, and rotary actuator


34


to move the tape head


100


, the tape applicator


10


preferably includes a computer processor and a controller for sending signals to the actuators


30


,


32


,


34


as where to move the tape head


100


relative to the tabletop


22


. For instance, a user may want to make the sheet of glass


2


illustrated in one of

FIGS. 14



a


-


14




c


. The user enters a set of commands into the computer processor as to what the tape layout should look like. The computer processor and controller then determines which way to direct the actuators


30


,


32


,


34


to move the tape head


100


to apply the tape to the glass and to cut the tape after it has been applied. The computer processor and controller preferably includes an “open loop” system, which calculates where the tape head


100


is located on the tabletop


22


, based on a known series of moves. For example, the ball screw in either the x-axis actuator


30


or y-axis actuator


32


will move the tape head


100


a known distance per one rotation of the ball screws. If the computer processor knows the initial location of the tape head


100


, like the “home position” for instance, it can determine where the final location of the tape head


100


, based on how many rotations the ball screw in the actuator actually rotated. The computer processor will send a signal to the x-axis and y-axis actuators


30


,


32


to turn the ball screws a certain number of rotations to move the tape head


100


a certain distance in a particular axis. The computer processor can also send signals to the rotary actuator


36


as to where to rotate the tape head


100


relative to the z-axis of the tabletop


22


. A suitable controller is a controller sold under the trade name Compumotor, which is commercially available from Braas Company located in St. Paul, Minn., sold under part number 6K4. Alternatively, the computer processor could include a “closed loop” system, which calculates where the tape head


100


is at all times on the tabletop


22


.




To determine the initial location of the tape head


100


on the tabletop


22


, the actuators


30


,


32


,


34


preferably include sensors to determine the location. Suitable sensors for the actuators


30


,


32


,


34


are Prox Sensors sold under the trade name Omron, which is commercially available from Braas Company located in St. Paul, Minn., sold under part number E2E-X1R5E1-M1-N.
