TECHNICAL FIELD




The present invention relates to a tape applicator including a tape head. The present invention relates more particularly to a tape applicator including a tape head comprising: a base; ii) a tape roll holder attached to the base; iii) a tape application roller attached to the base for applying the tape to a surface, where the tape head includes a tape path from the tape roll holder to the tape application roller; iv) a cutter attached to the base along the tape path between the tape roll holder and the tape applicator roller for cutting tape to form a removeable portion of a tape; and v) a remover attached to the base along the tape path between the cutter and the tape application roller for removing the removeable portion of the tape. The present invention also relates to methods of applying tape to a 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 a 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. Another example of a tape is commercially available as 3M™ Accentrim™ Tape, series B200 and series B100, from 3M Company, located in St. Paul, Minn.

120




c.






The tape head


100


includes a liner path from the edge


156


of the platen


154


to a liner take-up roller


170


. This is the path that the liner


94


follows after the tape


92


is separated from the liner


94


at the edge


156


of the platen


154


. Along this liner path, the tape head


100


includes a first liner guide roller


158


, a driven roller


161


, a nip roller


164


mounted on the end of a second arm


163

168


, all mounted to the base


101


. The driven roller


161


includes a motor (not illustrated). The driven roller


161


and the nip roller


164


form a nip for the liner


94


to travel through. Preferably, the liner take-up roller


170


includes a motor (not illustrated) to drive the roller


170


, so as to wind the liner


94


around the roller


170


. The liner take-up roller


170


preferably includes a friction clutch to provide tension on the liner


94


as it winds onto the liner take-up roller


170


, to keep the liner


94


taunt.




The tape


92


preferably moves along the following tape path within the tape head


100


: a) from the tape roll holder


102


to the driven unwind roller


106


; b) then to the first tape guide roller


108


; c) then to the second tape guide roller


110


; d) then to the nip formed between the nip roller


114


and the tension roller


116


; e) then to the first spring-loaded tape guide


120




a;


f) then between the bed roller


130


and cutter


122


; g) then to the second and third spring-loaded tape guides


120




b,




120




c;


h) then between the platen


154


and remover


140


; and i) then under the application roller


152


, which applies the tape


92


to the surface


5


. The edge


156


of the platen


154


helps separate the liner


94


from the tape


92


, as the tape


92


passes over the edge


156


and the liner


94


is pulled in a direction opposite the tape


92


being applied to the surface. After the liner


94


is separated from the rest of the tape


92


, the liner


94


moves along the following path within the tape head


100


: a) from the edge


156


of platen


154


to the first liner guide roller


158


; b) then to the nip formed between the driven roller


161


and the nip roller


164


; c) then to the wrap roller


168


; and d) then to the driven liner take-up roller


170


.




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 first arm


112


is first pivoted clockwise to allow the tape to be wound around the tension roller


116


. Then, the first arm


112


is pivoted counter clockwise to form the nip between the nip roller


114


and the tension roller


116


with the tape in the nip. The spring-loaded tape guides


120




a,




120




b,




120




c


each include two sides contacting the opposite edges of the tape. One side is stationary and the other side is slideable, yet biased with a spring against that edge of the tape. The spring-loaded side is pulled away slightly to allow the tape to pass through the tape guides


120




a,




120




b,




120




c.


Then, the spring-loaded side is released. The tape guides


120




a,




120




b,




120




c


assist in keeping the tape


92


straight just prior to its application to the surface


5


by the application roller


152


. The spring-loaded tape guides


120




b,




120




c


of the platen are preferably aligned with the spring loaded tape guide


120




a


. Next, the liner


94


is separated from the rest of the tape


92


near the edge


156


of the platen


154


. The edge


156


of the platen


154


is preferably sharp to assist in separating the liner


94


from the rest of the tape


92


. The liner is then wound through the tape head


100


according to the liner path outlined above and around the liner take-up roller


170


.





FIG. 4

illustrates one embodiment of cutter


122


. In this embodiment, the cutter is a rotary die and it is configured to cut a plurality of shapes to form removable portions of tape. However, other means of cutting known in the art may be used to cut the removable portions of tape. In this embodiment the rotary die is configured to cut three different shapes into the tape


92


. However, the rotary die


122


may be configured to cut any number of shapes. Each shape includes a different blade configuration. The first blade configuration


124




a


cuts a “butterfly” shape in the tape to form a removable portion of tape. The first blade configuration


124




a


includes a first angled blade


180


and a second angled blade


182


opposite the first angled blade


180


. Both the first angled blade


180


and the second angled blade


182


are in the shape of a “V” with the point of the “V” pointing at each other. The first angled blade


180


and second angled blade


182


are set a distance “a” away from each other at their points. Each angled blade


180


,


182


includes a first oblique side


184


and a second oblique side


186


. The oblique sides


184


,


186


are set at an angle α relative to the longitudinal axis of the cutter


122


. Angle α may be selected for a desired appearance in the blade configuration. For example, angle α may be 30°, 45°, or 60° or any other angle. Alternatively, each angled blade


180


,


182


may include different angles α. In one preferred embodiment, the angle α is 30°. Preferably, the distance “a” is between 0.5 mm and 4 mm. More preferably, the distance “a” is between 2 mm and 2.3 mm. The second blade configuration


124




b


is the same as the first blade configuration


124




a,


except that in a preferred embodiment, the angle β is 45° and the distance “b” is preferably between 0.3 mm and 3 mm, and more preferably between 0.3 mm and 0.5 mm. Alternatively, the angle β may be 30° or 60° or any other angle. The second blade configuration


124




b


also cuts the tape to form a removable portion of tape in the shape of a butterfly. The third blade configuration


124




c


includes a single blade


188


, which is perpendicular to the longitudinal axis of the cutter. With this blade, a removable portion of tape is not formed. Preferably the blade configurations


124


are equidistant around the cutter


122


or 120° relative to each other.




Even though the blade configurations illustrated in

FIGS. 4



a


-


4




c


are illustrated as having straight blades, the blades may be in any shape to provide for a variety of shapes in the removable portions.




Referring back to

FIG. 3

, the rotary die


122


is rotated about its axis by a motor (not illustrated.) A sensor


126


senses a reference mark on the rotary die


122


to locate the home position of the rotary die. Based on that home position, the motor rotates the rotary die until it aligns a desired one of the blade configurations


124


along the tape


92


. Once the selected blade configuration is close to being directly over the tape, the bed roller


130


pivots about shaft


132


to provide support for the tape about to be cut.





FIG. 5



a


is a top view of the tape


92


after it has been cut by the second blade configuration


124




b


of the cutter


122


. The second blade configuration


124




b


forms a first length of tape


160


, a second length of tape


162


, and a removable portion


98


between the first length of tape


160


and the second length of tape


162


. In this case, the first removable portion


98


is in a shape similar to a butterfly. Each end of the first and second lengths of tape


160


,


162


is angled to form angled ends


204


,


205


. The first angled end


204


of the second length of tape


162


has a first oblique side


208


and a second oblique side


210


. The second angled end


205


of the first length of tape


160


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 β relative to the length of the tape. Preferably, the angled ends


204


,


205


are cut to fit together to give the desired intersection


220


, as illustrated later in

FIGS. 12



a


and


12




b.


Angle β may be selected for a desired appearance. For example, angle β may be 30°, 45°, or 60° or any other angle. Alternatively, each angled end


204


,


205


may include different angles. There is a distance “b” between the first angled end


204


of the second length of tape and the second angled end


205


of the first length of tape


160


. Preferably, the distance “b” is between 0.3 mm and 3 mm. More preferably, the distance “b” is between 0.3 mm and 0.5 mm.





FIG. 5



b


is a top view of the tape


92


after it has been cut by an alternative blade configuration (not illustrated) of the cutter


122


. In this embodiment, the blade configuration also forms a first length of tape


160


, a second length of tape


162


, and a removable portion of tape


98


. In this case, the first removable portion


98


is in a shape similar to a triangle. Each end of the first and second lengths of tape


160


,


162


is angled to form angled ends


222


,


224


. The first angled end


222


of the second length of tape


162


has only one oblique side


208


. The second angled end


224


of the first length of tape


160


has only one oblique side


212


. The first angled end


222


and second angled end


224


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


222


,


224


are cut to fit together to give the desired intersection


230


, as illustrated later in

FIG. 12



c.


Angle δ may be selected for a desired appearance. For example, angle δ may be 30°, 45°, or 60° or any other angle. Alternatively, each angled end


222


,


224


may include different angles.





FIGS. 6-11

are useful for describing the method of applying a first length of tape to the surface


5


of a sheet of glass


2


, cutting a removable portion tape, removing the removable portion of tape, and applying the second length of tape to the surface


5


of the sheet of glass


2


.





FIG. 6

is a partial side view of the tape head


100


. Tape head


100


is applying a first length of tape


160


with a first end


204


on the surface


5


of the sheet of glass


2


in the direction of arrow C. Preferably, the first end


204


was previously cut to provide a desired angled end, however, this is not essential. Preferably, the tape head


100


is moved relative to the stationary glass surface


5


in the direction of arrow C by the x-axis or y-axis actuators, as explained above. It is also possible to move the glass relative to the stationary tape head or to move both the glass and the head. As the tape head


100


moves relative to the glass surface


5


, the tape application roller


152


presses the tape


92


against glass surface, adhering the adhesive side of the tape


92


to the glass surface. During this motion of the tape head


100


, the remover


140


is at a remote position, located away from the tape


92


and liner


94


. Also during this motion of the tape head


100


, the bed roller


130


is pivoted counterclockwise about shaft


132


at a remote position, located away from the tape


92


and liner


94


. As the tape head


100


is close to finishing applying the first length of tape


160


, the rotary die


122


rotates clockwise about its axis to start aligning one of the blade configurations


124




a


-


124




c


with the tape. When the selected blade configuration


124


is just about to make contact with the tape


92


and liner


94


, the bed roller


130


pivots clockwise about pivot


132


to provide a support surface for the tape


92


and liner


94


. Then, the selected blade configuration


124


of rotary die


122


cuts the tape


92


to form a removable portion


98


, as the rotary die continues it rotation about its axis. Preferably, the rotary die


122


pivots at approximately the same speed as the tape


92


is moving past the rotary die


122


. This is to allow the tape


92


to continue to move at the same speed without disruption by the rotary die


122


. Preferably, the rotary die


122


forms the removable portion


98


by cutting through the tape


92


, but not cutting through the liner


94


. This is to allow the removable portion


98


to stay adhered to the liner


94


until it is removed from the liner by the remover


140


in the next steps of the process, illustrated in

FIGS. 7-9

.




As the tape head


100


finishes applying the first length of tape


160


to the glass surface


5


, the tape head


100


continues to move in the same direction, by the x-axis actuator


30


or y-axis actuator


32


, whichever is appropriate, until the application roller


152


rolls over the second end


205


of the first length of tape


160


. Next, the x-axis actuator


30


or y-axis actuator


32


moves the tape head


100


to position the platen


154


directly above where the tape head will start applying the first end


204


of the second length of tape


162


on the glass surface


5


.





FIG. 7

illustrates the next series of steps. The removable portion


98


, which is located between the first length of tape


160


and the second length of tape


162


, is now positioned on the platen


154


. Preferably, the middle of the removable portion


98


is positioned over the edge


156


of the platen


154


. First, the z-axis actuator


36


moves the tape head


100


in the direction of arrow D′, which is up relative to the glass surface


5


. Second, an air cylinder (not shown) actuates the arm


146


clockwise in the direction of arrow F′, thus pivoting both the remover


140


and applying roller arm


151


clockwise. At about the same time, another air cylinder (not shown) actuates both the remover


140


and the applying roller arm


151


in the direction of arrow E′, which is up relative to the arm


146


. The surface


144


of the slider


142


of the remover


140


is now positioned directly over the removable portion


98


. Alternatively, the adhesive could be replaced by a vacuum source or some other mechanical structure for retaining the removable portion


98


of tape.





FIG. 8

illustrates the next step. In this step, the air cylinder (not shown) actuates both the remover


140


and the applying roller arm


151


down relative to the arm


146


in the direction of arrow E″ to pick up the removable portion


98


from the platen


156


. Preferably, the surface


144


on the slider


156


has a piece of double-stick adhesive tape on it. The adhesive layer facing outwards from the surface


144


sticks to the backing of the removable portion


98


of tape.





FIG. 9

illustrates the next step. In this step, the air cylinder (not shown) actuates both the remover


140


and the applying roller arm


151


back up relative to the arm


146


in the direction of arrow E′, to remove the removable portion


98


of tape from the liner


94


.





FIG. 10

illustrates the next series of steps. First, the air cylinder (not shown) actuates both the remover


140


and the applying roller arm


151


down relative to the arm


146


in the direction of arrow E″. At about the same time, the air cylinder (not shown) actuates the arm


146


counter-clockwise in the direction of arrow F″, thus pivoting both the remover


140


and applying roller arm


151


counter-clockwise. Second, the z-axis actuator


36


moves the tape head


100


down relative to the glass surface


5


in the direction of arrow D″. After this sequence of steps, the application roller


152


is positioned directly in front of the platen


154


. Third, the x-axis actuator or y-axis actuator starts moving the tape head


100


relative to the glass surface


5


in the direction of arrow C. As the tape head


100


moves, the second length of tape


162


is applied to the glass surface


5


by the application roller


152


. However, these steps may be performed in any sequence.




The steps illustrated in

FIGS. 6-10

are repeated until the desired amount of tape is applied to the surface at its desired locations. During this time, the removable portions


98


of tape are accumulated by the remover


140


, creating a stack of removable portions


98


as shown in FIG.


11


. In this stack, the adhesive side of one of the removable portions


98


of tape is adhered to the backing of an adjacent removable portion


98


of tape. As more and more removable portions


98


are accumulated, the stack becomes thicker. As the remover


140


is pressed down against the removable portion


98


of tape on the liner, the slider


142


moves successively to different positions within the channel of the remover


140


in the direction of arrow G. When the stack of removable portions


98


has filled most of the channel of the remover


140


, the stack of removable portions


98


is removed from the channel, and the slider


142


slid back down the channel to start the process again. Alternatively, the remover


140


may then be disengaged from the tape head and the stack of removable portions


98


may be removed.




To operate the x-axis actuator


30


, y-axis actuator


32


, rotary actuator


34


, and z-axis actuator


36


to move the tape head


100


, the tape applicator


10


preferably includes a controller for sending signals to the actuators


30


,


32


,


34


,


36


as where to move the tape head


100


relative to the tabletop


14


. For instance, a user may want to apply decorative tape to the sheet of glass


5


in the patterns illustrated in one of

FIGS. 12



a


-


12




c.


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


30


,


32


,


34


,


36


to move the tape head


100


to apply the tape to the glass and to select the appropriate blade configurations in the cutter to cut the tape before it has been applied. The controller preferably includes an “open loop” system, which calculates where the tape head


100


is located on the tabletop


14


, based on a known series of moves. For example, the gear 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 gear along the gear rack. If the controller knows the initial location of the tape head


100


, it can determine where the final location of the tape head


100


, based on how many rotations the gear in the actuator rotated along the gear rack. The controller will send a signal to the x-axis and y-axis actuators


30


,


32


to turn the gears a certain number of rotations to move the tape head


100


a certain distance in a particular axis. The controller can also send signals to the z-axis actuator


36


to move the tape head


100


up or down the z-axis. The controller 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


14


. 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 6K8.)




Alternatively, the controller could include a “closed loop” system, which provides continuous feedback as to the location of the tape head


100


on the tabletop


14


.




To determine the initial location of the tape head


100


on the tabletop


14


, the actuators


30


,


32


,


34


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


30


,


32


,


34


are proximity 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.





FIG. 12



a


illustrates one preferred arrangement


300


of a plurality of lengths of tape applied to a sheet of glass


2


, 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. As explained above, the actuators


30


,


32


,


34


,


36


move the tape head


100


relative to the sheet of glass


2


to apply several lengths of tape


92
